                              QUINTUS CORPORATION

                             1995 STOCK OPTION PLAN

                                  ARTICLE ONE

                               GENERAL PROVISIONS

     I.   PURPOSE OF THE PLAN

          This 1995 Stock Option Plan is intended to promote the interests of
Quintus Corporation, a Delaware corporation, by providing eligible persons with
the opportunity to acquire a proprietary interest, or otherwise increase their
proprietary interest, in the Corporation as an incentive for them to remain in
the service of the Corporation.

          Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II.  ADMINISTRATION OF THE PLAN

          A.   The Plan shall be administered by the Board. However, any or all
administrative functions otherwise exercisable by the Board may be delegated to
the Committee. Members of the Committee shall serve for such period of time as
the Board may determine and shall be subject to removal by the Board at any
time. The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to the Committee.

          B.   The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to
make such determinations under, and issue such interpretations of, the Plan and
any outstanding options as it may deem necessary or advisable. Decisions of the
Plan Administrator shall be final and binding on all parties who have an
interest in the Plan or any option or shares issued thereunder.

     III. ELIGIBILITY

          A.   The persons eligible to receive option grants under the Plan are
as follows:

                    (i)       Employees,

                    (ii)      non-employee members of the Board or the
     non-employee members of the board of directors of any Parent or Subsidiary,
     and

                    (iii)     consultants who provide services to the
     Corporation (or any Parent or Subsidiary)

          B.   The Plan Administrator shall have full authority to determine
which eligible persons are to receive option grants under the Plan, the time or
times when such option grants are to be made, the number of shares to be
covered by each such grant, the status of the granted option as either an
Incentive Option or a Non-Statutory Option, the time or times at
   2
which each option is to become exercisable, the vesting schedule (if any)
applicable to the option shares and the maximum term for which the option is to
remain outstanding.

     IV.  STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock. The maximum number of shares of Common
Stock which may be issued over the term of the Plan shall not exceed 1,038,034
shares.

          B.   Shares of Common Stock subject to outstanding options shall be
available for subsequent issuance under the Plan to the extent (i) the options
expire or terminate for any reason prior to exercise in full or (ii) the
options are canceled in accordance with the cancellation-regrant provisions of
Article Two. All shares issued under the Plan, whether or not those shares are
subsequently repurchased by the Corporation pursuant to its repurchase rights
under the Plan, shall reduce on a share-for-share basis the number of shares of
Common Stock available for subsequent issuance under the Plan.

          C.   Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and/or class of securities issuable
under the Plan and (ii) the number and/or class of securities and the exercise
price per share in effect under each outstanding option in order to prevent the
dilution or enlargement of benefits thereunder. The adjustments determined by
the Plan Administrator shall be final, binding and conclusive. In no event
shall any such adjustments be made in connection with the conversion of one or
more outstanding shares of the Corporation's preferred stock into shares of
Common Stock.

                                  ARTICLE TWO

                              OPTION GRANT PROGRAM

     I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
shall comply with the terms specified below. Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   Exercise Price.

               1)   The exercise price per share shall be fixed by the Plan
Administrator in accordance with the following provisions:

                    (i)  The exercise price per share shall not be less than
     eighty-five percent (85%) of the Fair Market Value per share of Common
     Stock on the option grant date.

                    (ii) If the person to whom the option is granted is a 10%
     Stockholder, then the exercise price per share shall not be less than one
     hundred


                                       2
   3

     ten percent (110)% of the Fair Market Value per share of Common Stock on
     the option grant date.

          2)   The exercise price shall become immediately due upon exercise of
the option and shall, subject to the provisions of Section I of Article Three
and the documents evidencing the option, be payable in cash or check made
payable to the Corporation. Should the Common Stock be registered under Section
12(g) of the 1934 Act at the time the option is exercised, then the exercise
price may also be paid as follows:

                    (i)  in shares of Common Stock held for the requisite period
     necessary to avoid a charge to the Corporation's earnings for financial
     reporting purposes and valued at Fair Market Value on the Exercise Date, or

                    (ii) to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to which
     the Optionee shall concurrently provide irrevocable written instructions
     (a) to a Corporation-designated brokerage firm to effect the immediate sale
     of the purchased shares and remit to the Corporation, out of the sale
     proceeds available on the settlement date, sufficient funds to cover the
     aggregate exercise price payable for the purchased shares plus all
     applicable Federal, state and local income and employment taxes required to
     be withheld by the Corporation by reason of such exercise and (b) to the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option grant. However, no option shall have a term in excess of
ten (10) years measured from the option grant date.

          C.   EFFECT OF TERMINATION OF SERVICE. The following provisions shall
govern the exercise of any options held by the Optionee at the time of cessation
of Service or death:

                    (i)  Should the Optionee cease to remain in Service for any
     reason other than Disability or death, then the Optionee shall have a
     period of three (3) months following the date of such cessation of Service
     during which to exercise each outstanding option held by such Optionee.

                    (ii) Should such Service terminate by reason of Disability,
     then the Optionee shall have a period of six (6) months following the date
     of such cessation of Service during which to exercise each outstanding
     option held by such Optionee. However, should such Disability be deemed to
     constitute Permanent Disability, then the period during which each
     outstanding option held by the Optionee is to remain exercisable shall be
     extended by an additional six (6) months so that the exercise period shall
     be the twelve (12)-month period following the date of the Optionee's
     cessation of Service by reason of such Permanent Disability.

                                       3
   4
                    (iii) Should the Optionee die while holding one or more
     outstanding options, then the personal representative of the Optionee's
     estate or the person or persons to whom the option is transferred pursuant
     to the Optionee's will or in accordance with the laws of descent and
     distribution shall have a period of twelve (12) months following the date
     of the Optionee's death during which to exercise each such option.

                    (iv)  Under no circumstances, however, shall any such
     option be exercisable after the specified expiration of the option term.

                    (v)   During the applicable post-Service exercise period,
     the option may not be exercised in the aggregate for more than the number
     of vested shares for which the option is exercisable on the date of the
     Optionee's cessation of Service. Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term,
     the option shall terminate and cease to be outstanding for any vested
     shares for which the option has not been exercised. However, the option
     shall, immediately upon the Optionee's cessation of Service, terminate and
     cease to be outstanding to the extent it is not exercisable for vested
     shares on the date of such cessation of Service.

          D.   STOCKHOLDER RIGHTS. The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E.   UNVESTED SHARES. The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock under the Plan. Should the Optionee cease Service while holding such
unvested shares, the Corporation shall have the right to repurchase, at the
exercise price paid per share, all or (at the discretion of the Corporation
and with the consent of the Optionee) any of those unvested shares. The terms
upon which such repurchase right shall be exercisable (including the period and
procedure for exercise and the appropriate vesting schedule for the purchased
shares) shall be established by the Plan Administrator and set forth in the
document evidencing such repurchase right. The Plan Administrator may not
impose a vesting schedule upon any option grant or any shares of Common Stock
subject to the option which is more restrictive than twenty percent (20%) per
year vesting, beginning one (1) year after the option grant date. However, this
minimum vesting requirement shall not be applicable with respect to any option
granted to a Highly-Compensated Person. All outstanding repurchase rights under
the Plan shall terminate automatically in the event of any Corporate
Transaction, except to the extent that the repurchase rights are assigned to
the successor corporation (or parent thereof) in connection with such Corporate
Transaction.

          F.   FIRST REFUSAL RIGHTS. Pursuant to Article VIII of the
Corporation's bylaws, the Corporation shall have the right of first refusal
with respect to any proposed disposition by the Optionee (or any successor in
interest) of any shares of Common Stock issued under the Plan. Such right of
first refusal shall lapse upon the registration of the shares of Common Stock
under Section 12(g) of the 1934 Act.

          G.   LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of the
Optionee, the option shall be exercisable only by the Optionee and shall not be
assignable or transferable other than by will or the laws of descent and
distribution following the Optionee's death. However, a Non-Statutory Option may
be assigned in accordance with the terms of a Qualified Domestic Relations
Order. The assigned option may only be exercised by the person or persons

                                       4
   5
who acquire a proprietary interest in the option pursuant to such Qualified
Domestic Relations Order. The terms applicable to the assigned option (or
portion thereof) shall be the same as those in effect for the option
immediately prior to such assignment and shall be set forth in such documents
issued to the assignee as the Plan Administrator may deem appropriate.

          H.   WITHHOLDING. The Corporation's obligation to deliver shares of
Common stock upon the exercise of any options granted under the Plan shall be
subject to the satisfaction of all applicable Federal, state and local income
and employment tax withholding requirements.

     II.  INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options. Except as modified by the provisions of this Section II, all the
provisions of the Plan shall be applicable to Incentive Options. Options which
are specifically designated as Non-Statutory Options shall not be subject to
the terms specified in this Section II.

          A.   ELIGIBILITY. Incentive Options may only be granted to Employees.

          B.   EXERCISE PRICE. The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

          C.   DOLLAR LIMITATION. The aggregate Fair Market Value of the shares
of Common stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one (1) calendar year
shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

          D.   10% STOCKHOLDER. If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the option term shall not exceed five (5)
years measured from the option grant date.

     III. CORPORATE TRANSACTION

          A.   In the event of any Corporate Transaction, each outstanding
option shall terminate and cease to be outstanding, except to the extent
assumed by the successor corporation (or parent thereof) in connection with
such Corporate Transaction.

          B.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in the consummation of such Corporate
Transaction, had the option been exercised immediately prior to such Corporate
Transaction. Appropriate adjustments shall also be made to (i) the number and
class of securities available for issuance under the Plan following the
consummation of such Corporate Transaction and (ii) the exercise price payable
per share under each outstanding option, provided the aggregate exercise price
payable for such securities shall remain the same.


                                       5
   6
     C. The grant of options under the Plan shall in no way affect the right of
the Corporation to adjust, reclassify, reorganize or otherwise change its
capital or business structure or to merge, consolidate, dissolve, liquidate or
sell or transfer all or any part of its business or assets.

IV.  CANCELLATION AND REGRANT OF OPTIONS

     The Plan administrator shall have the authority to effect, at any time and
from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Plan and to grant in
substitution therefor new options covering the same of different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                                 ARTICLE THREE

                                 MISCELLANEOUS

I.  FINANCING

     The Plan Administrator may permit any Optionee to pay the option exercise
price by delivering a promissory note payable in one or more installments. The
terms of any such promissory note (including the interest rate and the terms of
repayment) shall be established by the Plan Administrator in its sole
discretion. Promissory notes may be authorized with or without security or
collateral. In all events, the maximum credit available to each Optionee may
not exceed the sum of (i) the aggregate option exercise price payable for the
purchased shares (less the par value of such shares) plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee in
connection with the option exercise.

II.  ADDITIONAL AUTHORITY

     A.  The Plan Administrator shall have the discretion, exercisable either
at the time an option is granted or at any time while the option remains
outstanding:

         (i) to extend the period of time for which the option is to remain
exercisable following the Optionee's cessation of Service or death from the
limited period otherwise in effect for that option to such greater period of
time as the Plan Administrator shall deem appropriate; provided, that is no
event shall such option be exercisable after the specified expiration of the
option term, and/or

        (ii) to permit the option to be exercised, during the applicable
post-Service exercise period, not only with respect to the number of vested
shares of Common Stock for which such option is exercisable at the time of the
Optionee's cessation of Service or death but also with respect to one or more
additional installments in which the Optionee would have vested under the option
had the Optionee continued in Service.

of the ten (10)-year period measured from the date the Plan is adopted by the
Board, (ii) the date on which all shares available for issuance under the Plan

     IV. AMENDMENT OF THE PLAN

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects. However, no such amendment
or modification shall, without the consent of the Optionees, adversely affect

increase the maximum number of shares issuable under the Plan, except for
permissible adjustments in the event of certain changes in the Corporation's
capitalization, (ii) materially modify the eligibility requirements for Plan
participation or (iii) materially increase the benefits accruing to Plan
participants.

          B.   Options may be granted under the Plan to purchase shares of
Common Stock in excess of the number of shares then available for issuance under
the Plan, provided any such options actually granted may not be exercised until
there is obtained stockholder approval of an amendment sufficiently increasing
the number of shares of Common Stock available for issuance under the Plan. If
such stockholder approval is not obtained within twelve (12) months after the
date the excess grants are first made, then any options granted on the basis of
such excess shares shall terminate and cease to be outstanding.

required by regulatory authorities having jurisdiction over the Plan, the
options granted under it and the shares of Common Stock issued pursuant to it.

     VII. NO EMPLOYMENT OR SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee any right to
continue in Service for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Corporation (or any Parent or
Subsidiary employing or retaining Optionee) or of the Optionee, which rights are
hereby expressly reserved by each, to terminate the Optionee's Service at any
time for any reason, with or without cause.

RECITALS

        A. The Board has adopted the Plan for the purpose of retaining the
services of selected Employees, non-employee members of the Board or the board
of directors of any Parent or Subsidiary and consultants who provide services to
the Corporation (or any Parent or Subsidiary).

        B. Optionee is to render valuable services to the Corporation (or a
Parent or Subsidiary), and this Agreement is executed pursuant to, and is
intended to carry out the purposes of, the Plan in connection with the
Corporation's grant of an option to Optionee.

        C. All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix.

            NOW, THEREFORE, it is hereby agreed as follows:

            1. GRANT OF OPTION. The Corporation hereby grants to Optionee, as of
the Grant Date, an option to purchase up to the number of Option Shares
specified in the Grant Notice. The Option Shares shall be purchasable from time
to time during the option term specified in Paragraph 2 at the Exercise Price.

            2. OPTION TERM. This option shall have a term of ten (10) years
measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5, 6 or 17.

            3 LIMITED TRANSFERABILITY. This option shall be neither transferable
nor assignable by Optionee other than by will or by the laws of descent and
distribution following Option's death and may be exercised, during Option's
lifetime, only by Optionee. However, if this option is designated a
Non-Statutory Option in the Grant Notice, then this option may also be assigned
in accordance with the terms of a Qualified Domestic Relations Order. If so
assigned, the assigned option shall be exercisable only by the person or persons
who acquire a proprietary interest in the option pursuant to such Qualified
Domestic Relations Order. The terms applicable to the assigned option (or
portion thereof) shall be the same as those in effect for this option
immediately prior to such assignment and shall be set forth in such documents
issued to the assignee as the Plan Administrator may deem appropriate.

            4, DATES OF EXERCISE. This option shall become exercisable for the
Option Shares in one or more installments as specified in the Grant Notice. As
the option becomes exercisable for such installments, those installments shall
accumulate and the option shall remain exercisable for the accumulated
installments until the Expiration Date or sooner termination of the option term
under Paragraph 5, 6 or 17.


   13

            5. Cessation of Service. The option term specified in Paragraph 2
shall terminate (and this option shall cease to be outstanding) prior to the
Expiration Date should any of the following provisions become applicable.

               (a) Should Optionee cease to remain in Service for any reason
(other than death or Disability) while this option is outstanding, then Optionee
shall have a period of three (3) months (commencing with the date of such
cessation of Service) during which to exercise this option, but in no event
shall this option be exercisable at any time after the Expiration Date.

               (b) Should Optionee die while this option is outstanding, then
the personal representative of Optionee's estate or the person or persons to
whom the option is transferred pursuant to Optionee's will or in accordance with
the laws of descent and distribution shall have the right to exercise this
option. Such right shall lapse and this option shall cease to be outstanding
upon the earlier of (i) the expiration of the twelve (12)-month period measured
from the date of Optionee's death or (ii) the Expiration Date.

               (c) Should Optionee cease Service by reason of Disability while
this option is outstanding, then Optionee shall have a period of six (6) months
(commencing with the date of such cessation of Service) during which to exercise
this option. However, should such Disability be deemed to constitute Permanent
Disability, then the period during which this option is to remain exercisable
shall be extended by an additional six (6) months so that the exercise period
shall be the twelve (12)-month period following the date of Optionee's cessation
of Service by reason of such Permanent Disability. In no event shall this option
be exercisable at any time after the Expiration Date.

               Note: Exercise of this option on a date later than three (3)
               months following cessation of Service due to Disability will
               result in loss of favorable Incentive Option treatment, unless
               such Disability constitutes Permanent Disability. In the event
               that Incentive Option treatment is not available, this option
               will be taxed as a Non-Statutory Option upon exercise.

               (d) During the limited period of post-Service exercisability,
this option may not be exercised in the aggregate for more than the number of
vested Option Shares for which the option is exercisable at the time of
Optionee's cessation of Service. Upon the expiration of such limited exercise
period or (if earlier) upon the Expiration Date, this option shall terminate and
cease to be outstanding for any vested Option Shares for which the option has
not been exercised. To the extent Optionee is not vested in the Option Shares at
the time of Optionee's cessation of Service, this option shall immediately
terminate and cease to be outstanding with respect to those shares.

            6. SPECIAL TERMINATION OF OPTION

               (a) in the event of a Corporate Transaction, this option shall
terminate and cease to be outstanding, except to the extent assumed by the
successor corporation or parent thereof In connection with such Corporate
Transaction.

               (b) If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Exercise
Price, provided the aggregate Exercise Price shall remain the same.

               (c) This Agreement shall not in any way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

            7. ADJUSTMENT IN OPTION SHARES. Should any change be made to the
Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be made to (i) the total number
and/or class of securities subject to this option and (ii) the Exercise Price in
order to reflect such change and thereby preclude a dilution or enlargement of
benefits hereunder.

            8. STOCKHOLDER RIGHTS. The holder of this option shall not have any
stockholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become a holder of record
of the purchased shares,

            9. MANNER OF EXERCISING OPTION

               (a) In order to exercise this option with respect to all or any

                  Should the Common Stock be registered under Section 12(g) of
            the 1934 Act at the time the option is exercised, then the Exercise
            Price may also be paid as follows:

            other person or persons exercising the option) for the requisite
            period necessary to avoid a charge to the Corporation's earnings for
            financial reporting purposes and valued at fair Market Value on the
            Exercise Date; or

                        (D) to the extent the option is exercised for vested
            Option Shares, through a special sale and remittance procedure
            pursuant to which Optionee (or any other person or persons
            exercising the option) shall concurrently provide irrevocable
            written instructions (a) to a Corporation designated brokerage firm
            to effect the immediate sale of the purchased shares and remit to
            the Corporation, out of the sale proceeds available on the
            settlement date, sufficient funds to cover the aggregate Exercise
            Price payable for the purchased shares plus all applicable Federal,
            state and local income and employment taxes required to be withheld
            by the Corporation by reason of such exercise and (b) to the
            Corporation to deliver the certificates for the purchased shares
            directly to such brokerage firm in order to complete the sale.

                   Except to the extent the sale and remittance procedure is
             utilized in connection with the option exercise, payment of the
             Exercise Price must accompany the Purchase Agreement delivered to
             the Corporation in connection with the option exercise.

                             (iii) Furnish to the Corporation appropriate

Optionee ceases to be an Employee for any reason other than death or Permanent
Disability or (ii) more than twelve (12) months after the date Optionee ceases
to be an Employee by reason of Permanent Disability,

                 (b) This option shall not become exercisable in the calendar
year in which granted if (and to the extent) the aggregate Fair Market Value
(determined at the Grant Date) of the Common Stock for which this option would
otherwise first become exercisable in such calendar year would, when added to

option is deferred by reason of the foregoing limitation, the deferred portion
shall become exercisable in the first calendar year or years thereafter in which
the One Hundred Thousand Dollar ($100,000) limitation of this Paragraph 18(b)
would not be contravened, but such deferral shall in all events end immediately
prior to the effective date of a Corporate Transaction in which this option is
not to be assumed, whereupon the option shall become immediately exercisable as
a Non-Statutory Option for the deferred portion of the Option Shares.

                 (c) Should Optionee hold, in addition to this option, one or
more other options to purchase Common Stock which become exercisable for the

            AGREEMENT made as of this ___________ day of Corporation, a Delaware
corporation (the "Corporation"), _______ , 19___, by and among Quintus an
Optionee under the Corporation's 1995 Stock Option Plan (the "Plan"), and
Optionee's spouse.

            All capitalized terms in this Agreement shall have the meaning
assigned to them in this Agreement or in the attached Appendix.

        A.  EXERCISE OF OPTION

            1. EXERCISE. Optionee hereby purchases shares of Common Stock (the
"Purchased Shares") pursuant to that certain option (the "Option") granted
Optionee on _______ , 199_ (the "Grant Date") to purchase up to _______ shares
of Common Stock under the Plan at the exercise price of $________ per share (the

Corporation, Optionee shall pay the Exercise Price for the Purchased Shares in
accordance with the provisions of the Option Agreement and shall deliver
whatever additional documents may be required by the Option Agreement as a
condition for exercise, together with a duly-executed blank Assignment Separate

confirms that Optionee has been informed that the Purchased Shares are
restricted securities under the 1933 Act and may not be resold or transferred
unless the Purchased Shares are first registered under the Federal securities
laws or unless an exemption from such registration is available. Accordingly,
Optionee hereby acknowledges that Optionee is prepared to hold the Purchased
Shares for an indefinite period and that Optionee is aware that SEC Rule 144
issued under the 1933 Act which exempts certain resales of unrestricted

is not presently available to exempt the resale of the Purchased Shares from the
registration requirements of the 1933 Act.

            2. RESTRICTIONS ON DISPOSITION OF PURCHASED SHARES. Optionee shall
make no disposition of the Purchased Shares (other than a Permitted Transfer)
unless and until there is compliance with all of the following requirements:

                      (i) Optionee shall have provided the Corporation with a
        written summary of the terms and conditions of the proposed disposition.

                      (ii) Optionee shall have complied with all requirements of
        this Agreement applicable to the disposition of the Purchased Shares.

                      (iii) Optionee shall have provided the Corporation with
        written assurances, in form and substance satisfactory to the
        Corporation, that (a) the proposed disposition does not require
        registration of the Purchased Shares under the 1933 Act or (b) all
        appropriate action necessary for compliance with the registration
        requirements of the 1933 Act or any exemption from registration
        available under the 1933 Act (including Rule 144) has been taken.

                      (iv) Optionee shall have provided the Corporation with
        written assurances, in form and substance satisfactory to the
        Corporation, that the proposed disposition shall not result in the
        contravention of any transfer restrictions applicable to the Purchased
        Shares pursuant to the provisions of state securities laws.

             The Corporation shall not be required (i) to transfer on its books
any Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement or (ii) to treat as the owner of the Purchased
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.

             3. RESTRICTIVE LEGENDS. The stock certificates for the Purchased
Shares shall be endorsed with one or more restrictive legends, including the
following:

                      (i) "The shares represented by this certificate have not
        been registered under the Securities Act of 1933. The shares may not be
        sold or offered for sale in the absence of (a) an effective registration
        statement for the shares under such Act, (b) a 'no action' letter of the
        Securities and Exchange Commission with respect to such sale or offer or
        (c) satisfactory assurances to the Corporation that registration under
        such Act is not required with respect to such sale or offer."

                      (ii) "The shares represented by this certificate are
        subject to certain repurchase rights and rights of first refusal granted
        to the Corporation and accordingly may not be sold, assigned,
        transferred, encumbered or in any manner disposed of except in
        conformity with the terms of a written agreement dated


                                       2
   23

        _______ 199__ between the Corporation and the registered holder of the
        shares (or the predecessor in interest to the shares). A copy of such
        agreement is maintained at the Corporation's principal corporate
        offices."

        C. TRANSFER RESTRICTIONS

            1. RESTRICTION on TRANSFER. Except for any Permitted Transfer,
Optionee shall not transfer, assign, encumber or otherwise dispose of any of the
Purchased Shares which are subject to the Repurchase Right. In addition,
Purchased Shares which are released from the Repurchase Right shall not be
transferred, assigned, encumbered or otherwise disposed of in contravention of
the First Refusal Right, the Market Stand-Off or the Special Purchase Right.

            2. TRANSFEREE OBLIGATIONS. Each person (other than the Corporation)
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to (i) the Repurchase
Right, (ii) the First Refusal Right and (iii) the Market Stand-Off, to the same
extent such shares would be so subject if retained by Optionee.

            3. MARKET STAND-OFF.

               (a) In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporation's initial public
offering, Owner shall not sell, make any short sale of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to, any Purchased Shares without the prior written consent of the
Corporation or its underwriters. Such restriction (the "Market Stand-Off") shall
be in effect for such period of time from and after the effective date of the
final prospectus for the offering as may be requested by the Corporation or such
underwriters. In no event, however, shall such period exceed one hundred eighty
(180) days, and the Market Stand-Off shall in all events terminate two (2) years
after the effective date of the Corporation's initial public offering.

               (b) Owner shall be subject to the Market Stand-Off provided and
only if the officers and directors of the Corporation are also subject to
similar restrictions.

               (C) Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

               (d) In order to enforce the Market Stand-Off, the Corporation may
impose stop-transfer instructions with respect to the Purchased Shares until the
end of the applicable stand-off period.

        D. REPURCHASE RIGHT

            1. GRANT. The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the 90 day period following
the date Optionee ceases for any reason to remain in Service or (if later)
during the 90 day period following the execution date of this Agreement, to
repurchase at the Exercise Price all or (at the discretion of the Corporation
and with the consent of Optionee) any portion of the Purchased Shares in which
Optionee is not, at the time of his or her cessation of Service, vested in
accordance with the Vesting Schedule (such shares to be hereinafter referred to
as the "Unvested Shares").

            2. EXERCISE OF THE REPURCHASE RIGHT. The Right of Repurchase shall
be exercisable only by written notice delivered to the Owner which sets forth
the date on which the repurchase is to be effected. Such date of repurchase
shall be prior to the applicable 90 day period specified in paragraph D.1
above. The Corporation shall, prior to the close of business on the date
specified for the repurchase, pay to the Owner an amount equal to the Exercise
Price previously paid for the Unvested Shares which are to be repurchased from
Owner. Payment shall be made in cash or cash equivalents or by canceling
indebtedness to the Corporation incurred by the Owner in the purchase of the
Purchased Shares. The Owner shall deliver to the Corporation the certificate(s)
representing the Purchased Shares to be repurchased, properly endorsed for
transfer, promptly following receipt of the written notice specified above.

            3. TERMINATION OF THE REPURCHASE RIGHT. The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph D.2. In addition, the Repurchase Right shall terminate
and cease to be exercisable with respect to any and all Purchased Shares in
which Optionee vests in accordance with the Vesting Schedule. All Purchased
Shares as to which the Repurchase Right lapses shall, however, remain subject to
(i) the First Refusal Right, (ii) the Market Stand-Off and (iii) the Special
Purchase Right.

            4. AGGREGATE VESTING LIMITATION. If the Option is exercised in more
than one increment so that Optionee is a party to one or more other Stock
Purchase Agreements (the "Prior Purchase Agreements") which are executed prior
to the date of this Agreement, then the total number of Purchased Shares as to
which Optionee shall be deemed to have a fully-vested interest under this
Agreement and all Prior Purchase Agreements shall not exceed in the aggregate
the number of Purchased Shares in which Optionee would otherwise at the time be
vested, in accordance with the Vesting Schedule, had all the Purchased Shares
(including those acquired under the Prior Purchase Agreements) been acquired
exclusively under this Agreement.

            5. RECAPITALIZATION. Any new, substituted or additional securities
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right, but only
to the extent the Purchased Shares are at the time covered by such right.
Appropriate adjustments to reflect such distribution shall be made to the number
and/or class of Purchased Shares subject to this Agreement and to the price per
share to be paid upon the exercise of the Repurchase Right in order to reflect
the effect of any such Recapitalization upon



                                       4
   25

the Corporation's capital structure; provided, however, that the aggregate
purchase price shall remain the same.

            6. CORPORATE TRANSACTION.

               (a) Immediately prior to the consummation of any Corporate
Transaction, the Repurchase Right shall automatically lapse in its entirety,
except to the extent the Repurchase Right is to be assigned to the successor
corporation (or parent thereof) in connection with the Corporate Transaction.

               (b) To the extent the Repurchase Right remains in effect
following a Corporate Transaction, such right shall apply to the new capital
stock or other property (including any cash payment) received in exchange for
the Purchased Shares in consummation of the Corporate Transaction, but only to
the extent the Purchased Shares are at the time covered by such right.
Appropriate adjustments shall be made to the price per share payable upon
exercise of the Repurchase Right to reflect the effect of the Corporate
Transaction upon the Corporation's capital structure; provided, however, that
the aggregate purchase price shall remain the same.

        E.  RIGHT OF FIRST REFUSAL

            Pursuant to Article VIII of the Corporation's bylaws, the
Corporation shall have the right of first refusal (the "First Refusal Right"),
exercisable in connection with any proposed transfer of the Purchased Shares in
which Optionee has vested in accordance with the Vesting Schedule. The First
Refusal Right shall lapse upon the registration of the Common Stock under
Section 12(g) of the 1934 Act.

        F.  MARITAL DISSOLUTION OR LEGAL SEPARATION

            1. GRANT. In connection with the dissolution of Optionee's marriage
or the legal separation of Optionee and Optionee's spouse, the Corporation shall
have the right (the "Special Purchase Right") to purchase from Optionee's
spouse, in accordance with the provisions of Paragraph F.3, all or any portion
of the Purchased Shares which would otherwise be awarded to such spouse in
settlement of any community property or other marital property rights such
spouse may have in such shares.

            2. NOTICE OF DECREE OR AGREEMENT. Optionee shall promptly provide
the Corporation with written notice (the "Dissolution Notice") of (i) the entry
of any judicial decree or order resolving the property rights of Optionee and
Optionee's spouse in connection with their marital dissolution or legal
separation or (ii) the execution of any contract or agreement relating to the
distribution or division of such property rights. The Dissolution Notice shall
be accompanied by a copy of the actual decree or order of dissolution or
contract or agreement between Optionee and Optionee's spouse which provides for
the award to the spouse of one or more Purchased Shares in settlement of any
community property or other marital property rights such spouse may have in such
shares.

            3. EXERCISE OF THE SPECIAL PURCHASE RIGHT. The Special Purchase
Right shall be exercisable by delivery of written notice (the "Purchase Notice")
to Optionee and


                                       5
   26


Optionee's spouse within thirty (30) days after the Corporation's receipt of the
Dissolution Notice. The Purchase Notice shall indicate the number of shares to
be purchased by the Corporation, the date such purchase is to be effected (such
date to be not less than five (5) business days, nor more than ten (10) business
days, after the date of the Purchase Notice) and the Fair Market Value to be
paid for such Purchased Shares. Optionee (or Optionee's spouse, to the extent
such spouse has physical possession of the Purchased Shares) shall, prior to the
close of business on the date specified for the purchase, deliver to the
Corporation the certificates representing the shares to be purchased. The
Corporation shall, concurrently with the receipt of the stock certificates, pay
to Optionee's spouse (in cash or cash equivalents) an amount equal to the Fair
Market Value specified for such shares in the Purchase Notice.

            If Optionee's spouse does not agree with the Fair Market Value
specified for the shares in the Purchase Notice, then the spouse shall promptly
notify the Corporation in writing of such disagreement and the fair market value
of such shares shall thereupon be determined by an appraiser of recognized
standing selected by the Corporation and the spouse. If they cannot agree on an
appraiser within twenty (20) days after the date of the Purchase Notice, each
shall select an appraiser of recognized standing, and the two (2) appraisers
shall designate a third appraiser of recognized standing whose appraisal shall
be determinative of such value. The cost of the appraisal shall be shared
equally by the Corporation and Optionee's spouse. The closing shall then be held
on the fifth (5th) business day following the completion of such appraisal;
provided, however, that if the appraised value is more than twenty-five percent
(25%) greater than the Fair Market Value specified for the shares in the
Purchase Notice, the Corporation shall have the right, exercisable prior to the
expiration of such five (5) business-day period, to rescind the exercise of the
Special Purchase Right and thereby revoke its election to purchase the shares
awarded to the spouse. In the event the Corporation so revokes its election, the
Corporation shall bear the entire cost of the appraisal.

            4. LAPSE. The Special Purchase Right shall lapse upon the earlier to
occur of (i) the lapse of the First Refusal Right or (ii) the expiration of the
exercise period specified in Paragraph F.3, to the extent the Special Purchase
Right is not timely exercised in accordance with such paragraph.

        G.  ESCROW

            1. DEPOSIT. Upon issuance, the certificates for the Purchased Shares
which are subject to the Repurchase Right shall be deposited in escrow with the
Corporation to be held in accordance with the provisions of this Article G. Each
deposited certificate shall be accompanied by a duly-executed Assignment
Separate from Certificate in the form of Exhibit I. The deposited certificates,
together with any other assets or securities from time to time deposited with
the Corporation pursuant to the requirements of this Agreement, shall remain in
escrow until such time or times as the certificates (or other assets and
securities) are to be released or otherwise surrendered for cancellation in
accordance with Paragraph G.3. Upon delivery of the certificates (or other
assets and securities) to the Corporation, Owner shall be issued a receipt
acknowledging the number of Purchased Shares (or other assets and securities)
delivered in escrow.

   27

            2. RECAPITALIZATION/REORGANIZATION. Any new, substituted or
additional securities or other property which is by reason of any
Recapitalization or Reorganization distributed with respect to the Purchased
Shares shall be delivered to the Corporation to be held in escrow under this
Article G, but only to the extent the Purchased Shares are at the time subject
to the escrow requirements hereunder. However, all regular cash dividends on the
Purchased Shares (or other securities at the time held in escrow) shall be paid
directly to Owner and shall not be held in escrow.

            3. RELEASE/SURRENDER. The Purchased Shares, together with any other
assets or securities held in escrow hereunder, shall be subject to the following
terms relating to their release from escrow or their surrender to the
Corporation for repurchase and cancellation:

               (i) Should the Corporation elect to exercise the Repurchase Right
        with respect to any Unvested Shares, then the escrowed certificates for
        those Unvested Shares (together with any other assets or securities
        attributable thereto) shall be surrendered to the Corporation
        concurrently with the payment to Owner of an amount equal to the
        aggregate Exercise Price for such Unvested Shares, and Owner shall cease
        to have any further rights or claims with respect to such Unvested
        Shares (or other assets or securities attributable thereto).

               (ii) Should the Corporation elect to exercise the First Refusal
        Right with respect to any Target Shares held at the time in escrow
        hereunder, then the escrowed certificates for those Target Shares
        (together with any other assets or securities attributable thereto)
        shall be surrendered to the Corporation concurrently with the payment of
        the Paragraph E.3 purchase price for such Target Shares to Owner, and
        Owner shall cease to have any further rights or claims with respect to
        such Target Shares (or other assets or securities attributable thereto).

               (iii) Should the Corporation elect not to exercise the Repurchase
        Right with respect to any Unvested Shares or the First Refusal Right
        with respect to any Target Shares held at the time in escrow hereunder,
        then the escrowed certificates for those shares (together with any other
        assets or securities attributable thereto) shall be released to Owner.

               (iv) As the Purchased Shares (or any other assets or securities
        attributable thereto) vest in accordance with the Vesting Schedule, the
        certificates for those vested shares (as well as all other vested assets
        and securities) shall be released from escrow upon Owner's request, but
        not more frequently than once every six (6) months.

               (v) All Purchased Shares which vest (and any other vested assets
        and securities attributable thereto) shall be released within thirty
        (30) days after the earlier to occur of (a) Optionee's cessation of
        Service or (b) the lapse of the First Refusal Right.


                                       7
   28

               (vi) All Purchased Shares (or other assets or securities)
        released from escrow shall nevertheless remain subject to (a) the First
        Refusal Right, to the extent such right has not otherwise lapsed, (b)
        the Market Stand-Off, until such restriction terminates, and (c) the
        Special Purchase Right, to the extent such right has not otherwise
        lapsed.

        H.  SPECIAL TAX ELECTION

            The acquisition of the Purchased Shares may result in adverse tax
consequences which may be avoided by FILING an election under Code Section
83(b). Such election must be filed within thirty (30) days after the date of
this Agreement. A description of the tax consequences applicable to the
acquisition of the Purchased Shares and the form for making the Code Section
83(b) election are set forth in Exhibit II. OPTIONEE SHOULD CONSULT WITH HIS OR
HER TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES OF ACQUIRING THE PURCHASED
SHARES AND THE ADVANTAGES AND DISADVANTAGES OF FILING THE CODE SECTION 83(b)
ELECTION. OPTIONEE ACKNOWLEDGES THAT IT IS OPTION'S SOLE RESPONSIBILITY, AND NOT
THE CORPORATION'S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(b), EVEN IF
OPTIONEE REQUESTS THE CORPORATION OR ITS REPRESENTATIVES TO MAKE THIS FILING ON
HIS OR HER BEHALF.

        I.  GENERAL PROVISIONS

            1. ASSIGNMENT The Corporation may assign the Repurchase Right, the
First Refusal Right and/or the Special Purchase Right to any person or entity
selected by the Board, including (without limitation) one or more stockholders
of the Corporation.

            2. NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this Agreement or
in the Plan shall confer upon Optionee any right to continue in Service for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Parent or Subsidiary employing or
retaining Optionee) or of Optionee, which rights are hereby expressly reserved
by each, to terminate Optionee's Service at any time for any reason, with or
without cause.

            3. NOTICES. Any notice required to be given under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or upon
deposit in the U.S. mail, registered or certified, postage prepaid and properly
addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

            4. NO WAIVER. The failure of the Corporation in any instance to
exercise the Repurchase Right, the First Refusal Right or the Special Purchase
Right shall not constitute a waiver of any other repurchase rights and/or rights
of first refusal that may subsequently arise under the provisions of this
Agreement or any other agreement between the Corporation and Optionee or
Optionee's spouse. No waiver of any breach or condition of this Agreement shall
be


                                       8
   29

deemed to be a waiver of any other or subsequent breach or condition, whether of
like or different nature.

            5. CANCELLATION OF SHARES. If the Corporation shall make available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement). Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

        J.  MISCELLANEOUS PROVISIONS

            1. OPTIONEE UNDERTAKING. Optionee hereby agrees to take whatever
additional action and execute whatever additional documents the Corporation may
deem necessary or advisable in order to carry out or effect one or more of the
obligations or restrictions imposed on either Optionee or the Purchased Shares
pursuant to the provisions of this Agreement.

            2. AGREEMENT IS ENTIRE CONTRACT. This Agreement constitutes the
entire contract between the parties hereto with regard to the subject matter
hereof. This Agreement is made pursuant to the provisions of the Plan and shall
in all respects be construed in conformity with the terms of the Plan.

            3. GOVERNING LAW. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of California without resort to that
State's conflict-of-laws rules.

            4. COUNTERPARTS. This Agreement may be executed in counterparts,
each of which shall be deemed to be an original, but all of which together shall
constitute one and the same instrument.

            5. SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall
inure to the benefit of, and be binding upon, the Corporation and its successors
and assigns and upon Optionee, Optionee's assigns and the legal representatives,
heirs and legatees of Optionee's estate, whether or not any such person shall
have become a party to this Agreement and have agreed in writing to join herein
and be bound by the terms hereof.

            6. POWER OF ATTORNEY. Optionee's spouse hereby appoints Optionee his
or her true and lawful attorney in fact, for him or her and in his or her name,
place and stead, and for his or her use and benefit, to agree to any amendment
or modification of this Agreement and to execute such further instruments and
take such further actions as may reasonably be necessary to carry out the intent
of this Agreement. Optionee's spouse further gives and grants unto Optionee as
his or her attorney in fact full power and authority to do and perform every act
necessary and


                                       9
   30

proper to be done in the exercise of any of the foregoing powers as fully as he
or she might or could do if personally present, with full power of substitution
and revocation, hereby ratifying and confirming all that Optionee shall lawfully
do and cause to be done by virtue of this power of attorney.
