Dear Sirs:
    
          Texas-New Mexico Power Company, a Texas corporation (the "Company"),
proposes to issue and sell $   ,000,000 aggregate principal amount of its
     % Senior Notes due      (the "Securities") to the several underwriters
named in Schedule I hereto (the "Underwriters"). The Securities are described in
the Prospectus which is referred to below and are to be issued pursuant to the
provisions of an indenture (the "Indenture") to be dated as of January 1, 1999
between the Company and Chase Bank of Texas, National Association, as trustee
(the "Trustee"). Until the Release Date (as defined in the Indenture), the
Securities will be secured as to payment of principal and interest by one or
more series of First Mortgage Bonds (the "First Mortgage Bonds") issued, pledged
and delivered by the Company to the Trustee. The First Mortgage Bonds will be
issued pursuant to the provisions of the Company's Indenture of Mortgage and
Deed of Trust dated as of November 1, 1944 between Community Public Service Co.,
a Delaware corporation (which was merged into and whose obligations were assumed
by the Company), and City National Bank and Trust Company of Chicago, Chicago,
Illinois (the current successor of which is U.S. Bank Trust, N.A.) (the
"Mortgage Trustee"), as heretofore supplemented and modified, and as
supplemented by the Twenty-Sixth Supplemental Indenture (herein so called)
thereto, dated as of    , 1999 between the Company and the Mortgage Trustee (as
so supplemented and modified, the "Mortgage Indenture").     

          Section 1.  Registration Statement and Prospectus. The Company has
prepared and filed with the Securities and Exchange Commission (the
"Commission") in accordance with the provisions of the Securities Act of 1933,
as amended, and the rules and regulations of the Commission thereunder
(collectively, the "Act"), a registration statement on Form S-3 (Registration
No. 333-64215), including a prospectus subject to completion, relating to the
Securities, which will be amended from time to time. The registration statement,
as amended at the time it became effective, including all documents or
information incorporated or deemed to be incorporated by reference therein is
referred to as the "Registration Statement"; and the prospectus in the form
first used to confirm sales of Securities (including (a) the information
contained in any prospectus supplement relating to the securities or deemed to
be part of the Registration Statement at effectiveness pursuant to Rule 430A or
Rule 434 of the Act, and (b) any documents or information incorporated or deemed
to be incorporated by reference into such prospectus), is hereinafter referred
to as the "Prospectus". Any registration statement (including any amendment or
supplement thereto or information which is deemed to be a part thereof) filed by
the Company under Rule 462(b) of the Act (a "Rule 462(b) Registration
Statement") shall be deemed to be part of the Registration Statement. If the
Company elects to rely on Rule 434 under the Act, all references to the
Prospectus shall be deemed also to include, without limitation, the form of
prospectus and term sheet (a "Term Sheet"), taken together, provided to the
Underwriters by the Company in reliance on Rule 434 under the Act (the 

 
"Rule 434 Prospectus"). All references in this Agreement to financial statements
and schedules and other information which is "contained," "included,"
"described" or "stated" in the Registration Statement or the Prospectus (and all
references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which is or is deemed
to be incorporated by reference in the Registration Statement or the Prospectus,
as the case may be; and all references in this Agreement to amendments or
supplements to the Registration Statement or the Prospectus shall be deemed to
mean and include, without limitation, even though not specifically stated, any
document filed under the Securities Exchange Act of 1934, as amended, and the
rules and regulations of the Commission thereunder (the "Exchange Act") which,
upon filing, is or is deemed to be incorporated by reference in the Registration
Statement or the Prospectus after the effective date, as the case may be.
    
          Section 2.  Agreements to Sell and Purchase. On the basis of the
representations and warranties contained in this Agreement, and subject to its
terms and conditions, the Company agrees to issue and sell, and each Underwriter

of delivery.     

          Section 3.  Terms of Public Offering. The Company is advised by you

     or which requires any additions to or changes in the Registration Statement
     or the Prospectus (as then amended or supplemented) in order to make the
     statements therein not misleading. If at any time the Commission shall
     issue any stop order suspending the effectiveness of the Registration
     Statement, the Company will use its reasonable best efforts to obtain the
     withdrawal or lifting of such order at the earliest possible time.

     thereof as such Underwriter or dealers may reasonably request.

     law, regulation or rule or any decree, judgment or order applicable to the
     Company or any of its Subsidiaries (except for any default or breach that
     would not, singly or in the aggregate, have a material adverse effect on
     the business, financial condition or results of operations of the Company
     and its Subsidiaries, taken as a whole).

          (k) Neither the Company nor any of its Subsidiaries is in violation of
     any law, ordinance, governmental rule or regulation or court decree to
     which it may be subject (including any federal, state, or local law or
     regulation relating to the protection of human health and safety, the
     environment or hazardous or toxic substances or wastes, pollutants or
     contaminants (collectively, "Environmental Laws")), which violation might
     have a material adverse effect on the business, financial condition or
     results of operations of the Company and its Subsidiaries, taken as a
     whole.

          (l) In the ordinary course of its business, the Company and its
     Subsidiaries conduct a periodic review of the effect of Environmental Laws
     on the business, operations and properties of the Company and its
     Subsidiaries, in the course of which they identify and evaluate associated
     costs and liabilities (including, without limitation, any capital or
     operating expenditures required for clean-up, closure of properties or
     compliance with Environmental Laws or any permit, license or approval, any
     related constraints on operating activities and any potential liabilities
     to third parties). On the basis of such review, the Company has reasonably
     concluded that such associated costs and liabilities would not, except to
     the extent properly accrued for in the Company's financial statements,
     singly or in the aggregate, have a material adverse effect on the business,
     financial condition or results of operations of the Company and its
     Subsidiaries, taken as a whole.

                                       7

 
          (m) The Company is not an "investment company" or a company
     "controlled" by an "investment company" within the meaning of the
     Investment Company Act of 1940, as amended.

          (n) The filing of the Registration Statement and the consummation of
     the transactions contemplated hereby and by the Prospectus have been duly
     authorized by the Company; and this Agreement has been duly authorized,
     executed and delivered by the Company and is a legal, valid and binding
     obligation of the Company.

          (o) The Indenture and the Mortgage Indenture filed as exhibits to the
     Registration Statement conform, and the Securities and the First Mortgage
     Bonds will conform, in all material respects to the description thereof
     contained in the Registration Statement and Prospectus.

          (p) The Company has obtained the approval of the Federal Energy
     Regulatory Commission and the New Mexico Public Utility Commission with
     respect to the issuance and sale of the Securities; and no other approval,
     authorization, consent or order of or filing with any federal, state or
     local governmental or regulatory commission, court, board, body, authority
     or agency is required of the Company for the execution, delivery and
     performance of this Agreement, the Indenture and the Securities, or the
     pledge of the First Mortgage Bonds or the consummation of the transactions
     related to the issuance and sale of the Securities as contemplated hereby
     other than those obtained under the Act or the Trust Indenture Act and any
     necessary qualification under the securities or Blue Sky laws of the
     various jurisdictions in which the Securities are being offered by the
     Underwriters.

          (q) No person has the right, contractual or otherwise, to cause the
     Company to issue to it, or register pursuant to the Act, securities held by
     it who has not been notified of such right in respect of the Registration
     Statement.

          (r) Arthur Andersen LLP, and KPMG Peat Marwick, whose reports on the
     consolidated financial statements of the Company are filed with the
     Commission as part of the Registration Statement and Prospectus, are
     independent public accountants with respect to the Company and its
     Subsidiaries as required by the Act and the applicable published rules and
     regulations thereunder.

          (s) Each of the Company and its Subsidiaries has all licenses,
     authorizations, consents and approvals (each, an "Authorization") and has
     made all filings required under any federal, state or local law, regulation
     or rule, and has obtained all Authorizations from other persons, in order
     to conduct its business, except where the failure to have any such
     Authorization or to make any such filing would not, singly or in the
     aggregate, have a material adverse effect on the business, financial
     condition or results of operations of the Company and its Subsidiaries,
     taken as a whole; and neither the Company nor any of its Subsidiaries is in
     violation of, or in default under, any such Authorization or any federal,
     state or local law, regulation or rule or any decree, order or judgment
     applicable to the Company or any of its Subsidiaries the effect of which
     could have a material adverse effect on the business, financial condition
     or results of operations of the Company and its Subsidiaries, taken as a
     whole.

          (t) All legal or governmental proceedings, contracts or documents
     required to be described in the Registration Statement or the Prospectus or
     to be filed as an exhibit to the Registration Statement have been so
     described or filed as required or incorporated therein by reference as
     permitted by the rules and regulations of the Commission.

          (u) Except as disclosed in the Registration Statement and the
     Prospectus, there are no actions, suits or proceedings pending or, to the
     knowledge of the Company, threatened against the Company or any of its
     Subsidiaries or any of their respective properties, at law or in equity, or
     before or by any federal, state, local or foreign governmental or
     regulatory commission,

                                       8

 
     board, body, authority or agency which could result in a judgment, decree
     or order having a material adverse effect on the business, financial
     condition or results of operations of the Company and its Subsidiaries,
     taken as a whole, or which, to the best knowledge of the Company, after due
     inquiry, could affect the transactions contemplated by this Agreement and
     the Prospectus.

          (v) The consolidated financial statements included or incorporated by
     reference in the Registration Statement and the Prospectus present and (in
     the case of any amendment or supplement to any such document, or any
     material incorporated by reference in any such document, filed with the
     Commission after the date as of which this representation is being made)
     will present fairly, as of the Closing Date and at all times during which a
     Prospectus is required to be delivered under the Act, the consolidated
     financial condition of the Company and its Subsidiaries as of the dates
     indicated, consolidated results of operations and the cash flows of the
     Company and its Subsidiaries for the periods indicated; and such financial
     statements have been and (in the case of any amendment or supplement to any
     such document, or any material incorporated by reference in any such
     document, filed with the Commission after the date as of which this
     representation is being made) will be, as of the Closing Date and at all
     times during which a Prospectus is required to be delivered under the Act,
     prepared in conformity with generally accepted accounting principles.

          (w) Subsequent to the respective dates as of which information is
     given in the Registration Statement and Prospectus, and except as may be
     otherwise stated in the Registration Statement or Prospectus, there has not
     occurred (A) any material adverse change or any development involving a
     prospective material adverse change in the business, financial condition or
     results of operations of the Company and its Subsidiaries, taken as a
     whole, (B) any transaction, which is material to the Company and its
     Subsidiaries, taken as a whole entered into by the Company or any of its
     Subsidiaries or (C) any obligation, contingent or otherwise, directly or
     indirectly incurred by the Company or any of its Subsidiaries which is
     material to the Company and its Subsidiaries, taken as a whole.

          (x) Each of the Company and its Subsidiaries has good and marketable
     title to all properties and assets described in the Prospectus as owned by
     it, free and clear of all Liens, except such as are described in the
     Prospectus or are not material to the business, financial condition or
     results of operations of the Company and its Subsidiaries, taken as a
     whole; and each of the Company and its Subsidiaries has valid, subsisting
     and enforceable leases for the properties described in the Prospectus as
     leased by it, with such exceptions as are not material to the business,
     financial condition or results of operations of the Company and its
     Subsidiaries, taken as a whole and do not materially interfere with the use
     made and proposed to be made of such properties by the Company and its
     Subsidiaries.

          Section 7.  Indemnification. (a) The Company agrees to indemnify and
hold harmless each Underwriter, its directors, its officers and each person, if
any, who controls any Underwriter within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, from and against any and all losses, claims,
damages, liabilities and judgments (including, without limitation, any
reasonable legal or other expenses incurred in connection with investigating or
defending any matter, including any action, that could give rise to any such
losses, claims, damages, liabilities or judgments) caused by any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (or any amendment thereto), the Prospectus (as amended or
supplemented if the Company shall have furnished any amendment or supplement
thereto) or any preliminary prospectus, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or judgments are caused by any untrue
statement or omission or alleged untrue statement or omission based upon
information relating to any Underwriter furnished in writing to the Company by
or on behalf of the Underwriters through you expressly for use therein;
provided, however, that the foregoing indemnity agreement with respect to any
preliminary prospectus shall not inure to the

                                       9

 
benefit of any Underwriter (or to the benefit of any person controlling, or
controlled by, such Underwriter) who failed to deliver a Prospectus, as then
amended or supplemented (so long as the Prospectus and any amendment or
supplement thereto was provided by the Company to the several Underwriters in
the requisite quantity and on a timely basis to permit proper delivery on or
prior to the Closing Date) to the person asserting any losses, claims, damages,
liabilities or judgments caused by any untrue statement or alleged untrue
statement of a material fact contained in the preliminary prospectus, or caused
by any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, if
such material misstatement or omission or alleged material misstatement or
omission was cured in the Prospectus, as so amended or supplemented, and such
Prospectus was required by law to be delivered at or prior to the written
confirmation of sale to such person.

          (b) Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, its officers who sign the
Registration Statement and each person, if any, who controls the Company within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the
same extent as the foregoing indemnity from the Company to such Underwriter but
only with respect to information relating to such Underwriter furnished in
writing by or on behalf of such Underwriter through you expressly for use in the
Registration Statement (or any amendment thereto), the Prospectus (or any
amendment or supplement thereto) or any preliminary prospectus and in respect of
which indemnity may be sought against any Underwriter, the Underwriter shall
have the rights and duties given to the Company (except that if the Company
shall have assumed the defense thereof, such Underwriter shall not be required
to do so, but may employ separate counsel therein and participate in the defense
thereof but the fees and expenses of such counsel shall be at the expense of
such Underwriter), and the Indemnified Party shall have the rights and duties
given to the Underwriter, by Section 7(c) hereof.
    
          (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the
"Indemnified Party"), the Indemnified Party shall promptly notify the person
from whom such indemnity may be sought (the "Indemnifying Party") in writing and
the Indemnifying Party shall assume the defense of such action, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all fees and expenses of such counsel, as incurred (except that in
the case of any action in respect of which indemnity may be sought pursuant to
both Sections 7(a) and 7(b), the Underwriter shall not be required to assume the
defense of such action pursuant to this Section 7(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of such
Underwriter). Any Indemnified Party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of the Indemnified Party
unless (i) the employment of such counsel shall have been specifically
authorized in writing by the Indemnifying Party, (ii) the Indemnifying Party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the Indemnified Party or (iii) the named parties to
any such action (including any impleaded parties) include both the Indemnified
Party and the Indemnifying Party, and the Indemnified Party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
Indemnifying Party (in which case the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of the Indemnified Party).
In any such case, the Indemnifying Party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys (in addition to any local counsel) for all Indemnified Parties and all
such fees and expenses shall be reimbursed as they are incurred. Such firm shall
be designated in writing by                  , in the case of parties
indemnified pursuant to Section 7(a), and by the Company, in the case of parties
indemnified pursuant to Section 7(b). The Indemnifying Party shall indemnify and
hold harmless the Indemnified Party from and against any and all losses, claims,
damages, liabilities and judgments by reason of any settlement of any action (i)
effected with its written consent or (ii) effected without its written consent
if the settlement is entered into more than twenty business days after the
Indemnifying Party shall have received a request from the Indemnified Party for
reimbursement of the fees and expenses of counsel (in any case where     

                                       10

 
such fees and expenses are at the expense of the Indemnifying Party) and, prior
to the date of such settlement, the Indemnifying Party shall have failed to
comply with such reimbursement request. No Indemnifying Party shall, without the
prior written consent of the Indemnified Party, effect any settlement or
compromise of, or consent to the entry of judgment with respect to, any pending
or threatened action in respect of which the Indemnified Party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the Indemnified Party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the Indemnified Party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the Indemnified Party. No
Indemnifying Party will be liable for the costs and expenses of any settlement
of any pending or threatened action effected by the Indemnified Party without
the consent of the Indemnifying Party.

          (d) To the extent the indemnification provided for in this Section 7
is unavailable to an Indemnified Party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Underwriters on the other hand from the offering
of the Securities or (ii) if the allocation provided by clause 7(d)(i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause 7(d)(i) above but also the
relative fault of the Company on the one hand and the Underwriters on the other
hand in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and the Underwriters on the other hand shall be deemed to be in the
same proportion as the total net proceeds from the offering (after deducting
underwriting discounts and commissions but before deducting expenses) received
by the Company, and the total underwriting discounts and commissions received by
the Underwriters, bear to the total price to the public of the Securities, in
each case as set forth in the table on the cover page of the Prospectus. The
relative fault of the Company on the one hand and the Underwriters on the other
hand shall be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or the Underwriters and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

          The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Party as a result of the losses,
claims, damages, liabilities or judgments referred in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified Party
in connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments. Notwithstanding the provisions of this Section 7, no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations to contribute
pursuant to this Section 7(d) are several in proportion to the respective
principal amount of Securities purchased by each of the Underwriters hereunder
and not joint.

          (e) The remedies provided for in this Section 7 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
Indemnified Party at law or in equity.

                                       11

 
          Section 8.  Conditions of Underwriters' Obligations. The several
obligations of the Underwriters to purchase the Securities under this Agreement
are subject to the satisfaction of each of the following conditions:

          (a) All the representations and warranties of the Company contained in
     this Agreement shall be true and correct on the date hereof and on the
     Closing Date with the same force and effect as if made on and as of such
     dates.

          (b) On or after the date hereof, (i) there shall not have occurred any
     downgrading, suspension or withdrawal of, nor shall any notice have been
     given of any potential or intended downgrading, suspension or withdrawal
     of, or of any review (or of any potential or intended review) for a
     possible change that does not indicate the direction of the possible change
     in, any rating of the Company or any securities of the Company (including,
     without limitation, the placing of any of the foregoing ratings on credit
     watch with negative or developing implications or under review with an
     uncertain direction) by any "nationally recognized statistical rating
     organization" as such term is defined for purposes of Rule 436(g)(2) under
     the Act, (ii) there shall not have occurred any change, nor shall any
     notice have been given of any potential or intended change, in the outlook
     for any rating of the Company or any securities of the Company by any such
     rating organization and (iii) no such rating organization shall have given
     notice that it has assigned (or is considering assigning) a lower rating to
     the Securities than that on which the Securities were marketed.

          (c) You shall have received on the Closing Date a certificate dated
     the Closing Date, signed by Patrick Bridges and Paul Talbot, in their
     capacities as the Treasurer and Corporate Secretary of the Company,
     respectively, confirming the matters set forth in Sections 6(x), 8(a) and
     8(b) and that the Company has complied with all of the agreements and has
     satisfied all of the conditions herein contained and required to be
     complied with or to be satisfied by the Company on or prior to the Closing
     Date.

          (d) Since the respective dates as of which information is given in the
     Prospectus other than as set forth in the Prospectus (exclusive of any
     amendments or supplements thereto subsequent to the date of this
     Agreement), (i) there shall not have occurred any change or any development
     involving a prospective change in the business, financial condition or
     results of operations of the Company and its Subsidiaries, taken as a
     whole, (ii) there shall not have been any change or any development
     involving a prospective change in the capital stock or in the long-term
     debt of the Company or any of its Subsidiaries and (iii) neither the
     Company nor any of its Subsidiaries shall have incurred any liability or
     obligation, direct or contingent, the effect of which, in any such case
     described in clause 8(d)(i), 8(d)(ii) or 8(d)(iii), in your judgment, is
     material and adverse and, in your judgment, makes it impracticable to
     market the Securities on the terms and in the manner contemplated in the
     Prospectus.

          (e) You shall have received on the Closing Date an opinion (reasonably
     satisfactory to you and counsel for the Underwriters), dated the Closing
     Date, of the General Counsel of the Company, in form and substance
     satisfactory to you, to the effect set forth in Annex I hereto.

     substance satisfactory to you, to the effect set forth in Annex II hereto.
     The opinion of Haynes and Boone, LLP described in this Section 8(g) shall
     be rendered to you at the request of the Company and shall so state
     therein.

          (g) You shall have received on the Closing Date an opinion (reasonably
     satisfactory to you and counsel for the Underwriters), dated the Closing

     set forth in Annex III hereto.

                                       12

 
          (h) You shall have received on the Closing Date an opinion (reasonably
     satisfactory to you and counsel for the Underwriters), dated the Closing
     Date, of Fennemore Craig, special Arizona counsel for the Company, in form
     and substance satisfactory to you, to the effect set forth in Annex IV
     hereto. The opinion of Fennemore Craig described in this Section 8(h) shall
     be rendered to you at the request of the Company and shall so state
     therein.
    
          (i) You shall have received on the Closing Date a favorable opinion,
     dated the Closing Date, of Milbank, Tweed, Hadley & McCloy, counsel for the
     Underwriters, in form and substance satisfactory to you, to the effect set
     forth in Annex V hereto, and the Company shall have furnished to such
     counsel such documents as they request for the purpose of enabling them to
     pass upon such matters.     

          (j) You shall have received on the Closing Date letters, dated the
     Closing Date, in form and substance satisfactory to you, from Arthur
     Andersen LLP and KPMG Peat Marwick, independent public accountants,
     containing the information and statements of the type ordinarily included
     in accountants' "comfort letters" to Underwriters with respect to the
     financial statements and certain financial information contained in or
     incorporated by reference into the Registration Statement and the
     Prospectus.

          (k) The Underwriters shall have received a counterpart, conformed as
     executed, of the Indenture which shall have been entered into by the
     Company and the Trustee.

          (l) The Company shall not have failed on or prior to the Closing Date
     to perform or comply with any of the agreements herein contained and
     required to be performed or complied with by the Company on or prior to the
     Closing Date.

          (m) Subsequent to the execution and delivery of this Agreement and as
     of the Closing Date, (i) there shall not have occurred any downgrading,
     suspension or withdrawal of, nor any notice have been given of any
     potential or intended down grading, suspension or withdrawal of, or of any
     review (or of any potential or intended review) for a possible change that
     does not indicate the direction of the possible change in, any rating of
     the Company or any securities of the Company (including, without
     limitation, the placing of any of the foregoing ratings on credit watch
     with negative or developing implications or under review with an uncertain
     direction ) by any "nationally recognized statistical rating organization"
     as such term is defined for purposes of Rule 436(g)(2) under the Act and
     (ii) there shall not have occurred any change, nor shall any notice have
     been given of any potential or intended change, in the outlook for any
     rating of the Company or any securities of the Company by any such rating
     organization.

          Section 9.  Effectiveness of Agreement and Termination. This Agreement
shall become effective upon the later of (i) execution and delivery of this
Agreement by the parties hereto and (ii) when notification of the effectiveness
of the Registration Statement has been released by the Commission.

          This Agreement may be terminated at any time on or prior to the
Closing Date by you by written notice to the Company if any of the following has
occurred: (i) since the respective dates as of which information is given in the
Registration Statement and the Prospectus, any adverse change or development
involving a prospective adverse change in the condition, financial or otherwise,
of the Company or any of its Subsidiaries or the earnings, affairs or business
prospects of the Company or any of its Subsidiaries, whether or not arising in
the ordinary course of business, which would, in your judgment, make it
impracticable to market the Securities on the terms and in the manner
contemplated in the Prospectus, (ii) any outbreak or escalation of hostilities
or other national or international calamity or crisis or change in economic
conditions or in the financial markets of the United States or elsewhere that,
in your judgment, is material and adverse and would, in your judgment, make it
impracticable to market the Securities on the terms and in the manner
contemplated in the Prospectus, (iii) the suspension or material limitation of
trading in securities on the New York Stock Exchange, the American Stock

                                       13

 
Exchange or the Nasdaq National Market System or limitation on prices for
securities on any such exchange or National Market System, (iv) the enactment,
publication, decree or other promulgation of any federal or state statute,
regulation, rule or order of any court or other governmental authority which in
your opinion materially and adversely affects, or will result in an material
adverse effect on the business, financial condition or results of operations of
the Company and its Subsidiaries, taken as a whole, (v) the declaration of a
banking moratorium by either federal or New York State authorities, (vi) the
taking of any action by any federal, state or local government or agency in
respect of its monetary or fiscal affairs which in your opinion has a material
adverse effect on the financial markets in the United States or (vii) the
suspension or (vii) the suspension or material limitation of trading in
securities of TNP Enterprises, Inc. ("TNPE") on the New York Stock Exchange or

          If on the Closing Date any one or more of the Underwriters shall fail
or refuse to purchase the Securities which it or they have agreed to purchase
hereunder on such date and the aggregate principal amount of Securities which
such defaulting Underwriter or Underwriters agreed but failed or refused to
purchase is not more than one-tenth of the aggregate principal amount of
Securities to be purchased on such date by all Underwriters, each non-defaulting
Underwriter shall be obligated severally, in the proportion which the principal
amount of Securities set forth opposite its name in Schedule I bears to the
aggregate principal amount of Securities which all the non-defaulting
Underwriters have agreed to purchase, or in such other proportion as you may
specify, to purchase the Securities which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date, provided
that in no event shall the aggregate principal amount of Securities which any
Underwriter has agreed to purchase pursuant to Section 2 hereof be increased
pursuant to this Section 9 by an amount in excess of one-ninth of such principal
amount of Securities without the written consent of such Underwriter. If on the
Closing Date any Underwriter or Underwriters shall fail or refuse to purchase
Securities and the aggregate principal amount of Securities with respect to
which such default occurs is more than one-tenth of the total principal amount
of Securities to be purchased by all Underwriters and arrangements satisfactory
to the non-defaulting Underwriters and the Company for purchase of such
Securities are not made within 36 hours after such default, this Agreement will
terminate without liability on the part of the non-defaulting Underwriters and
the Company. In any such case which does not result in termination of this
Agreement, either you or the Company shall have the right to postpone the
Closing Date, but in no event for longer than seven days, in order that the
required changes, if any, in the Registration Statement and the Prospectus or
any other documents or arrangements may be effected. Any action taken under this
paragraph shall not relieve any defaulting Underwriter from liability in respect
of any default of any such Underwriter under this Agreement.
    
          Section 10. Miscellaneous. Notices given pursuant to any provision of
this Agreement shall be addressed as follows: (i) if to the Company, to Texas-
New Mexico Power Company, 4100 International Plaza, P.O. Box 2943, Fort Worth,
TX 76113, Attention: Michael B. Blanchard, (ii) if to any Underwriter, c/o
                          or (iii) in any case, to such other address as the
person to be notified may have requested in writing.     

          The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company and the several Underwriters set
forth in or made pursuant to this Agreement shall remain operative and in full
force and effect, and will survive delivery of and payment for the Securities,
regardless of (i) any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the officers or directors of any
Underwriter, any person controlling any Underwriter, the Company, the officers
or directors of the Company or any person controlling the Company, (ii)
acceptance of the Securities and payment for them hereunder and (iii)
termination of this Agreement.

          If this Agreement is terminated by the Underwriters because of any
failure or refusal on the part of the Company to comply with the terms or to
fulfill any of the conditions of this Agreement, the Company agrees to reimburse
the several Underwriters for all out-of-pocket expenses (including the fees and
disbursements of counsel) reasonably incurred by them.

                                       14

 
          Except as otherwise provided, this Agreement has been and is made
solely for the benefit of and shall be binding upon the Company, the
Underwriters, the Underwriters' directors and officers, any controlling persons
referred to herein, the Company's directors and the Company's officers who sign
the Registration Statement and their respective successors and assigns, all as
and to the extent provided in this Agreement, and no other person shall acquire
or have any right under or by virtue of this Agreement. The term "successors and
assigns" shall not include a purchaser of any of the Securities from any of the
several Underwriters merely because of such purchase.

          This Agreement shall be governed and construed in accordance with the
laws of the State of New York.

          This Agreement may be signed in various counterparts which together
shall constitute one and the same instrument.

                                       15

 
          If the foregoing correctly sets forth the understanding among each of
the Company and the Underwriters, please so indicate in the space provided below
for the purpose, whereupon this letter and the Underwriters' acceptance shall
constitute a binding agreement among the Company and the Underwriters,
severally.

                                        Very truly yours,

                                        TEXAS-NEW MEXICO POWER COMPANY
