In the event Summit changes (or a record date for any such change occurs prior to the Effective Date) the number of, or provides for the exchange of, shares of Summit Common Stock issued and outstanding prior to the Effective Date as a result of a stock split, stock dividend, recapitalization or similar transaction with respect to the outstanding Summit Common Stock and the record date therefor shall be prior to the Effective Date, the Exchange Ratio shall be proportionately adjusted. 3.06 Provisions Relating to the Granting of Additional Options.

(v) Except as set forth by South Branch on the Disclosure Schedule, neither South Branch nor any of its Subsidiaries has any obligations to provide retiree health and life insurance or other retiree death benefits under any South Branch Compensation and Benefit Plan, other than benefits mandated by Section 4980B of the Code, and each such South Branch Compensation and Benefit Plan authorizes South Branch to amend or terminate such Plan according to its terms. There has been no communication to Employees by South Branch or any of its Subsidiaries that would reasonably be expected to promise or guarantee such Employees retiree health or life insurance or other retiree death benefits on a permanent basis.

(viii) The consummation of the transactions contemplated by this Agreement would not, directly or indirectly (including, without limitation, as a result of any termination of employment prior to or following the Effective Time) reasonably be expected to (A) entitle any Employee, Consultant or Director to any payment (including severance pay or similar compensation) or any increase in compensation, (B) result in the vesting or acceleration of any benefits under any South Branch Compensation and Benefit Plan or (C) result in any material increase in benefits payable under any South Branch Compensation and Benefit Plan. (ix) South Branch does not maintain any compensation plan, programs or arrangements, the payments under which would not reasonably be expected to be deductible as a result of the limitations under Section 162(m) of the Code and the regulations issued thereunder. (x) As a result, directly or indirectly, of the transactions contemplated by this Agreement (including, without limitation, as a result of any termination of employment prior to or following the Effective Time), none of South Branch, Potomac or the Surviving Corporation, or any of their respective Subsidiaries will be obligated to make a payment that would be characterized as an "excess parachute payment" to an individual who is a "disqualified individual" (as such terms are defined in Section 280G of the Code), without regard to whether such payment is reasonable compensation for personal services performed or to be performed in the future. 20 (m) Labor Matters.

(n) Environmental Matters. To South Branch's knowledge, neither the conduct nor operation of South Branch or its Subsidiaries nor any condition of any property presently or previously owned, leased or operated by any of them (including, without limitation, in a fiduciary or agency capacity), or on which any of them holds a Lien, violates or violated Environmental Laws and to South Branch's knowledge no condition has existed or event has occurred with respect to any of them or any such property that, with notice or the passage of time, or both, is reasonably likely to result in liability under Environmental Laws. To South Branch's knowledge, neither South Branch nor any of its Subsidiaries has received any notice from any person or entity that South Branch or its Subsidiaries or the operation or condition of any property ever owned, leased, operated, or held as collateral or in a fiduciary capacity by any of them are or were in violation of or otherwise are alleged to have liability under any Environmental Law, including, but not limited to, responsibility (or potential responsibility) for the cleanup or other remediation of any pollutants, contaminants, or hazardous or toxic wastes, substances or materials at, on, beneath, or originating from any such property.

(vi) As of the date hereof, neither South Branch nor any of its Subsidiaries has any reason to believe that any conditions exist that might prevent or impede the Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code.

All interest rate swaps, caps, floors, option agreements, futures and forward contracts and other similar risk 21 management arrangements, whether entered into for South Branch's own account or the account of its customers (all of which are listed on South Branch's Disclosure Schedule), were entered into in accordance with applicable laws, rules, regulations and regulatory policies and with counter parties believed to be financially responsible at the time; and each of them constitutes the valid and legally binding obligation of South Branch, enforceable in accordance with its terms (except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar laws of general applicability relating to or affecting creditors' rights or by general equity principles), and is in full force and effect. South Branch is not, nor to South Branch's knowledge any other party thereto, in breach of any of its obligations under any such agreement or arrangement. (q) Books and Records.

(t) Real Property. South Branch and its Subsidiaries each own the real property set forth in the Disclosure Schedule. Except as disclosed in the Disclosure Schedule, all real property owned by South Branch and its Subsidiaries is free and clear of liens and encumbrances except for liens of record, liens which do not materially affect the use of the property or liens for ad valorem taxes not yet due and payable.

The Potomac Board will recommend that the Potomac stockholders approve and adopt the Agreement and the transactions contemplated hereby, provided that the Potomac Board may fail to make such recommendation, or withdraw, modify or change any such recommendation, if the Potomac Board, after having consulted with and considered the advice of outside counsel, has determined that the making of such recommendation, or the failure to withdraw, modify or change such recommendation, would constitute a breach of the fiduciary duties of the members of the Potomac Board under applicable law. 6.03 Registration Statement.

Each of Potomac and South Branch further agrees that if it shall become aware prior to the Effective Date of any information furnished by it that would cause any of the statements in the Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other party thereof and to take the necessary steps to correct the Proxy Statement. (c) South Branch agrees to advise Potomac, promptly after South Branch receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of South Branch Stock for offering or sale in any jurisdiction, of the initiation or threat of any proceeding for any such purpose, or of any request by the SEC for the amendment or supplement of the Registration Statement or for additional information.

Subject to the requirements of law, each party will keep confidential, and will cause its representatives to keep confidential, all information and documents obtained pursuant to this Section 6.05 (as well as any other information obtained prior to the date hereof in connection with the entering into of this Agreement) unless such information (i) was already known to such party, (ii) becomes available to such party from other sources not known by such party to be bound by a confidentiality obligation, (iii) is disclosed with the prior written approval of the party to which such information pertains or (iv) is or becomes readily ascertainable from published information or trade sources.

This section shall apply only to employee benefit plans available generally to employees and shall specifically not include plans designed to compensate executive personnel of Summit and its Affiliates. 6.10 Notification of Certain Matters. Each of Potomac and South Branch shall give prompt notice to the other of any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein. 6.11 Dividend Coordination. The Potomac Board shall cause its regular semi-annual dividend record dates and payment dates for Potomac Common Stock to be the same as South Branch's regular semi-annual dividend record dates and payment dates for South Branch Common Stock (e.g., Potomac shall move its next dividend record and payment dates to the next dividend record and payment date for South Branch Common Stock), and Potomac shall not thereafter change its regular dividend payment dates and record dates (it being the intention of the parties that the stockholders of Potomac shall not receive two dividends, or fail to receive one dividend, for any single semi-annual period with respect to their shares of Potomac Common Stock or the Summit Common Stock exchanged therefor in the Merger).

During the five-year period, the maximum size of the Potomac Board of Directors shall not exceed twelve (12) persons. The requirements of this provision may be modified during the five-year period only upon the affirmative vote of three-fourths (3/4) of Summit's Board of Directors. 6.16 Location of Summit Offices. Summit's corporate offices shall be located in Moorefield, West Virginia. 6.17 Changes to Organizational Documents.

Summit shall provide and keep in force, for a period of three years after the Effective Time, directors' and officers' liability insurance providing coverage to directors and officers of 27 Potomac for acts or omissions occurring prior to the Effective Time. Such insurance shall provide at least the substantially equivalent coverage and substantially equivalent amounts as contained in any Summit policy of insurance on the date hereof; provided, that in no event shall the annual premium on such policy exceed 150% of the annual premium payments on Potomac's policy in effect as of the date hereof (the "Maximum Amount"). If the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the maximum amount, Summit shall use its reasonable efforts to maintain the most advantageous policies of directors' and officers' liability insurance obtainable for a premium equal to the Maximum Amount. Notwithstanding the foregoing, Summit further agrees to indemnify all individuals who are or have been officers, directors or employees of Potomac prior to the Effective Time from any acts or omissions in such capacities prior to the Effective Time, to the extent that such indemnification is provided pursuant to the Articles of Incorporation and Bylaws of Potomac on the date hereof as permitted under the WVCA. 6.20 Other Transactions.

Notwithstanding the foregoing, the directors of South Branch shall not be required to take any action hereunder that, upon consultation with and the advice of outside counsel, the South Branch Board has determined would constitute a breach of fiduciary duties of the members of the South Branch Board under applicable law. Nothing herein shall be construed to limit at any time the ability of South Branch or any of its Subsidiaries from entering into other agreements or transactions prior to the Effective Time pursuant to which it or its subsidiaries may merge, consolidate or affiliate with any other entity, or acquire or establish other branches or subsidiaries ("Other Transactions"). South Branch agrees to advise Potomac of such Other Transactions as and when appropriate, but in any event prior to the submission of a transaction or agreement to South Branch's Board of Directors for approval.

I have carefully read this letter and reviewed the Merger Agreement and discussed their requirements and other applicable limitations upon my ability to sell, transfer, or otherwise dispose of South Branch and Potomac Stock, to the extent I felt necessary, with my counsel or counsel for Potomac. I represent, warrant and covenant with and to Summit that in the event I receive any Summit Stock as a result of the Merger: 1.

Stock unless (i) such sale, transfer or other disposition has been registered under the Securities Act, (ii) such sale, transfer or other disposition is made in conformity with the provisions of Rule 145 under the Securities Act (as such rule may be amended from time to time), or (iii) in the opinion of counsel in form and substance reasonably satisfactory to Summit, or under a "no-action" letter obtained by me from the staff of the SEC, such sale, transfer or other disposition will not violate or is otherwise exempt from registration under the Securities Act. 2.
