Form of Letter Agreement Relating to Exchange of Common Stock for Series A Preferred Stock

Exchange. From and after the date hereof, each of the Investors and the Company shall use their reasonable best efforts to, by the date of the closing of the Offering (the “Closing Date”) or, if not accomplished by the Closing Date, as soon as practicable (and in any event within thirty (30) days) thereafter, and contingent upon the closing of the Offering, (i) negotiate and mutually agree to a Series A Common Stock Equivalent Convertible Preferred Stock Certificate of Designation, Preferences and Rights on substantially the terms and conditions set forth in the summary of terms attached hereto as Exhibit A (the “Series A Certificate of Designation” and the shares of capital stock issuable thereunder, “Series A Preferred Stock”), (ii) upon agreement thereof, file the Series A Certificate of Designation with the Secretary of State of the State of Delaware, (iii) negotiate and enter into an agreement (the “Exchange Agreement”) to be entered into between the Company and each of the Investors providing for the exchange of a number of shares of Common Stock beneficially owned by each of the Investors (the “Exchange Shares”), allocated as determined by the Investors, such that the Investors and their affiliates, collectively, beneficially own 9.5% of the outstanding Common Stock as of the date of the closing of such exchange (including, for avoidance of doubt, any shares either Investor acquires in the Offering), for shares of Series A Preferred Stock that are convertible into a number of shares of Common Stock equal to the number of Exchange Shares (subject to the blocker/beneficial ownership limitation set forth in the summary of terms attached hereto as Exhibit A), and (iv) consummate the transactions contemplated by the Exchange Agreement (the “Exchange”). The Company acknowledges and agrees that (i) for purposes of Rule 144 under the Securities Act, each Investor’s holding period for the shares of Series A Preferred Stock issued to it in the Exchange, and any shares of Common Stock issued upon the conversion thereof, shall be deemed to have commenced on the date such Investor acquired such Investor’s Exchange Shares from the Company or an affiliate of the Company (or such earlier date as may be permitted pursuant to Rule 144 under the Securities Act); (ii) the consummation of the Exchange, the issuance of shares of Series A Preferred Stock pursuant to the Exchange and the issuance of shares of Common Stock upon the conversion of the Series A Preferred Stock in full shall not require the approval of stockholders under the Company’s Certificate of Incorporation or Bylaws, the Delaware General Corporation Law, Nasdaq listing rules or otherwise; and (iii) the Exchange and the direct and indirect issuance (or deemed issuance) to the Investors and affiliates thereof of shares of Series A Preferred Stock and shares of Common Stock issuable upon the conversion of the Series A Preferred Stock shall be approved by the Company’s board of directors for purposes of Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Exchange Agreement will provide for the irrevocable surrender of each Investor’s voting rights with respect to the Exchange Shares (including its voting rights in respect of the Company’s annual meeting of stockholders). The Company shall use its reasonable best efforts not to fix a record date for any meeting of its stockholders with respect to which a record date has not already been set until the Exchange has become effective, unless the Exchange shall not have become effective as a result of an Investor’s willful breach of this Letter Agreement (the “Letter Agreement”).
