(b) Authority; Enforcement. The Company has all requisite power and authority to enter into and perform this Agreement and to consummate the transactions contemplated hereby. This Agreement constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to the effect of any applicable bankruptcy, insolvency, reorganization, or moratorium or similar laws affecting the rights of creditors generally and application of general principles of equity. The issuance of the Common Shares hereunder has been duly and validly authorized by all requisite corporate action of the Company and when issued in accordance with this Agreement, the Common Shares will be validly issued, fully paid and non-assessable.

(c) No Conflicts. The execution, delivery and performance of this Agreement by the Company and the consummation by the Company of the transactions contemplated hereby will not (i) violate or conflict with, or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time or both, could become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any material agreement, indenture, patent, license or instrument to which the Company or any of its subsidiaries is a party or (ii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations) applicable to the Company or any of its subsidiaries or by which any property or asset of the Company or any of its subsidiaries is bound or affected.

(d) No Consent or Approval Required. No consent, approval or authorization of, or filing with, any third party, including the Company and any governmental or regulatory authority, is required for the valid authorization, execution and delivery by the Company of this Agreement.

(b) No Conflicts. The execution, delivery and performance of this Agreement by the Stockholders and the consummation by the Stockholders of the transactions contemplated hereby will not (i) violate or conflict with, or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time or both, could become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any material agreement, indenture, patent, license or instrument to which the Stockholders are parties, or (ii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations) applicable to the Stockholders or by which any property or asset of the Stockholders is bound or affected.

Christopher S. Gaffney, a manager of the Stockholders, is a current member of the Company’s Board of Directors.

(d) Access to Information. The Stockholders have had an opportunity to meet with the Company’s management to ask questions and the Stockholders were given full access to all documentation which the Company possesses or can acquire without unreasonable effort or expense that is necessary to verify the accuracy of the information furnished to the Stockholders.

The Exchange Shares are entirely free and clear of any security interests, liens, claims, charges, options, mortgages, debts, conditional sales agreements, encumbrances of any kind, and material defects as to title.

(h) Holding Period. The Stockholders purchased and fully paid for the Exchange Shares, in accordance with Rule 144 of the Securities Act, for a period greater than six (6) months.

4. Affirmative Covenants.

(a) Delivery of Exchange Shares Certificates. Simultaneous with the execution of this Agreement, the Stockholders shall deliver to the Secretary of the Company, as Escrow Agent, any and all certificates and documents, duly endorsed, representing all of the Exchange Shares. Such certificates and documents shall be held in escrow by the Escrow Agent until the Effective Date of this Agreement (which shall be the date that Common Shares certificates are delivered to the Stockholders in exchange for such Exchange Shares). On the Effective Date, the Escrow Agent shall deliver to the Company’s transfer agent instructions (such instructions shall be provided to the Escrow Agent by the Stockholders) whereby the Company’s transfer agent is instructed to deliver the Common Shares to a broker-dealer designated by the Stockholders with restrictive legend. Such Common Shares shall be free and clear of all liens, restrictions, encumbrances, charges, security interests and adverse claims of every kind and character, other than restrictions imposed by federal and state securities laws and this Agreement and shall be legally and validly issued, duly authorized, fully paid and non-assessable.

(b) Further Assurances. The parties agree that they will at any time and from time to time after the Effective Date, upon request of the other party and at such requesting party’s expense, use commercially reasonable efforts to do, execute, acknowledge and deliver or cause to be done, executed, acknowledged and delivered all such further acts, deeds, assignments, transfers, conveyances, powers of attorney and assurances as may be required to carry out the purposes of this Agreement.

5. Miscellaneous.

(a) Amendments. Any provision of this Agreement may, subject to applicable law, be amended only with the written consent of the Company and each of the Stockholders.

(b) Waiver. Neither the failure nor any delay on the part of any party hereto to exercise any right, remedy, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy, power or privilege preclude any other or further exercise of the same or of any other right, remedy, power or privilege, nor shall any waiver of any right, remedy, power or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence. No waiver shall be effective unless it is in writing and is signed by the party asserted to have granted such waiver.

(c) Successors and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties.

(e) Expenses. Each party shall pay all costs and expenses that it incurs with respect to the negotiation, execution, delivery and performance of this Agreement.

(f) Severability.
