Upon payment for the Shares in accordance with this Agreement, the Stockholder will convey the Shares to the Company free and clear of all liens, pledges, security interests, charges, contractual obligations, claims or encumbrances of any kind (other than those that may be created by the Company). Neither the execution and delivery of this Agreement, nor the consummation of any of the transactions contemplated hereby nor compliance with or fulfillment of the terms, conditions and provisions hereof, will result in the creation of any mortgage, pledge, lien, security interest, encumbrance, contractual obligation or charge upon the Shares (other than those created by the Company). The Stockholder has not granted any options of any sort with respect to the Shares or any right to acquire the Shares or any interest therein other than under this Agreement.

4.4 Disclosure of Information. The Stockholder has received all the information that it, with the advice of its financial advisors, considers necessary or appropriate for deciding whether the Stockholder should sell the Shares to the Company pursuant to this Agreement. The Stockholder has all information or access to information regarding the Company and its business, including financial and operating data for the quarter ended December 31, 2009 and the full 2009 fiscal year and information relating to the Company’s plans and prospects, and including the Company’s public filings made pursuant to federal securities laws, that it believes is necessary to make an informed and knowledgeable decision with regard to the transactions contemplated hereby. The Stockholder acknowledges (i) that neither the Company, nor any of the Company’s Related Parties (as defined below), has made any representation or warranty, express or implied, except as set forth herein, regarding any aspect of the sale and purchase of the Shares, the operation or financial condition of the Company or the value of the Shares, (ii) that the Stockholder is not relying upon the Company or any of the Company’s Related Parties in making its decision to sell the Shares to the Company pursuant to this Agreement, (iii) that the Company is relying upon the truth of the representations and warranties in this Section 4 in connection with its purchase of the Shares hereunder. For purposes of this Agreement, “Related Parties” shall mean the Company’s current and former directors, officers, partners, employees, attorneys, agents, successors, assigns, current and former stockholders (including current and former limited partners, general partners and management companies), owners, representatives, predecessors, parents, affiliates, associates and subsidiaries.

The Stockholder expressly acknowledges that any such Corporate Event may result in the payment by the Company or a third party of assets, funds or other proceeds to the Company’s stockholders in a manner such that the value attributed to the Company’s Series B Preferred Stock or Common Stock in such Corporate Event (either in an aggregate amount or on a per share basis) may be greater than the purchase price paid pursuant to in this Agreement.

4.6 Tax Consequences. The Stockholder has had an opportunity to review the federal, state and local tax consequences of the sale of the Shares to the Company and the transactions contemplated by this Agreement with his own tax advisors. The Stockholder is relying solely on such advisors for tax advice and not on any statements or representations of the Company or any of its respective Related Parties. The Stockholder (and not the Company) shall be responsible for its own tax liabilities that may arise as a result of the transactions contemplated by this Agreement.

5.4 Survival. The representations, warranties, covenants and agreements made herein shall survive the Closing.

5.5 Severability. If any provision of this Agreement shall be invalid or unenforceable, such invalidity or unenforceability shall not affect the validity and enforceability of the remaining provisions of this Agreement.

5.6 Successors and Assigns. No party may assign any of its rights or obligations under this Agreement without the prior written consent to the other party hereto. Subject to the preceding sentence, this Agreement will apply to, be binding in all respects upon, and inure to the benefit of the successors and permitted assigns of the parties. Nothing expressed or referred to in this Agreement will be construed to give any person or entity other than the parties to this Agreement (and their permitted successors and assigns) any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement. This Agreement and all of its provisions and conditions are for the sole and exclusive benefit of the parties to this Agreement and their successors and permitted assigns. Any attempted assignment in violation of this Agreement shall be null and void ab initio.

5.7 Entire Agreement. This Agreement constitutes the entire agreement of the parties and supersedes all prior agreements and understandings, whether written or oral, between the parties with respect to the subject matter of this Agreement.

5.8 Waivers and Amendments. This Agreement may be amended, modified, superseded or terminated, and the terms and conditions of this Agreement may be waived, only by a written instrument signed by the Company and the Stockholder or in the case of a waiver, by the party waiving compliance. No delay on the part of any party in exercising any right, power or privilege pursuant to this Agreement shall operate as a waiver thereof, nor shall any waiver on the part of any party of any right, power or privilege pursuant to this Agreement, nor shall any single or partial exercise of any right, power or privilege pursuant to this Agreement, preclude any other or further exercise thereof or the exercise of any other right, power or privilege pursuant to this Agreement. The rights and remedies provided pursuant to this Agreement are cumulative and are not exclusive of any rights or remedies which any party otherwise may have at law or in equity.

5.10 Governing Law. This Agreement shall be governed in all respects by the laws of the State of California without giving effect to principles of conflicts of law that would result in the application of the laws of a different jurisdiction.

5.11 Headings. The headings in this Agreement are for reference purposes only and shall not in any way affect the meaning or interpretation of this Agreement.

5.12 Specific Performance. The parties acknowledge and agree that any breach of the terms of this Agreement would give rise to irreparable harm for which money damages would not be an adequate remedy, and, accordingly, the parties agree that, in addition to any other remedies, each party will be entitled to enforce the terms of this Agreement by a decree of specific performance without the necessity of proving the inadequacy of money damages as a remedy and without the necessity of posting bond.

5.13 Jurisdiction; Service of Process.
