Subject to compliance with the foregoing sentence, if any collateral securing the obligations under the Existing Credit Agreements or any Replacement Credit Agreement is released or the Lien thereon is otherwise terminated, unless such Lien is securing any other Existing Credit Agreement or Replacement Credit Agreement, such Lien securing this Lease Agreement shall automatically be released to the same extent, and Lessors and the trustee shall be authorized to and shall promptly execute and deliver any documents requested by Lessee or the relevant Guarantor to evidence such termination. The Lessee or T-Mobile USA shall provide written notice of any such release to the trustee and “control party” under any Lessor Financing within two Business Days of following the effectiveness of such release.
