                                   THE CLOSING

         2.1  TIME AND PLACE OF CLOSING. The Closing will take place on the
Effective Date at 10:00 a.m. (as prevailing in the Central Time Zone) at the

time and place on the Effective Date as may be mutually agreed upon by Purchaser

Date. The Effective Date shall be the date which is 5 Business Days after the
last to occur of the dates on which the conditions set forth in Articles XII and

         2.2  ACQUISITION OF THE SHARES. (a) At the Closing, on the terms and
subject to the conditions set forth in this Agreement, and on the basis of the
representations and warranties, covenants and agreements set forth in this

<PAGE>   8

Entities provided pursuant to Section 11.6 hereof; (ii) the amount (the "Asset
Amount") of the positive aggregate Net Book Value (as defined in Section 2.2(c)
of the assets of On-Line and the Service Corps, as such assets are reflected in
accordance with GAAP on the Closing Balance Sheet, and (iii) such amount (the
"Contingent Payment") equal to the difference between $10 million and the Asset
Amount, but payable solely from and to the extent of Designated Funds that are
realized by On-Line (or any successor thereto) during, and determined with
respect to, the period from the Effective Date to the seventh anniversary of the
Effective Date (such period, the "Revenue Period"). The Asset Amount shall be
payable to the Agent in accordance with the terms of the promissory notes (the
"Asset Notes") in the form of Exhibit B. The Contingent Payment shall not accrue
interest or other charges with respect to the dates on which any part thereof
may be paid. Designated Funds shall be payable against the Asset Notes and the
Contingent Payment only on and after 60 calendar days after the last day of
On-Line's fiscal year end (which year end Purchaser shall cause to be changed to
December 31st subsequent to the Effective Date) with respect to which the amount
of Designated Funds are determinable. No part of the Contingent Payment shall be
payable until all of the Asset Amount shall have been paid or be payable.

         The Purchase Price shall be payable to the Selling Entities in the
following percentages:

                        ISC Stockholders           74.8%
                        SLI Stockholders           22.2%

                        Superior                    1.1%

         With respect to any and each payment of the Purchase Price to the Agent
on behalf of the Selling Entities, each Selling Entity agrees that the Agent
shall receive such payment as the agent for, and on behalf of, such Selling
Entity.

         (b) In such amounts as any of the following are not accrued on the
Closing Balance Sheet, the Purchase Price and the remaining principal amount of
the Asset Notes (and, if required, amounts due as the Contingent Payment) shall
be adjusted by the following items, prorated (if applicable) to the Effective
Date: (i) increased by security deposits and prepaid license fees and expenses
from which the Business of On-Line and the Service Corps directly derives
quantifiable economic benefit, prorated to the Effective Date; and (ii)
decreased by advance user deposits, deferred income, real estate taxes, personal
property taxes, ad valorem taxes, rent, and other unpaid expenses payable in
arrears including employee compensation and related expenses.

         (c) Not more than 90 calendar days after the Effective Date, the
Selling Entities shall prepare and promptly deliver to Purchaser audited
consolidated Balance Sheets of On-Line and the Service Corps as of the Effective
Date (the "Closing Balance Sheet"), which shall have been prepared in accordance
with GAAP, applied on a consistent basis with the application thereof in
preparing the Balance Sheets. The Selling Entities shall also then state the
amount of the net book value reflected in the Closing Balance Sheet (the "Net
Book Value"). Within the 60 calendar days following delivery of the Closing
Balance Sheet to Purchaser, Purchaser, at its sole expense, may audit or review
the Closing Balance Sheet and may propose any adjustments Purchaser believes
should be made to the Closing Balance Sheet. If the Selling Entities and
Purchaser fail to agree on any adjustment to the Closing Balance Sheet proposed
by Purchaser, then an independent accounting firm mutually selected by Purchaser
and the Selling Entities shall make a determination of the appropriateness of
any such proposed adjustment which determination shall be final and binding on
all parties. After delivery of the Closing Balance Sheet and completion of any
such audit or review, proposed adjustments and further determination, the
remaining principal amount of the Asset Notes and (if required) amounts due as
the Contingent Payment shall be adjusted, dollar for dollar, as follows: (i)
increased by the amount by which the Net Book Value as of the Effective Date
exceeds the Asset Amount; or (ii) decreased by the amount by which Asset Amount

                                       7
<PAGE>   9

exceeds the Net Book Value as of the Effective Date.

         (d) Except as provided in Sections 14.2 and 10.18, notwithstanding
anything to the contrary contained in this Agreement or the Asset Notes, the
Selling Entities agree that in addition to adjustments pursuant to Sections
2.2(b) or 2.2(c), Purchaser shall be entitled to credit and offset against any
payments due to any of the Selling Entities by Purchaser as a result of the
transactions contemplated hereby (including by way of the Asset Notes and the
Contingent Payment), an aggregate amount equal to all amounts due to Purchaser
by any of the Selling Entities under this Agreement or any other agreement
furnished or to be furnished by any of the Selling Entities to Purchaser
pursuant thereto, including, without limitation, (i) amounts due pursuant to
Article XIV, (ii) amounts of any expenses relating to the period prior to the
Effective Date that have been deferred to the period after the Effective Date,
(iii) amounts of any revenue relating to the period after the Effective Date
that was received by On-Line prior to the Effective Date, (iv) if not otherwise
taken into account in determining the Purchase Price, the amount of any decrease
in Net Book Value from that initially determined pursuant to Section 2.2(b), and
(v) payments to the Selling Entities pursuant to Section 11.6. No such offset
shall be made without thirty (30) business days prior written notice to the
Agent, which notice shall state the nature of the items comprising the offset
and shall include copies of all supporting documentation evidencing same. Any
such offset shall be made first against the Asset Notes and then against the
Contingent Payment. The exercise of such right to offset if made in good faith
by Purchaser shall not constitute a breach or violation of the provisions of
this Agreement or any other agreement contemplated hereby and shall not be
construed to be the sole and exclusive remedy of Purchaser.

         (e) If a Service Corp is unable to procure: (i) the unanimous written
consent of all of its shareholders to the terms of this Agreement and (ii) the
tender to Purchaser by such shareholders of all their stockholdings in such
Service Corp, then Purchaser, upon delivery of written notice to Agent, within
ten (10) days of its obtaining knowledge of such Service Corps's inability to
procure the foregoing items (i) and (ii), shall have the option to proceed with
the transactions contemplated by this Agreement, as modified by this
subparagraph 2(e), with the parties who are then signataries to this Agreement.
In such event, Purchaser and such Service Corp shall agree upon an amount to be
withheld from that portion of the Purchase Price payable to such Service Corp
pursuant to the terms of Section 2.2(a) and such amount shall be deposited (out
of the proceeds to be distributed to such Service Corp pursuant to Section
10.14) in a joint order escrow between Purchaser and the Agent, at a mutually
agreed upon financial institution, upon terms agreed upon by Purchaser, such
Service Corp and the Agent.

Business, in all material respects, immediately subsequent to the Closing in
substantially the same manner as was carried on and conducted prior to the

         4.6  COMPLIANCE WITH LAW. Except as otherwise disclosed herein,
On-Line: (a) has substantially complied with all Legislative Enactments and
Official Actions applicable to the On-Line Business or the capital stock of
On-Line, (b) has duly and timely made all filings and submissions that are
required by Legislative Enactments or Official Actions to be made with respect
to the On-Line Business or the capital stock of On-Line, (c) has obtained and
put into place all licenses and regulatory approvals necessary for operation and
continuation of the On-Line Business, and (d) has no knowledge of any facts
which, upon examination, may reasonably be interpreted to form the basis of an

Actions, non-timely filing or submission under Legislative Enactments or
Official Actions, or non-procurement or failure to put into place licenses and
regulatory approvals necessary for operation and continuation of the On-Line
Business.

         4.7  CAPITALIZATION OF ON-LINE. The total number of shares of capital
stock (and the par value thereof) which On-Line is authorized to issue, and the
number of such shares which are issued and outstanding are set forth on Schedule
4.7. Schedule 4.7 sets forth a list, by On-Line Stockholders, of: (a) each
record holder of any shares of capital stock or other Ownership Interests of
On-Line, accurately setting forth the number and class of such shares or other
Ownership Interests held by each person, and (b) each record holder of any
outstanding rights, warrants, options, puts, calls, convertible securities or
convertible indebtedness, exchangeable securities or exchangeable indebtedness,
or other rights, exercisable for or convertible or exchangeable into, directly
or indirectly, common stock or other Ownership Interests of On-Line, whether as
of the date of this Agreement or upon the occurrence of some future event (the
foregoing, "Capital Stock Equivalents"), accurately setting forth the number and
type of Capital Stock Equivalents issuable now or in the future, in connection
therewith and indicating applicable prices and dates or time periods relevant to
any such issuance. To the knowledge of On-Line, each such holder listed on
Schedule 4.7 is the sole beneficial owner of all of the shares or Capital Stock
Equivalents as to which such holder is so listed as the record holder.

                                       12
<PAGE>   14

         On-Line does not have any direct or indirect subsidiaries or any
Affiliates. With respect to On-Line, all such issued and outstanding shares of
capital stock or other Ownership Interests have been duly authorized and validly
issued and are fully paid and nonassessable. None of such shares of capital
stock or other Ownership Interests were issued in contravention of any
preemptive rights. Except as described in Schedule 4.7, there are no Ownership
Interests or other agreements of any character authorized, granted or issued by
On-Line or to which On-Line is a party or by which it is bound which provide for
the purchase, issuance or transfer of any shares of capital stock or any other
security or cash in lieu of any security of On-Line. All voting rights in
On-Line that are presently exercisable or that may be exercised at any time in
the future are vested exclusively in the capital stock listed on Schedule 4.7 or
(as indicated on Schedule 4.7) other Ownership Interests. There are no voting
trusts or other voting arrangements with respect to any voting rights of
On-Line.

         4.8  FINANCIAL STATEMENTS; BOOKS OR RECORDS. On-Line has provided true,
complete and correct copies of the Financial Statements as of August 31, 1995 to
Purchaser. The Financial Statements fairly represent in all material respects
the financial position of On-Line and the related results of operations, and
changes in retained earnings and cash flows, at the dates and for the periods
covered thereby, subject to normal, recurring year-end audit adjustments. The
Financial Statements have been prepared in accordance with GAAP. The Financial
Statements were prepared consistent with past practices, for general use by the
officers and directors of On-Line in the conduct of the ordinary and regular
course of business. As of the Balance Sheet Date, (A) On-Line had no liability
or expense which was not reflected in the Financial Statements and which was of
a nature required under GAAP to be reflected in the Financial Statements or
disclosed in the notes thereto, (B) all allowances and reserves set forth in the
Financial Statements were adequate for the respective purposes for which they
were established, and (C) there were no loss contingencies (as such term is used
in Statement of Financial Accounting Standards No. 5) or contingent liabilities
which were of a nature required under GAAP to be reflected or disclosed therein
and were not reflected in the Financial Statements or disclosed in the notes
thereto and which would have a material adverse effect on the financial
condition or results of operation of On-Line with respect to the On-Line
Business. Since the Balance Sheet Date, except for liabilities that have been
incurred in the ordinary course of the On-Line Business, On-Line has not
incurred any liability required under GAAP to be reflected or disclosed in the
Balance Sheet or disclosed in the notes thereto. Except as set forth in the
Financial Statements, On-Line is not liable upon or with respect to, or
obligated in any other way to provide funds in respect of or to guarantee or
assume in any manner, any debt, obligation or dividend of any Person of a nature
required under GAAP to be reflected or disclosed in the Closing Balance Sheet or
disclosed in the notes thereto. The Financial Statements fairly reflect the
liabilities with respect to the employee benefits payable under the plans,
programs and arrangements set forth in Schedule 4.23(c), consistent with prior
application of the terms of such plans, programs and arrangements and taking
into account performance to date. On-Line has provided to Purchaser, true,
complete and correct copies of all external audit management letters with
respect to On-Line concerning the years and periods covered by the Financial
Statements. Management of On-Line makes and keeps Books and Records with respect
to the On-Line Business which, in reasonable detail, accurately and fairly
reflect in all material respects its transactions and the acquisitions and
dispositions of its assets.

         4.9  INTERCOMPANY TRANSACTIONS. Since the Balance Sheet Date, except as
set forth in Schedule 4.9, all financial liabilities between On-Line, on the one
hand, and any On-Line Stockholder, on the other hand, have been settled in the
ordinary course of the On-Line Business, consistent with past practices. Since
the Balance Sheet Date, all allocations of intercompany expenses between On-Line
and any On-Line Stockholder have been applied, in the ordinary course of the
On-Line Business, consistent with past practices. Schedule 4.9 sets forth all
Contracts between On-Line, on the one hand, and any On-Line Stockholder, on the
other hand. Each of such Contracts which was entered into in the ordinary course
of business, consistent with past practices, and contain only provisions
(including terms and conditions of performance and payment) that are
substantially similar to provisions (including terms and

                                       13
<PAGE>   15

conditions of performance and payment) contained in Contracts entered into with
non-related third parties.

         4.10 ACCOUNTS RECEIVABLE, COLLECTION OF ACCOUNTS RECEIVABLE. All of the
Accounts Receivable of On-Line have arisen in connection with bona fide sales
and deliveries of goods, performance of services or other bona fide business
transactions in the ordinary course of the On-Line Business, consistent with
past practices (including regular credit practices). Except as set forth in
Schedule 4.10, since the Balance Sheet Date, On-Line has not granted or agreed
to provide any rebates, discounts, advances or allowances to any customers which
would result in On-Line being required to provide, subsequent to Closing, any
products or services at discounted rates or free of charge to any customer as a
rebate, discount or advance to any customer to forgive or release, or to collect
or to accelerate the collection of any Accounts Receivable of On-Line.

         4.11 ABSENCE OF CHANGES. Except as set forth in Schedule 4.11, since
the Balance Sheet Date there has not been, occurred or arisen any change in, or
any event (including without limitation any damage, destruction or loss whether
or not covered by insurance), condition or state of facts of any character that
individually or in the aggregate has or may be reasonably expected as of the
date hereof to have a material adverse effect on On-Line or the On-Line
Business. Since the Balance Sheet Date, except as set forth in Schedule 4.11:
(a) On-Line has not taken or failed to take any action the taking of which or
failure of which to take, as the case may be, would have violated any of the
provisions of Sections 10.2 or 10.3 if they had then been applicable to On-Line
during such period; and (b) there has not been any damage, destruction or loss
(whether or not covered by insurance) affecting On-Line, which damage,
destruction or loss individually exceeds $10,000 or the result of which
individually or in the aggregate has or may reasonably be expected to have a
material adverse effect on On-Line or the On-Line Business.

         4.12 INTELLECTUAL PROPERTY AND KNOW-HOW. Schedule 4.12(a) sets forth a
list of all material Intellectual Property utilized by On-Line other than Trade
Secrets and licenses for generally available "shrink-wrapped" commercial
software used on a microcomputer (personal computer) having an acquisition cost
per copy of $1,000 or less. Except as set forth in Schedule 4.12(a), On-Line
owns or has the right to use all Intellectual Property and Know-How utilized by
On-Line and no other Intellectual Property or Know-How is necessary for the
conduct of On-Line Business as presently conducted. The interests of On-Line in
and to all such Intellectual Property is free and clear of any and all Liens or
any other rights of others or other adverse interests, and such Intellectual
Property is not currently being challenged in any way and is not involved in any
pending or, to the knowledge of On-Line, threatened interference or opposition
action or other civil or governmental litigation proceeding or Official Action.
The use by On-Line of its equipment and processes, the use by the customers of
On-Line of its products and services for the purposes for which are sold or
otherwise provided, and the use by On-Line of its Intellectual Property and
advertising, technical or other literature, do not to the knowledge of On-Line,
infringe upon or conflict with any patent, trademark, trade name, Intellectual
Property or other property right of others; and On-Line has not been advised,
nor has any knowledge of the existence of any claim of any such infringement or
conflict. Schedule 4.12(b) sets forth all Consents of third parties (relating to
the Intellectual Property) required as a result of the consummation of the
transactions contemplated by this Agreement. All Know-How that is material to
the On-Line Business is included in the assets of On-Line. On-Line has taken
appropriate measures to protect in all material respects the confidential and
proprietary nature of any material information related to the business strategy,
finances, marketing plans or employees of On-Line which has not been published
and is not generally known to the public.

         4.13 TAXES. (a) Except as disclosed in Schedule 4.13(a), during the
period of any unexpired statutes of limitations (taking into account any waiver
or the like with respect thereto), On-Line has duly filed all federal, foreign,
state and local Tax Returns, reports and estimates for all years and periods
(and portions thereof) for which any such returns, reports or estimates were
due, all such returns and estimates were prepared in the manner required by

                                       14
<PAGE>   16

applicable law, and all Taxes shown thereby to be payable (or that are otherwise
payable) have been paid. No such Tax Return filed contains a disclosure
statement under former Section 6661 (or any replacement provision thereof) of
the Code or any similar provision of any other Legislative Enactment or Official
Action. There is no outstanding request for any extension of time within which
to file any Tax Returns or to pay any taxes. There are no outstanding
agreements, waivers, grants or other arrangements extending the period of
limitations applicable to any claim for, or the period for the collection or
assessment of, any Taxes due from On-Line. On-Line has not taken any action that
would have the effect of deferring any liability for Taxes for On-Line from any
taxable period ending on or before the Effective Date to any taxable period
ending thereafter. On-Line has provided to Purchaser or its representatives
true, complete and correct copies of its federal, state or local Tax Returns
filed for the periods ending September 30, 1989 through September 30, 1994, and
all examination reports, if any, relating to the audit of such returns by the
IRS or other taxing authority for each taxable year beginning on or after
October 1, 1991. The accrued liability for Taxes shown on the Balance Sheets of
On-Line (excluding any reserve for deferred Taxes established to reflect timing
differences between book and tax income) is adequate to cover the liability of
On-Line to the Balance Sheet Date for all Taxes (including all interest and
penalties, if any, thereon and all deficiencies with respect thereto) payable by
On-Line, including with respect to any employee of, or independent contractor
to, On-Line. The accrued liability for Taxes to be shown on the Closing Balance
Sheet (excluding any reserve for deferred Taxes established to reflect timing
differences between book and tax income) is adequate to cover the liability of
On-Line to the Effective Date for all Taxes (including all interest and
penalties, if any, thereon and all deficiencies with respect thereto) payable by
On-Line, including with respect to any employee of, or independent contractor
to, On-Line. There are no Liens for Taxes upon any assets of On-Line except for
statutory Liens in the amounts disclosed on Schedule 4.13, which Liens are for
Taxes or assessments not yet delinquent or the validity of which is being
contested in good faith by appropriate proceedings, as disclosed in Schedule
4.13(a).

         (b) The statute of limitations for the assessment of Taxes has expired
(or all Tax Returns with respect to any such Taxes have been examined by the IRS
or other applicable taxing authority and any liability with respect thereto has
been satisfied) for all periods through 1991 (for federal income taxes) and
through September 30, 1991 (for all other Taxes). Except as disclosed in
Schedule 4.13(b) On-Line has not been audited by the IRS or any other taxing
authority in respect to any Tax year for which the statute of limitations has
not expired. No deficiency for any Taxes has been proposed, asserted or assessed
against On-Line which has not been resolved and paid in full and on a timely
basis. No claim is being made that On-Line is or may be subject to taxation in a
jurisdiction where On-Line does not file Tax Returns nor does On-Line have
knowledge of facts which, upon examination, may reasonably be interpreted to
form the basis of an unasserted claim for Taxes in any such jurisdiction. No
investigations for the assessment or collection of any Taxes, audits or other
administrative proceedings or court proceedings are presently pending or
threatened with regard to any Taxes or Tax Returns. Except as disclosed in
Schedule 4.13(b), there are no requests for rulings, determination letters,
subpoenas or requests for information pending from any taxing authority.

         (c) On-Line is not, nor has it been, a member of an "affiliated group"
(as defined in Section 1504(a) of the Code) filing a consolidated federal income
Tax Return. On-Line has no liability for the Taxes of any other person under
Treasury Regulations Section 1.1502-6 (or any similar provision of any other
Legislative Enactment or Official Action), as a transferee or successor, by
contract, or otherwise. On-Line was not acquired in a "qualified stock purchase"
under Section 338(d)(3) of the Code, and no election under Section 338(g) of the
Code, protective carryover basis election, or offset prohibition election is
applicable to On-Line. Except as may be affected by the transactions
contemplated by this Agreement, as of the Effective Date, the ability of On-Line
to use any Tax attributes (including, without limitation, net operating losses)
will not have been affected by Sections 382, 383 or 384 of the Code or similar
rules or regulations. On-Line has not filed a consent agreement under Section
341(f) of the Code or agreed to have Section 341(f)(2) of the Code apply to any
disposition of the subsection (f) asset (as such term is

                                       15
<PAGE>   17

defined in Section 341(f)(4) of the Code) owned by On-Line. No closing agreement
pursuant to Section 7121 of the Code or any similar provisions of any other
Legislative Enactment or Official Action has been executed or entered into by or
with respect to On-Line.

         (d)  On-Line is not, nor has it been, a party to any tax sharing or
allocation agreement or arrangement pursuant to which it has any contingent or
outstanding liability to any Person. On-Line is not required to include in
income any adjustment pursuant to Section 481(a) of the Code (or similar
provision of law or regulations) by reason of a change in accounting method, nor
is the IRS or any other taxing authority considering any such change in
accounting method. On-Line does not own any interest in an entity which, for
federal income tax purposes, is characterized as a partnership (whether limited
or general) or a limited liability company. On-Line is not a party to any
interest rate swap, currency swap or similar transaction. On-Line has disclosed
on its federal income Tax Returns all positions taken therein that could give
rise to a "substantial understatement" of federal income Tax within the meaning
of Section 6662 of the Code. On-Line has not disposed of any property which has
been accounted for Tax purposes under the installment method. On-Line would not
be liable for any increase in Tax under Section 481 of the Code, were On-Line to
dispose of all of its assets on the Effective Date. On-Line has not issued or
assumed any "corporate acquisition indebtedness" (within the meaning of Section
279(b) of the Code), or any obligation described in Section 279(a)(2) of the
Code. On-Line does not have or maintain a permanent establishment for Tax
purposes in any foreign jurisdiction. No election under Section 1504(d) of the
Code has been made with respect to On-Line. On-Line has not participated in or
cooperated with any international boycott, within the meaning of Section 999 of
the Code. As of the Effective Date, On-Line will not have any (i) "overall
foreign losses" (within the meaning of Section 904(f) of the Code), or (ii)
"non-recapture net Section 1231 losses" (within the meaning of Section 1231(c)

or Business of OHM, which would, if adversely determined, have a material
adverse effect on the Business or financial condition of OHM, taken as a whole.

commercially reasonable efforts to assist On-Line and the Service Corps in
obtaining such Consents.

         10.11 CONFIDENTIAL INFORMATION. Each Selling Entity hereby acknowledges

disclosing, any such confidential or proprietary information, except as
expressly permitted hereunder or under any other agreement between such Selling
Entity and Purchaser. If any Selling Entity is requested or required by any
Tribunal to disclose any of such proprietary or confidential information, then

requirement or waive such Selling Entity's compliance with the provisions of
this Section 10.11 with respect to all or part of such request or requirement.

attempting to obtain any reasonable protective relief that Purchaser chooses to
seek. If, after Purchaser has had a reasonable opportunity to seek such relief,
Purchaser fails to obtain such relief, then such Selling Entity may disclose
only that portion of such proprietary or confidential information which its
legal counsel advises it is compelled to disclose.

         10.12 ENFORCEMENT OF CONFIDENTIALITY AGREEMENT RIGHTS. The Selling
Entities agree to enforce, at the cost and for the benefit of Purchaser, any and
all rights of the Selling Entities under any Contract pursuant to which any
confidential or proprietary information relating to any aspect of On-Line or the
On-Line Business, or the Service Corps or the Business of each Service Corp, was
provided by any Selling Entity to any Person if such Contract is not a part of
the properties of On-Line or the Service Corps. The Selling Entities shall
promptly inform Purchaser of any breach of which they become aware by any Person

confidential or proprietary information relating to On-Line or the On-Line
Business, or the Service Corps or the Business of each Service Corp.

provisions of this Agreement and of the documents referred to herein, and (b)
waives and agrees not to assert, as

                                       41
<PAGE>   43

a defense in any action, suit, or proceeding for the interpretation or
enforcement hereof or of any document referred to herein, that it is not subject
to the jurisdiction of the Courts, or that such action, suit, or proceeding may
not be brought or is not maintainable in the Courts, or that this Agreement or
any of such documents may not be enforced in or by the Courts, or that its
property is exempt or immune from execution, or that the action, suit, or
proceeding is brought in any inconvenient forum, or that the venue of the
action, suit, or proceeding is improper.

         10.16 AFFIRMATIVE COVENANTS OF ON-LINE. Prior to the making of the
distributions called for in Section 10.14, On-Line shall accomplish the
following:

         (a)   enter into a lease or financing arrangement for the Cartridge
Tape Subsystem at a monthly cost not to exceed $5,000; and

         (b)   pay into a reserve account to be maintained by On-Line, such sums
as the Board of Directors of On-Line has determined, for the period ending
September 30, 1995, are to be paid to employees of On-Line: (i) as bonuses
(discretionary or otherwise), or (ii) as contributions (discretionary or
otherwise) of On-Line under any Employee Pension Benefit Plans.

         10.17 CASH SWEEP DEBITS. (a) At Closing and prior to the distributions
called for in Section 10.14, the Agent and Purchaser shall create a joint order
escrow at a mutually agreed upon financial institution, into which On-Line shall
deposit the amount of $65,000 (the "Halon System Escrow"). Such sum shall be
used by Purchaser to offset all losses, costs and expenses of Purchaser, if any
(the "Halon Loss") incurred by Purchaser in connection with a discharge from the
Halon gas fire notification system employed at the Leased Premises (the "Halon
System") which occurs, if at all, prior to October 31, 1996, including costs and
expenses of installation of a water-based system to replace the Halon System. In
the event no such discharge takes place prior to October 31, 1996 (or if such
discharge results in losses, costs or expenses to Purchaser of less than $65,000
prior to October 31, 1996), the Halon System Escrow, or the remaining balance
thereof, as the case may be, shall be paid to the Agent by October 31, 1996.
Purchaser agrees to provide written notice of a Halon Loss to the Agent promptly
upon the occurrence of the event causing such Halon Loss and to supply the Agent
with all documentation evidencing or substantiating such Halon Loss. In the
event of a dispute between the parties with respect to the subject matter of
this Section 10.17(a), the parties agree to submit such dispute to the
alternative dispute resolution process described in Section 15.9.
Notwithstanding the foregoing, if Purchaser renews its lease for the Leased
Premises and replaces the Halon System within a new fire protection notification
system prior to October 31, 1996, Purchaser may use such portion of the proceeds
of the Halon System Escrow as is necessary to offset the costs incurred by
Purchaser in connection with the disposal of the Halon gas used therein. All
sums still held in the Halon System Escrow and not effectively used for the
foregoing (or held pending a claim for the foregoing) shall be paid to the Agent
by December 31, 1996. Purchaser's claims and remedies, if any, against any
On-Line Group member with respect to any matter involving the Halon System,
including without limitation a defect therein or a discharge therefrom, shall be
limited to a claim against funds then held in the Halon System Escrow.

         (b)   To the extent that On-Line has not enhanced its existing ROLM
phone system so as to make it operational under the North American Numbering
Plan (the "ROLM Enhancement"), at Closing and prior to the distributions called
for in Section 10.14, the Agent and Purchaser shall create a joint order escrow
at a mutually agreed upon financial institution, into which On-Line shall
deposit the amount of $35,000 (the "ROLM Escrow"). Such sum shall be used by
Purchaser for the ROLM Enhancement. In the event that Purchaser does not
complete the ROLM Enhancement by January 1, 1996, or the cost to enhance such
system is less than $35,000, the ROLM Escrow, or the remaining balance thereof,
as the case may be, shall be paid to Agent by January 2, 1996. Purchaser agrees
to supply

                                       42
<PAGE>   44

the Agent with all documentation evidencing or substantiating the ROLM
Enhancement and agrees to act in good faith to minimize the cost thereof. In the
event of a dispute between the parties with respect to the subject matter of
this Section 10.17(b), the parties agree to submit such dispute to the
alternative dispute resolution process described in Section 15.9. Purchaser's
claims and remedies, if any, against any On-Line Group member with respect to
any matter involving On-Line's ROLM phone system including without limitation
any defect therein, shall be limited to a claim against funds then held in the
ROLM Escrow.

         (c)   To the extent that On-Line has not adopted and implemented a
Disaster Recovery Plan for the currently existing BankForce product (the "DRP"),
at Closing and prior to the distributions called for in Section 10.14, the Agent
and Purchaser shall create a joint order escrow at a mutually agreed upon
financial institution, into which On-Line shall deposit the amount of $10,000
(the "DRP Escrow"). Such sum shall be used by Purchaser to adopt and implement
the DRP. In the event that Purchaser does not adopt and implement the DRP by
March 31, 1996 or the cost to accomplish same is less than $10,000, the DRP
Escrow, or the remaining balance thereof, as the case may be, shall be paid to
the Agent by April 15, 1996. Purchaser agrees to supply the Agent with all
documentation evidencing or substantiating the DRP and agrees to act in good
faith to minimize the cost thereof. In the event of a dispute between the
parties with respect to the subject matter of this Section 10.17(c), the parties
agree to submit such dispute to the alternative dispute resolution process
described in Section 15.9. Purchaser's claims and remedies, if any, against any
On-Line Group member with respect to any matter involving the DRP shall be
limited to a claim against funds then held in the DRP Escrow.

         (d)   At Closing and prior to the distributions called for in Section
10.14, the Agent and Purchaser shall create a joint order escrow at a mutually
agreed upon financial institution, into which On-Line shall deposit the amount
of $400,000 (the "Audit Escrow"). Such sum shall be used by Purchaser to offset
all losses, costs and expenses of Purchaser, if any (the "Audit Loss") incurred
by Purchaser in connection with a claim by the IRS against On-Line for taxes,
interest and penalties owed by On-Line as a result of the current audit of the
IRS of On-Line's Tax Returns for the fiscal years ending September 30, 1992,
1993 and 1994 (the "Audit Taxes"). The Audit Escrow, or the remaining balance
thereof, as the case may be, shall be paid to Agent by the earlier of (i) the
written acknowledgement of the IRS that On-Line has no continuing liability for
the Audit Taxes, or (ii) June 30, 1998. Purchaser agrees to provide written
notice of an Audit Loss to the Agent promptly upon the occurrence of the event
causing such Audit Loss and to supply the Agent with all documentation
evidencing or substantiating such Audit Loss. Subsequent to the Effective Date,
neither Purchaser nor On-Line shall, with respect to the Audit Taxes, sign any
waivers extending the period of limitations in respect thereof, or make any
settlement or compromise of the Audit Taxes without Agent's prior written
consent, which consent shall not be unreasonably withheld. In the event of a
dispute between the parties with respect to the subject matter of this Section
10.17(d), the parties agree to submit such dispute to the alternative dispute
resolution process described in Section 15.9. Purchaser's claims and remedies,
if any, against any On-Line Group member with respect to any matter involving
the Audit Taxes shall be limited to a claim against funds then held in the Audit
Escrow.

         (e)   The escrows contemplated by Sections 10.17(a) through (d) may be
maintained at the same financial institution and held by the escrowee(s)
thereunder in one account provided separate accounting is maintained for each of
the above-described escrows. The escrows shall provide that all interest and
earnings thereon shall be paid to the Agent on an annual basis. The cost of any
escrow shall be satisfied from the earnings thereon and if insufficient, then
from the principal thereof.

         10.18 OFFSETS TO CONTINGENT PAYMENT. (a) Purchaser shall be entitled to
offset against the Asset Notes and the Contingent Payment all losses, costs and
expenses of Purchaser, if any (the "SD Loss"), incurred by Purchaser in

                                       43
<PAGE>   45

connection with a claim by the State of South Dakota against On-Line for taxes,
interest and penalties owed by On-Line for all periods prior to Closing (the "SD
Taxes"). Purchaser agrees to provide written notice of an SD Loss to the Agent
promptly upon the occurrence of the event causing such SD Loss. No offset
hereunder shall be made without thirty (30) business days' prior written notice
to the Agent, which notice shall state the nature of the items comprising the
offset and shall include copies of all documents evidencing same. Subsequent to
the Effective Date, neither Purchaser nor On-Line shall, with respect to the SD
Taxes, sign any waivers extending the period of limitations in respect thereof,
or make any settlement or compromise of the SD Taxes without Agent's prior
written consent, which consent shall not be unreasonably withheld. In the event
of a dispute between the parties with respect to the subject matter of this
Section 10.18(a), the parties agree to submit such dispute to the alternative
dispute resolution process described in Section 15.9. Any such offset shall be
made first against the Asset Notes and then against the Contingent Payment.
Purchaser's claims and remedies, if any, against any On-Line Group member with
respect to any matter involving the SD Taxes shall be limited to a claim against
the Asset Notes and the Contingent Payment.

         (b) Purchaser shall be entitled to offset against the Asset Notes and
the Contingent Payment all losses, costs and expenses of Purchaser, if any (the
"Tax Loss"), incurred by Purchaser in connection with a claim by the City of
Chicago against On-Line for taxes, interest and penalties arising under the
Chicago Personal Property Lease Transaction Tax Ordinance, Chapter 3-32 of the
City of Chicago Municipal Code (the "Chicago Taxes") for all periods prior to
Closing. Purchaser agrees to provide written notice of a Tax Loss to the Agent
promptly upon the occurrence of the event causing such Tax Loss. No offset
hereunder shall be made without thirty (30) business days' prior written notice
to the Agent, which notice shall state the nature of the items comprising the
offset and shall include copies of all documents evidencing same. Subsequent to
the Effective Date, neither Purchaser nor On-Line shall, with respect to the
Chicago Taxes, sign any waivers extending the period of limitations in respect
thereof, or make any settlement or compromise of the Chicago Taxes without
Agent's prior written consent, which consent shall not be unreasonably withheld.
In the event of a dispute between the parties with respect to the subject matter
of this Section 10.18(b), the parties agree to submit such dispute to the
alternative dispute resolution process described in Section 15.9. Any such
offset shall be made first against the Asset Notes and then against the
Contingent Payment. Purchaser's claims and remedies, if any, against any On-Line
Group member with respect to any matter involving the Chicago Taxes shall be
limited to a claim against the Asset Notes and the Contingent Payment.

                             COVENANTS OF PURCHASER

         11.1 CONSUMMATION OF TRANSACTIONS. Subject to the terms and conditions
herein provided, from the date hereof through the Effective Date, Purchaser will
use its best efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary, proper or advisable to consummate and
make effective, as promptly as practicable, the transactions contemplated by
this Agreement in accordance with the terms of this Agreement applicable to
Purchaser. From the date hereof through the Effective Date, Purchaser shall not
voluntarily take any action or course of action inconsistent with the
satisfaction of the respective conditions, terms and provisions of this
Agreement or the consummation of the respective transactions contemplated by
this Agreement in accordance with the terms of this Agreement applicable to
Purchaser.

         11.2 NOTIFICATION OF CERTAIN MATTERS. Prior to the Effective Date,
Purchaser shall give prompt notice to the Agent of: (a) any threatened or actual
lawsuit, any proposed settlement of any threatened or actual lawsuit and any
pending or threatened governmental action or proceeding of any kind known to
Purchaser which relates to the transactions then contemplated by this Agreement;
and (b) any material failure of Purchaser or any officer, director, employee or
agent thereof, to comply with or satisfy any covenant, condition or agreement
then remaining to be complied with or satisfied by it hereunder.

         11.3 PERSONNEL. On-Line has not made and, without obtaining the prior
written consent of Purchaser, shall not make any representation, promise or
other communication, whether written or oral, to its employees regarding
employment with Purchaser or the employment benefits, plans or practices of
Purchaser.

         11.4 CONFIDENTIAL INFORMATION. Purchaser hereby acknowledges that the
On-Line Group would be irreparably damaged if any proprietary or confidential
information possessed by On-Line, the Service Corps, Purchaser or any Affiliate
of Purchaser, concerning any member of the On-Line Group (except for any
information that is or becomes generally known to the public, otherwise than
through a breach of this Agreement) were disclosed to or used by any Person
engaged in competition with any member of the On-Line Group. For a period of
five years from and after the Effective Date, Purchaser agrees that it will not
use or disclose any such confidential or proprietary information, except as
expressly permitted hereunder or under any other agreement between such On-Line
Group member and Purchaser or any of its Affiliates. If Purchaser is requested
or required by any Tribunal to disclose any of such proprietary or confidential
information, then Purchaser will provide the Agent with prompt written notice of
such request or requirement unless prohibited by law. The Agent may then either
seek appropriate protective relief from all or part of such request or
requirement or waive Purchaser's compliance with the provisions of this Section
11.4 with respect to all or part of such request or requirement. Purchaser will
cooperate with the Agent at the Agent's expense, in attempting to obtain any
reasonable protective relief that the Agent chooses to seek. If, after the Agent
has had a reasonable opportunity to seek such relief, the Agent fails to obtain
such relief, then Purchaser may disclose only that portion of such proprietary
or confidential information which its legal counsel advises it is compelled to
disclose. Nothing herein contained shall be construed so as to limit or
otherwise diminish any obligations of confidentiality owed to customers of
On-Line pursuant to any agreements involving On-Line and its customers.

         11.5 ASSISTANCE AND COOPERATION. After the Effective Date, at the
Selling Entities' expense, Purchaser agrees:

         (a) to assist the Selling Entities in preparing the Closing Balance
Sheet;

                                       45
<PAGE>   47

         (b)  to provide timely notice to the Agent in writing of any pending or
threatened tax audits or assessments related to the On-Line Business or On-Line
or the Service Corps or the Business of each Service Corp, for periods beginning
prior to the Closing and of which Purchaser has knowledge and to furnish such
Selling Entities with copies of all correspondence received from any Tribunal in
connection with any tax audit or information request with respect to any such
period; and

         (c)  to provide access, upon reasonable notice during normal business
hours, to the Agent or any other authorized representatives of the Selling
Entities, to the Books and Records of On-Line and the Service Corps, and such
Books and Records of Purchaser and its Affiliates as the Selling Entities shall
determine in their sole but reasonable discretion are necessary to determine
and/or verify the accuracy of the payments and contingent payments due the
Selling Entities hereunder.

         11.6 MISCELLANEOUS DISTRIBUTIONS. Provided same have not been assigned
in their entirety to the Agent as provided in Section 10.7 hereof, within 90
days of the end of each of the first four fiscal quarters of On-Line ending
after the Effective Date, Purchaser will pay to the Agent all sums received by
On-Line (and the Service Corps) that are payments upon Accounts Receivable of
On-Line and the Service Corps in existence prior to the Effective Date that are
not related to prepayment for services to be performed after the Effective Date
("Effective Date Accounts Receivable"), net of: (a) the third party costs of
collecting any of Effective Date Accounts Receivable, and (b) the third party
costs of any claims or disputes with respect to the Effective Date Accounts
Receivable or to the services or goods to which they relate.

         11.7 TAX ELECTION. Purchaser will not, in connection with any of the
transactions contemplated by this Agreement, make an election under Section 338
of the Code.

                                 INDEMNIFICATION

         14.1  INDEMNIFICATION BY PURCHASER. Purchaser and each of them, jointly
and severally, agrees to indemnify and hold harmless each Selling Entity and its
respective directors, officers, employees, advisors, Affiliates, agents and
representatives, stockholders, successors and assigns ("SE Indemnities") from
and against any and all losses, damages, liabilities, claims, costs, fees and
expenses, including without limitation Legal Expenses (collectively, "Losses")
arising out of, based upon or resulting from: (a) any violation or breach by
Purchaser of, or any default by Purchaser under, this Agreement or any
certificate, Schedule, Exhibit or other document or instrument furnished or to
be furnished by Purchaser to any Selling Entity pursuant to and as described in
this Agreement or any agreement contemplated hereby or the consummation of the
transactions contemplated hereby or thereby, or (b) any error, inaccuracy or
misrepresentation in any of the representations and warranties made by, or on
behalf of, Purchaser herein or therein, or (c) any violation or breach of the
WARN Act which arises subsequent to Closing, or (d) any suit or action at law or
in equity, any arbitration or alternative dispute resolution proceeding, any
interference or opposition proceeding, any governmental or quasi-governmental
proceeding, complaint, or investigation, or any liability claim which arises in
connection with, or relates to, any of the matters referred to in clause (a),
(b) or (c) of this Section 14.1. The foregoing obligations of Purchaser with
respect to any error, inaccuracy or misrepresentation in any particular
representation and warranty made by, or on behalf of, Purchaser shall terminate
on the Expiration Date (as defined in Section 15.1) applicable to such
representation and warranty (except that such obligations shall thereafter
continue in full force and effect with respect to any Losses of which Purchaser
has received a Request (as defined in Section 14.3) or written notice of a claim
or action for loss or damage made by an unaffiliated Person (a "Third-Party
Matter") prior to the Expiration Date). Notwithstanding the foregoing provisions
of this Section 14.1, with respect to any Losses ("SE Losses") arising out of,
based upon or resulting from any error, inaccuracy or misrepresentation in any
of the representations and warranties contained in Article III or in any of the
representations and warranties (but not covenants) of Purchaser contained in any
certificate, document, affidavit or instrument delivered pursuant to this
Agreement: (a) the foregoing indemnity and hold harmless obligations of
Purchaser relating to such SE Losses shall become operative and effective only
if and when all SE Losses for which SE Indemnities are entitled to receive
indemnification under this Section 14.1 exceed, in the aggregate, $10,000 (it
being understood and agreed that all such SE Losses shall accumulate until such
time as they exceed $10,000, at which time Purchaser shall be obligated to
indemnify any SE Indemnities seeking indemnification under this Section 14.1 for
the amount that such SE Losses, in the aggregate, exceed $10,000), and (b) with
respect to the foregoing indemnity and hold harmless obligations of Purchaser
relating to the SE Losses, the liability of Purchaser to indemnify and hold
harmless the SE Indemnities for all SE Losses under this Section 14.1 shall not
exceed, in the aggregate, the Purchase Price.

         14.2  INDEMNIFICATION BY SELLING ENTITIES. The Selling Entities,
individually and not jointly and severally, agree to indemnify and hold harmless
Purchaser and its directors, officers, employees, advisors, Affiliates, agents,
representatives, stockholders, successors and assigns ("Purchaser Indemnities")
from and against any and all Losses

                                       49
<PAGE>   51

arising out of, based upon or resulting from: (a) any violation or breach by
On-Line, a Service Corp or any Selling Entity of, or default by On-Line, a
Service Corp or any Selling Entity under, this Agreement or any certificate or
other document or instrument furnished or to be furnished by On-Line, a Service
Corp or any Selling Entity to Purchaser pursuant to and as described in this
Agreement or any agreement contemplated hereby or the consummation of the
transactions contemplated hereby or thereby, or (b) any error, inaccuracy or
misrepresentation in any of the representations and warranties made by, or on
behalf of On-Line, a Service Corp or any Selling Entity herein or therein, or
(c) any violation or breach of the WARN Act not indemnified by Section 14.1
which arises prior to Closing, or (d) any liability or obligation arising out of
payment of any part of the Purchase Price to the Agent as agent for any Selling
Entity, or (e) any suit or action at law or in equity, any arbitration or
alternative dispute resolution proceeding, any interference or opposition
proceeding, any governmental or quasi-governmental proceeding, complaint, or
investigation, or any liability claim which arises in connection with, or
relates to, any of the matters referred to in clause (a), (b), (c) or (d) of
this Section 14.2. The foregoing obligations of the Selling Entities with
respect to any error, inaccuracy or misrepresentation in any particular
representation and warranty made by, or on behalf of, any Selling Entity shall
terminate on the Expiration Date applicable to such representation and warranty
(except that such obligations shall thereafter continue in full force and effect
with respect to any Losses of which the Agent has received a Request or written
notice of a Third-Party Matter prior to the Expiration Date). Notwithstanding
the foregoing provisions of this Section 14.2, with respect to any Losses
("Purchaser Losses") arising out of, based upon or resulting from any error,
inaccuracy or misrepresentation in any of the representations and warranties
contained in Articles IV through IX or in any of the representations and
warranties (but not covenants) of On-Line, a Service Corp or any Selling Entity
contained in any certificate, document, affidavit or instrument delivered
pursuant to this Agreement: (a) the foregoing indemnity and hold harmless
obligations of Purchaser relating to such Purchaser Losses shall become
operative and effective only if and when all Purchaser Losses for which
Purchaser Indemnities are entitled to receive indemnification under this Section
14.2 exceed, in the aggregate, $10,000 (it being understood and agreed that all
such Purchaser Losses shall accumulate until such time as they exceed $10,000,
at which time the Selling Entities shall be obligated to indemnify any Purchaser
Indemnities seeking indemnification under this Section 14.2 for the amount that
such Purchaser Losses, in the aggregate, exceed $10,000), and (b) with respect
to the foregoing indemnity and hold harmless obligations of the Selling Entities
relating to the Purchaser Losses, the liability of the Selling Entities to
indemnify and hold harmless the Purchaser Indemnities for all Purchaser Losses
under this Section 14.2 shall not exceed, in the aggregate, the sum of the Asset
Notes and the Contingent Payment (collectively the "Deferred Payment").
Notwithstanding any other provision of this Agreement, the aggregate
indemnification liability of the Selling Entities shall be limited to the
aggregate amount of the Deferred Payment theretofore paid or thereafter payable
to such Selling Entity, and the amount of any Purchaser Losses at any time then
payable shall be limited to the aggregate amount of the Deferred Payment
theretofore paid or payable, with the balance of such Purchaser Losses
thereafter payable when and as additional amounts of the Deferred Payment are
paid or payable. The aggregate indemnification liability of the Selling Entities
shall be further limited such that a Selling Entity shall not be responsible for
a breach of a representation or warranty made by a Service Corp under Articles
VI, VII and XIII unless such Selling Entity is a stockholder of such breaching
Service Corp. By way of example and not as a limitation, a breach by ISC of its
representations and warranties under Article VI will not result in any
indemnification liability to Superior, the SLI Stockholders or the OHM
Stockholders, but rather, Purchaser's right to indemnification shall be limited
to that portion of the Deferred Payment allocated to the ISC Stockholders under
Section 2.2(a). Nothing herein contained shall be construed so as to limit the
liability of any Selling Entity for a breach by such Selling Entity of its
representations and warranties made under Article V (as to Superior) or under
Article IX (as to the Thrifts).

         14.3  SATISFACTION OF CLAIMS. If any Person entitled to indemnification
under this Article XIV (an "Indemnified Party") desires to assert any claim for
indemnification or to be held harmless under this Article XIV (a "Claim"), the
Indemnified Party shall deliver to the Person that is obligated to provide such
indemnification (the

                                       50
<PAGE>   52

"Indemnifying Party") notice of its demand for satisfaction of such Claim (a
"Request"), specifying in reasonable detail the amount of such Claim and, to the
extent practicable under the circumstances, the basis for asserting such Claim.
Within 20 Business Days after the Indemnifying Party has been given a Request,
the Indemnifying Party shall either: (a) satisfy the Claim requested to be
satisfied in such Request by delivering to the Indemnified Party payment by wire
transfer or a certified or bank cashier's check payable to the Indemnified Party
in immediately available Federal Reserve Funds in an amount equal to the amount
of such Claim, or (b) notify the Indemnified Party that the Indemnifying Party
contests such Claim by: (i) delivering to the Indemnified Party an objection to
such Claim, specifying in reasonable detail, to the extent practicable under the
circumstances, the basis for contesting such Claim, and (ii) demanding
alternative dispute resolution of the Claim in accordance with Section 15.9. In
the case of any Selling Entity, notice to the Agent shall be sufficient for all
purposes.

         14.4  MATTERS WHICH MAY GIVE RISE TO CLAIMS. (A) NOTICE AND CONTROL.
Promptly after receipt by an Indemnified Party of notice of the commencement of
any action, such Indemnified Party will, if a Claim in respect thereof is to be
made against the Indemnifying Party under this Article XIV, notify the
Indemnifying Party of the commencement thereof; but the omission so to notify
the Indemnifying Party will not relieve it from any liability which it may have
to any Indemnified Party otherwise than under this Article XIV. In case any such
action is brought against any Indemnified Party and it notifies the Indemnifying
Party of the commencement thereof, the Indemnifying Party will be entitled to
participate therein, with counsel satisfactory to such Indemnified Party. The
Indemnified Party shall have the right, but shall not have any duty or
obligation, to undertake and contest any Third-Party Matter in such manner as it
may deem appropriate, at the cost and expense of the Indemnifying Party. An
Indemnifying Party shall not be liable for any settlement of any such action or
proceeding effected without its written consent (which shall not be unreasonably
withheld), but if any such action or proceeding is settled with its written
consent, or if there is a final judgment for the plaintiff in any such action or
proceeding, the Indemnifying Party shall indemnify and hold harmless such
Indemnified Party from and against any loss or liability (to the extent stated
above) by reason of such settlement or judgment. In the case of any Selling
Entity, notice to the Agent shall be sufficient for all purposes.

         (B)   EXPENSES. If the Indemnified Party undertakes the defense,
compromise and settlement of such Third-Party Matter pursuant to Section
14.4(a), the Indemnifying Party will promptly reimburse the Indemnified Party
for all reasonable fees, costs and expenses (including without limitation any
Legal Expenses) incurred by the Indemnified Party in respect of such Third-Party
Matter. The reimbursement of such fees, costs and expenses shall be made by
periodic payments during the course of any investigation or defense, as and when
bills are received or expenses incurred.

         (C)   COOPERATION. The Indemnified Party and the Indemnifying Party
shall cooperate in the defense of a Third Party Matter that is defended in
accordance with this Section 14.4, and shall make available to the defending,
person or its representative all records and materials required for its use in
such defense.

                                   ARTICLE XV
                                     GENERAL

         15.1  SURVIVAL OF REPRESENTATIONS AND AGREEMENTS. All representations
and warranties contained in this Agreement or in any certificate, document,
affidavit or instrument delivered pursuant to this Agreement shall survive the
Closing, the consummation of the transactions contemplated hereby and any
investigation made at any time by or on behalf of any of the parties and shall
continue in full force and effect: (a) until the expiration of the applicable
statute

                                       51
<PAGE>   53

of limitations in the case of the representations and warranties set forth in
Sections 4.13, 6.8, 7.8 and 8.8; (b) until the earlier of the expiration of the
seven-year period following the Effective Date or payment in full of the
Purchase Price, in the case of all other representations and warranties of an
On-Line Group member or Purchaser; and (c) for the comparable periods of time
set forth above in this Section 15.1 in the case of each representation and
warranty (but not any covenant) set forth in any certificate, document,
affidavit or instrument delivered pursuant to this Agreement, based upon the
nature of such representation and warranty when compared to the most analogous
representation and warranty set forth above. The date of the expiration of the
applicable time period referenced above for any particular representation and
warranty is hereinafter referred to as the "Expiration Date." Covenants and
agreements set forth in this Agreement to be performed after the Effective Date
will survive the Effective Date in accordance with their respective terms. All
representations, warranties, covenants and agreements made or contained in this
Agreement or in any certificate, document, affidavit or instrument delivered in
accordance with this Agreement shall be deemed to be material to the extent so
provided and to have been relied upon by the parties hereto, notwithstanding any
investigation heretofore or hereafter made by the parties hereto or on their
behalf before the Closing.

         15.2 TERMINATION. This Agreement may be terminated at any time prior to
the Closing: (a) by the mutual consent in writing of Purchaser and the Agent; or
(b) by Purchaser or the Agent if any court of competent jurisdiction in the
United States or other United States Tribunal shall have issued an Official
Action or taken any other action resting, enjoining or otherwise prohibiting any
part of the transactions contemplated by this Agreement, and such order, decree,
ruling or other action shall have become final. If for any reason whatsoever the
Closing shall not have taken place on or before October 30, 1995; the Agent
shall have the right and the authority, on behalf of the Selling Entities, to
terminate this Agreement upon notice given to Purchaser at any time prior to
such Closing.

         15.3 EXPENSES OF TRANSACTION; FINDERS' FEES. Each party shall be
responsible for its own costs associated with the negotiation and consummation
of the transactions contemplated hereby, including without limitation all legal,
consulting and accounting expenses and any fees or commissions due any broker as
a consequence of the consummation of such transactions. Each of the parties
hereto is responsible for, and shall indemnify the other against, any claim by
any third party to a fee, commission or other remuneration arising by reason of
any services alleged to have been rendered to or at the instance of said party
with respect to this Agreement or any of the transactions contemplated hereby.

         15.4 PUBLIC DISCLOSURE. No party shall issue any press release or
otherwise make any public statement with respect to the transactions
contemplated hereby, except with the prior written consent of the other party;
provided, however, that such consent shall not be required either for any
announcement intended solely for internal distribution by Purchaser or the
Selling Entities to their employees or for any

                                       52
<PAGE>   54

disclosure or reporting obligations of any party, to the extent required by
applicable Legislative Enactments or other competent authority, but (as is
practicable under the circumstances) such disclosing party shall consult with
the other party in advance.

benefit of the parties and their respective successors and permitted assigns.
Purchaser may not assign any right under this Agreement or delegate any
obligations hereunder without the express prior written consent of the Agent,
except to an Affiliate of Purchaser; provided, however, that any such delegation
of obligations hereunder to an Affiliate of Purchaser shall not relieve
Purchaser of any of its obligations under this Agreement. No Selling Entity may
assign any rights under this Agreement or delegate any obligations hereunder
without the express prior written consent of Purchaser.

         15.7 AMENDMENTS, WAIVERS, ETC. This Agreement may not be modified or
amended except by a written instrument executed by or on behalf of each of the
parties to this Agreement. The observance of any term of this Agreement may be
waived (either generally or in a particular instance and either retroactively or
prospectively) by the party entitled to enforce such term, but such waiver shall
be effective only if it is in writing signed by the party against which such
waiver is to be asserted. The Agent may act in the name of, for, and on behalf
of any Selling Entity. Unless otherwise expressly provided in this Agreement, no
delay or omission on the part of any party in exercising any right or privilege
under this Agreement shall operate as a waiver thereof, nor shall any waiver on
the part of any party of any right or privilege under this Agreement operate as
a waiver of any other right or privilege under this Agreement nor shall any
single or partial exercise of any right or privilege preclude any other or
further exercise thereof or the exercise of any other right or privilege under
this Agreement.

         15.8 GOVERNING LAW. Notwithstanding the place where this Agreement may
be executed by any of the parties hereto, the parties expressly agree that all
the terms and provisions hereof shall be governed by, and interpreted and
construed in accordance with, the substantive laws of the State of Illinois,
without giving effect to principles relating to conflicts of laws.

         15.9 DISPUTE RESOLUTION. In the event of any dispute, controversy or
claim of any kind or nature arising under or in connection with this Agreement
or any other agreement contemplated hereby that the parties are unable to
resolve through informal discussions or negotiations, the parties agree to
submit such dispute, controversy or claim to alternative dispute resolution in
accordance with the procedures set forth on Exhibit E.

<PAGE>   55

         15.10 NUMBER AND GENDER. Unless the context otherwise requires, the
singular and plural forms in this Agreement shall be mutually inclusive, and the
masculine, feminine and neuter forms in this Agreement shall be mutually
inclusive.

         15.11 SECTION HEADINGS, SCHEDULES, ETC. The cover page and table of
contents preceding this Agreement and the headings of the various sections of
this Agreement and of the Schedules hereof and Exhibits hereto are for
convenience of reference only and do not, and shall not be deemed to, modify,
define, expand or limit any of the terms or provisions hereof. Any item
referenced in a Schedule hereto is deemed to be disclosed only with respect to
the specific Section number of this Agreement which is explicitly referenced in
such Schedule. The absence of any Schedule hereto, the purpose of which is to
set forth exceptions or other qualifications to the representations and
warranties hereunder, shall be deemed to state that no such exceptions or
qualifications exist.

         15.12 COMPLETE AGREEMENT; COUNTERPARTS. This document and the documents
(including Exhibits and Schedules) delivered pursuant hereto, contain the
complete agreement and understanding of the parties hereto and thereto with
respect to the matters covered hereby and thereby, and they rescind and
supersede any prior agreements and understandings which may have in any way
related to the subject matter hereof and thereof. The express terms hereof
control and supersede any course of performance or usage of the trade
inconsistent with any of the terms hereof. This Agreement may be executed by the
parties hereto in several counterparts, and, when so executed and delivered,
shall be an original as against any party whose signature appears thereon, but
all such counterparts shall together constitute but one and the same instrument.
Each counterpart may consist of a number of copies hereof each executed by less
than all, but together executed by all, of the parties hereto. This Agreement
shall become binding when one or more counterparts hereof, individually or taken
together, shall bear the signatures of all of the parties reflected hereon as
the signatories. It shall not be necessary in making proof of this Agreement to
produce or account for more than one such counterpart.

         15.13 SEVERABILITY. If any provision of this Agreement or the
application of any such provision to any Person or circumstance, shall be
declared judicially to be invalid, unenforceable or void, such decision shall
not have the effect of invalidating or voiding the remainder of this Agreement,
it being the intent and agreement of the parties that this Agreement shall be
deemed amended by modifying such provision to the extent necessary to render it
valid, legal and enforceable while preserving its intent or, if such
modification is not possible, by substituting therefor another provision that is
legal and enforceable and that achieves the same objective.

         15.14 NO THIRD PARTY BENEFICIARIES. Nothing in this Agreement is
intended or shall be construed to give any Person, other than the parties
hereto, any legal or equitable right, remedy or claim under or in respect of
this Agreement or any provision contained herein.

                           NEGOTIABLE PROMISSORY NOTE

         FOR VALUE RECEIVED, OLF ACQUISITION CORP., an Illinois corporation, and
ARGO BANCORP, INC., a Delaware corporation (collectively "Maker") hereby,
jointly and severally, promise to pay to the order of MIDWEST TRUST SERVICES,
INC., an Illinois corporation (the "Agent"), the amount of
___________________________________ ($____________) [the "Asset Amount"], with
interest on the unpaid balance thereof from the date of this Note until paid at
the rate of ___% per annum [the interest rate to be fixed at Closing at the
simple interest rate equal to the higher of (A) the Applicable Federal Rate, or
(B) the rate currently bid for the most recently auctioned two (2)-year Treasury
bills as reported in The Wallstreet Journal]. Said principal shall be payable
when and as described in that certain Stock Purchase Agreement dated as of
September 21, 1995, by and among On-Line Financial Services, Inc., the Service
Corps and the Selling Entities specified therein, and Maker (the "Agreement"),
with a final payment (the "Balloon Note Payment") of the entire unpaid balance
of such principal being due and payable on the second anniversary of the
Effective Date (as defined in the Agreement). Said interest shall be payable on
the same dates as said principal is payable.

         This promissory note (this "Note") is issued under and pursuant to the
Agreement. Capitalized terms not otherwise defined in this Note shall have the
respective meanings ascribed thereto in the Agreement.

         With respect to this Note, Maker, the Selling Entities and the Agent
shall be entitled to the benefits of the Agreement and shall also be subject to
the obligations and other burdens of the Agreement.

         Payments hereunder shall be timely made when deposited in the United
States mail, postage prepaid, addressed to the Agent at 1606 N. Harlem Avenue,
Elmwood Park, Illinois 60635 (or such other address as the Agent may from time
to time specify in writing to Maker by a notice in accordance with the
Agreement). This Note may, at the option of the Maker be prepaid in whole or in
part, in the minimum denomination of $10,000 or an integral multiple thereof,
without premium, at any time or from time to time. Each prepayment of principal
shall be made together with interest accrued thereon to the date of such
prepayment.

         All payments of principal and of interest on this Note shall be made in
coin or currency of the United Sates which, at the time of payment, is legal
tender for the payment of public and private debts, and shall be made by
delivery to the Agent of a United States dollar check issued by a federally

         This promissory note (this "Note") is issued under and pursuant to that
certain Stock Purchase Agreement dated as of September 21, 1995, by and among

the obligations and other burdens of the Agreement.

         Payments hereunder shall be timely made when deposited in the United

regulation to close, such payment need not be made on such due date but may be
deferred to the next succeeding day which is not a Saturday, a Sunday, a legal
holiday in the United States or the State of Illinois, or a day on which banks
in Chicago, Illinois, are authorized or obligated by law, rule or regulation to
close; provided, however, that interest on this Note shall continue to accrue

shall impair any such right or power or shall be construed to be a waiver of any
such default or any acquiescence therein. No waiver of any default shall be

further or succeeding default of the same nature. Any subsequent holder of this

                           DISPUTE RESOLUTION PROCESS

         (a) Either the Agent or Purchaser may demand arbitration by giving the
other party written notice to such effect, which notice will (A) describe, in
reasonable detail, the nature of the dispute, controversy or claim, the amount,
if any, involved and the remedy sought, and (B) name an independent arbitrator
employed by Endispute, Inc., who is experienced in the resolution of disputes,
controversies or claims of such a nature. In addition, such party demanding
arbitration shall take such steps as are necessary to commence arbitration
proceedings under the rules of the American Arbitration Association (including,
without limitation, the payment of any administrative fees provided thereunder).

         (b) Within 30 days after the other party's receipt of such demand, such
other party will name a second independent arbitrator, also employed by
Endispute, Inc., who is experienced in the resolution of disputes, controversies
or claims of such a nature.

         (c) The two arbitrators so named will promptly select a third neutral
arbitrator, also employed by Endispute, Inc., who is experienced in the
resolution of disputes, controversies and claims of such a nature. The
arbitration will be heard by a panel of the three arbitrators so chosen (the
"Arbitration Panel") in Chicago, Illinois, and the resolution of the dispute,
controversy or claim will be determined by a majority vote of the Arbitration
Panel. The Commercial Arbitration Rules of the American Arbitration Association
will govern the conduct of the arbitration and the selection of the arbitrators.

         (d) The Arbitration Panel may apportion between the parties as the
Arbitration Panel may deem equitable the fees, costs and expenses of the
arbitration incurred by the parties. The Arbitration Panel may also award
interest on any awards made by the Arbitration Panel. In the assessment of any
award of interest, the Arbitration Panel shall consider any delay in the
satisfaction of claims by the indemnifying party.

         (e) The party demanding arbitration will request the Arbitration Panel
to (A) allow for the parties to request reasonable discovery pursuant to the
rules then in effect under the Federal Rules of Civil Procedure for a period not
to exceed 60 days prior to such arbitration (all with the stated intent of
establishing a fair, speedy and cost-effective dispute resolution mechanism),
and (B) require the testimony to be transcribed. No findings of fact or opinions
of law will be required to be made by the arbitrators.

         (f) Any award rendered by the Arbitration Panel will be final,
conclusive and binding upon the parties, and any judgment thereon may be entered
and enforced in any court of competent jurisdiction.

         Other than actions for temporary and permanent injunctive relief or
specific performance or any action necessary to enforce the award of the
Arbitration Panel, the provisions of Section 15.9 (which includes this Exhibit
E) will constitute the exclusive remedy of the parties and a complete defense to
any suit, action or other proceeding instituted in any court or before any other
Tribunal with respect to any dispute, controversy or claim arising under or in
connection with this Agreement or the other agreements contemplated hereby.
Notwithstanding any other provision in Section 15.9 (which includes this Exhibit
E) to the contrary, the Arbitration Panel will not have the authority to amend
the provisions of Section 15.9 (which includes this Exhibit E) without obtaining
the prior written consent of each of the parties to this Agreement.

agree to provide Purchaser and Purchaser DP separate financial information and
data relative to the Branch Office, including but not limited to (to the extent
available) separate general ledger and trial balance reports together with all
other daily reporting to the Branch Office as reasonably requested by Purchaser
and/or Purchaser DP until the completion of the Data Processing Conversion as
more fully described in Paragraph 4.7(i). Seller and OLFSI shall covenant to
cooperate with Purchaser and Purchaser DP in all matters during the account
transition period and the Data Processing Conversion process.

                                   ARTICLE VII

                    ACTIONS RESPECTING EMPLOYEES AND PENSIONS
                           AND EMPLOYEE BENEFIT PLANS.

         7.1  EMPLOYMENT OF EMPLOYEES.

              (a)  Purchaser shall extend offers of employment, as of the
Closing Date, to such employees of the Branch Office listed in Schedule 7.1(a)
attached hereto and incorporated herein, which schedule shall include the names
of each employee, their date of employment, salary, type of health plan
coverage, including single or family coverage, number of dependents and portion
of premium paid by employee, and any applicable severance plan as may be
employed by Seller at the Branch Office as of the Closing Date (including,
without limitation, those employees who on the Closing Date are on family and
medical leave, military leave, or personal or pregnancy leave and who

                                       15

<PAGE>   16

elect to return to work not later than one (1) year following the Closing Date;
individually and collectively the "Leave Employees" herein) for positions
entailing responsibilities in effect at Seller as of the Closing Date, and for a
base salary not less than that paid by Seller as of the Closing Date. Employees
accepting employment with Purchaser, including but not limited to the Leave
Employees, are referred to herein individually and collectively as the
"Transferred Employees." In the event that Purchaser shall transfer (except in a
comparable position and for comparable compensation to an office not more than
35 miles from the Branch Office at which the Transferred Employee is employed as
of the Closing Date, or at the request of the Transferred Employee), terminate
employment of, or reduce the base salary of, a Transferred Employee (the
"Terminated Employee") between the Closing Date and the date which is one (1)
year from the Closing Date, other than for cause, Purchaser shall pay to the
Terminated Employee a sum equal to the greater of that which the Terminated
Employee would have received on the date of such transfer, termination, or
reduction in salary under the severance plan of Seller applicable to the
Terminated Employee as of the date hereof and set forth in Schedule 7.1 or the
severance plan of Purchaser otherwise applicable to the Terminated Employee as
of the date of such transfer, termination, or reduction in base salary. Such
payment shall be due and owing the Terminated Employee on the date of such
transfer, termination, or reduction in salary. Nothing contained in this
Agreement shall restrict or prohibit Purchaser and any Transferred Employee from
entering into an agreement satisfactory to both Purchaser and the Transferred
Employee providing for resolution of matters set forth in this section.

              (b)  Seller will cooperate with Purchaser, to the extent
reasonably requested and legally permissible, to provide Purchaser with
information about the employees of the Branch Office including, without
limitation, providing Purchaser with the personnel files of those employees of
the Branch Office who provide Seller with their written consent thereto, and a
means to meet with the subject employees. Purchaser hereby agrees to indemnify
and to hold Seller and its affiliates and its and their officers, directors,
agents, and employees harmless from and against any and all liability, loss,
cost, and expense, however arising, as a result of release of information and/or
files concerning the referenced employees.

         7.2  TERMS AND CONDITIONS OF EMPLOYMENT. Except as otherwise provided
explicitly in this Agreement, the terms of employment for each Transferred
Employee shall be determined solely by Purchaser's policies, procedures, and
programs; provided, however, that Purchaser agrees that each Transferred
Employee shall be provided employment subject to the following terms and
conditions:

              (a)  Base salary shall be at least equivalent to the rate of base
salary paid by Seller to such Transferred Employee as of the close of business
on the day prior to the Closing Date.

              (b)  Except as otherwise specifically provided herein, Transferred
Employees shall be provided employee benefits that are no less favorable in the
aggregate than those provided to similarly situated employees of Purchaser.
Purchaser shall provide such Transferred Employees with credit for the
Transferred Employee's period of service with Seller (including any service
credited from predecessors by merger or acquisition to Seller) towards the
calculation of eligibility and vesting for such purposes as vacation, sick days,
personal days, severance and other benefits, and

                                       16
<PAGE>   17

participation and vesting in Purchaser's qualified pension and/or profit sharing
401 (k) plans, as such plans may exist (but not for purposes of funding of
accrued pension or profit sharing plans for such Transferred Employees with
respect to any period prior to the Closing Date).

              (c)  Each Transferred Employee currently participating in Seller's
medical, dental, health, health or other welfare plan, shall be eligible to
participate in the medical, dental, or other welfare plans of Purchaser, as such
plans may exist, on and after the Closing Date, and any pre-existing conditions
provisions of such plans shall be waived with respect to any such Transferred
Employees.

              (d)  With respect to any Transferred Employee who is also a Leave
Employee, upon conclusion of his or her short-term disability or temporary leave
of absence, subject to the terms and conditions of the Purchaser's plans and
policies and applicable law, each Transferred Employee on such leave shall
receive the salary and vacation benefits in effect when he or she went on leave,
shall otherwise be treated as a Transferred Employee, and, to the extent
practicable, shall be offered by the Purchaser the same or a substantially
equivalent position to his or her position with Seller prior to having gone on
leave.

              (e)  Except as provided herein, Seller shall pay, discharge, and
be responsible for (i) all salary and wages arising out of employment of the
Transferred Employees through the Closing Date, and (ii) any employee benefits
arising under Seller's employee benefit plans and employee programs prior to the
Closing Date (but not including sick days and personal days accrued but unused
by the Transferred Employee through the Closing Date and medical benefits, if
any, to Transferred Employees who retire after the Closing Date), including
benefits with respect to claims incurred prior to the Closing Date but reported
after the Closing Date and benefits inuring to Leave Employees prior to any
election by such Leave Employees to return to work with Purchaser. From and
after the Closing Date, Purchaser shall pay, discharge, and be responsible for
all salary, wages, and benefits arising out of or relating to the employment of
the Transferred Employees by Purchaser from and after the Closing Date,
including, without limitation, all claims for welfare benefits plans incurred on
or after the Closing Date. Claims are incurred as of the date services are
provided notwithstanding when the injury or illness may have occurred. To the
extent permitted under Purchaser's applicable 401 (k) plan, Seller and Purchaser
shall cooperate in arranging for the transfer to Purchaser's 401 (k) plan, as
soon as practicable after the Closing Date and in a manner that satisfies
sections 414(1) and 411 (d)(6) of the Internal Revenue Code, as amended, of
those accounts held under Seller's 401 (k) plan on behalf of Transferred
Employees.

         7.3  COMPLIANCE WITH LAW. Purchaser agrees that it shall comply with
any and all applicable requirements, if any, under the Worker Adjustment and
Retraining Notification Act in connection with the transaction contemplated by
this Agreement. Purchaser hereby agrees to indemnify and to hold Seller and its
affiliates and its and their officers, directors, agents, and employees harmless
from and against any and all liability, loss, cost, and expense, however
arising, as a result of the failure of Purchaser to comply with its obligations
as set forth in this section.

         7.4  ACTIONS TO BE TAKEN BY SELLER. Seller covenants to Purchaser that
it will do or cause

                                       17
<PAGE>   18

the following to occur:

              (a)  COVENANT NOT TO COMPETE. Seller [and John G. Yedinak,
individually] shall not, directly or indirectly, by or through any of its
directors, officers, employees, agents or subsidiaries, solicit deposits, market
any of its financial services (except for the existing mortgage and mortgage
purchase and resale business it currently operates under the name of "Margo
Financial Services", hereinafter "Margo") or engage in any retail banking or
provide financial services that are in direct competition with the business of
Purchaser, for a period of five (5) years within the Market Area of the Branch
whose business is being transferred under this Agreement [Market Area being
defined for the purposes of this Agreement to be within a radius of ten (10)
miles from 8627 S. Roberts Road, Bridgeview, Illinois]; EXCEPT that any area
within said ten mile radius which falls west of I-294 and north of I-55 and
South of I-88, shall be deemed to be outside of the Market Area for the
purposes of this Covenant not to Compete. Notwithstanding the foregoing it is
understood and agreed that Seller shall change its name to "Umbrellabank" or
"Umbrellabank.com" or such other name which is not similar to "Argo" as soon
after the Closing of this transaction as the required regulatory approvals for
such a name change can be secured [Seller shall apply for said approval(s)
within thirty (30) days after the closing and provide Purchaser with evidence of
said application] and to continue to provide banking and related services
outside of the Market Area and conduct an electronic banking business under the
name of "Umbrellabank.com" both within and outside of the Market Area and that
said electronic banking business shall be exempt from the provisions of this
Covenant not to Compete PROVIDED that the marketing of said Umbrellabank.com's
services shall not be specifically targeted to the Market Area or the customers
of Seller whose accounts are being transferred to Purchaser under this Agreement
and that the name of "Argo Federal Savings Bank" is not used in connection with
any marketing of Umbrellabank.com's or Seller's services in the Market Area
during the term of this Covenant not to Compete (except to the extent that
banking regulations require the screen on Seller's Automated Teller Machines
("ATM's) to identify Umbrellabank as a "division of Argo Federal Savings Bank"
or to otherwise comply with banking regulations). Seller shall not install any
Automated Teller Machines (ATM's) within the Market Area (as defined
hereinabove) during the term of this Covenant, except that in the event that
Seller is obligated under any existing (or future) contracts to install ATMs
within the Market Area during the term of the Covenant not to Compete, Purchaser
shall have a right of first refusal to license each such additional ATM
installed, such right of first refusal to be expressly exercised by Purchaser in
a writing delivered to Seller within ten (10) days of receipt of written notice
thereof by Seller. If Purchaser exercises said right of first refusal, Purchaser
shall reimburse Seller for Seller's costs of installing said ATM, including the
cost of the ATM, labor and installation charges, and signage [the design and
content of said signage to be reasonably acceptable to Purchaser], and shall pay
a monthly fee to the Seller based on transaction volume at the rate of twenty
($0.20) cents per transaction. If Purchaser declines to exercise said right of
first refusal as provided herein, Seller shall have the right to install such
ATM(s) subject to the restrictions contained herein concerning the use of the
name "Argo" on said ATM(s).

         Notwithstanding the provisions contained herein to the contrary, it is
understood that Seller shall continue to operate its existing branches located
at 14076 Lincoln Avenue, Dolton, Illinois, 2154 West Madison Street, Chicago,
Illinois, 47 West Polk Street, Chicago, Illinois (to the extent that said

                                       18
<PAGE>   19

branch is not sold to an affiliate of Purchaser) and at site to be located
within a one (1) mile radius of the intersection of Chicago Avenue and Halsted
Street in Chicago, Illinois or any other location outside the Market Area, under
its existing name until the name change referred to hereinabove shall be
approved (and thereafter under its name as so changed) and that the continued
operation of said branches by Seller shall not constitute a breach of the
Covenant not to Compete provided that the services of said branches shall not be
specifically targeted to the Market Area or the customers of Seller whose
accounts are being transferred to Purchaser under this Agreement. In addition,
it is agreed that Seller may maintain its corporate offices and the office of
"Margo" at their present location at 5818 Archer Road, Summit, Illinois subject
to the restrictions contained in this Covenant not to Compete.

         It is further agreed that in the event that Seller, or any entity in
which John G. Yedinak (hereinafter "Yedinak") is an officer, director or
employee, shall seek to acquire any financial institution which is located
outside of the Market Area during the term of this Covenant not to Compete, but
which institution has a branch located within the Market Area, Purchaser shall
have a right of first refusal with respect to any such branch(es) as may be
located within the Market Area, to be exercised by Purchaser in writing within
thirty (30) days after receiving written notice from Seller and/or Yedinak,
which notice shall contain all of the terms and conditions of said proposed
acquisition and the usual and customary information and opportunity required by
a Purchaser to conduct due diligence.

              (b)  ENFORCEABILITY. The parties believe that the restrictive
covenants contained in this paragraph are reasonable. However, if any court of
competent jurisdiction subsequently holds these restrictions to be unreasonable,
whether as to scope, territory, or period of time specified herein, such scope,
territory, or period of time shall be deemed to be that which the court shall
declare or deem to be reasonable.

              (c)  INJUNCTIVE RELIEF. Seller recognizes that Purchaser may
suffer irreparable damage if the terms of this restrictive covenant are
violated, and that it will be difficult, if not impossible, to compute
Purchaser's actual damages resulting from such unauthorized competition. The
parties therefore agree that Purchaser may apply to a court of competent
jurisdiction to enjoin any threatened or actual breach of the covenants
contained herein, and that the prevailing party in any ensuing action shall be
entitled to recover its reasonable expenses, including court costs and
reasonable attorney's fees.

              (d)  SOLICITATION OF TRANSFERRED EMPLOYEES. Except with the
written consent of Purchaser, for a period of eighteen (18) months following the
Closing Date, Seller will not, directly or indirectly, solicit Transferred
Employees as prospective officers or employees of Seller; provided, however,
that Seller shall not be prohibited or restricted from hiring a Transferred
Employee if such Transferred Employee is terminated by Purchaser.
Notwithstanding anything herein to the contrary, it is agreed that any
transferred Employee who is hired by Seller after the Closing Date, shall be
bound by the terms of the Covenant not to Compete herein above set forth by
virtue of their employment by Seller.

                                       19
<PAGE>   20

              (e)  EMPLOYEE BENEFIT PROGRAMS. Seller's obligations to employees
of the Branch Office, including Transferred Employees, will be as set forth in
established policies of Seller, and Seller shall continue its employee benefit
programs in full force and effect as benefit programs for Transferred Employees
through the Closing Date. After the Closing, Seller shall retain the
responsibility and liability for the funding and payment of all claims incurred
under such employee benefit programs through the Closing Date. Purchaser shall
have no obligation or liability to compensate Transferred Employees for benefits
of any kind earned, accrued, promised and/or provided to Transferred Employees
as employees of Seller, except with respect to eligibility and vesting as set
forth in Paragraph 7.2 above.

              (f)  EMPLOYEES OF THE BRANCH OFFICE. Seller shall not, without
Purchaser's prior written consent (i) increase the aggregate full-time
equivalent size of the work force at the Branch Office above the aggregate
normal staffing levels designated by Seller for the Branch Office at the date
hereof, (ii) terminate any Transferred Employee prior to the Closing Date,
unless such person is terminated for cause as determined at the sole discretion
of Seller or otherwise pursuant to existing Seller policies or procedures, or
(iii) increase the compensation of any Transferred Employee except pursuant to
existing Seller policies and procedures.

              The obligations of Seller and Purchaser pursuant to this ARTICLE
VII shall survive the Closing.

                                  ARTICLE VIII
                              ADDITIONAL AGREEMENTS

         8.1  COOPERATION. Purchaser and Seller further covenant and agree that
each shall cooperate in expeditiously obtaining all necessary or appropriate
governmental approvals, consents or permits and in preparing any and all
applications contemplated by this Agreement, and will furnish such supporting
information or exhibits as may be required, and will not do, sanction or
knowingly permit any person under the control of each to do anything which might
in any way hinder, delay or prevent the expeditious approval of the transactions
contemplated by this Agreement or the orderly transition of Seller's customers
to Purchaser, or commit any act or omission which might be reasonably expected
to have such an effect.

         8.2  CONFIDENTIALITY. Purchaser and Seller each agree to keep
confidential all information, documents, books, records and any other material
no matter how obtained from the other party hereto unless and until the
transaction contemplated herein is consummated, and if such transaction is not
consummated, each party hereto will return or cause to be returned to the
applicable party all such documents, material and information then in its
possession, or the possession of a representative of either, and neither party
hereto will divulge or use such information until it becomes known generally to
the public.

<PAGE>   21

         9.1  TRANSITIONAL ACTION BY PURCHASER. After the Closing, unless
another time is otherwise indicated:

              (a)  Purchaser shall: (i) pay in accordance with the law and
customary banking practices and applicable Account contract terms, all properly
drawn and presented checks, negotiable orders of withdrawal, drafts, debits, and
withdrawal orders presented to Purchaser by mail, over the counter, through
electronic media, or through the check clearing system of the banking industry,
by depositors of the Transferred Accounts assumed by Purchaser hereunder,
whether drawn on checks, negotiable orders or withdrawal, drafts, or withdrawal
order forms provided by Purchaser or Seller; and (ii) in all other respects
discharge, in the usual course of the banking business, the duties and
obligations of Seller with respect to the balances due and owing to the
depositors whose Accounts are assumed by Purchaser hereunder; provided, however,
that any obligations of Purchaser pursuant to this Paragraph 9.1 to honor
checks, negotiable orders of withdrawal, drafts, and withdrawal orders on forms
provided by Seller and carrying its imprint (including its name and transit
routing number) shall not apply to any checks, drafts, withdrawal orders, or
returned items (i) presented to Purchaser more than two hundred ten (210) days
following the Closing Date, or (ii) on which a stop payment has been requested
by the deposit customer. Purchaser shall submit and file any required reports on
IRS Form 1099 with respect to interest accrued on Transferred Accounts after the
Closing Date. The provisions of this subsection 9.1 (a) shall in no way limit
Purchaser's duties or obligations arising under Paragraphs 1.3 and 1.4 hereof.

              (b)  Purchaser shall, not earlier than ten days after the time of
procurement of all regulatory approvals required for consummation of the
transaction contemplated by this Agreement nor later than five days prior to the
Closing Date, notify all depositors of the Offices by letter, acceptable to
Seller, produced in, if appropriate, several similar, but different forms
calculated to provide necessary and specific information to the owners of
particular types of accounts, of Purchaser pending assumption of the Transferred
Accounts hereunder, and, in appropriate instances, notify depositors that on and
after the Closing Date certain Seller deposit-related services and/or Seller's
debit card and automatic teller machine services impacted by the transactions
contemplated by this Agreement, will be terminated. As an enclosure to such
notices, Purchaser may furnish appropriate depositors with brochures, forms and
other written materials related or necessary to the assumption of the Accounts
by Purchaser and the conversion of said accounts to Purchaser accounts,
including the provision of checks to appropriate depositors using the forms of
Purchaser with instructions to such depositors to utilize such Purchaser checks
on and after the Closing Date and thereafter to destroy any unused checks on
Seller's forms. The expenses of the printing, processing and mailing of such
letter notices and providing new Purchaser checks and other forms and written
materials to appropriate customers shall be borne by Purchaser. Before Closing,
except as provided in this paragraph, Purchaser will not contact Seller's
customers except as may occur in connection with advertising or solicitations
directed to the public generally or in the course of obtaining the requisite
regulatory approvals of the transaction. Anything to the contrary herein
notwithstanding, Purchaser shall provide, at no cost to Seller, any and all
notices, communications, and filings which may be required by law, regulation,
or otherwise, relating to any changes in terms and other matters relating to the
Accounts occurring subsequent to the Closing Date. Any and all such notices,
communications, and filings which may be required to be provided prior to the
Closing Date shall be

                                       21
<PAGE>   22

submitted on a timely basis for review by Seller and shall be subject to the
written approval of Seller prior to delivery to any third party. Purchaser shall
provide, at its sole cost and expense and at no cost or expense to Seller, that
any and all customer and other notices, communications, and filings provided by
Purchaser hereunder, including the substance and timing of same, fully comply
with the requirements of applicable law and regulation.

              (c)  Purchaser shall promptly pay to Seller an amount equivalent
to the amount of any checks, negotiable orders of withdrawal, drafts, withdrawal
orders, or returned items (net of the applicable Deposit Premium paid by
Purchaser with respect to the Transferred Accounts represented by any such
instrument) credited as of the close of business on the Closing Date to an
Account assumed by Purchaser hereunder which are returned uncollected to Seller
after the Closing Date. The foregoing shall include an amount equivalent to
holds placed upon such deposit account for items cashed by Seller as of the
close of business on the Closing Date.

              (d)  Purchaser shall, not later than the close of business on the
business day immediately following the Closing Date, supply suitable
government-backed securities as security for any deposits of governmental units
included among the Transferred Accounts for which Seller had provided similar
security.

              (e)  Purchaser hereby grants to Seller and its contractors access
to the Branch Office until 8:00 A.M. local time on the day following the
Transfer Date or such other later date and time as the parties may agree, at no
cost or expense to Seller, for conduct of activities consistent with this
Agreement in conjunction with the transactions contemplated hereby.

              (f)  The duties and obligations of Buyer in this Paragraph 9.1
shall survive the Closing.

         9.2  TRANSITIONAL ACTIONS BY SELLER. After the Closing, unless another
time is otherwise indicated:

              (a)  Seller shall use its best efforts to cooperate with Purchaser
in assuring an orderly transition of ownership of the Assets and responsibility
for the liabilities, including the Transferred Accounts, assumed by Purchaser
hereunder. Seller shall provide final statements as of the Closing Date, in
conjunction with appropriate Transferred Accounts, with interest and service
charges pro-rated to close of business on the Closing Date. Seller shall submit
and file any required reports on IRS Form 1099 with respect to interest paid on
Transferred Accounts through the Closing Date. Notwithstanding the limitations
contained in 9.1(b), Seller shall, prior to issuing any notices to its customers
or the general public regarding the transaction contemplated by this Agreement,
obtain the prior written consent of Purchaser with respect to the content of
such notices. Purchaser shall not contact Seller's customers until the earlier
of (i) Seller's written consent, or (ii) receipt of all regulatory approvals and
the passage of any waiting periods, and all conditions precedent to Purchaser's
obligations hereunder have either been satisfied or waived in writing by
Purchaser.

              (b)  Prior to the Closing Date, Seller shall cooperate with
Purchaser, at Purchaser's

                                       22
<PAGE>   23

expense and at no expense to Seller, in making Transferred Employees available
at reasonable times for whatever program of training Purchaser deems advisable;
provided, however, that Purchaser shall conduct such training program in a
manner that does not materially interfere with or prevent the performance of the
normal duties and activities of such Transferred Employees. Purchaser shall make
request of Seller for training opportunities prior to the Closing Date, and
shall reimburse Seller at the Closing for any and all costs relating to such
training including, but not limited to, regular and overtime salary for
Transferred Employees involved in training for the period of such training,
travel costs, and all expenses incurred by Seller or such Transferred Employees
in conjunction with the training. Such requests, which shall specify the time,
duration and place of such training, must be approved by Seller.

              (c)  Seller shall cooperate with Purchaser, at no expense to
Seller, to make provision for the installation of teller and platform equipment
in the Branch Office subject to approval by Seller; provided, however, that
Purchaser shall arrange for the installation and placement of such equipment at
such times and in a manner that does not significantly interfere with the normal
business activities and operation of Seller or the Branch Office.

              (d)  Seller shall resign as custodian of each IRA account
maintained at the Branch Office and assign the custodianship of such accounts to
Purchaser upon Closing subject to receipt of applicable customer consents and
other and analyze such provisions of this Agreement.

              (e)  Seller shall terminate its ATM/debit card service effective
as of close of business on the business day preceding the Closing Date or such
other date and time as Seller and Purchaser may agree. Such terminations will be
preceded by the notice described in Paragraph 9.1(b) herein. Seller shall have
no obligation with respect to conversion or change over with respect to direct
deposit or payroll and retirement payments service relating to the Transferred
Accounts following the Closing and, further, Purchaser shall assume all
responsibility and liability with respect thereto following the Closing. Seller
will continue to redirect and/or pass through relevant ACH transactions on
Transferred Accounts for a period of two hundred ten (210) days following the
Closing Date.

              (f)  As of the opening of business on the first business day after
the Closing Date, Seller and Purchaser shall provide the appropriate Federal
Reserve Bank (the "FRB") with all information necessary in order to expedite the
clearing and sorting of all checks, drafts, instruments and other commercial
paper relative to the Transferred Accounts (hereinafter collectively referred to
as "Paper Items"). Purchaser shall bear all charges and costs imposed by the
Federal Reserve in connection with the reassignment of account number ranges for
sorting the Paper Items.

              In the event the Federal Reserve and/or any other regional or
local clearinghouse for negotiable instruments fails, refuses or is unable to
direct sort such Paper Items for delivery to Purchaser with the result that such
Paper Items are presented to Seller, by not later than 3:00 p.m. local time on
each business day following the Closing and continuing for two hundred ten (210)
days after the Closing, Seller will make available to Purchaser for pick up from
Seller's offices or the offices of Seller's agent and/or processor at 7600 West
63rd Street, Summit, Illinois all of the Paper

                                       23

<PAGE>   24

Items which are received by Seller from the FRB and/or any regional or local
clearinghouse during the morning of each such business day on an "as-received
basis." At the same time Seller shall also make available to Purchaser
information and records, including but not limited to systems printouts,
concerning such Paper Items and concerning incoming Automated Clearing House
items ("ACH items") as well as outstanding Automatic Teller Machine ("ATM")
transactions. Such information and records, including but not limited to systems
printouts, will utilize the most recent account number designated by Seller for
each of the Transferred Accounts. Purchaser shall initiate appropriate
Notification of Change requests relating to appropriate routing matters at the
sole expense of Purchaser within 30 days following the Closing Date. Each
business day Seller will endeavor to see that the sum of (a) the actual Paper
Items provided to Purchaser plus (b) all ACH items and ATM transactions captured
by Seller in its information and records balance with the sum of (c) the
information and records, including but not limited to systems printouts,
provided by Seller relative to the Paper Items plus (d) the information and
records, including but not limited to systems printouts, provided relative to
the ACH items and ATM transactions affecting the Transferred Accounts.

              Except as otherwise expressly provided herein, Seller shall
provide the foregoing at no charge to Purchaser for a period not to exceed
thirty (30) days from the Closing Date except that Purchaser shall pay any
charges assessed to Seller by the FRB, a national or local clearinghouse and/or
Seller's agent and/or processor to the extent such assessments relate to the
Transferred Accounts ("Costs"). Purchaser shall be responsible for pick up of
the data to be provided by Seller and shall compensate Seller for activity
subsequent to the referenced 30 day period as follows: (i) $50.00 per day and
Seller's Costs plus ten (10%) percent thereof for days 31 through 60; (ii)
$50.00 per day and Seller's Costs plus fifteen (15%) percent thereof for days 61
through 120; and (iii) $50.00 per day and Seller's Costs plus twenty-five (25%)
percent thereof for days 121 through 180. Any request for extension of the
180-day period shall be submitted in writing by Purchaser to Seller not later
than 10 business days prior to the expiration of such 180-day period or any
extensions thereof and shall be subject to approval by Seller at its sole
discretion. Fees for activity subsequent to the 180 day period shall be as
determined by Seller. Fees for activity subsequent to the initial 30-day period
shall be assessed on a daily basis and included in the daily cash settlement.

              Except as otherwise expressly provided herein, Purchaser shall be
responsible for processing any and all ACH returns, received subsequent to the
Closing, directly through the appropriate Federal Reserve Bank.

              Seller and Purchaser shall arrange for appropriate daily
settlement between the parties in order that the transmission of all monies
associated with the matters set forth in this Paragraph 9.2(f) might be effected
promptly.

              Seller shall not be liable to Purchaser for any failure to provide
the data required by this Paragraph 9.2(f) to the extent any such failure
results from causes beyond Seller's control including war, strike or other labor
disputes, acts of God, errors or failures of the FRB, and/or a participating
regional or local clearinghouse, or equipment failure or other emergency wherein
Seller and/or its agent processor has been unable to process in clearings from
the FRB or such

                                       24

<PAGE>   25

clearinghouse.

              (g)  Seller shall, not earlier than the time of procurement of all
regulatory approvals required for consummation of the transaction contemplated
by this Agreement nor later than twenty days prior to the Closing Date, notify
all depositors of the Branch Office by letter acceptable to Purchaser, produced
in, if appropriate, several similar, but different forms calculated to provide
necessary and specific information to the owners of particular types of accounts
and/or loans, of Purchaser's pending assumption of the Transferred Accounts,
and, in appropriate instances, notify depositors that on and after the Closing
Date certain Seller deposit-related services and/or Seller's debit card and
automatic teller machine services, will be terminated. The expenses of the
printing, processing and mailing of such letter notices shall be borne by
Seller. Anything to the contrary herein notwithstanding, nothing in this
Agreement shall be deemed to constitute an assumption by Seller of the duties
and obligations of Purchaser with respect to the provision of applicable
notices, communications, and filings relating to changes in the terms of any
Transferred Accounts as set forth in this Agreement.

              (h)  The duties and obligations of the parties in this Paragraph
9.2 shall survive the Closing.

         9.3  OVERDRAFTS AND TRANSITIONAL ACTION. Overdrafts on the Transferred
Accounts up to and including the date of Closing will be the responsibility and
risk of Seller and all fees associated therewith shall be the property of
Seller. Overdrafts on the Transferred Accounts after the date of Closing will be
the responsibility and risk of Purchaser and all fees associated therewith shall
be the property of Purchaser.

         9.4  ATM'S AND DEBIT CARDS.

         (a)  In accordance with the provisions of Section 4.7 hereinabove,
Seller shall provide to Purchaser and/or Purchaser's data processor, a test tape
no later than sixty (60) days prior to the closing date and a production tape no
later than thirty (30) days prior to the closing date so that Purchaser may
produce AB or CCB ATM/Debit cards with the same PIN number as the customer is
currently utilizing for their ATM/Debit card transactions prior to Closing. Both
tapes shall include file formats and/or file layouts of all ATM/Debit card
information and all related custumer information. Seller shall further provide
any and all information and assistance required by Purchaser as are reasonable
and customary in conversions of the kind contemplated by this Agreement. In
addition, from the date that the production tape is produced until the Data
Processing Conversion, Seller shall maintain, make available and deliver to
Purchaser a manual log of all new/replacement cards issued, changes to existing
cards/PIN numbers, and other such data so that Purchaser may make similar manual
changes to cards being produced for customers to be used after the date of the
Data Processing Conversion. Upon the Data Processing Conversion, Seller's Data
Processor shall deactivate the operation of the Seller's ATM/Debit cards with
respect to the Transferred Accounts. Purchaser and Seller agree to settle, on a
daily basis, the net amount of ATM debits/credits associated with transferred
accounts until the conversion date. Seller shall provide all necessary
information and reports with respect to such ATM/Debit card activity on the
Transferred Accounts

                                       25
<PAGE>   26

so that Purchaser may appropriately debit/credit the Transferred Accounts for
such ATM/Debit card activity and balance sais activity to the General Ledger or
Settlement Accounts.

              (b         (c)  Purchaser and Seller agree to cooperate with each
other to assure that all transactions originated through the ATM or originated
with the ATM Cards prior to or on the Closing Date shall be for the account of
Seller and all transactions originated after the Closing Date shall be for the
account of Purchaser. A post closing adjustment shall be made to reflect all
such transactions, which cannot be reasonably calculated as of the Closing.

              (c)  In addition to the other payments to be made by Purchaser
hereunder, Purchaser agrees to also purchase the ATM terminal located at 5818
Archer Road, Summit, Illinois, for the book value of said ATM as of the Closing
Date and to enter into a lease for such ATM site in accordance with the
provisions of Schedule 9.4(d).

Directors of Seller if any of the conditions provided in ARTICLE V shall not
have been satisfied, complied with or performed in any material respect, and

condition contained in the approval of the transactions contemplated by this
Agreement by the FDIC, FRB, OBRE or the OTS will be subject to the consent of

of this Agreement.

         If termination of this Agreement shall be judicially determined to have
been caused by breach of this Agreement by either party, then, in addition to
other remedies at law or equity for breach of this Agreement, breaching party
shall indemnify the other party for its costs, fees and expenses of its counsel,
accountants and other experts and advisors as well as fees and expenses incident
to negotiation, preparation and execution of this Agreement in related actions.

coverage relating to claims arising from Seller's administration of the
Transferred Accounts prior to the Closing Date shall, to the extent assignable,
be assigned to Purchaser. To the extent such insurance claims are either a) not
transferable or b) not otherwise covered by any insurance, then Seller agrees to
indemnify, defend, and hold Purchaser harmless from any losses, judgments,
expenses, attorneys fees or costs threatened or incurred by Purchaser as a
result of such claims, provided, however, that Seller shall not indemnify,
defend or hold Purchaser harmless from Purchaser's own negligence or willful

and conditions set forth herein, Purchaser and Seller hereby covenant and agree
as follows:

and/or employees of Seller who do not work at the Branch Office.

         1.2  IDENTIFICATION OF TRANSFERRED ACCOUNTS BY EXHIBIT. Marked Schedule

format to previous reports tendered by Seller setting forth the identity of
holder, the type of account, account opening date, account maturity date,
principal balance (including accrued and credited interest of such account), and
interest rate payable on each of the Transferred Accounts as of July 31, 2000.
Seller shall also provide, or make available, to Purchaser such other account

of business on the day preceding the Closing Date (as defined in Article VI
hereof), Seller hereby agrees to deliver to Purchaser a supplemental statement
verifying the information set forth in the preceding sentence together with such
information with respect to any new or additional accounts opened after August
1, 2000 on each of the Accounts to be transferred to Purchaser as of the date
three (3) days prior to the Closing Date (such 3-day period the "Gap Period") as
well as an identification of any accounts which were closed between the date of
the original Schedule 1.2 and Supplemental Schedule 1.2. A Post-closing Schedule
1.2 covering the Gap Period shall be delivered by Seller to Purchaser within ten

Transferred Accounts by Seller, but not due for payment as of the Closing Date,
shall be transferred to Purchaser in current funds pursuant to Paragraph 1.4
hereof, and Purchaser shall thereupon assume the liability therefor.

         1.3  TRANSFER. Purchaser shall assume the liability for and thereafter
discharge, pay in full and perform all of Seller's obligations and duties

value of the Account, Purchaser having assumed the liability for the Transferred
Accounts subject to the indemnification provisions contained herein and the
existing rights, delegations, assignments, appointments, powers of appointment
and privileges of the Account holders. Thereafter, each such account holder
shall be entitled to all of the rights and privileges of an account holder of
Purchaser, as prescribed by its Articles of Incorporation, Bylaws and account
rules and, when appropriate, be issued proper account documentation evidencing
such account in Purchaser. Purchaser shall continue to recognize the terms and
maturities of all of the transferred accounts as of the Closing Date until the
originally stated maturity date. Thereafter, such accounts shall be renewed upon
the terms of Purchaser for similar accounts. Purchaser shall be responsible for
all regulatory filings and for the issuance of Forms 1098 and 1099 for all
periods ending after the Closing Date. Seller shall be responsible for all
regulatory filings and for the issuance of forms 1098 and 1099 for all periods

         4.7  CONSENT OF OTHER PERSONS.

              (i)  Purchaser and Seller shall have received the consent of
On-Line Financial Services, Inc. ("OLFSI"), Seller's data processor, to the
conversion by Purchaser of the Transferred Accounts to Flserv CIR, Inc.
(hereinafter referred to as "Purchaser DP") (the "Data Processing Conversion").
The Data Processing Conversion shall be completed within one hundred and eighty
(180) days after the Closing Date. OLFSI shall covenant and consent to provide
Purchaser and/or Purchaser DP all system documentation, file layouts and files
on tape in a form acceptable to Purchaser DP within sixty (60) days prior to the

Purchaser and/or Purchaser DP as are reasonable and customary in conversions of
the kind contemplated by this Agreement. All costs and fees customarily assessed
by OLFSI to Seller for such data processing services in connection with the Data
Processing Conversion shall be paid by Seller. Purchaser shall pay all costs and
fees assessed by Purchaser's DP for the Data Processing Conversion. In the event
that reports or services are required by Purchaser and/or Purchaser's DP from
OLFSI in order to complete the conversion, which are not customarily assessed by
OLFSI to Seller, the cost of said reports or services shall be paid by Purchaser
or its affiliates, up to a maximum of $35,000 for the three branches being
purchased by Purchaser or its affiliates from Seller, and any amount in excess
of $35,000 shall be paid one-half by Purchaser and one-half by Seller.

              (ii) To the extent that any other material lease, contract or
Agreement to which Seller is a party and which is related to the terms of this
Agreement shall require the consent of any other person to the transactions
contemplated herein, such consent shall have been obtained by the Closing Date;
provided, however, that Seller shall not make as a condition for the obtaining
of any such consent, any agreements or undertakings not approved by Purchaser.

         4.8  LITIGATION. No suit, action or proceeding by any governmental
agency shall have been instituted or threatened seeking to (i) enjoin, restrain
or prohibit the consummation of the transactions contemplated by this Agreement
which would in the reasonable judgment of Purchaser make it inadvisable to
consummate such transactions, or to (ii) cause any of the transactions
contemplated by this Agreement to be rescinded following consummation, or (iii)
that would affect adversely the right of Purchaser to operate the Branch Office
as a Branch Office of Purchaser; and no court order shall have been entered in
any action or proceeding instituted by any other person which enjoins, restrains
or prohibits this Agreement or consummation of the transactions contemplated by
this Agreement. No statute, rule, regulation, order, injunction or decree shall
have been enacted, entered, promulgated or enforced by a governmental entity,
which prohibits, restricts or makes illegal consummation of the transactions
contemplated hereby.

Seller and all instruments executed and delivered by Seller on or prior to the
close of business on the Closing Date, in connection with the transactions

         4.10 NO ADVERSE CHANGES. Between the date of this Agreement and the
Closing Date, the business of the Branch Office shall be conducted in the
ordinary course, consistent in all material respects with prudent banking
practices; there shall not have occurred any material adverse change or any
condition, event, circumstance, fact or occurrence that may be expected to

date of this Agreement, Purchaser shall commence a not greater than ten (10)
business day due diligence examination of the Branch Office, including the
Assets, Accounts, and all other contracts, agreements and/or documents related
to the transactions contemplated by this Agreement (the "Initial Investigation")
and if Purchaser decides not to proceed with the transaction contemplated by
this Agreement as a result of such investigation, Purchaser shall so advise
Seller in writing within such ten (10) day period. Purchaser's failure to notify
Seller as aforesaid shall constitute satisfaction with the condition of the
Transferred Assets. Seller shall provide Purchaser full cooperation, disclosure
and complete access to all aspects of the Branch Office, including, but not
limited to all books, records, contracts, commitments, correspondence, accounts,

Investigation") consistent with the Initial Investigation. The due diligence
examinations contemplated hereby shall be conducted at the sole discretion of
Purchaser and Purchaser's right to terminate this Agreement as a result of the
Subsequent Investigation shall be based strictly upon the existence of a
material adverse change affecting the Transferred Assets which Seller cannot or
will not cure within a reasonable period of time. No investigation by Purchaser
shall affect the representations and warranties of Seller set forth herein.

         4.12 OLFSI AGREEMENT. OLFSI and Purchaser shall have agreed to the fees
and expenses to be charged by OLFSI to Purchaser for data processing services to
be provided by OLFSI to Purchaser (other than conversion fees) following the
Closing and until completion of the Data Processing Conversion set forth in
Paragraph 4.7(i), provided that Purchaser shall agree to OLFSI's fees and
expenses so long as the same are reasonable and are acceptable to Purchaser.
OLFSI shall agree to provide Purchaser and Purchaser DP separate financial
information and data relative to the Branch Office, including but not limited to
(to the extent available) separate general ledger and trial balance reports
together with all other daily reporting to the Branch Office as reasonably
requested by Purchaser and/or Purchaser DP until the completion of the Data
Processing Conversion as more fully described in Paragraph 4.7(i). Seller and

                    ACTIONS RESPECTING EMPLOYEES AND PENSIONS
                           AND EMPLOYEE BENEFIT PLANS.

         7.1  EMPLOYMENT OF EMPLOYEES.

              (a) Purchaser shall extend offers of employment, as of the Closing
Date, to such employees of the Branch Office listed in Schedule 7.1(a) attached
hereto and incorporated herein, which schedule shall include the names of each
employee, their date of employment, salary, type of health plan coverage,
including single or family coverage, number of dependents and portion of premium

at the Branch Office as of the Closing Date (including, without limitation,
those employees who on the Closing Date are on family and medical leave,

not later than one (1) year following the Closing Date; individually and
collectively the "Leave Employees" herein) for positions entailing
responsibilities in effect at Seller as of the Closing Date, and for a base
salary not less than that paid by Seller as of the Closing Date. Employees
accepting employment with Purchaser, including but not limited to the Leave
Employees, are referred to herein individually and collectively as the
"Transferred Employees." In the event that Purchaser shall transfer (except in a
comparable position and for comparable compensation to an office not more than
35 miles from the Branch Office at which the Transferred Employee is employed as
of the Closing Date, or at the request of the Transferred Employee), terminate
employment of, or reduce the base salary of, a Transferred Employee (the
"Terminated Employee") between the Closing Date and the date which is one (1)
year from the Closing Date, other than for

                                       15
<PAGE>   46

cause, Purchaser shall pay to the Terminated Employee a sum equal to the greater
of that which the Terminated Employee would have received on the date of such
transfer, termination, or reduction in salary under the severance plan of Seller
applicable to the Terminated Employee as of the date hereof and set forth in
Schedule 7.1 or the severance plan of Purchaser otherwise applicable to the
Terminated Employee as of the date of such transfer, termination, or reduction
in base salary. Such payment shall be due and owing the Terminated Employee on
the date of such transfer, termination, or reduction in salary. Nothing
contained in this Agreement shall restrict or prohibit Purchaser and any
Transferred Employee from entering into an agreement satisfactory to both
Purchaser and the Transferred Employee providing for resolution of matters set
forth in this section.

              (b) Seller will cooperate with Purchaser, to the extent reasonably
requested and legally permissible, to provide Purchaser with information about
the employees of the Branch Office including, without limitation, providing
Purchaser with the personnel files of those employees of the Branch Office who
provide Seller with their written consent thereto, and a means to meet with the
subject employees. Purchaser hereby agrees to indemnify and to hold Seller and
its affiliates and its and their officers, directors, agents, and employees
harmless from and against any and all liability, loss, cost, and expense,
however arising, as a result of release of information and/or files concerning
the referenced employees.

         7.2  TERMS AND CONDITIONS OF EMPLOYMENT. Except as otherwise provided
explicitly in this Agreement, the terms of employment for each Transferred
Employee shall be determined solely by Purchaser's policies, procedures, and
programs; provided, however, that Purchaser agrees that each Transferred
Employee shall be provided employment subject to the following terms and
conditions:

              (a) Base salary shall be at least equivalent to the rate of base
salary paid by Seller to such Transferred Employee as of the close of business
on the day prior to the Closing Date.

              (b) Except as otherwise specifically provided herein, Transferred
Employees shall be provided employee benefits that are no less favorable in the
aggregate than those provided to similarly situated employees of Purchaser.
Purchaser shall provide such Transferred Employees with credit for the
Transferred Employee's period of service with Seller (including any service
credited from predecessors by merger or acquisition to Seller) towards the
calculation of eligibility and vesting for such purposes as vacation, sick days,
personal days, severance and other benefits, and participation and vesting in
Purchaser's qualified pension and/or profit sharing 401 (k) plans, as such plans
may exist (but not for purposes of funding of accrued pension or profit sharing
plans for such Transferred Employees with respect to any period prior to the
Closing Date).

              (c) Each Transferred Employee currently participating in Seller's
medical, dental, health, health or other welfare plan, shall be eligible to
participate in the medical, dental, or other welfare plans of Purchaser, as such
plans may exist, on and after the Closing Date, and any pre-existing conditions
provisions of such plans shall be waived with respect to any such Transferred
Employees.

                                       16
<PAGE>   47

              (d) With respect to any Transferred Employee who is also a Leave
Employee, upon conclusion of his or her short-term disability or temporary leave
of absence, subject to the terms and conditions of the Purchaser's plans and
policies and applicable law, each Transferred Employee on such leave shall
receive the salary and vacation benefits in effect when he or she went on leave,
shall otherwise be treated as a Transferred Employee, and, to the extent
practicable, shall be offered by the Purchaser the same or a substantially
equivalent position to his or her position with Seller prior to having gone on
leave.

              (e) Except as provided herein, Seller shall pay, discharge, and be
responsible for (i) all salary and wages arising out of employment of the
Transferred Employees through the Closing Date, and (ii) any employee benefits
arising under Seller's employee benefit plans and employee programs prior to the
Closing Date (but not including sick days and personal days accrued but unused
by the Transferred Employee through the Closing Date and medical benefits, if
any, to Transferred Employees who retire after the Closing Date), including
benefits with respect to claims incurred prior to the Closing Date but reported
after the Closing Date and benefits inuring to Leave Employees prior to any
election by such Leave Employees to return to work with Purchaser. From and
after the Closing Date, Purchaser shall pay, discharge, and be responsible for
all salary, wages, and benefits arising out of or relating to the employment of
the Transferred Employees by Purchaser from and after the Closing Date,
including, without limitation, all claims for welfare benefits plans incurred on
or after the Closing Date. Claims are incurred as of the date services are
provided notwithstanding when the injury or illness may have occurred. To the
extent permitted under Purchaser's applicable 401 (k) plan, Seller and Purchaser
shall cooperate in arranging for the transfer to Purchaser's 401 (k) plan, as
soon as practicable after the Closing Date and in a manner that satisfies
sections 414(1) and 411 (d)(6) of the Internal Revenue Code, as amended, of
those accounts held under Seller's 401 (k) plan on behalf of Transferred
Employees.

         7.3  COMPLIANCE WITH LAW. Purchaser agrees that it shall comply with
any and all applicable requirements, if any, under the Worker Adjustment and
Retraining Notification Act in connection with the transaction contemplated by
this Agreement. Purchaser hereby agrees to indemnify and to hold Seller and its
affiliates and its and their officers, directors, agents, and employees harmless
from and against any and all liability, loss, cost, and expense, however
arising, as a result of the failure of Purchaser to comply with its obligations
as set forth in this section.

         7.4  ACTIONS TO BE TAKEN BY SELLER. Seller covenants to Purchaser that
it will do or cause the following to occur:

         (a)  COVENANT NOT TO COMPETE. Seller [and John G. Yedinak,
individually] shall not, directly or indirectly, by or through any of its
directors, officers, employees, agents or subsidiaries, solicit deposits, market
any of its financial services (except for the existing mortgage and mortgage
purchase and repurchase business it currently operates under the name of "Margo
Financial Services", hereinafter "Margo") or engage in any retail banking or
provide financial services that are in direct competition with the business of
Purchaser, for a period of five (5) years within the Market Area of the Branch
whose business is being transferred under this Agreement [Market Area being
defined for the purposes of this Agreement to be within a radius of ten (10)
miles from 47 West Polk

                                       17
<PAGE>   48

Street, Chicago, Illinois]; Notwithstanding the foregoing it is understood and
agreed that Seller shall change its name to "Umbrellabank" or "Umbrellabank.com"
or such other name which is not similar to "Argo" as soon after the Closing of
this transaction as the required regulatory approvals for such a name change can
be secured [Seller shall apply for said approval(s) within thirty (30) days
after the closing and provide Purchaser with evidence of said application] and
to continue to provide banking and related services outside of the Market Area
and conduct an electronic banking business under the name of "Umbrellabank.com"
both within and outside of the Market Area and that said electronic banking
business shall be exempt from the provisions of this Covenant not to Compete
PROVIDED that the marketing of Seller's other branch locations and
Umbrellabank.com's services shall not be specifically targeted to the Market
Area or the customers of Seller whose accounts are being transferred to
Purchaser under this Agreement and that the name of "Argo Federal Savings Bank"
is not used in connection with any marketing of Umbrellabank.com's or Seller's
services in the Market Area during the term of this Covenant not to Compete
(except to the extent that banking regulations require the screen on Seller's
Automated Teller machines ("ATMs") to identify Umbrellabank as a "division of
Argo Federal Savings Bank" or to otherwise comply with banking regulations).

         Notwithstanding the provisions contained herein to the contrary, it is
understood that Seller shall continue to operate its existing branches located
at 14076 Lincoln Avenue, Dolton, Illinois, 2154 West Madison Street, Chicago,
Illinois [as well as 7600 West 63rd Street, Summit, Illinois and 8627 S. Roberts
Road, Bridgeview, Illinois to the extent that said branches are not sold to an
affiliate of Purchaser] and at a site to be located within a one (1) mile radius
of the intersection of Chicago Avenue and Halsted Street in Chicago, Illinois or
any other location outside the Market Area, under its existing name until the
name change referred to hereinabove shall be approved (and thereafter under its
name as so changed) and that the continued operation of said branches by Seller
shall not constitute a breach of the Covenant not to Compete provided that the
services of said branches shall not be specifically targeted to the customers of
Seller whose accounts are being transferred to Purchaser under this Agreement
and that the marketing of the branch at 2154 West Madison Street and the branch
at a location within a one mile radius of Chicago Avenue and Halsted Street,
will be limited to window signs and the monthly Near West Side gazette and
program books and ad books, said marketing not to be greater than the average of
such marketing at the branch at 2154 West Madison Street during the three month
period immediately prior to the date of this Agreement. In addition, it is
agreed that Seller may maintain its corporate offices and the office of "Margo"
at their present location at 5818 Archer Road, Summit, Illinois subject to the
restrictions contained in this Covenant not to Compete.

         It is further agreed that in the event that Seller, or any entity in
which John G. Yedinak (hereinafter "Yedinak") is an officer, director or
employee, shall seek to acquire any financial institution which is located
outside of the Market Area during the term of this Covenant not to Compete, but
which institution has a branch located within the Market Area, Purchaser shall
have a right of first refusal with respect to any such branch(es) as may be
located within the Market Area, to be exercised by Purchaser in writing within
thirty (30) days after receiving written notice from Seller and/or Yedinak,
which notice shall contain all of the terms and conditions of said proposed
acquisition and the usual and customary information and opportunity required by
a Purchaser to conduct due diligence.

                                       18

         (b) ENFORCEABILITY. The parties believe that the restrictive covenants
contained in this paragraph are reasonable. However, if any court of competent
jurisdiction subsequently holds these restrictions to be unreasonable, whether
as to scope, territory, or period of time specified herein, such scope,
territory, or period of time shall be deemed to be that which the court shall
declare or deem to be reasonable.

         (c) INJUNCTIVE RELIEF. Seller recognizes that Purchaser may suffer
irreparable damage if the terms of this restrictive covenant are violated, and
that it will be difficult, if not impossible, to compute Purchaser's actual
damages resulting from such unauthorized competition. The parties therefore
agree that Purchaser may apply to a court of competent jurisdiction to enjoin
any threatened or actual breach of the covenants contained herein, and that the
prevailing party in any ensuing action shall be entitled to recover its
reasonable expenses, including court costs and reasonable attorney's fees.

         (d) SOLICITATION OF TRANSFERRED EMPLOYEES. Except with the written
consent of Purchaser, for a period of eighteen (18) months following the Closing
Date, Seller will not, directly or indirectly, solicit Transferred Employees as
prospective officers or employees of Seller; provided, however, that Seller
shall not be prohibited or restricted from hiring a Transferred Employee if such
Transferred Employee is terminated by Purchaser. Notwithstanding anything herein
to the contrary, it is agreed that any transferred Employee who is hired by
Seller after the Closing Date, shall be bound by the terms of the Covenant not
to Compete herein above set forth by virtue of their employment by Seller.

         (e) EMPLOYEE BENEFIT PROGRAMS. Seller's obligations to employees of the
Branch Office, including Transferred Employees, will be as set forth in
established policies of Seller, and Seller shall continue its employee benefit
programs in full force and effect as benefit programs for Transferred Employees
through the Closing Date. After the Closing, Seller shall retain the
responsibility and liability for the funding and payment of all claims incurred
under such employee benefit programs through the Closing Date. Purchaser shall
have no obligation or liability to compensate Transferred Employees for benefits
of any kind earned, accrued, promised and/or provided to Transferred Employees
as employees of Seller, except with respect to eligibility and vesting as set
forth in Paragraph 7.2 above.

         (f) EMPLOYEES OF THE BRANCH OFFICE. Seller shall not, without
Purchaser's prior written consent (i) increase the aggregate full-time
equivalent size of the work force at the Branch Office above the aggregate
normal staffing levels designated by Seller for the Branch Office at the date
hereof, (ii) terminate any Transferred Employee prior to the Closing Date,
unless such person is terminated for cause as determined at the sole discretion
of Seller or otherwise pursuant to existing Seller policies or procedures, or
(iii) increase the compensation of any Transferred Employee except pursuant to
existing Seller policies and procedures.

         The obligations of Seller and Purchaser pursuant to this ARTICLE VII
shall survive the Closing.

                              ADDITIONAL AGREEMENTS

         8.1  COOPERATION. Purchaser and Seller further covenant and agree that
each shall cooperate in expeditiously obtaining all necessary or appropriate
governmental approvals, consents or permits and in preparing any and all
applications contemplated by this Agreement, and will furnish such supporting
information or exhibits as may be required, and will not do, sanction or
knowingly permit any person under the control of each to do anything which might
in any way hinder, delay or prevent the expeditious approval of the transactions
contemplated by this Agreement or the orderly transition of Seller's customers
to Purchaser, or commit any act or omission which might be reasonably expected
to have such an effect.

         8.2  CONFIDENTIALITY. Purchaser and Seller each agree to keep
confidential all information, documents, books, records and any other material
no matter how obtained from the other party hereto unless and until the
transaction contemplated herein is consummated, and if such transaction is not
consummated, each party hereto will return or cause to be returned to the
applicable party all such documents, material and information then in its
possession, or the possession of a representative of either, and neither party
hereto will divulge or use such information until it becomes known generally to
the public.

                                   ARTICLE IX
                              TRANSITIONAL MATTERS

         9.1  TRANSITIONAL ACTION BY PURCHASER. After the Closing, unless
another time is otherwise indicated:

              (a) Purchaser shall: (i) pay in accordance with the law and
customary banking practices and applicable Account contract terms, all properly
drawn and presented checks, negotiable orders of withdrawal, drafts, debits, and
withdrawal orders presented to Purchaser by mail, over the counter, through
electronic media, or through the check clearing system of the banking industry,
by depositors of the Transferred Accounts assumed by Purchaser hereunder,
whether drawn on checks, negotiable orders or withdrawal, drafts, or withdrawal
order forms provided by Purchaser or Seller; and (ii) in all other respects
discharge, in the usual course of the banking business, the duties and
obligations of Seller with respect to the balances due and owing to the
depositors whose Accounts are assumed by Purchaser hereunder; provided, however,
that any obligations of Purchaser pursuant to this Paragraph 9.1 to honor
checks, negotiable orders of withdrawal, drafts, and withdrawal orders on forms
provided by Seller and carrying its imprint (including its name and transit
routing number) shall not apply to any checks, drafts, withdrawal orders, or
returned items (i) presented to Purchaser more than two hundred ten (210) days
following the Closing Date, or (ii) on which a stop payment has been requested
by the deposit customer. Purchaser shall submit and file any required reports on
IRS Form 1099 with respect to interest accrued on Transferred Accounts after the
Closing Date. The provisions of this subsection 9.1 (a) shall in no way limit
Purchaser's duties or obligations arising under Paragraphs 1.3 and 1.4 hereof.

                                       20
<PAGE>   51

              (b) Purchaser shall, not earlier than ten days after the time of
procurement of all regulatory approvals required for consummation of the
transaction contemplated by this Agreement nor later than five days prior to the
Closing Date, notify all depositors of the Offices by letter, acceptable to
Seller, produced in, if appropriate, several similar, but different forms
calculated to provide necessary and specific information to the owners of
particular types of accounts, of Purchaser pending assumption of the Transferred
Accounts hereunder, and, in appropriate instances, notify depositors that on and
after the Closing Date certain Seller deposit-related services and/or Seller's
debit card and automatic teller machine services impacted by the transactions
contemplated by this Agreement, will be terminated. As an enclosure to such
notices, Purchaser may furnish appropriate depositors with brochures, forms and
other written materials related or necessary to the assumption of the Accounts
by Purchaser and the conversion of said accounts to Purchaser accounts,
including the provision of checks to appropriate depositors using the forms of
Purchaser with instructions to such depositors to utilize such Purchaser checks
on and after the Closing Date and thereafter to destroy any unused checks on
Seller's forms. The expenses of the printing, processing and mailing of such
letter notices and providing new Purchaser checks and other forms and written
materials to appropriate customers shall be borne by Purchaser. Before Closing,
except as provided in this paragraph, Purchaser will not contact Seller's
customers except as may occur in connection with advertising or solicitations
directed to the public generally or in the course of obtaining the requisite
regulatory approvals of the transaction. Anything to the contrary herein
notwithstanding, Purchaser shall provide, at no cost to Seller, any and all
notices, communications, and filings which may be required by law, regulation,
or otherwise, relating to any changes in terms and other matters relating to the
Accounts occurring subsequent to the Closing Date. Any and all such notices,
communications, and filings which may be required to be provided prior to the
Closing Date shall be submitted on a timely basis for review by Seller and shall
be subject to the written approval of Seller prior to delivery to any third
party. Purchaser shall provide, at its sole cost and expense and at no cost or
expense to Seller, that any and all customer and other notices, communications,
and filings provided by Purchaser hereunder, including the substance and timing
of same, fully comply with the requirements of applicable law and regulation.

              (c) Purchaser shall promptly pay to Seller an amount equivalent to
the amount of any checks, negotiable orders of withdrawal, drafts, withdrawal
orders, or returned items (net of the applicable Deposit Premium paid by
Purchaser with respect to the Transferred Accounts represented by any such
instrument) credited as of the close of business on the Closing Date to an
Account assumed by Purchaser hereunder which are returned uncollected to Seller
after the Closing Date. The foregoing shall include an amount equivalent to
holds placed upon such deposit account for items cashed by Seller as of the
close of business on the Closing Date.

              (d) Purchaser shall, not later than the close of business on the
business day immediately following the Closing Date, supply suitable
government-backed securities as security for any deposits of governmental units
included among the Transferred Accounts for which Seller had provided similar
security.

              (e) Purchaser hereby grants to Seller and its contractors access
to the Branch

                                       21
<PAGE>   52

Office until 8:00 A.M. local time on the day following the Transfer Date or such
other later date and time as the parties may agree, at no cost or expense to
Seller, for conduct of activities consistent with this Agreement in conjunction
with the transactions contemplated hereby.

              (f) The duties and obligations of Buyer in this Paragraph 9.1
shall survive the Closing.

         9.2  TRANSITIONAL ACTIONS BY SELLER. After the Closing, unless another
time is otherwise indicated:

              (a) Seller shall use its best efforts to cooperate with Purchaser
in assuring an orderly transition of ownership of the Assets and responsibility
for the liabilities, including the Transferred Accounts, assumed by Purchaser
hereunder. Seller shall provide final statements as of the Closing Date, in
conjunction with appropriate Transferred Accounts, with interest and service
charges pro-rated to close of business on the Closing Date. Seller shall submit
and file any required reports on IRS Form 1099 with respect to interest paid on
Transferred Accounts through the Closing Date. Notwithstanding the limitations
contained in 9.1(b), Seller shall, prior to issuing any notices to its customers
or the general public regarding the transaction contemplated by this Agreement,
obtain the prior written consent of Purchaser with respect to the content of
such notices. Purchaser shall not contact Seller's customers until the earlier
of (i) Seller's written consent, or (ii) receipt of all regulatory approvals and
the passage of any waiting periods, and all conditions precedent to Purchaser's
obligations hereunder have either been satisfied or waived in writing by
Purchaser.

              (b) Prior to the Closing Date, Seller shall cooperate with
Purchaser, at Purchaser's expense and at no expense to Seller, in making
Transferred Employees available at reasonable times for whatever program of
training Purchaser deems advisable; provided, however, that Purchaser shall
conduct such training program in a manner that does not materially interfere
with or prevent the performance of the normal duties and activities of such
Transferred Employees. Purchaser shall make request of Seller for training
opportunities prior to the Closing Date, and shall reimburse Seller at the
Closing for any and all costs relating to such training including, but not
limited to, regular and overtime salary for Transferred Employees involved in
training for the period of such training, travel costs, and all expenses
incurred by Seller or such Transferred Employees in conjunction with the
training. Such requests, which shall specify the time, duration and place of
such training, must be approved by Seller.

              (c) Seller shall cooperate with Purchaser, at no expense to
Seller, to make provision for the installation of teller and platform equipment
in the Branch Office subject to approval by Seller; provided, however, that
Purchaser shall arrange for the installation and placement of such equipment at
such times and in a manner that does not significantly interfere with the normal
business activities and operation of Seller or the Branch Office.

              (d) Seller shall resign as custodian of each IRA account
maintained at the Branch Office and assign the custodianship of such accounts to
Purchaser upon Closing subject to receipt of applicable customer consents and
other and analyze such provisions of this Agreement.

                                       22
<PAGE>   53

              (e) Seller shall terminate its ATM/debit card service effective as
of close of business on the business day preceding the Closing Date or such
other date and time as Seller and Purchaser may agree. Such terminations will be
preceded by the notice described in Paragraph 9.1(b) herein. Seller shall have
no obligation with respect to conversion or change over with respect to direct
deposit or payroll and retirement payments service relating to the Transferred
Accounts following the Closing and, further, Purchaser shall assume all
responsibility and liability with respect thereto following the Closing. Seller
will continue to redirect and/or pass through relevant ACH transactions on
Transferred Accounts for a period of two hundred ten (210) days following the
Closing Date.

              (f) As of the opening of business on the first business day after
the Closing Date, Seller and Purchaser shall provide the appropriate Federal
Reserve Bank (the "FRB") with all information necessary in order to expedite the
clearing and sorting of all checks, drafts, instruments and other commercial
paper relative to the Transferred Accounts (hereinafter collectively referred to
as "Paper Items"). Purchaser shall bear all charges and costs imposed by the
Federal Reserve in connection with the reassignment of account number ranges for
sorting the Paper Items.

              In the event the Federal Reserve and/or any other regional or
local clearinghouse for negotiable instruments fails, refuses or is unable to
direct sort such Paper Items for delivery to Purchaser with the result that such
Paper Items are presented to Seller, by not later than 3:00 p.m. local time on
each business day following the Closing and continuing for two hundred ten (210)
days after the Closing, Seller will make available to Purchaser for pick up from
Seller's offices or the offices of Seller's agent and/or processor at 47 West
Polk Street, Chicago, Illinois all of the Paper Items which are received by
Seller from the FRB and/or any regional or local clearinghouse during the
morning of each such business day on an "as-received basis." At the same time
Seller shall also make available to Purchaser information and records, including
but not limited to systems printouts, concerning such Paper Items and concerning
incoming Automated Clearing House items ("ACH items") as well as outstanding
Automatic Teller Machine ("ATM") transactions. Such information and records,
including but not limited to systems printouts, will utilize the most recent
account number designated by Seller for each of the Transferred Accounts.
Purchaser shall initiate appropriate Notification of Change requests relating to
appropriate routing matters at the sole expense of Purchaser within 30 days
following the Closing Date. Each business day Seller will endeavor to see that
the sum of (a) the actual Paper Items provided to Purchaser plus (b) all ACH
items and ATM transactions captured by Seller in its information and records
balance with the sum of (c) the information and records, including but not
limited to systems printouts, provided by Seller relative to the Paper Items
plus (d) the information and records, including but not limited to systems
printouts, provided relative to the ACH items and ATM transactions affecting the
Transferred Accounts.

              Except as otherwise expressly provided herein, Seller shall
provide the foregoing at no charge to Purchaser for a period not to exceed
thirty (30) days from the Closing Date except that Purchaser shall pay any
charges assessed to Seller by the FRB, a national or local clearinghouse and/or
Seller's agent and/or processor to the extent such assessments relate to the
Transferred

                                       23
<PAGE>   54

Accounts ("Costs"). Purchaser shall be responsible for pick up of the data to be
provided by Seller and shall compensate Seller for activity subsequent to the
referenced 30 day period as follows: (i) $50.00 per day and Seller's Costs plus
ten (10%) percent thereof for days 31 through 60; (ii) $50.00 per day and
Seller's Costs plus fifteen (15%) percent thereof for days 61 through 120; and
(iii) $50.00 per day and Seller's Costs plus twenty-five (25%) percent thereof
for days 121 through 180. Any request for extension of the 180-day period shall
be submitted in writing by Purchaser to Seller not later than 10 business days
prior to the expiration of such 180-day period or any extensions thereof and
shall be subject to approval by Seller at its sole discretion. Fees for activity
subsequent to the 180 day period shall be as determined by Seller. Fees for
activity subsequent to the initial 30-day period shall be assessed on a daily
basis and included in the daily cash settlement.

              Except as otherwise expressly provided herein, Purchaser shall be
responsible for processing any and all ACH returns, received subsequent to the
Closing, directly through the appropriate Federal Reserve Bank.

              Seller and Purchaser shall arrange for appropriate daily
settlement between the parties in order that the transmission of all monies
associated with the matters set forth in this Paragraph 9.2(f) might be effected
promptly.

              Seller shall not be liable to Purchaser for any failure to provide
the data required by this Paragraph 9.2(f) to the extent any such failure
results from causes beyond Seller's control including war, strike or other labor
disputes, acts of God, errors or failures of the FRB, and/or a participating
regional or local clearinghouse, or equipment failure or other emergency wherein
Seller and/or its agent processor has been unable to process in clearings from
the FRB or such clearinghouse.

              (g) Seller shall, not earlier than the time of procurement of all
regulatory approvals required for consummation of the transaction contemplated
by this Agreement nor later than twenty days prior to the Closing Date, notify
all depositors of the Branch Office by letter acceptable to Purchaser, produced
in, if appropriate, several similar, but different forms calculated to provide
necessary and specific information to the owners of particular types of accounts
and/or loans, of Purchaser's pending assumption of the Transferred Accounts,
and, in appropriate instances, notify depositors that on and after the Closing
Date certain Seller deposit-related services and/or Seller's debit card and
automatic teller machine services, will be terminated. The expenses of the
printing, processing and mailing of such letter notices shall be borne by
Seller. Anything to the contrary herein notwithstanding, nothing in this
Agreement shall be deemed to constitute an assumption by Seller of the duties
and obligations of Purchaser with respect to the provision of applicable
notices, communications, and filings relating to changes in the terms of any
Transferred Accounts as set forth in this Agreement.

              (h) The duties and obligations of the parties in this Paragraph
9.2 shall survive the Closing.

         9.3  OVERDRAFTS AND TRANSITIONAL ACTION. Overdrafts on the Transferred
Accounts up to

                                       24
<PAGE>   55

and including the date of Closing will be the responsibility and risk of Seller
and all fees associated therewith shall be the property of Seller. Overdrafts on
the Transferred Accounts after the date of Closing will be the responsibility
and risk of Purchaser and all fees associated therewith shall be the property of
Purchaser.

         9.4  ATM'S AND DEBIT CARDS.

         (a)  In accordance with the provisions of Section 4.7 hereinabove,
Seller shall provide to Purchaser and/or Purchaser's data processor, a test tape
no later than sixty (60) days prior to the closing date and a production tape no
later than thirty (30) days prior to the closing date so that Purchaser may
produce AB or CCB ATM/Debit cards with the same PIN number as the customer is
currently utilizing for their ATM/Debit card transactions prior to Closing. Both
tapes shall include file formats and/or file layouts of all ATM/Debit card
information and all related custumer information. Seller shall further provide
any and all information and assistance required by Purchaser as are reasonable
and customary in conversions of the kind contemplated by this Agreement. In
addition, from the date that the production tape is produced until the Data
Processing Conversion, Seller shall maintain, make available and deliver to
Purchaser a manual log of all new/replacement cards issued, changes to existing
cards/PIN numbers, and other such data so that Purchaser may make similar manual
changes to cards being produced for customers to be used after the date of the
Data Processing Conversion. Upon the Data Processing Conversion, Seller's Data
Processor shall deactivate the operation of the Seller's ATM/Debit cards with
respect to the Transferred Accounts. Purchaser and Seller agree to settle, on a
daily basis, the net amount of ATM debits/credits associated with transferred
accounts until the conversion date. Seller shall provide all necessary
information and reports with respect to such ATM/Debit card activity on the
Transferred Accounts so that Purchaser may appropriately debit/credit the
Transferred Accounts for such ATM/Debit card activity and balance sais activity
to the General Ledger or Settlement Accounts.

              (b     (c)  Purchaser and Seller agree to cooperate with each
other to assure that all transactions originated through the ATM or originated
with the ATM Cards prior to or on the Closing Date shall be for the account of
Seller and all transactions originated after the Closing Date shall be for the
account of Purchaser. A post closing adjustment shall be made to reflect all
such transactions, which cannot be reasonably calculated as of the Closing.

regulatory approvals have not been obtained prior December 1, 2000, (ii) by the

if any of the conditions provided in ARTICLE V shall not have been satisfied,

both Purchaser and Seller, as limited under the terms of this Agreement.

         If termination of this Agreement shall be judicially determined to have
been caused by breach of this Agreement by either party, then, in addition to
other remedies at law or equity for breach of this Agreement, breaching party
shall indemnify the other party for its costs, fees and expenses of its counsel,
accountants and other experts and advisors as well as fees and expenses incident
to negotiation, preparation and execution of this Agreement in related actions.
If termination of this Agreement shall be judicially determined to have been
caused by breach of this Agreement by either party, then the breaching party
shall pay promptly, and in any event within ten (10) days of receipt of written
notice from the other party, to the other party TWO HUNDRED THOUSAND AND
NO/100THS ($200,000.00) DOLLARS plus the other party's costs, fees and expenses

         11.1 A. NON-SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.
None of the representations or warranties and agreements in this Agreement or in

<PAGE>   57

contained to the contrary it is agreed that all insurance coverage relating to
claims arising from Seller's administration of the Transferred Accounts prior to
the Closing Date shall, to the extent assignable, be assigned to Purchaser. To
the extent such insurance claims are either a) not transferable or b) not
otherwise covered by any insurance, then Seller agrees to indemnify, defend, and
hold Purchaser harmless from any losses, judgments, expenses, attorneys fees or
costs threatened or incurred by Purchaser as a result of such claims, provided,
however, that Seller shall not indemnify, defend or hold Purchaser harmless from
Purchaser's own negligence or willful misconduct.

hereunder shall be in writing and may be delivered via facsimile transmission,

<PAGE>   62

and in consideration of the representations, warranties, covenants, terms and
conditions set forth herein, Purchaser and Seller hereby covenant and agree as
follows:

                                    ARTICLE I
               TRANSFER/ASSUMPTION OF ACCOUNTS, ASSETS AND LEASES

         1.1  IDENTIFICATION OF ACCOUNTS BY OFFICE LOCATION. Seller shall
transfer to Purchaser certain of its deposit accounts, including demand deposit
accounts, regular savings accounts, money market accounts, certificates of
deposit, all public funds accounts and negotiable order of withdrawal accounts,
as more fully set forth and described in Paragraph 2 hereof (hereinafter
sometimes for convenience collectively referred to as the "Accounts" or the
"Transferred Accounts"); with the said Accounts generally originating at and
attributable to the Branch Office except that Seller shall not transfer to and
Purchaser shall not assume liability for any brokered accounts (deposits
originated by a third party other than the deposit-holder), Accounts owned by
affiliates, directors, officers and/or employees of Seller who do not work at
the Branch Office.

         1.2  IDENTIFICATION OF TRANSFERRED ACCOUNTS BY EXHIBIT. Marked Schedule
1.2, attached hereto and specifically incorporated herein by this reference, is
a verified statement prepared and submitted in a form substantially similar in
format to previous reports tendered by Seller setting forth the identity of
holder, the type of account, account opening date, account maturity date,
principal balance (including accrued and credited interest of such account), and
interest rate payable on each of the Transferred Accounts as of July 31, 2000.
Seller shall also provide, or make available, to Purchaser such other account
information as may be required for legitimate business purposes. After the close
of business on the day preceding the Closing Date (as defined in Article VI
hereof), Seller hereby agrees to deliver to Purchaser a supplemental statement
verifying the information set forth in the preceding sentence together with such
information with respect to any new or additional accounts opened after August
1, 2000 on each of the Accounts to be transferred to Purchaser as of the date
three (3) days prior to the Closing Date (such 3-day period the "Gap Period") as
well as an identification of any accounts which were closed between the date of
the original Schedule 1.2 and Supplemental Schedule 1.2. A Post-closing Schedule
1.2 covering the Gap Period shall be delivered by Seller to Purchaser within ten
(10) days of the Closing Date. Any adjustment to the Purchase Price (as defined
in Paragraph 1.6) based upon a difference between the Supplemental Schedule 1.2
and the Post-Closing Schedule 1.2 shall be paid by a party to the other party
within five (5) business days following delivery of the Post-Closing Schedule
1.2 to Purchaser. The form and substance of the statements referenced in this
paragraph shall be to the reasonable satisfaction of Purchaser and shall include
such information as necessary to identify the ownership and total liability of
such Accounts. For the purposes of this Agreement any interest accrued on the
Transferred Accounts by Seller, but not due for payment as of the Closing Date,
shall be transferred to Purchaser in current funds pursuant to Paragraph 1.4
hereof, and Purchaser shall thereupon assume the liability therefor.

         1.3  TRANSFER. Purchaser shall assume the liability for and thereafter
discharge, pay in full and perform all of Seller's obligations and duties
related to such Transferred Accounts as of the Closing Date subject to the terms
and conditions of this Agreement. Purchaser and Seller hereby

<PAGE>   63

agree that performance of this Agreement shall be subject to receipt of all
necessary regulatory approvals as set forth in this Agreement.

         1.4  ASSUMPTION OF LIABILITY ON TRANSFERRED ACCOUNTS. Purchaser will
receive, for the assumption of liability on the Transferred Accounts (including
interest previously credited in accordance with the terms of the account and
interest accrued to the Closing Date), a cash payment at Closing equal to the

on the Transferred Accounts but not due for payment or credited to the account
as of the Closing Date.

         1.5  ACCOUNT HOLDERS. Each holder of a Transferred Account of Seller
shall, after the close of business on the Closing Date, automatically become a
holder of an Account in Purchaser, in a dollar amount equal to the withdraw able
value of the Account, Purchaser having assumed the liability for the Transferred
Accounts subject to the indemnification provisions contained herein and the
existing rights, delegations, assignments, appointments, powers of appointment
and privileges of the Account holders. Thereafter, each such account holder
shall be entitled to all of the rights and privileges of an account holder of
Purchaser, as prescribed by its Articles of Incorporation, Bylaws and account
rules and, when appropriate, be issued proper account documentation evidencing
such account in Purchaser. Purchaser shall continue to recognize the terms and
maturities of all of the transferred accounts as of the Closing Date until the
originally stated maturity date. Thereafter, such accounts shall be renewed upon
the terms of Purchaser for similar accounts. Purchaser shall be responsible for
all regulatory filings and for the issuance of Forms 1098 and 1099 for all
periods ending after the Closing Date. Seller shall be responsible for all
regulatory filings and for the issuance of forms 1098 and 1099 for all periods
prior to the Closing Date.

         1.6  CONSIDERATION FOR TRANSFERRED ACCOUNTS. For and in consideration
of the transfer by Seller to Purchaser of the aggregate account balance of and
the accrued interest on the Transferred Accounts, Purchaser agrees to pay to
Seller on the Closing Date, a purchase price (the "Purchase Price" or "Deposit
Premium") equal to (a) eight and ninety-nine one hundredths percent (8.99%) on
the aggregate account balance of the core deposit Transferred Accounts and (b)
2% on the account balance of the public funds as defined in paragraph 1 and as
identified on the Schedules to Paragraph 1.2, SAID DEPOSIT PREMIUM ON PUBLIC
FUNDS TO BE PAID ON PUBLIC FUNDS NOT EXCEEDING A MAXIMUM OF $1,600,720. Any
public funds on deposit at the Branch Office in excess of $1,600,720 as of the
Closing Date shall be removed by Seller. The Purchase Price may be adjusted in
accordance with the provisions of Paragraph 1.2 hereof.

         1.7  ACQUISITION OF FURNITURE, FIXTURES AND EQUIPMENT. Schedule 1.7,
attached hereto and specifically incorporated herein by this reference is a
preliminary schedule of the Assets presently located at the Branch Office, along
with said assets net book value as of July 31, 2000, which Seller agrees to
transfer to Purchaser at Closing for a price equal to the net book value thereof
as of the Closing Date. A final listing of specific items included in the Assets
and their then current net book value will be provided to Purchaser prior to the
Closing. Seller shall transfer its ownership of such Assets to Purchaser by a
duly authorized Bill of Sale. Such sale shall be "as is", and Seller makes no

warranties whatsoever except those set forth herein at Paragraph 2.14.

after the Closing. Seller shall pay all Lease obligations to the Closing Date,
and shall be entitled to credit at Closing for prepaid rent and for its security
deposit. Notwithstanding anything contained herein to the contrary, Purchaser's
performance of its obligations hereunder is specifically conditioned on its
ability to procure an assignment of the Lease under the same terms and
conditions as are currently contained therein.

         1.9  ASSIGNMENT OF CONTRACTS. Seller agrees to assign to Purchaser, and
Purchaser agrees to assume, subject to the terms hereof, all of Seller's rights

         Seller represents and warrants to Purchaser the following statements of
Essential Facts, which are true and correct on the date of this Agreement and
which shall be true and correct on the Closing Date, and of each of which shall
constitute a condition precedent to Purchaser's obligations hereunder:

enter into this Agreement and to carry out the transactions contemplated to be
carried out by it. This Agreement has been duly executed and delivered by Seller
and constitutes the legal, valid and binding obligation of Seller enforceable in
accordance with its terms.

         2.3  NO MATERIAL CHANGE AFTER AGREEMENT. Until the transaction is
effective, Seller will conduct its operations related to the Branch Office and
to the Transferred Accounts hereunder in accordance with all applicable laws,
regulations, orders of regulatory authorities and in accordance with sound
business and past practices. Furthermore, between the date hereof and the
Closing provided for herein, unless otherwise agreed in writing, Seller shall
use its best efforts to maintain and preserve its business organization intact,
and to maintain its relationships and goodwill with the account holders,
employees and others having business relationships related to the Branch Office
and to the Accounts and the Assets which are the subject of this Agreement.
Seller will neither enter into nor materially amend any agreements related to
the operation of the Branch Office and will not offer a premium rate of interest
or increase its current deposit rates of interest to attract or maintain
deposits without the prior written consent of Purchaser, which consent may be
withheld by Purchaser in its sole discretion, nor artificially inflate the
aggregate account balances of the Transferred Accounts prior to Closing.
Notwithstanding anything contained herein to the contrary, Seller shall provide
Purchaser, on a weekly basis, with a report detailing new and renewed interest
bearing deposit accounts. Seller shall not invest in any Assets for the Branch
Office, except for replacements of furniture, furnishings and equipment and
normal maintenance made in the ordinary course of Branch Office business.
Notwithstanding the foregoing, Seller shall not make any expenditures in excess
of $10,000 for purchase or replacement of said assets without the written
consent of Purchaser, which consent shall not be unreasonably withheld. Seller
will not hire (other than to replace a departing employee and/or bring the
number of employees at the Branch Office to a normal staffing level), transfer,
reassign or terminate any employee of the Branch Office, increase the
compensation of any employee of the Branch Office, or promote any of the
employees of the Branch Office except pursuant to and consistent with Seller's
customary policies and procedures.

         2.4  STANDSTILL. Seller will not, directly or indirectly, make,
encourage, facilitate, solicit, assist or initiate any inquiry, proposal or
offer to or by, or provide any information to or participate in any negotiations
with any other party related to a liquidation, consolidation, sale, purchase or
assumption related to the Branch Office or the Assets or the Accounts,
participate in any discussions or negotiations regarding the same, furnish any
information with respect to the same, assist or participate in, or facilitate in
any other manner any effort or attempt by any person to do or seek any of the
foregoing, or make any agreement with respect to or engage in any of the
foregoing anytime prior to December 31, 2000, unless this Agreement is
terminated prior to December 31, 2000.

         2.5  LITIGATION. There are no claims, demands, orders, actions, suits,
proceedings or other litigation (nor does Seller know of any investigation
preliminary thereto) of any nature pending or to the knowledge of Seller
threatened against Seller, related to the Accounts, the Assets or the Branch

                                       5

Office, at law or in equity, before or by any Federal, State, municipal or other
court, governmental department, commission, board, bureau, agency or
instrumentality; there is no default existing or penalty incurred under any
agreement or obligation of or binding upon Seller nor is Seller aware of any
facts that could reasonably afford a basis for a cause of action against Seller.

fees incurred as a result of this transaction shall be borne exclusively by
Seller, neither Seller nor any of its respective officers or directors has

person or paid or agreed to pay any fee or commission to any agent, broker,
finder or other such person for or on account of this Agreement or the
transactions contemplated hereby.

hereto, statement, list, certificate or other information furnished or to be
furnished in writing by Seller to Purchaser in connection with this Agreement or
any of the transactions contemplated hereby contains or will contain an untrue
statement of a material fact or omits or will omit to state a material fact
necessary to make the statements contained herein or therein, taken as a whole
with all other such statements, lists, certificates or other information
furnished above in light of the circumstances in which they are made, not
misleading.

         2.8  NO VIOLATION. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby will not violate or result
in a breach by Seller of, or constitute a default under, or conflict with, or
cause any acceleration of any obligation with respect to: any provision or
restriction of any charter, bylaw, loan or indenture of Seller or any provision
or restriction of any lien, lease agreement, contract, instrument, order,
judgment, award, decree, ordinance or regulation or any other restriction of any
kind or character to which any assets or properties of Seller are subject or by
which Seller is bound.

         2.9  DISASTER PROVISION. The business and properties of the Branch
Office shall not have been adversely affected in any material way as a result of

all action reasonably necessary to enable it to fulfill when due all material
obligations under the Contracts; and there are no material defaults and no
events have occurred that, with the lapse of time or election of any other
party, will become material defaults by it under any of the Contracts.

election by such Leave Employees to return to work with Purchaser. From and
after the Closing Date, Purchaser shall pay, discharge, and be responsible for
all salary, wages, and benefits arising out of or relating to the employment of
the Transferred Employees by Purchaser from and after the Closing Date,
including, without limitation, all claims for welfare benefits plans incurred on
or after the Closing Date. Claims are incurred as of the date services are
provided notwithstanding when the injury or illness may have occurred. To the
extent permitted under Purchaser's applicable 401 (k) plan, Seller and Purchaser
shall cooperate in arranging for the transfer to Purchaser's 401 (k) plan, as
soon as practicable after the Closing Date and in a manner that satisfies
sections 414(1) and 411 (d)(6) of the Internal Revenue Code, as amended, of
those accounts held under Seller's 401 (k) plan on behalf of Transferred
Employees.

         7.3  COMPLIANCE WITH LAW. Purchaser agrees that it shall comply with
any and all applicable requirements, if any, under the Worker Adjustment and
Retraining Notification Act in connection with the transaction contemplated by
this Agreement. Purchaser hereby agrees to indemnify and to hold Seller and its
affiliates and its and their officers, directors, agents, and employees harmless
from and against any and all liability, loss, cost, and expense, however
arising, as a result of the failure of Purchaser to comply with its obligations
as set forth in this section.

         7.4  ACTIONS TO BE TAKEN BY SELLER. Seller covenants to Purchaser that
it will do or cause the following to occur:

         (a)  COVENANT NOT TO COMPETE. Seller [and John G. Yedinak,
individually] shall not, directly or indirectly, by or through any of its
directors, officers, employees, agents or subsidiaries, solicit deposits, market
any of its financial services (except for the existing mortgage and mortgage
purchase and resale business it currently operates under the name of "Margo
Financial Services", hereinafter "Margo") or engage in any retail banking or
provide financial services that are in direct competition with the business of
Purchaser, for a period of five (5) years within the Market Area of the Branch
whose business is being transferred under this Agreement [Market Area being
defined for the purposes of this Agreement to be within a radius of ten (10)
miles from 8627 S. Roberts Road, Bridgeview, Illinois]; EXCEPT that any area
within said ten mile radius which falls west of I-294 and north of I-55 and
South of I-88, shall be deemed to be outside of the Market Area for the
purposes

                                       17
<PAGE>   78

of this Covenant not to Compete. Notwithstanding the foregoing it is understood
and agreed that Seller shall change its name to "Umbrellabank" or
"Umbrellabank.com" or such other name which is not similar to "Argo" as soon
after the Closing of this transaction as the required regulatory approvals for
such a name change can be secured [Seller shall apply for said approval(s)
within thirty (30) days after the closing and provide Purchaser with evidence of
said application] and to continue to provide banking and related services
outside of the Market Area and conduct an electronic banking business under the
name of "Umbrellabank.com" both within and outside of the Market Area and that
said electronic banking business shall be exempt from the provisions of this
Covenant not to Compete PROVIDED that the marketing of said Umbrellabank.com's
services shall not be specifically targeted to the Market Area or the customers
of Seller whose accounts are being transferred to Purchaser under this Agreement
and that the name of "Argo Federal Savings Bank" is not used in connection with
any marketing of Umbrellabank.com's or Seller's services in the Market Area
during the term of this Covenant not to Compete (except to the extent that
banking regulations require the screen on Seller's Automated Teller Machines
("ATM's") to identify Umbrellabank as a "division of Argo Federal Savings Bank"
or to otherwise comply with banking regulations). Seller shall not install any
ATM's within the Market Area (as defined hereinabove) during the term of this
Covenant, except that in the event that Seller is obligated under any existing
(or future) contracts to install ATMs within the Market Area during the term of
the Covenant not to Compete, Purchaser shall have a right of first refusal to
license each such additional ATM installed, such right of first refusal to be
expressly exercised by Purchaser in a writing delivered to Seller within ten
(10) days of receipt of written notice thereof by Seller. If Purchaser exercises
said right of first refusal, Purchaser shall reimburse Seller for Seller's costs
of installing said ATM, including the cost of the ATM, labor and installation
charges and signage [the design and content of said signage to be reasonably
acceptable to Purchaser], and shall pay a monthly fee to the Seller based on
transaction volume at the rate of twenty ($0.20) cents per transaction. If
Purchaser declines to exercise said right of first refusal as provided herein,
Seller shall have the right to install such ATM(s) subject to the restrictions
contained herein concerning the use of the name "Argo" on said ATM(s).

         Notwithstanding the provisions contained herein to the contrary, it is
understood that Seller shall continue to operate its existing branches located
at 14076 Lincoln Avenue, Dolton, Illinois, 2154 West Madison Street, Chicago,
Illinois, 47 West Polk Street, Chicago, Illinois (to the extent that said branch
is not sold to an affiliate of Purchaser) and at site to be located within a one
(1) mile radius of the intersection of Chicago Avenue and Halsted Street in
Chicago, Illinois or any other location outside the Market Area, under its
existing name until the name change referred to hereinabove shall be approved
(and thereafter under its name as so changed) and that the continued operation
of said branches by Seller shall not constitute a breach of the Covenant not to
Compete provided that the services of said branches shall not be specifically
targeted to the Market Area or the customers of Seller whose accounts are being
transferred to Purchaser under this Agreement. In addition, it is agreed that
Seller may maintain its corporate offices and the office of "Margo" at their
present location at 5818 Archer Road, Summit, Illinois subject to the
restrictions contained in this Covenant not to Compete.

         It is further agreed that in the event that Seller, or any entity in
which John G. Yedinak

                                       18
<PAGE>   79

(hereinafter "Yedinak") is an officer, director or employee, shall seek to
acquire any financial institution which is located outside of the Market Area
during the term of this Covenant not to Compete, but which institution has a
branch located within the Market Area, Purchaser shall have a right of first
refusal with respect to any such branch(es) as may be located within the Market
Area, to be exercised by Purchaser in writing within thirty (30) days after
receiving written notice from Seller and/or Yedinak, which notice shall contain
all of the terms and conditions of said proposed acquisition and the usual and
customary information and opportunity required by a Purchaser to conduct due
diligence.

         (b) ENFORCEABILITY. The parties believe that the restrictive covenants
contained in this paragraph are reasonable. However, if any court of competent
jurisdiction subsequently holds these restrictions to be unreasonable, whether
as to scope, territory, or period of time specified herein, such scope,
territory, or period of time shall be deemed to be that which the court shall
declare or deem to be reasonable.

         (c) INJUNCTIVE RELIEF. Seller recognizes that Purchaser may suffer
irreparable damage if the terms of this restrictive covenant are violated, and
that it will be difficult, if not impossible, to compute Purchaser's actual
damages resulting from such unauthorized competition. The parties therefore
agree that Purchaser may apply to a court of competent jurisdiction to enjoin
any threatened or actual breach of the covenants contained herein, and that the
prevailing party in any ensuing action shall be entitled to recover its
reasonable expenses, including court costs and reasonable attorney's fees.

         (d) SOLICITATION OF TRANSFERRED EMPLOYEES. Except with the written
consent of Purchaser, for a period of eighteen (18) months following the Closing
Date, Seller will not, directly or indirectly, solicit Transferred Employees as
prospective officers or employees of Seller; provided, however, that Seller
shall not be prohibited or restricted from hiring a Transferred Employee if such
Transferred Employee is terminated by Purchaser. Notwithstanding anything herein
to the contrary, it is agreed that any transferred Employee who is hired by
Seller after the Closing Date, shall be bound by the terms of the Covenant not
to Compete herein above set forth by virtue of their employment by Seller.

         (e) EMPLOYEE BENEFIT PROGRAMS. Seller's obligations to employees of the
Branch Office, including Transferred Employees, will be as set forth in
established policies of Seller, and Seller shall continue its employee benefit
programs in full force and effect as benefit programs for Transferred Employees
through the Closing Date. After the Closing, Seller shall retain the
responsibility and liability for the funding and payment of all claims incurred
under such employee benefit programs through the Closing Date. Purchaser shall
have no obligation or liability to compensate Transferred Employees for benefits
of any kind earned, accrued, promised and/or provided to Transferred Employees
as employees of Seller, except with respect to eligibility and vesting as set
forth in Paragraph 7.2 above.

         (f) EMPLOYEES OF THE BRANCH OFFICE. Seller shall not, without
Purchaser's prior written

                                       19
<PAGE>   80

consent (i) increase the aggregate full-time equivalent size of the work force
at the Branch Office above the aggregate normal staffing levels designated by
Seller for the Branch Office at the date hereof, (ii) terminate any Transferred
Employee prior to the Closing Date, unless such person is terminated for cause
as determined at the sole discretion of Seller or otherwise pursuant to existing
Seller policies or procedures, or (iii) increase the compensation of any
Transferred Employee except pursuant to existing Seller policies and procedures.

         The obligations of Seller and Purchaser pursuant to this ARTICLE VII
shall survive the Closing.

                                  ARTICLE VIII
                              ADDITIONAL AGREEMENTS

         8.1  COOPERATION. Purchaser and Seller further covenant and agree that
each shall cooperate in expeditiously obtaining all necessary or appropriate
governmental approvals, consents or permits and in preparing any and all
applications contemplated by this Agreement, and will furnish such supporting
information or exhibits as may be required, and will not do, sanction or
knowingly permit any person under the control of each to do anything which might
in any way hinder, delay or prevent the expeditious approval of the transactions
contemplated by this Agreement or the orderly transition of Seller's customers
to Purchaser, or commit any act or omission which might be reasonably expected
to have such an effect.

         8.2  CONFIDENTIALITY. Purchaser and Seller each agree to keep
confidential all information, documents, books, records and any other material
no matter how obtained from the other party hereto unless and until the
transaction contemplated herein is consummated, and if such transaction is not
consummated, each party hereto will return or cause to be returned to the
applicable party all such documents, material and information then in its
possession, or the possession of a representative of either, and neither party
hereto will divulge or use such information until it becomes known generally to
the public.
                                   ARTICLE IX
                              TRANSITIONAL MATTERS

         9.1  TRANSITIONAL ACTION BY PURCHASER. After the Closing, unless
another time is otherwise indicated:

              (a) Purchaser shall: (i) pay in accordance with the law and
customary banking practices and applicable Account contract terms, all properly
drawn and presented checks, negotiable orders of withdrawal, drafts, debits, and
withdrawal orders presented to Purchaser by mail, over the counter, through
electronic media, or through the check clearing system of the banking industry,
by depositors of the Transferred Accounts assumed by Purchaser hereunder,
whether drawn on checks, negotiable orders or withdrawal, drafts, or withdrawal
order forms provided by Purchaser or Seller; and (ii) in all other respects
discharge, in the usual course of the banking business, the duties and
obligations of Seller with respect to the balances due and owing to the
depositors whose Accounts

                                       20
<PAGE>   81

are assumed by Purchaser hereunder; provided, however, that any obligations of
Purchaser pursuant to this Paragraph 9.1 to honor checks, negotiable orders of
withdrawal, drafts, and withdrawal orders on forms provided by Seller and
carrying its imprint (including its name and transit routing number) shall not
apply to any checks, drafts, withdrawal orders, or returned items (i) presented
to Purchaser more than two hundred ten (210) days following the Closing Date, or
(ii) on which a stop payment has been requested by the deposit customer.
Purchaser shall submit and file any required reports on IRS Form 1099 with
respect to interest accrued on Transferred Accounts after the Closing Date. The
provisions of this subsection 9.1 (a) shall in no way limit Purchaser's duties
or obligations arising under Paragraphs 1.3 and 1.4 hereof.

              (b) Purchaser shall, not earlier than ten days after the time of
procurement of all regulatory approvals required for consummation of the
transaction contemplated by this Agreement nor later than five days prior to the
Closing Date, notify all depositors of the Offices by letter, acceptable to
Seller, produced in, if appropriate, several similar, but different forms
calculated to provide necessary and specific information to the owners of
particular types of accounts, of Purchaser pending assumption of the Transferred
Accounts hereunder, and, in appropriate instances, notify depositors that on and
after the Closing Date certain Seller deposit-related services and/or Seller's
debit card and automatic teller machine services impacted by the transactions
contemplated by this Agreement, will be terminated. As an enclosure to such
notices, Purchaser may furnish appropriate depositors with brochures, forms and
other written materials related or necessary to the assumption of the Accounts
by Purchaser and the conversion of said accounts to Purchaser accounts,
including the provision of checks to appropriate depositors using the forms of
Purchaser with instructions to such depositors to utilize such Purchaser checks
on and after the Closing Date and thereafter to destroy any unused checks on
Seller's forms. The expenses of the printing, processing and mailing of such
letter notices and providing new Purchaser checks and other forms and written
materials to appropriate customers shall be borne by Purchaser. Before Closing,
except as provided in this paragraph, Purchaser will not contact Seller's
customers except as may occur in connection with advertising or solicitations
directed to the public generally or in the course of obtaining the requisite
regulatory approvals of the transaction. Anything to the contrary herein
notwithstanding, Purchaser shall provide, at no cost to Seller, any and all
notices, communications, and filings which may be required by law, regulation,
or otherwise, relating to any changes in terms and other matters relating to the
Accounts occurring subsequent to the Closing Date. Any and all such notices,
communications, and filings which may be required to be provided prior to the
Closing Date shall be submitted on a timely basis for review by Seller and shall
be subject to the written approval of Seller prior to delivery to any third
party. Purchaser shall provide, at its sole cost and expense and at no cost or
expense to Seller, that any and all customer and other notices, communications,
and filings provided by Purchaser hereunder, including the substance and timing
of same, fully comply with the requirements of applicable law and regulation.

              (c) Purchaser shall promptly pay to Seller an amount equivalent to
the amount of any checks, negotiable orders of withdrawal, drafts, withdrawal
orders, or returned items (net of the applicable Deposit Premium paid by
Purchaser with respect to the Transferred Accounts represented by any such
instrument) credited as of the close of business on the Closing Date to an

                                       21
<PAGE>   82

Account assumed by Purchaser hereunder which are returned uncollected to Seller
after the Closing Date. The foregoing shall include an amount equivalent to
holds placed upon such deposit account for items cashed by Seller as of the
close of business on the Closing Date.

              (d) Purchaser shall, not later than the close of business on the
business day immediately following the Closing Date, supply suitable
government-backed securities as security for any deposits of governmental units
included among the Transferred Accounts for which Seller had provided similar
security.

              (e) Purchaser hereby grants to Seller and its contractors access
to the Branch Office until 8:00 A.M. local time on the day following the
Transfer Date or such other later date and time as the parties may agree, at no
cost or expense to Seller, for conduct of activities consistent with this
Agreement in conjunction with the transactions contemplated hereby.

              (f) The duties and obligations of Buyer in this Paragraph 9.1
shall survive the Closing.

         9.2  TRANSITIONAL ACTIONS BY SELLER. After the Closing, unless another
time is otherwise indicated:

              (a) Seller shall use its best efforts to cooperate with Purchaser
in assuring an orderly transition of ownership of the Assets and responsibility
for the liabilities, including the Transferred Accounts, assumed by Purchaser
hereunder. Seller shall provide final statements as of the Closing Date, in
conjunction with appropriate Transferred Accounts, with interest and service
charges pro-rated to close of business on the Closing Date. Seller shall submit
and file any required reports on IRS Form 1099 with respect to interest paid on
Transferred Accounts through the Closing Date. Notwithstanding the limitations
contained in 9.1(b), Seller shall, prior to issuing any notices to its customers
or the general public regarding the transaction contemplated by this Agreement,
obtain the prior written consent of Purchaser with respect to the content of
such notices. Purchaser shall not contact Seller's customers until the earlier
of (i) Seller's written consent, or (ii) receipt of all regulatory approvals and
the passage of any waiting periods, and all conditions precedent to Purchaser's
obligations hereunder have either been satisfied or waived in writing by
Purchaser.

              (b) Prior to the Closing Date, Seller shall cooperate with
Purchaser, at Purchaser's expense and at no expense to Seller, in making
Transferred Employees available at reasonable times for whatever program of
training Purchaser deems advisable; provided, however, that Purchaser shall
conduct such training program in a manner that does not materially interfere
with or prevent the performance of the normal duties and activities of such
Transferred Employees. Purchaser shall make request of Seller for training
opportunities prior to the Closing Date, and shall reimburse Seller at the
Closing for any and all costs relating to such training including, but not
limited to, regular and overtime salary for Transferred Employees involved in
training for the period of such training, travel costs, and all expenses
incurred by Seller or such Transferred Employees in conjunction with the
training. Such requests, which shall specify the time, duration and place of
such training, must be

                                       22
<PAGE>   83

approved by Seller.

              (c) Seller shall cooperate with Purchaser, at no expense to
Seller, to make provision for the installation of teller and platform equipment
in the Branch Office subject to approval by Seller; provided, however, that
Purchaser shall arrange for the installation and placement of such equipment at
such times and in a manner that does not significantly interfere with the normal
business activities and operation of Seller or the Branch Office.

              (d) Seller shall resign as custodian of each IRA account
maintained at the Branch Office and assign the custodianship of such accounts to
Purchaser upon Closing subject to receipt of applicable customer consents and
other and analyze such provisions of this Agreement.

              (e) Seller shall terminate its ATM/debit card service effective as
of close of business on the business day preceding the Closing Date or such
other date and time as Seller and Purchaser may agree. Such terminations will be
preceded by the notice described in Paragraph 9.1(b) herein. Seller shall have
no obligation with respect to conversion or change over with respect to direct
deposit or payroll and retirement payments service relating to the Transferred
Accounts following the Closing and, further, Purchaser shall assume all
responsibility and liability with respect thereto following the Closing. Seller
will continue to redirect and/or pass through relevant ACH transactions on
Transferred Accounts for a period of two hundred ten (210) days following the
Closing Date.

              (f) As of the opening of business on the first business day after
the Closing Date, Seller and Purchaser shall provide the appropriate Federal
Reserve Bank (the "FRB") with all information necessary in order to expedite the
clearing and sorting of all checks, drafts, instruments and other commercial
paper relative to the Transferred Accounts (hereinafter collectively referred to
as "Paper Items"). Purchaser shall bear all charges and costs imposed by the
Federal Reserve in connection with the reassignment of account number ranges for
sorting the Paper Items.

              In the event the Federal Reserve and/or any other regional or
local clearinghouse for negotiable instruments fails, refuses or is unable to
direct sort such Paper Items for delivery to Purchaser with the result that such
Paper Items are presented to Seller, by not later than 3:00 p.m. local time on
each business day following the Closing and continuing for two hundred ten (210)
days after the Closing, Seller will make available to Purchaser for pick up from
Seller's offices or the offices of Seller's agent and/or processor at 8627 S.
Roberts Road, Bridgeview, Illinois all of the Paper Items which are received by
Seller from the FRB and/or any regional or local clearinghouse during the
morning of each such business day on an "as-received basis." At the same time
Seller shall also make available to Purchaser information and records, including
but not limited to systems printouts, concerning such Paper Items and concerning
incoming Automated Clearing House items ("ACH items") as well as outstanding
Automatic Teller Machine ("ATM") transactions. Such information and records,
including but not limited to systems printouts, will utilize the most recent
account number designated by Seller for each of the Transferred Accounts.
Purchaser shall initiate appropriate Notification of Change requests relating to
appropriate routing matters at the sole

                                       23
<PAGE>   84

expense of Purchaser within 30 days following the Closing Date. Each business
day Seller will endeavor to see that the sum of (a) the actual Paper Items
provided to Purchaser plus (b) all ACH items and ATM transactions captured by
Seller in its information and records balance with the sum of (c) the
information and records, including but not limited to systems printouts,
provided by Seller relative to the Paper Items plus (d) the information and
records, including but not limited to systems printouts, provided relative to
the ACH items and ATM transactions affecting the Transferred Accounts.

              Except as otherwise expressly provided herein, Seller shall
provide the foregoing at no charge to Purchaser for a period not to exceed
thirty (30) days from the Closing Date except that Purchaser shall pay any
charges assessed to Seller by the FRB, a national or local clearinghouse and/or
Seller's agent and/or processor to the extent such assessments relate to the
Transferred Accounts ("Costs"). Purchaser shall be responsible for pick up of
the data to be provided by Seller and shall compensate Seller for activity
subsequent to the referenced 30 day period as follows: (i) $50.00 per day and
Seller's Costs plus ten (10%) percent thereof for days 31 through 60; (ii)
$50.00 per day and Seller's Costs plus fifteen (15%) percent thereof for days 61
through 120; and (iii) $50.00 per day and Seller's Costs plus twenty-five (25%)
percent thereof for days 121 through 180. Any request for extension of the
180-day period shall be submitted in writing by Purchaser to Seller not later
than 10 business days prior to the expiration of such 180-day period or any
extensions thereof and shall be subject to approval by Seller at its sole
discretion. Fees for activity subsequent to the 180 day period shall be as
determined by Seller. Fees for activity subsequent to the initial 30-day period
shall be assessed on a daily basis and included in the daily cash settlement.

              Except as otherwise expressly provided herein, Purchaser shall be
responsible for processing any and all ACH returns, received subsequent to the
Closing, directly through the appropriate Federal Reserve Bank.

              Seller and Purchaser shall arrange for appropriate daily
settlement between the parties in order that the transmission of all monies
associated with the matters set forth in this Paragraph 9.2(f) might be effected
promptly.

              Seller shall not be liable to Purchaser for any failure to provide
the data required by this Paragraph 9.2(f) to the extent any such failure
results from causes beyond Seller's control including war, strike or other labor
disputes, acts of God, errors or failures of the FRB, and/or a participating
regional or local clearinghouse, or equipment failure or other emergency wherein
Seller and/or its agent processor has been unable to process in clearings from
the FRB or such clearinghouse.

              (g) Seller shall, not earlier than the time of procurement of all
regulatory approvals required for consummation of the transaction contemplated
by this Agreement nor later than twenty days prior to the Closing Date, notify
all depositors of the Branch Office by letter acceptable to Purchaser, produced
in, if appropriate, several similar, but different forms calculated to provide
necessary and specific information to the owners of particular types of accounts
and/or

                                       24
<PAGE>   85

loans, of Purchaser's pending assumption of the Transferred Accounts, and, in
appropriate instances, notify depositors that on and after the Closing Date
certain Seller deposit-related services and/or Seller's debit card and automatic
teller machine services, will be terminated. The expenses of the printing,
processing and mailing of such letter notices shall be borne by Seller. Anything
to the contrary herein notwithstanding, nothing in this Agreement shall be
deemed to constitute an assumption by Seller of the duties and obligations of
Purchaser with respect to the provision of applicable notices, communications,
and filings relating to changes in the terms of any Transferred Accounts as set
forth in this Agreement.

              (h) The duties and obligations of the parties in this Paragraph
9.2 shall survive the Closing.

         9.3  OVERDRAFTS AND TRANSITIONAL ACTION. Overdrafts on the Transferred
Accounts up to and including the date of Closing will be the responsibility and
risk of Seller and all fees associated therewith shall be the property of
Seller. Overdrafts on the Transferred Accounts after the date of Closing will be
the responsibility and risk of Purchaser and all fees associated therewith shall
be the property of Purchaser.

         9.4  ATM'S AND DEBIT CARDS.

         (a)  In accordance with the provisions of Section 4.7 hereinabove,
Seller shall provide to Purchaser and/or Purchaser's data processor, a test tape
no later than sixty (60) days prior to the closing date and a production tape no
later than thirty (30) days prior to the closing date so that Purchaser may
produce AB or CCB ATM/Debit cards with the same PIN number as the customer is
currently utilizing for their ATM/Debit card transactions prior to Closing. Both
tapes shall include file formats and/or file layouts of all ATM/Debit card
information and all related custumer information. Seller shall further provide
any and all information and assistance required by Purchaser as are reasonable
and customary in conversions of the kind contemplated by this Agreement. In
addition, from the date that the production tape is produced until the Data
Processing Conversion, Seller shall maintain, make available and deliver to
Purchaser a manual log of all new/replacement cards issued, changes to existing
cards/PIN numbers, and other such data so that Purchaser may make similar manual
changes to cards being produced for customers to be used after the date of the
Data Processing Conversion. Upon the Data Processing Conversion, Seller's Data
Processor shall deactivate the operation of the Seller's ATM/Debit cards with
respect to the Transferred Accounts. Purchaser and Seller agree to settle, on a
daily basis, the net amount of ATM debits/credits associated with transferred
accounts until the conversion date. Seller shall provide all necessary
information and reports with respect to such ATM/Debit card activity on the
Transferred Accounts so that Purchaser may appropriately debit/credit the
Transferred Accounts for such ATM/Debit card activity and balance sais activity
to the General Ledger or Settlement Accounts.

         (b)  Purchaser and Seller agree to cooperate with each other to assure
that all transactions originated through the ATM or originated with the ATM
Cards prior to or on the Closing Date shall be for the account of Seller and all
transactions originated after the Closing Date shall be for the

                                       25
<PAGE>   86
account of Purchaser. A post closing adjustment shall be made to reflect all
such transactions, which cannot be reasonably calculated as of the Closing.

                                    ARTICLE X
                             AMENDMENT; TERMINATION

         10.1 AMENDMENT. This Agreement may be amended in writing at any time
with the mutual consent of the Board of Directors of Purchaser and Seller.
Purchaser and Seller hereby covenant that neither shall unreasonably take any
action or refuse to take any action, whether or not specifically or generally
contemplated as a part of this Agreement, wherein such action or non-action
would interfere with the accomplishment of the transaction contemplated by this
Agreement.

         10.2 TERMINATION. This Agreement and the obligations created hereby
shall terminate in the event that any one or the following events occur: (i) the
necessary regulatory approvals have not been obtained prior December 1, 2000,
(ii) by the Board or Directors of Purchaser if any of the conditions provided in
ARTICLE IV herein shall not have satisfied, complied with or performed in any
material respect, and Purchaser shall not have waived such failure of
satisfaction, noncompliance or non-performance; or (iii) by the Board of
Directors of Seller if any of the conditions provided in ARTICLE V shall not
have been satisfied, complied with or performed in any material respect, and
Seller shall not have waived such failure of satisfaction, noncompliance or
non-performance; or (iv) the mutual agreement of the parties. Any material
condition contained in the approval of the transactions contemplated by this
Agreement by the FDIC, FRB, OBRE or the OTS will be subject to the consent of
the Boards of Directors of both Purchaser and Seller, as limited under the terms
of this Agreement.

         If termination of this Agreement shall be judicially determined to have
been caused by breach of this Agreement by either party, then, in addition to
other remedies at law or equity for breach of this Agreement, breaching party
shall indemnify the other party for its costs, fees and expenses of its counsel,
accountants and other experts and advisors as well as fees and expenses incident
to negotiation, preparation and execution of this Agreement in related actions.
If termination of this Agreement shall be judicially determined to have been
caused by breach of this Agreement by either party, then the breaching party
shall pay promptly, and in any event within ten (10) days of receipt of written
notice from the other party, to the other party TWO HUNDRED THOUSAND AND
NO/100THS ($200,000.00) DOLLARS plus the other party's costs, fees and expenses
of its counsel, accountants and other experts and advisors as well as fees and
expenses incident to negotiation, preparation and execution of this Agreement,
as liquidated damages.

         Except as provided in the immediately preceding paragraph, if this
Agreement is terminated, for whatever reason, then (i) this Agreement shall
forthwith become void and of no effect and without liability to any party to
this Agreement; (ii) each party hereto shall pay all of its costs incurred by it
in the negotiation, preparation and execution of this Agreement and the
obtaining of the necessary approvals thereof, including fees and expenses of

                                   ARTICLE XI
                                  MISCELLANEOUS

         11.1 A. NON-SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.
None of the representations or warranties and agreements in this Agreement or in
any instrument delivered pursuant to this Agreement shall survive the Closing
Date, except for the covenants and agreements, which by their terms are
contemplated to be performed after the Closing Date, including but not limited
to the Covenant not to Compete.

         11.1 B. CLAIMS REGARDING THE TRANSFERRED ACCOUNTS. Notwithstanding
anything herein contained to the contrary it is agreed that all insurance
coverage relating to claims arising from Seller's administration of the
Transferred Accounts prior to the Closing Date shall, to the extent assignable,
be assigned to Purchaser. To the extent such insurance claims are either a) not
transferable or b) not otherwise covered by any insurance, then Seller agrees to
indemnify, defend, and hold Purchaser harmless from any losses, judgments,
expenses, attorneys fees or costs threatened or incurred by Purchaser as a
result of such claims, provided, however, that Seller shall not indemnify,
defend or hold Purchaser harmless from Purchaser's own negligence or willful
misconduct.

         11.2 NOTICES. All notices, requests, demands and other communications
hereunder shall be in writing and may be delivered via facsimile transmission,
overnight carrier or registered or certified mail postage prepaid. When notice
is given via facsimile transmission, it shall be conclusively deemed to have
been received on the date of transmittal provided the sender receives
confirmation of transmittal to the number set forth below. Notice given by
overnight carrier shall be conclusively deemed received on the date following
the date sent. Notice sent registered or certified mail, postage prepaid, shall
be conclusively deemed to have been received three (3) business days after its
deposit in the United States mail when sent to the other party at the received
address set forth below. Either party may change the address to which notice
shall be sent by giving written notice to the other party.

         11.3 SUCCESSORS AND ASSIGNS. All terms and provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective transferees, successors and assigns, but the Agreement may not be
assigned by either party without the written consent of the other.

         11.4 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, all of which taken together shall constitute one action and the
same instrument.

         11.5 GOVERNING LAW. This Agreement is being delivered and is intended
to be performed in the State of Illinois and shall be construed and enforced in
accordance with the laws of the State of Illinois or the United States of
America, as applicable.

         11.6 REMEDIES NOT EXCLUSIVE. No remedy conferred by any of the specific
provisions of this Agreement is intended to be exclusive of any other remedy,
and each and every remedy shall be cumulative and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity or
by statute or otherwise. The election of any one or more remedies by either of
the parties shall not constitute a waiver of the right to pursue other available
remedies.

         11.7 ASSIGNMENT. This Agreement shall not be assignable by either party
without the written consent of the other. Nothing in this Agreement, expressed
or implied, is intended to confer upon any person other than the parties hereto
and their successors and permitted assigns any right or remedy under or by
reason of this Agreement.

         11.8 COSTS. All of the costs and expenses, including legal and
accounting fees attendant to this transaction, incurred by either party in
connection with this Agreement and the transactions contemplated hereby shall be

                                       28

termination caused by breach by either party.

         11.9  PARAGRAPH HEADINGS. The paragraph headings in this Agreement are
for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

         11.10 GENDER, ETC. Words herein, regardless of the number and gender
specifically used, shall be deemed and construed to include any other number,
singular or plural and any other gender, masculine, feminine or neuter, as the
context requires.

         11.11 ENTIRE AGREEMENT. This Agreement, along with the Confidentiality
Agreement, constitutes the entire agreement between Purchaser and Seller. There
are no written or oral agreements between Purchaser and Seller in connection
with this Agreement that are not set forth herein or in the exhibits attached
hereto. This Agreement supersedes and replaces any and all prior agreements
between Purchaser and Seller whether written or oral, except the Confidentiality
Agreement.

         11.12 SEVERABILITY. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction; provided, however, that in the event the
invalid provision shall result in a material change in the terms or conditions
of this Agreement, the party against whom the provision affects may terminate
this Agreement; provided that such invalid or unenforceable provision(s) cannot
be replaced with a new provision which has the most nearly similar permitable
economic effect and which is acceptable to Purchaser and Seller.

         11.13 RULE OF CONSTRUCTION. The language and all parts of this
Agreement shall in all cases be construed as a whole according to its fair
meaning, strictly neither for nor against any party hereto, and without
implication or presumption that the terms hereof shall be more strictly
construed against any party by reason of the rule of construction that a
document is to be construed more strictly against the person who prepared this
Agreement.
