This Amended and Restated Facility Lease Agreement (this “Lease”) is entered into by Platypus Development LLC, a Delaware limited liability company (“Landlord”) and GTAT Corporation, a Delaware corporation (“Tenant”), effective as of December 15, 2014 (the “Effective Date”). Any capitalized terms used in this Lease shall have the meanings assigned to them in the Glossary attached as Exhibit A, or if not defined in Exhibit A, those assigned to them in the Amended Settlement Agreement (as hereinafter defined).

A.    Landlord and Tenant entered into the Facility Lease Agreement dated as of October 31, 2013 (the “Original Lease”) with respect to the Premises (as hereinafter defined).

B.    Landlord and Tenant are entering into this Amended and Restated Facility Lease Agreement pursuant to the terms of the Amended and Restated Adequate Protection and Settlement Agreement made and entered as of December 15, 2014, by and among (i) Apple Inc., a California corporation, (ii) Landlord, (iii) Tenant, and (iv) the affiliates of Tenant that are signatories thereto (as amended or restated from time to time, the “Amended Settlement Agreement”).

C.    In accordance with the Amended Settlement Agreement, Landlord and Tenant are concurrently entering into a lease (the “Warehouse Lease”) for a portion of the Premises (the “Storage Space”) that will commence upon the expiration of this Lease.

In consideration of the mutual covenants and agreements contained in this Lease, the receipt and sufficiency of which is acknowledged, Landlord and Tenant amend and restate the Original Lease in its entirety, and agree, as follows:

1.1    Premises. Landlord leases to Tenant and Tenant leases from Landlord, all of Landlord’s right, title and interest in and to: (a) the entire industrial building commonly known as 3740 South Signal Butte Road, Mesa, Arizona, containing approximately 1,328,075 rentable square feet, as such building has been improved by the Landlord Work (the “Building”), together with the land (the “Land”) on which the Building is located as more fully described in Exhibit B (collectively, the “Premises”); and (b) all fixtures, equipment and other improvements located at or within the Premises, including, without limitation, the fixtures and equipment to be installed by Landlord at its sole cost and expense as part of the Landlord Work. The Premises includes the exterior surfaces of the Building (including the structural walls, roof and roof membrane), as well as the interior and other portions and components of the Building, and related improvements (including any loading dock areas, equipment pads, cooling towers and other Exterior Areas) (collectively, the “Improvements”); provided that, the Premises shall in no event include, and Landlord reserves for its sole and exclusive use to provide electrical services to the Premises: (i) the Roof Solar Array; (ii) the Solar Basin; (iii) the Fuel Cell (if any); and (iv) the Electrical Substation (which shall be owned and operated by a utility provider) and the portion of the Land upon which any such Electrical Substation is located. Landlord further reserves a right of entry as reasonably necessary to maintain, repair, operate and monitor (or to cause the applicable utility provider to do the same) the Roof Solar Array, the Solar Basin, the Fuel Cell, and the Electrical Substation and portion of Land upon which the Electrical Substation is located,

which right of entry shall be subject to the terms of Section 9.1 and Section 9.6. The location and dimensions of the Building and the Land, as they exist as of the Effective Date, are depicted on the plan attached as Exhibit B-1 as “Phase 1”. The parties agree that the depiction of the Premises, the Building and the Land on Exhibit B-1, and any reference to square footage or dimensions do not constitute a representation, covenant or warranty of any kind by Landlord.

1.1.1    Landlord confirms to Tenant that it is the owner of the Premises and all of the fixtures, equipment and other improvements described in clause (b) of Section 1.1 existing at or within the Premises.

1.1.2    Prior to entering into the Original Lease, Tenant had the right, at Tenant’s sole cost and expense, to conduct or to cause to be conducted by reputable and qualified companies, at Tenant’s sole cost and expense, such audits, assessments, reviews, investigations, inspections, tests, and studies of the Premises, the environmental condition of the Premises, the condition of all buildings, structures and equipment on or within the Premises, the title to the Premises (including so-called survey matters), the compliance of the Premises with applicable Laws, such other engineering, legal and other matters relating to or affecting the Premises and any other investigation or study of the Premises not otherwise prohibited under the Original Lease as Tenant deemed necessary or desirable in connection with its lease of the Premises. Landlord made no representations or warranties as to the truth, accuracy or completeness of any of the Due Diligence Reports. It is the parties’ express understanding and agreement that all of the Due Diligence Reports and any other such materials were provided by Landlord solely for Tenant’s convenience in making its own examination of the Premises, and, in making such examination, Tenant relied exclusively on its own independent investigation and evaluation of the Premises and not on the Due Diligence Reports or any other materials supplied by Landlord or Landlord’s Agents. Any Studies undertaken by or on behalf of Tenant pursuant to this Section 1.1.2 shall be at Tenant’s sole risk and expense. All information regarding or relating to the Premises obtained by Tenant during any Study of the Premises shall be subject to Section 18.21 and held, maintained and treated by Tenant as private, confidential and privileged information. Tenant shall promptly deliver to Landlord, at no cost to Landlord, all third party reports, of the same type as the Due Diligence Reports, prepared for Tenant in connection with any Studies of the Premises. Tenant will indemnify Landlord, Buyer Agent and Seller (each, a “P&S Party”) against, and hold each P&S Party harmless from, any claims, loss, injury, liability, or damages (including reasonable attorneys' fees) incurred by such P&S Party as a result of persons or firms entering the Premises on Tenant’s behalf to complete any Study of the Premises as permitted under this Section 1.1.2.

1.1.3    Tenant hereby agrees that: (a) it has read, and (b) this Lease is subject to the following agreements: (i) Basin Array Access Agreement; (ii) Reliability Center Access Agreement; and (iii) the Access Agreement (collectively, the “Access Agreements”); provided that, Tenant’s obligations under this Lease shall not be materially increased, nor shall Tenant’s rights under this Lease be materially diminished, as a result of the Access Agreements.

1.2    Phased Delivery of Premises. The terms of Sections 1.2 through 1.6, inclusive, were included in the Original Lease. In connection with the amendment and restatement of this Lease, Landlord and Tenant have retained such terms for ease of reference, but neither Landlord nor Tenant shall have any further obligations under Sections 1.2 through 1.6, inclusive, from and after the Effective Date.

1.2.1    Phases. Landlord anticipates that it will deliver possession of the Premises to Tenant in multiple phases as each phase of the Premises (each, a “Phase”) becomes ready for delivery to Tenant. As used in this Lease, the term “Current Demised Premises” shall mean, at any given time, the Premises or the Phase(s), and the portion of the Premises corresponding to such Phase(s), of which Tenant has accepted delivery in accordance with Section 1.4. Exhibit C describes each of the nine (9) Phases of the Premises. The Phases are designated on Exhibit C as “Phase 1”, “Phase 2”, “Phase 3”, “Phase 4”, “Phase 5”,“Phase 6”, “Phase A”, “Phase B” and “Phase C”. Except as expressly set forth in Sections 1.2.2, 1.3 and 1.4, Landlord shall deliver each Phase of the Premises to Tenant in its then "as-is" condition without any representations or warranties regarding condition.

1.2.2    Landlord Work. For each Phase, Landlord, at its sole expense, shall: (a) deliver the portion of the Premises for such Phase as contemplated in the Phasing Plan (for each Phase, the “Applicable Phase Landlord Work”, and collectively for all Phases, the “Landlord Work”) in compliance with: (i) the Phasing Plan, (ii) the Approved Construction Documents, and (iii) all Laws; (b) satisfy the Acceptance Criteria (as described in the Phasing Plan) for such Phase; (c) deliver possession of the applicable Phase to Tenant free and clear of all tenants and other occupants and in good order, condition and repair, and with all Building Systems serving such Phase in the condition required of such Phase by the Phasing Plan; and (d) deliver to Tenant the Evidence of Completion with respect to such Phase (the requirements set forth in the foregoing clauses (a) through (d), inclusive, are referred to herein as the “Delivery Conditions”). Notwithstanding the foregoing, if a permanent certificate of occupancy is not available by the Applicable Delivery Date for a Phase due to Landlord Work remaining in subsequent Phases, then, in lieu of a permanent certificate of occupancy, Landlord may provide: (i) all required sign-offs and approvals from Governmental Authorities for: (A) Tenant to lawfully occupy and use the applicable Phase for the purpose contemplated by the Phasing Plan for such Phase (the “Applicable Phase Purpose”), and (B) issuance of a permanent certificate of occupancy in due course for such Phase, and (ii) a certificate from Landlord’s architect certifying to Tenant that all work for such Phase has been completed (other than Punch List items) in a manner that will allow for issuance of a permanent certificate of occupancy for such Phase for the Applicable Phase Purpose in due course. Landlord shall remain responsible for delivering a permanent certificate of occupancy for such Phase for the Applicable Phase Purpose once the required work in subsequent Phases is complete. Landlord shall undertake the Landlord Work in a good and workmanlike manner, employing materials of good quality, and in compliance with applicable Laws. Unless otherwise specified in the Phasing Plan or the Approved Construction Documents, Landlord shall undertake the Landlord Work in the manner and utilizing the practices and procedures, and using materials, finishes and construction techniques, that are selected by Landlord in its reasonable discretion, in consultation with Tenant, in furtherance of the preparation of the Premises for Tenant’s engagement in the manufacturing purposes contemplated under Section 4.1 of this Lease and the Collateral Agreements.

1.2.3    Preparation of Base Building Plans and Specifications.

1.2.3.1    Landlord’s architects and engineers shall prepare the Base Building Plans and Specifications consistent with all applicable Laws and the Phasing Plan. The parties acknowledge that Tenant shall have a significant role in the preparation of the Base Building Plans and Specifications and has special expertise with respect to the improvements required for Tenant’s Permitted Use. Landlord and Tenant shall work cooperatively and in good faith to develop and finalize the Base Building Plans and Specifications as expeditiously as reasonably practicable, in a manner designed to achieve simultaneous design review and input from both parties. To that end: (a) during preparation and review of the Base Building Plans and Specifications: (i) Tenant and its designated representatives and Landlord and Landlord’s architects and engineers shall meet or conference on a weekly basis to discuss the status of the Base Building Plans and Specifications; and (ii) Landlord will use good faith efforts to notify Tenant, and permit Tenant to join, any scheduled working meetings between Landlord and its architects and/or engineers, during which Landlord anticipates the parties, in discussing the Base Building Plans and Specs, will primarily focus on the operation of the Mesa Equipment and/or Tenant’s fabrication equipment; and (b) during construction of the Landlord Work: (i) Tenant and its designated representatives and Landlord and Landlord’s contractor shall meet or conference on a weekly basis to discuss the status of the construction of the Landlord Work; and (ii) Landlord will use good faith efforts to notify Tenant, and permit Tenant to join, any scheduled working meetings between Landlord and its general contractor, during which Landlord anticipates the parties, in discussing the construction of the Landlord Work, will primarily focus on the operation of the Mesa Equipment and/or Tenant’s fabrication equipment. During weekly meetings/conferences or any other meeting/conference attended by Tenant as permitted under this Section, Tenant agrees to: (A) provide Tenant’s operational perspective as to all issues discussed with respect to the Base Building Plans and Specifications; (B) pro-actively raise any concerns that the development of the Base Building Plans and Specifications may be inconsistent with the Phasing Plan, and propose reasonable resolutions to the same; and (C) otherwise participate in good faith in all such meetings/conferences in order to further the expeditious development of the Base Building Plans and Specifications and construction of the Landlord Work. Upon Tenant’s reasonable request, Landlord

shall provide (or shall cause its contractors to provide) to Tenant copies of current plans, drawings and specifications for the Landlord Work (collectively, the “Progress Plans”) for Tenant’s review; provided, however, Landlord shall not be held liable to any Tenant Party if Landlord, absent bad faith, inadvertently delivers to Tenant an incomplete or outdated version of any such Progress Plan, or fails to deliver any particular Progress Plan. Tenant agrees that Tenant shall provide any insight, concerns, issues, proposals and suggestions with respect to the Base Building Plans and Specifications and Progress Plans (“Tenant Feedback”) directly to Landlord, and shall only discuss Tenant Feedback with Landlord’s contractors if Landlord is present at such time and involved in such discussion.

1.2.3.2    Prior to submitting the Base Building Plans and Specifications to the applicable Government Authorities to obtain a building permit for the Landlord Work, Landlord shall furnish to Tenant a copy of the Base Building Plans and Specifications for Tenant’s review and approval; provided that, Tenant shall not withhold its approval of the Base Building Plans and Specifications so long as the Base Building Plans and Specifications comply with all Laws and are not materially inconsistent with the Phasing Plan. Tenant shall advise Landlord of Tenant’s approval or disapproval of the Base Building Plans and Specifications within three (3) Business Days after Landlord submits the Base Building Plans and Specifications to Tenant. If Tenant fails to respond within such three (3) Business Day period, Tenant will be deemed to have approved the Base Building Plans and Specifications submitted to Tenant for approval. If Tenant notifies Landlord of its reasonable objections, together with Tenant's recommendation of modifications reasonably required to make the Base Building Plans and Specifications acceptable to Tenant within such three (3) Business Day Period, Landlord will revise the Base Building Plans and Specifications to meet Tenant’s reasonable objections, and resubmit the Base Building Plans and Specifications to Tenant for its review and approval. Tenant shall advise Landlord of Tenant’s approval or disapproval of the revised Base Building Plans and Specifications within three (3) Business Days after Landlord submits the same, and such process shall continue until Tenant approves (or is deemed to have approved) the Base Building Plans and Specifications. If Tenant objects to the Base Building Plans and Specifications for the reason that the Base Building Plans and Specifications are materially inconsistent with the Phasing Plan, and Landlord disputes Tenant’s claim that such inconsistency between the Base Building Plans and Specifications and the Phasing Plan is material, then, either party may immediately submit the dispute to Expedited Arbitration.

1.2.3.3    Tenant’s authorized representative (who shall have an appropriate level of expertise with respect to the Landlord Work contemplated in the Phasing Plan) shall be available promptly upon Landlord’s request, and at Tenant’s cost, to consult and confer with Landlord about the Landlord Work, the Base Building Plans and Specifications and the Approved Construction Documents. Tenant acknowledges that this may require the authorized representative to be on-site during all or part of the construction period.

1.2.4    Change Orders.

1.2.4.1    Landlord may make changes to the Approved Construction Documents in accordance with the provisions of this Section 1.2.4.1. If Landlord desires to make a change to the Approved Construction Documents, Landlord shall deliver notice of the proposed change to Tenant, together with any material drawings, specifications and other documents necessary to show or describe the proposed change (“Change Order Documents”) (provided, however, Landlord shall not be held liable to any Tenant Party if Landlord, absent bad faith, inadvertently delivers to Tenant incomplete or Change Order Documents in connection with such change). If Landlord’s proposed change is a material change to the Approved Construction Documents, Landlord shall deliver a copy to Tenant of the Change Order Documents. As used herein, the term “material change” means a change to the Approved Construction Documents that: (a) directly and materially affects Tenant’s ability to grow and process sapphire boules in the Premises in accordance with the delivery schedule set forth in the MDSA SOW; or (b) requires the movement of manufacturing materials or Goods (as defined in the MDSA) in the Premises in an manner which would interrupt Tenant’s sapphire manufacturing process. If, within three (3) Business Days after the delivery of such Change Order Documents showing or describing the proposed material change to the Approved Construction Documents, Tenant gives notice to Landlord that Tenant objects to such change, which notice shall be accompanied by

Tenant's recommendation of any modifications reasonably required to make the change acceptable to Tenant, then Landlord shall either withdraw the proposed change or modify the same in accordance with Tenant's recommendation. If Tenant fails to respond to Landlord within three (3) Business Days after Landlord delivers the Change Order Documents, Tenant will be deemed to have approved such Change Order Documents.

1.2.4.2    Tenant may require Landlord to make changes to the Approved Construction Documents if: (a) absent such changes to the Approved Construction Documents: (i) Tenant’s ability to grow and process sapphire boules in the Premises in accordance with the delivery schedule set forth in the MDSA SOW would be directly and materially affected; or (ii) Tenant is required to move manufacturing materials or Goods in the Premises in a manner which would interrupt Tenant’s sapphire manufacturing process; (b) such changes comply with all Laws; (c) such changes are consistent with design review requirements of the Master Developer and Governmental Authorities pursuant to applicable Law; (d) such changes are not inconsistent with any express provision of the Phasing Plan; (e) such changes do not materially reduce the quality of the Landlord Work, as determined by Landlord in its reasonable discretion; and (f) Tenant is responsible for all costs and expenses and all delays resulting from such change, including without limitation costs or expenses relating to: (1) any additional architectural or engineering services and related design expenses, (2) any changes to materials in process of fabrication, (3) cancellation or modification of supply or fabricating contracts, (4) removal or alteration of work or plans completed or in process, and (5) delay claims made by any subcontractor (collectively, the “Cost and Delay Liability”). Tenant may not require Landlord to make any other change to the Approved Construction Documents without Landlord’s prior written approval, which approval may be granted or withheld in Landlord’s sole and absolute discretion. Tenant shall be responsible for all Cost and Delay Liability as a result of any such change approved by Landlord.

1.2.5    Delivery Schedule. Landlord shall deliver each Phase of the Premises to Tenant, with each of the Delivery Conditions satisfied, not later than the Outside Delivery Date specified for such Phase in the schedule attached as Exhibit C. If for any reason whatsoever Landlord cannot deliver possession of a specific Phase to Tenant, with each of the Delivery Conditions satisfied, on or before the Outside Delivery Date for such Phase, then this Lease shall not be void or voidable, nor shall Landlord, or Landlord’s Agents be liable to Tenant for any loss or damage resulting therefrom; provided that, Tenant shall not be obligated to pay Base Rent until the Commencement Date and Tenant shall not be obligated to pay Additional Rent for a particular Phase until Tenant has accepted such Phase pursuant to a Handover and Acceptance Certificate.

1.2.6    Tenant’s Access to Phases Prior to Applicable Phase Delivery Date. To the extent reasonably possible, taking into consideration the optimal schedule for installation of the Mesa Equipment in the Premises and the Goods delivery schedule under the MDSA SOW, Landlord will grant Tenant access to each Phase prior to its Applicable Phase Delivery Date as reasonably required for Tenant to perform work within such Phase relating to Tenant’s installation of Tenant’s Property (the “Tenant’s Early Access Work”). Landlord and Tenant will coordinate the performance of Tenant’s Early Access Work with the performance of any ongoing Landlord Work so that each of Tenant’s Early Access Work and the Landlord Work can proceed without material interference from the other and to maintain harmonious labor relations.

1.3    Punch-List Inspection. Approximately ten (10) days prior to Landlord’s delivery of possession of a Phase(s) to Tenant, Landlord and Tenant shall make an inspection of such Phase(s) (the "Punch List Inspection"). During the Punch List Inspection, the parties shall: (a) determine whether the construction and installation of the Applicable Phase Landlord Work for such Phase(s) has been completed, subject to Punch List items, in accordance with the terms of this Lease; and (b) prepare a list of minor work requiring correction or completion by Landlord that will not materially interfere with Tenant using the Phase(s) for the Applicable Phase Purpose (the "Punch List"). Subject to a Force Majeure Event, Tenant Delay, and Tenant’s compliance with the Logistics Plan, Landlord agrees to use reasonable efforts to complete all Punch List items and correct all defects or incomplete items with respect to a delivered Phase, within sixty (60) days after the Applicable Phase Delivery Date.

1.4    Acceptance. Except as otherwise expressly provided herein, by accepting delivery of a Phase(s), evidenced by Tenant’s execution of a Handover and Acceptance Certificate with respect to such Phase(s), Tenant shall be deemed to have accepted such Phase as: (a) suitable for the Applicable Phase Purpose; (b) in good and sanitary operating order, condition and repair with the Applicable Phase Landlord Work complete, subject to any Punch List items; (c) AS-IS, WHERE IS and WITH ALL FAULTS, and (d) without representation or warranty by Landlord as to the condition, use or occupancy which may be made thereof; provided, however, that: (i) Landlord shall, at its sole cost and expense, repair and replace any Construction Defects of which Tenant has notified Landlord in writing within twelve (12) months after the final Applicable Phase Delivery Date for the Premises; (ii) Landlord shall, at no cost to Landlord, assign to Tenant all Transferrable Warranties as the applicable Landlord Work is completed or as soon as is reasonably feasible, and (iii) the foregoing shall not release Landlord from any of its express obligations under this Lease. Tenant acknowledges that: (A) it has been advised by Landlord to satisfy itself with respect to the condition of the Premises and each Phase thereof (including, without limitation, the structural components of the Building and the Building Systems located therein, and the security and environmental aspects thereof) and the present and future suitability of the Premises for the Permitted Use; (B) Tenant has made such inspection and investigation as it deems necessary with reference to such matters and assumes all responsibility therefor as the same relate to Tenant’s use and occupancy of the Premises; and (C) neither Landlord nor any of Landlord’s Agents has made any oral or written representations or warranties with respect to the condition, suitability or fitness of the Premises other than as specifically set forth in this Lease. Further, Tenant expressly disclaims any implied warranty that the Premises are suited for the Permitted Use.

1.5    Handover and Acceptance Certificate. Landlord shall complete and deliver to Tenant for Tenant’s execution: (a) upon the Commencement Date, a certificate in the form attached as Exhibit D to confirm, among other things, the Commencement Date, the Phase(s) (and approximate rentable square feet thereof) delivered on the Commencement Date, the anticipated Expiration Date, and Tenant’s acceptance of the Phase(s) delivered on the Commencement Date; and (b) upon each Applicable Phase Delivery Date, a certificate in the form attached as Exhibit D-1 to confirm, among other things, the Applicable Delivery Date of the Phase(s) delivered pursuant to such certificate, the Phase(s) (and actual number of rentable square feet thereof) delivered on such Applicable Phase Delivery Date, the Current Demised Premises as of such date, and Tenant’s acceptance of the Phase(s) delivered on such Applicable Phase Delivery Date (each such certificate, a “Handover and Acceptance Certificate”). Tenant may reject handover and acceptance of a delivered Phase(s) only if: (i) Tenant can reasonably demonstrate that Landlord has failed to complete (subject to the Punch List items) such Phase(s) in accordance with the terms of this Lease; and (ii) such failure will materially interfere with the Applicable Phase Purpose for such Phase.

1.6    Construction and Dual Occupancy Logistics Plan. The parties acknowledge that Landlord’s undertaking of the Landlord Work in multiple Phases may occur concurrently with Tenant’s possession of, and operations in, one or more of the Phases of the Premises. In order to enable Landlord to substantially complete the Landlord Work in the Premises in accordance with the Phasing Plan, and to enable Tenant to operate in the Current Demised Premises for the Permitted Use, the parties agree to consult in good faith to establish a construction and dual occupancy logistics plan (the “Logistics Plan”) which shall set forth protocols and procedures for the parties during any such dual occupancy period to minimize interruption and interference of the parties’ respective work or operations. The Logistics Plan shall include, without limitation, protocols with respect to utilities shutoff notifications, access and security procedures, location of laydown areas, mitigation of construction noise and dust, onsite monitoring and feedback by Tenant’s authorized representatives with respect to the Landlord Work and a right of entry for Landlord to complete Punch List items. The parties shall use commercially reasonable efforts to negotiate, and mutually agree upon, an approved Logistics Plan on or before the Commencement Date. Once approved, the parties shall comply in good faith with the Logistics Plan.

1.7    Commencement and Expiration of Term. The term of the Lease (“Term”) commenced on the Commencement Date and shall end on the Expiration Date, unless earlier terminated in accordance with the terms of this Lease; provided that, with respect to any Phase of the Premises which was not delivered on the Commencement Date (other than the Phase 1 Premises), the Term of the Lease for such Phase

commenced on such Phase’s Applicable Phase Delivery Date. Landlord shall not be required to seek relief from the automatic stay under Tenant’s chapter 11 case to terminate this Lease and provide notice of the Expiration Date in accordance with the terms hereof.

2.1    Base Rent. Tenant will pay Base Rent to Landlord each Lease Year in the amount of One Hundred Dollars ($100.00), in advance, without demand, deduction or offset commencing on the Commencement Date and thereafter on the first (1^st) day of each Lease Year during the Term. Tenant shall make all Base Rent payments to the Rent Payment Address or at such other address as Landlord may from time to time designate in writing, or, alternatively at Landlord’s election, via electronic funds transfer as directed by Landlord. Tenant shall make all Base Rent payments without Landlord’s previous demand, invoice or notice for payment. The term “Lease Year” means: (a) for the first Lease Year, the period commencing on the Commencement Date and ending on the last day of the twelfth (12^th) full calendar month following the Commencement Date; and (b) thereafter, each period of twelve (12) consecutive months. Notwithstanding that Landlord may deliver possession of the Premises in Phases, the amount of annual Base Rent for each Lease Year during the Term shall be One Hundred Dollars ($100.00) and such amount shall not be affected by adjustments in the square footage of the Premises based on Phased delivery of the Premises.

2.2    Rent Tax. Landlord shall pay all Rent Tax due in connection with this Lease or the payment of Rent hereunder.

2.3    Additional Rent. Notwithstanding any provision of this Lease, Tenant shall have no obligation to pay any additional rent or other costs or expenses associated with the Premises, other than: (1) the actual cost of Utilities under Section 6.1 that Tenant consumes within the Premises during the Term (with no minimum usage charges), (2) amounts for which Tenant is responsible under Section 3.2, and (3) the cost of the insurance that Tenant is required to maintain under Section 10.1. Tenant shall make all payments of Additional Rent without demand, deduction or offset except as expressly provided in this Lease. Tenant shall pay all Additional Rent described in this Lease that is not payable with Base Rent within fifteen (15) Business Days after receiving Landlord’s invoice for such Additional Rent. Tenant shall make all Additional Rent payments to the same location and, except as described in the previous sentence, in the same manner as Tenant’s Base Rent payments. All Additional Rent calculated based on the rentable square footage of the Premises shall be calculated based upon the rentable square footage of the Current Demised Premises for the period in which the invoice for such charges relate.

2.4    Late Payments. If either Landlord or Tenant does not pay any amount due from such party under this Lease within ten (10) Business Days after notice from the other party that the payment is past due, then the defaulting party shall pay to the other party interest on the delinquent payment calculated at the Default Rate from the date when the payment is due through the date the payment is made.

2.5    Independent Obligations. Tenant’s covenant and obligation to pay Rent is independent from any of Landlord’s covenants, obligations, warranties or representations in this Lease.

3.1    Payment of Taxes by Landlord. Except to the extent payable by Tenant pursuant to Section 3.2, Landlord shall pay, prior to delinquency, all Property Taxes for the Premises.

3.2    Payment of Taxes by Tenant. Tenant shall pay, prior to delinquency: (a) all taxes, charges, license fees and or similar fees imposed by reason of the use of the Premises by Tenant, including all applicable sales tax; and (b) all taxes charged against Tenant’s trade fixtures and other personal property (including without limitation the Mesa Equipment and other Tenant’s Property). If any of Tenant’s trade fixtures and other personal property is taxed with the Premises, Tenant shall pay the taxes attributable to Tenant’s trade fixtures and other personal property to the taxing authority.

3.3    Tax Incentive Programs. With respect to any taxes payable by Tenant under this Lease, Tenant shall be permitted to seek, and to receive and retain all benefits from, any and all tax increment financing or other tax incentives or beneficial tax arrangements from Governmental Authorities. Landlord, as the owner of the underlying fee simple interest in the Premises, shall, at no cost to it, cooperate with Tenant to obtain such incentives or arrangements

3.4    Assessments. Notwithstanding anything in this Lease to the contrary, Tenant shall have no obligation to pay any assessments imposed by any state, local or municipal authority in accordance with applicable Laws for public improvements or benefits (including, without limitation, improvement districts and community facilities districts).

4.1    Permitted Use. The Premises may be used solely for the purpose of (a) winding down the business formerly conducted by the Tenant at the Premises in a manner consistent with the Debtors’ Emergency Motion, Pursuant to Bankruptcy Code Sections 105(A) and 363(B), for Entry of Order (I) Authorizing Debtors to Wind Down Operations at Sapphire Manufacturing Facilities and (II) Approving Wind Down Employee Incentive Plan in Connection with Wind Down of Such Operations, dated October 10, 2014 [Docket No. 97], and (b) in furtherance thereof, storing, mothballing, decommissioning, selling and shipping, all at the Tenant’s expense, the ASF Furnaces, Mesa Fabricating Equipment, and the Other Mesa Equipment, and for no other purpose.

Tenant and Tenant’s Agents shall, at Tenant’s expense, faithfully observe and comply with: (a) all applicable Laws pertaining to Tenant’s use of the Premises and Tenant’s obligations under this Lease; and (b) all Private Restrictions pertaining to the Premises or Tenant’s use of the Premises; provided that, Tenant’s obligations under this Lease shall not be materially increased, nor shall Tenant’s rights under this Lease be materially diminished, as a result of the Private Restrictions. Subject to Landlord’s obligations under Section 1.2.2, Tenant will be responsible for obtaining and maintaining all permits required for any of its operations at the Premises.

4.3    Nuisance or Waste. Tenant will not suffer or permit on the Premises any nuisance. Tenant will not permit or commit any waste of the Premises.

Outside storage, including without limitation, storage of trucks and other vehicles, is prohibited without Landlord’s prior written consent, except in the ordinary course of Tenant’s operations at the Premises. Tenant will not use or permit the Premises to be used for any purpose or in any manner that would void Tenant’s or Landlord’s insurance. If any increase in the cost of any insurance on the Premises is caused by Tenant’s use or occupation of the Premises, or because Tenant vacates the Premises, then Tenant shall pay the amount of such increase to Landlord. If Tenant occupies the Premises prior to the Commencement Date, such occupancy shall be subject to all obligations of Tenant under this Lease, other than the obligation to pay Rent.

4.4    Signs. Tenant will not place or permit to be placed in, upon, or about the Premises, the Building or the Land any exterior lights, decorations, flags, pennants, banners, advertisements or notices, or erect or install any signs, windows or door lettering, placards, decorations, or advertising media of any type which can be viewed from the exterior the Premises without obtaining Landlord’s prior written consent, which Landlord may grant or withhold in Landlord’s sole discretion. Any signage shall comply with all applicable Laws.

4.5    OFAC Certification. Each party certifies that it is not: (a) acting directly or indirectly for or on behalf of any person, group, entity, or nation named by any Executive Order or the United States Treasury Department, through its Office of Foreign Assets Control ("OFAC") or otherwise, as a terrorist, "Specially Designated Nation," "Blocked Person," or other banned or blocked person, entity, nation, or transaction pursuant to any law, order, rule or regulation that is enforced or administered by OFAC or another department of the United States government; and (b)  engaged in this transaction (directly or indirectly) on behalf of, or instigating or facilitating this transaction (directly or indirectly) on behalf of, any such person, group, entity or nation.

Tenant will comply with all applicable Laws and regulations enacted to combat bribery and corruption, including the United States Foreign Corrupt Practices Act, the principles of the OECD Convention on Combating Bribery of Foreign Public Officials and any corresponding Laws of all countries where business or services will be conducted or performed pursuant to this Lease (collectively, the “Anti-Corruption Laws”). Tenant and, to the best of Tenant’s knowledge, its subsidiaries and affiliates, have conducted their businesses in compliance with the Anti-Corruption Laws. Tenant will not knowingly in violation of Law or any Landlord policy of which Tenant has been notified, directly or indirectly pay, offer, promise, or give anything of value (including any amounts paid or credited by Landlord to Tenant) to any person or party, to influence any act or decision by such person or party for the purpose of obtaining, retaining, or directing business to Landlord.

4.7    Foreign Trade Zone. Each of Landlord and Tenant shall reasonably cooperate with the other to (a) minimize the adverse tax impact, if any, of the termination of the Foreign Trade Zone or Subzone applicable to the Premises, and (b) avoid such termination, provided that such cooperation shall not require Tenant to incur any material cost or expenditure, or assume any obligation or liability.

4.8    Permitted Contests. Notwithstanding any provision of this Lease to the contrary, Tenant shall not be required to pay, discharge or remove any tax, assessment, levy, fee, rent, charge, lien or encumbrance applicable to the Premises or the use thereof, so long as Tenant is contesting, at its sole cost and expense, the existence, amount or validity thereof, provided that any such contest shall: (a) be by appropriate proceedings conducted in accordance with applicable Law; (b) prevent the collection of or other realization upon the tax, assessment, levy, fee, rent, charge, lien or encumbrance so contested; (c) prevent the sale, forfeiture or loss of the Premises; and (d) not subject Landlord to the risk of any criminal liability or civil penalty, and provided further that any such contest may be conducted only for so long as Tenant, during the pendency of such contest, shall take any and all necessary action to prevent any deterioration or worsening of the condition giving rise to the contest that may result in any personal injury or property damage or cause any of the conditions set forth in the foregoing clauses (a) through (d), inclusive, to no longer be satisfied. Tenant shall indemnify Landlord against any liability or penalty assessed against Landlord by reason of such nonpayment. Upon the termination (after final appeal) of any proceeding relating to any contest by Tenant pursuant to this Section 4.8, Tenant shall immediately pay any amount determined in such proceeding to be due or take any action ordered, and in the event Tenant fails to make such payment or take the action, Landlord shall have the right to make any such payment or take the action on behalf of Tenant and charge Tenant therefor, which shall be due and payable upon Tenant’s receipt of written demand from Landlord.

5.1    Hazardous Materials Disclosure Certificate. Prior to executing the Original Lease, Tenant completed, executed and delivered to Landlord a Hazardous Materials Disclosure Certificate in the form attached as Exhibit E (“Initial Disclosure Certificate”). Tenant covenants, represents and warrants to Landlord that the information on the Initial Disclosure Certificate is true and correct in all material respects and accurately describes, in all material respects, the Hazardous Materials which will be manufactured, treated, used or stored on or about the Premises by Tenant or Tenant’s Agents. Tenant shall, on each anniversary of the Commencement Date, execute and deliver to Landlord an updated Disclosure Certificate (each, an “Updated Disclosure Certificate”) in the form of Exhibit E or in such updated format as Landlord may require.

The term “Hazardous Materials” shall mean and include any substance that is or contains: (a) any “hazardous substance” as now or hereafter defined in § 101(14) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”) (42 U.S.C. § 9601 et seq.) or any regulations promulgated under CERCLA; (b) any “hazardous waste” as now or hereafter defined in the Resource Conservation and Recovery Act, as amended (“RCRA”) (42 U.S.C. § 6901 et seq.) or any regulations promulgated under RCRA; (c) any substance now or hereafter regulated by the Toxic Substances Control Act, as amended (“TSCA”) (15 U.S.C. § 2601 et seq.) or any regulations promulgated under TSCA; (d) petroleum, petroleum by-products, gasoline, diesel fuel, or other petroleum hydrocarbons; (e) asbestos and asbestos-containing material, in any form, whether friable or non-friable; (f) polychlorinated biphenyls; (g) lead and lead-containing materials; or (h) any additional substance, material or waste: (i) the presence of which on or about the Premises requires reporting, investigation or remediation under any Environmental Laws; (ii) which causes or threatens to cause a nuisance on the Premises or any adjacent area or property or poses or threatens to pose a hazard to the health or safety of persons on the Premises or any adjacent area or property; (iii) which, if it emanated or migrated from the Premises, could constitute a trespass, or (iv) which is now or is later classified or considered to be hazardous or toxic under any Environmental Laws. As used in this Lease, the term “Environmental Laws” shall mean and include: (A) CERCLA, RCRA and TSCA; and (B) any other federal, state or local laws, ordinances, statutes, codes, rules, regulations, orders or decrees now or later in effect relating to (1) pollution, (2) the protection or regulation of human health, natural resources or the environment, (3) the treatment, storage or disposal of Hazardous Materials, or (4) the emission, discharge, release or threatened release of Hazardous Materials into the environment.

5.5    Right of Entry and Inspection by Landlord. Subject to the terms of Section 9.6, Landlord will have the right, but not the obligation, to inspect the Premises and surrounding areas for the purpose of determining whether there exists on or about the Premises any Hazardous Material or other condition or activity that is in violation of the requirements of this Lease or of any Environmental Laws. Such inspections may include, but are not limited to, entering the Premises or adjacent property with drill rigs or other machinery for the purpose of obtaining laboratory samples. There shall be no limit on the number of Landlord’s inspections for such purpose during the Term of this Lease. If such inspections reveal the presence of any Hazardous Materials or other condition or activity in violation of the requirements of this Lease, Tenant shall reimburse Landlord for the cost of such inspections within ten (10) days of receipt of a written statement therefor. Tenant will supply to Landlord such historical and operational information regarding the Premises and surrounding areas as may be reasonably requested to facilitate any such inspection and will make available for meetings appropriate personnel having knowledge of such matters. If Tenant intends to vacate the entire Premises prior to the Expiration Date, then Tenant will give Landlord at least sixty (60) days’ prior notice of such intention so that Landlord will have an opportunity to perform such an inspection prior to such vacation. This Section 5.5 shall not create a duty on Landlord’s part to inspect the Premises, or liability on the part of Landlord for Tenant’s use, storage, treatment or disposal of Hazardous Materials, it being understood that Tenant shall be solely responsible for all liability in connection with the same. Landlord shall have the right, but not the obligation, subsequent to an Event of Default, without in any way limiting Landlord’s other rights and remedies under this Lease, to: (a) enter upon the Premises, or to take such other actions as it deems necessary or advisable, to investigate, clean up, remove or remediate any Hazardous Materials or contamination by Hazardous Materials present on, in, at, under, or emanating from, the Premises in violation of Tenant’s obligations under this Lease; and (b) Landlord shall also have the right, at its election, in its own name, to negotiate, defend, approve and appeal, any action taken or order issued by any Governmental Authority with regard to any such Hazardous Materials or contamination by such Hazardous Materials.

5.6    Environmental Conditions Upon Surrender. Without limiting the terms of Section 17.1, Tenant will surrender the Premises to Landlord upon the expiration or earlier termination of this Lease free of debris, waste or Hazardous Materials placed on, about or near the Premises by Tenant or Tenant’s Agents, and in a condition which complies with the terms of this Article 5, including, without limitation, obtaining any closure permits or other governmental permits or approvals related to the closure of any permits or approvals obtained by Tenant for use of Hazardous Materials in or about the Premises that are required under applicable Environmental Laws. If it is determined by Landlord that the condition of all or any portion of the Premises is not in compliance with the provisions of this Lease with respect to Hazardous Materials at the expiration or earlier termination of this Lease, then at Landlord’s sole option, Landlord may require Tenant to hold over possession of the Premises until Tenant can surrender the Premises to Landlord in compliance with the provisions of this Lease, including, without limitation, the conduct or performance of any closures as required by any Environmental Laws. The burden of proof hereunder shall be upon Tenant. Any such holdover by Tenant will be with Landlord’s consent, will not be terminable by Tenant in any event or circumstance and will otherwise be subject to the provisions of Section 15.2.

5.7    Landlord’s Compliance. Except for Tenant’s express obligations under this Article 5, Landlord shall comply with all Environmental Laws applicable to the Premises or any portion thereof.

5.8    Indemnification; Survival. Tenant shall, to the fullest extent allowable under the Laws, indemnify, defend (with counsel reasonably acceptable to Landlord) and hold harmless the Landlord Parties and the Premises from and against any Claims (including, without limitation, loss in value of the Premises, the Building or the Land, liabilities and expenses (including reasonable attorneys’ fees)) sustained by the Landlord Parties or the Premises in any manner relating to or arising out of: (a) any Hazardous Materials placed on or about the Premises by Tenant or Tenant’s Agents; (b) the presence of any Hazardous Materials (excluding a Migratory Release) on or about the Premises as a result of any release or discharge occurring during Tenant’s use or occupancy of the Premises, except to the extent released, discharged or disposed of on, in, at or under as a result of any act or omission of Landlord or Landlord’s Agents; or (c) Tenant’s breach of any provision of this Article 5. Landlord shall, to the fullest extent allowable under the Laws, indemnify, defend (with counsel reasonable acceptable to Tenant) and hold harmless the Tenant Parties from and against any Claims sustained by any of the Tenant Parties in any manner relating to or arising out of: (i) any Hazardous Materials that existed at the Premises as of October 31, 2013; (ii) any Hazardous Materials that are released, discharged or disposed of on, in, at, under, or that emanate from, the Premises as the result of any act or omission of Landlord or Landlord’s Agents; or (iii) Landlord’s breach of any provision of this Article 5. The terms of this Section 5.8 shall survive the expiration or termination of this Lease.

6.1    Utility Services. Except as otherwise provided in this Section 6.1, Tenant shall contract, in its own name, for and pay when due all charges for the cost of all Utilities billed or metered separately to the Premises and/or Tenant, together with all taxes, assessments, charges and penalties added to or included within such cost. Notwithstanding the foregoing, Landlord shall contract in its own name for all electrical service to the Premises, and shall manage the billing of the actual cost of electricity incurred by or on behalf of Tenant in connection with its use and operation of the Premises (such actual costs, without any mark-up or premium whatsoever, and without imposition of any minimum usage charges, the “Electrical Costs”), subject to reimbursement by Tenant for such Electrical Costs in accordance with the terms of this Section 6.1. Landlord will bill Tenant for the Electrical Costs and Tenant shall pay Landlord for the same, as Additional Rent, within thirty (30) days after Landlord’s delivery of a written invoice for the Electrical Costs. If permitted by applicable Laws, Landlord may, at any time and from time to time during the Term, either contract for service from different electrical utility companies (“Alternate Service Providers”) than those providing electrical service on the date hereof (“Utility Service Providers”) or continue to contract for electrical service from the Utility Service Providers; provided, however, that Landlord shall not contract with an Alternate Service Provider without Tenant’s consent, which consent Tenant shall not unreasonably withhold. Any and all costs associated with a change to any Alternate Service Provider shall be paid by Landlord without reimbursement from Tenant. Tenant shall cooperate with Landlord, the Utility Service Providers, and any Alternate Service Providers at all times and, as reasonably necessary, shall allow Landlord, Utility Service Providers, and any Alternate Service Providers reasonable access to all utility lines, feeders, risers, wiring, and any other machinery and/or equipment within the Premises as necessary to provide electrical service to the Premises. In addition, Landlord shall provide the following services to the Premises during the period commencing February 1, 2015 and ending May 31, 2015 (the “SVT Period”), solely for the purpose of enabling Tenant to conduct system verification testing of the ASF Furnaces, and specifically not to operate the ASF Furnaces: compressed air, processed exhaust and house electrical (collectively, the “SVT Systems”). Tenant shall pay Landlord the incremental cost associated with operating the SVT Systems during the SVT Period (including without limitation the cost charged by a duly licensed electrician mutually agreed by Landlord and Tenant in writing, to support the system verification testing) within 30 days after Landlord delivers an invoice and reasonable supporting documentation. Landlord will provide Tenant with cost estimates for operating each SVT System reasonably in advance of the SVT Period in order to enable Tenant to evaluate the anticipated costs of operating each SVT System. Tenant may elect to terminate

service from any one or more SVT System at any time prior to or during the SVT Period, in which case Landlord shall have no further obligation to provide such SVT System. Tenant agrees to prioritize system verification test activities and reasonably cooperate with Landlord to reduce operation and maintenance costs associated with the on-going operation of the Premises. Subject to Tenant’s obligations under Section 7.2, if Landlord is required to make any repair or replacement to any SVT System that is necessary in order to continue to operate such SVT System, then Landlord shall notify Tenant of the need for, and the estimated cost of, such repair or replacement. If Landlord and Tenant are able to agree upon a reasonable allocation of the cost of such repair or replacement, then Tenant shall pay Landlord in advance for Tenant’s agreed-upon portion of the repair or replacement cost and Landlord shall promptly perform such repair or replacement (with Landlord paying the balance of the cost of the repair or replacement) and promptly restore service from the applicable SVT System. If Landlord and Tenant are unable to agree upon a reasonable allocation of the cost of such repair or replacement, then Landlord shall have no obligation to perform such repair or replacement and may cease providing service from the applicable SVT System. Landlord shall have no liability for interruptions of failures of the SVT Systems, except to the extent due to Landlord’s gross negligence or willful misconduct. Tenant shall give Landlord at least 72 hours prior notice of any system verification testing so that Landlord can assure the electrical contractor is sufficiently staffed. Landlord may observe and monitor such testing. Other than the SVT Systems during the SVT Period, Landlord shall not be obligated to provide any of the following systems or services during the Term: processed gas systems (helium and nitrogen), compressed air systems, processed cooling water systems, processed exhaust and ventilation systems, coolant reclaim system, thermal energy storage systems, electrical (other than general building electrical for lighting), cooling tower/chilled water systems (except for ambient air temperature HVAC), reverse osmosis/deionized water system, or control systems (other than as needed by Landlord for mothballing). Landlord shall not be liable for any loss, injury or damage to property caused by or resulting from any variation, interruption, or failure of Utilities due to any cause whatsoever, or from failure to make any repairs or perform any maintenance of the Utilities, except to the extent caused by or arising out of: (a) the negligence or willful misconduct of Landlord or any of Landlord’s Agents; (b) Landlord’s failure to contract for electrical service for the Premises; or (c) Landlord’s failure to reasonably manage the billing and other administrative obligations associated with the Electrical Costs. No temporary interruption or failure of Utilities incident to the making of repairs, alterations, improvements, or due to accident, strike, or conditions or other events shall be deemed an eviction of Tenant or, subject to the terms of Section 18.17, relieve Tenant from any of its obligations hereunder. In no event shall Landlord be liable to Tenant for any damage to the Premises or for any loss, damage or injury to any property on or in the Premises occasioned by bursting, rupture, leakage or overflow of any plumbing or other pipes (including, without limitation, water, steam, and/or refrigerant lines), sprinklers, tanks, drains, drinking fountains or washstands, or other similar cause in, above, upon or about the Premises, except to the extent caused by or arising out of the negligence or willful misconduct of Landlord or any of Landlord’s Agents. As used in this Lease, the term “Utilities” means water, sewer use, sewer discharge fees and permit costs and sewer connection fees, gas, heat, electricity, SVT Systems, refuse pick-up, janitorial service, telephone and all materials and services or other utilities. The terms of this Section 6.1 are subject to the terms of Section 2.3 and Section 7.1 of this Lease. To the extent Landlord consumes any Utilities in connection with the exercise of its rights under Section 9.1 (including, without limitation, a reasonable and equitable allocation of Utilities that are consumed in connection with the operation of the Building’s HVAC systems and any other Building systems that serve the entire Building during any periods when both Landlord and Tenant are in occupancy of the Premises), then, for each such Utility, the party that is invoiced by the applicable utility company shall initially calculated and allocate, reasonably and in good faith, the actual cost of the Utility consumed by Landlord. The party making such calculation and allocation shall provide reasonable documentation to the other party setting forth the amount of the Utility consumed by Landlord and the cost attributable thereto. Landlord and Tenant shall make equitable adjustments of Utility costs to take into account Landlord’s use, and each of Landlord and Tenant shall be responsible for the cost of the Utilities that it consumes.

6.2    Access to Premises. Tenant, its employees, contractors, agents and invitees shall have access to the Premises 24 hours per day, seven days per week, 365 days per year.

6.3    Security Services. Tenant acknowledges and agrees that, while Landlord may engage security personnel to patrol the Premises, Landlord is not providing any security services with respect to the Premises and that Landlord shall not be liable to Tenant for, and Tenant waives any claim against Landlord with respect to, any loss by theft or any other damage suffered or incurred by Tenant in connection with any unauthorized entry into the Premises or any other breach of security with respect to the Premises. Tenant hereby agrees to the exercise by Landlord and Landlord’s Agents, within their sole discretion, of such security measures as, but not limited to, the evacuation of the Premises for cause, suspected cause or for drill purposes, the denial of any access to the Premises and other similarly related actions that it deems necessary to prevent any threat of property damage or bodily injury. If Landlord and Tenant retain the same security firm to perform separate scopes of work, the security staff paid by Landlord shall take direction from the security staff paid by Tenant, but both Landlord and Tenant shall have total access to all information on security activity and all reports shall be shared with both Landlord and Tenant. Recommendations by Tenant’s security staff shall be shared with Landlord and implemented so long as Landlord reasonably approves.

7.1    Landlord’s Obligations. Landlord and Tenant shall reasonably cooperate with each other to ensure that during the Term, the Premises are continuously supplied with all Utilities and services from Building Systems that are reasonably required for Tenant’s use and occupancy of the Premises, and Landlord shall supply the same at its sole cost and expense (and not as a cost or expense that may be charged, directly or indirectly, to Tenant). Landlord, at its sole cost and expense (and not as a cost or expense that may be charged, directly or indirectly, to Tenant), shall (a) perform any mothballing functions it believes to be appropriate in connection with the Building Systems and other Building components, but only if such activities do not unreasonably interfere with Tenant’s use and occupancy of the Premises, and (b) make all repairs and replacements necessary to keep the Structural Elements, Roof Solar Array, Solar Basin and Fuel Cell (if any) in good condition and repair; provided that, Landlord shall not be responsible for any repairs to, or replacements of, the Structural Elements necessary as a result of damage to the Structural Elements, in excess of reasonable wear and tear, caused by Tenant’s use of the Premises, whether for the Permitted Use or otherwise. The term “Structural Elements” means the structural foundation, roof and load-bearing walls of the Building and comparable structural elements of the service areas and loading docks located in the Exterior Areas. Except for Landlord’s obligations under this Lease with respect to Landlord Work and Landlord’s obligations under this Section 7.1, Landlord is not required to furnish any services or facilities, or to make any repairs or Alterations, in, about or to the Premises other than with respect to the Structural Elements. Tenant acknowledges that Landlord is not required to maintain, repair or rebuild all or any part of the Premises or make repairs at the expense of Landlord pursuant to any Laws at any time in effect, except as expressly provided in this Lease.

7.2    Tenant’s Obligations. Notwithstanding any provision of this Lease, Tenant shall have no obligation to (a) make any repair, replacement, or improvement to the Premises, (b) perform any maintenance at or with respect to the Premises, or (c) perform any decommissioning or “mothballing” of any portion of the Premises or any Building System, except that Tenant shall: (i) repair any damage that any Tenant Party causes to the Premises, except for any loss or damage waived under Section 10.3 of this Lease, and (ii) Tenant shall comply with the terms of Article 5 of this Lease. Notwithstanding Section 17.1, but subject to Section 10.3, if the need for any expenditure by Landlord for repair, replacement or maintenance at the Premises is attributable to Tenant’s negligence, then Tenant shall reimburse Landlord for the cost of such necessary repair or replacement.

7.3    Alterations Required by Laws. Landlord shall be responsible for any changes or modifications to the Structural Elements that may be required by applicable Laws.

8.1    Landlord Consent Requirements. From and after the Effective Date, Tenant shall not make any: (a) Structural Alteration without the prior written consent of Landlord, which consent may be granted or withheld in Landlord’s sole discretion; or (b) System Alteration without the prior written consent of Landlord, which consent shall not be unreasonably withheld. Ownership of the Mesa Equipment and related equipment is subject to the Amended Settlement Agreement and at the expiration or earlier termination of this Lease, unless otherwise agreed in writing by Landlord, Tenant shall either remove all Mesa Equipment and related equipment owned by one or more GTAT Parties from the Premises or move only the ASF Furnaces to the Storage Space.

8.2    Installation of Tenant Alterations. Any Alteration to the Premises approved by Landlord (under Section 8.1) and made by Tenant shall be at Tenant’s sole cost and expense, in compliance with all applicable Laws and all reasonable requirements of any insurer providing coverage for the Premises or any part thereof. Tenant shall obtain, in advance, and furnish to Landlord any necessary permits for such Alterations, together with proof of Tenant’s (or its contractor’s) builder’s “all risk” insurance in an amount at least equal to the replacement value of the Alterations and liability insurance as required in the attached Exhibit F-1, Tenant will diligently and continuously pursue the Alterations to completion. Landlord may monitor construction of the Alterations and Tenant shall reimburse Landlord for its reasonable costs (including, without limitation, the reasonable costs of any construction manager retained by Landlord) in reviewing plans and documents and in monitoring construction.

8.3    Ownership. Subject to Section 8.8 and the Amended Settlement Agreement, all Alterations Tenant makes or installs (excluding installation of any of Tenant’s Property) shall become the property of Landlord and a part of the Premises at the expiration or earlier termination of the Term, and Tenant shall surrender the Alterations to Landlord upon expiration or earlier termination of this Lease.  

8.4    Liens. Tenant shall be responsible for all costs and charges for any work done by or for Tenant on or about the Premises or in connection with Tenant’s occupancy thereof, and shall keep the Premises free from any mechanics’, materialmen’s, designers’ or other liens arising out of any work performed, materials furnished or obligations incurred by or for Tenant or any Person claiming by, through or under Tenant (“Liens”). If any such Lien is filed or recorded against Landlord’s interest in the Premises and Tenant, within thirty (30) days after receipt of written notice of such filing or recording, does not release the same of record or provide a bond or other surety satisfactory to Landlord protecting Landlord and the Premises against such Lien, Landlord may, without waiving its rights and remedies based upon such breach by Tenant and without releasing Tenant from any obligation under this Lease, upon notice to Tenant, cause such Lien to be released by any means Landlord deems proper, including, but not limited to, paying the claim giving rise to the Lien or posting security to cause the discharge of the Lien. Tenant shall reimburse Landlord, as Additional Rent, for all amounts Landlord pays (including, without limitation, reasonable attorneys’ fees and costs).

8.5    Indemnification. Tenant shall, to the fullest extent allowable under the Laws, indemnify, defend (with counsel reasonably acceptable to Landlord) and hold harmless the Landlord Parties and the Premises from and against any Liens or Claims in any manner relating to or arising out of any Alterations or any other work performed, materials furnished or obligations in connection with the same incurred by or for Tenant or any Person claiming by, through or under Tenant.

8.6    Documentation. Upon completion of any Structural Alterations, at Landlord’s request, Tenant shall promptly provide Landlord with: (a) an architect’s certificate certifying the Structural Alterations have been completed in conformity with the plans and specifications; (b) a certificate of occupancy (if the alterations are of such a nature as would require the issuance of a certificate of occupancy under applicable Laws); (c) a complete set of as-built plans and specifications; and (d) any other documents or information reasonably requested by Landlord.

8.7    Cooperation. Landlord shall cooperate with Tenant in the application for any permit or authorization required by Laws provided there shall be no cost, liability, obligation or expense to Landlord.

8.8    Tenant’s Property. The terms of this Section 8.8 are and shall remain subject to the Amended Settlement Agreement and the order of the Bankruptcy Court approving the Amended Settlement Agreement. Notwithstanding any provision of this Lease to the contrary but subject to the Amended Settlement Agreement, all of the Tenant’s Property shall remain the property of the applicable member of the Tenant Group. Subject to the Amended Settlement Agreement (and the removal procedures set forth in the Order Under Bankruptcy Code Sections 105(a), 327(a), 328(a), 330(a) and 363 and Bankruptcy Rules 2002, 2014, 2016, and 6004(h) for Entry of Order (I) Approving Procedures to Sell, Lease, or Otherwise Dispose of Excess Assets, (II) Authorizing Retention of Brokers and Other Sales Agents, and (III) Waiving Requirements of Local Bankruptcy Rule 2016-1, ECF No. 811), each member of the Tenant Group shall have the right, at any time and from time to time during the Term, to maintain, repair, replace, remove, and finance any and all of its Tenant’s Property. At the expiration of the Term or earlier termination of this Lease, Tenant shall (or shall cause each member of the Tenant Group to) remove all of the Tenant’s Property from the Premises unless either: (a) Tenant is permitted to leave such Tenant’s Property at the Premises pursuant to the terms of Section 17.1; or (b) Landlord gives Tenant a written waiver for same. At any time that a member of the Tenant Group removes any of its Tenant’s Property, Tenant shall (or shall cause such member of the Tenant Group to) promptly repair the Premises as a result of any damage to, or destruction of, the Premises caused by such removal. Tenant will indemnify Landlord and Landlord’s Parties against, and hold Landlord and the Landlord Parties harmless from, any claims, loss, injury, liability, or damages (including reasonable attorneys' fees) incurred by such party as a result of any member of the Tenant Group entering the Premises to remove any of Tenant’s Property from the Premises. Subject to the Amended Settlement Agreement, Tenant (or any other applicable GTAT Party) shall have the right to grant a lien on and a security interest in all of Tenant’s Property and any other assets and personal property of Tenant located at the Premises in favor of any creditor of Tenant (each a “Secured Party”) and such Secured Party shall be permitted to foreclose upon such interest, all without Landlord’s consent. Subject to the Amended Settlement Agreement, Landlord waives any and all security interests, liens, claims or other similar rights (including rights of levy or distraint for rent on or in Tenant’s assets or personal property) with respect to Tenant’s Property and any other assets or personal property of Tenant located at the Premises. Subject to the Amended Settlement Agreement, upon the request of Tenant, Landlord shall execute an agreement: (i) confirming Landlord’s consent to the Secured Party’s lien or security interest and Landlord’s waiver as described above; and (ii) providing the Secured Party with the right to access any and all collateral located at the Premises, which agreement shall be in form and substance reasonably satisfactory to Landlord and such Secured Party.

9.1    Landlord’s Entry. Subject to the terms of Section 9.6, Landlord, its affiliates and their respective designees shall have full and unrestricted access to the Premises at all times, with no prior notice to or consent from Tenant; provided that Tenant, at its cost, may observe Landlord's actions on the Premises. Tenant will supply Landlord, its affiliates and their respective designees with access cards and make other arrangements in order to provide this access. No such entry shall be construed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction of Tenant from the Premises. Landlord may temporarily close entrances, doors, corridors, elevators or other facilities without liability to Tenant by reason of such closure in the case of any such emergency. Landlord, its affiliates and their respective designees shall have unrestricted access to, and use of, an existing office in the Premises that Landlord’s employees and Ch2m Hill used prior to the Effective Date or are using as of the Effective Date.

9.2    Assignment of Warranties, Guaranties, Permits, Contracts and Documents. Landlord shall use commercially reasonable efforts to ensure that all guarantees, warranties and the like that relate to any of the Landlord Work are assignable to Tenant. At the end of the Term, Tenant shall assign (or cause the applicable member of the Tenant Group to assign) to Landlord in writing pursuant to a mutually agreeable

assignment and assumption agreement to the full extent assignable: (a) warranties and guarantees relating to the Building and Improvements which are then in effect, and relating to the Mesa Equipment to the extent the Mesa Equipment has or will become the property of Landlord pursuant to the Amended Settlement Agreement; (b) licenses and governmental approvals and permits relating to the Premises and the Building that are held by Tenant; (c) as-built plans, specifications, drawings and architectural and engineering studies relating to the Building; and (d) if requested by Landlord, operations, supply, maintenance, repair, service and other contracts relating to maintenance and operation of the Premises and the Building, but only if and to the extent Tenant and its affiliates are released from all obligations and liabilities with respect to such contracts that first arise after the effective date of such assignment.

9.3    Right to Cure. In addition to the rights set forth in Section 15.7, if either Landlord or Tenant defaults, beyond any applicable notice and cure period, in the performance of any obligation under Article 7 of this Lease and such default may have a material adverse impact on the operation of the Premises for the Permitted Use or the value of the Premises, then the other party may, but is not obligated to, perform any such obligation on the defaulting party’s part without waiving any rights based upon such default and without releasing the defaulting party from any obligations hereunder. The defaulting party shall pay to the curing party, within fifteen (15) Business Days after delivery by the curing party to the defaulting party of statements therefor, sums equal to expenditures reasonably made and obligations reasonably incurred by the curing party in connection with the remedying of the defaulting party’s defaults, and such amount due shall bear interest at the Default Rate until paid in full. Such obligations survive the termination or expiration of this Lease.

9.4    Power Source Area. Subject to the terms of Section 9.6, Landlord may elect, in Landlord’s sole and absolute discretion to install a fuel-cell system on the Premises to provide electrical service to the Premises (the “Fuel Cell”); provided that: (a) the size and location of the Fuel Cell shall be designed in consultation with Tenant to minimize interference to Tenant and Tenant’s use of the Premises for the Permitted Use; (b) Landlord shall bear all costs and expenses of the Fuel Cell (except for costs or expense resulting or relating to Tenant’s negligence or willful misconduct); and (c) Landlord shall install and maintain the Fuel Cell in compliance with all applicable Laws.

9.5    Intentionally Omitted.

9.6    Indemnification. In addition to Landlord’s other indemnification obligations in this Lease, Landlord shall, to the fullest extent allowable under the Laws, indemnify, defend (with counsel reasonably acceptable to Tenant) and hold harmless the Tenant Parties from and against all Claims in any manner relating to or arising out of: (a) any accident, injury, occurrence or damage in, about or on the Premises in any way related to the Roof Solar Array, the Solar Basin, or the Fuel Cell or the operation thereof (except to the extent such Claims arise from or in connection with any negligence or willful misconduct of Tenant or Tenant’s Agents); or (b) any personal injury or property damage caused in or about the Premises by Landlord or Landlord’s Agents gross negligence or willful misconduct in its exercise of any right under this Lease to enter the Premises.

9.7    Excluded Infrastructure. Notwithstanding any other provision of this Lease, but subject to Tenant’s agreements under Section 11.1.2 with respect to the negligence or willful misconduct of Tenant or Tenant’s Agents, Tenant shall have no obligation to: (a) repair, maintain, replace, alter or improve any or all of the Excluded Infrastructure; (b) obtain permits, licenses or other approvals from Governmental Authorities with respect to any or all of the Excluded Infrastructure or the operation thereof; or (c) to otherwise comply with Laws (including, without limitation, Environmental Laws) applicable to any or all of the Excluded Infrastructure or the operation thereof, or to conditions that may arise in connection therewith. To the extent any Excluded Infrastructure has not been installed at the Premises as of the Effective Date, then the size and location of such Excluded Infrastructure shall be designed in consultation with Tenant to minimize interference to Tenant and Tenant’s use of the Premises for the Permitted Use.

10.1    Tenant's Insurance Obligations. Tenant shall, at Tenant’s sole cost and expense, at all times during the Term, maintain the insurance described in the attached Exhibit F-1.

10.1.1    Evidence of Insurance. Upon the Effective Date, and upon renewal or replacement of coverage, Tenant shall deliver to Landlord certificates of insurance and any additional documentation reasonably requested by Landlord (including, without limitation, policy endorsements) to assure compliance with this Section 10.1. If any of the insurance policies required by this Section 10.1 are cancelled prior to the stated expiration date, Tenant shall promptly replace such coverage so that no lapse in insurance occurs.

10.1.2    Copies and Additional Information. Tenant shall provide to Landlord upon request certified copies of all policies and endorsements. If Tenant’s insurance carrier will not provide certified copies, each copy of a policy shall include a copy of all endorsements and shall be accompanied by a letter from Tenant’s insurance broker or Tenant’s authorized agent stating that Tenant’s insurance carrier will not provide certified copies of insurance policies and endorsements and that the enclosed copy of the policy and endorsements is a true, correct and complete copy of the respective insurance policy and all endorsements to the best of the broker’s or authorized agent’s knowledge. In addition, Tenant agrees to reasonably cooperate with Landlord in obtaining any and all information demonstrating Tenant is in compliance with the insurance requirements of this Section 10.1.

10.1.3    Claims Reporting. In the event that Tenant reports any claims to its insurers issuing the coverage required under this Lease, Tenant shall advise Landlord of the same. Tenant shall diligently pursue coverage of claims under all such insurance policies and keep Landlord advised of any claim denials, whether partial denials or full denials, and the basis for the same.

10.1.4    Modification of Insurance Requirements. From time to time during the Term, but not more often than once in any five (5) year period, Landlord may require that the types of insurance specified herein be modified as to the insurance amounts and/or coverages provided, but only to the extent then reasonable and customary for tenants of similar properties with similar uses.

10.1.5    Tenant's Failure to Insure. Notwithstanding any contrary language in this Lease and any notice and cure rights this Lease provides Tenant, if Tenant fails to provide Landlord with evidence of insurance as required under Section 10.1.1, and provided that such failure continues for at least ten (10) Business Days following written notice thereof to Tenant from Landlord, Landlord may assume that Tenant is not maintaining the insurance required under Section 10.1. In such event, and without further notice or demand to Tenant, Landlord may, but is not obligated to, obtain such insurance for Landlord's benefit. Landlord’s exercise of this right shall not cure Tenant’s breach or waive any right the Landlord has with respect to Tenant’s default. Upon demand, Tenant shall pay to Landlord, as Additional Rent, all reasonable costs and expenses Landlord incurs in obtaining such insurance, and such amount due shall bear interest at the Default Rate until paid in full.

10.2    Landlord's Insurance Obligations. Landlord shall, at Landlord’s sole cost and expense, at all times during the Term maintain the insurance described in the attached Exhibit F-2. Landlord in its sole discretion may elect to self-insure any or all coverage set for in Exhibit F-2.

10.3    Waiver of Subrogation Under Property Insurance Policies. Notwithstanding any other provision of this Lease, but subject to the terms of Section 10.4 and as long as the insurance is not invalidated thereby, Landlord and Tenant hereby waive, and shall cause their respective property insurers to waive, release and discharge the other party, its employees, and agents and their insurers for any loss or damage

with respect to the Premises, or any contents thereof (including the Mesa Equipment and other Tenant’s Property), which loss or damage is covered by the property insurance required by this Lease (whether or not the property insurance is actually maintained by the party suffering the loss or damage and regardless of whether or not the loss or damage falls within a deductible or other self-insured mechanism), and Landlord and Tenant, respectively, will look only to its insurance coverage (regardless of whether Landlord or Tenant maintains any such coverage) in the event of any such Claim.

10.4    Certain Conduct Resulting in Insurance Costs. If the recklessness or willful misconduct of either Landlord or Tenant (which shall apply only to the extent that conduct of any person or entity may be imputed, as a matter of law, to such party) causes property damage to the other party and such damage is covered by insurance maintained or which is required to be maintained under this Lease, then the party causing such damage shall be responsible for paying the following amounts: (a) the deductible attributable to such insured event, not to exceed $2,000,000 per event of loss (and, if the loss is not insured, then an amount not to exceed $2,000,000 per event of loss); and (b) any increase in the property insurance premiums for or allocable to the Premises or the Tenant’s Property maintained within the Premises following the insured event for the balance of the Term.

11.1    Release and Indemnification.

11.1.1    Waiver of Liability/Assumption of Risk. Tenant agrees that its use and occupancy of the Premises is at its own risk and, to the full extent permitted by Law, hereby releases Landlord and the Landlord Parties from all claims for any damage or injury except to the extent of any Excluded Liability. To the fullest extent allowed by law except to the extent of any Excluded Liability, Landlord shall not be responsible or liable for any property damage, bodily injury or injury to the business (or loss of income therefrom), goods, wares, merchandise or other property of Tenant in or about the Premises, whether such damage or injury is caused by or results from: (a) fire, steam, electricity, water, gas or rain; (b) the breakage, leakage, obstruction or other defects of pipes, sprinklers, wires, appliances, plumbing, air conditioning or lighting fixtures or any other cause; (c) conditions arising in or about the Premises or from other sources or places; or (d) any act or omission of any other party. Landlord shall not be liable for any such damage or injury, even though the cause of, or the means of repairing, such damage or injury are not accessible to Tenant. Tenant agrees that any employee or agent to whom the Premises or any part thereof shall be entrusted by or on behalf of Tenant shall be acting as Tenant’s agent with respect to the Premises or any part thereof, and neither Landlord nor any other Landlord Party shall be liable for any loss of or damage to the Premises or any part thereof. The term “Excluded Liability” means Landlord’s liability under this Lease to the extent resulting from or relating to: (i) the negligence or willful misconduct of Landlord or Landlord’s Agents; and (ii) Landlord’s breach of this Lease (including Landlord’s failure to perform Landlord’s obligations hereunder).

11.1.2    Indemnification by Tenant. In addition to Tenant’s other indemnification obligations in this Lease (including without limitation in Sections 4.5, 4.8, 5.8, 8.5, 8.8, 15.4 and 18.10), but subject to Landlord’s agreements in Section 11.1.3, Tenant shall, to the fullest extent allowable under the Laws, indemnify, defend (with counsel reasonably acceptable to Landlord) and hold harmless the Landlord Parties from and against all Claims in any manner relating to or arising out of: (a) any negligence or willful misconduct of Tenant or Tenant’s Agents; (b) any accident, injury, occurrence or damage in, about or on the Premises; or (c) any use or occupancy of the Premises or any part thereof by the Tenant Parties. In the event that Landlord or Landlord’s Agents caused or contributed to cause the Claims for which indemnity is sought under this Section 11.1.2, the damages and expenses (including, without limitation, reasonable attorneys’ fees) shall be allocated, or reallocated, as the case may be, between the indemnified and the indemnifying party, in such proportion as appropriately reflects the relative fault of the two parties, and the liability of the indemnifying party shall be proportionately reduced. The indemnity provisions of this Section shall survive termination or expiration of this Lease.

11.1.3    Indemnification by Landlord. Subject to Tenant’s waivers, releases and agreements in this Article 11 and elsewhere in this Lease, and subject to Tenant’s agreements in Section 11.1.2 and the qualifications with reference to the use of the term “negligence” set forth below, in addition to Landlord’s other indemnification obligations in this Lease (including without limitation in Sections 4.5, 5.8, 9.6 and 18.10) Landlord shall, to the fullest extent allowable under the Laws, indemnify, defend and hold harmless Tenant from and against all Claims brought against Tenant by third parties to the extent caused by or resulting from the negligence or willful misconduct of Landlord or any of Landlord’s Agents. For purposes of this indemnification obligation, the term “negligence” shall not include Landlord’s failure to act in respect of matters which are or were the obligation of Tenant under this Lease, including, without limitation, Claims caused by, incurred or resulting from Tenant’s operations or by Tenant’s use and occupancy of the Premises, whether relating to its original design or construction, latent defects, alteration, maintenance, or use by Tenant or any person thereon, including, without limitation, supervision or otherwise, or from any breach of, default under, or failure to perform any term or provision of this Lease by Tenant or Tenant’s Agents. In the event that Tenant or Tenant’s Agents caused or contributed to cause the Claims for which indemnity is sought under this Section 11.1.3, the damages and expenses (including, without limitation, reasonable attorneys’ fees) shall be allocated, or reallocated, as the case may be, between the indemnified and the indemnifying party, in such proportion as appropriately reflects the relative fault of the two parties, and the liability of the indemnifying party shall be proportionately reduced. The indemnity provisions in this Section shall survive termination or expiration of this Lease.

11.1.4    Claim Procedure. The indemnification obligations of Landlord and Tenant under this Lease are conditioned on the indemnified party promptly notifying the indemnifying party in writing after any of the indemnified parties receives notice of a claim or loss for which indemnification is or may be sought under this Lease.  Failure to provide such notice will relieve the indemnifying party of its indemnity obligations only to the extent that such failure actually prejudices the indemnifying party.  The indemnifying party will have the right to control, in a manner not adverse to the indemnified parties, the defense and settlement of any claims.  The indemnified parties may employ counsel, at their own expense, with respect to any such claim (provided that if counsel is employed due to a conflict of interest or because the indemnifying party does not assume control of the defense, the indemnifying party will bear such expense).  The indemnifying party will not admit liability or enter into any settlement of a claim that adversely affects the indemnified parties’ rights or interests without the indemnified parties’ prior written approval, which shall not be unreasonably withheld or delayed.

12.1    Notification. Tenant shall give Landlord written notice promptly after any damage or destruction to the Premises from a fire or other casualty which damage or destruction could have a material adverse impact on operation of the Premises for the Permitted Use or the value of the Premises. Tenant’s notice shall provide a general description of the nature and extent of the damage or destruction, and shall include copies of any documents or notices received in connection with the same. Thereafter, Tenant shall promptly send Landlord copies of all notices, correspondence and pleadings relating to any such casualty.

12.2    Restoration. Unless this Lease is terminated by Landlord or Tenant pursuant to Section 12.3, if the Premises is damaged or destroyed by any fire or other casualty, then: (a) Landlord shall, at its sole expense, as promptly as practicable after such fire or other casualty, repair, reconstruct or replace the Premises (other than Tenant’s Alterations) and the Electrical Substation (or Landlord shall cause the applicable utility to repair, reconstruct or replace the Electrical Substation) to as nearly as possible the same condition in which they existed prior to such damage or destruction, and (b) Tenant shall, at its sole expense, as promptly as practicable after Landlord has completed its restoration work, repair, reconstruct or replace such portion of Tenant’s Alterations that were not constructed by Landlord to as nearly as possible the same

condition in which they existed prior to such damage or destruction. The work to be performed by Landlord and Tenant pursuant to this Section 12.2 is referred to herein as the “Restoration Work.”

12.3    Termination.

12.3.1    If the Premises is damaged or destroyed by fire or other casualty, an independent architect or engineer shall, at Landlord’s sole cost and expense, reasonably estimate the period of time required for Landlord and Tenant to perform the Restoration Work. Such architect or engineer shall provide a detailed written statement of such estimate to Landlord and Tenant within thirty (30) days after the date of such destruction or damage (“Landlord’s Restoration Estimate”). If such architect or engineer determines that the Restoration Work cannot reasonably be expected to be completed by November 30, 2015, then Landlord or Tenant may terminate this Lease by giving written notice to the other party within thirty (30) days after such determination by Landlord’s architect or engineer.

12.3.2    If the Premises is destroyed or damaged by fire or other cause that is not insurable under a fire, extended coverage and so-called “all-risk” insurance policy with coverage against vandalism and malicious conduct, and such destruction or damage renders at least twenty-five percent (25%) of the Premises untenantable, then Landlord may terminate this Lease by giving written notice to Tenant within thirty (30) days after the date of such fire or other casualty.

12.3.3    If all or any portion of the Premises is damaged by fire or other casualty, and neither Landlord nor Tenant elects to terminate this Lease pursuant to the foregoing provisions of this Section 12.3, and Landlord shall fail to substantially complete the portion of the Restoration Work for which it is responsible within the period estimated in Landlord’s Restoration Estimate, subject to a Force Majeure Event and Tenant Delays, then Tenant may deliver written notice to Landlord (the “Casualty Termination Notice”) of Tenant’s intent to terminate the Lease, provided that, Tenant shall deliver to Landlord such Casualty Termination Notice within thirty (30) days after the expiration of the period set forth in Landlord’s Restoration Estimate. Tenant’s termination of this Lease pursuant to this Section 12.3.3 shall be effective sixty (60) days after Landlord’s receipt of the Casualty Termination Notice; provided, however if Tenant fails to deliver the Casualty Termination Notice within the required 30-day period, or if Tenant timely delivers to Landlord the Casualty Termination Notice and Landlord substantially completes the portion of the Restoration Work for which it is responsible prior to the expiration of the 60-day notice period, subject to a Force Majeure Event and Tenant Delays, then the Lease shall continue in existence and any Casualty Termination Notice so delivered shall be deemed null and void. If Landlord fails to substantially complete the portion of the Restoration Work for which it is responsible within sixty (60) days after Landlord receives the Casualty Termination Notice, then this Lease shall terminate on the sixty-first (61^st) day after Landlord’s receipt of the Casualty Termination Notice.

12.4    Rent Abatement. In the event of repair and restoration as herein provided, the monthly installments of Base Rent shall be abated proportionately corresponding to the time during which, and to the portion of the floor area of the Premises of which, Tenant is deprived on account of such repair or restoration, as reasonably determined by Landlord; provided that, Tenant shall not be entitled to such abatement to the extent that such damage or destruction resulted from the acts or inaction of Tenant or Tenant’s Agents. Except as expressly provided in the immediately preceding sentence with respect to abatement of Base Rent, Tenant shall have no claim against Landlord for, and hereby releases Landlord and Landlord’s Agents from responsibility for and waives its entire claim of recovery for any cost, loss or expense suffered or incurred by Tenant as a result of any damage to or destruction of the Premises or the Building or the repair or restoration thereof, including, without limitation, any cost, loss or expense resulting from any loss of use of the whole or any part of the Premises and/or any inconvenience or annoyance occasioned by such damage, repair or restoration. To the extent permitted by the Laws, Tenant waives the benefits of any Law that provides Tenant any abatement or termination rights by virtue of a casualty not specifically described in this Section 12.4. Subject to the Amended Settlement Agreement, neither Landlord nor any mortgagee shall have any right to, or interest in, any proceeds of insurance relating to Tenant’s Property.

13.1    If twenty-five percent (25%) or more of either the Premises or the Building is taken for any public or quasi-public purpose by any Governmental Authority, by exercise of the right of appropriation, inverse condemnation, condemnation or eminent domain, or sold to prevent such taking (each such event being referred to as a “Condemnation”), Landlord may, at its option, terminate this Lease as of the date title vests in the condemning party. If twenty‑five percent (25%) or more of the Premises is taken and if the Premises remaining after such Condemnation and any repairs by Landlord would be untenantable for the conduct of Tenant’s business operations, Tenant shall have the right to terminate this Lease as of the date title vests in the condemning party. If either party elects to terminate this Lease as provided herein, such election shall be made by written notice to the other party given within thirty (30) days after the nature and extent of such Condemnation have been finally determined. If neither Landlord nor Tenant elects to terminate this Lease to the extent permitted above, Landlord shall promptly proceed to restore the Premises (other than Tenant’s Alterations), to the extent of any Condemnation award received by Landlord, to substantially the same condition as existed prior to such Condemnation, allowing for the reasonable effects of such Condemnation. A proportionate abatement shall be made to the Base Rent corresponding to the time during which, and to the portion of the floor area of the Premises (adjusted for any increase thereto resulting from any reconstruction) of which, Tenant is deprived on account of such Condemnation and restoration, as reasonably determined by Landlord. Except as expressly provided in the immediately preceding sentence with respect to abatement of Base Rent and as provided below in Section 13.2, Tenant shall have no claim against Landlord for, and hereby releases Landlord and Landlord’s Agents from responsibility for and waives its entire claim of recovery for any cost, loss or expense suffered or incurred by Tenant as a result of any Condemnation or the repair or restoration of the Premises following such Condemnation, including, without limitation, any cost, loss or expense resulting from any loss of use of the whole or any part of the Premises and/or any inconvenience or annoyance occasioned by such Condemnation, repair or restoration.

13.2    Tenant shall have the right to participate with Landlord and to be a party in any condemnation proceeding. Landlord and Tenant shall cooperate to maximize the total award made by the Condemnation authority. Landlord shall be entitled to any and all compensation, damages, income, rent, awards, or any interest therein whatsoever which may be paid or made in connection with any Condemnation, and Tenant shall have no claim against Landlord for the value of any unexpired term of this Lease or otherwise; provided that, Tenant shall be entitled to receive any award separately allocated by the condemning authority to Tenant for either or both of: (a) Tenant’s relocation expenses; and (b) the value of Tenant’s Property (specifically excluding fixtures, Alterations and other components of the Premises which under this Lease or by law are or at the expiration of the Term will become the property of Landlord), provided that such award does not reduce any award otherwise allocable or payable to Landlord.

13.3    The provisions of this Article 13 are Tenant’s sole and exclusive rights and remedies in the event of a Condemnation. To the extent permitted by the Laws, Tenant waives the benefits of any Law that provides Tenant any abatement or termination rights or any right to receive any payment or award (by virtue of a Condemnation) not specifically described in this Article 13.

14.1    Restriction on Transfers. Except as provided below, this Lease and the rights and obligations of Tenant under this Lease are personal to GTAT Corporation, a Delaware corporation (“GTAT”), and GTAT may not Transfer this Lease or any right or obligation under this Lease, without the prior written consent of Landlord which may be granted or withheld in Landlord’s sole and absolute discretion. No Transfer shall release Tenant from any liability or obligation under this Lease and Tenant shall remain liable to Landlord

after such a Transfer as a principal and not as a surety. Any purported or attempted Transfer, in whole or in part, without Landlord’s consent will be null and void and will constitute an Event of Default.  Tenant may not allow a change of control of Tenant without Landlord’s prior written consent, which consent, in each instance, will be in Landlord’s sole and absolute discretion. For purposes of this provision "change of control of Tenant" shall not include a change in ownership that occurs solely through the distribution provisions of a confirmed plan of reorganization to creditors of Tenant or its affiliates pursuant to chapter 11 of title 11 of the United States Code, unless such confirmed plan results in any one entity or “group” (as defined in section 13(d) of the Exchange Act) of entities working together, which (a) entity is a competitor of Apple Inc. (“Apple”) acting in the consumer electronics business, or (b) group of entities working together includes one or more entities that are competitors of Apple acting in the consumer electronics business (which competitor entities hold in the aggregate, through share ownership or contractual arrangements or otherwise, more than 50% of the total voting power in such group), that results in each case of (a) or (b) in such entity or group obtaining control of Tenant. For purposes of this clause “control” means the entity or group possesses, directly or indirectly, the power to direct or cause the direction of the management policies of Tenant, whether through ownership of voting securities, an interest in registered capital, by contract or otherwise.

14.2    Costs. Tenant shall pay to Landlord, as Additional Rent, all reasonable costs and expenses Landlord incurs in connection with any Transfer, including, without limitation, reasonable attorneys’ fees and costs, regardless of whether Landlord consents to the Transfer.

14.3    Permitted Subleases. Provided Tenant shall provide Landlord prior written notice, and verification of Tenant’s relationship to the Permitted Sublessee, Tenant may assign this Lease or sublease all or any portion of the Premises to any Person that is 100% owned and controlled by GTAT (“Permitted Sublessee”), but any such assignment or sublease shall not release GTAT from any of its obligations or liabilities under this Lease.

15.1    Events of Default. The occurrence of any of the following constitutes an “Event of Default” by Tenant under this Lease:

15.1.1    Failure to Pay Rent. Tenant fails to pay Base Rent or any Additional Rent as and when due and such failure continues for five (5) Business Days after Landlord delivers written notice thereof to Tenant except that Tenant shall not be entitled to notice more than twice in any consecutive twelve (12) month period and the failure to timely pay Base Rent or any other Additional Rent when due on the third and any subsequent instance of late payment in a consecutive twelve (12) month period shall be an immediate default.

15.1.2    Failure to Observe or Perform. Tenant fails to observe or otherwise breaches or fails to perform any of the other provisions of this Lease to be observed or performed by Tenant under this Lease and such failure continues for a period of thirty (30) days after Landlord delivers written notice to Tenant of Tenant’s breach or failure; provided that if Tenant cannot reasonably cure its breach or failure within a 30-day period, Tenant’s breach or failure is not an Event of Default if Tenant commences to cure its breach or failure within the 30-day period and thereafter diligently pursues the cure to completion.

15.1.3    Other Defaults. (a) Tenant makes a general assignment or general arrangement for the benefit of creditors; (b) a petition for adjudication of bankruptcy or for reorganization or rearrangement is filed by Tenant; (c) a petition for adjudication of bankruptcy or for reorganization or rearrangement is filed against Tenant and is not dismissed within one hundred twenty (120) days; (d) a trustee or receiver is appointed to take possession of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this Lease and possession is not restored to Tenant within one hundred twenty (120) days; or (e) substantially all of Tenant’s assets, substantially all of Tenant’s assets located at the Premises, or Tenant’s

interest in this Lease is subjected to attachment, execution or other judicial seizure not discharged within sixty (60) days (collectively, an “Insolvency”). For the avoidance of doubt, “Insolvency” shall exclude the chapter 11 cases of the GTAT Parties currently pending before the United States Bankruptcy Court for the District of New Hampshire, Case No. 14-11916-HJB). If a court of competent jurisdiction determines that any act described in this Section 15.1.3 does not constitute an Event of Default, and the court appoints a trustee to take possession of the Premises (or if Tenant remains a debtor in possession of the Premises) and such trustee or Tenant Transfers Tenant’s interest hereunder, then Landlord is entitled to receive, as Additional Rent, the amount by which the Rent (or any other consideration) paid in connection with the Transfer exceeds the Rent otherwise payable by Tenant under this Lease.

15.2    Remedies. Upon the occurrence and during the continuance of any Event of Default, Landlord may at any time and from time to time, and without preventing Landlord from exercising any other right or remedy, exercise any one or more of the following remedies:

15.2.1    Termination of Tenant’s Possession/Re-entry and Reletting Right. Terminate Tenant’s right to possess the Premises by any lawful means with or without terminating this Lease, in which event Tenant shall immediately surrender possession of the Premises to Landlord. In such event, this Lease shall continue in full force and effect (except for Tenant’s right to possess the Premises) and Tenant shall continue to be obligated for and shall pay all Rent as and when due under this Lease. Unless Landlord specifically states that it is terminating this Lease, Landlord’s termination of Tenant’s right to possess the Premises is not to be construed as an election by Landlord to terminate this Lease or Tenant’s obligations and liabilities under this Lease. If Landlord terminates Tenant’s right to possess the Premises, Landlord shall not be obligated to, but may re-enter the Premises and remove all persons and property from the Premises. Landlord may store any property Landlord removes from the Premises in a public warehouse or elsewhere at the cost and for the account of Tenant. Subject to Section 15.3, upon such re-entry, Landlord may but shall not be obligated to relet all or any part of the Premises to a third party or parties for Tenant’s account.

15.2.2    Termination of Lease. Terminate this Lease effective on the date Landlord specifies in Landlord’s notice to Tenant. Upon termination, Tenant shall immediately surrender possession of the Premises to Landlord in accordance with the terms of this Lease. If Landlord terminates this Lease, Landlord may recover from Tenant and Tenant shall pay to Landlord on demand all damages Landlord incurs by reason of Tenant’s default, including, without limitation: (a) all Rent due and payable under this Lease as of the effective date of the termination; and (b) any amount necessary to compensate Landlord for any detriment proximately caused Landlord by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course would likely result from Tenant’s failure to perform, including, but not limited to, any Re-entry Costs, and taking into account Landlord’s obligation to mitigate damages.

15.2.3    Other Remedies. Exercise any other right or remedy available to Landlord under this Lease, or otherwise at law or in equity. Without limitation, Landlord may, at its option, make any payment or perform any covenant for the account of Tenant and, if Landlord makes any expenditure or incurs any obligation for the payment of money, the same shall be due and payable by Tenant upon demand, together with interest thereon at the Default Rate from the date paid by Landlord until repaid.

15.3    Mitigation of Damages. In the event of the occurrence of an Event of Default by Tenant hereunder, Landlord shall exercise commercially reasonable efforts to mitigate Landlord’s damages arising from such Event of Default.

15.4    Costs. Tenant shall reimburse and compensate Landlord on demand and as Additional Rent for any actual loss Landlord incurs resulting from Landlord’s exercise of any of its remedies under Section 15.2. Such loss shall include all reasonable legal fees, costs and expenses Landlord incurs negotiating, settling or enforcing any of Landlord’s rights or remedies or otherwise protecting Landlord’s interests under this Lease. Tenant shall also, to the fullest extent allowable under the Laws, indemnify, defend (with counsel reasonably acceptable to Landlord) and hold harmless the Landlord Parties from and

against all Claims Landlord or any of the other Landlord Parties incurs if Landlord or any of the other Landlord Parties becomes or is made a party to any claim or action: (a) instituted by or against any Person holding any interest in the Premises by, under or through Tenant, except to the extent resulting solely from an act or omission of Landlord or any of Landlord’s Agents; (b) for foreclosure of any lien for labor or material furnished to or for Tenant or such other Person; or (c) otherwise arising out of or resulting from any negligence or willful misconduct of Tenant or such other Person.

15.5    Landlord’s Default. If Landlord defaults in the performance of any of its obligations under this Lease, Tenant shall notify Landlord of the default and Landlord shall have thirty (30) days after receiving such notice to cure the default. If Landlord is not reasonably able to cure the default within a thirty (30) day period, Landlord shall have an additional reasonable period of time to cure the default as long as Landlord commences the cure within the 30-day period and thereafter diligently pursues the cure to completion. In no event shall Landlord be liable to Tenant or any other Person for consequential, special, indirect or punitive damages, including, without limitation, lost profits in connection with this Lease. In the event of a default by Landlord which is not cured after notice and within the applicable cure period Tenant shall be entitled to exercise all remedies at law and in equity, subject to the terms and conditions of this Lease.

15.6    No Waiver. No failure by either party to insist upon the performance of any provision of this Lease or to exercise any right or remedy upon a breach or default thereof, and no acceptance by Landlord of full or partial Rent during the continuance of any such breach or default, shall constitute a waiver of any such breach or default. None of the terms of this Lease to be kept, observed or performed by Landlord or Tenant, and no breach or default thereof, may be waived, altered or modified except by a written instrument executed by Landlord and Tenant. One or more waivers by either party shall not be construed as a waiver of a subsequent breach or default of the same provision. No statement on a payment check from Landlord or Tenant or in a letter accompanying a payment check shall be binding on the other party and the payee party may, with or without notice to the payor party, negotiate such check without being bound to the conditions of any such statement. If Landlord or Tenant pays any amount other than the actual amount due the other party, receipt or collection of such partial payment does not constitute an accord and satisfaction. The payee party may retain any such partial payment, whether restrictively endorsed or otherwise, without prejudice to the other party’s right to collect the balance properly due. If all or any portion of any payment is dishonored for any reason, payment shall not be deemed made until the entire amount due is actually collected by the party entitled thereto. The foregoing provisions apply in kind to the receipt or collection of any amount by a lock box agent or other Person on Landlord’s behalf.

15.7    Self-Help Rights. In addition to the rights set forth in Section 9.3, if Landlord or Tenant fails to timely pay or perform any of its respective obligations under this Lease, which failure is not cured within all applicable notice, grace and cure periods, then the other party shall have the right but not the obligation to advance any such payment and/or perform any such obligation on the defaulting party’s behalf, in which event the amount of any such advance and/or the out-of-pocket cost of any such performance shall (a) bear interest at the Default Rate until paid in full, and (b) together with any accrued interest, be deemed Additional Rent payable by the defaulting party hereunder within fifteen (15) Business Days after delivery by the curing party of an invoice for such amount.

15.8    Dispute Resolution. Disputes arising under, or in connection with, this Lease (excluding an action for forcible detainer which shall be litigated in a court of competent jurisdiction, or any other action required under applicable Laws to be litigated in a court of competent jurisdiction) will be finally settled under the Rules of Arbitration of the International Chamber of Commerce by one arbitrator appointed in accordance with the Rules.  The language of the arbitration will be English. The place of the arbitration will be San Francisco, California.  Judgment upon any award(s) rendered by the arbitrator may be entered in any court having jurisdiction thereof. Notwithstanding the foregoing, either party may seek equitable relief in order to protect its rights, and to cause the other party to perform its obligations, hereunder at any time and in any court having jurisdiction over the parties hereto and/or the subject matter hereof. The parties hereby waive any bond requirements for obtaining equitable relief.

15.9    Bankruptcy.

15.9.1    Timely Performance. Tenant acknowledges that in entering into this Lease, Landlord is relying upon the financial condition and operating experience of Tenant, Tenant’s agreement to timely perform its obligations under this Lease, and all defaults under this Lease being cured promptly. Accordingly, Tenant agrees that if, after the Effective Date hereof, an Insolvency occurs: (a) all obligations that accrue or become due under this Lease (including the obligation to pay Rent), from and after the date that an Insolvency shall be timely performed exactly as provided in this Lease; (b) Rent obligations under this Lease that accrue or become due from and after the date of an Insolvency that are not paid as required by this Lease shall, in the amount of such Rents, constitute administrative expense claims allowable under the Bankruptcy Code with priority of payment at least equal to that of any other actual and necessary expenses incurred after the commencement of the Insolvency; (c) any extension of the time period within which Tenant may assume or reject this Lease without an obligation to cause all obligations accruing or coming due under this Lease from and after the date that an action is commenced to be performed as and when required under this Lease shall be harmful and prejudicial to Landlord; (d) any time period designated as the period within which Tenant must cure all defaults and compensate Landlord for all pecuniary losses which extends beyond the date of assumption of this Lease shall be harmful and prejudicial to Landlord; (e) any assignment of this Lease must result in all terms and conditions of this Lease being assumed by the assignee without alteration or amendment, and any assignment which results in an amendment or alteration of the terms and conditions of this Lease without the express written consent of Landlord shall be harmful and prejudicial to Landlord; (f) any proposed assignment of this Lease to an assignee: (i) that does not possess financial condition adequate to operate in the Premises or operating experience characteristics comparable to Tenant as of the Effective Date, shall be harmful and prejudicial to Landlord; and (ii) the rejection (or deemed rejection) of this Lease for any reason shall constitute cause for immediate relief from the automatic stay provisions of the Bankruptcy Code, and Tenant stipulates that such automatic stay shall be lifted immediately and possession of the Premises will be delivered to Landlord immediately without the necessity of any further action by Landlord.

15.9.2    No Waiver. No provision of this Lease shall be deemed a waiver of Landlord’s rights or remedies under the Bankruptcy Code or applicable law to oppose any assumption and/or assignment of this Lease, to require timely performance of Tenant’s obligations under this Lease, or to regain possession of the Premises as a result of the failure of Tenant to comply with the terms and conditions of this Lease or the Bankruptcy Code.

16.1    Subordination; Non-Disturbance. Upon written request of Landlord, or any first mortgagee, lien of indenture holder or first deed of trust beneficiary of Landlord (“Requesting Entity”), Tenant shall, within fifteen (15) Business Days after Landlord’s reasonable request, in writing, subordinate its rights under this Lease to the lien of any mortgage, lien of indenture or first deed of trust, or to the interest of any lease in which Landlord is lessee, and to all advances made or later to be made thereunder. However, as a condition to Tenant’s obligation to sign any subordination agreement, Tenant shall have the right to obtain from the Requesting Entity, a written subordination, non-disturbance and attornment agreement in a form reasonably acceptable to Tenant providing that, such Requesting Entity shall: (a) recognize Tenant’s rights

under this Lease for the full Term and agrees not to disturb Tenant’s quiet possession of the Premises as long as there is no Event of Default by Tenant, and (b) upon succeeding to Landlord’s interest in the Premises, become bound to Tenant as Landlord under this Lease. The holder of any security interest may, upon written notice to Tenant, elect to have this Lease prior to its security interest regardless of the time of the granting or recording of such security interest. In any foreclosure sale or transfer in lieu of foreclosure, Tenant shall attorn to the purchaser, transferee or lessor as the case may be, and recognize that party as Landlord under this Lease, provided such party acquires and accepts the Premises subject to all of Tenant’s rights under this Lease.

16.2    Estoppel Certificates. Upon written request of either Landlord or Tenant, the other party shall execute, acknowledge and deliver to the requesting party a written statement (“Estoppel Certificate”) in form reasonably satisfactory to the requesting party certifying: (a) that this Lease is unmodified and in full force and effect (or, if there have been any modifications, that the Lease is in full force and effect, as modified, and stating the modifications); (b) that this Lease has not been canceled or terminated; (c) the last date of payment of Rent and the time period covered by such payment; (d) whether there are then existing any breaches or defaults by the requesting party under this Lease known to the certifying party, and, if so, specifying the same; (e) specifying to the certifying party’s actual knowledge any existing claims or defenses in favor of the requesting party against the enforcement of this Lease (or of any guaranties); and (f) such other factual statements as the requesting party, any lender, prospective lender, investor or purchaser may reasonably request. The certifying party will deliver the statement to the requesting party within fifteen (15) Business Days after the requesting party’s reasonable request. The requesting party may give any such statement provided by the certifying party to any lender, prospective lender, investor or purchaser of all or any part of the Premises and any such party may conclusively rely upon such statement as true and correct.

16.3    Failure to Deliver. Tenant shall deliver any subordination instrument required pursuant to Section 16.1 or any Estoppel Certificate to Landlord within fifteen (15) Business Days following Landlord's initial written request. If Tenant fails to do so, and such failure continues unremedied for an additional five (5) Business Days following a Reminder Notice from Landlord, Landlord and any lender, prospective lender, investor or purchaser may conclusively presume that, except as otherwise represented by Landlord: (a) the terms and provisions of this Lease have not been changed; (b) this Lease has not been canceled or terminated; (c) not more than one month’s Rent has been paid in advance; and (d) Landlord is not in default in the performance of any of its obligations under this Lease.

17.1    Surrender of Premises. On or prior to the Expiration Date, unless otherwise agreed in writing by Landlord, Tenant shall either remove all Mesa Equipment and all other property owned by the GTAT Parties from the Premises or move only the ASF Furnaces to the Storage Space, whereupon the obligations of Tenant under this Lease with respect to the condition of the Premises shall be limited to leaving the Premises, other than the Storage Space (which Tenant may continue to occupy pursuant to the Warehouse Lease), in broom clean condition. Tenant shall not have any obligation to remove any Alterations at the expiration or earlier termination of the Term. Tenant will promptly repair any damage to the Premises caused by its or a member of the Tenant Group’s removal of the Tenant’s Property. All property of Tenant or a member of the Tenant Group not removed on or before the last day of the Term (“Remaining Property”) shall be deemed abandoned. Landlord may sell all Remaining Property in a manner consistent with Article 9 of the Uniform Commercial Code; provided that, (i) no further order of the Court (as defined in the Settlement Agreement) shall be required, (ii) thirty (30) days’ notice of any such sale shall be deemed to be commercially reasonable notice, and (iii) Landlord may provide notice of its intent to sell the Remaining Property prior to the end of the Term. Any proceeds received by Landlord from the sale of Remaining Property will be applied in the following order of priority: (A) first, to reimburse Landlord for its costs incurred in connection with the removal and disposition of such Remaining Property; (B) second, to Apple Inc. to satisfy any unpaid portion

of the Apple Claim (as defined in the Settlement Agreement); and (C) third, to the Tenant. Tenant will indemnify and hold Landlord harmless from any claims, loss, injury, liability, or damages (including reasonable attorneys’ fees) incurred by any Landlord Party as a result of persons or firms entering the Premises on Tenant’s behalf to remove Tenant’s Property following expiration or earlier termination of this Lease, including the ASF Furnaces.

18.2    Successors.

The term "Landlord," as used herein, shall mean only the owner of the Premises or of a lease of the Premises, at the time in question, so that in the event of any transfer or transfers of title to the Premises, or of Landlord's interest in a lease of the Premises, the transferor shall be relieved and freed of all obligations of Landlord under this Lease accruing after such transfer, and it shall be deemed, without further agreement, that such transferee has assumed and agreed to perform and observe all obligations of Landlord under this Lease during the period it is the holder of Landlord's interest under this Lease.

18.3    Captions. The section headings in this Lease are for convenience only and are not to be considered in construing or interpreting the Lease.

The word “party” means a party to the Lease and the phrase “third party” means any person, partnership, corporation or other entity not a party to the Lease. The words “will” and “shall” are used in a mandatory, not a permissive, sense, and the word “including” is intended to be exemplary, not exhaustive, and will be deemed followed by “without limitation.” Any requirement to obtain a party’s consent is a requirement to obtain such consent in each instance.

18.4    Relationship of Parties. Nothing in this Lease creates a joint venture, partnership, franchise, employment or agency relationship or fiduciary duty of any kind. Neither party will have the power, and will not hold itself out as having the power, to act for or in the name of or to bind the other party. Except as expressly provided, this Lease is not for the benefit of any third parties.

18.5    Entire Agreement; Amendment. The parties agree that this Lease (including the exhibits, addenda and schedules attached to the Lease) and the Amended Settlement Agreement, constitute the complete and exclusive agreement between them with respect to the subject matter of this Lease, superseding all contemporaneous and prior agreements (written and oral) and all other communications between them relating to the subject matter of this Lease. Except as expressly provided herein, the Lease may not be amended or modified except by a written amendment specifically referencing the Lease, signed by authorized signatories of both parties. The parties expressly acknowledge that they have received and are in possession of a copy of any referenced item not physically attached to the Lease and any such item will be treated as if attached.

18.6    Severability. If a court of competent jurisdiction finds any provision of this Lease unlawful or unenforceable, that provision will be enforced to the maximum extent permissible so as to effect the intent of the parties, and the remainder of the Lease will continue in full force and effect

18.7    Landlord’s Limited Liability. Tenant shall look solely to Landlord’s interest in the Premises and the rents and profits therefrom for recovering any judgment or collecting any obligation from Landlord or any other Landlord Party with respect to any breach of this Lease.

18.8    Survival. All obligations under this Lease (together with interest on payment obligations at the Default Rate) accruing prior to expiration or other termination of this Lease survive the expiration or other termination of this Lease. Further, all of Landlord’s and Tenant’s releases and indemnification, defense and hold harmless obligations under this Lease survive the expiration or other termination of this Lease for the duration of the application statute of limitations, unless otherwise expressly provided in this Lease.

18.9    Attorneys’ Fees. If either Landlord or Tenant commences any litigation or judicial action to determine or enforce any of the provisions of this Lease, the prevailing party in any such litigation or judicial action is entitled to recover all of its costs and expenses (including, but not limited to, reasonable attorneys’ fees, costs and expenditures) from the non-prevailing party.

18.10    Brokers. Landlord and Tenant each represents and warrants to the other that it has not had any dealings with any realtors, brokers, finders or agents in connection with this Lease and each releases and agrees, to the fullest extent allowable under the Laws, to indemnify, defend and hold the other harmless from and against any Claims based on the failure or alleged failure to pay any realtors, brokers, finders or and from any cost, expense or liability for any compensation, commission or changes claimed by any realtors, brokers, finders or agents claiming by, through or on behalf of it with respect to this Lease or the negotiation of this Lease.

Landlord and each individual signing this Lease on behalf of Landlord represents and warrants that they are duly authorized to sign on behalf of and to bind Landlord and that this Lease is a duly authorized, binding and enforceable obligation of Landlord. Landlord has been duly organized or formed, is validly existing and in good standing under the laws of its state of formation and is qualified as a foreign limited liability company to do business in the State. The authorization, execution, delivery, and performance of this Lease will not result in any breach of or default under any document, instrument or agreement to which Landlord is a party or by which Landlord is bound.

18.14    Tenant’s Authority. Tenant and each individual signing this Lease on behalf of Tenant represents and warrants that they are duly authorized to sign on behalf of and to bind Tenant and that this Lease is a duly authorized, binding and enforceable obligation of Tenant.

18.15    No Merger. There shall be no merger of this Lease nor of the leasehold estate created by this Lease with the fee estate in or ownership of the Premises by reason of the fact that the same Person may acquire or hold or own, directly or indirectly: (a) this Lease or the leasehold estate created by this Lease or any interest in this Lease or in such leasehold estate; and (b) the fee estate or ownership of the Premises or any interest in such fee estate or ownership. No such merger shall occur unless and until all persons, corporations, firms and other entities having any interest in: (i) this Lease or the leasehold estate created by this Lease; and (ii) the fee estate in or ownership of the Premises or any part thereof sought to be merged shall join in a written instrument effecting such merger and shall duly record the same.

18.16    Provisions are Covenants and Conditions. All provisions of this Lease, whether covenants or conditions, are deemed both covenants and conditions.

18.17    Force Majeure. Neither party will be liable for any failure to perform under this Lease (excluding, however, the payment of money) caused by circumstances beyond its reasonable control, including, but not limited to, acts of God, earthquakes, hurricanes, floods, tornados, fires, acts of war, hostilities, invasions, terrorism, civil disorder, riots, labor actions (other than actions by personnel or contractors of the party invoking force majeure), major upheavals, government action, government restrictions, blockade, embargo, utility disruptions, including power and water, or accident (“Force Majeure Event”), provided: (a) it promptly notifies the other party and uses reasonable efforts to correct its failure to perform; and (b) it has taken such commercially reasonable efforts to protect against and mitigate the impact of the Force Majeure Event if such Force Majeure Event was reasonably foreseeable or was of a kind for which such precautionary measures are customarily taken in the applicable industry. For the avoidance of doubt, any circumstance caused primarily by one or more Mesa Equipment or any other of Tenant’s Property, will not constitute a Force Majeure Event, and the provisions of this Section 18.17 will not apply.

18.18    Non-Subordinated Lease. This is a nonsubordinated lease. Landlord shall not be obligated to subordinate its rights in the Premises to any loan or money encumbrance that Tenant shall place against Tenant’s leasehold estate in the Premises.

18.19    Quiet Enjoyment. Landlord covenants and agrees that Tenant shall have the right to peaceful and quiet enjoyment and occupancy of the Premises during the Term, subject to the terms and conditions of this Lease free from molestation or hindrance by Landlord or any Person claiming by, through or under Landlord, if Tenant pays all Rent as and when due and keeps, observes and fully performs all other covenants, obligations and agreements of Tenant under this Lease within all applicable notice, grace and cure periods.

18.20    Counterparts. This Lease may be executed in one or more counterparts, each of which shall be deemed an original but all of which will constitute one and the same instrument. Signature and acknowledgment pages may be detached from individual counterparts and attached to a single or multiple original(s) in order to form a single or multiple original(s) of this document.

18.21    Nondisclosure of Lease Terms. Subject to the Amended Settlement Agreement, the terms and conditions of this Lease constitute proprietary information of Landlord and Tenant. Accordingly, Landlord and Tenant shall not, without mutual consent (which consent either party may grant or withhold in its sole and absolute discretion), directly or indirectly disclose the terms and conditions of this Lease to any other Person other than Landlord’s and Tenant’s employees, professional consultants and agents who have a legitimate need to know such information (and who shall also keep the same in confidence) or to Landlord’s prospective purchasers or lenders or Tenant’s prospective assignees or subtenants, who in each case shall have agreed in writing to keep the same in confidence, or pursuant to a court or governmental subpoena or order, or to the extent otherwise required by law, provided that if either party receives such a subpoena or order or is required by law to disclose the other party’s proprietary information, it shall give timely notice to the other, and takes reasonable steps to obtain protective treatment of the proprietary information. In the event either party is expressly permitted to disclose any proprietary information of the other party (or such other party’s applicable affiliate) pursuant to the terms of the Amended Settlement Agreement, then, provided such disclosing party complies (or causes its applicable affiliate to comply) fully with such relevant terms of the Amended Settlement Agreement, such disclosure shall not be deemed a violation under this Section 18.21.

18.22    Construction of the Terms. The terms and provisions of this Lease represent the results of negotiations between Landlord and Tenant, each of which are sophisticated parties and each of which has been represented or been given the opportunity to be represented by counsel of its own choosing, and neither of which has acted under any duress or compulsion, whether legal, economic or otherwise. Consequently, the terms and provisions of this Lease shall be interpreted and construed in accordance with

their usual and customary meanings, and Landlord and Tenant each waive the application of any rule of law that ambiguous or conflicting terms or provisions contained in this Lease are to be interpreted or construed against the party who prepared the executed Lease or any earlier draft of the same.
