NOW THEREFORE, in consideration of the mutual representations, warranties, covenants and agreements set forth herein and of good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and notwithstanding any provision in the Apple Contracts or any other prior agreement, arrangement or understanding between or among the GTAT Parties or the Apple Parties to the contrary, the Parties hereby agree as follows:

1.Mesa Equipment and Mesa Facility.

(a)    Mesa Equipment. Pursuant to the Apple Contracts, GTAT Corp. or SPE purchased the components of and installed 2,036 ASF Furnaces (the “Mesa ASF Furnaces”) for the manufacture of sapphire materials at the facility (the “Mesa Facility”) leased by GTAT Corp. under the Facility Lease Agreement between Platypus and GTAT Corp. dated as of October 31, 2013 (the “Mesa Lease”). Certain of the GTAT Parties also purchased, for use at the Mesa Facility, certain fabrication and other equipment (the “Mesa Fabrication Equipment”) required for the fabrication of sapphire boules into Goods, the mezzanine and other equipment related to the Mesa ASF Furnaces, inspection and testing equipment, ASF Furnaces not included in the definition of Mesa ASF Furnaces, information technology and ancillary equipment purchased by such GTAT Parties pursuant to the SOW (“Other Mesa Equipment” and, collectively with the Mesa ASF Furnaces and Mesa Fabrication Equipment, the “Mesa Equipment”).

(b)    Ownership of Mesa Equipment, Inventory and Related Assets. The Approval Order (as hereinafter defined), shall find and declare: (i) SPE is the owner of the Mesa ASF

Furnaces, (ii) GTAT Corp. is the owner of the Mesa Equipment (other than the Mesa ASF Furnaces) and all spare parts, accessions, tooling, warranties, software, and know-how related to the Mesa Equipment (other than the Mesa ASF Furnaces), and all inventory, raw materials, consumables, work in process and finished Goods located at the Mesa Facility (the “Mesa Inventory”) and (iii) GTAT Corp. is the owner of all furnaces and equipment located at GTAT Corp.’s Salem, Massachusetts facility (the “Salem Facility”) and all spare parts, accessions, tooling, warranties, software and know-how related to such equipment (the “Salem Equipment”) and all inventory raw materials, consumables, work in process and finished Goods located at the Salem Facility (the “Salem Inventory”), in each case, free and clear of any claims, liens or interests of the Apple Parties (other than the Apple Security Interest (as defined below, but only to the extent provided below )).

(c)    Mesa Facility. The Parties agree that Platypus is the owner of the Premises and Improvements, the Landlord Work, the Roof Solar Array, the Solar Basis, the Fuel Cells (if any) and the Electrical Substation (which shall be owned by a utility provider) and the portion of the Land on which the Electrical Substation is located (each as defined in the Mesa Lease), as well as all other real or personal property located at the Premises (other than the Mesa Equipment, the Mesa Inventory and certain other equipment owned by the Apple Parties’ third party contractors), free and clear of any interest or claim of the GTAT Parties.

2.    Apple Claim and Security Interest in Mesa ASF Furnaces.

(a)    The Parties agree that Apple shall have an allowed claim of $439,000,000 against SPE secured by the Mesa ASF Furnaces, subject to reduction as provided below (the “Apple Claim”). Subject to Section 2(b) hereof, the Apple Claim shall be a non-recourse claim recoverable solely from the Mesa ASF Furnaces. The Approval Order (as defined below) shall provide that Apple holds a fully-perfected security interest in the Mesa ASF Furnaces to secure payment of the Apple Claim (the “Apple Security Interest”), and except as otherwise provided herein, Apple’s sole rights and remedies under the Apple Claim or the Apple Security Interest shall be (i) to receive the Apple Repayment Amount (as defined below) and (ii) (A) on or after the date that is forty-eight (48) months after the date of this Settlement Agreement (the “Maturity Date”), to the extent the Apple Claim has not been repaid in full on or after the Maturity Date,

foreclose on any remaining Mesa ASF Furnaces or (B) prior to the Maturity Date, to the extent that any Apple Repayment Amount payable by the GTAT Parties has not been paid at any time that the GTAT Parties have no obligations under any Priming Financing (as defined below), to foreclose on such number of remaining Mesa ASF Furnaces as is necessary to recover such Apple Repayment Amount. The Approval Order shall also provide that Apple shall be entitled to exercise the foreclosure rights set forth in clause (ii) of this Section 2(a) without the necessity of obtaining any further order from the Bankruptcy Court. Each of the GTAT Parties hereby agrees that it will not oppose the foreclosure set forth in clause (ii) of this Section 2(a). Apple shall have an administrative expense claim against the bankruptcy estate of any GTAT Party that fails to pay amounts that it owes under this Settlement Agreement while such GTAT Party is a debtor under the Bankruptcy Code. Nothing in this Settlement Agreement shall restrict any right of Apple to sue any GTAT Party that is no longer subject to a case under the Bankruptcy Code for breach of its obligations under this Settlement Agreement and to obtain and enforce any judgment lien that Apple might obtain against any such GTAT Party’s assets. Pursuant to the Approval Order (as defined below), the Apple Security Interest shall be determined to be a perfected security interest, and such Approval Order shall also provide that the Apple Claim and Apple Security Interest shall be junior only to the claims under or liens securing Priming Financing. The Approval Order shall also permit Apple to file financing statements to provide additional notice of the Apple Security Interest without the necessity of obtaining further relief from the Bankruptcy Court.

(b)    The Apple Claim shall be paid as follows, without interest, fees or other charges, costs or fixed amortization (other than for the Apple Repayment Amount). Prior to an event of default under any Priming Financing and the consequent acceleration and taking of actions to seize or foreclose on any GTAT Parties’ property by or on behalf of the lenders under the Priming Financing, Apple will receive for each ASF Furnace a GTAT Party sells an amount in cash as provided in the schedule set forth in Exhibit B hereto (the “Apple Repayment Amount”), it being understood that Apple will receive the Apple Repayment Amount regardless of whether the ASF Furnace sold is a Mesa ASF Furnace. GTAT Corp. or SPE shall, or GTAT Corp. shall cause an affiliate (other than GT HK) to, pay to Apple the Apple Repayment Amount within three (3) business days following receipt of payment in respect of an ASF Furnace (including payments designated as warranty or maintenance or other after-sale services); provided, that, if

the purchase price is less than the Apple Repayment Amount, GTAT Corp. or SPE shall, or GTAT Corp. shall cause an affiliate (other than GT HK) to, pay to Apple the amount of the shortfall not later than three (3) business days following the earlier of receipt of the final payment from the purchaser or the date such final payment was due to be paid by the purchaser. If the market price of furnaces that are similar to the ASF Furnaces drops below the Apple Repayment Amount set forth in Exhibit B hereto, Apple and GTAT Corp. shall re-negotiate in good faith the amount of the Apple Repayment Amount for the quantity of ASF Furnaces that remains unsold at such time. For the avoidance of doubt, the Apple Repayment Amount shall be paid from the first dollar of purchase price allocable to the sale of such ASF Furnace (net of customary installation, logistics or shipping charges) (and the GTAT Parties shall not retain any proceeds from a sale (other than any such customary charges) until the Apple Repayment Amount is paid in full to Apple), and any Apple Repayment Amount received by Apple shall result in a dollar-for-dollar reduction in the amount of the Apple Claim. The GTAT Parties shall not lease ASF Furnaces, and shall not dispose of ASF Furnaces other than pursuant to arm’s-length sales to third parties for cash. Without limiting the obligations of GTAT Corp. or SPE hereunder, GT HK shall have no obligation to pay any part of the Apple Repayment Amount, including in the event of sale of any ASF Furnace by GT HK.

(c)    After an event of default under any Priming Financing and the consequent acceleration and taking of actions to seize or foreclose on any GTAT Parties’ property by or on behalf of the lenders under the Priming Financing, Apple shall not receive any proceeds from the sale of ASF Furnaces until and unless all obligations under the Priming Financing have been paid in full and in cash. The right of Apple to receive the Apple Repayment Amount shall be granted to Apple as adequate protection for the priming of its security interest pursuant to Section 3 hereof, which priming by the Priming Financing will allow for the funding of the operations of all GTAT Parties. This shall be the only form of adequate protection granted to Apple, Apple’s liens on such assets shall be junior to the liens securing such Priming Financing. For each ASF Furnace that is not a Mesa ASF Furnace for which Apple receives the Apple Repayment Amount, Apple’s security interest in a Mesa ASF Furnace shall be released.

(d)    Each GTAT Party shall use its respective commercially reasonable best efforts to sell the ASF Furnaces for cash. For the avoidance of doubt, “commercially reasonable best

efforts” shall include, without limitation, efforts consistent with past practices of the GTAT Parties.

(e)    For the period ending on the earlier of (i) repayment of the Apple Claim in full and (ii) the Maturity Date, GTAT Corp. shall, and shall cause the GTAT Parties to, (A) provide quarterly reports with respect to the sale of the ASF Furnaces during such period, (B) participate in a quarterly conference call with representatives of Apple to discuss sales activity and estimated future sales, and (C) grant the Apple Parties and their authorized personnel access to the books and records of the GTAT Parties related to the sale of ASF Furnaces, in each case, as Apple may reasonably request.

(f)    For so long as the Apple Claim has not been repaid in full, Apple shall have the right, but not the obligation, to purchase one or more ASF Furnaces at a price to be agreed between Apple and GTAT Corp. If the sales price is equal to or less than the Apple Repayment Amount, the purchase price shall be paid by applying the sales price against the Apple Claim. If the sales price is greater than the Apple Repayment Amount, a portion of the sales price equal to the Apple Repayment Amount shall be applied against the Apple Claim and Apple shall pay to GTAT Corp. in cash any amount in excess of the Apple Repayment Amount.

(g)    Apple shall have the right to bid at any public or private sale of the ASF Furnaces in connection with any exercise of remedies by the lenders under the Priming Financing, but may only credit bid if any Priming Financing is paid in full in cash or the lenders under the Priming Financing consent).

(h)    Notwithstanding anything to the contrary contained in this Settlement Agreement, insurance proceeds received in respect of damage to the Mesa ASF Furnaces shall be treated as proceeds of sale as if the applicable Mesa ASF Furnace had been sold by a GTAT Party.

3.    GTAT Corp. DIP Facility. GTAT Corp. may obtain a debtor-in-possession financing agreement subject to approval of the Bankruptcy Court (the “DIP Facility”). Apple consents to the priming of its security interest in the Mesa ASF Furnaces in an amount equal to $150,000,000 principal amount plus interest, fees and costs in connection with (i) the DIP Facility or any subsequent post-petition financing in the Chapter 11 Cases that refinances the

DIP Facility, (ii) any exit financing (or any refinancing thereof) in the Chapter 11 Cases upon consummation of Chapter 11 plans for the GTAT Parties that refinances the DIP Facility, and (iii) any financing obtained by any of the GTAT Parties at any time prior to the Maturity Date (any of items (i), (ii) and (iii), a “Priming Financing”). For the avoidance of doubt, Apple’s agreement to be subordinated to up to $150,000,000 of Priming Financing shall apply to any refinancing, whether or not the amount being refinanced is less than $150,000,000. The agreement of Apple to be subordinated as provided herein shall be conditioned on the effectiveness of this Settlement Agreement at the time such DIP Facility is entered into and the GTAT Parties not being in default under this Settlement Agreement at the time the Priming Financing is entered into and on the continued agreement of lenders under the Priming Financing to permit, prior to a continuing event of default and acceleration and acceleration and exercise of remedies by or on behalf of the lenders under the Priming Financing, the payment of proceeds of transfer to Apple as provided in Section 2.

4.    GTAT Corp. Intellectual Property.

(a)    Termination of Agreements and Reconveyance of IP. The Apple Contracts shall be deemed terminated as of the Effective Date, other than the Mesa Lease (which shall be amended as described in Section 8 hereof and Exhibit C of this Settlement Agreement) and the Confidentiality Agreement between Apple and GTAT Corp. dated August 24, 2012 and the Confidentiality Agreement dated October 31, 2013, between Apple Inc. and GT Advanced Equipment Holding LLC (collectively, the “Confidentiality Agreements”). Apple shall have no rights to GTAT Parties’ intellectual property pursuant to Bankruptcy Code § 365(n) or otherwise, except as provided herein. Without limiting the foregoing, but subject to the remainder of this Section 4, Apple and GTAT Corp. agree that (i) Apple shall have no rights to sapphire growth technology created by GTAT Parties, and it hereby releases any and all rights it holds therein except as provided below; (ii) all rights that Apple may have acquired with respect to Project Work Product (as defined in the MDSA) shall immediately and automatically revert to GTAT Corp. on the Effective Date, other than that relating to annealing (including, but not limited to, that created under the Statement of Work dated March 31, 2014) and Intellectual Property Rights

(as defined in the MDSA) therein or thereto and, upon such reversion, Apple releases any claim it may have thereto, including pursuant to Section 3 of attachment 2 to the MDSA and Section 10 of the SOW or any other provisions of the Apple Contracts other than Sections 4.4 and 4.5 of attachment 2 to the MDSA; (iii) as between Apple and the GTAT Parties, Apple shall be the owner of all Intellectual Property Rights relating to annealing, and the GTAT Parties hereby irrevocably assign to Apple such Intellectual Property Rights throughout the world; and (iv) the GTAT Parties shall have no restrictions whatsoever on licensing of their intellectual property or selling equipment (including ASF Furnaces) or sapphire products incorporating or embodying such intellectual property. Apple agrees that the sale or use of ASF Furnaces and the sale or use of the Mesa Inventory or the Salem Inventory and sale or use of the Mesa Equipment does not infringe on any of Apple’s intellectual property. Notwithstanding anything herein to the contrary, when and if Apple acquires ASF Furnaces from a GTAT Party, such GTAT Party shall grant Apple or its affiliates, partners, suppliers or manufacturers, as the case may be, a perpetual, non-exclusive use license with respect thereto, provided that, such use is limited to products sold by Apple under a brand owned by Apple or its affiliates.

(b)    Residuals. Notwithstanding the confidentiality obligations contained in the Confidentiality Agreements set forth in Section 4(a) above, Apple and its affiliates, on the one hand, or the GTAT Parties, on the other hand, may use in their respective business any Residual Information of the other party. Apple and GTAT hereby covenant not to initiate any claim, legal action or proceeding alleging misappropriation of any intellectual property right based upon the use of Residual Information as permitted hereunder. “Residual Information” means information of a general nature, such as general knowledge, ideas, professional skills, know-how, work experience and techniques that is retained in the unaided memories of the receiving party’s employees, customers or users who have had access to the disclosing party’s confidential information. Memory shall be considered unaided (i) if the employee, customer or user has not intentionally or consciously memorized the confidential information for the purpose of retaining and subsequently using or disclosing it; or (ii) the confidential information is not subsequently referenced or used. Notwithstanding the foregoing, this provision does not grant any licenses to the receiving party under any patent, trademarks or copyrights of the disclosing party.

(c)    Collateral. The GTAT Parties hereby grant Apple and its affiliates a perpetual, irrevocable, fully paid, royalty-free, worldwide, non-exclusive license under all Intellectual Property Rights now or hereafter owned, controlled or licensable by the GTAT Parties to use, maintain, repair and enhance the Mesa ASF Furnaces that have been foreclosed upon and to make, have made, use, purchase, sell, offer for sale, license, lease, import, export, and otherwise dispose of or exploit materials and products created in such Mesa ASF Furnaces. The GTAT Parties shall, upon request from Apple, disclose to Apple any tangible embodiments of such Intellectual Property Rights. Apple shall have the right to transfer this license in connection with any sale of such Mesa ASF Furnaces following exercise of Apple’s right of foreclosure.

(d)    Fabrication and Inspection. The GTAT Parties hereby grant Apple, and Apple (on behalf of itself and its affiliates) hereby grants the GTAT Parties a perpetual, irrevocable, royalty-free, fully paid, worldwide, nonexclusive license to use all sapphire fabrication and inspection technology developed by the GTAT Parties, on the one hand, and by Apple, on the other, pursuant to the Apple Contracts as of the date hereof to design, develop, make, have made, use, purchase, sell, offer for sale, license, lease, import, export and otherwise dispose of or exploit any products and services whatsoever (including, for avoidance of doubt, the right to have such products further finished and combine them with other items to create a larger product); provided, however, this Section 4(d) shall not apply to any Fabrication and Processing Technology (as defined in Section 7.1.9 of the SOW).

(f)    For the avoidance of doubt, the Parties agree and acknowledge that GTAT Corp. does not own the rights to the Intego inspection technology, but is the exclusive distributor of equipment based on such technology. Apple may, accordingly, purchase Intego inspection equipment from GTAT Corp. on terms to be mutually agreed.

5.    Mutual Release of Claims. In consideration of the foregoing, effective as of the Effective Date, (i) the Apple Parties do hereby release, remise and forever discharge GTAT Corp. and the GTAT Parties and their current and former officers, directors, agents, attorneys, employees, affiliates, advisors, consultants, attorneys, shareholders and members (collectively, “GTAT Releasees”) of and from all debts, demands, actions, causes of action, suits, accounts, covenants, contracts, agreements, claims, rights, damages, losses or liabilities of any kind or nature whatsoever, both at law or in equity, whether known or unknown which arose at any time prior to the Effective Date, or which hereafter could arise based on any act, fact, transaction, cause, matter or thing which occurred prior to the Effective Date related to the Apple Contracts or the business relationship between Apple and GTAT Corp., and (ii) each of the GTAT Parties does hereby release remise and forever discharge the Apple Parties and their current and former officers, directors, agents, attorneys, employees, affiliates, advisors, consultants, attorneys, shareholders and members (collectively, “Apple Releasees”) of and from all debts, demands, actions, causes of action, suits, accounts, covenants, contracts, agreements, claims, rights, damages, losses or liabilities of any kind or nature whatsoever, both at law or in equity, whether known or unknown which arose at any time prior to the Effective Date, or which hereafter could arise based on any act, fact, transaction, cause, matter or thing which occurred prior to the Effective Date related to the Apple Contracts or the business relationship between Apple and GTAT Corp.

1.    The following defined terms and meanings are added to Exhibit A of the Mesa Lease:

“Mesa Equipment” has the meaning set forth in the Settlement Agreement.

“Mesa Inventory” has the meaning set forth in the Settlement Agreement.

“Settlement Agreement” means the Adequate Protection and Settlement Agreement made and entered as of October [•], 2014, by and among Apple Inc., a California corporation, Landlord, Tenant, and the affiliates of Tenant that are signatories thereto, as amended or restated from time to time.

2.    All references in the Mesa Lease to the “Furnaces” are deleted and replaced with the “Mesa Equipment.”

3.    The Landlord shall have no further obligations to build out the Premises under Section 2 of the Mesa Lease.

4.    The last sentence of Section 1.7 of the Mesa Lease is deleted and replaced with the following: “The term “Expiration Date” means the first of the following dates to occur: (i) the date that is 90 days after the date on which either Landlord or Tenant provides the other with a written notice electing to terminate this Lease, provided that Landlord may not deliver such notice prior to June 15, 2015, and (ii) the Maturity Date.”

5.    Section 4.1 of the Mesa Lease is deleted and replaced with the following: “The Premises may be used solely for the purpose of (a) winding down the business formerly conducted by the Tenant at the Mesa Facility in a manner consistent with the [Wind-Down Plan] and (b) in furtherance thereof, storing, mothballing, decommissioning, selling and shipping, all at the Tenant’s expense, the Mesa ASF Furnaces, Mesa Fabricating Equipment, and the Other Mesa Equipment, and for no other purpose. For the avoidance of doubt, the GTAT Parties will not

conduct operations at the Mesa Facility for the manufacture of sapphire for commercial sale and will not do further loading of the furnaces.”

6.    Notwithstanding the terms of Section 1.1.3, 2.5, 4.2, 7.2, or any other provision of the Mesa Lease, Tenant shall have no obligation to make any repair, replacement or improvement, perform any maintenance or other work, or expend any funds, in connection with any requirement under the Mesa Lease or any matter relating to the Premises that would require Tenant make any expenditure that is, under generally accepted accounting principles consistently applied, of a capital nature. Notwithstanding the forgoing, if the need for any capital expenditure at the Premises is attributable to Tenant’s negligence or its failure to perform ordinary and routine maintenance of the Premises reasonably necessary to keep them in as good order or repair as they were on the final Applicable Phase Delivery Date, reasonable wear and tear and fire and casualty excepted, then Tenant shall make the necessary repair or replacement. On or prior to the Expiration Date the GTAT Parties shall remove all Mesa Equipment and all other property owned by the GTAT Parties from the Mesa Facility, whereupon the obligations of GTAT Corp. under the Mesa Lease with respect to the condition of the Premises shall be limited to leaving the Premises in broom clean condition.

7.    Notwithstanding Section 2.5 or any other provision of the Mesa Lease, Tenant shall have no obligation to pay any assessment imposed in accordance with applicable Laws for public improvements or benefits (including, if applicable, improvement districts and community facilities districts).

(i)    All references in the Mesa Lease to the Apple Contracts, other than the Mesa Lease itself are deleted.

(ii)    The fourth sentence of Section 17.1.

(iii)    The second sentence of Section 14.1.

(iv)    Section 15.1.3, and the last sentence of Section 15.4.

9.    Each of Landlord and Tenant agrees to 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.

10.    Apple need not obtain relief from the automatic stay to provide notice to terminate the Mesa Lease. Prior to the termination or expiration of the Mesa Lease, unless otherwise agreed in writing by Apple, GTAT Corp. shall remove all remaining Mesa ASF Furnaces, Mesa Fabricating Equipment, Other Mesa Equipment and Inventory from the Mesa Facility.

11.    Within fifteen (15) days of the Effective Date, Apple will provide a restated amendment of the Mesa Lease consistent with this Settlement Agreement and the parties will negotiate in good faith to agree on that restatement.
