CERTAIN COVENANTS

1.1 Lock-Up.

(a) Except as contemplated by the Acquisition Agreement, Stockholder hereby covenants and agrees that at any time prior to the Closing Date, Stockholder will not (i) directly or indirectly, sell, transfer, assign, pledge, hypothecate, tender, encumber or otherwise dispose of or limit its right to vote in any manner any of the Securities, or agree to do any of the foregoing, or (ii) take any action which would have the effect of preventing or disabling Stockholder from performing its obligations under this Agreement.

(b) Notwithstanding the provisions of Section 1.1(a), Stockholder may transfer any or all of the Securities to Stockholder’s spouse, ancestors, descendants or any trust for any of their benefits or to a charitable trust; provided, however, that in any such case, prior to and as a condition to the effectiveness of such transfer, (i) each person to which any of such Securities or any interest in any of such Securities is or may be transferred (A) shall have executed and delivered to Arrow a counterpart to this Agreement pursuant to which such person shall be bound by all of the terms and provisions of this Agreement, and (B) shall have agreed in writing with Arrow to hold such Securities or interest in such Securities subject to all of the terms and provisions of this Agreement, and (ii) this Agreement shall be the legal, valid and binding agreement of such person, enforceable against such person in accordance with its terms.

Once transferred in accordance with this Section 1.1(c), the Transferrable Shares, and the recipients thereof, shall not be bound by any provisions of this Agreement.

Arrow hereby acknowledges that the proxy granted hereby shall not be effective for any other purpose. The parties acknowledge and agree that neither Arrow, nor Arrow’s successors, assigns, subsidiaries, divisions, employees, officers, directors, stockholders, agents and affiliates shall owe any duty to, whether in law or otherwise, or incur any liability of any kind whatsoever, including without limitation, with respect to any and all claims, losses, demands, causes of action, costs, expenses (including reasonable attorney’s fees), and compensation of any kind or nature whatsoever to Stockholder in connection with or as a result of any voting by officers of Arrow of the Securities subject to the irrevocable proxy hereby granted to Arrow at any annual, special or other meeting or action or the execution of any consent of the stockholders of the Company for the purpose set forth herein. The parties acknowledge and agree that neither Stockholder nor Stockholder’s successors, assigns and affiliates shall owe any duty to, whether in law or otherwise, or incur any liability of any kind whatsoever, including without limitation, with respect to any and all claims, losses, demands, causes of action, costs, expenses (including reasonable attorney’s fees), and compensation of any kind or nature whatsoever to Arrow in connection with or as a result of any voting by officers of Arrow of the Securities subject to the irrevocable proxy hereby granted to Arrow at any annual, special or other meeting or action or the execution of any consent of the stockholders of the Company for the purpose set forth herein.

(b) The irrevocable proxy established in Section 1.5(a) shall not be terminated by any act of Stockholder or by operation of law, whether by the death or incapacity of Stockholder or by the occurrence of any other event or events (including, without limiting the foregoing, the termination of any trust or estate for which Stockholder is acting as a fiduciary or fiduciaries or the dissolution or liquidation of any corporation or partnership).

REPRESENTATIONS AND WARRANTIES OF STOCKHOLDER

Stockholder hereby represents and warrants to Arrow, as of the date hereof, that:

2.1 Ownership.

(a) Except for the Pledged Shares, Stockholder holds of record or beneficially the Securities, and any Securities acquired after the date hereof will be held, free and clear of all liabilities, claims, liens, options, proxies, charges, participations and encumbrances of any kind or character whatsoever, other than those arising under the securities laws or under the Company’s governance documents (collectively, “Liens”). For the avoidance of doubt, the Commercial Pledge Agreement by and between the Stockholder and JP Morgan dated May 6, 2009 has been terminated and none of the Securities are subject to any lien pursuant thereto.

(b) Schedule I hereto lists the exact location of the Securities (including, if applicable, information of the accounts in or to which each of the Securities is held, credited or located).

2.2 Authorization. Stockholder has (and with respect to the Securities acquired after the date hereof, will have) all requisite power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby and has sole voting power and sole power of disposition, with respect to the Securities with no restrictions on its voting rights or rights of disposition pertaining thereto, except as set forth in the Securities or pursuant to applicable community property Laws. Stockholder has duly executed and delivered this Agreement and this Agreement is a legal, valid and binding agreement of Stockholder,

4

enforceable against Stockholder in accordance with its terms, except to the extent enforceability may be limited by the effect of applicable bankruptcy, reorganization, insolvency, moratorium or other Laws affecting the enforcement of creditors’ rights generally and the effect of general principles of equity, regardless of whether such enforceability is considered in a proceeding at Law or in equity. If the Stockholder is married and the Securities constitute community property, this Agreement has been duly authorized, executed and delivered by the Stockholder’s spouse, and this Agreement is a legal, valid and binding agreement of the Stockholder’s spouse, enforceable against the Stockholder’s spouse in accordance with its terms, except to the extent enforceability may be limited by the effect of applicable bankruptcy, reorganization, insolvency, moratorium or other Laws affecting the enforcement of creditors’ rights generally and the effect of general principles of equity, regardless of whether such enforceability is considered in a proceeding at Law or in equity.

2.3 No Violation. Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (a) require Stockholder to file or register with, or obtain any 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 other than a Schedule 13G or Schedule 13D and any other filings with the SEC that may be required pursuant to the Exchange Act or with the NASDAQ Global Market, or (b) violate, or cause a breach of or default under, or conflict with any contract, agreement or understanding, any Law binding upon 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 Stockholder’s ability to satisfy its obligations under this Agreement. As of the date hereof, no proceedings are pending which, if adversely determined, will have an adverse effect on Stockholder’s ability to vote or dispose of any of the Securities.

2.4 Stockholder Has Adequate Information. Stockholder is a sophisticated seller and has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of an asset sale transaction and making an informed decision with respect thereto. Stockholder has adequate information concerning the business and financial condition of the Company to make an informed decision regarding the asset sale transaction and has independently and without reliance upon Arrow and based on such information as Stockholder has deemed appropriate, made its own analysis and decision to enter into this Agreement. Stockholder acknowledges that Arrow has not made and does not make any representation or warranty, whether express or implied, of any kind or character with respect to the subject matter of this Agreement except as expressly set forth in this Agreement and the Acquisition Agreement. Stockholder acknowledges that the agreements contained herein with respect to the Securities held by Stockholder are irrevocable (prior to the Closing Date), and that Stockholder shall have no recourse against Arrow, except with respect to breaches of representations, warranties, covenants and agreements expressly set forth in this Agreement and the Acquisition Agreement.

2.5 No Setoff. Stockholder has no liability or obligation related to or in connection with the Securities other than the obligations to Arrow as set forth in this Agreement.
