                      AGREEMENT AND PLAN OF REORGANIZATION

         This AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made
and entered into as of January 20, 2000 among Concord Communications, Inc., a
Massachusetts corporation ("Parent"), F Acquisition Corp., a Delaware
corporation and a wholly-owned subsidiary of Parent ("Merger Sub"), and
FirstSense Software, Inc., a Delaware corporation (the "Company").

                                    RECITALS

         A. Parent, Merger Sub and the Company intend to effect a merger (the
"Merger") of Merger Sub with and into the Company in accordance with this
Agreement and the Delaware General Corporation Law ("Delaware Law"). Upon
consummation of the Merger, Merger Sub will cease to exist, and the Company will
become a wholly-owned subsidiary of Parent.

         B. It is intended that the Merger qualify as a tax-free reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"). For accounting purposes, it is intended that the Merger be
treated as a "pooling of interests."

         C. The Board of Directors of the Company has unanimously (i) determined
that the Merger is fair to, and in the best interests of, the Company and its
stockholders, (ii) approved this Agreement, the Escrow Agreement, the Merger and
the other transactions contemplated by this Agreement and (iii) resolved to
recommend to the stockholders of the Company that they adopt and approve this
Agreement, the Escrow Agreement, the Merger and the transactions contemplated
hereby.

         D. The respective Boards of Directors of Parent and Merger Sub have
approved this Agreement and the Merger.

         E. Concurrently with the execution of this Agreement, and as a
condition and inducement to Parent's and Merger Sub's willingness to enter into
this Agreement, each of the stockholders of the Company listed on Exhibit A
hereto is entering into a Voting Agreement substantially in the form attached
hereto as Exhibit A-1, and each of the affiliate stockholders of the Company
listed on Schedule 2.28 hereto is entering into an Affiliate Agreement
substantially in the form attached hereto as Exhibit B.

         NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby the parties hereto agree as follows:

                                    ARTICLE I

                                   THE MERGER

         1.1      The Merger. At the Effective Time (as defined in Section 1.2),
and subject to and upon the terms and conditions of this Agreement and Delaware
Law, Merger Sub shall be

   7

merged with and into the Company, the separate corporate existence of Merger Sub
shall cease and the Company shall continue as the surviving corporation and as a
wholly-owned subsidiary of Parent. The Company as the surviving corporation
after the Merger is hereinafter sometimes referred to as the "Surviving
Corporation."

         1.2      Effective Time. Unless this Agreement is earlier terminated
pursuant to Section 9.1, the closing of the Merger (the "Closing") will take
place as promptly as practicable, but no later than three (3) business days,
following satisfaction or waiver of the conditions set forth in Article VII, at
the offices of Testa, Hurwitz & Thibeault, LLP, 125 High Street, Boston, MA
02110, unless another place or time is agreed to by Parent and the Company. The
date upon which the Closing actually occurs is herein referred to as the
"Closing Date." On the Closing Date, the parties hereto shall cause the Merger
to be consummated by filing a Certificate of Merger, in substantially the form
attached hereto as Exhibit C (the "Certificate of Merger"), and the required
officers' certificates, with the Secretary of State of the State of Delaware, in
accordance with the relevant provisions of Delaware Law (the date and time of
such filing being referred to herein as the "Effective Time").

         1.3      Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in this Agreement, the Certificate of Merger and the
applicable provisions of Delaware Law. Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, all the rights, property,
powers, privileges and franchises of the Company and Merger Sub shall vest in
the Surviving Corporation, and all debts, liabilities and duties of the Company
and Merger Sub shall become the debts, liabilities and duties of the Surviving
Corporation.

         1.4      Articles of Incorporation; By-Laws.

                  (a)      Unless otherwise determined by Parent prior to the
Effective Time, at the Effective Time, the Certificate of Incorporation of the
Surviving Corporation shall be amended and restated in its entirety as set forth
in the Certificate of Merger until thereafter amended as provided by law and
such Certificate of Incorporation.

                  (b)      Unless otherwise determined by Parent prior to the
Effective Time, at the Effective Time, the By-Laws of the Surviving Corporation
shall be amended and restated in their entirety as set forth in the Certificate
of Merger until thereafter amended.

         1.5      Directors and Officers. The directors of Merger Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and By-Laws of the Surviving Corporation. The officers of Merger
Sub immediately prior to the Effective Time shall be the initial officers of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and By-Laws of the Surviving Corporation.

         1.6      Merger Consideration; Effect on Capital Stock.

                  (a)      Merger Consideration; Conversion. The aggregate
number of shares of common stock of Parent, par value $.01 per share ("Parent
Common Stock"), to be issued


                                      -2-
   8

(including Parent Common Stock to be reserved for issuance upon exercise of any
Company Options (as defined in Section 1.6(e)) in exchange for the acquisition
by Parent of all outstanding capital stock of the Company ("Company Capital
Stock"), the assumption by Parent of all outstanding Company Options as provided
in Section 1.6(e), and the exchange for all Unvested Preferred Options (as
defined) shall be 1,940,000 shares of Parent Common Stock ("Aggregate Share
Number"). No adjustment shall be made in the Aggregate Share Number as a result
of any proceeds received by the Company from the date hereof to the Closing Date
pursuant to the exercise of any Company Options or outstanding warrants to
purchase Company Capital Stock. Subject to the terms and conditions of this
Agreement, including without limitation Section 1.6(c) and Article VIII hereof,
at the Effective Time, by virtue of the Merger and without any action on the
part of Merger Sub, the Company, the holders of any shares of Company Capital
Stock or the holders of any capital stock of Merger Sub, each share of common
stock of the Company, par value $.01 per share ("Company Common Stock"), issued
and outstanding immediately prior to the Effective Time shall be converted into
the right to receive the Applicable Fraction of a share of Parent Common Stock.
For purposes of this Agreement, the term "Applicable Fraction" shall mean (i)
1,940,000 divided by (ii) the Fully Diluted Company Share Number as of
immediately prior to the Effective Time. For purposes of this Agreement, the
term "Fully Diluted Company Share Number" shall mean, as of the date of
determination thereof, the sum of (A) the aggregate number of shares of Company
Common Stock then issued and outstanding and (B) the aggregate number of shares
of Company Common Stock issuable under, or otherwise subject to, any Purchase
Rights then outstanding (including any Purchase Rights that are unvested or are
otherwise not then exercisable).

                  (b)      Stock Restrictions. If any shares of Company Common
Stock issued and outstanding immediately prior to the Effective Time are
unvested or are subject to a repurchase option, risk of forfeiture or other
condition under any applicable restricted stock purchase agreement or other
agreement with the Company, then the shares of Parent Common Stock issued in
exchange for such shares of Company Common Stock will also be unvested and
subject to the same repurchase option, risk of forfeiture or other condition,
and the certificates representing such shares of Parent Common Stock may
accordingly be marked with appropriate legends in the discretion of Parent.

                  (c)      Escrow. Ten percent (10%) of the Parent Common Stock
to be issued in exchange for the outstanding Company Common Stock in the Merger
(the "Escrow Shares") (none of which Escrow Shares shall be unvested, subject to
any right of repurchase, risk of forfeiture or other condition in favor of the
Company or the Surviving Corporation) shall be held in escrow pursuant to the
Escrow Agreement to reimburse Parent and its Affiliates (including the Surviving
Corporation) for any Losses (as defined in Section 8.2(a) hereof) incurred in
connection with this Agreement and the transactions contemplated hereby. The
Escrow Shares will be withheld on a pro rata basis among the holders of Company
Common Stock. The exact number of Escrow Shares held for the account of each
holder of Company Common Stock will be set forth in the Escrow Schedule as
provided in Section 8.2(a). The delivery of the Escrow Shares will be made on
behalf of the holders of Company Common Stock in accordance with the provisions
hereof, with the same force and effect as if such shares had been delivered by
Parent


                                      -3-
   9

directly to such holders and subsequently delivered by such holders to the
Escrow Agent (as defined in Section 8.2(a)).

                  (d)      Cancellation of Parent-Owned and Company-Owned Stock.
At the Effective Time, by virtue of the Merger and without any action on the
part of Merger Sub, the Company, the holders of any shares of Company Capital
Stock, or the holders of any capital stock of Merger Sub, each share of Company
Capital Stock owned by Merger Sub, Parent, the Company or any direct or indirect
wholly-owned subsidiary of Parent or of the Company immediately prior to the
Effective Time shall be canceled and extinguished without any conversion thereof
and no consideration shall be delivered in exchange therefor.

                  (e)      Stock Options. At the Effective Time, the Company's
1997 Stock Incentive Plan and 1996 Equity Incentive Stock Plan, each as amended
to date (the "Option Plans"), and all options to purchase Company Common Stock
then outstanding under the Option Plans (other than the Unvested Preferred
Options), shall be assumed by Parent in accordance with the following
provisions:

                           (i)      At the Effective Time, each outstanding
option to purchase shares of Company Common Stock issued under the Option Plans
(each a "Company Option"), whether vested or unvested, shall be, in connection
with the Merger, assumed by Parent. Parent and the Company will take all action
necessary to cause the assumption by Parent as of the Effective Time of the
Option Plans and all of the Company Options set forth on Schedule 2.3(b) or
granted on or after the date hereof with the consent of Parent and, in each
case, outstanding as of the Effective Time. The Company will take all corporate
action necessary to effect, without the consent or cooperation of the holders of
Company Options, such assumption by Parent and the conversion of the Company
Options into options to purchase shares of Parent Common Stock as set forth
herein. Each Company Option so assumed by Parent under this Agreement shall
continue to have, and be subject to, the same terms and conditions set forth in
the relevant Option Plan and/or as provided in the respective option agreements
governing such Company Option immediately prior to the Effective Time, except
that (A) such Company Option shall be exercisable for that number of whole
shares of Parent Common Stock equal to the product of the number of shares of
Company Common Stock that were issuable upon exercise of such Company Option
immediately prior to the Effective Time multiplied by the Applicable Fraction,
rounded down (in the case of Company Options granted under the Option Plans) to
the nearest whole number of shares of Parent Common Stock and (B) the per share
exercise price for the shares of Parent Common Stock issuable upon exercise of
such assumed Company Option shall be equal to the quotient determined by
dividing the exercise price per share of Company Common Stock at which such
Company Option was exercisable immediately prior to the Effective Time by the
Applicable Fraction, rounded up to the nearest whole cent.

                           (ii)     It is the intention of the parties that the
Company Options assumed by Parent pursuant to this Section 1.6(e) qualify
following the Effective Time as incentive stock options as defined in Section
422 of the Code to the extent the Company Options qualified as incentive stock
options immediately prior to the Effective Time.


                                      -4-
   10

                           (iii)   Promptly following the Effective Time, Parent
will issue to each holder of an outstanding Company Option a document evidencing
the foregoing assumption of such Company Option by Parent.

                           (iv)     Notwithstanding anything to the contrary
contained herein, each of Albert Briner, James Kelly and Sekhar Muddana, as
holders of options to purchase both Company Common Stock and Series A Preferred
Stock of the Company, shall have delivered concurrently with the signing of this
Agreement by the Company the Option Exercise Agreement (the "Option Exercise
Agreement") in the form of Exhibit A-2 hereto and the Unvested Preferred Options
(as defined in Exhibit A-2) shall be treated in the Merger as specified in the
Option Exercise Agreement.

                  (f)      Capital Stock of Merger Sub. At the Effective Time,
by virtue of the Merger and without any action on the part of Merger Sub, the
Company, the holders of any shares of Company Capital Stock or the holders of
any capital stock of Merger Sub, each share of Common Stock of Merger Sub issued
and outstanding immediately prior to the Effective Time shall be converted into
and become one validly issued, fully paid and nonassessable share of Common
Stock of the Surviving Corporation. Each stock certificate of Merger Sub
evidencing ownership of any such shares shall continue to evidence ownership of
such shares of capital stock of the Surviving Corporation.

                  (g)      Adjustments. In the event of any stock split, reverse
split, stock dividend (including any dividend or distribution of securities
convertible into Parent Common Stock or Company Capital Stock), reorganization,
recapitalization or other like change with respect to Parent Common Stock or
Company Capital Stock occurring after the date hereof and prior to the Effective
Time, appropriate adjustments will be made to the number of shares of Parent
Common Stock issuable in exchange for shares of Company Capital Stock and upon
the exercise of Company Options.

                  (h)      Fractional Shares. No fraction of a share of Parent
Common Stock will be issued, but in lieu thereof, each holder of shares of
Company Common Stock who would otherwise be entitled to a fraction of a share of
Parent Common Stock (after aggregating all fractional shares of Parent Common
Stock to be received by such holder) shall be entitled to receive from Parent an
amount of cash (rounded to the nearest whole cent) equal to the product of (i)
such fraction, multiplied by (ii) the average of the closing prices per share of
Parent Common Stock (as quoted on the Nasdaq National Market and reported in the
Wall Street Journal) for the ten (10) consecutive trading days ending
immediately prior to the Closing Date (hereinafter referred to as the
"Designated Parent Stock Price").

         1.7      Dissenting Shares.

                  (a)      Notwithstanding any provision of this Agreement to
the contrary, any shares of Company Common Stock held by a holder who has
demanded and perfected appraisal or dissenters' rights for such shares in
accordance with Delaware Law and who, as of the Effective Time, has not
effectively withdrawn or lost such appraisal or dissenters' rights


                                      -5-
   11

("Dissenting Shares"), shall not be converted into or represent a right to
receive Parent Common Stock (and cash in lieu of fractional shares of Parent
Common Stock) pursuant to Section 1.6, but the holder thereof shall only be
entitled to such rights as are granted by Delaware Law.

                  (b)      Notwithstanding the provisions of subsection (a), if
any holder of shares of Company Common Stock who demands appraisal of such
shares under Delaware Law shall effectively withdraw or lose (through failure to
perfect or otherwise) the right to appraisal, then, as of the later of the
Effective Time and the occurrence of such event, such holder's shares shall
automatically be converted into and represent only the right to receive Parent
Common Stock and cash in lieu of fractional shares of Parent Common Stock as
provided in Section 1.6, without interest thereon, upon surrender of the
certificate representing such shares in accordance with Section 1.8.

                  (c)      The Company shall give Parent (i) prompt notice of
any written demands for appraisal of any shares of Company Common Stock,
withdrawals of such demands, and any other instruments served pursuant to
Delaware Law and received by the Company and (ii) the opportunity to participate
in all negotiations and proceedings with respect to demands for appraisal under
Delaware Law. The Company shall not, except with the prior written consent of
Parent, voluntarily make any payment with respect to any demands for appraisal
of Company Common Stock or offer to settle or settle any such demands.

         1.8      Surrender of Certificates.

                  (a)      Exchange Agent. Prior to the Effective Time, Parent
shall designate Boston Equiserve (or if Boston Equiserve is not willing or able
to so act, another United States bank or trust company reasonably acceptable to
the Company) to act as exchange agent (the "Exchange Agent") in the Merger.

                  (b)      Parent to Provide Common Stock. Promptly after the
Effective Time, Parent shall make available to the Exchange Agent for exchange
in accordance with this Article I, the aggregate amount of cash and the
aggregate number of shares of Parent Common Stock payable or issuable pursuant
to Section 1.6 in exchange for outstanding shares of Company Common Stock;
provided, however, that, on behalf of the holders of Company Common Stock, and
pursuant to the Escrow Agreement, Parent shall deposit the Escrow Shares with
the Escrow Agent out of the aggregate number of shares of Parent Common Stock
otherwise issuable pursuant to Section 1.6.

                  (c)      Exchange Procedures. Promptly after the Effective
Time, the Surviving Corporation shall cause to be mailed to each holder of
record of a certificate or certificates (the "Certificates") which immediately
prior to the Effective Time represented outstanding shares of Company Common
Stock (including certificates for shares of Preferred Stock which have been
converted to shares of Company Common Stock but for which new certificates have
not been issued) whose shares were converted into the right to receive shares of
Parent Common Stock pursuant to Section 1.6, (i) a form of letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon delivery of the


                                      -6-
   12

Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Parent may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing shares of Parent Common Stock. Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by Parent, together with such letter of transmittal, duly completed
and validly executed in accordance with the instructions thereto, and such other
customary documents as may be required pursuant to such instructions, the holder
of such Certificate shall be entitled to receive in exchange therefor a
certificate representing the number of whole shares of Parent Common Stock (less
the number of shares of Parent Common Stock to be deposited with the Escrow
Agent on such holder's behalf pursuant to Section 1.6 and Article VIII hereof),
plus cash in lieu of fractional shares in accordance with Section 1.6, to which
such holder is entitled pursuant to Section 1.6, and the Certificate so
surrendered shall forthwith be canceled. As soon as practicable after the
Effective Time, and subject to and in accordance with the provisions of Article
VIII hereof and the Escrow Agreement, Parent shall cause to be delivered to the
Escrow Agent, on behalf of the holders of Certificates, a certificate or
certificates representing the Escrow Shares which shall be registered in the
name of the Escrow Agent. Such shares shall be beneficially owned by the holders
on whose behalf such shares were deposited with the Escrow Agent as set forth in
Section 8.2 and the Escrow Agreement and shall be available to reimburse Parent
as provided in Article VIII and the Escrow Agreement. Until so surrendered, each
outstanding Certificate that, prior to the Effective Time, represented shares of
Company Common Stock (including Certificates for shares of Preferred Stock which
have been converted to shares of Company Common Stock but for which new
certificates have not been issued) will be deemed from and after the Effective
Time, for all corporate purposes, other than the payment of dividends, to
evidence the ownership of the number of full shares of Parent Common Stock into
which such shares of Company Common Stock shall have been so converted and the
right to receive an amount in cash in lieu of the issuance of any fractional
shares in accordance with Section 1.6.

                  (d)      Distributions With Respect to Unexchanged Shares. No
dividends or other distributions declared or made after the Effective Time with
respect to Parent Common Stock with a record date after the Effective Time will
be paid to the holder of any unsurrendered Certificate with respect to the
shares of Parent Common Stock represented thereby until the holder of record of
such Certificate shall surrender such Certificate. Subject to applicable law,
following surrender of any such Certificate, there shall be paid to the record
holder of the certificates representing whole shares of Parent Common Stock
issued in exchange therefor, without interest, at the time of such surrender,
the amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of Parent
Common Stock.

                  (e)      Transfers of Ownership. If any certificate for shares
of Parent Common 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 issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the Person
requesting such exchange will have paid to Parent or any agent designated by it
any transfer or other taxes required by reason of the issuance of a certificate
for shares of Parent


                                      -7-
   13

Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.

                  (f)      No Liability. Notwithstanding anything to the
contrary in this Section 1.8, none of the Exchange Agent, Parent, the Surviving
Corporation or any party hereto shall be liable to a holder of shares of Parent
Common Stock or Company Capital Stock for any amount properly paid to a public
official pursuant to any applicable abandoned property, escheat or similar law.

         1.9      No Further Ownership Rights in Company Stock. All shares of
Parent Common Stock issued by Parent upon the surrender for exchange of shares
of Company Common Stock in accordance with the terms hereof (including any cash
paid in respect thereof) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Company Common Stock,
and there shall be no further registration of transfers on the records of the
Surviving Corporation of shares of Company Capital Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Article I.

         1.10     Lost, Stolen or Destroyed Certificates. In the event any
certificates evidencing shares of Company Capital Stock shall have been lost,
stolen or destroyed, the Exchange Agent shall issue in exchange in lieu of such
lost, stolen or destroyed certificates, upon the making of an affidavit of that
fact by the holder thereof, such shares of Parent Common Stock and cash for
fractional shares, if any, as may be required pursuant to Section 1.6; provided,
however, that Parent may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
certificates to deliver a bond in such sum as it may direct as indemnity against
any claim that may be made against Parent, the Surviving Corporation or the
Exchange Agent with respect to the certificates alleged to have been lost,
stolen or destroyed.

         1.11     Tax and Accounting Consequences. It is intended by the parties
hereto that the Merger shall (i) constitute a reorganization within the meaning
of Section 368 of the Code (and this Agreement is intended to constitute a plan
of reorganization for purposes of Section 368 of the Code) and (ii) qualify for
accounting treatment as a "pooling of interests."

         1.12     Taking of Necessary Action; Further Action. If, at any time
after the Effective Time, any such further action is necessary or desirable to
carry out the purposes of this Agreement and to vest the Surviving Corporation
with full right, title and possession to all assets, property, rights,
privileges, powers and franchises of the Company and Merger Sub, the officers
and directors of the Company and Merger Sub are fully authorized in the name of
their respective corporations or otherwise to take, and will take, all such
lawful and necessary action.

                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company hereby represents and warrants to each of Parent and Merger
Sub as follows:

         2.1      Organization of the Company. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. The Company has the corporate power to own, lease and operate its
properties and to carry on its business as now being conducted. The Company is
duly qualified or licensed to do business and is in good standing as a foreign
corporation in each jurisdiction in which the failure to be so qualified or
licensed has had or could be reasonably expected to have a Material Adverse
Effect (as defined below) on the Company. For purposes of this Agreement, a
"Material Adverse Effect" shall mean, with respect to Parent on the one hand and
the Company on the other hand, the result of one or more events, occurrences,
changes or effects which, individually or in the aggregate, has had or could be
reasonably expected to have a material adverse effect or impact on the business,
assets (including intangible assets), results of operations or financial
condition of such party and its subsidiaries, taken as a whole, or on such
party's ability to consummate the transactions contemplated hereby. The Company
has delivered a true and correct copy of its Certificate of Incorporation and
By-Laws, each as amended to date, to Parent.

         2.2      Subsidiaries.

                  (a)      Except as set forth on Schedule 2.2 of the written
disclosure schedules delivered by the Company to Parent concurrently with the
execution of this Agreement (the "Company Schedules"), the Company does not
directly or indirectly own any equity or similar interest in, or any interest
convertible into or exchangeable or exercisable for, any equity or similar
interest in, any Person. The Persons set forth on Schedule 2.2 of the Company
Schedules are sometimes herein referred to individually as a "Subsidiary" and
collectively as the "Subsidiaries."

                  (b)      Each Subsidiary is a corporation duly organized,
validly existing and in good standing under the laws of its jurisdiction of
incorporation or organization (to the extent such concepts are applicable), and
has the corporate power to own, lease and operate its properties and to carry on
its business as now being conducted. Each Subsidiary is duly qualified or
licensed to do business and is in good standing as a foreign corporation in each
jurisdiction in which the failure to be so qualified or licensed has had or
could be reasonably expected to have a Material Adverse Effect on the Company.
The Company has delivered a true and correct copy of the Certificate of
Incorporation and By-Laws (or comparable documents) of each of the Subsidiaries,
each as amended to date, to Parent.

                  (c)      All of the outstanding capital stock of, or other
ownership interests in, each Subsidiary is owned by the Company, directly or
indirectly, free and clear of any Lien and free of any other limitation or
restriction (including any restriction on the right to vote, sell or


                                      -9-
   15

otherwise dispose of such capital stock or other ownership interests). There are
no outstanding (i) securities of the Company or any Subsidiary convertible into
or exchangeable for shares of capital stock or other voting securities or
ownership interests in any Subsidiary, or (ii) options or other rights to
acquire from the Company or any Subsidiary, or to cause the Company or any
Subsidiary to issue, any capital stock, voting securities or other ownership
interests in, any Subsidiary (the items in clauses (i) and (ii) being referred
to collectively as the "Subsidiary Securities"). There are no outstanding
obligations of the Company or any Subsidiary to repurchase, redeem or otherwise
acquire any outstanding Subsidiary Securities.

         2.3      Company Capital Structure.

                  (a)      The authorized capital stock of the Company consists
of (i) 20,000,000 shares of Company Common Stock, of which 2,696,667 shares are
issued and outstanding, and (ii) 11,100,000 shares of Preferred Stock, par value
$.01 per share (the "Preferred Stock"), of which (y) 5,500,000 shares have been
designated Series A Preferred Stock (the "Series A Preferred Stock") and of
which 5,471,465 shares are issued and outstanding, (z) 2,920,000 shares have
been designated Series B Preferred Stock (the "Series B Preferred Stock"), and
of which 2,800,000 shares are issued and outstanding. No shares of Company
Common Stock or Preferred Stock are held in the Company's treasury. The Company
Common Stock and Preferred Stock is held of record by the Persons, with the
addresses of record and in the amounts set forth on Schedule 2.3(a) of the
Company Schedules. There are not more than 35 holders of record of Company
Capital Stock that are not accredited investors (as that term is defined in
Regulation D promulgated under the Securities Act). All of the outstanding
shares of Preferred Stock will have converted into shares of Company Common
Stock on a one share of Preferred Stock for one share of Company Common Stock
basis prior to the Effective Time (the "Conversion"). As of the Effective Time,
there will be no issued and outstanding shares of Preferred Stock or options to
purchase Preferred Stock other than the Unvested Preferred Options. The
Conversion was properly authorized by all necessary action of the Company and
the holders of Preferred Stock, including any actions required pursuant to the
Company's Certificate of Incorporation, By-Laws and/or agreements and
instruments relating to the Preferred Stock. All of the outstanding (x) options
to purchase Series A Preferred Stock and Series B Preferred Stock (the
"Preferred Options") and (y) warrants to purchase Series B Preferred Stock (the
"Warrants") shall have been exercised at or prior to the Effective Time other
than the Unvested Preferred Options. The Warrants are exercisable for an
aggregate of 120,000 shares of Series B Preferred Stock. The Preferred Options
are exercisable for an aggregate of 28,535 shares of Series A Preferred Stock.
As of the Effective time, there will be no outstanding Warrants or Preferred
Options other than the Unvested Preferred Options. Schedule 2.3(a) of the
Company Schedules also indicates for each Company stockholder whether any shares
of Company Common Stock or Preferred Stock held by such stockholder are subject
to a repurchase right in favor of the Company, the lapsing schedule for any such
restricted shares, including the extent to which any such repurchase right has
lapsed as of the date of this Agreement and whether (and to what extent) the
lapsing will be accelerated by the transactions contemplated by this Agreement.
All outstanding shares of Company Common Stock and Preferred Stock are duly
authorized, validly issued, fully paid and non-assessable and not subject to
preemptive rights created by statute, the Certificate of Incorporation or
By-Laws of the Company or any agreement to which the


                                      -10-
   16

Company is a party or by which it is bound. All preferential rights of the
Preferred Stock in connection with the sale of substantially all of the assets
of the Company or a merger involving the Company are set forth in the
Certificate of Incorporation of the Company. All issued and outstanding shares
of Company Common Stock and Preferred Stock have been offered, sold and
delivered by the Company in compliance with applicable federal and state
securities laws. There are no shares of Company Capital Stock other than as set
forth on Schedule 2.3(a) of the Company Schedules. The optionholders executing
the Option Exercise Agreement have properly executed such agreements and do not
have the right to receive any Parent Common Stock in the Merger other than as
specified in such agreements.

                  (b)      The Company has reserved 1,930,288 shares of Company
Common Stock for issuance to employees and consultants pursuant to the Option
Plans, of which (i) 1,813,278 shares of Company Common Stock are subject to
outstanding, unexercised options, (ii) none of the shares are subject to
outstanding unexercised Purchase Rights (as defined below) and (iii) 62,899
shares of Company Common Stock remain available for future grant. Schedule
2.3(b) of the Company Schedules sets forth each outstanding Company Option,
including the name of the holder of such option, the domicile address of such
holder, an indication of whether such holder is an employee of the Company, the
date of grant or issuance of such option, the number of shares of Common Stock
subject to such option, the exercise price of such option and the vesting
schedule for such option, including the extent vested to the date of this
Agreement and whether and to what extent the exercisability of such option will
be accelerated and become exercisable as a result of the transactions
contemplated by this Agreement. Except for the Company Options, the Preferred
Stock and the agreements set forth on Schedule 2.3(b) of the Company Schedules,
there are no options, warrants, calls, rights, exchangeable or convertible
securities, commitments or agreements of any character, written or oral, to
which the Company is a party or by which it is bound obligating the Company to
(i) issue, deliver, sell, repurchase or redeem, or cause to be issued,
delivered, sold, repurchased or redeemed, any Company Common Stock or Preferred
Stock or (ii) grant, extend, accelerate the vesting of, change the price of,
otherwise amend or enter into any such option, warrant, call, right,
exchangeable or convertible securities, commitment or agreement (collectively,
"Purchase Rights"). All issued and outstanding Company Options have been
offered, issued and delivered in compliance with applicable federal and state
securities laws. The holders of Company Options have been or will be given, or
shall have properly waived, any required notice prior to the Merger. As a result
of the Merger, Parent will be the record and sole beneficial owner of all
Company Capital Stock and rights to acquire or receive Company Capital Stock.
Upon the assumption by Parent of the outstanding Company Options as set forth in
Section 1.6(e), all of such Company Options shall be exercisable solely for
shares of Parent Common Stock as set forth in Section 1.6(e). The assumption of
the Company Options and the Option Plans by Parent as set forth in Section
1.6(e) does not conflict with or violate the provisions of any Option Plan or
any stock option or other agreement or instrument relating to or governing any
Company Option and no consent or approval of, or notice to, any Person is
required in connection with such assumption.

         2.4      Authority. The Company has all requisite corporate power and
authority to execute and deliver this Agreement and the Escrow Agreement and,
subject only to the requisite approval of the Merger and the terms of this
Agreement and the Escrow Agreement by the


                                      -11-
   17

Company's stockholders, to perform its obligations hereunder and thereunder and
to consummate the transactions contemplated hereby and thereby. The only vote
required of the Company's stockholders to duly approve the Merger and the terms
of this Agreement and the Escrow Agreement is the affirmative vote at a meeting
duly called and held for such purpose of such number of shares as would
constitute as of the record date for such meeting (a) a majority of the
outstanding shares of Company Common Stock, (b) a majority of the outstanding
shares of Company Common Stock and Preferred Stock, voting together as a single
class (with each share of Preferred Stock being entitled to a number of votes
equal to the number of whole shares of Company Common Stock into which such
share of Preferred Stock could be converted on the record date for the vote,
which is one share of Company Common Stock for each share of Preferred Stock)
and (c) two-thirds of the outstanding shares of Preferred Stock. No vote or
other action is required to be taken by or on behalf of the Subsidiaries to duly
approve the Merger or the terms of this Agreement and the Escrow Agreement. The
execution and delivery of this Agreement and the Escrow Agreement and, subject
only to the approval of the Merger and this Agreement and the Escrow Agreement
by the Company's stockholders, the consummation of the transactions contemplated
hereby and thereby have been duly authorized by all necessary corporate action
on the part of the Company. The Company's Board of Directors has unanimously (i)
determined that the Merger is fair to, and in the best interests of, the Company
and its stockholders, (ii) approved this Agreement, the Merger, the Escrow
Agreement and the other transactions contemplated by this Agreement and the
Escrow Agreement and (iii) resolved to recommend to the stockholders of the
Company that they adopt and approve this Agreement, the Escrow Agreement the
Merger and all the transactions contemplated hereby and thereby. This Agreement
has been duly executed and delivered by the Company and constitutes the legal,
valid and binding obligation of the Company, enforceable in accordance with its
terms, except that the enforcement hereof may be limited by (a) bankruptcy,
insolvency, reorganization, moratorium or other similar laws now or hereafter in
effect relating to creditors' rights generally and (b) general principles of
equity (regardless of whether enforceability is considered in a proceeding at
law or in equity). The Company has complied with, or has taken all actions
necessary to render inapplicable, any state takeover statute or similar statute
or regulation applicable to the Merger, this Agreement, the Escrow Agreement and
the transactions contemplated hereby and thereby.

         2.5      No Conflict. Except as set forth on Schedule 2.5 of the
Company Schedules, the execution and delivery of this Agreement and the Escrow
Agreement by the Company does not, and the compliance with and performance of
this Agreement and the Escrow Agreement and the consummation of the transactions
contemplated hereby and thereby by the Company will not, conflict with, or
result in any violation of, or default under (with or without notice or lapse of
time, or both), or give rise to a right of termination, cancellation or
acceleration of any obligation or loss of any benefit under (any such event, a
"Conflict") (i) any provision of the Certificate of Incorporation or By-Laws of
the Company or any Subsidiary or (ii) any Contract, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to the Company, any
Subsidiary or any of its respective properties or assets, except for any
conflict that would not have a Material Adverse Effect on the Company.


                                      -12-
   18

         2.6      Consents. No consent, waiver, approval, order or authorization
of, or registration, declaration or filing with, or notice to, any court,
administrative agency or commission or other federal, state, county, local or
foreign governmental authority, instrumentality, agency or commission
("Governmental Entity") or any third party (so as not to trigger any Conflict),
is required by or with respect to the Company or any Subsidiary in connection
with the execution and delivery of this Agreement and the Escrow Agreement or
the consummation of the transactions contemplated hereby and thereby, except for
(i) the filing of the Certificate of Merger and required certificates with the
Delaware Secretary of State and (ii) such other consents, waivers,
authorizations, filings, approvals and registrations which are set forth on
Schedule 2.6 of the Company Schedules.

         2.7      Company Financial Statements. The Company has previously
delivered to Parent the audited consolidated balance sheets of the Company as of
December 31, 1998 and December 31, 1997 and the related audited consolidated
statements of operations and changes in stockholders' equity and cash flows for
each of the years ended December 31, 1998 and December 31, 1997 (the "Company
Audited Financial Statements"). The Company Audited Financial Statements present
fairly, in all material respects, the financial position of the Company and its
Subsidiaries as of the dates thereof and their results of operations and changes
in stockholders' equity and cash flows for the periods then ended in conformity
with generally accepted accounting principles ("GAAP") applied on a consistent
basis throughout the periods then ended. The Company has also previously
delivered to Parent the unaudited consolidated statement of operations of the
Company and its Subsidiaries for the year ended December 31, 1999 and the
unaudited consolidated balance sheet of the Company and its Subsidiaries as of
December 31, 1999 (the "Balance Sheet Date") (collectively, the "Company
Unaudited Financial Statements"). The consolidated balance sheet included in the
Company Unaudited Financial Statements (including any related notes) (the
"Company Balance Sheet") presents fairly, in all material respects, the
financial position of the Company and its Subsidiaries as of the Balance Sheet
Date and the consolidated statement of operations included in the Company

   22

any Tax. No power of attorney has been granted by the Company or its

(collectively, "Liens") on the assets of the Company or any Subsidiary relating
to or attributable to Taxes.

                           (vii)    There is no reasonable basis for the
assertion of any claim relating or attributable to Taxes which, if adversely
determined, would result in any Lien on the assets of the Company or any
Subsidiary.

                           (viii)   None of the assets of the Company or any
Subsidiary are treated as "tax-exempt use property" within the meaning of

                                      -19-
   25

operations of the Company, nor the operations of any Subsidiary, on such real
property, nor to the knowledge of the Company, such real property, including

personal and mixed, used or held for use in its respective business, free and
clear of any Liens, except as reflected in the Company Audited Financial
Statements and such Liens, if any, which are not material in character, amount

Subsidiary are (i) adequate for the conduct of the business of the Company and
the Subsidiaries as currently conducted and as proposed to be conducted and (ii)
in good operating condition, subject to normal wear and tear, and reasonably fit
and usable for the purposes for which they are being used, except where a
failure to be in such condition has not had and could not be reasonably expected
to have a Material Adverse Effect on the Company.

                  (d)      Neither the Company nor any Subsidiary has sold or
otherwise released for distribution any of its respective customer files and
other customer information relating to the current and former customers of the
Company and the Subsidiaries (the "Company Customer Information"). Except for
information as provided to sales representatives (which information is subject
to a customary non-disclosure agreement), no Person other than the Company and
the Subsidiaries possesses any claims or rights with respect to use of the
Company Customer Information.

         2.13     Governmental Authorization. Schedule 2.13 of the Company
Schedules accurately lists each consent, license, permit, grant or other
authorization issued to the Company or any Subsidiary by a Governmental Entity
(i) pursuant to which the Company or any Subsidiary currently operates or holds
any interest in any of its respective properties or (ii) which is required for
the operation of its respective business or the holding of any such interest
(herein collectively called "Company Authorizations"). The Company
Authorizations are in full force and effect and constitute all Company
Authorizations required to permit the Company and the Subsidiaries to operate or
conduct their businesses or hold any interest in their respective properties or
assets except for Company Authorizations the absence or invalidity of which has
not had and could not be reasonably expected to have a Material Adverse Effect
on the Company.

2.14(b) of the Company Schedules or Schedule 2.14(c) of the Company Schedules,
nor entitle any other party to any such license, sublicense or agreement to
terminate or modify such license, sublicense or agreement.

                  (e)      Neither the Company nor any Subsidiary has been sued
or charged as a defendant in any claim, suit, action, or proceeding which
involves a claim of infringement of any Intellectual Property of any third party
and which has not been finally terminated prior to the date hereof nor does the
Company have any knowledge of any such charge or claim or any infringement
liability with respect to, or infringement or violation by, the Company or any
Subsidiary of any Intellectual Property of another. No Company Intellectual
Property or product of the Company or any Subsidiary is subject to any
outstanding decree, order, judgment or stipulation restricting in any manner the
licensing of products by the Company or any Subsidiary.

                  (f)      Each item of Company Registered Intellectual Property
is valid and subsisting. All necessary registration, maintenance and renewal
fees currently due in connection with such Company Registered Intellectual
Property have been made and all necessary documents, recordations and
certificates in connection with such Company Registered Intellectual Property
have been filed with the relevant patent, copyright, trademark or other
authorities in the United States or foreign jurisdictions, as the case may be,
for the purposes of maintaining such Company Registered Intellectual Property.

                  (g)      The Company is the sole and exclusive owner or
licensee of, with all right, title, and interest in and to each item of Company
Intellectual Property, free and clear of any Lien, and has sole and exclusive
rights (and neither the Company nor any Subsidiary is contractually obligated to
pay any compensation (other than licensing fees and royalties set forth in the
applicable license) to any third party in respect thereof) to the use thereof or
the material


                                      -22-
   28

covered thereby in connection with the services or products in respect of which
the Company Intellectual Property is being used. Except as set forth on Schedule
2.14(g) of the Company Schedules, no Company Intellectual Property is subject to
any restrictions with respect to its use, modification or distribution. Neither
the Company nor any Subsidiary uses nor is licensed to use, and none of its
respective products include or incorporate, (i) any software distributed free of
charge on a trial basis for which a paid license would be required and has not
been obtained for commercial distribution or (ii) any software whose ownership
has been retained by a third party who controls its distribution.

                  (h)      To the extent that any material Company Intellectual
Property has been developed or created by a third party for the Company or any
Subsidiary, the Company or such Subsidiary has a written agreement with such
third party with respect thereto, and the Company or such Subsidiary thereby
either (i) has obtained ownership of, and is the exclusive owner of, or (ii) has
obtained a license (sufficient for the conduct of its business as currently
conducted and as proposed to be conducted) to all such third party's
Intellectual Property in such work, material or invention by operation of law or
by valid assignment.

                  (i)      Neither the Company nor any Subsidiary has
transferred ownership of, or granted any exclusive license with respect to, any
Intellectual Property that is or was material Company Intellectual Property, to
any third party.

                  (j)      All contracts, licenses and agreements relating to
the Company Intellectual Property are in full force and effect. Each of the
Company and the Subsidiaries is in material compliance with, and has not
breached any term of such contracts, licenses and agreements and, to the
knowledge of the Company, all other parties to such contracts, licenses and
agreements are in compliance with, and have not breached any term of, such
contracts, licenses and agreements. Following the Closing Date, the Surviving
Corporation will be permitted to exercise all of the Company's and the
Subsidiaries' rights under such contracts, licenses and agreements to the same
extent the Company and the Subsidiaries would have been able to had the
transactions contemplated by this Agreement not occurred and without the payment
of any additional amounts or consideration other than ongoing fees, royalties or
payments which the Company or any Subsidiary would otherwise be required to pay.

                  (k)      No claims with respect to Company Intellectual
Property have been asserted or, to the Company's knowledge, are threatened by
any Person, nor are there any valid grounds for any bona fide claims or
infringement liability (i) to the effect that the manufacture, sale, licensing
or use of any of the products of the Company or any Subsidiary infringes on or
misappropriates any Intellectual Property or constitutes unfair competition or
trade practices under the laws of any jurisdiction; (ii) against the use by the
Company or any Subsidiary of any Intellectual Property used in the business of
the Company or any Subsidiary as currently conducted; or (iii) challenging the
ownership by the Company or any Subsidiary, validity or effectiveness of any
Company Intellectual Property. To the Company's knowledge, there is no
unauthorized use, infringement or misappropriation of any Company Intellectual
Property by any third party, including any employee or former employee of the
Company or any Subsidiary.

                  (l)      Each of the Company and the Subsidiaries has taken
reasonable steps to protect the Company's and the Subsidiaries' respective
rights in the Company's and the Subsidiaries' respective confidential
information and trade secrets that it wishes to protect or any trade secrets or
confidential information of third parties provided to the Company or any
Subsidiary, and, without limiting the foregoing, the Company and each of the
Subsidiaries has and enforces a policy requiring each employee and contractor to
execute a proprietary information/nondisclosure agreement substantially in the
form provided to Parent and all current and former employees and contractors of
the Company and the Subsidiaries have executed such an agreement.

                  (m)      None of the Company's nor any Subsidiary's
professional services agreements with customers, agreements with merchants,
agreements with outside consultants for the performance of professional services
on the Company's, any Subsidiary's or customers' behalf, nor any agreement or
license with any end user or reseller of the Company's or any Subsidiary's
products, confers upon any party other than the Company or any Subsidiary any
ownership right with respect to any Intellectual Property developed in
connection with such agreement or license.

                  (n)      Neither the Company nor any Subsidiary has breached
or violated the terms of any license, sublicense, or other agreement relating to
any Commercial Software Rights, and the Company and each of the Subsidiaries has
a valid right to use such Commercial Software Rights under such licenses and
agreements. Neither the Company nor any Subsidiary is nor will be as a result of
the execution and delivery of this Agreement or the performance of the Company's
obligations hereunder, in violation of any license, sublicense, or agreement
relating to Commercial Software Rights. No claims with respect to the Commercial
Software Rights have been asserted or, to the knowledge of the Company, are
threatened by any Person against the Company or any Subsidiary, nor to the
knowledge of the Company are there any valid grounds for any bona fide claims
(i) to the effect that the use of any product as now used by the Company or any
Subsidiary infringes on any Intellectual Property, (ii) against the use by the
Company or any Subsidiary of any Company Intellectual Property or (iii)
challenging the validity or effectiveness of any of the rights of the Company or
any Subsidiary to use Commercial Software Rights. There is no unauthorized use,
infringement, or misappropriation of any of the Commercial Software Rights by
the Company, any Subsidiary or any employee or former employee thereof. To the
knowledge of the Company, no Commercial Software Right is subject to any
outstanding order, judgment, decree, stipulation, or agreement restricting in
any manner the use thereof by the Company or any Subsidiary.

                  (a)      Company Products. Each product manufactured, sold,

         6.1      Preparation of Information Statement.

                  (a)      As soon as practicable after the execution of this
Agreement, the Company shall prepare, with the cooperation of Parent, an
Information Statement (the "Information Statement") for use in connection with
the Company Stockholders Meeting (as defined in Section 6.2) at which the
stockholders of the Company will be asked to approve the terms of this
Agreement, the Merger and the transactions contemplated hereby. Parent and the
Company shall each use its reasonable best efforts to cause the Information
Statement to comply in all material respects with applicable federal and state
securities laws requirements. Each of Parent and the Company agrees to provide
promptly to the other such information concerning its business and financial
statements and affairs as, in the reasonable judgment of the providing party or
its counsel, may be required or appropriate for inclusion in the Information
Statement, or in any amendments or supplements thereto, and to cause its counsel
and auditors to cooperate with the other's counsel and auditors in the
preparation of the Information Statement. The Information Statement shall not,
on the date the Information Statement (or any amendment thereof or supplement
thereto) is first mailed to the Company's stockholders, at the time of the
Company's Stockholders Meeting and at the Effective Time, contain any statement
which, at such time and in light of the circumstances under which it shall be
made, is false or misleading in any material respect or omits to state any
material fact necessary in order to make the statements therein not false or
misleading. The Company will promptly advise Parent and Parent will promptly
advise the Company, in writing, if at any time prior to the Effective Time
either the Company or Parent shall obtain knowledge of any facts that might make
it necessary or appropriate to amend or supplement the Information Statement.
Notwithstanding the foregoing, (i) Parent and Merger Sub make no representation
or warranty with respect to any information regarding the Company and (ii) the
Company makes no representation or warranty with respect to any information
regarding Parent or Merger Sub.

                  (b)      The Information Statement shall contain a statement
that the Board of Directors of the Company has unanimously approved the terms of
this Agreement, the Escrow Agreement, the Merger and the other transactions
contemplated hereby and thereby and the conclusion of the Board of Directors
that the Merger is fair to, and in the best interests of, the Company and its
stockholders. The Information Statement shall contain the unanimous
recommendation of the Board of Directors of the Company that the Company
stockholders approve the terms of this Agreement, the Escrow Agreement, the
Merger and the other transactions contemplated hereby and thereby. Anything to
the contrary contained herein notwithstanding, the Company shall not include in
the Information Statement any information


                                      -41-

transactions contemplated hereby and thereby and (ii) to solicit the approval of
holders of Company Capital Stock of the Merger, this Agreement, the Escrow
Agreement, and the transactions contemplated hereby and thereby. The Company
shall ensure that stockholder approval is solicited in compliance with the
procedural requirements of Delaware Law, the Certificate of Incorporation and

and personnel of the Company and the Subsidiaries as Parent may reasonably
request. The Company agrees to provide Parent and its accountants, legal
counsel, and other representatives copies of internal financial statements
promptly upon request. No information or knowledge obtained in any investigation
pursuant to this Section 6.3 or otherwise shall affect or be deemed to modify
any representation or warranty contained herein or the conditions to the
obligations of the parties to consummate the Merger.

         6.4      Confidentiality. The parties acknowledge that the Company and
Parent have previously executed a Nondisclosure Agreement, dated as of January

Nasdaq, prior to the Effective Time, no disclosure (whether or not in response
to an inquiry) of the subject matter of this Agreement shall be made by any
party hereto (other than disclosures to Company stockholders pursuant to Section
6.2) unless approved by Parent and the Company prior to release, provided that
such approval shall not be unreasonably withheld. In the event that Parent is
required by law or regulatory authority to make any such disclosure, Parent
shall notify the Company prior to making such disclosure and shall use its
reasonable best efforts to give the Company an opportunity to comment on such
disclosure.

         6.6      Consents. The Company shall promptly apply for or otherwise
seek and use its best efforts to obtain all consents and approvals required to
be obtained by it for the consummation of the Merger, including all consents,
waivers, or approvals under any of the

   48

Contracts in order to preserve the benefits thereunder for the Surviving

and approvals are set forth in Schedule 2.6 of the Company Schedules.

         6.7      FIRPTA Compliance. On the Closing Date, the Company shall
deliver to Parent a properly executed statement or statements in a form
reasonably acceptable to Parent for purposes of satisfying Parent's obligations
under Treasury Regulation Section 1.1445-2(c)(3) and 1.897-2(h).

         6.8      Legal Conditions to the Merger. Each of Parent, Merger Sub and
the Company will take all reasonable actions necessary to comply promptly with
all legal requirements which may be imposed on such party with respect to the
Merger and will promptly cooperate with and furnish information to any other
party hereto in connection with any such requirements imposed upon such other
party in connection with the Merger. Each party will take all reasonable actions
to obtain (and will cooperate with the other parties in obtaining) any consent,
authorization, order or approval of, or any registration, declaration, or filing
with, or notice to, or an exemption by, any Governmental Entity, or other third
party, required to be obtained or made by such party or its subsidiaries in
connection with the Merger or the taking of any action contemplated thereby or
by this Agreement.

         6.9      Reasonable Best Efforts; Additional Documents and Further.
Each of the parties to this Agreement shall use its reasonable best efforts to
effectuate the transactions contemplated hereby and to fulfill and cause to be
fulfilled the conditions to Closing under this Agreement. Each party hereto, at
the request of another party hereto, shall execute and deliver such other
instruments and do and perform such other acts and things as may be reasonably
necessary or desirable for effecting completely the consummation of this
Agreement, and the transactions contemplated hereby.

         6.10     Notification of Certain Matters. The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (i) the
occurrence or non-occurrence of any event which has caused or is likely to cause
any representation or warranty of the Company, Parent or Merger Sub,
respectively, contained in this Agreement to be untrue or inaccurate at or prior
to the Effective Time and (ii) any failure of the Company, Parent or Merger Sub,
as the case may be, to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it hereunder; provided, however,
that the delivery of any notice pursuant to this Section 6.10 shall not limit or
otherwise affect any remedies available to the party receiving such notice.

         6.11     Pooling Accounting. Parent and the Company shall each use its
reasonable best efforts to cause the business combination to be effected by the
Merger to be accounted for as a pooling of interests in accordance with GAAP
which shall be acceptable to the SEC. Each of Parent and the Company shall use
its reasonable best efforts to cause its respective employees, directors,
stockholders and Affiliates not to take any action that would adversely affect
the ability of Parent to account for the business combination to be effected by
the Merger as a pooling of interests in accordance with GAAP which shall be
acceptable to the SEC. Neither


                                      -43-
   49

Parent nor the Company shall take any action, either before or after
consummation of the Merger, including the acceleration of vesting of any
options, stock purchase rights, warrants, restricted stock or other rights to
acquire shares of the capital stock of the Company, which reasonably would be
expected to interfere with Parent's ability to account for the Merger as a
pooling of interests in accordance with GAAP which shall be acceptable to the
SEC. At Closing, each of Arthur Andersen, on behalf of Parent, and KPMG, on
behalf of the Company, shall deliver a letter to Parent affirming that firm's
unconditional written concurrence with Parent management's and the Company
management's conclusions, respectively, that no conditions exist that would
preclude Parent from accounting for the Merger as a "pooling of interests" under
Accounting Principles Board Opinion No. 16 and the applicable rules and
regulations of the SEC, if consummated in accordance with this Agreement.

         6.12     Reorganization. It is the intent of the Company, Parent and
the Surviving Corporation that this Merger qualify as a tax-free reorganization
under Section 368(a) of the Code. Neither Parent nor the Company shall take any
action which reasonably would be expected to interfere with the qualification of
the Merger as a tax-free reorganization under Section 368(a) of the Code.
Without limiting the generality of the foregoing, Parent will continue at least
one significant historic business line of the Company, or use at least a
significant portion of the Company's historic business assets in a business, in

with Nasdaq an additional listing application and use its reasonable best
efforts to have the shares of Parent Common Stock issuable in the Merger
accepted by Nasdaq for listing on the Nasdaq National Market as soon as

applicable to the issuance of the Parent Common Stock pursuant hereto. The
Company shall use its reasonable best efforts to assist Parent as may be
necessary to comply with the securities and blue sky laws of all jurisdictions
which are applicable in connection with the issuance of Parent Common Stock

         6.16     Termination of Agreements. The Company shall take such steps
as may be necessary to provide for the termination as of the Closing of the

permit its directors, officers, employees, representatives, investment bankers,
agents, or Affiliates to, directly or indirectly (i) initiate, solicit,
encourage or entertain any inquiries, offers or proposals that constitute, or
could reasonably be expected to


                                      -44-

lead to, any "Acquisition Proposal" (as defined herein) by any Person, or (ii)
participate in any discussions or negotiations with, or disclose any non-public
information concerning the Company or any Subsidiary to, or afford access to the
properties, books, or records of the Company or any Subsidiary, or otherwise
assist or facilitate, or enter into any agreement or understanding with, any
Person (other than Parent and its Affiliates, agents, and representatives) for
the purpose of making, or take any other action to facilitate the making, of an
Acquisition Proposal or inquiry, offer or proposal that could reasonably be
expected to lead to an Acquisition Proposal; or (iii) agree to, approve or
recommend any Acquisition Proposal or change, withdraw or modify its position
with respect to the Merger. For the purposes of this Agreement, "Acquisition

the assets of the Company and its subsidiaries, taken as a whole, immediately
prior to such transaction, or (iv) any public announcement of a proposal, plan
or intention to do any of the foregoing or any agreement to engage in any of the
foregoing. The Company will, and will cause its directors, officers, employees,
representatives, investment bankers, agents and Affiliates to, immediately cease
any and all existing activities, discussions or negotiations with any parties
conducted heretofore with respect to any of the foregoing. The Company will
promptly (i) notify Parent if it receives any proposal or inquiry or request for
information in connection with an Acquisition Proposal or potential Acquisition
Proposal and (ii) notify Parent of the significant terms and conditions of any
such Acquisition Proposal including the identity of the party making an
Acquisition Proposal. In addition, from and after the date of this Agreement
until the earlier to occur of the Effective Time or termination of this
Agreement pursuant to its terms, the Company will not, and will instruct its
directors, officers, employees, representatives, investment bankers, agents, and
Affiliates not to, directly or indirectly, make or authorize any public
statement, recommendation, or solicitation in support of any Acquisition
Proposal made by any Person (other than Parent).

         6.18     Employee Benefits/Other Employee Matters. Nothing contained

dependent, legal representative or collective bargaining agent of such employee
any right or remedy of any nature or kind whatsoever under or by reason of this
Agreement, including without limitation any right to employment or to continued
employment for any specified period, at any specified location or under any
specified job category. It is specifically understood that continued employment
with the Company or employment with Parent is not guaranteed for any employees
of the Company and any


                                      -45-
   51

continuation of employment with the Company after the Closing will be at will
except as specifically provided otherwise in an offer letter or other agreement
of employment. To the extent permitted under Parent's benefit plans and
policies, for purposes of determining prior service credit, employees of the
Company shall receive credit for the duration of their employment with the
Company. The Company shall use its best efforts to cause each employee of the
Company to execute and deliver to Parent Concord's standard confidentiality and
assignment of inventions agreement in the form attached hereto as Exhibit K.

         6.19     Publication of Financial Results. Parent shall publish its
financial results for the quarter ended March 31, 2000 covering at least thirty
days of post-Closing combined operations of Parent and the Company as soon as
reasonably practicable, but in no event later than May 15, 2000.

         6.20     Indemnification of Directors and Officers of the Company.

         (a) Parent shall not, for a period of three years after the Closing
Date, take any action to alter or impair any exculpatory or indemnification
provisions now existing in the Certificate of Incorporation or By-Laws of the
Company for the benefit of any individual who served as a director or officer of
the Company at any time prior to the Effective Time (the "Indemnified Persons"),
except for any changes which do not affect the application of such provisions to
acts or omissions of such individuals prior to the Effective Time.

         (b) From and after the Effective Time, Parent agrees to indemnify and
hold harmless each Indemnified Person against any costs or expenses (including
attorneys' fees), judgments, fines, losses, claims, damages, liabilities or
amounts paid in settlement incurred in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of or pertaining to matters existing or occurring at
or prior to the Effective Time, whether asserted or claimed prior to, at or
after the Effective time, to the fullest extent permitted under Delaware law
(and Parent shall also advance expenses as incurred to the fullest extent
permitted under Delaware law, provided the Indemnified Person to whom expenses
are advanced provides an undertaking to repay such advances if it is ultimately
determined that such Indemnified Person is not entitled to indemnification).
Notwithstanding the foregoing, neither Parent nor the Surviving Corporation
shall be liable for any settlement effected without their written consent, which
shall not be unreasonably withheld or delayed. The Indemnified Parties as a
group may retain only one law firm to represent them with respect to any single
action unless there is, under applicable standards of professional conduct, a
conflict on any significant issue between the positions of any two or more
Indemnified Parties.

               SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ESCROW

         8.1      Survival of Representations and Warranties. All of the
Company's representations and warranties in this Agreement or in any instrument
delivered pursuant to this Agreement shall survive the Merger and continue until
5:00 p.m., Delaware time, on the date


                                      -50-
   56

which is the one year anniversary of the Closing Date (the "Expiration Date").
All of the covenants and agreements of the parties hereto shall survive the
Merger without limitation.

         8.2      Escrow Arrangements.

                  (a)      Escrow Fund. At the Effective Time, the Company's
stockholders will be deemed to have received and deposited with the Escrow Agent
the Escrow Shares (plus any additional shares as may be issued upon any stock
split, stock dividend or recapitalization effected by Parent after the Effective
Time) without any act on the part of any stockholder. As soon as practicable
after the Effective Time, the Escrow Shares, without any act on the part of any
Company stockholder, will be deposited with State Street Bank & Trust Company
(or other institution acceptable to Parent and the Securityholder Agent (as
defined in Section 8.2(g) below)) as Escrow Agent (the "Escrow Agent"), such
deposit to constitute an escrow fund (the "Escrow Fund") to be governed by the
terms set forth in the Escrow Agreement. The number of Escrow Shares deposited
on behalf of each stockholder of the Company shall be in proportion to the
aggregate Parent Common Stock to which such holder would otherwise be entitled
under Sections 1.6(a) and (b) and shall be in the respective share amounts and
percentages listed opposite each Company stockholder's name listed in a schedule
in form and substance reasonably acceptable to Parent to be executed by the
Company and delivered to Parent at Closing (the "Escrow Schedule"). No shares of
Parent Common Stock deposited in the Escrow Fund shall be unvested or subject to
any right of repurchase, risk of forfeiture or other condition in favor of the
Company or the Surviving Corporation. The Escrow Fund shall be available to
reimburse Parent and its Affiliates (including the Surviving Corporation) for
any claims, losses, liabilities, damages, deficiencies, costs and expenses,
including reasonable attorneys' fees and expenses, and expenses of investigation
and defense (hereinafter individually a "Loss" and collectively "Losses")
incurred by Parent, its officers, directors, agents or Affiliates (including the
Surviving Corporation) directly or indirectly as a result of (i) any inaccuracy
in, or breach of, a representation or warranty of the Company contained herein
(or in any certificate, instrument, schedule or document attached to this
Agreement and delivered by the Company in connection with the Merger) or (ii)
any failure by the Company to perform or comply with any covenant contained
herein; provided that claims arising out of an inaccuracy in, or breach of, any
representations and warranties or any covenant of the Company contained in this
Agreement and in any certificate, instrument, schedule or document delivered by
the Company at the Closing in connection with this Agreement or the Merger must
be asserted on or before 5:00 p.m. (Delaware Time) on the Expiration Date.
Losses otherwise subject to reimbursement from the Escrow Fund shall be reduced
by the amount that Parent or its Affiliates recover as proceeds of insurance in
respect of such Losses, net of any cost of collection, deductible, retroactive
premium adjustment, reimbursement obligation or other cost directly related to
the insurance claim in respect of such Losses. Parent agrees that it will
prosecute, and cause its Affiliates to prosecute, claims against its or their
respective insurers diligently and in good faith if, in Parent's reasonable
judgment, it or an Affiliate has a claim against an insurer for such Losses.
Except as otherwise provided herein, Parent may not receive any shares from the
Escrow Fund unless and until Officer's Certificates (as defined in the Escrow
Agreement) identifying Losses, the aggregate amount of which exceed $250,000,
have been delivered to the Escrow Agent as provided in the Escrow Agreement and
such amount is determined pursuant to the Escrow


                                      -51-
   57

Agreement to be payable; in such case, Parent may recover shares from the Escrow
Fund equal in value to all indemnified Losses (including any Losses within the
$250,000 threshold) for which there is no objection or any objection had been
resolved in accordance with the provisions of the Escrow Agreement; and
provided, however, that any Losses incurred by Parent as a result of any
inaccuracy in, or breach of, Sections 2.3, 2.10, 2.14, 2.15, 2.25 and 2.30
hereof shall be immediately reimbursable to Parent in accordance with this
Article VIII (without regard to the $250,000 minimum threshold for Losses and
without counting toward the $250,000 threshold).

                  (b)      Maximum Liability and Remedies. The rights of Parent
to make claims upon the Escrow Fund in accordance with Article VIII and the
Escrow Agreement shall be the sole and exclusive remedy for money damages of
Parent and the Surviving Corporation after the Closing with respect to any
representation, warranty, covenant or agreement made by Company under this
Agreement.

                  (c)      Securityholder Agent of the Stockholders; Power of
Attorney.

                           (i)      In the event that the Merger is approved,
effective upon such vote, and without further act of any stockholder, Timothy
Barrows shall be appointed as agent and attorney-in-fact (the "Securityholder
Agent") for each stockholder of the Company (except such stockholders, if any,
as shall have perfected their dissenters' rights under Delaware Law), for and on
behalf of stockholders of the Company, to act as the Securityholder Agent under
the Escrow Agreement and to give and receive notices and communications, to
authorize delivery to Parent of Escrow Shares from the Escrow Fund in
satisfaction of claims by Parent, to object to such deliveries, to agree to,
negotiate, enter into settlements and compromises of, and demand arbitration and
comply with orders of courts and awards of arbitrators with respect to such
claims, and to take all actions necessary or appropriate in the judgment of
Securityholder Agent for the accomplishment of the foregoing in accordance with
the terms and provisions of the Escrow Agreement. Such agency may be changed by
the stockholders of the Company from time to time upon not less than thirty (30)
days prior written notice to Parent; provided that the Securityholder Agent may
not be removed unless holders of a two-thirds interest of the Escrow Fund agree
to such removal and to the identity of the substituted agent. Any vacancy in the
position of Securityholder Agent may be filled by approval of the holders of a
majority in interest of the Escrow Fund. No bond shall be required of the
Securityholder Agent, and the Securityholder Agent shall not receive
compensation for his or her services. Notices or communications to or from the
Securityholder Agent shall constitute notice to or from each of the stockholders
of the Company.

                           (ii)     The Securityholder Agent shall not be liable
for any act done or omitted hereunder or under the Escrow Agreement as
Securityholder Agent while acting in good faith and in the exercise of
reasonable judgment. The stockholders of the Company on whose behalf the Escrow
Amount was contributed to the Escrow Fund shall jointly indemnify the
Securityholder Agent and hold the Securityholder Agent harmless against any
loss, liability or expense incurred without gross negligence or bad faith on the
part of the Securityholder Agent and arising out of or in connection with the
acceptance or administration of the Securityholder


                                      -52-
   58

Agent's duties hereunder, including the reasonable fees and expenses of any
legal counsel retained by the Securityholder Agent.

                  (d)      Actions of the Securityholder Agent. A decision, act,
consent or instruction of the Securityholder Agent relating to the Escrow
Shares, the Escrow Fund or the Escrow Agreement shall constitute a decision of
all the stockholders for whom a portion of the Escrow Amount otherwise issuable
to them are deposited in the Escrow Fund and shall be final, binding and
conclusive upon each of such stockholders, and the Escrow Agent and Parent may
rely upon any such written decision, consent or instruction of the
Securityholder Agent as being the decision, consent or instruction of each every
such stockholder of the Company. The Escrow Agent and Parent are hereby relieved
from any liability to any Person for any acts done by them in accordance with
such decision, consent or instruction of the Securityholder Agent.

                                   ARTICLE IX

                        TERMINATION, AMENDMENT AND WAIVER

         9.1      Termination. Except as provided in Section 9.2 below, this
Agreement may be terminated and the Merger abandoned at any time prior to the
Closing Date notwithstanding approval thereof by the stockholders of the
Company:

                  (a)      by mutual written consent duly authorized by the
Board of Directors of the Company and Parent;

                  (b)      by either Parent or the Company if: (i) the Closing
Date has not occurred by February 28, 2000 (the "Termination Date") (provided
that the right to terminate this Agreement under this clause 9.1(b)(i) shall not
be available to any party whose failure to fulfill any obligation hereunder has
been the cause of, or resulted in, the failure of the Effective Time to occur on
or before such date and such action or failure constitutes a breach of this
Agreement); (ii) there shall be a final nonappealable order, decree or ruling of
a Governmental Entity having jurisdiction in effect preventing consummation of
the Merger; or (iii) there shall be any statute, rule, regulation or order
enacted, entered, enforced, promulgated, issued or deemed applicable to the
Merger by any Governmental Entity which makes consummation of the Merger
illegal;

                  (c)      by Parent if there shall be any action taken, or any
statute, rule, regulation or order enacted, promulgated or issued or deemed
applicable to the Merger, by any Governmental Entity, which would: (i) prohibit
Parent's or the Company's ownership or operation of any portion of the business
of the Company or (ii) compel Parent or the Company to dispose of or hold
separate, as a result of the Merger, any portion of the business or assets of
the Company or Parent;

                  (d)      by Parent if it is not in material breach of its
obligations under this Agreement and there has been a breach of any
representation, warranty, covenant or agreement contained in this Agreement on
the part of the Company and as a result of such breach the conditions set forth
in Section 7.3(a) or 7.3(b), as the case may be, would not then be satisfied;
provided, however, that if such breach is curable by the Company prior to the
Termination Date


                                      -53-
   59

through the exercise of its reasonable best efforts, then for so long as the
Company continues to exercise such reasonable best efforts Parent may not
terminate this Agreement under this Section 9.1(d) unless such breach is not
cured prior to the Termination Date (but no cure period shall be required for a
breach which by its nature cannot be cured);

                  (e)      by the Company if it is not in material breach of its
obligations under this Agreement and there has been a breach of any
representation, warranty, covenant or agreement contained in this Agreement on
the part of Parent or Merger Sub and as a result of such breach the conditions
set forth in Section 7.2(a) or 7.2(b), as the case may be, would not then be
satisfied; provided, however, that if such breach is curable by Parent or Merger
Sub prior to the Termination Date through the exercise of its reasonable best
efforts, then for so long as Parent or Merger Sub continues to exercise such
reasonable best efforts the Company may not terminate this Agreement under this
Section 9.1(e) unless such breach is not cured prior to the Termination Date
(but no cure period shall be required for a breach which by its nature cannot be
cured).

         Where action is taken to terminate this Agreement pursuant to Section
9.1, it shall be sufficient for such action to be authorized by the Board of
Directors (as applicable) of the party taking such action.

         9.2      Effect of Termination. Except as set forth in Section 10.2,
any termination of this Agreement under Section 9.1 above will be effective
immediately upon the delivery of written notice of the terminating party to the
other parties hereto. In the event of the termination of this Agreement as
provided in Section 9.1, this Agreement shall be of no further force or effect,
except (i) as set forth in this Section 9.2 and Article X (general provisions,
including expenses), each of which shall survive the termination of this
Agreement, and (ii) nothing herein shall relieve any party from liability for
any breach of this Agreement. No termination of this Agreement shall affect the
obligations of the parties contained in the Nondisclosure Agreement, all of
which obligations shall survive termination of this Agreement.

         9.3      Amendment. Except as is otherwise required by applicable law,
prior to the Closing, this Agreement may be amended by the parties hereto at any
time by execution of an instrument in writing signed by Parent and the Company.
Except as is otherwise required by applicable law, after the Closing, this
Agreement may be amended by the parties hereto at any time by execution of an
instrument in writing signed by Parent and by either the Securityholder Agent or
former Company stockholders who receive more than 66 2/3% of the Parent Common
Stock issued pursuant to Section 1.6(a).

         9.4      Extension; Waiver. At any time prior to the Effective Time,
Parent and Merger Sub, on the one hand, and the Company, on the other, may, to
the extent legally allowed, (i) extend the time for the performance of any of
the obligations of the other party hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.

         10.4     Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and

remedies hereunder; and (c) shall not be assigned by operation of law or
otherwise except as otherwise specifically provided, except that Parent and

this Agreement will continue in full force and effect and the application of
such provision to other Persons or circumstances will be interpreted so as

as set forth in Section 8.2), any and all remedies herein expressly conferred
upon a party will be deemed cumulative with and not exclusive of any other

construed in accordance with the laws of the Commonwealth of Massachusetts,
regardless of the laws that might otherwise govern under applicable principles
of conflicts of laws thereof. Each of the parties hereto agrees that process may

Massachusetts for such persons and waives and covenants not to assert or plead
any objection which they might otherwise have to such jurisdiction and such
process.

         10.9     Rules of Construction. The parties hereto agree that they have
been represented by counsel during the negotiation and execution of this
Agreement and, therefore, waive the application of any law, regulation, holding
or rule of construction providing that ambiguities in an agreement or other
document will be construed against the party drafting such agreement or
document.

         10.10    Specific Performance. Notwithstanding Section 8.2, the parties
