	Re:	Instructions to Issue Shares 

 Ladies and Gentlemen: 
 Reference is made to those certain Senior Unsecured
Mandatorily Convertible Debentures and Senior Convertible Unsecured Debentures dated at various times from August 2010 through January 2011 (collectively, the “Debentures;” certain terms used herein and not defined herein are
used herein as defined in the Debentures), by and between Ampio Pharmaceuticals, Inc., a Delaware corporation (the “Company” or “Ampio”) and the holders of the Debentures identified on Exhibit A hereto
(the “Holders” or the “Purchasers”). Pursuant to the terms of the Debentures, the Debentures were to automatically convert into shares of common stock of the Company at the lower of $1.75 per share or
the price of an underwritten offering, on the earlier of (1) completion of an underwritten offering of the Company’s common stock in the amount of $10 million or more, or (2) March 31, 2010. However, pursuant to mutual agreements
entered into between the Company and all of the Holders, the Holders have agreed to an immediate conversion of the Debentures at $1.75 per share. On February 28, 2011, the Board of Directors of the Company authorized the issuance of an
aggregate of 1,281,852 shares of the Company’s common stock, par value $0.0001 per share (the “Conversion Shares”), in extinguishment of the outstanding principal of the Debentures and accrued interest thereon to
February 22, 2011. The Company will be making a cash payment of interest on the Debentures for the period from February 22, 2011 to February 28, 2011. 
 Reference also is made to that certain Warrant to purchase shares of common stock dated as of the date of the Debentures (the “Warrants”), issued by the Company, pursuant to which
the Holders may purchase up to an aggregate of 256,389 shares of the Company’s Common Stock., which are referred to herein as the “Warrant Shares.” The Conversion Shares, together with the Warrant Shares are
hereinafter referred to as the “Shares.” 
 This irrevocable letter of instructions shall serve as the
authorization and direction of the Company to Corporate Stock Transfer, Inc. (“you” or “your” or “Corporate Stock Transfer”) to issue certificates of Ampio common stock
representing the Shares to the Holders (i) in connection with the conversion of the Debentures, and (ii) on exercise of the Warrants, as follows: 
 1. Upon your receipt of these instructions, you shall as soon as practicable, but in no event later than two (2) Trading Days (as defined below) after receipt of such instructions, issue and
surrender to a common carrier for overnight delivery to the Purchasers at the addresses set forth on Exhibit A, the certificates (collectively, the “Certificates”) representing the Conversion Shares, registered in the name of
the Purchasers. For purposes hereof, “Trading Day” shall mean any day on which the New York Stock Exchange is open for customary trading. The Certificates representing the Conversion Shares shall be issued with a restrictive
legend which provides substantially as follows: 
 The securities represented by this certificate have not been registered under
the Securities Act of 1933, as amended (“Act”), and may not be offered or sold except (i) pursuant to an effective registration statement under the Act, (ii) to the extent applicable, pursuant to Rule 144 under the

 Corporate Stock Transfer, Inc. 
 March 10, 2011 
  

 
Act (or any similar rule under such Act relating to the disposition of securities), or (iii) upon the delivery by the holder to the Company of an opinion of counsel, reasonably satisfactory
to counsel to the issuer, stating that an exemption from registration under such Act is available. 
 2. Once the resale of the
Conversion Shares by the Purchasers has been registered with the Securities and Exchange Commission (the “SEC”) under the Company’s registration statement on Form S-1 (the “Registration
Statement”) to be filed with the SEC shortly hereafter, and upon receipt of a legal opinion from Richardson & Patel, LLP, counsel to the Company, that the Conversion Shares have been so registered (which opinion shall also note
that the Registration Statement has been declared effective by the SEC) and upon tender of Certificate(s) by one or more Purchasers to you with a request for legend removal (the “Tender Notice”), you shall within three
(3) Trading Days thereafter (a) issue and deliver to each tendering Purchaser, via a common carrier for overnight delivery, to the address as specified in the Tender Notice, a certificate or certificates free of any restrictive legend and
registered in the name of the Purchaser or its designee, for the Conversion Shares, up to the number of shares evidenced by the Certificate tendered, or (b) on the request of the Purchaser in question, credit such aggregate number of Conversion
Shares to the Purchaser’s or its designees’ balance account with DTC through the Deposit Withdrawal at Custodian (“DWAC”) system, provided the Purchaser causes its bank or broker to initiate the DWAC transaction.
Notwithstanding the foregoing language, in the event the legal opinion is not provided to you as described above, the Certificates representing the Conversion Shares shall continue to bear the restrictive legend. 

3. You shall issue the Warrant Shares to or at the direction of the Company upon exercise of all or a portion of the Warrants held by the
Purchasers (which also are listed on Exhibit A hereto), upon delivery to you of (a) a properly completed and duly executed Notice of Exercise (the “Notice of Exercise”) in the form attached hereto as Exhibit B,
(b) receipt by you of the Exercise Price or confirmation from the Company that it received the Exercise Price, and the expiration of sufficient time so as to allow clearing of any check or confirmation of any wire by which such Exercise Price
was paid, and (c) a legal opinion as to the free transferability of the Shares from Company counsel dated within 90 days from the exercise date; provided, however, that in the event the legal opinion is not provided as described
above, you will issue the Warrant Shares subject to a restrictive legend. The form of delivery of the Warrant Shares (whether by physical delivery or using the DWAC System) shall be undertaken by you as may be requested by each Purchaser, subject to
the prior satisfaction of the conditions in (a), (b), and (c) immediately above. 
 4. The Company understands and agrees
that Corporate Stock Transfer shall not be required to perform any issuances or transfers of the Shares or to otherwise act pursuant to these instructions if (a) the Company violates, or would be in violation of, any terms of the Transfer Agent
Agreement as a result of such issuances or transfers, (b) such an issuance or transfer of Shares would be in violation of any state or federal securities laws or regulations, or (c) the issuances or transfer of the Shares is prohibited or
stopped as required or directed by a court order. 
 5. You understand that a delay in the delivery of Certificates or the
crediting of the Shares as described above, as the case may be, could result in economic loss to the Purchasers and that time is of the essence in your processing of a Tender Notice or Notice of Exercise. 

6. By executing this letter in the space set forth at the bottom hereof you agree on behalf of Corporate Stock Transfer that, to the
extent the applicable Shares being issued will be certificated pursuant to Paragraphs 1, 2 or 3 above, if the date on which a Certificate is submitted to you is more than twelve (12) months following the date of issuance of the Certificate and
(i) the Purchaser tenders to you a signed representation letter in the form set forth on your web site, and (ii) the Company confirms these instructions at or about the time of the Purchaser’s tender, the Certificate may then be
reissued by you without any legend restricting transfer and should not be subject to any stop-transfer restrictions, and shall otherwise be freely transferable on the books and records of the Company. 

7. You shall rely exclusively on this letter, the Tender Notice, if given, and the Notice of Exercise, if given, and shall have no
liability for relying on such instructions or on the Tender Notice or Notice of Exercise, subject to receipt of the legal opinion referenced above and, in the case of a Notice of Exercise, the Company’s receipt of cleared funds in payment of
the Exercise Price. Any Tender Notice or Notice of Exercise delivered hereunder shall constitute an irrevocable instruction to you to process the Certificate in accordance with the terms thereof. Such Tender Notice or Notice of Exercise may be
transmitted to you by fax or any commercially reasonable method.

 8. The Company hereby confirms to you that no instruction other than as
contemplated herein will be given to you by the Company with respect to the matters referenced herein, except as otherwise provided in Paragraph 6. The Company hereby authorizes you, and you shall be obligated, to disregard any contrary
instruction received by or on behalf of the Company or any other person purporting to represent the Company except Richardson & Patel, LLP. 
 9. The Certificates shall bear a restrictive legend as set forth below until such time as the conditions set forth above are satisfied: 

10. By signing below, each individual executing this letter on behalf of an entity represents and warrants that he or she has
authority to so execute this letter on behalf of such entity and thereby bind such entity to the terms and conditions hereof. 

11. The Company agrees to indemnify you and your officers, directors, principals, partners, agents and representatives, and hold
each of them harmless from and against any and all loss, liability, damage, claim or expense (including the reasonable fees and disbursements of its attorneys) incurred by or asserted against you or any of them arising out of or in connection
the instructions set forth herein, the performance of your duties hereunder and otherwise in respect hereof, including the costs and expenses of defending yourself or themselves against any claim or liability hereunder, except that the Company
shall not be liable hereunder as to matters in respect of which it is determined that you have acted with gross negligence or in bad faith. You shall have no liability to the Company in respect to any action taken or any failure to act in respect of
this if such action was taken or omitted to be taken in good faith, and you shall be entitled to rely in this regard on the advice of counsel. 
 12. The Company understands and agrees that it must be current in its account with you at the time or times that you are requested to act in accordance with these instructions and that failure to do so
may result in your being unable to execute these instructions. Furthermore, if Corporate Stock Transfer resigns or is dismissed as the Company’s transfer agent, the Company agrees that this Agreement must be assumed or transferred to another
transfer agent duly registered with the SEC under Section 17A(c) of the Securities Exchange Act of 1934, as amended, and the Company will take prompt action in order to effect such assumption or transfer. 

13. The Company will provide Corporate Stock Transfer with an overnight deliver number to facilitate the delivery of Certificates
representing the Shares that are physically certificated.

 THIS SECOND AMENDED AND RESTATED INDENTURE OF MORTGAGE AND DEED OF TRUST dated as of
January 1, 2011, is between OLD DOMINION ELECTRIC COOPERATIVE, a Virginia utility aggregation cooperative, as Grantor (hereinafter called the “Company”), and BRANCH BANKING AND TRUST COMPANY, a North Carolina
banking corporation, as Trustee (hereinafter called the “Trustee”). 
 RECITALS OF THE COMPANY

 The Company previously entered into an Indenture of Mortgage and Deed of Trust, dated as of May 1, 1992, with a
predecessor trustee (to which the Trustee is the successor) (as amended and supplemented, the “Original Indenture”), pursuant to which the Company issued Bonds (as defined therein) of various series. All Bonds issued under the
Original Indenture were initially secured by a lien on and security interest in substantially all of the tangible assets and certain of the intangible assets of the Company. 
 The Eleventh Supplemental Indenture, dated as of September 1, 2001, to the Original Indenture provides that, upon the satisfaction of certain conditions, the Original Indenture was to be
automatically amended and restated in the form of an Amended and Restated Indenture, dated as of September 1, 2001 (the “Existing Indenture”). 
 The conditions to the effectiveness of the Existing Indenture were satisfied and the Existing Indenture became effective. The Existing Indenture is not of record. Pursuant to the terms of the Existing
Indenture, the Bonds became “Obligations” as defined in the Existing Indenture (the “Pre-Existing Obligations”) which are senior unsecured obligations of the Company. 

The Company now desires that all new notes, bonds and other obligations for the payment of money as hereinafter provided issued on or
after the date hereof in one or more series (hereinafter, “Additional Obligations” and, together with the Pre-Existing Obligations, the “Obligations”), together with all Pre-Existing Obligations Outstanding (as
defined below), shall become governed by and subject to the terms and conditions stated in this Second Amended and Restated Indenture and Deed of Trust. 
 All things have been done which are necessary to amend and restate the Existing Indenture on the terms and conditions set forth herein, including to grant liens on and security interests in certain assets
of the Company as provided herein, and to make Obligations executed by the Company and authenticated and delivered by the Trustee and duly issued by the Company, the valid obligations of the Company, and to constitute this Indenture a valid mortgage
and deed of trust, security agreement and financing statement and contract for the security of the Obligations, in accordance with the terms of the Obligations and this Indenture. 

Accordingly, the parties hereto hereby amend and restate the Existing Indenture and otherwise agree as follows: 

GRANTING CLAUSES 
 NOW, THEREFORE, THIS INDENTURE WITNESSETH, that, to secure the payment of the principal of (and premium, if any) and interest on the Outstanding Secured

 
Obligations (as hereinafter defined) and the performance of the covenants therein and herein contained and to declare the terms and conditions on which the Outstanding Secured Obligations are
secured, and in consideration of the premises and the purchase of Obligations by the Holders (as hereinafter defined) of, or loans and other obligations evidenced by, the Obligations, the Company by these presents does grant, bargain, sell,
alienate, remise, release, convey, assign, transfer, mortgage, hypothecate, pledge, set over and confirm to the Trustee, in trust, all property, rights, privileges and franchises of the Company of every kind and description, real, personal or mixed,
tangible or intangible, whether now owned or hereafter acquired by the Company, wherever located, and grants a security interest therein for the purposes herein expressed, except any Excepted Property and Excludable Property (each as hereinafter
defined) hereinafter expressly excepted from the lien hereof, and including all and singular the following described property, subject in all cases to the rights of the Company under this Indenture:

notice. 
 In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such
notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be delivered to the Trustee, but such delivery shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver. 

  
 -29-

 In case, by reason of the suspension of mail service or by reason of any other cause, it
shall be impossible to give such notice by mail, then such notification as otherwise provided for in Section 1.03(B) or as shall be specified by the Company and satisfactory to the Trustee shall constitute a sufficient notification for every
purpose hereunder. 
 Section 1.05. Form and Contents of Documents Delivered to Trustee. 

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary
that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. 
 Any certificate or opinion of an Officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, advice of, or representations by, counsel, unless such
Officer knows, or in the exercise of reasonable care should know, that the certificate, opinion, advice or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any Opinion of Counsel may be based,
insofar as it relates to factual matters or matters of business judgment, upon a certificate or opinion of, advice, statements or representations by, an Officer or Officers of the Company stating that the information with respect to such factual
matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate, opinion, advice, statements or representations with respect to such matters are erroneous. Any Opinion
of Counsel may be based upon such assumptions, be subject to such qualifications and may be stated in such language as at the time delivered is considered in the jurisdiction whose laws are covered by such opinion to be appropriate and consistent
with standard practice with respect to opinions relating to such matters. In addition, in giving any Opinion of Counsel, counsel may rely upon legal opinions addressed to the Company or such counsel as appropriate and consistent with standard
practice with respect to reliance on legal opinions of other counsel. Without limiting the foregoing, in giving any Opinion of Counsel with respect to matters involving title or lien priority, counsel may rely upon (i) prior opinions or
certificates of counsel for the Company, regardless of to whom such opinions are addressed, and whether delivered by general counsel, special counsel or in-house counsel for the Company provided such counsel has no reason to believe such reliance is
unwarranted, and (ii) title insurance policies, title insurance commitments and reports, record search certificates, abstracts and other similar evidences of matters reflected in public records and of the existence of liens. 

Whenever any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions
or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

 Wherever in this Indenture, in connection with any application, request, certificate,
statement, opinion or other report to the Trustee, it is provided that the Company shall deliver any document as a condition of the granting of such application, or as evidence of the Company’s compliance with any term hereof, it is intended
that the truth and accuracy, at the time of the granting of such application or at the effective date of such request, certificate, statement, opinion or other report (as the case may be), of the facts and opinions stated in such document shall in
such case be conditions precedent to the right of the Company to have such application granted or to the sufficiency of such document. Notwithstanding anything else herein to the contrary, the validity of any action taken or Obligation issued
hereunder based upon any application, request, certificate, statement, opinion or other report shall not be affected by the truth and accuracy of such document or documents. Nothing in the immediately preceding sentence shall, however, limit any
rights or remedies available to the Trustee or the Holders under this Indenture or at law or equity against the Company, any officer thereof or any Person with respect to a false or inaccurate application, request, certificate, statement, opinion or
other report other than any remedy seeking to invalidate the action so taken or Obligation issued. 
 Whenever a clerical,
typographical, inadvertent or unintentional error or omission shall be discovered in any instrument delivered to the Trustee, a new instrument in corrected form, executed as prescribed herein for that originally delivered and which may bear the same
date as the instrument originally delivered, may be substituted therefor with the same force and effect as if the instrument originally delivered had been filed in the corrected form, or in lieu of such substitution an appropriate adjustment may be
made in a like instrument filed with the Trustee after such discovery. To the extent that action has been taken hereunder which could not have been taken if the original instrument had been filed in the corrected form, such action shall be validated
and rendered effective if the substituted or adjusting instrument shall indicate that any deficiency has been fully satisfied since the delivery of the original instrument. 
 Section 1.06. Compliance Certificates and Opinions. 
 Upon any
application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall furnish to the Trustee an Officers’ Certificate stating that all conditions precedent, if any, provided for in this
Indenture relating to the proposed action have been complied with and, if requested by the Trustee, an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, except that in the
case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or opinion need be
furnished. 
 Every certificate or opinion with respect to compliance with a condition or covenant provided for in this
Indenture (other than statements provided pursuant to Section 14.12 hereof) shall include 
 A. a statement that each
individual signing such certificate or opinion has read such condition or covenant and the definitions herein relating thereto;

 Section 1.17. Investment of Cash Held by Trustee. 

Any cash held by the Trustee or any Paying Agent under any provision of this Indenture shall, except as otherwise provided in Article VIII
and Section 9.07, at the request of the Company evidenced by a Company Request be invested or reinvested as designated by the Company, and, unless an Event of Default shall exist, any interest or other earnings on such investments shall be paid
over promptly to the Company as received by the Trustee, free and clear of any lien, including the lien of this Indenture. Such investments shall be held subject to the same provisions hereof as was the cash used to purchase the same, but at the
request of the Company evidenced by a Company Request shall be sold, in whole or in designated part, and the proceeds of such sale shall be held subject to the same provisions hereof as was the cash used to purchase the investments so sold. If such
sale shall produce a net sum less than the cost of the investments so sold, the Company shall pay promptly to the Trustee or any such Paying Agent, as the case may be, such amount in cash as, together with the net proceeds from such sale, shall
equal the cost of the investments so sold, and if such sale shall produce a net sum greater than the cost of the investments so sold, the Trustee or any such Paying Agent, as the case may be, shall pay over promptly to the Company an amount in cash
equal to such excess, free and clear of any lien, including the lien of this Indenture, unless an Event of Default shall exist. Except as otherwise required by the TIA, the Trustee shall have no liability for losses on investments made at the
request of the Company. 
 Section 1.18. Principal Amount of Certain Obligations. 

A. At any point in time, the principal amount of an Obligation in any form other than a bond shall not include any amount not advanced and
then outstanding thereunder. The principal amount of any Obligation evidencing an assumption by the Company of all or a part of another obligation shall be the principal amount outstanding under such other obligation, or the portion thereof assumed
pursuant to or evidenced by such Obligation. The principal amount of an Obligation in any form other than a bond shall be reduced as the principal amount of such an Obligation (or the obligation it evidences an assumption of) is paid or otherwise
reduced. To the extent permissible under the terms of a specific Obligation, the Company retains the right to have such principal payments or reductions readvanced unless the Company elects to have such payments treated as principal payments or
retirements for purposes of Sections 5.03, 5.06, 5.08, 6.02, 7.03 or 17.03. If any such principal payment or reduction shall not be treated as a payment or retirement because the Company has the right to have such paid or reduced amounts readvanced,
once the readvance right expires or is relinquished or otherwise terminated, such principal payment or reduction shall thereupon be treated as a principal payment or retirement under such Sections. The principal amount of an Obligation in any form
other than a bond may be evidenced from time to time by an Officers’ Certificate delivered to the Trustee and the Holder of such Obligation. In the event the Holder objects to the principal amount of such Obligation as set forth in such
Officers’ Certificate by delivering a written objection to the Trustee within 60 days of the Holder’s receipt of such Officers’ Certificate, the Trustee, at the written direction of such Holder, may require other evidence of the
principal amount of such Obligation. In the absence of any such objection by the Holder, the Trustee may rely conclusively on such Officers’ Certificate. Such Officers’ Certificate shall contain a statement of the foregoing objection
rights of the Holder and the 60-day period for objection.

 B. The principal amount of an Original Issue Discount Obligation shall be determined as
provided in Section 9.22.

 ARTICLE III 
 THE OBLIGATIONS 
 Section 3.01. General Title; General Limitations;
Issuable in Series. 
 Unless specified otherwise by a Company Request or provided for in a Supplemental Indenture, the
general title of all series of Obligations shall be “First Mortgage Obligations,” “First Mortgage Notes” or “First Mortgage Bonds.” 
 The aggregate principal amount of Obligations which may be authenticated and delivered and Outstanding under this Indenture is not limited, except as provided in Article V and the provisions of any
Supplemental Indenture creating any series of Obligations and except as may be limited by law. 
 The Obligations may be issued
in one or more series as from time to time authorized by the Board of Directors. 
 With respect to the Obligations of any
particular series, the Company may incorporate in or add to the general title of such Obligations any words, letters or figures designed to distinguish that series. 
 Section 3.02. Terms of Particular Series. 
 Each series of Additional
Obligations shall be created by a Supplemental Indenture authorized by the Board of Directors and establishing the terms and provisions of such series of Additional Obligations or the method by which such terms and provisions shall be established.
The several series of Additional Obligations may differ as between series in any respect not in conflict with the provisions of this Indenture and as may be prescribed in the Supplemental Indenture creating such series. 

The Company may, at the time of the creation of any series of Obligations or at any time thereafter, make, and the Obligations of such
series may contain, provision for: 
 A. the timing and amount of principal and interest payments due on such series;

 B. the exchange or conversion of the Additional Obligations of such series, at the option of the Holders thereof, for or into
new Additional Obligations of a different series or other securities; 
 C. a sinking, amortization, improvement or other
analogous fund; 
 D. limiting the aggregate principal amount of the Additional Obligations of such series; 

E. exchanging Additional Obligations of such series, at the option of the Holders thereof, for other Obligations of the same series of
the same aggregate principal amount of a different authorized kind or authorized denomination or denominations; 

  
 -36-

 F. the authentication of Additional Obligations of such series by the Authenticating Agent;

 G. the issuance of Additional Obligations of such series in bearer or book-entry form; 

H. specifying redemption or prepayment terms and procedures with respect to such series; 

I. specifying business days, grace periods, record dates, other provisions and such covenants, events of default or remedies with respect
to Additional Obligations of such series; and 
 J. any other terms of the Additional Obligations of such series, or any
maturity thereof, not inconsistent with the provisions of this Indenture; 
 all upon such terms as the Board of Directors may determine as
evidenced by a Board Resolution. 
 All Additional Obligations of like maturity of the same series shall be substantially
identical except that any series may have serial maturities and different interest rates for different maturities and except that the Supplemental Indenture creating such series may provide that Additional Obligations of like maturity of such series
need not be identical as to interest rates and terms of redemption. 
 With respect to Additional Obligations of a series
subject to a Periodic Offering, the Supplemental Indenture or the Board Resolution, or Officers’ Certificate pursuant to the Supplemental Indenture or Board Resolution, as the case may be, which establishes such series may provide general terms
or parameters for Additional Obligations of such series and specify procedures by which such specific terms are to be established (which procedures may provide for authentication and delivery pursuant to oral or electronic instructions from the
Company or any agent or agents thereof, which oral instructions are to be promptly confirmed electronically or in writing). 

Section 3.03. Form and Denominations. 
 The form of the Additional Obligations of each series shall be established by the provisions of this Indenture creating such series. The Obligations of each series shall be distinguished from the
Obligations of other series in such manner as may be determined by the Officers of the Company executing particular Obligations as evidenced by their execution thereof. The provisions of the Indenture creating a series of Obligations may designate
whether the Obligations will be held in the Book-Entry System. 
 The Obligations of each series shall be issuable in such
denominations as shall be provided in the provisions of the Indenture creating such series. In the absence of any such provision with respect to the Obligations of any particular series, the Obligations of such series shall be in the denomination of

 Section 3.04. Execution, Authentication, Delivery and Dating. 

The Obligations shall be executed on behalf of the Company by its President or one of its Vice Presidents, its Secretary or Treasurer, or
such other Officer who may be designated by a Board Resolution to execute the Obligations, and, if required by a Board Resolution, attested by its Secretary or one of its Assistant Secretaries. The signature of any of these Officers on the
Obligations may be manual or facsimile. Obligations bearing the manual or facsimile signatures of individuals who were at any time the proper Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them shall
have ceased to hold such offices prior to the authentication and delivery of such Obligations or shall not have held such offices at the date of such Obligations. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Obligations executed by the Company to the Trustee for authentication, together with a Company
Order for the authentication and delivery of such Obligations, and the Trustee shall authenticate and deliver such Obligations as in this Indenture provided and not otherwise. 
 All Obligations shall be dated as provided in the Supplemental Indenture creating such Obligations or, in the absence thereof, the date of their authentication. 

No Obligation shall be secured by, or be entitled to any lien, right or benefit under, this Indenture or be valid or obligatory for any
purpose, unless there appears on such Obligation (or an allonge thereto) a certificate of authentication substantially in the form provided for herein, executed by the Trustee or the Authenticating Agent by manual signature, and such certificate
upon any Obligation (or an allonge thereto) shall be conclusive evidence, and the only evidence, that such Obligation has been duly authenticated and delivered hereunder. 
 Section 3.05. Temporary Obligations. 
 Pending the preparation of
definitive Obligations, the Company may execute, and upon Company Request the Trustee shall authenticate and deliver, temporary Obligations which are printed, lithographed, typewritten, photocopied or otherwise produced or reproduced, in any
authorized denomination, substantially of the tenor of the definitive Obligations in lieu of which they are issued, and with such appropriate insertions, omissions, substitutions and other variations as the Officers executing such Obligations may
determine, as evidenced by their execution of such Obligations. 
 If temporary Obligations are issued, the Company will cause
definitive Obligations to be prepared without unreasonable delay. After the preparation of definitive Obligations, the temporary Obligations shall be exchangeable for definitive Obligations upon surrender of the temporary Obligations at the office
or agency of the Trustee in a Place of Payment therefor, without charge to the Holder. Upon surrender for exchange of any one or more temporary Obligations the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor
a like principal amount of definitive Obligations of authorized denominations. Until so exchanged, temporary Outstanding Secured Obligations shall in all respects be entitled to the security and benefits of this Indenture. Upon surrender for
exchange, temporary Obligations shall be canceled as provided in Section 3.10. 

  
 -38-

 Section 3.06. Registration; Registration of Transfer and Exchange. 

The Company shall cause to be kept at one of the offices or agencies maintained by the Trustee as provided in Section 14.02 a
register (herein sometimes referred to as the “Obligation Register”) in which, subject to such reasonable regulations as it may prescribe, the Trustee shall provide for the registration of Obligations and registration of transfers
of Obligations. The Trustee is hereby appointed “Obligation Registrar” for the purpose of registering Obligations and transfers of Obligations as herein provided. 

Upon surrender for registration of transfer of any Obligation at the office or agency of the Trustee (or the delivery of other evidence
satisfactory to the Trustee of the transfer of an Obligation), the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Obligations of the same series and
maturity, of any authorized denomination and of a like aggregate principal amount (in the event such Obligation is not surrendered for transfer, upon delivery to the Trustee of such reasonably satisfactory evidence of a transfer, the Obligation
Registrar shall register such transfer on the Obligations Register). 
 Upon surrender for exchange of any Obligation at the
office or agency of the Trustee, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the Holder exchanging such Obligation, one or more new Obligations of the same or, in connection with the exchange of one
series of Obligations for another as provided in a Supplemental Indenture, a different series, in each case, in an authorized denomination and of a like aggregate principal amount and maturity. 

All Obligations surrendered upon registration of any exchange or transfer provided for in this Indenture shall be promptly cancelled by
the Trustee and thereafter the Trustee shall retain such Obligations or destroy such Obligations and deliver a certificate of destruction to the Company. 
 All Obligations issued upon any registration of transfer or exchange of Obligations shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same security and benefits
under this Indenture, as the Obligations surrendered upon such registration of transfer or exchange. 
 Every Obligation
presented or surrendered for registration of transfer, exchange or discharge from registration shall (if so required by the Company or the Obligation Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Obligation Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. 
 No service charge shall be made for any registration, discharge from registration, registration of transfer or exchange of Obligations, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Obligations, other than exchanges under Section 3.05, 13.06 or 15.07 not involving any transfer. 

  
 -39-

 Except as provided in a Supplemental Indenture, the Company shall not be required
(1) to issue, register the transfer or exchange of any Obligation of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Obligations of such series under
Section 15.04 and ending at the close of business on the day of such mailing, or (2) to register the transfer or exchange of any Obligation so selected for redemption in whole or in part, except the unredeemed portion of an Obligation
being redeemed in part. 
 Section 3.07. Mutilated, Destroyed, Lost and Stolen Obligations. 

If (1) any mutilated Obligation is surrendered to the Trustee, or the Company and the Trustee receive evidence to their satisfaction
of the destruction, loss or theft of any Obligation, and (2) there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company or
the Trustee that such Obligation has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Obligation, a new Obligation of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Obligation has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Obligation, pay all amounts
to become due and payable with respect to such Obligation. 
 Upon the issuance of any new Obligation under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expense (including the fees and expenses of the Trustee) connected therewith. 

Every new Obligation issued pursuant to this Section in lieu of any destroyed, lost or stolen Obligation shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Obligation shall be at any time enforceable by anyone, and shall be entitled to all the security and benefits of this Indenture equally and ratably with
all other Outstanding Secured Obligations. 
 The provisions of this Section are exclusive and shall preclude (to the extent
lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Obligations. 
 Section 3.08. Payment of Interest; Interest Rights Preserved. 

Interest on any Obligation of any series which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Obligation (or one or more Predecessor Obligations) is registered at the close of business on the Regular Record Date for such interest as specified herein or in the provisions of the Supplemental Indenture
creating such series. 

  
 -40-

 Any interest on any Obligation of any series which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall be payable as provided in such Obligation, or if not so provided, shall forthwith cease to be payable to the Holder on the relevant Regular
Record Date solely by virtue of such Holder having been such Holder, and such Defaulted Interest may be paid by the Company, at its election, as provided in Subsection (A) or (B) below: 

A. The Company may elect to make payment of any Defaulted Interest on the Obligations of any series to the Persons in whose names such
Obligations (or their respective Predecessor Obligations) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee
in writing of the amount of Defaulted Interest proposed to be paid on each Obligation and the date of the proposed payment (which date shall be such as will enable the Trustee to comply with the next sentence hereof), and at the same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the
proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Subsection provided and not to be deemed part of the Trust Estate or Trust Moneys. Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days nor less than ten days prior to the date of the proposed payment and not less than ten days after the receipt by the Trustee of the
notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor to be mailed, first-class postage prepaid, to each Holder of an Obligation of such series at his address as it appears in the Obligation Register not less than ten days prior to such Special Record Date. Notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Obligations of such series (or their respective Predecessor Obligations)
are registered on such Special Record Date and shall no longer be payable pursuant to the following Subsection (B). 
 B. The
Company may make payment of any Defaulted Interest on the Obligations of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Obligations may be listed and upon such notice as may be
required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Subsection, such payment shall be deemed practicable by the Trustee. 

Subject to the foregoing provisions of this Section 3.08, each Obligation delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Obligation shall carry all the rights to interest accrued and unpaid, and to accrue, which were carried by such other Obligation and each such Obligation shall bear interest from the date
specified in the delivered Obligation, so that neither gain nor loss in interest shall result from such transfer, exchange or substitution. 

  
 -41-

 Section 3.09. Persons Deemed Owners. 

Subject to the provisions of Section 1.13, prior to due presentment of such Obligation for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Obligation is registered in the Obligation Register as the Holder of such Obligation for the purpose of receiving payment of principal of (and premium, if
any) and (subject to Section 3.08) interest on such Obligation and for all other purposes whatsoever, whether or not such Obligation be overdue, and, to the extent permitted by law, neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary. 
 Section 3.10. Cancellation. 

All Obligations surrendered for payment, redemption, transfer, reissue, exchange or conversion, if surrendered to the Trustee, shall be
promptly cancelled by it, and, if surrendered to any Person other than the Trustee, shall be delivered to the Trustee and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Obligations previously authenticated and delivered hereunder, which the Company may have acquired in any manner whatsoever, and all Obligations so delivered shall be promptly cancelled by the Trustee. No Obligation shall be
authenticated in lieu of or in exchange for any Obligation cancelled as provided in this Section, except as expressly provided by this Indenture. All cancelled Obligations shall be retained and destroyed (if applicable) by the Trustee in accordance
with its document retention policies and, if the cancelled Obligations are destroyed, the Trustee thereafter shall deliver a certificate of destruction to the Company. 
 ARTICLE IV 
 PRE-EXISTING OBLIGATIONS 

Section 4.01. Effect of Amendment and Restatement; Terms. 

Pre-Existing Obligations Outstanding immediately prior to the date hereof shall remain Outstanding under this Indenture following its
amendment and restatement, without the need for further authentication by the Trustee or other action. The form, designation and terms of each such Pre-Existing Obligation shall be established in the applicable Supplemental Indenture establishing
such Pre-Existing Obligation, regardless of whether such Supplemental Indenture was executed before the date of this Indenture.

 -43-

 
Additional Obligations are established), will be the legal, valid and binding obligations of the Company enforceable in accordance with their terms and the terms of this Indenture (subject to
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles) and entitled to the benefits of and secured by the lien

 In the

Additional Obligations authenticated and delivered under this Article, the Company may surrender such Additional Obligations to the Trustee, whereupon such Additional Obligations, if not previously canceled, shall be canceled by the Trustee. The
Additional Obligations so surrendered shall thereafter be treated as though they had never been Outstanding. In addition, in the event that any portion of an Additional Obligation or series of Additional Obligations shall not be advanced or issued,
and the Company’s right to receive and advance or issue such portion terminated as evidenced by an Officer’s Certificate delivered to the Trustee, such portion shall thereafter be treated as though it had never been Outstanding and the
basis for issuing such Additional Obligations shall be deemed never to have been used for such purpose.

time to time be executed by the Company and delivered to the Trustee for authentication, and the same shall be authenticated and delivered by the Trustee upon Company Order, in an aggregate principal amount up to but not exceeding the product

Additions, which may include Property Additions to be acquired in connection with the granting of the related Application which shall be considered as already acquired for the purpose of computing the Amount of Property Additions. The Certificate
shall state that none of such Property Additions has been described in any previous Certificate as to Bondable Additions (except Property Additions described in any previous Certificate as to Bondable Additions and used as the basis for the
authentication and delivery of Additional Obligations surrendered to the Trustee pursuant to the last paragraph of Section 5.01 or as the basis for any principal amount of an Additional Obligation or series of Additional Obligations which has
not been loaned or advanced or an Additional Obligation or series of Additional Obligations which has not been issued and for which the Company’s right to receive a loan or advance under or to issue such Obligation has been terminated as
provided in the last paragraph of Section 5.01). Except for major individual items, such Property Additions may be grouped by major classifications then being used by the Company in the maintenance of its fixed plant accounts and may, in the
case of tracts or parcels of land or easements or rights-of-way, be described by reference to the deeds through which they were acquired or to the Supplemental Indenture conveying them to the Trustee. The Certificate shall specify and separately
describe any Property Additions consisting of a major item or an Acquired Facility or Property Additions acquired and paid for in whole or in part through the transfer or delivery of securities or other property, together with a description of the
kind and respective amounts of such securities or other property. The Cost to the Company shall be shown separately for each of such Property Additions which is separately described, whether described as a major item or as an Acquired Facility or as
Property Additions acquired and paid for in whole or in part through the transfer or delivery of securities or other property. The Cost to the Company may be shown in the aggregate for all Property Additions grouped within each particular major
classification and the Cost to the Company may be allocated among major items and major classifications by an estimate of such nature and upon such basis as the signers deem proper. 

(b) The Certificate shall also state the Fair Value to the Company, in the opinion of the Engineer or Appraiser signing
such Certificate, of such Property Additions, separately for each thereof or group thereof for which Cost to the Company is shown separately in the Certificate; PROVIDED, HOWEVER, that if such Property Additions include an Acquired
Facility, the Fair Value to the Company thereof shall be stated as being the amount thereof set forth in any Independent Engineer’s or Independent Appraiser’s Certificate required by Subsection (C) of this Section 5.02. In
addition the Certificate shall also state the fair market value in cash, as stated in any Independent Appraiser’s Certificate required by Subsection (D) of this Section 5.02, of any securities or other property transferred or
delivered to acquire or pay for any such Property Additions. 

  
 -46-

 (c) The Certificate shall state that, with respect to each of such Property
Additions or group thereof for which Cost to the Company is shown separately or by groups in the Certificate, the certified Amount of Property Additions is the lower of the certified Cost to the Company thereof and the certified Fair Value to the
Company thereof. 
 (d) Nothing in this Section shall be deemed to prevent the Company from certifying any
Property Additions acquired by the Company during any period without simultaneously certifying other Property Additions that the Company may have acquired in that or any other period, and by so doing the Company shall not be deemed to have lost the
right so to certify later such other Property Additions. 
 (3) The aggregate amount (item 3 in Summary) of all
Retirements during the period from the date to which Retirements had been included in item 3 of the most recent Summary theretofore delivered to the Trustee (or the Cut-Off Date in the case of the first such Certificate) to the later of (a) a
date not earlier than the 90th day before the date of the related Application and (b) the end of the period specified in the current Certificate pursuant to clause (2) above. 

(4) The credits (item 4 in Summary) against Retirements, which shall equal, subject to the provisions of the last sentence
of clause (5) below, the sum of the following:

forward from the most recent Certificate, as provided in the last sentence of clause (5) below; 
 (b) the
aggregate amount of (i) any cash, (ii) purchase money obligations, (iii) the principal amount of retired Obligations or principal amounts paid on Obligations (which amount may not be reloaned or readvanced under such Obligations),
(iv) Bondable Additions and (v) Designated Qualifying Securities, in each case, delivered or certified to the Trustee for use as a basis for release of any part of the Trust Estate under Section 6.02 during the period covered by
clause (3) above; and 
 (c) all insurance moneys received by the Trustee pursuant hereto or paid to a
trustee, mortgagee or other holder under a Prior Lien during the period covered by clause (3) above on account of the damage, loss or destruction of any Bondable Property. 

(5) The excess (item 6(a) in Summary) of the Amount of Property Additions shown pursuant to clause (2) above (item 2
in Summary) over the net amount of Retirements (item 5 in Summary), which net amount shall be determined by deducting the credits shown pursuant to clause (4) above (item 4 in Summary) from the aggregate amount of Retirements shown pursuant to
clause (3) above (item 3 in Summary), and such excess shall be the amount of the net Bondable Additions then being certified. If in any case the credits against Retirements exceed the aggregate amount of Retirements

  
 -47-

 
shown pursuant to clause (3) above (item 3 in Summary), the net amount of Retirements for the purpose of this clause shall be deemed to be zero, but such excess of credits against
Retirements may be carried forward and used as a credit against Retirements in the next Certificate. 
 (6) (a)
The sum (item 6(b) in Summary) of the amount shown pursuant to clause (1) above (item 1 in Summary) and the amount shown pursuant to clause (5) above (item 6(a) in Summary), namely the total Bondable Additions then available.

combination) (i) 110% of the aggregate principal amount of any Additional Obligations whose authentication and delivery are then being applied for under this Section, (ii) 110% of the aggregate principal amount of the loans or other
advances under Conditional Obligations which are then being applied for under Section 5.06, (iii) 110% of the amount of any Deposited Cash which is then being withdrawn under Section 5.08, (iv) 100% of any Trust Moneys which are
then being withdrawn under Section 7.02, (v) 100% of any Bondable Additions which are then being used as a basis for a release under Section 6.02, (vi) 110% of the aggregate principal amount of Designated Qualifying Securities
then being redesignated or surrendered under Section 17.3, and (vii) 110% of the outstanding principal amount then being converted under Section 5.10. 

(7) The balance (item 8 in Summary) of the Bondable Additions shown by the Certificate that will remain after the granting
of the Application then being made, which shall be computed by deducting the sum shown pursuant to clause 6(b) above (item 8 in Summary) from the amount shown pursuant to clause 6(a) above (item 7 in Summary). 

(8) Except when converting outstanding principal amounts under Section 5.10, if any of the Property Additions
described in the Certificate were acquired with Certified Progress Payments: 
 (a) the amount of such Property
Additions acquired with Certified Progress Payments; and 
 (b) the aggregate principal amount of the Additional
Obligations authenticated and delivered upon the basis of the Certified Progress Payments used to acquire the Property Additions certified pursuant to clause 8(a) above that has been paid, redeemed or otherwise retired or defeased under Article
VIII, which shall equal the product obtained by multiplying a fraction, the numerator of which is 100 and the denominator of which is 110 by the amount of Property Additions certified pursuant to clause (a) above. 

(9) That the Property Additions described in the Certificate have not previously been certified for use as the basis for
converting outstanding principal amounts under Section 5.10. 

  
 -48-

 (10) That the Property Additions described in the Certificate, except such
as have been Retired, are desirable in the conduct of the business of the Company; that the allocation of the Cost to the Company of such Property Additions to each major item or major classification thereof is, in the opinion of the signers,
proper; and that the balance of the Bondable Additions to remain after the action applied for plus the Cost to the Company or the Fair Value to the Company, whichever is less, of uncertified Property Additions is at least equal to the aggregate
amount of uncertified Retirements. 
 (11) That the allowances or charges, if any, for interest, taxes,
engineering, legal and accounting costs and expenses, allocated administrative charges, superintendence fees and expenses, insurance, casualties and other expenses during construction (or in connection with the acquisition of Property Additions)
which are included in the Cost to the Company of such of the Property Additions described in the Certificate as were constructed or acquired by or for the Company have been charged and are properly chargeable to fixed plant accounts in accordance
with Accounting Requirements and are, in the opinion of the signers, proper in respect of the Property Additions specified. 
 (12) That no portion of the Cost to the Company of the Property Additions described in the Certificate should properly have been charged to maintenance or repairs and that no expenditures are included in
the Certificate which under Accounting Requirements are not properly chargeable to fixed plant accounts.

 Conditional Obligations are (i) Additional Obligations authenticated and delivered as provided in this Section, and under which no principal amount is outstanding thereunder at the time of such
authentication and delivery and (ii) Existing Obligations with principal amounts remaining to be loaned or advanced after the date hereof. 
 Conditional Obligations of one or more new series, or Conditional Obligations of an existing series, may from time to time be executed by the Company and delivered to the Trustee for authentication, and
thereupon such Conditional Obligations shall be authenticated and delivered by the Trustee upon Company Request, upon receipt by the Trustee of the documents and cash deposit, if any, specified in Subsections (A), (B), (C) and (D) of

Loans or advances under a Conditional Obligation shall only be made upon the delivery of a written certification by the Trustee under

Conditional Obligations on the same basis. Upon Company Request specifying the amount of the loan or advance being requested and showing the total amount available to be drawn under the applicable Conditional Obligation, the Trustee shall deliver to

(in each case with such omissions and variations as are appropriate in view of the fact that such Sections are being used as the basis for loans or advances under Conditional Obligations rather than the authentication and delivery of Additional
Obligations), which documents would permit the authentication and delivery of Additional Obligations in an aggregate principal amount equal to such requested loan or advance.

 B. An Available Margins Certificate. 

C. An Officers’ Certificate and an Opinion of Counsel each stating that the conditions precedent provided for in this Indenture for
the Trustee to deliver a written certificate with respect to such loan or advance have been complied with.

vendor’s, mechanics’, laborers’, materialmen’s, statutory or other similar lien upon any of such repairs, rebuildings or replacements, which lien might, in the opinion of the signers of such Certificate, materially impair the
security afforded by such repairs, rebuildings or replacements;

 (3) the Company has paid or caused to be paid all sums then due from the
Company hereunder and under the Obligations; 
 (4) the Company has delivered an Opinion of Counsel from a
nationally recognized law firm stating that the Holders of such Obligations (or the Trustee for the benefit of such Holders) shall have a perfected security interest under applicable law in the money or Defeasance Securities so deposited; and

 (5) the Company has delivered to the Trustee and any Paying Agent an Officers’ Certificate and an Opinion
of Counsel, each stating that the conditions set forth in paragraphs (1) through (3) above have been complied with. 
 After any such
irrevocable deposit, the Trustee upon Company Request shall acknowledge in writing the discharge of the Company’s obligations under such Obligations and of the Company’s obligations to or for the benefit of the Holders of such Obligations
under this Indenture, except for those surviving obligations specified below. 
 C. Notwithstanding the satisfaction of the
conditions set forth in Subsection (B) with respect to any Obligations, the Company’s and the Trustee’s obligations to or for the Holders of such Obligations or to the Trustee under Sections 3.06, 3.07, 8.02, 8.03, 8.04, 10.07, 10.10,
11.02, 14.01, 14.02, 14.03 and 16.14 shall survive until such Obligations are no longer Outstanding. Thereafter, only the Company’s obligations under Sections 8.03, 8.04, 10.07 and 16.14 shall survive with respect to such Holders or the
Trustee. 
 D. The Trustee or Paying Agent shall, if so directed by the Company (i) prior to the Stated Maturity of
Obligations in respect of which a deposit has been made under Subsection (B)(1) above which are not to be redeemed prior to their Stated Maturity or (ii) prior to the giving of the notice of redemption referred to in Subsection (B)(1)
above with respect to any Obligations in respect of which a deposit has been made under Subsection (B)(1) which are to be redeemed on a date prior to their Stated Maturity, apply moneys deposited with the Trustee in respect of such Obligations and
redeem or sell Defeasance Securities so deposited with the Trustee and apply the proceeds thereof to the purchase of such Obligations and the Trustee shall immediately thereafter cancel all such Obligations so purchased; PROVIDED,
HOWEVER, that the Trustee shall have received a certificate of a nationally recognized firm of Independent Accountants certifying, and setting forth calculations demonstrating, that the moneys and Defeasance Securities remaining on deposit with
the Trustee or Paying Agent after the purchase and cancellation of such Obligations shall be sufficient to pay when due the principal or Redemption Price (if applicable) of, and interest due or to become due on, all Obligations in respect of which
such moneys and Defeasance Securities are being held by the Trustee or Paying Agent on or prior to the Redemption Date or Stated Maturity thereof, as the case may be. In the event that on any date as a result of any purchases and cancellations of
Obligations as provided in this Subsection the total amount of moneys and Defeasance Securities remaining on deposit with the Trustee or Paying Agent under this Section is in excess of the total amount that would have been required to be deposited
with the Trustee or Paying Agent on such date under 

  
 -82-

 
Subsection (B)(1) in respect of the remaining Obligations for which such moneys and Defeasance Securities are being held, the Trustee or Paying Agent shall, if requested by the Company and upon
receipt by the Trustee or Paying Agent of a certificate of a nationally recognized firm of Independent Accountants setting forth the calculation of such excess, pay the amount of such excess to the Company free and clear of any trust, lien, security
interest, pledge or assignment securing such Obligations or otherwise existing under this Indenture. 
 E. If the requirements
of this Section 8.01 have been satisfied with respect to all Obligations theretofore Outstanding, then, upon Company Request, the rights and interest created hereby shall become null and void and be cancelled and surrendered (except as
otherwise provided herein) and the Trustee and each co-trustee and separate trustee, if any, then acting as such hereunder shall, at the expense of the Company, execute and deliver a termination statement and such instruments of satisfaction and
discharge as may be necessary and pay, sign, transfer and deliver to the Company or upon Company Order all cash, securities and other property then held by it hereunder as part of the Trust Estate. 

Section 8.02. Application of Deposited Money and Money From Defeasance Securities. 

Money or Defeasance Securities deposited with the Trustee or the Paying Agent pursuant to Section 8.01 shall not be part of the Trust
Estate and shall not be deemed to be Trust Moneys but shall constitute a separate trust fund for the benefit of persons entitled thereto. Subject to the provisions of Section 14.03, the Trustee or Paying Agent shall hold in trust money or
Defeasance Securities deposited with it pursuant to Section 8.01, and shall apply the deposited money and the money from Defeasance Securities to the payment of the principal or Redemption Price (if applicable) of, and interest on, the
Obligations in respect of which such money and Defeasance Securities are deposited. If money deposited with the Trustee under this Article VIII, or money received from principal or interest payments on Defeasance Securities deposited with the
Trustee under this Article VIII, will be required at a later date for payment of the principal or Redemption Price (if applicable) of, and interest on, the Obligations in respect of which such money and Defeasance Securities are deposited, such
money shall, at the written investment direction of the Company, to the extent practicable, be reinvested in Defeasance Securities maturing at times and in amounts that, together with other moneys so deposited or to be generated by other Defeasance
Securities, will be sufficient to pay when due the principal or Redemption Price (if applicable) of, and interest to become due on, such Obligations, and the interest earned from such reinvestments shall be paid over to the Company, as received by
the Trustee, free and clear of any trust, lien, security interest, pledge or assignment securing said Obligations or otherwise existing under this Indenture. 
 Section 8.03. Repayment to Company. 
 Subject to Section 8.01, to
the extent any Defeasance Securities deposited with the Trustee or Paying Agent under this Article VIII, or cash received from principal or interest payments on such Defeasance Securities, will not be required for the payment of the principal or
Redemption Price (if applicable) of, and interest on, the Obligations in respect of which such money and Defeasance Securities are deposited, the Trustee and the Paying Agent shall upon Company Request, accompanied by a certificate of a nationally
recognized firm of Independent 

  
 -83-

 
Accountants calculating such excess, promptly pay and deliver to the Company upon Company Request any such Defeasance Securities and cash, and thereupon the Trustee or Paying Agent shall be
relieved from any liability with respect thereto. Without limiting the foregoing, the Trustee and the Paying Agent shall pay to the Company upon Company Request any money held by them for the payment of principal, Redemption Price or interest that
remains unclaimed for two years after the date such payment was due. After payment to the Company, Holders entitled to such money must look to the Company for payment as general creditors unless an applicable law designates another person, and all
liability of the Trustee and such Paying Agent with respect to such money shall cease. 
 Section 8.04. Reinstatement.

 If the Trustee or Paying Agent is unable to apply any money or Defeasance Securities in accordance with Section 8.01
and the second sentence of Section 8.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, (i) the Company’s
obligations under this Indenture to or for the benefit of the Holders of Obligations for whose benefit such money or Defeasance Securities were deposited (other than obligations arising under any provisions creating the lien hereof) and under such
Obligations shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or Paying Agent is permitted to apply all such money and Defeasance Securities in accordance with
Section 8.01, and (ii) the lien of this Indenture shall be reinstated for the benefit of such Holders (and, if the lien of this Indenture shall previously have been fully released, then to the extent possible, the Company shall take all
actions required to subject assets of the Company to a lien substantially similar, in amount and otherwise, to the Trust Estate subject to the lien of this Indenture as in effect on the date of the termination of the Company’s obligations
hereunder pursuant to Section 8.01, which lien shall be effective until such time as the Trustee or Paying Agent is permitted to apply all such money and Defeasance Securities in accordance with Section 8.01); PROVIDED,
HOWEVER, that if the Company has made any payment of interest on or principal of any Obligations because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Obligations to receive such
payment from the money or Defeasance Securities held therefor by the Trustee or Paying Agent. Notwithstanding the foregoing or any other provision of this Indenture, during any period in which the Trustee or Paying Agent is unable, for any of the
reasons described in the first sentence of this Section, to apply in accordance with Section 8.01 and the second sentence of Section 8.02 for the benefit of the Holders of any Obligations any money or proceeds from Defeasance Securities
deposited with the Trustee with respect to such Obligations pursuant to Section 8.01, the Company’s right to obtain any excess funds from such moneys or proceeds, and the Company’s subrogation rights arising hereunder with respect to
such Obligations, shall be suspended.

 EVENTS OF DEFAULT AND REMEDIES 
 Section 9.01. Events of Default.

 “Event of Default,” wherever used herein, means any one of the following events (whatever the reason for
such event and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 

A. default in the payment of any interest upon any Obligation when such interest becomes due and payable, and continuance of such default
for a period of five business days or such other period as may be provided for in such Obligation or in the Supplemental Indenture under which such Obligation is issued; or 
 B. default in the payment of the principal of (or premium, if any, on) any Obligation at its Maturity and, if there is a grace period provided for in such Obligation or the Supplemental Indenture under

Obligations, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder, unless such default cannot be reasonably cured within such 45-day period then,
so long as a cure is being diligently pursued, the Company shall have a reasonable period of time beyond such 45-day period to complete such cure, but in no event shall such period of time exceed 180 days without the consent of the Holders of not
less than 20% in principal amount of the Obligations Outstanding at the end of the 180-day period; or 
 D. a failure to pay any
portion of the principal when due and payable (other than amounts due and payable on acceleration) under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company, other than any indebtedness evidenced by an
Obligation, whether such indebtedness now exists or shall hereafter be created, which failure shall have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and
payable in an aggregate principal amount exceeding $25,000,000 without such indebtedness having been discharged or such acceleration having been rescinded or annulled within a period of ten days after such acceleration; or 

E. the rendering against the Company of a judgment for the payment of moneys in excess of the sum of $25,000,000 and the continuance of

 -85-

 
of execution thereon entered within such first mentioned 45 days; but only in either case if such judgment shall have been continued unstayed or unsatisfied for a period of ten days after written
notice of default hereunder shall have been given, by registered or certified mail, to the Company by the Trustee, or to the Company and the Trustee by the Holders of not less than 20% in principal amount of the Obligations Outstanding; or

 F. the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the
Company in an involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company to be bankrupt or insolvent, or approving as properly
filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other
similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief of any such other decree or order unstayed and in effect
for a period of 60 consecutive days; or

the Company in an involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by
it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or state law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator,
assignee, trustee, sequestrator or similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts
generally as they become due, or the taking of corporate action by the Company in furtherance of any such action. 

Section 9.02. Acceleration of Maturity Rescission and Annulment. 

If an Event of Default exists, then and in every such case the Trustee or the Holders of not less than 25% in principal amount of the
Obligations Outstanding may declare the principal (or, if the Obligations of any series are Original Issue Discount Obligations, such portion of the principal amount of such Original Issue Discount Obligations as may be specified in the terms of
such series) of all the Obligations to be due and payable immediately, by a notice in writing to the Company (and to the Trustee, if given by Holders), and upon any such declaration such principal shall become immediately due and payable.

 At any time after such a declaration of acceleration has been made, but before any sale of any of the Trust Estate has been
made under this Article or any judgment or decree for payment of money due on any Obligations has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Obligations Outstanding
(unless such declaration has been made under Section 9.23 only with respect to a particular series of Outstanding Obligations, in which event only a majority in principal amount of the Obligations of such series) may, by written notice to the
Company and the Trustee, rescind and annul such declaration and its consequences if 

  
 -86-

 A. the Company has paid or deposited with the Trustee a sum sufficient to pay 

(1) all overdue installments of interest on all Obligations, 

(2) the principal of (and premium, if any, on) any Obligations which have become due otherwise than by such declaration of
acceleration and interest thereon at the rate or rates prescribed therefor in such Obligations, 
 (3) to the
extent that payment of such interest is lawful, interest upon overdue installments of interest at the rate or rates prescribed therefor in such Obligations, and 
 (4) all late payment charges or fees, if any, prescribed in such Obligation, and 
 (5) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and 

B. all Events of Default, other than the non-payment of the principal of Obligations which have become due solely by such declaration of
acceleration, have been cured or have been waived as provided in Section 9.17. 
 No such rescission and annulment shall
affect any subsequent default or impair any right consequent thereon. 
 Section 9.03. Entry. 

The Company agrees that upon the occurrence of an Event of Default the Company, upon demand of the Trustee during the continuance thereof,
shall forthwith surrender to the Trustee the actual possession of, and it shall be lawful for the Trustee by such officers or agents as it may appoint to enter and take possession of, the Trust Estate (and the books, papers and accounts of the
Company), and to hold, operate, manage and control the Trust Estate (including the making of all needful repairs, and such alterations, additions and improvements as the Trustee shall deem wise) and to receive the rents, issues, tolls, profits,
revenues and other income thereof, and, after deducting the costs and expenses of entering, taking possession, holding, operating and managing the Trust Estate, as well as payments for taxes, insurance and other proper charges upon the Trust Estate
and reasonable compensation to itself, its agents and counsel, to apply the same as provided in Section 9.07. Whenever all that is then due upon the Obligations and under any of the terms of this Indenture shall have been paid and all defaults
hereunder shall have been made good, the Trustee shall surrender possession of such property to the Company. 

  
 -87-

 Section 9.04. Power of Sale; Suits for Enforcement. 

In case an Event of Default shall occur and be continuing, the Trustee, with or without entry, in its discretion may, subject to the
provisions of Section 9.16: 
 A. sell, subject to any mandatory requirements of applicable law (including
Section 55.58 et seq. of the Virginia Code), the Trust Estate as an entirety, or in such parcels as the Holders of a majority in principal amount of the Obligations then Outstanding shall in writing request, or in the absence of such
request, as the Trustee may determine, to the highest bidder at public auction and upon such terms as the Trustee may (subject to applicable law) fix; or 
 B. proceed to protect and enforce its rights and the rights of the Holders under this Indenture by sale pursuant to judicial proceedings or by a suit, action or proceeding in equity or at law or
otherwise, whether for the specific performance of any covenant or agreement contained in this Indenture or in aid of the execution of any power granted in this Indenture or for the foreclosure of this Indenture or for the enforcement of any other
legal, equitable or other remedy, as the Trustee, being advised by counsel, shall deem most effectual to protect and enforce any of the rights of the Trustee or the Holders. 
 Section 9.05. Incidents of Sale. 
 Upon any sale of any of the Trust
Estate, whether made under the power of sale hereby given or pursuant to judicial proceedings, to the extent permitted by law: 

A. the principal of and accrued interest on all Outstanding Secured Obligations, if not previously due, shall at once become and be
immediately due and payable; 
 B. any Holder or Holders or the Trustee may bid for and purchase the property offered for sale,
and upon compliance with the terms of sale may hold, retain and possess and dispose of such property, without further accountability, and may, in paying the purchase price therefor, deliver any Outstanding Secured Obligations or claims for interest
thereon in lieu of cash in the amount which shall, upon distribution of the net proceeds of such sale, be payable thereon, and (unless such sale is effected under power of sale) such Obligations, in case the amounts so payable thereon shall be less
than the amount due thereon, shall be returned to the Holders thereof after being appropriately stamped to show partial payment; 
 C. the Trustee may make and deliver to the purchaser or purchasers a good and sufficient deed, bill of sale and instrument of assignment and transfer of the property sold; 

D. the Trustee is hereby irrevocably appointed the true and lawful attorney of the Company, in its name and stead, to make all necessary
deeds, bills of sale and instruments of assignment and transfer of the property thus sold; and for that purpose it may execute all necessary deeds, bills of sale and instruments of assignment and transfer, and may substitute one or more persons,
firms or corporations with like power, the Company hereby ratifying and confirming all that its said attorney or such substitute or substitutes shall lawfully do by virtue hereof; but if so requested by the Trustee or by any purchaser, the Company
shall ratify and confirm any such sale or transfer by executing and delivering to the Trustee or to such purchaser or purchasers all proper deeds, bills of sale, instruments of assignment and transfer and releases as may be designated in any such
request; 

  
 -88-

 E. all right, title, interest, claim and demand whatsoever, either at law or in equity or
otherwise, of the Company of, in and to the property so sold shall be divested and such sale shall be a perpetual bar both at law and in equity against the Company, its successors and assigns, and against any and all persons claiming or who may
claim the property sold or any part thereof from, through or under the Company, its successors and assigns; and 
 F. the receipt
of the Trustee or of the officer making such sale shall be a sufficient discharge to the purchaser or purchasers at such sale for his or their purchase money and such purchaser or purchasers and his or their assigns or personal representatives shall
not, after paying such purchase money and receiving such receipt, be obliged to see to the application of such purchase money, or be in anywise answerable for any loss, misapplication or non-application thereof. 

Upon a sale of substantially all the Trust Estate, whether made under the power of sale hereby given or pursuant to judicial proceedings,
the Company will permit, to the extent permitted by law, the purchaser thereof and its successors and its and their assigns to take and use the name of the Company and to carry on business under such name or any variant or variants thereof and to
use and employ any and all other trade names, brands and trademarks of the Company; and in such event, upon written request of such purchaser or its successors, or its or their assigns, the Company will, at the expense of the purchaser, change its
name in such manner as to eliminate any similarity. 
 Section 9.06. Covenant to Pay Trustee Amounts Due on Obligations
and Right of Trustee to Judgment. 
 The Company covenants that, if: 

A. default is made in the payment of any interest on any Obligation when such interest becomes due and payable, and such default
continues for the period prescribed in Section 9.01(A), or 
 B. default is made in the payment of the principal of (or
premium, if any, on) any Obligation at its Maturity and, if applicable, such default continues for the period prescribed in Section 9.01(B), 
 then upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the Holders of such Obligations, the whole amount then due and payable on such Obligations (including any amount
accelerated pursuant to Section 6.02) for principal (and premium, if any) and interest, with interest at the respective rate or rates prescribed therefor in the Obligations of the several series on overdue principal (and premium, if any) and,
to the extent that payment of such interest is legally enforceable, on overdue installments of interest; and, in addition thereto, all late payment charges and fees, if any, prescribed in such Obligations and such further amount as shall be
sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, shall be entitled to sue for and recover judgment against the Company and any other obligor on the Obligations for the whole amount so due and unpaid and exercise such other rights and
remedies as may be provided by law or otherwise available to the Trustee. 

  
 -89-

 The Trustee shall be entitled to sue and recover judgment as aforesaid either before, after
or during the pendency of any proceedings for the enforcement of the lien of this Indenture, and in case of a sale of the Trust Estate and the application of the proceeds of sale as aforesaid, the Trustee, in its own name and as trustee of an
express trust, shall be entitled to enforce payment of, and to receive, all amounts then remaining due and unpaid upon the Outstanding Secured Obligations, for the benefit of the Holders thereof, and shall be entitled to recover judgment for any
portion of the same remaining unpaid, with interest as aforesaid. No recovery of any such judgment upon any property of the Company shall affect or impair the lien of this Indenture upon the Trust Estate or any rights, powers or remedies of the
Trustee hereunder, or any rights, powers or remedies of the Holders of the Obligations. 
 Section 9.07. Application of
Money Collected. 
 Any money collected by the Trustee pursuant to this Article, including any rents, issues, tolls, profits,
revenues and other income collected pursuant to Section 9.03 (after the deductions therein provided) and any proceeds of any sale (after deducting the costs and expenses of such sale, including a reasonable compensation to the Trustee, its
agents and counsel, and any taxes, assessments or liens prior to the lien of this Indenture, except any thereof subject to which such sale shall have been made), whether made under any power of sale herein granted or pursuant to judicial
proceedings, and any money collected by the Trustee under Sections 6.09 and 16.05 to be applied under this Section, together with, in the case of an entry or sale or as otherwise provided herein, any other sums then held by the Trustee as part of
the Trust Estate, shall be applied in the following order, at the date or dates fixed by the Trustee and, except as otherwise provided in an Obligation or Supplemental Indenture creating the series to which such Obligation belongs, in case of the
distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Obligations and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

A. First: To the payment of all unpaid amounts due the Trustee under Section 10.07 and 16.14;

First: Interest - To the payment to the Persons entitled thereto of all installments of interest then due (and, to the
extent that payment of such interest is legally enforceable, interest on overdue installments of interest) on Outstanding Secured Obligations in the order of the maturity of such installments, together with accrued and unpaid interest on the
Obligations theretofore called for redemption or prepayment, and, if the amount available shall not be sufficient to pay in full any installment or installments maturing on the same date, then to the payment thereof ratably, according to the amounts
due thereon, to the persons entitled thereto, without any discrimination or preference; and 

  
 -90-

 Second: Principal, Premium or Redemption Price - To the payment to the
persons entitled thereto of the unpaid principal and premium, if any and Redemption Price of any Outstanding Secured Obligations which shall have become due, whether at Maturity or by call for redemption or acceleration, and, if the amount available
shall not be sufficient to pay in full all the Obligations which shall have become due, then to the payment thereof ratably, according to the amounts of principal and premium, if any, due, and Redemption Price, to the Persons entitled thereto,
without any discrimination or preference. 
 (2) if the principal of all of the Obligations shall have become due
and payable, to the payment of the principal, premium, if any, and interest then due and unpaid upon the Outstanding Secured Obligations without preference or priority of principal and premium, if any, over interest or of interest over principal and
premium, if any, or of any installment of interest over any other installment of interest, or of any Obligation over any other Obligation, ratably, according to the amounts due respectively for principal, premium, if any, and interest, to the
Persons entitled thereto without any discrimination or preference except as to any difference in the respective rates of interest specified in the Obligations; and 
 C. Third: To the payment of the remainder, if any, to the Company or to whosoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct. 

Until such funds are so distributed, such funds shall be invested by the Trustee in overnight deposits with commercial banks having a
combined capital and surplus of not less than $500 million or in shares of a money market mutual fund or other collective investment fund registered under the Investment Company Act of 1940, whose shares are registered under the Securities Act of
1933, having assets of at least $100 million and having a rating “AAAm” or “AAAm-G” by Standard & Poor’s Ratings Group, including money market mutual funds from which the Trustee or its affiliates derive a fee for
investment advisory or other services to the fund. The interest or other gains on such investments shall be distributed by the Trustee as if such interest or gains were amounts recovered from the Company. 

Section 9.08. Receiver. 
 Upon the occurrence of an Event of Default and commencement of judicial proceedings by the Trustee to enforce any right under this Indenture, the Trustee shall be entitled, as against the Company, without
notice or demand and without regard to the adequacy of the security for the Obligations or the solvency of the Company, to the appointment of a receiver of the Trust Estate, and of the rents, issues, profits, revenues and other income thereof, but,
notwithstanding the appointment of any receiver, the Trustee shall be entitled to retain possession and control of, and to collect and receive the income from, cash, securities and other personal property held by, or required to be deposited or
pledged with, the Trustee hereunder. 

  
 -91-

 Section 9.09. Trustee May File Proofs of Claim. 

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the Obligations or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Obligations shall then
be due and payable, as therein expressed or by declaration or otherwise, and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium or interest) shall be entitled and empowered, by
intervention in such proceeding or otherwise: 
 A. to file and prove a claim for the whole amount of principal (and premium, if
any) and interest owing and unpaid in respect of the Outstanding Secured Obligations and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and 
 B. to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee,
and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Sections 10.07 and 16.14. 
 Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding. 
 Section 9.10. Trustee May Enforce Claims Without
Possession of Obligations. 
 All rights of action and claims under this Indenture or the Obligations may be prosecuted and
enforced by the Trustee without the possession of any of the Obligations or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust.
Any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Obligations in respect of
which such judgment has been recovered. 
 Section 9.11. Limitation on Suits. 

No Holder of any Obligation shall have any right to institute any proceeding, judicial or otherwise, under or with respect to this
Indenture, or for the appointment of a receiver or trustee or for any other remedy hereunder, unless 
 A. such Holder has
previously given written notice to the Trustee of a continuing Event of Default; 

  
 -92-

 B. the Holders of not less than 25% in principal amount of the Outstanding Obligations shall
have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 C. such Holder or Holders (other than a governmental authority) have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request;

 D. the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such
proceeding; and 
 E. no direction inconsistent with such written request has been given to the Trustee during such 60-day
period by the Holders of a majority in principal amount of the Outstanding Obligations; 
 it being understood and intended that no one or more
Holders of Obligations shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the lien of this Indenture or the rights of any other Holders of Obligations, or to
obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all Outstanding Secured Obligations. 

Section 9.12. Unconditional Right of Holders to Receive Principal, Premium and Interest. 

Notwithstanding any other provision in this Indenture, the Holder of any Obligation shall have the absolute and unconditional right to
receive payment of the principal of (and premium, if any) and interest on such Obligation on the respective Stated Maturities expressed in such Obligation (or, in the case of redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 

Section 9.13. Restoration of Positions. 
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture by foreclosure, entry or otherwise and such proceeding has been discontinued or abandoned for
any reason or has been determined adversely to the Trustee or to such Holder, then and in every such case the Company, the Trustee and the Holders shall, subject to any determination in such proceeding, be restored to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 Section 9.14. Rights and Remedies Cumulative. 
 Except as otherwise
provided in the last sentence of Section 3.07, with respect to the replacement or payment of mutilated, destroyed, lost or stolen Obligations or the payment of certain moneys, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy 

  
 -93-

 
shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion
or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 Section 9.15. Delay or Omission Not Waiver. 
 No delay or omission of
the Trustee or of any Holder of any Obligation to exercise any right or remedy accruing upon an Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and
remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

Section 9.16. Control by Holders. 
 The Holders of a majority in principal amount of the Outstanding Obligations shall have the right, during the continuance of an Event of Default, 

A. to require the Trustee to proceed to enforce this Indenture, either by judicial proceedings for the enforcement of the payment of the
Obligations and the foreclosure of this Indenture, the sale of the Trust Estate or otherwise or, at the election of the Trustee, by the exercise of the power of entry and/or sale hereby conferred; and 

B. to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee hereunder, PROVIDED that 
 (1) such direction shall not be in conflict
with any rule of law or this Indenture, 
 (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and 
 (3) the Trustee shall not determine that the action so
directed would be unjustly prejudicial to the Holders not taking part in such direction. 
 Section 9.17. Waiver of Past
Defaults. 
 Before any sale of any of the Trust Estate has been made under this Article or any judgment or decree for
payment of money due has been obtained by the Trustee as provided in this Article, the Holders of not less than a majority in principal amount of the Outstanding Obligations may, by Act of such Holders delivered to the Trustee and the Company, on
behalf of the Holders of all the Obligations waive any past default hereunder and its consequences, except a default 
 A. in
the payment of the principal of (or premium, if any) or interest on any Obligation, or 

  
 -94-

 B. in respect of a covenant or provision hereof which under Article XIII cannot be modified
or amended without the consent of the Holder of each Outstanding Obligation affected. 
 Upon any such waiver, such default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

Section 9.18. Undertaking for Costs. 
 All parties to this Indenture agree, and each Holder of any Obligation by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit,
and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Obligations,
or to any suit instituted by any governmental authority or any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Obligation on or after the respective Stated Maturities expressed in such Obligation
(or, in the case of redemption or acceleration, on or after the Redemption Date or date of acceleration). 

Section 9.19. Waiver of Appraisement and Other Laws. 
 To the full extent that it may lawfully so agree, the Company will not at any time insist upon, plead, claim or take the benefit or advantage of, any appraisement, valuation, stay, extension or redemption
law now or hereafter in force, in order to prevent or hinder the enforcement of this Indenture or the absolute sale of the Trust Estate, or any part thereof, or the possession thereof by any purchaser at any sale under this Article; and the Company,
for itself and all who may claim under it, so far as it or they now or hereafter may lawfully do so, hereby waives the benefit of all such laws. The Company, for itself and all who may claim under it, waives, to the extent that it may lawfully do
so, all right to have the property in the Trust Estate marshalled upon any foreclosure hereof, and agrees that any court having jurisdiction to foreclose this Indenture may order the sale of the Trust Estate as an entirety. 

If any law in this Section referred to and now in force, of which the Company or its successor or successors might take advantage despite
this Section, shall hereafter be repealed or cease to be in force, such law shall not thereafter be deemed to constitute any part of the contract herein contained or to preclude the application of this Section. 

Section 9.20. Suits to Protect the Trust Estate. 
 The Trustee shall have power to institute and to maintain such proceedings as it may deem expedient to prevent any impairment of the Trust Estate by any acts which may be unlawful or in violation of this
Indenture and to protect its interests and the interests of the Holders in the Trust Estate and in the rents, issues, profits, revenues, proceeds, products and 

  
 -95-

 
other income arising therefrom, including power to institute and maintain proceedings to restrain the enforcement of or compliance with any governmental enactment, rule or order that may be
unconstitutional or otherwise invalid, if the enforcement of or compliance with such enactment, rule or order would impair the security hereunder or be prejudicial to the interests of the Holders or the Trustee. 

Section 9.21. Remedies Subject to Applicable Laws. 
 All rights, remedies and powers provided by this Article may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law in the premises, and all the
provisions of this Article are intended to be subject to all applicable mandatory provisions of law which may be controlling in the premises and to be limited to the extent necessary so that they will not render this Indenture invalid, unenforceable
or not entitled to be recorded, registered or filed under the provisions of any applicable law. 
 Section 9.22.
Principal Amount of Original Issue Discount Obligation. 
 The principal amount of an Original Issue Discount Obligation
shall, for purposes of voting, directing the time, place or manner or exercising any remedy, applying moneys, authenticating and delivering Additional Obligations, release of any part of the Trust Estate and for all other purposes hereunder, be
determined in the manner specified in the Supplemental Indenture establishing the series to which such Original Issue Discount Obligation belongs. 
 Section 9.23. Default Not Affecting All Series of Obligations. 
 In
case an Event of Default affecting the rights of the Holders of Obligations of any one or more series which does not similarly affect the rights of Holders of all other series of Obligations at the time Outstanding (including, without limitation, an
Event of Default specified in a Supplemental Indenture creating a series of Obligations) shall have occurred and be continuing, then whatever action (including, without limitation, the acceleration of Obligations under Section 9.02, the giving
of any request or direction to the Trustee under Section 9.11 or 9.16 or the waiver of any default under Section 9.17) may or shall be taken under this Article upon the occurrence of such Event of Default by or upon the request of the
Holders of a specified percentage in principal amount of the Obligations then Outstanding, may or shall be taken in respect of the Obligations then Outstanding of the series as to which such Event of Default shall have been made, by or upon the
request of the Holders of the same percentage in principal amount of the Obligations of such series then Outstanding. 

Section 9.24. Defaults Under Qualifying Securities Indentures. 

In addition to every other right and remedy provided herein, the Trustee may exercise any right or remedy available to the Trustee in its
capacity as owner and holder of Qualifying Securities which arises as a result of a default or a matured event of default under any Qualifying Securities Indenture, whether or not an Event of Default shall then have occurred and be continuing.

in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the

or not they conform to the requirements of this Indenture. 
 B. In case an Event of Default exists, the Trustee shall exercise
such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 

C. No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that 
 (1) this Subsection shall not be

any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

liability is not reasonably assured to it.

to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

repayment or prepayment of the principal of (or premium, if any) or interest on any Obligation or in the payment of any sinking or purchase fund installment, the Trustee shall be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders; and PROVIDED FURTHER that, in the

incurred by it in compliance with such request or direction;

 Section 10.05. May Hold Obligations. 
 The Trustee, any Paying
Agent, Obligation Registrar, Authenticating Agent or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Obligations and, subject to Sections 10.08 and 10.13, if operative, may otherwise deal
with the Company with the same rights it would have if it were not Trustee, Paying Agent, Obligation Registrar, Authenticating Agent or such other agent. 
 Section 10.06. Money Held in Trust.

trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company, the Trustee will

 -100-

 All such payments and reimbursements shall be made with interest at the rate of 10% per annum.

 As security for the performance of the obligations of the Company under this Section, the Trustee shall be secured under this
Indenture by a lien prior to the Obligations, and for the payment of such compensation, expenses, reimbursements and indemnity the Trustee shall have the right to use and apply any Trust Moneys or any other amounts held by it hereunder for the
benefit of any Holders. All indemnities and releases from liability granted to the Trustee herein shall extend to the directors, officers, employees, and agents of the Trustee. The provisions of this Section shall survive the termination of this
Indenture and the resignation or removal of the Trustee. 
 Section 10.08. Disqualification; Conflicting Interests.

 A. If the Trustee has or shall acquire any conflicting interest, as defined in this Section (certain terms being defined
and percentages calculated as hereinafter stated in this Section), if the default to which such conflicting interest relates has not been cured or duly waived or otherwise eliminated within the 90-day period immediately following the date on which
the Trustee ascertains that it has such conflicting interest, it shall, within such 90-day period, either eliminate such conflicting interest or resign in the manner and with the effect hereinafter specified in this Article. 

B. In the event that the Trustee shall fail to comply with the provisions of Subsection (A) of this Section the Trustee shall,
within 10 days after the expiration of such 90-day period, transmit notice of such failure to the Holders in the manner and to the extent provided in Section 11.03(C). 
 C. For the purposes of this Section, the Trustee shall be deemed to have a conflicting interest if there is an Event of Default and 

(1) the Trustee is trustee under another indenture under which any other securities, or certificates of interest or
participation in any other securities, of the Company are outstanding, or is trustee for more than one outstanding series of securities, as hereafter defined, under a single indenture of the Company, unless such other indenture is a collateral trust
indenture under which the only collateral consists of Obligations issued under this Indenture, PROVIDED that there shall be excluded from the operation of this paragraph other series under this Indenture and any indenture or indentures under
which other securities, or certificates of interest or participation in other securities, of the Company are outstanding, if the Company shall have sustained the burden of proving, on application to the Commission and after opportunity for hearing
thereon, that trusteeship under this Indenture and such other indenture or indentures or under more than one outstanding series under a single indenture is not so likely to involve a material conflict of interest as to make it necessary in the
public interest or for the protection of investors to disqualify the Trustee from acting as such under one of such indentures or with respect to such series; or 

  
 -101-

 (2) the Trustee or any of its directors or executive officers is an
underwriter for the Company; or 
 (3) the Trustee directly or indirectly controls or is directly or indirectly
controlled by or is under direct or indirect common control with the Company or an underwriter for the Company; or 
 (4) the Trustee or any of its directors or executive officers is a director, officer, partner, employee, appointee or representative of the Company, or of an underwriter (other than the Trustee itself)
for the Company who is currently engaged in the business of underwriting, except that (a) one individual may be a director or an executive officer or both of the Trustee and a director or an executive officer or both of the Company but may not
be at the same time an executive officer of both the Trustee and the Company; (b) if and so long as the number of directors of the Trustee in office is more than nine, one additional individual may be a director or an executive officer, or
both, of the Trustee and a director of the Company; and (c) the Trustee may be designated by the Company or by any underwriter for the Company to act in the capacity of transfer agent, registrar, custodian, paying agent, fiscal agent, escrow

(6) the Trustee is the beneficial owner of, or holds as collateral security for an obligation which is in default (as
hereinafter in this Subsection defined), (a) 5% or more of the voting securities, or 10% or more of any other class of security, of the Company not including the Obligations issued under this Indenture and securities issued under any other
indenture under which the Trustee is also trustee, or (b) 10% or more of any class of security of an underwriter for the Company; or 
 (7) the Trustee is the beneficial owner of, or holds as collateral security for an obligation which is in default (as hereinafter in this Subsection defined), 5% or more of the voting securities of any
person who, to the knowledge of the Trustee, owns 10% or more of the voting securities of, or controls directly or indirectly or is under direct or indirect common control with, the Company; or 

(8) the Trustee is the beneficial owner of, or holds as collateral security for an obligation which is in default (as
hereinafter in this Subsection defined), 10% or more of any class of security of any person who, to the knowledge of the Trustee, owns 50% or more of the voting securities of the Company; or 

  
 -102-

 (9) the Trustee owns, upon the occurrence of an Event of Default (or any
occurrence that would constitute an Event of Default upon the lapse of time or giving of notice) or any anniversary of such date while such Event of Default or occurrence remains outstanding, in the capacity of executor, administrator, testamentary
or inter vivos trustee, guardian, committee or conservator, or in any other similar capacity, an aggregate of 25% or more of the voting securities, or of any class of security, of any person, the beneficial ownership of a specified percentage
of which would have constituted a conflicting interest under clauses (6), (7) or (8) of this Subsection 10.08(C). As to any such securities of which the Trustee acquired ownership through becoming executor, administrator, or testamentary
trustee of an estate which included them, the provisions of the preceding sentence shall not apply, for a period of two years from the date of such acquisition, to the extent that such securities included in such estate do not exceed 25% of such
voting securities or 25% of any such class of security. Promptly after any Event of Default (or other occurrence that would constitute an Event of Default upon the lapse of time or giving of notice) and annually in each succeeding year that any
Event of Default or other occurrence remains outstanding, the Trustee shall make a check of its holdings of such securities in any of the above-mentioned capacities as of such dates. If the Company fails to make payment in full of the principal of,
or the premium, if any, or interest on, any of the Obligations when and as the same becomes due and payable, and such failure continues for 30 days thereafter, the Trustee shall make a prompt check of its holdings of such securities in any of the
above-mentioned capacities as of the date of the expiration of such 30-day period, and after such date, notwithstanding the foregoing provisions of this clause, all such securities so held by the Trustee, with sole or joint control over such
securities vested in it, shall, but only so long as such failure shall continue, be considered as though beneficially owned by the Trustee for the purposes of clauses (6), (7) and (8) of this Subsection; or 

(10) except under the circumstances described in clauses (1) (3), (4), (5) or (6) of Subsection 10.13(B),
the Trustee shall become a creditor of the Company. 
 For purposes of clause (1) of this Subsection, the term “series
of securities” or “series” means a series, class or group of securities issuable under an indenture pursuant to whose terms holders of one such series may vote to direct the Trustee, or otherwise take action pursuant to a vote of such
Holders, separately from Holders of another such series; PROVIDED that “series of securities” or “series” shall not include any series of securities issuable under an indenture if all such series rank equally and are
wholly unsecured. 
 The specification of percentages in clauses (5) to (9) inclusive, of this Subsection, shall not
be construed as indicating that the ownership of such percentages of the securities of a person is or is not necessary or sufficient to constitute direct or indirect control for the purposes of clause (3) or (7) of this Subsection.

 For the purposes of clauses (6), (7), (8) and (9) of this Subsection only, (a) the terms
“security” and “securities” shall include only such securities as are generally known as corporate securities, but shall not include any note or other evidence of indebtedness issued to evidence an obligation to
repay moneys lent to a person by one or more banks, trust companies or banking firms, or any certificate of interest or participation in any such note or evidence of 

  
 -103-

 
indebtedness; (b) an obligation shall be deemed to be in “default” when a default in payment of principal shall have continued for 30 days or more and shall not have been
cured; and (c) the Trustee shall not be deemed to be the owner or holder of (i) any security which it holds as collateral security, as trustee or otherwise, for an obligation which is not in default as defined above, or (ii) any
security which it holds as collateral security under this Indenture, irrespective of any default hereunder, or (iii) any security which it holds as agent for collection, or as custodian, escrow agent, or depositary, or in any similar
representative capacity. 
 Except in the case of the failure to pay, repay or prepay the principal of or interest on any
Obligation, or to pay any sinking or purchase fund installment, on the date on which it becomes due, the Trustee shall not be required to resign as provided by this Subsection if such Trustee shall have sustained the burden of proving, on
application to the Commission and after opportunity for hearing thereon, that: 
 (a) the Event of Default (or
other event that would constitute an Event of Default upon the passage of time or giving of notice) otherwise giving rise to an obligation by the Trustee to resign may be cured or waived during a reasonable period and under the procedures described
in such application, and 
 (b) a stay of the Trustee’s duty to resign will not be inconsistent with the
interests of Holders of the Obligations. The filing of such an application shall automatically stay the performance of the duty to resign until the Commission orders otherwise. 

Any resignation of the Trustee shall become effective only upon the appointment of a successor trustee and such successor’s
acceptance of such an appointment. 
 D. For the purposes of this Section: 

(1) The term “underwriter” when used with reference to the Company means every person who, within one
year prior to the time as of which the determination is made, has purchased from the Company with a view to, or has offered or sold for the Company in connection with, the distribution of any security of the Company outstanding at such time, or has

to be of the same class as another security if both securities confer upon the holder or holders thereof substantially the same rights and privileges; PROVIDED, HOWEVER, that, in the case of secured evidences of indebtedness, all of which are
issued under a single indenture, differences in the interest rates or maturity dates of various series thereof shall not be deemed sufficient to constitute such series as different classes, and PROVIDED FURTHER that, in the case of unsecured
evidences of indebtedness, differences in the interest rates or maturity dates thereof shall not be deemed sufficient to constitute them securities of different classes, whether or not they are issued under a single indenture. 

Section 10.09. Corporate Trustee Required; Eligibility.

until a new Trustee shall be so appointed by the Holders. If, within one year after such resignation, removal or incapability or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal
amount of the Outstanding Obligations delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company or by such receiver or trustee. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, subject to Section 9.18, any Holder who has
been a bona fide Holder of an Obligation for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. 

F. The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee by

Trustee in writing. Each notice shall include the name of the successor Trustee and the address of its principal corporate trust office. Upon the appointment of a new Trustee in the place of, any Trustee named herein acting hereunder, an instrument,

 -107-

 G. Upon the resignation, removal or incapability of the Trustee, all books and records of
the Trustee relating to the Trust Estate shall be sent to the successor Trustee within 60 days of such resignation, removal or incapability. In the event (1) the Trustee resigns due to any conflict of interest or incapability,
(2) there is any change in control, merger, conversion, consolidation or succession to the assets of the Trustee or (3) the Company removes the Trustee as a result of any such change in control, merger, conversion, consolidation or
succession, the Trustee shall pay all reasonable costs associated with transferring the Trust Estate to a successor Trustee. 

Section 10.11. Acceptance of Appointment by Successor. 

Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the estates,
properties, rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument conveying and transferring to
such successor Trustee upon the trusts herein expressed all the estates, properties, rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such
retiring Trustee hereunder, subject nevertheless to its lien, if any, provided for in Sections 10.07 and 16.14. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting

shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article, to the extent operative. 
 Section 10.12. Merger, Conversion, Consolidation or Succession to Business. 
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall
be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, PROVIDED such corporation shall be otherwise qualified and eligible under
this Article, to the extent operative, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Obligations shall have been authenticated, but not delivered, by the Trustee then in office,
any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Obligations so authenticated with the same effect as if such successor Trustee had itself authenticated such
Obligations. 

  
 -108-

 Section 10.13. Preferential Collection of Claims against Company. 

A. Subject to Subsection (B) of this Section, if the Trustee shall be or shall become a creditor, directly or indirectly, secured or
unsecured, of the Company within three months prior to a default (as defined in Subsection (C) of this Section), or subsequent to such a default, then, unless and until such default shall be cured, the Trustee shall set apart and hold in a
special account for the benefit of the Trustee individually, the Holders of the Obligations and the holders of other indenture securities (as defined in Subsection (C) of this Section): 

(1) an amount equal to any and all reductions in the amount due and owing upon any claim as such creditor in respect of
principal or interest, effected after the beginning of such three-month period and valid as against the Company and its other creditors, except any such reduction resulting from the receipt or disposition of any property described in clause
(2) of this Subsection, or from the exercise of any right of set-off which the Trustee could have exercised if a petition in bankruptcy had been filed by or against the Company upon the date of such default; and 

(2) all property received by the Trustee in respect of any claim as such creditor, either as security therefor, or in
satisfaction or composition thereof, or otherwise, after the beginning of such three month period, or an amount equal to the proceeds of any such property, if disposed of, SUBJECT, HOWEVER, to the rights, if any, of the Company and its
other creditors in such property or such proceeds. 
 Nothing herein contained, however, shall affect the right of the Trustee

 (a) to retain for its own account (i) payments made on account of any such claim by any Person (other
than the Company) who is liable thereon, and (ii) the proceeds of the bona fide sale of any such claim by the Trustee to a third person, and (iii) distributions made in cash, securities or other property in respect of claims filed against
the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Code or applicable state law; or 
 (b) to realize, for its own account, upon any property held by it as security for any such claim, if such property was so held prior to the beginning of such three months’ period; or 

(c) to realize, for its own account, but only to the extent of the claim hereinafter mentioned, upon any property held by
it as security for any such claim, if such claim was created after the beginning of such three months’ period and such property was received as security therefor simultaneously with the creation thereof, and if the Trustee shall sustain the
burden of proving that at the time such property was so received the Trustee had no reasonable cause to believe that a default would occur within three months; or 

(d) to receive payment on any claim referred to in clause (b) or (c), against the release of any property held as
security for such claim as provided in clause (b) or (c), as the case may be, to the extent of the fair value of such property. 

  
 -109-

 For the purposes of clauses (b), (c) and (d), property substituted after the beginning
of such three months’ period for property held as security at the time of such substitution shall, to the extent of the fair value of the property released, have the same status as the property released, and, to the extent that any claim
referred to in any of said clauses is created in renewal of or in substitution for or for the purpose of repaying or refunding any pre-existing claim of the Trustee as such creditor, such claim shall have the same status as such pre-existing claim.

 If the Trustee shall be required to account, the funds and property held in such special account and the proceeds thereof
shall be apportioned among the Trustee, the Holders and the holders of other indenture securities in such manner that the Trustee, the Holders and the holders of other indenture securities realize, as a result of payments from such special account
and payments of dividends on claims filed against the Company in bankruptcy or receivership or in proceedings for liquidation or reorganization pursuant to the Federal Bankruptcy Code or applicable state law, the same percentage of their respective
claims, figured before crediting to the claim of the Trustee anything on account of the receipt by it from the Company of the funds and property in such special account and before crediting to the respective claims of the Trustee and the Holders and
the holders of other indenture securities dividends on claims filed against the Company in bankruptcy or receivership or in proceedings for liquidation or reorganization pursuant to the Federal Bankruptcy Code or applicable state law, but after
crediting thereon receipts on account of the indebtedness represented by their respective claims from all sources other than from such dividends and from the funds and property so held in such special account. As used in this paragraph, with respect
to any claim, the term “dividends” shall include any distribution with respect to such claim, in bankruptcy or receivership or proceedings for reorganization pursuant to the Federal Bankruptcy Code or applicable state law, whether
such distribution is made in cash, securities, or other property, but shall not include any such distribution with respect to the secured portion, if any, of such claim. The court in which such bankruptcy, receivership or proceedings for
reorganization is pending shall have jurisdiction (i) to apportion among the Trustee, the Holders and the holders of other indenture securities, in accordance with the provisions of this paragraph, the funds and property held in such special
account and proceeds thereof, or (ii) in lieu of such apportionment, in whole or in part, to give to the provisions of this paragraph due consideration in determining the fairness of the distributions to be made to the Trustee and the Holders
and the holders of other indenture securities with respect to their respective claims, in which event it shall not be necessary to liquidate or to appraise the value of any securities or other property held in such special account or as security for
any such claim, or to make a specific allocation of such distributions as between the secured and unsecured portions of such claims, or otherwise to apply the provisions of this paragraph as a mathematical formula. 

Any Trustee which has resigned or been removed after the beginning of such three months’ period shall be subject to the provisions
of this Subsection as though such resignation or removal had not occurred. If any Trustee has resigned or been removed prior to the beginning of such three months’ period, it shall be subject to the provisions of this Subsection if and only if
the following conditions exist: 
  

	 	(i)	the receipt of property or reduction of claim, which would have given rise to the obligation to account, if such Trustee had continued as Trustee, occurred after the
beginning of such three months’ period; and 

  
 -110-

	 	(ii)	such receipt of property or reduction of claim occurred within three months after such resignation or removal. 

B. There shall be excluded from the operation of Subsection (A) of this Section a creditor relationship arising from: 

(1) the ownership or acquisition of securities issued under any indenture or any security or securities having a maturity
of one year or more at the time of acquisition by the Trustee; or 
 (2) advances authorized by a receivership or
bankruptcy court of competent jurisdiction, or by this Indenture, for the purpose of preserving any property which shall at any time be subject to the lien of this Indenture or of discharging tax liens or other prior liens or encumbrances thereon,
if notice of such advances and of the circumstances surrounding the making thereof is given to the Holders at the time and in the manner provided in this Indenture; or 

(3) disbursements made in the ordinary course of business in the capacity of trustee under an indenture, transfer agent,
registrar, custodian, paying agent, fiscal agent or depositary, or other similar capacity; or 
 (4) an
indebtedness created as a result of services rendered or premises rented; or an indebtedness created as a result of goods or securities sold in a cash transaction (as defined in Subsection (C) of this Section); or 

(5) the ownership of stock or of other securities of a corporation organized under the provisions of Section 25(a) of
the Federal Reserve Act, as amended, which is directly or indirectly a creditor of the Company; or the acquisition, ownership, acceptance or negotiation of any drafts, bills of exchange, acceptances or obligations which fall within the
classification of self-liquidating paper (as defined in Subsection (C) of this Section). 
 C. For the purposes of this
Section only:

principal of or interest on any of the Obligations or upon the other indenture securities when and as such principal or interest become due and payable; 
 (2) The term “other indenture securities” means securities upon which the Company is an obligor outstanding under any other indenture (a) under which the Trustee is also trustee,
(b) which contains provisions substantially similar to the provisions of this Section, and (c) under which a default exists at the time of the apportionment of the funds and property held in such special account; 

  
 -111-

 (3) The term “cash transaction” means any transaction in
which full payment for goods or securities sold is made within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand;

is made, drawn, negotiated or incurred by the Company for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession
of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, PROVIDED the security is received by the Trustee simultaneously
with the creation of the creditor relationship with the Company arising from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation; 

(5) The term “Company” means any obligor upon the Obligations; 

(6) The term “Federal Bankruptcy Code” means Title 11 of the United States Code, as it may be amended
from time to time; and 
 (7) The term “Trustee” includes any separate or co-trustee appointed
under Section 10.14.

At any time or times, for the purpose of meeting the legal requirements of any jurisdiction in which any of the Trust Estate may at the
time be located, the Company and the Trustee shall have power to appoint, and, upon the written request of the Trustee or of the Holders of at least 25% in principal amount of the Obligations Outstanding, the Company shall for such purpose join with
the Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to appoint, one or more Persons approved by the Trustee either to act as co-trustee, jointly with the Trustee, of all or any part of the
Trust Estate, or to act as separate trustee of any such property, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person or Persons in the capacity aforesaid, any property, title, right or
power deemed necessary or desirable, subject to the other provisions of this Section. If the Company does not join in such appointment within 15 days after the receipt by it of a request so to do, or in case an Event of Default has occurred and is
continuing, the Trustee alone shall have power to make such appointment. 
 Should any written instrument from the Company be
required by any co-trustee or separate trustee so appointed for more fully confirming to such co-trustee or separate trustee such property, title, right or power, any and all such instruments shall, on request, be executed, acknowledged and
delivered by the Company. 

  
 -112-

 Every co-trustee or separate trustee shall, to the extent permitted by law, but to such
extent only, be appointed subject to the following terms, namely: 
 A. The Obligations shall be authenticated and delivered,
and all rights, powers, duties and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or required to be deposited or pledged with, the Trustee hereunder, shall be exercised solely, by the
Trustee. 
 B. The rights, powers, duties and obligations hereby conferred or imposed upon the Trustee in respect of any

the Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee or separate trustee so resigned or removed may be appointed in the
manner provided in this Section. 
 D. No co-trustee or separate trustee hereunder shall be personally liable by reason of any
act or omission of the Trustee, or any other such trustee hereunder.

need not include information received after such date. 
 Section 11.02. Preservation of Information; Communications to

 B. If three or more Holders of Obligations (hereinafter referred to as
“applicants”) apply in writing to the Trustee, and furnish to the Trustee reasonable proof that each such applicant has owned an Obligation for a period of at least six months preceding the date of such application, and such
application states that the applicants desire to communicate with other Holders of Obligations with respect to their rights under this Indenture or under the Obligations and is accompanied by a copy of the form of proxy or other communication which
such applicants propose to transmit, then the Trustee shall, within five business days after the receipt of such application, at its election, either 

(1) afford such applicants access to the information preserved at the time by the Trustee in accordance
with Section 11.02(A), or 
 (2) inform such applicants as to the approximate number of Holders of
Obligations whose names and addresses appear in the information preserved at the time by the Trustee in accordance with Section 11.02(A), and as to the approximate cost of mailing to such Holders the form of proxy or other communication, if any
specified in such application. 
 If the Trustee shall elect not to afford such applicants access to such information, the
Trustee shall, upon the written request of such applicants, mail to each Holder whose name and address appear in the information preserved at the time by the Trustee in accordance with Section 10.02(A), a copy of the form of proxy or other

after such tender, the Trustee shall mail to such applicants and file with the Commission, together with a copy of the material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to
the best interests of the Holders of Obligations or would be in violation of applicable law. Such written statement shall specify the basis of such opinion. If the Commission, after opportunity for a hearing upon the objections specified in the
written statement so filed, shall enter an order refusing to sustain any of such objections or if, after the entry of an order sustaining one or more of such objections, the Commission shall find, after notice and opportunity for hearing, that all
the objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail copies of such material to all such Holders with reasonable promptness after the entry of such order and the renewal of such tender; otherwise
the Trustee shall be relieved of any obligation or duty to such applicants respecting their application.

Obligations, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any Paying Agent shall be held accountable by reason of the disclosure of any such information as to the names and
addresses of the Holders of Obligations in accordance with Section 11.02(B), regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a
request made under Section 11.02(B).

the Obligations, on the Trust Estate or on any property or funds held or collected by it as Trustee, and which it has not previously reported pursuant to this Subsection, except that the Trustee shall not be required (but may elect) to report such
advances if such advances remaining unpaid at any time aggregate 10% or less of the principal amount of the Obligations Outstanding at such time, such report to be transmitted within 90 days after such time.

affect or diminish the rights of the Holders of any Obligations then Outstanding against the Company or its property, it shall expressly be stated in such Supplemental Indenture that any such modifications or eliminations shall become effective only
when there is no Obligation Outstanding of any series created prior to, the execution of such Supplemental Indenture; and 
 (2) the Trustee may, in its discretion, decline to enter into any such Supplemental Indenture which, in its opinion, may not afford adequate protection to the Trustee when the same becomes operative; or

 H. to cure any ambiguity, to correct or
supplement any provision herein which may be inconsistent with any other provision herein or to make any other provisions, with respect to matters or questions arising under this Indenture, which shall not be inconsistent with the provisions of this
Indenture, PROVIDED such action shall not in the opinion of the Company, as evidenced by an Officers’ Certificate delivered to the Trustee, adversely affect the interests of the Holders of the Obligations in any material respect; or

 I. to modify, eliminate or add to the provisions of this Indenture to such extent as shall be necessary to effect the
qualification of this Indenture under the TIA or under any similar federal statute hereafter enacted, to add to this Indenture such other provisions as may be expressly permitted by the TIA and to modify, eliminate or add to the provisions of this
Indenture to the extent that any such provisions relating to requirements under the TIA have been modified or eliminated in the TIA after the date of this instrument, EXCLUDING, HOWEVER, the provisions referred to in Section 316(a)(2) of

that are not subject to Credit Enhancement will not be withdrawn or reduced as a result of the changes in the Indenture effected by such Supplemental Indenture; PROVIDED, HOWEVER, that the failure to qualify for the presumption set
forth in this sentence shall not create any presumption 

  
 -122-

 
to the contrary or be used to question the judgment of the Trustee; PROVIDED, FURTHER, that the provisions of this Subsection may not be used to amend or modify the items listed in
Subsections (A) through (F) of Section 13.02 hereof in any way that is inconsistent with the provisions of such Section 13.02. The Trustee may rely on the written evidence of the nationally recognized statistical rating
organizations then rating the Obligations (or other obligations primarily secured by Outstanding Obligations) with respect to credit matters relating to the Company to the extent that it deems such reliance to be appropriate. 

Section 13.02. Supplemental Indentures With Consent of Holders. 

With the consent of the Holders of not less than a majority in principal amount of the Obligations of all series then Outstanding affected
by such Supplemental Indenture, by Act of such Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may enter into a Supplemental Indenture for the purpose of adding any provisions to

E. permit the creation of any lien (other than as permitted in this Indenture) ranking prior to or on a parity with the lien of this
Indenture with respect to all or substantially all of the Trust Estate or terminate the lien of this Indenture on all or substantially all of the Trust Estate except to the extent already permitted hereby; or 

F. modify, in the case of Obligations of any series for which a mandatory sinking fund is provided, any of the provisions of this
Indenture in such manner as to affect the rights of the Holders of such Obligations to the benefits of such sinking fund; or 

  
 -123-

 G. modify Section 9.07 of this Indenture.

 The Company will maintain an office or agency in each Place of Payment where Obligations may be presented or surrendered
for payment, where Obligations entitled to be registered, transferred, exchanged or converted may be presented or surrendered for registration, transfer, exchange or conversion and where notices and demands to or upon the Company in respect of the
Obligations and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency. If at any time the Company shall fail to maintain such an
office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the principal corporate trust office of the Trustee, and the Company hereby appoints the
Trustee its agent to receive all such presentations, surrenders, notices and demands. 
 Section 14.03. Money for
Obligation Payments to be Held in Trust; Repayment of Unclaimed Money. 
 If the Company shall at any time act as its own
Paying Agent, it will, on or before each due date of the principal of (and premium, if any) or interest on any of the Obligations, segregate and hold in trust for the benefit of the Holders of such Obligations a sum sufficient to pay the principal
(and premium, if any) or interest so becoming due until such sums shall be paid to such Holders or otherwise disposed of as herein provided, and the Company will promptly notify the Trustee of its action or failure so to act. 

Whenever the Company shall have one or more Paying Agents, it will, prior to each due date of the principal of (and premium, if any) or
interest on any Obligations, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Holders of such Obligations entitled to such
principal (and premium, if any) or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
 Moneys so segregated or deposited and held in trust shall not be a part of the Trust Estate and shall not be deemed Trust Moneys but shall constitute a separate trust fund for the benefit of the Persons
entitled to such principal, premium or interest. Except in the case of moneys so segregated by the Company when acting as its own Paying Agent, moneys held in trust by the Trustee or any other Paying Agent for the payment of the principal (or
premium, if any) or interest on the Obligations need not be segregated from other funds, except to the extent required by law. 

  
 -125-

 The Company will cause each Paying Agent other than the Company and the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will 
 A. hold all sums held by it for the payment of principal of (and premium, if any) or interest on Obligations in trust for the benefit of the Holders of such Obligations until such sums shall be paid to
the Holders or otherwise disposed of as herein provided; 
 B. give the Trustee notice of any default by the Company (or any
other obligor upon the Obligations) in the making of any payment of principal (and premium, if any) or interest; and 
 C. at
any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee
all money held in trust by the Company or such Paying Agent, such money to be held by the Trustee upon the same trusts as those upon which such money was held by the Company or such Paying Agent; and, upon such payment by the Company, the Company
shall be discharged from such trust, and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 

Any money deposited with the Trustee or any Paying Agent or held by the Company in trust for the payment of the principal of (and
premium, if any) or interest on any Obligation and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Obligation shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon cease.

specifically described in Granting Clause First and Second (other than property that is released from the lien of this Indenture pursuant to the provisions hereof) against the claims and demands of all persons whomsoever, except Permitted
Encumbrances.

All property of every kind, other than Excepted Property and Excludable Property, acquired by the Company after the date hereof, shall,
immediately upon the acquisition thereof by the Company, and without any further mortgage, conveyance or assignment, become subject to the lien of this Indenture; SUBJECT, HOWEVER, to the exceptions, if any, permitted by
Section 12.02. Nevertheless, the Company will do, execute, acknowledge and deliver all and every such further acts, conveyances, mortgages, financing statements and assurances as the Trustee shall require for accomplishing the purposes of this

registered and filed, or have been received for recording, filing or registration, to the extent necessary to make effective the lien intended to be created by this Indenture, and reciting the details of such action or referring to prior Opinions of
Counsel in which such details are given, and stating that all financing statements and continuation statements have been executed and filed that are necessary fully to preserve and protect the rights of the Holders and the Trustee hereunder, or

 Upon the cancellation and discharge of any Prior Lien, the Company
may receive all cash, obligations and securities then held by the trustee, mortgagee or other holder of such Prior Lien, which were received by such trustee, mortgagee or other holder on account of the release or the taking by eminent domain or the
purchase by a public authority or the sale by virtue of a designation or order of a public authority or any other disposition of, or insurance on, the Trust Estate, or any part thereof (including all proceeds of or substitutions for any thereof).

 Section 14.06. Limitations on Liens; Payment of Taxes. 

The Company will not create or incur or suffer or permit to be created or incurred or to exist any mortgage, lien, charge or encumbrance
on or pledge of any of the Trust Estate, prior to or upon a parity with the lien of this Indenture except Permitted Encumbrances and except that: 
 A. The Company may create, incur or suffer to exist purchase money mortgages or other purchase money liens upon any real property purchased by the Company or acquire real property subject to mortgages and

by such mortgages, liens and agreements (including extensions, renewals and replacements thereof, as provided by the following Subsection (B), and also the indebtedness then being incurred) shall not exceed 10% of the aggregate principal amount of
all Outstanding Secured Obligations; and 
 (3) each such mortgage, lien or agreement shall apply only to the
property originally subject thereto and fixed improvements erected on such real property or affixed to such personal property or equipment used in connection with such real or personal property. 

  
 -128-

 B. The Company may modify, extend, renew or replace any mortgage, lien or agreement
permitted by Subsection A above upon the same property theretofore subject thereto, or modify, replace, renew or extend the indebtedness secured thereby, PROVIDED that in any such case the principal amount of such indebtedness so modified,
replaced, extended or renewed shall not be increased. 
 The Company will pay or cause to be paid as they become due and payable
all taxes, assessments and other governmental charges lawfully levied or assessed or imposed upon the Trust Estate or any part thereof or upon any income therefrom, and also (to the extent that such payment will not be contrary to any applicable
laws) all taxes, assessments and other governmental charges lawfully levied, assessed or imposed upon the lien or interest of the Trustee or of the Holders in the Trust Estate, so that (to the extent aforesaid) the lien of this Indenture shall at
all times be wholly preserved at the cost of the Company and without expense to the Trustee or the Holders; PROVIDED, HOWEVER, that the Company shall not be required to pay and discharge or cause to be paid and discharged any such tax,
assessment or governmental charge to the extent that the amount, applicability or validity thereof shall currently be contested in good faith by appropriate proceedings and the Company shall have established and shall maintain adequate reserves on
its books for the payment of the same. 
 Section 14.07. Maintenance of Properties. 

The Company will cause all its properties used or useful in the conduct of its business to be maintained and kept in good condition,
repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously conducted at all times; PROVIDED, HOWEVER, that nothing in this Section shall prevent the Company from discontinuing the operation and maintenance of any of
its properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business and not disadvantageous in any material respect to the Holders. 

The Company will promptly classify, and record on its books, as retired, all property that has become no longer used or useful in the
business of the Company. 
 Section 14.08. To Insure. 

The Company will at all times keep all its property of an insurable nature and of the character usually insured by companies operating
similar properties, insured in amounts customarily carried, and against loss or damage from such causes as are customarily insured against, by similar companies. All such insurance shall be effected with responsible insurance carriers. All policies
or other contracts for such insurance upon any part of the Trust Estate shall provide that the proceeds of such insurance (except in the case of any particular casualty resulting in damage or destruction not exceeding $1,000,000 in the aggregate)
shall be payable, subject to the requirements of any Prior Lien, to the Trustee as its interest may appear (by means of a standard mortgagee clause or other similar clause acceptable to the Trustee, without contribution). Each policy or other
contract for such insurance, or such mortgagee clause, shall contain an agreement by the insurer that, notwithstanding any right of cancellation reserved to 

  
 -129-

 
such insurer, such policy or contract shall continue in force for the benefit of the Trustee for at least 30 days after written notice to the Trustee of cancellation; PROVIDED, HOWEVER,
that in the event of cancellation due to non-payment of premiums said notice shall be ten days. As soon as practicable after the execution of this Indenture, and within 90 days after the close of each calendar year thereafter, and at any time upon
the request of the Trustee, the Company will deliver to the Trustee an Officers’ Certificate containing a detailed list of the insurance in force upon the Trust Estate on a date therein specified (which date shall be within 30 days of the
delivery of such Certificate), including the names of the insurers with which the policies and other contracts of insurance on the Trust Estate are carried, the numbers, amounts and expiration dates of such policies and other contracts and the
property and hazards covered thereby, and stating that the insurance so listed complies with this Section. 
 Any appraisement
or adjustment or any loss or damage of or to any part of the Trust Estate and any settlement in respect thereof which may be agreed upon between the Company and any insurer, as evidenced by an Officers’ Certificate, shall be accepted by the
Trustee. 
 All proceeds of insurance received by the Trustee shall be held and paid over or applied by the Trustee as provided
in Article VII. 
 All proceeds of any insurance on any part of the Trust Estate not payable to the Trustee or the trustee,
mortgagee or other holder of a Prior Lien shall be applied by the Company to the repair, rebuilding or replacement of the property destroyed or damaged or shall be deposited with the Trustee to be held and paid over or applied by it as provided in
Article VII. 
 Section 14.09. Corporate Existence. 

Subject to Article XII, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its
corporate existence, rights (charter and statutory) and franchises; PROVIDED, HOWEVER, that the Company shall not be required to preserve any right or franchise if the Board of Directors shall determine that the preservation thereof is
no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders, as evidenced by an Officers’ Certificate delivered to the Trustee certifying the action
of the Board of Directors and containing an explanation of the factors considered by the Board of Directors in taking such action. 
 Section 14.10. To Keep Books; Inspection by Trustee. 
 The Company will
keep proper books of record and account, in which full and correct entries shall be made of all dealings or transactions of or in relation to the Obligations and the plant, properties, business and affairs of the Company in accordance with
Accounting Requirements. The Company will, upon reasonable written notice by the Trustee to the Company and at the expense of the Company, permit the Trustee by its representatives to inspect the plants and properties, books of account, records,
reports and other papers of the Company, and to take copies and extracts therefrom, and will afford and procure a reasonable opportunity to make any such inspection, and the Company will furnish to the Trustee any and all information as the Trustee
may reasonably request, with respect to the performance by the Company of its covenants in this Indenture; PROVIDED, HOWEVER, the Company shall not be required to make available any information supplied to it by a third party which is
subject to a confidentiality agreement with such third party except to the extent allowed by, and subject to the terms of such confidentiality agreement. 

  
 -130-

 Section 14.11. Use of Trust Moneys and Advances by Trustee. 

If the Company shall fail to perform any of its covenants in this Indenture, the Trustee may, at any time and from time to time after
notice to the Company, use and apply any Trust Moneys held by it under Article VII, or make advances, to effect performance of any such covenant on behalf of the Company; and all moneys so used or advanced by the Trustee, together with interest at
the lesser of (i) the rate of 10% per annum or (ii) the maximum rate permitted by law, shall be repaid by the Company upon demand and such advances shall be secured under this Indenture prior to the Obligations. For the repayment of
all such advances the Trustee shall have the right to use and apply any Trust Moneys at any time held by it under Article VII but no such use of Trust Moneys or advances shall relieve the Company from any default hereunder. 

Section 14.12. Statement as to Compliance. 
 The Company will deliver to the Trustee, within 120 days after the end of each calendar year, a written statement signed by the principal executive officer and by the principal financial officer or
principal accounting officer of the Company stating that a review of the Company’s activities during the preceding calendar year has been made under his supervision and that the Company has fulfilled its obligations hereunder in all material
respects during such calendar year. 
 Promptly after any Officer of the Company may reasonably be deemed to have knowledge of a
default hereunder, the Company will deliver to the Trustee a written notice specifying the nature and period of existence thereof and the action the Company is taking and proposes to take with respect thereto. 

Section 14.13. Waiver of Certain Covenants. 
 The Company may omit in any particular instance to comply with any covenant or condition set forth in this Article except Sections 14.01, 14.02, 14.03, 14.04, 14.05, 14.09, 14.10 and 14.11 if before or
after the time for such compliance the Holders of at least a majority in principal amount of all Obligations then Outstanding, shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in
respect of any such covenant or condition shall remain in full force and effect. 
 Section 14.14. Rate Covenant.

 The Company shall establish and collect rates, rents, charges, fees and other compensation (collectively,
“Rates”) that, together with other moneys available to the Company, produce moneys sufficient to enable the Company to comply with all its covenants under this Indenture. Subject to any necessary regulatory approval or
determination, the Company also shall establish and collect Rates that, together with other revenues available to the Company, are 

  
 -131-

 
reasonably expected to yield Margins for Interest for each fiscal year of the Company equal to at least 1.10 times Interest Charges for such period. Promptly upon any material change in the
circumstances which were contemplated at the time such Rates were most recently reviewed, but not less frequently than once every twelve months, the Company shall review the Rates so established and shall, within three months of such review,
establish or revise such Rates as necessary to comply with the foregoing requirements; PROVIDED, HOWEVER, that if (i) upon any such review of Rates based on a material change in circumstances, the Company determines that Rates are
required to be established or revised in order for the Company to comply with this Section 14.14 and (ii) there are less than six calendar months remaining in the current fiscal year, it will be sufficient for purposes of complying with
this Section 14.14 if the Company establishes or revises its Rates so as to reasonably expect to meet the covenant for the next succeeding twelve month period commencing with the first day of the calendar month next succeeding the date of any
such revision, subject in the case of the foregoing Margins for Interest requirement to any necessary regulatory approval or determination. 
 Section 14.15. Distributions to Members. 
 The Company shall not
directly or indirectly declare or pay any dividend or make any payments, distributions or retirements of patronage capital to members (each a “Distribution”) if, at the time thereof or after giving effect thereto, (i) an Event
of Default shall exist, or (ii) the Company’s patronage capital (determined in accordance with Accounting Requirements) as of the end of the Company’s most recent fiscal quarter would be less than 20% of the Company’s total
long-term debt and patronage capital (determined in accordance with Accounting Requirements) at such time. Notwithstanding the foregoing and so long as no Event of Default shall exist, the Company may declare and make Distributions each fiscal year
as long as the aggregate Distributions for such fiscal year are equal to or less than 5% of the Company’s patronage capital (determined in accordance with Accounting Requirements) as of the end of the immediately preceding fiscal year. For
purposes of this Section, determination of patronage capital and total long-term debt and patronage capital shall not include any amount on account of earnings retained in any Subsidiary or Affiliate of the Company and any such determination of
total long-term debt and patronage capital shall exclude the debt of any Subsidiary or Affiliate. 
 ARTICLE XV

 REDEMPTION OF OBLIGATIONS; SINKING FUNDS 
 Section 15.01. General Applicability of Sections 15.01 through 15.07. 

Obligations which are by their express terms redeemable before their Stated Maturity shall be redeemable in accordance with their terms
and (except as otherwise provided with respect to the Obligations of any particular series by the provisions of this Indenture creating such series) in accordance with Sections 15.01 through 15.07. 

  
 -132-

 Section 15.02. Election to Redeem; Notice to Trustee. 

The election of the Company to redeem any Obligations shall be evidenced by a Board Resolution. In case of any redemption at the election
of the Company of less than all the Outstanding Obligations of any series, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee) notify the Trustee of
such Redemption Date and of the principal amount of Obligations of such series to be redeemed and of the numbers of any Outstanding Obligations of such series then owned by the Company. 

If at the time the Company provides notice of redemption to the Trustee pursuant to this Section, the Trustee or a Paying Agent does not
have on deposit (which, if the Company is the Paying Agent, shall be segregated and held in trust as provided in Section 14.03) sufficient available funds to pay the Redemption Price for the Obligations so called for redemption, then the notice
of redemption shall be conditional and revocable; that is, the Company is under no obligation to deposit or provide, or cause to be deposited or provided, to the Trustee funds to effect such redemption and, if it does not elect to do so by 2:00
p.m., New York City time, on the Redemption Date, then the Obligations called for redemption shall not be redeemed pursuant to the above-mentioned notice of redemption or the notice of redemption given to the Holders pursuant to Section 15.04.

 If the Obligations of any series to be redeemed consist of Obligations having different Stated Maturities or different rates
of interest (or methods of computing interest), then the Company may, in the notice delivered to the Trustee pursuant to this Section, direct that the Securities of such series to be redeemed shall be selected from among groups of such Obligations
having specified Stated Maturities or rates of interest (or methods of computing interest) and the Trustee shall thereafter select the particular Obligations to be redeemed in the manner set forth below from among the groups of Obligations so
specified. 
 Section 15.03. Selection by Trustee of Obligations to be Redeemed. 

Unless otherwise provided in a Supplemental Indenture authorizing a particular series of Obligations, if less than all the Outstanding
Obligations of any series or maturity within a series are to be redeemed, the particular Obligations to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Obligations of such
series or maturity within a series which have not previously been called for redemption by prorating, as nearly as may be, the principal amount of Obligations of such series or maturity within a series to be redeemed among the Holders of such
Obligations in proportion to the aggregate principal amount of such Obligations registered in their respective names; EXCEPT that, if there shall have been previously filed with the Trustee an Act of all the Holders of such Obligations satisfactory
to the Trustee specifying the method of selecting the Obligations to be redeemed, such selection shall be made by the Trustee in accordance with the terms of such Act. 
 In any proration pursuant to this Section, the Trustee shall make such adjustments, reallocations and eliminations as it shall deem proper to the end that the principal amount of Obligations of such
series or maturity within a series so prorated shall be equal to the greater of $1,000 and the smallest authorized denomination of the Obligations of such series, or a multiple thereof, by increasing or decreasing or eliminating the amount which
would be allocable to any Holder on the basis of exact proportion by an amount not exceeding such prorated minimum. The Trustee in its discretion may determine the particular Obligations (if there is more than one) registered in the name of any
Holder which are to be redeemed, in whole or in part. 

  
 -133-

 The Trustee shall promptly notify the Company in writing of the Obligations selected for
redemption and, in the case of any Obligation selected for partial redemption, the principal amount thereof to be redeemed. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Obligations shall
relate, in the case of any Obligation redeemed or to be redeemed only in part, to the portion of the principal of such Obligation which has been or is to be redeemed. 
 Section 15.04. Notice of Redemption. 
 Except as otherwise provided in
a Supplemental Indenture, notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Obligations of such series to be redeemed, at his
address appearing in the Obligation Register. 
 Except as otherwise provided in a Supplemental Indenture, all notices of
redemption shall state: 
 A. the CUSIP number (if any) of all Obligations to be redeemed, 

B. the Redemption Date, 
 C. the Redemption Price, 
 D. the principal amount of Obligations of each series
to be redeemed, and, if less than all Outstanding Obligations of a series are to be redeemed, the identification (and, in the case of partial redemption, the respective principal amounts) of the Obligations of such series to be redeemed, 

E. that on the Redemption Date the Redemption Price of each of the Obligations to be redeemed will become due and payable and that the
interest thereon shall cease to accrue from and after said Redemption Date, 
 F. the place or places where the Obligations of
each series to be redeemed are to be surrendered for payment of the Redemption Price, which shall be the office or agency of the Company in each Place of Payment for such series, 

G. if it be the case, that such Obligations are to be redeemed by the application of certain specified Trust Moneys, 

H. if it be the case, that such redemption is to satisfy sinking fund requirements, 

I. if it be the case that the notice of redemption for such Obligations is conditional and revocable, (i) that the redemption of
such Obligations is conditional upon the Company depositing or providing, or causing to be deposited or provided, to the Trustee or the Paying Agent, by 2:00 p.m. New York City time on the redemption date, funds (which, if the Company is the Paying
Agent, shall be segregated and held in trust pursuant to Section 14.03) sufficient to 

  
 -134-

 
effect such redemption, (ii) that if such funds are not so provided, such Obligations will not be redeemed on such date and the notice of the redemption of such Obligations will be of no
force or effect, (iii) that the Company is under no obligation to deposit or provide, or cause to be deposited or provided, such funds, and (iv) that neither the Company nor the Trustee shall be liable to any Holder if the Company does not
deposit or provide, or cause to be deposited or provided, funds sufficient to effect such redemption with the result that such Obligations are not redeemed on the Redemption Date specified in such notice, and 

J. if it be the case that the notice of redemption is unconditional and irrevocable, (i) that the Trustee or the Paying Agent has on
deposit sufficient funds to effect such redemption (which, if the Company is acting as its own Paying Agent, shall be segregated and held in trust as provided in Section 14.03), and (ii) that such Obligations shall become due and payable
at the Redemption Price on the Redemption Date specified in the notice. 
 Notice of redemption of Obligations to be redeemed at
the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. 
 Section 15.05. Deposit of Redemption Price. 
 Neither the Company nor
the Trustee shall be liable to any Holder if the Company does not deposit or provide, or cause to be deposited or provided, funds sufficient to effect redemption of any Obligations with the result that such Obligations are not redeemed on the
Redemption Date specified in such notices. If such funds shall not have been so received, the Trustee shall give notice to the Holders, in the manner in which the notice of redemption was given to the Holders, that such funds were not so received.

 If, at the time notice of redemption is delivered to the Holders, the Trustee or Paying Agent has on deposit (which, if the
Company is acting as its own Paying Agent, is segregated and held in trust as provided in Section 14.03) an amount of money sufficient to pay the Redemption Price of all the Obligations which are to be redeemed on the Redemption Date, then the
notice of redemption is unconditional and irrevocable and the Obligations specified in the notice of redemption shall become due and payable at the specified Redemption Price on the specified Redemption Date. Such money shall be held in trust for
the benefit of the Persons entitled to such Redemption Price and shall not be deemed to be part of the Trust Estate or Trust Moneys. 
 Subject to the requirements of any Supplemental Indenture, the Company may determine what sinking fund requirements (if any) to apply redeemed Obligations against. 

Section 15.06. Obligations Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Obligations so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified and from and after such date (unless the Company shall default in the payment of the Redemption Price) such Obligations shall cease to bear interest. Upon surrender of any such Obligation for
redemption in accordance with said notice, such Obligation shall be paid by the Company at the Redemption Price. Installments of interest with a Stated Maturity on or prior to the Redemption Date shall be payable to the Holders of the Obligations
registered as such on the relevant Record Dates according to the terms of such Obligations and the provisions of Section 3.08. 

  
 -135-

 If any Obligation called for redemption shall not be so paid upon surrender thereof for
redemption or as otherwise provided under Section 15.07 in lieu of surrender, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Obligation. 

Section 15.07. Obligations Redeemed in Part. 
 Unless otherwise provided in any Supplemental Indenture, any Obligation which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the Trustee
shall authenticate and deliver to the Holder of such Obligation, without service charge, a new Obligation or Obligations of the same series and maturity of any authorized denomination or denominations as requested by such Holder in aggregate
principal amount equal to and in exchange for the unredeemed portion of the principal of the Obligation so surrendered. 
 In
lieu of surrender under the preceding paragraph, payment of the Redemption Price of a portion of any Obligation held in the Book-Entry System may be made directly to the Holder thereof without surrender thereof, if there shall have been delivered to
the Trustee either (1) a written agreement between the Company and such Holder and, if such Holder is a nominee, the Person for whom such Holder is a nominee, that payment shall be so made and that such Holder will not sell, transfer or
otherwise dispose of such Obligation unless prior to delivery thereof such Holder shall present such Obligation to the Trustee for notation thereon of the portion of the principal thereof redeemed or shall surrender such Obligation in exchange for a
new Obligation or Obligations for the unredeemed balance of the principal of the surrendered Obligation or (ii) a certificate of the Company that such an agreement has been entered into and remains in force. 

Section 15.08. Applicability of Sections 15.08 through 15.10. 

The provisions of Sections 15.08 through 15.10 shall be applicable to any sinking fund for the retirement of Obligations of a series
except as otherwise specified as contemplated by Section 3.02 for Obligations of such series. 
 The minimum amount of any
sinking fund payment provided for by the terms of Obligations of any series is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of Obligations of any
series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Obligations of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 15.09. Each
sinking fund payment shall be applied to the redemption of Obligations of any series as provided for by the terms of Obligations of such series. 

  
 -136-

 Section 15.09. Satisfaction of Sinking Fund Payments with Obligations.

 The Company (1) may deliver Outstanding Obligations of a series (other than any previously called for redemption) and
(2) may apply, as a credit, Obligations of a series which have been redeemed either at the election of the Company pursuant to the terms of such Obligations or through the application of permitted optional sinking fund payments pursuant to the
terms of such Obligations, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Obligations of such series required to be made pursuant to the terms of such Obligations as provided for by the terms of such
series; PROVIDED that such Obligations have not been previously so credited. Such Obligations shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Obligations for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 

Section 15.10. Redemption of Obligations for Sinking Fund. 

Not less than 60 days prior to each sinking fund payment date for any series of Obligations, the Company will deliver to the Trustee an
Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Obligations of that series pursuant to Section 15.09 and will also deliver to the Trustee any Obligations to be so delivered. Not less than 30 days before each such sinking fund payment date
the Trustee shall select the Obligations to be redeemed upon such sinking fund payment date in the manner specified in Section 15.03 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 15.04. Such notice having been duly given, the redemption of such Obligations shall be made upon the terms and in the manner stated in Sections 15.06 and 15.07. 

ARTICLE XVI 
 CONTROL OF PLEDGED SECURITIES 
 Section 16.01. Pledged Securities
Deposited with Trustee. 
 Any Stock and certificates representing the same and any obligations and indebtedness and
evidences thereof and any other securities which are at the time deposited with the Trustee or required to be deposited and pledged with the Trustee, except Undesignated Qualifying Securities and Designated Qualifying Securities, are herein
sometimes collectively called the “Pledged Securities.” 
 As and when any Pledged Securities shall come into
the possession of the Company or under its control, the Company shall forthwith deposit and pledge the same with the Trustee, together with such proper instruments of assignment and transfer as the Trustee may reasonably require, which shall include
express authority to the Trustee to vote any Stock included therein to the extent herein provided or permitted and to cause such authority to be recorded in the entry of transfer of such Stock on the books of the entity issuing the same. 

  
 -137-

 The Trustee shall not be obliged at any time to accept any Pledged Securities or to cause or
to permit a transfer thereof to be made to it, if, in the opinion of the Trustee, such action would subject it to the risk of any liability or expense, unless the Trustee shall be indemnified to its satisfaction for so doing. 

The Trustee shall not be under any duty to examine into or pass upon the validity or genuineness of any of the Pledged Securities. The
Trustee shall be entitled to assume that any Pledged Securities are genuine and valid and what they purport to be and that any endorsements or assignments thereof are genuine and valid. 

Section 16.02. Form of Holding. 
 The Trustee may hold any Pledged Securities in bearer form or in the name of the Trustee or any nominee or nominees of the Trustee or (unless an Event of Default exists or the Holders of a majority in
principal amount of the Obligations then Outstanding otherwise direct) in the name of the Company or any nominee or nominees of the Company, endorsed or assigned in blank or in favor of the Trustee. The Trustee may deliver any of the Pledged
Securities to the Company for a period of not more than 21 days or to the issuer thereof for the purpose of making exchanges or registrations or transfers or for such other purposes in furtherance of this trust as the Trustee may deem advisable.

 Section 16.03. Right of Trustee to Preserve Issuers; Directors’ Qualifying Shares. 

The Trustee may do whatever in its judgment may be necessary for the purpose of preserving or extending the legal existence of any Person
whose Stock is included in the Pledged Securities, but (subject to Section 10.01) it shall be under no duty to take any action in respect thereof. Upon Company Request stating that the Company has no shares for the purpose under its control
other than shares held hereunder, the Trustee shall transfer or permit the Company to transfer as many shares of stock as may be necessary to qualify the requisite number of persons to act as directors of or in any other official relation to the
corporation issuing such shares; PROVIDED, HOWEVER, that no such transfer of the stock of any Pledged Subsidiary shall be made which would change the status of the issuing corporation as a Pledged Subsidiary. In every such case the
Trustee may make such arrangements as it shall deem necessary for the protection of the trust hereunder in respect of the shares so transferred. While such shares remain so transferred they shall not be deemed to be Pledged Securities, but when such
shares are no longer needed for such qualification purposes they shall immediately be redeposited and repledged and thereupon again become Pledged Securities. 
 Section 16.04. Income Before Event of Default. 
 Unless an Event of
Default exists, the Company from time to time shall be entitled to receive and collect for its own use all interest paid on any Pledged Security (other than any such interest which shall have been collected or paid out of the proceeds of any sale or
condemnation or expropriation of any property covered by a mortgage or other lien securing such Pledged Security) and all dividends on any Pledged Security which are paid in cash out of the net profits or earned surplus of the issuing corporation
accrued since the date of deposit and pledge of such Pledged Security with the Trustee hereunder. The Trustee from time to time shall execute and 

  
 -138-

 
deliver upon Company Request suitable orders in favor of the Company or its nominee for the payment of such interest and cash dividends and shall deliver upon Company Request any and all coupons
held by the Trustee representing such interest as the date of the maturity thereof approaches. The Trustee shall likewise upon Company request pay over all sums which are received or collected by it as such interest or cash dividends. Until actually
paid, all rights to such interest or cash dividends shall remain subject to the lien hereof. 
 The Trustee shall be entitled
(subject to Section 10.01) to assume that any cash dividend received by it on any Pledged Security is paid out of the net profits or earned surplus of the issuing corporation accrued since the date of deposit and pledge of such Pledged Security
with the Trustee hereunder and that any interest has not been collected or paid out of the proceeds of any such sale or condemnation or expiration, unless and until notified in writing to the contrary by any Holder or the Company or the person
making such payment, in which event the Trustee may (subject to Section 10.01) accept an Officers’ Certificate stating any pertinent facts in connection with any such dividend or interest as conclusive evidence of such facts. 

Section 16.05. Income After Event of Default. 
 If an Event of Default exists, in addition to the other remedies herein provided, the Trustee shall collect and receive all interest and dividends on Pledged Securities and may in its discretion, and if
requested by Holders of a majority in principal amount of the Obligations then Outstanding shall, cancel and revoke all interest and dividend orders in favor of the Company or its nominee. All money so received by the Trustee which, in the absence
of an Event of Default, would be receivable by the Company under Section 16.04, shall be applied in accordance with Section 9.07. 
 In every such case, after all Events of Default have been cured, the right of the Company to receive and collect interest and dividends, and the duty of the Trustee with respect thereto, under
Section 16.04, shall revive and continue; and the Trustee shall pay over upon Company Request any such interest or dividends received by it which, in the absence of an Event of Default, would be receivable by the Company under
Section 16.04 and then remain unexpended in its hands. 
 Section 16.06. Principal and Other Payments.

 In case any sum shall be paid on account of: 
 A. the principal of (or premium, if any, on) any Pledged Security, or 
 B. any
dividend upon any Pledged Security other than a cash dividend paid out of the net profits or earned surplus of the issuing corporation accrued since the date of deposit and pledge of such Pledged Security with the Trustee hereunder, or 

C. the liquidation or dissolution or reduction of capital of the corporation issuing any Pledged Security, or 

  
 -139-

 D. interest on any Pledged Security which shall have been collected or paid out of the
proceeds of any sale or condemnation or expropriation of any property covered by a mortgage or other lien securing such Pledged Security, 
 or
in case any other distribution (including stock dividends but excluding any dividend excluded by Subsection (B)) shall be made in respect of any Pledged Security, such sum or other distribution shall be paid or delivered to the Trustee to be held as
a part of the Trust Estate. 
 In case the Company or the Trustee shall receive rights to subscribe to additional securities in
respect of any Pledged Securities, the Company may exercise or (subject to Section 16.08) sell such rights in its discretion; PROVIDED, HOWEVER, that (i) all securities acquired by exercise of such rights shall forthwith be
deposited and pledged with the Trustee hereunder, (ii) all net proceeds from the sale of any such rights shall forthwith be paid to the Trustee, (iii) if the Company shall not have elected to exercise or sell such rights by the fifth
business day prior to the expiration thereof, it shall give the Trustee notice thereof and the Trustee shall forthwith take action with respect thereto as and to the extent directed to do so by Holders of a majority in principal amount of the
Obligations then Outstanding or, in the event that Section 16.08 is applicable, may exercise such rights and take action with respect thereto as and to the extent directed to do so by Holders of a majority in principal amount of the Obligations
then Outstanding (iv) if an Event of Default exists, the Trustee shall be entitled at any time in its discretion to exercise or sell such rights; provided that the Trustee shall have no Obligation to take any action under this Section unless
the Holders have provided the Trustee with adequate funds to take such actions. 
 Section 16.07. Voting.

 Unless an Event of Default exists, the Company shall have the right to vote and give consents with respect to all Pledged
Securities and from time to time, in case any Pledged Securities have been transferred into the name of the Trustee or its nominee or nominees, the Trustee, upon Company Request, shall execute and deliver or cause to be executed and delivered to the
Company or its nominee appropriate powers of attorney or proxies to vote such Pledged Securities or to execute a waiver or consent with respect thereto, for such purpose or purposes as may be specified in such request; PROVIDED,
HOWEVER, that such right of the Company shall not include (and every such power of attorney or proxy shall be limited, either generally or specifically, to provide in effect that the powers thereby conferred do not include) any power to vote
for or to authorize or consent to any act or thing inconsistent with or in avoidance of the Company’s obligations under this Indenture. 
 If an Event of Default exists, the Trustee may in its discretion, and if requested by the Holders of a majority in principal amount of the Obligations then Outstanding shall, revoke all such powers of
attorney and proxies and the Trustee may in its discretion vote and exercise, or cause the nominee or nominees of the Trustee to vote and exercise, all the powers of an owner with respect to any Pledged Securities. In so voting and exercising the
powers of an owner with respect to any Pledged Securities, the Trustee shall not be required to attend any meeting of security holders, but the Trustee may vote or act by power of attorney or proxy and such power of attorney or proxy may be granted
to any person selected by the Trustee, including an officer of the Company. The Trustee may so vote and exercise the powers of an owner with respect to any 

  
 -140-

 
Pledged Securities for any purpose or purposes which the Trustee, in its discretion, shall deem advisable and in the interest of the Holders, whether or not such action may involve a change in
the character of any Pledged Security or in the corporate identity or business of the issuer thereof or in the proportionate interest or voting power represented by such security. In every such case, after all Events of Default have been cured, the
right of the Company to vote and give consents with respect to the Pledged Securities, and the duty of the Trustee to execute powers of attorney and proxies as hereinabove provided, shall revive and continue. 

Section 16.08. Limitations on Issuance of Voting Stock or Grant Membership Interests of Pledged Subsidiaries. 

The Company will not permit any Pledged Subsidiary to issue any additional shares of Voting Stock, other than stock dividends, unless
simultaneously there shall be made effective provision that certificates for all such additional Voting Stock, forthwith upon the issue thereof, will be deposited and pledged with the Trustee; PROVIDED, HOWEVER, that, if the holders of
any stock of such Pledged Subsidiary not then included in the Pledged Securities shall have a preemptive right to subscribe for and purchase their pro rata share of such additional shares of Voting Stock, then such part of such additional shares as
shall be actually subscribed for and purchased by such stockholders pursuant to such preemptive right may be issued to them and need not be deposited and pledged with the Trustee. 

Section 16.09. Increase, Reduction or Reclassification of Stock; Dissolution; Consolidation, Etc. 

Except as otherwise provided in Article XIV or this Article, the capital stock of any corporation whose shares are included in the Pledged
Securities may be increased (subject to Section 16.08) or reduced or reclassified (other than a reclassification resulting in the creation of a preferred stock of any Pledged Subsidiary or a reclassification reducing the proportionate voting
power of any Pledged Securities in any corporation) and any such corporation may be dissolved; PROVIDED, HOWEVER, that effective provision shall (to the extent the Company has any control of such matters) be made that, in the case of
any such increase, whether by stock dividend or otherwise (subject to Section 16.08), certificates for such part of each class of additional stock as shall be proportionate to the part of the entire issued and outstanding capital stock of such
class of such corporation previously deposited and pledged with the Trustee and, in the case of any such reclassification, any distribution in connection therewith shall be deposited and pledged with the Trustee and that, in the case of any such
reduction, there shall continue to be deposited and pledged with the Trustee certificates for not less than the same proportion of such class of capital stock deposited and pledged with the Trustee before such reduction. The Trustee may make any
exchange, substitution, cancellation or surrender of certificates of stock held by it for the purpose of such increase, reduction, reclassification or dissolution. Prior to any such cancellation or surrender of stock certificates for the purpose of
dissolution, the share, if any, of all the assets of the corporation so dissolved which is distributable in respect of the Pledged Securities (excluding Excepted Property) shall be subjected to the lien of this Indenture. The Trustee shall be
entitled to receive and shall (subject to Section 10.01) be fully protected in relying upon an Officers’ Certificate as to the amount of the share of the assets of any corporation dissolved as aforesaid which is so distributable to the
holder of such Pledged Securities. 

  
 -141-

 The deposit and pledge with the Trustee at any time of any shares of stock of any
corporation shall not prevent any one or more of the following transactions: 
 A. subject to the provisions of Articles XII and
XIV, the merger or consolidation of any Pledged Subsidiary into or with the Company or the conveyance or transfer of all or any of the assets of any Pledged Subsidiary to the Company, or 

B. the merger or consolidation of any corporation, any of whose shares may be Pledged Securities, into or with any other corporation
other than the Company, or the conveyance or transfer of all or any of the assets of any corporation, any of whose shares may be Pledged Securities, to any other corporation other than the Company; PROVIDED, HOWEVER, that no such
action involving a Pledged Subsidiary shall be taken unless the corporation resulting from such consolidation, or into which such merger shall be made, or which shall have acquired the assets of a Pledged Subsidiary, shall thereupon be a Pledged
Wholly-Owned Subsidiary. 
 Section 16.10. Enforcement. 

In case default shall be made in the payment of the principal of or interest on any Pledged Security or in the due performance of any
covenant contained in any Pledged Security or the instrument securing the same, then and in any such case (without prejudice, however, to any right to claim a default under this Indenture or to assert any right consequent upon such default) the
Trustee, upon Company Request, shall, upon receipt of indemnity to its satisfaction and adequate assurance of payment or reimbursement of its costs and expenses (including legal fees and expenses), cause, or join with other owners of like securities
in causing, such proceedings as may be directed by the Company to be instituted and prosecuted to collect such principal and interest or enforce the performance of such covenant. If an Event of Default exists, the Trustee may, and upon the written
request of the Holders of a majority in principal amount of the Obligations then Outstanding shall, upon receipt of indemnity to its satisfaction and adequate assurance of payment or reimbursement of its costs and expenses (including its legal fees
and expenses), institute such proceedings without Company Request. 
 Section 16.11. Acquisition of Property of Issuers
of Pledged Securities. 
 In case, at any time, all or any of the property of any corporation, any of whose securities are at
the time Pledged Securities, shall be sold upon insolvency or foreclosure or otherwise, then and in such event, if the property of such corporation or the property sold can be acquired by crediting on any of the Pledged Securities any sum accruing
or to be received thereon out of the proceeds of such property, the Trustee in its discretion may, if requested by Company Request or by the Holders of a majority in principal amount of the Obligations then Outstanding and provided by the Company or
such Holders with the amount of any cash necessary therefor shall purchase such property or cause the same to be purchased, in the name of the Company or a purchasing trustee or trustees as the Trustee may determine, and shall use or permit the
Company or such purchasing trustees to use such Pledged Securities so far as necessary to make payment for such property. In case of any such purchase the Company shall take such steps as it may deem proper to cause the property so purchased to be
vested in the Company subject to the lien of this Indenture, or in some other corporation organized or to be organized with power to 

  
 -142-

 
acquire and manage such property, or partly in the Company and partly in such other corporation, as the Company may deem advisable, PROVIDED that all debt of such corporation with a
maturity more than one year from date of issuance (except such, if any, as shall represent a lien existing upon the property at the time it was acquired) and certificates for all the capital stock (except directors’ qualifying shares) of such
corporation shall be deposited and pledged with the Trustee. In case the property so sold shall not be purchased in the manner hereinabove in this Section provided, the Trustee shall receive the proceeds of sale accruing on and apportioned to such
Pledged Securities and such proceeds shall be held and paid over or applied by the Trustee as provided in Article VII. 

Section 16.12. Reorganization. 
 Upon receipt of a Company Request and receipt of indemnity to its satisfaction and adequate assurance of payment or reimbursement of its costs and expenses (including its legal fees and expenses), the
Trustee shall join in any plan of voluntary or involuntary reorganization or readjustment or rearrangement in respect of any Pledged Securities and may accept or authorize the acceptance of new securities issued in exchange therefor under any such
plan. If an Event of Default exists, the Trustee shall be entitled to take such steps without Company Consent. 
 Any new
securities so issued shall be deposited and pledged with the Trustee under this Indenture. If the Trustee does not join in such plan or reorganization or readjustment or rearrangement, the Trustee shall receive any moneys accruing on or apportioned
to such Pledged Securities and such moneys shall be held and paid over or applied by the Trustee as provided in Article Seven. 

Section 16.13. Renewal and Refunding. 
 Nothing contained in this Article shall prevent: 
 A. the renewal or extension,
without impairment of lien or security, at the same or at a lower or higher rate of interest, of any of the obligations or indebtedness of any corporation included in the Pledged Securities, or 

B. the issue in substitution for any such obligations or indebtedness of other obligations or indebtedness of such corporation for
equivalent amounts and of substantially equal or superior rank as to security, if any; 
 PROVIDED, HOWEVER, that every such
obligation or indebtedness as so renewed or extended shall continue to be subject to the lien hereof and every substituted obligation or indebtedness and the evidence thereof shall be deposited and pledged with the Trustee. 

Except as otherwise provided in Article XIV, unless an Event of Default exists, the Trustee upon receipt of a Company Request shall, and
if an Event of Default exists the Trustee may without such Company Request, consent to any such renewal, extension or substitution. 

  
 -143-

 Section 16.14. Expenses. 

On demand of the Trustee, the Company forthwith will pay or satisfactorily provide for all expenses incurred by the Trustee under this
Article, including all expenditures made to acquire the ownership and title to any property which the Trustee shall purchase or shall cause or authorize to be purchased under this Article and the Trustee shall not, under any circumstances, have any
obligation to take action under thus Article unless such amounts have been paid to, or provided for, the Trustee as it may determine in its sole and absolute discretion. Without impairment of or prejudice to any of its rights hereunder by reason of
any default of the Company, the Trustee in its discretion may advance all such expenses and other sums required or may procure such advances to be made by others. The Company will repay all such advances, with interest thereon at the rate of
10% per annum, and for all such advances the Trustee shall be secured by a lien on the Trust Estate prior to the Obligations. For the repayment of all such advances the Trustee shall have the right to use and apply any Trust Moneys held by it
under Article VII as part of the Trust Estate. 
 Section 16.15. Opinion of Counsel. 

The Trustee shall be entitled, before taking any action under this Article, to receive an Opinion of Counsel stating the legal effect of
any transaction relating to the Pledged Securities and the steps necessary to be taken to consummate the same and stating also that such action is in compliance with the provisions hereof and will not materially adversely impair the security of the
Holders hereunder in contravention of the provisions hereof. Such Opinion of Counsel shall be full protection to the Trustee for any action taken or omitted to be taken by it in reliance thereon. 

ARTICLE XVII 
 QUALIFYING SECURITIES; QUALIFYING SECURITIES INDENTURES 

Section 17.01. Registration and Ownership of Designated Qualifying Securities. 

Designated Qualifying Securities delivered to the Trustee pursuant to Sections 5.05, 5.06, 5.08, 6.02, 7.04 and 17.03 shall be registered
in the name of the Trustee (with its trustee capacity so delineated) or its nominee and shall be held by the Trustee as part of the Trust Estate, subject to the provisions of this Indenture, for the benefit of the Holders of all Obligations from
time to time Outstanding, and the Company shall have no interest therein. The Trustee shall be entitled to exercise all rights of security holders under each Qualifying Securities Indenture except as otherwise provided in this Article or in
Article IX. 
 Section 17.02. Payments on Qualifying Securities. 

Unless an Event of Default shall have occurred and be continuing: 

A. Any payment of principal of Designated Qualifying Securities shall be applied by the Trustee to the payment of the principal of the
Obligations which were authenticated and delivered on the basis of such Qualifying Securities which is then due, and, to the extent of such application, the obligation of the Company to make such payment in respect of such Obligations shall be
deemed to have been satisfied and discharged; 

  
 -144-

 B. If, at the time of any such payment of principal of Designated Qualifying Securities, the
principal then due in respect of the Obligations which were authenticated and delivered on the basis of such Qualifying Securities, if any, shall be less than such payment, the excess of such payment shall constitute Trust Moneys and shall be held
by the Trustee as part of the Trust Estate, to be withdrawn, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Article VII. Any Outstanding Obligations, which were authenticated and
delivered on the basis of Designated Qualifying Securities which have been paid, shall be thereafter deemed not to have been authenticated and delivered on the basis of Designated Qualifying Securities; 

C. Any payment of premium or interest on Designated Qualifying Securities shall be applied by the Trustee to the payment of premium or
interest, as the case may be, on the Obligations which were authenticated and delivered on the basis of such Designated Qualifying Securities, if any, which is then due, and, to the extent of such application, the obligation of the Company to make
such payment in respect of such Obligations shall be deemed to have been satisfied and discharged; 
 D. If, at the time of any
such payment of premium or interest on Designated Qualifying Securities, the premium or interest, as the case may be, then due in respect of the Obligations which were authenticated and delivered on the basis of such Designated Qualifying
Securities, if any, shall be less than such payment, the excess of such payment shall be remitted to the Company upon receipt by the Trustee of a Company Request requesting the same; and 

E. Any payment to the Trustee of principal of, or premium or interest on, any Undesignated Qualifying Securities shall be remitted to the
Company upon receipt by the Trustee of a Company Request requesting the same. 
 Section 17.03. Surrender or
Redesignation of Designated Qualifying Securities. 
 A. At the time any Obligations of any series, which shall have been
authenticated and delivered upon the basis of the issuance and delivery to the Trustee of Designated Qualifying Securities, shall cease to be Outstanding (other than as a result of the application of the proceeds of the payment or redemption of such
Designated Qualifying Securities), the Company, by notice to the Trustee, may designate an equal principal amount of such Designated Qualifying Securities as Undesignated Qualifying Securities. Upon Company Request, the Trustee shall surrender for
cancellation any Undesignated Qualifying Securities. 
 B. Upon Company Request and receipt of the opinions required by
Subsections (F) and (G) of Section 5.05, the Trustee shall surrender for cancellation any Designated Qualifying Securities specified in such request in exchange for an equal principal amount of substitute Qualifying Securities, which
substitute Qualifying Securities shall comply with Section 5.05(C) (except that, if the Designated Qualifying Securities to be surrendered were delivered other than as the basis for the authentication and delivery of Additional Obligations, the
maturity date or dates for such substitute Qualifying Securities may be as determined by the Company) and which 

  
 -145-

 
the Company shall designate as the basis for such surrender. Upon receipt of a notice of an event of default under a Qualifying Securities Indenture, upon Company Request the Trustee shall
surrender for cancellation all Undesignated Qualifying Securities issued under such Qualifying Securities Indenture. 
 C. Upon
receipt of a notice of a meeting of bondholders under a Qualifying Securities Indenture, the Trustee shall surrender for cancellation all Undesignated Qualifying Securities issued under such Qualifying Securities Indenture. Upon delivery to the
Trustee of (i) the relevant documents specified in Subsections (B) through (G), inclusive, of Section 5.02 for delivery whenever requesting the use of Bondable Additions as the basis for the surrender or redesignation of Designated
Qualifying Securities, or (ii) the relevant documents and Obligations specified in Subsections (B), (D) and (E) of Section 5.03 for the delivery to the Trustee whenever requesting the use of retired or defeased Obligations or
payments on Obligations as the basis for the surrender or redesignation of Designated Qualifying Securities, in each case with such omissions and variations as are appropriate in view of the fact that the Application involves the surrender or
redesignation of Designated Qualifying Securities and not the authentication and delivery of Additional Obligations, and in each case together with an Opinion of Counsel stating that all conditions precedent provided for in this Indenture relating
to such surrender or redesignation of Qualifying Securities have been complied with, the Trustee shall, upon Company Request surrender to the Company or redesignate Designated Qualifying Securities as Undesignated Qualifying Securities in a
principal amount equal to the principal amount of the Obligations that could have been issued on the basis thereof. Upon receipt by the Trustee of the documents specified in this Section, all Obligations then Outstanding which were authenticated and
delivered on the basis of such surrendered or redesignated Qualifying Securities shall thereafter be deemed not to have been authenticated and delivered on the basis of Designated Qualifying Securities. 

Section 17.04. No Transfer of Qualifying Securities. 
 The Trustee shall, as a holder of Qualifying Securities Outstanding under each Qualifying Securities Indenture, attend such meeting or meetings of bondholders under such Qualifying Securities Indenture,
or, at its option, deliver its proxy in connection therewith, as relates to matters with respect to which it is entitled to vote or consent. So long as no Event of Default shall have occurred and be continuing, either at any such meeting or
meetings, or otherwise when the consent of the holders of the Qualifying Securities Outstanding under any Qualifying Securities Indenture is sought without a meeting, the Trustee shall vote as holder of such Qualifying Securities, or shall consent
with respect thereto. The Trustee shall vote all Qualifying Securities Outstanding under such Qualifying Securities Indenture then held by it, or consent with respect thereto, as the Trustee reasonably believes will be in the best interests of the
Holders; PROVIDED, HOWEVER, that the Trustee shall not so vote in favor of, or so consent to, any amendment or modification of a Qualifying Securities Indenture which, if it were an amendment or modification of this Indenture, would require
the consent of Holders, without the prior consent, obtained in the manner prescribed in Section 13.02, of Holders of Securities which would be required under Section 13.02 for such an amendment or modification of this Indenture.

  
 -146-

 Section 17.05. Reorganization. 

Upon receipt of a Company Request and receipt of indemnity to its satisfaction and adequate assurance of payment or reimbursement of its
costs and expenses (including its legal fees and expenses), the Trustee shall join in any plan of voluntary or involuntary reorganization or readjustment or rearrangement in respect of any Qualifying Securities and may accept or authorize the
acceptance of new securities issued in exchange therefor under any such plan. If an Event of Default exists, the Trustee shall be entitled to take such steps without Company Consent. 

Any new securities so issued shall be deposited and pledged with the Trustee under this Indenture. If the Trustee does not join in such
plan or reorganization or readjustment or rearrangement, the Trustee shall receive any moneys accruing on or apportioned to such Qualifying Securities and such moneys shall be held and paid over or applied by the Trustee as provided in Article VII.

 This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same
instrument.
