SECTION 2.2. No Violation. Neither the execution and delivery of this Agreement nor the performance of this Agreement by the Stockholder will (a) require the Stockholder to file or register with, or obtain any material permit, authorization, consent or approval of, any governmental agency, authority, administrative or regulatory body, court or other tribunal, foreign or domestic, or any other entity, or (b) violate, or cause a breach of or default under, or conflict with any contract, agreement or understanding, any statute or law, or any judgment, decree, order, regulation or rule of any governmental agency, authority, administrative or regulatory body, court or other tribunal, foreign or domestic, or any other entity or any arbitration award binding upon the Stockholder, except for such violations, breaches, defaults or conflicts which are not, individually or in the aggregate, reasonably likely to have an adverse effect on the Stockholder’s ability to satisfy its obligations under this Agreement. No proceedings are pending which, if adversely determined, will have an adverse effect on the Stockholder’s ability to vote any of the Shares.

SECTION 2.3. Ownership of Shares. The Stockholder has good and marketable title to, and is the sole legal and beneficial owner of the Shares set forth opposite its name on Schedule I hereto, in each case free and clear of all liabilities, claims, liens, options, security interests, proxies, voting trusts, voting agreements, charges, participations and encumbrances of any kind or character whatsoever, except as may be imposed by federal, state or foreign securities laws. The Stockholder has not previously assigned or sold any of the Shares to any third party.

MISCELLANEOUS

SECTION 3.1. Definitions. Terms used but not otherwise defined in this Agreement have the meanings ascribed to such terms in the Securities Purchase Agreement.

SECTION 3.2. Termination. This Agreement shall terminate and be of no further force and effect upon the earlier of (i) the date that the parties hereto have consented to the termination of this Agreement and (ii) immediately following a meeting of the Company’s stockholders at which the Proposal is voted upon by the Company’s stockholders, which meeting is duly called and held for such purpose and at which a quorum was present and acting throughout.

From time to time at the request of the holders of more than 50% of all of the Common Shares held by the Call Investors (the “Majority Call Investors”) and without further consideration, the Stockholder will execute and deliver to the Company and the Call Investors such documents and take such action as the Majority Call Investors may reasonably deem to be necessary or desirable to carry out the provisions hereof.

SECTION 3.4. No Waiver. The failure of any party hereto to exercise any right, power or remedy provided under this agreement or otherwise available in respect hereof at law or in equity, or to insist upon compliance by any other party hereto with its obligations hereunder, or any custom or practice of the parties at variance with the terms hereof shall not constitute a waiver by such party of its right to exercise any such or other right, power or remedy or to demand such compliance.

SECTION 3.5. Specific Performance. The Stockholder acknowledges that the Company and the Call Investors will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of the Stockholder that are contained in this Agreement.

Accordingly, should the Company or any Call Investor institute an action or proceeding seeking specific enforcement of the provisions hereof, the Stockholder hereby waives the claim or defense that the Company or such Call Investor has an adequate remedy at law and hereby agrees not to assert in any such action or proceeding the claim or defense that such a remedy at law exists.
