WHEREAS, Lessee has requested that Lessor provide for an additional early termination option under Schedule 1 and Schedule 3;

WHEREAS, Lessee has requested certain conforming changes to a similar early termination option under Schedule 2 to ensure that each Schedule contains the same Exit Right (as defined below); and

NOW, THEREFORE, in consideration of the mutual premises herein contained and for other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1.Definitions. Capitalized terms used but not otherwise defined herein have the meanings ascribed to such terms in the applicable Lease.

Amendments.

(a).Subject to the terms and conditions of this Amendment, as of the date hereof, Lessee and Lessor hereby agree that notwithstanding anything to the contrary in the Leases or any other Lease Documents, Schedule 1 and Schedule 3 are each amended to insert the following new clause (c) in Section 10 of each such Schedule:

“(c) Notwithstanding anything in the Lease to the contrary, in connection with an Eligible Capital Event, and provided (i) Lessee has paid and Lessor has received all rental and any other payments due under the Lease at or prior to their respective due dates taking into account any allowed grace periods; (ii) no Event of Default shall have occurred and be continuing under the Lease, and (iii) the Early Termination Date has not yet occurred, Lessee shall have the right (the “Exit Right”), upon not less than 10 business days’ prior written notice to Lessor (which notice (an “Exit Notice”) may be contingent, and conditional upon, the successful closing of the Eligible Capital Event if so stated therein), on the date specified by Lessee in the Exit Notice (the “Exit Date”), to purchase all, but not less than all, of the Equipment by paying a lump sum cash payment to Lessor on the Exit Date in an amount equal to (x) the Stipulated Loss Value of the Equipment as of the Exit Date (and without any refund of rent paid on or prior to the Exit Date), plus (y) a fee of

$11,500,000.00 plus (z) all rents, applicable taxes and other amounts then due and owing under the Lease and all transfer taxes (the sum of (x)-(z), the “Exit Price”; such Exit Price a negotiated amount only and expressly for the purpose of this Exit Right and not otherwise intended in any way (nor shall it be deemed) to approximate the value of the Equipment or for any other purpose whatsoever). Upon receipt by Lessor of the Exit Price on the Exit Date as described above, together with any other amounts due and payable under the Lease, all in immediately collectable funds, Lessor shall transfer to Lessee, without recourse or warranty of any kind, express or implied, all of Lessor’s right, title and interest in and to the Equipment on an AS-IS, WHERE-IS basis, except Lessor will be deemed to warrant that the Equipment is free and clear of any liens created by Lessor or any party on its behalf. Lessee shall reimburse Lessor for all taxes, out-of-pocket charges and expenses relating to the sale, registration, use, possession, and operation of the Equipment. Lessor shall provide promptly to Lessee following Lessee’s request (1) wire transfer information, (2) a list of all charges and amounts due and owing by Lessee to Lessor at any relevant date in connection with the foregoing, and (3) such other information and calculations as Lessee may reasonably request in order to permit Lessee to exercise and perform the early termination option described in this Section 10(c). Notwithstanding anything to the contrary contained herein or otherwise, (A) if for any reason Lessee fails to pay the Exit Price and consummate the purchase on the date set forth in any Exit Notice, Lessee shall, promptly upon Lessor’s request therefor, reimburse Lessor for all reasonable,

VP/#68199763.2

documented, out-of-pocket costs, if any, actually incurred by Lessor in connection with such failure, and (B) the Exit Right hereunder may only be exercised and consummated if the “Exit Price” (if any) set forth under each other Schedule issued pursuant to the MLA is also simultaneously received in full by Lessor. “Eligible Capital Event” means one or more public or private capital raises (whether as debt or equity, and regardless of form, including options, warrants, instruments convertible into other securities, and any other form of debt or equity security) resulting in proceeds to Lessee equal to at least the applicable Exit Price

(b).Subject to the terms and conditions of this Amendment, as of the date hereof, Lessee and Lessor hereby agree that notwithstanding anything to the contrary in the Leases or any other Lease Documents, Section 10(b) of Schedule 2 is hereby amended and restated in its entirety to read as follows:

“b. Notwithstanding anything in the Lease to the contrary, in connection with an Eligible Capital Event, and provided (i) Lessee has paid and Lessor has received all rental and any other payments due under the Lease at or prior to their respective due dates taking into account any allowed grace periods; (ii) no Event of Default shall have occurred and be continuing under the Lease, and (iii) the Early Termination Date has not yet occurred, Lessee shall have the right (the “Exit Right”) to, upon not less than 10 business days’ prior written notice to Lessor (which notice (an “Exit Notice”) may be contingent, and conditional upon, the successful closing of the Eligible Capital Event if so stated therein) , purchase on the date specified by Lessee in the Exit Notice (the “Exit Date”) all, but not less than all, of the Equipment by paying a lump sum cash payment to Lessor on the Exit Date in an amount equal the Exit Price (defined below). Upon receipt by Lessor of the Exit Price on the Exit Date as described above, together with any other amounts due and payable under the Lease, all in immediately collectable funds, Lessor shall transfer to Lessee, without recourse or warranty of any kind, express or implied, all of Lessor’s right, title and interest in and to the Equipment on an AS- IS, WHERE-IS basis, except Lessor will be deemed to warrant that the Equipment is free and clear of any liens created by Lessor or any party on its behalf. Lessee shall reimburse Lessor for all taxes, out-of-pocket charges and expenses relating to the sale, registration, use, possession, and operation of the Equipment. Lessor shall provide promptly to Lessee following Lessee’s request (1) wire transfer information, (2) a list of all charges and amounts due and owing by Lessee to Lessor at any relevant date in connection with the foregoing, and (3) such other information and calculations as Lessee may reasonably request in order to permit Lessee to exercise and perform the early termination option described in this Section 10(b).

The parties hereto acknowledge and agree that this Exit Price is a negotiated amount only and expressly for the purpose set forth above and is not otherwise intended by the parties to, nor shall it otherwise be deemed to, approximate the value of the Equipment or for any other purpose whatsoever.

(c).Subject to the terms and conditions of this Amendment, as of the date hereof, Lessee and Lessor hereby agree that notwithstanding anything to the contrary in the Leases or any other Lease Documents, Section 10(c) of Schedule 2 is hereby amended and restated in its entirety to read as follows:

“c. Upon receipt by Lessor of the Early Termination Purchase Price on the Early Termination Date as described in (a) above, together with any other amounts due and payable under the Lease, all in immediately collectable funds, Lessor shall transfer to Lessee all of Lessor’s right, title and interest in and to such Equipment on an “as is,” “where is,” “with all faults” basis, without any warranties or representations of any kind whatsoever by, or recourse to Lessor, except that Lessor will, upon such transfer of the Equipment pursuant to the foregoing, warrant that the Equipment is

(b) the execution, delivery, and performance by Lessee of this Amendment is within the powers and authority of Lessee and has been duly authorized by Lessee; (c) this Amendment constitutes the legal, valid, and binding obligation of Lessee, enforceable against Lessee in accordance with its terms, except to the extent that enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization, or other similar laws affecting the enforcement of creditors’ rights or by the effect of general equitable principles; and (d) no Event of Default has occurred and is continuing, or will result immediately after giving effect to the transactions contemplated by this Amendment.
