WHEREAS, the parties hereto desire to amend the Agreement in certain respects in accordance with Section 11.03 of the Agreement; NOW, THEREFORE, in consideration of the mutual agreements herein contained and intending to be legally bound hereby, the parties hereto agree as follows: 1. Definitions. Capitalized terms used herein and not otherwise defined herein shall have the meaning provided therefor in the Agreement. 2. Amendments to Agreement. The Agreement is hereby amended as set forth in this Section 2: (i) Section 1.01 of the Agreement is amended to add the following new paragraphs (c) and (d): (c) Pursuant to an offer to purchase, dated May 4, 1995 (the "Offer to Purchase"), Merger Subsidiary has offered to purchase all of the outstanding Shares at a price of $18.10 per Share, net to the seller in cash (the "Offer"). On or prior to the close of business on May 23, 1995, Buyer shall cause Merger Subsidiary to amend and supplement the Offer to Purchase to (i) increase the price being offered pursuant to the Offer from $18.10 to $22.00 per Share (the "New Offer Price"), net to the seller in cash, subject to any amounts required to be withheld under applicable federal, state, local, or foreign income tax regulations, and (ii) extend the expiration date of the Offer to the date which is ten (10) business days subsequent to the date that such amendment and supplement to the Offer to Purchase is first filed with the SEC (the "Expiration Date"); provided, however, that if the Minimum Condition has not been satisfied by the Expiration Date, Buyer and Merger Subsidiary agree to extend the Expiration Date for one or more periods for up to an aggregate of 30 calendar days until the Minimum Condition is satisfied. The Offer as amended pursuant to the provisions hereof is herein referred to as the "Amended Offer" and unless the context otherwise requires, all references in the Agreement to the "Offer" shall mean the "Amended Offer" and all references in the Agreement to the "Offer Price" shall mean the "New Offer Price". (d) On the date the Offer is amended, Buyer and Merger Subsidiary shall file (i) with the SEC an amendment to the Tender Offer Statement on Schedule 14D-1 filed on May 4, 1995 (such Schedule 14D-1 together with all other amendments and supplements thereto, the "Schedule 14D- 1"), which shall include as exhibits a supplement to the Offer to Purchase (the "Supplement") and a revised letter of transmittal which provides for the Amended Offer; and (ii) with the Attorney General of the State of New York, an Amendment with respect to the Registration Statement filed on May 4, 1995 in accordance with the Security Takeover Disclosure Act. Buyer and the Company each agrees promptly to correct any information provided by it for use in the Offer Documents if and to the extent that it shall have become false or misleading in any material respect. Buyer agrees to take all steps necessary to cause the Offer Documents as so corrected to be filed with the SEC and with the Attorney General of the State of New York and to be disseminated to holders of the Shares, in each case as and to the extent required by applicable federal and state laws. The Company and its counsel shall be given a reasonable opportunity to review and comment on the amended Offer Documents, including the Supplement, prior to their being filed with the applicable authorities. (ii) Section 1.02 of the Agreement is amended to add the following new paragraphs (d) and (e): (d) The Company hereby consents to the Amended Offer and represents that its Board of Directors at a meeting duly called and held on May 21, 1995, (i) has determined that the Amended Offer is fair to, and in the best interests of, the stockholders of the Company; (ii) has approved this Amendment No. 1 and the Amended Offer; and (iii) has resolved to recommend approval and adoption of this Amendment No. 1 and acceptance of the Amended Offer by the Company's stockholders; provided that such recommendation may be withdrawn, modified or amended if, in the opinion of the Board of Directors, after consultation with independent legal counsel, such recommendation would be inconsistent with its fiduciary duties to the Company's stockholders under applicable law. The Supplement may contain reference to the recommendation of the Board of Directors that the Company's stockholders accept the Amended Offer. The Company shall promptly file with the SEC and mail to the holders of Shares an amendment to the Solicitation/Recommendation Statement on Schedule 14D-9 previously filed on behalf of the Company with the SEC (the "Schedule 14D-9 Amendment"), which amendment shall reflect such recommendation of the Board of Directors. (e) The Company agrees promptly to correct any information in the Schedule 14D-9 Amendment which shall have become false or misleading in any material respect and take all steps necessary to cause the Schedule 14D-9 Amendment as so corrected to be filed with the SEC and disseminated to holders of Shares, as and to the extent required by applicable law. Buyer and its counsel shall be given a reasonable opportunity to review and comment on the Schedule 14D-9 Amendment prior to its being filed with the applicable authorities. (iii) Section 2.05(a), clause (i) of the Agreement is hereby amended to read in its entirety as follows: (i) the excess, if any, of the Merger Consideration over the applicable exercise price of such Option by (iv) Section 11.04 of the Agreement is hereby amended to add the following new paragraph (c) at the end of Section 11.04: (c) The Company agrees to pay Buyer in respect of Buyer's expenses and lost opportunity costs an amount in immediately available funds equal to $16,000,000 promptly, but in no event later than two business days, after the occurrence of the events specified below in both clauses (A) and (B): (A) A Trigger Event within the meaning of and as specified in Section 11.04(b) of this Agreement shall have occurred at any time from or after the date hereof and, as a result thereof, this Agreement is terminated, and (B) within six months after such termination of this Agreement has occurred, an Acquisition Transaction shall have been consummated with any Person (as defined in Sections 3(a)(9) and 13(d)(3) of the Exchange Act) other than Buyer or a subsidiary or other Affiliate (as defined in Rule 12b-2 under the Exchange Act) of Buyer. For purposes of this Section, "Acquisition Transaction" shall mean (i) a merger or consolidation, or any similar business combination transaction, involving the Company; (ii) a purchase, lease or acquisition of all or substantially all of the assets of the Company and its subsidiaries taken as a whole; or (iii) the purchase or acquisition by any Person of securities representing more than 50% of the then outstanding Shares. 4.
