                           CHANGE IN CONTROL AGREEMENT

                                                      _____________ ___, 200_

Dear _____________________,

         This letter agreement  ("Agreement")  will confirm the terms of certain
compensation due to you by SoundBite Communications, Inc. and any successor (the
"Company") in the event of a change in control of the Company.

         1.  Upon the (i) sale by the Company, whether in cash or securities, of
all or substantially all of its assets or (ii) merger or consolidation of the
Company with or into another entity in a transaction where the shares of the
Company's capital stock outstanding immediately prior to the closing of such
merger or consolidation represent or are converted into or exchanged for shares
that represent less than a majority of the shares of capital stock of the
resulting or surviving entity outstanding immediately after the closing of such
merger or consolidation (each of the foregoing being referred to as "Change in
Control"), then 25% of all unvested stock, options, awards and purchase rights
granted to you under any of the stock plans or stock option plans of the Company
prior to such Change in Control shall immediately become fully vested and
exercisable as of the effective date of a Change in Control. Notwithstanding
the foregoing, the issuance by the Company of its capital stock in an equity
financing, either in a private or public transaction, shall not constitute a
Change in Control.

        2.  Upon the occurrence of any one of the events set forth in (A), (B)
or (C) below within six (6) months following the closing of a Change in Control,
you will be entitled to receive 100% of all unvested stock, options, awards and
purchase rights granted to you under any of the stock plans or stock option
plans of the Company prior to the occurrence of any such event shall immediately
become fully vested and exercisable as of the effective date of such event:

                (A)      the termination of your employment for any reason other
                         than Cause (as defined below); or

                (B)      the substantial reduction in the scope or nature of
                         your responsibilities, duties, authorities, position,
                         powers or reporting structure or relationships in
                         effect immediately prior to a Change in Control
                         (other than for Cause); or

                (C)      the Company moves your place of employment more than
                         50 miles from the location in effect immediately prior
                         to a Change in Control.

        For purposes of this Agreement, "Cause" shall mean termination for any
one of the following reasons: (x) your willful misconduct or gross negligence in
the performance of your duties as an employee and officer of the Company (as
determined by a majority of the directors of the Company other than, if
applicable, you) or (y) criminal misconduct by you in connection with the
performance of your duties as an employee and officer of the Company.

        3.  Nothing in this Agreement is intended, or shall be construed, to
restrict or otherwise limit the Company's right to terminate your employment
with or without Cause and with or without notice. This letter is not a guarantee
of continued employment, it being understood you are and continue to be employed
at-will. The benefits set forth in this Agreement shall constitute liquidated
damages and shall be your exclusive remedy for any claims arising under or in
connection with this Agreement or the termination of your employment
relationship as a result of a Change in Control.

        4.  This Agreement shall constitute the sole and entire agreement among
the parties with respect to the subject matter hereof, and supersedes and
cancels all prior, concurrent and/or contemporaneous arrangements,
understandings, agreements and/or discussions, whether written or oral, by or
among the parties regarding the subject matter hereof; provided, however, that
this Agreement is not intended to, and shall not, supersede, affect, limit,
modify or terminate any of the following, all of which shall remain in full
force and effect in accordance with their respective terms: (i) any written
stock or stock option agreements between you and the Company (except as
expressly modified hereby); (ii) any written agreements between you and the
Company concerning noncompetition, nonsolicitation, inventions and/or
nondisclosure obligations; and (iii) any written agreements between you and the
Company that do not relate to the subject matter hereof.

        5.  You may not assign any rights or delegate any duties or obligations
under this Agreement. The Company will require their respective assigns and
successors to assume this Agreement and to agree to perform hereunder in the
same manner and to the same extent that the Company would be required to perform
if no such succession or assignment had taken place. Regardless of whether such
an agreement is executed, this Agreement shall inure to the benefit of, and be
binding upon, the Company's respective successors and assigns and your heirs,
estate, legatees, executors, administrators, and legal representatives.
