                            STOCK PURCHASE AGREEMENT


                  THIS STOCK PURCHASE AGREEMENT (the "Agreement"), made this
22nd day of June, 1998, by and between Osage Systems Group, Inc., a Delaware
corporation ("Buyer"), and John Udelhofen, Michael Durbin, David Durbin and
Brian Wolfe, the shareholders (collectively, the "Shareholders") of Open
Business Systems, Inc., an Illinois corporation (the "Company").

                                   WITNESSETH:

                  WHEREAS, the Shareholders own 100% of the issued and
outstanding capital stock of the Company, which stock consists of an aggregate
of 1600 shares of common stock, no par value (the "Shares"); and

                  WHEREAS, the Shareholders desire to sell, and Buyer desires to
purchase, all of the Shares for the consideration and on the terms set forth
herein.

                  NOW, THEREFORE, for and in consideration of the premises and
the mutual covenants and agreements set forth in this Agreement and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound hereby, the parties hereto agree
as follows:

                                    ARTICLE I
                           SALE AND TRANSFER OF SHARES

1.1      Sale and Purchase of the Shares.

         Subject to the terms and conditions of this Agreement, at the "Closing"
(as defined herein), the Shareholders shall sell, assign, transfer, convey and
deliver to Buyer, and Buyer shall purchase and accept from Shareholders, the
Shares, in the manner and for the consideration set forth in this Article .

1.2      Consideration.

         The Shareholders shall deliver to Buyer good and sufficient
certificates for the Shares, duly assigned in blank, with any required transfer
stamps or taxes paid and affixed thereto and cause the entire right, title and
interest in and to the Shares to be transferred of record to Buyer, free and
clear of any claim, suit, proceeding, call, commitment, voting trust, proxy,
restriction, limitation, security interest, pledge, lien or encumbrance of any
kind or nature whatsoever, other than restrictions under the Securities Act of
1933, as amended (the "Act"), or applicable state securities laws; and in
consideration thereof Buyer shall pay and deliver to the Shareholders as the
purchase price for the Shares, the following:

         (a) At the Closing, subject to Section 1.5 relating to the deposit of
the "Escrow Consideration" (as defined below), the sum of Two Million Dollars
($2,000,000) in cash,
<PAGE>   7
cashier's check or by wire transfer to the account (or accounts) specified in
writing to Buyer at least three (3) days prior to Closing (the "Cash
Consideration").

         (b) At the Closing, also subject to Section 1.5, delivery of
certificates representing that number of shares of the common stock, par value
$0.01 per share, of Buyer (the "Osage Stock") having an aggregate Closing value
(the "Closing Value") equal to $2,000,000 (the "Stock Consideration"), as
adjusted pursuant to the succeeding sentences. For purposes of the Agreement,
the Closing Value shall be determined based upon the lesser of: (x) $6.00 per
share of Osage Stock, or (y) the average closing price on the OTC Bulletin Board
of the Osage Stock for the ten (10) trading days immediately preceding the third
trading day preceding the "Closing Date" (as defined herein). By way of
illustration, if the average closing price pursuant to clause (y) is $5 per
share, the Shareholders would be entitled to receive 400,000 shares ($2,000,000
/ $5) but, if the average closing price pursuant to clause (y) is $8 per share,
the Shareholders would be entitled to receive 333,333 1/3 shares ($2,000,000 /
$6), having an aggregate value of $2,666,666.67 (333,333 1/3 x $8).

         (c) Subsequent to Closing, the Shareholders, as additional
consideration for the Shares, shall be entitled to receive additional shares of
Osage Stock ("Additional Shares"), having a value of up to a maximum of
$1,000,000 for each "Measurement Period," as defined below (the "Maximum
Earn-Out"), depending upon the Company's achievement of certain levels of sales
revenue and pre-tax net income (the "Earn-Out"). The Earn-Out shall continue
over the three (3) years immediately following the Closing Date (the "Earn-Out
Period") and shall be calculated for each one year period beginning on July 1
and ending on June 30 of the following year (each, a "Measurement Period") in
the manner set forth in Section 1.3 hereof.

                  Clauses (a) - (c), together with the Adjustment Amount, as
provided in Section 1.4 herein, shall constitute the "Purchase Price".

         (d) The Purchase Price shall be allocated among and issued to the
Shareholders in the proportion of their share ownership of the outstanding
common stock of the Company at the Closing in accordance with the percentages
identified on Schedule 3.3 hereof.

         (e) The Stock Consideration and any Additional Shares of Osage Stock,
when and if delivered, shall be fully paid and non-assessable and shall be free
an clear of all liens, levies and encumbrances except that all of such Osage
Stock shall be "restricted securities" pursuant to Rule 144, promulgated under
the Act.

         (f) In the event of any share dividend share split, recapitalization,
merger, consolidation, combination or share exchange involving Osage Stock (a
"Corporate Restructuring") and the Shareholders shall then own any Osage Stock,
the Shareholders shall be entitled to participate in the Corporate Restructuring
to the same extent as all other owners of Osage Stock. Further, to the extent
there is any Corporate Restructuring prior to the end of the Earn-Out Period,
the Additional Shares which have not yet been issued pursuant to Section 1.3
shall be appropriately adjusted to apply to and pertain to the number and class
of securities which would have been issued to the Shareholders in connection
with the Corporate Restructuring had


                                      -2-
<PAGE>   8
such Additional Shares been issued to the Shareholders immediately prior to such
transaction, and an appropriate adjustment shall also be made to the price per
share described in Section 1.3(h), if required.

1.3      Calculation of Earn-Out.

         (a)      Year One.

                  (i)      Sales Revenues:

                           (A) If during the first Measurement Period following
Closing ("Year One"), the Company generates sales revenues between $10,000,000
and $15,000,000, Additional Shares shall be issued having a value equal to the
product of $500,000 and the percentage calculated by dividing the amount by
which the revenues exceeded $10,000,000 by 5,000,000. For example, if sales
revenues of $12,500,000 are achieved, then the Shareholders shall be issued such
Additional Shares having a value equal to $250,000 [$500,000 x ($12,500,000 -
$10,000,000) / 5,000,000].

                           (B) If during Year One, the Company generates sales

revenues of less than $10,000,000, no Additional Shares shall be issued under
this clause (i).

issued having a value equal to the product of $500,000 and the percentage
calculated by dividing the amount by which the pre-tax net income realized
exceeded $400,000 by 200,000. For example, if pre-tax net income of $500,000 is

Additional Shares having a value equal to $250,000.

                           (B) If during Year Two, the Company generates sales

                           (C) If during Year Two, the Company realizes pre-tax
net income of less than $480,000, no Additional Shares shall be issued under

<PAGE>   10
                           (B) If during Year Three, the Company generates sales
revenues in excess of $21,000,000, Additional Shares shall be issued under this

                  (ii)     Pre-Tax Net Income:

                           (A) In addition to any Additional Shares issued

pre-tax net income of less than $600,000, no Additional Shares shall be issued
under this clause (ii).

         (d) For purposes of this Section 1.3, the term "sales revenue" shall be
defined as gross revenues of the Company less any and all discounts, allowances
and returns.

         (e) For the purposes of this Section 1.3, the term "pre-tax net income"
shall be calculated by Buyer's independent auditors in conformity with generally
accepted accounting principles (subject to the application of subsection (f)
below), and consistent with the past practices and accounting methods of the
Company without reduction for administrative/overhead charges other than
reasonable out-of-pocket costs actually paid by Buyer on behalf of Company. If
the Shareholders dispute the determination of Buyer's auditors with respect to
pre-tax net income, Shareholders may, at their own cost, retain independent
auditors to review such determination. Following such review, if Shareholders
continue to dispute the determination of Buyer's auditors, the parties may
submit the matter to arbitration in accordance with the terms of Section 10.8
hereof; provided, however, that in the event that the Shareholders prevail in
arbitration, Buyer shall reimburse the Shareholders for the fees and costs
incurred in connection with the review.

         (f) The Earn-Out is intended by the parties as additional consideration
for the Shares, and towards that end, the integrity of the Company as a separate
accounting and operating unit will be preserved. Consistent with the foregoing,
the "sales revenue" and "pre-tax net income" of the Company shall be determined
on a stand-alone basis and shall not include the sales, net income, net loss or
other operating results associated with or realized by the Company from any


                                      -5-
<PAGE>   11
subsidiaries or interests in other companies owned or acquired by the Company
whether as a result of Section 5.16 hereafter, or otherwise. In the event that
the Company acquires another entity during a Measurement Period, "pre-tax net
income" shall exclude the costs associated with such acquisitions.

         (g) The "sales revenue" and "pre-tax net income" of the Company shall
be determined as soon as possible, but in all events within ninety (90) days
after the expiration of each Measurement Period, and at such time the Buyer
shall deliver such Additional Shares to the Shareholders on a pro rata basis in
accordance with the percentage interests of each Shareholder as set forth on
Schedule 3.3 hereto, accompanied by a certificate of Buyer's Chief Financial
Officer attesting to the method by which, and including the financial statements
with reference to which, the number of Additional Shares were calculated. If any
two of the Shareholders notify the Buyer that they object to the computations
set forth in the aforesaid certificate, and the Buyer and such Shareholders
shall not reach agreement on such issues within 30 days after such notification,
the parties shall submit the issue to Buyer's independent auditors for their
review and determination. Thereafter, if any two of the Shareholders disagree
with the determination of Buyer's independent auditors, then the issue shall be
submitted to arbitration by a nationally recognized accounting firm independent
of any of the parties hereto as shall be mutually acceptable to the Buyer and
such Shareholders for resolution of the disagreement, it being agreed that the
Buyer will share half of the fees and expenses of such accounting firm and the
Shareholders in the aggregate, will share half of the fees and expenses of such
accounting firm.

         (h) The number of Additional Shares to be distributed to the
Shareholders pursuant to subparagraph 1.3(a)-(c) above shall be determined by
dividing the value of such Additional Shares (as so established) by the price
determined based on the lesser of (i) the average closing price of Buyer's
common stock for the ten (10) trading days immediately preceding the date of
issuance thereof, or (ii) $7.00 per share. By way of illustration, if the
average Closing price pursuant to clause (i) is $6 per share, the Shareholders
would be entitled to receive 166,666 2/3 shares (1,000,000 / $6), but if the
average closing price pursuant to clause (i) is $9 per share, the Shareholders
would be entitled to receive 142,857.14 shares(1,000,000 / $7) having an
aggregate value of $1,285,714.29 (142,857.14 x $9).

1.4      Adjustment Amount.

         Buyer agrees to pay to the Shareholders, in cash, the difference
between (i) the "Registration Value" (as defined below) of the Stock
Consideration on the "Registration Date" (also as defined below), and (ii)
$2,000,000, provided the Registration Value is lower than $2,000,000 (such
lesser amount hereinafter referred to as the "Adjustment Amount"). The
"Registration Value" shall be an amount equal to the average closing price per
share of the Osage Stock on the principal exchange, market or quotation system
upon which such shares regularly trade at the time, for the twenty (20) trading
days preceding the "Registration Date" multiplied by the number of shares of the
Osage Stock included in the Stock Consideration. The "Registration Date" shall
be defined as the earlier of (i) the date that the public resale of such shares
is permitted pursuant to an effective registration statement filed with the
Securities and Exchange

                                      -6-
<PAGE>   12
Commission; or (ii) the date that the public resale of some or all of the Shares
is permitted by virtue of Rule 144 promulgated under the Act , to the extent
that Rule 144 permits the public resale of such shares. In the absence of an
effective registration statement, the Adjustment Amount shall only be determined
as to that number of shares of the Stock Consideration that may be publicly
resold pursuant to Rule 144. The determination shall be made separately for each
share of Osage Stock owned by the Shareholders as the "Registration Date" for
each such share of Osage Stock occurs. Payment of the Adjustment Amount shall be
made within fifteen (15) days of the determination thereof.

1.5      Escrow Consideration.

         (a) At the Closing, Buyer shall deposit into escrow the components of
the Purchase Price identified in subparagraph 1.5(b) hereafter (the "Escrow
Consideration"). The Stock Consideration component set forth below shall serve
on a non-exclusive basis as collateral for the indemnification obligations of
the Shareholders pursuant to this Agreement, and the Cash Consideration
component set forth below shall be offset against the "Deficiency" as provided
in Section 5.10 hereof. Buyer consents to the appointment of Levenfeld,
Eisenberg, Janger & Glassberg as the escrow agent (the "Escrow Agent"). The
deposit, maintenance and ultimate disposition of the Escrow Consideration shall
be governed by the terms of an escrow agreement, the form of which is attached
hereto as Exhibit A (the "Escrow Agreement").

         (b) The Escrow Consideration shall consist of:

                  (i) 10% of the Cash Consideration identified in Section 1.2(a)
herein (the "Escrow Cash"); and

                  (ii) 50% of the shares of the Stock Consideration identified
in Section 1.2(b) herein (the "Escrow Shares").

1.6      Incremental Tax Amount.

         (a) It is intended by the parties that the transactions covered by this
Agreement, shall not be treated by the parties as a tax-free reorganization
under the Internal Revenue Code of 1986, as amended (the "Code") As further
provided in Section 5.14, a Code Section 338(h)(ii) election will be made for
tax purposes. Buyer intends that the Shareholders should not be burdened by tax
greater (or sooner) than that which they would have suffered had the transaction
qualified as a tax-free reorganization under the Code. To that end, Buyer shall,
from time to time loan to the Shareholders sums equal to the incremental amount
of federal and state (if any) income taxes incurred by each of them in
connection with the sale of their Shares, in excess of the amount of such
federal and state income taxes that would have been incurred by them as a result
of the sale of their Shares, had the transaction been structured as a tax free
reorganization under the Code. Such amount is hereinafter referred to as the
"Incremental Tax Amount." The Incremental Tax Amount shall be loaned to the
Shareholders no later than 15 days prior to the date on which each such
Shareholder's income tax return is due for filing (or on such earlier dates that
estimated tax payments are due) and a copy of such tax returns shall once filed,
be provided



                                      -7-
<PAGE>   13
to the Buyer to verify the timely submission of such returns. Such
loans shall be made pursuant to the terms of a promissory note, a form of which
is attached hereto as Exhibit B (the "Note"), to be executed by the Shareholder
upon advancement of the Incremental Tax Amount. Said Note shall be secured by a
pledge, pursuant to a pledge agreement (the "Pledge Agreement"), a form of which
is attached hereto as Exhibit C, of that portion of the Stock Consideration
received by the Shareholder having a value equal to the principal amount of the
Note. Buyer does not indemnify Seller for any tax consequences of the notes
being non-interest bearing to the extent interest must be imputed for federal
income tax purposes on such advances.

         (b) The amount and due dates for advances of the Incremental Tax Amount
to the Shareholders shall be provided by the Shareholders in written notices
(each a "Tax Notice") to the Buyer no later than 60 days prior to each required
payment hereunder. Buyer shall have 20 days in which to review the Tax Notice
and shall advise the Shareholders of any objection to the same. If Buyer objects
to the computation of the Incremental Tax Amount or the due dates associated
therewith, and the Buyer and the Shareholders shall not reach agreement on such
issues within 30 days after Buyer has notified the Shareholders of its
objection, the Buyer and Shareholders shall submit the issue to arbitration by a
nationally recognized accounting firm independent of any of the parties hereto
as shall be mutually acceptable to the Buyer and the majority of the
Shareholders for resolution of the disagreement, it being agreed that the Buyer
and each of the Shareholders will jointly share the fees and expenses of such
accounting firm. Notwithstanding any dispute or arbitration which may arise
pursuant hereto, Buyer shall advance to Shareholders that portion of the
Incremental Tax Amount requested by Shareholders in the Tax Notice which is not
disputed or objected to by Buyer, such advance to occur within 30 days after
delivery of the Tax Notice.

used by the Company in the operation of its business (the "Names and Service
Marks"). The Company owns, or has enforceable rights to use all intellectual
property presently in use by it and necessary for the operation of its business
as now being conducted, which intellectual property includes, but is not limited

patent, invention, trademark, copyright, service mark or tradename of any

Property subject hereto. There is no presently known threatened use or
encroachment of any such Intellectual Property. To the knowledge of the

date information before, during, and after January 1, 2000, including but not
limited to accepting date input, providing date output, and performing

accordance with the published documentation, and without interruption before,
during, and after January 1, 2000, without any change in operations associated
with the advent of the new century; (c) respond to two-digit year-date input in
a way that resolves any ambiguity as to century in a disclosed, defined, and
predetermined manner; and (d) store and provide output of date information in
ways that are unambiguous as to century. This paragraph (b) shall not apply to
third party software purchased or licensed by the Company for use in its
business.

Shareholders pursuant to the terms of the Registration Rights Agreement, the
shares included in the Stock Consideration are not being registered under the
Act on the basis of the statutory exemption provided by Section 4(2) thereof,
relating to transactions not involving a public offering, and the Buyer's
reliance on the statutory exemption thereof is based in part on the

accordance with Rule 144, an applicable exemption from registration under the
Act, or except as otherwise provided in this Agreement; (iii) that the Osage
Stock will be held for investment and not with a view to, or for resale in
connection with the public offering or distribution thereof; (iv) that the Osage
Stock so issued will not be sold without registration thereof under the Act
(unless such shares are subject to registration or in the opinion of counsel to
the Buyer an exemption from such registration is available), or in violation of
any law; and (v) that the certificate or certificates representing the Osage
Stock to be issued will be imprinted with a legend in form and substance
substantially as follows:

5.4      Permissible Distributions to Shareholders.

         (a) In recognition of the Company's status as an S Corporation, Buyer
has agreed to permit the Shareholders to withdraw from the Company funds to
assist each of the Shareholders in the payment of the Shareholders' federal and
state income tax liability for the taxable earnings of the Company for the
fiscal year ended December 31, 1997 in an aggregate amount (to the extent such
distributions have not already been withdrawn by the Shareholders) not to exceed
$125,000.

         (b) In connection with the Shareholders' federal and state income tax
liability from January 1, 1998 through the Closing Date, the Shareholders may
withdraw funds from the Company in an amount estimated to be equal to the
Shareholders' aggregate individual tax liabilities for the taxable earnings of
the Company from January 1, 1998 through the Closing Date, exclusive of any
income or gains resulting from the Section 338(h)(10) election. All amounts not
previously distributed to the Shareholders to cover the taxes described herein,
shall be distributed to the Shareholders once all parties are satisfied as to
the determination of the Company's taxable income from operations from January
1, 1998 through the Closing Date, however, in no event later than the 15th day
prior to the due date of the final S-Corporation tax return for the taxable
period January 1, 1998 through the Closing Date. In the event that the amounts
withdrawn by the Shareholders on or before the Closing Date are greater or less
than the total amount that the Shareholders are cumulatively entitled to
withdraw under this section, then after notice to this effect, Buyer and the
Shareholders, as the case may be, shall make payment to the other to reconcile
the difference within sixty (60) days of such notice, and if such payments are
not timely received within sixty (60) days of such notice, the amount to be paid
by the party so obligated shall be increased by fifteen (15%) percent.

         (c) For the purposes hereof, the tax rate applicable to the taxable
earnings of the Company shall be computed without regard, and prior to, any
additional taxes or increased tax rate caused by the gain on sale associated
with the sale of the Shares covered by this Agreement.

5.5      Consents.

         Buyer and the Shareholders shall cooperate and use their best efforts
to obtain, prior to the Closing, all licenses, permits, consents, approvals,
authorizations, qualifications and orders of governmental authorities and
parties to contracts as are necessary for the consummation of the transactions
contemplated by this Agreement; provided, however, that no loan agreement or
contract for borrowed monies shall be repaid and no contract shall be amended
materially to increase the amount payable thereunder or otherwise to be
materially more burdensome in order to obtain any such consent, approval or
authorization without first obtaining the written approval of the other parties
hereto.

5.6      Filings.

         (a) Buyer and the Shareholders shall, as promptly as practicable, make
any required filing, and any other required submissions, under any law, statute,
order rule or regulation with 

                                     - 34 -
<PAGE>   40
respect to the Agreement and the related transactions and shall cooperate with
each other with respect to the foregoing. After the Closing, Buyer shall timely
file a current report on Form 8-K relating to the Agreement and the transactions
contemplated hereby.

         (b) From and after the Closing Date and until at least one year after
the last Measurement Period identified within this Agreement, assuming it
remains the owner of the outstanding stock of the Company, Buyer shall continue
to make all filings required by the Securities and Exchange Commission as may be
necessary to allow the Shareholders to avail themselves of Rule 144.

5.7      All Reasonable Efforts.

         Subject to the terms and conditions of this Agreement and to the
fiduciary duties and obligations of the boards of directors of the parties
hereto to their respective shareholders, as advised by their counsel, each of
the parties to this Agreement shall use all reasonable efforts to take, or cause
to be taken, all action and to do, or cause to be done, all things necessary,
proper or advisable under applicable laws and regulations, or to remove any
injunctions or other impediments or delays, legal or otherwise, as soon as
reasonable practicable, to consummate the transactions contemplated by this
Agreement.

5.8      Public Announcements.

         Neither the Shareholders nor the Buyer shall disclose to the public or
to any third party the existence of this Agreement or the transactions
contemplated hereby or any other material non-public information concerning or
relating to the other party hereto, other than with the express prior written
consent of the other party hereto, except as may be required by law or court
order or to enforce the rights of such disclosing party under this Agreement, in
which event the contents of any proposed disclosure shall be discussed with the
other party before release; provided, however, that notwithstanding anything to
the contrary contained in this Agreement, any party hereto may disclose this
Agreement to any of its directors, officers, employees, shareholders,
affiliates, agents and representative who need to know such information for the
sole purpose of evaluating the Agreement, and to any party whose consent is
required in connection with this Agreement. The parties anticipate issuing a
mutually acceptable, joint press release announcing the execution of this
Agreement and the consummation of the transactions provided for herein.

5.9      Notification of Certain Matters.

The Shareholders shall give prompt notice to Buyer, and Buyer shall give prompt
notice to Shareholders, of (a) the occurrence or non-occurrence of any event,
the occurrence or non-occurrence of which would cause any of its representations
or warranties in this Agreement to be untrue or inaccurate in any material
respect, as to the Company or the Shareholders, at or prior to the Closing, and,
as to Buyer, as of or prior to the Closing and (b) any material failure of the
Shareholders, on the one hand, or Buyer, on the other hand, as the case may be,
to comply with or satisfy any covenant, condition or agreement to be complied
with or satisfied by them 

                                     - 35 -
<PAGE>   41
under this Agreement; provided, however, the delivery of any notice pursuant to
this Section shall not limit or otherwise affect the remedies available to the
party receiving such notice under this Agreement as expressly provided in this
Agreement.

5.10     Financial Statements.

         (a) Within seventy-five (75) days after the Closing, the Company shall
cause to be prepared an audit for the calendar year ending December 31, 1997
(the "Audited Financial Statements"). The Audited Financial Statements shall not
reflect any material adverse changes from the Unaudited Financial Statements. If
the Stockholders' Equity reflected on the Audited Financial Statements is less
than the amount reflected on the Unaudited Financial Statements, less the up to
$125,000 tax distribution described in Section 5.4(a)(i), then the amount of the
difference between the Stockholders' Equity reflected on the Audited Financial
Statement, less the up to $125,000 tax distribution described in Section
5.4(a)(i), and the amount reflected on the Unaudited Financial Statements (the
"Deficiency") shall be applied against the Escrow Cash on a dollar for dollar
basis.

         (b) The cost of the Audited Financial Statements shall be borne by the
Buyer. The Shareholders shall take all reasonable actions and provide whatever
cooperation is necessary to facilitate the prompt preparation of the Audited
Financial Statements.

5.11     Documents at Closing.

         Each party to this Agreement agrees to execute and deliver at the
Closing the Exhibits and other documents identified in Section 2.2.

5.12     Satisfaction of Guarantees.

         Buyer agrees to take all action as may be reasonably required to have
the Shareholders (and their spouses, if applicable) released from the guarantees
and to the extent not so released, shall satisfy or assume in full the
guarantees of Shareholders (and their spouses, if applicable) identified on
Schedule 3.11 hereto as of the Closing Date, and Buyer shall indemnify the
Shareholders (and their spouses, if applicable) against all liabilities
associated with the guarantees from and after the Closing Date.

5.13     Prohibition on Trading in Buyer Stock.

         The Shareholders acknowledge that the United States securities laws
prohibit any person who has received material non-public information concerning
the matters which are the subject matter of this Agreement from purchasing or
selling the securities of the Buyer, or from communicating such information to
any person under circumstances in which it is reasonably foreseeable that such
person is likely to purchase or sell securities of the Buyer. Accordingly, each
Shareholder agrees that he will not purchase or sell any securities of the
Buyer, or communicate such information to any other person under circumstances
in which it is reasonably foreseeable that such person is likely to purchase or
sell securities of the Buyer, until no earlier 

                                     - 36 -
<PAGE>   42
than 72 hours following the dissemination of a Current Report on Form 8-K to the
SEC announcing the Closing pursuant to this Agreement provided that the Form 8-K
is required and timely filed.

5.14     Tax Matters/Section 338(h)(10) Election.

         (a) The Shareholders will timely and properly file or cause to be filed
all tax returns of the Company which are due or which will become due with
respect to periods ending through the Closing Date, all such tax returns to be
true and correct and complete in all material respects, and the Shareholders
will pay or cause to be paid in full when due all taxes, if any, which become
due and payable pursuant to such returns, or assessments received by them on or
before the Closing Date; in that regard, the Company shall provide Shareholders
with such reasonable access to the books and records of the Company as is
necessary to complete and file such tax returns. Shareholders shall present for
Buyer's review and Buyer shall be entitled to review all final federal and state
S-corporation returns which shall include gains, if any, resulting from the
Section 338(h)(10) election to be filed by the parties hereto, thirty (30) days
prior to the filing of any such return. In addition, Shareholders agree that any
and all costs of preparing such return shall be borne exclusively by the
Shareholders.

         (b) The Shareholders and Buyer shall jointly execute Form 8023 at
Closing, and thereafter shall jointly make an election on a timely basis with
respect to the Company under Section 338(h)(10) of the Internal Revenue Code
(the "Code") on Form 8023 or in such other manner as may be required by rule or
regulation of the Internal Revenue Service, and shall jointly make an election
in the manner required under any analogous provision of state or local law as
the Buyer shall designate or as shall be required, concerning the transactions
contemplated by this Agreement. Form 8023 is attached hereto as Exhibit F. The
Buyer shall, with the assistance and cooperation of the Shareholders, prepare
all such Section 338(h)(10) forms required as attachments to Form 8023 (and all
forms under analogous provisions of state or local law) in accordance with
applicable tax laws and shall on such Form 8023 allocate the Purchase Price in a
manner consistent with Section 338 of the Code, and the Buyer shall deliver such
forms and related documents to the Shareholders at least 60 days prior to the
due date of filing. The Form 8023 shall be prepared as to total purchase
consideration, on a basis consistent with the value of the Purchase
Consideration attributed thereto under Paragraphs 1.2(a) and 1.2(b) of this
Agreement. The Shareholders shall deliver to the Buyer at least 30 days prior to
the due date of filing such completed forms as are required to be filed under
Section 338(h)(10) of the Code (and analogous provisions of state or local law).
The Shareholders shall not be obligated to indemnify the Buyer or the Company
for any amount of Illinois replacement tax attributable to the Section
338(h)(10) election. The Shareholders and Buyer shall jointly execute any
amended Form 8023's (and all forms under analogous provisions of state or local
law) as may become necessary after the initial filing to the extent post-closing
adjustments to Purchase Price arise under the provisions of this Agreement.

         (c) The Shareholders and Buyer agree that the fair market value of the
assets shall initially approximate the amount set forth on Schedule 5.14 hereto.
The Shareholders and the 

                                     - 37 -
<PAGE>   43
Buyer agree that following the Closing, the Buyer shall, at its expense, perform
or cause to be performed a complete initial valuation of the assets of the
Company and allocation of purchase price prepared in a manner consistent with
Section 338 of the Code. Buyer shall provide the Shareholders with drafts of
such valuation of assets and allocation of modified aggregate deemed sale price
("MADSP") (as defined under Treasury Regulations) within 150 days after the
Closing Date. If any two or more Shareholders provide notification to the Buyer
that they object to such drafts and shall not reach agreement with Buyer on the
computation or allocation within 30 days after notification, Buyer and
Shareholders shall submit the issue to arbitration to a nationally recognized
accounting firm as shall be mutually acceptable to Buyer and the Shareholders
for resolution of the disagreement within 10 days. The fees and expenses of such
accounting firm shall be borne 50% by Buyer and 50% by the Shareholders (in the
aggregate). The valuations and allocations determined pursuant to this Section
shall be used for purposes of all relevant tax returns, reports and filings.

5.15     Change in Control.

         In furtherance of the general covenant described in Section 1.3(f),
Buyer will not, during the Earn-Out Period, sell or attempt to sell a
controlling interest in the common stock of the Company, or substantially all of
the assets or operations of the Company (a "Change in Control Transaction")
without having first secured the consent of the Shareholders who shall have the
right to review the proposed transaction in order to assure, in their reasonable
judgment, that the proposed Change in Control Transaction will not adversely
affect the ability of the Shareholders to realize the Maximum Earn-Out or
otherwise impair the economic viability of the Company. In the event that the
Shareholders withhold their consent to the Change in Control Transaction in
accordance with the foregoing, Buyer may, nevertheless, proceed with the
proposed Change in Control Transaction provided Buyer pays to the Shareholders
the Maximum Earn-Out, in which event, the Shareholders' right to receive any
Additional Shares in connection the Earn-Out shall terminate. For the purposes
hereof, a Change in Control Transaction shall not include (i) a merger,
reorganization or other transaction resulting in the sale of the stock or a
controlling interest in Buyer, (ii) an overall sale of the operations of Buyer
consisting of the sale of Buyer's stock ownership interest in at least 75% of
its operating subsidiaries; (iii) a sale of a controlling interest in any of
Buyer's principal operating subsidiaries, other than the Company. For purposes
hereof, the Maximum Earn-Out will be calculated with reference to the Maximum
Earn-Out (as defined in Section 1.2(c)) for each Measurement Period that has not
closed, converted into a dollar amount upon application of Section 1.3(h), using
the last trading day of the calendar week prior to the Change of Control
Transaction as the last day of the ten day pricing period in clause (i) of
Section 1.3(h). Payment of the Maximum Earn-Out required hereunder shall be made
on the closing date of the Change in Control Transaction giving rise to the
required payment.

5.16     Subsequent Acquisitions.

Company and whose headquarters or principal operations are located within a 100
mile radius of Chicago, Illinois, subject to subparagraph (b) below, such
acquisitions (i) will be accomplished through the Company such that the acquired
business shall be operated as a direct subsidiary or division of the Company,
and (ii) will not be undertaken without the consent of a majority in interest of
the Shareholders who remain employed by the Company, whose consent shall not be
unreasonably withheld.

         (b) The obligations set forth in subparagraph (a) above shall only
apply if at the time any such acquisition is undertaken, the Shareholders earned
any Additional Shares for the immediately preceding Measurement Period and the
Company is demonstrating, through interim results of operations, a likelihood
that the Shareholders will be entitled to receive Additional Shares for the
current Measurement Period. For acquisitions considered prior to the end of the
first Measurement Period, the Buyer's obligations as set forth in subparagraph
(a) above shall only apply if the Company is demonstrating, through interim
results of operations, a likelihood that the Shareholders will be entitled to
receive Additional Shares for such Measurement Period.

Buyer or the Company; there is no investment banker, broker, finder or other
similar intermediary which has been retained by, or is authorized by, the Buyer

satisfied as of the Closing Date or if satisfaction of such a condition is or
becomes impossible (other than through the failure of Buyer to comply with its
obligations under this Agreement), and Buyer has not waived such condition on or
before the Closing Date; or (ii) by the Shareholders, if any of the conditions
in Article 7 have not been satisfied as of the Closing Date or if satisfaction
of such a condition is or becomes impossible (other than through the failure of
Shareholders to comply with his obligations under this Agreement), and
Shareholders have not waived such condition on or before the Closing Date;

         (c) by mutual consent of Buyer and the Shareholders; or

         (d) by either Buyer or the Shareholders if the Closing has not occurred
(other than through the failure of any party seeking to terminate this Agreement
to comply fully with its obligations under this Agreement) on or before the
Termination Date, or such later date as the parties may agree upon.

8.2      Effect of Termination.

         Each party's right of termination under Section 8.1 is in addition to
any other rights it may have under this Agreement or otherwise, and the exercise
of a right of termination will not be an election of remedies. If this Agreement
is terminated pursuant to Section 8.1, all further obligations of the parties
under this Agreement will terminate, except that the obligations in Sections
10.11, and 5.2 and 5.8 will survive; provided, however, that if this Agreement
is terminated by a party because of the breach of the Agreement by the other
party or because one or more of the conditions to the terminating party's
obligations under this 

                                     - 43 -
<PAGE>   49
Agreement is not satisfied as a result of the other party's failure to comply
with its obligations under this Agreement, the terminating party's right to
pursue all legal remedies will survive such termination unimpaired.

8.3      Extension; Waiver.

         Any time prior to the Closing, the parties may (a) extend the time for
the performance of any of the obligations or other acts of any other party under
or relating to this Agreement; (b) waive any inaccuracies in the representations
or warranties by any other party or (c) waive compliance with any of the
agreements of any other party or with any conditions to its own obligations. Any
agreement on the part of any other party to any such extension or waiver shall
be valid only if set forth in an instrument in writing signed on behalf of such
party.

                                   ARTICLE IX
           INDEMNIFICATION/SURVIVAL OF REPRESENTATIONS AND WARRANTIES

9.1      Indemnification.

         (a) The Shareholders shall jointly and severally indemnify, defend and
hold harmless Buyer from and against any and all demands, claims, actions or
causes of action, judgments, assessments, losses, liabilities, damages or
penalties and reasonable attorneys' fees and related disbursements
(collectively, "Claims") incurred by Buyer which arise out of or result from a
misrepresentation, breach of warranty, or breach of any covenant or agreement of
the Shareholders contained herein or in the Schedules annexed hereto or in any
deed, exhibit, closing certificate, schedule or any ancillary certificates or
other documents or instruments furnished by the Shareholders pursuant hereto or
in connection with the transactions contemplated hereby or thereby.

         (b) Buyer shall indemnify, defend and hold harmless the Shareholders
from and against any and all Claims, as defined at subsection 9.1(a) above,
incurred by the Shareholders which arise out of or result from a material
misrepresentation, breach of warranty or breach of any covenant of Buyer
contained herein or in the Schedules annexed hereto or in any deed, exhibit,
closing certificate, schedule or any ancillary certificates or other documents
or instruments furnished by Buyer pursuant hereto or in connection with the
transactions contemplated hereby or thereby.

         (c) The right to indemnification, payment of damages or other remedy
based on any representations, warranties, covenants and obligations contained
within this Agreement will not be affected by any investigation conducted with
respect to, or any knowledge acquired (or capable of being acquired) at any
time, whether before or after the execution and delivery of this Agreement or
the Closing Date, with respect to the accuracy or inaccuracy of or compliance
with, any such representation, warranty, covenant or obligation. The waiver of
any condition based on the accuracy of any representation or warranty, or on the
performance of or compliance with any covenant or obligation, will not affect
the right to indemnification, payment of damages, or other remedy based on such
representations, warranties, covenants and obligations.

                                     - 44 -
<PAGE>   50
9.2      Survival.

         (a) All representations and warranties contained in or made pursuant to
this Agreement or in any agreement, certificate, document or statement delivered
pursuant hereto shall survive the Closing for a period of one (1) year from the
Closing Date, unless otherwise specified in such agreement, certificate or
document; provided, however, that notwithstanding the foregoing, (i) the
representations and warranties set forth in Section 3.31 (relating to
environmental matters) and 3.12 (relating to taxes) and all covenants and
agreements of the parties relating to the subject matter(s) thereof shall
survive the Closing for the period equal to the statute of limitations
applicable to Claims arising under such subject matters.

9.3      Methods of Asserting Claims for Indemnification.

         All claims for indemnification under this Agreement shall be asserted
as follows:

         (a) Third Party Claims. In the event that any Claim for which a party
(the "Indemnitee") would be entitled to indemnification under this Agreement is
asserted against or sought to be collected from the Indemnitee by a third party
the Indemnitee shall promptly notify the other party (the "Indemnitor") of such
Claim, specifying the nature thereof, the applicable provision in this Agreement
or other instrument under which the Claim arises, and the amount or the
estimated amount thereof (the "Claim Notice"). The Indemnitor shall have thirty
(30) days (or, if shorter, a period to a date not less than ten (10) days prior
to when a responsive pleading or other document is required to be filed but in
no event less than ten (10) days from delivery or mailing of the Claim Notice)
(the "Notice Period") to notify the Indemnitee (a) whether or not it disputes
the Claim and (b) if liability hereunder is not disputed, whether or not it
desires to defend the Indemnitee. If the Indemnitor elects to defend by
appropriate proceedings, such proceedings shall be promptly settled or
prosecuted to a final conclusion in such a manner as to avoid any risk of damage
to the Indemnitee; and all costs and expenses of such proceedings and the amount
of any judgment shall be paid by the Indemnitor.

         If the Indemnitee desires to participate in, but not control, any such
defense or settlement, it may do so at its sole cost and expense. If the
Indemnitor has disputed the Claim, as provided above, and shall not defend such
Claim, the Indemnitee shall have the right to control the defense or settlement
of such Claim, in its sole discretion, and shall be reimbursed by the Indemnitor
for its reasonable costs and expenses of such defense. Neither Indemnitee nor
Indemnitor shall be liable for any settlement of any Claim without the prior
written consent of the other party.

         (b) Non-Third Party Claims. In the event that the Indemnitee should
have a Claim for indemnification hereunder which does not involve a Claim being
asserted against it or sought to be collected by a third party, the Indemnitee
shall promptly send a Claim Notice with respect to such Claim to the Indemnitor.
If the Indemnitor does not notify the Indemnitee in writing within thirty (30)
days of the date of the Claim Notice, then such Claim shall be submitted to
arbitration pursuant to Section 10.8 hereof. If the Indemnitor disputes the
amount of such Claim, the controversy in question shall be submitted to
arbitration pursuant to Section 10.8 hereafter.

                                     - 45 -
<PAGE>   51
         (c) Right of Set-Off. Subject to the terms of the Escrow Agreement, in
the event a Claim arises pursuant to subparagraph 9.1(a), in addition to any of
its other rights under this paragraph 9, Buyer shall have the right to apply the
amount of the Claim which is agreed to by the other party against the amounts
identified at subparagraph 1.4; provided, however, that this subparagraph shall
not be the exclusive remedy of Buyer in the event a Claim arises pursuant to
subparagraph 9.1(a).

9.4      Limitations on Amount.

         (a) Notwithstanding the provisions of this Article 9, the Indemnitor
shall not be required to indemnify the Indemnitee with respect to Claims (other
than Claims relating to tax matters and environmental matters and all costs of
defense for any such Claim), until the aggregate amount of such Claims shall
exceed $50,000 (the "Indemnitor's Floor"); provided, however, if such Claims in
the aggregate exceed the amount of the Indemnitor's Floor, the Indemnitor shall
indemnify Indemnitee for all Claims in excess of the Indemnitor's Floor. The
Indemnitor's Floor shall not be applicable to Claims that relate to tax matters
and environmental matters and all costs of defense for any such Claims. To the
extent that any Claim is predicated on the uncollectability of an account
receivable to the extent that it exceeds the Indemnitor's Floor, the receivable
in question shall be assigned to Shareholders as a condition of Buyer's Claim.

         (b) Notwithstanding the provisions of this Article 9, the Buyer's
liability with respect to matters set forth in subsection 9.1(b) above for
damages shall be limited to the amount of the Purchase Price. The Shareholders'
aggregate liability with respect to matters set forth in subsection 9.1(a) shall
also be limited to One Million Dollars ($1 million), except for damages arising
out of a breach of the representations and warranties at Sections 3.1 to 3.6
inclusive, Sections 3.12 and 3.31, and any and all fraudulent actions, in which
case the maximum liability of the Shareholders shall be limited to the Purchase
Price.

                                    ARTICLE X
                                  MISCELLANEOUS

10.1     Exclusive Remedies.

         The right to indemnification under Article IX of the Agreement shall be
the exclusive remedy for a breach of a representation, warranty, covenant or
other provision of this Agreement except that Buyer and the Shareholders shall
have the right to obtain injunctive relief to restrain any breach or otherwise
to specifically enforce the provisions of this Agreement, it being agreed by the
parties that money damages alone would be inadequate to compensate Buyer or the
Shareholders, as the case may be, for such breach or other failure to perform
the obligations under this Agreement.
