Item  5.  Other Events

On July 16, 1999, South Branch Valley Bancorp, Inc. ("South Branch") and Potomac
Valley Bank ("Potomac"),  a West Virginia  chartered  banking  association which
operates  two banking  offices in  Petersburg,  West  Virginia,  entered into an
Agreement and Plan of Merger (the "Agreement").

Pursuant  to the terms of the  Agreement,  South  Branch will change its name to
Summit  Financial  Group,  Inc.  ("Summit")  and  Potomac  will be merged into a
wholly-owned  subsidiary  of Summit (the  "Merger").  Upon  consummation  of the
Merger  (subject to  adjustment,  as provided in the  Agreement),  each share of
Potomac  common  stock  will be  converted  into the  number of shares of Summit
common  stock  resulting  by dividing the book value per share of Potomac by the
book  value  per  share  of  Summit   immediately   prior  to   consummation  (a
book-for-book exchange). As of March 31, 1999, each shareholder of Potomac stock
would  have  been  entitled  to  approximately  3.22  shares  of South  Branch's
(Summit's) stock for each share of Potomac then held.

In addition, the Agreement provides, among other terms, that Patrick N. Frye
will continue to serve as President of Potomac and H. Charles Maddy, III,
will continue to serve as President of South Branch and of Summit.  G. R.
Ours, Jr. will serve as Vice Chairman and Oscar M. Bean will serve as
Chairman of Summit.

The transaction is subject to regulatory  approvals and to the approvals of both
South Branch's and Potomac's  shareholders.  This  transaction is expected to be
accounted for using the pooling of interests method of accounting.

The Agreement is attached as an exhibit hereto.
