Notwithstanding any terms of this Agreement to the contrary, Harsco shall have the right to cause Acquisition Sub to be the Surviving Corporation of the Merger, so long as the exercise of such right does not have a material adverse effect on the interests of the holders of the Company's Common Stock in a manner which has not been disclosed to them in the Proxy Statement (as defined herein at Section 3.09) or cause a material delay in, or otherwise adversely affect, consummation of the transaction described herein; if such right is exercised, this Agreement shall be deemed to be modified to accord such change, including, without limitation, that the laws of the Commonwealth of Pennsylvania, together with the OGCL, will govern the Merger. ARTICLE II CONVERSION OF SHARES 2.01 Conversion of Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof: (a) Capital Stock of Acquisition Sub. All of the issued and outstanding shares of the common stock, par value $.01 per share, of Acquisition Sub ("Acquisition Sub Common Stock") issued and outstanding immediately prior to the Effective Time shall remain outstanding and unchanged after the Merger and shall thereafter constitute all of the issued and outstanding shares of the capital stock of the Surviving Corporation ("Surviving Corporation Common Stock"). 45 7 (b) Cancellation of Treasury Stock. All shares of common stock, without par value, of the Company ("Company Common Stock") that are owned by the Company as treasury stock shall be canceled and retired and shall cease to exist and no stock of Harsco or other consideration shall be delivered in exchange therefor. (c) Exchange Ratio for Company Common Stock. Each issued and outstanding share of Company Common Stock (other than shares to be canceled in accordance with Section 2.01(b) and other than Dissenting Shares (as defined in Section 2.01(d))) shall be converted into the right to receive $23.00 in cash (the "Merger Price"). All such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares shall cease to have any rights with respect thereto, except the right to receive the Merger Price per share, upon the surrender of such certificate in accordance with Section 2.02, without interest. (d) Dissenting Shares. (i) To the extent applicable, each outstanding share of Company Common Stock the holder of which has not voted in favor of the Merger, has perfected such holder's right to an appraisal of such holder's shares in accordance with the applicable provisions of the OGCL and has not effectively withdrawn or lost such right to appraisal (a "Dissenting Share"), shall not be converted into or represent a right to receive the Merger Price pursuant to Section 2.01(c), but the holder thereof shall be entitled only to such rights as are granted by the applicable provisions of the OGCL; provided, however, that any Dissenting Share held by a person at the Effective Time who shall, after the Effective Time, withdraw the demand for appraisal or lose the right of appraisal, in either case pursuant to the OGCL, shall be deemed to be converted into, as of the Effective Time, the right to receive the Merger Price pursuant to Section 2.01(c). (ii) The Company shall give Harsco (x) prompt notice of any written demands for appraisal, withdrawals of demands for appraisal and any other instruments served pursuant to the applicable provisions of the OGCL relating to the appraisal process received by the Company and (y) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the OGCL. The Company will not voluntarily make any payment with respect to any demands for appraisal and will not, except with the prior written consent of Harsco, settle or offer to settle any such demands. 2.02 Exchange of Certificates. (a) Exchange Agent. At the Closing or immediately prior to the Effective Time, Harsco shall make available to the Surviving Corporation for deposit with The Fifth Third Bank of Northwestern Ohio, N.A., by Harsco (the "Exchange Agent"), a cash amount equal to the aggregate Merger Price to which holders of shares of Company Common Stock shall be entitled upon consummation of the Merger, to be held for the benefit of and distributed to such holders in accordance with this Section. The Exchange Agent shall agree to hold such funds (such funds, together with earnings thereon, being referred to herein as the "Exchange Fund") for delivery as contemplated by this Section and upon such additional terms as may be agreed upon by the Exchange Agent, the Company and Harsco. (b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Surviving Corporation shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the "Certificates") whose shares are converted pursuant to Section 2.01(c) into the right to receive the Merger Price (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as the Surviving Corporation may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Price. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal duly executed and completed in accordance with its terms, the holder of such Certificate shall be entitled to receive in exchange therefor a check representing the Merger Price per share of Company Common Stock represented thereby which such holder has the right to receive pursuant to the provisions of this Article II, 46 8 and the Certificate so surrendered shall forthwith be canceled. In no event shall the holder of any Certificate be entitled to receive interest on any funds to be received in the Merger. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, the Merger Price may be issued to a transferee if the Certificate representing such Company Common Stock is presented to the Exchange Agent accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.02(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Price per share of Company Common Stock represented thereby as contemplated by this Article II. (c) No Further Ownership Rights in Company Common Stock. All cash paid upon the surrender of shares of Company Common Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock. From and after the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Section. (d) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the shareholders of the Company twenty-four (24) months after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any shareholders of the Company who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation (subject to abandoned property, escheat and other similar laws) as general creditors for payment of their claim for the Merger Price per share. Neither Harsco nor the Surviving Corporation shall be liable to any holder of shares of Company Common Stock for cash representing the Merger Price delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.
