4. The parties hereby amend Section 6.11 to delete “If to the Versa Holding Vehicle:” and the accompanying addresses of Versa Capital Management, LLC and Sullivan & Cromwell LLP.

5. Upon the execution of this letter agreement by the parties hereto, Versa hereby agrees that it shall cause Paul Halpern to resign from his position as a director of the Company by submitting to the Board of Directors of the Company (the “Board”) a letter in the form attached hereto as Exhibit A.
