                       INFORMATION STORAGE DEVICES, INC.

                           1994 EQUITY INCENTIVE PLAN

                         As Adopted September 12, 1994

                      As Amended through January 25, 1996

                1. PURPOSE. The purpose of the Plan is to provide incentives to
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent,
Subsidiaries and Affiliates, by offering them an opportunity to participate in
the Company's future performance through awards of Options, Restricted Stock and
Stock Bonuses. Capitalized terms not defined in the text are defined in Section
23.

                2.       SHARES SUBJECT TO THE PLAN.

                         2.1 Number of Shares Available. Subject to Sections 2.2
and 18, the total number of Shares reserved and available for grant and issuance
pursuant to the Plan shall be 2,000,000 Shares. Any shares issuable upon
exercise of options granted pursuant to the 1987 Stock Option Plan (the "Prior
Plan") that expire or become unexercisable for any reason without having been
exercised in full, shall no longer be available for distribution under the Prior
Plan, but shall be available for distribution under this Plan. Subject to
Sections 2.2 and 18, Shares shall again be available for grant and issuance in
connection with future Awards under the Plan that: (a) are subject to issuance
upon exercise of an Option but cease to be subject to such Option for any reason
other than exercise of such Option, (b) are subject to an Award granted
hereunder but are forfeited or are repurchased by the Company at the original
issue price, or (c) are subject to an Award that otherwise terminates without
Shares being issued.

                         2.2 Adjustment of Shares. In the event that the number
of outstanding Shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under the Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other outstanding Awards shall be
proportionately adjusted, subject to any required action by the Board or the
shareholders of the Company and compliance with applicable securities laws;
provided, however, that fractions of a Share shall not be issued but shall
either be paid in cash at Fair Market Value or shall be rounded up to the
nearest Share, as determined by the Committee.

                         3. ELIGIBILITY. ISOs (as defined in Section 5 below)
may be granted only to employees (including officers and directors who are also
employees) of the Company or of a Parent or Subsidiary of the Company. All other
Awards may be granted to employees, officers, directors, consultants,
independent contractors and advisors of the Company or any Parent, Subsidiary or
Affiliate of the Company; provided such consultants, contractors and advisors
render bona fide services not in connection with the offer and sale of
securities in a capital-raising transaction. No person shall be eligible to
receive more than 500,000 Shares at any time during the term of this Plan
pursuant to the grant of Awards hereunder. A person may be granted more than one
Award under the Plan.

                4.       ADMINISTRATION.

                         4.1 Committee Authority. The Plan shall be administered
by the Committee or the Board acting as the Committee. Subject to the general
purposes, terms and conditions of the Plan, and to the direction of the Board,
the Committee shall have full power to implement and carry out the Plan. The
Committee shall have the authority to:
   2
                (a) construe and interpret the Plan, any Award Agreement and any
                other agreement or document executed pursuant to the Plan;

                (b) prescribe, amend and rescind rules and regulations relating
                to the Plan;

                (c) select persons to receive Awards;

                (d) determine the form and terms of Awards;

                (e) determine the number of Shares or other consideration
                subject to Awards;

                (f) determine whether Awards will be granted singly, in
                combination, in tandem with, in replacement of, or as
                alternatives to, other Awards under the Plan or any other
                incentive or compensation plan of the Company or any Parent,
                Subsidiary or Affiliate of the Company;

                (g) grant waivers of Plan or Award conditions;

                (h) determine the vesting, exercisability and payment of Awards;

                (i) correct any defect, supply any omission, or reconcile any
                inconsistency in the Plan, any Award or any Award Agreement;

                (j) determine whether an Award has been earned; and

                (k) make all other determinations necessary or advisable for the
                administration of the Plan.

                         4.2 Committee Discretion. Any determination made by the
Committee with respect to any Award shall be made in its sole discretion at the
time of grant of the Award or, unless in contravention of any express term of
the Plan or Award, at any later time, and such determination shall be final and
binding on the Company and all persons having an interest in any Award under the
Plan. The Committee may delegate to one or more officers of the Company the
authority to grant an Award under the Plan to Participants who are not Insiders
of the Company.

                         4.3 Exchange Act Requirements. If two or more members
of the Board are Outside Directors, the Committee shall be comprised of at least
two members of the Board, all of whom are Outside Directors and Disinterested
Persons. The Company will take appropriate steps to comply with the
disinterested administration requirements of Section 16(b) of the Exchange Act,
which shall consist of the appointment by the Board of a Committee consisting of
not less than two members of the Board, each of whom is a Disinterested Person.

                         5. OPTIONS. The Committee may grant Options to eligible
persons and shall determine whether such Options shall be Incentive Stock
Options within the meaning of the Code ("ISOs") or Nonqualified Stock Options
("NQSOs"), the number of Shares subject to the Option, the Exercise Price of the
Option, the period during which the Option may be exercised, and all other terms
and conditions of the Option, subject to the following:

                                      -2-
   3
                         5.1 Form of Option Grant. Each Option granted under the
Plan shall be evidenced by an Award Agreement which shall expressly identify the
Option as an ISO or NQSO ("Stock Option Agreement"), and be in such form and
contain such provisions (which need not be the same for each Participant) as the
Committee shall from time to time approve, and which shall comply with and be
subject to the terms and conditions of the Plan.

                         5.2 Date of Grant. The date of grant of an Option shall
be the date on which the Committee makes the determination to grant such Option,
unless otherwise specified by the Committee. The Stock Option Agreement and a
copy of the Plan will be delivered to the Participant within a reasonable time
after the granting of the Option.

                         5.3 Exercise Period. Options shall be exercisable
within the times or upon the events determined by the Committee as set forth in
the Stock Option Agreement; provided, however, that no Option shall be
exercisable after the expiration of ten (10) years from the date the Option is
granted, and provided further that no ISO granted to a person who directly or by
attribution owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or any Parent or Subsidiary of the
Company ("Ten Percent Shareholder") shall be exercisable after the expiration of
five (5) years from the date the ISO is granted. The Committee also may provide
for the exercise of Options to become exercisable at one time or from time to
time, periodically or otherwise, in such number or percentage as the Committee
determines.

                         5.4 Exercise Price. The Exercise Price shall be
determined by the Committee when the Option is granted and may be not less than
85% of the Fair Market Value of the Shares on the date of grant; provided that
(i) the Exercise Price of an ISO shall be not less than 100% of the Fair Market
Value of the Shares on the date of grant and (ii) the Exercise Price of any ISO
granted to a Ten Percent Shareholder shall not be less than 110% of the Fair
Market Value of the Shares on the date of grant. Payment for the Shares
purchased may be made in accordance with Section 8 of the Plan.

                         5.5 Method of Exercise. Options may be exercised only
by delivery to the Company of a written stock option exercise agreement (the
"Exercise Agreement") in a form approved by the Committee (which need not be the
same for each Participant), stating the number of Shares being purchased, the
restrictions imposed on the Shares, if any, and such representations and
agreements regarding Participant's investment intent and access to information
and other matters, if any, as may be required or desirable by the Company to
comply with applicable securities laws, together with payment in full of the
Exercise Price for the number of Shares being purchased.

                         5.6 Termination. Notwithstanding the exercise periods
set forth in the Stock Option Agreement, exercise of an Option shall always be
subject to the following:

                (a)      If the Participant is Terminated for any reason except
                         death or Disability, then Participant may exercise such
                         Participant's Options only to the extent that such
                         Options would have been exercisable upon the
                         Termination Date no later than three (3) months after
                         the Termination Date (or such shorter time period as
                         may be specified in the Stock Option Agreement), but in
                         any event, no later than the expiration date of the
                         Options.

                (b)      If the Participant is terminated because of death or
                         Disability (or the Participant dies within three (3)
                         months of such termination), then Participant's Options
                         may be exercised only to the extent that such Options
                         would have been exercisable by Participant on the
                         Termination Date and must be exercised by Participant
                         (or Participant's


     -3-
   4
                         legal representative or authorized assignee) no later
                         than twelve (12) months after the Termination Date (or
                         such shorter time period as may be specified in the
                         Stock Option Agreement), but in any event no later than
                         the expiration date of the Options.

                         5.7 Limitations on Exercise. The Committee may specify
a reasonable minimum number of Shares that may be purchased on any exercise of
an Option, provided that such minimum number will not prevent Participant from
exercising the Option for the full number of Shares for which it is then
exercisable.

                         5.8 Limitations on ISOs. The aggregate Fair Market
Value (determined as of the date of grant) of Shares with respect to which ISOs
are exercisable for the first time by a Participant during any calendar year
(under the Plan or under any other incentive stock option plan of the Company or
any Affiliate, Parent or Subsidiary of the Company) shall not exceed $100,000.
If the Fair Market Value of Shares on the date of grant with respect to which
ISOs are exercisable for the first time by a Participant during any calendar
year exceeds $100,000, the Options for the first $100,000 worth of Shares to
become exercisable in such calendar year shall be ISOs and the Options for the
amount in excess of $100,000 that become exercisable in that calendar year shall
be NQSOs. In the event that the Code or the regulations promulgated thereunder
are amended after the Effective Date of the Plan to provide for a different
limit on the Fair Market Value of Shares permitted to be subject to ISOs, such
different limit shall be automatically incorporated herein and shall apply to
any Options granted after the effective date of such amendment.

                         5.9 Modification, Extension or Renewal. The Committee
may modify, extend or renew outstanding Options and authorize the grant of new
Options in substitution therefor, provided that any such action may not, without
the written consent of Participant, impair any of Participant's rights under any
Option previously granted. Any outstanding ISO that is modified, extended,
renewed or otherwise altered shall be treated in accordance with Section 424(h)
of the Code. The Committee may reduce the Exercise Price of outstanding Options
without the consent of Participants affected by a written notice to them;
provided, however, that the Exercise Price may not be reduced below the minimum
Exercise Price that would be permitted under Section 5.4 of the Plan for Options
granted on the date the action is taken to reduce the Exercise Price.

                         5.10 No Disqualification. Notwithstanding any other
provision in the Plan, no term of the Plan relating to ISOs shall be
interpreted, amended or altered, nor shall any discretion or authority granted
under the Plan be exercised, so as to disqualify the Plan under Section 422 of
the Code or, without the consent of the Participant affected, to disqualify any
ISO under Section 422 of the Code.

                6. RESTRICTED STOCK. A Restricted Stock Award is an offer by the
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee shall determine to whom an offer will be made, the number of
Shares the person may purchase, the price to be paid (the "Purchase Price"), the
restrictions to which the Shares shall be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

                         6.1 Form of Restricted Stock Award. All purchases under
a Restricted Stock Award made pursuant to the Plan shall be evidenced by an
Award Agreement ("Restricted Stock Purchase Agreement") that shall be in such
form (which need not be the same for each Participant) as the Committee shall
from time to time approve, and shall comply with and be subject to the terms and
conditions of the Plan. The offer of Restricted Stock shall be accepted by the
Participant's execution and delivery of the Restricted Stock Purchase Agreement
and full payment for the Shares to the Company within thirty (30) days from the
date the Restricted Stock Purchase Agreement is delivered to the person. If such
person does not execute and deliver the Restricted Stock Purchase 


     -4-
   5
Agreement along with full payment for the Shares to the Company within thirty
(30) days, then the offer shall terminate, unless otherwise determined by the
Committee.

                         6.2 Purchase Price. The Purchase Price of Shares sold
pursuant to a Restricted Stock Award shall be determined by the Committee and
shall be at least 85% of the Fair Market Value of the Shares on the date the
Restricted Stock Award is granted, except in the case of a sale to a Ten Percent
Shareholder, in which case the Purchase Price shall be 100% of the Fair Market
Value. Payment of the Purchase Price may be made in accordance with Section 8 of
the Plan.

                         6.3 Restrictions. Restricted Stock Awards shall be
subject to such restrictions as the Committee may impose. The Committee may
provide for the lapse of such restrictions in installments and may accelerate or
waive such restrictions, in whole or part, based on length of service,
performance or such other factors or criteria as the Committee may determine.

                7.       STOCK BONUSES.

                         7.1 Awards of Stock Bonuses. A Stock Bonus is an award
of Shares (which may consist of Restricted Stock) for services rendered to the
Company or any Parent, Subsidiary or Affiliate of the Company. A Stock Bonus may
be awarded for past services already rendered to the Company, or any Parent,
Subsidiary or Affiliate of the Company pursuant to an Award Agreement (the
"Stock Bonus Agreement") that shall be in such form (which need not be the same
for each Participant) as the Committee shall from time to time approve, and
shall comply with and be subject to the terms and conditions of the Plan. A
Stock Bonus may be awarded upon satisfaction of such performance goals as are
set out in advance in the Participant's individual Award Agreement (the
"Performance Stock Bonus Agreement") that shall be in such form (which need not
be the same for each Participant) as the Committee shall from time to time
approve, and shall comply with and be subject to the terms and conditions of the
Plan. Stock Bonuses may vary from Participant to Participant and between groups
of Participants, and may be based upon the achievement of the Company, Parent,
Subsidiary or Affiliate and/or individual performance factors or upon such other
criteria as the Committee may determine.

                         7.2 Terms of Stock Bonuses. The Committee shall
determine the number of Shares to be awarded to the Participant and whether such
Shares shall be Restricted Stock. If the Stock Bonus is being earned upon the
satisfaction of performance goals pursuant to a Performance Stock Bonus
Agreement, then the Committee shall determine: (a) the nature, length and
starting date of any period during which performance is to be measured (the
"Performance Period") for each Stock Bonus; (b) the performance goals and
criteria to be used to measure the performance, if any; (c) the number of Shares
that may be awarded to the Participant; and (d) the extent to which such Stock
Bonuses have been earned. Performance Periods may overlap and Participants may
participate simultaneously with respect to Stock Bonuses that are subject to
different Performance Periods and different performance goals and other
criteria. The number of Shares may be fixed or may vary in accordance with such
performance goals and criteria as may be determined by the Committee. The
Committee may adjust the performance goals applicable to the Stock Bonuses to
take into account changes in law and accounting or tax rules and to make such
adjustments as the Committee deems necessary or appropriate to reflect the
impact of extraordinary or unusual items, events or circumstances to avoid
windfalls or hardships.

                         7.3 Form of Payment. The earned portion of a Stock
Bonus may be paid currently or on a deferred basis with such interest or
dividend equivalent, if any, as the Committee may determine. Payment may be made
in the form of cash, whole Shares, including Restricted Stock, or a combination
thereof, either in a lump sum payment or in installments, all as the Committee
shall determine.


     -5-
   6
                         7.4 Termination During Performance Period. If a
Participant is Terminated during a Performance Period for any reason, then such
Participant shall be entitled to payment (whether in Shares, cash or otherwise)
with respect to the Stock Bonus only to the extent earned as of the date of
Termination in accordance with the Performance Stock Bonus Agreement, unless the
Committee shall determine otherwise.

                8.       PAYMENT FOR SHARE PURCHASES.

                         8.1 Payment. Payment for Shares purchased pursuant to
the Plan may be made in cash (by check) or, where expressly approved for the
Participant by the Committee and where permitted by law:

                 (a)     by cancellation of indebtedness of the Company to the
                         Participant;

                 (b)     by surrender of shares that either: (1) have been owned
                         by Participant for more than six (6) months and have
                         been paid for within the meaning of SEC Rule 144 (and,
                         if such shares were purchased from the Company by use
                         of a promissory note, such note has been fully paid
                         with respect to such shares); or (2) were obtained by
                         Participant in the public market;

                (c)      by tender of a full recourse promissory note having
                         such terms as may be approved by the Committee and
                         bearing interest at a rate sufficient to avoid
                         imputation of income under Sections 483 and 1274 of the
                         Code; provided, however, that Participants who are not
                         employees of the Company shall not be entitled to
                         purchase Shares with a promissory note unless the note
                         is adequately secured by collateral other than the
                         Shares; provided, further, that the portion of the
                         Purchase Price equal to the par value of the Shares, if
                         any, must be paid in cash.

                 (d)     by waiver of compensation due or accrued to Participant
                         for services rendered;

                 (e)     by tender of property;

                 (f)     with respect only to purchases upon exercise of an
                         Option, and provided that a public market for the
                         Company's stock exists:

                                            (1) through a "same day sale"
                                  commitment from Participant and a
                                  broker-dealer that is a member of the National
                                  Association of Securities Dealers (a "NASD
                                  Dealer") whereby the Participant irrevocably
                                  elects to exercise the Option and to sell a
                                  portion of the Shares so purchased to pay for
                                  the Exercise Price, and whereby the NASD
                                  Dealer irrevocably commits upon receipt of
                                  such Shares to forward the Exercise Price
                                  directly to the Company; or

                                            (2) through a "margin" commitment
                                  from Participant and a NASD Dealer whereby
                                  Participant irrevocably elects to exercise the
                                  Option and to pledge the Shares so purchased
                                  to the NASD Dealer in a margin account as
                                  security for a loan from the NASD Dealer in
                                  the amount of the Exercise Price, and whereby
                                  the NASD Dealer irrevocably commits upon
                                  receipt of such Shares to forward the Exercise
                                  Price directly to the Company;
                 or          

     -6-
   7
                (g)      by any combination of the foregoing.

                         8.2 Loan Guarantees. The Committee may help the
Participant pay for Shares purchased under the Plan by authorizing a guarantee
by the Company of a third-party loan to the Participant.

                9.       WITHHOLDING TAXES.

                         9.1 Withholding Generally. Whenever Shares are to be
issued in satisfaction of Awards granted under the Plan, the Company may require
the Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares. Whenever, under the Plan, payments
in satisfaction of Awards are to be made in cash, such payment shall be net of
an amount sufficient to satisfy federal, state, and local withholding tax
requirements.

                         9.2 Stock Withholding. When, under applicable tax laws,
a Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may allow the
Participant to satisfy the minimum withholding tax obligation by electing to
have the Company withhold from the Shares to be issued that number of Shares
having a Fair Market Value equal to the minimum amount required to be withheld,
determined on the date that the amount of tax to be withheld is to be determined
(the "Tax Date"). All elections by a Participant to have Shares withheld for
this purpose shall be made in writing in a form acceptable to the Committee and
shall be subject to the following restrictions:

                 (a)     the election must be made on or prior to the applicable
                         Tax Date;

                 (b)     once made, then except as provided below, the election
                         shall be irrevocable as to the particular Shares as to
                         which the election is made;

                 (c)     all elections shall be subject to the consent or
                         disapproval of the Committee;

                 (d)     if the Participant is an Insider and if the Company is
                         subject to Section 16(b) of the Exchange Act: (1) the
                         election may not be made within six (6) months of the
                         date of grant of the Award, except as otherwise
                         permitted by SEC Rule 16b-3(e) under the Exchange Act,
                         and (2) either (A) the election to use stock
                         withholding must be irrevocably made at least six (6)
                         months prior to the Tax Date (although such election
                         may be revoked at any time at least six (6) months
                         prior to the Tax Date) or (B) the exercise of the
                         Option or election to use stock withholding must be
                         made in the ten (10) day period beginning on the third
                         day following the release of the Company's quarterly or
                         annual summary statement of sales or earnings; and

                 (e)     in the event that the Tax Date is deferred until six
                         (6) months after the delivery of Shares under Section
                         83(b) of the Code, the Participant shall receive the
                         full number of Shares with respect to which the
                         exercise occurs, but such Participant shall be
                         unconditionally obligated to tender back to the Company
                         the proper number of Shares on the Tax Date.

                10.      PRIVILEGES OF STOCK OWNERSHIP.

     -7-
   8
                         10.1 Voting and Dividends. No Participant shall have
any of the rights of a shareholder with respect to any Shares until the Shares
are issued to the Participant. After Shares are issued to the Participant, the
Participant shall be a shareholder and have all the rights of a shareholder with
respect to such Shares, including the right to vote and receive all dividends or
other distributions made or paid with respect to such Shares; provided, that if
such Shares are Restricted Stock, then any new, additional or different
securities the Participant may become entitled to receive with respect to such
Shares by virtue of a stock dividend, stock split or any other change in the
corporate or capital structure of the Company shall be subject to the same
restrictions as the Restricted Stock; provided, further, that the Participant
shall have no right to retain such stock dividends or stock distributions with
respect to Shares that are repurchased at the Participant's original Purchase
Price pursuant to Section 12.

                         10.2 Financial Statements. The Company shall provide
financial statements to each Participant prior to such Participant's purchase of
Shares under the Plan, and to each Participant annually during the period such
Participant has Awards outstanding; provided, however, the Company shall not be
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

                11. TRANSFERABILITY. Awards granted under the Plan, and any
interest therein, shall not be transferable or assignable by Participant, and
may not be made subject to execution, attachment or similar process, otherwise
than by will or by the laws of descent and distribution or as consistent with
the specific Plan and Award Agreement provisions relating thereto. During the
lifetime of the Participant an Award shall be exercisable only by the
Participant, and any elections with respect to an Award, may be made only by the
Participant.

                12. RESTRICTIONS ON SHARES. At the discretion of the Committee,
the Company may reserve to itself and/or its assignee(s) in the Award Agreement
(a) a right of first refusal to purchase all Shares that a Participant (or a
subsequent transferee) may propose to transfer to a third party, and/or (b) a
right to repurchase a portion of or all Shares held by a Participant following
such Participant's Termination at any time within ninety (90) days after the
later of Participant's Termination Date and the date Participant purchases
Shares under the Plan, for cash or cancellation of purchase money indebtedness,
at: (A) with respect to Shares that are "Vested" (as defined in the Award
Agreement), the higher of: (l) Participant's original Purchase Price, or (2) the
Fair Market Value of such Shares on Participant's Termination Date, provided,
that such right of repurchase (i) must be exercised as to all such "Vested"
Shares unless a Participant consents to the Company's repurchase of only a
portion of such "Vested" Shares and (ii) terminates when the Company's
securities become publicly traded; or (B) with respect to Shares that are not
"Vested" (as defined in the Award Agreement), at the Participant's original
Purchase Price, provided, that the right to repurchase at the original Purchase
Price lapses at the rate of at least 20% per year over 5 years from the date the
Shares were purchased (or from the date of grant of options in the case of
Shares obtained pursuant to a Stock Option Agreement and Stock Option Exercise
Agreement), and if the right to repurchase is assignable, the assignee must pay
the Company, upon assignment of the right to repurchase, cash equal to the
excess of the Fair Market Value of the Shares over the original Purchase Price.

                13. CERTIFICATES. All certificates for Shares or other
securities delivered under the Plan shall be subject to such stock transfer
orders, legends and other restrictions as the Committee may deem necessary or
advisable, including restrictions under any applicable federal, state or foreign
securities law, or any rules, regulations and other requirements of the SEC or
any stock exchange or automated quotation system upon which the Shares may be
listed.

                14. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock



     -8-
   9
powers or other instruments of transfer approved by the Committee, appropriately
endorsed in blank, with the Company or an agent designated by the Company to
hold in escrow until such restrictions have lapsed or terminated, and the
Committee may cause a legend or legends referencing such restrictions to be
placed on the certificates. Any Participant who is permitted to execute a
promissory note as partial or full consideration for the purchase of Shares
under the Plan shall be required to pledge and deposit with the Company all or
part of the Shares so purchased as collateral to secure the payment of
Participant's obligation to the Company under the promissory note; provided,
however, that the Committee may require or accept other or additional forms of
collateral to secure the payment of such obligation and, in any event, the
Company shall have full recourse against the Participant under the promissory
note notwithstanding any pledge of the Participant's Shares or other collateral.
In connection with any pledge of the Shares, Participant shall be required to
execute and deliver a written pledge agreement in such form as the Committee
shall from time to time approve. The Shares purchased with the promissory note
may be released from the pledge on a prorata basis as the promissory note is
paid.

                15. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any
time or from time to time, authorize the Company, with the consent of the
respective Participants, to issue new Awards in exchange for the surrender and
cancellation of any or all outstanding Awards. The Committee may at any time buy
from a Participant an Award previously granted with payment in cash, Shares
(including Restricted Stock) or other consideration, based on such terms and
conditions as the Committee and the Participant shall agree.

                16. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award
shall not be effective unless such Award is in compliance with all applicable
federal and state securities laws, rules and regulations of any governmental
body, and the requirements of any stock exchange or automated quotation system
upon which the Shares may then be listed, as they are in effect on the date of
grant of the Award and also on the date of exercise or other issuance.
Notwithstanding any other provision in the Plan, the Company shall have no
obligation to issue or deliver certificates for Shares under the Plan prior to
(a) obtaining any approvals from governmental agencies that the Company
determines are necessary or advisable, and/or (b) completion of any registration
or other qualification of such shares under any state or federal law or ruling
of any governmental body that the Company determines to be necessary or
advisable. The Company shall be under no obligation to register the Shares with
the SEC or to effect compliance with the registration, qualification or listing
requirements of any state securities laws, stock exchange or automated quotation
system, and the Company shall have no liability for any inability or failure to
do so.

                17. NO OBLIGATION TO EMPLOY. Nothing in the Plan or any Award
granted under the Plan shall confer or be deemed to confer on any Participant
any right to continue in the employ of, or to continue any other relationship
with, the Company or any Parent, Subsidiary or Affiliate of the Company or limit
in any way the right of the Company or any Parent, Subsidiary or Affiliate of
the Company to terminate Participant's employment or other relationship at any
time, with or without cause.

                18.      CORPORATE TRANSACTIONS.

                         18.1 Corporate Transactions. In the event of a
Corporate Transaction (as defined in this Section 18.1), the exercisability of
each Option shall be automatically accelerated so that each Option shall,
immediately before the specified effective date for the Corporate Transaction,
become fully exercisable with respect to the total number of Shares and may be
exercised for all or any portion of such Shares; provided, that an Option shall
not be accelerated if and to the extent that such Option is, in connection with
the Corporate Transaction, either to be assumed by the successor corporation or
parent thereof or to be replaced with a comparable option to purchase shares of
the capital stock of the successor corporation or parent thereof. The
determination of comparability shall be made by the Board or the Committee, and
the Board or the Committee's determination shall be final, binding and

     -9-
   10
conclusive. Upon the consummation of a Corporate Transaction, all outstanding
Options shall, to the extent not previously exercised or assumed by the
successor corporation or its parent, terminate and cease to be exercisable.

                                 "Corporate Transaction" means (i) a merger or
acquisition in which the Company is not the surviving entity (except for a
transaction the principal purpose of which is to change the State in which the
Company is incorporated), (ii) the sale, transfer or other disposition of all or
substantially all of the assets of the Company or (iii) any other corporate
reorganization or business combination that is not approved by the Board and in
which the beneficial ownership of 50% or more of the Company's outstanding
voting stock is transferred.

                         18.2 Dissolution. 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 that
Options have not been previously exercised, such Options will terminate
immediately prior to the consummation of such proposed action.

                         18.3 Assumption of Awards by the Company. The Company,
from time to time, also may substitute or assume outstanding awards granted by
another company, whether in connection with an acquisition of such other company
or otherwise, by either (a) granting an Option under this Plan in substitution
of such other company's Option, or (b) assuming such Option as if it had been
granted under this Plan if the terms of such assumed Option could be applied to
an Option granted under this Plan. Such substitution or assumption shall be
permissible if the holder of the substituted or assumed Option would have been
eligible to be granted an Option under the Plan if the other company had applied
the rules of the Plan to such grant. In the event the Company assumes an Option
granted by another company, the terms and conditions of such Option shall remain
unchanged (except that the Exercise Price and the number and nature of Shares
issuable upon exercise of any such option will be adjusted appropriately
pursuant to Section 424(a) of the Code). In the event the Company elects to
grant a new Option rather than assuming an existing option, such new Option may
be granted with a similarly adjusted Exercise Price.

                         19. ADOPTION AND SHAREHOLDER APPROVAL. The Plan shall
become effective on the closing of the first registration of the Company's
Common Stock for sale to the public under the Securities Act (the "Effective
Date"). The Plan shall be approved by the shareholders of the Company (excluding
Shares issued pursuant to this Plan), consistent with applicable laws, within
twelve (12) months before or after the date the Plan is adopted by the Board.
Upon the Effective Date, the Board may grant Awards pursuant to the Plan;
provided, however, that: (a) no Option may be exercised prior to initial
shareholder approval of the Plan; (b) no Option granted pursuant to an increase
in the number of Shares approved by the Board shall be exercised prior to the
time such increase has been approved by the shareholders of the Company; and (c)
in the event that shareholder approval is not obtained within the time period
provided herein, all Awards granted hereunder shall be canceled, any Shares
issued pursuant to any Award shall be canceled and any purchase of Shares
hereunder shall be rescinded. After the Company becomes subject to Section 16(b)
of the Exchange Act, the Company will comply with the requirements of Rule 16b-3
(or its successor), as amended, with respect to shareholder approval.

                20. TERM OF PLAN. The Plan will terminate ten (10) years from
the date the Plan is adopted by the Board or, if earlier, the date of
shareholder approval.

                21. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time
terminate or amend the Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to the Plan; provided, however, that the Board shall not, without the approval
of the shareholders of the Company, amend the Plan in any manner that requires
such shareholder approval pursuant to 


     -10-
   11
the Code or the regulations promulgated thereunder as such provisions apply to
ISO plans or pursuant to the Exchange Act or Rule 16b-3 (or its successor), as
amended, thereunder.

                22. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of the Plan
by the Board, the submission of the Plan to the shareholders of the Company for
approval, nor any provision of the Plan shall be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under the Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.

                  2.2 Expiration. The Option shall expire on the Expiration Date

         3. TERMINATION.

                  3.1 Termination for Any Reason Except Death or Disability. If
Participant is Terminated for any reason, except death or Disability, the
Option, to the extent (and only to the extent) that it would have been

any event no later than the Expiration Date.

                  3.2 Termination Because of Death or Disability. If Participant
is Terminated because of death or Disability of Participant, the Option, to the

the Expiration Date.

                  3.3 No Obligation to Employ. Nothing in the Plan or this

the Company, or limit in any way the right of the Company or any Parent,
Subsidiary or Affiliate of the Company to terminate Participant's employment or
other relationship at any time, with or without cause.

         4. MANNER OF EXERCISE.

                  4.1 Stock Option Exercise Agreement. To exercise this Option,
Participant (or in the case of exercise after Participant's death, Participant's
executor, administra tor, heir or legatee, as the case may be) must deliver to
the Company an executed stock option exercise agreement in the form attached
hereto as Exhibit A, or in such other form as may be approved by the Company
from time to time (the "Exercise Agreement"), which shall set forth, inter alia,
Participant's election to exercise the Option, the number of Shares being
purchased, any restrictions imposed on the Shares and any representations,
warranties and agreements regarding Participant's investment intent and access
to information as may be required by the Company to comply with applicable
securities laws. If someone other than Participant exercises the Option, then
such person must submit documentation reasonably acceptable to the Company that
such person has the right to exercise the Option.

                  4.2 Limitations on Exercise. The Option may not be exercised
unless such exercise is in compliance with all applicable federal and state
securities laws, as they are in effect on the date of exercise. The Option may
not be exercised as to fewer than 100 Shares unless it is exercised as to all
Shares as to which the Option is then exercisable.

                  4.3 Payment. The Exercise Agreement shall be accompanied by
full payment of the Exercise Price for the Shares being purchased in cash (by
check), or where permitted by law:

         (a) by cancellation of indebtedness of the Company to the Participant;

         (b) by surrender of shares of the Company's Common Stock that either:
         (1) have been owned by Participant for more than six (6) months and
         have been paid for within the meaning of SEC Rule 144 and, if such
         shares were purchased from the Company by use of a promissory note,
         such note has been fully paid with respect to such shares); or (2) were
         obtained by Participant in the open public market; and (3) are clear of
         all liens, claims, encumbrances or security interests;

         (c) by tender of a full recourse promissory note having such terms as
         may be approved by the Committee and bearing interest at a rate
         sufficient to avoid imputation of income under Sections 483 and 1274 of
         the Code; provided, however, that Participants who are not employees of
         the Company shall not be entitled to purchase Shares with a promissory
         note unless the note is adequately secured by collateral other than the
         Shares; provided, further, that the portion of the Purchase Price equal
         to the par value of the Shares, if any, must be paid in cash.

         (d) by waiver of compensation due or accrued to Participant for
         services rendered;

         (d) by tender of property;

         (f) provided that a public market for the Company's stock exists, (1)
         through a "same day sale" commitment from Participant and a
         broker-dealer that is a member of the National Association of
         Securities Dealers (a "NASD Dealer") whereby Participant irrevocably
         elects to exercise the Option and to sell a portion of the Shares so
         purchased to pay for the exercise price and whereby the NASD Dealer
         irrevocably commits upon receipt of such Shares to forward the exercise
         price directly to the Company, or (2) through a "margin" commitment
         from Participant and a NASD -- Dealer whereby Participant irrevocably
         elects to exercise the Option and to pledge the Shares so purchased to
         the NASD Dealer in a margin account as security for a loan from the
         NASD Dealer in the amount of the exercise price, and whereby the NASD
         Dealer irrevocably commits upon receipt of such Shares to forward the
         exercise price directly to the Company; or

         (e) by any combination of the foregoing.

         4.4 Tax Withholding. Prior to the issuance of the Shares upon exercise
of the Option, Participant must pay or provide for any applicable federal or
state withholding obligations of the Company. If the Committee permits,
Participant may provide for payment of withholding taxes upon exercise of the
Option by requesting that the Company retain Shares with a Fair Market Value
equal to the minimum amount of taxes required to be withheld. In such case, the
Company shall issue the net number of Shares to the Participant by deducting the
Shares retained from the Shares issuable upon exercise.

         4.5 Issuance of Shares. Provided that the Exercise Agreement and
payment are in form and substance satisfactory to counsel for the Company, the
Company shall

issue the Shares registered in the name of Participant, Participant's authorized
assignee, or Participant's legal representative, and shall deliver certificates
representing the Shares with the appropriate legends affixed thereto.

         5. NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES. If the Option is
an ISO, and if Participant 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, and (2) the date one year after transfer of such Shares
to Participant upon exercise of the Option, Participant shall immediately notify
the Company in writing of such disposition. Participant agrees that Participant
may be subject to income tax withholding by the Company on the compensation
income recognized by Participant from the early disposition by payment in cash
or out of the current wages or other compensation payable to Participant.

         6. COMPLIANCE WITH LAWS AND REGULATIONS. The exercise of the Option and
the issuance and transfer of Shares shall be subject to compliance by the
Company and Partici pant with all applicable requirements of federal and state
securities laws and with all applicable requirements of any stock exchange on
which the Company's Common Stock may be listed at the time of such issuance or
transfer. Participant understands that the Company is under no obliga tion to
register or qualify the Shares with the Securities and Exchange Commission, any
state securities commission or any stock exchange to effect such compliance.

         7. NONTRANSFERABILITY OF OPTION. The Option may not be transferred in
any manner other than by will or by the laws of descent and distribution and may
be exercised during the lifetime of Participant only by Participant. The terms
of the Option shall be binding upon the executors, administrators, successors
and assigns of Participant.

         8. TAX CONSEQUENCES. Set forth below is a brief summary as of the Date
of Grant of some of the federal and California tax consequences of exercise of
the Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY
INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. PARTICIPANT
SHOULD CONSULT A TAX ADVISOR BEFORE EXERCISING THE OPTION OR DISPOSING OF THE
SHARES.

                  8.1 Exercise of ISO. If the Option qualifies as an ISO, there
will be no regular federal or California 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 a tax
preference item for federal income tax purposes and may subject the Participant
to the alternative minimum tax in the year of exercise.

                  8.2 Exercise of Nonqualified Stock Option. If the Option does
not qualify as an ISO, there may be a regular federal and California income tax
liability upon the

exercise of the Option. Participant 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. The Company will be required to withhold from Participant's
compensation or collect from Participant and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.


                  8.3 Disposition of Shares. If the Shares are held for more
than twelve (12) months after the date of the transfer of the Shares pursuant to
the exercise of the Option (and, in the case of an ISO, are disposed of more
than two years after the Date of Grant), any gain realized on disposition of the
Shares will be treated as long term capital gain for federal and California
income tax purposes. If Shares purchased under an ISO are disposed of within one
year of exercise 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 excess, if any, of the Fair Market Value of
the Shares on the date of exercise over the Exercise Price. The Company will be
required to withhold from Participant's compensation or collect from Participant
and pay to the applicable taxing authorities an amount equal to a percentage of
this compensation income at the time of exercise.

         9. PRIVILEGES OF STOCK OWNERSHIP. Participant shall not have any of the
rights of a shareholder with respect to any Shares until Participant exercises
the Option and pays the Exercise Price.

         10. INTERPRETATION. Any dispute regarding the interpretation of this
Agreement shall be submitted by Participant or the Company to the Committee for
review. The resolution of such a dispute by the Committee shall be final and
binding on the Company and Participant.

         11. ENTIRE AGREEMENT. The Plan is incorporated herein by reference.
This Agreement and the Plan constitute the entire agreement of the parties and
supersede all prior undertakings and agreements with respect to the subject
matter hereof.

         12. NOTICES. Any notice required to be given or delivered to the
Company under the terms of this Agreement shall be in writing and addressed to
the Corporate Secretary of the Company at its principal corporate offices. Any
notice required to be given or delivered to Participant shall be in writing and
addressed to Participant at the address indicated above or to such other address
as such party may designate in writing from time to time to the Company. All
notices shall be deemed to have been given or delivered upon: personal delivery;
three (3) days after deposit in the United States mail by certified or
registered mail (return receipt requested); one (1) business day after deposit

transmission by rapifax or telecopier.

         13. SUCCESSORS AND ASSIGNS. The Company may assign any of its rights

the successors and assigns of the Company. Subject to the restrictions on

         14. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of California.

         15. ACCEPTANCE. Participant hereby acknowledges receipt of a copy of
the Plan and this Agreement. Participant has read and understands the terms and
provisions thereof, and accepts the Option subject to all the terms and
conditions of the Plan and this Agreement. Participant acknowledges that there
