C.

In order to induce Purchasers to make the loan as provided for in the Purchase Agreement, Pledgor has agreed to pledge the Pledged Shares to Purchasers’ Representative (as agent for Purchasers) and to grant Purchasers’ Representative (as agent for Purchasers)  the right to purchase the Pledged Shares in accordance herewith.

Agreement

In consideration of the premises and mutual covenants herein contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.

Pledge.  Pledgor hereby pledges to Purchasers’ Representative (as agent for Purchasers), and grants to Purchasers’ Representative (as agent for Purchasers) a first priority security interest in, the Pledged Shares and the certificates representing the Pledged Shares, as security for payment of the Senior Note.  All certificates evidencing the Pledged Shares shall be delivered to and held by Purchasers’ Representative (as agent for Purchasers) pursuant hereto.  The Pledgor will notify the Company to add a notation to the stock registry book of the Company, containing a notation stating that the Pledged Shares have been pledged in favor of the Purchasers’ Representative, and will cause to be delivered to the Purchasers’ Representative a certificate signed by the Secretary of the board of directors of the Company indicating that such pledge has been registered as provided herein and that the Secretary is aware of the contents of this Agreement.

2.

Defaults and Remedies.  If the Company is in default in making any mandatory payment of principal on the Senior Note, and such default is not cured within 15 days after written notice from Purchasers’ Representative to the Company and Pledgor, Purchasers’ Representative is hereby authorized and empowered to transfer and register in its name or in the name of its nominee the whole or any part of the Pledged Shares, to sell in one or more sales after thirty (30) days' notice of the time and place of any public sale or of the time at which a private sale is to take place (which notice Pledgor agrees is commercially reasonable) the whole or any part of the Pledged Shares and to otherwise act with respect to the Pledged Shares as though Purchasers’ Representative was the outright owner thereof. Any sale shall be made at a public or private sale at Purchasers’ Representative's place of business, or at any place to be named in the notice of sale, either for cash or upon credit or for future delivery at such price as Purchasers’ Representative may deem fair, and Purchasers’ Representative (as agent for Purchasers) may be the purchaser of the whole or any part of the Pledged Shares so sold. Each sale shall be made to the highest bidder, but Purchasers’ Representative reserves the right to reject any and all bids at such sale that, in its discretion, it shall deem inadequate.

3.

Proxy; Voting.  Pledgor hereby irrevocably constitutes and appoints Purchasers’ Representative as the proxy and attorney-in-fact of Pledgor with respect to the Pledged Shares, including the right to vote the Pledged Shares, with full power of substitution to do so. The appointment of Purchasers’ Representative as proxy and attorney-in-fact is coupled with an interest and shall be irrevocable until the termination date. In addition to the right to vote the Pledged Shares, the appointment of Purchasers’ Representative as proxy and attorney-in-fact shall include the right to exercise all other rights, powers, privileges and remedies to which a holder of the Pledged Shares would be entitled (including giving or withholding written consents of stockholders, calling special meetings of stockholders and voting at such meetings). Such proxy shall be effective, automatically and without the necessity of any action (including any transfer of any Pledged Shares on the record books of the Company) by any person.  Notwithstanding the foregoing, Purchasers’ Representative shall not have any duty to exercise any such right or to preserve the same and shall not be liable for any failure to do so or for any delay in doing so.  Notwithstanding the foregoing, Purchasers’ Representative agrees that until the occurrence of an Event of Default under the Senior Note, Purchasers’ Representative shall vote the Pledged Shares in accordance with the provisions of the Voting Agreement dated as of April 15, 2011 among the Company, Pledgor, Purchaser and other stockholders of the Company.

4.

Power of Attorney.  The Pledgor hereby irrevocably appoints the Purchasers’ Representative as the Pledgor’s special attorney-in-fact, with full authority in the place and stead of the Pledgor and in the name of the Pledgor or otherwise, from time to time in the Purchasers’ Representative’s discretion, to take any action and to execute any instrument that the Purchasers’ Representative may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation:
