WHEREAS, Affiliate is a shareholder and an officer and director of Parent. WHEREAS, Parent, Syracuse Acquisition Sub, Inc., a California corporation and a wholly-owned subsidiary of Parent ("MERGER SUB"), and Company have entered into an Agreement and Plan of Merger and Reorganization dated as of March 1, 1998 (the "MERGER AGREEMENT"), providing for the merger of Merger Sub with and into the Company (the "MERGER"). The Merger Agreement contemplates that, upon consummation of the Merger, (i) the holders of the common stock of the Company ("COMPANY COMMON STOCK") will receive shares of common stock of Parent ("PARENT COMMON STOCK") in exchange for their shares of Company Common Stock and (ii) the Company will become a wholly-owned subsidiary of Parent. WHEREAS, it is a condition to the consummation of the Merger pursuant to the Merger Agreement that the independent accounting firms that audit the annual financial statements of Parent and the Company will have delivered the written concurrences with the conclusions of management of Parent and the Company to the effect that the Merger will be accounted for as a pooling of interests under Accounting Principles Board Opinion No. 16. NOW, THEREFORE, intending to be legally bound, in order to induce the Company and Parent to consummate the transactions contemplated by the Merger Agreement, and for other valuable consideration, the receipt and sufficiently of which are hereby acknowledged by Affiliate, Affiliate hereby covenants and agrees as follows: SECTION 1. REPRESENTATIONS AND WARRANTIES. Affiliate represents and warrants to Parent as follows: (a) Affiliate is the holder and "beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of the number of shares of the Parent Common Stock set forth under Affiliate's signature below (the "PARENT SHARES"), and Affiliate has good and valid title to the Parent Shares, free and clear of any liens, pledges, security interests, adverse claims, equities, options, proxies, charges, encumbrances or restrictions of any nature. (b) Affiliate has carefully read this Agreement, and has discussed with Affiliate's own independent counsel to the extent Affiliate felt necessary the limitations imposed on Affiliate's ability to sell, transfer or otherwise dispose of the shares of Parent Common Stock. Affiliate fully understands the limitations this Agreement places upon Affiliate's ability to sell, transfer or otherwise dispose of the Parent Shares. 1. (c) Affiliate understands that the representations, warranties and covenants set forth herein will be relied upon by Parent, the Company, and their respective affiliates, counsel and accounting firms for purposes of determining Parent's eligibility to account for the Merger as a "pooling of interests," and that substantial losses and damages may be incurred by these persons if Affiliate's representations, warranties or covenants are breached. SECTION 2. COVENANTS RELATED TO POOLING OF INTERESTS. In accordance with SEC Staff Accounting Bulletin No. 65 ("SAB 65"), during the period contemplated by SAB 65, until the earlier of (i) Parent's public announcement of financial results covering at least 30 days of combined operations of Parent and the Company or (ii) the Merger Agreement is terminated in accordance with its terms, Affiliate will not sell, exchange, transfer, pledge, distribute or otherwise dispose of or grant any option, establish any "short" or put-equivalent position with respect to or enter into any similar transaction (through derivatives or otherwise) intended or having the effect, directly or indirectly, to reduce its risk relative to any Parent Common Stock. Parent may, at its discretion, place a stock transfer notice consistent with the restrictions referred to in this Section 2 with its transfer agent with respect to such certificates, provided such restrictive legend shall be removed and/or notice shall be countermanded promptly upon expiration of the necessity therefor at the request of Affiliate. SECTION 3. PERMITTED TRANSFERS. Notwithstanding anything to the contrary contained in this Agreement, Affiliate may (i) transfer Affiliate's pro rata portion (of the total number of shares available under the "de minimis" exception referred to in this clause (i) to all affiliates of Parent and Company) of the "de minimis" amount of Company Common Stock and Parent Common Stock available for sale in accordance with SEC Staff Accounting Bulletin No. 76 (the "DE MINIMIS POOL") contingent upon confirmation by legal counsel for Parent and independent auditors for Parent and the Company as to whether such transfer qualifies as within Affiliate's pro rata portion of the De Minimis Pool and (ii) may (with the written consent of Parent, not to be unreasonably withheld): (A) transfer shares of Parent Common Stock in payment of the exercise price of options to purchase Parent Common Stock; (B) transfer shares of Parent Common Stock to any organization qualified under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended, so long as such organization has traditionally been supported by contributions from the general public (as opposed to being supported largely by a specific donor); and (C) transfer shares of Parent Common Stock to a trust established for the benefit of Affiliate and/or for the benefit of one or more members of Affiliate's family, or make a bona fide gift of Parent Common Stock to one or more members of Affiliate's family, provided that in the case of a transfer or gift pursuant to this clause (B) or (C), a transferee of such shares agrees to be bound by the limitations set forth in this Agreement.
