Item 1.01 Entry into a Material Definitive Agreement.

Closing of Series 2022A Bonds

On May 12, 2022, PNM Resources, Inc.’s indirect wholly-owned subsidiary, Texas-New Mexico Power Company (“TNMP”), issued $65,000,000 aggregate principal amount of its 4.13% First Mortgage Bonds, due May 12, 2052, Series 2022A (the “Series 2022A Bonds”) in a private placement in reliance on an exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”). The Series 2022A Bonds were sold by TNMP to institutional accredited investors (as defined by Rule 501(a) of the Securities Act) pursuant to a Bond Purchase Agreement dated April 27, 2022 (the “Series 2022 Bond Purchase Agreement”). The Series 2022 Bond Purchase Agreement was filed as Exhibit 10.9 to TNMP’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on April 28, 2022.

The Series 2022A Bonds were issued pursuant to TNMP’s First Mortgage Indenture dated as of March 23, 2009 (the “First Mortgage Indenture”), between TNMP and U.S. Bank Trust Company, National Association (ultimate successor as trustee to The Bank of New York Mellon Trust Company, N.A.), as trustee (the “Trustee”), as previously supplemented and amended and as further supplemented by the Fifteenth Supplemental Indenture thereto, dated as of May 12, 2022, between TNMP and the Trustee (the “Fifteenth Supplemental Indenture” and, together with the First Mortgage Indenture, the “Series 2022A Indenture”). The Series 2022A Bonds are secured by a first mortgage lien on substantially all of TNMP’s property, subject to excepted encumbrances, reservations, contracts and other exceptions as are permitted by the Series 2022A Indenture, and rank equally in right of payment with all other securities theretofore or thereafter issued under the First Mortgage Indenture.

Interest on the Series 2022A Bonds is payable semiannually on May 12 and November 12 of each year, commencing on November 12, 2022, at a fixed rate of 4.13% per annum. TNMP may, upon not less than ten nor more than sixty days’ prior written notice (unless the holders of more than 50% of the principal amount of the then-outstanding Series 2022A Bonds of the applicable series agree in writing to another time period), prepay at any time all, or from time to time any part of, the Series 2022A Bonds of any series, in an amount not less than ten percent of the aggregate principal amount of the Series 2022A Bonds of such series then outstanding in the case of a partial prepayment, at a prepayment price equal to the sum of (a) 100% of the principal amount so prepaid, (b) accrued and unpaid interest thereon and (c) a make-whole amount, if any, determined for the prepayment date with respect to such principal amount. The principal amount of the Series 2022A Bonds is payable on May 12, 2052.

The Series 2022A Indenture contains events of default customary for such a transaction, including, without limitation: failure to pay interest on any Security (as defined in the Series 2022A Indenture) for sixty days after becoming due; failure to pay the principal of or premium on any Security when due; failure to comply with or breach of any covenant or warranty contained in the Series 2022A Indenture, subject to a ninety day cure period after written notice of default has been delivered; and certain events relating to reorganization, bankruptcy and insolvency of TNMP. If an “Event of Default” (as defined in the Series 2022A Indenture) occurs and is continuing, the Trustee or the holders of not less than thirty-three percent in principal amount of the Securities then outstanding may declare the principal amount of all Securities then outstanding to be immediately due and payable.

In addition, the Fifteenth Supplemental Indenture contains bond repurchase events (subject to a fifteen day cure period), including, without limitation: actions by TNMP or any Controlled Entity (as defined in the Fifteenth Supplemental Indenture) which subject a Series 2022A Bond holder to terrorism sanctions regulations; the sale or lease of TNMP’s assets in excess of specified thresholds during any calendar year; defaults in respect to obligations relating to certain debt; failure to deliver to each institutional investor Series 2022A Bond holder certain financial and business information related to TNMP; failure to maintain a ratio of consolidated indebtedness to consolidated capitalization of less than or equal to 0.65 to 1.0; and material misrepresentations of any representation or warranty contained in the Fifteenth Supplemental Indenture. If a “Bond Repurchase Event” (as defined in the Fifteenth Supplemental Indenture) occurs and is continuing, TNMP must repurchase the Series 2022A Bonds for a purchase price equal to the aggregate principal amount of the Series 2022A Bonds then outstanding, plus all accrued and unpaid interest thereon and a make-whole amount determined for the Bond Repurchase Event date with respect to such principal amount.

The Fifteenth Supplemental Indenture further includes a provision whereby a change in control in TNMP or PNM Resources Inc. (other than the pending merger between Avangrid, Inc. and PNM Resources, Inc.) would obligate TNMP to offer to prepay all of the Series 2022A Bonds at one-hundred percent (100%) of the principal amount of the Series 2022A Bonds, plus all accrued and unpaid interest thereon, but without any make-whole amount or other premium.





The above description of the Series 2022A Indenture does not purport to be a complete statement of the parties’ rights and obligations thereunder. Such description is qualified in its entirety by reference to the Fifteenth Supplemental Indenture, a copy of which is attached to this Current Report on Form 8-K as Exhibit 4.1, and the First Mortgage Indenture, as previously amended and supplemented, and as previously filed, each of which is incorporated herein by reference. The form of Series 2022A Bonds, which is included as a part of the Fifteenth Supplemental Indenture, is incorporated herein by reference.

Increase Supplement, Sixteenth Supplemental Indenture, and Series 2022B Bonds

On March 11, 2022, TNMP entered into a $75.0 million secured fourth amended and restated credit agreement among TNMP, the lenders party thereto, and KeyBank National Association (“KeyBank”), as administrative agent (the “TNMP 2022 Revolving Credit Agreement”). The TNMP 2022 Revolving Credit Agreement was filed as Exhibit 10.1 to the Current Report on Form 8-K filed on March 11, 2022. The TNMP 2022 Revolving Credit Agreement contains an accordion feature which would allow TNMP to increase the size of the credit facility from $75.0 million to up to $100.0 million, subject to certain conditions including adding one or more existing or new lenders to assume the additional amount and having additional first mortgage bonds of TNMP issued to secure the full increased credit facility.

Borrowings under the TNMP 2022 Revolving Credit Agreement were secured by $75.0 million aggregate principal amount of a series of first mortgage bonds of TNMP (the “Series 2009C Bonds”) issued on April 30, 2009, pursuant to the First Mortgage Indenture, as supplemented by the Third Supplemental Indenture, dated as of April 30, 2009, between TNMP and the Trustee (the “Third Supplemental Indenture”), as amended by a First Amendment, dated as of December 16, 2010, between TNMP and the Trustee (the “Amendment”). The First Mortgage Indenture was filed as Exhibit 4.1 to the Current Report on Form 8-K filed on March 27, 2009, the Third Supplemental Indenture was filed as Exhibit 4.1 to the Current Report on Form 8-K filed on May 6, 2009, and the Amendment was filed as Exhibit 4.1 to the Current Report on Form 8-K filed on December 17, 2010.

On May 13, 2022, TNMP exercised the accordion feature by entering into an increase supplement (the “Increase Supplement”) to the TNMP 2022 Revolving Credit Agreement (as supplemented, the “Credit Agreement”). The Credit Agreement now provides TNMP with a revolving credit facility for up to $100.0 million.

The above descriptions of the TNMP 2022 Revolving Credit Agreement and the Increase Supplement do not purport to be a complete statement of the parties’ rights and obligations thereunder. Such descriptions are qualified in their entirety by reference to the TNMP 2022 Revolving Credit Agreement, filed as Exhibit 10.1 to the Form 8-K filed on March 11, 2022, and the Increase Supplement, a copy of which is attached to this Current Report on Form 8-K as Exhibit 10.1, each of which is incorporated herein by reference.

In connection with the Increase Supplement, on May 13, 2022, TNMP issued $100,000,000 aggregate principal amount of its First Mortgage Bonds, Series 2022B (the “Series 2022B Bonds”) in exchange for the Series 2009C Bonds pursuant to the First Mortgage Indenture, as previously supplemented and amended and as further supplemented by the Sixteenth Supplemental Indenture thereto, dated as of May 13, 2022, between TNMP and the Trustee (the “Sixteenth Supplemental Indenture” and, together with the First Mortgage Indenture, the “Series 2022B Indenture”). Borrowings under the Credit Agreement are now secured by the Series 2022B Bonds and, in connection therewith on May 13, 2022, the Trustee cancelled the Series 2009C Bonds.

The above description of the Series 2022B Indenture does not purport to be a complete statement of the parties’ rights and obligations thereunder. Such description is qualified in its entirety by reference to the Sixteenth Supplemental Indenture, a copy of which is attached to this Current Report on Form 8-K as Exhibit 4.3, and the First Mortgage Indenture, as previously amended and supplemented, and as previously filed, each of which is incorporated herein by reference. The form of Series 2022B Bonds, which is included as a part of the Sixteenth Supplemental Indenture, is incorporated herein by reference.

The Series 2022A Bonds and the Series 2022B Bonds are not registered under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements and applicable state laws. This Current Report on Form 8-K does not constitute an offer to sell nor a solicitation of an offer to purchase the Series 2022A Bonds or the Series 2022B Bonds or any other securities, and shall not constitute an offer, solicitation or sale in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful.

The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the 2022 Bonds, in an amount not less than ten percent (10%) of the aggregate principal amount of the 2022 Bonds to be prepaid then outstanding in the case of a partial prepayment, at one-hundred percent (100%) of the principal amount so prepaid, together with accrued and unpaid interest thereon, and the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each Holder of the 2022 Bonds written notice, with a copy to the Trustee, of each optional prepayment under this Section 2.03 not less than ten (10) days and not more than sixty (60) days prior to the date fixed for such prepayment unless the Company and the Holders of more than fifty percent (50%) of the principal amount of the 2022 Bonds then outstanding agree in writing to another time period.

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 2022 Bond paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no 2022 Bond shall be issued in lieu of any prepaid principal amount of any 2022 Bond.
Section 2.04    Purchase of Bonds. The Company will not and will not permit any Subsidiary of the Company to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding 2022 Bonds except (a) upon the payment or prepayment of the 2022 Bonds in accordance with this Fifteenth Supplemental Indenture and the 2022 Bonds or (b) pursuant to an offer to purchase made by the Company or a Subsidiary of the Company pro rata to the Holders of all 2022 Bonds 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 ten (10) Business Days. If the Holders of more than fifty percent (50%) of the principal amount of the 2022 Bonds then outstanding accept such offer, the Company shall promptly notify the remaining Holders of 2022 Bonds of such fact and the expiration date for the acceptance by Holders of 2022 Bonds of such offer shall be extended by the number of days necessary to give each such remaining Holder at least five (5) Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all 2022 Bonds acquired by it or any Subsidiary of the Company pursuant to any payment, prepayment or purchase of 2022 Bonds pursuant to this Fifteenth Supplemental Indenture and no 2022 Bonds may be issued in substitution or exchange for any such 2022 Bonds.
Section 2.05    Make-Whole Amount.

Discounted Value means, with respect to the Called Principal of any 2022 Bond, 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 2022 Bonds is payable) equal to the Reinvestment Yield with respect to such Called Principal.
Reinvestment Yield means, with respect to the Called Principal of any 2022 Bond, 0.50% over the yield to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the 2022 Bond.
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 2022 Bond, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to 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 2022 Bond.
Remaining Average Life means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between
-13-


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 2022 Bond, 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 2022 Bonds, 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 2.03 or Section 2.07 or is declared to be due and payable pursuant to Section 10.02 of the Original Indenture.
Settlement Date means, with respect to the Called Principal of any 2022 Bond, the date on which such Called Principal is to be prepaid pursuant to Section 2.03 or Section 2.07 or is declared to be due and payable pursuant to Section 10.02 of the Original Indenture.

To the extent permitted by, and as provided in, the Indenture, modifications or alterations of the Indenture, or of any indenture supplemental thereto, and of the rights and obligations of the Company and of the Holders of the First Mortgage Bonds may be made, in certain cases without the consent of the Holders of the First Mortgage Bonds, as set forth in Section 14.01 of the Indenture, and otherwise with the consent of the Company by an affirmative vote of not less than a majority in amount of the First Mortgage Bonds entitled to vote then outstanding, at a meeting of Holders of the First Mortgage Bonds called and held as provided in the Indenture, or by an affirmative vote of not less than a majority in amount of the First Mortgage Bonds of any series entitled to vote then outstanding and affected by such modifications or alterations, in case one or more but less than all of the series of First Mortgage Bonds then outstanding under the Indenture are so affected; provided, however, that no such modifications or alterations shall be made which will affect the terms of payment of the principal of, or interest on, this Security, which are unconditional. The First Mortgage Bonds may be issued in series, for various principal sums, may mature at different times, may bear interest at different rates and may otherwise vary as provided in the Indenture. This Security is one of a series designated as “4.13% First Mortgage Bonds, due May 12, 2052, Series 2022A” of the Company, issued under and secured by the Indenture and all indentures supplemental thereto and described in an indenture supplemental thereto (herein called the “Fifteenth Supplemental Indenture”), dated as of May 12, 2022, executed by the Company to the Trustee.
The Company, at its option, may redeem all, or from time to time, any part of the First Mortgage Bonds of this series on not less than ten (10) days’ nor more than sixty (60) days’ notice by first-class mail, postage prepaid as provided in the Indenture at a Redemption Price equal to the sum of the principal amount so prepaid plus the Make-Whole Amount as defined in the Fifteenth Supplemental Indenture and upon the other terms and conditions therein and in the Indenture provided.

The Indenture contains provisions for satisfaction and discharge of the entire indebtedness of the First Mortgage Bonds of this series.
In case an Event of Default shall occur, the principal of all the First Mortgage Bonds at any such time Outstanding under the Indenture may be declared or may become due and payable, upon the conditions and in the manner and with the effect provided in the Indenture. The Indenture provides that such declaration may in certain events be waived by the Holders of a majority in principal amount of the First Mortgage Bonds outstanding. In the event of any declaration of acceleration of the maturity of the First Mortgage Bonds, the amount due and payable on this Security (and for all outstanding First Mortgage Bonds of this series) shall consist of the unpaid principal and accrued and unpaid interest thereon plus the Make-Whole Amount (as defined in Section 2.05 of the Fifteenth Supplemental Indenture), which Make-Whole Amount shall be determined as of the date of such declaration.
No recourse shall be had for the payment of the principal of, or Make-Whole Amount, if any, or the interest on, this Security, or for any claim based hereon or on the Indenture or any indenture supplemental thereto, against any incorporator, or against any stockholder, director or officer, past, present or future, of the Company, as such, or of any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation, whether for amounts unpaid on stock subscriptions or by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability, whether at common law, in equity, by any constitution, statute or otherwise, of incorporators, stockholders, directors or officers being released by every owner hereof by the acceptance of this First Mortgage Bond and as part of the consideration for the issue hereof, and being likewise released by the terms of the Indenture.
This Security is transferable by the registered owner hereof, in person or by duly authorized attorney, on the books of the Company to be kept for that purpose as provided for in the Indenture upon surrender and cancellation of this Security and on presentation of a duly executed written instrument of transfer, and thereupon a new Security of the same series of First Mortgage Bonds, of the same aggregate principal amount and in authorized denominations will be issued to the transferee or transferees in exchange therefor; and this Security, with or without others of like series, may in like manner be exchanged for one or more new First Mortgage Bonds of the same series of other authorized denominations but of the same aggregate principal amount; all upon payment of the charges and subject to the terms and conditions set forth in the Indenture.
This Security shall be subject to certain restrictions on transfer as set forth in the Indenture and the Fifteenth Supplemental Indenture.



This Security shall be governed by, and construed in accordance with, the laws of the State of New York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act would be applicable were the Fifteenth Supplemental Indenture qualified under the Trust Indenture Act and except to the extent that the law of any other jurisdiction shall mandatorily govern the creation, perfection, priority or enforcement of the Lien of the Indenture, as supplemented and amended by all indentures supplemental thereto (including the Fifteenth Supplemental Indenture), or the exercise of remedies with respect to the Mortgaged Property.

-4-


authenticated and delivered in accordance with the provisions of, and, except as hereinafter provided, shall in all respects be subject to all of the terms, conditions and covenants of the Indenture as supplemented by this Sixteenth Supplemental Indenture. For purposes of the Indenture, the Collateral Bonds shall constitute a single series of Securities and may be issued in an unlimited aggregate principal amount (subject to the limitations set forth in Article IV of the Indenture), although the initial issuance, authentication and delivery of the Collateral Bonds shall be in the aggregate principal amount of $100,000,000.

Section 2.02 Form and Terms of the Collateral Bonds.

(a) The form and terms of the Collateral Bonds pursuant to the authority granted by this Sixteenth Supplemental Indenture in accordance with Sections 2.01 and 3.01 of the Original Indenture are set forth herein. The Collateral Bonds shall be issued in registered form without coupons in the denominations of $1,000 and integral multiples of $1,000, appropriately numbered and substantially in the form set forth as Exhibit A hereto. The Collateral Bonds are to be issued to and registered in the name of the Administrative Agent under the Credit Agreement, and are issued as collateral security for any and all Borrower Obligations.

(b) The Collateral Bonds shall mature on the Maturity Date and shall bear interest at the Interest Rate, payable on each Interest Payment Date. The Collateral Bonds shall be payable as to principal and interest in any coin or currency of the United States of America which at the time of payment is legal tender for public and private debts and as otherwise provided for in the Indenture.

(c) The obligation of the Company to pay the principal of and accrued interest on the Collateral Bonds at or after the Maturity (x) shall be deemed to have been satisfied and discharged in full in the event that all amounts then due in respect of the Borrower Obligations shall have been paid in full in immediately available funds or (y) shall be deemed to remain unsatisfied in an amount equal to the aggregate amount then due in respect of the Borrower Obligations and remaining unpaid (not in excess, however, of the amount otherwise then due in respect of principal of and accrued interest on the Collateral Bonds). The aggregate principal amount of the Collateral Bonds shall be reduced in amount pursuant to Section 2.03 herein.

(d) The obligation of the Company to pay the accrued interest on the Collateral Bonds on any Interest Payment Date prior to the Maturity (a) shall be deemed to have been satisfied and discharged in full in the event that all amounts then due in respect of the Borrower Obligations shall have been paid in full in immediately available funds or (b) shall be deemed to remain unsatisfied in an amount equal to the aggregate amount then due in respect of the Borrower Obligations and remaining unpaid (not in excess, however, of the amount otherwise then due in respect of interest on the Collateral Bonds).

Section 2.03 Redemption; Repurchase. (a) The Collateral Bonds are not redeemable at the option of the Company.

(c) On a Credit Repurchase Date, the Company shall repurchase (the “Credit Repurchase Requirement”) the Collateral Bonds (including all accrued and unpaid interest on the Collateral Bonds) for a purchase price equal to the Borrower Obligations (the “Credit Repurchase Amount”). On the Credit Repurchase Date, the Company will deposit with the Trustee immediately available funds in an amount equal to the Credit Repurchase Amount and the Trustee shall pay such amount as soon as practicable after receipt thereof to the Administrative Agent.

(d) The Company’s obligation to satisfy a Credit Repurchase Requirement shall be mandatory upon the occurrence of a Credit Repurchase Event. Upon a Credit Acceleration Event, the Administrative Agent may, at its option, deliver a Credit Written Demand upon the Company’s receipt of which the Company’s compliance with the Credit Repurchase Requirement shall be mandatory.

(e) Following a Credit Repurchase Event, the Administrative Agent shall promptly deliver to the Company a Credit Notice.

(f) Any Collateral Bonds surrendered to the Trustee in connection with a Credit Repurchase Requirement or in connection with a reduction in the Revolving Committed Amount shall promptly be cancelled in accordance with Section 3.09 of the Indenture.

-6-


without service charge, a new Collateral Bond of any authorized denomination as requested by such Holder and of like tenor and in aggregate principal amount equal to and in exchange for the portion of the principal of the Collateral Bond so surrendered that is not being repurchased or reduced.

Section 2.04 [Reserved].

Section 2.05 Restrictions on Transfer. The Collateral Bonds shall be issued to and registered in the name of the Administrative Agent and shall not be transferable by the Administrative Agent, except to (i) a successor Administrative Agent appointed pursuant to the terms of Section 10.06 of the Credit Agreement or (ii) the Company.

Section 2.06 Sinking Fund. The Collateral Bonds are not subject to any sinking fund.

Section 2.07 Surrender. The Administrative Agent shall surrender the Collateral Bonds to the Trustee when all of the Borrower Obligations shall have been duly paid in full in immediately available funds, and the Credit Agreement (including, without limitation, all Commitments thereunder) shall have been terminated, and the Trustee shall cancel such Collateral Bonds upon receipt thereof.

[FORM OF REVERSE OF FIRST MORTGAGE BOND, SERIES 2022B]

This Security is one of a duly authorized issue of First Mortgage Bonds of the Company (herein called the “First Mortgage Bonds”), unlimited in aggregate principal amount, of the series hereinafter specified, all issued and to be issued under and equally secured by an indenture, dated as of March 23, 2009, executed by the Company and delivered to U.S. Bank Trust Company, National Association (ultimate successor as trustee to The Bank of New York Mellon Trust Company, N.A.), as Trustee (herein called the “Trustee”) (said indenture being herein called the “Indenture”), to which Indenture and all indentures supplemental thereto (including the Sixteenth Supplemental Indenture hereinafter referred to) reference is hereby made for a description of the properties mortgaged and pledged, the nature and extent of the security, the rights of the registered owners of the First Mortgage Bonds and of the Trustee in respect thereto, and the terms and conditions upon which the First Mortgage Bonds are, and are to be, secured, and for a statement of the respective rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the First Mortgage Bonds and of the terms upon which the First Mortgage Bonds are, and are to be, authenticated and delivered. To the extent permitted by, and as provided in, the Indenture, modifications or alterations of the Indenture, or of any indenture supplemental thereto, and of the rights and obligations of the Company and of the Holders of the First Mortgage Bonds may be made, in certain cases without the consent of the Holders, as set forth in Section 14.01 of the Indenture, and otherwise with the consent of the Company by an affirmative vote of not less than a majority in amount of the First Mortgage Bonds entitled to vote then outstanding, at a meeting of Holders called and held as provided in the Indenture, and by an affirmative vote of not less than a majority in amount of the First Mortgage Bonds of any series entitled to vote then outstanding and affected by such modifications or alterations, in case one or more but less than all of the series of First Mortgage Bonds then outstanding under the Indenture are so affected; provided, however, that no such modifications or alterations shall be made which will affect the terms of payment of the principal of, or interest on, this First Mortgage Bond, which are unconditional. The First Mortgage Bonds may be issued in series, for various principal sums, may mature at different times, may bear interest at different rates and may otherwise vary as provided in the Indenture. This First Mortgage Bond is one of a series designated as “First Mortgage Bonds, Series 2022B” (herein called the “Collateral Bonds”) of the Company, issued under and secured by the Indenture and described in an indenture supplemental thereto (herein called the “Sixteenth Supplemental Indenture”), dated as of May 13, 2022, executed by the Company and delivered to the Trustee.

The Collateral Bonds are to be issued and delivered to the Administrative Agent as collateral security for the Borrower Obligations.

The obligation of the Company to pay the principal of and accrued interest on the Collateral Bonds at or after the Maturity (x) shall be deemed to have been satisfied and discharged in full in the event that all amounts then due in respect of the Borrower Obligations shall have been paid in full in immediately available funds or (y) shall be deemed to remain unsatisfied in an amount equal to the aggregate amount then due in respect of the Borrower Obligations and remaining unpaid (not in excess, however, of the amount otherwise then due in respect of principal of and accrued interest on the Collateral Bonds). The aggregate principal
A-4


amount of the Collateral Bonds shall be reduced in amount pursuant to Section 2.03 of the Sixteenth Supplemental Indenture.

The obligation of the Company to pay the accrued interest on the Collateral Bonds on any Interest Payment Date prior to the Maturity (a) shall be deemed to have been satisfied and discharged in full in the event that all amounts then due in respect of the Borrower Obligations shall have been paid in full in immediately available funds or (b) shall be deemed to remain unsatisfied in an amount equal to the aggregate amount then due in respect of the Borrower Obligations and remaining unpaid (not in excess, however, of the amount otherwise then due in respect of interest on the Collateral Bonds).
The Trustee may at any time and all times conclusively presume that the obligation of the Company to pay the principal of and interest on the Collateral Bonds as the same shall have become due and payable, shall have been fully satisfied and discharged unless and until a Responsible Officer of the Trustee shall have received at the Corporate Trust Office a written notice from the Administrative Agent stating (A) that timely payment of principal and interest on the Collateral Bonds has not been made, (B) that the Company is in arrears as to the payments required to be made by it to the Administrative Agent pursuant to the Credit Agreement and (C) the amount of the arrearage. This paragraph is solely for the benefit of the Trustee.

This Collateral Bond is not redeemable at the option of the Company.

A reduction in the Revolving Committed Amount in accordance with Section 2.1(d) of the Credit Agreement shall automatically reduce the aggregate principal amount of the Collateral Bonds by the aggregate amount of such reduction in the Revolving Committed Amount, upon surrender by the Administrative Agent to the Trustee at the Corporate Trust Office of the Trustee of Collateral Bonds in an aggregate principal amount equal to the reduction, which surrender shall be a condition precedent to the reduction in the Revolving Committed Amount and a condition precedent to the reduction of the aggregate principal amount of the Collateral Bonds.

On a Credit Repurchase Date, the Company shall repurchase (the “Credit Repurchase Requirement”) the Collateral Bonds (including all accrued and unpaid interest on the Collateral Bonds) for a purchase price equal to the Borrower Obligations (the “Credit Repurchase Amount”). On the Credit Repurchase Date, the Company will deposit with the Trustee immediately available funds in an amount equal to the Credit Repurchase Amount and the Trustee shall pay such amount as soon as practicable after receipt thereof to the Administrative Agent.

Payment of a Credit Repurchase Amount equal to the Borrower Obligations as of the applicable Credit Repurchase Date shall be deemed to satisfy and discharge in full the principal of, and accrued and unpaid interest on, the Collateral Bonds.

The Company’s obligation to satisfy a Credit Repurchase Requirement shall be mandatory upon the occurrence of a Credit Repurchase Event. Upon a Credit Acceleration Event, the Administrative Agent may, at its option, deliver a Credit Written Demand, upon the
A-5


Company’s receipt of which the Company’s compliance with the Credit Repurchase Requirement shall be mandatory.

Any Collateral Bond which is to be repurchased only in part (or reduced in part, pursuant to a reduction in the Revolving Committed Amount) shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Collateral Bond, without service charge, a new Collateral Bond of any authorized denomination as requested by such Holder and of like tenor and in aggregate principal amount equal to and in exchange for the portion of the principal of the Collateral Bond so surrendered that is not being repurchased or reduced.
In case an Event of Default shall occur, the principal of all the Collateral Bonds at any such time outstanding under the Indenture may be declared or may become due and payable, upon the conditions and in the manner and with the effect provided in the Indenture. The Indenture provides that such declaration may in certain events be waived by the Holders of a majority in principal amount of the Collateral Bonds outstanding.

Except as set forth in Section 2.05 of the Sixteenth Supplemental Indenture, this Collateral Bond is not transferable by the Holder thereof.

No recourse shall be had for the payment of the principal of, or the interest on, this Collateral Bond, or for any claim based hereon or on the Indenture or any indenture supplemental thereto, against any incorporator, or against any stockholder, director or officer, past, present or future, of the Company, as such, or of any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation, whether for amounts unpaid on stock subscriptions or by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability, whether at common law, in equity, by any constitution, statute or otherwise, of incorporators, stockholders, directors or officers being released by every owner hereof by the acceptance of this Collateral Bond and as part of the consideration for the issue hereof, and being likewise released by the terms of the Indenture.

This Collateral Bond shall be governed by, and construed in accordance with, the laws of the State of New York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act would be applicable were the Sixteenth Supplemental Indenture qualified under the Trust Indenture Act and except to the extent that the law of any other jurisdiction shall mandatorily govern the creation, perfection, priority or enforcement of the Lien of the Indenture or the exercise of remedies with respect to the Mortgaged Property.

The Administrative Agent shall surrender this Collateral Bond to the Trustee when all of the Borrower Obligations shall have been duly paid in full in immediately available funds, and the Credit Agreement (including, without limitation, all Commitments thereunder) shall have been terminated, and the Trustee shall cancel such Collateral Bonds upon receipt thereof.
