(1)      This Registration Statement shall also cover any additional shares of
         Registrant's Common Stock which become issuable under the inSilicon
         Corporation 1999 Stock Option Plan and the inSilicon Corporation 2000
         Stock Plan by reason of any stock dividend, stock split,
         recapitalization or other similar transaction effected without the
         Registrant's receipt of consideration which results in an increase in
         the number of the Registrant's outstanding shares of Common Stock.

(2)      Calculated solely for purposes of this offering under Rule 457(h) of
         the Securities Act of 1933, as amended (the "1933 Act"), on the basis
         of the weighted average exercise price of the outstanding options.

(3)      The Registrant filed a registration statement on Form S-4 (Registration
         No. 333-75638) on December 21, 2001 (the "Form S-4"), to register
         certain shares of its common stock in connection with the transaction
         described therein. The filing fee remitted for the S-4 was $209,040.53.
         Subsequently, the Commission issued Fee Rate Advisory No. 8 on January
         16, 2002, which retroactively reduced Securities Act filing fees. As a
         result, the Registrant now has a credit of $128,573 with the
         Commission, as reduced by the fees for subsequent filings. The
         registration fee for this registration statement is being offset
         against such credit.

Item 6.  Indemnification of Directors and Officers

         Section 145 of the Delaware General Corporation Law permits a
corporation to include in its charter documents, and in agreements between the
corporation and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

provides for the indemnification of directors to the fullest extent permissible
under Delaware Law.

         Article VII of the Registrant's Bylaws provides for the indemnification
of officers, directors and third parties to the fullest extent permissible under
Delaware Law, which provisions are deemed to be a contract between the
Registrant and each director and officer who serves in such capacity while such
bylaw is in effect.

         The Registrant has entered into indemnification agreements with its
directors and executive officers, in addition to the indemnification provided
for in the Registrant's Bylaws, and intends to enter into indemnification
agreements with any new directors and executive officers in the future. The
Registrant has also obtained liability insurance for the benefit of its
directors and officers.

--------------------------------------------------------------------------------
     * incorporated herein by reference pursuant
     to Items 3(d) and 3(e) of this Registration Statement.

Item 9. Undertakings

         A. 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, as amended (the "1933 Act"),
(ii) to reflect in the prospectus any facts or events arising after the
effective date of this 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
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 clauses (1)(i) and (1)(ii) shall not apply if the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the Registrant pursuant to Section 13 or
Section 15(d) of the 1934 Act that are incorporated by reference into this
Registration Statement; (2) that for the purpose of determining any liability
under the 1933 Act each such post-effective amendment 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; and (3) to remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold at the termination of the offering.

                                      II-3


         B. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is
incorporated by reference into 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.

         C. Insofar as indemnification for liabilities arising under the 1933
Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnification provisions summarized in Item 6 or
otherwise, the Registrant has been advised that, in the opinion of the
Commission, such indemnification is against public policy as expressed in the
1933 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 the 1933 Act and
will be governed by the final adjudication of such issue.

         Re: Synopsys, Inc. - Registration Statement on Form S-8

Ladies and Gentlemen:

         We have acted as counsel to Synopsys, Inc., a Delaware corporation (the
"Company"), in connection with the registration on Form S-8 (the "Registration
Statement") under the Securities Act of 1933, as amended, of 169,940 shares of
its common stock (the "Shares") issuable upon exercise of stock options granted
under the inSilicon Corporation 1999 Stock Option Plan and the inSilicon
Corporation 2000 Stock Plan (collectively, the "inSilicon Plans"), which have
been assumed by the Company.

         We have reviewed the Company's charter documents and the corporate
proceedings taken by the Company in connection with the assumption of the
inSilicon Plans and the options outstanding thereunder. Based on such review, we
are of the opinion that if, as and when the Shares are issued and sold (and the
consideration therefor received) pursuant to the provisions of option agreements
duly authorized under the inSilicon Plans and in accordance with the
Registration Statement, such Shares will be legally issued, fully paid and
nonassessable.

         We consent to the filing of this opinion letter as an Exhibit to the
Registration Statement.

                                                     Very truly yours,
                                          Wilson Sonsini Goodrich & Rosati, P.C.

                         EFFECTIVE AS OF DECEMBER 21, 1999

SECTION 1.........INTRODUCTION.

         The Company's Board of Directors adopted the inSilicon Corporation 1999
Stock Option Plan on December 21, 1999, subject to approval by the Company's
stockholders.

         The purpose of the Plan is to promote the long-term success of the
Company and the creation of shareholder value by offering Key Employees an
opportunity to acquire a proprietary interest in the success of the Company, or
to increase such interest, and to encourage such selected persons to continue to
provide services to the Company and to attract new individuals with outstanding
qualifications.

         The Plan seeks to achieve this purpose by providing for Options (which
may constitute Incentive Stock Options or Nonstatutory Stock Options).

         The Plan shall be governed by, and construed in accordance with, the
laws of the State of California (except its choice-of-law provisions).
Capitalized terms shall have the meaning provided in Section 2 unless otherwise
provided in this Plan or Stock Option Agreement.
SECTION 2.........DEFINITIONS.

Subsidiaries own not less than 50% of such entity.

20% of the total voting power represented by the Company's then outstanding
voting securities. For purposes of this Paragraph

securities by Phoenix Technologies Ltd.

        SECTION 3.........ADMINISTRATION.

        (a) COMMITTEE COMPOSITION. A Committee appointed by the Board shall
administer the Plan. The Board shall designate one of the members of the
Committee as chairperson. If no Committee has been approved, the entire Board
shall constitute the Committee. Members of the Committee shall serve for such
period of time as the Board may determine and shall be subject to removal by the
Board at any time. The Board may also at any time terminate the functions of the
Committee and reassume all powers and authority previously delegated to the
Committee.

         Effective with the Company's initial public offering, the Committee
shall consist either (i) of those individuals who shall satisfy the requirements
of Rule 16b-3 (or its successor) under the Exchange Act with respect to Options
to persons who are officers or directors of the Company under Section 16 of the

(i) any loss, cost, liability, or expense that may be imposed upon or reasonably
incurred by him or her in connection with or resulting from any claim, action,
suit, or proceeding to which he or she may be a party or in which he or she may
be involved by reason of any action taken or failure to act under the Plan or
any Stock Option Agreement, and (ii) from any and all amounts paid by him or her
in settlement thereof, with the Company's approval, or paid by him or her in
satisfaction of any judgment in any such claim, action, suit, or proceeding
against him or her, provided he or she shall give the Company an opportunity, at
its own expense, to handle and defend the same before he or she undertakes to
handle and defend it on his or her own behalf. The foregoing right of
indemnification shall not be exclusive of any other rights of indemnification to
which such persons may be entitled under the Company's Certificate of
Incorporation or Bylaws, by contract, as a matter of law, or otherwise, or under
any power that the Company may have to indemnify them or hold them harmless.

                (d) FINANCIAL REPORTS. To the extent required by applicable law,
the Company shall furnish to Optionees the Company's summary financial
information including a balance sheet regarding the Company's financial
condition and results of operations, unless such Optionees have duties with the
Company that assure them access to equivalent information. Such financial
statements need not be audited.

        SECTION 4.........ELIGIBILITY.

                (a) GENERAL RULES.  Only Employees, Directors, Non-Employee
Directors and Consultants shall be eligible for designation as Key Employees by
the Committee.

                (b) INCENTIVE STOCK OPTIONS. Only Key Employees who are common-
law employees of the Company, a Parent or a Subsidiary shall be eligible for the
grant of ISOs. In addition, a Key Employee who is a 10-Percent Shareholder shall
not be eligible for the grant of an ISO unless the requirements set forth in
section 422(c)(5) of the Code are satisfied.

        SECTION 5.........SHARES SUBJECT TO PLAN.

                (a) BASIC LIMITATION. The stock issuable under the Plan shall be
authorized but unissued Shares or treasury Shares. The aggregate number of
Shares reserved for Grants under the Plan shall not exceed 2,700,000 Shares on a
fully diluted basis, subject to adjustment pursuant to Section 8.

                (b) ADDITIONAL SHARES. If Options are forfeited or terminate for
any other reason before being exercised, then such Options shall again become
available for Grants under the Plan.

                (c) DIVIDEND EQUIVALENTS.  Any dividend equivalents distributed
under the Plan shall not be applied against the number of Options available for
Grants.

        SECTION 6.........TERMS AND CONDITIONS OF OPTIONS.

                (a) STOCK OPTION AGREEMENT. Each Grant under the Plan shall be
evidenced by a Stock Option Agreement between the Optionee and the Company. Such
Option shall be subject to all applicable terms and conditions of the Plan and
may be subject to any other terms and conditions that are not inconsistent with
the Plan and that the Committee deems appropriate for inclusion in a Stock
Option Agreement. The provisions of the various Stock Option Agreements entered
into under the Plan need not be identical. A Stock Option Agreement may provide
that new Options will be granted automatically to the Optionee when he or she
exercises the prior Options. The Stock Option Agreement shall also specify
whether the Option is an ISO or an NSO.

                (b) NUMBER OF SHARES. Each Stock Option Agreement shall specify
the number of Shares that are subject to the Option and shall provide for the
adjustment of such number in accordance with Section 8.

                (c) EXERCISE PRICE. An Option's Exercise Price shall be
established by the Committee and set forth in a Stock Option Agreement. To the
extent required by applicable law the Exercise Price of an ISO shall not be less
than 100% of the Fair Market Value (110% for 10-Percent Shareholders) of a Share
on the date of Grant. In the case of an NSO, a Stock Option Agreement may
specify an Exercise Price that varies in accordance with a predetermined formula
while the NSO is outstanding. To the extent required by applicable law, the
Exercise Price for an NSO shall not be less than 85% of the Fair Market Value
(110% for 10-Percent Shareholders) of a Share on the date of Grant.

                (d) EXERCISABILITY AND TERM. Each Stock Option Agreement shall
specify the date when all or any installment of the Option is to become
exercisable. To the extent required by applicable law, Options shall vest at
least as rapidly as 20% annually over a five-year period. The Stock Option
Agreement shall also specify the term of the Option; provided that the term of
an ISO, and to the extent required by applicable law a NSO, shall in no event
exceed ten (10) years from the date of Grant. An ISO that is granted to a
10-Percent Shareholder shall have a maximum term of five (5) years. To the
extent required by applicable law, vested Options shall be exercisable for a
minimum period of six (6) months following termination of employment due to
death or Disability and thirty (30) days following any other termination of
employment (other than terminations for cause, as defined in the Company's
personnel policies). Notwithstanding the previous sentence, no Option can be
exercised after the expiration date provided in the applicable Stock Option
Agreement. A Stock Option Agreement may provide for accelerated exercisability
in the event of the Optionee's death, disability or retirement or other events
and may provide for expiration prior to the end of its term in the event of the
termination of the Optionee's service. A Stock Option Agreement may permit an
Optionee to exercise an Option before it is vested, subject to the Company's
right of repurchase over any Shares acquired under the unvested portion of the
Option (an "early exercise"), which right of repurchase shall lapse at the same
rate the Option would have vested had there been no early exercise. In no event
shall the Company be required to issue fractional Shares upon the exercise of an
Option.

                (e) MODIFICATIONS OR ASSUMPTION OF OPTIONS. Within the
limitations of the Plan, the Committee may modify, extend or assume outstanding
options or may accept the cancellation of outstanding options (whether granted
by the Company or by another issuer) in return for the grant of new Options for
the same or a different number of Shares and at the same or a different Exercise
Price. The foregoing notwithstanding, no modification of an Option shall,
without the consent of the Optionee, alter or impair his or her rights or
obligations under such Option.

                (f) TRANSFERABILITY OF OPTIONS. Except as otherwise provided in
the applicable Stock Option Agreement and then only to the extent permitted by
applicable law, no Option shall be transferable by the Optionee other than by
will or by the laws of descent and distribution. Except as otherwise provided in
the applicable Stock Option Agreement, an Option may be exercised during the
lifetime of the Optionee only or by the guardian or legal representative of the
Optionee. No Option or interest therein may be assigned, pledged or hypothecated
by the Optionee during his lifetime, whether by operation of law or otherwise,
or be made subject to execution, attachment or similar process. 
                (g) NO RIGHTS AS A STOCKHOLDER. An Optionee, or a transferee of
an Optionee, shall have no rights as a stockholder with respect to any Common
Stock covered by an Option until such person becomes entitled to receive such
Common Stock by filing a notice of exercise and paying the Exercise Price
pursuant to the terms of such Option.

                (h) RESTRICTIONS ON TRANSFER. Any Shares issued upon exercise of
an Option shall be subject to such rights of repurchase, rights of first refusal
and other transfer restrictions as the Committee may determine. Such
restrictions shall apply in addition to any restrictions that may apply to
holders of Shares generally and shall also comply to the extent necessary with
applicable law.

        SECTION 7.........PAYMENT FOR OPTION SHARES.

                (a) GENERAL RULE. The entire Exercise Price of Shares issued
upon exercise of Options shall be payable in cash at the time when such Shares
are purchased, except as follows:
                        (i) In the case of an ISO granted under the Plan,
payment shall be made only pursuant to the express provisions of the applicable
Stock Option Agreement. The Stock Option Agreement may specify that payment may
be made in any form(s) described in this Section 7.

                        (ii) In the case of an NSO granted under the Plan, the
Committee may in its discretion, at any time accept payment in any form(s)
described in this Section 7.
                (b) SURRENDER OF STOCK. To the extent that this Section 7(b) is
applicable, payment for all or any part of the Exercise Price may be made with
Shares which have already been owned by the Optionee for such duration as shall
be specified by the Committee. Such Shares shall be valued at their Fair Market
Value on the date when the new Shares are purchased under the Plan.

                (c) PROMISSORY NOTE.  To the extent that this Section 7(c) is
applicable, payment for all or any part of the Exercise Price may be made with
a full-recourse promissory note.

                (d) OTHER FORMS OF PAYMENT. To the extent that this Section 7(d)
is applicable, payment may be made in any other form that is consistent with
applicable laws, regulations and rules.

        SECTION 8.........PROTECTION AGAINST DILUTION.

                (a) ADJUSTMENTS. In the event of a subdivision of the
outstanding Shares, a declaration of a dividend payable in Shares, a declaration
of a dividend payable in a form other than Shares in an amount that has a
material effect on the price of Shares, a combination or consolidation of the
outstanding Shares (by reclassification or otherwise) into a lesser number of
Shares, a recapitalization, a spin-off or a similar occurrence, the Committee
shall make such adjustments as it, in its sole discretion, deems appropriate in
one or more of:

                        (i) the number of Options available for future Grants
under Section 5;
                        (ii) the number of Shares covered by each outstanding
Option; or

                        (iii) the Exercise Price under each outstanding Option.

                (b) OPTIONEE RIGHTS. Except as provided in this Section 8, an
Optionee shall have no rights by reason of any issue by the Company of stock of
any class or securities convertible into stock of any class, any subdivision or
consolidation of shares of stock of any class, the payment of any stock dividend
or any other increase or decrease in the number of shares of stock of any class.

        SECTION 9.........EFFECT OF A CHANGE IN CONTROL.

                (a) MERGER OR REORGANIZATION. In the event that the Company is a
party to a merger or other reorganization, outstanding Options shall be subject
to the agreement of merger or reorganization. Such agreement may provide,
without limitation, for the assumption of outstanding Options by the surviving
corporation or its parent, for their continuation by the Company (if the Company
is a surviving corporation), for accelerated vesting or for their cancellation
with or without consideration, in all cases without the consent of the Optionee.

                (b) ACCELERATION. Except as otherwise provided in the applicable
Stock Option Agreement, in the event that a Change in Control occurs with
respect to the Company and the applicable agreement of merger or reorganization
provides for assumption or continuation of Options pursuant to Section 9(a) or
Options will otherwise continue, no acceleration of vesting shall occur. In the
event that a Change in Control occurs with respect to the Company and there is
no assumption or continuation of Options, all Options shall vest and become
immediately exercisable.

        SECTION 10........LIMITATIONS ON RIGHTS.

                (a) RETENTION RIGHTS. Neither the Plan nor any Option granted
under the Plan shall be deemed to give any individual a right to remain an
employee, consultant or director of the Company, a Parent, a Subsidiary or an
Affiliate. The Company and its Parents and Subsidiaries and Affiliates reserve
the right to terminate the Service of any person at any time, and for any
reason, subject to applicable laws, the Company's Certificate of Incorporation
and Bylaws and a written employment agreement (if any).

                (b) STOCKHOLDERS' RIGHTS. An Optionee shall have no dividend
rights, voting rights or other rights as a stockholder with respect to any
Shares covered by his or her Option prior to the issuance of a stock certificate
for such Shares. No adjustment shall be made for cash dividends or other rights
for which the record date is prior to the date when such certificate is issued,
except as expressly provided in Section 8.

                (c) REGULATORY REQUIREMENTS. Any other provision of the Plan
notwithstanding, the obligation of the Company to issue Shares under the Plan

shall be subject to all applicable laws, rules and regulations and such
approval by any regulatory body as may be required. The Company reserves the

SECTION 1.        INTRODUCTION.


         The Company's Board of Directors adopted the inSilicon Corporation 2000
Stock Plan on January 18, 2000 and the Company's stockholder approved the Plan
on January 18, 2000. The Plan is effective on the date of the Company's initial
public offering.

         The purpose of the Plan is to promote the long-term success of the
Company and the creation of shareholder value by offering Key Employees an
opportunity to acquire a proprietary interest in the success of the Company, or
to increase such interest, and to encourage such selected persons to continue to
provide services to the Company and to attract new individuals with outstanding
qualifications.

         The Plan seeks to achieve this purpose by providing for Options (which
may constitute Incentive Stock Options or Nonstatutory Stock Options) and Awards
of Restricted Stock.

         The Plan shall be governed by, and construed in accordance with, the
laws of the State of California (except its choice-of-law provisions).

and all amounts paid by him or her in settlement thereof, with the Company's
approval, or paid by him or her in satisfaction of any judgment in any such
claim, action, suit, or proceeding against him or her, provided he or she shall

other rights of indemnification to which such persons may be entitled under the
Company's Certificate of Incorporation or Bylaws, by contract, as a matter of

SECTION 4. ELIGIBILITY.

        (a) GENERAL RULES. Only Employees, Directors, Non-Employee Directors and
Consultants shall be eligible for designation as Key Employees by the Committee.

        (b) INCENTIVE STOCK OPTIONS. Only Key Employees who are common-law
employees of the Company, a Parent or a Subsidiary shall be eligible for the
grant of ISOs. In addition, a Key Employee who is a 10-Percent Shareholder shall
 not be eligible for the grant of an ISO unless the requirements set forth in
section 422(c)(5) of the Code are satisfied.

        (c) NON-EMPLOYEE DIRECTORS. Non-Employee Directors shall also be
eligible to receive Options as described in this Section 4(c) from and after the
date the Board has determined to implement this provision.

                (i) Each eligible Non-Employee Director shall automatically be
granted an NSO to purchase 20,000 Shares (subject to adjustment under Section 9)
as a result of his or her initial election or appointment as a Non-Employee
Director. Upon the conclusion of each regular annual meeting of the Company's
stockholders following his or her initial appointment, each eligible
Non-Employee Director who will continue serving as a member of the Board
thereafter shall receive an NSO to purchase 7,500 Shares (subject to adjustment
under Section 9). In addition, upon his or her appointment to the Audit
Committee or Compensation Committee of the Board, each Non-Employee Director
will receive an NSO to purchase 5,000 Shares (subject to adjustment under
Section 9). All NSOs granted pursuant to this Section 4 shall vest and become
exercisable at the rate of six and twenty-five hundredths percent (6.25%) of the
Shares subject to the Options per quarter grant from the date of grant, provided
the Non-Employee Director is serving as a director of the Company as of the
vesting date.

                (ii) All NSOs granted to Non-Employee Directors under this
Section 4(c) shall become exercisable in full in the event of Change in Control
with respect to the Company while the Director is providing service.

                (iii) The Exercise Price under all NSOs granted to a Non-
Employee Director under this Section 4(c) shall be equal to one hundred percent
(100%) of the Fair Market Value of a Common Share on the date of grant, payable
in one of the forms described in Section 7.

                (iv) All NSOs granted to a Non-Employee Director under this
Section 4(c) shall terminate on the earlier of:

                        (1) The 10th anniversary of the date of grant; or

                        (2) The date ninety (90) days after the termination of
such Non-Employee Director's service for any reason.

SECTION 5. SHARES SUBJECT TO PLAN.

        (a) BASIC LIMITATION. The stock issuable under the Plan shall be
authorized but unissued Shares or treasury Shares. The aggregate number of
Shares reserved for Awards under the Plan shall not exceed 1,300,000 plus such
number of shares as shall be available for grant under the Company's 1999 Stock
Plan on the Effective Date of the Plan. The foregoing limit is subject to
adjustment pursuant to Section 9.

        (b) ANNUAL ADDITION. Beginning with the first fiscal year of the Company
beginning after the Effective Date, on the first day of each fiscal year, Shares
will be added to the Plan equal to the lesser of (i) 2,000,000 Shares, or (ii)
five percent (5%) of the outstanding shares in the last day of the prior fiscal
year.

        (c) ADDITIONAL SHARES. If Awards are forfeited or terminate for any
other reason before being exercised, then the Shares underlying such Awards
shall again become available for Awards under the Plan.

        (d) DIVIDEND EQUIVALENTS.  Any dividend equivalents distributed under
the Plan shall not be applied against the number of Shares available for Awards.

        (e) LIMITS ON OPTIONS. No Key Employee shall receive Options to purchase
Shares during any fiscal year covering in excess of 2,000,000 Shares; provided,
however, a newly hired Key Employee may receive Options to purchase up to
1,000,000 Shares during the fiscal year of his or her date of hire.

        (f) LIMITS ON RESTRICTED STOCK. No Key Employee shall receive Award(s)
of Restricted Stock during any fiscal year covering in excess of 200,000 Shares.

SECTION 6.  TERMS AND CONDITIONS OF OPTIONS.

        (a) STOCK OPTION AGREEMENT. Each Grant under the Plan shall be evidenced
by a Stock Option Agreement between the Optionee and the Company. Such Option
shall be subject to all applicable terms and conditions of the Plan and may be
subject to any other terms and conditions that are not inconsistent with the
Plan and that the Committee deems appropriate for inclusion in a Stock Option
Agreement. The provisions of the various Stock Option Agreements entered into
under the Plan need not be identical. A Stock Option Agreement may provide that
new Options will be granted automatically to the Optionee when he or she
exercises the prior Options. The Stock Option Agreement shall also specify
whether the Option is an ISO or an NSO.

        (b) NUMBER OF SHARES. Each Stock Option Agreement shall specify the
number of Shares that are subject to the Option and shall provide for the
adjustment of such number in accordance with Section 9.

        (c) EXERCISE PRICE. An Option's Exercise Price shall be established by
the Committee and set forth in a Stock Option Agreement. To the extent required
by applicable law the Exercise Price of an ISO shall not be less than 100% of
the Fair Market Value (110% for 10-Percent Shareholders) of a Share on the date
of Grant. In the case of an NSO, a Stock Option Agreement may specify an
Exercise Price that varies in accordance with a predetermined formula while the
NSO is outstanding.

        (d) EXERCISABILITY AND TERM. Each Stock Option Agreement shall specify
the date when all or any installment of the Option is to become exercisable. The
Stock Option Agreement shall also specify the term of the Option; provided that
the term of an ISO shall in no event exceed ten (10) years from the date of
Grant. An ISO that is granted to a 10-Percent Shareholder shall have a maximum
term of five (5) years. No Option can be exercised after the expiration date
provided in the applicable Stock Option Agreement. A Stock Option Agreement may
provide for accelerated exercisability in the event of the Optionee's death,
disability or retirement or other events and may provide for expiration prior to
the end of its term in the event of the termination of the Optionee's service. A
Stock Option Agreement may permit an Optionee to exercise an Option before it is
vested, subject to the Company's right of repurchase over any Shares acquired
under the unvested portion of the Option (an "early exercise"), which right of
repurchase shall lapse at the same rate the Option would have vested had there
been no early exercise. In no event shall the Company be required to issue
fractional Shares upon the exercise of an Option.

        (e) MODIFICATIONS OR ASSUMPTION OF OPTIONS. Within the limitations of
the Plan, the Committee may modify, extend or assume outstanding options or may
accept the cancellation of outstanding options (whether granted by the Company
or by another issuer) in return for the grant of new Options for the same or a
different number of Shares and at the same or a different Exercise Price. The
foregoing notwithstanding, no modification of an Option shall, without the
consent of the Optionee, alter or impair his or her rights or obligations under
such Option.

        (f) TRANSFERABILITY OF OPTIONS. Except as otherwise provided in the
applicable Stock Option Agreement and then only to the extent permitted by
applicable law, no Option shall be transferable by the Optionee other than by
will or by the laws of descent and distribution. Except as otherwise provided in
the applicable Stock Option Agreement, an Option may be exercised during the
lifetime of the Optionee only or by the guardian or legal representative of the
Optionee. No Option or interest therein may be assigned, pledged or hypothecated
by the Optionee during his lifetime, whether by operation of law or otherwise,
or be made subject to execution, attachment or similar process.

        (g) NO RIGHTS AS STOCKHOLDER. An Optionee, or a transferee of an
Optionee, shall have no rights as a stockholder with respect to any Common Stock
covered by an Option until such person becomes entitled to receive such Common
Stock by filing a notice of exercise and paying the Exercise Price pursuant to
the terms of such Option.

        (h) RESTRICTIONS ON TRANSFER. Any Shares issued upon exercise of an
Option shall be subject to such rights of repurchase, rights of first refusal
and other transfer restrictions as the Committee may determine. Such 
restrictions shall apply in addition to any restrictions that may apply to
holders of Shares generally and shall also comply to the extent necessary with
applicable law.

SECTION 7.  PAYMENT FOR OPTION SHARES.

        (a) GENERAL RULE. The entire Exercise Price of Shares issued upon
exercise of Options shall be payable in cash at the time when such Shares are
purchased, except as follows:

                (i) In the case of an ISO granted under the Plan, payment shall
be made only pursuant to the express provisions of the applicable Stock Option
Agreement. The Stock Option Agreement may specify that payment may be made in
any form(s) described in this Section 7.

                (ii) In the case of an NSO granted under the Plan, the Committee
may in its discretion, at any time accept payment in any form(s) described in
this Section 7.

        (b) SURRENDER OF STOCK. To the extent that this Section 7(b) is
applicable, payment for all or any part of the Exercise Price may be made with
Shares which have already been owned by the Optionee for such duration as shall
be specified by the Committee. Such Shares shall be valued at their Fair Market
Value on the date when the new Shares are purchased under the Plan.

        (c) PROMISSORY NOTE.  To the extent that this Section 7(c) is
applicable, payment for all or any part of the

Exercise Price may be made with a full-recourse promissory note.

        (d) OTHER FORMS OF PAYMENT. To the extent that this Section 7(d) is
applicable, payment may be made in any other form that is consistent with
applicable laws, regulations and rules.

SECTION 8.  TERMS AND CONDITIONS FOR AWARDS OF RESTRICTED STOCK.

        (a) TIME, AMOUNT AND FORM OF AWARDS.  Awards under the Plan may be
granted in the form of Restricted Stock.

        (b) RESTRICTED STOCK AGREEMENT. Each Award of Restricted Stock under the
Plan shall be evidenced by a Restricted Stock Agreement between the Participant
and the Company. Such Award shall be subject to all applicable terms and
conditions of the Plan and may be subject to any other terms and conditions that
are not inconsistent with the Plan and that the Committee deems appropriate for
inclusion in a Restricted Stock Agreement. The provisions of the various
Restricted Stock Agreements entered into under the Plan need not be identical.
        (c) PAYMENT FOR RESTRICTED STOCK.  Restricted Stock may be issued with
or without cash consideration under the Plan.

        (d) VESTING CONDITIONS. Each Award of Restricted Stock shall become
vested, in full or in installments, upon satisfaction of the conditions

specified in the Restricted Stock Agreement. A Restricted Stock Agreement may
provide for accelerated vesting in the event of the Participant's death,
Disability or retirement or other events.

        (e) ASSIGNMENT OR TRANSFER OF RESTRICTED STOCK. Except as provided in
Section 12, or in a Restricted Stock Agreement, or as required by applicable
law, a Restricted Stock granted under the Plan shall not be anticipated,
assigned, attached, garnished, optioned, transferred or made subject to any
creditor's process, whether voluntarily, involuntarily or by operation of law.
Any act in violation of this Section 8(e) shall be void. However, this Section
8(e) shall not preclude a Participant from designating a beneficiary who will
receive any outstanding Restricted Stocks in the event of the Participant's
death, nor shall it preclude a transfer of Restricted Stocks by will or by the
laws of descent and distribution.

        (f) TRUSTS. Neither this Section 8 nor any other provision of the Plan
shall preclude a Participant from transferring or assigning Restricted Stock to
(a) the trustee of a trust that is revocable by such Participant alone, both at
the time of the transfer or assignment and at all times thereafter prior to such
Participant's death, or (b) the trustee of any other trust to the extent
approved in advance by the Committee in writing. A transfer or assignment of
Restricted Stock from such trustee to any person other than such Participant
shall be permitted only to the extent approved in advance by the Committee in
writing, and Restricted Stock held by such trustee shall be subject to all of
the conditions and restrictions set forth in the Plan and in the applicable
Restricted Stock Agreement, as if such trustee were a party to such Agreement.

        (g) VOTING AND DIVIDEND RIGHTS. The holders of Restricted Stock awarded
under the Plan shall have the same voting, dividend and other rights as the
Company's other stockholders. A Restricted Stock Agreement, however, may require
that the holders of Restricted Stock invest any cash dividends received in
additional Restricted Stock. Such additional Restricted Stock shall be subject
to the same conditions and restrictions as the Award with respect to which the
dividends were paid. Such additional Restricted Stock shall not reduce the
number of Shares available under Section 5.

SECTION 9.  PROTECTION AGAINST DILUTION.

        (a) ADJUSTMENTS. In the event of a subdivision of the outstanding
Shares, a declaration of a dividend payable in Shares, a declaration of a
dividend payable in a form other than Shares in an amount that has a material
effect on the price of Shares, a combination or consolidation of the outstanding
Shares (by reclassification or otherwise) into a lesser number of Shares, a
recapitalization, a spin-off or a similar occurrence, the Committee shall make
such adjustments as it, in its sole discretion, deems appropriate in one or more
of:

                (i) the number of Shares available for future Awards and the
per-person Share limits under Section 5;

                (ii) the number of Shares covered by each outstanding Award;

                (iii) the Exercise Price under each outstanding Option; or

                (iv) the number of Shares subject to Option grants under
Section 4(c).

        (b) PARTICIPANT RIGHTS. Except as provided in this Section 9, a
Participant shall have no rights by reason of any issue by the Company of stock
of any class or securities convertible into stock of any class, any subdivision
or consolidation of shares of stock of any class, the payment of any stock
dividend or any other increase or decrease in the number of shares of stock of
any class.

SECTION 10. EFFECT OF A CHANGE IN CONTROL.

        (a) MERGER OR REORGANIZATION. In the event that the Company is a party
to a merger or other reorganization, outstanding Awards shall be subject to the
agreement of merger or reorganization. Such agreement may provide, without
limitation, for the assumption of outstanding Awards by the surviving
corporation or its parent, for their continuation by the Company (if the Company
is a surviving corporation), for accelerated vesting or for their cancellation
with or without consideration, in all cases without the consent of the
Participant.

        (b) ACCELERATION. The Committee may determine, at the time of granting
an Award or thereafter, that such Award shall become fully vested as to all
Shares subject to such Award in the event that a Change in Control occurs with
respect to the Company.

SECTION 11. LIMITATIONS ON RIGHTS.

        (a) RETENTION RIGHTS. Neither the Plan nor any Award granted under the
Plan shall be deemed to give any individual a right to remain an employee,
consultant or director of the Company, a Parent, a Subsidiary or an Affiliate.
The Company and its Parents and Subsidiaries and Affiliates reserve the right to
terminate the Service of any person at any time, and for any reason, subject to
applicable laws, the Company's Certificate of Incorporation and Bylaws and a
written employment agreement (if any).

        (b) STOCKHOLDERS' RIGHTS. A Participant shall have no dividend rights,
voting rights or other rights as a stockholder with respect to any Shares
covered by his or her Award prior to the issuance of a stock certificate for
such Shares. No adjustment shall be made for cash dividends or other rights for
which the record date is prior to the date when such certificate is issued,
except as expressly provided in Section 9.

        (c) REGULATORY REQUIREMENTS. Any other provision of the Plan
notwithstanding, the obligation of the Company to issue Shares under the Plan
shall be subject to all applicable laws, rules and regulations and such approval
by any regulatory body as may be required. The Company reserves the right to
restrict, in whole or in part, the delivery of Shares pursuant to any Award
prior to the satisfaction of all legal requirements relating to the issuance of
such Shares, to their registration, qualification or listing or to an exemption
from registration, qualification or listing.

SECTION 12. WITHHOLDING TAXES.

        (a) GENERAL. A Participant shall make arrangements satisfactory to the
Company for the satisfaction of any withholding tax obligations that arise in
connection with his or her Award. The Company shall not be required to issue any
Shares or make any cash payment under the Plan until such obligations are
satisfied.

        (b) SHARE WITHHOLDING. If a public market for the Company's Shares
exists, the Committee may permit a Participant to satisfy all or part of his or
her withholding or income tax obligations by having the Company withhold all or
a portion of any Shares that otherwise would be issued to him or her or by
surrendering all or a portion of any Shares that he or she previously acquired.
Such Shares shall be valued at their Fair Market Value on the date when taxes
otherwise would be withheld in cash. Any payment of taxes by assigning Shares to
the Company may be subject to restrictions, including, but not limited to, any
restrictions required by rules of the Securities and Exchange Commission.

SECTION 13. DURATION AND AMENDMENTS.

        (a) TERM OF THE PLAN. The Plan, as set forth herein, shall become
effective on the date of its adoption by the Board, subject to the approval of
the Company's stockholders. No Options shall be exercisable until such
stockholder approval is obtained. In the event that the stockholders fail to
approve the Plan within twelve (12) months after its adoption by the Board, any
Awards made shall be null and void and no additional Awards shall be made. To
the extent required by applicable law, the Plan shall terminate on the date that
is ten (10) years after its adoption by the Board and may be terminated on any
earlier date pursuant to Section 13(b).

        (b) RIGHT TO AMEND OR TERMINATE THE PLAN. The Board may amend or
terminate the Plan at any time and for any reason. The termination of the Plan,
or any amendment thereof, shall not affect any Award previously granted under
the Plan. No Awards shall be granted under the Plan after the Plan's
termination. An amendment of the Plan shall be subject to the approval of the
Company's stockholders only to the extent required by applicable laws,
regulations or rules.

SECTION 14. EXECUTION.


        To record the adoption of the Plan by the Board, the Company has caused
its duly authorized officer to execute this Plan on behalf of the Company.
