The Company shall not recognize the transfer of any Shares in violation of the transfer restrictions set forth in this Section 2(b).

(a) In any annual, special or adjourned meeting of the stockholders of the Company, and in every written consent in lieu of any such meeting, at which the transactions contemplated by the Purchase Agreement are presented to the Company's stockholders for approval, each Stockholder agrees that it will vote, by proxy or otherwise, its Shares (i) in favor of the transactions contemplated by the Purchase

Agreement and any matter that would reasonably be expected to facilitate such transactions, and (ii) against approval of any proposal made in opposition to the transactions contemplated by the Purchase Agreement. Each Stockholder shall retain at all times the right to vote its Shares in its sole discretion and without any other limitation on those matters other than those set forth in clauses (i) and (ii) of this Section 2(a) that are at any time or from time to time presented for consideration to the Company's stockholders generally.

(b) Notwithstanding the foregoing, nothing in this Agreement shall limit or restrict a Stockholder from acting in such Stockholder's capacity as a director or officer of the Company, to the extent applicable, it being understood that this Agreement shall apply to a Stockholder solely in such Stockholder's capacity as a stockholder of the Company.

(c) In the event that a meeting of the stockholders of the Company is held, each Stockholder shall, or shall cause the holder of record on any applicable record date to, appear at such meeting or otherwise cause such Stockholder's Shares to be counted as present thereat for purposes of establishing a quorum.

(d)  Irrevocable Proxy.

(a) Such Stockholder is the legal or beneficial owner of, and has the power to vote that number of issued and outstanding Shares set forth on the signature page hereto.

(b) Such Stockholder has all requisite power, legal capacity and authority to enter into this Agreement. This Agreement has been duly executed and delivered by Stockholder and, assuming the due authorization, execution and delivery of this Agreement by the Company, constitutes a valid and binding obligation of Stockholder, enforceable against Stockholder in accordance with its terms, except as limited by (a) applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of general application affecting enforcement of creditors' rights generally, and (b) laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

(c) The execution, delivery and performance of this Agreement by such Stockholder will not (i) conflict with, require a consent, waiver or approval under, or result in a breach of or default under, any of the terms of any agreement to which Stockholder is a party or by which any of such Stockholder's assets are bound or (ii) violate any order, writ, injunction, decree, judgment or any applicable law applicable to such Stockholder or any of its assets, except for any such conflict, violation or any failure to obtain such consent, waiver or approval that would not result in such Stockholder being able to perform its obligations under this Agreement.

(d) Such Stockholder agrees that it will not, in its capacity as a stockholder of the Company, bring, commence, institute, maintain, prosecute or voluntarily aid any action, claim, suit or cause of action, in law or in equity, in any court or before any governmental entity, which (i) challenges the validity of or seeks to enjoin the operation of any provision of this Agreement or (ii) alleges that the execution and delivery of this Agreement by such Stockholder, or the approval of the Purchase Agreement by the Company's Board of Directors (the "Board"), breaches any fiduciary duty of the Board or any member thereof.

(e) Such Stockholder shall not, directly or indirectly, take any action that would make any representation or warranty contained herein untrue or incorrect in any material respects or in any way have the effect of restricting, limiting, interfering with, preventing or disabling such Stockholder from performing his, her or its obligations in any material respects under this Agreement.

All notices, requests, and other communications hereunder shall be in writing and will be deemed to have been duly given and received (a) when personally delivered, (b) when sent by facsimile or email upon confirmation of receipt, (c) one business day after the day on which the same has been delivered prepaid to a nationally recognized courier service, or (d) five business days after the deposit in the United States mail, registered or certified, return receipt requested, postage prepaid, in each case addressed, as to the Company, to:

The words "include," "includes" and "including" when used herein shall be deemed in each case to be followed by the words "without limitation." The phrases "the date of this Agreement," "the date hereof," and terms of similar import, unless the context otherwise requires, shall be deemed to refer to the date first above written. Unless the context of this Agreement otherwise requires: (i) words of any gender include each other gender; (ii) words using the singular or plural number also include the plural or singular number, respectively; and (iii) the terms "hereof," "herein," "hereunder" and derivative or similar words refer to this entire Agreement.

The failure of either party hereto to exercise any right, power or remedy provided under this Agreement or otherwise available in respect of this Agreement at law or in equity, or to insist upon compliance by any other party with its obligation under this Agreement, and any custom or practice of the parties at variance with the terms of this Agreement, shall not constitute a waiver by such party of such party's right to exercise any such or other right, power or remedy or to demand such compliance.

(d)  Rules of Construction. The parties hereto hereby waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

(e)  Specific Performance; Injunctive Relief. The parties hereto agree that the Company 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 any Stockholder set forth herein. Therefore, it is agreed that, in addition to

any other remedies that may be available to the Company upon any such violation of this Agreement, the Company and the Investors shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means available to the Company or the

Investors at law or in equity and each Stockholder hereby waives any and all defenses which could exist in its favor in connection with such enforcement and waives any requirement for the security or posting of any bond in connection with such enforcement.

(f)  Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same instrument and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties hereto; it being understood that all parties need not sign the same counterpart.

(g)  Entire Agreement; Nonassignability; Parties in Interest; Death or Incapacity. This Agreement and the documents and instruments and other agreements specifically referred to herein or delivered pursuant hereto (i) constitute an inducement and condition to the Investors entering into the Purchase Agreement, (ii) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and (iii) are not intended to confer, and shall not be construed as conferring, upon any person other than the parties hereto any rights or remedies hereunder. Neither this Agreement nor any of the rights, interests, or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise, by each Stockholder without the prior written consent of the Company, and any such assignment or delegation that is not consented to shall be null and void. This Agreement, together with any rights, interests or obligations of the Company hereunder, may be assigned or delegated in whole or in part by the Company to any affiliate of the Company without the consent of or any action by Stockholder upon notice by the Company to Stockholder as herein provided. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective permitted successors and assigns.

(i)  Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and the application of such provision to other persons or circumstances shall be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto further agree to use their commercially reasonable efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

(j)  Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party shall be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy shall not preclude the exercise of any other remedy.

(k)  Governing Law; Consent to Jurisdiction. This Agreement, and the provisions, rights, obligations, and conditions set forth herein, and the legal relations between the parties hereto, including all disputes and claims, whether arising in contract, tort, or under statute, shall be governed by and construed in accordance with the laws of the State of New York without giving effect to its conflict of law provisions.
