                  Notes to Consolidated Financial Statements


Note 1.  Interim Financial Statements

   The interim consolidated financial statements of TNP and subsidiaries, and
TNMP and subsidiaries, are unaudited and contain all adjustments (consisting
primarily of normal recurring accruals) necessary for a fair statement of the
results for the interim periods presented.  Results for interim periods are not
necessarily indicative of results to be expected for a full year or for
previously reported periods due in part to seasonal revenue fluctuations.  It is
suggested that these consolidated financial statements be read in conjunction
with the audited consolidated financial statements and notes thereto included in
TNP's and TNMP's 1999 Combined Annual Report on Form 10-K.

     Prior period statements have been reclassified in order to be consistent
with current period presentation.  The reclassification had no effect on net
income or common shareholders equity.

Note 2.  Acquisition

     On March 14, 2000, the process of obtaining needed approvals for the Merger
was completed.  On April 7, 2000, ST Acquisition Corp., a Texas corporation (ST
Corp.) merged with and into TNP, the parent of TNMP.  Upon closing, each
outstanding share of TNP's common stock that was outstanding at the effective
time of the merger was automatically converted into the right to receive $44.00
in cash.  Prior to the merger, TNP common stock was traded on the New York Stock
Exchange.  As a result of the Merger, TNP is no longer publicly held.

     The merger occurred pursuant to an Agreement and Plan of Merger (Merger
Agreement) dated May 24, 1999, between TNP, ST Corp. and SW Acquisition, L.P.
("SW Acquisition"), the parent of ST Corp.  TNP is the surviving corporation in
the Merger.  SW Acquisition now holds all outstanding common stock of TNP.

     SW Acquisition and ST Corp. funded the merger as follows (in millions):

       Sources of funding:
       -------------------
         Equity contribution to ST Corp. by SW Acquisition              $  100.0

         Borrowings from senior secured credit facility by ST Corp.        160.0
         Issuance of senior subordinated notes by ST Corp.                 275.0

                                                                        ========

       Uses of funding:
       ---------------
         Payment of Merger consideration                                $  591.6
         Costs and expenses related to Merger                               48.7
                                                                        --------
           Total                                                        $  640.3
                                                                        ========

     The senior preferred stock was issued in a private placement under a bridge
preferred stock commitment.  Until the bridge preferred stock is replaced with a
permanent issuance of senior preferred stock, it will accrue dividends at a rate
based off of LIBOR, with the initial dividend rate set at 13.28%.  If the senior
preferred stock has not been replaced by July 7, 2000, the dividend rate will
increase by an additional 100 basis points.  Further delays in permanently
placing the stock will cause the dividend rate to increase an additional 50
basis points on October 5, 2000 and January 3, 2001, with the rate being fixed
at 18% beginning April 8, 2001.  TNP intends to replace the bridge preferred
stock with a senior preferred stock that pays an in-kind dividend.  The
borrowings from the senior secured credit facility include a $160 million term
loan due in 2006.  The term loan bears interest at a variable rate that is
currently 9.21%.  The senior secured credit facility is secured by a pledge of
all TNMP common stock held by TNP.  The senior subordinated notes were issued
through a private offering, bear interest at 10.25% per year, and mature in
2010.

     In connection with the Merger, TNMP entered into a Backstop Credit Facility
(Backstop Facility) in the amount of $240 million on April 17, 2000.  The
Backstop Facility will provide financing for TNMP to repurchase up to $100
million of its 9.25% Series U first mortgage bonds and up to $140 million of its
10.75% Series A Secured Debentures.  As required by its first mortgage bond and
secured debenture indentures, TNMP must offer to repurchase this debt at 101
percent of par value due to the change in control of TNP resulting from the
Merger.  TNMP made such an offer in late April 2000, and holders have until May
24, 2000, to respond.  Payment on tendered bonds and debentures shall be made
within five business days of the offer's expiration.

     The Merger is to be accounted for under the purchase method of accounting.
In accordance with the purchase method of accounting, the purchase price will be
allocated to the acquired assets and assumed liabilities based on their fair
values and the unallocated amount will be recorded as goodwill.  The process of
determining the fair value of assets and liabilities is underway, and the final
results will not be completed until certain information about pre-acquisition
contingencies is assessed.  The most significant items to be determined include
the appropriate value to assign to TNP's sole generating plant and the amount of
regulatory assets to be recorded for recovery of stranded costs as permitted by
Texas legislation.

     The following condensed unaudited pro forma consolidated balance sheet
shows the effect of the Merger closing as if it had occurred on March 31, 2000.
The condensed unaudited pro forma consolidated statements of income and loss
show the effects of the Merger closing as if it had occurred on January 1, 2000
and 1999, respectively.  These pro forma financial statements are based on a
preliminary estimate of the fair value of assets acquired and liabilities
assumed in connection with the Merger.  These results are not necessarily
indicative of actual results that would have occurred had the Merger closed at
the beginning of the periods presented.  Further, the pro forma results are not
intended to be a projection of future results of operations.  A substantial
portion of TNMP's earnings occur during the second and third quarters of the
year, which include the periods of peak electricity usage in the TNMP service
territory.

Note 3. Regulatory Matters

     During 1999, legislation was passed in both Texas and New Mexico that
establishes retail competition for generation operations.  Retail competition is
currently scheduled to begin in New Mexico and Texas on January 1, 2001, and
January 1, 2002, respectively.  The legislation in both states contains
provisions that affect TNMP's operations.  The impact of those provisions will
be noted as necessary in the following discussion.

 Texas

     Excess Earnings.  As discussed in TNMP's 1999 Annual Report on Form 10-K,
TNMP has operated since 1998 with an earnings cap that provided for excess
earnings to be used, in part, to recover stranded costs.  During 1998, TNMP's
Transition Plan directed the method for sharing of excess earnings.  In 1999,
legislation was passed in Texas, which also provides for stranded cost recovery
through use of earnings in excess of an allowed rate of return.

     1998 Excess Earnings.  In its original 1998 earnings report filing, TNMP
reported that it had not earned in excess of the 11.25% return on equity
established in the Transition Plan.  On May 3, 2000, the Public Utility
Commission of Texas (PUCT) issued a final order resolving two issues raised by
the PUCT's Office of Regulatory Affairs on August 16, 1999.  The PUCT held in
favor of TNMP that the effects of a 1999 refinancing should not be retroactively
applied to 1998, but should be applied starting with the 1999 earnings report.
However, the PUCT ordered TNMP to defer a $4.8 million purchased power dispute
payment it made in 1998, and to amortize it over a four-year period, beginning
in 1998 and ending in 2001.  Accordingly, in March 2000 TNMP recorded a
regulatory asset of $2.4 million, the unamortized balance of the $4.8 million
payment and a corresponding reduction to purchased power expense.

     Based on the adjustment discussed above, TNMP earned $1.2 million more than
the earnings cap for 1998.  In accordance with the Transition Plan, the excess
earnings will be shared equally between customer refunds and stranded cost
recovery.

                                      -13-
<PAGE>

     1999 Excess Earnings.  On March 30, 2000, TNMP filed its Annual Report
pursuant to (S)39.257 of the Public Utility Regulatory Act.  The Annual Report
details TNMP's calculation of excess earnings under the provisions of the
legislation passed in 1999.  The Annual Report showed that TNMP earned $22.0
million in excess of the 10.53% return on rate base established in the
legislation.  That amount is $1.4 million lower than the $23.4 million TNMP had
accrued for excess earnings as of December 31, 1999.  The difference is
attributable to the amortization of the 1998 purchased power settlement
described above.

     2000 Excess Earnings.  TNMP has recorded estimated excess earnings of $2.0
million for the three months ended March 31, 2000.

     Unbundled Cost of Service Filing.  The legislation requires TNMP to file a
rate case that will set rates for the transmission and distribution company that
will provide regulated services once competition begins in 2002.  On March 31,
2000, TNMP filed its Unbundled Cost of Service Filing (UCOS) with the PUCT.  The
filing proposes tariffs under which Retail Electric Providers (REPs) will be
able to purchase transmission and distribution services after December 31, 2001
in TNMP's service area.  The tariffs are based upon a projected cost of service
of $150.3 million.  The cost of service includes TNMP's projected reasonable and
necessary expenses, and return on its transmission and distribution rate base at
a 9.11% weighted average cost of capital.

     The filing also includes a proposed Competition Transition Charge (CTC), as
required by the legislation.  The CTC is designed to recover stranded costs
related to TNMP's generation assets and purchased power contracts, as determined
by a PUCT-established model.  In its filing, TNMP calculated Economic Cost over
Market (ECOM) in the amount of $194.4 million would remain at January 1, 2002.
In addition, TNMP expects the PUCT to address certain issues related to its
January 2000 Business Separation Plan filing in the UCOS.

     The PUCT has proposed a schedule for TNMP's UCOS that contemplates a
settlement conference in August 2000, hearings in October 2000, if no settlement
is reached, a preliminary decision in February 2001, and final orders in August
2001.

     Fuel Reconciliation.  At March 31, 2000, TNMP had an under-recovered
balance of fuel and the energy-related portion of purchased power costs of $24.3
million.  PUCT rules require TNMP to reconcile its fuel and energy-related
purchased power costs at least every three years.  In June 2000, TNMP plans to
file with the PUCT to recover and reconcile fuel and energy-related purchased
power expenses.  TNMP will request an increase to the fuel factor based on
projected fuel and energy-related purchased power costs.  TNMP will also request
an interim surcharge to begin recovery of TNMP's under recovered costs as of
March 31, 2000.  Management believes the ultimate outcome of this fuel
reconciliation will not have a material adverse effect on TNP's or TNMP's
consolidated financial position.

 New Mexico

     1999 Rate Case.  TNMP and the NMPRC Staff reached a settlement in this
case, which was filed in June 1999, and have submitted the settlement to the
NMPRC for approval.  The settlement calls for a decrease in TNMP's base rates of
$1.8 million, or 6%, effective October 1, 1999.  TNMP has reserved $0.9 million
related to the base rate reductions through March 31, 2000.  TNMP expects the
NMPRC to act on the proposed settlement during the second quarter of 2000.

     Restructuring.  The New Mexico Legislature opened the state's electric
power market to consumer choice with the passage of the Electric Utility
Industry Restructuring Act of 1999 (the Act) in April 1999.  The Act provides
for the phase-in of retail choice beginning January 1, 2001, and guarantees
recovery of at least 50 percent of a utility's stranded costs over a five-year
period.  The Act also requires utilities to disaggregate their regulated
transmission and distribution business activities from their generation
operations, which will be subject to competition.  TNMP is required to file its
plan for complying with the Act by June 1, 2000.

Note 5.  Commitments and Contingencies

 Legal Actions

     Phillips Petroleum.  TNMP is the defendant in a suit styled Phillips
Petroleum Company vs. Texas-New Mexico Power Company, filed on October 1, 1997
and pending in the 149th State District Court of Brazoria County, Texas.  The
suit, which is in the discovery stage, is based on events surrounding an
interruption of electricity to a petroleum refinery and related facilities that
occurred in May 1997.  Phillips Petroleum Company is seeking the recovery of
damages arising from the interruption and in May 1999 demanded payment in the
amount of $47.1 million.  TNMP's tariff approved by the PUCT contains
limitations against recovery of the great majority of Phillip's alleged damages.
The Texas Supreme Court, in another matter, has recently upheld the
enforceability of such tariff limitations in litigation of this type; TNMP
believes the ruling will operate to substantially limit any recovery by Phillips
to the cost of its electrical equipment, in the event that any damages are
awarded in this matter.  Discovery has not sufficiently progressed to quantify
any damages to Phillips' electrical equipment; however, Phillips has previously
reported to the SEC that it incurred costs of approximately $2.0 million in this
interruption.  In May 1999, TNMP filed a Third Party Petition naming Sweeny
Cogeneration Limited Partnership, the operator of cogeneration and related
facilities at the Phillips refinery, as a defendant.  TNMP has previously
charged to earnings the deductible amount of its insurance coverage, $500,000.

     Power Resource Group.  TNMP is a defendant in a suit styled Power Resource
Group, Inc. v. Public Utility Commission of Texas and Texas-New Mexico Power
Company, pending in the 345th District Court of Travis County, Texas. This
lawsuit, which was originally filed on May 21, 1999, appeals the PUCT's
dismissal of a regulatory case that Power Resource Group, Inc. (PR Group) had
filed against TNMP.  PR Group is a developer of electric generating plants that
are intended to be qualifying cogeneration facilities.  This lawsuit and the
regulatory case it appeals both stem from discontinued negotiations for power
supply.  PR Group alleged that TNMP was required to buy power to be generated
from an as-yet-unbuilt cogeneration facility.  TNMP filed its original answer
with the court on June 28, 1999.

     In an amended petition filed January 13, 2000, PR Group asserts a claim of
damages of at least $158,000,000.  It bases its claim on the assertion that it
was damaged when TNMP refused to execute an agreement after the aforementioned
discontinued negotiations, that TNMP profited significantly from PR Group's
work, that TNMP is in error when it relies on a PUCT order dismissing PR Group's
petition before the PUCT on substantially the same facts, and that TNMP
misrepresented that it would enter into a contract with PR Group to purchase
energy and capacity at rates equal to or below TNMP's avoided costs.  TNMP
believes that PR Group's claims are without merit and intends to contest this
claim vigorously.

     TNMP is involved in various claims and other legal proceedings arising in
the ordinary course of business.  In the opinion of management, the ultimate
dispositions of these matters will not have a material adverse effect on TNMP's
and TNP's consolidated financial position or results of operations.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations (MD&A).

     The following discussion should be read in conjunction with the related
interim consolidated financial statements and notes.

Results Of Operations

 Overall Results

     TNP's earnings applicable to common stock were $7.3 million for the quarter
ended March 31, 2000 as compared to $3.1 million for the quarter ended March 31,
1999.  Since the operations of TNMP (the principal subsidiary) currently
represent most of TNP's operations, the following discussion focuses on TNMP's
operations unless noted otherwise.

     Under legislation passed in 1999, TNMP's earnings on its Texas operations
are capped at a 10.53% return on rate base adjusted for discounted rates to
industrial customers, which are expected to be approximately $2.0 million in
2000.  TNMP will apply Texas earnings in excess of the cap to recover its
stranded costs.  During the first quarter of 2000, TNMP recorded pre-tax excess
earnings of $2.0 million ($1.2 million after tax).  That amount included an
adjustment to the excess earnings recorded in 1998 and 1999 due to the
resolution of a purchased power dispute discussed in Note 3 - 1998 Excess
Earnings.

     TNMP's earnings applicable to common stock were $7.8 million for the
quarter ended March 31, 2000 as compared to $3.8 million for the quarter ended
March 31, 1999.  The $4.0 million increase is attributable to the factors listed
below (in millions):

                                      -16-
<PAGE>

     Current quarter base revenue increased $1.5 million, or 2.0%, compared to
the corresponding 1999 period.  The increase resulted from higher weather-
related sales in the residential and commercial classes, higher transmission
revenues, and growth in the number of residential and commercial customers.
These increases were offset in part by a rate reduction in Texas pursuant to the
Transition Plan.

     Transmission revenues increased due to a change in the method of allocating
Texas transmission costs that the PUCT approved as of September 1, 1999.  The
PUCT adopted the new method to comply with the restructuring legislation passed
in 1999 as discussed in Note 3.

     Effective January 1, 2000, TNMP implemented base rate reductions of 3% and
1% for residential and commercial customers, respectively, under the terms of a
Declaratory Order issued by the PUCT on December 6, 1999.  Similar rate
reductions will take effect January 1, 2001.

                           =====      =====        ===

     Current quarter sales of 2,180 GWHs increased by 82 GWHs (or 3.9%) as
compared to the corresponding 1999 period. The increase resulted from higher
off-system sales, higher weather-related sales in the commercial and residential
classes, and growth in the number of commercial and residential customers.
Although weather in the first quarter of 2000 was below normal, it was not as
mild as weather in the first quarter of 1999.

 Operating Expenses

     TNMP incurred operating expenses of $106.5 million in the quarter ended
March 31, 2000, an increase of $3.4 million over the amount incurred during the
corresponding period of 1999.  The increase reflects higher costs for purchased
power, fuel, and other operating expenses partially offset by lower transmission
expenses and lower charges for recovery of stranded plant.

 Purchased Power and Fuel Expenses

fuel expenses (in thousands).

     In the first quarter of 2000, purchased power and fuel expenses increased
$2.2 million from the level incurred during the first quarter of 1999.  Pass-
through expenses increased $4.9 million, reflecting increased purchases caused
by higher sales and price increases in New Mexico.  Non pass-through expenses
decreased $2.7 million due to the deferral of a 1998 payment made to resolve a
billing dispute as described in Note 3 - 1998 Excess Earnings.

                                      -17-
<PAGE>

 Transmission Expenses

     Transmission expenses decreased by $1.1 million in the first quarter of
2000 compared to the corresponding period in 1999, due to the change in cost
allocation described in "Operating Revenues," above.

 Other Operating Expenses

     Other operating expenses for the current quarter were $1.7 million higher
than in the same quarter of 1999.  This increase is primarily due to higher
payroll costs and a payment to the Texas Department of Housing for programs to
assist low-income customers.

 Charge for Recovery of Stranded Plant

     Charge for recovery of stranded plant decreased $2.1 million in the first
quarter of 2000 compared to the same period in 1999.  During the first quarter
of 2000, TNMP recorded pre-tax excess earnings of $1.6 million.  In the first
quarter of 1999, TNMP recorded $3.7 million of additional depreciation under the
Transition Plan.

 Interest Expense

     Interest charges decreased by $1.0 million due to TNMP's January 1999
issuance of $175 million of 6.25% senior notes, which replaced $130 million of
12.5% secured debentures, and due to reduced debt levels of the credit
facilities, and lower amortization of debt related expenses.

Financial Condition

 TNMP Liquidity

     The main sources of liquidity for TNMP are cash flow from operations and
borrowings from its credit facility.  TNMP's cash flow from operations was $6.5
million lower for the first quarter of 2000 as compared to the first quarter of
1999 due to lower receipts from customers, resulting from base rate reductions
in Texas, and the timing of the first interest payment on TNMP's 6.25% senior
notes.

     As discussed in Note 2, due to the change in control of TNMP resulting from
the Merger, TNMP has made a tender offer to purchase its Series U first mortgage
bonds and Series A Secured Debentures at a price of 101% of par.  TNMP has the
ability to borrow up to $240 million from a backstop credit facility to
refinance any debt that must be redeemed as a result of this tender offer.

     TNMP has $100 million of 9.25% Series U first mortgage bonds that mature in
September 2000.  To the extent that the bonds are not purchased under the tender
offer described above, TNMP expects to establish a new credit facility in an
amount sufficient to refinance the bonds.

     TNMP has sufficient liquidity to satisfy the possibility of any known
contingencies.  Management believes cash flow from operations, the backstop
credit facility described above and periodic borrowings under its revolving
credit facility should be sufficient to meet working capital requirements at
least through 2000.

 TNP Liquidity

     TNP's main sources of liquidity, and its ability to service the debt issued
to finance the Merger, depend primarily on the earnings of TNMP and the
distribution of those earnings in the form of cash dividends, as well as tax
payments from TNMP due under a tax sharing agreement between TNP and TNMP.  TNP
has a $25 million revolving credit facility that will be used to provide working
capital and meet other requirements.  The revolving credit facility was put in
place at the time of the Merger.  As of the date of the Merger, TNP had not
borrowed against the revolving credit facility, and the entire $25 million was
available to TNP.

     Cash dividends from TNMP to TNP are limited by restrictions included in
TNMP's debt indentures and bank agreements.  In addition, the regulatory orders
from the PUCT and the NMPRC approving the Merger contain additional restrictions
on TNMP's ability to pay cash dividends to TNP.

     During the first quarter of 2000, TNP's cash flow from operations was $1.7
million lower than in the first quarter of 1999 due to TNMP's lower cash flow
from operations as discussed above, offset by reduced expenditures for non-
regulated activities.

                                      -18-

     Management believes that dividends from TNMP, payments from TNMP under the

facility should be sufficient to meet TNP's working capital requirements at
least through 2000.

Statement Regarding Forward Looking Information

     The discussions in this document that are not historical facts, including,
but not limited to, the continued application of regulatory accounting
principles, future cash flows and the potential recovery of stranded costs, are
based upon current expectations.  Actual results may differ materially.  Among
the facts that could cause the results to differ materially from expectations
are the following: our ability to adapt to open market competition enacted by
our legislators and regulators; the effects of accounting pronouncements that
may be issued periodically; changes in regulations affecting TNP's and TNMP's
businesses; insurance coverage available for claims made in litigation; the
effect of a Texas Supreme Court decision on the limitations of any actual
damages awarded in currently ongoing litigation; future acquisitions or
strategic partnerships; general business and economic conditions, and price
fluctuations in the electric power market; our ability to market preferred stock
to replace the bridge preferred stock; and other factors described from time to
time in TNP's and TNMP's reports filed with the Securities and Exchange
Commission.  TNP and TNMP wish to caution readers not to place undue reliance on
any such forward looking statements, which are made pursuant to the Private
Securities Litigation Reform Act of 1995 and, as such, speak only as of the date
made.
