                    DISTRIBUTED TO SHAREHOLDERS OF UNION NATIONAL

    3.01.  CONSIDERATION.  Upon and by reason of the Merger becoming effective,

shares such shareholder would have received if the recapitalization had not
occurred.

         (a)  Following the Effective Date, distribution of stock certificates
    representing First Merchants common stock and cash payments for fractional
    shares shall be made by First Merchants to each former shareholder of Union
    National within ten (10) days of such shareholder's delivery of his/her
    certificates representing common stock of Union National to the conversion
    agent, First Merchants Bank (the "Conversion Agent").  Interest shall not
    accrue or be payable with respect to any cash payments.

         (b)  Following the Effective Date, stock certificates representing
    Union National common stock shall be deemed to evidence only the right to
    receive ownership of First Merchants common stock (for all corporate

    payable subsequent to the Effective Date on stock of First Merchants shall
    be paid to any shareholder entitled to receive the same until such
    shareholder has surrendered his/her certificates for Union National common
    stock to the Conversion Agent in exchange for certificates representing
    First Merchants common stock and cash.  Upon surrender, there shall be paid
    to the recordholder of the new certificate(s) evidencing shares of First
    Merchants common stock, the amount of all dividends and other
    distributions, without interest thereon, withheld with respect to such
    common stock.

         (c)  First Merchants shall be entitled to rely upon the stock transfer
    books of Union National to establish the persons entitled to receive cash
    and shares of common stock of First Merchants, which books, in the absence
    of actual knowledge by First Merchants of any adverse claim thereto, shall
    be conclusive with respect to the ownership of such stock.

         (d)  With respect to any certificate for shares of Union National
    common stock which has been lost, stolen, or destroyed, First Merchants
    shall be authorized to issue common stock to the registered owner of such
    certificate upon receipt of an affidavit of lost stock certificate, in form
    and substance satisfactory to First Merchants, and upon compliance by the
    Union National shareholder with all procedures historically required by
    Union National in connection with lost, stolen, or destroyed certificates.

    have been met.

         (l)  The Disclosure Letter contains a list of each employment,
    severance or other similar contract, arrangement or policy and each plan or

such action as is reasonably necessary to qualify the shares of common stock of
First Merchants to be issued in connection with the Merger for quotation in the

from the parties, which representations may take the form of written
certifications.

    9.04.  AFFILIATE AGREEMENTS.  First Merchants shall have obtained (a) from

    9.06.  OFFICER'S CERTIFICATE.  First Merchants and Union National shall
have delivered to each other a certificate signed by their Chairman or President

                                      SECTION 10

                                TERMINATION OF MERGER


    10.01.  MANNER OF TERMINATION.  This Agreement and the transactions
contemplated hereby may be terminated at any time prior to the Effective Date by
written notice delivered by First Merchants to Union National or by Union
National to First Merchants:

         (a)  By Union National or First Merchants, if there has been a
    material misrepresentation, breach of warranty or failure to comply with
    any covenant on the part of any party in the representations, warranties,
    and covenants set forth herein; provided the party in default shall have no
    right to terminate for its own default;

         (b)  By Union National or First Merchants, if it shall have reasonably
    determined that the transactions contemplated by this Agreement have become
    inadvisable or impracticable by reason of commencement or threat of
    material litigation or proceedings against any of the parties;

         (c)  By Union National or First Merchants if there have been any
    changes or events of any character, actual or threatened, since September
    30, 1995, which in the aggregate materially adversely affect First
    Merchant's (on the one hand) or Union National's or the Bank's (on the
    other hand) business, prospects, condition (financial or otherwise), assets
    or results of operations (excluding events and conditions relating to the
    business environment in general and those set forth in the Disclosure
    Letter);

         (d)  By Union National or First Merchants, if the transaction
    contemplated herein has not been consummated by December 31, 1996;

    forth in any update to the Disclosure Letter has had or, in the reasonable
    discretion of First Merchants,



                                       Page 29



    may have a material adverse effect on the financial condition, results of
    operations, business, or prospects of Union National or Bank;

         (f)  By First Merchants or Union National if, in the opinion of
    counsel to First Merchants or Union National, the Merger will not
    constitute a tax-free reorganization under the Code;

         (g)  By Union National if First Merchants or any of its subsidiary
    banks is acquired by a third party in a merger, consolidation, share
    exchange, stock transaction or asset transaction; if First Merchants enters
    into an agreement containing the terms and conditions of such a
    transaction; or if the terms and conditions of such a transaction are
    publicly disclosed;

         (h)  By Union National if between the date of this Agreement and the
    Effective Date, (i) First Merchants issues, grants, sells or redeems any of
    its capital stock, or issues, grants, sells or redeems any security,
    option, warrant or other right that provides for the purchase of capital
    stock of First Merchants or that is convertible or exercisable into shares
    of the capital stock of First Merchants, or makes or sets a record date for
    a distribution of any kind to holders of the capital stock of First
    Merchants other than regular quarterly cash dividends (excluding shares of
    First Merchants capital stock and options therefor issued in connection
    with the proposed merger of Randolph County Bancorp, Inc. with and into
    First Merchants or pursuant to First Merchants Dividend Reinvestment and
    Stock Purchase Plan, Stock Option Plans or Employee Stock Purchase Plans
    (collectively, an "Equity Transaction"), or enters into an agreement,
    contract or arrangement of any kind relating to an Equity Transaction, and
    (ii) such Equity Transaction, after giving effect to the Merger, would
    decrease the projected earnings per share or book value per share
    attributable to the shares to be received by the shareholders of Union
    National in connection with the Merger;

         (i)  By First Merchants if the Merger cannot be accounted for as a
    "pooling of interests;"

         (j)  By Union National, if the appropriate discharge of the fiduciary
    duties of the Board of Directors of Union National consistent with Section
    7.05 requires that Union National terminate this Agreement; or



                                       Page 30



         (k)  By First Merchants if it receives written notice under Section
    7.05 that Union National intends to furnish information to or enter into
    discussions or negotiations with a third party in connection with a
    proposed Acquisition Transaction, if Union National fails to give any such
    written notice as required in Section 7.05 or if Union National's Board of
    Directors fails to make, withdraws or modifies its recommendation to Union
    National shareholders to vote in favor of the Merger.

    10.02.  EFFECT OF TERMINATION.  Except as set forth in this Section 10.02,
upon termination by written notice, as provided in this Section, this Agreement
shall be void and of no further force or effect and there shall be no obligation
on the part of Union National or First Merchants or their respective officers,
directors, employees, agents, or shareholders, except for payment of their
respective expenses and First Merchants obligations under Section 8.05.
Notwithstanding the foregoing, in the event of termination by First Merchants in
accordance with Section 10.01(k) or by Union National in accordance with Section
10.01(j), Union National shall pay First Merchants the sum of Five Hundred
Thousand Dollars ($500,000.00) as liquidated damages.  Such payment shall be
made within ten (10) days of the date of notice of termination.  Union National
acknowledges the reasonableness of such amount in light of the considerable time
and expense invested and to be invested by First Merchants and its
representatives in furtherance of the Merger.  Such amount was agreed upon by
First Merchants and Union National as compensation to First Merchants for its
time and expense and not as a penalty to Union National, it being impossible to
ascertain the exact value of the time and expense to be invested.  First
Merchants shall also be entitled to recover from Union National its reasonable
attorney's fees incurred in the enforcement of this Section.


                                      SECTION 11

                               EFFECTIVE DATE OF MERGER

the conditions specified in this Agreement, the Merger shall become effective at
the close of business on the day specified in the Articles of Merger of Union
National with and into First Merchants as filed with the Secretary of State of
Indiana ("Effective Date").  The Effective Date shall occur no later than the
last business day of the month in which that thirty (30) day period following
the last approval of the Merger by a federal regulatory agency or governmental
authority expires.

    this Agreement may be amended, modified, or supplemented by the written
    agreement of Union National and First Merchants without further approval of
    such shareholders, except that no such amendment, modification, or

    shareholders.
