NEW MEXICO GAS INTERMEDIATE, INC., a Delaware corporation (the “Company”), agrees with each of the purchasers whose names appear at the end hereof (each, a “Purchaser” and, collectively, the “Purchasers”) as follows:

The Company will authorize the issue and sale of (a) $50,000,000 aggregate principal amount of its 2.71% Series A Senior Unsecured Notes due July 30, 2019 (the “Series A Notes”) and (b) $150,000,000 aggregate principal amount of its 3.64% Series B Senior Unsecured Notes due July 30, 2024 (the “Series B Notes” and, together with the Series A Notes, collectively, the “Notes”, such term to include any such notes issued in substitution therefor pursuant to Section 13). The Series A Notes and the Series B Notes shall be substantially in the respective forms set out in Exhibit 1(a) and Exhibit 1(b). Certain capitalized and other terms used in this Agreement are defined in Schedule B; and references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

Subject to the terms and conditions of this Agreement, the Company will issue and sell to each Purchaser and each Purchaser will purchase from the Company, at the Closing provided for in Section 3, Notes in the principal amount and in the series specified opposite such Purchaser’s name in Schedule A at the purchase price of 100% of the principal amount thereof. The Purchasers’ obligations hereunder are several and not joint obligations and no Purchaser shall have any liability to any Person for the performance or non-performance of any obligation by any other Purchaser hereunder.

The sale and purchase of the Notes to be purchased by each Purchaser shall occur at the offices of Bingham McCutchen LLP, One State Street, Hartford, Connecticut 06103-3178, at 9:00 a.m., local time, at a closing (the “Closing”) to occur on the date on which each of the conditions precedent set forth in Sections 3 and 4 hereof (including, without limitation, the consummation of the TECO Acquisition) shall have been satisfied (the day upon which the last of all of such conditions precedent shall have been satisfied being referred to as the “Closing Date”); provided that if all such conditions precedent shall not have been satisfied on or prior to October 15, 2014 this Agreement shall terminate and shall forthwith become void and be of no force and effect, without any liability on the part of any party (including, without limitation, with respect to the representations and warranties of the Company contained in this Agreement and any and all information contained in the Memorandum or any other Disclosure Documents or otherwise), and the Purchasers and the

Company and their respective affiliates shall each be permanently and irrevocably relieved of all obligations and liabilities under this Agreement. At least three (3) Business Days prior to the Closing Date, the Company shall provide written notice to the Purchasers specifying the proposed Closing Date (which shall be a Business Day). On the Closing Date, the Company will deliver to each Purchaser the Notes to be purchased by such Purchaser in the form of a single Note of each series to be purchased by such Purchaser (or such greater number of Notes in denominations of at least $100,000 as such Purchaser may request) dated the Closing Date and registered in such Purchaser’s name (or in the name of its nominee), against delivery by such Purchaser to the order of the Company of immediately available funds in the amount of the purchase price therefor by wire transfer of immediately available funds for the account of the Company to account number [__________], Wells Fargo Bank, 200 Lomas Blvd NW, Albuquerque, New Mexico 87102, ABA No. 121000248. If, at the Closing, the Company shall fail to tender such Notes to any Purchaser as provided above in this Section 3, or any of the conditions specified in Section 4 shall not have been fulfilled to such Purchaser’s satisfaction, such Purchaser shall, at its election, be relieved of all further obligations under this Agreement, without thereby waiving any rights such Purchaser may have by reason of such failure or such nonfulfillment.

The Company’s obligation to issue and sell to each Purchaser the Notes to be sold to such Purchaser at the Closing is subject to and conditioned upon the consummation of the TECO Acquisition on or before the Closing Date. Notwithstanding anything to the contrary in this Agreement, in the event that the Stock Purchase Agreement, dated as of May 25, 2013, by and among TECO, the Company and Continental Energy Systems LLC (the “TECO Acquisition Agreement”) shall be terminated for any reason prior to the consummation of the TECO Acquisition, this Agreement shall terminate and shall forthwith become void and be of no force and effect, without any liability on the part of any party (including, without limitation, with respect to the representations and warranties of the Company contained in this Agreement and any and all information contained in the Memorandum or any other Disclosure Documents or otherwise), and the Purchasers and the Company and their respective affiliates shall each be permanently and irrevocably relieved of all obligations and liabilities under this Agreement.

Each Purchaser’s obligation to purchase and pay for the Notes to be sold to such Purchaser at the Closing is subject to the fulfillment to such Purchaser’s satisfaction, prior to or at the Closing, of the following conditions:

The representations and warranties of the Company contained in this Agreement, and the representations and warranties of each Obligor in the other Finance Documents shall be correct when made and on the Closing Date.

After giving effect to the issue and sale of the Notes (and the application of the proceeds thereof as contemplated by Section 5.14), no Default or Event of Default shall have occurred and be continuing.

(a)Officer’s Certificate. The Company shall have delivered to such Purchaser an Officer’s Certificate, dated the Closing Date, certifying that the conditions specified in Sections 4.1, 4.2 and 4.10 have been fulfilled.

(b)Secretary’s Certificate. The Company shall have delivered to such Purchaser a certificate of its Secretary or Assistant Secretary, dated the Closing Date, (i) attaching a certified copy of the articles of incorporation of the Company and a true and correct copy of the by-laws of the Company, (ii) certifying as to the resolutions attached thereto and other corporate or equivalent proceedings relating to the authorization, execution and delivery of this Agreement and the Notes, and (iii) certifying the names and true signatures of the officers of the Company authorized to sign the Finance Documents to which the Company is a party.

Such Purchaser shall have received opinions in form and substance satisfactory to such Purchaser, dated the Closing Date (a) from Edwards Wildman Palmer LLP, special counsel for the Company, in the form set forth in Exhibit 4.4(a) (and the Company hereby instructs its counsel to deliver such opinion to the Purchasers), (b) from Bingham McCutchen LLP, the Purchasers’ special counsel in connection with such transactions, in the form set forth in Exhibit 4.4(b), (c) from Keleher & McLeod, P.A., special New Mexico counsel for the Company, in substantially the form set forth in Exhibit 4.4(c) and otherwise in form and substance reasonably satisfactory to the Purchasers (and the Company hereby instructs its counsel to deliver such opinion to the Purchasers), and (d) from Steptoe & Johnson LLP, special regulatory counsel for the Company, in the form set forth in Exhibit 4.4(d) (and the Company hereby instructs its counsel to deliver such opinion to the Purchasers).

Such Purchaser shall have received a fully executed copy of the NMGC Credit Agreement and all agreements executed pursuant thereto, including all amendments or other modifications to each of the foregoing, accompanied by an Officer’s Certificate (which certificate shall become effective immediately following the consummation of the TECO Acquisition) certifying that such copies are true, correct and complete copies thereof and that the NMGC Credit Agreement is in full force and effect.

On the Closing Date such Purchaser’s purchase of Notes shall (a) be permitted by the laws and regulations of each jurisdiction to which such Purchaser is subject, without recourse to provisions (such as section 1405(a)(8) of the New York Insurance Law) permitting limited investments by insurance companies without restriction as to the character of the particular investment, (b) not violate any applicable law or regulation (including, without limitation, Regulation T, U or X of the Board of Governors of the Federal Reserve System) and (c) not subject such Purchaser to any tax, penalty or liability under or pursuant to any applicable law or regulation, which law or regulation was not in effect on the date hereof. If requested by such Purchaser in advance of the Closing Date, such Purchaser shall have received an Officer’s Certificate certifying as to such matters of fact as such Purchaser may reasonably specify to enable such Purchaser to determine whether such purchase is so permitted.

Contemporaneously with the Closing the Company shall sell to each other Purchaser (or to other Persons substituted therefor pursuant to Section 21 or as otherwise arranged by the Company; provided that such Person is not an Affiliate of the Company) and each other Purchaser (or Person) shall purchase the Notes to be purchased by it at the Closing as specified in Schedule A.

Without limiting the provisions of Section 15.1, the Company shall have paid on the Closing Date the fees, charges and disbursements of the Purchasers’ special counsel referred to in Section 4.4 to the extent reflected in a statement of such counsel rendered to the Company at least two Business Days prior to the Closing Date.

A Private Placement Number issued by Standard & Poor’s CUSIP Service Bureau (in cooperation with the SVO) shall have been obtained for each series of the Notes.

The Company shall not have changed its jurisdiction of incorporation or organization, as applicable, or been a party to any merger or consolidation or succeeded to all or any substantial part of the liabilities of any other entity, at any time following the date of the most recent financial statements referred to in Schedule 5.5.

At least two Business Days prior to the date of the Closing, each Purchaser shall have received written instructions signed by a Responsible Officer on letterhead of the Company confirming the information specified in Section 3 including (i) the name and address of the transferee bank, (ii) such transferee bank’s ABA number and (iii) the account name and number into which the purchase price for the Notes is to be deposited.

Such Purchaser shall have received a fully executed copy of each of the 2011 Note Purchase Agreement and the 2011 NPA Amendment, accompanied by an Officer’s Certificate certifying that such copies are true, correct and complete copies thereof and that the 2011 Note Purchase Agreement is in full force and effect (it being understood that the effectiveness of the 2011 NPA Amendment shall be subject to the satisfaction or waiver of the conditions precedent set forth therein).

Such Purchaser shall have received evidence reasonably satisfactory to it that (a) all conditions precedent to the consummation of the TECO Acquisition (other than payment of the purchase price therefor) shall have been satisfied and that the TECO Acquisition shall be consummated substantially concurrently with the Closing and (b) following the consummation of the TECO Acquisition, TECO shall own, directly or indirectly, 100% of the outstanding Equity Interests of the Company.

Such Purchaser shall have received fully executed pay-off letters, in form and substance satisfactory to such Purchaser, evidencing that (a) all amounts under the Existing Credit Agreements shall be paid in full substantially concurrently with the Closing, and (b) that upon such payment, all commitments of the lenders thereunder shall be terminated and all Liens securing the Indebtedness thereunder shall be terminated or released.

All corporate and other proceedings in connection with the transactions contemplated by this Agreement and all documents and instruments incident to such transactions shall be satisfactory to such Purchaser and its special counsel, and such Purchaser and its special counsel shall have received all such counterpart originals or certified or other copies of such documents as such Purchaser or such special counsel may reasonably request.

The Company is a corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company has the corporate power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, and to execute, deliver, and perform its Obligations under the Finance Documents to which it is a party.

The Finance Documents have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof, each Note for which the Company has received payment in full and each other Finance Document will constitute, a legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

TECO, through its agent, Morgan Stanley & Co. LLC, has delivered to each Purchaser a copy of the Confidential Information Memorandum, dated July 2014 (the “Memorandum”), relating to the transactions contemplated hereby. The Memorandum fairly describes, in all material respects, the general nature of the business and principal properties of the Company and its Subsidiaries. This Agreement, the Memorandum and the documents, certificates or other writings (including supplements thereto) delivered to the Purchasers by or on behalf of the Company in connection with the transactions contemplated hereby and identified in Schedule 5.3, and the financial statements listed in Schedule 5.5 (this Agreement, the Memorandum and such documents, certificates or other writings and such financial statements delivered to each Purchaser prior to July 17, 2014 being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made. Except as disclosed in the Disclosure Documents, since December 31, 2013, there has been no change in the financial condition, operations, business, properties or prospects of the Company or any Subsidiary, except changes that, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

(a)Schedule 5.4 contains (except as noted therein) complete and correct lists of (i) the Company’s Subsidiaries, showing, as to each Subsidiary, the name thereof, the jurisdiction of its organization, and the percentage of shares of each class of its capital stock or similar Equity Interests outstanding owned by the Company and each other Subsidiary, and (ii) the Company’s directors and senior officers.

(b)All of the outstanding shares of capital stock or similar Equity Interests of each Subsidiary shown in Schedule 5.4 as being owned by the Company and its Subsidiaries have been validly issued, are fully paid and non-assessable and are owned by the Company or another Subsidiary free and clear of any Lien that is prohibited by this Agreement.

(c)Each Subsidiary is a corporation or other legal entity duly organized, validly existing and, where applicable, in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or other legal entity and, where applicable, is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each such Subsidiary has the corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact.

(d)No Subsidiary is subject to any legal, regulatory, contractual or other restriction (other than the agreements listed on Schedule 5.4 and customary limitations imposed by corporate law or similar statutes) restricting the ability of such Subsidiary to pay dividends out of profits or make any other similar distributions of profits to the Company or any of its Subsidiaries that owns outstanding shares of capital stock or similar Equity Interests of such Subsidiary.

The Company has delivered to each Purchaser copies of the financial statements of the Company and its Subsidiaries listed on Schedule 5.5. All of said financial statements (including in each case the related schedules and notes) fairly present in all material respects the consolidated financial position of the Company and its Subsidiaries as of the respective dates thereof and the consolidated results of their operations and cash flows for the respective periods indicated and have been prepared in accordance with GAAP consistently applied throughout the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments). The Company and its Subsidiaries do not have any Material off-balance sheet items that are not disclosed on such financial statements or otherwise disclosed in the Disclosure Documents.

The execution, delivery and performance by the Company of this Agreement and the Notes and the consummation of the transactions contemplated herein will not (a) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Company or any Subsidiary under, any indenture, mortgage, deed of trust, loan agreement, purchase or credit agreement, lease, corporate charter or by-laws, or any other agreement or instrument to which the Company or any Subsidiary is bound or by which the Company or any Subsidiary or any of their respective properties may be bound or affected (other than such breach or default as may have been waived or otherwise approved pursuant to such indenture, mortgage, deed of trust, loan agreement, purchase or credit agreement, lease, corporate charter or by-laws, or any other agreement or instrument), (b) except as set forth on Schedule 5.7, conflict with or result in a

breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to the Company or any Subsidiary or (c) except as set forth on Schedule 5.7, violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company or any Subsidiary.

No consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority is required in connection with the execution, delivery or performance by, or enforcement against, the Company of this Agreement or the Notes, other than (a) as have been obtained or made on or prior to the Closing Date, and (b) as otherwise set forth on Schedule 5.7 hereto.

(a)Except as disclosed in Schedule 5.8, there are no actions, suits, investigations or proceedings pending or, to the knowledge of the Company, threatened against or affecting the Company or any Subsidiary or any property of the Company or any Subsidiary in any court or before any arbitrator of any kind or before or by any Governmental Authority that, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

(b)Neither the Company nor any Subsidiary is in default under any term of any agreement or instrument to which it is a party or by which it is bound, or any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority or is in violation of any applicable law, ordinance, rule or regulation (including without limitation Environmental Laws and any of the laws and regulations referred to in Section 5.16) of any Governmental Authority, which default or violation, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

Except as disclosed in Schedule 5.9, the Company and its Subsidiaries have filed all material tax returns that are required to have been filed in any jurisdiction or has requested extensions thereof, and has paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent (taking into account any applicable extensions), except for any taxes and assessments (a) the failure of which to pay could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or (b) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Company or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. The charges, accruals and reserves on the books of the Company and its Subsidiaries in respect of Federal, state or other taxes for all fiscal periods are adequate. The Federal income tax liabilities of the Company and its Subsidiaries have been finally determined (whether by reason of completed audits or the statute of limitations having run) for all Fiscal Years up to and including the Fiscal Year ended December 31, 2009.

The Company and its Subsidiaries have good and sufficient title to their respective properties that individually or in the aggregate are Material, including all such properties reflected in the most recent audited balance sheet referred to in Section 5.5 or purported to have been acquired by the Company or any Subsidiary after said date (except as sold or otherwise disposed of in the ordinary course of business), in each case free and clear of Liens prohibited by this Agreement. All leases that, individually or in the aggregate are Material are valid and subsisting and are in full force and effect in all material respects.

(a)Except as disclosed in Schedule 5.11, the Company and its Subsidiaries own or possess all licenses, permits, franchises, authorizations, patents, copyrights, proprietary software, service marks, trademarks and trade names, or rights thereto, that individually or in the aggregate are Material, without known conflict with the rights of others.

(b)To the knowledge of the Company, neither the Company nor any Subsidiary is infringing in any Material respect any license, permit, franchise, authorization, patent, copyright, proprietary software, service mark, trademark, trade name or other right owned by any other Person.

(c)To the knowledge of the Company, there is no Material violation by any Person of any right of the Company or any of its Subsidiaries with respect to any patent, copyright, proprietary software, service mark, trademark, trade name or other right owned or used by the Company or any of its Subsidiaries.

(a)The Company and each ERISA Affiliate have operated and administered each Plan (other than a Multiemployer Plan) in compliance with the applicable provisions of ERISA and the Code except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in section 3 of ERISA) (other than liabilities for accrued benefits or required PBGC premium payments arising in the ordinary course of business), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to section 430 or 436 of the Code or section 4068 of ERISA, other than such liabilities or Liens as could not be individually or in the aggregate Material.

(b)The present value of the aggregate benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan’s most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan’s most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities by more than an amount, either in the case of any single such Plan or in the aggregate for all such Plans, that could reasonably be expected to result in a Material Adverse Effect. The term “benefit liabilities” has the meaning specified in section 4001 of ERISA and the terms “current value” and “present value” have the meaning specified in section 3 of ERISA.

(c)The Company and its ERISA Affiliates have not incurred withdrawal liabilities under section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material. The contingent liability of the Company and its ERISA Affiliates for a withdrawal from each Multiemployer Plan, individually or when aggregated with the contingent liabilities for withdrawals from all such Multiemployer Plans, could not reasonably be expected to result in a Material Adverse Effect.

(d)Other than as set forth in Schedule 5.12, the Company and its Subsidiaries have no Material accumulated postretirement benefit obligations (determined as of the last day of the Company’s most recently ended Fiscal Year in accordance with Financial Accounting Standards Board Accounting

Standards Codification Section 715-60 (without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code)).

(e)The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder does not constitute a “prohibited transaction” under section 406(a) of ERISA or in connection with which a tax could be imposed pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation by the Company to each Purchaser in the first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy of such Purchaser’s representation in Section 6.2 as to the sources of the funds used to pay the purchase price of the Notes to be purchased by such Purchaser.

Neither the Company nor anyone acting on its behalf has offered the Notes or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any person other than not more than eighty Institutional Investors (as defined in clause (c) to the definition of such term), including the Purchasers, each of which has been offered the Notes at a private sale for investment.

Each Purchaser represents that such Purchaser has had the opportunity to ask questions of the Company and received answers concerning the terms and conditions of the sale of the Notes. Each Purchaser is able to fend for itself in the transactions contemplated by the Memorandum. The financial position of each Purchaser is such that it can afford to bear the economic risk of holding the Notes. Each Purchaser can afford to suffer the complete loss of its investment in the Notes. The knowledge and experience of each Purchaser in financial and business matters is such that it is capable of evaluating the merits and risks of the investment in the Notes. Each Purchaser acknowledges that no representations, express or implied, are being made with respect to the Company, any Subsidiaries, the Notes or otherwise, other than those expressly set forth herein, in any other Finance Document or contemplated hereby.

(d)Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.3 shall be made on the Proposed Prepayment Date at 100% of the principal amount of such Notes, together with accrued and unpaid interest on such Notes accrued to the date of prepayment, but, in any case, without any Make-Whole Amount.

(e)Officer’s Certificate. Each offer to prepay the Notes pursuant to this Section 8.3 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 to this Section 8.3 and that failure by a holder to respond to such offer by the deadline established in Section 8.3(c) shall result in such offer to such holder being deemed rejected; (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 8.3 have been fulfilled; and (vi) in reasonable detail, the nature and date of the Change of Control.

(f)Notice Concerning Status of Holders of Notes. Promptly after the Proposed Prepayment Date and the making of all prepayments contemplated on such Proposed Prepayment Date under this Section 8.3 (and, in any event, within 30 days thereafter), the Company shall deliver to each then current holder of Notes, if any, a certificate signed by a Senior Financial Officer of the Company containing a list of the then current holders of Notes (together with their addresses) and setting forth as to each such holder the outstanding principal amount of Notes held by such holder at such time.

(g)Other Considerations. Notwithstanding Section 8.3(a), the Company shall not be required to make the offer to prepay made pursuant to this Section 8.3 upon a Change of Control if (i) a third party makes such an offer contemporaneously with or upon a Change of Control in compliance with the requirements of this Agreement for such an offer made by the Company and such third party purchases all Notes validly tendered and not withdrawn under such offer or (ii) a notice of prepayment has been given pursuant to Section 8.2 to prepay all of the outstanding Notes. Any offer to prepay made pursuant to this Section 8.3 may be made in advance of a Change of Control, conditional upon the occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making such an offer; provided that such prepayment must be made on or prior to the Proposed Prepayment Date specified in any offer to prepay the Notes pursuant to clause (i) above or the date fixed for prepayment pursuant to clause (ii) above, or thereafter any holder of Notes shall have the right to withdraw any Notes tendered in response to such offer to prepay the Notes pursuant to this clause (g).

In the case of each partial prepayment of the Notes pursuant to Section 8.2, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes (regardless of series) at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment.

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 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.

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 except (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes or (b) pursuant to an offer to purchase made by the Company or an Affiliate pro rata to the holders of all Notes at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 20 Business Days. The Company will promptly cancel all Notes acquired by it or by any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

The term “Make-Whole Amount” means, with respect to any 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 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 Note, the principal of such 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 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 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 Note, 0.50% over the yield to maturity implied by (i) the yields 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 having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series 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 such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.

In the case of each determination under clause (i) or clause (ii), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the most recently issued actively traded on the run U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the most recently issued actively traded on the run U.S. Treasury security with the maturity 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.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) 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 (calculated to the nearest one-twelfth year) 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 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 terms of the 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 8.2 or Section 12.1.

“Settlement Date” means, with respect to the Called Principal of any 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.

The Company covenants that following the Closing and for so long as any of the Notes are outstanding:

Without limiting Section 10.6, the Company will, and will cause each of its Subsidiaries to, comply with all Laws, orders, writs, injunctions and decrees, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, ERISA, the USA Patriot Act, Environmental Laws and the other laws and regulations referred to in Section 5.16, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such Laws, orders, writs, injunctions and decrees, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

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 are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated.

The Company will, and will cause each of its Subsidiaries to, (a) maintain, preserve and protect, or cause to be maintained, preserved and protected, all of its properties and equipment necessary in the operation of its business in good working order and condition, (other than ordinary wear and tear and damage by fire or other casualty or taking by condemnation), (b) make all necessary repairs thereto and renewals and replacements thereof, and (c) use the standard of care typical in the industry in the operation and maintenance of its facilities, except, in the case of clauses (a), (b) and (c) above, where the failure to do so could not reasonably be expected to have a Material Adverse Effect; provided that this Section 9.3 shall not prevent the Company or any Subsidiary from discontinuing the operation and maintenance of any of its properties if such discontinuance is desirable in the conduct of its business and the Company has concluded that such discontinuance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

The Company will, and will cause each of its Subsidiaries to, file all material 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 imposed on them or any of their properties, assets, income or franchises, to the extent the same have become due and payable and before they have become

delinquent (taking into account any applicable extensions) and all claims for which sums have become due and payable that have or might become a Lien on properties or assets of the Company or any of its Subsidiaries, provided that neither the Company nor any Subsidiary need pay any such tax, assessment, charge, levy or claim 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, levies and claims in the aggregate could not reasonably be expected to have a Material Adverse Effect.

Subject to Section 10.2, the Company will at all times preserve and keep in full force and effect its corporate existence and the corporate or other applicable existence of each of its Subsidiaries (unless merged into the Company or another Subsidiary) and all rights, privileges, permits, licenses 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 or other applicable existence, right, privilege, permit, license or franchise could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

The Company will, and will cause each of its Subsidiaries to, maintain books of record and account in conformity with GAAP and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over the Company or such Subsidiary, as the case may be.

(a)The Company will cause each Non-Regulated Subsidiary that is or becomes a borrower or guarantor under or in respect of any Principal Credit Facility to become a Guarantor, prior to or concurrently with so becoming a borrower or a guarantor as aforesaid, by causing such Person (a “Guarantor”), at the Company’s expense, to execute and/or deliver to each holder of Notes, to the extent not prohibited by applicable law:

(i)(A) a Guaranty Agreement in substantially the form of Exhibit 9.7 hereto (or a Joinder Agreement to such Guaranty Agreement in substantially the form of Exhibit A thereto) pursuant to which such Subsidiary shall agree, inter alia, to guarantee the Obligations, or (B) a guarantee agreement otherwise in form and substance reasonably satisfactory to the Required Holders;

(ii)copies of the Organizational Documents of such Guarantor, resolutions of the board of directors (or other similar governing body) of such Guarantor authorizing its execution and delivery of the Subsidiary Guaranty by such Guarantor and the transactions contemplated thereby, and specimen signatures of authorized officers of such Guarantor (in each case, certified as correct and complete copies by the secretary or an assistant secretary (or an equivalent officer) of such Guarantor); and

(iii)an opinion of counsel to such Guarantor with respect to the Subsidiary Guaranty executed by such Guarantor, which opinion may be subject to customary qualifications and limitations, to the effect that: (A) the applicable Subsidiary Guaranty has been duly executed and authorized, (B) such Subsidiary Guaranty constitutes a valid, binding and enforceable obligation of such Guarantor, except insofar as enforcement thereof may be limited by bankruptcy,

insolvency or similar laws (including, without limitation, all laws relating to fraudulent transfers) and except insofar as enforcement thereof is subject to general principles of equity and (C) except as could not reasonably be expected to result in a Material Adverse Effect, the execution, delivery and performance by the Guarantor of the Subsidiary Guaranty will not (1) contravene, result in any breach of, or constitute a default under any corporate charter or by-laws or similar organizational documents of such Guarantor, (2) conflict with or result in a breach of the express terms or conditions of material Indebtedness of the Company or such Guarantor, or (3) violate any provision of any Federal or state (which may be limited to the state(s) in which such counsel is admitted to practice) statute or other rule or regulation.

(b)Upon (i) delivery to the Company of a consent executed by the Required Holders with respect to a Guarantor (but subject to the provisions of Section 17.2(c) hereof), (ii) any sale, exchange or transfer (by merger or otherwise) of the Capital Stock of a Guarantor, after which such Guarantor is no longer a Non-Regulated Subsidiary or a Permitted Joint Venture, or (iii) the sale or disposition of all the assets of such Guarantor, which sale, exchange, transfer or disposition is made in compliance with the applicable provisions of Section 10.2 (but only if such Guarantor will not be a borrower or guarantor of obligations outstanding under any Principal Credit Facility after giving effect to such transaction), such Person shall automatically be released as a Guarantor under the Subsidiary Guaranty to which it is a party with effect from the date of such event under clause (i), (ii) or (iii), as applicable.

(c)The Company will not cause or permit any Regulated Subsidiary to become a borrower or guarantor under or in respect of any Principal Credit Facility.

The Company and the Guarantors will execute and deliver such further documentation and take such further action as may be reasonably necessary or proper to carry out the provisions and purposes of this Agreement, the Notes and the Subsidiary Guaranties.

The Company covenants that following the Closing and for so long as any of the Notes are outstanding:

The Company will not, and will not permit any of its Subsidiaries to, enter into any transaction or series of transactions with any Affiliate other than on terms and conditions substantially as favorable to the Company or such Subsidiary as would be obtainable by the Company or such Subsidiary at the time in a comparable arm’s length transaction with a Person other than an Affiliate, provided that the foregoing restrictions shall not apply to (a) transactions set forth in Schedule 10.1 hereto, (b) employment arrangements entered into in the ordinary course of business with employees and officers of the Company and its Subsidiaries, (c) customary fees paid or other compensation arrangements provided to members of the board of directors (or other similar governing body) of the Company and of its Subsidiaries, (d) consulting services to Permitted Joint Ventures and any other transactions between or among the Company and its Subsidiaries and Permitted Joint Ventures in the ordinary course of business, and (e) transactions between or among any of the Company and its Subsidiaries.

The Company will not, and will not permit any of its Subsidiaries to, consolidate with or merge with any other Person or convey, transfer, sell or lease all or substantially all of its assets in a single transaction or series of transactions to any Person, unless:

(a)if the Company (with respect to any transaction involving the Company) or such Subsidiary (with respect to any transaction not involving the Company) is not the successor formed by such consolidation or the survivor of such merger or the Person that acquires by conveyance, transfer, sale or lease all or substantially all of the assets of the Company or such Subsidiary as an entirety, as the case may be, such successor, survivor or Person, as applicable, is a solvent corporation or limited liability company organized and existing under the laws of the United States or any State thereof (including the District of Columbia), and:

(i)such corporation or limited liability company shall have executed and delivered to each holder of any Notes its assumption (which assumption shall, in each case, be satisfactory in form and substance to the Required Holders) of the due and punctual performance and observance of each covenant and condition of (A) in the case of any such transaction involving the Company, this Agreement and the Notes, and (B) in the case of any such transaction involving a Subsidiary that is a Guarantor, the Subsidiary Guaranty to which such Guarantor is a party; and

(ii)such corporation or limited liability company shall have caused to be delivered to each holder of any Notes an opinion of nationally recognized independent counsel, or other independent counsel reasonably satisfactory to the Required Holders in customary form (and subject to customary exceptions and qualifications), to the effect that all agreements or instruments effecting such assumption are enforceable in accordance with their terms;

(b)each Guarantor (if any) shall have reaffirmed its obligations under the Subsidiary Guaranty to which it is a party; and

(c)immediately before and immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing.

(b)Liens in respect of property or assets of the Company or any of its Subsidiaries imposed by law which were incurred in the ordinary course of business, such as carriers’, warehousemen’s and mechanics’ Liens, statutory landlord’s Liens, and other similar Liens arising in the ordinary course of business, and (i) which do not in the aggregate materially detract from the value of such property or assets or materially impair the use thereof in the operation of the business of the Company or any

(u)Liens securing Indebtedness of the Company or any Subsidiary not otherwise permitted by clauses (a) through (t), inclusive, of this Section 10.4, provided that the outstanding principal amount of Priority Debt does not at any time exceed 10% of Consolidated Total Assets (determined as of the end of the then most recently ended Fiscal Quarter for which financial statements have been provided, and pro forma to give effect to any acquisitions and dispositions of a business group, division or business unit (or of a Person engaged therein) consummated since the end of such Fiscal Quarter).

Notwithstanding anything contained in this Section 10.4 (including, without limitation, Section 10.4(u)), the Company shall not, and shall not permit any Subsidiary to, create, incur, assume or suffer to exist any Lien on any property securing Indebtedness outstanding or issued under any Principal Credit Facility, unless and until all Obligations shall be concurrently secured with such property equally and ratably with such Indebtedness pursuant to an agreement or agreements reasonably acceptable to the Required Holders.

The Company will not at any time permit the outstanding amount of Priority Debt to exceed 10% of the Consolidated Total Assets (determined as of the end of the then most recently ended Fiscal Quarter for which financial statements have been provided, and pro forma to give effect to any acquisitions and dispositions of a business group, division or business unit (or of a Person engaged therein) consummated by the Company or any of its Subsidiaries since the end of such Fiscal Quarter).

The Company will not, and will not permit any Subsidiary to, consummate any Asset Sale, unless, after giving effect to such proposed Asset Sale, the aggregate value of all assets of the Company and its Subsidiaries (valued at the greater of net book value or fair value) that were the subject of an Asset Sale during the period commencing on the first day of the then current Fiscal Year of the Company and ending on the date of such proposed Asset Sale does not exceed 10% of Consolidated Total Assets determined as at the last day of the then most recently ended Fiscal Year of the Company preceding such Asset Sale; provided, however, that for purposes of the foregoing calculation above, there shall not be included the value of any assets which were the subject of an Asset Sale if the Net Proceeds from such Asset Sale are applied by the Company within 360 days after the receipt of such Net Proceeds either (i) to make an investment in Additional Assets having a fair market value (as determined in good faith by the Board of Directors of the Company) at least equal to that of the assets so disposed of, or (ii) to the repayment or prepayment of unsubordinated Indebtedness of the Company (other than (x) Indebtedness owing by the Company to any of its Subsidiaries or any Affiliate and (y) Indebtedness in respect of any revolving credit or similar facility providing the Company or any such Subsidiary with the right to obtain loans or other extensions of credit from time to time, unless in connection with such payment of Indebtedness, the availability of credit under such credit facility is permanently reduced by an amount not less than the amount of such proceeds applied to the payment of such Indebtedness).

The Company will not, and will not permit any Subsidiary to, engage in any business if, as a result, the general nature of the business in which the Company and its Subsidiaries, taken as a whole, would then be engaged would be substantially changed from the general nature of the business in which the Company and its Subsidiaries, taken as a whole, are engaged on the date of this Agreement as described in the Memorandum.

The Company will not, and will not permit any Subsidiary to, make or declare, directly or indirectly, any Restricted Payment, or incur any obligation (contingent or otherwise) to do so, unless no Specified Default shall

have occurred and be continuing at the time of any such Restricted Payment or would result therefrom. Notwithstanding the foregoing:

(a)each Subsidiary may make Restricted Payments to (i) the Company, (ii) any Subsidiaries of the Company that are Guarantors and (iii) any other Person that owns a direct Equity Interest in such Subsidiary, ratably according to their respective holdings of the type of Equity Interest in respect of which such Restricted Payment is being made; and

(b)the Company and each Subsidiary may declare and make dividend payments or other distributions payable solely in the common stock or other common Equity Interests of such Person.

The Company will not permit the ratio of Consolidated Total Debt to Consolidated Total Capitalization, determined as of the last day of each Fiscal Quarter of the Company, to exceed 0.65 to 1.00.

An “Event of Default” shall exist if any of the following conditions or events shall occur and/or be continuing after the Closing:

(d)the Company defaults in the performance of or compliance with any term contained in Sections 10.1, 10.2, 10.4, 10.6, 10.7 or 10.8 and such default is not remedied within 5 days after the earlier of (i) a Responsible Officer obtaining actual knowledge of such default and (ii) the Company receiving written notice of such default from the Required Holders (any such written notice to be identified as a “notice of default” and to refer specifically to this Section 11(d)); or

(e)any Obligor defaults in the performance of or compliance with any term contained in any Finance Document (other than those referred to in Sections 11(a), (b), (c) and (d)) and such default is not remedied within 30 days after after the earlier of (i) a Responsible Officer obtaining actual knowledge of such default and (ii) the Company receiving written notice of such default from the Required Holders (any such written notice to be identified as a “notice of default” and to refer specifically to this Section 11(e)); or

(f)any representation or warranty made in writing by or on behalf of any Obligor or by any officer of any Obligor in any Finance Document or in any writing furnished in connection with the transactions contemplated hereby proves to have been false or incorrect in any material respect on the date as of which made; or

As used in Section 11(k), the terms “employee benefit plan” and “employee welfare benefit plan” shall have the respective meanings assigned to such terms in section 3 of ERISA.

(a)If an Event of Default with respect to an Obligor described in Section 11(h) or (i) (other than an Event of Default described in clause (i) of Section 11(h) or described in clause (vi) of Section 11(h) by virtue of the fact that such clause encompasses clause (i) of Section 11(h)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable.

(b)If any other Event of Default has occurred and is continuing, the Required Holders may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable.

(c)If any Event of Default described in Section 11(a) or (b) has occurred and is continuing, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable.

Upon any Notes becoming due and payable under this Section 12.1, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, but not limited to, interest accrued thereon at the Default Rate) and, (y) the Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law) shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for the payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

If any Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity

or other appropriate proceeding, whether for the specific performance of any agreement contained herein, in any Note or any other Financing Document, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

At any time after any Notes have been declared due and payable pursuant to Section 12.1(b) or (c), the Required Holders, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) neither the Company nor any other Person shall have paid any amounts which have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and (d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon.

No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or remedy conferred by this Agreement, by any Note or any other Finance Document upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

Following the Closing, the Company shall keep at its principal executive office a register for the registration and registration of transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders of Notes.

Upon surrender of any Note to the Company at the address and to the attention of the designated officer (all as specified in Section 18(iii)), for registration of transfer or exchange (and in the case of a surrender for registration of transfer accompanied by a written instrument of transfer duly executed by the registered holder of such Note or such holder’s attorney duly authorized in writing and accompanied by the relevant name, address and other information for notices of each transferee of such Note or part thereof), within ten Business Days thereafter, the Company shall execute and deliver, at the Company’s expense (except as provided below),

one or more new Notes of the same series (as requested by the holder thereof) as such surrendered Note in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1(a) or Exhibit 1(b), as applicable. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in denominations of less than $100,000, provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes of a series, one Note of such series may be in a denomination of less than $100,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representations set forth in Section 6 (except that it shall not be deemed to have made the representation set forth in the first sentence of Section 6.3 or to have represented pursuant to Section 6.1 that it has acquired Notes for investment and not with a view to the distribution thereof).

Upon receipt by the Company at the address and to the attention of the designated officer (all as specified in Section 18(iii)) of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and

(a)in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least $25,000,000 or a Qualified Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or

within ten Business Days thereafter, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note of the same series, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

Subject to Section 14.2, payments of principal, Make-Whole Amount, if any, and interest becoming due and payable on the Notes shall be made in New York, New York at the principal office of JPMorgan Chase Bank, National Association in such jurisdiction. The Company may at any time, by notice to each holder of a Note, change the place of payment of the Notes so long as such place of payment shall be either the principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such jurisdiction.

So long as any Purchaser or its nominee shall be the holder of any Note, and notwithstanding anything contained in Section 14.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, and interest by the method and at the address specified for such purpose below such Purchaser’s name in Schedule A, or by such other method or at such other address as

such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 14.1. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such 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 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 under this Agreement and that has made the same agreement relating to such Note as the Purchasers have made in this Section 14.2.

If and only if the Closing occurs and the Notes are issued pursuant hereto, the Company will pay all costs and expenses (including reasonable attorneys’ fees of one special counsel and, if reasonably required by the Required Holders, one local counsel in each relevant jurisdiction) incurred by the Purchasers and each other holder of a Note in connection with such transactions, and in connection with any amendments, waivers or consents under or in respect of this Agreement, the Notes or any other Finance Document (whether or not such amendment, waiver or consent becomes effective), including, without limitation: (a) the reasonable costs and expenses incurred in enforcing or defending (or determining whether or how to enforce or defend) any rights under this Agreement, the Notes or any other Finance Document or in responding to any subpoena or other legal process or informal investigative demand issued in connection with this Agreement, the Notes or any other Finance Document, or by reason of being a holder of any Note, (b) the costs and expenses, including financial advisors’ fees, incurred in connection with the insolvency or bankruptcy of the Company or any Guarantor or in connection with any work-out or restructuring of the transactions contemplated hereby and by the Notes and the other Finance Documents and (c) the costs and expenses incurred in connection with the initial filing of this Agreement and all related documents and financial information with the SVO, provided that such costs and expenses under this clause (c) shall not exceed $5,000. If and only if the Closing occurs and the Notes are issued pursuant hereto, the Company will pay, and will save each Purchaser and each other holder of a Note harmless from, all claims in respect of any fees, costs or expenses, if any, of brokers and finders (other than those, if any, retained by a Purchaser or other holder in connection with its purchase of the Notes).

The obligations of the Company under this Section 15 will survive the payment or transfer of any Note, the enforcement, amendment or waiver of any provision of this Agreement, the Notes and the other Finance Documents, and the termination of this Agreement. Notwithstanding the foregoing, the obligations of the Company under this Section 15 shall terminate and shall forthwith become void and be of no force and effect if the Closing does not occur, in accordance with Section 3 of this Agreement.

All representations and warranties contained herein shall survive the execution and delivery of this Agreement and the Notes, the purchase or transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of such Purchaser or any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to

this Agreement shall be deemed representations and warranties of the Company under this Agreement. Subject to the preceding sentence, this Agreement, the Notes and the other Finance Documents embody the entire agreement and understanding between each Purchaser and the Company and supersede all prior agreements and understandings relating to the subject matter hereof. Notwithstanding the foregoing, all representations and warranties contained herein shall terminate and shall forthwith become void and be of no force and effect if the Closing does not occur, in accordance with Section 3 of this Agreement.

This Agreement and the Notes and any other Finance Document may be amended, and the observance of any term hereof or of the Notes or of any other Finance Document may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of any of the provisions of Section 1, 2, 3, 4, 5, 6 or 21 hereof, or any defined term (as it is used therein), will be effective as to any Purchaser unless consented to by such Purchaser in writing, and (b) no such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Section 12 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or of the Make-Whole Amount on the Notes, (ii) change the percentage of the principal amount of the Notes the holders of which are required to consent to any such amendment or waiver, or (iii) amend any of Sections 8, 11(a), 11(b), 12, 17 or 20.

(a)Solicitation. The Company will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with notice 10 Business Days in advance of the date a decision is required, setting forth the principal terms of any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Notes or any other Finance Document. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 17 to each holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes.

(b)Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of Notes as consideration for or as an inducement to the entering into by any holder of Notes of any waiver or amendment of any of the terms and provisions hereof, of the Notes or of any other Financing Document unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each holder of Notes then outstanding even if such holder did not consent to such waiver or amendment.

(c)Consent in Connection with Transfer. Any consent made pursuant to this Section 17.2 by the holder of any Note that has transferred or has agreed to transfer such Note to the Company, any Subsidiary or any Affiliate of the Company (or any other Person in connection with, or in anticipation of, an acquisition of, tender offer for, or merger with, the Company) and has provided or has agreed to provide such written consent as a condition to such transfer shall be void and of no force or effect except solely as to such holder, and any amendments effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for such consent (and the consents of all other holders of Notes that were acquired under the same or similar conditions) shall be void and of no force or effect except solely as to such transferring holder.

Any amendment or waiver consented to as provided in this Section 17 applies equally to all 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 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 holder of such Note. As used herein, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented.

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 Agreement, the Notes or any other Finance Document, or have directed the taking of any action provided herein, in the Notes or in any other Finance Document 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 the Company or any of its Affiliates shall be deemed not to be outstanding.

All notices and communications provided for hereunder shall be in writing and sent (a) by telecopy 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 notice must be sent:

(i)if to any Purchaser or its nominee, to such Purchaser or nominee at the address specified for such communications in Schedule A, or at such other address as such Purchaser or nominee shall have specified to the Company in writing,

(ii)if to any other holder of any Note, to such holder at such address as such other holder shall have specified to the Company in writing, or

(iii)if to the Company, to the Company at 5120 Masthead, NE, Albuquerque, New Mexico 87109, Facsimile No. (505) 797-7901, Attention: Ryan Shell, Vice President, Controller & Treasurer, or at such other address as the Company shall have specified to the holder of each Note in writing.

This Agreement and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by any Purchaser at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information previously or hereafter furnished to any Purchaser, may be reproduced by such Purchaser by any photographic, photostatic, electronic, digital, or other similar process and such Purchaser may destroy any original document so reproduced. The Company agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Purchaser in

the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company or any other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.

For the purposes of this Section 20, “Confidential Information” means information delivered to any Purchaser by or on behalf of TECO, the Company or any of its Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Purchaser as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary or (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly available. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, officers, employees, agents, attorneys, trustees and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 20, (iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or offers to sell such Note or any part thereof or any participation therein (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), (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 federal or state regulatory authority having jurisdiction over such Purchaser, (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 investment portfolio, or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser’s Notes, this Agreement or the other Finance Documents. 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 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.

Each 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, by written notice to the Company, which notice shall be signed by both such Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Affiliate in lieu of such original Purchaser. In the event that such

Affiliate is so substituted as a Purchaser hereunder and such Affiliate thereafter transfers to such original 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” 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, and such original Purchaser shall again have all the rights of an original holder of the Notes under this Agreement.

All covenants and other agreements contained in this Agreement 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.

Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.2 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.

All accounting terms used herein which are not expressly defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement or any other Finance Document shall be made in accordance with GAAP and (ii) all financial statements shall be prepared in accordance with GAAP. Notwithstanding the foregoing, for purposes of determining compliance with Section 10.4, Section 10.5 and Section 10.10, or the determination of financial terms, contained in this Agreement, any election by the Company to measure an item of Indebtedness using fair value (as permitted by Financial Accounting Standards Board Accounting Standards Codification 825-10-25 - Fair Value Option (formerly known as FASB 159) or any similar accounting standard) shall be disregarded and such determination shall be made instead using the par value of such Indebtedness.

Any provision of this 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.

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 an express contrary provision) be deemed to excuse compliance with any other covenant. Where 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.

For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a part hereof.

This Agreement 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.

This 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.

(a)The Company irrevocably submits to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action or proceeding arising out of or relating to this Agreement or the Notes. To the fullest extent permitted by applicable law, the Company 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 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 holder 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 holder of a Note to serve process in any manner permitted by law, or limit any right that the 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 parties hereto hereby waive trial by jury in any action brought on or with respect to this Agreement, the Notes or any other document executed in connection herewith or therewith.

If you are in agreement with the foregoing, please sign the form of agreement on a counterpart of this Agreement and return it to the Company, whereupon this Agreement shall become a binding agreement between you and the Company.

New Mexico Gas Company, Inc. Audited Financial Statements, for the years ended December 31, 2013, 2012, 2011, 2010 and 2009

February 2011 Gas Shortages, System Emergencies, Curtailments of Service, and Related Litigation. On February 2 and 3, 2011, NMGC experienced gas shortages due to weather-related interruptions of electric service, weather-related problems on the systems of various interstate pipelines and in gas fields that are the sources of gas supplied to NMGC, and high weather-driven usage. This gas supply disruption resulted in the declaration of two system emergencies (first on the south segment of NMGC's system and then on the north segment of the system) by NMGC, causing involuntary curtailments of gas utility service to approximately 28,700 customers on February 3, 2011. Service restoration efforts commenced immediately after NMGC's transmission and distribution system stabilized on February 3, 2011, and service was restored to various areas of NMGC's system over the next week. Restoration efforts were essentially completed by February 8, 2011.

NMGC's tariff provides that NMGC is to be “held harmless for the loss of service to End-Users arising from curtailments executed in compliance with [NMGC’s curtailment rule].” NMGC believes that the events that led to the curtailment of service to customers qualify as system emergencies as defined in the curtailment rule and that it complied with the curtailment rule. NMGC will attempt to perfect that position before the NMPRC and in other venues, including in the litigation brought against NMGC described below.

Curtailment-related litigation. In March 2011, a customer purporting to represent a class consisting of all “32,000 [sic] customers” who had their gas utility service curtailed during the early-February system emergencies filed a putative class action lawsuit against NMGC. The complaint alleged negligence, breach of express and implied contract, and violation of the New Mexico Unfair Practices Act and sought compensatory damages, punitive damages, and treble damages pursuant to the Unfair Practices Act. Later in March 2011, the complaint was amended to name additional customers as class representatives and clarify certain jurisdictional issues.

In March 2011, the Town of Bernalillo, New Mexico, purporting to represent a class consisting of all “New Mexico municipalities and governmental entities who have suffered damages as a result of the natural gas utility shut off” filed a putative class action lawsuit against NMGC, four of its officers, and others. In July 2011, plaintiff filed an amended complaint added an additional plaintiff purporting to represent a class of all “similarly situated New Mexico private businesses and enterprises.” The amended complaint, like the original complaint, alleged negligence, breach of contract, and violation of the New Mexico Unfair Trade Practices Act and seeks compensatory damages, punitive damages, and treble damages pursuant to the Unfair Practices Act.

The two purported class actions have been consolidated, and venue has been moved to Sandoval County, New Mexico. NMGC has filed various motions in these cases, including motions for summary judgment on all claims. As necessary, NMGC also plans to assert various defenses to liability, including the protection against liability contained in NMGC’s tariff. The consolidated putative class actions are still pending. In February 2014, the Court in the consolidated actions granted motions to dismiss the negligence claims and unfair trade practices claims against NMGC and all remaining claims against the individual corporate officers and employees. The contract claim was dismissed subject to Plaintiffs’ opportunity to move to amend their complaints to plead a claim for breach of an implied contract subject to certain restrictions out by the Court, and subject to further motions to dismiss. Amended complaints were filed by both sets of Plaintiffs on March 14, 2014. NMGC has filed motions to strike or dismiss all claims asserted in the amended complaints which are pending.

On September 27, 2012, Allstate and approximately 16 other insurance carriers filed a subrogation lawsuit in Bernalillo County for monies paid to their insureds for broken pipes, water damage and other losses allegedly

sustained as a result of the curtailment of natural gas service during the February 3, 2011 gas outage event. The Complaint alleges negligence, negligence per se, and breach of contract and seeks an unspecified amount of damages. The matter is pending and discovery is proceeding.

On August 17, 2012, an individual customer filed suit for damages for property damage to home allegedly resulting from the February 2011 Outage. The Complaint alleges negligence and breach of contract and seeks unspecified damages. The matter is pending and discovery is proceeding.

NMGC’s self-insurance retention of $1 million has been satisfied, and insurance coverage of up to $135 million for all outage related lawsuits is available. NMGC does not believe there are any claims that are not covered.

While the outcome of the above is uncertain, the Company does not believe that the matters disclosed above could reasonably be expected to have a Material Adverse Effect.

Many of New Mexico Gas Company, Inc.’s (“NMGC”) transmission pipelines and distribution facilities are located on lands that require the grant of rights of way, leases or franchises (“ROW”) from governmental entities, Native American tribes and Pueblos, or private landowners. Transmission pipelines and distribution facilities, including 215 miles of transmission pipelines and a number of distribution mains, cross the lands of various Native American Tribes and Pueblos. The majority of these ROW are located near Albuquerque and Santa Fe and in the Espanola valley. Many of these ROW are now due for renewal. Several ROW have expired or will expire within the next few years. NMGC is in the process of negotiating renewals of these ROW, including, in some instances, leases instead of rights of way. Such leases or rights of way on Native American and Pueblo lands generally cover periods of 20 to 25 years, with the costs of the leases or rights of way typically paid in advance. The amounts paid for leases or rights of way are amortized over the periods covered by these property interests.

NMGC spent $0.1 million and $0.3 million renewing ROW in 2013 and 2012, respectively. Aggregate expenditures for ROW during the period 2014 through 2017 are estimated to be between $13 and $14 million. The timing of ROW expenditures during this four-year period is dependent on many factors, including the pace of negotiations and the ability of the parties to reach mutually-acceptable ROW renewal terms. These estimates could change depending on ROW negotiations.

Historically, NMGC’s ROW costs have been approved by the New Mexico Public Regulation Commission (“NMPRC”) for recovery in base rates charged to customers after being included in a rate case. NMGC has agreed to freeze rates until December 31, 2017 as part of the stipulation filed in NMPRC Case No. 13-00231-UT that would take effect if the NMPRC approves the stipulation. NMGC will seek to recover lease and ROW costs in future base rates charged to customers after December 31, 2017.

Determined as of the last day of the most recently ended Fiscal Year of New Mexico Gas Company, Inc. (“NMGC) in accordance with Financial Accounting Standards Board Accounting Standards Codification Section 715-60 (without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code), NMGC has accumulated postretirement benefit obligations of approximately $23,850,431 as of December 31, 2013.

The Company is the obligor of all of the Existing NMGI Bank Term Loan listed below, and New Mexico Gas Company, Inc. (NMGC) is the obligor of all remaining Indebtedness (as defined in the attached Agreement) listed below. Outstanding balances are as of June 30, 2014. See footnotes for obligees, collateral and Indebtedness paid upon the Closing.

In addition to the Indebtedness listed above, the remaining balance of the Indebtedness of NMGC consists of capital leases and other miscellaneous obligations, none of which individually exceeds $5,000,000 or in the aggregate exceeds $10,000,000.

Capitalized terms used but not defined herein shall have the definition assigned to them in the attached Agreement.

Now Therefore, in compliance with the Note Purchase Agreement, and in consideration of, the execution and delivery of the Note Purchase Agreement and the purchase of the Notes by each of the Noteholders, each Guarantor hereby covenants and agrees with, and represents and warrants to each of the Noteholders as follows:

Each Guarantor hereby irrevocably, unconditionally and jointly and severally with the other Guarantors guarantees to each Noteholder, the due and punctual payment in full of (a) the principal of, Make-Whole Amount (if any), prepayment premium (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 Purchase Agreement or any other Finance Document executed in connection therewith (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 collectibility 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 Guarantor agrees to pay the same when due to the Noteholders 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 Purchase 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 Guarantor agrees that the Notes issued in connection with the Note Purchase Agreement may (but need not) make reference to this Guaranty Agreement.

Each Guarantor agrees to pay and to indemnify and save each Noteholder harmless from and against any damage, loss, cost or expense (including the reasonable fees and disbursements of any law firm or external counsel) which such Noteholder 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 Guaranty Agreement, the Notes, the Note Purchase Agreement or any other Finance Document, 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 Guaranty Agreement, the Notes, the Note Purchase Agreement or any other Finance Document and (z) enforcing or defending (or determining whether or how to enforce or defend) the provisions of this Guaranty Agreement.

Each 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 Purchase Agreement.

Notwithstanding the foregoing provisions or any other provision of this Guaranty Agreement, the Noteholders (on behalf of themselves and their successors and assigns)and each Guarantor hereby agree that if at any time the Guaranteed Obligations exceed the Maximum Guaranteed Amount determined as of such time with regard to such Guarantor, then this 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 Guarantor or any Noteholder and shall be deemed to have been automatically consented to by each Guarantor and each Noteholder.

The obligations of each Guarantor hereunder shall be primary, absolute, irrevocable and unconditional, irrespective of the validity or enforceability of the Notes, the Note Purchase Agreement or any other Finance Document, shall not be subject to any counterclaim, setoff, deduction or defense based upon any claim such Guarantor may have against the Company or any Noteholder 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 Purchase Agreement or any other Finance Document (it being agreed that the obligations of each Guarantor hereunder shall apply to the Notes, the Note Purchase Agreement or any such other Finance Document as so

amended, restated, supplemented or otherwise modified from time to time) 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 guarantee by, 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 Purchase Agreement or any other Finance Document; (c) any bankruptcy, insolvency, arrangement, reorganization, readjustment, composition, liquidation or similar proceeding with respect to the Company or the Company’s property; (d) any merger, amalgamation or consolidation of any 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 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 Guarantor; or (f) 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 Guarantor or to any subrogation, contribution or reimbursement rights any Guarantor may otherwise have. Each 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.

Each 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 Purchase Agreement or any other Finance Document, 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 Noteholder against such Guarantor, including, without limitation, presentment to or demand for payment from the Company or any Guarantor with respect to any Note, notice to the Company or to any 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 Noteholder to enforce, assert or exercise any right, power or remedy including, without limitation, any right, power or remedy conferred in the Note Purchase Agreement, the Notes or any other Finance Document, (d) any requirement for diligence on the part of any Noteholder 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. The waivers of the Guarantors set forth in this Section 3 shall be continuing and irrevocable in nature and shall apply with respect to all Guaranteed Obligations, whether now existing or hereafter arising.

Each Guarantor authorizes the Noteholders, 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, or any obligations under the Note Purchase Agreement or any other Finance Document; (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 Purchase Agreement or any other Finance Document, including, without limitation, decreases or increases in amounts of principal, rates of interest, the Make-Whole Amount, prepayment premium or any other obligation; (c) to take and hold security for the payment of the Notes or amounts payable under the Note Purchase Agreement or any other Finance Document in accordance with Section 10.4(u) of the Note Purchase Agreement (or as may be otherwise be granted or pledged by the Company, any such Guarantor or any other obligor in respect of the Notes from time to time, as applicable), for the performance of this 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 Noteholders 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 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 Noteholders 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 Noteholders.

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 Noteholder 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 Guarantor or any other guarantors of a case or proceeding under a bankruptcy or insolvency law, such Guarantor agrees that, for purposes of this 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 Noteholder thereof had accelerated the same in accordance with the terms of the Note Purchase Agreement, and such Guarantor shall forthwith pay such accelerated Guaranteed Obligations.

(a)Each Guarantor will not exercise any rights which it may have acquired by way of subrogation under this 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 Guaranty Agreement unless and until all of the Guaranteed Obligations shall have been indefeasibly paid in full in cash.

(b)Each 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 Noteholders and the proceeds thereof shall be paid over to the Noteholders 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 Guarantor under this Guaranty Agreement.

(c)If any amount or other payment is made to or accepted by any 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 Noteholders and shall be paid over to the Noteholders 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 Guaranty Agreement.

(d)Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Note Purchase Agreement and that its agreements set forth in this Guaranty Agreement (including this Section 5) are knowingly made in contemplation of such benefits.

(e)Each Guarantor hereby agrees that, to the extent that a Guarantor shall have paid an amount hereunder to any Noteholder 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 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 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 Guarantor to the Noteholders of the Notes hereunder or under the Notes, the Note Purchase Agreement or any other Finance Document, and each Guarantor shall remain jointly and severally liable for the full payment and performance of the Guaranteed Obligations.

This 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 Noteholder on account of the Guaranteed Obligations is rescinded or must otherwise be restored or returned by a Noteholder 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.

Each Guarantor will ensure that its payment obligations under this 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.

Each Guarantor hereby covenants and agrees that, so long as any part of the Guaranteed Obligations shall remain outstanding, such Guarantor will perform and observe, and cause each of its Subsidiaries to perform and observe, all of the terms, covenants and agreements set forth in the Note Purchase Agreement on its or their part to be performed or observed or that the Company has agreed to cause such Guarantor or such Subsidiaries to perform or observe.

(a)Such Guarantor is a [corporation]/[limited liability company] duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign [corporation]/[limited liability company] and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Such Guarantor has the organizational power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, and to execute, deliver, and perform its obligations under this Guaranty Agreement.

(b)This Guaranty Agreement has been duly authorized by all necessary [corporate]/[limited liability company] action on the part of such Guarantor, and this Guaranty Agreement constitutes a legal, valid and binding obligation of such Guarantor, enforceable against it in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other

similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(c)The execution, delivery and performance by such Guarantor of this Guaranty Agreement and the consummation of the transactions contemplated herein will not (i) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of such Guarantor under, any indenture, mortgage, deed of trust, loan agreement, purchase or credit agreement, lease, organizational documents, or any other agreement or instrument to which such Guarantor is bound or by which such Guarantor or any of its respective properties may be bound or affected (other than such breach or default as may have been waived or otherwise approved pursuant to such indenture, mortgage, deed of trust, loan agreement, purchase or credit agreement, lease, organizational documents, or any other agreement or instrument), (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to such Guarantor or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to such Guarantor.

(d)No consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority is required in connection with the execution, delivery or performance by, or enforcement against, such Guarantor of this Guaranty Agreement other than (i) the approval of the NMPRC, [which has been obtained prior to the date hereof], and (ii) any post-closing notice filings required pursuant to the NMPRC approval.

(e)Upon the execution and delivery hereof, such Guarantor will be solvent, will be able to pay its debts as they mature, and will have capital sufficient to carry on its business.

This Guaranty Agreement and all guarantees, covenants and agreements of the Guarantors contained herein shall continue in full force and effect and shall not be discharged until such time as all of the Guaranteed Obligations and all other obligations hereunder shall be indefeasibly paid in full in cash and shall be subject to reinstatement pursuant to Section 6; provided, however, if (i) all of the Capital Stock of a Guarantor is sold, exchanged or otherwise transferred (be merger or otherwise) after which such Guarantor is no longer a Subsdiary or a Permitted Joint Venture, (ii) all of the assets of a Guarantor are sold, exchanged, transferred or otherwise disposed of pursuant to a transaction expressly permitted by the Note Purchase Agreement (but only if such Guarantor will not be a borrower or guarantor of obligations outstanding under any Principal Credit Facility after giving effect to such transaction), or (iii) the Required Holders execute and deliver a consent to the Company with respect to a Guarantor (subject to the provisions of Section 17.2(c) of the Note Purchase Agreement), then such Guarantor shall be released from its obligations under this Guaranty Agreement without further action.

All representations and warranties contained herein shall survive the execution and delivery of this Guaranty Agreement and may be relied upon by any subsequent Noteholder, regardless of any investigation made at any time by or on behalf of any Noteholder. All statements contained in any certificate or other instrument delivered by or on behalf of a Guarantor pursuant to this Guaranty Agreement shall be deemed representations and warranties of such Guarantor under this Guaranty Agreement. Subject to the preceding sentence, this Guaranty Agreement embodies the entire agreement and understanding between each Noteholder and the Guarantors and supersedes all prior agreements and understandings relating to the subject matter hereof.

Section 12.1.Requirements. Except as otherwise provided in the fourth paragraph of Section 1 of this Guaranty Agreement, this Guaranty Agreement may be amended, and the observance of any term hereof may be waived (either retroactively or prospectively), with (and only with) the written consent of each Guarantor and the Required Holders, except that no amendment or waiver (a) of any of the first three paragraphs of Section 1 or any of the provisions of Section 2, 3, 4, 5, 6, 7, 10 or 12 hereof, or any defined term (as it is used therein), or (b) which results in the limitation of the liability of any Guarantor hereunder (except to the extent provided in the fourth paragraph of Section 1 of this Guaranty Agreement) will be effective as to any Noteholder unless consented to by such Noteholder in writing.

(a)Solicitation. Each Guarantor will provide each Noteholder (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such Noteholder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof. Each Guarantor will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 12.2 to each Noteholder promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite Noteholders.

(b)Payment. The Guarantors will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any Noteholder as consideration for or as an inducement to the entering into by any Noteholder of any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each Noteholder even if such Noteholder did not consent to such waiver or amendment.

Section 12.3.Binding Effect. Any amendment or waiver consented to as provided in this Section 12 applies equally to all Noteholders and is binding upon them and upon each future Noteholder and upon each 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 Guarantor and the Noteholder nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any Noteholder. As used herein, the term “this Guaranty Agreement” and references thereto shall mean this Guaranty Agreement as it may be amended, restated, supplemented or otherwise modified from time to time.

Section 12.4.Notes Held By The Company, Etc. Solely for the purpose of determining whether the Noteholders 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 Guaranty Agreement, or have directed the taking of any action provided herein to be taken upon the direction of the Noteholders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by any Guarantor, the Company or any of their respective Affiliates shall be deemed not to be outstanding.

(a)if to any Guarantor, to such address as such Guarantor shall have specified to the Noteholders in writing, or

(b)if to any Noteholder, to such Noteholder at the addresses specified for such communications set forth in Schedule A to the Note Purchase Agreement, or such other address as such Noteholder shall have specified to the Guarantors in writing.

Section 14.1.Successors and Assigns; Joinder. All covenants and other agreements contained in this Guaranty Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns whether so expressed or not. It is agreed and understood that any Person may become a Guarantor hereunder by executing a Joinder Agreement substantially in the form of Exhibit A attached hereto and delivering the same to the Noteholders. Any such Person shall thereafter be a “Guarantor” for all purposes under this Guaranty Agreement.

Section 14.2.Severability. Any provision of this 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 14.3.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 Guaranty Agreement are for convenience of reference only and shall neither be deemed to be a part of this 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 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 14.4.Further Assurances. Each Guarantor agrees to execute and deliver all such documents, instruments and agreements 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 Guaranty Agreement.

Section 14.5.Governing Law. This 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.

(a)Each Guarantor irrevocably submits to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action or proceeding arising out of or relating to this Guaranty Agreement. To the fullest extent permitted by applicable law, each Guarantor 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)Each Guarantor consents to process being served by or on behalf of any Noteholder in any suit, action or proceeding of the nature referred to in Section 14.6(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 13 or at such other address of which such Noteholder shall then have been notified pursuant to such Section. Each Guarantor 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 14.6 shall affect the right of any Noteholder to serve process in any manner permitted by law, or limit any right that the Noteholders may have to bring proceedings against any Guarantor 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 GUARANTORS AND THE NOTEHOLDERS HEREBY WAIVE TRIAL BY JURY IN ANY ACTION BROUGHT ON OR WITH RESPECT TO THIS GUARANTY AGREEMENT OR OTHER DOCUMENT EXECUTED IN CONNECTION HEREWITH.

Section 14.7.CONDITION OF THE COMPANY. Each Guarantor acknowledges and agrees that it has the sole responsibility for, and has adequate means of, obtaining from the Company and any other guarantor of the Notes such information concerning the financial condition, business and operations of the Company and any such other guarantor as such Guarantor may require, and that the Noteholders have no duty, and such Guarantor is not relying on the Noteholders at any time, to disclose to such Guarantor any information relating to the business, operations or financial condition of the Company or any other guarantor (such Guarantor hereby waiving any duty on the part of the Noteholders to disclose such information and any defense relating to the failure to provide the same).

Section 14.8.Reproduction of Documents; Execution. This Guaranty Agreement may be reproduced by any Noteholder by any photographic, photostatic, electronic, digital, or other similar process and such Noteholder may destroy any original document so reproduced. Each Guarantor agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Noteholder in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 14.8 shall not prohibit any Guarantor or any other Noteholder from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction. A facsimile or electronic transmission of the signature page of a Guarantor shall be as effective as delivery of a manually executed counterpart hereof and shall be admissible into evidence for all purposes.
