Section 2.16. Private Offering. Neither the Company nor anyone acting on its behalf has offered any of the Bonds or any similar Security of the Company for sale to, or solicited offers to buy any thereof from, or otherwise approached or negotiated with respect thereto with, any prospective purchaser, other than the Purchasers and six (6) other Institutional Investors, each of whom was offered all or a portion of the Bonds at private sale for investment. The Company agrees that neither the Company nor anyone acting on its behalf will offer the Bonds or any part thereof or any similar Securities for issue or sale to, or solicit any offer to acquire any of the same from, anyone so as to bring the offering, issuance or sale of the Bonds within the registration provisions of Section 5 of the Securities Act.

(b) has not failed to obtain any material license, permit, franchise or other governmental authorization necessary to the ownership of its Property or to the conduct of its business;

which violation or failure to obtain might, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(a) is not a party to any contract or agreement ([other than the Indenture]) which restricts the right or ability of the Company to incur debt; or

(b) has not agreed or consented to cause or permit in the future (upon the happening of a contingency or otherwise) any of its Property, whether now owned or hereafter acquired, to be subject to a Lien not permitted by the Indenture.

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), and no event, transaction or condition has occurred or, to the knowledge of the Company, 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 401(a)(29) or 412 of the Code, other than such liabilities or Liens as would not be individually or in the aggregate Material.

(b): Neither the Company nor any ERISA Affiliate is a party to, participates in, maintains, contributes to, or has any liability or contingent liability with respect to an employee benefit plan, which is subject to Title IV of ERISA. The Company does not have any expected post-retirement benefit obligation (determined as of the last day of the Company's most recently ended fiscal year in accordance with Financial Accounting Standards Board Statement No. 106).

(c): The execution and delivery of this Agreement and the issuance and sale of the Bonds 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 in the first sentence of this Section 2.19(c) is made in reliance upon and subject to the accuracy of your representation in Section 1.3(b) as to the sources of the funds used to pay the purchase price of the Bonds to be purchased by you.

Section 2.20. Environmental Compliance. Except as set forth in Part III of Annex 3 hereto:

(a) Compliance—to the knowledge of the Company, the Company is in compliance with all Environmental Protection Laws in effect in each jurisdiction where it is presently doing business, except such failures so to comply that would not, in the aggregate, be reasonably expected to have a Material Adverse Effect;

(b) Liability—to the knowledge of the Company, the Company is not subject to any liability under any Environmental Protection Laws that, in the aggregate, could be reasonably expected to have a Material Adverse Effect; and

(i) written notice from any Governmental Authority by which any of its present or previously-owned or leased real Properties has been designated, listed, or identified in any manner by any Governmental Authority charged with administering or enforcing any Environmental Protection Law as a Hazardous Substance disposal or removal site, "Super Fund" clean-up site, or candidate for removal or closure pursuant to any Environmental Protection Law;

(ii) written notice of any Lien arising under or in connection with any Environmental Protection Law that has attached to any revenues of, or to any of its owned or leased real Properties; or

(iii) summons, citation, notice, directive, letter, or other communication, written or oral, from any Governmental Authority concerning any intentional or unintentional action or omission by the Company in connection with its ownership or leasing of any real Property resulting in the releasing, spilling, leaking, pumping, pouring, emitting, emptying, dumping, or otherwise disposing of any Hazardous Substance into the environment resulting in any material violation of any Environmental Protection Law; in the case of clauses (ii) and (iii) above, where the effect of which could be reasonably expected to have a Material Adverse Effect.

Section 2.21. Restricted Third-Party Encumbrances. The easements owned by the Company referenced by numbers 47 through 56, inclusive, 73, 74 and 90 to Exhibit A to the Title Commitment are encumbered by Restricted Third-Party Encumbrances as reflected on Exhibit B to the Title Commitment. The information set forth in Part IV of Annex 3 to this Agreement with respect to the Property subject to such Restricted Third Party Encumbrances, the Company's use of such Properties and the nature of such Restricted Third Party Encumbrances is true, accurate and complete in all material respects. Other than those Properties listed in the first sentence of this Section 2.21 and described in Part IV of Annex 3 to this Agreement, the Company owns no Property which is subject to Restricted Third Party Encumbrances. Those Properties listed in the first sentence of this Section 2.21 and described in Part IV of Annex 3 to this Agreement are subject to no Restricted Third Party Encumbrances other than those reflected on Exhibit B to the Title Commitment. Such Restricted Third Party Encumbrances do not, and the exercise of such remedies as would foreclose or terminate the right or interest of the Company in or to such Property by the Persons who hold such Restricted Third Party Encumbrances would not be likely

to, individually or in the aggregate, have a material adverse effect upon the business, profits, Properties (taken as a whole) or condition (financial or otherwise) of the Company or the ability of the Company to consummate the Transactions or perform its obligations set forth in this Agreement, the Bonds or the Indenture.

The easements referenced by numbers 91 through 93, inclusive, to Exhibit A to the Title Commitment are grants by the fee owners of the Properties underlying such easements of general Utility easements in favor of no specified Person. The Company has the right to use each of such easements for the purposes for which the Company is now using them.

nor shall any provision of this Section 8.2(b) entitle the holders of the Bonds to receive payments or other consideration equal or equivalent to the payments or other consideration made or given pursuant to clauses (A), (C) or (D), or to receive any right or benefit afforded to the holders of any other series of First Mortgage Bonds pursuant to clause (B) above, to which the holders of the Bonds would not otherwise be entitled.

(c) Binding Effect. Except as provided in Section 8.2(b) hereof, any amendment or waiver consented to as provided in this Section 8.2 shall apply equally to all holders of Bonds and shall be binding upon them and upon each future holder of any Bond and upon the Company whether or not such Bond shall have been marked to indicate such amendment or waiver.

New Mexico Utilities, Inc., a corporation organized under the laws of the State of New Mexico (hereinafter called the "Company," which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to , or registered assigns, on December 1, 2024, the sum of ($ ) (or so much thereof as shall not have been paid upon prior redemption) and to pay interest (computed on the basis of a 360 day year of twelve 30 day months) thereon from the later of the initial issuance of the series of Bonds of which this Bond is a part, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually on the first day of each June and December in each year commencing on the first Interest Payment Date next succeeding the date of this Bond until the principal amount thereof will be due and payable; provided that interest on any overdue principal, overdue Redemption Price, and (to the extent permitted by applicable law) overdue installments of interest, shall accrue at a rate equal to the lesser of (a) the highest rate allowed by applicable law, or (b) 7.10% per annum. In no event shall the interest payable on this Bond (including any interest on overdue interest or any overdue Redemption Price) exceed the maximum amount which the Holder hereof may legally collect under the then applicable usury law. In the event that it is hereinafter determined by a court of competent jurisdiction that the interest payable under this Bond (including any interest on overdue interest or any overdue Redemption Price) is in excess of the amount which the Holder hereof may legally collect under the then applicable usury law, then (i) all interest actually paid (including any interest on overdue interest or any overdue Redemption Price) in excess of the maximum amount legally collectible by such Holder shall be applied to the payment of principal of this Bond or, if all principal shall previously have been paid, promptly repaid by such Holder to the Company and (ii) interest on this Bond (including any interest on overdue interest or any overdue Redemption Price) subsequent to the date of such determination shall be reduced to the maximum amount which it is determined that the Holder may collect under the then applicable usury law.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in said Indenture, be paid to the Person (the "Registered Holder") in whose name this Bond (or one or more Predecessor Bonds, as defined in said Indenture) is registered at the close of business on the Regular Record Date for such interest, which shall be the fifteenth (15th) day (whether or not a Business Day) of the calendar month next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Registered Holder on such Regular Record Date, and may be paid to the Person in whose name this Bond (or one or more Predecessor Bonds) is registered at the close of business on a Special Record Date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof being given to Bondholders not less than ten (10) days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Bonds of this series shall be listed, if any, and upon such notice as shall be required by such exchange, all as more fully provided in said Indenture. The Trustee shall give notice of such Special Record Date and pay or arrange for payment of such defaulted interest as promptly as possible following receipt of or availability of funds for such purpose.

The principal, Make-Whole Amount, if any, and the Redemption Price of, and the interest on, this Bond shall be payable by the method and at the address specified for in Annex 1 to the Bond Purchase Agreement described below or by such other method or at such other address as the Registered Holder thereof shall have specified in writing. All such payments shall be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

If any payment due on, or with respect to, this Bond shall fall due on a day other than a Business Day, then such payment shall be made on the first Business Day following the day on which such payment shall have so fallen due; provided that if all or any portion of such payment shall consist of a payment of interest, for purposes of calculating such interest, such payment shall not be deemed to have been originally due on such first following Business Day, and such interest shall accrue and be payable only to the Interest Payment Date.

This Bond is one of a duly authorized issue of Bonds of the Company designated as its "First Mortgage Bonds" (herein called the "Bonds"), issued and to be issued in one or more series under, and all equally and ratably secured by, an Indenture of Mortgage dated February 14, 1992 (the "Original Indenture"), between the Company and Xxxxx Fargo Bank, N.A., as Trustee (herein called the "Trustee," which term includes any successor Trustee), as amended and supplemented by (i) that certain First Supplement to Indenture of Mortgage dated February 14, 1992 (the "First Supplemental Indenture"), dated as of May 15, 1992, (ii) that certain Second Amendment and Supplement to Indenture of Mortgage dated February 14, 1992 (the "Second Supplemental Indenture"), dated as of October 21, 1996 and (iii) that certain Third Amendment and Supplement to the Indenture of Mortgage dated February 14, 1992 (the "Third Supplemental Indenture"), dated as of December 15, 2004 (such Original Indenture, as so amended by the First Supplemental Indenture, the Second Supplemental Indenture and the Third Supplemental Indenture, being herein called the "Indenture") to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the properties thereby mortgaged, pledged and assigned, the nature and extent of the security, the respective rights thereunder of the Holders of the Bonds, the Trustee and the Company and the terms upon which the Bonds are, and are to be, authenticated and delivered. This Bond is issued under and pursuant to the terms and provisions of the separate Bond Purchase Agreements dated as of December 15, 2004 (the "Bond Purchase Agreement") among the Company, Southwest Water Company and each Purchaser named therein. Capitalized terms not otherwise defined herein are defined as provided in the Indenture.

As provided in the Indenture, the Bonds are issuable in series which may vary as in the Indenture provided or permitted. This Bond is one of the series specified in its title.

This Bond is subject to redemption in whole, at any time, and in part, from time to time, before its maturity in the following events and in the manner provided in Article V and Section 17.03 of the Indenture:

(1) at any time after issuance, at the option of the Company evidenced by a Board Resolution at a Redemption Price equal to 100% of the principal amount of this Bond to be redeemed, together with the Make-Whole Amount, if any, and interest accrued to the Redemption Date, and on a Redemption Date specified by the Company as provided in Section 5.02 of the Indenture; and

(2) from Major Event Proceeds, at a Redemption Price equal to 100% of the principal amount of this Bond to be redeemed, together with interest accrued to the Redemption Date, and on a Redemption Date that is the first date for which notice of redemption can be given by the Trustee as provided in Article V of the Indenture; provided, however, that such redemption may only be made if this Bond is redeemed pro rata with all other Outstanding Bonds of whatever series.

It is provided in the Indenture that Bonds of this series that the aggregate principal amount of any required or optional partial redemption of the Series C Bonds be allocated in units of $1,000 or multiples thereof on a pro rata basis among the holders of the Series C Bonds and that upon any partial redemption of any such Bond the same shall, except as otherwise permitted by the Indenture, be surrendered in exchange for one or more new Bonds in authorized form for the unredeemed portion of principal. Bonds (or portions thereof as aforesaid) for whose redemption and payment provision is made in accordance with the Indenture shall thereupon cease to be entitled to the lien of the Indenture and shall cease to bear interest from and after the date fixed for redemption.

If an Event of Default, as defined in the Indenture, shall occur, the principal of the Bonds may become or be declared due and payable in the manner and with the effect provided in the Indenture whereupon all principal, accrued interest and the Make-Whole Amount, if any, shall be due and payable,

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Bonds under the Indenture at any time by the Company with the consent of the Holders of 66²/3% in aggregate principal amount of the Bonds of each series at the time Outstanding affected by such modification; provided that the Supplemental Indenture establishing any such series may provide for the consent of the Holders of a different percent in aggregate principal amount of the Bonds of such series at the time Outstanding. The consent of the Holders of 70% in aggregate principal amount of the Series C Bonds at the time Outstanding is required to approve any such modification affecting the Series C Bonds. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of Bonds at the time Outstanding on behalf of the Holders of all the Bonds, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Bond and of any Bond issued upon the transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Bond.

No reference herein to the Indenture and no provision of this Bond or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Bond at the times, places and rates, and in the coin or currency, herein prescribed.

The Bonds of this series are issuable only as registered Bonds without coupons in denominations of $1,000.00 or any multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Bonds of this series are exchangeable for a like aggregate principal amount of Bonds of this series of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any transfer or exchange hereinbefore referred to, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

A-3

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Bond is registered as the owner hereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Bond shall be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this Bond shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this Bond to be duly executed under its corporate seal.

Re: New Mexico Utilities, Inc.
$12,000,000 First Mortgage Bonds, Series C

Ladies and Gentlemen:

We have been engaged as special counsel to New Mexico Utilities, Inc. (the "Company"), a New Mexico corporation, for purposes of rendering certain opinions under New Mexico law in connection with the Bond Purchase Agreement (the "Bond Purchase Agreement"), dated as of December 15, 2004, between the Company, joined for certain purposes by Southwest Water Company, a Delaware corporation ("Southwest"), and you, as Purchaser, which Bond Purchase Agreement provides, among other things, for the sale by the Company of its First Mortgage Bonds, Series C 6.10%, due December 1, 2024 (the "Series C Bonds") in the aggregate principal amount of $12,000,000 issued under and pursuant to an Indenture of Mortgage (the "Original Indenture"), dated as of February 14, 1992, between the Company and Xxxxx Fargo Bank, N.A., as successor to Sunwest Bank of Albuquerque, National Association, as trustee (the "Trustee"), as amended by a certain First Supplement to Indenture of Mortgage (the "First Supplemental Indenture") dated as of May 15, 1992, a certain Second Amendment and Supplement to Indenture of Mortgage (the "Second Supplemental Indenture") dated as of October 21, 1996, and a certain Third Amendment and Supplement to Indenture of Mortgage (the "Third Supplemental Indenture") dated as of December 15, 2004. The Original Indenture, the First Supplemental Indenture, the Second Supplemental Indenture and the Third Supplemental Indenture are herein sometimes referred to, collectively, as the "Indenture." The Indenture grants to the holders of the Company's first mortgage bonds from time to time issued thereunder, including the Series C Bonds, a security interest in certain property, whether presently owned or hereafter acquired, of the Company, more particularly described in the Indenture, consisting of both real property and real property interests, including, in each case, fixtures, other than Excepted Property, as described (the "Real Property"), and personal property, other than Excepted Property, as described (the "Personal Property"). We were also engaged to represent the Company in certain proceedings before the New Mexico Public Regulation Commission (the "NMPRC") regarding the issuance and sale of the Series C Bonds and related transactions. The terms used in our opinion and not defined herein shall have the respective meanings ascribed to them in, or pursuant to the provisions of the Bond Purchase Agreement or the Indenture.

In the course of our engagement, we have reviewed executed copies of the Bond Purchase Agreement, the Indenture, the Financing Statements and various certificates and other documents executed and delivered in connection therewith, and each of the executed and authenticated Series C Bonds, prior to the delivery of this letter, by each entity whose signature is provided for therein.

We have also made such legal and factual examinations and inquiries, including an examination of originals or copies certified or otherwise identified to our satisfaction as being true copies, of such instruments, corporate records and other documents as we have deemed necessary or appropriate for the purposes of this opinion.

As to factual matters and the authentication of instruments and other documents relevant to the opinions expressed below, we have, with your consent, relied upon certificates of public officials and officers of the Company, without conducting independent investigations with respect thereto.

In addition, we have, with your consent, relied upon certain other matters as described below in rendering certain of the opinions set forth below. We express no opinion as to the application of the laws of any State other than New Mexico, nor as to the application or requirements of any federal securities laws or regulations.

On the basis of the foregoing and in reliance thereon and on such other matters as are hereinafter specified, we are of the opinion that, as of the date hereof:

1. The Series C Bonds conform to the requirements of the Indenture.

2. The Company has complied with all conditions precedent to the issuance, sale and delivery of the Series C Bonds imposed by the provisions of the Indenture.

3. The Company is a corporation duly incorporated, legally existing, and in good standing under the laws of the State of New Mexico and has all requisite corporate power and authority to execute and deliver the Bond Purchase Agreement and the Indenture, to issue, sell and deliver the Series C Bonds, to perform its obligations pursuant to the Bond Purchase Agreement, the Series C Bonds and the Indenture, to carry on its business as now conducted by it in the State of New Mexico, and to own the Real Property and the Personal Property which it now owns.

4. The Indenture has been duly authorized by proper corporate action of the Company's Board of Directors and has been duly executed and delivered on behalf of the Company by its duly authorized officers. The Indenture constitutes a legal, valid and binding instrument of the Company enforceable in accordance with its terms, except to the extent that enforcement thereof may be limited by (i) the laws of the State of New Mexico (where the property covered thereby is situated) affecting the remedies for the enforcement of the liens and security interests provided for therein, which laws in our opinion do not make inadequate the remedies necessary for the realization of the benefits of such security; (ii) bankruptcy, insolvency, reorganization, moratorium or other similar laws of general application relating to or affecting the enforcement of creditors' rights; and (iii) general principles of equity. The Real Property now owned by the Company has been subjected to the terms of the New Mexico Deed of Trust Act (N.M. Stat. Xxx. §§ 48-10-1 et seq.) by the Indenture, and, subject to continuing compliance with the requirements of that act, the Trustee has a power of sale under which such Real Property may be sold as provided in the act. No action by the stockholder of the Company is required by law, by the Articles of Incorporation of the Company or by the By-Laws of the Company for the authorization, execution and delivery of the Indenture.

5. The Bond Purchase Agreement has been duly authorized by proper corporate action of the Company's Board of Directors and has been duly executed and delivered on behalf of the Company by its duly authorized officers. Except to the extent that enforcement may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or other similar laws of general application relating to or affecting the enforcement of creditors' rights, and (ii) general principles of equity, the Bond Purchase Agreement constitutes a legal, valid and binding instrument of the Company enforceable in accordance with its terms. No action by the stockholder of the Company is required by law, by the Articles of Incorporation of the Company or by the By-Laws of the Company for the authorization, execution and delivery of the Bond Purchase Agreement.

6. The Series C Bonds in the aggregate principal amount of $12,000,000 being purchased on the date hereof have been duly authorized by proper corporate action of the Company's Board of Directors, have been duly executed and delivered on behalf of the Company by its authorized officers, have been duly issued by the Company and have been duly authenticated by the Trustee under the Indenture, and the obligations of the Company represented by the Series C Bonds are legal, valid and binding obligations of the Company which are enforceable in accordance with their terms, except to the extent that enforcement may be limited by (i) bankruptcy, insolvency,

B2-2

reorganization, moratorium or other similar laws of general application relating to or affecting the enforcement of creditors' rights, and (ii) general principles of equity. Subject to the qualifications in paragraph 2, above, with respect to the enforceability of the Indenture, the Series C Bonds are entitled to the benefit and security of the Indenture, equally and ratably with all First Mortgage Bonds of other series which may from time to time be issued pursuant to and secured by the Indenture in accordance with the terms thereof, except as to any sinking, amortization, improvement, or other analogous fund established in accordance with the provisions of the Indenture.

7. Neither (a) the execution and delivery by the Company of the Bond Purchase Agreement or the Indenture; nor (b) the granting to the Trustee of liens upon certain collateral pursuant to the provisions of the Indenture; nor (c) the execution, delivery, issue and sale of the Series C Bonds; nor (d) compliance by the Company with the terms of the Series C Bonds, the Indenture and the Bond Purchase Agreement (all such transactions referred to in clauses (a) through (d), inclusive, of this paragraph 5 being hereinafter referred to as the "Transactions") will conflict with, or result in any breach of any of the provisions of, or constitute a default under, or result in the creation or imposition of any lien (other than the lien of the Indenture) upon, any of the Real Property or Personal Property of the Company pursuant to (i) the provisions of the Articles of Incorporation or By-Laws of the Company; (ii) any agreement or other instrument, known to us after due inquiry, to which the Company is a party or by which it or any of its Property is bound; (iii) any United States federal law, statute or regulation or New Mexico law, statute, regulation or ordinance; or (iv) any order, judgment, award or decree, known to us after due inquiry of the Company (no independent search of court records having been made) of any court or arbitrator against or affecting the Company or any of its property.

8. The Indenture (including the Third Supplemental Indenture) is in due form for recording and has been duly filed for record as a mortgage on the Real Property in each and every public office in which such recording is a prerequisite to the establishing of record of the lien thereof on the Real Property therein specifically described which is now owned by the Company. All taxes and fees required to be paid with respect to the execution and recording of the Indenture and the issuance of the Series C Bonds have been paid. The Indenture will not have to be refiled, reregistered or redeposited to continue the lien in and upon the Real Property now owned by the Company and specifically described therein or the effectiveness of such lien as against any subsequent transferee of the Real Property specifically described therein.

9. The Indenture constitutes a valid mortgage lien on the Real Property now owned by the Company which is specifically or generally described in the granting clauses of the Indenture as being subject to the lien thereof and which is located in Bernalillo County, New Mexico. We express no opinion as to the attachment of the lien of the Indenture on Real Property acquired after the date and time of recording. The opinion in this paragraph is given in partial reliance on Title Insurance Policy No. 34-4042-61-001004 dated March 11, 1992, and Title Policy No. 32-0047-061-00000006 dated November 4, 1996 each issued by Ticor Title Insurance Company, and upon the written commitment of Fidelity National Title Insurance Company dated November 1, 2004 for the issuance of a new policy of title insurance with the amount of coverage of $12,000,000 to insure the Trustee and the holders of the Series C Bonds against loss or damage to the extent of $12,000,000 in the event of any defect in the lien of the Indenture or the Real Property or by reason of the title to such Real Property described in the Indenture being other than as shown in such commitment.

10. The provisions of the Indenture are effective to create a valid security interest in favor of the Trustee in the Personal Property of the Company. The Indenture, as a financing statement, or a separate financing statement in respect of the Personal Property (the term "Financing Statement" referring to either or both as the case may be) has been duly filed or recorded in each and every

B2-3

public office in which such filing and/or recording is a prerequisite to the establishing of record of the lien of the Indenture on all of the Personal Property therein specifically described which is owned by the Company. Based upon the issuance and sale by the Company to you prior to the delivery of this letter of the Series C Bonds and your concurrent delivery of the consideration provided for in the Bond Purchase Agreement, pursuant to the provisions of the Indenture the Trustee has a valid, perfected security interest in the Personal Property presently owned by and in the possession of the Company or hereafter acquired by the Company. Our opinion as to perfection, however, is expressly limited to those items and types of the Personal Property as to which perfection is accomplished by the filing of a financing statement in accordance with the Uniform Commercial Code-Secured Transactions (N.M. Stat. Xxx. §§ 9-101 et seq. (1978)) as in effect in New Mexico ("UCC Article 9"). Such security interest is, in the case of after-acquired Personal Property, subject to purchase money security interests and acquisition by the Company of rights in and possession of such Personal Property. Except for the timely filing of continuation statements as required by UCC Article 9 and the filing of appropriate amendments to the Financing Statements required by changes in circumstances, it is not necessary to refile the Financing Statements or to file new financing statements to maintain the perfection of the security interests in the Personal Property.

Based upon the assumptions and subject to the limitations set forth in this paragraph, insofar as such security interest relates to that portion of the Personal Property which is personal property owned and possessed by the Company as of the date hereof and located in the State of New Mexico and, in the case of fixtures, in Bernalillo County, New Mexico, such security interest will have priority over all other security interests in any of such Personal Property which may be perfected under UCC Article 9 by filing with the New Mexico Secretary of State or the County Clerk of Bernalillo County, New Mexico, a financing statement covering such Personal Property subsequent to the date hereof, except as such priority is or may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or other similar laws or case decisions relating to or affecting the enforcement of the rights of creditors generally. The opinions in this paragraph 8 are, as to Personal Property acquired after the date of this letter, expressly subject to pre-existing liens and encumbrances. Such opinions are also given in reliance upon a certificate of an officer of the Company to the effect that all of such Personal Property has been continuously located in the State of New Mexico since at least January 1, 2004, and that no other security interest in any of such Personal Property exists by a certificate of title or ownership issued under the laws of any state other than New Mexico. In addition, in giving such opinions we have relied, in part, upon a certificate from an officer of the Company to the effect that the Company has not, during the period from January 1, 2004 to the date hereof, created any "purchase money security interest," as defined in UCC Article 9 (N.M. Stat. Xxx. §§ 00-0 -000 (1978)) in any portion of the Personal Property. Finally, we have relied on the reports of UCC and other lien searches and we are relying upon the accuracy of such reports as to the absence of filing of any financing statements or notices against the Company except as shown in such reports. We have made no independent examination of the public records and indices covered by such reports and consequently express no opinion as to the priority of the Trustee's security interest under the Indenture as against the interest of any other secured party which, prior to the filing of the Financing Statements, filed a financing statement or notice not reported in such reports.

11. All consents, approvals or authorizations, if any, of or by any Governmental Authority required on the part of the Company in connection with the consummation of the Transactions have been duly obtained, and the Company has complied with all applicable provisions of law requiring any designation, declaration, filing, registration or qualification with any Governmental Authority in connection with the Transactions.

B2-4

12. All approvals and consents of the NMPRC required for the valid issuance and sale of the Series C Bonds, the valid execution and delivery of the Bond Purchase Agreement by the Company, the valid execution and delivery of the Third Supplemental Indenture by the Company pursuant to and in accordance with the terms and conditions of the Bond Purchase Agreement and the Indenture, the granting to the Trustee of liens upon certain collateral, in each case, pursuant to the provisions of the Second Supplemental Indenture, and the compliance by the Company with the terms of the Series C Bonds, the Indenture and the Bond Purchase Agreement have been obtained and have become effective. All appeal periods applicable to the effectiveness of such approvals and consents have expired. There is in effect no stop order or other order of the NMPRC denying, suspending or revoking the effectiveness of any such approvals and consents, and no proceedings for such purposes are pending or, to our knowledge, threatened before the NMPRC.

13. There is no litigation or proceeding, known to us after due inquiry of the Company (no independent search of court records having been made), pending or threatened against the Company not disclosed in the Bond Purchase Agreement or the financial statements of the Company which have been furnished to you pursuant thereto in which a judgment, order or award is likely that could be materially adverse to the Company or that could affect the ability of the Company to consummate the Transactions or perform its obligations under the Bond Purchase Agreement or the Indenture.

14. The Company has complied with all conditions precedent to the consummation of the Transactions imposed by law.

15. To the best of our knowledge, the Company is not in violation of any applicable federal, state or other law or regulation which would have a material adverse effect on the business of the Company.

The certificates of officers or other representatives of the Company upon which we have relied which are referred to in this opinion are being delivered to you in connection with the closing proceedings.

To the extent that the obligations of the Company may be dependent upon such matters, we have assumed for the purposes of our opinions that the Bond Purchase Agreement has been duly authorized, executed and delivered by each of you and constitutes your respective legal, valid and binding obligation enforceable in accordance with its terms; and that each of you has the requisite corporate or other organizational power and authority to perform your respective obligations under the Bond Purchase Agreement. For the purposes of our opinions we have also relied upon the opinion of counsel to the Trustee to the effect that the Third Supplemental Indenture has been duly executed and delivered by the Trustee, that the Trustee has the requisite corporate or other organizational power and authority to perform its obligations under the Indenture, and that the Trustee has duly authenticated the Series C Bonds under the Indenture.

We note specifically that certain of the representations and warranties made to you or in your favor contained in the Bond Purchase Agreement have been made by Southwest rather than by the Company itself. In our view, the fact that such representations and warranties have been made by Southwest rather than the Company will not affect our opinions as to the validity or enforceability of the Bond Purchase Agreement or the Indenture or prevent the exercise by the Trustee of the remedies afforded to it by the Indenture upon a default arising from the breach of any representation or warranty made by Southwest in the Bond Purchase Agreement. Such opinion is based, in part, upon the opinion of Xxxxxx & Xxxxxxx LLP of even date to the effect that the Bond Purchase Agreement has been ratified and approved by proper corporate action of Southwest's board of directors and has been duly executed and delivered on behalf of Southwest by its duly authorized officers.

B2-5

This letter is provided to you solely in connection with the transactions described herein and may not be published or disseminated in any way without our prior written consent; the foregoing shall not, however, preclude reliance upon this opinion by Xxxxxx & Xxxxxxx LLP and Xxxxxxx and Xxxxxx LLP, delivery of this opinion to or reliance upon this opinion by any governmental authorities having regulatory jurisdiction over you or delivery of this opinion to or reliance upon this opinion by any subsequent Holder of the Series C Bonds who becomes a Holder in compliance with the provisions of the Bond Purchase Agreement and the Indenture.

To the Parties Listed on Attached Schedule A

$12,000,000 First Mortgage Bonds, Series C 6.10%
Due December 1, 2024
Of New Mexico Utilities, Inc.

Ladies and Gentlemen:

I am Senior Counsel for Xxxxx Fargo & Company, the parent corporation of Xxxxx Fargo Bank, National Association, a national banking association. As such, I have reviewed the provisions of a Third Amendment and Supplement to Indenture of Mortgage dated as of December 1, 2004 (the "Third Supplemental") between New Mexico Utilities, Inc. (the "Company") and Xxxxx Fargo Bank, National Association, as Trustee (the "Trustee"), amending and supplementing that certain Indenture of Mortgage dated as of February 14, 1992 as previously amended and supplemented (together with the Third Supplemental, the "Indenture") between the Company and the Trustee. In addition, I am generally familiar with the Articles of Association and the Bylaws of the Trustee and am also familiar with the corporate proceedings of the Trustee with regard to its authorization, execution and delivery of the Indenture. Capitalized terms used herein shall have the respective meanings ascribed to them in the Indenture, except as otherwise defined herein.

For purposes of this opinion, I have assumed the genuineness of all signatures, the authenticity of all documents submitted to me as originals, and the conformity with originals of all documents submitted to me as copies. In making my examination of documents executed by entities other than the Trustee, I have assumed that each such other entity had the power to enter into and perform all its obligations thereunder, and also have assumed the due authorization of all requisite action and due execution of such documents by each such entity. Where questions of fact material to my opinions expressed below were not established independently, I have relied upon statements of officers of the Trustee as contained in their certificates.

Based upon the foregoing, I am of the opinion that:

1. The Trustee is a national banking association duly organized, validly existing and in good standing under the laws of the United States of America.

2. The Trustee is duly eligible and qualified to act as Trustee under the Indenture.

3. The Trustee has all requisite power, authority and legal right to execute and deliver the Indenture and to perform its obligations under the Indenture, and has taken all necessary corporate action to authorize the execution and delivery of and the performance of its obligations under the Indenture.

4. The Trustee has duly executed and delivered the Indenture. Assuming the due authorization, execution and delivery thereof by the Company, the Indenture is the legal, valid and binding agreement of the Trustee enforceable in accordance with its terms, except to the extent enforceability thereof may be subject to (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws affecting creditors' rights and remedies heretofore or hereafter enacted, and (ii) the application of equitable principles and the exercise of judicial discretion in appropriate cases.

5. The Company's First Mortgage Bonds, Series C 6.10%, Due December 1, 2024 have been duly authenticated by the Trustee.

6. The execution, delivery and performance of the Indenture does not now, and will not upon consummation of the transaction contemplated thereby in accordance with the existing terms thereof conflict with, result in a breach of or constitute a default under, any term or provision of the Articles of Association or Bylaws of the Trustee, any existing term or provision of any agreement, contract, instrument or indenture of any nature whatsoever, known to me, to which the Trustee is a party or by which it is bound; or, to the best of my knowledge after due inquiry, any existing order, judgment, writ, injunction or decree of any court or governmental authority having jurisdiction over the Trustee, nor will it conflict with or constitute a breach of or default under any law or administrative regulation to which the Trustee is subject (except that no representation, warranty or agreement is made herein with respect to any federal or state securities or Blue Sky laws or regulations) or result in the creation or imposition of any lien, charge or other security interest or encumbrance of any nature whatsoever upon any of the property or assets of the Trustee.

7. To the best of my knowledge after due inquiry, there are no actions, proceedings or investigations pending or threatened against the Trustee before any court, administrative agency or tribunal (i) asserting the invalidity of the Indenture (ii) seeking to prevent the consummation of any of the transactions contemplated thereby or (iii) that might materially and adversely affect the performance by the Trustee of its obligations under, or the validity or enforceability of the Indenture. For purposes of the foregoing, I have not regarded any actions, proceedings or investigations "threatened" unless the potential litigants or governmental authority has manifested to a member of the Xxxxx Fargo & Company Law Department having responsibility for litigation matters involving the corporate trust activities of the Trustee present intention to initiate such proceedings.

I advise you that I am admitted to practice in the State of Utah (the "State"), and do not purport to be an expert in or generally familiar with or qualified to express legal opinions based on the laws of any jurisdiction other than the federal laws of the United States ("Federal") and the State. In giving these opinions I have assumed with your permission that the applicable laws of the State of New Mexico do not differ in any material respect from applicable Federal and State laws. These opinions are further limited to such State and Federal laws in effect as of the date hereof.

The foregoing opinions are being furnished to you solely for your benefit and that of your counsel and may not be relied upon by, nor may copies be delivered to, any other person without my prior written consent.

		Very truly yours,


		Xxxxx X. Xxxxxxxx Senior Counsel

Re: $12,000,000 First Mortgage Bonds, Series C 6.10%,
due October 1, 2024
of
New Mexico Utilities, Inc.

[Purchasers]

Ladies and Gentlemen:

We have acted as your special counsel in connection with your purchase from New Mexico Utilities, Inc., a New Mexico corporation (the "Company"), of the above-captioned $12,000,000 aggregate principal amount of First Mortgage Bonds, Series C 6.10%, due December 1, 2024 (the "Bonds") pursuant to the separate Bond Purchase Agreements dated as of December 15, 2004 (the "Agreement"), among the Company, Southwest Water Company and each of you. The Bonds are issued under an Indenture of Mortgage dated February 14, 1992 (hereinafter called the "Original Indenture"), between the Company and the trustee named therein, as supplemented and amended by three indentures supplemental thereto and amendatory thereof, including the Third Amendment and Supplement to Indenture of Mortgage dated February 14, 1992 (the "Third Supplement") dated as of December 15, 2004 entered into by the Company and Xxxxx Fargo Bank, N.A., a national banking association, as trustee (the "Trustee"). The Original Indenture and the three supplemental indentures thereto are hereinafter collectively called the "Indenture". Capitalized terms used herein which are not otherwise defined shall have the meanings set forth in the Agreement.

We have examined the Indenture, the Agreement, the Bonds delivered to you and such charter documents, corporate records, certificates of public officials and of officers of the Company and such other documents and showings and related matters of law as we have deemed necessary to enable us to give the opinion hereinafter set forth. We have also read the opinions of (i) Xxxxxx & Xxxxxxx LLP, counsel for the Company, (ii) Xxxxxxxxxx & Xxxxxxx, special counsel for the Company and (iii) Xxxxx Xxxxxxxx, Senior Counsel for the Trustee, delivered to you pursuant to the Agreement. We believe that the opinions referred to in the foregoing clauses (i)-(iii) are satisfactory in scope and form and that you are justified in relying thereon. In rendering the opinion set forth in paragraph 1 below, we have relied solely upon an examination of the Articles of Incorporation of the Company certified by the Corporate Secretary of the Company, a Certificate of Good Standing of the Company from the Secretary of State of the State of New Mexico and the By-laws of the Company. For the purposes of this opinion letter and with your consent, we have expressed our opinions herein with respect to matters of state law as if the laws of the State of Illinois applied (although the Company is a New Mexico corporation and the Agreement, the Indenture and the Bonds state that they are governed by the laws of the State of New Mexico). Accordingly, our opinions are limited to the laws of the State of Illinois and the Federal laws of the United States of America and we express no opinion on the laws of any other jurisdiction.

Based upon the foregoing, we are of the opinion that:

1. The Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the State of New Mexico and has the corporate power and authority to issue and sell the Bonds.

2. The Third Supplement and the Bonds have been duly authorized, executed and delivered by the Company.

3. The Agreement has been duly authorized, executed and delivered by the Company and constitutes a legal, valid and binding obligation, contract and agreement of the Company

enforceable against the Company in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws or equitable principles relating to or limiting creditors' rights generally.

4. The issuance, sale and delivery of the Bonds under the circumstances contemplated by the Agreement do not, under existing law, require the registration of the Bonds under the Securities Act of 1933, as amended, or the qualification of the Indenture under the Trust Indenture Act of 1939, as amended.

In rendering our opinion, we have made no independent examination of title to property of the Company purported to be owned by it, the validity and sufficiency of the franchises or other governmental authorizations under which the Company operates, the priority of the lien created by the Indenture, the absence of liens or encumbrances on property of the Company, or the form (for purposes of recordation) of the Indenture.

Respectfully submitted,
