This option shall be exercisable during its term in accordance with the provisions of Section 7 of the Plan as follows:

(i): RIGHT TO EXERCISE

(a) Subject to subsections 3(i)(b), (c) and (d), below:

•: if you are an existing Sun Microsystems, Inc. employee, this option shall be exercisable cumulatively, to the extent of 20% of the Shares subject to the option on or after (one year after date of grant) and to the extent of an additional 20% of the Shares on each yearly anniversary of such date thereafter.
•: if this option was granted in connection with you becoming a Sun Microsystems, Inc. employee (new hire or rehire grant), this option will become exercisable cumulatively, to the extent of 20% of the Shares subject to the option on or after one year from your hire date and to the extent of an additional 20% of the Shares on each yearly anniversary of such date thereafter.

(b) Notwithstanding subsection 3(i)(a), above, and subject to subsections 3(i)(c), 7 and 8, below, in the event of Optionee's death or disability, this option shall be exercisable cumulatively, to the extent of 1.6667% of the Shares subject to the option on or after one month following the date of grant and to the extent of an additional 1.6667% of the Shares on each monthly anniversary of such date thereafter.

(d) In the event of Optionee's termination of employment, the exercisability of the option is governed by Section 6, below.

(ii): METHOD OF EXERCISE

This option shall be exercisable by written notice which shall state the election to exercise the option, the number of Shares in respect of which the option is being exercised, and such other representations and agreements as to the holder's investment intent with respect to such shares of Common Stock as may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be signed by the Optionee, shall be delivered in person or by certified mail to the Treasury Department of the Company, and shall be accompanied by payment of the purchase price.

4.: METHOD OF PAYMENT

Payment of the purchase price shall be by any of the following, or a combination thereof, at the election of the Optionee: cash, check, or surrender of other shares of Common Stock of the Company of a value equal to the purchase price of the shares as to which the option is exercised; or the Optionee may elect to transact a "same-day -sale"—thereby executing a "cashless" option exercise, provided such a sale does not violate any applicable federal or state laws or regulations.

5.: RESTRICTIONS ON EXERCISE

This option may not be exercised if the issuance of such shares upon such exercise would constitute a violation of any applicable federal or state securities or other law or regulation, including any rule under Regulation G as promulgated by the Federal Reserve Board. As a condition to the exercise of this option, the Company may require the Optionee to make any representation and warranty to the Company as may be required by any applicable law or regulation.

(i): GENERAL RULE

Subject to subsection 6(ii) below, if Optionee ceases to serve as an Employee, Optionee may, but only within 90 days after the date Optionee ceases to be an Employee of the Company, exercise his/her option to the extent that Optionee was entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the option at the date of such termination, or if Optionee does not exercise the option within the time specified herein, the option shall terminate.

(ii): RETIREMENT

Notwithstanding subsection 6(i) above, in the case of an Optionee who is not in a job classification of director-level or above and who ceases to serve as an Employee by reason of retirement (as defined below), then for purposes of this Agreement, the Option shall remain outstanding and shall be exercisable as though the Optionee had remained in Continuous Status as an Employee for twelve (12) months after the date of retirement.

hereof had the Optionee continued living and remained in Continuous Status as an Employee for twelve (12) months after the date of death; or (ii) within one (1) month after the termination of the Optionee's Continuous Status as an Employee, the option may be exercised, at any time within six (6) months following the date of death, by the Optionee's estate or by a person who acquired the right to exercise the option by bequest or inheritance, but only to the extent of the right to exercise that had accrued in accordance with Section 3(i)(b) hereof at the date of termination.
