The Company shall file with the Trustee notice in accordance with Section 105 of the Base Indenture and provide notice to the Holders (through the inclusion of information with respect any of the actions described in the following clauses (x) and (y) in any report filed by the Company pursuant Section 13 or 15(d) of the Exchange Act or through notice otherwise provided to the Holders) of (x) any revocation of the designation of the Securities as Designated Senior Debt or “Other DS Debt” in accordance with the Security Agency Agreement or (y) any amendment, supplement, restatement, amendment and restatement, other modification or replacement of the Security Agency Agreement or any other Security Document;

Upon the receipt of Recoveries or any other cash, securities or other property under the Security Agency Agreement or any other Security Document, including the receipt of any proceeds from the realization or foreclosure of the Pledged Collateral pursuant to any Security Document, such cash, securities or other property shall be held by the Trustee in trust and be applied by the Trustee in accordance with Section 506 of the Indenture.

Section 3.3. Opinion of Counsel; Certificates of the Company. The Company shall furnish to the Trustee (i) promptly after the execution and delivery of this Second Supplemental Indenture, an Opinion of Counsel required by TIA Section 314(b)(1) and (ii) annually within 120 days after the end of the Company’s fiscal year, an Opinion of Counsel in accordance with TIA Section 314(b)(2).

Section 3.4. Trust Indenture Act Requirements. Notwithstanding Section 3.3, the release of any Pledged Collateral from the Security Liens or the release of, in whole or in part, the Security Liens created by any of the Security Documents (including any release of the Security Liens as a result of the Company revoking the designation of the Securities, or any series of Securities, as “Other DS Debt” after disclosing such revocation as provided in the Security Agency Agreement) will not be deemed to impair or release the Security Liens in contravention of the provisions hereof if and to the extent the Pledged Collateral or the Security Liens are released pursuant to the terms of the Security Agency Agreement or the applicable Security Document. Each of the Holders of the Securities acknowledges that a release of Pledged Collateral or Security Liens in accordance with the terms of the Security Agency Agreement, the Security Documents and this Indenture will not be deemed for any purpose to be an impairment of the Security Documents or otherwise contrary to the terms of this Indenture.
