HAWKINS, SR. VICE PRES. & CFO (206) 448-1996 (360) 679-3121 NEWS RELEASE WASHINGTON BANKING COMPANY APPROVES STOCK REPURCHASE PLAN OAK HARBOR, WA - April 30, 1999 - Washington Banking Company (NASDAQ: WBCO), the holding company of Whidbey Island Bank, today reported its Board of Directors has approved a stock repurchase program. The approval authorizes a systematic program for the repurchase of up to 210,000 shares of the Company's outstanding common stock for cash in the open market and in privately negotiated transactions. The 210,000 shares represent nearly 5% of the Company's 4,200,300 shares of common stock outstanding at March 31, 1999. Assuming all the proposed shares are repurchased, there will be approximately 3,990,300 shares of WBCO common stock outstanding. After accounting for those held by officers and directors, there would be approximately 3,710,000 common shares available for trading in the public float following the repurchase. "Washington Banking Company is well positioned for growth with a strong capital position, good growth in earnings and assets, and sound asset quality," Michal D. Cann, President and Chief Executive Officer told shareholders at the annual meeting. "Since our initial public offering in June 1998, however, our stock has come under the same pressure as many small cap bank stocks, and we believe that the shares are undervalued. WBCO has closed at prices ranging from $8.25 to $10.19 in recent weeks - or 1.2 times and 1.4 times book value, respectively. At March 31, 1999, the Company's book value equaled $7.15 per share." At March 31, Washington Banking Company had assets of $229.5 million, loans of $163.2 million and total deposits of $198.5 million. Full results for the first quarter of 1999 are being reported in a separate press release. Repurchased shares will be held as Treasury Stock and be available for general corporate purposes such as providing available shares for the company's employee benefit plans, for issuance in connection with outstanding options and for possible resale in future public or private offerings. The repurchase program will be carried out in accordance with certain volume, timing and price constraints imposed by the Securities and Exchange Commission's rules applicable to such transactions. The amount, timing and price of purchases, if any, will otherwise depend on market conditions.
