("WIB") and its wholly-owned subsidiary Central Valley Bank, N.A. ("Bank"). Under the terms of the Agreement, Heritage and WIB will merge with Heritage surviving the merger. The Bank will become a separate wholly-owned commercial bank subsidiary of Heritage. The Agreement was approved by the boards of directors of Heritage, WIB and the Bank. The Agreement provides that all of the shares of outstanding common stock and all of the vested outstanding options of WIB are to be converted into and exchanged for between one million (1,000,000) and one million fifty thousand (1,050,000) shares of Heritage Common Stock, depending on Heritage's average stock price computed for 45 trading days just prior to the date the transaction closes. WIB may elect to terminate the transaction if Heritage's average stock price computed for that period is below $10.00 per share unless Heritage increases the number of shares of Heritage Common Stock to be issued in the transaction. Consummation of the acquisition is subject to several conditions, including, among other things, receipt of applicable regulatory approvals, approvals by shareholders of Heritage and WIB, and the receipt of fairness opinions. The transaction is expected to be completed by January 31, 1999.
