                        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.

         (a)      "AFFILIATE" means any entity other than a Subsidiary, if
the Company and/or one or more Subsidiaries own not less than 50% of such
entity. For purposes of determining an individual's "Service," this
definition shall include any entity other than a Subsidiary, if the Company,
a Parent and/or one or more Subsidiaries own not less than 50% of such entity.

         (b)      "BOARD" means the Board of Directors of the Company, as
constituted from time to time.

         (c)      "CHANGE IN CONTROL" except as may otherwise be provided in
the Stock Option Agreement, means the occurrence of any of the following:

                  (i)      The consummation of a merger or consolidation of
         the Company with or into another entity or any other corporate
         reorganization, if more than 50% of the combined voting power of the
         continuing or surviving entity's securities outstanding immediately
         after such merger, consolidation or other reorganization is owned
         by persons who were not stockholders of the Company immediately
         prior to such merger, consolidation or other reorganization;

<PAGE>

                  (ii)     The sale, transfer or other disposition of all or
         substantially all of the Company's assets;

                  (iii)    Any transaction as a result of which any person
         becomes the "beneficial owner" (as defined in Rule 13d-3 under the
         Exchange Act), directly or indirectly, of securities of the Company
         representing at least 20% of the total voting power represented
         by the Company's then outstanding voting securities. For purposes
         of this Paragraph (iii), the term "person" shall have the same
         meaning as when used in sections 13(d) and 14(d) of the Exchange
         Act but shall exclude:

                           (A)      A trustee or other fiduciary holding
                  securities under an employee benefit plan of the Company

                           (B)      A corporation owned directly or
                  indirectly by the stockholders of the Company in
                  substantially the same proportions as their ownership
                  of the common stock of the Company; and

                           (C)      Any direct or indirect acquisition of the
                  Company's voting securities by Phoenix Technologies Ltd.

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.

                                      5
<PAGE>

         (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

                                      6
<PAGE>

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.

                                      7

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.

                                      8
<PAGE>

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
right to restrict, in whole or in part, the delivery of Shares pursuant to
any Option 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 11. WITHHOLDING TAXES.

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

                                      9
<PAGE>

         (b)      SHARE WITHHOLDING. If a public market for the Company's
Shares exists, the Committee may permit an Optionee 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 12. 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 Options made shall be null and void and no additional Grants 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 12(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 Option previously
granted under the Plan. No Options 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 13. 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.

                        EFFECTIVE AS OF [EFFECTIVE DATE]

SECTION 1. INTRODUCTION.

         The Company's Board of Directors adopted the inSilicon Corporation
         2000 Stock Plan on January 12, 2000 and the Company's stockholder
         approved the Plan on January 12, 2000. The Plan is effective on
         [EFFECTIVE DATE], 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

         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 or any Restricted Stock Agreement, and (ii)

         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

         own behalf. The foregoing right of indemnification shall not be

         (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.

                                      6
<PAGE>

                  (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

                                      7
<PAGE>

         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.

                                      8
<PAGE>

         (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

                                      9
<PAGE>

         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

                                      10
<PAGE>

         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

                                      11
<PAGE>

         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.

                                      12

SECTION 14. EXECUTION.
