                            ------------------------

June 2, 1999

Dear Stockholder:

    You are cordially invited to attend the special meeting (the "Uniphase
Stockholders Meeting") of stockholders of Uniphase Corporation, a Delaware
corporation ("Uniphase"), which will be held at Uniphase's corporate offices at
163 Baypointe Parkway, San Jose, California 95134, on June 28, 1999, at 9:30
A.M., Pacific Time, for the purpose of considering and acting on the proposals
detailed in this letter.

    On January 28, 1999, Uniphase, 3506967 Canada Inc., a Canadian corporation,
and JDS FITEL Inc. ("JDS"), a Canadian corporation, entered into an agreement to
combine (the "Transaction") JDS and Uniphase (the "Merger Agreement"). We regard
the Transaction with JDS as an event of singular importance in the history of
Uniphase. The Transaction represents an opportunity to combine complementary
products and technologies and to achieve a broad based leadership position in
the rapidly growing demand for components and modules for the fiberoptic
telecommunications networking marketplace. Uniphase and JDS believe that a
number of market factors that affect their businesses and the business of their
common customer base cause the Transaction to be appropriate at this time and in
the best interest of both companies and their respective stockholders, both now
and over the long term.

    At the Uniphase Stockholders Meeting, you will be asked to approve the
combination of JDS and Uniphase and the transactions contemplated by the Merger
Agreement (as amended and restated as of April 29, 1999), certain related
amendments to Uniphase's amended and restated certificate of incorporation, and
an increase in the number of shares available for issuance under to the Uniphase
1998 Employee Stock Purchase Plan. These proposals are discussed in more detail
in the accompanying Uniphase Proxy Statement (the "Proxy Statement"). YOUR BOARD
OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR APPROVAL AND ADOPTION OF
EACH OF THESE MATTERS.

    In the Transaction, the holders of outstanding common shares of JDS ("JDS
Common Shares") will receive as consideration for each JDS Common Share, subject
to certain conditions, either: (i) 0.50855 of a share of Uniphase Common Stock,
par value $0.001 per share ("Uniphase Common Share"); or (ii) 0.50855 of a share
("Exchangeable Share") of a new class of stock of 3506967 Canada Inc., a newly
formed Canadian subsidiary of Uniphase. Exchangeable Shares will entitle their
holders to dividends and other rights that are, as nearly as practical,
economically equivalent to those of the Uniphase Common Shares and will also
carry the right, through a voting trust, to vote at meetings of stockholders of
Uniphase. They are also exchangeable at any time, on a one-for-one basis, for
Uniphase Common Shares at the option of the holder. The Exchangeable Share
structure is designed to provide an opportunity for shareholders of JDS to
achieve tax deferral in certain circumstances, as described in the attached
Joint Supplement to Uniphase Corporation Proxy Statement and JDS FITEL Inc.
Management Information Circular (the "Supplement").

    Other matters to be considered at the Uniphase Stockholders Meeting will
include proposals to amend the Uniphase amended and restated certificate of
incorporation to increase the number of authorized Uniphase Common Shares, to
change the name of Uniphase Corporation to "JDS Uniphase Corporation," to
increase the number of Uniphase Common Shares available for issuance under the
Uniphase 1998 Employee Stock Purchase Plan, and other routine matters.

    WE URGE YOU TO CONSIDER CAREFULLY THE IMPORTANT MATTERS DESCRIBED IN THE
ATTACHED PROXY STATEMENT AND SUPPLEMENT. The Supplement is lengthy because of
the complexity of the structure of the proposed Transaction. A summary of some
of the more important information in the Supplement concerning the Transaction
begins on page S-1 of the Supplement, and is a useful place to begin your
review.

    WHETHER OR NOT YOU ARE PERSONALLY ABLE TO ATTEND THE UNIPHASE STOCKHOLDERS
MEETING, PLEASE COMPLETE, SIGN AND DATE THE ENCLOSED PROXY CARD AND RETURN IT IN
THE ENCLOSED ENVELOPE AS SOON AS POSSIBLE. This action will not limit your right
to vote in person if you wish to attend the meeting and vote personally.

                                          Sincerely yours,

    shares to 2,500,000 shares; and

5.  To transact such other business as may properly come before the meeting or
    any adjournment or postponement thereof.

                                PROXY STATEMENT

    This Proxy Statement (the "Proxy Statement"), including the Joint Supplement
to Uniphase Corporation Proxy Statement and JDS FITEL Inc. Management
Information Circular (the "Supplement"), which forms part of and is incorporated
into this Proxy Statement, is being furnished to holders of Common Stock, par

Delaware corporation ("Uniphase"), in connection with the solicitation of
proxies by the Board of Directors of Uniphase for use at the special meeting
(the "Uniphase Stockholders Meeting") of Uniphase stockholders to be held on
June 28, 1999 and any adjournment or postponement thereof.

    The Supplement is also being furnished to holders of Common Shares ("JDS
Common Shares") of JDS FITEL Inc. ("JDS"), a Canadian corporation, in connection
with the solicitation of proxies by the management of JDS for use at the special
meeting of JDS shareholders to be held on June 28, 1999 and any adjournment or

(iii) an amendment to the Uniphase Certificate of Incorporation to change the

    SEE "RISK FACTORS" BEGINNING ON PAGE S-24 OF THE SUPPLEMENT FOR CERTAIN
               CONSIDERATIONS RELEVANT TO APPROVAL OF PROPOSAL 1.

    This Proxy Statement and the accompanying form of proxy are first being
mailed to stockholders of Uniphase on or about June 2, 1999.

    THE SECURITIES TO BE ISSUED IN THE TRANSACTIONS CONTEMPLATED BY THE MERGER
AGREEMENT HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE
COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY
OR ADEQUACY OF THIS PROXY STATEMENT. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

                The date of this Proxy Statement is May 14, 1999

REVOCATION OF PROXY

    Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is exercised by delivering to Uniphase (to the
attention of Anthony R. Muller) a written notice of revocation or a duly
executed proxy bearing a later date, or by attending the Uniphase Stockholders
Meeting and voting in person.

SOLICITATION OF PROXIES

    The solicitation of proxies will be conducted by mail and Uniphase will bear
all attendant costs. These costs will include the expense of preparing and
mailing proxy materials for the Uniphase Stockholders Meeting and reimbursements
paid to brokerage firms and others for their expenses incurred in forwarding
solicitation material regarding the Uniphase Stockholders Meeting to beneficial
owners of Uniphase Common Shares. Uniphase has retained Corporate Investor
Communications, Inc., a proxy solicitation firm, to assist in the solicitation
of proxies for a fee of $7,000 plus customary out-of-pocket expenses. Uniphase
may conduct solicitation personally, telephonically or by facsimile through its
officers, directors and regular employees, none of whom will receive additional
compensation for assisting with the solicitation.

VOTING RIGHTS

    Each outstanding Uniphase Common Share on the Record Date is entitled to one
(1) vote on all matters to be acted upon at the Uniphase Stockholders Meeting.
An automated system administered by Uniphase's transfer agent will tabulate
votes cast by proxy at the Uniphase Stockholders Meeting, and an officer of
Uniphase will tabulate votes cast in person at the meeting. Abstentions and
broker non-votes are each included in the determination of the number of shares
present, and each is tabulated separately. In determining whether a proposal has
been approved, abstentions are counted as votes against the proposal and broker
non-votes are not counted as votes for or against the proposal.

    The close of business on May 24, 1999 has been fixed as the record date (the
"Record Date") for determining the holders of Uniphase Common Shares entitled to
notice of and to vote at the Uniphase Stockholders Meeting. As of the close of
business on the Record Date, Uniphase had 40,480,490 Uniphase Common Shares
outstanding and entitled to vote at the Uniphase Stockholders Meeting. The
presence at the Uniphase Stockholders Meeting of a majority of these Uniphase
Common Shares, either in person or by proxy, will constitute a quorum for the
transaction of business at the Uniphase Stockholders Meeting.

STOCKHOLDER PROPOSALS

    Proposals of stockholders intended to be presented at the Uniphase 2000
annual meeting, and otherwise eligible, must be received by Uniphase (at the
address indicated in the accompanying notice) no later than June 16, 1999 to be
included in Uniphase's proxy material and form of proxy relating to that
meeting.

expected to be present at the Uniphase Stockholders Meeting and available to
respond to appropriate questions.

                                       3

PROPOSAL 1:  APPROVAL OF THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT

    The Merger Agreement provides for the combination of Uniphase and JDS in a
transaction in which each holder of outstanding JDS Common Shares will receive
as consideration for each JDS Common Share, subject to certain conditions,
either: (a) 0.50855 of a Uniphase Common Share, or (b) 0.50855 of a share of a
new class of stock of Exchangeco (an "Exchangeable Share"), a newly formed
Canadian subsidiary of Uniphase. As a result of the Transaction, Uniphase will
become the beneficial owner of all of the outstanding JDS Common Shares.

REASONS FOR SEEKING STOCKHOLDER APPROVAL

    The Nasdaq National Market listing requirements require that a listed issuer
obtain the consent of its stockholders prior to completing any transaction that
would result in the issuance of more than 20% of the issuer's outstanding common
stock. The transactions contemplated by the Merger Agreement provide that
Uniphase will issue shares of its Common Stock (either directly or on exchange
of Exchangeable Shares) representing, in the aggregate, in excess of 20% of its
issued and outstanding Common Stock. If Uniphase were to consummate the
transactions without stockholder approval, the Uniphase Common Shares could not
remain listed on the Nasdaq National Market. Approval of the transactions is not
required by Delaware law or Uniphase's certificate of incorporation or bylaws.

VOTE REQUIRED AND THE UNIPHASE BOARD OF DIRECTOR'S RECOMMENDATION

    The affirmative vote of a majority of all the votes cast by stockholders at
the Uniphase Stockholders Meeting at which a quorum is present is required to
adopt the proposal to approve the transactions contemplated by the Merger
Agreement.

    THE UNIPHASE BOARD OF DIRECTORS BELIEVES THAT THE TRANSACTIONS CONTEMPLATED
BY THE MERGER AGREEMENT ARE FAIR TO UNIPHASE STOCKHOLDERS AND IN THE BEST
INTERESTS OF UNIPHASE AND THE UNIPHASE STOCKHOLDERS. ACCORDINGLY, THE UNIPHASE
BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED, AND RECOMMENDS A VOTE FOR APPROVAL
OF, THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT.

    Each of the directors of Uniphase has advised Uniphase that he or she will
vote the Uniphase Common Shares held by him or her in favour of the proposal.

    The reasons for the transactions contemplated by the Merger Agreement and
the factors considered by the Uniphase Board of Directors are set out in the
Supplement under the headings "The Transaction -- Reasons for the Transaction"
and "The Transaction -- Recommendation of the Uniphase Board of Directors".

    SEE "RISK FACTORS" BEGINNING ON PAGE S-24 OF THE SUPPLEMENT FOR CERTAIN
CONSIDERATIONS RELEVANT TO APPROVAL OF PROPOSAL 1.

    Please review the Supplement carefully as it contains details regarding the
Merger Agreement, the Transaction, JDS and related matters, beginning on page
S-1.

                                       4

PROPOSAL 2:  APPROVAL OF AMENDMENT TO THE UNIPHASE CERTIFICATE OF INCORPORATION
             TO INCREASE THE NUMBER OF AUTHORIZED UNIPHASE COMMON SHARES

    On January 28, 1999, the Uniphase Board of Directors declared advisable and
approved an amendment to the Uniphase Certificate of Incorporation to increase
the aggregate number of Uniphase Common Shares which Uniphase is authorized to
issue from 100,000,000 to 200,000,000 shares. No increase in the number of
authorized shares of Uniphase Preferred Stock, currently 1,000,000 shares, is
proposed or anticipated.

    If approved by the stockholders, the amendment will become effective upon
the filing of a Certificate of Amendment of Certificate of Incorporation with
the Delaware Secretary of State. The proposed amendment would change paragraph
4.1 of Article 4 of Uniphase's Certificate of Incorporation to read in its
entirety as follows:

       "4.1.  Authorized Capital Stock.  The Corporation is authorized to
       issue two classes of stock to be designated, respectively, 'Common
       Stock' and 'Preferred Stock.' The total number of shares which the
       Corporation is authorized to issue is two hundred and one million
       (201,000,000) shares.

       Two hundred million (200,000,000) shares shall be Common Stock,
       each having a par value of one-tenth of one cent ($.001). One
       million (1,000,000) shares shall be Preferred Stock, each having a
       par value of one-tenth of one cent ($.001)."

PURPOSE AND EFFECT OF THE AMENDMENT

    As of the Uniphase Record Date, of the 100,000,000 currently authorized
Uniphase Common Shares, 40,480,490 shares were issued and outstanding and
7,506,716 shares were subject to outstanding options granted pursuant to
Uniphase option plans. The principal purpose of the proposed amendment is to
authorize additional Uniphase Common Shares which will be available (i) for
issuance upon exercise of options granted under the Uniphase compensation plans
and (ii) in the event that the Board of Directors determines that it is
necessary or appropriate to (a) effect future stock dividends or stock splits,
(b) raise additional capital through the sale of securities, (c) acquire another
company or its business or assets through the issuance of securities, or (d)
establish a strategic relationship with a corporate partner through the exchange
of securities.

    In determining to increase the authorized Uniphase Common Shares, the
Uniphase Board of Directors considered, among other factors, (i) in connection
with the Transaction, Uniphase will issue to shareholders of JDS in the
Transaction or reserve for issuance sufficient Uniphase Common Shares upon
exchange of the Exchangeable Shares and options to be granted to JDS employees,
(ii) that as of December 31, 1998, 47,274,951 Uniphase Common Shares were issued
or subject to outstanding options granted under the Uniphase compensation plans,
thereby, together with (i) above, effectively encumbering substantially all of
the 100,000,000 shares presently authorized, (iii) that there is currently
insufficient authorized Uniphase Common Shares to support anticipated option
grants in 1999 and 2000, (iv) that there is currently insufficient authorized
Uniphase Common Shares available to raise capital and to respond to potential
business opportunities and pursue important objectives, and (v) that were
Uniphase to effect a two-for-one stock split in the future, a minimum of
approximately 190,000,000 authorized shares would be required. If the proposed
amendment is adopted, the aggregate number of authorized Uniphase Common Shares
will be increased to 200,000,000, and, if the Transaction is completed,
approximately 100,000,000 additional Uniphase Common Shares will then be
available for issuance by the Uniphase Board of Directors without any further
stockholder approval, except in certain issuances of shares which require
stockholder approval in accordance with the requirements of Nasdaq National
Market or the Delaware General Corporation Law ("DGCL"). The holders of Uniphase
Common Shares have no preemptive rights to purchase any stock of Uniphase. The
additional Uniphase Common Shares might be issued at such times and under such
circumstances as to have a dilutive effect on earnings per share and on the
equity ownership of the present holders of Uniphase Common Shares.

POTENTIAL ANTI-TAKEOVER EFFECT

    The proposed amendment to increase the number of authorized Uniphase Common
Shares could, under certain circumstances, have an anti-takeover effect,
although this is not the intention of this proposed

                                       5

amendment. The increased number of authorized Uniphase Common Shares could
discourage, or be used to impede, an attempt to acquire or otherwise change
control of Uniphase. The private placement of Uniphase Common Shares into
"friendly" hands, for example, could dilute the voting strength of a party
seeking control of Uniphase. Furthermore, many companies have issued warrants or
other rights to acquire additional shares of common stock to their stockholders
to discourage or defeat unsolicited share accumulation programs and acquisition
proposals, which programs or proposals may be viewed by the board of directors
as not in the best interest of their stockholders. Although Uniphase has no
present intent to use the additional authorized Uniphase Common Shares for such
purposes, if the proposed amendment is adopted, more capital stock of Uniphase
would be available for such purposes than is currently available.

VOTE REQUIRED AND THE UNIPHASE BOARD OF DIRECTOR'S RECOMMENDATION

    The affirmative vote of the holders of a majority of Uniphase Common Shares
issued and outstanding as of the Record Date is required to adopt the proposal
to amend the Certificate of Incorporation to increase the aggregate number of
authorized Uniphase Common Shares from 100,000,000 to 200,000,000 shares.

    THE UNIPHASE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE
PROPOSAL TO AMEND THE UNIPHASE CERTIFICATE OF INCORPORATION TO INCREASE THE
NUMBER OF AUTHORIZED UNIPHASE COMMON SHARES.

PROPOSAL 3:  APPROVAL OF AMENDMENT TO THE UNIPHASE CERTIFICATE OF INCORPORATION
             TO CHANGE THE NAME FROM UNIPHASE CORPORATION TO JDS UNIPHASE
             CORPORATION

    The Uniphase Board of Directors is asking the stockholders to vote on a
proposal to amend Uniphase's Certificate of Incorporation to change the name of
Uniphase to "JDS Uniphase Corporation." The Uniphase Board of Directors has
unanimously approved such an amendment to the Certificate of Incorporation.

    The purpose of the proposed name change is to reflect the proposed
combination of Uniphase and JDS.

    Upon consummation of the proposed name change it will not be necessary to
surrender stock certificates. Instead when certificates are presented for
transfer, new certificates bearing the name JDS Uniphase Corporation will be
issued. If there exists any circumstance which would make consummation of the
name change inadvisable in the judgment of the Uniphase Board of Directors,
including the failure of the Uniphase Stockholders to approve the transactions
contemplated by the Merger Agreement or the failure of the shareholders of JDS
to approve the proposed combination of JDS and Uniphase, this proposal to amend
the Certificate of Incorporation may be terminated by the Uniphase Board of
Directors either before or after approval of the name change by the Uniphase
Stockholders.

VOTE REQUIRED AND THE UNIPHASE BOARD OF DIRECTOR'S RECOMMENDATION

    The affirmative vote of the holders of a majority of Uniphase Common Shares
issued and outstanding as of the Record Date is required to adopt the proposal
to amend the Certificate of Incorporation to effect the proposed name change.

    THE UNIPHASE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE
PROPOSAL TO AMEND THE UNIPHASE CERTIFICATE OF INCORPORATION TO CHANGE THE NAME
OF UNIPHASE CORPORATION TO "JDS UNIPHASE CORPORATION."

                                       7

PROPOSAL 4:  APPROVAL OF INCREASE IN THE NUMBER OF SHARES RESERVED FOR ISSUANCE
             PURSUANT TO THE UNIPHASE 1998 EMPLOYEE STOCK PURCHASE PLAN

    The Uniphase Board of Directors is asking the stockholders to vote on a
proposal to amend Uniphase's 1998 Employee Stock Purchase Plan (the "Plan").

    The effect of the amendment will be to increase the number of Uniphase
Common Shares available for issuance pursuant to the Uniphase 1998 Employee
Stock Purchase Plan by 1,500,000 shares, from 1,000,000 shares to 2,500,000
shares.

    The purpose of the Plan is to provide employees of Uniphase and its
corporate affiliates with an opportunity to purchase Common Stock of Uniphase
through accumulated payroll deductions. It is the intention of Uniphase to have
the Plan qualify as an "Employee Stock Purchase Plan" under Section 423 of the
Internal Revenue Code of 1986, as amended (the "Code"). The provisions of the
Plan, accordingly, shall be construed so as to extend and limit participation in
a manner consistent with the requirements of that section of the Code. The Plan
is intended to enable Uniphase and its corporate affiliates to attract and
retain the best available personnel for positions of substantial responsibility,
to provide additional incentive to employees, to promote the success of
Uniphase's business, and to increase stockholder value by further aligning the
interests of its employees with the interests of Uniphase's stockholders by
providing an opportunity to benefit from stock price appreciation that generally
accompanies improved financial performance. The Board of Directors believes that
Uniphase's long term success is dependent upon the ability of Uniphase and its
corporate affiliates to attract and retain superior individuals who, by virtue
of their ability and qualifications, make important contributions to Uniphase
and its corporate affiliates.

REASONS FOR SEEKING STOCKHOLDER APPROVAL

    Uniphase is seeking stockholder approval of the proposal to amend the Plan
pursuant to Internal Revenue Service regulations.

VOTE REQUIRED AND THE UNIPHASE BOARD OF DIRECTORS' RECOMMENDATION

    The affirmative vote of a majority of all the votes cast by stockholders at
the Uniphase Stockholders Meeting at which a quorum is present is required to
adopt the proposal to amend the Plan.

    THE UNIPHASE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE
PROPOSAL TO INCREASE THE NUMBER OF UNIPHASE COMMON SHARES RESERVED FOR ISSUANCE
PURSUANT TO THE UNIPHASE 1998 EMPLOYEE STOCK PURCHASE PLAN.

PLAN BENEFITS

    The benefits to be received pursuant to the Plan by executive officers and
employees of Uniphase and its corporate affiliates are not determinable at this
time because such benefits are based upon each individual's determination of
whether or not to participate in the plan and to what extent.

    A general description of the principal terms of the Plan as proposed is set
forth below. This description is qualified in its entirety by the terms of the
Plan.

GENERAL DESCRIPTION

    The purpose of the Plan is to provide employees of Uniphase and its
corporate affiliates who participate in the Plan with an opportunity to purchase
Uniphase Common Shares through payroll deductions. The Plan, and the right of
participants to make purchases thereunder, is intended to qualify as an
"employee stock purchase plan" under the provisions of Section 423 the Code.
Employees of Uniphase and its corporate affiliates are eligible to participate
in the Plan. Directors who are not employees are not eligible to participate.
Following the Transaction, the number of executive officers and employees of
Uniphase and its corporate affiliates eligible to participate in the Plan will
be approximately 4,200 persons.

    Any person who is employed by Uniphase or any corporate affiliates
designated by the Board for more than 20 hours per week and more than five
months in a calendar year is eligible to participate in the Plan provided

                                       8

that the employee is employed on the first day of a Purchase Period (as defined
below) and subject to certain limitations imposed by Section 423(b) of the Code.
Eligible employees become participants in the Plan by delivering to Uniphase a
purchase agreement and payroll deduction authorization prior to the commencement
of the applicable Purchase Period.

    Uniphase Common Shares are offered for purchase through a series of
successive or overlapping purchase periods (the "Purchase Periods"), each of a
duration (not to exceed six months) to be determined by the Plan Administrator.
Each eligible employee who elects to participate in the Plan for a particular
Purchase Period is granted a purchase right on the first day of that Purchase
Period. The purchase right will entitle the participating employee to specify a
level of payroll deduction (between 1% and 10% of Base Compensation) to be in
effect on each pay day during the Purchase Period, and the amount of these
periodic deductions will be applied to the purchase of Uniphase Common Shares on
each purchase date.

    Outstanding purchase rights will be automatically exercised in (i)
successive quarterly installments on the last day of each fiscal quarter, in the
case of quarterly purchase dates, or (ii) successive semi-annual installments on
the last day of each alternate fiscal quarter, in the case of semi-annual
purchase dates. The purchase right will be exercised by applying the amount
credited to the employee's account to the purchase of whole Uniphase Common
Shares on each quarterly or semi-annual purchase date. The purchase price per
share will be the lesser of (i) 85% of the fair market value per Uniphase Common
Share on the date the Purchase Period begins or (ii) 85% of the fair market
value per Uniphase Common Share on the date the Uniphase Common Share is
purchased on the quarterly or semiannual purchase date. The fair market value
per Uniphase Common Share on any relevant date under the Plan will be the mean
of the highest bid and the lowest asked prices (or, if not available the closing
selling price per share) on that date, as reported on the Nasdaq National
Market, or the closing selling price on such date on such other exchange on
which Uniphase Common Shares are traded.

    Notwithstanding the foregoing, (i) no employee will be permitted to
subscribe for shares under the Plan if, immediately after the grant of the
option, the employee would own 5% or more of the voting power or value of all
classes of stock of Uniphase or any of its corporate affiliates (including stock
which may be purchased under the Plan or pursuant to any other options), (ii) no
employee shall be granted an option which would permit the employee to buy
pursuant to the Plan more than $25,000 worth of stock (determined at the fair
market value of the shares at the time the option is granted) in any calendar
year, and (iii) employees shall not be permitted in any Purchase Period to
purchase more than 5,000 shares.

    A participant may decrease the rate of his or her payroll deduction for the
remainder of a Purchase Period by filling out the appropriate form and
delivering it to the Plan Administrator. The reduced rate will become effective
as soon as practicable following the filing of such form. Each participant shall
be permitted such a rate reduction only four times in each Purchase Period. The
reduced rate shall continue in effect for the entire Purchase Period and for
each subsequent Purchase Period, unless the participant designates a different
rate (up to the 10% maximum) by filing the appropriate form with the Plan
Administrator. The new rate will become effective for the first Purchase Period
commencing after the filing of such form.

    A participant's interest in a given Purchase Period may be terminated in
whole, but not in part, by signing and delivering to the Plan Administrator the
prescribed notification form for withdrawal from the Purchase Plan. Such
withdrawal may be elected at any time prior to the end of the applicable
Purchase Period. Any withdrawal by the participant of accumulated payroll
deductions for a given Purchase Period automatically terminates the
participant's interest in that Purchase Period. The failure to remain in the
continuous employ of Uniphase (or a corporate affiliate) for more than 20 hours
per week and more than five months in a calendar year during an Purchase Period
will be deemed to be a withdrawal from that Purchase Period.

    No rights or accumulated payroll deductions of a participant under the Plan
may be pledged, assigned or transferred for any reason and any such attempt may
be treated by Uniphase as an election to withdraw from the Plan.

    The Plan may be amended at any time by the Uniphase Board of Directors,
although certain amendments would require stockholder approval. The Plan will
terminate on the earlier of August 1, 2008 or on the date on which all shares
available under the Plan have been sold, unless earlier terminated by the
Uniphase Board of Directors.

                                       9

CERTAIN FEDERAL TAX CONSEQUENCES

    The following discussion summarizes certain tax considerations for
participants in the Plan and certain tax effects to Uniphase. State and local
tax consequences may differ.

    Amounts deducted from a participant's pay under the Plan are part of the
employee's regular compensation and remain subject to federal, state and local
income and employment withholding taxes. A participant will not recognize any
additional income at the time the participant elects to participate in the Plan,
or purchases Uniphase Common Shares under the Plan.

    If a participant disposes of Uniphase Common Shares purchased pursuant to
the Plan within two (2) years after the first day of the Purchase Period or
within one (1) year of the purchase of Uniphase Common Shares (the "Minimum
Holding Period"), the participant will recognize, for federal tax purposes,
ordinary compensation income at the time of disposition of Uniphase Common
Shares in an amount equal to the excess of the fair market value of Uniphase
Common Shares on the day Uniphase Common Shares were purchased over the purchase
price the participant paid for Uniphase Common Shares. This amount may be
subject to withholding for taxes. In addition, a participant generally will
recognize a capital gain or loss in an amount equal to the difference between
the amount realized upon the disposition of Uniphase Common Shares and the
participant's basis in Uniphase Common Shares (that is, the purchase price plus
the amount taxed as compensation income).

    If a participant disposes of Uniphase Common Shares purchased pursuant to
the Plan at any time after the Minimum Holding Period, the participant will
recognize, for federal tax purposes, ordinary compensation income at the time of
such disposition in an amount equal to the lesser of (a) the excess (or zero if
there is no excess) of the fair market value of Uniphase Common Shares at the
time of such disposition over the amount paid for Uniphase Common Shares, or (b)
15% of the fair market value of Uniphase Common Shares on the first day of the
Purchase Period. In addition, the participant generally will recognize a capital
gain or loss in an amount equal to the difference between the amount realized
upon the disposition of Uniphase Common Shares and the participant's basis in
the stock (that is, the purchase price plus the amount, if any, taxed as
compensation income).

    Although the amounts deducted from a participant's pay under the Plan
generally are tax-deductible business expenses of Uniphase, Uniphase generally
will not be allowed any additional deduction by reason of a participant's
purchase of Uniphase Common Shares under the Plan. However, if a participant
disposes of Uniphase Common Shares purchased pursuant to the Plan within the
Minimum Holding Period, Uniphase should be entitled to a deduction in an amount
equal to the compensation income recognized by the participant. If a participant
disposes of Uniphase Common Shares purchased under the Plan after the Minimum
Holding Period, Uniphase will not receive any deduction for federal income tax
purposes with respect to Uniphase Common Shares.

                                      S-1

THE TRANSACTION

GENERAL

    The Merger Agreement provides for the combination of Uniphase and JDS in a
transaction in which each JDS Shareholder (other than JDS Shareholders who
properly exercise their Dissent Rights) who is a Canadian Resident will
effectively have the choice of receiving 0.50855 of a Uniphase Common Share or
0.50855 of an Exchangeable Share for each JDS Common Share held. Such JDS
Shareholder must choose to receive either Exchangeable Shares or Uniphase Common
Shares and will not be permitted to choose to receive a combination thereof. Any
JDS Shareholder (other than JDS Shareholders who properly exercise their Dissent
Rights) who is not a Canadian Resident will not be entitled to receive
Exchangeable Shares and will receive 0.50855 of a Uniphase Common Share for each
JDS Common Share held. Any JDS Shareholder (other than JDS Shareholders who
properly exercise their Dissent Rights) who is a Canadian Resident and who does
not make an effective election will receive 0.50855 of an Exchangeable Share for
each JDS Common Share held. The mechanics of the transaction will involve an
amalgamation of JDS, Amalgamation Subco and the Holding Companies, if any, by
virtue of which JDS Shareholders will receive Class B Non-Voting Preference
Shares of Exchangeco which will immediately be exchanged for Exchangeable Shares
or Uniphase Common Shares with the result set forth above.

    The Exchangeable Shares will be securities issued by Exchangeco. Holders of
the Exchangeable Shares will be entitled to dividend and other rights that are,
as nearly as practicable, economically equivalent to those of the Uniphase
Common Shares. Through a voting trust, holders of the Exchangeable Shares will
be entitled to vote at meetings of Uniphase Stockholders.

    JDS Options will become Replacement Options to purchase a number of Uniphase
Common Shares equal to the Exchange Ratio multiplied by the number of JDS Common
Shares subject to such JDS Options.

    Uniphase and its affiliates do not currently own any JDS Common Shares and
are prohibited under the Merger Agreement from acquiring any JDS Common Shares
prior to the Effective Date without the prior consent of JDS. Based on the
number of JDS Common Shares outstanding on January 27, 1999, immediately
following the completion of the Transaction, the former holders of JDS Common
Shares will hold an aggregate of approximately 39.7 million Exchangeable Shares
and Uniphase Common Shares. Assuming all JDS Common Shares are exchanged for
Uniphase Common Shares and based upon the number of JDS Common Shares and
Uniphase Common Shares outstanding as of January 27, 1999, immediately following
completion of the Transaction existing JDS Shareholders would hold approximately
50% of the outstanding Uniphase Common Shares.

    See "The Transaction", "Transaction Mechanics", "Description of Exchangeable
Shares" and "Exchangeco Share Capital".

THE COMPANIES AFTER THE TRANSACTION

    Following completion of the Transaction, JDS Uniphase will operate the
business of JDS in combination with the existing business of Uniphase. The
following chart shows the structural corporate relationship among JDS Uniphase
and its material subsidiaries following completion of the Transaction. See "The
Companies after the Transaction".

(1) The change of name of Uniphase is subject to Uniphase Stockholder approval
    of the Uniphase Additional Proposals.

(2) Uniphase Nova Scotia will be indirectly, wholly-owned by JDS Uniphase
    through a Delaware holding company.

(3) See "Business of Uniphase -- General" for a description of Uniphase's
    material operating divisions.

(4) 100% of the voting shares of Exchangeco and JDS will be held indirectly by
    JDS Uniphase.

(5) Pursuant to the Arrangement, JDS will amalgamate with Amalgamation Subco and
    the Holding Companies, if any, under the laws of Canada. JDS will have no
    material subsidiaries.

RECOMMENDATION OF THE UNIPHASE BOARD OF DIRECTORS

    THE UNIPHASE BOARD OF DIRECTORS BELIEVES THAT THE TRANSACTION IS FAIR TO
UNIPHASE STOCKHOLDERS AND IN THE BEST INTERESTS OF UNIPHASE AND THE UNIPHASE
STOCKHOLDERS. ACCORDINGLY, THE UNIPHASE BOARD OF DIRECTORS HAS UNANIMOUSLY
APPROVED THE TRANSACTION AND RECOMMENDS THAT UNIPHASE STOCKHOLDERS VOTE FOR
APPROVAL OF THE UNIPHASE TRANSACTION PROPOSAL.

    In making its recommendation, the Uniphase Board of Directors considered a
number of factors, including:

    (i) the BT Alex. Brown Fairness Opinion to the effect that, as of the date
        of such opinion, the consideration to be paid by Uniphase to JDS
        Shareholders was fair, from a financial point of view, to Uniphase
        Stockholders;

    (ii) the trading prices of the Uniphase Common Shares and the JDS Common
         Shares prior to January 28, 1999;

   (iii) the opportunity afforded by the Transaction for Uniphase to combine its
         operations with those of JDS; and

    (iv) the terms and conditions of the Merger Agreement generally, including
         the circumstances in which the Break Fee is payable by and to Uniphase,
         and the fact that the terms of the Merger Agreement and the Furukawa
         Support Agreement do not prevent a third party from making a competing
         offer or proposing a competing transaction.

    See "The Transaction -- Reasons for the Transaction" and "The
Transaction -- Recommendation of the Uniphase Board of Directors".

                                      S-3

OPINION OF UNIPHASE'S FINANCIAL ADVISOR

    On January 28, 1999, BT Alex. Brown provided its opinion that, as of such
date, based upon and subject to the assumptions made, matters considered and
limitations set forth in the BT Alex. Brown Fairness Opinion, the consideration
to be paid by Uniphase to JDS Shareholders was fair, from a financial point of
view, to the Uniphase Stockholders. The BT Alex. Brown Opinion does not
constitute an opinion as to the value of the Uniphase Common Shares or the
Exchangeable Shares or the prices at any time at which the Uniphase Common
Shares or the Exchangeable Shares will trade. No restrictions or limitations
were imposed by the Uniphase Board of Directors upon BT Alex. Brown with respect
to the investigations made or the procedures followed by BT Alex. Brown in
rendering its opinion. BT Alex. Brown was not requested by the Uniphase Board of
Directors to make any recommendation as to the form or amount of consideration
to be paid by Uniphase pursuant to the Merger Agreement, which issues were
resolved in arm's length negotiations between Uniphase and JDS. See "The
Transaction -- Opinion of Uniphase's Financial Advisor".

RECOMMENDATION OF THE JDS BOARD OF DIRECTORS

    THE JDS BOARD OF DIRECTORS BELIEVES THAT THE ARRANGEMENT IS FAIR TO JDS
SHAREHOLDERS AND IS IN THE BEST INTERESTS OF JDS. ACCORDINGLY, THE JDS BOARD OF
DIRECTORS HAS UNANIMOUSLY APPROVED THE ARRANGEMENT AND RECOMMENDS THAT JDS
SHAREHOLDERS VOTE FOR APPROVAL OF THE JDS ARRANGEMENT RESOLUTION.

    In making its recommendation, the JDS Board of Directors considered a number
of factors, including:

    (i) the Exchange Ratio offered by Uniphase which, based upon the closing
        price as of January 27, 1999 of Uniphase Common Shares and an exchange
        rate of Cdn.$1.5199 for U.S.$1.00, represented an estimated value of
        Cdn.$59.61 per JDS Common Share and a premium of approximately 23.9% to
        the preceding 20 day average trading price on the TSE of the JDS Common
        Shares;

    (ii) the CIBC World Markets Fairness Opinion to the effect that, as of the
         date of such opinion, the Transaction was fair from a financial point
         of view to JDS Shareholders;

   (iii) the fact that Furukawa, a substantial JDS Shareholder, has agreed to
         vote in favor of the Arrangement;

    (iv) the trading prices of the Uniphase Common Shares and the JDS Common
         Shares prior to January 28, 1999;

    (v) the opportunity afforded by the Arrangement for JDS to combine its
        operations with those of Uniphase;

    (vi) the structure of the Arrangement which effectively (A) permits JDS
         Shareholders who are Canadian Residents to elect to receive
         Exchangeable Shares without realizing a gain provided the adjusted cost
         base of the JDS Shareholder's JDS Common Shares exceeds the sum of any
         cash received in lieu of fractional Exchangeable Shares and the fair
         market value of the Ancillary Rights and Exchangeable Share Rights
         received on the exchange and (B) permits JDS Shareholders who are
         Canadian Residents and who elect to receive Exchangeable Shares to hold
         the Exchangeable Shares in their registered pension plans, RRSPs, RRIFs
         and DPSPs; and

   (vii) the terms and conditions of the Merger Agreement generally, including
         the circumstances in which the Break Fee is payable by and to JDS, and
         the fact that the terms of the Merger Agreement do not prevent a third
         party from making a competing offer or proposing a competing
         transaction.

    See "The Transaction -- Reasons for the Transaction", "The
Transaction -- Recommendation of the JDS Board of Directors" and "The
Transaction -- Eligibility for Investment in Canada".

OPINION OF JDS' FINANCIAL ADVISOR

    On January 28, 1999, CIBC World Markets provided its opinion that, as of
such date, based upon and subject to the various considerations set forth in the
CIBC World Markets Fairness Opinion, the Transaction was fair, from a financial
point of view, to the JDS Shareholders. The CIBC World Markets Fairness Opinion
does not constitute an opinion as to the value of the JDS Common Shares or the
prices at any time at which the JDS Common Shares, the Uniphase Common Shares or
the Exchangeable Shares will trade. No restrictions or limitations were imposed
by the JDS Board of Directors upon CIBC World Markets with respect to the
investigations made or the procedures followed by CIBC World Markets in
rendering its opinion. CIBC World

                                      S-4

Markets was not requested by the JDS Board of Directors to make any
recommendation as to the form or amount of consideration to be paid pursuant to
the Merger Agreement, which issues were resolved in arm's length negotiations
between JDS and Uniphase. See "The Transaction -- Opinion of JDS' Financial
Advisor".

INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION

    In considering the respective recommendations of the Uniphase Board of
Directors and the JDS Board of Directors with respect to the Transaction,
Uniphase Stockholders and JDS Shareholders should each be aware that certain
members of the management and board of directors of each of Uniphase and JDS
have certain interests in the Transaction, including those referred to under the
heading "The Transaction -- Interests of Certain Persons in the Transaction",
that may present them with actual or potential conflicts of interest in
connection with the Transaction. Each of the Uniphase Board of Directors and the
JDS Board of Directors was aware of these interests and considered them along
with the other matters described in "The Transaction -- Recommendation of the
Uniphase Board of Directors" and "The Transaction -- Recommendation of the JDS
Board of Directors".

FURUKAWA SUPPORT AGREEMENT

    The Uniphase Parties have entered into the Furukawa Support Agreement with
Furukawa and JDS pursuant to which Furukawa has irrevocably agreed, among other
matters, to vote its JDS Common Shares in favor of the Arrangement or any JDS
Alternative Transaction, to vote its JDS Common Shares against any Inconsistent
Transaction and, with the exception of certain permitted transfers, not to sell
or otherwise transfer any of its JDS Common Shares prior to the Effective Time
without the prior consent of Uniphase. Furukawa is permitted to sell up to 14%
of its JDS Common Shares (or approximately 7% of the outstanding JDS Common
Shares) prior to the Effective Time, provided that Furukawa either retains the
right to vote or to cause to be voted such JDS Common Shares in connection with
the Arrangement or obtains the written agreement of the transferee to be bound
by the provisions of the Furukawa Support Agreement regarding (i) the voting of
such JDS Common Shares in connection with the Arrangement and (ii) the
restrictions regarding transfers of such JDS Common Shares prior to the
Effective Time. In accordance with this provision, on February 16, 1999,
Furukawa sold 3,130,000 JDS Common Shares (approximately 4% of the outstanding
JDS Common Shares).

    The obligations of Furukawa to support the Arrangement and to perform
certain of its obligations contained in the Furukawa Support Agreement are
subject to certain conditions.

    In addition, Furukawa has agreed that neither it nor any of its Affiliates
shall, without the prior written consent of Uniphase, transfer, directly or
indirectly, after the Effective Date, Exchangeable Shares or Uniphase Common
Shares representing 10% or more of the total combined voting power of the then
outstanding Exchangeable Shares and Uniphase Common Shares, taken together, to
any one Person that is (i) a Uniphase competitor as described in Uniphase's most
recent Form 10-K or any subsequent filing made by Uniphase with the SEC; or (ii)
a Person, who directly or indirectly, has either (A) previously sought to
acquire a controlling interest (being 50% of the total combined voting power) in
a publicly traded corporation through a hostile tender offer or other structure
not approved by the board of directors of the target corporation, and who
Uniphase reasonably determines based upon credible external information intends
to make such a hostile bid to acquire a controlling interest in Uniphase or (B)
publicly disclosed an intention to acquire, directly or indirectly, any
combination of Uniphase Common Shares and Exchangeable Shares representing more
than 50% of the total combined voting power of the then outstanding Uniphase
Common Shares and Exchangeable Shares taken together.

    The Furukawa Support Agreement provides that the Uniphase Parties and a
wholly-owned subsidiary or subsidiaries of Furukawa will enter into the Furukawa
Registration Rights Agreement on or before the Effective Date. Pursuant to the
Furukawa Registration Rights Agreement, upon request, Uniphase or Exchangeco, as
the case may be, will register or qualify Uniphase Common Shares or Exchangeable
Shares held by a subsidiary of Furukawa (or its permitted transferees) under
United States securities laws (with respect to the Uniphase Common Shares) or
Canadian securities laws (with respect to the Exchangeable Shares) in order to
facilitate the sale of such shares.

    See "The Transaction -- Furukawa Support Agreement".

                                      S-5

APPROVALS REQUIRED

UNIPHASE STOCKHOLDER APPROVAL

    The Uniphase Meeting will be held on June 28, 1999. At the Uniphase Meeting,
the Uniphase Stockholders will be asked to approve the Uniphase Transaction
Proposal, which must be approved by the affirmative vote of the holders of a
majority of the total votes cast at the Uniphase Meeting at which a quorum is
present. In addition, the Uniphase Stockholders will be asked to approve the
Uniphase Additional Proposals. See "The Transaction -- Shareholder Approval and
the Special Meetings".

JDS SHAREHOLDER APPROVAL

    The JDS Meeting will also be held on June 28, 1999. At the JDS Meeting, the
JDS Shareholders will be asked to approve the JDS Arrangement Resolution.
Pursuant to the Interim Order, the JDS Arrangement Resolution must be approved
by 66 2/3% of the votes cast by holders of JDS Common Shares present or voting
by proxy at the JDS Meeting. Furukawa has agreed to vote 40,489,670 JDS Common
Shares (including the 3,130,000 JDS Common Shares it sold on February 16, 1999),
representing approximately 52% of the outstanding JDS Common Shares, in favor of
the Arrangement. See "The Transaction -- Furukawa Support Agreement" and "The
Transaction -- Shareholder Approval and the Special Meetings".

COURT APPROVAL

    An arrangement under the CBCA requires approval by the Court. Prior to the
mailing of the JDS Circular, JDS obtained the Interim Order providing for the
calling and holding of the JDS Meeting and other procedural matters. Subject to
the approval of the JDS Arrangement Resolution by the JDS Shareholders at the
JDS Meeting and the approval of the Uniphase Transaction Proposal by the
Uniphase Stockholders at the Uniphase Meeting, the hearing in respect of the
Final Order is scheduled to take place on or about June 30, 1999 at 10:00 a.m.
(Toronto time) in the Court at 393 University Ave., Toronto, Ontario. See "The
Transaction -- Court Approval of the Arrangement and Completion of the
Transaction".

THE EXCHANGEABLE SHARES

GENERAL

    The Exchangeable Shares are intended to be economically equivalent to the
Uniphase Common Shares. The dividend and other rights attaching to the
Exchangeable Shares, including the Ancillary Rights, the Call Rights and the
Exchangeable Share Rights, place holders of Exchangeable Shares, as nearly as
practicable, in the same economic position as holders of Uniphase Common Shares.

    The Ancillary Rights, consisting of the Automatic Exchange Right, the
Exchange Right and the Voting Rights, are rights established for the benefit of
the holders of Exchangeable Shares pursuant to the Voting and Exchange Trust
Agreement which are intended to permit such holders to have voting rights
equivalent to the voting rights of holders of the Uniphase Common Shares (by the
operation of the Voting Rights) and to ensure that such holders receive Uniphase
Common Shares in the event of (i) a Uniphase Liquidation Event (by the operation
of the Automatic Exchange Right) or (ii) an Exchangeco Insolvency Event (by the
operation of the Exchange Right). The Call Rights, consisting of the Liquidation
Call Right, the Redemption Call Right and the Retraction Call Right, are rights
established in favour of Uniphase Nova Scotia to allow it to purchase
Exchangeable Shares (i) in the event of the liquidation, dissolution or
winding-up of Exchangeco (by the operation of the Liquidation Call Right), or
(ii) that would otherwise be redeemed (by the operation of the Redemption Call
Right or the Retraction Call Right) by Exchangeco. The consideration received by
a holder of Exchangeable Shares will be the same whether such holders'
Exchangeable Shares are redeemed by Exchangeco or purchased by Uniphase Nova
Scotia. The Canadian federal tax consequences of a redemption or retraction,
however, differ from those of a purchase. See "Description of Exchangeable
Shares" and "Tax Considerations for JDS Shareholders -- Canadian Federal Income
Tax Consequences for JDS Shareholders".

VOTING, DIVIDEND AND LIQUIDATION RIGHTS

    Holders of Exchangeable Shares will have the right at any time to exchange
each Exchangeable Share for one Uniphase Common Share. Pursuant to the Voting
and Exchange Trust Agreement, Uniphase will issue the Special Voting Share to
the Trustee for the benefit of the holders (other than Uniphase and its
Affiliates) of the

                                      S-6

Exchangeable Shares. The Special Voting Share will have a number of votes, which
may be cast at any meeting at which Uniphase Stockholders are entitled to vote,
equal to the number of Exchangeable Shares outstanding from time to time (other
than Exchangeable Shares held by Uniphase and its Affiliates). Each such holder
of an Exchangeable Share (other than Uniphase and its Affiliates) on the record
date for any meeting at which Uniphase Stockholders are entitled to vote will be
entitled to instruct the Trustee to exercise one of the votes attached to the
Special Voting Share for each Exchangeable Share held by such holder.

    Holders of Exchangeable Shares will be entitled to receive, subject to
applicable law, dividends economically equivalent to all dividends paid on the
Uniphase Common Shares. The Exchangeable Share Support Agreement will restrict
Uniphase from declaring or paying dividends on Uniphase Common Shares unless
equivalent dividends are paid on the Exchangeable Shares, subject to applicable
law. Cash dividends on the Exchangeable Shares are payable in U.S. dollars or
the Canadian Dollar Equivalent thereof, at the option of Exchangeco. The
declaration date, record date and payment date for dividends on the Exchangeable
Shares will be the same as the relevant date for the corresponding dividends on
the Uniphase Common Shares. The Exchangeable Shares will have no additional
economic or voting rights in Exchangeco, except as required by law or under the
Exchangeable Share Support Agreement, the Exchangeable Shares Provisions with
respect to the amendment thereof or the Voting and Exchange Trust Agreement.

    Holders of Exchangeable Shares will have certain rights to receive Uniphase
Common Shares in the event of any liquidation, dissolution or winding-up of
Exchangeco or Uniphase or any other distribution of the assets of Exchangeco or
Uniphase for the purpose of winding-up its respective affairs.

    See "Transaction Mechanics" and "Description of Exchangeable Shares".

EXCHANGE OF EXCHANGEABLE SHARES FOR UNIPHASE COMMON SHARES

    Subject to the exercise by Uniphase Nova Scotia of its Retraction Call
Right, holders of the Exchangeable Shares will be entitled at any time following
the Effective Time to retract (i.e. require Exchangeco to redeem) any or all of
the Exchangeable Shares held by such holder for a retraction price per share
equal to the Retraction Price. Holders of the Exchangeable Shares may effect
such retraction by presenting: (i) a certificate or certificates to Exchangeco
or the Trustee representing the number of Exchangeable Shares the holder desires
to retract; (ii) a duly executed Retraction Request indicating the number of
Exchangeable Shares the holder desires to retract and the Retraction Date and
acknowledging the Retraction Call Right; and (iii) such other documents as may
be required to effect the retraction of the Retracted Shares.

    When a holder requests Exchangeco to redeem Retracted Shares, Uniphase Nova
Scotia will have an overriding Retraction Call Right to purchase on the
Retraction Date all but not less than all of the Retracted Shares, at a purchase
price per share equal to the Retraction Price. Upon receipt of a Retraction
Request, Exchangeco will immediately notify Uniphase Nova Scotia of the
Retraction Request. Uniphase Nova Scotia must then advise Exchangeco within five
Business Days as to whether the Retraction Call Right will be exercised. If
Uniphase Nova Scotia advises Exchangeco that Uniphase Nova Scotia will exercise
the Retraction Call Right within such five Business Day period, then provided
the Retraction Request is not revoked by the holder as described below, the
Retraction Request shall thereupon be considered only to be an offer by the
holder to sell the Retracted Shares to Uniphase Nova Scotia in accordance with
the Retraction Call Right.

    See "Description of Exchangeable Shares -- Retraction".

MANDATORY EXCHANGE OF EXCHANGEABLE SHARES FOR UNIPHASE COMMON SHARES

    Subject to applicable law and the Redemption Call Right, on the Redemption
Date, Exchangeco will redeem all but not less than all of the then outstanding
Exchangeable Shares for a redemption price per share equal to the Redemption
Price. Exchangeco will, at least 60 days prior to the Redemption Date, or such
number of days as the board of directors of Exchangeco may determine to be
reasonably practicable in respect of a Redemption Date arising in connection
with, among other events, a Uniphase Control Transaction, an Exchangeable Share
Voting Event or an Exempt Exchangeable Share Voting Event, provide the
registered holders of the Exchangeable Shares with written notice of the
proposed redemption of the Exchangeable Shares by Exchangeco or the purchase of
the Exchangeable Shares by Uniphase Nova Scotia pursuant to the Redemption Call
Right described below.

                                      S-7

    Uniphase Nova Scotia will have an overriding Redemption Call Right to
purchase on the Redemption Date all but not less than all of the Exchangeable
Shares then outstanding (other than Exchangeable Shares held by affiliates of
Uniphase) for a purchase price per share equal to the Redemption Price. Upon the
exercise of the Redemption Call Right, holders will be obligated to sell their
Exchangeable Shares to Uniphase Nova Scotia. If Uniphase Nova Scotia exercises
the Redemption Call Right, Exchangeco's right and obligation to redeem the
Exchangeable Shares on such Redemption Date will terminate.

    See "Description of Exchangeable Shares -- Redemption".

EARLY REDEMPTION

    In certain circumstances, Exchangeco has the right to require a redemption
of the Exchangeable Shares prior to March 31, 2014. Subject to the terms and
conditions of the Furukawa Support Agreement (which provides Furukawa with
certain consent rights) and the Redemption Call Right, an early redemption may
occur upon:

    (i) there being fewer than 992,372 Exchangeable Shares outstanding (other
        than Exchangeable Shares held by Uniphase and its Affiliates), provided
        that such number may be adjusted by the board of directors of Exchangeco
        in certain circumstances described in the Exchangeable Share Provisions;

    (ii) the occurrence of a Uniphase Control Transaction, provided that the
         board of directors of Exchangeco determines (A) that it is not
         reasonably practicable to substantially replicate the terms and
         conditions of the Exchangeable Shares in connection with the Uniphase
         Control Transaction and (B) that the redemption of the Exchangeable
         Shares is necessary to enable the completion of the Uniphase Control
         Transaction;

   (iii) a proposal being made for an Exchangeable Share Voting Event, provided
         that the board of directors of Exchangeco determines that it is not
         reasonably practicable to accomplish the business purpose intended by
         the Exchangeable Share Voting Event (which business purpose must be
         BONA FIDE and not for the primary purpose of causing the occurrence of
         a Redemption Date) in any other commercially reasonable manner that
         does not result in an Exchangeable Share Voting Event; or

    (iv) the failure by the holders of the Exchangeable Shares to approve or
         disapprove, as applicable, an Exempt Exchangeable Share Voting Event.

    See "Description of Exchangeable Shares -- Early Redemption".

EXCHANGEABLE SHARE RIGHTS

    Prior to the Effective Time, Exchangeco will adopt an Exchangeable Share
rights plan substantially equivalent to the Uniphase Rights Agreement. Pursuant
thereto, each Exchangeable Share issued in the Arrangement will have an
associated Exchangeable Share Right entitling the holder of such Exchangeable
Share Right to acquire additional Exchangeable Shares on terms and conditions
substantially the same as the terms and conditions upon which a holder of
Uniphase Common Shares is entitled to acquire either a Uniphase Unit or, in
certain circumstances, Uniphase Common Shares (with the definitions of
beneficial ownership, the calculation of percentage ownership and the number of
shares outstanding and related provisions applying, as appropriate, to Uniphase
Common Shares and Exchangeable Shares as though they were the same security).
The Exchangeable Share Rights are intended to have characteristics essentially
equivalent in economic effect to the Uniphase Rights. See "Description of
Exchangeable Shares -- Exchangeable Share Rights" and "Uniphase Capital
Stock -- Uniphase Rights Agreement".

THE MERGER AGREEMENT

COVENANTS REGARDING NON-SOLICITATION

    Pursuant to the Merger Agreement, each of Uniphase and JDS has agreed that
it shall not, directly or indirectly, through any officer, director, employee,
representative, financial advisor or agent of Uniphase or JDS, as the case may
be, or any of its respective subsidiaries: (i) solicit, initiate or knowingly
encourage (including by way of furnishing information or entering into any form
of agreement, arrangement or understanding) the initiation of any Acquisition
Proposal or inquiries or proposals in connection therewith; (ii) participate in
any discussions or negotiations regarding any Acquisition Proposal; (iii)
withdraw or modify the approval of the

                                      S-8

Uniphase Board of Directors or the JDS Board of Directors, as the case may be,
of the Transaction in a manner adverse to the other; (iv) approve or recommend
any Acquisition Proposal; or (v) cause Uniphase or JDS, as the case may be, to
enter into any agreement related to any Acquisition Proposal. Notwithstanding
the foregoing, the Uniphase Board of Directors or the JDS Board of Directors may
consider, negotiate, approve, recommend or enter into an agreement in respect of
a Superior Proposal. Uniphase and JDS must notify each other of all Acquisition
Proposals.

    Uniphase and JDS have each agreed not to accept, approve, recommend or enter
into any agreement in respect of an Acquisition Proposal (other than a
non-disclosure agreement) on the basis that it would constitute a Superior
Proposal unless: (i) it has provided the other party with a copy of the
Acquisition Proposal document which the board of directors of the recipient of
the Acquisition Proposal has determined would be a Superior Proposal; and (ii)
five Business Days shall have elapsed from the later of the date the other party
received notice of the recipient's proposed determination to accept, approve,
recommend or enter into an agreement in respect of such Acquisition Proposal,
and the date the other party received a copy of the Acquisition Proposal.

    During such five Business Day period, the other party may, but is not
obligated to, offer to amend the terms of the Merger Agreement and the
Arrangement. The board of directors of the recipient of the Acquisition Proposal
will review any offer by the other party to amend the terms of the Merger
Agreement in good faith in order to determine, in its discretion in the exercise
of its fiduciary duties, whether the other party's offer upon acceptance by the
recipient would result in the Acquisition Proposal no longer being a Superior
Proposal. If the board of directors of the recipient so determines, it will
enter into an amended agreement with the other party reflecting the amended
proposal. If the board of directors of the recipient continues to believe, in
good faith and after consultation with its financial advisors and outside
counsel, that the Acquisition Proposal is nonetheless a Superior Proposal and
therefore rejects the other party's amended proposal, the recipient will pay to
the other party the Break Fee in two equal installments; provided that the
second installment is only payable if (i) the Superior Proposal is consummated
within nine months of termination of the Merger Agreement or (ii) if a binding
agreement which constitutes the Superior Proposal is entered into within such
nine month period and the Superior Proposal is consummated within 12 months of
termination of the Merger Agreement.

    See "The Merger Agreement -- Covenants Regarding Non-Solicitation".

CONDITIONS TO THE TRANSACTION

    The obligations of Uniphase and JDS to complete the Transaction are subject
to the satisfaction or waiver, where permissible, of certain conditions set
forth in the Merger Agreement, including obtaining approval of the Transaction
by JDS Shareholders, Uniphase Stockholders and the Court. See "The Merger
Agreement -- Conditions to Closing".

TERMINATION AND PAYMENT OF BREAK FEES AND EXPENSES

    The Merger Agreement may be terminated by mutual agreement of JDS and
Uniphase at any time prior to the Effective Date. In addition, if the Effective
Date does not occur on or prior to September 30, 1999, the Merger Agreement
automatically terminates, subject to extension by mutual agreement of the
parties thereto. The Merger Agreement automatically terminates upon termination
by Furukawa of its obligations under the Furukawa Support Agreement.

    Uniphase or JDS may terminate the Merger Agreement prior to the Effective
Date and, in certain circumstances, be paid the Break Fee of U.S.$105 million or
U.S.$10 million as an expense reimbursement, if any condition in the respective
party's favor has not been satisfied at or prior to the Effective Date (subject
in some cases to a 30 day cure period), other than as a result of a material
default by the terminating party. In addition, the Merger Agreement may be
terminated by: (i) Uniphase upon the occurrence of any of the JDS Break Fee
Events, subject to the payment by JDS to Uniphase of the Break Fee or (ii) JDS
upon the occurrence of any of the Uniphase Break Fee Events, subject to the
payment by Uniphase to JDS of the Break Fee. Each of JDS or Uniphase may also
terminate the Merger Agreement upon a determination by its respective board of
directors that an Acquisition Proposal is a Superior Proposal, provided that JDS
or Uniphase, as the case may be, is not then in breach or default of any of its
obligations under the Merger Agreement and subject to the payment by JDS or
Uniphase, as the case may be, to the other party of the Break Fee. In the event
of termination of the Merger Agreement based on a determination that a Superior
Proposal has been received by

                                      S-9

either Uniphase or JDS, 50% of the Break Fee is payable by the recipient
immediately upon termination of the Merger Agreement and the remaining 50% of
the Break Fee is payable only (i) if the Superior Proposal is consummated within
nine months of termination of the Merger Agreement or (ii) if a binding
agreement which constitutes the Superior Proposal is entered into within such
nine month period and the Superior Proposal is consummated within 12 months of
termination of the Merger Agreement.

    See "The Merger Agreement -- Termination and Payment of Break Fee and
Expenses".

REGULATORY MATTERS

    Neither Uniphase nor JDS is aware of any material license or regulatory
permits that it holds that might be adversely affected by the Transaction or of
any material regulatory approval or other action by any federal, provincial,
state or foreign government or any administrative or regulatory agency that
would be required to be obtained prior to the Effective Date, except as
described under the headings "The Transaction -- Regulatory Matters" and "The
Transaction -- Court Approval of the Arrangement and Completion of the
Transaction".

ANTICIPATED ACCOUNTING TREATMENT

    It is anticipated that the Transaction will be accounted for by JDS Uniphase
under the purchase method of accounting. See "Risk Factors -- Purchase
Accounting Treatment; Impact of Amortization of Substantial Goodwill and Other
Intangibles on Operating Results" and "The Transaction -- Anticipated Accounting
Treatment".

EFFECTIVE TIME OF THE TRANSACTION

    The Transaction will be completed as soon as practicable after the requisite
JDS Shareholder, Uniphase Stockholder and Court approvals have been obtained and
are final and all other conditions to the Transaction have been satisfied or
waived. See "The Transaction -- Court Approval of the Arrangement and Completion
of the Transaction".

STOCK EXCHANGE LISTINGS

    The TSE has been notified of the proposed Arrangement and the TSE has
conditionally approved the listing of the Class B Non-Voting Preference Shares
and the listing of the Exchangeable Shares, subject to the satisfaction of the
customary requirements of the TSE. The Exchangeable Shares will be listed in
substitution for the JDS Common Shares. There is no current intention to list
the Exchangeable Shares on any stock exchange other than the TSE. The Uniphase
Common Shares, which will, after completion of the Transaction, be the common
shares of JDS Uniphase, are quoted on NASDAQ. Uniphase will apply to NASDAQ to
quote the Uniphase Common Shares issued pursuant to the Arrangement or issuable
from time to time in exchange for the Exchangeable Shares or upon exercise of
the Replacement Options. See "The Transaction -- Stock Exchange Listings".

DIVIDENDS

    Neither Uniphase nor JDS has paid cash or other dividends in the last three
years (other than, in the case of Uniphase, the distribution of Uniphase Rights
described under the heading "Uniphase Capital Stock -- Uniphase Rights
Agreement"). Neither Uniphase nor JDS anticipates the declaration of cash
dividends prior to the Effective Time. It is anticipated that JDS Uniphase will
retain future earnings to finance the development of its business and,
accordingly, will not pay dividends on its outstanding shares in the foreseeable
future. Determinations to pay future dividends and the amount thereof will be
made by the board of directors of JDS Uniphase and will depend on its future
earnings, capital requirements, financial condition and other relevant factors.
See "The Companies after the Transaction -- Dividend Policy".

ELIGIBILITY FOR INVESTMENT

    Provided the Exchangeable Shares are listed on a prescribed stock exchange
in Canada (which currently includes the TSE), the Exchangeable Shares and
Exchangeable Share Rights (i) will be qualified investments under the Canadian
Tax Act for trusts governed by RRSPs, RRIFs and DPSPs and under Tax Proposals
would be qualified investments for trusts governed by RESPs, and (ii) will not
be foreign property under the Canadian

                                      S-10

Tax Act for trusts governed by registered pension plans, RRSPs, RRIFs and DPSPs
or for certain other Persons to whom Part XI of the Canadian Tax Act is
applicable. Provided the Class B Non-Voting Preference Shares are listed on a
prescribed stock exchange in Canada (which currently includes the TSE) the Class
B Non-Voting Preference Shares will be qualified investments and will not be
foreign property under the Canadian Tax Act. The Ancillary Rights will not be
qualified investments under the Canadian Tax Act and will be foreign property.
However, JDS' financial advisor, CIBC World Markets, is of the view that the
fair market value of the Ancillary Rights is nominal. See "The
Transaction -- Eligibility for Investment in Canada".

PROCEDURES FOR EXCHANGE OF SHARE CERTIFICATES

    If the requisite approvals are obtained from JDS Shareholders and Uniphase
Stockholders and the Arrangement is completed, JDS Shareholders will be required
to exchange their share certificates representing JDS Common Shares for share
certificates representing either Uniphase Common Shares or Exchangeable Shares.
JDS Shareholders are advised to review carefully the information under the
heading "Procedures for Exchange of Share Certificates by Shareholders" in the
JDS Circular for a more detailed description of the procedures to be followed by
JDS Shareholders in order to obtain certificates representing the Exchangeable
Shares and the Uniphase Common Shares issuable in the Arrangement. See also
"Transaction Mechanics -- Share Certificates". Uniphase Stockholders will not be
required to exchange their share certificates representing Uniphase Common
Shares as a result of the Transaction.

DISSENT RIGHTS

    JDS Shareholders who properly exercise their Dissent Rights will be entitled
to be paid the fair value of their JDS Common Shares. THE DISSENT PROCEDURES
REQUIRE THAT A JDS SHAREHOLDER WHO WISHES TO DISSENT MUST PROVIDE TO JDS A
DISSENT NOTICE PRIOR TO 5:00 P.M. ON THE BUSINESS DAY PRECEDING THE JDS MEETING.
IT IS IMPORTANT THAT JDS SHAREHOLDERS STRICTLY COMPLY WITH THIS REQUIREMENT
WHICH IS DIFFERENT FROM THE STATUTORY DISSENT PROVISIONS OF THE CBCA WHICH WOULD
PERMIT A DISSENT NOTICE TO BE PROVIDED AT OR PRIOR TO THE JDS MEETING. Uniphase
Stockholders do not have dissenters' appraisal rights under the DGCL in
connection with the Transaction. See "Dissenting Shareholder Rights".

CERTAIN TAX CONSIDERATIONS FOR JDS SHAREHOLDERS

    JDS SHAREHOLDERS SHOULD READ CAREFULLY THE INFORMATION UNDER "TAX
CONSIDERATIONS FOR JDS SHAREHOLDERS" WHICH QUALIFIES THE INFORMATION SET FORTH
BELOW AND SHOULD CONSULT THEIR TAX ADVISORS. NO ADVANCE INCOME TAX RULINGS HAVE
BEEN SOUGHT OR OBTAINED WITH RESPECT TO ANY OF THE TRANSACTIONS DESCRIBED
HEREIN.

CANADA

    The disposition of JDS Common Shares and acquisition of Class B Non-Voting
Preference Shares as a result of the Amalgamation will not result in a taxable
transaction to Canadian Resident JDS Shareholders who hold their JDS Common
Shares as capital property. The exchange by such a JDS Shareholder of all of
their Class B Non-Voting Preference Shares for Exchangeable Shares will
generally not result in a taxable transaction to the JDS Shareholder. The
exchange by such a JDS Shareholder of Class B Non-Voting Preference Shares for
Uniphase Common Shares will generally result in a capital gain (or capital loss)
to the JDS Shareholder.

UNITED STATES

    The exchange by a U.S. Holder of JDS Common Shares for Uniphase Common
Shares pursuant to the Arrangement will be a taxable exchange for United States
federal income tax purposes.

RISK FACTORS

    There are certain risk factors that should be considered by JDS Shareholders
and Uniphase Stockholders in evaluating whether to approve the Transaction. Some
of these risk factors relate directly to the Transaction while others relate to
the business of each of Uniphase and JDS, independent of the Transaction, and
the business of JDS Uniphase. See "Risk Factors".

                                      S-11

CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS

Section 27A of the Securities Act and Section 21E of the Exchange Act. Such
forward-looking statements include: (i) Risk Factors; (ii) The

Discussion and Analysis of Financial Condition and Results of Operations; (iv)
JDS Management's Discussion and Analysis of Financial Condition and Results of
Operations; (v) Business of Uniphase; (vi) Business of JDS; and (vii) The
Companies after the Transaction. The Transaction involves known and unknown
risks, uncertainties and other factors which may cause the actual results and
performance of JDS, Uniphase, JDS Uniphase and the industry to be materially
different from any future results and performance expressed or implied by such
forward-looking statements. Such factors include, among others, general economic
and business conditions, integration of independent businesses, execution by
combined sales and marketing forces, manufacture of Uniphase and JDS products,
technological change, intense industry competition and the ability of JDS,

                                  RISK FACTORS

    The following risk factors should be considered by JDS Shareholders and
Uniphase Stockholders in evaluating whether to approve the proposed Transaction.
Some of these risk factors relate directly to the Transaction while others
relate to the business of each of Uniphase and JDS independent of the
Transaction, as well as the anticipated business of JDS Uniphase. These risk
factors should be considered in conjunction with the other information included
herein.

UNCERTAINTIES ASSOCIATED WITH THE INTEGRATION OF UNIPHASE AND JDS

    The Transaction involves a combination of two companies that have
complementary business operations located principally in the United States,
Canada and Europe. The success of the Transaction will be dependent in large
part on the success of the management of the combined entity in integrating
these operations and the technologies and personnel of the two companies
following the closing. Management of JDS Uniphase will come from the respective
management teams of both of Uniphase and JDS and many members of management will
not have previously worked and communicated with other members of management.
The overall integration of the two businesses can result in unanticipated
operations problems, expenses and liabilities and diversion of management
attention. There can be no assurance that such integration will be successful or
that the combination will not adversely affect the business, financial condition
or operating results of JDS Uniphase.

PURCHASE ACCOUNTING TREATMENT; IMPACT OF AMORTIZATION OF SUBSTANTIAL GOODWILL
  AND OTHER INTANGIBLES ON
  OPERATING RESULTS

    Under U.S. GAAP that will apply to JDS Uniphase after the completion of the
Transaction, the Transaction will be accounted for using the purchase method of
accounting. Under purchase accounting, the estimated market value of Uniphase
Common Shares and the Exchangeable Shares issued in the Arrangement, the fair
value of the Replacement Options and the amount of the direct transaction costs
will be recorded as the cost of acquiring the business of JDS. That cost will be
allocated to the individual assets acquired and liabilities assumed, including
various identifiable intangible assets such as IPRD, acquired technology,
acquired trademarks and tradenames and acquired workforce, based on their
respective fair values. The excess of the purchase cost over the fair value of
the net assets is allocated to goodwill. IPRD, which is currently estimated at
U.S.$177 million, will be expensed immediately. Intangible assets including
goodwill will be amortized over a five year period. As described in the JDS
Uniphase Unaudited Pro Forma Financial Statements, the amount of purchase cost
allocated to goodwill and other intangibles is estimated to be approximately
U.S.$3.2 billion, including the related deferred tax effect. If goodwill and
other intangible assets were amortized in equal quarterly amounts over a five
year period following completion of the Transaction, the accounting charge
attributable to these items would be U.S.$161 million per quarter and U.S.$643
million per fiscal year. As a result, purchase accounting treatment of the
Transaction will result in a net loss for JDS Uniphase in the foreseeable future
which could have a material and adverse effect on the market value of JDS
Uniphase common stock following completion of the Transaction.

EXECUTION BY COMBINED SALES AND MARKETING FORCES

    Uniphase and JDS may experience disruption in sales and marketing as a
result of attempting to integrate their respective sales channels, and may be
unable to smoothly or effectively correct such disruption, or to successfully
execute their sales and marketing objectives, even after the companies'
respective sales and marketing forces have been integrated. In addition, sales
cycles and sales models for the various products may vary significantly from
product to product. Sales personnel not accustomed to the different sales cycles
and approaches required for products newly added to their portfolio may
experience delays and difficulties in selling these newly added products.
Furthermore, it may be difficult to retain key sales personnel during the period
prior to and after the Effective Date of the Transaction. As a result, Uniphase
and JDS may be unable to take full advantage of the combined sales forces'
efforts, and the sales approach and distribution channels of one company may be
ineffective in promoting the products of the other, which may have a material
adverse effect on the business, financial condition or operating results of JDS
Uniphase.

                                      S-24

DILUTION RESULTING FROM THE GRANT OF OPTIONS

    Uniphase has agreed to grant options to acquire 4,110,260 Uniphase Common
Shares at the Effective Time to be allocated to those employees of JDS
designated by the chief executive officer of JDS, with the prior approval of the
compensation committee of the JDS Board of Directors. See "The
Transaction -- Arrangements Respecting Options". The grant of these options,
which will be dilutive to both the former shareholders of JDS and the Uniphase
Stockholders, is intended to cause the employees of JDS to have equivalent stock
option participation in JDS Uniphase following completion of the Transaction as
the employees of Uniphase. These options will have an exercise price equal to
the closing price of Uniphase Common Shares on NASDAQ on the Effective Date and
will vest over the ensuing four year period. Such options may negatively impact
the book value per share and earnings per share of JDS Uniphase on a diluted
basis in future periods.

    It is anticipated that JDS Uniphase will continue, in the ordinary course of
business, to grant options to acquire Uniphase Common Shares from time to time
to new and existing officers, directors and employees of the combined entity
after completion of the Transaction. Any such grants shall be made in the
discretion of the board of directors of JDS Uniphase. The grant of additional
options will cause further dilution in periods following the Effective Time as
holders exercise such options.

MANUFACTURE OF UNIPHASE AND JDS PRODUCTS

    The manufacture of Uniphase and JDS products has involved, and the
manufacture of JDS Uniphase's products will continue to involve, highly complex
and precise processes, requiring production in highly controlled and clean
environments. Changes in these manufacturing processes or those of JDS
Uniphase's suppliers or the inadvertent use of defective or contaminated
materials could significantly reduce manufacturing yields and product
reliability. Certain divisions of Uniphase, including Uniphase Laser Enterprise
AG and Uniphase Netherlands B.V., have in the past experienced and may in the
future experience lower than expected production yields, which could delay
product shipments and impair gross margins. There can be no assurance that any
of JDS Uniphase's manufacturing facilities will maintain acceptable yields in
the future. Because the majority of JDS Uniphase's manufacturing costs will be
relatively fixed, manufacturing yields are critical to results of operations. To
the extent JDS Uniphase does not achieve acceptable manufacturing yields or
experiences product shipment delays, its business, financial condition and
operating results would be materially and adversely affected.

    During the fourth quarter of fiscal 1998, Uniphase commenced construction of
a new laser fabrication facility in the Netherlands for Uniphase Netherlands
B.V., which Uniphase acquired in June 1998. The Uniphase Netherlands B.V.
facility has not achieved acceptable manufacturing yields since the June 1998
acquisition, and there is continuing risk attendant in this new facility and the
manufacturing yields and costs that JDS Uniphase will achieve in the facility.
There can be no assurance that Uniphase Netherlands B.V. will successfully
manufacture laser products in the future at performance or cost levels necessary
to meet JDS Uniphase's customers' needs. In addition, Uniphase Fiber Components
Pty. Limited is establishing a production facility in Sydney, Australia for
fiber Bragg grating products. There can be no assurance that this facility will
manufacture grating products to customers' specifications at the cost and yield
levels required. Each new manufacturing line must go through varying levels of
qualification with JDS Uniphase's customers. This qualification process
determines whether the manufacturing line achieves the customers' minimum
quality, performance and reliability standards. Customers will not purchase any
products (other than a limited number of evaluation units) prior to
qualification of the manufacturing line for the product. Delays in qualification
can cause a product to be dropped from a long-term supply program and result in
significant lost revenue opportunity over the term of that program.

    To the extent JDS Uniphase does not achieve and maintain yields or product
reliability or fails in the timely qualification of new manufacturing lines, its
business, financial condition, operating results and customer relationships
would be adversely affected.

COSTS OF INTEGRATION; TRANSACTION EXPENSES

    Uniphase and JDS estimate they will collectively incur direct transaction
costs of approximately U.S.$12 million associated with the Transaction, which
will be included as a part of the total purchase cost for accounting purposes.
Uniphase and JDS believe the combined entity may incur charges to operations,
which are not currently reasonably estimable, in the quarter in which the
Effective Time occurs or the following quarters, to reflect costs associated
with integrating the two companies. There can be no assurance that the combined

                                      S-25

company will not incur additional material charges in subsequent quarters to
reflect additional costs associated with the Transaction. See "The
Transaction -- Expenses".

SHARES ELIGIBLE FOR FUTURE SALE

    As a result of the Transaction, based on Furukawa's ownership of 37,359,670
JDS Common Shares (and no Uniphase Common Shares) as of the date of this
Supplement, Furukawa, through a subsidiary, will hold, effective upon
consummation of the Transaction, 18,999,260 Exchangeable Shares, representing
approximately 24% of the outstanding Uniphase Common Shares and Exchangeable
Shares taken together. All of the Exchangeable Shares acquired by Furukawa
pursuant to the Arrangement (and Uniphase Common Shares received in exchange
therefor) will be eligible for sale in the U.S. public market subject to the
restrictions of the Securities Act. Further, such shares will be eligible for
sale in the Canadian public market subject to any applicable resale restrictions
under Canadian securities laws. In addition, all of such Exchangeable Shares or
the Uniphase Common Shares received in exchange therefor could be sold by
Furukawa in the public market through the exercise of registration rights
granted pursuant to the Furukawa Registration Rights Agreement (including the
right to have a prospectus relating to such Exchangeable Shares qualified under
Canadian securities laws), including certain "demand" registrations and an
unlimited number of "piggyback" registrations which allow Furukawa to
participate in common equity offerings by JDS Uniphase or Exchangeco.

    Following completion of the Transaction, Koninklijke Philips Electronics
N.V. ("Philips") will hold 3,259,646 Uniphase Common Shares (excluding any
Uniphase Common Shares issuable to Philips upon conversion of the Uniphase
Series A Preferred Shares), representing approximately 4% of the outstanding
Uniphase Common Shares and Exchangeable Shares, taken together. All of the
Uniphase Common Shares held by Philips will be eligible for sale in the U.S.
public market under Rule 144 under the Securities Act commencing June 9, 1999.
Pursuant to a stockholders agreement dated June 9, 1998 between Philips and
Uniphase, Uniphase has agreed to register the Uniphase Common Shares held by
Philips (or received by Philips on conversion of the Uniphase Series A Preferred
shares as discussed below) under United States securities laws in order to
facilitate the sale of such shares.

    Philips holds 100,000 issued and outstanding Uniphase Series A Preferred
Shares which are convertible into Uniphase Common Shares on the earlier of July
1, 2002 or the date on which certain events occur entitling the holders of the
Uniphase Series A Preferred Shares to cause a redemption of such shares. Such
events include a Company Sale, which is deemed to occur on a sale of all or
substantially all the assets of Uniphase, a merger in which Uniphase is not the
surviving corporation and its stockholders own less than 50% of the surviving
entity or any transaction or merger whereby a third party gains control of
Uniphase. The number of Uniphase Common Shares into which each Series A
Preferred Share is convertible is dependent upon unit shipments of certain
products by Uniphase Netherlands during the four-year period ending June 30,
2002 and the market price of Uniphase Common Shares at the time notice of
conversion is delivered to Uniphase. The sale of Uniphase Series A Preferred
Shares is subject to timing and volume limitations pursuant to Rule 144 under
the Securities Act. However, Uniphase has agreed to register the Uniphase Common
Shares issued upon conversion of the Uniphase Series A Preferred Shares as
described above.

    In addition, Uniphase has in the past filed and JDS Uniphase may in the
future file registration statements registering Uniphase Common Shares in
connection with acquisitions or to raise capital for its future needs.

    The sale of Exchangeable Shares or Uniphase Common Shares by Furukawa or
Philips could, due to market saturation, adversely affect the prevailing market
price of the Exchangeable Shares or Uniphase Common Shares and impair Uniphase's
ability to raise capital by issuing equity securities which may have a material
adverse effect on the business, financial condition or operating results of JDS
Uniphase. See "The Transaction -- Interests of Certain Persons in the
Transaction", "The Transaction -- Furukawa Support Agreement" and "The
Transaction -- Resale of Exchangeable Shares and Uniphase Common Shares Received
in the Transaction". In addition, the sale of Uniphase Common Shares pursuant to
Uniphase's current or JDS Uniphase's future registrations of Uniphase Common
Shares could adversely affect the market price of the Exchangeable Shares or the
Uniphase Common Shares.

VARIABILITY AND UNCERTAINTY OF OPERATING RESULTS

    Uniphase and JDS have experienced, and expect JDS Uniphase will experience,
significant fluctuations in quarterly results. Following completion of the
Transaction, fluctuations in quarterly results may cause substantial

                                      S-26

fluctuations in the market price of the Exchangeable Shares and the Uniphase
Common Shares. Factors which have influenced and may continue to influence
operating results in a particular quarter include (i) the timing of the receipt
of product orders from a limited number of major customers, (ii) the ability to
manufacture technically advanced products with satisfactory yields on a timely
basis, (iii) product mix, (iv) competitive pricing pressures, (v) the relative
proportions of domestic and international sales, (vi) costs associated with the
acquisition or disposition of businesses, (vii) the ability to design,
manufacture and ship products in a timely and cost effective manner, (viii) the
timing differences between when expenses are incurred to increase marketing and
sales capabilities and when corresponding benefits are realized, if any, (ix)
the announcement and introduction of new products by JDS Uniphase and by its
competitors, (x) expenses associated with any intellectual property litigation,
and (xi) the continuous supply or availability of critical materials from
strategic or sole-source suppliers.

    In addition, sales often reflect orders shipped in the same quarter in which
they are received. Also, customers may cancel or reschedule shipments, and
production difficulties could delay shipments. Uniphase frequently ships more
CATV products in the third month of each quarter than in each of the first two
months of the quarter and shipments in the third month generally are higher at
the end of the month. Uniphase and JDS have sold, and JDS Uniphase will continue
to sell, telecommunications equipment products to OEMs who typically order in
large quantities and therefore the timing of such sales may significantly affect
quarterly results. The timing of such OEM sales can be affected by factors
beyond JDS Uniphase's control, such as demand for the OEMs' products and
manufacturing risks experienced by OEMs. In this regard, Uniphase and JDS have
experienced rescheduling of orders by customers in each of its markets and JDS
Uniphase will likely experience similar rescheduling in the future. As a result
of all of these factors, JDS Uniphase's results from operations may vary
significantly from quarter to quarter and management may not be able to
forecast, with certainty, any quarterly results. Future acquisitions or
dispositions of businesses, products or technologies by JDS Uniphase may result
in substantial charges or other expenses that may cause fluctuations in its
quarterly operating results which could materially and adversely affect the
business, financial condition or operating results of JDS Uniphase.

    The acquisition or disposition of other businesses, products or technologies
may also affect JDS Uniphase's operating results in any particular quarter. For
example, in the second and fourth quarters of fiscal 1998, Uniphase incurred
charges of U.S.$6.6 million and U.S.$33.7 million, respectively, for acquired
IPRD in connection with the acquisition of Uniphase Fiber Components Pty.
Limited and Uniphase Netherlands B.V. In the third quarter of fiscal 1997,
Uniphase incurred charges of U.S.$33.3 million for acquired IPRD in connection
with the acquisition of Uniphase Laser Enterprise AG. In addition, Uniphase
incurred other charges in connection with acquisitions and dispositions
completed in fiscal 1999, 1998 and 1997. Furthermore, JDS Uniphase expects to
incur a charge currently estimated at U.S.$177 million for IPRD in connection
with the Transaction. Future acquisitions or dispositions of businesses,
products or technologies by JDS Uniphase may result in a reorganization of its
operations, substantial charges or other expenses that may cause fluctuations in
JDS Uniphase's quarterly operating results and its cash flows, and may cause the
business, financial condition and operating results of JDS Uniphase to be
materially and adversely affected.

MARKET PRICE FLUCTUATIONS

    The market price of Uniphase Common Shares or JDS Common Shares could each
fluctuate significantly in response to various factors and events, including the
differences between JDS' and Uniphase's actual financial or operating results
and those expected by investors and analysts, changes in analysts' projections
or recommendations, changes in general economic or market conditions and broad
market fluctuations. As a result of such fluctuations, the market value of the
Uniphase Common Shares that holders of JDS Common Shares will receive pursuant
to the Transaction or upon exchange of the Exchangeable Shares may increase or
decrease. Because historical market prices are not indicative of future market
prices, JDS Shareholders should obtain current market quotations for the JDS
Common Shares and the Uniphase Common Shares. There can be no assurance that the
Uniphase Common Shares or Exchangeable Shares that the holders of JDS Common
Shares receive after consummation of the Transaction will equal or exceed the
market value of the JDS Common Shares held by such shareholders prior to the
Effective Time.

MARKET PRICE OF EXCHANGEABLE SHARES AND UNIPHASE COMMON SHARES

    Although Uniphase and JDS anticipate that the market price of the
Exchangeable Shares on the TSE and the market price of the Uniphase Common
Shares on NASDAQ will reflect essentially equivalent values, there

                                      S-27

can be no assurance that the market price of Uniphase Common Shares will be
identical, or even similar, to the market price of the Exchangeable Shares. The
TSE has conditionally approved the listing of the Exchangeable Shares on the
Effective Date subject to fulfilling all of the requirements of the TSE. The
Uniphase Common Shares are listed on NASDAQ. Uniphase has agreed that the
Uniphase Common Shares issued pursuant to the Transaction and issuable from time
to time in exchange for the Exchangeable Shares will be listed on NASDAQ. There
is no current intention to list the Exchangeable Shares or the Uniphase Common
Shares on any other stock exchange in Canada or the United States. Consequently,
the price at which the Exchangeable Shares will trade will be based upon the
market for such shares on the TSE and the price at which the Uniphase Common
Shares will trade will be based upon the market for such shares on NASDAQ.

RISKS FROM CUSTOMER CONCENTRATION

    Historically, orders from a relatively limited number of OEM customers
accounted for a substantial portion of Uniphase's and JDS' respective net sales
from telecommunications products. In the telecommunications markets, customers
evaluate products and competitive products for deployment in large
telecommunications systems that they are installing. The failure to be selected
by a customer for particular system projects, or the failure of a key customer
to be selected as the primary supplier for an overall system installation, could
have a significant impact on JDS Uniphase's business, operating results and
financial condition. Further, sales to any single customer may vary
significantly from quarter to quarter. Such fluctuations could have a material
adverse effect on JDS Uniphase's business, operating results and financial
condition. Uniphase and JDS expect that, for the foreseeable future, JDS
Uniphase's sales to a limited number of customers will continue to account for a
high percentage of its net sales. There can be no assurance that current
customers will continue to place orders or that JDS Uniphase will obtain new
orders from new customers.

    On a pro forma basis, one telecommunications customer would have accounted
for approximately 12% of JDS Uniphase's net sales for the year ended June 30,
1998. On a pro forma basis, no other customer of JDS Uniphase would have
represented 10% or more of total sales of JDS Uniphase. The loss or delay of
orders from this customer or other OEM customers could have a material adverse
effect on JDS Uniphase's business, financial condition and operating results.

INTENSE INDUSTRY COMPETITION

    The telecommunications and laser subsystems industries in which Uniphase and
JDS have each sold their products, and in which JDS Uniphase will sell its
products, are highly competitive. In each of these industries JDS Uniphase will
face intense competition from established competitors. Many of these competitors
have substantially greater financial, engineering, manufacturing, marketing,
service and support resources than JDS Uniphase. Uniphase and JDS have each
competed, and JDS Uniphase will compete, with many companies in the
telecommunications industry that have substantially greater resources, greater
name recognition, manufacturing expertise and capability and longer standing
customer relationships than JDS Uniphase. To remain competitive, Uniphase and
JDS believe JDS Uniphase must maintain a substantial investment in research and
development, marketing, and customer service and support. There can be no
assurance that JDS Uniphase will compete successfully in the laser or
telecommunications industries in the future, that JDS Uniphase will have
sufficient resources to continue to make such investments, that JDS Uniphase
will make the technological advances necessary to maintain its competitive
position, that its products will receive market acceptance or that competitive
pressures will not result in lower prices, loss of market share or reduced gross
margins for JDS Uniphase products. In addition, technological changes or
development efforts by JDS Uniphase's competitors may render JDS Uniphase's
products or technologies obsolete or uncompetitive, which could have a material
adverse effect on JDS Uniphase's business, financial condition and operating
results.

ATTRACTING AND RETAINING KEY PERSONNEL

    JDS Uniphase's future business, financial condition and operating results
depend, in part, on its ability to attract and retain certain key personnel. In
particular, JDS Uniphase's research and development efforts depend on hiring and
retaining qualified engineers and scientists. Competition for highly skilled
engineers and other technical personnel is extremely intense, and Uniphase and
JDS have each experienced, and expect JDS Uniphase to continue to experience,
difficulty in identifying and hiring such qualified technical personnel in many
areas of business. There can be no assurance that JDS Uniphase will be able to
hire and retain such personnel at compensation levels consistent with Uniphase's
or JDS' existing compensation and salary structure.

                                      S-28

JDS Uniphase's future business, financial condition and operating results also
depend on the continued contributions of certain Uniphase and JDS executive
officers and other key management and technical personnel, only certain of whom
either has an employment agreement with Uniphase or JDS or will have an
employment and/or a retention agreement with JDS Uniphase and each of whom would
be difficult to replace. JDS Uniphase will not maintain key person life
insurance for any of its executive officers. However, the loss of the services
of one or more of Uniphase's or JDS' current executive officers or key personnel
or the inability to continue to attract qualified personnel could delay product
development cycles or otherwise have a material adverse effect on JDS Uniphase's
business, financial condition and operating results.

MANAGEMENT OF GROWTH; ACQUISITION RISKS

    Uniphase has historically achieved its growth through a combination of
acquisitions and internally developed new products, and Uniphase and JDS expect
JDS Uniphase to continue to pursue acquisitions of other companies, technologies
and complementary product lines as part of its strategy to sustain growth. It is
also expected that JDS Uniphase will continue developing new solid state lasers,
components and other products for OEM customers and attempting to further
penetrate the telecommunications and CATV markets through these new products.
However, there can be no assurance that those courses of action will succeed and
if they do not, the business, financial condition and operating results of JDS
Uniphase could be materially and adversely affected.

    In March 1997, Uniphase acquired Uniphase Laser Enterprise AG and in June
1998, Uniphase acquired Uniphase Netherlands B.V. In both acquisitions, Uniphase
acquired businesses that had previously been engaged primarily in research and
development and that needed to make the transition from research activity to a
commercial business with sales and profit levels that are consistent with
Uniphase's overall financial goals. This transition has not yet been completed
at Uniphase Netherlands B.V., which continues to operate at higher expense
levels and lower gross margins than those required to meet profitability goals.
In addition, in August 1998, Uniphase acquired certain assets of Chassis
Engineering, Inc., and in November 1998 acquired Broadband Communications
Products, Inc. (now Uniphase Broadband Products, Inc.). The success of each of
these acquisitions will depend upon JDS Uniphase's ability to manufacture and
sell high power lasers and other components, modules and subsystems used in
wavelength divisional multiplexing applications and continued demand for these
acquired products by telecommunications and CATV customers. There can be no
assurance that these acquired businesses will achieve profitability goals in the
near future, if at all.

    JDS Uniphase's ability to manage its growth effectively through acquisitions
depends upon the integration into JDS Uniphase of the acquired entities'
operations, products and personnel, the retention of key personnel of the
acquired entities and the expansion of JDS Uniphase's financial and management
controls and reporting systems and procedures. There can be no assurance that
JDS Uniphase will successfully manufacture and sell these products or
successfully manage such growth, and failure to do so could have a material
adverse effect on JDS Uniphase's business, financial condition and operating
results.

    Since 1997, when Uniphase acquired Uniphase Laser Enterprise AG, Uniphase
has increased its marketing, customer support and administrative functions to
support an increased level of operations primarily from sales of its
telecommunications products. There can be no assurance that JDS Uniphase will
succeed in supporting or expanding this infrastructure or in increasing the
level of sales and operations through JDS Uniphase's new products. In 1996,
Uniphase commenced operations in Pennsylvania at Uniphase Telecommunications
Products, Inc. to penetrate the CATV markets, and, in 1998, at Uniphase Network
Components to develop and market a line of complementary optical components for
their respective telecommunications customers. In each case, Uniphase hired
development, manufacturing and other staff in anticipation of developing and
selling new products. There can be no assurance that JDS Uniphase's operations
will achieve levels sufficient to justify the increased expense levels
associated with these new businesses.

DECLINE IN AVERAGE SELLING PRICES

    The fiberoptic component segment of the telecommunications industry is
generally characterized by declining average selling prices resulting from such
factors as increased competition and greater unit volumes as telecommunication
service providers continue to deploy fiberoptic networks. JDS and Uniphase have
in the past and JDS Uniphase may in the future experience substantial period to
period fluctuations in average selling prices. JDS and Uniphase anticipate that
average selling prices will decrease in the future in response to product
introductions by competitors and JDS Uniphase or to other factors, including
price pressures from significant

                                      S-29

customers. Therefore, JDS Uniphase must continue to (i) develop and introduce on
a timely basis new products that incorporate features that can be sold at higher
average selling prices and (ii) reduce its manufacturing costs. Failure to
achieve any or all of the foregoing could cause JDS Uniphase's net sales and
gross margins to decline, which may have a material adverse effect on JDS
Uniphase's business, financial condition and operating results.

TECHNOLOGICAL CHANGE

    Technology in the fiberoptics industry continues to advance at a rapid pace
which requires the timely introduction of new products and technologies. In most
of Uniphase's and JDS' product areas, Uniphase and JDS and current and potential
competitors are working to develop new technologies or improvements and
modifications to existing technologies. There can be no assurance that markets
will develop for new products or continue to develop for existing products, or
that the products of JDS Uniphase will be competitive with other technologies or
products that may be developed by others. Failure to introduce new products and
technologies could have a material adverse effect on JDS Uniphase's business,
financial condition and operating results.

COLLECTIVE BARGAINING AGREEMENTS

    JDS and Uniphase employees who are employed at manufacturing facilities
located in North America are not bound by or party to any collective bargaining
agreements with JDS or Uniphase. There can be no assurance that any such
employees will not be bound by or party to any collective bargaining agreements
with JDS, Uniphase and JDS Uniphase in the future. Certain employees of JDS and
Uniphase outside of North America, particularly in the Netherlands and Germany,
are subject to collective bargaining agreements. If, in the future, any such
employees become bound by or party to any collective bargaining agreements, then
JDS Uniphase's related labour costs and its flexibility with respect to managing
its business operations involving such employees may be materially adversely
affected.

YEAR 2000

    Uniphase and JDS are aware of the risks associated with the operation of
information technology ("IT") and non-information technology ("non-IT") systems
as the millennium (Year 2000) approaches. The "Year 2000" problem is pervasive
and complex, and may affect many IT and non-IT systems. The Year 2000 problem
results from the rollover of the two digit year value from "99" to "00." Systems
that do not properly recognize such date-sensitive information could generate
erroneous data or fail. In addition to relying on their own systems, both JDS
and Uniphase rely on external systems of their respective customers, suppliers,
creditors, financial organizations, utilities providers and government entities,
both domestic and international (collectively, "Third Parties"). Consequently,
JDS Uniphase could be affected by disruptions in the operations of Third Parties
with which JDS Uniphase interacts. Furthermore, as customers expend resources to
correct their own IT and non-IT systems, they may reduce the frequency and
volume of purchases of JDS Uniphase products.

    Uniphase and JDS are each using both internal and external resources to
assess their state of readiness (including the readiness of Third Parties with
which each now interacts and JDS Uniphase will interact) concerning the Year
2000 problem, costs to correct material Year 2000 problems related to internal
IT and non-IT systems, known risks related to any failure to correct any
identified Year 2000 problems and the contingency plan, if any, that JDS
Uniphase should adopt should any identified Year 2000 problems not be corrected.

    To date, Uniphase and JDS have each incurred costs not exceeding U.S.$1
million and Cdn.$1.2 million, respectively, to upgrade their IT and non-IT
systems to, among other things, make such systems Year 2000 compliant. Uniphase
and JDS continue to evaluate the estimated costs associated with the efforts to
prepare for Year 2000 based on actual experience. While the efforts will involve
additional costs, Uniphase and JDS each believe, based on (i) available
information, (ii) amounts spent to date and (iii) the fact that JDS' and
Uniphase's IT and non-IT systems depend on third-party software which, to JDS'
and Uniphase's belief, has been or is being updated to address the Year 2000
problem, that JDS Uniphase will manage its total Year 2000 transition without
any material adverse effect on JDS Uniphase's business, financial condition,
operating results, products or financial prospects. The actual outcomes and
results could be affected by future factors including, but not limited to, the
continued availability of skilled personnel, cost control, the ability to locate
and remediate software code problems, critical suppliers and subcontractors
meeting their Year 2000 compliance commitments and timely actions by customers.

                                      S-30

    Uniphase and JDS are each working with their respective system suppliers and
believe that certain of these systems are currently not Year 2000 compliant.
Uniphase and JDS have targeted September 30, 1999 as the date by which these
systems shall be Year 2000 compliant. In any event, it is anticipated that such
systems will be corrected for the Year 2000 problem prior to December 31, 1999.
Uniphase and JDS are each working with Third Parties to identify any Year 2000
problems affecting such Third Parties that could have a material adverse affect
on the business, financial condition or operating results of JDS Uniphase.
However, it would be impracticable for Uniphase or JDS to attempt to address all
potential Year 2000 problems of Third Parties that have been or may in the
future be identified. Specifically, Year 2000 problems have arisen or may arise
regarding the IT and non-IT systems of Third Parties having widespread national
and international interactions with persons and entities generally (for example,
certain IT and non-IT systems of governmental agencies, utilities and
information and financial networks) that, if uncorrected, could have a material
adverse effect on JDS Uniphase's business, financial condition or operating
results. Uniphase and JDS are each still assessing the effect the Year 2000
problem will have on their respective significant suppliers and, at this time,
cannot determine such effect. However, JDS and Uniphase have identified
alternative suppliers and, in the event that any significant supplier suffers
unresolved material Year 2000 problems, JDS and Uniphase each believe that JDS
Uniphase would only experience short term disruptions in supply, not exceeding
90 days, while such supplier is replaced. In addition, JDS' current practice is
to carry a strategic inventory of sole source materials, which can be drawn on
in the event of any short-term supply disruptions.

CONFLICTING PATENTS AND INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES; POTENTIAL
  INFRINGEMENT CLAIMS

    The laser and telecommunications markets in which Uniphase and JDS have sold
their products, and in which JDS Uniphase will sell its products, experience
frequent litigation regarding patent and other intellectual property rights.
Numerous patents in these markets are held by others, including academic
institutions and Uniphase's and JDS' competitors. Any patent disputes could
inhibit JDS Uniphase's development of new products for such markets. While in
the past licenses generally have been available to Uniphase and JDS where
third-party technology was necessary or useful for the development or production
of their respective products, there can be no assurance that licenses to
third-party technology will be available to JDS Uniphase on commercially
reasonable terms, if at all. Generally, a license, if granted, will require
payments by JDS Uniphase of up-front fees, ongoing royalties or a combination
thereof. Such royalty or other terms could have a significant adverse impact on
JDS Uniphase's operating results. Uniphase and JDS are each a licensee of a
number of third party technologies and intellectual property rights and each is
required to pay royalties to these third party licensors on certain of their
respective telecommunications products and solid state lasers. JDS Uniphase will
be required to make such royalty payments in the future. During fiscal 1998,
1997 and 1996, Uniphase expensed U.S.$2.0 million, U.S.$1.4 million and U.S.$1.3
million, respectively, in license and royalty fees primarily in connection with
Uniphase's gas laser subsystems. During fiscal 1998, 1997, and 1996, JDS license
and royalty fees were insignificant.

    In addition, third parties may in the future assert claims against JDS
Uniphase concerning Uniphase's or JDS' existing products or with respect to JDS
Uniphase's future products under development which could have a material adverse
effect on the business, financial condition and operating results of JDS
Uniphase. Any litigation undertaken to determine the validity of any third-party
claims could result in significant expense to JDS Uniphase and divert the
efforts of JDS Uniphase's technical and management personnel, whether or not JDS
Uniphase is successful in such litigation. If JDS Uniphase is unsuccessful in
any such litigation, JDS Uniphase could be required to expend significant
resources to develop non-infringing technology or to obtain licenses to the
technology which is the subject of the litigation. There can be no assurance
that JDS Uniphase would be successful in such development or that any such
licenses would be available to JDS Uniphase on commercially reasonable terms, if
at all. Without such licenses, JDS Uniphase could be enjoined from future sales
of the infringing product or products.

EURO CURRENCY

    On January 1, 1999, several member countries of the European Union
established fixed conversion rates between their existing sovereign currencies
and adopted the Euro as their new common legal currency. From then on, the Euro
has traded and will trade on currency exchanges and the sovereign or "legacy"
currencies will remain legal tender in the participating countries for a
transition period between January 1, 1999 and January 1,

                                      S-31

2002. During the transition period, noncash payments can be made in the Euro,
and parties can elect to pay for goods and services and transact business using
either the Euro or a legacy currency. Between January 1, 2002 and July 1, 2002
the participating countries will introduce Euro notes and coins and withdraw all
legacy currencies, which will no longer be available. The Euro conversion may
affect cross-border competition by creating cross-border price transparency.
Uniphase and JDS are assessing their pricing/marketing strategy in order to
ensure that JDS Uniphase remains competitive in a broader European market.
Uniphase and JDS are also assessing their information technology systems to
allow for transactions to take place in both the legacy currencies and the Euro
and the eventual elimination of the legacy currencies, and reviewing whether
certain existing contracts will need to be modified. JDS Uniphase's currency
risk and risk management for operations in participating countries may be
reduced as the legacy currencies are converted to the Euro. Final accounting,
tax and governmental legal and regulatory guidance are not yet available. JDS
Uniphase will continue to evaluate issues involving the introduction of the
Euro. Based on current information and Uniphase's and JDS' current assessment,
although there can be no assurance, neither Uniphase nor JDS expects that the
Euro conversion will have a material adverse effect on JDS Uniphase's business,
financial condition or operating results.

FINANCIAL MARKET RISKS

    Each of Uniphase and JDS experiences financial market risks, including
changes in interest rates, foreign currency exchange rates and marketable equity
security prices. Both companies utilize derivative financial instruments to
mitigate these risks. Neither Uniphase nor JDS uses derivative financial
instruments for speculative or trading purposes. The primary objective of their
investment activities is to preserve principal while at the same time maximizing
yields without significantly increasing risk. To achieve this objective, a
majority of Uniphase's marketable investments are floating rate and municipal
bonds, auction instruments and money market instruments denominated in U.S.
dollars. A substantial portion of Uniphase's sales, expenditures and capital
purchasing activities are transacted in U.S. dollars and certain European
currencies. To protect against reductions in value and the volatility of future
cash flows caused by changes in foreign exchange rates, Uniphase hedges with
currency forward contracts. Uniphase's hedging programs reduce, but do not
always entirely eliminate the impact of foreign currency exchange rate
movements. Actual effects on Uniphase's financial position may differ
materially. JDS places its cash equivalents and short-term investments with
Canadian governmental agencies and high quality Canadian financial institutions.
JDS uses forward exchange contracts to manage its foreign currency exposures.
The majority of JDS' sales are in U.S. dollars and a portion of JDS' expenses
are in U.S. dollars and Japanese yen. The use by JDS of forward exchange
contracts reduces but does not eliminate the impact of foreign currency exchange
rate fluctuations. It is anticipated that JDS Uniphase will be subject to the
same financial market risks as Uniphase and JDS and will continue to employ
similar strategies as Uniphase and JDS to mitigate these risks. In the event
that such strategies are not successful, the business, financial condition and
operating results of JDS Uniphase could be materially and adversely affected.

TAX CONSEQUENCES OF EXCHANGE

    The Transaction has been structured to provide the opportunity for a tax
deferral for Canadian tax purposes for Canadian Residents who receive
Exchangeable Shares pursuant to the Arrangement. However, Canadian Residents
will generally only be able to obtain Canadian tax deferral for as long as they
hold the Exchangeable Shares, and will generally recognize a taxable dividend
and/or a gain or loss upon the exchange of their Exchangeable Shares for
Uniphase Common Shares. Redemption of the Exchangeable Shares for Uniphase
Common Shares may occur at any time after the Effective Date if a Redemption
Date occurs. Because of the existence of the Call Rights, the Exchange Right and
the Automatic Exchange Right, a holder of Exchangeable Shares cannot control
whether such holder will receive Uniphase Common Shares by way of redemption of
the Exchangeable Shares by Exchangeco or by way of purchase of the Exchangeable
Shares by Uniphase or Uniphase Nova Scotia. The Canadian federal income tax
consequences of a redemption differ from those of a purchase. See "Description
of Exchangeable Shares -- Redemption", "Description of Exchangeable Shares --
Early Redemption", "Tax Considerations for JDS Shareholders -- Canadian Federal
Income Tax Considerations for JDS Shareholders".

LACK OF PUBLIC MARKET FOR UNIPHASE COMMON SHARES IN CANADA

    The Uniphase Common Shares are not listed on any Canadian stock exchange.
Uniphase and JDS do not initially intend to list the outstanding Uniphase Common
Shares or the Uniphase Common Shares to be issued pursuant to the Arrangement on
the TSE or any other Canadian stock exchange.

                                      S-32

                                THE TRANSACTION

GENERAL

    The Uniphase Board of Directors and the JDS Board of Directors each have
approved the Merger Agreement. The Merger Agreement provides that subsidiaries
of Uniphase will acquire all of the JDS Common Shares, subject to, among other
things: (i) approval of the Uniphase Transaction Proposal by the Uniphase
Stockholders; (ii) approval of the Arrangement by the JDS Shareholders; and
(iii) approval of the Arrangement by the Court. As a consequence of the
Arrangement, JDS will become an indirect wholly-owned subsidiary of Uniphase.
Pursuant to the Amalgamation, the holders of JDS Common Shares (other than those
JDS Shareholders who properly exercise their Dissent Rights) will initially
receive 0.50855 of a Class B Non-Voting Preference Share for each JDS Common
Share. Immediately thereafter, the Class B Non-Voting Preference Shares will, at
the option of the holders thereof, be exchanged for either one Uniphase Common
Share or one Exchangeable Share for each Class B Non-Voting Preference Share;
provided that any holder of Class B Non-Voting Preference Shares who is not a
Canadian Resident will not be entitled to receive Exchangeable Shares and will
be required to receive Uniphase Common Shares and provided that a holder must
make the same election in respect of all their Class B Non-Voting Preference
Shares or the election will not be effective. Any holder of Class B Non-Voting
Preference Shares who does not make an effective election will receive one
Exchangeable Share for each Class B Non-Voting Preference Share, other than
holders of Class B Non-Voting Preference Shares who are not Canadian Residents
who will receive one Uniphase Common Share for each Class B Non-Voting
Preference Share. See "Transaction Mechanics", "Description of Exchangeable
Shares" and "Exchangeco Share Capital -- Class B Non-Voting Preference Shares".

    JDS Shareholders who own JDS Common Shares indirectly through a Holding
Company have the option of including such Holding Company in the Amalgamation
and receiving consideration identical to that which would have been received by
the Holding Company in the Arrangement if such Holding Company was not included
in the Amalgamation. See "Transaction Mechanics -- Holding Company Alternative".

    Uniphase and its affiliates do not currently own any JDS Common Shares and
are prohibited under the Merger Agreement from acquiring any JDS Common Shares
prior to the Effective Time without the prior approval of JDS. Based on the
number of JDS Common Shares outstanding on January 27, 1999, immediately
following completion of the Transaction, the former holders of JDS Common Shares
will hold an aggregate of approximately 39.7 million Exchangeable Shares and
Uniphase Common Shares. Assuming all JDS Common Shares are exchanged for
Uniphase Common Shares and based upon the number of Uniphase Common Shares and
JDS Common Shares outstanding as of January 27, 1999, immediately following
completion of the Transaction existing JDS Shareholders would hold approximately
50% of the outstanding Uniphase Common Shares.

    The Exchangeable Shares will be issued by Exchangeco and their holders will
be entitled (i) to dividend and other rights that are, as nearly as practicable,
economically equivalent to those of the Uniphase Common Shares and (ii), through
a voting trust, to vote at meetings of Uniphase Stockholders. See "Description
of Exchangeable Shares -- Voting, Dividend and Liquidation Rights".

    Holders of Exchangeable Shares will have the right at any time to exchange
each Exchangeable Share for one Uniphase Common Share. At any time on or after
March 31, 2014 (subject to acceleration if there are fewer than 992,372
Exchangeable Shares outstanding, which number may be adjusted pursuant to the
Exchangeable Share Provisions or upon the occurrence of certain events, in each
case subject to the provisions of the Furukawa Support Agreement), Exchangeco
will have the right, but not the obligation, to redeem all outstanding
Exchangeable Shares for an equal number of Uniphase Common Shares. See
"Description of Exchangeable Shares -- Redemption" and "Description of
Exchangeable Shares -- Early Redemption".

    JDS Shareholders who properly exercise their Dissent Rights will be entitled
to be paid the fair value of their JDS Common Shares. Dissenters' appraisal
rights under the DGCL are not available to Uniphase Stockholders in connection
with the Transaction. See "Dissenting Shareholder Rights".

    Pursuant to the Uniphase Rights Agreement, each Uniphase Common Share is
accompanied by and trades with one Uniphase Right. Each Exchangeable Share will
similarly be accompanied by and trade with one Exchangeable Share Right that
will entitle its holder to acquire additional Exchangeable Shares at the same

                                      S-33

price and in the same amounts and circumstances in which holders of Uniphase
Rights are entitled to acquire Uniphase stock. See "Description of Exchangeable
Shares -- Exchangeable Share Rights" and "Uniphase Capital Stock -- Uniphase
Rights Agreement".

BACKGROUND

    The provisions of the Merger Agreement are the result of arm's length
negotiations conducted among representatives of JDS and Uniphase and their legal
and financial advisors. The following is a summary of the meetings, negotiations
and discussions between the parties that preceded execution of the Merger
Agreement.

    Commencing in June 1998, Kevin Kalkhoven, Chief Executive Officer of
Uniphase, and Jozef Straus, Chief Executive Officer of JDS, held preliminary
discussions concerning the potential advantages of a combination of Uniphase and
JDS. These discussions continued and resulted in meetings in July 1998 in JDS'
Nepean, Ontario headquarters between members of senior management of both
companies as to the advisability of pursuing a combination of the two companies.
As a result of these discussions, JDS and Uniphase executed a non-disclosure
agreement on July 27, 1998.

    Commencing in June 1998, CIBC World Markets provided advice to JDS in
connection with the proposed transaction. On November 23, 1998, JDS formally
engaged CIBC World Markets to act as its financial advisor in connection with
the proposed transaction. Commencing in August 1998, BT Alex. Brown advised
Uniphase regarding the proposed combination with JDS. On November 10, 1998,
Uniphase formally engaged BT Alex. Brown as its financial advisor in connection
with the proposed transaction.

    During August and September 1998, preliminary due diligence discussions
continued between senior management of JDS and Uniphase regarding a possible
combination of the two companies. During this period, the parties discussed
possible management structures for the combined entity and the advantages and
general terms of a potential transaction between JDS and Uniphase.

    At its meeting on August 17, 1998, the Uniphase Board of Directors engaged
in a lengthy discussion as to the potential merits of a combination with JDS.
The Uniphase Board of Directors authorized Uniphase senior management to
continue to pursue these discussions with JDS.

    On September 15, 1998, Mr. Kalkhoven, Anthony Muller, Chief Financial
Officer of Uniphase, and Michael Phillips, Senior Vice President, Business
Development and General Counsel of Uniphase, met with Dr. Straus and Zita Cobb,
Chief Financial Officer of JDS, at a trade conference in California to further
discuss the proposed transaction between JDS and Uniphase. On the basis of these
meetings, the parties determined to continue their discussions and to develop
more specific terms for the proposed combination.

    The Uniphase Board of Directors reviewed the proposed merger and the results
of due diligence by Uniphase management regarding JDS at its October 17, 1998
meeting and considered input from BT Alex. Brown.

    At its meeting on October 28, 1998, the JDS Board of Directors discussed the
general terms and potential merits of a combination with Uniphase and considered
input from CIBC World Markets.

    Dr. Straus visited Uniphase's Zurich facility on November 8, 1998 and
Uniphase's Eindhoven facility on November 9, 1998. The purpose of these visits
was to meet with members of senior management of Uniphase and to discuss
integration and employee issues which would affect the combined entity. On
November 13, 1998, Mr. Phillips, Catherine Lego, a member of the Uniphase Board
of Directors, and representatives of BT Alex. Brown visited JDS' Nepean, Ontario
facility to conduct due diligence with respect to JDS. On November 13, 1998, JDS
and Uniphase executed a second and broader mutual non-disclosure agreement.

    The Uniphase Board of Directors reviewed the proposed merger again at its
November 20, 1998 meeting. Representatives of BT Alex. Brown participated in
this meeting in their capacity as financial advisors to Uniphase in connection
with the Transaction.

    During December 1998, the parties exchanged preliminary drafts of definitive
agreements. On December 10, 1998, Joseph Ip, Senior Vice President, Optical
Networking Products & Technologies of JDS, and Jozef Finak, Vice President,
Photonics Technologies of JDS, visited Uniphase's Zurich and Eindhoven
facilities

                                      S-34

to conduct due diligence with respect to Uniphase. On December 14 and December
15, 1998, Ms. Cobb, Konstantin Kotzeff, Vice-President, Legal Affairs of JDS,
and Leo Lefebvre, Vice-President, Finance of JDS, and representatives of CIBC
World Markets travelled to Uniphase's offices in San Jose, California. The
purpose of this visit was to perform further due diligence and to meet with
members of senior management of Uniphase and representatives of BT Alex. Brown
to discuss the terms of the proposed combination in further detail and to
discuss employee issues which would affect the combined entity.

    On January 7 and January 8, 1999, Mr. Kalkhoven, Mr. Phillips and Frederick
Leonberger, Uniphase's Senior Vice President and Chief Technology Officer,
visited with senior management of JDS at JDS' Nepean facility to perform further
due diligence with respect to JDS and to discuss the management structure of the
combined entity and the integration of the merged businesses. Present at these
meetings for JDS were Dr. Straus, Ms. Cobb, Mr. Ip and Mr. Kotzeff.

    On January 11 and 12, 1999, Mr. Muller and Kerry DeHority, Vice President
and Controller of Uniphase, performed financial due diligence and visited with
Mr. Lefebvre at an offsite location in Ottawa, Canada.

    At its meeting on January 13, 1999, the JDS Board of Directors reviewed the
proposed merger and engaged in a lengthy discussion regarding the terms and
potential merits of a combination with Uniphase. Representatives of CIBC World
Markets were present and participated at this meeting.

    On January 14 and January 15, 1999, Mr. Phillips, Mr. Kotzeff and their
respective legal counsel and financial advisors met in Toronto, Ontario with
representatives of Furukawa and Furukawa's legal advisors. Certain terms of the
Furukawa Support Agreement and the Furukawa Registration Rights Agreement were
discussed among the parties.

    On January 14, 1999, Wilson Sibbett, Martin Kaplan, Robert Fink and Willem
Haverkamp, directors of Uniphase, and Mr. Phillips met in Toronto with Koichi
Abe and Bruce Day, directors of JDS, Ms. Cobb and Mr. Kotzeff to continue their
respective due diligence and to continue discussions regarding the proposed
merger. On the following day, the four Uniphase directors visited JDS'
facilities in Nepean, Ontario for further due diligence with respect to JDS.

    The Uniphase Board of Directors met on January 16, 1999 and discussed the
status of negotiations and due diligence with JDS. Representatives of BT Alex.
Brown participated in this meeting and provided data to the Uniphase Board of
Directors as to the prices and other terms of comparable transactions. The
Uniphase Board of Directors again authorized the Uniphase officers to continue
their discussions with JDS.

    On January 19 and January 20, 1999, senior members of management of each of
Uniphase and JDS met outside of Toronto, Ontario to perform further reciprocal
due diligence. These meetings related primarily to an indepth exchange of
information regarding each party's products, strategies, customers, accounting
policies and information systems. Representatives of each of BT Alex. Brown and
CIBC World Markets attended these meetings.

    On January 25, 1999, the corporate development committee of the JDS Board of
Directors consisting of Dr. Abe, Mr. Day, William Sinclair and Robert Enos met
in Toronto to review the status of the merger and to provide direction to JDS
management with respect to the significant remaining issues to be negotiated
with Uniphase. Representatives of CIBC World Markets and JDS' legal advisors
attended this meeting.

    On January 26, 1999, the Uniphase Board of Directors met to discuss the
current status of the proposed Transaction. Copies of the most recent drafts of
the Merger Agreement and other definitive agreements were furnished for review
prior to this meeting. Representatives of BT Alex. Brown also participated in
this meeting.

    On January 27, 1999, the corporate development committee of the JDS Board of
Directors met to again review the status of the negotiations and to discuss
outstanding issues. The corporate development committee also reviewed the latest
draft of the Merger Agreement and the ancillary Transaction documents, copies of
which had been provided for review prior to the meeting. Representatives of CIBC
World Markets and JDS' legal advisors attended this meeting.

    On January 28, 1999, in Tokyo, Japan (January 27, 1999 in Ottawa, Ontario),
the board of directors of Furukawa met to approve the Transaction and the
Furukawa Support Agreement.

                                      S-35

    On January 28, 1999, the Uniphase Board of Directors met to approve the
Transaction. Representatives of BT Alex. Brown attended the meeting and provided
their oral opinion to the Uniphase Board of Directors that the consideration to
be paid by Uniphase to the JDS Shareholders was fair from a financial point of
view to the Uniphase Stockholders as of such date. BT Alex. Brown provided the
written BT Alex. Brown Fairness Opinion to Uniphase later the same day. The
Merger Agreement was presented for consideration at this meeting. The Uniphase
Board of Directors unanimously approved the Transaction and authorized the
execution of the Merger Agreement and the Furukawa Support Agreement.

    On January 28, 1999, the JDS Board of Directors met to approve the
Transaction. Representatives of CIBC World Markets attended the meeting and
provided their oral opinion to the JDS Board of Directors that the Transaction
was fair from a financial point of view to the JDS Shareholders. CIBC World
Markets provided the written CIBC World Markets Fairness Opinion to JDS later
the same day. The Merger Agreement was presented for consideration at this
meeting. The JDS Board of Directors unanimously approved the Transaction and
authorized its officers to execute the Merger Agreement. Immediately following
such meeting, the Merger Agreement and the Furukawa Support Agreement were
executed.

    The terms of the Transaction were publicly announced in a joint press
release issued following the close of trading on January 28, 1999.

    Following the execution and delivery of the Merger Agreement on January 28,
1999, senior officers and advisors of JDS, Uniphase and Furukawa began
considering an alternative structure for the Transaction. As a result of these
considerations, JDS, Uniphase and Exchangeco amended and restated the Merger
Agreement as of April 29, 1999, and JDS, Uniphase, Exchangeco and Furukawa
amended and restated the Furukawa Support Agreement as of the same date.

REASONS FOR THE TRANSACTION

    Uniphase and JDS believe that the Transaction presents an opportunity to
combine complementary products and technologies and to achieve a broad based
leadership position in the rapidly growing market for components and modules for
the fiberoptic telecommunications networking marketplace. JDS and Uniphase
believe that, due to a number of market factors that affect their businesses and
the businesses of their common customer base, the Transaction is appropriate at
this time and in the best interests of both companies and their shareholders,
both now and over the long term.

    The current demand for increased capacity in fiberoptic telecommunications
networks, which is largely the result of increased levels of information
transfer and Internet usage, has caused the complexity and performance
requirements of newly deployed fiberoptic networks to substantially increase and
the product life cycles for these network systems to decrease. OEM system
suppliers are under pressure from their customers to provide higher capacity and
more complex systems in shorter time periods. These same pressures apply at all
levels of their system products, including the component and module levels.
These increasing performance requirements and associated development costs are
making it more difficult for a number of these OEM suppliers to compete
effectively through vertical integration involving production by them of their
own components and modules. The growing complexity of these network systems also
results in a substantial increase in the number of components that the OEM
supplier must utilize to achieve desired system level performance. In lieu of
seeking a different vendor for each of these components, OEM system suppliers
are seeking fewer vendors for a greater variety of components. These OEM
customers also seek more integrated module solutions, which combine a number of
components as a single functional unit within the network architecture. In
addition, a single vendor of multiple components or modules has the ability to
design these products to interact more effectively and to optimize performance
between them when installed in a single network system. Given these factors, JDS
and Uniphase believe there is an increasing trend by their customers to reduce
the level of their vertical integration at the component and module level and to
focus on the overall system design and architecture of their products which has
historically been the primary means by which those OEM system suppliers have
differentiated themselves from their competitors.

                                      S-36

    In this market environment, JDS and Uniphase believe that JDS Uniphase will
be better positioned than the separate companies to meet the evolving needs of
their combined customer base. The following factors are the primary reasons for
this belief:

    - COMBINATION OF LEADING "ACTIVE" AND "PASSIVE" PRODUCTS AND TECHNOLOGIES.
     Uniphase and JDS believe that JDS is an industry leader in the merchant
    optical "passive" market and that Uniphase is a leader in the merchant
    optoelectronic "active" components market. "Active" devices incorporate both
    optical and electronic technology and perform different functions in these
    fiberoptic networks than "passive" devices, which operate only in the
    optical domain of the network. By combining their products and technologies,
    JDS and Uniphase intend that the combined company will continue these
    leadership roles and leverage existing core competencies in each market
    segment to improve product performance in the other segment. Although there
    can be no assurance, Uniphase and JDS also believe that the combination of
    their technologies, financial resources and manufacturing capabilities will
    provide their OEM suppliers with a higher willingness to rely on a third
    party supplier for these critical parts in their fiberoptic network systems.

    - BROADER PRODUCT OFFERING ENABLING "ONE STOP SHOPPING".
     JDS Uniphase will be able to offer each principal type of "active" and
    "passive" component required today by OEM system providers. By combining
    their product lines, JDS and Uniphase will offer their customers the
    opportunity to rely on fewer vendors for their component and module needs.

    - ABILITY TO PROVIDE MODULES.
     JDS Uniphase will be better able to produce certain modules consisting of
    both "passive" and "active" devices. This will enable the combined company
    to optimize the performance of such modules through complementary design of
    the active and passive components.

    - FASTER TIME TO MARKET.
     Although there can be no assurance, Uniphase and JDS believe that the
    breadth of technologies and product lines of JDS Uniphase will enable them
    to respond more quickly to their customers' specifications and to reduce
    product design times.

    - REDUCED COST.
     Through broader based research and development and manufacturing
    activities, it is anticipated that JDS Uniphase will be more cost
    competitive, particularly with the vertically integrated component
    activities of its OEM customers. These anticipated lower costs will assist
    in effectively expanding optical solutions into the shorter distance metro
    and local access networking markets and to position the combined company for
    these potentially large markets as they develop.

    Uniphase and JDS have devoted substantial time and resources to reviewing
the advisability and expected benefits of a merger. In addition to the market
factors described above, Uniphase and JDS believe that they have similar
employee cultures and complementary skills among management and that the two
companies and their operations can be effectively integrated.

    Based on the foregoing, both Uniphase and JDS believe that the proposed
combination of their businesses will be in the best interests of both companies
and fair to their respective shareholders. See "Risk Factors".

RECOMMENDATION OF THE UNIPHASE BOARD OF DIRECTORS

    THE UNIPHASE BOARD OF DIRECTORS BELIEVES THAT THE TRANSACTION IS FAIR TO
UNIPHASE STOCKHOLDERS AND IN THE BEST INTERESTS OF UNIPHASE AND THE UNIPHASE
STOCKHOLDERS. ACCORDINGLY, THE UNIPHASE BOARD OF DIRECTORS HAS UNANIMOUSLY
APPROVED THE TRANSACTION AND RECOMMENDS THAT UNIPHASE STOCKHOLDERS VOTE FOR
APPROVAL OF THE UNIPHASE TRANSACTION PROPOSAL.

    Each of the directors of Uniphase has advised Uniphase that he or she will
vote the Uniphase Common Shares held by him or her in favour of the Uniphase
Transaction Proposal and the Uniphase Additional Proposals.

                                      S-37

    In making its recommendation, the Uniphase Board of Directors considered a
number of factors, including:

    (i) the BT Alex. Brown Fairness Opinion to the effect that, as of the date
        of such opinion, the consideration to be paid by Uniphase to JDS
        Shareholders was fair, from a financial point of view, to Uniphase
        Stockholders;

    (ii) the trading prices of the Uniphase Common Shares and the JDS Common
         Shares prior to January 28, 1999;

   (iii) the opportunity afforded by the Transaction for Uniphase to combine its
         operations with those of JDS (see "The Transaction -- Reasons for the
         Transaction"); and

    (iv) the terms and conditions of the Merger Agreement generally, including
         the circumstances in which the Break Fee is payable by and to Uniphase,
         and the fact that the terms of the Merger Agreement and the Furukawa
         Support Agreement do not prevent a third party from making a competing
         offer or proposing a competing transaction. See "The Merger Agreement".

    In considering the Transaction, the Uniphase Board of Directors recognized
that there were certain risks associated with the Transaction, including the
risk that the potential benefits set forth above may not be realized or that
there may be higher than anticipated costs associated with realizing such
benefits and the facts as set forth in this Supplement under the heading "Risk
Factors".

    In view of the variety of factors considered in connection with its
evaluation of the Transaction, the Uniphase Board of Directors did not consider
it practicable to and did not quantify or otherwise assign relative weights to
the specific factors considered in reaching its determination.

OPINION OF UNIPHASE'S FINANCIAL ADVISOR

    BT Alex. Brown has acted as financial advisor to Uniphase in connection with
the Transaction. At the meeting of the Uniphase Board of Directors on January
28, 1999, BT Alex. Brown rendered its oral opinion, subsequently confirmed in
writing, that as of such date, based upon and subject to the assumptions made,
matters considered and limitations set forth in the BT Alex. Brown Fairness
Opinion and summarized below, the consideration to be paid by Uniphase to JDS
Shareholders was fair, from a financial point of view, to the Uniphase
Stockholders. The BT Alex. Brown Fairness Opinion does not constitute an opinion
as to the value of the Uniphase Common Shares or the Exchangeable Shares or the
prices at any time at which the Uniphase Common Shares or the Exchangeable
Shares will trade. No restrictions or limitations were imposed by the Uniphase
Board of Directors upon BT Alex. Brown with respect to the investigations made
or the procedures followed by BT Alex. Brown in rendering its opinion. BT Alex.
Brown was not requested by the Uniphase Board of Directors to make, and did not
make, any recommendation as to the form or amount of consideration to be paid by
Uniphase pursuant to the Merger Agreement, which issues were resolved in arm's
length negotiations between Uniphase and JDS.

    THE FULL TEXT OF THE BT ALEX. BROWN FAIRNESS OPINION, WHICH SETS FORTH,
AMONG OTHER THINGS, ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED
AND LIMITATIONS ON THE REVIEW UNDERTAKEN BY BT ALEX. BROWN IN CONNECTION WITH
THE BT ALEX. BROWN FAIRNESS OPINION, IS ATTACHED AS APPENDIX H TO THIS
SUPPLEMENT. UNIPHASE STOCKHOLDERS ARE URGED TO READ THE BT ALEX. BROWN FAIRNESS
OPINION CAREFULLY AND IN ITS ENTIRETY. THE BT ALEX. BROWN FAIRNESS OPINION WAS
PREPARED SOLELY FOR THE BENEFIT AND USE OF THE UNIPHASE BOARD OF DIRECTORS IN
ITS CONSIDERATION OF THE TRANSACTION, AND ADDRESSES ONLY THE FAIRNESS OF THE
CONSIDERATION TO BE PAID BY UNIPHASE TO JDS SHAREHOLDERS, FROM A FINANCIAL POINT
OF VIEW, TO THE UNIPHASE STOCKHOLDERS AS OF JANUARY 28, 1999, AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY UNIPHASE STOCKHOLDER AS TO HOW SUCH
STOCKHOLDER SHOULD VOTE AT THE UNIPHASE MEETING. THE BT ALEX. BROWN FAIRNESS
OPINION DOES NOT ADDRESS THE RELATIVE MERITS OF THE TRANSACTION AND ANY OTHER
TRANSACTIONS OR BUSINESS STRATEGIES DISCUSSED BY THE UNIPHASE BOARD OF DIRECTORS
AS ALTERNATIVES TO THE TRANSACTION, OR THE UNDERLYING BUSINESS DECISION TO
PROCEED WITH THE TRANSACTION. THE SUMMARY OF THE BT ALEX. BROWN FAIRNESS OPINION
SET FORTH IN THIS SUPPLEMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
FULL TEXT OF THE BT ALEX. BROWN FAIRNESS OPINION. BT ALEX. BROWN HAS PROVIDED
ITS WRITTEN CONSENT TO THE INCLUSION OF THE BT ALEX. BROWN FAIRNESS OPINION AS
AN APPENDIX TO THIS SUPPLEMENT.

    In connection with BT Alex. Brown's role as financial advisor to Uniphase,
and in arriving at its opinion, BT Alex. Brown reviewed certain publicly
available financial and other information concerning JDS and

                                      S-38

Uniphase and certain internal analyses and other information furnished to BT
Alex. Brown by Uniphase and JDS. BT Alex. Brown has also held discussions with
members of the senior management of JDS and Uniphase regarding the respective
businesses and prospects of JDS and Uniphase and the prospects of a combined
company. In addition, BT Alex. Brown (i) compared certain financial information
for JDS and Uniphase with similar information for companies whose securities are
publicly traded, (ii) reviewed the financial terms of certain recent business
combinations which it deemed to be comparable, (iii) reviewed a draft of the
Merger Agreement and certain related documents, (iv) performed an analysis of
the relative contributions of Uniphase and JDS based on certain pro forma
combined financial information of Uniphase and JDS following consummation of the
Transaction, (v) reviewed the premiums paid in certain recent business
combinations which it deemed to be comparable, and (vi) performed such other
studies and analyses and considered such other factors as it deemed appropriate.

    In preparing the BT Alex. Brown Fairness Opinion, BT Alex. Brown did not
assume responsibility for the verification of, and did not independently verify,
any information, whether publicly available or furnished to it, concerning
Uniphase or JDS, including, without limitation, any financial information,
forecasts or projections considered in connection with the rendering of the BT
Alex. Brown Fairness Opinion. Accordingly, in the preparation of the BT Alex.
Brown Fairness Opinion, BT Alex. Brown assumed the accuracy and completeness of
such information, and that such information was a fair presentation of the
underlying facts and circumstances. BT Alex. Brown received estimates (the
"Estimates") of the projected financial performance of Uniphase and JDS that
were prepared by the management of Uniphase. The Estimates were based in part
upon discussions with the management of JDS and in part upon projections of the
financial performance of Uniphase and JDS made by investment community research
analysts that the management of Uniphase confirmed were generally consistent
with management's expectations. With respect to the information provided to it
regarding the prospects of Uniphase and JDS, and of JDS Uniphase, BT Alex. Brown
assumed that such information reflects the best currently available judgments
and estimates of the management of Uniphase and JDS as to the likely future
financial performance of Uniphase and JDS, and of JDS Uniphase. In addition, BT
Alex. Brown neither conducted, nor was BT Alex. Brown provided with, an
independent evaluation or appraisal of the assets of Uniphase or JDS. The BT
Alex. Brown Fairness Opinion was necessarily based upon economic, market and
other conditions as they existed and could be evaluated as of, and the
information made available to BT Alex. Brown as of, the date of such opinion.
Although subsequent developments may affect the BT Alex. Brown Fairness Opinion,
BT Alex. Brown assumes no obligation to update, revise or reaffirm such opinion.

    For purposes of rendering its opinion, BT Alex. Brown has assumed that, in
all respects material to its analysis, the representations and warranties of
Uniphase and JDS contained in the Merger Agreement are true and correct, that
Uniphase and JDS will each perform all of the covenants and agreements to be
performed by it under the Merger Agreement and all conditions to the obligations
of each of Uniphase and JDS to consummate the Transaction will be satisfied
without any waiver of any material terms or conditions by any party thereto. BT
Alex. Brown has also assumed that the Transaction will be consummated in a
manner that complies in all respects with the applicable provisions of the
Securities Act, the Exchange Act, and all applicable United States federal and
state statutes, rules and regulations and Canadian federal, provincial or
territorial statutes, rules or regulations. BT Alex. Brown has further assumed
that all material governmental, regulatory or other approvals and consents
required in connection with the consummation of the transactions contemplated by
the Merger Agreement will be obtained and that, in connection with obtaining any
necessary governmental, regulatory or other approvals and consents, or any
amendments, modifications or waivers to any agreements, instruments or orders to
which either Uniphase or JDS is a party or subject or by which it is bound, no
limitations, restrictions or conditions will be imposed or amendments,
modifications or waivers made that would have a material adverse effect on
Uniphase or JDS or materially reduce the contemplated benefits of the
Transaction to Uniphase.

    The BT Alex. Brown Fairness Opinion has been provided for the use of the
Uniphase Board of Directors and should not be construed as a recommendation to
any holder of Uniphase Common Shares as to how such stockholder should vote at
the Uniphase Meeting. The BT Alex. Brown Fairness Opinion states that it may not
be used by any person other than the Uniphase Board of Directors without the
prior written consent of BT Alex. Brown. Pursuant to the letter agreement dated
November 10, 1998 between Uniphase and BT Alex. Brown, BT Alex. Brown has
expressly disclaimed any liability by reason of the use of the BT Alex. Brown
Fairness Opinion by any person other than the Uniphase Board of Directors.
Whether or not the BT Alex. Brown

                                      S-39

Fairness Opinion could be relied upon by Uniphase Stockholders to support a
claim against BT Alex. Brown is an issue that, if asserted, would be resolved by
a court of competent jurisdiction. The resolution of such issue would have no
effect on the rights and responsibilities of the Uniphase Board of Directors
under applicable United States law. The availability of a defence would have no
effect on the rights or responsibilities of the Uniphase Board of Directors or
BT Alex. Brown under applicable United States federal securities laws.

    Set forth below is a brief summary of certain financial analyses performed
by BT Alex. Brown in connection with its opinion.

    HISTORICAL FINANCIAL POSITION AND STOCK PRICE PERFORMANCE.  In rendering its
opinion, BT Alex. Brown reviewed and analyzed the historical and current
financial condition of each of Uniphase and JDS, which included (i) an
assessment of the recent financial statements of each of Uniphase and JDS and
(ii) an analysis of the revenue, growth and operating performance trends of each
of Uniphase and JDS. In addition, BT Alex. Brown reviewed and analyzed the daily
closing per share market prices and trading volume for each of the Uniphase
Common Shares and the JDS Common Shares from January 27, 1998 to January 27,
1999.

    ANALYSIS OF SELECTED PUBLICLY TRADED COMPANIES.  BT Alex. Brown compared
certain financial information and commonly used valuation measurements for JDS
to corresponding information and measurements for a group of seven publicly
traded high growth communications companies, consisting of C-Cor Electronics,
Inc., E-TEK Dynamics, Inc., Harmonic Lightwaves, Inc., Ortel Corporation, SDL,
Inc., Uniphase and JDS (collectively, the "Selected Companies"). Such financial
information and valuation measurements included, among other things:

    (i) common equity market valuation;

    (ii) operating performance;

   (iii) ratios of common equity market value as adjusted for debt and cash
         ("Enterprise Value"), and with respect to JDS, the enterprise value
         implied by the Exchange Ratio, based upon the closing stock price of
         the Uniphase Common Shares on January 27, 1999 (the "Implied Enterprise
         Value") to revenues, earnings before interest and taxes ("EBIT") and
         earnings before interest, taxes, depreciation and amortization
         ("EBITDA"); and

    (iv) ratios of common equity market prices per share ("Equity Value") to
         earnings per share ("EPS").

    To calculate the trading multiples for the Selected Companies and JDS, BT
Alex. Brown used publicly available information concerning historical and
projected financial performance for the Selected Companies and, for JDS, the
Estimates. BT Alex. Brown calculated the following trading multiples for JDS and
the Selected Companies:



                                                                                 JDS         SELECTED COMPANIES' RANGE
                                                                              ---------  ---------------------------------
                                                                                   
Multiple of Implied Enterprise Value to 12-Month Revenue(1).................    15.0x            1.2x-17.5x (mean =  8.6x)
Multiple of Implied Enterprise Value to 1998 Revenue(2).....................    15.0x            1.2x-16.1x (mean =  8.1x)
Multiple of Implied Enterprise Value to 1999 Revenue(2).....................    9.0x             1.0x-11.9x (mean =  5.4x)
Multiple of Implied Enterprise Value to 12-Month EBIT(1)....................    48.6x           15.3x-94.2x (mean = 57.6x)
Multiple of Implied Enterprise Value to 1998 EBIT(2)........................    48.6x           16.4x-64.3x (mean = 46.8x)
Multiple of Implied Enterprise Value to 1999 EBIT(2)........................    30.9x            8.2x-57.0x (mean = 30.7x)
Multiple of Implied Enterprise Value to 12-Month EBITDA(1)..................    44.0x            9.8x-72.2x (mean = 41.8x)
Multiple of Implied Enterprise Value to 1998 EBITDA(2)......................    43.9x           10.3x-51.4x (mean = 35.8x)
Multiple of Implied Enterprise Value to 1999 EBITDA(2)......................    27.7x            4.9x-37.5x (mean = 22.4x)
Multiple of Implied Enterprise Value to 12-Month Earnings(1)................    73.0x          22.1x-121.0x (mean = 74.4x)
Multiple of Implied Enterprise Value to 1998 Earnings(2)....................    73.0x           25.7x-95.3x (mean = 72.6x)
Multiple of Implied Enterprise Value to 1999 Earnings(2)....................    48.7x           13.7x-79.0x (mean = 45.5x)

                                      S-40

    Based on the foregoing range of multiples, BT Alex. Brown computed a range
of equity value for JDS of U.S.$4.34 per share to U.S.$77.68 per share, as
compared to the equity value implied by the Exchange Ratio of approximately
U.S.$39.22 per share, based on the closing stock price of Uniphase Common Shares
on January 27, 1999.

    None of the Selected Companies (other than JDS) is identical to JDS.
Accordingly, BT Alex. Brown believes an analysis of publicly traded comparable
companies is not simply mathematical. Rather it involves complex considerations
and qualitative judgments, reflected in the BT Alex. Brown Fairness Opinion,
concerning differences in financial and operating characteristics of the
Selected Companies and other factors that could affect the public trading value
of the Selected Companies.

    ANALYSIS OF SELECTED PRECEDENT TRANSACTIONS.  BT Alex. Brown reviewed the
financial terms, to the extent publicly available, of 11 pending or completed
merger and acquisition transactions since May 22, 1996 involving companies in
the communications industry (collectively, the "Selected Transactions"). BT
Alex. Brown calculated various financial multiples and premiums over market
value based on certain publicly available information for each of the Selected
Transactions and compared them to corresponding financial multiples for the
Transaction, based on the Exchange Ratio. The Selected Transactions reviewed, in
reverse chronological order of public announcement, were: Uniphase
Corporation/Broadband Communications Products, Inc. (November 30, 1998), RELTEC
Corporation/Positron Fiber Systems Corporation (August 11, 1998), Cabletron
Systems, Inc./NetVantage, Inc. (June 22, 1998), World Access, Inc./Telco
Systems, Inc. (June 4, 1998), Alcatel Alsthom SA/DSC Communications Corp. (June
4, 1998), Lucent Technologies/Yurie Systems (April 27, 1998), Uniphase
Corporation/Phillips Optoelectronics, B.V. (April 21, 1998), Tellabs,
Inc./Coherent Communications Systems Corp. (February 16, 1998), Converse
Technology, Inc./Boston Technology, Inc. (August 21, 1997), SystemSoft
Corp./Radish Communications Systems, Inc. (December 12, 1996) and Cabletron
Systems, Inc./ Network Express, Inc. (May 22, 1996). BT Alex. Brown calculated
the following JDS and Selected Company purchase multiples:



                                                                                 JDS         SELECTED COMPANIES' RANGE
                                                                              ---------  ---------------------------------
                                                                                   
Multiple of Adjusted Purchase Price(1) to 12-Month Revenue(2)...............    15.0x            1.6x-16.1x (mean =  7.1x)
Multiple of Adjusted Purchase Price to 12-Month EBIT(2).....................    48.6x           25.1x-84.7x (mean = 52.1x)
Multiple of Purchase Price to Net Income(2).................................    73.0x          30.9x-141.5x (mean = 67.7x)


- - - - - - - - - - ---------------

(1) "Adjusted Purchase Price" means the equity purchase price, as adjusted for
    debt and cash.

(2) Calculated on a trailing 12-month basis.

    Based on the foregoing ranges of multiples, BT Alex. Brown computed a range
of implied equity values per share, as adjusted for debt and cash of U.S.$5.21
to U.S.$75.98, as compared to the equity value implied by the Exchange Ratio of
approximately U.S.$39.22 per share, based on the closing stock price of Uniphase
Common Shares on January 27, 1999. All multiples for the Selected Transactions
were based on public information without taking into account differing market
and other conditions during the thirty month period during which the Selected
Transactions occurred.

    Because the reasons for, and circumstances surrounding, each of the Selected
Transactions were diverse, and due to the inherent differences between the
operations and financial conditions of JDS and the companies involved in the
Selected Transactions, BT Alex. Brown believes that a comparable transaction
analysis is not simply mathematical. Rather, it involves complex considerations
and qualitative judgments, reflected in the BT Alex. Brown Fairness Opinion,
concerning differences between the characteristics of these transactions and the
Transaction that could affect the value of the subject companies and their
business and that of JDS.

    PRO FORMA CONTRIBUTION ANALYSIS.  BT Alex. Brown analyzed the relative
contribution of Uniphase and JDS, as compared to the JDS Shareholders' relative
ownership of approximately 50.0% of the outstanding equity capital of the
combined company, to the pro forma income statement of the combined company,
based on the Estimates. This analysis showed that on a pro forma combined basis
(excluding (i) the effect of any synergies that may be realized as a result of
the Transaction, and (ii) non-recurring expenses relating to the Transaction),
that Uniphase and JDS would account for approximately 48.5% and 51.5%,
respectively, of the combined company's pro forma calendar year 1998 net income,
and approximately 50.0% each of the combined company's

                                      S-41

pro forma calendar year 1999 net income. BT Alex. Brown also analyzed the
relative contributions of Uniphase and JDS, as compared to the JDS Shareholders'
relative ownership of approximately 49.5% of the outstanding equity value, as
adjusted for debt and cash ("Adjusted Market Value") of the combined company.
This analysis showed that on a pro forma basis (excluding (i) the effect of any
synergies that may be realized as a result of the Transaction, and (ii)
non-recurring expenses relating to the Transaction), Uniphase and JDS would
account for the following approximate percentages of the combined company's
financial results:



                                                                                                      UNIPHASE      JDS
                                                                                                      ---------  ---------
                                                                                                           
Percentage of combined company's pro forma 1998 Revenue(1)..........................................    51.9%      48.1%
Percentage of combined company's pro forma 1998 Gross Profit(1).....................................    51.2%      48.8%
Percentage of combined company's pro forma 1998 Operating Income(1).................................    48.3%      51.7%
Percentage of combined company's pro forma 1999 Revenue(1)..........................................    52.5%      47.5%
Percentage of combined company's pro forma 1999 Gross Profit(1).....................................    52.3%      47.7%
Percentage of combined company's pro forma 1999 Operating Income(1).................................    48.7%      51.3%

(1) Calculated on a calendar year basis.

    PRO FORMA TRANSACTION ANALYSIS.  BT Alex. Brown analyzed certain pro forma
effects resulting from the Transaction, including, among other things, the
impact of the Transaction on the projected EPS of Uniphase for calendar year
1999, based on the Estimates. BT Alex. Brown noted that, before taking into
account any non-recurring costs and any charges for goodwill attributable to the
Transaction, the Transaction would be approximately 1.7% accretive to the
combined company's pro forma estimated EPS for calendar year 1999. After taking
into account estimated goodwill attributable to the Transaction, the Transaction
would be approximately 366.5% dilutive to the combined company's pro forma
estimated EPS for calendar year 1999, assuming no write-off for IPRD and a
five-year amortization period. The actual results achieved by the combined
company may vary from projected results and any such variations may be material.

    PREMIUMS PAID AND TRANSACTION OF EQUALS PREMIUM ANALYSIS.  BT Alex. Brown
also reviewed the premiums received by target shareholders in merger of equals
transactions with equal board representation, where the consideration exceeded
U.S.$500 million, from 1994 through 1998, as compared to the market closing
price thirty days prior to, fifteen days prior to and one day prior to the
announcement of such transactions, based on information provided by Securities
Data Corporation. BT Alex. Brown noted that the premiums over the per share
average market closing prices at such points in time for merger of equals
transactions with equal board representation were 11.3%, 10.4%, and 8.3%,
respectively. BT Alex. Brown noted that the premium to be received by the JDS
Shareholders in the Transaction over the per share market closing prices of JDS
over such time periods was 37.2%, 19.0% and 1.8%, respectively.

    The foregoing summary describes all analyses and factors that BT Alex. Brown
deemed material in preparing the BT Alex. Brown Fairness Opinion, but is not a
comprehensive description of all analyses performed and factors considered by BT
Alex. Brown in connection with preparing the BT Alex. Brown Fairness Opinion.
The preparation of a fairness opinion is a complex process involving the
application of subjective business judgment in determining the most appropriate
and relevant methods of financial analysis and the application of those methods
to the particular circumstances and, therefore, is not readily susceptible to
summary description. BT Alex. Brown believes that its analyses must be
considered as a whole and that considering any portion of such analyses and of
the factors considered without considering all analyses and factors could create
a misleading view of the process underlying the BT Alex. Brown Fairness Opinion.
In arriving at its fairness determination, BT Alex. Brown did not assign
specific weights to any particular analyses.

    In conducting its analyses and arriving at its opinions, BT Alex. Brown
utilized a variety of generally accepted valuation methods. The analyses were
prepared solely for the purpose of enabling BT Alex. Brown to provide its
opinion to the Uniphase Board as to the fairness to the Uniphase Stockholders of
the consideration to be paid to the JDS Shareholders in the Transaction, and do
not purport to be appraisals or to necessarily reflect the prices at which
businesses or securities actually may be sold, which are inherently subject to
uncertainty. In connection with its analyses, BT Alex. Brown made, and was
provided by Uniphase and JDS management with, numerous assumptions with respect
to industry performance, general business and economic conditions and other
matters, many of which are beyond the control of Uniphase or JDS. Analyses based
on

                                      S-42

estimates or forecasts of future results are not necessarily indicative of
actual past or future values or results, which may be significantly more or less
favorable than suggested by such analyses. Because such analyses are inherently
subject to uncertainty, being based upon numerous factors or events beyond the
control of Uniphase, JDS or their respective advisors, none of Uniphase, BT
Alex. Brown or any other person assumes responsibility if future results or
actual values are materially different from these forecasts or assumptions.

    Uniphase selected BT Alex. Brown as financial advisor in connection with the
Transaction based on BT Alex. Brown's qualifications, expertise, reputation and
experience in mergers and acquisitions, and based on BT Alex. Brown's
familiarity with Uniphase and the high-growth communications industry. In
connection with the Transaction, Uniphase retained BT Alex. Brown pursuant to a

RECOMMENDATION OF THE JDS BOARD OF DIRECTORS

    THE JDS BOARD OF DIRECTORS BELIEVES THAT THE ARRANGEMENT IS FAIR TO JDS
SHAREHOLDERS AND IN THE BEST INTERESTS OF JDS. ACCORDINGLY, THE JDS BOARD OF
DIRECTORS HAS UNANIMOUSLY APPROVED THE ARRANGEMENT AND RECOMMENDS THAT JDS
SHAREHOLDERS VOTE FOR APPROVAL OF THE JDS ARRANGEMENT RESOLUTION.

    Each of the directors of JDS has advised JDS that he or she will vote the
JDS Common Shares held by him or her, directly or indirectly, in favour of the
JDS Arrangement Resolution.

    In making its recommendation, the JDS Board of Directors considered a number
of factors, including:

    (i) the Exchange Ratio offered by Uniphase which, based upon the closing
        price as of January 27, 1999 of Uniphase Common Shares and an exchange
        rate of Cdn.$1.5199 for U.S.$1.00, represented an estimated value of
        Cdn.$59.61 per JDS Common Share and a premium of approximately 23.9% to
        the preceding 20 day average trading price on the TSE of the JDS Common
        Shares;

    (ii) the CIBC World Markets Fairness Opinion to the effect that, at the date
         of such opinion, the Transaction was fair from a financial point of
         view to the JDS Shareholders;

   (iii) the fact that Furukawa, a substantial JDS Shareholder, has agreed to
         vote in favour of the Arrangement;

    (iv) the trading prices of the Uniphase Common Shares prior to January 28,
         1999;

    (v) the opportunity afforded by the Arrangement for JDS to combine its
        operations with those of Uniphase (see "The Transaction -- Reasons for
        the Transaction");

    (vi) the structure of the Arrangement which effectively (A) permits JDS
         Shareholders who are Canadian Residents to elect to receive
         Exchangeable Shares without realizing a gain provided the adjusted cost
         base of the JDS Shareholder's JDS Common Shares exceeds the sum of any
         cash received in lieu of fractional Exchangeable Shares and the fair
         market value of the Ancillary Rights and Exchangeable

                                      S-43

         Share Rights received on the exchange and (B) permits JDS Shareholders
         who are Canadian Residents and who elect to receive Exchangeable Shares
         to hold the Exchangeable Shares in their registered pension plans,
         RRSPs, RRIFs and DPSPs, as the Exchangeable Shares will not be foreign
         property under the Canadian Tax Act for trusts governed by any of such
         plans provided the Exchangeable Shares are listed on a prescribed stock
         exchange in Canada (which currently includes the TSE); and

   (vii) the terms and conditions of the Merger Agreement generally, including
         the circumstances in which the Break Fee is payable by and to JDS, and
         the fact that the terms of the Merger Agreement do not prevent a third
         party from making a competing offer or proposing a competing
         transaction. See "The Merger Agreement".

    In considering the Transaction, the JDS Board of Directors recognized that
there were certain risks associated with the Transaction, including the risk
that the potential benefits set forth above may not be realized or that there
may be higher than anticipated costs associated with realizing such benefits and
the factors set forth in this Supplement under "Risk Factors".

    In view of the variety of factors considered in connection with its
evaluation of the Transaction, the JDS Board of Directors did not consider it
practicable to and did not quantify or otherwise assign relative weights to the
specific factors considered in reaching its determination.

OPINION OF JDS' FINANCIAL ADVISOR

    Pursuant to a letter agreement dated November 23, 1998 between JDS and CIBC
World Markets, CIBC World Markets provided a fairness opinion to the JDS Board
of Directors in connection with the Transaction. At the meeting of the JDS Board
of Directors on January 28, 1999, CIBC World Markets rendered its oral opinion,
subsequently confirmed in writing the same day, that as of such date, based upon
and subject to the various considerations set forth in the CIBC World Markets
Fairness Opinion, the Transaction was fair, from a financial point of view, to
the JDS Shareholders. The CIBC World Markets Fairness Opinion does not
constitute an opinion as to the value of the JDS Common Shares or the prices at
any time at which the JDS Common Shares, the Uniphase Common Shares or the
Exchangeable Shares will trade. No restrictions or limitations were imposed by
the JDS Board of Directors upon CIBC World Markets with respect to the
investigations made or the procedures followed by CIBC World Markets in
rendering its opinion. CIBC World Markets was not requested by the JDS Board of
Directors to make any recommendations as to the form or amount of consideration
to be paid pursuant to the Merger Agreement, which issues were resolved in arm's
length negotiations between JDS and Uniphase.

    THE FULL TEXT OF THE CIBC WORLD MARKETS FAIRNESS OPINION, WHICH SETS FORTH,
AMONG OTHER THINGS, ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED
AND LIMITATIONS ON THE SCOPE OF THE REVIEW UNDERTAKEN BY CIBC WORLD MARKETS IN
RENDERING THE CIBC WORLD MARKETS FAIRNESS OPINION, IS ATTACHED AS APPENDIX I TO
THIS SUPPLEMENT. JDS SHAREHOLDERS ARE URGED TO READ THE CIBC WORLD MARKETS
FAIRNESS OPINION CAREFULLY AND IN ITS ENTIRETY. THE CIBC WORLD MARKETS FAIRNESS
OPINION ADDRESSES ONLY THE FAIRNESS OF THE TRANSACTION, FROM A FINANCIAL POINT
OF VIEW, TO THE JDS SHAREHOLDERS AS OF JANUARY 28, 1999, AND DOES NOT CONSTITUTE
A RECOMMENDATION TO ANY JDS SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE
AT THE JDS MEETING. THE SUMMARY OF THE CIBC WORLD MARKETS FAIRNESS OPINION SET
FORTH IN THIS SUPPLEMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL
TEXT OF THE CIBC WORLD MARKETS FAIRNESS OPINION. CIBC WORLD MARKETS HAS PROVIDED
ITS WRITTEN CONSENT TO THE INCLUSION OF THE CIBC WORLD MARKETS FAIRNESS OPINION
IN THIS SUPPLEMENT.

    In preparing its opinion, CIBC World Markets reviewed and relied upon, or
undertook, among other things:

    (i) the Merger Agreement;

    (ii) annual reports of JDS for the fiscal years ended May 31, 1994, 1995,
         1996, 1997 and 1998 and the unaudited interim financial statements for
         the six months ended November 30, 1998;

   (iii) annual reports of Uniphase for the fiscal years ended June 30, 1994,
         1995, 1996, 1997 and 1998 and the unaudited interim financial
         statements for the three months ended September 30, 1998;

    (iv) the Annual Information Form of JDS for the year ended May 31, 1998;

    (v) the JDS Management Proxy Circular dated September 3, 1998;

                                      S-44

    (vi) the Annual Report on Form 10-K of Uniphase for the fiscal year ended
         June 30, 1998 and the Quarterly Report on Form 10-Q for the quarter
         ended September 30, 1998;

   (vii) the Proxy Statement for the annual meeting of stockholders of Uniphase
         dated November 10, 1998;

  (viii) discussions with members of the management of each of JDS and Uniphase
         concerning their respective current and future business operations,
         financial condition and operating results and prospects;

    (ix) Uniphase's 1998 and 1999 year-to-date financial results vs. budget;

    (x) Uniphase's 1998 operating plan;

    (xi) conversations with other professional advisors assisting JDS during its
         due diligence process and related due diligence reports;

   (xii) other publicly available information regarding JDS' and Uniphase's
         operations, including industry and analysts' research reports;

  (xiii) certain financial and stock market data of JDS, Uniphase and other
         companies in the fiberoptics industry;

   (xiv) certain recent public and non-public transactions in the fiberoptics
         industry;

   (xv) a certificate dated the date of the CIBC World Markets Fairness Opinion
        from the President and Chief Executive Officer of JDS as to the accuracy
        and completeness of the information provided to CIBC World Markets in
        connection with JDS; and

   (xvi) such other information, financial studies, analyses and investigations
         and financial, economic and market criteria that CIBC World Markets
         deemed relevant.

    In delivering its opinion, CIBC World Markets relied upon and assumed
without independent verification the completeness, accuracy and fair
presentation of all the financial and other information, data, advice, opinions
and representations obtained by it from public sources, JDS, senior management
of JDS and Uniphase and agents for and advisors to JDS and Uniphase.

    In preparing its opinion, CIBC World Markets made several assumptions,
including the assumption that all of the conditions required to complete the
Transaction will be met and that the representations and warranties in the
Merger Agreement with respect to JDS, Uniphase, their respective subsidiaries
and the Transaction are accurate in all material respects.

    The CIBC World Markets Fairness Opinion was rendered on the basis of
securities markets and economic, financial and general business conditions
prevailing as at the date thereof. In its analyses and in preparing the opinion,
CIBC World Markets made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond the control of CIBC World Markets or any party involved in the
Transaction.

    The CIBC World Markets Fairness Opinion has been provided for the use of the
JDS Board of Directors and should not be construed as a recommendation to any
holder of JDS Common Shares as to whether to vote in favour of the Transaction.
The CIBC World Markets Fairness Opinion states that it may not be used by any
person or relied upon by any person other than the JDS Board of Directors
without the express prior written consent of CIBC World Markets. Pursuant to the
letter agreement dated November 23, 1998 between JDS and CIBC World Markets,
CIBC World Markets has expressly disclaimed any liability by reason of the use
of the CIBC World Markets Fairness Opinion by any person other than the JDS
Board of Directors. Whether or not the CIBC World Markets Fairness Opinion could
be relied upon by JDS Shareholders to support a claim against CIBC World Markets
is an issue that, if asserted, would be resolved by a court of competent
jurisdiction. The resolution of such issue would have no effect on the rights
and responsibilities of the JDS Board of Directors under applicable Canadian or
United States law. The availability of a defence would have no effect on the
rights or responsibilities of the JDS Board of Directors or CIBC World Markets
under applicable United States federal securities laws.

                                      S-45

    Based on the foregoing information, CIBC World Markets performed a variety
of financial analyses of the Transaction. The following paragraphs summarize the
material financial analyses performed by CIBC World Markets in arriving at its
opinion, which analyses were presented to the JDS Board of Directors.

    ANALYSIS OF COMPARABLE COMPANIES.  Using publicly available information,
CIBC World Markets compared selected historical and projected financial and
market data ratios for JDS and Uniphase to the corresponding data and ratios of
certain other publicly traded optical networking and related comparable
companies. CIBC World Markets determined certain other public companies to be
generally comparable to JDS and Uniphase based on their lines of business and
relative size (collectively, the "Selected Companies"). These companies
consisted of E-TEK Dynamics Inc., SDL Inc., MRV Communications Inc., Vitesse
Semiconductor Corporation and Broadcom Corporation. All historically based
ratios were computed from public information disclosed in the Selected
Companies' year-end and quarterly reports. Ratios of total market capitalization
to projected earnings were based on mean per-share earnings estimates of
Institutional Brokers Estimate Services for JDS, Uniphase and the Selected
Companies.

    CIBC World Markets calculated multiples for JDS and Uniphase based on the
closing prices of JDS Common Shares and Uniphase Common Shares on January 27,
1999 of Cdn.$58.50 and U.S.$77.13 per share, respectively. As well, CIBC World
Markets derived the implied transaction multiples for January 27, 1999,
calculated using the closing prices, a Cdn.$/U.S.$ exchange rate of 1.519 and
the Exchange Ratio. Mean multiples for the Selected Companies were adjusted to
exclude those values lying more than one standard deviation from the mean, a
statistical method of excluding extreme values that could skew the mean of the
total data sample. For the Selected Companies, the calculated multiples are
provided in the table below.



                                                                                     PRICE/1-YEAR         PRICE/2-YEAR

    ANALYSIS OF SELECTED PRECEDENT TRANSACTIONS.  CIBC World Markets analyzed
publicly available information for 13 selected mergers and acquisitions since
April 22, 1996 involving companies in the technology and telecommunications
sectors (collectively, the "Selected Transactions"). In examining these
transactions, CIBC World Markets analyzed certain parameters of the acquired
companies' common stock relative to the corresponding parameters based on the
Exchange Ratio. Such parameters included various financial multiples and
premiums over market value based on certain publicly available information for
each of the Selected Transactions. The Selected Transactions were: Cisco Systems
Inc./StrataCom Inc. (April 22, 1996), 3Com Corporation/US Robotics Corp.
(February 26, 1997), Ascend Communications Inc./Cascade Communications
Corporation (March 31, 1997), Lucent Technologies, Inc./Octel Communications
Corp. (July 17, 1997), Comverse Technology Inc./Boston Technology Inc. (August
21, 1997), Tellabs Inc./Coherent Communications Systems Corp. (February 16,
1998), Uniphase Corporation/Philips Optoelectronics BV (April 21, 1998), Lucent
Technologies, Inc./Yurie Systems Inc. (April 27, 1998), Alcatel Alsthom CGE/DSC
Communications Corporation (June 4, 1998), World Access Inc./Telco Systems Inc.
(June 4, 1998), Northern Telecom Limited/Bay Networks Inc. (June 15, 1998),
Cabletron Systems Inc./NetVantage Inc. (June 22, 1998) and Reltec Corporation/
Positron Fiber Systems Corporation (August 11, 1998).

    For each of the Selected Transactions, CIBC World Markets calculated the
multiple of the enterprise value of the acquired entity (equity purchase price
plus debt less cash) to both revenue and earnings before interest and taxes
("EBIT") of the acquired entity, and also calculated the multiple of the equity
purchase price to

                                      S-46

earnings of the acquired entity. The following table sets forth the high, low
and adjusted mean of these multiples and the implied transaction multiples.



                                                                         ENTERPRISE VALUE/  ENTERPRISE VALUE/    PRICE/

    No company, transaction or business used as a comparison in this "Analysis
of Selected Precedent Transactions" or in the "Analysis of Comparable Companies"
is identical to JDS, Uniphase or the Transaction. Accordingly, these analyses
are not simply mathematical; rather, they involve complex considerations and
judgments concerning differences in the financial and operating characteristics
and other factors that could affect the acquisition, public trading or other
values of the selected transactions, or the business segment, company or
transaction to which they are being compared.

    MARKET CAPITALIZATION ANALYSIS.  CIBC World Markets reviewed the stock
market price performance of JDS Common Shares and Uniphase Common Shares in
relation to each other over the 1, 10, 30, 60, 90, 180 and 360 days ending
January 27, 1999. According to this analysis, the implied ownership by JDS
Shareholders of the combined company would equal between 34.1% and 49.0%.

    CONTRIBUTION ANALYSIS.  CIBC World Markets reviewed and analyzed pro forma
revenue, gross profit, operating income, pre-tax profit and net income
contribution of both JDS and Uniphase in JDS Uniphase on a historical and
projected basis. Forecast results were based on actual historical results, a
review of industry and company research, and discussions with JDS and Uniphase
management. CIBC World Markets calculated JDS' share of combined pre-tax profit
and net income based on pro forma fiscal 1998, pro forma latest-twelve-months,
and pro forma fiscal 1999 figures as provided in the table below. As well, CIBC
World Markets calculated JDS' share of combined revenue, gross profit, earnings
before interest, taxes, depreciation and amortization ("EBITDA") in the combined
company, which was analyzed relative to the equity value of the combined company
as adjusted for net debt.



                                                                                        GROSS                  PRE-TAX      NET

                                                                         -----------  ---------  -----------  ---------  ---------
                                                                                                          
Pro Forma 1998.........................................................       47.7%       48.6%       48.3%       51.4%      51.4%
Pro Forma Last Twelve Months...........................................       48.6%       50.3%       49.0%       52.8%      52.0%
Pro Forma 1999 Estimate................................................       49.6%       50.3%       52.7%       53.8%      52.3%


    DISCOUNTED CASH FLOW ANALYSIS.  CIBC World Markets performed a discounted
cash flow ("DCF") analysis for both JDS and Uniphase on a stand-alone basis
using underlying operating projections based on actual historical results, a
review of industry and company research, and discussions with JDS and Uniphase
management. Using a range of discount rates, CIBC World Markets calculated
estimates of net present value of free unlevered cash flows for the years 1999
through 2003 and of the forecast free cash flow as at the end of 2003 assuming a
range of perpetual growth rates. After calculating these present value estimates
of all future unlevered free cash flows, CIBC World Markets added each of JDS'
and Uniphase's cash to and subtracted each company's debt from these estimates
to arrive at present value estimates attributable to the common equity for each
company. Based on this analysis, the implied value of JDS' equity equalled
between 44.3% to 56.7% of the implied value of the combined company's equity.

    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In arriving
at its opinion, CIBC World Markets considered the results of all of its analyses
as a whole and did not attribute any particular weight to any analysis or factor
considered by it. Furthermore, CIBC World Markets believes that selecting any
portion of its analyses, without considering all analyses, would create an
incomplete view of the process underlying its opinion. The analyses which CIBC
World

                                      S-47

Markets performed are not necessarily indicative of actual value or actual
future results, which may be more or less favourable than those suggested by
such analyses.

    CIBC World Markets is an internationally recognized investment banking firm
that provides financial services in connection with a wide range of business
transactions. As part of its business, CIBC World Markets regularly engages in
the valuation of companies and their securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and other
transactions. JDS retained CIBC World Markets based upon CIBC World Markets'
expertise in the valuation of companies, as well as its familiarity with JDS and
other telecommunications companies. The CIBC World Markets Fairness Opinion
represents the opinion of CIBC World Markets and the form and content thereof
have been approved for release by a committee of its directors, each of whom is
experienced in merger, acquisition, divestiture and fairness opinion matters. In
the ordinary course of its business, CIBC World Markets may actively trade the
equity securities of JDS and Uniphase for its own account and for the accounts
of customers and, accordingly, may at any time hold a long or short position in
such securities. In addition, CIBC World Markets has previously rendered
investment banking and financial advisory services to JDS for which it received
customary compensation, including acting as lead manager in the underwriting of
securities of JDS in the past 24 months. Further, CIBC World Markets acted as
underwriter in the sale by Furukawa of 3,130,000 JDS Common Shares on February
16, 1999. See "The Transaction -- Interests of Certain Persons in the
Transaction" and "The Companies after the Transaction -- Principal Holders of
Securities".

    Pursuant to its letter agreement with CIBC World Markets, JDS has agreed to
pay CIBC World Markets fees of Cdn.$5 million for rendering its financial
advisory services. JDS has also agreed to indemnify CIBC World Markets and
certain related persons against certain liabilities in connection with the
engagement of CIBC World Markets, including certain liabilities under Canadian
and U.S. securities laws.

INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION

    In considering the respective recommendations of the Uniphase Board of
Directors and JDS Board of Directors with respect to the Transaction, Uniphase
Stockholders and JDS Shareholders should each be aware that certain members of
the management and board of directors of each of Uniphase and JDS have certain
interests in the Transaction, including those referred to below, that may
present them with actual or potential conflicts of interest in connection with
the Transaction. Each of the Uniphase Board of Directors and the JDS Board of
Directors was aware of these interests and considered them along with the other
matters described in "The Transaction -- Recommendation of the Uniphase Board of
Directors" and "The Transaction -- Recommendation of the JDS Board of
Directors".

    The Board of Directors of JDS Uniphase immediately following the Effective
Time will consist of a number of the current directors of each of Uniphase and
JDS. In addition, pursuant to the Merger Agreement, Uniphase has agreed to offer
to retain certain members of the management of Uniphase and JDS pursuant to
retention agreements which will provide for certain payments to each of those
employees in the event of termination of their employment without cause, or upon
death, disability or resignation of or by the employee in certain instances at
any time within five years of the date of their retention agreement. Such
employees will also be released, in such events, from the vesting and other
conditions placed on their options and other securities on the date of grant or
issuance thereof. Certain of the retention agreements will provide for the grant
of certain rights to the particular employee in the event of a change of control
of JDS Uniphase. Uniphase has also agreed to grant options in respect of an
aggregate of 4,110,260 Uniphase Common Shares effective at the Effective Time to
be allocated to JDS employees designated by the Chief Executive Officer of JDS
with the prior approval of the compensation committee of the JDS Board of
Directors. See "The Transaction -- Arrangements Respecting Options".

    Pursuant to the Furukawa Support Agreement, Uniphase has agreed, for the
benefit of Furukawa, to execute the Furukawa Registration Rights Agreement on or
prior to the Effective Date with respect to the Uniphase Common Shares and
Exchangeable Shares to be held by a subsidiary or subsidiaries of Furukawa. Four
members of the JDS Board of Directors are affiliated with Furukawa; such
directors will not be among the initial directors of JDS Uniphase. See "The
Transaction -- Furukawa Support Agreement" and "The Companies after the
Transaction".

                                      S-48

    The Merger Agreement provides that all rights to indemnification for
officers and directors of JDS or any subsidiary as provided in the JDS Articles,
JDS By-laws, or the articles or bylaws of any subsidiary of JDS, in effect on
January 28, 1999, will survive the Arrangement for a period of not less than six
years from the Effective Time and JDS Uniphase will assume, effective upon
consummation of the Arrangement, all such liability with respect to any matters
arising prior to the Effective Time. The Merger Agreement also provides that,
for not less than six years from the Effective Time, there shall be maintained
in effect coverage equivalent to that in effect under current policies of the
directors' and officers' liability insurance maintained by JDS which is no less
advantageous, and with no gaps or lapses in coverage, with respect to matters
occurring prior to the Effective Time.

    Four officers of Uniphase, Kevin Kalkhoven, Anthony Muller, Dan Pettit,
Senior Vice-President and President, Uniphase Europe, and Michael Phillips are
parties to certain agreements that may cause the vesting of any options to
acquire Uniphase Common Shares they hold to accelerate on completion of the
Transaction. Each of these Uniphase officers has agreed that the vesting of his
options will not be accelerated as a result of the Transaction under such
agreements.

FURUKAWA SUPPORT AGREEMENT

    The Uniphase Parties have entered into the Furukawa Support Agreement with
Furukawa and JDS pursuant to which Furukawa has irrevocably agreed:

    (i) that it will not, directly or indirectly, solicit or initiate (including
        by way of furnishing information or entering into any form of agreement
        or arrangement) any inquiries or proposals regarding any Inconsistent
        Transaction involving JDS, other than as set forth in the Furukawa
        Support Agreement;

    (ii) to vote its JDS Common Shares in favour of the Arrangement or any JDS
         Alternative Transaction;

   (iii) to vote its JDS Common Shares against any Inconsistent Transaction;

    (iv) not to exercise any Dissent Rights; and

    (v) with the exception of certain permitted transfers, not to sell or
        otherwise transfer any of its JDS Common Shares prior to the Effective
        Time without the prior consent of Uniphase. Pursuant to the Furukawa
        Support Agreement, Furukawa is permitted to transfer its JDS Common
        Shares to any of its Affiliates provided such Affiliate agrees to be
        bound by the Furukawa Support Agreement. In addition, Furukawa is
        permitted to sell up to 14% of its JDS Common Shares (approximately 7%
        of the outstanding JDS Common Shares) prior to the Effective Time,
        provided that Furukawa either retains the right to vote or to cause to
        be voted such JDS Common Shares in connection with the Arrangement or
        obtains the written agreement of the transferee to be bound by the
        provisions of the Furukawa Support Agreement regarding (A) the voting of
        such JDS Common Shares in connection with the Arrangement and (B) the
        restrictions regarding transfers of such JDS Common Shares prior to the
        Effective Time. In accordance with this provision, on February 16, 1999,
        Furukawa sold 3,130,000 JDS Common Shares (approximately 4% of the
        outstanding JDS Common Shares). Furukawa has retained the right to vote
        these shares at the JDS Meeting. See "The Companies after the
        Transaction -- Principal Holders of Securities".

    The obligations of Furukawa to support the Arrangement and to perform
certain of its obligations contained in the Furukawa Support Agreement are
subject to certain conditions including: (i) the absence of any order or decree,
or any proceeding which, if successful, would result in an order or ruling, that
would, preclude Furukawa from performing such obligations; (ii) receipt by
Furukawa or its affiliates of an opinion of Osler, Hoskin & Harcourt regarding
certain matters under the Canadian Tax Act; (iii) confirmation from the Japanese
taxation authorities that the conversion of Furukawa's JDS Common Shares into
Class B Non-Voting Preference Shares and the exchange thereof for Exchangeable
Shares and ancillary rights will occur on a tax-free basis under the taxation
laws of Japan; (iv) receipt by JDS of an opinion from an independent valuator as
to the nominal fair market value of the Ancillary Rights, the Call Rights and
certain rights provided to Furukawa pursuant to the Furukawa Support Agreement;
and (v) receipt by Uniphase of an opinion letter from Morrison & Foerster LLP,
upon which Furukawa and its affiliates shall be entitled to rely regarding
certain matters under the Code. In addition, Furukawa has the right to terminate
the Furukawa Support Agreement if the conditions set forth in subparagraphs
(ii), (iii) and (v) above have not been satisfied as of the Effective Date

                                      S-49

or if, on the Effective Date, (x) the Furukawa Registration Rights Agreement has
not been executed by Uniphase and Exchangeco, (y) certain amendments to the
Uniphase Rights Agreement have not been made, or (z) all or a portion of the
professional fees incurred by Furukawa in assessing JDS Alternative Transactions
have not been reimbursed by Uniphase or JDS. See "Uniphase Capital
Stock -- Uniphase Rights Agreement".

    In addition, Furukawa has agreed that neither it nor any of its Affiliates
shall, without the prior written consent of Uniphase, transfer, directly or
indirectly, after the Effective Date, Exchangeable Shares or Uniphase Common
Shares representing 10% or more of the total combined voting power of the then
outstanding Exchangeable Shares and Uniphase Common Shares, taken together, to
any one Person that is (i) a Uniphase competitor as described in Uniphase's most
recent Form 10-K or any subsequent filing made by Uniphase with the SEC; or (ii)
a Person, who directly or indirectly, has either (A) previously sought to
acquire a controlling interest (being 50% of the combined voting power) in a
publicly traded corporation through a hostile tender offer or other structure
not approved by the board of directors of the target corporation, and who
Uniphase reasonably determines, based upon credible external information,
intends to make such a hostile bid to acquire a controlling interest in
Uniphase; or (B) publicly disclosed an intention to acquire, directly or
indirectly, any combination of Uniphase Common Shares and Exchangeable Shares
representing more than 50% of the total combined voting power of Uniphase Common
Shares and Exchangeable Shares then outstanding, taken together.

    In the Furukawa Support Agreement, Uniphase and Exchangeco have agreed that,
notwithstanding the terms and conditions of the Exchangeable Shares and provided
that Furukawa owns at least 992,372 Exchangeable Shares, the Redemption Date
shall not be established by the board of directors of Exchangeco as any date
earlier than March 31, 2014 and Exchangeco will not voluntarily initiate, or
consent to the initiation of, any liquidation, dissolution or winding-up of
Exchangeco or other distribution of its assets among its shareholders for the
purpose of winding-up of its affairs, in each case without the prior written
consent of Furukawa. See "Description of Exchangeable Shares -- Early
Redemption".

    The Furukawa Support Agreement provides that it will be terminated upon the
first to occur of:

    (i) the date of the termination of the Merger Agreement by the Uniphase
        Parties or by JDS, or the date of mutual termination of the Merger
        Agreement by the Uniphase Parties and JDS;

    (ii) the date of notice by Furukawa to the Uniphase Parties that the JDS
         Board of Directors has, in accordance with the Merger Agreement,
         determined that an Acquisition Proposal constitutes a Superior
         Transaction;

   (iii) September 30, 1999, in the event the Effective Date has not occurred on
         or prior to such date, subject to extension by mutual agreement; and

    (iv) the date which is 10 years after the Effective Date, subject to earlier
         termination by Furukawa or Uniphase in the event the members of the
         Furukawa group of companies own, in the aggregate, either more than 50%
         or less than 10% of the total combined voting power of all outstanding
         Uniphase Common Shares.

    The Furukawa Support Agreement provides that the Uniphase Parties and a
wholly-owned subsidiary or subsidiaries of Furukawa will enter into the Furukawa
Registration Rights Agreement on or before the Effective Date. Pursuant to the
Furukawa Registration Rights Agreement, upon request and in specified
circumstances, Uniphase or Exchangeco, as the case may be, will register or
qualify Uniphase Common Shares or Exchangeable Shares held by a subsidiary (or
its permitted transferees) under United States securities laws (with respect to
the Uniphase Common Shares) or Canadian securities laws (with respect to the
Exchangeable Shares) in order to facilitate the sale of such shares.

    The Furukawa Registration Rights Agreement will restrict the number of times
registration or qualification may be requested to once per twelve-month period
and to a total of five times. The Furukawa Registration Rights Agreement will
also provide the subsidiary or subsidiaries of Furukawa with certain rights to
have its or their Uniphase Common Shares or Exchangeable Shares registered or
qualified when JDS Uniphase or Exchangeco, as the case may be, effects a
registration or qualification of its shares. The rights provided in the Furukawa
Registration Rights Agreement expire upon the earlier of 10 years from the date
of the agreement or, with respect to a subsidiary of Furukawa or a particular
transferee, when that shareholder holds less than 1% of the outstanding Uniphase
Common Shares and Exchangeable Shares then outstanding, taken together.

                                      S-50

SHAREHOLDER APPROVAL AND THE SPECIAL MEETINGS

UNIPHASE

    The Uniphase Meeting will be held on June 28, 1999. At the Uniphase Meeting,
the Uniphase Stockholders will be asked to approve the Uniphase Transaction
Proposal and the Uniphase Additional Proposals.

    For the purpose of approving the Uniphase Transaction Proposal, a quorum of
a majority of the Uniphase Common Shares outstanding on the Uniphase Record Date
is required at the Uniphase Meeting. The Uniphase Transaction Proposal must be
approved by the affirmative vote of the holders of a majority of the total votes
cast at the Uniphase Meeting. The required approvals for the Uniphase Additional
Proposals are set out in the Uniphase Proxy Statement. Uniphase Stockholders
should review in its entirety the Uniphase Proxy Statement for further
information regarding the Uniphase Meeting.

JDS

    The JDS Meeting will be held on June 28, 1999. At the JDS Meeting, the JDS
Shareholders will be asked to approve the JDS Arrangement Resolution.

    Pursuant to the Interim Order, the JDS Arrangement Resolution must be
approved by 66 2/3% of the votes cast by holders of JDS Common Shares present or
voting by proxy at the JDS Meeting. As at May 14, 1999, JDS' issued and
outstanding share capital consisted of 78,411,178 JDS Common Shares. Furukawa
owns 37,359,670 JDS Common Shares (approximately 47.6% of the JDS Common Shares)
and has agreed to vote its JDS Common Shares in favour of the Arrangement.
Furukawa also has the right to vote, at the JDS Meeting, the 3,130,000 JDS
Common Shares (approximately 4% of the JDS Common Shares) it recently sold and
has agreed to vote such shares in favour of the Arrangement. See "The
Transaction -- Furukawa Support Agreement". Subject to applicable law, each JDS
Shareholder is entitled to one vote for each JDS Common Share held at the close
of business on May 25, 1999. JDS Shareholders should review in its entirety the
JDS Circular for further information regarding the JDS Meeting.

COURT APPROVAL OF THE ARRANGEMENT AND COMPLETION OF THE TRANSACTION

    An arrangement under the CBCA requires approval by the Court. Prior to the
mailing of the JDS Circular, JDS obtained the Interim Order providing for the
calling and holding of the JDS Meeting and other procedural matters. A copy of
each of the Interim Order and the Notice of Application is attached hereto as
Appendix B.

    Subject to the approval of the JDS Arrangement Resolution by the JDS
Shareholders at the JDS Meeting and the approval of the Uniphase Transaction
Proposal by the Uniphase Stockholders at the Uniphase Meeting, the hearing in
respect of the Final Order is scheduled to take place on or about June 30, 1999
at 10:00 a.m. (Toronto time) in the Court at 393 University Ave., Toronto,
Ontario. Any JDS Shareholder who wishes to appear or be represented and to
present evidence or arguments must serve and file a notice of appearance as set
out in the Notice of Application for the Final Order and satisfy any other
requirements of the Court. The Court will consider, among other things, the
fairness and reasonableness of the Arrangement. The Court may approve the
Arrangement in any manner the Court may direct, subject to compliance with such
terms and conditions, if any, as the Court deems fit.

    Assuming the Final Order is granted and the other conditions to closing
contained in the Merger Agreement are satisfied or waived, it is anticipated
that the following will occur substantially simultaneously: Articles of
Arrangement for JDS will be filed with the Director under the CBCA to give
effect to the Arrangement; the Voting and Exchange Trust Agreement and the
Exchangeable Share Support Agreement will be executed and delivered; and the
various other documents necessary to consummate the transactions contemplated
under the Merger Agreement will be executed and delivered.

    Subject to the foregoing, it is expected that the Effective Time will occur
as soon as practicable after the requisite Uniphase Stockholder and JDS
Shareholder approvals have been obtained.

ANTICIPATED ACCOUNTING TREATMENT

    The Transaction will be accounted for by JDS Uniphase under the purchase
method of accounting. Under purchase accounting, the estimated market value of
Uniphase Common Shares and the Exchangeable Shares issued in the Arrangement,
the fair value of the Replacement Options and the amount of the direct
transaction

                                      S-51

costs will be recorded as the cost of acquiring the business of JDS. That cost
will be allocated to the individual assets acquired and liabilities assumed,
including various identifiable intangible assets such as IPRD, acquired
technology, acquired trademarks and tradenames and acquired workforce, based on
their respective fair values. The excess of the purchase cost over the fair
value of the net assets is allocated to goodwill. IPRD, which is currently
estimated at U.S.$177 million, will be expensed immediately. Intangible assets
including goodwill will be amortized over a five year period. As described in
the JDS Uniphase Unaudited Pro Forma Financial Statements, the amount of
purchase cost allocated to goodwill and other intangibles is estimated to be
approximately U.S.$3.2 billion, including the related deferred tax effect. If
goodwill and other intangible assets were amortized in equal quarterly amounts
over a five year period following completion of the Transaction, the accounting
charge attributable to these items would be U.S.$161 million per quarter and
U.S.$643 million per fiscal year. As a result, purchase accounting treatment of
the Transaction will result in a net loss for JDS Uniphase in the foreseeable
future which could have a material and adverse effect on the market value of JDS
Uniphase common stock following completion of the Transaction. JDS' results of
operations will be included in Uniphase's consolidated results of operations
after the Effective Time. See "Risk Factors -- Purchase Accounting Treatment;
Impact of Amortization of Substantial Goodwill and Other Intangibles on
Operating Results".

STOCK EXCHANGE LISTINGS

EXCHANGEABLE SHARES

    The TSE has been notified of the proposed Arrangement and the TSE has
conditionally approved the listing of the Class B Non-Voting Preference Shares
and the listing of the Exchangeable Shares, subject to the satisfaction of the
customary requirements of the TSE. The Exchangeable Shares are being listed in
substitution for the JDS Common Shares which will be delisted on or after the
Effective Date. There is no current intention to list the Exchangeable Shares on
any other stock exchange.

UNIPHASE COMMON SHARES

    The Uniphase Common Shares, which will, after completion of the Transaction,
be the common shares of JDS Uniphase, are quoted on NASDAQ. Uniphase will apply
to NASDAQ to quote the Uniphase Common Shares issued pursuant to the Arrangement
or issuable from time to time in exchange for the Exchangeable Shares or upon
exercise of the Replacement Options.

ELIGIBILITY FOR INVESTMENT IN CANADA

    On the date of issue, the Class B Non-Voting Preference Shares, the
Exchangeable Shares and Exchangeable Share Rights will be eligible investments
under the following statutes (and, where applicable, the regulations
thereunder):

    INSURANCE COMPANIES ACT (Canada)

    PENSION BENEFITS STANDARDS ACT, 1985 (Canada)

    TRUST AND LOAN COMPANIES ACT (Canada)

    LOAN AND TRUST CORPORATIONS ACT (Ontario)

    PENSION BENEFITS ACT (Ontario)

subject to compliance with the prudent investment standards and general
investment provisions and restrictions of the statutes referred to above (and,
where applicable, the regulations thereunder) and, in certain cases, subject to
the satisfaction of additional requirements relating to investment or lending
policies or goals and, in certain cases, the filing of such policies or goals.

    Provided the Exchangeable Shares are listed on a prescribed stock exchange
in Canada (which currently includes the TSE), the Exchangeable Shares and
Exchangeable Share Rights will be qualified investments under the Canadian Tax
Act for trusts governed by RRSPs, RRIFs and DPSPs and under Tax Proposals would
be qualified investments for trusts governed by RESPs. Provided the Class B
Non-Voting Preference Shares are listed on a prescribed stock exchange in Canada
(which currently includes the TSE), the Class B Non-Voting Preference Shares
will be qualified investments for such plans under the Canadian Tax Act.
Uniphase Common Shares (including any related Uniphase Rights) will be qualified
investments under the Canadian Tax Act for such plans provided such shares
remain listed on NASDAQ (or are listed on another prescribed stock

                                      S-52

exchange). The Ancillary Rights will not be qualified investments under the
Canadian Tax Act. However, JDS' financial advisor, CIBC World Markets, is of the
view that the fair market value of such rights is nominal. Based on such view,
there should be no material consequences under the Canadian Tax Act to RRSPs,
RRIFs and DPSPs holding such non-qualified investments. RESPs holding such
non-qualified investments may, however, under Tax Proposals, realize adverse
consequences regardless of the fair market value of such non-qualified
investments.

    Provided the Exchangeable Shares are listed on a prescribed stock exchange
in Canada (which currently includes the TSE), the Exchangeable Shares and
Exchangeable Share Rights will not be foreign property under the Canadian Tax
Act for trusts governed by registered pension plans, RRSPs, RRIFs and DPSPs or
for certain other Persons to whom Part XI of the Canadian Tax Act is applicable.
Provided the Class B Non-Voting Preference Shares are listed on a prescribed
stock exchange in Canada (which currently includes the TSE), the Class B
Non-Voting Preference Shares will not be foreign property for such plans under
the Canadian Tax Act. The Ancillary Rights will be foreign property under the
Canadian Tax Act. However, JDS' financial advisor, CIBC World Markets, is of the
view that the fair market value of such rights is nominal. Uniphase Common
Shares (including any related Uniphase Rights) will be foreign property under
the Canadian Tax Act.

REGULATORY MATTERS

    Neither Uniphase nor JDS is aware of any material licenses or regulatory
permits that it holds which might be adversely affected by the Transaction or of
any material approval or other action by any federal, provincial, state or
foreign government or any administrative or regulatory agency that would be
required to be obtained prior to the Effective Date, except as described below.

INVESTMENT CANADA ACT

    The INVESTMENT CANADA ACT is Canada's statute of general application
governing the acquisition of control of Canadian businesses by non-Canadians.
Notwithstanding that the Transaction is a merger of equals, the Transaction is
considered to be an acquisition of control of a Canadian business by a
non-Canadian for purposes of the INVESTMENT CANADA ACT. A proposed acquisition
of a Canadian business by a non-Canadian prospective acquiror is subject to
prior review and approval by the Minister of Industry Canada (the "Minister") if
the value of the assets of the acquired business is equal to or greater than
Cdn.$184 million (for transactions that close in 1999). A reviewable investment
may not be completed until the Minister determines that the investment is likely
to be of "net benefit to Canada". The value of assets of JDS to be combined with
those of Uniphase through the Transaction exceeds Cdn.$184 million and the
Transaction is, therefore, reviewable.

    To commence the review process, Uniphase submitted an application with
prescribed information to the Director of Investments within Industry Canada on
February 15, 1999. On May 6, 1999, the Minister advised Uniphase that he was
satisfied that the investment would likely be of net benefit to Canada.

HSR ACT (UNITED STATES)

    Under the HSR Act and the rules promulgated thereunder by the FTC, certain
transactions, including the Transaction, may not be consummated unless
notification has been given and certain information has been furnished to the
FTC and the Antitrust Division and the specified waiting period requirements
have been satisfied. Uniphase and Furukawa, as a shareholder of JDS who may be
deemed an acquiror of Uniphase by virtue of its ownership of JDS Common Shares,
filed notification and report forms under the HSR Act with the FTC and the
Antitrust Division. The waiting period under the HSR Act began on March 25, 1999
and expired at 11:59 p.m., New York City time, on April 24, 1999.

    The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the Transaction. At any time before
or after the consummation of the Transaction, the Antitrust Division or the FTC
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the consummation
of the Transaction or seeking divestiture of substantial assets of Uniphase and
JDS. At any time before or after the consummation of the Transaction and
notwithstanding that the HSR Act waiting period expired, any state could take
such action under the state antitrust laws as it deems necessary or desirable in
the public interest. Such action could include seeking to

                                      S-53

enjoin the consummation of the Transaction or seeking divestiture of JDS or
businesses of Uniphase. Private parties may also seek to take legal action under
the antitrust laws under certain circumstances.

    Uniphase and JDS believe that the Transaction can be effected in compliance
with federal and state antitrust laws. However, there can be no assurance that a
challenge to the consummation of the Transaction on antitrust grounds will not
be made or that, if such a challenge were made, Uniphase and JDS would prevail
or would not be required to accept certain conditions, possibly including
certain divestitures, in order to consummate the Transaction.

RESALE OF EXCHANGEABLE SHARES AND UNIPHASE COMMON SHARES RECEIVED IN THE
  TRANSACTION

UNITED STATES

    The Class B Non-Voting Preference Shares, Exchangeable Shares and Uniphase
Common Shares to be issued to JDS Shareholders in the Transaction will not be
registered under the Securities Act. Such shares will instead be issued in
reliance upon the exemption provided by Section 3(a)(10) of the Securities Act.
Section 3(a)(10) exempts only securities issued in exchange for one or more BONA
FIDE outstanding securities from the general requirement of registration where
the terms and conditions of the issuance and exchange of such securities have
been approved by any court of competent jurisdiction, after a hearing upon the
fairness of the terms and conditions of the issuance and exchange at which all
persons to whom such securities will be issued have the right to appear. The
Court is authorized to conduct a hearing to determine the fairness of the terms
and conditions of the Arrangement, including the proposed issuance of securities
in exchange for other outstanding securities. The Court entered the Interim
Order on May 11 , 1999 and, subject to the approval of the Arrangement by the
JDS Shareholders, a hearing on the fairness of the Arrangement will be held on
or about June 30, 1999 by the Court. See "The Transaction -- Court Approval of
the Arrangement and Completion of the Transaction".

    The Exchangeable Shares and Uniphase Common Shares received in exchange for
JDS Common Shares in the Arrangement will be freely transferable under U.S.
federal securities laws, except for Exchangeable Shares and Uniphase Common
Shares held by persons who are deemed to be "affiliates" (as such term is
defined under the Securities Act) of JDS or Uniphase prior to the Transaction,
which may be resold by them only in transactions permitted by the resale
provisions of Rule 145(d)(1), (2), or (3) under the Securities Act or as
otherwise permitted under the Securities Act. Rule 145(d)(1) generally provides
that "affiliates" of either JDS or Uniphase may not sell securities of Uniphase
received in the Arrangement unless such sale is effected pursuant to an
effective registration statement or pursuant to the volume, current public
information, manner of sale and timing limitations set forth in paragraphs (c),
(e), (f) and (g) of Rule 144 under the Securities Act. These limitations
generally require that any sales made by an affiliate in any three-month period
shall not exceed the greater of 1% of the outstanding shares of the securities
being sold or the average weekly trading volume over the four calendar weeks
preceding the placement of the sell order and that such sales be made in
unsolicited, open market "brokers' transactions". Persons who may be deemed to
be affiliates of an issuer generally include individuals or entities that
control, are controlled by, or are under common control with, such issuer and
may include certain officers and directors of such issuer as well as principal
shareholders of such issuer. Rules 145(d)(2) and (3) generally provide that the
foregoing limitations lapse for non-affiliates of Uniphase after a period of one
or two years, respectively, from the date of share issuances, depending upon
whether certain currently available information continues to be available with
respect to Uniphase.

    Uniphase has agreed to file a registration statement on Form S-3 prior to
the Effective Time in order to register under the Securities Act the Uniphase
Common Shares to be issued from time to time in exchange for the Exchangeable
Shares or upon the exercise of Replacement Options. It is a condition to the
obligation of JDS to complete the Transaction that such registration statement
shall have been declared effective by the SEC prior to the Effective Time. See
"The Merger Agreement -- Conditions to Closing".

    Following completion of the Transaction, Furukawa, which will, immediately
following the Transaction, hold approximately 24% of the outstanding Uniphase
Common Shares and Exchangeable Shares, taken together, will be considered an
affiliate under the Securities Act. As consideration for the execution of the
Furukawa Support Agreement, Uniphase and Exchangeco have agreed pursuant to the
Furukawa Registration Rights Agreement, among other things, to register Uniphase
Common Shares under the Securities Act, on the request of Furukawa

                                      S-54

or a subsidiary of Furukawa in certain circumstances. See "The
Transaction -- Furukawa Support Agreement" and "The Companies after the
Transaction -- Principal Holders of Securities".

CANADA

    Uniphase and Exchangeco will apply for rulings or orders of certain
securities regulatory authorities in Canada to permit the issuance of the Class
B Non-Voting Preference Shares, the Exchangeable Shares and the Uniphase Common
Shares issuable under the Arrangement, upon exchange of Exchangeable Shares and
upon exercise of Replacement Options. Application has also been made or will be
made to permit resale of those shares in various jurisdictions without
restriction by Persons other than a "control person", provided that no unusual
effort is made to prepare the market for any such resale or to create a demand
for the securities which are the subject of any such resale and no extraordinary
commission or consideration is paid in respect thereof. The consummation of the
Transaction is conditional upon the receipt of such rulings or orders.

ONGOING CANADIAN REPORTING OBLIGATIONS

    Upon completion of the Arrangement, JDS will be an indirect wholly-owned
subsidiary of JDS Uniphase. Accordingly, after the Effective Date, JDS will
apply to the securities regulatory authorities in Canada to cease to be a
reporting issuer.

    Exchangeco, upon completion of the Arrangement, will be a reporting issuer
in certain of the Canadian provinces and territories. Applications will be made
for certain exemptions from statutory financial and reporting requirements,
including an exemption for insiders of Exchangeco from the requirement to file
reports with respect to trades of Exchangeco securities, in those Canadian
provinces and territories on the condition that, following completion of the
Transaction, JDS Uniphase files with the relevant securities regulatory
authorities copies of certain of its reports filed with the SEC and that holders
of Exchangeable Shares receive certain materials that are sent to holders of
Uniphase Common Shares, including annual and interim financial statements of JDS
Uniphase and shareholder meeting materials. Reports filed by insiders of JDS
Uniphase with the SEC will disclose beneficial ownership of Uniphase Common
Shares and Exchangeable Shares.

    After the Effective Time and subject to Exchangeco receiving the
above-described reporting exemptions, holders of Exchangeable Shares will
receive annual and interim financial statements of JDS Uniphase prepared in
accordance with U.S. GAAP in lieu of financial statements of Exchangeco.

ARRANGEMENTS RESPECTING OPTIONS

    On May 14, 1999, there were JDS Options outstanding which, when vested,
would be exercisable to acquire a total of approximately 4,300,847 JDS Common
Shares at prices between Cdn.$0.82 to Cdn.$92.00 with various expiry dates to
May, 2006. In addition, Uniphase will grant additional options in respect of an
aggregate of 4,110,260 Uniphase Common Shares effective at the Effective Time to
be allocated to those employees of JDS designated by the Chief Executive Officer
of JDS with the prior approval of the compensation committee of JDS. The
exercise price for such JDS Uniphase options shall be equal to the closing price
of the Uniphase Common Shares on NASDAQ on the Effective Date.

    At the Effective Time, each JDS Option will become a Replacement Option.
Each Replacement Option will constitute an option to purchase a number of
Uniphase Common Shares equal to the product of the Exchange Ratio and the number
of JDS Common Shares subject to such JDS Option. Such Replacement Option will
provide for an exercise price per Uniphase Common Share equal to the exercise
price per share of such JDS Option immediately prior to the Effective Time
divided by the Exchange Ratio and converted into U.S. dollars based on the Noon
Buying Rate on the Effective Date. If the foregoing calculation results in a
Replacement Option being exercisable for a fraction of a Uniphase Common Share,
then the number of Uniphase Common Shares subject to such Replacement Option
shall be rounded down to the next whole Uniphase Common Share and the total
exercise price for the Replacement Option will be reduced by the exercise price
of the fractional Uniphase Common Share. The term to expiry, conditions to and
manner of exercising and all other terms and conditions of such Replacement
Option will otherwise be unchanged from those of the JDS Option except that,
immediately prior to the Effective Time the Compensation Committee of the JDS
Board of Directors may resolve to accelerate the vesting schedule for all or a
portion of the JDS Options such that, immediately following the Effective Time,
the corresponding Replacement Options (in respect of up to an anticipated

                                      S-55

maximum of 2,000,000 Uniphase Common Shares) will be immediately exercisable.
The extent to which any particular optionholder's JDS Options are accelerated
will be determined based on the optionholder's performance, responsibility and
length of service. The vesting schedule of certain unvested Replacement Options
will be amended to conform to the vesting schedule of the Uniphase 1993 Plan to
the extent that the vesting schedule contained in the Uniphase 1993 Plan is more
beneficial to the optionholder than the existing JDS Option vesting schedule.
Any document or agreement previously evidencing a JDS Option shall thereafter
evidence and be deemed to evidence such Replacement Option.

FUTURE ISSUANCES OF SHARES

    The Exchangeco articles of incorporation will be amended to authorize the
issuance of an unlimited number of Exchangeable Shares. The Exchangeable Shares
that will be authorized may be issued, without approval of holders of
Exchangeable Shares, at such time or times, to such Persons and for such
consideration as Exchangeco may determine, except as may otherwise be required
by applicable laws, regulations or stock exchange requirements, and subject to
all dividends on the outstanding Exchangeable Shares corresponding to dividends
declared and paid on the outstanding Uniphase Common Shares having been declared
and paid at the relevant times. The TSE, on which it is anticipated that the
Exchangeable Shares will trade, currently requires shareholder approval of
certain transactions resulting in the issuance of shares, including transactions
where the issuance could increase the number of outstanding shares by 25% or
more.

    In addition, at the Uniphase Meeting, the Uniphase Stockholders will be
asked to approve a proposal to amend the Uniphase Charter to increase the
aggregate number of Uniphase Common Shares which Uniphase is authorized to issue
from 100,000,000 to 200,000,000 shares.

EXPENSES

    The combined estimated fees, costs and expenses of Uniphase and JDS in
connection with the Transaction including, without limitation, financial
advisors' fees, filing fees, legal and accounting fees, soliciting dealer fees
and printing and mailing costs are anticipated to be approximately U.S.$12
million. These expenses are referred to in Note 1 to the JDS Uniphase unaudited
pro forma consolidated condensed statements of operations and have been
reflected in the JDS Uniphase unaudited pro forma consolidated condensed balance
sheet included herein. See "JDS Uniphase Unaudited Pro Forma Financial

(1) In November 1998, Uniphase acquired Uniphase Broadband Products, Inc.
    ("UBP") in a transaction accounted for as a pooling of interests. UBP was a
    Subchapter S Corporation for income tax purposes prior to acquisition,
    therefore its taxable income was includable in the personal income tax
    returns of its stockholders. UBP made periodic dividend distributions to its
    pre-merger stockholders based on their estimated tax liability on the
    earnings of UBP. Uniphase has not paid cash dividends on the Uniphase Common
    Shares.

(2) Subsequent to the SEC's letter to the American Institute of Certified Public
    Accountants dated September 9, 1998, regarding its views on in-process
    research and development, Uniphase re-evaluated its in-process research and
    development charge with respect to its acquisition of Uniphase Netherlands
    B.V. in June 1998, revised the purchase price allocation and restated its
    financial statements. As a result, Uniphase made an adjustment which
    decreased the amount of previously expensed in-process research and
    development, increased the amount capitalized as goodwill and other
    intangibles and decreased the net loss by U.S.$59.3 million and decreased
    basic and diluted net loss per share by U.S.$1.68 for the year ended June
    30, 1998.

(1) For Canadian GAAP purposes, unrealized gains and losses on foreign exchange
    contracts related to anticipatory transactions are not recognized until
    realized. Under U.S. GAAP, gains and losses on such foreign exchange
    contracts are recognized in the period that the exchange rates change. See
    Note 17 to the JDS Audited Financial Statements included in Appendix L to
    this Supplement. JDS has not paid dividends on the JDS Common Shares.

(2) For Canadian GAAP, the dilutive effect of stock options is calculated using
    the imputed income method. Under U.S. GAAP, the treasury stock method is
    used to compute the dilutive effect of stock options.

             JDS UNIPHASE UNAUDITED PRO FORMA FINANCIAL STATEMENTS

    The JDS Uniphase Unaudited Pro Forma Financial Statements give effect to the
combination of Uniphase and JDS through the issuance of Uniphase Common Shares
and the Exchangeable Shares for the outstanding JDS Common Shares. The unaudited
pro forma statements of operations for the year ended June 30, 1998 and for the
nine months ended March 31, 1999 reflect the combination as if it had taken
place on July 1, 1997. The unaudited pro forma consolidated combined condensed
balance sheet gives effect to the combination as if it had taken place on March
31, 1999. The unaudited pro forma consolidated combined condensed statements of
operations combine Uniphase's historical results of operations for the year
ended June 30, 1998 and the nine months ended March 31, 1999 with JDS'
historical results of operations for the year ended May 31, 1998 and the nine
months ended February 28, 1999, respectively.

    The JDS Uniphase Unaudited Pro Forma Financial Statements reflect the
combination using the purchase method of accounting and have been prepared on
the basis of assumptions described in the notes thereto, including assumptions
relating to the allocation of the total purchase cost to the assets and
liabilities of JDS based upon preliminary estimates of their fair value. The
actual allocation may differ from those assumptions after valuations and other
procedures to be performed after the completion of the Transaction are
finalized.

    The JDS Uniphase Unaudited Pro Forma Financial Statements should be read in
conjunction with the Uniphase Audited Financial Statements, the Uniphase
Unaudited Financial Statements, the JDS Audited Financial Statements and the JDS
Unaudited Financial Statements, all of which are appended to this document. The
JDS Uniphase Unaudited Pro Forma Financial Statements are not necessarily
indicative of what the actual operating results or financial position would have
been had the combination actually taken place on July 1, 1997 or March 31, 1999
and do not purport to indicate JDS Uniphase's future results of operations.

         NOTES TO JDS UNIPHASE UNAUDITED PRO FORMA FINANCIAL STATEMENTS

1.  BASIS OF PRO FORMA PRESENTATION

    The JDS Uniphase Unaudited Pro Forma Financial Statements reflect the
    issuance of 39,750,920 Uniphase Common Shares or Exchangeable Shares for all
    of the outstanding JDS Common Shares based on the outstanding JDS Common
    Shares as of February 28, 1999, the Exchange Ratio of 0.50855 of a Uniphase
    Common Shares or 0.50855 of an Exchangeable Share for each JDS Common Share
    and an average market price per Uniphase Common Share of U.S.$81.713 per
    share. The average market price per Uniphase Common Share is based on the
    average closing price for a range of trading days (January 22 through
    February 4, 1999) around the announcement date (January 28, 1999) of the
    Transaction. The actual number of Uniphase Common Shares and Exchangeable
    Shares to be issued will depend on the actual number of outstanding JDS
    Common Shares at the Effective Time. In addition, Uniphase will issue
    options to purchase Uniphase Common Shares in exchange for outstanding JDS
    Options with the number of shares and the exercise price appropriately
    adjusted by the Exchange Ratio. Based on the total outstanding JDS Options
    as of February 28, 1999, Uniphase would issue options to purchase 2,320,440
    Uniphase Common Shares at a weighted average exercise price of U.S.$8.29 per
    share. The actual number of options granted will depend on the actual number
    of JDS Options outstanding at the Effective Time. The value of the options,
    as well as estimated direct transaction expenses of U.S.$12 million, have
    been included as a part of the total estimated purchase cost.

    The JDS Uniphase Unaudited Pro Forma Financial Statements have been prepared
    on the basis of assumptions relating to the allocation of the total purchase
    cost to the assets and liabilities of JDS based upon preliminary estimates
    of their fair value. The actual allocation of the total purchase cost may
    differ from those assumptions after valuations and other procedures to be
    completed after the closing of the Transaction. Following is a table of the
    estimated total purchase cost and annual amortization of the intangible
    assets acquired (in thousands of U.S. dollars).

    Tangible net assets of JDS principally include cash and cash equivalents,
    short-term investments, accounts receivable, inventories and fixed assets.
    Liabilities assumed principally include accounts payable, accrued
    compensation and other accrued expenses.

    In estimating the value of the trademark and tradename, the relief from
    royalty method was employed. The relief from royalty method is based on the
    assumption that in lieu of ownership, a firm would be willing to pay a
    royalty in order to exploit the related benefits of the asset. Therefore, a
    portion of the company's earnings, equal to the after-tax royalty that would
    have been paid for the use of the trademark and tradename, can be attributed
    to the firm's possession of the trademark and tradename. The trademark and
    tradename are each being amortized on a straight-line basis over its
    estimated useful life of five years.

    The value of the assembled workforce was derived by estimating the costs to
    replace the existing employees, including recruiting, hiring and training
    costs for each category of employee. The value of the assembled workforce is
    being amortized on a straight line basis over its estimated useful life of
    five years.

    A portion of the purchase price has been allocated to developed technology
    and IPRD. Developed technology and IPRD were identified and valued through
    extensive interviews, analysis of data provided by JDS concerning
    developmental products, their stage of development, the time and resources
    needed to complete them, if applicable, their expected income generating
    ability, target markets and associated risks. The Income Approach, which
    includes an analysis of the markets, cash flows, and risks associated with
    achieving such cash flows, was the primary technique utilized in valuing the
    developed technology and IPRD.

                            JDS UNIPHASE CORPORATION

   NOTES TO JDS UNIPHASE UNAUDITED PRO FORMA FINANCIAL STATEMENTS (CONTINUED)

1.  BASIS OF PRO FORMA PRESENTATION (CONTINUED)
    Where developmental projects had reached technological feasibility, they
    were classified as developed technology and the value assigned to developed
    technology was capitalized. The developed technology is being amortized on
    the straight-line basis over its estimated useful life of five years. Where
    the developmental projects had not reached technological feasibility and had
    no future alternative uses, they were classified as IPRD. The value
    allocated to projects identified as IPRD will be charged to expense upon
    closing of the Transaction. Such amount has been reflected in the JDS
    Uniphase unaudited pro forma consolidated condensed balance sheet but has
    not been reflected in the JDS Uniphase unaudited pro forma consolidated
    condensed statements of operations since such amount is non-recurring in
    nature. The nature of the efforts required to develop the purchased IPRD
    into commercially viable products principally relate to the completion of
    all planning, designing, prototyping, verification and testing activities
    that are necessary to establish that the products can be produced to meet
    their design specifications, including functions, features and technical
    performance requirements.

    In valuing the IPRD, Uniphase considered, among other factors, the
    importance of each project to the overall development plan, the projected
    incremental cash flows from the projects when completed and any associated
    risks. The projected incremental cash flows were discounted back to their
    present value using a discount rate of 27%. This discount rate was
    determined after consideration of Uniphase's weighted average cost of
    capital and the weighted average return on assets. Associated risks include
    the inherent difficulties and uncertainties in completing each project and
    thereby achieving technological feasibility, anticipated levels of market
    acceptance and penetration, market growth rates and risks related to the
    impact of potential changes in future target markets.

    The IPRD relates to sophisticated optical components and modules that manage
    light transmission through today's most advanced telecommunications systems.
    The IPRD is comprised of four main categories: (i) Thermo Optic Waveguide
    Attenuators, (ii) Solid State Switch, (iii) 50 GHz Wavelength Division
    Multiplexing ("WDM"), and (iv) Erbium Doped Fiber Amplifiers ("EDFA").

    The following is a brief description of each acquired in-process research
    and development project at the anticipated Effective Date:

    THERMO-OPTIC WAVEGUIDE ATTENUATOR.  The main application for this product is
    in active power control for optical networks, both at the transmitter for
    pre-emphasis and inside an optical amplifier for gain tilt control. The
    current generation of attenuators are optomechanical but the thermo-optic
    attenuator will be solid state. The main advantages of this technology are:
    no moving parts, smaller size, and lower cost.

    SOLID STATE SWITCH.  This is the waveguide optical switch series of solid
    state switches. This technology uses the thermo-optic effect in a polymer.
    The main application is in configurable optical add/drop and optical
    protection switching.

    50GHZ WDM.  This product represents the next generation of WDM components.
    These products are used by telecommunications carriers to enhance the
    carrying capacity of fiber in their long-distance networks.

    EDFA.  The EDFA is used to compensate for fiber loss and extends the reach
    of the telecommunication system on which it is being used. In WDM systems,
    all the wavelengths can be amplified by a single EDFA. This method is much
    more cost effective than using electrical regenerators for individual
    wavelengths.

    With respect to the acquired in-process technologies, the calculations of
    value were adjusted to reflect the value creation efforts of JDS prior to
    the Effective Date. Following are the estimated completion percentages and
    technology lives:

    THERMO-OPTIC WAVEGUIDE ATTENUATOR.  Uniphase estimates that the development
    cycle for this product family will continue for approximately 18 months
    subsequent to the expected date of completion of the Transaction. The
    product is currently in the designing stage of the development cycle. The
    estimated cost to complete development of the attenuator technology is
    expected to be approximately U.S.$1.0 million ratably until its completion
    in the third calendar quarter of 2000. Uniphase believes the associated
    risks of developing this product into commercially viable products to be
    meeting customer/market performance specifications and competing
    technologies that offer comparable functionality.

    SOLID STATE SWITCH.  Uniphase estimates that the development cycle for this
    product family will continue for approximately 12 months subsequent to the
    expected date of completion of the Transaction. The product is currently in
    the prototyping stage of the development cycle. The estimated cost to
    complete development of the switching technology is expected to be
    approximately U.S.$1.8 million ratably

    until its completion in the first calendar quarter of 2000. Uniphase
    believes the associated risks of developing this product into commercially
    viable products to be meeting customer/market performance specifications and
    competing technologies that offer comparable functionality.

    50GHZ WDM.  Uniphase estimates that the development cycle for this product
    family will continue for approximately 9 months subsequent to the expected
    date of completion of the Transaction. The product is currently in the
    verification and testing stage of the development cycle. The estimated cost
    to complete development of the 50GHz WDM technology is expected to be
    approximately U.S.$5.0 million ratably until its completion in the first
    calendar quarter of 2000. Uniphase believes the associated risks of
    developing this product into commercially viable products to be meeting
    customer/market performance specifications and competing technologies that
    offer comparable functionality.

    EDFA.  Uniphase estimates that the development cycle for this product family
    will continue for approximately 3 months subsequent to the expected date of
    completion of the Transaction. The product is currently in the verification
    and testing stage of the development cycle. The estimated cost to complete
    development of the EDFA technology is expected to be approximately U.S.$4.1
    million ratably until its completion in the third calendar quarter of 1999.
    Uniphase believes the associated risks of developing this product into
    commercially viable products to be meeting customer/market performance
    specifications and competing technologies that offer comparable
    functionality.

    Goodwill is determined based on the residual difference between the amount
    paid and the values assigned to identified tangible and intangible assets.
    Goodwill is being amortized on a straight line basis over its estimated
    useful life of five years.

2.  PRO FORMA NET LOSS PER SHARE

    The JDS Uniphase unaudited pro forma consolidated condensed statements of
    operations have been prepared as if the combination of Uniphase and JDS had
    occurred on July 1, 1997. The pro forma basic and dilutive net loss per
    share are based on the weighted average number of Uniphase Common Shares
    outstanding during each period and the weighted average number of JDS Common
    Shares outstanding during each period multiplied by the Exchange Ratio. The
    Replacement Options are not included in the computation of pro forma
    dilutive net loss per share as their effect would be antidilutive.

3.  PRO FORMA ADJUSTMENTS

    The JDS Uniphase Unaudited Pro Forma Financial Statements give effect to the
    allocation of the total purchase cost to the assets and liabilities of JDS
    based on their relative fair values and to the amortization over the
    respective useful lives of amounts allocated to intangible assets.

    Intercompany transactions between Uniphase and JDS were insignificant.

    The pro forma income tax adjustments represent a deferred tax liability, and
    the related amortization, resulting from the book and tax basis difference
    of the indentified intangible assets acquired.

4.  CONVERSION OF JDS FINANCIAL INFORMATION TO U.S. GAAP AND U.S.$

    The financial statements of JDS, which were prepared in accordance with
    Canadian GAAP, have been conformed to U.S. GAAP for purposes of including
    them in the JDS Uniphase Unaudited Pro Forma Financial Statements. None of
    the adjustments necessary to conform the financial statements of JDS to U.S.
    GAAP were material to either the historical financial statements of JDS or
    the JDS Uniphase Unaudited Pro Forma Financial Statements. Other than the
    adjustments necessary to conform to U.S. GAAP, no other adjustments were
    necessary to conform the financial statements of JDS with Uniphase's
    accounting policies. The balance sheet and statements of operations for JDS
    were translated to U.S.$ using historical period-end exchange rates for the
    JDS Uniphase unaudited pro forma consolidated condensed balance sheet and
    historical average exchange rates for the periods reflected in the JDS
    Uniphase

(1) Because of different year ends, consolidated financial information relating
    to Uniphase's fiscal year ended June 30, 1998 and nine months ended March
    31, 1999 has been combined with financial information for JDS for the fiscal
    year ended May 31, 1998 and nine months ended February 28, 1999,
    respectively.

(2) The historical book value per share is computed by dividing total
    stockholders' equity as of the end of each period for which such computation
    is made by the number of common shares outstanding at the end of each
    period.

(3) The pro forma book value per share is computed by dividing pro forma
    stockholders' equity by the pro forma number of shares outstanding at the
    end of each period for which such computation is made. For purposes of
    computing pro forma book value per share as of June 30, 1998 the pro forma
    book value of U.S.$3.6 billion was divided by pro forma common shares
    outstanding of 78.7 million.

(4) The JDS pro forma equivalent per share amounts are computed by multiplying
    the JDS Uniphase pro forma combined per share amounts by the Exchange Ratio
    of 0.50855 of a Uniphase Common Share or 0.50855 of an Exchangeable Share
    for each JDS Common Share. Pro forma diluted earnings per share excludes the
    effect of dilutive securities totalling 4,326,000 and 1,187,000 equivalent
    shares for the nine months ended March 31, 1999 and the year ended June 30,
    1998, respectively, as they are antidilutive.

                                      S-73

    On January 27, 1999, the last full trading day prior to the public
announcement of the Transaction, the closing sale price per Uniphase Common
Share, as reported on NASDAQ, was U.S.$77.125, and the closing sale price per
JDS Common Share as reported on the TSE was Cdn.$53.50. On May 13, 1999, the
last trading day prior to the date of this Supplement, the closing sale price
per Uniphase Common Share as reported on NASDAQ was U.S.$137.375, and the
closing sale price per JDS Common Share as reported on the TSE was Cdn.$100.00.

    Because the market price of Uniphase Common Shares is subject to fluctuation
due to numerous market forces, the market value of the Uniphase Common Shares
that holders of JDS Common Shares will receive pursuant to the Transaction or
upon exchange of the Exchangeable Shares may increase or decrease prior to the
Effective Time. Shareholders are urged to obtain current market quotations for
their shares and the Uniphase Common Shares. Historical market prices are not
indicative of future market prices.

    Neither Uniphase nor JDS has paid cash or other dividends in the last three
years (other than, in the case of Uniphase, the distribution of Uniphase Rights
described under the heading "Uniphase Capital Stock -- Uniphase Rights
Agreement"). Neither Uniphase nor JDS anticipates the declaration of cash
dividends prior to the Effective Time. See "The Companies after the
Transaction -- Dividend Policy".

                              THE MERGER AGREEMENT

    The following is a summary of the material terms of the Merger Agreement.
JDS Shareholders and Uniphase Stockholders are urged to read the Merger
Agreement in its entirety which is attached as Appendix A to this Supplement.

REPRESENTATIONS AND WARRANTIES

    The Merger Agreement contains certain customary representations and
warranties of each of the Uniphase Parties and JDS relating to, among other
things, their due incorporation and their respective organization,
capitalization, operations, financial condition, Year 2000 compliance,
intellectual property rights, employees, and other matters, including their
authority to enter into the Merger Agreement and to consummate the Transaction.

COVENANTS

    Pursuant to the Merger Agreement, each Uniphase Party and JDS has agreed
that, among other things, until the earlier of the termination of the Merger
Agreement and the Effective Date, except as expressly contemplated by the Merger
Agreement, or with the prior written consent of the other parties, it will:

    (i) conduct its business only in, and cause its respective subsidiaries to,
        and not take any action except in, the usual, ordinary course of
        business consistent with past practice and use its, and cause each of
        its subsidiaries to use, commercially reasonable efforts to preserve
        intact their respective present business organizations and goodwill, to
        keep available the services of their present officers and employees and
        to maintain satisfactory relationships with suppliers, agents,
        distributors, customers and others having business dealings with it or
        its subsidiaries;

    (ii) not allot, reserve, set aside or issue, authorize or propose the
         allotment, reservation, setting aside or issuance of any shares in its
         capital stock or of any subsidiary thereof, or any securities
         convertible or exchangeable into, or rights, warrants or options to
         acquire any such shares, subject to certain exceptions, including the
         issuance of up to 100,000 Uniphase Common Shares pursuant to the
         Uniphase 1998 Employee Stock Purchase Plan;

   (iii) not amend or propose to amend its articles or by-laws except, in the
         case of Uniphase, to propose to Uniphase Stockholders at the Uniphase
         Meeting to change its name to JDS Uniphase Corporation, to increase the
         authorized capital of Uniphase from 100,000,000 Uniphase Common Shares
         to 200,000,000 Uniphase Common Shares and to increase the number of
         Uniphase Common Shares reserved for issuance pursuant to the Uniphase
         1998 Employee Stock Purchase Plan; and, in the case of Exchangeco, to
         amend its articles to change its name and registered office, to
         authorize an unlimited number of Exchangeable Shares and Class B
         Non-Voting Preference Shares and 10,000 Class A

                                      S-74

         Non-Voting Preference Shares and to delete the "private company"
         restrictions contained in its articles;

    (iv) not split, combine or reclassify any of its outstanding common shares
         or declare, set aside or pay any dividends on or make any other
         distributions on or in respect of its outstanding shares;

    (v) not purchase, redeem or offer to purchase any common shares or any
        shares or securities convertible or exchangeable into common shares,
        unless otherwise permitted or required by the terms of such securities;

    (vi) not authorize, propose or agree to acquire or dispose of, any
         businesses, assets or securities, the value of the consideration for
         which acquisition or disposition (including assumed debt or other
         obligations) would exceed U.S.$5 million (including in a series of
         related transactions);

   (vii) promptly advise the other parties orally and, if then requested, in
         writing of: (A) any Material Adverse Change or any event which would
         reasonably be expected to become a Material Adverse Change, in respect
         of its or any of its subsidiaries' businesses; and (B) any material
         Governmental Entity's or third party complaints, investigations or
         hearings (or communications indicating that the same may be
         contemplated);

  (viii) not settle or compromise any claim brought by any present, former or
         purported holder of any of its securities in connection with the
         Transaction;

    (ix) continue to provide to the other parties and their representatives
         information as reasonably requested by them from time to time
         concerning its business, assets, liabilities and affairs and with
         access (on a basis that does not detract unreasonably from the
         performance of its business responsibilities) to its management and
         employees and the management and employees of its subsidiaries;

    (x) use its reasonable efforts to comply promptly with all requirements
        which applicable laws may impose on it or its subsidiaries with respect
        to the Transaction; and

    (xi) use its, and cause its subsidiaries to use their, commercially
         reasonable efforts to perform all obligations and take all acts and do
         all things required or desirable either under the Merger Agreement or
         to consummate the Transaction and it will not take any action or
         refrain from taking any action that would be inconsistent with the
         Merger Agreement or which would reasonably be expected to significantly
         impede the consummation of the Transaction, including the use of all
         commercially reasonable efforts (A) to obtain the approval of its
         respective shareholders to the Arrangement or the Uniphase Transaction
         Proposal, as the case may be (subject to the exercise of the respective
         boards of directors of their fiduciary duties), and (B) to hold the
         Uniphase Meeting and the JDS Meeting on the same day.

    In addition, Uniphase has agreed in the Merger Agreement to use all
reasonable efforts to:

    (i) cause the Class B Non-Voting Preference Shares and the Exchangeable
        Shares to be created;

    (ii) cause the Class B Non-Voting Preference Shares to be listed and posted
         for trading on the TSE, by the Effective Date;

   (iii) cause the Exchangeable Shares to be listed and posted for trading on
         the TSE by the Effective Date;

    (iv) ensure that Exchangeco remains a "public corporation" (within the
         meaning of the Canadian Tax Act) for so long as there are Exchangeable
         Shares outstanding (other than those Exchangeable Shares held by
         Uniphase or its affiliates); and

    (v) reserve sufficient Uniphase Common Shares for issuance upon the
        Arrangement, the exchange from time to time of the Exchangeable Shares
        and the exercise from time to time of the Replacement Options.

                                      S-75

COVENANTS REGARDING NON-SOLICITATION

    Pursuant to the Merger Agreement, each of Uniphase and JDS has agreed that
it shall not, directly or indirectly, through any officer, director, employee,
representative, financial advisor or agent of Uniphase or JDS, as the case may
be, or any of its respective subsidiaries:

    (i) solicit, initiate or knowingly encourage (including by way of furnishing
        information or entering into any form of agreement, arrangement or
        understanding) the initiation of any Acquisition Proposal or inquiries
        or proposals in connection therewith;

    (ii) participate in any discussions or negotiations regarding any
         Acquisition Proposal;

   (iii) withdraw or modify the approval of the Uniphase Board of Directors or
         the JDS Board of Directors, as the case may be, of the Transaction in a
         manner adverse to the other;

    (iv) approve or recommend any Acquisition Proposal; or

    (v) cause Uniphase or JDS, as the case may be, to enter into any agreement
        related to any Acquisition Proposal.

Notwithstanding the foregoing, the Uniphase Board of Directors or the JDS Board
of Directors, as the case may be, may consider, negotiate, approve, recommend or
enter into an agreement in respect of a Superior Proposal. Uniphase and JDS must
notify each other of all Acquisition Proposals.

    If Uniphase or JDS receives a request for material non-public information
from a Person proposing a BONA FIDE Acquisition Proposal (the existence and
content of which shall have been disclosed to the other party) that the Uniphase
Board of Directors or the JDS Board of Directors, as the case may be, determines
is likely to be a Superior Proposal, then, subject to the execution by such
Person of a non-disclosure agreement containing a standstill provision
substantially on the terms referred to under the heading "Mutual Standstill"
below, Uniphase or JDS will be entitled to provide such information to such
Person.

    Uniphase and JDS have each agreed not to accept, approve, recommend or enter
into any agreement in respect of an Acquisition Proposal (other than a
non-disclosure agreement referred to above) on the basis that it would
constitute a Superior Proposal unless:

    (i) it has provided the other party with a copy of the Acquisition Proposal
        document which the board of directors of the recipient of the
        Acquisition Proposal has determined would be a Superior Proposal; and

    (ii) five Business Days shall have elapsed from the later of the date the
         other party received notice of the recipient's proposed determination
         to accept, approve, recommend or enter into an agreement in respect of
         such Acquisition Proposal, and the date the other party received a copy
         of the Acquisition Proposal.

    During such five Business Day period, the other party may, but is not
obligated to, offer to amend the terms of the Merger Agreement and the
Arrangement. The board of directors of the recipient of the Acquisition Proposal
will review any offer by the other party to amend the terms of the Merger
Agreement in good faith in order to determine, in its discretion in the exercise
of its fiduciary duties, whether the other party's offer upon acceptance by the
recipient would result in the Acquisition Proposal no longer being a Superior
Proposal. If the board of directors of the recipient so determines, it will
enter into an amended agreement with the other party reflecting the amended
proposal. If the board of directors of the recipient continues to believe, in
good faith and after consultation with its financial advisors and outside
counsel, that the Acquisition Proposal is nonetheless a Superior Proposal and
therefore rejects the other party's amended proposal, the recipient will pay to
the other party the Break Fee in two equal instalments; provided that the second
instalment is only payable in certain circumstances. See "The Merger
Agreement -- Termination and Payment of Break Fees and Expenses".

                                      S-76

MUTUAL STANDSTILL

    Until the earlier of the Effective Date and the termination of the Merger
Agreement, each of Uniphase and JDS has agreed that, except pursuant to the
Merger Agreement, it will not without the prior approval of the other:

    (i) in any manner acquire, agree to acquire or make any proposal or offer to
        acquire, directly or indirectly, any securities or property of the
        other;

    (ii) propose or offer to enter into, directly or indirectly, any merger or
         business combination involving the other or to purchase, directly or
         indirectly, a material portion of the assets of the other;

   (iii) directly or indirectly, solicit, or participate or join with any Person
         in the solicitation of, any proxies to vote, to seek to advise or to
         influence any Person with respect to the voting of any voting
         securities of the other, other than soliciting proxies or otherwise
         influencing any Person to vote in favour of the Uniphase Transaction
         Proposal at the Uniphase Meeting or the Arrangement at the JDS Meeting;

    (iv) otherwise act alone or in concert with others to seek to control or to
         influence the management, board of directors or policies of the other;

    (v) make any public or private disclosure of any consideration, intention,
        plan or arrangement inconsistent with any of the foregoing; or

    (vi) advise, assist or encourage any of the foregoing or work in concert
         with others in respect of the foregoing.

CONDITIONS TO CLOSING

MUTUAL CONDITIONS

to complete the Transaction are subject to the satisfaction or waiver, where

        Uniphase Meeting by the required vote of the Uniphase Stockholders;

    (iv) there shall not be in force any order or decree of a Governmental
         Entity restraining or enjoining the consummation of the Transaction and
         there shall be no proceeding (other than an appeal made in connection
         with the Arrangement), of a judicial or administrative nature or
         otherwise, in progress or threatened that relates to or results from
         the transactions contemplated by the Merger Agreement that would, if
         successful, result in an order or ruling that would preclude completion
         of the Transaction in accordance with the terms of the Merger Agreement
         or would otherwise be inconsistent with the regulatory approvals which
         have been obtained;

    (v) the Merger Agreement shall not have been terminated; and

    (vi) the Class B Non-Voting Preference Shares and the Exchangeable Shares
         issuable pursuant to the Arrangement shall have been conditionally
         approved for listing on the TSE, each subject to the filing of required
         documentation, and the Uniphase Common Shares issuable pursuant to the
         Arrangement, upon exchange of the Exchangeable Shares from time to time
         and upon exercise of the Replacement Options from time to time shall
         have been approved for quotation on NASDAQ, subject to notice of
         issuance.

    (ii) between January 28, 1999 and the Effective Date, there shall not have

         Adverse Change to JDS;

   (iii) certain regulatory approvals shall have been obtained and shall be in
         full force and effect and shall not be the subject of any stop-order or

    (ii) between January 28, 1999 and the Effective Date, there shall not have
         occurred, in the judgment of JDS, acting reasonably, a Material Adverse
         Change to Uniphase;

   (iii) certain regulatory approvals shall have been obtained and shall be in
         full force and effect and shall not be the subject of any stop-order or
         proceedings seeking a stop-order or any revocation proceedings;

    (iv) the Uniphase Board of Directors shall have granted options in respect
         of an aggregate of 4,110,260 Uniphase Common Shares effective at the
         Effective Time to be allocated to those employees of JDS designated by
         the Chief Executive Officer of JDS with the approval of the
         compensation committee of the JDS Board of Directors;

    (v) each of the registration statements to be filed by Uniphase to register
        under the Securities Act: (A) on Form S-3, the Uniphase Common Shares to
        be issued from time to time upon exchange of the Exchangeable Shares,
        and (B) on Form S-8, the Uniphase Common Shares to be issued from time
        to time upon the exercise of the Replacement Options; shall have been
        declared effective by the SEC at or prior to the Effective Time and no
        stop order suspending the effectiveness of the registration statements
        shall have been issued, or proceedings for that purpose initiated, by
        the SEC;

    (vi) Exchangeco shall have adopted a shareholder rights plan pursuant to
         which holders of Exchangeable Shares will be granted Exchangeable Share
         Rights to acquire Exchangeable Shares substantially on the same terms

         acquire Uniphase Series B Preferred Shares under the Uniphase Rights
         Agreement; and

   (vii) JDS shall have received confirmation from its outside counsel that the
         tax opinion in this Supplement remains accurate.

TERMINATION AND PAYMENT OF BREAK FEES AND EXPENSES

    The Merger Agreement may be terminated by mutual agreement of JDS and
Uniphase at any time prior to the Effective Date. In addition, if the Effective
Date does not occur on or prior to September 30, 1999, the Merger Agreement
automatically terminates, subject to extension by mutual agreement of the
parties.

                                      S-78

The Merger Agreement automatically terminates upon termination by Furukawa of
its obligations under the Furukawa Support Agreement. See "The
Transaction -- Furukawa Support Agreement".

    Uniphase or JDS may terminate the Merger Agreement prior to the Effective
Date and, in certain circumstances, be paid the Break Fee or U.S.$10 million as
an expense reimbursement, if any condition in the respective party's favour has
not been satisfied at or prior to the Effective Date (subject in some cases to a
30 day cure period), other than as a result of a material default by the
terminating party. In addition, the Merger Agreement may be terminated by: (i)
Uniphase upon the occurrence of any of the JDS Break Fee Events, subject to the
payment by JDS to Uniphase of the Break Fee or (ii) JDS upon the occurrence of
any of the Uniphase Break Fee Events, subject to the payment by Uniphase to JDS
of the Break Fee. Each of JDS or Uniphase may also terminate the Merger
Agreement upon a determination by its respective board of directors that an
Acquisition Proposal is a Superior Proposal, provided that JDS or Uniphase, as
the case may be, is not then in breach or default of any of its obligations
under the Merger Agreement and subject to the payment by JDS or Uniphase, as the
case may be, to the other party of the Break Fee. In the event of termination of
the Merger Agreement based on a determination that a Superior Proposal has been
received by either Uniphase or JDS, 50% of the Break Fee is payable by the
recipient immediately upon termination of the Merger Agreement and the remaining
50% of the Break Fee is payable only (i) if the Superior Proposal is consummated
within nine months of termination of the Merger Agreement or (ii) if a binding
agreement which constitutes the Superior Proposal is entered into within such
nine month period and the Superior Proposal is consummated within 12 months of
termination of the Merger Agreement.

    If either the JDS Shareholders fail to approve the JDS Arrangement
Resolution at the JDS Meeting or, through the fault of JDS, the Arrangement is
not submitted to JDS Shareholders prior to July 31, 1999, in each case in
circumstances in which no Acquisition Proposal shall have been made in respect
of JDS which has not been affirmatively rejected by the JDS Board of Directors,
then Uniphase may terminate the Merger Agreement and JDS shall pay to Uniphase
U.S.$10 million as an expense reimbursement but is not obligated to pay the
Break Fee, unless, within nine months of the termination of the Merger
Agreement, an Acquisition Proposal is consummated in respect of JDS, in which
case the Break Fee, less any amounts previously paid to satisfy the U.S.$10
million expense reimbursement, shall be payable. Similarly, if either the
Uniphase Stockholders fail to approve the Uniphase Transaction Proposal at the
Uniphase Meeting or, through the fault of Uniphase, the Uniphase Transaction
Proposal is not submitted to Uniphase Stockholders prior to July 31, 1999, in
each case in circumstances in which no Acquisition Proposal shall have been made
in respect of Uniphase which has not been affirmatively rejected by the Uniphase
Board of Directors, then JDS may terminate the Merger Agreement and Uniphase
shall pay to JDS U.S.$10 million as an expense reimbursement but is not
obligated to pay the Break Fee, unless, within nine months of the termination of
the Merger Agreement, an Acquisition Proposal is consummated in respect of
Uniphase, in which case the Break Fee, less any amounts previously paid to
satisfy the U.S.$10 million expense reimbursement, shall be payable.

    The Merger Agreement provides that the compensation to be received pursuant
to its terms upon termination is the sole remedy of the parties (other than the
equitable remedies of injunction and specific performance).

                             TRANSACTION MECHANICS

    The following is a summary of the Plan of Arrangement. JDS Shareholders and
Uniphase Stockholders are urged to read the Plan of Arrangement in its entirety.
The Plan of Arrangement is attached as Appendix C to this Supplement.

THE ARRANGEMENT

    Pursuant to the terms of the Plan of Arrangement and the Voting and Exchange
Trust Agreement, commencing at the Effective Time, the following events will
occur:

1.  AMALGAMATION.  JDS, Amalgamation Subco and the Holding Companies, if any,
    shall amalgamate and continue as one company under the CBCA. On the
    Amalgamation:

    (a) each outstanding common share of Amalgamation Subco and each outstanding
       JDS Common Share deemed to be held by Uniphase Nova Scotia as a
       consequence of a JDS Shareholder exercising its Dissent Rights shall be
       converted into one fully paid and non-assessable Amalco Common Share;

                                      S-79

    (b) each outstanding preference share of Amalgamation Subco shall be
       converted into one fully paid and non-assessable Amalco Preference Share;

    (c) each outstanding JDS Common Share that is not held by (i) a Dissenting
       Shareholder who is ultimately entitled to be paid the fair value of its
       JDS Common Shares or (ii) a Holding Company, shall be converted into that
       number of fully paid and non-assessable Class B Non-Voting Preference
       Shares equal to the Exchange Ratio; and

    (d) all Holding Company Shares in respect of a particular Holding Company
       shall be converted into that number of fully paid and non-assessable
       Class B Non-Voting Preference Shares equal to the product of the Exchange
       Ratio and the number of JDS Common Shares held by such Holding Company
       and the JDS Common Shares held by such Holding Company shall be
       cancelled.

    JDS, as the amalgamated company, shall thereafter possess all the property,
    rights, privileges and franchises and shall be subject to all the
    liabilities, contracts and debts of JDS, Amalgamation Subco and the Holding
    Companies, if any.

2.  CAPITAL REORGANIZATION.  Immediately after the Amalgamation, Exchangeco
    shall effect the following capital reorganization:

    (a) each outstanding Class B Non-Voting Preference Share will be transferred
       by the holder thereof, at the JDS Shareholder's election, (i) to
       Exchangeco in exchange for one Exchangeable Share; or (ii) to Uniphase
       Nova Scotia in exchange for one Uniphase Common Share; provided that,
       holders of Class B Non-Voting Preference Shares who are not Canadian
       Residents will not be entitled to elect to receive Exchangeable Shares
       and any election otherwise shall be deemed to be an election to receive
       Uniphase Common Shares and provided that a holder must make the same
       election in respect of all their Class B Non-Voting Preference Shares or
       the election will not be effective;

    (b) each outstanding Class B Non-Voting Preference Share in respect of which
       an election has not been made by the holder thereof, or in respect of
       which an effective election has not been made, will be transferred by the
       holder thereof to Exchangeco in exchange for one Exchangeable Share;
       provided that, each Class B Non-Voting Preference Share in respect of
       which an election has not been made, held by a holder who is not a
       Canadian Resident will be deemed to be transferred by the holder thereof
       to Uniphase Nova Scotia in exchange for one Uniphase Common Share;

    (c) the Class B Non-Voting Preference Shares transferred to Exchangeco will
       be cancelled and each Class B Non-Voting Preference Share transferred to
       Uniphase Nova Scotia will be exchanged for one common share of
       Exchangeco;

    (d) each JDS Option will become a Replacement Option to purchase a number of
       Uniphase Common Shares equal to the product of the Exchange Ratio
       multiplied by the number of JDS Common Shares subject to such JDS Option.
       The Replacement Option will provide for an exercise price per Uniphase
       Common Share equal to the exercise price per share of such JDS Option
       immediately prior to the Effective Time divided by the Exchange Ratio and
       converted into U.S. dollars based on the Noon Buying Rate on the
       Effective Date. Immediately prior to the Effective Time, the JDS Board of
       Directors may resolve to accelerate the vesting schedule for all or a
       portion of the JDS Options such that, immediately following the Effective
       Time, the corresponding Replacement Options (in respect of up to an
       anticipated maximum of 2,000,000 Uniphase Common Shares) will be
       immediately exerciseable; and

    (e) coincident with and as part of the capital reorganization, Uniphase and
       Exchangeco will execute and deliver the Voting and Exchange Trust
       Agreement and Uniphase will issue to and deposit with the Trustee the
       Special Voting Share.

    Uniphase and its affiliates do not currently own any JDS Common Shares and
are prohibited from acquiring any JDS Common Shares prior to the Effective Date
pursuant to the Merger Agreement, except with the prior approval of JDS.

                                      S-80

    Immediately following the Effective Time, JDS' outstanding capital stock
will consist of approximately 79.3 million Amalco Common Shares, all of which
will be held by Exchangeco and Uniphase Nova Scotia and 10,000 Amalco Preference
Shares, all of which will be held by Tory Tory DesLauriers & Binnington,
received in exchange for services rendered. Based on the Exchange Ratio, the
former holders of JDS Common Shares will hold an aggregate of approximately 39.7
million Exchangeable Shares and Uniphase Common Shares. Assuming all JDS Common
Shares are exchanged for Uniphase Common Shares and based upon the number of JDS
Common Shares and Uniphase Common Shares outstanding as of January 27, 1999,
immediately following completion of the Transaction, existing JDS Shareholders
would hold approximately 50% of the outstanding Uniphase Common Shares.

HOLDING COMPANY ALTERNATIVE

    JDS Shareholders who own JDS Common Shares indirectly through a Holding
Company have the option of including such Holding Company in the Amalgamation.
If the Holding Company Alternative is exercised, pursuant to the Amalgamation,
all Holding Company Shares in respect of any particular Holding Company will be
converted into that number of Class B Non-Voting Preference Shares equal to the
product of the Exchange Ratio and the number of JDS Common Shares held by such
Holding Company.

    Pursuant to the Arrangement, JDS Shareholders will receive in exchange for
each Class B Non-Voting Preference Share received either one Exchangeable Share
or one Uniphase Common Share. See "Transaction Mechanics -- The Arrangement".

    JDS Shareholders are advised to review carefully the information under the
heading "Holding Company Alternative" in the JDS Circular for a more detailed
description of the Holding Company Alternative and to consult their own tax
advisors as to the tax consequences to them.

SHARE CERTIFICATES

    At or promptly after the Effective Time, Exchangeco shall deposit with the
Depository, for the benefit of JDS Shareholders who will receive Exchangeable
Shares in connection with the Arrangement, certificates representing the
Exchangeable Shares issued pursuant to the Plan of Arrangement upon exchange of
the Class B Non-Voting Preference Shares into which JDS Common Shares or Holding
Company Shares, if any, were converted on the Amalgamation. Upon surrender to
the Depository of a certificate which, immediately prior to the Effective Time,
represented one or more JDS Common Shares or Holding Company Shares that were
converted into Class B Non-Voting Preference Shares on the Amalgamation and then
exchanged for Exchangeable Shares under the Arrangement, together with other
required documents, a holder of Class B Non-Voting Preference Shares will be
entitled to receive a certificate representing that number of Exchangeable
Shares which such holder has the right to receive.

    At or promptly after the Effective Time, Uniphase Nova Scotia shall deposit
with the Depository, for the benefit of JDS Shareholders who will receive
Uniphase Common Shares in connection with the Arrangement, certificates
representing the Uniphase Common Shares issued pursuant to the Plan of
Arrangement upon exchange of the Class B Non-Voting Preference Shares into which
JDS Common Shares or Holding Company Shares, if any, were converted on the
Amalgamation. Upon surrender to the Depository of a certificate which,
immediately prior to the Effective Time, represented one or more JDS Common
Shares or Holding Company Shares that were converted into Class B Non-Voting
Preference Shares on the Amalgamation and then exchanged for Uniphase Common
Shares under the Arrangement, together with other required documents, a JDS
Shareholder will be entitled to receive a certificate representing that number
of Uniphase Common Shares which such JDS Shareholder has the right to receive.

    No certificates representing Class B Non-Voting Preference Shares will be
issued. Class B Non-Voting Preference Shares will be evidenced by the
certificates representing the JDS Common Shares and Holding Company Shares which
were converted into Class B Non-Voting Preference Shares on the Amalgamation.

    JDS Shareholders are advised to review carefully the information under the
heading "Procedures for Exchange of Share Certificates by Shareholders" in the
JDS Circular for a more detailed description of the

                                      S-81

procedures to be followed by JDS Shareholders in order to obtain certificates
representing the Exchangeable Shares and the Uniphase Common Shares issuable in
the Arrangement.

    JDS Shareholders whose JDS Common Shares are registered in the name of a
broker, investment dealer, bank, trust company or other nominee should contact
that nominee for instructions and assistance in delivering those JDS Common
Shares.

FRACTIONAL SHARES

    If as a result of the Amalgamation, a Person shall become entitled to a
fractional interest in a Class B Non-Voting Preference Share, the fractional
interest in that Class B Non-Voting Preference Share shall be rounded to the
nearest one hundred thousandth of a Class B Non-Voting Preference Share and that
fractional interest, as so rounded, together with any whole Class B Non-Voting
Preference Shares that Person is entitled to receive on the Amalgamation, shall
be evidenced by the certificates representing the JDS Common Shares or Holding
Company Shares held by that Person which were converted into such Class B
Non-Voting Preference Shares on the Amalgamation.

    No fractional Exchangeable Shares or fractional Uniphase Common Shares will
be delivered in exchange for Class B Non-Voting Preference Shares pursuant to
the Arrangement. In lieu of any such fractional securities: (i) each JDS
Shareholder otherwise entitled to a fractional interest in an Exchangeable Share
will receive a cash payment equal to such JDS Shareholder's PRO RATA portion of
the net proceeds after expenses received by the Depository upon the sale of
whole shares representing an accumulation of all fractional interests in
Exchangeable Shares to which all such JDS Shareholders would otherwise be
entitled. The Depository will sell such Exchangeable Shares by private sale
(including by way of sale through the facilities of any stock exchange upon
which the Exchangeable Shares are then listed) as soon as reasonably practicable
following the Effective Date. The aggregate net proceeds after expenses of such
sale will be distributed by the Depository, PRO RATA in relation to the
respective fractions, among the JDS Shareholders otherwise entitled to receive
fractional interests in Exchangeable Shares; and (ii) each JDS Shareholder
otherwise entitled to a fractional interest in a Uniphase Common Share will
receive a cash payment equal to such JDS Shareholder's PRO RATA portion of the
net proceeds after expenses received by the Depository upon the sale of whole
shares representing an accumulation of all fractional interests in Uniphase
Common Shares to which all such JDS Shareholders would otherwise be entitled.
The Depository will sell such Uniphase Common Shares on NASDAQ as soon as
reasonably practicable following the Effective Date. The aggregate net proceeds
after expenses of such sale will be distributed by the Depository, PRO RATA in
relation to the respective fractions, among the JDS Shareholders otherwise
entitled to receive fractional interests in Uniphase Common Shares.

                       DESCRIPTION OF EXCHANGEABLE SHARES

    The following is a summary of the Exchangeable Share Provisions and certain
provisions of the Voting and Exchange Trust Agreement and the Exchangeable Share
Support Agreement, all of which JDS Shareholders and Uniphase Stockholders are
urged to read in their entirety. The Exchangeable Share Provisions, the Voting
and Exchange Trust Agreement and the Exchangeable Share Support Agreement are
attached in or as Appendices C, E and D, respectively, to this Supplement.

GENERAL

    The Exchangeable Shares will be issued by Exchangeco. The Exchangeable
Shares are intended to be economically equivalent to the Uniphase Common Shares.
The Exchangeable Shares will be exchangeable at any time at the option of the
holder on a one-for-one basis, for Uniphase Common Shares. On the Effective
Date, Uniphase, Exchangeco and the Trustee will enter into the Voting and
Exchange Trust Agreement. By furnishing instructions to the Trustee under the
Voting and Exchange Trust Agreement, holders of the Exchangeable Shares will be
able to exercise essentially the same voting rights with respect to Uniphase as
they would have if they had exchanged their Exchangeable Shares for Uniphase
Common Shares. Holders of Exchangeable Shares will also be entitled to receive
from Exchangeco dividends payable in U.S. dollars or Canadian dollars that are
economically equivalent to any cash dividends paid on Uniphase Common Shares.
The Exchangeable Shares are subject to adjustment or modification in the event
of a stock split or other change to

                                      S-82

the capital structure of Uniphase so as to maintain the initial one-to-one
relationship between the Exchangeable Shares and the Uniphase Common Shares.

VOTING, DIVIDEND AND LIQUIDATION RIGHTS

VOTING RIGHTS WITH RESPECT TO EXCHANGECO

    Except as required by law or under the Exchangeable Share Support Agreement,
the terms of the Exchangeable Share Provisions with respect to the amendment
thereof or the Voting and Exchange Trust Agreement, the holders of Exchangeable
Shares are not entitled as such to receive notice of or attend any meeting of
shareholders of Exchangeco or to vote at any such meeting.

VOTING RIGHTS WITH RESPECT TO UNIPHASE

    Pursuant to the Voting and Exchange Trust Agreement, Uniphase will issue the
Special Voting Share to the Trustee for the benefit of the holders (other than
Uniphase and its Affiliates) of the Exchangeable Shares. The Special Voting
Share will have a number of votes, which may be cast at any meeting at which
Uniphase Stockholders are entitled to vote, equal to the number of Exchangeable
Shares outstanding from time to time (other than Exchangeable Shares held by
Uniphase and its Affiliates).

    Each holder of an Exchangeable Share (other than Uniphase and its
Affiliates) on the record date for any meeting at which Uniphase Stockholders
are entitled to vote will be entitled to instruct the Trustee to exercise one of
the votes attached to the Special Voting Share for each Exchangeable Share held
by such holder. The Trustee will exercise each vote attached to the Special
Voting Share only as directed by the relevant holder and, in the absence of
instructions from a holder as to voting, will not exercise such votes. A holder
may, upon instructing the Trustee, obtain a proxy from the Trustee entitling the
holder to vote directly at the relevant meeting the votes attached to the
Special Voting Share to which the holder is entitled. In connection with each
meeting, to the extent that the Trustee has not, upon such instructions, signed
and delivered to holders proxies as aforesaid, the Trustee shall exercise its
voting rights as holder of the Special Voting Share either by proxy or in
person.

    The Trustee will send to the holders of the Exchangeable Shares the notice
of each meeting at which the Uniphase Stockholders are entitled to vote,
together with the related meeting materials and a statement as to the manner in
which the holder may instruct the Trustee to exercise the votes attaching to the
Special Voting Share. Such mailing by the Trustee shall commence on the same day
as Uniphase sends such notice and materials to the Uniphase Stockholders. The
Trustee will also send to the holders of Exchangeable Shares copies of all
information statements, interim and annual financial statements, reports and
other materials sent by Uniphase to the Uniphase Stockholders at the same time
as such materials are sent to the Uniphase Stockholders. To the extent such
materials are provided to the Trustee by Uniphase, the Trustee will also send to
the holders all materials sent by third parties to Uniphase Stockholders,
including dissident proxy circulars and tender and exchange offer circulars, as
soon as reasonably practicable after such materials are delivered to the
Trustee.

    All rights of a holder of Exchangeable Shares to instruct the Trustee to
exercise votes attached to the Special Voting Share will cease upon the exchange
(whether by redemption, retraction or liquidation, or through the exercise of
the Call Rights) of all of such holder's Exchangeable Shares for Uniphase Common
Shares.

    In accordance with the terms of the Exchangeable Share Support Agreement,
Uniphase and its Affiliates will not exercise any voting rights with respect to
any Exchangeable Shares held by it or its Affiliates, although it will appoint
proxyholders with respect to such Exchangeable Shares for the sole purpose of
attending meetings of the holders of Exchangeable Shares in order to be counted
as part of the quorum for such meetings.

DIVIDEND RIGHTS

    Holders of Exchangeable Shares will be entitled to receive, subject to
applicable law and to the next paragraph, dividends (i) in the case of a cash
dividend declared on the Uniphase Common Shares, in an amount in cash for each
Exchangeable Share corresponding to the cash dividend declared on each Uniphase
Common

                                      S-83

Share; (ii) in the case of a stock dividend declared on the Uniphase Common
Shares to be paid in Uniphase Common Shares, in such number of Exchangeable
Shares for each Exchangeable Share as is equal to the number of Uniphase Common
Shares to be paid on each Uniphase Common Share; or (iii) in the case of a
dividend declared on the Uniphase Common Shares in property other than cash or
Uniphase Common Shares, in such type and amount of property as is the same as,
or economically equivalent to, the type and amount of property declared as a
dividend on each Uniphase Common Share. Cash dividends on the Exchangeable
Shares are payable in U.S. dollars or the Canadian Dollar Equivalent thereof, at
the option of Exchangeco. The declaration date, record date and payment date for
dividends on the Exchangeable Shares will be the same as the relevant date for
the corresponding dividends on the Uniphase Common Shares. See "The Companies
after the Transaction -- Dividend Policy".

    In the case of a stock dividend declared on the Uniphase Common Shares to be
paid in Uniphase Common Shares, in lieu of declaring a corresponding stock
dividend on the Exchangeable Shares, the Board of Directors of Exchangeco may,
in its discretion and subject to applicable law, subdivide, redivide or change
(the "subdivision") each issued and unissued Exchangeable Share on the basis
that each Exchangeable Share before the subdivision becomes a number of
Exchangeable Shares as is equal to the sum of (i) a Uniphase Common Share and
(ii) the number of Uniphase Common Shares to be paid as a stock dividend on each
Uniphase Common Share. In such instance, such subdivision shall become effective
on the effective date for the dividend declared on the Uniphase Common Shares
without any further act or formality on the part of the Board of Directors of
Exchangeco or of the holders of Exchangeable Shares. No approval of the holders
of Exchangeable Shares to an amendment to the articles of Exchangeco shall be
required to give effect to such subdivision. The record date for the
determination of the holders of Exchangeable Shares entitled to receive
Exchangeable Shares in connection with any subdivision of Exchangeable Shares
and the effective date of such subdivision shall be the same dates as the record
date and payment date, respectively, for the corresponding stock dividend
declared on Uniphase Common Shares.

LIQUIDATION RIGHTS WITH RESPECT TO EXCHANGECO

    In the event of the liquidation, dissolution or winding-up of Exchangeco or
any other distribution of the assets of Exchangeco among its shareholders for
the purpose of winding-up its affairs, holders of the Exchangeable Shares will
have, subject to applicable law, preferential rights to receive from Exchangeco
the Exchangeco Liquidation Amount for each Exchangeable Share held. Upon the
occurrence of such liquidation, dissolution or winding-up, Uniphase Nova Scotia
will have an overriding Liquidation Call Right to purchase all of the
outstanding Exchangeable Shares (other than Exchangeable Shares held by
affiliates of Uniphase) from the holders thereof on the Exchangeco Liquidation
Date for a purchase price per share equal to the Exchangeco Liquidation Amount.

    Upon the occurrence and during the continuance of an Exchangeco Insolvency
Event, each holder of Exchangeable Shares (other than affiliates of Uniphase)
will be entitled to instruct the Trustee to exercise the Exchange Right with
respect to any or all of the Exchangeable Shares held by such holder, thereby
requiring Uniphase to purchase such Exchangeable Shares from the holder. As soon
as practicable following the occurrence of an Exchangeco Insolvency Event or any
event which may, with the passage of time and/or the giving of notice, become an
Exchangeco Insolvency Event, Exchangeco or Uniphase will give written notice
thereof to the Trustee. As soon as practicable thereafter, the Trustee will then
notify each holder of Exchangeable Shares of such event or potential event and
will advise the holder of its rights with respect to the Exchange Right. The
purchase price payable by Uniphase for each Exchangeable Share purchased under
the Exchange Right will be the Exchangeco Liquidation Amount.

LIQUIDATION RIGHTS WITH RESPECT TO UNIPHASE

    In order for the holders of the Exchangeable Shares to participate on a PRO
RATA basis with the holders of Uniphase Common Shares, on the fifth Business Day
prior to the effective date of a Uniphase Liquidation Event, each Exchangeable
Share (other than those held by affiliates of Uniphase) will, pursuant to the
Automatic Exchange Right, automatically be exchanged for the Exchangeco
Liquidation Amount pursuant to the Voting and Exchange Trust Agreement. Upon a
holder's request and surrender of Exchangeable Share

                                      S-84

certificates, duly endorsed in blank and accompanied by such instruments of
transfer as Uniphase may reasonably require, Uniphase will deliver to such
holder certificates representing an equivalent number of Uniphase Common Shares.
For a description of certain Uniphase obligations with respect to the dividend
and liquidation rights of the holders of Exchangeable Shares, see "Description
of Exchangeable Shares -- Uniphase Support Obligation" below.

RETRACTION

    Subject to the exercise by Uniphase Nova Scotia of its Retraction Call
Right, holders of the Exchangeable Shares will be entitled at any time following
the Effective Time to retract (i.e. require Exchangeco to redeem) any or all of
the Exchangeable Shares held by such holder for a retraction price per share
equal to the Retraction Price. Holders of the Exchangeable Shares may effect
such retraction by presenting (i) a certificate or certificates to Exchangeco or
the Trustee representing the number of Exchangeable Shares the holder desires to
retract; (ii) a duly executed Retraction Request indicating the number of
Exchangeable Shares the holder desires to retract and the Retraction Date and
acknowledging the Retraction Call Right; and (iii) such other documents as may
be required to effect the retraction of the Retracted Shares.

    When a holder requests Exchangeco to redeem Retracted Shares, Uniphase Nova
Scotia will have an overriding Retraction Call Right to purchase on the
Retraction Date all but not less than all of the Retracted Shares, at a purchase
price per share equal to the Retraction Price. Upon receipt of a Retraction
Request, Exchangeco will immediately notify Uniphase Nova Scotia of the
Retraction Request. Uniphase Nova Scotia must then advise Exchangeco within five
Business Days as to whether the Retraction Call Right will be exercised. If
Uniphase Nova Scotia does not so advise Exchangeco, Exchangeco will notify the
holder as soon as possible thereafter that Uniphase Nova Scotia will not
exercise the Retraction Call Right. If Uniphase Nova Scotia advises Exchangeco
that Uniphase Nova Scotia will exercise the Retraction Call Right within such
five Business Day period, then provided the Retraction Request is not revoked by
the holder as described below, the Retraction Request shall thereupon be
considered only to be an offer by the holder to sell the Retracted Shares to
Uniphase Nova Scotia in accordance with the Retraction Call Right.

    A holder may revoke its Retraction Request, in writing, at any time prior to
the close of business on the Business Day preceding the Retraction Date, in
which case the Retracted Shares will neither be purchased by Uniphase Nova
Scotia nor be redeemed by Exchangeco. If a holder does not revoke its Retraction
Request, on the Retraction Date, the Retracted Shares will be purchased by
Uniphase Nova Scotia or redeemed by Exchangeco, as the case may be, in each case
as set out above.

    If, as a result of solvency requirements or applicable law, Exchangeco is
not permitted to redeem all Retracted Shares tendered by a retracting holder,
Exchangeco will redeem only those Retracted Shares tendered by the holder
(rounded down to a whole number of shares) as would not be contrary to such
provisions of applicable law. The Trustee, on behalf of the holder of any
Retracted Shares not so redeemed by Exchangeco, will require Uniphase to
purchase the Retracted Shares not redeemed on the Retraction Date, pursuant to
the Exchange Right.

REDEMPTION

    Subject to applicable law and the Redemption Call Right, on the Redemption
Date, Exchangeco will redeem all but not less than all of the then outstanding
Exchangeable Shares for a redemption price per share equal to the Redemption
Price. Exchangeco will, at least 60 days prior to the Redemption Date, or such
number of days as the board of directors of Exchangeco may determine to be
reasonably practicable under the circumstances in respect of a Redemption Date
arising in connection with, among other events, a Uniphase Control Transaction,
an Exchangeable Share Voting Event or an Exempt Exchangeable Share Voting Event,
provide the registered holders of the Exchangeable Shares with written notice of
the proposed redemption of the Exchangeable Shares by Exchangeco or the purchase
of the Exchangeable Shares by Uniphase Nova Scotia pursuant to the Redemption
Call Right described below.

    Uniphase Nova Scotia will have an overriding Redemption Call Right to
purchase on the Redemption Date all but not less than all of the Exchangeable
Shares then outstanding (other than Exchangeable Shares held by

                                      S-85

affiliates of Uniphase) for a purchase price per share equal to the Redemption
Price. Upon the exercise of the Redemption Call Right, holders will be obligated
to sell their Exchangeable Shares to Uniphase Nova Scotia. If Uniphase Nova
Scotia exercises the Redemption Call Right, Exchangeco's right and obligation to
redeem the Exchangeable Shares on such Redemption Date will terminate.

EARLY REDEMPTION

    In certain circumstances, Exchangeco has the right to require a redemption
of the Exchangeable Shares prior to March 31, 2014. Subject to the terms and
conditions of the Furukawa Support Agreement (which provides Furukawa with
certain consent rights) and the Redemption Call Right, an early redemption may
occur upon:

    (i) there being fewer than 992,372 Exchangeable Shares outstanding (other
        than Exchangeable Shares held by Uniphase and its Affiliates), provided
        that such number may be adjusted by the board of directors of Exchangeco
        in certain circumstances described in the Exchangeable Share Provisions;

    (ii) the occurrence of a Uniphase Control Transaction, provided that the
         board of directors of Exchangeco determines (A) that it is not
         reasonably practicable to substantially replicate the terms and
         conditions of the Exchangeable Shares in connection with the Uniphase
         Control Transaction and (B) that the redemption of the Exchangeable
         Shares is necessary to enable the completion of the Uniphase Control
         Transaction;

   (iii) a proposal being made for an Exchangeable Share Voting Event, provided
         that the board of directors of Exchangeco determines that it is not
         reasonably practicable to accomplish the business purpose intended by
         the Exchangeable Share Voting Event (which business purpose must be
         BONA FIDE and not for the primary purpose of causing the occurrence of
         a Redemption Date) in any other commercially reasonable manner that
         does not result in an Exchangeable Share Voting Event; or

    (iv) the failure by the holders of the Exchangeable Shares to approve or
         disapprove, as applicable, an Exempt Exchangeable Share Voting Event.

RANKING

    The Exchangeable Shares will be entitled to a preference over the common
shares of Exchangeco and any other shares ranking junior to the Exchangeable
Shares with respect to the payment of dividends and the distribution of assets
in the event of a liquidation, dissolution or winding-up of Exchangeco, whether
voluntary or involuntary, or any other distribution of the assets of Exchangeco,
among its shareholders for the purpose of winding-up its affairs.

CERTAIN RESTRICTIONS

    Without the approval of the holders of the Exchangeable Shares as set forth
below under "Description of Exchangeable Shares -- Amendment and Approval",
Exchangeco will not:

    (a) pay any dividends on the common shares of Exchangeco, or any other
       shares ranking junior to the Exchangeable Shares, other than stock
       dividends payable in common shares of Exchangeco, or any such other
       shares ranking junior to the Exchangeable Shares, as the case may be;

    (b) redeem, purchase or make any capital distribution in respect of common
       shares of Exchangeco, or any other shares ranking junior to the
       Exchangeable Shares;

    (c) redeem or purchase any other shares of Exchangeco ranking equally with
       the Exchangeable Shares with respect to the payment of dividends or on
       any liquidation distribution;

    (d) issue any Exchangeable Shares other than (i) pursuant to any shareholder
       rights plan adopted by Exchangeco; (ii) by way of stock dividend to the
       holders of Exchangeable Shares, or (iii) by way of any subdivision
       described above under the heading "Description of Exchangeable
       Shares -- Dividend Rights"; or

                                      S-86

    (e) issue any shares of Exchangeco ranking equally with, or superior to, the
       Exchangeable Shares other than by way of stock dividends to the holders
       of such Exchangeable Shares.

    The restrictions in clauses (a), (b), (c) and (d) above will not apply at
any time when the dividends on the outstanding Exchangeable Shares corresponding
to dividends declared and paid on the Uniphase Common Shares have been declared
and paid in full.

AMENDMENT AND APPROVAL

    The rights, privileges, restrictions and conditions attaching to the
Exchangeable Shares may be added to, changed or removed only with the approval
of the holders thereof. Any such approval or any other approval or consent to be
given by the holders of the Exchangeable Shares will be deemed to have been
sufficiently given if given in accordance with applicable law subject to a
minimum requirement that such approval or consent be evidenced by a resolution
passed by not less than two-thirds of the votes cast on such resolution at a
meeting of the holders of Exchangeable Shares duly called and held at which
holders of at least 35% of the then outstanding Exchangeable Shares are present
or represented by proxy. In the event that no such quorum is present at such
meeting within one-half hour after the time appointed therefor, then the meeting
will be adjourned to such place and time (not less than five days later) as may
be designated by the Chairman of such meeting. At such adjourned meeting, the
holders of Exchangeable Shares present or represented by proxy may transact the
business for which the meeting was originally called and a resolution passed
thereat by the affirmative vote of not less than two-thirds of the votes cast on
such resolution will constitute the approval or consent of the holders of the
Exchangeable Shares.

EXCHANGEABLE SHARE RIGHTS

    Prior to the Effective Time, Exchangeco will adopt an Exchangeable Share
rights plan substantially equivalent to the Uniphase Rights Agreement. Pursuant
thereto, each Exchangeable Share issued in the Arrangement will have an
associated Exchangeable Share Right entitling the holder of such Exchangeable
Share Right to acquire additional Exchangeable Shares on terms and conditions
substantially the same as the terms and conditions upon which a holder of the
Uniphase Common Shares is entitled to acquire either a Uniphase Unit or, in
certain circumstances, Uniphase Common Shares (with the definitions of
beneficial ownership, the calculation of percentage ownership and the number of
shares outstanding and related provisions applying, as appropriate, to Uniphase
Common Shares and Exchangeable Shares as though they were the same security).
The Exchangeable Share Rights are intended to have characteristics essentially
equivalent in economic effect to the Uniphase Rights. See "Uniphase Capital
Stock -- Uniphase Rights Agreement".

UNIPHASE SUPPORT OBLIGATION

    Pursuant to the Exchangeable Share Support Agreement, Uniphase will make the
following covenants for so long as any Exchangeable Shares (other than
Exchangeable Shares owned by Uniphase or its Affiliates) remain outstanding:

    (i) Uniphase will not declare or pay dividends on the Uniphase Common Shares
        unless Exchangeco is able to (x) declare and pay and simultaneously
        declares or pays, as the case may be, an equivalent dividend on the
        Exchangeable Shares or (y) subdivide and simultaneously subdivides the
        Exchangeable Shares in lieu of stock dividend (as provided for in the
        Exchangeable Share Provisions);

    (ii) Uniphase will advise Exchangeco in advance of the declaration of any
         dividend on the Uniphase Common Shares and ensure that (x) the
         declaration date, record date and payment date for dividends on the
         Exchangeable Shares are the same as those for the corresponding
         dividend on the Uniphase Common Shares or (y) the record date and
         effective date for a subdivision of the Exchangeable Shares in lieu of
         stock dividend (as provided for in the Exchangeable Share Provisions)
         are the same as the record date and payment date for the corresponding
         stock dividend on the Uniphase Common Shares;

   (iii) Uniphase will ensure that the record date for any dividend declared on
         the Uniphase Common Shares is not less than 10 Business Days after the
         declaration date of such dividend;

                                      S-87

    (iv) Uniphase will take all actions and do all things reasonably necessary
         or desirable to enable and permit Exchangeco, in accordance with
         applicable law, to pay to the holders of the Exchangeable Shares the
         applicable Exchangeco Liquidation Amount, Redemption Price and
         Retraction Price in the event of a liquidation, dissolution or
         winding-up of Exchangeco, a Retraction Request by a holder of
         Exchangeable Shares or a redemption of Exchangeable Shares by
         Exchangeco;

    (v) Uniphase will take all actions and do all things reasonably necessary or
        desirable to enable and permit Uniphase Nova Scotia, in accordance with
        applicable law, to perform its obligations arising upon the exercise by
        it of the Call Rights, including the delivery of Uniphase Common Shares
        in accordance with the provisions of the applicable Call Right; and

    (vi) if Uniphase becomes a "specified financial institution" (as such term
         is defined in the Canadian Tax Act) or does not deal at arms' length
         with such a person, Uniphase will take all such actions and do all such
         things as are reasonably necessary or desirable to cause Uniphase Nova
         Scotia to exercise the Retraction Call Right if requested to do so by a
         holder of Exchangeable Shares making a Retraction Request.

    The Exchangeable Share Support Agreement and the Exchangeable Share
Provisions provide that, without the prior approval of Exchangeco and the
holders of the Exchangeable Shares given in the manner set forth above under
"Description of Exchangeable Shares -- Amendment and Approval", Uniphase will
not issue or distribute additional Uniphase Common Shares, securities
exchangeable for or convertible into or carrying rights to acquire Uniphase
Common Shares, rights, options or warrants to subscribe therefor, evidences of
indebtedness or other assets, to all or substantially all holders of Uniphase
Common Shares, nor shall Uniphase change the Uniphase Common Shares, unless the
same or an economically equivalent distribution on or change to the Exchangeable
Shares (or in the rights of the holders thereof) is made simultaneously. The
Exchangeco board of directors is conclusively empowered to determine in good
faith and in its sole discretion whether any corresponding distribution on or
change to the Exchangeable Shares is the same as or economically equivalent to
any proposed distribution on or change to the Uniphase Common Shares. IN THE
EVENT OF ANY PROPOSED TENDER OFFER, SHARE EXCHANGE OFFER, ISSUER BID, TAKE-OVER
BID OR SIMILAR TRANSACTION WITH RESPECT TO THE UNIPHASE COMMON SHARES WHICH IS
RECOMMENDED BY THE UNIPHASE BOARD OF DIRECTORS AND IN CONNECTION WITH WHICH THE
EXCHANGEABLE SHARES ARE NOT REDEEMED BY EXCHANGECO OR PURCHASED BY UNIPHASE NOVA
SCOTIA PURSUANT TO THE REDEMPTION CALL RIGHT, UNIPHASE WILL USE REASONABLE
EFFORTS TO TAKE ALL ACTIONS NECESSARY OR DESIRABLE TO ENABLE HOLDERS OF
EXCHANGEABLE SHARES TO PARTICIPATE IN SUCH TRANSACTION TO THE SAME EXTENT AND ON
AN ECONOMICALLY EQUIVALENT BASIS AS THE HOLDERS OF UNIPHASE COMMON SHARES.

    In order to assist Uniphase to comply with its obligations under the
Exchangeable Share Support Agreement and to permit Uniphase Nova Scotia to
exercise the Call Rights, Exchangeco is required to notify Uniphase and Uniphase
Nova Scotia of the occurrence of certain events, such as the liquidation,
dissolution or winding-up of Exchangeco, and Exchangeco's receipt of a
Retraction Request from a holder of Exchangeable Shares.

    Under the Exchangeable Share Support Agreement, Uniphase has agreed not to
exercise any voting rights attached to the Exchangeable Shares owned by it or
any of its Affiliates on any matter considered at meetings of holders of
Exchangeable Shares. Uniphase has also agreed to use its reasonable efforts to
enable Exchangeco to maintain a listing for the Exchangeable Shares on a
Canadian stock exchange.

    With the exception of administrative changes for the purpose of adding
covenants of any or all parties, making certain necessary amendments or curing
ambiguities or clerical errors (in each case provided that the board of
directors of each of Uniphase, Exchangeco and Uniphase Nova Scotia are of the
opinion that such amendments are not prejudicial to the interests of the holders
of the Exchangeable Shares), the Exchangeable Share Support Agreement may not be
amended without the approval of the holders of the Exchangeable Shares given in
the manner set forth above under "Description of Exchangeable
Shares -- Amendment and Approval".

                      THE COMPANIES AFTER THE TRANSACTION

GENERAL

    Upon completion of the Arrangement and the approval of the Uniphase
Additional Proposals, Uniphase will be renamed JDS Uniphase Corporation and will
continue to be a corporation governed by the DGCL. Uniphase will continue to
have its registered office located at 163 Baypointe Parkway, San Jose,
California, U.S.A., 95134 (Tel. No. (408) 434-1800). After the Effective Time,
Uniphase will indirectly own all of the voting securities of JDS, which will be
renamed JDS Uniphase Inc. and will continue to be a corporation governed by the
CBCA. The registered office of JDS will continue to be located at 570 West Hunt
Club Road, Nepean, Ontario, Canada, K2G 5W8 (Tel. No. (613) 727-1304). The
executive offices of JDS Uniphase will be located in both San Jose and Nepean.
The registered office of Exchangeco will be located at 570 West Hunt Club Road,
Nepean, Ontario, Canada, K2G 5W8 (Tel. No. (613) 727-1304).

PLANS AND PROPOSALS

    Uniphase and JDS believe that the Transaction represents an excellent
opportunity to create a global advanced fiberoptic component and module
manufacturing company that will enjoy benefits of increased size, a more
diversified asset base, low production costs and enhanced positioning to take
advantage of opportunities for growth. Uniphase and JDS also believe that the
combined company will benefit from the complementary skills and expertise of
their respective management teams. See "The Transaction -- Reasons for the
Transaction".

    Uniphase and JDS intend to preserve their existing businesses and core
competencies, operating through JDS Uniphase, in all material business segments
in which Uniphase and JDS currently operate. JDS Uniphase will maintain a
significant presence in both San Jose, California and Nepean, Ontario. Uniphase
and JDS do not anticipate reductions in the workforces of the two companies as a
result of the Transaction.

    Following the closing of the Transaction, JDS Uniphase will continue to
operate the businesses currently conducted by each of JDS and Uniphase at their
existing facilities. Current manufacturing locations will not be changed but
will be evaluated by JDS Uniphase on a long-term basis following the Effective
Date to determine the most advantageous sites for the combined entity for its
manufacturing activities, particularly for new product offerings. The sales and
marketing organizations of the two companies will be integrated following the
Effective Date, as will their respective administrative functions. It is
anticipated that JDS Uniphase will integrate the different computer information
systems of Uniphase and JDS. Particular emphasis in this integration effort will
be on the integration of the administrative, finance and sales functions of the
two information systems.

    Direction for research and development activities of JDS Uniphase will be
centralized within management of the combined entity. Research and development
will focus both on continued development of each of JDS' and Uniphase's existing
products and more integrated module products that combine the products of both
companies.

(1) Beneficial ownership is determined in accordance with the rules of the SEC.
    In computing the number of shares beneficially owned by a person and the
    percentage ownership of that person, Uniphase Common Shares or JDS Common
    Shares subject to options held by that

                                      S-91

    person that are currently exercisable or exercisable within 60 days of May
    14, 1999 are deemed outstanding. Such shares, however, are not deemed
    outstanding for the purposes of computing the percentage ownership of each
    other person. To Uniphase's and JDS' knowledge, except as set forth in the
    footnotes to this table and subject to applicable community property laws,
    each person named in the table has sole voting and investment power with
    respect to the shares set forth opposite such person's name.

(2) Percentage of ownership is based on 40,464,807 Uniphase Common Shares
    outstanding on May 14, 1999 and 78,411,178 JDS Common Shares outstanding on
    May 14, 1999 multiplied by the Exchange Ratio.

(5) Includes 93,250 shares subject to stock options currently exercisable or
    exercisable within 60 days of May 14, 1999 and 4,760 shares held by Mr.
    Muller's daughter.

(6) Includes 25,731 shares subject to stock options currently exercisable or

PRINCIPAL HOLDERS OF SECURITIES

    At the time the Merger Agreement was executed, Furukawa owned 40,489,670 JDS
Common Shares. On February 16, 1999, Furukawa sold 3,130,000 of such JDS Common
Shares at a price of Cdn.$60 per share. The sale was made on a private placement
basis to various purchasers pursuant to an underwriting agreement among
Furukawa, JDS and CIBC World Markets dated February 3, 1999.

                                      S-93

    Based on Furukawa's ownership of 37,359,670 JDS Common Shares (and no
Uniphase Common Shares) as of the date of this Supplement, after giving effect
to the Arrangement, a subsidiary of Furukawa will be the beneficial owner of
18,999,260 Exchangeable Shares, which will represent approximately 24% of the
aggregate outstanding Uniphase Common Shares and Exchangeable Shares taken
together following consummation of the Arrangement. See "The
Transaction -- Furukawa Support Agreement" for a summary of the rights of a
subsidiary or subsidiaries of Furukawa (or its or their permitted transferees)
to require Uniphase to register the Uniphase Common Shares held by the
subsidiary or subsidiaries (or its or their permitted transferees) under the
Securities Act or to require Exchangeco to qualify a prospectus under Canadian
securities laws in respect of the Exchangeable Shares held by the subsidiary or
subsidiaries (or its or their permitted transferees) pursuant to the Furukawa
Registration Rights Agreement. To the knowledge of Uniphase, JDS and their
respective directors and officers, other than Furukawa and American Express
Company, there are no persons who, had the Arrangement occurred on May 14, 1999,
would beneficially own, directly or indirectly, or exercise control or direction
over, in excess of 5% of the outstanding Uniphase Common Shares. However, since
beneficial ownership of less than 10% of the JDS Common Shares is not required
to be disclosed under Canadian securities laws, it is difficult to identify
beneficial holders of less than 10% of the issued and outstanding JDS Common
Shares.

    See "Business of JDS -- Security Ownership" and "Business of
Uniphase -- Security Ownership" for information with respect to securities of
JDS and Uniphase currently owned by certain directors, officers and principal
shareholders of JDS and Uniphase, respectively. In addition, see "The Companies
after the Transaction -- Directors and Officers" for pro forma information with
respect to ownership of securities of JDS Uniphase by the initial directors and
senior officers of JDS Uniphase.

DIVIDEND POLICY

    It is anticipated that JDS Uniphase will retain future earnings to finance
the development of its business and, accordingly, will not pay dividends on its
outstanding shares in the foreseeable future. Determinations to pay future
dividends and the amount thereof will be made by the board of directors of JDS
Uniphase and will depend on its future earnings, capital requirements, financial
condition and other relevant factors.

INDEPENDENT AUDITORS

    Ernst & Young LLP, the current auditors of Uniphase, will be the independent
auditors of JDS Uniphase and its subsidiaries, including Exchangeco.

TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for the Uniphase Common Shares in the
United States is and after the Effective Date will be American Stock Transfer &
Trust Company, New York, New York. Following the Effective Date, the transfer
agent and registrar for the Exchangeable Shares in Canada will be CIBC Mellon
Trust Company, Toronto, Ontario.

                             UNIPHASE CAPITAL STOCK

    The following summary of certain provisions of Uniphase capital stock
describes all material provisions of the Uniphase capital stock, but does not
purport to be complete and is subject to, and qualified in its entirety by, the
Uniphase Charter and Uniphase Bylaws and the provisions of applicable law.

    The authorized capital stock of Uniphase consists of 100,000,000 Uniphase
Common Shares, U.S.$.001 par value per share, and 1,000,000 Uniphase Preferred
Shares, U.S.$0.001 par value per share, 100,000 of which are designated Uniphase
Series A Preferred Shares and 100,000 of which are designated Uniphase Series B
Preferred Shares. As of the Uniphase Record Date, there were 40,480,490 Uniphase
Common Shares issued and outstanding, 100,000 Uniphase Series A Preferred Shares
issued and outstanding, and no Uniphase Series B Preferred Shares issued and
outstanding. The Uniphase Stockholders are being asked to consider and approve a
proposal to increase the number of authorized Uniphase Common Shares to
200,000,000 shares. Uniphase Stockholders should review the Uniphase Proxy
Statement for details of this proposal. In addition, pursuant to the Plan of
Arrangement, the Special Voting Share will be issued to the Trustee. See
"Uniphase Capital Stock --

                                      S-94

Special Voting Share". The authorized capital stock of Uniphase will be
otherwise unchanged and will be the authorized capital stock of JDS Uniphase.

COMMON SHARES

    The holders of Uniphase Common Shares are entitled to one vote for each
share held of record on all matters submitted to a vote of the stockholders.
Holders of Uniphase Common Shares do not have cumulative voting rights in the
election of directors. Subject to preferences that may be granted to any then
outstanding Uniphase Preferred Shares, holders of Uniphase Common Shares are
entitled to receive ratably such dividends as may be declared by the Uniphase
Board of Directors out of funds legally available therefor as well as any
distributions to the stockholders. In the event of a liquidation, dissolution or
winding up of Uniphase, holders of Uniphase Common Shares are entitled to share
ratably in all assets of Uniphase remaining after payment of liabilities and the
liquidation preference of any then outstanding Uniphase Preferred Shares.
Holders of Uniphase Common Shares have no preemptive or other subscription or
conversion rights. There are no redemption or sinking fund provisions applicable
to the Uniphase Common Shares. All outstanding Uniphase Common Shares are, and
all Uniphase Common Shares to be outstanding upon completion of the Transaction
and upon exchange of Exchangeable Shares or exercise of options for Uniphase
Common Shares will be, validly issued, fully paid and nonassessable.

PREFERRED SHARES

    The Uniphase Board of Directors has the authority, without further action by
the Uniphase Stockholders, to issue up to 800,000 Uniphase Preferred Shares in
one or more series and to fix the rights, preferences, privileges and
restrictions thereof, including dividend rights, conversion rights, voting
rights, terms of redemption, liquidation preferences, sinking fund terms and the
number of shares constituting any series or the designation of such series. The
issuance of Uniphase Preferred Shares could adversely affect the voting power of
holders of Uniphase Common Shares and the likelihood that such holders will
receive dividend payments and payments upon liquidation and could have the
effect of delaying, deterring or preventing a change in control of Uniphase.

SERIES A PREFERRED SHARES

    Uniphase currently has 100,000 Uniphase Series A Preferred Shares
authorized, issued and outstanding, all of which were issued to Philips in
connection with the acquisition of Uniphase Netherlands B.V. ("UNL"). The
Uniphase Series A Preferred Shares are convertible into Uniphase Common Shares
upon the occurrence of certain events described in the Series A Preferred
Conversion and Redemption Agreement dated as of June 9, 1998, by and between
Uniphase and Philips. The Uniphase Common Shares into which the Uniphase Series
A Preferred Shares are convertible are calculated based upon (i) unit shipments
of certain products by UNL through June 30, 2002, and (ii) the trading price of
Uniphase Common Shares at the time such calculation is determined.

    The Uniphase Series A Preferred Shares rank junior to any other class of
preferred stock that hereafter may be issued by Uniphase as to the payment of
dividends and the distribution of assets upon liquidation, unless the terms of
any such series or class provide otherwise. The Uniphase Series A Preferred
Shares have no voting rights except as required by law and except that approval
of Philips (as long as Philips is a holder of Uniphase Series A Preferred
Shares) or more than 50% of the outstanding Uniphase Series A Preferred Shares
(in the event that Philips is no longer a holder of Uniphase Series A Preferred
Shares) is required to alter the Uniphase Charter so as to (i) adversely affect
the rights and privileges of the holders of the Uniphase Series A Preferred
Shares, or (ii) increase the number of authorized Uniphase Series A Preferred
Shares. The Uniphase Series A Preferred Shares have no right to dividends or
other distributions. A majority of the holders of the Uniphase Series A
Preferred Shares have the right to cause Uniphase to redeem the outstanding
Uniphase Series A Preferred Shares or convert such shares into Uniphase Common
Shares if certain events occur on or before June 30, 2002. In addition, each
Uniphase Series A Preferred Share that has not been redeemed or converted prior
to July 1, 2002, will automatically be converted into Uniphase Common Shares.

                                      S-95

SERIES B PREFERRED SHARES

    Uniphase currently has 100,000 Uniphase Series B Preferred Shares
authorized, of which none are issued and outstanding. Uniphase Series B
Preferred Shares are nonredeemable and subordinate to any other series of
Uniphase Preferred Shares or other preferred stock that may be issued by
Uniphase.

    Uniphase Series B Preferred Shares will be issued in Uniphase Units. Each
Uniphase Unit will have a minimum preferential quarterly dividend of U.S.$0.01
or any higher per share dividend declared on Uniphase Common Shares. In the
event of liquidation, the holder of a Uniphase Unit will receive a preferred
liquidation payment equal to the greater of U.S.$0.01 per Uniphase Unit and the
per share amount paid in respect of a Uniphase Common Share.

    Each Uniphase Unit will have one vote on all matters submitted to a vote of
the Uniphase Stockholders, voting together with the Uniphase Common Shares. In
the event of any merger, consolidation or other transaction in which Uniphase
Common Shares are exchanged, each Uniphase Unit will be entitled to receive the
per share amount paid in respect of each Uniphase Common Share. The rights of
holders of the Uniphase Series B Preferred Shares with respect to dividends,
liquidation and voting, and in the event of mergers and consolidations, are
protected by antidilution provisions customary in the United States.

    Uniphase Units are issuable upon exercise of the Uniphase Rights in
accordance with the Uniphase Rights Agreement. Because of the nature of the
dividend, liquidation and voting rights of the Uniphase Series B Preferred
Shares, the economic value of one Uniphase Unit that may be acquired upon the
exercise of each Uniphase Right should approximate the economic value of one
Uniphase Common Share. See "Uniphase Capital Stock -- Uniphase Rights
Agreement".

UNIPHASE RIGHTS AGREEMENT

    On June 11, 1998, the Uniphase Board of Directors authorized and declared a
dividend distribution of one Uniphase Right for each outstanding Uniphase Common
Share, to stockholders of record at the close of business on July 6, 1998, and
authorized the issuance of one Uniphase Right with each Uniphase Common Share
issued (including shares distributed from treasury) by Uniphase between July 6,
1998 and the Distribution Date. Each Uniphase Right entitles the registered
holder, subject to the terms of the Uniphase Rights Agreement, to purchase from
Uniphase a Uniphase Unit at a purchase price of U.S.$270 per Uniphase Unit,
subject to adjustment.

    The Uniphase Rights are attached to all certificates representing
outstanding Uniphase Common Shares, and no separate Uniphase Rights certificates
have been distributed. The Uniphase Rights will separate from Uniphase Common
Shares, and the Distribution Date will occur upon the earlier of (i) ten days
following a public announcement (the date of such announcement being the "Stock
Acquisition Date") that a person or group of affiliated or associated persons
(as such terms are defined in Rule 12b-2 of the General Rules and Regulations
under the Securities Act) has acquired or otherwise obtained beneficial
ownership (as defined in the Uniphase Rights Agreement) of 15% or more of the
then outstanding Uniphase Common Shares (an "Acquiring Person"), or (ii) ten
business days (or such later date as may be determined by action of the Uniphase
Board of Directors prior to such time as any person becomes an Acquiring Person)
following the commencement of a tender offer or exchange offer that would result
in a person or group beneficially owning 15% or more of the then outstanding
Uniphase Common Shares. Until the Distribution Date, (i) the Uniphase Rights
will be evidenced by Uniphase Common Share certificates and will be transferred
with and only with such Uniphase Common Shares certificates, (ii) new Uniphase
Common Share certificates issued after July 6, 1998 (also including shares
distributed from treasury) will contain a notation incorporating the Uniphase
Rights Agreement by reference and (iii) the surrender for transfer of any
certificates representing outstanding Uniphase Common Shares will also
constitute the transfer of the Uniphase Rights associated with Uniphase Common
Shares represented by such certificates.

    The Uniphase Rights are not exercisable until the Distribution Date and will
expire at the close of business on the tenth anniversary of the Uniphase Rights
Agreement unless earlier redeemed or exchanged by Uniphase as described below.
Under certain circumstances the exercisability of the Uniphase Rights may be
suspended. In

                                      S-96

no event, however, will the Uniphase Rights be exercisable prior to the
expiration of the period in which they may be redeemed.

    As soon as practicable after the Distribution Date, Uniphase Rights
Certificates will be mailed to holders of record of Uniphase Common Shares as of
the close of business on the Distribution Date and, thereafter, the separate
Uniphase Rights Certificates alone will represent the Uniphase Rights.

    If a person becomes an Acquiring Person, then each holder of a Uniphase
Right will thereafter have the right to receive, upon exercise, Uniphase Units
or, at the option of the Uniphase Board of Directors, Uniphase Common Shares
(or, in certain circumstances, cash, property or other securities of Uniphase)
having a value equal to two times the exercise price of the Uniphase Right. The
exercise price is the purchase price multiplied by the number of Uniphase Units
issuable upon exercise of a Uniphase Right prior to the event described in this
paragraph. Notwithstanding any of the foregoing, following the occurrence of the
event set forth in this paragraph, all Rights that are, or (under certain
circumstances specified in the Uniphase Rights Agreement) were, beneficially
owned by any Acquiring Person will be null and void.

    In the event that, at any time following the date that any person becomes an
Acquiring Person, (i) Uniphase is acquired in a merger or other business
combination transaction and Uniphase is not the surviving corporation, (ii) any
person merges with Uniphase and all or part of the Uniphase Common Shares is
converted or exchanged for securities, cash or property of Uniphase or any other
person or (iii) 50% or more of Uniphase's assets or earning power is sold or
transferred, each holder of a Uniphase Right (except Uniphase Rights which
previously have been voided as described above) shall thereafter have the right
to receive, upon exercise, common shares of the Acquiring Person having a value
equal to two times the exercise price of the Uniphase Right.

    The purchase price payable, and the number of Uniphase Units issuable, upon
exercise of the Uniphase Rights are subject to adjustment from time to time to
prevent dilution (i) in the event of a stock dividend on, or a subdivision,
combination or reclassification of, the Uniphase Series B Preferred Shares, (ii)
if holders of the Uniphase Series B Preferred Shares are granted certain rights
or warrants to subscribe for Uniphase Series B Preferred Shares or convertible
securities at less than the current market price of the Uniphase Series B
Preferred Shares, or (iii) upon the distribution to the holders of the Uniphase
Series B Preferred Shares of evidences of indebtedness, cash or assets
(excluding regular quarterly cash dividends) or of subscription rights or
warrants (other than those referred to above).

    With certain exceptions, no adjustment in the purchase price will be
required until cumulative adjustments amount to at least 1% of the purchase
price. Uniphase is not required to issue fractional Uniphase Series B Preferred
Shares (other than fractions which are integral multiples of a Uniphase Unit
which may be evidenced by depositary receipts). In lieu thereof, an adjustment
in cash may be made based on the current market price of a Uniphase Series B
Preferred Share on the day of exercise.

    At any time until ten days following the Stock Acquisition Date, a majority
of the Uniphase Board of Directors may redeem the Uniphase Rights in whole, but
not in part, at a price of U.S.$.01 per Uniphase Right (subject to adjustment in
certain events) (the "Uniphase Rights Redemption Price") payable, at the
election of the majority of the Uniphase Board of Directors, in cash or Uniphase
Common Shares. Immediately upon the action of a majority of the Uniphase Board
of Directors (including, following the date on which there is an Acquiring
Person, a majority of the Independent Directors) ordering the redemption of the
Uniphase Rights, the Uniphase Rights will terminate and the only right of the
holders of Uniphase Rights will be to receive the Uniphase Rights Redemption
Price.

    Uniphase may at any time after there is an Acquiring Person, by action of a
majority of the Uniphase Board of Directors, exchange all or part of the then
outstanding and exercisable Uniphase Rights (other than Uniphase Rights that
shall have become null and void) for Uniphase Common Shares pursuant to a
one-for-one exchange ratio, as adjusted. Until a Uniphase Right is exercised,
the holder thereof, as such, will have no rights as a stockholder of Uniphase,
including, without limitation, the right to vote or to receive dividends. While
the distribution of the Uniphase Rights will not be taxable to stockholders or
to Uniphase, stockholders may, depending upon the circumstances, recognize
taxable income in the event that the Uniphase Rights become exercisable for
Uniphase Units (or other consideration).

                                      S-97

    Any of the provisions of the Uniphase Rights Agreement may be amended
without the approval of the holders of Uniphase Common Shares at any time prior
to the Distribution Date. After the Distribution Date, the provisions of the
Uniphase Rights Agreement may be amended in order to cure any ambiguity, defect
or inconsistency, to make changes which do not adversely affect the interests of
holders of Uniphase Rights (excluding the interests of any Acquiring Person), or
to shorten or lengthen any time period under the Uniphase Rights Agreement;
provided, however, that no amendment may be made to adjust (i) the time period
governing redemption at such time as the Uniphase Rights are not redeemable or
(ii) any other time period unless such lengthening is for the purpose of
protecting, enhancing or clarifying the Uniphase Rights of and/or benefiting,
the holders of Uniphase Rights. In addition, after a person becomes an Acquiring
Person, no amendment or supplement may be made without the approval of a
majority of the Uniphase Board of Directors.

    Upon completion of the Transaction, for purposes of the Uniphase Rights
Agreement, beneficial ownership of Exchangeable Shares will be treated as
beneficial ownership of Uniphase Common Shares and calculations of percentage
ownership, the number of shares outstanding and related provisions will be made
on a basis that treats the Uniphase Common Shares and the Exchangeable Shares as
though they were the same security. In addition, pursuant to the Furukawa
Support Agreement, on or prior to the Effective Date, the Uniphase Rights
Agreement will be amended to provide that (i) Furukawa and its Affiliates will
not be "Acquiring Persons" as a result of Furukawa's direct or indirect
acquisition of Exchangeable Shares or Uniphase Common Shares pursuant to the
Merger Agreement, (ii) so long as Furukawa and its Affiliates taken as a whole
own collectively at least 5% of the issued and outstanding Exchangeable Shares
and Uniphase Common Shares, taken together, the definition of "Acquiring Person"
will not be amended without the prior written consent of Furukawa, and (iii)
Furukawa and its Affiliates will be allowed to acquire, directly or indirectly,
shares in or assets of Persons owning Exchangeable Shares or Uniphase Common
Shares without causing Furukawa or any such Affiliate to become an "Acquiring
Person", provided that Furukawa and its Affiliates agree to sell such
Exchangeable Shares or Uniphase Common Shares within 180 days of completion of
the acquisition in which they are acquired.

SPECIAL VOTING SHARE

    The Special Voting Share will be authorized for issuance pursuant to the
Merger Agreement and, pursuant to the Plan of Arrangement, the Special Voting
Share will be issued to the Trustee appointed under the Voting and Exchange
Trust Agreement. The Special Voting Share will be a preferred share of JDS
Uniphase and will have a par value of U.S.$0.001 per share. Except as otherwise
required by law or the Uniphase Charter, the Special Voting Share will be
entitled to a number of votes equal to the number of outstanding Exchangeable
Shares from time to time not owned by Uniphase and its Affiliates, which votes
may be exercised for the election of directors and on all other matters
submitted to a vote of Uniphase Stockholders. The holders of Uniphase Common
Shares and the holder of the Special Voting Share will vote together as a single
class on all matters, except to the extent voting as a separate class is
required by applicable law or the Uniphase Charter. The holder of the Special
Voting Share will not be entitled to receive dividends from Uniphase and, in the
event of any liquidation, dissolution or winding-up of Uniphase, will receive an
amount equal to the par value thereof. At such time as there are no Exchangeable
Shares outstanding not owned by Uniphase and its Affiliates, and there are no
shares of stock, debt, options or other agreements of Exchangeco that could give
rise to the issuance of any Exchangeable Shares to any person (other than
Uniphase and its Affiliates), the Special Voting Share will be cancelled. See
"Description of Exchangeable Shares -- Voting, Dividend and Liquidation Rights".

DELAWARE LAW AND CERTAIN CHARTER PROVISIONS

    The following is a summary of certain aspects of Delaware law and certain
provisions of the Uniphase Charter.

PROHIBITION ON CERTAIN BUSINESS COMBINATIONS

    Uniphase is subject to the provisions of section 203 of the DGCL. In
general, section 203 prohibits a publicly-held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
a prescribed manner or unless the interested stockholder acquired at least 85%
of the corporation's voting shares (excluding shares held by certain

                                      S-98

designated stockholders) in the transaction in which it became an interested
stockholder. For purposes of section 203, a "business combination" includes a
merger, asset sale or other transaction resulting in a financial benefit to the
interested stockholder. Subject to certain exceptions, an "interested
stockholder" is a person who, together with affiliates and associates, owns, or
within the previous three years did own, 15% or more of the corporation's voting
shares. See "Comparison of Shareholder Rights -- Anti-Takeover Provisions and
Interested Stockholders".

LIMITATIONS OF LIABILITY AND INDEMNIFICATION OF DIRECTORS

    The Uniphase Charter and Uniphase Bylaws contain certain provisions relating
to the limitation of liability and indemnification of directors and officers.
The Uniphase Charter provides that Uniphase's directors may not be held
personally liable to Uniphase or its stockholders for monetary damages for a
breach of fiduciary duty, except for liability (i) for any breach of the
director's duty of loyalty to Uniphase or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under section 174 of the DGCL, relating to prohibited
dividends, distributions and repurchases or redemptions of shares, or (iv) for
any transaction from which the director derives an improper benefit. However,
such limitation does not limit the availability of non-monetary relief in any
action or proceeding against a director. In addition, the Uniphase Charter and
Uniphase Bylaws provide that Uniphase shall indemnify its directors and officers
to the fullest extent authorized by Delaware law.

ELECTION OF DIRECTORS

    The Uniphase Charter provides that, so long as the Uniphase Board of
Directors consists of more than two directors, the Uniphase Board of Directors
will be divided into three classes of directors serving staggered three-year
terms. As a result, approximately one-third of the Uniphase Board of Directors
are elected each year.

MEETINGS OF STOCKHOLDERS

    The Uniphase Charter provides that stockholders can take action only at a
duly called annual or special meeting of stockholders. The Uniphase Charter
prohibits Uniphase Stockholders from taking action by written consent in lieu of
a meeting. In addition, the Uniphase Charter provides that, subject to the
rights of the holders of any shares having a preference over the Uniphase Common
Shares as to dividends or liquidation, special meetings of the stockholders can
be called only by the Uniphase Board of Directors, the Chairman of the Board or
the Chief Executive Officer of Uniphase. Stockholders are not permitted to call
a special meeting or to require the Uniphase Board of Directors to call a
special meeting of stockholders. These provisions may have the effect of
deterring hostile takeovers or delaying changes in control or management of
Uniphase.

                              BUSINESS OF UNIPHASE

GENERAL

    Uniphase designs, develops, manufactures and markets components and modules
for fiberoptic telecommunications and CATV systems and laser subsystems for
various industrial applications. Uniphase was incorporated in 1979 and became a
Delaware corporation in October 1993 at the time of its initial public offering.
Uniphase's telecommunications and CATV divisions design, develop, manufacture
and market semiconductor lasers, high-speed external modulators, transmitters,
modules and other component products for fiberoptic networks in various
telecommunications markets. Uniphase's laser division designs, develops,
manufactures and markets laser subsystems for a broad range of applications
which include biotechnology, industrial process control and measurement,
graphics and printing, and semiconductor equipment.

    Uniphase's original products consisted of laser subsystems for various
industrial applications, including biotechnology, semiconductor wafer
inspection, graphics and printing. As the market for laser based, optoelectronic
telecommunications systems began to develop with the deployment of long
distance, fiberoptic networks in the early 1990s, Uniphase began to shift its
focus in an effort to utilize its existing skills in laser technology in these
new product markets.

    Uniphase entered the telecommunications market in May 1995 through its
acquisition of United Technologies Photonics, then a wholly-owned subsidiary of
United Technologies Research Center located in Hartford, Connecticut. Currently,
Uniphase's portfolio of telecommunications products includes those produced by a
number of Uniphase divisions which include Uniphase Telecommunications Products,
Inc. ("UTP"), UTP -- Transmission Systems Division ("TSD"), UTP Fibreoptics
Limited ("UFP"), Uniphase Laser Enterprise AG ("ULE"), Uniphase Network
Components ("UNC"), Uniphase Fiber Components Pty Limited ("UFC"), UNL, Chassis
Engineering, Inc. ("UTP-Chassis") and Uniphase Broadband Products, Inc. ("UBP").
The following table summarizes the operations of Uniphase and its divisions in
telecommunications

    In December 1998, Uniphase sold the assets of its Ultrapointe semiconductor
capital equipment division and terminated these operations. As a result,
Uniphase will not generate revenue from the sale of semiconductor capital
equipment after December 31, 1998.

TELECOMMUNICATIONS COMPONENTS, MODULES AND OTHER COMPONENTS

    Uniphase supplies a number of the key optoelectronic "active" components
used in telecommunications networks. An "active" component is a device that has
both optical and electronic properties and is different from a "passive"
component, which performs its functions only in the optical domain. Generally,
"active" components provide the source and amplification power and modulation to
these fiberoptic networks while the "passive" components are used to mix,
filter, adjust and stabilize the optical signals in these advanced networks. As
the performance of these networks increases to meet the significant demand for
increased bandwidth and capacity, the interaction between passive and active
components becomes more critical in achieving the increased speed, performance
and reliability of the network. These components are purchased by the OEM system
or subsystem providers, who in turn ultimately supply these systems to the
telecommunications carriers such as AT&T, MCI WorldCom and Sprint.

                                     S-103

    Demands for increased capacity in fiberoptic networks have led to a
proliferation of the methods of transmitting multiple signals at slightly
different wavelengths through a single fiber to achieve higher speed and network
capacity. This technique, which is called wavelength division multiplexing
("WDM"), requires separate source lasers emitting slightly different wavelengths
for each signal or "channel" and more complex modulators and optical amplifiers
to control and amplify the signal in the network. WDM systems, which were
designed for eight separate wavelengths or "channels" in 1996, are currently
being developed to carry as many as 128 separate channels with 0.4 of a
nanometer ("nm") in wavelength differentiation between channels. This increasing
complexity of WDM systems and the decreasing product life cycles of these
rapidly changing network systems have increased the need of the OEM system
suppliers to rely on third party "merchant" suppliers, such as Uniphase and JDS,
to supply higher performance, more complex, more integrated combinations of
active and passive components in shorter time periods to meet their customers'
needs.

    "Active" optoelectronic components such as those made by Uniphase perform
three primary functions within fiberoptic networks. At the beginning of the
network, a "source" laser powers the initial signal that will be transmitted
over the network. These "source" lasers are characterized by their wavelength
and power levels and operate at the 1550-nm wavelength range for general
telecommunications networks and 1310-nm or 1550-nm for CATV telecommunications
networks. Power, which is measured in milliwatts ("mw"), generally determines
the ability of the source laser to transmit over longer distances, with higher
mw source lasers enabling greater initial transmission distances. A single
source laser is required for each channel in a WDM system. The second key
optoelectronic component is the modulator, which generally turns the source
laser light "on" and "off" to encode and send the information throughout the
network. Modulation can be achieved directly by turning the laser light source
"on" and "off" and by external modulators that transmit or alternate a
continuous source laser signal to achieve the same "on" and "off" effect. Lower
performance shorter distance network systems are better suited for direct
modulation, while other systems are designed to utilize external modulators to
encode the information signal. The third key "active" component is the "pump"
laser, which is used in optical amplifiers within networks to regenerate the
light signal that naturally suffers "loss" over distance within the network. The
advent of the optical amplifier in the early 1990s has permitted the development
of today's advanced fiberoptic networks by eliminating the need within those
networks to convert attenuated optical signals back into the electrical domain
to amplify these signals for continued transmission over distances now exceeding
600 kilometres.

    Uniphase's current principal telecommunication products consist of the
following:

    SOURCE LASERS.  Uniphase supplies both 1550-nm and 1310-nm diode lasers as
sources for telecommunications and CATV transmitters. These lasers are either
continuous wave ("cw") for use with external modulators or directly modulated.
For long-haul WDM systems, lasers at up to 20 mw of power are produced to
operate at the many desired optical wavelengths and used in conjunction with 2.5
and 10 gigabit per second ("Gb/s") lithium niobate modulators. Directly
modulated 2.5 Gb/s lasers are used for short-reach fiberoptic systems. For CATV,
higher power (60 mw) 1550-nm cw lasers are used for externally modulated trunk
transmitters and directly modulated 1310-nm analog lasers are used for
distribution transmitters.

    EXTERNAL MODULATORS.  Uniphase produces both of the two types of external
modulators used in long-haul fiberoptic communication systems. Uniphase provides
lithium niobate external modulators used in conjunction with cw lasers and
semiconductor electroabsorption modulators, which are integrated on a chip with
a diode laser. The use of external modulation enables very high channel count
systems (systems with up to 128 channels are in development) and very long (1000
km) propagation distances. Lithium niobate devices are widely used for highest
performance WDM systems such as long-haul 2.5 Gb/s, submarine and 10 Gb/s
terrestrial networks. Uniphase also provides lithium niobate devices for use in
externally modulated CATV trunk transmitters.

    AMPLIFIER "PUMP" LASERS.  Uniphase supplies "pump" lasers that are used to
power the optical amplifier used in fiberoptic systems. Optical amplifiers each
contain from one to six pump lasers depending on amplifier performance
requirements. Two types of pump lasers are used: those that operate at 980-nm
and those at 1480-nm. Uniphase produces both types of pump lasers. These pumps
are used to energize the erbium-doped fiber that comprises the amplifier. Output
power from the pump modules is in the range of 70 to 200 mw. Optical amplifiers
are commonly used in 1550-nm fiber systems that exceed 60 km in length. The
trend in deployment of WDM OC-48 (2.5 Gb/s) and OC-192 (10 Gb/s) of ever rising
channel counts is greatly increasing

                                     S-104

the number of pump lasers deployed. Pump lasers must be highly reliable and, in
1998, Uniphase began shipping the first 980-nm lasers meeting reliability
standards for submarine deployment.

    WAVELENGTH LOCKER MODULES.  Uniphase produces wavelength locker modules that
are used to stabilize the wavelength of lasers used in dense WDM transmission
systems. These lockers ensure that, over the lifetime of the system, the
wavelength of a source laser does not "drift" to interfere with an adjacent
wavelength channel. The locker operates by filtering and detecting a small
amount of the source-laser light and providing a stabilizing feedback signal to
the laser.

    CATV TRANSMITTERS AND AMPLIFIERS.  In CATV networks, Uniphase supplies
transmitters, which are modules combining a number of components that produce
the optical signals running through the networks, and optical amplifiers.
Principal CATV applications are externally modulated transmitters for trunk-line
applications, directly modulated transmitters for the distribution portion of
CATV network, return-path lasers for interactive communications and transmitters
permitting both analog and digital signals to the recipient. Externally
modulated transmitters operate at the preferred optical wavelength of 1550-nm
and incorporate high power source lasers and modulators for the transmission of
broadcast television signals over long distances. Directly modulated
transmitters are typically deployed at the neighborhood node of the CATV network
using either 1310-nm or a low-cost 1550-nm transmitter. Return path lasers allow
cable operators to upgrade existing networks for two-way communications.
Uniphase's transmitters are designed for use in broadband systems, are
operational over bandwidths of up to 1 Ghz and are compatible with hybrid fiber
coax ("HFC") systems being developed by certain telecommunications service
providers for the transmission of voice, data and video. Optical amplifiers
supplied by Uniphase are used in the trunking (backbone) portion of CATV
networks. These trunking lines are typically 50-100 km in length and operate at
1550-nm. Uniphase also supplies amplifiers that are deployed at the distribution
portion of some CATV networks, particularly in international installations.

    FIBER BRAGG GRATINGS AND MODULES.  Uniphase has developed and supplies
certain fiber Bragg grating products, which are devices used to filter and
separate optical signals of different wavelengths in the same fiber. Fiber Bragg
gratings are achieving widespread application within dense WDM optical networks
for both terrestrial and submarine systems. Fiber gratings enable
high-performance, cost-effective solutions that will separate, filter and route
WDM channels in current and future telecommunications systems. Current
applications include channel add-drop, gain flattening, dispersion compensation
and signal monitoring. As the use of fiberoptic systems expands to include metro
and inter-office links, fiber gratings will have increased application as the
need to direct and filter light off a long-haul link in mid-span grows in
importance. In combination with other passive components, fiber gratings provide
an efficient optical-to-optical means of enabling that routing.

    TELECOMMUNICATIONS MODULES AND INSTRUMENTS.  Uniphase provides a number of
specialty products for multi-gigabit fiberoptics systems. In particular,
Uniphase provides some of the transmit/receive ("Tx/Rx") instrumentation modules
used to design and test such systems. Also provided are a variety of
variable-bit rate receivers and OC-48 Tx/Rx products that operate over extended
temperature ranges.

    DATA COMMUNICATIONS DEVICES.  The ever-increasing use of computer networks
is fuelling a growth in fiber data communications systems. Fiber offers
advantages over copper-wire links that include longer distance transmission,
higher data rates, ease of multiplexing, and immunity from electromagnetic
interference. Uniphase offers custom packaged optical sources and detectors for
a variety of fiber-based data communications applications including Gigabit
Ethernet.

LASER SUBSYSTEMS

    Uniphase's principal laser subsystem products consist of air-cooled argon
gas laser subsystems, which primarily emit blue or green light, Helium Neon
("He-Ne") laser subsystems, which primarily emit red or green light, and solid
state lasers, which most often emit infrared, blue or green light. These systems
consist of a combination of a laser head containing the lasing medium, power
supply, cabling and packaging, including heat dissipation elements. Laser
subsystem applications include biotechnology instruments, wafer inspection
systems, graphics and printing systems.

                                     S-105

    Sales of Uniphase argon gas lasers have increased in recent years primarily
as a result of increased sales of such products for use in biotechnology and
semiconductor inspection applications. Use of He-Ne gas lasers has substantially
declined as most customers are now using semiconductor diode lasers to satisfy
bar code scanning applications. Through the acquisition of UNL, Uniphase
obtained manufacturing capability of a semiconductor visible laser used in
high-speed printing and certain multimedia applications.

    Solid state lasers are smaller, use less power and are expected to be the
primary laser technology in the future as compared to conventional gas lasers.
Current applications for Uniphase's solid state lasers include DNA sequencing,
direct-to-plate printing, flow cytometry, particle counting, spectrometry and
semiconductor wafer inspection.

SALES AND MARKETING

    Uniphase markets its telecommunications components to OEMs through its
direct sales force in San Jose, California; Bloomfield, Connecticut; Chalfont,
Pennsylvania; Melbourne, Florida; Switzerland; the Netherlands; Australia; and
the United Kingdom. In addition, Uniphase sells its products through
distributors in selected European countries, Japan, Taiwan, Korea and India.
Selected OEM customers for telecommunications products include:


                                                      
Alcatel                       GPT                           Nortel
Ciena                         Hewlett-Packard               Pirelli
Fujitsu                       Lasertron                     Scientific Atlanta
General Instruments           Lucent                        Siemens


    Uniphase markets its laser subsystem products principally to OEMs through
its own sales force in the United States, United Kingdom and Germany and through
a worldwide network of representatives and distributors to service smaller
domestic accounts, including those in the research and education markets. In
fiscal 1998 and until the sale of the Ultrapointe division to KLA-Tencor on
December 31, 1998, Uniphase marketed its Ultrapointe semiconductor capital
equipment systems primarily through KLA-Tencor's worldwide distribution channels
under an exclusive distribution agreement.

CUSTOMER SUPPORT AND SERVICE

    Uniphase believes that a high level of customer support is necessary to
successfully develop and maintain long term relationships with its OEM customers
in its telecommunications and laser subsystems businesses. These close
relationships begin at the design-in phase and are maintained as customer needs
change and evolve. Uniphase provides direct service and support to its OEM
customers through its offices in the United States and Europe. In Japan,
Uniphase's laser subsystems distributor, Autex, assists in performing support
and service functions.

RESEARCH AND DEVELOPMENT

    During the fiscal years ended June 30, 1998, 1997 and 1996, Uniphase
incurred expenses of U.S.$14.9 million, U.S.$9.9 million and U.S.$6.4 million,
respectively, relating to research and development. In fiscal 1998, 1997 and
1996, Uniphase recorded charges totalling U.S.$40.3 million, U.S.$33.3 million
and U.S.$4.5 million, respectively, for acquired IPRD in connection with the
acquisitions of UNL and UFC in 1998, ULE in 1997 and UFP in 1996.

    Uniphase is developing new and enhanced telecommunications components and
expanding its manufacturing capability for these products. For example, Uniphase
continues to increase the power output of its pump lasers and the power and
wavelength distribution of source lasers available for multi-channel WDM
applications. Higher performance transmitters are under development, as are
advanced, high speed modulators. Uniphase continues to develop packaging
technology for a number of its optoelectronic components so as to enable it to
supply integrated, packaged modules to its customer base. Uniphase continues to
invest in solid state laser applications for industrial processes and wafer
defect review capabilities for higher density semiconductor devices.

purchasing, materials management, assembly, final testing and quality assurance
functions at each location for the products that are manufactured at that
facility.

COMPETITION

    The industries in which Uniphase sells its products are highly competitive.
Uniphase's overall competitive position depends upon a number of factors,
including the price and performance of its products, the level of customer
service and quality of its manufacturing processes, the compatibility of its
products with existing laser systems and Uniphase's ability to participate in
the growth of emerging technologies.

    Competitive factors in the market for Uniphase's telecommunications
equipment products include price, product performance and reliability, the
capability to provide strong customer support and service, customer
relationships, the breadth of product line and, in some cases, timely increased
production capacity. In this market, Uniphase faces competition from companies
that have substantially greater financial, engineering, research, development,
manufacturing, marketing, service and support resources, greater name
recognition than Uniphase and long-standing customer relationships. With respect
to source lasers and pump lasers for telecommunications applications,
competitors include Fujitsu, Pirelli, Furukawa, Alcatel, Nortel, Lucent and SDL,
Inc. With respect to external modulator products for CATV and telecommunications
suppliers, competitors include Lucent Technologies, Fujitsu, Integrated Optical
Components, Ltd. ("IOC") and Sumitomo Cement Opto Electronics Group. In March
1999, SDL, Inc. and IOC announced that the board of directors of IOC agreed to
recommend that shareholders approve an offer to be made by SDL, Inc. to acquire
all of the shares of IOC. With respect to 1310-nm and 1550-nm CATV transmitters,
competitors include Harmonic Lightwaves Inc., Ortel Corporation and Synchronous
Communications. Other CATV equipment suppliers may also enter this industry.
With respect to fiber Bragg gratings and grating-based modules, competitors
include Lucent, E-Tek and Corning. With respect to laser diode products for data
communications and local telecommunications suppliers, Uniphase's competitors
include Oz Optics Ltd. and SDL-Optics, Inc. as well as larger optoelectronic
suppliers such as AMP and Hewlett-Packard Company.

    In the laser subsystems industry, Uniphase competes primarily with American
Laser, Coherent Communications Systems Corporation, Ion Laser Technology, NEC,
Omnichrome, Spectra-Physics, Toshiba, Carl Zeiss, Melles-Griot, Hitachi,
Lightwave, Opto Power Corporation, SDL, Inc., Siemens and Sony.

PATENTS AND PROPRIETARY RIGHTS

    Intellectual property rights that apply to various Uniphase products include
patents, trade secrets and trademarks. Because of the rapidly changing
technology and a broad distribution of patents in the optoelectronics industry,
Uniphase's intention is not to rely primarily on intellectual property rights to
protect or establish its market position. Uniphase does not intend to broadly
license its intellectual property rights unless it can obtain adequate
consideration or enter into acceptable patent cross-license agreements. Uniphase
holds approximately 100 United States patents and access to 295 corresponding
foreign patents on technologies related to its products and processes. The
United States patents expire on dates ranging from 1999 to 2016.

                                     S-107

EMPLOYEES

    At March 31, 1999, Uniphase had a total of 1,268 full-time employees
worldwide, including 221 in research, development and engineering, 73 in sales,
marketing and service, 822 in manufacturing, and 152 in general management,
administration and finance. Uniphase's future success will depend in part on its
ability to attract, train, retain and motivate highly qualified employees, who
are in great demand. There can be no assurance that Uniphase will be successful
in attracting and retaining such personnel. Except for its Netherlands
operations, Uniphase's employees are not represented by any collective
bargaining organization. Most hourly and salaried employees in the Netherlands
are represented by the Philips collective labor agreement. Uniphase has never
experienced a work stoppage, slowdown or strike. Uniphase considers its employee
relations to be good.

LEGAL PROCEEDINGS

    In the ordinary course of business, various lawsuits and claims are filed
against Uniphase. While the outcome of these matters is currently not
determinable, management believes that the ultimate resolution of these matters
will not have a material adverse effect on Uniphase's business, financial
condition or operating results.

(1) Except in the event of a change in control of Uniphase, options granted
    become exercisable at the rate of 25% of the shares subject thereto one year
    from the grant date and as to approximately 6.25% of the shares subject to
    the option at the end of each three-month period thereafter such that the
    option is fully exercisable four years from the grant date. The Transaction
    does not result in a change of control of Uniphase.

(2) Based on a total of 2,004,722 options granted to employees of Uniphase in

(3) The potential realizable value is calculated based on the term of the option
    at its time of grant. It is calculated assuming that the stock price on the
    date of grant appreciates at the indicated annual rate, compounded annually
    for the entire term of the option, and that the option is exercised and sold
    on the last day of its term for the appreciated stock price.

COMPENSATION OF DIRECTORS

    Directors who are employees of Uniphase do not receive any compensation for
their services as directors. Directors who are not employees of Uniphase receive
a U.S.$1,500 fee for attendance at each board meeting and a U.S.$500 fee for
attendance at committee meetings held on a separate day. All directors are
reimbursed for expenses incurred in connection with attending board and
committee meetings.

    The Uniphase 1993 Plan also provides for automatic grants of nonqualified
stock options to non-employee or outside directors. In general, under the
Uniphase 1993 Plan, each outside director who first joins the board after the
effective date of the Uniphase 1993 Plan automatically will receive at that time
an option to purchase 40,000 Uniphase Common Shares. In addition, immediately
after each annual meeting of stockholders, each individual who is at that time
continuing to serve as an outside director automatically will be granted an
option to purchase 10,000 additional Uniphase Common Shares, whether or not such
outside director stood for re-election at such annual meeting, provided that
each such individual has served as an outside director for at least nine months.
All options granted under the Uniphase 1993 Plan prior to September 1996 to
outside directors have an exercise price equal to 100% of the fair market value
of the Uniphase Common Shares on the date of grant and vest at the rate of 25%
of the shares subject to the option at the end of the first year and as to
approximately 6.25% of the shares subject to the option each quarter
(three-month period) for twelve quarters thereafter, and terminate five years
from the date of granting. All options granted to outside directors subsequent
to September 1996 under the Uniphase 1993 Plan have an exercise price equal to
100% of the fair market value of the Uniphase Common Shares on the date of grant
and vest monthly on a straight-line basis over a three-year period for the
initial 40,000 shares granted upon joining the Uniphase Board of Directors and
over twelve months for the subsequent grants of 10,000 shares, and terminate
eight years from the date of grant. Mr. Haverkamp received no shares upon
joining the Uniphase Board of Directors.

    In fiscal 1998, Dr. Bridges, Mr. Fink, Mr. Johnson, Ms. Lego, Mr. Muller and
Professor Sibbett were each granted options to purchase 10,000 Uniphase Common
Shares at a price of U.S.$33.00 per share. Mr. Muller resigned from the Uniphase
Board of Directors upon his appointment as Senior Vice President, Chief
Financial Officer and Secretary of Uniphase in January 1998. Dr. Bridges
resigned from the Uniphase Board of Directors in April 1998 and is now a member
of the Uniphase scientific advisory board.

COMPENSATION COMMITTEE REPORT

    Notwithstanding anything to the contrary set forth in any of Uniphase's
previous filings under the Securities Act or the Exchange Act that might
incorporate future filings, including this Supplement, in whole or in part, the
following report and the performance graph which follows shall not be deemed to
be filed with the SEC nor be incorporated by reference into any such filings and
is provided for informational purposes only.

    The compensation committee of the Uniphase Board of Directors is responsible
for establishing the base salary and incentive cash bonus programs for Uniphase
executive officers and administering certain other

                                     S-112

compensation programs for such individuals, subject in each instance to approval
by the full board. The compensation committee also has the exclusive
responsibility for the administration of the Uniphase Option Plans under which
grants may be made to executive officers and other key employees.

    The fundamental policy of the compensation committee is to provide the chief
executive officer and executive vice presidents of Uniphase with competitive
compensation opportunities based upon their contribution to the financial
success of Uniphase and their personal performance. It is the compensation
committee's objective to have a substantial portion of each officer's
compensation contingent upon Uniphase's performance as well as upon his own
level of performance. Accordingly, the compensation package for the chief
executive officer and executive vice presidents is comprised of three elements:
(i) base salary which reflects individual performance and is designed primarily
to be competitive with salary levels in the industry, (ii) annual variable
performance awards payable in cash and tied to Uniphase's achievement of
financial performance targets, and (iii) long-term stock-based incentive awards
which strengthen the mutuality of interests between the executive officers and
Uniphase's stockholders. As an executive officer's level of responsibility
increases, it is the intent of the compensation committee to have a greater
portion of his total compensation be dependent upon Uniphase's performance and
stock price appreciation rather than base salary.

    Several of the more important factors which the compensation committee
considered in establishing the components of each executive officer's
compensation package for fiscal 1998 are summarized below. Additional factors
were also taken into account and the compensation committee may in its
discretion apply entirely different factors, particularly different measures of
financial performance, in setting executive compensation for future fiscal
years.

    BASE SALARY.  The base salary for each officer is determined on the basis of
the following factors: experience, personal performance, the average salary
levels in effect for comparable positions within and without the industry and
internal comparability considerations. The weight given to each of these factors
differs from individual to individual, as the compensation committee deems
appropriate. In selecting comparable companies for the purposes of maintaining
competitive compensation, the compensation committee considers many factors
including geographic location, growth rate, annual revenue and profitability,
and market capitalization. The compensation committee also considers companies
outside the industry which may compete with Uniphase in recruiting executive
talent.

    ANNUAL INCENTIVE COMPENSATION.  Annual bonuses are earned by each executive
officer primarily on the basis of Uniphase's achievement of certain corporate
financial performance goals established for each fiscal year. For fiscal 1998,
bonuses were earned on the basis of the following factors: (i) Uniphase's
consolidated operating profit performance net of certain non-recurring
adjustments, relative to the target established by the compensation committee,
and (ii) the revenue and operating profit performance of the respective division
or subsidiary relative to the targets established by the compensation committee.
A portion of Uniphase's earnings for the 1998 fiscal year was accordingly set
aside for distribution under the bonus pool, and the chief executive officer and
each executive vice president was awarded a share of that pool on the basis of
the respective responsibilities assigned to him and his relative position with
Uniphase. The actual bonus paid in fiscal 1998 to each of the Named Executive
Officers is indicated in the Bonus column of the Summary Compensation Table
under the heading "Business of Uniphase -- Executive Compensation".

    DEFERRED COMPENSATION PLAN.  Uniphase maintains a deferred compensation
plan, pursuant to which certain members of management (including the executive
officers) may elect to defer a portion of his or her annual compensation. The
participants' funds are invested among various funds designated by the plan
administrator and currently may not be invested in Uniphase Common Shares or
other Uniphase securities. Upon the death or retirement of a participant, the
funds attributable to the participant (including any earnings on contributions)
are distributed to the participant or the participant's beneficiary in a lump
sum or in annual instalments over a period of three, five, ten or 15 years.

    LONG-TERM COMPENSATION.  Long-term incentives are provided through stock
option grants. The grants are designed to align the interests of each executive
officer with those of the stockholders and provide each individual with a
significant incentive to manage Uniphase from the perspective of an owner with
an equity stake in the business. Each grant allows the individual to acquire
Uniphase Common Shares at a fixed price per share

                                     S-113

(the market price on the grant date) over a specified period of time (up to ten
years). Options granted become exercisable at the rate of 25% of the shares
subject thereto one year from the grant date and as to approximately 6.25% of
the shares subject to the option at the end of each three-month period
thereafter such that the option is fully exercisable four years from the grant
date, contingent upon the executive officer's continued employment with
Uniphase. Accordingly, the option will provide a return to the executive officer
only if the executive officer remains employed by Uniphase during the four-year
vesting period, and then only if the market price of the underlying shares
appreciates over the option term. The number of shares subject to each grant is
set at a level intended to create a meaningful opportunity for stock ownership
based on the officer's current position with Uniphase, the base salary
associated with that position, the average size of comparable awards made to
individuals in similar positions within the industry, the individual's potential
for increased responsibility and promotion over the option term, and the
individual's personal performance in recent periods. The compensation committee
also takes into account the number of vested and unvested options held by the
executive officer in order to maintain an appropriate level of equity incentive
for that individual. However, the compensation committee does not adhere to any
specific guidelines as to the relative option holdings of Uniphase executive
officers. The actual options granted to each of the Named Executive Officers is
set forth in the Long-Term Compensation Awards column of the Summary
Compensation Table under the heading "Business of Uniphase -- Executive
Compensation".

    COMPENSATION OF THE CHIEF EXECUTIVE OFFICER.  The compensation of the Chief
Executive Officer is reviewed annually on the same basis as discussed above for
all executive officers. Mr. Kalkhoven's base salary for the fiscal year ended
June 30, 1998 was U.S.$274,835. Mr. Kalkhoven's base salary was established in
part by comparing the base salaries of chief executive officers of other
companies of similar size. Mr. Kalkhoven's base salary was at the approximate
median of the base salary range for presidents/chief executive officers of
comparative companies. Mr. Kalkhoven's bonus for fiscal 1998 was 65% of his base
salary and was contingent on Uniphase meeting its pre-bonus, net operating
income and revenue targets for fiscal 1998. Based on these criteria, which are
the same criteria applied to all executive officers as described above, for
fiscal 1998 Mr. Kalkhoven was awarded a bonus of U.S.$177,615 as well as options
to purchase 320,000 Uniphase Common Shares.

    Uniphase is required to disclose its policy regarding qualifying executive
compensation for deductibility under section 162(m) of the Code which provides
that, for purposes of the regular income tax and the alternative minimum tax,
the otherwise allowable deduction for compensation paid or accrued with respect
to a covered employee of a publicly-held corporation is limited to no more than
U.S.$1 million per year. It is not expected that the compensation to be paid to
Uniphase's executive officers for fiscal 1998 will exceed the U.S.$1 million
limit per officer. The Uniphase 1993 Plan is structured so that any compensation
deemed to be paid to an executive officer when he exercises an outstanding
option under such plan, with an exercise price equal to the fair market value of
the option shares on the grant date, will qualify as performance-based
compensation which will not be subject to the U.S.$1 million limitation.

                 UNIPHASE MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

    Uniphase designs, develops, manufactures and markets components and modules
for fiberoptic telecommunications and CATV systems and laser subsystems.
Uniphase was incorporated in 1979 and became a Delaware corporation in October
1993 at the time of its initial public offering. Uniphase's telecommunications
and CATV divisions design, develop, manufacture and market semiconductor lasers,
high-speed external modulators, transmitters and other components and products
for fiberoptic networks in various telecommunications markets. Uniphase's laser
division designs, develops, manufactures and markets laser subsystems for a
broad range of applications which include biotechnology, industrial process
control and measurement, graphics and printing and semiconductor equipment.

    Uniphase manufactures its optoelectronic telecommunications component and
module products at its owned and leased facilities in the United States, Europe
and Australia. Its laser subsystem products are manufactured at two facilities
located in California. Uniphase has approximately 1,300 employees world-wide.
For its fiscal year ended June 30, 1998, Uniphase had net sales of U.S.$119.6
million from telecommunications components and modules, which represented
approximately 64.6% of its total net sales. The balance of net sales for fiscal
1998 were derived from laser subsystems, which accounted for U.S.$46.3 million
in net sales in fiscal 1998, and from Uniphase's Ultrapointe product line, which
it sold in December 1998 with the result that such product line ceased to
provide a source of continuing revenue after the quarter ended December 31,
1998.

RECENT EVENTS

    In June 1998, Uniphase acquired 100% of the capital stock of Philips
Optoelectronics B.V., which became UNL, from Philips. The total purchase price
of U.S.$135.4 million consisted of 3.26 million unregistered restricted Uniphase
Common Shares, cash of U.S.$100,000, U.S.$4.0 million in related acquisition
costs, and 100,000 shares of Uniphase Series A Preferred Shares that are
convertible to Uniphase Common Shares based upon (i) unit shipments of certain
products by UNL through June 20, 2002, and (ii) the trading price of Uniphase
Common Shares at the time such earnout, if any, is determined and which could
increase the purchase price by a maximum of approximately U.S.$285 million. At
the closing of the UNL acquisition, Philips became the largest stockholder of
record at 8.5% of the Uniphase Common Shares. Philips also appointed one
representative to the Uniphase Board of Directors upon the closing of that
transaction.

    On November 25, 1998, Uniphase acquired BCP through the issuance of
approximately 730,000 Uniphase Common Shares in a transaction accounted for as a
pooling of interests. BCP will operate as Uniphase Broadband Products, Inc.
("UBP"). UBP manufactures high-speed and high-bandwidth fiberoptic products
including transmitters, receivers and multiplexers used to extend the reach of
fiberoptic transmission into metropolitan and local access networks. Results for
the second quarter include U.S.$5.9 million of costs associated with this
merger. This Management's Discussion and Analysis reflects the pooled entity.

    On December 31, 1998, Uniphase sold substantially all of the assets of its
Ultrapointe subsidiary to KLA-Tencor Corporation ("KLA-Tencor") and recognized a
pre-tax charge of U.S.$882,000 and a charge to cost of sales of U.S.$1.6 million
in connection with the transaction.

    On January 28, 1999, Uniphase announced the signing of the Merger Agreement
providing for the Transaction with JDS. The Transaction will be accounted for as
a purchase transaction and is subject to a number of contingencies including
approval by JDS Shareholders and Uniphase Stockholders and certain closing
conditions, including regulatory approvals. Uniphase anticipates that a
significant portion of the purchase price will result in the recognition of
intangible assets of approximately U.S.$3.2 billion in the period of
consummation, thereby resulting in a net loss in the foreseeable future due to
the amortization of such intangibles.

    Uniphase's acquisitions of UNL, UFC and Chassis Engineering, Inc. were
accounted for using the purchase method of accounting. Accordingly, the total
purchase price was allocated to the assets acquired and liabilities assumed,
including IPRD based on their estimated fair values using valuation methods
believed to be appropriate at the time. With respect to UNL, the estimated fair
value of the IPRD of U.S.$93.0 million was expensed in the fourth quarter of
fiscal 1998 (the period in which the acquisition was consummated).

                                     S-116

Subsequent to the SEC's letter to the American Institute of Certified Public
Accountants dated September 9, 1998, regarding its views on in-process research
and development, Uniphase has re-evaluated its IPRD charge with respect to the
UNL acquisition, revised the purchase price allocation and restated its
financial statements. As a result, Uniphase made an adjustment to decrease the
amount of previously expensed IPRD and increase the amount capitalized as
goodwill and other intangibles by U.S.$59.3 million.

NINE MONTHS ENDED MARCH 31, 1999 AND 1998

    NET SALES.  For the first nine months of fiscal 1999, net sales were
U.S.$195.7 million, which represented a U.S.$63.2 million or 47% increase over
net sales of U.S.$133.4 million in the same period of fiscal 1998. Increases in
net sales from each of Uniphase's major telecommunications product lines and net
sales generated by Uniphase Netherlands (UNL), which was acquired in June 1998
in a transaction accounted for as a purchase, contributed to the growth in net
sales over the comparable nine month period of fiscal 1998.

    GROSS PROFIT.  For the first nine months of fiscal 1999, gross profit
increased 46% to U.S.$97.0 million or 50% of net sales from $66.5 million or 50%
of net sales in the same period of fiscal 1998. Gross profit for the first nine
months of fiscal 1999 includes a U.S.$1.6 million charge to cost of sales in the
second quarter of fiscal 1999 resulting from the sale of Ultrapointe assets to
KLA-Tencor Corporation.

    RESEARCH AND DEVELOPMENT.  For the first nine months of fiscal 1999,
research and development expense was U.S.$18.8 million or 10% of net sales,
which represented a U.S.$8.4 million or 80% increase over the same period in
fiscal 1998. The increase in R&D expense is primarily due to increased
expenditures associated with the continued development and enhancement of
Uniphase's telecommunications and fiber optic product lines and the addition of
Uniphase Netherlands in June 1998.

    SELLING, GENERAL AND ADMINISTRATIVE.  For the first nine months of fiscal
1999, SG&A expense was U.S.$24.5 million or 13% of net sales which represented a
U.S.$3.2 million or 15% increase over SG&A expense of U.S.$21.3 million or 16%
of net sales in the same period of fiscal 1998. The dollar increase in SG&A
expense for the first nine months of fiscal 1999 as compared to the same period
in the prior year is primarily due to higher sales and marketing costs to
support telecommunications and CATV products and the addition of UNL in June
1998 offset by a reduction in SG&A expense of the Ultrapointe product line.

    AMORTIZATION OF PURCHASED INTANGIBLES.  Since fiscal 1995, Uniphase has
entered into several strategic acquisitions that generated approximately
U.S.$115.0 million in identified intangibles (primarily developed technology)
and goodwill. For the first nine months of fiscal 1999, amortization of
purchased intangibles ("API") was U.S.$11.8 million or 6% of net sales which
represented a U.S.$10.5 million or 775% increase over API of U.S.$1.3 million or
1% of net sales in the same period of fiscal 1998. The increase in API is
primarily due to the intangible assets generated from the acquisition of UNL in
June 1998 and the purchase of certain assets from Chassis Engineering.

    OTHER OPERATING EXPENSES.  For the first nine months of fiscal 1999,
Uniphase recorded pre-tax merger related costs of U.S.$5.9 million in connection
with the acquisition of UBP in a transaction accounted for as a pooling of
interests and a pre-tax loss of U.S.$882,000 on the disposal of substantially
all the assets of its Ultrapointe product line. In the second quarter of fiscal
1998, Uniphase recognized a pre-tax charge of U.S.$6.6 million in acquired IPRD
charges in connection with its acquisition of Indx Pty Ltd. of Australia.

    INTEREST AND OTHER INCOME, NET.  For the first nine months of fiscal 1999,
interest and other income, net increased to U.S.$2.7 million from U.S.$2.3
million in the same period of fiscal 1998. The increase in interest and other
income is primarily the result of interest income on higher levels of
investments.

    INCOME TAXES.  The effective tax rate for the first nine months of fiscal
1999 was 38.2% compared to 41.3% used in the same period of fiscal 1998. A
decrease in the effective tax rate was primarily attributable to an increase in
foreign earnings taxed at a lower rate that are permanently re-invested
offshore. The fiscal 1999 provision for income taxes excludes the effect of
non-deductible merger costs incurred in connection with the acquisition of UBP,
whereas fiscal 1998 amounts exclude the effect of non-deductible acquired IPRD
expenses originating from the acquisition of UFC.

    NET SALES.  Net sales of U.S.$185.2 million for fiscal 1998 represented an
increase of U.S.$72.0 million or 63.6% over fiscal 1997 net sales of U.S.$113.2
million. The increase was primarily due to the increase across all product lines
in telecommunications and laser subsystem sales of U.S.$68.1 million, of which
43.7% was generated by businesses acquired during fiscal 1998 and 1997.
Ultrapointe sales increased U.S.$3.9 million in fiscal 1998 over the prior year,
although a significant percentage of the increase was attributable to orders for
spare parts and engineering services. Net sales of U.S.$113.2 million for fiscal
1997 represented an increase of U.S.$39.5 million or 53.6% over fiscal 1996 net
sales of U.S.$73.7 million. The increase in fiscal 1997 over 1996 was primarily
due to the increased sales of telecommunications and laser subsystem products of
U.S.$41.7 million. Ultrapointe sales decreased U.S.$2.2 million during fiscal
1997 as compared to fiscal 1996 as a downturn in the semiconductor industry led
certain customers to delay or cancel purchases of Uniphase's Ultrapointe Systems
products.

    Net sales to customers outside the United States accounted for U.S.$71.7
million, U.S.$34.6 million and U.S.$18.5 million or 38.7%, 30.6% and 25.1% of
total sales for fiscal, 1998, 1997 and 1996, respectively. The increase of
U.S.$37.1 million from fiscal 1997 to fiscal 1998 was primarily due to increased
sales of telecommunications products. The increase in international sales in
1998 was also due to a full year's sales from ULE, the sales of UFC subsequent
to November 26, 1997, and UNL sales subsequent to June 9, 1998, all of which
represented in the aggregate 35.2% of the increase in international sales. The
fiscal 1997 increase in international sales over fiscal 1996 of U.S.$16.1
million was due primarily to a full year of UFP sales and the acquisition of ULE
in March 1997 combined with other increases in telecommunications product sales.
(See Note 10 of Notes to Uniphase audited financial statements as at and for the
year ended June 30, 1997, which financial statements are not included in this
Supplement.)

    GROSS PROFIT.  Gross profit of U.S.$89.1 million, or 48.1% of net sales for
fiscal 1998 represented an increase of U.S.$35.9 million or 67.5% over fiscal
1997 gross profit of U.S.$53.2 million, which was 47.1% of net sales. The
increase in gross profit from telecommunications and laser subsystem product
sales of U.S.$37.7 million was due in part to an improvement in manufacturing
yields of gallium arsenide based lasers combined with the lower costs of
internally manufactured CATV amplifiers Uniphase historically purchased from
third parties. Fiscal 1998 amounts include a full year's gross profit from ULE
that also contributed to the increase.

    Concurrent with the acquisition of UNL, Uniphase initiated certain actions
that resulted in reductions to fiscal 1998 gross profit. Charges attributable to
such actions were primarily for: (i) inventory write-downs of U.S.$2.5 million
as a result of product overlap of the UNL lasers with some of Uniphase's
existing products, resulting in excess quantities and obsolescence of certain
products; (ii) inventory write-downs of U.S.$1.0 million

                                     S-118

as a result of renegotiating certain provisions of its distribution agreement
with KLA-Tencor to provide reduced quantities of Ultrapointe products, resulting
in excess inventory levels; and (iii) inventory write-downs of U.S.$600,000 as a
result of discontinuing a small specialty product line.

    Gross margin increased to 48.1% in fiscal 1998 from 47.1% in fiscal 1997.
Uniphase realized improved yields on certain telecommunications products that
more than offset a reduction in gross margin from Ultrapointe products. Gross
margin for Ultrapointe products declined significantly in the second half of
fiscal 1998 due to depressed semiconductor equipment markets, volume discounts
attributable to the distribution agreement with KLA-Tencor, and inventory
reserves recorded in the fourth quarter. Uniphase's laser subsystem margins were
relatively consistent with the prior fiscal year. Uniphase experienced a
decrease in gross margins to 47.1% in fiscal 1997 from 48.1% in fiscal 1996.
Inventory charges resulting from Uniphase's change in strategic focus with
respect to diode based laser applications and from the modification of certain
customer and product strategies incorporating lower powered amplifiers at UTP
contributed to the fiscal 1997 decline in gross margin.

    RESEARCH AND DEVELOPMENT EXPENSE.  R&D expense of U.S.$14.9 million or 8.0%
of net sales represented an increase of U.S.$5.0 million or 50.7% over fiscal
1997 expense of U.S.$9.9 million or 8.7% of net sales. The increase in absolute
dollar amounts is primarily due to the continuing efforts to develop Uniphase's
telecommunications products, the additional R&D expenses of UFC and UNC in
fiscal 1998 and a full year of R&D expenses from ULE. R&D expense in fiscal 1997
was U.S.$9.9 million or 8.7% of net sales, which represented a U.S.$3.4 million
or 53.0% increase over fiscal 1996. The increase in R&D expense was largely due
to the continuing efforts to develop Uniphase's telecommunications products and,
to a lesser extent, the continued development and modifications of the
Ultrapointe Laser Imaging System and automatic defect classification software.

    ROYALTY AND LICENSE EXPENSE.  Royalty and license expense increased
U.S.$628,000 to U.S.$2.0 million representing an increase of 45.5% over fiscal
1997 expense of U.S.$1.4 million. Royalty and license expense decreased as a
percentage of sales to 1.1% compared to 1.2% in fiscal 1997. In fiscal 1997,
royalty and license expense increased U.S.$43,000 to U.S.$1.4 million from
U.S.$1.3 million in fiscal 1996, however these same expenses decreased as a
percentage of sales to 1.2% from 1.8% in fiscal 1996. The decreases as a
percentage of net sales in both fiscal 1998 and fiscal 1997 were due to the
increasing proportion of sales derived from royalty-free telecommunications
products.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSE.  SG&A expense of U.S.$43.5
million or 23.5% of net sales in fiscal 1998 represents an increase of U.S.$19.0
million or 77.9% over fiscal 1997 expense of U.S.$24.4 million or 21.7% of net
sales. As described below, SG&A expenses in each year included charges incurred
following acquisitions.

    In the fourth quarter of fiscal 1998, Uniphase recorded SG&A charges related
to certain initiatives taken following the acquisition of UNL. These charges
were for:

    (i) reorganizing Uniphase's management and sales structure primarily
        consisting of (a) U.S.$3.6 million for severance costs related to
        management and other personnel terminated during the quarter of which
        U.S.$2.9 million was a non-cash charge resulting from the acceleration
        of stock option vesting, and (b) an additional U.S.$700,000 in SG&A
        expenses related to costs incurred in connection with centralizing
        Uniphase's sales function included hiring and relocating new sales
        management and training the sales force;

    (ii) integrating the laser packaging operations of UNL into Uniphase of
         which the primary component was an impairment write-down of U.S.$3.6
         million related to the fixed assets and intangible assets recorded in
         connection with the acquisition of UPP in 1996. Because of the product
         overlap between UNL and UPP, the revised projected cash flows of UPP
         would not provide for the recovery of the book value of these assets;

   (iii) providing for the cost of changing the structure of Ultrapointe in
         connection with the continuing downturn in semiconductor equipment
         markets, the primary components of which costs are severance costs
         related to Ultrapointe personnel terminated during the quarter of which
         U.S.$3.9 million was a non-cash charge resulting from the acceleration
         of stock option vesting; and

                                     S-119

    (iv) providing for costs of U.S.$1.1 million incurred in connection with
         obtaining a supply agreement with a major CATV system customer.

Future cash outflows in connection with these actions were estimated to be
U.S.$1.8 million, which is expected to be paid by the end of fiscal 1999.

    In fiscal 1997, SG&A expense was U.S.$24.4 million or 21.7% of net sales,
which represented a U.S.$7.1 million or 41.3% increase over SG&A expense of
U.S.$17.3 million or 23.7% of net sales in fiscal 1996. The increase is due in
part to the additional expenses of ULE, acquired in March 1997, and a full year
of expenses for UFP which was acquired in May 1996. As a result of the ULE
acquisition and a change in strategic focus for diode-based laser applications,
Uniphase recorded charges to consolidate its European laser research to
Switzerland, close its Uniphase Lasers, Ltd. facility in Rugby, England,
consolidate laser packaging operations and to recognize the modification of
certain customer and product strategies at UTP incorporating lower powered
amplifiers. Uniphase also increased its allowance for doubtful accounts and
certain other reserves in the third quarter of fiscal 1997.

    ACQUIRED IPRD.  In fiscal 1998, Uniphase incurred charges for IPRD of
U.S.$40.3 million or 21.7% of net sales related to the acquisition of UNL from
Philips (U.S.$33.7 million) and UFC from AP (U.S.$6.6 million). In fiscal 1997,
Uniphase incurred a charge for IPRD of U.S.$33.3 million or 29.4% of net sales
related to the acquisition of the assets of ULE from IBM. In fiscal 1996,
Uniphase incurred a charge for IPRD of U.S.$4.5 million or 6.1% of net sales
related to the acquisition of UFP. See Note 9 of Notes to Uniphase Audited
Financial Statements. These amounts were expensed on the acquisition dates
because the acquired technology had not yet reached technological feasibility
and had no future alternative uses. There can be no assurance that acquisitions
of businesses, products or technologies by Uniphase in the future will not
result in substantial charges for acquired IPRD that may cause fluctuations in
Uniphase's quarterly or annual operating results.

    A description of the acquired in-process technology, stage of development,
estimated completion costs and time to complete at the date of acquisition is
set forth below for each acquisition.

    Uniphase Netherlands

    The purchased in-process technology related to advanced semiconductor
lasers, modulators, and semiconductor optical amplifiers. The purchased
in-process technology was comprised of five main categories: (i) Wavelength
Division Multiplexing ("WDM") Lasers -- Continuous Wave ("CW") and Direct
Modulation, (ii) WDM Lasers -- Distributed Feedback/Electro-Absorption
Modulator; (iii) Semiconductor Optical Amplifiers, (iv) Other Telecommunications
Products, and (v) Cable Television. The development cycle for the full product
family (portfolio) for each of these technologies, on average, takes
approximately four years to complete. The stages of development for each product
in the portfolio include: (i) idea generation, (ii) design process, (iii) wafer
growth, (iv) chip fabrication, (v) packaging, and (vi) qualification and
testing. Technological feasibility is achieved upon successful completion of
qualification and testing. This stage tests the reliability of the technology
(the most important measure to the end-user).

    The following is a brief description of each acquired IPRD project at the
acquisition date:

    WDM LASERS -- CW AND DIRECT MODULATION.  The portfolio of products within
the WDM market enabled by this technology category includes the 1550nm high
power laser source used in the long haul (600km) dense WDM (DWDM) transmitters
and directly modulated WDM lasers used for shorter (100km) links. The portfolio
also includes the laser portion of integrated laser/electro-absorption
modulators ("EML's").

    Excluding the research phase of the development cycle, Uniphase estimated
that the development time for products in this category was 36 months. At the
time of acquisition, the initial complexity hurdles for the development of these
products had been achieved. The first generation of these products had been
released and the second generation was in the wafer growth development stage and
was estimated to be released in the second half of calendar 1998 with the third
generation of products in the research stage and estimated to be released in
fiscal 2002. At the acquisition date, the estimated costs to complete the
technology in this category was approximately U.S.$8.2 million from the date of
acquisition through fiscal 2002. Uniphase believed the associated risks of
developing this technology into commercially viable products to be the challenge
of meeting the requirements and specifications of the market, in particular with
respect to reliability and customer

                                     S-120

qualification, meeting product packaging standards, and risks related to
semiconductor processing such as the ability to make a qualified product at
commercially acceptable yields.

    WDM LASERS -- DISTRIBUTED FEEDBACK/ELECTRO-ABSORPTION MODULATOR.  The
portfolio of technologies for EA modulators includes EML 1550nm laser sources
which contain an electro-absorption modulator that targets the mid-range (300km)
DWDM transmitters and EMLs laser sources for longer distances (greater than
400km).

    At the time of the acquisition, this portfolio of WDM EML lasers had been in
development for approximately 14 months, excluding the research phase of the
development cycle. The first generation of these products had been released and
the second generation was in the wafer growth development stage and was
estimated to be released in the second half of calendar 1998 with the third
generation of products in the research stage and estimated to be released in
fiscal 2002. At the acquisition date, the estimated costs to complete the
technology in this category was approximately U.S.$16.3 million from the date of
acquisition through fiscal 2002. Uniphase believed the associated risks of
developing this technology into commercially viable products to be the challenge
of meeting the requirements and specifications of the market, in particular with
respect to reliability and customer qualification, meeting packaging standards,
and risks related to semiconductor processing such as the ability to make a
qualified product at commercially acceptable yields.

    SEMICONDUCTOR OPTICAL AMPLIFIERS.  Within this technology category, the
opportunity exists for the development of low power, low cost, semiconductor
optical amplifiers based on indium phosphide and for the development of
different versions which amplify 1550nm light of 1310nm light.

    Prior to acquisition, UNL did not have a developed semiconductor optical
amplifier product, the initial generation of products having not proved to be
viable. However, over 40% of the total research and development budget of UNL
prior to the acquisition had been invested in all technologies in this category.
The second generation of these products was in the wafer growth development
stage and was estimated to be released in fiscal 1999 with the third generation
of products in the research stage and estimated to be released in fiscal 2002.
At the acquisition date, the estimated costs to complete the technology in this
category was approximately U.S.$2.3 million from the date of acquisition through
fiscal 2002. Uniphase believed the associated risks of developing this
technology into commercially viable products to be the challenge of meeting the
requirements and specifications of the market, in particular with respect to
reliability and customer qualification, meeting product packaging standards, and
risks related to semiconductor processing such as the ability to make a
qualified product at commercially acceptable yields.

    OTHER TELECOMMUNICATIONS PRODUCTS.  The technology portfolio for other
telecommunications products includes 1480nm pump lasers which can be used as an
alternative to or in conjunction with 980nm pump lasers for providing optical
power to erbium-doped fiber amplifiers.

    At the date of acquisition, the second generation of these products was in
the wafer growth development stage and was estimated to be released in the
second half of fiscal 1999 and the estimated cost to complete was U.S.$2.3
million from the date of acquisition through fiscal 1999. Uniphase believed the
associated risks of developing this technology into commercially viable products
to be the challenge of meeting the requirements and specifications of the
market, in particular with respect to reliability and customer qualification,
meeting product packaging standards, and risks related to semiconductor
processing such as the ability to make a qualified product at commercially
acceptable yields.

    CABLE TELEVISION ("CATV").  The dominant technologies in this category
include the 1550nm continuous wave ("CW") laser and the 1310nm linearized laser.
Other technologies include return-path lasers and photodiodes.

    At the acquisition date, it was estimated that this portfolio of products
would take 30 months to develop, excluding the research phase of the development
cycle, which is approximately 6 months shorter than the development time for
other products. The first generation of these products had been released and the
second generation was in the wafer growth development stage and was estimated to
be released in the second half of the calendar 1998 with the third generation of
products in the research stage and estimated to be released in fiscal 2002. At
the acquisition date, the estimated costs to complete the technology in this
category was approximately U.S.$3.3 million from the date of acquisition through
fiscal 2002. Uniphase believed the associated risks of developing this
technology into commercially viable products to be the challenge of meeting

                                     S-121

the requirements and specifications of the market, in particular with respect to
reliability and customer qualification, meeting packaging standards, and risks
related to semiconductor processing such as the ability to make a qualified
product at commercially acceptable yields.

    Uniphase Fiber Components

    The primary purchased in-process technology related to fiber Bragg gratings
for wave-length division multiplexing applications. The purchased in-process
technology was comprised of four main categories: (i) temperature compensation,
(ii) unpackaged, (iii) dispersion compensation, and (iv) add-drop/DCM/
circulators.

    The following is a brief description of each acquired IPRD project at the
acquisition date. In each case it is expected that each technology will result
in a product family (portfolio) introduced over many years.

    TEMPERATURE COMPENSATION.  Temperature compensation is a type of packaged
fiber grating where the fiber grating is surrounded by a temperature
compensating package. When heated without this type of package, the properties
of the grating have a propensity to change. However, when the fiber is put in
this package, it is compressed and the temperature effect is compensated so that
grating properties are maintained.

    Uniphase estimated that the development cycle for the first product from
this technology would last 12 months and technological feasibility would be
reached at the end of the beta testing stage. At the acquisition date, the
release date for this product was expected to be in the middle of fiscal 1998
and the estimated cost to complete was U.S.$0.1 million from the date of
acquisition through fiscal 1998. Uniphase believed the associated risks of
developing this technology into commercially viable products to be the challenge
of having the package meet the requirements and specifications of the market.

    UNPACKAGED.  Unpackaged refers to a fiber grating that is not contained in a
"package" or protective encasement. This product is deployed in the
telecommunications industry and in environments where temperature is not a
concern or can be controlled by alternative means other than packaging.

    Uniphase estimated that the development cycle for the first product from
this technology would last 12 months and technological feasibility would be
reached at the end of the beta testing stage. At the date of acquisition, the
release date for this product was expected to be in the first or second quarter
of fiscal 1999 and the estimated cost to complete was U.S.$0.5 million from the
date of acquisition through fiscal 1999. Uniphase believed the associated risks
of developing this technology into commercially viable products to be obtaining
the appropriate filter response and meeting customer/market performance
specifications.

    DISPERSION COMPENSATION.  Dispersion compensation provides a reshaping of an
optical pulse. The pulse "smearing" property as it propagates over long fiber
lengths is called dispersion. The pulse is "smeared out" which leads to errors.
The dispersion compensation technology compensates for the smearing, thus
resolving the errors.

    Uniphase estimated that the development cycle for the first product from
this technology would last 18 months and technological feasibility would be
reached at the end of the beta testing stage. At the date of acquisition, the
release date for this product was expected to be in the first or second quarter
of fiscal 1999 and the estimated cost to complete was U.S.$0.6 million from the
date of acquisition through fiscal 1999. Uniphase believed the associated risks
of developing this technology into commercially viable products to be meeting
customer/market performance specifications.

    ADD-DROP/DCM/CIRCULATORS ("ADD-DROP").  This technology consists of fiber
gratings and other optical components. Specifically, the technology serves as an
optical filter; as light comes in, the filter is able to isolate (drop-off) one
color (wavelength) and let all other colors through. Colors can also be added
back after they pass through. Add-Drop is used for WDM purposes. The technology
is growing very rapidly and, at the time of the acquisition, was just recently
emerging into the marketplace.

    Uniphase estimated that the development cycle for the first product from
this technology would last 18 months and technological feasibility would be
reached at the end of the beta testing stage. At the acquisition date, the
release date for the first version of this product was expected to be in the
first or second quarter of fiscal 1999 and the estimated cost to complete was
U.S.$1.1 million from the date of acquisition through fiscal

                                     S-122

1999. Uniphase believed the associated risks of developing this technology into
commercially viable products to be meeting customer/market performance
specifications.

    Uniphase Laser Enterprises

    The purchased in-process technology related to advanced 980nm semiconductor
lasers. The purchased in-process technology was comprised of three main product
categories: (i) Submount and Ridge Wave Guide ("RWG") Series, (ii) the
distributed feedback laser ("DFB"), and (iii) high power. The development cycle
for all new technologies, on average, takes approximately two years to complete.
The stages of development include: (i) R&D feasibility, (ii) fixing the design,
(iii) engineering performance evaluation, (iv) 5,000 hour life test, and (v)
manufacturing. Technological feasibility is achieved upon successful completion
of the 5,000 hour life test. This stage tests the reliability of the technology
(the most important measure of the end-user).

    The following is a brief description of each acquired IPRD project at the
acquisition date:

    SUBMOUNT AND RIDGE WAVE GUIDE SERIES.  ULE's existing product at the date of
the acquisition was a 150mW pump laser. This project consisted of developing a
family of lasers with power in excess of the existing 150mW lasers (up to
300mW). These lasers are used as pumps in erbium-doped fiberoptic amplifiers and
enable optimized amplifier performance. The lasers are specifically fabricated
to ensure long reliable lifetimes and inherently avoid the failure modes of
other types of 980nm lasers.

    Uniphase estimated that the development cycle for the product family would
last 36 months. At the acquisition date, lasers with power greater than 150mW
were in the engineering performance evaluation stage of the development cycle.
The release date for the first version of this product was expected to be in the
fourth quarter of fiscal 1997 and the estimated cost to complete was U.S.$2.8
million from the acquisition date through fiscal 1998. Uniphase believed the
associated risks of developing this technology into commercially viable products
to be the challenge of meeting the requirements and specifications of the
market, in particular with respect to reliability and customer qualification,
and risks related to semiconductor processing such as the ability to make a
qualified product at commercially acceptable yields.

    DISTRIBUTED FEEDBACK LASER.  These lasers will be used as transmitter
sources for 1550nm communication systems. They rely on a grating formed in the
semiconductor laser structure to distribute the feedback of the laser light,
thereby enhancing the laser-signal fidelity. It was envisioned that these lasers
would be used in optically amplified WDM systems.

    Uniphase estimated that the development cycle for this product family would
last 24 months. At the acquisition date, the DFB was in the R&D feasibility
stage of the development cycle. The release date for the first version of this
product was expected to be in fiscal 1999 and the estimated cost to complete was
U.S.$3.8 million from the acquisition date through fiscal 1999. Uniphase
believed the associated risks of developing this technology into commercially
viable products to be the challenge of meeting the requirements and
specifications of the market, in particular with respect to reliability and
customer qualification, and risks related to semiconductor processing such as
the ability to make a qualified product at commercially acceptable yields.

    HIGH POWER.  The high power project is the development of one to two watt
lasers. These lasers are a fundamentally different design than RWG, in that they
emit light from a broad-area (wide) stripe, require advanced packaging due to
higher heat dissipation requirements, and emit light at different wavelengths.
These lasers will be used for advanced amplifiers.

    Uniphase estimated that the development cycle for this product family would
last 24 months. At the acquisition date, the one to two watt release was in the
engineering performance evaluation stage of the development cycle. The release
date for the first version of this product was expected to be in fiscal 2000 and
the estimated cost to complete was U.S.$2.9 million from the acquisition date
through fiscal 2000. Uniphase believed the associated risks of developing this
technology into commercially viable products to be the challenge of meeting the
requirements and specifications of the market, in particular with respect to
reliability and customer qualification, and risks related to semiconductor
processing such as the ability to make a qualified product at commercially
acceptable yields.

                                     S-123

    Value Assigned to IPRD

    For each acquisition, the value assigned to IPRD was determined by
considering the importance of each project to the overall development plan,
estimating costs to develop the purchased IPRD into commercially viable
products, estimating the resulting net cash flows from the projects when
completed and discounting the net cash flows to their present value. The revenue
estimates used to value the purchased IPRD were based on estimates of relevant
market sizes and growth factors, expected trends in technology and the nature
and expected timing of new product introductions by Uniphase and its
competitors.

    The rates utilized to discount the net cash flows to their present value are
based on Uniphase's weighted average cost of capital and the weighted average
return on assets. Given the nature of the risks associated with the difficulties
and uncertainties in completing each project and thereby achieving technological
feasibility, anticipated market acceptance and penetration, market growth rates,
and risks related to the impact of potential changes in future target markets,
the weighted average cost of capital was adjusted. Based on these factors,
discount rates of 27%, 20%, and 20% were deemed appropriate for UNL, UFC, and
ULE, respectively.

    The estimates used by Uniphase in valuing IPRD were based upon assumptions
Uniphase believes to be reasonable but which are inherently uncertain and
unpredictable. Uniphase's assumptions may be incomplete or inaccurate, and no
assurance can be given that unanticipated events and circumstances will not
occur. Accordingly actual results may vary from the projected results. Any such
variance may have a material adverse effect on the business, financial condition
and results of operations of Uniphase. The value assigned to each acquired IPRD
project at the respective acquisition dates were as follows:



                                                                                                    (IN MILLIONS --U.S.$)
                                                                                                    ---------------------

    Current Status of Acquired IPRD Projects

    Uniphase periodically reviews the stage of completion and likelihood of
success of each of the IPRD projects. The current status of the IPRD projects
for each acquisition are as follows:

    Uniphase Netherlands -- The product introductions for the WDM lasers -- CW
and direct modulation and DFB/BA and modulator are either on schedule or are
approximately 6 months behind schedule. The WDM laser -- direct modulation is
expected to have a lower revenue growth rate than originally anticipated. The
development of the semiconductor optical amplifier technology has been delayed
due to market demand for other products. The development of the telecom
technology is on schedule but the revenue growth rate in initial periods is
expected to be lower than originally anticipated. Development of the CATV
technologies is approximately 6 months behind schedule and is expected to take a
higher level of development effort to bring

                                     S-124

the technology to market. Uniphase has incurred post-acquisition research and
development expenses of approximately U.S.$2.1 million in developing the
acquired in-process technology and estimates that the cost to complete this
technology, in combination with Uniphase's other continuing research and
development expenses, will not be in excess of Uniphase's historic expenditures
for research and development as a percentage of Uniphase's net sales. The
differences between the actual outcome noted above and the assumptions used in
the original valuation of the technology are not expected to ultimately impact
the expected return on investment from the acquisition of UNL or Uniphase's
results of operations and financial position.

    Uniphase Fiber Components -- The initial products developed from submarine
and unpackaged technology projects were completed approximately on schedule and
post-acquisition research and development expenses approximately equaled the
estimated cost to complete at the acquisition date. Uniphase is experiencing
higher levels of demand for the submarine products than anticipated in the
original estimates. The temperature compensation project is behind schedule due
to unforeseen technical difficulties in maintaining specifications at the
harshest environmental test points. The dispersion compensation project is
significantly behind schedule and the market does not appear to be developing as
anticipated. The Add-Drop projects are progressing on schedule. Uniphase has
incurred post-acquisition research and development expenses of approximately
U.S.$2.1 million in developing the acquired in-process technology and estimates
that the cost to complete this technology, in combination with Uniphase's other
continuing research and development expenses, will not be in excess of
Uniphase's historic expenditures for research and development as a percentage of
Uniphase's net sales. The differences between the actual outcome noted above and
the assumptions used in the original valuation of the technology are not
expected to ultimately impact the expected return on investment from the
acquisition of UFC or Uniphase's results of operations and financial position.

    Uniphase Laser Enterprise -- The Submount and RWG series products were
released on schedule and post-acquisition research and development expenses
approximately equaled the estimated cost to complete at the acquisition date.
Actual revenue for these products has significantly exceeded the estimates used
in the valuation of the technology. Uniphase did not pursue development of the
distributed feedback laser due to resources being redirected to expand the
Submount and RWG Series development program in response to strong market demand.
The high power project is somewhat delayed due to shifting R&D resources to
Submount/RWG because of RWG demand. Uniphase has incurred post-acquisition
research and development expenses of approximately U.S.$3.2 million in
developing the acquired in-process technology and estimates that the cost to
complete this technology, in combination with Uniphase's other continuing
research and development expenses, will not be in excess of Uniphase's historic
expenditures for research and development as a percentage of Uniphase's net
sales. The differences between the actual outcome noted above and the
assumptions used in the original valuation of the technology are not expected to
ultimately impact the expected return on investment from the acquisition of ULE
or Uniphase's results of operations and financial position.

    INTEREST AND OTHER INCOME.  Net interest and other income of U.S.$3.3
million for fiscal 1998 represented a decrease of U.S.$179,000 from fiscal 1997
income of U.S.$3.4 million. Fiscal 1997 net interest and other income increased
U.S.$2.0 million over fiscal 1996 income of U.S.$1.4 million. The decrease in
interest and other income in 1998 was primarily due to the reduced level of
short-term investments resulting from the cash payment to IBM of U.S.$45 million
for ULE in March 1997, and the payment to AP of approximately U.S.$6.5 million
for UFC and certain licensing rights in November 1997. In addition, net interest
and other income in fiscal 1998 includes lower interest expense as compared to
fiscal 1997 resulting from the retirement of approximately U.S.$6.1 million in
notes payable in August 1997 originating from the fiscal 1996 acquisition of
UFP. The fiscal 1997 increase over fiscal 1996 was due primarily to the increase
in interest earned on the net proceeds of the public offering of Uniphase Common
Shares in June 1996 and the private placement of Uniphase Common Shares with
KLA-Tencor in November 1995.

    INCOME TAX EXPENSE.  Uniphase recorded tax provisions of U.S.$11.4 million,
U.S.$5.4 million and U.S.$4.0 million for fiscal 1998, 1997 and 1996,
respectively. The effective tax rates for fiscal 1998, 1997 and 1996 were
(137%), (44%) and 56%, respectively, due primarily to IPRD expenses which
provided no immediate tax benefit.

    Uniphase has established a valuation allowance covering a portion of the
gross deferred tax assets originating from its ULE subsidiary acquired in fiscal
1998 and 1997. Approximately U.S.$3 million of the valuation allowance at June
30, 1998 relates to tax benefits of stock option deductions that will be
credited to

                                     S-125

equity when realized. The valuation allowance reduces net deferred tax assets to
amounts considered realizable in the near future based on projected future
taxable income. As there can be no assurance that these European subsidiaries
will generate future taxable income, there can be no assurance that these
valuation allowances will be realized.

LIQUIDITY AND CAPITAL RESOURCES

NINE MONTHS ENDED MARCH 31, 1999 AND 1998

    At March 31, 1999 Uniphase's combined balance of cash, cash equivalents and
short-term investments was U.S.$113.1 million. Uniphase has met its liquidity
needs during fiscal 1999 primarily through cash generated from operating
activities totaling U.S.$40.4 million. Cash provided by operating activities is
primarily the result of net income before depreciation, amortization, asset
write-off and stock compensation expense. Net working capital used U.S.$7.8
million in cash, primarily resulting from an increase in accounts receivable
totaling U.S.$9.9 million.

    Cash used in investing activities was U.S.$62.9 million for the first nine
months of fiscal 1999. Uniphase incurred capital expenditures of U.S.$32.5
million primarily to expand its telecommunications manufacturing capacities, and
for facilities improvement and equipment purchases. Uniphase expects to continue
to expand its worldwide manufacturing capacity, primarily for telecommunication
products by investing approximately U.S.$14 million capital expenditures for the
remainder of fiscal 1999. In addition, Uniphase invested excess net cash of
U.S.$26.7 million in short-term investments during the first nine months of
fiscal 1999.

    During fiscal 1999, Uniphase generated U.S.$13.9 million from the exercise
of stock options and the sale of stock through an employee stock purchase plan.
Cash used for financing activities includes U.S.$648,000 paid to former
shareholders of BCP prior to its acquisition on November 25, 1998.

    In connection with the acquisition of UNL in June 1998, Uniphase may be
obligated to pay additional consideration and interest thereon in the form of
Uniphase Common Shares with a maximum value of 458 million Dutch Guilders
(approximately U.S.$230 million). The number of Uniphase Common Shares to be
issued for the contingent consideration is dependent upon the unit shipments of
certain UNL products during the four-year period ending June 30, 2002 and the
price of Uniphase Common Shares at the time the contingent consideration becomes
probable. The contingent consideration will be recorded at the current fair
value as additional purchase price representing additional goodwill when the
aggregate shipment criteria are met. As of March 31, 1999 Uniphase is not
obligated to recognize any contingent consideration resulting from the UNL
acquisition.

    Uniphase believes that its existing cash balances and short-term
investments, together with cash flow from operations will be sufficient to meet
its liquidity and capital spending requirements at least through the end of
calendar 1999. However, possible acquisitions of businesses, products or
technologies may require additional financing prior to such time. There can be
no assurance that additional financing would be available when required or, if
available, would be on terms satisfactory to Uniphase.

FISCAL YEARS ENDED JUNE 30, 1998, 1997 AND 1996

    Cash provided by operating activities during fiscal 1998 was primarily the
result of net losses of U.S.$19.6 million offset by noncash charges during the
year for depreciation and amortization of U.S.$10.2 million, acquired IPRD costs
of U.S.$40.3 million, stock based compensation of U.S.$6.9 million and the
write-off of certain long-lived assets totaling U.S.$3.6 million. Increases in
accounts receivable of U.S.$12.4 million resulted from higher fourth quarter
sales in fiscal 1998 compared to the prior year and an increase in the number of
days receivable outstanding from 70 days at the end of fiscal 1997 to 83 days in
fiscal 1998. A higher percentage of outstanding receivables in fiscal 1998 were
derived from foreign operations where collection cycles are generally longer
than in the United States. In addition, the fiscal 1998 days sales in accounts
receivable reflects receivables acquired from Philips. Cash flow from operating
activities also benefited from decreases in all other operating assets totaling
U.S.$4.5 million and increases to all other operating liabilities of U.S.$19.4
million.

    Cash used in investing activities was U.S.$38.5 million in fiscal 1998
compared with U.S.$48.9 million and U.S.$83.6 million for fiscal years 1997 and
1996, respectively. Uniphase's acquisitions of UNL and UFC in fiscal 1998
required U.S.$10.8 million in cash. Uniphase incurred capital expenditures of
U.S.$24.3 million primarily for facilities improvements and equipment purchases
to expand its manufacturing capacity primarily for its telecommunications
product lines. Uniphase also purchased intellectual property totaling
U.S.$550,000 for its telecommunications products businesses.

                                     S-126

    Uniphase used U.S.$1.7 million in cash for financing activities in fiscal
1998 as compared to cash provided by financing activities of U.S.$3.8 million in
fiscal 1997. In fiscal 1998, Uniphase generated U.S.$4.9 million from the
exercise of stock options and the sale of stock through its employee stock
purchase plan. Cash used for financing activities included the repayment of
U.S.$6.1 million of notes payable originating from the acquisition of UFP in
fiscal 1996. Uniphase has a U.S.$5.0 million revolving line of credit with a
bank. Advances under the line of credit bear interest at the bank's prime rate
(8.5% at June 30, 1998) and at June 30, 1998 were secured by inventories and
accounts receivable. There were no borrowings under the line as of June 30,
1998. The line of credit was pledged as collateral to secure a letter of credit
issued in connection with the purchase of certain assets of Chassis Engineering,
Inc. in August 1998. (See Note 12 of Notes to the Uniphase Audited Financial
Statements.) Under the terms of the line of credit agreement, Uniphase is
required to maintain certain minimum working capital, net worth, profitability
levels and other financial conditions. The agreement prohibits the payment of
cash dividends and contains certain restrictions on Uniphase's ability to borrow
money or purchase assets or interests in other entities without the prior
written consent of the bank. As of June 30, 1998, Uniphase was in compliance
with all covenants under the agreement.

                                BUSINESS OF JDS

GENERAL

    JDS Optics Inc. was incorporated under the laws of Canada on July 21, 1981
and amalgamated with various inactive holding companies on June 1, 1990 and on
June 30, 1995 to become JDS. On March 26, 1996, JDS completed an initial public
offering of its common shares, becoming a reporting issuer in each of the
provinces of Canada. JDS has no material subsidiaries. It is anticipated that
JDS will amalgamate with one of its wholly-owned subsidiaries, Fitel-Photomatrix
(Canada) Inc., on or about May 31, 1999. The JDS Common Shares are listed for
trading on the TSE under the symbol "JDS". The registered office of JDS is
located at 570 West Hunt Club Road, Nepean, Ontario, K2G 5W8.

    JDS is a Canadian high technology company that provides passive fiberoptic
components and modules, instruments and interconnect (resale) products for the
growing fiberoptic communications market. JDS markets its products worldwide,
with exports from Canada accounting for approximately 97% of its sales in its
fiscal year ended May 31, 1998 and in the nine months ended February 28, 1999.

    JDS has designed and manufactured a broad range of passive fiberoptic
products since 1981. In addition to selling its own components, modules and
instruments, JDS distributes complementary fiberoptic interconnect (resale)
products that are manufactured by third parties. JDS' customers include many of
the world's leading telecommunications service providers, fiberoptic systems
manufacturers and fiberoptics-related research laboratories.

    After a period of strong growth in the 1980s, JDS sought a strategic partner
to increase its access to fiberoptic markets, technologies and applications. In
1990, Furukawa acquired a 50% equity position in JDS and currently has an equity
position of approximately 47.9%. Furukawa, which is listed on the Tokyo Stock
Exchange, is one of Japan's largest producers of fiberoptic cable and
installation equipment. It is also one of the world's leading manufacturers of
electric wire and cable, non-ferrous metal products and other related equipment.
Furukawa had consolidated sales of approximately U.S.$6.1 billion for the fiscal
year ended March 31, 1998 and shareholders' equity of approximately U.S.$1.6
billion as at March 31, 1998.

COMPONENTS AND MODULES

    Components produced by JDS include a variety of product categories. One such
category is couplers, which include WDM, access/bi-directional couplers, optical
isolators and hybrid couplers. JDS manufactures the majority of the passive
components used in a fiber amplifier, including WDM pump combiners, monitor tap
couplers, optical isolators and integrated hybrid couplers. Another category of
component products is optical switches. As more WDM systems are deployed in
telecommunications networks, there are increasing demands for optical switching
technology to provide a higher level of optical functions such as path
protection, dynamic bandwidth provisioning and shared monitoring. JDS' optical
switches are designed to satisfy this demand. Other categories of component
products include attenuators (components typically used in an optical
transmission system to adjust the optical power level to within the dynamic
range of the optical receiver), polarization components such as polarization
combiners (usually used in ultra-high power optical amplifiers to increase the
pump laser power delivered to the active doped fiber) and optical circulators
(generally used in fiber gratings to provide WDM demultiplexing functions) as
well as tunable filters (narrow bandpass filters that are wavelength-tunable by
voltage control).

    JDS has also developed a number of modules, including optical amplifier
modules that are key building blocks in modern transmission networks. An optical
amplifier can boost the optical signal power without conventional electronic
conversion. This permits an optical signal to travel a greater distance between
electronic terminals and regenerators. The result is a simplified network
architecture and a reduction in transmission costs. Optical amplification is
also an enabling technology for dense WDM.

    Other modules produced by JDS include configurable optical add-drop
multiplexer modules (permitting dynamic provisioning of optical bandwidth in
advanced WDM networks), and custom design switching modules or sub-assemblies
(used to provide path protection at the optical layer in WDMs deployed in ring
networks and carrying multiple traffic data types).

INSTRUMENTS

    The products produced by JDS in the instruments products area are used by
research laboratories, system manufacturers and users of telecommunications
equipment to measure the performance of fiberoptic products, and for product
design, manufacturing testing, quality control and environmental testing
purposes. There are three main product categories comprising the instrument
product area, namely, test instruments, controllable attenuators and
programmable switches.

    - TEST INSTRUMENTS.  Test instruments are used for testing and measuring
      optical components. Many of the JDS test instruments were originally
      developed for evaluating JDS' own optical components during the design and
      production phases. An example of a test instrument is the PS series
      polarization meter, which performs high resolution measurement of
      "polarization dependent loss" (an important parameter for optical
      amplifier components used in undersea applications) in real time. This
      allows for dynamic fine-tuning of components during assembly. Other test
      instruments include return loss meters, broadband noise sources and swept
      wavelength test systems (certain of which allow for high speed optical
      spectral analysis of components such as dense WDM demultiplexers).

                                     S-128

    - CONTROLLABLE ATTENUATORS.  Controllable attenuators include products such
      as network attenuators, which are key elements in a dense WDM transmission
      link and are deployed at the optical transmitter, regenerator and receiver
      sites to perform power management functions such as pre-emphasis,
      amplifier gain equalization and optical signal-to-noise ratio adjustments.
      Other products in this category include manually adjustable or
      programmable attenuators for laboratory and automated production testing.

    - PROGRAMMABLE SWITCHES.  Programmable switches include matrix switches,
      which are used mainly in automated test stations for manufacturing or
      reliability testing. They are also key building blocks for network
      elements such as remote fiber testing systems and automatic fiber patch
      panels.

INTERCONNECT (RESALE) PRODUCTS

    JDS has distributed certain products manufactured by either Seikoh Giken or
Furukawa. These products are referred to as interconnect (resale) products and
include fusion splicers, connectors, adaptors, jumpers and cable assemblies and
polishing machines.

    In 1987, JDS became a distributor of Seikoh Giken fiberoptic products for
all markets outside of Japan. JDS formalized this relationship in 1995 with
Seikoh Giken by entering into an agreement, which continues indefinitely unless
terminated by either party on 12 months prior notice. This relationship has
allowed JDS to introduce internationally a number of standard-setting
interconnect products such as polishing machines and accessories. Other
interconnect products manufactured by Seikoh Giken and sold by JDS include high
performance optical connectors, adaptors and cable assemblies.

SALES AND MARKETING

    JDS markets its products through its own sales and marketing personnel and a
network of independent distributors and manufacturers' representatives. The
nature of the fiberoptics industry requires two different types of sales
processes for JDS products. JDS strives to provide timely turnaround for
customers who require products shown in the JDS catalogue. Other customers have
requirements for non-standard or custom products, which often involve new
technology or components. The sales cycle for these products is longer and
requires a greater degree of technical interaction between JDS and customer
personnel.

    All sales are managed by in-house sales and marketing representatives from
JDS' head office located near Ottawa. JDS also has sales and support offices in
France and the United States. In addition, JDS utilizes independent distributors
and manufacturers' representatives located in proximity to major customers.

    JDS has more than 41 independent distributors and manufacturers'
representatives throughout the United States, Europe, Asia, South America, the
Middle East and Australia, who typically also sell a range of fiberoptic
products from various other companies. Approximately 91% of JDS' sales in fiscal
1998 was generated by the combination of its in-house sales personnel and
manufacturers' representatives and the balance through its independent
distributors.

    JDS' in-house sales personnel are trained to address the demands and
requirements of their customers, namely communications engineers and research
personnel. In-house sales personnel, independent distributors and manufacturers'
representatives are provided with proposal support, product management,
application engineering and marketing services. Promotional tools consist of
demonstration systems, brochures, and technical documentation. JDS makes
extensive use of its industry contacts, knowledge of and participation in
international standards bodies, strategic partnering and customer contacts to
identify quality prospects and to manage the sales cycle. JDS also promotes its
products through trade journal advertising, technical conferences and direct
mail.

RESEARCH AND DEVELOPMENT

    JDS' research and development is primarily focussed on market driven product
development, the enhancement of core technologies and the improvement of
operating and manufacturing processes. JDS concentrates its research and
development activities on the products it manufactures. No material amount of
research or development is conducted on JDS' interconnect (resale) products. The
JDS research and development team consists of approximately 430 employees with
extensive backgrounds in all aspects of

                                     S-129

fiberoptics technology. Of these employees, approximately 75 have a Ph.D, 100
have a master's degree in engineering and 255 have an undergraduate university
engineering degree.

    Expenditures on research and development amounted to 7.6% of sales for the
fiscal year ended May 31, 1998, and 8.4% of sales for the nine months ended
February 28, 1999. Research and development efforts are currently focussed on
technology development (including the development of several dense WDM
technologies and optical switching technologies), product development (primarily
market-driven activities to capture medium-term market opportunities) and
process development (aimed at controlling costs and maintaining product quality
and reliability in volume production).

MANUFACTURING

    JDS manufactures the majority of its products (other than interconnect
(resale) products) at its owned 100,000 square foot facilities and at
approximately 246,000 square feet of various leased facilities in Nepean,
Ontario. During fiscal 1998, JDS purchased 54 acres of land in Nepean, Ontario
and began construction of a new 257,000 square foot campus facility to enhance
its research and development capabilities and to expand its manufacturing
facilities. In February, 1999, JDS began occupying the new facility and started
construction of the second phase of the project, which will provide an
additional 212,000 square feet of manufacturing and office space.

    JDS' in-house manufacturing includes those operations that are critical to
achieve quality standards and protect intellectual property. These include
product design, optical assembly, integration and testing of its manufactured
products. The high volume of custom designed products manufactured in-house is
made possible by JDS' proprietary optical assembly stations and cross-trained
staff. Critical manufacturing steps are performed in JDS' clean rooms to ensure
high product reliability.

    Quality assurance is provided through staff training and internal
procedures, which detail operations and responsibilities throughout the
organization, including design, manufacturing and materials handling. Quality
control procedures necessary to meet increasingly stringent customer demands are
in place throughout JDS, including incoming inspection, outgoing testing and
statistical quality control. JDS achieved ISO9002 certification in fiscal 1996
and ISO9001 certification in fiscal 1997 as a means of certifying JDS' quality
management system.

CUSTOMERS

    JDS' customers include many of the leading telecommunications service
providers, fiberoptic system manufacturers and fiberoptics-related research
laboratories. JDS is not dependent on any one customer. In fiscal 1998, three
customers accounted for 13.9%, 13.6% and 12.1%, respectively, of JDS' total
sales. In fiscal 1997, one customer accounted for 11.5% of JDS' total sales. No
individual customer accounted for more than 10% of total sales in more than one
fiscal year.

    During the nine months ended February 28, 1999, four customers accounted for
18.7%, 13.9%, 12.2% and 12.1% of JDS' total sales, respectively.

SOURCES AND AVAILABILITY OF RAW MATERIALS

    JDS' policy is to establish at least two sources of supply for materials
whenever possible. In addition to the following, JDS has certain other sole
source supply arrangements, the loss or interruption of any of which could have
an impact on the ability of JDS to deliver certain products on a timely basis.

    JDS has a sole source supply arrangement for a critical material used in the
manufacture of its products. JDS has a three-year supply agreement dated
February 14, 1996 with such supplier that is automatically renewed beyond the
initial three-year term for 12-month periods unless the agreement is terminated
by either party on six months prior notice. It is JDS' objective to maintain
strategic inventory of the key raw material provided by this supplier. JDS has
enjoyed excellent relations with this supplier.

    In the third quarter of fiscal 1996, JDS incorporated a subsidiary, VitroCom
Inc., to acquire the assets and operations of VitroDynamics Inc. VitroCom Inc.
is located in Mountain Lakes, New Jersey, and manufactures precision glass
components, a key raw material to many JDS manufacturing processes. The
acquisition secured the supply of this critical material to JDS.

                                     S-130

    In the third quarter of fiscal 1997, JDS entered into a contractual joint
venture with Optical Coating Laboratories, Inc. ("OCLI") to capitalize on the
growing opportunities in the dense WDM business. OCLI is one of the world's
largest independent optical thin film coating manufacturers. The contractual
joint venture focuses on accelerating the development and volume supply of high
performance WDM products. Under the terms of the joint venture, OCLI contributes
its expertise to provide optical filters for certain WDM products and addresses
the rapidly evolving need for leading edge applications. Optical filters are one
of the key elements in certain WDM products. The contractual joint venture is
structured as a series of exclusive supply and distribution contracts between
the companies.

COMPETITION

    The market for fiberoptic components includes a large number of competitive
suppliers, many of whom are small or privately owned or whom compete with JDS on
a limited application-specific, geographic, or industry-specific basis. JDS also
competes in certain target markets with competitors that are part of large
industrial groups. Certain of JDS' significant competitors within each product
area are listed below.

    JDS experiences competition in the components and modules product area from
companies such as ADC Telecommunications, AMP Inc., Amphenol Fiber Optic
Products, Corning Incorporated, Corning OCA Corporation, DiCon Fiberoptics Inc.,
E-Tek Dynamics Inc., FDK Corporation, Gould Electronics Inc., Lucent
Technologies, Inc., Photonic Integration Research Inc., Shinkosha K.K., Siecor
Corporation and Sifam Limited. JDS does not believe that any one of these
companies competes in all of the product areas and geographic markets currently
served by JDS.

    The market in which instruments are sold is dominated by many large
multi-national companies, such as Hewlett-Packard Co., Anritsu Wiltron Co., Ando
Corporation and Wavetek Wandel & Goltermann Inc. Other competitors include
Advantest Corporation, EXFO Electro Optical Engineering Inc., Di-Con Fiberoptics
Inc., Rifocs Corporation and Santec Corporation. Market share of the instruments
product area is generally fragmented among a number of large and small
manufacturers. JDS has succeeded in penetrating niche market opportunities for
fiberoptic instruments, often as a result of meeting immediate requirements for
advanced measurement instruments to support demanding test requirements of the
customer's optical components.

    Competition for interconnect (resale) products that are distributed but not
manufactured by JDS is market specific. The fusion splicers industry is
dominated by companies such as Fujikura Ltd., Sumitomo Electric Industries Ltd.,
Furukawa, Siecor Corporation, Siemens A.G. and Ericsson Components AB. JDS
competes against AMP Inc., Siecor Corporation, 3M Company and Alcoa Fujikura
Limited, as well as numerous other smaller companies, in the connectors and
cable assemblies industry. Competitive suppliers of high performance polishing
machines include Seiko Instruments USA Inc. and Buehler Ltd.

INTELLECTUAL PROPERTY

    JDS owns or has rights to certain intellectual property, which includes
inventions, know-how and patents. While policies and procedures are in place to
protect critical intellectual property, JDS believes that its success depends to
a larger extent on the innovative skills, know-how, technical competence and
abilities of its personnel.

    JDS actively monitors and pursues the development and protection of its
intellectual property assets. Management has a policy of pursuing patent
applications diligently. JDS requires its employees and certain of its
customers, suppliers, distributors, agents and consultants to enter into
agreements to further safeguard JDS' intellectual property.

    At May 14, 1999 JDS had approximately 280 patents or patent applications.

EMPLOYEES

    At February 28, 1999, JDS had approximately 3,400 full-time employees and
contract personnel including approximately 430 in research and development, 80
in sales, marketing and service, 2,760 in manufacturing and 130 in general
management and administration. JDS' employees who are employed at locations in
North America are not represented by any collective bargaining organization. JDS
has never experienced a work stoppage, slowdown or strike and considers its
employee relations to be very good.

STOCK OPTION PLANS

DISCONTINUED PLAN

    On November 24, 1994, JDS established a stock option plan (the "Discontinued
Plan") under which the board of directors was entitled to grant options to
purchase JDS Common Shares at the fair market value at the date that the
Discontinued Plan was established to officers and key employees of JDS, provided
that the total number of options did not exceed 10% of the JDS Common Shares. As
at May 31, 1995, no options had been issued pursuant to the Discontinued Plan.

    In the fiscal year ended May 31, 1996, JDS granted options pursuant to the
Discontinued Plan to six employees and directors to purchase up to 553,302
Common Shares at an exercise price of Cdn.$0.82 per share. The options granted
under the Discontinued Plan vest and are exercisable as to 20% on March 21, 1996
and as to the balance in equal amounts on each of the first, second, third and
fourth anniversary dates of the first vesting date. The options granted pursuant
to the Discontinued Plan are non-transferable and each option, unless terminated
pursuant to the Discontinued Plan, expires on March 20, 2003. JDS no longer
issues options pursuant to the Discontinued Plan.

1996 PLAN

    On March 12, 1996, JDS established a stock option plan (the "1996 Plan") for
the benefit of employees (including contract employees) and directors of JDS and
its subsidiaries. On November 5, 1997, the 1996 Plan was amended to permit a
maximum of 10,806,435 JDS Common Shares to be issued under the 1996 Plan.
Subject to the requirements of the 1996 Plan, the compensation committee of the
JDS Board of Directors or in lieu thereof, the JDS Board of Directors, has the
authority to select those directors and employees to whom options will be
granted as well as the number of options to be granted to each director and
employee and the periods during which the options vest. Options granted pursuant
to the 1996 Plan are non-transferable and each option, unless terminated
pursuant to the 1996 Plan, expires on a date determined by the compensation
committee, which date will not be later than 10 years from the date that the
option was granted.

    As at May 14, 1999, JDS had available a total of 5,696,653 Common Shares to
be granted under the 1996 Plan. In fiscal 1998, JDS granted at total of
1,232,655 options pursuant to the 1996 Plan at exercise prices ranging from
Cdn.$10.88 to Cdn.$28.50.

COMPENSATION COMMITTEE

    During the fiscal year ended May 31, 1998, the JDS Board of Directors and
the compensation committee reviewed the compensation paid to senior executives
of JDS. The compensation committee consists of:

    Koichi Abe

    Bruce D. Day

    Robert E. Enos

    William J. Sinclair.

REPORT ON EXECUTIVE COMPENSATION

    All employees of JDS receive compensation based on the type of job they
perform, the level of responsibility, internal pay equity and their level of
individual performance. The pay for performance philosophy adopted by the JDS
Board of Directors and the compensation committee specifically emphasizes the
payment of competitive salaries, the payment of bonuses for exceeding
objectives, and the granting of a sufficient number of stock options to motivate
the executives and all other employees of JDS to continue the growth of JDS in a
highly competitive business environment.

    An executive compensation package may consist of up to three components: a
base salary, an incentive component and stock options. The overall program is
designed to attract, retain and reward superior individuals, who will ensure the
long-term success of JDS. Enhancing long-term shareholder value is a paramount
objective for JDS and all of its executives. Establishing an appropriate level
of short and long term incentives is essential to the continued success of JDS.

    JDS seeks to pay its employees salaries that are competitive with other high
technology companies. JDS reviews compensation packages annually based on market
data from peer group and industry survey sources. Salaries are determined on the
basis of outside market data as well as an individual's past and anticipated
future performance, level of responsibility and contribution to business
performance. Bonuses are awarded to individuals who exceed management's
objectives in the fiscal year. Stock options are designed to provide a long term
incentive and to permit the employees and directors of JDS and its subsidiaries
to participate in the growth and success of JDS.

    In fiscal 1998, the compensation of the President and Chief Executive
Officer was recommended by the compensation committee and reviewed and approved
by the JDS Board of Directors subject to the employment agreement between JDS
and its Chief Executive Officer. The compensation for all other senior
executives was recommended by the President and Chief Executive Officer and
reviewed and approved by the compensation committee subject to any relevant
employment agreements between JDS and such senior executives.

COMPENSATION OF DIRECTORS

    In fiscal 1998, JDS paid to every director who was not also an employee or
consultant of JDS or Furukawa out of pocket expenses plus directors' fees of
Cdn.$5,000 per annum, Cdn.$500 for each board of directors meeting or committee
meeting attended and, if the director was a chairman of a committee of the JDS
Board of Directors, an additional fee of Cdn.$500 for each meeting of such
committee chaired. In fiscal 1998, the past chairman of the JDS Board of
Directors, Mr. Shuzo Mihara, in such capacity, was paid out of pocket expenses
plus director's fees of Cdn.$15,000 per annum, Cdn.$1,250 for each JDS Board of
Directors meeting attended and a fee of Cdn.$500 for each committee meeting
attended. Pursuant to the 1996 Plan, directors are eligible for options as
declared by the JDS Board of Directors. Aggregate fees in the amount of
Cdn.$73,250 were paid by JDS to such directors as a group in respect of fiscal
1998. In addition to options granted to executive officers that are also
directors disclosed elsewhere herein, options to purchase up to 22,500 Common
Shares with an exercise price of Cdn.$10.88 per share were granted to one other
director in respect of fiscal 1998.

DIRECTORS' AND OFFICERS' LIABILITY INSURANCE

    The JDS By-Laws provide that JDS is required to indemnify a director or
officer of JDS against liability incurred in such capacity to the extent
permitted or required by the CBCA. JDS maintains directors' and officers'
liability insurance, insuring directors and officers of JDS against liability
for acts or omissions in their capacities as directors or officers, subject to
certain exclusions. The maximum amount payable under the policy is
Cdn.$20,000,000 per occurrence and Cdn.$20,000,000 per year, subject to a
deductible of Cdn.$50,000 per occurrence. The annual premium payable to maintain
such insurance is Cdn.$45,000.

                                     S-136

OPTIONS OUTSTANDING

    As at May 14, 1999, options to purchase the following JDS Common Shares were
outstanding:

    (i) 1,859,160 JDS Common Shares, granted to the executive officers of JDS;

    (ii) 300,749 JDS Common Shares, granted to the directors of JDS (other than
         executive officers); and

   (iii) 2,140,938 JDS Common Shares, granted to other employees of JDS.

    Such options were granted between March 21, 1996 and May 14, 1999 with
various expiry dates to May, 2006. The exercise prices of such options range
from Cdn.$0.82 to Cdn.$92.00.

LEGAL PROCEEDINGS

    With the exception of a proceeding before the Ontario Labour Relations Board
discussed in the next paragraph, JDS is not aware of any pending material legal
proceedings to which it is a party or to which any of its properties are
subject.

    On July 13, 1998, the Christian Labour Association of Canada ("CLAC"), filed
an unfair labour practice complaint under the LABOUR RELATIONS ACT (Ontario)
(the "OLRA"). CLAC alleged that JDS and certain of its managers sought to
interfere with CLAC's union organizing drive contrary to the OLRA. Hearings
before the Ontario Labour Relations Board were completed on November 16, 1998.
No decision has yet been delivered; however, JDS does not believe that the OLRA
proceeding, if determined adversely to JDS, will have a material adverse effect
on the business, financial condition or results of operations of JDS or JDS
Uniphase.

INTERESTS OF INSIDERS IN PRIOR TRANSACTIONS

    On May 29, 1998, in exchange for Furukawa's 68% controlling interest in
FITEL-Photomatrix (Canada) Inc. ("Photomatrix"), JDS issued 743,420 JDS Common
Shares to Furukawa.

    On September 3, 1998, JDS acquired the remaining 32% equity interest in
Photomatrix for Cdn.$12.6 million in cash and 43,475 JDS Common Shares. Each of
Philip Garel-Jones (Vice-President of JDS), Gary Duck, William J. Sinclair and
Jozef Straus had a direct or indirect 3% equity interest in Photomatrix worth
Cdn.$1,035,000 each. Each of F. David King and Yves Tremblay, who are currently
insiders of JDS, had an indirect 10% equity interest in Photomatrix worth
Cdn.$4,721,981 each. As partial consideration for Mr. Tremblay's indirect
interest, JDS issued to Mr. Tremblay 43,475 JDS Common Shares.

    The JDS Board of Directors delegated its authority to review and approve the
above transactions to a special committee comprised of independent members of
the Board (the "Committee"). Based on a fairness opinion, the Committee
concluded that the acquisition of Photomatrix in its entirety was fair, from a
financial point of view, to the minority shareholders of JDS.

SHARE CAPITAL OF JDS

    The following summary of certain provisions of JDS' share capital describes
all material provisions of, but does not purport to be complete and is subject
to, and qualified in its entirety by, the JDS Articles, the JDS By-Laws and by
the provisions of applicable law.

COMMON SHARES

    As of May 14, 1999, there were an unlimited number of JDS Common Shares
authorized, of which 78,411,178 were outstanding. The holders of JDS Common
Shares are entitled to receive notice of and to attend all meetings of the JDS
Shareholders and are entitled to one vote for each share held of record on all
matters submitted to a vote of holders of JDS Common Shares. Subject to the
prior rights of the holders of any shares ranking senior to the JDS Common
Shares with respect to priority in the payment of dividends, the holders of JDS
Common Shares are entitled to receive such dividends as may be declared by the
JDS Board of Directors out of funds legally available therefor. Holders of JDS
Common Shares are entitled upon any liquidation, dissolution or winding-up of
JDS, subject to the prior rights of the holders of any shares ranking senior to
the JDS Common Shares, to receive the remaining property and assets of JDS.

                                     S-137

PREFERRED SHARES

    The JDS Preferred Shares, an unlimited number of which are authorized and
none of which are outstanding, are issuable in series. The JDS Board of
Directors has the power to fix the number of shares in and the designation and
attributes of each series. The JDS Preferred Shares of each series, with respect
to the payment of dividends and the distribution of assets in the event of the
liquidation, dissolution or winding-up of JDS, whether voluntary or involuntary,
or any other distribution of the assets of JDS among its shareholders for the
purpose of winding up its affairs, rank on a parity with every other series of
JDS Preferred Shares and are entitled to preference over the JDS Common Shares
and the shares of any other class ranking junior to the JDS Preferred Shares.
The JDS Preferred Shares of any series are also entitled to any other
preferences, not inconsistent with the provisions set out in the JDS Articles,
over the JDS Common Shares and the shares of any other class ranking junior to
the JDS Preferred Shares.

SECURITY OWNERSHIP

    Furukawa is the beneficial owner of 37,359,670 JDS Common Shares comprising
approximately 47.6% of the issued and outstanding shares and exercises direction
over an additional 3,130,000 JDS Common Shares for the purpose of voting on the
JDS Arrangement Resolution at the JDS Meeting. See "The Transaction -- Furukawa
Support Agreement" and "The Transaction -- Shareholder Approval and the Special
Meetings". To the knowledge of JDS, no other person is the beneficial owner of,
or exercises control or direction over, more than 5% of the JDS Common Shares.
However, since beneficial ownership of less than 10% of the JDS Common Shares is
not required to be disclosed under Canadian securities laws, it is difficult to
identify beneficial holders of less than 10% of the issued and outstanding JDS
Common Shares. See "The Companies after the Transaction -- Directors and
Officers" for pro forma ownership of Uniphase Common Shares after completion of
the Transaction.

    At May 14, 1999, the directors and officers of JDS beneficially owned,
directly or indirectly, or exercised control or direction over approximately
3.0% of the total number of issued and outstanding JDS Common Shares.
Information as to shares owned indirectly or over which control or direction is
exercised by the directors and senior officers, but which are not registered in
their names, not being within the knowledge of JDS, has been furnished by those
directors and senior officers.

                  JDS MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

    JDS designs, manufactures, distributes and supports a wide range of
fiberoptic components and modules, instruments, and interconnect (resale)
products which address the growing fiberoptic communications market. JDS' growth
continues to be driven by the on-going demand for transmission capacity and the
impact of global deregulation on the telecommunication industry. More
specifically, growth for fiscal 1998 can be attributed, in part, to the large
scale deployment of WDM, the need for more functionality at the optical layer
and JDS' ability to capitalize on its manufacturing and engineering strengths to
accommodate increasing demand and growing volumes.

    Sales for fiscal 1998 were Cdn.$227.2 million, an increase of 97.6% over
fiscal 1997. Net income for fiscal 1998 was Cdn.$47.6 million compared with
Cdn.$22.5 million achieved in fiscal 1997, an increase of 112.1%.

    In fiscal 1998, JDS undertook a number of corporate initiatives including a
Cdn.$118.2 million common share offering to fund acquisition, capital asset
purchase and working capital requirements to support anticipated future growth.
JDS also purchased 54 acres of land and began construction on a new 257,000
square foot campus facility to enhance its research and development and
manufacturing facilities. In addition, JDS issued 743,420 JDS Common Shares to
acquire a 68% equity interest in FITEL-Photomatrix (Canada) Inc. Finally, JDS
Common Shares were split on a three-for-one basis to provide access to a wider
range of investors.

    The growth in sales in components and modules and in the instruments product
groups in all periods presented continues to be driven by increasing global
demand for transmission capacity which fueled strong demand for optical
networking products. JDS was successful in working with its customer base, which
includes telecommunication service providers and fiberoptic systems
manufacturers, to provide products to satisfy this demand. In particular, the
strong growth for WDM, power management and switching applications have been
major contributors to JDS' revenue growth.

    JDS sells its products worldwide. JDS markets its products through its own
sales and marketing personnel, as well as through a network of independent
distributors and manufacturers' representatives. JDS' sales territories are
divided into five main regions: the United States, Europe, Asia Pacific, Canada
and Other. The following table sets forth sales to each geographic region for
the fiscal years as indicated:

* Based on invoicing address

    The United States continues to be the primary market for JDS products, with
sales in this region accounting for 79% of total sales in the nine months ended
February 28, 1999 compared to 73% in the nine months ended February 28, 1998.
The sales growth in the United States was driven by continued demand for
bandwidth capacity.

    GROSS PROFIT MARGIN

    The gross profit margin for the nine months ended February 28, 1999 was
52.2% compared with 52.0% achieved in the same period ended February 28, 1998.
The overall margin in any given period is impacted by the sales mix among and
within JDS' three product areas, as well as product pricing, new product
introduction, operational efficiencies and U.S. dollar exchange fluctuations
resulting from the majority of JDS' sales being transacted in U.S. dollars.

    The increase in selling, general and administrative expenses is primarily
attributable to the growth in staffing levels, related compensation costs,
facilities expansion and commissions on sales generated by JDS' manufacturers'
representatives. These changes were required to support JDS' revenue growth.

    JDS concentrates its research and development activities on the products it
manufactures. No material amount of research or development is conducted on
interconnect (resale) products. The growth in research and development was
predominantly the result of increases in technical staffing levels and other
project costs associated with the development of JDS' product lines to meet
various current and future market requirements. JDS earns investment tax credits
("ITC's") at a rate of 20.0% of qualified expenses. The amounts shown as
research and development in the JDS Unaudited Financial Statements are net of
ITC's. Research costs are expensed as incurred. Development costs are expensed
as incurred unless they meet generally accepted accounting criteria for
deferral. To date, no development costs have been deferred.

    INVESTMENT AND OTHER INCOME

    During the nine months ended February 28, 1999, JDS earned investment income
of Cdn.$6.5 million compared to Cdn.$3.2 million in the same period of fiscal
1998. This increase is primarily due to interest earned on the Cdn.$118.2
million of cash proceeds from the JDS Common Share offering completed in
November of 1997. JDS invests its excess cash balances in low risk short-term
money market products issued by the Government of Canada and large, recognized
Canadian financial institutions.

    INCOME TAXES

    The effective tax rate for the nine month periods ended February 28, 1999
and 1998 was 37.0%. The effective tax rate is lower than the statutory rate
primarily as a result of certain deductions related to manufacturing and
processing activities and research and development expenditures.

Increase over prior period........................................................................      93.1%     139.0%


    The increases in net income in the periods indicated resulted from increases
in sales and gross profit, an increase in investment income, which was offset by
increases in operating expenses and income taxes.

    Under Canadian GAAP, gains and losses on foreign exchange contracts related
to anticipatory transactions, without a firm commitment, are not recognized
until realized. Under U.S. GAAP, gains and losses on such foreign exchange
contracts are recognized in the period that the exchange rates change.
Accordingly, net income for the nine months ended February 28, 1999 would be
Cdn.$2.3 million higher (1998 -- Cdn.$1.0 million higher) under U.S. GAAP due to
the recognition of unrealized gains and losses on foreign exchange contracts.
Basic and diluted earnings per share under U.S. GAAP would be Cdn.$0.87 and
Cdn.$0.84, respectively.

    FOREIGN CURRENCY EXCHANGE

    JDS sells its products worldwide, primarily in U.S. dollars. As well, a
significant portion of its interconnect (resale) products are purchased in
Japanese yen. JDS incurs some expenditures in U.S. dollars, which creates a
partial natural foreign currency hedge. JDS also purchases foreign exchange
contracts to hedge a portion of its future foreign cash flows. JDS does not
engage in speculative foreign exchange trading activities.

    As at February 28, 1999 JDS had forward exchange contracts in place to
exchange U.S. dollars for Canadian dollars in an aggregate amount of U.S.$40.5
million at forward rates between 1.4078 and 1.5476. JDS also had forward
exchange contracts in place to exchange U.S. dollars for Japanese yen in an
aggregate amount of U.S.$4.0 million at forward rates between 111.50 and 137.18.

FINANCIAL POSITION

    LIQUIDITY AND CAPITAL RESOURCES

    As at February 28, 1999, the working capital balance was Cdn.$194.4 million,
a decrease from Cdn.$204.5 million at May 31, 1998. As at February 28, 1999,
JDS' combined balance of cash, cash equivalents and short-term investments was
Cdn.$143.2 million, a decrease of Cdn.$43.2 million from May 31, 1998. The
decrease is primarily due to the purchase of the assets of Akzo Nobel's
Photonics Business Unit for Cdn.$19.0 million, the purchase of the remaining 32%
equity interest in FITEL-Photomatrix (Canada) Inc. for Cdn.$12.6 million, as
well as Cdn.$62.2 million of capital assets including Cdn.$27.1 million for
facilities expansion. These investments were offset by Cdn.$43.3 million
generated from operations.

    Since May 31, 1998, cash and cash equivalents decreased Cdn.$21.8 million.
In addition to the activities mentioned above, net proceeds from investments
contributed Cdn.$21.5 million and financing activities contributed Cdn.$3.8
million.

    There was no long-term debt outstanding in any of the periods covered in
this discussion.

    Shareholders' equity increased by Cdn.$69.7 million in the nine months ended
February 28, 1999. This increase is primarily attributable to an increase in net
income.

    JDS has short-term bank credit facilities of approximately Cdn.$65.0
million. As at February 28, 1999, there were no outstanding borrowings under
these facilities.

    JDS believes that a combination of JDS' existing cash, cash equivalents,
short-term investment balances, bank credit facilities and cash generated from
operations will be sufficient to meet its operating and capital expenditure
requirements in the near-term.

    Under Canadian GAAP, gains and losses on foreign exchange contracts related
to anticipatory transactions, without a firm commitment, are not recognized
until realized. Under U.S. GAAP, gains and losses on such foreign exchange
contracts are recognized in the period that the exchange rates change.
Accordingly, accounts payable at February 28, 1999 would be Cdn.$3.6 million
lower (1997 -- Cdn.$1.5 million lower) and income taxes payable would be
Cdn.$1.3 million higher (1997 -- Cdn.$0.5 million higher) under U.S. GAAP due to
the recognition of unrealized gains and losses on foreign exchange contracts.

    The growth in sales in all product groups and in each fiscal year presented
continues to be driven by increasing global demand for transmission capacity
which fueled strong demand for optical networking products. JDS was successful
in working with its customer base, including telecommunication service providers
and fiberoptic systems manufacturers, to provide products to satisfy this
demand. In particular, the strong growth for WDM, power management and switching
applications have been major contributors to JDS' revenue growth.

    JDS sells its products worldwide. JDS markets its products through its own
sales and marketing personnel as well as through a network of independent
distributors and manufacturers' representatives. JDS' sales

                                     S-143

territories are divided into five main regions: the United States, Europe, Asia

*   Based on invoicing address

    The United States continues to be the primary market for JDS products, with
sales in this region increasing to 74% of total sales in fiscal 1998 compared to
71% in fiscal 1997 and 68% in fiscal 1996. The sales growth in the United States
was driven by continued demand for bandwidth capacity.

    GROSS PROFIT MARGIN

    The gross profit margin for fiscal 1998 was 52.0% compared with 53.3% in
fiscal 1997 and 53.0% in fiscal 1996. The overall margin in any given period is
impacted by the sales mix among and within JDS' three product areas, product
pricing, new product introduction, operational efficiencies and U.S. dollar
exchange fluctuations resulting from the majority of JDS' sales being transacted
in U.S. dollars. During the last five years, JDS' gross margin has ranged from
52.0% to 55.2%.

Increase over prior year...........................................................       56.4%      57.0%      31.2%


    The increase in selling, general and administrative expenses ("SG&A") is
primarily attributable to the growth in staffing levels, related compensation
costs, facilities expansion and commissions on sales generated by JDS'
manufacturers' representatives. These changes were required to support JDS'
revenue growth. SG&A expenditures in fiscal 1998 were at the low end of the five
year range of 13.4% to 17.0% of sales, since much of the growth occurred late in
the year.

                                     S-144

    JDS' research and development is primarily focussed on market driven product
development, the enhancement of core technologies and the improvement of
operating and manufacturing processes. JDS concentrates its research and
development activities on products it manufactures. No material amount of
research or development is conducted on interconnect (resale) products. The
growth in R&D was predominantly the result of increases in technical staffing
levels and other project costs associated with the development of JDS product
lines to meet various current and future market requirements.

    JDS earns ITCs at a rate of 20.0% of qualified expenses. The amounts shown
as research and development in the JDS Audited Financial Statements are net of
ITCs. Research costs are expensed as incurred. Development costs are expensed as
incurred unless they meet generally accepted accounting criteria for deferral.
To date, development costs have not been deferred. During the last five years,
JDS' gross research and development expenses as a percentage of manufactured
product sales have ranged from 5.9% to 10.0%.

    INVESTMENT AND OTHER INCOME

    During fiscal 1998, JDS earned investment income of Cdn.$5.3 million
compared to Cdn.$1.5 million in fiscal 1997 and Cdn.$0.5 million in fiscal 1996.
This increase is primarily due to interest earned on the Cdn.$118.2 million of
cash proceeds from the JDS Common Share offering completed in November 1997. JDS
invests its excess cash balances in low risk short-term money market products
issued by the Government of Canada and large, recognized Canadian financial
institutions.

    PROFIT SHARE ALLOCATION

    As a private company, JDS paid out a substantial amount of its income in the
form of bonuses, management fees and dividends. The amount of such bonuses and
management fees have been classified as profit share allocation in the JDS
Audited Financial Statements. Since the practice of making such payments was
discontinued when JDS became a public company, management believes that an
adjustment to historical income to account for such payments should be made to
arrive at a normalized amount of income. This normalized income, net of a
provision for income taxes, is presented under the heading "Selected Historical
Financial Data -- Selected Historical Financial Data of JDS" as adjusted net
income. There was no profit share allocation in fiscal 1997 or 1998.

    INCOME TAXES

    The effective tax rate for JDS for fiscal 1998 was 37.0% compared with 37.1%
in fiscal 1997 and 36.4% in fiscal 1996. The effective tax rate is lower than
the statutory rate primarily as a result of certain deductions related to
manufacturing and processing activities and research and development
expenditures. During the last five years, JDS' income tax expense has ranged
from 36.0% to 37.1% of income before income taxes.

                              ADJUSTED NET INCOME



                                                                                        FISCAL YEAR ENDED MAY 31,
                                                                                     -------------------------------
                                                                                       1998       1997       1996
                                                                                     ---------  ---------  ---------
                                                                                     (Canadian dollars in thousands)
                                                                                                  
Adjusted net income................................................................  $  47,635  $  22,459  $  14,903
As a percentage of sales...........................................................       21.0%      19.5%      19.9%
Increase over prior year...........................................................      112.1%      50.7%      10.9%


    The increases in net income for fiscal 1998, 1997 and 1996 resulted from
increases in sales and gross profit, offset by increases in operating expenses
and income taxes. During the last five years, JDS' adjusted net income has
ranged from 19.5% to 23.5% of sales.

    Under Canadian GAAP, gains and losses on foreign exchange contracts related
to anticipatory transactions, without a firm commitment, are not recognized
until realized. Under U.S. GAAP, gains and losses on such foreign exchange
contracts are recognized in the period that the exchange rates change.
Accordingly, net income for the year ended May 31, 1998 would be Cdn.$2.1
million lower (1997 -- Cdn.$0.2 million lower) under

                                     S-145

U.S. GAAP due to the recognition of unrealized gains and losses on foreign
exchange contracts. Basic and diluted earnings per share under U.S. GAAP would
be Cdn.$0.61 and Cdn.$0.59, respectively.

    FOREIGN CURRENCY EXCHANGE

    JDS sells its products worldwide, primarily in U.S. dollars. As well, a
significant portion of its interconnect (resale) products are purchased in
Japanese yen. JDS incurs some expenditures in U.S. dollars which creates a
partial natural foreign currency hedge. JDS also purchases foreign exchange
contracts to hedge a portion of its future foreign cash flows. JDS does not
engage in speculative foreign exchange trading activities.

    At May 31, 1998, JDS had forward exchange contracts in place to exchange
U.S. dollars for Canadian dollars in an aggregate amount of U.S.$43.7 million at
forward rates between 1.3690 and 1.4486. At May 31, 1998, JDS also had forward
exchange contracts in place to exchange U.S. dollars for Japanese yen in an
aggregate amount of U.S.$6.0 million at forward rates between 116.11 and 131.96.

FINANCIAL POSITION

    LIQUIDITY AND CAPITAL RESOURCES

    During fiscal 1998, working capital balances increased from Cdn.$72.0
million to Cdn.$204.5 million. As at May 31, 1998, JDS' combined balance of
cash, cash equivalents and short-term investments was Cdn.$186.5 million, an
increase of Cdn.$130.4 million from May 31, 1997. The increase is primarily
attributable to the offering of JDS Common Shares of Cdn.$118.2 million.
Operating cash flow of Cdn.$49.0 million was primarily utilized to fund
Cdn.$36.8 million of capital assets including Cdn.$14.9 million for facilities
expansion.

    Cash provided by operations increased to Cdn.$49.0 million in fiscal 1998
compared to Cdn.$21.8 million for fiscal 1997. This increase was primarily
attributable to an increase in net income offset by an increase in non-cash
working capital balances resulting from the 97.6% increase in sales.

    Cash used in investing activities increased from Cdn.$13.7 million in fiscal
1997 to Cdn.$196.9 million in fiscal 1998. This increase was primarily
attributable to the increase in short-term investments of Cdn.$153.3 million as
well as a Cdn.$14.2 million increase in capital asset purchases and the
Cdn.$14.9 million disbursed to date for the purchase of land and construction of
a new facility.

    There was no long-term debt outstanding at the end of fiscal 1998 or fiscal
1997.

    Shareholders' equity increased by Cdn.$171.1 million from fiscal 1997 to
Cdn.$267.1 million at the end of fiscal 1998. This increase is primarily
attributable to the offering of JDS Common Shares and net income earned in the
year.

    JDS has short-term bank credit facilities of approximately Cdn.$65.0
million. At May 31, 1998, there were no outstanding borrowings under these
facilities.

    JDS believes that a combination of JDS' existing cash, cash equivalents,
short-term investment balances, bank credit facilities and cash generated from
operations will be sufficient to meet its operating expenditure requirements in
the near-term.

    Under Canadian GAAP, gains and losses on foreign exchange contracts related
to anticipatory transactions, without a firm commitment, are not recognized
until realized. Under U.S. GAAP, gains and losses on such foreign exchange
contracts are recognized in the period that the exchange rates change.
Accordingly, accounts payable at May 31, 1998 would be Cdn.$3.2 million higher
(1997 -- Cdn.$0.4 million higher) and income taxes payable would be Cdn.$1.2
million lower (1997 -- Cdn.$0.1 million lower) under U.S. GAAP due to the
recognition of unrealized gains and losses on foreign exchange contracts.

FORWARD-LOOKING STATEMENTS

    The discussion and analysis of JDS financial results for the nine months
ended February 28, 1999 with the previous period and for fiscal 1998 compared
with the previous two years is intended to assist shareholders and other readers
in understanding JDS' business and the key factors underlying its financial
results. Certain statements in this management's discussion and analysis
constitute forward-looking statements. Such forward-

                                     S-146

looking statements involve known and unknown risks, uncertainties and other
factors which may cause the actual results and performance of JDS and the
industry to be materially different from any future results and performance
expressed or implied by such forward-looking statements. Such factors include,
among others, general economic and business conditions, timing of new product
introductions, industry competition, industry capacity and the ability of JDS to
attract and retain key employees.

                    TAX CONSIDERATIONS FOR JDS SHAREHOLDERS

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS FOR JDS SHAREHOLDERS

    In the opinion of Osler, Hoskin & Harcourt, Canadian counsel for JDS, the
following is a summary of the principal Canadian federal income tax
considerations under the Canadian Tax Act generally applicable to JDS
Shareholders who, for purposes of the Canadian Tax Act, hold their JDS Common
Shares, and will hold their Exchangeable Shares and/or Uniphase Common Shares,
as capital property and deal at arm's length with JDS, Uniphase, Uniphase Nova
Scotia and Exchangeco. This summary does not apply to a Shareholder with respect
to whom Uniphase is or will be a foreign affiliate within the meaning of the
Canadian Tax Act. This summary also does not apply to JDS Shareholders who
indirectly own their JDS Common Shares through a Holding Company and who elect
to exercise the Holding Company Alternative. Such JDS Shareholders should
consult their own tax advisors as to the tax consequences to them of
participating in the Holding Company Alternative.

    JDS Common Shares, Exchangeable Shares and Uniphase Common Shares will
generally be considered to be capital property to a shareholder unless any such
shares are held in the course of carrying on a business of buying and selling
shares or such shares are acquired in a transaction considered to be an
adventure in the nature of trade. Canadian Resident shareholders whose JDS
Common Shares or Exchangeable Shares might not otherwise qualify as capital
property may be entitled to obtain such qualification by making the irrevocable
election provided by subsection 39(4) of the Canadian Tax Act. JDS Shareholders
who do not hold their JDS Common Shares as capital property should consult their
own tax advisors regarding their particular circumstances. In addition, the
mark-to-market rules contained in the Canadian Tax Act relating to financial
institutions (including certain financial institutions, registered securities
dealers and corporations controlled by one or more of the foregoing) will
generally deem such financial institutions not to hold their JDS Common Shares,
Exchangeable Shares or Uniphase Common Shares as capital property for the
purposes of the Tax Act. JDS SHAREHOLDERS THAT ARE FINANCIAL INSTITUTIONS SHOULD
CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE TAX CONSEQUENCES TO THEM OF THE
APPLICATION OF THE MARK-TO-MARKET RULES.

    This summary is based on the current provisions of the Canadian Tax Act, the
regulations thereunder and counsel's understanding of the current administrative
practices published by Revenue Canada, all in effect as of the date of this
Supplement. This summary takes into account all Tax Proposals, although no
assurance can be given that the Tax Proposals will be enacted in the form
presented, or at all. This summary does not take into account or anticipate any
other changes in law, whether by judicial, governmental or legislative action or
decision, nor does it take into account provincial, territorial or foreign
income tax legislation or considerations, which may differ from the Canadian
federal income tax considerations described herein. No advance income tax ruling
has been sought or obtained from Revenue Canada to confirm the tax consequences
of any of the transactions described herein.

    THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, AND
SHOULD NOT BE CONSTRUED TO BE, LEGAL, BUSINESS OR TAX ADVICE TO ANY PARTICULAR
SHAREHOLDER. SHAREHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE TAX
CONSEQUENCES OF THE DESCRIBED TRANSACTIONS IN THEIR PARTICULAR CIRCUMSTANCES.

    For the purposes of the Canadian Tax Act, all amounts relating to the
acquisition, holding or disposition of Uniphase Common Shares must be expressed
in Canadian dollars, including dividends, adjusted cost base and proceeds of
disposition; amounts denominated in United States dollars must be converted into
Canadian dollars based on the prevailing United States dollar exchange rate
generally at the time such amounts arise.

                                     S-147

JDS SHAREHOLDERS RESIDENT IN CANADA

    The following portion of the summary is applicable to a JDS Shareholder who,
for the purposes of the Canadian Tax Act and any relevant bilateral tax treaty,
and at all relevant times, is resident or deemed to be resident in Canada while
holding JDS Common Shares, Exchangeable Shares or Uniphase Common Shares.

    AMALGAMATION

    On the Amalgamation, a JDS Shareholder will be deemed to have disposed of
the JDS Common Shares owned by the JDS Shareholder for proceeds of disposition
equal to the adjusted cost base to the JDS Shareholder of those shares
immediately before the Amalgamation; as a result, no capital gain or capital
loss will generally arise for a JDS Shareholder on the Amalgamation. The JDS
Shareholder will be deemed to have acquired Class B Non-Voting Preference Shares
received on the Amalgamation at a cost equal to the proceeds of disposition of
the JDS Common Shares owned by the JDS Shareholder.

    EXCHANGE OF CLASS B NON-VOTING PREFERENCE SHARES FOR UNIPHASE COMMON SHARES

    A JDS Shareholder who exchanges Class B Non-Voting Preference Shares for
Uniphase Common Shares (including any related Uniphase Rights) will be
considered to have disposed of such Class B Non-Voting Preference Shares for
proceeds of disposition equal to the sum of (i) the fair market value of the
Uniphase Common Shares (including any related Uniphase Rights) acquired by such
JDS Shareholder on the exchange and (ii) any cash received by such holder in
respect of a fractional Uniphase Common Share. The JDS Shareholder will realize
a capital gain (or capital loss) equal to the amount by which the proceeds of
disposition of such Class B Non-Voting Preference Shares, net of any reasonable
costs of disposition, exceed (or are less than) the adjusted cost base to the
JDS Shareholder of such Class B Non-Voting Preference Shares. The general tax
treatment of gains and losses is discussed below under the heading "Taxation of
Capital Gain or Capital Loss". The cost to a JDS Shareholder of Uniphase Common
Shares acquired on the exchange will be equal to the fair market value of such
Uniphase Common Shares at the time of the exchange, to be averaged with the
adjusted cost base of any other Uniphase Common Shares held by the JDS
Shareholder as capital property for the purposes of determining the holder's
adjusted cost base of such Uniphase Common shares.

    EXCHANGE OF CLASS B NON-VOTING PREFERENCE SHARES FOR EXCHANGEABLE SHARES,
     ANCILLARY RIGHTS AND EXCHANGEABLE SHARE RIGHTS

    Where a JDS Shareholder on the Arrangement exchanges all of such JDS
Shareholder's Class B Non-Voting Preference Shares for Exchangeable Shares,
Ancillary Rights and Exchangeable Share Rights, the JDS Shareholder will not
realize a capital gain provided the adjusted cost base to the shareholder of the
shareholder's Class B Non-Voting Preference Shares exceeds the sum of:

    (i) any cash received in lieu of a fractional Exchangeable Share; and

    (ii) the fair market value of the Ancillary Rights and Exchangeable Share
         Rights received on the exchange.

    A JDS Shareholder will realize a capital gain to the extent that such sum,
net of any reasonable costs of disposition, exceeds the adjusted cost base of
the Class B Non-Voting Preference Shares to the JDS Shareholder immediately
before the exchange.

    A JDS Shareholder will be deemed to have acquired the Ancillary Rights and
the Exchangeable Share Rights at a cost equal to their fair market value and to
have acquired the Exchangeable Shares at a cost equal to the amount, if any, by
which the adjusted cost base to the JDS Shareholder of the Class B Non-Voting
Preference Shares immediately before the exchange exceeds the sum of:

    (i) any cash received in lieu of a fractional Exchangeable Share; and

    (ii) the fair market value of the Ancillary Rights and Exchangeable Share
         Rights received on the exchange.

    A JDS Shareholder will be required to determine the fair market value of the
Ancillary Rights and the Exchangeable Share Rights received on the exchange on a
reasonable basis for purposes of the Canadian Tax Act. JDS' financial advisor,
CIBC World Markets, is of the view that both the Ancillary Rights and the

                                     S-148

Exchangeable Share Rights have only nominal value. Any determination of value is
not binding on Revenue Canada. Counsel expresses no opinion as to the
appropriateness or accuracy of this valuation. It is possible that Revenue
Canada could take the position that the Ancillary Rights and the Exchangeable
Share Rights have a fair market value in excess of a nominal amount.

    CALL RIGHTS

    JDS' financial advisor, CIBC World Markets, is of the view that the
Liquidation Call Right, the Redemption Call Right and the Retraction Call Right
have nominal fair market value and that accordingly, no amount should be
allocated to the Call Rights. Counsel expresses no opinion as to the
appropriateness or accuracy of this valuation. Any determination of value is not
binding upon Revenue Canada. Provided that the valuation with respect to such
Call Rights is correct, the granting of the Call Rights will not result in any
material adverse income tax consequences to JDS Shareholders. However, should
Revenue Canada challenge this valuation and ultimately succeed in establishing
that the Call Rights have a fair market value in excess of a nominal amount, JDS
Shareholders will realize a capital gain in an amount equal to the fair market
value of the Call Rights. The general tax treatment of capital gains and capital
losses is discussed below under the heading "Taxation of Capital Gain or Capital
Loss".

    DIVIDENDS

    DIVIDENDS ON EXCHANGEABLE SHARES.  In the case of a JDS Shareholder who is
an individual, dividends received or deemed to be received on the Exchangeable
Shares will be required to be included in computing the JDS Shareholder's income
and will be subject to the gross-up and dividend tax credit rules normally
applicable to taxable dividends received from a corporation resident in Canada.

    Subject to the discussion below as to the denial of the dividend deduction,
in the case of a JDS Shareholder that is a corporation, other than a "specified
financial institution" as defined in the Canadian Tax Act, dividends received or
deemed to be received on the Exchangeable Shares will be included in computing
the corporation's income and will generally be deductible in computing its
taxable income. In the case of a JDS Shareholder that is a specified financial
institution, such a dividend will be deductible in computing its taxable income
only if either: (i) the specified financial institution did not acquire the
Exchangeable Shares in the ordinary course of the business carried on by such
institution; or (ii) at the time of the receipt of the dividend by the specified
financial institution, the Exchangeable Shares are listed on a prescribed stock
exchange in Canada (which currently includes the TSE) and the specified
financial institution, either alone or together with persons with whom it does
not deal at arm's length, does not receive (or is not deemed to receive)
dividends in respect of more than 10% of the issued and outstanding Exchangeable
Shares.

    If Uniphase or any other person with whom Uniphase does not deal at arm's
length is a specified financial institution at a point in time that a dividend
is paid on an Exchangeable Share, then subject to the exemption described below,
dividends received or deemed to be received by a JDS Shareholder that is a
corporation will not be deductible in computing taxable income but will be fully
includable in taxable income under Part I of the Canadian Tax Act. A corporation
is a specified financial institution for purposes of the Canadian Tax Act if it
is a bank, a trust company, a credit union, an insurance corporation or a
corporation whose principal business is the lending of money to persons with
whom the corporation is dealing at arm's length or the purchasing of debt
obligations issued by such persons or a combination thereof, and corporations
controlled by or related to such entities. Uniphase has informed counsel that it
is of the view that neither it nor any person with whom it does not deal at
arm's length nor any partnership or trust of which it or the person is a member
or beneficiary, respectively, is a specified financial institution at the
current time but there can be no assurance that this status will not change
prior to any dividend received or deemed to be received by a corporate
shareholder. This denial of the dividend deduction for a JDS Shareholder that is
a corporation will not in any event apply if, at the time a dividend is received
or deemed to be received, the Exchangeable Shares are listed on a prescribed
stock exchange (which currently includes the TSE), Uniphase and Uniphase Nova
Scotia are "related" to Exchangeco for the purposes of the Canadian Tax Act and
the recipient (together with persons with whom the recipient does not deal at
arm's length or any partnership or trust of which the recipient or person is a
member or beneficiary, respectively) does not receive dividends on more than 10%
of the issued and outstanding Exchangeable Shares.

                                     S-149

    A JDS Shareholder that is a "private corporation" (as defined in the
Canadian Tax Act) or any other corporation resident in Canada and controlled or
deemed to be controlled by or for the benefit of an individual or a related
group of individuals may be liable under Part IV of the Canadian Tax Act to pay
a refundable tax of 33 1/3% on dividends received or deemed to be received on
the Exchangeable Shares to the extent that such dividends are deductible in
computing the JDS Shareholder's taxable income. A JDS Shareholder that is a
"Canadian-controlled private corporation" (as defined in the Canadian Tax Act)
may be liable to pay an additional refundable tax of 6 2/3% on dividends or
deemed dividends that are not deductible in computing taxable income.

    The Exchangeable Shares will be "taxable preferred shares" and "short-term
preferred shares" for purposes of the Canadian Tax Act. Accordingly, Exchangeco
will be subject to a 66 2/3% tax under Part VI.I of the Canadian Tax Act on
dividends paid or deemed to be paid on the Exchangeable Shares and will be
entitled to deduct 9/4 of the tax payable in computing its taxable income under
Part I of the Canadian Tax Act. Dividends received or deemed to be received on
the Exchangeable Shares will not be subject to the 10% tax under Part IV.I of
the Canadian Tax Act.

    DIVIDENDS ON UNIPHASE COMMON SHARES.  Dividends on Uniphase Common Shares
will be required to be included in the recipient's income for the purposes of
the Canadian Tax Act. Such dividends received by a JDS Shareholder who is an
individual will not be subject to the gross-up and dividend tax credit rules in
the Canadian Tax Act. A JDS Shareholder that is a corporation will include such
dividends in computing its income and generally will not be entitled to deduct
the amount of such dividends in computing its taxable income. A JDS Shareholder
that is a Canadian-controlled private corporation may be liable to pay an
additional refundable tax of 6 2/3% on such dividends. United States
non-resident withholding tax on dividends generally will be eligible for foreign
tax credit or deduction treatment where applicable under the Canadian Tax Act.
See the commentary below under the heading "United States Federal Tax
Considerations for JDS Shareholders".

    REDEMPTION OR EXCHANGE OF EXCHANGEABLE SHARES

    On the redemption (including a retraction) of an Exchangeable Share by
Exchangeco, the holder of an Exchangeable Share will be deemed to have received
a dividend equal to the amount, if any, by which the redemption proceeds (the
fair market value at that time of Uniphase Common Shares (including any related
Uniphase Rights) received by the shareholder from Exchangeco on the redemption
plus the Dividend Amount, if any) exceeds the paid-up capital (for purposes of
the Canadian Tax Act) of the Exchangeable Share at the time the Exchangeable
Share is so redeemed. The amount of any such deemed dividend will be subject to
the tax treatment described above under the heading "Dividends -- Dividends on
Exchangeable Shares". On the redemption, the holder of an Exchangeable Share
will also be considered to have disposed of the Exchangeable Share and related
Exchangeable Share Right for proceeds of disposition equal to the redemption
proceeds less the amount of such deemed dividend. A holder will in general
realize a capital gain (or a capital loss) equal to the amount by which the
adjusted cost base to the holder of the Exchangeable Share and Exchangeable
Share Right is less than (or exceeds) such proceeds of disposition. See
"Taxation of Capital Gain or Capital Loss" below. In the case of a JDS
Shareholder that is a corporation, in some circumstances the amount of any such
deemed dividend may be treated as proceeds of disposition and not as a dividend.

    On the exchange of an Exchangeable Share and related Exchangeable Share
Right by the holder thereof with Uniphase Nova Scotia or Uniphase for Uniphase
Common Shares (including any related Uniphase Rights), the holder will in
general realize a capital gain (or a capital loss) to the extent the proceeds of
disposition of the Exchangeable Share and Exchangeable Share Right, net of any
reasonable costs of disposition, exceed (or are less than) the adjusted cost
base to the holder of the Exchangeable Share and Exchangeable Share Right. For
these purposes, the proceeds of disposition will be the aggregate of the fair
market value, at the time of the exchange, of the Uniphase Common Shares
(including any related Uniphase Rights) received on the exchange, any Dividend
Amount received by the holder as part of the exchange consideration and the
amount of any cash received in lieu of a fractional share. See "Taxation of
Capital Gain or Capital Loss" below.

                                     S-150

    Because of the existence of the Call Rights, the Exchange Right and the
Automatic Exchange Right, a holder of Exchangeable Shares cannot control whether
such holder will receive Uniphase Common Shares by way of redemption of the
Exchangeable Shares by Exchangeco or by way of purchase of the Exchangeable
Shares by Uniphase or Uniphase Nova Scotia. As described above, the Canadian
federal income tax consequences of a redemption differ from those of a purchase.

    ACQUISITION AND DISPOSITION OF UNIPHASE COMMON SHARES

    The cost of Uniphase Common Shares received on the retraction, redemption or
exchange of an Exchangeable Share will be equal to the fair market value of such
Uniphase Common Shares at the time of such event, to be averaged with the
adjusted cost base of any other Uniphase Common Shares held at that time by the
holder as capital property.

    A disposition or deemed disposition of Uniphase Common Shares by a holder
will generally result in a capital gain (or capital loss) to the extent that the
proceeds of disposition, net of any reasonable costs of disposition, exceed (or
are less than) the adjusted cost base to the holder of Uniphase Common Shares
immediately before the disposition.

    TAXATION OF CAPITAL GAIN OR CAPITAL LOSS

    Three-quarters of any capital gain (the "taxable capital gain") realized by
a JDS Shareholder will be included in the JDS Shareholder's income for the year
of disposition. Three-quarters of any capital loss so realized (the "allowable
capital loss") may be deducted by the holder against taxable capital gains for
the year of disposition. Any excess of allowable capital losses over taxable
capital gains of the JDS Shareholder for the year of disposition may be carried
back up to three taxation years or forward indefinitely and deducted against net
taxable capital gains in those other years to the extent and in the
circumstances prescribed in the Canadian Tax Act.

    Capital gains realized by an individual or trust, other than certain trusts,
may give rise to alternative minimum tax under the Canadian Tax Act. A JDS
Shareholder that is a Canadian-controlled private corporation (as defined in the
Canadian Tax Act) may be liable to pay an additional refundable tax of 6 2/3% on
taxable capital gains.

    If the holder of a JDS Common Share or Exchangeable Share is a corporation,
the amount of any capital loss arising on a disposition or deemed disposition of
any such share may be reduced by the amount of dividends received or deemed to
have been received by it on such share to the extent and under circumstances
prescribed by the Canadian Tax Act. Similar rules may apply where a corporation
is a member of a partnership or a beneficiary of a trust that owns JDS Common
Shares or Exchangeable Shares or where a trust or partnership of which a
corporation is a beneficiary or a member is a member of a partnership or a
beneficiary of a trust that owns any such shares.

    DISSENTING SHAREHOLDERS

    If, on the JDS Arrangement Resolution, a JDS Shareholder exercises Dissent
Rights and receives the fair value of the holder's JDS Common Shares, the
Dissenting Shareholder will be considered to have disposed of the JDS Common
Shares for proceeds of disposition equal to the amount received by the
Dissenting Shareholder less the amount of any interest awarded by the court. Any
interest awarded to a Dissenting Shareholder by a court will be included in the
Dissenting Shareholder's income for the purposes of the Canadian Tax Act.

JDS SHAREHOLDERS NOT RESIDENT IN CANADA

    The following portion of the summary is applicable to holders of JDS Common
Shares who, for purposes of the Canadian Tax Act or any relevant bilateral
treaty, have not been and will not be resident or deemed to be resident in
Canada at any time while they have held JDS Common Shares or will hold Class B
Non-Voting Preference Shares or Uniphase Common Shares and to whom such shares
are not "taxable Canadian property" (as defined in the Canadian Tax Act) and who
do not use or hold and are not deemed to use or hold such shares

                                     S-151

in connection with carrying on a business in Canada (a "Non-Resident
Shareholder"). Special rules, which are not discussed in this summary, may apply
to a non-resident that is an insurer carrying on business in Canada and
elsewhere.

    Generally, JDS Common Shares, Class B Non-Voting Preference Shares and
Uniphase Common Shares will not be taxable Canadian property provided that such
shares are listed on a prescribed stock exchange (which currently includes the
TSE and NASDAQ), the holder does not use or hold, and is not deemed to use or
hold, such shares in connection with carrying on a business in Canada and the
holder, alone or together with persons with whom such holder does not deal at
arm's length, has not owned (or had under option) 25% or more of the issued
shares of any class or series in the capital of JDS or Uniphase, at any time
during the immediately preceding five year period.

    A Non-Resident Shareholder will not be subject to tax under the Canadian Tax
Act on the disposition of JDS Common Shares and acquisition by such holder of
Class B Non-Voting Preference Shares pursuant to the Amalgamation, on the
exchange of Class B Non-Voting Preference Shares for Uniphase Common Shares or
on the sale or other disposition of Uniphase Common Shares.

    Where a Non-Resident Shareholder receives interest consequent upon the
exercise of Dissent Rights (see "JDS Shareholders Resident in
Canada -- Dissenting Shareholders"), such amounts will be subject to Canadian
withholding tax at the rate of 25% unless the rate is reduced under the
provisions of an applicable tax treaty.

UNITED STATES FEDERAL TAX CONSIDERATIONS FOR JDS SHAREHOLDERS

    In the opinion of Simpson Thacher & Bartlett, U.S. counsel for JDS, the
following is an accurate summary of the material United States federal income
tax considerations applicable to U.S. Holders who receive Uniphase Common Shares
and Non-U.S. Holders who receive Exchangeable Shares or Uniphase Common Shares
pursuant to the Arrangement. For purposes of this discussion, the Arrangement
includes both the conversion of JDS Common Shares into Class B Non-Voting
Preference Shares and the subsequent exchange of Class B Non-Voting Preference
Shares for either Uniphase Common Shares or Exchangeable Shares. As used herein,
a "U.S. Holder" is a beneficial owner of Uniphase Common Shares or Exchangeable
Shares who is (a) a citizen or resident of the United States, (b) a corporation
or partnership created or organized in or under the laws of the United States or
of any political subdivision thereof, (c) an estate the income of which is
subject to United States federal income taxation regardless of its source or (d)
a trust (i) that is subject to the supervision of a court within the United
States and the control of one or more United States persons as described in
section 7701(a)(30) of the Code, or (ii) that has a valid election in effect
under applicable United States Treasury regulations to be treated as a United
States person. A "Non-U.S. Holder" is any beneficial owner of Uniphase Common
Shares or Exchangeable Shares other than a U.S. Holder.

    This summary does not discuss all United States federal income tax
considerations that may be relevant to U.S. Holders and Non-U.S. Holders
(collectively, "Holders") in light of their particular circumstances or to
certain Holders that may be subject to special treatment under United States
federal income tax laws (for example, insurance companies, tax-exempt
organizations, financial institutions, dealers in securities, persons who hold
JDS Common Shares as part of a straddle, hedging, constructive sale or
conversion transaction, U.S. persons whose functional currency is not the U.S.
dollar and Holders who acquired such shares through exercise of employee stock
options or otherwise as compensation for services). Furthermore, this summary
does not discuss aspects of United States federal income taxation that may be
applicable to holders of JDS Options as a result of the Arrangement, nor does it
address any aspects of foreign, state or local taxation. This summary is based
on current provisions of the Code, existing, temporary and proposed regulations
promulgated thereunder and administrative and judicial interpretations thereof,
all of which are subject to change, possibly with retroactive effect. No advance
income tax ruling has been sought or obtained from the IRS regarding the tax
consequences of the transactions described herein.

    THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, AND
SHOULD NOT BE CONSTRUED TO BE, LEGAL, BUSINESS OR TAX ADVICE TO ANY PARTICULAR
SHAREHOLDER. SHAREHOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE
UNITED STATES FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE
DESCRIBED TRANSACTIONS IN THEIR PARTICULAR CIRCUMSTANCES.

                                     S-152

U.S. HOLDERS

    The following discussion applies only to U.S. Holders who receive Uniphase
Common Shares in exchange for their JDS Common Shares pursuant to the
Arrangement. The discussion does not address U.S. Holders who are also Canadian
Residents and who elect to receive Exchangeable Shares pursuant to the
Arrangement. Such U.S. Holders should consult their tax advisors concerning the
United States tax consequences of the receipt, ownership and disposition of the
Exchangeable Shares, including the exchange of Exchangeable Shares for Uniphase
Common Shares.

    EXCHANGE OF JDS COMMON SHARES FOR UNIPHASE COMMON SHARES

    The exchange of JDS Common Shares for Uniphase Common Shares pursuant to the
Arrangement will be a taxable exchange for United States federal income tax
purposes. Consequently, a U.S. Holder will recognize gain or loss equal to the
difference between such U.S. Holder's basis in its JDS Common Shares and the sum
of (a) the fair market value at the Effective Time of the Uniphase Common Shares
received in the exchange and (b) any cash received in lieu of fractional shares.
In the case of a U.S. Holder who dissents in respect of the JDS Arrangement
Resolution, such gain or loss will be equal to the difference between the amount
received by such Dissenting Shareholder and such U.S. Holder's basis in its JDS
Common Shares in respect of which the Dissenting Shareholder dissented. Gain or
loss on the exchange of JDS Common Shares will be capital gain or loss if such
shares were held by a U.S. Holder as a capital asset, and will be long-term
capital gain or loss if the U.S. Holder had held its JDS Common Shares for more
than one year at the time of the exchange. Any long-term capital gain recognized
by an individual U.S. Holder would be subject to tax at a maximum rate of 20% if
the JDS Common Shares had been held for more than twelve months. The tax basis
of Uniphase Common Shares received by a U.S. Holder will be equal to the fair
market value of such shares on the date of the exchange. The holding period for
the Uniphase Common Shares will begin on the day after the exchange.

    DIVIDENDS ON UNIPHASE COMMON SHARES

    A U.S. Holder of Uniphase Common Shares generally will be required to
include in gross income as ordinary income dividends paid on Uniphase Common
Shares to the extent paid out of Uniphase current or accumulated earnings and
profits, as determined under United States federal income tax principles.
Distributions on Uniphase Common Shares to a U.S. Holder in excess of such
earnings and profits will be treated as a tax-free return of capital to the
extent of the U.S. Holder's adjusted tax basis for such shares and, to the
extent in excess of adjusted tax basis, as capital gain. Dividends on Uniphase
Common Shares should qualify for the dividends received deduction applicable to
U.S. corporations.

    SALE OR EXCHANGE OF UNIPHASE COMMON SHARES

    On the sale or other disposition of Uniphase Common Shares, a U.S. Holder
will recognize capital gain or loss equal to the difference between the amount
realized on such sale and the U.S. Holder's adjusted tax basis in such Uniphase
Common Shares. Gain or loss will be capital gain or loss if the Uniphase Common
Shares were held by such U.S. Holder as a capital asset, and will be long-term
capital gain or loss if the U.S. Holder had held the shares for more than one
year. Any long-term capital gain recognized by an individual U.S. Holder would
be subject to tax at a maximum rate of 20% if the shares had been held for more
than twelve months.

NON-U.S. HOLDERS

    EXCHANGE OF JDS COMMON SHARES

    Non-U.S. Holders will not be subject to United States federal income tax as
a result of an exchange of JDS Common Shares for Exchangeable Shares, Uniphase
Common Shares, cash or a combination thereof pursuant to the Arrangement, unless
any gain is effectively connected with a United States trade or business of the
Non-U.S. Holder or, in the case of gain recognized by an individual Non-U.S.
Holder, such individual is present in the United States for 183 days or more
during the taxable year of disposition and certain other conditions are
satisfied.

                                     S-153

    EXCHANGEABLE SHARES

    DIVIDENDS ON EXCHANGEABLE SHARES.  Dividends received by a Non-U.S. Holder
on Exchangeable Shares should not be subject to United States withholding tax,
and therefore Uniphase and its affiliates do not intend to withhold any amounts
in respect of such tax from such dividends. The IRS may, however, assert that
United States withholding tax is payable with respect to dividends paid on the
Exchangeable Shares to Non-U.S. Holders. As a result, Non-U.S. Holders of
Exchangeable Shares could be subject to United States withholding tax at a rate
of 30%. The withholding rate may be reduced by an applicable income tax treaty
in effect between the United States and the Non-U.S. Holder's country of
residence. Under the Tax Treaty, a maximum rate of 15% applies to dividends paid
to Canadian Residents.

    SALE OR EXCHANGE OF EXCHANGEABLE SHARES.  A Non-U.S. Holder generally will
not be subject to United States federal income tax on any gain realized on the
sale or exchange of Exchangeable Shares, including the exchange of Exchangeable
Shares for Uniphase Common Shares, unless such gain is effectively connected
with a United States trade or business of the Non-U.S. Holder or, in the case of
gain recognized by an individual Non-U.S. Holder, such individual is present in
the United States for 183 days or more during the taxable year of disposition
and certain other conditions are satisfied.

    UNIPHASE COMMON SHARES

    DIVIDENDS ON UNIPHASE COMMON SHARES.  Dividends paid to a Non-U.S. Holder of
Uniphase Common Shares generally will be subject to withholding of United States
federal income tax at a rate of 30% (or such lower rate as may be specified by
an applicable income tax treaty) unless the dividend is (a) effectively
connected with the conduct of a trade or business of the Non-U.S. Holder within
the United States, or (b) if a tax treaty applies, attributable to a United
States permanent establishment of the Non-U.S. Holder, in which cases the
dividend will be taxed at ordinary United States federal income tax rates. If
the Non-U.S. Holder is a corporation, such effectively connected income may also
be subject to an additional "branch profits tax". A Non-U.S. Holder may be
required to satisfy certain certification requirements to claim treaty benefits
or otherwise claim a reduction of, or exemption from, the withholding obligation
described above.

    SALE OR EXCHANGE OF UNIPHASE COMMON SHARES.  A Non-U.S. Holder generally
will not be subject to United States federal income or withholding tax in
respect of any gain recognized on the sale or other taxable disposition of
Uniphase Common Shares unless (a) the gain is effectively connected with a trade
or business of the Non-U.S. Holder in the United States; (b) in the case of a
Non-U.S. Holder who is an individual and holds the shares as a capital asset,
the Non-U.S. Holder is present in the United States for 183 or more days during
the taxable year of the disposition and satisfies certain other conditions; or
(c) (i) Uniphase is or has been during certain periods preceding the disposition
a "U.S. real property holding corporation" for United States federal income tax
purposes (which Uniphase does not believe it is or is likely to become), and
(ii) assuming that Uniphase Common Shares will be "regularly traded on an
established securities market" for United States federal income tax purposes,
the Non-U.S. Holder held, directly or indirectly, at any time during the
five-year period ending on the date of disposition, more than 5% of the
outstanding Uniphase Common Shares.

    BACKUP WITHHOLDING AND INFORMATION REPORTING

    DIVIDENDS.  Until January 1, 2001, United States backup withholding tax
generally will not apply to dividends paid on Uniphase Common Shares to a
Non-U.S. Holder at an address outside the United States. Uniphase must report
annually to the IRS and to each Non-U.S. Holder the amount of dividends paid to,
and the tax withheld with respect to, such Non-U.S. Holder, regardless of
whether any tax was actually withheld. This information may also be made
available to the tax authorities in the Non-U.S. Holder's country of residence.

    SALE OR EXCHANGE OF UNIPHASE COMMON SHARES.  Upon the sale or other
disposition of Uniphase Common Shares by a Non-U.S. Holder to or through a
United States office of a broker, the broker must backup withhold at a rate of
31% and report the sale to the IRS, unless the Non-U.S. Holder certifies its
Non-U.S. Holder status under penalties of perjury or otherwise establishes an
exemption. Upon the sale or other disposition of Uniphase Common Shares by a
Non-U.S. Holder to or through the foreign office of a United States broker, or a
foreign broker with certain types of relationships to the United States, the
broker must report the sale to the IRS

                                     S-154

(but not backup withhold), unless the broker has documentary evidence in its
files that the seller is a Non-U.S. Holder and/or certain other conditions are
met, or the Non-U.S. Holder otherwise establishes an exemption.

    Amounts withheld under the backup withholding rules are generally allowable
as a credit against such Non-U.S. Holder's United States federal income tax
liability (if any), which may entitle such Non-U.S. Holder to a refund, provided
that the required information is furnished to the IRS.

    On October 6, 1997, the IRS issued final regulations relating to
withholding, information reporting and backup withholding that unify certain
certification procedures and forms and clarify reliance standards (the "Final
Regulations"). The Final Regulations will be effective with respect to payments
made after December 31, 2000. The Final Regulations eliminate the general prior
legal presumption that dividends paid to an address in a foreign country are
paid to a resident of that country. In addition, the Final Regulations impose
certain certification and documentation requirements on Non-U.S. Holders
claiming the benefit of a reduced withholding rate with respect to dividends
under a tax treaty or otherwise claiming a reduction of, or exemption from, the
withholding obligation described above. Non-U.S. Holders are urged to consult
their own tax advisors as to the effect, if any, of the Final Regulations on
their ownership and disposition of the Uniphase Common Shares.

                        COMPARISON OF SHAREHOLDER RIGHTS

    JDS is incorporated under the CBCA and, accordingly, is governed by the laws
of Canada and the JDS Articles and the JDS By-Laws. Uniphase is incorporated
under the DGCL and, accordingly, is governed by Delaware law and the Uniphase
Charter and the Uniphase Bylaws. In the event that the Transaction is
consummated, holders of JDS Common Shares at the Effective Time will have their
JDS Common Shares exchanged for Uniphase Common Shares or Exchangeable Shares,
and will have the right to exchange the Exchangeable Shares for an equivalent
number of Uniphase Common Shares.

    While the rights and privileges of shareholders of a Delaware corporation
are, in many instances, comparable to those of shareholders of a CBCA
corporation, there are certain differences. The following is a summary
discussion of the most significant differences in shareholder rights. These
differences arise from differences between Delaware and Canadian law, between
the DGCL and CBCA and between the Uniphase Charter and Uniphase Bylaws and the
JDS Articles and JDS By-Laws. This summary is not intended to be complete and is
qualified in its entirety by reference to the DGCL, the CBCA and the governing
corporate instruments of Uniphase and JDS. For a description of the respective
rights of the holders of Uniphase Common Shares and JDS Common Shares see,
respectively, "Uniphase Capital Stock" and "Business of JDS -- Share Capital of
JDS".

    Exchangeco is incorporated under the CBCA and, accordingly, is governed by
the laws of Canada and its articles and by-laws.

VOTE REQUIRED FOR EXTRAORDINARY TRANSACTIONS

    Under the CBCA, certain extraordinary corporate actions, such as certain
amalgamations (other than with a direct or indirect wholly-owned subsidiary),
continuances, and sales, leases or exchanges of all or substantially all the
property of a corporation other than in the ordinary course of business, and
other extraordinary corporate actions such as liquidations, dissolutions and (if
ordered by a court) arrangements, are required to be approved by special
resolution. A special resolution is a resolution passed at a meeting by not less
than two-thirds of the votes cast by the shareholders who voted in respect of
the resolution. In certain cases, a special resolution to approve an
extraordinary corporate action is also required to be approved separately by the
holders of a class or series of shares, including in certain cases a class or
series of shares not otherwise carrying voting rights.

    The DGCL requires the affirmative vote of a majority of the outstanding
stock entitled to vote thereon to authorize any merger, consolidation,
dissolution or sale of substantially all of the assets of a corporation, except
that, unless required by its certificate of incorporation: (i) no authorizing
shareholder vote is required of a corporation surviving a merger if (A) such
corporation's certificate of incorporation is not amended in any respect by the
merger, (B) each share of stock of such corporation outstanding immediately
prior to the effective date of the merger will be an identical outstanding or
treasury share of the surviving corporation after the

                                     S-155

effective date of the merger, and (C) either no shares of common stock of the
surviving corporation and no shares, securities or obligations convertible into
such stock are to be issued or delivered under the plan of merger, or the
authorized unissued shares or the treasury shares of common stock of the
surviving corporation to be issued and delivered in the merger plus those
initially issuable upon conversion of any other shares, securities or
obligations to be issued in the merger do not exceed 20% of such corporation's
outstanding common stock immediately prior to the effective date of the merger;
and (ii) in certain limited circumstances, no authorizing shareholder vote is
required of a corporation to authorize a merger with or into a single direct or
indirect wholly-owned subsidiary of such corporation. Shareholder approval is
also not required under the DGCL for mergers or consolidations in which a parent
corporation merges or consolidates with a subsidiary of which it owns at least
90% of the outstanding shares of each class of stock.

CALLING A SHAREHOLDERS' MEETING

    Under the CBCA, the holders of not less than 5% of the issued shares of a
corporation that carry the right to vote at the meeting sought to be held may
requisition the directors to call a meeting of shareholders. Upon meeting the
technical requirements set out in the CBCA for making such a requisition, the
directors of the corporation must call a meeting of shareholders. If they do
not, the shareholders who made the requisition may call the meeting.

    Under the DGCL, special meetings of the stockholders may be called by the
board of directors or by such person or persons as may be authorized by the
certificate of incorporation or by the bylaws of a corporation. According to the
Uniphase Charter, Uniphase Stockholders are not permitted to call (or to require
the Uniphase Board of Directors to call) a special meeting of the stockholders.

AMENDMENT TO GOVERNING DOCUMENTS

    Under the CBCA, any amendment to the articles generally requires approval by
special resolution. The CBCA provides that unless the articles or by-laws
otherwise provide, the directors may, by resolution, make, amend or repeal any
by-laws that regulate the business or affairs of a corporation. Where the
directors make, amend or repeal a by-law, they are required under the CBCA to
submit the by-law, amendment or repeal to the shareholders at the next meeting
of shareholders, and the shareholders may confirm, reject or amend the by-law,
amendment or repeal by an ordinary resolution, which is a resolution passed by a
majority of the votes cast by shareholders who voted in respect of the
resolution.

    The DGCL requires approval of a corporation's board of directors followed by
the affirmative vote of a majority of the outstanding stock entitled to vote for
any amendment to the certificate of incorporation, unless a greater level of
approval is required by the certificate of incorporation.

    The DGCL also states that the power, by a simple majority, to adopt, amend
or repeal the by-laws of a corporation shall be in the stockholders entitled to
vote. The Uniphase Charter confers such power on Uniphase's Board of Directors
in accordance with the DGCL.

DISSENTERS' RIGHTS

    The CBCA provides that shareholders of a corporation governed thereunder who
are entitled to vote on certain matters are entitled to exercise dissent rights
and to be paid the fair value of their shares in connection therewith. The CBCA
does not distinguish for this purpose between listed and unlisted shares. Such
matters include:

    (i) any amalgamation with another corporation (other than with certain
        affiliated corporations);

    (ii) an amendment to the corporation's articles to add, change or remove any
         provisions restricting the issue, transfer or ownership of shares;

   (iii) an amendment to the corporation's articles to add, change or remove any
         restriction upon the business or businesses that the corporation may
         carry on;

                                     S-156

    (iv) a continuance under the laws of another jurisdiction;

    (v) a sale, lease or exchange of all or substantially all the property of
        the corporation other than in the ordinary course of business;

    (vi) a court order permitting a shareholder to dissent in connection with an
         application to the court for an order approving an arrangement proposed
         by the corporation; or

   (vii) certain amendments to the articles of a corporation which require a
         separate class or series vote, provided that a shareholder is not
         entitled to dissent if an amendment to the articles is effected by a
         court order approving a reorganization or by a court order made in
         connection with an action for an oppression remedy.

    Under the CBCA, a shareholder may, in addition to exercising dissent rights,
seek an oppression remedy for any act or omission of a corporation which is
oppressive, unfairly prejudicial to or that unfairly disregards a shareholder's
interests.

    Under the DGCL, holders of shares of any class or series have the right, in
certain circumstances, to dissent from a merger or consolidation by demanding
payment in cash for their shares equal to the fair value (exclusive of any
element of value arising from the accomplishment or expectation of the merger or
consolidation) of such shares, as determined by a court in an action timely
brought by the corporation or the dissenters. The DGCL grants dissenters
appraisal rights only in the case of mergers or consolidations and not in the
case of a sale or transfer of assets or a purchase of assets for stock
regardless of the number of shares being issued. Further, no appraisal rights
are available for shares of any class or series listed on a national securities
exchange or designated as a national market system security on an interdealer
quotation system by the National Association of Securities Dealers, Inc. or held
of record by more than 2,000 shareholders, unless the agreement of merger or
consolidation requires the holders thereof to accept for such shares anything
other than:

    (i) stock of the surviving corporation;

    (ii) shares of stock of another corporation which shares of stock are either
         listed on a national securities exchange or designated as a national
         market system security on an interdealer quotation system by the
         National Association of Securities Dealers, Inc. or held of record by
         more than 2,000 shareholders;

   (iii) cash in lieu of fractional shares (in the case of (i) or (ii) above);
         or

    (iv) some combination of the above.

    In addition, such rights are not available for any shares of the surviving
corporation if the merger did not require the vote of the shareholders of the
surviving corporation.

OPPRESSION REMEDY

    The CBCA provides an oppression remedy that enables a court to make any
order, both interim and final, to rectify the matters complained of if the court
is satisfied upon application by a complainant (as defined below) that:

    (i) any act or omission of the corporation or an affiliate effects a result;

    (ii) the business or affairs of the corporation or an affiliate are or have
         been carried on or conducted in a manner; or

   (iii) the powers of the directors of the corporation or an affiliate are or
         have been exercised in a manner,

that is oppressive or unfairly prejudicial to or that unfairly disregards the
interest of any security holder, creditor, director or officer of the
corporation.

    A complainant includes:

    (a) a present or former registered holder or beneficial owner of securities
       of a corporation or any of its affiliates;

    (b) a present or former officer or director of the corporation or any of its
       affiliates;

                                     S-157

    (c) the Director under the CBCA; and

    (d) any other person who in the discretion of the court is a proper person
       to make such application.

    The oppression remedy provides the court with an extremely broad and
flexible jurisdiction to intervene in corporate affairs to protect "reasonable
expectations" of shareholders and other complainants. While conduct which is in
breach of fiduciary duties of directors or that is contrary to the legal right
of a complainant will normally trigger the court's jurisdiction under the
oppression remedy, the exercise of that jurisdiction does not depend on a
finding of a breach of such legal and equitable rights. Furthermore, the court
may order a corporation to pay the interim expenses of a complainant seeking an
oppression remedy, but the complainant may be held accountable for such interim
costs on final disposition of the complaint (as in the case of a derivative
action).

    The DGCL does not provide for a similar remedy.

DERIVATIVE ACTION

    Under the CBCA, a complainant may apply to the court for leave to bring an
action in the name of and on behalf of a corporation or any subsidiary, or to
intervene in an existing action to which any such body corporate is a party, for
the purpose of prosecuting, defending or discontinuing the action on behalf of
the body corporate. Under the CBCA, no action may be brought and no intervention
in an action may be made unless the complainant has given reasonable notice to
the directors of the corporation or its subsidiary of the complainant's
intention to apply to the court if (i) the directors of the corporation or its
subsidiary do not bring, diligently prosecute or defend or discontinue the
action; (ii) the complainant is acting in good faith; and (iii) it appears to be
in the interests of the corporation or its subsidiary that the action be
brought, prosecuted, defended or discontinued.

    Under the CBCA, the court in a derivative action may make any order it
thinks fit. In addition, under the CBCA, a court may order a corporation or its
subsidiary to pay the complainant's interim costs, including reasonable legal
fees and disbursements. Although the complainant may be held accountable for the
interim costs on final disposition of the complaint, it is not required to give
security for costs in a derivative action.

    Derivative actions may be brought in Delaware by a stockholder on behalf of,
and for the benefit of, a corporation governed by the DGCL. The DGCL provides
that a stockholder must aver in the complaint that he or she was a stockholder
of the corporation at the time of the transaction of which he or she complains
or that his or her stock thereafter devolved upon him or her by operation of
law. A stockholder may not sue derivatively unless he or she first makes demand
on the corporation that it bring suit and such demand has been refused, unless
it is shown that such suit would have been futile.

DIRECTOR QUALIFICATIONS

    A majority of the directors of a CBCA corporation generally must be resident
Canadians. The CBCA also requires that at least one-third of the directors of a
corporation whose securities are publicly traded not be officers or employees of
such company or any of its affiliates. The DGCL does not have comparable
requirements.

SHAREHOLDER CONSENT IN LIEU OF MEETING

    Under the DGCL, unless otherwise provided in the company's charter, any
action required to be taken or which may be taken at an annual or special
meeting of stockholders may be taken without a meeting and without prior notice
if a consent in writing is signed by the holders of outstanding stock having not
less than the minimum number of votes that would be necessary to authorize such
action at a meeting at which all shares entitled to vote were present and voted.
The Uniphase Charter prohibits Uniphase Stockholders from taking action by
written consent in lieu of a meeting. Under the CBCA, shareholder action without
a meeting may only be taken by written resolution signed by all stockholders who
would be entitled to vote thereon at a meeting. See "Uniphase Capital
Stock -- Delaware Law and Certain Charter Provisions".

                                     S-158

FIDUCIARY DUTIES OF DIRECTORS

    Directors of corporations governed by the CBCA have fiduciary obligations to
the corporation. Under the CBCA, directors must act honestly and in good faith
with a view to the best interests of the corporation, and must exercise the
care, diligence and skill that a reasonably prudent person would exercise in
comparable circumstances.

    Directors of corporations incorporated or organized under the DGCL have
fiduciary obligations to the corporation and its shareholders. Pursuant to these
fiduciary obligations, the directors must act in accordance with the so-called
duties of "due care" and "loyalty". Under the DGCL, the duty of care requires
that the directors act in an informed and deliberative manner and that they
inform themselves, prior to making a business decision, of all material
information reasonably available to them. The duty of loyalty may be summarized
as the duty to act in good faith in a manner that the directors reasonably
believe to be in the best interests of the corporation and its shareholders.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

    Under the CBCA, a corporation may indemnify a director or officer, a former
director or officer or a person who acts or acted at the corporation's request
as a director or officer of a body corporate of which the corporation is or was
a shareholder or creditor, and his or her heirs and legal representatives (an
"indemnifiable person"), against all costs, charges and expenses, including an
amount paid to settle an action or satisfy a judgment, reasonably incurred by
him or her in respect of any civil, criminal or administrative action or
proceeding to which he or she is made a party by reason of being or having been
a director or officer of such corporation or such body corporate, if: (i) he or
she acted honestly and in good faith with a view to the best interests of such
corporation; and (ii) in the case of a criminal or administrative action or
proceeding that is enforced by a monetary penalty, he or she had reasonable
grounds for believing that his or her conduct was lawful. An indemnifiable
person is entitled under the CBCA to such indemnity from the corporation if he
or she was substantially successful on the merits in his or her defence of the
action or proceeding and fulfilled the conditions set out in (i) and (ii) above.
A corporation may, with the approval of a court, also indemnify an indemnifiable
person in respect of an action by or on behalf of the corporation or body
corporate to procure a judgment in its favour, to which such person is made a
party by reason of being or having been a director or an officer of the
corporation or body corporate, if he or she fulfills the conditions set out in
(i) and (ii), above. JDS By-laws provide for indemnification of directors and
officers to the fullest extent authorized by the CBCA.

    The DGCL provides that a corporation may indemnify its present and former
directors, officers, employees and agents (each, an "indemnitee") against all
reasonable expenses (including attorneys fees) and, except in actions initiated
by or in the right of the corporation, against all judgments, fines and amounts
paid in settlement of actions brought against them, if such individual acted in
good faith and in a manner that he or she reasonably believed to be in, or not
opposed to, the best interests of the corporation and, in the case of a criminal
proceeding, had no reasonable cause to believe his or her conduct was unlawful.
The corporation shall indemnify a current or former director or officer of the
corporation to the extent that he or she is successful on the merits or
otherwise in the defence of any claim, issue or matter associated with an
action. The Uniphase Charter provides for indemnification of directors and
officers to the fullest extent authorized by the DGCL.

    The DGCL allows for the advance payment of an officer or director
indemnitee's expenses prior to the final disposition of an action, provided
that, in the case of a current director or officer, the indemnitee undertakes to
repay any such amount advanced if it is later determined that the indemnitee is
not entitled to indemnification with regard to the action for which the expenses
were advanced. Neither the CBCA nor the JDS By-Laws expressly provides for such
advance payment.

DIRECTOR LIABILITY

    The DGCL provides that the charter of a corporation may include a provision
which limits or eliminates the liability of directors to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
provided such liability does not arise from certain prescribed conduct,
including breach of the duty of loyalty, acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, the payment
of unlawful dividends or expenditure of funds for unlawful stock repurchases or
redemptions or

                                     S-159

transactions for which such director derived an improper personal benefit. The
Uniphase Charter contains a provision limiting the liability of its directors to
the fullest extent permitted by the DGCL. The CBCA does not permit any such
limitation of a director's liability.

ANTI-TAKE-OVER PROVISIONS AND INTERESTED STOCKHOLDERS

    The DGCL prohibits, in certain circumstances, a "business combination"
between the corporation and an "interested stockholder" within three years of
the stockholder becoming an "interested stockholder". An "interested
stockholder" is a holder who, directly or indirectly, controls 15% or more of
the outstanding voting stock or is an affiliate of the corporation and was the
owner of 15% or more of the outstanding voting stock at any time within the
prior three-year period. A "business combination" includes a merger,
consolidation, sale or other disposition of assets having an aggregate value in
excess of 10% of the consolidated assets of the corporation or the aggregate
market value of the assets (determined on a consolidated basis) or outstanding
stock of the corporation and certain transactions that would increase the
interested stockholder's proportionate share ownership in the corporation. This
provision does not apply where: (i) the business combination or the transaction
that resulted in the stockholder becoming an interested stockholder is approved
by the corporation's board of directors prior to the time the interested
stockholder acquired such 15% interest; (ii) upon the consummation of the
transaction that resulted in the stockholder becoming an interested stockholder,
the interested stockholder owned at least 85% of the outstanding voting stock of
the corporation excluding, for the purpose of determining the number of shares
outstanding, shares held by persons who are directors and also officers and by
employee stock plans in which participants do not have the right to determine
confidentially whether shares held subject to the plan will be tendered; (iii)
the business combination is approved by a majority of the board of directors and
the affirmative vote of two-thirds of the outstanding votes entitled to be cast
by disinterested stockholders at an annual or special meeting; (iv) the
corporation does not have a class of voting stock that is listed on a national
securities exchange, authorized for quotation on NASDAQ, or held of record by
more than 2,000 stockholders unless any of the foregoing results from action
taken, directly or indirectly, by an interested stockholder or from a
transaction in which a person becomes an interested stockholder; (v) the
corporation has opted out of this provision; or (vi) in certain other limited
circumstances. Uniphase has not opted out of this provision.

    The CBCA does not contain a comparable provision with respect to business
combinations. However, policies of certain Canadian securities regulatory
authorities, including Policy 9.1 of the OSC, contain requirements in connection
with "related party transactions". A related party transaction means, generally,
any transaction by which an issuer, directly or indirectly, acquires or
transfers an asset or acquires or issues treasury securities or assumes or
transfers a liability from or to, as the case may be, a related party by any
means in any one or any combination of transactions. "Related party" is defined
in Policy 9.1 and includes directors, senior officers and holders of at least
10% of the voting securities of the issuer.

    Policy 9.1 requires more detailed disclosure in the proxy material sent to
security holders in connection with a related party transaction, and, subject to
certain exceptions, the preparation of a formal valuation of the subject matter
of the related party transaction and any non-cash consideration offered therefor
and the inclusion of a summary of the valuation in the proxy material. Policy
9.1 also requires, subject to certain exceptions, that the shareholders of the
issuer, other than the related party and its affiliates, separately approve the
transaction, by either a simple majority or two-thirds of the votes cast,
depending on the circumstances.

                                     S-160

                         DISSENTING SHAREHOLDER RIGHTS

JDS

    Section 190 of the CBCA provides shareholders with the right to dissent from
certain resolutions of a corporation which effect extraordinary corporate
transactions or fundamental corporate changes. The Interim Order expressly
provides JDS Shareholders with the right to dissent from the JDS Arrangement
Resolution pursuant to section 190 of the CBCA and the Plan of Arrangement. Any
JDS Shareholder who dissents from the JDS Arrangement Resolution in compliance
with section 190 of the CBCA and the Plan of Arrangement will be entitled, in
the event the Arrangement becomes effective, to be paid by JDS the fair value of
the JDS Common Shares held by such Dissenting Shareholder determined as of the
close of business on the day before the JDS Arrangement Resolution is adopted.

    Section 190 provides that a shareholder may only make a claim under that
section with respect to all the shares of a class held by the shareholder on
behalf of any one beneficial owner and registered in the shareholder's name. One
consequence of this provision is that a JDS SHAREHOLDER MAY ONLY EXERCISE THE
RIGHT TO DISSENT UNDER SECTION 190 IN RESPECT OF JDS COMMON SHARES WHICH ARE
REGISTERED IN THAT SHAREHOLDER'S NAME. In many cases, shares beneficially owned
by a person (a "Non-Registered Holder") are registered either: (a) in the name
of an intermediary that the Non-Registered Holder deals with in respect of the
shares (such as banks, trust companies, securities dealers and brokers, trustees
or administrators of self-administered RRSPs, RRIFs, RESPs and similar plans,
and their nominees); or (b) in the name of a clearing agency (such as The
Canadian Depository for Securities Limited ("CDS")) of which the intermediary is
a participant. Accordingly, a Non-Registered Holder will not be entitled to
exercise the right to dissent under section 190 directly (unless the shares are
re-registered in the Non-Registered Holder's name). A Non-Registered Holder who
wishes to exercise the right to dissent should immediately contact the
intermediary with whom the Non-Registered Holder deals in respect of the shares
and either: (i) instruct the intermediary to exercise the right to dissent on
the Non-Registered Holder's behalf (which, if the shares are registered in the
name of CDS or other clearing agency, would require that the share first be
re-registered in the name of the intermediary); or (ii) instruct the
intermediary to re-register the shares in the name of the Non-Registered Holder,
in which case the Non-Registered Holder would have to exercise the right to
dissent directly.

    A REGISTERED HOLDER OF JDS COMMON SHARES (A "JDS REGISTERED SHAREHOLDER")
WHO WISHES TO DISSENT MUST PROVIDE TO JDS C/O CIBC MELLON TRUST COMPANY, PROXY
DEPARTMENT, 200 QUEENS QUAY EAST, UNIT 6, TORONTO, ONTARIO, M5A 4K9 OR BY FAX TO
(416) 368-2502 PRIOR TO 5:00 P.M. ON THE BUSINESS DAY PRECEDING THE JDS MEETING
(OR ANY ADJOURNMENT THEREOF), A DISSENT NOTICE. IT IS IMPORTANT THAT JDS
REGISTERED SHAREHOLDERS STRICTLY COMPLY WITH THIS REQUIREMENT WHICH IS DIFFERENT
FROM THE STATUTORY DISSENT PROVISIONS OF THE CBCA WHICH WOULD PERMIT A DISSENT
NOTICE TO BE PROVIDED AT OR PRIOR TO THE JDS MEETING. The filing of a Dissent
Notice does not deprive a JDS Registered Shareholder of the right to vote at the
JDS Meeting; however, the CBCA provides, in effect, that a JDS Registered
Shareholder who has submitted a Dissent Notice and who votes in favour of the
JDS Arrangement Resolution will no longer be considered a Dissenting Shareholder
with respect to that class of shares voted in favour of the JDS Arrangement
Resolution. The CBCA does not provide, and JDS will not assume, that a vote
against the JDS Arrangement Resolution or an abstention constitutes a Dissent
Notice but a JDS Registered Shareholder need not vote his or her JDS Common
Shares against the JDS Arrangement Resolution in order to dissent. Similarly,
the revocation of a proxy conferring authority on the proxy holder to vote in
favour of the JDS Arrangement Resolution does not constitute a Dissent Notice;
however, any proxy granted by a JDS Registered Shareholder who intends to
dissent, other than a proxy that instructs the proxy holder to vote against the
JDS Arrangement Resolution, should be validly revoked (see the JDS Circular,
"Revocability of Proxies") in order to prevent the proxy holder from voting such
JDS Common Shares in favour of the JDS Arrangement Resolution and thereby
causing the JDS Registered Shareholder to forfeit his or her right to dissent.

    JDS is required, within 10 days after the JDS Shareholders adopt the JDS
Arrangement Resolution, to notify each Dissenting Shareholder that the JDS
Arrangement Resolution has been adopted. Such notice is not required to be sent
to any JDS Shareholder who voted for the JDS Arrangement Resolution or who has
withdrawn his or her Dissent Notice.

                                     S-161

    A Dissenting Shareholder who has not withdrawn his or her Dissent Notice
must then, within 20 days after receipt of notice that the JDS Arrangement
Resolution has been adopted or, if the Dissenting Shareholder does not receive
such notice, within 20 days after he or she learns that the JDS Arrangement
Resolution has been adopted, send to JDS a written notice (a "Demand for
Payment"), containing his or her name and address, the number of JDS Common
Shares in respect of which he or she dissents, and a demand for payment of the
fair value of such JDS Common Shares. Within 30 days after sending a Demand for
Payment, the Dissenting Shareholder must send to JDS or its transfer agent the
certificates representing the JDS Common Shares in respect of which he or she
dissents. A Dissenting Shareholder who fails to send certificates representing
the JDS Common Shares in respect of which he or she dissents forfeits his or her
right to dissent. The JDS transfer agent will endorse on share certificates
received from a Dissenting Shareholder a notice that the holder is a Dissenting
Shareholder and will forthwith return the share certificates to the Dissenting
Shareholder.

    After sending a Demand for Payment, a Dissenting Shareholder ceases to have
any rights as a holder of the JDS Common Shares in respect of which the
shareholder has dissented other than the right to be paid the fair value of such
shares as determined under section 190, unless: (i) the Dissenting Shareholder
withdraws the Demand for Payment before JDS makes a written offer to pay (the
"Offer to Pay"); (ii) JDS fails to make a timely Offer to Pay to the Dissenting
Shareholder and the Dissenting Shareholder withdraws his or her Demand for
Payment; or (iii) the directors of JDS revoke the JDS Arrangement Resolution, in
all of which cases the Dissenting Shareholder's rights as a shareholder are
reinstated.

    In addition, pursuant to the Plan of Arrangement, JDS Registered
Shareholders who duly exercise such rights of dissent and who:

    (a) are ultimately entitled to be paid fair value for their JDS Common
       Shares shall (i) be deemed to have transferred their JDS Common Shares to
       JDS for cancellation at the Effective Time and (ii) not be entitled to
       any other payment or consideration including any payment that would be
       payable under the Arrangement had such holders not exercised their right
       of dissent; or

    (b) are ultimately not entitled, for any reason, to be paid fair value for
       their JDS Common Shares shall be deemed to have participated in the
       Arrangement on the same basis as any non-dissenting holder of JDS Common
       Shares.

    JDS is required, not later than seven days after the later of the Effective
Date and the date on which JDS received the Demand for Payment of a Dissenting
Shareholder, to send to each Dissenting Shareholder who has sent a Demand for
Payment an Offer to Pay for his or her JDS Common Shares in an amount considered
by the JDS Board of Directors to be the fair value thereof, accompanied by a
statement showing the manner in which the fair value was determined. Every Offer
to Pay must be on the same terms. JDS must pay for the JDS Common Shares of a
Dissenting Shareholder within 10 days after an Offer to Pay has been accepted by
a Dissenting Shareholder, but any such offer lapses if JDS does not receive an
acceptance thereof within 30 days after the Offer to Pay has been made.

    If JDS fails to make an Offer to Pay for a Dissenting Shareholder's JDS
Common Shares, or if a Dissenting Shareholder fails to accept an offer which has
been made, JDS may, within 50 days after the Effective Date or within such
further period as a court may allow, apply to a court to fix a fair value for
the JDS Common Shares of Dissenting Shareholders. If JDS fails to apply to a
court, a Dissenting Shareholder may apply to a court for the same purpose within
a further period of 20 days or within such further period as a court may allow.
A Dissenting Shareholder is not required to give security for costs in such an
application.

    Upon an application to a court, all Dissenting Shareholders whose JDS Common
Shares have not been purchased by JDS will be joined as parties and bound by the
decision of the court, and JDS will be required to notify each affected
Dissenting Shareholder of the date, place and consequences of the application
and of his or her right to appear and be heard in person or by counsel. Upon any
such application to a court, the court may determine whether any person is a
Dissenting Shareholder who should be joined as a party, and the court will then
fix a fair value for the JDS Common Shares of all Dissenting Shareholders. The
final order of a court will be rendered against JDS in favour of each Dissenting
Shareholder and for the amount of the fair value of his or her JDS Common Shares
as fixed by the court. The court may, in its discretion, allow a reasonable rate
of interest on the amount payable to each Dissenting Shareholder from the
Effective Date until the date

                                     S-162

of payment. An application to the court by either JDS or a Dissenting
Shareholder must be in the Province of Ontario.

    THE FOREGOING IS ONLY A SUMMARY OF THE DISSENTING SHAREHOLDER PROVISIONS OF
THE CBCA AND THE PLAN OF ARRANGEMENT, WHICH ARE TECHNICAL AND COMPLEX. A
COMPLETE COPY OF SECTION 190 OF THE CBCA IS ATTACHED TO THIS SUPPLEMENT AS
APPENDIX J. IT IS RECOMMENDED THAT ANY JDS SHAREHOLDER WISHING TO AVAIL HIMSELF
OR HERSELF OF HIS OR HER DISSENT RIGHTS UNDER THOSE PROVISIONS SEEK LEGAL ADVICE
AS FAILURE TO COMPLY STRICTLY WITH THE PROVISIONS OF THE CBCA AND THE PLAN OF
ARRANGEMENT MAY PREJUDICE THE RIGHT OF DISSENT. FOR A GENERAL SUMMARY OF CERTAIN
INCOME TAX IMPLICATIONS TO A DISSENTING SHAREHOLDER, SEE "TAX CONSIDERATIONS FOR
JDS SHAREHOLDERS -- CANADIAN FEDERAL INCOME TAX CONSIDERATIONS FOR JDS
SHAREHOLDERS -- JDS SHAREHOLDERS RESIDENT IN CANADA --  DISSENTING
SHAREHOLDERS".

UNIPHASE

    Under the DGCL, holders of Uniphase Common Shares who object to the
Transaction will not be entitled to demand appraisal of, or to receive payment
for, their Uniphase Common Shares.

                                 LEGAL MATTERS

    Certain legal matters in connection with the Transaction will be passed upon
by Osler, Hoskin & Harcourt, Toronto and Ottawa, Ontario and Simpson Thacher &

                      ENFORCEABILITY OF CIVIL LIABILITIES

    JDS is a corporation incorporated under the laws of Canada. Most of the
directors and officers of JDS, as well as certain experts named herein, are
residents of Canada and all or a substantial portion of their assets and a
substantial portion of the assets of JDS are located outside the United States.
As a result, it may be difficult for holders of JDS Common Shares to effect
service within the United States upon such directors, officers and experts who
are not residents of the United States or to realize in the United States upon
judgments of courts of the United States predicated upon civil liability under
the United States federal securities laws. There is some doubt as to the
enforceability in Canada against JDS or any of its directors, officers or
experts who are not residents of the United States in original actions or in
actions for enforcement of judgments of United States courts, of liabilities
predicated solely upon United States federal securities laws.

           Exchangeco, and the Class B Non-Voting Preference Shares so exchanged
           shall be cancelled; and

     2.4.4.   each outstanding JDS Option will become an option (a "Replacement
     Option") to purchase a number of Uniphase Common Shares equal to the
     product of the Exchange Ratio multiplied by the number of JDS Common Shares
     subject to such JDS Option. Such Replacement Option shall provide for an
     exercise price per Uniphase Common Share equal to the exercise price per
     share of such JDS Option immediately prior to the Effective Time divided by
     the Exchange Ratio and converted into U.S. dollars based on the Noon Buying
     Rate reported by the Federal Reserve Bank on the Effective Date. If the
     foregoing calculation results in a Replacement Option being exercisable for
     a fraction of a Uniphase Common Share, then the number of Uniphase Common
     Shares subject to such Replacement Option shall be rounded down to the next
     whole number of Uniphase Common Shares and the total exercise price for the
     Replacement Option will be reduced by the exercise price of the fractional
     Uniphase Common Share. The term to expiry, conditions to and manner of
     exercising, and all other terms and conditions of such Replacement Option
     will otherwise be unchanged from those of the JDS Options, and any document
     or agreement previously evidencing a JDS Option shall thereafter evidence
     and be deemed to evidence such Replacement Option; provided that,
     immediately prior to the Effective Time, the Board of Directors of JDS may
     resolve to accelerate the vesting schedule for all or a portion of the JDS
     Options such that, immediately following the Effective Time, the
     corresponding Replacement Options shall be immediately exercisable.

                                      A-12

2.5.  INFORMATION CIRCULARS

     As promptly as practicable after the execution and delivery of this
Agreement, and in any event within 21 days thereafter, Uniphase and JDS shall
revise the Uniphase Circular currently filed with the SEC, together with any
other documents required by the Securities Act and the United States Securities
Exchange Act of 1934, as amended (the "1934 Act") or other applicable Laws in
connection with the Arrangement, file such revised Uniphase Circular and other
documents with the SEC, and correspondingly revise the JDS Circular. Within five
Business Days after any applicable consents and approvals of the Uniphase
Circular have been obtained from the SEC, and provided that the Interim Order
has been obtained by such time, JDS and Uniphase shall cause the JDS Circular or
the Uniphase Circular, as applicable, and other documentation required in
connection with the Meetings to be sent to each holder of JDS Common Shares and
Uniphase Common Shares and filed as required by the Interim Order and applicable
Laws.

2.6.  SECURITIES COMPLIANCE

     2.6.1.   Uniphase and JDS shall use all reasonable efforts to obtain all
     orders required from the applicable Canadian securities authorities to
     permit the issuance and exchange of the Class B Non-Voting Preference
     Shares and the issuance and first resale of (a) the Exchangeable Shares and
     Uniphase Common Shares issued pursuant to the Arrangement, (b) the Uniphase
     Common Shares issued upon exchange of the Exchangeable Shares from time to
     time, and (c) the Uniphase Common Shares issued from time to time upon the
     exercise of the Replacement Options, in each case without qualification
     with or approval of or the filing of any document, including any prospectus
     or similar document, or the taking of any proceeding with, or the obtaining
     of any further order, ruling or consent from, any Governmental Entity or
     regulatory authority under any Canadian federal, provincial or territorial
     securities or other Laws or pursuant to the rules and regulations of any
     regulatory authority administering such Laws, or the fulfillment of any
     other legal requirement in any such jurisdiction (other than, with respect
     to such first resales, any restrictions on transfer by reason of, among
     other things, a holder being a "control person" of Uniphase or JDS for
     purposes of Canadian federal, provincial or territorial securities Laws).

     2.6.2.   Uniphase shall file a registration statement on Form S-3 (or other
     applicable form) (the "Form S-3") in order to register under the United
     States Securities Act of 1933, as amended (the "1933 Act"), the Uniphase
     Common Shares to be issued from time to time after the Effective Time upon
     exchange of the Exchangeable Shares, and shall use its reasonable
     commercial efforts to cause the Form S-3 to become effective at or prior to
     the Effective Time and to maintain the effectiveness of such registration
     for the period that such Exchangeable Shares remain outstanding.

     2.6.3.   Uniphase shall file a registration statement on Form S-8 (or other
     applicable forms) (the "Form S-8") in order to register under the 1933 Act,
     the Uniphase Common Shares to be issued from time to time after the
     Effective Time upon the exercise of the Replacement Options, and shall use
     reasonable commercial efforts to cause the Form S-8 to become effective at
     or prior to the Effective Time and to maintain the effectiveness of such
     registration for the period of time that the Replacement Options remain
     outstanding and may be exercised.

2.7.  PREPARATION OF FILINGS

     2.7.1.   Uniphase and JDS shall cooperate in:

           2.7.1.1.  the preparation of any application for the orders and the
           preparation of any required registration statements and any other
           documents reasonably deemed by Uniphase or JDS to be necessary to
           discharge their respective obligations under United States and
           Canadian federal, provincial, territorial or state securities Laws in
           connection with the Arrangement and the other transactions
           contemplated hereby;

           2.7.1.2.  the taking of all such action as may be required under any
           applicable United States and Canadian federal, provincial,
           territorial or state securities Laws (including "blue sky laws") in
           connection with the issuance of the Class B Non-Voting Preference
           Shares, the Exchangeable Shares and the Uniphase Common Shares in
           connection with the Arrangement or the exercise of

                                      A-13

           the Replacement Options; provided, however, that with respect to the
           United States "blue sky" and Canadian provincial qualifications
           neither Uniphase nor JDS shall be required to register or qualify as
           a foreign corporation or to take any action that would subject it to
           service of process in any jurisdiction where such entity is not now
           so subject, except as to matters and transactions arising solely from
           the offer and sale of the Class B Non-Voting Preference Shares, the
           Exchangeable Shares, and the Uniphase Common Shares; and

           2.7.1.3.  the taking of all such action as may be required under the
           CBCA in connection with the transactions contemplated by this
           Agreement and the Plan of Arrangement.

     2.7.2.   Each of Uniphase and JDS shall furnish to the other all such
     information concerning it and its shareholders as may be required for the
     effectuation of the actions described in sections 2.5 and 2.6 and the
     foregoing provisions of this section 2.7, and each covenants that no
     information furnished by it in connection with such actions or otherwise in
     connection with the consummation of the Arrangement and the other
     transactions contemplated by this Agreement will contain any untrue
     statement of a material fact or omit to state a material fact required to
     be stated in any such document or necessary in order to make any
     information so furnished for use in any such document not misleading in the
     light of the circumstances in which it is furnished or to be used.

     2.7.3.   Uniphase and JDS shall each promptly notify the other if at any
     time before the Effective Time it becomes aware that the Uniphase Circular
     or the JDS Circular or an application for an order or a registration
     statement described in section 2.6 contains any untrue statement of a
     material fact or omits to state a material fact required to be stated
     therein or necessary to make the statements contained therein not
     misleading in light of the circumstances in which they are made, or that
     otherwise requires an amendment or supplement to the Uniphase Circular or
     the JDS Circular or such application or registration statement. In any such
     event, Uniphase and JDS shall cooperate in the preparation of a supplement
     or amendment to the Uniphase Circular or the JDS Circular or such other
     document, as required and as the case may be, and, if required, shall cause
     the same to be distributed to shareholders of Uniphase or JDS and/or filed
     with the relevant securities regulatory authorities.

     2.7.4.   Each of JDS and Uniphase shall ensure that the JDS Circular and
     the Uniphase Circular, respectively, complies with all applicable Laws and,
     without limiting the generality of the foregoing, that neither the JDS
     Circular nor the Uniphase Circular, as the case may be, contains any untrue
     statement of a material fact or omits to state a material fact required to
     be stated therein or necessary to make the statements contained therein not
     misleading in light of the circumstances in which they are made (other than
     with respect to any information relating to and provided by the other party
     hereto). Without limiting the generality of the foregoing, JDS shall ensure
     that the JDS Circular provides holders of JDS Common Shares with
     information in sufficient detail to permit them to form a reasoned judgment
     concerning the matters to be placed before them at the JDS Meeting and
     Uniphase shall ensure that the Uniphase Circular provides holders of
     Uniphase Common Shares with information in sufficient detail to permit them
     to form a reasoned judgment concerning the matters to be placed before them
     at the Uniphase Meeting.

                         REPRESENTATIONS AND WARRANTIES

3.1.  REPRESENTATIONS AND WARRANTIES OF JDS

     Each of the representations and warranties contained in this section 3.1 is
stated as of January 28, 1999, with the exception of the representations and
warranties contained in section 3.1.3 which are stated as of the date hereof.
JDS represents and warrants to and in favour of the Uniphase Parties, except as
otherwise provided in the JDS Disclosure Letter, as follows and acknowledges
that the Uniphase Parties are relying upon such representations and warranties
in connection with the matters contemplated by this Agreement:

     3.1.1.  ORGANIZATION.

           3.1.1.1.  JDS has been duly incorporated or formed under all
           applicable Laws, is validly subsisting and has full corporate or
           legal power and capacity to own its properties and conduct its
           businesses as currently owned and conducted. All of the outstanding
           shares of capital stock and other ownership interests of its
           subsidiaries are validly issued, fully paid and non-assessable and
           all such shares and other ownership interests are owned directly or
           indirectly by JDS, free and clear of all material liens, claims or
           encumbrances and there are no outstanding options, rights,
           entitlements, understandings or commitments (pre-emptive, contingent
           or otherwise) regarding the right to acquire any such shares of
           capital stock or other ownership interests in any of its
           subsidiaries. JDS has disclosed in the JDS Disclosure Letter the
           names and jurisdictions of incorporation of each of its subsidiaries.

           3.1.1.2.  JDS does not have any subsidiaries which are material in
           relation to the business and financial condition of JDS on a
           consolidated basis; for the purposes hereof, a subsidiary and its
           subsidiaries shall be considered material in relation to JDS if (i)
           the investments in and advances to the subsidiary and its
           subsidiaries by JDS and its other subsidiaries exceed five percent of
           the total assets of JDS and its subsidiaries on a consolidated basis
           as at May 31, 1998; or (ii) the equity of JDS and its other
           subsidiaries in the income from continuing operations before income
           taxes and extraordinary items of the subsidiary and its subsidiaries
           exceeds five percent of such income of JDS and its subsidiaries on a
           consolidated basis for JDS' fiscal year ended May 31, 1998.

           3.1.1.3.  JDS does not have any ownership interest in any other
           Person, which interest is material in relation to the consolidated
           financial position of JDS.

     3.1.2.   CAPITALIZATION.  The authorized capital of JDS consists of an
     unlimited number of preference shares, issuable in series, and an unlimited
     number of JDS Common Shares. As of December 31, 1998 there were no
     preference shares issued or outstanding and 77,973,818 JDS Common Shares
     outstanding, and 4,542,078 JDS Common Shares were reserved, in the
     aggregate, for issuance in respect of the JDS Options. Except as described
     in the immediately preceding sentence, there are no options, warrants,
     conversion privileges or other rights, agreements, arrangements or
     commitments (pre-emptive, contingent or otherwise) obligating JDS or any
     subsidiary to issue or sell any shares of JDS or any of its subsidiaries or
     securities or obligations of any kind convertible into or exchangeable for
     any shares of JDS, any subsidiary or any other Person, nor is there
     outstanding any stock appreciation rights, phantom equity or similar
     rights, agreements, arrangements or commitments based upon the book value,
     income or any other attribute of JDS or any subsidiary. There have been no
     JDS Common Shares issued since November 30, 1998. All outstanding JDS
     Common Shares have been duly authorized and are validly issued and
     outstanding as fully paid and non-assessable shares, free of pre-emptive
     rights. There are no outstanding bonds, debentures or other evidences of
     indebtedness of JDS or any subsidiary having the right to vote (or that are
     convertible for or exercisable into securities having the right to vote)
     with the holders of the JDS Common Shares on any matter. There are no
     outstanding contractual obligations of JDS or any of its subsidiaries to
     repurchase, redeem or otherwise acquire any of its outstanding securities
     or with respect to the voting or disposition of any outstanding securities
     of any of its subsidiaries. No holder of securities issued by JDS has any
     right to compel JDS to register or otherwise qualify such securities for
     public sale in Canada or the United States.

                                      A-15

     3.1.3.  AUTHORITY AND NO VIOLATION.

           3.1.3.1.  JDS has the requisite corporate power and authority to
           enter into this Agreement, and to perform its obligations hereunder.
           The execution and delivery of this Agreement by JDS and the
           consummation of the transactions contemplated by this Agreement, have
           been duly authorized by its Board of Directors and no other corporate
           proceedings on its part are necessary to authorize this Agreement, or
           the transactions contemplated hereby other than:

                   3.1.3.1.1.  with respect to the JDS Circular and other
                   matters relating solely to the implementation of the
                   Arrangement, the approval of the Board of Directors of JDS;
                   and

                   3.1.3.1.2.  with respect to the completion of the
                   Arrangement, the approval of at least two-thirds of the votes
                   cast by the holders of the JDS Common Shares represented at
                   the JDS Meeting.

           3.1.3.2.  This Agreement has been duly executed and delivered by JDS
           and constitutes its legal, valid and binding obligation, enforceable
           against it in accordance with its terms, subject to bankruptcy,
           insolvency and other similar Laws affecting creditors' rights
           generally, and to general principles of equity.

           3.1.3.3.  The Board of Directors of JDS has (A) determined
           unanimously that the Arrangement is fair to the holders of the JDS
           Common Shares and is in the best interests of JDS, (B) received an
           opinion from CIBC Wood Gundy Securities Inc. that the transactions
           contemplated by this Agreement are fair from a financial point of
           view to the holders of the JDS Common Shares, (C) determined to
           recommend that the holders of the JDS Common Shares vote in favor of
           the Arrangement and (D) advised JDS that the members of the Board of
           Directors will vote the JDS Common Shares held by them directly or
           through a corporation wholly-owned by them in favor of the
           Arrangement and will so represent in the JDS Circular;

           3.1.3.4.  The approval of this Agreement by JDS, the execution and
           delivery by JDS of this Agreement, and the performance by it of its
           obligations hereunder and the completion by it of the Arrangement and
           the transactions contemplated thereby, will not:

                   3.1.3.4.1.  result in a violation or breach of, require any
                   consent to be obtained under or give rise to any material
                   termination rights or material payment obligation under any
                   provision of:

                       3.1.3.4.1.1.   its certificate of incorporation,
                       articles, by-laws or other charter documents;

                       3.1.3.4.1.2.   subject to obtaining the Appropriate
                       Regulatory Approvals relating to JDS, any Laws,
                       regulation, order, judgement or decree; or

                       3.1.3.4.1.3.   any Material Contract or material license,
                       franchise or permit to which JDS is a party or by which
                       it is bound;

                   3.1.3.4.2.  give rise to any right of termination or
                   acceleration of indebtedness, or cause any third party
                   indebtedness to come due before its stated maturity or cause
                   any available credit to cease to be available;

                   3.1.3.4.3.  except as would not, individually or in the
                   aggregate, have a Material Adverse Effect on JDS, result in
                   the imposition of any encumbrance, charge or lien upon any of
                   its assets, or restrict, hinder, impair or limit the ability
                   of JDS to carry on the business of JDS as and where it is now
                   being carried on; or

                   3.1.3.4.4.  except for the acceleration of vesting schedules
                   for the JDS Options as contemplated by section 2.4.4 and the
                   employment contracts contemplated by section 5.10, result in
                   any payment (including severance, unemployment compensation,
                   golden parachute, bonus or otherwise) becoming due to any
                   director or employee of

                                      A-16

                   JDS or any subsidiary or increase any benefits otherwise
                   payable under the JDS Plan or any JDS Employee Plan (as
                   defined in section 3.1.22) or result in the acceleration of
                   time of payment or vesting of any such benefits, including
                   the time of exercise of stock options.

     No consent, approval, order or authorization of, or declaration or filing
     with or notice to, any Governmental Entity or other Person is required to
     be obtained by JDS and its subsidiaries in connection with the execution
     and delivery of this Agreement by JDS or the consummation by JDS of the
     transactions contemplated hereby other than (A) any approvals required by
     the Interim Order, (B) the Final Order, (C) filings with the Director under
     the CBCA, (D) the Appropriate Regulatory Approvals relating to JDS and (E)
     any other consents, approvals, orders, authorizations, declarations or
     filings of or with a Governmental Entity which, if not obtained, would not
     individually or in the aggregate have a Material Adverse Effect.

     3.1.4.   NO DEFAULTS.  Neither JDS nor any of its subsidiaries is in
     default under, and there exists no event, condition or occurrence which,
     after notice or lapse of time or both, would constitute such a default
     under any contract, agreement, license or franchise to which it is a party
     which would, if terminated due to such default, cause a Material Adverse
     Effect.

     3.1.5.  INTELLECTUAL PROPERTY.

           3.1.5.1.  The JDS Disclosure Letter contains a complete and accurate
           listing of all (i) registrations and applications relating to
           Intellectual Property which are owned by JDS or its subsidiaries and
           (ii) Licensed Intellectual Property material to JDS' business and the
           governing License Agreements.

           3.1.5.2.  Except as disclosed in the JDS Disclosure Letter:

                   3.1.5.2.1.  JDS or its subsidiaries own the Intellectual
                   Property and have the right to use the Licensed Intellectual
                   Property used in JDS' business as currently conducted and
                   material thereto ("JDS Intellectual Property" and "JDS
                   Licensed Intellectual Property", respectively);

                   3.1.5.2.2.  to the knowledge of JDS, all of the registered
                   Intellectual Property listed in the JDS Disclosure Letter is
                   duly and validly registered. JDS or a subsidiary of JDS is
                   the owner of all JDS Intellectual Property, with good and
                   marketable title thereto, free and clear of any and all
                   liens;

                   3.1.5.2.3.  to the knowledge of JDS, the JDS Intellectual
                   Property and the conduct of the business of JDS and its
                   subsidiaries do not infringe upon, violate or breach the
                   Intellectual Property rights of any other Person;

                   3.1.5.2.4.  there has been no unauthorized or improper use by
                   JDS or its subsidiaries of the JDS Intellectual Property
                   which has affected or could reasonably be expected to affect
                   the validity or distinctiveness thereof or rights therein;

                   3.1.5.2.5.  to the knowledge of JDS no Person is infringing
                   any of the JDS Intellectual Property; and

                   3.1.5.2.6.  neither JDS nor any subsidiary has received any
                   written notice or claim challenging JDS or its subsidiaries
                   respecting the validity of, use of or ownership of the JDS
                   Intellectual Property, and to the knowledge of JDS, there are
                   no facts upon which such a challenge could be made.

     3.1.6.   YEAR 2000 COMPLIANCE.  To JDS' knowledge, none of JDS' systems
     (including, without limitation, JDS' telecommunications, automation and
     computer related systems), assets or technology, including without
     limitation, JDS' Intellectual Property (including, without limitation, all
     computer software (including embedded software) and hardware owned or
     licensed by JDS or its subsidiaries or used by any of them) has or will
     have any Year 2000 Error (as hereinafter defined). For the purposes hereof,
     "Year 2000 Error" means (a) any failure of computer hardware or software
     products or technology properly to

                                      A-17

     record, store, process, calculate or present calendar dates falling on and
     after (and if applicable, spans of time including) January 28, 1999 as a
     result of the occurrence, or use of data consisting of, such dates; (b) any
     failure of computer hardware or software products or technology to
     calculate any information dependent on or relating to dates on or after
     January 28, 1999 in the same manner, and with the same functionality, data
     integrity and performance, as such computer hardware or software products
     or technology records, stores, processes, calculates and presents calendar
     dates on or before January 28, 1999, or information dependent on or
     relating to such dates; or (c) any loss of functionality or performance
     with respect to the introduction of records or processing of data

     3.1.7.  OSC REPORTS.

           3.1.7.1.  JDS has furnished or made available to Uniphase true and
           complete copies of all forms, reports, schedules, prospectuses,
           statements and other documents filed by it with the OSC since March
           1, 1996 and, prior to the Effective Time, JDS will have furnished
           Uniphase with true and complete copies of any additional documents
           filed with the OSC by JDS prior to the Effective Time (such forms,
           reports, schedules, prospectuses, statements and other documents,
           including any financial statements or other documents, including any
           schedules included therein, are referred to as the "JDS Documents").

           3.1.7.2.  The JDS Documents are all forms, reports, schedules,
           prospectuses, statements or other documents required to be filed by
           it with the OSC since March 1, 1996. The JDS Documents, at the time
           filed, (i) did not contain any misrepresentation (as defined in the
           Securities Act) and (ii) complied in all material respects with the
           requirements of applicable securities Laws.

           3.1.7.3.  JDS has not filed any confidential material change report
           with the OSC or any other securities authority or regulator or any
           stock exchange or other self-regulatory authority which at January
           28, 1999 remains confidential.

           3.1.7.4.  JDS has publicly disclosed in the JDS Documents any
           information regarding any event, circumstance or action taken or
           failed to be taken by JDS or its subsidiaries which could
           individually or in the aggregate reasonably be expected to have a
           Material Adverse Effect.

     3.1.8.   FINANCIAL STATEMENTS.  The financial statements of JDS, including
     the notes thereto, included in the JDS Documents (the "JDS Financial
     Statements") complied as to form in all material respects with applicable
     accounting requirements and with the published rules and regulations of
     applicable Governmental Entities and the OSC with respect thereto as of
     their respective dates, and have been prepared in accordance with Canadian
     generally accepted accounting principles applied on a basis consistent
     throughout the periods indicated and consistent with each other (except as
     may be indicated in the notes thereto or, in the case of unaudited
     statements included in quarterly reports to shareholders). The JDS
     Financial Statements present fairly the consolidated financial position and
     results of operations of JDS and its subsidiaries at the dates and during
     the periods indicated therein (subject, in the case of unaudited
     statements, to normal, recurring year-end adjustments and the absence of
     notes thereto) and reflect appropriate and adequate reserves in respect of
     contingent liabilities, if any, of JDS and its subsidiaries on a
     consolidated basis. There has been no change in JDS' accounting policies,
     except as described in the notes to the JDS Financial Statements, since May
     31, 1998.

     3.1.9.   ABSENCE OF CERTAIN CHANGES.  Except as disclosed in publicly
     available reports filed by JDS with the OSC prior to January 28, 1999,
     since May 31, 1998 (the "JDS Balance Sheet Date"), JDS has conducted its
     business in the ordinary and regular course consistent with past practice
     and there has not occurred:

           3.1.9.1.  any material change (as defined in the Securities Act) in
           its affairs or in its business, assets, liabilities, financial
           condition, results of operations or prospects;

           3.1.9.2.  any acquisition, sale or transfer of any material asset of
           JDS or any of its subsidiaries other than in the ordinary course of
           business and consistent with past practice;

                                      A-18

           3.1.9.3.  any change in accounting methods or practices (including
           any change in depreciation or amortization policies or rates, or
           capitalized software policies) by JDS or any revaluation by JDS of
           any of its or any of its subsidiaries' assets;

           3.1.9.4.  any declaration, setting aside, or payment of a dividend or
           other distribution with respect to the shares of JDS, or any direct
           or indirect redemption, purchase or other acquisition by JDS of any
           of its shares of capital stock;

           3.1.9.5.  any material contract entered into by JDS or any of its
           subsidiaries, other than in the ordinary course of business, or any
           material amendment or termination of, or default under, any material
           contract to which JDS or any of its subsidiaries is a party or by
           which it is bound;

           3.1.9.6.  any agreement by JDS or any of its subsidiaries to do any
           of the things described in the preceding clauses 3.1.9.1 through
           3.1.9.5 (other than negotiations with Uniphase and its
           representatives regarding the transactions contemplated by this
           Agreement); or

           3.1.9.7.  any agreement or arrangement to take any action which, if
           taken prior to January 28, 1999, would have made any representation
           or warranty set forth in this Agreement materially untrue or
           incorrect as of the date when made.

     3.1.10.  ABSENCE OF UNDISCLOSED LIABILITIES.  JDS has no material
     obligations or liabilities of any nature (matured or unmatured, fixed or
     contingent), other than:

           3.1.10.1. those set forth or adequately provided for in the balance
           sheet included in JDS' audited financial statements as at and for the
           period ended May 31, 1998 (the "JDS Balance Sheet");

           3.1.10.2. those incurred in the ordinary course of business and not
           required to be set forth in the JDS Balance Sheet under Canadian
           generally accepted accounting principles;

           3.1.10.3. those incurred in the ordinary course of business since the
           JDS Balance Sheet Date and consistent with past practice; and

           3.1.10.4. those incurred in connection with the execution of this
           Agreement.

     3.1.11.  MATERIAL CONTRACTS.  None of JDS, its subsidiaries, nor to the
     knowledge of JDS any of the other parties thereto, is in default or breach
     of, in any material respect, nor has JDS or its subsidiaries received any
     notice of material default or termination under, any Material Contract and,
     to the knowledge of JDS, there exists no state of facts which after notice
     or lapse of time or both would constitute such a material default or
     breach. Except for the Material Contracts disclosed in the JDS Disclosure
     Letter, none of JDS nor its subsidiaries is a party to any (i) Contract
     which involves the payment to or by JDS or its subsidiaries of more than
     US$5,000,000 during any remaining year of the Contract or (ii) Contract not
     made in the ordinary course of business or which creates liabilities or
     obligations which are not in the ordinary course of business. True and
     complete copies of all JDS' Material Contracts, or where such Contracts are
     oral, true and complete written summaries of the terms thereof, have been
     furnished to or made available to Uniphase.

     3.1.12.  CUSTOMERS AND SUPPLIERS.  Since the JDS Balance Sheet Date, there
     has been no termination or cancellation of, and no material modification or
     change in, the business relationship with any customer or group of
     customers which singly or in the aggregate provided more than 10% of the
     consolidated gross revenues of JDS and its subsidiaries for the fiscal year
     ended on the JDS Balance Sheet Date. JDS has no reason to believe that the
     benefits of any relationship with any of the customers or suppliers of JDS
     and its subsidiaries will not continue after the Effective Date in
     substantially the same manner as prior to January 28, 1999, assuming the
     completion on the Effective Date of the Arrangement. JDS has furnished or
     made available to Uniphase JDS' standard form product warranty provided to
     customers and except as set forth in the JDS Disclosure Letter, no JDS
     product warranty relating to a Contract for the sale of goods or services
     worth more than US$500,000 differs from the standard form in any material
     respect.

     3.1.13.  INSURANCE.  JDS has furnished or made available to Uniphase
     accurate particulars of the policies of insurance maintained by JDS and its
     subsidiaries at January 28, 1999, including the name of the insurer, the
     risks insured against and the amount of coverage. All such policies are in
     full force and effect. None of

                                      A-19

     JDS or its subsidiaries or, to the knowledge of JDS, any of the other
     parties thereto, is in default or breach of, whether as to the payment of
     premiums or otherwise, nor has JDS or its subsidiaries received any notice
     of material default or termination under, any such policy and, to the
     knowledge of JDS, there exists no state of facts which after notice or
     lapse of time or both would constitute such a material default or breach.
     There is no reason to believe that any of the existing insurance policies
     of JDS and its subsidiaries will not be renewed by the insurer upon the
     scheduled expiry of the policy or will be renewed by the insurer only on
     the basis that there will be a material increase in the premiums payable in
     respect of the policy. True and complete copies of all the existing
     insurance policies of JDS and its subsidiaries have been provided to
     Uniphase.

     3.1.14.  BOOKS AND RECORDS.  The books, records and accounts of JDS and its
     subsidiaries, in all material respects, (i) have been maintained in
     accordance with good business practices on a basis consistent with prior
     years, (ii) are stated in reasonable detail and accurately and fairly
     reflect the transactions and dispositions of the assets of JDS and its
     subsidiaries and (iii) accurately and fairly reflect the basis for the JDS
     consolidated financial statements. JDS has devised and maintains a system
     of internal accounting controls sufficient to provide reasonable assurances
     that (i) transactions are executed in accordance with management's general
     or specific authorization; and (ii) transactions are recorded as necessary
     (A) to permit preparation of financial statements in conformity with
     Canadian generally accepted accounting principles or any other criteria
     applicable to such statements and (B) to maintain accountability for
     assets.

     3.1.15.  LITIGATION, ETC.  There is no claim, action, proceeding or
     investigation pending or, to the knowledge of JDS, threatened against or
     relating to JDS or any of its subsidiaries affecting any of their
     properties, licenses or assets before any court or Governmental Entity or
     regulatory authority or body that, if adversely determined, could
     reasonably be expected to have a Material Adverse Effect, or prevent or
     delay consummation of the transactions contemplated by this Agreement or
     the Arrangement, nor is JDS aware of any basis for any such claim, action,
     proceeding or investigation. Neither JDS nor any of its subsidiaries, nor
     their respective assets and properties, is subject to any outstanding
     judgment, order, writ, injunction or decree that has had or is reasonably
     likely to have a Material Adverse Effect, that involves or may involve, or
     restricts or may restrict, or requires or may require, the expenditure of a
     material amount of money as a condition to or a necessity for the right or
     ability of JDS or any of its material subsidiaries, as the case may be, to
     conduct its business in any manner in which it has been carried on prior to
     January 28, 1999, or prevent or delay consummation of the transactions
     contemplated by this Agreement or the Arrangement.

     3.1.16.  ENVIRONMENTAL.  All operations of JDS and its subsidiaries have
     been conducted, and are now, in compliance with all Environmental Laws.
     Except as JDS has publicly disclosed in documents filed with the OSC since
     January 1, 1998, JDS is not aware that it or any subsidiary is subject to:

           3.1.16.1. any governmental or regulatory remedial or control action,
           proceeding, application, order or directive which relates to
           environmental, health or safety matters or any investigation or
           evaluation concerning environmental, health or safety matters; or

           3.1.16.2. any demand or notice with respect to the breach of, or
           liability under, any Environmental Laws and JDS is not aware of facts
           or circumstances that could reasonably be expected to result in any
           such action, proceeding, application, order, directive, demand, or
           notice to which it or any subsidiary would be subject.

     3.1.17. ZONING AND OTHER MATTERS RELATING TO REAL PROPERTY.

           3.1.17.1. The buildings and other structures located on the real
           property owned or leased by JDS or its subsidiaries (the "JDS
           Property") and the operation and maintenance thereof, as now operated
           and maintained, comply in all material respects with all applicable
           Laws, municipal or otherwise; none of such buildings or other
           structures encroaches upon any land not owned or leased by JDS or its
           subsidiaries; and there are no restrictive covenants, municipal
           by-laws or other Laws which in any way restrict or prohibit the use
           of the JDS Property or such buildings or structures for the purposes
           for which they are presently being used.

           3.1.17.2. There are no expropriation or similar proceedings, actual
           or threatened, of which JDS or its subsidiaries has received notice
           against any of the JDS Property or any part thereof.

                                      A-20

           3.1.17.3. No buildings or other structures located on the JDS
           Property contain any friable asbestos or any other substance
           containing asbestos and deemed hazardous by any Environmental Laws
           applicable to JDS or its subsidiaries.

     3.1.18.  NO CONTAMINANTS.  The JDS Property has not been and is not now
     used as a landfill or waste disposal site, nor to the knowledge of JDS, has
     any hazardous substance or contaminant been deposited in or disposed of on,
     in, under, or at, the JDS Property, nor, to the knowledge of JDS, has there
     been any release, spill, emission or discharge of any contaminant at the
     JDS Property which would give rise to any action or claim by a third party
     or a Governmental Entity relating to violation of or any liability under
     any such Environmental Laws or other requirements.

     3.1.19. TAX MATTERS.

           3.1.19.1. JDS and each of its subsidiaries have timely filed, or
           caused to be filed, all Tax Returns required to be filed by them (all
           of which returns were correct and complete in all material respects)
           and have paid, or caused to be paid, all Taxes that are due and
           payable and JDS has provided adequate accruals in accordance with
           generally accepted accounting principles in its most recently
           published financial statements for any Taxes for the period covered
           by such financial statements that have not been paid, whether or not
           shown as being due on any Tax Returns. JDS and each of its
           subsidiaries have made adequate provision in their respective books
           and records for any Taxes accruing in respect of any period
           subsequent to the period covered by such financial statements. Since
           such publication date, no material Tax liability not reflected in
           such statements or otherwise provided for has been assessed, proposed
           to be assessed, incurred or accrued other than in the ordinary course
           of business. JDS and its subsidiaries have withheld from all payments
           made by them, or otherwise collected, all material amounts in respect
           of Taxes required to be withheld therefrom or collected by them, and
           have remitted same to the applicable Governmental Entity within the
           required time periods. Neither JDS nor any of its subsidiaries has
           any liability for the Taxes of any other Person.

           3.1.19.2. Neither JDS nor any subsidiary has received any written
           notification that any material issues have been raised (and are
           currently pending) by Revenue Canada, the United States Internal
           Revenue Service or any other taxing authority, including, without
           limitation, any sales tax authority, in connection with any of the
           Tax Returns referred to above, and, no waivers of statutes of
           limitations have been given or requested with respect to JDS or any
           subsidiary. All Tax liability of JDS and its subsidiaries has been
           assessed for all fiscal years up to and including the fiscal year
           ended May 31, 1998. To the best of the knowledge of JDS, there are no
           material proposed (but unassessed) additional Taxes and none has been
           asserted. No Tax liens have been filed other than for Taxes not yet
           due and payable.

     3.1.20. NON-ARMS LENGTH TRANSACTIONS.

           3.1.20.1. None of JDS or its subsidiaries has made any payment or
           loan to, or has borrowed any monies from or is otherwise indebted to,
           any officer, director, employee or shareholder of such company or any
           Person not dealing with it at arm's length (within the meaning of the
           INCOME TAX ACT (Canada)) or any affiliate of any of the foregoing,
           except as disclosed in the Financial Statements or in the JDS
           Disclosure Letter and except for usual compensation paid in the
           ordinary course of business consistent with past practice.

           3.1.20.2. Except as disclosed in the JDS Disclosure Letter and except
           for Contracts made solely between JDS and its subsidiaries and except
           for contracts of employment, none of JDS or its subsidiaries is a
           party to any Contract with any officer, director, employee or
           shareholder of such company or any Person not dealing with it at
           arm's length (within the meaning of the INCOME TAX ACT (Canada)) or
           any affiliate of any of the foregoing.

     3.1.21.  EMPLOYEES.  The JDS Disclosure Letter lists all employees employed
     by, and all individuals engaged on a contractual basis to provide
     employment or sales services to JDS or any of its subsidiaries as at
     January 28, 1999 (the "JDS Employees"). For each of the ten most highly
     compensated JDS Employees, the JDS Disclosure Letter lists such employee's
     date of hire, title or classification, rate of salary,

                                      A-21

     retention, bonus or confidentiality or any consulting Contracts with any
     JDS Employee or former employee of JDS or any of its subsidiaries, as to

           non-officer JDS Employee in excess of $40,000 (Cdn.), and each loan
           to an officer or director of JDS (the "JDS Employee Plans").

           3.1.22.2. All of the JDS Employee Plans are registered where required
           by, and are in good standing under, all applicable Laws or other
           legislative, administrative or judicial promulgations applicable to
           the JDS Employee Plans and there are no actions, claims, proceedings
           or governmental audits pending (other than routine claims for
           benefits) relating to JDS.

           3.1.22.3. All of the JDS Employee Plans have been administered and
           funded in material compliance with their terms and all applicable
           Laws or other legislative, administrative or judicial promulgations
           applicable to the JDS Employee Plans and there are no unfunded
           liabilities in respect of the JDS Employee Plans and all required
           contributions thereunder have been made in accordance with all
           applicable Laws or other legislative, administrative or judicial
           promulgations applicable to the JDS Employee Plans and the terms of
           such JDS Employee Plan.

           3.1.22.4. No amendments to any JDS Employee Plan have been promised
           and no amendments to any JDS Employee Plan will be made or promised
           prior to the Effective Date which affect or pertain to the JDS
           Employees.

           3.1.22.5. True and complete copies of all the JDS Employee Plans as
           amended as of January 28, 1999 and, if available, current plan
           summaries and employee booklets in respect thereof as are applicable
           to the JDS Employees and all related documents or, where oral,
           written summaries of the terms thereof, have been made available to

           3.1.22.7. The assets of each JDS Employee Plan which is a registered
           pension plan are at least equal to the liabilities, contingent or

           subsidiaries. Uniphase has disclosed in the Uniphase Disclosure

           consolidated basis other than the Material Subsidiaries; for the
           purposes hereof, a subsidiary and its subsidiaries shall be
           considered material in relation to Uniphase if (i) the investments in
           and advances to the subsidiary and its subsidiaries by Uniphase and
           its other subsidiaries exceed five percent of the total assets of
           Uniphase and its subsidiaries on a consolidated basis as at June 30,

           extraordinary items of the subsidiary and its subsidiaries exceeds
           five percent of such income of Uniphase and its subsidiaries on a
           consolidated basis for Uniphase's fiscal year ended June 30, 1998.

           ownership interest in any other Person, which interest is material in

     3.2.2.  CAPITALIZATION.

           3.2.2.1.  The authorized capital of Uniphase consists of 1,000,000

           issued and outstanding and 9,367,050 Uniphase Common Shares were
           reserved, in the aggregate, for issuance in respect of the Uniphase

           Except as described in the immediately preceding sentence and except
           pursuant to the Uniphase Rights Agreement, there are no options,
           warrants, conversion privileges or other rights, agreements,
           arrangements or commitments (pre-emptive, contingent or otherwise)
           obligating Uniphase or any of its subsidiaries to issue or sell any
           shares of Uniphase or any of its subsidiaries or securities or

     occurrence, or use of data consisting of, such dates; (b) any failure of
     computer hardware or software products or technology to calculate any
     information dependent on or relating to dates on or after January 28, 1999
     in the same manner, and with the same functionality, data integrity and
     performance, as such computer hardware or software products or technology
     records, stores, processes, calculates and presents calendar dates on or
     before January 28, 1999, or information dependent on or relating to such
     dates; or (c) any loss of functionality or performance with respect to the
     introduction of records or processing of data containing dates falling on
     or after January 28, 1999.

     3.2.7.  SEC REPORTS.

           3.2.7.1.  Uniphase has furnished or made available to JDS true and
           complete copies of each statement, report, registration statement
           (including any prospectus filed pursuant to Rule 424(b) of the 1933
           Act), proxy statement and other filing filed with the SEC by Uniphase
           since March 1, 1996, and, prior to the Effective Time, Uniphase will
           have furnished JDS with true and complete copies of any additional
           documents filed with the SEC by Uniphase prior to the Effective Time
           (such statements, reports, registration statements, prospectuses,
           proxy statements and other filings, including schedules included
           therein, are referred to as the "Uniphase Documents").

           3.2.7.2.  In addition, Uniphase has made available to JDS all
           exhibits to the Uniphase Documents filed prior to January 28, 1999,
           and will promptly make available to JDS all exhibits to any
           additional Uniphase Documents filed prior to the Effective Time. All
           documents required to be filed as exhibits to the Uniphase Documents
           have been so filed, and all material contracts so filed as exhibits
           are in full force and effect, except those which have expired in
           accordance with their terms, and neither Uniphase nor any of its
           subsidiaries is in default thereunder.

           3.2.7.3.  The Uniphase Documents are all statements, reports,
           registration statements, and other filings required to be filed by it
           with the SEC since March 1, 1996 and as of their respective filing
           dates, the Uniphase Documents complied in all material respects with
           the requirements of the 1934 Act, the 1933 Act and the rules and
           regulations promulgated thereunder, and none of the Uniphase
           Documents contained any untrue statement of a material fact or
           omitted to state a material fact required to be stated therein or
           necessary to make the statements made therein, in light of the
           circumstances in which they were made, not misleading, except to the
           extent corrected by a subsequently filed Uniphase Document.

                                      A-27

           3.2.7.4.  Uniphase has publicly disclosed in the Uniphase Documents
           any information regarding any event, circumstance or action taken or
           failed to be taken by Uniphase or its subsidiaries which could
           individually or in the aggregate reasonably be expected to have a
           Material Adverse Effect.

     3.2.8.   FINANCIAL STATEMENTS.  The financial statements of Uniphase,
     including the notes thereto, included in the Uniphase Documents (the
     "Uniphase Financial Statements") complied as to form in all material
     respects with applicable accounting requirements and with the published
     rules and regulations of applicable Governmental Entities and the SEC with
     respect thereto as of their respective dates, and have been prepared in
     accordance with United States generally accepted accounting principles
     applied on a basis consistent throughout the periods indicated and
     consistent with each other (except as may be indicated in the notes thereto
     or, in the case of unaudited statements included in quarterly reports on
     Form 10-Q, as permitted by Form 10-Q of the SEC). The Uniphase Financial
     Statements present fairly the consolidated financial position and results
     of operations of Uniphase and its subsidiaries at the dates and during the
     periods indicated therein (subject, in the case of unaudited statements, to
     normal, recurring year-end adjustments and the absence of notes thereto)
     and reflect appropriate and adequate reserves in respect of contingent
     liabilities, if any, of Uniphase and its subsidiaries on a consolidated
     basis. There has been no change in Uniphase accounting policies, except as
     described in the notes to the Uniphase Financial Statements, since June 30,
     1998.

     3.2.9.   ABSENCE OF CERTAIN CHANGES.  Except as disclosed in publicly
     available reports filed by Uniphase with the SEC prior to January 28, 1999,
     since June 30, 1998 (the "Uniphase Balance Sheet Date"), each of the
     Uniphase Parties has conducted its business in the ordinary and regular
     course consistent with past practice and there has not occurred:

           3.2.9.1.  any material change in its affairs or in its financial
           condition, business, assets, liabilities, results of operations or
           prospects;

           3.2.9.2.  any acquisition, sale or transfer of any material asset of
           Uniphase or any of its subsidiaries other than in the ordinary course
           of business and consistent with past practice;

           3.2.9.3.  any change in accounting methods or practices (including
           any change in depreciation or amortization policies or rates, or
           capitalized software policies) by Uniphase or any revaluation by
           Uniphase of any of its or any of its subsidiaries' assets;

           3.2.9.4.  any declaration, setting aside, or payment of a dividend or
           other distribution with respect to the shares of Uniphase, or any
           direct or indirect redemption, purchase or other acquisition by
           Uniphase of any of its shares of capital stock;

           3.2.9.5.  any material contract entered into by Uniphase or any of
           its subsidiaries, other than in the ordinary course of business, or
           any material amendment or termination of, or default under, any
           material contract to which Uniphase or any of its subsidiaries is a
           party or by which it is bound;

           3.2.9.6.  any agreement by Uniphase or any of its subsidiaries to do
           any of the things described in the preceding clauses 3.2.9.1 through
           3.2.9.5 (other than negotiations with JDS and its representatives
           regarding the transactions contemplated by this Agreement); or

           3.2.9.7.  any agreement or arrangement to take any action which, if
           taken prior to January 28, 1999, would have made any representation
           or warranty set forth in this Agreement materially untrue or
           incorrect as of the date when made.

     3.2.10.  ABSENCE OF UNDISCLOSED LIABILITIES.  Uniphase has no material
     obligations or liabilities of any nature (matured or unmatured, fixed or
     contingent), other than:

           3.2.10.1. those set forth or adequately provided for in the balance
           sheet included in Uniphase's Annual Report on Form 10-K for the
           period ended June 30, 1998 (the "Uniphase Balance Sheet");

                                      A-28

           3.2.10.2. those incurred in the ordinary course of business and not
           required to be set forth in the Uniphase Balance Sheet under United
           States generally accepted accounting principles;

           3.2.10.3. those incurred in the ordinary course of business since the
           Uniphase Balance Sheet Date and consistent with past practice; and

           3.2.10.4. those incurred in connection with the execution of this
           Agreement.

     3.2.11.  MATERIAL CONTRACTS.  None of Uniphase, its subsidiaries, nor to
     the knowledge of Uniphase any of the other parties thereto, is in default
     or breach of, in any material respect, nor has Uniphase or its subsidiaries
     received any notice of material default or termination under, any Material
     Contract and, to the knowledge of Uniphase, there exists no state of facts
     which after notice or lapse of time or both would constitute such a
     material default or breach. Except for the Material Contracts disclosed in
     the Uniphase Disclosure Letter, none of Uniphase nor its subsidiaries is a
     party to any (i) Contract which involves the payment to or by Uniphase or
     its subsidiaries of more than US$5,000,000 during any remaining year of the
     Contract or (ii) Contract not made in the ordinary course of business or
     which creates liabilities or obligations which are not in the ordinary
     course of business. True and complete copies of all Uniphase's Material
     Contracts, or where such Contracts are oral, true and complete written
     summaries of the terms thereof, have been furnished to or made available to
     JDS.

     3.2.12.  CUSTOMERS AND SUPPLIERS.  Since the Uniphase Balance Sheet Date,
     there has been no termination or cancellation of, and no material
     modification or change in, the business relationship with any customer or
     group of customers which singly or in the aggregate provided more than 10%
     of the consolidated gross revenues of Uniphase and its subsidiaries for the
     fiscal year ended on the Uniphase Balance Sheet Date. Uniphase has no
     reason to believe that the benefits of any relationship with any of the
     customers or suppliers of Uniphase and its subsidiaries will not continue
     after the Effective Date in substantially the same manner as prior to
     January 28, 1999, assuming the completion on the Effective Date of the
     Arrangement. Uniphase has furnished or made available to JDS Uniphase's
     standard form product warranty provided to customers and except as set
     forth in the Uniphase Disclosure Letter, no Uniphase product warranty
     relating to a Contract for the sale of goods or services worth more than
     US$500,000 differs from the standard form in any material respect.

     3.2.13.  INSURANCE.  Uniphase has furnished or made available to JDS
     accurate particulars of the policies of insurance maintained by Uniphase
     and its subsidiaries at January 28, 1999, including the name of the
     insurer, the risks insured against and the amount of coverage. All such
     policies are in full force and effect. None of Uniphase or its subsidiaries
     or, to the knowledge of Uniphase, any of the other parties thereto, is in
     default or breach of, whether as to the payment of premiums or otherwise,
     nor has Uniphase or its subsidiaries received any notice of material
     default or termination under, any such policy and, to the knowledge of
     Uniphase, there exists no state of facts which after notice or lapse of
     time or both would constitute such a material default or breach. There is
     no reason to believe that any of the existing insurance policies of
     Uniphase and its subsidiaries will not be renewed by the insurer upon the
     scheduled expiry of the policy or will be renewed by the insurer only on
     the basis that there will be a material increase in the premiums payable in
     respect of the policy. True and complete copies of all the existing
     insurance policies of Uniphase and its subsidiaries have been provided to
     JDS.

     3.2.14.  BOOKS AND RECORDS.  The books, records and accounts of Uniphase
     and its subsidiaries, in all material respects, (i) have been maintained in
     accordance with good business practices on a basis consistent with prior
     years, (ii) are stated in reasonable detail and accurately and fairly
     reflect the transactions and dispositions of the assets of Uniphase and its
     subsidiaries and (iii) accurately and fairly reflect the basis for the
     Uniphase consolidated financial statements. Uniphase has devised and
     maintains a system of internal accounting controls sufficient to provide
     reasonable assurances that (i) transactions are executed in accordance with
     management's general or specific authorization; and (ii) transactions are
     recorded as necessary (A) to permit preparation of financial statements in
     conformity with United States generally accepted accounting principles or
     any other criteria applicable to such statements and (B) to maintain
     accountability for assets.

                                      A-29

     3.2.15.  LITIGATION, ETC.  There is no claim, action, proceeding or
     investigation pending or, to the knowledge of Uniphase, threatened against
     or relating to Uniphase or any of its subsidiaries or affecting any of
     their properties, licenses or assets before any court or Governmental
     Entity or regulatory authority or body that, if adversely determined, could
     reasonably be expected to have a Material Adverse Effect, or prevent or
     delay consummation of the transactions contemplated by this Agreement or
     the Arrangement, nor is Uniphase aware of any basis for any such claim,
     action, proceeding or investigation. Neither Uniphase nor any of its
     subsidiaries, nor their respective assets and properties, is subject to any
     outstanding judgment, order, writ, injunction or decree that has had or is
     reasonably likely to have a Material Adverse Effect, that involves or may
     involve, or restricts or may restrict, or requires or may require, the
     expenditure of a material amount of money as a condition to or a necessity
     for the right or ability of Uniphase or any of its material subsidiaries,
     as the case may be, to conduct its business in any manner in which it has
     been carried on prior to January 28, 1999, or prevent or delay consummation
     of the transactions contemplated by this Agreement or the Arrangement.

     3.2.16.  ENVIRONMENTAL.  All operations of Uniphase and its subsidiaries
     have been conducted, and are now, in compliance with all Environmental
     Laws. Except as Uniphase has publicly disclosed in documents filed with the
     SEC since January 1, 1998, Uniphase is not aware that it or any subsidiary
     is subject to:

           3.2.16.1. any governmental or regulatory remedial or control action,
           proceeding, application, order or directive which relates to
           environmental, health or safety matters or any investigation or
           evaluation concerning environmental, health or safety matters; or

           3.2.16.2. any demand or notice with respect to the breach of, or
           liability under, any Environmental Laws and Uniphase is not aware of
           facts or circumstances that could reasonably be expected to result in
           any such action, proceeding, application, order, directive, demand,
           or notice to which it or any subsidiary would be subject.

     3.2.17. ZONING AND OTHER MATTERS RELATING TO REAL PROPERTY.

           3.2.17.1. The buildings and other structures located on the real
           property owned or leased by Uniphase or its subsidiaries (the
           "Uniphase Property") and the operation and maintenance thereof, as
           now operated and maintained, comply in all material respects with all
           applicable Laws, municipal or otherwise; none of such buildings or
           other structures encroaches upon any land not owned or leased by
           Uniphase or its subsidiaries; and there are no restrictive covenants,
           municipal by-laws or other Laws which in any way restrict or prohibit
           the use of the Uniphase Property, buildings or structures for the
           purposes for which they are presently being used.

           3.2.17.2. There are no expropriation or similar proceedings, actual
           or threatened, of which Uniphase or its subsidiaries has received
           notice against any of the Uniphase Property or any part thereof.

           3.2.17.3. No buildings or other structures located on Uniphase
           Property contain any friable asbestos or any other substance
           containing asbestos and deemed hazardous by any Environmental Laws
           applicable to Uniphase or its subsidiaries.

     3.2.18.  NO CONTAMINANTS.  The Uniphase Property has not been and is not
     now used as a landfill or waste disposal site, nor to the knowledge of
     Uniphase, has any hazardous substance or contaminant been deposited in or
     disposed of on, in, under, or at, the Uniphase Property, nor, to the
     knowledge of Uniphase, has there been any release, spill, emission or
     discharge of any contaminant at the Uniphase Property which would give rise
     to any action or claim by a third party or a Governmental Entity relating
     to violation of or any liability under any such Environmental Laws or other
     requirements.

     3.2.19. TAX MATTERS.

           3.2.19.1. Uniphase and each of its subsidiaries have timely filed, or
           caused to be filed, all Tax Returns required to be filed by them (all
           of which returns were correct and complete in all material respects)
           and have paid, or caused to be paid, all Taxes that are due and
           payable and Uniphase has provided adequate accruals in accordance
           with generally accepted accounting principles in its most recently
           published financial statements for any Taxes for the period covered

                                      A-30

           by such financial statements that have not been paid, whether or not
           shown as being due on any Tax Returns. Uniphase and each of its
           subsidiaries have made adequate provision in their respective books
           and records for any Taxes accruing in respect of any period
           subsequent to the period covered by such financial statements. Since
           such publication date, no material Tax liability not reflected in
           such statements or otherwise provided for has been assessed, proposed
           to be assessed, incurred or accrued other than in the ordinary course
           of business. Uniphase and its subsidiaries have withheld from all
           payments made by them, or otherwise collected, all material amounts
           in respect of Taxes required to be withheld therefrom or collected by
           them and have remitted same to the applicable Governmental Entity
           within the required time periods. Neither Uniphase nor any of its
           subsidiaries has any liability for the Taxes of any other Person.

           3.2.19.2. Neither Uniphase nor any subsidiary has received any
           written notification that any material issues have been raised (and
           are currently pending) by the United States Internal Revenue Service,
           Revenue Canada or any other taxing authority, including, without
           limitation, any sales tax authority, in connection with any of the
           Tax Returns referred to above, and no waivers of statutes of
           limitations have been given or requested with respect to Uniphase or
           any subsidiary. No Tax liens have been filed other than for Taxes not
           yet due and payable. Uniphase is not a party to any tax sharing
           agreement or similar arrangement.

     3.2.20. NON-ARM'S LENGTH TRANSACTIONS.

           3.2.20.1. None of Uniphase or its subsidiaries has made any payment
           or loan to, or has borrowed any monies from or is otherwise indebted
           to, any officer, director, employee or shareholder of such company or
           any Person not dealing with it at arm's length (within the meaning of
           the INCOME TAX ACT (Canada)) or any affiliate of any of the
           foregoing, except as disclosed in the Financial Statements or in the
           Uniphase Disclosure Letter and except for usual compensation paid in
           the ordinary course of business consistent with past practice.

           3.2.20.2. Except as disclosed in the Uniphase Disclosure Letter and
           except for Contracts made solely between Uniphase and its
           subsidiaries and except for contracts of employment, none of Uniphase
           or its subsidiaries is a party to any Contract with any officer,
           director, employee or shareholder of such company or any Person not
           dealing with it at arm's length (within the meaning of the INCOME TAX
           ACT (Canada)) or any affiliate of any of the foregoing.

     3.2.21.  EMPLOYEES.  The Uniphase Disclosure Letter lists all employees
     employed by, and all individuals engaged on a contractual basis to provide
     employment or sales services to Uniphase or any of its subsidiaries as at
     January 28, 1999 (the "Uniphase Employees"). For each of the ten most
     highly compensated Uniphase Employees, the Uniphase Disclosure Letter lists
     such employee's name, date of hire, title or classification, rate of
     salary, commission or bonus entitlements (if any) and any other benefits
     extended to, or circumstances unique to each such employee. Except as
     described in the Uniphase Disclosure Letter, neither Uniphase nor any of
     its subsidiaries is a party to or bound by any Contracts relating to
     employment, severance, retention, bonus or confidentiality or any
     consulting Contracts with any Uniphase Employee or former employee of
     Uniphase or any of its subsidiaries written or otherwise, as to which
     unsatisfied obligations of Uniphase or any of its subsidiaries of greater
     than $75,000 (Cdn.) remain outstanding.

     3.2.22. EMPLOYEE BENEFIT PLANS.

           3.2.22.1. The Uniphase Disclosure Letter lists, with respect to
           Uniphase, any subsidiary of Uniphase and any trade or business
           (whether or not incorporated) which is treated as a single employer
           with Uniphase (an "ERISA Affiliate") within the meaning of Section
           414(b), (c), (m) or (o) of the Internal Revenue Code (the "Code"),
           (i) all material employee benefit plans (as defined in Section 3(3)

           (iii) all bonus, pension, profit sharing, savings, deferred
           compensation or incentive plans, programs or arrangements, (iv) other
           fringe or employee benefit plans, programs or arrangements that apply
           to senior management of Uniphase and that do not generally apply to
           all employees, and (v) any current or former employment or executive
           compensation or severance agreements, written or otherwise, as to
           which unsatisfied obligations of Uniphase of greater than US$50,000
           remain for the benefit of, or relating to, any present or former
           employee, consultant or director of Uniphase or its subsidiaries
           (together, the "Uniphase Employee Plans").

           3.2.22.2. Uniphase has made available or furnished to JDS a copy of
           all documents creating or evidencing all of the Uniphase Employee
           Plans (including trust documents, insurance policies or contracts,
           summary plan descriptions and to the extent still in its possession,
           any material employee communications relating thereto) and has with
           respect to each Uniphase Employee Plan that is subject to the
           reporting and disclosure requirements of Title I of ERISA, provided
           or made available copies of all Forms 5500 required to be filed with
           any government entity for the 1997 plan year and the preceding two
           plan years, if any. Each Uniphase Employee Plan intended to qualify
           under Section 401(a) of the Code has either been determined by the
           Internal Revenue Service to so qualify with respect to the Code, as
           amended by the Tax Reform Act of 1986 and subsequent legislation, or
           has applied to the Internal Revenue Service for such determination
           prior to the expiration of the requisite remedial amendment period
           under applicable Treasury Regulations or official guidance published
           by the Internal Revenue Service. Uniphase has also furnished to JDS
           the most recent Internal Revenue Service determination letter issued
           with respect to each such Uniphase Employee Plan. Nothing has
           occurred since the date of such letter that could reasonably be
           expected to cause the loss of the tax-qualified status of any
           Uniphase Employee Plan subject to Code Section 401(a).

           3.2.22.3. (i) None of the Uniphase Employee Plans promises or
           provides retiree medical or other retiree welfare benefits to any
           person, except as required by the Consolidated Omnibus Budget
           Reconciliation Act of 1985 ("COBRA"); (ii) no "prohibited
           transactions" (as defined in Section 406 or 407 of ERISA or Section
           4975 of the Code) have occurred for which a statutory exemption is
           not available, which could reasonably be expected to have, in the
           aggregate, a Material Adverse Effect; (iii) each Uniphase Employee
           Plan has been administered in accordance with its terms and, to the
           extent applicable, is in compliance with the requirements prescribed
           by any and all statutes, rules and regulations (including ERISA and
           the Code) except as would not have, in the aggregate, a Material
           Adverse Effect, and Uniphase and each subsidiary or ERISA Affiliate
           has performed all obligations required to be performed by it under,
           are not in any respect in default under or violation of, and have no
           knowledge of any default or violation by any other party to, any of
           the Uniphase Employee Plans, which default or violation could
           reasonably be expected to have a Material Adverse Effect, (iv)
           neither Uniphase nor any subsidiary or ERISA Affiliate is subject to
           any liability or penalty under Sections 4976 through 4980 of the Code
           or Title I of ERISA with respect to any of the Uniphase Employee
           Plans which have a Material Adverse Effect on any such parties; (v)
           all material contributions required to be made by Uniphase or any
           subsidiary or ERISA Affiliate to any Uniphase Employee Plan have been
           made on or before their due dates and a reasonable amount has been
           accrued for contributions to each Uniphase Employee Plan for the
           current plan years; (vi) with respect to each Uniphase Employee Plan,
           no "reportable event" within the meaning of section 4043 of ERISA
           (including any such event for which the thirty (30) day notice
           requirement has been waived under the regulations to section 4043 of
           ERISA) nor any event described in Section 4062, 4063 or 4041 of ERISA
           has occurred; and (vii) no Uniphase Employee Plan is covered by, and
           neither Uniphase nor any subsidiary of an ERISA Affiliate has
           incurred or expects to incur any liability under Title IV of ERISA or
           Section 412 of the Code. With respect to each Uniphase Employee Plan
           subject to ERISA as either an employee pension plan within the
           meaning of Section 3(2) of ERISA or an employee welfare benefit plan
           within the meaning of Section 3(1) of ERISA, Uniphase has prepared in
           good faith and timely filed all requisite governmental reports (which
           were true and correct as of the date filed) and has properly and

                                      A-32

           timely filed and distributed or posted all notices and reports to
           employees required to be filed, distributed or posted with respect to
           each such Uniphase Employee Plan. No suit, administrative proceeding,
           action or other litigation has been brought, or to the best knowledge
           of Uniphase is threatened, against or with respect to any such
           Uniphase Employee Plan, including any audit or inquiry by the IRS or
           United States Department of Labor. Neither Uniphase nor any Uniphase
           subsidiary or other ERISA Affiliate is a party to, or has made any
           contribution to or otherwise incurred any obligation under, any
           "multiemployer plan" as defined in Section 3(37) of ERISA.

           3.2.22.4. With respect to each Uniphase Employee Plan, Uniphase and
           each of its United States subsidiaries have complied with (i) the
           applicable health care continuation and notice provisions of the
           COBRA and the proposed regulations thereunder and (ii) the applicable
           requirements of (A) the Family Leave Act of 1993 and the regulations
           thereunder, and (B) comparable provisions of state law and the
           regulations thereunder, except to the extent that such failure to
           comply would not, in the aggregate, reasonably be expected to have a
           Material Adverse Effect.

           3.2.22.5. There has been no amendment to, written interpretation or
           announcement (whether or not written) by Uniphase, any Uniphase
           subsidiary or other ERISA Affiliate relating to, or change in
           participation or coverage under, any Uniphase Employee Plan which
           would materially increase the expense of maintaining such Plan above
           the level of expense incurred with respect to that Plan for the most
           recent fiscal year included in Uniphase's financial statements.

     3.2.23.  LABOUR MATTERS.  Neither Uniphase or any of its subsidiaries is
     bound by or a party to any collective bargaining Contracts with any trade
     union, counsel of trade unions, employee bargaining agent or affiliated
     bargaining agent (collectively, "labour representatives"), and neither
     Uniphase nor any of its subsidiaries has conducted any negotiations with
     respect to any such future Contracts; no labour representatives hold
     bargaining rights with respect to any Uniphase Employees; no labour
     representatives have applied to have Uniphase or any of its subsidiaries
     declared a related employer; there are no current or threatened attempts to
     organize or establish any trade union or employee association with respect
     to Uniphase or any of its subsidiaries; there is no strike, dispute,
     slowdown, lockout, shutdown, work stoppage, unresolved material labour
     union grievance, labour arbitration, unfair labour practice, successor
     rights or common employer proceeding or other concerted action or formal
     grievance existing against Uniphase or any of its subsidiaries.

     3.2.24.  CIRCULARS.  The information relating to Uniphase, Exchangeco and
     Uniphase's subsidiaries to be contained in the Uniphase Circular, the JDS
     Circular or any amendment thereto (including any information referred to
     therein or incorporated therein by reference) will be accurate and complete
     in all material respects as of the date thereof, on the date each such
     circular is first mailed to JDS' or Uniphase's shareholders and at the time

     misleading; or omit to state any material fact necessary to correct any
     statement in any earlier communication with respect to the solicitation of
     proxies for the Meetings which has become false or misleading.

     complied with and are not in violation of any applicable Laws, orders,
     judgments and decrees. Without limiting the generality of the foregoing,
     all securities of Uniphase (including, without limitation, all options,
     rights or other convertible or exchangeable securities) have been issued in
     compliance with all applicable securities Laws and all securities to be
     issued upon exercise of any such options, rights and other convertible or
     exchangeable securities will be issued in compliance with all applicable
     securities Laws.

     3.2.26.  RESTRICTIONS ON BUSINESS ACTIVITIES.  There is no agreement,
     judgment, injunction, order or decree binding upon Uniphase or any Material
     Subsidiary that has or could reasonably be expected to have the effect of
     prohibiting, restricting or materially impairing any business practice of
     Uniphase or any Material Subsidiary, any acquisition of property by
     Uniphase or any Material Subsidiary or the conduct of business by Uniphase
     or any Material Subsidiary as currently conducted.

     order to consummate and make effective, as soon as reasonably practicable,
     the transactions contemplated in this Agreement and, without limiting the

                                      A-37

           5.3.7.8.  subject to section 5.6 hereof and applicable Laws, shall
           make and cooperate in the making of all filings and applications and
           submissions of information under all Laws which are applicable in
           connection with the transactions contemplated herein and take all
           reasonable actions in connection therewith, including without
           limitation, in connection with the Appropriate Regulatory Approvals
           and by participating and appearing in any proceedings of either party
           before Governmental Entities, and use its reasonable best efforts to

           to the accuracy of its representations and warranties contained in
           section 6.2 or section 6.3, as applicable and (b) ensure that its
           representations and warranties remain accurate until the Effective
           Date; and

     issuance upon the Arrangement and the exchange from time to time of the
     Exchangeable Shares and upon the exercise from time to time of the
     Replacement Options.

5.4.  COVENANTS REGARDING NON-SOLICITATION

     5.4.1.   Neither JDS nor Uniphase shall, directly or indirectly, through
     any officer, director, employee, representative, financial advisor or agent
     of JDS or Uniphase, as the case may be, or any of its subsidiaries, (i)
     solicit, initiate or knowingly encourage (including by way of furnishing
     information or entering into any form of agreement, arrangement or
     understanding) the initiation of any Acquisition Proposal or inquiries or
     proposals in connection therewith, (ii) participate in any discussions or
     negotiations regarding any Acquisition Proposal, (iii) withdraw or modify
     the approval of the Board of Directors of JDS or Uniphase, as the case may
     be, of the transactions contemplated hereby in a manner adverse to the
     other, (iv) approve or recommend any Acquisition Proposal or (v) cause JDS
     or Uniphase, as the case may be, to enter into any agreement related to any
     Acquisition Proposal; provided, however, that, subject to section 5.5, but
     notwithstanding the preceding part of this section 5.4.1 and any other
     provision of this Agreement, nothing shall prevent the Board of Directors
     of JDS or Uniphase from considering, negotiating, approving, recommending
     to its shareholders or entering into an agreement in respect of an
     unsolicited BONA FIDE written Acquisition Proposal (x) that the Board of
     Directors of JDS or Uniphase determines in good faith, after consultation
     with financial advisors and after receiving a written opinion of outside
     counsel to the effect that it is appropriate that the Board of Directors of
     JDS or Uniphase take such action in order to discharge properly its
     fiduciary duties, would reasonably be expected to, if consummated in
     accordance with its terms, result in a transaction more favorable to its
     shareholders than the transaction contemplated by this Agreement and (y)
     that is received prior to the date that its shareholders have approved the
     Arrangement or the Uniphase Proposal, as the case may be (any such
     Acquisition Proposal being referred to herein as a "Superior Proposal").

     5.4.2.   Each of JDS and Uniphase shall promptly notify the other party, at
     first orally and then in writing, of all current Acquisition Proposals, and
     of all future Acquisition Proposals, of which its directors or senior
     officers are or become aware, or any amendments to the foregoing, or any
     request for non-public information relating to JDS or Uniphase, as the case
     may be, or any of their subsidiaries in connection with an Acquisition
     Proposal or for access to the properties, books or records of such party or
     any subsidiary by any Person that informs such party or such subsidiary
     that it is considering making, or has made, an Acquisition Proposal. Such
     notice shall include a description of the material terms and

                                      A-38

     conditions of any proposal and provide such details of the proposal,
     inquiry or contact as Uniphase or JDS, as the case may be, may reasonably
     request including the identity of the Person making such proposal, inquiry
     or contact.

     5.4.3.   If JDS or Uniphase receives a request for material non-public
     information from a Person who proposes a BONA FIDE Acquisition Proposal in
     respect of JDS or Uniphase (the existence and content of which have been
     disclosed to the other party), and the Board of Directors of such party
     determines that such proposal would be likely to be a Superior Proposal
     pursuant to section 5.4.1 having received the advice referred to therein,
     then, and only in such case, the Board of Directors may, subject to the
     execution by such Person of a non-disclosure agreement containing a
     standstill provision substantially similar to that contained in section
     5.7, provide such Person with access to information regarding the party and
     its subsidiaries; provided, however, that the Person making the Acquisition
     Proposal shall not be precluded under such non-disclosure agreement from
     making the Acquisition Proposal, and provided further that such party sends
     a copy of any such non-disclosure agreement to the other party immediately
     upon its execution and the other party is provided with a list of or copies
     of the information provided to such Person and immediately provided with
     access to similar information to which such Person was provided.

     5.4.4.   Each party hereto shall ensure that its officers, directors and
     employees and its subsidiaries and their officers, directors and employees
     and any financial advisors or other advisors or representatives retained by
     it are aware of the provisions of this section 5.4, and, for greater
     certainty, it shall be responsible for any breach of this section 5.4 by
     its financial advisors or other advisors or representatives.

5.5.  NOTICE OF SUPERIOR PROPOSAL DETERMINATION

     5.5.1.   Each of JDS and Uniphase shall not accept, approve, recommend or
     enter into any agreement in respect of an Acquisition Proposal (other than
     a non-disclosure agreement contemplated by section 5.4.3) on the basis that
     it would constitute a Superior Proposal unless (i) it has provided the
     other party with a copy of the Acquisition Proposal document which the
     Board of Directors of the recipient of the Acquisition Proposal (the
     "Recipient") has determined would be a Superior Proposal, and (ii) five
     Business Days shall have elapsed from the later of the date the other party
     received notice of the Recipient's proposed determination to accept,
     approve, recommend or enter into an agreement in respect of such
     Acquisition Proposal, and the date the other party received a copy of the
     Acquisition Proposal. Information provided under this section 5.5.1 shall
     constitute Information for purposes of section 5.6.2.

     5.5.2.   During such five Business Day period, the Recipient acknowledges
     that the other party shall have the opportunity, but not the obligation, to
     offer to amend the terms of this Agreement and the Arrangement. The Board
     of Directors of the Recipient will review any offer by the other party to
     amend the terms of this Agreement in good faith in order to determine, in
     its discretion in the exercise of its fiduciary duties, whether the other
     party's offer upon acceptance by the Recipient would result in the
     Acquisition Proposal not being a Superior Proposal. If the Board of
     Directors of the Recipient so determines, it will enter into an amended
     agreement with the other party reflecting the amended proposal. If the
     Board of Directors of the Recipient continues to believe, in good faith and
     after consultation with financial advisors and outside counsel, that the
     Acquisition Proposal is nonetheless a Superior Proposal and therefore
     rejects the amended proposal, the Recipient will pay to the other party the
     compensation payable to the other party under Article 9.

     5.5.3.   JDS and Uniphase also acknowledge and agree that each successive
     modification of any Acquisition Proposal shall constitute a new Acquisition
     Proposal for purposes of the requirement under clause (ii) of section 5.5.1
     to initiate an additional five Business Day notice period.

5.6.  ACCESS TO INFORMATION

     5.6.1.   Subject to sections 5.6.2 to and including 5.6.11 and applicable
     Laws, upon reasonable notice, each of JDS and Uniphase shall (and shall
     cause each of its subsidiaries to) afford the Representatives of the other
     party hereto access, during normal business hours from January 28, 1999 and
     until the earlier of the Effective Date or the termination of this
     Agreement, to its properties, books, contracts and records as

                                      A-39

     well as to its management personnel, and, during such period, each party
     shall (and shall cause each of its subsidiaries to) furnish promptly to the
     other party all information concerning its business, properties and
     personnel as such party may reasonably request.

     5.6.2.   The Information will be kept strictly confidential and shall not,
     without the prior written consent of the Disclosing Party, be disclosed by
     the Receiving Party, or by its Representatives, in any manner whatsoever,
     in whole or in part, and shall not be used by the Receiving Party or its
     Representatives other than in connection with the Arrangement. Moreover,
     the Receiving Party agrees to reveal the Information only to its
     Representatives who have a reasonable need to know the Information for the
     purposes of evaluating the Arrangement, who are informed by the Receiving
     Party of the confidential nature of the Information and who have agreed to
     act in accordance with the terms and conditions of this Agreement.
     Notwithstanding such agreement, the Receiving Party shall continue to be
     responsible for any breach of this Agreement by its Representatives and
     shall indemnify and save the Disclosing Party harmless from any breach by
     any of the Receiving Party's Representatives.

     5.6.3.   The Receiving Party shall keep a record of the Information
     furnished to it, in any medium other than oral, and the location of such
     Information. All copies of the Information, except for that portion of the
     Information which consists of analyses, compilations, forecasts, studies or
     other documents prepared by the Receiving Party or its Representatives will
     be returned to the Disclosing Party immediately upon its request. That
     portion of the Information which consists of analyses, compilations,
     forecasts, studies or other documents prepared by the Receiving Party or
     its Representatives, will be destroyed upon the Disclosing Party's request
     and any oral Information will continue to be subject to the terms of this
     Agreement. Upon the request of the Disclosing Party, the Receiving Party
     shall provide a certificate certifying as to the complete return and
     destruction of all Information in accordance with the terms of this
     paragraph.

     5.6.4.   The Receiving Party shall keep all of the Information disclosed or
     delivered to it, whether electronically stored or in a tangible form,
     segregated from all of its property and in a safe and secure environment
     and will protect and keep safe all of the Information disclosed from any
     loss, harm, theft, unauthorized use, tampering, sabotage, unauthorized
     duplication, destruction, addition, deletion, damage or interference
     whatsoever.

     5.6.5.   The Receiving Party acknowledges that the Information is
     confidential and a valuable asset of the Disclosing Party and all right,
     title and interest in and to the Information (including all Intellectual
     Property) is and at all time shall remain the exclusive property of the
     Disclosing Party.

     5.6.6.   The Receiving Party acknowledges that other than as contained in
     this Agreement none of the Disclosing Party, its Representatives or any of
     its or their respective affiliates makes any express or implied
     representation or warranty as to the accuracy or completeness of the
     Information.

     5.6.7.   If the Receiving Party or anyone to whom the Receiving Party
     transmits the Information pursuant to this Agreement becomes legally
     compelled to disclose any of the Information, the Receiving Party will
     provide the Disclosing Party with prompt notice so that the Disclosing
     Party may seek a protective order or other appropriate remedy and/or waive
     compliance with the provisions of this Agreement. If such protective order
     or other remedy is not obtained or the Disclosing Party waives compliance
     with the provisions of this Agreement, the Receiving Party will furnish
     only that portion of the Information which it is advised, by written
     opinion of counsel, addressed to the Receiving Party and to the Disclosing
     Party, is legally required and will exercise its best efforts to obtain
     reliable assurance that confidential treatment will be accorded the
     Information.

     5.6.8.   Without the prior written consent of the Disclosing Party until
     the earlier of the Effective Time and December 31, 2000, neither the
     Receiving Party nor any of its affiliates will, directly or indirectly,
     solicit for employment any person who is then employed or who, within the
     90 day period prior to the date of such solicitation, was employed (either
     as an employee or a consultant) by the Disclosing Party.

     5.6.9.   The Parties each acknowledge that disclosure of any Information
     may cause significant damage and harm to a Disclosing Party, its
     affiliates, subsidiaries and shareholders and that remedies at law may be
     inadequate to protect against breach of this Agreement, and the parties
     hereby in advance agree to the

                                      A-40

     granting of injunctive relief in favour of the Disclosing Party without
     proof of actual damages, in addition to any other remedy the Disclosing
     Party may be entitled to.

     5.6.10.  The parties acknowledge that certain information may be
     competitively sensitive and that disclosure thereof shall be limited to
     that which is reasonably necessary for the purpose of (i) preparing
     submissions or applications in order to obtain the Appropriate Regulatory
     Approvals, (ii) preparing the JDS Circular and the Uniphase Circular, (iii)
     avoiding conflicts and (iv) integrating the operations of Uniphase and JDS.

     5.6.11.  The provisions of sections 5.6.2 to and including 5.6.9 and this
     section 5.6.11 shall survive the termination of this Agreement.

5.7.  MUTUAL STANDSTILL

     During the period commencing on January 28, 1999 and continuing until the
Effective Date or the termination of this Agreement, each of Uniphase and JDS
agrees that it will not, otherwise than pursuant to this Agreement (including

contemplated hereby and thereby or with the prior approval of the other, which
approval may be given on such terms as the other may determine:

     and Uniphase acknowledges that JDS and its agents and advisors (including
     CIBC Wood Gundy Securities Inc.) will be entitled to solicit proxies and

     will be entitled to solicit proxies and otherwise influence any person to

     other;

     5.7.5.   make any public or private disclosure of any consideration,
     intention, plan or arrangement inconsistent with any of the foregoing; or

     5.7.6.   advise, assist or encourage any of the foregoing or work in
     concert with others in respect of the foregoing.

For the purpose of this section 5.7, each reference to Uniphase or JDS shall
include its subsidiaries and its successors. The termination of this Agreement
shall also terminate any other agreements between the parties which have an
effect similar to this section 5.7.

5.8.  CLOSING MATTERS

5.9.  INDEMNIFICATION

     5.9.1.   Uniphase agrees that all rights to indemnification or exculpation
     now existing in favor of the directors or officers of JDS or any subsidiary

     has been provided to Uniphase prior to January 28, 1999, in effect on
     January 28, 1999 shall survive the Arrangement and shall continue in full
     force and effect for a period of not less than six years from the Effective
     Time and Uniphase hereby assumes, effective upon consummation of the
     Arrangement, all such liability with respect to any matters arising prior
     to the Effective Time.

     5.9.2.   There shall be maintained in effect, for not less than six years
     from the Effective Time, coverage equivalent to that in effect under the

     maintained by JDS which is no less advantageous, and with no gaps or lapses
     in coverages with respect to matters occurring prior to the Effective Time.

5.10. EXECUTIVE EMPLOYMENT AGREEMENTS

     5.10.1.  Uniphase agrees that it will offer to retain those JDS Employees

     (other than an appeal made in connection with the Arrangement) of a
     judicial or administrative nature or otherwise, in progress or threatened
     that relates to or results from the transactions contemplated by this
     Agreement that would, if successful, result in an order or ruling that

     obtained;

     6.1.6.   this Agreement shall not have been terminated pursuant to Article

     notice of issuance.

6.2.  UNIPHASE PARTIES CONDITIONS

     The obligations of the Uniphase Parties to complete the transactions
contemplated by this Agreement shall also be subject to the fulfilment of each
of the following conditions precedent (each of which is for the Uniphase
Parties' exclusive benefit and may be waived by Uniphase on behalf of the

relieve the Uniphase Parties of any obligation under this Agreement):

     before the Effective Date shall have been duly performed by JDS in all
     material respects;

     as of an earlier date, in which event such representations and warranties
     which are qualified by materiality shall be true and correct and all other
     representations and warranties shall be true and correct in all material
     respects, in each case, as of such earlier date, or except as affected by
     transactions contemplated or permitted by this Agreement) and the Uniphase

     affirmative recommendation that the holders of the JDS Common Shares
     approve the Arrangement;

     6.2.6.   the Appropriate Regulatory Approvals shall have been obtained in

     The Uniphase Parties may not rely on the failure to satisfy any of the
above conditions precedent as a basis for non-compliance by the Uniphase Parties
with their obligations under this Agreement if the condition precedent would
have been satisfied but for a material default by the Uniphase Parties in
complying with their obligations hereunder.

                                      A-43

6.3.  JDS CONDITIONS

which is for the exclusive benefit of JDS and may be waived by JDS and any one
or more of which, if not satisfied or waived, will relieve JDS of any obligation
under this Agreement):

     6.3.1.   all covenants of the Uniphase Parties under this Agreement to be
     performed on or before the Effective Date shall have been duly performed by
     the Uniphase Parties in all material respects;

     6.3.2.   all representations and warranties of the Uniphase Parties under
     this Agreement which are qualified by materiality shall be true and correct
     and all other representations and warranties shall be true and correct in
     all material respects as of the Effective Date, in each case, as if made on
     and as of such date (except to the extent such representations and
     warranties speak as of an earlier date, in which event such representations
     and warranties which are qualified by materiality shall be true and correct
     and all other representations and warranties shall be true and correct in
     all material respects, in each case, as of such earlier date, or except as
     affected by transactions contemplated or permitted by this Agreement) and
     JDS shall have received a certificate of each of the Uniphase Parties
     addressed to JDS and dated the Effective Date, signed on behalf of each of
     the Uniphase Parties by two senior executive officers of the relevant
     Uniphase Party, confirming the same as at the Effective Date;

     6.3.3.   between January 28, 1999 and the Effective Date, there shall not
     have occurred, in the judgment of JDS, acting reasonably, a Material
     Adverse Change to Uniphase;

     6.3.4.   the Boards of Directors of the Uniphase Parties shall have adopted
     all necessary resolutions, and all other necessary corporate action shall
     have been taken by the Uniphase Parties to permit the consummation of the
     Arrangement and the issue of the Class B Non-Voting Preference Shares and
     the Exchangeable Shares contemplated thereby and the issue of Uniphase
     Common Shares pursuant to the Arrangement and upon the exchange from time
     to time of the Exchangeable Shares and the exercise from time to time of
     the Replacement Options;

     6.3.5.   the Board of Directors of Uniphase shall have made and shall not
     have modified or amended, in any material respect, prior to the Uniphase
     Meeting, an affirmative recommendation that the holders of the Uniphase
     Common Shares approve the Uniphase Proposal;

     6.3.6.   the Appropriate Regulatory Approvals shall have been obtained in
     accordance with Article 4 and shall be in full force and effect and shall
     not be the subject of any stop-order or proceedings seeking a stop-order or
     any revocation proceedings;

     6.3.7.   the Board of Directors of Uniphase shall have granted additional
     options in respect of an aggregate of 4,110,260 Uniphase Common Shares
     effective at the Effective Time to be allocated to those employees of JDS
     designated by the Chief Executive Officer of JDS with the approval of the
     JDS compensation committee. The exercise price for such options shall be
     equal to the closing price of the Uniphase Common Shares on the Nasdaq
     National Market on the Effective Date;

     6.3.8.   The Form S-3 and the Form S-8 shall have been declared effective

     holders of Uniphase Common Shares are entitled to acquire Series B
     Preferred Shares of Uniphase under the Uniphase Rights Agreement; and

     6.3.10.  JDS shall have received confirmation from its counsel, Osler,
     Hoskin & Harcourt, that the tax opinion contained in the JDS Circular
     remains accurate.

     JDS may not rely on the failure to satisfy any of the above conditions
precedent as a basis for non-compliance by JDS with their obligations under this
Agreement if the condition precedent would have been satisfied but for a
material default by JDS in complying with its obligations hereunder.

                                      A-44

6.4.  NOTICE AND CURE PROVISIONS

     6.4.1.   The Uniphase Parties and JDS will give prompt notice to the other
     of the occurrence, or failure to occur, at any time from January 28, 1999
     until the Effective Date, of any event or state of facts which occurrence
     or failure would, or would be likely to:

           6.4.1.1.  cause any of the representations or warranties of the other
           contained herein to be untrue or inaccurate in any material respect
           on the date made or on the Effective Date; or

           6.4.1.2.  result in the failure to comply with or satisfy any

           the other hereunder prior to the Effective Date.

     transactions contemplated hereby pursuant to the conditions precedent
     contained in sections 6.1, 6.2 and 6.3, or exercise any termination right
     arising therefrom, unless forthwith and in any event prior to the filing of
     the Final Order for acceptance by the Director, the Uniphase Parties have
     or JDS has, as the case may be, delivered a written notice to the other
     specifying in reasonable detail all breaches of covenants, representations
     and warranties or other matters which the Uniphase Parties are or JDS is,
     as the case may be, asserting as the basis for the non-fulfillment of the
     applicable condition precedent or the exercise of the termination right, as
     the case may be. If any such notice is delivered, provided that the
     Uniphase Parties are or JDS is, as the case may be, proceeding diligently
     to cure such matter, if such matter is susceptible to being cured, the
     other may not terminate this Agreement until the later of June 30, 1999 and
     the expiration of a period of 30 days from such notice. If such notice has
     been delivered prior to the date of the Meetings, such Meetings shall be
     postponed until the expiry of such period.

6.5.  SATISFACTION OF CONDITIONS

     The conditions precedent set out in sections 6.1, 6.2 and 6.3 shall be
conclusively deemed to have been satisfied, waived or released when, with the
agreement of Uniphase and JDS, a certificate of arrangement in respect of the
Arrangement is issued by the Director.

                                   AMENDMENT

7.1  AMENDMENT

     This Agreement may, at any time and from time to time before or after the
holding of the JDS Meeting but not later than the Effective Date, be amended by
mutual written agreement of the parties hereto, and any such amendment may,
without limitation:

     7.1.1.   change the time for performance of any of the obligations or acts
     of the parties;

     contained and waive or modify performance of any of the obligations of the
     parties; and

     7.1.4.   waive compliance with or modify any conditions precedent herein
     contained;

provided, however, that any such change, waiver or modification does not
invalidate any required security holder approval of the Arrangement.

7.2.  MUTUAL UNDERSTANDING REGARDING AMENDMENTS

     7.2.1.   The parties will continue, from and after January 28, 1999 and
     through and including the Effective Date, to use their respective
     reasonable efforts to maximize present and future financial and tax
     planning opportunities for the shareholders of JDS, and for Uniphase and
     for JDS as and to the extent that the same shall not prejudice any party or
     its security holders. The parties will ensure that such planning activities
     do not impede the progress of the Arrangement in any material way.

                                      A-45

     7.2.2.   The parties agree that if the Uniphase Parties or JDS, as the case
     may be, propose any amendment or amendments to this Agreement or to the
     Plan of Arrangement, the other will act reasonably in considering such
     amendment and if the other and its shareholders are not prejudiced by
     reason of any such amendment the other will co-operate in a reasonable
     fashion with the Uniphase Parties or JDS, as the case may be, so that such
     amendment can be effected subject to applicable Laws and the rights of the
     security holders.

           Uniphase's shareholders);

           8.1.3.2.  be terminated by JDS, provided that JDS is not then in
           breach or default of any of its obligations hereunder, upon any
           determination by JDS' Board of Directors at the conclusion of the
           process set out in sections 5.4 and 5.5 that an Acquisition Proposal

           moneys payable to Uniphase under section 9.1;

           8.1.3.3.  be terminated by Uniphase, provided that Uniphase is not

                   that any Acquisition Proposal is a Superior Proposal, or
                   resolved to take any of the foregoing actions,

                   8.1.3.4.2.  the Board of Directors of JDS shall have
                   withdrawn or modified in a manner adverse to the Uniphase
                   Parties the board's approval or recommendation of the
                   Arrangement (other than as a direct result of and in direct
                   response to a material breach by Uniphase of its obligations
                   hereunder or a Material Adverse Change to Uniphase), or

                   8.1.3.4.3.  the holders of the JDS Common Shares shall fail
                   to approve the Arrangement at the JDS Meeting, or

                   8.1.3.4.4.  through the fault (whether by commission or
                   omission) of JDS, the Arrangement is not, prior to July 31,
                   1999, submitted for the approval of the holders of the JDS
                   Common Shares at the JDS Meeting and, for greater certainty,
                   JDS shall not

                                      A-46

                   be at fault if the JDS Resolution is not submitted for the
                   approval of the holders of the JDS Common Shares at the JDS
                   Meeting by reason of the failure of the parties to obtain an
                   Appropriate Regulatory Approval to be obtained on or before
                   the date of the JDS Meeting (other than as a direct result of
                   a material breach by JDS of its obligations hereunder),

           subject to the payment by JDS of the moneys payable to Uniphase under

                   5.5 that any Acquisition Proposal is a Superior Proposal, or
                   resolved to take any of the foregoing actions,

                   8.1.3.5.2.  the Board of Directors of Uniphase shall have
                   withdrawn or modified in a manner adverse to JDS the board's
                   approval or recommendation of the Arrangement (other than as
                   a direct result of and in direct response to a material
                   breach by JDS of its obligations hereunder or a Material
                   Adverse Change to JDS), or resolved to take any of the
                   foregoing actions,

                   8.1.3.5.3.  the holders of the Uniphase Common Shares shall
                   fail to approve the Uniphase Proposal at the Uniphase
                   Meeting, or

                   8.1.3.5.4.  through the fault (whether by commission or
                   omission) of Uniphase, the Uniphase Proposal is not, prior to
                   July 31, 1999, submitted for approval of the holders of the
                   Uniphase Common Shares at the Uniphase Meeting and, for
                   greater certainty, Uniphase shall not be at fault if the
                   Uniphase Proposal is not submitted for the approval of the
                   holders of the Uniphase Common Shares at the Uniphase Meeting
                   by reason of the failure of the parties to obtain an
                   Appropriate Regulatory Approval to be obtained on or before
                   the date of the Uniphase Meeting (other than as a direct
                   result of a material breach by Uniphase of its obligations
                   hereunder),

           subject to the payment by Uniphase of the moneys payable to JDS under
           section 9.2.

     8.1.4.   The Agreement shall automatically terminate upon termination by
     Furukawa of its obligations under the Furukawa Support Agreement pursuant
     to section 2.10 of the Furukawa Support Agreement.

     8.1.5.   If the Effective Date does not occur on or prior to September 30,
     1999, then this Agreement shall terminate, provided that JDS and the
     Uniphase Parties may mutually agree to extend such date.

     8.1.6.   If this Agreement is terminated in accordance with the foregoing
     provisions of this section 8, no party shall have any further liability to
     perform its obligations hereunder except as otherwise contemplated hereby,
     and provided that, subject to section 9.3, neither the termination of this
     Agreement nor anything contained in this section 8.1.6 shall relieve any
     party from any liability for any breach by it of this Agreement, including
     from any inaccuracy in its representations and warranties and any
     non-performance by it of its covenants made herein.

                                   ARTICLE 9.

     shall be a condition precedent to consummating the JDS Transaction.

     9.1.4.   Uniphase shall not be entitled to receive any payment under this

     9.2.2.   If the Agreement is terminated pursuant to section 8.1.2 (solely
     relating to any condition in section 6.3.1 or 6.3.2), 8.1.3.5.3 or

     as payment in full of JDS' out-of-pocket costs and expenses in connection
     with the transactions contemplated by this Agreement, in immediately
     available funds to an account designated by JDS; provided that if, in the
     case of a termination in the case of section 8.1.3.5.3 or 8.1.3.5.4, an
     Acquisition Proposal shall have been made in respect of Uniphase and not
     affirmatively rejected by the Board of Directors at or before the time of
     the Uniphase Meeting, then Uniphase shall pay to JDS an amount equal to
     US$105,000,000, in immediately available funds to an account designated by
     JDS. Such payment shall be due (i) in the case of the termination pursuant

     8.1.3.5.3 or 8.1.3.5.4, an Acquisition Proposal in respect of Uniphase is
     consummated (the "Uniphase Transaction"), then Uniphase shall pay to JDS an
     additional fee of US$105,000,000 less any fees previously paid under
     section 9.2.2 or any damages awarded under this Agreement in immediately
     available funds to an account designated by JDS whether before or
     simultaneously with the consummation of the Uniphase Transaction. Uniphase
     agrees that the payment of the fee to JDS required under this section 9.2.3
     shall be a condition precedent to consummating the Uniphase Transaction.

     9.2.4.   JDS shall not be entitled to receive any payment under this
     section 9.2 if, at the time of delivery of the applicable notice of
     termination pursuant to section 8.1, JDS is in material breach of this
     Agreement or the JDS Meeting has taken place and the JDS shareholders have
     failed to approve the JDS Resolution.

9.3.  LIMITED REMEDY

     9.3.1.   For greater certainty, the parties hereto agree that the
     compensation to be received pursuant to this Article 9 is the sole remedy

     party from seeking injunctive relief to restrain any breach or threatened
     breach of the covenants or agreements set forth in this Agreement
     (including pursuant to section 5.6) or otherwise to obtain specific
     performance of any of such act, covenants or agreements, without the
     necessity of posting bond or security in connection therewith.

                               and

       IN THE MATTER OF AN APPLICATION BY JDS FITEL INC.

       RELATING TO A PROPOSED ARRANGEMENT INVOLVING

       JDS FITEL INC. AND ITS SECURITYHOLDERS

                                 INTERIM ORDER

    THIS MOTION, made by the Applicant JDS FITEL Inc. ("JDS") for an interim

heard this day at Toronto, Ontario.

     ON READING the Affidavit of Leo Lefebvre sworn May 6, 1999 (the

for JDS, and counsel for Uniphase Corporation, no one appearing for the Director
appointed under section 260 of the CBCA (the "Director") although served with

     including the Affidavit and the Exhibits thereto on the Director is valid
     service.

2.   THIS COURT ORDERS that JDS call, hold and conduct a special meeting (the
     "JDS Meeting") of the holders of its common shares (the "Common Shares")
     to, among other things, consider and, if deemed advisable, to pass, with or
     without variation, a special resolution (the "Arrangement Resolution") to
     approve an arrangement (the "Arrangement") substantially in the form set
     forth in the Plan of Arrangement attached as Appendix C of Exhibit "A" to

     or supplements to the Plan of Arrangement as it may determine pursuant to
     the terms of the Plan of Arrangement, and the Plan of Arrangement as so
     amended, revised or supplemented shall be the Plan of Arrangement submitted
     to the JDS Meeting and the subject of the Arrangement Resolution.

5.   THIS COURT ORDERS that JDS, if it deems it advisable, is specifically
     authorized to adjourn or postpone the JDS Meeting on one or more occasions,
     without the necessity of first convening the JDS Meeting or first obtaining
     any vote of holders of Common Shares respecting the adjournment or
     postponement.

6.   THIS COURT ORDERS that:

    (i) the Notice of Application herein;

    (ii) the Notice of the JDS Meeting;

                                      B-1

         the Joint Supplement (the "Joint Supplement") in substantially the same
         form as contained in Exhibits "A" and "F" to the Affidavit (with such
         amendments thereto as counsel for JDS may advise are necessary or
         desirable, provided that such amendments are not inconsistent with the
         terms of this Order); and

    (iv) any other communication or documents determined by JDS to be necessary
         or appropriate,

     shall be distributed to the holders of Common Shares and holders of options
     of JDS, by:

               Common Shares in accordance with the CBCA at least twenty-one
               (21) days prior to the date of the JDS Meeting, excluding the
               date of mailing and the date of the JDS Meeting;

           (b) in the case of non-registered holders of JDS Common Shares by
               providing multiple copies of the Joint Supplement to
               intermediaries and registered nominees to facilitate the broad
               distribution of the Circular to non-registered holders of JDS
               Common Shares; and

           (c) by delivering to the holders of options of JDS at least
               twenty-one (21) days prior to the date of the JDS Meeting
               excluding the date of delivery and the date for the JDS Meeting;

     and that such mailing, delivery and distribution shall constitute good and
     sufficient service of notice of the Application, the JDS Meeting and the
     hearing in respect of the Application.

7.   THE COURT ORDERS that the accidental omission to give notice of the JDS
     Meeting, or the non-receipt of such notice, shall not invalidate any
     resolution passed or proceedings taken at the JDS Meeting.

8.   THIS COURT ORDERS that JDS is authorized to use the form of proxy, in
     substantially the same form attached as Exhibit "G" to the Affidavit,
     subject to JDS's ability to insert dates and other relevant information in

     it may determine.

     of one (1) vote per Common Share and, subject to further Order of this
     court, the vote required to pass the Arrangement Resolution shall be the
     affirmative vote of not less than two-thirds of the votes cast (for this
     purpose any spoiled votes, illegible votes, defective votes and abstentions
     shall be deemed not to be votes cast) by the holders of Common Shares
     present in person or represented by proxy at the JDS Meeting.

10.  THIS COURT ORDERS that the only persons entitled to notice of or to attend
     the JDS Meeting shall be the holders of Common Shares as at the record date
     for the JDS Meeting, holders of valid proxies from such holders of Common
     Shares, JDS directors and auditors, and representatives of Uniphase
     Corporation and that the only persons entitled to be represented and to
     vote at the JDS Meeting shall be the holders of Common Shares as at the
     record date for the JDS Meeting subject to the provisions of the CBCA with
     respect to persons who become registered holders of shares after that date.

11.  THIS COURT ORDERS that the holders of Common Shares shall be entitled to
     exercise rights of dissent and appraisal, in accordance with section 190 of

                   to the number obtained by multiplying the stated capital of
                   the Class B Non-Voting Preference Shares, calculated as set
                   out in section 2.2.1.4, by the number of issued and
                   outstanding Class B Non-Voting Preference Shares transferred
                   to Exchangeco pursuant to section 2.2.2.2 and dividing that

                                      C-7

                   2.2.2.5.3.  there shall be deducted from the stated capital
                   account in the accounting records of Exchangeco maintained
                   for the Class B Non-Voting Preference Shares an amount equal
                   to the stated capital of the Class B Non-Voting Preference
                   Shares, calculated as set out in section 2.2.1.4, less the
                   amount previously deducted pursuant to section 2.2.2.5.1; and

                   2.2.2.5.4.  there shall be added to the stated capital

                   Preference Shares;

     2.2.3.   each outstanding JDS Option will become an option (a "Replacement
     Option") to purchase a number of Uniphase Common Shares equal to the
     product of the Exchange Ratio multiplied by the number of JDS Common Shares
     subject to such JDS Option. Such Replacement Option shall provide for an
     exercise price per Uniphase Common Share equal to the exercise price per
     share of such JDS Option immediately prior to the Effective Time divided by
     the Exchange Ratio. If the foregoing calculation results in a Replacement
     Option being exercisable for a fraction of a Uniphase Common Share, then
     the number of Uniphase Common Shares subject to such Replacement Option
     shall be rounded down to the next whole number of Uniphase Common Shares
     and the total exercise price for the Replacement Option will be reduced by
     the exercise price of the fractional Uniphase Common Share. The term to
     expiry, conditions to and manner of exercising, vesting schedule, and all
     other terms and conditions of such Replacement Option will otherwise be
     unchanged from those of the JDS Options, and any document or agreement
     previously evidencing a JDS Option shall thereafter evidence and be deemed
     to evidence such Replacement Option provided that, immediately prior to the
     Effective time, the board of Directors of JDS may resolve to accelerate the
     vesting schedule for all or a portion of the JDS Options such that,
     immediately following the Effective Time, the corresponding Replacement
     Options shall be immediately exercisable; and

     2.2.4.   coincident with and as part of the capital reorganization set out
     in section 2.2.2, Uniphase and Exchangeco shall execute the Voting and
     Exchange Trust Agreement and Uniphase shall issue to and deposit with the
     Trustee the Special Voting Share, in consideration of the payment to
     Uniphase of US$1.00 to be thereafter held of record by the Trustee as
     trustee for and on behalf of, and for the use and benefit of, the holders
     of the Exchangeable Shares in accordance with the Voting and Exchange Trust
     Agreement. All rights of holders of Exchangeable Shares under the Voting
     and Exchange Trust Agreement shall be received by them as part of the
     property receivable under section 2.2.2.2 in exchange for the Class B Non-
     Voting Preference Shares.

           Time, to the extent the fair value thereof is paid by Uniphase Nova
           Scotia, and to JDS immediately prior to the Effective Time, to the
           extent the fair value thereof is paid by JDS, and, in the case of JDS
           Common Shares so transferred to JDS, such shares shall be cancelled
           as of the Effective Time; or

     but in no case shall Uniphase, Exchangeco, Uniphase Nova Scotia, JDS,
     Amalco or any other Person be required to recognize such holders as holders
     of JDS Common Shares after the Effective Time, and the names of such
     holders of JDS Common Shares shall be deleted from the register of

                       CERTIFICATES AND FRACTIONAL SHARES

4.1.  ISSUANCE OF CERTIFICATES REPRESENTING EXCHANGEABLE SHARES

     At or promptly after the Effective Time, Exchangeco shall deposit with the
Depository, for the benefit of the holders of Class B Non-Voting Preference
Shares who will receive Exchangeable Shares in connection with the Arrangement,
certificates representing the Exchangeable Shares issued pursuant to section
2.2.2 upon the exchange of Class B Non-Voting Preference Shares. Upon surrender
to the Depository for cancellation of a certificate which immediately prior to
the Effective Time represented one or more JDS Common Shares or Holding Company
Shares that were converted into Class B Non-Voting Preference Shares on the
Amalgamation, which Class B Non-Voting Preference Shares were then subsequently
exchanged for Exchangeable Shares under the Arrangement, together with such
other documents and instruments as would have been required to effect the
transfer of the Class B Non-Voting Preference Shares under the CBCA and the
by-laws of Exchangeco and such additional documents and instruments as the
Depository may reasonably require, the holder of such surrendered certificate
shall be entitled to receive in exchange therefor, and the Depository shall
deliver to such holder, a certificate representing that number (rounded down to
the nearest whole number) of Exchangeable Shares which such holder has the right
to receive (together with any dividends or distributions with respect thereto
pursuant to section 4.3 and any cash in lieu of fractional Exchangeable Shares
pursuant to section 4.4), and the certificate so surrendered shall forthwith be
cancelled. For greater certainty, no certificates representing Class B
Non-Voting Preference Shares shall be issued and such Class B Non-Voting
Preference Shares shall be evidenced by the certificates representing JDS Common
Shares and Holding Company Shares converted into Class B Non-Voting Preference
Shares on the Amalgamation. In the event of a transfer of ownership of JDS
Common Shares that is not registered in the transfer records of JDS, a
certificate representing the proper number of Exchangeable Shares may be issued
to the transferee if the certificate representing the Class B Non-Voting
Preference Shares into which such JDS Common Shares were converted on the
Amalgamation is presented to the Depository, accompanied by all documents
required to evidence and effect such transfer. Until surrendered as contemplated
by this section 4.1, each certificate which immediately prior to the Effective
Time represented JDS Common Shares that were converted into Class B Non-Voting
Preference Shares on the Amalgamation (which certificate then represented such
Class B Non-Voting Preference Shares), which Class B Non-Voting Preference
Shares were then subsequently exchanged for Exchangeable Shares, shall be deemed
at all times after the Effective Time to represent only the right to receive
upon such surrender (i) the certificate representing Exchangeable Shares as
contemplated by this section 4.1, (ii) a cash payment in lieu of any fractional
Exchangeable Shares as contemplated by section 4.4, and (iii) any dividends or
distributions with a record date after the Effective Time theretofore paid or
payable with respect to Exchangeable Shares as contemplated by section 4.3.

4.2.  EXCHANGE OF CERTIFICATES FOR UNIPHASE COMMON SHARES

Preference Shares who will receive Uniphase Common Shares in connection with the
Arrangement, certificates representing the Uniphase Common Shares issued
pursuant to section 2.2.2 upon the exchange of Class B Non-Voting Preference
Shares. Upon surrender to the Depository for cancellation of a certificate which
immediately prior to the Effective Time represented one or more JDS

                                      C-9

Common Shares or Holding Company Shares that were converted into Class B
Non-Voting Preference Shares on the Amalgamation, which Class B Non-Voting
Preference Shares were then subsequently exchanged for Uniphase Common Shares
under the Arrangement, together with such other documents and instruments as
would have been required to effect the transfer of the Class B Non-Voting
Preference Shares under the CBCA and the by-laws of Exchangeco and such
additional documents and instruments as the Depository may reasonably require,
the holder of such surrendered certificate shall be entitled to receive in
exchange therefor, and the Depository shall deliver to such holder, a
certificate representing that number (rounded down to the nearest whole number)
of Uniphase Common Shares which such holder has the right to receive (together
with any dividends or distributions with respect thereto pursuant to section 4.3
and any cash in lieu of fractional JDS Common Shares pursuant to section 4.4),
and the certificate so surrendered shall forthwith be cancelled. For greater
certainty, no certificates representing Class B Non-Voting Preference Shares
shall be issued and such Class B Non-Voting Preference Shares shall be evidenced
by the certificates representing JDS Common Shares and Holding Company Shares
converted into Class B Non-Voting Preference Shares on the Amalgamation. In the
event of a transfer of ownership of JDS Common Shares that is not registered in
the transfer records of JDS, a certificate representing the proper number of
Uniphase Common Shares may be issued to the transferee if the certificate
representing the Class B Non-Voting Preference Shares into which such JDS Common
Shares were converted on the Amalgamation is presented to the Depository,
accompanied by all documents required to evidence and effect such transfer.
Until surrendered as contemplated by this section 4.2, each certificate which
immediately prior to the Effective Time represented one or more JDS Common
Shares that were converted into Class B Non-Voting Preference Shares on the
Amalgamation (which certificate then represented such Class B Non-Voting
Preference Shares), which Class B Non-Voting Preference Shares were then
subsequently exchanged for Uniphase Common Shares shall be deemed at all times
after the Effective Time to represent only the right to receive upon such
surrender (i) the certificate representing Uniphase Common Shares as
contemplated by this section 4.2, (ii) a cash payment in lieu of any fractional
Uniphase Common Shares as contemplated by section 4.4, and (iii) any dividends
or distributions with a record date after the Effective Time theretofore paid or
payable with respect to Uniphase Common Shares as contemplated by section 4.3.

4.3.  DISTRIBUTIONS WITH RESPECT TO UNSURRENDERED CERTIFICATES

     No dividends or other distributions declared or made after the Effective
Time with respect to Exchangeable Shares or Uniphase Common Shares with a record
date after the Effective Time shall be paid to the holder of any unsurrendered
certificate which immediately prior to the Effective Time represented
outstanding JDS Common Shares that were converted into Class B Non-Voting
Preference Shares on the Amalgamation, which Class B Non-Voting Preference
Shares were then subsequently exchanged pursuant to section 2.2.2, and no cash
payment in lieu of fractional shares shall be paid to any such holder pursuant
to section 4.4, unless and until the holder of record of such certificate shall
surrender such certificate in accordance with section 4.1 or 4.2. Subject to
applicable law, at the time of such surrender of any such certificate, there
shall be paid to the record holder of the certificates representing JDS Common
Shares or Holding Company Shares, without interest, (i) the amount of any cash
payable in lieu of a fractional Exchangeable Share or Uniphase Common Share to
which such holder is entitled pursuant to section 4.4, (ii) the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole Exchangeable Shares or Uniphase
Common Shares, as the case may be, the holder is entitled to receive and (iii)
on the appropriate payment date, the amount of dividends or other distributions
with a record date after the Effective Time but prior to surrender and a payment
date subsequent to surrender payable with respect to such whole Exchangeable
Shares or Uniphase Common Shares, as the case may be, the holder is entitled to
receive.

4.4.  NO FRACTIONAL SHARES

     If as a result of the Amalgamation, a Person shall become entitled to a
fractional interest in a Class B Non-Voting Preference Share, the fractional
interest in that Class B Non-Voting Preference Share shall be rounded to the
nearest one hundred thousandth of a Class B Non-Voting Preference Share and that
fractional interest, as so rounded, together with any whole Class B Non-Voting
Preference Shares that Person is entitled to receive on the Amalgamation, shall
be evidenced by the certificates representing the JDS Common Shares or Holding
Company Shares held by that Person which were converted into such Class B
Non-Voting Preference Shares on the Amalgamation.

                                      C-10

     No certificates or scrip representing fractional Exchangeable Shares or
fractional Uniphase Common Shares shall be issued upon the surrender for
exchange of certificates pursuant to section 4.1 or 4.2 and no dividend, stock
split or other change in the capital structure of Exchangeco or Uniphase, as the
case may be, shall relate to any such fractional security and such fractional
interests shall not entitle the owner thereof to exercise any rights as a
security holder of Exchangeco or Uniphase, as the case may be. In lieu of any
such fractional securities:

     4.4.1.   each Person otherwise entitled to a fractional interest in an
     Exchangeable Share will receive a cash payment equal to such Person's PRO
     RATA portion of the net proceeds after expenses received by the Depository
     upon the sale of whole shares representing an accumulation of all
     fractional interests in Exchangeable Shares to which all such Persons would
     otherwise be entitled. The Depository will sell such Exchangeable Shares by
     private sale (including by way of sale through the facilities of any stock
     exchange upon which the Exchangeable Shares are then listed) as soon as
     reasonably practicable following the Effective Date. The aggregate net
     proceeds after expenses of such sale will be distributed by the Depository,
     PRO RATA in relation to the respective fractions, among the Persons
     otherwise entitled to receive fractional interests in Exchangeable Shares;
     and

     4.4.2.   each Person otherwise entitled to a fractional interest in a
     Uniphase Common Share will receive a cash payment equal to such Person's
     PRO RATA portion of the net proceeds after expenses received by the
     Depository upon the sale of whole shares representing an accumulation of
     all fractional interests in Uniphase Common Shares to which all such
     Persons would otherwise be entitled. The Depository will sell such Uniphase
     Common Shares on NASDAQ as soon as reasonably practicable following the
     Effective Date. The aggregate net proceeds after expenses of such sale will
     be distributed by the Depository, PRO RATA in relation to the respective
     fractions, among Persons otherwise entitled to receive fractional interests
     in Uniphase Common Shares.

represented one or more outstanding JDS Common Shares that were converted into
Class B Non-Voting Preference Shares on the Amalgamation (which certificate then
represented such Class B Non-Voting Preference Shares), and which Class B
Non-Voting Preference Shares were then subsequently exchanged pursuant to
section 2.2.2, shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the Person claiming such certificate to be lost,
stolen or destroyed, the Depository will issue in exchange for such lost, stolen
or destroyed certificate, one or more certificates representing one or more
Exchangeable Shares or Uniphase Common Shares (and a cheque for any dividends or
distributions with respect thereto and any cash pursuant to section 4.4)
deliverable in accordance with such holder's JDS Letter of Transmittal and
Election Form. When authorizing such payment in exchange for any lost, stolen or
destroyed certificate, the Person to whom certificates representing Exchangeable
Shares or Uniphase Common Shares are to be issued shall, as a condition
precedent to the issuance thereof, give a bond satisfactory to Exchangeco,
Uniphase Nova Scotia, Uniphase and their respective transfer agents in such sum
as Exchangeco, Uniphase Nova Scotia and Uniphase may direct or otherwise
indemnify Exchangeco, Uniphase Nova Scotia and Uniphase in a manner satisfactory
to Exchangeco, Uniphase Nova Scotia and Uniphase against any claim that may be
made against Exchangeco, Uniphase Nova Scotia or Uniphase with respect to the
certificate alleged to have been lost, stolen or destroyed.

4.6.  EXTINCTION OF RIGHTS

     Any certificate which immediately prior to the Effective Time represented
outstanding JDS Common Shares that were converted into Class B Non-Voting
Preference Shares on the Amalgamation (which certificate then represented such
Class B Non-Voting Preference Shares), and which Class B Non-Voting Preference
Shares were then subsequently exchanged pursuant to section 2.2.2, and not
deposited, with all other instruments required by section 4.1 or 4.2, on or
prior to the sixth anniversary of the Effective Date shall cease to represent a
claim or interest of any kind or nature as a shareholder of Exchangeco or
Uniphase. On such date, the Exchangeable Shares or Uniphase Common Shares
(and/or cash in lieu of fractional interests therein, as provided in section
4.4) to which the former registered holder of the certificate referred to in the
preceding sentence was ultimately entitled shall be deemed to have been
surrendered to Exchangeco or Uniphase, as the

                                      C-11

case may be, together with all entitlements to dividends, distributions and
interest thereon held for such former registered holder.

4.7.  WITHHOLDING RIGHTS

     Exchangeco, Uniphase Nova Scotia, Uniphase and the Depository shall be
entitled to deduct and withhold from any dividend or consideration otherwise
payable to any holder of JDS Common Shares, Class B Non-Voting Preference
Shares, Uniphase Common Shares or Exchangeable Shares, such amounts as
Exchangeco, Uniphase Nova Scotia, Uniphase or the Depository is required or
permitted to deduct and withhold with respect to such payment under the ITA, the
United States Internal Revenue Code of 1986 or any provision of provincial,
state, local or foreign tax Law, in each case, as amended. To the extent that
amounts are so withheld, such withheld amounts shall be treated for all purposes
hereof as having been paid to the holder of the shares in respect of which such
deduction and withholding was made, provided that such withheld amounts are
actually remitted to the appropriate taxing authority. To the extent that the
amount so required or permitted to be deducted or withheld from any payment to a
holder exceeds the cash portion of the consideration otherwise payable to the
holder, Exchangeco, Uniphase Nova Scotia, Uniphase and the Depository are hereby
authorized to sell or otherwise dispose of such portion of the consideration as
is necessary to provide sufficient funds to Exchangeco, Uniphase Nova Scotia,
Uniphase or the Depository, as the case may be, to enable it to comply with such
deduction or withholding requirement and Exchangeco, Uniphase Nova Scotia,
Uniphase or the Depository shall notify the holder thereof and remit to the
holder any unapplied balance of the net proceeds of such sale.

                                   ARTICLE 5.
                     CERTAIN RIGHTS OF UNIPHASE NOVA SCOTIA
                         TO ACQUIRE EXCHANGEABLE SHARES

5.1.  UNIPHASE NOVA SCOTIA LIQUIDATION CALL RIGHT

     5.1.1.   Uniphase Nova Scotia shall have the overriding right (the
     "Liquidation Call Right"), in the event of and notwithstanding the proposed
     liquidation, dissolution or winding-up of Exchangeco pursuant to Article 5
     of the Exchangeable Share Provisions, to purchase from all but not less
     than all of the holders of Exchangeable Shares (other than any holder of
     Exchangeable Shares which is an affiliate of Uniphase) on the Liquidation
     Date all but not less than all of the Exchangeable Shares held by each such
     holder on payment by Uniphase Nova Scotia of an amount per share (the
     "Liquidation Call Purchase Price") equal to the Current Market Price of a
     Uniphase Common Share on the last Business Day prior to the Liquidation
     Date, which shall be satisfied in full by Uniphase Nova Scotia causing to
     be delivered to such holder one Uniphase Common Share, plus, to the extent
     not paid by Exchangeco, an additional amount equivalent to the full amount
     of all declared and unpaid dividends on each such Exchangeable Share held
     by such holder on any dividend record date which occurred prior to the date
     of purchase by Uniphase Nova Scotia (the "Dividend Amount"). In the event
     of the exercise of the Liquidation Call Right by Uniphase Nova Scotia, each
     holder shall be obligated to sell all of the Exchangeable Shares held by
     the holder to Uniphase Nova Scotia on the Liquidation Date on payment by
     Uniphase Nova Scotia to the holder of the Liquidation Call Purchase Price
     for each such share, and Exchangeco shall have no obligation to pay the
     Liquidation Amount of such shares so purchased by Uniphase Nova Scotia.

     5.1.2.   To exercise the Liquidation Call Right, Uniphase Nova Scotia must
     notify Exchangeco's transfer agent (the "Transfer Agent"), as agent for the
     holders of Exchangeable Shares, and Exchangeco of Uniphase Nova Scotia's
     intention to exercise such right at least 45 days before the Liquidation
     Date in the case of a voluntary liquidation, dissolution or winding-up of
     Exchangeco and at least five Business Days before the Liquidation Date in
     the case of an involuntary liquidation, dissolution or winding-up of
     Exchangeco. The Transfer Agent will notify the holders of Exchangeable
     Shares as to whether or not Uniphase Nova Scotia has exercised the
     Liquidation Call Right forthwith after the expiry of the period during
     which the same may be exercised by Uniphase Nova Scotia. If Uniphase Nova
     Scotia exercises the Liquidation Call Right, then on the Liquidation Date
     Uniphase Nova Scotia will purchase and the holders

                                      C-12

     will sell all of the Exchangeable Shares then outstanding for a price per
     share equal to the Liquidation Call Purchase Price.

     5.1.3.   For the purposes of completing the purchase of the Exchangeable
     Shares pursuant to the Liquidation Call Right, Uniphase Nova Scotia shall
     deposit with the Transfer Agent, on or before the Liquidation Date,
     certificates representing the aggregate number of Uniphase Common Shares
     deliverable by Uniphase Nova Scotia and a cheque or cheques of Uniphase
     Nova Scotia payable at par at any branch of the bankers of Uniphase Nova
     Scotia representing the aggregate Dividend Amount in payment of the total
     Liquidation Call Purchase Price, less any amounts withheld pursuant to
     section 4.7 hereof. Provided that Uniphase Nova Scotia has complied with
     the immediately preceding sentence, on and after the Liquidation Date, the
     rights of each holder of Exchangeable Shares will be limited to receiving
     such holder's proportionate part of the total Liquidation Call Purchase
     Price payable by Uniphase Nova Scotia upon presentation and surrender by
     the holder of certificates representing the Exchangeable Shares held by
     such holder and the holder shall on and after the Liquidation Date be
     considered and deemed for all purposes to be the holder of the Uniphase
     Common Shares to which it is entitled. Upon surrender to the Transfer Agent
     of a certificate or certificates representing Exchangeable Shares, together
     with such other documents and instruments as may be required to effect a
     transfer of Exchangeable Shares under the CBCA and the by-laws of
     Exchangeco and such additional documents and instruments as the Transfer
     Agent may reasonably require, the holder of such surrendered certificate or
     certificates shall be entitled to receive in exchange therefor, and the
     Transfer Agent on behalf of Uniphase Nova Scotia shall deliver to such
     holder, certificates representing the Uniphase Common Shares to which the
     holder is entitled and a cheque or cheques of Uniphase Nova Scotia payable
     at par at any branch of the bankers of Uniphase Nova Scotia in payment of
     the remaining portion, if any, of the total Liquidation Call Purchase
     Price, less any amounts withheld pursuant to section 4.7 hereof. If
     Uniphase Nova Scotia does not exercise the Liquidation Call Right in the
     manner described above, on the Liquidation Date the holders of the
     Exchangeable Shares will be entitled to receive in exchange therefor the
     liquidation price otherwise payable by Exchangeco in connection with the
     liquidation, dissolution or winding-up of Exchangeco pursuant to Article 5
     of the Exchangeable Share Provisions.

5.2.  UNIPHASE NOVA SCOTIA REDEMPTION CALL RIGHT

     5.2.1.   Uniphase Nova Scotia shall have the overriding right (the
     "Redemption Call Right"), notwithstanding the proposed redemption of
     Exchangeable Shares by Exchangeco pursuant to Article 7 of the Exchangeable
     Share Provisions, to purchase from all but not less than all of the holders
     of Exchangeable Shares (other than any holder of Exchangeable Shares which
     is an affiliate of Uniphase) on the Redemption Date all but not less than
     all of the Exchangeable Shares held by each such holder on payment by
     Uniphase Nova Scotia to each holder of an amount per Exchangeable Share
     (the "Redemption Call Purchase Price") equal to the Current Market Price of
     a Uniphase Common Share on the last Business Day prior to the Redemption
     Date, which shall be satisfied in full by Uniphase Nova Scotia causing to
     be delivered to such holder one Uniphase Common Share, plus the Dividend
     Amount. In the event of the exercise of the Redemption Call Right by
     Uniphase Nova Scotia, each holder shall be obligated to sell all of the
     Exchangeable Shares held by the holder to Uniphase Nova Scotia on the
     Redemption Date on payment by Uniphase Nova Scotia to the holder of the
     Redemption Call Purchase Price for each such share, and Exchangeco shall
     have no obligation to redeem such shares so purchased by Uniphase Nova
     Scotia.

     5.2.2.   To exercise the Redemption Call Right, Uniphase Nova Scotia must
     notify the Transfer Agent, as agent for the holders of Exchangeable Shares,
     and Exchangeco of Uniphase Nova Scotia's intention to exercise such right
     at least 60 days before the Redemption Date, except in the case of a
     redemption occurring as a result of a Uniphase Control Transaction, an
     Exchangeable Share Voting Event or an Exempt Exchangeable Share Voting
     Event, in which case Uniphase Nova Scotia shall so notify the Transfer
     Agent and Exchangeco on or before the Redemption Date. The Transfer Agent
     will notify the holders of Exchangeable Shares as to whether or not
     Uniphase Nova Scotia has exercised the Redemption Call Right forthwith
     after the expiry of the period during which the same may be exercised by
     Uniphase Nova Scotia. If Uniphase Nova Scotia exercises the Redemption Call
     Right, then on the Redemption Date, Uniphase

                                      C-13

     Nova Scotia will purchase and the holders will sell all of the Exchangeable
     Shares then outstanding for a price per share equal to the Redemption Call
     Purchase Price.

     5.2.3.   For the purposes of completing the purchase of the Exchangeable
     Shares pursuant to the Redemption Call Right, Uniphase Nova Scotia shall
     deposit with the Transfer Agent, on or before the Redemption Date,
     certificates representing the aggregate number of Uniphase Common Shares
     deliverable by Uniphase Nova Scotia and a cheque or cheques of Uniphase
     Nova Scotia payable at par at any branch of the bankers of Uniphase Nova
     Scotia representing the aggregate Dividend Amount in payment of the total
     Redemption Call Purchase Price, less any amounts withheld pursuant to
     section 4.7 hereof. Provided that Uniphase Nova Scotia has complied with
     the immediately preceding sentence, on and after the Redemption Date, the
     rights of each holder of Exchangeable Shares will be limited to receiving
     such holder's proportionate part of the total Redemption Call Purchase
     Price payable by Uniphase Nova Scotia upon presentation and surrender by
     the holder of certificates representing the Exchangeable Shares held by
     such holder and the holder shall on and after the Redemption Date be
     considered and deemed for all purposes to be the holder of the Uniphase
     Common Shares to which it is entitled. Upon surrender to the Transfer Agent
     of a certificate or certificates representing Exchangeable Shares, together
     with such other documents and instruments as may be required to effect a
     transfer of Exchangeable Shares under the CBCA and the by-laws of
     Exchangeco and such additional documents and instruments as the Transfer
     Agent may reasonably require, the holder of such surrendered certificate or
     certificates shall be entitled to receive in exchange therefor, and the
     Transfer Agent on behalf of Uniphase Nova Scotia shall deliver to such
     holder, certificates representing the Uniphase Common Shares to which the
     holder is entitled and a cheque or cheques of Uniphase Nova Scotia payable
     at par at any branch of the bankers of Uniphase Nova Scotia in payment of
     the remaining portion, if any, of the total Redemption Call Purchase Price,
     less any amounts withheld pursuant to section 4.7. hereof. If Uniphase Nova
     Scotia does not exercise the Redemption Call Right in the manner described
     above, on the Redemption Date the holders of the Exchangeable Shares will
     be entitled to receive in exchange therefor the redemption price otherwise
     payable by Exchangeco in connection with the redemption of the Exchangeable
     Shares pursuant to Article 7 of the Exchangeable Share Provisions.

                                   ARTICLE 6.

2.   LIQUIDATION, DISSOLUTION OR WINDING UP

     In the event of the liquidation, dissolution or winding up of the

                                      C-15

              PROVISIONS ATTACHING TO THE AMALCO PREFERENCE SHARES

    The preference shares shall have the following rights, privileges,

1.   RANKING

     The preference shares shall be entitled to a preference over the common

the Corporation ranking junior to the preference shares with respect to the
payment of dividends and the distribution of property or assets in the event of
the liquidation, dissolution or winding up of the Corporation, whether voluntary
or involuntary, or any other distribution of property or assets of the
Corporation among its shareholders for the purpose of winding up its affairs but
shall not have any further right to participate in profits.

2.   VOTING RIGHTS

     The holders of the preference shares shall not be entitled to receive
notice of or to attend or to vote at any meeting of shareholders of the
Corporation and shall not be entitled to vote separately as a class upon any

of the shares of any class of shares or series thereof, or to effect an
exchange, reclassification or cancellation of the preference shares, or to
create a new class of shares or series thereof having rights or privileges equal
or superior to the preference shares, provided, however, that notwithstanding
the foregoing provisions of this section 2, the holders of the preference shares
shall be entitled to vote separately as a class in respect of any matter for
which a separate vote is specifically provided in the CANADA BUSINESS
CORPORATIONS ACT (the "CBCA") or any successor statute thereto, other than in
respect of a proposal to amend the articles in a manner as hereinbefore in this
section 2 specified.

3.   DIVIDENDS

     The holders of the preference shares shall be entitled to receive in each
financial year of the Corporation, if, as and when declared by the board of
directors of the Corporation out of monies of the Corporation properly
applicable to the payment of dividends, non-cumulative preferential cash
dividends in the amount of 5 CENTS ($0.05) per preference share per annum. If in
any financial year of the Corporation the board of directors in their discretion
shall not declare the preferential dividends or any part thereof on the
preference shares then the right of the holders of the preference shares to
preferential dividends or any greater preferential dividends than the
preferential dividends actually declared for such financial year shall be
forever extinguished. The holders of the preference shares shall not be entitled
to any dividends other than or in excess of the preferential cash dividends
provided for in this section 3.

4.   REDEMPTION BY CORPORATION

     Subject to the provisions of the CBCA, the Corporation shall be entitled
upon giving notice as hereinafter provided, at any time from and after September
1, 2019 to redeem any or all of the preference shares registered in the name of
a holder for an amount per share equal to (a) $1.00 per preference share (the
"redemption amount") plus (b) all dividends declared and unpaid thereon to and
including the redemption date (collectively, the "redemption price").

     In case a part only of the preference shares is at any time to be redeemed,
the shares so to be redeemed may be selected by lot in such manner as the board
of directors of the Corporation in their sole discretion shall be resolution
determine or redemption may be effected on a pro rate basis disregarding
fractions. If a part only of the preference shares represented by any
certificate shall be redeemed, a new certificate representing the balance of
such shares shall be issued to the holder thereof at the expense of the
Corporation upon presentation and surrender of the first-mentioned certificate.

     In any case of redemption of preference shares, the Corporation shall at
least ten (10) days before the date specified for redemption mail to each person
who at the date of mailing is a registered holder of preference shares to be
redeemed a notice in writing of the intention of the Corporation to redeem such
preference shares. Such notice shall set out the number of preference shares
held by the person to whom it is addressed which are

                                      C-16

to be redeemed, the redemption price and the date on which redemption is to take
place. On or after the date so specified for redemption, the Corporation shall
pay or cause to be paid to or to the order of the registered holders of the
preference shares to be redeemed the redemption price (less any tax required to
be deducted and withheld therefrom by the Corporation) of such shares on
presentation and surrender, at the registered office of the Corporation or at
any other place or places within Canada as may be specified in such notice, of
the certificate(s) representing the preference shares so called for redemption
with such other documents and instruments as may be required to effect a
transfer of preference shares under the CBCA and the by-laws of the Corporation
and such additional documents and instruments as the Corporation may reasonably
require. Payment of the total redemption price for such preference shares shall
be made by delivery to each holder, at the address of the holder recorded in the
securities register of the Corporation or by holding for pick up by the holder
at the registered office of the Corporation of a cheque of the Corporation in
respect of the redemption price (less any tax required to be deducted and
withheld therefrom by the Corporation) payable at par at any branch in Canada of
the bankers of the Corporation for the time being. From and after the date
specified for redemption in any such notice, the preference shares called for
redemption shall cease to be entitled to dividends or any other participation in
the property or assets of the Corporation and the holders thereof shall not be
entitled to exercise any of the other rights of shareholders in respect thereof
unless payment of the redemption price shall not be made upon presentation and
surrender of the certificate(s) in accordance with the foregoing provisions, in
which case the rights of the holders shall remain unaffected.

     The Corporation shall have the right at any time after the mailing of
notice of its intention to redeem the preference shares to deposit the
redemption price of the preference shares so called for redemption or of such of
the said shares represented by certificate(s) which have not at the date of such
deposit been surrendered by the holders thereof in connection with such
redemption to a special account in any chartered bank or any trust company in
Canada named in such notice, to be paid without interest to or to the order of
the respective holders of preference shares called for redemption upon
presentation and surrender to such bank or trust company of the certificate(s)
representing such shares. Upon such deposit being made or upon the date
specified for redemption in such notice, whichever is the later, the preference
shares in respect of which such deposit shall have been made shall be deemed to
be redeemed and the rights of the holders thereof shall be limited to receiving
without interest their proportionate part of the amount so deposited upon
presentation and surrender of the certificate(s) held by them respectively. Any
interest allowed on any such deposit shall belong to the Corporation.

     Redemption monies which are represented by a cheque which has not been
presented to the Corporation's bankers for payment or that otherwise remain
unclaimed (including monies held on deposit in a special account as provided for
above) for a period of six years from the date specified for redemption shall be
forfeited to the Corporation.

5.   LIQUIDATION, DISSOLUTION OR WINDING UP

     In the event of the Liquidation, dissolution or winding up of the
Corporation, or any other distribution of property or assets of the Corporation
among its shareholders for the purpose of winding up its affairs, and after
payment to the holders of the shares of any class or series of shares in the
capital of the Corporation ranking senior to the preference shares of amounts
they are entitled to, the holders of the preference shares shall be entitled to
receive from the property and assets of the Corporation a sum equal to the
redemption amount of the preference shares held by them respectively plus all
dividends declared and unpaid thereon to and including the date of payment and
no more, in priority to the rights of the holders of the common shares and the
shares of any other class or series of shares in the capital of the Corporation
ranking junior to the preference shares. After payment to the holders of the
preference shares of the amounts so payable to them, they shall not be entitled
to share in any further distribution of the property or assets of the
Corporation.

6.   NOTICES

     Any notice, cheque, notice of redemption or other communication from the
Corporation herein provided for shall be either sent to the holders of the
preference shares by ordinary unregistered mail, postage prepaid, or delivered
by hand to such holders, at their respective addresses appearing on the
securities register of the Corporation or, in the event of the address of any
such holder not so appearing, then at the last address known

                                      C-17

to the Corporation of such holder. Accidental failure to give any such notice,
notice of redemption or other communication to one or more holders of preference
shares shall not affect the validity thereof, but, upon such failure being
discovered, a copy of the notice, notice of redemption or other communication,
as the case may be, shall be sent or delivered forthwith to such holder or
holders. Unless otherwise provided herein, any notice, certificate or other
communication from a holder of preference shares herein provided for shall be
either sent to the Corporation by ordinary unregistered mail, postage prepaid,
or delivered by hand to the Corporation, at its registered office. Any notice or
other communication, including without limitation a notice of redemption or
request for redemption, from the Corporation to the holders of the preference
shares or from a holder of preference shares to the Corporation may be waived.

    The Class B non-voting preference shares shall have the following rights,
privileges, restrictions and conditions:

     The Class B non-voting preference shares shall rank junior to the
Exchangeable Shares, the Class A non-voting preference shares and the shares of
any other class or series ranking senior to the Class B non-voting preference
shares with respect to the payment of dividends and the distribution of assets
in the event of the liquidation, dissolution or winding-up of the Corporation,
whether voluntary or involuntary, or any other distribution of the assets of the
Corporation among its shareholders for the purpose of winding up its affairs.
The Class B non-voting preference shares shall rank senior to the common shares
with respect to the payment of the Preferential Dividend Amount (as defined
below) in respect to each financial year of the Corporation but shall rank
equally with the common shares with respect to the payment of dividends in any
financial year in excess of the Preferential Dividend Amount and shall rank
senior to the common shares with respect to the payment of the Liquidation
Amount (as defined below) in the event of the liquidation, dissolution or
winding-up of the Corporation, whether voluntary or involuntary, or any other
distribution of the assets of the Corporation among its shareholders for the
purpose of winding up its affairs.

2.   VOTING RIGHTS

     The holders of the Class B non-voting preference shares shall not be
entitled to receive notice of or to attend or to vote at any meeting of
shareholders of the Corporation and shall not be entitled to vote separately as
a class upon any proposal to amend the articles of the Corporation to change the
maximum number of the shares of any class of shares or series thereof, or to
effect an exchange, reclassification or cancellation of the Class B non-voting
preference shares, or to create a new class of shares or series thereof having
rights or privileges equal or superior to the Class B non-voting preference
shares, provided, however, that notwithstanding the foregoing provisions of this
section 2, the holders of the Class B non-voting preference shares shall be
entitled to vote separately as a class in respect of any matter for which a
separate vote is specifically provided in the CANADA BUSINESS CORPORATIONS ACT
or any successor statute thereto, other than in respect of a proposal to amend
the articles in a manner as hereinbefore in this section 2 specified.

3.   DIVIDENDS

     Subject always to the prior rights of the holders of the Exchangeable
Shares, the Class A non-voting preference shares and of any shares of any other
class or series ranking senior to the Class B non-voting preference shares, the
holders of the Class B non-voting preference shares shall be entitled, prior to
the payment of any dividends to the holders of common shares in any financial

non-cumulative preferential cash dividends in the amount of 8% of the
Liquidation Amount (as defined below) per Class B non-voting preference share

preference shares then the right of the holders of the Class B non-voting
preference shares to the Preferential Dividend Amount or any greater
preferential dividends than the preferential dividends actually declared for
such financial year shall be forever extinguished.

B non-voting preference share for a particular financial year of the
Corporation, the holders of the Class B non-voting preference shares and common
shares shall participate equally as to any additional dividends, if, as and when
declared by the board of directors of the Corporation and all additional
dividends which the directors may determine to declare and pay in any financial
year of the Corporation shall be declared and paid in equal or equivalent
amounts per share, out of money, assets or property of the Corporation properly
applicable to the payment of dividends or

                                      C-19

out of authorized but unissued shares of the Corporation, as applicable, on all
the Class B non-voting preference shares and common shares at the time
outstanding without preference or distinction.

4.   LIQUIDATION, DISSOLUTION OR WINDING-UP

     In the event of the liquidation, dissolution or winding up of the
Corporation, or any other distribution of the assets of the Corporation among
its shareholders for the purpose of winding up its affairs, and after payment to
the holders of the Exchangeable Shares, the Class A non-voting preference shares
and the shares of any other class or series of shares in the capital of the
Corporation ranking senior to the Class B non-voting preference shares of
amounts they are entitled to, the holders of the Class B non-voting preference
shares shall be entitled to receive from the property and assets of the
Corporation a sum equal to the Liquidation Amount (as defined below) of each
Class B non-voting preference share held by them respectively plus all dividends
declared and unpaid thereon to and including the date of payment and no more, in
priority to the rights of the holders of the common shares and the shares of any
other class or series of shares in the capital of the Corporation ranking junior
to the Class B non-voting preference shares. The "Liquidation Amount" of a Class
B non-voting preference share shall be equal to the quotient obtained by
dividing:

     (a) $6,500,000,000, by

     (b) the number of issued and outstanding Class B non-voting preference
       shares as of the date on which entitlements to the Liquidation Amount are
       fixed.

     After payment to the holders of the Class B non-voting preference shares of
the Liquidation Amounts so payable to them, they shall not be entitled to share
in any further distribution of the property or assets of the Corporation.

5.   NOTICES

     Any notice, cheque or other communication from the Corporation herein
provided for shall be sent to the holders of the Class B non-voting preference
shares by ordinary unregistered mail, postage prepaid, or delivered by hand to
such holders, at their respective addresses appearing on the securities register

Accidental failure to give any such notice or other communication to one or more
holders of Class B non-voting preference shares shall not affect the validity
thereof, but, upon such failure being discovered, a copy of the notice or other
communication shall be sent or delivered forthwith to such holder or holders.
Any notice or other communication from the Corporation to the holders of the
Class B non-voting preference shares may be waived.

                                   DIVIDENDS

3.1.  Subject to section 3.2 below, a holder of an Exchangeable Share shall be
entitled to receive and the Board of Directors shall, subject to applicable law,
on each Uniphase Dividend Declaration Date, declare a dividend on each
Exchangeable Share:

     (a) in the case of a cash dividend declared on the Uniphase Common Shares,

     (c) in the case of a dividend declared on the Uniphase Common Shares in
       property other than cash or Uniphase Common Shares, in such type and
       amount of property for each Exchangeable Share as is the same as or
       economically equivalent to (to be determined by the Board of Directors as
       contemplated by section 3.5 hereof) the type and amount of property
       declared as a dividend on each Uniphase Common Share.

Such dividends shall be paid out of money, assets or property of the Corporation
properly applicable to the payment of dividends, or out of authorized but
unissued shares of the Corporation, as applicable.

3.2.  In the case of a stock dividend declared on the Uniphase Common Shares to
be paid in Uniphase Common Shares, in lieu of declaring the stock dividend
contemplated by section 3.1(b) on the Exchangeable Shares, the Board of
Directors may, in its discretion and subject to applicable law, subdivide,
redivide or change (the "subdivision") each issued and unissued Exchangeable
Share on the basis that each Exchangeable Share before the subdivision becomes a
number of Exchangeable Shares as is equal to the sum of (i) a Uniphase Common
Share and (ii) the number of Uniphase Common Shares to be paid as a stock
dividend on each Uniphase Common Share. In such instance, and notwithstanding
any other provision hereof, such subdivision shall become effective on the
effective date specified in section 3.4 hereof without any further act or
formality on the part of the Board of Directors or of the holders of
Exchangeable Shares. For greater certainty, no approval of the holders of
Exchangeable Shares to an amendment to the articles of the Corporation shall be
required to give effect to such subdivision.

3.3.  Cheques of the Corporation payable at par at any branch of the bankers of
the Corporation shall be issued in respect of any cash dividends contemplated by
section 3.1(a) hereof and the sending of such a cheque to each holder of an
Exchangeable Share shall satisfy the cash dividend represented thereby unless
the cheque is not paid on presentation. Subject to applicable law, certificates
registered in the name of the registered holder of

                                      C-24

Exchangeable Shares shall be issued or transferred in respect of any stock
dividends contemplated by section 3.1(b) hereof or any subdivision of shares
contemplated by section 3.2 hereof and the sending of such a certificate to each
holder of an Exchangeable Share shall satisfy the stock dividend or share
subdivision represented thereby. Such other type and amount of property in
respect of any dividends contemplated by section 3.1(c) hereof shall be issued,
distributed or transferred by the Corporation in such manner as it shall
determine and the issuance, distribution or transfer thereof by the Corporation
to each holder of an Exchangeable Share shall satisfy the dividend represented
thereby. No holder of an Exchangeable Share shall be entitled to recover by
action or other legal process against the Corporation any dividend that is
represented by a cheque that has not been duly presented to the Corporation's
bankers for payment or that otherwise remains unclaimed for a period of six
years from the date on which such dividend was payable.

3.4.  The record date for the determination of the holders of Exchangeable
Shares entitled to receive payment of, and the payment date for, any dividend
declared on the Exchangeable Shares under section 3.1 hereof shall be the same
dates as the record date and payment date, respectively, for the corresponding
dividend declared on the Uniphase Common Shares. The record date for the
determination of the holders of Exchangeable Shares entitled to receive
Exchangeable Shares in connection with any subdivision of Exchangeable Shares
under section 3.2 hereof and the effective date of such subdivision shall be the
same dates as the record date and payment date, respectively, for the
corresponding stock dividend declared on Uniphase Common Shares.

3.5.  If on any payment date for any dividends declared on the Exchangeable
Shares under section 3.1 hereof the dividends are not paid in full on all of the
Exchangeable Shares then outstanding, any such dividends that remain unpaid
shall be paid on a subsequent date or dates determined by the Board of Directors
on which the Corporation shall have sufficient moneys, assets or property
properly applicable to the payment of such dividends.

3.6.  The Board of Directors shall determine, in good faith and in its sole
discretion, economic equivalence for the purposes of sections 3.1 and 3.2
hereof, and each such determination shall be conclusive and binding on the
Corporation and its shareholders. In making each such determination, the
following factors shall, without excluding other factors determined by the Board
of Directors to be relevant, be considered by the Board of Directors:

     (a) in the case of any stock dividend or other distribution payable in
       Uniphase Common Shares, the number of such shares issued in proportion to
       the number of Uniphase Common Shares previously outstanding;

     (b) in the case of the issuance or distribution of any rights, options or
       warrants to subscribe for or purchase Uniphase Common Shares (or
       securities exchangeable for or convertible into or carrying rights to
       acquire Uniphase Common Shares), the relationship between the exercise
       price of each such right, option or warrant and the current market value
       (as determined by the Board of Directors in the manner above
       contemplated) of a Uniphase Common Share;

     (c) in the case of the issuance or distribution of any other form of
       property (including without limitation any shares or securities of
       Uniphase of any class other than Uniphase Common Shares, any rights,
       options or warrants other than those referred to in section 3.6(b) above,
       any evidences of indebtedness of Uniphase or any assets of Uniphase), the
       relationship between the fair market value (as determined by the Board of
       Directors in the manner above contemplated) of such property to be issued
       or distributed with respect to each outstanding Uniphase Common Share and
       the current market value (as determined by the Board of Directors in the
       manner above contemplated) of a Uniphase Common Share; and

     (d) in all such cases, the general taxation consequences of the relevant
       event to holders of Exchangeable Shares to the extent that such
       consequences may differ from the taxation consequences to holders of
       Uniphase Common Shares as a result of differences between taxation laws
       of Canada and the United States (except for any differing consequences
       arising as a result of differing marginal taxation rates and without
       regard to the individual circumstances of holders of Exchangeable
       Shares).

     For purposes of the foregoing determinations, the current market value of
any security listed and traded or quoted on a securities exchange shall be the
average of the closing bid and ask prices of such security during a

                                      C-25

period of not less than 20 consecutive trading days ending not more than three
trading days before the date of determination on the principal securities
exchange on which such securities are listed and traded or quoted; provided,
however, that if in the opinion of the Board of Directors the public
distribution or trading activity of such securities during such period does not
create a market which reflects the fair market value of such securities, then
the current market value thereof shall be determined by the Board of Directors,
in good faith and in its sole discretion, and provided further that any such
determination by the Board of Directors shall be conclusive and binding on the
Corporation and its shareholders.

                                   ARTICLE 4
                              CERTAIN RESTRICTIONS

       Common Shares, the Preference Shares or any other shares ranking junior
       to the Exchangeable Shares;

       with the Exchangeable Shares with respect to the payment of dividends or
       on any liquidation distribution;

       shareholder rights plan adopted by the Corporation, (ii) by way of stock
       dividend to the holders of such Exchangeable Shares contemplated by
       section 3.1 hereof, or (iii) by way of any subdivision of Exchangeable
       Shares contemplated by section 3.2 hereof; or

     (e) issue any shares of the Corporation ranking equally with, or superior
       to, the Exchangeable Shares other than by way of stock dividends to the
       holders of such Exchangeable Shares.

     The restrictions in sections 4.1(a), 4.1(b), 4.1(c) and 4.1.(d) above shall
not apply if all dividends on the outstanding Exchangeable Shares corresponding
to dividends declared and paid to date on the Uniphase Common Shares shall have
been declared and paid on the Exchangeable Shares.

                                   ARTICLE 5
                          DISTRIBUTION ON LIQUIDATION

5.1.  In the event of the liquidation, dissolution or winding-up of the
Corporation or any other distribution of the assets of the Corporation among its
shareholders for the purpose of winding up its affairs, subject to the exercise
by Uniphase Nova Scotia of the Liquidation Call Right, a holder of Exchangeable
Shares shall be entitled, subject to applicable law, to receive from the assets
of the Corporation in respect of each Exchangeable Share held by such holder on
the effective date (the "Liquidation Date") of such liquidation, dissolution or
winding-up, before any distribution of any part of the assets of the Corporation
among the holders of the Common Shares, the Preference Shares or any other
shares ranking junior to the Exchangeable Shares, an amount per share equal to
the Current Market Price of a Uniphase Common Share on the last Business Day
prior to the Liquidation Date (the "Liquidation Amount"), which shall be
satisfied in full by the Corporation causing to be delivered to such holder one
Uniphase Common Share, together with all declared and unpaid dividends on each
such Exchangeable Share held by such holder on any dividend record date which
occurred prior to the Liquidation Date.

5.2.  On or promptly after the Liquidation Date, the Corporation shall cause to
be delivered to the holders of the Exchangeable Shares the Liquidation Amount
for each such Exchangeable Share upon presentation and surrender of the
certificates representing such Exchangeable Shares, together with such other
documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the CANADA BUSINESS

                                      C-26

CORPORATIONS ACT and the by-laws of the Corporation and such additional
documents and instruments as the Transfer Agent, Uniphase or the Corporation may
reasonably require, at the registered office of the Corporation or at any office
of the Transfer Agent as may be specified by the Corporation by notice to the
holders of the Exchangeable Shares. Payment of the total Liquidation Amount for
such Exchangeable Shares shall be made by delivery to each holder, at the
address of the holder recorded in the securities register of the Corporation for
the Exchangeable Shares or by holding for pick-up by the holder at the
registered office of the Corporation or at any office of the Transfer Agent as
may be specified by the Corporation by notice to the holders of Exchangeable
Shares, on behalf of the Corporation of certificates representing Uniphase
Common Shares (which shares shall be duly issued as fully paid and
non-assessable and shall be free and clear of any lien, claim or encumbrance)
and a cheque of the Corporation payable at par at any branch of the bankers of
the Corporation in respect of the remaining portion, if any, of the total
Liquidation Amount (in each case less any amounts withheld on account of tax
required to be deducted and withheld therefrom) (without interest). On and after
the Liquidation Date, the holders of the Exchangeable Shares shall cease to be
holders of such Exchangeable Shares and shall not be entitled to exercise any of
the rights of holders in respect thereof, other than the right to receive their
proportionate part of the total Liquidation Amount, unless payment of the total
Liquidation Amount for such Exchangeable Shares shall not be made upon
presentation and surrender of share certificates in accordance with the
foregoing provisions, in which case the rights of the holders shall remain
unaffected until the total Liquidation Amount has been paid in the manner
hereinbefore provided. The Corporation shall have the right at any time after
the Liquidation Date to deposit or cause to be deposited the total Liquidation
Amount in respect of the Exchangeable Shares represented by certificates that
have not at the Liquidation Date been surrendered by the holders thereof in a
custodial account with any chartered bank or trust company in Canada. Upon such
deposit being made, the rights of the holders of Exchangeable Shares after such
deposit shall be limited to receiving their proportionate part of the total
Liquidation Amount (in each case less any amounts withheld on account of tax
required to be deducted and withheld therefrom) (without interest) for such
Exchangeable Shares so deposited, against presentation and surrender of the said
certificates held by them, respectively, in accordance with the foregoing
provisions. Upon such payment or deposit of the total Liquidation Amount, the
holders of the Exchangeable Shares shall thereafter be considered and deemed for
all purposes to be holders of the Uniphase Common Shares delivered to them or
the custodian on their behalf.

5.3.  After the Corporation has satisfied its obligations to pay the holders of
the Exchangeable Shares the Liquidation Amount per Exchangeable Share pursuant
to section 5.1 of these share provisions, such holders shall not be entitled to
share in any further distribution of the assets of the Corporation.

                                   ARTICLE 6
                  RETRACTION OF EXCHANGEABLE SHARES BY HOLDER

6.1.  A holder of Exchangeable Shares shall be entitled at any time, subject to
the exercise by Uniphase Nova Scotia of the Retraction Call Right and otherwise
upon compliance with the provisions of this Article 6, to require the
Corporation to redeem any or all of the Exchangeable Shares registered in the
name of such holder for an amount per share equal to the Current Market Price of
a Uniphase Common Share on the last Business Day prior to the Retraction Date
(the "Retraction Price"), which shall be satisfied in full by the Corporation
causing to be delivered to such holder one Uniphase Common Share for each
Exchangeable Share presented and surrendered by the holder, together with, on
the payment date therefor, the full amount of all declared and unpaid dividends
on any such Exchangeable Share held by such holder on any dividend record date
which occurred prior to the Retraction Date. To effect such redemption, the
holder shall present and surrender at the registered office of the Corporation
or at any office of the Transfer Agent as may be specified by the Corporation by
notice to the holders of Exchangeable Shares the certificate or certificates
representing the Exchangeable Shares which the holder desires to have the
Corporation redeem, together with such other documents and instruments as may be
required to effect a transfer of Exchangeable Shares under the CANADA BUSINESS
CORPORATIONS ACT and the by-laws of the Corporation and such additional
documents and instruments as the Transfer Agent, Uniphase or the Corporation may
reasonably require, and together with a duly executed

                                      C-27

statement (the "Retraction Request") in the form of Schedule A hereto or in such
other form as may be acceptable to the Corporation:

     (a) specifying that the holder desires to have all or any number specified
       therein of the Exchangeable Shares represented by such certificate or
       certificates (the "Retracted Shares") redeemed by the Corporation;

     (b) stating the Business Day on which the holder desires to have the
       Corporation redeem the Retracted Shares (the "Retraction Date"), provided
       that the Retraction Date shall be not less than 10 Business Days nor more
       than 15 Business Days after the date on which the Retraction Request is
       received by the Corporation and further provided that, in the event that
       no such Business Day is specified by the holder in the Retraction
       Request, the Retraction Date shall be deemed to be the 15th Business Day
       after the date on which the Retraction Request is received by the
       Corporation; and

     (c) acknowledging the overriding right (the "Retraction Call Right") of
       Uniphase Nova Scotia to purchase all but not less than all the Retracted
       Shares directly from the holder and that the Retraction Request shall be
       deemed to be a revocable offer by the holder to sell the Retracted Shares
       to Uniphase Nova Scotia in accordance with the Retraction Call Right on
       the terms and conditions set out in section 6.3 below.

6.2.  Subject to the exercise by Uniphase Nova Scotia of the Retraction Call
Right, upon receipt by the Corporation or the Transfer Agent in the manner
specified in section 6.1 hereof of a certificate or certificates representing
the number of Exchangeable Shares which the holder desires to have the
Corporation redeem, together with a Retraction Request, and provided that the
Retraction Request is not revoked by the holder in the manner specified in
section 6.7, the Corporation shall redeem the Retracted Shares effective at the
close of business on the Retraction Date and shall cause to be delivered to such
holder the total Retraction Price with respect to such shares, provided that all
declared and unpaid dividends for which the record date has occurred prior to
the Retraction Date shall be paid on the payment date for such dividends. If
only a part of the Exchangeable Shares represented by any certificate is
redeemed (or purchased by Uniphase Nova Scotia pursuant to the Retraction Call
Right), a new certificate for the balance of such Exchangeable Shares shall be
issued to the holder at the expense of the Corporation.

6.3.  Upon receipt by the Corporation of a Retraction Request, the Corporation
shall immediately notify Uniphase Nova Scotia thereof. In order to exercise the
Retraction Call Right, Uniphase Nova Scotia must notify the Corporation of its
determination to do so (the "Uniphase Nova Scotia Call Notice") within five
Business Days of notification to Uniphase Nova Scotia by the Corporation of the
receipt by the Corporation of the Retraction Request. If Uniphase Nova Scotia
does not so notify the Corporation within such five Business Day period, the
Corporation will notify the holder as soon as possible thereafter that Uniphase
Nova Scotia will not exercise the Retraction Call Right. If Uniphase Nova Scotia
delivers the Uniphase Nova Scotia Call Notice within such five Business Day
period, and provided that the Retraction Request is not revoked by the holder in
the manner specified in section 6.7, the Retraction Request shall thereupon be
considered only to be an offer by the holder to sell the Retracted Shares to
Uniphase Nova Scotia in accordance with the Retraction Call Right. In such
event, the Corporation shall not redeem the Retracted Shares and Uniphase Nova
Scotia shall purchase from such holder and such holder shall sell to Uniphase
Nova Scotia on the Retraction Date the Retracted Shares for a purchase price
(the "Purchase Price") per share equal to the Retraction Price per share, plus,
on the designated payment date therefor, to the extent not paid by the
Corporation on the designated payment date therefor, an additional amount
equivalent to the full amount of all declared and unpaid dividends on those
Retracted Shares held by such holder on any dividend record date which occurred
prior to the Retraction Date (the "Dividend Amount"). For the purposes of
completing a purchase pursuant to the Retraction Call Right, Uniphase Nova
Scotia shall deposit with the Transfer Agent, on or before the Retraction Date,
certificates representing Uniphase Common Shares and a cheque or cheques of
Uniphase Nova Scotia payable at par at any branch of the bankers of Uniphase
Nova Scotia representing the aggregate Dividend Amount, less any amounts
withheld on account of tax required to be deducted and withheld therefrom
(without interest). Provided that Uniphase Nova Scotia has complied with the
immediately preceding sentence, the closing of the purchase and sale of the
Retracted Shares pursuant to the Retraction Call Right shall be deemed to have
occurred as at the close of business on the Retraction Date and, for greater
certainty, no redemption by the Corporation of such

                                      C-28

Retracted Shares shall take place on the Retraction Date. In the event that
Uniphase Nova Scotia does not deliver a Uniphase Nova Scotia Call Notice within
such five Business Day period, and provided that the Retraction Request is not
revoked by the holder in the manner specified in section 6.7, the Corporation
shall redeem the Retracted Shares on the Retraction Date and in the manner
otherwise contemplated in this Article 6.

6.4.  The Corporation or Uniphase Nova Scotia, as the case may be, shall deliver
or cause the Transfer Agent to deliver to the relevant holder, at the address of
the holder recorded in the securities register of the Corporation for the
Exchangeable Shares or at the address specified in the holder's Retraction
Request or by holding for pick-up by the holder at the registered office of the
Corporation or at any office of the Transfer Agent as may be specified by the
Corporation by notice to the holders of Exchangeable Shares, certificates
representing the Uniphase Common Shares (which shares shall be duly issued as
fully paid and non-assessable and shall be free and clear of any lien, claim or
encumbrance) registered in the name of the holder or in such other name as the
holder may request, and, if applicable and on or before the payment date
therefor, a cheque payable at par at any branch of the bankers of the
Corporation or Uniphase Nova Scotia, as applicable, representing the aggregate
Dividend Amount in payment of the total Retraction Price or the total Purchase
Price, as the case may be, in each case, less any amounts withheld on account of
tax required to be deducted and withheld therefrom (without interest), and such
delivery of such certificates and cheques on behalf of the Corporation or by
Uniphase Nova Scotia, as the case may be, or by the Transfer Agent shall be
deemed to be payment of and shall satisfy and discharge all liability for the
total Retraction Price or total Purchase Price, as the case may be, to the
extent that the same is represented by such share certificates and cheques (plus
any tax deducted and withheld therefrom and remitted to the proper tax
authority).

6.5.  On and after the close of business on the Retraction Date, the holder of
the Retracted Shares shall cease to be a holder of such Retracted Shares and
shall not be entitled to exercise any of the rights of a holder in respect
thereof, other than the right to receive his proportionate part of the total
Retraction Price or total Purchase Price, as the case may be, unless upon
presentation and surrender of certificates in accordance with the foregoing
provisions, payment of the total Retraction Price or the total Purchase Price,
as the case may be, shall not be made as provided in section 6.4, in which case
the rights of such holder shall remain unaffected until the total Retraction
Price or the total Purchase Price, as the case may be, has been paid in the
manner hereinbefore provided. On and after the close of business on the
Retraction Date, provided that presentation and surrender of certificates and
payment of the total Retraction Price or the total Purchase Price, as the case
may be, has been made in accordance with the foregoing provisions, the holder of
the Retracted Shares so redeemed by the Corporation or purchased by Uniphase
Nova Scotia shall thereafter be considered and deemed for all purposes to be a
holder of the Uniphase Common Shares delivered to it.

6.6.  Notwithstanding any other provision of this Article 6, the Corporation
shall not be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent that such redemption of Retracted Shares would
be contrary to solvency requirements or other provisions of applicable law. If
the Corporation believes that on any Retraction Date it would not be permitted
by any of such provisions to redeem the Retracted Shares tendered for redemption
on such date, and provided that Uniphase Nova Scotia shall not have exercised
the Retraction Call Right with respect to the Retracted Shares, the Corporation
shall only be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent of the maximum number that may be so redeemed
(rounded down to a whole number of shares) as would not be contrary to such
provisions and shall notify the holder at least two Business Days prior to the
Retraction Date as to the number of Retracted Shares which will not be redeemed
by the Corporation. In any case in which the redemption by the Corporation of
Retracted Shares would be contrary to solvency requirements or other provisions
of applicable law, the Corporation shall redeem the maximum number of
Exchangeable Shares which the Board of Directors determine the Corporation is,
on the Retraction Date, permitted to redeem, which shall be selected as nearly
as may be PRO RATA (disregarding fractions) in proportion to the total number of
Exchangeable Shares tendered for retraction by each holder thereof and the
Corporation shall issue to each holder of Retracted Shares a new certificate, at
the expense of the Corporation, representing the Retracted Shares not redeemed
by the Corporation pursuant to section 6.2 hereof. Provided that the Retraction
Request is not revoked by the holder in the manner specified in section 6.7 and
provided further that Uniphase Nova Scotia shall not have exercised the
Retraction Call Right with respect to the Retracted Shares, the holder of any
such Retracted Shares not

                                      C-29

redeemed by the Corporation pursuant to section 6.2 of these share provisions as
a result of solvency
requirements or other provisions of applicable law shall be deemed by giving the
Retraction Request to have instructed the Trustee to require Uniphase to
purchase such Retracted Shares from such holder on the Retraction Date or as
soon as practicable thereafter on payment by Uniphase to such holder of the
Purchase Price for each such Retracted Share, all as more specifically provided
in the Voting and Exchange Trust Agreement.

6.7.  A holder of Retracted Shares may, by notice in writing given by the holder
to the Corporation before the close of business on the Business Day immediately
preceding the Retraction Date, withdraw its Retraction Request, in which event
such Retraction Request shall be null and void and, for greater certainty, the
revocable offer constituted by the Retraction Request to sell the Retracted
Shares to Uniphase Nova Scotia shall be deemed to have been revoked.

                                   ARTICLE 7
              REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION

7.1.  Subject to applicable law, and provided Uniphase Nova Scotia has not
exercised the Redemption Call Right, the Corporation shall on the Redemption
Date redeem all but not less than all of the then outstanding Exchangeable
Shares for an amount per share equal to the Current Market Price of a Uniphase
Common Share on the last Business Day prior to the Redemption Date (the
"Redemption Price"), which shall be satisfied in full by the Corporation causing
to be delivered to each holder of Exchangeable Shares one Uniphase Common Share
for each Exchangeable Share held by such holder, together with the full amount
of all declared and unpaid dividends on each such Exchangeable Share held by
such holder on any dividend record date which occurred prior to the Redemption
Date.

7.2.  In any case of a redemption of Exchangeable Shares under this Article 7,
the Corporation shall, at least 60 days before the Redemption Date (other than a
Redemption Date established in connection with a Uniphase Control Transaction,
an Exchangeable Share Voting Event or an Exempt Exchangeable Share Voting
Event), send or cause to be sent to each holder of Exchangeable Shares a notice
in writing of the redemption by the Corporation or the purchase by Uniphase Nova
Scotia under the Redemption Call Right, as the case may be, of the Exchangeable
Shares held by such holder. In the case of a Redemption Date established in
connection with a Uniphase Control Transaction, an Exchangeable Share Voting
Event and an Exempt Exchangeable Share Voting Event, the written notice of
redemption by the Corporation or the purchase by Uniphase Nova Scotia under the
Redemption Call Right will be sent on or before the Redemption Date, on as many
days prior written notice as may be determined by the Board of Directors of the
Corporation to be reasonably practicable in the circumstances. In any such case,
such notice shall set out the Redemption Price or the Redemption Call Purchase
Price, as the case may be, the Redemption Date and, if applicable, particulars
of the Redemption Call Right.

7.3.  On or after the Redemption Date and subject to the exercise by Uniphase
Nova Scotia of the Redemption Call Right, the Corporation shall cause to be
delivered to the holders of the Exchangeable Shares to be redeemed the
Redemption Price for each such Exchangeable Share, together with the full amount
of all declared and unpaid dividends on each such Exchangeable Share held by
such holder on any dividend record date which occurred prior to the Redemption
Date, upon presentation and surrender at the registered office of the
Corporation or at any office of the Transfer Agent as may be specified by the
Corporation in such notice of the certificates representing such Exchangeable
Shares, together with such other documents and instruments as may be required to
effect a transfer of Exchangeable Shares under the CANADA BUSINESS CORPORATIONS
ACT and the by-laws of the Corporation and such additional documents and
instruments as the Transfer Agent, Uniphase or the Corporation may reasonably
require. Payment of the total Redemption Price for such Exchangeable Shares,
together with payment of such dividends, shall be made by delivery to each
holder, at the address of the holder recorded in the securities register of the
Corporation or by holding for pick-up by the holder at the registered office of
the Corporation or at any office of the Transfer Agent as may be specified by
the Corporation in such notice, on behalf of the Corporation of certificates
representing Uniphase Common Shares (which shares shall be duly issued as fully
paid and non-assessable and shall be free and clear of any lien, claim or
encumbrance) and, if applicable, a cheque of the Corporation payable at par at
any branch of the bankers of the Corporation in

                                      C-30

payment of any such dividends, in each case, less any amounts withheld on
account of tax required to be deducted and withheld therefrom (without
interest). On and after the Redemption Date, the holders of the Exchangeable
Shares called for redemption shall cease to be holders of such Exchangeable
Shares and shall not be entitled to exercise any of the rights of holders in
respect thereof, other than the right to receive their proportionate part of the
total Redemption Price and any such dividends, unless payment of the total
Redemption Price and any such dividends for such Exchangeable Shares shall not
be made upon presentation and surrender of certificates in accordance with the
foregoing provisions, in which case the rights of the holders shall remain
unaffected until the total Redemption Price and any such dividends have been
paid in the manner hereinbefore provided. The Corporation shall have the right
at any time after the sending of notice of its intention to redeem the
Exchangeable Shares as aforesaid to deposit or cause to be deposited the total
Redemption Price for and the full amount of such dividends on (except as
provided in the preceding sentence) the Exchangeable Shares so called for
redemption, or of such of the said Exchangeable Shares represented by
certificates that have not at the date of such deposit been surrendered by the
holders thereof in connection with such redemption, in a custodial account with
any chartered bank or trust company in Canada named in such notice, less any
amounts withheld on account of tax required to be deducted and withheld
therefrom (without interest). Upon the later of such deposit being made and the
Redemption Date, the Exchangeable Shares in respect whereof such deposit shall
have been made shall be redeemed and the rights of the holders thereof after
such deposit or Redemption Date, as the case may be, shall be limited to
receiving their proportionate part of the total Redemption Price and such
dividends for such Exchangeable Shares so deposited (without interest), against
presentation and surrender of the said certificates held by them, respectively,
in accordance with the foregoing provisions. Upon such payment or deposit of the
total Redemption Price and the full amount of such dividends, the holders of the
Exchangeable Shares shall thereafter be considered and deemed for all purposes
to be holders of the Uniphase Common Shares delivered to them or the custodian
on their behalf.

                                   ARTICLE 8
                           PURCHASE FOR CANCELLATION

8.1.  Subject to applicable law and the articles of the Corporation, the
Corporation may at any time and from time to time purchase for cancellation all
or any part of the outstanding Exchangeable Shares at any price by tender to all
the holders of record of Exchangeable Shares then outstanding or through the
facilities of any stock exchange on which the Exchangeable Shares are listed or
quoted at any price per share together with an amount equal to all declared and
unpaid dividends thereon for which the record date has occurred prior to the
date of purchase. If in response to an invitation for tenders under the
provisions of this section 8.1, more Exchangeable Shares are tendered at a price
or prices acceptable to the Corporation than the Corporation is prepared to
purchase, the Exchangeable Shares to be purchased by the Corporation shall be
purchased as nearly as may be PRO RATA according to the number of shares
tendered by each holder who submits a tender to the Corporation, provided that
when shares are tendered at different prices, the pro rating shall be effected
(disregarding fractions) only with respect to the shares tendered at the price
at which more shares were tendered than the Corporation is prepared to purchase
after the Corporation has purchased all the shares tendered at lower prices. If
part only of the Exchangeable Shares represented by any certificate shall be
purchased, a new certificate for the balance of such shares shall be issued at
the expense of the Corporation.

                                   ARTICLE 9
                                 VOTING RIGHTS

9.1.  Except as required by applicable law and by Article 10, section 11.1 and
section 12.2 hereof, the holders of the Exchangeable Shares shall not be
entitled as such to receive notice of or to attend any meeting of the
shareholders of the Corporation or to vote at any such meeting.

                             AMENDMENT AND APPROVAL

10.1. The rights, privileges, restrictions and conditions attaching to the
Exchangeable Shares may be added to, changed or removed but only with the
approval of the holders of the Exchangeable Shares given as hereinafter
specified.

10.2. Any approval given by the holders of the Exchangeable Shares to add to,
change or remove any right, privilege, restriction or condition attaching to the
Exchangeable Shares or any other matter requiring the approval or consent of the
holders of the Exchangeable Shares shall be deemed to have been sufficiently
given if it shall have been given in accordance with applicable law subject to a
minimum requirement that such approval be evidenced by resolution passed by not
less than two-thirds of the votes cast on such resolution at a meeting of
holders of Exchangeable Shares duly called and held at which the holders of at
least 35% of the outstanding Exchangeable Shares at that time are present or
represented by proxy; provided that if at any such meeting the holders of at
least 35% of the outstanding Exchangeable Shares at that time are not present or
represented by proxy within one-half hour after the time appointed for such
meeting, then the meeting shall be adjourned to such date not less than five
days thereafter and to such time and place as may be designated by the Chairman
of such meeting. At such adjourned meeting the holders of Exchangeable Shares
present or represented by proxy thereat may transact the business for which the
meeting was originally called and a resolution passed thereat by the affirmative
vote of not less than two-thirds of the votes cast on such resolution at such
meeting shall constitute the approval or consent of the holders of the
Exchangeable Shares.

                            RECIPROCAL CHANGES, ETC.
                      IN RESPECT OF UNIPHASE COMMON SHARES

11.1. Each holder of an Exchangeable Share acknowledges that the Exchangeable
Share Support Agreement provides, in part, that Uniphase will not without the
prior approval of the Corporation and the prior approval of the holders of the
Exchangeable Shares given in accordance with section 10.2 of these share
provisions:

     (a) issue or distribute Uniphase Common Shares (or securities exchangeable
       for or convertible into or carrying rights to acquire Uniphase Common
       Shares) to the holders of all or substantially all of the then
       outstanding Uniphase Common Shares by way of stock dividend or other
       distribution, other than an issue of Uniphase Common Shares (or
       securities exchangeable for or convertible into or carrying rights to
       acquire Uniphase Common Shares) to holders of Uniphase Common Shares who
       exercise an option to receive dividends in Uniphase Common Shares (or
       securities exchangeable for or convertible into or carrying rights to
       acquire Uniphase Common Shares) in lieu of receiving cash dividends;

     (b) issue or distribute rights, options or warrants to the holders of all
       or substantially all of the then outstanding Uniphase Common Shares
       entitling them to subscribe for or to purchase Uniphase Common Shares (or
       securities exchangeable for or convertible into or carrying rights to
       acquire Uniphase Common Shares); or

     (c) issue or distribute to the holders of all or substantially all of the
       then outstanding Uniphase Common Shares:

        (i) shares or securities of Uniphase of any class other than Uniphase
            Common Shares (other than shares convertible into or exchangeable
            for or carrying rights to acquire Uniphase Common Shares);

        (ii) rights, options or warrants other than those referred to in section
             11.1(b) above;

       (iii) evidences of indebtedness of Uniphase; or

        (iv) assets of Uniphase,

                                      C-32

unless the economic equivalent on a per share basis of such rights, options,
securities, shares, evidences of indebtedness or other assets is issued or
distributed simultaneously to holders of the Exchangeable Shares.

11.2. Each holder of an Exchangeable Share acknowledges that the Exchangeable
Share Support Agreement further provides, in part, that Uniphase will not
without the prior approval of the Corporation and the prior approval of the
holders of the Exchangeable Shares given in accordance with section 10.2 of
these share provisions:

     (a) subdivide, redivide or change the then outstanding Uniphase Common
       Shares into a greater number of Uniphase Common Shares;

     (b) reduce, combine, consolidate or change the then outstanding Uniphase
       Common Shares into a lesser number of Uniphase Common Shares; or

     (c) reclassify or otherwise change the Uniphase Common Shares or effect an
       amalgamation, merger, reorganization or other transaction affecting the
       Uniphase Common Shares,

unless the same or an economically equivalent change shall simultaneously be
made to, or in, the rights of the holders of the Exchangeable Shares. The
Exchangeable Share Support Agreement further provides, in part, that the
aforesaid provisions of the Exchangeable Share Support Agreement shall not be
changed without the approval of the holders of the Exchangeable Shares given in
accordance with section 10.2 of these share provisions.

                                   ARTICLE 12
     ACTIONS BY THE CORPORATION UNDER EXCHANGEABLE SHARE SUPPORT AGREEMENT

12.1. The Corporation will take all such actions and do all such things as shall
be necessary or advisable to perform and comply with and to ensure performance
and compliance by Uniphase, Uniphase Nova Scotia and the Corporation with all
provisions of the Exchangeable Share Support Agreement applicable to Uniphase,
Uniphase Nova Scotia and the Corporation, respectively, in accordance with the
terms thereof including, without limitation, taking all such actions and doing

be valid and effective only if delivered personally to the Corporation in
accordance with section 14.1 or 14.2, as the case may be.

have exercised the Exchange Right (as defined in the Voting and Exchange Trust
Agreement) so as to require Uniphase to purchase the unredeemed Retracted

     So long as any Exchangeable Shares not owned by Uniphase or its Affiliates
are outstanding, Uniphase will:

     (a) not declare or pay any dividend on the Uniphase Common Shares unless
       (i) Exchangeco shall (w) simultaneously declare or pay, as the case may
       be, an equivalent dividend (as provided for in the Share Provisions) on
       the Exchangeable Shares (an "Equivalent Dividend"), and (x) have
       sufficient money or other assets or authorized but unissued securities
       available to enable the due declaration and the due and punctual payment,
       in accordance with applicable law, of any Equivalent Dividend, or (ii)
       Exchangeco shall (y) subdivide the Exchangeable Shares in lieu of a stock
       dividend thereon (as provided for in the Share Provisions) (an
       "Equivalent Stock Subdivision"), and (z) have sufficient authorized but
       unissued securities available to enable the Equivalent Stock Subdivision;

     (b) advise Exchangeco sufficiently in advance of the declaration by
       Uniphase of any dividend on Uniphase Common Shares and take all such
       other actions as are reasonably necessary, in co-operation with
       Exchangeco, to ensure that (i) the respective declaration date, record
       date and payment date for an Equivalent Dividend shall be the same as the
       declaration date, record date and payment date for the corresponding
       dividend on the Uniphase Common Shares or, (ii) the record date and
       effective date for an Equivalent Stock Subdivision shall be the same as
       the record date and payment date for the corresponding stock dividend on
       the Uniphase Common Shares;

     (c) ensure that the record date for any dividend declared on Uniphase
       Common Shares is not less than 10 Business Days after the declaration
       date of such dividend;

     (d) take all such actions and do all such things as are reasonably
       necessary or desirable to enable and permit Exchangeco, in accordance
       with applicable law, to pay and otherwise perform its obligations with
       respect to the satisfaction of the Liquidation Amount, the Retraction
       Price or the Redemption Price in respect of each issued and outstanding
       Exchangeable Share upon the liquidation, dissolution or winding-up of
       Exchangeco, the delivery of a Retraction Request by a holder of
       Exchangeable Shares or a redemption of Exchangeable Shares by Exchangeco,
       as the case may be, including without limitation all such actions and all
       such things as are necessary or desirable to enable and permit Exchangeco
       to cause to be delivered Uniphase Common Shares to the holders of
       Exchangeable Shares in accordance with the provisions of Article 5, 6 or
       7, as the case may be, of the Share Provisions;

                                      D-2

     (e) take all such actions and do all such things as are reasonably
       necessary or desirable to enable and permit Uniphase Nova Scotia, in
       accordance with applicable law, to perform its obligations arising upon
       the exercise by it of the Liquidation Call Right, the Retraction Call
       Right or the Redemption Call Right, including without limitation all such
       actions and all such things as are necessary or desirable to enable and
       permit Uniphase Nova Scotia to cause to be delivered Uniphase Common
       Shares to the holders of Exchangeable Shares in accordance with the
       provisions of the Liquidation Call Right, the Retraction Call Right or
       the Redemption Call Right, as the case may be; and

     (f) if it becomes a "specified financial institution" (as such term is
       defined in the INCOME TAX ACT (Canada) or does not deal at arm's length
       with such a person, take all such actions and do all such things as are
       reasonably necessary or desirable to cause Uniphase Nova Scotia to
       exercise the Retraction Call Right if requested to do so by a holder of
       Exchangeable Shares making a Retraction Request.

2.2.  SEGREGATION OF FUNDS

     Uniphase will cause Exchangeco to deposit a sufficient amount of funds in a
separate account of Exchangeco and segregate a sufficient amount of such other

due and to pay or otherwise satisfy its respective obligations under Article 5,
6 or 7 of the Share Provisions, as applicable.

2.3.  RESERVATION OF UNIPHASE COMMON SHARES

     Uniphase hereby represents, warrants and covenants in favour of Exchangeco

pre-emptive and other rights, out of its authorized and unissued capital stock
such number of Uniphase Common Shares (or other shares or securities into which
Uniphase Common Shares may be reclassified or changed as contemplated by section
2.7 hereof) (a) as is equal to the sum of (i) the number of Exchangeable Shares
issued and outstanding from time to time and (ii) the number of Exchangeable
Shares issuable upon the exercise of all rights to acquire Exchangeable Shares
outstanding from time to time and (b) as are now and may hereafter be required
to enable and permit Uniphase to meet its obligations under the Voting and
Exchange Trust Agreement and under any other security or commitment pursuant to
which Uniphase may now or hereafter be required to issue Uniphase Common Shares,
to enable and permit Uniphase Nova Scotia to meet its obligations under each of
the Liquidation Call Right, the Retraction Call Right and the Redemption Call
Right and to enable and permit Exchangeco to meet its obligations hereunder and
under the Share Provisions.

       effective date of such liquidation, dissolution, winding-up or other
       distribution;

     (b) promptly, upon the earlier of receipt by Exchangeco of notice of and

     In furtherance of its obligations under sections 2.1(d) and (e) hereof,
upon notice from Exchangeco or Uniphase Nova Scotia of any event that requires
Exchangeco or Uniphase Nova Scotia to cause to be delivered Uniphase Common
Shares to any holder of Exchangeable Shares, Uniphase shall forthwith issue and
deliver or cause to be delivered to Exchangeco or Uniphase Nova Scotia the
requisite number of Uniphase Common Shares to be received by, and issued to or
to the order of, the former holder of the surrendered Exchangeable Shares, as
Exchangeco or Uniphase Nova Scotia shall direct. All such Uniphase Common Shares
shall be duly authorized and validly issued as fully paid and non-assessable and
shall be free and clear of any lien, claim or encumbrance. In consideration of
the issuance and delivery of each such Uniphase Common Share, Exchangeco or
Uniphase Nova Scotia, as the case may be, shall issue to Uniphase, or as
Uniphase shall direct, common shares of Exchangeco or Uniphase Nova Scotia
having equivalent value.

2.6.  QUALIFICATION OF UNIPHASE COMMON SHARES

     If any Uniphase Common Shares (or other shares or securities into which
Uniphase Common Shares may be reclassified or changed as contemplated by section
2.7 hereof) to be issued and delivered hereunder require registration or
qualification with or approval of or the filing of any document, including any
prospectus or similar document or the taking of any proceeding with or the
obtaining of any order, ruling or consent from any governmental or regulatory
authority under any Canadian or United States federal, provincial or state
securities or other law or regulation or pursuant to the rules and regulations
of any securities or other regulatory authority or the fulfilment of any other
United States or Canadian legal requirement before such shares (or such other
shares or securities) may be issued by Uniphase and delivered by Uniphase at the
direction of Uniphase Nova Scotia or Exchangeco, if applicable, to the holder of
surrendered Exchangeable Shares or in order that such shares (or such other
shares or securities) may be freely traded thereafter (other than any
restrictions of general application on transfer by reason of a holder being a
"control person" for purposes of Canadian provincial securities law or an
"affiliate" of Uniphase for purposes of United States federal or state
securities law), Uniphase will in good faith expeditiously take all such actions
and do all such things as are necessary or desirable to cause such Uniphase
Common Shares (or such other shares or securities) to be and remain duly
registered, qualified or approved under United States and/or Canadian law, as
the case may be. Uniphase will in good faith expeditiously take all such actions
and do all such things as are reasonably necessary or desirable to cause all
Uniphase Common Shares (or such other shares or securities) to be delivered
hereunder to be listed, quoted or posted for trading on all stock exchanges and
quotation systems on which outstanding Uniphase Common Shares (or such other
shares or securities) have been listed by Uniphase and remain listed and are
quoted or posted for trading at such time.

2.7.  ECONOMIC EQUIVALENCE

       approval of the holders of the Exchangeable Shares given in accordance
       with section 10.2 of the Share Provisions:

        (i) issue or distribute Uniphase Common Shares (or securities
            exchangeable for or convertible into or carrying rights to acquire
            Uniphase Common Shares) to the holders of all or substantially all
            of the then outstanding Uniphase Common Shares by way of stock
            dividend or other distribution, other than an issue of Uniphase
            Common Shares (or securities exchangeable for or convertible into or
            carrying rights to acquire Uniphase Common Shares) to holders of
            Uniphase Common Shares who exercise an option to receive dividends
            in Uniphase Common Shares (or securities exchangeable for or
            convertible into or carrying rights to acquire Uniphase Common
            Shares) in lieu of receiving cash dividends; or

                                      D-4

        (ii) issue or distribute rights, options or warrants to the holders of
             all or substantially all of the then outstanding Uniphase Common
             Shares entitling them to subscribe for or to purchase Uniphase
             Common Shares (or securities exchangeable for or convertible into
             or carrying rights to acquire Uniphase Common Shares); or

       (iii) issue or distribute to the holders of all or substantially all of
             the then outstanding Uniphase Common Shares (A) shares or
             securities of Uniphase of any class other than Uniphase Common
             Shares (other than shares convertible into or exchangeable for or
             carrying rights to acquire Uniphase Common Shares), (B) rights,
             options or warrants other than those referred to in section
             2.7(a)(ii) above, (C) evidences of indebtedness of Uniphase or (D)
             assets of Uniphase,

       unless the economic equivalent on a per share basis of such rights,
       options, securities, shares, evidences of indebtedness or other assets is
       issued or distributed simultaneously to holders of the Exchangeable
       Shares, in which case, for greater certainty, no approval of the holders
       of Exchangeable Shares is required; provided that, for greater certainty,
       the above restrictions shall not apply to any securities issued or
       distributed by Uniphase in order to give effect to and to consummate the
       transactions contemplated by, and in accordance with, the Merger
       Agreement.

     (b) Uniphase will not without the prior approval of Exchangeco and the
       prior approval of the holders of the Exchangeable Shares given in
       accordance with section 10.2 of the Share Provisions:

        (i) subdivide, redivide or change the then outstanding Uniphase Common
            Shares into a greater number of Uniphase Common Shares; or

        (ii) reduce, combine, consolidate or change the then outstanding
             Uniphase Common Shares into a lesser number of Uniphase Common
             Shares; or

       (iii) reclassify or otherwise change Uniphase Common Shares or effect an
             amalgamation, merger, reorganization or other transaction affecting
             Uniphase Common Shares,

       unless the same or an economically equivalent change shall simultaneously
       be made to, or in the rights of the holders of, the Exchangeable Shares,
       in which case, for greater certainty, no approval of the holders of
       Exchangeable Shares is required.

     (c) Uniphase will ensure that the record date for any event referred to in
       section 2.7(a) or 2.7(b) above, or (if no record date is applicable for
       such event) the effective date for any such event, is not less than five
       Business Days after the date on which such event is declared or announced
       by Uniphase (with contemporaneous notification thereof by Uniphase to
       Exchangeco).

     (d) The Board of Directors of Exchangeco shall determine, in good faith and
       in its sole discretion, economic equivalence for the purposes of any
       event referred to in section 2.7(a) or 2.7(b) above and each such
       determination shall be conclusive and binding on Uniphase. In making each
       such determination, the following factors shall, without excluding other
       factors determined by the Board of Directors of Exchangeco to be
       relevant, be considered by the Board of Directors of Exchangeco:

        (i) in the case of any stock dividend or other distribution payable in
            Uniphase Common Shares, the number of such shares issued in
            proportion to the number of Uniphase Common Shares previously
            outstanding;

        (ii) in the case of the issuance or distribution of any rights, options
             or warrants to subscribe for or purchase Uniphase Common Shares (or
             securities exchangeable for or convertible into or carrying rights
             to acquire Uniphase Common Shares), the relationship between the
             exercise price of each such right, option or warrant and the
             current market value (as determined by the Board of Directors of
             Exchangeco in the manner above contemplated) of a Uniphase Common
             Share;

       (iii) in the case of the issuance or distribution of any other form of
             property (including without limitation any shares or securities of
             Uniphase of any class other than Uniphase Common Shares, any
             rights, options or warrants other than those referred to in section
             2.7(d)(ii) above, any evidences of indebtedness of Uniphase or any
             assets of Uniphase), the relationship between the fair market value
             (as determined by the Board of Directors of Exchangeco in the
             manner above

                                      D-5

             contemplated) of such property to be issued or distributed with
             respect to each outstanding Uniphase Common Share and the current
             market value (as determined by the Board of Directors of Exchangeco
             in the manner above contemplated) of a Uniphase Common Share;

        (iv) in the case of any subdivision, redivision or change of the then
             outstanding Uniphase Common Shares into a greater number of
             Uniphase Common Shares or the reduction, combination, consolidation
             or change of the then outstanding Uniphase Common Shares into a
             lesser number of Uniphase Common Shares or any amalgamation,
             merger, reorganization or other transaction affecting Uniphase
             Common Shares, the effect thereof upon the then outstanding
             Uniphase Common Shares; and

        (v) in all such cases, the general taxation consequences of the relevant
            event to holders of Exchangeable Shares to the extent that such
            consequences may differ from the taxation consequences to holders of
            Uniphase Common Shares as a result of differences between taxation
            laws of Canada and the United States (except for any differing
            consequences arising as a result of differing marginal taxation
            rates and without regard to the individual circumstances of holders
            of Exchangeable Shares).

       For purposes of the foregoing determinations, the current market value of
       any security listed and traded or quoted on a securities exchange shall
       be the average of the closing bid and ask prices of such security during
       a period of not less than 20 consecutive trading days ending not more
       than three trading days before the date of determination on the principal
       securities exchange on which such securities are listed and traded or
       quoted; provided, however, that if in the opinion of the Board of
       Directors of Exchangeco the public distribution or trading activity of
       such securities during such period does not create a market which
       reflects the fair market value of such securities, then the current
       market value thereof shall be determined by the Board of Directors of
       Exchangeco, in good faith and in its sole discretion, and provided
       further that any such determination by the Board of Directors of
       Exchangeco shall be conclusive and binding on Uniphase.

     (e) Exchangeco agrees that, to the extent required, upon due notice from
       Uniphase, Exchangeco will use its best efforts to take or cause to be
       taken such steps as may be necessary for the purposes of ensuring that
       appropriate dividends are paid or other distributions are made by
       Exchangeco, or subdivisions, redivisions or changes are made to the
       Exchangeable Shares, in order to implement the required economic
       equivalence with respect to the Uniphase Common Shares and Exchangeable
       Shares as provided for in this section 2.7.

2.8.  TENDER OFFERS

     In the event that a tender offer, share exchange offer, issuer bid,
take-over bid or similar transaction with respect to Uniphase Common Shares (an
"Offer") is proposed by Uniphase or is proposed to Uniphase or its shareholders
and is recommended by the Board of Directors of Uniphase, or is otherwise
effected or to be effected with the consent or approval of the Board of
Directors of Uniphase, and the Exchangeable Shares are not redeemed by
Exchangeco or purchased by Uniphase Nova Scotia pursuant to the Redemption Call
Right, Uniphase will use its reasonable efforts expeditiously and in good faith
to take all such actions and do all such things as are necessary or desirable to
enable and permit holders of Exchangeable Shares to participate in such Offer to
the same extent and on an economically equivalent basis as the holders of
Uniphase Common Shares, without discrimination. Without limiting the generality
of the foregoing, Uniphase will use its reasonable efforts expeditiously and in
good faith to ensure that holders of Exchangeable Shares may participate in all
such Offers without being required to retract Exchangeable Shares as against
Exchangeco (or, if so required, to ensure that any such retraction, shall be
effective only upon, and shall be conditional upon, the closing of the Offer and
only to the extent necessary to tender or deposit to the Offer). Nothing herein
shall affect the rights of Exchangeco to redeem (or Uniphase Nova Scotia to
purchase pursuant to the Redemption Call Right) Exchangeable Shares, as
applicable, in the event of a Uniphase Control Transaction.

                                      D-6

2.9.  OWNERSHIP OF OUTSTANDING SHARES

     Without the prior approval of Exchangeco and the prior approval of the
holders of the Exchangeable Shares given in accordance with section 10.2 of the
Share Provisions, Uniphase covenants and agrees in favour of Exchangeco that, as
long as any outstanding Exchangeable Shares are owned by any person or entity
other than Uniphase or any of its Affiliates, Uniphase will be and remain the
direct or indirect beneficial owner of all issued and outstanding voting shares
in the capital of Exchangeco and Uniphase Nova Scotia.

2.10. UNIPHASE AND AFFILIATES NOT TO VOTE EXCHANGEABLE SHARES

     Uniphase covenants and agrees that it will appoint and cause to be
appointed proxyholders with respect to all Exchangeable Shares held by it and
its Affiliates for the sole purpose of attending each meeting of holders of
Exchangeable Shares in order to be counted as part of the quorum for each such
meeting. Uniphase further covenants and agrees that it will not, and will cause
its Affiliates not to, exercise any voting rights which may be exercisable by
holders of Exchangeable Shares from time to time pursuant to the Share
Provisions or pursuant to the provisions of the CANADA BUSINESS CORPORATIONS ACT
(or any successor or other corporate statute by which Exchangeco may in the
future be governed) with respect to any Exchangeable Shares held by it or by its
Affiliates in respect of any matter considered at any meeting of holders of
Exchangeable Shares.

2.11. RULE 10B-18 PURCHASES

     For greater certainty, nothing contained in this Agreement, including
without limitation the obligations of Uniphase contained in section 2.8 hereof,
shall limit the ability of Uniphase or Exchangeco to make a "Rule 10b-18
Purchase" of Uniphase Common Shares pursuant to Rule 10b-18 of the U.S.
Securities Exchange Act of 1934, as amended, or any successor provisions
thereof.

2.12. STOCK EXCHANGE LISTING

     Uniphase covenants and agrees in favour of Exchangeco that, as long as any
outstanding Exchangeable Shares are owned by any person or entity other than
Uniphase or any of its Affiliates, Uniphase will use its reasonable best efforts
to maintain a listing for such Exchangeable Shares on a Canadian stock exchange.

                                   ARTICLE 3.
                              UNIPHASE SUCCESSORS

3.1.  CERTAIN REQUIREMENTS IN RESPECT OF COMBINATION, ETC.

     Uniphase shall not consummate any transaction (whether by way of
reconstruction, reorganization, consolidation, merger, transfer, sale, lease or
otherwise) whereby all or substantially all of its undertaking, property and
assets would become the property of any other person or, in the case of a
merger, of the continuing corporation resulting therefrom unless, but may do so
if:

     (a) such other person or continuing corporation (the "Uniphase Successor")
       by operation of law, becomes, without more, bound by the terms and
       provisions of this Agreement or, if not so bound, executes, prior to or
       contemporaneously with the consummation of such transaction, an Agreement
       supplemental hereto and such other instruments (if any) as are reasonably
       necessary or advisable to evidence the assumption by the Uniphase
       Successor of liability for all moneys payable and property deliverable
       hereunder and the covenant of such Uniphase Successor to pay and deliver
       or cause to be delivered the same and its Agreement to observe and
       perform all the covenants and obligations of Uniphase under this
       Agreement; and

     (b) such transaction shall be upon such terms and conditions as
       substantially to preserve and not to impair in any material respect any
       of the rights, duties, powers and authorities of the other parties
       hereunder or the holders of Exchangeable Shares.

                                      D-7

3.2.  VESTING OF POWERS IN SUCCESSOR

     Whenever the conditions of section 3.1 have been duly observed and
performed, the parties, if required by section 3.1, shall execute and deliver a
supplemental agreement hereto and thereupon Uniphase Successor shall possess and
from time to time may exercise each and every right and power of Uniphase under
this Agreement in the name of Uniphase or otherwise and any act or proceeding by
any provision of this Agreement required to be done or performed by the Board of
Directors of Uniphase or any officers of Uniphase may be done and performed with
like force and effect by the directors or officers of such Uniphase Successor.

3.3.  WHOLLY-OWNED SUBSIDIARIES

     Nothing herein shall be construed as preventing the amalgamation or merger
of any wholly-owned direct or indirect subsidiary of Uniphase with or into
Uniphase or the winding-up, liquidation or dissolution of any wholly-owned
subsidiary of Uniphase provided that all of the assets of such subsidiary are
transferred to Uniphase or another wholly-owned direct or indirect subsidiary of
Uniphase and any such transactions are expressly permitted by this Article 3.

                                   ARTICLE 4.
                                    GENERAL

4.1.  TERM

     This Agreement shall come into force and be effective as of the date hereof
and shall terminate and be of no further force and effect at such time as no
Exchangeable Shares (or securities or rights convertible into or exchangeable
for or carrying rights to acquire Exchangeable Shares) are held by any person or
entity other than Uniphase and any of its Affiliates.

4.2.  CHANGES IN CAPITAL OF UNIPHASE AND EXCHANGECO

     At all times after the occurrence of any event contemplated pursuant to
sections 2.7 and 2.8 hereof or otherwise, as a result of which either Uniphase
Common Shares or the Exchangeable Shares or both are in any way changed, this
Agreement shall forthwith be amended and modified as necessary in order that it
shall apply with full force and effect, MUTATIS MUTANDIS, to all new securities
into which Uniphase Common Shares or the Exchangeable Shares or both are so
changed and the parties hereto shall execute and deliver an Agreement in writing
giving effect to and evidencing such necessary amendments and modifications.

4.3.  SEVERABILITY

     If any term or other provision of this Agreement is invalid, illegal or
incapable of being enforced by any rule or law, or public policy, all other
conditions and provisions of this Agreement shall nevertheless remain in full
force and effect so long as the economic or legal substance of the transactions
contemplated hereby is not affected in any manner materially adverse to any
party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that the
transactions contemplated hereby are fulfilled to the fullest extent possible.

4.4.  AMENDMENTS, MODIFICATIONS

     This Agreement may not be amended or modified except by an Agreement in
writing executed by Exchangeco, Uniphase Nova Scotia and Uniphase and approved
by the holders of the Exchangeable Shares in accordance with section 10.2 of the

the purposes of:

     (a) adding to the covenants of any or all parties provided that the Board
       of Directors of each of Exchangeco, Uniphase Nova Scotia and Uniphase
       shall be of the good faith opinion that such additions will not be
       prejudicial to the rights or interests of the holders of the Exchangeable
       Shares;

     (b) making such amendments or modifications not inconsistent with this
       Agreement as may be necessary or desirable with respect to matters or
       questions which, in the good faith opinion of the Board of Directors of
       each of Exchangeco, Uniphase Nova Scotia and Uniphase, it may be
       expedient to make, provided that each such Board of Directors shall be of
       the good faith opinion that such amendments or modifications will not be
       prejudicial to the rights or interests of the holders of the Exchangeable
       Shares; or

     (c) making such changes or corrections which, on the advice of counsel to
       Exchangeco, Uniphase Nova Scotia and Uniphase, are required for the
       purpose of curing or correcting any ambiguity or defect or inconsistent
       provision or clerical omission or mistake or manifest error, provided
       that the Boards of Directors of each of Exchangeco, Uniphase Nova Scotia
       and Uniphase shall be of the good faith opinion that such changes or
       corrections will not be prejudicial to the rights or interests of the
       holders of the Exchangeable Shares.

as the Trustee, Uniphase or Exchangeco may reasonably require together with (a)
a duly completed form of notice of exercise of the Exchange Right, contained on
the reverse of or attached to the Exchangeable Share certificates, stating (i)
that the Beneficiary thereby instructs the Trustee to exercise the Exchange
Right so as to require Uniphase to purchase from the Beneficiary the number of
Exchangeable Shares specified therein, (ii) that such Beneficiary has good title
to and owns all such Exchangeable Shares to be acquired by Uniphase free and
clear of all liens, claims, security interests, adverse claims and encumbrances,
(iii) the names in which the certificates representing Uniphase Common Shares
issuable in connection with the exercise of the Exchange Right are to be issued
and (iv) the names and addresses of the persons to whom such new certificates
should be delivered; and (b) payment (or evidence satisfactory to the Trustee,
Exchangeco and Uniphase of payment) of the taxes (if any) payable as
contemplated by section 5.8 of this trust agreement. If only a part of the
Exchangeable Shares represented by any certificate or certificates delivered to
the Trustee are to be purchased by Uniphase under the Exchange Right, a new
certificate for the balance of such Exchangeable Shares shall be issued to the
holder at the expense of Exchangeco.

5.6.  DELIVERY OF UNIPHASE COMMON SHARES; EFFECT OF EXERCISE

     Promptly after receipt of the certificates representing the Exchangeable
Shares which the Beneficiary desires Uniphase to purchase under the Exchange
Right, together with such documents and instruments of transfer and a duly
completed form of notice of exercise of the Exchange Right (and payment of
taxes, if any, payable as contemplated by section 5.8 or evidence thereof), duly
endorsed for transfer to Uniphase, the Trustee shall notify Uniphase and
Exchangeco of its receipt of the same, which notice to Uniphase and Exchangeco
shall constitute exercise of the Exchange Right by the Trustee on behalf of the
holder of such Exchangeable Shares, and Uniphase shall promptly thereafter
deliver or cause to be delivered to the Trustee, for delivery to the Beneficiary
of such Exchangeable Shares (or to such other persons, if any, properly
designated by such Beneficiary) the number of Uniphase Common Shares issuable in
connection with the exercise of the Exchange Right, and on the applicable
payment date cheques for the balance, if any, of the total purchase price
therefor without interest (but less any amounts withheld pursuant to section
5.13); provided, however, that no such delivery shall be made unless and until
the Beneficiary requesting the same shall have paid (or provided

                                      E-9

evidence satisfactory to the Trustee, Exchangeco and Uniphase of the payment of)
the taxes (if any) payable as contemplated by section 5.8 of this trust
agreement. Immediately upon the giving of notice by the Trustee to Uniphase and
Exchangeco of the exercise of the Exchange Right as provided in this section
5.6, the closing of the transaction of purchase and sale contemplated by the
Exchange Right shall be deemed to have occurred and the holder of such
Exchangeable Shares shall be deemed to have transferred to Uniphase all of such
holders' right, title and interest in and to such Exchangeable Shares and the
related interest in the Trust Estate and shall cease to be a holder of such
Exchangeable Shares and shall not be entitled to exercise any of the rights of a
holder in respect thereof, other than the right to receive his proportionate
part of the total purchase price therefor (together with a cheque for the
balance, if any, of the total purchase price therefor without interest), unless
the requisite number of Uniphase Common Shares is not allotted, issued and
delivered by Uniphase to the Trustee within five Business Days of the date of
the giving of such notice by the Trustee, in which case the rights of the
Beneficiary shall remain unaffected until such Uniphase Common Shares are so
allotted, issued and delivered by Uniphase and any such cheque is delivered and
paid. Upon delivery by Uniphase to the Trustee of such Uniphase Common Shares,
the Trustee shall deliver such Uniphase Common Shares to such Beneficiary (or to
such other persons, if any, properly designated by such Beneficiary).
Concurrently with such Beneficiary ceasing to be a holder of Exchangeable
Shares, the Beneficiary shall be considered and deemed for all purposes to be
the holder of the Uniphase Common Shares delivered to it pursuant to the
Exchange Right.

5.7.  EXERCISE OF EXCHANGE RIGHT SUBSEQUENT TO RETRACTION

     In the event that a Beneficiary has exercised its right under Article 6 of
the Share Provisions to require Exchangeco to redeem any or all of the
Exchangeable Shares held by the Beneficiary (the "Retracted Shares") and is
notified by Exchangeco pursuant to section 6.6 of the Share Provisions that
Exchangeco will not be permitted as a result of solvency requirements of
applicable law to redeem all such Retracted Shares, and provided that Uniphase
Nova Scotia shall not have exercised the Retraction Call Right with respect to
the Retracted Shares and that the Beneficiary has not revoked the retraction
request delivered by the Beneficiary to Exchangeco pursuant to section 6.1 of
the Share Provisions, the retraction request will constitute and will be deemed
to constitute notice from the Beneficiary to the Trustee instructing the Trustee
to exercise the Exchange Right with respect to those Retracted Shares that
Exchangeco is unable to redeem. In any such event, Exchangeco hereby agrees with
the Trustee and in favour of the Beneficiary to immediately notify the Trustee
of such prohibition against Exchangeco redeeming all of the Retracted Shares and
to promptly forward or cause to be forwarded to the Trustee all relevant
materials delivered by the Beneficiary to Exchangeco or to the transfer agent of
the Exchangeable Shares (including without limitation, a copy of the retraction
request delivered pursuant to section 6.1 of the Share Provisions) in connection
with such proposed redemption of the Retracted Shares and the Trustee will
thereupon exercise the Exchange Right with respect to the Retracted Shares that
Exchangeco is not permitted to redeem and will require Uniphase to purchase such
shares in accordance with the provisions of this Article 5.

5.8.  STAMP OR OTHER TRANSFER TAXES

     Upon any sale of Exchangeable Shares to Uniphase pursuant to the Exchange
Right or the Automatic Exchange Rights, the share certificate or certificates
representing Uniphase Common Shares to be delivered in connection with the
payment of the total purchase price therefor shall be issued in the name of the
Beneficiary of the Exchangeable Shares so sold or in such names as such
Beneficiary may otherwise direct in writing without charge to the holder of the
Exchangeable Shares so sold; provided, however, that such Beneficiary (a) shall
pay (and none of Uniphase, Exchangeco or the Trustee shall be required to pay)
any documentary, stamp, transfer or other taxes that may be payable in respect
of any transfer involved in the issuance or delivery of such shares to a person
other than such Beneficiary or (b) shall have evidenced to the satisfaction of
the Trustee, Uniphase and Exchangeco that such taxes, if any, have been paid.

5.9.  NOTICE OF INSOLVENCY EVENT

     As soon as practicable following the occurrence of an Insolvency Event or
any event that with the giving of notice or the passage of time or both would be
an Insolvency Event, Exchangeco and Uniphase shall give written notice thereof
to the Trustee. As soon as practicable following the receipt of notice from
Exchangeco or

                                      E-10

Uniphase of the occurrence of an Insolvency Event, or upon the Trustee becoming
aware of an Insolvency Event, the Trustee will mail to each Beneficiary, at the
expense of Uniphase, a notice of such Insolvency Event in the form provided by
Uniphase, which notice shall contain a brief statement of the rights of the
Beneficiaries with respect to the Exchange Right.

5.10. QUALIFICATION OF UNIPHASE COMMON SHARES

     Uniphase covenants that if any Uniphase Common Shares to be issued and
delivered pursuant to the Exchange Right or the Automatic Exchange Rights
require registration or qualification with or approval of or the filing of any
document, including any prospectus or similar document, or the taking of any
proceeding with or the obtaining of any order, ruling or consent from any
governmental or regulatory authority under any Canadian or United States
federal, provincial or state law or regulation or pursuant to the rules and
regulations of any regulatory authority or the fulfilment of any other Canadian
or United States federal, provincial or state legal requirement before such
shares may be issued and delivered by Uniphase to the initial holder thereof or
in order that such shares may be freely traded thereafter (other than any
restrictions of general application on transfer by reason of a holder being a
"control person" of Uniphase for purposes of Canadian provincial securities law
or an "affiliate" of Uniphase for purposes of United States federal or state
securities law), Uniphase will in good faith expeditiously take all such actions
and do all such things as are necessary or desirable to cause such Uniphase
Common Shares to be and remain duly registered, qualified or approved. Uniphase
will in good faith expeditiously take all such actions and do all such things as
are reasonably necessary or desirable to cause all Uniphase Common Shares to be
delivered pursuant to the Exchange Right or the Automatic Exchange Rights to be
listed, quoted or posted for trading on all stock exchanges and quotation
systems on which outstanding Uniphase Common Shares have been listed by Uniphase
and remain listed and are quoted or posted for trading at such time.

5.11. UNIPHASE COMMON SHARES

     Uniphase hereby represents, warrants and covenants that the Uniphase Common
Shares issuable as described herein will be duly authorized and validly issued
as fully paid and non-assessable and shall be free and clear of any lien, claim
or encumbrance.

5.12. AUTOMATIC EXCHANGE ON LIQUIDATION OF UNIPHASE

     (a) Uniphase will give the Trustee written notice of each of the following
       events at the time set forth below:

        (i) in the event of any determination by the Board of Directors of
            Uniphase to institute voluntary liquidation, dissolution or
            winding-up proceedings with respect to Uniphase or to effect any
            other distribution of assets of Uniphase among its shareholders for
            the purpose of winding up its affairs, at least 60 days prior to the
            proposed effective date of such liquidation, dissolution, winding-up
            or other distribution; and

        (ii) as soon as practicable following the earlier of (A) receipt by
             Uniphase of notice of, and (B) Uniphase otherwise becoming aware
             of, any threatened or instituted claim, suit, petition or other
             proceedings with respect to the involuntary liquidation,
             dissolution or winding-up of Uniphase or to effect any other
             distribution of assets of Uniphase among its shareholders for the
             purpose of winding up its affairs, in each case where Uniphase has
             failed to contest in good faith any such proceeding commenced in
             respect of Uniphase within 30 days of becoming aware thereof.

     (b) As soon as practicable following receipt by the Trustee from Uniphase
       of notice of any event (a "Liquidation Event") contemplated by section
       5.12(a)(i) or 5.12(a)(ii) above, the Trustee will give notice thereof to
       the Beneficiaries. Such notice shall be provided by Uniphase to the
       Trustee and shall include a brief description of the automatic exchange
       of Exchangeable Shares for Uniphase Common Shares provided for in section
       5.12(c).

                                      E-11

     (c) In order that the Beneficiaries will be able to participate on a PRO
       RATA basis with the holders of Uniphase Common Shares in the distribution
       of assets of Uniphase in connection with a Liquidation Event, on the
       fifth Business Day prior to the effective date (the "Liquidation Event
       Effective Date") of a Liquidation Event all of the then outstanding
       Exchangeable Shares shall be automatically exchanged for Uniphase Common
       Shares. To effect such automatic exchange, Uniphase shall purchase on the
       fifth Business Day prior to the Liquidation Event Effective Date each
       Exchangeable Share then outstanding and held by Beneficiaries, and each
       Beneficiary shall sell the Exchangeable Shares held by it at such time,
       for a total purchase price per share equal to (a) the Current Market
       Price of a Uniphase Common Share on the fifth Business Day prior to the
       Liquidation Event Effective Date, which shall be satisfied in full by
       Uniphase issuing to the Beneficiary one Uniphase Common Share, and (b) to
       the extent not paid by Exchangeco, an additional amount equivalent to the
       full amount of all declared and unpaid dividends on each such
       Exchangeable Share held by such holder on any dividend record date which
       occurred prior to the date of the exchange. In connection with such
       automatic exchange, Uniphase shall provide to the Trustee an Officer's
       Certificate setting forth the calculation of the purchase price for each
       Exchangeable Share.

     (d) On the fifth Business Day prior to the Liquidation Event Effective
       Date, the closing of the transaction of purchase and sale contemplated by
       the automatic exchange of Exchangeable Shares for Uniphase Common Shares
       shall be deemed to have occurred, and each Beneficiary shall be deemed to
       have transferred to Uniphase all of the Beneficiary's right, title and
       interest in and to such Beneficiary's Exchangeable Shares and the related
       interest in the Trust Estate and shall cease to be a holder of such
       Exchangeable Shares and Uniphase shall issue to the Beneficiary the
       Uniphase Common Shares issuable upon the automatic exchange of
       Exchangeable Shares for Uniphase Common Shares and on the applicable
       payment date shall deliver to the Trustee for delivery to the Beneficiary
       a cheque for the balance, if any, of the total purchase price for such
       Exchangeable Shares without interest but less any amounts withheld
       pursuant to section 5.13. Concurrently with such Beneficiary ceasing to
       be a holder of Exchangeable Shares, the Beneficiary shall be considered
       and deemed for all purposes to be the holder of the Uniphase Common
       Shares issued pursuant to the automatic exchange of Exchangeable Shares
       for Uniphase Common Shares and the certificates held by the Beneficiary
       previously representing the Exchangeable Shares exchanged by the
       Beneficiary with Uniphase pursuant to such automatic exchange shall
       thereafter be deemed to represent Uniphase Common Shares issued to the
       Beneficiary by Uniphase pursuant to such automatic exchange. Upon the
       request of a Beneficiary and the surrender by the Beneficiary of
       Exchangeable Share certificates deemed to represent Uniphase Common
       Shares, duly endorsed in blank and accompanied by such instruments of
       transfer as Uniphase may reasonably require, Uniphase shall deliver or
       cause to be delivered to the Beneficiary certificates representing
       Uniphase Common Shares of which the Beneficiary is the holder.

5.13. WITHHOLDING RIGHTS

     Uniphase, Exchangeco and the Trustee shall be entitled to deduct and
withhold from any consideration otherwise payable under this trust agreement to
any holder of Exchangeable Shares or Uniphase Common Shares such amounts as
Uniphase, Exchangeco or the Trustee is required or permitted to deduct and
withhold with respect to such payment under the INCOME TAX ACT (Canada), the
United States Internal Revenue Code of 1986 or any provision of provincial,
state, local or foreign tax law, in each case as amended or succeeded. To the
extent that amounts are so withheld, such withheld amounts shall be treated for
all purposes as having been paid to the holder of the shares in respect of which
such deduction and withholding was made, provided that such withheld amounts are
actually remitted to the appropriate taxing authority. To the extent that the
amounts so required or permitted to be deducted or withheld from any payment to
a holder exceeds the cash portion of the consideration otherwise payable to the
holder, Uniphase, Exchangeco and the Trustee are hereby authorized to sell or
otherwise dispose of such portion of the consideration as is necessary to
provide sufficient funds to Uniphase, Exchangeco or the Trustee, as the case may
be, to enable it to comply with such deduction or withholding requirements and
Uniphase, Exchangeco or the Trustee shall notify the holder thereof and remit to
such holder any unapplied balance of the net proceeds of such sale. Uniphase
represents and warrants that, based upon facts currently known to it, it has no
current intention, as at the date of this trust agreement, to

                                      E-12

deduct or withhold from any dividend paid to holders of Exchangeable Shares any
amounts under the United States Internal Revenue Code of 1986.

special voting stock in addition to the Uniphase Special Voting Share.

                             CONCERNING THE TRUSTEE

agreement, in its capacity as Trustee of the Trust, shall include:

     (a) receipt and deposit of the Uniphase Special Voting Share from Uniphase
       as Trustee for and on behalf of the Beneficiaries in accordance with the
       provisions of this trust agreement;

     (b) granting proxies and distributing materials to Beneficiaries as
       provided in this trust agreement;

     (c) voting the Beneficiary Votes in accordance with the provisions of this
       trust agreement;

     (d) receiving the grant of the Exchange Right and the Automatic Exchange
       Rights from Uniphase as Trustee for and on behalf of the Beneficiaries in
       accordance with the provisions of this trust agreement;

     (e) exercising the Exchange Right and enforcing the benefit of the
       Automatic Exchange Rights, in each case in accordance with the provisions
       of this trust agreement, and in connection therewith receiving from
       Beneficiaries Exchangeable Shares and other requisite documents and
       distributing to such Beneficiaries Uniphase Common Shares and cheques, if
       any, to which such Beneficiaries are entitled upon the exercise of the
       Exchange Right or pursuant to the Automatic Exchange Rights, as the case
       may be;

     (f) holding title to the Trust Estate;

     (g) investing any moneys forming, from time to time, a part of the Trust
       Estate as provided in this trust agreement;

     (h) taking action at the direction of a Beneficiary or Beneficiaries to
       enforce the obligations of Uniphase and Exchangeco under this trust
       agreement; and

     (i) taking such other actions and doing such other things as are
       specifically provided in this trust agreement.

     In the exercise of such rights, powers, duties and authorities the Trustee
shall have (and is granted) such incidental and additional rights, powers,
duties and authority not in conflict with any of the provisions of this trust
agreement as the Trustee, acting in good faith and in the reasonable exercise of
its discretion, may deem necessary, appropriate or desirable to effect the
purpose of the Trust. Any exercise of such discretionary rights, powers, duties
and authorities by the Trustee shall be final, conclusive and binding upon all
persons.

7.2.  NO CONFLICT OF INTEREST

     The Trustee represents to Uniphase and Exchangeco that at the date of
execution and delivery of this trust agreement there exists no material conflict
of interest in the role of the Trustee as a fiduciary hereunder and the role of
the Trustee in any other capacity. The Trustee shall, within 90 days after it
becomes aware that such material conflict of interest exists, either eliminate
such material conflict of interest or resign in the manner and with the effect
specified in Article 10. If, notwithstanding the foregoing provisions of this
section 7.2, the Trustee has such a material conflict of interest, the validity
and enforceability of this trust agreement shall not be affected in any manner
whatsoever by reason only of the existence of such material conflict of
interest. If the Trustee contravenes the foregoing provisions of this section
7.2, any interested party may apply to the Ontario Superior Court of Justice for
an order that the Trustee be replaced as Trustee hereunder.

7.3.  DEALINGS WITH TRANSFER AGENTS, REGISTRARS, ETC.

     Uniphase and Exchangeco irrevocably authorize the Trustee, from time to
time, to:

     (a) consult, communicate and otherwise deal with the respective registrars
       and transfer agents, and with any such subsequent registrar or transfer
       agent, of the Exchangeable Shares and Uniphase Common Shares; and

     (b) requisition, from time to time, (i) from any such registrar or transfer
       agent any information readily available from the records maintained by it
       which the Trustee may reasonably require for the discharge of its duties
       and responsibilities under this trust agreement and (ii) from the
       transfer agent of Uniphase Common Shares, and any subsequent transfer
       agent of such shares, the share certificates issuable upon the exercise
       from time to time of the Exchange Right and pursuant to the Automatic
       Exchange Rights in the manner specified in Article 5 hereof.

     Uniphase and Exchangeco irrevocably authorize their respective registrars
and transfer agents to comply with all such requests. Uniphase covenants that it
will supply its transfer agent with duly executed share certificates for the

the Automatic Exchange Rights in each case pursuant to Article 5 hereof.

and records of account relating to the Trust created by this trust agreement,
including without limitation, all relevant data relating to mailings and
instructions to and from Beneficiaries and all transactions pursuant to the
Exchange Right and the Automatic Exchange Rights. On or before September 30,
2000 and on or before September 30 in every year thereafter, so long as the
Uniphase Special Voting Share is on deposit with the Trustee, the Trustee shall

June 30, with respect to:

     (a) the property and funds comprising the Trust Estate as of that date;

     (b) the number of exercises of the Exchange Right, if any, and the

       of Beneficiaries in consideration of the issuance by Uniphase of Uniphase
       Common Shares in connection with the Exchange Right, during the fiscal
       year ended on such June 30; and

prepared and filed on behalf of the Trust appropriate United States and Canadian
income tax returns and any other returns or reports as may be required by
applicable law or pursuant to the rules and regulations of any securities
exchange or other trading system through which the Exchangeable Shares are
traded and in connection therewith may obtain the advice of

                                      E-14

necessary or advisable. If requested by the Trustee, Uniphase shall retain such
experts for providing such advice or assistance to the Trustee.

7.6.  INDEMNIFICATION PRIOR TO CERTAIN ACTIONS BY TRUSTEE

     The Trustee shall exercise any or all of the rights, duties, powers or
authorities vested in it by this trust agreement at the request, order or
direction of any Beneficiary upon such Beneficiary furnishing to the Trustee
reasonable funding, security or indemnity against the costs, expenses and
liabilities which may be incurred by the Trustee therein or thereby, provided
that no Beneficiary shall be obligated to furnish to the Trustee any such
funding, security or indemnity in connection with the exercise by the Trustee of
any of its rights, duties, powers and authorities with respect to the Uniphase
Special Voting Share pursuant to Article 4, subject to section 7.15, and with
respect to the Exchange Right pursuant to Article 5, subject to section 7.15,
and with respect to the Automatic Exchange Rights pursuant to Article 5, subject

Trustee to expend or risk its own funds or otherwise incur financial liability
in the exercise of any of its rights, powers, duties, or authorities unless
funded, given security or indemnified as aforesaid.

7.7.  ACTION OF BENEFICIARIES

     No Beneficiary shall have the right to institute any action, suit or
proceeding or to exercise any other remedy authorized by this trust agreement
for the purpose of enforcing any of its rights or for the execution of any trust
or power hereunder unless the Beneficiary has requested the Trustee to take or
institute such action, suit or proceeding and furnished the Trustee with the
funds, security or indemnity referred to in section 7.6 and the Trustee shall
have failed to act within a reasonable time thereafter. In such case, but not
otherwise, the Beneficiary shall be entitled to take proceedings in any court of
competent jurisdiction such as the Trustee might have taken; it being understood
and intended that no one or more Beneficiaries shall have any right in any
manner whatsoever to affect, disturb or prejudice the rights hereby created by
any such action, or to enforce any right hereunder or the Voting Rights, the
Exchange Rights or the Automatic Exchange Rights, except subject to the
conditions and in the manner herein provided, and that all powers and trusts
hereunder shall be exercised and all proceedings at law shall be instituted, had
and maintained by the Trustee, except only as herein provided, and in any event
for the equal benefit of all Beneficiaries.

rights, powers, duties and authorities hereunder if, when required, it acts and
relies in good faith upon statutory declarations, certificates, opinions, Lists,
mailing labels, reports or other papers or documents furnished pursuant to the
provisions hereof or required by the Trustee to be furnished to it in the
exercise of its rights, powers, duties and authorities hereunder if such
statutory declarations, certificates, opinions, Lists, mailing labels, reports
or other papers or documents comply with the provisions of section 7.9, if
applicable, and with any other applicable provisions of this trust agreement.

7.9.  EVIDENCE AND AUTHORITY TO TRUSTEE

     Uniphase and/or Exchangeco shall furnish to the Trustee evidence of
compliance with the conditions provided for in this trust agreement relating to
any action or step required or permitted to be taken by Uniphase and/or

respect of the Voting Rights or the Exchange Right or the Automatic Exchange
Rights and the taking of any other action to be taken by the Trustee at the
request of or on the application of Uniphase and/or Exchangeco promptly if and
when:

     (a) such evidence is required by any other section of this trust agreement
       to be furnished to the Trustee in accordance with the terms of this
       section 7.9; or

                                      E-15

     (b) the Trustee, in the exercise of its rights, powers, duties and
       authorities under this trust agreement, gives Uniphase and/or Exchangeco
       written notice requiring it to furnish such evidence in relation to any
       particular action or obligation specified in such notice.

     Such evidence shall consist of an Officer's Certificate of Uniphase and/or
Exchangeco or a statutory declaration or a certificate made by persons entitled
to sign an Officer's Certificate stating that any such condition has been
complied with in accordance with the terms of this trust agreement.

     Whenever such evidence relates to a matter other than the Voting Rights or
the Exchange Right or the Automatic Exchange Rights or the taking of any other
action to be taken by the Trustee at the request or on the application of
Uniphase and/or Exchangeco, and except as otherwise specifically provided
herein, such evidence may consist of a report or opinion of any solicitor,

Certificate or a statutory declaration.

     Each statutory declaration, Officer's Certificate, opinion or report
furnished to the Trustee as evidence of compliance with a condition provided for

evidence:

     (a) declaring that he has read and understands the provisions of this trust
       agreement relating to the condition in question;

     (b) describing the nature and scope of the examination or investigation
       upon which he based the statutory declaration, certificate, statement or
       opinion; and

     (c) declaring that he has made such examination or investigation as he
       believes is necessary to enable him to make the statements or give the
       opinions contained or expressed therein.

become so authorized or resign in the manner and with the effect specified in
Article 10.

7.15. CONFLICTING CLAIMS

     If conflicting claims or demands are made or asserted with respect to any
interest of any Beneficiary in any Exchangeable Shares, including any
disagreement between the heirs, representatives, successors or assigns
succeeding to all or any part of the interest of any Beneficiary in any
Exchangeable Shares, resulting in conflicting claims or demands being made in
connection with such interest, then the Trustee shall be entitled, at its sole
discretion, to refuse to recognize or to comply with any such claims or demands.
In so refusing, the Trustee may elect not to exercise any Voting Rights,
Exchange Rights or Automatic Exchange Rights subject to such conflicting claims
or demands and, in so doing, the Trustee shall not be or become liable to any
person on account of such election or its failure or refusal to comply with any
such conflicting claims or demands. The Trustee shall be entitled to continue to
refrain from acting and to refuse to act until:

     (a) the rights of all adverse claimants with respect to the Voting Rights,
       Exchange Right or Automatic Exchange Rights subject to such conflicting
       claims or demands have been adjudicated by a final judgment of a court of
       competent jurisdiction and all rights of appeal have expired; or

     (b) all differences with respect to the Voting Rights, Exchange Right or
       Automatic Exchange Rights subject to such conflicting claims or demands
       have been conclusively settled by a valid written agreement binding on
       all such adverse claimants, and the Trustee shall have been furnished
       with an executed copy of such agreement certified to be in full force and
       effect.

     If the Trustee elects to recognize any claim or comply with any demand made
by any such adverse claimant, it may in its discretion require such claimant to
furnish such surety bond or other security satisfactory to the Trustee as it
shall deem appropriate to fully indemnify it as between all conflicting claims
or demands.

7.16. ACCEPTANCE OF TRUST

     The Trustee hereby accepts the Trust created and provided for by and in

to time be Beneficiaries, subject to all the terms and conditions herein set
forth.

                                  COMPENSATION

8.1.  FEES AND EXPENSES OF THE TRUSTEE

     Uniphase and Exchangeco jointly and severally agree to pay the Trustee
reasonable compensation for all of the services rendered by it under this trust
agreement and will reimburse the Trustee for all reasonable expenses (including
but not limited to taxes other than taxes based on the net income of the
Trustee, compensation paid to experts and advisers, and travel expenses) and
disbursements, including the cost and expense of any suit or litigation of any
character and any proceedings before any governmental agency reasonably incurred
by the Trustee in connection with its duties under this trust agreement;
provided that Uniphase and Exchangeco shall have no obligation to reimburse the
Trustee for any expenses or disbursements paid, incurred or suffered by the
Trustee in any suit or litigation in which the Trustee is determined to have
acted in bad faith or with negligence, recklessness or wilful misconduct.

                                   ARTICLE 9
                  INDEMNIFICATION AND LIMITATION OF LIABILITY

9.1.  INDEMNIFICATION OF THE TRUSTEE

     Uniphase and Exchangeco jointly and severally agree to indemnify and hold
harmless the Trustee and each of its directors, officers, employees and agents
appointed and acting in accordance with this trust agreement (collectively, the
"Indemnified Parties") against all claims, losses, damages, reasonable costs,
penalties, fines and reasonable expenses (including reasonable expenses of the
Trustee's legal counsel) which, without fraud, negligence, recklessness, wilful
misconduct or bad faith on the part of such Indemnified Party, may be paid,
incurred or suffered by the Indemnified Party by reason or as a result of the
Trustee's acceptance or administration of the Trust, its compliance with its
duties set forth in this trust agreement, or any written or oral instruction (to
be confirmed in writing) delivered to the Trustee by Uniphase or Exchangeco
pursuant hereto.

     In no case shall Uniphase or Exchangeco be liable under this indemnity for
any claim against any of the Indemnified Parties unless Uniphase and Exchangeco
shall be notified by the Trustee of the written assertion of a claim or of any
action commenced against the Indemnified Parties, promptly after any of the
Indemnified Parties shall have received any such written assertion of a claim or
shall have been served with a summons or other first legal process giving
information as to the nature and basis of the claim. Subject to (ii) below,
Uniphase and Exchangeco shall be entitled to participate at their own expense in
the defence and, if Uniphase and Exchangeco so elect at any time after receipt
of such notice, either of them may assume the defence of any suit brought to
enforce any such claim. The Trustee shall have the right to employ separate
counsel in any such suit and participate in the defence thereof but the fees and
expenses of such counsel shall be at the expense of the Trustee unless: (i) the
employment of such counsel has been authorized by Uniphase or Exchangeco, such
authorization not to be unreasonably withheld; or (ii) the named parties to any
such suit include both the Trustee and Uniphase or Exchangeco and the Trustee
shall have been advised by counsel acceptable to Uniphase or Exchangeco that
there may be one or more legal defences available to the Trustee that are
different from or in addition to those available to Uniphase or Exchangeco and
that, in the judgment of such counsel, would present a conflict of interest were
a joint representation to be undertaken (in which case Uniphase and Exchangeco
shall not have the right to assume the defence of such suit on behalf of the
Trustee but shall be liable to pay the reasonable fees and expenses of counsel
for the Trustee). This indemnity shall survive the resignation or removal of the
trustee and the termination of the Trust.

9.2.  LIMITATION OF LIABILITY

     The Trustee shall not be held liable for any loss which may occur by reason
of depreciation of the value of any part of the Trust Estate or any loss
incurred on any investment of funds pursuant to this trust agreement, except to
the extent that such loss is attributable to the fraud, negligence,
recklessness, wilful misconduct or bad faith on the part of the Trustee.

10.1. RESIGNATION

     The Trustee, or any trustee hereafter appointed, may at any time resign by
giving written notice of such resignation to Uniphase and Exchangeco specifying
the date on which it desires to resign, provided that such notice shall not be
given less than one month before such desired resignation date unless Uniphase
and Exchangeco otherwise agree and provided further that such resignation shall
not take effect until the date of the appointment of a successor trustee and the
acceptance of such appointment by the successor trustee. Upon receiving such
notice of resignation, Uniphase and Exchangeco shall promptly appoint a
successor trustee by written instrument in duplicate, one copy of which shall be
delivered to the resigning trustee and one copy to the successor trustee.
Failing appointment of a successor trustee by Uniphase and Exchangeco, a
successor trustee may be appointed by an order of the Ontario Superior Court of
Justice upon application of one or more parties hereto. Should the retiring
trustee apply for the appointment of a successor trustee by an order of the
Ontario Superior Court of Justice it shall be at the joint and several expense
of Uniphase and Exchangeco.

10.2. REMOVAL

     The Trustee, or any trustee hereafter appointed, may (provided a successor
trustee is appointed) be removed at any time on not less than 30 days' prior
notice by written instrument executed by Uniphase and Exchangeco, in duplicate,
one copy of which shall be delivered to the trustee so removed and one copy to
the successor trustee.

10.3. SUCCESSOR TRUSTEE

     Any successor trustee appointed as provided under this trust agreement
shall execute, acknowledge and deliver to Uniphase and Exchangeco and to its
predecessor trustee an instrument accepting such appointment. Thereupon the
resignation or removal of the predecessor trustee shall become effective and
such successor trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, duties and obligations of its
predecessor under this trust agreement, with the like effect as if originally
named as trustee in this trust agreement. However, on the written request of
Uniphase and Exchangeco or of the successor trustee, the trustee ceasing to act
shall, upon payment of any amounts then due it pursuant to the provisions of
this trust agreement, execute and deliver an instrument transferring to such
successor trustee all the rights and powers of the trustee so ceasing to act.
Upon the request of any such successor trustee, Uniphase, Exchangeco and such
predecessor trustee shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor trustee all such
rights and powers.

10.4. NOTICE OF SUCCESSOR TRUSTEE

     Upon acceptance of appointment by a successor trustee as provided herein,
Uniphase and Exchangeco shall cause to be mailed notice of the succession of
such trustee hereunder to each Beneficiary specified in a List. If Uniphase or
Exchangeco shall fail to cause such notice to be mailed within 10 days after
acceptance of appointment by the successor trustee, the successor trustee shall
cause such notice to be mailed at the expense of Uniphase and Exchangeco.

11.1. CERTAIN REQUIREMENTS IN RESPECT OF COMBINATION, ETC.

     Uniphase shall not consummate any transaction (whether by way of
reconstruction, reorganization, consolidation, merger, transfer, sale, lease or
otherwise) whereby all or substantially all of its undertaking,

                                      E-19

property and assets would become the property of any other person or, in the
case of a merger, of the continuing corporation resulting therefrom unless, but
may do so if:

     (a) such other person or continuing corporation (herein called the
       "Uniphase Successor"), by operation of law, becomes, without more, bound
       by the terms and provisions of this trust agreement or, if not so bound,
       executes, prior to or contemporaneously with the consummation of such
       transaction, a trust agreement supplemental hereto and such other
       instruments (if any) as are satisfactory to the Trustee, acting
       reasonably, and in the opinion of legal counsel to the Trustee are
       reasonably necessary or advisable to evidence the assumption by the
       Uniphase Successor of liability for all moneys payable and property
       deliverable hereunder and the covenant of such Uniphase Successor to pay
       and deliver or cause to be delivered the same and its agreement to
       observe and perform all the covenants and obligations of Uniphase under
       this trust agreement; and

     (b) such transaction shall, to the satisfaction of the Trustee, acting
       reasonably, and in the opinion of legal counsel to the Trustee, be upon
       such terms and conditions as substantially to preserve and not to impair
       in any material respect any of the rights, duties, powers and authorities
       of the Trustee or of the Beneficiaries hereunder.

11.2. VESTING OF POWERS IN SUCCESSOR

     Whenever the conditions of section 11.1 have been duly observed and
performed, the Trustee and, if required by section 11.1, Uniphase Successor and
Exchangeco shall execute and deliver the supplemental trust agreement provided
for in Article 12 and thereupon Uniphase Successor shall possess and from time
to time may exercise each and every right and power of Uniphase under this trust
agreement in the name of Uniphase or otherwise and any act or proceeding by any
provision of this trust agreement required to be done or performed by the Board
of Directors of Uniphase or any officers of Uniphase may be done and performed
with like force and effect by the directors or officers of such Uniphase
Successor.

11.3. WHOLLY-OWNED SUBSIDIARIES

     Nothing herein shall be construed as preventing the amalgamation or merger
of any wholly-owned direct or indirect subsidiary of Uniphase with or into
Uniphase or the winding-up, liquidation or dissolution of any wholly-owned
subsidiary of Uniphase provided that all of the assets of such subsidiary are
transferred to Uniphase or another wholly-owned direct or indirect subsidiary of
Uniphase and any such transactions are expressly permitted by this Article 11.

       of the Beneficiaries hereunder provided that the Board of Directors of

       Beneficiaries;

       trust agreement as may be necessary or desirable with respect to matters
       or questions which, in the good faith opinion of the Board of Directors

       Trustee,

                                      E-20

       having in mind the best interests of the Beneficiaries, it may be
       expedient to make, provided that such Boards of Directors shall be of the
       opinion that such amendments and modifications will not be prejudicial to
       the interests of the Beneficiaries; or

     (c) making such changes or corrections which, on the advice of counsel to
       Uniphase, Exchangeco and the Trustee, are required for the purpose of

section 2.7 or 2.8 of the Support Agreement or otherwise, as a result of which

changed, this trust agreement shall forthwith be amended and modified as
necessary in order that it shall apply with full force and effect, MUTATIS
MUTANDIS, to all new securities into which Uniphase Common Shares or the
Exchangeable Shares or both are so changed and the parties hereto shall execute
and deliver a supplemental trust agreement giving effect to and evidencing such
necessary amendments and modifications.

       Trustee, necessary or advisable in order to incorporate, reflect or
       comply with any legislation the provisions of which apply to Uniphase,
       Exchangeco, the Trustee or this trust agreement; and

     (c) for any other purposes not inconsistent with the provisions of this

                         UNIPHASE TRANSACTION PROPOSAL

     On January 28, 1999, Uniphase Corporation ("Uniphase"), 3506967 Canada Inc.
("Exchangeco"), a newly formed Canadian subsidiary of Uniphase, and JDS FITEL
Inc. ("JDS"), entered into a merger agreement which was amended and restated as
of April 29, 1999 (the "Merger Agreement"), pursuant to which JDS will be
combined with Uniphase (the "Transaction"). Pursuant to the Merger Agreement,
each holder of outstanding common shares of JDS ("JDS Common Shares") will
receive as consideration for each JDS Common Share, subject to certain
conditions, either (a) 0.50855 of a share of common stock of Uniphase (a
"Uniphase Common Share"), or (b) 0.50855 of a share of a new class of stock of

Board of Directors
Uniphase Corporation

163 Baypointe Parkway

San Jose, CA 95134

Dear Members of the Board:

     Uniphase Corporation, a Delaware corporation ("Uniphase"), Uniphase
Exchangeco (Canada), a Canadian corporation and an indirect wholly-owned
subsidiary of Uniphase ("Exchangeco"), and JDS FITEL Inc., a Canadian
corporation ("JDS FITEL"), have entered into a Merger Agreement dated as of
January 28, 1999 (the "Agreement") providing for the proposed combination of
Uniphase and JDS FITEL (the "Merger"). The Agreement provides, among other
things, that pursuant to the terms of a Plan of Arrangement under Section 192 of
the Canada Business Corporations Act (the "Plan of Arrangement"), JDS FITEL will
become an indirect wholly-owned subsidiary of Uniphase and shareholders of JDS
FITEL will receive, in exchange for each share of common stock of JDS FITEL
issued and outstanding immediately prior to the Effective Time (as defined in
the Agreement), subject to the terms of the Agreement, that number of shares of
common stock of Uniphase or that number of exchangeable shares of Exchangeco,
equal to the Exchange Ratio (as such term is defined in the Plan of Arrangement)
(the right to receive the applicable number of shares of common stock of
Uniphase or of exchangeable shares of Exchangeco being referred to herein as the
"Exchange Consideration"). You have requested our opinion as to whether the
Exchange Consideration to be paid by Uniphase to the holders of common stock of
JDS FITEL is fair, from a financial point of view, to the holders of common
stock of Uniphase. The terms and conditions of the Merger are set out more fully
in the Agreement.

     BT Alex. Brown Incorporated ("BT Alex. Brown"), as a customary part of its
investment banking business, is engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, private placements and valuations for estate, corporate and other
purposes. We have acted as financial advisor to the Board of Directors of
Uniphase in connection with the Merger and will receive a fee for our services.
We have acted as co-managing underwriter to Uniphase in Uniphase's public
offering of its securities. BT Alex. Brown regularly publishes research reports
regarding the communications industry and the businesses and securities of
publicly owned companies in the communications industry. In the ordinary course
of business, BT Alex. Brown may actively trade the securities of Uniphase and
JDS FITEL for our own account and the account of our customers and, accordingly,
may at any time hold a long or short position in securities of Uniphase and JDS
FITEL.

     In connection with this opinion, we have reviewed certain publicly
available financial information and other information concerning Uniphase and
JDS FITEL and certain internal analyses and other information furnished to us by
Uniphase and JDS FITEL. We have also held discussions with the members of the
senior management of Uniphase and JDS FITEL regarding the business and prospects
of Uniphase and JDS FITEL and the prospects of a combined company. In addition,
we have (i) compared certain financial information for JDS FITEL and Uniphase
with similar information for companies whose securities are publicly traded,

                                      H-1

(ii) reviewed the financial terms of certain recent business combinations which
we deemed to be comparable, (iii) reviewed a draft of the Agreement and certain
related documents, (iv) performed an analysis of the relative contributions of
Uniphase and JDS FITEL based on certain pro forma combined financial information
of Uniphase and JDS FITEL following consummation of the Merger, (v) reviewed the
premiums paid in certain recent business combinations which we deemed to be
comparable, and (vi) performed such other studies and analyses and considered
such other factors as we deemed appropriate.

     We have not independently verified the information described above and for
purposes of this opinion have assumed the accuracy and completeness of such
information and that such information is a fair presentation of the underlying
facts and circumstances. With respect to the information relating to the
prospects of Uniphase and JDS FITEL, we have assumed that such information
reflects the best currently available judgments and estimates of the management
of Uniphase and JDS FITEL, as the case may be, as to the likely future financial
performance of Uniphase and JDS FITEL. In addition, we have not made nor been
provided with an independent evaluation or appraisal of the assets of Uniphase
or JDS FITEL, nor have we been furnished with any such evaluations or
appraisals. Our opinion is necessarily based upon market, economic and other
conditions as they exist and can be evaluated as of the date of this letter and
on the information noted above available to us as of the date hereof. It should
be understood that, although subsequent developments may affect this opinion, we
assume no obligation to update, revise or reaffirm this opinion. In rendering
this opinion, we have assumed that the Merger will be consummated substantially
on the terms described in the draft of the Agreement provided to us for our
review, without any waiver of any material terms or conditions by any party
thereto. We have also assumed that the Merger will be consummated in a manner
that complies in all respects with the applicable provisions of the Securities
Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and
all applicable United States federal and state statutes, rules and regulations
and Canadian national, provincial or territorial statutes, rules or regulations.

     We have been retained by the Board of Directors of Uniphase as financial
advisor in connection with the Merger and for the purpose of rendering this
opinion. A portion of our fee is due and payable upon delivery of this opinion
and a portion of our fee is due and payable upon the consummation of the Merger.

     Our advisory services and the opinion expressed herein were prepared for
the use of the Board of Directors of Uniphase and this opinion is not intended
to be and does not constitute a recommendation to any stockholder of Uniphase as
to how such stockholder should vote on the Merger. This opinion does not address
the relative merits of the Merger and any other transactions or business
strategies discussed by the Board of Directors of Uniphase as alternatives to
the Merger, or the underlying business decision of the Board of Directors of
Uniphase to proceed with the Merger. This opinion may not be published or
otherwise used or referred to, nor shall any public reference to BT Alex. Brown
be made, without our prior written consent. We hereby consent, however, to the
inclusion of this opinion in its entirety as an exhibit to any proxy or
registration statement distributed to the shareholders of Uniphase or JDS FITEL
in connection with the approval of the Merger and to any description of, or
reference to, this opinion therein in a form and substance acceptable to us and
our legal counsel.

     Based upon and subject to the foregoing, it is our opinion that, as of the
date of this letter, the Exchange Consideration to be paid by Uniphase to the
holders of common stock of JDS FITEL pursuant to the Agreement is fair, from a
financial point of view, to the holders of common stock of Uniphase.

                                           Very truly yours,

                                           BT ALEX. BROWN INCORPORATED

      The Board of Directors
      JDS FITEL Inc.
      570 West Hunt Club
      Nepean, Ontario
      K2G 5W8

      To The Board of Directors:

      CIBC Wood Gundy Securities Inc. ("CIBCWG") understands that JDS FITEL Inc.
      ("JDS" or the "Company") is contemplating entering into a merger agreement
      among the Company, Uniphase Exchangeco (Canada) and Uniphase Corporation
      ("Uniphase"), to be dated the 28(th) day of January, 1999 (the "Merger
      Agreement"), which provides for JDS and Uniphase to combine their business
      operations through a plan of arrangement which would result in JDS
      becoming a wholly-owned subsidiary of Uniphase (the "Transaction"). As set
      forth more fully in the Merger Agreement, as a result of the Transaction,
      each shareholder of the Company who is a Canadian resident will receive
      for each common share of the Company ("Company Common Share") held, at his
      or her option, (i) 0.50855 shares (the "Exchange Ratio") of common stock
      of Uniphase ("Uniphase Common Shares") or (ii) the Exchange Ratio of
      exchangeable shares of Uniphase Exchangeco (Canada), which are
      exchangeable on a share for share basis for Uniphase Common Shares.
      Shareholders of the Company who are not Canadian residents will receive,
      for each Company Common Share held, the Exchange Ratio of Uniphase Common
      Shares. The terms and conditions of the Transaction are more fully set
      forth in the Merger Agreement.

      The Board of Directors of the Company (the "Board") has retained CIBCWG to
      review the Transaction and to provide to the Board financial advice and an
      opinion (the "Fairness Opinion") that the Transaction is fair, from a
      financial point of view, to the common shareholders of the Company.

      CIBCWG'S ENGAGEMENT

      The Board initially contacted CIBCWG regarding potential transaction
      opportunities in August of 1998, and CIBCWG was formally engaged by the
      Company to provide strategic and financial advice under an agreement
      between the Company and CIBCWG (the "Engagement Agreement") dated November
      23, 1998. As part of the Engagement Agreement, CIBCWG agreed to render a
      fairness opinion in connection with a prospective transaction involving
      the Company, if so requested.

                                      I-1

                                                          CIBC WOOD GUNDY
                                                          SECURITIES INC.

      Fees payable to CIBCWG pursuant to the Engagement Agreement will cover
      services related to the Fairness Opinion, and CIBCWG will be reimbursed
      for all reasonable out-of-pocket expenses in connection therewith. In
      addition, JDS has agreed to indemnify CIBCWG in respect of certain
      liabilities that may arise out of its engagement. CIBCWG has consented to
      the inclusion of the Fairness Opinion in its entirety, together with a
      summary thereof, in the joint proxy circular to be sent to the Company's
      and Uniphase's shareholders and to the filing thereof, if necessary, by
      the Company with the securities commissions or similar regulatory
      authorities in each province of Canada and with the United States
      Securities and Exchange Commission.

      CIBCWG'S CREDENTIALS

      CIBCWG is one of Canada's largest investment banking firms, with
      operations in all facets of corporate and government finance, mergers and
      acquisitions, equity and fixed income sales and trading and investment
      research. The Fairness Opinion expressed herein is the opinion of CIBCWG,
      and the form and content have been approved by a committee of its
      directors, each of whom is experienced in merger, acquisition, divestiture
      and valuation matters.

      CIBCWG is not an insider, associate or affiliate of the Company or to any
      other party to the Merger Agreement. CIBCWG has provided investment
      banking services to the Company in the past, including acting as lead
      manager in the underwriting of securities of the Company during the past
      24 months.

            have deemed relevant.

      CIBCWG has not, to the best of its knowledge, been denied access by the
      Company to any information requested by CIBCWG.

      ASSUMPTIONS AND LIMITATIONS

      With the Board's approval and as provided for in the Engagement Agreement,
      CIBCWG has relied upon, and has assumed, the completeness, accuracy and
      fair presentation of all the financial and other information, data,
      advice, opinions and representations obtained by it from public sources,
      the Company, senior management of the Company and Uniphase and agents and
      advisors to the Company and Uniphase (collectively, the "Information").
      Subject to the exercise of professional judgement and except as expressly
      described herein, we have not attempted to verify independently the
      completeness, accuracy or fair presentation of any of the Information.

      The President and Chief Executive Officer of the Company has represented
      to CIBCWG in a certificate delivered as of the date hereof, among other
      things, that (i) the Information provided by the Company, any of its
      subsidiaries or any of its representatives or agents to CIBCWG relating to
      the Company, or any of its subsidiaries or the Transaction was, at the
      date the Information was provided to CIBCWG, and is, except as has been
      disclosed in writing to CIBCWG, complete, true and correct in all material
      respects, and did not, and does not, contain any untrue statement of a
      material fact in respect of the Company, any of its subsidiaries or the
      Transaction, and did not, and does not, omit to state a material fact in
      respect of the Company, any of its subsidiaries or the Transaction
      necessary to make the Information not misleading in light of the
      circumstances under which the Information was made or provided; and (ii)
      since the dates on which the Information was provided to CIBCWG, except as
      disclosed in writing to CIBCWG, or as publicly disclosed by the Company,
      there has been no material change, financial or otherwise, in the
      financial condition, assets, liabilities (contingent or otherwise),
      business, operations or prospects of the Company, any of its subsidiaries
      and no material change has occurred in the Information or any part thereof
      which would have, or which would reasonably be expected to have, a
      material effect on the Fairness Opinion.

      In preparing the Fairness Opinion, CIBCWG has made several assumptions,
      including that all of the conditions required to implement the Transaction
      will be met and that the representations and warranties in the Merger
      Agreement with respect to the Company and its subsidiaries and affiliates,
      Uniphase and its subsidiaries and affiliates, and the Transaction are
      accurate in all material respects.

      The Fairness Opinion is rendered on the basis of securities markets and
      economic, financial and general business conditions prevailing as at the
      date hereof. In its analyses and in preparing the Fairness Opinion, CIBCWG
      made numerous assumptions with respect to industry performance, general
      business and economic conditions and other matters, many of which are
      beyond the control of CIBCWG or any party involved in the Transaction.

      The Fairness Opinion has been provided for the use of the Board and may
      not be used by any other person or relied upon by any other person other
      than the Board without the express prior written consent of CIBCWG. The
      Fairness Opinion is given as of the date hereof and CIBCWG disclaims any
      undertaking or obligation to advise the Board of any change in any fact or
      matter affecting the Fairness Opinion which may come or be brought to
      CIBCWG's attention after the date hereof. Notwithstanding

                                      I-3

                                                          CIBC WOOD GUNDY
                                                          SECURITIES INC.

      and without limiting the foregoing, in the event that there is any
      material change in any fact or matter affecting the Fairness Opinion after
      the date hereof, CIBCWG reserves the right to change, modify or withdraw
      the Fairness Opinion.

      CIBCWG believes that its analyses must be considered as a whole and that
      selecting portions of the analyses or the facts considered by it, without
      considering all factors and analyses together, could create a misleading
      view of the process underlying the Fairness Opinion. The preparation of a
      fairness opinion is a complex process and is not necessarily susceptible
      to partial analysis or summary description. Any attempt to do so could
      lead to undue emphasis on any particular factor or analysis. The Fairness
      Opinion is not and should not be construed as a recommendation to any
      holder of the Company's common shares as to whether to vote in favour of
      the Transaction.

      We understand that the Transaction is not subject to the formal valuation
      requirements under Ontario Securities Commission Policy Statement No. 9.1
      and Quebec Securities Commission Policy Statement No. Q-27. Accordingly,
      we were not engaged to prepare and have not prepared a formal valuation or
      appraisal of the common shares, assets or liabilities (contingent or
      otherwise) of the Company and the Fairness Opinion should not be construed
      as such.

      CONCLUSION

      Based upon and subject to the foregoing, it is our opinion as of the date
      hereof that the Transaction is fair, from a financial point of view, to
      holders of the Company Common Shares.

      Yours very truly,

                                 [SIG]

                                   APPENDIX J
                            SECTION 190 OF THE CBCA

    Please note that the right provided in the Interim Order to JDS Shareholders
to dissent from the JDS Arrangement Resolution differs from the dissent right
set out in section 190 of the CANADA BUSINESS CORPORATIONS ACT in one respect.
In order for a JDS Shareholder to exercise his or her dissent right, the JDS
Shareholder must provide a Dissent Notice to JDS PRIOR TO 5:00 P.M. ON THE
BUSINESS DAY PRECEDING THE JDS MEETING. This differs from the CBCA dissent right
set out below, which requires that a shareholder wishing to exercise the dissent
right in respect of a proposed resolution must provide a notice of dissent AT OR
BEFORE the meeting at which the resolution is to be voted on.

190.(1) RIGHT TO DISSENT -- Subject to sections 191 and 241, a holder of shares
    of any class of a corporation may dissent if the corporation is subject to
    an order under paragraph 192(4)(d) that affects the holder or if the
    corporation resolves to

     (a) amend its articles under section 173 or 174 to add, change or remove
       any provisions restricting or constraining the issue, transfer or
       ownership of shares of that class;

     (b) amend its articles under section 173 to add, change or remove any
       restriction on the business or businesses that the corporation may carry
       on;

     (c) amalgamate otherwise than under section 184;

     (d) be continued under section 188; or

     (e) sell, lease or exchange all or substantially all its property under
       subsection 189(3).

(2)  FURTHER RIGHT -- A holder of shares of any class or series of shares
     entitled to vote under section 176 may dissent if the corporation resolves
     to amend its articles in a manner described in that section.

(3)  PAYMENT FOR SHARES -- In addition to any other right he may have, but
     subject to subsection (26), a shareholder who complies with this section is
     entitled, when the action approved by the resolution from which he dissents
     or an order made under subsection 192(4) becomes effective, to be paid by
     the corporation the fair value of the shares held by him in respect of
     which he dissents, determined as of the close of business on the day before
     the resolution was adopted or the order was made.

       to consent to the withdrawal and the shareholder is reinstated to his
       full rights as a shareholder; or

     (b) retain a status as a claimant against the corporation, to be paid as
       soon as the corporation is lawfully able to do so or, in a liquidation,
       to be ranked subordinate to the rights of creditors of the corporation
       but in priority to its shareholders.

(26) LIMITATION -- A corporation shall not make a payment to a dissenting
     shareholder under this section if there are reasonable grounds for
     believing that

     (a) the corporation is or would after the payment be unable to pay its
       liabilities as they become due; or

       than the aggregate of its liabilities.
