DRAG-ALONG RIGHT (a) If, prior to the consummation of a Qualified Public Offering, (i) stockholders of the Company holding more than 50% of the outstanding Shares (assuming all Options are exercised) (the "DRAG-ALONG GRANTEES") enter into an agreement with any Person or Persons, to Transfer (pursuant to a merger or otherwise) all Shares then held by the Drag-Along Grantees, the Drag-Along Grantees shall be entitled, at their option, to require each Optionee to sell all Shares held by such Optionee (together with all Options then outstanding and held by such Optionee), by providing such holders with notice at least fifteen days prior to consummation of the proposed transaction, setting forth in reasonable detail the material terms and conditions of the proposed transaction or offering, and the price per share at which such holder shall be required to sell all of his or her Shares (which price per share shall be equal to the same price per share that the Drag-Along Grantees shall receive pursuant to the proposed transaction).

An Optionee (or other person, as provided in Section 16(c)) may exercise a Vested Option granted under this Plan in whole or in part (but for the purchase of whole Shares only), as provided in the Option Agreement evidencing his Option, by delivering a written notice (the "NOTICE") to the Secretary of the Company. The Notice shall state: (i) that the Optionee elects to exercise the Vested Option; (ii) the number of Shares with respect to which the Vested Option is being exercised (the "OPTIONED SHARES"); (iii) the method of payment for the Optioned Shares (which method must be available to the Optionee under the terms of his or her Option Agreement); (iv) the date upon which the Optionee desires to consummate the purchase (which date must be prior to the termination of such Option); (v) a copy of any election filed by the Optionee pursuant to Section 83(b) of the Code; and (vi) such further provisions consistent with this Plan as the Committee may from time to time require.

ADJUSTMENTS (a) CHANGES IN CAPITAL STRUCTURE. If the Common Stock is changed by reason of a stock split, reverse stock split or stock combination, stock dividend or distribution, or recapitalization, or converted into or exchanged for other securities as a result of a merger, consolidation or reorganization (each such event being a "RECAPITALIZATION"), the Committee shall make such adjustments in the number and class of shares of stock available under this Plan as shall be necessary to preserve to an Optionee rights substantially proportionate to his rights existing immediately prior to such transaction or event (but subject to the limitations and restrictions on such rights), including, without limitation, a corresponding adjustment changing the number and 16 class of shares allocated to, and the Option Price of, each Option or portion thereof outstanding at the time of such change and the number of shares that vest pursuant to this Plan. (b) SPECIAL RULES. The following rules shall apply in connection with Section 15(a) above: (i) no adjustment shall be made for cash dividends or the issuance to stockholders of rights to subscribe for additional Shares; and (ii) any adjustments referred to in Section 15(a) shall be made by the Committee in its sole and absolute discretion, and shall be conclusive and binding on all persons holding any Options granted under this Plan. 16. RESTRICTIONS ON OPTIONS AND OPTIONED SHARES. (a) No Options shall be granted under this Plan, and no Shares shall be issued and delivered upon the exercise of Options granted under this Plan, unless and until the Company and/or the Optionee shall have complied with all applicable Federal or state registration, listing and/or qualification requirements and all other requirements of law or of any regulatory agencies having jurisdiction. (b) The Committee in its sole and absolute discretion may, as a condition to the exercise of any Vested Option granted under this Plan, require an Optionee (i) to represent in writing that the Shares received upon exercise of a Vested Option are being acquired for investment and not with a view to distribution and (ii) to make such other representations and warranties as are reasonably deemed appropriate by the Company to satisfy the requirements of applicable law, including, without limitation, an applicable private placement exemption of the Securities Act as determined by the Committee. Stock certificates representing Shares acquired upon the exercise of Vested Options that have not been registered under the Securities Act shall, if required by the Committee, bear the following legend and such additional legends as may be required by the Option Agreement evidencing a particular Option: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"). THE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE PLEDGED, HYPOTHECATED, SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SHARES UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL TO THE ISSUER HEREOF THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT." (c) No Option granted under this Plan may be Transferred by the Optionee, except by will or by the laws of descent and distribution. A Vested Option may be exercised during the lifetime of the Optionee only by the Optionee. If an Optionee dies, his or her Vested Options shall thereafter be exercisable, during the period specified in Section 9(d) or the applicable Option Agreement (as the case may be), by his or her executors or administrators to the full 17 extent (but only to such extent) to which such Options were exercisable by the Optionee at the time of his or her death. (d) No Share issued upon exercise of an Option may be Transferred, except otherwise provided in this Plan, by will, by the laws of descent and distribution or to the Company or any of the Company's affiliates. 17. EFFECTIVE DATE AND TERMINATION OF THE PLAN. (a) This Plan shall become effective on the Effective Date. (b) No Options may be granted after the tenth anniversary of the Effective Date. (c) Any Option outstanding as of the tenth anniversary of the Effective Date shall remain in effect until the earlier of the exercise thereof and the Expiration Date with respect to such Option. 18. WITHHOLDING TAXES. Whenever under this Plan, Shares are to be delivered to an Optionee, the Company shall be entitled to require as a condition of delivery that the Optionee remit or, in appropriate cases, agree to remit when due, an amount sufficient to satisfy all current or estimated future Federal, state and local withholding tax and employment tax requirements relating thereto. 19. MISCELLANEOUS Each Option granted under this Plan may contain such other terms and conditions not inconsistent with this Plan as may be determined by the Committee, in its sole and absolute discretion. (a) NUMBER AND GENDER. With respect to words used in this Plan, the singular form shall include the plural form, the masculine gender shall include the feminine gender, and vice-versa, as the context requires. (b) CAPTIONS. The use of captions in this Plan is for convenience. The captions are not intended to provide substantive rights. (c) AMENDMENT OF PLAN. This Plan may be modified or amended in any respect by the Board, with the prior written consent of the Requisite Holders (as defined in the Stockholders Agreement). (d) GOVERNING LAW. All questions concerning the construction, interpretation and validity of this Plan and the instruments evidencing the Options granted hereunder shall be governed by and construed and enforced in accordance with the domestic laws of the State of New York, without giving effect to any choice or conflict of law provision or rule (whether in 18 the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York. In furtherance of the foregoing, the internal law of the State of New York will control the interpretation and construction of this Plan, even if under such jurisdiction's choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply. (e) SECURITIES EXCHANGE ACT COMPLIANCE. The Corporation will use its commercially reasonable efforts to cause the exemption from Section 16 of the 1934 Act afforded by such Rule 16b-3 to be available at the time the Company has a class of equity securities registered under Section 12 of the 1934 Act. (f) NO EVIDENCE OF EMPLOYMENT OR SERVICE Nothing contained in this Plan or in any Option Agreement shall confer upon any Optionee any right with respect to the continuation of his or her employment by or service with the Company or any of its Subsidiaries or interfere in any way with the right of the Company or any such Subsidiary (subject to the terms of any separate agreement to the contrary) at any time to terminate such employment or service or to increase or decrease the compensation of the Optionee from the rate in existence at the time of the grant of an Option. 19 EXHIBIT A LIST OF OPTIONEES AND NUMBER OF OPTIONS AWARDED Richard N.
