EXERCISE OF OPTION. (i) RIGHT TO EXERCISE. The Option shall first become exercisable on the Initial Exercise Date. The Option shall be exercisable on and after the Initial Exercise Date and prior to the termination of the Option in the amount equal to the Number of Option Shares multiplied by the Vested Ratio as set forth in paragraph 1 above less the number of shares previously acquired upon exercise of the Option. In no event shall the Option be exercisable for more shares than the Number of Option Shares. In addition to the foregoing, in the event that the adoption of the Plan or any amendment of the Plan is subject to the approval of the Company's stockholders in order for the Option to comply with the requirements of Rule 16b-3, promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the Option shall not be exercisable prior to such stockholder approval if the Optionee is subject to Section 16(b) of the Exchange Act, unless the Board, in its sole discretion, approves the exercise of the Option prior to such stockholder approval. (ii) METHOD OF EXERCISE. The Option may be exercised by written notice to the Company which must state the election to exercise the Option, the number of shares for which the Option is being exercised and such other representations and agreements as to the Optionee's investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement. The written notice must be signed by the Optionee and must be delivered in person or by certified or registered mail, return receipt requested, to the Chief Financial Officer of the Company, or other authorized representative of the Participating Company Group, prior to the termination of the Option as set forth in paragraph 6 below, accompanied by full payment of the exercise price for the number of shares being purchased. (iii) FORM OF PAYMENT OF OPTION PRICE. Such payment shall be made (i) in cash, by check, or cash equivalent, (ii) by tender to the Company of shares of the Company's common stock owned by the Optionee having a value not less than the option price, which either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly, from the Company, (iii) by Immediate Sales Proceeds, as defined below, or (iv) by any combination of the foregoing. Notwithstanding the foregoing, the Option may not be exercised by tender to the Company of shares of the Company's common stock to the extent such tender of stock would constitute a violation of the provisions of any law, regulation and/or agreement restricting the redemption of the Company's common stock. "Immediate Sales Proceeds" shall mean the assignment in form acceptable to the Company of the proceeds of a sale of some or all of the shares acquired upon the exercise of the Option pursuant to a program and/or procedure approved by the Company (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System). The Company reserves, at any and all times, the right, in the Company's sole and absolute discretion, to decline to approve any such program and/or procedures. (iv) TAX WITHHOLDING. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company, the Optionee hereby authorizes withholding from -3- payroll and any other amounts payable to the Optionee, and otherwise agrees to make adequate provision for, any sums required to satisfy the foreign, federal and state tax withholding obligations of the Company, if any, which arise in connection with the Option, including, without limitation, obligations arising upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in whole or in part, of any shares acquired on exercise of the Option, (iii) the operation of any law or regulation providing for the imputation of interest, or (iv) the lapsing of any restriction with respect to any shares acquired on exercise of the Option. The Optionee is cautioned that the Option is not exercisable unless the tax withholding obligations of the Company are satisfied. Accordingly, the Optionee may not be able to exercise the Option when desired even though the Option is vested, and the Company shall have no obligation to issue a certificate for such shares or release such shares from any escrow. (v) CERTIFICATE REGISTRATION. The certificate or certificates for the shares as to which the Option shall be exercised shall be registered in the name of the Optionee, or, if applicable, the heirs of the Optionee. (vi) RESTRICTIONS ON GRANT OF THE OPTION AND ISSUANCE OF SHARES. The grant of the Option and the issuance of the shares upon exercise of the Option shall be subject to compliance with all applicable requirements of foreign, federal or state law with respect to such securities. The Option may not be exercised if the issuance of shares upon such exercise would constitute a violation of any applicable foreign, federal or state securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the shares may then be listed. In addition, no Option may be exercised unless (i) a registration statement under the Securities Act of 1933, as amended (the "Securities Act"), shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the share issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISABLE UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. Questions concerning this restriction should be directed to the Chief Financial Officer of the Company. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company's legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. (vii) FRACTIONAL SHARES. The Company shall not be required to issue fractional shares upon the exercise of the Option. -4- 23. NON-TRANSFERABILITY OF THE OPTION.

If the Optionee's employment with the Participating Company Group is terminated because of death or disability of the Optionee within the meaning of Section 422(c) of the Code, the Option, to the extent unexercised, and exercisable by the Optionee (or the Optionee's legal representative) at any time prior to the expiration of six (6) months from the date on which the Optionee's employment terminated, but in any event no later than the Option Term Date. The Optionee's employment shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee's termination of employment.

In the event of a Transfer of Control, the Board, in its sole discretion, may arrange with the surviving, continuing, successor, or purchasing Corporation or parent Corporation thereof, as the case may be (the "Acquiring Corporation"), for the Acquiring Corporation to assume the Company's rights and obligations under the Option or substitute options for the Acquiring Corporation's stock for the Option.

In the event of any such amendment, the number of shares and the exercise price shall be adjusted in a fair and equitable manner. 28. RIGHTS AS A STOCKHOLDER OR EMPLOYEE. The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate or certificates for the shares for which the Option has been exercised. No adjustment shall be made for dividends or distributions or other rights for which the record date is prior to the date such certificate or certificates are issued, except as provided in paragraph 9 above.
