Any attempted transfer in violation of this Lock-Up Agreement will be of no effect and null and void, regardless of whether the purported transferee has any actual or constructive knowledge of the transfer restrictions set forth in this Lock-Up Agreement, and will not be recorded on the share register of Public Company. In furtherance of the foregoing, the undersigned agrees that Public 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. Public Company may cause the legend set forth below, or a legend substantially equivalent thereto, to be placed upon any certificate(s) or other documents, ledgers or instruments evidencing the undersigned’s ownership of Public Company Common Stock:

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AND MAY ONLY BE TRANSFERRED IN COMPLIANCE WITH A LOCK-UP AGREEMENT, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

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.

The undersigned understands that if the Merger Agreement is terminated for any reason, this Lock-Up Agreement will automatically terminate, and the undersigned shall be released from all of his, her or its obligations under this Lock-Up Agreement. The undersigned understands that Public Company is proceeding with the transactions contemplated by the Merger Agreement in reliance upon this Lock-Up Agreement. This Lock-Up Agreement will automatically terminate, and the undersigned will be released from all of his, her or its obligations hereunder, upon the date that is six (6) months after the date of the Merger Agreement in the event that transactions contemplated by the Merger Agreement have not been consummated by such date.

Any and all remedies herein expressly conferred upon Public Company will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity, and the exercise by Public Company of any one remedy will not preclude the exercise of any other remedy. The undersigned agrees that irreparable damage would occur to Public Company in the event that any provision of this Lock-Up Agreement was not performed in accordance with its specific terms or were otherwise breached. It is accordingly agreed that Public Company shall be entitled to an injunction or injunctions to prevent breaches of this Lock-Up Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which Public Company is entitled at Law or in equity, and the undersigned waives any bond, surety or other security that might be required of Public Company with respect thereto.

In the event that any holder of Public Company’s securities that are subject to a substantially similar agreement entered into by such holder, other than the undersigned, is permitted by Public Company to sell or otherwise transfer or dispose of shares of Public Company Common Stock for value other than as permitted by this or a substantially similar agreement entered into by such holder, the same percentage of shares of Public Company Common Stock held by the undersigned on the date of such release or waiver as the percentage of the total number of outstanding shares of Public Company Common Stock held by such holder on the date of such release or waiver that are subject of such release or waiver shall be immediately and fully released on the same terms from any remaining restrictions set forth herein (the “Pro-Rata Release”); provided, however, that such Pro-Rata Release shall not be applied unless and until permission has been granted by Public Company to an equity holder or equity holders to sell or otherwise transfer or dispose of all or a portion of such equity holders shares of Public Company Common Stock in an aggregate amount in excess of 1% of the number of shares of Public Company Common Stock originally subject to a substantially similar agreement. The Public Company shall notify the undersigned within two (2) business days prior to the effective date of a release of any holder of Public Company Common Stock of such holder’s obligations under a lock-up or substantially similar agreement that gives rise to a Pro-Rata Release.

Upon the release of any of the Undersigned’s Shares from this Lock-Up Agreement, Public Company will cooperate with the undersigned to facilitate the timely preparation and delivery of certificates representing the Undersigned Shares without the restrictive legend above or the withdrawal of any stop transfer instructions by virtue of this Lock-Up Agreement.

This Lock-Up Agreement and any claim, controversy or dispute arising under or related to this Lock-Up Agreement shall be governed by and construed in accordance with the Laws of the state of Delaware, without regard to the conflict of Laws principles thereof.

This Lock-Up Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Lock-Up Agreement (in counterparts or otherwise) by Public Company and the undersigned by facsimile or electronic transmission in .pdf format shall be sufficient to bind such parties to the terms and conditions of this Lock-Up Agreement.
