<PAGE>   4
                            STOCK PURCHASE AGREEMENT


                  THIS STOCK PURCHASE AGREEMENT (this "Agreement") is made and
entered into as of November 4, 1999, by and among J3 Technology Services Corp.,
a Georgia corporation ("Purchaser"), IMPACT INNOVATIONS HOLDINGS, INC., a
Delaware corporation ("Holdings" or "Seller"), IMPACT INNOVATIONS GOVERNMENT
GROUP, INC., a Maryland corporation ("Impact" or the "Company"), and PER-SE
TECHNOLOGIES, INC., a Delaware corporation ("Per-Se").

                                    PREAMBLE

                  Per-Se is the record and beneficial owner of all of the
issued and outstanding shares of Common Stock of Holdings. Holdings is the
record and beneficial owner of all of the issued and outstanding shares of
Common Stock of Impact (the "Shares"). Holdings desires to sell all of the
Shares to the Purchaser, and the Purchaser desires to purchase all of the
Shares from Holdings, upon the terms and subject to the conditions set forth in
this Agreement. The transactions described in this Agreement are subject to the
expiration of the required waiting period under the HSR Act and the
satisfaction of certain other conditions described in this Agreement.
Notwithstanding the foregoing, Purchaser intends at Closing to acquire Assets
of the Company such that the Assets so acquired are from an entity disregarded
as an entity separate from its owner for tax purposes. From and after the
Closing Date, all references to the Company or Impact set forth herein shall
mean and include the LLC as hereinafter defined.

                  Certain terms used in this Agreement are defined in Section
9.1 of this Agreement.

                  NOW, THEREFORE, in consideration of the above and the mutual
warranties, representations, covenants, and agreements set forth herein, the
parties agree as follows:

                                   ARTICLE 1
                               PURCHASE AND SALE

                  1.1      Purchase and Sale. Upon the terms and subject to the
conditions of this Agreement, Holdings shall sell to the Purchaser and the
Purchaser shall purchase from Holdings, the Shares at the closing of the
transactions contemplated hereby (the "Closing"), free and clear of any Liens
(the "Stock Purchase") in exchange for $45 million in cash (the "Initial
Purchase Price"), plus the Conversion Payment, minus the Bonus Accrual and plus
or minus the Working Capital Purchase Price Adjustment as provided in Sections
1.3 and 1.4 respectively (the "Purchase Price").

                  1.2      Time and Place of Closing; Closing Deliveries.

                           (a)      The Closing will take place at 9:00 A.M. on
the Closing Date, or at such other time as the Parties, acting through their
authorized officers, may mutually agree. To the extent not inconsistent with
any other provision of this Agreement, all of the Parties agree that for tax,
accounting and other purposes, the transactions described herein shall be
deemed to have occurred as of the Closing Date, 11:59 p.m., Eastern Time. The
Closing shall be held at the offices of Alston & Bird LLP, One Atlantic Center,
1201 West Peachtree Street, N.W., Atlanta, Georgia, or such other location as
may be mutually agreed upon by the Parties. Subject to the terms and conditions
hereof, unless otherwise mutually agreed upon in writing by the authorized


<PAGE>   5

officers of each Party, the Parties shall use their reasonable efforts to cause
the Closing to occur in December on the first business day following a payroll
date of the Company in the month in which occurs the last to occur of the
effective date (including expiration of any applicable waiting period) of the
last required Consent of any Regulatory Authority having authority over and
approving or exempting the Stock Purchase.

                           (b)      At the Closing:

                                    (i) The Purchaser shall deliver to Per-Se
                           in immediately available funds by wire transfer to
                           an account specified by Per-Se cash in an amount
                           equal to the Initial Purchase Price less the
                           Estimated Bonus Accrual determined in accordance
                           with Section 1.3 below, less the Escrow Amount;

                                    (ii) Per-Se or Holdings shall deliver to
                           the Purchaser (x) certificates representing the
                           Shares duly registered in the name of the Purchaser
                           (or such other Person as the Purchaser may designate
                           to Per-Se not less than five business days prior to
                           the Closing), free and clear of any Liens; and

                                    (iii) The Purchaser shall deliver to the
                           Escrow Agent the Escrow Amount in immediately
                           available funds by wire transfer to be held in
                           escrow pursuant to the terms of the Escrow
                           Agreement. Distribution of the Escrow Amount to
                           either Purchaser, Per-Se or Seller shall be governed
                           by the terms of the Escrow Agreement. Taxes owed on
                           any interest earned on the Escrow Amount shall be
                           paid by Per-Se; and

                                    (iv) the Parties shall deliver the
                           certificates and other documents set forth in
                           Article 6 hereof.

                           (c)      Within ninety (90) days following the
Closing Date, Purchaser or the Company shall pay to Per-Se the Conversion
Payment.

         1.3      Bonus Accrual. The Purchase Price shall be reduced by that
portion of the amount owed to the employees of the Company for the calendar
year 1999 under the Target Performance Bonus Program adjusted to reflect the
portion of the bonus attributable to that portion of the calendar year prior to
the Closing Date (the "Bonus Accrual"). Per-Se will submit to Purchaser a good
faith estimate of the Bonus Accrual within five days prior to Closing (the
"Estimated Bonus Accrual"). To the extent there is a discretionary portion of
the bonus, the Parties shall work in good faith to determine the discretionary
amount.

                  1.4      Working Capital Purchase Price Adjustment.

                           (a)      The "Working  Capital Purchase Price
Adjustment" shall be equal to the Net Working Capital of the Company as of the
Closing Date, as derived from the Closing Balance Sheet (as defined in Section
1.4(b)), minus $8,424,438.

                           (b)      Within ninety (90) days after the Closing
Date, Purchaser will cause to be prepared and delivered to Per-Se an audited
balance sheet of the Company as of the Closing Date (the "Closing Balance
Sheet"), prepared in accordance with GAAP consistently


                                       2
<PAGE>   6

applied and Purchaser's final calculation of the Working Capital Purchase Price
Adjustment and the Bonus Accrual. Purchaser will pay all expenses incurred in
connection with the preparation of the Closing Balance Sheet and Per-Se will
have an opportunity to participate in such audit and review and comment on the
workpapers related thereto prior to the delivery of the Closing Balance Sheet.
Within thirty (30) days after receipt of the Closing Balance Sheet (the
"Notification Period"), Per-Se will notify Purchaser in writing of any
objections Per-Se may have to the Closing Balance Sheet, the Working Capital
Purchase Price Adjustment and the Bonus Accrual. In the absence of such written
objections timely made, Per-Se will be deemed to have approved the Closing
Balance Sheet for purposes of the Working Capital Purchase Price Adjustment, if
any, and the Bonus Accrual to be made pursuant to this Section 1.4 on the
expiration of the Notification Period. If Per-Se timely notifies Purchaser in
writing of objections to the Closing Balance Sheet, the calculation of the
Working Capital Purchase Price Adjustment or the Bonus Accrual and if any such
objections cannot be resolved by Per-Se and Purchaser within thirty (30) days
after receipt by Purchaser of such objections (the notice of which shall also
state with reasonable specificity the reasons for any disagreement and the
amounts in dispute), such dispute will immediately be submitted to the
Accountants for a final and binding resolution of such dispute within thirty
(30) days (the "Determination") and the Determination shall be conclusive and
binding. The fees of such firm incurred in resolving such dispute will be paid
by the party against whom such objections are resolved. Purchaser will, upon
request of Per-Se make available to Per-Se's accountants and to the
Accountants, all work papers prepared in connection with the preparation of the
Closing Balance Sheet, together with reasonable access to the information and
individuals as necessary to determine the accuracy of the Working Capital
Purchase Price Adjustment and the Bonus Accrual.

                           (c)      If, after following the procedures set
forth in Section 1.4(b) above, the Working Capital Purchase Price Adjustment is
a positive number, or if the Estimated Bonus Accrual exceeds the Bonus Accrual,
the amount(s) so determined shall be paid by Purchaser to Seller in immediately
available funds within five (5) days after the earliest to occur of (i) final
approval of the Closing Balance Sheet by Per-Se or agreement between the
Parties on the Working Capital Purchase Price Adjustment or the Bonus Accrual,
(ii) expiration of the Notification Period with no written objections being
received by Purchaser, or (iii) receipt by Purchaser and Per-Se of the
Determination.

                           (d)      If, after following the procedures set
forth in Section 1.4(b) above, the Working Capital Purchase Price Adjustment is
a negative number, or if the Bonus Accrual exceeds the Estimated Bonus Accrual,
the amount(s) so determined shall be paid by Seller to Purchaser in immediately
available funds within five (5) days after the earliest to occur of (i) final
approval of the Closing Balance Sheet by Per-Se or agreement between the
Parties on the Working Capital Purchase Price Adjustment or the Bonus Accrual,
(ii) expiration of the Notification Period with no written objections being
received by Purchaser, or (iii) receipt by Purchaser and Per-Se of the
Determination. Purchaser, at its discretion, may notify the Escrow Agent
pursuant to the terms of the Escrow Agreement of the amount owed to Purchaser
and receive the amount owed to Purchaser hereunder from the Escrow Amount.

                  1.5      Retention of Assets. Purchaser acknowledges and
agrees that it is acquiring the Cash Amount at the Closing (the Cash Amount
shall be equal to actual cash in the Company bank accounts retained by the
Company after Closing), and agrees that the Company may make a distribution at
Closing to Per-Se in an amount equal to all cash on hand of the Company on the
Closing Date in excess of such amount.

                  1.6      Further Assurances. Holdings and Per-Se after the
Closing Date, at Purchaser's request, will execute, acknowledge and deliver to
Purchaser such other instruments of conveyance and transfer and will take such
other actions and execute and deliver such other documents, certifications, and
further assurances as Purchaser may reasonably require in order to vest more
effectively in Purchaser, or to put Purchaser more fully in possession of, any
of the Assets or the Impact Common Stock, or to better enable Purchaser to
complete, perform or discharge the obligations of the Company. Without limiting
the generality of the foregoing, if any party to a Government Contract (other
than the Company itself) requires an assignment or novation Contract be entered
into to continue performance under the Government Contract, the Parties will
cooperate to the fullest extent reasonably practicable, including executing a
novation agreement on terms no less favorable to the U.S. Government as the
terms are reflected in the form novation agreement set forth in 42.12 of the
FAR. Each of the Parties hereto will cooperate with the other and execute and
deliver to the other Parties hereto such other instruments and documents and
take such other actions as may be reasonably requested from time to time by any
other party hereto as necessary to carry out, evidence, and confirm the
intended purposes of this Agreement.

                  1.7      (a)      Notwithstanding the other provisions of the
Agreement to the contrary, Per-Se and Purchaser agree that, prior to the
Closing Date, Per-Se shall cause Company to be converted, by means of a merger
or conversion (collectively, the "Conversion") to a Delaware or Maryland
limited liability company (the "LLC"), all of the membership units and other
economic interests (collectively, the "Units") of which are held by Holdings.
In connection therewith, the Parties agree to take the following actions prior
to the Closing Date:

                           (i)      Per-Se, at its expense, shall cause the
                  Conversion to occur such that all of the Assets and
                  Liabilities of the Company immediately after the Conversion
                  shall be held in the LLC and only such Assets and Liabilities
                  shall be held by the LLC immediately after the Conversion.

                           (ii)     Per-Se shall cause all of the issued and
                  outstanding Shares of the Company to be converted into and
                  exchanged for the Units.

                           (iii)    Per-Se shall cause the LLC to be taxed as a
                  business entity which shall be disregarded as an entity
                  separate from its owner for Tax purposes within the meaning
                  of Treasury Regulation Section 301.7701-3(b)(1)(ii).

                           (iv)     The Parties will execute such documents,
                  certificates and agreements reasonably necessary to carry
                  out the Conversion.

                  (b)      At the Closing, the representations and warranties
set forth in Section 2 of the Agreement as they relate to the Company shall be
restated as provided in Section 6.2(a), except that those representations and
warranties which relate to the Company's corporate status and authority shall
be given by the LLC with respect to the appropriate counterparts of its status
under applicable limited liability company Laws and those representations and
warranties which relate to the effect of the Stock Purchase on circumstances or
documents shall be given by the LLC with respect to the LLC Conversion. In
addition, covenants of Per-Se, Holdings and the Company in the Agreement shall
be conformed and restated to become consistent with the Company's LLC status
and the effect of an LLC Conversion rather than a Stock Purchase. Per-Se shall
cause the LLC to deliver such additional certificates or documents (including
opinions) as shall be reasonably requested by Purchaser to evidence the same.

                  (c)      Purchaser shall prepare a schedule allocating the
Purchase Price (together with all other capitalizable costs) among the Assets
of Impact (the "Allocation Schedule") for Per-Se's review and approval,
provided that Per-Se shall not unreasonably withhold such approval. Such
allocation will comply with the requirements of Section 1060 of the Code.
Purchaser and Per-Se each agrees to file IRS Form 8594, and all federal, state,
local and foreign Tax Returns, in accordance with the Allocation Schedule.
Per-Se agrees to provide promptly to Purchaser any other information required
to complete the Allocation Schedule.


                                   ARTICLE 2
             REPRESENTATIONS AND WARRANTIES OF PER-SE AND HOLDINGS

                  Per-Se and Holdings hereby jointly and severally represent
and warrant to the Purchaser as follows:

                  2.1      Organization, Standing, and Power. Each of Holdings,
Impact and Per-Se is a corporation validly existing and in good standing under

and authority to carry on its business as now conducted and to own, lease and
operate its material Assets. The Company is duly qualified or licensed to
transact business as a foreign corporation in good standing in the States of
the United States and foreign jurisdictions where the character of its Assets
or the nature or conduct of its business requires it to be so qualified or
licensed, except for such jurisdictions in which the failure to be so qualified
or licensed is not reasonably likely to have, individually or in the aggregate,
a Company Material Adverse Effect. The minute book and other organizational
documents for Company have been made available to Purchaser for its review and
are true and complete in all material respects as in effect as of the date of
this Agreement and accurately reflect in all material respects all amendments
thereto and all proceedings of the Board of Directors and shareholders thereof.
The stock record book of the Company, which has been made available for review,
contains true, complete and accurate records of the stock ownership of the
Company and the transfer of the shares of its capital stock. Section 2.1 of the
Company Disclosure Memorandum lists the names of all directors and officers of

pension, retirement, profit-sharing, deferred compensation, stock option,
employee stock ownership, severance pay, vacation, bonus, or other incentive
plan, all other written employee programs, arrangements, or agreements, all
medical, vision, dental, or other health plans, all life insurance plans, and
all other employee benefit plans or fringe benefit plans, including "employee
benefit plans" as that term is defined in Section 3(3) of ERISA, currently
adopted, maintained by, sponsored in whole or in part by, or contributed to by
the Company for the benefit of employees, retirees, dependents, spouses,
directors, independent contractors, or other beneficiaries and under which
employees, retirees, dependents, spouses, directors, independent contractors,
or other beneficiaries are eligible to participate (collectively, the "Company
Benefit Plans") and such related documents and information as the Purchaser may
reasonably request. Any of the Company Benefit Plans which is an "employee
pension benefit plan," as that term is defined in Section 3(2) of ERISA, is
referred to herein as a "Company ERISA Plan." Each Company ERISA Plan which is
also a "defined benefit plan" (as defined in Section 414(j) of the Internal
Revenue Code) is referred to herein as a "Company Pension Plan."

                           (b)      Except as disclosed in Section  2.14(b) of
the Company Disclosure Memorandum, all Company Benefit Plans are in material
compliance with the terms thereof and all applicable terms of ERISA, the
Internal Revenue Code, and any other applicable Laws. Each Company ERISA Plan
which is intended to be qualified under Section 401(a) of the Internal Revenue
Code has received a favorable determination letter from the Internal Revenue
Service, and Company, Seller and Per-Se are not aware of any circumstances
likely to result in revocation of any such favorable determination letter. To
the Knowledge of the Company, Holdings and Per-Se, the Company has not engaged
in a transaction with respect to any Company Benefit Plan that, assuming the
taxable period of such transaction expired as of the date hereof, would subject
the Company to a Tax imposed by either Section 4975 of the Internal Revenue
Code or Section 502(i) of ERISA. Neither the Company nor any ERISA Affiliate of
the Company nor any employee or agent thereof, has made any oral or written
representation to any participant in or beneficiary of a Company Benefit Plan,
or to any other individual or entity that is contrary to the terms of any
Company Benefit Plan.

                           (c)      Neither the Company  nor any entity  which
is considered one employer with the Company under Section 4001 of ERISA or
Section 414 of the Internal Revenue Code of Section 302 of ERISA (whether or
not waived) (an "ERISA Affiliate") maintains or contributes or has maintained
or contributed to a Company Pension Plan that is or was subject to Title IV of
ERISA or Section 412 of the Internal Revenue Code.

                           (d)      Except as disclosed in Section 2.14(d) of
the Company Disclosure Memorandum, to the Knowledge of the Company and Per-Se,
the Company has no Liability for retiree health and life benefits under any of
the Company Benefit Plans and there are no restrictions on the rights of the
Company to amend or terminate any such retiree health or benefit Plan without
incurring any Liability thereunder.

                           (e)      Except as  disclosed  in  Section  2.14(e)
of the Company Disclosure Memorandum, neither the execution and delivery of
this Agreement nor the consummation of the transactions contemplated hereby
will (i) result in any payment (including


                                      13
<PAGE>   17

severance, unemployment compensation, golden parachute, or otherwise) becoming
due to any director or any employee of the Company from the Company under any
Company Benefit Plan or otherwise, (ii) increase any benefits otherwise payable
under any Company Benefit Plan, or (iii) result in any acceleration of the time
of payment or vesting of any such benefit. The Company does not, and will not,
upon consummation of the Stock Purchase have any Liability to anyone for rights
and obligations of any entity under any bonus plan and the Impact Innovations
Key Employee Incentive Plan or under any stock option agreement issued
thereunder.

                           (f)      To the  Knowledge of the Company and Per-Se,
the actuarial present values of all accrued deferred compensation entitlements
(including entitlements under any executive compensation, supplemental
retirement, or employment agreement) of employees and former employees of the
Company and their respective beneficiaries, have been fully reflected on the
Company Financial Statements to the extent required by and in accordance with
GAAP.

                           (g)      To the extent a Company  Benefit  Plan has
excluded any individual from coverage, such exclusion is (i) consistent with
the written terms of the Company Benefit Plan, (ii) enforceable under the terms
of such Plan, (iii) consistent with the terms of any agreement with such
individual (whether written or oral); and (iv) enforceable under applicable
Law.

                           (h)      After the Closing Date,  neither  Purchaser
nor the Company shall have any liability or obligation with respect to any
Company Benefit Plan or any other employee benefit, plan, program, arrangement
or policy that covers employees of the Company, other than those disclosed in
Section 2.14(h) of the Company Disclosure Memorandum. Regardless of whether it
is disclosed in Section 2.14 (h) of the Company Disclosure Memorandum, neither
Purchaser nor Company shall have any liability or obligation with respect to
the Minimum Premium Agreement with Great-West Life & Annuity Insurance Company
that provides benefits pursuant to a plan that covers employees of the Company.
With respect to any Company Benefit Plan under which the Company is not the
sole named insured, neither Purchaser nor the Company shall have any liability
or obligation as to payment of premiums, benefits or other charges that accrue
or are attributable to coverage or claims incurred after the Closing Date,
other than those that are reflected on the Closing Balance Sheet.

                  2.15     Material Contracts. Except as disclosed in Section

Contracts have been provided to, or made available to, Purchaser. With respect
to each Company Contract and except as disclosed in Section 2.15(b) of the
Company Disclosure Memorandum: (i) the Contract is in full force and effect;
(ii) the Company is not in material Default thereunder, nor will the
transactions contemplated hereunder cause a Default; (iii) the Company has not

money borrowed and the Company at Closing will not be liable for any
indebtedness of any Affiliate of the Company.

                  2.16     Legal Proceedings. Except as disclosed on Section
2.16(a) of the Company Disclosure Memorandum, there is no (i) Litigation

Material Adverse Effect, nor are there any Orders of any Regulatory

each of such reports and documents, including the financial statements,
exhibits, and schedules thereto, complied in all material respects with all
applicable Laws. As of its respective date, each such report and document did
not, in all material respects, contain any untrue statement of a material fact

                                   ARTICLE 3
                REPRESENTATIONS AND WARRANTIES OF THE PURCHASER

                  The Purchaser hereby represents and warrants to Holdings and
Per-Se as follows:

                  3.1      Organization, Standing, and Power. Purchaser is a
corporation validly existing, and in good standing under the Laws of the State
of Georgia, and has the corporate power and authority to carry on its business
as now conducted and to own, lease and operate its material Assets. Purchaser
is duly qualified or licensed to transact business as a foreign corporation in
good standing in the States of the United States and foreign jurisdictions
where the character of its Assets or the nature or conduct of its business
requires it to be so qualified or licensed, except for such jurisdictions in
which the failure to be so qualified or licensed is not reasonably likely to
have, individually or in the aggregate, a Purchaser Material Adverse Effect.

                  3.2      Authority; No Breach By Agreement.

                           (a)      Purchaser  has the  corporate  power and
authority to execute and deliver this Agreement and the Closing Documents to
which it is a party and to perform its obligations under this Agreement and the
Closing Documents. The execution, delivery and performance of this Agreement
has been duly authorized by all necessary corporate action on the part of
Purchaser. This Agreement represents a legal, valid, and binding obligation of
Purchaser, enforceable against Purchaser in accordance with its terms (except
in all cases as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, receivership, conservatorship, moratorium, or
similar Laws affecting the enforcement of creditors' rights generally and
except that the availability of the equitable remedy of specific performance or


                                      17
<PAGE>   21

injunctive relief is subject to the discretion of the court before which any
proceeding may be brought). Upon the execution and delivery of the Closing
Documents to which it is a party, such Closing Documents will constitute the
legal, valid and binding obligations of Purchaser, enforceable against
Purchaser in accordance with their respective terms.

                           (b)      Neither  the  execution  and  delivery  of
this Agreement by Purchaser, nor the consummation by Purchaser of the
transactions contemplated hereby, nor compliance by Purchaser with any of the
provisions hereof, will (i) conflict with or result in a breach of any
provision of Purchaser's Articles of Incorporation or Bylaws, or (ii) except as
disclosed in Section 3.2 of the Purchaser Disclosure Memorandum constitute or
result in a Default under, or require any Consent pursuant to, or result in the
creation of any Lien on any Asset of Purchaser under, any Contract or Permit,
or, (iii) subject to receipt of the requisite Consents referred to in Section
6.2(c), constitute or result in a Default under, or require any Consent
pursuant to, any Law or Order applicable to Purchaser or any of its material
Assets.

                           (c)      Other than in connection or compliance
with the provisions of the Securities Laws, applicable state corporate and
securities Laws, and other than: (i) Consents required from Regulatory
Authorities; (ii) notices to or filings with the Internal Revenue Service or
the Pension Benefit Guaranty Corporation with respect to any employee benefit
plans; and (iii) filings under the HSR Act; no notice to, filing with, or
Consent of, any public body or authority is necessary for the consummation by
Purchaser of the transactions contemplated in this Agreement.

                  3.3      Compliance with Laws. Purchaser has in effect all
Permits necessary for it to own, lease or operate its material Assets and to
carry on its business as now conducted. Except as disclosed in Section 3.3 of
the Purchaser Disclosure Memorandum, Purchaser is not:

                           (a)      in  Default  under  any  of  the
provisions of its Articles or Certificate of Incorporation or Bylaws (or other
governing instruments);

                           (b)      in  Default  under any Laws,  Orders,  or
Permits applicable to its business or employees conducting its business; or

                           (c)      since  January 1, 1994, in receipt of any
notification or communication from any agency or department of federal, state,
or local government or any Regulatory Authority or the staff thereof (i)
asserting that Purchaser is not in compliance with any of the Laws or Orders
which such governmental authority or Regulatory Authority enforces, (ii)
threatening to revoke any Permits, or (iii) requiring Purchaser to enter into
or consent to the issuance of a cease and desist order, formal agreement,
directive, commitment or memorandum of understanding, or to adopt any Board
resolution or similar undertaking.

                  3.4      Legal Proceedings. There is no Litigation instituted
or pending, or, to the Knowledge of Purchaser, threatened (or unasserted but
considered probable of assertion and which if asserted would have at least a
reasonable probability of an unfavorable outcome) against Purchaser, or against
any director, employee or employee benefit plan of Purchaser, nor are there any
Orders of any Regulatory Authorities, other governmental authorities, or
arbitrators outstanding against Purchaser.

                  3.5      Investment Intent. The Purchaser is acquiring the
Shares for its own account and not with a view to their distribution within the
meaning of Section 2(11) of the Securities Act of 1933, as amended. The
Purchaser confirms that Per-Se, Holdings and the Company have made available to
the Purchaser and its representatives and agents the opportunity


                                      18
<PAGE>   22

to ask questions of the officers and management employees of the Company and to
acquire such additional information about the business and financial condition
of the Company as the Purchaser has requested.

                           (i)      adopt any new employee  benefit  plan of
the Company or terminate or withdraw from, or make any material change in or
to, any existing employee benefit plans of the Company other than any such
change that is required by Law or that, in the opinion of counsel, is necessary
or advisable to maintain the tax qualified status of any such plan, or make any
distributions from such employee benefit plans, except as required by Law, the
terms of such plans or consistent with past practice; or

                           (j)      make any significant  change in any Tax

be appropriate to conform to changes in Tax Laws or regulatory accounting

compromise or assign any material rights or claims; or

                           (m)      make any  capital  expenditure  involving

Agreement until the earlier of the Closing Date or the termination of this
Agreement, unless the prior written consent of Holdings or Per-Se shall have

adversely affect the ability of any Party to obtain any Consents required for
the transactions contemplated


                                      20
<PAGE>   24

hereby without imposition of a condition or restriction of the type referred to
in the last sentences of Section 6.1(a) or 6.2(c), or (ii) adversely affect the
ability of any Party to perform its covenants and agreements under this
Agreement; provided, that the foregoing shall not prevent Purchaser from
discontinuing or disposing of any of its Assets or business if such action is,
in the judgement of Purchaser, desirable in the conduct of the business of
Purchaser and its Subsidiaries.

                  4.4      Adverse Changes in Condition. Each Party agrees to
give written notice promptly to the other Party upon becoming aware of the
occurrence or impending occurrence of any event or circumstance relating to it
or any of its Subsidiaries which (i) is reasonably likely to have, individually
or in the aggregate, a Company Material Adverse Effect or a Purchaser Material
Adverse Effect, as applicable, or (ii) would cause or constitute a material
breach of any of its representations, warranties, or covenants contained
herein, and to use its reasonable efforts to prevent or promptly to remedy the
same.

                  4.5      Reports. Each Party shall file all reports required
to be filed by it with Regulatory Authorities between the date of this
Agreement and the Closing Date and shall deliver to the other Party copies of
all such reports promptly after the same are filed. Any financial statements
contained in any reports to a Regulatory Authority shall be prepared in
accordance with Laws applicable to such reports.

                  4.6      Related Party Transactions. Per-Se, Impact and

                  5.1      Applications; Antitrust Notification. The Purchaser
shall promptly prepare and file, and Per-Se and Holdings shall cooperate in the
preparation and, where appropriate, filing of, applications with all Regulatory
Authorities having jurisdiction over the transactions contemplated by this
Agreement seeking the requisite Consents necessary to consummate the
transactions contemplated by this Agreement. To the extent required by the HSR
Act, each of the Parties will promptly file with the United States Federal
Trade Commission and the United States Department of Justice the notification
and report form required for the transactions contemplated hereby and any
supplemental or additional information which may reasonably be requested in
connection therewith pursuant to the HSR Act and will comply in all material
respects with the requirements of the HSR Act. The Parties shall deliver to
each other copies of all filings, correspondence and orders to and from all
Regulatory Authorities in connection with the transactions contemplated hereby.

                  5.2      Agreement as to Efforts to Consummate. Subject to the
terms and conditions of this Agreement, each Party agrees to use its reasonable
efforts to take, or cause to be taken, all actions, and to do, or cause to be
done, all things necessary, proper, or advisable under applicable Laws to
consummate and make effective, as soon as reasonably practicable after the date
of this Agreement, the transactions contemplated by this Agreement, including
using its reasonable efforts to lift or rescind any Order adversely affecting
its ability to consummate the transactions contemplated herein and to cause to
be satisfied the conditions referred to in Article


                                      21
<PAGE>   25

6; provided, that nothing herein shall preclude either Party from exercising
its rights under this Agreement. Each Party shall use its reasonable efforts to
obtain all Consents necessary or desirable for the consummation of the
transactions contemplated by this Agreement.

                  5.3      Investigation and Confidentiality.

                           (a)      Prior to the Closing  Date,  the  Company
shall keep the Purchaser advised of all material developments relevant to its
business and to consummation of the Stock Purchase and shall permit Purchaser
to make or cause to be made such investigation of the business and properties
of Company and of their respective financial and legal conditions as Purchaser
reasonably requests, provided that such investigation shall be reasonably
related to the transactions contemplated hereby and shall not interfere
unnecessarily with normal operations. No investigation by a Party shall affect
the representations and warranties of the other Party.

                           (b)      The  Purchaser  shall,  and shall cause its
advisers and agents to, maintain the confidentiality of all confidential
information furnished to it by Company concerning Company and its businesses,
operations, and financial positions and shall not use such information for any
purpose except in furtherance of the transactions contemplated by this
Agreement. If this Agreement is terminated prior to the Closing Date, Purchaser
shall promptly return or certify the destruction of all documents and copies
thereof, and all work papers containing confidential information received from
Company.

                           (c)      Per-Se and its  Affiliates  shall use their
reasonable efforts to exercise their rights under confidentiality agreements
entered into with Persons which were considering a transaction with respect to
Company to preserve the confidentiality of the information relating to the
Company provided to such Persons and their Affiliates and Representatives.

                           (d)      Each Party  agrees to give the other Party
notice as soon as practicable after any determination by it of any fact or
occurrence relating to the other Party which it has discovered through the
course of its investigation and which represents, or is reasonably likely to
represent, either a material breach of any representation, warranty, covenant
or agreement of the other Party or which has had or is reasonably likely to
have a Company Material Adverse Effect or a Purchaser Material Adverse Effect,
as applicable; provided, however, that the failure to give such notice shall
not give rise to any Liability against the Party or otherwise affect the
representations, warranties, covenants or agreements of the Parties set forth
herein (or the rights and remedies of the Party in the event of a breach
thereof) or any of the other terms and conditions of this Agreement.

                  5.4      Press Releases. Prior to the Closing Date, Per-Se and
Purchaser shall consult with each other as to the form and substance of any
press release or other public disclosure materially related to this Agreement
or any other transaction contemplated hereby; provided, that nothing in this
Section 5.4 shall be deemed to prohibit any Party from making any disclosure
which its counsel deems necessary or advisable in order to satisfy such Party's
disclosure obligations imposed by Law.

                  5.5      Certain Actions. Except with respect to this
Agreement and the transactions contemplated hereby, no Company Entity nor any
shareholder nor any Affiliate thereof nor any Representatives thereof retained
by Per-Se or Company shall directly or indirectly solicit any Acquisition
Proposal by any Person. No Company Entity, any shareholder or any Affiliate or
Representative thereof shall furnish any non-public information that it is not
legally


                                      22
<PAGE>   26

obligated to furnish, negotiate with respect to, or enter into any Contract
with respect to, any Acquisition Proposal, but Per-Se, Holdings or the Company
may communicate information about such an Acquisition Proposal to its
shareholders if and to the extent that it is required to do so in order to
comply with its legal obligations as advised by outside counsel.

                  5.6      Tax Matters.

                           (a)      Cooperation and Exchange of Information.
Per-Se and the Purchaser will provide each other with such cooperation and
information as any of them reasonably may request of the other in filing any
Tax Return, amended return or claim for refund, determining a Liability for
Taxes or a right to a refund of Taxes or participating in or conducting any
audit or other proceeding in respect of Taxes. Such cooperation and information
shall include providing copies of relevant Tax Returns or portions thereof,
together with accompanying schedules and related work papers and documents
relating to rulings or other determinations by Tax authorities, but in no event
shall Per-Se or the Purchaser be required to disclose to the other any
information relating to the operations of either, as the case may be, other
than information relating to a Liability for Taxes of the Company. Per-Se and
the Purchaser shall make their respective employees available on a mutually
convenient basis to provide explanations of any documents or information
provided hereunder. Per-Se and Holdings will take no position on such Tax
Returns that relate to the Company that would adversely affect the Company
after the Closing Date, unless such position would be reasonable and consistent
with past practice as if Per-Se or Holdings had owned the Company both before
and after the Closing Date. Per-Se and the Purchaser will retain all Tax
Returns, schedules and work papers and all material books and records or other
documents relating to Tax matters of the Company for its taxable period ending
on or before the Closing Date until the expiration of the statute of
limitations of the taxable periods to which such returns and other documents
relate, without regard to extensions (but taking into account any extended
statute of limitations applicable to a year in which a net operating loss is
reported) except to the extent notified by the other party in writing of such
extensions for the respective Tax periods. Any information obtained under this
Section 5.6(a) shall be kept confidential, except as may be otherwise necessary
in connection with the filing of returns or claims for refund or in conducting
an audit or other proceeding. Notwithstanding anything in this Section 5.6(a)
to the contrary, no party shall be required to divulge any information to the
other party that would operate as a waiver of the attorney-client privilege.
Purchasers and the Seller shall use reasonable efforts not to destroy or allow
the destruction of any such books and records and workpapers without first
providing 60 days written notice of intention to destroy to the other
party(ies), and allowing such other party(ies) to take possession of such
records.

                           (b)      Tax  Indemnification.  Notwithstanding  any
provision of this Agreement to the contrary, Per-Se and Holdings shall be
jointly and severally liable, and shall pay, indemnify, and hold harmless
(including any Tax owed by the Purchaser as a result of this indemnification
payment) the Purchaser and the Company for (i) all Liability for Taxes of the
Company (including Taxes owed by Purchaser as a result of such indemnification
payment), for all periods or portions thereof ending on or prior to the Closing
Date; (ii) all Liability for Taxes of any affiliated, consolidated, unitary or
combined group or any member thereof, which affiliated, consolidated, unitary
or combined group includes or has included the Company for any period or
portion thereof ending on or prior to the Closing Date; and (iii) all Liability
for Taxes of the Company for all taxable periods beginning before the Closing
Date and ending after such date but only with respect to the portion of such
period ending on the Closing Date. Any Taxes under (iii) for a period
commencing prior to but ending after the Closing Date will be apportioned, in
the case of real and personal property Taxes, on a per diem basis and, in the
case of other Taxes, on


                                      23
<PAGE>   27

the basis of the actual activities, taxable income or taxable loss of the
Company during the periods before and after the Closing Date, based upon a
closing of the books and determined as if such period ended with respect to
Per-Se on the Closing Date and commenced with respect to the Purchaser on the
date after the Closing Date. The Purchaser agrees to indemnify Per-Se for any
additional Tax owed by Per-Se (including Tax owed by Per-Se due to this
indemnification payment) resulting from any transaction initiated by Purchaser
and not in the ordinary course of business occurring on the date of this
Agreement. The Purchaser and Per-Se agree to report all transactions initiated
by the Purchaser and not in the ordinary course of business occurring on the
date of this Agreement on the Purchaser's federal income Tax Return to the
extent permitted by Section 1.1502-76(b)(1)(ii)(B) of the Treasury Regulations
promulgated pursuant to the Code. Any refund of Taxes received, or reduction of
Taxes realized by Per-Se, or any Affiliate of Per-Se, that is directly
attributable to Taxes paid or losses or credits generated by the Company with
respect to any period or portion thereof ending after the Closing Date is to be
paid to Purchaser within thirty (30) days after the receipt or credit thereof.
Per-Se and Holdings shall comply with Purchaser's requests in obtaining such
refunds, including, but not limited to, the filing of amended returns and
claims for refund. Any refund of Taxes received by the Purchaser, or any
Affiliate of Purchaser, that is directly attributable to Taxes paid by the
Company with respect to any period or portion thereof ending on or before the
Closing Date is to be paid to Per-Se within thirty (30) days after the receipt
or credit thereof. The Purchaser shall comply with Per-Se's requests in
obtaining such refunds, including, but not limited to, the filing of amended
returns and claims for refund.

                  5.7      Government Contract Audits. Purchaser shall give
notice to Per-Se of any notice Purchaser or the Company receives of any
scheduled audits requested by the Defense Contract Audit Agency related to
services provided prior to Closing under existing Government Contracts. Per-Se
shall have the right to observe the audit process and review the results.
Purchaser agrees to cause the Company to act reasonably and in good faith to
mitigate the adverse consequences to any Party resulting from such an audit.

                  5.8      Employee Benefits and Contracts.

                           (a)      Following the Closing Date,  the Purchaser
shall provide generally to officers and employees of the Company employee
benefits under employee benefit and welfare plans (other than stock option or
other plans involving the potential issuance of Purchaser Common Stock), on
terms and conditions which when taken as a whole are substantially similar to
those currently provided by the Purchaser to its similarly situated officers
and employees. For purposes of participation, to the extent permitted under
Purchaser's employee benefit plans, vesting and (except in the case of
Purchaser retirement plans) benefit accrual under Purchaser's employee benefit
plans, the service of the employees of the Company prior to the Closing Date
shall be treated as service with Purchaser for purposes of participating in
such employee benefit plans. Purchaser agrees that expenses incurred by
employees of the Company with respect to Company health plans for the current
year shall be credited for purposes of satisfying health plans for the current
year. Per-Se shall cause Per-Se or Holdings to honor in accordance with their
terms all employment, severance, consulting and other compensation Contracts
disclosed in Section 5.8(a) of the Company Disclosure Memorandum to Purchaser
between Holdings or Per-Se and any current or former director, officer, or
employee thereof. Until such Plans are amended by the Company, Purchaser shall
cause the Company to honor all provisions for benefits or other amounts earned
or accrued through the Closing Date under the Company Benefit Plans retained by
the Company in accordance with the terms of such Company Benefit Plans. Any
retention agreements or change in control agreements shall be fulfilled or


                                      24
<PAGE>   28

paid out by Holdings or Per-Se at Closing if the Stock Purchase triggers any
event under any such agreement.

                           (b)      Seller or  Holdings  shall make  401(k)
distributions to the Company's employees pursuant to Section
1.401(k)-1(d)(1)(v) of the Code.

                  5.9      Insurance. To the extent the Company suffers a Loss
the circumstances for which are covered by insurance retained by Per-Se, Per-Se
agrees to make a claim and seek insurance proceeds for the benefit of the
Company. All such insurance proceeds (regardless of whether Purchaser has
indemnification rights related to the Loss) actually received by Per-Se shall
be promptly remitted to the Company less any applicable deductible and less
actual costs incurred out-of-pocket by Per-Se to obtain the proceeds.

                  5.10     Bonus Payment. Purchaser shall cause the Company to
pay Company employees amounts due under the Target Performance Bonus Program in
accordance with the terms of such Bonus Program. If, on the date the bonuses
are due to the Company employees, the amount payable under the Bonus Program on
which the Bonus Accrual was calculated is determined to be greater than the
amount actually paid pursuant to the terms of the Bonus Program, and if such
determination has not been reflected in the adjustments to the Purchase Price
as set forth in Sections 1.3 or 1.4 hereof, Purchaser shall cause the excess to
be paid to Per-Se or Holdings within five (5) days of such determination.

                  5.11     Holdings Options. Per-Se or Holdings will cash out
within 45 days of Closing all outstanding stock options granted pursuant to the
Impact Innovations Key Employee Incentive Plan (the "Holdings Stock Plan") and
Per-Se will use its best efforts to cause the options holders to release the
Parties and acknowledge the cancellation or termination of the stock option
agreements related thereto.

                  5.12     Supplemental Disclosure. The Parties shall have the
continuing obligation up to and including the Closing Date to supplement
promptly or amend the Company Disclosure Memorandum or the Purchaser Disclosure
Memorandum as applicable, with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would
have been required to be set forth or listed in the applicable Disclosure
Memorandum; provided, however, that for the purpose of the rights and
obligations of the Parties hereunder, any such supplemental disclosure shall
not be deemed to have been disclosed as of the date of this Agreement unless so
agreed to in writing by Purchaser. Purchaser's remedy for supplemental
disclosures to which it does not agree to in writing shall be to terminate the
Agreement pursuant to Section 8.1(c) hereof.

                                   ARTICLE 6
               CONDITIONS PRECEDENT TO OBLIGATIONS TO CONSUMMATE

                  6.1      Conditions to Obligations of Each Party. The
respective obligations of each Party to perform this Agreement and consummate
the Stock Purchase and the other transactions contemplated hereby are subject
to the satisfaction of the following conditions, unless waived by both Parties
pursuant to Section 9.6:

                           (a)      Regulatory  Approvals.   All  Consents  of,
filings and registrations with, and notifications to, all Regulatory
Authorities required for consummation of the Stock Purchase shall have been
obtained or made and shall be in full force and effect and all waiting periods
required by Law shall have expired or been terminated. No Consent obtained from
any


                                      25
<PAGE>   29

Regulatory Authority which is necessary to consummate the transactions
contemplated hereby, shall be conditioned or restricted in a manner (including
requirements relating to the raising of additional capital or the disposition
of Assets) which in the reasonable judgment of the Board of Directors of
Purchaser and Holdings would so materially adversely impact the economic or
business benefits of the transactions contemplated by this Agreement that, had
such condition or requirement been known, such Party would not, in its
reasonable judgment, have entered into this Agreement.

                           (b)      Legal  Proceedings.  No court or
governmental or regulatory authority of competent jurisdiction shall have
enacted, issued, promulgated, enforced or entered any Law or Order (whether
temporary, preliminary or permanent) or taken any other action which prohibits,
restricts or makes illegal consummation of the transactions contemplated by
this Agreement.

                  6.2      Conditions to Obligations of the Purchaser. The
obligations of the Purchaser to perform this Agreement and consummate the Stock
Purchase and the other transactions contemplated hereby are subject to the
satisfaction of the following conditions, unless waived by the Purchaser
pursuant to Section 9.6(a):

                           (a)      Representations  and Warranties.  For
purposes of this Section 6.2(a), the accuracy of the representations and
warranties of Per-Se and Holdings set forth in this Agreement shall be true and
correct in all material respects as of the date of this Agreement and as of the
Closing Date with the same effect as though all such representations and
warranties had been made on and as of the Closing Date (provided that
representations and warranties which are confined to a specified date shall
speak only as of such date). There shall not exist inaccuracies in the
representations and warranties of Per-Se and Holdings set forth in this
Agreement such that the aggregate effect of such inaccuracies has, or is
reasonably likely to have, a Company Material Adverse Effect; provided that,
for purposes of this sentence only, those representations and warranties which
are qualified by references to "material" or "Material Adverse Effect" or to
the "Knowledge" of any Person shall be deemed not to include such
qualifications.

                           (b)      Performance  of  Agreements  and  Covenants.
Each and all of the agreements and covenants of Per-Se, Holdings and the
Company to be performed and complied with pursuant to this Agreement and the
other agreements contemplated hereby prior to the Closing Date shall have been
duly performed and complied with.

                           (c)      Consents  and  Approvals.  Each  Party
shall have obtained any and all Consents reasonably deemed by Purchaser to be
required for consummation of the Stock Purchase or to continue the benefits to
Company under such Contracts, or for the preventing of any Default under any
Company Contract or Permit of such Party, including Consents for the Company
Contracts or Permits listed in Section 6.2(c) of the Company Disclosure
Memorandum. No such Consent so obtained which is necessary to consummate the
transactions contemplated hereby, shall be conditioned or restricted in a
manner (including requirements relating to the raising of additional capital or
the disposition of Assets) which in the reasonable judgment of the Board of
Directors of Purchaser and Holdings would so materially adversely impact the
economic or business benefits of the transactions contemplated by this
Agreement that, had such condition or requirement been known, such Party would
not, in its reasonable judgment, have entered into this Agreement.

                           (d)      Certificates.  Per-Se shall have delivered
to the Purchaser (i) a certificate, dated as of the Closing Date, and signed on
its behalf by duly authorized officers, to


                                      26
<PAGE>   30

the effect that the conditions set forth in Section 6.1 as relates to Per-Se
and in Sections 6.2(a), 6.2(b) and 6.2(c) have been satisfied, all in such
reasonable detail as the Purchaser and its counsel shall request and (ii)
certified copies of Articles or Certificate(s) of Incorporation or other
formation documents of Holdings and Impact, certified bylaws of Holdings and
Impact and resolutions duly adopted by Per-Se and Holdings' Board of Directors
and, if applicable, shareholders, evidencing the taking of all corporate action
necessary to authorize the execution, delivery and performance of this
Agreement, and the consummation of the transactions contemplated hereby, all in
such reasonable detail as the Purchaser shall request.

                           (e)      Opinion of  Counsel.  Purchaser  shall  have
received from Randolph L.M. Hutto, General Counsel for Seller, an opinion dated
the Closing Date, in form reasonably satisfactory to Purchaser.

                           (f)      Net Working  Capital.  The Net Working
Capital as of the Closing shall not be less than $8,000,000. Cash at Closing
shall not be less than the Cash Amount.

                           (g)      Satisfactory  Instruments.  All  instruments
of conveyance and transfer required on the Company's or Per-Se's part to
effectuate and consummate the transactions contemplated hereby will be
delivered to Purchaser and will be in form and substance reasonably
satisfactory to Purchaser and its counsel. Purchaser shall have received
evidence satisfactory to it that all Liens against the Assets of the Company
have been released or terminated prior to or at Closing. The officers and
directors of the Company shall have resigned as of the Closing Date, effective
upon consummation of the Stock Purchase.

                           (h)      Litigation.  No Order of any court or
administrative agency will be in effect which enjoins or prohibits the
transactions contemplated hereby or which would materially adversely affect the
Company or the business of the Company, and there will not have been
threatened, nor will there be pending, any action or proceeding by or before
any Regulatory Authority (i) challenging any of the transactions contemplated
by this Agreement or seeking monetary relief by reason of the consummation of
such transactions or (ii) which, if resolved against the Company on its terms,
would reasonably be expected to have a Company Material Adverse Effect on the
future conduct of the business of the Company, taking into account the
magnitude and likelihood of exposure.

                           (i)      No Material  Adverse  Effect;  Condition
of Assets. As of Closing, there will not have occurred any Company Material
Adverse Effect, or any condition or event which is reasonably likely to result
in a Company Material Adverse Effect.

Transition Services Agreement. Per-Se and Holdings shall have entered into,

                           (m)      Assignment  Documents.  Holdings shall have

such that the aggregate effect of such inaccuracies has, or is reasonably
likely to have, a Purchaser Material Adverse Effect; provided that, for
purposes of this sentence only, those representations and warranties which are
qualified by references to "material" or "Material Adverse Effect" or to the
"Knowledge" of any Person shall be deemed not to include such qualifications.

                           (b)      Performance  of  Agreements  and  Covenants.
Each and all of the agreements and covenants of the Purchaser to be performed

6.3(b) have been satisfied, all in such reasonable detail as the Seller and its
counsel shall request, and (ii) certified copies of resolutions duly adopted by
the Purchaser's Board of Directors evidencing the taking of all corporate
action necessary to authorize the execution, delivery and performance of this

                                   ARTICLE 7
                                INDEMNIFICATION

                  7.1      Indemnification of Purchaser. Subject to the terms
and conditions in this Article 7, Per-Se and Holdings shall jointly and
severally indemnify, defend and hold harmless the Purchaser, and its officers,
directors, shareholders, controlling persons, Affiliates and Representatives,
from and against any Losses (but excluding consequential and incidental damages
of Purchaser), suffered or incurred by the Purchaser, as and when incurred, by
reason of, or arising out of, (i) any misrepresentation, breach of warranty or
breach or non-fulfillment of any agreement of Per-Se, Holdings or the Company
contained in this Agreement (except for a misrepresentation or breach of
warranty found in Section 2.21) or in any document executed and


                                      28
<PAGE>   32

delivered in connection with this Agreement, and for purposes of this Section
7.1 any qualification of such representations and warranties by reference to
the materiality of matters having or not having a "Material Adverse Effect,"
and any limitation of such representations and warranties as being "to the
Knowledge of" or "Known to" or words of similar effect, shall be disregarded in
determining any inaccuracy, untruth, incompleteness or each thereof; (ii) the
breach or nonfulfillment of any covenant or agreement of the Seller contained
in this Agreement or in the Closing Documents; (iii) the sale of E-Business
Solutions.com, Inc. by Holdings to Complete Business Solutions, Inc. and the
Rose Budd Lawsuit (iv) the Retention Agreements for Company employees that
Purchaser has notified Per-Se it will not employ post-Closing, Liabilities
arising prior to the Closing for benefits or other charges under the Minimum
Premium Agreement with Great-West Life & Annuity Insurance, any stock option
plan or grants of the Company or any Affiliate of Holdings or Per-Se, including
the Holdings Stock Plan (and any stock options issued thereunder), or any
operational defects in the frozen Rapid Systems Solutions, Inc. 401(k) Plan,
(v) any misrepresentation or breach of warranty of Per-Se or Holdings contained
in Section 2.21 of this Agreement, or Losses arising from any audit performed
post-Closing in respect of the performance of any Government Contract occurring
prior to the Closing Date.

                  7.2      Indemnification of Seller. Subject to the terms and
conditions in this Article 7, the Purchaser shall indemnify, defend and hold
harmless Per-Se, and its respective officers, directors, shareholders,
controlling persons, Affiliates and Representatives, from and against any
Losses (but excluding consequential and incidental damages of Per-Se) suffered
or incurred by Per-Se, as and when incurred, by reason of, or arising out of,
(i) any misrepresentation, breach of warranty or breach or non-fulfillment of
any agreement of the Purchaser contained in this Agreement or in any document
executed and delivered in connection with this Agreement, and (ii) the breach
or nonfulfillment of any covenant or agreement of the Purchaser contained in
this Agreement or in the Closing Documents.

                  7.3      Notice and Opportunity to Defend. The party
indemnified hereunder (the "Indemnified Party") shall notify in writing the
indemnifying party (the "Indemnifying Party") within thirty (30) days after a
third party claim is presented to the Indemnified Party and the Indemnifying
Party shall defend such claim at its expense and may select the attorneys for
such defense, who shall be reasonably acceptable to the Indemnified Party. If
the Indemnifying Party does not defend such claim, the Indemnified Party may do
so without the Indemnifying Party's participation, in which case the
Indemnifying Party shall pay the expenses of such defense. Neither the
Indemnified Party nor the Indemnifying Party may settle or compromise such
claim without the other party's consent, which shall not be unreasonably
withheld. If the Indemnified Party fails to notify the Indemnifying Party of a
third party claim as provided in this Section 7.3, and if the Indemnifying
Party is thereby prejudiced by such failure of notice in its defense of the
claim, the Indemnifying Party's obligation of indemnity hereunder shall be
extinguished with respect to such claim to the extent that the Indemnifying
Party has been prejudiced by the failure to give such notice. The Indemnified
Party and Indemnifying Party agree to cooperate in good faith in the defense
and/or settlement of any such claim.

                  7.4      Limitations.

                           (a)      A party  otherwise  entitled  to
indemnification under Section 7.1(i) or (ii) or Section 7.2 is not entitled to
indemnification until the aggregate indemnifiable Losses for which it is
otherwise entitled to indemnification hereunder shall equal or exceed U.S.
$500,000 (the "Threshold Amount"). A party otherwise entitled to
indemnification under Sections 7.1(v) is not entitled to indemnification until
the aggregate indemnifiable Losses for


                                      29
<PAGE>   33

which it is otherwise entitled to indemnification hereunder shall equal or
exceed U.S. $250,000 (the "Government Contract Threshold Amount"). The
Threshold Amount and Government Contract Threshold Amount limitations set forth
in this Section shall not apply to any intentional misrepresentation or breach
of warranty of any indemnitor or any intentional failure to perform or comply
with any covenant or agreement of any indemnitor, or to indemnifications rights
provided in Sections 7.1(iii), (iv), or to any Tax Liability of the Company
related to periods ended on or prior to the Closing Date, including the
indemnification provided in Section 5.6(b); and the indemnitors shall be liable
for all Losses with respect thereto. With respect to Sections 7.1(i) or (ii) or
Section 7.2 described above, if and when the sum of all indemnifiable Losses of
a party hereunder equals or exceeds the Threshold Amount, then such party may
request indemnification for all indemnifiable Losses in excess of the Threshold
Amount. With respect to Sections 7.1(v)described above, if and when the sum of
all indemnifiable Losses of a party thereunder equals or exceeds the Government
Contract Threshold Amount, then such party may request indemnification for all
indemnifiable Losses in excess of the Government Contract Threshold Amount, and
the Government Contract Threshold Amount shall be counted towards the Threshold
Amount. To the extent covered by insurance, any indemnifiable Loss will be
deemed reduced by the amount of insurance proceeds actually received by the
Indemnified Party and its Affiliates in respect of such Loss; provided,
however, that in no event shall this sentence be deemed to require any
Indemnified Party to maintain any level of insurance. In no event shall a
party's collective Liability under this Article 7 exceed $6,750,000, except for
Liabilities related to Taxes or matters for which Purchaser is entitled to
indemnification under Sections 7.1(iii) and (iv) (the "Maximum Liability").

                           (b)      The  indemnitors  will have no  liability
to the Indemnified Parties under or in connection with: (a) a breach of any of
the representations, warranties, covenants, or agreements made or to be
performed by the indemnitors contained in this Agreement (other than the
representations and warranties set forth in Sections 2.2, 2.8, 2.9, 2.11, 2.14
and 2.21), unless written notice asserting an Indemnification Claim based
thereon is given to Per-Se or Purchaser, as applicable, prior to the later of
(i) September 30, 2001 or (ii) the first anniversary of the date on which such
covenant or agreement is to be performed hereunder; (b) a breach of any of the
representations, warranties, indemnities, covenants or agreements made or to be
performed by the indemnitors contained in this Agreement related to the
Government Contracts, including without limitation, those representations,
warranties, indemnities, covenants or agreements made by the indemnitors in
Section 7.1(v), unless written notice asserting an Indemnification Claim based
thereon is given to Per-Se on or prior to December 31, 2002; (c) a breach of
any representation, warranty, covenant or agreement made or to be performed by
the indemnitors contained in this Agreement related to any Taxes or employee
benefit plans, including without limitation, those representations and
warranties made by the indemnitors in Sections 2.8 and 2.14, unless written
notice asserting an Indemnification Claim based thereon is given to Per-Se or
Purchaser, as applicable, prior to the later of (i) ninetieth (90th) day after
the date upon which the liability to which any such claim may relate is barred
by all applicable statutes of limitation and (ii) the ninetieth (90th) day
after the date upon which any claim for refund or credit related to such claim
is barred by all applicable statutes of limitation; (d) a breach of any
representation, warranty, covenant or agreement made or to be performed by the
indemnitor contained in this Agreement related to any environmental matters,
including without limitation, those representations and warranties made by the
indemnitor in Section 2.11, unless written notice asserting an indemnification
claim based thereon is given to the Seller or Purchaser, as applicable, prior
to two years from the date hereof; provided, however, the liability of the
indemnitors relating to, arising out of or based upon those representations and
warranties of the indemnitors set forth in Section 2.2(a) and (b)(i) and the
first sentence of 2.9(a) may be asserted at any time.

                  7.5      Survival of Representations and Warranties. The
representations, warranties, covenants and agreements of Per-Se, the Company
and Purchaser will survive the Closing and shall not be deemed waived or
otherwise affected by any investigation conducted with respect thereto.

                  7.6      Subrogation. Upon payment in full of any claim by a
third party under this Article 7 (irrespective of the method of payment), the
Indemnifying Party shall be subrogated to the extent of such payment to the
rights of the Indemnified Party against any Person with respect to the subject
matter of such claim.

                  7.7      Exclusive Remedy. Except for remedies reflected in
the Agreement related to adjustments to the Purchase Price and remedies based
upon fraud, the remedies provided for in this Article 7 constitute the sole and
exclusive remedies for recovery against Per-Se or the Purchaser based upon the
inaccuracy, untruth, incompleteness or breach of any representation or warranty
of such party contained in this Agreement or in any document executed and
delivered in connection with this Agreement, or based upon the failure of
Per-Se, Holdings, the Company or the Purchaser to perform any covenant,
agreement or undertaking required by the terms hereof to be performed by such
party.

                  7.8      Dispute Resolution.

                           (a)      If an Indemnified Party incurs any Loss
indemnifiable under this Article 7("Indemnifiable Loss"), it shall promptly
provide written notice to the Indemnifying Party stating in reasonable detail
the nature and amount of such Indemnifiable Loss or potential Indemnifiable
Loss (a "Loss Notice"). In addition, with respect to third party claims, the
Indemnified Party shall comply with Section 7.3. If the Indemnifying Party
disputes the amount sought under any such Loss Notice or otherwise disputes the
right of the Indemnified Party to be indemnified hereunder, it shall provide
the Indemnified Party a written notice objecting to such claim for
indemnification within thirty (30) days of the date any such Loss Notice is
received by the Indemnifying Party (a "Protest Notice").

                           (b)      If  (i) the  Indemnifying  Party and the
Indemnified Party are unable to resolve a Loss Notice with respect to which the
Indemnified Party has received a Protest Notice (a "Disputed Loss Notice")
within thirty days of the date the Indemnified Party receives the Protest
Notice, or (ii) there is any other controversy or claim arising out of or
relating to this Agreement or a breach hereof, then any of the parties hereto
may require such Disputed Loss Notice or other controversy or claim to be
submitted to arbitration in the venue of Atlanta, Georgia in accordance with
the then-current expedited procedures of the commercial arbitration rules of
the American Arbitration Association ("AAA"). In any arbitration hereunder, the
Purchaser shall select one arbitrator, Per-Se shall select one arbitrator, and
the two arbitrators so chosen shall select a third. All such arbitrators must
be selected from the list of arbitrators maintained by the AAA. Any decision of
the arbitration panel shall require the vote of at least two (2) of such
arbitrators and shall be deemed conclusive and each party shall be deemed to
have waived any rights to appeal therefrom. Each party shall bear its own legal
fees and related expenses incurred in connection with the arbitration
proceedings.

                  7.9      Escrow. Upon notice to Per-Se specifying in
reasonable detail the basis therefor, Purchaser may give notice of an
Indemnification Claim under the Escrow Agreement until September 30, 2001.
Neither the exercise of, nor the failure to exercise such right to give a
notice of an Indemnification Claim under the Escrow Agreement shall constitute
an election of


                                      31
<PAGE>   35

remedies nor limit the Indemnified Party in any manner in the enforcement of
any other remedies that may be available to it.

                                   ARTICLE 8
                                  TERMINATION

Per-Se; or

                           (b)      By either Party (provided that the
terminating Party is not then in material breach of any representation,
warranty, covenant, or other agreement contained in this Agreement) in the
event of a breach by the other Party of any representation or warranty
contained in this Agreement which cannot be or has not been cured within 30
days after the giving of written notice to the breaching Party of such breach;
or

                           (c)      By either Party (provided that the

event of a material breach by the other Party of any covenant or agreement
contained in this Agreement which cannot be or has not been cured within 30
days after the giving of written notice to the breaching Party of such breach;
or

                           (d)      By either Party in the event any Consent of
any Regulatory Authority required for consummation of the Stock Purchase and
the other transactions contemplated hereby shall have been denied by final
nonappealable action of such authority or if any action taken by such authority
is not appealed within the time limit for appeal; or

                           (e)      By  either  Party  in the  event  that
the Stock Purchase shall not have been consummated by December 31, 1999, if the
failure to consummate the transactions contemplated hereby on or before such
date is not caused by any breach of this Agreement by the Party electing to
terminate pursuant to this Section 8.1(e); or

                           (f)      By either Party (provided that the
terminating Party is not then in material breach of any representation,
warranty, covenant, or other agreement contained in this Agreement) in the
event that any of the conditions precedent to the obligations of such Party to
consummate the Stock Purchase cannot be satisfied or fulfilled within 60 days
after the giving of written notice to the Party not satisfying the condition
precedent.

                  8.2      Effect of Termination. In the event of the
termination and abandonment of this Agreement pursuant to Section 8.1, this
Agreement shall become void and have no effect, except that (i) the provisions
of Section 5.3(b), this Section 8.2 and Article 9 shall survive any such
termination and abandonment, and (ii) a termination pursuant to Sections
8.1(b), 8.1(c), 8.1(e) or 8.1(f) shall not relieve the breaching Party from
Liability for an uncured willful breach of a representation, warranty,
covenant, or agreement giving rise to such termination.

                  9.6      Waivers.

                           (a)      Prior  to or on the  Closing  Date,  the
Purchaser, acting through its Board of Directors, chief executive officer or
other authorized officer, shall have the right to waive any Default in the
performance of any term of this Agreement by Per-Se, Holdings or the Company,
to waive or extend the time for the compliance or fulfillment by Per-Se,
Holdings or the Company of any and all of its obligations under this Agreement,
and to waive any or all of the conditions precedent to the obligations of
Purchasers under this Agreement, except any condition which, if not satisfied,
would result in the violation of any Law. No such waiver shall be effective
unless in writing signed by duly authorized officers of the Purchaser.

                           (b)      Prior to or on the Closing  Date,  Per-Se,
acting through its Board of Directors, chief executive officer or other
authorized officer, shall have the right to waive any Default in the
performance of any term of this Agreement by the Purchaser, to waive or extend
the time for the compliance or fulfillment by the Purchaser of any and all of
its obligations under this Agreement, and to waive any or all of the conditions
precedent to the obligations of the Per-Se under this Agreement, except any
condition which, if not satisfied, would result in the violation of any Law. No
such waiver shall be effective unless in writing signed by duly authorized
officers of the Seller.

                           (c)      The  failure  of any  Party  at any  time
or times to require performance of any provision hereof shall in no manner
affect the right of such Party at a later time to enforce the same or any other
provision of this Agreement. No waiver of any condition or of the breach of any
term contained in this Agreement in one or more instances shall be deemed to be
or construed as a further or continuing waiver of such condition or breach or a
waiver of any other condition or of the breach of any other term of this
Agreement.

                  9.7      Assignment. Except as expressly contemplated hereby,
neither this Agreement nor any of the rights, interests or obligations
hereunder shall be assigned by any Party hereto (whether by operation of Law or
otherwise) without the prior written consent of the other Party; provided, that
Purchaser may assign its rights and its obligations to a Subsidiary and may
assign its rights but not its obligations under this Agreement or under any
other Closing Document as collateral to any lenders providing financing to
Purchaser in connection with the transactions contemplated by this Agreement.
Notwithstanding any such assignment(s), the Purchaser shall not be relieved of
any of its obligations hereunder. Subject to the preceding, this Agreement will
be binding upon, inure to the benefit of and be enforceable by the Parties and
their respective successors and assigns.

                  9.8      Notices. All notices or other communications which
are required or permitted hereunder shall be in writing and sufficient if
delivered by hand, by facsimile transmission, by registered or certified mail,
