All capitalized terms used herein and not defined shall have the meanings ascribed to such terms in the Plan. RECITALS WHEREAS, the Board of Directors adopted the Plan on December 2, 1997; WHEREAS, Section 4 of the Plan provides for the reservation of 1,500,000 shares of the Company's common stock, $0.0005 par value per share (the "Common Stock"); WHEREAS, the Company's Board of Directors deems it advisable to increase the number of shares of the Common Stock reserved under the Plan from 1,5000,000 shares to 3,000,000 shares (the "Increase"); and WHEREAS, the Increase has been approved and adopted by the Company's Board of Directors and stockholders. NOW, THEREFORE, the Plan shall be amended as follows: 1. Section 4, titled "Stock Reserved for the Plan" is hereby amended to read in its entirety as follows: Subject to adjustment as provided in Section 7 hereof, a total of three million (3,000,000) shares of common stock, $.0005 par value ("Stock"), of the Company shall be subject to the Plan. The shares of Stock subject to the Plan shall consist of unissued shares or previously issued shares reacquired and held by the Company or any Subsidiary of the Company, and such amount of shares of Stock shall be and is hereby reserved for such purpose. Any of such shares of Stock which may remain unsold and which are not subject to outstanding Options at the termination of the Plan shall cease to be reserved for the purpose of the Plan, but until termination of the Plan the Company shall at all times reserve a sufficient number of shares of Stock to meet the requirements of the Plan. Should any Option expire or be canceled prior to its exercise in full or should the number of shares of Stock to be delivered uponthe exercise in full of any Option be reduced for any reason, the shares of Stock theretofore subject to such Option may again be subject to an Option under the Plan. Notwithstanding the foregoing, with respect to any options that are intended to qualify as performance-based compensation under Section 162(m) of the Code, the maximum number of shares of Stock that may be subject to options granted under the Plan to any individual in any calendar year shall not exceed 500,000, and the method of counting such shares shall conform to any requirements applicable to performance-based compensation under Section 162(m) of the Code.
