In the event there is a significant acquisition or disposition of any assets, business division, company or other business operations of the Company that is reasonably expected to have an effect on Free Cash Flow, the Committee shall adjust the Performance Goal to take into account the impact of such acquisition or disposition by increasing or decreasing such Performance Goal in the same proportion as Free Cash Flow of the Company would have been affected for the prior calendar year on a pro forma basis had such an acquisition or disposition occurred on the same date during the prior calendar year. Such adjustment shall be based upon the historical equivalent of Free Cash Flow of the assets so acquired or disposed of for the prior calendar year, as shown by such records as are available to the Company, as further adjusted to reflect any aspects of the transaction that should be taken into account to ensure comparability between amounts in the prior calendar year and the year to which the performance condition applies.

(4) Effect of Failure of Vesting Date to Occur. An Initial Election shall be null and void if a Vesting Date does not occur with respect to Restricted Stock Units identified in such Initial Election.

-4-

(b) Subsequent Elections/Acceleration Elections. No Subsequent Election shall be effective until 12 months after the date on which a Subsequent Election is filed with the Committee.

(1) If Grantee makes an Initial Election, or pursuant to this Paragraph 5(b)(1) makes a Subsequent Election, to defer the distribution date for Shares issuable with respect to some or all of the Restricted Stock Units hereby granted, Grantee may elect to defer the distribution date for a minimum of five years and a maximum of ten additional years from the previously-elected distribution date by filing a Subsequent Election with the Committee on or before the close of business at least one year before the date on which the distribution would otherwise be made.

(2) If Grantee dies before Shares subject to an Initial Election under Paragraph 5(a) are to be delivered, the estate or beneficiary to whom the right to delivery of such Shares shall have passed may make a Subsequent Election to defer receipt of all or any portion of such Shares for five additional years from the date delivery of Shares would otherwise be made, provided that such Subsequent Election must be filed with the Committee at least one year before the date on which the distribution would otherwise be made, as reflected on Grantee’s last Election.

(3) In lieu of a Subsequent Election described in Paragraph 5(b)(2), the estate or beneficiary to whom the right to delivery of Shares shall have passed may, as soon as practicable following the Grantee’s death, make an Acceleration Election to accelerate the delivery date of such Shares from the date delivery of such Shares would otherwise be made to a date that is as soon as practicable following the Grantee’s death.

(4) If Grantee becomes a Disabled Grantee before the Shares subject to an Initial Election under Paragraph 5(a) are to be delivered, Grantee may, as soon as practicable following the date on which Grantee becomes a Disabled Grantee, elect to accelerate the distribution date of such Shares from the date payment would otherwise be made to a date that is as soon as practicable following the date the Disabled Grantee became disabled.

(5) If Grantee becomes a Retired Grantee before Shares subject to an Initial Election under Paragraph 5(a) are to be delivered, Grantee may make a Subsequent Election to defer all or any portion of such Shares for five additional years from the date delivery of Shares would otherwise be made. Such a Subsequent Election must be filed with the Committee at least one year before the date on which the distribution would otherwise be made.

(c) Diversification Election. As provided in the Plan and as described in the prospectus for the Plan, a Grantee with an Account may be eligible to make a Diversification Election on an election form supplied by the Committee for this purpose.

(d) Book Accounts. An Account shall be established for each Grantee who makes an Initial Election. Deferred Stock Units shall be credited to the Account as of the Date an Initial Election becomes effective. Each Deferred Stock Unit will represent a hypothetical Share credited to the Account in lieu of delivery of the Shares to which an Initial Election, Subsequent Election or Acceleration Election applies. If an eligible Grantee makes a Diversification Election, then to the extent an Account is deemed invested in the Income Fund, the Committee shall credit earnings with respect to such Account at the Applicable Interest Rate.

-5-

(e) Status of Deferred Amounts. Grantee’s right to delivery of Shares subject to an Initial Election, Subsequent Election or Acceleration Election, or to amounts deemed invested in the Income Fund pursuant to a Diversification Election, shall at all times represent the general obligation of the Company. Grantee shall be a general creditor of the Company with respect to this obligation, and shall not have a secured or preferred position with respect to such obligation. Nothing contained in the Plan or an Award shall be deemed to create an escrow, trust, custodial account or fiduciary relationship of any kind. Nothing contained in the Plan or an Award shall be construed to eliminate any priority or preferred position of Grantee in a bankruptcy matter with respect to claims for wages.

(f) Non-Assignability, Etc. The right of Grantee to receive Shares subject to an Election under this Paragraph 5, or to amounts deemed invested in the Income Fund pursuant to a Diversification Election, shall not be subject in any manner to attachment or other legal process for the debts of Grantee; and no right to receive Shares or cash hereunder shall be subject to anticipation, alienation, sale, transfer, assignment or encumbrance.

6. Notices. Any notice to the Company under this Agreement shall be made in care of the Committee at the Company’s main office in Philadelphia, Pennsylvania. All notices under this Agreement shall be deemed to have been given when hand-delivered or mailed, first class postage prepaid, and shall be irrevocable once given.

7. Securities Laws. The Committee may from time to time impose any conditions on the Shares issuable with respect to Restricted Stock Units as it deems necessary or advisable to ensure that the Plan satisfies the conditions of Rule 16b-3, and that Shares are issued and resold in compliance with the Securities Act of 1933, as amended.

8. Delivery of Shares; Repayment.

(a) Delivery of Shares. Except as otherwise provided in Paragraph 5, the Company shall notify Grantee that a Vesting Date with respect to Restricted Stock Units has occurred. Within ten (10) business days of a Vesting Date, the Company shall, without payment from Grantee, satisfy its obligation to deliver Shares issuable under the Plan either by (i) delivery of a physical certificate for Shares issuable under the Plan or (ii) arranging for the recording of Grantee’s ownership of Shares issuable under the Plan on a book entry recordkeeping system maintained on behalf of the Company, in either case without any legend or restrictions, except for such restrictions as may be imposed by the Committee, in its sole judgment, under Paragraph 7, provided that Shares will not be delivered to Grantee until appropriate arrangements have been made with the Employer for the withholding of any taxes which may be due with respect to such Shares. The Company may condition delivery of certificates for Shares upon the prior receipt from Grantee of any undertakings which it may determine are required to assure that the certificates are being issued in compliance with federal and state securities laws. The right to payment of any fractional Shares shall be satisfied in cash, measured by the product of the fractional amount times the Fair Market Value of a Share on the Vesting Date, as determined by the Committee.

-6-

(b) Repayment. If it is determined by the Board that gross negligence, intentional misconduct or fraud by Grantee caused or partially caused the Company to have to restate all or a portion of its financial statements, the Board, in its sole discretion, may, to the extent permitted by law and to the extent it determines in its sole judgment that it is in the best interests of the Company to do so, require repayment of Shares delivered pursuant to the vesting of the Restricted Stock Units, or to effect the cancellation of unvested Restricted Stock Units, if (i) the vesting of the Award was calculated based upon, or contingent on, the achievement of financial or operating results that were the subject of or affected by the restatement, and (ii) the extent of vesting of the Award would have been less had the financial statements been correct. In addition, to the extent that the receipt of an Award subject to repayment under this Paragraph 8(b) has been deferred pursuant to Paragraph 5 (or any other plan, program or arrangement that permits the deferral of receipt of an Award), such Award (and any earnings credited with respect thereto) shall be forfeited in lieu of repayment.

9. Award Not to Affect Employment. The Award granted hereunder shall not confer upon Grantee any right to continue in the employment of the Company or any subsidiary or affiliate of the Company.

10. Miscellaneous.

(a) The Award granted hereunder is subject to the approval of the Plan by the shareholders of the Company to the extent that such approval (i) is required pursuant to the By-Laws of the National Association of Securities Dealers, Inc., and the schedules thereto, in connection with issuers whose securities are included in the NASDAQ National Market System, or (ii) is required to satisfy the conditions of Rule 16b-3.

(b) The address for Grantee to which notice, demands and other communications to be given or delivered under or by reason of the provisions hereof shall be Grantee’s address as reflected in the Company’s personnel records.
