                           Change-in-Control Agreement

      THIS AGREEMENT by and between Applix, Inc., a Massachusetts corporation
(the "Company"), and Craig Cervo (the "Employee") is made as of April 9, 2003
(the "Effective Date").

      WHEREAS, the Company recognizes that, as is the case with many
publicly-held corporations, the possibility of a change in control of the
Company exists and that such possibility, and the uncertainty and questions
which it may raise among key personnel, may result in the departure or
distraction of key personnel to the detriment of the Company and its
stockholders, and

      WHEREAS, the Company has determined that appropriate steps should be taken
to reinforce and encourage the continued employment and dedication of the
Company's key personnel without distraction from the possibility of a change in
control of the Company and related events and circumstances.

      NOW, THEREFORE, as an inducement for and in consideration of the Employee
remaining in its employ, the Company agrees that the Employee shall receive the
severance benefits set forth in this Agreement in the event the Employee's
employment with the Company is terminated under the circumstances described
below subsequent to a Change in Control (as defined in Section 1.1).

      1. Key Definitions.

      As used herein, the following terms shall have the following respective
meanings:

            1.1 "Change in Control" means an event or occurrence set forth in
any one or more of subsections (a) through (d) below (including an event or
occurrence that constitutes a Change in Control under one of such subsections
but is specifically exempted from another such subsection):

                  (a) the acquisition by an individual, entity or group (within
the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
1934, as amended (the "Exchange Act")) (a "Person") of beneficial ownership of
any capital stock of the Company if, after such acquisition, such Person
beneficially owns (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) 50% or more of either (i) the then-outstanding shares of common
stock of the Company (the "Outstanding Company Common Stock") or (ii) the
combined voting power of the then-outstanding securities of the Company entitled
to vote generally in the election of directors (the "Outstanding Company Voting
Securities"); provided, however, that for purposes of this subsection (a), the
following acquisitions shall not constitute a Change in Control: (i) any
acquisition directly from the Company (excluding an acquisition pursuant to the
exercise, conversion or exchange of any security exercisable for, convertible
into or exchangeable for common stock or voting securities of the Company,
unless the Person exercising, converting or exchanging such security acquired
such security directly from the Company or an underwriter or agent of the
Company), (ii) any acquisition by the Company, (iii) any acquisition by any
employee benefit plan (or related trust) sponsored or maintained by the
<PAGE>
Company or any corporation controlled by the Company, or (iv) any acquisition by
any corporation pursuant to a transaction which complies with clauses (i) and
(ii) of subsection (c) of this Section 1.1; or

                  (b) such time as the Continuing Directors (as defined below)
do not constitute a majority of the Board of Directors of the Company (the
"Board") (or, if applicable, the Board of Directors of a successor corporation
to the Company), where the term "Continuing Director" means at any date a member
of the Board (i) who was a member of the Board on the date of the execution of
this Agreement or (ii) who was nominated or elected subsequent to such date by
at least a majority of the directors who were Continuing Directors at the time
of such nomination or election or whose election to the Board was recommended or
endorsed by at least a majority of the directors who were Continuing Directors
at the time of such nomination or election; provided, however, that there shall
be excluded from this clause (ii) any individual whose initial assumption of
office occurred as a result of an actual or threatened election contest with
respect to the election or removal of directors or other actual or threatened
solicitation of proxies or consents, by or on behalf of a person other than the
Board; or

                  (c) the consummation of a merger, consolidation,
reorganization, recapitalization or statutory share exchange involving the
Company or a sale or other disposition of all or substantially all of the assets
of the Company in one or a series of transactions (a "Business Combination"),
unless, immediately following such Business Combination, each of the following
two conditions is satisfied: (i) all or substantially all of the individuals and
entities who were the beneficial owners of the Outstanding Company Common Stock
and Outstanding Company Voting Securities immediately prior to such Business
Combination beneficially own, directly or indirectly, more than 50% of the
then-outstanding shares of common stock and the combined voting power of the
then-outstanding securities entitled to vote generally in the election of
directors, respectively, of the resulting or acquiring corporation in such
Business Combination (which shall include, without limitation, a corporation
which as a result of such transaction owns the Company or substantially all of
the Company's assets either directly or through one or more subsidiaries) (such
resulting or acquiring corporation is referred to herein as the "Acquiring
Corporation") in substantially the same proportions as their ownership,
immediately prior to such Business Combination, of the Outstanding Company
Common Stock and Outstanding Company Voting Securities, respectively; and (ii)
no Person (excluding the Acquiring Corporation or any employee benefit plan (or
related trust) maintained or sponsored by the Company or by the Acquiring
Corporation) beneficially owns, directly or indirectly, 30% or more of the then
outstanding shares of common stock of the Acquiring Corporation, or of the
combined voting power of the then-outstanding securities of such corporation
entitled to vote generally in the election of directors (except to the extent
that such ownership existed prior to the Business Combination); or

                  (d) approval by the stockholders of the Company of a complete
liquidation or dissolution of the Company.

            1.2 "Change in Control Date" means the first date during the Term
(as defined in Section 2) on which a Change in Control occurs. Anything in this
Agreement to the contrary notwithstanding, if (a) a Change in Control occurs,
(b) the Employee's employment with the Company is terminated prior to the date
on which the Change in Control occurs, and (c) it is


                                       2
<PAGE>
reasonably demonstrated by the Employee that such termination of employment (i)
was at the request of a third party who has taken steps reasonably calculated to
effect a Change in Control or (ii) otherwise arose in connection with or in
anticipation of a Change in Control, then for all purposes of this Agreement the
"Change in Control Date" shall mean the date immediately prior to the date of
such termination of employment.

            1.3 "Cause" means:

                  (a) the Employee's willful and continued failure to
substantially perform his/her reasonable assigned duties as an employee of the
Company (other than any such failure resulting from incapacity due to physical
or mental illness or any failure after the Employee gives notice of termination
for Good Reason), which failure is not cured within 30 days after a written
demand for substantial performance is received by the Employee from the Company
which specifically identifies the manner in which the Company believes the
Employee has not substantially performed the Employee's duties; or

                  (b) the Employee's willful engagement in illegal conduct or
gross misconduct which is materially and demonstrably injurious to the Company.

      For purposes of this Section 1.3, no act or failure to act by the Employee
shall be considered "willful" unless it is done, or omitted to be done, in bad
faith and without reasonable belief that the Employee's action or omission was
in the best interests of the Company.

            1.4 "Good Reason" means the occurrence, without the Employee's
written consent, of any of the events or circumstances set forth in clauses (a)
through (g) below. Notwithstanding the occurrence of any such event or
circumstance, such occurrence shall not be deemed to constitute Good Reason if,
prior to the Date of Termination specified in the Notice of Termination (each as
defined in Section 3.2(a)) given by the Employee in respect thereof, such event
or circumstance has been fully corrected and the Employee has been reasonably
compensated for any losses or damages resulting therefrom (provided that such
right of correction by the Company shall only apply to the first Notice of
Termination for Good Reason given by the Employee).

                  (a) the assignment to the Employee of duties inconsistent in
any material respect with the Employee's position (including status, offices,
titles and reporting requirements), authority or responsibilities in effect
immediately prior to the earliest to occur of (i) the Change in Control Date,
(ii) the date of the execution by the Company of the initial written agreement
or instrument providing for the Change in Control or (iii) the date of the
adoption by the Board of Directors of a resolution providing for the Change in
Control (with the earliest to occur of such dates referred to herein as the
"Measurement Date"), or any other action or omission by the Company which
results in a material diminution in such position, authority or
responsibilities; provided, however, that if the Employee terminates his/her
employment for Good Reason pursuant to this paragraph, he/she must provide to
the Company or the acquiring entity, during the three month period following the
Change in Control Date, such cooperation as the Company or acquiring entity may
reasonably request with respect to transition matters, which cooperation shall
not entail a commitment by the Employee of more than 20 hours per month;


                                       3
<PAGE>
                  (b) a reduction in the Employee's annual base salary as in
effect on the Measurement Date or as the same was or may be increased thereafter
from time to time;

                  (c) the failure by the Company to (i) continue in effect any
material compensation or benefit plan or program (including without limitation
any life insurance, medical, health and accident or disability plan and any
vacation or automobile program or policy) (a "Benefit Plan") in which the
Employee participates or which is applicable to the Employee immediately prior
to the Measurement Date, unless an equitable arrangement (embodied in an ongoing
substitute or alternative plan) has been made with respect to such plan or
program, (ii) continue the Employee's participation therein (or in such
substitute or alternative plan) on a basis not materially less favorable, both
in terms of the amount of benefits provided and the level of the Employee's
participation relative to other participants, than the basis existing
immediately prior to the Measurement Date or (iii) award cash bonuses to the
Employee in amounts and in a manner substantially consistent with past practice
in light of the Company's financial performance;

                  (d) a change by the Company in the location at which the
Employee performs his/her principal duties for the Company to a new location
that is both (i) outside a radius of 35 miles from the Employee's principal
residence immediately prior to the Measurement Date and (ii) more than 20 miles
from the location at which the Employee performed his/her principal duties for
the Company immediately prior to the Measurement Date; or a requirement by the
Company that the Employee travel on Company business to a substantially greater
extent than required immediately prior to the Measurement Date;

                  (e) the failure of the Company to obtain the agreement from
any successor to the Company to assume and agree to perform this Agreement, as
required by Section 6.1;

                  (f) any failure of the Company to pay or provide to the
Employee any portion of the Employee's compensation or benefits due under any
Benefit Plan within seven days of the date such compensation or benefits are
due, or any material breach by the Company of this Agreement or any employment
agreement with the Employee.

      For purposes of this Agreement, any good faith determination of "Good
Reason" made by the Employee shall be conclusive, binding and final. The
Employee's right to terminate his/her employment for Good Reason shall not be
affected by his/her incapacity due to physical or mental illness.

            1.5 "Disability" means the Employee's absence from the full-time
performance of the Employee's duties with the Company for 180 consecutive
calendar days as a result of incapacity due to mental or physical illness which
is determined to be total and permanent by a physician selected by the Company
or its insurers and acceptable to the Employee or the Employee's legal
representative.

      2. Term of Agreement. This Agreement, and all rights and obligations of
the parties hereunder, shall take effect upon the Effective Date and shall
expire upon the first to occur of (a) the expiration of the Term (as defined
below) if a Change in Control has not occurred during the


                                       4
<PAGE>
Term, (b) the termination of the Employee's employment prior to the Change in
Control Date, (c) the date 12 months after the Change in Control Date, if the
Employee is still employed by the Company as of such later date, or (d) the
fulfillment by the Company of all of its obligations under Sections 4 and 5.2 if
the Employee's employment with the Company terminates within 12 months following
the Change in Control Date. "Term" shall mean the period commencing as of the
Effective Date and continuing in effect through December 31, 2004; provided,
however, that commencing on January 1, 2005 and each January 1 thereafter, the
Term shall be automatically extended for one additional year unless, not later
than 90 days prior to the scheduled expiration of the Term (or any extension
thereof), the Company shall have given the Employee written notice that the Term
will not be extended.

      3. Employment Status; Termination Following Change in Control.

            3.1 Not an Employment Contract. The Employee acknowledges that this
Agreement does not constitute a contract of employment or impose on the Company
any obligation to retain the Employee as an employee and that this Agreement
does not prevent the Employee from terminating employment at any time. If the
Employee's employment with the Company terminates for any reason and
subsequently a Change in Control shall occur, the Employee shall not be entitled
to any benefits hereunder except as otherwise provided pursuant to Section 1.2.

            3.2 Termination of Employment.

                  (a) If the Change in Control Date occurs during the Term, any
termination of the Employee's employment by the Company or by the Employee
within 12 months following the Change in Control Date (other than due to the
death of the Employee) shall be communicated by a written notice to the other
party hereto (the "Notice of Termination"), given in accordance with Section 7.
Any Notice of Termination shall: (i) indicate the specific termination provision
(if any) of this Agreement relied upon by the party giving such notice, (ii) to
the extent applicable, set forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Employee's
employment under the provision so indicated and (iii) specify the Date of
Termination (as defined below). The effective date of an employment termination
(the "Date of Termination") shall be the close of business on the date specified
in the Notice of Termination (which date may not be less than 15 days or more
than 120 days after the date of delivery of such Notice of Termination), in the
case of a termination other than one due to the Employee's death, or the date of
the Employee's death, as the case may be.

                  (b) The failure by the Employee or the Company to set forth in
the Notice of Termination any fact or circumstance which contributes to a
showing of Good Reason or Cause shall not waive any right of the Employee or the
Company, respectively, hereunder or preclude the Employee or the Company,
respectively, from asserting any such fact or circumstance in enforcing the
Employee's or the Company's rights hereunder.

                  (c) Any Notice of Termination for Cause given by the Company
must be given within 90 days of the occurrence of the event(s) or
circumstance(s) which constitute(s) Cause.

      4. Benefits to Employee.

            4.1 Stock Option Acceleration. If the Change in Control Date occurs
during the Term, then, effective upon the Change in Control Date, each
outstanding option to purchase shares of Common Stock of the Company held by the
Employee shall become immediately exercisable in full and will no longer be
subject to a right of repurchase by the Company.

            4.2 Compensation. If the Change in Control Date occurs during the
Term and the Employee's employment with the Company terminates within 12 months
following the Change in Control Date, the Employee shall be entitled to the
following benefits:

                  (a) Termination Without Cause or for Good Reason. If the
Employee's employment with the Company is terminated by the Company (other than
for Cause, Disability or Death) or by the Employee for Good Reason within 12
months following the Change in Control Date, then the Employee shall be entitled
to the following benefits:

                        (i) the Company shall pay to the Employee in a lump sum
in cash within 30 days after the Date of Termination the sum of (A) the
Employee's base salary through the Date of Termination, (B) any accrued bonus
which the Employee is entitled to receive as of the Date of Termination, (C) the
amount of any compensation previously deferred by the Employee (together with
any accrued interest or earnings thereon) and any accrued vacation pay, in each
case to the extent not previously paid (the sum of the amounts described in
clauses (A), (B), and (C) shall be hereinafter referred to as the "Accrued
Obligations"); and

                        (ii) for six months after the Date of Termination, the
Company shall continue to pay to the Employee his/her highest annual base salary
during the three-year period prior to the Date of Termination.

                  (b) Resignation without Good Reason; Termination for Cause or
for Death or Disability. If the Employee voluntarily terminates his/her
employment with the Company within 12 months following the Change in Control
Date, excluding a termination for Good Reason, or if the Employee's employment
with the Company is terminated by the Company for Cause or by reason of the
Employee's death or Disability within 12 months following the Change in Control
Date, then the Company shall pay the Employee (or his/her estate, if
applicable), in a lump sum in cash within 30 days after the Date of Termination,
the Accrued Obligations.

            4.3 Mitigation. The Employee shall not be required to mitigate the
amount of any payment or benefits provided for in this Section 4 by seeking
other employment or otherwise. Further, the amount of any payment or benefits
provided for in this Section 4 shall not be reduced by any compensation earned
by the Employee as a result of employment by another employer.

      5. Disputes.

            5.1 Settlement of Disputes; Arbitration. All claims by the Employee
for benefits under this Agreement shall be directed to and determined by the
Board of Directors of the Company and shall be in writing. Any denial by the
Board of Directors of a claim for


                                       6
<PAGE>
benefits under this Agreement shall be delivered to the Employee in writing and
shall set forth the specific reasons for the denial and the specific provisions
of this Agreement relied upon. The Board of Directors shall afford a reasonable
opportunity to the Employee for a review of the decision denying a claim. Any
further dispute or controversy arising under or in connection with this
Agreement shall be settled exclusively by arbitration in Boston, Massachusetts,
in accordance with the rules of the American Arbitration Association then in
effect. Judgment may be entered on the arbitrator's award in any court having
jurisdiction.

            5.2 Expenses. The Company agrees to pay as incurred, to the full
extent permitted by law, all legal, accounting and other fees and expenses which
the Employee may reasonably incur as a result of any claim or contest
(regardless of the outcome thereof) by the Company, the Employee or others
regarding the validity or enforceability of, or liability under, any provision
of this Agreement or any guarantee of performance thereof (including as a result
of any contest by the Employee regarding the amount of any payment or benefits
pursuant to this Agreement), plus in each case interest on any delayed payment
at the applicable Federal rate provided for in Section 7872(f)(2)(A) of the
Code.

      6. Successors.

            6.1 Successor to Company. The Company shall require any person or
entity that purchases all or substantially all of the assets of the Company
expressly to assume and agree to perform this Agreement to the same extent that
the Company would be required to perform it if no such purchase had taken place.
As used in this Agreement, "Company" shall mean the Company as defined above and
any successor to its business or assets as aforesaid which assumes and agrees to
perform this Agreement, by operation of law or otherwise.

            6.2 Successor to Employee. This Agreement shall inure to the benefit
of and be enforceable by the Employee's personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees and
legatees. If the Employee should die while any amount would still be payable to
the Employee or his/her family hereunder if the Employee had continued to live,
all such amounts, unless otherwise provided herein, shall be paid in accordance
with the terms of this Agreement to the executors, personal representatives or
administrators of the Employee's estate.

      7. Notice. All notices, instructions and other communications given
hereunder or in connection herewith shall be in writing. Any such notice,
instruction or communication shall be sent either (i) by registered or certified
mail, return receipt requested, postage prepaid, or (ii) prepaid via a reputable
nationwide overnight courier service, in each case addressed to the Company, at
289 Turnpike Road, Westboro, Massachusetts 01581, and to the Employee at the
address set forth below his/her name on the signature page hereto (or to such
other address as either the Company or the Employee may have furnished to the
other in writing in accordance herewith). Any such notice, instruction or
communication shall be deemed to have been delivered five business days after it
is sent by registered or certified mail, return receipt requested, postage
prepaid, or one business day after it is sent via a reputable nationwide
overnight courier service. Either party may give any notice, instruction or
other communication hereunder using any other means, but no such notice,
instruction or other communication shall be


                                       7
<PAGE>
deemed to have been duly delivered unless and until it actually is received by
the party for whom it is intended.

      8. Miscellaneous.

            8.1 Employment by Subsidiary. For purposes of this Agreement, the
Employee's employment with the Company shall not be deemed to have terminated
solely as a result of the Employee continuing to be employed by a wholly-owned
subsidiary of the Company.

            8.2 Severability. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
effect.

            8.3 Injunctive Relief. The Company and the Employee agree that any
breach of this Agreement by the Company is likely to cause the Employee
substantial and irrevocable damage and therefore, in the event of any such
breach, in addition to such other remedies which may be available, the Employee
shall have the right to specific performance and injunctive relief.

            8.4 Governing Law. The validity, interpretation, construction and
performance of this Agreement shall be governed by the internal laws of the
Commonwealth of Massachusetts, without regard to conflicts of law principles.

            8.5 Waivers. No waiver by the Employee at any time of any breach of,
or compliance with, any provision of this Agreement to be performed by the
Company shall be deemed a waiver of that or any other provision at any
subsequent time.

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

            8.7 Tax Withholding. Any payments provided for hereunder shall be
paid net of any applicable tax withholding required under federal, state or
local law.

            8.8 Entire Agreement. This Agreement sets forth the entire agreement
of the parties hereto in respect of the subject matter contained herein and
supersedes all prior agreements (including but not limited to any stock option
acceleration agreement between the Company and the Employee), promises,
covenants, arrangements, communications, representations or warranties, whether
oral or written, by any officer, employee or representative of any party hereto
in respect of the subject matter contained herein; and any prior agreement of
the parties hereto in respect of the subject matter contained herein is hereby
terminated and cancelled. Notwithstanding the foregoing, in the event that this
Agreement is terminated as a result of (a) the expiration of the Term prior to
the occurrence of a Change in Control or (b) the termination of the Employee's
employment by the Company prior to the Change in Control Date, any such stock
option acceleration agreement shall not be superseded and shall continue in full
force and effect in accordance with its terms.
