Program, the unpurchased Shares which were subject thereto shall become
available for future grant or sale under the Plan (unless the Plan has
terminated); PROVIDED, however, that Shares that have actually been issued under
the Plan shall not be returned to the Plan and shall not become available for
future distribution under the Plan, except that if unvested Shares are
repurchased by the Company at their original purchase price, and the original
purchaser of such Shares did not receive any benefits of ownership of such
Shares, such Shares shall become available for future grant under the Plan. For
purposes of the preceding sentence, voting rights shall not be considered a
benefit of Share ownership.

         4.       ADMINISTRATION OF THE PLAN.

                  (a) INITIAL PLAN PROCEDURE. Prior to the date, if any, upon

                  (b) PLAN PROCEDURE AFTER THE DATE, IF ANY, UPON WHICH THE
COMPANY BECOMES SUBJECT TO THE EXCHANGE ACT.

                           (i)      ADMINISTRATION WITH RESPECT TO DIRECTORS AND
OFFICERS. With respect to grants of Options to Employees who are also Officers
or directors of the Company, the Plan shall be administered by (A) the Board if

under the Exchange Act or any successor thereto ("Rule 16b-3") with respect to a
plan intended to qualify thereunder as a discretionary plan, or (B) a Committee
designated by the Board to administer the Plan, which Committee shall be
constituted in such a manner as to permit the Plan to comply with Rule 16b-3
with respect to a plan intended to qualify thereunder as a discretionary plan.
Once appointed, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board. From time to time the Board may
increase the size of the Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies, however caused, and remove all members of the
Committee and thereafter directly administer the Plan, all to the extent
permitted by Rule 16b-3 with respect to a plan intended to qualify thereunder as
a discretionary plan.

                           (ii)     MULTIPLE ADMINISTRATIVE BODIES. If permitted
by Rule 16b-3, the Plan may be administered by different bodies with respect to

                                       3




                           (iii)    ADMINISTRATION WITH RESPECT TO
CONSULTANTS AND OTHER EMPLOYEES. With respect to grants of Options to
Employees or Consultants who are neither directors nor Officers of the
Company, the Plan shall be administered by (A) the Board or (B) a committee
designated by the Board, which committee shall be constituted in such a
manner as to satisfy the legal requirements relating to the administration of
incentive stock option plans, if any, of California corporate and securities
laws, of the Code, and of any applicable stock exchange (the "Applicable
Laws"). Once appointed, such Committee shall continue to serve in its
designated capacity until otherwise directed by the Board. From time to time
the Board may increase the size of the Committee and appoint additional
members thereof, remove members (with or without cause) and appoint new
members in substitution therefor, fill vacancies, however caused, and remove
all members of the Committee and thereafter directly administer the Plan, all
to the extent permitted by the Applicable Laws.

                  (c) POWERS OF THE ADMINISTRATOR. Subject to the provisions of
the Plan and, in the case of a Committee, the specific duties delegated by the
Board to such Committee, and subject to the approval of any relevant
authorities, including the approval, if required, of any stock exchange upon
which the Common Stock is listed, the Administrator shall have the authority, in
its discretion:

                           (i)      to determine the Fair Market Value of the
Common Stock, in accordance with Section 2(k) of the Plan;

                           (ii)     to select the Consultants and Employees to
whom Options may from time to time be granted hereunder;

                           (iii)    to determine whether and to what extent
Options are granted hereunder;

                           (iv)     to determine the number of shares of Common
Stock to be covered by each such award granted hereunder;

                           (v)      to approve forms of agreement for use under
the Plan;

                           (vi)     to determine the terms and conditions of any
award granted hereunder;

                           (vii)    to determine whether and under what
circumstances an Option may be settled in cash under subsection 9(f) instead of
Common Stock;

                           (viii)   to reduce the exercise price of any Option
to the then current Fair Market Value if the Fair Market Value of the Common
Stock covered by such Option has declined since the date the Option was granted;
and

                           (ix)     to construe and interpret the terms of the
Plan and awards granted pursuant to the Plan.

                  (d) EFFECT OF ADMINISTRATOR'S DECISION. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options.


                                       4



         5.       ELIGIBILITY.

                  (a) Nonstatutory Stock Options may be granted to Employees and
Consultants. Incentive Stock Options may be granted only to Employees. An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options.

                  (b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value:

                           (i)      of Shares subject to an Optionee's Incentive
Stock Options granted by the Company, any Parent or Subsidiary, which

                           (ii)     become exercisable for the first time during
any calendar year (under all plans of the Company or any Parent or Subsidiary)

exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock
Options. For purposes of this Section 5(b), Incentive Stock Options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the Shares shall be determined as of the time the Option with respect
to such Shares is granted.

                  (c) The Plan shall not confer upon any Optionee any right with
respect to continuation of employment or consulting relationship with the
Company, nor shall it interfere in any way with his or her right or the
Company's right to terminate his or her employment or consulting relationship at
any time, with or without cause.

                  (d) Upon the Company or a successor corporation issuing any
class of common equity securities required to be registered under Section 12 of
the Exchange Act or upon the Plan being assumed by a corporation having a class
of common equity securities required to be registered under Section 12 of the
Exchange Act, the following limitations shall apply to grants of Options to
Employees:

                           (i)      No Employee shall be granted, in any fiscal
year of the Company, Options to purchase more than 500,000 Shares.

                           (ii)     The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 11.

                           (iii)    If an Option is canceled in the same fiscal
year of the Company in which it was granted (other than in connection with a
transaction described in Section 11), the cancelled Option will be counted
against the limit set forth in Section 11. For this purpose, if the exercise
price of an Option is reduced, the transaction will be treated as a cancellation
of the Option and the grant of a new Option.

         6.       TERM OF PLAN. The Plan shall become effective upon the
earlier to occur of its adoption by the Board of Directors or its approval by
the shareholders of the Company, as described


                                       5



in Section 17 of the Plan. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 13 of the Plan.

         7.       TERM OF OPTION. The term of each Option shall be the term
stated in the Option Agreement; provided, however, that the term shall be no
more than ten (10) years from the date of grant thereof. However, in the case
of an Incentive Stock Option granted to an Optionee who, at the time the
Option is granted, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or
Subsidiary, the term of the Option shall be five (5) years from the date of
grant thereof or such shorter term as may be provided in the Option Agreement.

         8.       OPTION EXERCISE PRICE AND CONSIDERATION.

                  (a) The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Board, but shall be subject to the following:

                           (i)      In the case of an Incentive Stock Option

                                    (A)      granted to an Employee who, at the
time of the grant of such Incentive Stock Option, owns stock representing more
than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the per Share exercise price shall be no
less than 110% of the Fair Market Value per Share on the date of grant.

                                    (B)      granted to any Employee other than
an Employee described in the preceding paragraph, the per Share exercise price
shall be no less than 100% of the Fair Market Value per Share on the date of
grant.

                           (ii)     In the case of a Nonstatutory Stock Option

                                    (A)      granted to a person who, at the
time of the grant of such Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of the grant.

                                    (B)      granted to any person, the per
Share exercise price shall be no less than 85% of the Fair Market Value per
Share on the date of grant.

                  (b) The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option have been owned by the Optionee for more
than six months on the date of surrender and (y) have a Fair Market Value on the
date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised, (5) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
the broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price, or (6) any combination of the foregoing


                                       6





methods of payment. In making its determination as to the type of
consideration to accept, the Board shall consider if acceptance of such
consideration may be reasonably expected to benefit the Company.

         9.       EXERCISE OF OPTION.

                  (a) PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any
Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Board, including performance criteria with
respect to the Company and/or the Optionee, and as shall be permissible under
the terms of the Plan, but in no case at a rate of less than 20% per year over
five (5) years from the date the Option is granted.

                           An Option may not be exercised for a fraction of a
Share.

                           An Option shall be deemed to be exercised when
written notice of such exercise has been given to the Company in accordance with
the terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Board, consist
of any consideration and method of payment allowable under Section 8(b) of the
Plan. Until the issuance (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

                           Exercise of an Option in any manner shall result in a
decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

                  (b) TERMINATION OF EMPLOYMENT OR CONSULTING RELATIONSHIP. In
the event of termination of an Optionee's Continuous Status as an Employee or
Consultant with the Company (but not in the event of an Optionee's change of
status from Employee to Consultant (in which case an Employee's Incentive Stock
Option shall automatically convert to a Nonstatutory Stock Option on the
ninety-first (91st) day following such change of status) or from Consultant to
Employee), such Optionee may, but only within such period of time as is
determined by the Administrator, of at least thirty (30) days, with such
determination in the case of an Incentive Stock Option not exceeding three (3)
months after the date of such termination (but in no event later than the
expiration date of the term of such Option as set forth in the Option
Agreement), exercise his or her Option to the extent that Optionee was entitled
to exercise it at the date of such termination. To the extent that Optionee was
not entitled to exercise the Option at the date of such termination, or if
Optionee does not exercise such Option to the extent so entitled within the time
specified herein, the Option shall terminate.

                  (c) DISABILITY OF OPTIONEE. In the event of termination of an
Optionee's consulting relationship or Continuous Status as an Employee as a
result of his or her disability,


                                       7



Optionee may, but only within twelve (12) months from the date of such
termination (and in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise the Option to the
extent otherwise entitled to exercise it at the date of such termination;
provided, however, that if such disability is not a "disability" as such term
is defined in Section 22(e)(3) of the Code, in the case of an Incentive Stock
Option such Incentive Stock Option shall automatically convert to a
Nonstatutory Stock Option on the day three months and one day following such
termination. To the extent that Optionee is not entitled to exercise the
Option at the date of termination, or if Optionee does not exercise such
Option to the extent so entitled within the time specified herein, the Option
shall terminate, and the Shares covered by such Option shall revert to the
Plan.

                  (d) DEATH OF OPTIONEE. In the event of the death of an
Optionee, the Option may be exercised at any time within twelve (12) months
following the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Notice of Grant), by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent that the Optionee was entitled to
exercise the Option at the date of death. If, at the time of death, the Optionee
was not entitled to exercise his or her entire Option, the Shares covered by the
unexercisable portion of the Option shall immediately revert to the Plan. If,
after death, the Optionee's estate or a person who acquired the right to
exercise the Option by bequest or inheritance does not exercise the Option
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

                  (e) RULE 16b-3. Options granted to persons subject to Section
16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

                  (f) BUYOUT PROVISIONS. The Administrator may at any time offer
to buy out for a payment in cash or Shares, an Option previously granted, based
on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

         10. NON-TRANSFERABILITY OF OPTIONS. Options may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

         11.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

                  (a) CHANGES IN CAPITALIZATION. Subject to any required action
by the shareholders of the Company, the number of shares of Common Stock covered
by each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not


                                       8




be deemed to have been "effected without receipt of consideration." Such
adjustment shall be made by the Board, whose determination in that respect
shall be final, binding and conclusive. Except as expressly provided herein,
no issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or
price of shares of Common Stock subject to an Option.

                  (b) DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, the Board shall notify the Optionee
at least fifteen (15) days prior to such proposed action. To the extent it has
not been previously exercised, the Option will terminate immediately prior to
the consummation of such proposed action.

                  (c) MERGER. In the event of a merger of the Company with or
into another corporation, the Option may be assumed or an equivalent option may
be substituted by such successor corporation or a parent or subsidiary of such
successor corporation. If, in such event, the Option is not assumed or
substituted, the Option shall terminate as of the date of the closing of the
merger. For the purposes of this paragraph, the Option shall be considered
assumed if, following the merger, the option confers the right to purchase, for
each Share of Optioned Stock subject to the Option immediately prior to the
merger, the consideration (whether stock, cash, or other securities or property)
received in the merger by holders of Common Stock for each Share held on the
effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding Shares); provided, however, that if such consideration received
in the merger was not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon the exercise of the Option for
each Share of Optioned Stock subject to the Option to be solely common stock of
the successor corporation or its Parent equal in fair market value to the per
share consideration received by holders of Common Stock in the merger.

         12. TIME OF GRANTING OPTIONS. The date of grant of an Option shall, for
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Board. Notice
of the determination shall be given to each Employee or Consultant to whom an
Option is so granted within a reasonable time after the date of such grant.

         13.      AMENDMENT AND TERMINATION OF THE PLAN.

                  (a) AMENDMENT AND TERMINATION. The Board may at any time
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made which would impair the rights of any
Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with Rule 16b-3 under
the Exchange Act or with Section 422 of the Code (or any other applicable law or
regulation, including the requirements of the NASD or an established stock
exchange), the Company shall obtain shareholder approval of any Plan amendment
in such a manner and to such a degree as required.

                  (b) EFFECT OF AMENDMENT OR TERMINATION. Any such amendment or
termination of the Plan shall not affect Options already granted, and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between


                                       9



the Optionee and the Board, which agreement must be in writing and signed by
the Optionee and the Company.

         14.      CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be
issued pursuant to the exercise of an Option unless the exercise of such
Option and the issuance and delivery of such Shares pursuant thereto shall
comply with all relevant provisions of law, including, without limitation,
the Securities Act of 1933, as amended, the Exchange Act, the rules and
regulations promulgated thereunder, and the requirements of any stock
exchange upon which the Shares may then be listed, and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

                  As a condition to the exercise of an Option, the Company may
require the person exercising such Option to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

         15.      RESERVATION OF SHARES. The Company, during the term of this
Plan, will at all times reserve and keep available such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.

                  The inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority shall not have been
obtained.

         16.      AGREEMENTS. Options shall be evidenced by written
agreements in such form as the Board shall approve from time to time.

         17.      SHAREHOLDER APPROVAL. Continuance of the Plan shall be
subject to approval by the shareholders of the Company within twelve (12)
months before or after the date the Plan is adopted. Such shareholder
approval shall be obtained in the degree and manner required under applicable
state and federal law and the rules of any stock exchange upon which the
Common Stock is listed.

         18.      INFORMATION TO OPTIONEES AND PURCHASERS. The Company shall
provide to each Optionee, not less frequently than annually, copies of annual
financial statements. The Company shall also provide such statements to each
individual who acquires Shares pursuant to the Plan while such individual
owns such Shares. The Company shall not be required to provide such
statements to key employees whose duties in connection with the Company
assure their access to equivalent information.

         Unless otherwise defined herein, the terms defined in the Plan shall
have the same defined meanings in this Option Agreement.

II.      AGREEMENT

         1. GRANT OF OPTION. cadMOS Design Technology, Inc., a California
corporation (the "Company"), hereby grants to the Optionee named in the Notice
of Grant (the "Optionee"), an option (the "Option") to purchase the total number
of shares of Common Stock (the "Shares") set forth in the Notice of Grant, at
the exercise price per share set forth in the Notice of Grant (the "Exercise
Price") subject to the terms, definitions and provisions of the 1997 Stock
Option Plan (the "Plan")


                                       11



adopted by the Company, which is incorporated herein by reference. Unless
otherwise defined herein, the terms defined in the Plan shall have the same
defined meanings in this Option.

                 If designated in the Notice of Grant as an Incentive Stock
Option ("ISO"), this Option is intended to qualify as an Incentive Stock Option
as defined in Section 422 of the Code. However, if this Option is intended to be
an Incentive Stock Option, to the extent that it exceeds the $100,000 rule of
Code Section 422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

         2. EXERCISE OF OPTION. This Option shall be exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Grant and with
the provisions of Section 9 of the Plan as follows:

                  (i)      RIGHT TO EXERCISE.

                           (a)      This Option may not be exercised for a
fraction of a Share.

                           (b)      In the event of Optionee's death, disability
or other termination of the employment or consulting relationship, the
exercisability of the Option is governed by Sections 6, 7 and 8 below, subject
to the limitation contained in subsection 2(i)(c).

                           (c)      In no event may this Option be exercised
after the date of expiration of the term of this Option as set forth in the
Notice of Grant.

                 (ii)      METHOD OF EXERCISE. This Option shall be
exercisable by written notice (in the form attached as Exhibit A) which shall
state the election to exercise the Option, the number of Shares in respect of
which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such shares
of Common Stock as may be required by the Company pursuant to the provisions
of the Plan. Such written notice shall be signed by the Optionee and shall be
delivered in person or by certified mail to the Secretary of the Company. The
written notice shall be accompanied by payment of the Exercise Price. This
Option shall be deemed to be exercised upon receipt by the Company of such
written notice accompanied by the Exercise Price.

                 No Shares will be issued pursuant to the exercise of an Option
unless such issuance and such exercise shall comply with all relevant provisions
of law and the requirements of any stock exchange upon which the Shares may then
be listed. Assuming such compliance, for income tax purposes the Shares shall be
considered transferred to the Optionee on the date on which the Option is
exercised with respect to such Shares.

         3. OPTIONEE'S REPRESENTATIONS. In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended, at the time this Option is exercised,
Optionee shall, if required by the Company, concurrently with the exercise of
all or any portion of this Option, deliver to the Company his or her Investment
Representation Statement in the form attached hereto as Exhibit B, and shall
read the applicable rules of the Commissioner of Corporations attached to such
Investment Representation Statement.


                                       12




         4.       METHOD OF PAYMENT. Payment of the Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

                 (i)     cash; or

                 (ii)    check; or

                 (iii)   surrender of other shares of Common Stock of the
Company which (A) in the case of Shares acquired pursuant to the exercise of
a Company option, have been owned by the Optionee for more than six (6)
months on the date of surrender, and (B) have a Fair Market Value on the date
of surrender equal to the Exercise Price of the Shares as to which the Option
is being exercised; or

                 (iv)    delivery of a properly executed exercise notice
together with such other documentation as the Administrator and the broker,
if applicable, shall require to effect an exercise of the Option and delivery
to the Company of the sale or loan proceeds required to pay the Exercise
Price.

         5.       RESTRICTIONS ON EXERCISE. This Option may not be exercised
until such time as the Plan has been approved by the shareholders of the
Company, or if the issuance of such Shares upon such exercise or the method
of payment of consideration for such shares would constitute a violation of
any applicable federal or state securities or other law or regulation,
including any rule under Part 207 of Title 12 of the Code of Federal
Regulations ("Regulation G") as promulgated by the Federal Reserve Board. As
a condition to the exercise of this Option, the Company may require Optionee
to make any representation and warranty to the Company as may be required by
any applicable law or regulation.

         6.       TERMINATION OF RELATIONSHIP. In the event an Optionee's
Continuous Status as an Employee or Consultant terminates, Optionee may, to
the extent otherwise so entitled at the date of such termination (the
"Termination Date"), exercise this Option during the Termination Period set
out in the Notice of Grant. To the extent that Optionee was not entitled to
exercise this Option at the date of such termination, or if Optionee does not
exercise this Option within the time specified herein, the Option shall
terminate.

         7.       DISABILITY OF OPTIONEE. Notwithstanding the provisions of
Section 6 above, in the event of termination of an Optionee's consulting
relationship or Continuous Status as an Employee as a result of his or her
disability, Optionee may, but only within six (6) months from the date of
such termination (and in no event later than the expiration date of the term
of such Option as set forth in the Option Agreement), exercise the Option to
the extent otherwise entitled to exercise it at the date of such termination;
provided, however, that if such disability is not a "disability" as such term
is defined in Section 22(e)(3) of the Code, in the case of an Incentive Stock
Option such Incentive Stock Option shall automatically convert to a
Nonstatutory Stock Option on the day three months and one day following such
termination. To the extent that Optionee was not entitled to exercise the
Option at the date of termination, or if Optionee does not exercise such
Option to the extent so entitled within the time specified herein, the Option
shall terminate, and the Shares covered by such Option shall revert to the
Plan.


                                       13




         8.       DEATH OF OPTIONEE. In the event of termination of
Optionee's Continuous Status as an Employee or Consultant as a result of the
death of Optionee, the Option may be exercised at any time within six (6)
months following the date of death (but in no event later than the date of
expiration of the term of this Option as set forth in Section 10 below), by
Optionee's estate or by a person who acquired the right to exercise the
Option by bequest or inheritance, but only to the extent the Optionee could
exercise the Option at the date of death.

         9.       NON-TRANSFERABILITY OF OPTION. This Option may not be
transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of Optionee only by
Optionee. The terms of this Option shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

         10.      TERM OF OPTION. This Option may be exercised only within
the term set out in the Notice of Grant, and may be exercised during such
term only in accordance with the Plan and the terms of this Option. The
limitations set out in Section 7 of the Plan regarding Options designated as
Incentive Stock Options and Options granted to more than ten percent (10%)
shareholders shall apply to this Option.

         11.      TAXATION UPON EXERCISE OF OPTION. Optionee understands
that, upon exercising a Nonstatutory Option, he or she will recognize income
for tax purposes in an amount equal to the excess of the then Fair Market
Value of the Shares over the exercise price. However, the timing of this
income recognition may be deferred for up to six months if Optionee is
subject to Section 16 of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"). If the Optionee is an Employee, the Company will be required
to withhold from Optionee's compensation, or collect from Optionee and pay to
the applicable taxing authorities an amount equal to a percentage of this
compensation income. Additionally, the Optionee may at some point be required
to satisfy tax withholding obligations with respect to the disqualifying
disposition of an Incentive Stock Option. The Optionee shall satisfy his or
her tax withholding obligation arising upon the exercise of this Option out
of Optionee's compensation or by payment to the Company.

         12.      TAX CONSEQUENCES. Set forth below is a brief summary as of
the date of this Option of some of the federal and state tax consequences of
exercise of this Option and disposition of the Shares. THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO
CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION
OR DISPOSING OF THE SHARES.

                 (i) EXERCISE OF ISO. If this Option qualifies as an ISO, there
will be no regular federal income tax liability or state income tax liability
upon the exercise of the Option, although the excess, if any, of the Fair Market
Value of the Shares on the date of exercise over the Exercise Price will be
treated as an adjustment to the alternative minimum tax for federal tax purposes
and may subject the Optionee to the alternative minimum tax in the year of
exercise.

                 (ii) EXERCISE OF ISO FOLLOWING DISABILITY. If the Optionee's
Continuous Status as an Employee or Consultant terminates as a result of
disability that is not total and permanent disability as defined in Section
22(e)(3) of the Code, to the extent permitted on the date of termination, the
Optionee must exercise an ISO within 90 days of such termination for the ISO to
be qualified as an ISO.


                                      14




                 (iii) EXERCISE OF NONSTATUTORY STOCK OPTION. There may be a
regular federal income tax liability and state income tax liability upon the
exercise of a Nonstatutory Stock Option. The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price. If Optionee is an Employee or a former Employee, the
Company will be required to withhold from Optionee's compensation or collect
from Optionee and pay to the applicable taxing authorities an amount in cash
equal to a percentage of this compensation income at the time of exercise, and
may refuse to honor the exercise and refuse to deliver Shares if such
withholding amounts are not delivered at the time of exercise.

                 (iv) DISPOSITION OF SHARES. In the case of an NSO, if Shares
are held for at least one year, any gain realized on disposition of the Shares
will be treated as long-term capital gain for federal and state income tax
purposes. In the case of an ISO, if Shares transferred pursuant to the Option
are held for at least one year after exercise and are disposed of at least two
years after the Date of Grant, any gain realized on disposition of the Shares
will also be treated as long-term capital gain for federal and state income tax
purposes. If Shares purchased under an ISO are disposed of within such one-year
period or within two years after the Date of Grant, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the difference between the Exercise Price and the lesser
of (1) the Fair Market Value of the Shares on the date of exercise, or (2) the
sale price of the Shares.

                 (v) NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES. If the
Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

         13. ENTIRE AGREEMENT; GOVERNING LAW. The Plan is incorporated herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee. This agreement is governed by California law except for that body of
law pertaining to conflict of laws.

IN THE COMPANY'S STOCK OPTION PLAN WHICH IS INCORPORATED HEREIN BY REFERENCE,

WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE OPTIONEE'S
EMPLOYMENT OR CONSULTANCY AT ANY TIME, WITH OR WITHOUT CAUSE.

any questions arising under the Plan or this Option. Optionee further agrees to
notify the Company upon any change in the residence address indicated below.

undersigned ("Optionee") hereby elects to exercise Optionee's option to purchase
_________ shares of the Common Stock (the "Shares") of cadMOS Design Technology,
Inc. (the "Company") under and pursuant to the 1997 Stock Option Plan, as
amended (the "Plan") and the [ ] Incentive [ ] Nonstatutory Stock Option
Agreement dated ________, 19__ (the "Option Agreement").

         2. REPRESENTATIONS OF OPTIONEE. Optionee acknowledges that Optionee has
received, read and understood the Plan and the Option Agreement and agrees to
abide by and be bound by their terms and conditions.

         3. RIGHTS AS SHAREHOLDER. Until the stock certificate evidencing such
Shares is issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a shareholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option. The
Company shall issue (or cause to be issued) such stock certificate promptly
after the Option is exercised. No adjustment will be made for a dividend or
other right for which the record date is prior to the date the stock certificate
is issued, except as provided in Section 11 of the Plan.

                 Optionee shall enjoy rights as a shareholder until such time as
Optionee disposes of the Shares or the Company and/or its assignee(s) exercises
the Right of First Refusal hereunder. Upon such exercise, Optionee shall have no
further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Optionee shall forthwith cause the certificate(s) evidencing
the Shares so purchased to be surrendered to the Company for transfer or
cancellation.

         4. COMPANY'S RIGHT OF FIRST REFUSAL. Before any Shares held by Optionee
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this Section (the
"Right of First Refusal").

                 (a) NOTICE OF PROPOSED TRANSFER. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee


                                       1



("Proposed Transferee"); (iii) the number of Shares to be transferred to each
Proposed Transferee; and (iv) the bona fide cash price or other consideration
for which the Holder proposes to transfer the Shares (the "Offered Price"),
and the Holder shall offer the Shares at the Offered Price to the Company or
its assignee(s).

                 (b) EXERCISE OF RIGHT OF FIRST REFUSAL. At any time within
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

                 (c) PURCHASE PRICE. The purchase price ("Purchase Price") for
the Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

                 (d) PAYMENT. Payment of the Purchase Price shall be made, at
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

                 (e) HOLDER'S RIGHT TO TRANSFER. If all of the Shares proposed
in the Notice to be transferred to a given Proposed Transferee are not purchased
by the Company and/or its assignee(s) as provided in this Section, then the
Holder may sell or otherwise transfer such Shares to that Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 120 days after the date of the Notice and
provided further that any such sale or other transfer is effected in accordance
with any applicable securities laws and the Proposed Transferee agrees in
writing that the provisions of this Section shall continue to apply to the
Shares in the hands of such Proposed Transferee. If the Shares described in the
Notice are not transferred to the Proposed Transferee within such period, a new
Notice shall be given to the Company, and the Company and/or its assignees shall
again be offered the Right of First Refusal before any Shares held by the Holder
may be sold or otherwise transferred.

                 (f) EXCEPTION FOR CERTAIN FAMILY TRANSFERS. Anything to the
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Optionee's lifetime or on the Optionee's death by will
or intestacy to the Optionee's immediate family or a trust for the benefit of
the Optionee's immediate family shall be exempt from the provisions of this
Section. "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

                 (g) TERMINATION OF RIGHT OF FIRST REFUSAL. The Right of First
Refusal shall terminate as to any Shares 90 days after the first sale of Common
Stock of the Company to the


                                       -2-

of 1933, as amended.

         5. TAX CONSULTATION. Optionee understands that Optionee may suffer
adverse tax consequences as a result of Optionee's purchase or disposition of
the Shares. Optionee represents that Optionee has consulted with any tax
consultants Optionee deems advisable in connection with the purchase or
disposition of the Shares and that Optionee is not relying on the Company for
any tax advice.

         6.      RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

                 (a) LEGENDS. Optionee understands and agrees that the Company
shall cause the legends set forth below or legends substantially equivalent
thereto, to be placed upon any certificate(s) evidencing ownership of the Shares
together with any other legends that may be required by the Company or by state
or federal securities laws:

                 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                 UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE
                 OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED
                 UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF
                 COUNSEL TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR
                 TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

                 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                 CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL
                 HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE
                 EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF
                 THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL
                 OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF
                 FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES.

                 IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS
                 SECURITY, OR ANY INTEREST THEREIN, OR TO RECEIVE ANY
                 CONSIDERATION THEREFOR, WITHOUT THE PRIOR WRITTEN CONSENT OF
                 THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA,
                 EXCEPT AS PERMITTED IN THE COMMISSIONER'S RULES.

                 THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO RESTRICTIONS
                 ON TRANSFER FOR A PERIOD OF 180 DAYS FOLLOWING THE EFFECTIVE
                 DATE OF THE COMPANY'S


                                       -3-



                 INITIAL UNDERWRITTEN PUBLIC OFFERING AND MAY NOT BE SOLD OR
                 OTHERWISE DISPOSED OF BY THE HOLDER WITHOUT THE CONSENT OF THE
                 COMPANY OR THE MANAGING UNDERWRITER."

                 Optionee understands that transfer of the Shares may be
restricted by Section 260.141.11 of the Rules of the California Corporations
Commissioner, a copy of which is attached to Exhibit B, the Investment
Representation Statement.

                 (b) STOP-TRANSFER NOTICES. Optionee agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

                 (c) REFUSAL TO TRANSFER. The Company shall not be required (i)
to transfer on its books any Shares that have been sold or otherwise transferred
in violation of any of the provisions of this Agreement or (ii) to treat as
owner of such Shares or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares shall have been so
transferred.

         7. MARKET STANDOFF. Optionee hereby agrees that if so requested by the
Company or any representative of the underwriters in connection with any
registration of the offering of the securities of the Company under the
Securities Act of 1933, as amended (the "Act"), Optionee shall not sell or
otherwise transfer the Shares for a period of 180 days following the effective
date of a Registration filed under the Act; provided, that such restriction
shall apply only to the first registration statement of the Company to become
effective under the Act which include securities to be sold on behalf of the
Company in an underwritten offering under the Act. The Company may impose
stop-transfer instructions with respect to the Shares subject to the foregoing
restrictions until the end of each such 180-day period.

         8. SUCCESSORS AND ASSIGNS. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Optionee and his or her heirs, executors, administrators, successors and
assigns.

         9. INTERPRETATION. Any dispute regarding the interpretation of this
Agreement shall be submitted by Optionee or by the Company forthwith to the
Company's Board of Directors or the committee thereof that administers the Plan,
which shall review such dispute at its next regular meeting. The resolution of
such a dispute by the Board or committee shall be final and binding on the
Company and on Optionee.

         10. GOVERNING LAW; SEVERABILITY. This Agreement shall be governed by
and construed in accordance with the laws of the State of California excluding
that body of law pertaining to conflicts of law. Should any provision of this
Agreement be determined by a court of law to be illegal or unenforceable, the
other provisions shall nevertheless remain effective and shall remain
enforceable.

                       INVESTMENT REPRESENTATION STATEMENT

OPTIONEE         :

COMPANY          :       CADMOS DESIGN TECHNOLOGY, INC.

SECURITY         :       COMMON STOCK

AMOUNT           :

DATE       :


In connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following:

                 (a) Optionee is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Securities. Optionee
is acquiring these Securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

                 (b) Optionee acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Optionee's investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be unavailable if
Optionee's representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one year or any other fixed
period in the future. Optionee further understands that the Securities must be
held indefinitely unless they are subsequently registered under the Securities
Act or an exemption from such registration is available. Optionee further
acknowledges and understands that the Company is under no obligation to register
the Securities. Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company, a legend prohibiting their
transfer without the consent of the Commissioner of Corporations of the State of
California and any other legend required under applicable state securities laws.

                 (c) Optionee is familiar with the provisions of Rule 701 and
Rule 144, each promulgated under the Securities Act, which, in substance, permit
limited public resale of "restricted securities" acquired, directly or
indirectly from the issuer thereof, in a non-public offering subject to the
satisfaction of certain conditions. Rule 701 provides that if the issuer
qualifies under Rule 701 at


                                       -1-



the time of the grant of the Option to the Optionee, the exercise will be
exempt from registration under the Securities Act. In the event the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144, including: (1) the resale being made
through a broker in an unsolicited "broker's transaction" or in transactions
directly with a market maker (as said term is defined under the Securities
Exchange Act of 1934); and, in the case of an affiliate, (2) the availability
of certain public information about the Company, (3) the amount of Securities
being sold during any three month period not exceeding the limitations
specified in Rule 144(e), and (4) the timely filing of a Form 144, if
applicable.

         In the event that the Company does not qualify under Rule 701 at the
time of grant of the Option, then the Securities may be resold in certain
limited circumstances subject to the provisions of Rule 144, which requires the
resale to occur not less than two years after the later of the date the
Securities were sold by the Company or the date the Securities were sold by an
affiliate of the Company, within the meaning of Rule 144; and, in the case of
acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than three years, the satisfaction of the
conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

                 (d) Optionee hereby agrees that if so requested by the Company
or any representative of the underwriters in connection with any registration of
the offering of any securities of the Company under the Securities Act, Optionee
shall not sell or otherwise transfer any Shares or other securities of the
Company during the 180-day period following the effective date of a registration
statement of the Company filed under the Securities Act; provided, however, that
such restriction shall only apply to the first registration statement of the
Company to become effective under the Securities Act which include securities to
be sold on behalf of the Company to the public in an underwritten public
offering under the Securities Act. The Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such 180-day period.

                 (e) Optionee further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Optionee understands that no assurances can be given that any
such other registration exemption will be available in such event.

                 (f) Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities without the consent of the Commissioner of Corporations of
California. Optionee has read the applicable Commissioner's Rules with respect
to such


                                      -2-



restriction, a copy of which is attached.

                             Signature of Optionee:

              STATE OF CALIFORNIA - CALIFORNIA ADMINISTRATIVE CODE

         Title 10. Investment - Chapter 3. Commissioner of Corporations

      260.141.11: RESTRICTION ON TRANSFER. (a) The issuer of any security upon

260.141.10 or 260.534 shall cause a copy of this section to be delivered to each
issuee or transferee of such security at the time the certificate evidencing the
security is delivered to the issuee or transferee.

      (b) It is unlawful for the holder of any such security to consummate a
sale or transfer of such security, or any interest therein, without the prior
written consent of the Commissioner (until this condition is removed pursuant to
Section 260.141.12 of these rules), except:

           (1)  to the issuer;
           (2)  pursuant to the order or process of any court;
           (3) to any person described in Subdivision (i) of Section 25102 of

           (4) to the transferor's ancestors, descendants or spouse, or any
      custodian or trustee for the account of the transferor or the transferor's
      ancestors, descendants, or spouse; or to a transferee by a trustee or
      custodian for the account of the transferee or the transferee's ancestors,
      descendants or spouse;
           (5)  to holders of securities of the same class of the same issuer;
           (6)  by way of gift or donation inter vivos or on death;
           (7) by or through a broker-dealer licensed under the Code (either
      acting as such or as a finder) to a resident of a foreign state, territory
      or country who is neither domiciled in this state to the knowledge of the
      broker-dealer, nor actually present in this state if the sale of such
      securities is not in violation of any securities law of the foreign state,
      territory or country concerned;
           (8)  to a  broker-dealer  licensed  under the Code in a principal
      transaction, or as an underwriter or member of an underwriting syndicate
      or selling group;
           (9) if the interest sold or transferred is a pledge or other lien
      given by the purchaser to the seller upon a sale of the security for which
      the Commissioner's written consent is obtained or under this rule not
      required;
          (10) by way of a sale qualified under Sections 25111, 25112, 25113 or
      25121 of the Code, of the securities to be transferred, provided that no
      order under Section 25140 or subdivision (a) of Section 25143 is in effect
      with respect to such qualification;
          (11)  by a  corporation  to a  wholly  owned  subsidiary  of  such
      corporation, or by a wholly owned subsidiary of a corporation to such
      corporation;
          (12) by way of an exchange qualified under Section 25111, 25112 or
      25113 of the Code, provided that no order under Section 25140 or
      subdivision (a) of Section 25143 is in effect with respect to such
      qualification;
          (13)  between  residents of foreign  states,  territories  or
      countries who are neither domiciled nor actually present in this state;
          (14)  to the State  Controller  pursuant to the  Unclaimed  Property
      Law or to the administrator of the unclaimed property law of another
      state; or
          (15) by the State Controller pursuant to the Unclaimed Property Law or
      by the administrator of the unclaimed property law of another state if, in
      either such case, such person (i) discloses to potential purchasers at the
      sale that transfer of the securities is restricted under this rule, (ii)
      delivers to each purchaser a copy of this rule, and (iii) advises the
      Commissioner of the name of each purchaser;
          (16)  by a  trustee  to a  successor  trustee  when  such  transfer
      does not involve a change in the beneficial ownership of the securities;
          (17) by way of an offer and sale of outstanding securities in an
      issuer transaction that is subject to the qualification requirement of
      Section 25110 of the Code but exempt from that qualification requirement
      by subdivision (f) of Section 25102; provided that any such transfer is on
      the condition that any certificate evidencing the security issued to such
      transferee shall contain the legend required by this section.

      (c) The certificates representing all such securities subject to such a
restriction on transfer, whether upon initial issuance or upon any transfer
thereof, shall bear on their face a legend, prominently stamped or printed
thereon in capital letters of not less than 10-point size, reading as follows:



           "IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS SECURITY, OR
