3. 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 KBL. In furtherance of the foregoing, the undersigned agrees that KBL 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. KBL 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 KBL 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.

4. 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.

5. The undersigned acknowledges and agrees that the Company is and shall be a third party beneficiary of this Lock-Up Agreement, including, without limitation, the right to provide written consent and waiver prior to the Closing, and shall be entitled to enforce the terms and provisions of this Lock-Up Agreement to the same extent as if it was initially a party hereto.

6. In the event that any holder of KBL Common Stock or securities convertible into or exercisable or exchangeable for KBL Common Stock that is subject to a substantially similar letter agreement entered into by such holder, other than KBL or the undersigned, is permitted by KBL to sell or otherwise transfer or dispose of shares of KBL Common Stock or securities convertible into or exercisable or exchangeable for KBL Common Stock for value other than as permitted by this Lock-Up Agreement or a substantially similar letter agreement entered into by such holder, the same percentage of shares of KBL Common Stock or securities convertible into or exercisable or exchangeable for KBL Common Stock held by the undersigned shall be immediately and fully released on the same terms from any remaining restrictions set forth herein.

7. The undersigned understands that if the Business Combination Agreement is terminated for any reason, or if the Merger is not consummated by ____________, the undersigned shall automatically be released from all restrictions and obligations under this Lock-Up Agreement. The undersigned understands that KBL and the Company are proceeding with the Contemplated Transactions in reliance upon this Lock-Up Agreement.

8. Any and all remedies herein expressly conferred upon KBL will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity, and the exercise by KBL of any one remedy will not preclude the exercise of any other remedy. The undersigned agrees that irreparable damage would occur to KBL in the event that any provision of this Lock-Up Agreement were not performed in accordance with its specific terms or were otherwise breached. It is accordingly agreed that KBL 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 KBL is entitled at law or in equity, and the undersigned waives any bond, surety or other security that might be required of KBL with respect thereto.

10. 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 KBL 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.
