In the event that the IPO is not consummated within 14 days of the date the Purchase Price is delivered to GM, GM shall return the Purchase Price to the undersigned, without interest or deduction.

Moreover, the undersigned hereby acknowledges and agrees that he will not (i) offer, sell, contract to sell, pledge, hypothecate, grant any option to purchase or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the undersigned or any affiliate of the undersigned or any person in privity with the undersigned or any affiliate thereof), directly or indirectly, including the participation in the filing of a registration statement with the Securities and Exchange Commission in respect of, (ii) establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission promulgated thereunder, with respect to or (iii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of, or any securities convertible into or exercisable or exchangeable for, or other rights to purchase, whether any such transaction is to be settled by delivery of Common Stock, Sponsors’ Warrants or such other securities, in cash or otherwise, any Sponsors’ Warrants, or publicly announce an intention to effect any such transaction, until after the Corporation has consummated a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more operating businesses or assets (“Business Combination”) meeting the requirements set forth in the Registration Statement; provided, however, that notwithstanding anything to the contrary in this Agreement, the undersigned may, at any time, transfer Sponsors’ Warrants (x) to its members upon a liquidation or to relatives and trusts for estate planning purposes, (y) by virtue of the laws of descent and distribution upon death, or (z) pursuant to a qualified domestic relations order, providing the transferee agrees to be bound by the transfer restrictions and acknowledges that the certificates for such Sponsors’ Warrants shall contain a legend indicating such restriction on transferability.

The Company hereby acknowledges and agrees that the Sponsors’ Warrants will be exercisable on a cashless basis and, in the event the Company calls the Warrants for redemption pursuant to that certain Warrant Agreement to be entered into by the Company and Continental Stock Transfer & Trust Company in connection with the Company’s IPO, shall not be redeemable by the Company so long as such Sponsors’ Warrants are held by the undersigned or his permitted transferees.

The terms of this agreement and the restriction on transfers with respect to the Sponsors’ Warrants may not be amended without the prior written consent of Citigroup.
