                                UNIPHASE

  Uniphase Corporation designs, develops, manufactures and markets laser 
subsystems and components and modules for fiber optic 
telecommunications and cable television systems and laser subsystems.  
On January 28, 1999, we and JDS FITEL Inc., a Canadian corporation, 
executed a definitive agreement to combine our companies in a 
combination of equals.  The combined company will have a total market 
value of U.S. $6.1 billion based upon the January 27, 1999 closing 
prices of each company's stock.  Under the terms of the agreement, JDS 
shareholders will, subject to certain conditions, be entitled to 
receive 0.50855 shares of exchangeable shares of JDS Uniphase Canada 
Ltd., a subsidiary of Uniphase, or 0.50855 shares of our common stock, 
for each common share of JDS they hold.  The exchangeable shares are 
the economic and voting equivalent of shares of our common stock and 
will be exchangeable for shares of our common stock on a one-for-one 
basis at any time.  Following the effective date of the combination, 
subject to stockholder approval, we expect to change our name to "JDS 
Uniphase Corporation."  Our common stock will continue to be quoted on 
the Nasdaq National Market under the new symbol "JDSU" and we will 
continue to report our financial results in U.S. dollars.

  Our principal telecommunications products consist of source lasers, 
modulators, pump lasers and transmitter modules.  These products are 
used in today's advanced fiber optic telecommunications networks to 
provide the initial light signal, to encode the signal and to amplify 
the signal over the long distances over which these networks are 
deployed.  Our laser subsystems are designed for a number of 
applications and are purchased by our customers for inclusion into 
equipment for biotechnology, industrial process control and 
measurement, graphics and printing, and semiconductor inspection 
equipment and other applications.

  Our initial products consisted of laser subsystems.  These industrial 
lasers are used as a light source within various types of equipment 
manufactured by our customers.  We entered the telecommunications 
markets in 1995 when we acquired United Technologies Photonics, then a 
wholly owned subsidiary of United Technologies Research Center located 
in Hartford, Connecticut.  Since that acquisition, our strategy has 
been to broaden our offering of telecommunications components and 
modules through further acquisitions and internal growth.

  Following our combination with JDS, we will add JDS' products to the 
combined company's product line.  JDS designs and manufactures a broad 
range of passive fiberoptic products.  In addition, JDS distributes 
complementary fiberoptic interconnect products that are manufactured by 
third parties.







  We currently operate the following subsidiaries or divisions offering 
products for the telecommunications industry:

                                RISK FACTORS

Holders of Exchangeable Shares Are Subject to Risks Not Shared by 
Holders of Our Common Stock

Canadian Resident Holders of Exchangeable Shares May Not Be Able 
to Control the Timing of Gain Recognition 

We structured our transaction with JDS to provide for a tax 
deferral for Canadian tax purposes for Canadian residents who 
receive exchangeable shares from the combination.  However, 
Canadian residents will generally only be able to obtain this 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 shares of our 
common stock.  See "Income Tax Considerations."  Apart from the 
Canadian residents' ability to dispose of or convert their 
exchangeable shares, under certain circumstances, we or our 
subsidiaries may compel a purchase of the exchangeable shares.  
See "Plan of Distribution - Procedures for Issuance of Our 
Common Stock."  Accordingly, a holder of exchangeable shares 
cannot control whether such holder will receive shares of our 
common stock by way of redemption of the exchangeable shares or 
by way of purchase of the exchangeable shares by us or our 
subsidiaries.  The Canadian federal income tax consequences of a 
redemption differ from those of a purchase.  

The Exchangeable Shares and Our Common Stock May Trade at 
Different Values

Although we believe that the market price of the exchangeable 
shares on The Toronto Stock Exchange and the market price of our 
common stock on Nasdaq will reflect essentially equivalent 
values, the market price of our common stock may not be 
identical, or even similar, to the market price of the 
exchangeable shares.  The Toronto Stock Exchange has 
conditionally approved the listing of the exchangeable shares on 
the effective date of our combination with JDS, subject to 
fulfilling all of the requirements of The Toronto Stock Exchange.  
Our common stock is listed on Nasdaq.  We have agreed that the 
shares of our common stock issued pursuant to the combination 
with JDS 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 our common 
stock 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 
Toronto Stock Exchange and the price at which shares of our 
common stock will trade will be based upon the market for such 
shares on Nasdaq. 

Our Stock Price Could Fluctuate Substantially

The Unpredictability of Our Quarterly Operating Results Could 
Cause Our Stock Price to be Volatile or Decline.

We have experienced and expect to continue to experience 
significant fluctuations in our quarterly results, which has 
caused and may in the future cause substantial fluctuations in 
the market price of our common stock.  All of the concerns we 
discuss under Risk Factors could affect our operating results, 
including, among others

     o the timing of the receipt of product orders from a 
       limited number of major customers,
     o the loss of one or more of our major suppliers,
     o competitive pricing pressures,
     o the costs associated with the acquisition or disposition 
       of businesses,
     o our ability to design, manufacture and ship 
       technologically advanced products with satisfactory 
       yields on a timely and cost-effective basis, 
     o the announcement and introduction of new products by us, 
       and
     o expenses associated with any intellectual property 
       litigation.

In addition to concerns potentially affecting our operating 
results addressed elsewhere under Risk Factors, the following 
factors may also influence our operating results:

     o our product mix,
     o the relative proportion of our domestic and 
       international sales, and
     o the timing differences between when we incur expenses to 
       increase our marketing and sales capabilities and when 
       we realize benefits, if any, from such expenditures.  

Furthermore, our sales often reflect orders shipped in the same 
quarter that they are received, which makes our sales vulnerable 
to short term fluctuations in customer demand and difficult to 
predict.  Also, customers may cancel or reschedule shipments, and 
production difficulties could delay shipments.  In addition, we 
sell our telecommunications equipment products to Original 
Equipment Manufacturers who typically order in large quantities 
and therefore the timing of such sales may significantly affect 
our quarterly results.  An OEM supplies system level network 
products to telecommunications carriers and others and 
incorporates our components in these system level products.  The 
timing of such OEM sales can be affected by factors beyond our 
control, such as demand for the OEMs' products and manufacturing 
risks experienced by OEMs.  In this regard, we have experienced 
rescheduling of orders by customers in each of our markets and 
may experience similar rescheduling in the future.  As a result 
of all of these factors, our results from operations may vary 
significantly from quarter to quarter.

In addition to the effect of ongoing operations on quarterly 
results, acquisitions or dispositions of businesses, products or 
technologies by us have resulted in and may in the future result 
in reorganization of our operations, substantial charges or other 
expenses, which have caused and may in the future cause 
fluctuations in our quarterly operating results and cash flows.  
For example, in the second and fourth quarters of fiscal 1998, we 
incurred charges of $6.6 million and $33.7 million, respectively 
for acquired in-process research and development in connection 
with the acquisition of Uniphase Fiber Components and Uniphase 
Netherlands.  In the third quarter of fiscal 1997, we incurred 
charges of $33.3 million for acquired in-process research and 
development in connection with the acquisition of Uniphase Laser 
Enterprise.  In addition, we incurred other charges in connection 
with acquisitions completed in fiscal 1999, 1998 and 1997. 

Finally, our net revenues and operating results in future 
quarters may be below the expectations of public market 
securities analysts and investors.  In such event, the price of 
our common stock would likely decline, perhaps substantially.

Factors Other Than Our Quarterly Results Could Cause Our Stock 
Price to be Volatile or Decline 

The market price of our common stock has been and is likely to 
continue to be highly volatile due to causes other than our 
historical quarterly results, such as

     o announcements of technological innovations or new 
       products by our competitors,
     o developments with respect to patents or proprietary 
       rights, 
     o governmental regulatory action, and
     o general market conditions.

In addition, the stock market has from time to time experienced 
significant price and volume fluctuations that are unrelated to 
the operating performance of particular companies.

We are Subject to Manufacturing Difficulties

If We Do Not Achieve Acceptable Manufacturing Yields or 
Sufficient Product Reliability Our Operating Results Could Suffer

The manufacture of our products involves highly complex and 
precise processes, requiring production in highly controlled and 
clean environments.  Changes in our manufacturing processes or 
those of our suppliers or their inadvertent use of defective or 
contaminated materials could significantly reduce our 
manufacturing yields and product reliability.  Because the 
majority of our manufacturing costs are relatively fixed, 
manufacturing yields are critical to our results of operations.  
Certain divisions of Uniphase, including Uniphase Laser 
Enterprise and Uniphase Netherlands, have in the past experienced 
lower than expected production yields, which could delay product 
shipments and impair gross margins.  These divisions or any of 
our other manufacturing facilities may not maintain acceptable 
yields in the future.  

During the fourth quarter of fiscal 1998, we commenced 
construction of a new laser fabrication facility in the 
Netherlands for Uniphase Netherlands, which we acquired in June 
1998.  Our Uniphase Netherlands facility has not achieved 
acceptable manufacturing yields since the June 1998 acquisition, 
and there is continuing risk attendant to this new facility and 
its manufacturing yields and costs.  Uniphase Netherlands may not 
successfully manufacture laser products in the future at yield or 
cost levels necessary to meet our customers' needs, if at all.  
In addition, Uniphase Fiber Components is establishing a 
production facility in Sydney, Australia for fiber Bragg grating 
products.  This facility may not manufacture grating products to 
customers specifications at the cost and yield levels required.  
To the extent we do not achieve acceptable manufacturing yields 
or experience product shipment delays, our business, operating 
results and financial condition would be materially and adversely 
affected.

If Our Customers Do Not Qualify Our Manufacturing Lines For 
Volume Shipments Our Operating Results Could Suffer.

Customers will not purchase any products (other than limited 
numbers of evaluation units) prior to qualification of the 
manufacturing line for the product.  Each new manufacturing line 
must go through varying levels of qualification with our 
customers. This qualification process determines whether the 
manufacturing line achieves the customers' minimum quality, 
performance and reliability standards.  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.  As noted in the previous paragraph, we are 
currently completing new manufacturing facilities in the 
Netherlands and Australia.  We may experience delays in obtaining 
customer qualification of these facilities.  If we fail in the 
timely qualification of these or other new manufacturing lines, 
our operating results and customer relationships would be 
adversely affected.  

Difficulties We May Encounter Managing Our Growth Could Adversely 
Affect Our Results of Operations

  We have historically achieved our growth through a combination of 
acquisitions and internally developed new products. As part of our 
strategy to sustain growth, we expect to continue to pursue 
acquisitions of other companies, technologies and complementary product 
lines. We also expect to continue developing new solid state lasers, 
components and other products for OEM customers and attempt to further 
penetrate the telecommunications and CATV markets through these new 
products.  Both strategies include risks.  The success of each 
acquisition will depend upon

     o our ability to manufacture and sell the products of the 
       businesses acquired, 
     o continued demand for these products by our customers, 
     o our ability to integrate the acquired business' operations, 
       products and personnel, 
     o our ability to retain key personnel of the acquired 
       businesses, and 
     o our ability to expand our financial and management controls 
       and reporting systems and procedures.

  In March 1997, we acquired Uniphase Laser Enterprise, which produces 
our 980-nm pump laser products. In June 1998, we acquired Uniphase 
Netherlands. In the case of both acquisitions, we acquired businesses 
that had previously been engaged primarily in research and development 
and that needed to make the transition from a research activity to a 
commercial business with sales and profit levels that are consistent 
with our overall financial goals.  This transition has not yet been 
completed at Uniphase Netherlands, which continues to operate at higher 
expense levels and lower gross margins than those required to meet our 
profitability goals. In addition, in August 1998, we acquired certain 
assets of Chassis, and in November 1998 acquired Uniphase Broadband.  
See "Recent Developments."  We may not successfully manufacture and 
sell our products or successfully manage our growth, and failure to do 
so could have a material adverse effect on our business, financial 
condition and operating results.

  Since 1997, when we acquired Uniphase Laser Enterprise, we have 
increased our marketing, customer support and administrative functions 
to support an increased level of operations primarily from our 
telecommunications products.  We may not be successful in creating this 
infrastructure nor may we realize any increase in the level of our 
sales and operations through our new products.  We commenced operations 
at Uniphase Telecommunications Products in 1996 to penetrate the CATV 
markets, and at Uniphase Network Components in 1998 to develop and 
market a line of complementary optical components for our 
telecommunications customers. In each case, we hired development, 
manufacturing and other staff in anticipation of developing and selling 
new products.  Our operations may not achieve levels sufficient to 
justify the increased expense levels associated with these new 
businesses.

Difficulties in Integrating Uniphase and JDS Could Adversely 
Affect Our Business

Consistent with our historical growth strategy, in January 1999, 
we agreed to combine with JDS. If we fail to successfully 
integrate our and JDS' businesses, our business could suffer.  We 
and JDS have complementary business operations located 
principally in the United States, Canada and Europe.  Our success 
depends in large part on the successful integration of these 
operations and the technologies and personnel of the two 
companies following the combination.  Our future management will 
come from the current management teams of both companies and many 
members of management will not have previously worked and 
communicated with other members of management.  The integration 
of the two businesses may result in unanticipated operations 
problems, expenses and liabilities and diversion of management 
attention.  The integration may not be successful and our 
operating results may suffer as a result.

If We Fail to Efficiently Combine Our and JDS' Sales and 
Marketing Forces, Our Sales Could Suffer

We may experience disruption in sales and marketing in connection 
with our efforts to integrate our and JDS' sales channels, and we 
may be unable to efficiently or effectively correct such 
disruption or achieve our sales and marketing objectives after 
integration.  In addition, sales cycles and sales models for our 
and JDS' various products may vary significantly from product to 
product.  Our and JDS' 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 our combination with JDS.  As 
a result, we may fail 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 our business, financial condition or operating results.

Integration Costs and Expenses Associated with Our Combination 
with JDS May be Substantial

We estimate we and JDS together will incur direct costs 
associated with the combination of approximately $12 million 
which will be included as a part of the total purchase cost for 
accounting purposes.  We believe we may incur charges to 
operations, which are not currently reasonably estimable, in the 
quarter in which the combination occurs or the following 
quarters, to reflect costs associated with integrating the two 
companies.  We may incur additional material charges in 
subsequent quarters to reflect additional costs associated with 
the combination.

Our Operating Results May Suffer as a Result of Purchase Accounting 
Treatment, the Impact of Amortization of Goodwill and Other Intangibles 
Relating to Our Combination with JDS

  Under U.S. generally accepted accounting principles that will apply to 
us after the completion of our combination with JDS, we will account 
for the combination using the purchase method of accounting.  Under 
purchase accounting, we will record the estimated market value of our 
common shares and the exchangeable shares issued in connection with our 
combination with JDS, the fair value of the options to purchase JDS 
common shares which become options to purchase our common shares on the 
effective date of our combination with JDS, and the amount of the 
direct transaction costs 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 in-process research and development, acquired technology, 
acquired trademarks and trade names and acquired workforce, based on 
their respective fair values.  We will allocate the excess of the 
purchase cost over the fair value of the net assets to goodwill. We 
will immediately expense in-process research and development, which is 
currently estimated at $177 million.  We will amortize intangible 
assets including goodwill over a five year period. The amount of 
purchase cost to be allocated to goodwill and other intangibles is 
estimated to be approximately $3.2 billion, including the related 
deferred tax effect.  If we amortized goodwill and other intangible 
assets in equal quarterly amounts over a five year period following 
completion of our combination with JDS, the accounting charge 
attributable to these items would be $161 million per quarter and $643 
million per fiscal year.  As a result, purchase accounting treatment of 
our combination with JDS will result in a net loss for us in the 
foreseeable future which could have a material and adverse effect on 
the market value of our common stock following completion of the 
combination.  

Our Sales Would Suffer if One or More of Our Key Customers 
Substantially Reduced Orders of Our Products

  Our customer base is highly concentrated.  Historically, orders from a 
relatively limited number of OEM customers accounted for a substantial 
portion of our net sales from telecommunications products.  We expect 
that, for the foreseeable future, sales to a limited number of 
customers will continue to account for a high percentage of our net 
sales.  Sales to any single customer may vary significantly from 
quarter to quarter.  If current customers do not continue to place 
orders we may not be able to replace these orders with new orders from 
new customers.  In the telecommunications markets, our customers 
evaluate our products and competitive products for deployment in large 
telecommunications systems that they are installing.  Our failure to be 
selected by a customer for particular system projects can significantly 
impact our business, operating results and financial condition.  
Similarly, even if our customers select us, if our customers are not 
selected as the primary supplier for an overall system installation, we 
can be similarly adversely affected.  Such fluctuations could have a 
material adverse effect on our business, operating results and 
financial condition.  

  One telecommunications customer, CIENA Corporation, accounted for 
approximately 12% of our net sales for fiscal 1998.  One laser 
subsystems customer, the Applied Biosystems Division of Perkin-Elmer 
Corporation, accounted for approximately 10% and 12% of our net sales 
for fiscal 1997 and 1996, respectively.  One additional customer, KLA-
Tencor Corporation, purchased both Laser subsystems and Ultrapointe 
systems and accounted for 12% and 13% of our consolidated net sales in 
fiscal 1998 and 1996, respectively.  The Ultrapointe product line was 
sold to KLA-Tencor Corporation in December 1998 and will not be a 
source of future sales.  No other customers represented 10% or more of 
total sales during fiscal 1998.  The loss or delay of orders from these 
or other OEM customers could have a materially adverse effect on our 
business, financial condition and operating results.

  If the combination with JDS occurred on July 1, 1997, one 
telecommunications customer would have accounted for approximately 12% 
of the combined company's net sales for the year ended June 30, 1998.  
The loss or delay of orders from this customer could have an material 
adverse effect on the combined company's business, financial condition 
and operating results.  If the combination with JDS occurred on July 1, 
1997, none of our other customers would have represented 10% or more of 
our combined total sales.  

Interruptions Affecting Our Key Suppliers Could Disrupt Production and 
Compromise Our Product Quality and Adversely Affect Our Sales

  We have sole or limited numbers of suppliers for certain of our 
products.  We currently obtain various components included in the 
manufacture of our products from single or limited source suppliers.  A 
disruption or loss of supplies from these companies or a price increase 
for these components would have a material adverse effect on our 
results of operations, product quality and customer relationships.  We 
currently utilize a sole source for the crystal semiconductor chip sets 
incorporated in our solid state microlaser products and acquire our 
pump diodes for use in our solid state laser products from Opto Power 
Corporation and GEC.  We also obtain lithium niobate wafers, gallium 
arsenide wafers, specialized fiber components and certain lasers used 
in our telecommunications products primarily from Crystal Technology, 
Inc., Fujikura, Ltd., Philips Key Modules, and Sumitomo, respectively.  
We do not have long-term or volume purchase agreements with any of 
these suppliers, and these components may not in the future be 
available in the quantities required by us, if at all.

We May Become Subject to Collective Bargaining Agreements

  Our employees who are employed at manufacturing facilities located in 
North America are not bound by or party to any collective bargaining 
agreements with us.  These employees may become bound by or party to 
one or more collective bargaining agreements with us or JDS in the 
future.  Certain of our and JDS' employees 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 our 
related costs and our flexibility with respect to managing our business 
operations involving such employees may be materially adversely 
affected.  

Any Failure to Remain Competitive in Our Industry Would Impair Our 
Operating Results 

If Our Business Operations are Insufficient to Remain Competitive 
in Our Industry Our Operating Results Could Suffer 

The telecommunications and laser subsystems markets in which we 
sell our products are highly competitive.  In each of the markets 
we serve, we face intense competition from established 
competitors.  Many of these competitors have substantially 
greater financial, engineering, manufacturing, marketing, service 
and support resources than do we and may have substantially 
greater name recognition, manufacturing expertise and capability 
and longer standing customer relationships than do we.  To remain 
competitive, we believe we must maintain a substantial investment 
in research and development, marketing, and customer service and 
support.  We may not compete successfully in the laser or 
telecommunications industries in the future, and we may not have 
sufficient resources to continue to make such investments, or we 
may not make the technological advances necessary to maintain our 
competitive position so that our products will receive market 
acceptance.  In addition, technological changes or development 
efforts by our competitors may render our products or 
technologies obsolete or uncompetitive.

If We Fail to Successfully Develop and Market Solid State Lasers 
to Replace the Declining Markets for Our Gas Lasers, Our 
Operating Results Could Suffer

The market for gas lasers is mature and expected to decline as 
customers replace conventional lasers, including gas lasers, with 
solid state lasers. Gas laser subsystems sales accounted for 
26.3%, 37.3% and 52.9% of our net sales for the fiscal years 
ended 1998, 1997 and 1996, respectively.  Solid state lasers are 
currently expected to be the primary commercial laser technology 
in the future.  Consequently, we have devoted substantial 
resources to developing and commercializing our solid state laser 
products.  We believe that some companies are further advanced 
than us in solid state laser development and are competing with 
us for many of the same opportunities.  To be competitive in our 
laser markets, we believe continued manufacturing cost reductions 
and enhanced performance of our laser products will be required 
on a continuing basis as these markets further mature.  However, 
our solid state laser products may not be competitive with 
products of other companies as to cost or performance in the 
future.

Fiberoptic Component Average Selling Prices Are Declining

Prices for telecommunications industry fiberoptic components are 
generally declining due to, among other things, increased 
competition and greater unit volumes as telecommunication service 
providers continue to deploy fiberoptic networks.  We and JDS 
have in the past and may in the future experience substantial 
period to period fluctuations in average selling prices.  We 
anticipate that average selling prices will decrease in the 
future in response to product introductions by competitors and us 
or to other factors, including price pressures from significant 
customers.  Therefore, we must continue to (1) timely develop and 
introduce new products that incorporate features that can be sold 
at higher selling prices and (2) reduce our manufacturing costs.  
Failure to achieve any or all of the foregoing could cause our 
net sales and gross margins to decline, which may have a material 
adverse effect on our business, financial condition, and 
operating results.  

If We Fail  to Attract and Retain Key Personnel Our Business 
Could Suffer

Our future depends, in part, on our ability to attract and retain 
certain key personnel.  In particular, our research and 
development efforts depend on hiring and retaining qualified 
engineers.  Competition for highly skilled engineers is extremely 
intense, and we are currently experiencing difficulty in 
identifying and hiring certain qualified engineers in many areas 
of our business.  We may not be able to hire and retain such 
personnel at compensation levels consistent with our existing 
compensation and salary structure.  Our future also depends on 
the continued contributions of our executive officers and other 
key management and technical personnel, none of whom currently 
has an employment agreement with us and each of whom would be 
difficult to replace.  We do not maintain a key person life 
insurance policy on the Chief Executive Officer.  The loss of the 
services of one or more of our 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 our business, financial 
condition and operating results.

Our Participation in International Markets Creates Risks to Our 
Business Not Faced by Companies That Sell Their Products in the United 
States

International sales are subject to inherent risks, including  

     o unexpected changes in regulatory requirements,
     o tariffs and other trade barriers,
     o political and economic instability in foreign markets,
     o difficulties in staffing and management,
     o integration of foreign operations,
     o longer payment cycles,
     o greater difficulty in accounts receivable collection,
     o currency fluctuations, and
     o potentially adverse tax consequences.

  International sales accounted for approximately 38.7%, 30.6% and 25.1% 
of net sales in fiscal years 1998, 1997 and 1996, respectively.  
International sales (excluding sales to the U.S.) accounted for 
approximately 24.5%, 20.2% and 31.8% of JDS' net sales in fiscal years 
1998, 1997 and 1996, respectively.  We expect that international sales 
will continue to account for a significant portion of our net sales.  
We may continue to expand our operations outside of the United States 
and to enter additional international markets, both of which will 
require significant management attention and financial resources.  

  Since a significant portion of our foreign sales are denominated in 
U.S. dollars, our products may also become less price competitive in 
countries in which local currencies decline in value relative to the 
U.S. dollar.  Our business and operating results may also be materially 
and adversely affected by lower sales levels that typically occur 
during the summer months in Europe and certain other overseas markets.  
Furthermore, the sales of many of our OEM customers depends on 
international sales and, consequently, this further exposes us to the 
risks associated with such international sales.

The Year 2000 Problem May Disrupt Our and Our Customers' and Suppliers' 
Businesses

  We are aware of the risks associated with the operation of information 
technology and non-information technology systems as the millennium 
(year 2000) approaches.  The problem is pervasive and complex, and may 
affect many information technology and non-information technology 
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 our own systems we rely on external systems of 
our customers, suppliers, creditors, financial organizations, utilities 
providers and government entities, both domestic and international 
(which we collectively refer to as "Third Parties").  Consequently, we 
could be affected by disruptions in the operations of Third Parties 
with which we interact.  Furthermore, as customers expend resources to 
correct their own systems, they may reduce their purchasing frequency 
and volume of our products.

  We are using both internal and external resources to assess

     o Our state of readiness (including the readiness of Third 
       Parties, with which we interact) concerning the Year 2000 
       problem, 
     o our costs to correct material Year 2000 problems related to 
       our internal information technology and non-information 
       technology systems,
     o the known risks related to any failure to correct any Year 
       2000 problems we identify, and
     o the contingency plan, if any, that we should adopt should any 
       identified Year 2000 problems not be corrected.

  To date, we have incurred costs not exceeding U.S.$1 million, to 
upgrade our IT and non-IT systems, to among other things, make such 
systems Year 2000 compliant.  We 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, we 
believe, based on (i) available information, (ii) amounts spent to date 
and (iii) the fact that our IT and non-IT systems depend on third-party 
software which, we believe, has been or is being updated to address the 
Year 2000 problem, that we will manage our total Year 2000 transition 
without any material adverse effect on our business operations, 
financial condition, products or financial prospects. The actual 
outcomes and results could be affected by future factors including, but 
not limited to,

     o the continued availability of skilled personnel,
     o cost control,
     o the ability to locate and remediate software code problems,
     o critical suppliers and subcontractors meeting their Year 2000 
       compliance commitments, and
     o timely actions by customers.

  We are working with our software system suppliers and believe that 
certain of these systems are currently not Year 2000 compliant.  We 
have targeted September 30, 1999 as the date by which these systems 
shall be Year 2000 compliant.  In any event, however, we anticipate 
that such systems will be corrected for the Year 2000 problem prior to 
December 31, 1999. We are working with those Third Parties to identify 
any Year 2000 problems affecting such Third Parties that could have a 
material adverse affect on our business, financial condition or results 
of operations. However, it would be impracticable for us 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 information technology 
and non-information technology systems of Third Parties having 
widespread national and international interactions with persons and 
entities generally (for example, certain information technology and 
non-information technology systems of governmental agencies, utilities 
and information and financial networks) that, if uncorrected, could 
have a material adverse impact on our business, financial condition or 
results of operations. We are still assessing the effect the Year 2000 
problem will have on our suppliers and, at this time, cannot determine 
such impact.  However, we have identified alternative suppliers and, in 
the event that any significant supplier suffers unresolved material 
Year 2000 problems, we believe that we would only experience short term 
disruptions in supply, not exceeding 90 days, while such supplier is 
replaced.  

If We Have Insufficient Proprietary Rights or We Failed to Protect 
Those We Have Our Business Would be Materially Impaired

We May Not Obtain the Intellectual Property Rights We Require

The laser, semiconductor capital equipment, and 
telecommunications markets in which we sell our products 
experience frequent litigation regarding patent and other 
intellectual property rights.  Numerous patents in these 
industries are held by others, including academic institutions 
and our competitors.  In the past we have acquired and in the 
future we may seek to acquire license rights to these or other 
patents or other intellectual property to the extent necessary 
for our business.  Unless we are able to obtain such licenses on 
commercially reasonable terms, patents or other intellectual 
property held by others could inhibit our development of new 
products for our markets.  While in the past licenses generally 
have been available to us where third-party technology was 
necessary or useful for the development or production of our 
products, in the future licenses to third-party technology may 
not be available on commercially reasonable terms, if at all.  
Generally, a license, if granted, includes payments by us of up-
front fees, ongoing royalties or a combination thereof.  Such 
royalty or other terms could have a significant adverse impact on 
our operating results.  We are a licensee of a number of third 
party technologies and intellectual property rights and are 
required to pay royalties to these third party licensors on 
certain of our telecommunications products and solid state 
lasers. During fiscal 1998, 1997 and 1996, we expensed $2.0 
million, $1.4 million and $1.3 million, respectively, in license 
and royalty fees primarily in connection with our gas laser 
subsystems.

Our Products May Infringe the Property Rights of Others

The industry in which we operate experiences periodic claims of 
patent infringement or other intellectual property rights.  In 
this regard, third parties may in the future assert claims 
against us concerning our existing products or with respect to 
future products under development by us.  Any litigation to 
determine the validity of any third-party claims could result in 
significant expense to us and divert the efforts of our technical 
and management personnel, whether or not we are successful in 
such litigation.  If we are unsuccessful in any such litigation, 
we could be required to expend significant resources to develop 
non-infringing technology or to obtain licenses to the technology 
that is the subject of the litigation.  We  may not be successful 
in such development or such licenses may not be  available to us.  
Without such a license, we could be enjoined from future sales of 
the infringing product or products.

Our Intellectual Property Rights May Not Be Adequately Protected

Our future depends in part upon our intellectual property, 
including trade secrets, know-how and continuing technological 
innovation.  We currently hold 95 U.S. patents on products or 
processes and certain corresponding foreign patents and have 
applications for certain patents currently pending.  The steps 
taken by us to protect our intellectual property may not 
adequately prevent misappropriation or ensure that others will 
not develop competitive technologies or products.  Other 
companies may be investigating or developing other technologies 
that are similar to ours.  It is possible that patents may not be 
issued from any application pending or filed by us and, if 
patents do issue, the claims allowed may not be sufficiently 
broad to deter or prohibit others from marketing similar 
products.  Any patents issued to us may be challenged, 
invalidated or circumvented.  Further, the rights under our 
patents may not provide a competitive advantage to us.  In 
addition, the laws of certain territories in which our products 
are or may be developed, manufactured or sold, including Asia, 
Europe or Latin America, may not protect our products and 
intellectual property rights to the same extent as the laws of 
the United States.

If We Fail to Successfully Manage Our Exposure to the Worldwide 
Financial Markets, Our Operating Results Could Suffer

  We experience financial market risks, including changes in interest 
rates, foreign currency exchange rates and marketable equity security 
prices.  We utilize derivative financial instruments to mitigate these 
risks.  We do not use derivative financial instruments for speculative 
or trading purposes.  The primary objective of our investment 
activities is to preserve principal while at the same time maximizing 
yields without significantly increasing risk.  To achieve this 
objective, a majority of our marketable investments are floating rate 
and municipal bonds, auction instruments and money market instruments 
denominated in U.S. dollars.  We hedge currency risks of investments 
denominated in foreign currencies with forward currency contracts.  
Gains and losses on these foreign currency investments are generally 
offset by corresponding gains and losses on the related hedging 
instruments, resulting in negligible net exposure to us.  A substantial 
portion of our revenue, expense and capital purchasing activities are 
transacted in U.S. dollars.  However, we do enter into these 
transactions in other currencies, primarily European currencies.  To 
protect against reductions in value and the volatility of future cash 
flows caused by changes in foreign exchange rates, we have established 
hedging programs.  Currency forward contracts are utilized in these 
hedging programs.  Our hedging programs reduce, but do not always 
entirely eliminate the impact of foreign currency exchange rate 
movements.  Actual results on our financial position may differ 
materially.

If We Fail to Obtain Additional Capital at the Times, in the Amounts 
and Upon the Terms Required, Our Business Could Suffer

  We are devoting substantial resources for new facilities and equipment 
for the production of source lasers, fiber-Bragg gratings and modules 
used in telecommunications and for the development of new solid state 
lasers.  Although we believe existing cash balances, cash flow from 
operations and available lines of credit, will be sufficient to meet 
our capital requirements at least through the end of fiscal 1999, we 
may be required to seek additional equity or debt financing to compete 
effectively in these markets.  We cannot precisely determine the timing 
and amount of such capital requirements and will depend on several 
factors, including our acquisitions and the demand for our products and 
products under development.  Such additional financing may not be 
available when needed, or, if available, may not be on terms 
satisfactory to us.

Our Currently Outstanding Preferred Stock and Our Ability to Issue 
Additional Preferred Stock Could Impair the Rights of Our Common 
Stockholders

  Our Board of Directors has the authority to issue up to 800,000 shares 
of undesignated preferred stock and to determine the powers, 
preferences and rights and the qualifications, limitations or 
restrictions granted to or imposed upon any wholly unissued shares of 
undesignated preferred stock and to fix the number of shares 
constituting any series and the designation of such series, without the 
consent of our stockholders.  The preferred stock could be issued with 
voting, liquidation, dividend and other rights superior to those of the 
holders of common stock.  The issuance of preferred stock under certain 
circumstances could have the effect of delaying, deferring or 
preventing a change in control of us.  On June 11, 1998, the Board of 
Directors authorized and declared a dividend distribution of one right 
for each outstanding share of its common stock, to stockholders of 
record at the close of business on July 6,1998, and authorized the 
issuance of one right with each share of common stock issued (including 
shares distributed from treasury) by us thereafter between the record 
date and the distribution date.  Each right entitles the registered 
holder, subject to the terms of the Rights Agreement, to purchase from 
us one unit, equal to one one-thousandth of a share of Series B 
Preferred Stock, at a purchase price of $270 per unit, subject to 
adjustment, for each share of common stock held by the holder.  The 
purchase price is payable in cash or by certified or bank check or 
money order payable to our order.  The description and terms of the 
rights are set forth in a Rights Agreement between us and American 
Stock Transfer & Trust Company, as Rights Agent, dated as of June 22, 
1998, as amended from time to time.

  Certain provisions contained in the rights plan, may have the effect of 
discouraging a third party from making an acquisition proposal for us 
and may thereby inhibit a change in control of us.  For example, such 
provisions may deter tender offers for shares of common stock which 
offers may be attractive to the stockholders, or deter purchases of 
large blocks of common stock, thereby limiting the opportunity for 
stockholders to receive a premium for their shares of common stock over 
the then-prevailing market prices.

Certain Anti-Takeover Provisions Contained in Our Charter and Under 
Delaware Law Could Impair a Takeover Attempt

  We are subject to the provisions of Section 203 of the Delaware General 
Corporation Law prohibiting, under certain circumstances, publicly-held 
Delaware corporations from engaging in business combinations with 
certain stockholders for a specified period of time without the 
approval of the holders of substantially all of its outstanding voting 
stock.  Such provisions could delay or impede the removal of incumbent 
directors and could make more difficult a merger, tender offer or proxy 
contest involving us, even if such events could be beneficial, in the 
short term, to the interests of the stockholders.  In addition, such 
provisions could limit the price that certain investors might be 
willing to pay in the future for shares of our common stock.  Our 
Certificate of Incorporation and Bylaws contain provisions relating to 
the limitations of liability and indemnification of its directors and 
officers, dividing our Board of Directors into three classes of 
directors serving three-year terms and providing that its stockholders 
can take action only at a duly called annual or special meeting of 
stockholders.  These provisions also may have the effect of deterring 
hostile takeovers or delaying changes in control or management of us.

This Prospectus Contains Certain Forward Looking Statements

  Investors should carefully consider the risk factors discussed above in 
evaluating an investment in the common stock offered by this 
prospectus.  The statements contained in this prospectus that are not 
purely historical are "forward-looking statements" within the meaning 
of the Private Securities Litigation Reform Act of 1995 and Section 21E 
of the Securities Exchange Act, including, without limitation, 
statements regarding Uniphase's expectations, hopes, beliefs, 
anticipations, commitments, intentions and strategies regarding the 
future. Actual results could differ from those projected in any 
forward-looking statements for the reasons, among others, detailed in 
the preceding "Risk Factors."  The fact that some of the risk factors 
described in this prospectus may be the same or similar to those 
described in our past filings means only that those risks are present 
in multiple periods.  We believe that many of the risks detailed here 
are part of doing business in the industry in which we compete and will 
likely be present in all periods reported.  The fact that certain risks 
are endemic to the industry does not lessen the significance of the 
risk.  We have made forward-looking statements as of the date of this 
prospectus and assume no obligation to update them, or to update the 
reasons why actual results could differ from those projected in them.

                             USE OF PROCEEDS

  Because the shares of our common stock offered hereunder will be issued 
upon exchange of the exchangeable shares, none of which will be held by 
us, we will receive no proceeds upon such issuance.

                   DESCRIPTION OF UNIPHASE CAPITAL STOCK

  The following summarizes certain provisions of our capital stock, but 
does not purport to be complete and is subject to, and qualified in its 
entirety by, our Certificate of Incorporation and Bylaws and the 
provisions of applicable law.

  Our authorized capital stock consists of 100,000,000 shares of common 
stock, $0.001 par value per share, and 1,000,000 shares of preferred 
stock, $0.001 par value per share, 100,000 shares of which are 
designated Series A Preferred Stock and 100,000 shares of which are 
designated Series B Preferred Stock.  As of May 14, 1999, there were 
40,464,807 shares of our common stock issued and outstanding, 100,000 
shares of Series A Preferred Stock issued and outstanding, and no 
shares of Series B Preferred Stock issued and outstanding.  In 
connection with the proposed combination with JDS, our stockholders 
will be asked to approve an increase in our authorized common stock 
from 100,000,000 to 200,000,000 shares.  

Common Stock

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

Preferred Stock

  The Board of Directors has the authority, without further action by our 
stockholders, to issue up to 800,000 shares of preferred stock 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 shares of preferred stock 
could adversely affect the voting power of our common stockholders and 
the likelihood that our common stockholders 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 Stock

  We currently have 100,000 shares of Series A Preferred Stock 
authorized, issued and outstanding, all of which were issued to Philips 
in connection with the acquisition of Uniphase Netherlands B.V 
("UNL").  The shares of Series A Preferred Stock are convertible into 
shares of our common stock 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 us and Philips. The shares of 
our common stock into which the shares of Series A Preferred Stock are 
convertible are calculated based upon (i) unit shipments of certain 
products by UNL through June 30, 2002, and (ii) our common stock 
trading price at the time such calculation is determined.
The shares of Series A Preferred Stock rank junior to any other class 
of preferred stock that hereafter may be issued by us 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 shares of 
Series A Preferred Stock have no voting rights except as required by 
law and except that approval of Philips (as long as Philips is a holder 
of shares of Series A Preferred Stock), or more than 50% of the 
outstanding shares of Series A Preferred Stock (in the event that 
Philips is no longer a holder of shares of Series A Preferred Stock), 
is required to alter our Certificate of Incorporation so as to (i) 
adversely affect the rights and privileges of the holders of shares of 
Series A Preferred Stock, or (ii)  increase the number of authorized 
shares of Series A Preferred Stock.  The holders of shares of Series A 
Preferred Stock have no right to dividends or other distributions.  The 
holders of a majority of the shares of Series A Preferred Stock have 
the right to cause us to redeem the outstanding shares of Series A 
Preferred Stock or convert such shares into shares of our common stock 
if certain events occur on or before June 30, 2002. In addition, each 
share of Series A Preferred Stock that has not been redeemed or 
converted prior to July 1, 2002, will automatically be converted into 
shares of our common stock.

Series B Preferred Stock

  We currently have 100,000 shares of Series B Preferred Stock 
authorized, none of which are issued and outstanding. Shares of 
Series B Preferred Stock are nonredeemable and subordinate to any other 
series of preferred stock that is or may be issued by us.

  Shares of Series B Preferred Stock will be issued in Units, each of 
which is equivalent to 1/1000 of a share of Series B Preferred Stock.  
Each Unit will have a minimum preferential quarterly dividend of $0.01 
or any higher per share dividend declared on shares of our common 
stock. In the event of liquidation, the holder of a Unit will receive a 
preferred liquidation payment equal to the greater of $0.01 per Unit 
and the per share amount paid in respect of a share of our common 
stock.

  Each Unit will have one vote on all matters submitted to a vote of our 
stockholders, voting together with the shares of our common stock. In 
the event of any merger, consolidation or other transaction in which 
shares of our common stock are exchanged, each Unit will be entitled to 
receive the per share amount paid in respect of each share of our 
common stock. The rights of holders of the shares of Series B Preferred 
Stock with respect to dividends, liquidation and voting, and in the 
event of mergers and consolidations, are protected by antidilution 
provisions.

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

Rights Agreement

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

  The Rights are attached to all certificates representing outstanding 
shares of our common stock, and no separate Rights certificates have 
been distributed. The Rights will separate from shares of our common 
stock, 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 
l2b-2 of the General Rules and Regulations under the Securities Act) 
has acquired or otherwise obtained beneficial ownership (as defined in 
the Rights Agreement) of 15% or more of the then outstanding shares of 
our common stock (an "Acquiring Person"), or (ii) ten business days 
(or such later date as may be determined by action of the 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 shares of our common stock. Until the Distribution 
Date, (i) the Rights will be evidenced by our common stock certificates 
and will be transferred with and only with such stock certificates, 
(ii) new stock certificates issued after July 6, 1998 (also including 
shares distributed from treasury) will contain a notation incorporating 
the Rights Agreement by reference and (iii) the surrender for transfer 
of any certificates representing outstanding shares of our common stock 
will also constitute the transfer of the Rights associated with the 
shares of our common stock represented by such certificates.

  The Rights are not exercisable until the Distribution Date and will 
expire at the close of business on the tenth anniversary of the Rights 
Agreement unless earlier redeemed or exchanged by us as described 
below. Under certain circumstances the exercisability of the Rights may 
be suspended. In no event, however, will the Rights be exercisable 
prior to the expiration of the period in which they may be redeemed.

  As soon as practicable after the Distribution Date, Rights certificates 
will be mailed to holders of record of shares of our common stock as of 
the close of business on the Distribution Date and, thereafter, the 
separate Rights certificates alone will represent the Rights.

  If a person becomes an Acquiring Person, then each holder of a Right 
will thereafter have the right to receive, upon exercise, Units or, at 
the option of the Board of Directors, shares of our common stock (or, 
in certain circumstances, cash, property or other securities of 
Uniphase) having a value equal to two times the exercise price of the 
Right. The exercise price is the purchase price multiplied by the 
number of Units issuable upon exercise of a 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 
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) we are acquired in a merger or other 
business combination transaction and we are not the surviving 
corporation, (ii) any person merges with us and all or part of the 
shares of our common stock are converted or exchanged for securities, 
cash or property of Uniphase or any other person or (iii) 50% or more 
of our assets or earning power is sold or transferred, each holder of a 
Right (except 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 Right.

  The purchase price payable, and the number of Units issuable, upon 
exercise of the 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 Series B Preferred 
Stock, (ii) if holders of shares of the Series B Preferred Stock are 
granted certain rights or warrants to subscribe for shares of Series B 
Preferred Stock or convertible securities at less than the current 
market price of shares of the Series B Preferred Stock, or (iii) upon 
the distribution to the holders of shares of Series B Preferred Stock 
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. We are not required to issue fractional shares of 
Series B Preferred Stock (other than fractions which are integral 
multiples of a 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 one share of Series B Preferred Stock on the day of 
exercise.

  At any time until ten days following the Stock Acquisition Date, a 
majority of the Board of Directors may redeem the Rights in whole, but 
not in part, at a price of $0.01 per Right (subject to adjustment in 
certain events) (the "Rights Redemption Price") payable, at the 
election of the majority of the Board of Directors, in cash or shares 
of our common stock. Immediately upon the action of a majority of the 
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 Rights, the Rights will terminate and the only right 
of the holders of Rights will be to receive the Rights Redemption 
Price.

  We may at any time after there is an Acquiring Person, by action of a 
majority of the Board of Directors, exchange all or part of the then 
outstanding and exercisable Rights (other than Rights that shall have 
become null and void) for shares of our common stock pursuant to a 
one-for-one exchange ratio, as adjusted. Until a 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 Rights will not be 
taxable to stockholders or to us, stockholders may, depending upon the 
circumstances, recognize taxable income in the event that the Rights 
become exercisable for Units (or other consideration).

  Any provision of the Rights Agreement may be amended without the 
approval of our stockholders at any time prior to the Distribution 
Date. After the Distribution Date, the provisions of the 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 Rights (excluding the interests of any 
Acquiring Person), or to shorten or lengthen any time period under the 
Rights Agreement; provided, however, that no amendment may be made to 
adjust (i) the time period governing redemption at such time as the 
Rights are not redeemable or (ii) any other time period unless such 
lengthening is for the purpose of protecting, enhancing or clarifying 
the Rights of and/or benefiting, the holders of 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 Board of 
Directors.

  Upon completion of the combination with JDS, for purposes of the Rights 
Agreement, beneficial ownership of exchangeable shares will be treated 
as beneficial ownership of shares of our common stock and calculations 
of percentage ownership, the number of shares outstanding and related 
provisions will be made on a basis that treats the shares of our common 
stock and the exchangeable shares as though they were the same 
security.  In addition, on or prior to the consummation of our 
combination with JDS, the Rights Agreement will be amended to provide 
that (i) The Furukawa Electric Co., Ltd. (a substantial JDS 
shareholder) and its affiliates will not be "Acquiring Persons" as a 
result of Furukawa's direct or indirect acquisition of exchangeable 
shares or shares of our common stock pursuant to the combination, (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 shares of our common stock, 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 shares of our common stock 
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 shares of our common stock within 180 days of 
completion of the acquisition in which they are acquired.  

Special Voting Share

  The Board of Directors has designated one authorized share of Preferred 
Stock as a Special Voting Share, par value $0.001.  The Special Voting 
Share will be issued to the Trustee appointed under the Voting and 
Exchange Trust Agreement to be entered into the date of the 
consummation of our combination with JDS among us, JDS Uniphase Canada 
Ltd. and a voting trustee.  Except as otherwise required by law or our 
Certificate of Incorporation, 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 us or our affiliates, which votes 
may be exercised for the election of directors and on all other matters 
submitted to a vote of our stockholders. The holders of shares of our 
common stock 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 our Certificate of 
Incorporation.  The holder of the Special Voting Share will not be 
entitled to receive any dividends from us and, in the event of any 
liquidation, dissolution or winding up of Uniphase, will receive an 
amount equal to the par value of such share. At such time as there are 
no exchangeable shares outstanding not owned by us or our affiliates, 
and there are no shares of stock, debt, options or other agreements of 
JDS Uniphase Canada Ltd. that could give rise to the issuance of any 
exchangeable shares to any person (other than us or our affiliates), 
the Special Voting Share will be cancelled.

Delaware Law and Certain Certificate and Bylaw Provisions

  The following is a summary of certain aspects of Delaware law and 
certain provisions of our Certificate of Incorporation and Bylaws.

Prohibition on Certain Business Combinations

  We are 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 
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.

Limitations of Liability and Indemnification of Directors

  Our Certificate of Incorporation and Bylaws contain certain provisions 
relating to the limitation of liability and indemnification of 
directors and officers. Our Certificate of Incorporation 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, our Certificate of Incorporation and Bylaws 
provide that we shall indemnify our directors and officers to the 
fullest extent authorized by Delaware law.

Election of Directors

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

Meetings of Stockholders

  Our Certificate of Incorporation provides that stockholders can take 
action only at a duly called annual or special meeting of stockholders. 
Our Certificate of Incorporation prohibits our stockholders from taking 
action by written consent in lieu of a meeting. In addition, our 
Certificate of Incorporation provides that, subject to the rights of 
the holders of any shares having a preference over the shares of our 
common stock as to dividends or liquidation, special meetings of the 
stockholders can be called only by the Board of Directors, our Chairman 
of the Board or our Chief Executive Officer.  Stockholders are not 
permitted to call a special meeting or to require the 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.

PLAN OF DISTRIBUTION

Exchangeable Shares

  On the effective date of our combination with JDS, the following, among 
other things,  will occur:

     o the holders of JDS common shares (other than dissenting 
       shareholders) will initially receive 0.50855 of a Class B Non-
       Voting Preference Share of the capital stock of JDS Uniphase 
       Canada Ltd. for each JDS common share they hold;

     o immediately thereafter, each Class B Non-Voting Preference 
       Share held by Canadian residents will be transferred by the 
       holder at the holder's election, (i) to JDS Uniphase Canada 
       Ltd., a wholly-owned subsidiary of Uniphase, in exchange for 
       one exchangeable share, or (ii) to JDS Uniphase Nova Scotia 
       Company in exchange for one share of our common stock.  
       Holders of JDS common shares who are not Canadian residents 
       will receive one share of our common stock for each Class B 
       Non-Voting Preference Share they hold;

     o each Class B Non-Voting Preference Share held by a Canadian 
       resident who fails to properly make an election (other than 
       dissenting shareholders) will be transferred to JDS Uniphase 
       Canada Ltd in exchange for one exchangeable share;

     o JDS shareholders who dissent to the combination of Uniphase 
       and JDS will be entitled to receive the fair market value of 
       their JDS common shares; and

     o each option to purchase JDS common shares will become an 
       option to purchase shares of our common stock. The option will 
       provide for an exercise price per share of our common stock 
       equal to the per share exercise price of such option to 
       purchase JDS common shares immediately prior to the 
       combination divided by 0.50855 and converted into U.S. 
       dollars. Immediately prior to the combination, the JDS Board 
       of Directors may resolve to accelerate the vesting schedule 
       for all or any portion of the options to purchase JDS common 
       shares so that immediately following the combination, the 
       options to purchase shares of our common stock will be 
       immediately exercisable.

  We and our affiliates do not currently own any JDS common shares and 
are prohibited from acquiring any JDS common shares prior to the date 
of the combination pursuant to the transaction documents, except with 
the prior approval of JDS.

  Immediately following the combination, JDS will become an indirect 
subsidiary of Uniphase.  Based on the exchange ratio of 0.50855 shares 
of our common stock or exchangeable shares for each JDS common share, 
immediately following completion of the combination, the former holders 
of JDS common shares will hold an aggregate of approximately 39.7 
million exchangeable shares and shares of common stock.  Assuming all 
JDS common shares are exchanged for shares of common stock and based 
upon the number of JDS common shares and shares of our common stock 
outstanding as of January 27, 1999, immediately following completion of 
the combination, existing JDS shareholders would hold approximately 50% 
of our outstanding shares of common stock.

Procedures For Issuance of Our Common Stock

Election By Holders of Exchangeable Shares to Exchange Such Shares.

  Subject to the exercise by JDS Uniphase Nova Scotia Company of its 
overriding purchase right discussed below, holders of the exchangeable 
shares will be entitled at any time following the combination to 
require JDS Uniphase Canada Ltd. to redeem any or all of the 
exchangeable shares held by such holder in exchange for an equal number 
of shares of our common stock plus any declared and unpaid dividends on 
such shares of our common stock.  

  When a holder requests JDS Uniphase Canada Ltd. to redeem exchangeable 
shares, JDS Uniphase Nova Scotia Company will have an overriding right 
to purchase on the effective date of the redemption all but not less 
than all of the redeemed shares. 

  A holder may revoke its redemption request, in writing, at any time 
prior to the close of business on the business day preceding the 
effective date of the redemption, in which case the redeemed shares 
will neither be purchased by JDS Uniphase Nova Scotia Company nor be 
redeemed by JDS Uniphase Canada Ltd. 

  If, as a result of solvency requirements or applicable law, JDS 
Uniphase Canada Ltd. is not permitted to redeem all shares tendered by 
a redeeming holder, JDS Uniphase Canada Ltd. will redeem only those 
shares tendered by the holder (rounded down to a whole number of 
shares) permitted by law.   We will purchase the remaining tendered 
shares not redeemed by JDS Uniphase Canada Ltd.

Redemption of Exchangeable Shares.

  Subject to legal requirements and the right of JDS Uniphase Nova Scotia 
Company  to purchase the exchangeable shares, on a date selected by our 
Board of Directors which is no earlier than March 31, 2014, JDS 
Uniphase Canada Ltd. will redeem all but not less than all of the then 
outstanding exchangeable shares in exchange for an equal number of 
shares of our common stock plus any declared and unpaid dividends on 
such shares of our common stock. 

  JDS Uniphase Nova Scotia Company will have an overriding right to 
purchase on the date our Board of Directors selects, all but not less 
than all of the exchangeable shares then outstanding (other than 
exchangeable shares held by our affiliates) in exchange for an equal 
number of shares of our common stock plus any declared and unpaid 
dividends on such shares of our common stock.  Upon the exercise of 
this right, holders will be obligated to sell their exchangeable shares 
to JDS Uniphase Nova Scotia Company.

Early Redemption.

  JDS Uniphase Canada Ltd. has the right to redeem the exchangeable 
shares prior to March 31, 2014 in the following circumstances:

     o there being fewer than 992,372 exchangeable shares outstanding 
       (excluding exchangeable shares held by us and our affiliates), 
       provided that such number may be adjusted by the Board of 
       Directors of JDS Uniphase Canada Ltd. in certain 
       circumstances,

     o the occurrence of certain mergers involving us, provided that 
       the Board of Directors of JDS Uniphase Canada Ltd. determines 
       (1) that it is not reasonably practicable to substantially 
       replicate the terms and conditions of the exchangeable shares 
       in connection with the merger and (2) that the redemption of 
       the exchangeable shares is necessary to enable the completion 
       of the merger,

     o a proposal being made for certain voting events involving 
       exchangeable shares, provided that the Board of Directors of 
       JDS Uniphase Canada Ltd. determines that it is not reasonably 
       practicable to accomplish the business purpose intended by the 
       voting event in any other commercially reasonable manner that 
       does not result in an voting event, or

     o the failure by the holders of the exchangeable shares to 
       approve or disapprove, as applicable, certain voting events.

Liquidation of JDS Uniphase Canada

  In the event of the liquidation, dissolution or winding-up of JDS 
Uniphase Canada Ltd., holders of the exchangeable shares will have, 
subject to applicable law, preferential rights to receive from JDS 
Uniphase Canada Ltd. a liquidation amount of one share of our common 
stock plus the amount of any declared but unpaid dividends on such 
share for each exchangeable share they hold.  Upon the occurrence of 
such liquidation, dissolution or winding-up, JDS Uniphase Nova Scotia 
Company will have an overriding liquidation call right to purchase all 
of the outstanding exchangeable shares (other than exchangeable shares 
held by our affiliates).

  Upon the occurrence and during the continuance of an event of 
insolvency involving JDS Uniphase Canada Ltd., each holder of 
exchangeable shares (other than our affiliates) may exercise the 
exchange right with respect to any or all of the exchangeable shares, 
thereby requiring us to purchase such exchangeable shares from the 
holder.  

Liquidation of Uniphase.

Upon the occurrence of an event of insolvency involving us, in order 
for the holders of the exchangeable shares to participate on a pro rata 
basis with holders of shares of our common stock, each exchangeable 
share (other than those held by our affiliates) will automatically be 
exchanged for an equivalent number of shares of our common stock.

                         INCOME TAX CONSIDERATIONS

Canadian Federal Income Tax Considerations

  In the opinion of Tory Tory DesLauriers & Binnington, Canadian counsel 
for Uniphase, the following is a summary of the principal Canadian 
federal income tax considerations under the Income Tax Act (Canada) in 
respect of the exchange of exchangeable shares for shares of our common 
stock and the holding of shares of our common stock generally 
applicable to holders of exchangeable shares who, for purposes of the 
Income Tax Act (Canada) and any relevant bilateral tax treaty, and at 
all relevant times, is resident or deemed to be resident in Canada 
while holding exchangeable shares or shares of our common stock, hold 
their exchangeable shares, and will hold their shares of our common 
stock, as capital property and deal at arm's length with Uniphase, JDS 
Uniphase Nova Scotia Company and JDS Uniphase Canada Ltd.

  Exchangeable shares and shares of our common stock 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.  Shareholders whose 
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 Income Tax Act (Canada). 
Shareholders who do not hold their exchangeable shares as capital 
property should consult their own tax advisors regarding their 
particular circumstances. In addition, the mark-to-market rules 
contained in the Income Tax Act (Canada) 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 exchangeable shares or shares of our common stock as capital 
property for the purposes of the  Income Tax Act (Canada).  
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 Income Tax Act 
(Canada), 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 prospectus. This summary takes into 
account all specific proposals to amend the Income Tax Act (Canada) and 
regulations publicly announced by the Canadian Minister of Finance, 
although no assurance can be given that such 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 Income Tax Act (Canada), all amounts relating 
to the acquisition, holding or disposition of shares of our common 
stock 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. 

Redemption or Exchange of Exchangeable Shares

  On the redemption (including a retraction) of an exchangeable share by 
JDS Uniphase Canada Ltd., the holder of the 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 
our shares of common stock (including any related Uniphase rights) 
received by the shareholder from JDS Uniphase Canada Ltd. on the 
redemption plus the full amount of all dividends, if any, declared and 
unpaid on each exchangeable share held by the holder on any dividend 
record date occurring prior to such time (the "Dividend Amount") 
exceeds the paid-up capital (for purposes of the Income Tax Act 
(Canada)) 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 below under the heading "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 any 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 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 JDS Uniphase Nova Scotia Company or 
Uniphase for shares of our common stock (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 shares of 
our common stock (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. 

  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 JDS Uniphase Canada Ltd. or 
by way of purchase of the exchangeable shares by Uniphase or JDS 
Uniphase Nova Scotia Company. As described above, the Canadian federal 
income tax consequences of a redemption differ from those of a 
purchase. 

Dividends on Exchangeable Shares

  In the case of a 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 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 shareholder that is a corporation, other 
than a "specified financial institution" as defined in the Income Tax 
Act (Canada), 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 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 Toronto Stock Exchange) 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 or deemed to be paid on an exchangeable share, 
then subject to the exemption described below, dividends received or 
deemed to be received by a 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 Income Tax Act (Canada). A 
corporation is a specified financial institution for purposes of the 
Income Tax Act (Canada) 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 deemed to be 
received by a corporate shareholder. This denial of the dividend 
deduction for a 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 Toronto Stock Exchange), Uniphase and JDS 
Uniphase Nova Scotia Company are "related" to JDS Uniphase Canada Ltd. 
for the purposes of the Income Tax Act (Canada) 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. 

  A shareholder that is a "private corporation" (as defined in the 
Income Tax Act (Canada)) 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 Income Tax Act (Canada) to pay a refundable tax of 331/3% 
on dividends received or deemed to be received on the exchangeable 
shares to the extent that such dividends are deductible in computing 
the shareholder's taxable income. A shareholder that is a 
"Canadian-controlled private corporation" (as defined in the Income 
Tax Act (Canada)) 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 Income Tax Act 
(Canada). Accordingly, JDS Uniphase Canada Ltd. will be subject to a 66 
2/3% tax under Part VI.I of the Income Tax Act (Canada) 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 Income Tax Act (Canada). 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 Income Tax Act (Canada).

Acquisition and Disposition of Shares of Our Common Stock

  The cost of the shares of our common stock  received on the retraction, 
redemption or exchange of an exchangeable share will be equal to the 
fair market value of such shares of our common stock at the time of 
such event, to be averaged with the adjusted cost base of any other 
shares of our common stock held at that time by the holder as capital 
property. 

  A disposition or deemed disposition of shares of our common stock 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 shares of our common stock immediately before the 
disposition. 

Taxation of Capital Gain or Capital Loss

  Three-quarters of any capital gain (the "taxable capital gain") 
realized by a shareholder will be included in the 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 
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 Income Tax Act (Canada). 

  Capital gains realized by an individual or trust, other than certain 
trusts, may give rise to alternative minimum tax under the Income Tax 
Act (Canada). A shareholder that is a Canadian-controlled private 
corporation (as defined in the Income Tax Act (Canada)) may be liable 
to pay an additional refundable tax of 6 2/3% on taxable capital gains. 

  If the holder of an 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 Income Tax Act (Canada). Similar rules 
may apply where a corporation is a member of a partnership or a 
beneficiary of a trust that owns 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. 

Dividends on Shares of Our Common Stock

  Dividends on our shares of common stock will be required to be included 
in the recipient's income for the purposes of the Income Tax Act 
(Canada). Such dividends received by a shareholder who is an individual 
will not be subject to the gross-up and dividend tax credit rules in 
the Income Tax Act (Canada). A 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 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 Income Tax Act (Canada). 
See the commentary below under the heading "United States Federal Tax 
Considerations".

United States Federal Tax Considerations for JDS Shareholders

  In the opinion of Morrison & Foerster LLP, U.S. counsel for Uniphase, 
the following is a summary of the material United States federal income 
tax considerations applicable to non-U.S. holders who receive shares of 
our common stock in exchange for exchangeable shares.  For purposes of 
this discussion, a U.S. holder is a beneficial owner of JDS common 
shares who or that is (1) a citizen or resident of the United States, 
(2) a corporation, partnership or other entity taxable as a corporation 
created or organized in or under the laws of the United States or of 
any political subdivision thereof, (3) an estate the income of which is 
subject to United States federal income taxation regardless of its 
source or (4) 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 Internal Revenue 
Code of 1986, as amended (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 JDS common shares other than a U.S. holder. 

  This summary does not discuss all United States federal income tax 
considerations that may be relevant to non-U.S. holders in light of 
their particular circumstances or to non-U.S. holders that may be 
subject to special treatment under United States federal income tax 
laws (for example, individuals who were formerly citizens or residents 
of the United States, 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, and holders who acquired JDS common 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 options to purchase JDS common shares, nor does it address any 
aspects of non-U.S., 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 Internal Revenue Service (the "IRS") regarding 
the tax consequences of the transactions described herein.

  The discussion does not address U.S. holders who are also Canadian 
residents and who receive exchangeable shares.  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 
our common shares.

  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 non-U.S. 
tax consequences of the described transactions in their particular 
circumstances.

Exchangeable Shares

  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 exchange of exchangeable shares for shares of our common stock, 
unless such gain is effectively connected with a United States trade or 
business of the non-U.S. holder, attributable to a permanent 
establishment of the non-U.S. holder in the United States 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.

Shares of Our Common Stock

Dividends on Shares of Our Common Stock. Dividends (other than 
dividends of common stock) paid to a non-U.S. holder of shares of our 
common stock 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 
(1) effectively connected with the conduct of a trade or business of 
the non-U.S. holder within the United States, or (2) 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.  Under the U.S.-Canada Tax 
Convention, the withholding rate on dividends for eligible Canadian 
residents is generally 15%. 

Sale or Exchange of Shares of Our Common Stock. 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 shares of our common stock unless (1) the gain 
is effectively connected with a trade or business of the non-U.S. 
holder in the United States; (2) 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 (3) (a) we are or have been during certain periods preceding the 
disposition a "U.S. real property holding corporation" for United 
States federal income tax purposes (which we do not believe we are or 
are likely to become), and (b) assuming that shares of our common stock 
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 our outstanding common 
stock.  Generally, an individual who is a resident of Canada for 
purposes of the U.S.-Canada Income Tax Convention will not be subject 
to U.S. tax on the sale or other disposition of shares of our common 
stock.

Backup Withholding and Information Reporting

Dividends.  Until January 1, 2001, United States backup withholding tax 
generally will not apply to dividends paid on our common shares to a 
non-U.S. holder at an address outside the United States. We 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 Shares of Our Common Stock. Upon the sale or other 
disposition of shares of our common stock 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 shares of our common stock 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 (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.

  The IRS has 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 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 shares of our common stock.

United States Estate Tax Consequences

  Shares of our common stock owned at the time of his or her death by an 
individual non-U.S. holder will be includable in his or her gross 
estate for United States federal estate tax purposes and, subject to 
certain credits, may be subject to United States federal estate tax, 
unless an applicable income or estate tax treaty provides otherwise.  
Under certain circumstances, Article XXXIXB of the U.S.-Canadian Income 
Tax Convention limits the application of the U.S. estate tax to 
Canadian residents.  Accordingly, Canadian residents are urged to 
consult their tax advisors regarding the possible application of the 
U.S. estate tax.

are governed by Delaware law.  Under Section 145 of the General 
Corporation Law of the State of Delaware, Uniphase has broad powers to 
indemnify its directors and officers against liabilities that may incur 
in such capacities, including liabilities under the Securities Act of 
1933, as amended (the "Securities Act"). Uniphase's Bylaws also 
provide for mandatory indemnification of its directors and executive 
officers, and permissive indemnification of its employees and agents, 
to the fullest extent permissible under Delaware law.

  Uniphase's Certificate of Incorporation provides that the liability of 
its directors for monetary damages shall be eliminated to the fullest 
extent permissible under Delaware law. Pursuant to Delaware law, this 
includes elimination of liability for monetary damages for breach of 
the directors' fiduciary duty of care to Uniphase and its stockholders. 
These provisions do not eliminate the directors' duty of care and, in 
appropriate circumstances, equitable remedies such as injunctive or 
other forms of non-monetary relief will remain available under Delaware 
law. In addition, each director will continue to be subject to 
liability for breach of the director's duty of loyalty to the Company, 
for acts of omissions not in good faith or involving intentional 
misconduct, for knowing violations of law, for any transaction from 
which the director derived an improper personal benefit, and for 
payment of dividends or approval of stock repurchases or redemptions 
that are unlawful under Delaware law. The provision also does not 
affect a director's responsibilities under any other laws, such as the 
federal securities laws or state or federal environmental laws.

  Uniphase has entered into agreements with its directors and certain of 
its executive officers that require Uniphase to indemnify such persons 
against expenses, judgments, fines, settlements and other amounts 
actually and reasonably incurred (including expenses of a derivative 
action) in connection with any proceeding, whether actual or 
threatened, to which any such person may be made a party by reason of 
the fact that such person is or was a director or officer of Uniphase 
or any of its affiliated enterprises, provided such person acted in 
good faith and in a manner such person reasonably believed to be in or 
not opposed to the best interests of Uniphase and, with respect to any 
criminal proceeding, had no reasonable cause to believe his or her 
conduct was unlawful. The indemnification agreement also sets forth 
certain procedures that will apply in the event of a claim for 
indemnification thereunder.

  Uniphase has obtained a policy of directors' and officers' liability 
insurance that insures Uniphase's directors and officers against the 
cost of defense, settlement or payment of a judgment under certain 
circumstances.

Item 17. Undertakings 

The undersigned Registrant hereby undertakes: 

(1)  To file, during any period in which offers or sales are being 
     made, a post-effective amendment to this registration statement: 

     (i) To include any prospectus required by Section 10(a)(3) of 
         the Securities Act of 1933; 

     (ii) To reflect in the prospectus any facts or events arising 
          after the effective date of the registration statement (or 
          the most recent post-effective amendment thereof) which, 
          individually or in the aggregate, represent a fundamental 
          change in the information set forth in this registration 
          statement. Notwithstanding the foregoing, any increase or 
          decrease in volume of securities offered (if the total 
          dollar value of securities offered would not exceed that 
          which was registered) any deviation from the low or high 
          and of the estimated maximum offering price may be 
          reflected in the form of prospectus filed with the 
          Commission pursuant to Rule 424(b) if, in the aggregate 
          changes in volume and price represent no more than a 20 
          percent change in the maximum aggregate offering price set 
          forth in the "Calculation of Registration Fee" table in 
          the effective registration statement; and 

     (iii)To include any material information with respect to the 
          plan of distribution not previously disclosed in this 
          registration statement or any material change to such 
          information in this registration statement; provided, 
          however, that subparagraphs (i) and (ii) do not apply if 
          the information required to be included in a post-effective 
          amendment by those paragraphs is contained in the periodic 
          reports filed by the Registrant pursuant to Section 13 or 
          Section 15(d) of the Securities Exchange Act of 1934 that 
          are incorporated by reference in this registration 
          statement. 

(2)  That, for the purpose of determining any liability under the 
     Securities Act of 1933, each such post-effective amendment shall 
     be deemed to be a new registration statement relating to the 
     securities offered herein, and the offering of such securities at 
     that time shall be deemed to be the initial bona fide offering 
     thereof. 

(3)  To remove from registration by means of a post-effective 
     amendment any of these securities being registered which remain 
     unsold at the termination of the offering. 

  The undersigned Registrant hereby further undertakes that, for the 
purposes of determining any liability under the Securities Act of 1933, 
each filing of the Registrant's annual reports pursuant to Section 
13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, 
when applicable, each filing of an employee benefit plan's annual 
report pursuant to Section 15(d) of the Securities Exchange Act of 
1934) that is incorporated by reference to this registration statement 
shall be deemed to be a new registration statement relating to the 
securities offered therein, and the offering of such securities at that 
time shall be deemed to be the initial bona fide offering thereof. 

  The undersigned Registrant hereby further undertakes that: 

(1)  For purposes of determining any liability under the Securities 
     Act of 1933, the information omitted from the form of prospectus 
     filed as part of this registration statement in reliance under 
     Rule 430A and contained in a form of prospectus filed by the 
     Registrant pursuant to Rule 424(b)(1) or (4), or 497(h) under the 
     Securities Act of 1933 shall be deemed to be part of this 
     registration statement as of the time it was declared effective. 

(2)  For the purpose of determining any liability under the Securities 
     Act of 1933, each post-effective amendment that contains a form 
     of prospectus shall be deemed to be a new registration statement 
     relating to the securities offered therein, and the offering of 
     such securities at that time shall be deemed to be the initial 
     bona fide offering thereof. 

  Insofar as indemnification for liabilities arising under the Securities 
Act of 1933 may be permitted to directors, officers and controlling 
persons of the Registrant pursuant to the provisions described under 
Item 15 of this registration statement, or otherwise (other than 
insurance), the Registrant has been advised that in the opinion of the 
Securities and Exchange Commission such indemnification is against 
public policy as expressed in such Act and is, therefore, 
unenforceable. In the event that a claim for indemnification against 
such liabilities (other than the payment by the Registrant of expenses 
incurred or paid by a director, officer or controlling person of the 
Registrant in the successful defense of any action suit or proceeding) 
is asserted by such director, officer or controlling person in 
connection with the securities being registered, the Registrant will, 
unless in the opinion of its counsel the matter has been settled by 
controlling precedent, submit to a court of appropriate jurisdiction 
the question whether such indemnification by it is against public 
policy as expressed in such Act and will be governed by the final 
adjudication of such issue.

of California on May 19, 1999.
