---------------------
[Name of Employee]

      You are executing this agreement because you have agreed to participate in
the Exchange Applications, Inc. (the "Company") stock option exchange program.
You hereby agree with the Company as follows:

      1. SURRENDER AND CANCELLATION OF STOCK OPTIONS. You are hereby
surrendering all unexercised stock options evidenced by the stock option
agreements listed on Schedule A attached hereto (the "Cancelled Options"). You
agree that if the Company requests, you promptly will surrender to the Company
the original stock option agreements governing such stock options. You represent
to the Company that the stock options listed on Schedule A includes all stock
options granted to you at any time on or after June 15, 2000. The information
set forth on Schedule A with respect to the Cancelled Options is true and
correct as of today's date.

      2. GRANT OF NEW STOCK OPTIONS. On June 18, 2001 (the "New Grant Date"), so
long as you are still then employed by the Company, the Company will grant to
you stock options to purchase the same number of shares of the Company's common
stock surrendered by you under paragraph 1 above (the "New Options"). The
exercise price per share of the New Options will be the fair value of the
Company's common stock as of the close of business on the day immediately
preceding the New Grant Date.

      Except as set forth below with respect to unvested "performance-based"
options, the timetable for the vesting of the New Options will be identical to
the vesting timetable for the Cancelled Options (so that you will be vested in
your New Options, if granted, as you would have been under your Cancelled
Options). New Options being issued in respect of Cancelled Options that were
"performance-based" options, if granted, will be vested to the extent they were
vested as of the date they became Cancelled Options and for those options that
were not vested as of the date they became Cancelled Options will vest in ten
equal quarterly installments on the last day of each calendar quarter,
commencing June 30, 2001.

      YOU ACKNOWLEDGE AND UNDERSTAND THAT BY ENTERING INTO THIS AGREEMENT YOU
HAVE IRREVOCABLY AND UNCONDITIONALLY (I) GIVEN UP ALL RIGHTS AND INTERESTS UNDER
THE CANCELLED OPTIONS, AND (II) AGREED THAT, UNLESS YOU ARE EMPLOYED BY THE
COMPANY ON JUNE 18, 2001, THE COMPANY SHALL HAVE NO OBLIGATION OF ANY KIND TO
ISSUE OR GRANT TO YOU AND YOU WILL HAVE NO RIGHTS TO RECEIVE ANY NEW OPTIONS OR
ANY OTHER RIGHTS OR CONSIDERATION IN RESPECT OF YOUR CANCELLED OPTIONS.

      3.  RECLASSIFICATIONS OF COMMON STOCK; ADJUSTMENTS. In the event on or
prior to the New Grant Date of any reclassification of or change to the
Company's common stock, or in the case of any consolidation or merger of the
Company with or into another corporation (other than a merger in which the
Company is a continuing corporation and which does not result in any
reclassification or change of the Company's common stock), the number of shares
of common stock or other securities under, and the exercise price under the New
Options shall be appropriately and equitably adjusted to give effect to such
event. In the event on or prior to the New Grant Date of any subdivision or
combination of the Company's common stock the exercise price and the number of
shares of the Company's common stock to be covered by the New Options, if and
when granted to you, shall be appropriately and equitably adjusted to give
effect to such event.

      4.  DISCLAIMERS. This agreement (i) shall not be deemed a contract of
employment and you shall continue to be an employee "at will," and (ii) shall
not confer to you any rights upon your termination of employment by the Company.

      5. MISCELLANEOUS. This agreement shall be governed by and interpreted in
accordance with the laws of The Commonwealth of Massachusetts (without reference
to principles of conflicts or choice of law). This agreement may be executed in
counterparts (including by telecopier), each of which shall be an original and
all of which taken together shall constitute one and the same agreement. This
agreement shall inure to the benefit of and be binding upon the Company and its
successors and assigns. Your rights under this agreement may not be transferred
or assigned to any person or entity, by operation of law or otherwise.

                            ---------------------------
Dear Mr. Parekh:

         This letter is to confirm the understanding between Exchange
Applications, Inc. ("Exchange") and each of Insight Capital Partners IV, L.P.,
Insight Capital Partners (Cayman) IV, L.P., Insight Capital Partners IV (Fund
B), L.P. and Insight Capital Partners IV (Co-Investors), L.P. (collectively,
"Insight") with respect to the following:

         (i)  Insight will refinance (the "Refinancing") Exchange's obligations
              under the 9% Bridge Promissory Note, dated February 20, 2001, and
              the 10% Bridge Promissory Note, dated March 28, 2001, each made by
              Exchange payable to the order of Insight, with a new loan to be
              governed by a new $4,500,000 promissory note (the "New Note")
              bearing interest at 12% per annum, having a maturity of January
              15, 2002, and accelerating upon a Sale of the Corporation (as
              defined in clause (ii) below). In connection with the Refinancing,
              Exchange will issue a new warrant (the "Replacement Warrant") that
              will replace the Warrant (No. W-1), dated February 20, 2001, and
              the Warrant (No. W-2), dated March 28, 2001, each issued by
              Exchange to Insight. Pursuant to the Replacement Warrant, Exchange
              will agree to issue to Insight 681,818 shares of Exchange common
              stock for a per share exercise price equal to the lowest daily
              closing price on the Nasdaq National Market for shares of Exchange
              common stock between February 20, 2001 and the earliest of (x)
              date of exercise of the Replacement Warrant, (y) the date of
              payment in full of the New Note and (z) the date of conversion
              of all of the obligations outstanding under the New Note. The
              Replacement Warrant will expire ten years after its issuance.

         (ii) At any time from the date hereof through the earlier of (x)
              December 31, 2001 and (y) the consummation of a Sale of the
              Corporation (as such term is defined in the Certificate of
              Designation with respect to the Company's Series A Preferred

                                       -2-

              Stock, filed with the Delaware Secretary of State on January
              _10__, 2001) (the "Financing Period"), upon the request of
              Exchange, so long as (i) Exchange has complied with the terms
              hereunder the terms of the Warrant (No. W-3) dated the date hereof
              and issued by Exchange to InSight and the terms of the Series A
              Preferred Stock, (ii) Exchange has used its best efforts to obtain
              financing from other investors and has not succeeded in obtaining
              such financing and (iii) with respect to any amount of Financing
              to be provided under this clause (ii) in excess of $6,500,000,
              Exchange has not failed to achieve in excess of 70% of the revenue
              projections (the "Target") released to the public immediately
              after its scheduled April 27, 2001 earnings conference call (or,
              as reasonably determined by Insight, not failed to be realizing
              sufficient revenues during the remainder of calendar year 2001 so
              as to permit the achievement of the Target), Insight will, subject
              to customary conditions, provide Exchange with financing (the
              "Financing") of up to $13,500,000 for purposes of supporting its
              ongoing business operations on terms to be negotiated in good
              faith between Insight and Exchange, provided, however, that any
              debt securities purchased by Insight pursuant to a Financing shall
              have a maturity date of no sooner than January 15, 2002.

         The parties undertakings to issue or purchase securities in the
circumstances contemplated by this letter are subject to compliance with
applicable laws (including all regulatory and listing requirements).

         Exchange agrees to indemnify and hold Insight harmless from and against
any and all damages, losses, liabilities and reasonable expenses that may be
incurred by Insight from third party claims arising out of or in connection with
this letter and the transactions contemplated hereby. The obligations of
Exchange under this paragraph shall survive the expiration or termination of
this letter for any reason.

         Nothing in this letter is intended to confer upon any person other than
the parties hereto any rights, remedies, obligations or liabilities under or by
reason of this letter. Insight shall be entitled to assign its rights or
delegate its duties hereunder to third parties so long all such third parties
shall agree in writing to perform its obligations hereunder and such third
parties have the financial capacity to comply with this letter, if applicable.
Insight shall have no obligations hereunder in the event that Exchange shall be
subject to a bankruptcy proceeding (whether voluntary or involuntary) or shall
assign its assets for the benefit of creditors. This letter shall be governed by
the laws of the State of New York, without giving effect to its conflicts of law
principles. Any obligation of the Insight entities hereunder to make an
investment in Exchange shall be allocated among each of the Insight entities in
accordance with the percentages allocated among such entities when making
investments generally (in accordance with such Insight entities' governing
documents) and no Insight entity shall be obligated to invest in excess of such
<PAGE>

                                       -3-

percentage of any investment to be made hereunder. Exchange shall reimburse
Insight for all legal fees and all legal or other expenses related to the
preparation, negotiation and enforcement of this letter as well as any
documentation respecting any of the transactions contemplated herein.
