In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

The undersigned also acknowledges that it may have to enter into a lock-up agreement or agreements with underwriters and/or placement agents engaged by the Company in connection with future financing(s) of the Company and the undersigned hereby agrees to execute such lock-up agreements in the form acceptable to the underwriters and/or placement agents.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

This Lock-Up Agreement sets forth the entire agreement of the parties with respect to its subject matter and supersedes all prior agreements, promises, covenants, arrangements, communications, representations or warranties, whether oral or written, by any officer, employee or representative of any party to this Lock-Up Agreement with respect to such subject matter. Should a dispute arise between the parties under or relating to this Lock-Up Agreement, each party agrees that prior to initiating any formal proceeding against the other (except when injunctive relief is appropriate), the parties will each designate a representative for purposes of resolving the dispute.  If the parties' representatives are unable to resolve the dispute within 14 business days, the dispute shall be settled by mediation and then, if necessary, by arbitration under the then-current commercial arbitration rules of the American Arbitration Association.  The location of the proceeding shall be in New York, NY. The award in any such arbitration shall be final, binding, conclusive and not appealable. Judgment upon any award rendered by the arbitrator may be entered by any court having jurisdiction thereof.

This Lock-Up Agreement may be executed in any number of counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party. In the event that any signature is delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of an executed signature page, such signature page shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof. Execution and delivery of this Agreement by facsimile or other electronic signature is legal, valid and binding for all purposes.

This Lock-Up Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.
