Grant Subject to Plan. This option is granted under and is expressly subject to, all the terms and provisions of the Plan, which terms are incorporated herein by reference.

Grant and Terms of Option.

During the term of this option, Optionee may purchase shares to which this option relates in accordance with the Option Vesting Schedule (Schedule A) attached hereto. In no event may this option or any part thereof be exercised after the expiration of five (5) years from the Date of Grant.

No shares of Common Stock may be tendered in exercise of this option if such shares were acquired by Optionee through the exercise of an Incentive Stock Option, unless (i) such shares have been held by Optionee for at least one year, and (ii) at least two years have elapsed since such Incentive Stock Option was granted. 3. Anti-Dilution Provisions. In the event that, during the term of this Agreement, there is any change in the number of shares of outstanding Common Stock of the Company by reason of stock dividends, recapitalizations, mergers, consolidations, split-ups, combinations or exchanges of shares and the like, the number of shares covered by this option agreement and the price thereof shall be adjusted, to the same proportionate number of shares and price as in this original agreement. 4. Investment Purpose. Optionee represents that, in the event of the exercise by Optionee of the option hereby granted, or any part thereof, Optionee intends to purchase the shares acquired on such exercise for investment and not with a view to resale or other distribution; except that the Committee, at its election, may waive or release this condition in the event the shares acquired on exercise of the option are registered under the Securities Act of 1933, or upon the happening of any other contingency which the Committee shall determine warrants the waiver or release of this condition. Optionee agrees that the certificates evidencing the shares acquired by him on exercise of all or any part of this option, may bear a restrictive legend, if appropriate, indicating that the shares have not been registered under said Act and are subject to restrictions on the transfer thereof, which legend may be in the following form (or such other form as the Company shall determine to be proper), to-wit: "The shares represented by this certificate have not been registered under the Securities Act of 1933, but have been issued or transferred to the registered owner pursuant to the exemption afforded by Section 4(2) of said Act. No transfer or assignment of these shares by the registered owner shall be valid or effective, and the issuer of these shares shall not be required to give any effect to any transfer or attempted transfer of these shares, including without limitation, a transfer by operation of law, unless (a) the issuer shall have received an opinion of its counsel that the shares may be transferred without requirement of registration under said Act, or (b) there shall have been delivered to the issuer a 'no-action' letter from the staff of the Securities and Exchange Commission, or (c) the shares are registered under said Act." 5. Non-Transferability. Neither the option hereby granted nor any rights thereunder or under this Agreement may be assigned, transferred or in any manner encumbered except by will or the laws of descent and distribution, and any attempted assignment, transfer, mortgage, pledge or encumbrance except as herein authorized, shall be void and of no effect. The option may be exercised during Optionee's lifetime only by him. 6. Termination of Employment. In the event of the termination of employment of Optionee other than by death, the option granted may be exercised at the times and to the extent provided in Section 7(f) of the Plan. 7. Death of Optionee. In the event of the death of Optionee, the option granted may be exercised at the times and to the extent provided in Section 7(g) of the Plan. 8.

Committee Administration. This option has been granted pursuant to a determination made by the Committee, and such Committee or any successor or substitute committee authorized by the Board of Directors or the Board of Directors itself, subject to the express terms of this option, shall have plenary authority to interpret any provision of this option and to make any determinations necessary or advisable for the administration of this option and the exercise of the rights herein granted, and may waive or amend any provisions hereof in any manner not adversely affecting the rights granted to Optionee by the express terms hereof. 10. Option an Incentive Stock Option. This option is intended as, and shall be treated as, an incentive stock option under Section 422 of the Internal Revenue Code of 1986, as amended. 11. Choice of Law.
