You accept this Option in conversion and exchange for your prior HML options. Such number of shares (as such may be adjusted as described in Section 10 below) is herein referred to as the "Option Shares". This Option shall constitute and be treated as a "non-qualified stock option" as described in Treasury Regulation Section 1.83-7 for federal income tax purposes. The terms and conditions of this Option are set out below. You further agree that this Option will be deemed subject to the terms and conditions of the Company's 1996 Stock Option Plan (the "Plan"). 1. Date of Grant. This Option is granted to you as of the "Grant Date" set forth on the Grant Detail Report (which is the initial date of grant of the Assumed Options). 2. Termination of Option. Your right to exercise this Option (and to purchase the Option Shares) shall expire and terminate in all events on the earliest to occur of: (i) the "Expiration Date" set forth on the Grant Detail Report; or (ii) the date provided in Sections 8(a), 8(b) or 8(c) below in the event you cease to be employed on a full-time basis by the Company or any Subsidiary of the Company (as defined in the Plan). 3. Option Price. The purchase price to be paid upon the exercise of this Option shall be the "Option Price" set forth on the Grant Detail Report, which represents the exercise price per share of the Assumed Options as converted pursuant to the terms of the Merger Agreement. 4. Vesting Provisions. This option shall vest and thereupon become exercisable in accordance with the schedule set forth Page 1 of 5 2 under the captions "Options Vested" and "Options Becoming Exercisable" on the Grant Detail Report, which is the same vesting schedule as the Assumed Options. 5. Additional Provisions Relating to Exercise. (a) Once you become entitled to exercise this Option (and purchase Option Shares) as provided in Section 4 hereof, such right will continue until the date on which this Option expires and terminates pursuant to Section 2 hereof. (b) The Committee, in its sole discretion, may at any time accelerate the time at which this Option may be exercised by you with respect to any Option Shares. In furtherance of the foregoing, in the event of: (i) a sale or other disposition of more than 50% of the outstanding Common Stock of the Company to an unrelated and unaffiliated third party purchaser, other than in connection with an underwritten public offering registered under the Securities Act of 1933, as amended ( a "Stock Sale") or, (ii) a sale of substantially all of the assets of the Company (as determined by the Board of Directors of the Company) to an unrelated and unaffiliated third party purchase (an "Asset Sale"), in which the purchaser, in the case of either a Stock Sale or an Asset Sale, does not offer to substitute new or substantially equivalent stock options with respect to all Option Shares which you had theretofore not otherwise become entitled to purchase hereunder ("Unvested Option Shares"), then if the Board of Directors of the Company determines that the Company had achieved not less than 90% of its business plan immediately preceding the completion of such Stock Sale or Asset Sale, as the case may be, the Committee may (but shall in no event be required to), in its sole discretion, thereupon permit you to exercise this Option with respect to 50% of such Unvested Option Shares. In connection with the foregoing, you hereby understand and acknowledge that the terms of the preceding sentence shall not be binding on the Board of Directors of the Company of the Committee. 6.

Payment of the option price must be made in cash or by check or by use of any cashless stock option exercise program offered by the Company through a brokerage firm. (b) At the time of the exercise, you will recognize as taxable ordinary income (compensation income), an amount equal to the excess of the fair market value of the exercised option shares on the date of exercise over the exercise price. 7. Transferability of Option. This Option may not be transferred by you (other than by will or the laws of descent and distribution) and may be exercised during your lifetime only by you. 8.

In such event, this Option may be exercised during such one year period by the executor or administrator of your estate or by any person who shall have acquired the Option through bequest or inheritance, but only to the same extent that you were entitled to exercise this Page 3 of 5 4 Option immediately prior to the time of your death and you had not previously done so. (d) Notwithstanding any provisions contained in this Section 8 to the contrary, in no event may this Option be exercised to any extent by anyone after the Expiration Date. 9. Representations.
