                      AGREEMENT AND PLAN OF REORGANIZATION

         This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made and
entered into as of October 17, 2000, by and among Predictive Systems, Inc., a
Delaware corporation ("Acquiror"), Grape Acquisition Corporation, a Delaware
corporation and a wholly-owned subsidiary of Acquiror ("Merger Sub"), Science
Applications International Corporation, a Delaware corporation (the "Principal
Stockholder") and Global Integrity Corporation, a Delaware corporation and
wholly-owned subsidiary of the Principal Stockholder ("Target"). Certain other
capitalized terms used in this Agreement are as defined herein.

                                    RECITALS

         A.     The Boards of Directors of Target, Acquiror and Merger Sub
believe it is in the best interests of their respective companies and the
stockholders of their respective companies that Target and Merger Sub combine
into a single company through the statutory merger of Target with and into
Merger Sub (the "Merger") and, in furtherance thereof, have approved the Merger.

         B.     Pursuant to the Merger, among other things, (i) each outstanding
share of common stock of Target, $0.001 par value ("Target Common Stock"), shall
be converted into shares of common stock of Acquiror, $0.001 par value
("Acquiror Common Stock"), at the rate set forth herein and (ii) each holder of
Target Common Stock shall receive a cash payment as set forth herein.

         C.     Target, Acquiror, Merger Sub and the Principal Stockholder
desire to make certain representations and warranties and other agreements in
connection with the Merger.

         D.     The parties intend, by executing this Agreement, to adopt a plan
of reorganization within the meaning of Section 368 of the Internal Revenue Code
of 1986, as amended (the "Code"), and to cause the Merger to qualify as a
reorganization under the provisions of Sections 368(a) of the Code.

         NOW, THEREFORE, in consideration of the covenants and representations
set forth herein, and for other good and valuable consideration, the parties
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, the
Certificate of Merger attached hereto as Exhibit A (the "Certificate of Merger")
and the applicable provisions of the Delaware General Corporation Law ("DGCL"),
Target shall be merged with and into Merger Sub, the separate corporate
existence of Target shall cease and Merger Sub shall continue as the surviving
corporation. Merger Sub as the surviving corporation after the Merger is
hereinafter sometimes referred to as the "Surviving Corporation."


                                       1
<PAGE>

         1.2    Closing; Effective Time. The closing of the transactions
contemplated hereby (the "Closing") shall take place as soon as practicable
after the satisfaction or waiver of each of the conditions set forth in Article
VI hereof or at such other time as the parties hereto agree (the date on which
the Closing shall occur, the "Closing Date"). The Closing shall take place at
the offices of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, 733
Third Avenue, New York, New York, 10017, or at such other location as the
parties hereto agree. On the Closing Date, the parties hereto shall cause the
Merger to be consummated by filing the Certificate of Merger with the Secretary
of State of the State of Delaware, in accordance with the relevant provisions of
the DGCL (the time and date of such filing being the "Effective Time" and the
"Effective Date," respectively).

         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 DGCL. Without limiting the generality of the foregoing,
and subject thereto, at the Effective Time, all the property, rights,
privileges, powers and franchises of Target shall vest in the Surviving
Corporation, and all debts, liabilities and duties of Target shall become the
debts, liabilities and duties of the Surviving Corporation.

         1.4    Certificate of Incorporation; Bylaws.

                (a) At the Effective Time, the Certificate of Incorporation of
Merger Sub, as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by the DGCL and such Certificate of Incorporation; provided,
however, that Article I of the Certificate of Incorporation shall be amended to
read as follows: "The name of the corporation is Global Integrity Corporation."

                (b) The Bylaws of Merger Sub, as in effect immediately prior to
the Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter amended.

         1.5    Directors and Officers. At the Effective Time, the directors of
Merger Sub immediately prior to the Effective Time shall be the directors of the
Surviving Corporation, to hold office until such time as such directors resign,
are removed or their respective successors are duly elected or appointed and
qualified. The officers of Merger Sub immediately prior to the Effective Time
shall be the officers of the Surviving Corporation, to hold office until such
time as such officers resign, are removed or their respective successors are
duly elected or appointed and qualified.

         1.6    Effect on Capital Stock. By virtue of the Merger and without any
action on the part of Acquiror, Merger Sub, Target or the holders of any of
Target's securities:

                (a) Conversion of Target Common Stock.

                    (i) At the Effective Time, the total amount of consideration
(consisting of Acquiror Common Stock valued as set forth below and cash) to be
paid by Acquiror (including Acquiror Common Stock to be reserved for issuance
upon exercise of unexpired and unexercised options outstanding to purchase
Target Common Stock assumed by Acquiror pursuant to 1.6(c), whether vested or
unvested ("Target Options")) in exchange for all outstanding shares of Target


                                       2
<PAGE>

Common Stock and the assumption of Target Options shall be (A) five million
seven hundred ninety one thousand three hundred twenty three (5,791,323),
multiplied by the weighted average closing market price of the Acquiror Common
Stock as quoted on the Nasdaq National Market for the five trading days
immediately prior to the Effective Date (the "Closing Price"), plus (B) twenty
eight million four hundred sixty thousand two hundred seventy dollars
($28,460,270) (such sum, the "Initial Total Consideration"). Other than for
additional cash payments to holders of Target Common Stock pursuant to Section
1.6(a)(vi) and adjustments to the Option Exchange Ratio (as defined in Section
5.15) of Target Options pursuant to 5.15(a) resulting from the application of
the calculation set forth on Annex A hereto, and pursuant to the provisions of
Section 1.6(a)(vii), in no event shall the number of shares of Acquiror Common
Stock to be issued in respect of the outstanding shares of Target Common Stock
and Target Options, at any time, exceed 5,791,323 in the aggregate nor shall the
cash to be paid to the stockholders of Target Common Stock pursuant to this
Section 1.6, at any time, exceed $28,460,270.

                    (ii) Subject to Section 1.6(a)(iii) below, the amount of
Initial Total Consideration allocable to the outstanding Target Common Stock
(the "Initial Target Stockholder Consideration") shall equal the product of the
Initial Total Consideration multiplied by a fraction, the numerator of which is
the number of shares of Target Common Stock outstanding, and the denominator of
which is the number of shares of Target Common Stock outstanding plus the number
of shares of Target Common Stock issuable upon exercise of outstanding Target
Options. The amount of Initial Total Consideration allocable to the outstanding
Target Options (the "Initial Target Optionholder Consideration") shall equal the
product of the Initial Total Consideration multiplied by a fraction, the
numerator of which is the number of shares of Target Common Stock issuable upon
exercise of outstanding Target Options, and the denominator of which is the
number of shares of Target Common Stock outstanding plus the number of shares of
Target Common Stock issuable upon exercise of outstanding Target Options. All
calculations under this subparagraph (ii) shall be made based on the number of
Target Options or shares of Target Common Stock outstanding immediately prior to
the Effective Time.

                    (iii) The Initial Target Stockholder Consideration shall be
comprised as follows: (A) $28,460,270 (the "Cash Consideration"), and (B) a
number of shares of Acquiror Common Stock (the "Stock Consideration") obtained
by dividing (x) the amount by which the Initial Target Stockholder Consideration
exceeds the Cash Consideration, by (y) the Closing Price.

                    (iv) At the Effective Time, each share of Target Common
Stock issued and outstanding immediately prior to the Effective Time (other than
shares of Target Common Stock to be cancelled pursuant to Section 1.6(b) and
Dissenting Shares, as defined in Section 1.6(h)) will be canceled and
extinguished and be converted automatically into the right to receive (A) a
number of shares of Acquiror Common Stock equal to the Stock Consideration
divided by the number of shares of Target Common Stock then outstanding (the
"Exchange Ratio"), and (B) an amount of cash equal to the Cash Consideration
divided by the number of shares of Target Common Stock then outstanding.
Notwithstanding the foregoing, the amount of Cash Consideration otherwise
payable to the Principal Stockholder pursuant to this Section 1.6 shall be
reduced by the amount of debt (the "Debt") greater than three million dollars


                                       3
<PAGE>

($3,000,000) to be repaid to the Principal Stockholder by or on behalf of Target
pursuant to Section 5.25.

                    (v) No adjustment shall be made in the number of shares of
Acquiror Common Stock issued in the Merger as a result of (A) any increase or
decrease in the market price of Acquiror Common Stock prior to the Effective
Time or (B) any cash proceeds received by Target from the date hereof to the
Closing Date pursuant to the exercise of currently outstanding Target Options.

                    (vi) In addition to the Initial Target Stockholder
Consideration, at the time specified and upon the achievement of the milestones
set forth on Annex A hereto, the former holders of shares of Target Common Stock
shall receive the "Additional Target Stockholder Consideration," as defined on
and calculated pursuant to Annex A hereto. At such specified time, each such
holder shall receive an amount of Additional Target Stockholder Consideration
equal to (A) the aggregate Additional Target Stockholder Consideration, divided
by the number of shares of Target Common Stock held by such holders on the
Effective Date, multiplied by (B) the number of shares of Target Common Stock
such holder held on the Effective Date.

                    (vii) If either (i) the tax opinion referred to in Section
6.1 of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP
("Gunderson") cannot be rendered (as reasonably determined by Gunderson Dettmer
and concurred in by Heller Ehrman White & McAuliffe LLP ("Heller") or (ii) the
tax opinion referred to in Section 6.1 of Heller cannot be rendered (as
reasonably determined by Heller and concurred in by Gunderson), in either case a
result of the Merger potentially failing to satisfy the requirements of Section
368(a) of the Code, then Acquiror shall reduce to the minimum extent necessary
to enable the relevant tax opinion or opinions, as the case may be, to be
rendered, the Cash Consideration and correspondingly increase the Stock
Consideration by an amount equal to the decrease in the Cash Consideration
divided by the Closing Price.

                (b) Cancellation of Target Capital Stock Owned by Acquiror or
Target. Immediately prior to the Effective Time, all shares of capital stock of
Target ("Target Capital Stock") that are owned by Target as treasury stock, and
each share of Target Capital Stock owned by Acquiror or any direct or indirect
wholly owned subsidiary of Acquiror or of Target immediately prior to the
Effective Time shall be canceled and extinguished without any conversion
thereof.

                (c) Target Stock Option Plans. At the Effective Time, the Target
1998 Stock Incentive Plan, as amended and restated on April 27, 2000 (the
"Target Stock Option Plan") and all options to purchase Target Common Stock then
outstanding under the Target Stock Option Plan shall be assumed by Acquiror in
accordance with Section 5.15.

                (d) [Reserved.]

                (e) Capital Stock of Merger Sub. At the Effective Time, each
share of Common Stock, $0.001 par value, of Merger Sub ("Merger Sub Common
Stock"), issued and outstanding immediately prior to the Effective Time, shall
be converted into and exchanged for one validly issued, fully paid and


                                       4
<PAGE>

nonassessable share of Common Stock, $0.001 par value, of the Surviving
Corporation. Each stock certificate of Merger Sub evidencing ownership of any
such shares shall thereupon evidence ownership of such shares of capital stock
of the Surviving Corporation.

                (f) Adjustments to Exchange Ratio. The Exchange Ratio shall be
adjusted to reflect fully the effect of any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Acquiror Common Stock or Target Common Stock), reorganization, recapitalization
or other like change with respect to Acquiror Common Stock occurring after the
date hereof and prior to the Effective Time.

                (g) Fractional Shares. No fraction of a share of Acquiror Common
Stock will be issued, but in lieu thereof each holder of shares of Target Common
Stock who would otherwise be entitled to a fraction of a share of Acquiror
Common Stock (after aggregating all fractional shares of Acquiror Common Stock
to be received by such holder) shall receive from Acquiror an amount of cash
(rounded to the nearest whole cent) equal to the product of (i) such fraction,
multiplied by (ii) the closing market price of the Acquiror Common Stock on the
Effective Date.

                (h) Dissenters' Rights. Shares of Target Common Stock held by
persons who have not voted such shares for approval of the Merger and with
respect to which such persons shall be entitled to exercise dissenters' rights
in accordance with Section 262 of the DGCL ("Dissenting Shares") shall not be
converted into Acquiror Common Stock and cash but shall instead be converted
into the right to receive such consideration as may be determined to be due with
respect to such Dissenting Shares pursuant to the DGCL. Target agrees that,
except with the prior written consent of Acquiror, or as required under the
DGCL, it will not voluntarily make any payment with respect to, or settle or
offer to settle, any such purchase demand. Each holder of Dissenting Shares
("Dissenting Stockholder") who, pursuant to the provisions of the DGCL, becomes
entitled to payment of the fair value for shares of Target Common Stock shall
receive payment therefor (but only after the value therefor shall have been
agreed upon or finally determined pursuant to such provisions). If, after the
Effective Time, any Dissenting Shares shall lose their status as Dissenting
Shares, Acquiror shall issue and deliver, upon surrender by such stockholder of
certificate or certificates representing shares of Target Common Stock, the cash
and the number of shares of Acquiror Common Stock to which such stockholder
would otherwise be entitled under this Section 1.6 and the Certificate of
Merger, less the cash and the number of shares allocable to such stockholder
that have been or will be deposited in the Escrow Fund (as defined below) in
respect of such shares of Acquiror Common Stock pursuant to Section 1.7(c) and
Article VIII hereof.

         1.7    Surrender of Certificates.

                (a) Exchange Agent. American Stock Transfer & Trust Company
shall act as exchange agent (the "Exchange Agent") in the Merger.

                (b) Acquiror to Provide Common Stock and Cash. Promptly after
the Effective Time, Acquiror shall make available to the Exchange Agent for
exchange in accordance with this Article I, through such reasonable procedures
as Acquiror may adopt, the Stock Consideration issuable pursuant to Section


                                       5
<PAGE>

1.6(a) in exchange for shares of Target Common Stock outstanding immediately
prior to the Effective Time less (i) the Cash Consideration and the Stock
Consideration to be deposited into an escrow fund (the "Escrow Fund") pursuant
to the requirements of Article VIII hereof and (ii) cash in an amount sufficient
to permit payment of cash in lieu of fractional shares pursuant to Section
1.6(g).

                (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 Target Common Stock, whose
shares were converted into the right to receive shares of Acquiror Common Stock
(and cash in lieu of fractional shares) pursuant to Section 1.6, (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon receipt of the
Certificates by the Exchange Agent, and shall be in such form and have such
other provisions as Acquiror may reasonably specify) and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for cash and
certificates representing shares of Acquiror Common Stock (and cash in lieu of
fractional shares). Upon surrender of a Certificate for cancellation to the
Exchange Agent or to such other agent or agents as may be appointed by Acquiror,
together with such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, the holder of such Certificate shall
be entitled to receive in exchange therefor cash and a certificate representing
the number of whole shares of Acquiror Common Stock and payment in lieu of
fractional shares which such holder has the right to receive pursuant to Section
1.6 (less the number of shares of Acquiror Common Stock to be deposited in the
Escrow Fund on such holder's behalf pursuant to Article VIII hereof), and the
Certificate so surrendered shall forthwith be canceled. Until so surrendered,
each outstanding Certificate that, prior to the Effective Time, represented
shares of Target Common Stock 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 Acquiror Common Stock into which such
shares of Target Common Stock shall have been so converted and the right to
receive an amount in cash in accordance with Section 1.6. As soon as practicable
after the Effective Time, and subject to and in accordance with the provisions
of Section 8.3 hereof, Acquiror shall cause to be delivered to the Escrow Agent
(as defined in Section 8.3 hereof) a certificate or certificates (the "Escrow
Certificates") representing a number of shares of Acquiror Common Stock equal to
the Escrow Consideration divided by the Closing Price (which shall be registered
in the name of the Escrow Agent as nominee for such stockholders of Target). The
"Escrow Consideration" shall be 5% multiplied by the Initial Target Stockholder
Consideration otherwise deliverable to the Principal Stockholder pursuant to
Section 1.6 (calculated prior to reduction for the Debt in excess of $3,000,000
to be repaid pursuant to Section 1.6(a)(iv) and Section 5.25). The shares
deposited in the Escrow Fund shall be beneficially owned by the Principal
Stockholder and shall be held in escrow and shall be available to compensate
Acquiror for certain damages as provided in Article VIII. To the extent not used
for such purposes, such shares shall be released, all as provided in Article
VIII hereof.

                (d) Distributions with Respect to Unexchanged Shares. No
dividends or other distributions with respect to Acquiror Common Stock with a
record date after the Effective Time shall be paid to the holder of any
unsurrendered Certificate with respect to the shares of Acquiror Common Stock
represented thereby until the holder of record of such Certificate surrenders


                                       6
<PAGE>

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 Acquiror Common Stock issued in exchange therefor,
without interest, at the time of such surrender, the amount of any such
dividends or other distributions with a record date after the Effective Time
which would have been previously payable (but for the provisions of this Section
1.7(d)) with respect to such shares of Acquiror Common Stock.

                (e) Transfers of Ownership. If any certificate for shares of
Acquiror Common Stock is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it shall be a
condition of the issuance thereof that such issuance be in accordance with
applicable law and that the Certificate so surrendered is properly endorsed and
otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Acquiror or any agent designated by it any transfer
or other taxes required by reason of the issuance of a certificate for shares of
Acquiror Common Stock in any name other than that of the registered holder of
the Certificate surrendered, or established to the satisfaction of Acquiror 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 1.7, none of the Exchange Agent, the Surviving Corporation or any
party hereto shall be liable to any person for any amount properly paid to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

                (g) Dissenting Shares. The provisions of this Section 1.7 shall
also apply to Dissenting Shares that lose their status as such, except that the
obligations of Acquiror under this Section 1.7 shall commence on the date of
loss of such status and the holder of such shares shall be entitled to receive
in exchange for such shares the number of shares of Acquiror Common Stock to
which such holder is entitled pursuant to Section 1.6 hereof.

                (h) Withholding Rights. Each of the Surviving Corporation and
Acquiror shall be entitled to deduct and withhold from the consideration
otherwise payable pursuant to this Agreement to any holder of shares of Target
Stock such amounts as it is required to deduct and withhold with respect to the
making of such payment under the Code, or any provision of state, local or
foreign tax law. To the extent that amounts are so withheld by the Surviving
Corporation or Acquiror, as the case may be, such withheld amounts shall be
treated for all purposes of this Agreement as having been paid to the holder of
the shares of Target Stock in respect of which such deduction and withholding
was made by the Surviving Corporation or Acquiror, as the case may be.

         1.8    No Further Ownership Rights in Target Common Stock. All shares
of Acquiror Common Stock issued upon the surrender for exchange of shares of
Target Common Stock in accordance with the terms hereof (including any cash paid
in lieu of fractional shares) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Target Common Stock, and
there shall be no further registration of transfers on the records of the
Surviving Corporation of shares of Target Common 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.


                                       7
<PAGE>

         1.9    Lost, Stolen or Destroyed Certificates. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of
Acquiror Common Stock (and cash in lieu of fractional shares) as may be required
pursuant to Section 1.6; provided, however, that Acquiror 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
reasonably direct as indemnity against any claim that may be made against
Acquiror, the Surviving Corporation or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

         1.10   Tax Consequences. It is intended by the parties hereto that the
Merger shall constitute a reorganization within the meaning of Section 368 of
the Code. No party shall take any action which would, to such party's knowledge,
cause the Merger to fail to qualify as a reorganization within the meaning of
Section 368 of the Code.

         1.11   Taking of Necessary Action; Further Action. If, at any time
after the Effective Time, any 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 Target, the officers and directors of Target and Merger
Sub are fully authorized in the name of their respective corporations or
otherwise to take, and shall take, all such lawful and necessary action, so long
as such action is not inconsistent with this Agreement.

                                   ARTICLE II

             REPRESENTATIONS AND WARRANTIES OF TARGET AND PRINCIPAL
                                  STOCKHOLDER

         Target and the Principal Stockholder, jointly and severally, represent
and warrant to Acquiror and Merger Sub that the statements contained in this
Article II are true and correct, except as set forth in the disclosure letter
delivered by Target to Acquiror prior to the execution and delivery of this
Agreement, as amended in accordance with Section 5.8(b), subject to the last
sentence of 5.8(b) (the "Target Disclosure Letter"). The Target Disclosure
Letter shall be arranged in paragraphs corresponding to the numbered and
lettered paragraphs contained in this Article II, and the disclosure in any
paragraph shall qualify only the corresponding paragraph in this Article II. Any
reference in this Article II to an agreement being "enforceable" shall be deemed
to be qualified to the extent such enforceability is subject to (i) laws of
general application relating to bankruptcy, insolvency, moratorium and the
relief of debtors, and (ii) the availability of specific performance, injunctive
relief and other equitable remedies.

         2.1    Organization, Standing and Power. Target is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization. Target has the corporate power to own its
properties and to carry on its business as now being conducted and as proposed
to be conducted and is duly qualified to do business and is in good standing in
each jurisdiction in which the failure to be so qualified and in good standing
would have a Material Adverse Effect (as defined in Section 9.2) on Target.
Target has delivered to Acquiror a true and correct copy of the Certificate of
Incorporation and Bylaws or other charter documents, as applicable, of Target,


                                       8
<PAGE>

each as amended to date. Target is not in violation of any of the provisions of
its Articles of Incorporation or Bylaws or equivalent organizational documents.
Target does not own any subsidiaries and does not directly or indirectly own any
equity or similar interest in, or any interest convertible or exchangeable or
exercisable for, any equity or similar interest in, any corporation,
partnership, joint venture or other business association or entity.

         2.2    Capital Structure. The authorized capital stock of Target
consists of 32,000,000 shares of Target Common Stock and 5,000,000 shares of
preferred stock, $0.001 par value per share (the "Target Preferred Stock"), of
which there were issued and outstanding as of the date of this Agreement,
16,000,000 shares of Target Common Stock and no shares of Target Preferred
Stock. There are no other outstanding shares of capital stock or voting
securities and no outstanding commitments to issue any shares of capital stock
or voting securities after the date of this Agreement other than pursuant to the
exercise of options outstanding as of the date of this Agreement under the
Target Stock Option Plan. All outstanding shares of Target Common Stock are duly
authorized, validly issued, fully paid and non-assessable and are free of any
liens or encumbrances other than any liens or encumbrances created by or imposed
upon the holders thereof, and are not subject to preemptive rights, rights of
first refusal, rights of first offer or similar rights created by statute, the
Certificate of Incorporation or Bylaws of Target or any agreement to which
Target is a party or by which it is bound. As of the date of this Agreement,
Target has reserved 2,400,000 shares of Target Common Stock for issuance to
employees, directors and consultants pursuant to the Target Stock Option Plan,
of which no shares have been issued pursuant to option exercises or direct stock
purchases, 2,358,200 shares are subject to outstanding, unexercised options.
Except for (i) the rights created pursuant to this Agreement, and (ii) rights
created pursuant to the Target Stock Option Plan, there are no other options,
warrants, calls, rights, commitments or agreements of any character to which
Target is a party or by which it is bound obligating Target to issue, deliver,
sell, repurchase or redeem, or cause to be issued, delivered, sold, repurchased
or redeemed, any shares of Target Capital Stock or obligating Target to grant,
extend, accelerate the vesting of, change the price of, or otherwise amend or
enter into any such option, warrant, call, right, commitment or agreement. The
Target Disclosure Letter also sets forth a true, correct and complete list of
all outstanding Target Options (which, for each outstanding option, sets forth,
as of the date of this Agreement, the name of the holder of such option, the
number of shares subject to such options, the amount of such options that are
vested and the vesting schedule for any unvested options, the type of stock
subject to such option, the exercise price of such option, the repricing of any
such option and, if the exercisability of such option will be or is required to
be accelerated in any way by the transactions contemplated by this Agreement or
for any other reason, an indication of the extent of such acceleration and the
reason therefor) (the "Option Schedule"). There are no contracts, commitments or
agreements relating to the voting, purchase or sale of Target Capital Stock (i)
between or among Target and any of its stockholders and (ii) to the best of
Target's knowledge, among any of Target's stockholders or between any of
Target's stockholders and any third party, except for the stockholders
delivering Voting Agreements. The terms of the Target Stock Option Plan permit
the assumption of such Target Stock Option Plan by Acquiror or the substitution
of options to purchase Acquiror Common Stock as provided in this Agreement,
without the consent or approval of the holders of the outstanding options, the
Target stockholders, or otherwise and without any acceleration of the exercise
schedule or vesting provisions in effect for such options. True and complete


                                       9
<PAGE>

copies of all agreements and instruments relating to or issued under the Target
Stock Option Plan have been made available to Acquiror, and such agreements and
instruments have not been amended, modified or supplemented, and there are no
agreements to amend, modify or supplement such agreements or instruments from
the form made available to Acquiror. All outstanding Target Capital Stock,
Target Options, Target Warrants and other Target securities, if any, were issued
in compliance with all applicable federal and state securities laws, except
where the failure to so comply would not have a Material Adverse Effect on
Target.

         2.3    Authority.

                (a) Target has all requisite corporate power, and authority to
enter into this Agreement, the Escrow Agreement, in substantially the form as

Stockholder and The Chase Manhattan Bank, as Escrow Agent (the "Escrow
Agreement"), and the Amended and Restated the Registration Rights Agreement, in
substantially the form as Exhibit H hereto, to be entered into among Acquiror,
the Principal Stockholder, and the stockholders of Acquiror named therein (the
"Registration Rights Agreement, and with this Agreement and the Escrow
Agreement, collectively, the "Transaction Documents") and to consummate the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the other Transaction Documents and the consummation of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action on the part of Target, subject only to the approval
of the Merger by Target's stockholders as contemplated by Section 6.1(a). This
Agreement and other Transaction Documents have been duly executed and delivered
by Target and constitute the valid and binding obligations of Target enforceable
against Target in accordance with their terms.

                (b) The execution and delivery of this Agreement and the other
Transaction Documents by Target do not, and the consummation of the transactions
contemplated hereby and thereby 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 (i) any provision of the Certificate
of Incorporation or Bylaws of Target, as amended, or (ii) any contract or any
permit, concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to Target or any of its properties or
assets, except for such conflicts, violations, defaults, rights or losses which
would not have a Material Adverse Effect on Target. Without limiting the
generality of the forgoing, the Target Board of Directors has unanimously (i)
approved the Merger, (ii) resolved to recommend approval and adoption of this
Agreement and the Merger by the Target stockholders, and (iii) has not withdrawn
or modified such approval or resolution to recommend.

                (c) No consent, approval, order or authorization of, or
registration, declaration or filing with, any court, administrative agency or
commission or other governmental authority or instrumentality ("Governmental
Entity") is required by or with respect to Target in connection with the
execution and delivery of this Agreement and the other Transaction Documents or
the consummation of the transactions contemplated hereby or thereby, except for
(i) the filing of the Certificate of Merger, together with the required
officers' certificates, as provided in Section 1.2; (ii) such consents,
approvals, orders, authorizations, registrations, declarations and filings as


                                       10
<PAGE>

may be required under applicable state securities laws and the securities laws
of any foreign country; (iii) such filings as may be required under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended ("HSR"); and
(iv) such other consents, authorizations, filings, approvals and registrations
which have been made or, if not obtained or made, would not have a Material
Adverse Effect on Target and would not prevent, or delay beyond January 15, 2001
any of the transactions contemplated by this Agreement.

         2.4    Financial Statements. Target has delivered, or if not delivered
prior to date hereof, will deliver prior to the Closing, to Acquiror its audited
financial statements (balance sheet, statement of operations, statement of
stockholders' equity and statement of cash flows) for the fiscal year ended
January 31, 1999 and 2000, and its unaudited financial statements (balance
sheet, statement of operations, statement of stockholders' equity and statement
of cash flows) on a consolidated basis as at, and for the eight-month period
ended September 29, 2000 (collectively, the "Financial Statements"). The
Financial Statements have been (or will be) prepared in accordance with
generally accepted accounting principles ("GAAP") (except that the unaudited
financial statements do not have notes thereto) applied on a consistent basis
throughout the periods indicated and with each other. The Financial Statements
fairly present (or will fairly present), in all material respects, the financial
condition and operating results of Target as of the dates, and for the periods,
indicated therein, subject; in the case of the unaudited financial statements,
to normal year-end audit adjustments which are not material in the aggregate.
Target maintains a standard system of accounting established and administered in
accordance with GAAP.

         2.5    Absence of Certain Changes. Since September 29, 2000, Target has
conducted its business in the ordinary course consistent with past practice and
there has not occurred: (i) any material adverse change to the business,
financial condition or results of operation or the properties, assets and
liabilities of Target, but excluding changes arising from or relating to:

                (A)     conditions generally affecting the information security,
                        information technology, technology, e-commerce, banking
                        or financial services industries; or

                (B)     conditions generally affecting the United States
                        economy;

(ii) any acquisition, sale or transfer of any material asset of Target; (iii)
any change in accounting methods or practices (including any change in
depreciation or amortization policies or rates) by Target or any revaluation by
Target of any of its assets; (iv) any declaration, setting aside, or payment of
a dividend or other distribution with respect to the shares of Target, or any
direct or indirect redemption, purchase or other acquisition by Target of any of
its shares of capital stock; (v) any contract entered into by Target, other than
as provided to Acquiror, or any amendment or termination of, or default under,
any contract to which Target is a party or by which it is bound that has
resulted in, or is reasonably likely to result in, a Material Adverse Effect on
Target; (vi) any amendment or change to the Certificate of Incorporation or
Bylaws of Target; (vii) any increase in or modification of the compensation or
benefits payable or to become payable by Target to any of its directors,
employees or consultants whose annual compensation is $100,000 or more; (viii)


                                       11
<PAGE>

capital expenditures or capital commitments by Target exceeding $100,000
individually or $500,000 in the aggregate; (ix) any transaction or agreement
with the Principal Stockholder other than the loaning of funds by the Principal
Stockholder to Target in the ordinary course of business consistent with past
practices and repayment of such funds by Target to the Principal Stockholder;
and (x) any agreement by Target to do any of the things described in the
preceding clauses (i) through (ix).

        2.6     Absence of Undisclosed Liabilities. Target has no material
obligations or liabilities of any nature (matured or unmatured, fixed or
contingent) other than (i) those set forth or adequately provided for in the
Balance Sheet for the period ended September 29, 2000 (the "Target Balance
Sheet"), (ii) those incurred in the ordinary course of business after September
29, 2000, (iii) those not required to be set forth in the Target Balance Sheet
under GAAP and (iv) those incurred in connection with the execution of this
Agreement.

        2.7     Accounts Receivable. The accounts receivable to be listed on the
Target Balance Sheet arose in the ordinary course of business in connection with
bona fide transactions. To Target's knowledge, no material amount of the
accounts receivable are subject to any material claim of offset or recoupment,
or counterclaim except for accounts receivable expressly reserved against in the
Target Balance Sheet. Other than with respect to contracts recorded on a
percentage completion basis, no material amount of accounts receivable are
contingent upon the performance by Target of any obligation.

        2.8     Litigation. There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of Target and the
Principal Stockholder, threatened against Target or the Principal Stockholder,
or any of their respective properties or officers or directors (in their
capacities as such) that, individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect on Target. There is no judgment,
decree or order against Target or the Principal Stockholder, or, to the
knowledge of Target or the Principal Stockholder, any of their respective
directors or officers (in their capacities as such), that could prevent, enjoin,
or materially delay any of the transactions contemplated by this Agreement, or
that could reasonably be expected to have a Material Adverse Effect on Target.
Target does not have any plans to initiate any litigation, arbitration or other
proceeding against any third party, other than for the routine collection of
bills. The Principal Stockholder does not have any plans to initiate any
litigation, arbitration or other proceeding against any third party relating to
Target.

        2.9     Restrictions on Business Activities. There is no agreement,
judgment, injunction, order or decree binding upon Target or the Principal
Stockholder, that has or could reasonably be expected to have the effect of
prohibiting or impairing any current business practice of Target, any
acquisition of property by Target or the conduct of business by Target as
currently conducted in a manner that would result in a Material Adverse Effect
on Target.

        2.10    Governmental Authorization. Target has obtained each federal,
state, county, local or foreign governmental consent, license, permit, grant, or
other authorization of a Governmental Entity (i) pursuant to which Target
currently operates or holds any interest in any of its properties or (ii) that
is required for the operation of Target's business as currently conducted or the
holding of any such interest ((i) and (ii) herein collectively called "Target


                                       12
<PAGE>

Authorizations"), and all of such Target Authorizations are in full force and
effect, except where the failure to obtain or have any such Target
Authorizations would not have a Material Adverse Effect on Target.

        2.11    Title to Property. Target has good and valid title to all
properties, and assets, real and personal it owns or uses for the conduct of its
business as presently conducted including without limitation those that are or
will be reflected in the Target Balance Sheet or acquired after September 29,
2000 (except properties, and assets sold or otherwise disposed of in the
ordinary course of business since September 29, 2000), or with respect to leased
properties and assets, valid leasehold interests therein, in each case free and
clear of all mortgages, liens, pledges, charges or encumbrances of any kind or
character, except (i) the lien of current taxes not yet due and payable, (ii)
such imperfections of title, liens and easements as do not and will not
materially detract from or interfere with the use of the properties subject
thereto or affected thereby, or otherwise materially impair business operations
involving such properties and (iii) liens securing debt to be reflected on the
Target Balance Sheet. All material tangible assets used as of September 19, 2000
in the business and operations of Target are set forth on Schedule 2.11. Other
than as set forth on Schedule 2.11, Target does not utilize any other properties
or assets, whether or not owned by the Principal Stockholder or any Affiliate
thereof, in the conduct of its business. Schedule 2.11 identifies each parcel of
real property owned or leased by Target.

        2.12    Intellectual Property.

                (a) Except as identified in Parts I and II to Schedule
2.12(a)(i), Target is the sole and exclusive owner of, or has the valid and
enforceable right to exploit (to the extent reasonably necessary for Target to
conduct its business as presently conducted or as currently proposed to be
conducted), all Target Intellectual Property (defined below). Except as
identified in Schedule 2.12(a)(ii), assuming Target continues to conduct its
business as it presently is being conducted or as it is proposed to be
conducted, the Target Intellectual Property is free of all contingent and
noncontingent liens, restrictions, interests, rights of reversion or termination
and all other encumbrances of any nature that could reasonably be expected to
have a material adverse effect on the business, operations, financial condition
or results of operation of Target. The conduct of Target's business as currently
conducted by Target or as currently proposed to be conducted, to Target's best
knowledge, will not infringe, misappropriate or violate any Intellectual
Property (defined below) of others. Except as set forth in Schedule
2.12(a)(iii): (w) Principal Stockholder has transferred or assigned, or will
transfer or assign, to Target all right, title and interest in and to Target
Intellectual Property that was owned by the Principal Stockholder and is
exclusively used in connection with the business of Target as presently
conducted or as currently proposed to be conducted; (x) Principal Stockholder
has transferred or assigned, or will transfer or assign, to Target all right,
title and interest in and to Principal Stockholder's licenses or agreements, if
any, with respect to Target Intellectual Property which is exclusively used by
Target in connection with the business of Target as presently conducted or as
currently proposed to be conducted, except any non-assignable off-the-shelf
software available to Target on commercially reasonable terms; and (y) Principal
Stockholder has licensed to Target the right to fully exploit all Target
Intellectual Property which is owned by Principal Stockholder and used
nonexclusively by Target in connection with the business of Target as presently
conducted or as currently proposed to be conducted; and (z) Principal

lawfully imposed by governmental authority under federal, state or local law
pertaining to the protection of the environment, protection of public health,

        2.14    Taxes.

                (a) All Tax returns, statements, reports, declarations and other
forms and documents (including without limitation estimated Tax returns and
reports and material information returns and reports) required to be filed with
any Tax authority with respect to any Taxable period ending on or before the
Closing, by or on behalf of Target (collectively, "Tax Returns" and individually
a "Tax Return"), have been or will be completed and filed when due (including
any extensions of such due date) and all amounts shown due on such Tax Returns
on or before the Effective Time have been or will be paid on or before such
date. The Target Financial Statements (i) fully accrue all actual and contingent
liabilities for Taxes (whether or not shown as due on the Tax Returns) with
respect to all periods through the Target Balance Sheet Date and Target has not
and will not incur any Tax liability in excess of the amount reflected on the
Target Balance Sheet included in the Target Financial Statements with respect to
such periods, other than Taxes incurred in the ordinary course of its business
following the Target Balance Sheet, and (ii) fully accrues in accordance with
GAAP all material liabilities for Taxes payable after the Target Balance Sheet


                                       15
<PAGE>

Date with respect to all transactions and events occurring on or prior to such
date. All information set forth in the notes to the Target Financial Statements
relating to Tax matters is true and accurate in all material respects. With
respect to periods after the Target Balance Sheet Date, no Tax liability has
been incurred by Target which exceeds the amount of Tax liability that would
have been incurred in the ordinary course of business of Target during such
period had Target not been a member of an affiliated, consolidated, combined or
unitary group for Tax purposes during any part of such period, and adequate
provision has been made by Target for all Taxes since that date on at least a
quarterly basis. Other than with respect to (i) the amount of Taxes reflected in
the reserve for Tax liability reflected on the Target Balance Sheet that is part
of the Target Financial Statements, and (ii) the amount of Taxes that would have
been incurred by Target in the ordinary course of business between the Target
Balance Sheet Date and the Closing had Target not been a member of an
affiliated, consolidated, combined or unitary group for Tax purposes during any
part of such period, Principal Stockholder has the sole and absolute liability
with respect to the payment of any Taxes imposed on Target attributable to any
Tax year or portion thereof ending on or before the Closing (or for any Tax year
beginning before and ending after the Closing to the extent allocable to the
portion of such period beginning before and ending on the Closing) and Principal
Stockholder shall pay all such Taxes when due. If Principal Stockholder pays any
Tax that is attributable to the period between the Target Balance Sheet Date and
the Closing and would have been incurred by Target in the ordinary course of
business had Target not been a member of an affiliated, consolidated, combined
or unitary group for Tax purposes during any part of such period, then Target
shall reimburse Principal Stockholder for the amount of such Tax within 21
business days after receipt from Principal Stockholder of a written claim for
such reimbursement together with a reasonably detailed written computation of
the amount thereof, unless Target reasonably disagrees with such computation or
other basis for such claim in which case, if the parties cannot come to
agreement within 30 days, the dispute shall be submitted to arbitration in
accordance with Section 8.8 hereof. If Principal Stockholder pays any other Tax
attributable to Target as to any Tax year or portion thereof ending on or before
the Target Balance Sheet Date (or for any Tax year beginning before and ending
after the Target Balance Sheet Date to the extent allocable to the portion of
such period beginning before and ending on the Target Balance Sheet Date), then
up to the amount of the reserve for Tax liability reflected on the Target
Balance Sheet that is part of the Target Financial Statements (reduced by (i)
prior reimbursements paid to Principal Stockholder pursuant to this sentence,
(ii) amounts previously paid by Target or Acquiror to a Tax authority in respect
of a Tax otherwise reimbursable pursuant to this sentence and, (iii) amounts
previously paid or reasonably expected to be paid in respect of Taxes covered by
or relating to periods covered by such Tax reserve), then Target shall reimburse
Principal Stockholder for the amount of such Tax within 21 business days after
receipt from Principal Stockholder of a written claim for such reimbursement
together with a reasonably detailed written computation of the amount thereof
unless Target reasonably disagrees with such computation or other basis for such
claim in which case, if the parties cannot come to agreement, the dispute shall
be submitted to arbitration in accordance with Section 8.8 hereof.

                (b) Target has previously provided or made available to Acquiror
copies of all income, franchise, and sales Tax Returns as filed with the
appropriate Tax authority, and, as reasonably requested by Acquiror, prior to or
following the date hereof, presently existing information statements and
reports. Target has withheld and paid to the applicable financial institution or
Tax authority all amounts required to be withheld. To the best knowledge of


                                       16
<PAGE>

Target, no Tax Returns filed with respect to Taxable years of Target through the
Taxable year ended December 31, 1999 in the case of the United States, have been
examined and closed. Target (or any member of any affiliated or combined group
of which Target has been a member) has not granted any extension or waiver of
the limitation period applicable to any Tax Returns that is still in effect.
There is no material claim, audit, action, suit, proceeding, or (to the
knowledge of Target or the Principal Stockholder) investigation now pending or
(to the knowledge of Target or the Principal Stockholder) threatened against or
with respect to Target in respect of any Tax or assessment. No notice of
deficiency or similar document of any Tax authority has been received by Target,
and there are no liabilities for Taxes (including liabilities for interest,
additions to Tax and penalties thereon and related expenses) with respect to the
issues that have been raised (and are currently pending) by any Tax authority
that could, if determined adversely to Target, materially and adversely affect
the liability of Target for Taxes. There are no liens for Taxes (other than for
current Taxes not yet due and payable) upon the assets of Target. Target is in
full compliance with all the terms and conditions of any Tax exemptions or other
Tax-sharing agreement or order of a foreign government and the consummation of
the Merger will not have any adverse effect on the continued validity and
effectiveness of any such Tax exemption or other Tax-sharing agreement or order.
Neither Target nor any person on behalf of Target has entered into or will enter
into any agreement or consent pursuant to the collapsible corporation provisions
of Section 341(f) of the Code (or any corresponding provision of state, local or
foreign income tax law) or agreed to have Section 341(f)(2) of the Code (or any
corresponding provision of state, local or foreign income tax law) apply to any
disposition of any asset owned by Target. None of the assets of Target is
property that Target is required to treat as being owned by any other person
pursuant to the so-called "safe harbor lease" provisions of former Section
168(f)(8) of the Code. None of the assets of Target directly or indirectly
secures any debt the interest on which is tax-exempt under Section 103(a) of the
Code. None of the assets of Target is "tax-exempt use property" within the
meaning of Section 168(h) of the Code. Target has not made and will not make a
deemed dividend election under Treas. Reg. Section 1.1502-32(f)(2) or a consent
dividend election under Section 565 of the Code. Target has never been a party
to any transaction intended to qualify under Section 355 of the Internal Revenue
Code or any corresponding provision of state law. Target has not participated in
(and will not participate in) an international boycott within the meaning of
Section 999 of the Code. No Target stockholder is other than a United States
person within the meaning of the Code. Target does not have and has not had a
permanent establishment in any foreign country, as defined in any applicable tax
treaty or convention between the United States of America and such foreign
country and Target has not engaged in a trade or business within any foreign
country. Target has never elected to be treated as an S-corporation under the
Code or any corresponding provision of federal or state law. All material
elections with respect to Target's Taxes made during the fiscal year ending
December 31, 1999 are reflected on the Target Tax Returns for such period,
copies of which have been provided or made available to Acquiror. After the date
of this Agreement and prior to the Effective Time, no material election with
respect to Taxes will be made without the prior written consent of Acquiror,
which consent not to be unreasonably withheld. Target is not party to any joint
venture, partnership, or other arrangement or contract which could be treated as
a partnership for federal income tax purposes. Target is not currently and never
has been subject to the reporting requirements of Section 6038A of the Code.
There is no agreement, contract or arrangement to which Target is a party that
could, individually or collectively, result in the payment of any amount that


                                       17
<PAGE>

would not be deductible by reason of Sections 280G (as determined without regard
to Section 280G(b)(4), 162 (other than 162(a)) or 404 of the Code. Target is not
a party to or bound by any Tax indemnity, Tax sharing or Tax allocation
agreement (whether written or unwritten or arising under operation of federal
law as a result of being a member of a group filing consolidated Tax returns,
under operation of certain state laws as a result of being a member of a unitary
group, or under comparable laws of other states or foreign jurisdictions) which
includes a party other than Target nor does Target owe any amount under any such
Agreement. Target has previously provided or made available to Acquiror copies
of all income, franchise, and sales Tax Returns as filed with the appropriate
Tax authority, and, as reasonably requested by Acquiror, prior to or following
the date hereof, presently existing information statements and reports. Target
is not, and has not been, a United States real property holding corporation (as
defined in Section 897(c)(2) of the Code) during the applicable period specified
in Section 897(c)(1)(A)(ii) of the Code. Other than by reason of the Merger,
Target has not been and will not be required to include any material adjustment
in Taxable income for any Tax period (or portion thereof) pursuant to Sections
481 or 263A of the Code or any comparable provision under state or foreign Tax
laws as a result of transactions, events or accounting methods employed prior to
the Merger.

Financial Statements.

                (d) Target is not obligated and upon consummation of the Merger

                (e) There are no pending or, to Target's knowledge, threatened
claims or actions (or basis therefor) against Target under any worker's

                (f) Target has complied in all material respects with the
verification requirements and the record-keeping requirements of the Immigration
Reform and Control Act of 1986 ("IRCA"); and there have not been any

complaint, except for those complaints that if decided against Target would not
have a Material Adverse Effect on Target.

                (g) Target has not received or been notified of any complaint by
any employee, applicant, union or other party of any discrimination or other
conduct forbidden by law or contract, and to the knowledge of Target and the

the date hereof and otherwise has complied in all material respects in its
hiring, employment, promotion, termination and other labor practices with all
applicable federal and state law and regulations, including without limitation
those within the jurisdiction of the United States Equal Employment Opportunity
Commission, United States Department of Labor and state and local human rights
or civil rights agencies, except where such failure to file or non-compliance
would not have a Material Adverse Effect on Target. Target has filed and shall
file any such reports and information that are required to be filed under

otherwise (an "Employee Obligation") that could reasonably be expected to
interfere with the use of his or her best efforts to promote the interests of

business as conducted or proposed to be conducted. Neither the execution nor
delivery of this Agreement nor the conduct of Target's business as conducted or
proposed to be conducted, will, to Target's knowledge, conflict with or result
in a breach of the terms, conditions or provisions of, or constitute a default
under, any Employee Obligation, where such breach or default would have a
Material Adverse Effect on Target.

                                  ARTICLE II-A

           REPRESENTATIONS AND WARRANTIES OF THE PRINCIPAL STOCKHOLDER

        In addition to the joint and several representations made in Article II
hereof, the Principal Stockholder hereby represents and warrants that:

        2A.1    Authority.

                (a) The Principal Stockholder has all requisite power, corporate
or otherwise, and authority to enter into this Agreement, the Registration
Rights Agreement and the Escrow Agreement and to consummate the transactions
contemplated hereby and thereby. The execution and delivery of this Agreement
and the other Transaction Documents and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by all necessary
corporate action on the part of the Principal Stockholder. This Agreement and
other Transaction Documents have been duly executed and delivered by the
Principal Stockholder and constitute the valid and binding obligations of the
Principal Stockholder enforceable against the Principal Stockholder in
accordance with their terms.

                (b) The execution and delivery of this Agreement and the other
Transaction Documents by the Principal Stockholder do not, and the consummation
of the transactions contemplated hereby and thereby 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 (i) any provision of
the Certificate of Incorporation or Bylaws of the Principal Stockholder, as
amended, or (ii) any material contract or any material permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to the Principal Stockholder or any of its properties or
assets, except where such conflict, violation, default, right or loss would not
result in the prevention or material delay of the transactions contemplated by
this Agreement.

        2A.2    Title to Stock. The Principal Stockholder has good and valid
title to the Target Common Stock held by it, free and clear of all liens,
encumbrances, equities or claims. There are no outstanding subscriptions,
options, warrants, puts, calls, rights, exchangeable or convertible securities
or other commitments or agreements of any character relating to the issued or
unissued capital stock or other securities of any such subsidiary, or otherwise
obligating the Principal Stockholder or any such subsidiary to issue, transfer,
sell, purchase, redeem or otherwise acquire any such securities.

        2A.3    No Distribution. The Principal Stockholder is acquiring the
shares for investment for its own account, not as a nominee or agent, and not
with the view to, or for resale in connection with, any distributions thereof,
except in compliance with applicable securities laws. It understands that the
shares of Acquiror Common Stock have not been, and will not be, registered under
the Securities Act by reason of a specific exemption from the registration
provisions of the Securities Act, the availability of which depends upon, among
other things, the bona fide nature of the investment intent and the accuracy of


                                       25
<PAGE>

the Principal Stockholder's representations as expressed herein.

        2A.4    Sophistication of Principal Stockholder. The Principal
Stockholder understands that Acquiror has a limited financial and operating
history and that an investment in Acquiror involves substantial risks. The
Principal Stockholder further understands that the purchase of the shares of
Acquiror Common Stock is a highly speculative investment. The Principal
Stockholder is able, without impairing the Principal Stockholder's financial
condition, to hold the shares of Acquiror Common Stock and for an indefinite
period of time and to suffer a complete loss of the Principal Stockholder's
investment.

        2A.5    Accredited Investor. The Principal Stockholder is an accredited
investor within the meaning of Securities and Exchange Commission ("SEC") Rule
501 of Regulation D, as presently in effect.

                                   ARTICLE III

            REPRESENTATIONS AND WARRANTIES OF ACQUIROR AND MERGER SUB

                Acquiror and Merger Sub, jointly and severally, represent and
warrant to Target that the statements contained in this Article III are true and
correct, except as set forth in the disclosure schedule delivered by Acquiror to
Target prior to the execution and delivery of this Agreement, as amended in
accordance with Section 5.8(b), subject to the last sentence of Section 5.8(b)
(the "Acquiror Disclosure Schedule"). The Acquiror Disclosure Schedule shall be
arranged in paragraphs corresponding to the numbered and lettered paragraphs
contained in this Article III, and the disclosure in any paragraph shall qualify
only the corresponding paragraph in this Article III. Any reference in this
Article III to an agreement being "enforceable" shall be deemed to be qualified
to the extent such enforceability is subject to (i) laws of general application
relating to bankruptcy, insolvency, moratorium and the relief of debtors, and
(ii) the availability of specific performance, injunctive relief and other
equitable remedies.

        3.1     Organization, Standing and Power. Each of Acquiror and its
subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization. Each of Acquiror
and its subsidiaries has the corporate power to own its properties and to carry
on its business as now being conducted and as proposed to be conducted and is
duly qualified to do business and is in good standing in each jurisdiction in
which the failure to be so qualified and in good standing would have a Material
Adverse Effect on Acquiror. Acquiror has delivered a true and correct copy of
the Certificate of Incorporation and Bylaws or other charter documents, as
applicable, of Acquiror and its subsidiaries, each as amended to date, to
Target. Neither Acquiror nor Merger Sub (or any other subsidiary) is in
violation of any of the provisions of its Certificate of Incorporation or Bylaws
or equivalent organizational documents. Acquiror is the owner of all outstanding
shares of capital stock of each of its subsidiaries and all such shares are duly
authorized, validly issued, fully paid and nonassessable. All of the outstanding
shares of capital stock of each such subsidiary are owned by Acquiror free and
clear of all liens, charges, claims or encumbrances or rights of others. There
are no outstanding subscriptions, options, warrants, puts, calls, rights,


                                       26
<PAGE>

exchangeable or convertible securities or other commitments or agreements of any
character relating to the issued or unissued capital stock or other securities
of any such subsidiary, or otherwise obligating Acquiror or any such subsidiary
to issue, transfer, sell, purchase, redeem or otherwise acquire any such
securities. Except as disclosed in the Acquiror SEC Documents (as defined in
Section 3.4), Acquiror does not directly or indirectly own any equity or similar
interest in, or any interest convertible or exchangeable or exercisable for, any
equity or similar interest in, any corporation, partnership, joint venture or
other business association or entity.

        3.2     Capital Structure. The authorized capital stock of Acquiror
consists of 200,000,000 shares of Common Stock, $0.001 par value, and 10,000,000
shares of Preferred Stock, $0.001 par value, of which there were issued and
outstanding as of the close of business on the date hereof, 29,102,124 shares of
Common Stock and no shares of Preferred Stock. There are no other outstanding
shares of capital stock or voting securities of Acquiror and no outstanding
commitments to issue any shares of capital stock or voting securities after the
date of this Agreement other than pursuant to the exercise of options issued
under the 1999 Stock Incentive Plan (the "Acquiror Stock Option Plan"),
Acquiror's Employee Stock Purchase Plan and options granted outside the Acquiror
Stock Option Plan. The authorized capital stock of Merger Sub consists of 1,000
shares of Common Stock, $0.001 par value, all of which are issued and
outstanding and are held by Acquiror. All outstanding shares of Acquiror and
Merger Sub have been duly authorized, validly issued, fully paid and are
nonassessable and free of any liens or encumbrances other than any liens or
encumbrances created by or imposed upon the holders thereof and are not subject
to preemptive rights, rights of first refusal or other similar rights created by
statute, the Certificate of Incorporation or Bylaws of Acquiror or Merger Sub or
any agreement to which Acquiror or Merger Sub is a party or by which it is
bound. As of the date hereof, Acquiror had reserved (i) 6,655,600 shares of
Common Stock for issuance to employees, directors and independent contractors
pursuant to the Acquiror Stock Option Plan, of which approximately 556,122
shares had been issued pursuant to option exercises, and approximately 5,667,751
shares were subject to outstanding, unexercised options, (ii) 750,000 shares of
Common Stock pursuant to Acquiror's Employee Stock Purchase Plan, of which
approximately 85,337 shares had been issued pursuant to stock purchases, and
(iii) 4,140,340 shares of Acquiror Common Stock upon the exercise of outstanding
options granted outside the Acquiror Stock Option Plan. Other than as set forth
above and the commitment to issue shares of Common Stock pursuant to this
Agreement, there are no other options, warrants, calls, rights, commitments or
agreements of any character to which Acquiror or Merger Sub is a party or by
which either of them is bound obligating Acquiror or Merger Sub to issue,
deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold,
repurchased or redeemed, any shares of the capital stock of Acquiror or Merger
Sub or obligating Acquiror or Merger Sub to grant, extend or enter into any such
option, warrant, call, right, commitment or agreement. The shares of Acquiror
Common Stock to be issued pursuant to the Merger will be duly authorized,
validly issued, fully paid, and non-assessable, will not be subject to any
preemptive or other statutory right of stockholders, will be issued in
compliance with applicable U.S. Federal and state securities laws and will be
free of any liens or encumbrances other than any liens or encumbrances created
by or imposed upon the holders thereof. There are no contracts, commitments or
agreements relating to voting, registration, purchase or sale of Acquiror's
capital stock (i) between or among Acquiror and any of its stockholders or (ii)
to the best of Acquiror's knowledge, between or among any of Acquiror's
stockholders or between any of Acquiror's stockholders and any third party. All
outstanding shares of Acquiror Common Stock, options, warrants and other
Acquiror securities were issued in compliance with all applicable federal and


                                       27
<PAGE>

state securities laws, except where the failure to so comply would not have a
Material Adverse Effect on Acquiror.

        3.3     Authority.

                (a) Each of Acquiror and Merger Sub has all requisite corporate
power and authority to enter into this Agreement and the other Transaction
Documents and to consummate the transactions contemplated hereby and thereby.
The execution and delivery of this Agreement and the other Transaction Documents
and the consummation of the transactions contemplated hereby and thereby have
been duly authorized by all necessary corporate action on the part of each of
Acquiror and Merger Sub, subject only to the approval of the Merger by
Acquiror's stockholders as contemplated by Section 6.1(a). This Agreement and
the other Transaction Documents have been duly executed and delivered by each of
Acquiror and Merger Sub and constitute the valid and binding obligations of each
of Acquiror and Merger Sub enforceable against Acquiror and Merger Sub in
accordance with their terms. Without limiting the generality of the forgoing,
the Acquiror Board of Directors has unanimously (i) approved the Merger, and
(ii) has not withdrawn or modified such approval or resolution to recommend.

                (b) The execution and delivery of this Agreement and the other
Transaction Documents do not, and the consummation of the transactions
contemplated hereby and thereby 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 a benefit under (i) any provision of the Certificate
of Incorporation or Bylaws of Acquiror or any of its subsidiaries, as amended,
or (ii) any agreement contained as an exhibit to any Acquiror SEC Documents (as
defined) or any instrument, permit, concession, franchise, license, judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to
Acquiror or any of its subsidiaries or their properties or assets, except for
such conflicts, violations, defaults, rights or losses which would not have a
Material Adverse Effect on Acquiror.

                (c) No consent, approval, order or authorization of, or
registration, declaration or filing with, any Governmental Entity, is required
by or with respect to Acquiror or any of its subsidiaries in connection with the
execution and delivery of this Agreement or the other Transaction Documents by
Acquiror or the consummation by Acquiror of the transactions contemplated hereby
or thereby, except for (i) the filing of the Agreement of Merger, together with
the required officers' certificates, as provided in Section 1.2, (ii) the filing
of the proxy statement, (iii) the filing of a Form 8-K with the SEC and National

and the securities laws of any foreign country, (v) such filings as may be
required under HSR, (vi) the filing with the Nasdaq National Market of a
Notification Form for Listing of Additional Shares, with respect to the shares
of Acquiror Common Stock issuable upon conversion of the Target Capital Stock in
the Merger and upon exercise of the options under the Target Stock Option Plan
assumed by Acquiror, and (vii) such other consents, authorizations, filings,
approvals and registrations which, if not obtained or made, would not have a
Material Adverse Effect on Acquiror and would not prevent, materially alter or
delay any of the transactions contemplated by this Agreement.

        3.4     SEC Documents; Financial Statements. Acquiror has furnished to
Target a true and complete copy of each statement, report, registration
statement (with the prospectus in the form filed pursuant to Rule 424(b) of the
Securities Act, definitive proxy statement, and other filing filed with the SEC
by Acquiror since its inception, and, prior to the Effective Time, Acquiror will
have furnished Target with true and complete copies of any additional documents
filed with the SEC by Acquiror prior to the Effective Time (collectively, the
"Acquiror SEC Documents"). In addition, Acquiror has made available to Target
all exhibits to the Acquiror SEC Documents filed prior to the date hereof, and
will promptly make available to Target all exhibits to any additional Acquiror
SEC Documents filed prior to the Effective Time. All documents required to be
filed as exhibits to the Target SEC Documents have been so filed, and all
material contracts so filed as exhibits are in full force and effect, except
those which have expired in accordance with their terms, and neither Acquiror
nor any of its subsidiaries is in default thereunder. Acquiror has filed all
Acquiror SEC Documents required to be filed and, as of their respective filing
dates, the Acquiror SEC Documents complied in all material respects with the
requirements of the Securities Exchange Act of 1934, as amended (the "Exchange
Act") and the Securities Act, and none of the Acquiror SEC Documents contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements made therein,
in light of the circumstances in which they were made, not misleading, except to
the extent corrected by a subsequently filed Acquiror SEC Document. Acquiror has
heretofore made, and hereafter will make, available to Principal Stockholder a
complete and correct copy of any amendments or modifications that are required
to be filed with the SEC but have not yet been filed by Acquiror with the SEC
pursuant to the Exchange Act. The financial statements of Acquiror, including
the notes thereto, included in the Acquiror SEC Documents (the "Acquiror
Financial Statements") were complete and correct in all material respects as of
their respective dates, complied as to form in all material respects with
applicable accounting requirements and with the published rules and regulations
of the SEC with respect thereto as of their respective dates, and have been
prepared in accordance with GAAP applied on a basis consistent throughout the
periods indicated and consistent with each other (except as may be indicated in
the notes thereto or, in the case of unaudited statements included in Quarterly
Reports on Form 10-Qs, as permitted by Form 10-Q). The Acquiror Financial
Statements fairly present the consolidated financial condition and operating
results of Acquiror and its subsidiaries at the dates and during the periods
indicated therein (subject, in the case of unaudited statements, to normal,
recurring year-end adjustments).

        3.5     Absence of Certain Changes. Since June 30, 2000 (the "Acquiror
Balance Sheet Date"), Acquiror has conducted its business in the ordinary course
consistent with past practice and there has not occurred: (i) any material
adverse change, or any event likely to result in such change, to the business,
financial condition or results of operation or the properties, assets and
liabilities of Acquiror; (ii) any acquisition, sale or transfer of any material
asset of Acquiror, (iii) any contract entered into by Acquiror, other than as
provided to Target, or any amendment or termination of, or default under, any
contract to which Acquiror is a party or by which it is bound that has resulted,
or is reasonably likely to result, in a Material Adverse Effect on Acquiror;
(iv) any amendment or change to the Certificate of Incorporation or Bylaws of
Acquiror; (v) capital expenditures or capital commitments by Acquiror exceeding
$500,000 individually or $2,500,000 in the aggregate; (vi) any change in
accounting methods or practices (including any change in depreciation or
amortization policies or rates) by Acquiror or any revaluation by Acquiror of


                                       29
<PAGE>

any of its assets; or (vii) any agreement by Acquiror to do any of the things
described in the preceding clauses (i) through (vi).

        3.6     Litigation. Except as disclosed in the Acquiror SEC Documents,
there is no private or governmental action, suit, proceeding, claim, arbitration
or investigation pending before any agency, court or tribunal, foreign or
domestic, or, to the knowledge of Acquiror or any of its subsidiaries,
threatened against Acquiror or any of its subsidiaries or any of their
respective properties or any of their respective officers or directors (in their
capacities as such) that, individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect on Acquiror. There is no judgment,
decree or order against Acquiror or any of its subsidiaries or, to the knowledge
of Acquiror or any of its subsidiaries, any of their respective directors or
officers (in their capacities as such) that could prevent, enjoin, or materially
delay any of the transactions contemplated by this Agreement, or that could
reasonably be expected to have a Material Adverse Effect on Acquiror. Acquiror
does not have any plans to initiate any litigation, arbitration or other
proceeding against any third party, other than for routine collection on bills.

        3.7     [Intentionally Omitted].

        3.8     Compliance with Laws. Acquiror has complied with, is not in
violation of, and has not received any notices of violation with respect to, any
federal, state, local or foreign statute, law or regulation with respect to the
conduct of its business, or the ownership or operation of its business, except
for such violation or failures to comply as could not be reasonably expected to
have a Material Adverse Effect on Acquiror.

        3.9     Brokers' and Finders' Fees. Acquiror has not incurred, nor will
it incur, directly or indirectly, any liability for brokerage or finders' fees
or agents' commissions or investment bankers' fees or any similar charges in
connection with this Agreement or any transaction contemplated hereby.

        3.10    Vote Required. The votes of the holders of Acquiror's Capital
Stock are not necessary to approve this Agreement and the transactions
contemplated hereby.

        3.11    No Breach of Material Contracts. The Acquiror has performed all
of the material obligations required to be performed by it and is entitled to
all benefits under, and is not in default in respect of any contract of
Acquiror, except where the failure to so perform or the failure to be entitled
to all benefits or such default would have a Material Adverse Effect on
Acquiror. Each of the Acquiror Material Contracts is in full force and effect,
and there exists no default or event of default or event, occurrence, condition
or act, with respect to Acquiror or Acquiror's knowledge with respect to the
other contracting party, or otherwise that, with or without the giving of
notice, the lapse of the time or happening of any other event or conditions,
could reasonably be expected to (A) become a default or event of default under
any Acquiror Material Contract which default or event of default could
reasonably be expected to have a Material Adverse Effect on Acquiror or (B)
result in the loss or expiration of any material right or option by Acquiror (or
the gain thereof by any third party) under any Acquiror Material Contract, which
loss or expiration would have a Material Adverse Effect on Acquiror or (C)
result in the release, disclosure or delivery to any third party of any party of


                                       30
<PAGE>

the Source Materials of Acquiror (as defined in Section 2.26(k)). True, correct

                (a) From and after the date of this Agreement until the earlier
of the Effective Time or the termination of this Agreement, Target shall not,

proposal or offer for a merger, consolidation, business combination, sale of all
or substantially all of the assets, sale of shares of capital stock (including
without limitation by way of a tender offer) or similar transactions involving
Target, other than the transactions contemplated by this Agreement (any of the

"Takeover Proposal"), (ii) engage in negotiations or discussions concerning, or
provide any non-public information to any person or entity relating to, any
Takeover Proposal, or (iii) agree to, approve or recommend any Takeover

Proposal or any request for information in connection with a Takeover Proposal
or for access to the properties, books or records of Target by any person or
entity that informs Target that it is considering making, or has made, a
Takeover Proposal prior to the earlier of the Effective Time or the termination
of this Agreement. Such notice shall be made orally and in writing and shall
indicate in reasonable detail the identity of the offeror and the terms and
conditions of such proposal, inquiry or contact.

        5.2     [Intentionally Omitted].

        5.3     Stockholder Meetings or Consent Solicitations. Target shall
promptly after the date hereof take all actions necessary to either (i) call a
meeting of its stockholders to be held for the purpose of voting upon this
Agreement and the Merger or (ii) commence a consent solicitation to obtain such
approvals. Target shall use all reasonable efforts to solicit from their
stockholders proxies or consents in favor of such matters as promptly as
reasonably practicable.

        5.4     Access to Information.

                (a) Each of Acquiror and Target shall afford the other party and
its accountants, counsel and other representatives, reasonable access during
normal business hours during the period prior to the Effective Time to (i) all
of its and its subsidiaries' properties, books, contracts, commitments and
records, and (ii) all other information concerning its business, properties and

agrees to provide to the other party and its accountants, counsel and other
representatives copies of internal financial statements promptly upon request.

                (b) Subject to compliance with applicable law, from the date

regular and frequent basis with one or more representatives of the other party

to report operational matters of materiality and the general status of ongoing
operations.

                (c) No information or knowledge obtained in any investigation
pursuant to this Section 5.4 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.

        5.5     Confidentiality. The parties acknowledge that Acquiror and
Target have previously executed a non-disclosure agreement dated August 11, 2000
(the "Confidentiality Agreement"), which Confidentiality Agreement shall
continue in full force and effect in accordance with its terms.

        5.6     Public Disclosure. Unless otherwise permitted by this Agreement,
Acquiror and Target shall consult with each other before issuing any press
release or otherwise making any public statement or making any other public (or
non-confidential) disclosure (whether or not in response to an inquiry)
regarding the terms of this Agreement and the transactions contemplated hereby,
and neither shall issue any such press release or make any such statement or
disclosure without the prior approval of the other (which approval shall not be
unreasonably withheld), except as may be required by Acquiror or the Principal
Stockholder to comply with the rules and regulations of the SEC or any
obligations pursuant to any listing agreement with any national securities
exchange.

        5.7     Consents; Cooperation.

                (a) Each of Acquiror and Target shall promptly apply for or
otherwise seek, and use its reasonable best efforts to obtain, all consents and
approvals required to be obtained by it for the consummation of the Merger,
including those required under HSR, and shall use its reasonable best efforts to
obtain all necessary consents, waivers and approvals under any of its material
contracts in connection with the Merger for the assignment thereof or otherwise.
The parties hereto will consult and cooperate with one another, and consider in
good faith the views of one another, in connection with any analyses,
appearances, presentations, memoranda, briefs, arguments, opinions and proposals
made or submitted by or on behalf of any party hereto in connection with
proceedings under or relating to HSR or any other federal or state antitrust or
fair trade law.

                (b) Each of Acquiror and Target shall use all commercially
reasonable efforts to resolve such objections, if any, as may be asserted by any
Governmental Entity with respect to the transactions contemplated by this
Agreement under the HSR, the Sherman Act, as amended, the Clayton Act, as
amended, the Federal Trade Commission Act, as amended, and any other Federal,
state or foreign statutes, rules, regulations, orders or decrees that are
designed to prohibit, restrict or regulate actions having the purpose or effect
of monopolization or restraint of trade (collectively, "Antitrust Laws"). In
connection therewith, if any administrative or judicial action or proceeding is
instituted (or threatened to be instituted) by any Governmental Entity
challenging any transaction contemplated by this Agreement as violative of any
Antitrust Law, each of Acquiror and Target shall cooperate and use all
commercially reasonable efforts vigorously to contest and resist any such action
or proceeding and to have vacated, lifted, reversed, or overturned any decree,
judgment, injunction or other order, whether temporary, preliminary or permanent


                                       36
<PAGE>

(each an "Order"), that is in effect and that prohibits, prevents, or restricts
consummation of the Merger or any such other transactions, unless by mutual
agreement Acquiror and Target decide that litigation is not in their respective
best interests. Notwithstanding the provisions of the immediately preceding
sentence, it is expressly understood and agreed that neither Target nor Acquiror
shall have any obligation to litigate or contest any administrative or judicial
action or proceeding or any Order beyond the earlier of (i) December 31, 2000 or
(ii) the date of a ruling preliminarily enjoining the Merger issued by a court
of competent jurisdiction. Each of Acquiror and Target shall use all
commercially reasonable efforts to take such action as may be required to cause
the expiration of the notice periods under the HSR or other Antitrust Laws with
respect to such transactions as promptly as possible after the execution of this
Agreement.

                (c) Notwithstanding the foregoing, neither Acquiror nor Target
shall be required to agree, as a condition to any approval, to divest itself of
or hold separate any subsidiary, division or business unit which is material to
the business of such party and its subsidiaries, taken as a whole, or the
divestiture or holding separate of which would be reasonably likely to have a
Material Adverse Effect on (A) the business, properties, assets, liabilities,
financial condition or results of operations of such party and its subsidiaries,
taken as a whole or (B) the benefits intended to be derived as a result of the
Merger.

        5.8     Update Disclosure; Breaches. From and after the date of this
Agreement until the Effective Time, (a) each party hereto shall reasonably
promptly notify the other party in writing of (i) the occurrence or
non-occurrence of any event which would be likely to cause any condition to the
obligations of any party to effect the Merger and the other transactions
contemplated by this Agreement not to be satisfied, or (ii) the failure of a
party hereto, as the case may be, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it pursuant to this
Agreement which would be likely to result in any condition to the obligations of
any party to effect the Merger and the other transactions contemplated by this
Agreement not to be satisfied, and (b) each party shall reasonably promptly
notify the other party, by written update to its Disclosure Schedule, of any
event, change, effect, matter or state of facts occurring after the date of this
Agreement, which would, if occurring prior to the date of this Agreement, have
been required to have been disclosed in the Disclosure Schedules to make such
party's representations and warranties true and correct. The delivery of any
notice pursuant to this Section 5.8 shall not cure any breach of any
representation or warranty requiring disclosure of such matter prior to the date
of this Agreement or otherwise limit or affect the remedies available hereunder
to the party receiving such notice, provided that such party, within ten days
after receipt of such notice, advises the other party of its objection to the
matter disclosed in such notice and the nature of such objection.

        5.9     Intentionally Omitted.

        5.10    Indemnification.

                (a) From and after the Effective Time, Acquiror and the
Surviving Corporation jointly and severally shall indemnify, defend and hold
harmless each person who is now, or has been at any time prior to the date of
this Agreement or who becomes prior to the Effective Time, an officer, director
or employee of Target or any of its subsidiaries (the "Indemnified Parties") in


                                       37
<PAGE>

respect of acts or omissions occurring on or prior to the Effective Time to the
fullest extent permitted under applicable law and as provided under Target's
Certificate of Incorporation, Bylaws and indemnification agreements in effect on
the date hereof. Each Indemnified Person is intended to be a third party
beneficiary of this Section 5.10 and may specifically enforce its terms. This
Section 5.10 shall not limit or otherwise adversely affect any rights any
Indemnified Person may have under any agreement with Acquiror or under
Acquiror's Certificate of Incorporation or bylaws as presently in effect or as
provided by Delaware law.

                (b) From and after the Effective Time, Acquiror shall, or shall
cause the Surviving Corporation to, fulfill and honor in all respects the
obligations of Target pursuant to any indemnification agreements between Target
and its directors and officers as of or prior to the date hereof and any
indemnification provisions under Target's certificate of incorporation or bylaws
as in effect immediately prior to the Effective Time.

                (c) If Acquiror or the Surviving Corporation or any of their
respective successors or assigns (i) consolidates with or merges into any other
person or entity and shall not be the continuing or surviving person of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person or entity, then and in each such case,
proper provision shall be made so that such successors or assigns of Acquiror or
the Surviving Corporation, as the case may be, shall assume the obligations set
forth in this Section 5.10.

        5.11    Further Assurances. Principal Stockholder agrees to assist
Target to further evidence, record and perfect all assignments and licenses
contemplated by Section 6.3(l), and to perfect, obtain, maintain, enforce, and
defend any such rights assigned or licensed.

        5.12    Legal Requirements. Each of Acquiror and Target will, and will
cause their respective subsidiaries to, take all reasonable actions necessary to
comply promptly with all legal requirements which may be imposed on them with
respect to the consummation of the transactions contemplated by this Agreement
and will promptly cooperate with and furnish information to any party hereto
necessary in connection with any such requirements imposed upon such other party
in connection with the consummation of the transactions contemplated by this
Agreement and will take all reasonable actions necessary to obtain (and will
cooperate with the other parties hereto in obtaining) any consent, approval,
order or authorization of, or any registration, declaration or filing with, any
Governmental Entity or other person, required to be obtained or made in
connection with the taking of any action contemplated by this Agreement.

        5.13    Tax-Free Reorganization. Neither Target, Acquiror nor Merger Sub
will, either before or after consummation of the Merger, take any action which,
to the knowledge of such party, would cause the Merger to fail to constitute a
"reorganization" within the meaning of Code Section 368.

        5.14    Blue Sky Laws. Acquiror shall take such steps as may be
necessary to comply with the securities and blue sky laws of all jurisdictions
which are applicable to the issuance of the Acquiror Common Stock in connection
with the Merger. Target shall use its reasonable best efforts to assist Acquiror
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 Acquiror
Common Stock in connection with the Merger.


                                       38

        5.15    Stock Options.

                (a) At the Effective Time, the Target Stock Option Plan and each
Target Option, whether vested or unvested, shall be assumed by Acquiror, and
Target's repurchase right with respect to any unvested option shares granted
under the Target Stock Option Plan shall be assigned to Acquiror and Acquiror
shall thereafter comply with the terms of the Target Stock Option Plan with
respect to such assumed Target Options. On the Closing Date, Target shall
deliver to Acquiror an updated Option Schedule current as of such date. Each
Target Option so assumed by Acquiror under this Agreement shall continue to
have, and be subject to, the same terms and conditions set forth in the Target
Stock Option Plan immediately prior to the Effective Time, except that (i) such
Target Option shall be exercisable for that number of whole shares of Acquiror
Common Stock equal to the product of the number of shares of Target Common Stock
that were issuable upon exercise of such Target Option immediately prior to the
Effective Time multiplied by the Option Exchange Ratio (as defined below) and
rounded down to the nearest whole number of shares of Acquiror Common Stock,
(ii) the per share exercise price for the shares of Acquiror Common Stock
issuable upon exercise of such Target Option shall be equal to the quotient
determined by dividing the exercise price per share of Target Common Stock at
which such option was exercisable immediately prior to the Effective Time by the
Option Exchange Ratio, rounded down to the nearest whole cent. The vesting of
any unvested Target Options will not accelerate as a result of the execution of
this Agreement or the consummation of the transactions contemplated hereby.
Within 45 business days after the Effective Time, Acquiror will issue to each
person who, immediately prior to the Effective Time was a holder of a Target
Option a document evidencing the foregoing assumption of such Target Option by
Acquiror, and within 45 business days after an adjustment to the Option Exchange
Ratio as a result of the provisions of Annex A hereto, Acquiror will issue to
each such person a revised document reflecting the adjusted Option Exchange
Ratio. The "Option Exchange Ratio" shall equal the quotient obtained by dividing
the Acquiror Stock Subject to Target Options by the number of shares of Target
Common Stock issuable pursuant to the exercise of all Target Options. The
"Acquiror Stock Subject to Target Options" shall equal the quotient obtained by
dividing the Initial Target Optionholder Consideration plus the Additional
Optionholder Consideration (as defined and calculated in Annex A), if any, by
the Closing Price for the Acquiror Common Stock.

                (b) Acquiror shall take all corporate action necessary to
reserve and make available for issuance a sufficient number of shares of
Acquiror Common Stock for delivery under Target Options assumed in accordance
with this Section 5.15. Promptly after the Effective Time, Acquiror shall file a
registration statement on Form S-8 (or any successor or other appropriate forms)
or amend an existing registration statement with respect to the shares of
Acquiror Common Stock subject to such Target Options and shall use its best
efforts to maintain the effectiveness of such registration statement or
registration statements for so long as such Target Options remain outstanding.

                (c) At the time specified and upon the achievement of the
milestones set forth on Annex A hereto, each holder of Target Options assumed in
the Merger that exercised such options prior to the Determination Date (as
defined on Annex A), shall receive (A) the Additional Exercised Option
Consideration (as defined on Annex A), divided by the aggregate number of shares
of Acquiror Common Stock issued upon exercise of options assumed in the Merger


                                       39
<PAGE>

prior to the Determination Date, multiplied by (B) the number of shares of
Acquiror Common Stock obtained by such holder upon the exercise of options
assumed in the Merger prior to the Determination Date.

        5.16    Escrow Agreement. On or before the Effective Time, Acquiror,
Target, the Escrow Agent and the Stockholders' Agent (as defined in Article VIII
hereto) will execute the Escrow Agreement contemplated by Article VIII in the
form attached hereto as Exhibit C.

        5.17    Listing of Additional Shares. Promptly after the date hereof,
Acquiror shall file with Nasdaq a Notification Form for Listing of Additional
Shares with respect to the Total Acquiror Shares and any additional shares of
Acquiror Common Stock required to be reserved for issuance upon exercise of
Target Options assumed by Acquiror and shall use reasonable best efforts to get
such shares accepted for quotation prior to the Effective Time.

breach of this Agreement;

                (d) by Target, if Acquiror shall breach any representation,
warranty, obligation or agreement hereunder and such breach shall not have been
cured within ten (10) days following receipt by Acquiror of written notice of
such breach, provided that the right to terminate this Agreement by Target under
this Section 7.1(d)(i) shall not be available to Target where Target is at that
time in material breach of this Agreement;

                (e) by Acquiror if (i) any permanent injunction or other order
of a court or other competent authority preventing the consummation of the
Merger shall have become final and nonappealable or (ii) if any required
approval of the stockholders of Target shall not have been obtained by reason of
the failure to obtain the required vote upon a vote held at a duly held meeting
of stockholders and any adjournment thereof;

                (f) by Target if any permanent injunction or other order of a
court or other competent authority preventing the consummation of the Merger

                (g) by Target if the Closing Price is less than $5.00.

        7.2     Effect of Termination. In the event of termination of this
Agreement as provided in Section 7.1, this Agreement shall forthwith become void
and there shall be no liability or obligation on the part of Acquiror or Target
or their respective officers, directors, stockholders or affiliates, except to
the extent that such termination results from or arises out of the breach by a
party hereto of any of its representations, warranties or covenants set forth in
this Agreement; provided that, the provisions of Section 5.5 (Confidentiality),
Section 7.3 (Expenses and Termination Fees) and this Section 7.2 shall remain in
full force and effect and survive any termination of this Agreement.

        7.3     Expenses and Termination Fees. Whether or not the Merger is

and the transactions contemplated hereby (including, without limitation, the

expenses of Target incurred in connection with this Agreement shall be
obligations of the Principal Stockholder. The Principal Stockholder shall


                                       49
<PAGE>

promptly pay the Surviving Corporation any expenses so incurred by Target, and
if such amounts remain unpaid for a period of thirty (30) days, such payment
shall constitute "Damages" recoverable under Article VIII hereof and the Escrow
Agreement.

        7.4     Amendment. The Boards of Directors of the parties hereto may
cause this Agreement to be amended at any time by execution of an instrument in
writing signed on behalf of each of the parties hereto and in accordance with

representations and warranties made to such party contained herein or in any

agreements or conditions for the benefit of such party contained herein. Any

                                  ARTICLE VIII

                           ESCROW AND INDEMNIFICATION

        8.1     Survival of Representations, Warranties and Covenants.
Notwithstanding any investigation conducted before or after the Closing Date,
and notwithstanding any actual or implied knowledge or notice of any facts or
circumstances which Acquiror or Target may have as a result of such
investigation or otherwise, Acquiror and Target will be entitled to rely upon
the other party's representations, warranties and covenants set forth in this
Agreement. The obligations of the parties with respect to their representations,
warranties, agreements and covenants will survive the Closing and continue in
full force and effect until the date 12 months following the Effective Time (the
"Termination Date"), at which time, subject to Section 8.5, the representations,
warranties and covenants of the parties set forth in this Agreement and any
liability of the parties with respect to those representations, warranties and
covenants will terminate; provided, however that the representations and
warranties (and the obligation of the parties with respect thereto) contained in
Section 2.14(a) and the covenants contained in Section 5.23(a) shall survive
until expiration of the applicable statute of limitations period with respect to
the Tax at issue. If a claim is made by either party prior to the expiration of
any representations, warranties, agreements or covenants, such claim shall
survive until such claim is finally resolved.

        8.2     Indemnity. From and after the Effective Time of the Merger, and
subject to the provisions of Section 8.1, Acquiror and the Surviving Corporation
(on or after the Closing Date) shall be indemnified and held harmless by the
Principal Stockholder against, and reimbursed for, any liability, damage, loss,
obligation, demand, judgment, fine, penalty, cost or expense, including
reasonable attorneys' fees and expenses, and the costs of investigation incurred
in defending against or settling such liability, damage, loss, cost or expense
or claim therefor and any amounts paid in settlement thereof, imposed on or
reasonably incurred by Acquiror or the Surviving Corporation as a result of (i)
any breach of any representation, warranty, agreement or covenant on the part of
Target or the Principal Stockholder under this Agreement or (ii) any of the
matters listed on Schedule 2.8 (collectively the "Damages"). "Damages" as used


                                       50
<PAGE>

herein is not limited to matters asserted by third parties, but includes Damages
incurred or sustained by Acquiror in the absence of claims by a third party. The
Principal Stockholder may satisfy any claim for which it is required to
indemnify the Acquiror and/or the Surviving Corporation pursuant to this Section
8.2 with, at the Principal Stockholder's sole discretion: (A) cash; (B) Acquiror
Common Stock; or (C) shares from the Escrow Fund. For purposes of compensating
the Acquiror for its damages pursuant to this Agreement, the Acquiror Common
Stock and/or shares from the Escrow Fund delivered or to be delivered to
Acquiror to satisfy the claim for indemnification hereunder shall be valued at
the weighted average closing price of the Acquiror Common Stock on the Nasdaq
National Market for the five (5) trading days immediately preceding the date of
payment of such claim.

        8.3     Escrow Fund. As security for the indemnity provided for in
Section 8.2 hereof, the Escrow Certificates shall be deposited by Acquiror in an
escrow account with The Chase Manhattan Bank (or other mutually acceptable
institution) as Escrow Agent (the "Escrow Agent"), as of the Effective Time,
such deposit to constitute an escrow fund (the "Escrow Fund") to be governed by
the terms set forth in this Agreement and the provisions of an Escrow Agreement
to be executed and delivered pursuant to Section 5.16. Upon compliance with the
terms hereof and subject to the provisions of this Article VIII, Acquiror and
the Surviving Corporation shall be entitled to obtain indemnity from the Escrow
Fund for Damages covered by the indemnity provided for in Section 8.2 of this
Agreement. Any and all distributions of Acquiror Common Stock issued in respect
thereof (including, without limitation, any shares issued pursuant to any stock
dividend, stock split, reverse stock split, combination or reclassification
thereof) shall be the property of the Principal Stockholder and shall be
deposited with the Escrow Agent. Cash dividends or other property distributed in
respect of Acquiror Common Stock shall be delivered to Principal Stockholder and
shall not be deposited with or retained by the Escrow Agent. The Principal
Stockholder shall be entitled to exercise any and all voting and other
consensual rights pertaining to the Acquiror Common Stock held in the Escrow
Fund (the "Escrow Shares") or any part thereof for any purpose not inconsistent
with the terms of this Agreement.

        8.4     Damage Threshold and Limitations. Notwithstanding the foregoing,
Acquiror may not receive any payment from the Escrow Fund unless and until an
Officer's Certificate (as defined in Section 8.6 below) identifying Damages the
aggregate amount of which exceeds $750,000 has been delivered to the Escrow
Agent as provided in Section 8.5 below and such amount is determined pursuant to
this Article VIII to be payable, in which case Acquiror shall receive payment
equal in value to the full amount of Damages. In determining the amount of any
Damage attributable to a breach, any materiality standard contained in a
representation, warranty or covenant of Acquiror shall be disregarded.
Notwithstanding anything to the contrary in this Agreement, Acquiror shall not
be entitled to indemnity with respect to any lost profits or other
consequential, incidental, indirect, special or punitive damages. In addition,
the maximum amount payable by the Principal Stockholder pursuant to the
indemnification provisions of this Article VIII shall not exceed the Initial
Total Consideration. Notwithstanding the foregoing, any Damages arising from a
breach, nonfulfillment of or noncompliance with any of the representations,
warranties, covenants, or agreements made by Principal Stockholder or Target in
this Agreement relating to Taxes incurred by reason of or in connection with
Target being part of an affiliated, consolidated, combined or unitary group for
Tax purposes (including any exhibit, letter, schedule, certificate or document
delivered pursuant hereto or other instrument referred to herein) or any facts


                                       51
<PAGE>

or circumstances constituting such an inaccuracy, breach, nonfulfillment or
noncompliance shall be unlimited.

        8.5     Escrow Period. The Escrow Period shall terminate at the
expiration of twelve (12) months after the Effective Time; provided, however,
that a portion of the Escrow Fund, which is necessary to satisfy any unsatisfied
claims specified in any Officer's Certificate theretofore delivered to the
Escrow Agent prior to termination of the Escrow Period with respect to facts and
circumstances existing prior to expiration of the Escrow Period, shall remain in
the Escrow Fund until such claims have been finally resolved, including without
limitation any claims relating to items set forth on Schedule 2.8 hereto.

        8.6     Claims upon Escrow Fund.

                (a) Upon receipt by the Escrow Agent on or before the
Termination Date of a certificate signed by the chief financial or chief
executive officer of Acquiror (an "Officer's Certificate"):

                      (i) stating that Acquiror or the Surviving Corporation has
incurred, paid or properly accrued (in accordance with GAAP) or knows of facts
giving rise to a reasonable probability that it will have to incur, pay or
accrue (in accordance with GAAP) Damages in an aggregate stated amount with
respect to which Acquiror or the Surviving Corporation is entitled to payment
from the Escrow Fund pursuant to this Agreement; and

                     (ii) specifying in reasonable detail the individual items
of Damages included in the amount so stated, the date each such item was
incurred, paid or properly accrued (in accordance with GAAP), or the basis for
such anticipated liability and the specific nature of the breach to which such
item is related,

the Escrow Agent shall, subject to the provisions of Section 8.7 of this
Agreement, deliver to Acquiror shares of Acquiror Common Stock, in an amount
necessary to indemnify Acquiror for the Damages claimed; provided, however, that
no shares of Acquiror Common Stock or cash shall be delivered to Acquiror, as a
result of a claim based upon an accrual of, or upon a reasonable probability of
having to incur, pay or accrue Damages until such time as the Acquiror has
actually incurred or paid Damages. All cash and shares of Acquiror Common Stock
subject to such claims shall remain in the Escrow Fund until Damages are
actually incurred or paid or the Acquiror determines in its reasonably good
faith judgment that no Damages will be required to be incurred or paid (in which
event such cash and shares shall be distributed to the Principal Stockholder in
accordance with Section 8.10 below).

                (b) For the purpose of compensating Acquiror for its Damages
pursuant to this Agreement, the Acquiror Common Stock in the Escrow Fund shall
be valued as set forth in Section 8.2.

        8.7     Objections to Claims. At the time of delivery of any Officer's
Certificate to the Escrow Agent, a duplicate copy of such Officer's Certificate
shall be delivered to the Principal Stockholder and for a period of forty-five
(45) days after such delivery to the Escrow Agent, the Escrow Agent shall make
no delivery of cash or Acquiror Common Stock or other property pursuant to
Section 8.6 hereof unless the Escrow Agent shall have received written


                                       52
<PAGE>

authorization from the Principal Stockholder to make such delivery. After the
expiration of such forty-five (45) day period, the Escrow Agent shall make
delivery of the Acquiror Common Stock or other property in the Escrow Fund in
accordance with Section 8.6 hereof, provided that no such payment or delivery
may be made if the Principal Stockholder shall object in a written statement to
the claim made in the Officer's Certificate, and such statement shall have been
delivered to the Escrow Agent and to Acquiror prior to the expiration of such
forty-five (45) day period.

        8.8     Resolution of Conflicts; Arbitration.

                (a) In case the Principal Stockholder shall object in writing to
any claim or claims by Acquiror made in any Officer's Certificate, the Principal
Stockholder and Acquiror shall attempt in good faith to agree upon the rights of
the respective parties with respect to each of such claims. If the Principal
Stockholder and Acquiror should so agree, a memorandum setting forth such
agreement shall be prepared and signed by both parties and shall be furnished to
the Escrow Agent. The Escrow Agent shall be entitled to rely on any such
memorandum and shall distribute the Acquiror Common Stock or other property from
the Escrow Fund in accordance with the terms thereof.

                (b) If no such agreement can be reached after good faith
negotiation for sixty (60) days, either Acquiror or the Principal Stockholder
may, by written notice to the other, demand arbitration of the matter unless the
amount of the Damage is at issue in pending litigation with a third party, in
which event arbitration shall not be commenced until such amount is ascertained
or both parties agree to arbitration; and in either such event the matter shall
be settled by arbitration conducted by three arbitrators. Within fifteen (15)
days after such written notice is given, Acquiror and the Principal Stockholder
shall each select one arbitrator, and the two arbitrators so selected shall
select a third arbitrator. The decision of the arbitrators as to the validity
and amount of any claim in such Officer's Certificate shall be binding and
conclusive upon the parties to this Agreement, and notwithstanding anything in
Section 8.6 hereof, the Escrow Agent shall be entitled to act in accordance with
such decision and make or withhold payments out of the Escrow Fund in accordance
therewith.

                (c) Judgment upon any award rendered by the arbitrators may be
entered in any court having jurisdiction. Any such arbitration shall be held in
New York, New York under the commercial rules then in effect of the American
Arbitration Association. For purposes of this Section 8.8, in any arbitration
hereunder in which any claim or the amount thereof stated in the Officer's
Certificate is at issue, Acquiror shall be deemed to be the Non-Prevailing Party
unless the arbitrators award Acquiror more than one-half (1/2) of the amount in
dispute, plus any amounts not in dispute; otherwise, the Principal Stockholder
shall be deemed to be the Non-Prevailing Party. The Non-Prevailing Party to an
arbitration shall pay its own expenses, the fees of each arbitrator, the
administrative fee of the American Arbitration Association, and the expenses,
including without limitation, attorneys' fees and costs, reasonably incurred by
the other party to the arbitration.

        8.9     Intentionally Omitted.

        8.10    Distribution Upon Termination of Escrow Period. Within five (5)
business days following the Termination Date, the Escrow Agent shall deliver to
the Principal Stockholder all of the shares in the Escrow Fund in excess of any
amount of such shares reasonably necessary to satisfy any unsatisfied or
disputed claims for Damages specified in any Officer's Certificate delivered to
the Escrow Agent on or before the Termination Date and any unsatisfied or
disputed claims by the Principal Stockholder. As soon as all such claims have
been resolved, the Escrow Agent shall deliver to the Principal Stockholder all
shares remaining in the Escrow Fund and not required to satisfy such claims.

        8.11    Intentionally Omitted.

        8.12    Third-Party Claims. In the event Acquiror becomes aware of a
third-party claim which Acquiror believes may result in a demand against the
Escrow Fund, Acquiror shall notify the Principal Stockholder of such claim, and
the Principal Stockholder shall be entitled, at his expense, to participate in
any defense of such claim. Acquiror shall have the right in its sole discretion
to settle any such claim; provided, however, that Acquiror may not effect the
settlement of any such claim without the consent of the Principal Stockholder,
which consent shall not be unreasonably withheld or delayed. In the event that
the Principal Stockholder has consented to any such settlement, the Principal
Stockholder shall have no power or authority to object under Section 8.6 or any
other provision of this Article VIII to the amount of any claim by Acquiror
against the Escrow Fund for indemnity with respect to such settlement.

        8.13    Indemnity by Acquiror.

                (a) From and after the Effective Time of the Merger, and subject
to the provisions of Section 8.1, the former stockholders of Target ("Target
Indemnitees") shall be indemnified and held harmless by Acquiror against, and
reimbursed for, any liability, damage, loss, obligation, demand, judgement,
fine, penalty, cost or expense, including reasonable attorneys' fees and
expenses, and the costs of investigation incurred in defending against or
settling such liability , damage, loss, cost or expense or claim therefor and
any amounts paid in settlement thereof, imposed on or reasonably incurred by
Target Indemnitees as a result of any breach of any representation, warranty,
agreement or covenant on the part of Acquiror under this Agreement (collectively
the "Target Damages"). "Target Damages" as used herein is not limited to matters
asserted by third parties, but includes Target Damages incurred or sustained by
Target Indemnitees in the absence of claims by a third party.

                (b) Notwithstanding the foregoing, Target Indemnitees may not
receive any payment from Acquiror unless and until an Officer's Certificate (as
defined in Section 8.6) identifying Target Damages the aggregate amount of which
exceeds $750,000 (the "Target Basket") has been delivered to the Chief Financial
Officer of the Acquiror as provided below and such amount is determined pursuant
to this Section 8.13 to be payable and then only for any and all such losses
without regard to the Target Basket, but only up to an amount equal to an
aggregate of the Initial Total Consideration.


                                       54
<PAGE>

                (c) The period in which the Target Indemnitees shall be entitled
to indemnification shall terminate at the expiration of twelve (12) months after
the Effective Time; provided, however, that any claims made prior to the
expiration of such period shall survive until such claims have been finally
resolved.

                (d) Upon receipt by Acquiror on or before the Termination Date
of a certificate signed by the Principal Stockholder:

                      (i) stating that the Target Indemnitees have incurred or
paid or knows of facts giving rise to a reasonable probability that it will have
to incur Target Damages in an aggregate stated amount with respect to which the
Target Indemnitees are entitled to indemnification pursuant to this Section
8.13; and

                     (ii) specifying in reasonable detail the individual items
of Target Damages included in the amount so stated, the date each such item was
incurred or paid, or the basis for such anticipated liability and the specific
nature of the breach to which such item is related,

Acquiror shall, subject to the provisions of subparagraph (e), deliver to the
Target Indemnitees, at its option, cash or Acquiror Common Stock, in an amount
necessary to indemnify the Target Indemnitees for the Target Damages claimed. If
the Acquiror shall choose to satisfy such claim by delivering Acquiror Common
Stock, such stock shall be distributed to the Target Indemnitees pro rata and
shall be valued in accordance with Section 8.2.

                (e) For a period of forty-five (45) days after delivery of the
certificate by the Principal Stockholder to Acquiror, Acquiror shall have the
right to object in a written statement to the claim made in the certificate
delivered by the Principal Stockholder. If no objection is made, Acquiror shall
issue Acquiror Common Stock to the Target Indemnitees as provided in
subparagraph (d) above. If Acquiror does so object, the Principal Stockholder
and Acquiror shall attempt in good faith to agree upon the rights of the
respective parties. If no such agreement can be reached in sixty (60) days, the
conflict shall be resolved in accordance with Section 8.8.

                (f) The right to stock in accordance with this Section 8.13
shall be the sole and exclusive remedy of the Target Indemnitess after the
Closing with respect to any breach of any representation, warranty, covenant or
agreement made by Acquiror or Merger Sub under this Agreement and no former
stockholder, optionholder, warrantholder, director, officer, employee or agent
of Acquiror shall have any personal liability to any Target Indemnitee after the
Closing in connection with the Merger.

executive officers or directors of such party and its subsidiaries reasonably
believed to have substantive knowledge of such matters. The phrase "made

the meaning or interpretation of this Agreement.

        9.3     Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

jurisdiction to be illegal, void or unenforceable, the remainder of 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 reasonably
to effect the intent of the parties hereto. The parties further agree to replace

enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

        9.6     Remedies Cumulative. Except as otherwise provided herein, any
and all remedies herein expressly conferred upon a party will be deemed
cumulative with and not exclusive of any other remedy conferred hereby, or by
law or equity upon such party, and the exercise by a party of any one remedy

         4.       Change of Control. In the event there is a Change of Control
(as defined below) of Acquiror or the Surviving Company after the Closing (the
"Applicable Entity"), Acquiror shall use its best efforts to cause the other
party to such Change of Control to continue the operations of Target and the
Electronic Services Business following the Change of Control in good faith and
in a manner consistent with the business practices of Target prior to Closing.
For the purposes hereof, "Change of Control" of the Applicable Entity means the
happening of any of the following: (i) the sale of all or substantially all of
the Applicable Entity's assets; (ii) the merger or consolidation of the
Applicable Entity into or with another person or entity; (iii) when any "person"
as defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act") and as used in Sections 13(d) and 14(d) thereof including a
"group" as defined in Section 13(d) of the Exchange Act but excluding the
Applicable Entity and any subsidiary and any existing stockholder to the extent
of their holdings as of the date of the Agreement, directly or indirectly,
becomes the "beneficial owner" (as defined in Rule 13(d)-3 under the Exchange
Act, as amended from time to time), of securities of the Applicable Entity
representing 50% or more of the combined voting power of the Applicable Entity's
then outstanding securities; or (iv) with respect to Acquiror, when, during any
period of three (3) consecutive months during calendar year 2001, the
individuals who, at the beginning of such period, constitute the Board of
Directors of Acquiror (the "Incumbent Directors") cease for any reason other
than death to constitute at least a majority thereof; provided, however, that a
director who was not a director at the beginning of such three-month period
shall be deemed to have satisfied such three-month requirement (and be an
Incumbent Director) if such director was elected by, or on the recommendation of
or with the approval of, at least two-thirds of the directors who then qualified
as Incumbent Directors either actually (because they were directors at the
beginning of such three-month period) or by prior operation of this paragraph 3.
Upon a Change of Control, Acquiror shall notify Principal Stockholder as soon as
is commercially possible that such a Change of Control has occurred and the
circumstances relating thereto.

         5.       Reporting Requirements.
                  ----------------------

                  (a)      Within forty five (45) days following the close of
each calendar quarter during 2001, Acquiror shall deliver to the Principal
Stockholder a statement in which it shall accurately account for all Revenues of
the Electronic Services Business described in this Annex A for such quarter then
ended (the "Quarterly Revenues Notice"), and within one hundred twenty days
(120) days following December 31, 2001, Acquiror shall deliver to the Principal
Stockholder audited financial statements which accurately account for all
Revenues of the Electronic Services Business described in this Annex A for the
year then ended (the "Final Revenues Notice"), in both cases showing in
reasonable detail the computation thereof, to be accompanied by a certification
of Acquiror's chief financial officer that, in the opinion of such officer after
examining the books and records of Acquiror and Target, that the statement of
Acquiror presents fairly in all material respects the Revenues required to be
recognized in accordance with this Annex A and that such computation was
complete and accurate.

                                       2
<PAGE>

                  (b)      Upon receipt of the Quarterly Revenues Notice and the
Final Revenues Notice, Principal Stockholder may, at its own expense, audit the
books and records of Acquiror and Target in which the information concerning
Revenues is recorded, and the records supporting the entries in the books of
Acquiror and Target, for that quarter or year or any prior quarterly period for
which Principal Stockholder had not previously audited such books and records;
provided, however, that such audits be performed no more often than quarterly
during normal business hours and at the place where those books and records are
kept. Principal Stockholder shall notify Acquiror of such audit results
specifying in reasonable detail all disputed items and the basis therefor (the
"Audit Notice"). After receipt of the Audit Notice, Acquiror shall have thirty
(30) days to review the Audit Notice. Unless the Acquiror delivers a written
objection to Principal Stockholder on or prior to the 30th day after receipt of
the Audit Notice, the Acquiror shall be deemed to have accepted and agreed to
results set forth in the Audit Notice.

         6.       Dispute Resolution. If the Acquiror notifies Principal
Stockholder of its objection to the Audit Notice, the Acquiror and the Principal
Stockholder shall, within ten (10) days following such notice (the "Resolution
Period"), attempt to resolve their differences, and any resolution by them as to
any disputed amounts shall be final, binding and conclusive. If Principal
Stockholder and Acquiror are unable to agree on the amount of Revenues that
should be recognized for the applicable quarterly period, then, promptly after
the Resolution Period, the Principal Stockholder and Acquiror shall select a
nationally recognized independent accounting firm other than the Principal
Stockholder's or Acquiror's current or former independent accounting firms (the
"Neutral Auditor") to resolve the amount under dispute (the "Disputed Amount"),
which firm shall conclusively resolve the Disputed Amount within ten (10) days
or as soon as possible thereafter. If Principal Stockholder and Acquiror are
unable to agree on the Neutral Auditor, then the Principal Stockholder and
Acquiror shall each have the right to request the American Arbitration
Association to appoint the Neutral Auditor (other than the Principal
Stockholder's or Acquiror's regular independent accounting firms). The findings
of the Neutral Auditor shall be final and binding upon the parties.

         7.       Payment of Additional Cash, Adjustment to Options. The
Additional Cash to be paid hereunder to each former stockholder of Target and to
each optionholder to the extent that such optionholder exercises options prior
to the Determination Date shall be so paid, and the adjustment of the number and
exercise price of Acquiror options pursuant to Section 5.15 shall be so made on
the Determination Date. The Determination Date shall be the earlier of (a) 150
days after December 31, 2001 and (b) the date the Principal Stockholder notifies
Acquiror in writing of its agreement with the Final Revenues Notice; provided,
that if the Principal Stockholder chooses to audit the Final Revenues Notice as
provided in 5(c), such cash shall not be paid and the adjustment to the Acquiror
options shall not be made until the resolution of such audit as provided above.
