(a) Merger Consideration . (i) Each share of Common Stock, par value $1.00 per share, of the Company (a “ Share ” and, collectively, the “ Shares ”) issued and outstanding immediately prior to the Effective Time (other than (i) Shares owned by Parent or any direct or indirect Subsidiary (as defined in Section 5.1(a)) of Parent and (ii) any Shares owned by the Company or any direct or indirect Subsidiary of the Company except, in the case of clauses (i) and (ii), for any such Shares held on behalf of third parties (each, an “ Excluded Share ” and collectively, “ Excluded Shares ”)) (each such Share not constituting an Excluded Share, an “ Outstanding Share ” and, collectively, the “ Outstanding Shares ”) shall be converted into, and become exchangeable for, 0.77942 (the “ Exchange Ratio ”) common shares (the ” Per Share Merger Consideration ”), par value $1.00 per share, of Parent (“ Parent Common Stock ”).

(b) Exchange Procedures . Appropriate transmittal materials, to be reasonably agreed upon by Parent and the Company, shall be provided as soon as practicable after the Effective Time by the Exchange Agent to holders of record of Outstanding Shares converted in the Merger, advising such holders of the effectiveness of the Merger and the procedure for surrendering the Certificates to the Exchange Agent. Upon the surrender of a Certificate (or affidavit of loss in lieu thereof) to the Exchange Agent in accordance with the terms of such transmittal materials, the holder of such Certificate shall be entitled to receive in exchange therefor (1) a certificate representing that number of whole shares of Parent Common Stock that such holder is entitled to receive pursuant to this Article IV, (2) a check in the amount (after giving effect to any

-4-

required tax withholdings) of (A) any cash payable pursuant to Section 4.2(e) in lieu of fractional shares plus (B) any unpaid non-stock dividends and any other dividends or other distributions that such holder has the right to receive pursuant to Section 4.2(c), and, in each case, the Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the Certificates. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, a certificate representing the proper number of shares of Parent Common Stock, together with a check for any cash to be paid upon due surrender of the Certificate and any other dividends or distributions in respect thereof, may be issued and/or paid to such a transferee if the Certificate formerly representing such Shares is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid or are not applicable. If any certificate for shares of Parent Common Stock is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of such exchange that the Person (as defined below) requesting such exchange shall pay any transfer or other taxes required by reason of the issuance of certificates for shares of Parent Common Stock in a name other than that of the registered holder of the Certificate surrendered, or shall establish to the satisfaction of Parent or the Exchange Agent that such tax has been paid or is not applicable.

For the purposes of this Agreement, the term “ Person ” shall mean any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity (as defined in Section 5.1(d)(i)) or other entity of any kind or nature.

No dividends or other distributions in respect of the Parent Common Stock shall be paid to any holder of any unsurrendered Certificate until such Certificate is surrendered for exchange in accordance with this Article IV. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be issued and/or paid to the holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (A) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of Parent Common Stock and not paid and (B) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of Parent Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender.

(ii) Holders of unsurrendered Certificates shall be entitled to vote after the Effective Time at any meeting of Parent stockholders the number of whole shares of Parent Common Stock represented by such Certificates, regardless of whether such holders have exchanged their Certificates.

(d) Transfers . After the Effective Time, there shall be no transfers on the stock transfer books of the Company of the Outstanding Shares.

(e) No Fractional Shares . Notwithstanding any other provision of this Agreement, no fractional shares of Parent Common Stock will be issued and any holder of Shares entitled to receive a fractional share of Parent Common Stock but for this Section 4.2(e) shall be entitled to receive a cash payment in lieu thereof, which payment shall be calculated by the Exchange Agent and shall represent such holder’s proportionate interest in a share of Parent Common Stock based on the average of the per share closing prices of Parent Common Stock as reported on the New York Stock Exchange, Inc. (the “ NYSE ”) composite transactions reporting system for the 20 trading days ending on the fifth trading day prior to the Closing Date.

(f) Termination of Exchange Fund . Any portion of the Exchange Fund (including the proceeds of any investments thereof and any shares of Parent Common Stock) that remains unclaimed by the shareholders of the Company for 180 days after the Effective Time shall be delivered to Parent. Any shareholders of the Company who have not theretofore complied with this Article IV shall thereafter look only to Parent for delivery of any cash or any shares of Parent Common Stock and payment of any cash, dividends and other distributions in respect thereof payable or deliverable pursuant to Section 4.1, Section 4.2(c) and Section 4.2(e) upon due surrender of their Certificates (or affidavits of loss in lieu thereof), in each case, without any interest thereon. Notwithstanding the foregoing, none of Parent, the Surviving Corporation, the Exchange Agent or any other Person shall be liable to any former holder of Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws (as defined in Section 5.1(i)(i)).

(g) Lost, Stolen or Destroyed Certificates . In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond in customary amount and upon such terms as may be required by Parent as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the cash or the shares of Parent Common Stock and any cash, unpaid dividends or other distributions in respect thereof that would be payable or deliverable pursuant to this Agreement had such lost, stolen or destroyed Certificate been surrendered.

(h) Uncertificated Shares . In the case of any shares of Company Common Stock that are not represented by certificates, the Exchange Agent shall issue at the Effective Time Parent Common Stock to the holders of such shares without any action by such holders, and the parties shall make appropriate adjustments to this Section 4.2 to assure the equivalent treatment thereof.

At or prior to the Effective Time, the Company shall adopt appropriate amendments to the Company Stock Plans and such Compensation and Benefits Plans, if applicable, and the Board of Directors of the Company shall adopt appropriate resolutions, if applicable, to effectuate the provisions of this Section 4.5(b).

(c) If registration of any interests in the Company Stock Plans or other Compensation and Benefit Plans or the shares of Parent Common Stock issuable thereunder is required under the Securities Act of 1933, as amended (the “ Securities Act ”), Parent shall file with the Securities and Exchange Commission (the “ SEC ”) prior to the Effective Time a registration statement on Form S-3 or Form S-8, as the case may be (or any successor form), or another appropriate form with respect to such interests or Parent Common Stock, and shall use its reasonable best efforts to have such registration statement declared effective by the SEC as of the Effective Time and to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses contained therein and comply with any applicable state securities or “blue sky” laws) for so long as the relevant Company Stock Plans or other Compensation and Benefit Plans, as applicable, remain in effect and such registration of interests therein or the shares of Parent Common Stock issuable thereunder (and compliance with any such state laws) continues to be required.
