Options may be exercised only by delivery to the Company of a written exercise notice in a form approved by the Committee stating the number of Shares being purchased together with payment in full of the exercise price for the number of Shares being purchased. (b) PAYMENT. Payment for the Shares may be made (i) in cash (by check), (ii) by surrender of shares of common stock of the Company that have been owned by Optionee for more than six (6) months (and which have been paid for within the meaning of SEC Rule 144 and, -3- if such shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such shares) or were obtained by the Optionee in the open public market, having a Fair Market Value equal to the exercise price of the Option; (iii) by waiver of compensation due or accrued to Optionee for services rendered; (iv) through a "same day sale" commitment from the Optionee and a broker-dealer that is a member of the National Association of Securities Dealers (an "NASD DEALER") whereby the Optionee irrevocably elects to exercise the Option and to sell a portion of the Shares so purchased to pay for the exercise price and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the exercise price directly to the Company; (v) through a "margin" commitment from the Optionee and an NASD Dealer whereby the Optionee irrevocably elects to exercise the Option and to pledge the Shares so purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the exercise price, and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the exercise price directly to the Company; (vi) where permitted by applicable law and approved by the Committee in its sole discretion, by tender of a full recourse promissory note having such terms as may be approved by the Committee and bearing interest at a rate sufficient to avoid imputation of income under Sections 483 and 1274 of the Code; or (vii) by any combination of the foregoing where approved by the Committee in its sole discretion.

(ii) The Committee may specify a reasonable minimum number of Shares that may be purchased on any exercise of an Option, provided that such minimum number will not prevent the Optionee from exercising the full number of Shares as to which the Option is then exercisable. 9. NONTRANSFERABILITY OF OPTIONS. If an Option is an ISO, or if Optionee is an Insider subject to Section 16(b) of the Exchange Act, then an Option may not be transferred in any manner other than by will or by the law of descent and distribution and may be exercised during the lifetime of the Optionee only by the Optionee. Otherwise, an Option may only be transferred to Optionee's immediate family, to a trust for the benefit of Optionee or Optionee's immediate family, or to a charitable entity qualified under IRC Section 501(c), where "immediate family" shall mean spouse, lineal descendant or antecedent, brother or sister. The terms of this Option shall be binding upon the executors, administrators, successors and assigns of the Optionee. 10. PRIVILEGES OF STOCK OWNERSHIP.

The Company shall provide to each Optionee a copy of the annual financial statements of the Company, at such time after the close of each fiscal year of the Company as they are released by the Company to its shareholders. 11. ADJUSTMENT OF OPTION SHARES. In the event that the number of outstanding shares of common stock of the Company is changed by a stock dividend, stock split, reverse stock split, combination, reclassification or similar change in the capital structure of the Company without consideration, the number of Shares available under this Plan and the number of Shares subject to outstanding Options and the exercise price per share of such Options shall be proportionately adjusted, subject to any required action by the Board or shareholders of the Company and compliance with applicable securities laws; provided, however, that no certificate or scrip representing fractional shares shall be issued upon exercise of any Option and any resulting fractions of a Share shall be ignored. 12. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Option granted under this Plan shall confer on any Optionee any right to continue in the employ of the Company or any Parent, Subsidiary or Affiliate of the Company or limit in any way the right of the Company or any Parent, Subsidiary or Affiliate of the Company to terminate the Optionee's employment at any time, with or without cause. 13. COMPLIANCE WITH LAWS. The grant of Options and the issuance of Shares upon exercise of any Options shall be subject to and conditioned upon compliance with all applicable requirements of law, including without limitation compliance with the 1933 Act, any required approval by the Commissioner of Corporations of the State of California, compliance with all other applicable state securities laws and compliance with the requirements of any stock exchange or national market system on which the Shares may be listed. 14. ASSUMPTION OF OPTIONS BY SUCCESSORS. In the event of a dissolution or liquidation of the Company, a merger in which the Company is not the surviving corporation, or the sale of substantially all of the assets of the Company, any or all outstanding Options shall be assumed by the successor corporation or an equivalent option shall be substituted by such successor corporation which assumption or substitution shall be binding upon all Optionees. In the event of a merger in which the Company is not the surviving corporation and the successor corporation, if any, refuses to assume the Option or substitute an equivalent option, the Option shall accelerate and become exercisable in full at least ten days prior to and shall expire on, (and, if the Company has reserved to itself a right to repurchase shares issued upon exercise of Options at the original purchase price of such shares, such right shall terminate upon), the consummation of such merger at such times and on such conditions as the Committee shall determine.

Any remaining accelerated ISOs granted on or after January 1, 1987 shall be treated as NQSOs. 15. AMENDMENT OR TERMINATION OF PLAN. The Committee may at any time terminate or amend this Plan in any respect (including, but not limited to, any form of Grant, agreement or instrument to be executed pursuant to this Plan); provided, however, that the Committee shall not, without the approval of the shareholders of the Company, amend the Plan in any manner that requires such shareholder approval pursuant to the Code or the regulations promulgated thereunder as such provisions apply to this Plan or pursuant to the Exchange Act or Rule 16b-3 (or its successor) promulgated thereunder. In any case, no amendment of this Plan may adversely affect any then outstanding Options or any unexercised portions thereof without the written consent of the Optionee. -5- 16. TERM OF PLAN.
