Ladies and Gentlemen:

The Company will authorize the issue and sale of (i) $50,000,000 aggregate principal amount of its 2.29% Senior Unsecured Notes, Series A, due December 30, 2031 (the “Series A Notes”), and (ii) $100,000,000 aggregate principal amount of its 2.97% Senior Unsecured Notes, Series B, due December 30, 2041 (the “Series B Notes”; collectively with the Series A Notes, the “Notes”). The Notes shall be substantially in the forms set out in Schedule 1A and Schedule 1-B, as applicable. Certain capitalized and other terms used in this Agreement are defined in Schedule A and, for purposes of this Agreement, the rules of construction set forth in Section 22.4 shall govern. References to “Series” of Notes shall refer to the Series A Notes and the Series B Notes or all, as the context may require.

SECTION 2. SALE AND PURCHASE OF NOTES.

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 specified opposite such Purchaser’s name in the Purchaser Schedule 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.

(b) Neither the Company nor any Subsidiary is (i) in violation of any order, judgment, decree or ruling of any court, any arbitrator of any kind or any Governmental Authority or (ii) in violation of any applicable law, ordinance, rule or regulation of any Governmental Authority (including Environmental Laws, the USA PATRIOT Act or any of the other laws and regulations that are referred to in Section 5.16), which default or violation would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section 5.9. Taxes. The Company and its Subsidiaries have filed all tax returns that are required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments payable by them, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (i) the amount of which, individually or in the aggregate, is not Material

-6-

Public Service Company of New Mexico Note Purchase Agreement

or (ii) 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 U.S. federal, state or other taxes for all fiscal periods are adequate. The U.S. 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, 2017.

Section 5.10. Title to Property; Leases. 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 such 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 except for those defects in title and Liens that, individually or in the aggregate, would not have a Material Adverse Effect. All Material leases are valid and subsisting and are in full force and effect in all material respects.

Section 5.11. Licenses, Permits, Etc. Except as disclosed in the Disclosure Documents, 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, except for those conflicts that, individually or in the aggregate, would not have a Material Adverse Effect.

Section 5.12. Compliance with Employee Benefit Plans. (a) The Company and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Titles 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), and no event, transaction or condition relating to such employee benefit plans has occurred or exists that would, individually or in the aggregate, 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 Titles I or IV of ERISA or to section 430(k) of the Code or to any such penalty or excise tax provisions under the Code or federal law or section 4068 of ERISA or by the granting of a security interest in connection with the amendment of a Plan, other than such liabilities or Liens as would 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 last valuation date for which results have been certified 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 $70,000,000 in the case of any single Plan and by more than $70,000,000 in the aggregate for all Plans. The term “benefit liabilities”

-7-

Public Service Company of New Mexico Note Purchase Agreement

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 (and are not subject to contingent withdrawal liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material.

(d) The present value (determined using actuarial and other assumptions which are reasonable with respect to the benefits provided and the employees participating) of the liability of the Company and each ERISA Affiliate for post-retirement welfare benefits to be provided to their current and former employees under Plans which are welfare benefit plans (as defined in section 3(1) of ERISA), net of all assets under all such Plans allocable to such benefits, are reflected on the financial statements in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 715-60.

(e) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of section 406 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 to be used to pay the purchase price of the Notes to be purchased by such Purchaser.

(f) The Company and its Subsidiaries do not have any Non-U.S. Plans.

Section 5.13. Private Offering by the Company. 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 the Notes or any similar Securities from, or otherwise approached or negotiated in respect thereof with, any Person other than 5 Institutional Investors (including the Purchasers), each of which has been offered the Notes at a private sale for investment. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of section 5 of the Securities Act or to the registration requirements of any Securities or blue sky laws of any applicable jurisdiction.

Section 5.14. Use of Proceeds; Margin Regulations. The Company will apply the proceeds of the sale of the Notes hereunder for funding of capital expenditures, including funding for the purchase of the Western Spirit transmission line, refinancing existing short-term debt, and general corporate purposes. No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any Securities under such circumstances as to involve the Company in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 5% of the value of the consolidated assets of the Company and its Subsidiaries and the Company does not have any present intention that margin stock will constitute

-8-

Public Service Company of New Mexico Note Purchase Agreement

more than 5% of the value of such assets. As used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U.

Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

Section 8.5. Purchase of Notes.

The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment or prepayment of Notes pursuant to this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

Section 8.6. Make-Whole Amount.

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; provided further that the Make-Whole Amount shall equal zero with respect to the relevant Series of Notes if such prepayment occurs (i) on or after the date which is October 1, 2031 in the case of the Series A Notes and (ii) on or after the date which is July 3, 2041 in the case of the Series B Notes. 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.

-18-

Public Service Company of New Mexico Note Purchase Agreement

“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, the sum of (a) 0.50% plus (b) the yield to maturity implied by the “Ask Yield(s)” reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (i) converting U.S. Treasury xxxx quotations to bond equivalent yields in accordance with accepted financial practice and (ii) interpolating linearly between the “Ask Yields” Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Note, the sum of (x) 0.50% plus (y) the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year comprised of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

-19-

Public Service Company of New Mexico Note Purchase Agreement

“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 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.

Section 8.7. Change of Control.

(a) Notice of Change of Control.

SECTION 9. AFFIRMATIVE COVENANTS.

From the Execution Date until the Closing and thereafter, so long as any of the Notes are outstanding, the Company covenants that:

Section 9.1. Compliance with Laws. Without limiting Section 10.4, the Company will, and will cause each of its Subsidiaries to, comply with all laws, ordinances or governmental rules or regulations to which each of them is subject (including ERISA, Environmental Laws, the USA PATRIOT Act and the other laws and regulations that are 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, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

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

Section 9.3. Maintenance of Properties. The Company will, and will cause each of its Subsidiaries to, maintain and keep, or cause to be maintained and kept, their respective properties in good working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be properly conducted at all times, provided that this Section 9.3 shall not prevent the Company or any Subsidiary from discontinuing the operation and the 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 would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and provided, further, that this provision shall not apply to properties required to be closed, discontinued or abandoned pursuant to a law, legal order, mandate or requirement from the NMPRC or any other federal or

-21-

state governmental authority or regulatory authority with the authority to regulate or oversee any aspect of the business of the Company or its Affiliates.

Section 9.4. Payment of Taxes and Claims. The Company will, and will cause each of its Subsidiaries to, file all 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, levies or claims payable by any of them, to the extent the same have become due and payable and before they have become delinquent, provided that neither the Company nor any Subsidiary need pay any such tax, assessment, charge, 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 would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section 9.5. Corporate Existence, Etc. Subject to Section 10.2, the Company will at all times preserve and keep its existence in full force and effect. Subject to Sections 10.2 and 10.3, the Company will at all times preserve and keep in full force and effect the corporate existence of each of its Subsidiaries (unless dissolved or merged into the Company or a Wholly-Owned Subsidiary) and all Material rights and franchises of the Company and its Subsidiaries unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise would not, individually or in the aggregate, have a Material Adverse Effect.

Section 9.6. Books and Records. The Company will, and will cause each of its Subsidiaries to, maintain proper 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. The Company will, and will cause each of its Subsidiaries to, keep books, records and accounts which, in reasonable detail, accurately reflect all transactions and dispositions of assets. The Company and its Subsidiaries have devised a system of internal accounting controls sufficient to provide reasonable assurances that their respective books, records, and accounts accurately reflect all transactions and dispositions of assets and the Company will, and will cause each of its Subsidiaries to, continue to maintain such system.

Section 9.7. Guarantors. (a) The Company will (x) cause each of its Subsidiaries that guarantees or otherwise becomes liable at any time, whether as a borrower or an additional or co-borrower or otherwise, for or in respect of any Indebtedness under any Material Credit Facility (a “Subsidiary Guarantor”) and (y) use commercially reasonable efforts to cause any other entity that is not a Subsidiary that guarantees or otherwise becomes liable at any time, whether as a borrower or an additional or co-borrower or otherwise, for or in respect of any Indebtedness under a Material Credit Facility (a “Non-Subsidiary Guarantor”; together with any other Non-Subsidiary Guarantors and any Subsidiary Guarantors, each a “Guarantor”) to concurrently therewith (or, if prior to the Closing, at Closing):

(i) enter into an agreement in form and substance satisfactory to the Required Holders providing for the guaranty by such Guarantor, on a joint and several basis with all

-22-

other such Guarantors, of (x) the prompt payment in full when due of all amounts payable by the Company pursuant to the Notes (whether for principal, interest, Make-Whole Amount or otherwise) and this Agreement, including all indemnities, fees and expenses payable by the Company thereunder and (y) the prompt, full and faithful performance, observance and discharge by the Company of each and every covenant, agreement, undertaking and provision required pursuant to the Notes or this Agreement to be performed, observed or discharged by it (a “NPA Guaranty”); and

(A) an executed counterpart of such NPA Guaranty;

(B) a certificate signed by an authorized responsible officer of such Guarantor containing representations and warranties on behalf of such Guarantor to the same effect, mutatis mutandis, as those contained in Sections 5.1, 5.2, 5.6, 5.7 and 5.16 of this Agreement (but with respect to such Guarantor and such NPA Guaranty rather than the Company);

(C) all documents as may be reasonably requested by the Required Holders to evidence the due organization, continuing existence and, where applicable, good standing of such Guarantor and the due authorization by all requisite action on the part of such Guarantor of the execution and delivery of such NPA Guaranty and the performance by such Guarantor of its obligations thereunder; and

(D) an opinion of counsel reasonably satisfactory to the Required Holders covering such matters relating to such Guarantor and such NPA Guaranty as the Required Holders may reasonably request.

(b) At the election of the Company and by written notice to each holder of Notes, any Guarantor may be discharged from all of its obligations and liabilities under its NPA Guaranty and shall be automatically released from its obligations thereunder without the need for the execution or delivery of any other document by the holders, provided that (i) if such Guarantor is a guarantor or is otherwise liable for or in respect of any Material Credit Facility, then such Guarantor has been released and discharged (or will be released and discharged concurrently with the release of such Guarantor under its NPA Guaranty) under such Material Credit Facility, (ii) at the time of, and after giving effect to, such release and discharge, no Default or Event of Default shall be existing, (iii) no amount is then due and payable under such NPA Guaranty, (iv) if in connection with such Guarantor being released and discharged under any Material Credit Facility, any fee or other form of consideration is given to any holder of Indebtedness under such Material Credit Facility for such release, the holders of the Notes shall receive equivalent consideration substantially concurrently therewith and (v) each holder shall have received a certificate of a Responsible Officer certifying as to the matters set forth in clauses (i) through (iv).

(c) The failure of a Non-Subsidiary Guarantor to comply with Section 9.7(a)(i) or (ii) will constitute non-compliance by a Guarantor with this Section 9.7.

-23-

Section 9.8. Most Favored Lender. (a) If at any time after the date of this Agreement the Company amends or modifies any financial covenant or any event of default in the nature of a financial covenant (or the related definitions or provisions governing accounting terms) (each, a “Financial Covenant”) in any Material Credit Facility that is similar to any Financial Covenant now or hereafter included herein, or if a Financial Covenant is added to such Material Credit Facility (any such amended, modified or added Financial Covenant, a “Modified Covenant”), then the Company shall provide a Most Favored Lender Notice to each holder (or if prior to Closing, to the Purchasers) of the Notes, and such Financial Covenant herein shall be deemed to be amended, modified or added automatically without any further action on the part of the Company or any holder; provided that if such Modified Covenant is less restrictive on the Company, then the amendment, modification or addition to this Agreement shall take effect fifteen (15) days after receipt of such Most Favored Lender Notice, unless the Required Holders notify the Company of their objection to such amendment, modification or addition within such fifteen (15) day period, in which case such amendment, modification or addition to this Agreement will not take effect; provided further that, notwithstanding the foregoing, no such amendment, modification or addition shall increase the ratio contained in this Section 10.7 in excess of 0.65 to 1.00 (whether by amending the ratio, the related definitions or provisions governing accounting terms) without the consent of the Required Holders.

(b) Notwithstanding the foregoing, if a Default or an Event of Default then exists and the amendment, modification or addition of any Financial Covenant herein would make such provision less restrictive on the Company, then such Financial Covenant shall only be deemed automatically amended, modified or added at such time when such Default or Event of Default no longer exists, if such time should occur. Furthermore, if any fee or other consideration shall be given to the lenders under such Material Credit Facility in connection with a Modified Covenant, the equivalent of such fee or other consideration shall be given, pro rata, to the holders of the Notes; provided that no fee or other consideration shall be due if the Modified Covenant is made in connection with a renewal, restatement or extension of or entry into such Material Credit Facility.

(c) “Most Favored Lender Notice” means, in respect of any Modified Covenant, a written notice to each of the holders of the Notes delivered promptly, and in any event within twenty (20) Business Days after the inclusion of such Modified Covenant in any Material Credit Facility (including by way of amendment or other modification of any existing provision thereof) from a Responsible Officer referring to the provisions of this Section 9.8 and setting forth a reasonably detailed description of such Modified Covenant (including any defined terms used therein) and related explanatory calculations, as applicable.

Although it will not be a Default or an Event of Default if the Company fails to comply with any provision of Section 9 on or after the Execution Date and prior to the Closing, if the Company fails to comply with any provision of Section 9 on or after the Execution Date and prior to the Closing, then any of the Purchasers may elect not to purchase the Notes on the date of the Closing.

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 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.

Section 12.2. Other Remedies. If any Default or 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 or in any Note or NPA Guaranty, 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.

Section 12.3. Rescission. 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

-31-

Public Service Company of New Mexico Note Purchase Agreement

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.

Section 12.4. No Waivers or Election of Remedies, Expenses, Etc. 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, any NPA Guaranty or any Note 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 reasonable attorneys’ fees, expenses and disbursements.

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 this Section 20.

In the event that as a condition to receiving access to information relating to the Company or its Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Note is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual workspace or otherwise) which is different from this Section 20, this Section 20 shall not be amended thereby and, as between such Purchaser or such holder and the Company, this Section 20 shall supersede any such other confidentiality undertaking.

SECTION 21. SUBSTITUTION OF PURCHASER.

Each Purchaser shall have the right to substitute any one of its Affiliates or another Purchaser or any one of such other Purchaser’s Affiliates (a “Substitute Purchaser”) 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 Substitute Purchaser, shall contain such Substitute Purchaser’s agreement to be bound by this Agreement and shall contain a confirmation by such Substitute Purchaser of the accuracy with respect to it of the representations

In the event that such Substitute Purchaser is so substituted as a Purchaser hereunder and such Substitute Purchaser thereafter transfers to such original Purchaser all of the Notes then held by such Substitute Purchaser, upon receipt by the Company of notice of such transfer, any reference to such Substitute Purchaser as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Substitute Purchaser, 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.

SECTION 22. MISCELLANEOUS.
