      Re:    Merger of Randolph County Bancorp with and into First Merchants
             Corporation

Ladies and Gentlemen:

      We have acted as special counsel to First Merchants Corporation, an
Indiana corporation registered as a bank holding company under the Bank Holding
Company Act of 1956 ("First Merchants"), in connection with the proposed merger
of Randolph County Bancorp, an Indiana corporation registered as a bank holding
company under the Bank Holding Company Act of 1956 ("Randolph County"), with and
into First Merchants, pursuant to the terms of the Agreement of Reorganization
and Merger between First Merchants and Randolph County, dated January 17, 1996
("Merger Agreement"), as described in the Registration Statement on Form S-4 to
be filed by First Merchants with the Securities and Exchange Commission on
or about April 8, 1996 ("Registration Statement").

      This opinion is being rendered as required by Section 9 of the Merger
Agreement. All capitalized terms herein, unless otherwise specified, have the
meaning assigned to them in the Registration Statement.

      In connection with this opinion, we have relied on and have examined, and
we are familiar with originals or copies of, certified or otherwise identified
to our satisfaction, the (i) Merger Agreement, the (ii) Registration Statement,
and (iii) such other documents as we have deemed necessary or appropriate in
order to enable us to render the opinions below. In our examination, we have
assumed the genuineness of all signatures, the legal capacity of all natural
persons, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as certified,
conformed or photostatic copies and the authenticity of the originals of such
copies. This opinion is subject to the receipt by us prior to the effective time
of the Merger of certain written representations and covenants of  Randolph
County and First Merchants, the accuracy and truthfulness of which we shall
assume and rely upon without investigation.

      In rendering our opinion, we have considered the applicable provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), Treasury
Regulations, pertinent judicial authorities, interpretive rulings of the
Internal Revenue Service and such other authorities as we have considered
relevant.

      Based upon and subject to the foregoing, provided that the merger of
Randolph County with and into First Merchants qualifies as a statutory merger
under applicable state law, and assuming that (i) after the transaction, First

                                       Ex. 8-1

Merchants, as successor of Randolph County, will hold substantially all of its
assets, and that (ii) in the transaction, the Randolph County shareholders will
exchange an amount of stock constituting majority control of Randolph County
solely for First Merchants common stock, we are of the opinion that the Merger
will, under current law, constitute a reorganization within the meaning of
Section 368(a)(1)(A) of the Code and that Randolph County and First Merchants
will each be a party to the reorganization within the meaning of Section 368(b)
of the Code. As a reorganization under Section 368(a)(1)(A) of the Code, the
Merger will have the following federal income tax consequences for Randolph
County shareholders, Randolph County, and First Merchants:

             1.    No gain or loss will be recognized by Randolph County
      shareholders who exchange all of their Randolph County common stock for
      First Merchants common stock pursuant to the Merger, except to the extent
      of gain or loss attributable to any cash received in lieu of receipt of a
      fractional share of First Merchants common stock.

             2.    The basis of First Merchants common stock (including deemed
      fractional share interests) received by Randolph County shareholders who
      exchange all of their Randolph County common stock for First Merchants
      common stock will be the same as the basis of the Randolph County common
      stock surrendered in exchange therefor.

             3.    The holding period of the First Merchants common stock
      received by the Randolph County shareholders (including deemed fractional
      share interests) who exchange all of their Randolph County common stock
      for First Merchants common stock will include the period during which the
      Randolph County common stock was held, provided the Randolph County
      common stock was held as a capital asset on the date of the exchange.

             4.    Where a cash payment is received by a Randolph County
      shareholder in lieu of fractional shares of First Merchants common stock,
      the cash payment will be treated as a distribution in redemption of the
      deemed fractional share interest by First Merchants, subject to the
      provisions and limitations of Section 302 of the Code. Where such
      exchange qualifies under Section 302(a) of the Code, such shareholder
      will recognize a capital gain or loss provided that the Randolph County
      common stock was held as a capital asset on the date of the Merger.

             5.    Any Randolph County shareholder who perfects dissenter's
      rights and receives solely cash in exchange for such shareholder's
      Randolph County common stock shall be treated as having received such
      cash as a distribution in redemption of the Randolph County common stock
      subject to the provisions and limitations of Section 302 of the Code. If,
      as a result of such distribution, such Randolph County shareholder owns
      no First Merchants common stock, either directly or through the
      application of the constructive ownership rules of Section 318(a) of the
      Code, the redemption will be a complete termination of interest within
      the meaning of Section 302(b)(3) of the Code and the cash will be treated
      as a distribution in full payment and exchange for the Randolph County
      common stock as provided in Section 302(a) of the Code. Under Section
      1001 of the

      Code, gain or loss (subject to any applicable limitations of the Code)
      will be realized and recognized by such Randolph County shareholder in an
      amount equal to the difference between the redemption price and the
      adjusted basis of the Randolph County common stock surrendered in
      exchange therefor.

             6.    No gain or loss will be recognized by Randolph County or
      First Merchants in connection with the transaction.

             7.    The basis of the assets of Randolph County acquired by First
      Merchants in the Merger will be the same as the basis of such assets in
      the hands of Randolph County immediately prior to the Merger.

application of existing federal income tax law to the facts as presented to us,
and we give no assurance that changes in such law or any interpretation thereof
will not affect the opinions expressed by us. Moreover, there can be no

obligation to advise of any changes concerning the above, whether or not deemed
material, which may hereafter come or be brought to our attention.

      Except as set forth above, we express no opinion as to the tax
consequences to any party, whether federal, state, local or foreign, of the
Merger or of any transactions related to the Merger or contemplated by the
Merger Agreement. This opinion is addressed to you and is being furnished to you

                                  Very truly yours,
