Further, the Issuer’s failure to timely provide such advance notice shall give rise to an immediate Forbearance Default, without any requirement of the Requisite Forbearing Noteholders to provide notice thereof.”

The Consenting Noteholders hereby consent to the extension of the date “July 27, 2021” set forth in the first sentence of each of Section 6.01(a) and Section 6.01(b) of the Priming Facility Credit Agreement to August 3, 2021 (the “PTL Extension”), and each reference to the “Priming Facility Credit Agreement” in the Forbearance Agreement shall mean the Priming Facility Credit Agreement as amended by the PTL Extension (and any prior amendments).

This Amendment and all other agreements and documents executed and/or delivered in connection herewith have been prepared through the joint efforts of all of the Parties hereto.

If any provision of this Amendment is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of the Forbearance Agreement, as amended, shall not be affected or impaired thereby and (b) the Parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a

provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Time is of the essence in the performance of the obligations of the Parties hereunder and with respect to all conditions to be satisfied by such Parties.

Section headings in this Amendment are included herein for convenience of reference only and shall not constitute part of this Amendment for any other purpose.
