addition, the Collateral Trustee shall have the right at any time to exchange certificates or instruments representing or evidencing Security Collateral, if any, for certificates or instruments of smaller or larger denominations.

constitutes an “uncertificated security” (within the meaning of Article 8 of the UCC), such Pledgor will use its commercially reasonable efforts to cause the issuer thereof to agree in an authenticated record substantially in the form of

(b) above. 
 (f) At such time as any Pledgor has or acquires any Security Collateral in which such Pledgor has any right,
title or interest and that is not a security (within the meaning of Article 8 of the UCC), such Pledgor agrees that the Collateral Trustee may file a financing statement in the relevant jurisdiction. 
 (g) No Pledgor shall take or omit to take any action which would or could reasonably be expected to have the result of materially adversely
affecting or impairing the Liens in favor of the Collateral Trustee and the holders of Parity Lien Obligations with respect to the Collateral. 
 Section 5. Maintaining the Pledged Account. From and after the date on which the Pledged Account is established in accordance with the terms of each Indenture, and for so long as any

continuing.

 Section 6. Representations and Warranties. Each Pledgor represents and warrants as follows: 
 (a) Such Pledgor’s exact legal name, as defined in Section 9-503(a) of the UCC, is correctly set forth in
Schedule I hereto. Such Pledgor is located (within the meaning of Section 9-307 of the UCC) and has its chief executive office in the states or jurisdictions set forth in Schedule I hereto. The information set forth in Schedule I
hereto with respect to such Pledgor is true and accurate in all respects. Such Pledgor has not changed its name, location, chief executive office, type of organization, jurisdiction of organization or organizational identification number within the
last five years from those set forth in Schedule I hereto except as disclosed in Schedule III hereto. 
  

 7 

 (b) All Security Collateral consisting of certificated securities and
instruments has been delivered to the Collateral Trustee. 
 (c) Such Pledgor is the legal and beneficial owner
of the Collateral of such Pledgor free and clear of any Lien, claim, option or right of others, except for the security interest created under this Agreement and Liens permitted in Section 10(a)(ii)(B). No effective financing statement or other
instrument similar in effect covering all or any part of such Collateral or listing such Pledgor or any trade name of such Pledgor as debtor with respect to such Collateral is on file in any recording office, except such as may have been filed in
favor of the Collateral Trustee relating to the Secured Debt Documents or as permitted in Section 10(a)(ii)(B). 
 (d) The Initial Pledged Equity is not represented by any certificate or interest and does not constitute an “uncertificated security” as defined in Article 8 of the UCC and as used in Article 9 of the UCC. 
 (e) The Pledged Equity pledged by such Pledgor hereunder has been duly authorized and validly issued and is fully paid and
non-assessable. With respect to any Pledged Equity that is an “uncertificated security” (within the meaning of Article 8 of the UCC), such Pledgor has used its commercially reasonable efforts to cause the issuer thereof to agree in an
authenticated record with such Pledgor and the Collateral Trustee that such issuer will comply with instructions with respect to such security originated by the Collateral Trustee without further consent of such Pledgor. If such Pledgor is an issuer
of Pledged Equity, such Pledgor confirms that it has received notice of such security interest. The Pledged Debt pledged by such Pledgor hereunder has been duly authorized, authenticated or issued and delivered, is the legal, valid and binding
obligation of the issuers thereof, is evidenced by one or more promissory notes (which notes have been delivered to the Collateral Trustee) and is not in default. 
 (f) The Initial Pledged Equity pledged by the Initial Pledgor (i) constitutes the percentage of the issued and
outstanding Equity Interests of the issuer thereof indicated on Schedule II hereto and (ii) represents all Equity Interests directly held by the Initial Pledgor in any Oncor Subsidiary. As of the date hereof, there is no outstanding
indebtedness owed to the Initial Pledgor by any Oncor Subsidiary. The Initial Pledgor has no Investments in any Oncor Subsidiary. 
 (g) All filings and other actions (including without limitation, actions necessary to obtain control of Collateral as provided in Section 9-106 of the UCC)

  

 8 

 
necessary to perfect the security interest in the Collateral of such Pledgor created under this Agreement have been duly made or taken and are in full force and effect, and this Agreement creates
in favor of the Collateral Trustee for the benefit of the holders of Parity Lien Obligations a valid and, together with such filings and other actions, perfected first priority security interest in the Collateral of such Pledgor, securing the
payment of the Secured Obligations, subject to Liens permitted in Section 10(a)(ii)(B). 
 (h) No
authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body or any other third party is required for (i) the grant by such Pledgor of the security interest granted hereunder or
for the execution, delivery or performance of this Agreement by such Pledgor, (ii) the perfection or maintenance of the security interest created hereunder (including the first priority nature of such security interest), except for the filing
of financing and continuation statements under the UCC, which financing statements have been duly filed and are in full force and effect, and the actions described in Section 4 with respect to Security Collateral, which actions have been taken
and are in full force and effect or (iii) the exercise by the Collateral Trustee of its voting or other rights provided for in this Agreement or the remedies in respect of the Collateral pursuant to this Agreement, except (A) as may be
required in connection with the disposition of any portion of the Security Collateral by laws affecting the offering and sale of securities generally and (B) with respect to clause (iii) above, the limitations set forth in Section 3.3
of the Collateral Trust Agreement. 
 Section 7. Further Assurances. (a) Each Pledgor agrees that from time to
time, at the expense of such Pledgor, such Pledgor will promptly execute and deliver, or otherwise authenticate, all further instruments and documents, and take all further action that may be necessary or desirable, or that the Collateral Trustee
may reasonably request, in order to perfect and protect any pledge or security interest granted or purported to be granted by such Pledgor hereunder or to enable the Collateral Trustee to exercise and enforce its rights and remedies hereunder with
respect to any Collateral of such Pledgor. Without limiting the generality of the foregoing, each Pledgor will promptly with respect to Collateral of such Pledgor: (i) if any such Collateral shall be evidenced by a promissory note or other
instrument in an aggregate principal amount of one million dollars ($1,000,000) or greater, deliver and pledge to the Collateral Trustee hereunder such note or instrument duly indorsed and accompanied by duly executed instruments of transfer or
assignment, all in form and substance reasonably satisfactory to the Collateral Trustee; (ii) file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as
the Collateral Trustee may reasonably request, in order to perfect and preserve the security interest granted or purported to be granted by such Pledgor hereunder; (iii) deliver and pledge to the Collateral Trustee for benefit of the holders of
Parity Lien Obligations certificates representing Security Collateral that constitutes certificated securities, accompanied by undated stock or bond powers executed in blank; (iv) take all action necessary to ensure that the Collateral Trustee
has control of Collateral consisting of investment property as provided in Section 9-106 of the UCC; and (v) deliver to the Collateral Trustee evidence that all other action that the Collateral Trustee may deem reasonably necessary or
desirable in order to perfect and protect the security interest created by such Pledgor under this Agreement has been taken. 
  

 9 

 (b) Each Pledgor hereby authorizes the Collateral Trustee to file one or more financing or
continuation statements, and amendments thereto, including, without limitation, one or more financing statements indicating that such financing statements cover the Collateral described herein, in each case without the signature of such Pledgor.

 Section 8. Post-Closing Changes. Neither the Initial Pledgor nor any Additional Pledgor will, following the date
on which it becomes bound by this Agreement, change its name, type of organization, jurisdiction of organization, organizational identification number or location from those set forth in Section 6(a) without first giving at least 15 days’
prior written notice to the Collateral Trustee and taking all action required by the Collateral Trustee for the purpose of perfecting or protecting the security interest granted by this Agreement. Each Pledgor will hold and preserve its records
relating to the Collateral and will permit representatives of the Collateral Trustee at any time during normal business hours to inspect and make abstracts from such records and other documents. If any Pledgor does not have an organizational
identification number on the day it becomes bound by this Agreement and later obtains one, it will forthwith notify the Collateral Trustee of such organizational identification number. 
 Section 9. Voting Rights; Dividends; Etc. (a) So long as no Event of Default and no event of default under any other Parity Lien
Debt shall have occurred and be continuing: 
 (i) Each Pledgor shall be entitled to exercise any and all voting
and other consensual rights pertaining to the Security Collateral of such Pledgor or any part thereof for any purpose not inconsistent with the terms of this Agreement or the Secured Debt Documents. 
 (ii) Each Pledgor shall be entitled to receive and retain any and all dividends, interest and other distributions paid in
respect of the Security Collateral of such Pledgor if and to the extent that the payment thereof is not otherwise prohibited by the terms of the Secured Debt Documents; provided, however, that any and all dividends, interest and other
distributions paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Security Collateral, shall be, and shall be forthwith delivered
to the Collateral Trustee to hold as, Security Collateral and shall, if received by such Pledgor, be received in trust for the benefit of the Collateral Trustee, be segregated from the other property or funds of such Pledgor and be forthwith
delivered to the Collateral Trustee as Security Collateral in the same form as so received (with any necessary indorsement). 
 (iii) The Collateral Trustee will execute and deliver (or cause to be executed and delivered) to each Pledgor all such proxies and other instruments as such Pledgor may reasonably request for the purpose
of enabling such Pledgor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above and to receive the dividends or interest payments that it is authorized to receive and retain pursuant to
paragraph (ii) above. 
 (b) Upon the occurrence and during the continuance of an Event of Default or an event of default
under any other Parity Lien Debt: 
 (i) All rights of each Pledgor (x) to exercise or refrain from
exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 9(a)(i) shall, upon notice to such Pledgor by the Collateral Trustee, cease and (y) to receive the dividends, interest
and other distributions that it would otherwise be authorized to receive and retain pursuant to Section 9(a)(ii) shall automatically cease, and all such rights shall thereupon become vested in the Collateral Trustee, which shall thereupon have
the sole right to exercise or refrain from exercising such voting and other consensual rights and to receive and hold as Security Collateral such dividends, interest and other distributions. 
  

 10 

 (ii) All dividends, interest and other distributions that are received by
any Pledgor contrary to the provisions of paragraph (i) of this Section 9(b) shall be received in trust for the benefit of the Collateral Trustee, shall be segregated from other funds of such Pledgor and shall be forthwith paid over to the
Collateral Trustee as Security Collateral in the same form as so received (with any necessary indorsement). 
 Section 10.
Transfers and Other Liens; Additional Shares. (a) Each Pledgor agrees that it will not (i) sell, assign or otherwise dispose of, or grant any option with respect to, any of the Collateral, other than sales, assignments and other
dispositions of Collateral, and options relating to Collateral, permitted under the terms of the Indentures and documents governing other Parity Lien Debt, or (ii) create or suffer to exist any Lien upon or with respect to any of the Collateral
of such Pledgor except for (A) the pledge, assignment and security interest created under this Agreement and (B) Liens permitted under Section 4.12(b) of each of the Indentures. 
 (b) EFIH agrees that it will pledge hereunder, promptly upon its receipt thereof (but in no event later than five Business Days after such
receipt), any and all additional Equity Interests or other securities of any Oncor Subsidiary. 
 (c) Each Pledgor agrees that
it will not enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness of any Person other than as permitted by the Indentures, the
Notes and the Collateral Trust Agreement. 
 Section 11. Collateral Trustee Appointed Attorney-in-Fact. Each Pledgor
hereby irrevocably appoints the Collateral Trustee such Pledgor’s attorney-in-fact, with full authority in the place and stead of such Pledgor and in the name of such Pledgor or otherwise, from time upon the occurrence and during the
continuance of an Event of Default in the Collateral Trustee’s discretion, to take any action and to execute any instrument that the Collateral Trustee may deem necessary or advisable to accomplish the purposes of this Agreement, including,
without limitation: 
 (a) to ask for, demand, collect, sue for, recover, compromise, receive and give
acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral, 
  

 11 

 (b) to receive, indorse and collect any drafts or other instruments or
documents, in connection with clause (a) above, and 
 (c) to file any claims or take any action or
institute any proceedings that the Collateral Trustee may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Collateral Trustee with respect to any of the Collateral. 
 Section 12. Collateral Trustee May Perform. If any Pledgor fails to perform any agreement contained herein, the Collateral
Trustee may, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the expenses of the Collateral Trustee incurred in connection therewith shall be payable by such Pledgor under
Section 15. 
 Section 13. The Collateral Trustee’s Duties. (a) The powers conferred on the
Collateral Trustee hereunder are solely to protect the holders of Parity Lien Obligations’ interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its
possession and the accounting for moneys actually received by it hereunder, the Collateral Trustee shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or
other matters relative to any Collateral, whether or not any holder of Parity Lien Obligations has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights
pertaining to any Collateral. The Collateral Trustee 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 it
accords its own property. 
 (b) Anything contained herein to the contrary notwithstanding, the Collateral Trustee may from time
to time, when the Collateral Trustee deems it to be necessary, appoint one or more subagents (each a “Subagent”) for the Collateral Trustee hereunder with respect to all or any part of the Collateral. In the event that the
Collateral Trustee so appoints any Subagent with respect to any Collateral, (i) the assignment and pledge of such Collateral and the security interest granted in such Collateral by each Pledgor hereunder shall be deemed for purposes of this
Agreement to have been made to such Subagent, in addition to the Collateral Trustee, for the ratable benefit of the holders of Parity Lien Obligations, as security for the Secured Obligations of such Pledgor, (ii) such Subagent shall
automatically be vested, in addition to the Collateral Trustee, with all rights, powers, privileges, interests and remedies of the Collateral Trustee hereunder with respect to such Collateral, and (iii) the term “Collateral Trustee,”
when used herein in relation to any rights, powers, privileges, interests and remedies of the Collateral Trustee with respect to such Collateral, shall include such Subagent; provided, however, that no such Subagent shall be authorized
to take any action with respect to any such Collateral unless and except to the extent expressly authorized in writing by the Collateral Trustee.

 Section 14. Remedies. If any Event of Default shall have occurred and be
continuing: 
 (a) Subject to Section 3.3(b) and Section 3.3(c) of the Collateral Trust Agreement, the
Collateral Trustee may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a holder of Parity Lien Obligations upon default under the UCC
(whether or not the UCC applies to the affected Collateral) and also may: (i) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral
Trustee’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Collateral Trustee may deem commercially reasonable; and (ii) exercise any and all rights and remedies of any of the Pledgors
under or in connection with the Collateral, or otherwise in respect of the Collateral, including, without limitation, those set forth in Section 9-607 of the UCC. Each Pledgor agrees that, to the extent notice of sale shall be required by law,
at least 10 days’ notice to such Pledgor 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 Trustee shall not be obligated to make any sale of
Collateral regardless of notice of sale having been given. The Collateral Trustee 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. 
 (b) Any cash held by or on behalf of the Collateral Trustee
and all cash proceeds received by or on behalf of the Collateral Trustee in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Collateral Trustee, be held by the
Collateral Trustee as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Collateral Trustee pursuant to Section 15) in whole or in part by the Collateral Trustee for the ratable benefit of
the holders of Parity Lien Obligations against, all or any part of the Secured Obligations, in the manner set forth in Section 3.4 of the Collateral Trust Agreement. 
 (c) All payments received by any Pledgor in respect of the Collateral shall be received in trust for the benefit of the
Collateral Trustee, shall be segregated from other funds of such Pledgor and shall be forthwith paid over to the Collateral Trustee in the same form as so received (with any necessary indorsement). 
 (d) The Collateral Trustee is authorized, in connection with any sale of the Security Collateral pursuant to this
Section 14, to deliver or otherwise disclose to any prospective purchaser of the Security Collateral any information in its possession relating to such Security Collateral. 
 Section 15. Indemnity and Expenses. (a) Each Pledgor agrees to indemnify, defend and save and hold harmless the Collateral
Trustee and each of its officers, directors, employees, agents and advisors (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including,
without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or resulting from this Agreement (including, without
limitation, enforcement of this Agreement),

  

 13 

 
except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from an Indemnified
Party’s gross negligence or willful misconduct. 
 (b) Each Pledgor will upon demand pay to the Collateral Trustee the
amount of any and all expenses documented in customary detail, including, without limitation, the fees and expenses of its counsel and of any experts and agents documented in customary detail, that the Collateral Trustee may incur in connection with
(i) the administration of this Agreement, (ii) the custody or preservation of, or the sale of, collection from or other realization upon, any of the Collateral of such Pledgor, (iii) the exercise or enforcement of any of the rights of
the Collateral Trustee or the other holders of Parity Lien Obligations hereunder or (iv) the failure by such Pledgor to perform or observe any of the provisions hereof. 
 Section 16. Amendments; Waivers; Additional Pledgors; Etc. (a) No amendment or waiver of any provision of this Agreement, and no
consent to any departure by any Pledgor herefrom, shall in any event be effective unless the same shall be in writing and signed by the Collateral Trustee, and then such waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given. No failure on the part of the Collateral Trustee or any other holder of Parity Lien Obligations to exercise, and no delay in exercising any right hereunder, shall operate as a waiver thereof; nor shall any single or
partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. 
 (b)
Upon the execution and delivery, or authentication, by any Person of a pledge agreement supplement in substantially the form of Exhibit A hereto (each a “Pledge Agreement Supplement”), (i) such Person shall be referred
to as an “Additional Pledgor” and shall be and become a Pledgor hereunder, and each reference in this Agreement and the other Secured Debt Documents to “Pledgor” shall also mean and be a reference to such Additional
Pledgor, and each reference in this Agreement and the other Secured Debt Documents to “Collateral” shall also mean and be a reference to the Collateral of such Additional Pledgor, and (ii) the supplemental schedules I-III attached to
each Pledge Agreement Supplement shall be incorporated into and become a part of and supplement Schedules I-III, respectively, hereto, and the Collateral Trustee may attach such supplemental schedules to such Schedules; and each reference to such
Schedules shall mean and be a reference to such Schedules as supplemented pursuant to each Pledge Agreement Supplement. 
 Section 17. Notices, Etc. All notices and other communications provided for hereunder shall be either (i) in writing (including telegraphic, telecopier or telex communication) and mailed, telegraphed, telecopied, telexed or
otherwise delivered or (ii) by electronic mail (if electronic mail addresses are designated as provided below) confirmed immediately in writing, in the case of the Initial Pledgor or the Collateral Trustee, addressed to it at its address
specified in the Collateral Trust Agreement and, in the case of each Pledgor other than the Initial Pledgor, addressed to it at its address set forth on the signature page to the Pledge Agreement Supplement pursuant to which it became a party

or otherwise, be effective when deposited in the mails, delivered to the telegraph company, telecopied, confirmed by telex answerback, sent by electronic mail and confirmed in writing, or

  

 14 

 
otherwise delivered (or confirmed by a signed receipt), respectively, addressed as aforesaid; except that notices and other communications to the Collateral Trustee shall not be effective until
received by the Collateral Trustee. Delivery by telecopier of an executed counterpart of any amendment or waiver of any provision of this Agreement or of any Pledge Agreement Supplement or Schedule hereto shall be effective as delivery of an
original executed counterpart thereof. 
 Section 18. Continuing Security Interest. This Agreement shall create a
continuing security interest in the Collateral and shall (a) remain in full force and effect until the latest of (i) the payment in full in cash of the Secured Obligations and (ii) October 15, 2019, (b) be binding upon each
Pledgor, its successors and assigns and (c) inure, together with the rights and remedies of the Collateral Trustee hereunder, to the benefit of the holders of Parity Lien Obligations and their respective successors, transferees and assigns.

 Section 19. Release; Termination. (a) Upon any sale, transfer or other disposition of any item of Collateral
of any Pledgor in accordance with the terms of the Secured Debt Documents, the Collateral Trustee will, at such Pledgor’s expense, execute and deliver to such Pledgor such documents as such Pledgor shall reasonably request to evidence the
release of such item of Collateral from the security interest granted hereby in accordance with provisions of Section 3.2 and Section 4.1 of the Collateral Trust Agreement. 
 (b) Upon the payment in full in cash of the Secured Obligations, the pledge and security interest granted hereby shall terminate and all
rights to the Collateral shall revert to the applicable Pledgor. Upon any such termination, the Collateral Agent will, at the applicable Pledgor’s expense, execute and deliver to such Pledgor such documents as such Pledgor shall reasonably
request to evidence such termination. 
 Section 20. Security Interest Absolute. The obligations of each Pledgor
under this Agreement are independent of the Secured Obligations or any other Obligations of any other Pledgor under or in respect of the Parity Lien Documents, and a separate action or actions may be brought and prosecuted against each Pledgor to
enforce this Agreement, irrespective of whether any action is brought against such Issuer or Pledgor or whether such Issuer or Pledgor is joined in any such action or actions. All rights of the Collateral Agent and the other Secured Parties and the
pledge, assignment and security interest hereunder, and all obligations of each Pledgor hereunder, shall be irrevocable, absolute and unconditional irrespective of, and each Pledgor hereby irrevocably waives (to the maximum extent permitted by
applicable law) any defenses it may now have or may hereafter acquire in any way relating to, any or all of the following: 
 (a) any lack of validity or enforceability of any Parity Lien Document or any other agreement or instrument relating thereto; 
 (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Secured Obligations or
any other Obligations of any Issuer under or in respect of the Parity Lien Document or any other amendment or waiver of or any consent to any departure from any Parity Lien Document, including, without limitation, any increase in the Secured
Obligations resulting from the extension of additional credit to any Issuer or any of its Subsidiaries or otherwise; 
  

 15 

 (c) any taking, exchange, release or non-perfection of any Collateral or any
other collateral, or any taking, release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Secured Obligations; 
 (d) any manner of application of any Collateral or any other collateral, or proceeds thereof, to all or any of the Secured Obligations, or any manner of sale or other disposition of any Collateral or any
other collateral for all or any of the Secured Obligations or any other Obligations of any Issuer under or in respect of the Parity Lien Documents or any other assets of any Issuer or any of its Subsidiaries; 
 (e) any change, restructuring or termination of the corporate structure or existence of any Issuer or any of its
Subsidiaries; 
 (f) any failure of any Secured Party to disclose to any Pledgor any information relating to the
business, condition (financial or otherwise), operations, performance, assets, nature of assets, liabilities or prospects of any Issuer or Pledgor now or hereafter known to such Secured Party (each Pledgor waiving any duty on the part of the Secured
Parties to disclose such information); 
 (g) the failure of any other Person to execute this Agreement or any
other Collateral Document, guaranty or agreement or the release or reduction of liability of any Pledgor or other grantor or surety with respect to the Secured Obligations; or 
 (h) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any
representation by any Secured Party that might otherwise constitute a defense available to, or a discharge of, such Pledgor or any other Pledgor or a third party grantor of a security interest. 
 This Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Secured Obligations is
rescinded or must otherwise be returned by any Secured Party or by any other Person upon the insolvency, bankruptcy or reorganization of any Issuer or otherwise, all as though such payment had not been made. 
 Section 21. Execution in Counterparts. This Agreement may be executed in any number of counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of an
original executed counterpart of this Agreement. 
 Section 22. Limitation of Liability. (a) In no event shall
the Collateral Trustee be responsible or liable for any failure or delay in the performance of its obligations under this Agreement arising out of or caused by, directly or indirectly, forces beyond its reasonable control, including without
limitation strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software or
hardware) services. 
  

 16 

 (b) In no event shall the Collateral Trustee be responsible or liable for special, indirect,
or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Collateral Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

 Section 23. Governing Law. (a) This Agreement shall be governed by, and construed in accordance with, the
laws of the State of New York. 
 (b) Each Pledgor hereby irrevocably and unconditionally submits, for itself and its property,
to the nonexclusive jurisdiction of any New York State court or federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this
Agreement or any of the other Parity Lien Documents to which it is or is to be a party, or for recognition or enforcement of any judgment, and each Pledgor hereby irrevocably and unconditionally agrees that all claims in respect of any such action
or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court. Each Pledgor agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced
in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Parity Lien Document shall affect any right that any party may otherwise have to bring any action or proceeding relating to
this Agreement or any other Parity Lien Document in the courts of any jurisdiction. 
 (c) Each Pledgor irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any of the
other Parity Lien Documents to which it is or is to be a party in any New York State or federal court. Each Pledgor hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such
suit, action or proceeding in any such court. 
 (d) EACH PLEDGOR HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OF THE PARITY LIEN DOCUMENTS, OR ANY OF THE TRANSACTIONS
CONTEMPLATED THEREBY.

            (“            ”), as issuer (the “Issuer”). 
 PRELIMINARY STATEMENTS: 
 (1) The
Grantor has granted the Secured Party a security interest (the “Security Interest”) in [identify uncertificated security] issued by the Issuer to the Grantor (the “Uncertificated Security”).

 (2) Terms defined in Article 8 or 9 of the Uniform Commercial Code in effect in the State of New York (the “N.Y.
Uniform Commercial Code”) are used in this Agreement as such terms are defined in such Article 8 or 9. 
 NOW,
THEREFORE, in consideration of the premises and of the mutual agreements contained herein, the parties hereto hereby agree as follows: 
 Section 1. The Uncertificated Security. The Grantor and the Issuer represent and warrant to, and agree with, the Secured Party that: 
 (a) The Uncertificated Security is an uncertificated security. The Issuer is the issuer of the Uncertificated Security. The Grantor is the registered owner of the Uncertificated Security. 
 (b) The State of [            ] is, and will continue to be,
the Issuer’s jurisdiction for purposes of Section 8-110(d) of the [            ] Uniform Commercial Code so long as the Security Interest shall remain in effect.1 
 (c) The Grantor and the Issuer do not know of any claim to or interest in the Uncertificated Security, except for claims and interests of the parties referred to in this Agreement. 
 Section 2. Control by Secured Party. The Issuer will comply with all notifications it receives directing it to transfer the
Uncertificated Security (each an “Entitlement Order”) or other directions concerning the Uncertificated Security (including, without limitation, 
  

	1	If the UCC or equivalent laws in the Issuer’s jurisdiction allow such Issuer to specify its jurisdiction to be New York, then such specification should be made
here; provided that the Issuer shall not be required to take any action not contemplated by this Agreement or the Collateral Trust Agreement in connection with such specification. 

 
directions to distribute to the Secured Party proceeds of any such transfer or interest or dividends on the Uncertificated Security) originated by the Secured Party without further consent by the
Grantor. 
 Section 3. Grantor’s Rights in Uncertificated Security. (a) Until the Issuer receives a notice
from the Secured Party that the Secured Party will exercise exclusive control over the Uncertificated Security (a “Notice of Exclusive Control”), the Issuer may comply with Entitlement Orders or other directions concerning
the Uncertificated Security originated by the Grantor and may distribute to the Grantor all interest and regular cash dividends on the Uncertificated Security. 
 (b) If the Issuer receives from the Secured Party a Notice of Exclusive Control, the Issuer will cease distributing to the
Grantor all interest and dividends on the Uncertificated Security. 
 Section 4. Statements, Confirmations and Notices
of Adverse Claims. (a) The Issuer will send copies of all notices and other communications with respect to the Uncertificated Security simultaneously to the Grantor and the Secured Party. 
 (b) When the Issuer knows of any claim or interest in the Uncertificated Security other than the claims and interests of the
parties referred to in this Agreement, the Issuer will promptly notify the Secured Party and the Grantor of such claim or interest. 
 Section 5. The Issuer’s Responsibility. (a) The Issuer will not be liable to the Grantor or the Secured Party for complying with a Notice of Exclusive Control or with an Entitlement Order or other direction concerning
the Uncertificated Security originated by the Secured Party, even if the Grantor notifies the Issuer that the Secured Party is not legally entitled to issue the Notice of Exclusive Control or Entitlement Order or such other direction unless the
Issuer takes the action after it is served with an injunction, restraining order or other legal process enjoining it from doing so, issued by a court of competent jurisdiction, and had a reasonable opportunity to act on the injunction, restraining
order or other legal process. 
 (b) This Agreement does not create any obligation of the Issuer except for those
expressly set forth in this Agreement and in Part 5 of Article 8 of the N.Y. Uniform Commercial Code. In particular, the Issuer need not investigate whether the Secured Party is entitled under the Secured Party’s agreements with the Grantor to
give an Entitlement Order or other direction concerning the Uncertificated Security or a Notice of Exclusive Control. The Issuer may rely on notices and communications it believes given by the appropriate party. 
 Section 6. Indemnity. The Grantor will indemnify the Issuer, its officers, directors, employees and agents against claims,
liabilities and expenses arising out of this Agreement (including, without limitation, reasonable attorney’s fees and disbursements), except to the extent the claims, liabilities or expenses are caused by the Issuer’s gross negligence or
willful misconduct as found by a court of competent jurisdiction in a final, non-appealable judgment.

Obligations nor any Junior Lien Representative may file or prosecute in any Insolvency or Liquidation Proceeding any motion for adequate protection (or any comparable request for relief) based upon their interest in the Collateral under the Junior
Liens, except that: 
 (1) they may freely seek and obtain relief granting a Junior Lien co-extensive in all
respects with, but subordinated (as set forth in Section 2.3) to, all Liens granted in such Insolvency or Liquidation Proceeding to, or for the benefit of, the holders of Parity Lien Obligations; and 
  

 22 

 (2) they may freely seek and obtain any relief upon a motion for adequate
protection (or any comparable relief), without any condition or restriction whatsoever, at any time after the Discharge of Parity Lien Obligations. 
 SECTION 2.9 Collateral Shared Equally and Ratably within Class. The parties to this Agreement agree that the payment and satisfaction of all of the Parity Lien Obligations and Junior Lien
Obligations will be secured Equally and Ratably by the Liens established in favor of the Collateral Trustee for the benefit of the Secured Parties belonging to such Class. It is understood and agreed that nothing in this Section 2.9 is intended
to alter the priorities among Secured Parties belonging to different Classes as provided in Section 2.3. 
 ARTICLE 3.
OBLIGATIONS AND POWERS OF COLLATERAL TRUSTEE 
 SECTION 3.1 Undertaking of the Collateral Trustee. 
 (a) Subject to, and in accordance with, this Agreement, including without limitation Section 5.3, the Collateral Trustee will, as
collateral trustee, for the benefit solely and exclusively of the current and future Secured Parties: 
 (1)
accept, enter into, hold, maintain, administer and enforce all Security Documents, including all Collateral subject thereto, and all Liens created thereunder, perform its obligations under the Security Documents and protect, exercise and enforce the
interests, rights, powers and remedies granted or available to it under, pursuant to or in connection with the Security Documents; 
 (2) take all lawful and commercially reasonable actions permitted under the Security Documents that it may deem necessary to protect or preserve its interest in the Collateral subject thereto and such
interests, rights, powers and remedies; 
 (3) deliver and receive notices pursuant to the Security Documents;

 (4) sell, assign, collect, assemble, foreclose on, institute legal proceedings with respect to, or otherwise
exercise or enforce the rights and remedies of a secured party (including a mortgagee, trust deed beneficiary and insurance beneficiary or loss payee) with respect to the Collateral under the Security Documents and its other interests, rights,
powers and remedies; 
 (5) remit as provided in Section 3.4 all cash proceeds received by the Collateral
Trustee from the collection, foreclosure or enforcement of its interest in the Collateral under the Security Documents or any of its other interests, rights, powers or remedies; 
  

 23 

 (6) execute and deliver amendments to the Security Documents as from time to
time authorized pursuant to Section 7.1 accompanied by an Officer’s Certificate to the effect that the amendment was permitted under Section 7.1; and 
 (7) release any Lien granted to it by any Security Document upon any Collateral if and as required by Section 4.1.

 (b) Each party to this Agreement acknowledges and consents to the undertaking of the Collateral Trustee set forth in
Section 3.1(a) and agrees to each of the other provisions of this Agreement applicable to the Collateral Trustee. 
 (c)
Notwithstanding anything to the contrary contained in this Agreement, the Collateral Trustee will not commence any exercise of remedies or any foreclosure actions or otherwise take any action or proceeding against any of the Collateral (other than
actions as necessary to prove, protect or preserve (but not enforce) the Liens securing the Secured Debt Obligations, subject to Section 5.9 of this Agreement) unless and until it shall have been directed by an Act of Required Debtholders, and
then only in accordance with the provisions of this Agreement. 
 (d) The Collateral Trustee shall be under no obligation to
exercise any of its rights or powers under this Agreement or any Security Document at the request or direction of any holder of Secured Debt unless such holders of Secured Debt shall have offered to the Collateral Trustee indemnity or security
reasonably satisfactory to it against any loss, liability or expense. 
 SECTION 3.2 Release or Subordination of Liens.
The Collateral Trustee will not release or subordinate any Lien of the Collateral Trustee or consent to the release or subordination of any Lien of the Collateral Trustee, except: 
 (a) as directed by an Act of Required Debtholders accompanied by an Officer’s Certificate to the effect that the release or
subordination was permitted by each applicable Secured Debt Document; 
 (b) as required by Article 4; 
 (c) as ordered pursuant to applicable law under a final and nonappealable order or judgment of a court of competent jurisdiction; or

 (d) for the subordination of the Junior Trust Estate and the Junior Liens to the Senior Trust Estate and the Parity Liens.

 SECTION 3.3 Enforcement of Liens. 
 (a) If the Collateral Trustee at any time receives written notice stating that any event has occurred that constitutes a default under any Secured Debt Document entitling the Collateral Trustee to
foreclose upon, collect or otherwise enforce its Liens thereunder, the Collateral Trustee will promptly deliver written notice thereof to each Secured Debt Representative. Thereafter, the Collateral Trustee will await direction by an Act of Required

  

 24 

 
Debtholders and will act, or decline to act, as directed by an Act of Required Debtholders, in the exercise and enforcement of the Collateral Trustee’s interests, rights, powers and remedies
in respect of the Collateral or under the Security Documents or applicable law and, following the initiation of such exercise of remedies, the Collateral Trustee will act, or decline to act, with respect to the manner of such exercise of remedies as
directed by an Act of Required Debtholders. Unless it has been directed to the contrary by an Act of Required Debtholders, the Collateral Trustee in any event may (but will not be obligated to) take or refrain from taking such action with respect to
any default under any Secured Debt Document as it may deem advisable to preserve and protect the value of the Collateral. 
 (b)
Regulatory approvals may be required in order to enforce the security interests against the Collateral and to dispose of an interest in, or operational control of, the Collateral that secures the EFIH Notes and EFIH’s guarantee of the EFH
Notes. 
 The Collateral securing the EFIH Notes and EFIH’s guarantee of the EFH Notes will include all of the membership
interests of Oncor Electric Delivery Holdings Company LLC (“Oncor Holdings”), which are held by EFIH. Pursuant to the Public Utility Regulatory Act (“PURA”), Texas Utilities Code §§39.262(l)
and 39.915, an electric utility must obtain prior approval of the Public Utility Commission of Texas (“PUCT”) of any change in majority ownership, controlling ownership or operational control of Oncor Electric Delivery
Company LLC (“Oncor”). As a result, prior to any foreclosure on the membership interests of Oncor Holdings, approval of the PUCT may be required for a change in ownership or control of Oncor Holdings. Pursuant to PURA
§§39.262(m) and 39.915(b), the PUCT will approve such a transfer if it finds that the transaction is in the public interest. In making its determination, these sections of PURA provide that the PUCT will consider whether the transaction
will adversely affect the reliability of service, availability of service or cost of service of Oncor. Therefore, in connection with any action taken to enforce the security against the Collateral, such approval may not be granted and, if it were to
be granted, it is not known how long such approval would take to obtain. Even if the approval were granted to foreclose on the Collateral, then additional prior PUCT approval may also be required for any subsequent change in majority ownership,
controlling ownership or operational control in the membership interests of Oncor Holdings. 
 (c) In addition, pursuant to the
terms of an investor rights agreement, among EFH, Oncor Holdings, Oncor and Texas Transmission Investment LLC (“Texas Transmission”), the noncontrolling investor in Oncor, any transfer of the equity interests in Oncor
Holdings to a third party, including as a result of any enforcement of the lien on the Collateral securing the EFIH Notes and EFIH’s guarantee of the EFH Notes, may be limited and give rise to a tag-along right of Texas Transmission to
participate in that transfer on a pro rata basis, which may hinder the enforcement of the lien on the Collateral in a timely manner, if at all. 
 SECTION 3.4 Application of Proceeds. 
 (a) If any Collateral is sold or
otherwise realized upon by the Collateral Trustee in connection with any foreclosure, collection or other enforcement of Parity Liens or Junior Liens granted to the Collateral Trustee in the Security Documents, the proceeds received by the
Collateral Trustee from such foreclosure, collection or other enforcement will be distributed by the Collateral Trustee in the following order of application: 
 FIRST, to the payment of all amounts payable under this Agreement on account of the Collateral Trustee’s fees and any
reasonable legal fees, costs and expenses or other liabilities of any kind incurred by the Collateral Trustee or any co-trustee or agent of the Collateral Trustee in connection with any Security Document; 
  

 25 

 SECOND, ratably to the respective Parity Lien Representatives for
application, after payment of any fees and expenses (including but not limited to, attorney’s fees and expenses) of such Parity Lien Representative, to the payment of all outstanding Notes and other Parity Lien Debt and any other Parity Lien
Obligations that are then due and payable in such order as may be provided in the relevant Parity Lien Documents in an amount sufficient to pay in full in cash all outstanding Notes and other Parity Lien Debt and all other Parity Lien Obligations
that are then due and payable (including all interest accrued thereon after the commencement of any Insolvency or Liquidation Proceeding at the rate, including any applicable post-default rate, specified in the relevant Parity Lien Documents, even
if such interest is not enforceable, allowable or allowed as a claim in such proceeding, and including the discharge or cash collateralization (at the lower of (1) 105% of the aggregate undrawn amount and (2) the percentage of the
aggregate undrawn amount required for release of Liens under the terms of the applicable Parity Lien Document) of all outstanding letters of credit constituting Parity Lien Debt); 
 THIRD, to the respective Junior Lien Representatives for application to the payment of all outstanding Junior Lien Debt and
any other Junior Lien Obligations that are due and payable in such order as may be provided in the Junior Lien Documents in an amount sufficient to pay in full in cash all outstanding Junior Lien Debt and all other Junior Lien Obligations that are
then due and payable (including all interest accrued thereon after the commencement of any Insolvency or Liquidation Proceeding at the rate, including any applicable post-default rate, specified in the Junior Lien Documents, even if such interest is
not enforceable, allowable or allowed as a claim in such proceeding, and including the discharge or cash collateralization (at the lower of (1) 105% of the aggregate undrawn amount and (2) the percentage of the aggregate undrawn amount
required for release of Liens under the terms of the applicable Junior Lien Document) of all outstanding letters of credit, if any, constituting Junior Lien Debt); and 
 FOURTH, any surplus remaining after the payment in full in cash of the amounts described in the preceding clauses will be
paid to EFIH, or its successors or assigns, or as a court of competent jurisdiction may direct. 
 If any Junior
Lien Representative or any holder of a Junior Lien Obligation collects or receives any proceeds in respect of any foreclosure, collection or other enforcement to which it was not entitled pursuant to the terms of the immediately preceding
paragraphs, whether after the commencement of any Insolvency or Liquidation Proceeding or otherwise, such Junior Lien Representative or such holder of a Junior Lien Obligation, as the case may be, will forthwith deliver the same to the Collateral
Trustee to be applied in accordance with the provisions set forth in the immediately preceding paragraphs. Until so delivered, such proceeds will be held by that Junior Lien Representative or that holder of a Junior Lien Obligation, as the case may
be, in trust for the benefit of the holders of the Parity Lien Obligations. These provisions will not apply to payments received by any holder of Junior Lien Obligations if such payments are not proceeds of, or the result of a realization upon,
Collateral. 
  

 26 

 This Section 3.4(a) is intended for the benefit of, and will be
enforceable as a third party beneficiary by, each present and future holder of Secured Debt Obligations, each present and future Secured Debt Representative and the Collateral Trustee as holder of Parity Liens and Junior Liens. The Secured Debt
Representative of each future Series of Secured Lien Debt will be required to deliver a Collateral Trust Joinder, including a Lien Sharing and Priority Confirmation, to the Collateral Trustee and each other Secured Debt Representative as provided in
Section 3.8 at the time of incurrence of such Series of Secured Lien Debt. 
 In connection with the
application of proceeds pursuant to Section 3.4(a), except as otherwise directed by an Act of Required Debtholders, the Collateral Trustee may sell any non-cash proceeds for cash prior to the application of the proceeds thereof. 
 SECTION 3.5 Powers of the Collateral Trustee. 
 (a) The Collateral Trustee is irrevocably authorized and empowered to enter into and perform its obligations and protect, perfect, exercise and enforce its interest, rights, powers and remedies under the
Security Documents and applicable law and in equity and to act as set forth in this Article 3 or as requested in any lawful directions given to it from time to time in respect of any matter by an Act of Required Debtholders, as applicable, in
accordance with the provisions of this Agreement. 
 (b) No Secured Debt Representative or holder of Secured Debt Obligations
will have any liability whatsoever for any act or omission of the Collateral Trustee. 
 SECTION 3.6 Documents and
Communications. The Collateral Trustee will permit each Secured Debt Representative and each holder of Secured Debt Obligations upon reasonable written notice from time to time to inspect and copy, at the cost and expense of the party requesting
such copies, any and all Security Documents and other documents, notices, certificates, instructions or communications received by the Collateral Trustee in its capacity as such. 
 SECTION 3.7 For Sole and Exclusive Benefit of Holders of Secured Debt Obligations. The Collateral Trustee will accept, hold,
administer and enforce all Liens on the Collateral at any time transferred or delivered to it and all other interests, rights, powers and remedies at any time granted to or enforceable by the Collateral Trustee and all other property of the Trust
Estates solely and exclusively for the benefit of the current and future holders of current and future Secured Debt Obligations, and will distribute all proceeds received by it in realization thereon or from enforcement thereof solely and
exclusively pursuant to the provisions of Section 3.4. 
 SECTION 3.8 Additional Secured Debt. 
 (a) The Collateral Trustee will, as collateral trustee hereunder, perform its undertakings set forth in Section 3.1(a) with respect to
each holder of Secured Debt Obligations of a Series of Secured Lien Debt that is issued or incurred after the date hereof (including any refinancing or replacement of a Series of Secured Lien Debt) that: 
 (1) holds Secured Debt Obligations that are identified as Junior Lien Debt or Parity Lien Debt in accordance with the
procedures set forth in Section 3.8(b); and 
  

 27 

 (2) signs, through its designated Secured Debt Representative identified
pursuant to Section 3.8(b), a Collateral Trust Joinder and delivers the same to the Collateral Trustee and each other Secured Debt Representative at the time of incurrence of such Series of Secured Lien Debt. 
 (b) EFH and EFIH will be permitted to designate as an additional holder of Secured Debt Obligations hereunder each Person who is, or who
becomes, the registered holder of Junior Lien Debt or the registered holder of Parity Lien Debt incurred by EFH or EFIH after the date of this Agreement in accordance with the terms of all applicable Secured Debt Documents. The Company may only
effect such designation by delivering to the Collateral Trustee and each Secured Debt Representative an Additional Secured Debt Designation stating that: 
 (1) EFH or EFIH intends to incur additional Secured Debt (“Additional Secured Debt”) which will either be (i) Parity Lien Debt permitted by each applicable
Secured Debt Document to be secured by a Parity Lien Equally and Ratably with all previously existing and future Parity Lien Debt or (ii) Junior Lien Debt permitted by each applicable Secured Debt Document to be secured with a Junior Lien
Equally and Ratably with all previously existing and future Junior Lien Debt; 
 (2) specifying the name and
address of the Secured Debt Representative for such series of Additional Secured Debt for purposes of Section 7.7; and 
 (3) EFH or EFIH, as applicable, has duly authorized, executed (if applicable) and recorded (or caused to be recorded) in each appropriate governmental office all relevant filings and recordations to
ensure that the Additional Secured Debt is secured by the Collateral in accordance with the Security Documents. 
 Although EFIH
shall be required to deliver a copy of each Additional Secured Debt Designation and each Collateral Trust Joinder to each then existing Secured Debt Representative, the failure to so deliver a copy of the Additional Secured Debt Designation and/or
Collateral Trust Joinder to any then existing Secured Debt Representative shall not affect the status of such debt as Additional Secured Debt if the other requirements of this Section 3.8 are complied with. Notwithstanding the foregoing,
nothing in this Agreement will be construed to allow EFH or EFIH to incur additional Indebtedness unless otherwise permitted by the terms of all applicable Secured Debt Documents. 
 The Security Documents creating or evidencing the Parity Liens and the Junior Liens and Guarantees for the Parity Lien Obligations and the
Junior Lien Obligations shall be in all material respects the same forms of documents other than with respect to the first lien and the second lien nature of the Obligations thereunder. 
  

 28

the release of that Collateral has been given by holders of 66 2/3% of the aggregate principal amount of Parity Lien Debt at the time outstanding voting together as one class, as provided for in the applicable Secured Debt Documents; provided that if an Event of
Default under the Notes or an event of default with respect to any other Secured Debt has occurred and is continuing at the time of the solicitation of any such consent, the consent of holders of 66 2/3% of the aggregate principal amount of Secured Debt as the time

documentation, in each case as required by the Indenture and the Security Documents, in a form satisfactory to the Collateral Trustee. 
 and,
in each case, upon request of EFIH, at EFIH’s expense, the Collateral Trustee will execute (with such acknowledgements and/or notarizations as are required) any such documents as provided by EFIH and deliver evidence of such release to EFIH in
the form provided by EFIH; provided, however, to the extent EFIH requests the Collateral Trustee to deliver evidence of the release of the Collateral in accordance with this Section 4.1(a), EFIH will deliver to the Collateral Trustee an
Officer’s Certificate to the effect that no release of Collateral pursuant to this Section 4.1(a) violated the terms of any Secured Debt Documents. 
 (b) Other than with respect to any release pursuant to clause (2), (3), (4), (5) or (9) of Section 4.1(a) hereof, the Collateral Trustee agrees for the benefit of EFIH that if the
Collateral Trustee at any time receives: 
 (1) an Officer’s Certificate stating that (A) the signing
officer has read Article 4 of this Agreement and understands the provisions and the definitions relating hereto, (B) such officer has made such examination or investigation as is necessary to enable him or her to express an informed
opinion as to whether or not the conditions precedent in this Agreement and all other Secured Debt Documents, if any, relating to the release of the Collateral have been complied with and (C) in the opinion of such officer, such conditions
precedent, if any, have been complied with; and 
  

 30 

 (2) the proposed instrument or instruments releasing such Lien as to such
property in recordable form, if applicable; 
 then the Collateral Trustee, EFIH’s expense, will execute (with such acknowledgements and/or
notarizations as are required) and deliver such release to EFIH on or before the later of (x) the date specified in such request for such release and (y) the fifth Business Day after the date of receipt of the items required by this
Section 4.1(c) by the Collateral Trustee. 
 (c) The Collateral Trustee hereby agrees that: 
 (1) in the case of any release pursuant to clause (8) of Section 4.1(a), if the terms of any such sale, transfer or
other disposition require the payment of the purchase price to be contemporaneous with the delivery of the applicable release, then, at the written request of and at the expense of EFIH, the Collateral Trustee will either (A) be present at and
deliver the release at the closing of such transaction or (B) deliver the release under customary escrow arrangements that permit such contemporaneous payment and delivery of the release; and 
 (2) at any time when a Secured Debt Default under a Series of Secured Lien Debt that constitutes Junior Lien Debt has

 (d) Each Secured Debt Representative hereby agrees that promptly after the receipt by it of any notice from the Collateral
Trustee pursuant to Section 4.1(c)(2), such Secured Debt Representative will deliver a copy of such notice to each registered holder of the Series of Parity Lien Debt or Series of Junior Lien Debt for which it acts as Secured Debt
Representative. 
 SECTION 4.2 Delivery of Copies to Secured Debt Representatives. The Company will deliver to each
Secured Debt Representative a copy of (i) each Secured Debt Document and (ii) each Officer’s Certificate delivered to the Collateral Trustee pursuant to Section 4.1(b), together with copies of all documents delivered to the
Collateral Trustee with such Officer’s Certificate. 
 SECTION 4.3 Collateral Trustee not Required to Serve, File,
Register or Record. The Collateral Trustee is not required to serve, file, register or record any instrument releasing or subordinating its Liens on any Collateral; provided, however, that if, in connection with any release pursuant to
Article 4 of this Agreement, EFIH shall make a written demand for a termination statement under Section 9-513(c) of the UCC, the Collateral Trustee shall comply with the written request of such EFIH to comply with the requirements of such UCC
provision; provided, further, that the Collateral Trustee must first confirm with the Secured Debt Representatives that the requirements of such UCC provisions have been satisfied. 
 ARTICLE 5. IMMUNITIES OF THE COLLATERAL TRUSTEE 
 SECTION 5.1 No Implied Duty. The Collateral Trustee will not have any fiduciary duties nor will it have responsibilities or obligations other than those expressly

  

 31 

 
assumed by it in this Agreement and the other Security Documents to which it is a party. The Collateral Trustee will not be required to take any action that is contrary to applicable law or any
provision of this Agreement or the other Security Documents to which it is a party. 
 SECTION 5.2 Appointment of Agents and
Advisors. The Collateral Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys, accountants, appraisers or other experts or advisors selected by it in good
faith as it may reasonably require and will not be responsible for any misconduct or negligence on the part of any of them. 
 SECTION 5.3 Other Agreements. The Collateral Trustee has accepted and is bound by the Security Documents executed by the Collateral Trustee as of the date of this Agreement and, as directed by an Act of Required
Debtholders, the Collateral Trustee shall execute additional Security Documents delivered to it after the date of this Agreement; provided, however, that such additional Security Documents do not adversely affect the rights, privileges,
benefits and immunities of the Collateral Trustee. The Collateral Trustee will not otherwise be bound by, or be held obligated by, the provisions of any credit agreement, indenture or other agreement governing Secured Debt (other than this
Agreement and the other Security Documents to which it is a party). 
 SECTION 5.4 Solicitation of Instructions.

 (a) The Collateral Trustee may at any time solicit written confirmatory instructions, in the form of an Act of Required
Debtholders, an Officer’s Certificate or an order of a court of competent jurisdiction, as to any action that it may be requested or required to take, or that it may propose to take, in the performance of any of its obligations under this
Agreement or the other Security Documents. 
 (b) No written direction given to the Collateral Trustee by an Act of Required
Debtholders, that in the reasonable judgment of the Collateral Trustee imposes, purports to impose or might reasonably be expected to impose upon the Collateral Trustee any obligation or liability not set forth in or arising under this Agreement and
the other Security Documents will be binding upon the Collateral Trustee unless the Collateral Trustee elects, at its sole option, to accept such direction. 
 SECTION 5.5 Limitation of Liability. The Collateral Trustee will not be responsible or liable for any action taken or omitted to be taken by it hereunder or under any other Security Document,
except for its own gross negligence, bad faith or willful misconduct as determined by a court of competent jurisdiction. 
 SECTION 5.6 Documents in Satisfactory Form. The Collateral Trustee will be entitled to require that all agreements, certificates, opinions, instruments and other documents at any time submitted to it, including those expressly
provided for in this Agreement, be delivered to it in a form and with substantive provisions reasonably satisfactory to it. 
 SECTION 5.7 Entitled to Rely. The Collateral Trustee may seek and rely upon, and shall be fully protected in relying upon, any judicial order or judgment, upon any advice, opinion or statement of legal counsel, independent
consultants and other experts selected

  

 32 

 
by it in good faith and upon any certification, instruction, notice or other writing delivered to it by EFIH in compliance with the provisions of this Agreement or delivered to it by any Secured
Debt Representative as to the holders of Secured Debt Obligations for whom it acts, without being required to determine the authenticity thereof or the correctness of any fact stated therein or the propriety or validity of service thereof. The
Collateral Trustee may act in reliance upon any instrument comporting with the provisions of this Agreement or any signature reasonably believed by it to be genuine and may assume that any Person purporting to give notice or receipt or advice or
make any statement or execute any document in connection with the provisions hereof or the other Security Documents has been duly authorized to do so. To the extent an Officer’s Certificate or opinion of counsel is required or permitted under
this Agreement to be delivered to the Collateral Trustee in respect of any matter, the Collateral Trustee may rely conclusively on an Officer’s Certificate or opinion of counsel as to such matter and such Officer’s Certificate or opinion
of counsel shall be full warranty and protection to the Collateral Trustee for any action taken, suffered or omitted by it under the provisions of this Agreement and the other Security Documents. 
 SECTION 5.8 Secured Debt Default. The Collateral Trustee will not be required to inquire as to the occurrence or absence of any
Secured Debt Default and will not be affected by or required to act upon any notice or knowledge as to the occurrence of any Secured Debt Default unless and until it is directed by an Act of Required Debtholders. 
 SECTION 5.9 Actions by Collateral Trustee. As to any matter not expressly provided for by this Agreement or the other Security
Documents, the Collateral Trustee will act or refrain from acting as directed by an Act of Required Debtholders and will be fully protected if it does so, and any action taken, suffered or omitted pursuant hereto or thereto shall be binding on the
holders of Secured Debt Obligations. 
 SECTION 5.10 Security or Indemnity in Favor of the Collateral Trustee. The
Collateral Trustee will not be required to advance or expend any funds or otherwise incur any financial liability in the performance of its duties or the exercise of its powers or rights hereunder unless it has been provided with security or
indemnity reasonably satisfactory to it against any and all liability or expense which may be incurred by it by reason of taking or continuing to take such action. 
 SECTION 5.11 Rights of the Collateral Trustee. In the event there is any bona fide, good faith disagreement between the other parties to this Agreement or any of the other Security Documents
resulting in adverse claims being made in connection with Collateral held by the Collateral Trustee and the terms of this Agreement or any of the other Security Documents do not unambiguously mandate the action the Collateral Trustee is to take or
not to take in connection therewith under the circumstances then existing, or the Collateral Trustee is in doubt as to what action it is required to take or not to take hereunder or under the other Security Documents, it will be entitled to refrain
from taking any action (and will incur no liability for doing so) until directed otherwise in writing by a request signed jointly by the parties hereto entitled to give such direction or by order of a court of competent jurisdiction. 
  

 33 

 SECTION 5.12 Limitations on Duty of Collateral Trustee in Respect of Collateral.

 (a) Beyond the exercise of reasonable care in the custody of Collateral in its possession, the Collateral Trustee will have
no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Collateral
Trustee will not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on the
Collateral. The Collateral Trustee will be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property, and the
Collateral Trustee will not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Trustee in
good faith. 
 (b) The Collateral Trustee will not be responsible for the existence, genuineness or value of any of the
Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action
or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Collateral Trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of
EFIH or any Successor Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Collateral Trustee hereby disclaims
any representation or warranty to the present and future holders of the Secured Debt Obligations concerning the perfection of the Liens granted hereunder or in the value of any of the Collateral. 
 (c) In no event shall the Collateral Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind
whatsoever (including, but not limited to, loss of profit) irrespective of whether the Collateral Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 
 SECTION 5.13 Assumption of Rights, Not Assumption of Duties. Notwithstanding anything to the contrary contained herein: 

(1) each of the parties thereto will remain liable under each of the Security Documents (other than this Agreement) to the
extent set forth therein to perform all of their respective duties and obligations thereunder to the same extent as if this Agreement had not been executed; 
 (2) the exercise by the Collateral Trustee of any of its rights, remedies or powers hereunder will not release such parties
from any of their respective duties or obligations under the other Security Documents; and 
  

 34 

 (3) the Collateral Trustee will not be obligated to perform any of the
obligations or duties of any of the parties thereunder other than the Collateral Trustee. 
 SECTION 5.14 No Liability for
Clean Up of Hazardous Materials. In the event that the Collateral Trustee is required to acquire title to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any fiduciary or trust
obligation for the benefit of another, which in the Collateral Trustee’s sole discretion may cause the Collateral Trustee to be considered an “owner or operator” under any environmental laws or otherwise cause the Collateral Trustee
to incur, or be exposed to, any environmental liability or any liability under any other federal, state or local law, the Collateral Trustee reserves the right, instead of taking such action, either to resign as Collateral Trustee or to arrange for
the transfer of the title or control of the asset to a court appointed receiver. The Collateral Trustee will not be liable to any Person for any environmental liability or any environmental claims or contribution actions under any federal, state or
local law, rule or regulation by reason of the Collateral Trustee’s actions and conduct as authorized, empowered and directed hereunder or relating to any kind of discharge or release or threatened discharge or release of any hazardous
materials into the environment. 
 ARTICLE 6. RESIGNATION AND REMOVAL OF THE COLLATERAL TRUSTEE 
 SECTION 6.1 Resignation or Removal of Collateral Trustee. Subject to the appointment of a successor Collateral Trustee as provided in
Section 6.2 and the acceptance of such appointment by the successor Collateral Trustee: 
 (a) the Collateral Trustee may
resign at any time by giving notice of resignation to each Secured Debt Representative and EFIH; and 
 (b) the Collateral
Trustee may be removed at any time, with or without cause, by an Act of Required Debtholders. 
 SECTION 6.2 Appointment of
Successor Collateral Trustee. 
 (a) Upon any resignation or removal of the Collateral Trustee pursuant to Section 6.1,
a successor Collateral Trustee may be appointed by EFIH, so long as no Secured Debt Default has occurred and is continuing and if a Secured Debt Default has occurred and is continuing, by an Act of the Required Debtholders. Within one year after a
successor Collateral Trustee appointed by EFIH takes office, the holders of Secured Debt may, by an Act of Required Debtholders appoint a successor Collateral Trustee to replace the successor Collateral Trustee appoint by EFIH. If no successor
Collateral Trustee has been so appointed and accepted such appointment within 45 days after the predecessor Collateral Trustee gave notice of resignation or was removed, the retiring Collateral Trustee may (at the expense of EFIH), at its option,
appoint a successor Collateral Trustee, or petition a court of competent jurisdiction for appointment of a successor Collateral Trustee, which must be a bank or trust company: 
 (1) authorized to exercise corporate trust powers; 
 (2) having a combined capital and surplus of at least $100,000,000; and 
  

 35 

 (3) maintaining an office in any state of the United States. 
 (b) The Collateral Trustee will fulfill its obligations hereunder until a successor Collateral Trustee meeting the requirements of this
Section 6.2 has accepted its appointment as Collateral Trustee and the provisions of Section 6.3 have been satisfied. 
 SECTION 6.3 Succession. When the Person so appointed as successor Collateral Trustee pursuant Section 6.2 accepts such appointment: 
 (1) such Person will succeed to and become vested with all the rights, powers, privileges and duties of the predecessor Collateral Trustee, and the predecessor Collateral Trustee will be discharged from
its duties and obligations hereunder; and 
 (2) the predecessor Collateral Trustee will (at the expense of EFIH)
promptly transfer all Liens and collateral security and other property of the Trust Estates within its possession or control to the possession or control of the successor Collateral Trustee and will execute instruments and assignments as may be
necessary or reasonably requested by the successor Collateral Trustee to transfer to the successor Collateral Trustee all Liens, interests, rights, powers and remedies of the predecessor Collateral Trustee in respect of the Security Documents or the
Trust Estates. 
 Thereafter the predecessor Collateral Trustee will remain entitled to enforce the immunities granted to it in Article 5
and the provisions of Sections 7.10 and 7.11. 
 SECTION 6.4 Merger, Conversion or Consolidation of Collateral
Trustee. Any Person into which the Collateral Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Collateral Trustee shall be a party, or any
Person succeeding to the business of the Collateral Trustee shall be the successor of the Collateral Trustee pursuant to Section 6.3, provided that (i) without the execution or filing of any paper with any party hereto or any
further act on the part of any of the parties hereto, except where an instrument of transfer or assignment is required by law to effect such succession, anything herein to the contrary notwithstanding, such Person satisfies the eligibility
requirements specified in clauses (1) through (3) of Section 6.2 and (ii) prior to any such merger, conversion or consolidation, the Collateral Trustee shall have notified EFIH, each Parity Lien Representative and each Junior
Lien Representative thereof in writing. 
 ARTICLE 7. MISCELLANEOUS PROVISIONS 
 SECTION 7.1 Amendment. 
 (a) No amendment or supplement to the provisions of this Agreement or any other Security Document will be effective without the approval of the Collateral Trustee acting as directed by an Act of Required
Debtholders, except that: 
 (1) any amendment or supplement that has the effect solely of (i) adding or
maintaining Collateral, securing additional Secured Debt that was otherwise permitted by the terms of the Secured Debt Documents to be secured by the Collateral or

  

 36 

 
preserving, perfecting or establishing the priority of the Liens thereon or the rights of the Collateral Trustee therein, (ii) curing any ambiguity, defect or inconsistency;
(iii) providing for the assumption of EFIH’s obligations under any Security Document in the case of a merger or consolidation or sale of all or substantially all of EFIH’s assets; or (iv) making any change that would provide any
additional rights or benefits to the holders of Secured Debt Obligations, the Secured Debt Representatives or the Collateral Trustee or that does not adversely affect the legal rights under any Secured Debt Document of any holder of Secured Debt
Obligations, the Secured Debt Representatives or the Collateral Trustee, will, in each case, become effective when executed and delivered by EFIH and the Collateral Trustee; 
 (2) no amendment or supplement that reduces, impairs or adversely affects the right of any holder of Secured Debt
Obligations: 
 (A) to vote its outstanding Secured Debt as to any matter requiring (i) an Act of Required
Debtholders or (ii) direction by the Required Parity Lien Debtholders or the Required Junior Lien Debtholders, (or amends the provisions of this clause (2) or the definition of “Act of Required Debtholders,”
“Required Parity Lien Debtholders” or “Required Junior Lien Debtholders”), 
 (B) to share, in the order of application described in Section 3.4, in the proceeds of enforcement of or realization on any Collateral that has not been released in accordance with the provisions described in Section 4.1, or

 (C) to require that Liens securing Secured Debt Obligations be released only as set forth in the provisions
described in Section 4.1, 
 will become effective without the consent of the requisite percentage or number of holders of each Series of
Secured Lien Debt so affected under the applicable Secured Debt Documents; and 
 (3) no amendment or supplement
that imposes any obligation upon the Collateral Trustee or any Secured Debt Representative or adversely affects the rights of the Collateral Trustee, as determined by the Collateral Trustee in its sole discretion, or any Secured Debt Representative,
respectively, in its individual capacity as such will become effective without the consent of the Collateral Trustee or such Secured Debt Representative, respectively. 
 (b) Notwithstanding Section 7.1(a) but subject to Sections 7.1(a)(2) and 7.1(a)(3): 
 (1) any Security Document that secures Junior Lien Obligations (but not Parity Lien Obligations) may be amended or supplemented with the approval of the Collateral Trustee acting as directed in writing by
the Required Junior Lien Debtholders, unless such amendment or supplement would not be permitted under the terms of this Agreement or the other Parity Lien Documents; and 
  

 37 

 (2) any amendment or waiver of, or any consent under, any provision of this
Agreement or any other Security Document that secures Parity Lien Obligations (except any such amendment, waiver or consent that releases Collateral with respect to which any consent of holders of Junior Lien Debt is required pursuant to this
Agreement, which will be governed by the provision in Section 7.1(a)) will apply automatically to any comparable provision of any comparable Junior Lien Document without the consent of or notice to any holder of Junior Lien Obligations and
without any action by EFH, EFIH, any holder of Notes or other Junior Lien Obligations. 
 (c) The Collateral Trustee will not
enter into any amendment or supplement unless it has received an Officer’s Certificate to the effect that such amendment or supplement will not result in a breach of any provision or covenant contained in any of the Secured Debt Documents.
Prior to executing any amendment or supplement pursuant to this Section 7.1, the Collateral Trustee will be entitled to receive an opinion of counsel of EFIH (which may be provided by internal counsel to EFIH) to the effect that the execution
of such document is authorized or permitted hereunder, that such document is the legal, valid and binding obligation of EFIH, enforceable against it in accordance with its terms, subject to customary exceptions, and with respect to amendments adding
Collateral, an opinion of counsel of EFIH (which may be provided by internal counsel to EFIH) addressing customary perfection, and if such additional Collateral consists of equity interests of any Person, priority matters with respect to such
additional Collateral (subject to customary qualifications and assumptions). 
 (d) The holders of Junior Lien Obligations and
the Junior Lien Representatives agree that each Security Document that secures Junior Lien Obligations (but not also securing Parity Lien Obligations) will include language substantially to the effect of the following: 
 “Notwithstanding anything herein to the contrary, the lien and security interest granted to the Collateral Trustee pursuant to this
Agreement and the exercise of any right or remedy by such Collateral Trustee hereunder are subject to the provisions of the Collateral Trust Agreement, dated as of [—], 2009, among EFIH, The Bank of
New York Mellon Trust Company, N.A., as Trustee under the EFH Indenture (as defined therein), The Bank of New York Mellon Trust Company, N.A., as Trustee under the EFIH Indenture (as defined therein) and The Bank of New York Mellon Trust Company,
N.A., as Collateral Trustee (as amended, supplemented, amended and restated or otherwise modified and in effect from time to time, the “Collateral Trust Agreement”). In the event of any conflict between the terms of the Collateral
Trust Agreement and this Agreement, the terms of the Collateral Trust Agreement will govern.” 
 ; provided, however, that if the
jurisdiction in which any such Junior Lien Document will be filed prohibits the inclusion of the language above or would prevent a document containing such language from being recorded, the Junior Lien Representatives and the Parity Lien
Representatives agree, prior to such Junior Lien Document being entered into, to negotiate in good faith replacement language stating that the lien and security interest granted under such Junior Lien Document is subject to the provisions of this
Agreement. 
 SECTION 7.2 Voting. In connection with any matter under this Agreement requiring a vote of holders of
Secured Debt, each Series of Secured Lien Debt will

  

 38 

 
cast its votes in accordance with the Secured Debt Documents governing such Series of Secured Lien Debt. The amount of Secured Debt to be voted by a Series of Secured Lien Debt will equal
(1) the aggregate outstanding principal amount of Secured Debt held by such Series of Secured Lien Debt (including outstanding letters of credit whether or not then available or drawn), plus (2) the aggregate unfunded commitments to
extend credit which, when funded, would constitute Indebtedness of such Series of Secured Lien Debt. Following and in accordance with the outcome of the applicable vote under its Secured Debt Documents, the Secured Debt Representative of each Series
of Secured Lien Debt will vote the total amount of Secured Debt under that Series of Secured Lien Debt as a block in respect of any vote under this Agreement. 
 SECTION 7.3 Further Assurances. 
 (a) EFIH will do or cause to be done all
acts and things that may be required, or that the Collateral Trustee from time to time may reasonably request, to assure and confirm that the Collateral Trustee holds, for the benefit of the Secured Debt Representatives and holders of Secured Debt
Obligations, duly created and enforceable and perfected Liens upon the Collateral (including any property or assets that are acquired or otherwise become Collateral after the date hereof), in each case as contemplated by, and with the Lien priority
required under, the Secured Debt Documents. 
 (b) Upon the reasonable request of the Collateral Trustee or any Secured Debt
Representative at any time and from time to time, EFIH, at its own expense, will promptly execute, acknowledge and deliver such additional security documents, instruments, certificates, notices and other documents, and take such other actions as may
be reasonably required, or that the Collateral Trustee may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred thereby, in each case as contemplated by the Secured Debt Documents for the
benefit of holders of Secured Debt Obligations. 
 (c) Upon the request of the Collateral Trustee, EFIH will permit the
Collateral Trustee or any of its agents or representatives, at reasonable times and intervals upon reasonable prior notice during regular business hours, to visit its offices and sites and inspect any of the Collateral and to discuss matters
relating to the Collateral with its officers at EFIH’s expense. EFIH shall, at any reasonable time and from time to time upon reasonable prior notice during regular business hours, permit the Collateral Trustee or any of its agents or
representatives to examine and make copies of and abstracts from the records and books of account of EFIH and its Subsidiaries, all at EFIH’s expense. 
 SECTION 7.4 Perfection of Junior Trust Estate. Solely for purposes of perfecting the Liens of the Collateral Trustee in its capacity as agent of the holders of Junior Lien Obligations and the
Junior Lien Representatives in any portion of the Junior Trust Estate in the possession or control of the Collateral Trustee (or its agents or bailees) as part of the Senior Trust Estate including, without limitation, any instruments, goods,
negotiable documents, tangible chattel paper, electronic chattel paper, certificated securities, money, deposit accounts and securities accounts, the Collateral Trustee, the holders of Parity Lien Obligations and the Parity Lien Representatives
hereby acknowledge that the Collateral Trustee also holds such property as agent for the benefit of the Collateral Trustee for the benefit of the holders of Junior Lien Obligations and the Junior Lien Representatives. 
  

 39 

 SECTION 7.5 Successors and Assigns. 
 (a) Except as provided in Section 5.2, the Collateral Trustee may not, in its capacity as such, delegate any of its duties or assign
any of its rights hereunder, and any attempted delegation or assignment of any such duties or rights will be null and void. All obligations of the Collateral Trustee hereunder will inure to the sole and exclusive benefit of, and be enforceable by,
each Secured Debt Representative and each present and future holder of Secured Debt Obligations, each of whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns.

 (b) The Company may not delegate any of its duties or assign any of its rights hereunder, and any attempted delegation or
assignment of any such duties or rights will be null and void. All obligations of EFIH will inure to the sole and exclusive benefit of, and be enforceable by, the Collateral Trustee, each Secured Debt Representative and each present and future
holder of Secured Debt Obligations, each of whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns. 
 SECTION 7.6 Delay and Waiver. No failure to exercise, no course of dealing with respect to the exercise of, and no delay in
exercising, any right, power or remedy arising under this Agreement or any of the other Security Documents will impair any such right, power or remedy or operate as a waiver thereof. No single or partial exercise of any such right, power or remedy
will preclude any other or future exercise thereof or the exercise of any other right, power or remedy. The remedies herein are cumulative and are not exclusive of any remedies provided by law.

provided, no Indemnitee will be entitled to indemnification hereunder with respect to any Indemnified Liability to the extent such Indemnified Liability is found by a final and nonappealable decision of a court of competent jurisdiction to

Documents. 
 SECTION 7.15 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW
OF THE STATE OF NEW YORK. 
 SECTION 7.16 Consent to Jurisdiction. All judicial proceedings brought against any party
hereto arising out of or relating to this Agreement or any of the other Security Documents may be brought in any state or federal court of competent jurisdiction in the State, County and City of New York. By executing and delivering this Agreement,

 (1) accepts generally and unconditionally
the nonexclusive jurisdiction and venue of such courts; 
 (2) waives any defense of forum non conveniens;

 (3) agrees that service of all process in any such proceeding in any such court may be made by registered or
certified mail, return receipt requested, to such party at its address provided in accordance with Section 7.7;

and 
 (5) agrees that each party hereto retains the right to serve process in any other manner permitted by law
or to bring proceedings against any party in the courts of any other jurisdiction. 
 SECTION 7.17 Waiver of Jury Trial.
Each party to this Agreement waives its rights to a jury trial of any claim or cause of action based upon or arising under this Agreement or any of the other Security Documents or any dealings between them relating to the subject matter of this
Agreement or the intents and purposes of the other Security Documents. The scope of this waiver is intended to be all-encompassing of any and all disputes that may be

  

 44 

 
filed in any court and that relate to the subject matter of this Agreement and the other Security Documents, including contract claims, tort claims, breach of duty claims and all other common law
and statutory claims. Each party to this Agreement acknowledges that this waiver is a material inducement to enter into a business relationship, that each party hereto has already relied on this waiver in entering into this Agreement, and that each
party hereto will continue to rely on this waiver in its related future dealings. Each party hereto further warrants and represents that it has reviewed this waiver with its legal counsel and that it knowingly and voluntarily waives its jury trial
rights following consultation with legal counsel. This waiver is irrevocable, meaning that it may not be modified either orally or in writing (other than by a mutual written waiver specifically referring to this Section 7.17 and executed by
each of the parties hereto), and this waiver will apply to any subsequent amendments, renewals, supplements or modifications of or to this Agreement or any of the other Security Documents or to any other documents or agreements relating thereto. In
the event of litigation, this Agreement may be filed as a written consent to a trial by the court. 
 SECTION 7.18
Counterparts. This Agreement may be executed in any number of counterparts (including by facsimile or electronic transmission), each of which when so executed and delivered will be deemed an original, but all such counterparts together will
constitute but one and the same instrument. 
 SECTION 7.19 Effectiveness. This Agreement will become effective upon the
execution of a counterpart hereof by each of the parties hereto on the date hereof and receipt by each party of written notification of such execution and written or telephonic authorization of delivery thereof. 
 SECTION 7.20 Successor Company. EFIH will cause each Person that becomes a Successor Company or is required by any Secured Debt
Document to become a party to this Agreement to become a party to this Agreement, for all purposes of this Agreement, by causing such Person to execute and deliver to the Collateral Trustee a Collateral Trust Joinder, whereupon such Person will be
bound by the terms hereof to the same extent as if it had executed and delivered this Agreement as of the date hereof. EFIH shall promptly provide each Secured Debt Representative with a copy of each Collateral Trust Joinder executed and delivered
pursuant to this Section 7.20; provided, however, that the failure to so deliver a copy of the Collateral Trust Joinder to any then existing Secured Debt Representative shall not affect the inclusion of such Person as a party hereto if
the other requirements of this Section 7.20 are complied with. 
 SECTION 7.21 Continuing Nature of this Agreement.
This Agreement, including the subordination provisions hereof, will be reinstated if at any time any payment or distribution in respect of any of the Parity Lien Obligations is rescinded or must otherwise be returned in an Insolvency or Liquidation
Proceeding or otherwise by any holder of Parity Lien Obligations or Parity Lien Representative or any representative of any such party (whether by demand, settlement, litigation or otherwise). In the event that all or any part of a payment or
distribution made with respect to the Parity Lien Obligations is recovered from any holder of Parity Lien Obligations or any Parity Lien Representative in an Insolvency or Liquidation Proceeding or otherwise, such payment or distribution received by
any holder of Junior Lien Obligations or Junior Lien Representative with respect to the Junior Lien Obligations from the

  

 45 

 
proceeds of any Collateral at any time after the date of the payment or distribution that is so recovered, whether pursuant to a right of subrogation or otherwise, that Junior Lien Representative
or that holder of a Junior Lien Obligation, as the case may be, will forthwith deliver the same to the Collateral Trustee, for the account of the holders of the Parity Lien Obligations and other Obligations secured by a Permitted Prior Lien, to be
applied in accordance with Section 3.4. Until so delivered, such proceeds will be held by that Junior Lien Representative or that holder of a Junior Lien Obligation, as the case may be, for the benefit of the holders of the Parity Lien
Obligations and other Obligations secured by a Permitted Prior Lien. 
 SECTION 7.22 Insolvency. This Agreement will be
applicable both before and after the commencement of any Insolvency or Liquidation Proceeding by or against EFIH. The relative rights, as provided for in this Agreement, will continue after the commencement of any such Insolvency or Liquidation
Proceeding on the same basis as prior to the date of the commencement of any such case, as provided in this Agreement. 
 SECTION 7.23 Rights and Immunities of Secured Debt Representatives. The Secured Debt Representatives will be entitled to all of the rights, protections, immunities and indemnities set forth in the Indentures and any future Secured
Debt Representative will be entitled to all of the rights, protections, immunities and indemnities set forth in the credit agreement, indenture or other agreement governing the applicable Secured Debt with respect to which such Person is acting or
will act as representative, in each case as if specifically set forth herein. In no event will any Secured Debt Representative be liable for any act or omission on the part of EFIH or the Collateral Trustee hereunder. 
 SECTION 7.24 Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the USA Patriot Act the
Collateral Trustee, like all financial institutions, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with it. The parties to this Agreement agree
that they will provide the Collateral Trustee with such information as it may reasonably request in order for the Collateral Trustee to satisfy the requirements of the USA Patriot Act. 
 SECTION 7.25 Force Majeure. In no event shall the Collateral Trustee be responsible or liable for any failure or delay in the
performance of its obligations under this Agreement arising out of or caused by, directly or indirectly, forces beyond its reasonable control, including without limitation strikes, work stoppages, accidents, acts of war or terrorism, civil or
military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software or hardware) services.
