ARTICLE 2 Eligibility 2.1 Each Director shall be eligible to participate in the Plan on the first day of the calendar quarter following election as a Director. ARTICLE 3 Benefits 3.1 The Employer shall create and maintain on its books an Account for each Director to which it shall credit amounts contributed to the Plan pursuant to this Article 3. The Employer shall also credit each Director's Account with deemed earnings for each Plan Year in accordance with the provisions of Article 8 hereof. -2- 3.2 At least 30 days prior to the commencement of any calendar quarter in a Plan Year, a Director may elect to have the Employer credit to the Director's Account an amount equal to any whole percentage or dollar amount (or shares of stock of the Employer ("Shares") to the extent that the Base Retainer would otherwise be paid in Shares) of the Director's Base Retainer, if any, to be earned for the balance of such Plan Year. If an election is made to have a contribution credited to the Director's Account for a Plan Year, the credit shall be made at the time that such amount would otherwise have been paid (or Shares distributed) and shall reduce the Director's Base Retainer with respect to that Plan Year by a corresponding amount. The Committee may establish minimum or maximum amounts that may be deferred under this Section and may change such standards from time to time.

Any election by a Director pursuant to this Section 3.3 shall be irrevocable and may not be modified in any respect. ARTICLE 4 Distributions to Directors 4.1 A Director's benefit under the Plan shall be distributed in one lump sum (including Shares to the extent the Director elected to defer the receipt of such Shares pursuant to Section 3.2), or, if the value of the Director's Account is at least $25,000, in 12 annual installments (with the balance to be distributed, including Shares, if applicable, continuing to be credited with deemed earnings for each subsequent Plan Year in accordance with the provisions of Article 8 hereof) equal to 1\12, 1\11, 1\10\, 1\9, 1\8, 1\7, 1\6, 1\5, 1\4, 1\3, 1\2, and 1\1 of the balance then credited to the Director's Account, and shall be paid, or commence, as soon as practicable following the completion of the valuation of the Director's Account for the last day of the month in which the Director has a Termination from Service; provided however, that each Director shall make an election, in the form and manner specified by the Committee, as to the form of payment on or before the end of the year preceding the year of payment. If no such election has been made by the first day of the year in which the Director has a Termination from Service then distribution shall be delayed and shall be made, or commence, as soon as practicable after the first day of the year following the year in which the Director has a Termination from Service. Notwithstanding anything herein to the contrary, in the event that such a Director fails to make an election, distribution shall be in the form of one lump sum payment, including Shares, paid as soon as practicable after the first day of the year following the date the Director has a Termination from Service. -3- 4.2 In the event that a Director incurs a "significant financial hardship" while a Director, as determined by the Committee, the Director may apply, in writing, for a withdrawal of all or a portion of the balance credited to the Director's Account (including Shares, if elected by the Director) in the form of a lump sum. All determinations by the Committee regarding the existence of a financial hardship shall be made in accordance with the provisions of the Company's Thrift Plan dealing with whether a financial hardship exists for purposes of permitting withdrawals thereunder.

The benefit payment to the Beneficiary will be made as soon as practicable following the completion of the valuation of the deceased Director's Account. In the event of the death of a Director after payment of a benefit has commenced in installments, pursuant to Section 4.1 hereof, the Director's Beneficiary shall receive the payments due following the Director's death; provided, however, that prior to receiving the next annual installment, the Beneficiary may elect to receive, on the next payment date, in full satisfaction of the Beneficiary's entitlement under the Plan, a lump sum distribution (including any Shares then credited to the Director's Account) equal to the remaining balance then credited to the Director's Account. ARTICLE 6 Vesting 6.1 The balance credited to a Director's Account attributable to Section 3.2 shall be fully vested at all times. -4- ARTICLE 7 Funding 7.1 The Board may, but shall not be required to, authorize the establishment of a trust by the Employer to serve as the funding vehicle for the benefits described in Article 3 hereof. In any event, the Employer's obligation hereunder shall constitute a general, unsecured obligation, payable solely out of its general assets, and no Director shall have any right to any specific assets of the Employer. In addition, it is the intention of the Employer that the Plan be unfunded for tax purposes and for purposes of Title I of the Employee Retirement Income Security Act of 1974, as amended. ARTICLE 8 Investments 8.1 The balance credited to a Director's Account (other than Shares) shall be deemed to be invested in an interest bearing instrument which shall provide for interest to be credited and compounded monthly at an effective rate equal to 50 basis points in excess of the prime commercial lending rate established by Mellon Bank N.A., or such other bank determined by the Committee to be the Company's primary bank as of the beginning of any Plan Year, as in effect on the 15th day of each month (or if such day is a non-business day, on the first business day thereafter) during which there is a positive balance in a Director's Account. Interest shall be applied to the average balance of each Director's Account during the prior 30-day period. For any Plan Year, the Committee may determine to make available, and announce to the Directors the procedure to elect, other deemed forms of investment for the amounts credited to the Accounts. A Director's Account, to the extent credited with any Shares, shall be deemed to earn any dividends paid with respect to such Shares and the accumulated dividends, as and when sufficient in amount, shall be deemed invested in additional whole Shares. ARTICLE 9 Administration 9.1 The Committee shall have full power and authority to interpret the Plan, to prescribe, amend and rescind any rules, forms and procedures as it deems necessary or appropriate for the proper administration of the Plan and to make any other determinations and to take any other such actions as it deems necessary or advisable in carrying out its duties under the Plan. All action taken by the Committee arising out of, or in connection with, the administration of the Plan or any rules adopted thereunder, shall, in each case, lie within its sole discretion, and shall be final, conclusive and binding upon the Employer, the Board, all Employees, all beneficiaries of Employees and all persons and entities having an interest therein. -5- 9.2 Members of the Committee shall serve without compensation for their services unless otherwise determined by the Board.

ARTICLE 10 Amendment 10.1 The Plan may be amended by the Committee at any time and from time to time all without prior notice to any person or entity; provided, however, that no such amendment shall have the effect of divesting a Director of the benefit which the Director would otherwise receive hereunder at the time the amendment is adopted. ARTICLE 11 Termination 11.1 Continuance of the Plan is completely voluntary and is not assumed as a contractual obligation of the Employer. The Committee, acting on behalf of the Employer, shall have the right to terminate the Plan in whole or in part at any time all without prior notice to any person or entity; provided, however, that such termination shall not have the effect of divesting a Director of the benefit which the Director would otherwise receive hereunder at the time of the termination. -6- ARTICLE 12 Miscellaneous 12.1 Nothing contained herein shall be construed as conferring upon a Director the right to continue in such capacity. 12.2 The rights and obligations created hereunder shall be binding on a Director's heirs, executors and administrators and on the successors and assigns of the Employer. 12.3 The provisions of the Plan shall be construed and applied under the laws of the Commonwealth of Pennsylvania. 12.4 The rights of any Director under this Plan are personal and may not be assigned, transferred, pledged or encumbered. Any attempt to do so shall be void. In addition, a Director's rights hereunder are not subject, in any manner, to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment by creditors of the Director or the Director's Beneficiary. 12.5 If any provision of the Plan shall be held invalid or unenforceable, such invalidity or unenforceability shall not effect any other provisions hereof and the Plan shall be construed and enforced as if such provisions had not been included. 12.6 The headings and captions herein are provided for convenience only, and shall not be construed as part of the Plan, and shall not be employed in the construction of the Plan. 12.7 Any benefit payable to or for the benefit of a payee who is a minor, an incompetent person, or is otherwise incapable of receipting therefore shall be deemed paid when paid to such person's guardian or to the party providing, or a reasonably appearing to provide, the care for such person, and such payment shall fully discharge the Employer, the Committee, the Board and all other parties with respect thereto.
