 CONFIDENTIAL TREATMENT REQUESTED 

 

 THEREFORE, in consideration of the premises and the covenants and agreements contained
herein, the parties hereto hereby agree that on the Restatement Date (as defined below), the Existing Master Lease Agreement shall be amended and restated in its entirety as follows: 

 

	1.	Interpretation 

  

	1.1	The headings do not affect the interpretation of this Agreement and the Schedules form part of this Agreement. 

 

	1.2	In this Agreement, all capitalized terms shall have the meanings set forth herein or in Schedule 1 to this Agreement. The definitions of terms herein shall apply
equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include”, “includes” and
“including” shall be deemed to be followed by the phrase “without limitation.” The word “will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise
(a) the words “herein”, “hereof” and “hereunder”, and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision hereof and (b) all references
herein to clauses and Schedules shall be construed to refer to clauses and Schedules to this Agreement. The term “including” when used in any Operative Document means “including without limitation” except when used in the
computation of time periods. 

  

	2.	General Obligations 

  

	2.1	During the Lease Commitment Period, Lessor and Lessee agree, so long as no Default exists and is then continuing or would result therefrom, to enter into Leases from
time to time whereby Lessor shall make available to Lessee under each Lease the Metal Amount contained in one Unit for use at Lessee’s Facilities, provided that the total Metal Amounts in all outstanding Leases shall not exceed the
Maximum Lease Amount. 

  

	2.2	A Lease executed by each of Lessor and Lessee substantially in the form of Schedule 2 incorporating the Lease details as set out in clause 3 shall be exchanged between
Lessor and Lessee in respect of the Metal Amount in each Unit. 

  

	2.3	Any renewal or amendments to a Lease shall only be effective if confirmed in writing between Lessor and Lessee. 

 

	2.4	[Reserved]. 

  

	2.5	This Agreement, each Lease, the Guarantee Documents, and all amendments and renewals thereto and thereof shall constitute a single contract. 

 

	2.6	Lessee shall settle each Lease on the Termination Date or Early Termination Date applicable to that Lease, as determined in accordance with clause 7.

  

	2.7	 Provided that no Lease Term shall have a Lease Expiration Date later than the end of the Lease Commitment Period, Lessee shall, so long as no Default
exists and is then continuing or would result therefrom and subject to the terms hereof, be entitled to renew any Lease; provided that upon any such renewal, Lessee shall have been deemed to represent and warrant to Lessor that, as of such
date, each of the representations and 

  
 2 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	
warranties in this Agreement, other than clause 9.2(k), is true and correct in all material respects as of such date (except (i) to the extent that it expressly relates to another date, in
which case it is true and correct in all material respects as of such other date and (ii) any representation and warranty that itself is qualified as to “materiality” or “Material Adverse Effect” shall be true and correct in
all respects). Notwithstanding the previous sentence, no renewal shall be effective if, at the time of such renewal, a Default exists and is then continuing or would result therefrom and no Lease shall be renewed if the effect of any renewal would
be to extend the Lease Expiration Date for that Lease to a date falling (x) less than one month following the original Lease Expiration Date for that Lease or (y) more than twelve months after the original Commencement Date of that Lease.

  

	2.8	Lessee shall not sublease any of the Metal or the Units to any other person or allow the Metal or Units to be removed from the Facilities or permit the Metals or Units
to be used by anyone other than Lessee’s employees, except as otherwise permitted in connection with Change-Outs and Refabrications pursuant to clause 6 or until the Metals or Units are delivered to Lessor or title is transferred to Lessee in
accordance with clause 7.2. 

  

	2.9	[Reserved]. 

  

	2.10	[Reserved]. 

  

	2.11	Lessee represents, warrants and agrees that it does not have, and by execution of this Agreement or any Lease and/or any payment or performance hereunder or thereunder
it shall not have or obtain, any title to the Metals, the Non-Leased Lessor Rhodium or the Units, nor any property right or interest, legal or equitable, therein, except its rights as expressly set forth hereunder or thereunder as a lessee of the
Metals subject to the terms hereof and thereof. 

  

	2.12	Lessor shall not be liable in any way for the maintenance or performance of the Metals or the Units. 

 

	3.	Lease Details 

  

	3.1	During the Lease Commitment Period, Lessee may request Lessor enter into a new Lease or renew an existing Lease (for purposes of a renewal, by sending a request for
such in writing to Lessor in accordance with clause 2.7 hereof). 

  

	3.2	Where Lessor and Lessee agree to enter into a new Lease or renew an existing Lease each new or renewed Lease shall be confirmed in writing by Lessee and Lessor and

Account, (ii) any Non-Leased Lessor Rhodium or (iii) any Non-Lessor Metal. 

  

	3.4	On and after the Restatement Date, in the event of any inconsistency between the terms of this Agreement and the terms of any Lease or amendment thereto (including
without limitation Leases entered into prior to the Restatement Date and still in effect as of the Restatement Date) that has been executed by both parties, the terms of this Agreement shall prevail. 

 

	4.	Lease Rent 

  

	4.1	Lessee shall pay to Lessor on each Payment Date monthly rent (“Lease Rent”) for each Metal Amount that is the subject of a Lease calculated (on the
basis of a 360-day year and actual days per month) by multiplying: 

 (Metal Amount) X (Value of the Metal) X
(Lease Rate Index + Margin) X (actual days/360) 
 Where: 

the “Value” means the Benchmark Value for the relevant Metal on the day that is two Business Days prior to the
Commencement Date of the relevant Lease; 
 the “Lease Rate Index” means, in the case of Platinum, the offered
rate for Platinum as published two Business Days prior to the commencement of the applicable Lease Term on Deutsche Bank’s Daily Precious Metal Rates Sheet “DBRates.xls”; and in the case of Rhodium, the offered rate for Rhodium
as published two Business Days prior to the commencement of the applicable Lease Term on Deutsche Bank’s Daily Precious Metal Rates Sheet “DBRates.xls”; and 

the “Margin” for each of Platinum and Rhodium shall be [***] basis points from the Restatement Date through and including
the Existing Termination Date and thereafter, [***] basis points. 
  

	4.2	The Lease Rent for the Metal will be payable in immediately available funds on each Payment Date. Lessee agrees that time is of the essence to Lessor in Lessee’s
making payments of the Lease Rent when such payment is due.

Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

 CONFIDENTIAL TREATMENT REQUESTED 

 

	4.3	With respect to each Lease, in the event that the period between the Commencement Date and the first Payment Date for such Lease and/or the period between the
penultimate Payment Date and the Termination Date for such Lease is not a full calendar month, the Lease Rent for such Lease shall be apportioned based on the number of days in such period. 

 

	4.4	Lessee’s and each Guarantor’s obligation to pay any amount payable hereunder or under any Lease (including, without limitation, Lease Rent, Consideration or
any indemnification obligation) shall be absolute and unconditional and shall not be affected by any circumstance, including any setoff, counterclaim, recoupment, defense or other right that Lessee or any Guarantor may have against the Lessor, its
Affiliates or any other person for any reason whatsoever. 

  

	5.	Delivery 

 The Metal
Amount set out in each Lease shall be deemed to have been delivered by Lessor to Lessee on the Commencement Date for such Lease at the Location specified in such Lease. 

 

	6.	Change Outs and Refabrication and Fabrication of Metal 

  

	6.1	Change Out for any Yarns Lease: 

  

	 	(a)	Where acting as a reasonable and prudent operator Lessee determines that a Unit under a Yarns Lease needs to be refurbished, and so long as no Default exists and is
then continuing, Lessee may on any date (the “Change Out Date”) replace such Unit (an “Old Unit”) with a replacement Unit (a “New Unit”) (such transaction, a “Change Out”). Lessee
shall notify Lessor in writing as soon as practicable of the intended Change Out Date, which notice shall specify the serial number of the Unit to be Changed Out. Lessee may then, in lieu of terminating the relevant Lease, amend the relevant Lease
so the Unit identification/serial number of the Old Unit (as contained in the terms of the Lease which relates to the Old Unit) is deleted and replaced with the Unit Identification/serial number of the New Unit, and in such event, effective
immediately on the Change Out Date the New Unit shall be deemed to be delivered by Lessee, and full and unencumbered title in the New Unit shall be automatically transferred from Lessee to Lessor in consideration of full and unencumbered title to
the Old Unit passing from Lessor to Lessee and such new Unit shall be subject to the terms and conditions hereof and the applicable Lease. 

  

	 	(b)	Lessee hereby acknowledges and agrees that if Change Outs for any trailing thirty (30) day period exceed 15% of aggregate Metal Amount, Lessee will immediately
provide Lessor an updated Inventory listing. 

  

	6.2	Refabrication and Fabrication for any CFM Lease: 

  

	 	(a)	For any CFM Lease, and so long as no Default exists and is then continuing, Lessee shall be allowed on any date to refabricate or fabricate the Metal in a Unit into one
or more new Units (“Refabrication” or “Fabrication”).

 22 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	
may acquire) any right, title or interests of Lessee in and to (i) the Units listed in the Inventory, as updated from time to time, including all Non-Leased Lessor Rhodium contained therein
and all Metal contained therein, but excluding, for the avoidance of doubt, any Non-Lessor Metal; (ii) the Unallocated Rhodium Account; (iii) all Rhodium therein or represented thereby; (iv) Lessee’s books and records, but solely
as they relate to the Specified Assets (as defined below); and (v) all products and proceeds of the foregoing (the “Specified Assets”), as security for the payment and performance in full of all of Lessee’s obligations
under the Operative Documents (including, without limitation, any Consideration, Lease Rent, fees, late charges and interest payable hereunder or under the Leases after the filing of a petition under the Bankruptcy Code, whether or not such
Consideration, Lease Rent, fees, late charges and interest are allowed in the bankruptcy proceeding (collectively, “Post-Petition Amounts”)); provided, that, with respect to the Unallocated Rhodium Account, the Rhodium therein or
represented thereby, the books and records relating thereto and the products and proceeds of the foregoing, Lessor hereby acknowledges and agrees that the aggregate dollar value (such value to be calculated based on the Benchmark Value) of such
security interest shall in no event exceed the dollar value of the lesser of (a) thirty-five percent (35%) of the aggregate dollar value of the Platinum subject to one or more Yarns Leases in accordance with the terms hereof, and
(b) $24,400,000. Such Lien shall remain in full force and effect until, and shall terminate upon, indefeasible payment and performance in full of all of such obligations (including, without limitation, any Post-Petition Amounts). Lessee agrees
to promptly execute and deliver, and hereby authorizes Lessor to file without Lessee’s signature (to the extent permitted by applicable law), all further instruments and documents as Lessor may reasonably request, in order to perfect, preserve
and protect the Lien granted hereby or to enable Lessor to exercise and enforce its rights and remedies hereunder with respect to such Lien, including financing or continuation statements, clarifications or amendments thereto. If any Default by
Lessee of its obligations under this Agreement or the Leases shall have occurred and be continuing, Lessor may exercise in respect of such Lien, in addition to other rights and remedies provided for herein or otherwise available to it, all the
rights and remedies of a secured party under the Bankruptcy Code or under the Uniform Commercial Code, as enacted in the State of New York (the “UCC”), including, without limitation, exercising its control over any
“account” (as such term is defined in the UCC), and without notice except as specified below or, if notice cannot be waived under the UCC, as required to be provided by the UCC, sell the collateral that is the subject of the Lien or any
part thereof in one or more parcels at public or private sale, at any of Lessor’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as Lessor may deem commercially reasonable. 

 

	12.2	Lessor and Lessee agree that for the duration of this Agreement and any Lease, if after the date hereof a change in tax law occurs adversely affecting the tax treatment
of the lease transactions contained herein and therein, Lessor and Lessee agree that they shall cooperate in optimizing the structure of this Agreement and the Leases to minimize taxes payable by Lessor and Lessee as permissible by applicable law to
the mutual benefit of Lessor and Lessee, including such changes or permissible restructurings as may be beneficial to Lessor and Lessee in execution of their Tax Obligations hereunder and excluding changes that would be prejudicial to either Lessor
or Lessee. 

  
 23 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	13.	Force Majeure 

 If the
performance of any obligation under this Agreement is prevented by an event beyond the control and without the fault or negligence of the Party affected thereby including acts of God or the public enemy; acts, laws, orders or regulations or any
government or department or agency thereof; wars or other civil or military disturbances, such Party will be excused from such performance to the extent of the duration of such interference or the direct effects thereof; provided,
however, that the duration of any such period in which such Party will be excused from performance will not exceed one (1) month and provided further that Lessee shall continue to pay the Lease Rent provided that Metal had been
previously delivered by Lessor to Lessee. If this period of one month is exceeded, then Lessor and Lessee will meet in order to decide whether and under what condition this Agreement can be performed. 

 

	14.	Indemnities 

 Lessee shall
within five (5) Business Days of notice by Lessor indemnify in full and hold harmless, Lessor, its officers, employees, agents, advisors, consultants and legal counsel and Lessor’s successors and assigns, (each an “Indemnified
Person”) from and against any and all claims (whether or not successful, compromised or settled), actions, liabilities, demands, proceedings or judgments which may be instituted, made, threatened, alleged, asserted or established (each a
“Claim”) in any jurisdiction against or otherwise involving an Indemnified Person and from all losses, costs, damages, charges or out-of-pocket expenses (including reasonable and documented fees and expenses of outside counsel;
provided that all documentation shall be subject to redaction for privilege, confidentiality and similar purposes) (each an “Expense”) which an Indemnified Person suffers or incurs from time to time (including all Expenses
reasonably incurred in disputing any Claim and/or in establishing a right to be indemnified pursuant to this clause 14 and/or in seeking advice regarding any Claim or in any way related to or in connection with this indemnity), in any such case
arising out of any Lessee’s or any Guarantor’s performance under any Operative Document, including, without limitation, the purchase, ownership, delivery, lease, possession, maintenance, condition, use or return of the Metals or the Units,
the operation of Lessee’s business, any Change Out, Fabrication or Refabrication or any Tax Obligations; provided that Lessee shall not be required to indemnify any Indemnified Person pursuant to this clause 14 if, but only to the extent
that, it is determined by final order of a court of competent jurisdiction or a Tribunal that such Claims and Expenses were the result of such Indemnified Peron’s gross negligence or willful misconduct. For the sake of clarity, it is the
intention of Lessee under this clause 14 to indemnify the Indemnified Persons from all Claims brought by Lessee, any successor in interest of Lessee or any person, whether acting on its own behalf or acting on behalf of Lessee, or asserting a Claim
through Lessee against an Indemnified Party and all Expenses related thereto. 

  
 24 

 CONFIDENTIAL TREATMENT REQUESTED 

 

 Unless otherwise agreed, Lessee will be the party directly responsible for calculating,
filing and/or otherwise reporting, and paying any and all Tax Obligations indemnified under this clause 14 (but only to the extent such indemnified Tax Obligations are or should with reasonable care be known to Lessee or with respect to which Lessor
has notified Lessee in writing) in a timely manner that is compliant with all applicable tax laws and rules including but not limited to any and all tax or tax related returns, reports, self assessments, renditions or other documents required or
associated with any taxes that may be due pursuant to this Agreement and any Lease, any transactions and/or any payments associated with or contemplated hereby. For the avoidance of doubt, nothing in this paragraph shall affect Lessee’s
obligation to indemnify Lessor pursuant to the first paragraph of this clause 14. 
 Lessee shall provide any exemption
certificate or other documentation necessary to demonstrate that no tax is due or that said tax has been paid to the tax notice address set forth in clause 19 within fifteen (15) days of receiving a request from Lessor for same. 

If Lessor is a “United States person” (as defined in Section 7701(2)(30) of the Internal Revenue Code), it shall deliver to
Lessee two original copies of Internal Revenue Service Form W-9 properly completed and duly executed by such Lessor, certifying that such Lessor is not subject to U.S. back-up withholding pursuant to Section 3406 of the Internal Revenue Code
and providing such other information as is required by such Form W-9. If Lessor is not a “United States person” (as defined in Section 7701(2)(30) of the Internal Revenue Code) and Lessor is entitled to an exemption from or reduction
of withholding taxes with respect to payments under this Agreement, Lessor shall deliver to Lessee such properly completed and executed documentation prescribed by applicable law or reasonably requested by Lessee as will permit such payments to be
made without withholding or at a reduced rate. 
  

	15.	Limitation of Liability 

In no event shall Lessor be responsible or liable to Lessee for any damages of any nature whatsoever (including, without limitation, any
special, indirect, incidental, punitive, exemplary or consequential damages or any damages incurred as a result of loss of use, loss of profits or revenue, interest charges or cost of capital), whether such claim is based in contract, warranty,
negligence or strict liability, arising out of, based upon or in connection with, whether directly or indirectly (a) the operation of Lessee’s business including the use of any Units or (b) any Change Out, Fabrication or
Refabrication; provided that the limitation of liability in this clause 15 shall not apply if it is determined by final order of a court of competent jurisdiction or a Tribunal that Lessee’s damages were the result of Lessor’s gross
negligence or willful misconduct. 
  

	16.	Further Assurances 

Lessee shall promptly and duly execute and deliver to Lessor such further documents and assurances and take such further action as may
from time to time be reasonably requested in order to more effectively carry out the intent and purposes of this Agreement.

	18.	Amendments 

 Neither this
Agreement nor any of the Leases may be amended except in writing signed by each Party. Notwithstanding the previous sentence, upon delivery of an Inventory by Lessee to Lessor in accordance with the terms hereof and without any additional action by
either Lessor or Lessee, (a) Schedule 3 hereto shall be deemed to have been updated and (b) this Agreement shall be automatically amended to incorporate such update.

	21.1	Dispute Resolution. If there shall be any dispute, controversy or claim (“Dispute”) between the Parties arising out of, relating to, or
connected with the Operative Documents, the breach, termination or invalidity hereof, or the provisions contained herein or omitted herefrom, the Parties shall use their best efforts to resolve the matter on an amicable basis and in a manner fair
and equitable to the Parties. If one Party notifies the other Party that a Dispute has arisen and the Parties are unable to resolve such Dispute within ten (10) days from such notice, then the matter shall be referred to the Chief Operating

 CONFIDENTIAL TREATMENT REQUESTED 

 

	21.2	Arbitration. The Parties irrevocably agree that any Disputes that are not resolved in accordance with clause 21.1 hereof shall be finally settled by arbitration
in New York City, New York, by three arbitrators (a “Tribunal”) appointed and proceeding in accordance with the Rules of Arbitration (the “ICC Rules”) of the International Chamber of Commerce (the
“ICC”) as the exclusive means of resolving such disputes. For purposes of appointing such arbitrators, each Party shall appoint one arbitrator. The third arbitrator shall be selected by the two Party-appointed arbitrators or,
failing agreement within five (5) days after the Party-appointed arbitrators have been confirmed, by the ICC in accordance with the ICC Rules. In addition: 

 

	 	(a)	All submissions and awards in relation to arbitration tinder this Agreement shall be made in English and all arbitration proceedings and all pleadings shall be in
English. 

  

	 	(b)	Any monetary award shall be made in U.S. Dollars. 

  

	 	(c)	Any award shall be final and not subject to appeal and the Parties hereby waive all challenge to any award by the arbitrators under this clause 21.2. The decision of
the arbitrators shall be final and binding on the Parties and may be presented by any Party for enforcement in any court of competent jurisdiction. In any such enforcement action, irrespective of where it is brought, no Party will (and the Parties
hereby waive any right to) seek to invalidate or modify the decision of the arbitrators or otherwise to invalidate or circumvent the procedures set forth in this clause 21.2. Further, the Parties understand and agree that the provisions of this
clause 21.2 may be specifically enforced by injunction or otherwise in any court of competent jurisdiction. 

  

	 	(d)	The fees and expenses, if any, of the arbitrators shall be shared by the Parties in inverse proportion to their respective success on the merits and such allocation of
fees and expenses shall be calculated by the arbitrators and shall be conclusive and binding on the Parties. 

  

	 	(e)	Except as may be required by applicable law, stock exchange rules, governmental authorities, or in connection with the ordinary course operation of their respective
businesses, the Parties agree to maintain confidentiality as to all aspects of the arbitration, including its existence and results, except that nothing herein shall prevent any Party from disclosing information regarding the arbitration for
purposes of enforcing the judgment of the arbitral tribunal or in any court proceedings involving the Parties. The Parties further agree to obtain the arbitral tribunal’s agreement to preserve the confidentiality of the arbitration.

  

	 	(f)	 Notwithstanding the foregoing Dispute Resolution and Arbitration provisions, the Parties acknowledge that remedies contained in the foregoing Dispute
Resolution and Arbitration provisions and at law may be inadequate to protect a Party (the “Affected Party”) against any breach of this Agreement by the other Party or by the other Party’s professional advisers, directors,
officers, servants

or employees and without prejudice to any other rights and remedies otherwise available to the Affected Party, the non-Affected Party agrees to the granting of injunctive relief in the Affected
Party’s favor without proof of actual damages provided, however, that the Affected Party shall not be relieved from proving any breach hereunder. In such circumstances, the Parties submit to the non-exclusive jurisdiction of the federal and
state courts of New York located in New York County.

	27.	Guarantee. 

  

	 	(a)	Guarantee of Guaranteed Obligations. 

  

	 	(i)	 Each Guarantor, jointly and severally, hereby unconditionally and irrevocably guarantees (this “Guarantee”) to and for the benefit of
Lessor, as primary obligor and not merely as surety, the due and punctual payment in full by Lessee of all amounts, including reimbursement obligations, fees, indemnities, costs, expenses, Post-Petition Amounts or otherwise, which are or may become
due and payable by, and the due and punctual performance and discharge by Lessee of all covenants, representations, warranties, undertakings and other obligations and liabilities of, Lessee to or in favor of Lessor under any of the Operative
Documents (the “Guaranteed Obligations”) or with respect to the 

  
 30 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	
Guaranteed Obligations that have not been fully paid or performed, as the case may be, on the due date thereof. Each Guarantor further agrees, jointly and severally, that the date on which any
Guaranteed Obligation is due may be extended without notice to or further assent from it and that it will remain bound upon this Guarantee notwithstanding any extension of any Guaranteed Obligation. Subject to clause 27(k), this Guarantee shall
survive the termination, rejection or expiration of this Agreement or any Lease. 

 Each Guarantor,
and by its acceptance of this Guarantee, Lessor, hereby confirms that it is the intention of all such persons that this Guarantee and the Guaranteed Obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for
purposes of Bankruptcy Law (as hereinafter defined), the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guarantee and the Guaranteed Obligations of
each Guarantor hereunder. To effectuate the foregoing intention, Lessor and the Guarantors hereby irrevocably agree that the Guaranteed Obligations of each Guarantor under this Guarantee at any time shall be limited to the maximum amount as will
result in the Guaranteed Obligations of such Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance. For purposes hereof, “Bankruptcy Law” means the Bankruptcy Code, as now or hereafter amended, the law, rules
or regulations applicable to any proceeding of the type referred to in clause 8.1(f), or any similar foreign, federal or state law for the relief of debtors or insolvent entities, insolvency or receivership. 

In furtherance of the foregoing and not in limitation of any other right which Lessor may have at law or in equity against
Lessee or any other person by virtue of this Agreement or against any Guarantor by virtue hereof, upon the failure of Lessee to pay or perform any Guaranteed Obligation for any reason when and as the same shall become due, Guarantor hereby promises
to and will immediately pay, or cause to be paid, in cash, to Lessor an amount equal to the sum of the unpaid amount of such Guaranteed Obligation and accrued and unpaid interest (if any), at the Late Charge Rate, on such unpaid Guaranteed
Obligation, and perform, or cause to be performed, each such Guaranteed Obligation. 
 This Guarantee is a
guarantee of payment and performance and not of collection and each Guarantor waives any right to require that any action against Lessee or any other person be taken or exhausted prior to action being taken against such Guarantor. Each Guarantor
specifically agrees, jointly and severally, that it shall not be necessary or required, and that each Guarantor shall not be entitled to require, that Lessor: (A) file suit or proceed to obtain or assert a claim against Lessee or any other
person for the Guaranteed Obligations; (B) make any effort at collection of the Guaranteed Obligations from Lessee or any other person; (C) foreclose against or seek to realize upon any security now or hereafter existing for the Guaranteed
Obligations; or (D) file suit or proceed to obtain or assert a claim for personal judgment against any other person liable for the Guaranteed Obligations, or make any effort at collection of the Guaranteed Obligations from any such other
person, or exercise or assert any other right or remedy to 

  
 31 

 CONFIDENTIAL TREATMENT REQUESTED 

 

 
which Lessor is or may be entitled in connection with the Guaranteed Obligations or any security or other guarantee therefor; or (E) assert or file any claim against the assets of Lessee or
any other guarantor or any other person liable for the Guaranteed Obligations, or any part thereof, either before or as a condition to enforcing the liability of each Guarantor under this Guarantee or requiring payment of the Guaranteed Obligations
by each Guarantor hereunder. 
  

	 	(ii)	Each Guarantor hereby specifically agrees, jointly and severally, that it shall not be necessary or required in order to enforce its obligations hereunder that there
be, and specifically waives, diligence, presentment, demand, protest or notice of any kind whatsoever with respect to this Guarantee or the Guaranteed Obligations, including without limitation: (A) notice of acceptance of this Guarantee or
notice of nonpayment or nonperformance of any of the Guaranteed Obligations; (B) demand for payment or performance from Lessee; (C) presentment for payment upon Lessee or the making of any protest; (D) notice of the amount of the
Guaranteed Obligations outstanding at any time; (E) notice of failure to perform on the part of Lessee or notice of dishonor or acceleration; (F) any requirement to exhaust any remedies exercisable upon a Default under any of the Operative
Documents; (G) any notice of any sale, transfer or other disposition of any right, title to or interest in the Metals, or any part thereof; or (H) any other circumstance whatsoever which might otherwise constitute a legal or equitable
discharge, release or defense of a guarantor or surety or which might otherwise limit recourse against each Guarantor. Each Guarantor agrees, jointly and severally, that any repayment of the Guaranteed Obligations guaranteed hereunder or other act
which tolls any statute of limitations applicable thereto shall similarly operate to toll such statute of limitations applicable to any liability of each Guarantor hereunder. Each Guarantor waives all rights and benefits under any statute or rule of
law requiring the holder or holders of any promissory note to pursue the maker thereof, any security which said holder or holders may hold, or any other remedy before proceeding against each Guarantor. Each Guarantor waives all rights and benefits
under any applicable law (to the extent applicable to each Guarantor hereunder) purporting to reduce a guarantor’s obligation in proportion to the principal obligation guaranteed. Each Guarantor does hereby waive and relinquish, so far as it
may lawfully and effectively do so, the benefit and advantage of any and all valuation, stay, appraisement, extension or redemption laws which, but for this provision, agreement and waiver, might be applicable to any sale made under any judgment,
order or decree of any court or otherwise based on this Guarantee, any of the Operative Documents or on the Lien of Lessor under this Agreement. 

  

	 	(iii)	 The obligations of each Guarantor hereunder shall be absolute and unconditional, shall remain in full force and effect until irrevocable payment,
performance or observance in full of all of the Guaranteed 

  
 32 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	
Obligations and shall not in any manner be affected by reason of any action taken or not taken by Lessor or any other person or of any lack of prior enforcement or retention of any rights against
Lessee or each Guarantor or any illegality, unenforceability or invalidity of the Guaranteed Obligations, any of the Operative Documents, any other guarantee or other obligations, or any other agreement or instrument referred to herein or therein,
or any substitution, release or exchange of any other guarantee of or security for any of the Guaranteed Obligations, or any other circumstance or condition (whether or not any Guarantor or Lessee shall have any knowledge or notice thereof),
including without limitation: 

  

	 	(A)	any termination, amendment or modification of, or deletion from, or addition or supplement to, or other change in any of the Operative Documents, or any other
instrument or agreement applicable to any of the Parties to such agreements, or to the Metals, or any furnishing or acceptance of additional security, or any release of any security, for the obligations of Lessee under any of the Operative Documents
or the failure of any security or the failure of any person to perfect any interest in any collateral security; 

  

	 	(B)	any failure, omission or delay on the part of Lessee or any other person to conform or comply with any term of any of the Operative Documents; 

 

	 	(C)	any exercise or nonexercise of any right, remedy, power or privilege under or in respect of any of the Operative Documents or any obligation or liability contained
therein; 

  

	 	(D)	except to the extent thereof, any waiver by Lessor, or their successors or assigns, of the performance or observance by Lessee of any Guaranteed Obligation, or any
default under any Agreement or the Leases, or the extension or renewal of any of the Operative Documents or any change in the provisions of any of the Operative Documents, or any extension of time for payment of any Guaranteed Obligation, or of the
time for performance of any other obligations, covenants or agreements under or arising out of any of the Operative Documents, or the extension or the renewal of any thereof; 

 

	 	(E)	any failure, omission or delay on the part of Lessor, or its successors or assigns, to notify any Guarantor of any default under any of the Operative Documents or to
enforce, assert or exercise any right, power or remedy conferred on it in this Guarantee, or any such failure, omission or delay on the part of Lessor in connection with any of the Operative Documents or any other action on the part of Lessor;

  
 33 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	(F)	any voluntary or involuntary bankruptcy, insolvency, reorganization, arrangement, readjustment, assignment for the benefit of creditors, composition, receivership,
conservatorship, custodianship, liquidation, marshalling of assets and liabilities, liquidation, or similar proceedings with respect to Lessee, each Guarantor, any other person or any of their respective properties or creditors, or the disaffirmance
with respect to Lessee of any of the Operative Documents in any such proceeding or any action taken by any trustee or receiver or by any court in any such proceeding; 

 

	 	(G)	any limitation on the liability or obligations of Lessee or any Guarantor or any discharge, termination, cancellation, frustration, irregularity, invalidity or
unenforceability, in whole or in part, of any of the Operative Documents; 

  

	 	(H)	any defect in the title, compliance with specifications, condition, design, operation or fitness for use of, or any damage to or loss or destruction of, the Metals or
Units, or any interruption or cessation in the use of the Metals or Units by Lessee or any other person for any reason whatsoever (including without limitation any governmental or military authority, or any act of God or of the public enemy)
regardless of the duration thereof (even though such duration would otherwise constitute a frustration of the Leases), whether or not resulting from accident and whether or not without fault on the part of Lessee or any other person;

  

	 	(I)	any merger or consolidation of Lessee or any Guarantor into or with any other person, or any sale, lease or transfer of any of the assets of Lessee or any Guarantor to
any other person; 

  

	 	(J)	any compromise, settlement, release, renewal, extension, indulgence, change in or waiver or modification of any Guaranteed Obligation, or any failure to mitigate

which Lessee is a party; 

  

	 	(K)	any transfer or permitted assignment by Lessor, or its successors or assigns of its interest, or any part thereof, in and to any Operative Document or the assignment or
transfer of any rights relating to any Guaranteed Obligation contained in any Operative Document, including, without limitation, the full or partial assignment of any of the Operative Documents; 

  
 34 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	(L)	any defense, setoff, cross-claim or counterclaim which may at any time be available to or asserted by or against Lessee or any Guarantor; 

 

	 	(M)	any misrepresentation or breach of warranty made by Lessee in any Operative Document to which Lessee is a party or in any certificate or document delivered in
connection therewith; 

  

	 	(N)	the genuineness, legality, validity or enforceability of any Operative Document, or of any assignment or termination of any such Operative Document; and

  

	 	(O)	any other condition or circumstance which might otherwise constitute a legal or equitable discharge, release or defense of a surety or guarantor, or which might
otherwise limit recourse against any Guarantor, including, without limitation, any discharge, release, defense or limitation arising out of any laws of the United States of America or any state thereof which would either exempt, modify or delay the
due or punctual payment and performance of the obligations of any Guarantor hereunder, it being agreed that the obligations of each Guarantor hereunder shall not be discharged except by payment or performance as herein provided.

 Each Guarantor hereby waives and shall not assert any of the foregoing occurrences as a defense
to its obligations hereunder. Without limiting the foregoing, it is understood that repeated and successive demands may be made and recoveries may be made hereunder as and when, from time to time, Lessee shall default under the terms of any
Operative Document, and that this Guarantee shall remain in force and effect and shall apply to each and every subsequent default. No failure or delay in exercising any right under this Guarantee shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right of Lessor under this Guarantee or the Operative Documents. 

 

	 	(iv)	Each Guarantor assumes full responsibility, jointly and severally, for keeping fully informed of the financial condition of Lessee and all other circumstances
materially affecting Lessee’s ability to perform the Guaranteed Obligations, and agrees that Lessor shall not have any duty to report to any Guarantor any information which it receives about Lessee’s financial condition, business
operations or any circumstances bearing on its ability to perform its duties under the Operative Documents. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Guaranteed Obligations and notice of or
proof of reliance by Lessor upon this Guarantee or acceptance of this Guarantee. The Guaranteed Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Guarantee, and all dealings
between Lessee or any Guarantor and Lessor shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guarantee. 

  
 35 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	(v)	Each Guarantor agrees, jointly and severally, that if at any time all or any part of any payment or performance theretofore applied by Lessor to any of the Guaranteed
Obligations is or must be voided, rescinded or returned by Lessor for any reason whatsoever (including without limitation the insolvency, bankruptcy or reorganization of Lessee, any Guarantor or any other person), such Guaranteed Obligations shall,
for the purposes of this Guarantee, to the extent that such payment or performance is or must be voided, rescinded or returned, be deemed to have continued in existence, notwithstanding such application by Lessor, and this Guarantee shall continue
to be effective or reinstated as to such Guaranteed Obligations, all as though such application by Lessor had not been made. If an event permitting the declaration of default under an Operative Document shall at any time have occurred and be
continuing, and such declaration of default shall at such time be prevented by reason of the pendency against Lessee, each Guarantor or any other person of a case or proceeding under Bankruptcy Law, each Guarantor agrees that, for purposes of this
Guarantee and its obligations hereunder, such Operative Document shall be deemed to have been declared in default with the same effect as if such Operative Document had been enforceable in accordance with the terms thereof, and each Guarantor shall
forthwith pay the amounts specified by Lessor to be paid thereunder, any interest thereon and any other amounts guaranteed hereunder without notice or demand. Each Guarantor hereby agrees, jointly and severally, that it will pay to Lessor on demand
for all reasonable and documented costs and expenses (including without limitation reasonable and documented fees and expenses of outside counsel; provided that all documentation shall be subject to redaction for privilege, confidentiality and
similar purposes) incurred by Lessor in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar
payment under Bankruptcy Law. In case any Operative Document shall be terminated as a result of the rejection or disaffirmance thereof by any trustee, receiver, liquidator, agent or other representative of Lessee or any of its property in any
assignment for the benefit of creditors or in any bankruptcy, insolvency, reorganization, arrangement, readjustment, liquidation, dissolution of Lessee, or similar proceeding, each Guarantor’s obligations hereunder shall continue to the same
extent as if such Operative Document had not been so rejected or disaffirmed. Guarantor shall and does hereby waive all rights and benefits that might accrue to it by reason of any such assignment or proceeding and each Guarantor agrees that it
shall be jointly and severally liable for the full amount of the Guaranteed Obligations irrespective of and without regard to any modification, limitation or discharge of liability of Lessee that may result from or in connection with any such
assignment or proceeding. 

  
 36 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	(vi)	Lessor may, in its discretion, at any time and from time to time, without any Guarantor’s consent and without affecting the liability of each Guarantor under this
Guarantee, agree to amendments, modifications or supplements to the Operative Documents, give or withhold consents, waivers or approvals, and exercise, or refrain from exercising, rights under the Operative Documents, or: (a) renew, extend
(including extensions beyond the original term), modify, release or discharge any Guaranteed Obligation of Lessee, of co-guarantors (whether hereunder or under a separate instrument) or of any other party at any time directly or contingently liable
for the payment of any of said Guaranteed Obligations; (b) accept partial payments of said Guaranteed Obligations; (c) settle, release (by operation of law or otherwise), compound, compromise, collect or liquidate any of said obligations
and the security thereof in any manner; (d) consent to the transfer of security; or (e) bid and purchase at any sale of Metal or Units. 

  

	 	(vii)	Each Guarantor agrees, jointly and severally, that, as between each Guarantor and Lessor, the Guaranteed Obligations of Lessee may be declared to be forthwith due and
payable or, to be performed, as the case may be, as provided in the Operative Documents (and shall be deemed to have become automatically due and payable or, to be performed, as the case may be, in the circumstances provided for in the Operative
Documents) for purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such declaration (or such Guaranteed Obligations from becoming automatically due and payable or, to be performed, as the case may be)
and, in such event, such Guaranteed Obligations (whether or not due and payable or, to be performed, as the case may be, by Lessee) shall forthwith become due and payable by each Guarantor for purposes of this Guarantee. 

 

	 	(b)	Subrogation. 

  

	 	(i)	 Any claims of a Guarantor against Lessee or any other Guarantor to which a Guarantor may be or become entitled (including, without limitation, claims
by subrogation or otherwise by reason of any payment or performance by the Guarantor in satisfaction and discharge, in whole or in part, of its obligations under this Guarantee) shall be and hereby are made subject and subordinate to the prior
payment or performance in full of the Guaranteed Obligations. In furtherance of the foregoing, each Guarantor hereby agrees that until the payment and performance in full in cash of all Guaranteed Obligations and the expiration and termination of
this Agreement, it shall not assert or bring any claim and shall not exercise any right or remedy arising by reason of any performance by it of its Guarantee in clause 27(a) hereof, whether by subrogation or otherwise,

  
 37 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	
against Lessee or any other Guarantor of any of the Guaranteed Obligations. Any amount paid to a Guarantor on account of any such subrogation or other rights prior to such payment, satisfaction,
expiration and termination shall be held in trust for the benefit of Lessor and shall immediately be paid and turned over to Lessor in the exact form received by the Guarantor (duly endorsed in favor of Lessor, if required), to be credited and
applied against the Guaranteed Obligations, whether matured or unmatured. In furtherance of the foregoing, at all times prior to such payment, satisfaction, expiration and termination, each Guarantor shall refrain from taking any action or
commencing any proceeding against Lessee or any other Guarantor (or its successors or assigns, whether in connection with a bankruptcy proceeding or otherwise) to recover any amounts in respect of payments made under this Guarantee to Lessor.

  

	 	(ii)	Notwithstanding the immediately preceding paragraph, each Guarantor agrees, jointly and severally, that it will never have, and hereby waives and disclaims, any claim
or right by way of subrogation or otherwise in respect of any payment that it may be required to make hereunder, to the extent that such claim or right would cause it to be a “creditor” for purposes of the Bankruptcy Code, as now or
hereafter amended, or any Bankruptcy Law. 

  

	 	(c)	Rights and Powers. Guarantor hereby irrevocably authorizes and empowers Lessor in its discretion to take such proceedings, in its own name or otherwise, for the
enforcement of or collection of any amounts due under this Guarantee, as Lessor may deem necessary or desirable. Lessor may proceed, either in its own name, or otherwise, to protect and enforce any or all of its rights under this Guarantee in
equity, at law or by other appropriate proceedings, whether for the specific performance of any covenants or agreements contained in this Guarantee or otherwise, under applicable law, and shall be entitled to require and enforce the performance of
all acts and things required to be performed hereunder by any Guarantor. 

  

	 	(d)	Remedies Cumulative, etc. No right, power or remedy conferred upon or reserved to Lessor this Guarantee is intended to be exclusive of any other right, power or
remedy and, to the extent permitted by law, each and every right, power and remedy of Lessor pursuant to this Guarantee or the Operative Documents or now or hereafter existing at law or in equity or by statute or otherwise shall be cumulative and
concurrent and shall be in addition to every other right, power or remedy pursuant to this Guarantee or the Operative Documents or now or hereafter existing at law or in equity or by statute or otherwise, and the exercise or beginning of the
exercise by Lessor of any one or more of such rights, powers or remedies shall not preclude the simultaneous or later exercise by Lessor of any or all such rights, powers or remedies. 

 

	 	(e)	Assignment. No Guarantor may assign its obligations under this Guarantee without the prior written consent Lessor, and no assignment by any Guarantor shall
release such Guarantor from its obligations under this Guarantee without the written consent of Lessor. 

  
 38 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	(f)	Attorneys’ Fees. Each Guarantor agrees, jointly and severally, to pay to Lessor any and all reasonable and documented costs and expenses (including
reasonable and documented fees and expenses of outside counsel; provided that all documentation shall be subject to redaction for privilege, confidentiality and similar purposes) incurred by Lessor in successfully enforcing this Guarantee and in
connection with the execution of any Guarantor Joinder, together with any reasonable and documented costs and expenses, including reasonable fees of outside counsel, incurred on account of the bankruptcy or insolvency of any Guarantor.

  

	 	(g)	Payments. All payments by each Guarantor under this Guarantee in respect of any Guaranteed Obligation shall be made in immediately available funds. Except as
otherwise provided below, all payments by any Guarantor as required under this Agreement shall be made without deduction of or withholding for or on account of or liability for any present or future taxes collected by way of withholding or
deduction. Except as otherwise provided below, if any such taxes are so levied or imposed, each Guarantor agrees to pay such taxes and an additional amount such that the net amount actually received by Lessor, after such withholding, shall equal the
full amount of the payment then due and shall be free of expense to Lessor for collection or other charges. 

  

	 	(h)	Further Assurances. Each Guarantor shall promptly and duly execute and deliver to Lessor such further documents and assurances and take such further action as
may from time to time be reasonably requested in order to more effectively carry out the intent and purposes of this Guarantee. 

  

	 	(i)	Performance. Performance by any Guarantor of any or all of the obligations of Lessee under and pursuant to the Operative Documents shall, for all purposes
thereof, constitute performance by Lessee of such obligations to the extent so performed by such Guarantor under this Guarantee. 

  

	 	(j)	 Domestic Subsidiaries. Within five (5) days following the formation of a Domestic Subsidiary by Lessee or any Subsidiary of Lessee (and, in
any event, no later than the date such Domestic Subsidiary becomes a guarantor or obligor under either of the Financing Agreements), Lessee shall cause such newly formed Domestic Subsidiary to guarantee payment of the Guaranteed Obligations by
(1) executing and delivering to Lessor a joinder in the form annexed hereto as Schedule 7 pursuant to which such Domestic Subsidiary shall guarantee all of the Guaranteed Obligations on the same terms of this Guarantee (a “Guarantor
Joinder”) and (2) delivering to Lessor an opinion of counsel reasonably satisfactory to Lessor to the effect that joinder has been duly executed and delivered by such Domestic Subsidiary and is in compliance with the terms of this
Agreement (collectively, “Guarantee Documents”). Upon the execution of any such joinder, the obligations of the Guarantors and any 

  
 39 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	 	
Domestic Subsidiary which becomes a Guarantor shall become joint and several and each reference to the “Guarantor” in this Agreement shall be deemed to refer to all Guarantors,
including such Domestic Subsidiary. 

  

	 	(k)	Automatic Release. So long as no Default has occurred and is continuing; 

 

	 	(i)	If (a) all Leases of Metals used by any Guarantor in the conduct of its Business are terminated in accordance with clause 7.6 and such Leases are settled in
accordance with clause 7.2 and (b) such Guarantor is irrevocably released from its obligations under the Credit Agreement in connection with a sale or other disposition permitted thereunder, such Guarantor shall be automatically released from
its Guarantee and other obligations hereunder. 

  

	 	(ii)	If this Agreement and all Leases of Metals and Units are terminated in accordance with clause 7.1 or 7.6 and all such Leases are settled in accordance with clause 7.2
and all obligations hereunder shall have been paid in full and terminated irrevocably, the Lessor shall (x) release its Lien on the Specified Assets and (y) at Lessee’s expense, execute and deliver such documents as Lessee shall
reasonably request to evidence the release of any Guarantee or Lien pursuant to this clause 27(k).
