        The following constitute the provisions of the 1993 Employee Stock
Purchase Plan of Integrated Silicon Solution, Inc.

        1. Purpose. The purpose of the Plan is to provide employees of the
Company and its Designated Subsidiaries with an opportunity to purchase Common
Stock of the Company through accumulated payroll deductions. It is the intention
of the Company to have the Plan qualify as an "Employee Stock Purchase Plan"
under Section 423 of the Internal Revenue Code of 1986, as amended. The
provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

continuing intact while the individual is on sick leave or other leave of
absence approved by the Company. Where the period of leave exceeds 90 days and

dealer but selling prices are not reported, its Fair Market Value shall be the
mean of the closing bid and asked prices for the Common Stock on the date of
such determination, as reported in The Wall Street Journal or such other source
as the Board deems reliable, or;

               (3)Notwithstanding paragraphs (1) and (2), in the case of an
Offering Period commencing substantially concurrent with the Company's initial
public offering, the Fair Market Value may be determined by the Board to be
equal to the initial price to the public of shares of Common Stock in such
offering; or

               (4)In the absence of an established market for the Common Stock,
the Fair Market Value thereof shall be determined in good faith by the Board.

           (a) Any Employee (as defined in Section 2(g)), who shall be employed
by the Company on a given Enrollment Date shall be eligible to participate in
the Plan.

           (b) Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) if, immediately after the
grant, such Employee (or any other person whose stock would be attributed to
such Employee pursuant to Section 424(d) of the Code) would own capital stock of
the Company and/or hold outstanding options to purchase such stock possessing
five percent (5%) or more of the total combined voting power or value of all
classes of the capital stock of the Company or of any Subsidiary, or (ii) which
permits his or her rights to purchase stock under all employee stock purchase
plans of the Company and its subsidiaries to accrue at a rate which exceeds

year in which such option is outstanding at any time.

        4. Offering Periods. The Plan shall be implemented by consecutive,
overlapping Offering Periods with a new Offering Period commencing on the first
Trading Day on or after April 1 and October 1 each year, or on such other dates
as the Board shall determine, and continuing thereafter until terminated in
accordance with Section 19 hereof. The Board shall have the power to change the
duration of Offering Periods (including the commencement and termination dates
thereof) with respect to future offerings without stockholder approval if such
change is announced at least five (5) days prior to the scheduled beginning of
the first Offering Period to be affected thereafter.

        5. Participation.

           (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

           (b) Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

                                      -3-
<PAGE>

        6. Payroll Deductions.

           (a) At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding ten percent (10%) of the
Compensation which he or she receives on each pay day during the Offering
Period, and the aggregate of such payroll deductions during the Offering Period
shall not exceed ten percent (10%) of the participant's Compensation during said
Offering Period.

           (b) All payroll deductions made for a participant shall be credited
to his or her account under the Plan and will be withheld in whole percentages
only. A participant may not make any additional payments into such account.

           (c) A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

           (d) Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to 0% at such time during any Purchase
Period which is scheduled to end during the current calendar year (the "Current
Purchase Period") that the aggregate of all payroll deductions which were
previously used to purchase stock under the Plan in a prior Purchase Period
which ended during that calendar year plus all payroll deductions accumulated
with respect to the Current Purchase Period equal $21,250. Payroll deductions
shall recommence at the rate provided in such participant's subscription
agreement at the beginning of the first Purchase Period which is scheduled to
end in the following calendar year, unless terminated by the participant as
provided in Section 10 hereof.

           (e) At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but will not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

        7. Grant of Option. On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise

                                      -4-
<PAGE>

Date by the applicable Purchase Price; provided that in no event shall an
Employee be permitted to purchase during each Purchase Period more than a number
of Shares determined by dividing $12,500 by the Fair Market Value of a share of
the Company's Common Stock on the Enrollment Date (except if there is only one
Purchase Period in a calendar year, in which case the dollar limit in the
preceding equation shall be $25,000 instead of $12,500), and provided further
that such purchase shall be subject to the limitations set forth in Sections
3(b) and 12 hereof. Exercise of the option shall occur as provided in Section 8
hereof, unless the participant has withdrawn pursuant to Section 10 hereof, and
shall expire on the last day of the Offering Period.

        8. Exercise of Option. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares will
be exercised automatically on the Exercise Date, and the maximum number of full
shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares will be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

        9. Delivery. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

        10. Withdrawal; Termination of Employment.

            (a) A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan. All of the participant's payroll deductions
credited to his or her account will be paid to such participant promptly after
receipt of notice of withdrawal and such participant's option for the Offering
Period will be automatically terminated, and no further payroll deductions for
the purchase of shares will be made for such Offering Period. If a participant
withdraws from an Offering Period, payroll deductions will not resume at the
beginning of the succeeding Offering Period unless the participant delivers to
the Company a new subscription agreement.

            (b) Upon a participant's ceasing to be an Employee (as defined in
Section 2(g) hereof), for any reason, including by virtue of him or her having
failed to remain an Employee of the Company for at least twenty (20) hours per
week during an Offering Period in which the Employee is a participant, he or she
will be deemed to have elected to withdraw from the Plan and the payroll
deductions credited to such participant's account during the Offering Period but
not yet used to exercise the option will be returned to such participant or, in
the case of his or her death, to the person or persons entitled thereto under
Section 14 hereof, and such participant's option will be automatically
terminated.

                                      -5-
<PAGE>

        11. Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

        12. Stock.

            (a) The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 2,250,000 Shares,
subject to adjustment upon changes in capitalization of the Company as provided
in Section 18 hereof. If, on a given Exercise Date, the number of Shares with
respect to which options are to be exercised exceeds the number of shares then
available under the Plan, the Company shall make a pro rata allocation of the
Shares remaining available for purchase in as uniform a manner as shall be
practicable and as it shall determine to be equitable.

            (b) The participant will have no interest or voting right in shares
covered by his option until such option has been exercised.

            (c) Shares to be delivered to a participant under the Plan will be
registered in the name of the participant or in the name of the participant and
his or her spouse.

        13. Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties. Members of the Board
who are eligible Employees are permitted to participate in the Plan, provided
that:

                (1) Members of the Board who are eligible to participate in the
Plan may not vote on any matter affecting the administration of the Plan or the
grant of any option pursuant to the Plan.

                (2) If a Committee is established to administer the Plan, no
member of the Board who is eligible to participate in the Plan may be a member
of the Committee.

        14. Designation of Beneficiary.

            (a) A participant may file a written designation of a beneficiary
who is to receive any shares and cash, if any, from the participant's account
under the Plan in the event of such participant's death subsequent to an
Exercise Date on which the option is exercised but prior to delivery to such
participant of such shares and cash. In addition, a participant may file a
written designation of a beneficiary who is to receive any cash from the
participant's account under the Plan in the event of such participant's death
prior to exercise of the option. If a participant is married and the designated
beneficiary is not the spouse, spousal consent shall be required for such
designation to be effective.

            (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary

                                      -6-
<PAGE>

validly designated under the Plan who is living at the time of such
participant's death, the Company shall deliver such shares and/or cash to the
executor or administrator of the estate of the participant, or if no such
executor or administrator has been appointed (to the knowledge of the Company),
the Company, in its discretion, may deliver such shares and/or cash to the
spouse or to any one or more dependents or relatives of the participant, or if
no spouse, dependent or relative is known to the Company, then to such other
person as the Company may designate.

        15. Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

        16. Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

        17. Reports. Individual accounts will be maintained for each participant
in the Plan. Statements of account will be given to participating Employees at
least annually, which statements will set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

        18. Adjustments Upon Changes in Capitalization, Dissolution,
Liquidation, Merger or Asset Sale.

            (a) Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the Reserves as well as the price per share of
Common Stock covered by each option under the Plan which has not yet been
exercised shall be proportionately adjusted for any increase or decrease in the
number of issued shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of shares of Common Stock
effected without receipt of consideration by the Company; provided, however,
that conversion of any convertible securities of the Company shall not be deemed
to have been "effected without receipt of consideration". Such adjustment shall
be made by the Board, whose determination in that respect shall be final,
binding and conclusive. Except as expressly provided herein, no issuance by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock subject
to an option.

            (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Periods will terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

            (c) Merger or Asset Sale. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each

                                      -7-
<PAGE>

option under the Plan shall be assumed or an equivalent option shall be
substituted by such successor corporation or a parent or subsidiary of such
successor corporation. In the event that the successor corporation refuses to
assume or substitute for the option, any Purchase Periods than in progress shall
be shortened by setting a new Exercise Date (the "New Exercise Date") and any
Offering Periods then in progress shall end on the New Exercise Date. The New
Exercise Date shall be prior to the date of the Company's proposed sale or
merger. If the Board sets a new Exercise Date, the Board shall notify each
participant in writing, at least ten (10) business days prior to the New
Exercise Date, that the Exercise Date for his option has been changed to the New
Exercise Date and that his option will be exercised automatically on the New
Exercise Date, unless prior to such date he has withdrawn from the Offering
Periods as provided in Section 10 hereof.

        19. Amendment or Termination.

            (a) The Board of Directors of the Company may at any time and for
any reason terminate or amend the Plan. Except as provided in Section 18 hereof,
no such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Plan is in the best
interests of the Company and its stockholders. Except as provided in Section 18
hereof, no amendment may make any change in any option theretofore granted which
adversely affects the rights of any participant. To the extent necessary to
comply with Rule 16b-3 or under Section 423 of the Code (or any successor rule
or provision or any other applicable law or regulation), the Company shall
obtain stockholder approval in such a manner and to such a degree as required.

            (b) Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

        20. Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

        21. Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, and the requirements of any stock exchange upon which
the shares may

                                      -8-
<PAGE>

then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

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

        22. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 19 hereof.

        23. Automatic Transfer to Low Price Offering Period. If the Fair Market
Value of the Common Stock on any Exercise Date in an Offering Period is lower
than the Fair Market Value of the Common Stock on the Enrollment Date of such
Offering Period, then all participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the exercise
of their option on such Exercise Date and automatically re-enrolled in the
immediately following Offering Period as of the first day thereof.

               to automatically exercise my option.

        4.     I have received a copy of the complete "Integrated Silicon

               pursuant to the Plan within 2 years after the Enrollment Date
               (the first day of the Offering Period during which I purchased
               such shares) or one year after the Exercise Date, I will be
               treated for federal income tax purposes as having received
               ordinary income at the time of such disposition in an amount
               equal to the excess of the fair market value of the shares at

<PAGE>

               the time such shares were purchased over the price which I paid
               for the shares. I HEREBY AGREE TO NOTIFY THE COMPANY IN WRITING
               WITHIN 30 DAYS AFTER THE DATE OF ANY DISPOSITION OF MY SHARES AND
               I WILL MAKE ADEQUATE PROVISION FOR FEDERAL, STATE OR OTHER TAX
               WITHHOLDING OBLIGATIONS, IF ANY, WHICH ARISE UPON THE DISPOSITION
               OF THE COMMON STOCK. The Company may, but will not be obligated
               to, withhold from my compensation the amount necessary to meet
               any applicable withholding obligation including any withholding
               necessary to make available to the Company any tax deductions or
               benefits attributable to sale or early disposition of Common
               Stock by me. If I dispose of such shares at any time after the
               expiration of the 2-year and 1-year holding periods, I understand
               that I will be treated for federal income tax purposes as having
               received income only at the time of such disposition, and that
               such income will be taxed as ordinary income only to the extent
               of an amount equal to the lesser of (1) the excess of the fair
               market value of the shares at the time of such disposition over
               the purchase price which I paid for the shares, or (2) 15% of the
               fair market value of the shares on the first day of the Offering
               Period. The remainder of the gain, if any, recognized on such
               disposition will be taxed as capital gain.

        7.     I hereby agree to be bound by the terms of the Employee Stock
               Purchase Plan. The effectiveness of this Subscription Agreement
               is dependent upon my eligibility to participate in the Employee
               Stock Purchase Plan.

        8.     In the event of my death, I hereby designate the following as my
               beneficiary(ies) to receive all payments and shares due me under

                  (ix)  to reduce the exercise price of any Option to the then

                                      -3-
<PAGE>
      6.    Term of Plan. The Plan shall become effective upon its adoption by
the Board of Directors. It shall continue in effect until terminated under
Section 14 of the Plan.

      7.    Term of Option. The term of each Option shall be the term stated in
the Option Agreement.

      8.    Option Exercise Price and Consideration.

            (a)   The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Administrator.

            (b)   The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator and may consist entirely of (1) cash, (2) check, (3)
promissory note, (4) other Shares which (x) in the case of Shares acquired upon
exercise of an Option either have been owned by the Optionee for more than six
months on the date of surrender or were not acquired, directly or indirectly,
from the Company, and (y) have a Fair Market Value on the date of surrender
equal to the aggregate exercise price of the Shares as to which said Option
shall be exercised, (5) authorization from the Company to retain from the total
number of Shares as to which the Option is exercised that number of Shares
having a Fair Market Value on the date of exercise equal to the exercise price
for the total number of Shares as to which the Option is exercised, (6) by
delivering an irrevocable subscription agreement for the Shares which
irrevocably obligates the option holder to take and pay for the Shares not more
than twelve months after the date of delivery of the subscription agreement, (7)
delivery of a properly executed exercise notice together with such other
documentation as the Administrator and the broker, if applicable, shall require
to effect an exercise of the Option and delivery to the Company of the sale or
loan proceeds required to pay the exercise price; (8) any combination of the
foregoing methods of payment, (9) or such other consideration and method of
payment for the issuance of Shares to the extent permitted under applicable
laws.

      9.    Exercise of Option.

            (a)   Procedure for Exercise; Rights as a Stockholder. Any Option
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Board, including performance criteria with respect to the
Company and/or the Optionee, and as shall be permissible under the terms of the
Plan.

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

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

                                      -4-
<PAGE>
upon exercise of the Option. No adjustment will be made for a dividend or other
right for which the record date is prior to the date the stock certificate is
issued, except as provided in Section 12 of the Plan.

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

            (b)   Termination of Employment. In the event of termination of an
Optionee's Continuous Status as an Employee or Consultant, such Optionee may,
but only within thirty (30) days (or within such other period of time as is
determined by the Board), after the date of such termination (but in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement), exercise his Option to the extent that Optionee was entitled
to exercise it at the date of such termination. To the extent that Optionee was
not entitled to exercise the Option at the date of such termination, or if
Optionee does not exercise such Option to the extent so entitled within the time
specified herein, the Option shall terminate.

            (c)   Disability of Optionee. Notwithstanding the provisions of
Section 9(b) above, in the event of termination of an Optionee's Continuous
Status as an Employee or Consultant as a result of his total and permanent
disability (as defined in Section 22(e)(3) of the Code), Optionee may, but only
within twelve (12) months from the date of such termination (but in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement), exercise the Option to the extent otherwise entitled to
exercise it at the date of such termination. To the extent that Optionee was not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option to the extent so entitled within the time specified
herein, the Option shall terminate.

            (d)   Death of Optionee. Notwithstanding the provisions of Section
9(b) above, in the event of the death of an Optionee while Optionee is an
Employee or Consultant, the Option may be exercised at any time within twelve
(12) months following the date of death (but in no event later than the
expiration date of the term of such Option as set forth in the Option
Agreement), by the Optionee's estate or by a person who acquired the right to
exercise the Option by bequest or inheritance, but only to the extent the
Optionee was entitled to exercise the Option at the date of death. To the extent
that Optionee was not entitled to exercise the Option at the date of
termination, or if Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate.

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

      10.   Non-Transferability of Options. Unless otherwise provided for by the
Administrator, the Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.

      11.   Stock Withholding to Satisfy Withholding Tax Obligations. At the
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph. When an Optionee incurs tax liability in
connection with an Option, which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount

                                      -5-
<PAGE>
required to be withheld under applicable tax laws, the Optionee may satisfy the
withholding tax obligation by electing to have the Company withhold from the
Shares to be issued upon exercise of the Option, if any, that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined.

      12.   Adjustments Upon Changes in Capitalization, Merger or Asset Sale.
Subject to any required action by the stockholders of the Company, the number of
shares of Common Stock covered by each outstanding Option, and the number of
shares of Common Stock which have been authorized for issuance under the Plan
but as to which no Options have yet been granted or which have been returned to
the Plan upon cancellation or expiration of an Option, as well as the price per
share of Common Stock covered by each such outstanding Option, shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of issued shares of Common Stock effected
without receipt of consideration by the Company; provided, however, that
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." Such adjustment shall be
made by the Board, whose determination in that respect shall be final, binding
and conclusive. Except as expressly provided herein, no issuance by the Company
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares of Common Stock subject to an
Option.

            In the event of the proposed dissolution or liquidation of the
Company, the Board shall notify the Optionee at least fifteen (15) days prior to
such proposed action. To the extent it has not been previously exercised, the
Option will terminate immediately prior to the consummation of such proposed
action. In the event of a merger of the Company with or into another
corporation, or the sale of all or substantially all of the Company's assets,
the Option shall be assumed or an equivalent option shall be substituted by such
successor corporation or a parent or subsidiary of such successor corporation.
In the event that such successor corporation does not agree to assume the Option
or to substitute an equivalent option, the Board shall, in lieu of such
assumption or substitution, provide for the Optionee to have the right to
exercise the Option as to all of the Optioned Stock, including Shares as to
which the Option would not otherwise be exercisable. If the Board makes an
Option fully exercisable in lieu of assumption or substitution in the event of a
merger, the Board shall notify the Optionee that the Option shall be fully
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option will terminate upon the expiration of such period.

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

      14.   Amendment and Termination of the Plan.

            (a)   Amendment and Termination. The Board may at any time amend,
alter, suspend or discontinue the Plan, but no amendment, alteration, suspension
or discontinuation shall be made which would impair the rights of any Optionee
under any grant theretofore made, without his or her consent.

                                      -6-
<PAGE>
            (b)   Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

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

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

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

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

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

Grant (the "Exercise Price"), subject to the terms and conditions of the Plan,
which is incorporated herein by reference. Subject to Section 14(b) of the Plan,
in the event of a conflict between the terms and conditions of the Plan and the
terms and conditions of this Option Agreement, the terms and conditions of the
Plan shall prevail.

      2.    Exercise of Option.

            (1)   Right to Exercise. This Option is exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

            (2)   Method of Exercise. This Option is exercisable by delivery of
an exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to Chief Financial Officer. The Exercise Notice
shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanied by such aggregate
Exercise Price.

            No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

      3.    Method of Payment. Payment of the aggregate Exercise Price shall be
by any of the methods set forth in Section 8(b) of the Plan.

      4.    Non-Transferability of Option. This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee. The terms
of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

      5.    Term of Option. This Option may be exercised only within the term
set out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

      6.    Tax Consequences. Some of the federal tax consequences relating to
this Option, as of the date of this Option, are set forth below. THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR
DISPOSING OF THE SHARES.

            (1)   Exercising the Option. The Optionee may incur regular federal
income tax liability upon exercise of an NSO. The Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the Fair Market Value of the Exercised Shares on the
date of exercise over their aggregate Exercise Price. If the Optionee is an
Employee or a former Employee, the Company will be required to withhold from his
or her compensation or collect from Optionee and pay to the applicable taxing
authorities an amount in cash equal to a percentage of this compensation income
at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered at the time of
exercise.

            (2)   Disposition of Shares. If the Optionee holds NSO Shares for at
least one year, any gain realized on disposition of the Shares will be treated
as long-term capital gain for federal income tax purposes.
