 (b) Such Grantor will furnish to the Collateral Agent and the Lenders from time to time statements and
schedules further identifying and describing the assets and property of such Grantor and such other reports in connection therewith as the Collateral Agent may reasonably request. In addition, within 30 days after the end of each calendar quarter,
such Grantor will deliver to the Collateral Agent a written supplement substantially in the form of Annex A hereto with respect to any additional Copyrights, Patents and Trademarks registered or applied for with the United States Patent and
Trademark Office or the United States Copyright Office and acquired by such Grantor after the date hereof, all in reasonable detail. 
 (c)
Subject to clause (d) below and Section 3.2(c), each Grantor agrees that at any time and from time to time, at the expense of such Grantor, it will execute any and all further documents, financing statements, agreements and instruments,
and take all such further actions (including the filing and recording of financing statements and other documents, including all applicable documents required under Section 3.2(b)(i)(C)), which may be required under any applicable law, or which
the Collateral Agent or the Required Secured Parties may reasonably request, in order (i) to grant, preserve, protect and perfect the validity and priority of the Security Interests created or intended to be created hereby or (ii) to
enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any 

  

 -11- 

 
Collateral, including the filing of any financing or continuation statements under the Uniform Commercial Code in effect in any jurisdiction with respect to
the Security Interests created hereby and all applicable documents required under Section 3.2(b)(i)(C), all at the expense of such Grantor. 
 (d) Notwithstanding anything in this Section 4.1 to the contrary, (i) with respect to any assets acquired by such Grantor after the date hereof that are required by the Credit Agreement to be subject to the Lien created hereby or
(ii) with respect to any Person that, subsequent to the date hereof, becomes a Domestic Subsidiary that is required by the Credit Agreement to become a party hereto, the relevant Grantor after the acquisition or creation thereof shall promptly
take all actions required by the Credit Agreement or this Section 4.1. 
 (e) The Collateral Agent has a first priority security
interest in the Deposit L/C Loan Collateral Account which security interest is perfected by Control (as defined in Section 9-104 of the UCC). No Pledgor shall grant Control of the Deposit L/C Loan Collateral Account to any person other than the
Collateral Agent and no Pledgor shall grant Control of any other Deposit Account to any other Person, except in connection with a Permitted Lien. 
 4.2. Changes in Locations, Name, etc. Each Grantor will furnish to the Collateral Agent promptly (and in any event within 30 days of such change) a written notice of any change (i) in its legal name, (ii) in its
jurisdiction of organization or location for purposes of the UCC, (iii) in its identity or type of organization or corporate structure or (iv) in its Federal Taxpayer Identification Number or organizational identification number. Each
Grantor agrees promptly to provide the Collateral Agent with certified organizational documents reflecting any of the changes described in the first sentence of this paragraph. Each Grantor also agrees promptly to notify the Collateral Agent if any
material portion of the Collateral is damaged or destroyed. 
 4.3. Notices. Each Grantor will advise the Collateral Agent and the
Lenders promptly, in reasonable detail, of any Lien of which it has knowledge (other than the Security Interests created hereby or Liens permitted under the Credit Agreement) on any of the Collateral which would adversely affect, in any material
respect, the ability of the Collateral Agent to exercise any of its remedies hereunder 
 4.4. Bundled Payments. From and after the
date hereof, no Grantor shall voluntary include Bundled Payment Amounts in a bundled bill. 
 5. Remedial Provisions. 
 5.1. Certain Matters Relating to Accounts. 
 (a) At any time after the occurrence and during the continuance of an Event of Default and after giving reasonable written notice to the Company and any other relevant Grantor, the Administrative Agent shall have the right, but not the
obligation, to instruct the Collateral Agent to (and upon such instruction, the Collateral Agent shall) make test verifications of the Accounts that are Collateral (the “Subject Accounts”) in any manner and through any medium that
such Agent reasonably considers advisable, and each Grantor shall furnish all such assistance and information as such Agent may require in connection with such test verifications. Such Agent shall have the absolute right to share any information it
gains from such inspection or verification with any Secured Party. 
  

 -12- 

 (b) The Collateral Agent hereby authorizes each Grantor to collect such Grantor’s Subject Accounts
and the Collateral Agent may curtail or terminate said authority at any time after the occurrence and during the continuance of an Event of Default. If required in writing by the Collateral Agent at any time after the occurrence and during the
continuance of an Event of Default, any payments of Subject Accounts, when collected by any Grantor, (i) shall be forthwith (and, in any event, within two Business Days) deposited by such Grantor in the exact form received, duly endorsed by
such Grantor to the Collateral Agent if required, in a Collateral Account maintained under the sole dominion and control of and on terms and conditions reasonably satisfactory to the Collateral Agent, subject to withdrawal by the Collateral Agent
for the account of the Secured Parties only as provided in Section 5.5, and (ii) until so turned over, shall be held by such Grantor in trust for the Collateral Agent and the Secured Parties, segregated from other funds of such Grantor.
Each such deposit of Proceeds of Subject Accounts shall be accompanied by a report identifying in reasonable detail the nature and source of the payments included in the deposit. 
 (c) At the Collateral Agent’s written request at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall
deliver to the Collateral Agent all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to the Subject Accounts, including all original orders, invoices and shipping receipts. 
 (d) Upon the occurrence and during the continuance of an Event of Default, a Grantor shall not grant any extension of the time of payment of any of the
Subject Accounts, compromise, compound or settle the same for less than the full amount thereof, release, wholly or partly, any Person liable for the payment thereof, or allow any credit or discount whatsoever thereon if the Collateral Agent shall
have instructed the such Grantor in writing not to grant or make any such extension, credit, discount, compromise or settlement under any circumstances during the continuance of such Event of Default. 
 (e) At the direction of the Collateral Agent, upon the occurrence and during the continuance of an Event of Default, each Grantor shall grant to the
Collateral Agent to the extent assignable, an irrevocable, non-exclusive, fully paid-up, royalty-free, worldwide license to use, assign, license or sublicense any of the Intellectual Property now owned or hereafter acquired by such Grantor. Such
license shall include access to all media in which any of the licensed items may be recorded or stored and to all computer programs used for the compilation of printout thereof. 
 5.2. Communications with Credit Parties; Grantors Remain Liable. 
 (a) The Collateral Agent in its own name or in the name of others may at any time after the occurrence and during the continuance of an Event of Default, after giving reasonable written notice to the relevant Grantor
of its intent to do so, communicate with obligors under the Subject Accounts to verify with them to the Collateral Agent’s satisfaction the existence, amount and terms of any Subject Accounts. The Collateral Agent shall have the absolute right
to share any information it gains from such inspection or verification with any Secured Party. 
 (b) Upon the written request of the
Collateral Agent at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall notify obligors on the Subject Accounts that the Subject Accounts have been assigned to the Collateral Agent for the benefit of
the Secured Parties and that payments in respect thereof shall be made directly to the Collateral Agent. 
  

 -13- 

 (c) Anything herein to the contrary notwithstanding, each Grantor shall remain liable under each of the
Subject Accounts to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto. Neither the Collateral Agent nor any Secured Party shall
have any obligation or liability under any Subject Account (or any agreement giving rise thereto) by reason of or arising out of this Security Agreement or the receipt by the Collateral Agent or any Secured Party of any payment relating thereto, nor
shall the Collateral Agent or any Secured Party be obligated in any manner to perform any of the obligations of any Grantor under or pursuant to any Subject Account (or any agreement giving rise thereto), to make any payment, to make any inquiry as
to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts
which may have been assigned to it or to which it may be entitled at any time or times. 
 5.3. Proceeds to be Turned Over to Collateral
Agent. In addition to the rights of the Collateral Agent and the Secured Parties specified in Section 5.1 with respect to payments of Subject Accounts, if an Event of Default shall occur and be continuing and the Collateral Agent so
requires by notice in writing to the relevant Grantor (it being understood that the exercise of remedies by the Secured Parties pursuant to the Intercreditor Agreement in connection with an Event of Default under Section 11.5 of the Credit
Agreement shall be deemed to constitute a request by the Collateral Agent for the purposes of this sentence and in such circumstances, no such written notice shall be required), all Proceeds received by any Grantor consisting of cash, checks and
other near-cash items shall be held by such Grantor in trust for the Collateral Agent and the Secured Parties, segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to the Collateral Agent in
the exact form received by such Grantor (duly endorsed by such Grantor to the Collateral Agent, if required). All Proceeds received by the Collateral Agent hereunder shall be held by the Collateral Agent in a Collateral Account maintained under its
dominion and control and on terms and conditions reasonably satisfactory to the Collateral Agent. All Proceeds while held by the Collateral Agent in a Collateral Account (or by such Grantor in trust for the Collateral Agent and the Secured Parties)
shall continue to be held as collateral security for all the Obligations and shall not constitute payment thereof until applied as provided in Section 5.4. 
 5.4. Application of Proceeds. The Collateral Agent shall apply the proceeds of any collection or sale of the Collateral as well as any Collateral consisting of cash, at any time after receipt in the order
specified in Section 4.1 of the Intercreditor Agreement. Upon any sale of the Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Collateral Agent or
of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to
the Collateral Agent or such officer or be answerable in any way for the misapplication thereof. 
 5.5. Code and Other Remedies. If
an Event of Default shall occur and be continuing, the Collateral Agent may exercise in respect of the Collateral, in addition to all other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a
secured party upon default under the UCC or any other applicable law and also may, with notice to the relevant Grantor, sell the Collateral or any part thereof in one or more parcels at one or more public or private sales, at any exchange,
broker’s board or office of the Collateral Agent or any Lender or elsewhere for cash or on credit or for future delivery at such price or prices and upon such other terms as are commercially reasonable irrespective of the impact of any such
sales on the market price of the Collateral. The Collateral Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers of Collateral to Persons who will represent and agree that
they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and, upon consummation of any such sale, the Collateral Agent shall have the right to assign, transfer and deliver to
the 

  

 -14- 

 
purchaser or purchasers thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right
on the part of any Grantor, and each Grantor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or
hereafter enacted. The Collateral Agent and any Secured Party shall have the right upon any such public sale, and, to the extent permitted by law, upon any such private sale, to purchase the whole or any part of the Collateral so sold, and the
Collateral Agent or such Secured Party may pay the purchase price by crediting the amount thereof against the Obligations. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such
Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale
having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so
adjourned. To the extent permitted by law, each Grantor hereby waives any claim against the Collateral Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price that
might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree. Each Grantor further agrees, at the Collateral Agent’s request to assemble the
Collateral and make it available to the Collateral Agent, at places which the Collateral Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. The Collateral Agent shall apply the net proceeds of any action taken by it
pursuant to this Section 5.5 in accordance with the provisions of Section 5.4. 
 5.6. Deficiency. Each Grantor shall remain
liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its Obligations and the reasonable and documented fees, disbursements and other charges of one firm of counsel and, if necessary,
one firm of regulatory counsel and/or one firm of local counsel in each appropriate jurisdiction, to the Administrative Agent and Collateral Agent (and, in the case of an actual or perceived conflict of interest where the Person affected by such
conflict informs the Company of such conflict and thereafter, after receipt of the consent of the Company (which consent shall not be unreasonably withheld or delayed), retains its own counsel, of another firm of counsel for such affected Person) to
collect such deficiency. 
 5.7. Amendments, etc. with Respect to the Obligations; Waiver of Rights. Each Grantor shall remain
obligated hereunder notwithstanding that, without any reservation of rights against any Grantor and without notice to or further assent by any Grantor, (a) any demand for payment of any of the Obligations made by the Collateral Agent or any
other Secured Party may be rescinded by such party and any of the Obligations continued, (b) the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset
with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Collateral Agent or any other Secured Party, (c) the Credit Agreement,
the other Credit Documents, the Letters of Credit and any other documents executed and delivered in connection therewith and any Secured Cash Management Agreements, Secured Hedging Agreements, and Secured Commodity Hedging Agreement and any other
documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders, as the case may be, or, in the case of any Secured Cash
Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement, the applicable Cash Management Bank or Hedge Bank) may deem advisable from time to time, and (d) any collateral security, guarantee or right of offset at
any time held by the Collateral Agent or any other Secured Party for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Collateral Agent nor any other Secured Party shall have any obligation to
protect, 

  

 -15- 

 
secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Security Agreement or any property subject thereto.
When making any demand hereunder against any Grantor, the Collateral Agent or any other Secured Party may, but shall be under no obligation to, make a similar demand on the Company or any Grantor or any other Person, and any failure by the
Collateral Agent or any other Secured Party to make any such demand or to collect any payments from the Company or any Grantor or any other Person or any release of the Company or any Grantor or any other Person shall not relieve any Grantor in
respect of which a demand or collection is not made or any Grantor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the
Collateral Agent or any other Secured Party against any Grantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings. 
 6. The Collateral Agent. 
 6.1.
Collateral Agent’s Appointment as Attorney-in-Fact, etc. 
 (a) Each Grantor hereby appoints, which appointment is irrevocable
and coupled with an interest, effective upon the occurrence and during the continuance of an Event of Default, the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, for the purpose of carrying out the terms of this Security Agreement, to take any and all appropriate action and to execute any and
all documents and instruments which may be necessary or desirable to accomplish the purposes of this Security Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Collateral Agent the power and right, on
behalf of such Grantor, either in the Collateral Agent’s name or in the name of such Grantor or otherwise, without assent by such Grantor, to do any or all of the following, in each case after the occurrence and during the continuance of an
Event of Default and after written notice by the Collateral Agent of its intent to do so: 
 (i) take possession of and
endorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Subject Account or with respect to any other Collateral and file any claim or take any other action or proceeding in any court of
law or equity or otherwise deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due under any Subject Account or with respect to any other Collateral whenever payable; 
 (ii) in the case of any Intellectual Property, execute and deliver, and have recorded, any and all agreements, instruments, documents and
papers as the Collateral Agent may reasonably request to evidence the Collateral Agent’s and the Secured Parties’ Security Interest in such Intellectual Property and the goodwill and general intangibles of such Grantor relating thereto or
represented thereby; 
 (iii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral;

 (iv) execute, in connection with any sale provided for in Section 5.5, any endorsements, assignments or other
instruments of conveyance or transfer with respect to the Collateral; 
  

 -16- 

 (v) obtain and adjust insurance required to be maintained by such Grantor pursuant to
Section 9.3 of the Credit Agreement; 
 (vi) direct any party liable for any payment under any of the Collateral to make
payment of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; 
 (vii) ask or demand for, collect and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; 
 (viii) sign and endorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors,
assignments, verifications, notices and other documents in connection with any of the Collateral; 
 (ix) commence and
prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; 
 (x) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral (with such Grantor’s consent to
the extent such action or its resolution could materially affect such Grantor or any of its Affiliates in any manner other than with respect to its continuing rights in such Collateral); 
 (xi) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as
the Collateral Agent may deem appropriate (with such Grantor’s consent to the extent such action or its resolution could materially affect such Grantor or any of its affiliates in any manner other than with respect to its continuing rights in
such Collateral); 
 (xii) assign any Intellectual Property (along with the goodwill of the business to which any such
Intellectual Property pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the Collateral Agent shall in its reasonable business discretion determine; and 
 (xiii) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and
completely as though the Collateral Agent were the absolute owner thereof for all purposes, and do, at the Collateral Agent’s option and such Grantor’s expense, at any time, or from time to time, all acts and things that the Collateral
Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent’s and the Secured Parties’ Security Interests therein and to effect the intent of this Security Agreement, all as fully and effectively as
such Grantor might do. 
 Anything in this Section 6.1(a) to the contrary notwithstanding, the Collateral Agent agrees that it will not exercise any
rights under the power of attorney provided for in this Section 6.1(a) unless an Event of Default shall have occurred and be continuing. 
  

 -17- 

 (b) If any Grantor fails to perform or comply with any of its agreements contained herein, the Collateral
Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement. 
 (c) The expenses of the Collateral Agent incurred in connection with actions undertaken as provided in this Section 6.1 (to the extent required to be reimbursed by the Grantors pursuant to the Credit Documents),
together with interest thereon at a rate per annum equal to the highest rate per annum at which interest would then be payable on any category of past due ABR Loans under the Credit Agreement, from the date of payment by the Collateral Agent to the
date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Collateral Agent on demand. 
 (d) Each Grantor hereby
ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Security Agreement are coupled with an interest and are irrevocable until this Security Agreement is
terminated and the Security Interests created hereby are released. 
 6.2. Duty of Collateral Agent. The Collateral Agent’s sole
duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar
property for its own account. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the
Collateral Agent accords its own property. Neither the Collateral Agent, any Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or
for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof.
The powers conferred on the Collateral Agent and the Secured Parties hereunder are solely to protect the Collateral Agent’s and the Secured Parties’ interests in the Collateral and shall not impose any duty upon the Collateral Agent or any
Secured Party to exercise any such powers. The Collateral Agent and the Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers,
directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct. 
 6.3. Authority of Collateral Agent. Each Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Security Agreement with respect to any action taken by the Collateral Agent
or the exercise or non-exercise by the Collateral Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as between the Collateral Agent and the
Secured Parties, be governed by the Credit Agreement, and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and the Grantors, the Collateral Agent shall be conclusively
presumed to be acting as agent for the applicable Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

 6.4. Security Interest Absolute. All rights of the Collateral Agent hereunder, the Security Interest and all obligations of the
Grantors hereunder shall be absolute and unconditional. 
  

 -18- 

 6.5. Continuing Security Interest; Assignments Under the Credit Agreement; Release. 
 (a) This Security Agreement shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Grantor and
the successors and assigns thereof and shall inure to the benefit of the Collateral Agent and the other Secured Parties and their respective successors, indorsees, transferees and assigns until all Secured Obligations (other than any contingent
indemnity obligations not then due) and the obligations of each Grantor under this Security Agreement shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding (or all such
Letters of Credit shall have been fully Cash Collateralized or otherwise back-stopped to the reasonable satisfaction of the applicable Letter of Credit Issuers), notwithstanding that from time to time during the term of the Credit Agreement and any
Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement the Credit Parties may be free from any Obligations. 
 (b) A Subsidiary Grantor shall automatically be released from its obligations hereunder and the Security Interest in the Collateral of such Subsidiary Grantor shall be automatically released upon the consummation of
any transaction permitted under the Credit Agreement as a result of which such Subsidiary Grantor ceases to be a Subsidiary Guarantor. 
 (c)
Upon any sale, transfer or other disposition by any Grantor of any Collateral that is permitted under the Credit Agreement or upon the effectiveness of any written consent to the release of the Security Interest granted hereby in any Collateral
pursuant to Section 13.1 of the Credit Agreement, the Security Interest in such Collateral shall be automatically released and such Collateral sold, transferred or disposed of free and clear of the Lien and Security Interests created hereby.

 (d) In connection with any termination or release pursuant to paragraph (a), (b) or (c), the Collateral Agent shall execute and
deliver to any Grantor, at such Grantor’s expense, all documents that such Grantor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 6.5 shall be without
recourse to or warranty by the Collateral Agent. 
 6.6. Reinstatement. Each Grantor further agrees that, if any payment made by any
Credit Party or other Person and applied to the Obligations is at any time annulled, avoided, set aside, rescinded, invalidated, declared to be fraudulent or preferential or otherwise required to be refunded or repaid, or the Proceeds of Collateral
are required to be returned by any Secured Party to such Credit Party, its estate, trustee, receiver or any other party, including any Grantor, under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of
such payment or repayment, any Lien or other Collateral securing such liability shall be and remain in full force and effect, as fully as if such payment had never been made or, if prior thereto the Lien granted hereby or other Collateral securing
such liability hereunder shall have been released or terminated by virtue of such cancellation or surrender), such Lien or other Collateral shall be reinstated in full force and effect, and such prior cancellation or surrender shall not diminish,
release, discharge, impair or otherwise affect any Lien or other Collateral securing the obligations of any Grantor in respect of the amount of such payment. 
 7. Collateral Agent as Agent. 
 (a) Citibank, N.A. has been appointed to act as the Collateral Agent
under the Credit Agreement, by the Lenders under the Credit Agreement and, by their acceptance of the benefits hereof, the other Secured Parties. The Collateral Agent shall be obligated, and shall have the right hereunder, to 

  

 -19- 

 
make demands, to give notices, to exercise or refrain from exercising any rights, and to take or refrain from taking any action (including the release or
substitution of Collateral), solely in accordance with this Security Agreement, the Credit Agreement and the Intercreditor Agreement, provided that the Collateral Agent shall exercise, or refrain from exercising, any remedies provided for in
Section 5 in accordance with the instructions of Required Secured Parties. In furtherance of the foregoing provisions of this Section 7(a), each Secured Party, by its acceptance of the benefits hereof, agrees that it shall have no
right individually to realize upon any of the Collateral hereunder, it being understood and agreed by such Secured Party that all rights and remedies hereunder may be exercised solely by the Collateral Agent for the benefit of the applicable Secured
Parties in accordance with the terms of this Section 7(a). 
 (b) The Collateral Agent shall at all times be the same Person that is the
Collateral Agent under the Credit Agreement. Written notice of resignation by the Collateral Agent pursuant to Section 12.9 of the Credit Agreement shall also constitute notice of resignation as Collateral Agent under this Security Agreement;
removal of the Collateral Agent shall also constitute removal under this Security Agreement; and appointment of a Collateral Agent pursuant to Section 12.9 of the Credit Agreement shall also constitute appointment of a successor Collateral
Agent under this Security Agreement. Upon the acceptance of any appointment as Collateral Agent under Section 12.9 of the Credit Agreement by a successor Collateral Agent, that successor Collateral Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring or removed Collateral Agent under this Security Agreement, and the retiring or removed Collateral Agent under this Security Agreement shall promptly (i) transfer to such
successor Collateral Agent all sums, securities and other items of Collateral held hereunder, together with all records and other documents necessary or appropriate in connection with the performance of the duties of the successor Collateral Agent
under this Security Agreement, and (ii) execute and deliver to such successor Collateral Agent or otherwise authorize the filing of such amendments to financing statements and take such other actions, as may be necessary or appropriate in
connection with the assignment to such successor Collateral Agent of the Security Interests created hereunder, whereupon such retiring or removed Collateral Agent shall be discharged from its duties and obligations under this Security Agreement.
After any retiring or removed Collateral Agent’s resignation or removal hereunder as Collateral Agent, the provisions of this Security Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it under this Security
Agreement while it was Collateral Agent hereunder. 
 (c) The Collateral Agent shall not be deemed to have any duty whatsoever with respect
to any Secured Party that is a counterparty to a Secured Cash Management Agreement, Secured Commodity Hedging Agreement or Secured Hedging Agreement the obligations under which constitute Obligations, unless it shall have received written notice in
form and substance satisfactory to the Collateral Agent from a Grantor or any such Secured Party as to the existence and terms of the applicable Secured Cash Management Agreement, Secured Commodity Hedging Agreement or Secured Hedging Agreement, it
being agreed by the Collateral Agent that delivery of a duly executed Accession Agreement pursuant to the terms of the Intercreditor Agreement shall comply with the requirements of this clause (c). 
 8. Miscellaneous. 
 8.1.
Amendments in Writing. None of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the affected Grantor and the Collateral Agent in
accordance with Section 13.1 of the Credit Agreement. 
  

 -20- 

 8.2. Notices. All notices, requests and demands pursuant hereto shall be made in accordance with
Section 13.2 of the Credit Agreement. All communications and notices hereunder to any Subsidiary Grantor shall be given to it in care of the Company at the Company’s address set forth in Section 13.2 of the Credit Agreement.

 8.3. No Waiver by Course of Conduct; Cumulative Remedies. Neither the Collateral Agent nor any Secured Party shall by any act
(except by a written instrument pursuant to Section 8.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the
terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent or any other Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent or any other Secured Party of any right or remedy
hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Collateral Agent or such other Secured Party would otherwise have on any future occasion. The rights, remedies, powers and privileges herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law. 
 8.4.
Enforcement Expenses; Indemnification. 
 (a) Each Grantor agrees to pay any and all reasonable and documented out-of-pocket costs and

Subsidiaries, for the repayment of any amounts payable pursuant to the Credit Documents or any Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement and for satisfaction of any other Obligations owing to
the Secured Parties under the Credit Documents or any Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement, and (vi) that none of Oncor Holdings or its Subsidiaries shall be personally liable to
the Secured Parties for any amounts payable, or any other liability, under the Credit Documents or any Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement. 
 (b) The Collateral Agent, on behalf of itself and the Secured Parties, shall not (i) initiate any legal proceeding to procure the appointment of an

(as defined in the First Amendment to Lease Agreement) dated as of June 1, 2007 between U.S. Bank, N.A. (as successor-in-interest to State Street Bank and Trust Company of Connecticut, National Association), as owner trustee of the ZSF/Dallas

Liens; TO HAVE AND TO HOLD the Mortgaged Property 

  

 4 

 
together with the rights, privileges and appurtenances thereto belonging to Trustee and to its substitutes or successors, forever; and Grantor does hereby
bind itself, its successors and assigns to WARRANT AND FOREVER DEFEND the title to the Mortgaged Property, subject to Permitted Liens, unto Trustee and to its substitutes or successors against the claim or claims of every person whomsoever lawfully
claiming or to claim the same or any part thereof. 
 TO HAVE AND TO HOLD the Mortgaged Property unto the Trustee and/or Beneficiary, their
respective successors and assigns for the uses and purposes set forth, until the Obligations are fully paid and performed, provided, however, that the condition of this Deed of Trust is such that if the Obligations are fully paid and performed in
accordance with the provisions of the Credit Agreement, then the estate hereby granted shall cease, terminate and become void but shall otherwise remain in full force and effect. 
  

	3.	WARRANTIES, REPRESENTATIONS AND COVENANTS 

 Grantor warrants,
represents and covenants to Trustee as follows: 
 3.1 Title to Mortgaged Property and Lien of this Instrument. Grantor warrants that
Grantor has good title in fee simple in and to the Warranty Land, a valid leasehold estate under the Mortgaged Leases described in Exhibit B, a valid easement estate under the Warranty Easements Rights, and good title to the Warranty Fee
Improvements, the Warranty Leasehold Improvements and the Warranty Easement Improvements, the Warranty Fixtures and the Warranty Water Rights, and upon acquisition thereof by Grantor, will have good title in fee simple, leasehold or easement estate,
as applicable, in the portion of the Mortgage Property hereafter acquired by Grantor, in each case free and clear of any Liens except for Permitted Liens, except where the failure to have such good title could not reasonably be expected to have a
Material Adverse Effect. This Deed of Trust creates valid, enforceable first priority liens and security interests against the Mortgaged Property, subject to Permitted Liens, and upon recording of this Deed of Trust in the real property records of
the county or counties in which the Mortgaged Property is situated and this Deed of Trust being indexed as a fixture, timber and as-extracted collateral filing in such records, this Deed of Trust will create and constitute a valid and enforceable
first priority mortgage Lien on and UCC security interest in the portion of the Mortgaged Property that is fixtures, timber to be cut and as-extracted collateral, subject to Permitted Liens. Grantor shall preserve and protect the Lien (including the
priority thereof) and security interest of this Deed of Trust and the other Security Documents insofar as they refer to the Mortgaged Property, subject only to Permitted Liens, to the extent necessary to avoid causing a Material Adverse Effect.

 3.2 Payment of Obligations. Grantor shall pay and perform the Obligations at the times and places and in the manner specified in
the Credit Documents. 
 3.3 Requirements. Grantor shall comply with all covenants, restrictions and conditions now or later of record
which may be applicable to any of the Mortgaged Property, or to the use, manner of use, occupancy, possession, operation, maintenance, alteration, repair or reconstruction of any of the Mortgaged Property, except where a failure to do so could not
reasonably be expected to have a Material Adverse Effect. 
  

 5 

 3.4 Payment of Taxes and Other Impositions. (a) Except as may be permitted by the Credit
Agreement, Grantor shall, prior to the date on which any fine, penalty, interest or cost may be added thereto or imposed, pay and discharge all taxes, charges and assessments of every kind and nature, all charges for any easement or agreement
maintained for the benefit of any of the Real Estate, all general and special assessments, levies, permits, inspection and license fees, all water and sewer rents and charges, all vault taxes and all other public charges even if unforeseen or
extraordinary, imposed upon or assessed against or that may become a material lien on any of the Real Estate, or arising in respect of the occupancy, use or possession thereof, together with any penalties or interest on any of the foregoing (all of
the foregoing are collectively referred to herein as the “Impositions”), except where the validity or amount thereof is being contested in good faith and by proper proceedings, so long as Grantor maintains adequate reserves (in the
good faith judgment of the management of the Borrower) with respect thereto in accordance with GAAP and the failure to pay could not reasonably be expected to result in a Material Adverse Effect. If by law any Imposition may be paid in installments
(whether or not interest shall accrue on the unpaid balance of such Imposition), Grantor may elect to pay such Imposition in such installments and shall be responsible for the payment of such installments with interest, if any. 
 (b) Nothing herein shall affect any right or remedy of Trustee or Beneficiary under this Deed of Trust or otherwise, following the occurrence and during
the continuance of an Event of Default, without notice or demand to Grantor, to pay any Imposition after the date such Imposition shall have become delinquent, and add to the Obligations the amount so paid, together with interest from the time of
payment at the Default Rate. Any sums paid by Trustee or Beneficiary in discharge of any Impositions shall be (i) a lien on the Premises secured hereby prior to any right or title to, interest in, or claim upon the Premises subordinate to the
lien of this Deed of Trust, and (ii) payable on demand by Grantor to Trustee or Beneficiary, as the case may be, together with interest at the Default Rate. 
 3.5 Insurance. Mortgagor will keep or cause to be kept the Mortgaged Property insured against such risks and shall purchase such additional insurance to the extent that is required from time to time pursuant to
Section 9.3 of the Credit Agreement. 
 3.6 Restrictions on Liens and Encumbrances. Except for the lien of this Deed of Trust and
the Permitted Liens, Grantor shall not further mortgage, nor otherwise encumber the Mortgaged Property nor create or suffer to exist any lien, charge or encumbrance on the Mortgaged Property, or any part thereof, whether superior or subordinate to
the lien of this Deed of Trust and whether recourse or non-recourse. 
 3.7 Due on Sale and Other Transfer Restrictions. Except as
expressly permitted under the Credit Agreement or herein, Grantor shall not sell, transfer, convey or assign all or any portion of, or any interest in, the Mortgaged Property. 
 3.8 Condemnation/Eminent Domain. Promptly upon obtaining knowledge of the institution of any proceedings for the condemnation of the Mortgaged
Property, or any material portion thereof, Grantor will notify Beneficiary of the pendency of such proceedings. All awards and proceeds relating to such condemnation shall be deemed proceeds from a Recovery Prepayment Event and applied in the manner
specified in the Credit Agreement. 
  

 6 

 3.9 Leases. Except as expressly permitted under the Credit Agreement, Grantor shall not
(a) execute an assignment or pledge of any Lease relating to all or any portion of the Mortgaged Property other than in favor of Beneficiary, or (b) execute or permit to exist any Lease (other than a Lease of the type described in clause
(k) of the definition of Permitted Liens) of any of the Mortgaged Property. 
 3.10 Further Assurances. To the extent required
under the terms of the Credit Agreement, to further assure Beneficiary’s rights under this Deed of Trust, Grantor agrees promptly upon demand of Beneficiary to do any act or execute any additional documents (including, but not limited to,
security agreements on any personalty included or to be included in the Mortgaged Property and a separate assignment of each Lease in recordable form) as may be reasonably required by Beneficiary to confirm the lien of this Deed of Trust and all
other rights or benefits conferred on Beneficiary by this Deed of Trust. 
 3.11 Beneficiary’s Right to Perform. Upon the
occurrence and during the continuance of an Event of Default, Beneficiary or Trustee, may, at any time upon 5 days’ notice to Grantor (but shall be under no obligation to) pay or perform any delinquent obligations of Grantor hereunder, and the
amount or cost thereof, with interest at the Default Rate, shall immediately be due from Grantor to Beneficiary or Trustee (as the case may be) and the same shall be secured by this Deed of Trust and shall be a lien on the Mortgaged Property prior
to any right, title to, interest in, or claim upon the Mortgaged Property attaching subsequent to the lien of this Deed of Trust. No payment or advance of money by Beneficiary or Trustee under this Section shall be deemed or construed to cure
Grantor’s default or waive any right or remedy of Beneficiary or Trustee. 
  

	4.	LIMITATION ON AMOUNT OBLIGATED; CONTRIBUTION BY OTHER PERSONS 

 Anything contained in this Deed of Trust to the contrary notwithstanding, if any Fraudulent Transfer Law (as hereinafter defined) is determined by a court of competent jurisdiction to be applicable to the obligations
of Grantor under this Deed of Trust, such obligations shall be limited to the maximum aggregate amount that would not render Grantor’s obligations under this Deed of Trust subject to avoidance as a fraudulent transfer or conveyance under
Section 548 of Title 11 of the United States Code or any applicable provisions of comparable state law (collectively, the “Fraudulent Transfer Laws”), in each case after giving effect to all other liabilities of Grantor,
contingent or otherwise, that are relevant under the Fraudulent Transfer Laws, and giving effect as assets to the value (as determined under the applicable provisions of the Fraudulent Transfer Laws) of any rights to subrogation, reimbursement,
indemnification, or contribution of Grantor pursuant to applicable law or pursuant to the terms of any agreement. 
  

 7 

	5.	REMEDIES 

 (a) Upon the occurrence and during the
continuance of any Event of Default, Beneficiary may immediately take such action, without notice or demand, as it deems advisable to protect and enforce its rights against Grantor and in and to the Mortgaged Property, including, but not limited to,
the following actions, each of which may be pursued concurrently or otherwise, at such time and in such manner as Trustee or Beneficiary (as the case may be) may determine, in its sole discretion, without impairing or otherwise affecting the other
rights and remedies of Beneficiary: 
 (i) Upon the occurrence and during the continuance of an Event of Default, Trustee is
hereby authorized and empowered to sell or offer for sale at one or more sales, as an entirety or in parcels, as Trustee may elect, all or any part of the Mortgaged Property located in the State of Texas, with or without having first taken
possession of same, to the highest bidder for cash at public auction. Such sale or sales shall be made at the courthouse of the county in Texas in which the Mortgaged Property or any part thereof is situated, as herein described, between the hours
of 10:00 a.m. and 4:00 p.m. on the first Tuesday of any month, beginning within three (3) hours of the time provided in the notices described herein. Trustee shall post a written or printed notice or notices of the place, earliest time at which
the sale will begin and the terms of said sale, and the portion of the Mortgaged Property to be sold, for at least twenty-one (21) days preceding the date of the sale, at the courthouse door of said county in which the sale is to be made; and
if such Mortgaged Property lies in more than one county, one such notice of sale shall be posted at the courthouse door of each county in which such Mortgaged Property is situated and such Mortgaged Property may be sold at the area designated by the
commissioners court of any one of such counties, and the notice so posted shall designate in which county such property shall be sold. In addition to such posting of notice, Beneficiary, Trustee or the other holder of the secured indebtedness (or
some person or persons acting for the Trustee, Beneficiary, or other such holder) shall, at least twenty-one (21) days preceding the date of sale, file a copy of such notice(s) in the office of the county clerk in each of such counties and
serve or cause to be served written notice of the proposed sale by certified mail on Grantor and on each other party, if any, obligated to pay the secured indebtedness according to the records of Beneficiary. Service of such notice shall be
completed upon deposit of the notice, enclosed in a postpaid wrapper properly addressed to Grantor and such other parties at their most recent address or addresses as shown by the records of Beneficiary, in a post office or official depository under
the care and custody of the United States Postal Service. The affidavit of any person having knowledge of the facts to the effect that such a service was completed shall be prima facie evidence of the fact of service. Grantor agrees that no notice
of any sale, other than as set out in this paragraph, need be given by Trustee, Beneficiary, or any other person. Grantor authorizes and empowers Trustee to sell the Mortgaged Property in lots or parcels or in its entirety as Trustee shall deem
expedient; and to execute and deliver to the purchaser or purchasers thereof good and sufficient deeds of conveyance thereto, with evidence of general warranty by Grantor. Trustee may postpone the sale of all or any part of the Mortgaged Property by
public announcement at the time and place of such sale, and from time to time thereafter may further postpone such sale by public announcement made at the time of sale fixed by the preceding postponement. The right of sale hereunder shall not be
exhausted by one or any sale, and Trustee may make other and successive sales until all of the trust estate be legally sold. The provisions hereof with respect to the posting and giving of notices of sale are intended to comply with the provisions
of Section 51.002 of the Texas Property Code as in effect on the date hereof, and in the event that the requirements of Section 51.002 of the Texas Property Code shall be modified or repealed in the future, by amendment, superceding
statute or otherwise, and such amendment, statute or other action applies to the enforcement of pre-existing instruments, then the terms of this Section shall be deemed to be modified accordingly, effective as of the effective date of such
modification or repeal; 
  

 8 

 (ii) Beneficiary may, to the extent permitted by applicable law, (A) institute and
maintain an action of mortgage foreclosure against all or any part of the Mortgaged Property, (B) institute and maintain an action on the Credit Documents, or (C) take such other action at law or in equity for the enforcement of this Deed
of Trust or any of the Credit Documents as the law may allow. Beneficiary may proceed in any such action to final judgment and execution thereon for all sums due hereunder, together with interest thereon at the Default Rate and all costs of suit,
including, without limitation, reasonable attorneys’ fees and disbursements. Interest at the Default Rate, to the extent permitted by applicable law, shall be due on any judgment obtained by Beneficiary from the date of judgment until actual
payment is made of the full amount of the judgment; and 
 (iii) Beneficiary may personally, or by its agents, attorneys and
employees and without regard to the adequacy or inadequacy of the Mortgaged Property or any other collateral as security for the Obligations enter into and upon the Mortgaged Property and each and every part thereof and exclude Grantor and its
agents and employees therefrom without liability for trespass, damage or otherwise (Grantor hereby agreeing to surrender possession of the Mortgaged Property to Beneficiary upon demand at any such time) and use, operate, manage, maintain and control
the Mortgaged Property and every part thereof. Following such entry and taking of possession, Beneficiary shall be entitled, without limitation, (x) to lease all or any part or parts of the Mortgaged Property for such periods of time and upon
such conditions as Beneficiary may, in its discretion, deem proper, (y) to enforce, cancel or modify any Lease and (z) generally to execute, do and perform any other act, deed, matter or thing concerning the Mortgaged Property as
Beneficiary shall deem appropriate as fully as Grantor might do. 
 (b) In case of a foreclosure sale, the Real Estate may be sold, at
Trustee’s election, in one parcel or in more than one parcel and Trustee is specifically empowered (without being required to do so, and in its sole and absolute discretion) to cause successive sales of portions of the Mortgaged Property to be
held. 
 (c) In the event of any breach of any of the covenants, agreements, terms or conditions contained in this Deed of Trust,
Beneficiary, and to the extent permitted by applicable law and principles of equity, shall be entitled to enjoin such breach and obtain specific performance of any covenant, agreement, term or condition and Beneficiary shall have the right to invoke
any equitable right or remedy as though other remedies were not provided for in this Deed of Trust. 
 (d) It is agreed that if an Event of
Default shall occur and be continuing, any and all proceeds of the Mortgaged Property received by Trustee or Beneficiary shall be held by Trustee for the Beneficiary for the benefit of the Secured Parties or by the Beneficiary for the benefit of the
Secured Parties as collateral security for the Obligations (whether matured or unmatured), and shall be applied in payment of the Obligations in the manner set forth in Section 5.4 of the Security Agreement.

	6.	RIGHT OF BENEFICIARY TO CREDIT SALE 

 Upon the
occurrence of any sale made under this Deed of Trust, whether made under the power of sale or by virtue of judicial proceedings or of a judgment or decree of foreclosure and sale, Beneficiary may bid for and acquire the Mortgaged Property or any
part thereof. In lieu of paying cash therefor, Beneficiary may make settlement for the purchase price by crediting upon the Obligations or other sums secured by this Deed of Trust, the net sales price after deducting therefrom the expenses of sale
and the cost of the action and any other sums which Beneficiary is authorized to deduct under this Deed of Trust. In such event, this Deed of Trust, the Credit Agreement, the Security Agreement and all other documents evidencing expenditures secured
hereby may be presented to the person or persons conducting the sale in order that the amount so used or applied may be credited upon the Obligations as having been paid. 
  

	7.	APPOINTMENT OF RECEIVER 

 If an Event of Default
shall have occurred and be continuing, Beneficiary as a matter of right and without notice to Grantor, unless otherwise required by applicable law, and without regard to the adequacy or inadequacy of the Mortgaged Property or any other collateral or
the interest of Grantor therein as security for the Obligations, shall have the right to apply to any court having jurisdiction to appoint a receiver or receivers of the Mortgaged Property, without requiring the posting of a surety bond, and without
reference to the adequacy of the value of the Mortgaged Property or the solvency or insolvency of Grantor or any other party obligated for payment of all or any part of the Obligations, and whether or not waste has occurred with respect to the
Mortgaged Property, and Grantor hereby irrevocably consents to such appointment and waives notice of any application therefor (except as may be required by law). Any such receiver or receivers shall have all the usual powers and duties of receivers
in like or similar cases and all the powers and duties of Beneficiary in case of entry as provided in this Deed of Trust, including, without limitation and to the extent permitted by law, the right to enter into leases of all or any part of the
Mortgaged Property, and shall continue as such and exercise all such powers until the date of confirmation of sale of the Mortgaged Property unless such receivership is sooner terminated. 
  

	8.	EXTENSION, RELEASE, ETC 

 (a) Without affecting the
lien or charge of this Deed of Trust upon any portion of the Mortgaged Property not then or theretofore released as security for the full amount of the Obligations, Beneficiary may, from time to time and without notice, agree to (i) release any
person liable for the indebtedness borrowed or guaranteed under the Credit Documents, (ii) extend the maturity or alter any of the terms of the indebtedness borrowed or guaranteed under the Credit Documents or any other guaranty thereof,
(iii) grant other indulgences, (iv) release or reconvey, or cause to be released or reconveyed at any time at Beneficiary’s option any parcel, portion or all of the Mortgaged Property, (v) take or release any other or additional
security for any obligation herein mentioned, or (vi) make compositions or other arrangements with debtors in relation thereto. 
 (b)
No recovery of any judgment by Beneficiary and no levy of an execution under any judgment upon the Mortgaged Property or upon any other property of Grantor shall affect the lien of this Deed of Trust or any liens, rights, powers or remedies of
Beneficiary hereunder, and such liens, rights, powers and remedies shall continue unimpaired. 
  

 10 

 (c) If Beneficiary shall have the right to foreclose this Deed of Trust or to direct the Trustee to
exercise its power of sale, Grantor authorizes Beneficiary at its option to foreclose the lien of this Deed of Trust (or direct the Trustee to sell the Mortgaged Property, as the case may be) subject to the rights of any tenants of the Mortgaged
Property. The failure to make any such tenants parties defendant to any such foreclosure proceeding and to foreclose their rights, or to provide notice to such tenants as required in any statutory procedure governing a sale of the Mortgaged
Property, or to terminate such tenant’s rights in such sale will not be asserted by Grantor as a defense to any proceeding instituted by Beneficiary to collect the Obligations or to foreclose the lien of this Deed of Trust. 
 (d) Unless expressly provided otherwise, in the event that Beneficiary’s interest in this Deed of Trust and title to the Mortgaged Property or any
estate therein shall become vested in the same person or entity, this Deed of Trust shall not merge in such title but shall continue as a valid lien on the Mortgaged Property for the amount secured hereby. 
  

	9.	SECURITY AGREEMENT UNDER UNIFORM COMMERCIAL CODE; FIXTURE FILING 

 (a) It is the intention of the parties hereto that this Deed of Trust shall constitute a “security agreement” within the meaning of the UCC. To that end, Grantor hereby grants to Trustee and Beneficiary, for
the ratable benefit of the Secured Parties, a security interest in the Fixtures, Leases, Rents, timber to be cut and as-extracted collateral, all to secure payment and performance of the Obligations. If an Event of Default shall occur and be
continuing, then in addition to having any other right or remedy available at law or in equity, Beneficiary shall have the option of either (i) proceeding under the UCC and exercising such rights and remedies as may be provided to a secured
party by the UCC with respect to all or any portion of the Mortgaged Property that is personal property (including, without limitation, taking possession of and selling such property) or (ii) treating such property as real property and
proceeding with respect to both the real and personal property constituting the Mortgaged Property in accordance with Beneficiary’s rights, powers and remedies with respect to the Real Estate (in which event the default provisions of the UCC
shall not apply). If Beneficiary shall elect to proceed under the UCC, then ten (10) days’ notice of sale of the personal property shall be deemed reasonable notice and the reasonable expenses of retaking, holding, preparing for sale,
selling and the like incurred by Beneficiary shall include, but not be limited to, attorneys’ fees and legal expenses. At Beneficiary’s request, Grantor shall assemble the personal property and make it available to Beneficiary at a place
designated by Beneficiary which is reasonably convenient to both parties. 
 (b) Certain portions of the Mortgaged Property are or will
become “fixtures”, “timber to be cut” or “as-extracted collateral” (as defined in the UCC) on the Owned Land, the Mortgage Leased Land, the Easement Land or the Improvements located thereon, and this Deed of Trust, upon
being filed for record in the real estate records of the county wherein such fixtures, timber to be cut or as-extracted collateral are situated, shall operate also as a financing statement filed as a fixture filing in accordance with the applicable
provisions of said UCC upon such portions of the Mortgaged Property that are or become fixtures. The Land, Mortgaged Leased Land and 

  

 11 

 
Easement Land to which the fixtures relate is described in Exhibit A, Exhibit B and Exhibit C respectively hereto. The record owner of
(i) the Land described in Exhibit A hereto is the Grantor, (ii) the Mortgaged Leased Land described in Exhibit B hereto is the landlord under the Mortgaged Leases described in such exhibit or its successor in interest as
owner of the Mortgaged Leased Land, and (iii) the Easement Land described in Exhibit C hereto is grantor of the Easement Rights described in such exhibit or its successor in interest as owner of the Easement Land. The name, type of
organization and jurisdiction of organization of the debtor for purposes of this financing statement are the name, type of organization and jurisdiction of organization of the Grantor set forth in the first paragraph of this Deed of Trust, and the
name of the secured party for purposes of this financing statement is the name of the Beneficiary set forth in the first paragraph of this Deed of Trust. The mailing address of the Grantor/debtor is the address of the Grantor set forth in the first
paragraph of this Deed of Trust. The mailing address of the Beneficiary/secured party from which information concerning the security interest hereunder may be obtained is the address of the Beneficiary set forth in the first paragraph of this Deed
of Trust. Grantor’s organizational identification number is set forth in the first paragraph of this Deed of Trust. 
  

	10.	ASSIGNMENT OF RENTS 

 (a) Grantor hereby assigns to
Beneficiary the Rents as further security for the payment of and performance of the Obligations, and Grantor grants to Beneficiary the right to enter the Mortgaged Property for the purpose of collecting the same and to let the Mortgaged Property or
any part thereof, and to apply the Rents on account of the Obligations. The foregoing assignment and grant is present and absolute and shall continue in effect until the Obligations are fully paid and performed, but Beneficiary hereby waives the
right to enter the Mortgaged Property for the purpose of collecting the Rents and Grantor shall be entitled to collect, receive, use and retain the Rents unless an Event of Default has occurred and for so long as such Event of Default continues;
such right of Grantor to collect, receive, use and retain the Rents may be revoked by Beneficiary upon the occurrence and during the continuance of any Event of Default by giving not less than five days’ written notice of such revocation to
Grantor. In the event such notice is given, Grantor shall pay over to Beneficiary, or to any receiver appointed to collect the Rents, any lease security deposits, and shall pay monthly in advance to Beneficiary, or to any such receiver, the fair and
reasonable rental value as determined by Beneficiary for the use and occupancy of such part of the Mortgaged Property as may be in the possession of Grantor or any affiliate of Grantor, and upon default in any such payment Grantor and any such
affiliate will vacate and surrender the possession of the Mortgaged Property to Beneficiary or to such receiver, and in default thereof may be evicted by summary proceedings or otherwise. Grantor shall not accept prepayments of installments of Rent
to become due for a period of more than one month in advance (except for security deposits and estimated payments of percentage rent, if any). 
 (b) Grantor has not affirmatively done any act that would prevent Beneficiary from, or limit Beneficiary in, acting under any of the provisions of the foregoing assignment. 
 (c) Except for any matter disclosed in the Credit Agreement, no action has been brought or, so far as is known to Grantor, is threatened, that would
interfere in any way with the right of Grantor to execute the foregoing assignment and perform all of Grantor’s obligations contained in this Section and in the Leases. 
  

 12 

	11.	ADDITIONAL RIGHTS 

 The holder of any subordinate
lien or subordinate deed of trust on the Mortgaged Property shall have no right to terminate any Lease whether or not such Lease is subordinate to this Deed of Trust nor shall Grantor consent to any holder of any subordinate lien or subordinate deed
of trust joining any tenant under any Lease in any trustee’s sale or action to foreclose such subordinate lien or modify, interfere with, disturb or terminate the rights of any tenant under any Lease. By recordation of this Deed of Trust all
subordinate lienholders and the trustees and beneficiaries under subordinate mortgages are subject to and notified of this provision, and any action taken by any such lienholder or beneficiary contrary to this provision shall be null and void. Any
such application shall not be construed to cure or waive any Default or Event of Default or invalidate any act taken by Beneficiary on account of such Default or Event of Default. 
  

	12.	NOTICES 

 All notices, requests and demands to or
upon the Beneficiary or the Grantor hereunder shall be effected in the manner provided for in Section 13.2 of the Credit Agreement; provided that any such notice, request or demand to or upon Grantor shall be addressed to Grantor at its address
set forth above. 
  

	13.	NO ORAL MODIFICATION 

 This Deed of Trust may not be
amended, supplemented or otherwise modified except in accordance with the provisions of Section 13.1 of the Credit Agreement. Any agreement made by Grantor and Beneficiary after the date of this Deed of Trust relating to this Deed of Trust
shall be superior to the rights of the holder of any intervening or subordinate lien or encumbrance. Trustee’s execution of any written agreement between Grantor and Beneficiary shall not be required for the effectiveness thereof as between
Grantor and Beneficiary. 
  

	14.	PARTIAL INVALIDITY 

 In the event any one or more of
the provisions contained in this Deed of Trust shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision hereof, but each shall be
construed as if such invalid, illegal or unenforceable provision had never been included. Notwithstanding anything to the contrary contained in this Deed of Trust or in any provisions of any Credit Document, the obligations of Grantor and of any
other obligor under any Credit Documents shall be subject to the limitation that Beneficiary shall not charge, take or receive, nor shall Grantor or any other obligor be obligated to pay to Beneficiary, any amounts constituting interest in excess of
the maximum rate permitted by law to be charged by Beneficiary. 
  

 13 

	15.	GRANTOR’S WAIVER OF RIGHTS 

 (a) Grantor hereby
voluntarily and knowingly releases and waives any and all rights to retain possession of the Mortgaged Property upon the occurrence and during the continuance of an Event of Default and any and all rights of redemption from sale under any order or
decree of foreclosure (whether full or partial), pursuant to rights, if any, therein granted, as allowed under any applicable law, on its own behalf, on behalf of all persons claiming or having an interest (direct or indirectly) by, through or under
Grantor and on behalf of each and every person acquiring any interest in the Mortgaged Property subsequent to the date hereof, it being the intent hereof that any and all such rights of redemption of Grantor and all such other persons are and shall
be deemed to be hereby waived to the fullest extent permitted by applicable law or replacement statute. To the fullest extent permitted by applicable law, Grantor shall not invoke or utilize any such law or laws or otherwise hinder, delay, or impede
the execution of any right, power, or remedy herein or otherwise granted or delegated to Beneficiary, but shall permit the execution of every such right, power, and remedy as though no such law or laws had been made or enacted. 
 (b) To the fullest extent permitted by law, Grantor waives the benefit of all laws now existing or that may subsequently be enacted providing for
(i) any appraisement before sale of any portion of the Mortgaged Property, (ii) any extension of the time for the enforcement of the collection of the Obligations or the creation or extension of a period of redemption from any sale made in
collecting such debt and (iii) exemption of the Mortgaged Property from attachment, levy or sale under execution or exemption from civil process. To the full extent Grantor may do so, Grantor agrees that Grantor will not at any time insist
upon, plead, claim or take the benefit or advantage of any law now or hereafter in force providing for any appraisement, valuation, stay, exemption, extension or redemption, or requiring foreclosure of this Deed of Trust before exercising any other
remedy granted hereunder and Grantor, for Grantor and its successors and assigns, and for any and all persons ever claiming any interest in the Mortgaged Property, to the extent permitted by law, hereby waives and releases all rights of redemption,
valuation, appraisement, stay of execution, notice of election to mature (except as expressly provided in the Credit Agreement) or declare due the whole of the secured indebtedness and marshalling in the event of exercise by Trustee or Beneficiary
of the foreclosure rights, power of sale, or other rights hereby created. 
  

	16.	REMEDIES NOT EXCLUSIVE 

 Beneficiary and Trustee
shall be entitled to enforce payment and performance of the Obligations and to exercise all rights and powers under this Deed of Trust or under any of the other Credit Documents or other agreement or any laws now or hereafter in force,
notwithstanding some or all of the Obligations may now or hereafter be otherwise secured, whether by deed of trust, mortgage, security agreement, pledge, lien, assignment or otherwise. Neither the acceptance of this Deed of Trust nor its
enforcement, shall prejudice or in any manner affect Beneficiary’s or Trustee’s right to realize upon or enforce any other security now or hereafter held by Beneficiary or Trustee, it being agreed that Beneficiary and Trustee shall be
entitled to enforce this Deed of Trust and any other security now or hereafter held by Beneficiary or Trustee in such order and manner as Beneficiary or Trustee may determine in its absolute discretion. No remedy herein conferred upon or reserved to
Trustee or Beneficiary is intended to 

  

 14 

 
be exclusive of any other remedy herein or by law provided or permitted, but each shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute. Every power or remedy given by any of the Credit Documents to Beneficiary or Trustee or to which either may otherwise be entitled, may be exercised, concurrently or
independently, from time to time and as often as may be deemed expedient by Beneficiary or Trustee, as the case may be. In no event shall Beneficiary or Trustee, in the exercise of the remedies provided in this Deed of Trust (including, without
limitation, in connection with the assignment of Rents to Beneficiary, or the appointment of a receiver and the entry of such receiver on to all or any part of the Mortgaged Property), be deemed a “mortgagee in possession,” and neither
Beneficiary nor Trustee shall in any way be made liable for any act, either of commission or omission, in connection with the exercise of such remedies. 
  

	17.	MULTIPLE SECURITY 

 If (a) the Land shall
consist of one or more parcels, whether or not contiguous and whether or not located in the same county, or (b) in addition to this Deed of Trust, Beneficiary shall now or hereafter hold or be the beneficiary of one or more additional
mortgages, liens, deeds of trust or other security (directly or indirectly) for the Obligations upon other property in the State in which the Land is located (whether or not such property is owned by Grantor or by others) or (c) both the
circumstances described in clauses (a) and (b) shall be true, then to the fullest extent permitted by law, and after giving all notices required by law, Beneficiary may, at its election, commence or consolidate in a single trustee’s
sale or foreclosure action all trustee’s sale or foreclosure proceedings against all such collateral securing the Obligations (including the Mortgaged Property), which action may be brought or consolidated in the courts of, or sale conducted
in, any county in which any of such collateral is located. Grantor acknowledges that the right to maintain a consolidated trustee’s sale or foreclosure action is a specific inducement to Beneficiary to extend the indebtedness borrowed pursuant
to or guaranteed by the Credit Documents, and Grantor expressly and irrevocably waives any objections to the commencement or consolidation of the foreclosure proceedings in a single action and any objections to the laying of venue or based on the
grounds of forum non conveniens which it may now or hereafter have. Grantor further agrees that if Trustee or Beneficiary shall be prosecuting one or more foreclosure or other proceedings against a portion of the Mortgaged Property or against any
collateral other than the Mortgaged Property, which collateral directly or indirectly secures the Obligations, or if Beneficiary shall have obtained a judgment of foreclosure and sale or similar judgment against such collateral (or, in the case of a
trustee’s sale, shall have met the statutory requirements therefor with respect to such collateral), then, whether or not such proceedings are being maintained or judgments were obtained in or outside the State in which the Premises are
located, Beneficiary may commence or continue any foreclosure proceedings and exercise its other remedies granted in this Deed of Trust against all or any part of the Mortgaged Property and Grantor waives any objections to the commencement or
continuation of a foreclosure of this Deed of Trust or exercise of any other remedies hereunder based on such other proceedings or judgments, and waives any right to seek to dismiss, stay, remove, transfer or consolidate either any action under this
Deed of Trust or such other proceedings on such basis. The commencement or continuation of proceedings to sell the Mortgaged Property in a trustee’s sale to foreclose this Deed of Trust, or the exercise of any other rights hereunder or the
recovery of any judgment by Beneficiary in any such proceedings or the occurrence of any sale by the 

  

 15 

 
Trustee in any such proceedings shall not prejudice, limit or preclude Beneficiary’s right to commence or continue one or more trustee’s sales,
foreclosure or other proceedings or obtain a judgment against (or, in the case of a trustee’s sale, to meet the statutory requirements for, any such sale of) any other collateral (either in or outside the State in which the Premises are
located) which directly or indirectly secures the Obligations, and Grantor expressly waives any objections to the commencement of, continuation of, or entry of a judgment in such other sales or proceedings or exercise of any remedies in such sales
or proceedings based upon any action or judgment connected to this Deed of Trust, and Grantor also waives any right to seek to dismiss, stay, remove, transfer or consolidate either such other sales or proceedings or any sale or action under this
Deed of Trust on such basis. It is expressly understood and agreed that to the fullest extent permitted by law, Beneficiary may, at its election, cause the sale of all collateral that is the subject of a single foreclosure action at either a single
sale or at multiple sales conducted simultaneously and take such other measures as are appropriate in order to effect the agreement of the parties to dispose of and administer all collateral securing the Obligations (directly or indirectly) in the
most economical and least time-consuming manner. 
  

	18.	SUCCESSORS AND ASSIGNS 

 All covenants of Grantor
contained in this Deed of Trust are imposed solely and exclusively for the benefit of Beneficiary, and its successors and assigns, and no other person or entity shall have standing to require compliance with such covenants or be deemed, under any
circumstances, to be a beneficiary of such covenants, any or all of which may be freely waived in whole or in part by Beneficiary at any time if in the sole discretion of either of them such a waiver is deemed advisable. All such covenants of
Grantor shall run with the land and bind Grantor, the successors and assigns of Grantor (and each of them) and all subsequent owners, encumbrances and tenants of the Mortgaged Property, and shall inure to the benefit of Trustee and Beneficiary and
their respective successors and assigns. The word “Grantor” shall be construed as if it read “Grantors” whenever the sense of this Deed of Trust so requires and if there shall be more than one Grantor, the obligations of the
Grantors shall be joint and several. 
  

	19.	NO WAIVERS, ETC. 

 Any failure by Beneficiary to
insist upon the strict performance by Grantor of any of the terms and provisions of this Deed of Trust shall not be deemed to be a waiver of any of the terms and provisions hereof, and Beneficiary, notwithstanding any such failure, shall have the
right thereafter to insist upon the strict performance by Grantor of any and all of the terms and provisions of this Deed of Trust to be performed by Grantor. Beneficiary may release, regardless of consideration and without the necessity for any
notice to or consent by the holder of any subordinate lien on the Mortgaged Property, any part of the security held for the obligations secured by this Deed of Trust without, as to the remainder of the security, in any way impairing or affecting the
lien of this Deed of Trust or the priority of such lien over any subordinate lien or deed of trust. 
  

	20.	GOVERNING LAW, ETC. 

 This Deed of Trust shall be
governed by and construed and interpreted in accordance with the laws of the State of Texas, except that Grantor expressly acknowledges that by their respective terms the Credit Agreement and the Security Agreement shall be governed and construed in
accordance with the laws of the State of New York. 
  

 16 

	21.	DUTY OF BENEFICIARY; AUTHORITY OF BENEFICIARY 

 (a)
The Beneficiary’s sole duty with respect to the custody, safekeeping and physical preservation of the Mortgaged Property that is in its possession, or otherwise, shall be to deal with it in the same manner as the Beneficiary deals with similar
property for its own account. Neither the Beneficiary, any Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Mortgaged Property or for any
delay in doing so or shall be under any obligation to sell or otherwise dispose of any Mortgaged Property upon the request of Grantor or any other Person or to take any other action whatsoever with regard to the Mortgaged Property or any part
thereof. The powers conferred on the Beneficiary and the Secured Parties hereunder are solely to protect the Beneficiary’s and the Secured Parties’ interests in the Mortgaged Property and shall not impose any duty upon the Beneficiary or
any Secured Party to exercise any such powers. THE BENEFICIARY AND THE SECURED PARTIES SHALL BE ACCOUNTABLE ONLY FOR AMOUNTS THAT THEY ACTUALLY RECEIVE AS A RESULT OF THE EXERCISE OF SUCH POWERS, AND NEITHER THEY NOR ANY OF THEIR OFFICERS,
DIRECTORS, EMPLOYEES OR AGENTS SHALL BE RESPONSIBLE TO GRANTOR FOR ANY ACT OR FAILURE TO ACT HEREUNDER, EXCEPT FOR THEIR OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. 
 (b) Grantor acknowledges that the rights and responsibilities of the Beneficiary under this Deed of Trust with respect to any action taken by the Beneficiary or the exercise or non-exercise by the Beneficiary of any
option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Deed of Trust shall, as between the Beneficiary and the Secured Parties, be governed by the Credit Agreement and by such other
agreements with respect thereto as may exist from time to time among them, but, as between the Beneficiary and Grantor, the Beneficiary shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to
act or refrain from acting, and Grantor shall be under no obligation, or entitlement, to make any inquiry respecting such authority. 
  

	22.	LAST DOLLARS SECURED; PRIORITY 

 To the extent that
this Deed of Trust secures only a portion of the indebtedness owing or that may be owing by Grantor to the Secured Parties, the parties agree that any payments or repayments of such indebtedness shall be and be deemed to be applied first to the
portion of the indebtedness that is not secured hereby, it being the parties’ intent that the portion of the indebtedness last remaining unpaid shall be secured hereby. If at any time this Deed of Trust shall secure less than all of the
principal amount of the Obligations, it is expressly agreed that any repayments of the principal amount of the Obligations shall not reduce the amount of the lien of this Deed of Trust until the lien amount shall equal the principal amount of the
Obligations outstanding. 
  

 17 

	23.	ENFORCEMENT EXPENSES; INDEMNIFICATION 

 (a) Grantor
agrees to pay any and all reasonable and documented out-of-pocket costs and expenses (including all reasonable and documented fees, disbursements and other charges of one firm of counsel, and, if necessary, one firm of regulatory counsel and/or one
firm of local counsel in each appropriate jurisdiction, in each case to the Administrative Agent and Collateral Agent (and, in the case of an actual or perceived conflict of interest where the Person affected by such conflict informs the Borrower of
such conflict and thereafter, retains its own counsel, of another firm of counsel for such affected Person)) that may be paid or incurred by any Secured Party in enforcing, or obtaining advice of counsel in respect of, any rights with respect to, or
collecting, any or all of the Obligations and/or enforcing any rights with respect to, or collecting against, such Grantor under this Deed of Trust. 
 (b) Grantor agrees to pay, and to save the Collateral Agent and the Secured Parties harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or
other taxes which may be payable or determined to be payable with respect to any of the Mortgaged Property or in connection with any of the transactions contemplated by this Deed of Trust. 
 (c) Grantor agrees to pay, and to save the Collateral Agent and the Secured Parties harmless from, any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Deed of Trust to the extent the Borrower would be
required to do so pursuant to Section 13.5 of the Credit Agreement, AND SUBJECT TO THE PROVISO AT THE END OF SECTION 13.5 OF THE CREDIT AGREEMENT, WHETHER OR NOT CAUSED BY, OR ARISING IN WHOLE OR IN PART OUT OF, THE COMPARATIVE,
CONTRIBUTORY, OR SOLE ORDINARY NEGLIGENCE OF THE COLLATERAL AGENT OR THE SECURED PARTIES. 
 (d) The agreements in this Section 23
shall survive repayment of the Obligations and all other amounts payable under the Credit Agreement and the other Credit Documents. 
  

	24.	RELEASE 

 If any of the Mortgaged Property shall be
sold, transferred or otherwise disposed of by any Grantor in a transaction permitted by the Credit Agreement and the Net Cash Proceeds are applied in accordance with any applicable requirement (if any) of the Credit Agreement, then the Beneficiary,
at the request and sole expense of such Grantor, shall execute and deliver to such Grantor all releases or other documents reasonably necessary or desirable for the release of the Liens created hereby on such Mortgaged Property. The Grantor shall
deliver to the Beneficiary, at least five Business Days prior to the date of the proposed release, a written request for release identifying the sale or other disposition in reasonable detail, including the price thereof and any expenses in
connection therewith, together with a certification by the Grantor stating that such transaction is in compliance with, and permitted by, the Credit Agreement and the other Credit Documents. In addition, upon the execution by Grantor of an easement,
right-of-way or other real property interest that constitutes a Permitted Lien pursuant to clause (f) of the definition of Permitted Liens in the Credit Agreement (a “Permitted Real Property Interest”), Beneficiary will
subordinate the liens created hereby to the rights of third parties with respect to such Permitted Real Property Interest. 
  

 18 

	25.	SUBSTITUTE TRUSTEE 

 In case of the resignation of
the Trustee, or the inability (through death or otherwise), refusal or failure of the Trustee to act, or at the option of Beneficiary or the holder(s) of a majority of the Obligations for any other reason (which reason need not be stated), a
substitute Trustee (“Substitute Trustee”) may be named, constituted and appointed by Beneficiary or the holder(s) of a majority of the Obligations, without other formality than an appointment and designation in writing, which
appointment and designation shall be full evidence of the right and authority to make the same and of all facts therein recited, and this conveyance shall vest in the Substitute Trustee the title, powers and duties herein conferred on the Trustee
originally named herein, and the conveyance of the Substitute Trustee to the purchaser(s) at any sale of the Mortgaged Property of any part thereof shall be equally valid and effective. The right to appoint a Substitute Trustee shall exist as often
and whenever from any of said causes, the Trustee, original or Substitute Trustee, resigns or cannot, will not or does not act, or Beneficiary or the holder(s) of a majority of the Obligations desires to appoint a new Trustee. No bond shall ever be
required of the Trustee, original or Substitute Trustee. The recitals in any conveyance made by the Trustee, original or Substitute, shall be accepted and construed in court and elsewhere as prima facie evidence and proof of the facts recited, and
no other proof shall be required as to the request by Beneficiary or the holders(s) of a majority of Obligations to the Trustee to enforce this Deed of Trust, or as to the notice of or holding of the sale, or as to any particulars thereof, or as to
the resignation of the Trustee, original or Substitute, or as to the inability, refusal or failure of the Trustee, original or Substitute Trustee, to act, or as to the election of Beneficiary or the holder(s) of a majority of the Obligations to
appoint a new Trustee, or as to appointment of a Substitute Trustee, and all prerequisites of said sale shall be presumed to have been performed; and each sale made under the powers herein granted shall be a perpetual bar against Grantor and the
heirs, personal representatives, successors and assigns of Grantor. Trustee, original or substitute, is hereby authorized and empowered to appoint any one or more persons as attorney-in-fact to act as Trustee under it and in its name, place and
stead in order to take any actions that Trustee is authorized and empowered to do hereunder, such appointment to be evidenced by an instrument signed and acknowledged by said Trustee, original or Substitute Trustee; and all acts done by said
attorney-in-fact shall be valid, lawful and binding as if done by said Trustee, original or Substitute Trustee, in person. 
  

	26.	INDEMNIFICATION OF TRUSTEE 

 EXCEPT FOR GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT, TRUSTEE SHALL NOT BE LIABLE FOR ANY ACT OR OMISSION OR ERROR OF JUDGMENT. TRUSTEE MAY RELY ON ANY DOCUMENT BELIEVED BY IT IN GOOD FAITH TO BE GENUINE. ALL MONEY RECEIVED BY TRUSTEE SHALL, UNTIL USED OR APPLIED AS
HEREIN PROVIDED, BE HELD IN TRUST, AND TRUSTEE SHALL NOT BE LIABLE FOR INTEREST THEREON. GRANTOR SHALL INDEMNIFY TRUSTEE AGAINST ALL LIABILITY AND EXPENSES THAT IT MAY INCUR IN THE PERFORMANCE OF ITS DUTIES HEREUNDER EXCEPT FOR GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT. 
  

 19 

	27.	ACCEPTANCE BY TRUSTEE 

 Trustee accepts its duties
and obligations under this Deed of Trust and the Credit Documents when this Deed of Trust, duly executed and acknowledged, is made a public record as provided by law. 
  

	28.	ENTIRE AGREEMENT

	33.	ONCOR SEPARATENESS 

 (a) The Collateral Agent, on
behalf of itself and the Secured Parties, acknowledges (i) the legal separateness of the Borrower and the Grantor from the Subsidiaries of Energy Future Intermediate Holding Company LLC, a Delaware limited liability company (the
“Oncor Subsidiaries”), (ii) that the lenders under the Oncor Credit Facility and the noteholders under the Oncor Subsidiaries’ indentures have likely advanced funds thereunder in reliance upon the separateness of
the Oncor Subsidiaries from the Borrower and the Grantors, (iii) that the Oncor Subsidiaries have assets and liabilities that are separate from those of U.S. Holdings and its Subsidiaries, (iv) that the Obligations owing under the Credit
Documents are obligations and liabilities of the Borrower and the Guarantors only, and are not the obligations or liabilities of the Oncor Subsidiaries, (v) that the Secured Parties shall look solely to the Borrower, the Guarantors and their
assets, and not to any assets, or to the pledge of any assets, owned by the Oncor Subsidiaries, for the repayment of any amounts payable pursuant to the Credit Documents or any Secured Cash Management Agreement, Secured Hedging Agreement or Secured
Commodity Hedging Agreement and for satisfaction of any other Obligations owing to the Secured Parties under the Credit Documents or any Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement, and
(vi) that none of the Oncor Subsidiaries shall be personally liable to the Secured Parties for any amounts payable, or any other liability, under the Credit Documents or any Secured Cash Management Agreement, Secured Hedging Agreement or
Secured Commodity Hedging Agreement. 
 (b) The Collateral Agent, on behalf of itself and the Secured Parties, shall not (i) initiate
any legal proceeding to procure the appointment of an administrative receiver, or (ii) institute any bankruptcy, reorganization, insolvency, winding up, liquidation, or any like proceeding under applicable law, against any of the Oncor
Subsidiaries, or against any of the Oncor Subsidiaries’ assets. The Collateral Agent, on behalf of itself and the Secured Parties, acknowledges and agrees that each of the Oncor Subsidiaries is a third party beneficiary of the forgoing covenant
and shall have the right to specifically enforce such covenant in any proceeding at law or in equity. 
  

	34.	MORTGAGED LEASES 

 (a) Representations,
Warranties and Covenants. Grantor represents and warrants to Beneficiary that, with respect to each Mortgaged Lease, (i) the Mortgaged Lease is unmodified and in full force and effect, (ii) all rent and other charges therein have been
paid to the extent they are payable to the date hereof, (iii) Grantor enjoys the quiet and peaceful possession of the property demised thereby, (iv) Grantor is not in default under any of the terms thereof and there are no circumstances
which, with the passage of time or the giving of notice or both, would constitute an event of default thereunder, and (v) the lessor thereunder is not in default under any 

  

 21 

 
of the terms or provisions thereof on the part of the lessor to be observed or performed (but this statement is made for the benefit of and may only be
relied upon by Beneficiary and Secured Parties) except in the case of each of the matters described in clauses (i) through (v) of this sentence, where the failure of such statements to be true could not reasonably be expected to have a
Material Adverse Effect. Grantor shall promptly pay, when due and payable, the rent and other charges payable pursuant to the Mortgaged Lease, and will timely perform and observe all of the other terms, covenants and conditions required to be
performed and observed by Grantor as lessee under the Mortgaged Lease. Grantor shall notify Beneficiary in writing of any default by Grantor in the performance or observance of any terms, covenants or conditions on the part of Grantor to be
performed or observed under the Mortgaged Lease within ten (10) days after Grantor knows of such default. Grantor shall, promptly following the receipt thereof, deliver a copy of any notice of default given to Grantor by the lessor pursuant to
the Mortgaged Lease and promptly notify Beneficiary in writing of any default by the lessor in the performance or observance of any of the terms, covenants or conditions on the part of the lessor to be performed or observed thereunder. Unless
required under the terms of the Mortgaged Lease, except as set forth in the Credit Agreement, Grantor shall not, without the prior written consent of Beneficiary (which may be granted or withheld in Beneficiary’s sole and absolute discretion)
(A) terminate, or surrender the Mortgaged Lease, or (B) enter into any modification of the Mortgaged Lease which materially impairs the practical realization of the security interests granted by this Deed of Trust, and any such attempted
termination, modification or surrender without Beneficiary’s written consent shall be void. Grantor shall, within thirty (30) days after written request from Beneficiary, use commercially reasonable efforts to obtain from the lessor and
deliver to Beneficiary a certificate setting forth the name of the tenant thereunder and stating that the Mortgaged Lease is in full force and effect, is unmodified or, if the Mortgaged Lease has been modified, the date of each modification
(together with copies of each such modification), that no notice of termination thereof has been served on Grantor, stating that to the best of lessor’s knowledge, no default or event which with notice or lapse of time (or both) would become a
default is existing under the Mortgaged Lease, stating the date to which rent has been paid, and specifying the nature of any defaults, if any, and containing such other statements and representations as may be reasonably requested by Beneficiary.

 (b) No Merger; Acquisition; Power of Attorney. So long as any of the Obligations remain unpaid or unperformed, the fee title to and
the leasehold estate in the premises subject to each Mortgaged Lease shall not merge but shall always be kept separate and distinct notwithstanding the union of such estates in the lessor or Grantor, or in a third party, by purchase or otherwise. If
Grantor acquires the fee title or any other estate, title or interest in the property demised by the Mortgaged Lease, or any part thereof, the lien of this Deed of Trust shall attach to, cover and be a lien upon such acquired estate, title or
interest and the same shall thereupon be and become a part of the Mortgaged Property with the same force and effect as if specifically encumbered herein. Grantor agrees to execute all instruments and documents that Beneficiary may reasonably require
to ratify, confirm and further evidence the lien of this Deed of Trust on the acquired estate, title or interest. Furthermore, Grantor hereby appoints Beneficiary as its true and lawful attorney-in-fact to execute and deliver, following an Event of
Default, all such instruments and documents in the name and on behalf of Grantor. This power, being coupled with an interest, shall be irrevocable as long as any portion of the Obligations remains unpaid. 
  

 22 

 (c) New Leases. If the Mortgaged Lease shall be terminated prior to the natural expiration of its
term due to default by Grantor or any tenant thereunder, and if, pursuant to the provisions of the Mortgaged Lease, Beneficiary or its designee shall acquire from the lessor a new lease of the premises subject to the Mortgaged Lease, Grantor shall
have no right, title or interest in or to such new lease or the leasehold estate created thereby, or renewal privileges therein contained. 
 (d) No Assignment. Notwithstanding anything to the contrary contained herein, this Deed of Trust shall not constitute an assignment of any Mortgaged Lease within the meaning of any provision thereof prohibiting its assignment and
Beneficiary shall have no liability or obligation thereunder by reason of its acceptance of this Deed of Trust. Beneficiary shall be liable for the obligations of the tenant arising out of any Mortgaged Lease for only that period of time for which
Beneficiary is in possession of the premises demised thereunder or has acquired, by foreclosure or otherwise, and is holding all of Grantor’s right, title and interest therein. 
 This Deed of Trust has been duly executed by Grantor as of the date first above written and is intended to be effective as of such date.
