<PAGE>   5

Escrow Fund on such holder's behalf pursuant to Section 8 and (B) cash in the
amount of the Cash Consideration to which such holder is entitled as provided in
Section 1.6(a), less the amount of cash paid to accountants, legal counsel or
other consultants or advisors in connection with Accrued Fees, and the
certificate(s) for Target Capital Stock so surrendered shall forthwith be
cancelled. Until so surrendered, each certificate of Target Capital Stock will

evidence the right to receive the Merger Consideration.

                        (d) 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.

                        (f) 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 will be paid to the holder of any
unsurrendered Certificate with respect to the shares of Acquiror Common Stock

surrender such Certificate. Subject to applicable law, following surrender of
any such Certificate, there shall be paid to the record holder of the
certificates representing whole shares of Acquiror Common Stock issued in
exchange therefor, without interest, at the time of such surrender, the amount

Effective Time payable (but for the provisions of this Section 1.7(f)) with
respect to such shares of Acquiror Common Stock.

                        (g) 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 will be
a condition of such issuance that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the person
requesting such exchange will have paid to 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.

                1.8 NO FURTHER OWNERSHIP RIGHTS IN TARGET CAPITAL STOCK. All
shares of Acquiror Common Stock issued upon the surrender for exchange of shares
of Target Capital Stock in accordance with the terms hereof (including any cash
paid in lieu of fractional shares) shall be deemed to have been issued, and all
cash in the amount of the Cash Consideration shall be deemed to have been paid,
in full satisfaction of all rights pertaining to such shares of Target Capital
Stock, and there shall be no further registration of transfers on the records of
the Surviving Corporation of shares of Target Capital Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be cancelled and exchanged as provided in this Section 1.

                1.9 TAX AND ACCOUNTING CONSEQUENCES. It is intended by the
parties hereto that the Merger shall constitute a reorganization within the
meaning of Section 368 of the Code.

                1.10 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 and Merger Sub, the officers and directors of
Target and Merger Sub are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action, so long as such action is not inconsistent with this Agreement.

                1.11 WITHHOLDING. Each of the Exchange Agent, Acquiror, and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
holder or former holder of Target Common Stock such amounts as may be required
to be deducted or withheld therefrom under the Code or any provision of state,
local or foreign tax law or under any other applicable legal requirement. To the
extent such amounts are so deducted or withheld, such amounts shall be treated
for all purposes under this Agreement as having been paid to the person to whom
such amounts would otherwise have been paid.

                1.12 LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
exchange for such lost, stolen or destroyed Certificates, upon the making of an
affidavit of that fact by the holder thereof, such Merger Consideration as may
be required pursuant to Section 1.6; provided, however, that Acquiror may, in
its discretion and as a condition precedent to such exchange, require the owner
of such lost, stolen or destroyed Certificates to deliver a bond in such sum as
Acquiror 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.

                                   SECTION TWO

with respect to any entity or group of entities means any event, change or
effect that, when taken individually or together with all other adverse changes
and effects, is or is reasonably likely to be materially adverse to the
condition (financial or otherwise), properties, assets, liabilities, business as
currently conducted and as proposed to be conducted, operations, results of
operations or prospects of such entity and its subsidiaries, taken as a whole,
or to prevent or materially delay consummation of the Merger or otherwise to
prevent such entity and its subsidiaries from performing their obligations under
this Agreement.

                In this Agreement, any reference to a party's "knowledge" means
such party's actual knowledge after due and diligent inquiry of officers,
directors and other employees of such party reasonably believed to have
knowledge of the matter in questions.

                Except as disclosed in a document dated as of the date of this
Agreement and delivered by Target and Target Stockholder to Acquiror prior to
the execution and delivery of this Agreement and referring to the
representations and warranties in this Agreement (the

                                       5

"Target Disclosure Schedule"), Target and Target Stockholder represent and
warrant to Acquiror and Merger Sub as follows:

                2.1 ORGANIZATION; SUBSIDIARIES. Target is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization. Target has the requisite corporate power and
authority and all necessary government approvals to own, lease and operate its
properties and to carry on its business as now being conducted and as proposed
to be conducted, except where the failure to have such power, authority and
governmental approvals would not, individually or in the aggregate, have a
Material Adverse Effect on Target. Target is duly qualified or licensed as a
foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its business makes such qualification or licensing
necessary, except for such failures to be so qualified or licensed and in good
standing that would not, individually or in the aggregate, have a Material
Adverse Effect on Target. Section 2.1 of Target Disclosure Schedule sets forth
each jurisdiction where Target is qualified to do business. 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 Target,
or otherwise obligating Target to issue, transfer, sell, purchase, redeem or
otherwise acquire any such securities. Target has never had, nor does it
currently have, any subsidiaries, nor has it ever owned, nor does it currently
own, directly or indirectly, any equity or similar interest in, or any interest
convertible into or exchangeable or exercisable for, any equity or similar
interest in, any corporation, partnership, limited liability company, joint
venture or other business association or entity

                2.2 ARTICLES OF INCORPORATION AND BYLAWS. Target has delivered
to Acquiror a true and correct copy of the Articles of Incorporation and Bylaws
or other charter documents, as applicable, of Target, 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.

                2.3 CAPITAL STRUCTURE. The authorized capital stock of Target
consists of 10,000 shares of voting Common Stock and no shares of Preferred
Stock, of which there were issued and outstanding as of the date hereof 1,000
shares of voting Common Stock. There are no other outstanding shares of capital
stock or voting securities or nonvoting securities and no outstanding
commitments to issue any shares of capital stock or voting or nonvoting
securities after the date hereof. There is not now, and since the inception of
Target there has not been, any stock option plan or other securities based
employee incentive program for Target employees, officers, directors or
consultants. All outstanding shares of Target Capital 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 or rights of first
refusal created by statute, the Articles of Incorporation or Bylaws of Target or
any agreement to which Target is a party or by which it is bound. All
outstanding shares of Target Common Stock were issued in compliance with all
applicable federal and state securities laws. Except (i) for the rights created
pursuant to this Agreement, (ii) as set forth in this Section 2.3, there are no
options, warrants, calls, rights, commitments, agreements or arrangements of any
character to which Target is a party or by which Target is bound relating to the
issued or unissued capital stock of Target or obligating Target to issue,
deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold,

                                       6
<PAGE>   8

repurchased or redeemed, any shares of capital stock of Target 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. There are no contracts, commitments or agreements relating to
voting, purchase or sale of Target's capital stock (i) between or among Target
and any of its stockholders and (ii) to the best of Target's knowledge, between
or among any of Target's stockholders, except for the stockholders delivering
Irrevocable Proxies (as defined below).

                2.4 AUTHORITY. Target has all requisite corporate power and
authority to enter into this Agreement and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby 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). Target's Board of Directors has unanimously approved the Merger and this
Agreement. This Agreement has been duly executed and delivered by Target and
assuming due authorization, execution and delivery by Acquiror and Merger Sub,
constitutes the valid and binding obligation of Target enforceable against
Target in accordance with its terms. Target Stockholder has the requisite
capacity to enter into this Agreement and to consummate the transaction
contemplated hereby. This Agreement has been duly executed and delivered by
Target Stockholder and constitutes a valid and binding obligation enforceable
against him in accordance with its terms.

                2.5 NO CONFLICTS; REQUIRED FILINGS AND CONSENTS.

                        (a) The execution and delivery of this Agreement by
Target does not, and the consummation of the transactions contemplated hereby
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 Articles of Incorporation or Bylaws of
Target, as amended, or (ii) any material mortgage, indenture, lease, contract or
other agreement or instrument, permit, concession, franchise, license, judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to Target
or any of its properties or assets.

                        (b) 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, or the Target Stockholder in
connection with the execution and delivery of this Agreement or the consummation
of the transactions contemplated hereby, 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 may be required under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), the Securities Act of
1933, as amended (the "Securities Act"), applicable state securities laws and
the securities laws of any foreign country; and (iii) such other consents,
authorizations, filings, approvals and registrations which, if not obtained or
made, would not have a Material Adverse Effect on Target and would not prevent,
or materially alter or delay any of the transactions contemplated by this
Agreement.

could reasonably be expected to have a Material Adverse Effect on Target. There
is no judgment, decree or order against Target or, to the best knowledge of
Target, any of its directors or officers (in their capacities as such), that
could prevent, enjoin, or materially alter or delay any of the transactions

                2.10 RESTRICTIONS ON BUSINESS ACTIVITIES. Except as set forth on
Schedule 2.10, there is no agreement, judgment, injunction, order or decree
binding upon Target which has or could reasonably be expected to have the effect

Target. Except as set forth on Schedule 2.10, Target has not entered into any

                        (a) Target is in possession of all franchises, grants,
authorizations, licenses, permits, easements, variances, exceptions, consents,
certificates, approvals and orders necessary for Target, to own, lease and
operate its properties or to carry on its business as it is now being conducted
(the "Target Authorizations") and no suspension or cancellation of any Target
Authorization is pending or, to the best of Target's knowledge, threatened,
except where the failure to have, or the suspension or cancellation of, any
Target Authorization would not have a Material Adverse Effect on Target. Target
is not in conflict with, or in default or violation of, (i) any laws applicable
to Target or by which any property or asset of Target is bound or affected, (ii)
any Target Authorization, or (iii) any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Target is a party or by which Target or any property or

                                       10
<PAGE>   12

such conflict, default or violation that would not, individually or in the
aggregate, have a Material Adverse Effect on Target.

                        (b) Except as would not have a Material Adverse Effect
on Target, there have been no written notices, citations or decisions by any
governmental or regulatory body that any product produced, manufactured,
marketed or distributed at any time by Target (the "Products") is defective or
fails to meet any applicable standards promulgated by any such governmental or
regulatory body. To the best knowledge of Target, Target has complied in all
material respects with the laws, regulations, policies, procedures and
specifications with respect to the design, manufacture, labeling, testing and
inspection of the Products. Except as disclosed in Section 2.11(b) of the Target
Disclosure Schedule, there have been no recalls, field notifications or seizures
ordered or, to Target's knowledge, threatened by any such governmental or
regulatory body with respect to any of the Products.

                        (c) Target has obtained, in all countries where Target
is marketing or has marketed its Products, all applicable licenses,
registrations, approvals, clearances and authorizations required by local, state
or federal agencies in such countries regulating the safety, effectiveness and
market clearance of the Products currently or previously marketed by Target in
such countries, except for any such failures as would not, individually or in
the aggregate, have a Material Adverse Effect on Target. Target has identified
and made available for examination by Acquiror all information relating to
regulation of its Products, including licenses, registrations, approvals and
permits. Target does not keep regulatory information or documents in any
location outside of the United States.

                2.12 TITLE TO PROPERTY.

                        (a) Target has good and marketable title to all of its
properties, interests in properties and assets, real and personal, reflected in
the Target Balance Sheet or acquired after the Target Balance Sheet Date (except
properties, interests in properties and assets sold or otherwise disposed of
since the Target Balance Sheet Date in the ordinary course of business), or with
respect to leased properties and assets, valid leasehold interests in, 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 which is reflected on
the Target Balance Sheet. The plants, property and equipment of Target that are
used in the operations of its business are in good operating condition and
repair. All properties used in the operations of Target are reflected in the
Target Balance Sheet to the extent United States generally accepted accounting
principles require the same to be reflected. Section 2.12(a) of the Target
Disclosure Schedule sets forth a true, correct and complete list of all real
property owned or leased by Target, the name of the lessor, the date of the
lease and each amendment thereto and the aggregate annual rental and other fees
payable under such lease. Such leases are in good standing, are valid and
effective in accordance with their respective terms, and there is not under any
such leases any existing default or event of default (or event which with notice
or lapse of time, or both, would constitute a default).

                                       11
<PAGE>   13

                        (b) Section 2.12(b) of the Target Disclosure Schedule
also sets forth a true, correct and complete list of all equipment (the
"Equipment") owned or leased by Target, and such Equipment is, taken as a whole,
(i) adequate for the conduct of Target's business, consistent with its past
practice, and (ii) in good operating condition (except for ordinary wear and
tear).

                2.13 INTELLECTUAL PROPERTY.

                        (a) Target owns, or is licensed or otherwise possesses
legally enforceable rights to use all patents, patent rights, trademarks,
trademark rights, trade names, trade name rights, service marks, copyrights, and
any applications for any of the foregoing, maskworks, net lists, schematics,
industrial models, inventions, technology, know-how, trade secrets, inventory,
ideas, algorithms, processes, computer software programs or applications (in
both source code and object code form), and tangible or intangible proprietary
information or material, including, without limitation, the eSchedule Software
(as defined below in Schedule 2.29 hereof) in development and the Other Keren
Software (as defined below in Schedule 2.29 hereof), (collectively, the
"Intellectual Property") that are used or proposed to be used in the business of
Target as currently conducted or as proposed to be conducted by Target, except
to the extent that the failure to have such rights have not had and could not
reasonably be expected to have a Material Adverse Effect on Target.

                        (b) Section 2.13 of the Target Disclosure Schedule lists
(i) all patents and patent applications and all registered and unregistered
trademarks, trade names and service marks, registered and unregistered
copyrights, and maskworks, included in the Intellectual Property, including the
jurisdictions in which each such Intellectual Property right has been issued or
registered or in which any application for such issuance and registration has
been filed, (ii) all licenses, sublicenses and other agreements as to which
Target is a party and pursuant to which any person is authorized to use any
Intellectual Property, and (iii) all licenses, sublicenses and other agreements
as to which Target is a party and pursuant to which Target is authorized to use
any third party patents, trademarks or copyrights, including software ("Third
Party Intellectual Property Rights") which are incorporated in, are, or form a
part of any Target product that is material to its business. Target is not in
violation of any license, sublicense or agreement described in Section 2.13 of
the Target Disclosure Schedule. The execution and delivery of this Agreement by
Target and the consummation of the transactions contemplated hereby, will
neither cause Target to be in violation or default under any such license,
sublicense or agreement, nor entitle any other party to any such license,
sublicense or agreement to terminate or modify such license, sublicense or
agreement. Except as set forth in Section 2.13 of the Target Disclosure
Schedule, Target is the sole and exclusive owner or licensee of, with all right,
title and interest in and to (free and clear of any liens), the Intellectual
Property, and has sole and exclusive rights (and is not contractually obligated
to pay any compensation to any third party in respect thereof) to the use
thereof or the material covered thereby in connection with the services or
products in respect of which Intellectual Property is being used.

                        (c) There is no material unauthorized use, disclosure,
infringement or misappropriation of any Intellectual Property rights of Target,
any trade secret material to Target or any Intellectual Property right of any
third party to the extent licensed by or through Target, by any third party,
including any employee or former employee of Target. Target has not

                                       12
<PAGE>   14

entered into any agreement to indemnify any other person against any charge of
infringement of any Intellectual Property, other than indemnification provisions
contained in purchase orders arising in the ordinary course of business.

                        (d) Target is not nor will be as a result of the
execution and delivery of this Agreement or the performance of its obligations
under this Agreement, in breach of any license, sublicense or other agreement
relating to the Intellectual Property or Third Party Intellectual Property
Rights, the breach of which would have a Material Adverse Effect on Target.

                        (e) All patents, registered trademarks, service marks
and copyrights held by Target are valid and existing and there is no assertion
or claim (or basis therefor) challenging the validity of any Intellectual
Property of Target. Target has not been sued in any suit, action or proceeding
which involves a claim of infringement of any patents, trademarks, service
marks, copyrights or violation of any trade secret or other proprietary right of
any third party. Neither the conduct of the business of Target as currently
conducted or contemplated nor the manufacture, sale, licensing or use of any of
the products of Target as now manufactured, sold or licensed or used, nor the
use in any way of the Intellectual Property in the manufacture, use, sale or
licensing by Target of any products currently proposed, infringes on or will
infringe or conflict with, in any way, any license, trademark, trademark right,
trade name, trade name right, industrial model, invention, service mark or
copyright (except for patents and patent rights, which shall be to the best
knowledge of the Target) of any third party that, individually or in the
aggregate, is reasonably likely to have a Material Adverse Effect on Target. All
registered trademarks, service marks and copyrights held by Target are valid and
existing. To Target's knowledge, no third party is challenging the ownership by
Target, or the validity or effectiveness of, any of the Intellectual Property.
Target has not brought any action, suit or proceeding for infringement of
Intellectual Property or breach of any license or agreement involving
Intellectual Property against any third party. There are no pending, or to the
best of Target's knowledge, threatened interference, re-examinations,
oppositions or nullities involving any patents, patent rights or applications
therefor of Target, except such as may have been commenced by Target. There is
no breach or violation of or threatened or actual loss of rights under any
license agreement to which Target is a party.

                        (f) Target owns all Intellectual Property developed by
consultants, if any, and employees, if any, who contributed to the creation or
development of the Intellectual Property by operation of law.

                        (g) All Intellectual Property not otherwise protected by
patents, patent applications or copyright ("Confidential Information") has had
its confidentiality protected and preserved.

<PAGE>   16

                        (a) For purposes of this Section 2.15 and other
provisions of this Agreement relating to Taxes, the following definitions shall
apply:

                                (i) The term "Taxes" shall mean all taxes,
however denominated, including any interest, penalties or other additions to tax
that may become payable in respect thereof, (A) imposed by any federal,
territorial, state, local or foreign government or any agency or political
subdivision of any such government, which taxes shall include, without limiting
the generality of the foregoing, all income or profits taxes (including but not
limited to, federal, state and foreign income taxes), payroll and employee
withholding taxes, unemployment insurance contributions, social security taxes,
sales and use taxes, ad valorem taxes, excise taxes, franchise taxes, gross
receipts taxes, withholding taxes, business license taxes, occupation taxes,
real and personal property taxes, stamp taxes, environmental taxes, transfer
taxes, workers' compensation, Pension Benefit Guaranty Corporation premiums and
other governmental charges, and other obligations of the same or of a similar
nature to any of the foregoing, which are required to be paid, withheld or
collected, (B) any liability for the payment of amounts referred to in (A) as a
result of being a member of any affiliated, consolidated, combined or unitary
group, or (C) any liability for amounts referred to in (A) or (B) as a result of
any obligations to indemnify another person.

                                (ii) The term "Returns" shall mean all reports,
estimates, declarations of estimated tax, information statements and returns
required to be filed in connection with any Taxes, including information returns
with respect to backup withholding and other payments to third parties.

                        (b) All Returns required to be filed by or on behalf of
Target have been duly filed on a timely basis and such Returns are true,
complete and correct. All Taxes shown to be payable on such Returns or on
subsequent assessments with respect thereto, and all payments of estimated Taxes
required to be made by or on behalf of Target under Section 6655 of the Code or
comparable provisions of state, local or foreign law, have been paid in full on
a timely basis, and no other Taxes are payable by Target with respect to items
or periods covered by such Returns (whether or not shown on or reportable on
such Returns). Target has withheld and paid over all Taxes required to have been
withheld and paid over, and complied with all information reporting and backup
withholding in connection with amounts paid or owing to any employee, creditor,
independent contractor, or other third party. There are no liens on any of the
assets of Target with respect to Taxes, other than liens for Taxes not yet due
and payable or for Taxes that Target is contesting in good faith through
appropriate proceedings. Target has not been at any time a member of an
affiliated group of corporations filing consolidated, combined or unitary income
or franchise tax returns for a period for which the statute of limitations for
any Tax potentially applicable as a result of such membership has not expired.

                        (c) The amount of Target's liabilities for unpaid Taxes
for all periods through the date of the Financial Statements do not, in the
aggregate, exceed the amount of the current liability accruals for Taxes
reflected on the Financial Statements, and the Financial Statements properly
accrue in accordance with generally accepted accounting principles ("GAAP") all
liabilities for Taxes of Target payable after the date of the Financial
Statements attributable to transactions and events occurring prior to such date.
No liability for Taxes of

                                       15
<PAGE>   17

Target has been incurred (or prior to Closing will be incurred) since such date

                        (d) Acquiror has been furnished by Target true and
complete copies of (i) relevant portions of income tax audit reports, statements
of deficiencies, closing or other agreements received by or on behalf of Target
relating to Taxes, and (ii) all federal, state and foreign income or franchise
tax returns and state sales and use tax Returns for or including Target for all
periods since later of Target's inception, or five full years preceding date of
agreement.

                        (e) No audit of the Returns of or including Target by a
government or taxing authority is in process, threatened or, to Target's
knowledge, pending (either in writing or orally, formally or informally). No
deficiencies exist or have been asserted (either in writing or orally, formally
or informally) or are expected to be asserted with respect to Taxes of Target,
and Target has not received notice (either in writing or orally, formally or
informally) nor does it expect to receive notice that it has not filed a Return
or paid Taxes required to be filed or paid. Target is not a party to any action
or proceeding for assessment or collection of Taxes, nor has such event been
asserted or threatened (either in writing or orally, formally or informally)
against Target or any of its assets. No waiver or extension of any statute of
limitations is in effect with respect to Taxes or Returns of Target. Target has
disclosed on its federal and state income and franchise tax returns all
positions taken therein that could give rise to a substantial understatement
penalty within the meaning of Code Section 6662 or comparable provisions of
applicable state tax laws.

                        (f) Target is not (nor have it ever been) party to any
tax sharing agreement. Since the date of its inception, Target has not been a
distributing corporation or a controlled corporation in a transaction described
in Section 355(a) of the Code.

                        (g) Target is not, nor has it been, a United States real
property holding corporation within the meaning of Section 897(c)(2) of the Code
during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code.
Target is not a "consenting corporation" under Section 341(f) of the Code.
Target has not entered into any compensatory agreements with respect to the
performance of services which payment thereunder would result in a nondeductible
expense to Target pursuant to Section 280G of the Code or an excise tax to the
recipient of such payment pursuant to Section 4999 of the Code. Target has not
agreed to, nor is it required to make, other than by reason of the Merger, any
adjustment under Code Section 481(a) by reason of, a change in accounting
method, and Target will not otherwise have any income reportable for a period
ending after the Closing Date attributable to a transaction or other event
(e.g., an installment sale) occurring prior to the Closing Date with respect to
which Target received the economic benefit prior to the Closing Date. Target is
not, nor has it been, a "reporting corporation" subject to the information
reporting and record maintenance requirements of Section 6038A and the
regulations thereunder.

                        (h) The Target Disclosure Schedule contains accurate and
complete information regarding Target's net operating losses for federal and
each state tax purposes. Target has no net operating losses and credit
carryovers or other tax attributes currently subject to limitation under

                2.16 EMPLOYEE BENEFIT PLANS.

                        (a) Schedule 2.16 lists, with respect to Target, and any
trade or business (whether or not incorporated) which is treated as a single
employer with Target (an "ERISA Affiliate") within the meaning of Section
414(b), (c), (m) or (o) of the Code, (i) all employee benefit plans (as defined
in Section 3(3) of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA")), (ii) each loan to a non-officer employee, loans to officers
and directors and any stock option, stock purchase, phantom stock, stock
appreciation right, supplemental retirement, severance, sabbatical, medical,
dental, vision care, disability, employee relocation, cafeteria benefit (Code
Section 125) or dependent care (Code Section 129), life insurance or accident
insurance plans, programs or arrangements, (iii) all contracts and agreements
relating to employment and all severance agreements, with any of the directors,
officers or employees of Target (other than, in each case, any such contract or
agreement that is terminable by Target at will or without penalty or other
adverse consequence), (iv) all bonus, pension, profit sharing, savings, deferred
compensation or incentive plans, programs or arrangements, (v) other fringe or
employee benefit plans, programs or arrangements that apply to senior management
of Target and that do not generally apply to all employees, and (vi) any current
or former employment or executive compensation or severance agreements, written
or otherwise, as to which unsatisfied obligations of Target remain for the
benefit of, or relating to, any present or former employee, consultant or
director of Target (together, the "Target Employee Plans").

                        (b) Target has furnished to Acquiror a copy of each of
the Target Employee Plans and related plan documents (including trust documents,
insurance policies or contracts, employee booklets, summary plan descriptions
and other authorizing documents, and, to the extent still in its possession, any
material employee communications relating thereto) and has, with respect to each
Target Employee Plan which is subject to ERISA reporting requirements, provided
copies of the Form 5500 reports filed for the last three plan years. Any Target
Employee Plan intended to be qualified under Section 401(a) of the Code has
either obtained from the Internal Revenue Service a favorable determination
letter as to its qualified status under the Code, including all amendments to
the Code effected by the Tax Reform Act of 1986 and subsequent legislation, or
has applied to the Internal Revenue Service for such a determination letter
prior to the expiration of the requisite period under applicable Treasury
Regulations or Internal Revenue Service pronouncements in which to apply for
such determination letter and to make any amendments necessary to obtain a
favorable determination. Target has also furnished Acquiror with the most recent

its subsidiaries' business ("Acquiror Authorizations"), and all of such Acquiror
Authorizations are in full force and effect, except where the failure to obtain
or have any of such Acquiror Authorizations could not reasonably be expected to

                THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE
                SECURITIES OR "BLUE-SKY" LAWS. THESE SECURITIES MAY NOT BE SOLD,

                TRANSFER OF THESE SECURITIES IS SUBJECT TO THE CONDITIONS
                SPECIFIED IN SECTION 5 OF THE AGREEMENT AND PLAN OF MERGER AMONG
                PRINTCAFE, INC., AHP SYSTEMS, INC., PRINTCAFE SYSTEMS, INC. AND

                        (c) prior to any Transfer of any Acquiror Securities,

Acquiror of such Stockholder's intention to effect such Transfer and to comply
in all other respects with the provisions of this Agreement. Each such notice
shall describe the manner and circumstances of the proposed Transfer and, if
requested by the Acquiror, shall be accompanied by the written opinion,
addressed to the Acquiror, of counsel for the holder of such Acquiror
Securities, stating that in the opinion of such counsel (which opinion and
counsel shall be reasonably satisfactory to the Acquiror) such proposed transfer
does not involve a transaction requiring registration or qualification of such
Securities under the Act or the securities or "blue-sky" laws of any relevant
state of the United States. The holder thereof shall thereupon be entitled to
Transfer such Acquiror Securities in accordance with the terms of the notice
delivered by it to the Acquiror. Each certificate or other instrument evidencing
the securities issued upon the Transfer of any such Securities (and each
certificate or other instrument evidencing any untransferred balance of such
Acquiror Securities) shall bear the legend set forth in Section 5(b) hereof
unless (x) in such opinion of counsel of Acquiror registration of any future
Transfer is not required by the applicable provisions of the Securities Act or
(y) Acquiror shall have waived the requirement of such legends. The Stockholder
shall not Transfer any Securities until such opinion of counsel has been given
(unless waived by the Acquiror or unless such opinion is not required in
accordance with the provisions of Section 5).

                        (d) Notwithstanding the foregoing provisions of Section
5(a) through (c) hereof, the restrictions imposed by Section 5(c) upon the
transferability of Acquiror Securities shall cease and terminate when (i) any
such shares are sold or otherwise disposed of pursuant to an effective

securities so transferred are not required to bear the legend set forth in
Section 5(b) or (iii) the holder of such Acquiror Securities has met the
requirements for Transfer of such Acquiror Securities pursuant to subparagraph
(k) of Rule 144. Whenever the restrictions imposed by this Agreement shall
terminate, as herein provided, the holder of Acquiror Securities as to which
such restrictions have terminated shall be entitled to receive from the
Acquiror, without expense, a new certificate not bearing the restrictive legend
set forth in Section 5(b) hereof and not containing any other reference to the
restrictions imposed by Section 5(b) hereof; provided that the restrictions set

or affiliate of Acquiror, shall assume the Personal Guarantees of Target
Stockholder and Acquiror shall indemnify Target Stockholder and hold Target

Persons incurs by reason of or in connection with any claim, demand, action or
cause of action alleging misrepresentation, breach of, or default in connection
with, any of the representations, warranties, covenants or agreements of Target
contained in this Agreement, including any exhibits or schedules attached
hereto, and the Certificate of Merger, which becomes known to Acquiror during
the Escrow Period or, with respect to the representations and warranties
contained in Sections 2.14, 2.15 and/or 2.16 hereof, the Special Indemnity
Termination Date. Damages in each case shall be net of the amount of any
insurance proceeds and indemnity and contribution actually recovered by Acquiror
or the Surviving Corporation.

                        (b) LIMITATIONS. The maximum liability of Target
Stockholder for any breach of a representation, warranty or covenant of Target
or Target Stockholder contained in this Agreement, including all Exhibits and
Schedules attached hereto, shall be limited to the amount of the Escrow Fund;
provided, however, that nothing herein, including the termination of the Escrow
Fund on the Escrow Termination Date shall limit the liability: (i) of Target for
any breach of representation, warranty or covenant if the Merger does not close,
(ii) of Target or Target Stockholder in connection with any breach of any of the
representations and warranties contained in Sections 2.1, 2.3, 2.4, 2.14, 2.15
and 2.16, (iv) of any officer, director or Target Stockholder in connection with
a Fraud Claim and (v) of Target Stockholder in connection with the failure to
pay any Accrued Fees.

                8.4 DAMAGES THRESHOLD. Notwithstanding the foregoing, Acquiror
may not receive any amount from the Escrow Fund unless and until a certificate
signed by an officer of Acquiror (an "Officer's Certificate") identifying
Damages has been delivered to the Escrow Agent and such amount is determined
pursuant to this Section 8 to be payable, in which case Acquiror shall receive a
proportional amount of escrowed shares and escrowed cash from the Escrow Fund
equal in value to the full amount of such Damages without deduction. In
determining the amount of any Damages attributable to a breach, any materiality
standard contained in any representation, warranty or covenant of Target and
Target Stockholder shall be disregarded.

                8.5 ESCROW PERIOD. Subject to the following requirements, the
Escrow Fund shall remain in existence until the Escrow Termination Date (the
"Escrow Period"). Upon the expiration of the Escrow Period, the Escrow Fund
shall terminate; provided, however, that the the number of escrowed shares in
the Escrow Fund, which, in the reasonable judgment of Acquiror, subject to the
objection of Target Stockholder and the subsequent arbitration of the claim in
the manner provided herein, are necessary to satisfy any unsatisfied claims
specified in any Officer's Certificate delivered to the Escrow Agent prior to
the expiration of such Escrow Period with respect to facts and circumstances
existing on or prior to the Escrow Termination Date shall remain in the Escrow
Fund (and the Escrow Fund shall remain in existence) until such claims have been
resolved. As soon as all such claims have been resolved, the Escrow Agent

                                       43
<PAGE>   45

shall deliver to Target Stockholder all escrowed cash, escrowed shares and other
property remaining in the Escrow Fund and not required to satisfy such claims.

                8.6 METHOD OF ASSERTING CLAIMS. In the event any Parent
Indemnified Person (the "Claiming Person") asserts a right of indemnity against
the Target Stockholder under this Section 8, Acquiror or Merger Sub shall
execute and deliver to the Target Stockholder a written notice to such effect (a
"Notice of Claim"; and the right of indemnity asserted in a Notice of Claim
being hereinafter referred to as a "Claim") and instruct the Escrow Agent to
deliver that portion of the Escrow Fund the Fair Market Value (as defined below)
of which shall equal the amount of the Claim to such Claiming Person.

                8.7 CASH PAYMENTS. Upon receipt of a Notice of Claim, Target
Stockholder shall have the right and option to elect to make a cash payment
within five (5) business days of receipt of the Notice of Claim. In the event
the Target Stockholder makes a cash payment to the Indemnified Person in
settlement of any Claim asserted in a Notice of Claim, then the Escrow Agent
shall release a number of shares of escrowed shares in the Escrow Fund to the
Target Stockholder in an amount equal to the quotient of (A) the total amount of
the cash payment divided by (B) the Fair Market Value per share. Target
Stockholder shall have no right or entitlement to replace escrowed shares with
cash, other than in connection with a Notice of Claim and only up to the total
amount of such Claim.

                8.8 DEFINITION OF "FAIR MARKET VALUE". For purposes of this
Section 8, "Fair Market Value" shall mean (i) (A) if the Common Stock of the
Acquiror is not then traded on a national securities exchange, the average of
the closing prices quoted on the National Association of Securities Dealers,
Inc. Automated Quotation National Market System, if applicable, or the average
of the last bid and asked prices of the Common Stock quoted in the
over-the-counter-market or (B) if the Common Stock is then traded on a national
securities exchange, the average of the high and low prices of the Common Stock
listed on the principal national securities exchange on which the Common Stock
is so traded, in each case for the five (5) trading days immediately preceding
the date of the Notice of Claim or, if such date is not a business day on which
shares are traded, the next immediately preceding trading day or (ii) in all
other circumstances, the fair market value per share of Common Stock as
determined by the Acquiror's Board of Directors.

                8.9 INDEMNIFICATION ACQUIROR.

                        (a) INDEMNIFIED DAMAGES. Subject to the limitations set
forth in this Section 8, from and after the Effective Time, Acquiror shall
protect, defend, indemnify and hold harmless Target (in the event that Merger
does not Close) Target Stockholders and their respective affiliates, officers,
directors, employees, representatives and agents (Target, Target Stockholders
and each of the foregoing persons or entities is hereinafter referred to
individually as an "Indemnified Person" and collectively as "Indemnified
Persons") from and against any and all losses, costs, damages, liabilities, fees
(including without limitation attorneys' fees) and expenses (collectively, the
"Damages"), that any of the Indemnified Persons incurs by reason of or in
connection with any claim, demand, action or cause of action alleging
misrepresentation, breach of, or default in connection with, any of the
representations, warranties, covenants or agreements of Acquiror and Merger Sub
contained in this Agreement, including any exhibits or

                                       44
<PAGE>   46

schedules attached hereto, and the Certificate of Merger, which becomes known to
Target or Target Shareholders during the Escrow Period. Damages in each case
shall be net of the amount of any insurance proceeds and indemnity and
contribution actually recovered by Target or Target Shareholders.

                        (b) LIMITATIONS. The maximum liability of Acquiror and
Merger Sub for any breach of a representation, warranty or covenant of Acquiror
or Merger Sub shall be limited to the amount of $400,000 in the aggregate;
provided, however, that nothing herein shall limit the liability of any officer,
director or Acquiror for such person's or entity's fraud or intentional
misrepresentation.

                            STOCK PURCHASE AGREEMENT

               THIS STOCK PURCHASE AGREEMENT (this "AGREEMENT") is entered into
as of this 8th day of November 1999 (the "EFFECTIVE DATE") by and among PROGRAPH
SYSTEMS, INC., a Pennsylvania corporation (the "COMPANY"), and WILLIAM GUTTMAN
(the "PURCHASER").

               WHEREAS, the Purchaser desires to purchase 1,654,702 shares of
the Company's common stock (the "COMMON STOCK") (such number of shares owned by
the Purchaser and any shares of capital stock of the Company acquired by the
Purchaser as a result of any subdivision, combination or reclassification of
outstanding shares of Common Stock into a greater or smaller number of shares,
recapitalization, reorganization, reclassification of shares, stock dividend or
like event (collectively, "RECAPITALIZATION EVENTS"), being hereinafter referred
to as the "SHARES");

               NOW, THEREFORE, in consideration of the mutual covenants and
representations herein set forth, the parties hereto hereby agree as follows:

               1. PURCHASE OF SHARES. As of the Effective Date and subject to
the terms and conditions of this Agreement, Purchaser hereby purchases from the
Company, and Company hereby sells to Purchaser, an aggregate of 1,654,702 shares
of the Company's common stock at an aggregate purchase price of $380,581.16 (the
"PURCHASE PRICE") or $0.23 per Share (the "PURCHASE PRICE PER SHARE").

               2. PAYMENT OF PURCHASE PRICE; CLOSING.

                      (a) DELIVERIES BY PURCHASER. Purchaser hereby delivers to
the Company the full Purchase Price by signing and delivery the form of
promissory note attached as Exhibit A (the "PROMISSORY NOTE"). Purchaser also
hereby delivers to the Company two (2) copies of the Pledge Agreement in the
form of Exhibit B (the "PLEDGE AGREEMENT") a blank Stock Power and Assignment
Separate from Stock Certificate in the form of Exhibit C attached hereto (the
"STOCK POWERS"), both executed by Purchaser.

                      (b) DELIVERIES BY THE COMPANY. Upon its receipt of the
entire Purchase Price and all the documents to be executed and delivered by
Purchaser to the Company under Section 2(a), the Company will issue a duly
executed stock certificate evidencing the Shares registered in Purchaser's name
in accordance with Section 14 with such certificate to be placed in escrow as
provided in the Pledge Agreement.

               3. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser
represents and warrants to the Company that:

                      (a) Purchase for Own Account for Investment. Purchaser is
purchasing the Shares for Purchaser's own account for investment purposes only
and not with a view to, or for sale in connection with, a distribution of the
Shares within the meaning of the

<PAGE>   2
Securities Act of 1933, as amended (the "1933 ACT"). Purchaser has no present
intention of selling or otherwise disposing of all or any portion of the Shares
and no one other than Purchaser has any beneficial ownership of any of the
Shares.

                      (b) Access to Information. Purchaser has had access to all
information regarding the Company and its present and prospective business,
assets, liabilities and financial condition that Purchaser reasonably considers
important in making the decision to purchase the Shares, and Purchaser has had
ample opportunity to ask questions of the Company's representatives concerning
such matters and this investment.

                      (c) Understanding of Risks. Purchaser is fully aware of:
(i) the highly speculative nature of the investment in the Shares; (ii) the
financial hazards involved; (iii) the lack of liquidity of the Shares and the
restrictions on transferability of the Shares (e.g., that Purchaser may not be
able to sell or dispose of the Shares or use them as collateral for loans); (iv)
the qualification and backgrounds of the management of the Company; and (v) the
tax consequences of investment in the Shares.

                      (d) Purchaser's Qualifications. Purchaser has a
preexisting personal or business relationship with the Company and/or certain of
its officers and/or directors of a nature and duration sufficient to make
Purchaser aware of the character, business acumen and general business and
financial circumstances of the Company and/or such officers and directors. By
reason of Purchaser's business or financial experience, Purchaser is capable of
evaluating the merits and risks of this investment, has the ability to protect
Purchaser's own interests in this transaction and is financially capable of
bearing a total loss of this investment. Purchaser is an "accredited investor"
as defined under Rule 501 promulgated under the Securities Act of 1933, as
amended.

                      (e) No General Solicitation. At no time was Purchaser
presented with or solicited by any publicly issued or circulated newspaper,
mail, radio, television or other form of general advertising or solicitation in
connection with the offer, sale and purchase of the Shares.

                      (f) Compliance with Securities Laws. Purchaser understands
and acknowledges that, in reliance upon the representations and warranties made
by Purchaser herein, the Shares are not being registered with the Securities and
Exchange Commission ("SEC") under the 1933 Act, but instead are being issued
under an exemption or exemptions from the registration and qualification
requirements of the 1933 Act or applicable state securities laws which impose
certain restrictions on Purchaser's ability to transfer the Shares.

                      (g) Restrictions on Transfer. Purchaser understands that
Purchaser may not transfer any Shares unless such Shares are registered under
the 1933 Act or qualified under the Law or unless, in the opinion of counsel to
the Company, exemptions from such registration and qualification requirements
are available. Purchaser understands that only the Company may file a
registration statement with the SEC and that the Company is under no obligation
to do so with respect to the Shares. Purchaser has also been advised that
exemptions

                                       2

from registration and qualification may not be available or may not permit
Purchaser to transfer all or any of the Shares in the amounts or at the time
proposed by Purchaser.

                      (h) Rule 144. In addition, Purchaser has been advised that
SEC Rule 144 promulgated under the 1933 Act, which permits certain limited sales
of unregistered securities, is not presently available with respect to the
Shares and, in any event, currently requires that the Shares be held for a
minimum of one year, and in certain cases two years, after they have been
purchased and paid for (within the meaning of Rule 144), before they may be
resold under Rule 144. Purchaser understands that Rule 144 may indefinitely
restrict transfer of the Shares so long as Purchaser remains an "affiliate" of
the Company and "current public information" about the Company (as defined in
Rule 144) is not publicly available.

               4. RIGHTS AS STOCKHOLDER. Subject to the terms and conditions of
this Agreement, Purchaser will have all of the rights of a stockholder of the
Company with respect to the Shares from and after the date that Purchaser
delivers payment of the Purchase Price until such time as Purchaser disposes of
the Shares or the Company and/or its assignee(s) exercise(s) the repurchase
options hereunder. Upon an exercise of any right to repurchase hereunder,
Purchaser will have no further rights as a holder of the Shares so purchased
upon such exercise, except the right to receive payment for the Shares so
purchased in accordance with the provisions of this Agreement, and Purchaser
will promptly surrender the stock certificate(s) evidencing the Shares so
purchased to the Company for transfer or cancellation.

               5. RESTRICTIVE LEGEND AND STOP-TRANSFER ORDERS.

                (a)     LEGEND. Purchaser understands and agrees that the
                        Company will place the legend set forth below or a
                        similar legend on any stock certificate(s) evidencing
                        the Shares, together with any other legends that may be
                        required by state or federal securities laws, the
                        Company's Articles of Incorporation or Bylaws, any other
                        agreement between Purchaser and the Company or any
                        agreement between Purchaser and any third party:

                THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
                THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE
                SECURITIES LAWS OF ANY STATE. THESE SECURITIES ARE SUBJECT TO
                RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE
                TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND
                APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR
                EXEMPTION THEREFROM.

                (b)     STOP-TRANSFER INSTRUCTIONS. Purchaser agrees that, in
                        order to insure compliance with the restrictions imposed
                        by this Agreement, the Company may issue appropriate
                        "stop-transfer" instructions to its transfer agent, if
                        any, and if the Company transfers its own securities, it
                        may make appropriate notations to the same effect in its
                        own records.

                (c)     REFUSAL TO TRANSFER. The Company will not be required
                        (i) to transfer on its books any Shares that have been
                        sold or otherwise transferred in violation of any of the
                        provisions of this Agreement or (ii) to treat as owner
                        of such Shares, or to accord the right to vote or pay
                        dividends, to any purchaser or other transferee to whom
                        such Shares have been so transferred.

               6. MARKET STANDOFF AGREEMENT. Purchaser agrees in connection with
any registration of the Company's securities under the 1933 Act that, upon the
request of the Company or the underwriters managing any registered public
offering of the Company's securities, Purchaser will not sell or otherwise
dispose of any Shares without the prior written consent of the Company or such
managing underwriters, as the case may be, for a period of time (not to exceed
180 days) after the effective date of such registration requested by such
managing underwriters and subject to all restrictions as the Company or the
managing underwriters may specify for employee-shareholders generally.

               7. COMPLIANCE WITH LAWS AND REGULATIONS. The issuance and the
transfer of the Shares will be subject to and conditioned upon compliance by the
Company and Purchaser with all applicable state and federal laws and regulations
and with all applicable requirements of any stock exchange or automated
quotation system on which the Company's common stock may be listed or quoted at
the time of such issuance or transfer.

               8. SUCCESSORS AND ASSIGNS. The Company may assign any of its
rights under this Agreement, including its rights to repurchase Shares
hereunder. This Agreement will be binding upon and inure to the benefit of the
successors and assigns of the Company. Subject to the restrictions on transfer
herein set forth, this Agreement will be binding upon Purchaser and Purchaser's
heirs, executors, administrators, successors and assigns.

               9. GOVERNING LAW; SEVERABILITY. This Agreement will be governed
by and construed in accordance with the internal laws of the Commonwealth of
Pennsylvania, excluding that body of laws pertaining to conflict of laws. If any
provision of this Agreement is determined by a court of law to be illegal or
unenforceable, then such provision will be enforced to the maximum extent
possible and the other provisions will remain fully effective and enforceable.

               10. NOTICES. Any notice required or permitted hereunder will be
given in writing and will be deemed effectively given upon personal delivery,
three (3) days after deposit in the United States mail by certified or
registered mail (return receipt requested), one (1) business day after its
deposit with any return receipt express courier (prepaid), or one (1) business
day after transmission by telecopier, addressed to the other party at its

shown below its signature to this Agreement, or to such other address as such
party may designate in writing from time to time to the other party.

               11. FURTHER INSTRUMENTS. The parties agree to execute such
further instruments and to take such further action as may be reasonably
necessary to carry out the purposes and intent of this Agreement.
