The Merger Agreement is more fully described in Section 11 of the Offer to Purchase. THE BOARD OF DIRECTORS OF THE COMPANY UNANIMOUSLY (1) DETERMINED THAT THE OFFER, THE MERGER AND THE MERGER AGREEMENT ARE ADVISABLE, FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY'S STOCKHOLDERS, (2) APPROVED THE MERGER, THE OFFER, THE MERGER AGREEMENT AND THE OTHER TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT AND (3) RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT THERETO AND APPROVE AND ADOPT THE MERGER AGREEMENT. For purposes of the Offer, Purchaser shall be deemed to have accepted for payment, and thereby purchased, Shares validly tendered and not properly withdrawn when, as and if Purchaser gives oral or written notice to the Depositary of its acceptance for payment of such Shares. Payment for Shares so accepted will be made by deposit of the purchase price therefor with the Depositary, which will act as agent for tendering stockholders for the purpose of receiving payment from Purchaser and transmitting payment to validly tendering stockholders. In all cases, payment for Shares accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of (i) certificates representing such Shares (or timely confirmation of a book-entry transfer of such Shares into the Depositary's account at The Depository Trust Company ("DTC")), (ii) a properly completed and duly executed Letter of Transmittal (or facsimile thereof ) with any required signature guarantees or an Agent's Message (as defined in the Offer to Purchase) in connection with a book-entry transfer and (iii) any other documents required by the Letter of Transmittal. The term "Expiration Date" means 12:00 midnight, New York City time, on Monday, April 24, 2000, unless and until Purchaser (subject to the terms and conditions of the Merger Agreement) extends the period of time for which the Offer is open, in which event the term "Expiration Date" shall mean the latest time and date at which the Offer, as so extended by Purchaser, shall expire prior to the purchase of any Shares. Purchaser may, without the consent of the Company, extend the Offer beyond the initial Expiration Date in the following events: (i) if necessary to satisfy any condition of the HSR Act, for a period not to exceed forty (40) business days, (ii) if any of the conditions to the Offer (other than the Minimum Condition) shall not have been satisfied or waived, for a period not to exceed twenty (20) business days, (iii) if all the conditions to the Offer are satisfied or waived, but the number of Shares validly tendered and not withdrawn is less than 90% of the number of then-outstanding Shares on a fully diluted basis (excluding Shares held by the Company or any of its subsidiaries), for four successive five (5) business day periods for an aggregate period not to exceed twenty (20) business days, or (iv) if any of the conditions to the Offer (other than the Minimum Condition) shall not have been satisfied or waived and a proposal or offer for a merger or certain other extraordinary transactions (a "Takeover Proposal") has been made or publicly disclosed by a person other than Parent or Purchaser (including the Company and any of its subsidiaries or affiliates), or if Parent or Purchaser otherwise learn that a Takeover Proposal has been made or publicly proposed, for a period of up to ten (10) days after the withdrawal or termination of such Takeover Proposal, such date in no event to exceed the earlier of (x) June 30, 2000, and (y) the minimum time necessary to satisfy all such outstanding conditions to the Offer. Purchaser shall cause any such extension by giving oral or written notice of such extension to the Depositary, which will be followed by public announcement thereof no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date. During any such extension, all Shares previously tendered and not properly withdrawn will remain subject to the Offer, subject to the right, if any, of a tendering stockholder to withdraw such stockholder's Shares. Under no circumstances will interest be paid on the purchase price to be paid for the Shares pursuant to the Offer, regardless of any extension of the Offer or any delay in making such payment. Tenders of Shares made pursuant to the Offer are irrevocable, except that Shares tendered pursuant to the Offer may be withdrawn at any time prior to the Expiration Date and, unless theretofore accepted for payment pursuant to the Offer, also may be withdrawn at any time after Monday, May 22, 2000. For a withdrawal of Shares tendered to be effective, a written or facsimile transmission notice of withdrawal must be timely received by the Depositary at one of its addresses set forth in the Offer to Purchase. Any notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name(s) in which the certificate(s) representing such Shares are registered, if different from that of the person who tendered such Shares. If certificates for Shares to be withdrawn have been delivered or otherwise identified to the Depositary, the name of the registered holder and the serial numbers shown on the particular certificate evidencing the Shares to be withdrawn must also be furnished to the Depositary prior to the physical release of the Shares to be withdrawn. The signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution (as defined in the Offer to Purchase) (except in the case of Shares tendered by an Eligible Institution). If Shares have been tendered pursuant to the procedures for book-entry transfer, any notice of withdrawal must specify the name and number of the account at DTC to be credited with such withdrawn Shares and must otherwise comply with DTC's procedures. All questions as to the form and validity (including time of receipt) of notices of withdrawal will be determined by Purchaser, in its sole discretion, and its determination will be final and binding on all parties. The receipt of cash in exchange for Shares pursuant to the Offer (or the Merger) will be a taxable transaction for U.S. federal income tax purposes and may also be a taxable transaction under applicable state, local or foreign tax laws.
