date within such period, then the number of shares of Union Common Stock set

     (d) Notwithstanding anything contained herein to the contrary, Prairie
shall deliver to Union by no later than 5:00 p.m. Ottawa, Illinois time on the
twentieth day after the date of this Agreement, an agreement executed by the
holders as of such date of all of the shares of Prairie Preferred Stock to a
plan or arrangement pursuant to which immediately after the Closing:  (i) the
Surviving Corporation shall have capital stock outstanding comprised of only
shares of common stock, $1.00 par value per share, which outstanding stock

Union shall have not been required to deliver any cash, securities or other
property to any current or former shareholders of Prairie other than the Merger
Consideration.  If Prairie fails to make such delivery, this Agreement shall
terminate and such termination shall have the effect as set forth in Section
13.2.

     SECTION 8.3 FULL SATISFACTION.  All rights to receive the Merger
Consideration into and for which shares of Prairie Common Stock shall have been
converted and exchanged pursuant to this Agreement shall be deemed to have been
paid and issued in full satisfaction of all rights pertaining to such converted
and exchanged shares of Prairie Common Stock.

     SECTION 8.4 TAX FREE REORGANIZATION.  The parties hereto intend for the
Merger to qualify as a nontaxable reorganization within the meaning of Section
368 and related sections of the Internal Revenue Code of 1986, as amended, and
the rules and regulations promulgated thereunder (collectively, the "Code"),
and agree to cooperate and to take such actions as may be reasonably necessary

     SECTION 9.17 TAXES.  Each of Prairie and the Prairie Subsidiaries has
filed with the appropriate governmental agencies all federal, state and local
income, franchise, excise, sales, use, real and personal property and other tax
returns and reports required to be filed by it.  Except as set forth on
Schedule 4.17 of the Prairie Book of Schedules, neither Prairie nor any Prairie

or reports or on any assessments received by it for such taxes; (b) aware of

IRS or any state tax agency for any period since January 1, 1992.  Neither
Prairie nor any Prairie Subsidiary is, to the knowledge of Prairie, a party to
any threatened action or proceeding by any governmental authority for
assessment or collection of taxes.  The reserve for taxes in the audited
financial statements of Prairie for the year ended December 31, 1994, is
adequate to cover all of the tax liabilities of Prairie and the Prairie
Subsidiaries (including, without limitation, income taxes and franchise fees)
that may become payable in future years in respect to any transactions
consummated prior to December 31, 1994.  Neither Prairie nor any Prairie
Subsidiary has and, to the best of Prairie's knowledge, will not have any
liability for taxes of any nature for or in respect of the operation of its
business or ownership of its assets from December 31, 1994, up to and including
the Effective Time, except to the extent reflected on the audited Prairie
Financial Statements for the year ended December 31, 1994, and each of the
Prairie Subsidiaries' Call Reports, or on the Subsequent Prairie Financial
Statements or otherwise reflected in the books and records of Prairie and the
Prairie Subsidiaries for the period following its then most recent of the
Subsequent Prairie Financial Statements.

     SECTION 9.18 PRAIRIE EMPLOYEE BENEFIT PLANS.  Except as set forth on
Schedule 4.18 of the Prairie Book of Schedules, neither Prairie nor any Prairie
Subsidiary has any other Prairie Employee Benefit Plans, collective bargaining
agreements, contracts or arrangements under which pensions, deferred
compensation or other retirement benefits are being paid or may become payable
respectively by Prairie or any Prairie Subsidiary.

     SECTION 9.19 COMPLIANCE WITH ERISA.  Except as set forth in Schedule 4.19
of the Prairie Book of Schedules, all employee benefit plans (as defined in
Section 3(3) of ERISA) established or maintained by Prairie or any Prairie
Subsidiary, or to which Prairie or any Prairie Subsidiary contributes, are in
compliance in all material respects with all applicable requirements of ERISA,
and are in compliance in all material respects with all applicable requirements
(including qualification and non-discrimination requirements in effect as of
the Effective Time) of the Code for obtaining the tax benefits the Code
thereupon permits with respect to such employee benefit plans.  For purposes of
this Section, non-compliance with the Code and ERISA is material if such
non-compliance would reasonably be expected to have a material adverse effect
on the financial condition, assets or business of Prairie or any of the Prairie
Subsidiaries.  No such employee benefit plan has, or as of the Effective Time
will have, any

                                     15
   19

amount of unfunded benefit liabilities (as defined in Section 4001(a)(18) of
ERISA) for which Prairie or any Prairie Subsidiary would be liable to any
Person under Title IV of ERISA if any such employee benefit plan were
terminated as of the Effective Time, which amounts would be material to Prairie
or any Prairie Subsidiary.  Such employee benefit plans are funded in
accordance with Section 412 of the Code (if applicable).  There would be no
obligations which would be material to Prairie or any of the Prairie
Subsidiaries under Title IV of ERISA relating to any such employee benefit plan
that is a multi-employer plan if any such plan were terminated or if Prairie or
any of the Prairie Subsidiaries withdrew from any such plan as of the Effective
Time.

     SECTION 9.20 COMPLIANCE WITH ENVIRONMENTAL LAWS.  Each of Prairie and the
Prairie Subsidiaries has conducted its respective business in material
compliance with all federal, state, county and municipal laws, including
statutes, regulations, rules, ordinances, orders, restrictions and
requirements, relating to underground storage tanks, petroleum products, air
pollutants, water pollutants or process waste water or otherwise relating to
the environment or toxic or hazardous substances or to the manufacture,
processing, distribution, use, recycling, generation, treatment, handling,
storage, disposal or transport of any hazardous or toxic substances or
petroleum products (including polychlorinated biphenyls, whether contained or
uncontained, and asbestos-containing materials, whether friable or not),
including, but not limited to, the Federal Solid Waste Disposal Act, the
Hazardous and Solid Waste Amendments, the Federal Clean Air Act, the Federal
Clean Water Act, the Occupational Health and Safety Act, the Federal Resource
Conservation and Recovery Act, the Toxic Substances Control Act, the Federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980
and the Superfund Amendments and Reauthorization Act of 1986, all as amended,
and regulations of the Environmental Protection Agency, the Nuclear Regulatory
Agency and any state department of natural resources or state environmental
protection agency now or at any time hereafter in effect (collectively, the
"Environmental Laws").  There are no pending or, to the knowledge of Prairie,
threatened actions or proceedings by any local municipality, sewerage district
or other governmental entity against Prairie or any Prairie Subsidiary with
respect to the Environmental Laws and, to the knowledge of Prairie, there is no
basis or grounds for any such action or proceeding.  Except as set forth on
Schedule 4.20 of the Prairie Book of Schedules, no environmental clearances or
other governmental approvals are required for the conduct of the business of
Prairie or any Prairie Subsidiary or the consummation of the transactions
contemplated hereby.  To the best knowledge and belief of management of
Prairie, neither Prairie nor any Prairie Subsidiary is the owner of any
interest in real estate on which any substances have been used, stored,
deposited, treated, recycled or disposed of, which substances if known to be
present on, at or under such property, would require clean-up, removal or some
other remedial action under any Environmental Laws.

     SECTION 9.21 BROKERAGE COMMISSIONS.  All negotiations relating to this
Agreement and the transactions contemplated herein have been and will be
carried on by Prairie directly with Union, its counsel, accountants and other
representatives in such a manner that no actions of Prairie or any Prairie
Subsidiary or any of its respective officers, agents or representatives shall
give rise to any claim against Prairie or Union or any of its respective
Affiliates for any brokerage commission, finder's fee, investment advisor's fee
or other like payment, except that Union has agreed to make payment to Hoefer &
Arnett Incorporated, Austin, Texas, for services rendered as financial advisor
to Union in connection with the transactions contemplated by this Agreement.

     SECTION 9.22 LOAN LOSS RESERVE.  The reserve for possible loan and lease
losses shown on the September 30, 1995, Call Report of each of the Prairie
Subsidiaries is adequate in all material respects under the requirements of
generally accepted accounting principles to provide for possible losses, net of
recoveries relating to loans previously charged off, on loans outstanding
(including, without limitation, accrued interest receivable) as of September
30, 1995, for such Prairie Subsidiary.  Except as set forth in Schedule 4.22,
the aggregate loan balances of each of the Prairie Subsidiaries at such date in
excess of such reserves are, to the knowledge and belief of Prairie, and based
on past loan loss experience, collectible in accordance with their terms.

     SECTION 9.23 REGULATORY FILINGS.  Each of Prairie and the Prairie
Subsidiaries has filed in a timely  manner all required filings with all proper
regulatory authorities, including, but not limited to:  (a) the Federal
Reserve; (b) the OCC; (c) the FDIC; (d) the Commissioner; and (e) the Secretary
of State of the State of Illinois.  To the best knowledge of Prairie, all such
filings were accurate and complete in all material respects as of the dates of
the filings, and no such filing has made any untrue statement of a material
fact or omitted to state a material fact necessary in order to make the
statements made, in the light of the circumstances under which they were made,
not misleading.


                                     16
   20


     SECTION 9.24 TRUST ADMINISTRATION.  Each of Prairie and the Prairie
Subsidiaries has properly administered, in all material respects, all accounts
for which it acts as fiduciary, including but not limited to accounts for which
it serves as a trustee, agent, custodian, personal representative, guardian or
investment advisor, in accordance with the terms of the governing documents and
applicable state and federal law and regulations and common law.  To Prairie's
knowledge, none of Prairie or any Prairie Subsidiary, or any director, officer
or employee of Prairie or any Prairie Subsidiary has committed any material
breach of trust with respect to any such fiduciary account, and the accounting
for each such fiduciary account is true and correct in all material respects
and accurately reflect the assets of such fiduciary account.

     SECTION 9.25 APPROVAL DELAYS.  To Prairie's knowledge, Prairie knows of no
reason why the granting of any of the regulatory approvals referred to in
Section 12.2 would be denied or unduly delayed.

     SECTION 9.26 SHAREHOLDER APPROVALS.  The record owners of 100% of
Prairie's issued and outstanding common stock have unanimously approved and
authorized this Agreement and the Merger as required by the Illinois BCA.

                                   ARTICLE 10

     SECTION 10.17 TAXES.  Each of Union and the Union Subsidiaries has filed
with the appropriate governmental agencies all federal, state and local income,
franchise, excise, sales, use, real and personal property and other tax returns
and reports required to be filed by it.  Except as set forth on Schedule 5.17
of the Union Book of Schedules, neither Union nor any Union Subsidiary is: (a)
delinquent in the payment of any taxes shown on such returns or reports or on
any assessments received by it for such taxes; (b) aware of any pending or
threatened examination for income taxes for any year by the IRS or any state
tax agency; (c) subject to any agreement extending the period for assessment or
collection of any federal or state tax; or (d) a party to any action or
proceeding nor has any claim been asserted against it by any governmental
authority for assessment or collection of taxes.  None of the tax liabilities
of Union or any Union Subsidiary has ever been audited by the IRS or any state

                                     22
   26

tax agency for any period since January 1, 1992.  Neither Union nor any Union
Subsidiary is, to the knowledge of Union, a party to any threatened action or
proceeding by any governmental authority for assessment or collection of taxes.
The reserve for taxes in the audited financial statements of Union for the
year ended December 31, 1994, is adequate to cover all of the tax liabilities
of Union and the Union Subsidiaries (including, without limitation, income
taxes and franchise fees) that may become payable in future years in respect to
any transactions consummated prior to December 31, 1994.  Neither Union nor any
Union Subsidiary has and, to the best of Union's knowledge, will not have any
liability for taxes of any nature for or in respect of the operation of its
business or ownership of its assets from December 31, 1994, up to and including
the Effective Time, except to the extent reflected on the audited Union
Financial Statements for the year ended December 31, 1994, and each of the
Union Subsidiaries' Call Reports, or on the Subsequent Union Financial
Statements or otherwise reflected in the books and records of Union and the
Union Subsidiaries for the period following its then most recent of the
Subsequent Union Financial Statements.

     SECTION 10.18 UNION EMPLOYEE BENEFIT PLANS.  Except as set forth on
Schedule 5.18 of the Union Book of Schedules, neither Union nor any Union
Subsidiary has any other Union Employee Benefit Plans, collective bargaining
agreements, contracts or arrangements under which pensions, deferred
compensation or other retirement benefits are being paid or may become payable
respectively by Union or any Union Subsidiary.

     SECTION 10.19 COMPLIANCE WITH ERISA.  Except as set forth in Schedule 5.19
of the Union Book of Schedules, all employee benefit plans (as defined in
Section 3(3) of ERISA) established or maintained by Union or any Union
Subsidiary, or to which Union or any Union Subsidiary contributes, are in
compliance in all material respects with all applicable requirements of ERISA,
and are in compliance in all material respects with all applicable requirements
(including qualification and non-discrimination requirements in effect as of
the Effective Time) of the Code for obtaining the tax benefits the Code
thereupon permits with respect to such employee benefit plans.  For purposes of
this Section, non-compliance with the Code and ERISA is material if such
non-compliance would reasonably be expected to have a material adverse effect
on the financial condition, assets or business of Union or any of the Union
Subsidiaries.  No such employee benefit plan has, or as of the Effective Time
will have, any amount of unfunded benefit liabilities (as defined in Section
4001(a)(18) of ERISA) for which Union or any Union Subsidiary would be liable
to any Person under Title IV of ERISA if any such employee benefit plan were
terminated as of the Effective Time, which amounts would be material to Union
or any Union Subsidiary.  Such employee benefit plans are funded in accordance
with Section 412 of the Code (if applicable).  There would be no obligations
which would be material to Union or any of the Union Subsidiaries under Title
IV of ERISA relating to any such employee benefit plan that is a multi-employer
plan if any such plan were terminated or if Union or any of the Union
Subsidiaries withdrew from any such plan as of the Effective Time.

     SECTION 10.20 COMPLIANCE WITH ENVIRONMENTAL LAWS.  Each of Union and the
Union Subsidiaries has conducted its respective business in material compliance
with all Environmental Laws.  There are no pending or, to the knowledge of
Union, threatened actions or proceedings by any local municipality, sewerage
district or other governmental entity against Union or any Union Subsidiary
with respect to the Environmental Laws and, to the knowledge of Union, there is
no basis or grounds for any such action or proceeding.  Except as set forth on
Schedule 5.20 of the Union Book of Schedules, no environmental clearances or
other governmental approvals are required for the conduct of the business of
Union or any Union Subsidiary or the consummation of the transactions
contemplated hereby.  To the best knowledge and belief of management of Union,
neither Union nor any Union Subsidiary is the owner of any interest in real
estate on which any substances have been used, stored, deposited, treated,
recycled or disposed of, which substances if known to be present on, at or
under such property, would require clean-up, removal or some other remedial
action under any Environmental Laws.

     SECTION 10.21 BROKERAGE COMMISSIONS.  All negotiations relating to this
Agreement and the transactions contemplated herein and therein have been and
will be carried on by Union directly with Prairie, its counsel, accountants and
other representatives in such a manner that no actions of Union or any Union
Subsidiary or any of its respective officers, agents or representatives shall
give rise to any claim against Union or Prairie or any of its respective
Affiliates for any brokerage commission, finder's fee, investment advisor's fee
or other like payment, except that Union has agreed to make payment to Hoefer &
Arnett Incorporated, Austin, Texas, for services rendered as financial advisor
to Union in connection with the transactions contemplated hereby.

     SECTION 10.22 LOAN LOSS RESERVE.  The reserve for possible loan and lease
losses shown on the September 30, 1995, Call Report of each of the Union
Subsidiaries is adequate in all material respects under the requirements


                                     23
   27

of generally accepted accounting principles to provide for possible losses, net
of recoveries relating to loans previously charged off, on loans outstanding
(including, without limitation, accrued interest receivable) as of September
30, 1995, for such Union Subsidiary.  Except as set forth in Schedule 5.22, the
aggregate loan balances of each of the Union Subsidiaries at such date in
excess of such reserves are, to the knowledge and belief of Union, and based on
past loan loss experience, collectible in accordance with their terms.

     SECTION 10.23 REGULATORY FILINGS.  Each of Union and the Union
Subsidiaries has filed in a timely  manner all required filings with all proper
regulatory authorities, including, but not limited to:  (a) the Federal
Reserve; (b) the OCC; (c) the FDIC; (d) the Commissioner; and (e) the Secretary
of State of the State of Illinois.  To the knowledge of Union, all such filings
were accurate and complete in all material respects as of the dates of the
filings, and no such filing has made any untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements
made, in the light of the circumstances under which they were made, not
misleading.

     SECTION 10.24 TRUST ADMINISTRATION.  Each of Union and the Union
Subsidiaries has properly administered, in all material respects, all accounts
for which it acts as fiduciary, including but not limited to accounts for which
it serves as a trustee, agent, custodian, personal representative, guardian or
investment advisor, in accordance with the terms of the governing documents and
applicable state and federal law and regulations and common law.  To Union's
knowledge, none of Union or any Union Subsidiary, or any director, officer or
employee of Union or any Union Subsidiary has committed any material breach of
trust with respect to any such fiduciary account, and the accounting for each
such fiduciary account is true and correct in all material respects and
accurately reflect the assets of such fiduciary account.

     SECTION 10.25 APPROVAL DELAYS.  To Union's knowledge, Union knows of no
reason why the granting of any of the regulatory approvals referred to in
Section 12.2 would be denied or unduly delayed.

     SECTION 10.26 SHARES TO BE ISSUED IN MERGER.  The shares of Union Common
and Preferred Stock which the shareholders of Prairie will be entitled to
receive pursuant to this Agreement upon consummation of the Merger are duly
authorized and will, when issued pursuant to this Agreement, be validly issued,
fully paid and nonassessable, and will not have been issued in violation of any
pre-emptive rights.

     SECTION 10.27 SHAREHOLDER APPROVALS.  The record owners of 100% of
Acquisition Corp's issued and outstanding voting stock have unanimously
approved and authorized this Agreement and the Merger as required by the
Illinois BCA.

                                   ARTICLE 11

the Prairie Subsidiaries will furnish Union or its representatives or agents,
its attorneys' responses to auditors' requests for information, and such
financial and operating data and other information reasonably requested by
Union developed by Prairie or any of the Prairie Subsidiaries, its auditors,
accountants or attorneys (provided with respect to attorneys, such disclosure
would not result in the waiver by Prairie of any claim of attorney-client
privilege), and will permit Union, its representatives or agents to discuss
such information directly with any individual or firm performing auditing or
accounting functions for Prairie or any of the Prairie Subsidiaries, and such
auditors and accountants shall be directed to furnish copies of any reports or
financial information as developed to Union or its representatives or agents.
No investigation by Union shall affect the representations and warranties made
by Prairie.

                                     24
   28

This Section shall not require the disclosure of any information the disclosure
of which to Union would be prohibited by law.

     (b) Any confidential information or trade secrets received by Prairie, its
employees or agents in the course of the examination described in Section 7.1
shall be treated confidentially, and any correspondence, memoranda, records,
copies, documents and electronic or other media of any kind containing either

                 the Prairie Banks which constitutes a non-performing loan or
                 against any part of such indebtedness any of the Prairie Banks

     SECTION 11.4 ADVICE OF CHANGES.  Between the date hereof and the Closing
Date, Prairie shall promptly advise Union in writing of any fact which, if
existing or known at the date hereof, would have been required to be set forth
or disclosed in or pursuant to this Agreement or of any fact which, if existing
or known at the date hereof, would have made any of the representations
contained herein materially untrue, provided, however, that receipt of notice
of such facts after the date of this Agreement shall have no effect on the
truth and accuracy of the representations and warranties made in this Agreement
as of the date hereof.

     SECTION 11.5 INFORMATION PROVIDED TO UNION.  Prairie agrees that none of
the information concerning Prairie or any Prairie Subsidiary which is provided
or to be provided by Prairie or any Prairie Subsidiary to Union for inclusion
or which is included in any documents to be filed with any governmental
authority in connection with the transactions contemplated by this Agreement
will, at the respective times such documents are filed, be false or misleading
with respect to any material fact, or omit to state any material fact necessary
in order to make the statements therein not misleading.  Notwithstanding the
foregoing, Prairie shall have no responsibility for the truth or accuracy of
any information with respect to Union or the Union Subsidiaries or any of their
affiliates or associates contained in any such filings.

     SECTION 11.6 PRAIRIE SUBSIDIARIES' MINORITY STOCK.  After the execution of

the shares of the capital stock of any of the Prairie Subsidiaries not
currently owned by Prairie (the "Prairie Subsidiaries' Minority Stock").
Prairie agrees to use all reasonable efforts, and to cause each of the
directors and officers of Prairie and the Prairie Subsidiaries to use all his
or her reasonable efforts, to assist Union in acquiring all of the Prairie
Subsidiaries' Minority Stock or in entering into binding agreements to acquire
the Prairie Subsidiaries' Minority Stock on or after the Closing under this
Agreement.  Union agrees not to contact any of the holders of the Prairie
Subsidiaries' Minority Stock concerning Union's offer to buy such stock, except
with the concurrence and participation of Mr. Robert Davidson.

     SECTION 11.7 TITLE TO REAL ESTATE.  Within 90 days of the date of this

of such title insurance company to issue an ALTA owner's title insurance policy
insuring the fee simple title of Union, the Surviving Corporation or one of the
Prairie Subsidiaries in such real estate in an amount to be determined, subject
only to:  (a) public utility easements; (b) private easements, covenants and
restrictions which do not,in the reasonable judgment of Union, adversely impair
Prairie's or the respective Prairie Subsidiary's ability to use, or the value
of, the property; and (c) liens of current state and local property taxes which
are not delinquent or subject to penalty.

     SECTION 11.8 ENVIRONMENTAL MATTERS.  Union may in its discretion, prior to
the Closing, retain at its own expense an independent professional consultant
to perform an environmental site assessment and render to Union a report (an
"Environmental Report") to determine if any real property in which Prairie, or
any of the Prairie Subsidiaries, holds any interest contains or gives evidence
that any violations of Environmental Laws have occurred on any such property.
Neither Union nor its independent professional consultant shall enter upon any
such real property in which Prairie or any Prairie Subsidiary holds only a
mortgagee's interest without the prior permission of Prairie and the Person in
possession thereof.  Prairie shall not withhold such permission unreasonably,
and shall use all reasonable efforts to obtain such permission for Union from
the Person in possession of any such mortgaged real property for which Union
desires its independent professional consultant to conduct a site assessment.
Union shall have no duty to act upon any information produced by such reviews
or investigations with or for the benefit of Prairie, any Prairie Subsidiary or
any other Person, but shall provide such information to Prairie as soon as
practicable after such information becomes available to Union.  Union shall be
responsible for and cause the repair of any property that is damaged by the
environmental testing described in this Section.

     SECTION 11.9 OTHER OFFERS.  None of Prairie, any Prairie Subsidiary or any
Affiliate of Prairie or any of its respective directors, officers, employees,
representatives or agents, shall, directly or indirectly, make, encourage,
facilitate, solicit, assist or initiate any inquiry or proposal, or participate
in any negotiations with, or provide any information to, any corporation,
partnership, agent, attorney, financial advisor, Person or other entity or
group (other than Union, Acquisition Corp, an Affiliate of Union or Acquisition
Corp or an officer, employee or other authorized representative of Union,
Acquisition Corp or such Affiliate) relating to any liquidation, dissolution,
recapitalization, merger or consolidation of Prairie or any Prairie Subsidiary;
sale of a significant

                                     27
   31

amount of assets of Prairie or any Prairie Subsidiary; purchase or sale of
shares of capital stock of Prairie or any Prairie Subsidiary; or any similar
transactions involving Prairie or any Prairie Subsidiary, other than the
transactions contemplated by this Agreement.  Upon execution of this Agreement,
Prairie shall immediately cease and cause to be terminated any and all such
current contacts and negotiations with respect to any such transaction.
Prairie shall immediately inform Union of any inquiry, proposal or request for
information (including the terms thereof and the Person making such inquiry)
which it may receive in respect of such a transaction.

     SECTION 11.10 DIVIDENDS.  Between the date of this Agreement and the
Effective Time, Prairie may continue to declare and pay to the holders of each
currently outstanding series or class of Prairie Preferred Stock the normal
quarterly cash dividend required by the terms of such Prairie Preferred Stock,
as set forth in the appropriate certificate of designation, and shall declare,
pay or make no other dividend or other distribution or payment in respect of,
or redemption of, shares of Prairie Common or Preferred Stock, provided,
however, that Prairie shall pay or make no such dividend or other distribution
or payment in the quarter in which the Effective Time shall occur and in which
the holders of Prairie Preferred Stock are entitled to receive regular
quarterly dividends on the Union Common and Preferred Stock received as a
result of the Merger.  It is the intent of this Section to provide that holders
of Prairie Preferred Stock who are expected to receive shares of Union Common
Stock pursuant to the Merger, will receive either payment of dividends on their
shares of Prairie Preferred Stock as permitted under this Section or the
payment of cash dividends as the holders of shares of Union Common and
Preferred Stock for the calendar quarter during which the Effective Time shall
occur, but will not receive and will not become entitled to receive for the
same period during any calendar quarter both the payment of a permitted
dividend as the holder of Prairie Preferred Stock and the payment of a cash
dividend as the holders of either Union Common or Union Preferred Stock.  If
Prairie does not declare and pay permitted dividends on its Prairie Preferred
Stock in a particular calendar quarter because of Prairie's reasonable
expectation that the Effective Time would occur in such quarter wherein the
holders of Prairie Preferred Stock would become entitled to receive cash
dividends for such calendar quarter on the shares of Union Common or Union
Preferred Stock, and the Effective Time does not in fact occur in said calendar
quarter, then, as a result thereof, Prairie shall be entitled to declare and
pay a permitted dividend on said shares of Prairie Preferred Stock for said
calendar quarter as soon as reasonably practicable.

     SECTION 11.11 ADDITIONAL UNION ACQUISITIONS.  Prairie acknowledges that
Union is currently in negotiations with respect to other possible acquisitions
and business combinations, and notwithstanding anything contained herein to the
contrary, Prairie agrees that nothing contained herein is intended to or shall
prevent Union from continuing such negotiations, commencing any other similar
negotiations or taking any such actions that may be necessary to consummate any
such other acquisitions or business combinations so long as the same do not
prevent Union from consummating the Merger.

     SECTION 11.12  ACCOUNTING AND OTHER ADJUSTMENTS.  Prairie agrees that it
shall, and shall cause any of the Prairie Subsidiaries, to:  (a) make any
accounting adjustments or entries to its books of account and other financial
records; (b) make additional contributions to any allowance for loan and lease
losses; (c) sell or transfer any investment securities held by it; (d)
charge-off any loan or lease; (e) create any new reserve account or make
additional contributions to any other existing reserve account; (f) make
changes in any accounting method; (g) accelerate, defer or accrue any
anticipated obligation, expense or income item; and (h) make any other
adjustments which would affect the financial reporting of Union, on a
consolidated basis after the Closing, in any case as Union shall request,
provided, however, that neither Prairie nor any Prairie Subsidiary shall be
obligated to take any such requested action until immediately prior to the
Closing and at such time as Prairie shall have received reasonable assurances
that all conditions precedent to Prairie's obligations under this Agreement
(except for the completion of actions to be taken at the Closing) have been
satisfied.

                                   ARTICLE 12

                               COVENANTS OF UNION

     Union hereby covenants and agrees with Prairie as follows:

     SECTION 12.1 INFORMATION, ACCESS THERETO, CONFIDENTIALITY.  (a) Prairie,
its representatives and agents shall, at all times during normal business hours
prior to the Closing Date and upon prior reasonable notice, have full and
continuing access to the facilities, operations, records and properties of
Union and the Union Subsidiaries.

                                     28
   32

Prairie, its representatives and agents may, prior to the Closing Date, make or
cause to be made such reasonable investigation of the operations, records and
properties of Union and the Union Subsidiaries and of its and their financial
and legal condition as Prairie shall deem necessary or advisable to familiarize
itself with such records, properties and other matters; provided, that such
access or investigation shall not interfere unnecessarily with the normal
operations of Union or the Union Subsidiaries.  Upon request, Union and the
Union Subsidiaries will furnish Prairie or its representatives or agents, its
attorneys' responses to auditors' requests for information, and such financial
and operating data and other information reasonably requested by Prairie
developed by Union or the Union Subsidiaries, its auditors, accountants or
attorneys (provided with respect to attorneys, such disclosure would not result
in the waiver by Union of any claim of attorney-client privilege), and will
permit Prairie, its representatives or agents to discuss such information
directly with any individual or firm performing auditing or accounting
functions for Union or the Union Subsidiaries, and such auditors and
accountants shall be directed to furnish copies of any reports or financial
information as developed to Prairie or its representatives or agents.  No
investigation by Prairie shall affect the representations and warranties made
by Union or Acquisition Corp.  This Section shall not require the disclosure of
any information the disclosure of which to Prairie would be prohibited by law.

     (b) Any confidential information or trade secrets received by Union,
Acquisition Corp or their employees or agents in the course of the examination
described in Section 6.1 shall be treated confidentially, and any
correspondence, memoranda, records, copies, documents and electronic or other
media of any kind containing either such confidential information, or trade
secrets or both shall be destroyed by Union or, at Prairie's request, returned
to Prairie in the event this Agreement is terminated as provided in Section
13.1.  Such information shall not be used by Union, Acquisition Corp or its
agents to the detriment of Prairie or any Prairie Subsidiary.

     SECTION 12.2 CONDUCT OF BUSINESS; CERTAIN COVENANTS.  From and after the
execution and delivery of this Agreement and until the Effective Time, Union
will:

     (a) conduct its business and operate only in accordance with sound banking
and business practices and in a manner consistent with past practices; and

     (b) remain in good standing and file all required reports with all
applicable regulatory authorities.

     SECTION 12.3 SUBSEQUENT UNION FINANCIAL STATEMENTS.  As soon as available
after the date hereof, Union will furnish Prairie copies of its audited and
unaudited Consolidated Balance Sheets and the related Consolidated Statements
of Income, Consolidated Statements of Changes in Stockholders' Equity and
Consolidated Statements of Cash Flow for each annual and quarterly period
subsequent to December 31, 1994, completed prior to the Effective Time, and all
other financial reports or statements submitted to regulatory authorities after
the date hereof, to the extent permitted by law (collectively, the "Subsequent
Union Financial Statements").  The Subsequent Union Financial Statements shall
be prepared on a basis consistent with past accounting practices and shall
fairly present the financial condition and results of operations for the dates
and periods presented.  The Union Financial Statements will not include any
material assets or omit to state any material liabilities, absolute or
contingent, or other facts, which inclusion or omission would render such
financial statements misleading in any material respect.

     SECTION 12.4 ADVICE OF CHANGES.  Between the date hereof and the Closing
Date, Union shall promptly advise Prairie in writing of any fact which, if
existing or known at the date hereof, would have been required to be set forth
or disclosed in or pursuant to this Agreement or of any fact which, if existing
or known at the date hereof, would have made any of the representations
contained herein materially untrue, provided, however, that receipt of notice
of such facts after the date of this Agreement shall have no effect on the
truth and accuracy of the representations and warranties made in this Agreement
as of the date hereof.

     SECTION 12.5 INFORMATION PROVIDED TO PRAIRIE.  Union agrees that none of
the information concerning Union or any Union Subsidiary which is provided or
to be provided by Union or any Union Subsidiary to Prairie or for inclusion in
any documents to be filed with any governmental authority in connection with
the transactions contemplated by this Agreement will, at the respective times
such documents are filed, be false or misleading with respect to any material
fact, or omit to state any material fact necessary in order to make the
statements therein not misleading or.  Notwithstanding the foregoing, Union
shall have no responsibility for the truth or accuracy of any information with
respect to Prairie or the Prairie Subsidiaries or any of their affiliates or
associates contained in any such filings.


                                     29
   33


     SECTION 12.6 ADDITION OF DIRECTORS AND OFFICER.  As soon as practicable
after the Effective Time, but no later than 30 days, Union shall take such
steps as may be necessary to add Messrs. Scott Sullivan and Robert Doty to the
board of directors of Union, and to appoint Mr. Robert Davidson, currently an
officer of Prairie, as an officer of Union or a Union Subsidiary.  At any time
prior to the termination of the Standstill Agreement, if while serving as a
director of Union either of Messrs. Sullivan or Doty dies or resigns as a
director, the other shall designate as soon as practicable thereafter a
successor to such deceased or resigning director, or in the absence of such
designation, Messrs. Whalen and McDonnell shall have the right exercisable as
soon as practicable to designate such successor, provided, however, that any
person naming such successor or successors shall have first consulted with the
remaining members of Union's board with respect to any such successor and that
a majority of such remaining members shall have consented to such successor,
which consent shall not be unreasonably withheld.  After the completion of such
procedures, Union agrees to take such steps as may be necessary to add such
successor to fill any vacancy on Union's board arising as a result of such
death or resignation.

     SECTION 12.7 EMPLOYEE BENEFITS.  Union agrees to make available as soon as

any of the Union Subsidiaries, the same employee benefits on substantially the
same terms and conditions that Union may make available to its own employees or
those of the Union Subsidiaries, and the employees of Prairie and the Prairie
Subsidiaries shall be given credit for prior service with Prairie or any of the
Prairie Subsidiaries for purposes of crediting periods of service for
eligibility and vesting of all such employee benefits offered by Union,
including, but not limited to health care and life insurance, pension and
retirement benefits and vacation and sick pay, except, however, that each such
employee of Prairie or any Prairie Subsidiary shall be treated for purposes of
Union's employee stock ownership plan as a new employee who has commenced
service with Union immediately after the Effective Time.

     SECTION 12.8 ENVIRONMENTAL MATTERS.  Prairie may in its discretion, prior
to the Closing, retain at its own expense an independent professional
consultant to perform an environmental site assessment and render to Prairie an
Environmental Report to determine if any real property in which Union, or any
of the Union Subsidiaries, holds any interest contains or gives evidence that
any violations of Environmental Laws have occurred on any such property.
Neither Prairie nor its independent professional consultant shall enter upon
any such real property in which Union or any Union Subsidiary holds only a
mortgagee's interest without the prior permission of Union and the Person in
possession thereof.  Union shall not withhold such permission unreasonably, and
shall use all reasonable efforts to obtain such permission for Prairie from the
Person in possession of any such mortgaged real property for which Prairie
desires its independent professional consultant to conduct a site assessment.

or investigations with or for the benefit of Union, any Union Subsidiary or any
other Person, but shall provide such information to Union as soon as
practicable after such information becomes available to Prairie.  Prairie shall
be responsible for and cause the repair of any property that is damaged by the

partnership, agent, attorney, financial advisor, Person or other entity or
group (other than Prairie, Acquisition Corp, an Affiliate of Prairie or
Acquisition Corp or an officer, employee or other authorized representative of
Prairie, Acquisition Corp or such Affiliate) relating to any liquidation,
dissolution or recapitalization of Union or any Union Subsidiary; any merger or
consolidation of Union or any Union Subsidiary where Union or such Union
Subsidiary is not the resulting entity; sale of a significant amount of assets
of Union or any Union Subsidiary; or any similar transactions involving Union
or any Union Subsidiary, other than the transactions contemplated by this
Agreement, provided, however, that nothing contained in this Section shall be
deemed to prohibit the solicitation, negotiation or consummation of any
acquisition or purchase by Union for cash or securities of any bank or thrift
holding company, bank, thrift or other insured depository institution.  Upon
execution of this Agreement, Union shall immediately cease and cause to be
terminated any and all such contacts and negotiations with respect to any such
prohibited transaction.  Union shall immediately inform Prairie of any inquiry,
proposal or request for information (including the terms thereof and the Person
making such inquiry) which it may receive in respect of any transaction
prohibited by this Section.

such purchase.

                                   ARTICLE 18

                          TERMINATION AND ABANDONMENT

     SECTION 18.1 REASONS FOR TERMINATION AND ABANDONMENT.  This Agreement may
be terminated and abandoned upon prompt written notice to the other party or
parties before the Effective Time, notwithstanding authorization and adoption
of this Agreement by the shareholders of Prairie or Acquisition Corp or both:

     (a) By mutual consent of the boards of directors of Union and Acquisition
Corp and the board of directors of Prairie;

     (b) By Union or Acquisition Corp at any time after ten months after the
date of this Agreement, or such later date as shall have been agreed to in
writing by the parties (as the same may be extended, the "Termination Date"),
if any of the conditions provided for in Articles 9 and 11 of this Agreement
have not been met and have not been waived in writing by Union, provided,
however, that if any condition set forth in Articles 9 or 11 is required to be
satisfied prior to the Termination Date, Union may terminate this Agreement if
such condition has not been satisfied within 30 days following receipt by
Prairie of notice of such failed condition;

     (c) By Union if Prairie shall have breached one or more provisions of this
Agreement in any way which has, or would reasonably be expected to have a
material adverse effect on the rights of Union under this Agreement,
considering all such breaches in the aggregate, and where such breach has not
been cured within 30 days following receipt by Prairie of notice of such
breach;

     (d) By Prairie at any time after the Termination Date if any of the
conditions provided for in Articles 10 or 11 of this Agreement have not been
met and have not been waived in writing by Prairie; provided, however,

                                     34
   38

that if any condition set forth in Articles 10 or 11 is required to be
satisfied prior to the Termination Date, Prairie may terminate this Agreement
if such condition has not been satisfied within 30 days following receipt by
Union of notice of such failed condition; and

     (e) By Prairie if either Union or Acquisition Corp shall have breached one
or more provisions of this Agreement in any way which has, or would reasonably
be expected to have a material adverse effect on the rights of Prairie under
this Agreement, considering all such breaches in the aggregate, and where such
breach has not been cured within 30 days following receipt by Union of notice
of such breach.

     SECTION 18.2 EFFECT OF TERMINATION OR ABANDONMENT.  Except as expressly
provided herein, in the  event of the termination of this Agreement and the
abandonment of the Merger pursuant to Sections 1.2, 2.9, 3.2 or 13.1, this
Agreement shall become null and void and there shall be no liability or
restrictions on the future activities on the part of any party hereto, or its
directors, officers or shareholders, except for the obligations of Prairie and
Union concerning confidentiality referred to in Section 6.1 and Section 7.1,
respectively.

     SECTION 18.3 PAYMENT TO PRAIRIE.  (a) If the Merger contemplated herein is
not consummated because Union breaches its obligations under this Agreement,
unless such breach or failure is a result of the failure by Prairie to perform
and comply in all material respects with any of its material obligations under
this Agreement which are to be performed or complied with by it prior to or on
the date required hereunder, then Union shall pay to Prairie, upon its written
demand, an amount equal to Prairie's costs and expenses incurred in connection
with this Agreement, provided, however, that such amount shall in no event be
greater than $150,000.  Such amount shall constitute liquidated damages and the
receipt thereof shall be Prairie's sole and exclusive remedy under this
Agreement for such breach by Union.

     (b) In addition to any payment due pursuant to the immediately preceding
subsection, if the Merger contemplated herein is not consummated because Union
breaches its obligations under this Agreement, unless such breach is a result
of the failure by Prairie to perform and comply in all material respects with
any of its material obligations under this Agreement which are to be performed
or complied with by it prior to or on the date required hereunder, and within
one year after the termination of this Agreement Union enters into an agreement
with any party other than Prairie providing for the acquisition of control of
Union by such other party, then Union shall pay to Prairie, upon its written
demand, the sum of $500,000.  Such sum, together with any payment which may be
due pursuant to the immediately preceding subsection, shall constitute
liquidated damages under this Agreement and the receipt thereof shall be
Prairie's sole and exclusive remedy under this Agreement for such breach by
Union or as a result of such acquisition of control of Union by a third party,
provided, further, however, that the provisions of this Section shall in no way
limit Prairie's rights against any such third party.  For purposes of this
Section, the phrase "control of Union" shall mean the acquisition by any such
third party of:  (a) legal or beneficial ownership (as defined by Rule 13d-3
promulgated under the Securities Exchange Act of 1934, as amended) of greater
than 33% of the then issued and outstanding voting stock of Union or any Union
Subsidiary through any transaction to which Union or any Affiliate of Union is
a party; (b) all or substantially all of Union's assets; or (c) all or
substantially all of the assets of any of the Union Subsidiaries.

     SECTION 18.4 PAYMENTS TO UNION.  (a) If the Merger contemplated herein is
not consummated because Prairie breaches its obligations under this Agreement,
unless such breach or failure is a result of the failure by Union or
Acquisition Corp to perform and comply in all material respects with any of
their material obligations under this Agreement which are to be performed or
complied with by them prior to or on the date required hereunder, then Prairie
shall pay to Union, upon its written demand, an amount equal to Union's costs
and expenses incurred in connection with this Agreement, provided, however,
that such amount shall in no event be greater than $150,000.  Such sum,
together with any payment which may be due pursuant to the following
subsection, shall constitute liquidated damages and the receipt thereof shall
be Union's sole and exclusive remedy under this Agreement for such breach by
Prairie.

     (b) In addition to any payment due pursuant to the immediately preceding
subsection, if the Merger contemplated herein is not consummated because
Prairie breaches its obligations under this Agreement, unless such breach is a
result of the failure by Union or Acquisition Corp to perform and comply in all
material respects with any of their material obligations under this Agreement
which are to be performed or complied with by them prior to or on the date
required hereunder, and within one year after the termination of this Agreement
Prairie enters into an agreement with any party other than Union providing for
the acquisition of control of Prairie by such other party, then Prairie shall
pay to Union, upon its written demand, the sum of $500,000.  Such sum, together
with any payment which may be due pursuant to the immediately preceding
subsection, shall constitute liquidated damages under this Agreement and the
receipt thereof shall be Union's sole and exclusive remedy under this Agreement
for such breach by Prairie or as a result of such acquisition of control of
Prairie by a third party, provided, further,

                                     35
   39

however, that the provisions of this Section shall in no way limit Union's
rights against any such third party.  For purposes of this Section, the phrase
"control of Prairie" shall mean the acquisition by any such third party of:
(a) legal or beneficial ownership (as defined by Rule 13d-3 promulgated under
the Securities Exchange Act of 1934, as amended) of greater than 33% of the
then issued and outstanding voting stock of Prairie or any Prairie Subsidiary
through any transaction to which Prairie or any Affiliate of Prairie is a
party; (b) all or substantially all of Prairie's assets; or (c) all or
substantially all of the assets of any of the Prairie Subsidiaries.

                                   ARTICLE 19

                                 MISCELLANEOUS

     SECTION 19.1 GOVERNING LAW.  All questions concerning the construction,
validity and interpretation of this Agreement, and the performance of the
obligations imposed by this Agreement shall be governed by the internal laws of
the State of Illinois applicable to contracts made and wholly to be performed
in such state without regard to conflicts of laws.

     SECTION 19.2 ASSIGNMENT.  Neither this Agreement nor any of the rights or
obligations hereunder may be assigned, in whole or in part, by any of the
parties hereto without the prior written consent of the other parties hereto
and any purported assignment in violation hereof shall be void and of no
effect.

     SECTION 19.3 AMENDMENT AND MODIFICATION.  The parties may by written
agreement signed by all parties hereto:  (a) extend the time for the
performance of any of the obligations or other acts of the parties hereto; (b)
waive any inaccuracies in the representations or warranties contained in this
Agreement or in any document delivered pursuant to this Agreement; and (c)
waive compliance with or modify, amend or supplement any of the conditions,
covenants, agreements, representations or warranties contained in this
Agreement or waive or modify performance of any of the obligations of any of
the parties hereto, which are for the benefit of the waiving party, provided,
however, that no such modification, amendment or supplement agreed to after
authorization of this Agreement by the shareholders of Prairie shall affect the
rights of such shareholders in any manner which is materially adverse to such
shareholders.  The failure of any party hereto to enforce at any time any
provision of this Agreement shall not be construed to be a waiver of such
provision, nor in any way affect the validity of this Agreement or any part
hereof or the right of any party thereafter to enforce each and every such
provision.  No waiver of any breach of this Agreement shall be held to
constitute a waiver of any other or subsequent breach.

     SECTION 19.4 NOTICES.  All notices, requests and other communications
hereunder shall be in writing (which shall include telecopier communication)
and shall be deemed to have been duly given if delivered by hand or by
overnight express delivery service, mailed with first class postage prepaid or

     A. Union, Acquisition Corp and Prairie entered into an Agreement and Plan
of Merger dated January 22, 1996 (the "Agreement").

     B. Each of the parties to the Agreement now desires to amend the Agreement

                                   AGREEMENTS

     1. All defined terms or capitalized terms used in the Agreement shall have
the same meaning in this Amendment as in the Agreement, unless said terms are
defined herein or unless the context clearly indicates to the contrary.

     2. A new Section 6.13 shall be added to Article 6 to read as follows:

         SECTION 6.13 PORTFOLIO LOSS.  (a) If at the time immediately prior to
    the Closing there exists a Portfolio Loss (as defined below), each of the
    Prairie Stockholders agrees to make, and Prairie agrees to accept, at such
    time an additional cash contribution to Prairie, without the receipt of
    additional capital stock, in an amount equal to:  (i) one-quarter of the
    Portfolio Loss if the total Portfolio Loss is less than or equal to
    $700,000; or (ii) $175,000 plus one-half of the amount of the Portfolio
    Loss in excess of $700,000 if the total Portfolio Loss is greater than

    plus (ii) the aggregate amount of any losses realized by Prairie on sales
    of investment securities from its consolidated investment portfolio
    consummated between the date of the Agreement and the time immediately

    of investment securities from its consolidated investment portfolio
    consummated between the date of this Amendment and the time immediately
    prior to the Closing in investments other than loans made in the ordinary

    be permissible investments under Union's investment policy or as otherwise
    agreed to in writing by Union.

     3. Except as expressly amended hereby, the Agreement is hereby ratified
and confirmed and shall continue in full force and effect.

     4. This Amendment may be executed in one or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute

                         AGREEMENT AND SECOND AMENDMENT


     THIS AGREEMENT AND SECOND AMENDMENT (this "Amendment") is entered into
this 23rd day of July, 1996, by and among PRAIRIE BANCORP, INC., an Illinois
corporation ("Prairie"), UNIONBANCORP, INC., a Delaware corporation ("Union"),
PRAIRIE ACQUISITION CORPORATION, an Illinois corporation and a wholly-owned
subsidiary of Union ("Acquisition Corp"), and WAYNE W. WHALEN and DENNIS J.
MCDONNELL (referred to collectively as the "Prairie Stockholders").

                                    RECITALS

     A. Union, Acquisition Corp and Prairie entered into an Agreement and Plan
of Merger dated January 22, 1996 (the "Agreement"), and each of the parties to
the Agreement and each of the Prairie Stockholders entered into an Agreement
and First Amendment dated March 8, 1996 (the "First Amendment").

     B. Each of the parties to the Agreement, and each of the Prairie
Stockholders now desires to further amend the Agreement as set forth herein,
and the Prairie Stockholders desire to undertake obligations in addition to
those of the parties to the Agreement as a further inducement to such parties
to enter into this Amendment.

     NOW, THEREFORE, the parties to this Amendment, in consideration of the
mutual covenants contained herein, hereby agree as follows:

                                   AGREEMENTS

     1. All defined terms or capitalized terms used in the Agreement shall have
the same meaning in this Amendment as in the Agreement, unless said terms are
defined herein or unless the context clearly indicates to the contrary.

     2. On the last Business Day prior to the Closing Date, Union shall cause
the securities owned by Prairie that are listed on Exhibit A attached hereto
(the "Part A Securities") to be valued by Adams Financial Software, Inc.
("Adams").  If the aggregate fair market value of the Part A Securities as
determined by Adams is less than the aggregate book value (where for purposes
of this Amendment book value is determined in accordance with generally
accepted accounting principles as in effect on the date hereof and prior to any
adjustments required by Statement of Financial Accounting Standards No. 115) of
the Part A Securities as shown on Prairie's books and records on the last
Business Day prior to the Closing Date, then the number of shares of the Union
Preferred Stock to be issued by Union at the Closing pursuant to Section 3.2 of
the Agreement to the Prairie Stockholders shall be reduced by an amount equal
to:  (a) the difference between the aggregate book value of the Part A
Securities and the aggregate fair market value of the Part A Securities as
determined by Adams; (b) multiplied by 61.2%; and (c) divided by $1,000.  The
number of shares of Union Preferred Stock to be issued at the Closing, as
reduced, is referred to as the Actual Preferred Shares.

     3. After the Closing, Union shall cause the securities owned by Prairie
that are listed on Exhibit B attached hereto (the "Part B Securities") to be
valued by Adams on a monthly basis.  If the results of any such valuation show
that there is a negative difference between the aggregate fair market value of
the Part B Securities as determined by Adams and the book value of such
securities, and if such difference is greater than the aggregate stated value
of the Actual Preferred Shares, plus accrued but unpaid dividends, after taking
into account tax effects at a combined tax rate of 38.8%, Union shall
immediately take such steps as are reasonably necessary to sell all of the Part
B Securities as soon as is reasonably practicable.  In any event, Union shall
sell all of the Part B Securities as soon as is reasonably practicable after
the fourth anniversary of the Closing (the "Final Sale Date").  If the
aggregate net proceeds from the sale of the Part B Securities (other than
Identified Securities, as defined below) are less than the aggregate book value
of such Part B Securities, then that number of Actual Preferred Shares equal
to:  (a) the difference between the aggregate book value of the Part B
Securities (other than Identified Securities) and the aggregate net proceeds
from the sale of the Part B Securities (other than Identified Securities); (b)
multiplied by 61.2%; and (c) divided by $1,000, shall be cancelled.  The number
of Actual Preferred Shares as reduced is referred to as the Net Remaining
Preferred Shares.  Except as provided in Section 2 above and Section 4 below,
neither of the Prairie Stockholders will have any liability for any losses
incurred by Union upon a sale of all or any part of the Part A or Part B
Securities.



                                      1

     4. Notwithstanding anything contained herein to the contrary, Union may at
any time after the Closing notify the Prairie Stockholders in writing that it
intends to sell specifically identified Part B Securities (a "Union Sale
Request").  If Union has not received a written objection by noon of the first
Business Day following the day upon which the Prairie Stockholders received the
Union Sale Request, Union may complete the sale of securities identified in the
Sale Request (the "Identified Securities") with no liability on the part of the
Prairie Stockholders for any loss thereon.  If, however, Union receives within
the time prescribed such written objection signed by each of the Prairie
Stockholders, or by their authorized agents previously identified to Union,
then Union shall not sell the Identified Securities and instead shall continue
to hold such securities until the Final Sale Date or such earlier sale date in
accordance with the terms of this Amendment or as otherwise mutually agreed
among Union and each of the Prairie Stockholders.  At the Final Sale Date (or
until an earlier sale of all of the Part B Securities), if the aggregate net
proceeds from the sale of all Identified Securities are less than the aggregate
book value of such Identified Securities, then that number of Net Remaining
Preferred Shares equal to:  (a) the difference between the aggregate book value
of all Identified Securities and the aggregate net proceeds from all sales of
such Identified Securities; (b) multiplied by 61.2%; and (c) divided by $1,000,
shall be cancelled.  Prairie Stockholders severally and individually agree to
pay to Union in cash upon demand and after the sale of all of the Part B
Securities the amount of any negative difference between the aggregate stated
value of the Net Remaining Preferred Shares, plus accrued but unpaid dividends,
and the after tax loss determined by the difference between the aggregate book
value of all Identified Securities to which the sale thereof any Prairie
Stockholder has objected and the aggregate net proceeds from all sales of such
Identified Securities.

     5. In addition to the foregoing, at any time after the Closing the Prairie
Stockholders acting in unison may request Union to sell all, but not less than
all, the Part B Securities, provided that after taking into account the
expected after tax loss to be incurred by Union as a result of such sale and
the aggregate stated value, plus accrued but unpaid dividends, of the shares of
Union Preferred Stock held by the Prairie Stockholders, the Prairie
Stockholders have established a cash escrow account in an amount reasonably
satisfactory to Union to cover any after tax loss recognized upon such sale
that would not be fully offset by the cancellation of shares of Union Preferred
Stock held by the Prairie Stockholders.  Upon the receipt by Union of such
request by the Prairie Stockholders and the establishment of such escrow
account, if necessary, Union shall sell the Part B Securities as soon as is
reasonably practicable.  The amount of any such after tax loss not covered by
the cancellation of shares of Union Preferred Stock (plus accrued but unpaid
dividends) held by the Prairie Stockholders shall be paid to Union from such
escrow account, and the remaining balance of such escrow account, if any, shall
be paid to the Prairie Stockholders.

     6. Section 13.4(a) of the Agreement shall be deleted in its entirety and
replaced with the following:

         (a)  Provided that Union is ready, willing and able to consummate the
    Merger on or before August 7, 1996, if the Merger contemplated herein is
    not consummated because of the refusal to act by any of Prairie or one of
    the Prairie Stockholders, unless such refusal is a result of the failure by
    Union or Acquisition Corp to perform and comply in all material respects
    with any of their material obligations under the Agreement or this
    Amendment which are to be performed or complied with by them prior to or on
    the date required thereunder or hereunder, then Prairie shall pay to Union,
    upon its written demand, an amount equal to $500,000.  Such sum, together
    with any payment which may be due pursuant to Section 13.4(b), shall
    constitute liquidated damages and the receipt thereof shall be Union's sole
    and exclusive remedy for such breach by Prairie.

     7. The Prairie Stockholders shall have no right to redeem the Union
Preferred Stock for cash and shall have no right to convert any of the Union
Preferred Stock into shares of Union Common Stock until the Final Sale Date (or
until an earlier sale of all of the Part B Securities) and after any reductions
required by this Amendment in the number of outstanding shares of Union
Preferred Stock.

     8. All notices, requests and other communications hereunder shall be in
writing (which shall include telecopier communication) and shall be deemed to
have been duly given if delivered by hand or by overnight express delivery
service, mailed with first class postage prepaid or telecopied if confirmed
immediately thereafter by also mailing a copy of any notice, request or other
communication by mail with first class postage prepaid:

     9. To the extent that the terms of this Amendment are contrary to any
terms or provisions of the Agreement or the First Amendment, the terms of this
Amendment shall supersede any such contrary terms or provisions.  The terms and
provisions of this Amendment shall survive the Closing.

     10. Except as expressly amended hereby, the Agreement and the First
Amendment is hereby ratified and confirmed and shall continue in full force and
effect.

     11. This Amendment may be executed in one or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.
