                   SUBORDINATED NON-NEGOTIABLE PROMISSORY NOTE

$3,979,800                                                        March 10, 2000

          PRINTCAFE, INC., a Delaware corporation (the "Company"), for value
received, hereby promises to pay RICHARD T. HAGEN (the "Holder"), or permitted
registered assigns, the principal sum equal to THREE MILLION NINE HUNDRED
SEVENTY-NINE THOUSAND EIGHT HUNDRED DOLLARS ($3,979,800). This Note is issued
pursuant to the Agreement and Plan of Merger dated as of February 22, 2000 (the
"Merger Agreement"), among the Company, Hagen Systems, Inc., a Minnesota
corporation ("Hagen"), the stockholders of Hagen, including the Holder, and
printCafe Systems, Inc., a Delaware corporation wholly-owned by the Company, and
is subject to the provisions thereof. Terms used but not defined herein shall
have the meanings set forth in the Merger Agreement.

        THIS NOTE SHALL NOT BE NEGOTIABLE, ASSIGNABLE OR OTHERWISE TRANSFERABLE
WITHOUT THE EXPRESS PRIOR WRITTEN CONSENT OF THE COMPANY.

1.      PRINCIPAL AND INTEREST. This Note shall be payable in three equal
successive instalments on the first, second and third (3rd) anniversaries of the
date hereof upon delivery of a notice (the "Payment Notice") from the Holder to
the Company specifying the time, place and manner of payment. The unpaid
principal amount of this Note shall bear interest at a rate of interest for each
quarterly period commencing on the date hereof equal to the lower of (i) the
Prime Rate, as published in the Wall Street Journal on the first business day of
such quarter or (ii) 9.0% per annum. Interest shall be payable quarterly in
arrears on the same day in each successive February, May, August, and November
as the date hereof (except that if any such date is not a business day, such
payment shall be made on the next succeeding business day), with a final payment
on the final maturity date.

2.      SECURITY. Payment and performance of this Note is not secured.

3.      PREPAYMENT. The Company may prepay, in whole or in part, the outstanding
amount of this Note at any time or from time to time without penalty or premium.

4.      MANDATORY PREPAYMENT. Simultaneously with the consummation of a firmly
underwritten initial public offering registered pursuant to the Securities Act
of 1933, as amended (the "Securities Act"), of shares of common stock of the
Company, the Company shall prepay such portion of the principal of this Note as
is necessary to reduce the remaining principal hereof to 50% of the original
face amount hereof, which prepayment shall be applied to reduce equally each of
the remaining scheduled repayments of principal hereunder. In addition,
simultaneously with the consummation of a subsequent firmly underwritten public
offering by the Company of shares of its common stock pursuant to a registration
statement under the Securities Act which results in aggregate gross cash
proceeds to the Company of at least $125 million, the Company shall prepay in
full the remaining principal outstanding under this Note. Each prepayment shall
be made together with interest accrued on the principal so prepaid.

5.      RESTRICTIONS ON TRANSFER.

        (a) THIS NOTE SHALL NOT BE NEGOTIABLE, ASSIGNABLE OR OTHERWISE
TRANSFERABLE WITHOUT THE EXPRESS PRIOR WRITTEN CONSENT OF THE COMPANY.

        (b) The Company shall keep at its principal executive office a register
(herein sometimes referred to as the "Note Register"), in which, subject to such
reasonable regulations as it may prescribe, but at its expense (other than
transfer taxes, if any), the Company shall provide for the registration and
transfer of this Note.

        (c) Subject to Section 5(a) hereof, whenever this Note shall be
surrendered at the principal executive office of the Company for transfer,
accompanied by (i) a written instrument of transfer in form reasonably
satisfactory to the Company duly executed by the holder or his attorney duly
authorized in writing, (ii) the written opinion, addressed to the Company, of
counsel for the holder of this Note, stating that in the opinion of such counsel
(which opinion and counsel shall be reasonably satisfactory to the Company),
such proposed transfer does not involve any transaction requiring registration
or qualification of such shares under the Securities Act or the securities blue
sky laws of any relevant state of the United States and (iii) a writing duly
executed by the transferee acknowledging that this Note is issued pursuant to
the Merger Agreement and is subject to the provisions thereof and agreeing to be
bound by the terms hereof and thereof, including, without limitation, the
provisions of this Section 5 and Section 8 hereof, the Company shall execute and
deliver in exchange therefor a new Note or Notes, as may be requested by such
holder, in the same aggregate unpaid amount and payable on the same date as the
Note or Notes so surrendered; each such new Note shall be dated as of the date
to which payments have been made on the Note or Notes so surrendered and shall
be in such amount and registered in such name or names as such holder may
designate in writing.

        (d) Upon receipt by the Company of evidence reasonably satisfactory to
it of the loss, theft, destruction or mutilation of this Note and of indemnity
reasonably satisfactory to it, and upon reimbursement to the Company of all
reasonable expenses incidental thereto, and upon surrender and cancellation of
this Note (in case of mutilation), the Company will make and deliver in lieu of
this Note a new Note of like tenor and unpaid amount and dated as of the date
hereof.

or the reorganization, readjustment or the release of debtors to be instituted
against it and if contested by it not dismissed or stayed within ninety (90)
days; or

        (f) if proceedings under any law related to bankruptcy, insolvency,

7.      SUBORDINATION.

        (a) General. The Company, for itself, its successors and assigns,
covenants and agrees, and the Holder by its acceptance hereof covenants and
agrees, that this Note shall be subordinated to the extent set forth in this
Section to the prior payment in full of all Senior Debt (as defined below) as
follows:

               (i) In the event of an Event of Default specified in Sections
        7(b), (e) or (f) hereof, the Holder shall not be entitled to receive any
        payment on account of principal of or interest on this Note unless and
        until the Senior Debt shall have been paid in full. To that end, the
        holders of Senior Debt shall be entitled to receive for application in
        payment thereof any payment or distribution of any kind or character,
        whether in cash, property or securities, which may be payable or
        deliverable in any such proceedings in respect of this Note.

<PAGE>   4

               (ii) If any Senior Debt or this Note is declared due and payable
        prior to its stated maturity by reason of an Event of Default specified
        in Sections 7(a), (c), (d) or (g) hereof or like provisions in
        instruments evidencing the Senior Debt, then all of the Senior Debt
        shall first be paid in full, before any payment on account of principal
        of or interest on this Note may be made.

               (iii) If the Company fails to pay any principal of or interest
        (or premium, if any) on any Senior Debt when due, under circumstances
        when the provisions of clauses (i) and (ii) hereof shall not be
        applicable, then all principal of and interest (or premium, if any) on
        such Senior Debt then due and payable shall first be paid in full,
        before any payment on account of principal of or interest on this Note
        may be made.

               (iv) The provisions of clauses (i) through (iii) shall not
        prohibit the Company from issuing to the Holder securities of the
        Company which are subordinate and junior in right of payment to all
        Senior Debt then outstanding, on the same terms as set forth in this
        Section 8, in exchange for and in satisfaction of the indebtedness
        represented by this Note.

        (b) "Senior Debt" means all amounts (including any interest accruing
thereon) owed under the following, whether now outstanding or hereafter
incurred, created or assumed:

               (i) indebtedness pursuant to the Term Loan Agreement, dated July,
        6, 1999, between the Company and National City Bank secured by a general
        security interest in all assets, except intellectual property, of the
        Company, in the amount of $900,000.;

               (ii) all indebtedness under securities issued pursuant to a
        public offering registered under the Securities Act;

               (iii) any line or lines of credit or other indebtedness for
        borrowed money incurred by the Company on or after the date hereof (A)
        for working capital purposes and/or (B) for refinancing, refunding or
        replacement of Senior Debt and/or (C) extended by one or more banks; and

               (iv) all guaranties by the Company of the principal of and
        interest and premium (if any) on any indebtedness of any subsidiary or
        affiliate of the Company which constitutes "Senior Debt" pursuant to
        clauses (i) through (iii) hereof, which is guaranteed by the Company.

        (c) Further Assurances. The Holder hereby agrees to execute and deliver
all documents, and take all actions necessary or desirable, as reasonably
requested by the Company to affect the provisions of the this Section 8,
including, without, executing and delivering intercreditor or other agreements
among or between the Holder and any holder of Senior Debt of the Company or its
subsidiaries or affiliates.

                  (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

(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 CSINH have
been duly filed on a timely basis, and each such Return is true, complete and
correct in all material respects. All Taxes shown to be payable on such Returns
or on subsequent assessments with respect thereto, and all payments of estimated

        (c) The amount of CSINH's liabilities for unpaid Taxes for all periods
through the date of the CSINH Financial Statements do not, in the aggregate,
materially exceed the amount of the current liability accruals for Taxes
reflected on the CSINH Financial Statements, and the CSINH Financial Statements
properly accrue in accordance with GAAP all liabilities for Taxes of CSINH
payable after the date of the CSINH Financial Statements attributable to

taxing authority is in process, threatened or, to CSI or CSINH's knowledge,

informally) against CSINH, or any of its assets. No waiver or extension of any
statute of limitations is in effect with respect to Taxes or Returns of CSINH.

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.

Company, there have been no written notices, citations or decisions by any
governmental or regulatory body that any product produced, manufactured,

all applicable licenses, registrations, approvals, clearances and authorizations
required by local, state or federal agencies in such countries regulating the

        3.12 TITLE TO PROPERTY.

             (a) The Company (or a Subsidiary) has good and marketable title to
all of its properties, interests in properties and assets, real and personal,

leasehold interests in, free and clear of all mortgages, liens, pledges, charges

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

equipment of the Company and each Subsidiary that are used in the operations of
its businesses are in good operating condition and repair. All properties used

of all real property owned or leased by the Company or any Subsidiary, 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).

             (b) Section 3.12(b) of the Disclosure Schedule also sets forth a
true, correct and complete list of all equipment having a value in excess of
$1,000 owned or leased the Company or any Subsidiary, and such equipment is,

operating condition (except for ordinary wear and tear).

        3.13 INTELLECTUAL PROPERTY.

             (a) Each of the Company and each Subsidiary owns, or has licensed
or otherwise possess 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 ("Intellectual Property") that
are used or proposed to be used in the business of the Company or any Subsidiary
as currently conducted by the Company or such Subsidiary.

             (b) Section 3.13 of the 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
registered by the Company or any Subsidiary, 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 the Company is a party and pursuant to which any
person is authorized to use any Intellectual Property except for licenses to
customers granted in the ordinary course of business, and (iii) all material
licenses, sublicenses and other agreements as to which the Company or any
Subsidiary is a party and pursuant to which any person is authorized the 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 product that is material to its business, excluding Third Party Intellectual
Property Rights for word processing software or similar software validly
obtained and licensed by the Company. Neither the Company nor any Subsidiary is
in violation of any license, sublicense or agreement described in Section 3.13
of the Disclosure Schedule. The execution and delivery of this Agreement by the
Company and the consummation of the transactions contemplated hereby, will
neither cause the Company or any Subsidiary 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 3.13 of the Disclosure
Schedule, the Company (or a Subsidiary) 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 the Intellectual Property is being
used.

             (c) There is no material unauthorized use, disclosure, infringement
or misappropriation of any Intellectual Property rights of the Company or any
Subsidiary, any trade secret material to the Company or any Subsidiary or any
Intellectual Property right of any third party to the extent licensed by or
through the Company or any Subsidiary, by any third party, including any
employee of the Company or any Subsidiary. Neither the Company nor any
Subsidiary has entered into any agreement to indemnify any other person against
any charge of

                                       18
<PAGE>   23

infringement of any Intellectual Property, other than indemnification provisions
contained in purchase orders arising in the ordinary course of business.

             (d) Neither the Company nor any Subsidiary is nor will be as a
result of the execution and delivery of this Agreement or the performance of the
Company's obligations 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 the Company.

             (e) All patents, registered trademarks, service marks and
copyrights held by the Company and each Subsidiary are valid and existing and,
to the knowledge of the Company, there is no assertion or claim (or basis
therefor) challenging the validity of any Intellectual Property of the Company
or any Subsidiary. Neither the Company nor any Subsidiary has 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 the Company or any Subsidiary as currently conducted nor the
manufacture, sale, licensing or use of any of the products of the Company or any
Subsidiary 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 the
Company or any Subsidiary 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, patent, patent right, industrial model,
invention, service mark or copyright of any third party that, individually or in
the aggregate, is reasonably likely to have a Material Adverse Effect on the
Company. All registered trademarks, service marks and copyrights held by the
Company or any Subsidiary are valid and existing. To the Company's knowledge, no
third party is challenging the ownership by the Company, or the validity or
effectiveness of, any of the Intellectual Property. The Company 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 knowledge of the Company,
threatened interference, re-examinations, oppositions or nullities involving any
patents, patent rights or applications therefor of the Company except such as
may have been commenced by the Company. There is no breach or violation of or,
to the knowledge of the Company, threatened or actual loss of rights under any
license agreement to which the Company is a party.

             (f) Each of the Company and each Subsidiary has secured valid
written assignments from all consultants and employees who contributed to the
creation or development of Intellectual Property of the rights to such
contributions that the Company (or a Subsidiary) does not already own by
operation of law.

             (g) Each of the Company and each Subsidiary has a policy requiring
each employee, consultant and independent contractor to execute proprietary
information and confidentiality agreements substantially in the Company's or
such Subsidiary's standard forms and all current and former employees,
consultant and independent contractors of the Company and such Subsidiary have
executed such an agreement. All use, disclosure or appropriation of the
Intellectual Property owned by the Company or any Subsidiary and not otherwise
protected by patents, patent applications or copyright ("Confidential
Information") has been pursuant to the terms of a written agreement between the
Company or a Subsidiary and a third party. All

                                       19
<PAGE>   24

use, disclosure or appropriation by the Company or any Subsidiary of
Confidential Information not owned by the Company or a Subsidiary has been
pursuant to the terms of a written agreement between the Company or such
Subsidiary and the owner of such Confidential Information, or is otherwise
lawful.

failure to timely file such Return will not have a Material Adverse Effect on
the Company, and each such Return is true, complete and correct in all material

Taxes of the Company or any Subsidiary, and neither the Company nor any
Subsidiary has received notice (either in writing or orally, formally or

orally, formally or informally) against the Company or any Subsidiary or any of
their respective assets. No waiver or extension of any statute of limitations is
in effect with respect to Taxes or Returns of the Company or any Subsidiary. The
Company has disclosed on their 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.

             (e) The Company is not (nor has it ever been) a party to any tax
sharing agreement. Since January 1, 1998, the Company has never been a
distributing corporation or a controlled corporation in a transaction described

The Company is not a "consenting corporation" under Section 341(f) of the Code.
The Company has not entered into any compensatory agreements with respect to the
performance of services which payment thereunder would result in a nondeductible
expense to the Company pursuant to Section 280G of the Code or an excise tax to
the recipient of such payment pursuant to Section 4999 of the Code. The Company
has agreed to, nor is it required to make, other than by reason of the
transactions contemplated hereunder, any adjustment under Code Section 481(a) by
reason of, a change in accounting method, and the Company will not otherwise

occurring prior to the Closing Date with respect to which the Company received
the economic benefit prior to the Closing Date. The Company 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.

             (g) The Disclosure Schedule contains accurate and complete

        3.16 EMPLOYEE BENEFIT PLANS.

             (a) Schedule 3.16 lists, with respect to the Company and any trade
or business (whether or not incorporated) which is treated as a single employer
with CSINH (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 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 the Company (other than, in each case, any such
contract or agreement that is terminable by the Company 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 the Company 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 the Company remain for the benefit of, or relating to, any
present or former employee, consultant or director of the Company (together, the
"Employee Plans").

             (b) The Company has furnished to the Acquiror a copy of each of the
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 Employee
Plan which is subject to ERISA reporting requirements, provided copies of the
Form 5500 reports filed for the last three plan years. Any 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 with
the exception of any amendments required by such subsequent legislation for
which the period during which a determination letter may be requested from the
Internal Revenue Service has not yet expired under such applicable Treasury
regulation or Internal Revenue Service pronouncements. The Company has also
furnished the Acquiror with the most recent Internal Revenue Service
determination letter issued with respect to each such Employee Plan, and nothing
has occurred since the issuance of each such letter which could reasonably be
expected to cause the loss of the tax-qualified status of any Employee Plan
subject to Code Section 401(a). This Section 3.16(b) is limited by the
disclosure set forth in Section 3.16(b) of the Disclosure Schedule.

             (c) Except as set forth in Section 3.16(c) of the Disclosure
Schedule, (i) none of the Employee Plans promises or provides retiree medical or
other retiree welfare or life insurance benefits to any person; (ii) there has
been no "prohibited transaction," as such term is defined in Section 406 of
ERISA and Section 4975 of the Code, with respect to any Employee

                                       23
<PAGE>   28

Plan, which could reasonably be expected to have, in the aggregate, a Material
Adverse Effect; (iii) each Employee Plan has been administered in accordance
with its terms and in compliance with the requirements prescribed by any and all
statutes, rules and regulations (including ERISA and the Code), except as would
not have, in the aggregate, a Material Adverse Effect, and the Company has
performed all obligations required to be performed by them under, are not in any
material respect in default under or violation of, and have no knowledge of any
material default or violation by any other party to, any of the Employee Plans;
(iv) neither the Company nor any ERISA Affiliate is subject to any liability or
penalty under Sections 4976 through 4980 of the Code or Title I of ERISA with
respect to any of the Employee Plans; (v) all material contributions required to
be made by the Company or ERISA Affiliate to any Employee Plan have been made on
or before their due dates and a reasonable amount has been accrued for
contributions to each Employee Plan for the current plan years; (vi) with
respect to each Employee Plan, no "reportable event" within the meaning of
Section 4043 of ERISA (excluding any such event for which the thirty day notice
requirement has been waived under the regulations to Section 4043 of ERISA) nor
any event described in Section 4062, 4063 or 4041 or ERISA has occurred; (vii)
no Employee Plan is covered by, and neither the Company nor any ERISA Affiliate
has incurred or expects to incur any direct or indirect liability under, arising
out of or by operation of Title IV of ERISA in connection with the termination
of, or an employee's withdrawal from, any Employee Plan or other retirement plan
or arrangement, and no fact or event exists that could give rise to any such
liability, or under Section 412 of the Code; (viii) the Company has not incurred
any liability under, and have complied in all respects with, the Worker
Adjustment Retraining Notification Act, (the "WARN Act")and no fact or event
exists that could give rise to liability under such act; and (ix) no
compensation paid or payable to any employee of the Company has been, or will
be, non-deductible by reason of application of Section 162(m) of the Code. With
respect to each Employee Plan subject to ERISA as either an employee pension
plan within the meaning of Section 3(2) of ERISA or an employee welfare benefit
plan within the meaning of Section 3(1) of ERISA, the Company has prepared in
good faith and timely filed all requisite governmental reports (which were true
and correct as of the date filed to the best of the Company's knowledge) and has
properly and timely filed and distributed or posted all notices and reports to
employees required to be filed, distributed or posted with respect to each such
Employee Plan, except to the extent that the failure to comply would not, in the
aggregate, have a Material Adverse Effect. No suit, administrative proceeding,
action or other litigation has been brought, or to the best knowledge of the
Company is threatened, against or with respect to any such Employee Plan,
including any audit or inquiry by the IRS or United States Department of Labor.
Neither the Company or any ERISA Affiliate is a party to, or has made any
contribution to or otherwise incurred any obligation under, any "multiemployer
plan" as defined in Section 3(37) of ERISA.

             (d) With respect to each Employee Plan, the Company has complied
with (i) the applicable health care continuation and notice provisions of the
Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA") and the
proposed regulations thereunder and (ii) the applicable requirements of the
Family Leave Act of 1993 and the regulations thereunder, except to the extent
that such failure to comply would not, in the aggregate, have a Material Adverse
Effect.

             (e) The consummation of the transactions contemplated by this
Agreement will not (i) entitle any current or former employee or other service
provider of the Company or

                                       24
<PAGE>   29

any ERISA Affiliate to severance benefits or any other payment (including,
without limitation, unemployment compensation, golden parachute or bonus),
except as expressly provided in this Agreement, or (ii) accelerate the time of
payment or vesting of any such benefits, or increase the amount of compensation
due any such employee or service provider.

             (f) There has been no amendment to, written interpretation or
announcement (whether or not written) by the Company or any ERISA Affiliate
relating to, or change in participation or coverage under, any Employee Plan
which would materially increase the expense of maintaining such Plan above the
level of expense incurred with respect to that Plan for the most recent fiscal
year included in the Company's financial statements.

        3.17 CERTAIN AGREEMENTS AFFECTED BY THE SALE. Neither the execution and
delivery of this Agreement nor the consummation of the transactions contemplated
hereby will (i) result in any payment (including, without limitation, severance,
unemployment compensation, golden parachute, bonus or otherwise) becoming due to
any director or employee of the Company, (ii) materially increase any benefits
otherwise payable by the Company, or (iii) result in the acceleration of the
time of payment or vesting of any such benefits.

        3.18 EMPLOYEE MATTERS. The Company and each Subsidiary is in compliance
in all material respects with all currently applicable federal, state, local and
foreign laws and regulations respecting employment, discrimination in
employment, terms and conditions of employment, wages, hours and occupational

hereunder.

        8.2 EFFECT OF TERMINATION. In the event of termination of this Agreement
as provided in Section 8.1, this Agreement shall forthwith become void and there
shall be no liability or obligation on the part of any party hereto or their
respective officers, directors, stockholders or affiliates, except to the extent
that such termination results from the breach by a party hereto of any of its
representations, warranties or covenants set forth in this Agreement; provided

SECTION 9. ESCROW AND INDEMNIFICATION.

        9.1 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All covenants to be
performed prior to the Closing Date, and all representations and warranties in
this Agreement or in any instrument delivered pursuant to this Agreement shall
survive the Closing Date and continue until the twelve (12) month anniversary
thereof (the "Escrow Termination Date"), except for the representations and
warranties contained in Section 2 as to CSINH and Sections 3.3, 3.4, 3.13, 3.14,
3.15 and 3.16 hereof, each of which shall survive the Closing Date until the
earlier of December 31, 2006 and the expiration of the applicable statue of
limitations (the "Special Indemnity Termination Date"); provided that if any
claims for indemnification have been asserted with respect to any such
representations and warranties prior the expiration date for such
representations and warranties specified in this Section 9.1, the
representations and warranties on which any such claims are based shall continue
in effect until final resolution of any claims; provided further, that Fraud
Claims (as defined below) shall survive in accordance with the applicable
statute of limitations related to such representations and warranties or such
Fraud Claims. All covenants to be performed after the Effective Time shall
continue indefinitely. "Fraud Claim" shall mean any claim, demand, suit or cause
of action otherwise available to the

                                       45
<PAGE>   50

Indemnified Persons based upon an allegation or allegations that the CSI, CSINH,
the Company and/or and Stockholder had an intent to defraud or made a willful or
intentional misrepresentation or willful omission of a material fact in
connection with this Agreement, including the Exhibits and Schedules attached
hereto, or any of the agreements referred to herein.

        9.2 ESCROW FUND. At the Closing Date, ten percent (10%) of the Share
Consideration and ten percent (10%) of the Other Note Consideration shall, be
registered in the name of, and be deposited with an escrow agent mutually agreed
by the Acquiror and the Founders (the "Escrow Agent"), such deposit to
constitute the escrow fund (the "Escrow Fund"), to be governed by the terms set
forth in an escrow agreement mutually agreeable to the Acquiror and the Founders
upon terms and conditions consistent with the terms and conditions contained in
this Agreement. In the event that any Damages (as defined below) arise, the
Escrow Fund shall be available to compensate the Indemnified Persons (defined
below) pursuant to the indemnification obligations of the Founders pursuant to
Section 9.4. The costs of the Escrow Agent shall be shared equally by the
Acquiror and the Founders.

        9.3 INDEMNIFICATION BY CSI, CSINH, COMPANY AND STOCKHOLDERS.

             (a) INDEMNIFIED DAMAGES. Subject to the limitations set forth in
this Section 9, from and after the Closing Date, CSI and the Stockholders shall
severally protect, defend, indemnify and hold harmless the Acquiror and its
respective affiliates (including CSINH and the Company if the transactions
contemplated hereby are consummated), officers, directors, employees,
representatives and agents (the Acquiror 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 CSI, CSINH, the
Company or the Stockholders contained in this Agreement. For the purposes of
this Agreement, to the extent that the Acquiror suffers any Damages from a
breach of any of the representations and warranties with respect to the Company,
the amount of Damages shall be equal to the Acquiror's ownership percentage of
the Company as of the Closing.

             (b) LIMITATIONS. Except as otherwise provided herein, (i) only CSI
shall be liable for Damages resulting from any misrepresentation of any of the
representations or warranties made in Section 2, (ii) CSI and each Stockholder,
in proportion to the Company Common Stock sold by each, shall be liable for
Damages resulting from any misrepresentation of any of the representations or
warranties made by the Company and (iii) CSI and each Stockholder shall be fully
liable for Damages resulting from any misrepresentation of any of the
representations or warranties made by such party with respect to the Company
Common Stock sold by such party. The maximum liability for any breach of a
representation, warranty or covenant of CSI, CSINH, the Company or the
Stockholders contained in this Agreement, including all Exhibits and Schedules
attached hereto, is limited (1) in the case of CSI, to the Note Consideration
(or, if the claim for Damages is less than the Purchase Price, its proportional
share of such liability where its proportional share is calculated as the Note
Consideration divided by the Purchase Price), (2) in the case of the Founders,
to the Share Consideration (or, if the claim

                                       46
<PAGE>   51

for Damages is less than the Purchase Price, its proportional share of such
liability where its proportional share is calculated as the Share Consideration
divided by the Purchase Price), and (3) in the case of the Other Stockholders,
to that portion of the Other Note Consideration deposited into the Escrow Fund
which amount in the Escrow Fund shall be the exclusive contractual remedy of the
Acquiror against the Other Stockholders for any Damages; provided, however, that
nothing herein shall limit the liability: (i) of any Stockholder in connection
with any breach by such stockholder of its Securities Holder Representation
Agreement, (ii) CSI in connection with any breach of any of the representations
or warranties contained in Section 2 as to CSINH, (iii) of any party in
connection with any breach of any of the representations and warranties
contained in Section 3.3 or 3.4, and (iv) of any party in connection with a
Fraud Claim; and provided further, however, that the indemnities shall not apply
until the aggregate of all claims for Damages exceeds $250,000 (except that the
foregoing monetary limitation of this proviso shall not apply to Damages
attributable to breaches of representations or warranties contained in Section 2
as to CSINH or contained Section 3.3 or 3.4 as to any party). Subject to
compliance with applicable securities laws, any of the Founders may, at his
option, satisfy any Damages for which he is liable by payment of Acquiror
Company Stock, valued at the greater of (i) the price per share at which such
stock was issued pursuant hereto and (ii) if such stock is then publicly-traded,
the fair market value thereof, calculated by the average of the bid price and
ask price as of the business day immediately preceding the date such payment is
to be made. Notwithstanding the foregoing, in no event shall the Founders be
permitted or required to satisfy any Damages by delivering shares of Acquiror
Common Stock in excess of the number of shares received by the Founders pursuant
to this Agreement.

        9.4 DAMAGES THRESHOLD. Notwithstanding the foregoing, the Acquiror may
not receive any amount from the Escrow Fund unless and until a certificate
signed by an officer of the Acquiror (an "Officer's Certificate") identifying
Damages has been delivered to the Escrow Agent and such amount is determined
pursuant to this Section 9 to be payable, in which case the Acquiror shall
receive a proportional amount of the escrowed notes and shares 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 CSI, CSINH,
the Company, the Stockholders or the Acquiror shall be disregarded.

        9.5 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 amount of escrowed shares, notes and cash
in the Escrow Fund, which, in the reasonable judgment of the Acquiror, 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 shall deliver to CSI, the
Founders and the Stockholder Representative, as the case may be, the balance of
the escrowed Share Consideration, Other Note Consideration and other property
remaining in the Escrow Fund and not required to satisfy such claims.

        9.6 DISTRIBUTIONS; VOTING.

             (a) Any shares of Acquiror Common Stock or other equity securities
issued or distributed by Acquiror (including shares issued upon a stock split)
("New Shares") in respect of the shares of the Acquiror's Common Stock initially
deposited into the Escrow Fund (the "Escrow Shares") that have not been released
from the Escrow Fund shall be added to the Escrow Fund and become a part
thereof. When and if cash dividends on Escrow Shares in the Escrow Fund shall be
declared and paid, they shall be retained in escrow pending final distribution
of the Escrow Fund and will not be immediately distributed to the beneficial
owners of the Escrow Shares. Such dividends will become part of the Escrow Fund
and will be available to satisfy Damages. The beneficial owners of the Escrow
Shares shall pay any taxes on such dividends.)

             (b) Each holder of Acquiror Common Stock shall have voting rights
with respect to that number of Escrow Shares contributed to the Escrow Fund on
behalf of such stockholder (and on any voting securities added to the Escrow
Fund in respect of such Escrow Shares) so long as such Escrow Shares or other
voting securities are held in the Escrow Fund. As the record holder of such
shares, the Escrow Agent shall vote such shares in accordance with the
instructions of the stockholders having the beneficial interest therein and
shall promptly deliver copies of all proxy solicitation materials to such
stockholders. The Acquiror shall show the Acquiror Common Stock contributed to
the Escrow Fund as issued and outstanding on its balance sheet.

        9.7 ARBITRATION. Any controversy or claim arising out of or relating to
Damages shall be settled by arbitration in accordance with commercial rules of
the American Arbitration Association ("AAA"). Arbitration proceedings shall be
held in New York, New York. Arbitrations shall be conducted by three arbitrators
(the "Arbitrators") consisting of three independent and impartial arbitrators
appointed by the AAA from a list of arbitrators maintained in the office of the
AAA in New York, New York. No Arbitrator shall be a person who ever has been an
affiliate of or attorney for any party or for any of their respective
affiliates. Any provisional remedy that would be available to a court of law
shall be available from the Arbitrators to the parties pending arbitration. Any
party may, without inconsistency with the Agreement, apply to any court of
proper jurisdiction and seek injunctive relief until the arbitration award is
rendered or the controversy is otherwise resolved. The Arbitrator?s award shall
be made in writing. The Arbitrators shall not modify or amend any of the terms
and conditions contained in this Agreement. The award of the majority of the
arbitrators shall be binding and final and not subject to appeal and may be
entered as a judgment in any court of competent jurisdiction. The parties hereby
irrevocably consent and submit to the jurisdiction of the State of New York for
all purposes relative to any arbitration and to any subsequent entry of judgment
on any award rendered pursuant thereto. Each party hereby waives the benefit of
any applicable law which would permit it to appeal the decision of the
Arbitrator to any court or other authority. All fees and expenses of the
arbitration proceedings shall be borne equally among the parties to the
arbitrations. However, each party shall bear the expense of its own counsel,
experts, witnesses, and preparation and presentation of proofs.
