Ohio Valley Banc Corp.

Attn.:  Mr. Jeffery E. Smith, President

The Jackson Savings Bank
221 Main Street
Jackson, OH  45640
Attn.:  Mr. Harold A. Howe, President

Gentlemen :

         Pursuant to Section 7.01(g) of the Agreement and Plan of Reorganization
dated April 8, 1998 (the "Agreement") by and between Ohio Valley Banc Corp., a
bank holding company incorporated under Ohio law ("OVB") and The Jackson Savings
Bank, a savings bank incorporated under Ohio law ("Jackson"), we hereby render
our opinion as to the federal income tax consequences of the proposed merger
("Merger") of Ohio Valley Interim Savings Bank, an interim savings bank
incorporated under Ohio law as a wholly-owned subsidiary of OVB ("Interim Bank")
solely for the purpose of carrying out the Merger with and into Jackson pursuant
to the Agreement.

                                      FACTS

         The transaction contemplated by the Agreement is a Merger under the
laws of the State of Ohio of Interim Bank with and into Jackson. OVB is a party
to the transaction by virtue of its ownership of all the common shares of
Interim Bank. Pursuant to the Agreement, each present shareholder of Jackson
will receive, in extinguishment of and in substitution for his shares of Jackson
common stock, a number of OVB common shares equal to the quotient of $163.09
divided by the average of the bid and asked prices of OVB, as reported on The
NASDAQ National Market, during the twenty (20) trading days ending five (5)
trading days before the 



   2



Closing as defined in the Agreement and carried out to four (4) decimal places
(the "Average"); provided, however, that in the event of the payment by OVB of
stock dividends, stock splits or distributions in, or combinations or
subdivisions of, OVB common shares between the date of the Agreement and the
Effective Time as defined in the Agreement, the Average shall be adjusted
appropriately. As a result of the Merger, Jackson will become a wholly-owned
subsidiary of OVB.

         No certificates or scrip representing fractional shares of OVB common
shares will be issued upon the surrender for exchange of Jackson common shares.
In lieu of any such fractional share, OVB shall pay to each former holder of
Jackson common shares who otherwise would be entitled to receive a fraction of
an OVB common share, an amount in cash equal to the product of the Average
multiplied by such fraction.

         Shareholders of Jackson whose shares are not voted in favor of the
Merger will have statutory dissenters' rights pursuant to Section 1121.09, Ohio
Revised Code, and in accordance with Section 1701.85, Ohio Revised Code, if the
Merger is consummated, and if the procedure prescribed by such law is strictly
followed, shareholders exercising such rights are entitled to receive the "fair
value" of such shares held by them.

                           ADDITIONAL REPRESENTATIONS

         You have made the following additional representations in officer's
certificates upon which we have relied:

         1. The Merger is being effected for bona fide business reasons.

         2. The fair market value of the OVB common shares to be received by the
shareholders of Jackson will be approximately equal to the fair market value of
the Jackson common shares exchanged therefor.

         3. All the common shares of Jackson outstanding immediately prior to
the Merger will be exchanged solely for common shares of OVB, except for cash
paid to dissenters or in lieu of fractional shares.

         4. To the best knowledge of Jackson, the shareholders of Jackson have
no plan or intention to sell, exchange, or otherwise dispose of a number of
shares of OVB received in the transaction to OVB or a person related to OVB that
would reduce the Jackson shareholders' ownership of OVB to a number of shares
having a value, as of the date of the transaction, of less than fifty percent
(50%) of the value of all formerly outstanding stock of Jackson as of the same
date. For purposes of this representation, any shares of Jackson common stock
surrendered by dissenters or exchanged for cash in lieu of fractional shares of
OVB will be treated as outstanding on the date of the transaction.

         5. Neither OVB nor a related person has any plan or intention to
reacquire any common shares of OVB issued in the Merger.

         6. OVB has no plan or intention to sell or otherwise dispose of any of
the assets of Jackson acquired in the Merger, except for dispositions made in
the ordinary course of business or transfers described in Section 368(a)(2)(C)
of the Internal Revenue Code of 1986, as amended (the "Code").

         7. Following the Merger, OVB or a related person will continue the
historic business of Jackson or use a significant portion of Jackson's historic
assets in a business.

         8. The liabilities of Jackson assumed by OVB in the Merger and the
liabilities to which the transferred assets of Jackson were incurred by Jackson
in the ordinary course of its business.

         9. OVB, Interim Bank, Jackson and the shareholders of Jackson will pay
their own expenses, if any, incurred in connection with the Merger.

         10. There is no intercorporate indebtedness existing between Jackson
and OVB that was issued, acquired, or will be settled at a discount.

         11. Neither OVB nor Jackson is an investment company as defined in
Section 368(a)(2)(F)(iii) and (iv) of the Code.

         12. Jackson is not under the jurisdiction of a court in a title 11 or
similar case within the meaning of Section 368(a)(3)(A) of the Code.

         13. None of the compensation received by any shareholder-employee of
Jackson will be separate consideration for, or allocable to, any of their shares
of Jackson common stock, and none of the shares of OVB common stock received by
any shareholder-employees will be separate consideration for, or allocable to,
any employment agreement.

         14. The payment of cash in lieu of fractional common shares of OVB is
solely for the purpose of avoiding the expense and the inconvenience to OVB of
issuing fractional shares and does not represent separately bargained for
consideration. The total cash that will be paid in the Merger to the
shareholders of Jackson instead of issuing fractional common shares of OVB will
not exceed one percent (1%) of the total consideration that will be issued in
the Merger to the Jackson shareholders in exchange for their Jackson common
shares. The fractional share interests of each Jackson shareholder will be
aggregated, and no shareholder will receive cash in an amount equal to or
greater than the value of one full OVB common share.

                                STATEMENT OF LAW

         Section 368(a)(1)(A) of the Code defines a tax-free reorganization to
include a statutory merger. Section 368(a)(2)(E) of the Code provides that a
transaction otherwise qualifying under paragraph (1)(A) shall not be
disqualified by reason of the fact that stock of a corporation (referred to as
the "controlling corporation"), which before the Merger was in control of the
merged corporation is used in the transaction, if (i) after the transaction, the
corporation surviving the merger holds substantially all of its properties and
of the properties of the merged corporation; and (ii) in the transaction, former
shareholders of the surviving corporation exchange, for an amount of voting
stock of the controlling corporation, an amount of stock in the surviving
corporation which constitutes control of such corporation. For this purpose, (i)
"substantially all" means at least ninety percent (90%) of the fair market value
of the assets and at least seventy percent (70%) of the fair market value of the
gross assets of the acquiring corporation; and (ii) "controlling" means the
ownership of stock possessing at least eighty percent (80%) of the total
combined voting power of all classes of stock entitled to vote and at least
eighty percent (80%) of the total number of shares of all of the classes of
stock of the corporation.

         Pursuant to the Agreement, Jackson will hold substantially all of its
properties and substantially all of the properties of Interim Bank after the
Merger. Jackson's shareholders will exchange an amount of Jackson common shares
constituting control of Jackson for OVB voting common shares.

         Certain non-statutory requirements have been imposed by the courts and
by the Internal Revenue Service in determining whether reorganizations qualify
under Section 368 of the Code. These include requirements that there be a
business purpose for the reorganization, that there be a continuity of the
business enterprise of the acquired corporation, and that the shareholders of
all corporate parties to the reorganization emerge with some continuing
proprietary interest in the entity resulting from the reorganization. Section
3.02 of Revenue Procedure 77-37, 1977-2 C.B. 568, provides that the continuity
of interest requirement is satisfied "if there is a continuing interest through
stock ownership in the acquiring or transferee corporation (or a corporation in
"control" thereof within the meaning of Section 368(c) of the Code) on the part
of the former shareholders of the acquired or transferor corporation which is
equal in value, as of the effective date, to at least fifty percent (50%) of the
value of all of the formerly outstanding stock of the acquired or transferor
corporation as of the same date."

         Pursuant to the representations that have been made, it is our opinion
that the non-statutory requirements of business purpose and continuity of
business enterprise will be satisfied. Likewise, the continuity of interest
requirement will be satisfied in that shareholders of Jackson will receive
common shares of OVB equal in value to the common shares of Jackson exchanged
therefor, which ensures that shareholders of Jackson will have a continuing
interest through stock ownership in OVB which is equal in value to at least
fifty percent (50%) of the value of all formerly outstanding Jackson common
shares as of the Effective Date.

                                     OPINION

         Therefore, based on the transaction provided for in the Agreement and
the Additional Representations, our opinion of the federal income tax
consequences of the Merger is as follows:

         1. The Merger of Interim Bank with and into Jackson will constitute a
reorganization within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of
the Code. Jackson, Interim Bank and OVB will each be a "party to the
reorganization" within the meaning of Section 368(b).

         2. No gain or loss will be recognized to Jackson upon the receipt of
the assets of Interim Bank in exchange for Jackson common shares.

         3. No gain or loss will be recognized to Interim Bank on the transfer
of its assets to Jackson in exchange solely for Jackson common shares.

         4. No gain or loss will be recognized to OVB upon the receipt of
Jackson common shares solely in exchange for Interim Bank common shares.

         5. No gain or loss will be recognized to shareholders of Jackson upon
the receipt of OVB common shares (including fractional share interests) solely
in exchange for their Jackson common shares.

         6. The basis of the OVB common shares (including fractional share
interests) to be received by Jackson shareholders will be the same as the basis
of the Jackson common shares surrendered in exchange therefor.

         7. The holding period of the OVB common shares (including fractional
share interests) to be received by Jackson shareholders will include the holding
period of the Jackson common shares surrendered in exchange therefor, provided
the Jackson common shares are held as a capital asset at the time of the
exchange.

         8. Where a cash payment is received by a Jackson shareholder in lieu of
fractional share interest of OVB, the cash payment will be treated as received
by the Jackson shareholder as a distribution in redemption of the fractional
share interest, subject to the provisions and limitations of Section 302 of the
Code.

         9. Where cash is received by a dissenting Jackson shareholder who
perfects his dissenter's rights, the cash will be treated as having been
received by the shareholder in redemption of his Jackson common shares, subject
to the provisions and limitations of Section 302 of the Code. Where, after the
receipt of such cash, a Jackson shareholder is not deemed to own any OVB common
shares under the constructive ownership rules of Section 318(a) of the Code, the
redemption will be a complete termination of such dissenting shareholder's
interest in Jackson within the meaning of Section 302(b)(3) of the Code and will
be treated as a distribution in full payment in exchange for the Jackson common
shares.

         The foregoing opinion is based on the provisions of the current
Internal Revenue Code, Treasury Regulations promulgated thereunder, and judicial
and administrative interpretations. While we believe our conclusions are
correct, no assurance can be given that the Internal Revenue Service will not,
in a subsequent audit, challenge the tax-free status of the proposed
transaction.

                                          Very truly yours,

                                          Vorys, Sater, Seymour and Pease LLP
