          (d)   The Prospectus, any exhibits, schedules or attachments thereto,
     or any written statement furnished to prospective investors by Ohio State
     Bancshares, Inc. in connection with the Offering, does not or will not

     material fact necessary to  make any statement therein not misleading.
     There is no fact which Ohio State Bancshares, Inc. has not disclosed to
     Community Banc or any prospective investor in writing which materially
     affects adversely nor, so far as Ohio State Bancshares, Inc. can now
     foresee, will materially affect adversely the business, prospects,
     properties, profits, or condition (financial or otherwise) of Ohio State
     Bancshares, Inc.

     2.   REPRESENTATION AND WARRANTIES OF COMMUNITY BANC.

     Community Banc hereby represents and warrants to Ohio State Bancshares,

     Ohio, which is the only state in which Community Banc will offer and sell
     the Common Stock on behalf of Ohio State Bancshares, Inc., in the Offering,
     and Community Banc shall remain duly licensed in such state throughout the
     term of the offer and sale of the Common Stock and shall comply with all
     statutes and other requirements applicable to it as a licensed securities
     dealer,

          (b)    Community Banc will act in its capacity as underwriter of the 
     Common Stock only in accordance with the terms and conditions set forth
     herein and in the Prospectus; and

          (c)    Community Banc has full corporate power and authority to sign
     this Agreement and to undertake underwriting of the Offering as

     4.   COVENANT OF OHIO STATE BANCSHARES.

     If any event shall have occurred as a result of which the Prospectus 
     (including any exhibits, schedules or attachments thereto) or any other
     written materials previously furnished to prospective investors would
     include any untrue statement of a material fact, or omit to state a
     material fact necessary in order to make the statements therein nor
     misleading, Ohio State Bancshares, Inc. shall notify Community Banc and,
     upon Community Banc's request, shall prepare and furnish Community Banc
     with a supplement or amendment to the Prospectus or other written
     materials, as applicable, which will correct such statement or omission as
     Community Banc may from time to time reasonably request.

     5.   INDEMNIFICATION.

          (a)    Ohio State Bancshares, Inc. shall indemnify and hold harmless 
     Community Banc, and each of its controlling persons within the meaning of
     the Act, against any and all losses, claims, damages, liabilities, costs
     and expenses (including attorneys' and experts' fees) to which Community
     Banc or any such controlling person may become subject, insofar as such
     losses, claims, damages, liabilities, costs and expenses (including
     attorneys' and experts' fees), or actions in respect thereof, arise out of
     or are based upon any actions, in connection with the Offering and sale of
     the Common Stock by Ohio State Bancshares, Inc. or its agents (other than
     by Community Banc, its employees or affiliates), employees or affiliates,
     which are alleged to be in violation of the Act, or any other applicable
     federal or state securities law or regulation or the terms and conditions
     of the Offering set forth in the Prospectus.

          (b)    Community Banc shall indemnify and hold harmless Ohio State 
     Bancshares, Inc. and each of its controlling persons within the meaning of
     the Act, against any and all losses, claims, damages, liabilities, costs
     and expenses (including attorneys' and experts' fees) to which Ohio State
     Bancshares, Inc. or any such controlling person may become subject, insofar
     as such losses, claims, damages, liabilities, costs and expenses (including
     attorneys' and experts' fees), or actions in respect thereof, arise out of
     or are based upon the activities of Community Banc as underwriter in the
     offering of the Common Stock, which are alleged to be in violation of the
     Act or any other applicable federal or state securities law or regulation,
     or the terms and conditions of the Offering set forth in the Prospectus.

          (c)    Promptly after receipt by an indemnified party under this 
     Section 5 of notice of the commencement of any action, such indemnified
     party shall, if a claim in respect thereof is to be made against any
     indemnifying party under the Section 5, notify the indemnifying party of
     the commencement thereof; but the



   4

     omission to so notify the indemnifying party shall not relieve it from any
     liability under the Section 5.  In the event any such action is brought
     against any indemnified party, and it notifies and indemnifying party of
     the commencement thereof, the indemnifying party shall be entitled to
     participate therein and, to the extent that it may wish, jointly with any
     other indemnifying party similarly notified, assume the defense thereof,
     with counsel who shall be to the reasonable satisfaction of such
     indemnified party, and after notice from the indemnifying party to such
     indemnified party of its election so to assume the defense thereof, the
     indemnifying party shall not be liable to such indemnified party under this
     Section 5 for any legal or other expenses subsequently incurred by such
     indemnified party in connection with the defense thereof other than
     reasonable costs of investigation.

     6.   REPRESENTATIONS AND INDEMNITIES TO SURVIVE THE OFFERING.

          The respective indemnities, agreements, representations, warranties, 
     covenants and other statements of Ohio State Bancshares, Inc. and Community
     Banc set forth in or made pursuant to this Agreement shall remain in full
     force and effect, regardless of any investigation made by or on behalf of
     Ohio State Bancshares, Inc. or Community Banc, or any controlling person of
     either, and shall survive the consummation of the Offering.

     7.   SUCCESSORS.

          This Agreement shall be binding upon and inure solely to the benefit
     of Ohio State Bancshares, Inc. and Community Banc and to the extent
     provided in Section 5, any person who controls Ohio State Bancshares, Inc.
     or Community Banc, or their respective successors and assigns, and no
     other person shall acquire or have any right under or by virtue of the
     Agreement. No investor of any of the shares of the Common Stock shall be
     constructed a successor or assign by reason merely of such purchase.

     8.   APPLICABLE LAW.

          This Agreement shall be construed and enforced in accordance with the
     laws of the State of Ohio and, to the extent that it may involve any United
     States statute, with the laws of the United States.
