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

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

 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 November 16, 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

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.

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.

 EXHIBIT A 
 to Collateral Trust Agreement 
 FORM OF 
 ADDITIONAL SECURED DEBT DESIGNATION 
 Reference is made to the Collateral Trust Agreement dated as of [—], 2009 (as amended, supplemented, amended and restated or otherwise modified and in
