 Certain terms used in this Agreement are defined in Section 6 hereof. 
 The Addendum to this Agreement, and any Annexes or Exhibits described in this Agreement or such Addendum, are hereby incorporated into this Agreement and
made fully a part hereof. 
 1.    Offers, Sales and Resales of Notes. 

	 	 1.1
	 While (i) the Issuer has and shall have no obligation to sell the Notes to the Dealer or to permit the Dealer to arrange any sale of the Notes for the
account of the Issuer, and (ii) the Dealer has and shall have no obligation to purchase the Notes from the Issuer or to arrange any sale of the Notes for the account of the Issuer, the parties hereto agree that in any case where the Dealer
purchases Notes from the Issuer, or arranges for the sale of Notes by the Issuer, such Notes will be purchased or sold by the Dealer in reliance on the representations, warranties, covenants and agreements of the Issuer contained herein or made
pursuant hereto and on the terms and conditions and in the manner provided herein. 

  

	 	 1.2
	 So long as this Agreement shall remain in effect, and in addition to the limitations contained in Section 1.7 hereof, the Issuer shall not, without the
consent of the Dealer, offer, solicit or accept offers to purchase, or sell, any Notes except (a) in transactions with one or more dealers which may from time to time after the date hereof become dealers with respect to the Notes by executing
with the Issuer one or more agreements which contain provisions substantially identical to those contained in Section 1 of this Agreement, of which the Issuer hereby undertakes to provide the Dealer prompt notice or (b) in transactions
with the other dealers listed on the Addendum hereto, which are executing agreements with the Issuer which contain provisions substantially identical to Section 1 of this Agreement contemporaneously herewith. In no event shall the Issuer offer,
solicit or accept offers to purchase, or sell, any Notes directly on its own behalf in transactions with persons other than broker-dealers as specifically permitted in this Section 1.2. 

  

	 	 1.3
	 The Notes shall be in a minimum denomination of $250,000 or integral multiples of $1,000 in excess thereof, will bear such interest rates, if interest bearing,

the Private Placement Memorandum. The Notes shall not contain any provision for extension, renewal or automatic “rollover.”

	 	 1.5
	 If the Issuer and the Dealer shall agree on the terms of the purchase of any Note by the Dealer or the sale of any Note arranged by the Dealer (including, but
not limited to, agreement with respect to the date of issue, purchase price, principal amount, maturity and interest rate or interest rate index and margin (in the case of interest-bearing Notes) or discount thereof (in the case of Notes issued on a
discount basis), and appropriate compensation for the Dealer’s services hereunder) pursuant to this Agreement, the Issuer shall cause such Note to be issued and delivered in accordance with the terms of the Issuing and Paying Agency Agreement
and payment for such Note shall be made by the purchaser thereof, either directly or through the Dealer, to the Issuing and Paying Agent, for the account of the Issuer. Except as otherwise agreed, in the event that the Dealer is acting as an agent
and a purchaser shall either fail to accept delivery of or make payment for a Note on the date fixed for settlement, the Dealer shall promptly notify the Issuer, and if the Dealer has theretofore paid the Issuer for the Note, the Issuer will
promptly return such funds to the Dealer against its return of the Note to the Issuer, in the case of a certificated Note, and upon notice of such failure in the case of a book-entry Note. If such failure occurred for any reason other than default
by the Dealer, the Issuer shall reimburse the Dealer on an equitable basis for the Dealer’s loss of the use of such funds for the period such funds were credited to the Issuer’s account. 

  

	 	 1.6
	 The Dealer and the Issuer hereby establish and agree to observe the following procedures in connection with offers, sales and subsequent resales or other
transfers of the Notes: 

  

	 	 (a)
	 Offers and sales of the Notes by or through the Dealer shall be made only to: (i) investors reasonably believed by the Dealer to be Qualified Institutional
Buyers, Institutional Accredited Investors or Sophisticated Individual Accredited Investors and (ii) non-bank fiduciaries or agents that will be purchasing Notes for one or more accounts, each of which is reasonably believed by the Dealer to be
an Institutional Accredited Investor or Sophisticated Individual Accredited Investor. 

  

	 	 (b)
	 Resales and other transfers of the Notes by the holders thereof shall be made only in accordance with the restrictions in the legend described in clause
(e) below. 

  

	 	 (c)
	 No general solicitation or general advertising shall be used in connection with the offering of the Notes. Without limiting the generality of the foregoing,
without the prior written approval of the Dealer, the Issuer shall not issue any press release or place or publish any “tombstone” or other advertisement relating to the Notes. 

  

	 	 (d)
	 No sale of Notes to any one purchaser shall be for less than $250,000 principal or face amount, and no Note shall be issued in a smaller principal or face
amount. If the purchaser is a non-bank fiduciary acting on behalf of others, each person for whom such purchaser is acting must purchase at least $250,000 principal or face amount of Notes. 

  

	 	 (e)
	 Offers and sales of the Notes by the Issuer through the Dealer acting as agent for the Issuer shall be made in accordance with Rule 506 under the Securities Act,
and shall be subject to the restrictions described in the legend appearing on Exhibit A hereto. A legend substantially to the effect of such Exhibit A shall appear as part of the Private Placement Memorandum used in connection with offers and sales
of Notes hereunder, as well as on each individual certificate representing a Note and each Master Note representing book-entry Notes offered and sold pursuant to this Agreement. 

  

 n Commercial Paper Dealer Agreement 4(2) Program n 3 

	 	 (f)
	 The Dealer shall furnish or shall have furnished to each purchaser of Notes for which it has acted as the Dealer a copy of the then-current Private Placement
Memorandum unless such purchaser has previously received a copy of the Private Placement Memorandum as then in effect. The Private Placement Memorandum shall expressly state that any person to whom Notes are offered shall have an opportunity to ask
questions of, and receive information from, the Issuer and the Dealer and shall provide the names, addresses and telephone numbers of the persons from whom information regarding the Issuer may be obtained. 

  

	 	 (g)
	 The Issuer agrees, for the benefit of the Dealer and each of the holders and prospective purchasers from time to time of the Notes that, if at any time the
Issuer shall not be subject to Section 13 or 15(d) of the Exchange Act, the Issuer will furnish, upon request and at its expense, to the Dealer and to holders and prospective purchasers of Notes information required by Rule 144A(d)(4)(i) in
compliance with Rule 144A(d). 

  

	 	 (h)
	 In the event that any Note offered or to be offered by the Dealer would be ineligible for resale under Rule 144A, the Issuer shall immediately notify the Dealer
(by telephone, confirmed in writing) of such fact and shall promptly prepare and deliver to the Dealer an amendment or supplement to the Private Placement Memorandum describing the Notes that are ineligible, the reason for such ineligibility and any
other relevant information relating thereto. 

  

	 	 (i)
	 The Issuer represents that it is not currently issuing commercial paper in the United States market in reliance upon the exemption provided by
Section 3(a)(3) of the Securities Act. The Issuer agrees that, if it shall issue commercial paper after the date hereof in reliance upon such exemption (a) the proceeds from the sale of the Notes will be segregated from the proceeds of the
sale of any such commercial paper by being placed in a separate account; (b) the Issuer will institute appropriate corporate procedures to ensure that the offers and sales of notes issued by the Issuer pursuant to the Section 3(a)(3)
exemption are not integrated with offerings and sales of Notes hereunder; and (c) the Issuer will comply with each of the requirements of Section 3(a)(3) of the Securities Act in selling commercial paper or other short-term debt securities
other than the Notes in the United States. 

  

	 	 1.7
	 The Issuer hereby represents and warrants to the Dealer, in connection with offers, sales and resales of Notes, as follows: 

  

	 	 (a)
	 The Issuer hereby confirms to the Dealer that (except as permitted by Section 1.6(i)) within the preceding six months neither the Issuer nor any person
other than the Dealer or the other dealers referred to in Section 1.2 hereof acting on behalf of the Issuer has offered or sold any Notes, or any substantially similar security of the Issuer (including, without limitation, medium-term notes
issued by the Issuer), to, or solicited offers to buy any such security from, any person other than the Dealer or the other dealers referred to in Section 1.2 hereof. The Issuer also agrees that (except as permitted by Section 1.6(i)), as
long as the Notes are being offered for sale by the Dealer and the other dealers referred to in Section 1.2 hereof as contemplated hereby and until at least six months after the offer of Notes hereunder has been terminated, neither the Issuer
nor any person other than the Dealer or the other dealers referred to in Section 1.2 hereof (except as contemplated by Section 1.2 hereof) will offer the Notes or any substantially similar security of the Issuer for sale to, or solicit
offers to buy any such security from, any person other than the Dealer or the other dealers referred to in Section 

  

 n Commercial Paper Dealer Agreement 4(2) Program n 4 

	 	  
	 1.2 hereof, it being understood that such agreement is made with a view to bringing the offer and sale of the Notes within the exemption provided by
Section 4(2) of the Securities Act and Rule 506 thereunder and shall survive any termination of this Agreement. The Issuer hereby represents and warrants that it has not taken or omitted to take, and will not take or omit to take, any action
that would cause the offering and sale of Notes hereunder to be integrated with any other offering of securities, whether such offering is made by the Issuer or some other party or parties. 

  

	 	 (b)
	 The Issuer represents and agrees that the proceeds of the sale of the Notes are not currently contemplated to be used for the purpose of buying, carrying or
trading securities within the meaning of Regulation T and the interpretations thereunder by the Board of Governors of the Federal Reserve System. In the event that the Issuer determines to use such proceeds for the purpose of buying, carrying or
trading securities, whether in connection with an acquisition of another company or otherwise, the Issuer shall give the Dealer at least five business days’ prior written notice to that effect. The Issuer shall also give the Dealer prompt
notice of the actual date that it commences to purchase securities with the proceeds of the Notes. Thereafter, in the event that the Dealer purchases Notes as principal and does not resell such Notes on the day of such purchase, to the extent
necessary to comply with Regulation T and the interpretations thereunder, the Dealer will sell such Notes either (i) only to offerees it reasonably believes to be Qualified Institutional Buyers or to Qualified Institutional Buyers it reasonably
believes are acting for other Qualified Institutional Buyers, in each case in accordance with Rule 144A or (ii) in a manner which would not cause a violation of Regulation T and the interpretations thereunder. 

 2.    Representations and Warranties of Issuer. 
 The Issuer represents and warrants that: 
  

	 	 2.1
	 The Issuer is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has all the

	 	 2.3

upon any of the properties or assets of the Issuer, or (ii) violate or result in a breach or a default under any of the terms of the Issuer’s charter documents or by-laws, any contract or instrument to which the Issuer is a party or by
which it or its property is bound, or any law or regulation, or any order, writ, injunction or decree of any court or government instrumentality, to which the Issuer is subject or by which it or its property is bound, which breach or default might

 Model Opinion of Counsel to XTO Energy Inc. 
 [Date] 
 [ Name and Address of Dealer]

  
 Ladies and Gentlemen: 

We have acted as counsel to
                            , a
                     corporation (the “Issuer”), in connection with the proposed offering and sale by the Issuer in the United
States of commercial paper in the form of short-term promissory notes (the “Notes”). 
 In our capacity as such counsel, we have
examined a specimen form of Note, an executed copy of the Commercial Paper Dealer Agreement dated
                            ,
             (the “Agreement”) between the Issuer and
                             (the “Dealer”), and the Issuing and Paying Agency Agreement
dated             ,              (the “Issuing and Paying Agency Agreement”) between the Issuer and
            , as issuing and paying agent (the “Issuing and Paying Agent”) as well as originals, or copies certified or otherwise identified to our satisfaction, of such
other records and documents as we have deemed necessary as a basis for the opinions expressed below. In such examination, we have assumed the genuineness of all documents submitted to us as originals, and the conformity to the originals of all
documents submitted to us as copies. 
 Capitalized terms used herein without definition are used as defined in the
Agreement. 
 Based upon the foregoing, it is our opinion that: 
  

	 	 1.
	 The Issuer is a corporation duly organized, validly existing and in good standing under the laws of the state of
                     and has all the requisite corporate power and authority to execute, deliver and perform its obligations under the Notes,
the Agreement and the Issuing and Paying Agency Agreement. 

  

	 	 2.
	 Each of the Agreement and the Issuing and Paying Agency Agreement has been duly authorized, executed and delivered by the Issuer and constitutes a legal, valid
and binding obligation of the Issuer enforceable against the Issuer in accordance with its terms subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, and subject, as to enforceability, to general
principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law), and except as rights under the Agreement to indemnity and contribution may be limited by federal or state laws. 

  

	 	 3.
	 The Notes have been duly authorized, and when issued as provided in the Issuing and Paying Agency Agreement, will be duly and validly issued and will constitute
legal, valid and binding obligations of the Issuer enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, and subject, as to
enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law). 

  

 n Commercial Paper Dealer Agreement 4(2) Program n 15 

	 	 4.
	 The issuance and sale of Notes under the circumstances contemplated by the Agreement and the Issuing and Paying Agency Agreement do not require registration of
the Notes under the Securities Act of 1933, as amended, pursuant to the exemption from registration contained in Section 4(2) thereof [and Regulation D thereunder], and do not require compliance with any provision of the Trust Indenture Act of
1939, as amended; and the Notes will rank at least pari passu with all other unsecured and unsubordinated indebtedness of the Issuer. 

  

	 	 5.
	 No consent or action of, or filing or registration with, any governmental or public regulatory body or authority, including the Securities and Exchange
Commission, is required to authorize, or is otherwise required in connection with the execution, delivery or performance of, the Agreement, the Notes or the Issuing and Paying Agency Agreement, except as may be required by the securities or Blue Sky
laws of the various states in connection with the offer and sale of the Notes. 

  

	 	 6.
	 Neither the execution and delivery of the Agreement and the Issuing and Paying Agency Agreement, nor the issuance of the Notes in accordance with the Issuing and
Paying Agency Agreement, nor the fulfillment of or compliance with the terms and provisions of either thereof by the Issuer, will (i) result in the creation or imposition of any mortgage, lien, charge or encumbrance of any nature whatsoever
upon any of the properties or assets of the Issuer, or (ii) violate or result in a breach or default under any of the terms of the Issuer’s charter documents or by-laws, any contract or instrument to which the Issuer is a party or by which
it or its property is bound, or any law or regulation, or any order, writ, injunction or decree of any court or government instrumentality, to which the Issuer is subject or by which it or its property is bound. 

  

	 	 7.
	 There is no litigation or governmental proceeding pending, or to the knowledge of the Issuer threatened, against or affecting the Issuer or any of its
subsidiaries which might result in a material adverse change in the condition (financial or otherwise), operations or business prospects of the Issuer or the ability of the Issuer to perform its obligations under the Agreement, the Notes or the
Issuing and Paying Agency Agreement except as described in the Private Placement Memorandum. 

  

	 	 8.
	 The Issuer is not an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 

 This opinion may be delivered to the Issuing and Paying Agent, each holder from time to time of Notes and any nationally recognized rating agency (in
connection with the rating of the Notes), each of which may rely on this opinion to the same extent as if such opinion were addressed to it. 
 Very truly yours,

 Exhibit B 
 Further Provisions Relating to Indemnification 
  

	 (a)
	 The indemnifying party under Section 5.1 or 5.2, as the case may be, agrees to reimburse each Indemnitee for all reasonable expenses (including reasonable
fees and disbursements of external counsel) as they are incurred by it in connection with investigating or defending any loss, claim, damage, liability or action in respect of which indemnification may be sought under Section 5 of the Agreement
(whether or not it is a party to any such proceedings). 

  

	 (b)
	 Promptly after receipt by an Indemnitee of notice of the existence of a Claim, such Indemnitee will, if a claim for indemnification in respect thereof is to be
made against the Issuer, notify the Issuer in writing of the existence thereof; provided that (i) the omission so to notify the Issuer will not relieve the Issuer from any liability which it may have hereunder unless and except to the extent it
did not otherwise learn of such Claim and such failure materially prejudices the Issuer, and (ii) the omission so to notify the Issuer will not relieve it from liability which it may have to an Indemnitee otherwise than on account of this
indemnity agreement. In case any such Claim is made against any Indemnitee and it notifies the Issuer of the existence thereof, the Issuer will be entitled to participate therein, and to the extent that it may elect by written notice delivered to
the Indemnitee, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnitee; provided that if the defendants in any such Claim include both the Indemnitee and the Issuer, and the Indemnitee shall have been advised by
counsel that there may be legal defenses available to it which are different from or additional to those available to the Issuer, the Issuer shall not have the right to direct the defense of such Claim on behalf of such Indemnitee, and the
Indemnitee shall have the right to select separate counsel to assert such legal defenses on behalf of such Indemnitee. Upon receipt of notice from the Issuer to such Indemnitee of the Issuer’s election so to assume the defense of such Claim and
approval by the Indemnitee of counsel (which shall not be unreasonably withheld),, the Issuer will not be liable to such Indemnitee for expenses incurred thereafter by the Indemnitee in connection with the defense thereof (other than reasonable
costs of investigation) unless (i) the Indemnitee shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the
Issuer shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel in the jurisdiction in which any Claim is brought), approved by the Dealer, representing the Indemnitee who is party to such Claim),
(ii) the Issuer shall not have employed counsel reasonably satisfactory to the Indemnitee to represent the Indemnitee within a reasonable time after notice of existence of the Claim or (iii) the Issuer has authorized in writing the
employment of counsel for the Indemnitee. The indemnity, reimbursement and contribution obligations of the Issuer hereunder shall be in addition to any other liability the Issuer may otherwise have to an Indemnitee and shall be binding upon and
inure to the benefit of any successors, assigns, heirs and personal representatives of the Issuer and any Indemnitee. The Issuer agrees that without the Dealer’s prior written consent (which shall not be unreasonably withheld), it will not
settle, compromise or consent to the entry of any judgment in any Claim in respect of which indemnification may be sought under the indemnification provision of the Agreement (whether or not the Dealer or any other Indemnitee is an actual or
potential party to such Claim), unless such settlement, compromise or consent (i) includes an unconditional release of each Indemnitee from all liability arising out of such Claim and (ii) does not include a statement as to or an admission
of fault, culpability or failure to act, by or on behalf of any Indemnitee. The Issuer shall 

  

 n Commercial Paper Dealer Agreement 4(2) Program n 18 

	  
	 not be liable for any settlement effected without its written consent, which consent shall not be unreasonably withheld. 

 Exhibit C 
 Statement of Terms for
Interest – Bearing Commercial Paper Notes of [Name of Issuer] 
 THE PROVISIONS SET FORTH BELOW ARE QUALIFIED TO THE EXTENT
APPLICABLE BY THE TRANSACTION SPECIFIC [PRICING] [PRIVATE PLACEMENT MEMORANDUM] SUPPLEMENT (THE “SUPPLEMENT”) (IF ANY) SENT TO EACH PURCHASER AT THE TIME OF THE TRANSACTION. 
  

	 	 1.
	 General. (a) The obligations of the Issuer to which these terms apply (each a “Note”) are represented by one or more Master Notes (each, a
“Master Note”) issued in the name of (or of a nominee for) The Depository Trust Company (“DTC”), which Master Note includes the terms and provisions for the Issuer’s Interest-Bearing Commercial Paper Notes that are set forth
in this Statement of Terms, since this Statement of Terms constitutes an integral part of the Underlying Records as defined and referred to in the Master Note. 

  

	 	  
	 (b) “Business Day” means any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions are authorized
or required by law, executive order or regulation to be closed in New York City and, with respect to LIBOR Notes (as defined below) is also a London Business Day. “London Business Day” means, a day, other than a Saturday or Sunday, on
which dealings in deposits in U.S. dollars are transacted in the London interbank market. 

  

	 	 2.
	 Interest. (a) Each Note will bear interest at a fixed rate (a “Fixed Rate Note”) or at a floating rate (a “Floating Rate Note”).

  

	 	  
	 (b) The Supplement sent to each holder of such Note will describe the following terms: (i) whether such Note is a Fixed Rate Note or a Floating Rate Note
and whether such Note is an Original Issue Discount Note (as defined below); (ii) the date on which such Note will be issued (the “Issue Date”); (iii) the Stated Maturity Date (as defined below); (iv) if such Note is a Fixed
Rate Note, the rate per annum at which such Note will bear interest, if any, and the Interest Payment Dates; (v) if such Note is a Floating Rate Note, the Base Rate, the Index Maturity, the Interest Reset Dates, the Interest Payment Dates and
the Spread and/or Spread Multiplier, if any (all as defined below), and any other terms relating to the particular method of calculating the interest rate for such Note; and (vi) any other terms applicable specifically to such Note.
“Original Issue Discount Note” means a Note which has a stated redemption price at the Stated Maturity Date that exceeds its Issue Price by more than a specified de minimis amount and which the Supplement indicates will be an
“Original Issue Discount Note”. 

  

	 	  
	 (c) Each Fixed Rate Note will bear interest from its Issue Date at the rate per annum specified in the Supplement until the principal amount thereof is paid or
made available for payment. Interest on each Fixed Rate Note will be payable on the dates specified in the Supplement (each an “Interest Payment Date” for a Fixed Rate Note) and on the Maturity Date (as defined below). Interest on Fixed
Rate Notes will be computed on the basis of a 360-day year of twelve 30-day months. 

  

 n Commercial Paper Dealer Agreement 4(2) Program n 19 

	 	  
	 If any Interest Payment Date or the Maturity Date of a Fixed Rate Note falls on a day that is not a Business Day, the required payment of principal, premium, if
any, and/or interest will be payable on the next succeeding Business Day, and no additional interest will accrue in respect of the payment made on that next succeeding Business Day. 

  

	 	  
	 (d) The interest rate on each Floating Rate Note for each Interest Reset Period (as defined below) will be determined by reference to an interest rate basis (a
“Base Rate”) plus or minus a number of basis points (one basis point equals one-hundredth of a percentage point) (the “Spread”), if any, and/or multiplied by a certain percentage (the “Spread Multiplier”), if any, until
the principal thereof is paid or made available for payment. The Supplement will designate which of the following Base Rates is applicable to the related Floating Rate Note: (a) the CD Rate (a “CD Rate Note”), (b) the Commercial
Paper Rate (a “Commercial Paper Rate Note”), (c) the Federal Funds Rate (a “Federal Funds Rate Note”), (d) LIBOR (a “LIBOR Note”), (e) the Prime Rate (a “Prime Rate Note”), (f) the Treasury
Rate (a “Treasury Rate Note”) or (g) such other Base Rate as may be specified in such Supplement. 

  

	 	  
	 The rate of interest on each Floating Rate Note will be reset daily, weekly, monthly, quarterly or semi-annually (the “Interest Reset Period”). The
date or dates on which interest will be reset (each an “Interest Reset Date”) will be, unless otherwise specified in the Supplement, in the case of Floating Rate Notes which reset daily, each Business Day, in the case of Floating Rate
Notes (other than Treasury Rate Notes) that reset weekly, the Wednesday of each week; in the case of Treasury Rate Notes that reset weekly, the Tuesday of each week; in the case of Floating Rate Notes that reset monthly, the third Wednesday of each
month; in the case of Floating Rate Notes that reset quarterly, the third Wednesday of March, June, September and December; and in the case of Floating Rate Notes that reset semiannually, the third Wednesday of the two months specified in the
Supplement. If any Interest Reset Date for any Floating Rate Note is not a Business Day, such Interest Reset Date will be postponed to the next day that is a Business Day, except that in the case of a LIBOR Note, if such Business Day is in the next
succeeding calendar month, such Interest Reset Date shall be the immediately preceding Business Day. Interest on each Floating Rate Note will be payable monthly, quarterly or semiannually (the “Interest Payment Period”) and on the Maturity
Date. Unless otherwise specified in the Supplement, and except as provided below, the date or dates on which interest will be payable (each an “Interest Payment Date” for a Floating Rate Note) will be, in the case of Floating Rate Notes
with a monthly Interest Payment Period, on the third Wednesday of each month; in the case of Floating Rate Notes with a quarterly Interest Payment Period, on the third Wednesday of March, June, September and December; and in the case of Floating
Rate Notes with a semiannual Interest Payment Period, on the third Wednesday of the two months specified in the Supplement. In addition, the Maturity Date will also be an Interest Payment Date. 

  

	 	  
	 If any Interest Payment Date for any Floating Rate Note (other than an Interest Payment Date occurring on the Maturity Date) would otherwise be a day that is not
a Business Day, such Interest Payment Date shall be postponed to the next day that is a Business Day, except that in the case of a LIBOR Note, if such Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the
immediately preceding Business Day. If the Maturity Date of a Floating Rate Note falls on a day that is not a Business Day, the payment of principal and interest will be made on the next succeeding Business Day, and no interest on such payment shall
accrue for the period from and after such maturity. 

  

 n Commercial Paper Dealer Agreement 4(2) Program n 20 

 Interest payments on each Interest Payment Date for Floating Rate Notes will include
accrued interest from and including the Issue Date or from and including the last date in respect of which interest has been paid, as the case may be, to, but excluding, such Interest Payment Date. On the Maturity Date, the interest payable on a
Floating Rate Note will include interest accrued to, but excluding, the Maturity Date. Accrued interest will be calculated by multiplying the principal amount of a Floating Rate Note by an accrued interest factor. This accrued interest factor will
be computed by adding the interest factors calculated for each day in the period for which accrued interest is being calculated. The interest factor (expressed as a decimal) for each such day will be computed by dividing the interest rate applicable
to such day by 360, in the cases where the Base Rate is the CD Rate, Commercial Paper Rate, Federal Funds Rate, LIBOR or Prime Rate, or by the actual number of days in the year, in the case where the Base Rate is the Treasury Rate. The interest rate
in effect on each day will be (i) if such day is an Interest Reset Date, the interest rate with respect to the Interest Determination Date (as defined below) pertaining to such Interest Reset Date, or (ii) if such day is not an Interest
Reset Date, the interest rate with respect to the Interest Determination Date pertaining to the next preceding Interest Reset Date, subject in either case to any adjustment by a Spread and/or a Spread Multiplier. 
 The “Interest Determination Date” where the Base Rate is the CD Rate or the Commercial Paper Rate will be the second Business
Day next preceding an Interest Reset Date. The Interest Determination Date where the Base Rate is the Federal Funds Rate or the Prime Rate will be the Business Day next preceding an Interest Reset Date. The Interest Determination Date where the Base
Rate is LIBOR will be the second London Business Day next preceding an Interest Reset Date. The Interest Determination Date where the Base Rate is the Treasury Rate will be the day of the week in which such Interest Reset Date falls when Treasury
Bills are normally auctioned. Treasury Bills are normally sold at auction on Monday of each week, unless that day is a legal holiday, in which case the auction is held on the following Tuesday or the preceding Friday. If an auction is so held on the
preceding Friday, such Friday will be the Interest Determination Date pertaining to the Interest Reset Date occurring in the next succeeding week. 
 The “Index Maturity” is the period to maturity of the instrument or obligation from which the applicable Base Rate is calculated. 
 The “Calculation Date,” where applicable, shall be the earlier of (i) the tenth calendar day following the applicable Interest Determination Date or (ii) the Business Day
preceding the applicable Interest Payment Date or Maturity Date. 
 All times referred to herein reflect New York City time,
unless otherwise specified. 
 The Issuer shall specify in writing to the Issuing and Paying Agent which party will be the
calculation agent (the “Calculation Agent”) with respect to the Floating Rate Notes. The Calculation Agent will provide the interest rate then in effect and, if determined, the interest rate which will become effective on the next Interest
Reset Date with respect to such Floating Rate Note to the Issuing and Paying Agent as soon as the interest rate with respect to such Floating Rate Note has been determined and as soon as practicable after any change in such interest rate.

 All percentages resulting from any calculation on Floating Rate Notes will be rounded to the nearest one
hundred-thousandth of a percentage point, with five-one millionths of a percentage point rounded upwards. For example, 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655). 
  

 n Commercial Paper Dealer Agreement 4(2) Program n 21 

 All dollar amounts used in or resulting from any calculation on Floating Rate Notes will
be rounded, in the case of U.S. dollars, to the nearest cent or, in the case of a foreign currency, to the nearest unit (with one-half cent or unit being rounded upwards). 
 CD Rate Notes 
 “CD Rate” means the rate on any
Interest Determination Date for negotiable certificates of deposit having the Index Maturity as published by the Board of Governors of the Federal Reserve System (the “FRB”) in “Statistical Release H.15(519), Selected Interest
Rates” or any successor publication of the FRB (“H.15(519)”) under the heading “CDs (Secondary Market)”. 
 If the above rate is not published in H.15(519) by 3:00 p.m. on the Calculation Date, the CD Rate will be the rate on such Interest Determination Date set forth in the daily update of H.15(519), available through the world wide website of
the FRB at http://www.federalreserve.gov/releases/h15/Update, or any successor site or publication or other recognized electronic source used for the purpose of displaying the applicable rate (“H.15 Daily Update”) under the caption
“CDs (Secondary Market)”. 
 If such rate is not published in either H.15(519) or H.15 Daily Update by 3:00 p.m. on
the Calculation Date, the Calculation Agent will determine the CD Rate to be the arithmetic mean of the secondary market offered rates as of 10:00 a.m. on such Interest Determination Date of three leading nonbank dealers1 in negotiable U.S. dollar certificates of deposit in New York City selected by the Calculation Agent for negotiable U.S. dollar
certificates of deposit of major United States money center banks of the highest credit standing in the market for negotiable certificates of deposit with a remaining maturity closest to the Index Maturity in the denomination of $5,000,000.

 If the dealers selected by the Calculation Agent are not quoting as set forth above, the CD Rate will remain the CD Rate
then in effect on such Interest Determination Date. 
 Commercial Paper Rate Notes 
 “Commercial Paper Rate” means the Money Market Yield (calculated as described below) of the rate on any Interest Determination
Date for commercial paper having the Index Maturity, as published in H.15(519) under the heading “Commercial Paper-Nonfinancial”. 
 If the above rate is not published in H.15(519) by 3:00 p.m. on the Calculation Date, then the Commercial Paper Rate will be the Money Market Yield of the rate on such Interest Determination Date for commercial paper
of the Index Maturity as published in H.15 Daily Update under the heading “Commercial Paper-Nonfinancial”. 
 If by
3:00 p.m. on such Calculation Date such rate is not published in either H.15(519) or H.15 Daily Update, then the Calculation Agent will determine the Commercial Paper Rate to be the Money Market Yield of the arithmetic mean of the offered rates as
of 11:00 a.m. on such Interest Determination Date of three leading dealers of U.S. dollar commercial paper in New York City selected by the Calculation Agent for commercial paper of the Index Maturity placed for an industrial issuer whose bond
rating is “AA,” or the equivalent, from a nationally recognized statistical rating organization. 
  
 1    Such nonbank dealers referred to in this Statement of Terms may include affiliates of the Dealer. 
  

 n Commercial Paper Dealer Agreement 4(2) Program n 22 

 If the dealers selected by the Calculation Agent are not quoting as mentioned above, the
Commercial Paper Rate with respect to such Interest Determination Date will remain the Commercial Paper Rate then in effect on such Interest Determination Date. 
 “Money Market Yield” will be a yield calculated in accordance with the following formula: 
  

					
		 	       D x 360        
  
	 	
	 Money Market Yield =
	 	 	 x 100

		 	   360 - (D x M)
	 	

 where “D” refers to the applicable per annum rate for commercial paper
quoted on a bank discount basis and expressed as a decimal and “M” refers to the actual number of days in the interest period for which interest is being calculated. 
 Federal Funds Rate Notes 
 “Federal Funds Rate” means
the rate on any Interest Determination Date for federal funds as published in H.15(519) under the heading “Federal Funds (Effective)” and displayed on Moneyline Telerate (or any successor service) on page 120 (or any other page as may
replace the specified page on that service) (“Telerate Page 120”). 
 If the above rate does not appear on Telerate
Page 120 or is not so published by 3:00 p.m. on the Calculation Date, the Federal Funds Rate will be the rate on such Interest Determination Date as published in H.15 Daily Update under the heading “Federal Funds/(Effective)”. 

If such rate is not published as described above by 3:00 p.m. on the Calculation Date, the Calculation Agent will determine the
Federal Funds Rate to be the arithmetic mean of the rates for the last transaction in overnight U.S. dollar federal funds arranged by each of three leading brokers of Federal Funds transactions in New York City selected by the Calculation Agent
prior to 9:00 a.m. on such Interest Determination Date. 
 If the brokers selected by the Calculation Agent are not quoting
as mentioned above, the Federal Funds Rate will remain the Federal Funds Rate then in effect on such Interest Determination Date. 
 LIBOR
Notes 
 The London Interbank offered rate (“LIBOR”) means, with respect to any Interest Determination Date, the
rate for deposits in U.S. dollars having the Index Maturity that appears on the Designated LIBOR Page as of 11:00 a.m., London time, on such Interest Determination Date. 
 If no rate appears, LIBOR will be determined on the basis of the rates at approximately 11:00 a.m., London time, on such Interest Determination Date at which deposits in U.S. dollars are offered
to prime banks in the London interbank market by four major banks in such market selected by the Calculation Agent for a term equal to the Index Maturity and in principal amount equal to an amount that in the Calculation Agent’s judgment is
representative for a single transaction in U.S. dollars in such market at such time (a “Representative Amount”). The Calculation Agent will request the principal London office of each of such banks to provide a quotation of its rate. If at
least two such quotations are provided, LIBOR will be the arithmetic mean of such quotations. If fewer than two quotations are provided, LIBOR for such interest period will be the arithmetic mean of the rates 
  

 n Commercial Paper Dealer Agreement 4(2) Program n 23 

 quoted at approximately 11:00 a.m., in New York City, on such Interest Determination Date
by three major banks in New York City, selected by the Calculation Agent, for loans in U.S. dollars to leading European banks, for a term equal to the Index Maturity and in a Representative Amount; provided, however, that if fewer than three banks
so selected by the Calculation Agent are providing such quotations, the then existing LIBOR rate will remain in effect for such Interest Payment Period. 
 “Designated LIBOR Page” means the display designated as page “3750” on Moneyline Telerate (or such other page as may replace the 3750 page on that service or such other service or services as may
be nominated by the British Bankers’ Association for the purposes of displaying London interbank offered rates for U.S. dollar deposits). 
 Prime Rate Notes 
 “Prime Rate” means the rate on any Interest Determination Date as published in
H.15(519) under the heading “Bank Prime Loan”. 
 If the above rate is not published in H.15(519) prior to 3:00
p.m. on the Calculation Date, then the Prime Rate will be the rate on such Interest Determination Date as published in H.15 Daily Update opposite the caption “Bank Prime Loan”. 
 If the rate is not published prior to 3:00 p.m. on the Calculation Date in either H.15(519) or H.15 Daily Update, then the Calculation
Agent will determine the Prime Rate to be the arithmetic mean of the rates of interest publicly announced by each bank that appears on the Reuters Screen US PRIME1 Page (as defined below) as such bank’s prime rate or base lending rate as of
11:00 a.m., on that Interest Determination Date. 
 If fewer than four such rates referred to above are so published by 3:00
p.m. on the Calculation Date, the Calculation Agent will determine the Prime Rate to be the arithmetic mean of the prime rates or base lending rates quoted on the basis of the actual number of days in the year divided by 360 as of the close of
business on such Interest Determination Date by three major banks in New York City selected by the Calculation Agent. 
 If
the banks selected are not quoting as mentioned above, the Prime Rate will remain the Prime Rate in effect on such Interest Determination Date. 
 “Reuters Screen US PRIME1 Page” means the display designated as page “US PRIME1” on the Reuters Monitor Money Rates Service (or such other page as may replace the US PRIME1 page on that service for
the purpose of displaying prime rates or base lending rates of major United States banks).

 (1) the rate from the auction held on the Interest Determination Date (the “Auction”) of direct obligations of the United States (“Treasury Bills”) having the Index Maturity
specified in the Supplement under the caption “INVESTMENT RATE” on the display on Moneyline Telerate (or any successor service) on page 56 (or any other page as may replace that page on that service) (“Telerate 
  

 n Commercial Paper Dealer Agreement 4(2) Program n 24 

 Page 56”) or page 57 (or any other page as may replace that page on that service)
(“Telerate Page 57”), or 
 (2) if the rate referred to in clause (1) is not so published by 3:00 p.m. on the
related Calculation Date, the Bond Equivalent Yield (as defined below) of the rate for the applicable Treasury Bills as published in H.15 Daily Update, under the caption “U.S. Government Securities/Treasury Bills/Auction High”, or

 (3) if the rate referred to in clause (2) is not so published by 3:00 p.m. on the related Calculation Date, the Bond
Equivalent Yield of the auction rate of the applicable Treasury Bills as announced by the United States Department of the Treasury, or 
 (4) if the rate referred to in clause (3) is not so announced by the United States Department of the Treasury, or if the Auction is not held, the Bond Equivalent Yield of the rate on the particular Interest
Determination Date of the applicable Treasury Bills as published in H.15(519) under the caption “U.S. Government Securities/Treasury Bills/Secondary Market”, or 
 (5) if the rate referred to in clause (4) not so published by 3:00 p.m. on the related Calculation Date, the rate on the particular Interest Determination Date of the applicable Treasury
Bills as published in H.15 Daily Update, under the caption “U.S. Government Securities/Treasury Bills/Secondary Market”, or 
 (6) if the rate referred to in clause (5) is not so published by 3:00 p.m. on the related Calculation Date, the rate on the particular Interest Determination Date calculated by the Calculation Agent as the Bond
Equivalent Yield of the arithmetic mean of the secondary market bid rates, as of approximately 3:30 p.m. on that Interest Determination Date, of three primary United States government securities dealers selected by the Calculation Agent, for the
issue of Treasury Bills with a remaining maturity closest to the Index Maturity specified in the Supplement, or 
 (7) if the
dealers so selected by the Calculation Agent are not quoting as mentioned in clause (6), the Treasury Rate in effect on the particular Interest Determination Date. 
 “Bond Equivalent Yield” means a yield (expressed as a percentage) calculated in accordance with the following
formula: 
  

					
		 	       D x N        

 
	 	
	 Bond Equivalent Yield =
	 	 	 x 100

		 	   360 - (D x M)
	 	

 where “D” refers to the applicable per annum rate for Treasury Bills
quoted on a bank discount basis and expressed as a decimal, “N” refers to 365 or 366, as the case may be, and “M” refers to the actual number of days in the applicable Interest Reset Period. 
  

	 	 3.
	 Final Maturity. The Stated Maturity Date for any Note will be the date so specified in the Supplement, which shall be no later than 397 days from the date
of issuance. On its Stated Maturity Date, or any date prior to the Stated Maturity Date on which the particular Note becomes due and payable by the declaration of acceleration, each such date being referred to as a Maturity Date, the

  

 n Commercial Paper Dealer Agreement 4(2) Program n 25 

 principal amount of each Note, together with accrued and unpaid interest thereon, will be
immediately due and payable. 
  

	 	 4.
	 Events of Default. The occurrence of any of the following shall constitute an “Event of Default” with respect to a Note: (i) default in any
payment of principal of or interest on such Note (including on a redemption thereof); (ii) the Issuer makes any compromise arrangement with its creditors generally including the entering into any form of moratorium with its creditors generally;
(iii) a court having jurisdiction shall enter a decree or order for relief in respect of the Issuer in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or there shall be appointed
a receiver, administrator, liquidator, custodian, trustee or sequestrator (or similar officer) with respect to the whole or substantially the whole of the assets of the Issuer and any such decree, order or appointment is not removed, discharged or
withdrawn within 60 days thereafter; or (iv) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an
involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, administrator, liquidator, assignee, custodian, trustee or sequestrator (or similar official), with respect to the whole or substantially the
whole of the assets of the Issuer or make any general assignment for the benefit of creditors. Upon the occurrence of an Event of Default, the principal of each obligation evidenced by such Note (together with interest accrued and unpaid thereon)
shall become, without any notice or demand, immediately due and payable. 2 

  

	 	 5.
	 Obligation Absolute. No provision of the Issuing and Paying Agency Agreement under which the Notes are issued shall alter or impair the obligation of the
Issuer, which is absolute and unconditional, to pay the principal of and interest on each Note at the times, place and rate, and in the coin or currency, herein prescribed. 

  

	 	 6.
	 Supplement. Any term contained in the Supplement shall supercede any conflicting term contained herein. 

 2  Unlike single payment notes, where a default arises only at the stated maturity, interest-bearing notes with multiple payment
dates should contain a default provision 
       permitting acceleration of the maturity if the Issuer defaults
on an interest payment.

 n Commercial Paper Dealer Agreement 4(2) Program n 27ISSUING AND PAYING AGENCY AGREEMENT

 EXHIBIT 10.2 
  
 ISSUING AND PAYING AGENCY AGREEMENT 
 This Agreement, dated as of October 27, 2006, is by and between XTO Energy Inc. (the “Issuer”) and JPMorgan Chase Bank, National Association (“JPMorgan”). 
  

	 1.
	 APPOINTMENT AND ACCEPTANCE 

 The Issuer hereby appoints JPMorgan as its issuing and paying agent in connection with the issuance and payment of certain short-term promissory notes of the Issuer (the “Notes”), as further described
herein, and JPMorgan agrees to act as such agent upon the terms and conditions contained in this Agreement. 
  

	 2.
	 COMMERCIAL PAPER PROGRAMS 

 The Issuer may establish one or more commercial paper programs under this Agreement by delivering to JPMorgan a completed program schedule (the “Program Schedule”), with respect to each such
program. JPMorgan has given the Issuer a copy of the current form of Program Schedule and the Issuer shall complete and return its first Program Schedule to JPMorgan prior to or simultaneously with the execution of this Agreement. In the event that
any of the information provided in, or attached to, a Program Schedule shall change, the Issuer shall promptly inform JPMorgan of such change in writing. 
  

	 3.
	 NOTES  

 All Notes issued by the Issuer under this Agreement shall be short-term promissory notes, exempt from the registration requirements of the Securities Act of 1933, as amended, as indicated on the Program Schedules, and from applicable state
securities laws. The Notes may be placed by dealers (the “Dealers”) pursuant to Section 4 hereof. Notes shall be issued in either certificated or book-entry form. 
  

	 4.
	 AUTHORIZED REPRESENTATIVES 

 The Issuer shall deliver to JPMorgan a duly adopted corporate resolution from the Issuer’s Board of Directors (or other governing body) authorizing the issuance of Notes under each program established pursuant to
this Agreement and a certificate of incumbency, with specimen signatures attached, of those officers, employees and agents of the Issuer authorized to take certain actions with respect to the Notes as provided in this Agreement (each such person is
hereinafter referred to as an “Authorized Representative”). Until JPMorgan receives any subsequent incumbency certificates of the Issuer, JPMorgan shall be entitled to rely on the last incumbency certificate delivered to it for the
purpose of determining the Authorized Representatives. The Issuer represents and warrants that each Authorized Representative may appoint other officers, employees and agents of the Issuer (the “Delegates”), including without
limitation any Dealers, to issue instructions to JPMorgan under this Agreement, and take other actions on the Issuer’s behalf hereunder, provided that notice of the appointment of each Delegate is delivered to JPMorgan in writing. Each such
appointment shall remain in effect unless and until revoked by the Issuer in a written notice to JPMorgan. 
  

	 5.
	 CERTIFICATED NOTES 

 If and when the Issuer intends to issue certificated notes (“Certificated Notes”), the Issuer and JPMorgan shall agree upon the form of such Notes. Thereafter, the Issuer shall from time to time deliver to JPMorgan adequate
supplies of Certificated Notes which will be in bearer form, serially numbered, and shall be executed by the manual or facsimile signature of an Authorized Representative. JPMorgan will acknowledge receipt of any supply of Certificated Notes
received from the Issuer, noting any exceptions to the shipping manifest or transmittal letter (if any), and will hold the Certificated Notes in safekeeping for the Issuer in accordance with 

 JPMorgan’s customary practices. JPMorgan shall not have any liability to the Issuer to determine by
whom or by what means a facsimile signature may have been affixed on Certificated Notes, or to determine whether any facsimile or manual signature is genuine, if such facsimile or manual signature resembles the specimen signature attached to the
Issuer’s certificate of incumbency with respect to such Authorized Representative. Any Certificated Note bearing the manual or facsimile signature of a person who is an Authorized Representative on the date such signature was affixed shall bind
the Issuer after completion thereof by JPMorgan, notwithstanding that such person shall have ceased to hold his or her office on the date such Note is countersigned or delivered by JPMorgan. 
  

	 6.
	 BOOK-ENTRY NOTES 

 The Issuer’s book-entry notes (“Book-Entry Notes”) shall not be issued in physical form, but their aggregate face amount shall be represented by a master note (the “Master Note”) in the form of Exhibit
A executed by the Issuer pursuant to the book-entry commercial paper program of The Depository Trust Company (“DTC”). JPMorgan shall maintain the Master Note in safekeeping, in accordance with its customary practices, on behalf of
Cede & Co., the registered owner thereof and nominee of DTC. As long as Cede & Co. is the registered owner of the Master Note, the beneficial ownership interest therein shall be shown on, and the transfer of ownership thereof shall
be effected through, entries on the books maintained by DTC and the books of its direct and indirect participants. The Master Note and the Book-Entry Notes shall be subject to DTC’s rules and procedures, as amended from time to time. JPMorgan
shall not be liable or responsible for sending transaction statements of any kind to DTC’s participants or the beneficial owners of the Book-Entry Notes, or for maintaining, supervising or reviewing the records of DTC or its participants with
respect to such Notes. In connection with DTC’s program, the Issuer understands that as one of the conditions of its participation therein, it shall be necessary for the Issuer and JPMorgan to enter into a Letter of Representations, in the form
of Exhibit B hereto, and for DTC to receive and accept such Letter of Representations. In accordance with DTC’s program, JPMorgan shall obtain from the CUSIP Service Bureau a written list of CUSIP numbers for Issuer’s Book-Entry Notes, and
JPMorgan shall deliver such list to DTC. The CUSIP Service Bureau shall bill the Issuer directly for the fee or fees payable for the list of CUSIP numbers for the Issuer’s Book-Entry Notes. 
  

	 7.
	 ISSUANCE INSTRUCTIONS TO JPMORGAN; PURCHASE PAYMENTS 

 The Issuer understands that all instructions under this Agreement are to be directed to JPMorgan’s Commercial Paper Operations Department. JPMorgan shall provide the Issuer, or, if
applicable, the Issuer’s Dealers, with access to JPMorgan’s Money Market Issuance System or other electronic means (collectively, the “System”) in order that JPMorgan may receive electronic instructions for the issuance of
Notes. Electronic instructions must be transmitted in accordance with the procedures furnished by JPMorgan to the Issuer or its Dealers in connection with the System. These transmissions shall be the equivalent to the giving of a duly authorized
written and signed instruction which JPMorgan may act upon without liability. In the event that the System is inoperable at any time, an Authorized Representative or a Delegate may deliver written, telephone or facsimile instructions to JPMorgan,
which instructions shall be verified in accordance with any security procedures agreed upon by the parties. JPMorgan shall incur no liability to the Issuer in acting upon instructions believed by JPMorgan in good faith to have been given by an
Authorized Representative or a Delegate. In the event that a discrepancy exists between a telephonic instruction and a written confirmation, the telephonic instruction will be deemed the controlling and proper instruction. JPMorgan may
electronically record any conversations made pursuant to this Agreement, and the Issuer hereby consents to such recordings. All issuance instructions regarding the Notes must be received by 1:00 P.M. New York time in order for the Notes to be issued
or delivered on the same day. 
 (a)         Issuance and Purchase of
Book-Entry Notes.             Upon receipt of issuance instructions from the Issuer or its Dealers with respect to Book-Entry 
  

 2 

 Notes, JPMorgan shall transmit such instructions to DTC and direct DTC to cause
appropriate entries of the Book-Entry Notes to be made in accordance with DTC’s applicable rules, regulations and procedures for book-entry commercial paper programs. JPMorgan shall assign CUSIP numbers to the Issuer’s Book-Entry Notes to
identify the Issuer’s aggregate principal amount of outstanding Book-Entry Notes in DTC’s system, together with the aggregate unpaid interest (if any) on such Notes. Promptly following DTC’s established settlement time on each
issuance date, JPMorgan shall access DTC’s system to verify whether settlement has occurred with respect to the Issuer’s Book-Entry Notes. Prior to the close of business on such business day, JPMorgan shall deposit immediately available
funds in the amount of the proceeds due the Issuer (if any) to the Issuer’s account at JPMorgan and designated in the applicable Program Schedule (the “Account”), provided that JPMorgan has received DTC’s
confirmation that the Book-Entry Notes have settled in accordance with DTC’s applicable rules, regulations and procedures. JPMorgan shall have no liability to the Issuer whatsoever if any DTC participant purchasing a Book-Entry Note fails to
settle or delays in settling its balance with DTC or if DTC fails to perform in any respect. 
 (b)         Issuance and Purchase of Certificated Notes. Upon receipt of issuance instructions with respect to Certificated Notes, JPMorgan shall: (a) complete each Certificated
Note as to principal amount, date of issue, maturity date, place of payment, and rate or amount of interest (if such Note is interest bearing) in accordance with such instructions; (b) countersign each Certificated Note; and (c) deliver
each Certificated Note in accordance with the Issuer’s instructions, except as otherwise set forth below. Whenever JPMorgan is instructed to deliver any Certificated Note by mail, JPMorgan shall strike from the Certificated Note the word
“Bearer,” insert as payee the name of the person so designated by the Issuer and effect delivery by mail to such payee or to such other person as is specified in such instructions to receive the Certificated Note. The Issuer understands
that, in accordance with the custom prevailing in the commercial paper market, delivery of Certificated Notes shall be made before the actual receipt of payment for such Notes in immediately available funds, even if the Issuer instructs JPMorgan to
deliver a Certificated Note against payment. Therefore, once JPMorgan has delivered a Certificated Note to the designated recipient, the Issuer shall bear the risk that such recipient may fail to remit payment of such Note or return such Note to
JPMorgan. Delivery of Certificated Notes shall be subject to the rules of the New York Clearing House in effect at the time of such delivery. Funds received in payment of Certificated Notes shall be credited to the Account. 
  

	 8.
	 USE OF SALES PROCEEDS IN ADVANCE OF PAYMENT 

 JPMorgan shall not be obligated to credit the Issuer’s Account unless and until payment of the purchase price of each Note is received by JPMorgan. From time to time, JPMorgan, in its sole
discretion, may permit the Issuer to have use of funds payable with respect to a Note prior to JPMorgan’s receipt of the sales proceeds of such Note. If JPMorgan makes a deposit, payment or transfer of funds on behalf of the Issuer before
JPMorgan receives payment for any Note, such deposit, payment or transfer of funds shall represent an advance by JPMorgan to the Issuer to be repaid promptly, and in any event on the same day as it is made, from the proceeds of the sale of such
Note, or by the Issuer if such proceeds are not received by JPMorgan. 
  

 3 

	 9.
	 PAYMENT OF MATURED NOTES 

 Notice that the Issuer will not redeem any Note on the relative Initial Redemption Date (as defined in the applicable Extendible Commercial Note Announcement) must be received in writing by JPMorgan by 11:00 A.M. on
such Initial Redemption Date. On any other day when a Note matures or is prepaid, the Issuer shall transmit, or cause to be transmitted, to the Account, prior to 2:00 P.M. New York time on the same day, an amount of immediately available funds
sufficient to pay the aggregate principal amount of such Note and any applicable interest due. JPMorgan shall pay the interest (if any) and principal on a Book-Entry Note to DTC in immediately available funds, which payment shall be by net
settlement of JPMorgan’s account at DTC. JPMorgan shall pay Certificated Notes upon presentment. JPMorgan shall have no obligation under the Agreement to make any payment for which there is not sufficient, available and collected funds in the
Account, and JPMorgan may, without liability to the Issuer, refuse to pay any Note that would result in an overdraft to the Account. 
  

	 10.
	 OVERDRAFTS 

 (a)        Intraday overdrafts with respect to each Account shall be subject to JPMorgan’s policies as in effect from time to time. 
 (b)        An overdraft will exist in an Account if JPMorgan, in its sole discretion,
(i) permits an advance to be made pursuant to Section 8 and, notwithstanding the provisions of Section 8, such advance is not repaid in full on the same day as it is made, or (ii) pays a Note pursuant to Section 9 in excess
of the available collected balance in such Account. Overdrafts shall be subject to JPMorgan’s established banking practices, including, without limitation, the imposition of interest, funds usage charges and administrative fees. The Issuer
shall repay any such overdraft, fees and charges no later than the next business day, together with interest on the overdraft at the rate established by JPMorgan for the Account, computed from and including the date of the overdraft to the date of
repayment. 
  

	 11.
	 NO PRIOR COURSE OF DEALING 

 No prior action or course of dealing on the part of JPMorgan with respect to advances of the purchase price or payments of matured Notes shall give rise to any claim or cause of action by the Issuer against JPMorgan
in the event that JPMorgan refuses to pay or settle any Notes for which the Issuer has not timely provided funds as required by this Agreement. 
  

	 12.
	 RETURN OF CERTIFICATED NOTES 

 JPMorgan will in due course cancel any Certificated Note presented for payment and return such Note to the Issuer. JPMorgan shall also cancel and return to the Issuer any spoiled or voided Certificated Notes. Promptly
upon written request of the Issuer or at the termination of this Agreement, JPMorgan shall destroy all blank, unissued Certificated Notes in its possession and furnish a certificate to the Issuer certifying such actions. 
  

	 13.
	 INFORMATION FURNISHED BY JPMORGAN 

 Upon the reasonable request of the Issuer, JPMorgan shall promptly provide the Issuer with information with respect to any Note issued and paid hereunder, provided, that the Issuer delivers such request in
writing and, to the extent applicable, includes the serial number or note number, principal amount, payee, date of issue, maturity date, amount of interest (if any) and place of payment of such Note. 
  

 4 

	 14.
	 REPRESENTATIONS AND WARRANTIES 

 The Issuer represents and warrants that: (i) it has the right, capacity and authority to enter into this Agreement; and (ii) it will comply with all of its obligations and duties under this Agreement. The
Issuer further represents and agrees that each Note issued and distributed upon its instruction pursuant to this Agreement shall constitute the Issuer’s representation and warranty to JPMorgan that such Note is a legal, valid and binding
obligation of the Issuer, and that such Note is being issued in a transaction which is exempt from registration under the Securities Act of 1933, as amended, and any applicable state securities law. 
  

	 15.
	 DISCLAIMERS 

 Neither JPMorgan nor its directors, officers, employees or agents shall be liable for any act or omission under this Agreement except in the case of gross negligence or willful misconduct. IN NO EVENT SHALL JPMORGAN BE LIABLE FOR SPECIAL,
INDIRECT OR CONSEQUENTIAL LOSS OR DAMAGE OF ANY KIND WHATSOEVER (INCLUDING BUT NOT LIMITED TO LOST PROFITS), EVEN IF JPMORGAN HAS BEEN ADVISED OF THE LIKELIHOOD OF SUCH LOSS OR DAMAGE AND REGARDLESS OF THE FORM OF ACTION. In no event shall JPMorgan
be considered negligent in consequence of complying with DTC’s rules, regulations and procedures. The duties and obligations of JPMorgan, its directors, officers, employees or agents shall be determined by the express provisions of this
Agreement and they shall not be liable except for the performance of such duties and obligations as are specifically set forth herein and no implied covenants shall be read into this Agreement against them. Neither JPMorgan nor its directors,
officers, employees or agents shall be required to ascertain whether any issuance or sale of any Notes (or any amendment or termination of this Agreement) has been duly authorized or is in compliance with any other agreement to which the Issuer is a
party (whether or not JPMorgan is also a party to such agreement). 
  

	 16.
	 INDEMNIFICATION 

 The Issuer agrees to indemnify, defend and hold harmless JPMorgan, its directors, officers, employees and agents (collectively, “indemnitees”) from and against any and all liabilities, claims, losses, damages, penalties, costs and
expenses (including attorneys’ fees and disbursements) suffered or incurred by or asserted or assessed against any indemnitee arising in respect of this Agreement, except in respect of any indemnitee for any such liability, claim, loss, damage,
penalty, cost or expense resulting from the gross negligence or willful misconduct of such indemnitee. This indemnity will survive the termination of this Agreement. 
  

	 17.

 ADDITIONAL CLAUSES FOR NON-U.S. ISSUERS 
  

	 32.

 The Issuer, for the benefit of JPMorgan and the holders from time to time of the Notes, hereby irrevocably appoints
                                        
                        , with offices on the date hereof located at
                                        
                                    , New York, New York
                     as its agent (the “Authorized Agent”) upon which process may be served in any Proceeding and hereby
agrees that service of process upon the Authorized Agent, by mail or delivery, shall be deemed in every respect effective service of process upon it in any such Proceeding. The Issuer agrees to take any and all action, including, but not limited to,
the execution and filing of all such documents and instruments, as may be necessary to effect and continue the appointment by it of the Authorized Agent in full force and effect so long as any of the Notes shall be outstanding. Nothing herein
contained shall, however, in any manner limit the rights of JPMorgan or the holders of the Notes to serve process in any other manner permitted by applicable law. 
  

	 33.
	 WAIVER OF IMMUNITY  

 The Issuer irrevocably waives, to the fullest extent permitted by applicable law, with respect to itself and its revenues and assets (irrespective of their use or intended use), all immunity on the grounds of
sovereign immunity or other similar grounds from (i) suit, (ii) jurisdiction of any court, (iii) relief by way of injunction or order for specific performance or for recovery of property, (iv) attachment of its assets (whether
before or after judgment) and (v) execution or enforcement of any judgment to which it or its revenues or assets might otherwise be entitled in any Proceeding. 
  

	 34.
	 WITHHOLDING TAXES 

 The Issuer represents and warrants that there is no withholding or other tax, assessment or governmental charge imposed by
                                 [insert name of country] or any political
subdivision thereof or taxing authority therein on account of the Notes, this Agreement, or any payments thereon or hereunder. The Issuer agrees that in the event that any tax, assessment or change shall hereafter become applicable, it shall
promptly notify JPMorgan in writing and further agrees that all amounts payable by it in respect of any Note or this Agreement shall be paid without set-off or counterclaim and free and clear of, and without deduction or withholding for or on
account of, any present or future tax, assessment or other governmental charge or any interest or penalty thereon (collectively, “Tax”) imposed, levied, collected, assessed or required to be deducted, withheld or paid by or for the
account of                                  [insert name of country] or any taxing
authority or political subdivision thereof or therein. If any such Tax is required by law to be withheld or deducted from any such payment, the Issuer shall pay the full amount of such Tax and pay such additional amounts as may be necessary to
ensure that the net amount actually received by the person entitled to such payment is equal to the amount such person would have received had no such Tax been withheld from such payment, provided that the Issuer shall not be required to pay
any such additional amount on account of any Tax that would not have been so imposed but for the existence of any present or former personal or business connection between the person entitled to such payment and
                     [insert name of country] other than the mere receipt of such payment or the ownership or holding of such Note.

 The obligation of the Issuer to make payment in lawful currency of the United States of America (“Dollars”) of any and all amounts due hereunder or under the Notes shall not be discharged or satisfied by any tender or any
recovery pursuant to any judgment in any currency other than Dollars, except to the extent that such tender or recovery shall result in the actual receipt by JPMorgan in New York or the holders of the Notes of the full amount of Dollars payable
hereunder or under the Notes, and shall be enforceable as an alternative or additional cause of action for the purpose of recovering in Dollars the amount, if any, by which such actual receipt shall fall short of the full amount of Dollars so paid.

		 	 Re:
	 	  
			
		 		 	  
			
		 		 	  
		 		 	[Description of Program, including reference to the provision of the Securities Act of 1933, as amended, pursuant to which Program is exempt from registration.]

 Ladies and Gentlemen: 
 This letter sets forth our understanding with respect to certain matters relating to the issuance by Issuer from time to time of notes
under its Commercial Paper program described above (the “Securities”). Issuing Agent shall act as issuing agent with respect to the Securities. Paying Agent shall act as paying agent or other such agent of Issuer with respect to the
Securities. Issuance of the Securities has been authorized pursuant to a prospectus supplement, offering circular, or other such document authorizing the issuance of the Securities dated
                                        
    . 
 Paying Agent has entered into a Money Market Instrument or Commercial Paper Certificate
Agreement with The Depository Trust Company (“DTC”) dated as of
                                        
        , pursuant to which Paying Agent shall act as custodian of a Master Note Certificate evidencing the Securities, when issued. Paying Agent shall amend Exhibit A to such Certificate Agreement to
include the program described above, prior to issuance of the Securities. 
  
 

 

 To induce DTC to accept the Securities as eligible for deposit at DTC and to act in
accordance with its Rules with respect to the Securities, Issuer, Issuing Agent, and Paying Agent make the following representations to DTC: 
 1. The Securities shall be evidenced by a Master Note Certificate in registered form registered in the name of DTC’s nominee, Cede & Co., and such Master Note Certificate shall represent 100% of the
principal amount of the Securities. The Master Note Certificate shall include the substance of all material provisions set forth in the DTC model Commercial Paper Master Note, a copy of which previously has been furnished to Issuing Agent and Paying
Agent, and may include additional provisions as long as they do not conflict with the material provisions set forth in the DTC model. 
 2. Issuer: (a) understands that DTC has no obligation to, and will not, communicate to its participants (“Participants”) or to any person having an interest in the Securities any information contained
in the Master Note Certificate; and (b) acknowledges that neither DTC’s Participants nor any person having an interest in the Securities shall be deemed to have notice of the provisions of the Master Note Certificate by virtue of
submission of such Certificate to DTC. 
 3. For Securities to be issued at a discount from the face value to be paid at
maturity (“Discount Securities”), Issuer or Issuing Agent has obtained from the CUSIP Service Bureau a written list of two basic six-character CUSIP numbers (each of which uniquely identifies Issuer and two years of maturity dates for the
Discount Securities to be issued under its Commercial Paper program described above). The CUSIP numbers on such list have been reserved for future assignment to issues of the Discount Securities based on the maturity year of the Discount Securities
and will be perpetually reassignable in accordance with DTC’s Procedures, including DTC’s Final Plan for DTC Money Market Programs and DTC’s Issuing/Paying Agent General Operating Procedures for Corporate Commercial Paper (the
“MMI Procedures”), a copy of which previously has been furnished to Issuing Agent and Paying Agent. 
 For
Securities to be issued at face value with interest to be paid at maturity only or periodically (“Interest Bearing Securities”), Issuer or Issuing Agent has obtained from the CUSIP Service Bureau a written list of approximately 900
nine-character numbers (the basic first six characters of which are the same and uniquely identify Issuer and the Interest Bearing Securities to be issued under its Commercial Paper program described above). The CUSIP numbers on such list have been
reserved for future assignment to issues of the Interest Bearing Securities. At any time when fewer than 100 of the CUSIP numbers on such list remain unassigned, Issuer or Issuing Agent shall promptly obtain from the CUSIP Service Bureau an
additional written list of approximately 900 such numbers. 
 4. When Securities are to be issued through DTC, Issuing Agent
shall notify Paying Agent and shall give issuance instructions to DTC in accordance with the MMI Procedures. The giving of such issuance instructions, which include delivery instructions, to DTC shall constitute: (a) a representation that the
Securities are issued in accordance with applicable law; and (b) a confirmation that the Master Note Certificate evidencing such Securities, in the form described in paragraph 1, has been issued and authenticated. 
  

 -2- 

 5. All notices and payment advises sent to DTC shall contain the CUSIP number of the
Securities. 
 6. Issuer recognizes that DTC does not in any way undertake to, and shall not have any responsibility to,
monitor or ascertain the compliance of any transactions in the Securities with the following, as amended from time to time: (a) any exemptions from registration under the Securities Act of 1933; (b) the Investment Company Act of 1940;
(c) the Employee Retirement Income Security Act of 1974; (d) the Internal Revenue Code of 1986; (e) any rules of any self-regulatory organizations (as defined under the Securities Exchange Act of 1934); or (f) any other local,
state, federal, or foreign laws or regulations thereunder. 
 7. Notwithstanding anything set forth in any document relating
to a letter of credit facility, neither DTC nor Cede & Co. shall have any obligations or responsibilities relating to the letter of credit facility, if any, unless such obligations or responsibilities are expressly set forth herein.

 8. If issuance of Securities through DTC is scheduled to take place one or more days after Issuing Agent has given
issuance instructions to DTC, Issuing Agent may cancel such issuance by giving a cancellation instruction to DTC in accordance with the MMI Procedures. 
 9. At any time that Paying Agent has Securities in its DTC accounts, it may request withdrawal of such Securities from DTC by giving a withdrawal instruction to DTC in accordance with the MMI Procedures. Upon
DTC’s acceptance of such withdrawal instruction, Paying Agent shall reduce the principal amount of the Securities evidenced by the Master Note Certificate accordingly. 
 10. In the event of any solicitation of consents from or voting by holders of the Securities, Issuer, Issuing Agent, or Paying Agent shall establish a record date for such purposes (with no
provision for revocation of consents or votes by subsequent holders) and shall send notice of such record date to DTC’s Reorganization Department, Proxy Unit no fewer than 15 calendar days in advance of such record date. If sent by telecopy,
such notice shall be directed to (212) 855-5181 or (212) 855-5182. If the party sending the notice does not receive a telecopy receipt from DTC such party shall confirm DTC’s receipt of such telecopy by telephoning
(212) 855-5187. For information regarding such notices, telephone The Depository Trust and Clearing Corporation’s Proxy hotline at (212) 855-5191. 
 11. Paying Agent may override DTC’s determination of interest and principal payment dates, in accordance with the MMI Procedures. 
 12. Notice regarding the amount of variable interest and principal payments on the Securities shall be given to DTC by Paying Agent in
accordance with the MMI Procedures. 
 13. All notices sent to DTC shall contain the CUSIP number of the Securities.

 14. Paying Agent shall confirm with DTC daily, by CUSIP number, the face value of the Securities outstanding, and Paying
Agent’s corresponding interest and principal payment obligation, in accordance with the MMI Procedures. 
  

 -3- 

 15. DTC may direct Issuer, Issuing Agent, or Paying Agent to use any other number or
address as the number or address to which notices or payments may be sent. 
 16. Payments on the Securities, including
payments in currencies other than the U.S. Dollar, shall be made by Paying Agent in accordance with the MMI Procedures. 
 17. In the event that Issuer determines that beneficial owners of the Securities shall be able to obtain certificated Securities, Issuer, Issuing Agent, or Paying Agent shall notify DTC of the availability of certificates. In such event,
Issuer, Issuing Agent, or Paying Agent shall issue, transfer, and exchange certificates in appropriate amounts, as required by DTC and others. 
 18. Issuer authorizes DTC to provide to Issuing Agent and/or Paying Agent listings of DTC Participants’ holdings, known as Security Position Reports (“SPRs”) with respect to the Assets from time to time
at the request of Issuing Agent or Paying Agent. DTC charges a fee for such SPRs. This authorization, unless revoked by Issuer, shall continue with respect to the Assets while any Assets are on deposit at DTC, until and unless Issuing Agent and/or
Paying Agent shall no longer be acting as Issuing and/or Paying Agent for Issuer. In such event, Issuer shall provide DTC with similar evidence, satisfactory to DTC, of the authorization of any successor thereto so to act. Proxy Web Services are
available at www.dtc.org. To register for or inquire about Proxy Web Services, telephone The Depository Trust and Clearing Corporation’s Proxy Hotline at (212) 855-5191. 
 19. DTC may discontinue providing its services as securities depository with respect to the Securities at any time by giving reasonable
notice to Issuer, Issuing Agent, or Paying Agent (at which time DTC will confirm with Issuer, Issuing Agent, or Paying Agent the aggregate amount of Securities outstanding by CUSIP number). Under such circumstances, at DTC’s request Issuer,
Issuing Agent, and Paying Agent shall cooperate fully with DTC by taking appropriate action to make available one or more separate certificates evidencing Securities to any Participant having Securities credited to its DTC accounts. 
 20. Nothing herein shall be deemed to require Issuing Agent or Paying Agent to advance funds on behalf of Issuer. 
 21. This Letter of Representations may be executed in any number of counterparts, each of which when so executed shall be deemed to be an
original, but all such counterparts together shall constitute but one and the same instrument. 
 22. This Letter of
Representations shall be governed by, and construed in accordance with, the laws of the State of New York, without giving effect to principles of conflicts of law. 
 23. The sender of each notice delivered to DTC pursuant to this Letter of Representations is responsible for confirming that such notice was properly received by DTC. 
 24. Issuer represents that the Securities are not securities of an issuer that is listed on the Office of Foreign Asset Control
(“OFAC”) issuer list distributed by the U.S. Department of the Treasury, or of an issuer that is incorporated in a country that is on the OFAC list of “pariah” countries. 
  

 -4- 

 25. Issuer, Issuing Agent and Paying Agent shall comply with the applicable requirements
stated in DTC’s MMI Procedures, as they may be amended from time to time. 
 26. The following riders, attached hereto,

 SCHEDULE A 
 SAMPLE OFFERING DOCUMENT LANGUAGE 
 DESCRIBING BOOK-ENTRY-ONLY ISSUANCE 
 (Prepared by DTC—bracketed material may be applicable only to certain issues) 
 1. The Depository Trust Company (“DTC”), New York, NY, will act as securities depository for the securities (the “Securities”). The Securities will be issued as
fully-registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered Security certificate will be issued for
[each issue of] the Securities, [each] in the aggregate principal amount of such issue, and will be deposited with DTC. [If, however, the aggregate principal amount of [any] issue exceeds $500 million, one certificate will be issued with respect to
each $500 million of principal amount, and an additional certificate will be issued with respect to any remaining principal amount of such issue.] 
 2. DTC, the world’s largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities
Exchange Act of 1934. DTC holds and provides asset servicing for over 2.2 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC”s
participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry
transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies,
clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC, in turn, is owned by a number of Direct Participants of DTC and Members of the
National Securities Clearing Corporation, Fixed Income Clearing Corporation, and Emerging Markets Clearing Corporation (NSCC, FICC, and EMCC, also subsidiaries of DTCC), as well as by the New York Stock Exchange, Inc., the American Stock Exchange
LLC, and the National Association of Securities Dealers, Inc. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or
maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has Standard & Poor’s highest rating: AAA. The DTC Rules applicable to its Participants are on file
with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com and www.dtc.org. 
 3. Purchases of Securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the Securities on DTC’s records. The ownership interest of each actual purchaser of each Security
(“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive
written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests
in the Securities are to be accomplished by entries 
  

 -i- 

 made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial
Owners will not receive certificates representing their ownership interests in Securities, except in the event that use of the book-entry system for the Securities is discontinued. 
 4. To facilitate subsequent transfers, all Securities deposited by Direct Participants with DTC are registered in the name of DTC’s
partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of Securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not
effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Securities; DTC’s records reflect only the identity of the Direct Participants to whose accounts such Securities are credited, which may or
may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers. 
 5. Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. [Beneficial Owners of Securities may wish to take certain steps to augment the transmission to
them of notices of significant events with respect to the Securities, such as redemptions, tenders, defaults, and proposed amendments to the Security documents. For example, Beneficial Owners of Securities may wish to ascertain that the nominee
holding the Securities for their benefit has agreed to obtain and transmit notices to Beneficial Owners. In the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of notices be
provided directly to them.] 
 [6. Redemption notices shall be sent to DTC. If less than all of the Securities within an
issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.] 
 7. Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to Securities unless authorized by a Direct Participant in accordance with DTC’s MMI Procedures. Under its
usual procedures, DTC mails an Omnibus Proxy to Issuer as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts Securities are credited
on the record date (identified in a listing attached to the Omnibus Proxy). 
 8. Redemption proceeds, distributions, and
dividend payments on the Securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of
funds and corresponding detail information from Issuer or Agent, on payable date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and
customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC, Agent, or Issuer, subject to any
statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and dividend payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of
DTC) is the responsibility of Issuer or Agent, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect
Participants. 
  

 -ii- 

 [9. A Beneficial Owner shall give notice to elect to have its Securities purchased or
tendered, through its Participant, to [Tender/Remarketing] Agent, and shall effect delivery of such Securities by causing the Direct Participant to transfer the Participant’s interest in the Securities, on DTC’s records, to
[Tender/Remarketing] Agent. The requirement for physical delivery of Securities in connection with an optional tender or a mandatory purchase will be deemed satisfied when the ownership rights in the Securities are transferred by Direct Participants
on DTC’s records and followed by a book-entry credit of tendered Securities to [Tender/Remarketing] Agent’s DTC account.] 
 10. DTC may discontinue providing its services as depository with respect to the Securities at any time by giving reasonable notice to Issuer or Agent. Under such circumstances, in the event that a successor depository is not obtained,
Security certificates are required to be printed and delivered. 
 11. Issuer may decide to discontinue use of the system of
book-entry-only transfers through DTC (or a successor securities depository). In that event, Security certificates will be printed and delivered to DTC. 
 12. The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that Issuer believes to be reliable, but Issuer takes no responsibility for the accuracy thereof.

 EXHIBIT C 
 FORM OF OPINION 
 Model Opinion of Counsel to XTO Energy Inc. 
 [Date] 
 [ Name and Address of Dealer]

  
 Ladies and Gentlemen: 

We have acted as counsel to
                            , a
                     corporation (the “Issuer”), in connection with the proposed offering and sale by the Issuer in the United
States of commercial paper in the form of short-term promissory notes (the “Notes”). 
 In our capacity as such counsel, we have
examined a specimen form of Note, an executed copy of the Commercial Paper Dealer Agreement dated
                            ,
             (the “Agreement”) between the Issuer and
                             (the “Dealer”), and the Issuing and Paying Agency Agreement
dated             ,              (the “Issuing and Paying Agency Agreement”) between the Issuer and
            , as issuing and paying agent (the “Issuing and Paying Agent”) as well as originals, or copies certified or otherwise identified to our satisfaction, of such
other records and documents as we have deemed necessary as a basis for the opinions expressed below. In such examination, we have assumed the genuineness of all documents submitted to us as originals, and the conformity to the originals of all
documents submitted to us as copies. 
 Capitalized terms used herein without definition are used as defined in the
Agreement. 
 Based upon the foregoing, it is our opinion that: 
  

	 	 1.
	 The Issuer is a corporation duly organized, validly existing and in good standing under the laws of the state of
                     and has all the requisite corporate power and authority to execute, deliver and perform its obligations under the Notes,
the Agreement and the Issuing and Paying Agency Agreement. 

  

	 	 2.
	 Each of the Agreement and the Issuing and Paying Agency Agreement has been duly authorized, executed and delivered by the Issuer and constitutes a legal, valid
and binding obligation of the Issuer enforceable against the Issuer in accordance with its terms subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, and subject, as to enforceability, to general
principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law), and except as rights under the Agreement to indemnity and contribution may be limited by federal or state laws. 

  

	 	 3.
	 The Notes have been duly authorized, and when issued as provided in the Issuing and Paying Agency Agreement, will be duly and validly issued and will constitute
legal, valid and binding obligations of the Issuer enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, and subject, as to
enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law). 

  

	 	 4.
	 The issuance and sale of Notes under the circumstances contemplated by the Agreement and the Issuing and Paying Agency Agreement do not require registration of
the Notes under the Securities Act of 1933, as amended, pursuant to the exemption from registration contained in Section 4(2) thereof [and Regulation D thereunder], and do not require compliance with any provision of the Trust Indenture Act of
1939, as amended; and the Notes will rank at least pari passu with all other unsecured and unsubordinated indebtedness of the Issuer. 

  

	 	 5.
	 No consent or action of, or filing or registration with, any governmental or public regulatory body or authority, including the Securities and Exchange
Commission, is required to authorize, or is otherwise required in connection with the execution, delivery or performance of, the Agreement, the Notes or the Issuing and Paying Agency Agreement, except as may be required by the securities or Blue Sky
laws of the various states in connection with the offer and sale of the Notes. 

  

	 	 6.
	 Neither the execution and delivery of the Agreement and the Issuing and Paying Agency Agreement, nor the issuance of the Notes in accordance with the Issuing and
Paying Agency Agreement, nor the fulfillment of or compliance with the terms and provisions of either thereof by the Issuer, will (i) result in the creation or imposition of any mortgage, lien, charge or encumbrance of any nature whatsoever
upon any of the properties or assets of the Issuer, or (ii) violate or result in a breach or default under any of the terms of the Issuer’s charter documents or by-laws, any contract or instrument to which the Issuer is a party or by which
it or its property is bound, or any law or regulation, or any order, writ, injunction or decree of any court or government instrumentality, to which the Issuer is subject or by which it or its property is bound. 

  

	 	 7.
	 There is no litigation or governmental proceeding pending, or to the knowledge of the Issuer threatened, against or affecting the Issuer or any of its
subsidiaries which might result in a material adverse change in the condition (financial or otherwise), operations or business prospects of the Issuer or the ability of the Issuer to perform its obligations under the Agreement, the Notes or the
Issuing and Paying Agency Agreement except as described in the Private Placement Memorandum. 

  

	 	 8.
	 The Issuer is not an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 

 This opinion may be delivered to the Issuing and Paying Agent, each holder from time to time of Notes and any nationally recognized rating agency (in
connection with the rating of the Notes), each of which may rely on this opinion to the same extent as if such opinion were addressed to it. 
 Very truly yours,
