The Buyer acknowledges and confirms that the Sale Share may be an illiquid investment; and the Buyer has adequate means of providing for the Buyer’s liquidity needs even if the Sale Share are restricted from public trading on any securities exchange. The Buyer is aware of the litigation surrounding the validity of the Rights Agreement and the validity of issuance of the Exchange Shares. The Buyer acknowledges and confirms that (i) the Seller does not make any representation as to the validity of the Rights Agreement and the validity of the issuance of the Exchange Shares and any liability in connection therewith, (ii) the Buyer is buying the Sale Shares “as is,” with no representation from the Seller as to the affairs of viability of the Company, or as to assets, liabilities, or outstanding securities of the Company, except for such representations and warranties of the Seller made under Section 3.6 and Section 4.6.

Section 5.7 Material Nonpublic Information. Neither the Seller nor any of its Affiliates, principals, stockholders, partners, employees and agents (i) has been requested to or has provided the Buyer with any information or advice with respect to the Sale Shares nor is such information or advice necessary or desired, or (ii) has made or makes any representation as to the Company or the credit quality of the Sale Shares. The Buyer acknowledges and understands that (i) the Seller and its Affiliates may possess material nonpublic information regarding the Company not known to the Buyer that may impact the value of the Sale Shares, including, without limitation, (x) information received by principals and employees of the Seller in their capacities as directors, board observers, officers, significant stockholders and/or Affiliates of the Company, (y) information otherwise received from the Company on a confidential basis, and (z) information received on a privileged basis from the attorneys and financial advisers representing the Company and its board of directors (collectively, the “Information”), and that the Seller is not disclosing the Information to the Buyer. The Buyer understands, based on its experience, the disadvantage to which the Buyer is subject due to the disparity of information between the Seller and the Buyer. Notwithstanding such disparity, the Buyer has deemed it appropriate to enter into this Agreement and to consummate the Transactions.

The Buyer is acquiring the Sale Shares for investment for its own account and not with a view toward any resale or distribution of any part thereof except in compliance with the Securities Act. The Buyer does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to any Person with respect to the Sale Shares.
