Except as otherwise provided in this Section 2, (i) twenty-five percent (25%) of the Restricted Stock shall vest on the first anniversary of the Effective Date, and (ii) the remaining seventy-five percent (75%) of the Restricted Stock shall vest in equal monthly installments on the next thirty-six (36) monthly anniversary dates thereafter; provided that the Participant remains in continuous employment or other service with the Company (or its Affiliates) through each applicable vesting date.

Except as otherwise provided in this Section 2, upon termination of the Participant’s employment or other service with the Company and its Affiliates for any reason: (i) any shares of Restricted Stock that have not, on or prior to the date of such termination, become vested will immediately and automatically, without any action on the part of the Company, be forfeited and returned to the Company, without payment therefore by the Company, and (ii) the Participant will have no further rights with respect to those shares. A military or sick leave or other bona fide leave shall not be deemed a termination of employment or other service, if it does not exceed the longer of (i) ninety (90) days or (ii) the period during which Participant’s reemployment rights, if any, are guaranteed by statute or by contract.

3.          Certificated Shares. The shares of Restricted Stock shall be issued in the form of certificated shares.

After any of shares of Restricted Stock vest pursuant to this Agreement, such shares will remain subject to the terms of the Plan.

5.          Capital Changes.

(f)          The Company is under no obligation to register the Restricted Stock on behalf of the Participant or to assist the Participant in complying with any exemption from registration.

10.         Lock-Up Agreement.      The Participant hereby agrees that in the event that any directors or officers of the Company have agreed with one or more underwriters not to sell securities of the Company, then the Participant, upon request from the Company, shall enter into an agreement, in form and substance satisfactory to the Company, pursuant to which the Participant shall agree to restrictions on transferability of the Restricted Stock, whether or not then vested, comparable to the restrictions agreed upon by such directors or officers of the Company.

(d)          Any notice required or permitted to be given by either the Company or the Participant pursuant to the terms of this Agreement shall be in writing and shall be deemed given on the date and at the time delivered via personal, courier or recognized overnight delivery service or, if sent via telecopier, on the date and at the time telecopied with confirmation of delivery or, if mailed, on the date five (5) days after the date of the mailing (which shall be by regular, registered or certified mail). Delivery of a notice by telecopy (with confirmation) shall be permitted and shall be considered delivery of a notice notwithstanding that it is not an original that is received. If directed to the Participant, any such notice shall be sent to the address on file with the Company, or to such other address as the Participant may hereafter specify in writing. If directed to the Company, any such notice shall be sent to the Company’s principal executive office, c/o the Company’s Secretary, or to such other address or person as the Company may hereafter specify in writing.

(e)          Neither this Agreement nor any rights or interest hereunder shall be assignable by the Participant, his beneficiaries or legal representatives, and any purported assignment in violation hereof shall be null and void.

(f)          Either party’s failure to enforce any provision or provisions of this Agreement shall not in any way be construed as a waiver of any such provision or provisions, nor prevent that party thereafter from enforcing each and every other provision of this Agreement. The rights granted both parties herein are cumulative and shall not constitute a waiver of either party’s right to assert all other legal remedies available to it under the circumstances.

(g)          The grant of Restricted Stock hereunder will not confer upon the Participant any right to continue in the employment or other service of the Company or any of its Affiliates.

(h)          This Agreement shall be governed by and construed in accordance with the laws and judicial decisions of the State of Delaware, without regard to the application of the principles of conflicts of laws of Delaware or any other jurisdiction.
