(c) The Purchase Loan shall be without recourse to the Participant, shall be evidenced by the Participant's Purchase Note and shall bear Interest. The Purchase Note shall be in the form approved by the Committee and shall contain such terms and conditions, which are not inconsistent with the Plan, as the Committee shall determine in its sole and absolute discretion, and the Purchase Note shall be subject to the terms of the Plan even though not set forth in the Purchase Note. (d) Payment of the Purchase Note shall be secured by a pledge of all the shares of Company Stock acquired by the Participant upon the exercise of the Purchase Award to which the Purchase Loan relates. The Participant shall effect such pledge by delivering to the Company (i) the certificate or certificates for the acquired shares of Company Stock, accompanied by a duly executed stock power in blank, and (ii) a properly executed stock pledge agreement in such form as approved by the Committee. - 6 - PAGE 7 (e) Dividends paid on shares of Company Stock pledged as security for a Purchase Loan shall be first applied by the Company to pay Interest accrued and unpaid on the Participant's Purchase Note and then to repayment of the Purchase Note. (f) Within ten (10) Business Days after the maturity date of the Purchase Loan, or on the date as of which the Participant elects to prepay the Purchase Loan and Purchase Note as provided in Section 6(b), the Participant shall repay in full the then unpaid principal balance of the Purchase Note, accrued and unpaid Interest, applicable federal and state withholding taxes, and costs associated with the Purchase Loan. If not fully paid when due, Participant agrees to sell his pledged Company Stock to the Company at the Market Price on the maturity date, if a Business Day (or at the Market Price on the Business Day immediately preceding the maturity date if the maturity date is not a Business Day). The Participant agrees to sell to the Company, or the Company may sell on the open market (except as hereinafter provided), the number of shares of Company Stock pledged as collateral necessary to repay in full the Purchase Note, accrued and unpaid Interest, applicable federal and state withholding taxes, and costs associated with the Purchase Loan. If the pledged shares are sold on the open market, the Company shall receive and apply the sale proceeds (net of brokerage fees, collection fees and federal or state withholding taxes on income applicable to the transaction) realized from such sale toward repayment of the Purchase Note, accrued and unpaid Interest, applicable federal and state withholding taxes, and costs associated with the Purchase Loan. If, pursuant to procedures established by the Company for compliance with securities laws, the Company believes that the purchase of pledged shares by the Company in repayment of the Purchase Note, or the sale by the Company of pledged shares of Company Stock on the open market to repay the Purchase Note, would violate any provision of applicable securities laws or cause the Participant to incur a liability under Section 16(b) of the Exchange Act, the maturity date may be extended by the Committee until the first day the purchase by the Company of the pledged shares or a sale of the pledged shares on the open market can be made without violating such securities laws or incurring such liability under Section 16(b). Subject to the agreements of participants as provided in Sections 7(c) and (d) below, any shares of Company Stock remaining after repayment of the Purchase Note, accrued and unpaid Interest, applicable federal and state withholding taxes, and costs associated with the Purchase Loan, shall be transferred to the Participant. - 7 - PAGE 8 (g) The Purchase Price and the principal amount of a Participant's Purchase Loan and Purchase Note, plus accrued and unpaid Interest, shall be adjusted as follows if at any time after the second anniversary date of the Purchase Note (or first anniversary date if the initial term of the Purchase Note is four (4) years or less) the Market Price of Company Stock equals or exceeds the Purchase Price of the Participant's Company Stock by the amount specified below for a period of ten (10) consecutive Business Days: Interest Purchase Price/ Reduction Note Reduction Purchase Price + $5 Interest Spread 0 Purchase Price + $10 Interest Spread 5% Purchase Price + $15 Interest Spread 15% Purchase Price + $20 Interest Spread 25% The provisions of this paragraph and any applicable adjustments to Interest and the Purchase Note shall be applied at the time of repayment of the Purchase Note. Decreases in the Market Price of Company Stock subsequent to the completion of a measuring period shall be disregarded for purposes of the adjustments authorized by this paragraph. (h) In the event of a change in capital structure involving the transfer of any of the pledged shares of Company Stock, as provided in Section 9, such newly-acquired shares shall be pledged to the Company as substitute or additional security. (i) Notwithstanding anything in this Section 6 to the contrary, the Company shall not be required to make a Purchase Loan to a Participant if making such Purchase Loan will (i) cause the Company to violate any covenant or other similar provision in any indenture, loan agreement, or other agreement, or (ii) violate any applicable federal, state or local law. (j) Upon exercise of a Purchase Award, the delivery of the consideration to the Company for the exercise of the Purchase Award and issuance by the Company of Company Stock purchased pursuant to the Purchase Award, the Participant shall be deemed a shareholder of the Company and (subject to the terms of the Plan, the Purchase Loan, the Purchase Note and related documents) shall be entitled (i) to dividends on such Company Stock owned or pledged, and (ii) to exercise all voting rights with respect to the Company Stock purchased. 7. Termination of Employment; Change of Control; Prepayment of Purchase Loan If before the Purchase Note is repaid a Participant's employment terminates, a Change of Control occurs, or the Committee authorizes repayment of the Purchase Loan, the following provisions shall apply notwithstanding any terms in the Purchase Note to the contrary: - 8 - PAGE 9 (a) If the termination of employment is the result of death, Disability or Retirement, or if a Change of Control occurs, or with the consent of the Committee, the Participant (or the Participant's estate or personal representative in the event of death or incapacity) may either (i) prepay the Purchase Note, or (ii) continue to participate in the Plan until the maturity date of the Purchase Note. (b) If the termination of employment is the result of a mutual agreement between the Participant and the Company or is involuntary for reasons other than Cause, or if the Participant's employer ceases to be a Subsidiary in a divisive transaction involving a sale of shares or substantially all of the assets of the Subsidiary, the maturity date of the Purchase Note shall be accelerated without further action of the Committee or the Company to the date of termination of employment, and (i) Section 6(g) shall not apply, and (ii) the Participant agrees to sell his pledged Company Stock to the Company at the greater of (x) the Market Price on the date of termination of employment, and (y) an amount equal to his down payment paid to the Company pursuant to Section 6(a). (c) If the termination of employment is voluntary by the Participant or involuntary by the Company for Cause, the maturity date of the Purchase Note shall accelerate without further action of the Committee or the Company to the date of termination of employment, Section 6(g) shall not apply, and the Participant agrees to sell his pledged Company Stock to the Company at the lesser of (i) the down payment paid to the Company pursuant to Section 6(a), and (ii) the Market Price on the date of termination of employment, and the Company shall have the right to retain any excess Market Price. (d) A Participant may, with the consent of the Committee, prepay the Purchase Loan before the third anniversary date of the Purchase Note (or second anniversary date if the initial term of the Purchase Note is four (4) years or less). In such case Section 6(g) shall not apply and the Participant agrees to sell the pledged Company Stock to the Company for the lesser of (i) the down payment paid to the Company pursuant to Section 6(a), and (ii) the Market Price on the prepayment date fixed by the Committee, and the Company shall have the right to retain any excess Market Price. (e) If a Change of Control occurs, a Participant can elect to prepay his or her Purchase Note at any time before the maturity date and paragraph (d) shall not apply, and paragraphs (b) and (c) shall not apply to a termination of employment that occurs subsequent to a Change of Control. 8.

(b) If the Company is a party to a consolidation or a merger in which the Company is not the surviving corporation, a transaction that results in the acquisition of substantially all of the Company's outstanding stock by a single person or entity, or a sale or transfer of substantially all of the Company's assets, the Committee may take such actions with respect to outstanding unexercised Purchase Awards as the Committee deems appropriate. (c) Notwithstanding anything in the Plan to the contrary, the Committee may take the foregoing actions without the consent of any Participant, and the Committee's determination shall be conclusive and binding on all persons for all purposes. 10.
