Item 5.   Other Events

         On May 24, 1999, TNP Enterprises, Inc., a Texas corporation ("TNP"), SW
Acquisition , L.P., a limited partnership  organized and existing under the laws
of Texas ("Parent"),  and ST Acquisition Corp., a Texas corporation wholly owned
by Parent ("Sub"), entered into an Agreement and Plan of Merger, dated as of May
24, 1999  (the"Merger  Agreement"),  which provides for a merger of TNP with and
into ST Corp.,  with TNP being the surviving  corporation (the "Merger").  Under
the terms of the Merger  Agreement,  each issued and outstanding share of Common
Stock,  no par value, of TNP will be canceled and converted  automatically  into
the right to receive $44.00 in cash (the "Merger Consideration").

         On August 9, 1999, TNP, Parent and Sub entered into the First Amendment
to the Merger Agreement (the "Amendment").  The Amendment provides,  among other
things,  that the Texas-New  Mexico Power Company Thrift Plan for Employees will
not be terminated but will be amended  effective as of the effective time of the
Merger to prohibit the issuance by TNP or any of its subsidiaries of any capital
stock of TNP or its subsidiaries.

         The  total  financing  for the  Merger  (including  related  costs  and
expenses) will be approximately  $1.068 billion.  Of this amount,  approximately
$590  million  will  be  required  to pay  the  Merger  Consideration  and up to
approximately $428 million may be required to refinance certain  indebtedness of
TNP's wholly-owned subsidiary, Texas-New Mexico Power Company ("TNMP"), that may
become due or that TNMP may be required to  repurchase as a result of the change
of control of TNP  contemplated  by the Merger.  Sub intends to obtain all funds
needed for the  consummation  of the Merger through capital  contributions  from
Parent and through borrowing under credit facilities more fully described below.
Parent and Sub have received  commitment letters with respect to such facilities
(the  "Commitment  Letters")  to  provide  funding  on the terms and  conditions
specified  therein.  Because  financing  is a  condition  to  the  Merger,  each
condition  to  funding  set forth in the  Commitment  Letters is  effectively  a
condition  to Parent's  and Sub's  obligations  to effect the Merger.  There are
numerous conditions to these financings, and there can be no assurance that such
conditions  will be  satisfied  or waived or that such  financings  will be made
available to Parent or Sub, as the case may be.

         When they  executed the Merger  Agreement,  Parent and Sub delivered to
TNP  executed  copies  of  (1)   subscription   agreements   (the   "Partnership
Subscription  Agreements") from the general partner of Parent, Canadian Imperial
Bank  of  Commerce  (collectively  with  its  affiliates,   "CIBC"),   Caravelle
Investment  Fund,  L.L.C.,  an  investment  fund managed by CIBC  ("Caravelle"),
Continental  Casualty  Company,  an  indirect  subsidiary  of Loews  Corporation
("CCC"),  and Laurel Hill Capital Partners,  LLC ("Laurel Hill")  (collectively,
the  "Partnership  Investors")  to commit the equity  financing in the amount of
$100 million to provide Parent and Sub with a portion of the funds  necessary to
consummate  the  transactions  contemplated  by  the  Merger  Agreement,  (2)  a
commitment  letter (the "Preferred Stock Bridge  Commitment  Letter") from CIBC,
The Chase  Manhattan Bank ("Chase"),  CCC and Laurel Hill (the "Preferred  Stock
Investors" and, together with the Partnership Investors, the "Equity Investors")
to commit preferred equity financing in an additional  amount of $100 million to
provide  Parent and Sub with a portion of the funds  necessary to consummate the
transactions  contemplated by the Merger Agreement,  (3) commitment letters from
CIBC,  Chase and Chase  Securities,  Inc.  ("CSI") to commit debt  financing (as
amended, the "Debt Financing") in an amount up to $868 million to provide Parent
and Sub with all  remaining  funds  necessary  to  consummate  the  transactions
contemplated by the Merger Agreement. The Debt Financing would consist of:

                  borrowings  by  Sub  of  $275  million  either  from  (1)  the
                  issuance by Sub of "high yield" Senior  Subordinated  Notes to
                  be marketed  through a public offering or a private  placement
                  to certain  institutional  investors with terms and conditions
                  consistent with then current market conditions or (2) CIBC and
                  Chase (the  "Senior  Subordinated  Lenders")  on the terms set
                  forth in a commitment letter (the "Senior  Subordinated Bridge
                  Loan Commitment Letter");

                  borrowings  by  Sub of $165 million  from CIBC,  Chase and CSI
                  (the  "Senior  Debt  Lenders")  on the  terms  set  forth in a
                  commitment letter (the "Senior Debt Commitment Letter"); and

                  borrowings of up to $428 million by  TNMP from CIBC, Chase and
                  CSI (the  "Backstop  Lenders"),  on the  terms  set forth in a
                  commitment  letter  (the  "Backstop   Commitment  Letter")  to
                  refinance  any debt of TNMP that may  become  due or that TNMP
                  may be  required  to  repurchase  as a result of the change of
                  control of TNP contemplated by the merger.

         The Preferred Stock Bridge Commitment Letter and the Commitment Letters
for the Debt  Financing  expire in February  2000.  To the extent  necessary and
subject to certain conditions contained in the Merger Agreement, Parent will use
its best  efforts to extend  these  Commitment  Letters  for an  additional  six
months. However, there can be no assurance that the Merger can be consummated by
February  2000 or that these  Commitment  Letters  will be extended  beyond such
date.

         On July 9, 1999, the Senior  Subordinated Bridge Loan Commitment Letter
was amended to remove a requirement  concerning the use of proceeds from certain
sales of securities.  The removed provision  required  generally that Parent use
proceeds of sales of debt or equity  securities by the Parent's  subsidiaries to
prepay outstanding loans under the Bridge Loan Commitment  Letter,  plus accrued
interest and any other amounts payable thereunder.

         On July 13,  1999,  the Senior  Debt  Commitment  Letter was amended to
modify a requirement concerning mandatory prepayments and commitment reductions.
Under  the  amendment,  Sub will be  generally  required  to use 100% of the net
proceeds of sales or other  dispositions of assets by Sub or its subsidiaries to
prepay loans provided under the Senior Debt Commitment Letter.  This requirement
is subject  to  certain  exceptions  and  limitations.  It does not apply to net
proceeds from sales in the ordinary course of business of inventory, receivables
or obsolete or worn-out  property,  or in certain  other  customary  situations.
Further, the amount of net proceeds that must be so applied shall be limited (a)
to the portion of such  proceeds  that remain  after they are first used to make
any applicable  mandatory  prepayments or redemptions  and (b) to an amount that
can be paid  as a  dividend  by the  subsidiary  to Sub  (after  receipt  of any
required  governmental  approvals).  Sub has  agreed to use its best  efforts to
cause such a dividend to be so paid.

         On July 21, 1999, the Senior Debt Commitment Letter was further amended
to extend the period during which definitive  documentation  must be negotiated,
executed and delivered  from within 60 days of the acceptance of the Senior Debt
Commitment  Letter to  within  120 days of the  acceptance  of the  Senior  Debt
Commitment Letter.

         Copies of the Amendment,  the Preferred Stock Bridge Commitment Letter,
the Commitment  Letters for the Debt Financing and the Partnership  Subscription
Agreements  have been filed with the  Securities  and Exchange  Commission as an
Exhibit  to this  Form 8-K.  This  summary  description  of the  Amendment,  the
Preferred Stock Bridge Commitment  Letter,  the Commitment  Letters for the Debt
Financing and the  Partnership  Subscription  Agreements  does not purport to be
complete and is qualified in its entirety by reference to such documents,  which
are incorporated by reference herein.

2 Robbins Lane

Ladies and Gentlemen:

                  The undersigned is executing this Agreement in connection with
its subscription  for a partnership  interest (an "Interest") in SW Acquisition,
L.P.  (the  "Partnership"),   a  Texas  limited  partnership.   The  undersigned
understands  that the Partnership is relying upon the accuracy and  completeness
of the  information  contained  herein in complying with its  obligations  under
federal and state securities and other applicable laws.  Capitalized  terms used
but not defined  herein have the same  meanings as in the  Agreement  of Limited
Partnership  of the  Partnership,  dated as of May 24,  1999  (the  "Partnership
Agreement"), a copy of which is attached as Exhibit A hereto.

                  The undersigned hereby irrevocably agrees with, and represents
and warrants to and for the benefit of, the Partnership and the limited partners
in the Partnership (the "Limited Partners") as follows:

         1. Subscription.

                  (a) Subject to the terms and conditions of this Agreement, the
undersigned hereby  irrevocably  subscribes for Interests in the Partnership and
agrees  to  make an  aggregate  Capital  Contribution  (the  "Aggregate  Capital
Contribution")  to the Partnership in respect thereof in the amount set forth on
the signature page hereof and agrees to pay such Aggregate Capital  Contribution
to the Partnership in accordance with the terms of the Partnership Agreement and
this  Agreement.  Upon  the  execution  of this  Agreement  and the  Partnership
Agreement,  the  undersigned  is paying to the  Partnership  an amount  equal to
 .0001% of the Aggregate Capital Contribution. At the closing of the merger under
the Merger Agreement (the "Closing"),  the undersigned  shall make an additional
Capital  Contribution  to the  Partnership  of an amount equal to 99.999% of the
Aggregate Capital Contribution,  less any Capital Contributions made pursuant to
paragraph (b) below.

                  (b) To the  extent  that,  from  time  to  time  prior  to the
Closing,  all Partners are notified  that the  Partnership  has incurred  actual
reasonable  out-of-pocket  expenses  (the  "Expenses")  in  connection  with (i)
obtaining the insurance required by Section 8.8(c) of the Partnership Agreement,
(ii)  leasing  office space for the General  Partner,  and  reasonable  overhead
expenses in connection therewith,  and (iii) payments to unrelated third parties
in connection  with  satisfying  the conditions  under the financing  agreements
entered into in connection with the Merger Agreement,  the undersigned will make
an additional  Capital  Contribution (an "Expense Capital  Contribution") to the
Partnership, within five days of such notice, in an amount equal to its pro rata
portion (based on the relative actual Capital  Contributions of all Partners) of
the Expenses,  and any such Expense Capital  Contribution shall be treated as an
advance payment of a portion of the Aggregate Capital  Contribution  required to
be paid at the Closing  pursuant to paragraph  (a);  provided that the aggregate
Capital  Contributions  required to be made by all  Partners  for such  Expenses
shall in no event exceed  $600,000;  provided further that in no event shall any
such Expense Capital  Contribution  increase the Aggregate Capital  Contribution
which the undersigned has agreed to make under this Agreement.

                  (c) The undersigned herewith tenders two signed copies of this
Agreement and an executed signature page of the Partnership Agreement.

         2. General Partner Acceptance. Upon execution of this  Agreement by the
general  partner of the  Partnership  (the "General  Partner") on behalf of this
Partnership,  this  Agreement  shall  become a  binding  agreement  between  the
Partnership and the undersigned.

         3. Other  Subscription  Agreements.  The   Partnership  has  heretofore
entered into, and expects to enter into,  separate but  substantially  identical
subscription agreements (the "Other Subscription  Agreements" and, together with
this Agreement, the "Subscription Agreements") with other purchasers (the "Other
Purchasers"),  providing  for  the  subscription  by  the  Other  Purchasers  of
Interests  for  an  aggregate   Capital   Contribution  to  the  Partnership  of
$100,000,000  (including the Capital  Contributions  subscribed for  hereunder).
This  Agreement and the Other  Subscription  Agreements are separate and several
agreements,  and the  sales of  Interests  to the  undersigned  and to the Other
Purchasers are to be separate and several sales.

         4. Representations and Warranties of the Undersigned.   The undersigned
hereby represents and warrants to the Partnership as follows:

                  (a)  Organization and  Qualification.  The undersigned is duly
         organized or formed,  validly  existing and in good standing  under the
         laws of the state of its  organization  or  formation,  except for such
         failures  to be  so  formed,  existing  and  in  good  standing  which,
         individually  or in the  aggregate,  are not  having  and  could not be
         reasonably   expected  to  have  a  material   adverse  effect  on  the
         undersigned and its subsidiaries taken as a whole.

                  (b) Authority.  The  undersigned  has the requisite  power and
         authority to enter into this Agreement and the  Partnership  Agreement,
         to perform its  obligations  hereunder and thereunder and to consummate
         the  transactions  contemplated  hereby  and  thereby.  The  execution,
         delivery  and   performance  of  this  Agreement  and  the  Partnership
         Agreement by the undersigned and the consummation by the undersigned of
         the  transactions  contemplated  hereby and thereby  have been duly and
         validly approved by all necessary  action,  and no other proceedings on
         the part of the  undersigned  are necessary to authorize the execution,
         delivery and  performance of this Agreement by the  undersigned and the
         consummation by the undersigned of the transactions contemplated hereby
         and thereby.  Each of this Agreement and the Partnership  Agreement has
         been duly and validly  executed and delivered by the  undersigned  and,
         assuming  the  due  authorization,   execution  and  delivery  of  this
         Agreement and the Partnership Agreement by the Partnership, constitutes
         a legal,  valid and binding  obligation of the undersigned  enforceable
         against the  undersigned  in  accordance  with their  terms,  except as
         enforceability    may   be   limited   by    bankruptcy,    insolvency,
         reorganization,   moratorium  or  other  similar  laws   affecting  the
         enforcement  of creditors'  rights  generally and by general  equitable
         principles  (regardless of whether such enforceability is considered in
         a proceeding in equity or at law).

                  (c)      Non-Contravention; Approvals and Consents.

                           (i) The execution and delivery of this  Agreement and
                  the  Partnership  Agreement by the undersigned do not, and the
                  performance by the  undersigned of its  obligations  hereunder
                  and  thereunder  and  the  consummation  of  the  transactions
                  contemplated  hereby  and  thereby  will not,  conflict  with,
                  result  in a  violation  or  breach  of,  constitute  (with or
                  without notice or lapse of time or both) default under, result
                  in  or  give  to  any   person   any  right  of   payment   or
                  reimbursement,   termination,  cancellation,  modification  or
                  acceleration  of, or result in the creation or  imposition  of
                  any  Lien  upon  any  of  the  assets  or  properties  of  the
                  undersigned or any of the  undersigned's  subsidiaries  under,
                  any  of  the  terms,  conditions  or  provisions  of  (1)  the
                  certificates or articles of  incorporation or bylaws (or other
                  comparable charter documents) of the undersigned or any of its
                  subsidiaries,  or (2)  subject  to the  taking of the  actions
                  described  in  paragraph  (ii) of this  Section,  (x) any laws
                  existing on the date hereof or orders of any  Governmental  or

                  its  subsidiaries  or  any  of  their  respective   assets  or
                  properties,  or (y) any Contracts to which the  undersigned or
                  any of its subsidiaries is a party or by which the undersigned
                  or any of its subsidiaries or any of their  respective  assets
                  or properties is bound,  excluding from the foregoing  clauses
                  (x)  and  (y)  conflicts,   violations,   breaches,  defaults,
                  terminations,  modifications,  accelerations and creations and
                  impositions of Liens which,  individually or in the aggregate,
                  could not be  reasonably  expected to have a material  adverse
                  effect on the ability of the  undersigned  to  consummate  the
                  transactions contemplated by this Agreement.

                           (ii) Except as disclosed on Schedule 4(c) hereto,  no
                  consent,  approval or action of,  filing with or notice to any
                  Governmental  or  Regulatory  Authority  or  other  public  or
                  private third party is necessary or required  under any of the
                  terms,  conditions  or  provisions  of any law or order of any
                  Governmental or Regulatory  Authority or any Contract to which
                  the  undersigned or any of its  subsidiaries  is a party or by
                  which the  undersigned  or any of its  subsidiaries  or any of
                  their  respective  assets  or  properties  is  bound  for  the
                  execution  and delivery of this  Agreement or the  Partnership
                  Agreement  by  the   undersigned,   the   performance  by  the
                  undersigned of its obligations  hereunder or thereunder or the
                  consummation  of  the  transactions   contemplated  hereby  or
                  thereby, other than such consents, approvals, actions, filings
                  and notices  which the failure to make or obtain,  as the case
                  may  be,  individually  or in  the  aggregate,  could  not  be
                  reasonably  expected to have a material  adverse effect on the
                  ability of the  undersigned  to  consummate  the  transactions
                  contemplated by this Agreement or the Partnership Agreement.

                  (d)  Residence.  The principal  place of business  address set
         forth  on the  signature  page  hereof  is the  undersigned's  true and
         correct  principal  place of business and is the only  jurisdiction  in
         which an offer to sell the  Interests was made to the  undersigned  and
         the undersigned has no present  intention of moving its principal place
         of business to any other state or jurisdiction;

                  (e) No  Registration.  The  undersigned  understands  that the
         Interests have not been registered  under the Act, or under the laws of
         any  other  jurisdiction,  and that  except as  otherwise  contemplated
         pursuant  to  the  Partnership  Agreement,  the  Partnership  does  not
         contemplate  and is under no obligation  to so register the  Interests.
         The undersigned  understands and agrees that the Interests must be held
         indefinitely  unless they are subsequently  transferred (i) pursuant to
         an effective  registration statement under the Act and, where required,
         under the laws of other  jurisdictions or (ii) pursuant to an exemption
         from applicable  registration  requirements.  Even if such exemption is
         available,   the   undersigned   agrees   that   the   assignment   and
         transferability  of the Interests  will be governed by the  Partnership
         Agreement.  The Partnership Agreement imposes substantial  restrictions
         on assignment or transfer of Interests. The undersigned recognizes that
         there is no established trading market for the Interests and that it is
         unlikely that any public  market for the Interests  will develop for at
         least five years.  The undersigned  will not offer,  sell,  transfer or
         assign its Interest or any interest  therein in  contravention  of this
         Agreement,  the Partnership Agreement,  the Act or any state or federal
         law;

                  (f)  Purchase  for  Investment.  The  Interests  for which the
         undersigned  hereby  subscribes  are  being  acquired  solely  for  the
         undersigned's  own account for investment  and are not being  purchased
         with a view to or for resale,  distribution or other  disposition,  and
         the  undersigned  has no  present  plans  to enter  into any  contract,
         undertaking, agreement or arrangement for any such resale, distribution
         or other disposition;

                  (g)  Knowledge.  The undersigned  has  been  furnished and has
         carefully read the Partnership Agreement.  The undersigned understands,
         acknowledges and agrees that:

                           (i)      the Partnership has recently been  organized
                   and therefore has no financial or operating history;

                           (ii)     the undersigned is not entitled  to  cancel,
                   terminate or  revoke this  Agreement  or any  of  the  powers
                   conferred herein;

                           (iii)    various conflicts of interest may arise out
                   of transactions between the Partnership, the Limited Partners
                   and the General Partner and their respective Affiliates; and

                           (iv)     the Interests are  speculative  investments
                   which involve a high degree of risk.

                  (h)   Information.   The  undersigned  has  been  granted  the
         opportunity to ask questions of, and receive answers from, the sponsors
         of the  Partnership  concerning the terms and conditions of the sale of
         the Interests,  the Merger Agreement and the transactions  contemplated
         thereby, and to obtain any additional information which the undersigned
         deems  necessary  to  make  an  informed   investment   decision.   The
         undersigned has received or has had access to other documents requested
         from  the  Partnership  relating  to the  Interests  and  the  purchase
         thereof,   and  the   Partnership  has  afforded  the  undersigned  the
         opportunity to discuss the undersigned's  investment in the Partnership
         and  to ask  and  receive  answers  to any  questions  relating  to the
         investment in the Interests,  the Merger Agreement and the transactions
         contemplated thereby. The undersigned understands and has evaluated the
         risks of a purchase of the Interests;

                  (i)   Accredited Investor.  The undersigned  has read the text
         of Rule 501(a)(1) - (8) of Regulation D under the Act and confirms that
         it is an "accredited investor" as described thereby;

                  (j)      Plan Assets.

                           (i) By checking below,  the undersigned has indicated
                  whether  or not it is, or is acting on behalf  of, a  "benefit
                  plan investor",  as defined in 29 C.F.R. ss.  2510.3-101.  The
                  undersigned  acknowledges  that (A) a  benefit  plan  investor
                  includes (x) an "employee  benefit plan" within the meaning of
                  Section 3(3) of the U.S.  Employee  Retirement Income Security
                  Act of 1974, as amended ("ERISA"), whether or not such plan is
                  subject  to ERISA,  or (y) a plan or  arrangement  subject  to
                  Section 4975 of the Code or (iii) an entity which is deemed to
                  hold the assets of any such  employee  benefit  plan,  plan or
                  arrangement  described  in  (x) or (y)  above  pursuant  to 29
                  C.F.R.  ss.  2510.3-101  or  otherwise,  (B) a plan  which  is
                  maintained by a foreign  corporation,  governmental  entity or
                  church,  a Keogh plan covering no common-law  employees and an
                  individual  retirement  account  would each be a benefit  plan
                  investor for this purpose,  even though they are generally not
                  subject to ERISA and (C) a foreign or U.S. entity which is not
                  an  operating  company  and  which is not  publicly  traded or
                  registered  as an  investment  company  under  the  Investment
                  Company Act of 1940,  as amended,  and in which 25% or more of
                  the value of any class of equity  interests is held by benefit
                  plan  investors,  would be deemed to hold the assets of one or
                  more employee benefit plans pursuant to 29 C.F.R.  2510.3-101.
                  The  undersigned  further  understands  that for  purposes  of
                  determining  whether  this  25%  threshold  has  been  met  or
                  exceeded,  the value of any equity  interests held by a person
                  (other than a benefit  plan  investor)  who has  discretionary
                  authority or control with respect to the assets of the entity,
                  or any person who provides investment advice for a fee (direct
                  or indirect) with respect to such assets,  or any affiliate of
                  such a person, is disregarded:

                           ___   Yes             ___   No


                           (ii) By checking below, the undersigned has indicated
                  whether  it is, or is acting on behalf  of,  such an  employee
                  benefit plan,  plan or arrangement  described in the preceding
                  question,  or is an entity  deemed  to hold the  assets of any
                  such  employee  benefit  plan,  plan  or  arrangement  that is
                  subject to ERISA and/or Section 4975 of the Code"

                           ___   Yes             ___   No


                           (iii)  By  checking   below,   the   undersigned  has
                  indicated  whether it is an insurance  company using assets of
                  its general account?

                           ___    Yes            ___   No

                  If the answer to the above  question is yes,  please  indicate
                  the percentage of the general  account that is attributable to
                  benefit plan investors subject to ERISA and/or Section 4975 of
                  the Code: _______%;


                  (k)  Holding  Company  Acts and FPA. On the date  hereof,  the
         undersigned is not a "public utility company",  a "holding company",  a
         "subsidiary  company" of a "holding  company",  or an  "affiliate" of a
         "holding  company"  or of a  "subsidiary  company",  as such  terms are
         defined in the Public Utility  Holding Company Act of 1935, as amended,
         ("PUCHA") or a "public  utility" as such term is defined in the Federal
         Power Act ("FPA"); and

                  (l) Ownership of Company Common Stock.  As of the date hereof,
         except as set forth in Schedule 4(l) attached  hereto,  the undersigned
         does not,  either  individually  or as part of a group for  purposes of
         Rule 13-d  under  the  Securities  Exchange  Act of 1934,  as  amended,
         beneficially  own any shares of Company Common Stock (as defined in the
         Merger Agreement).

         5.     Conditions to Closing.  The undersigned's obligation to purchase
    and deliver the Capital Contribution for the  Interest  to  be sold  by  the
    Partnership at the Closing is subject to the fulfillment on or prior to  the
    Closing of the following conditions:

                  (i)  Merger Agreement. As of the Closing all conditions to the
         consummation of the  transactions  contemplated by the Merger Agreement
         shall  have  satisfied  or waived and the  closing of the  transactions
         contemplated by the Merger  Agreement shall occur  simultaneously  with
         the payment of the Capital Contribution hereunder.

         outstanding any  rule  or  order of any court, administrative agency or
         governmental  body  which in any way restrains or prevents the carrying
         out of the transactions contemplated by this Agreement.

                (iii)  Regulatory   Consents  and   Approvals.    All  consents,

         their  obligations under this Agreement and the Merger Agreement and to
         consummate the transactions  contemplated hereby and thereby shall have
         been  duly  obtained,  made or given  and  shall be in full  force  and
         effect,  and all terminations or expirations of waiting periods imposed
         by  any  Governmental  or  Regulatory   Authority   necessary  for  the
         consummation  of  the  transaction   contemplated  by  this  Agreement,
         including under the  Hart-Scott-Rodino  Antitrust  Improvements  Act of
         1976, as amended and the rules and regulations  promulgated thereunder,
         shall have occurred.

    arising out of a breach of any representation or warranty of the undersigned
    contained in any document  furnished by the  undersigned in  connection with
    the offering and sale of the Interests, including,  without limitation, this
    Agreement,  or  failure  by  the  undersigned to comply with any covenant or
    agreement made by the undersigned herein or in any  other document furnished
    by  the  undersigned  to  any  of  the  foregoing  in  connection  with this
    transaction.

         8.     Survival;   Binding   Effect.    All   covenants,    agreements,
     representations and warranties made herein shall survive the execution  and
     delivery of this Agreement  and  delivery  of  the  Interests  and  payment

     made  by  the undersigned or on the undersigned's behalf, shall continue in
     full force and effect.  Whenever  in  this  Agreement  any  of  the parties
     hereto is referred to, such  reference  shall  be  deemed  to  include  the
     successors and assigns of such  party;  and  all  covenants,  promises  and
     agreements in this Agreement by or on behalf of the Partnership, or  by  or
     on  behalf  of  the undersigned, shall bind and inure to the benefit of the
     successors and assigns of such parties hereto.

     employees, agents or other representatives or affiliates).  Notwithstanding
     the foregoing, no such termination shall  affect  the  obligations  of  the
     undersigned pursuant to Section 1(b) and Section 7, which shall survive any

     Partnership a list of  addresses of all Partners  of the Partnership, which
     list shall be promptly furnished to the undersigned.

         11. Complete Agreement;  Counterparts.  This Agreement  constitutes the
     entire  agreement and supersedes all other  agreements and  understandings,

     constitute one and the same instrument.

     obligation hereunder may be assigned by any party hereto and any attempt to

     benefit   of and  shall be  enforceable by  the  parties  hereto and  their
     respective successors and assigns.

     provision of this Agreement  must be  in writing,  designated  as such, and
     signed by the party against whom enforcement of that waiver is sought.  The
     waiver by a party of a  breach of any provision of this Agreement shall not
     operate  or be construed  as a waiver  of any  subsequent  or other  breach
     thereof.

         14. Governing Law.  This Agreement  shall be governed by and  construed
     and enforced in accordance with the laws of the State of New York.

Ladies and Gentlemen:

                  The undersigned is executing this Agreement in connection with
its  subscription  for a limited  partnership  interest  (an  "Interest")  in SW
Acquisition GP, L.P. (the  "Partnership"),  a Texas limited partnership in which
SW I Acquisition, L.P., a Texas limited partnership, is the general partner (the
"General  Partner").  The undersigned  understands  that the Partnership and the
General  Partner  are  relying  upon  the  accuracy  and   completeness  of  the
information  contained herein in complying with their  obligations under federal
and state securities and other applicable laws.  Capitalized  terms used but not
defined herein have the same meanings as in the Agreement of Limited Partnership
of the Partnership,  dated as of May 24, 1999 (the "Partnership  Agreement"),  a
copy of which is attached as Exhibit A hereto.

                  The undersigned hereby irrevocably agrees with, and represents
and warrants to and for the benefit of, the Partnership, the General Partner and
the limited partners in the Partnership (the "Limited Partners") as follows:

         1.       Subscription.

                  (a) Subject to the terms and conditions of this Agreement, the
undersigned hereby  irrevocably  subscribes for Interests in the Partnership and
agrees  to  make an  aggregate  Capital  Contribution  (the  "Aggregate  Capital
Contribution")  to the Partnership in respect thereof in the amount set forth on
the signature page hereof and agrees (i) to become a Limited Partner and (ii) to
pay such Aggregate  Capital  Contributions to the Partnership in accordance with
the terms of the Partnership Agreement and this Agreement. Upon the execution of
this Agreement and the Partnership  Agreement,  the undersigned is paying to the
Partnership an amount equal to .0001% of the Aggregate Capital Contribution.  At
the  closing  of the merger  under the merger  agreement  (the  "Closing"),  the
undersigned shall make an additional Capital  Contribution to the Partnership of
an amount  equal to  99.999% of the  Aggregate  Capital  Contribution,  less any
Capital Contributions made pursuant to paragraph (b) below.

                  (b) To the  extent  that,  from  time  to  time  prior  to the
Closing,  the General Partner notifies the undersigned,  together with all other
Partners,  that the  Partnership has incurred  actual  reasonable  out-of-pocket
expenses  (the  "Expenses"),  in  connection  with (i)  obtaining  the insurance
required by Section  8.8(c) of the  Partnership  Agreement,  (ii) leasing office
space for the General Partner,  and reasonable  overhead  expenses in connection
therewith,  and (iii)  payments to unrelated  third parties in  connection  with
satisfying  the  conditions  under  the  financing  agreements  entered  into in
connection with the Merger  Agreement,  the undersigned  will make an additional
Capital  Contribution  (an "Expense Capital  Contribution")  to the Partnership,
within  five days of such  notice,  in an amount  equal to its pro rata  portion
(based on the relative  actual  Capital  Contributions  of all  Partners) of the
Expenses,  and any such  Expense  Capital  Contribution  shall be  treated as an
advance payment of a portion of the Aggregate Capital  Contribution  required to
be paid at the Closing  pursuant to paragraph  (a);  provided that the aggregate
Capital  Contributions  required to be made by all  Partners  for such  Expenses
shall in no event exceed  $600,000;  provided further that in no event shall any
such Expense Capital  Contribution  increase the Aggregate Capital  Contribution
which the undersigned has agreed to make under this Agreement.

                  (c) The undersigned herewith tenders two signed copies of this
Agreement and an executed signature page of the Partnership Agreement.

         2. General Partner Acceptance. Upon acceptance of this Agreement by the
General  Partner,  this Agreement shall become a binding  agreement  between the
Partnership  and the  undersigned  and the  General  Partner  shall  deliver one
original  fully executed copy of this Agreement and a fully executed copy of the
Partnership Agreement to the undersigned.

         3.  Other  Subscription  Agreements.  The  Partnership  has  heretofore
entered into, and expects to enter into,  separate but  substantially  identical
subscription agreements (the "Other Subscription  Agreements" and, together with
this Agreement, the "Subscription Agreements") with other purchasers (the "Other
Purchasers"),  providing  for  the  subscription  by  the  Other  Purchasers  of
Interests  for  an  aggregate   Capital   Contribution  to  the  Partnership  of
$100,000,000  (including the Capital  Contributions  subscribed for  hereunder).
This  Agreement and the Other  Subscription  Agreements are separate and several
agreements,  and the  sales of  Interests  to the  undersigned  and to the Other
Purchasers are to be separate and several sales.

         4.  Representations  and  Warranties  of the  General  Partner  and the
Partnership.  The  General  Partner and the  Partnership  hereby  represent  and
warrant to the undersigned that the following statements are true and correct as
of the date  hereof  (unless  another  date is  specified)  with  respect to the
General Partner and the Partnership, as applicable:

                  (a)  Organization and  Qualification.  Each of the Partnership
         and the General  Partner is duly formed,  validly  existing and in good
         standing  under the laws of the  State of Texas and has full  power and
         authority  to conduct its  business as and to the extent now  conducted
         and to own,  use and lease its assets and  properties,  except for such
         failures to be so formed, existing and in good standing or to have such
         power and authority  which,  individually or in the aggregate,  are not
         having and could not be reasonably  expected to have a material adverse
         effect (as defined in the Merger  Agreement) on the General  Partner or
         on the Partnership and its subsidiaries  taken as a whole.  Each of the
         Partnership  and the General  Partner was formed solely for the purpose
         of  engaging  in  the  transactions  contemplated  by  the  Partnership
         Agreement  and  Merger  Agreement,  has  engaged  in no other  business
         activities  and has  conducted  its  operations  only  as  contemplated
         thereby.

                  (b) Authority. Each of the Partnership and the General Partner
         (in its  capacity  as such) has the  requisite  partnership,  power and
         authority to execute this Agreement,  the Partnership Agreement and the
         Merger Agreement,  to perform its obligations  hereunder and thereunder
         and to consummate  the  transactions  contemplated  hereby and thereby.
         Except as set forth in the Merger  Agreement,  the execution,  delivery
         and  performance of this Agreement,  the Partnership  Agreement and the
         Merger Agreement by each of the Partnership and the General Partner (in
         its capacity as such) and the  consummation  by each of the Partnership
         and the General  Partner of the  transactions  contemplated  hereby and
         thereby  have  been  duly  and  validly   approved  by  all   necessary
         partnership  action and by the  General  Partner  (in its  capacity  as
         such),  and no other  proceedings on the part of the Partnership or the
         General Partner are necessary to authorize the execution,  delivery and
         performance of this Agreement,  the Partnership Agreement or the Merger
         Agreement  by  the   Partnership   and  the  General  Partner  and  the
         consummation  by  the  Partnership  and  the  General  Partner  of  the
         transactions  contemplated hereby and thereby.  Each of this Agreement,
         the  Partnership  Agreement and the Merger  Agreement has been duly and
         validly  executed  and  delivered  by each of the  Partnership  and the
         General Partner (in its capacity as such), as applicable, and, assuming
         the due  authorization,  execution  and  delivery  thereof by the other
         parties thereto,  constitutes a legal,  valid and binding obligation of
         each of the  Partnership and the General  Partner  enforceable  against
         each of the  Partnership and the General Partner in accordance with its
         terms,   except  as  enforceability   may  be  limited  by  bankruptcy,
         insolvency, reorganization,  moratorium or other similar laws affecting
         the enforcement of creditors' rights generally and by general equitable
         principles  (regardless of whether such enforceability is considered in
         a proceeding in equity or at law).

                  (c)   Non-Contravention;   Approvals  and  Consents.  (i)  The
         execution and delivery of this Agreement, the Partnership Agreement and
         the Merger Agreement by each of the Partnership and the General Partner
         (in its  capacity as such) do not, and the  performance  by each of the
         Partnership  and the General  Partner (in its  capacity as such) of its
         obligations  hereunder  and  thereunder  and  the  consummation  of the
         transactions  contemplated  hereby and thereby will not, conflict with,
         result in a violation or breach of,  constitute (with or without notice
         or lapse  of time or  both)  default  under,  result  in or give to any
         person   any   right  of   payment   or   reimbursement,   termination,
         cancellation,  modification  or  acceleration  of,  or  result  in  the
         creation or imposition of any Lien (as defined in the Merger Agreement)
         upon any of the assets or properties  of the General  Partner or of the
         Partnership or any of the Partnership's  subsidiaries under, any of the
         terms,  conditions or provisions of (1) the certificate of formation of
         the Partnership or the General Partner or the  certificates or articles
         of incorporation or bylaws (or other comparable  charter  documents) of
         any of the Partnership's subsidiaries,  or (2) subject to the taking of
         the actions  described in paragraph (ii) of this Section,  (x) any laws
         existing on the date hereof or orders of any Governmental or Regulatory
         Authority  (as  defined  in the  Merger  Agreement)  applicable  to the
         Partnership or any of the  Partnership's  subsidiaries  or any of their
         respective  assets or  properties,  or (y) any  Contracts  to which the
         General  Partner  or  the  Partnership  or  any  of  the  Partnership's
         subsidiaries  is a  party  or by  which  the  General  Partner  or  the
         Partnership  or  any of  Partnership's  subsidiaries  or  any of  their
         respective assets or properties is bound,  excluding from the foregoing
         clauses  (x)  and  (y)  conflicts,   violations,   breaches,  defaults,
         terminations,   modifications,    accelerations   and   creations   and
         impositions of Liens which, individually or in the aggregate, could not
         be reasonably expected to have a material adverse effect on the ability
         of  the   Partnership   and  the  General  Partner  to  consummate  the
         transactions contemplated by this Agreement or the Merger Agreement.

                  (ii) Except for the approvals  required in connection with the
         Merger as described in the Merger  Agreement,  no consent,  approval or
         action of,  filing  with or notice to any  Governmental  or  Regulatory
         Authority  or other  public or  private  third  party is  necessary  or
         required under any of the terms, conditions or provisions of any law or
         order of any  Governmental  or Regulatory  Authority or any Contract to
         which the General  Partner or the Partnership or any of the Partnership
         subsidiaries  is a  party  or by  which  the  General  Partner  or  the
         Partnership or any of the  Partnership's  subsidiaries  or any of their
         respective assets or properties is bound for the execution and delivery
         of this  Agreement  or the  Merger  Agreement  by  each of the  General
         Partner and the  Partnership,  the  performance  by each of the General

         or  the  consummation  of  the  transactions  contemplated  hereby  and
         thereby,  other than such  consents,  approvals,  actions,  filings and
         notices  which  the  failure  to make or  obtain,  as the  case may be,
         individually or in the aggregate,  could not be reasonably  expected to
         have a material  adverse  effect on the ability of the General  Partner
         and the Partnership to consummate the transactions contemplated by this
         Agreement, the Partnership Agreement or the Merger Agreement.

                  (d)  Legal   Proceedings.   There  are  no   actions,   suits,
         arbitrations or proceedings pending or, to the knowledge of the General
         Partner  or  the  Partnership,   threatened  against,  relating  to  or
         affecting,  nor  to  the  knowledge  of  the  General  Partner  or  the
         Partnership  are there any  Governmental  or  Regulatory  Authority (as
         defined in the Merger  Agreement)  investigations  or audits pending or
         threatened against, relating to or affecting, the Partnership or any of
         its  subsidiaries  or any of their  respective  assets  and  properties
         which,  individually or in the aggregate,  could be reasonably expected
         to have a material  adverse effect on the ability of the Partnership to
         consummate  the  transactions   contemplated  by  this  Agreement,  the
         Partnership  Agreement  or  the  Merger  Agreement,   and  neither  the
         Partnership nor any of its  subsidiaries is subject to any order of any
         Governmental  or Regulatory  Authority  which,  individually  or in the
         aggregate,  could be  reasonably  expected  to have a material  adverse
         effect on the ability of the Partnership to consummate the transactions
         contemplated by this Agreement, the Partnership Agreement or the Merger
         Agreement.

                  (e)  Offer of  Interests.  None of the  General  Partner,  the
         Partnership or any agent acting on behalf of the General Partner or the
         Partnership  has,  directly or  indirectly,  offered the  Interests  or
         solicited  an offer to acquire the  Interests  from any person so as to
         require  registration of the issuance and sale of the Interests sold to
         the undersigned or the Other Purchasers under the provisions of Section
         5 of the Securities  Act of 1933, as amended (the "Act").  Assuming the
         representations and warranties of the undersigned  contained herein are
         true and correct,  the sale of the  Interests  under this  Agreement is
         exempt from the  registration and prospectus  delivery  requirements of
         the Act. No form of general  solicitation  or general  advertising  was
         used by the Partnership or its  representatives  in connection with the
         offer or sale of the Interests hereunder.

                  (f) Capitalization. On the date hereof, after giving effect to
         the Initial Capital  Contributions  of all  subscribers,  the aggregate
         capital of the Partnership is $1,000.  After giving effect to the Other
         Subscription  Agreements and the transactions  contemplated hereby, the

         hereby will be validly issued,  fully paid and nonassessable  and, when
         delivered by the  Partnership  on the Closing  Date,  shall be free and
         clear  of  all  liens,  claims,  options,  charges  or  other  security
         interests or encumbrances.

                  (g) Holding Company Regulation. The Partnership is not, and as
         a result of the consummation of the  transactions  contemplated by this
         Agreement and the Merger Agreement,  is not reasonably  expected to be,
         and, upon  consummation  of the Merger,  the Surviving  Corporation (as
         defined in the  Merger  Agreement)  is not  reasonably  expected  to be
         subject  to  regulation  (i) as a  registered  public  utility  holding
         company under Public  Utility  Holding  Company Act of 1935, as amended
         ("PUHCA"),  (ii) as a public utility  holding company under (x) the New
         Mexico Public Utility Act (other than under Section  62-6-12  thereof),
         or (y) the Texas Public  Utility Act or (iii) as a public utility under
         the Federal Power Act (the "FPA").

         5.       Representations  and  Warranties  of   the  Undersigned.   The
undersigned hereby represents and  warrants  to  the  General  Partner and  the
Partnership as follows:

                  (a)  Organization and  Qualification.  The undersigned is duly

         individually  or in the  aggregate,  are not  having  and  could not be
         reasonably   expected  to  have  a  material   adverse  effect  on  the
         undersigned and its subsidiaries taken as a whole.

         authority to enter into this Agreement and the  Partnership  Agreement,
         to perform its  obligations  hereunder and thereunder and to consummate

         delivery and  performance of this Agreement by the  undersigned and the
         consummation by the undersigned of the transactions contemplated hereby

         undersigned in accordance  with their terms,  except as  enforceability
         may be limited by bankruptcy, insolvency, reorganization, moratorium or
         other similar laws  affecting  the  enforcement  of  creditors'  rights
         generally and by general  equitable  principles  (regardless of whether
         such enforceability is considered in a proceeding in equity or at law).

                  (c)      Non-Contravention; Approvals and Consents.

                  (x)  and  (y)  conflicts,   violations,   breaches,  defaults,
                  terminations,  modifications,  accelerations and creations and
                  impositions of Liens which,  individually or in the aggregate,
                  could not be  reasonably  expected to have a material  adverse
                  effect on the ability of the  undersigned  to  consummate  the
                  transactions contemplated by this Agreement.

                           (ii) Except as disclosed on Schedule 5(c) hereto,  no
                  consent,  approval or action of,  filing with or notice to any
                  Governmental  or  Regulatory  Authority  or  other  public  or
                  private third party is necessary or required  under any of the
                  terms,  conditions  or  provisions  of any law or order of any
                  Governmental or Regulatory  Authority or any Contract to which
                  the  undersigned or any of its  subsidiaries  is a party or by
                  which the  undersigned  or any of its  subsidiaries  or any of
                  their  respective  assets  or  properties  is  bound  for  the
                  execution  and delivery of this  Agreement or the  Partnership
                  Agreement  by  the   undersigned,   the   performance  by  the
                  undersigned of its obligations  hereunder or thereunder or the
                  consummation  of  the  transactions   contemplated  hereby  or
                  thereby, other than such consents, approvals, actions, filings
                  and notices  which the failure to make or obtain,  as the case
                  may  be,  individually  or in  the  aggregate,  could  not  be
                  reasonably  expected to have a material  adverse effect on the
                  ability of the  undersigned  to  consummate  the  transactions
                  contemplated by this Agreement or the Partnership Agreement.

                  (d)  Residence.  The principal  place of business  address set
         forth  on the  signature  page  hereof  is the  undersigned's  true and
         correct  principal  place of business and is the only  jurisdiction  in
         which an offer to sell the  Interests was made to the  undersigned  and
         the undersigned has no present  intention of moving its principal place
         of business to any other state or jurisdiction;

                  (e) No  Registration.  The  undersigned  understands  that the
         Interests have not been registered  under the Act, or under the laws of
         any  other  jurisdiction,  and that  except as  otherwise  contemplated
         pursuant  to  the  Partnership  Agreement,  the  Partnership  does  not
         contemplate  and is under no obligation  to so register the  Interests.
         The undersigned  understands and agrees that the Interests must be held
         indefinitely  unless they are subsequently  transferred (i) pursuant to
         an effective  registration statement under the Act and, where required,
         under the laws of other  jurisdictions or (ii) pursuant to an exemption
         from applicable  registration  requirements.  Even if such exemption is
         available,   the   undersigned   agrees   that   the   assignment   and
         transferability  of the Interests  will be governed by the  Partnership
         Agreement.  The Partnership Agreement imposes substantial  restrictions
         on assignment or transfer of Interests. The undersigned recognizes that
         there is no established trading market for the Interests and that it is
         unlikely that any public  market for the Interests  will develop for at
         least five years.  The undersigned  will not offer,  sell,  transfer or
         assign its Interest or any interest  therein in  contravention  of this
         Agreement,  the Partnership Agreement,  the Act or any state or federal
         law;

                  (f)   Purchase for  Investment.  The  Interests  for which the
         undersigned  hereby  subscribes  are  being  acquired  solely  for  the
         undersigned's  own account for investment  and are not being  purchased
         with a view to or for resale,  distribution or other  disposition,  and
         the  undersigned  has no  present  plans  to enter  into any  contract,
         undertaking, agreement or arrangement for any such resale, distribution
         or other  disposition,  except,  in the case that the  undersigned is a
         Distributing  Partner (as defined in Section 7(c)),  as contemplated by
         Section 7(c) and permitted under the Partnership Agreement;

                  (g)   Knowledge.  The  undersigned  has been furnished and has
         carefully read the Partnership Agreement. The  undersigned understands,
         acknowledges and agrees that:

                           (i)      the Partnership has recently  been organized
                  and therefore has no financial or operating history;

                           (ii)     the undersigned is  not entitled  to cancel,
                  terminate  or  revoke  this Agreement  or  any  of the  powers
                  conferred herein;

                           (iii)    various  conflicts of interest may arise out
                  of transactions between the Partnership, the  Limited Partners
                  and the General Partner and their respective Affiliates;

                           (iv)     the  Interests  are  speculative investments
                  which involve a high degree of risk; and

                           (v)      the General Partner and its Affiliates  will
                  receive  substantial  compensation  in  connection   with  the
                  management of and investment in the Partnership;

                  (h)   Information.   The  undersigned  has  been  granted  the
         opportunity to ask questions of, and receive  answers from, the General
         Partner and the sponsors of the  Partnership  concerning  the terms and
         conditions of the sale of the Interests,  the Merger  Agreement and the
         transactions   contemplated  thereby,  and  to  obtain  any  additional
         information  which the undersigned  deems necessary to make an informed
         investment decision.  The undersigned has received or has had access to
         other  documents  requested  from  the  Partnership   relating  to  the
         Interests and the purchase  thereof,  and the  Partnership has afforded
         the undersigned the opportunity to discuss the undersigned's investment
         in the  Partnership  and to ask and  receive  answers to any  questions
         relating to the investment in the Interests,  the Merger  Agreement and
         the transactions  contemplated thereby. The undersigned understands and
         has evaluated the risks of a purchase of the Interests;

                  (i)      Accredited  Investor.   The  undersigned   has   read
         the  text of Rule 501(a)(1) - (8) of Regulation D  under  the  Act  and
         confirms that it is an "accredited investor" as described thereby;

                  (j)      Plan Assets.

                           (i) By checking below,  the undersigned has indicated
                  whether  or not it is, or is acting on behalf  of, a  "benefit
                  plan investor",  as defined in 29 C.F.R. ss.  2510.3-101.  The
                  undersigned  acknowledges  that (A) a  benefit  plan  investor
                  includes (x) an "employee  benefit plan" within the meaning of
                  Section 3(3) of the U.S.  Employee  Retirement Income Security
                  Act of 1974, as amended ("ERISA"), whether or not such plan is
                  subject  to ERISA,  or (y) a plan or  arrangement  subject  to
                  Section 4975 of the Code or (iii) an entity which is deemed to
                  hold the assets of any such  employee  benefit  plan,  plan or
                  arrangement  described  in  (x) or (y)  above  pursuant  to 29
                  C.F.R.  ss.  2510.3-101  or  otherwise,  (B) a plan  which  is
                  maintained by a foreign  corporation,  governmental  entity or
                  church,  a Keogh plan covering no common-law  employees and an
                  individual  retirement  account  would each be a benefit  plan
                  investor for this purpose,  even though they are generally not
                  subject to ERISA and (C) a foreign or U.S. entity which is not
                  an  operating  company  and  which is not  publicly  traded or
                  registered  as an  investment  company  under  the  Investment
                  Company Act of 1940,  as amended,  and in which 25% or more of
                  the value of any class of equity  interests is held by benefit
                  plan  investors,  would be deemed to hold the assets of one or
                  more employee benefit plans pursuant to 29 C.F.R.  2510.3-101.
                  The  undersigned  further  understands  that for  purposes  of
                  determining  whether  this  25%  threshold  has  been  met  or
                  exceeded,  the value of any equity  interests held by a person
                  (other than a benefit  plan  investor)  who has  discretionary
                  authority or control with respect to the assets of the entity,
                  or any person who provides investment advice for a fee (direct
                  or indirect) with respect to such assets,  or any affiliate of
                  such a person, is disregarded:

                           ___   Yes             ___   No


                           (ii) By checking below, the undersigned has indicated
                  whether  it is, or is acting on behalf  of,  such an  employee
                  benefit plan,  plan or arrangement  described in the preceding
                  question,  or is an entity  deemed  to hold the  assets of any
                  such  employee  benefit  plan,  plan  or  arrangement  that is
                  subject to ERISA and/or Section 4975 of the Code"

                           ___   Yes             ___   No


                           (iii)  By  checking   below,   the   undersigned  has
                  indicated  whether it is an insurance  company using assets of
                  its general account?

                           ___      Yes     ___      No

                  If the answer to the above  question is yes,  please  indicate
                  the percentage of the general  account that is attributable to
                  benefit plan investors subject to ERISA and/or Section 4975 of
                  the Code: _______%;

                  (k)      Holding Company.  The undersigned is  not  a  "public
         utility company", a "holding  company",  a  "subsidiary company"  of  a
         "holding company", or an "affiliate" of a  "holding  company" or  of  a
         "subsidiary company", as  such  terms  are  defined  in  the  PUHCA  or
         a  "public utility" as such term is defined in the FPA; and

                  (l) Ownership of Company Common Stock.  As of the date hereof,
         except as set forth in Schedule 5(l) attached  hereto,  the undersigned
         does not,  either  individually  or as part of a group for  purposes of
         Rule 13-d  under  the  Securities  Exchange  Act of 1934,  as  amended,

         Merger Agreement).

                  "no-action letter", and (y) thereafter use its reasonable best
                  efforts to obtain such "no-action" letter.

                  (c)      Sale of Interests.

                           (i) The  Partnership,  the  General  Partner  and the
                  undersigned  acknowledge and agree that,  notwithstanding  the
                  transfer restrictions  contained in the Partnership Agreement,
                  certain  Partners  will be  permitted  to transfer  all or any
                  portion of their respective  Interests and rights hereunder in
                  accordance with Section 9.14 of the Partnership Agreement (the
                  "Distributing Partners").  The undersigned hereby agrees that,
                  to the extent it is a Distributing  Partner, any such transfer
                  by it may only be made to a limited  number  of  institutions,
                  each of  which  is  reasonably  believed  by the  Distributing
                  Partners to be an "accredited  investor" within the meaning of
                  Rule 501(a)(1),  (2), (3) or (7) under the Act or an entity in
                  which all of the equity owners are accredited investors within
                  the meaning of Rule  501(a)(1),  (2), (3) or (7) under the Act
                  (each, an "Institutional Accredited Investor"),  and that each
                  such  Institutional  Accredited  Investor shall, to the extent
                  such transfer is completed prior to the Closing Date,  execute
                  and deliver to the  Partnership,  prior to the consummation of
                  any  transfer of rights to  subscribe  for  Interests  to such
                  Institutional  Accredited Investor,  a Subscription  Agreement
                  substantially  in the form  hereof.  In no event will any such
                  transfer  relieve the undersigned  from its obligations  under
                  this Subscription Agreement.  The undersigned acknowledges and
                  agrees that,  pursuant to the engagement letter dated the date
                  hereof between the Partnership,  on behalf of the Distributing
                  Partners,  and  CIBC  World  Markets  Corp.  (the  "Engagement
                  Letter"),  any  offering  and sale of  Interests  or rights to
                  subscribe  for  Interests  shall  be made by the  Distributing
                  Partners  in  accordance   with  this  paragraph  (c)  and  in
                  accordance  with  the  terms  of the  Engagement  Letter.  The
                  undersigned will, to the extent it is a Distributing  Partner,
                  cooperate with the  Underwriters (as defined in the Engagement
                  Letter) in accordance with Section 4 of the Engagement Letter.
                  The  Partnership  hereby  agrees not to agree to any  material
                  amendment to the  Engagement  Letter without the prior written
                  consent of the undersigned. Neither the undersigned nor any of
                  its  affiliates  has entered  into,  or will without the prior
                  written consent of the Partnership enter into, any contractual
                  arrangement  with respect to a  distribution  of the Interests
                  contrary  to  the   provisions   of  this   Agreement  or  the
                  Partnership Agreement;

                           (ii) The General  Partner shall take all such actions
                  as  shall  be  necessary  to  admit  to the  Partnership  each
                  purchaser of an Interest hereunder;  provided,  however,  that
                  notwithstanding  anything herein to the contrary,  none of the
                  Distributing  Partners  shall cause to be  completed,  and the
                  General  Partner and the  Partnership may refuse to accept and
                  register,  any  assignment,  transfer or sale pursuant to this
                  paragraph  (c) if such  assignment,  transfer  or  sale  would
                  result  in  a  breach  by  the   Partnership  of  any  of  the
                  representations  or warranties  made by the Partnership in, or
                  of any of the  covenants or  agreements to be performed by the
                  Partnership pursuant to, of the Merger Agreement.

                  (d)  Notice  and Cure.  Each of the  General  Partner  and the
         undersigned   will  promptly  notify  the  other  in  writing  of,  and
         contemporaneously  will provide the other with true and complete copies
         of any and all  information or documents  relating to, and will use all
         commercially  reasonable  efforts to cure before the Closing Date,  any
         event,  transaction or  circumstance,  occurring after the date of this
         Agreement that causes or will cause any covenant or agreement of either
         such party under this  Agreement to be breached or that renders or will
         render  untrue any  representation  or  warranty  of either  such party
         contained  in this  Agreement  as if the same were made on or as of the
         date of such event, transaction or circumstance.

                  (e) Fulfillment of Conditions. Each of the General Partner and
         the undersigned will take all  commercially  reasonable steps necessary
         or desirable and proceed  diligently  and in good faith to satisfy each
         condition to the  obligations of such party contained in this Agreement
         and will not take or fail to take any action that could  reasonably  be
         expected to result in the nonfulfillment of any such condition.

         8.       Partnership Agreement.  The undersigned agrees  to enter  into
the Partnership Agreement upon acceptance of this Subscription Agreement by  the
General Partner.

         9.  Indemnification.  The  undersigned  agrees  to  indemnify  and hold
harmless the Partnership,  the General Partner,  each other Limited Partner,  or
any officer, director or control person (within the meaning of Section 15 of the
Act) of any such entity from and against any and all loss,  damage or  liability
due to or  arising  out of a breach of any  representation  or  warranty  of the
undersigned contained in any document furnished by the undersigned in connection
with the offering and sale of the Interests, including, without limitation, this
Agreement,  or  failure  by the  undersigned  to  comply  with any  covenant  or
agreement made by the undersigned  herein or in any other document  furnished by
the undersigned to any of the foregoing in connection with this transaction.

         10.   Survival;    Binding   Effect.    All   covenants,    agreements,
representations  and  warranties  made herein shall  survive the  execution  and
delivery of this  Agreement and delivery of the  Interests and payment  therefor
and,  notwithstanding  any  investigation  heretofore  or hereafter  made by the
undersigned  or on the  undersigned's  behalf,  shall continue in full force and
effect.  Whenever in this  Agreement  any of the parties  hereto is referred to,
such  reference  shall be deemed to include the  successors  and assigns of such
party;  and all  covenants,  promises and  agreements in this Agreement by or on
behalf of the Partnership, or by or on behalf of the undersigned, shall bind and
inure to the benefit of the successors and assigns of such parties hereto.

         11.  Termination.  (a)  This  Agreement  may  be  terminated,  and  the
transactions  contemplated  hereby may be  abandoned  (i) at any time before the
Closing, by mutual written agreement of the General Partner (following action by
the  Advisory  Committee)  and the  undersigned  or (ii) at any time  before the
Closing, by the General Partner or the undersigned,  in the event that any order
or law becomes  effective  restraining,  enjoining or otherwise  prohibiting  or
making illegal the consummation of any of the transactions  contemplated by this
Agreement or the Partnership,  upon notification of the non-terminating party by
the terminating party.

                  (b) This  Agreement  shall  automatically  terminate,  with no
further  action  being  required on the part of either  party  hereto,  upon any
termination of the Merger Agreement in accordance with its terms.

                  (c) This Agreement may be terminated by the undersigned if any
occurrence  or  circumstance  results in a failure to satisfy the  conditions in
Section 6(a)(iv), (v) or (vi) hereof.

                  (d) If this Agreement is validly  terminated  pursuant to this
Section,  this Agreement will forthwith  become null and void, and there will be
no liability or obligation on the part of the undersigned or the Partnership (or
any of their respective  partners,  officers,  directors,  employees,  agents or
other  representatives or affiliates).  Notwithstanding  the foregoing,  no such
termination shall affect the obligations of the undersigned  pursuant to Section
1(b) or Section 9, which shall survive any such termination.

         12. Notices. All notices,  statements,  instructions or other documents
required to be given  hereunder  shall be in writing  and shall be given  either
personally,  by overnight courier or by facsimile,  addressed to the Partnership
at its  principal  offices  and to the  other  parties  at  their  addresses  or
facsimile numbers reflected in the records of the Partnership.  The undersigned,
by written notice given to the  Partnership  in accordance  with this Section 12
may  change the  address to which  notices,  statements,  instructions  or other
documents  are  to  be  sent  to  the  undersigned.   All  notices,  statements,
instructions  and other  documents  hereunder that are mailed shall be deemed to
have been given on the date of delivery. Whenever pursuant to this Agreement any
notice is  required to be given by the  undersigned  to any other  Partner,  the
undersigned may request from the Partnership a list of addresses of all Partners
of the Partnership, which list shall be promptly furnished to the undersigned.

         13. Complete Agreement;  Counterparts.  This Agreement  constitutes the
entire  agreement and supersedes all other agreements and  understandings,  both
written and oral,  among the parties or any of them, with respect to the subject
matter hereof.  This Agreement may be executed by any one or more of the parties
hereto in any  number of  counterparts,  each of which  shall be deemed to be an
original,  but all such counterparts shall together  constitute one and the same
instrument.

         14.  Assignment.  Neither  this  Agreement  nor any right,  interest or
obligation  hereunder  may be assigned by any party hereto and any attempt to do
so will be  void,  except  that the  undersigned  may  assign  any or all of its
rights,  interests  and  obligations  hereunder to a Permitted  Transferee  that
agrees in  writing to be bound by all of the terms,  conditions  and  provisions
contained  herein,  but no such assignment  shall relieve the undersigned of its
obligations hereunder.  Subject to the preceding sentence,  this Agreement shall
be binding upon, inure to the benefit of and shall be enforceable by the parties
hereto and their respective successors and assigns.

         15.  Amendment  and Waiver.  This  Agreement may be amended or modified
only by an instrument signed by the parties hereto. A waiver of any provision of
this Agreement  must be in writing,  designated as such, and signed by the party
against whom  enforcement  of that waiver is sought.  The waiver by a party of a
breach of any provision of this Agreement shall not operate or be construed as a
waiver of any subsequent or other breach thereof.

         16.      Governing  Law.   This  Agreement  shall  be  governed by  and
construed and enforced in accordance with the laws of the State of New York.

(the "Partnership") has formed an acquisition  subsidiary,  ST Acquisition Corp.
("Newco"),  which  intends to enter into a  transaction  pursuant to which Newco
will merge (the "Merger") with and into TNP Enterprises, Inc. ("XYZ"), a holding
company that owns Texas-New Mexico Power Company ("ABC"). In connection with the
Merger,  the  former  shareholders  of  XYZ  will  become  entitled  to  receive
approximately  $590.0  million (or $44.00 per share,  net to the seller) in cash
and the  Partnership  will  become the owner of all the  issued and  outstanding
capital stock of XYZ. We further  understand that the funding  requirements  for
the Merger  (including  related fees and expenses) will be approximately  $640.0
million and such amount,  together with ongoing working  capital needs,  will be
provided  solely  from (i) a senior  secured  term  loan  and  revolving  credit
facility  of  Newco  (the  "Credit   Facilities")   of  up  to  $165.0   million
(approximately  $25.0  million  of the  revolving  credit  portion of the Credit
Facilities to be drawn on the closing date of the Merger (the  "Closing  Date"),
(ii) a backstop  facility of ABC with aggregate  availability  of $428.0 million
(the  "Backstop  Facility"),  (iii) not less than a $100.0 million common equity
investment by the Equity  Investors in the Partnership and the investment by the
Partnership in Newco of a portion of such amount which,  together with the other
financing, is sufficient to consummate the Merger (the "Equity Financing"), (iv)
the  issuance  and sale of not less than  $100.0  million  of  preferred  equity
securities  of Newco (the  "Preferred  Equity") and (v) the issuance and sale of
Debt  Securities (as defined  below).  The Merger,  the Credit  Facilities,  the
Backstop  Facility,  the Equity Financing,  the bridge loan contemplated by this
letter,  the issuance and sale of bridge  preferred  stock  contemplated  by the
commitment  letter among CIBC,  The Chase  Manhattan  Bank ("CMB"),  Continental
Casualty  Company,  Laurel Hill Capital  Partners LLC, the Partnership and Newco
(the "Bridge  Preferred Stock") and the issuance and sale of the Preferred Stock
and  the  Debt   Securities   are  herein   collectively   referred  to  as  the
"Transaction".

                  In connection  with the  Transaction,  you have engaged one or
more investment banks reasonably  satisfactory to the Lenders (as defined below)
to sell or place senior debt securities of Newco (the "Debt Securities").

                  You have  requested  that each of CIBC and CMB  (collectively,
the  "Lenders")  commit to provide to Newco  funds in the amount of up to $137.5
million ($275.0  million in the aggregate) in the form of a senior  subordinated
increasing  rate bridge loan (the  "Bridge  Loan"),  as  described  in Section 1
hereof.

                  Accordingly,  subject to the terms and conditions set forth or
incorporated in this letter, the Lenders agree with you as follows:

                  Section 1. Bridge Loan.  The  Lenders  hereby  commit,  on  an
equal, but not joint and several, basis  subject  to  the  terms and  conditions
hereof and in the Summary Term Sheet attached hereto as Exhibit A (collectively,
the "Term Sheet"), to provide  to Newco a  senior  subordinated  increasing rate
bridge  loan on the Closing Date in the  aggregate  principal  amount of  up  to
$275.0  million. The proceeds of the Bridge Loan shall be used solely to finance
the Merger and to pay fees and expenses incurred  in connection  therewith.  The
principal terms of the Bridge Loan are summarized in the Term Sheet.

                  Unless  the  Lenders'  commitment  hereunder  shall  have been
terminated pursuant to Section 7, the Lenders or their Affiliates shall have the
exclusive right to provide the Bridge Loan or other bridge or interim  financing
required in connection with the Transaction; provided, that Continental Casualty
Company shall have the right to purchase  Bridge  Preferred Stock as provided in
the Commitment Letter relating to the Bridge Preferred Stock.

                  You hereby  represent  and covenant  that based on your review
and analysis,  (a) all  information  other than  Projections  (as defined below)
which has been or is  hereafter  made  available  to the  Lenders by you or your
representatives,  advisors or  affiliates in  connection  with the  transactions
contemplated hereby (the "Information") has been reviewed and analyzed by you in
connection  with the  performance  of your own due diligence and, to the best of
your knowledge,  is, or in the case of Information made available after the date
hereof  will be,  correct  in all  material  respects  and does not and will not
contain any untrue statement of a material fact or omit to state a material fact
known to you and  necessary to make the  statements  contained  therein,  in the
light of the  circumstances  under which such  statements  were or are made, not
misleading,  (b) to the best of your knowledge,  the consolidated EBITDA of XYZ,
ABC and their consolidated subsidiaries for the year ended December 31, 1998 was
at least $135.0 million and (c) all financial  projections  concerning  ABC, XYZ
and Newco that have been or are hereafter  made  available to the Lenders by you
or  your  representatives,   advisors  or  affiliates  in  connection  with  the
transactions  contemplated  hereby (the "Projections") have been or, in the case
of Projections  made available  after the date hereof,  will be prepared in good
faith  based  upon  reasonable   assumptions  (it  being   understood  that  the
Projections are subject to significant uncertainties and contingencies,  many of
which are  beyond  your  control  and that no  assurance  can be given that such
Projections  will be realized).  You agree to supplement the Information and the
Projections  from time to time until the termination of the Lenders'  commitment
hereunder so that the representation and warranty made in the preceding sentence
is correct as of such date. In arranging and  syndicating  the Bridge Loan,  the
Lenders will be using and relying on the  Information and the  Projections.  The
representations and covenants contained in this paragraph shall remain effective
until definitive financing agreements are executed and thereafter the disclosure
representations contained herein shall be terminated and of no further force and
effect.  For purposes of this  Agreement,  "EBITDA" means,  for any period,  the
aggregate amount of Consolidated  Net Income (as defined),  after adding thereto
interest charges,  interest income, income taxes, depreciation and amortization,
amortization  of  regulatory  assets,  amortization  or  intangibles,   non-cash
regulatory deferrals and other amortizations, extraordinary items, and any other
non-cash non-recurring items.

                  The  Lenders or their  respective  affiliates  will act as the
exclusive administrative agents, advisors and arrangers in respect of the Bridge
Loan and will, in such capacities, perform the duties and exercise the authority
customarily  performed  and  exercised  by it in such roles.  The Lenders  shall
consider your reasonable  suggestions for co-agents and co-arrangers;  provided,
however,  that you shall not (i) appoint other  agents,  co-agents or arrangers,
(ii) award any other titles or (iii) pay compensation (other than that expressly
contemplated by the Term Sheet), in connection with the Bridge Loan.

                  The Lenders shall be entitled to change the  structure  and/or
pricing of the Credit  Facilities,  the Backstop  Facility or the Bridge Loan if
they  determine  that such changes are advisable in order to ensure a successful
syndication;  provided, however, that in no event shall the amount of the Credit
Facilities,  the Bridge Loan or the  Backstop  Facility be lowered nor shall any
change in structure create the requirement for any material  regulatory approval
not envisioned at the time the Merger Agreement was executed.

                  Section  2.   Financing   Documentation.  The  making  of  the
Bridge  Loan will be governed  by  definitive   loan   and  related   agreements
and   documentation (collectively,  the "Financing  Documentation") in form  and
substance reasonably satisfactory  to the Lenders  and  to  you.  The  Financing
Documentation  shall be prepared  by Cahill  Gordon &  Reindel,  special counsel
to the Lenders. The Financing Documentation shall contain such covenants,  terms
and conditions as are  consistent  with this  letter and the Term Sheet and such
other  covenants,  terms,  conditions,  representations,  warranties,  events of
default and remedies provisions as shall be satisfactory to the Lenders and you.

                  Section 3.   Conditions.  The obligation of  the Lenders under

          of XYZ of not more than  $44.00 per share,  net to the seller in cash.
          The  Merger  Agreement  shall not have been  amended  in any  material
          respect without the Lenders' written consent,  which consent shall not
          be  unreasonably  withheld.  All  conditions  precedent  to the Merger
          contained  in the  Merger  Agreement  shall  have  been  performed  or

          (including  with  respect  to  funding)  and  in  form  and  substance
          reasonably  satisfactory  to the Lenders.  All  conditions  to funding
          thereunder  shall have been  satisfied or waived only with the consent
          of  the  Lenders,  not  to  be  unreasonably   withheld.   The  Senior
          Documentation  shall not have been amended,  without Lenders' consent,
          which consent shall not be unreasonably withheld.

               (d) Equity  Financing.  On or prior to the  Closing  Date,  Newco

          conditions of the Equity  Financing and the Bridge  Preferred Stock or
          the  Preferred  Equity  and  any  tax  sharing  arrangement  shall  be
          satisfactory to the Lenders.

               (e) No Adverse  Change or  Development,  Etc. (i) There shall not
          have occurred since the date of the most recent  financial  statements
          of XYZ a  material  adverse  effect on the rights or  remedies  of the
          Lenders,  or on the  ability of ABC,  XYZ and Newco to  perform  their
          obligations  to the  Lenders  or on the  business,  property,  assets,
          nature of assets,  liabilities,  condition  (financial or  otherwise),
          results of  operations or prospects of ABC; (ii) trading in securities

          disruption in the general  financial banking or capital markets of the
          United States which,  in each case, in the reasonable  judgment of the
          Lenders would materially and adversely affect or impair the ability to
          sell or place the Debt Securities or syndicate the Bridge Loan.

               (f)  Capital  Structure.   The  pro  forma  consolidated  capital
          structure  of  Newco,   ABC  and  XYZ,  after  giving  effect  to  the

          under the Securities Act of 1933), shall be consistent in all material
          respects  with the  Projections  and  capital  structure  contemplated
          herein.

               (g) Governmental and Third Party Approvals.  All governmental and

          clause (i) above as to which such  financial  statements are available
          and such financial  statements  shall not reflect any material adverse
          change in the  consolidated  financial  conditions  of XYZ and ABC and
          their respective subsidiaries from what was reflected in the financial
          statements or projections previously furnished to the Lenders.

               (i)  Minimum   EBITDA.   The  Lenders  shall  be  satisfied  that

          that is satisfactory to the Lenders.

               (j) Solvency.  The Lenders  shall have received a certificate  of
          Newco  satisfactory in form and substance to the Lenders,  executed by

               (m) Opinions,  Representations and Warranties.  The Lenders shall
          be entitled to rely on all  representations,  warranties  and opinions
          given in connection with the Merger  Agreement and shall have received
          representations,   warranties  and  legal  opinions  covering  matters
          customary for high yield financings of the type contemplated.

               (n) Take-Out Banks. You shall have engaged one or more investment
          banks  satisfactory to the Lenders (the "Take-Out  Banks") to publicly
          offer or privately  place the Debt  Securities,  the proceeds of which
          will be used either,  in lieu of the Bridge  Loan,  to fund the Merger
          or, if the Bridge Loan is  outstanding,  to prepay in whole or in part
          the Bridge  Loan.  You and Newco shall have  prepared  (and shall have
          obtained the agreement of XYZ and ABC to assist in the preparation of)
          an offering memorandum relating to the issuance of the Debt Securities
          (which offering  memorandum shall contain  audited,  unaudited and pro
          forma financial  statements meeting the requirements of Regulation S-X
          under the Securities  Act of 1933, as amended,  of ABC for the periods
          required  of a  registrant  on Form  S-1) at  least  30 days  prior to
          funding  and  the  Take-Out   Banks  shall  have  been   afforded  the
          opportunity  to market and shall have  marketed  such Debt  Securities
          pursuant to such offering memorandum for such a period as is customary
          to complete the sale of securities  such as the Debt  Securities.  You
          and Newco shall have used all reasonable  commercial efforts to assist
          (and shall have  obtained the  agreement of XYZ and ABC to assist) the
          Take-Out Banks in marketing the Debt  Securities,  including,  without
          limitation,  having prepared the offering memorandum relating thereto,
          having made senior management of XYZ and ABC and other representatives
          of the  Partnership,  XYZ and ABC  available  (at  mutually  agreeable
          times) to  participate  in meetings  with  prospective  investors  and
          having provided such  information and assistance as the Take-Out Banks
          shall have  reasonably  requested  during the course of such marketing
          process.

                  Section 4. Securities Demand. The Financing Documentation will
provide that upon request (a "Request") from the Take-Out Banks made at any time
after the Closing Date while any  portion  of the Bridge  Loan  is  outstanding,
the  Partnership, Newco, XYZ and ABC shall take all reasonable actions necessary
or desirable,  to the extent  within  their  power,  so that the  Take-Out Banks
can,  as soon as practicable  after  such  Request, publicly  offer or privately
place  Debt Securities (the "Initial Request Date"). The Financing Documentation
will also provide that upon notice by the Take-Out Banks (a "Take-Out Securities
Notice"), at any time and from time to time following the Initial  Request Date,
Newco, XYZ and ABC will issue and  sell  Debt  Securities  upon  such  terms and
conditions as specified in the Take-Out Securities  Notice;  provided,  however,
that for either a Request or a Take-Out  Securities  Notice  (i) fixed  interest
rates  shall be determined  by  the   Take-Out   Banks  in  light  of  the  then
prevailing  market conditions,  but in no event  shall  the   interest   rate on
the Debt Securities exceed 17.00% per annum;  (ii)  the  maturity  of  any  Debt
Securities  shall not be earlier than six months after  the  scheduled  maturity
of the Credit  Facilities (as in effect on the Closing  Date);  (iii)  the  Debt
Securities will contain such terms,  conditions  and covenants  as are customary
for  similar  high  yield financings and as are satisfactory in  all respects to
the Take-Out Banks,  Newco  and  ABC;  and  (iv)  all  other  arrangements  with
respect to the Debt  Securities shall be reasonably satisfactory in all respects
to the Take-Out Banks, Newco, XYZ and  ABC  in  light  of  the  then  prevailing
market  conditions. CIBC and CMB agree that if one of the  Take-Out  Banks  (the
"Electing Bank") provides notice to  the other  Take-Out  Bank  (the  "Receiving
Bank")  that it desires to deliver a Request and Take-Out  Securities Notice and
the Receiving Bank does not desire to do so, no  Request or Take-Out  Securities
Notice will be delivered for 30  days, at  which  time  the  Electing  Bank  may
require the  Receiving  Bank to join in the delivery of a  Request  and Take-Out
Securities  Notice.  The foregoing shall not limit the  ability of Newco, XYZ or
ABC to  refinance the Bridge Loan by other means.

                  In addition, the Partnership,  Newco, XYZ and ABC covenant and
agree  subsequent  to the funding  date of any portion of the Bridge Loan to use
reasonable  best  efforts to assist the  Take-Out  Banks in  marketing  the Debt
Securities  to  refinance  the  Bridge  Loan,  including,   without  limitation,
preparing an offering memorandum  relating thereto,  making senior management of
ABC and other  representatives  of the  Partnership,  XYZ and ABC  available (at
mutually agreeable times) to participate in meetings with prospective  investors
and  providing  such  information  and  assistance  as the Take-Out  Banks shall
reasonably request during the course of such marketing process.

                  Section  5.  Indemnification  and  Contribution.  You agree to
indemnify the Lenders and each of their  respective  affiliates  and each person
in  control  of the Lenders and eac h of  their  respective  affiliates and  the
respective  officers, directors,  employees, agents  and  representatives of the
Lenders and their respective  affiliates and control persons, as provided in the
Indemnity Letter  dated  the date  hereof (the "Indemnity Letter") and  attached
hereto.

                  Section  6.  Expenses. In addition to any  fees  that  may  be
payable  to  the  Lenders  hereunder  and  regardless  of  whether  any  of  the
transactions  contemplated  by  this letter  are  consummated,  if  this  letter
agreement is terminated, the Bridge Loan  is  made  available or  the  Financing
Documentation  is  executed and  delivered,  you  hereby agree to  reimburse the
Lenders for all reasonable fees and  disbursements of  legal  counsel, including
but  not  limited  to the  reasonable  fees  and disbursements  of Cahill Gordon
& Reindel, the Lenders' special counsel and consultants, and all of the Lenders'
travel and other reasonable out-of-pocket expenses incurred in  connection  with
the Transaction or otherwise arising out of the Lenders' commitment hereunder.

                  Section  7.  Termination. The Lenders' commitment hereunder to
provide the Bridge Loan shall  terminate,  unless  expressly agreed  to  by  the
Lenders  in  their  sole discretion  to  be  extended to  another  date,  on the
earlier of (A) February 24, 2000  if  no  portion  of  the  Bridge Loan has been
funded (other than as a  result of failure  of  the  Lenders  to  fulfill  their
obligations  hereunder),  and (B) the termination  of  the  Merger  Agreement in
accordance  with the terms  thereof.  No such  termination  of  such  commitment
shall affect your obligations under Sections 5 and 6 hereof or this  Section  7,
which shall survive any such termination.

                 Section   8.  Assignment;  Syndication.  This letter  shall not
be assignable by any party hereto without the prior written consent of the other
parties (other than, in the case of the Lenders, to an affiliate of such Lender,
it being understood that any such affiliate shall be subject to the restrictions
set forth in this Section  8);  provided,  however,  that the Lenders shall have
the right,  in a manner agreeable to one another, to syndicate  the Bridge  Loan
and  the  commitment  with  respect  thereto  among  banks  or  other  financial
institutions pursuant to the Financing  Documentation or otherwise and to  sell,
transfer or assign all or any portion  of,  or  interests  or participations in,
the  Bridge  Loan  and the commitment  with respect thereto and any notes issued
in connection therewith. The Partnership, Newco, XYZ and ABC agree, upon request
of the Lenders,  to use reasonable  best  efforts,  whether  prior  to or  after
the  funding  date of any Bridge  Loan,  to assist the  Lenders  in  syndicating
the  Bridge  Loan or the commitment with  respect  thereto,  including,  without
limitation,  in connection with (x) the preparation of  an  information  package
regarding  the  Transaction,  including  the  Information  and  the  Projections
described in  Section  1 hereof,  and (y) meetings and other communications with
prospective  Lenders,  including  making  senior  management  of  ABC  and other
representatives  of  the  Partnership,  XYZ  and  ABC  available  (at   mutually
agreeable times)  to  participate  in such meetings. The Lenders  agree  between
themselves  that  neither  the Lenders nor any  of their respective  direct  and
indirect  transferees  shall syndicate,  sell,  transfer, assign, participate or
otherwise  reduce  or  transfer  their  risk (including by way of derivatives or
otherwise)(each, a "Disposition") for 180 days following the date of this letter

                                181-270                             100 bp

                                 91-180                         101.0%

Mandatory Prepayment
 and  Change  in  Control: Net proceeds (except for proceeds from the  financing
                           used  to consummate the Acquisition) of sales of debt
                           securities or equity securities, in a public offering
                           or private  placement by the  Borrower or  any of its
                           subsidiaries, shall, to the extent permitted, be used
                           to prepay the Bridge  Loan plus  accrued interest and
                           any other  amount  payable  thereunder  to  the  full
                           extent of the net  proceeds so received to the extent

                           principal amount plus accrued  interest and otherwise
                           in a  manner  reasonably  acceptable  to the  Lenders
                           and the Borrower.

 ment or Syndication:      The Lenders may participate out or sell or assign, or
                           syndicate to other lenders, the Bridge Loan, in whole

                           applicable securities laws and the  agreement between
                           themselves.

                           terms  to  the  Bridge  Loan,  and  other  terms  and
                           conditions  customary  for high yield debt securities
                           issued  for cash  in the then  prevailing  market and
                           acceptable to the Lenders and the Borrower and  shall
                           in  addition  provide customary registration  rights,
                           including, without limitation, a  registered exchange

                           affirmative and  negative  covenants (with  customary
                           carve-outs and exceptions), including, without  limi-

Acquisition,  L.P. The parties hereto agree that the section entitled "Mandatory
Prepayment and Change in Control" in Exhibit A to the Commitment Letter shall be
amended to read as follows:

         Net proceeds (except for proceeds from the financing used to consummate
         the Acquisition) of sales of debt securities or equity securities, in a
         public  offering or private  placement by the Borrower,  shall,  to the
         extent  permitted,  be used to prepay  the  Bridge  loan  plus  accrued
         interest and any other amount payable  thereunder to the full extent of
         the net  proceeds so received to the extent such net  proceeds  are not
         used to retire senior bank debt.  The Borrower will be required to make
         an offer to purchase all notes  outstanding  under the Bridge Loan,  to
         the extent permitted by the Senior Credit  Facilities,  as the case may
         be, upon the  occurrence of a Change of Control (to be defined) at 101%
         of  principal  amount plus accrued  interest and  otherwise in a manner
         reasonably acceptable to the Lenders and the Borrower.

duly executed and delivered by their proper and duly  authorized  officers as of

              Re: Texas-New Mexico Power Company Acquisition Financing


Ladies and Gentlemen:

                  We  understand  that CIBC World  Markets  Corp.  ("CIBC")  and
certain other investors (the "Equity  Investors")  through SW Acquisition,  L.P.
(the "Partnership") has formed an acquisition  subsidiary,  ST Acquisition Corp.
("Newco"),  which  intends to enter into a  transaction  pursuant to which Newco
will merge (the "Merger") with and into TNP Enterprises, Inc. ("XYZ"), a holding
company that owns Texas-New Mexico Power Company ("ABC"). In connection with the
Merger,  the  former  shareholders  of  XYZ  will  become  entitled  to  receive
approximately  $590.0  million (or $44.00 per share,  net to the seller) in cash
and the  Partnership  will  become the owner of all the  issued and  outstanding
capital stock of XYZ. We further  understand that the funding  requirements  for
the Merger  (including  related fees and expenses) will be approximately  $640.0
million and such amount,  together with ongoing working  capital needs,  will be
provided  solely  from (i) a senior  secured  term  loan  and  revolving  credit
facility  of  Newco  (the  "Credit   Facilities")   of  up  to  $165.0   million
(approximately  $25.0  million  of the  revolving  credit  portion of the Credit
Facilities to be drawn on the closing date of the Merger (the "Closing  Date")),
(ii) a backstop  facility of ABC with aggregate  availability  of $428.0 million
(the  "Backstop  Facility"),  (iii) not less than a $100.0 million common equity
investment by the Equity  Investors in the Partnership and the investment by the
Partnership in Newco of a portion of such amount which,  together with the other
financing, is sufficient to consummate the Merger (the "Equity Financing"), (iv)
the  issuance  and sale of  Preferred  Shares  (as  defined  below)  and (v) the
issuance and sale of up to $275.0  million  aggregate  principal  amount of debt
securities  pursuant to an  engagement  letter of even date  herewith  among the
parties  hereto ("Debt  Securities").  The Merger,  the Credit  Facilities,  the
Backstop  Facility,  the Equity  Financing,  the bridge loan contemplated by the
commitment letter among CIBC, The Chase Manhattan Bank ("CMB"),  the Partnership
and Newco of even date  herewith (the "Bridge  Loan"),  the issuance and sale of
the bridge preferred stock contemplated by this letter and the issuance and sale
of the Preferred Shares and the Debt Securities are herein collectively referred
to as the "Transaction."

         In  connection  with  the  Transaction,  you have  engaged  one or more
investment banks reasonably satisfactory to the Purchasers (as defined below) to
sell or place preferred equity securities of Newco (the "Preferred Shares").

         You  have  requested  that  CIBC,  CMB,  Continental  Casualty  Company
("Continental")   and  Laurel  Hill  Capital   Partners   LLC  ("Laurel   Hill")
(collectively,  the "Purchasers") commit to purchase from Newco senior preferred
stock of Newco (the "Bridge Preferred  Stock") with a liquidation  preference of
up to $32.5 million, $32.5 million, $32.5 million and $2.5 million, respectively
($100.0 million in the aggregate), as described in Section 1 hereof.

         Accordingly,   subject  to  the  terms  and  conditions  set  forth  or
incorporated in this letter, the Purchasers agree with you as follows:

         Section 1. Purchase of Bridge Preferred  Stock.  The Purchasers  hereby
commit,  on an equal, but not joint and several,  basis subject to the terms and
conditions  hereof and in the Summary  Term Sheet  attached  hereto as Exhibit A
(collectively,  the "Term Sheet"), to purchase from Newco senior preferred stock
of Newco on the Closing Date with an aggregate  liquidation  preference of up to
$100.0 million. The proceeds of the sale of Bridge Preferred Stock shall be used
solely to finance the Merger and to pay fees and expenses incurred in connection
therewith.  The principal terms of the Bridge  Preferred Stock are summarized in
the Term Sheet.

         Unless the Purchasers'  commitment hereunder shall have been terminated
pursuant to Section 7, the Purchasers shall have the exclusive right to purchase
the Bridge  Preferred Stock and CIBC and CMB or their  Affiliates shall have the
exclusive  right to purchase any other bridge or interim  financing  required in
connection with the Transaction.

         You  hereby  represent  and  covenant  that  based on your  review  and
analysis,  (a) all information  other than  Projections (as defined below) which
has  been  or is  hereafter  made  available  to the  Purchasers  by you or your
representatives,  advisors or  affiliates in  connection  with the  transactions
contemplated hereby (the "Information") has been reviewed and analyzed by you in
connection  with the  performance  of your own due diligence and, to the best of
your knowledge,  is, or in the case of Information made available after the date
hereof  will be,  correct  in all  material  respects  and does not and will not
contain any untrue statement of a material fact or omit to state a material fact
known to you and  necessary to make the  statements  contained  therein,  in the
light of the  circumstances  under which such  statements  were or are made, not
misleading,  (b) to the best of your knowledge,  the consolidated EBITDA of XYZ,
ABC and their consolidated subsidiaries for the year ended December 31, 1998 was
at least $135.0 million and (c) all financial  projections  concerning  ABC, XYZ
and Newco that have been or are hereafter  made  available to the  Purchasers by
you or your  representatives,  advisors or  affiliates  in  connection  with the
transactions  contemplated  hereby (the "Projections") have been or, in the case
of Projections  made available  after the date hereof,  will be prepared in good
faith  based  upon  reasonable   assumptions  (it  being   understood  that  the
Projections are subject to significant uncertainties and contingencies,  many of
which are  beyond  your  control  and that no  assurance  can be given that such
Projections  will be realized).  You agree to supplement the Information and the
Projections  from  time  to  time  until  the  termination  of  the  Purchasers'
commitment  hereunder  so  that  the  representation  and  warranty  made in the
preceding  sentence is correct as of such date. In selling any Bridge  Preferred
Stock,  the  Purchasers  will be using and  relying on the  Information  and the
Projections. The representations and covenants contained in this paragraph shall
remain  effective  until  definitive   financing  agreements  are  executed  and
thereafter the disclosure  representations  contained herein shall be terminated
and of no further  force and effect.  For purposes of this  Agreement,  "EBITDA"
means,  for any period,  the  aggregate  amount of  Consolidated  Net Income (as
defined), after adding thereto interest charges,  interest income, income taxes,
depreciation and amortization,  amortization of regulatory assets,  amortization
or  intangibles,   non-cash  regulatory   deferrals  and  other   amortizations,
extraordinary items, and any other non-cash non-recurring items.

         The Purchasers shall be entitled to change the terms,  structure and/or
pricing of the Bridge  Preferred  Stock if they  determine that such changes are
advisable in order to ensure a successful syndication;  provided,  however, that
in no event shall the aggregate  liquidation  preference of the Bridge Preferred
Stock be lowered.

         Section  2.  Financing  Documentation.   The  purchase  of  the  Bridge
Preferred Stock will be governed by definitive  purchase and related  agreements
and  documentation  (collectively,  the "Financing  Documentation")  in form and
substance  reasonably  satisfactory  to the Purchasers and to you. The Financing
Documentation  shall be prepared by Cahill Gordon & Reindel,  special counsel to
the Purchasers.  The Financing Documentation shall contain such covenants, terms
and  conditions as are  consistent  with this letter and the Term Sheet and such
other covenants,  terms, conditions,  representations,  warranties, and remedies
provisions as shall be satisfactory to the Purchasers and you.

         Section 3. Conditions. The obligation of the Purchasers under Section 1
of this letter to purchase the Bridge  Preferred Stock is subject to fulfillment
of the following conditions:

                  (a) Merger  Agreement.  The  Partnership  and Newco shall have
         entered  into  an  agreement   relating  to  the  Merger  (the  "Merger
         Agreement") on terms and in form and substance substantially consistent
         with the terms of the Merger Agreement reviewed by the Purchasers prior
         to the execution by the Partnership of this letter  including,  without
         limitation,  the payment to the former  shareholders of XYZ of not more
         than $44.00 per share,  net to the seller in cash. The Merger Agreement
         shall  not have  been  amended  in any  material  respect  without  the
         Purchasers'  written  consent,  which consent shall not be unreasonably
         withheld.  All  conditions  precedent  to the Merger  contained  in the
         Merger   Agreement   shall  have  been   performed  or  complied   with
         substantially on the terms set forth therein and not waived without the
         Purchasers'  written  consent,  which consent shall not be unreasonably
         withheld  and   simultaneously   with  any  drawing  under  the  Credit
         Facilities,  the making of the Bridge  Loan or the  purchase  of Bridge
         Preferred Stock, the Merger shall have been consummated.

                  (b) Financing  Documentation.  Newco,  ABC and the  Purchasers
         shall have entered  into the  Financing  Documentation  relating to the
         Bridge  Preferred Stock and the  transactions  contemplated  thereby on
         terms  and  in  form  and  substance  reasonably  satisfactory  to  the
         Purchasers and Newco.

                  (c) The  Credit  Facilities,  the  Backstop  Facility  and the
         Bridge Loan. Newco, ABC and the lenders  applicable  thereto shall have
         entered into  documentation  with respect to the Credit  Facilities and
         the Backstop Facility (the "Senior  Documentation") and the Bridge Loan
         (the "Bridge Loan  Documentation")  on terms and conditions  (including
         with  respect  to  funding)  and  in  form  and  substance   reasonably
         satisfactory  to the Purchasers.  All conditions to funding  thereunder
         shall  have been  satisfied  or waived  only  with the  consent  of the
         Purchasers,  not  to  be  unreasonably  withheld.  Neither  the  Senior
         Documentation  nor  the  Bridge  Loan  Documentation  shall  have  been
         amended,  without the Purchasers'  consent,  which consent shall not be
         unreasonably withheld.

                  (d) Equity  Financing.  On or prior to the Closing Date, Newco
         shall have received a common equity  investment of not less than $100.0
         million,  which shall be provided by the Equity  Investors  through the
         Partnership.  The terms and conditions of the Equity  Financing and any
         tax sharing arrangement shall be satisfactory to the Purchasers.

                  (e) No Adverse Change or Development, Etc. (i) There shall not
         have occurred since the date of the most recent financial statements of
         XYZ a  material  adverse  effect  on  the  rights  or  remedies  of the
         Purchasers,  or on the ability of Newco to perform its  obligations  to
         the Purchasers or on the business,  property, assets, nature of assets,
         liabilities,  condition (financial or otherwise), results of operations
         or prospects of ABC;  (ii) trading in  securities  generally on the New
         York or American Stock Exchange shall not have been suspended;  minimum
         or maximum prices shall not have been established on any such exchange;
         (iii) a banking  moratorium shall not have been declared by New York or
         United  States  authorities;  and (iv) there shall not have been (A) an
         outbreak  or  escalation  of  material  hostilities  between the United
         States and any foreign  power,  or (B) an outbreak or escalation of any
         other  material  insurrection  or armed  conflict  involving the United
         States or any other national or international calamity or emergency, or
         (C) any material change or disruption in the general  financial banking
         or capital  markets of the United  States  which,  in each case, in the
         reasonable  judgment of the Purchasers  would  materially and adversely
         affect or impair the ability to sell or place the Preference  Shares or
         the Bridge Preferred Stock.

                  (f)  Capital  Structure.  The pro forma  consolidated  capital
         structure of Newco, ABC and XYZ, after giving effect to the Transaction
         (including  all  adjustments  permitted  by  Regulation  S-X  under the
         Securities Act of 1933),  shall be consistent in all material  respects
         with the Projections and capital structure contemplated herein.

                  (g) Governmental  and Third Party Approvals.  All governmental
         and third  party  approvals  required by the Merger  Agreement  and any
         other  material  governmental  and third  party  approvals  required in
         connection  with the  financing  contemplated  hereby  shall  have been
         obtained on  reasonably  satisfactory  terms and shall be in full force
         and effect,  and all  applicable  waiting  periods  shall have  expired
         without any action being taken or threatened by any competent authority
         that would  materially  restrain,  prevent or otherwise impose material
         adverse conditions on the financing thereof.

                  (h) Financial  Statements.  The Purchasers shall have received
         (i)satisfactory  audited  financial  statements  of XYZ and ABC for the
         three most recent fiscal years for which such financial  statements are
         available and (ii)satisfactory unaudited interim consolidated financial
         statements  of XYZ and ABC for each fiscal month and  quarterly  period
         ended after the latest fiscal year referred to in clause(i) above as to
         which  such  financial  statements  are  available  and such  financial
         statements  shall  not  reflect  any  material  adverse  change  in the
         consolidated  financial  conditions of XYZ and ABC and their respective
         subsidiaries  from what was  reflected in the  financial  statements or
         projections previously furnished to the Purchasers.

                  (i) Minimum  EBITDA.  The  Purchasers  shall be satisfied that
         Consolidated EBITDA of XYZ, ABC and their consolidated subsidiaries for
         the  latest  twelve  month  period  for  which the  relevant  financial
         information  is available  shall equal at least $135.0  million and the
         Partnership shall provide support for such calculation of a nature that
         is satisfactory to the Purchasers.

                  (j) Solvency. The Purchasers shall have received a certificate
         of Newco satisfactory in form and substance to the purchasers, executed
         by the Chief  Executive  Officer or Chief  Financial  Officer of Newco,
         that shall  certify the  solvency of Newco and its  subsidiaries  after
         giving  effect to the  Merger and the other  transactions  contemplated
         hereby.

                  (k) Power Market  Study.  The  Purchasers  shall have received
         within  120  days  of the  date  thereof  a  power  market  study  by a
         satisfactory  independent  power  marketing  consultant,  in  form  and
         substance satisfactory to the Purchasers.

                  (l)  Environmental  Audit.  The  Lenders  shall have  received
         within 120 days of the date of the Commitment Letter to which this term
         sheet is attached an  environmental  audit with respect to certain real
         property owned or leased by XYZ, ABC and their subsidiaries from a firm
         acceptable  to the  Lenders,  which audit shall not reveal any material
         adverse change in XYZ, ABC and their subsidiaries.

                  (m) Opinions,  Representations and Warranties.  The Purchasers
         shall  be  entitled  to rely  on all  representations,  warranties  and
         opinions given in connection  with the Merger  Agreement and shall have
         received  representations,   warranties  and  legal  opinions  covering
         matters   customary  for  preferred  equity   financings  of  the  type
         contemplated.

                  (n)  Take-Out  Banks.  You  shall  have  engaged  one or  more
         investment banks  satisfactory to the Purchasers (the "Take-Out Banks")
         to publicly offer or privately place the Preferred Shares, the proceeds
         of which will be used either, in lieu of the Bridge Preferred Stock, to
         fund the Merger or, if the Bridge  Preferred Stock is  outstanding,  to
         redeem in whole or in part the Bridge  Preferred  Stock.  You and Newco
         shall have  prepared  (and shall have obtained the agreement of XYZ and
         ABC to assist in the preparation of) an offering memorandum relating to
         the issuance of the Preferred  Shares (which offering  memorandum shall
         contain audited,  unaudited and pro forma financial  statements meeting
         the requirements of Regulation S-X under the Securities Act of 1933, as
         amended,  of ABC for the periods  required of a registrant on Form S-1)
         at least30 days prior to funding and the Take-Out Banks shall have been
         afforded  the  opportunity  to market  and  shall  have  marketed  such
         Preferred Shares pursuant to such offering memorandum for such a period
         as is  customary  to  complete  the  sale  of  securities  such  as the
         Preferred  Shares.  You  and  Newco  shall  have  used  all  reasonable
         commercial  efforts to assist (and shall have obtained the agreement of
         XYZ and ABC to assist) the Take-Out  Banks in marketing  the  Preferred
         Shares,  including,  without  limitation,  having prepared the offering
         memorandum  relating thereto,  having made senior management of XYZ and
         ABC and other representatives of the Partnership, XYZ and ABC available
         (at  mutually   agreeable   times)  to  participate  in  meetings  with
         prospective   investors  and  having  provided  such   information  and
         assistance as the Take-Out Banks shall have reasonably requested during
         the course of such marketing process.

         Section 4. Securities Demand. The Financing  Documentation will provide
that upon request (a "Request")  from the Take-Out  Banks made at any time after
the Closing Date while any amount of the Bridge  Preferred Stock is outstanding,
the Partnership,  Newco, XYZ and ABC shall take all reasonable actions necessary
or desirable,  to the extent within their power, so that the Take-Out Banks can,
as soon as practicable  after such Request,  publicly  offer or privately  place
Preferred Shares (the "Initial Request Date"). The Financing  Documentation will
also  provide that upon notice by the  Take-Out  Banks (a  "Take-Out  Securities
Notice"),  at any time and from time to time following the Initial Request Date,
Newco,  XYZ and ABC will  issue and sell  Preferred  Shares  upon such terms and
conditions as specified in the Take-Out  Securities Notice;  provided,  however,
that for either a Request or a Take-Out  Securities  Notice (i)  dividend  rates
shall be determined by the Take-Out Banks in light of the then prevailing market
conditions,  but in no event shall the  dividend  rate on the  Preferred  Shares
exceed  18.00% per annum;  (ii) the  Preferred  Shares will  contain such terms,
conditions  and  covenants as are customary  for similar  financings  and as are
satisfactory  in all  respects to the Take-Out  Bank,  after  consultation  with
Newco,  XYZ and ABC;  and (iii)  all  other  arrangements  with  respect  to the
Preferred  Shares  shall  be  reasonably  satisfactory  in all  respects  to the
Take-Out Bank, after  consultation with Newco, XYZ and ABC, in light of the then
prevailing  market  conditions.  CIBC and CMB agree that if one of the  Take-Out

         Section 6. Expenses. In addition to any fees that may be payable to the
Purchasers   hereunder  and  regardless  of  whether  any  of  the  transactions

purchase the Bridge Preferred Stock shall terminate,  unless expressly agreed to
by the  Purchasers  in their sole  discretion to be extended to another date, on

has been  purchased  (other  than as a result of  failure of the  Purchasers  to
fulfill their  obligations  hereunder),  and (B) the  termination  of the Merger
Agreement in accordance  with the terms  thereof.  No such  termination  of such
commitment shall affect your  obligations  under Sections 5 and 6 hereof or this
Section 7, which shall survive any such termination.

         Section 8. Assignment. This letter shall not be assignable by any party
hereto  without the prior written  consent of the other parties  (other than, in
the  case of the  Purchasers,  to an  affiliate  of  such  Purchaser,  it  being
understood  that any such  affiliate  shall be subject to the  restrictions  set
forth in this Section 8); provided,  however, that the Purchasers shall have the
right, in a manner agreeable to one another,  to sell, transfer or assign all or
any portion of, or interests in, the Bridge  Preferred  Stock and the commitment
with respect thereto. The Partnership, Newco, XYZ and ABC agree, upon request of
the Purchasers,  to use reasonable  best efforts,  whether prior to or after the

the Bridge  Preferred Stock or the commitment with respect  thereto,  including,
without  limitation,  in connection  with (x) the  preparation of an information

affiliates or a Disposition  thereof by CIBC World Markets Corp., with an option
to CMB, Continental and Laurel Hill to participate pro rata in such Disposition.

six-month  anniversary of the Closing Date,  such party shall provide each other
Purchaser at such time the option to participate  pro rata in such  Disposition.
To the extent that any  Purchasers  sell  limited  partnership  interests of the
Partnership with their Bridge Preferred Stock prior to the six-month anniversary
of the Closing Date,  such Purchasers  will make available  limited  partnership
interests of the Partnership to any Purchaser  participating  in the Disposition
that does not own any such limited partnership interests on terms to be mutually
satisfactory to permit such Purchaser to participate in the Disposition on a pro
rata basis.

                        SENIOR SECURED CREDIT FACILITIES
                  Statement of Indicative Terms and Conditions

                  SW Acquisition, L.P. (the "Partnership"), a partnership formed
by CIBC World Markets Corp. and certain other investors (the  "Sponsors"),  have
formed an acquisition  subsidiary,  ST Acquisition Corp., which intends to enter
into a transaction  pursuant to which it will merge (the "Merger") with and into
TNP  Enterprises,  Inc.  ("TNP"),  a holding  company that owns Texas New Mexico
Power  Company,   ("TNMPCo").   In  connection  with  the  Merger,   the  former
shareholders of TNP will become entitled to receive  approximately  $590,000,000
in cash ($44 per share net to each  shareholder),  and the Sponsors  will become
the owners of all the issued and  outstanding  capital stock of TNP. The sources
and uses of funds  needed to effect the Merger and to pay the fees and  expenses
in  connection  therewith  are set forth on  Annex II  hereto (the "Table"). Set
forth below is a statement of indicative terms and conditions for senior secured
credit  facilities  to be used to  finance a portion of the  consideration  with
respect to the Merger.

                    shall be merged with TNP, and the surviving  corporation  of

                    entities,  including  CIBC  and  The  Chase  Manhattan  Bank
                    ("Chase"),  arranged by the Co-Arrangers (collectively,  the
                    "Lenders").

II.  Types and Amounts of Facilities

     A.  Term Facility

Type and Amount     A  six-year  term   loan  facility  (the "Term Facility") in
of the Facility:    an   aggregate  principal  amount   equal  to   $140,000,000
                    (the loans thereunder, the  "Term Loans").  The  Term  Loans
                    shall be due and  payable on  the sixth  anniversary  of the
                    Closing Date (as defined below).

                    Closing Date.

                    portion of the Merger and to pay related fees and expenses.

     B.  Revolving Facility

Type and Amount     A  three-year  revolving  credit facility  (the of facility:
                    "Revolving  Facility" and, together with the Term  Facility,
                    the  "Credit  Facilities";  the commitments  thereunder, the
                    "Revolving Commitments") in the amount  of $25,000,000  (the
                    loans  thereunder,  together with (unless the context other-
                    wise requires), the  Swingline Loans referred to  below, the
                    "Revolving Loans").

Availability:       The  Revolving  Facility  shall be  available on a revolving
                    basis during the period  commencing  on the Closing Date and
                    ending on the third  anniversary  of the  Closing  Date (the
                    "Revolving Termination Date").

Swingline Loans:    A  portion of  the  Revolving  Facility  not in excess of an

                    availability  under  the  Revolving  Facility  on  a dollar-
                    for-dollar  basis. Each Lender under the  Revolving Facility
                    shall  acquire, under certain  circumstances, an irrevocable
                    and unconditional  pro rata participation in each  Swingline
                    Loan.

Maturity:           The Revolving Termination Date.

Purpose:            The proceeds of the Revolving Loans shall be used to finance
                    the working capital needs and general corporate  purposes of
                    the Borrower and its  subsidiaries in the ordinary course of

                    Closing"  set forth  below)  after the  Closing  Date by the

                    worn-out  property in the ordinary  course of  business  and
                    subject  to  certain  other customary  exceptions (including
                    capacity for reinvestment) to be agreed upon.

                    The amounts  described  above shall be  applied,  first,  to
                    prepay the Term Loans and, second, to permanently reduce the
                    Revolving  Commitments (with extensions of credit thereunder
                    being  prepaid to the extent the  aggregate  amount  thereof
                    exceeds the Revolving Commitments as so reduced).

                    Facilities  and any interest rate  protection  agreements in
                    respect thereof  provided by any Lender (or any affiliate of
                    a Lender)  shall be secured by a  perfected  first  priority
                    security interest in all of the capital stock of TNMPCo.

                    significantly   less  favorable  to  the  Borrower  and  its
                    subsidiaries  than the Texas  Transition to Competition Plan
                    and  the  rate  plans  applicable  to the  Borrower  and its
                    subsidiaries in the state of New Mexico on the date hereof.

                    (h) The Lenders shall have received reasonably  satisfactory
                    unaudited interim  consolidated  financial statements of TNP
                    for each  fiscal  month and  quarterly  period  ended  after
                    December 31, 1998 as to which such financial  statements are
                    available and such  financial  statements  shall not reflect
                    any material  adverse change in the  consolidated  financial
                    condition  of  TNP  and  its  subsidiaries   from  what  was
                    reflected  in  the  financial   statements  or   projections
                    previously furnished to the Lenders.

                    (i)  The   Lenders   shall  have   received   a   reasonably
                    satisfactory  pro forma  consolidated  balance  sheet of the

                    recent  quarterly   consolidated   balance  sheet  delivered
                    pursuant  to  the  preceding  paragraph  consistent  in  all
                    material  respects with the pro forma  consolidated  balance
                    sheet attached  hereto as Annex III (except to the extent of
                    differences  that reflect normal  operations of the Borrower
                    during the period between  December 31, 1998 and the date as
                    of which such pro forma balance sheet shall be prepared).

                    of TNP and  its  subsidiaries  (to be  defined  in a  manner

                    attached  hereto  as Annex IV) for the  latest  twelve-month
                    period  for  which the  relevant  financial  information  is
                    available shall equal at least $135,000,000 and the Borrower
                    shall provide support for such  calculation of a nature that
                    is  satisfactory  to the Lenders for  inclusion in marketing
                    materials for the Credit Facilities.

                    (k) All  actions  required  to  perfect  the  Administrative

                    and that insurance is maintained on all property in at least
                    such amounts and against at least such risks (but  including
                    in  any  event  public  liability,   product  liability  and
                    business interruption) as are usually insured against in the
                    same  general  area by  companies  engaged  in the same or a
                    similar business.

                    (m) The Lenders  shall have  received a  certificate  of the
                    Borrower,  reasonably  satisfactory in form and substance to
                    the  Lenders,  executed  by the Chief  Executive  Officer or
                    Chief Financial Officer of the Borrower,  that shall certify
                    the  solvency of the  Borrower  and its  subsidiaries  after
                    giving  effect  to the  Merger  and the  other  transactions
                    contemplated hereby.

                    Co-Arrangers,  which  audit  shall not reveal any  condition
                    which  reasonably  could be expected to result in a material
                    adverse  change  in  the  business,  operations,   property,
                    conditions  (financial  or  otherwise)  or  prospects of the

                    TNP pursuant to the Merger,  accompanied by reliance letters

                    satisfactory  evidence  that,  after  giving  effect  to the
                    Merger,  TNMPCo's  senior  unsecured  long  term  debt  will
                    continue to be rated as investment grade.

                    provisions  (a)  protecting  the Lenders  against  increased

                    tax, capital adequacy and other requirements of law and from
                    the  imposition of or changes in  withholding or other taxes

                    incurred  in  connection  with,  among  other  things,   any
                    prepayment of a Eurodollar Loan (as defined in Annex I) on a
                    day  other  than  the last day of an  interest  period  with
                    respect thereto.

     Expenses and
     Indemnifi-
     cation:        The  Borrower  shall  pay (a) all  reasonable  out-of-pocket
                    expenses of the  Administrative  Agent and the  Co-Arrangers
                    associated with the syndication of the Credit Facilities and
                    the preparation,  execution,  delivery and administration of
                    the Senior Credit  Documentation and any amendment or waiver
                    with  respect  thereto   (including  the  reasonable   fees,
                    disbursements  and other  charges  of  counsel)  and (b) all
                    out-of-pocket  expenses of the Administrative  Agent and the
                    Lenders (including the fees, disbursements and other charges
                    of counsel) in connection with the enforcement of the Senior
                    Credit Documentation.

                    The  Administrative  Agent, the Co-Arrangers and the Lenders
                    (and  their  affiliates  and  their   respective   officers,
                    directors,  employees,  advisors  and  agents)  will have no
                    liability  for, and will be  indemnified  and held  harmless
                    against,  any  losses,  claims,   damages,   liabilities  or
                    expenses  incurred in respect of the financing  contemplated
                    hereby or the use or the proposed  use of proceeds  thereof,
                    except   to  the   extent   they  are   found  by  a  final,
                    non-appealable judgment of a court to arise from the willful
                    misconduct or gross  negligence of the relevant  indemnified
                    person.

                                                                    to Exhibit A

                    Interest and Certain Fees
     Interest
     Rate
     Options:       The  Borrower  may  elect  that  the  Loans  comprising each
                    borrowing bear interest at a rate per annum equal to:

                      The ABR plus the Applicable Margin; or

                      The Eurodollar Rate plus the Applicable Margin.

                    Provided, that all Swingline Loans shall bear interest based
                    upon the ABR.

                    As used herein:

                    "ABR" means the higher of (i) the rate of interest  publicly
                    announced  by  CIBC  as its  prime  rate  in  effect  at its
                    principal  office in New York City (the  "Prime  Rate")  and
                    (ii) the federal funds effective rate from time to time plus
                    0.5%.

                    "Applicable Margin" means:

                    (a) with respect to the Revolving Loans  and the Term  Loan,
                    (i) 2.00%, in the case of ABR Loans (as  defined  below) and
                    (ii) 3.00 %, in the case of Eurodollar  Loans  (as  defined
                    below);

                    "Eurodollar  Rate" means the rate  (adjusted  for  statutory
                    reserve  requirements  for  eurocurrency   liabilities)  for
                    eurodollar deposits for a period equal to one, two, three or
                    six months (as selected by the  Borrower)  appearing on Page
                    3750 of the Dow Jones Markets screen.

     Interest
     Payment
     Dates:         In the case of Loans  bearing  interest  based  upon the ABR
                    ("ABR Loans"), quarterly in arrears.

                    In the  case  of  Loans  bearing  interest  based  upon  the
                    Eurodollar  Rate  ("Eurodollar  Loans"),  on the last day of
                    each  relevant  interest  period  and,  in the  case  of any
                    interest period longer than three months, on each successive
                    date  three  months  after the  first  day of such  interest
                    period.

     Commitment
     Fees:          The Borrower  shall pay a commitment  fee  calculated at the
                    rate of .50% per annum on the average  daily unused  portion
                    of the  Revolving  Facility,  payable  quarterly in arrears.
                    Swingline  Loans shall,  for purposes of the  commitment fee
                    calculations  only, not be deemed to be a utilization of the
                    Revolving Facility.

     Default
     Rate:          At any time when the  Borrower  is in default in the payment
                    of any amount of principal due under the Credit  Facilities,
                    such  amount  shall bear  interest  at 2.00%  above the rate
                    otherwise  applicable  thereto.  Overdue interest,  fees and
                    other  amounts  shall bear  interest at 2.00% above the rate
                    applicable to ABR Loans.

     Rate and
     Fee Basis:     All per annum  rates shall be  calculated  on the basis of a
                    year of 360 days (or 365/366  days, in the case of ABR Loans
                    the  interest  rate  payable  on which is then  based on the
                    Prime Rate) for actual days elapsed.

Attention:

Ladies and Gentlemen:

                  Reference is made to the Commitment  Letter dated May 22, 1999
among CIBC World Markets Corp.,  Canadian  Imperial Bank of Commerce,  The Chase
Manhattan  Bank,  Chase  Securities  Inc. and ST  Acquisition  Corp. The parties
hereto  agree that the section  titled  "Mandatory  Prepayments  and  Commitment
Reductions"  in Exhibit A to the  Commitment  Letter shall be amended to read as
follows:

         "The  following  amounts  shall be applied to prepay the Term Loans and
         reduce the Revolving Commitments:

                           (a) 100% of the net  proceeds of any sale or issuance
                           of  equity  and  100%  of  the  net  proceeds  of any
                           incurrence of indebtedness (other than the financings
                           referred to in paragraphs (b) and (c) of the "Initial
                           Conditions  to Closing"  set forth  below)  after the
                           Closing Date by the Borrower; and

                           (b)  100% of the net  proceeds  of any  sale or other
                           disposition  (including  as a result of  casualty  or
                           condemnation)   by  the   Borrower   or  any  of  its
                           subsidiaries  of any  assets,  except for the sale of
                           inventory,   receivables   or  obsolete  or  worn-out
                           property  in the  ordinary  course  of  business  and
                           subject  to  certain   other   customary   exceptions
                           (including  capacity for  reinvestment)  to be agreed
                           upon,  provided  that the amount of such net proceeds
                           from the sale or other  disposition  of assets by any
                           of the  Borrower's  subsidiaries  shall be limited to
                           the portion  thereof that shall remain after such net
                           proceeds are first applied to prepay any indebtedness
                           of such  subsidiary in accordance  with any mandatory
                           prepayment or redemption  provisions thereof and that
                           shall  be able  (after  receipt  of any  governmental
                           approvals now or hereafter  required) to be paid as a
                           dividend  by such  subsidiary  to the  Borrower  (the
                           Borrower  agreeing  to use its best  efforts to cause
                           such dividend to be so paid).

                           The amounts described above shall be applied,  first,
                           to prepay the Term Loans and, second,  to permanently
                           reduce the Revolving  Commitments (with extensions of
                           credit  thereunder  being  prepaid  to the extent the
                           aggregate   amount  thereof   exceeds  the  Revolving
                           Commitments as so reduced).

Attention:

Ladies and Gentlemen:

                  You have advised Canadian Imperial Bank of Commerce  ("CIBC"),
CIBC World  Markets  Corp.  ("CIBC World  Markets"),  The Chase  Manhattan  Bank
("Chase")  and Chase  Securities  Inc.  ("CSI") that SW  Acquisition,  L.P. (the
"Partnership"),  a  partnership  formed by CIBC World  Markets and certain other
investors (the "Sponsers"), has formed an acquisition subsidiary, ST Acquisition
Corp. which intends to enter into a transaction pursuant to which ST Acquisition
Corp. will merge (the "Merger") with and into TNP Enterprises,  Inc. ("TNP"),  a
holding  company that owns Texas New Mexico Power Company (the  "Borrower").  In
connection with the Merger, the former  shareholders of TNP will become entitled
to  receive  approximately  $590,000,000  in cash  ($44  per  share  net to each
shareholder),  and the  Sponsers  will  become  the owners of all the issued and
outstanding  capital stock of TNP. As a result of the Merger outstanding debt of
the Borrower in an aggregate  amount of up to $428,000,000  could become due and
payable. In such connection,  you have requested that (i) CIBC World Markets and
CSI agree to structure,  arrange and syndicate a senior backstop credit facility
in the aggregate amount of $428,000,000 the proceeds of which shall be available
to refinance such debt (the  "Facility"),  (ii) CIBC and Chase commit to provide
the  entire   principal   amount  of  the  Facility  and  (iii)  CIBC  serve  as
administrative agent for the Facility.

                  Each of  CIBC  and  Chase  is  pleased  to  advise  you of its
commitment to provide  $214,000,000 of the amount of the Facility upon the terms
and subject to the conditions set forth or referred to in this commitment letter
(this "Commitment  Letter") and in the Summary of Terms and Conditions  attached
hereto as Exhibit A (the "Term Sheet").

                  It is agreed that (i) CIBC will act as the sole and  exclusive
administrative agent (the "Administrative Agent") for the Facility and (ii) CIBC
World Markets and CSI will act as co-book managers and co-lead arrangers for the
Facility,  and that each  will,  in such  capacities,  perform  the  duties  and
exercise  the  authorities  customarily  performed  and  exercised by it in such
roles. You agree that no other agents, co-agents or arrangers will be appointed,
no other titles will be awarded and no  compensation  (other than that expressly
contemplated  by the Term Sheet and the Fee Letter  referred  to below)  will be
paid in connection with the Facility unless you and we shall so agree.

                  CIBC World Markets and CSI intend to syndicate the Facility to
a group of financial  institutions (together with CIBC and Chase, the "Lenders")
identified  by CIBC World Markets and CSI in  consultation  with you. CIBC World
Markets and CSI intend to commence  syndication efforts promptly,  and you agree
actively  to  assist  CIBC  World  Markets  and  CSI in  completing  a  mutually
satisfactory   syndication.   Such  assistance  shall  include  (a)  your  using
commercially  reasonable efforts to ensure that the syndication  efforts benefit
materially from the existing lending  relationships of the Borrower and TNP, (b)
direct contact  between  senior  management and advisors of the Borrower and TNP
and the proposed  Lenders,  (c) assistance in the  preparation of a Confidential
Information  Memorandum and other  marketing  materials to be used in connection
with the  syndication  and (d) the hosting,  with CIBC World Markets and CSI, of
one or more meetings of prospective Lenders.

                  CIBC World  Markets  and CSI will  manage  all  aspects of the
syndication,  including  decisions  as to the  selection of  institutions  to be
approached  and when they will be  approached,  when their  commitments  will be
accepted,   which   institutions  will  participate,   the  allocations  of  the
commitments  among the Lenders and the amount and distribution of fees among the
Lenders. To assist CIBC World Markets and CSI in their syndication  efforts, you
agree  promptly  to  prepare  and  provide  to CIBC  World  Markets  and CSI all
information with respect to the Borrower,  the Partnership,  TNP, the Merger and
the other transactions  contemplated hereby, including all financial information
and projections (the "Projections"),  as we may reasonably request in connection
with the arrangement and syndication of the Facility.  You hereby  represent and
covenant that (a) all information other than the Projections (the "Information")
that has been or will be made available to CIBC,  CIBC World Markets,  Chase and
CSI by you  or any of  your  representatives  is or  will  be,  when  furnished,
complete  and correct in all material  respects  and does not or will not,  when
furnished,  contain any untrue  statements of a material fact or omit to state a
material fact necessary to make the statements  contained therein not materially
misleading in light of the  circumstances  under which such  statements are made
and (b) the  Projections  that have been or will be made available to CIBC, CIBC
World Markets,  Chase and CSI by you or any of your representatives have been or
will be prepared in good faith based upon reasonable assumptions. You understand
that in  arranging  and  syndicating  the  Facility  we may use and  rely on the
Information and Projections without independent verification thereof.

                  As consideration for CIBC's and Chase's commitments  hereunder
and CIBC World  Markets' and CSI's  agreement to perform the services  described
herein,  you  agree  to pay to  CIBC,  CIBC  World  Markets,  Chase  and CSI the
nonrefundable  fees set forth in Annex I to the Term Sheet and in the Fee Letter
dated the date hereof and delivered herewith (collectively, the "Fee Letter").

                  CIBC,  CIBC World  Markets,  Chase and CSI shall be  entitled,
after  consultation with you, to change the pricing,  terms and structure of the
Facility if CIBC, CIBC World Markets,  Chase and CSI determine that such changes
are advisable to ensure a successful  syndication of the Facility;  provided the
total amount of the Facility remains unchanged.

                  CIBC's  and  Chase's  commitments  hereunder  and  CIBC  World
Markets'  and CSI's  agreements  to perform the  services  described  herein are
subject to (a) there not occurring or becoming known to us any material  adverse
condition or material  adverse change in or affecting the business,  operations,
property,  condition  (financial  or otherwise) or prospects of the Borrower and
TNP and their  respective  subsidiaries,  taken as a whole, (b) our not becoming
aware after the date hereof of any  information  or other matter  affecting  the
Borrower, the Partnership,  TNP or the transactions contemplated hereby which is
inconsistent in a material and adverse manner with any such information or other
matter disclosed to us prior to the date hereof, (c) our satisfaction that prior
to and  during the  syndication  of the  Facility  there  shall be no  competing
offering,  placement or arrangement of any debt  securities or bank financing by
or on  behalf  of  the  Borrower  or  TNP  or any  affiliate  thereof,  (d)  the
negotiation, execution and delivery on or before the date which is 60 days after
the  date  of  your   acceptance  of  this   Commitment   Letter  of  definitive
documentation  with respect to the  Facility  satisfactory  to CIBC,  CIBC World
Markets,  Chase and CSI and their counsel and (e) the other conditions set forth
or referred to in the Term Sheet. The terms and conditions of CIBC's and Chase's
commitments  hereunder  and of the  Facility  are not limited to those set forth
herein and in the Term Sheet,  provided that any additional  conditions shall be
reasonable and customary for facilities  similar to the Facility.  Those matters
that are not covered by the provisions  hereof nor of the Term Sheet are subject
to the approval and agreement of CIBC, CIBC World Markets, Chase, CSI and you.

                  You agree (a) to indemnify and hold harmless CIBC,  CIBC World
Markets, Chase, CSI, their affiliates and their respective officers,  directors,
employees, advisors, and agents (each, an "indemnified person") from and against
any  and  all  losses,  claims,  damages  and  liabilities  to  which  any  such
indemnified  person may become subject arising out of or in connection with this
Commitment Letter, the Facility,  the use of the proceeds thereof, the Merger or
any related  transaction or any claim,  litigation,  investigation or proceeding
relating to any of the foregoing,  regardless of whether any indemnified  person
is a party thereto, and to reimburse each indemnified person upon demand for any
legal or other expenses  incurred in connection with  investigating or defending
any of the foregoing;  provided that the foregoing indemnity will not, as to any
indemnified person,  apply to losses,  claims,  damages,  liabilities or related
expenses to the extent they are found by a final,  non-appealable  judgment of a
court  to  arise  from  the  willful  misconduct  or  gross  negligence  of such
indemnified  person,  and (b) to reimburse CIBC, CIBC World Markets,  Chase, CSI
and their  affiliates on demand for all  out-of-pocket  expenses  (including due
diligence expenses, syndication expenses, consultant's fees and expenses, travel
expenses, and reasonable fees, charges and disbursements of counsel) incurred in
connection  with the  Facility  and any related  documentation  (including  this
Commitment Letter,  the Term Sheet, the Fee Letter and the definitive  financing
documentation) or the administration, amendment, modification or waiver thereof.
No indemnified person shall be liable for any indirect or consequential  damages
in connection with its activities related to the Facility.

                  You acknowledge that CIBC, CIBC World Markets,  Chase, CSI and
their  affiliates  (the terms "CIBC",  "CIBC World  Markets",  "Chase" and "CSI"
being  understood  to  refer  hereinafter  in this  paragraph  to  include  such
affiliates)  may be providing debt  financing,  equity capital or other services
(including  financial  advisory services) to other companies in respect of which
you may have conflicting  interests regarding the transactions  described herein
and  otherwise.  Neither  CIBC,  CIBC  World  Markets,  Chase  nor CSI  will use
confidential  information  obtained  from  you by  virtue  of  the  transactions
contemplated by this Commitment  Letter or its other  relationships  with you in
connection  with the  performance by CIBC,  CIBC World Markets,  Chase or CSI of
services for other  companies,  and neither CIBC, CIBC World Markets,  Chase nor
CSI will furnish any such information to other  companies.  You also acknowledge
that neither CIBC,  CIBC World Markets,  Chase nor CSI has any obligation to use
in connection with the transactions  contemplated by this Commitment  Letter, or
to furnish to you, confidential information obtained from other companies.

                  This Commitment  Letter shall not be assignable by you without
the prior written  consent of CIBC,  CIBC World Markets,  Chase and CSI (and any
purported  assignment  without such consent shall be null and void), is intended
to be solely for the benefit of the parties hereto and is not intended to confer
any benefits  upon,  or create any rights in favor of, any person other than the
parties hereto. This Commitment Letter may not be amended or waived except by an
instrument in writing  signed by you, CIBC,  CIBC World Markets,  Chase and CSI.
This Commitment  Letter may be executed in any number of  counterparts,  each of
which  shall be an  original,  and all of  which,  when  taken  together,  shall
constitute  one  agreement.  Delivery  of an  executed  signature  page  of this
Commitment Letter by facsimile  transmission shall be effective as delivery of a
manually executed  counterpart hereof. This Commitment Letter and the Fee Letter
are the only  agreements  that have been entered into between  CIBC,  CIBC World
Markets,  Chase,  CSI and you with  respect  to the  Facility  and set forth the
entire understanding of the parties with respect thereto. This Commitment Letter
shall be governed by, and construed in accordance with, the laws of the State of
New York.

                  This   Commitment   Letter   is   delivered   to  you  on  the
understanding  that neither this Commitment  Letter,  the Term Sheet nor the Fee
Letter nor any of their  terms or  substance  shall be  disclosed,  directly  or
indirectly, to any other person except (a) to your officers, agents and advisors
who are directly  involved in the  consideration of this matter or (b) as may be
compelled in a judicial or administrative proceeding or as otherwise required by
law (in which case you agree to inform us promptly thereof) and except that this
Commitment  Letter  and the Term  Sheet (but not the Fee Letter or its terms and
substance) may be disclosed to (x) the officers,  directors and  representatives
of TNP who are directly  involved in the  consideration of this matter,  (y) any
regulatory  commission as necessary in seeking regulatory approval of the Merger
or the  transactions  relating thereto or (z) the shareholders of TNP in a proxy
statement seeking approval for the Merger.

                  The   compensation,    reimbursement,    indemnification   and
confidentiality  provisions  contained herein and in the Fee Letter shall remain
in  full  force  and  effect   regardless   of  whether   definitive   financing
documentation   shall  be  executed  and  delivered  and   notwithstanding   the
termination of this Commitment Letter or CIBC's, CIBC World Markets', Chase's or
CSI's commitment hereunder.

                  If the foregoing  correctly sets forth our  agreement,  please
indicate  your  acceptance of the terms hereof and of the Term Sheet and the Fee
Letter by returning to us executed counterparts hereof and of the Fee Letter not
later than 12:00 p.m.,  New York City time, on May 25, 1999.  CIBC's and Chase's
commitments and CIBC World Markets' and CSI's  agreements  herein will expire at
such time in the event CIBC, CIBC World Markets, Chase and CSI have not received
such  executed   counterparts  in  accordance  with  the  immediately  preceding
sentence.

                                   calculated at the per annum rate set forth on
                                   Annex II on the average daily unused  portion

                                   bear   interest   at  2.00%  above  the  rate

                                   the  basis of a year of 360 days (or  365/366
                                   days,  in the case of ABR Loans the  interest
                                   rate  payable  on which is then  based on the
                                   Prime Rate) for actual days elapsed.

                               FIRST AMENDMENT TO
                          AGREEMENT AND PLAN OF MERGER

         THIS  FIRST   AMENDMENT   TO   AGREEMENT   AND  PLAN  OF  MERGER  (this
"Amendment"),  dated as of  August  9,  1999,  is  entered  into by and among SW
Acquisition, L.P., a Texas limited partnership ("Parent"), ST Acquisition Corp.,
a Texas corporation ("Sub"), and TNP Enterprises, Inc., a Texas corporation (the
"Company").  Capitalized terms used in this Amendment  without  definition shall
have the respective meanings given to them in the Agreement (as defined below).

                                    RECITALS

         WHEREAS,  the  parties  entered  into that  certain  Agreement and Plan
of Merger, dated as of May 24, 1999 (the "Agreement"); and


         WHEREAS,  Parent and the respective  Boards of Directors of the Company
and Sub desire to amend the Agreement in accordance with Section 8.03 thereof by
entering into this Amendment in the manner set forth below.

         NOW,  THEREFORE,  in consideration of the mutual promises and covenants
contained   herein  and  in  the   Agreement,   and  other  good  and   valuable
consideration,  the adequacy of which is hereby acknowledged,  the parties agree
as follows:

         1.       Amendments.

         (a)     Section  2.01(e)(ii)  of  the  Agreement is hereby  amended  by
adding the  following at the end of such section:

         Notwithstanding  the  preceding,  the  Texas-New  Mexico Power  Company
         Thrift Plan for Employees  shall not be terminated but shall be amended
         effective as of the Effective Time to prohibit the issuance or grant by
         the Company or any of its  Subsidiaries  of any  interest in respect of
         the capital stock of the Company or any of its Subsidiaries.

         (b)     Section 6.05(a) of the Agreement is hereby amended and restated
in its entirety as follows:

                           6.05 Employee  Benefit Plans.  (a) From and after the
         Effective Time,  Parent shall cause the Company  Employee Benefit Plans
         in  effect  at the date of this  Agreement  (other  than the  Company's
         Equity  Incentive  Plan and the Company's  Non-Employee  Director Stock
         Plan) to remain in effect until the first  anniversary of the Effective
         Time or, to the extent such Company  Employee Benefit Plans (other than
         the Company's  Equity  Incentive  Plan and the  Company's  Non-Employee
         Director  Stock  Plan)  are not  continued,  Parent  will  cause  to be
         maintained  until such date benefit plans which are no less  favorable,
         in the  aggregate,  to the employees  covered by such Company  Employee
         Benefit Plans,  provided,  however, that nothing contained herein shall
         be  construed  as  requiring  Parent or the  Surviving  Corporation  to
         continue  any  specific  plan or to grant to any  person  any  right to
         acquire any equity securities of Parent,  the Surviving  Corporation or
         any of their respective  Subsidiaries,  or as preventing  Parent or the
         Surviving Corporation from (a) establishing and, if necessary,  seeking
         shareholder  approval to establish,  any other benefit plans in respect
         of all or any of the employees covered by such Company Employee Benefit
         Plans or any other  employees,  or (b) amending  such Company  Employee
         Benefit  Plans  (or  any  replacement  benefit  plans  therefor)  where
         required by applicable  law or where such amendment is with the consent
         of the affected  employees.  From and after the Effective Time,  Parent
         shall honor,  and shall cause its  Subsidiaries to honor, in accordance
         with its  express  terms,  each  then  existing  employment,  change of
         control, severance and termination agreement between the Company or any
         of its  Subsidiaries,  and any  officer,  director  or employee of such
         company,   including  without  limitation  all  legal  and  contractual
         obligations pursuant to outstanding restoration plans, severance plans,
         bonus  deferral  plans,   vested  and  accrued   benefits  and  similar
         employment and benefit arrangements,  policies and agreements that have
         been  disclosed to Parent as of the date hereof and other  obligations,
         if any,  entered into in accordance  with Sections  5.0l(b)(ii)(C)  and
         (H). The officers and directors of the Company and its Subsidiaries are
         intended beneficiaries of this Section 6.05.

         2.       Full Force and Effect.  All other terms and  provisions of the
Agreement not expressly  modified by this Amendment shall  remain in  full force
and effect and are hereby expressly ratified and confirmed.

         3.  Section  Headings,  Construction.  The headings of Sections in this
Amendment are provided for convenience only and will not affect its construction
or  interpretation.  All words used in this Amendment will be construed to be of
such gender or number as the circumstances  require.  Unless otherwise expressly
provided, the word "including" does not limit the preceding words or terms.

         4.       Counterparts.  This Amendment may be executed in counterparts,
each  of  which  shall  b e deemed an original for all purposes and all of which
shall be deemed  collectively  to be one agreement,  but in  making proof hereof
it shall be necessary to exhibit only one such counterpart.

                                    * * * * *
