(i) Subject to Section 4(a) of this Agreement, the Vested Portion of an Option may be exercised by delivering to the Company at its principal office written notice of intent to so exercise; provided that the Option may be exercised with respect to whole Shares only. Such notice shall specify the number of Shares for which the Option is being exercised and, other than as described in clause (C) of the following sentence, shall be accompanied by payment in full of the aggregate Option Price in respect of such Shares. Payment of the aggregate Option Price may be made (A) in cash, or its equivalent (e.g., a check), (B) by transferring to the Company Shares having a Fair Market Value equal to the aggregate Option Price for the Shares being purchased and satisfying such other requirements as may be imposed by the Committee; provided that such Shares have been held by the Participant for no less than six months (or such other period as established from time to time by the Committee or generally accepted accounting principles), (C) if there is a public market for the Shares at the time of payment, subject to such rules as may be established by the Committee, through delivery of irrevocable instructions to a broker to sell the Shares otherwise deliverable upon the exercise of the Option and deliver promptly to the Company an amount equal to the aggregate Option Price or (D) by a combination of (A) and (B) above or such other method as approved by the Committee. No Participant shall have any rights to dividends or other rights of a stockholder with respect to the Shares subject to an Option until the Participant has given written notice of exercise of the Option, paid in full for such Shares or otherwise completed the exercise transaction as described in the preceding sentence and, if applicable, has satisfied any other conditions imposed pursuant to this Agreement.

(ii) Notwithstanding any other provision of the Plan or this Agreement to the contrary, absent an available exemption to registration or qualification, an Option may not be exercised prior to the completion of any registration or qualification of the Option or the Shares under applicable state and federal securities or other laws, or under any ruling or regulation of any governmental body or national securities exchange that the Committee shall in its sole reasonable discretion determine to be required by such laws, rulings or regulations.

(iii) Upon the Company’s determination that an Option has been validly exercised as to any of the Shares, the Company shall issue certificates in the Participant’s name for such Shares. However, the Company shall not be liable to the Participant for damages relating to any reasonable delays in issuing the certificates to the Participant or any loss by the Participant of the certificates.

(iv) In the event of the Participant’s death, the Vested Portion of an Option shall remain vested and exercisable by the Participant’s executor or administrator, or the person or persons to whom the Participant’s rights under this Agreement shall pass by will or by the laws of descent and distribution as the case may be, to the extent set forth in Section 4(a) of this Agreement. Any heir or legatee of the Participant shall take rights herein granted subject to the terms and conditions hereof.

(v) As a condition to the exercise of any Option evidenced by this Agreement, the Participant shall execute the Stockholders Agreement, if then in effect.

5. Adjustments. In the event of any change in the outstanding Shares after the Effective Date by reason of any Share dividend or split, reorganization, recapitalization, merger, consolidation, spin-off, combination or transaction or exchange of Shares or other corporate exchange, or in the event of any distribution to shareholders of Shares (other than regular cash dividends or any synthetic secondary offering following an initial public offering of the Shares) or any transaction similar to the foregoing or the issuance of equity (or rights to acquire equity) for consideration less than Fair Market Value (other than equity-based compensation or the conversion of preferred shares of the Company to Shares), the Committee in its sole discretion and without liability to any person may make such substitution or adjustment, if any, as it deems to be equitable, to the Option; provided, that in the event of an extraordinary dividend or similar extraordinary distribution (excluding an initial public offering of the Shares and any synthetic secondary offerings), in lieu of any other adjustment or substitution, the Participant shall be entitled to receive, with respect to each Share subject to the Vested Portion of the Option as of such distribution, an amount equal to such extraordinary dividend or distribution paid with respect to a Share (whether paid in cash or otherwise), such amount to be paid when such distribution is paid to shareholders of the Company.

6. No Right to Continued Employment. Neither the Plan nor this Agreement shall be construed as giving the Participant the right to be retained in the employ of, or in any consulting relationship to, the Company or any Affiliate. Further, the Company or its Affiliate may at any time terminate the Participant or discontinue any consulting relationship, free from any liability or any claim under the Plan or this Agreement, except as otherwise expressly provided herein.

7. Legend on Certificates. The certificates representing the Shares purchased by exercise of an Option shall be subject to such stop transfer orders and other restrictions as the Committee may determine is required by the rules, regulations, and other requirements of the Securities and Exchange Commission, any stock exchange upon which such Shares are listed, any applicable federal or state laws and the Company’s Certificate of Incorporation and Bylaws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

8. Transferability. Unless otherwise determined by the Committee, an Option may not be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by the Participant otherwise than by will or by the laws of descent and distribution, and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate; provided that the

designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance. During the Participant’s lifetime, an Option is exercisable only by the Participant.

9. Withholding. The Participant may be required to pay to the Company or its Affiliate and the Company or its Affiliate shall have the right and is hereby authorized to withhold from any payment due or transfer made under the Option or under the Plan or from any compensation or other amount owing to a Participant the amount (in cash, Shares, other securities, other Awards or other property) of any applicable withholding taxes in respect of the Option, its exercise, or any payment or transfer under the Option or under the Plan and to take such action as may be necessary in the option of the Company to satisfy all obligations for the payment of such taxes.
