("Parent"), (ii) CAPRI ACQUISITION CORP., a Delaware corporation and an indirect
wholly owned third-tier subsidiary of Parent ("Merger Sub"), (iii) MAINCONTROL,
INC., a Delaware corporation (the "Company"; Merger Sub and the Company being
hereinafter sometimes referred to collectively as the "Constituent
Corporations"), (iv) SHAI BEILIS, as agent for the Shareholders (the
"Shareholders' Representative") and (v) ALEX PINCHEV (the "Principal").

                               W I T N E S S E T H

            WHEREAS, the respective boards of directors of Parent, Merger Sub
and the Company have approved and adopted this Agreement, which provides for the
merger of Merger Sub with and into the Company (the "Merger") on the terms and
conditions set forth herein and in accordance with the provisions of the
Delaware General Corporation Law (the "Act");

            WHEREAS, the board of directors of the Company has recommended the
approval and adoption of this Agreement to its shareholders;

            WHEREAS, Parent, Merger Sub, the Company and the Principal desire to
make certain representations and warranties and other agreements in connection
with the Merger;

            WHEREAS, the parties intend that the Merger should constitute a
taxable transaction and should not qualify as a plan of reorganization within
the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the
"Code"); and

            WHEREAS, the Company intends to effect, prior to the Merger, a

Preferred Stock of the Company will be converted into shares of Common Stock of
the Company, (ii) the outstanding subordinated convertible notes of the Company
(the "Subordinated Notes") in the aggregate principal amount plus accrued
interest of approximately $12.7 million will be exchanged or converted into
shares of Common Stock of the Company, and (iii) the Company will file a
Certificate of Amendment to Certificate of Incorporation (the "Certificate of
Amendment") to increase the number of authorized shares of Common Stock of the
Company in order to accommodate the issuance of shares of Common Stock
contemplated by (i) and (ii) above (collectively, the "Recapitalization").

            NOW, THEREFORE, Parent, Merger Sub, the Company, the Shareholders'
Representative and the Principal hereby agree as follows:

            2.3 CONVERSION OF STOCK.

                  2.3.1 STOCK OF THE COMPANY. Subject to Section 2.4 and Section
2.7, at the Effective Time, each share of Common Stock of the Company issued and
outstanding immediately prior to the Effective Time (excluding any Dissenting
Shares) shall, by virtue of the Merger and without any action on the part of the
holder thereof (each such holder being hereinafter referred to as a
"Shareholder" and, collectively, as the "Shareholders") be converted into and
become .00022104 shares of the Common Stock of Parent amounting in the aggregate
to 1,100,000 shares of Common Stock of Parent ("Parent Stock"). Each share of
Parent Stock issued pursuant to the Merger shall be validly issued, fully paid
and nonassessable.

                  2.3.2 STOCK OF MERGER SUB. At the Effective Time, each share
of the Common Stock, par value $.001 per share, of Merger Sub ("Merger Sub
Stock") issued and outstanding immediately prior to the Effective Time shall, by

be converted into and become one validly issued, fully paid and nonassessable
share of Common Stock, par value $.001 per share, of the Surviving Corporation.

                  2.3.3 DISSENTING SHARES. Notwithstanding anything in this
Agreement to the contrary and unless otherwise provided by applicable law,
shares of capital stock of the Company that are issued and outstanding
immediately prior to the Effective Time and that are owned by Shareholders who
have properly demanded payment of the fair value of their stock (the "Dissenting
Shares") within the meaning of Section 262 of the Act shall not be converted
into the right to receive shares of Parent Stock pursuant to Section 2.3.1 above
unless and until such Shareholders shall have failed to perfect or shall have
effectively withdrawn their demand, or lost their right of payment under
applicable law. If any such Shareholder shall have failed to perfect or shall
have effectively withdrawn or lost such right of payment, each share of capital
stock held by such Shareholder shall thereupon be deemed converted into the
right to receive and exchangeable for, at the Effective Time, shares of Parent
Stock pursuant to Section 2.3.1 of this Agreement. Subject to the terms and
conditions of this Agreement, at and after the Effective Time, any holder of
shares of capital stock who complies with Section 262 of the Act (a "Dissenting
Shareholder") shall be entitled to obtain payment from the Surviving Corporation
of the fair value of such Dissenting Shareholder's shares of capital stock as
determined pursuant to the Act; PROVIDED, HOWEVER, that, to the extent
permissible under the Act, no such payment shall be made unless and until such
Dissenting Shareholder has surrendered to the Parent the certificate
representing the shares of capital stock for which payment is being made.

                  2.3.4 PROCEDURE WITH RESPECT TO DISSENTING SHARES. The Company
shall give Parent (i) prompt notice of any written notice of intent to demand
payment for shares filed pursuant to Section 262 of the Act received by the
Company, withdrawals of such notices, and any other instruments served in
connection with such notices pursuant to the relevant provisions of the Act and
received by the Company and (ii) the opportunity to direct all negotiations and
proceedings with respect to such notices under the Act consistent with the
obligations of the Company thereunder. The Company shall not, except with the
prior written consent of Parent (which shall not be unreasonably withheld), (A)
make any payment with respect to any such notice, (B) offer to settle or settle
any such notices or (C) waive any failure to timely deliver a written notice in
accordance with the Act.

                                      -8-


            2.4 FRACTIONAL SHARES; MINIMUM SHARES.

                  (a) No fraction of a share of Parent Stock will be issued by
virtue of the Merger, but in lieu thereof each holder of shares of Common Stock
of the Company who would otherwise be entitled to a fraction of a share of
Parent Stock (after aggregating all fractional shares of Parent Stock to be
received by such holder) shall receive from Parent an amount of cash (rounded up
to the nearest whole cent) equal to the product of:

                  (i)   such fraction, multiplied by

                  (ii)  the average closing price of a share of Parent Stock for
                        the ten most recent days that Parent Stock has traded
                        ending on the trading day immediately prior to the
                        Effective Time, as reported by the Nasdaq National
                        Market (the "Parent Stock Value").

                  (b) No number of shares of Parent Stock less than 100 shares
will be issued to any individual Shareholder by virtue of the Merger, but in
lieu thereof each Shareholder who would otherwise be entitled to receive a
number of shares of Parent Stock (after aggregating all shares of Parent Stock
or fractions thereof to be received by such holder) that is less than 100 shall
receive from Parent an amount of cash (rounded up to the nearest whole cent)
equal to the product of (i) such number of shares, multiplied by (ii) the Parent
Stock Value.

                  (c) Unless Parent otherwise elects, no shares of Parent Stock
will be issued to any Shareholder who at the Effective Time has not either (i)
executed and delivered the Registration Agreement or (ii) otherwise established
to the reasonable satisfaction of Parent that he is an "accredited investor"
within the meaning of Rule 501 promulgated under the Securities Act (each a
"Non-Accredited Stockholder"), but in lieu thereof, each such Non-Accredited
Stockholder who would otherwise be entitled to receive a number of shares of
Parent Stock shall receive from Parent an amount of cash (rounded up to the
nearest whole cent) equal to the product of (i) the number of shares of Parent
Stock that such Non-Accredited Stockholder would otherwise be entitled to
receive (after aggregating all shares of Parent Stock or fractions thereof to be
received by such holder) multiplied by (ii) the Parent Stock Value.

            2.5 ISSUANCE OF PARENT STOCK. Subject to Section 2.7, at and after
the Effective Time, upon surrender to Parent by each Shareholder of certificates
for the number of shares of Common Stock representing all of the shares of
Common Stock owned by such Shareholder, Parent shall issue and deliver to each
such Shareholder a certificate which shall be registered in the name of such
Shareholder and shall bear appropriate legends, and which together shall
represent the total number of shares of Parent Stock into which such
Shareholder's Common Stock has been converted.

            2.6 CLOSING. The closing of the Merger (the "Closing") shall take
place at the offices of Parent in Bedford, Massachusetts as soon as practicable

VI hereof (the "Closing Date").

                                      -9-


            2.7 ESCROW FUND.

                  (a) When making the issuances of Parent Common Stock pursuant
to Section 2.5 above, Parent shall withhold from the Shareholders a number of
shares of Parent Common Stock equal to twenty percent (20%) of the number of
Shares (rounded down to the nearest Share) included in the Merger Consideration
(the "Escrow Shares"). At the Closing, Parent shall deliver the Escrow Shares to
a bank or trust company selected by Parent and the Shareholders' Representative
(the "Escrow Agent"), to be held by the Escrow Agent or its nominee pursuant to
the provisions of an escrow agreement substantially in the form of Exhibit B
(the "Escrow Agreement"). The Escrow Shares will be represented by a certificate
or certificates issued in the name of the Escrow Agent.

                  (b) When making the cash payments pursuant to Section 2.4(c)
above, Parent shall withhold from such payments an amount equal to twenty
percent (20%) of the aggregate amont of such payments (the "Non-Accredited Cash
Portion"). When paying the Transaction Bonuses or Earn-Out Amount to certain
employees of the Company, as more fully described in Section 5.5 below, Parent
shall withhold from such payments an amount equal to twenty percent (20%) of the
aggregate amount of such payments (the "Management Escrow Portion"; the
Management Escrow Portion together with the Non-Accredited Cash Portion shall be
referred to as the "Escrow Cash"; the Escrow Cash together with the Escrow
Shares shall be referred to collectively as the "Escrow Fund"). At the Closing,
Parent shall deliver the Escrow Cash to the Escrow Agent to be held by the
Escrow Agent pursuant to the provisions of the Escrow Agreement.

                  (c) Twenty-five percent (25%) of the total Escrow Fund shall
be segregated from the rest of the Escrow Fund and shall be deposited in and
held as a separate escrow account that will be held solely to satisfy
indemnification claims for inaccuracies of the representations set forth in
Section 3.25 and Schedule 3.25 hereof in accordance with Article 8 and the
Escrow Agreement (the "Section 3.25 Escrow Account"). Subject to the next
sentence, the Section 3.25 Escrow Account shall be released and delivered to the
Shareholders and the Executives as their interests therein may appear on
September 30, 2003 (the "Section 3.25 Escrow Period"). In the event any member
of the Parent Group has made a claim pursuant to Article 8 against the Section
3.25 Escrow Account prior to the end of the Section 3.25 Escrow Period, then the
Escrow Agent will continue to retain in escrow a portion of the Section 3.25
Escrow Account sufficient to cover the amount of such claim until such claim is
fully and finally resolved (and shall release the remainder of the Section 3.25
Escrow Account at the end of the Section 3.25 Escrow Period) in accordance with
the Escrow Agreement. The Parent Group may recover against the entire Escrow
Fund with respect to such indemnification claims, and is not limited to the
Section 3.25 Escrow Account.

                  (d) Subject to Section 2.7(e), the Escrow Fund other than the
Section 3.25 Escrow Account (the "General Escrow Fund") shall be held by the
Escrow Agent until the second anniversary of the Closing Date (the "Escrow
Period"); provided that on the first anniversary of the Closing Date, the
excess, if any, of the General Escrow Fund over two-thirds (2/3) of the
aggregate amount initially deposited in the General Escrow Fund (including any
additional amounts contributed pursuant to Section 5.5) shall be released to the
Shareholders and

                                      -10-


the Executives in accordance with their respective interests therein, with the
remainder being held until the second anniversary of the Closing.

                  (e) In the event any member of the Parent Group has made a
claim under Article 8 prior to the end of the Escrow Period, then the Escrow
Agent will continue to retain in escrow a portion of the General Escrow Fund
sufficient to cover the amount of such claim until such claim is fully and
finally resolved (and shall release the remainder of the General Escrow Fund at
the end of the Escrow Period) in accordance with the Escrow Agreement.

                  (f) Any payments made out of the Escrow Fund for Parent Claims
shall be paid first with the Management Escrow Portion in accordance with the
Escrow Agreement. After the Management Escrow Portion has been paid out in full,
further payments out of the Escrow Fund for Parent Claims shall be made using
the Escrow Shares (including the cash proceeds from the sale of any Escrow
Shares) and the Non-Accredited Cash Portion in accordance with the Escrow
Agreement.

                  (g) In the event that this Agreement is approved by the
Shareholders of the Company pursuant to Section 251 of the Act, then each
Shareholder shall, at the Effective Time, by virtue of the Merger and his
receipt of any Merger Consideration, and without any further act of such
Shareholder, be deemed to have consented to and approved the use of the Escrow
Fund to satisfy any Parent Claims by members of the Parent Group in the manner
set forth herein and in the Escrow Agreement.

of the Escrow Fund in satisfaction of claims by the Parent Group); (iii) to take
all action necessary in connection with the defense and/or settlement of any

the Registration Agreement.

                  (c) In the event that the Shareholder's Representative dies,
is unable or becomes unable to perform his responsibilities hereunder or resigns
from such position, the remaining Shareholders shall, by election of the
Shareholders (or, if applicable, their respective heirs, legal representatives,
successors and assigns) who held a majority of the shares of Common Stock issued
and outstanding immediately prior to the Effective Time, select another
representative to fill such vacancy and such substituted representative shall be
deemed to be the Shareholders' Representative for all purposes of this
Agreement.

                  (d) All decisions and actions by the Shareholders'
Representative, including actions under the Registration Agreement, the Escrow
Agreement and the defense or settlement of any Parent Claims for which the
Shareholders may be required to indemnify members of the Parent Group pursuant
to Article 8 hereof (but only with respect to Parent Claims payable solely out
of the Escrow Fund), shall be binding upon all of the Shareholders, and no
Shareholder shall have the right to object, dissent, protest or otherwise
contest the same.

                  (e) Each Shareholder, by virtue of the Merger and his receipt
of any Merger Consideration, and each Executive, by executing and delivering the
Transaction Bonus Agreements, shall be deemed to have agreed, that:

                        (i) Parent shall be able to rely conclusively on the
instructions and decisions of the Shareholders' Representative relating to the
registration of the Parent Stock or to the settlement of any Parent Claims for
indemnification by members of the Parent Group pursuant to Article 8 hereof and
the Escrow Agreement or any other actions permitted or required to be taken by
the Shareholders' Representative hereunder, and no party hereunder shall have
any cause of action against any member of the Parent Group for any action taken

of the Shareholders' Representative;

                        (ii) all actions, decisions and instructions of the
Shareholders' Representative shall be conclusive and binding upon all of the
Shareholders and the Executives and no Shareholder or Executive shall have any
cause of action against the Shareholders' Representative for any action taken or
not taken, decision made or instruction given by the Shareholders'
Representative under this Agreement or the Escrow Agreement, except for fraud or
willful breach of this Agreement or the Escrow Agreement by the Shareholders'
Representative;

                        (iii) the provisions of this Section 2.8 are independent
and severable, are irrevocable and coupled with an interest and shall be
enforceable notwithstanding any rights or remedies that any Shareholder or
Executive may have in connection with the transactions contemplated by this
Agreement; and

                        (iv) the provisions of this Section 2.8 shall be binding
upon the heirs, legal representatives, successors and assigns of each
Shareholder and Executive, and any references in this Agreement to a Shareholder

the authorization granted in this Section 2.8 shall be borne by the Shareholders
pro rata and shall be payable out of the Escrow Fund; PROVIDED, HOWEVER, that
the aggregate amount of any payments to the Shareholders' Representative out of
the Escrow Fund pursuant to this Section 2.8(f) shall not exceed $10,000. Parent
shall be entitled, without making any inquiry as to the validity or amount of
the fees or expenses to be reimbursed, to rely on the written instructions of
the Shareholders' Representative regarding payments in respect of the
Shareholders' Representative's fees and expenses as conclusive evidence of the
Shareholders' Representative right to receive such amounts.

            2.9 TRANSFERS OF OWNERSHIP. If any certificate for shares of Parent
Stock is to be issued in a name other than that in which the certificate
surrendered in exchange therefor is registered, it will be a condition of the

endorsed and otherwise in proper form for transfer and that the Shareholder
requesting such exchange will have paid to Parent or any agent designated by it
any transfer or other taxes required by reason of issuance of a certificate for
shares of Parent Stock in any name other than that of the registered holder of
the certificate surrendered, or established to the reasonable satisfaction of
Parent or any agent designated by it that such tax has been paid or is not
payable, (b) Parent will have received an opinion, in form and substance
reasonably satisfactory to Parent and its counsel, of counsel which (to Parent's
reasonable satisfaction) is knowledgeable in securities laws matters, to the

be effected without registration under the Securities Act and qualification
under any applicable state securities laws and (c) the party in whose name the
certificate will be issued has signed the Registration Agreement and any other

Schedule contains a correct and complete list of all pension, profit sharing,
retirement, deferred compensation, welfare, legal services, medical, dental or
other employee benefit or health insurance plans, life insurance or other death
benefit plans, disability, stock option, stock purchase, stock compensation,
bonus, vacation pay, severance pay and other similar plans, programs or
agreements, and every material personnel policy, relating to any persons
employed by the Company or in which any person employed by the Company is
eligible to participate and which is currently maintained or that was maintained
at any time in the last five calendar years by the Company (collectively, the
"Company Plans"). The Company has provided or made available to Parent complete
copies, as of the date hereof, of all of the Company Plans that have been
reduced to writing, together with all documents establishing or constituting any
related trust, annuity contract, insurance contract or other funding instrument,
and summaries of those that have not been reduced to writing. The Company has
provided or made available to Parent complete copies of current plan summaries,
employee booklets, personnel manuals and other material documents or written
materials concerning the Company Plans, as well as copies of the most recent
annual reports (Form 5500 series, including all schedules thereto), if
applicable, for the Company Plans. The Company does not have any "defined
benefit plans" as defined in Section 3(35) of ERISA.

                  3.11.2 ERISA. Neither the Company nor any ERISA Affiliate of
the Company has incurred any "withdrawal liability" calculated under Section
4211 of ERISA and there has been no event or circumstance which would cause them
to incur any such liability. Neither the Company nor any ERISA Affiliate of the
Company has ever maintained a Company Plan providing health or life insurance
benefits to former employees, other than as required pursuant to Section 4980B
of the Code or state law. No pension plan previously maintained by the Company
or its ERISA Affiliates which was subject to ERISA has been terminated; no
proceedings to terminate any such plan have been instituted within the meaning
of Subtitle C of Title IV of ERISA; and no reportable event within the meaning
of Section 4043 of said Subtitle C of Title IV of ERISA with respect to which
the requirement to file a notice with the Pension Benefit Guaranty Corporation
has not been waived has occurred with respect to any such Company Plan, and no
liability to the Pension Benefit Guaranty Corporation has been incurred by the
Company or its ERISA Affiliates. With respect to all the Company Plans, the
Company and every ERISA Affiliate of the Company are in material compliance with
all requirements prescribed by all statutes, regulations, orders or rules
currently in effect, and have in all material respects performed all obligations
required to be performed by them. Neither the Company nor any ERISA Affiliate of
the Company, nor any of their directors, officers, employees or agents,

                                      -20-


nor any trustee or administrator of any trust created under the Company Plans,
has engaged in or been a party to any "prohibited transaction" as defined in
Section 4975 of the Code and Section 406 of ERISA which could subject the
Company or its Affiliates, directors or employees or the Company Plans or the
trusts relating thereto or any party dealing with any of the Company Plans or
trusts to any material tax or material penalty on "prohibited transactions"
imposed by Section 4975 of the Code. Neither the Company Plans nor the trusts
created thereunder have incurred any "accumulated funding deficiency," as such
term is defined in Section 412 of the Code and regulations issued thereunder,
whether or not waived.

                  3.11.3 PLAN DETERMINATIONS. Each Company Plan intended to
qualify under Section 401(a) of the Code has been determined by the Internal
Revenue Service to so qualify, and the trusts created thereunder have been
determined to be exempt from tax under Section 501(a) of the Code; copies of all
determination letters have been delivered to the Company; and nothing has
occurred since the date of such determination letters which might cause the loss
of such qualification or exemption. With respect to each Company Plan which is a
qualified profit sharing plan, all employer contributions accrued for plan years
ending prior to the Closing under the Company Plan terms and applicable law have
been made.

                  3.11.4 FUNDING. Except as set forth on Schedule 3.11 hereto:

as of the Effective Time or are properly reflected on the Company Balance Sheet;

                        (b) there are no actions, liens, suits or claims pending
or, to the knowledge of the Company or the Principal, threatened (other than
routine claims for benefits) with respect to any Company Plan;

                        (c) no event has occurred, and there exists no condition
or set of circumstances, which presents a material risk of a partial termination
(within the meaning of Section 411(d)(3) of the Code) of any Company Plan;

                        (d) each Company Plan that is a "group health plan" (as
defined in Section 607(1) of ERISA) has been operated at all times in
substantial compliance with the provisions of COBRA and any applicable, similar
state law;

                        (e) the consummation of the Merger and the other
transactions contemplated by this Agreement will not: (1) entitle any current or
former employee of the Company to severance pay, unemployment compensation or
any similar payment, (2) accelerate the time of payment or vesting, or increase
the amount of any compensation due to, any current or former employee of the
Company, (3) constitute or involve a "prohibited transaction" as defined in
Section 4975 of the Code and Section 406 of ERISA, constitute or involve a
breach of fiduciary responsibility within the meaning of Section 502(1) of ERISA
or otherwise violate Part 4 of Title I of ERISA or (4) result in the payment of
compensation that would, in combination with any other payment, result in an
"excess parachute payment" within the meaning of Section 280G(b) of the Code;
and

                                      -21-


                        (f) with respect to any Company Plan that is qualified
under Section 401(k) of the Code, individually and in the aggregate, no event
has occurred, and to the knowledge of the Company or the Principal, there exists
no condition or set of circumstances in connection with which the Company could
be subject to any liability that is reasonably likely to have a Company Material
Adverse Effect (except liability for benefits claims and funding obligations
payable in the ordinary course) under ERISA, the Code or any other applicable
law.

agreement, nor entitle any other party to any such license, sublicense or
agreement to terminate or modify such license, sublicense or agreement.

PTO to be confidential), know-how and other confidential Company Proprietary
Rights, and there have been no acts or omissions by the officers, directors and
shareholders of the Company or, to the knowledge of the Company or the

Proprietary Rights have been asserted, and, to the knowledge of the Company,

bona fide claims (a) to the effect that the development, sale, licensing or use
of any of the products of the Company as now developed, sold or licensed or used
or proposed for development, use, sale or licensing by the Company infringes on
any copyright, patent, trademark, service mark or trade secret, (b) against the
use by the Company of any trademarks, service marks, trade names, trade secrets,
copyrights, patents, technology, know-how or computer software programs and
applications used in the Company's business as currently conducted or as
proposed to be conducted by the Company, or (c) challenging the ownership by the

Right or product of the Company is subject to any outstanding decree, order,
judgment, or stipulation known to the Company that restricts in any manner the
licensing thereof by the Company.

                  3.18.2 VALIDITY. All contracts, leases, instruments, licenses
and other agreements or documents described on Section 3.18 of the Company
Disclosure Schedule are valid and in full force and effect and the Company has
not, nor, to the knowledge of the Company or the Principal, has any other party
thereto, breached any provision of, or defaulted under the terms of any such
contract, lease, instrument, license or other agreement or document. Section
3.18 of the Company Disclosure Schedule identifies each agreement and other
document set forth on Section 3.18 of the Company Disclosure Schedule or
disclosed by the Company on another part of the Company Disclosure Schedule that
requires the consent of a third party in connection with the transactions
contemplated hereby.

            3.19 INSURANCE CONTRACTS. Section 3.19 of the Company Disclosure
Schedule lists all contracts of insurance in force at the date hereof with
respect to the Company. Such contracts of insurance (collectively, the "Company
Insurance Contracts") insure against such risks, and are in such amounts, as are
reasonable and appropriate considering the Company and its property, business
and operations. To the best of the Company's knowledge, all of the Company
Insurance Contracts are in full force and effect. The Company has committed no
default under any such Insurance Contract which could permit the insurer to deny
payment of claims thereunder. The execution and delivery of this Agreement by
the Company, and the

                                      -28-


consummation of the transactions contemplated hereby, will not cause the Company
to be in violation or default under any Company Insurance Contracts, nor entitle
any other party thereto to terminate or modify a Company Insurance Contract. The
Company has not received or given a notice of cancellation with respect to any
of the Company Insurance Contracts.

            3.20 BANKING RELATIONSHIPS. Section 3.20 of the Company Disclosure
Schedule shows the names and locations of all banks and trust companies in which
the Company has accounts, lines of credit or safety deposit boxes and, with
respect to each account, line of credit or safety deposit box, the names of all
persons authorized to draw thereon or to have access thereto.

            3.21 SUPPLIERS, DISTRIBUTORS AND CUSTOMERS. Since the date of the
Company Balance Sheet, no material supplier, distributor or customer of the
Company has cancelled or otherwise modified its relationship with the Company in
a manner that is materially adverse to the Company and, to the knowledge of the
Company or the Principal, no supplier, distributor or customer of the Company
has any intention to do so.

            3.22 PRODUCT WARRANTY. Each product sold, leased, licensed or
delivered by the Company has been in conformity in all material respects with
all contractual commitments and all express and implied warranties applicable
thereto. Since January 1, 2000, the warranty expenses incurred by the Company
have not been material to the Company in the aggregate. The Company has no
notice of any claim of failure of its products to conform to any applicable
contractual commitments or warranties that could give rise to material liability
on the part of the Company. Schedule 3.22 hereto includes copies of the standard
terms and conditions of license and sale for the Company (containing applicable
warranty and indemnity provisions). Except as set forth on Schedule 3.22, no
product sold, leased, licensed or delivered by the Company is subject to any
guaranty, warranty, or other indemnity that differs in any material respect from
the applicable standard terms and conditions of license and sale and such other
indemnities and warranties disclosed on Schedule 3.22, other than differences
that, individually or in the aggregate, could not reasonably be expected to give
rise to material liability on the part of the Company.

            3.23 POTENTIAL CONFLICTS OF INTEREST. No officer or director of the
Company: (i) owns, directly or indirectly, any interest in (excepting not more
than 5% stock holdings for investment purposes in securities of publicly held
and traded companies) or is an officer, director, employee or consultant of any
Person that is a direct competitor listed on Schedule 3.23, or a significant
lessor, lessee, customer or supplier of the Company; (ii) owns, directly or
indirectly, in whole or in part, any Company Proprietary Rights; (iii) has any
cause of action or other claim whatsoever against the Company, except for claims
in the ordinary course of business, such as for accrued vacation pay, accrued

date hereof; (iv) has made, on behalf of the Company, any payment or commitment
to pay any commission, fee or other amount to, or purchase or obtain or
otherwise contract to purchase or obtain any goods or services from, any
corporation or other Person of which any officer or director of the Company, or,
to the knowledge of the Company or the Principal, a relative of any of the
foregoing, is a partner, shareholder or other securityholder (except stock
holdings solely for investment purposes in securities of publicly held and
traded companies); or (v) as of the date hereof or at any time since January 1,
2001, owes or owed any

                                      -29-


money to the Company (except for normal expense reimbursements and similar
obligations for advances made by the Company to such person in the ordinary
course of business and not material in amount).

            3.24 ACCOUNTING SYSTEM. To the knowledge of the Company or the
Principal, the Company maintains a system of internal accounting controls
sufficient to provide reasonable assurance that (a) transactions are executed in
accordance with management's general or specific authorizations; (b)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with GAAP and to maintain asset accountability; (c)
access to assets is permitted only in accordance with management's general or
specific authorization; and (d) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

true and correct.

            3.26 Full Disclosure. This Agreement, including the Company
Disclosure Schedule, does not contain any untrue statement by the Company of a
material fact or omit to state a material fact necessary to be stated to make
the statements by the Company contained herein not false or misleading.

                                    ARTICLE 5

                  (a) Prior to the Closing, the Company shall use commercially
reasonable efforts to cooperate with Parent in granting access to employees of
the Company for employment interviews at such time and in such manner as Parent
and the Company shall reasonably

                                      -33-


determine. At least five (5) business days before the expected Closing, Parent
shall deliver written notice to the Company identifying the employees of the

normal business practices. The Retained Employees will be required to execute
Parent's standard paperwork, including, without limitation, Parent's current

laws, Parent shall (i) waive limitations as to preexisting conditions,
exclusions and waiting periods with respect to participation and coverage, and

Effective Time in satisfying any applicable deductible or out-of-pocket
requirements under any benefit plans of Parent.

of the Company to remain in the employment of the Company or become employed by
the Parent, affect the right of the Company to terminate any employee at any
time, or affect the right of the Parent to establish, modify or terminate any
employee benefit plan or any benefit under any such plan at any time.

            5.5 TRANSACTION BONUS AGREEMENTS.

Executive and collectively the "Executives") who is a participant in the
Transaction Bonus Plan will enter into a Transaction Bonus Agreement in
substantially the form of Exhibit D (collectively, the "Transaction Bonus
Agreements"). Subject to Section 2.7 and the remainder of this paragraph, Parent
will provide for the payment by the Company to such Executives transaction
bonuses in the aggregate amount of $3,500,000 (the "Transaction Bonus Amount").
Two Million Two Hundred Forty Thousand Dollars ($2,240,000) of the Transaction
Bonus


                                      -34-

Amount will be paid at the Closing to the Executives in the amounts set forth on
Schedule 5.5 and Five Hundred Sixty Thousand Dollars ($560,000) of the
Transaction Bonus will be placed in escrow in accordance with Section 2.7(b).
Payment of the remaining Seven Hundred Thousand ($700,000) of the Transaction
Bonus Amount (the "Earn Out Amount"), will be contingent upon Revenues (as
defined below) reaching certain thresholds during the following periods (each an
"Earn Out Period"), as follows:

            (i) if $5,000,000 or more in Revenues is achieved between the date
of Closing and September 30, 2002, 100% of the Earn Out Amount will be paid, and
clauses (ii) through (iv) below will be inapplicable;

            (ii) if $3,000,000 or more but less than $5,000,000 in Revenues is
achieved between the date of Closing and September 30, 2002, 60% of the Earn Out
Amount will be paid;

            (iii) if the sum of Revenues achieved between October 1, 2002 and
December 31, 2002 plus Revenues achieved between the date of Closing and
September 30, 2002 in excess of $3,000,000 equals at least $1,000,000 but less
than $2,000,000, 20% of the Earn Out Amount will be paid; and

            (iv) if the sum of Revenues achieved between October 1, 2002 and
December 31, 2002 plus Revenues achieved between the date of Closing and
September 30, 2002 in excess of $3,000,000 equals or exceeds $2,000,000, an
additional 20% of the Earn Out Amount will be paid.

            Payments of the Earn Out Amount, if any, in respect of any Earn Out
Period shall be made within five business days following the date that Parent's
independent public accountants complete its quarterly review or audit, as the
case may be, and such audit or review shows that such Earn Out Amount is
achieved. In connection with payments of the Earn Out Amount, 80% of each such
payment shall be paid to the Executives in the proportions set forth on Schedule
5.5, and 20% of each such payment will be placed in escrow in accordance with
Section 2.7(b).

            For purposes of this Section, "Revenue" means revenue of the Company
determined in accordance with GAAP and recognized by the Parent attributable to
sales of new software licenses of the Company's products, plus the amount of the
first year's maintenance fees attributable to such new licenses. If Parent
shall, prior to December 31, 2002, (1) cease to offer for sale or announce that
it will no longer provide support for the products of the Company, (2) reduce
the number of full-time direct sales representatives employed by the Company or
the Parent who devote all or substantially all of their activities as an
employee to selling the Company's products to fewer than four (4) persons, (3)
cease to provide support at an executive level for the marketing and sale of the
Company's products, (4) cease to position the Company's products as part of the
Parent's strategic portfolio of products, (5) cease to provide or announce that
it will no longer provide support for any current platform for the products of
the Company, (6) fire without cause any of the Principal, John deWit, Werner
Knoblich, Rachel Cassidy or Hector Nevarez that are employed by Parent after the
Merger (other than as agreed with such person prior to or contemporaneously with
the Closing), (7) refuse to honor the terms of any existing proposals made on
commercially reasonable terms by the Company to potential

                                      -35-

customers, (8) act unreasonably in the negotiation of the final terms with
potential customers with the purpose of frustrating the closing of new license
transactions or (9) otherwise act in bad faith in order to avoid paying the all
or part of the Earn Out Amount pursuant to this Section 5.5 (each an "Earn Out
Acceleration Event"), then, notwithstanding the failure of the Company to
achieve the minimum Revenues specified for any such period, within ten business
days of the occurrence of such Earn Out Acceleration Event, and only if and to
the extent that such Earn Out Acceleration Event(s) demonstrably contributed to
the failure to achieve the applicable Revenue threshold, Parent will pay 100% of
the Earn Out Amount; provided, that if the Earn Out Acceleration Event occurs
after September 30, 2002, only 40% of the Earn Out Amount will be paid pursuant
to this clause.

            5.6   RESIGNATIONS. Each member of the board of directors of the
Company shall resign as a director of the Company, effective as of the Effective
Time. Each officer of the Company shall resign as an officer, effective as of
the Effective Time.

            5.7   PUBLIC ANNOUNCEMENTS. No party to this Agreement shall issue
any press release or make any public announcement relating to the terms of this
Agreement prior to the Effective Time without the prior approval of the other
parties hereto (which approval shall not be unreasonably withheld); PROVIDED,
HOWEVER, that any party to this Agreement may make any public disclosure it
believes in good faith is required by applicable law or any listing agreement
concerning its publicly-traded securities (in which case the disclosing party
will use its reasonable best efforts to advise the other parties prior to making
the disclosure).

            5.8   FURTHER ASSURANCES. Subject to terms and conditions herein
provided, each of the parties, severally and not jointly, agree to use all
reasonable efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate and make effective the Merger and the other
transactions contemplated by this Agreement. Without limiting the generality of
the foregoing, Parent and the Company each, severally and not jointly, will use
all reasonable efforts to obtain all approvals, authorizations, consents and
waivers from, and give all notices to, any public or private third parties that
are necessary on its, his or her part in order to effect the transactions
contemplated hereby.

            5.9   Directors' and Officers' Insurance; Indemnification.

                  (a) Parent agrees to maintain in effect in accordance with
their terms all rights to indemnification in respect of acts or omissions
occurring prior to the Effective Time that now exist in favor of current or
former officers or directors of the Company as provided in the certificate of
incorporation or bylaws of the Company as in effect on the date of this
Agreement.

                  (b) For a period of three years after the Effective Time, the
Surviving Corporation shall maintain in effect, if available, directors' and
officers' liability insurance (the "Tail Policy") covering those persons who are
currently covered by the Company's directors' and officers' liability insurance
policy (a copy of which has been made available to Parent) on terms comparable
to those now applicable to directors and officers of the Company with respect to
any occurrence prior to the closing; provided, however, that in no event shall
the Surviving Corporation be required to expend in excess of $100,000 for such
coverage, and that if the

                                      -36-

premium for such coverage exceeds such amount, the Surviving Corporation shall
purchase a policy with the largest policy limit available for $100,000.

            5.10  COMERICA BANK LINE. Prior to the Closing, the Company shall
pay in full all outstanding amounts owed under its Loan and Security Agreement
between Comerica Bank - California, successor in interest to Imperial Bank, and
the Company as amended to April 20, 2001 (the "Comerica Bank Line"). The Company
and the Parent shall cooperate in good faith and use their commercially
reasonable efforts to have the letter of credit issued by Comerica Bank on
behalf of the Company to secure the obligations of the Company under the
Washington Real Estate Investment Trust Office Building Lease by and between
WRIT Limited Partnership and the Company terminated and released as security for
such obligations. Parent will assume the obligations of the Company under that
certain Warrant to Purchase Stock dated April 20, 2001 issued to Comerica Bank -
California, successor in interest to Imperial Bank, by the Company, to the
extent that it is still outstanding at the Effective Time.

Closing.

            5.12  TAXABLE TRANSACTION. It is intended by the parties hereto that
the Merger shall constitute a taxable transaction and shall not constitute a
tax-free reorganization within the meaning of Section 368 of the Code. Each
party hereto agrees not to take any position contrary to such intention with any
Government Entity, including, without limitation, on any Tax returns or other
filings. In connection therewith, for a period of two years, Parent agrees to
take (or refrain from taking) such actions as may be requested by the
Shareholders' Representative and that as confirmed by the Parent's tax advisors
are reasonably necessary to cause the Merger not to constitute a taxable
transaction. In particular, Parent hereby agrees to maintain the Company as a
third tier (or lower) subsidiary in Parent's corporate organizational structure
for such two-year period. For purposes of this Agreement, a "third tier"
subsidiary means a subsidiary that is held by a corporation through two
intermediate holding corporations above such subsidiary and below the parent
corporation.

            5.13 SHAREHOLDER APPROVAL. The Company agrees to use reasonable
efforts to obtain the approval of the holders of a majority of the shares of
Company Common Stock (after giving effect to the Recapitalization), excluding
shares held by any holder of Common Stock who prior to the Recapitalization was
a holder of a Subordinated Note.

                  the date of this Agreement (the "Termination Date") (unless
                  the failure to consummate the Merger is attributable to a
                  failure on the part of the party seeking to terminate this
                  Agreement to perform any material obligation required to be
                  performed by such party at or prior to the Termination Date);

                  INDEMNIFICATION; SURVIVAL OF REPRESENTATIONS

            8.1   AGREEMENT TO INDEMNIFY.

                  8.1.1 PARENT CLAIMS. Subject to the terms and conditions of
this Article 8, each Shareholder, by virtue of the Merger and his receipt of any
Merger Consideration, and the Principal, hereby jointly and severally agree
(without any right of contribution from the Company or the Surviving Corporation
or any right of indemnification against the Company or the Surviving
Corporation) to indemnify, defend and hold harmless Parent and each of its
Subsidiaries and each of their respective directors, officers, agents and
Affiliates (collectively, the "Parent Group") from and against any out-of-pocket
loss, liability, damage, cost or expense (including reasonable attorneys' fees
and disbursements and including amounts paid as deductibles under the Tail
Policy) suffered, incurred or paid by any member of the Parent Group
(collectively, all such amounts are hereinafter referred to as "Parent Claims")
which arise out of or are attributable to any of the following:

                        (a) failure of any of the representations, warranties,
                  covenants and agreements of the Company and the Principal
                  contained in this Agreement including the Company Disclosure
                  Schedule or in any other agreement, certificate or other
                  document among or between the parties contemplated by or
                  referred to herein (with respect to representations and
                  warranties) to be true, complete and correct in all material
                  respects or (with respect to covenants and agreements) fully
                  performed and fulfilled in all material respects;

                        (b) the Company's failure to pay Taxes in any
                  jurisdiction prior to the date hereof (regardless of any
                  disclosure thereof herein) ("Tax Claims");

                        (c) the assertion by any stockholder of the Company of
                  any claim, or institution by any such stockholder of any
                  action or proceeding, which arises out of the issuance and
                  sale of the Subordinated Notes, the Recapitalization or the
                  merger or the transactions contemplated hereby (excluding any
                  proceeding for appraisal of such stockholder's shares pursuant
                  to Section 262 of the Act); or

                                      -40-

                        (d) any fraud or any fraudulent misrepresentation
                  committed by the Company, a Shareholder or the Principal in
                  connection with the transactions contemplated by this
                  Agreement ("Fraud Claims").

                  8.1.2 BENEFIT OF PARENT GROUP. With respect to any member of
the Parent Group other than Parent, the Shareholders, the Shareholders'
Representative and the Principal acknowledge and agree that Parent is
contracting on its own behalf and for such member and Parent shall obtain and
hold the rights and benefits provided for in this Section 8.1 in trust for and
on behalf of such member.

            8.2   SURVIVAL. All representations, warranties, covenants and
agreements made by any party in this Agreement or any certificate or other
writing delivered pursuant hereto or in connection herewith shall survive the
Closing and any investigation at any time made by or on behalf of any other
party for a period of one year from the Closing Date, provided, however, that
the representations and warranties set forth in Sections 3.10, 3.17 and 3.25
shall survive the Closing and any investigation at any time made by or on behalf
of any other party for a period of two years from the Closing;

            8.3   LIMITATION OF SHAREHOLDERS' AND PRINCIPAL'S LIABILITY FOR
CERTAIN PARENT CLAIMS.  The obligations and liabilities of the Shareholders and
the Principal hereunder with respect to indemnification for Parent Claims shall
be subject to the following limitations:

                        (a) All Parent Claims against any Shareholder or the
                  Principal shall be made exclusively against the Escrow Fund
                  except with respect to Fraud Claims. None of the Shareholders
                  or the Principal shall have any liability under or arising out
                  of the terms of this Agreement except as set forth in the
                  immediately preceding sentence. No Parent claims may be
                  brought against the Section 3.25 Escrow Account except for
                  Parent Claims pursuant to Article 8 solely relating to or
                  arising out of any inaccuracy in the representations in
                  Section 3.25 or Schedule 3.25.

                        (b) No indemnification shall be required to be made by
                  the Shareholders or the Principal hereunder and no Parent
                  Claims may be brought against the Escrow Fund unless the
                  amount of Parent Claims exceeds $100,000 in the aggregate, in
                  which case the Shareholders' and the Principal's
                  indemnification obligations shall apply to all Parent Claims
                  without regard to such threshold.

                        (c) For purposes of determining the amount of property
                  recoverable from the Escrow Fund sufficient to satisfy a
                  Parent Claim subject to indemnification hereunder, the value
                  of a share of Parent Stock shall be equal to the
                  Indemnification Value. For purposes hereof, "Indemnification
                  Value" means (i) with respect to any recovery hereunder
                  determined by arbitration proceeding, the average of the
                  prices at which the Parent Stock last traded on each of the
                  twenty trading days immediately preceding the date of the
                  award from such proceeding, as such prices are reported on the
                  Nasdaq National Market, (ii) in the case of a recovery
                  hereunder determined by written agreement between Parent and
                  the Shareholders' Representative, the average of the prices at
                  which the Parent Stock last traded on each of the twenty
                  trading days immediately preceding the date of such agreement,
                  as such prices are reported on the Nasdaq National

                                      -41-

                  Market, and (iii) in the case of a recovery hereunder where
                  the Shareholders' Representative is deemed not to dispute the
                  Parent Claim or the amount of the recovery because the
                  Shareholders' Representative has not responded as provided in
                  Section 8.4.2, the average of the prices at which the Parent
                  Stock last traded on each of the twenty trading days
                  immediately preceding the date that is 45 days after the
                  Shareholders' Representative and the Escrow Agent were given
                  notice of such Parent Claim pursuant to Section 8.4.1 and the
                  Escrow Agreement, as such prices are reported on the Nasdaq
                  National Market.

                        (d) With respect to Parent Claims arising out of or
                  relating to Fraud Claims, only those Shareholders or
                  Principals who are responsible for such Fraud Claims shall be
                  liable for indemnification hereunder in excess of the Escrow
                  Fund.

                        (e) No Parent Claims may be brought against the Escrow
                  Fund for any Tax imposed on or incurred by the Company as a
                  result of an election made under Section 338(g) of the Code by
                  Parent or its Affiliates with respect to the Merger. None of
                  the Shareholders or the Principal shall have any liability
                  arising out of or as a result of any Tax imposed on or
                  incurred by the Company as a result of an election made under
                  Section 338(g) of the Code by Parent or its Affiliates with
                  respect to the Merger.

            8.4   PROCESS OF INDEMNIFICATION FOR PARENT CLAIMS.

                  8.4.1 RECOVERY BY PARENT. In seeking to collect the amount of
any Parent Claim that a member of the Parent Group has established and is
entitled to indemnification for hereunder, Parent shall first give the
Shareholders' Representative and the Escrow Agent written notice of such Parent
Claim. Such notice shall contain a brief summary of the basis for the Parent
Claim. If the Shareholders' Representative does not dispute the basis or amount
of any Parent Claim within 45 days of receiving written notice thereof, Parent
shall have the right promptly to recover indemnity as and to the extent provided
herein. If the Shareholders' Representative disagrees with the basis of the
Parent Claim or the amount of damages caused thereby, then within 45 days of
receiving written notice thereof, the Shareholders' Representative shall give
notice to Parent of such disagreement and, in that case, Parent shall have no
right to recover indemnity hereunder until such time, if at all, as (a) an
arbitrator has issued a decision from an arbitration proceeding completed
pursuant to the Escrow Agreement (subject to the limitations contained in
Article 8) or (b) Parent and the Shareholders' Representative agree in writing
to the amount of Parent's recovery, in which case Parent shall have the right
promptly to recover the amount so agreed.

                  8.4.2 THIRD-PARTY PARENT CLAIMS. Parent agrees to notify the
Shareholders' Representative promptly of any Parent Claims asserted by third
parties that, in the opinion of Parent, are reasonably likely to give rise to
indemnification hereunder ("Third-Party Parent Claims"). Parent shall permit the
indemnifying party or parties to assume the defense of any such Third-Party
Parent Claim, provided that counsel for the indemnifying parties, who shall
conduct the defense of such Third-Party Parent Claim, shall be subject to the
approval of Parent (whose approval shall not be unreasonably withheld). Parent
may participate in such defense at its own expense; provided, however, that the
indemnifying parties shall pay such expense if Parent shall have reasonably
concluded that there is a substantial probability of a conflict

                                      -42-

between the positions of the indemnifying parties and Parent in conducting the
defense of any such Third-Party Parent Claim or that there may be legal defenses
available to it that are different from or additional to those available to the
indemnifying parties. Parent agrees that it will not settle any Third-Party
Parent Claims without the consent of the Shareholders' Representative, which
consent shall not be unreasonably withheld or delayed. Parent further agrees
that if the Shareholders' Representative wishes to enter into a settlement with
respect to a Third-Party Parent Claim on terms reasonably acceptable to Parent,
Parent will cooperate in such settlement, provided that such settlement
includes, as an unconditional term thereof, the giving by the third party to
Parent of a release from all liability in respect of such Third-Party Parent
Claim.

                                  MISCELLANEOUS

            9.1   AMENDMENTS AND SUPPLEMENTS. This Agreement may not be amended,
modified or supplemented by the parties hereto in any manner, except by an
instrument in writing signed by Parent, the Company, the Principal and the
Shareholders' Representative.

            9.2   WAIVER. The terms and conditions of this Agreement may be
waived only by a written instrument signed by the party waiving compliance. The
failure of any party hereto to enforce at any time any of the provisions of this
Agreement shall in no way be construed to be a waiver of any such provision, nor
in any way to affect the validity of this Agreement or any part hereof or the
right of such party thereafter to enforce each and every such provision. No
waiver of any breach of or non-compliance with this Agreement shall be held to
be a waiver of any other or subsequent breach or non-compliance. The rights and
remedies herein provided are cumulative and are not exclusive of any rights or
remedies that any party may otherwise have at law or in equity.

            9.3   GOVERNING LAW. This Agreement shall be governed by, and
construed and enforced in accordance with, the substantive laws of The
Commonwealth of Massachusetts, without regard to its principles of conflicts of
laws. The parties agree to submit to the exclusive jurisdiction of any state or
federal court located in The Commonwealth of Massachusetts with respect to any
dispute that arises under this Agreement or in connection with the transactions
contemplated hereby.

referenced in Section 5.2 and the documents and instruments and other agreements
among the parties hereto as contemplated by or referred to herein constitute the
entire agreement among the parties with respect to the subject matter hereof and

both written and oral, between the parties with respect to the subject matter

Party") brings a claim in litigation against another party hereto (a "Defending
Party") relating to or arising out of this Agreement, and a court of competent
jurisdiction issues a final, non-appealable order specifying that the Charging
Party has not prevailed on any part of such claim, then the Charging Party shall
pay to the Defending Party the reasonable costs and expenses (including
reasonable attorneys' fees and disbursements) of the Defending Party in
defending such claim.

            9.9   COUNTERPARTS. This Agreement may be executed in one or more
