Upon the occurrence of an Event of Default (as defined in the Indenture), if the Trustee takes control of the Liquidity Reserve Escrow Fund, funds in the Liquidity Reserve Escrow Fund may be used for any purpose, including the payment of debt service on the Senior Bonds, as may be determined by the Trustee or as may be directed by the Holders of a majority in aggregate principal amount of the Senior Bonds Outstanding. (d) When the conditions precedent set forth in Section 4.11(a) and Section 4.11(b) have been satisfied and there are no longer any Senior Bonds then Outstanding, then (i) the Guarantor shall no longer have any obligation to maintain the Reduced Liquidity Reserve Amount in the Liquidity Reserve Escrow Fund held under the Liquidity Reserve Escrow Agreement, (ii) this Agreement and the Liquidity Reserve Escrow Agreement will terminate, and (iii) the balance on deposit in the Liquidity Reserve Escrow Fund shall be returned to Guarantor. (e) The foregoing provision notwithstanding, Section 3.09 of this A&R Completion Guaranty shall survive termination of this Agreement and shall remain in full force and effect until the Bonds are paid in full. Section 4.12 Specific Performance. Guarantor acknowledges and agrees that it may be impossible to measure accurately the damages to the Trustee or the Holders of the Bonds resulting from a breach of Guarantor’s covenant to discharge or perform the Obligations, that such a breach will cause irreparable injury to the Trustee and that the Trustee may not have an adequate remedy at law in respect of such breach. As a consequence, Guarantor agrees that such covenant shall be specifically enforceable against Guarantor. Guarantor hereby waives and agrees not to assert in any action for specific performance of such covenant any defense that specific performance is not an available remedy. Section 4.13 Rights and Protections of Trustee. This A&R Completion Guaranty is for the benefit of the Trustee. The Trustee shall be entitled to all of the same rights, benefits, privileges, immunities, disclaimers, exculpations,
