(b) If no Notice of Withdrawal is given by Lender pursuant to the Security Agreement and the Case is timely initiated by Borrower, but Lender shall thereafter default in the performance of its obligations with respect to the DIP Loan or the APA, then the principal amount hereof, together with interest accruing thereon, shall be due and payable in full on December 31, 2012. Notwithstanding the foregoing, if an Event of Default set forth in subsections (a) through (e) of Section 5.1 of the Security Agreement shall occur following Lender's default in the performance of its obligations with respect to the DIP Loan or the APA , then the principal amount hereof, together with interest accruing thereon, shall be due and payable upon such Event of Default; provided, however, that for purposes of this sentence Borrower's failure to perform the covenants set forth in Sections 4.9 or 4.10 of the Security Agreement shall not be deemed an Event of Default.

(c) If no Notice of Withdrawal is given by Lender pursuant to the Security Agreement and Lender shall otherwise be in compliance with its obligations with respect to the DIP Loan and the APA (to the extent then applicable), then the principal amount hereof, together with interest accruing thereon, shall be due and payable in full on the earlier of:

(i) The date upon which the DIP Loan is approved by the Bankruptcy Court on an interim basis and funding thereof is consummated; or

(ii) The date upon which debtor-in-possession financing from a source other than Lender is approved by the Bankruptcy Court on an interim basis and funding thereof is consummated; or

(iii) The date that is fifteen (15) days after initiation of the Case unless, on or before such date (x) an interim order approving debtor-in-possession financing under item (i) or item (ii) above has been entered by the Bankruptcy Court, and (y) such approved debtor-in-possession financing specifically provides for repayment of the Bridge Loan; or

(iv) The date that is three (3) days after the entry of an interim order approving debtor-in-possession financing under item (iii) above unless, on or before such date, the Bridge Loan has been paid in full from proceeds of such approved financing; or

(d) The outstanding principal balance hereof may be prepaid by Borrower at any time and from time to time, in whole or in part, without premium or penalty. All payments made hereunder shall first be applied to accrued and unpaid interest, with any balance remaining then being applied in reduction of principal.

5. Default and Acceleration. Upon the occurrence of any Event of Default, this Bridge Loan Note and all other Obligations of Borrower to Lender under the Bridge Loan Documents shall be subject to acceleration in accordance with the terms of the Security Agreement and become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby waived by Borrower.
