 WISCONSIN ELECTRIC POWER COMPANY 

3.65% Debentures due December 15, 2042 
  

	1.	Interest. 

 Wisconsin Electric Power Company (the “Company”), a Wisconsin corporation, promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Company will
pay interest semiannually on June 15th and
December 15th of each year commencing June 15,
2013. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from December 11, 2012. Interest will be computed on the basis of a 360-day year consisting of twelve
30-day months. 
  

	2.	Method of Payment. 

 The
Company will pay interest on the Securities to the persons who are registered holders of Securities at the close of business on the record date for the next interest payment date, except as otherwise provided in the Indenture. Holders must surrender
Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. The Company may pay principal
and interest by check payable in such money. It may mail an interest check to a holder’s registered address. 
  

	3.	Securities Agents. 

Initially, U.S. Bank National Association will act as Paying Agent, Transfer Agent and Registrar. The Company may change any Paying Agent
or Transfer Agent without notice. The Company or any Affiliate may act in any such capacity. Subject to certain conditions, the Company may change the Trustee. 
  

	4.	Indenture. 

 The Company
issued the securities of this series (the “Securities”) under an Indenture dated as of December 1, 1995 (the “Indenture”) between the Company and U.S. Bank National Association (as successor to Firstar Trust Company) (the
“Trustee”). The terms of the Securities include those stated in the Indenture and in the Securities Resolution establishing the Securities and those made part of the Indenture by the Trust Indenture Act of 1939 (15 U.S. Code
Sections 77aaa-77bbbb). Securityholders are referred to the Indenture, the Securities Resolution and such Act for a statement of such terms. 
  

	5.	Redemption. 

 At any time
prior to June 15, 2042, the Securities will be redeemable in whole or in part from time to time, at the Company’s option, at a “make-whole” redemption price equal to the greater of (a) 100% of the principal amount of the
Securities being redeemed or (b) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semiannual
basis (assuming a 360-day year consisting of twelve 30-

  
 2 

 
day months) at the Treasury Rate applicable to the Securities plus 15 basis points, plus accrued interest to, but not including, the redemption date. At any time on or after June 15, 2042,
the Company may redeem the Securities, in whole or in part from time to time, at 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest to, but not including, the redemption date. 

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment
Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities being redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of
corporate debt securities of a comparable maturity to the remaining term of such Securities. 
 “Comparable Treasury
Price” means, with respect to any redemption date, (a) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (b) if the
Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Trustee after consultation with
the Company. 
 ““Reference Treasury Dealer” means each of Barclays Capital Inc., Goldman, Sachs & Co.,
Morgan Stanley & Co. LLC, a primary U.S. government securities dealer in the City of New York (a “Primary Treasury Dealer”) selected by Mitsubishi UFJ Securities (USA), Inc., their respective successors, and two other Primary
Treasury Dealers selected by the Company. If any Reference Treasury Dealer shall cease to be a Primary Treasury Dealer, the Company will select another Primary Treasury Dealer which will be substituted for that dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m.,
New York City time, on the third business day preceding such redemption date. 
 “Treasury Rate” means with respect to
any redemption date, the rate per year equal to the semiannual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for such redemption date; provided that, if the Reference Treasury Dealers shall determine that there is no such Comparable Treasury Issue, such rate per year shall be equal to the
estimated semiannual equivalent yield to maturity that a United States Treasury security having a maturity comparable to the remaining term of the Securities to be redeemed would bear, if such security were available, such estimate to be made by the
Reference Treasury Dealers on the basis of interpolation, extrapolation and other 

  
 3 

 
accepted financial practices, taking into account (a) the yields to maturity of United States Treasury securities of other maturities, (b) yields to maturity of other U.S. dollar
denominated debt securities having a maturity comparable to the remaining term of the Securities to be redeemed and (c) applicable interest rate spreads between United States Treasury securities and such other debt securities, all as of 5:00
p.m., New York City time, on the third business day preceding such redemption date. 
 Procedures for the redemption of the
Securities will be governed by Article 3 of the Indenture. 
  

	6.	Denominations, Transfer, Exchange. 

 The Securities are in registered form without coupons in denominations of $1,000 and whole multiples of $1,000. The transfer of Securities may be registered and Securities may be exchanged as provided in
the Indenture. The Transfer Agent may require a holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or the Indenture. The Transfer Agent need not exchange or register
the transfer of any Security or portion of a Security selected for redemption. Also, it need not exchange or register the transfer of any Securities for a period of 15 days before a selection of Securities to be redeemed. 

 

	7.	Persons Deemed Owners. 

The registered holder of a Security may be treated as its owner for all purposes. 

 

	8.	Amendments and Waivers. 

Subject to certain exceptions, the Indenture or the Securities may be amended with the consent of the holders of a majority in principal
amount of the securities of all series affected by the amendment. Subject to certain exceptions, a default on a series may be waived with the consent of the holders of a majority in principal amount of the series. 

Without the consent of any Securityholder, the Indenture or the Securities may be amended, among other things, to cure any ambiguity,
omission, defect or inconsistency; to provide for assumption of Company obligations to Securityholders; or to make any change that does not materially adversely affect the rights of any Securityholder. 

 

	9.	Restrictive Covenants. 

The Securities are unsecured general obligations of the Company initially limited to $250,000,000 principal amount. The Company may from
time to time without notice to, or the consent of, the holders of the Securities, create and issue further securities of the same series, equal in rank to the Securities in all respects (or in all respects except for the payment of interest accruing
prior to the issue date of the new securities or except for the first payment of interest following the issue date of the new securities) so that the new securities may be consolidated and form a single series with the Securities and have the same
terms as to status, redemption or otherwise as the Securities. The Indenture does not limit other unsecured debt. Section 4.07 of the Indenture, which if applicable limits certain mortgages and other liens, will apply with respect to the
Securities. The limitations are subject to a number of important qualifications and exceptions. 

  
 4 

	10.	Successors. 

 When a
successor assumes all the obligations of the Company under the Securities and the Indenture, the Company will be released from those obligations. 
  

	11.	Defeasance Prior to Redemption or Maturity. 

 Subject to certain conditions, the Company at any time may terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government
Obligations for the payment of principal and interest on the Securities to redemption or maturity. U.S. Government Obligations are securities backed by the full faith and credit of the United States of America which are not callable at the
issuer’s option or certificates representing an ownership interest in such Obligations. 
  

	12.	Defaults and Remedies. 

An Event of Default includes: default for 60 days in payment of interest on the Securities; default in payment of principal on the
Securities; default for 60 days in the payment of any sinking fund obligation with respect to the Securities; default by the Company for a specified period after notice to it in the performance of any of its other agreements applicable to the
Securities; certain events of bankruptcy or insolvency; and any other Event of Default provided for in the series. If an Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the Securities may
declare the principal of all the Securities to be due and payable immediately. 
 Securityholders may not enforce the Indenture
or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice
is in their interests. The Company must furnish an annual compliance certificate to the Trustee. 
  

	13.	Trustee Dealings with Company. 

 U.S. Bank National Association, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates,
and may otherwise deal with those persons, as if it were not Trustee. 

  
 5 

	14.	No Recourse Against Others. 

 A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation. Each Securityholder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 

 

	15.	Authentication. 

 This
Security shall not be valid until authenticated by a manual signature of the Registrar. 
  

	16.	Abbreviations. 

 Customary
abbreviations may be used in the name of a Securityholder or an assignee, such as: TEN COM (=tenants in common), TEN ENT (=tenants by the entirety), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian),
U/G/M/A (=Uniform Gifts to Minors Act), and U/T/M/A (=Uniform Transfers to Minors Act). 
 The Company will furnish to any Securityholder
upon written request and without charge a copy of the Indenture and the Securities Resolution, which contains the text of this Security in larger type. Requests may be made to: Corporate Secretary, Wisconsin Electric Power Company, 231 West Michigan
Street, P.O. Box 2046, Milwaukee, WI 53201.

 EXHIBIT 2 
 3.65% Debentures due December 15, 2042 
 Supplemental Terms 

In addition to the terms set forth in Exhibit 1 to Securities Resolution No. 12, the 3.65% Debentures shall have the following
terms: 
 Section 1. Definitions. Capitalized terms used and not defined herein shall have the meaning given such
terms in the Indenture. The following is an additional definition applicable to the 3.65% Debentures: 

“Depositary” means, with respect to the 3.65% Debentures, issued as one or more global Securities, The Depository Trust
Company, New York, New York, or any successor thereto registered under the Securities Exchange Act of 1934 or other applicable statute or regulation. 
 Section 2. Securities Issuable as Global Securities. 
 (a) The 3.65%
Debentures shall be issued in the form of one or more permanent global Securities and shall, except as otherwise provided in this Section 2, be registered only in the name of the Depositary or its nominee. Each global Security shall bear a
legend substantially to the following effect: 
 “Unless this certificate is presented by an authorized representative
of The Depository Trust Company, a New York corporation (“DTC”), to the Company or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the name of Cede & Co. or in such other
name as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein.” 
 (b) If at any time (i) the Depositary with respect to the 3.65% Debentures notifies the Company that it is unwilling or unable to continue as Depositary for such global Security or (ii) the
Depositary for the 3.65% Debentures shall no longer be eligible or in good standing under the Securities Exchange Act of 1934 or other applicable statute or regulation, the Company shall appoint a successor Depositary with respect to such global
Security. If a successor Depositary for such global Security is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Transfer Agent shall register the exchange of such global
Security for an equal principal amount of Registered Securities in the manner provided in Section 2.07 of the Indenture. 

 (c) The Transfer Agent shall register the transfer or exchange of a global Security for
Registered Securities pursuant to Section 2.07 of the Indenture if (i) a Default or Event of Default shall have occurred and be continuing with respect to the 3.65% Debentures, or (ii) the Company determines that the 3.65% Debentures
shall no longer be represented by global Securities. 
 (d) In any exchange provided for in the preceding paragraphs (b) or
(c), the Company will execute and the Registrar will authenticate and deliver Registered Securities. Registered Securities issued in exchange for a global Security shall be in such names and denominations as the Depositary for such global Security
shall instruct the Registrar. The Registrar shall deliver such Registered Securities to the persons in whose names such Securities are so registered. 
 (e) The 3.65% Debentures will trade in the Depositary’s Same-Day Funds Settlement System. All payments of principal and interest on global Securities will be made by the Company in immediately
available funds.

the Act subject to the terms and conditions therein specified. The Securities are to be issued under an indenture (the “Indenture”), dated as of April 25, 2012, between the Company, the Guarantors identified on Schedule

“Guarantees” and, together with the Notes, the “Securities”) as to the payment of principal and interest by the Guarantors. The Company has previously issued $250,000,000 in aggregate principal amount
of its 8.50% Notes due 2020 (the “Existing Notes”) under the Indenture. The Notes constitute “Additional Notes” (as such term is defined in the Indenture) under the Indenture. Except as otherwise disclosed in the

are no additional parties listed on Schedule I other than you, the term Representatives as used herein shall mean you as the Initial Purchasers, and the terms Representatives and Initial Purchasers shall mean either the singular or plural as
the context requires. The use of the neuter in this Agreement shall include the feminine and masculine wherever appropriate. Certain terms used herein are defined in Section 21 hereof. 

 The sale of the Securities to the Initial Purchasers will be made without registration of
the Securities under the Act in reliance upon exemptions from the registration requirements of the Act. 
 In connection with the
sale of the Securities, the Company has prepared a preliminary offering memorandum, dated December 5, 2012 (as amended or supplemented at the date thereof, including any and all exhibits thereto and any information incorporated by reference
therein, the “Preliminary Memorandum”), and will prepare a final offering memorandum, dated December 5, 2012 (as amended or supplemented at the Execution Time, including any and all exhibits thereto and any information
incorporated by reference therein, the “Final Memorandum”). The Preliminary Memorandum contains and the Final Memorandum will contain certain information concerning the Company and the Securities. The Company hereby confirms
that it has authorized the use of the Disclosure Package, the Preliminary Memorandum and the Final Memorandum, and any amendment or supplement thereto, in connection with the offer and sale of the Securities by the Initial Purchasers. Unless stated
to the contrary, any references herein to the terms “amend,” “amendment” or “supplement” with respect to the Disclosure Package, the Preliminary Memorandum and the Final Memorandum shall be deemed to refer to and
include any information filed under the Exchange Act subsequent to the Execution Time that is incorporated by reference therein.

(m) This Agreement has been duly authorized, executed and delivered by the Company and the Guarantors; the Indenture has been duly

the Company and the Guarantors, the statements in the Preliminary Memorandum and to be included in the Final Memorandum under the heading “Material U.S. Federal Income Tax Considerations” insofar as they purport to constitute summaries of

 (mm) The information underlying the estimates of reserves of the
Company included or to be included in the Disclosure Package and Final Memorandum, including, without limitation, production, costs of operation and development, current prices for production, agreements relating to current and future operations and
sales of production, was true and correct in all material respects on the dates such estimates were made and such information was supplied and was prepared in accordance with customary industry practices; other than normal production of the
reserves, intervening market commodity price fluctuations, fluctuations in demand for such products, adverse weather conditions, unavailability or increased costs of rigs, equipment, supplies, CO2 or personnel, the timing of third party operations, issues relating to
gathering, processing, refining or transportation and other than as described in the Disclosure Package and to be described in the Final Memorandum, the Company is not aware of any facts or circumstances that would result in a material adverse
change in the aggregate net reserves, or the present value of future net cash flows therefrom, as described in the Disclosure Package and the Final Memorandum; estimates of such reserves and present values as described in the Disclosure Package and
the Offering Memorandum comply in all material respects with the applicable requirements of Regulation S-X and Subpart 1200 of Regulation S-K under the Securities Act. 
 (nn) The Company and the Guarantors have valid, legal and defensible title to the interests in oil and gas properties underlying the estimates of the Company’s proved reserves described in the

not materially interfere with the use made or proposed to be made of such property by the Company or the Guarantors; any real property and buildings held under lease or sublease by the Company and the Guarantors are held by them under valid,
subsisting and enforceable leases, with such exceptions as are not material and do not interfere with the use made or proposed to be made of such property by the Company or the Guarantors; and the working interests derived from oil, gas and mineral
leases or mineral interests which constitute a portion of the real property held or leased by the Company and the Guarantors reflect in all material respects the right of the Company and the Guarantors to explore, develop or produce hydrocarbons
from such real property, and the care taken by the Company and the Guarantors with respect to acquiring or otherwise procuring such leases or mineral interests was generally consistent with standard industry practices in the areas in which the
Company and the Guarantors operate for acquiring or procuring leases and interests therein to explore, develop or produce hydrocarbons. 
 Any certificate signed by any officer of the Company or the Guarantors, as the case may be, and delivered to the Representatives or counsel for the Initial Purchasers in connection with the offering of

notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(i) assuming the accuracy of the representations and warranties and compliance with the agreements contained herein
(without regard to the representation found in Section 1(f)), no registration under the Act of the Securities, and no qualification of an indenture under the Trust Indenture Act, are required for the sale and delivery of the Securities by the
Company to the Initial Purchasers or the offer and sale by the Initial Purchasers of the Securities in the manner contemplated herein, in the Disclosure Package and in the Final Memorandum; 

  
 16 

 (ii) the Company is not, and after giving effect to the offering and sale of
the Securities and the application of the proceeds thereof as described in the Disclosure Package and the Final Memorandum, will not be, an “investment company” as defined in the Investment Company Act; 

(iii) except as described in the Disclosure Package and the Final Memorandum, to the knowledge of such counsel, there is
no pending or threatened action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator to which the Company or any of its subsidiaries is a party or of which its or their property is the subject,
except in each case for such proceedings that would not singly or in the aggregate reasonably be expected to have a Material Adverse Effect; and the statements in the Preliminary Memorandum and the Final Memorandum under the headings
“Material United States Federal Income Tax Considerations,” “Description of the Notes” and “Certain ERISA Considerations,” insofar as they purport to constitute summaries of (i) matters of United Stated federal tax
law and regulations or legal conclusions with respect thereto, (ii) the terms of statutes, rules or regulations, or (iii) certain provisions of the Indenture and the Securities, constitute accurate summaries of such matters in all material
respects; 
 (iv) each of the Company and the subsidiaries listed on Annex A attached hereto (individually,
a “Subsidiary” and collectively, the “Subsidiaries”) has been duly incorporated or formed and is validly existing as a corporation or limited liability company in good standing under the laws of the jurisdiction in which it is
chartered or organized, with full corporate or limited liability company power and authority to own or lease, as the case may be, and to operate its properties and conduct its business as described in the Disclosure Package and the Final Memorandum,

each Subsidiary have been duly authorized and validly issued and with respect to Subsidiaries that are corporations, are fully paid and nonassessable, and, except as otherwise set forth in the Disclosure Package and the Final Memorandum, all
outstanding shares of capital stock or membership interests of the Subsidiaries are owned by the Company either directly or through wholly owned subsidiaries free and clear of any security interest known to such counsel other than under the Credit
Facility. 

  
 17 

 (vii) none of the execution and delivery of the Registration Rights
Agreement or this Agreement, the issuance and sale of the Securities, nor the performance of the obligations hereunder, thereunder or under the Indenture by the Company and the Guarantors will conflict with, result in a breach or violation of, or
imposition of any lien, charge or encumbrance upon any property or asset of the Company or of any of its Subsidiaries pursuant to, (i) the charter or by-laws of the Company or the charter, by-laws or certificate of formation or operating
agreement of any of its Subsidiaries; (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, covenant or instrument to which the Company or any of its
Subsidiaries is a party or bound or to which its or their property is subject included on Schedule IV hereto; or (iii) any statute, law, rule, regulation, judgment, order or decree applicable to the Company or any of its Subsidiaries of any New
York, Delaware, Colorado or U.S. federal court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company, any of its Subsidiaries or any of their respective properties, except, in
the case of (ii) and (iii) above, for any such breach or violation that would not reasonably be expected to have a Material Adverse Effect and except with respect to the Credit Facility, on which we express no opinion; 

(viii) this Agreement has been duly authorized, executed and delivered by the Company; and the Registration Rights
Agreement has been duly authorized, executed and delivered by the Company; and the statements in the Preliminary Memorandum and Final Memorandum under the heading “Description of Notes,” insofar as such statements purport to summarize
certain provisions of the Registration Rights Agreement, are accurate summaries in all material respects; 
 (ix)
the Indenture has been duly authorized, executed and delivered by the Company and the Guarantors, and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a legal, valid and binding instrument enforceable
against the Company in accordance with its terms (subject, as to the enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent transfer or other laws affecting creditors’ rights generally from time to
time in effect and to general principles of equity); the Securities have been duly authorized by the Company and the Guarantors and, when executed and authenticated by the Trustee in accordance with the provisions of the Indenture and delivered to
and paid for by the Initial Purchasers under this Agreement, will constitute legal, valid, binding and enforceable obligations of the Company entitled to the benefits of the Indenture (subject, as to the enforcement of remedies, to applicable
bankruptcy, reorganization, insolvency, moratorium or other laws affecting creditors’ rights generally from time to time in effect and to general principles of equity);; and 

  
 18 

 (x) no consent, approval, authorization, filing with or order of any court
or governmental agency or body having jurisdiction over the Company or any of its Subsidiaries is required to be made by the Company or any of its Subsidiaries under the federal laws of the United States of America, the laws of the State of
New York, the laws of the State of Colorado, the Delaware General Corporation Law, and the Delaware Limited Liability Company Act that in our experience normally would be applicable to general business entities for the transactions contemplated
herein, in the Indenture or in the Registration Rights Agreement, except for (i) the filing of one or more registration statements or amendments to existing registration statements by the Company with the U.S. Securities and Exchange Commission
pursuant to the Act as required by the Registration Rights Agreement, (ii) the filing by the Company of a Form 8-K to report the transactions contemplated by the Agreement, (iii) such consents, approvals, authorizations, orders, filings,
registrations or qualifications as may be required under blue sky or securities laws of any jurisdiction in which the Securities are offered or sold in connection with the purchase and distribution of the Securities by the Initial Purchasers; and
(iv) such other approvals as have been obtained. 
 In addition, Davis, Graham & Stubbs LLP shall state that,
although such counsel has not independently verified, and is not passing on and does not pass on or assume responsibility for, the accuracy, completeness or fairness of the statements contained in the Disclosure Package or the Final Memorandum, no
facts have come to the attention of such counsel that would cause it to believe that (i) the Disclosure Package, as amended or supplemented at the Execution Time, contained any untrue statement of a material fact or omitted to state any
material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (in each case, other than the financial statements and other financial or reserve information contained
therein, as to which such counsel need express no opinion), and (ii) the Final Memorandum, as of its date or on the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact
necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (in each case, other than the financial statements (including the notes thereto) and other financial and reserve information
contained therein, as to which such counsel need express no opinion). 
 In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the jurisdiction of incorporation of the Company, the State of New York or the federal laws of the United States, to the extent they deem proper and specified in such opinion, upon the
opinion of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Initial Purchasers and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of
the Company and public officials. References to the Disclosure Package, the Preliminary Memorandum and the Final Memorandum in this Section 6(a) include any amendment or supplement thereto at the Closing Date. 

(b) The Company shall have requested and caused Thompson & Knight LLP, counsel for the Company, to furnish the Representatives
its opinion, dated the Closing Date and addressed to the Representatives, to the effect that none of the execution and delivery of the Registration Rights Agreement or this Agreement, the issuance and sale of the Securities, nor the performance of
the obligations hereunder, thereunder or under the Indenture by the Company and the Guarantors will conflict with, result in a breach or violation of, or imposition of any lien, charge or encumbrance upon any property or asset of the Company or any
of its subsidiaries pursuant to the Credit Facility. 

  
 19 

 (c) The Representatives shall have received from Latham & Watkins LLP, counsel for
the Initial Purchasers, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Indenture, the Registration Rights Agreement, the Disclosure Package, the
Final Memorandum (as amended or supplemented at the Closing Date) and other related matters as the Representatives may reasonably require, and the Company and the Guarantors shall have furnished to such counsel such documents as they request for the
purpose of enabling them to pass upon such matters. 
 (d) The Company and each Guarantor shall have furnished to the
Representatives a certificate, signed by the Company’s and each Guarantors’ (x) the Chairman of the Board or the President and (y) the principal financial or accounting officer, dated the Closing Date, to the effect that the
signers of such certificate have carefully examined the Disclosure Package and the Final Memorandum and any supplements or amendments thereto, and this Agreement and that: 

(i) the representations and warranties of the Company and the Guarantors in this Agreement are true and correct in all
materials respects (except to the extent already qualified by materiality, in which case such representations are true and correct in all respects) on and as of the Closing Date with the same effect as if made on the Closing Date, and each of the
Company and the Guarantors have complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; and 

(ii) since the date of the most recent financial statements included or incorporated by reference in the Disclosure
Package and the Final Memorandum (exclusive of any amendment or supplement thereto), there has been no material adverse change in the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its
subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement
thereto). 
 (e) At the Execution Time and at the Closing Date, the Company shall have requested and caused KPMG LLP to furnish
to the Representatives letters, dated respectively as of the Execution Time and as of the Closing Date, confirming that they are a registered public accounting firm and independent accountants within the meaning of the Exchange Act and substantially
in the form of Exhibit A hereto. 
 (f) Subsequent to the Execution Time or, if earlier, the dates as of which information is
given in the Disclosure Package (exclusive of any amendment or supplement thereto) and the Final Memorandum (exclusive of any amendment or supplement thereto), there shall not have been (i) any change or decrease specified in the letter or
letters referred to in paragraph (e) of this Section 6; or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), prospects, earnings, business or properties of the
Company and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or
supplement thereto), the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering
or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto). 

  
 20 

 (g) At the Execution Time and at the Closing Date, the Company shall have requested and
caused Deloitte & Touche LLP to furnish to the Representatives letters, dated respectively as of the Execution Time and as of the Closing Date, confirming that they were a registered public accounting firm and independent accountants within
the meaning of the Exchange Act and substantially in the form of Exhibit B hereto. 
 (h) At the Execution Time and the Closing

the Representatives and confirming that they are independent petroleum engineers and covering certain matters relating to information about the reserves of the Company presented in the Disclosure Package and Final Memorandum. 

(i) At the Execution Time and the Closing Date, the Representatives shall have received certificates, dated as of the Execution Time and
the Closing Date, of the chief financial officer of the Company, in customary form and substance reasonably satisfactory to the Representatives concerning certain of the financial information set forth in the Disclosure Package and Final Memorandum.

 (j) The Securities shall be eligible for clearance and settlement through The Depository Trust Company, Euroclear System and
Clearstream Banking S.A. 
 (k) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of
the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined under Section 3(a)(62) of the Exchange Act) or any notice given of any intended or potential decrease in any such rating or
of a possible change in any such rating that does not indicate the direction of the possible change. 
 (l) Prior to the Closing
Date, the Company and the Guarantors shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request. 

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any
of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Initial Purchasers, this Agreement and all obligations of the
Initial Purchasers hereunder may be cancelled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing. 

  
 21 

 The documents required to be delivered by this Section 6 will be delivered at the
office of counsel for the Initial Purchasers, at Latham & Watkins LLP, 811 Main Street, Suite 3700, Houston, Texas 77002, on the Closing Date. 
 7. Reimbursement of Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6
hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by
reason of a default by any of the Initial Purchasers, the Company will reimburse the Initial Purchasers severally through Citigroup on demand for all expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by
them in connection with the proposed purchase and sale of the Securities. 
 8. Indemnification and Contribution.
(a) The Company and each of the Guarantors, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees, Affiliates and agents of each Initial Purchaser and each person who controls
any Initial Purchaser within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other
U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities or actions in respect thereof arise out of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the Preliminary Memorandum, the Final Memorandum, any Issuer Written Information or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities, or in any
amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under
which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability
or action; provided, however, that the Company and the Guarantors will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made in the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by
or on behalf of any Initial Purchaser through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company or the Guarantors may otherwise have. 

(b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Company, each of the
Guarantors, each of their respective directors, each of their respective officers, and each person who controls the Company or the Guarantors within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity to
each Initial Purchaser, but only with reference to written information relating to such Initial Purchaser furnished to the Company by or on behalf of such Initial Purchaser through the Representatives specifically for inclusion in the Preliminary
Memorandum or the Final Memorandum (or in any amendment or supplement thereto). This indemnity agreement will be in addition to any liability that any Initial Purchaser may otherwise have. The Company acknowledges that (i) the statements set
forth in the last paragraph of the cover page regarding delivery of the Securities and (ii), under the heading “Plan of Distribution,” (A) the concession and reallowance figures in the Preliminary Memorandum and Final Memorandum, and
(B) the 9th and 10th paragraphs, in the Preliminary Memorandum and the Final Memorandum
constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum or in any amendment or supplement thereto. 

  
 22 

 (c) Promptly after receipt by an indemnified party under this Section 8 of notice of
the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure
so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or
(b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified
party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to
represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if
(i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the
indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the
indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the
indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or
consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. 

  
 23 

 (d) In the event that the indemnity provided in paragraph (a) or (b) of this
Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other, severally agree to contribute to the aggregate losses,
claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “Losses”) to which the Company,
the Guarantors and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and by the Initial Purchasers on the other
from the offering of the Securities; provided, however, that in no case shall any Initial Purchaser be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial
Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other, severally shall contribute in such
proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other, in connection with the statements or omissions that
resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company or the Guarantors shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it,
and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact relates to information provided by the Company or the Guarantors, on the one hand, or the Initial Purchasers, on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro
rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Initial Purchaser within the
meaning of either the Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company or the
Guarantors within the meaning of either the Act or the Exchange Act and each officer and director of the Company or the Guarantors shall have the same rights to contribution as the Company and the Guarantors, subject in each case to the applicable
terms and conditions of this paragraph (d). 
 9. Default by an Initial Purchaser. If any one or more Initial
Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this
Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate
principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in
the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I
hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement
will terminate without liability to any nondefaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five
Business Days, as the Representatives shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial
Purchaser of its liability, if any, to the Company or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder. 

  
 24 

 10. Termination. This Agreement shall be subject to termination in the absolute
discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in securities generally on the New York Stock Exchange shall have been
suspended or limited or minimum prices shall have been established on such exchange; (ii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; or (iii) there shall have occurred any outbreak
or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or
inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto). 

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other
statements of the Company, the Guarantors or its or their officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the
Initial Purchasers or the Company or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or
cancellation of this Agreement. 
 12. Notices. All communications hereunder will be in writing and effective only on
receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to the Citigroup General Counsel (fax no.: (212) 816-7912) and confirmed to Citigroup at 388 Greenwich Street, New York, New York 10013, Attention: General
Counsel; or, if sent to the Company, will be mailed, delivered or telefaxed to 303-623-3628 and confirmed to it at 1675 Broadway, Suite 1950, Denver, Colorado 80202, Attention: Legal Department. 

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors
and the indemnified persons referred to in Section 8 hereof and their respective successors, and, except as expressly set forth in Section 5(j) hereof, no other person will have any right or obligation hereunder. 

14. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company
and the Initial Purchasers, or any of them, with respect to the subject matter hereof. 

  
 25 

 15. Applicable Law. This Agreement will be governed by and construed in accordance
with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. 
 16.
Waiver of Jury Trial. The Company and the Initial Purchasers hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement
or the transactions contemplated hereby. 
 17. No Fiduciary Duty. The Company and the Guarantors hereby acknowledge that
(a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Guarantors, on the one hand, and the Initial Purchasers and any Affiliate through which it may be
acting, on the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Company and the Guarantors and (c) the Company’s engagement of the Initial Purchasers in connection with the offering and
the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company and the Guarantors agree that they are solely responsible for making its own judgments in connection with the offering
(irrespective of whether any of the Initial Purchasers has advised or is currently advising the Company or the Guarantors on related or other matters). The Company and the Guarantors agree that they will not claim that the Initial Purchasers have
rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company or the Guarantors, in connection with such transaction or the process leading thereto. 

18. Waiver of Tax Confidentiality. Notwithstanding anything herein to the contrary, purchasers of the Securities (and each
employee, representative or other agent of a purchaser) may disclose to any and all persons, without limitation of any kind, the U.S. tax treatment and U.S. tax structure of any transaction contemplated herein and all materials of any kind
(including opinions or other tax analyses) that are provided to the purchasers of the Securities relating to such U.S. tax treatment and U.S. tax structure, other than any information for which nondisclosure is reasonably necessary in order to
comply with applicable securities laws. 
 19. Counterparts. This Agreement may be signed in one or more counterparts,
each of which shall constitute an original and all of which together shall constitute one and the same agreement.
