                               ALLAIRE CORPORATION

                            1998 STOCK INCENTIVE PLAN
                  NONSTATUTORY EMPLOYEE STOCK OPTION AGREEMENT

     This is a NONSTATUTORY EMPLOYEE STOCK OPTION AGREEMENT between Allaire
Corporation, a Delaware corporation (the "Company"), and the optionee (the
"Optionee") identified on the Notice of Grant of Stock Options to which this
Agreement is attached and which is incorporated into this Agreement by reference
(the "Notice").

     WHEREAS, the Company desires to carry out the purposes of the Allaire
Corporation 1998 Stock Incentive Plan (the "Plan") by affording the Optionee an
opportunity to purchase shares of Common Stock of the Company, par value $.01
per share ("Common Stock"), according to the terms set forth herein.

     NOW THEREFORE, the parties hereto hereby agree as follows:

          1.  GRANT OF OPTION. Subject to the terms of the Plan, the Company
hereby grants to the Optionee the right and option (the "Option") to purchase
the number of shares of the Company's Common Stock specified in the Notice (the
"Shares") on the terms and conditions hereinafter set forth.

          2.  PURCHASE PRICE. The purchase price of each of the Shares subject
to the Option shall be the exercise price per share specified in the Notice,
which price has been specified in accordance with Section 5(a) of the Plan.

          3.  OPTION PERIOD.

             (a) Subject to the provisions of Sections 5 and 6 of this
     Agreement, the Option shall become exercisable as to the number of Shares
     and on the dates specified in the exercise schedule in the Notice. The
     exercise schedule shall be cumulative; thus, to the extent the Option has
     not already been exercised and has not expired, terminated or been
     canceled, the Optionee may at any time, and from time to time, purchase all
     or any portion of the Shares then purchasable under the exercise schedule.

             (b) The Option and all rights to purchase Shares thereunder shall
     cease on the earliest of:

                    (i)    the expiration date specified in the Notice (which
                    date shall not be more than ten years after the date of this
                    Agreement);

                    (ii)   termination of the Optionee's employment for Cause
                    (as defined in the Plan);

                    (iii)  the expiration of the period after the termination of
                    the Optionee's employment, other than a termination for
                    Cause, within which the Option is exercisable as specified
                    in Section 5(a) or 5(b) of this Agreement, whichever is
                    applicable; or

                    (iv) the date, if any, fixed for cancellation pursuant to
                    Section 6(b)(iii) of this Agreement.

Notwithstanding any other provision in this Agreement, in no event may anyone
exercise the Option, in whole or in part, after its original expiration date.

          4.  MANNER OF EXERCISING OPTION.

             (a) The Option may be exercised in whole or in part, by delivering
     written notice of exercise to the Company, specifying the number of shares
     to be purchased. Payment of the purchase price may be made by one or more
     of the following methods:

               (i)    in cash, by certified or bank check or other
               instrument acceptable to the committee under the Plan (the
               "Committee"); or

               (ii)   in the form of shares of the Company's Common Stock
               that are not then subject to restrictions, if permitted by the
               Committee, in its discretion. Such surrendered shares shall be
               valued at Fair Market Value (as defined in the Plan) on the
               exercise date; or

               (iii)  by the Optionee delivering to the Company a properly
               executed exercise notice together with irrevocable instructions
               to a broker to promptly deliver to the Company cash or a check
               payable and acceptable to the Company to pay the purchase price;
               provided that in the event the Optionee chooses to pay the
               purchase price as so provided, the Optionee and the broker shall
               comply with such procedures and enter into such agreements of
               indemnity and other agreements as the Committee shall prescribe
               as a condition of such payment procedure. The Company need not
               act upon such exercise notice until the Company receives full
               payment of the exercise price; or

               (iv)   by any other means, (including, without limitation,
               by delivery of a promissory note of the Optionee, payable on such
               terms as specified by the Committee) which the Committee
               determines are consistent with the purpose of the Plan and with
               applicable laws and regulations.

             (b) The delivery of  certificates  representing  shares of the
     Company's Common Stock to be purchased pursuant to the exercise of the
     Option will be contingent upon receipt by the Company of the full purchase
     price for such shares from the Optionee or the Optionee's legal
     representative, heirs or legatees and the fulfillment of any other
     requirements contained in the Plan or imposed by applicable law.

          5.  EXERCISABILITY OF OPTION AFTER TERMINATION OF EMPLOYMENT.

             (a) During the lifetime of the Optionee, the Option may be
     exercised only while the Optionee is employed by the Company or a parent or
     subsidiary thereof, and only if the Optionee has been continuously so
     employed since the date of this Agreement, except that:

               (i)    the Option shall continue to be exercisable for three
               months after termination of the Optionee's employment, unless the
               Optionee's employment was terminated for Cause, but only to the
               extent that the Option was exercisable immediately prior to the
               Optionee's termination of employment;

               (ii)   in the event the Optionee's employment terminates due to
               Disability, the Optionee or his or her legal representative may
               exercise the Option within one year after the termination of the
               Optionee's employment;

               (iii)  in the event the Optionee's employment terminates due to
               Normal Retirement, the Option shall continue to be exercisable
               for three months after the date of such Normal Retirement; and

               (iv)   if the Optionee's employment terminates after the
               Committee notifies the Optionee pursuant to Section 6(b)(iii) of
               this Agreement that the Option shall be canceled, the Optionee
               may exercise the Option at any time permitted by Section
               6(b)(iii).

             (b) In the event of the Optionee's death prior to expiration of
     the Option, the legal representative, heirs or legatees of the Optionee's
     estate or the personal who acquired the right to exercise the Option by
     bequest or inheritance may exercise the Option within five years after the
     death of the Optionee.

                                       2

             (c) Neither the transfer of the Optionee between any combination
     of the Company, its parent and any subsidiary of the Company, nor a leave
     of absence granted to the Optionee and approved by the Committee, shall be
     deemed a termination of employment. The terms "parent" and "subsidiary" as
     used herein shall have the meaning ascribed to "parent corporation" and
     "subsidiary corporation," respectively in Sections 424(e) and (f) (or
     successor provisions) of the Internal Revenue Code of 1986, as amended.

          6.  ACCELERATION OF OPTION.

             (a)  DEATH, DISABILITY OR RETIREMENT. If any of Sections
     (5)(a)(ii), 5(a)(iii) or 5(b) of this Agreement is applicable, the Option,
     whether or not previously exercisable, shall become immediately exercisable
     in full if the Optionee shall have been employed continuously by the
     Company or a parent or subsidiary thereof between the date the Option was
     granted and the date of such Disability or Normal Retirement or, in the
     event of death, a date not more than three months prior to such death.

             (b)  CHANGE OF CONTROL. In the event of a Change of Control
     (as defined in the Plan):

               (i)    SUBSTITUTE OPTIONS. Subject to the provisions of clause
               (iii) below, after the effective date of such Change of Control,
               the Optionee shall be entitled, upon exercise of the Option, to
               receive, in lieu of shares of the Company's Common Stock (or
               consideration based upon the Fair Market Value of the Company's
               Common Stock), shares of such stock or other securities, cash or
               property (or consideration based upon shares of such stock or
               other securities, cash or property) as the holders of shares of
               the Company's Common Stock received in connection with the Change
               of Control.

               (ii)    PARTIAL ACCELERATION. Notwithstanding any other
               provision of this Section 6, fifty-percent (50%) of the Shares
               which are not then exercisable shall become exercisable upon the
               occurrence of a Change of Control if the Optionee is an employee
               of the Company immediately before the occurrence of the Change of
               Control and (1) the Optionee's employment with the Company is
               terminated by the Company (including any successor or parent
               resulting from the Change in Control) without Cause within six
               (6) months after the Change in Control, or (2) the Company (or
               successor) does not offer the Optionee a Comparable Position upon
               the Change in Control, or (3), if the Optionee is offered and
               accepts a Comparable Position, the Optionee is involuntarily
               removed from such position within six (6) months after the Change
               in Control. For the purpose of this Section 6(b), the term
               "Comparable Position" shall mean a position of employment with
               the Company or its successor following a Change of Control (or if
               the Company or its successor has a Parent following a Change of
               Control, its Parent) (X) with substantially the same or superior
               title, responsibilities, base salary, opportunity for incentive
               compensation, and eligibility for stock options or other equity
               incentives as the Optionee had prior to the Change of Control,
               and (Y) at a location within 50 miles of the Optionee's location
               prior to the Change of Control, without the Optionee's express
               prior written consent. For the purpose of this Section 6(b) the
               term "Cause" shall mean (A) substantial failure by or refusal of
               the Optionee to perform the Optionee's duties to the Company,
               gross neglect of such duties, or other material breach of the
               Optionee's written or oral employment agreement with the Company,
               as the case may be; (B) material misappropriation by the Optionee
               of the Company's property or trade secrets, commission of a
               felony by the Optionee or other public misconduct by the Optionee
               detrimental to the reputation of the Company or (C) material
               dishonesty or material violation of any fiduciary duty or duty of
               loyalty owed by the Optionee to the Company

               (iii)   ACCELERATION OF VESTING AND NOTICE OF CANCELLATION. The
               Committee may cancel the Option as of the effective date of any
               such Change of Control provided that (x) all Shares that have not
               yet become exercisable shall become exercisable in full
               immediately prior to

                                       3
<PAGE>   4
               such Change of Control, (y) notice of such cancellation shall be
               given to the Optionee and (z) the Optionee shall have the right
               to exercise the Option, including exercising Shares that became
               exercisable pursuant to the acceleration provisions o f clause
               (x) above.

             (c)  EARLY EXERCISE FOR RESTRICTED SHARES. The Optionee may
     exercise the Option in accordance with this Section 6(c) for shares of the
     Company's Common Stock prior to the date or dates upon which such shares
     become exercisable under Section 3(a), and the exercise schedule in the
     Notice shall be deemed to have been accelerated for such purpose. The
     shares issued upon such early exercise shall be subject to the restrictions
     set forth in this subsection, and are referred to in this subsection as the
     "Restricted Shares."

               (i)    REVERSE VESTING. Restricted Shares purchased under this
               Section 6(c) prior to the Option becoming exercisable shall
               "vest" according to the same schedule (i.e., on the same dates
               and in the same amounts) as such shares would have become
               purchasable upon exercise of the Option had the exercise schedule
               not been accelerated in accordance with this Section 6(c). In
               addition, Restricted Shares shall be subject to accelerated
               "vesting" as set forth in Section 6(a), Section 6(b)(ii), and
               Section 6(b)(iii) if applicable, to the same extent as the
               exercisability of such shares would have been accelerated had the
               exercise schedule not been previously accelerated in accordance
               with this Section 6(c). Restricted Shares that are not vested
               shall be subject to repurchase by the Company under Sections
               6(c)(ii) and 6(c)(iii) below. As Restricted Shares become vested
               they shall no longer be subject to repurchase by the Company.

               (ii)   COMPANY REPURCHASE RIGHTS. In the event of termination of
               the Optionee's employment by the Company for any reason
               (including death, Disability, Normal Retirement and for Cause),
               the Company shall have the option to purchase all or any part of
               the Restricted Shares that were not vested prior to termination
               of the Optionee's employment (after taking into effect any
               accelerated vesting pursuant to Section 6(a), Section 6(b)(ii)
               and Section 6(b)(iii)) at a per share price equal to the purchase
               paid by the Optionee upon exercise of the Option (subject to
               equitable adjustment for any stock split, stock dividend or
               combination of the Restricted Shares).

               (iii)    TERMS OF COMPANY PURCHASE. If the Company intends to
               repurchase the Restricted Shares subject to repurchase, then it
               shall, within sixty (60) days after termination of the Optionee's
               employment, mail written notice of its intent to repurchase the
               Restricted Shares and the number of Restricted Shares to be
               repurchased to the Optionee's last known address appearing in the
               personnel records of the Company. If the Company has not mailed
               notice within that period, the Restricted Shares will no longer
               be subject to repurchase by the Company. Upon receipt from the
               Optionee of the certificate for the Restricted Shares, duly
               endorsed in blank or accompanied by a duly endorsed blank stock
               power suitable for transferring the Shares to the Company, the
               Company shall send to the Optionee (or his or her heir legatee,
               representative or guardian) the purchase price for the Restricted
               Shares and a certificate for the shares which are not subject to
               repurchase or are not being repurchased by the Company. The
               purchase price for the Restricted Shares being repurchased may be
               payable by check, by cancellation of all or a portion of any
               outstanding indebtedness of the Optionee to the Company, or both.
               If the Company has not received the certificate for the
               Restricted Shares by the time the Company is prepared to pay the
               purchased price for such shares, then the Company, at its option,
               may coincident with the payment of the purchase price and/or
               cancellation of debt, make appropriate entries in the records of
               the Company to effect the transfer of the Restricted Shares to
               the Company free and clear of any liens or encumbrances.

               (iv)    OPTIONEE REPRESENTATIONS. By exercising the shares under
               this subsection 6(c), the Optionee represents that (i) he or she
               is acquiring the Restricted Shares for investment and not with a
               view to, or for resale in connection with, any distribution
               thereof; (ii) the Restricted Shares are "restricted securities"
               within the meaning of Rule 144 promulgated under the Securities
               Act of 1933, as amended (the "Securities Act"), and that there is
               no assurance that such Rule will apply to future resales of the
               Restricted Shares; (iii) he or she will make no sale or other
               distribution that would cause the Optionee to be deemed an
               "underwriter" within the meaning of Section 2(11) of the
               Securities Act; and (iv) he or she will make no sale, pledge,
               transfer or other disposition of the Restricted Shares received
               except in accordance with this Agreement unless a registration
               statement with respect to the Restricted Shares is then in effect
               under applicable federal and state securities laws or unless he
               or she obtains an opinion of counsel satisfactory to the Company
               that such disposition may be effected without violation of
               applicable federal or state securities laws.

               (v)    CERTIFICATES; LEGENDS. The certificates representing the
               Restricted Shares will bear restrictive legends noting the
               restrictions identified in the preceding clause, the Company's
               repurchase rights and the restrictions on transfer set forth in
               Section 7 of this Agreement.

          7.  LIMITATION ON TRANSFER. During the lifetime of the Optionee, only
the Optionee or his or her guardian or legal representative or transferee of a
transfer permitted by this Section may exercise the Option. The Optionee shall
not assign or transfer the Option or Restricted Shares issued upon early
exercise of the Option, except that the Optionee may transfer the Option by will
or the laws of descent and distribution. Any attempt to assign, transfer,
pledge, hypothecate or otherwise dispose of the Option or any Restricted Shares
contrary to the provisions hereof, and the levy of any attachment or similar
process upon the Option or any Restricted Shares, shall be null and void.

          8.  SHAREHOLDER RIGHTS BEFORE EXERCISE. The Optionee shall have none
of the rights of a shareholder of the Company with respect to any Share subject
to the Option until the Share is actually issued to him or her upon exercise of
the Option.

          9.  ADJUSTMENTS. The Committee may in its sole discretion make
appropriate adjustments in the number of Shares subject to the Option and in the
purchase price per Share to give effect to any adjustments made in the number of
outstanding Shares of the Company through a merger or consolidation (that is not
a Change in Control) or a recapitalization, stock dividend, stock split or other
relevant change, provided that fractional Shares shall be rounded to the nearest
whole share.

          10.  TAX WITHHOLDING. The parties hereto recognize that the Company or
a parent or subsidiary thereof may be obligated to withhold federal and state
income taxes and social security or other taxes upon the Optionee's exercise of
the Option. The Optionee agrees that, at the time he or she exercises the
Option, if the Company or a parent or subsidiary thereof is required to withhold
such taxes, he or she will promptly pay in cash upon demand to the Company, or
the parent or subsidiary having such obligation, such amounts as shall be
necessary to satisfy such obligation; provided, however, that in lieu of all or
any part of such a cash payment, the Board may, but shall not be required to,
permit the Optionee to elect to cover all or any part of the required
withholdings, and to cover any additional withholdings up to the amount needed
to cover the Optionee's full FICA and federal, state and local income taxes with
respect to income arising from the exercise of the Option, through a reduction
of the number of Shares delivered to the Optionee.

          11.  LOCK UP AGREEMENT. Optionee agrees that, upon the request of the
Company or the managing underwriter(s) in connection with a registration of
shares of the Company's Common Stock pursuant to Section 12 of the Securities
Exchange Act of 1934 (the "Exchange Act") for a period of time (not to exceed
180 days) from the effective date of the Company's registration under Section 12
of the Exchange Act, Optionee (or any transferee permitted under this Agreement)
shall not sell, make any short sale of, loan, grant any option for the purchase
of, or otherwise dispose of any shares of the Company's Common Stock owned or
controlled by it; provided, however, that, at the time of the request, the
Optionee is an officer or a member of the board of directors of the Company or
the Optionee holds (assuming exercise of all options and warrants, and the
conversion of all convertible

                                      5

<PAGE>   6

securities held by the Optionee, to the extent then exercisable or convertible)
an aggregate number of shares of the Company's Common Stock (or equivalent)
equal to at least one percent (1%) of the total number of shares of the
Company's Common Stock then issued and outstanding.

          12.  INTERPRETATION OF THIS AGREEMENT. All decisions and

Mr. Bruce D. Parker

Dear Bruce:

We are very pleased to offer to you the position of Executive Vice President of

agreement with the following terms please acknowledge your agreement with your
signature at the end of this letter and return copy to me.

Executive Vice President reporting to Jerry Greenberg, Co-CEO. Your
responsibilities will include internal development of the company organization,
management and infrastructure to sustain and promote growth, external
development of the company in new market development, International development,
merger and acquisitions, large client development and major customer deal
development. This responsibility will include the recruiting and hiring of other
senior leaders.

SAPIENT BOARD MEMBER

You will not be asked to resign from the Sapient Board of Directors because of
your employment with Sapient and you will remain a member of Sapient's Board of
Director, unless and until you are removed or not re-elected by the Sapient
stockholders. Jerry Greenberg and Stuart Moore agree to nominate for reelection
to the Board of Sapient as long as you remain employed by Sapient and to vote
their shares in favor of all such re-elections of your to the board. As an
employee-director, you will not receive any compensation for your participation
on the Board. Notwithstanding anything to the contrary included in Sapient's
stock option plans or stock option agreements, the stock options you currently
hold as a Board member will continue to vest according to their terms. As an
employee-Director, you will have to resign from the Audit and Compensation
committee of the Board as of your date of hire.

OUTSIDE BOARD MEMBERSHIP

<PAGE>   2

you will be allowed to be a member of the Board of Directors of one other
company as long as such company is not a competitor of Sapient and your
position does not pose any other type of conflict.

LOCATION

It is understood that you will maintain your personal residence in Miami, FL. In
addition to other locations, it is expected that you will spend a considerable
amount of your time working out of our Cambridge office. As such, Sapient will
provide you with an apartment in Cambridge or Boston at Sapient's expense
including all reasonable utilities, telephone service charges and miscellaneous
living expenses. Sapient will also reimburse you for your reasonable travel
expenses incurred in commuting to and from work from your Miami residence. In
the event you decide to relocate to Sapient's headquarters, or any other Sapient
location, Sapient will reimburse you for reasonable relocation expenses
including closing costs associated with the purchase and/or sale of a primary
residence, attorneys' fees, brokers' fees, recording of deeds and mortgages,
municipal liens, certified plot plans, document preparation, parking and moving
of your household goods, expenses incurred for two house hunting trips
associated with your relocation and other expenses typically reimbursed for
relocation of other senior executives of Sapient. In the event you resign from
Sapient prior to one year from being reimbursed for relocation expenses, you
agree to repay to Sapient such expenses within 30 days of your departure.

COMPENSATION

Your annual base salary will be $325,000, paid twice monthly. Your base salary
will be reviewed annually by Mr. Greenberg, Co-CEO, and the Board of Directors,
for potential increases taking into consideration your performance, Sapient's
financial condition and compensation competitiveness.

BONUS CASH COMPENSATION

In addition to your base salary, your cash compensation includes an annual cash
bonus target of $175,000. This performance incentive ("PI") target amount may
be increased annually with or without any increase of base salary.

SIGN-ON BONUS

Within 15 days of your first day of employment, you will be paid $450,000 as a
partial offset of the your loss of cash bonus and restricted stock from your
current employer as a result of leaving such employment to join Sapient. In
the event you resign from, or
<PAGE>   3
are terminated by Sapient for "cause" (defined below) prior to your third
anniversary, you will repay this bonus, or a portion thereof, within 30 days of
your departure. If you do leave Sapient prior to your third anniversary, the
amount to be repaid to Sapient would be calculated as follows: [(36 - the months
of employment)/36] times $450,000. Such repayment amount would be reduced by any
income taxes or wage-based taxes paid by you or withheld by Sapient on this
bonus. You agree to forward to Sapient any tax advantages from repayment that
should result to you that would exceed a neutral tax position.

DEFERRED COMPENSATION AND 401k PLAN CONTRIBUTIONS CAP

Before your start date we agree to work with you to structure the payout of your
1999 and 2000 cash compensation over time so that you are able to defer your
cash compensation, including 401(k) company matches, to future years if you
wish. You agree that after your start date, you will work on the potential
creation of a Sapient deferred compensation plan with a rabbi like trust to
enable Sapient executives to defer up to 100% of their cash compensation.

STOCK OPTIONS

In addition to your cash compensation, you will be granted stock options to
purchase Sapient common stock as set forth below. All such stock options will
have a term of ten years form the date of grant and will be granted at the
closing price of the Sapient common stock on the date of grant. Unless otherwise
set forth in this letter or your option agreements, all your options will vest
25% per year over four years beginning on the first day of the month following
the grant date. All your options will be incentive stock options to the extent
permissible under, and up to the limits permitted by, the Internal Revenue Code.
The Grant 1 and 2 options set forth below do account for our November 1999 two
for one stock split and are stated on a post-split basis. The Grant 3 option
grant will be adjusted for any future stock splits or changes in Sapient's
capitalization.

Grant 1 - 75,000 shares on or within 10 days of your first day of employment
Grant 2 - 50,000 shares within 90 days following January 1, 2000 Grant 3 -
Between 75,000 and 125,000 options within 90 days following January 1, 2001

The actual number of shares to be granted for Grant 3 will be calculated as
follows: 100,000 times 1.30 times the Grant 2 exercise price dividend by the
closing price of the Sapient common stock on the day of grant of Grant 3. In any
event, the total number of options granted for Grant 3 will not exceed 125,000
shares or be less than 75,000 shares.
<PAGE>   4
ADDITIONAL ANNUAL OPTION GRANTS

Annually beginning in 2001, you will be eligible to receive additional stock
option grants. The number of options granted to you will be at least equal to
the average number of option grants being granted to other senior executives
reporting to a Co-CEO and who have demonstrated similar performance as you.

RETIREMENT

You may retire at age 60 or an earlier age if agreeable to Sapient and you will
receive full retiree benefits to the extent allowable under Sapient's benefit
plans and such benefits will not be discounted in relation to your age or years
of service at retirement. Sapient does not currently have a defined retirement
benefits plan. However, we agree to establish such a Plan that is reasonable
and customary for a firm like Sapient. Notwithstanding anything to the contrary
included in Sapient's stock option plans or stock option agreement, all
unvested stock options held by you at the time of your retirement will vest
immediately in full on your retirement date.

CHANGE OF CONTROL / TERMINATION WITHOUT CAUSE / RESIGNATION FOR GOOD REASON

In the event of (a) an unsolicited take over of Sapient where over 50 percent
of Sapient's outstanding shares are acquired, or (b) an offer is made and
accepted that would result in the change of the board of directors or of Mr.
Greenberg as a co-CEO, or involve the dissolution or merger of Sapient with
another company, (a "Change of Control"), then notwithstanding anything to the
contrary included in Sapient's stock option plans or stock option agreements,
all options granted to you prior to the Change of Control will vest immediately
on the date the Change of Control is consummated and the term of such options
shall continue unchanged. In addition, you will receive a cash amount equal to
three times your then base salary and annual PI target. Such amount will be paid
to you in one lump sum following the consummation of the Change of Control.

In the event of a solicited merger or acquisition that would result in a merged
or acquiring company where more than 50 percent of the board of directors is no
longer made up of the previous members of the Sapient board of directors or Mr.
Greenberg does not remain as a co-CEO (a "Merger Event"), then notwithstanding
anything to the contrary included in Sapient's stock option plans or stock
option agreements, the number of months of employment under your option
agreements will increase by 24 months thus accelerating the vesting of your
options by 24 months.
<PAGE>   5

For the period of 24 months immediately following a Change of Control or Merger
Event, if you are terminated other than for "cause" or you resign because you
are assigned a new role of responsibilities that are substantially inconsistent
with your position, role or responsibilities as an Executive Vice President,
then notwithstanding anything to the contrary included in Sapient's stock option
plans or stock option agreements, any then remaining unvested options held by
you will vest immediately and the term of the options shall continue. In
addition, you will receive a cash amount equal to two times your then annual
base salary and PI target amount. Such amount will be paid to you in equal
installments throughout the two year period following your departure.

If there is no Change of Control or Merger Event but you are terminated by
Sapient other than for "cause", then, notwithstanding anything to the contrary
in Sapient's stock option plans or stock option agreements, the number of
months of employment under your agreements will increase by 24 months thus
accelerating the vesting of your options by 24 months and the original term of
the options shall continue. If Mr. Greenberg is the co-CEO at the time of your
termination, then as severance you will be paid an amount equal to one year of
your then annual base salary and PI target and such amount shall be paid to you
in equal installments throughout the one year period following your
termination. If Mr. Greenberg is not the co-CEO at the time you are terminated
without cause, then as severance you will be paid an amount equal to two years
of your then annual base salary and PI target and such amount shall be paid to
you in equal installments throughout the two year period following your
termination.

For purposes of this letter, "cause" means (a) having admitted to, or been
convicted of a felony or any crime involving moral turpitude; (b) the
abandonment of your duties for 30 days or more; (c) any breach by you of the
Non-Disclosure, Non-Solicitation and Non-Competition Agreement to be entered
into between you and Sapient; or (d) you have committed a material act that is
in direct conflict to normally accepted standards of corporate ethics and that
could reasonably be determined to damage Sapient's business, reputation or
financial condition or results of operations.

Upon your departure from Sapient, for whatever reason, you will not be entitled
to receive any cash payments or have any of the vesting of your stock options
accelerated as described in this letter if you have violated any terms of your
Non-Disclosure, Non-Solicitation and Non-Competition Agreement.

In the event your options are accelerated or you are paid severance or other
cash payments upon your departure from Sapient as described above, you agree
that in consideration of such payments or option acceleration, you will fully,
forever,
<PAGE>   6
irrevocably and unconditionally release, remise and discharge Sapient, its
officers, directors, stockholders, corporate affiliates, attorneys, agents and
employees ("Sapient Affiliates") from any and all claims, charges, complaints,
demands, actions, causes of actions, suits, rights, debts, sums of money,
costs, accounts, reckonings, covenants, contracts, agreements, promises,
doings, omissions, damages, executions, obligations, liabilities and expenses
(including attorneys' fees and costs), of every kind and nature which you ever
had or now have against Sapient or any Sapient Affiliate. You further agree not
to bring any complaints, charges or claims against Sapient or any Sapient
Affiliate with respect to any matters arising out of your employment with
Sapient.

VACATION

You will be eligible for 4 weeks of paid vacation in each calendar year
beginning in 2000.

INSURANCE

Following your hire date, you agree to review Sapient's life insurance benefits
with the intent to potentially create a life insurance benefit for Sapient's
executive officers.

CONTRACT

To the extent that either of us believe that this agreement needs to be
embodied in a formal contract we agree to develop in good faith such contract
agreements.
