The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, any Series of Notes (or tranche of Notes), in an amount not less than 5% of the original aggregate principal amount of such Series of Notes (or tranche of Notes) to be prepaid in the case of a partial prepayment, at 100% of the principal amount so prepaid, plus the applicable Make-Whole Amount determined for the prepayment date with respect to such principal amount. Notwithstanding the foregoing, the Company may not prepay any Series of Notes (or tranche of Notes) pursuant to this Section 8.2 if a Default or Event of Default shall exist or would result from such optional prepayment unless all Notes at the time outstanding are prepaid on a pro rata basis. The Company will give each holder of Notes of the Series (or tranche) to be prepaid (with a copy to each other holder of Notes) written notice of each optional prepayment under this

Alabama Gas Corporation Master Note Purchase Agreement -20- 105447057.13 Section 8.2 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Notes of each Series (or tranche of Notes) to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated applicable Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each holder of Notes being prepaid a certificate of a Senior Financial Officer specifying the calculation of such applicable Make-Whole Amount as of the specified prepayment date. Section 8.3. Allocation of Partial Prepayments. In the case of each partial prepayment of the Notes pursuant to Section 8.2, the principal amount of the Notes of each Series (or tranche of Notes) to be prepaid shall be allocated among all of the Notes of such Series (or tranche) at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment. Section 8.4. Maturity; Surrender, Etc. In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and applicable Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note. Section 8.5. Purchase of Notes. The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes of any Series (or tranche) except (a) upon the payment or prepayment of the Notes of such Series (or tranche) in accordance with the terms of this Agreement (including any Supplement hereto) and the Notes of such Series (or tranche) or (b) pursuant to an offer to purchase any outstanding Notes of any Series (or tranche) made by the Company or an Affiliate pro rata to the holders of the Notes of such Series (or tranche) at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder of the Notes of the Series (or tranche) being offered for purchase with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 10 Business Days. If the holders of more than 25% of the outstanding principal amount of the Notes of the Series (or tranche) offered for purchase accept such offer, the Company shall promptly notify the remaining holders of such Series (or tranche) of such fact and the expiration date for the acceptance by such holders of such offer shall be extended by the number of days necessary to give each such remaining holder at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may

Alabama Gas Corporation Master Note Purchase Agreement -21- 105447057.13 be issued in substitution or exchange for any such Notes. Notwithstanding the foregoing, neither the Company nor any Affiliate may offer to purchase or purchase any Series (or tranche) of Notes if a Default or Event of Default shall exist or would result therefrom unless such Person shall offer to purchase all outstanding Notes on a pro rata basis upon the same terms and conditions. Section 8.6. Make-Whole Amount for the Series 2015 Notes. “Make-Whole Amount” means, with respect to any Series 2015 Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Series 2015 Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings: “Called Principal” means, with respect to any Series 2015 Note, the principal of such Series 2015 Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. “Discounted Value” means, with respect to the Called Principal of any Series 2015 Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Series 2015 Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. “Reinvestment Yield” means, with respect to the Called Principal of any Series 2015 Note, 0.5% over the yield to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note. If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Series 2015 Note, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to

Alabama Gas Corporation Master Note Purchase Agreement -22- 105447057.13 such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Series 2015 Note. “Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. “Remaining Scheduled Payments” means, with respect to the Called Principal of any Series 2015 Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the Series 2015 Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.4 or Section 12.1. “Settlement Date” means, with respect to the Called Principal of any Series 2015 Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. Section 8.7. Change in Control. (a) Notice of Change in Control. The Company will, within 5 Business Days after any Responsible Officer has knowledge of the occurrence of any Change in Control, give written notice of such Change in Control to each holder of Notes. If a Change in Control has occurred, such notice shall contain and constitute an offer by the Company to prepay the Notes as described in subparagraph (c) of this Section 8.7 and shall be accompanied by the certificate described in subparagraph (e) of this Section 8.7. (b) Offer to Prepay Notes. The offer to prepay Notes contemplated by the foregoing paragraph (a) of this Section 8.7 shall be an offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, of the Notes held by each holder (in this case only, “holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”). Such Proposed Prepayment Date shall be not less than 10 days and not more than 30 days after the date of such offer (or, if the Proposed Prepayment Date shall not be

Alabama Gas Corporation Master Note Purchase Agreement -23- 105447057.13 specified in such offer, the Proposed Prepayment Date shall be the 20th day after the date of such offer). (c) Acceptance; Rejection. A holder of Notes may accept or reject the offer to prepay made pursuant to this Section 8.7 by causing a notice of such acceptance or rejection to be delivered to the Company at least 5 Business Days prior to the Proposed Prepayment Date. A failure by a holder of Notes to so respond to an offer to prepay made pursuant to this Section 8.7 shall be deemed to constitute a rejection of such offer by such holder. (d) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal amount of such Notes, together with interest on such Notes accrued to the date of prepayment. The prepayment shall be made on the Proposed Prepayment Date. (e) Officer’s Certificate. Each offer to prepay the Notes pursuant to this Section 8.7 shall be accompanied by a certificate, executed by a Senior Financial Officer of the Company and dated the date of such offer, specifying: (i) the Proposed Prepayment Date; (ii) that such offer is made pursuant and subject to this Section 8.7; (iii) the principal amount of each Note offered to be prepaid; (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions of this Section 8.7 have been fulfilled or, as applicable, will be fulfilled on or prior to the date prepayment becomes due under this Section 8.7; and (vi) in reasonable detail, the nature and date or proposed date of the Change in Control. SECTION 9. AFFIRMATIVE COVENANTS. The Company covenants that from and after the Execution Date and so long as any of the Notes are outstanding: Section 9.1. Compliance with Law.

Section 9.2. Insurance. The Company will and will cause each of its Subsidiaries to maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves

Section 9.4. Payment of Taxes. The Company will and will cause each of its Subsidiaries to file all income tax or similar tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies payable by any of them, to the extent the same have become due and payable and before they have become delinquent, provided that neither the Company nor any Subsidiary need pay any such tax, assessment, charge or levy if (i) the amount, applicability or validity thereof is contested by the Company or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Company or a Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary or (ii) the nonpayment of all such taxes, assessments, charges and levies in the aggregate would not reasonably be expected to have a Material Adverse Effect. Section 9.5. Corporate Existence, Etc. Subject to Section 10.2, the Company will at all times preserve and keep in full force and effect its corporate existence. Subject to Sections 10.2 and 10.6 the Company will at all times preserve and keep in full force and effect the corporate existence of each of its Subsidiaries (unless merged into the Company or a Wholly-Owned Subsidiary) and all rights and franchises of the Company and its Subsidiaries unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Prior to any sale or other disposition of any Note held by a Purchaser or an Additional Purchaser or such Person’s nominee, such Purchaser or Additional Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes of the same tranche pursuant to Section 13.2. The Company will afford the benefits of this Section 14.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by a Purchaser or an Additional Purchaser under this Agreement (including any Supplement hereto) and that has made the same agreement relating to such Note as the Purchasers or Additional Purchasers, as the case may be, have made in this Section 14.2.

Section 17.3. Binding Effect, Etc. Any amendment or waiver consented to as provided in this Section 17 applies equally to all Purchasers, Additional Purchasers or holders of Notes and is binding upon them and upon each future holder of any Note and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the Purchaser, the Additional Purchaser or holder of any Note nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any Purchaser, Additional Purchaser or holder of such Note.

Alabama Gas Corporation Master Note Purchase Agreement -39- 105447057.13 Confidential Information to be bound by the provisions of this Section 20), (v) any Person from which it offers to purchase any Security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (vi) any Governmental Authority having jurisdiction over such Purchaser, Additional Purchaser or holder of Notes, (vii) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s, Additional Purchaser’s or holder’s investment portfolio, or (viii) any other Person to which such delivery or disclosure is necessary (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, Additional Purchaser or holder of Notes, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Purchaser, Additional Purchaser or holder of Notes is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser, Additional Purchaser or holder of Notes may reasonably determine such delivery and disclosure to be necessary in the enforcement or for the protection of the rights and remedies under such Purchaser’s, Additional Purchaser’s or holder’s Notes and this Agreement. Notwithstanding anything to the contrary, prior to any Purchaser, Additional Purchaser or holder of Notes making any permitted disclosure described in clause (x) above (or clause (vi) above but only to the extent such request or demand is specifically targeted at the Company or otherwise arising out of the transactions contemplated hereby), to the extent not prohibited by law or regulation such Purchaser, Additional Purchaser or holder of Notes shall use its reasonable efforts to promptly notify the Company in writing and shall use its reasonable efforts to assist the Company (at the Company’s sole expense) to protest and/or challenge any such required or requested disclosures. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement, any Supplement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 20. In the event that as a condition to receiving access to information relating to the Company or its Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Note is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual workspace or otherwise) which is different from this Section 20, this Section 20 shall not be amended thereby and, as between such Purchaser or such holder and the Company, this Section 20 shall supersede any such other confidentiality undertaking.

Each Purchaser and each Additional Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that it has agreed to purchase hereunder or under any Supplement, by written notice to the Company, which notice shall be signed by both such Purchaser or such Additional Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and such Supplement, as applicable, and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth

Alabama Gas Corporation Master Note Purchase Agreement -40- 105447057.13 in Section 6. Upon receipt of such notice, any reference to such Purchaser or such Additional Purchaser in this Agreement (other than in this Section 21) and such Supplement, as applicable, shall be deemed to refer to such Affiliate in lieu of such original Purchaser or such original Additional Purchaser. In the event that such Affiliate is so substituted as a Purchaser or an Additional Purchaser hereunder or under any Supplement and such Affiliate thereafter transfers to such original Purchaser or such original Additional Purchaser all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, any reference to such Affiliate as a “Purchaser” or an “Additional Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Affiliate, but shall refer to such original Purchaser or such original Additional Purchaser, and such original Purchaser or original Additional Purchaser shall again have all the rights of an original holder of Notes under this Agreement and such Supplement, as applicable. SECTION 22. MISCELLANEOUS. Section 22.1. Successors and Assigns. All covenants and other agreements contained in this Agreement (including all covenants and other agreements contained in any Supplement) by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. Section 22.2. Payments Due on Non-Business Days. Anything in this Agreement, any Supplement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.4 that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day. Section 22.3. Accounting Terms. All accounting terms used herein or used in any Supplement which are not expressly defined in this Agreement or such Supplement, as applicable, have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein or in any Supplement, (i) all computations made pursuant to this Agreement or such Supplement, as applicable, shall be made in accordance with GAAP, and (ii) all financial statements shall be prepared in accordance with GAAP. Notwithstanding the foregoing, if the Company notifies the holders of Notes that, in the Company’s reasonable opinion, or if the Required Holders notify the Company that, in the Required Holders’ reasonable opinion, as a result of changes in GAAP from time to time (“Subsequent Changes”), any of the covenants contained in Sections 10.5 or 10.6 or any of the defined terms used therein, no longer apply as intended such that such covenants are materially more or less restrictive to the Company than are such covenants immediately prior to giving effect to such Subsequent Changes, the Company and the holders of Notes shall negotiate in good faith to reset or amend such covenants or defined terms so as to negate such Subsequent Changes, or to establish alternative covenants

Alabama Gas Corporation Master Note Purchase Agreement -41- 105447057.13 or defined terms. Until the Company and the Required Holders so agree to reset, amend or establish alternative covenants or defined terms, the covenants contained in Sections 10.5 and 10.6, together with the relevant defined terms, shall continue to apply and compliance therewith shall be determined assuming that the Subsequent Changes shall not have occurred (“Static GAAP”). During any period that compliance with any covenants shall be determined pursuant to Static GAAP, the Company shall include relevant reconciliations in reasonable detail between GAAP and Static GAAP with respect to the applicable covenant compliance calculations contained in each certificate of a Senior Financial Officer delivered pursuant to Section 7.2 during such period. In determining compliance with the requirements of the covenants contained in this Agreement, any election by the Company to measure any portion of Indebtedness at fair value (as permitted by International Accounting Standard 39 or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been made. Section 22.4. Severability. Any provision of this Agreement or any Supplement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or thereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction. Section 22.5. Construction, Etc. Each covenant contained herein or in any Supplement shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, or therein so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein or in any Supplement refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a part hereof. Section 22.6. Counterparts. This Agreement and any Supplement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto. Section 22.7. Governing Law. This Agreement and each Supplement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State. Section 22.8. Jurisdiction and Process; Waiver of Jury Trial. (a) The Company and each Purchaser, Additional Purchaser and holder of Notes hereby irrevocably submits to the exclusive jurisdiction of any federal court sitting in the Borough of Manhattan, The City of New York,

Alabama Gas Corporation Master Note Purchase Agreement -42- 105447057.13 over any suit, action or proceeding arising out of or relating to this Agreement, any Supplement or the Notes; provided that if no such federal court has jurisdiction to accept such suit, action or proceeding, then the Company and each Purchaser, Additional Purchaser and holder of Notes irrevocably and unconditionally submits to the exclusive jurisdiction of any state court sitting in the Borough of Manhattan, The City of New York. To the fullest extent permitted by applicable law, the Company and each Purchaser, Additional Purchaser and holder of Notes irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. (b) The Company consents to process being served by or on behalf of any Purchaser, Additional Purchaser or holder of Notes in any suit, action or proceeding of the nature referred to in Section 22.8(a) by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, return receipt requested, to it at its address specified in Section 18 or at such other address of which such party shall then have been notified pursuant to said Section. The Company agrees that such service upon receipt (i) shall be deemed in every respect effective service of process upon it in any such suit, action or proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it. Notices hereunder shall be conclusively presumed received as evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service. (c) Nothing in this Section 22.8 shall affect the right of any Purchaser, Additional Purchaser or holder of a Note to serve process in any manner permitted by law, or limit any right that the Purchasers, Additional Purchasers or holders of any of the Notes may have to bring proceedings against the Company in the courts of any appropriate jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction. (d) THE COMPANY AND EACH PURCHASER, ADDITIONAL PURCHASER AND EACH HOLDER OF NOTES HEREBY WAIVES TRIAL BY JURY IN ANY ACTION BROUGHT ON OR WITH RESPECT TO THIS AGREEMENT, ANY SUPPLEMENT, THE NOTES OR ANY OTHER DOCUMENT EXECUTED IN CONNECTION HEREWITH OR THEREWITH. * * * * *

The Company is not, and after giving effect to the offering and sale of the Series 2015 Notes, and the application of the proceeds thereof as described in the Note Purchase Agreement will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

105447057.13 SUBSIDIARY GUARANTY AGREEMENT THIS SUBSIDIARY GUARANTY AGREEMENT, dated as of [_______________, 20__] (this “Subsidiary Guaranty Agreement”), is made by [each of] the undersigned ([each a][the] “Guarantor” and, together with [each of the other signatories hereto and] any other entities from time to time parties hereto pursuant to Section 15.1 hereof, the “Guarantors”) in favor of the Purchasers (as defined below) and the other holders from time to time of the Notes (as defined below). The Purchasers and such other holders are herein collectively called the “holders” and individually a “holder.” PRELIMINARY STATEMENTS: I. Alabama Gas Corporation, an Alabama corporation (the “Company”), has entered into a Master Note Purchase Agreement dated as of June 5, 2015 (as amended, modified, supplemented or restated from time to time, the “Note Agreement”) with the Persons listed on the signature pages thereto (the “Purchasers”). Capitalized terms used herein have the meanings specified in the Note Agreement unless otherwise defined herein. II. The Company has authorized the issuance, pursuant to the Note Agreement, of its (a) 3.21% Series 2015 Senior Notes, Tranche A, due September 15, 2025 in the aggregate principal amount of $35,000,000 and (b) 4.31% Series 2015 Senior Notes, Tranche B, due December 1, 2045 in the aggregate principal amount of $80,000,000. Pursuant to the Note Agreement, the Company has issued and sold (a) $35,000,000 aggregate principal amount of its 3.21% Series 2015 Senior Notes, Tranche A, due September 15, 2025 and (b) $80,000,000 aggregate principal amount of its 4.31% Series 2015 Senior Notes, Tranche B, due December 1, 2045 (collectively, the “Initial Notes”). The Company is authorized to issue Additional Notes (as such term is defined in the Note Agreement) of one or more separate series from time to time pursuant to Section 1.2 of the Note Agreement. The Initial Notes, the Additional Notes and any other Notes that may from time to time be issued pursuant to the Note Agreement (including any notes issued in substitution for any of the Notes) are herein collectively called the “Notes” and individually a “Note”. III. Pursuant to the Note Agreement, the Company is required to cause [each][the] Guarantor to deliver this Subsidiary Guaranty Agreement to the holders. IV. [Each][The] Guarantor will receive direct and indirect benefits from the financing arrangements contemplated by the Note Agreement. The [Board of Directors] of [each][the] Guarantor has determined that the incurrence of such obligations is in the best interests of such Guarantor. NOW THEREFORE, in compliance with the Note Agreement, and in consideration of, the execution and delivery of the Note Agreement and the purchase of the Notes by each of the Purchasers, [each][the] Guarantor hereby covenants and agrees with, and represents and warrants to each of the holders as follows:

9.8-2 105447057.13 SECTION 1. GUARANTY. [Each][The] Guarantor hereby irrevocably, unconditionally [and jointly and severally with the other Guarantors] guarantees to each holder, the due and punctual payment in full of (a) the principal of, Make-Whole Amount, if any, and interest on (including, without limitation, interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, whether or not a claim for post-filing or post- petition interest is allowed in such proceeding), and any other amounts due under, the Notes when and as the same shall become due and payable (whether at stated maturity or by required or optional prepayment or by acceleration or otherwise) and (b) any other sums which may become due under the terms and provisions of the Notes, the Note Agreement or any other instrument referred to therein (all such obligations described in clauses (a) and (b) above are herein called the “Guaranteed Obligations”). The guaranty in the preceding sentence is an absolute, present and continuing guaranty of payment and not of collectability and is in no way conditional or contingent upon any attempt to collect from the Company or any other guarantor of the Notes (including, without limitation, any other Guarantor hereunder) or upon any other action, occurrence or circumstance whatsoever. In the event that the Company shall fail so to pay any of such Guaranteed Obligations, [each][the] Guarantor agrees to pay the same when due to the holders entitled thereto, without demand, presentment, protest or notice of any kind, in lawful money of the United States of America, pursuant to the requirements for payment specified in the Notes and the Note Agreement. Each default in payment of any of the Guaranteed Obligations shall give rise to a separate cause of action hereunder and separate suits may be brought hereunder as each cause of action arises. [Each][The] Guarantor agrees that the Notes issued in connection with the Note Agreement may (but need not) make reference to this Subsidiary Guaranty Agreement. [Each][The] Guarantor agrees to pay and to indemnify and save each holder harmless from and against any damage, loss, cost or expense (including attorneys’ fees) which such holder may incur or be subject to as a consequence, direct or indirect, of (x) any breach by such Guarantor[, by any other Guarantor] or by the Company of any warranty, covenant, term or condition in, or the occurrence of any default under, this Subsidiary Guaranty Agreement, the Notes or the Note Agreement or any other instrument referred to therein, together with all expenses resulting from the compromise or defense of any claims or liabilities arising as a result of any such breach or default, (y) any legal action commenced to challenge the validity or enforceability of this Subsidiary Guaranty Agreement, the Notes, the Note Agreement or any other instrument referred to therein and (z) enforcing or defending (or determining whether or how to enforce or defend) the provisions of this Subsidiary Guaranty Agreement. [Each][The] Guarantor hereby acknowledges and agrees that such Guarantor’s liability hereunder is joint and several with [the other Guarantors and] any other Person(s) who may guarantee the obligations and Indebtedness under and in respect of the Notes and the Note Agreement. Notwithstanding the foregoing provisions or any other provision of this Subsidiary Guaranty Agreement, the holders (on behalf of themselves and their successors and assigns) and [each][the] Guarantor hereby agree that if at any time the Guaranteed Obligations exceed the

9.8-3 105447057.13 Maximum Guaranteed Amount determined as of such time with regard to such Guarantor, then this Subsidiary Guaranty Agreement shall be automatically amended to reduce the Guaranteed Obligations to the Maximum Guaranteed Amount. Such amendment shall not require the written consent of [any][the] Guarantor or any holder and shall be deemed to have been automatically consented to by [each][the] Guarantor and each holder. [Each][The] Guarantor agrees that the Guaranteed Obligations may at any time exceed the Maximum Guaranteed Amount without affecting or impairing the obligation of such Guarantor. “Maximum Guaranteed Amount” means as of the date of determination with respect to a Guarantor, the lesser of (a) the amount of the Guaranteed Obligations outstanding on such date and (b) the maximum amount that would not render such Guarantor’s liability under this Subsidiary Guaranty Agreement subject to avoidance under Section 548 of the United States Bankruptcy Code (or any successor provision) or any comparable provision of applicable state law. SECTION 2. OBLIGATIONS ABSOLUTE. Subject to Section 9.8(c) of the Note Agreement, the obligations of [each][the] Guarantor hereunder shall be primary, absolute, irrevocable and unconditional, irrespective of the validity or enforceability of the Notes, the Note Agreement or any other instrument referred to therein, shall not be subject to any counterclaim, setoff, deduction or defense based upon any claim such Guarantor may have against the Company or any holder or otherwise, and shall remain in full force and effect without regard to, and shall not be released, discharged or in any way affected by, any circumstance or condition whatsoever (whether or not such Guarantor shall have any knowledge or notice thereof), including, without limitation: (a) any amendment to, modification of, supplement to or restatement of the Notes, the Note Agreement or any other instrument referred to therein (it being agreed that the obligations of [each][the] Guarantor hereunder shall apply to the Notes, the Note Agreement or any such other instrument as so amended, modified, supplemented or restated) or any assignment or transfer of any thereof or of any interest therein, or any furnishing, acceptance or release of any security for the Notes or the addition, substitution or release of any other Guarantor or any other entity or other Person primarily or secondarily liable in respect of the Guaranteed Obligations; (b) any waiver, consent, extension, indulgence or other action or inaction under or in respect of the Notes, the Note Agreement or any other instrument referred to therein; (c) any bankruptcy, insolvency, arrangement, reorganization, readjustment, composition, liquidation or similar proceeding with respect to the Company or its property; (d) any merger, amalgamation or consolidation of [any][the] Guarantor or of the Company into or with any other Person or any sale, lease or transfer of any or all of the assets of [any][the] Guarantor or of the Company to any Person; (e) any failure on the part of the Company for any reason to comply with or perform any of the terms of any other agreement with [any][the] Guarantor; (f) any failure on the part of any holder to obtain, maintain, register or otherwise perfect any security; or (g) any other event or circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor (whether or not similar to the foregoing), and in any event however material or prejudicial it may be to [any][the] Guarantor or to any subrogation, contribution or reimbursement rights [any][the] Guarantor may otherwise have. [Each][The] Guarantor covenants that its obligations hereunder will not be discharged except by indefeasible payment in full in cash of all of the Guaranteed Obligations and all other obligations hereunder or otherwise in accordance with Section 9.8(c) of the Note Agreement.

9.8-4 105447057.13 SECTION 3. WAIVER. [Each][The] Guarantor unconditionally waives to the fullest extent permitted by law, (a) notice of acceptance hereof, of any action taken or omitted in reliance hereon and of any default by the Company in the payment of any amounts due under the Notes, the Note Agreement or any other instrument referred to therein, and of any of the matters referred to in Section 2 hereof, (b) all notices which may be required by statute, rule of law or otherwise to preserve any of the rights of any holder against such Guarantor, including, without limitation, presentment to or demand for payment from the Company or [any][the] Guarantor with respect to any Note, notice to the Company or to [any][the] Guarantor of default or protest for nonpayment or dishonor and the filing of claims with a court in the event of the bankruptcy of the Company, (c) any right to require any holder to enforce, assert or exercise any right, power or remedy including, without limitation, any right, power or remedy conferred in the Note Agreement or the Notes, (d) any requirement for diligence on the part of any holder and (e) any other act or omission or thing or delay in doing any other act or thing which might in any manner or to any extent vary the risk of such Guarantor or otherwise operate as a discharge of such Guarantor or in any manner lessen the obligations of such Guarantor hereunder. SECTION 4. OBLIGATIONS UNIMPAIRED. [Each][The] Guarantor authorizes the holders, without notice or demand to such Guarantor [or any other Guarantor] and without affecting its obligations hereunder, from time to time: (a) to renew, compromise, extend, accelerate or otherwise change the time for payment of, all or any part of the Notes, the Note Agreement or any other instrument referred to therein; (b) to change any of the representations, covenants, events of default or any other terms or conditions of or pertaining to the Notes, the Note Agreement or any other instrument referred to therein, including, without limitation, decreases or increases in amounts of principal, rates of interest, the Make-Whole Amount or any other obligation; (c) to take and hold security for the payment of the Notes, the Note Agreement or any other instrument referred to therein, for the performance of this Subsidiary Guaranty Agreement or otherwise for the Indebtedness guaranteed hereby and to exchange, enforce, waive, subordinate and release any such security; (d) to apply any such security and to direct the order or manner of sale thereof as the holders in their sole discretion may determine; (e) to obtain additional or substitute endorsers or guarantors or release any other Guarantor or any other Person or entity primarily or secondarily liable in respect of the Guaranteed Obligations; (f) to exercise or refrain from exercising any rights against the Company, [any][the] Guarantor or any other Person; and (g) to apply any sums, by whomsoever paid or however realized, to the payment of the Guaranteed Obligations and all other obligations owed hereunder. The holders shall have no obligation to proceed against any additional or substitute endorsers or guarantors or to pursue or exhaust any security provided by the Company, such Guarantor [or any other Guarantor] or any other Person or to pursue any other remedy available to the holders. If an event permitting the acceleration of the maturity of the principal amount of any Notes shall exist and such acceleration shall at such time be prevented or the right of any holder to receive any payment on account of the Guaranteed Obligations shall at such time be delayed or otherwise affected by reason of the pendency against the Company, [any][the] Guarantor or

9.8-5 105447057.13 any other guarantors of a case or proceeding under a bankruptcy or insolvency law, such Guarantor agrees that, for purposes of this Subsidiary Guaranty Agreement and its obligations hereunder, the maturity of such principal amount shall be deemed to have been accelerated with the same effect as if the holder thereof had accelerated the same in accordance with the terms of the Note Agreement, and such Guarantor shall forthwith pay such accelerated Guaranteed Obligations. SECTION 5. SUBROGATION AND SUBORDINATION. (a) [Each][The] Guarantor will not exercise any rights which it may have acquired by way of subrogation under this Subsidiary Guaranty Agreement, by any payment made hereunder or otherwise, or accept any payment on account of such subrogation rights, or any rights of reimbursement, contribution or indemnity or any rights or recourse to any security for the Notes or this Subsidiary Guaranty Agreement unless and until all of the Guaranteed Obligations shall have been indefeasibly paid in full in cash. (b) [Each][The] Guarantor hereby subordinates the payment of all Indebtedness and other obligations of the Company or any other guarantor of the Guaranteed Obligations owing to such Guarantor, whether now existing or hereafter arising, including, without limitation, all rights and claims described in clause (a) of this Section 5, to the indefeasible payment in full in cash of all of the Guaranteed Obligations. If the Required Holders so request, any such Indebtedness or other obligations shall be enforced and performance received by such Guarantor as trustee for the holders and the proceeds thereof shall be paid over to the holders promptly, in the form received (together with any necessary endorsements) to be applied to the Guaranteed Obligations, whether matured or unmatured, as may be directed by the Required Holders, but without reducing or affecting in any manner the liability of [any][the] Guarantor under this Subsidiary Guaranty Agreement. (c) If any amount or other payment is made to or accepted by [any][the] Guarantor in violation of any of the preceding clauses (a) and (b) of this Section 5, such amount shall be deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the holders and shall be paid over to the holders promptly, in the form received (together with any necessary endorsements) to be applied to the Guaranteed Obligations, whether matured or unmatured, as may be directed by the Required Holders, but without reducing or affecting in any manner the liability of such Guarantor under this Subsidiary Guaranty Agreement. (d) [Each][The] Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Note Agreement and that its agreements set forth in this Subsidiary Guaranty Agreement (including this Section 5) are knowingly made in contemplation of such benefits. (e) [Each][The] Guarantor hereby agrees that, to the extent that a Guarantor shall have paid an amount hereunder to any holder that is greater than the net value of the benefits received, directly or indirectly, by such paying guarantor as a result of the issuance and sale of the Notes (such net value, its “Proportionate Share”), such paying guarantor shall, subject to Section 5(a) and 5(b), be entitled to contribution from any guarantor that has not paid its

9.8-6 105447057.13 Proportionate Share of the Guaranteed Obligations. Any amount payable as a contribution under this Section 5(e) shall be determined as of the date on which the related payment is made by such guarantor seeking contribution and [each][the] Guarantor acknowledges that the right to contribution hereunder shall constitute an asset of such Guarantor to which such contribution is owed. Notwithstanding the foregoing, the provisions of this Section 5(e) shall in no respect limit the obligations and liabilities of [any][the] Guarantor to the holders of the Notes hereunder or under the Notes, the Note Agreement or any other document, instrument or agreement executed in connection therewith, and [each][the] Guarantor shall remain jointly and severally liable for the full payment and performance of the Guaranteed Obligations. SECTION 6. REINSTATEMENT OF GUARANTY. This Subsidiary Guaranty Agreement shall continue to be effective, or be reinstated, as the case may be, if and to the extent at any time payment, in whole or in part, of any of the sums due to any holder on account of the Guaranteed Obligations is rescinded or must otherwise be restored or returned by a holder upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any other guarantors, or upon or as a result of the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to the Company or any other guarantors or any part of its or their property, or otherwise, all as though such payments had not been made. SECTION 7. RANK OF GUARANTY. [Each][The] Guarantor will ensure that its payment obligations under this Subsidiary Guaranty Agreement will at all times rank at least pari passu, without preference or priority, with all other unsecured and unsubordinated Indebtedness of such Guarantor now or hereafter existing.

SECTION 13. AMENDMENT AND WAIVER. Section 13.1. Requirements.

[Each][The] Guarantor will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with reasonably sufficient information, reasonably sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or

9.8-9 105447057.13 consent in respect of any of the provisions hereof. [Each][The] Guarantor will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 13.2 to each holder promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the Required Holders.

Section 13.3. Binding Effect. Any amendment or waiver consented to as provided in this Section 13 applies equally to all holders and is binding upon them and upon each future holder and upon [each][the] Guarantor without regard to whether any Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant or agreement not expressly amended or waived or impair any right consequent thereon. No course of dealing between [a][the] Guarantor and the holder nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any holder. As used herein, the term “this Subsidiary Guaranty Agreement” and references thereto shall mean this Subsidiary Guaranty Agreement as it may be amended, modified, supplemented or restated from time to time. Section 13.4. Notes Held by Company, Etc. Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Subsidiary Guaranty Agreement, or have directed the taking of any action provided herein to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by [any][the] Guarantor, the Company or any of their respective Affiliates shall be deemed not to be outstanding. SECTION 14. NOTICES. All notices and communications provided for hereunder shall be in writing and sent (a) by telecopy or electronic mail (to those recipients who have provided email addresses specifically for such purpose to the other parties hereto) if the sender on the same day sends a confirming copy of such notice by a recognized overnight delivery service (charges prepaid), or (b) by registered or certified mail with return receipt requested (postage prepaid), or (c) by a recognized overnight delivery service (with charges prepaid).

Any such Person shall thereafter be a “Guarantor” for all purposes under this Subsidiary Guaranty Agreement. Section 15.2. Severability. Any provision of this Subsidiary Guaranty Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law), not invalidate or render unenforceable such provision in any other jurisdiction. Section 15.3. Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such express contrary provision) be deemed to excuse compliance with any other covenant. Whether any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. The section and subsection headings in this Subsidiary Guaranty Agreement are for convenience of reference only and shall neither be deemed to be a part of this Subsidiary Guaranty Agreement nor modify, define, expand or limit any of the terms or provisions hereof. All references herein to numbered sections, unless otherwise indicated, are to sections of this Subsidiary Guaranty Agreement. Words and definitions in the singular shall be read and construed as though in the plural and vice versa, and words in the masculine, neuter or feminine gender shall be read and construed as though in either of the other genders where the context so requires. Section 15.4. Further Assurances. [Each][The] Guarantor agrees to execute and deliver all such instruments and take all such action as the Required Holders may from time to time reasonably request in order to effectuate fully the purposes of this Subsidiary Guaranty Agreement. Section 15.5. Governing Law. This Subsidiary Guaranty Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York, excluding choice-of-law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State.
