To the extent that any legal or contractual restrictions 8 8 prevent the Company from paying the full amount of cash payable in accordance with the foregoing sentence, the Company shall pay to holders of the Rights as to which such payments are being made all amounts which are not then restricted on a pro rata basis. The Company shall continue to make payments on a pro rata basis as funds become available until such payments have been paid in full." 19. To amend Section 11(d) to read in its entirety as follows: "(d) In the event that, following the Share Acquisition Date, directly or indirectly: (i) the Company shall consolidate with, or merge with or into, any other Person and the Company shall not be the continuing or surviving corporation of such merger or consolidation; or (ii) any Person shall consolidate with the Company, or merge with or into the Company and the Company shall be the continuing or surviving corporation of such merger or consolidation and, in connection with such merger or consolidation, all or part of the Common Shares shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property; or (iii) the Company shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise transfer), in one or more transactions, assets or earning power (including, without limitation, securities creating any obligation on the part of the Company and/or any of its Subsidiaries) representing in the aggregate more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any Person or Persons; then, and in each such case, proper provision shall be made so that (A) each holder of a Right (except as otherwise provided herein) shall thereafter have the right to receive, upon the exercise thereof in accordance with the terms of this Agreement at an exercise price per Right equal to the product of two (2) times the then-current Purchase Price multiplied by the number of Common Shares for which a Right was exercisable immediately prior to the first occurrence of a Triggering Event, such number of validly authorized and issued, fully paid, nonassessable and freely tradeable Common Shares of the Issuer (as such term is hereinafter defined), free and clear of any liens, encumbrances and other adverse claims and not subject to any rights of call or first refusal, as shall be equal to the result obtained by (x) multiplying the product of two 9 9 (2) times the then-current Purchase Price by the number of Common Shares for which a Right is exercisable immediately prior to the first occurrence of a Triggering Event and dividing that product by (y) 50% of the current per share market price of the Common Shares of the Issuer (determined pursuant to Section 11(e) hereof), on the date of consummation of such Flip-Over Event; (B) the Issuer shall thereafter be liable for, and shall assume, by virtue of the consummation of such Flip-Over Event, all the obligations and duties of the Company pursuant to this Agreement; (C) the term "Company" shall thereafter be deemed to refer to the Issuer; and (D) the Issuer shall take such steps (including, without limitation, the reservation of a sufficient number of its Common Shares to permit the exercise of all outstanding Rights) in connection with such consummation as may be necessary to assure that the provisions hereof shall thereafter be applicable, as nearly as reasonably may be possible, in relation to its Common Shares thereafter deliverable upon the exercise of the Rights. For purposes of this Section 11(d), "Issuer" shall mean (A) in the case of any Flip-Over Event described in Sections 11(d)(i) or (ii) above, the Person that is the continuing, surviving, resulting or acquiring Person (including the Company as the continuing or surviving corporation of a transaction described in Section 11(d)(ii) above), and (B) in the case of any Flip-Over Event described in Section 11(d)(iii) above, the Person that is the party receiving the greatest portion of the assets or earning power (including, without limitation, securities creating any obligation on the part of the Company and/or any of its Subsidiaries) transferred pursuant to such transaction or transactions; provided, however, that, in any such case, (x) if (1) no class of equity security of such Person is, at the time of such merger, consolidation or transaction and has been continuously over the preceding 12-month period, registered pursuant to Section 12 of the Exchange Act, and (2) such Person is a Subsidiary, directly or indirectly, of another Person, a class of equity security of which is and has been so registered, the term "Issuer" shall mean such other Person; and (y) in case such Person is a Subsidiary, directly or indirectly, of more than one Person, a class of equity security of two or more of which are and have been so registered, the term "Issuer" shall mean whichever of such Persons is the issuer of the equity security having the greatest aggregate market value. Notwithstanding the foregoing, if the Issuer in any of the Flip-Over Events listed above is not a corporation or other legal entity having outstanding equity securities, then, and in each such case, (A) if the Issuer is directly or indirectly wholly owned by a corporation or other legal entity having outstanding equity securities, then all references to Common Shares of the Issuer shall be deemed to be 10 10 references to the Common Shares of the corporation or other legal entity having outstanding equity securities which ultimately controls the Issuer, and (B) if there is no such corporation or other legal entity having outstanding equity securities, (1) proper provision shall be made so that the Issuer shall create or otherwise make available for purposes of the exercise of the Rights in accordance with the terms of this Agreement, a kind or kinds of security or securities having a fair market value at least equal to the economic value of the Common Shares which each holder of a Right would have been entitled to receive if the Issuer had been a corporation or other legal entity having outstanding equity securities; and (2) all other provisions of this Agreement shall apply to the issuer of such securities as if such securities were Common Shares. The Company shall not consummate any Flip-Over Event unless the Issuer shall have a sufficient number of authorized Common Shares (or other securities as contemplated above) which have not been issued or reserved for issuance to permit the exercise in full of the Rights in accordance with this Section 11(d), and unless prior to such consummation the Company and the Issuer shall have executed and delivered to the Rights Agent a supplemental agreement providing for the terms set forth in Section 11(d) and further providing that as promptly as practicable after the consummation of any Flip-Over Event, the Issuer shall: (A) prepare and file a registration statement under the Securities Act, with respect to the Rights and the securities issuable upon exercise of the Rights on an appropriate form, and shall use its best efforts to cause such registration statement to (1) become effective as soon as practicable after such filing and (2) remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the earlier of the Expiration Date and the Final Expiration Date; (B) take all such action as may be appropriate under, or to ensure compliance with, the securities or "blue sky" laws of the various states in connection with the exercisability of the Rights; and (C) deliver to holders of the Rights historical financial statements for the Issuer and each of its Affiliates which comply in all respects with the requirements for registration on Form 10 (or any successor form) under the Exchange Act. The provisions of this Section 11(d) shall similarly apply to successive mergers or consolidations or sales or other transfers. In the event that a Flip-Over Event occurs at any time after the occurrence of a Flip-In Event, the 11 11 Rights which have not theretofore been exercised shall thereafter become exercisable in the manner described in this Section 11(d). In the event that the Company shall be the continuing or surviving corporation in a merger or consolidation referred to in subparagraph (ii) above and Common Shares of the Company are required to be issued upon exercise of the Rights following such merger or consolidation, and if there shall not be sufficient authorized but unissued Common Shares or authorized and issued Common Shares held in treasury to permit the exercise in full of the Rights in accordance with the foregoing, the Directors of the Company shall use their best efforts promptly to authorize and, subject to the provisions of Section 9 hereof, make available for issuance additional Common Shares; provided, however, that if at any time after 90 calendar days after the first occurrence of a Flip-In Event, there shall not be sufficient Common Shares available for issuance upon the exercise of a Right, then the Company shall deliver, upon the surrender of such Right and without requiring payment of the Purchase Price, Common Shares (to the extent available), and then cash (to the extent permitted by applicable law and any agreements or instruments to which the Company is a party in effect immediately prior to the first occurrence of any Flip-In Event), which Common Shares and cash shall have an aggregate value equal to the excess of (x) the aggregate current per share market price (determined pursuant to Section 11(e) hereof) of all the Common Shares issuable in accordance with this Section 11(d) upon the exercise of a Right over (y) the product of the then-current Purchase Price multiplied by the number of Common Shares for which a Right was exercisable immediately prior to the occurrence of the merger or consolidation referred to in subparagraph (ii) above. To the extent that any legal or contractual restrictions prevent the Company from paying the full amount of cash payable in accordance with the foregoing sentence, the Company shall pay to holders of the Rights as to which such payments are being made all amounts which are not then restricted on a pro rata basis. The Company shall continue to make payments on a pro rata basis as funds become available until such payments have been paid in full." 20.

Notwithstanding the foregoing, the Directors of the Company shall not be empowered to effect such exchange at any time after any Person (other than the Company or any Subsidiary or any employee benefit plan of the Company or of any Subsidiary or any entity holding Common Shares for or pursuant to the terms of any such plan) together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or more of the Common Shares then outstanding. Immediately upon the action of the Directors of the Company ordering the exchange of any Rights pursuant to this Section 11(p), and without any further action and without any notice, the right to exercise such Rights shall terminate and the only right with respect to such Rights thereafter of the holder of such Rights shall be to receive that number of Common Shares equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. Promptly after the action of the Directors of the Company ordering the exchange of any Rights pursuant to this Section 11(p), the Company shall publicly announce such action, and within 10 calendar days thereafter shall give notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent; provided, however, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange shall state the method by which the exchange of the Common Shares for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become void pursuant to the provisions of Section 11(a)(ii)) held by each holder of Rights. In any exchange pursuant to this Section 11(p), the Company, at its option, may substitute for any Common Share exchangeable for a Right, (i) cash, (ii) debt securities of the Company, (iii) other assets, or (iv) any combination of the foregoing, in any event having an aggregate value which the Directors of the Company shall have determined in good faith to be equal to the current per share market price of one Common Share (determined pursuant to Section 11(e) hereof) on the Trading Day 13 13 immediately preceding the date of exchange pursuant to this Section 11(p). The Company shall not be required to issue fractions of Common Shares or to distribute certificates which evidence fractional Common Shares upon the exchange of a Right. In lieu of such fractional Common Shares, the Company shall pay to the registered holders of the Right Certificates with regard to which such fractional Common Shares would otherwise be issuable an amount in cash equal to the same fraction of the current per share market price of a whole Common Share (determined pursuant to Section 11(e) hereof) on the Trading Day immediately preceding the date of exchange pursuant to this Section 11(p)." 22. To amend Section 17 to add at the end of the first sentence thereof the following: "or exchanged pursuant to the provisions of Section 11(p) hereof" 23. To amend Section 23(a) to read in its entirety as follows: "(a) Prior to the earlier of the Expiration Date and the Final Expiration Date, the Directors of the Company may, at their option, redeem all but not less than all of the then-outstanding Rights at the Redemption Price at any time prior to the Close of business on the later of (i) the Distribution Date and (ii) the Share Acquisition Date." 24. To delete Sections 23(b) and 23(f) in their entirety, and to renumber Sections 23(c), 23(d) and 23(e) as Sections 23(b), 23(c) and 23(d), respectively. 25. To delete the last two sentences of Section 23(c) (as renumbered by item 24 of this Amendment) and to add at the end of Section 23(c) the following: "; provided, however, that the failure to give, or any defect in, any such notice shall not affect the validity of the redemption of the Rights. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. The notice of redemption mailed to the holders of Rights shall state the method by which the payment of the Redemption Price will be made. The Company may, at its option, pay the Redemption Price in cash, Common Shares (based upon the current per share market price of the Common Shares (determined pursuant to Section 11(e) hereof) at the time of redemption) or any other form of consideration deemed appropriate by the Directors of the Company (based upon the fair market value of such other consideration, determined by the Directors of the Company in good faith) or any combination thereof." 14 14 26. To amend Section 23(d) (as renumbered by item 24 of this Amendment) to replace the clause "paragraphs (a) or (b) above, or both," with the following: "paragraph (a) above" 27. The form of Right Certificate attached as Exhibit A to the Rights Agreement and the form of Summary of Rights attached as Exhibit B to the Rights Agreement are hereby amended to reflect the provisions of this Amendment. 28. This Amendment is effective as of October 28, 1991, and all references to the Rights Agreement shall, as of such date, be deemed to be references to the Rights Agreement, as amended by this Amendment.
