  Southwest Royalties, Inc., a Delaware corporation ("Southwest" or the
"Issuer"), and Southwest Royalties Holdings, Inc., a Delaware corporation
("SRH"), and the parent of the Issuer, hereby offer, upon the terms and
conditions set forth in this Prospectus and the accompanying letter of
transmittal (the "Letter of Transmittal," and together with this Prospectus,
the "Exchange Offer"), to exchange $1,000 principal amount of its 10 1/2%
Series B Senior Notes due 2004 of the Issuer and which are fully and
unconditionally guaranteed on a senior basis by SRH (the "Exchange Notes"),
which have been registered under the Securities Act of 1933, as amended (the
"Securities Act"), pursuant to a Registration Statement (as defined) of which
this Prospectus constitutes a part, for each $1,000 principal amount of its
outstanding 10 1/2% Series A Senior Notes due 2004 of the Issuer and which are
fully and unconditionally guaranteed on a senior basis by SRH (the "Old
Notes"), of which $200,000,000 principal amount is outstanding. The form and
terms of the Exchange Notes are identical in all material respects to the form
and terms of the Old Notes except for certain transfer restrictions and
registration rights relating to the Old Notes. The Exchange Notes will
evidence the same debt as the Old Notes and will be issued under and be
entitled to the benefits of the Indenture (as defined). The Exchange Notes and
the Old Notes are collectively referred to herein as the "Notes."
 
  The Notes are senior obligations of the Issuer, ranking pari passu in right
of payment with all existing and future senior Indebtedness (as defined) and
senior to all existing or future Subordinated Indebtedness (as defined) of the
Issuer. The Notes are fully and unconditionally guaranteed by SRH (the "Parent
Guarantee") on a senior basis. The Parent Guarantee is secured by a pledge of
the common stock of Midland Red Oak Realty, Inc. and Sierra Well Service, Inc.
owned directly by SRH. Such collateral may be released under certain
circumstances. See "Description of Notes--Collateral."
 
  The Notes, the Guarantee and any Subsidiary Guarantee will be effectively
subordinated to: (i) the Southwest Credit Facility, which is secured by
substantially all of Southwest's oil and gas properties, and (ii) all other
secured indebtedness of SRH and Southwest. At September 30, 1997, on a pro
forma basis after giving effect to the Offering and the application of the
proceeds therefrom, SRH and Southwest would have had $88.2 million in
indebtedness that ranks pari passu and senior to the Exchange Notes. The Notes
are redeemable at the option of the Issuer at any time on or after October 15,
2001. In addition, if SRH or the Issuer consummate a Public Equity Offering on
or before October 15, 2000 the Issuer may use a portion of the proceeds to
redeem up to $70,000,000 aggregate principal amount of the Notes

THESE SECURITIES HAVE  NOT BEEN APPROVED OR DISAPPROVED BY  THE SECURITIES AND
 EXCHANGE  COMMISSION  OR  ANY  STATE   SECURITIES  COMMISSION  NOR  HAS  THE
 SECURITIES  AND  EXCHANGE  COMMISSION  OR ANY  STATE  SECURITIES  COMMISSION
  PASSED  UPON   THE   ACCURACY  OR   ADEQUACY  OF   THIS   PROSPECTUS.  ANY
  REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
                The date of this Prospectus is February 9, 1998

  The Issuer and SRH will accept for exchange any and all Old Notes that are
validly tendered on or prior to 5:00 p.m., New York City time, on the date the
Exchange Offer expires, which will be 30 days after the effective date of the
Registration Statement, unless the Exchange Offer is extended. See "The
Exchange Offer--Expiration Date; Extensions; Amendments." Tenders of Old Notes
may be withdrawn at any time prior to 5:00 p.m., New York City time, on the
business day prior to the Expiration Date (as defined), unless previously
accepted for exchange. The Exchange Offer is not conditioned upon any minimum
principal amount of Old Notes being tendered for exchange. However, the
Exchange Offer is subject to certain conditions which may be waived by the
Issuer and SRH and to the terms and provisions of the Registration Rights
Agreement (as defined). Old Notes may be tendered only in denominations of
$1,000 principal amount and integral multiples thereof. The Issuer and SRH
have agreed to pay the expenses of the Exchange Offer. See "Exchange Offer."
 
  The Exchange Notes will bear interest at the rate of 10 1/2% per annum,
payable semi-annually on April 15 and October 15 of each year, commencing on
April 15, 1998. Interest on the Exchange Notes will accrue from (A) the later
of (i) the last interest payment date on which interest was paid on the Notes
surrendered in exchange therefor; or (ii) if the Notes are surrendered for
exchange on a date in a period which includes the record date for an interest
payment date to occur on or after the date of such exchange and as to which
interest will be paid, the date of such interest payment date or (B) if no
interest has been paid on the Notes, from the date of the original issuance of
the Notes, October 14, 1997. Interest on the Old Notes accepted for exchange
will cease to accrue upon issuance of the Exchange Notes.
 
  The Old Notes were sold by the Issuer and SRH on October 14, 1997 to the
Initial Purchasers (as defined) in a transaction not registered under the
Securities Act in reliance upon Section 4(2) of the Securities Act. The Old
Notes were thereupon offered and sold by the Initial Purchasers only to
"qualified institutional buyers" (as defined in Rule 144A under the Securities
Act). Accordingly, the Old Notes may not be offered, resold or otherwise
transferred unless registered under the Securities Act or unless an applicable
exemption from the registration requirements of the Securities Act is
available. The Exchange Notes are being offered hereunder in order to satisfy
the obligations of the Issuer and SRH under the Registration Rights Agreement
entered into with the Initial Purchasers in connection with the offering of
the Old Notes. See "Exchange Offer" and "Exchange and Registration Rights
Agreement."
 
  Based on no-action letters issued by the staff of the Securities and
Exchange Commission (the "Commission" or "SEC") to third parties, including
EXXON CAPITAL HOLDINGS CORPORATION, SEC No-action Letter (available April 13,
1989), MORGAN STANLEY & CO. INC., SEC No-action Letter (available June 5,
1991) (the "Morgan Stanley Letter") and MARY KAY COSMETICS, INC., SEC No-
action Letter (available June 5, 1991), the Issuer and SRH believe that the
Exchange Notes issued pursuant to the Exchange Offer maybe offered for resale,
resold and otherwise transferred by the respective holders thereof (other than
a "Restricted Holder," being (i) a broker-dealer who purchased Old Notes
exchanged for such Exchange Notes directly from the Issuer and SRH to resell
pursuant to Rule 144A or any other available exemption under the Securities
Act or (ii) a person that is an affiliate of the Issuer and SRH within the
meaning of Rule 405 under the Securities Act), without compliance with the
registration and prospectus delivery provisions of the Securities Act,
provided that such Exchange Notes are acquired in the ordinary course of such
holder's business and such holder is not participating in, and has no
arrangement with any person to participate in, the distribution (within the
meaning of the Securities Act) of such Exchange Notes. Eligible holders
wishing to accept the Exchange Offer must represent to the Issuer and SRH that
such conditions have been met. Holders who tender Old Notes in the Exchange
Offer with the intention to participate in the distribution of the Exchange
Notes may not rely upon the Morgan Stanley Letter or similar no-action
letters. See "Exchange Offer." Each broker-dealer that receives Exchange Notes
for its own account pursuant to the Exchange Offer must acknowledge that it
will deliver a prospectus in connection with any resale of such Exchange
Notes. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act. This Prospectus,
as it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of Exchange Notes received in
exchange for Old Notes where such Exchange Notes were acquired by such broker-
dealer as a result
 
                                       2
<PAGE>
 
of market-making activities or other trading activities. The Issuer and SRH
have agreed that, starting on the Expiration Date and ending on the close of
the business 180 days after the Expiration Date, it will make this Prospectus
available to any broker-dealer for use in connection with any such resale. See
"Plan of Distribution." A broker-dealer which delivers such a prospectus to
purchasers in connection with such resales will be subject to certain of the
civil liability provisions under the Securities Act and will be bound by the
provisions of the Registration Rights Agreement (including certain
indemnification rights and obligations).
 
  Neither the Issuer nor SRH will receive any proceeds from the Exchange
Offer.
 
  The Exchange Notes will constitute a new issue of securities with no
established trading market, and there can be no assurance as to the liquidity
of any markets that may develop for the Exchange Notes or as to the ability of
the holders of Exchange Notes to sell their Exchange Notes or as to or the
price at which the holders of Exchange Notes would be able to sell their
Exchange Notes. Future trading prices of the Exchange Notes will depend on
many factors, including, among others, prevailing interest rates, the
Company's operating results and the market for similar securities. The Issuer
and SRH do not intend to apply for listing of the Exchange Notes on any
securities exchange. Jefferies & Company, Inc., Banc One Capital Corporation,
and Paribas Corporation (the "Initial Purchasers") have informed the Company
that they currently intend to make a market for the Exchange Notes. However,
they are not so obligated, and any such market making may be discontinued at
any time without notice. Accordingly, no assurance can be given that an active
public or other market will develop for the Exchange Notes or as to the
liquidity of or the trading market for the Exchange Notes.
 
  THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE ISSUER OR SRH ACCEPT
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF OLD NOTES IN ANY JURISDICTION IN
WHICH THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE
WITH THE SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.
 
                             AVAILABLE INFORMATION
 
  Neither the Issuer nor SRH is subject to the informational requirements of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Pursuant
to the Indenture, the Issuer and SRH have agreed to provide to the holders
annual reports and the information, documents and other reports otherwise
required pursuant to Section 13 of the Exchange Act. While any Old Notes
remain outstanding, the Issuer and SRH will make available, upon request, to
any holder and any prospective purchaser of Old Notes, the information

period in which the Issuer and SRH are not subject to Section 13 or 15(d) of
the Exchange Act. Any such request should be directed to the Secretary of the
Issuer at 407 North Big Spring, Suite 300, Midland, Texas, 79701; (915) 686-

THE COMPANY
 
  The Company is an independent oil and gas company engaged in the acquisition,
development and production of oil and gas properties, primarily in the Permian
Basin of West Texas and southeastern New Mexico, through its wholly-owned
subsidiary, Southwest. Since 1983, the Company has grown primarily through
selective acquisitions of producing oil and gas properties, completing over
$320 million in acquisitions, both directly and through the oil and gas
partnerships it manages. Consistent with this strategy, the Company recently
purchased additional producing oil and gas properties in the Permian Basin from
a major oil company for approximately $72.3 million, (the "Oil and Gas
Properties Acquisition"). The Company also participates in the well servicing
industry through its affiliate, Sierra, and owns and manages real estate
properties through its subsidiary, Red Oak.
 
  The Company pursues a strategy of acquiring long-life, producing oil and gas
properties, which offer current cash flow, significant development potential
and opportunities to reduce operating and administrative costs. Many of the
Company's previous acquisitions were completed during periods of relatively low
oil and gas prices, and the Company generally deferred development of such
acquired properties to invest available capital in additional acquisitions. Due
to increased oil and gas prices and improved availability of capital, the
Company has increased its oil and gas development activities. The Company plans
to increase capital spending on development and exploitation opportunities.
 
  At June 30, 1997, on a pro forma basis, the Company owned interests in
approximately 2.6 million gross leasehold acres, approximately 75% of which
were classified as developed. At such date, the Company's estimated net proved
reserves, on a pro forma basis, would have been 32.5 MMBbls of oil and 75.3 Bcf
of natural gas, or 45.0 MMBoe. The Company's properties are located primarily
in the Permian Basin and generally have well-established production histories
with a pro forma reserve life of approximately 15 years. At June 30, 1997, PV-
10 Value of the Company's pro forma oil and gas reserves would have been $214.5
million.
 
  The Company's development projects generally involve moderate drilling and
completion costs as they are located primarily in shallow to intermediate
depth, normally pressured reservoirs. Additionally, many of these projects
contain multiple horizons that are potentially productive, thereby further
reducing development drilling risk. The Company has identified over 500
recompletion and development opportunities on its properties, including the
properties acquired in the Oil and Gas Properties Acquisition. For the nine
months ended September 30, 1997, Southwest has spent approximately $27 million
in the aggregate for oil and gas acquisition, development and exploration
activities and has budgeted additional capital spending, of approximately $45
million for the remainder of 1997 and 1998, principally to complete over 190
planned development drilling and recompletion projects. The $45 million
budgeted for capital spending is in addition to the $72.3 million purchase
price for the Oil and Gas Properties Acquisition completed October 14, 1997.
The Company anticipates that its development activities, when combined with new
seismic and other data, will result in the identification of additional
development drilling prospects and proved reserves.
 
                                       5
<PAGE>
 
  The Company engages in the well servicing business through Sierra, in which
SRH directly owns approximately 26% of the common stock. Southwest is also the
general partner and indirectly owns approximately 10% of Sierra as a 15%
interest holder in two partnerships which own approximately 64% of Sierra.
Sierra, which was formed in 1992, provides a broad range of well services to
oil and gas companies, including workover rig services, liquids handling, fresh
and/or brine water supply and disposal and other services. Since January 1996,
Sierra has purchased 17 well servicing companies for a cost of $58.9 million.
In total, these acquisitions increased the equipment fleet to 84 workover rigs.
Management believes that Sierra is the fourth largest land-based well servicing
company in the United States.
 
  Red Oak, an 82%-owned subsidiary of SRH, on a pro forma basis, owns and
manages retail shopping centers and office buildings in Texas, Oklahoma and
Arizona. Since December 1993, Red Oak has acquired 17 properties for
approximately $82.8 million.
 
CERTAIN RISK FACTORS
 
  The following Risk Factors should be considered by prospective purchasers in
evaluating an investment in the Notes. This discussion of Certain Risk Factors
is a partial listing and a summary and is qualified in its entirety by the more
detailed discussion of Risk Factors found elsewhere in this Prospectus.
 
 .  The Company's level of indebtedness may limit its ability to borrow
   additional funds and react to changing business conditions.
 
 .  Upon a Change in Control, each holder of a Note may require the Company to
   repurchase all or a portion of the Note and the Company may not have the
   financial resources necessary to meet such obligations.
 
 .  In the event of a default, the Trustee may not be able to foreclose on or
   dispose of the Collateral without substantial delays and the resulting
   proceeds may not be sufficient to pay all amounts owned to holders of Notes.
 
 .  Under certain circumstances, a court could rule that the direct obligations
   of a Subsidiary Guarantor are superior to its obligations under the
   Subsidiary Guarantee.
 
 .  The Old Notes and the Exchange Notes are both new securities for which there
   is no active trading market. No assurance can be given as to the liquidity
   of the trading market for the Notes. The Old Notes are subject to certain
   transfer restrictions.
 
 .  Mr. Wommack, the Chairman of the Board, President and Chief Executive
   Officer of SRH and Southwest, has the ability to elect all of the directors
   of SRH and Southwest and, directly and indirectly, influence all decisions
   made by SRH and Southwest.
 
 .  Southwest's revenues are highly dependent on the volatile oil and natural
   gas markets.
 
 .  There can be no assurance that the Company will be able to continue its
   current acquisition strategy. There can be no assurance that Southwest will
   be able to find and acquire additional oil and natural gas reserves or have
   the funds to finance planned capital expenditures.
 
 .  The oil and natural gas business involves a variety of operating risks which
   could result in substantial losses to Southwest and not all such risks are
   insurable.

STRATEGY
 
  The Company's objective is to increase its revenues, cash flow, earnings and
assets through a balanced growth strategy of acquisition, development and
exploitation of oil and gas properties, and through its
investments in the well servicing and real estate businesses.
 
  Complete Selective Oil and Gas Acquisitions. The Company seeks to acquire
producing oil and gas properties that provide opportunities for the addition of
reserves, production and cash flow through operational improvements, production
enhancement and additional development. The Company believes these criteria are
met in the Permian Basin due to the region's long history of production and
multiple producing oil and gas horizons. The Company has acquired over $320
million of oil and gas properties since inception, both directly and through
the oil and gas partnerships it manages. Management believes that acquisition
opportunities will continue to be available in the Permian Basin.
 
  Develop and Exploit Existing Oil and Gas Properties. The Company has acquired
a diversified portfolio of oil and gas properties that contains numerous
identified development opportunities. The Company believes that current oil and
gas prices, combined with technical and operating advances, have improved the
attractiveness of accelerated development of these properties. The Company
plans to significantly increase its capital spending during 1997 and 1998 to
pursue these opportunities, which consist principally of infill drilling,
recompletions, enhanced recovery operations and workover opportunities. The
Company is pursuing these projects to increase cash flow and to identify
additional reserves and development projects.
 
  Maintain Geographic Focus. The Company concentrates its oil and gas
activities in the Permian Basin, with properties in this region representing
over 90% of the Company's pro forma PV-10 Value at June 30, 1997. The Company
believes that its long-life oil and gas properties and large inventory of
development projects in the Permian Basin, coupled with region-specific
geological, engineering and production experience, provide it with focused
operations. Company-operated properties comprised approximately 60% of its pro
forma PV-10 Value at June 30, 1997, allowing substantial control over the
incurrence and timing of capital and operating expenditures.
 
  Selectively Grow Well Servicing and Real Estate Businesses. The Company plans
to continue the expansion of its well servicing and real estate businesses,
primarily in the southwestern United States. The Company expects that Sierra's
and Red Oak's active management practices will lead to consolidation benefits,
cost savings, more efficient utilization and improved cash flow, thereby
enhancing the return on capital invested.

                                THE TRANSACTIONS
 
  In conjunction with the Private Placement, the Company completed certain
acquisition and financing transactions (the "Transactions") to provide
additional capital for oil and gas development activities and acquisitions by
Southwest, to finance acquisitions by Sierra and Red Oak and to provide the
Company with additional financing and operating flexibility. The Transactions
are summarized below:
 
  Oil and Gas Properties Acquisition. On October 14, 1997, the Company acquired
various working interests in 431 producing oil and gas wells, located in seven
oil and gas fields in the Permian Basin of West Texas and southeastern New
Mexico. The Company operates 133 of these wells. The purchase price for the Oil
and Gas Properties Acquisition was $72.3 million. The Oil and Gas Properties
Acquisition added approximately 14.0 MMBoe of estimated net proved reserves, as
of June 30, 1997. These properties complement the Company's existing proved
reserve base with an average reserve life of approximately 15 years and over
130 identified development opportunities. The Company believes that it has
significant opportunities to improve production and cash flow from these
properties through additional development, reconfiguration of operations and
reduction of operating and administrative costs. Southwest also amended its $75
million revolving credit facility (the "Southwest Credit Facility") resulting
in unutilized availability of $40 million.
   
  Sierra Acquisitions. Since January 1996, Sierra has acquired 17 Texas and New
Mexico well servicing companies and equipment for a total cost of $58.9
million. In total, these acquisitions added 64 workover rigs, 134 vaccum and
transport trucks, 279 frac and test tanks, 32 brine and/or fresh water stations
and nine injection wells and significantly increased the size and scope of
Sierra's well servicing business. Sierra financed these acquisitions with
proceeds from the sale of Sierra common stock (the "Sierra Equity Sale") and
borrowings from an institutional lender (the "Sierra Acquisition Facility").
The Sierra Equity Sale resulted in a reduction of SRH's direct ownership of
Sierra to approximately 26%.     
 
  Red Oak Acquisitions. Red Oak recently acquired four shopping centers and two
office buildings in Texas and Oklahoma for a total cost of $40.7 million. These
acquisitions expanded Red Oak's commercial real estate portfolio to 14 shopping
centers and three office buildings. Red Oak financed the acquisitions with $10
million in equity proceeds received from SRH and with certain mortgage
facilities (the "Red Oak Acquisition Facilities").
 
                               PRIVATE PLACEMENT
 
  On October 14, 1997 Southwest completed a $200 million private placement sale
of the Old Notes to the Initial Purchasers (the "Private Placement"). Thereupon
the Old Notes were offered and sold by the Initial Purchasers only to qualified
institutional buyers. The net proceeds from the Private Placement were
approximately $190 million. The Issuer used the net proceeds primarily to (i)
fund the Oil and Gas Properties Acquisition (net of deposits paid), (ii) repay
substantially all indebtedness outstanding under Southwest's bank credit
facility and its reserve-based loan facilities, (iii) fund a $10 million equity
investment by SRH in Red Oak through a dividend in that amount from the Issuer
to SRH, (iv) make a general partner capital contribution to Partners III of
approximately $1.7 million, which funds were immediately invested in Sierra
common stock, and (v) provide additional working capital for general corporate

                                  THE OFFERING
 
  The Exchange Offer relates to the exchange of up to $200,000,000 principal
amount of Exchange Notes for up to $200,000,000 principal amount of the Old
Notes. The form and terms of the Exchange Notes are identical in all material
respects to the form and terms of the Old Notes except that the Exchange Notes
have been registered under the Securities Act and will not contain certain
transfer restrictions and hence are not entitled to the benefits of the
Registration Rights Agreement relating to the contingent increases in the
interest rate provided for pursuant thereto. See "Exchange Offer" and "Exchange
and Registration Rights Agreement." The Exchange Notes will evidence the same
debt as the Old Notes and will be issued under and be entitled to the benefits
of the Indenture governing the Old Notes. See "Description of Notes."
 
Exchange Offer............  Each $1,000 principal amount of Exchange Note will
                            be issued in exchange for each $1,000 principal
                            amount of outstanding Old Notes. As of the date
                            hereof, $200,000,000 principal amount of Old Notes
                            are issued and outstanding. The Issuer will issue
                            the Exchange Notes to tendering holders of Old
                            Notes on or promptly after the Expiration Date.
 
Resale....................  The Company believes that the Exchange Notes issued
                            in the Exchange Offer generally will be freely
                            transferable by the holders thereof without
                            registration or any prospectus delivery requirement
                            under the Securities Act, except for certain
                            Restricted Holders who may be required to deliver
                            copies of this Prospectus in connection with any
                            resale of the Exchange Notes. See "Exchange Offer"
                            and "Plan of Distribution."
     
Expiration Date...........  5:00 p.m., New York City time, 30 days after the   
                            effective date of the Registration Statement,      
                            unless the Exchange Offer is extended, in which    
                            case the term "Expiration Date" means the latest   
                            date to which the Exchange Offer is extended. See  
                            "Exchange Offer--Expiration Date; Extensions;      
                            Amendments."                                        

Interest on the Notes.....  The Exchange Notes will bear interest at the rate
                            of 10 1/2% per annum, payable semi-annually on
                            April 15 and October 15 of each year, commencing on
                            April 15, 1998. Interest on the Exchange Notes will
                            accrue from (A) the later of (i) the last interest
                            payment date on which interest was paid on the
                            Notes surrendered in exchange therefor; or (ii) if
                            the Notes are surrendered for exchange on a date in
                            a period which includes the record date for an
                            interest payment date to occur on or after the date
                            of such exchange and as to which interest will be
                            paid, the date of such interest payment date or (B)
                            if no interest has been paid on the Notes, from the
                            date or the original issuance of the Notes, October
                            14, 1997. Interest on the Old Notes accepted for
                            exchange will cease to accrue upon issuance of the
                            Exchange Notes. See "Exchange Offer--Interest on
                            the Exchange Notes."

                            to make a registered exchange offer (the "Exchange
                            Offer") pursuant to which holders of the Old Notes
                            will have the opportunity to exchange their Old

                            (the "Exchange Notes") that are identical in all
                            material respects to the Notes and that may be
                            offered and sold by the holders without
                            restrictions or limitations under the Securities
                            Act or (ii) under certain circumstances, to effect
                            a shelf registration of the Old Notes (the "Shelf
                            Registration Statement") that would include a
                            prospectus under which holders would be free to
                            offer and sell their Notes from time to time. The
                            Issuer and SRH have agreed to use their best
                            efforts to file with the Commission a registration
                            statement relating to the Exchange Offer (the
                            "Exchange Offer Registration Statement") or the
                            Shelf Registration Statement within 60 days after
                            the date of issuance of the Notes (the "Issue
                            Date"), and to use their best efforts to cause such
                            registration statement to be declared effective by
                            the Commission within 120 days after the Issue Date
                            and, in the case of the Shelf Registration
                            Statement, to cause such to remain effective until
                            the second anniversary after the Issue Date. The
                            interest rate on the Notes is subject to increase
                            under certain circumstances if the Issuer and SRH
                            are not in compliance with their obligations under
                            the Registration Rights Agreement. See "Exchange
                            and Registration Rights Agreement."
 
Transfer Restrictions;
Trading Market............  The Old Notes have not previously been registered  
                            under the Securities Act and are subject to        
                            restrictions on transferability and resale. See    
                            "Notice to Investors." The Notes are newly issued  
                            securities for which there is currently no         
                            established market. The Exchange Notes will        
                            generally be freely transferable (subject to the   
                            restrictions discussed elsewhere herein) but will  
                            be new securities for which there will not         
                            initially be a market. Accordingly, there can be no
                            assurance as to the development or liquidity of any
                            market for the Old Notes or the Exchange Notes. The
                            Initial Purchasers have advised the Issuer that    
                            they currently intend to make a market in the Old  
                            Notes and the Exchange Notes. However, the Initial 
                            Purchasers are not obligated to do so, and any     
                            market making with respect to the Old Notes or the 
                            Exchange Notes may be discontinued at any time     
                            without notice.                                     
                            
PORTAL Listing............  The Old Notes sold to QIBs are eligible for trading
                            in the PORTAL market.

    September 30, 1996 and September 30, 1997, respectively, and $9,908,000 and
    $11,680,000 for the pro forma periods ended December 31, 1996 and September
    30, 1997, respectively. For purposes of computing the ratio of earnings to
    fixed charges, earnings are computed as income (loss) before extraordinary
    item plus minority interest in subsidiaries and income taxes, plus fixed
    charges. Fixed charges consist of interest expense and an estimated portion
    of rentals representing interest costs.
(4) Adjusted EBITDA (as used herein) is calculated based on the Indenture,
    which requires EBITDA to be calculated by adding the net income (loss) of
    SRH (as defined on page 5 of this Prospectus) and its Restricted
    Subsidiaries, excluding the net income (loss) of any Unrestricted
    Subsidiary, to minority interest in subsidiaries, income tax benefit
    (provision) and depreciation, depletion and amortization of SRH and
    interest expense of SRH and its Restricted Subsidiaries. Specifically, net
    income (loss), income tax benefit (expense), interest expense and
    depreciation, depletion and amortization of Red Oak is excluded from the
    calculation of Adjusted EBITDA, as Red Oak is an Unrestricted Subsidiary.
    EBITDA is used because the Company believes it is commonly used by debt
    holders and financial statement users as a measurement to determine the
    ability of an entity to meet its interest obligations. EBITDA is not a
    measurement presented in accordance with generally accepted accounting
    principles ("GAAP") and is not intended to be used in lieu of GAAP
    presentation of results of operations and cash provided by operating
    activities.
(5) Adjusted EBITDA to Interest (as used herein) is the ratio of Adjusted
    EBITDA to interest on the Notes plus interest on any other debt of SRH and
    any Restricted Subsidiary.
(6) Pro forma to reflect the Offering and the Transactions as if they had
    occurred on September 30, 1997.
(7) ACNTA means Adjusted Consolidated Net Tangible Assets, as defined in the
    Indenture (see "Description of Notes--Certain Definitions"). In accordance
    with the Indenture, ACNTA is calculated using oil and gas prices utilized
    in the Company's year end reserve report. Indebtedness (as used herein)
    means Indebtedness of SRH and all Restricted Sibsidiaries, which, on a pro
    forma basis as of September 30, 1997, would have been $199.9 million.

(2) PV-10 Value represents the present value of estimated future net revenues
    before income tax discounted at 10% using prices in effect at the end of
    the respective periods presented and including the effects of hedging
    activities. In accordance with applicable requirements of the Commission,
    estimates of Southwest's proved reserves and future net revenues are made
    using oil and natural gas sales prices estimated to be in effect as of the
    date of such reserve estimates and are held constant throughout the life of
    the properties (except to the extent a contract specifically provides for
    escalation). The average prices used in calculating PV-10 Value as of June
    30, 1997 were $17.00 per Bbl of oil and $2.16 per Mcf of natural gas,
    compared to average prices used as of December 31, 1996 of $23.89 per Bbl
    of oil and $3.67 per Mcf of natural gas. The average prices used in
    calculating the pro forma PV-10 Value as of June 30, 1997 were $17.34 per
    Bbl of oil and $2.16 per Mcf of natural gas.
   
(3) Discounted future cash flows, including taxes, are not intended to
    represent estimates of the fair value of oil and gas properties. Estimates
    of fair value should also consider probable reserves, anticipated future
    oil and gas prices, interest rates, changes in development and production
    costs and production costs and risks associated with future production.
    Because of these considerations, any estimate of fair value is necessarily
    subjective and imprecise.

                          FORWARD-LOOKING STATEMENTS
 
  This Prospectus includes "forward-looking statements" within the meaning of
Section 27A of the Securities Act and Section 21E of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"). All statements other than
statements of historical facts included in this Prospectus, including, without
limitation, statements under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business" regarding planned capital expenditures, increases
in oil and gas production, the number of anticipated wells to be drilled in
1997 and 1998, the Company's financial position, business strategies and other
plans and objectives for future operations, are forward-looking statements.
Although the Company believes that the expectations reflected in such forward-
looking statements are reasonable, it can give no assurance that such
expectations will prove to have been correct. There are numerous uncertainties
inherent in estimating quantities of proved oil and natural gas reserves and
in projecting future rates of production and timing of development
expenditures, including many factors beyond the control of the Company.
Reserve engineering is a subjective process of estimating underground
accumulations of oil and natural gas that cannot be measured in an exact way,
and the accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation and judgment.
As a result, estimates made by different engineers often vary from one
another. In addition, results of drilling, testing and production subsequent
to the date of an estimate may justify revisions of such estimate and such
revisions, if significant, would change the schedule of any further production
and development drilling. Accordingly, reserve estimates are generally
different from the quantities of oil and natural gas that are ultimately
recovered. Additional important factors that could cause actual results to
differ materially from the Company's expectations are disclosed under "Risk
Factors" and elsewhere in this Prospectus. All subsequent written and oral
forward-looking statements attributable to the Company or persons acting on
its behalf are expressly qualified in their entirety by such factors. The
forward-looking statements contained in this Prospectus are not within the
Safe Harbor for forward-looking statements contained in Section 27A of the
Securities Act and Section 21E of the Exchange Act since this is an initial
public offering.

                                 RISK FACTORS
 
  The following factors, together with the other information contained in this
Prospectus, should be considered carefully before purchasing the Notes offered
hereby.
 
SUBSTANTIAL LEVERAGE
 
  As of September 30, 1997, as adjusted for the Offering and the application
of the proceeds therefrom and the Transactions, the total indebtedness of SRH
and Southwest, including current portion, would have been $199.9 million. See
"Capitalization." In addition, the Indenture allows the Issuer, SRH and its
other Restricted Subsidiaries to incur a maximum of $51 million in additional
Indebtedness under certain circumstances. See "Description of Notes--
Covenants."
 
  The Company's level of indebtedness has several important effects on its
operations, including: (i) the covenants may limit its ability to borrow
additional funds or to dispose of assets and may affect the Company's
flexibility in planning for, and reacting to, changes in business conditions,
(ii) the Company's ability to obtain additional financing in the future for
working capital, capital expenditures, acquisitions, general corporate
purposes or other purposes may be impaired, and (iii) a substantial portion of
the Company's cash flow may be dedicated to the payment of interest. Moreover,
future acquisition or development activities may require the Company to alter
its capitalization significantly. These changes in capitalization may
significantly alter the leverage of the Company. The Company's ability to meet
its debt service obligations and to reduce its total indebtedness will be
dependent upon the Company's future performance, which will be subject to
general economic conditions and to financial, business and other factors
affecting the operations of the Company, many of which are beyond its control.
There can be no assurance that the Company's future performance will not be
adversely affected by such economic conditions and financial, business and
other factors. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
  Certain holders, who collectively own approximately 12% of SRH's common
stock, have an option to cause SRH to redeem such holders' common stock at any
time beginning December 31, 2001, five years from the date of issuance of such
common stock, subject to the terms of a subscription agreement under which SRH
sold the common stock (the "Subscription Agreement") and subject to any
restrictions imposed by law. The Subscription Agreement provides that this
redemption right terminates on the effective date of any registration
statement under the Securities Act filed with the Commission relative to the
offer and sale of any amount of SRH's common stock to the public. SRH is
unable to predict the amount of money it would be required to pay if the
redemption right is exercised. The Indenture may also restrict SRH's ability
to make such payments. In addition, SRH can give no assurance that it will be
able to cause a registration statement to become effective under the
Securities Act in order to terminate the redemption option. If SRH is unable
to make the payments required upon exercise of the redemption right, it would
be subject to suit for breach of contract.
 
PAYMENT UPON A CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, each holder of the Notes may
require the Issuer to purchase all or a portion of such holder's Notes at 101%
of the principal amount of the Notes, together with accrued and unpaid
interest, if any, to the date of purchase. If a Change of Control were to
occur, the Issuer may not have the financial resources to repay all of the
Notes and the other indebtedness that might become payable upon the occurrence
of such Change of Control. See "Description of Notes--Repurchase of Notes at
the Option of the Holder Upon a Change of Control."
 
ADEQUACY OF COLLATERAL; RISKS OF FORECLOSURE
 
  SRH has pledged to the Trustee (under the Indenture), for the ratable
benefit of the holders of the Notes, all of the Sierra common stock and Red
Oak common stock directly owned by SRH as security for the Parent Guarantee
(collectively, the "Collateral").
 
  In the event of a default under the Indenture, there can be no assurance
that the Trustee would be able to foreclose on or dispose of any of the
Collateral without substantial delays and other risks or that the proceeds
obtained therefrom would be sufficient to pay all amounts owing to holders of
the Notes. SRH would be required
 
                                      19
<PAGE>
 
to file a shelf registration statement and any of SRH's other subsidiaries
whose stock is pledged to the Trustee would be required to grant registration
rights with respect to such stock, in each case to allow the Trustee to be
able to sell the pledged shares of their common stock publicly. Circumstances
beyond the control of the Company, however, may delay the availability of a
current prospectus. There is currently no public market for the shares of SRH
common stock and there can be no assurance that there will be any public
market for the common stock of any subsidiary of SRH.
 
  In addition, if the Issuer becomes a debtor in a case under the United
States Bankruptcy Code (the "Bankruptcy Code"), the automatic stay imposed by
the Bankruptcy Code would prevent the Trustee from selling or otherwise
disposing of the Collateral without bankruptcy court authorization. In that
case, the foreclosure might be delayed indefinitely. Moreover, the bankruptcy
of any entity related to the Issuer might result in a similar delay if the
Issuer were "substantively consolidated" with the related entity.
 
POSSIBLE LIMITATIONS ON ENFORCEABILITY OF SUBSIDIARY GUARANTEES
 
  The Issuer's obligations under the Notes may under certain circumstances be
guaranteed on a senior unsecured basis by the Subsidiary Guarantors. Various
fraudulent conveyance laws have been enacted for the protection of creditors
and may be utilized by a court of competent jurisdiction to subordinate or
void any Subsidiary Guarantee issued by a Subsidiary Guarantor. It is also
possible that under certain circumstances a court could hold that the direct
obligations of a Subsidiary Guarantor could be superior to the obligations
under its Subsidiary Guarantee.
 
  To the extent that a court were to find that at the time a Subsidiary
Guarantor entered into a Subsidiary Guarantee either (1) the Subsidiary
Guarantee was incurred by the Subsidiary Guarantor with the intent to hinder,
delay or defraud any present or future creditor or that the Subsidiary
Guarantor contemplated insolvency with a design to favor one or more creditors
to the exclusion in whole or in part of others or (2) the Subsidiary Guarantor
did not receive fair consideration or reasonably equivalent value for issuing
the Subsidiary Guarantee and, at the time it issued the Subsidiary Guarantee,
the Subsidiary Guarantor (i) was insolvent or rendered insolvent by reason of
the issuance of the Subsidiary Guarantee, (ii) was engaged or about to engage
in a business or transaction for which the remaining assets of the Subsidiary
Guarantor constituted unreasonably small capital or (iii) intended to incur,
or believed that it would incur, debts beyond its ability to pay such debts as
they matured, the court could void or subordinate the Subsidiary Guarantee in
favor of the Subsidiary Guarantor's other creditors. Among other things, a
legal challenge of a Subsidiary Guarantee issued by a Subsidiary Guarantor on
fraudulent conveyance grounds may focus on the benefits, if any, realized by
the Subsidiary Guarantor as a result of the issuance by the Issuer of the
Notes. To the extent that proceeds from the Offering are used to refinance the
indebtedness of the Company, a court might find that the Subsidiary Guarantors
did not benefit from incurrence of the indebtedness represented by the Notes.
 
  The measure of insolvency for purposes of determining whether a transfer is
voidable as a fraudulent transfer varies depending upon the law of the
jurisdiction that is being applied. Generally, however, a debtor would be
considered insolvent if the sum of all its debts, including contingent
liabilities, was greater than the value of all its assets at a fair valuation
or if the present fair saleable value of the debtor's assets was less than the
amount required to repay its probable liability on its debts, including
contingent liabilities, as they become absolute and mature.
 
  To the extent that a Subsidiary Guarantee is voided as a fraudulent
conveyance or found unenforceable for any other reason, holders of the Notes
would cease to have any claim in respect of the applicable Subsidiary
Guarantor. In such event, the claims of the holders of the Notes against such
Subsidiary Guarantor would be subject to the prior payment of all liabilities
and preferred stock claims of such Subsidiary Guarantor. There can be no
assurance that, after providing for all prior claims and preferred stock
interests, if any, there would be sufficient assets to satisfy the claims of
the holders of the Notes relating to any voided portion of such Subsidiary
Guarantee.

LACK OF PUBLIC MARKET; RESTRICTION ON TRANSFERABILITY
 
  The Notes are a new securities issue for which there is currently no active
trading market. If the Notes are traded after their initial issuance, they may
trade at a discount from their initial offering price, depending upon
prevailing interest rates, the market for similar securities and other
factors, including general economic conditions and the financial condition of
the Company. The Issuer does not currently intend to apply for a listing or
quotation of the Notes or the Exchange Notes, on any securities exchange or
stock market. The Initial Purchasers have informed the Issuer that they
currently intend to make a market in the Notes and the Exchange Notes.
However, the Initial Purchasers are not obligated to do so, and any such
market making may be discontinued at any time without notice. No assurance can
be given as to the liquidity of the trading market for the Notes and, if
issued, the Exchange Notes. Accordingly, there can be no assurance as to the
development or liquidity of any market for the Notes.
 
  The Exchange Notes generally will be permitted to be resold or otherwise
transferred (subject to the restrictions described under "Exchange and
Registration Rights Agreement" and "Notice to Investors") by each holder of
the Exchange Notes without the requirement of further registration. The
Exchange Offer will not be conditioned upon any minimum or maximum aggregate
principal amount of Notes being tendered for exchange. No assurance can be
given as to the liquidity of the trading market for the Exchange Notes, or, in
the case of non-tendering holders of the Old Notes, the trading market for the
Old Notes following the Exchange Offer. Holders of Old Notes who do not accept
the Exchange Offer will continue to hold restricted Notes subject to certain
transfer restrictions. Any benefits they had under the Registration Rights
Agreement herein described will be terminated.
 
  The liquidity of, and trading market for, the Notes or the Exchange Notes
also may be adversely affected by general declines in the market for similar
securities. Such a decline may adversely affect such liquidity and trading
markets independent of the financial performance of the Company.
 
VOTING CONTROL
 
  As of September 30, 1997, H. H. Wommack, III, Chairman of the Board,
President and Chief Executive Officer of SRH and Southwest, owned 72.9% of the
outstanding voting shares of common stock of SRH, which owns 100% of the
common stock of Southwest. See "Principal Stockholders and Ownership of
Management." Therefore, Mr. Wommack has the ability to elect all of the
directors of SRH and Southwest and, directly and indirectly, influence all
decisions made by SRH and Southwest.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company depends to a large extent on the services of H. H. Wommack, III
and certain other senior management personnel. See "Management." The loss of
the services of Mr. Wommack and other senior management personnel could have a
material adverse effect on the Company's operations. The Company does not
currently have an employment contract with any senior management or key
personnel. The Company believes that its success is also dependent upon its
ability to continue to employ and retain skilled technical personnel. The
inability of the Company to employ or retain skilled technical personnel could
have a material adverse effect on the Company's operations. Although the
Company maintains key man life insurance on the life of Mr. Wommack in the
amount of $7.5 million, the existence of such insurance does not mean that the
death or disability of Mr. Wommack would not have a materially adverse effect
upon the Company.
 
VOLATILITY OF OIL AND NATURAL GAS PRICES
 
  Revenues generated from Southwest's operations are highly dependent upon the
price of, and demand for, oil and natural gas. Historically, the markets for
oil and natural gas have been volatile and are likely to continue to be
volatile in the future. Prices for oil and natural gas are subject to wide
fluctuations in response to relatively minor changes in the supply of and
demand for oil and natural gas, market uncertainty and a variety of additional
factors that are beyond the control of Southwest. These factors include the
level of consumer product demand, weather conditions, domestic and foreign
governmental regulations, the price and availability of alternative fuels,
political conditions in the Middle East, the foreign supply of oil and natural
gas, the price of foreign imports and
 
                                      21

overall economic conditions. It is impossible to predict future oil and
natural gas price movements with any certainty. Declines in oil and natural
gas prices may materially adversely affect Southwest's financial condition,
liquidity and results of operations. Lower oil and natural gas prices also may
reduce the amount of Southwest's oil and natural gas that can be produced
economically. In order to reduce its exposure to price risks in the sale of
its oil and natural gas, Southwest may enter into hedging arrangements from
time to time; however, Southwest's hedging arrangements are likely to apply to
only a portion of its production and provide only limited price protection
against fluctuations in the oil and natural gas markets. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
General" and "Business."
 
  Southwest uses the full cost method of accounting for its investment in oil
and natural gas properties. Under the full cost method of accounting, all
costs of acquisition, exploration and development of oil and natural gas
reserves are capitalized into a "full cost pool" as incurred, and properties
in the pool are depleted and charged to operations using the future gross
revenues method based on the ratio of current gross revenues to total proved
future gross revenues, computed based on current prices. Significant downward
revisions of quantity estimates or declines in oil and natural gas prices that
are not offset by other factors could result in a write down for impairment of
oil and natural gas properties. Once incurred, a write down of oil and natural
gas properties is not reversible at a later date even if oil or natural gas
prices increase.
 
RISKS OF ACQUISITION STRATEGY
 
  The Company's growth strategy includes the acquisition of oil and gas
properties, well servicing businesses and commercial real estate properties.
There can be no assurance, however, that the Company will be able to continue
to identify attractive acquisition opportunities, obtain financing for
acquisitions on satisfactory terms or successfully acquire identified targets.
In addition, no assurance can be given that the Company will be successful in
integrating acquired businesses into its existing operations, and such
integration may result in unforeseen operational difficulties or require a
disproportionate amount of management's attention. Future acquisitions may be
financed through the incurrence of additional indebtedness to the extent
permitted under the Indenture or through the issuance of capital stock.
Furthermore, there can be no assurance that competition for acquisition
opportunities in these industries will not escalate, thereby increasing the
cost to the Company of making further acquisitions or causing the Company to
refrain from making additional acquisitions.
 
REPLACEMENT OF RESERVES
 
  In general, the volume of production from oil and natural gas properties
declines as reserves are depleted. Except to the extent Southwest acquires
properties containing proved reserves or conducts successful development and
exploration activities, or both, the proved reserves of Southwest will decline
as reserves are produced. Southwest's future oil and natural gas production
is, therefore, highly dependent upon its level of success in finding or
acquiring additional reserves. The business of exploring for, developing or
acquiring reserves is capital intensive. To the extent cash flow from
operations is reduced and external sources of capital become limited or
unavailable, Southwest's ability to make the necessary capital investment to
maintain or expand its asset base of oil and natural gas reserves would be
impaired. In addition, there can be no assurance that Southwest's future
development, acquisition and exploration activities will result in additional
proved reserves or that Southwest will be able to drill productive wells at
acceptable costs.
 
UNCERTAINTY OF RESERVE INFORMATION AND FUTURE NET REVENUE ESTIMATES
 
  There are numerous uncertainties inherent in estimating oil and natural gas
reserves and their estimated values, including many factors beyond the control
of Southwest. The reserve data set forth in this Prospectus represent only
estimates. Reservoir engineering is a subjective process of estimating
underground accumulations of oil and natural gas that cannot be measured in an
exact manner. Estimates of economically recoverable oil and natural gas
reserves and of future net cash flows necessarily depend upon a number of
variable factors and assumptions, such as historical production from the area
compared with production from other producing areas, the assumed effects of
regulations by governmental agencies and assumptions concerning future oil and
natural
 
                                      22
<PAGE>
 
gas prices, future operating costs, severance and excise taxes, development
costs and workover and remedial costs, all of which may in fact vary
considerably from actual results. For these reasons, estimates of the
economically recoverable quantities of oil and natural gas attributable to any
particular group of properties, classifications of such reserves based on risk
recovery and estimates of the future net cash flows expected therefrom
prepared by different engineers or by the same engineers at different times
may vary substantially and such reserve estimates may be subject to downward
or upward adjustment based upon such factors. Actual production, revenues and
expenditures with respect to Southwest's reserves will likely vary from
estimates, and such variances may be material. See "Business--Oil and Gas
Reserves."
 
  The present values of estimated future net cash flows referred to in this
Prospectus should not be construed as the current market value of the
estimated oil and natural gas reserves attributable to Southwest's properties.
In accordance with applicable requirements of the Commission, the estimated
discounted future net cash flows from proved reserves are generally based on
prices and costs as of the date of the estimate, whereas actual future prices
and costs may be materially higher or lower. Actual future net cash flows also
will be affected by factors such as the amount and timing of actual
production, supply and demand for oil and natural gas, curtailments or
increases in consumption by gas purchasers and changes in governmental
regulations or taxation. The timing of actual future net cash flows from
proved reserves, and their actual present value, will be affected by the
timing of both the production and the incurrence of expenses in connection
with development and production of oil and natural gas properties. In
addition, the calculation of the present value of the future net revenues
using a 10% discount, as required by the Commission, is not necessarily the
most appropriate discount factor based on interest rates in effect from time
to time and risks associated with Southwest's reserves or the oil and natural
gas industry in general.
 
SUBSTANTIAL CAPITAL REQUIREMENTS
 
  Southwest makes, and will continue to make, substantial capital expenditures
for the exploration, development and acquisition of oil and natural gas
reserves. Southwest made capital expenditures of $32.1 million during 1995 and
$16.7 million during 1996. For the nine months ended September 30, 1997,
Southwest has spent approximately $27 million in the aggregate for oil and gas
acquisition, development and exploration activities and has budgeted
additional capital spending of approximately $45 million for the remainder of
1997 and 1998, principally to complete over 190 planned development drilling
and recompletion projects. The $45 million budgeted for capital spending is in
addition to the $72.3 million purchase price of the Oil and Gas Properties
Acquisition completed October 14, 1997. Although management believes that
Southwest will have sufficient cash provided by operating activities, bank
lines and the proceeds from the Offering to fund planned capital expenditures
in 1997 and 1998, if revenues decrease as a result of lower oil and natural
gas prices or operating difficulties, Southwest may be limited in its ability
to expend the capital necessary to undertake or complete its drilling program
in future years. There can be no assurance that additional debt or equity
financing or cash generated by operations will be available to meet these
requirements. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources."
 
DRILLING RISKS
 
  Drilling involves numerous risks, including the risk that no commercially
productive oil or natural gas reservoirs will be encountered. The cost of
drilling, completing and operating wells is often uncertain, and drilling
operations may be curtailed, delayed or canceled as a result of a variety of
factors, including unexpected drilling conditions, pressure or irregularities
in formations, equipment failures or accidents, adverse weather conditions,
title problems and shortages or delays in the delivery of equipment.
Southwest's future drilling activities may not be successful and, if
unsuccessful, such failure will have an adverse effect on Southwest's future
results of operations and financial condition.
 
MARKETABILITY OF PRODUCTION
 
  The marketability of Southwest's oil and natural gas production depends upon
the availability and capacity of gas gathering systems, pipelines and
processing facilities, and the unavailability or lack of capacity thereof
could result in the shut-in of producing wells or the delay or discontinuance
of development plans for properties.
 
                                      23
<PAGE>
 
In addition, federal and state regulation of oil and natural gas production
and transportation, general economic conditions and changes in supply and
demand could adversely affect Southwest's ability to produce and market its
oil and natural gas on a profitable basis.
 
OPERATING RISKS OF OIL AND NATURAL GAS OPERATIONS
 
  The oil and natural gas business involves a variety of operating risks,
including the risk of fire, explosions, blowouts, pipe failure, casing
collapse, abnormally pressured formations and hazards such as oil spills,
natural gas leaks, ruptures or discharges of toxic gases. The occurrence of
any of these operating risks could result in substantial losses to Southwest
due to injury or loss of life, severe damage to or destruction of property and
equipment, pollution or other environmental damage, including damage to
natural resources, clean-up responsibilities, penalties and suspension of
operations. In accordance with customary industry practice, Southwest
maintains insurance against some, but not all, of the risks described above.
There can be no assurance that any insurance obtained by Southwest will be
adequate to cover any losses or liabilities. Southwest cannot predict the
continued availability of insurance or the availability of insurance at
premium levels that justify its purchase.
 
COMPLIANCE WITH GOVERNMENTAL REGULATIONS
 
  The Company's oil and natural gas and well service operations are subject to
various federal, state and local governmental laws and regulations that may be
changed from time to time in response to economic or political conditions.
Matters subject to regulation include discharge permits for drilling
operations, drilling and abandonment bonds or other financial responsibility
requirements, reports concerning operations, the spacing of wells, utilization
and pooling of properties and taxation. From time to time, regulatory agencies
have imposed price controls and limitations on production by restricting the
rate of flow of oil and natural gas wells below actual production capacity to
conserve supplies of oil and natural gas. In addition, the production,
handling, storage, transportation and disposal of oil and natural gas, by-
products thereof and other substances and materials produced or used in
connection with oil and natural gas operations are subject to regulation under
federal, state and local laws and regulations primarily relating to protection
of human health and the environment. These laws and regulations may impose
increasingly strict requirements for water and air pollution control and solid
waste management and can result in the imposition of civil and even criminal
penalties.
 
  The Company's commercial real estate properties are subject to various
federal, state and local regulatory requirements, such as laws with respect to
access by disabled persons and state and local fire and life safety
requirements. Failure to comply with these requirements could result in the
imposition of fines by governmental authorities or awards of damages to
private litigants. The Company believes that the properties are currently in
compliance in all material respects with all such regulatory requirements.
However, there can be no assurance that these requirements will not be changed
or that new requirements will not be imposed which would require significant
unanticipated expenditures by the Company's real estate business and could
have an adverse effect on expected distributions by the Company's real estate
business.
 
SUBSTANTIAL COMPETITION
 
  The Company experiences intense competition in its markets. Such markets are
highly competitive and no one competitor is dominant. Southwest competes with
major and independent oil and natural gas companies for the acquisition of
desirable oil and natural gas properties, as well as for the equipment and
labor required to develop and operate such properties. Southwest also competes
with major and independent oil and natural gas companies in the marketing and
sale of oil and natural gas to marketers and end-users. Sierra competes on the
basis of the quality of its equipment and service, its safety record and
pricing. Several competitors have access to greater financial and other
resources than those of Sierra, which could allow those companies to price
their services more aggressively than Sierra. Red Oak competes with other
companies for the acquisition of desirable real estate properties principally
on the basis of price. Although the Company believes that it has certain
advantages over these competitors, some of these competitors have greater
financial and other resources than the Company. See "Business--Competition."
 
                                      24
<PAGE>
 
ENVIRONMENTAL RISKS
 
  The Company is subject to a variety of federal, state and local governmental
regulations related to the storage, use, discharge and disposal of toxic,
volatile or otherwise hazardous materials. The Company does not currently
anticipate any material adverse effect on its business, financial condition or
results of operations as a result of the Company's required compliance with
U.S. federal, state, provincial, local or foreign environmental laws or
regulations or remediation costs. However, some risk of environmental
liability and other costs is inherent in the nature of the Company's business.
Moreover, the Company anticipates that such laws and regulations will become
increasingly stringent in the future, which could lead to material costs for
environmental compliance and remediation by the Company. See "Business--
Regulation."
 
  Any failure by the Company to obtain required permits for, control the use
of, or adequately restrict the discharge of, hazardous substances under
present or future regulations could subject the Company to substantial
liability or could cause its operations to be suspended. Such liability or
suspension of operations could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
SIERRA OPERATIONS--DEPENDENCE ON OIL AND GAS INDUSTRY; INDUSTRY CONDITIONS
 
  Sierra's business is substantially dependent upon conditions in the oil and
gas industry and, specifically, the expenditures of oil and gas companies. The
demand for well servicing activities is directly influenced by oil and gas
prices, expectations about future prices, the cost of producing and delivering
oil and gas, government regulation, including environmental regulations, local
and international political and economic conditions, and governmental policies
regarding exploration and development of oil and gas reserves. The demand for
well servicing and related services in the United States was severely
depressed for most of the last decade due in large part to prolonged weakness
and uncertainty in oil and gas prices. As a consequence, diminished demand
during that period led to lower rates and reduced use of available equipment.
Demand for well services has improved over the last two years, and prices for
such services have stabilized or increased during that period. Nonetheless,
there can be no assurance that periods of diminished demand in the oil field
service industry will not occur.
 
RED OAK OPERATIONS--ECONOMIC PERFORMANCE AND VALUE OF REAL ESTATE DEPENDENT ON
MANY FACTORS
 
  Real estate property investments are subject to varying degrees of risk. The
economic performance and values of real estate can be affected by many
factors, including changes in the national, regional and local economic
climates, local conditions such as an oversupply of space or a reduction in
demand for real estate in the area, the attractiveness of the properties to
tenants, competition from other available space, the ability of the owner to
provide adequate maintenance and insurance and increased operating costs. In
recent years, there has been a proliferation of new retailers and a growing
consumer preference for value-oriented shopping alternatives that have, among
other factors, heightened competitive pressures. In certain areas of the
country, there may also be an oversupply of retail space. As a consequence,
many companies in all sectors of the retailing industry have encountered
significant financial difficulties. A substantial portion of Red Oak's income
is derived from rental revenues from retailers in neighborhood and community
shopping centers. Red Oak's income would be adversely affected if a
significant number of Red Oak's tenants were unable to meet their obligations
to Red Oak or if Red Oak were unable to lease a significant amount of space in
its properties on economically favorable lease terms. Accordingly, no
assurance can be given that Red Oak's financial results will not be adversely
affected by these developments in the retail industry.

                                  THE COMPANY
 
  SRH, a Delaware corporation, was formed in 1997 to serve as a holding
company for Southwest, Sierra and Red Oak. The principal operating subsidiary
of SRH is Southwest, a Delaware corporation that was formed in 1983 to acquire
and develop oil and gas properties. Southwest initially financed the
acquisition of oil and gas reserves and its exploration and development
efforts through public and private limited partnership offerings. Southwest
raised approximately $115 million in 31 public and private limited partnership
offerings from 1983 to 1994. Southwest is a general partner of these limited
partnerships, owns interests in these partnerships and receives management
fees and operating cost reimbursements from such partnerships. Since
inception, Southwest, on behalf of itself and the investment partnerships, has
acquired over $320 million of oil and gas properties. As of June 30, 1997,
Southwest had total estimated net proved reserves of 32.5 MMBbls of oil and
75.3 Bcf of natural gas, aggregating 45.0 MMBoe, with a PV-10 Value of
approximately $214.5 million. Southwest's primary operations are in the
Permian Basin of West Texas and southeastern New Mexico. Southwest is the
Issuer of the Notes and a Restricted Subsidiary of SRH, the guarantor of the
Notes.
 
  Sierra, a Delaware corporation, was formed in 1992 to provide certain well
services for Southwest and other oil and gas companies. Sierra expanded its
focus to provide a broader range of services, including workover rig services,
liquids handling and other services. Since January 1996, Sierra has pursued a
consolidation strategy, acquiring 15 well servicing companies in New Mexico
and Texas. SRH directly owns approximately 26% of the common stock of Sierra
and indirectly owns an additional 10% interest through Southwest, which is the
general partner and 15% interest holder in two partnerships that own
approximately 64% of the common stock of Sierra. This direct and indirect
ownership by SRH and the position of Southwest as general partner of the
partnerships, provides SRH with effective voting control of Sierra. Sierra, an
affiliate of SRH, is not classified as a Subsidiary of SRH for purposes of the
Indenture.
 
  Red Oak, a Delaware corporation, was formed in 1992 to own and manage
commercial real estate properties, including shopping centers and office
buildings, in secondary real estate markets in the southwestern United States.
Through October 31, 1997, Red Oak has acquired 17 commercial real estate
properties for $82.8 million. SRH owns approximately 82% of the common stock
of Red Oak on a fully-diluted basis. Red Oak is an Unrestricted Subsidiary.

  Southwest has three subsidiaries, Midland Southwest Software, Inc.
("Southwest Software"), Threading Products International, LLC ("TPI"), and
Blue Heel Company ("Blue Heel"), in which Southwest owns approximately 99%,
97%, and 100%, respectively, of the common stock or membership interests.
Southwest

Software creates and markets computer software to the oil and gas industry.
TPI produces inserts used to cut threads by manufacturers of threaded
products. Blue Heel holds a nominal interest in certain oil and gas properties
owned by Southwest. Southwest also owns 40% of the membership interests in SWV
Aviation, LLC, which owns an aircraft used by the Company and others.
Software, TPI and Blue Heel will be Restricted Subsidiaries under the terms of
the Indenture, but SWV Aviation, LLC will not be a Subsidiary thereunder.
Sierra currently has no subsidiaries, but expects to form or acquire
subsidiaries as a result of future acquisition activities, none of which would
be Subsidiaries for purposes of the Indenture. Red Oak has two wholly-owned
subsidiaries, MRO Properties, Inc. ("MROP") and MRO Management, Inc. ("MRO
Management"), both of which will be Unrestricted Subsidiaries. MROP holds
titles to certain real estate properties and is the borrower under a credit
agreement related to such properties. This credit agreement is non-recourse to
Red Oak. MRO Management performs real estate management services for MROP and
Red Oak.     
 
  Both Sierra and Red Oak are operated separately from Southwest; however,
Southwest provides both with significant administrative and accounting
support. Under the terms of separate service agreements dated September 1,
1997, Southwest has agreed to provide to Sierra and Red Oak administrative
services including accounting, bookkeeping, tax preparation and banking and
disbursement services. Both agreements have an initial term of five years and
renew from year to year if not terminated. Under each agreement, Southwest
receives a fixed fee of $12,000 per month. These fees may be adjusted at any
time by agreement of the parties. The service agreements may be terminated
upon 30 days' notice by either party to the agreements.
 
  SRH has also entered into a tax sharing agreement effective September 1,
1997 with Southwest and Red Oak. This agreement provides, in general, that the
consolidated federal income tax liability of the members of the consolidated
group will be apportioned among the members in accordance with the method set
forth in Section 1.152-1(a)(2) of the Internal Revenue Code of 1986, as
amended and Sections 1.1502-33(d)(2)(i) of the Regulations promulgated
thereunder. In order to compensate members of the consolidated group for the
use of any net operating losses or tax credits and arriving at the
consolidated federal income tax liability for the group, group members have
agreed to determine and allocate the tax liability among themselves as
provided in the tax regulations.

                               PRIVATE PLACEMENT
 
  On October 14, 1997, Southwest completed a $200 million private placement
sale of the Old Notes to the Initial Purchasers. Thereupon the Old Notes were
offered and sold by the Initial Purchasers only to qualified institutional
buyers. The net proceeds from the Private Placement were approximately $190
million. The Issuer used the net proceeds primarily to (i) fund the Oil and
Gas Properties Acquisition (net of deposits paid), (ii) repay substantially
all indebtedness outstanding under Southwest's bank credit facility and its
reserve-based loan facilities, (iii) fund a $10 million equity investment by
SRH in Red Oak through a dividend in that amount from the Issuer to SRH, (iv)
make a general partner capital contribution to Partners III of approximately
$1.7 million, which funds were immediately invested in Sierra common stock,
and (v) provide additional working capital for general corporate purposes,
including future acquisitions and development of producing oil and gas
properties. The following table illustrates the sources and uses of the gross
proceeds of the Offering:

(3) Earnings were insufficient to cover fixed charges by $3,149,000, $33,000
    and $4,465,000 for the historical periods ended December 31, 1995,
    September 30, 1996 and September 30, 1997, respectively, and $9,908,000
    and $11,680,000 for the pro forma periods ended December 31, 1996 and
    September 30, 1997, respectively. For purposes of computing the ratio of
    earnings to fixed charges, earnings are computed as income (loss) before
    extraordinary item plus minority interest in subsidiaries and income
    taxes, plus fixed charges. Fixed charges consist of interest expense and
    an estimated portion of rentals representing interest costs.
(4) Adjusted EBITDA (as used herein) is calculated based on the Indenture,
    which requires EBITDA to be calculated by adding the net income (loss) of
    SRH (as defined on page 5 of this Prospectus) and its Restricted
    Subsidiaries, excluding the net income (loss) of any Unrestricted
    Subsidiary, to minority interest in subsidiaries, income tax benefit
    (provision) and depreciation, depletion and amortization of SRH and
    interest expense of SRH and its Restricted Subsidiaries. Specifically, net
    income (loss), income tax benefit (expense), interest expense and
    depreciation, depletion and amortization of Red Oak is excluded from the
    calculation of Adjusted EBITDA, as Red Oak is an Unrestricted Subsidiary.
    EBITDA is used because the Company believes it is commonly used by debt
    holders and financial statement users as a measurement to determine the
    ability of an entity to meet its interest obligations. EBITDA is not a
    measurement presented in accordance with generally accepted accounting
    principles ("GAAP") and is not intended to be used in lieu of GAAP
    presentation of results of operations and cash provided by operating
    activities.
(5) Adjusted EBITDA to Interest (as used herein) is the ratio of Adjusted
    EBITDA to interest on the Notes plus interest on any other debt of SRH and
    any Restricted Subsidiary.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
  SRH is a holding company that conducts its operations through three
principal businesses. The Company's oil and gas operations are conducted
through Southwest, primarily in the Permian Basin of West Texas and
southeastern New Mexico. Well servicing operations, consisting of workover rig
services, liquids handling and other services, are conducted through Sierra in
Texas and New Mexico. Real estate operations are conducted through Red Oak and
are focused in Texas, Oklahoma and Arizona.
 
  The Company has grown substantially over the last several years primarily
through acquisitions in each of its businesses. As a result of these
acquisitions, operating results may not be comparable from period to period.
The Company's acquisition expenditures for the period from 1994 to September
30, 1997, by business, are listed below:

  On October 14, 1997, the Company purchased additional oil and gas properties
in the Permian Basin from a major oil company for $72.3 million.
 
  As previously indicated, a substantial portion of the Company's revenue
growth for the past several years has been the result of acquisitions. The
Company will continue to place emphasis on profitable acquisition
opportunities as long as such opportunities exist. However, the Company
understands the cyclical nature of the oil and gas industry. Therefore, the
Company is also actively seeking to develop its inventory of existing proved
developed non-producing and proved undeveloped reserves. The Company's staff
and operations are structured to be able to shift emphasis between
acquisitions and reserve development depending on market conditions. Because
the Company actively pursues both avenues of development, no overly disruptive
operational restructuring is required when the Company decides to shift its
focus.
 
  Historically, the Company has placed more emphasis on acquisitions than
reserve development. Management believes, however, that if operations were to
shift toward reserve development, a stable revenue stream would be generated
which would increase as development projects were completed. A significant
portion of the Company's reserves are proved undeveloped and are therefore
available for development. The Company budgeted approximately $102.7 million
in 1997 and $44.9 million in 1998 for oil and gas acquisitions, development
and exploration. In 1997, $19.9 million of the $102.7 million was budgeted for
development and exploration. Of the $44.9 million budgeted for 1998, $24.3
million is allocated to development and exploration. If management determines
that there are fewer acquisition opportunities than expected, it will seek to
allocate additional funds to development and exploration activities.
 
  Southwest's revenue, profitability and cash flow are substantially dependent
upon prevailing prices for crude oil and natural gas and the volumes of crude
oil and natural gas it produces. In addition, Southwest's proved reserves and
oil and gas production will decline as crude oil and natural gas are produced
unless Southwest is successful in acquiring producing properties or conducts
successful exploration and development activities.
 
  Southwest uses the full cost method of accounting for its investment in oil
and gas properties. Under the full cost method of accounting, all costs of
acquisition, exploration and development of oil and gas reserves are
capitalized into a "full cost pool" as incurred, and properties in the pool
are depleted and charged to operations
 
                                      34
<PAGE>
 
using the future gross revenues method based on the ratio of current gross
revenues to total proved future gross revenues, computed based on current
prices. Significant downward revisions of quantity estimates or declines in
oil and gas prices that are not offset by other factors could result in a
write down for impairment of oil and gas properties. Once incurred, a
writedown of oil and gas properties is not reversible at a later date, even if
oil or natural gas prices increase.
 
  The Sierra Equity Sale resulted in a reduction in the direct ownership of
Sierra by SRH to approximately 26%. Beginning July 1, 1997, SRH began
accounting for its ownership of Sierra as an investment in an unconsolidated
subsidiary, consistent with the equity method of accounting under GAAP.

</TABLE>
 
  Oil and gas revenues increased $1.4 million, or 6%, for the nine months
ended September 30, 1997 compared to the same period in 1996, due primarily to
increases in oil production. Oil and gas production increased 10% and 4%,
respectively, due principally to several acquisitions. Changes in production
contributed $1.8 million to increased oil and gas revenues. The average price
per barrel of oil was $19.39, a decrease of 2%, and the average price of
natural gas was $2.01 per Mcf, a decrease of 2%, for the nine months ended
September 30, 1997 compared to the prior period. These lower oil and gas
prices contributed to a decrease of $436,000 to revenues.
 
  Well servicing revenues increased $1.6 million, or 26%, attributable
primarily to acquisitions completed in the last half of 1996 and first half of
1997, as well as an increase in rates for well servicing rigs resulting from
increased demand for workover and completion services, partially offset by the
effects of deconsolidating Sierra at July 1, 1997. The Sierra Equity Sale
resulted in a reduction in the direct ownership of Sierra by SRH to
approximately 26%. Beginning July 1, 1997, SRH began accounting for its
ownership of Sierra as an investment in an unconsolidated subsidiary,
consistent with the equity method of accounting under GAAP. Real estate
operations revenues increased $1.9 million, or 63%, for the nine months ended
September 30, 1997, due primarily to acquisitions completed in the last half
of 1996 and first three quarters of 1997. Other operating revenues increased
524,000 or 124% due primarily to TPI, a small manufacturing subsidiary of
Southwest, which has increased its market share since commencing operations in
1994.
 
  Operating Expenses. Operating expenses, before general and administrative
expense and depreciation, depletion and amortization, increased $3.6 million,
or 21%, for the nine months ended September 30, 1997, due primarily to growth
in the Company's businesses through acquisitions.
 
                                      35
<PAGE>
 
  Oil and gas operating expense increased $1.3 million, or 12%, for the nine
months ended September 30, 1997, due primarily to an increase in the number of
oil and gas properties owned by the Company and increased workover activity
during the period. The average operating expense was $8.10 per Boe in the nine
months ended September 30, 1997, an increase of 3% from $7.83 per Boe for the
same period in 1996. This increase in per unit operating costs was
attributable primarily to the acquisition of oil and gas properties which
affected 1997 results.
 
  Well servicing operating expense increased $1.1 million, or 23%, for the
nine months ended September 30, 1997, attributable primarily to increased
activity from recently acquired companies, partially offset by the effects of
deconsolidating Sierra at July 1, 1997. Real estate operating expense
increased $612,000, or 47%, for the nine months ended September 30, 1997, due
primarily to acquisitions. Both well servicing and real estate operating
expenses declined, 2% and 4%, respectively, as a percentage of revenues as the
Company experienced efficiencies resulting from integrating acquisitions in
each of these businesses. Other operating expenses increased $596,000 or 146%,
due primarily to the growth of TPI, a small manufacturing subsidiary of
Southwest, which commenced operations in 1994.
 
  General and Administrative ("G&A") Expense. G&A expense for the Company
increased $479,000, or 10%, for the nine months ended September 30, 1997, due
primarily to an increase in the Company's activities resulting from recent
acquisitions. Oil and gas G&A expense increased approximately $768,000, or
28%, for the nine months ended September 30, 1997, and was $2.31 per Boe, an
increase of 20% from the comparable prior period, due primarily to additions
to oil and gas technical and administrative staff in conjunction with planned
increases in future oil and gas development activity. Well servicing G&A
expense increased $192,000, or 17%, for the nine months ended September 30,
1997, due primarily to growth through acquisitions and increased business
insurance expense associated with those acquisitions, partially offset by the
effects of deconsolidating Sierra at July 1, 1997. Well servicing G&A expense
declined as a percentage of revenues as the Company experienced the benefits
of scale resulting from acquisitions in this business. Real estate G&A expense
decreased $31,000, or 6%, for the nine months ended September 30, 1997.
 
  Depreciation, Depletion and Amortization ("DD&A") Expense. DD&A expense for
the Company increased $1.8 million, or 30%, for the nine months ended
September 30, 1997 due to growth in each of the Company's businesses. Oil and
gas DD&A expense increased approximately $1.4 million, or 28%, and was $4.08
per Boe, an increase of 20% from the comparable prior period. The increase in
oil and gas DD&A expense on an overall basis and per Boe was due to a higher
increase in production compared to the decrease in prices which resulted in
increased revenues and a higher depletion rate. Well servicing DD&A expense
remained constant as a percentage of well servicing revenue at 10% for both
periods. Real estate DD&A expense increased as a percentage of real estate
revenues from 15% in the nine months ended September 30, 1996 to 16% in the
nine months ended September 30, 1997.
 
  Interest Expense. Interest expense for the Company increased $3.8 million,
or 53%, for the nine months ended September 30, 1997, primarily as a result of
increased borrowings incurred to fund a portion of the Company's acquisitions
and oil and gas development. Oil and gas interest expense increased
approximately $919,000, or 15%, as a result of increased borrowings for
development drilling and acquisitions made in the last quarter of 1996 and the
first three quarters of 1997. The average interest rate paid on these
borrowings also increased by approximately 1.0%. Well servicing interest
expense increased $132,000, attributable to increased debt incurred for
acquisitions, partially offset by the effects of deconsolidating Sierra at
July 1, 1997. Real estate interest expense increased $2.7 million, or 240%,
due to increased debt used to finance acquisitions and an increase of
approximately 3.0% in the average interest rate paid on these borrowings, as
compared to the prior year. This increase is primarily attributable to the
borrowing of non-recourse debt at Red Oak during the period.
 
  Other Income. Other income decreased $504,000 or 115%, due to the receipt of
an insurance settlement in 1996.
 
  Net Income. Due to the factors described above, net loss for the Company
increased $3.1 million to a loss of $3.1 million for the nine months ended
September 30, 1997.

production attributable to several acquisitions completed in late 1995, as
well as to acquisitions in 1996, resulting in an increase in revenues of $4.2
million. The average realized oil price was $20.44 per Bbl, an increase of
25%, and the average realized gas price was $2.22 per Mcf, an increase of 47%,
for 1996 as compared to 1995. These price increases resulted in increased
revenues of $7.9 million. Management fees and other oil and gas income also
increased at Southwest.
 
  Well servicing revenues increased $3.8 million, or 90%, attributable
primarily to acquisitions completed in 1996, which increased the number of
well servicing rigs owned at year end 1996 to 22 from 10 at year end 1995, as
well as to an increase in rates for well servicing rigs resulting from
increased demand for these services. Real estate revenues increased $1.3
million, or 40%, for 1996, primarily due to the acquisition of three
properties in 1996. Other operating revenues increased $270,000 or 77%, due
primarily to TPI, a small manufacturing subsidiary of Southwest, which has
increased its market shares since commencing operations in 1994.
 
  Operating Expenses. Operating expenses, before general and administrative
expense and depreciation, depletion and amortization, for the Company
increased $7.0 million, or 42%, for 1996, due primarily to growth in the
Company's businesses through acquisitions.
 
  Oil and gas operating expense increased $3.3 million, or 29%, for 1996, due
principally to the overall increase in production generated from properties
acquired during 1996 and the prior year. The average operating expense was
$7.81 per Boe in 1996, an increase of 8% from the prior year, attributable
primarily to acquisitions of properties with generally higher per unit
operating expenses and to increased production taxes resulting from higher oil
and gas prices.
 
  Well servicing operating expense increased $2.8 million, or 85%, for 1996,
attributable primarily to increases in expenses arising from acquisitions, but
partially offset by a reduction in expenses due to a shift from plugging and
abandonment to well servicing activities. Real estate operating expense
increased $473,000, or 33%, for 1996, due principally to acquisitions and
related increases in direct operating costs. Both well servicing and real
estate operating expenses declined as a percentage of revenues as the Company
experienced efficiencies resulting from acquisitions in each of these
businesses. Other operating expenses increased $326,000 or 143%, due primarily
to the growth of TPI, a small manufacturing subsidiary of Southwest, which
commenced operations in 1994.
 
  G&A Expense. G&A expense for the Company increased $1.9 million, or 39%, for
1996, due to an increase in the Company's activities resulting primarily from
acquisitions. Oil and gas G&A expense increased approximately $686,000, or
20%, for 1996, and was $2.17 per Boe in each year. This expense increased as
the result of the addition of technical and administrative personnel relating
to growth in the Company's oil and gas
 
                                      37
<PAGE>
 
business. Well servicing G&A expense increased $905,000, or 104%, for 1996
compared to the prior year, due primarily to growth through acquisitions and
the related additions of operating and administrative personnel. Real estate
G&A expense increased $232,000, or 55%, for 1996 compared to the prior year,
primarily as the result of a one time incentive compensation payment to
management. Both well servicing and real estate G&A expenses increased
slightly as a percentage of revenues.
 
  DD&A Expense. DD&A expense for the Company increased $1.7 million, or 25%,
for 1996 due primarily to acquisitions. Oil and gas DD&A expense increased
$1.4 million, or 27%, for 1996 due primarily to increases in oil and gas
production. The DD&A rate was $3.38 per Boe, an increase of 6% as compared to
1995 results. Well servicing DD&A expense increased $415,000, or 93%, and real
estate DD&A expense increased $214,000, or 48%, in 1996 compared to the prior
year, attributable primarily to the impact of acquisitions.
 
  Interest Expense. Interest expense for the Company increased $4.4 million,
or 78%, for 1996, primarily as a result of increased borrowings. Oil and gas
interest expense increased $3.7 million, or 85% for 1996, as a result of a
higher average outstanding debt balance due primarily to development
activities and acquisitions made in 1995 and 1996. Well servicing interest
expense increased $12,000 for 1996, attributable to an increase in average
debt balances. Real estate interest expense increased $632,000, or 50%, for
1996, due principally to increased debt used to finance acquisitions.
 
  Other Income/Expense. Other income increased $639,000 or 619%, due to the
receipt of an insurance settlement in 1996.
 
  Net Income. Due to the factors described above, net income for the Company
increased $2.5 million to $405,000 for 1996.
 
 Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
  Revenues. Revenues for the Company increased $10.9 million, or 55%, for
1995, reflecting increased revenues in each of the Company's businesses,
primarily from acquisitions.
 
  The following table summarizes production volumes, average sales prices and
period to period comparisons for the Company's oil and gas operations,

</TABLE>
 
  Oil and gas revenues increased $6.4 million, or 39%, from 1994 to 1995, due
principally to increased oil and gas production and oil prices. Production of
oil and gas increased 29% and 46%, respectively, due primarily to production
from acquired properties, resulting in an increase in revenues of $5.2
million. The average realized price per barrel of oil was $16.40, an increase
of 15%, and the average realized gas price was $1.51 per Mcf, a decrease of
12%, for 1995 compared to 1994. These price changes resulted in increased
revenues of $760,000 for 1995 compared to 1994. Management fees and other
income also increased at Southwest.
 
                                      38
<PAGE>
 
  Well servicing revenues increased $1.8 million, or 77%, attributable
primarily to the addition of four well servicing rigs in 1995, resulting in a
fleet of ten rigs at year end 1995 compared to six rigs at year end 1994. Real
estate revenues increased $2.6 million, for 1995, due primarily to the
acquisition of two properties in 1995. Other operating revenues increased
$27,000 or 8%, due to the addition of TPI, a small manufacturing subsidiary of
Southwest.
 
  Operating Expenses. Operating expenses, before general and administrative
expense and depreciation, depletion and amortization, for the Company
increased $6.2 million, or 60%, for 1995, due primarily to growth in the
Company's businesses through acquisitions.
 
  Oil and gas operating expense increased $3.6 million, or 46%, for 1995, due
principally to increased production from acquired properties. The average
operating expense was $7.25 per Boe in 1995, an increase of 7% from $6.80 per
Boe for the prior year, attributable primarily to acquisitions of properties
with generally higher per unit operating expenses and to increased production
taxes resulting from higher oil and gas prices.
 
  Well servicing operating expense increased $1.2 million, or 55%, for 1995,
attributable primarily to increased expense from businesses acquired. Well
servicing operating expense declined as a percentage of revenues, from 90% in
1994 to 79% in 1995 on a consolidated basis, as Sierra achieved improved
pricing for its services and efficiencies from its acquisitions. Real estate
operating expense increased $1.2 million for 1995, due to increased expense
resulting from acquisitions. Other operating expenses increased $123,000 or
117%, due to the addition of TPI, a small manufacturing subsidiary of
Southwest.
 
  G&A Expense. G&A expense for the Company increased $726,000, or 17%, for
1995, compared with 1994, due principally to an increase in the Company's
activities from acquisitions. Oil and gas G&A expense increased $123,000, or
4%, for 1995, and was $2.17 per Boe, a decrease of 24% from the prior year.
This expense increased as the result of an increase in technical and
administrative personnel attributable to growth in the oil and gas business,
but decreased on a per unit basis due primarily to increases in oil and gas
production. Well servicing G&A expense increased $437,000, or 102%, for 1995
compared to the prior year, due principally to the establishment of the East
Texas field office. Real estate G&A expense increased $6,000, or 1%, for 1995
compared to the prior year. Real estate G&A expenses declined as a percentage
of revenues as the Company experienced the benefits of scale resulting from
acquisitions.
 
  DD&A Expense. DD&A expense for the Company increased $2.3 million, or 51%,
for 1995, compared with 1994. This increase was due primarily to an increase
in oil and gas production. Oil and gas DD&A expense increased $1.6 million, or
44%, for 1995, and was $3.19 per Boe, an increase of 5%, compared to the prior
year. The increase in oil and gas DD&A expense was attributable primarily to a
doubling of the oil and gas property base resulting from acquisitions, and was
partially offset by a decreased DD&A rate. Well servicing DD&A expense
increased $294,000, or 191%, for 1995, due principally to a significant
increase in the well servicing asset base from acquisitions. Real estate DD&A
expense increased $364,000, for 1995, due primarily to the acquisition of new
properties.
 
  Interest Expense. Interest expense for the Company increased $3.7 million,
or 185%, for 1995, compared with the same period in 1994, due primarily to
increased borrowings attributable to acquisitions at Southwest and Red Oak.
Oil and gas interest expense increased $2.5 million, or 135%, for 1995. Well
servicing interest expense increased $47,000 for 1995, and real estate
interest expense increased $1.2 million for 1995.
 
  Other Income/Expense. Other income decreased $1,765,000 or 105%, due to a
gain on sale on assets in 1994.
 
  Net Income. Due to the factors described above, net income for the Company
decreased $2.5 million to a loss of $2.1 million for 1995.

LIQUIDITY AND CAPITAL RESOURCES
 
  Funding for the Company's business activities has historically been provided
by operating cash flows, bank borrowings, reserve-based financing and sales of
equity. While the Company regularly engages in discussions relating to
potential acquisitions of oil and gas properties, well servicing businesses
and real estate properties, it has no present agreement, commitment or
understanding with respect to any such acquisition. Any future acquisitions
may require additional financing and will be dependent upon financing
arrangements available at the time.
 
  Net Cash Provided by Operating Activities. Cash flows provided by operating
activities from the Company's operations were $5.2 million, $5.6 million and
$10.3 million for 1994, 1995 and 1996, respectively. Increases in oil and gas
production and revenues resulting principally from acquisition and development
activities over this three-year period, as well as generally improved oil and
gas prices, increased cash flows. Additionally, growth from well servicing
acquisitions, increased cash flows, partially offset by cash used in real
estate operating activities. Cash flows from the Company's operations for the
nine-month period ended September 30, 1997 were $9.4 million, as compared to
$4.8 million for the prior year. This increase was primarily attributable to
increases in oil and gas production and prices and increased activity
attributable to well servicing and real estate acquisitions.
 
  Net Cash Used in Investing Activities. Cash flows used in investing
activities by the Company were $9.6 million, $44.5 million and $33.2 million
for 1994, 1995 and 1996, respectively. Acquisitions and oil and gas
development activities were the primary uses of funds. Cash flows used in
investing activities by the Company for the nine months ended September 30,
1996 were $12.5 million and for the nine months ended September 30, 1997 were
$62.7 million.
 
  The following table sets forth capital expenditures, including acquisitions,
made by the Company during the periods indicated.

  In 1997, the Company budgeted $102.7 million for oil and gas acquisition,
development and exploration, including $72.3 million for the Oil and Gas
Properties Acquisition. The Company actually spent $103.9 million in 1997 on
acquisition, development and exploration. The Company has budgeted $44.9
million for acquisition, development and exploration in 1998. In addition,
Sierra and Red Oak had budgeted $43.6 and $55.0 million, respectively, for
acquisitions and capital expenditures in 1997. Actual expenditures for 1997
were $61.4 million for Sierra and $53.8 for Red Oak. The Company anticipates
capital expenditures in 1998 of $1.3 million at Sierra and $4.0 million at Red
Oak.
 
  Net Cash Provided by Financing Activities. Cash provided by the Company's
financing activities was $5.1 million, $39.2 million (including additional
borrowings of $37.1 million) and $27.9 million (including additional
borrowings of $18.0 million and $9.9 million net proceeds from issuance of
additional equity securities) for 1994, 1995 and 1996, respectively. Cash
provided by financing activities for the Company's operations for the nine
months ended September 30, 1997 was $56.2 million, consisting of additional
net borrowings of $53.7 million and net proceeds from private equity sales by
a subsidiary.

  In April 1997, MROP, a wholly-owned subsidiary of Red Oak, entered into a
$42 million credit facility maturing in April 2000 with an institutional
lender (the "MROP Facility"). The MROP Facility was executed in order to
consolidate six mortgage loans, originally incurred to complete the
acquisition of certain Red Oak properties, and to finance the acquisition of
an additional real estate property. Borrowings under the facility bear
interest at a rate of 13%, with 10% payable in cash and the remaining 3%
payable in cash or additional notes at MROP's option. The facility contains a
number of covenants that, among other things, restrict the ability of MROP to
incur additional indebtedness and dispose of assets. The facility is secured
by a first lien on substantially all of MROP's properties. MROP's obligations
under the facility are nonrecourse to SRH, Southwest, Red Oak and Sierra.
 
  In conjunction with the Private Placement, the Company arranged new
borrowing facilities for each of its businesses. The following discussion
summarizes the material terms of such facilities.
 
  Southwest Credit Facility. The Southwest Credit Facility has been amended to
provide for a $75 million revolving line of credit maturing in February 1999,
resulting in availability of $40 million, subject to semi-annual borrowing
base redetermination. The initial borrowing base of $40 million is subject to
a $15 million sub-limit on availability for oil and gas acquisitions, with the
balance of the borrowing base available for general corporate purposes.
Borrowings accrue interest at LIBOR plus a margin ranging from 1.75% to 2.50%
and incur a quarterly commitment fee of three-eighths of one percent ( 3/8%)
per annum on the daily average of the unadvanced amount of the borrowing base.
The Southwest Credit Facility is secured by substantially all of Southwest's
proved oil and gas properties. The facility contains a number of covenants
that limit loans and advances, investments, and dividends, as well as setting
a minimum interest coverage ratio for SRH.
 
  Sierra Acquisition Facility. Sierra arranged the Sierra Acquisition
Facility, in the amount of $60 million, secured by all of Sierra's assets,
with an institutional lender. Tranche A of the Sierra Acquisition Facility is
for up to $30 million, with interest payable monthly at the prime rate plus
1.0%. The full amount of Tranche A was used to finance part of Sierra's recent
acquisitions and the related working capital and costs and expenses of such
transactions. Tranche B of the Sierra Acquisition Facility is for $30 million,
with an initial availability of $10 million and subsequent advances subject to
lender approval. Sierra spent $61.4 million for acquisitions and capital
expenditures in 1997. $50.0 million of those expenditures were funded from the
Sierra Acquisition Facility. Interest will be payable monthly on funds
advanced under Tranche B, initially at the prime rate plus 3.0%, subject to
adjustment. The final maturity of the Sierra Acquisition Facility is 18 months
after the date of closing of the facility. Under the terms of the Sierra
Acquisition Facility, the lender received certain fees and warrants to
purchase common stock of Sierra.
 
  Red Oak Acquisition Facilities. In order to partially fund Red Oak's recent
acquisitions, the MROP Facility was increased by an additional $30 million and
Red Oak entered into two additional mortgage facilities with separate lenders
(the "Red Oak Acquisition Facilities"). Red Oak spent $53.8 million for
acquisitions and capital expenditures in 1997. $51.1 million of those
expenditures were funded from the Red Oak Acquisition Facilities. The Red Oak
Acquisition Facilities are secured by a first lien on the properties acquired.
The two additional mortgage facilities contain a number of covenants that,
among other things, restrict the ability of Red Oak to incur additional
indebtedness and dispose of assets, and borrowings thereunder bear interest at
9.25%. Red Oak's obligations under the Red Oak Acquisition Facilities are
nonrecourse to SRH, Southwest and Sierra.
 
  To partially fund its recent acquisitions, Red Oak sold additional common
stock to SRH for $10 million. SRH funded its purchase of additional common
stock from the proceeds of a dividend of $10 million from Southwest, paid out
of a portion of the net proceeds from the Private Placement.
 
  The Company believes that availability under the Southwest Credit Facility,
the Sierra Acquisition Facility, the Red Oak Acquisition Facilities, cash flow
from operations and the proceeds from the private placement Note Offering,
will be sufficient for planned operating and capital expenditure requirements
in 1997 and 1998. If the Company makes capital expenditures in excess of
planned levels, it may be required to seek additional financing.

                                   BUSINESS
 
GENERAL
 
  The Company is an independent oil and gas company engaged in the
acquisition, development and production of oil and gas properties, primarily
in the Permian Basin of West Texas and southeastern New Mexico, through its
wholly-owned subsidiary, Southwest. Since 1983, the Company has grown
primarily through selective acquisitions of producing oil and gas properties,
completing over $320 million in acquisitions, both directly and through the
oil and gas partnerships it manages. The Company also participates in the well
servicing industry through its affiliate, Sierra, and owns and manages real
estate properties through its subsidiary, Red Oak.
 
  The Company pursues a strategy of acquiring long-life, producing oil and gas
properties, which offer both current cash flow, significant development
potential and opportunities to reduce operating and administrative costs. Many
of the Company's previous acquisitions were completed during periods of
relatively low oil and gas prices, and the Company generally deferred
development of such acquired properties to invest available capital in
additional acquisitions. Due to increased oil and gas prices and improved
availability of capital, the Company has increased its oil and gas development
activities. The Company plans to increase capital spending on development and
exploitation opportunities.
 
  At June 30, 1997, on a pro forma basis, the Company owned interests in
approximately $2.6 million gross leasehold acres, approximately 75% of which
were classified as developed. At such date, the Company's estimated net proved
reserves, on a pro forma basis, would have been 32.5 MMBbls of oil and 75.3
Bcf of natural gas, or 45.0 MMBoe. The Company's properties are located
primarily in the Permian Basin and generally have well-established production
histories with a pro forma reserve life of approximately 15 years. At June 30,
1997, the Company's pro forma PV-10 Value would have been $214.5 million.
 
  The Company's development projects generally involve moderate drilling and
completion costs as they are located primarily in shallow to intermediate
depth, normally pressured reservoirs. Additionally, many of these projects
contain multiple horizons that are potentially productive, thereby further
reducing development drilling risk. The Company has identified over 500
recompletion and development opportunities on its properties. For the nine
months ended September 30, 1997, Southwest has spent approximately $27 million
in the aggregate for oil and gas acquisition, development and exploration
activities and has budgeted additional capital spending of approximately $45
million for the remainder of 1997 and 1998 principally to complete over 190
planned development drilling and recompletion projects. The Company
anticipates that its development activities, when combined with new seismic
and other data, will result in the identification of additional development
drilling prospects and proved reserves.
 
  The Company engages in the well servicing business through Sierra, in which
SRH has a 26% direct ownership interest in Sierra as well as an indirect 10%
ownership interest through Southwest which is the general partner and 15%
interest holder in two partnerships which own approximately 64% of Sierra.
Sierra, which was formed in 1992, provides a broad range of well services to
oil and gas companies, including workover rig services, liquids handling and
other services. Since January 1996, Sierra has purchased 15 well servicing
companies for a total cost of $42.1 million, increasing its equipment fleet to
86 workover rigs. Management believes that Sierra is the fourth largest land-
based well servicing company in the United States.
 
  Red Oak, an 82%-owned subsidiary of SRH, on a pro forma basis, owns and
manages retail shopping centers and office buildings in Texas, Oklahoma and
Arizona. Since December 1993, Red Oak has acquired 17 properties for
approximately $82.8 million.
 
STRATEGY
 
  The Company's objective is to increase its revenues, cash flow, earnings and
assets through a balanced growth strategy of acquisition, development and
exploitation of oil and gas properties, and through its investments in the
well servicing and real estate businesses.

  Complete Selective Oil and Gas Acquisitions. The Company seeks to acquire
producing oil and gas properties that provide opportunities for the addition
of reserves, production and cash flow through operational improvements,
production enhancement and additional development. The Company believes these
criteria are met in the Permian Basin due to the region's long history of
production and multiple producing oil and gas horizons. The Company has
acquired over $320 million of oil and gas properties since inception, both
directly and through the oil and gas partnerships it manages. Management
believes that acquisition opportunities will continue to be available in the
Permian Basin.
 
  Develop and Exploit Existing Oil and Gas Properties. The Company has
acquired a diversified portfolio of oil and gas properties that contains
numerous identified development opportunities. The Company believes that
current oil and gas prices, combined with technical and operating advances,
have improved the attractiveness of accelerated development of these
properties. The Company plans to significantly increase its capital spending
during 1997 and 1998 to pursue these opportunities, which consist principally
of infill drilling, recompletions, enhanced recovery operations and workover
opportunities. The Company is pursuing these projects to increase cash flow
and to identify additional reserves and development projects.
 
  Maintain Geographic Focus. The Company concentrates its oil and gas
activities in the Permian Basin, with properties in this region representing
over 90% of the Company's pro forma PV-10 Value at June 30, 1997. The Company
believes that its long-life oil and gas properties and large inventory of
development projects in the Permian Basin, coupled with region-specific
geological, engineering and production experience, provide it with focused
operations. Company-operated properties comprised approximately 60% of its pro
forma PV-10 Value at June 30, 1997, allowing substantial control over the
incurrence and timing of capital and operating expenditures.
 
  Selectively Grow Well Servicing and Real Estate Businesses. The Company
plans to continue the expansion of its well servicing and real estate
businesses, primarily in the southwestern United States. The Company expects
that Sierra's and Red Oak's active management practices will lead to
consolidation benefits, cost savings, more efficient utilization and improved
cash flow, thereby enhancing the return on capital invested.
 
SOUTHWEST
 
  Prior to 1996, Southwest grew principally through the acquisition of
producing properties, establishing a substantial base of producing and
undeveloped properties in the Permian Basin. Due to relatively low oil and gas
prices, as well as certain other constraints, Southwest pursued limited
exploration and development of its properties during this period. With the
recovery of oil and gas prices, Southwest increased its development activities
in 1996. Southwest plans to accelerate the internal development and
exploitation projects. Southwest's development program focuses on its operated
properties. For the second half of 1997 and for 1998, Southwest has budgeted
capital spending for over 190 drilling and recompletion opportunities within
its existing property base, approximately 90% of which are identified as
proved in its reserve report. Southwest intends to devote a limited amount of
its capital spending to lower risk exploration drilling opportunities,
consisting principally of step-out drilling prospects adjacent to existing
producing fields.
 
  Southwest's estimated actual and pro forma net proved reserves as of June
30, 1997 were approximately 31.0 MMBoe and 45.0 MMBoe, respectively, and
actual and pro forma production during the first nine months of 1997 was
approximately 1.5 MMBoe and 2.1 MMBoe, respectively. Approximately 67% of the
pro forma reserves would have been classified as proved developed. As of June
30, 1997, Southwest's PV-10 Value, on a pro forma basis, would have been
$214.5 million.
 
 Principal Oil and Gas Properties
 
  The Company's oil and gas properties are primarily located in the Permian
Basin of West Texas and southeastern New Mexico. Approximately 86% of the
Company's PV-10 Value is concentrated in this region (91% on a pro forma
basis). The region is characterized by numerous known producing horizons,
providing
 
                                      43

significant opportunities to increase reserves, production and ultimate
recoveries through additional development, horizontal drilling, recompletions,
enhanced recovery methods, and the use of 3-D seismic, reprocessed 2-D seismic
data and other advanced technologies. As of June 30, 1997, the Company
operated properties comprising approximately 60% of its PV-10 Value (60% on a
pro forma basis). The following table provides information for the Company's
ten largest fields which contribute approximately 50% of its reserves and PV-
10 Value as of June 30, 1997.

 The Oil and Gas Properties Acquisition
 
  On October 14, 1997, the Company acquired various working interests in 431
producing oil and gas wells, located in seven fields in the Permian Basin of
West Texas and southeastern New Mexico. The Company will operate 133 of these
wells. The Company believes that it has significant opportunities to improve
production and cash flow from these properties through additional development,
reconfiguration of operations and reduction of operating and administrative
costs. These acquisitions added estimated net proved reserves of approximately
13.3 MMBbls of oil and 4.2 Bcf of gas, or 14.0 MMBoe, as of June 30, 1997. The
following table provides information for the seven fields included in the
acquisition, and the largest fields are described thereafter.

(1) Pro forma to reflect the Oil and Gas Properties Acquisition as if it had
    occurred on June 30, 1997.
(2) The present value of future net revenues attributable to Southwest's
    reserves was prepared using prices in effect at the end of the respective
    periods presented, discounted at 10% per annum on a pre-tax basis. Such
    amounts reflect the effects, if any, of the Company's hedging activities.
    See "--Oil and Natural Gas Marketing and Hedging."
(3) Discounted future cash flows, including taxes, are not intended to
    represent estimates of the fair value of oil and gas properties. Estimates
    of fair value should also consider probable reserves, anticipated future
    oil and gas prices, interest rates, changes in development and production
    costs and production costs and risks associated with future production.
    Because of these considerations, any estimate of fair value is necessarily
    subjective and imprecise.
 
  In accordance with applicable requirements of the Commission, estimates of
Southwest's proved reserves and future net revenues are made using oil and
natural gas sales prices estimated to be in effect as of the date of such
reserve estimates and are held constant throughout the life of the properties
(except to the extent a contract specifically provides for escalation). The
average prices used in the reserve report as of June 30, 1997, were $17.34 per
Bbl of oil and $2.16 per Mcf of natural gas, compared to average prices used
as of December 31, 1996 of $23.89 per Bbl of oil and $3.67 per Mcf of natural
gas.
 
  Estimated quantities of proved reserves and future net revenues therefrom
are affected by oil and natural gas prices, which have fluctuated widely in
recent years. There are numerous uncertainties inherent in estimating oil and
natural gas reserves and their values, including many factors beyond the
control of the producer. The reserve data set forth in this Prospectus
represent only estimates. Reservoir engineering is a subjective process of
estimating underground accumulations of oil and natural gas that cannot be
measured in an exact manner. The accuracy of any reserve estimate is a
function of the quality of available data and of engineering and geological
interpretation and judgment. As a result, estimates of different engineers,
including those used by Southwest, may vary. In addition, estimates of
reserves are subject to revision based upon actual production, results of
future development and exploration activities, prevailing oil and natural gas
prices, operating costs and other factors, which revisions may be material.
Accordingly, reserve estimates are often different from the quantities of oil
and natural gas that are ultimately recovered and are highly dependent upon
the accuracy of the assumptions upon which they are based.
 
                                      47
<PAGE>
 
  In general, the volume of production from oil and natural gas properties
declines as reserves are depleted. Except to the extent Southwest acquires
properties containing proved reserves or conducts successful exploration and
development activities, or both, the proved reserves of Southwest will decline
as reserves are produced. Southwest's future oil and natural gas production
is, therefore, highly dependent upon its level of success in finding or
acquiring additional reserves. See "Risk Factors--Replacement of Reserves" and
"--Uncertainty of Reserve Information and Future Net Revenue Estimates."

</TABLE>
 
  From October 1, 1997 through October 31, 1997, Southwest participated in
drilling activities on 12 gross wells. Of the 12 gross (3.3 net) wells, 4
gross (1.4 net) well have been completed as commercial producers, no wells
were dry holes and 8 gross (1.9 net) wells are currently being drilled.
 
 Oil and Natural Gas Marketing and Hedging
 
  The revenues generated by Southwest's operations are highly dependent upon
the prices of and demand for oil and natural gas. The price received by
Southwest for its oil and natural gas production depends on numerous factors
beyond Southwest's control. Historically, the markets for oil and natural gas
have been volatile and are likely to continue to be volatile in the future.
Prices for oil and natural gas are subject to wide fluctuation in response to
relatively minor changes in the supply and demand for oil and natural gas,
market uncertainty and a variety of additional factors. These factors include
the level of consumer product demand, weather conditions, domestic and foreign
governmental regulations, the price and availability of alternative fuels,
political conditions in the Middle East, the actions of OPEC, the foreign
supply of oil and natural gas and overall economic conditions. It is
impossible to predict future oil and natural gas price movements with any
certainty. Declines in oil and natural gas prices may adversely affect
Southwest's financial condition, liquidity, and results of operations. See
"Risk Factors--Volatility of Oil and Natural Gas Prices" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
  During 1996, Scurlock Permian Corporation purchased crude oil from Southwest
that contributed 13% of Southwest's oil revenue. Southwest does not believe
the loss of this purchaser would have a material adverse effect on its
operations, revenues or cash flow.
 
  All of Southwest's oil and natural gas production is currently sold at spot
market prices, under various short term and intermediate term contracts.
Southwest currently does not utilize commodity swap agreements or fixed price
arrangements to reduce its exposure to oil or natural gas price movements.
 
SIERRA
 
  Sierra provides a broad range of services used by oil and gas companies in
Texas and New Mexico, including workover rig services, liquids handling, fresh
and brine water supply and disposal and other services. Sierra's workover rig
services include the completion of newly drilled wells, the recompletion and
maintenance of existing wells and the plugging and abandonment of wells at the
end of their useful life. Complementary services include liquids handling
services and fresh and brine water supply and disposal services. SRH currently
owns, directly and indirectly, approximately a 40% interest in Sierra.
 
                                      49
<PAGE>
 
  Sierra's strategy emphasizes diversification and expansion through the
acquisition of well servicing companies and internal growth in order to
provide an integrated group of oil field services. Sierra is a participant in
the consolidation of the well servicing industry and believes that the highly
fragmented well servicing market will continue to provide attractive
acquisition opportunities.
 
  From January 1996 through November 30, 1997, Sierra completed 17
acquisitions of well servicing companies for an aggregate cost of $58.9
million. In total, these acquisitions added 64 well servicing rigs, 134
trucks, 279 frac and test tanks, 32 brine and/or fresh water stations, eight
injection wells and various related equipment. However, there can be no
assurance that such acquisitions will occur as expected in December or ever.
Sierra believes it has been generally successful in acquiring well servicing
companies and assets, subsequently reducing overhead expenses and improving
the marketing, utilization and efficiency of its growing asset base.
 
 Well Servicing
 
  Sierra uses its well servicing rigs to provide completion, maintenance,
workover and plugging and abandonment services to major and independent oil
and gas companies. Ancillary equipment such as pumps, tanks, blowout
preventers and power swivels are provided by Sierra as may be required for a
particular job. Sierra also provides trucking services for moving large
equipment to and from the job sites of its customers. Sierra generally charges
its customers an hourly rate for its well services, which varies based on
numerous considerations including market conditions in each region, the type
of rig, the amount of ancillary equipment required and the necessary
personnel.
 
  Well services are classified by type of job performed and are generally
categorized as completion, maintenance, workover, recompletion or plugging and
abandonment. Completion services involve the preparation of a newly drilled
well for production and generally involve the installation of permanent
equipment. Maintenance services are required on producing wells to ensure
efficient and continuous operation and generally involve routine mechanical
repairs. Workover and recompletion services involve major repairs and
modifications to existing wells and include extension of existing wells to new
formations, accessing previously bypassed productive zones and conversion of
producing wells to water injection wells. Workover rigs are also used in the
plugging and abandonment of oil and natural gas wells no longer capable of
producing economic quantities.
 
  As of December 5, 1997, Sierra operated 86 land-based well servicing rigs
and ancillary equipment from 9 yards in Texas and New Mexico.
 Liquids Handling Services
 
  Sierra provides liquids handling services, comprised of vacuum truck
services, frac tank rentals and test tank rentals. After the pending
transactions have been completed in December 1997, Sierra will own 134 vacuum
and transport trucks. A vacuum truck is a tractor trailer with a fluid hauling
capacity of up to 130 barrels. A large vacuum pump mounted on each truck
extracts fluids from pits, tanks and other storage facilities. Vacuum trucks
are used to transport water to fill frac tanks, to transport produced salt
water to injection wells and to transport drilling and completion fluids to
and from well locations.
 
                                      50
<PAGE>
 
  After the pending acquisitions have been completed in December 1997, Sierra
will own 235 frac tanks. Each frac tank can store up to 500 barrels of fluid
and is used by oil field operators to store various fluids at the well site,
including water, drilling mud, acid and brine. Frac tanks are used during all
phases of the life of a producing well and are generally rented on a daily
basis.
 
  Sierra will own 44 test tanks after the pending acquisitions. Each test tank
can store up to 250 barrels of fluid and is used by oil field operators to
store various well bore fluids at the well site during the testing of
production of oil wells. Test tanks are rented on a four-day minimum plus any
additional days needed by the operator. Sierra also charges for delivery, set-
up and removal of the test tanks.
 
  Sierra will also own 90 Enviro-Vat systems, the patent for their production
and the right to royalties created by the sale of these systems to other
operators. The Enviro-Vat is a unitized, trailer mounted system that connects
to the well-head to catch normal oil and other liquid spills that occur during
regular maintenance, workovers and completions. Sierra believes that the
Enviro-Vat system will be a profitable addition to its existing well servicing
business as companies increase efforts to minimize the impact of their
operations on the environment.
 
 Fresh and Brine Water Supply and Disposal Services
 
  Sierra provides fresh and brine water supply and disposal services,
including injection wells and fresh water and brine stations.
 
  After the pending acquisitions have been completed in December 1997, Sierra
will own or lease eight injection wells that are authorized to dispose of salt
water and incidental non-hazardous oil and gas wastes. These wells are
strategically located in close proximity to customers' producing oil and gas
wells. Sierra maintains separation equipment at each of its injection wells,
permitting it to salvage residual crude oil which is later sold for Sierra's
account.
 
  After the pending acquisitions have been completed in December 1997, Sierra
owns 32 brine and/or fresh water stations which are used to supply water
necessary for the drilling and completion of oil and gas wells. This
complementary business gives Sierra an advantage over certain competitors for
water sales and the associated transportation and expands Sierra's customer
base.
 
  Other Services
 
  Sierra provides other well services, including pit lining and hot oil
services. Pit lining services consist of excavating, preparing and eventually
closing a pit used during the drilling or completion of oil and gas wells for
the collection of fluids such as drilling mud, other well bore fluids and
fresh water. Hot oil services consist of pumping hot oil into a gathering line
or well tubing to melt paraffin and asphaltines that solidify and restrict
production. Sierra intends to acquire and subsequently offer additional well
services and products that are complementary to its well servicing strategy.
 
RED OAK
 
  Red Oak was formed by the Company in 1992 to acquire and manage neighborhood
and community shopping centers, other retail and commercial properties and
office buildings. These properties are primarily leased, on a long-term basis,
to major retail companies, local specialty retailers and professional and
business tenants throughout secondary urban markets in the southwestern United
States. As of October 31, 1997, Red Oak owned and managed 14 shopping centers,
three office buildings and raw land held for future development.
 
  Red Oak's primary objective is to acquire, own and manage a portfolio of
commercial properties that provides opportunity to increase net operating
income and results in significant capital appreciation. Consistent with this
strategy, Red Oak focuses its activities primarily in secondary markets in the
southwestern United States, including San Antonio, Midland, San Angelo, El
Paso, and Corpus Christi in Texas; Reno, Nevada; Tucson, Arizona; and Tulsa
and Oklahoma City, Oklahoma. Red Oak believes that the potential for
population growth in these markets and a lower level of interest from
institutional real estate buyers, as compared to primary markets, result in
attractive acquisition opportunities of multi-tenant, income producing
properties ranging in purchase price from $1 million to $20 million.
 
                                      51
<PAGE>
 
Recent Acquisitions
 
  From December 1993 through October 31, 1997, Red Oak completed the
acquisition of 14 regional shopping centers and three office buildings for a
total acquisition cost of $82.8 million. Red Oak has financed and expects to
continue to finance the acquisition of its real estate properties with senior
secured credit arrangements between Red Oak and private lenders, that are
generally non-recourse to the Company. Red Oak believes that as a result of
minor capital investment and limited releasing activities, the performance of
these properties will improve in a manner consistent with Red Oak's historical
experience. Red Oak's existing property portfolio is shown in the table below.

  The aforementioned properties were acquired from unrelated third parties.
Prior to each acquisition, the Company performs various due diligence
procedures including, but not limited to, evaluation of competition in the
rental market, comparative rents, occupancy rates, related operating expenses,
cash flow and anticipated capital expenditures. The Company believes the
historical operating results of the properties acquired are indicative of
future operating results for each respective acquisition.
 
EMPLOYEES
 
  As of September 30, 1997, the Company employed 497 people. Of this total,
123 people were employed by Southwest, 359 by Sierra, and 15 by Red Oak. The
Company's future success will depend partially on its ability to attract,
retain and motivate qualified personnel. The Company is not a party to any
collective bargaining agreements and has not experienced any strikes or work
stoppages. The Company considers its relations with its employees to be
satisfactory.
 
COMPETITION
 
  The oil and natural gas industry is highly competitive. The Company's oil
and gas business competes for the acquisition of oil and natural gas
properties, primarily on the basis of the price to be paid for such
properties, with numerous entities including major oil companies, other
independent oil and natural gas concerns and individual producers and
operators. Many of these competitors are large, well established companies and
have financial and other resources substantially greater than those of the
Company's oil and gas business. The Company's ability to acquire additional
oil and gas properties and to discover reserves in the future will depend
 
                                      52
<PAGE>
 
upon its ability to evaluate and select suitable properties and to consummate
transactions in a highly competitive environment.
 
  Competition is intense in all markets in which the Company's businesses
operate. Surplus capacity in the well servicing industry has resulted in price
being the primary means of competition. Pool Energy Services Co., Key Energy
Group, Inc. and Dawson Production Services, Inc., all of which provide
workover rig and liquids handling services, are the largest companies in the
domestic well servicing market. These companies operate in multiple geographic
regions and are larger than the Company's well servicing business. The
Company's well servicing business competes on the basis of pricing,
performance, safety, availability of equipment to meet customer needs and
availability of experienced, skilled personnel in those areas in which it
operates. Several competitors have access to greater financial and other
resources than those of the Company's well servicing business. The Company's
real estate business also competes for the acquisition of desirable commercial
real estate properties, primarily on the basis of price.
 
OPERATING HAZARDS AND RISKS
 
  The oil and natural gas business involves a variety of operating risks,
including the risk of fire, explosions, blow outs, pipe failure, abnormally
pressured formations and environmental hazards such as oil spills, gas leaks,
ruptures or discharges of toxic gases. Any of these occurrences could result
in substantial losses to the Company due to injury or loss of life, severe
damage to or destruction of property, natural resources and equipment,
environmental damage, clean-up responsibilities, regulatory investigation and
penalties and suspension of operations.
 
  Drilling activities are subject to many risks, including the risk that no
commercially productive reservoirs will be encountered. There can be no
assurance that new wells drilled by the Company will be productive or that the
Company will recover all or any portion of its investment. Drilling for oil
and gas may involve unprofitable efforts, not only from dry wells, but from
wells that are productive but do not produce sufficient net revenues to return
a profit after drilling, operating or other costs. The cost of drilling,
completing and operating wells is often uncertain. The Company's drilling
operations may be curtailed, delayed or canceled as a result of numerous
factors, many of which are beyond the Company's control, including title
problems, weather conditions, mechanical problems, compliance with
governmental requirements and shortages and delays in the delivery of
equipment and services. The Company's future drilling activities may not be
successful and, if unsuccessful, such failure may have a material adverse
effect on the Company's future results of operations and financial condition.
 
  The Company's well servicing operations are also subject to hazards inherent
in the oil and gas industry, such as blowouts, explosions, craterings, fires
and oil spills, that can cause personal injury or loss of life, damage to or
destruction of property, equipment, the environment, and suspension of
operations. In addition, claims for loss of oil and gas production and damage
to formations can occur in the workover business. If a serious accident were
to occur at a location where Sierra's equipment and services are used, it
could result in the Company or Sierra being named as a defendant in a lawsuit
asserting potentially large claims. Additionally, because Sierra's vacuum
trucks and frac/test tank rentals involve the transport of heavy equipment and
materials, traffic accidents resulting in spills, property damage and personal
injury may occur.
 
  Although the Company maintains insurance coverage considered to be customary
in each industry in which it participates, it is not fully insured against
certain risks, either because insurance is not available or because of the
high premium costs. The Company's real estate business carries business
interruption insurance. The Company does maintain physical damage, employer's
liability, comprehensive commercial general liability and workers'
compensation insurance. There can be no assurance that any insurance obtained
by the Company will be adequate to cover any losses or liabilities, or that
such insurance will continue to be available or available on terms which are
acceptable to the Company.
 
LEGAL PROCEEDINGS
 
  From time to time, the Company is party to litigation or other legal
proceedings that each company considers to be a part of the ordinary course of
its business. The Company is not involved in any legal proceedings nor is it
party to any pending or threatened claims that could reasonably be expected to
have a material adverse effect on its financial condition or results of
operations.

REGULATION
 
  General. Various aspects of the Company's oil and natural gas operations are
subject to extensive and continually changing regulation, as legislation
affecting the oil and natural gas industry is under constant review for
amendment or expansion. Numerous departments and agencies, both federal and
state, are authorized by statute to issue, and have issued, rules and
regulations binding upon the oil and natural gas industry and its individual
members. The Federal Energy Regulatory Commission ("FERC") regulates the
transportation and sale for resale of natural gas in interstate commerce
pursuant to the Natural Gas Act of 1938 ("NGA") and the Natural Gas Policy Act
of 1978 ("NGPA"). In the past, the Federal government has regulated the prices
at which oil and natural gas could be sold. While sales by producers of
natural gas and all sales of crude oil, condensate and natural gas liquids can
currently be made at uncontrolled market prices, Congress could reenact price
controls in the future. Deregulation of wellhead sales in the natural gas
industry began with the enactment of the NGPA in 1978. In 1989, Congress
enacted the Natural Gas Wellhead Decontrol Act (the "Decontrol Act"). The
Decontrol Act removed all remaining NGA and NGPA price and nonprice controls
affecting wellhead sales of natural gas effective January 1, 1993.
 
  Regulation of Sales and Transportation of Natural Gas. The Company's sales
of natural gas are affected by the availability, terms and cost of
transportation. The price and terms for access to pipeline transportation are
subject to extensive regulation. In recent years, the FERC has undertaken
various initiatives to increase competition within the natural gas industry.
As a result of initiatives like FERC Order No. 636, issued in April 1992, the
interstate natural gas transportation and marketing system has been
substantially restructured to remove various barriers and practices that
historically limited non-pipeline natural gas sellers, including producers,
from effectively competing with interstate pipelines for sales to local
distribution companies and large industrial and commercial customers. The most
significant provisions of Order No. 636 require that interstate pipelines
provide firm and interruptible transportation service on an open access basis
that is equal for all natural gas supplies. In many instances, the results of
Order No. 636 and related initiatives have been to substantially reduce or
eliminate the interstate pipelines' traditional role as wholesalers of natural
gas in favor of providing only storage and transportation services. While the
United States Court of Appeals upheld most of Order No. 636 last year, certain
related FERC orders, including the individual pipeline restructuring
proceedings, are still subject to judicial review and may be reversed or
remanded in whole or in part. While the outcome of these proceedings cannot be
predicted with certainty, the Company does not believe that it will be
affected materially differently than its competitors.
 
  The FERC has also announced several important transportation-related policy
statements and proposed rule changes, including a statement of policy and a
request for comments concerning alternatives to its traditional cost-of-
service ratemaking methodology to establish the rates interstate pipelines may
charge for their services. A number of pipelines have obtained FERC
authorization to charge negotiated rates as one such alternative. In February
1997, the FERC announced a broad inquiry into issues facing the natural gas
industry to assist the FERC in establishing regulatory goals and priorities in
the post-Order No. 636 environment. Similarly, the Texas Railroad Commission
has been reviewing changes to its regulations governing transportation and
gathering services provided by intrastate pipelines and gatherers. While the
changes being considered by these federal and state regulators would affect
the Company only indirectly, they are intended to further enhance competition
in natural gas markets. The Company cannot predict what further action the
FERC or state regulators will take on these matters, however, the Company does
not believe that it will be affected by any action taken materially
differently than other natural gas producers with which it competes.
 
  Additional proposals and proceedings that might affect the natural gas
industry are pending before Congress, the FERC, state commissions and the
courts. The natural gas industry historically has been very heavily regulated;
therefore, there is no assurance that the less stringent regulatory approach
recently pursued by the FERC and Congress will continue.
 
  Oil Price Controls and Transportation Rates. Sales of crude oil, condensate
and gas liquids by the Company are not currently regulated and are made at
market prices. The price the Company receives from the sale of these products
may be affected by the cost of transporting the products to market.
 
                                      54

  Environmental. Extensive federal, state and local laws regulating the
discharge of materials into the environment or otherwise relating to the
protection of the environment affect Southwest's oil and natural gas
operations and Sierra's well servicing activities. Numerous governmental
departments issue rules and regulations to implement and enforce such laws,
which are often difficult and costly to comply with and which carry
substantial civil and even criminal penalties for failure to comply. Some
laws, rules and regulations relating to protection of the environment may, in
certain circumstances, impose strict liability for environmental
contamination, rendering a person liable for environmental damages and cleanup
costs without regard to negligence or fault on the part of such person. Other
laws, rules and regulations may restrict the rate of oil and natural gas
production below the rate that would otherwise exist or even prohibit
exploration and production activities in sensitive areas. In addition, state
laws often require various forms of remedial action to prevent pollution, such
as closure of inactive pits and plugging of abandoned wells. The regulatory
burden on the oil and natural gas industry, including the well servicing
industry, increases the Company's cost of doing business and consequently
affects the Company's profitability. The Company believes that it is in
substantial compliance with current applicable environmental laws and
regulations and that continued compliance with existing requirements will not
have a material adverse impact on the Company's operations. However,
environmental laws and regulations have been subject to frequent changes over
the years, and the imposition of more stringent requirements could have a
material adverse effect upon the capital expenditures, earnings or competitive
position of the Company.
 
  In addition, Red Oak's real estate management activities are subject to
federal, state and local laws, rules and regulations pertaining to protection
of the environment which may, in certain circumstances, impose strict
liability for environmental contamination, thus rendering Red Oak liable for
environmental damages and clean up costs without regard to negligence or fault
on the part of Red Oak. Asbestos-containing materials may be present at Red
Oak's real estate holdings which may dictate costly remediation to abate
asbestos or which may increase the cost of renovations to property when they
become necessary. Further, activities on adjacent properties, such as dry
cleaning, gasoline retailing, and automobile maintenance, may result in
subsurface soil and groundwater contamination that could impair Red Oak's use
or sale of real estate holdings or cause Red Oak to incur costs to remediate
any contamination caused by activities of lessors or adjacent properties.
 
  The Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA") imposes liability, without regard to fault on certain classes of
persons that are considered to be responsible for the release of a "hazardous
substance" into the environment. These persons include the current or former
owner or operator of the disposal site or sites where the release occurred and
companies that disposed or arranged for the disposal of hazardous substances.
Under CERCLA such persons may be subject to joint and several liability for
the costs of investigating and cleaning up hazardous substances that have been
released into the environment, for damages to natural resources and for the
costs of certain health studies. In addition, companies that incur liability
frequently also confront third party claims because it is not uncommon for
neighboring landowners and other third parties to file claims for personal
injury and property damage allegedly caused by hazardous substances or other
pollutants released into the environment from a polluted site.
 
  The Federal Solid Waste Disposal Act, as amended by the Resource
Conservation and Recovery Act of 1976 ("RCRA"), regulates the generation,
transportation, storage, treatment and disposal of hazardous wastes and can
require cleanup of hazardous waste disposal sites. RCRA currently excludes
drilling fluids, produced waters and other wastes associated with the
exploration, development or production of oil and natural gas from regulation
as "hazardous waste." Disposal of such non-hazardous oil and natural gas
exploration, development and production wastes usually are regulated by state
law. Other wastes handled at exploration and production sites or used in the
course of providing well services may not fall within this exclusion.
Moreover, stricter standards for waste handling and disposal may be imposed on
the oil and natural gas industry in the future. From time to time legislation
is proposed in Congress that would revoke or alter the current exclusion of
exploration, development and production wastes from the RCRA definition of
"hazardous wastes" thereby potentially subjecting such wastes to more
stringent handling, disposal and cleanup requirements. If such legislation
were
 
                                      55
<PAGE>
 
enacted it could have a significant impact on the operating costs of Southwest
and Sierra, as well as the oil and natural gas industry and well servicing
industry in general. The impact of future revisions to environmental laws and
regulations cannot be predicted.
 
  The Company's operations are also subject to the Clean Air Act ("CAA") and
comparable state and local requirements. Amendments to the CAA were adopted in
1990 and contain provisions that may result in the gradual imposition of
certain pollution control requirements with respect to air emissions from
operations of Southwest and/or Sierra. Southwest and/or Sierra may be required
to incur certain capital expenditures in the next several years for air
pollution control equipment in connection with obtaining and maintaining
operating permits and approvals for air emissions. However, neither Southwest
nor Sierra believes its operations will be materially adversely affected by
any such requirements, and the requirements are not expected to be any more
burdensome to Southwest or to Sierra than to other similarly situated
companies involved in oil and natural gas exploration and production
activities or well servicing activities.
 
  Southwest maintains insurance against "sudden and accidental" occurrences
which may cover some, but not all, of the risks described above. Most
significantly, the insurance maintained by Southwest will not cover the risks
described above which occur over a sustained period of time. Further, there
can be no assurance that such insurance will continue to be available to cover
all such costs or that such insurance will be available at premium levels that
justify its purchase. Sierra also maintains insurance against certain risks
associated with underground contamination that may occur as a result of well
service activities. However, such insurance is limited to activities at the
wellsite and there can be no assurance that such insurance will continue to be
available to cover all such costs or that such insurance will be available at
premium levels that justify its purchase. The occurrence of a significant
event not fully insured or indemnified against could have a material adverse
effect on Southwest's financial condition and operations.
 
  Regulation of Oil and Natural Gas Exploration and Production. Exploration
and production operations of the Company are subject to various types of
regulation at the federal, state and local levels. Such regulations include
requiring permits and drilling bonds for the drilling of wells, regulating the
location of wells, the method of drilling and casing wells, and the surface
use and restoration of properties upon which wells are drilled. Many states
also have statutes or regulations addressing conservation matters, including
provisions for the utilization or pooling of oil and natural gas properties,
the establishment of maximum rates of production from oil and natural gas
wells and the regulation of spacing, plugging and abandonment of such wells.
Some state statutes limit the rate at which oil and natural gas can be
produced from Southwest's properties. See "Risk Factors--Compliance with
Governmental Regulations."
 
TITLE TO PROPERTIES
 
  The Company believes it has satisfactory title to all of its properties in
accordance with standards generally accepted in the oil and gas, well
servicing and real estate industries. As is customary in the oil and natural
gas industry, Southwest makes only a cursory review of title to farmout
acreage and to undeveloped oil and natural gas leases upon execution of any
contracts. Prior to the commencement of drilling operations, a thorough title
examination is conducted and curative work is performed with respect to
significant defects. To the extent title opinions or other investigations
reflect title defects, Southwest, rather than the seller of the undeveloped
property, is typically responsible to cure any such title defects at its
expense. If Southwest were unable to remedy or cure any title defect of a
nature such that it would not be prudent to commence drilling operations on
the property, Southwest could suffer a loss of its entire investment in the
property. Southwest has obtained title opinions on substantially all of its
producing properties and believes that it has satisfactory title to such
properties in accordance with standards generally accepted in the oil and
natural gas industry. Prior to completing an acquisition of producing oil and
natural gas leases, Southwest obtains title opinions on all leases.
Southwest's oil and natural gas properties are subject to customary royalty
interests, liens for current taxes and other burdens that Southwest believes
do not materially interfere with the use of or affect the value of such
properties.

  On December 15, 1994, H. H. Wommack, III borrowed approximately $1.7 million
on an unsecured basis from Southwest for the purpose of purchasing the
Southwest common stock held by a certain stockholder. The note held by
Southwest was amended on March 15, 1995 to include $35,225 of accrued but
unpaid interest. The note carries a 6% interest rate and is being amortized
over 30 years with payments of $5,500 semi-monthly. As of September 30, 1997,
the outstanding balance of this loan was $1.7 million. Mr. Wommack serves as a
general partner of substantially all of the oil and gas limited partnerships
sponsored by Southwest since 1983, and he holds an interest in these
partnerships of approximately 1%.

                                EXCHANGE OFFER
 
  In connection with the sale of the Old Notes, the purchasers thereof became
entitled to the benefits of certain registration rights under the Registration
Rights Agreement. The Exchange Notes are being offered hereunder in order to
satisfy the obligations of the Issuer and SRH under the Registration Rights
Agreement. See "Exchange and Registration Rights Agreement."
 
  For each $1,000 principal amount of Old Notes surrendered to the Issuer and
SRH pursuant to the Exchange Offer, the holder of such Old Notes will receive
$1,000 principal amount of Exchange Notes. Upon the terms and subject to the
conditions set forth in this Prospectus and in the accompanying Letter of
Transmittal, SRH and the Issuer will accept all Old Notes properly tendered
prior to 5:00 p.m., New York City time, on the Expiration Date. Holders may
tender some or all of their Old Notes pursuant to the Exchange Offer in
integral multiples of $1,000 principal amount.
 
  Under existing interpretations of the staff of the SEC, including EXXON
CAPITAL HOLDINGS CORPORATION, SEC No-action Letter (available April 13, 1989),
the Morgan Stanley Letter and MARY KAY COSMETICS, INC., SEC No-action Letter
(available June 5, 1991), the Issuer and SRH believe that the Exchange Notes
would in general be freely transferable after the Exchange Offer without
further registration under the Securities Act by the respective holders
thereof (other than a "Restricted Holder," being (i) a broker-dealer who
purchased Old Notes exchanged for such Exchange Notes directly from the Issuer
to resell pursuant to Rule 144A or any other available exemption under the
Securities Act or (ii) a person that is an affiliate of the Issuer or SRH
within the meaning of Rule 405 under the Securities Act), without compliance
with the registration and prospectus delivery provisions of the Securities
Act, provided that such Exchange Notes are acquired in the ordinary course of
such holder's business and such holder is not participating in, and has no
arrangement with any person to participate in, the distribution (within the
meaning of the Securities Act) of such Exchange Notes. Eligible holders
wishing to accept the Exchange Offer must represent to the Issuer and SRH that
such conditions have been met. Any holder of Old Notes who tenders in the
Exchange Offer for the purpose of participating in a distribution of the
Exchange Notes could not rely on the interpretation by the staff of the SEC
enunciated in the Morgan Stanley Letter and similar no-action letters, and
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction.
 
  Each holder of Old Notes who wishes to exchange Old Notes for Exchange Notes
in the Exchange Offer will be required to make certain representations,
including that (i) it is not an affiliate of the Issuer or SRH nor a broker-
dealer tendering Old Notes acquired directly from the Issuer or SRH for its
own account, (ii) any Exchange Notes to be received by it are being acquired
in the ordinary course of its business and (iii) it is not participating in,
and it has no arrangement with any person to participate in, the distribution
(within the meaning of the Securities Act) of the Exchange Notes. In addition,
in connection with any resales of Exchange Notes, any broker-dealer (a
"Participating Broker-Dealer") who acquired Old Notes for its own account as a
result of market-making activities or other trading activities must
acknowledge that it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such Exchange Notes. The staff
of the SEC has taken the position in no-action letters issued to third parties
including SHEARMAN & STERLING, SEC No-action Letter (available July 2, 1993),
that Participating Broker-Dealers may fulfill their prospectus delivery
requirements with respect to the Exchange Notes (other than a resale of an
unsold allotment from the original sale of Old Notes) with this Prospectus, as
it may be amended or supplemented from time to time. Under the Registration
Rights Agreement, the Issuer and SRH are required to allow Participating
Broker-Dealers to use this Prospectus, as it may be amended or supplemented
from time to time, in connection with the resale of such Exchange Notes. See
"Plan of Distribution."
 
  The Exchange Offer shall be deemed to have been consummated upon the earlier
to occur of (i) the Issuer and SRH having exchanged Exchange Notes for all
outstanding Old Notes (other than Old Notes held by a Restricted Holder)
pursuant to the Exchange Offer and (ii) the Issuer and SRH having exchanged,
pursuant to the Exchange Offer, Exchange Notes for all Old Notes that have
been tendered and not withdrawn on the
 
                                      62
<PAGE>
 
Expiration Date. In such event, holders of Old Notes seeking liquidity in
their investment would have to rely on exemptions to registration requirements
under the securities laws, including the Securities Act.
 
  As of the date of this Prospectus, $200,000,000 aggregate principal amount
of Old Notes are issued and outstanding. In connection with the issuance of
the Old Notes, the Issuer and SRH arranged for the Old Notes to be eligible
for trading in the Private Offering, Resale and Trading through Automated
Linkages (PORTAL) Market, the National Association of Securities Dealers'
screen based, automated market trading of securities eligible for resale under
Rule 144A.
 
  The Issuer and SRH shall be deemed to have accepted for exchange validly
tendered Old Notes when, as and if the Issuer and SRH have given oral or
written notice thereof to the Exchange Agent. See "--Exchange Agent." The
Exchange Agent will act as agent for the tendering holders of Old Notes for
the purpose of receiving Exchange Notes from the Issuer and delivering
Exchange Notes to such holders. If any tendered Old Notes are not accepted for
exchange because of an invalid tender or the occurrence of certain other
events set forth herein, certificates for any such unaccepted Old Notes will
be returned, without expense, to the tendering holder thereof as promptly as
practicable after the Expiration Date. Holders of Old Notes who tender in the
Exchange Offer will not be required to pay brokerage commissions or fees or,
subject to the instructions in the Letter of Transmittal, transfer taxes with
respect to the exchange of Old Notes pursuant to the Exchange Offer. The
Issuer and SRH will pay all charges and expenses, other than certain
applicable taxes, in connection with the Exchange Offer. See "--Fees and
Expenses."
 
  This Prospectus, together with the accompanying Letter of Transmittal, is
being sent to all registered holders as of the date of this Prospectus.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The term "Expiration Date" shall mean 30 days after the effective date of
the Registration Statement. 1998 unless the Issuer and SRH, in their sole
discretion, extend the Exchange Offer, in which case the term "Expiration
Date" shall mean the latest date to which the Exchange Offer is extended. In
order to extend the Expiration Date, the Issuer and SRH will notify the
Exchange Agent of any extension by oral or written notice and will mail to the
record holders of Old Notes an announcement thereof, each prior to 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
Expiration Date. Such announcement may state that SRH and the Issuer are
extending the Exchange Offer for a specified period of time. The Issuer and
SRH reserve the right (i) to delay acceptance of any Old Notes, to extend the
Exchange Offer or to terminate the Exchange Offer and to refuse to accept Old
Notes not previously accepted, if any of the conditions set forth herein under
"--Termination" shall have occurred and shall not have been waived by the
Issuer and SRH (if permitted to be waived by the Issuer and SRH), by giving
oral or written notice of such delay, extension or termination to the Exchange
Agent, and (ii) to amend the terms of the Exchange Offer in any manner deemed
by it to be advantageous to the holders of the Old Notes. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly
as practicable by oral or written notice thereof. If the Exchange Offer is
amended in a manner determined by the Issuer and SRH to constitute a material
change, the Issuer and SRH will promptly disclose such amendment in a manner
reasonably calculated to inform the holders of the Old Notes of such
amendment. Without limiting the manner in which the Issuer and SRH may choose
to make public announcements of any delay in acceptance, extension,
termination or amendment of the Exchange Offer, the Issuer and SRH shall have
no obligation to publish, advertise, or otherwise communicate any such public
announcement, other than by making a timely release to the Dow Jones News
Service.
 
INTEREST ON THE EXCHANGE NOTES
 
  The Exchange Notes will bear interest at the rate of 10 1/2% per annum,
payable semi-annually on April 15 and October 15 of each year, commencing on
April 15, 1998. Interest on the Exchange Notes will accrue from (A) the later
of (i) the last interest payment date on which interest was paid on the Notes
surrendered in exchange therefor; or (ii) if the Notes are surrendered for
exchange on a date in a period which includes the record date for
 
                                      63
<PAGE>
 
an interest payment date to occur on or after the date of such exchange and as
to which interest will be paid, the date of such interest payment date or (B)
if no interest has been paid on the Notes, from the date of the original
issuance of the Notes, October 14, 1997. Interest on the Old Notes accepted
for exchange will cease to accrue upon issuance of the Exchange Notes.
 
PROCEDURES FOR TENDERING
 
  To tender in the Exchange Offer, a holder must complete, sign and date the
Letter of Transmittal, or a facsimile thereof, have the signatures thereon
guaranteed if required by the Letter of Transmittal, and mail or otherwise
deliver such Letter of Transmittal or such facsimile, or an Agent's Message,
together with the Old Notes and any other required documents, to the Exchange
Agent prior to 5:00 p.m., New York City time, on the Expiration Date. In
addition, either (i) the certificates for such Old Notes must be received by
the Exchange Agent along with the Letter of Transmittal or (ii) a timely
confirmation of a book-entry transfer (a "Book-Entry Confirmation") of such
Old Notes, if such procedure is available, into the Exchange Agent's account
at The Depository Trust Company (the "DTC") pursuant to the procedure for
book-entry transfer described below, must be received by the Exchange Agent
along with an Agent's Message prior to the Expiration Date or (iii) the Holder
must comply with the guaranteed delivery procedures described below. The
tender by a holder of Old Notes will constitute an agreement between such
holder and the Issuer and SRH in accordance with the terms and subject to the
conditions set forth herein and in the Letter of Transmittal.
 
  Delivery of all documents must be made to the Exchange Agent at its address
set forth herein. Holders may also request that their respective brokers,
dealers, commercial banks, trust companies or nominees effect such tender for
such holders.
 
  The term "Agent's Message" means a message, transmitted by the DTC to, and
received by, the Exchange Agent and forming a part of a Book-Entry
Confirmation, which states that such DTC has received an express
acknowledgment from the participant in such DTC tendering Old Notes which are
the subject of such Book-Entry Confirmation that such participant has received
and agrees to be bound by the terms of the Letter of Transmittal, and that the
Issuer and SRH may enforce such agreement against such participant.
 
  The method of delivery of Old Notes and the Letter of Transmittal and all
other required documents to the Exchange Agent is at the election and risk of
the holders. Instead of delivery by mail, it is recommended that holders use
an overnight or hand delivery service. In all cases, sufficient time should be
allowed to assure timely delivery. No Letter of Transmittal or Old Notes
should be sent to the Issuer or SRH. Only a holder of Old Notes may tender
such Old Notes in the Exchange Offer. The term "holder" with respect to the
Exchange Offer means any person in whose name Old Notes are registered on the
books of the Issuer or any other person who has obtained a properly completed
stock power from the registered holder.
 
  Any beneficial holder whose Old Notes are registered in the name of such
holder's broker, dealer, commercial bank, trust company or other nominee and
who wishes to tender should contact such registered holder promptly and
instruct such registered holder to tender on behalf of the registered holder.
If such beneficial holder wishes to tender directly, such beneficial holder
must, prior to completing and executing the Letter of Transmittal and
delivering his Old Notes, either make appropriate arrangements to register
ownership of the Old Notes in such holder's name or obtain a properly
completed bond power from the registered holder. The transfer of record
ownership may take considerable time. If the Letter of Transmittal is signed
by the record holder(s) of the Old Notes tendered thereby, the signature must
correspond with the name(s) written on the face of the Old Notes without
alteration, enlargement or any change whatsoever. If the Letter of Transmittal
is signed by a participant in DTC, the signature must correspond with the name
as it appears on the security position listing as the holder of the Old Notes.
Signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by a member firm of a registered national
securities exchange or of the National Association of Securities Dealers,
Inc., a commercial bank or trust company having an office or correspondent in
the United States or an "eligible guarantor institution" within the meaning of
Rule 17Ad-15 under the Exchange Act (an
 
                                      64
<PAGE>
 
"Eligible Institution") unless the Old Notes tendered pursuant thereto are
tendered (i) by a registered holder (or by a participant in DTC whose name
appears on a security position listing as the owner) who has not completed the
box entitled "Special Issuance Instructions" or "Special Delivery
Instructions" on the Letter of Transmittal and the Exchange Notes are being
issued directly to such registered holder (or deposited into the participant's
account at DTC) or (ii) for the account of an Eligible Institution. If the
Letter of Transmittal is signed by a person other than the registered holder
of any Old Notes listed therein, such Old Notes must be endorsed or
accompanied by appropriate bond powers which authorize such person to tender
the Old Notes on behalf of the registered holder, in either case signed as the
name of the registered holder or holders appears on the Old Notes. If the
Letter of Transmittal or any Old Notes or bond powers are signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by Issuer and SRH,
evidence satisfactory to the Issuer and SRH of their authority to so act must
be submitted with the Letter of Transmittal.
 
  A tender will be deemed to have been received as of the date when the
tendering holder's duly signed Letter of Transmittal accompanied by Old Notes
(or a timely confirmation received of a book-entry transfer of Old Notes into
the Exchange Agent's account at DTC with an Agent's Message) or a Notice of
Guaranteed Delivery from an Eligible Institution is received by the Exchange
Agent. Issuances of Exchange Notes in exchange for Old Notes tendered pursuant
to a Notice of Guaranteed Delivery by an Eligible Institution will be made
only against delivery of the Letter of Transmittal (and any other required
documents) and the tendered Old Notes (or a timely confirmation received of a
book-entry transfer of Old Notes into the Exchange Agent's account at DTC with
an Agent's Message) with the Exchange Agent.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of the tendered Old Notes will be
determined by the Issuer and SRH in their sole discretion, which determination
will be final and binding. The Issuer and SRH reserve the absolute right to
reject any and all Old Notes not properly tendered or any Old Notes their
acceptance of which would, in the opinion of the Issuer and SRH or its
counsel, be unlawful. The Issuer and SRH also reserve the absolute right to
waive any conditions of the Exchange Offer or defects or irregularities in
tender as to particular Old Notes. The Issuer and SRH's interpretation of the
terms and conditions of the Exchange Offer (including the instructions in the
Letter of Transmittal) shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Old Notes
must be cured within such time as the Issuer and SRH shall determine. Neither
the Issuer, SRH, the Exchange Agent nor any other person shall be under any
duty to give notification of defects or irregularities with respect to tenders
of Old Notes nor shall any of them incur any liability for failure to give
such notification. Tenders of Old Notes will not be deemed to have been made
until such irregularities have been cured or waived. Any Old Notes received by
the Exchange Agent that are not properly tendered and as to which the defects
or irregularities have not been cured or waived will be returned without cost
by the Exchange Agent to the tendering holder of such Old Notes unless
otherwise provided in the Letter of Transmittal, as soon as practicable
following the Expiration Date. In addition, the Issuer and SRH reserves the
right in their sole discretion to (i) purchase or make offers for any Old
Notes that remain outstanding subsequent to the Expiration Date, or, as set
forth under "--Termination," to terminate the Exchange Offer and (ii) to the
extent permitted by applicable law, purchase Old Notes in the open market, in
privately negotiated transactions or otherwise. The terms of any such
purchases or offers may differ from the terms of the Exchange Offer.
 
BOOK-ENTRY TRANSFER
 
  The Exchange Agent will establish an account with respect to the Exchange
Notes at DTC within two business days after the date of this Prospectus, and
any financial institution which is a participant in DTC may make book-entry
delivery of the Old Notes by causing DTC to transfer such Old Notes into the
Exchange Agent's account in accordance with DTC's procedure for such transfer.
Although delivery of Old Notes may be effected through book-entry transfer
into the Exchange Agent's account at DTC, an Agent's Message must be
transmitted to and received by the Exchange Agent on or prior to the
Expiration Date at one of its addresses set forth below under "--Exchange
Agent," or the guaranteed delivery procedure described below must be
 
                                      65
<PAGE>
 
complied with. DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO
THE EXCHANGE AGENT. All references in this Prospectus to deposit or delivery
of Old Notes shall be deemed to include DTC's book-entry delivery method.
 
GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their Old Notes and whose Old Notes are not
immediately available or who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent prior to the
Expiration Date, or who cannot complete the procedure for book-entry transfer
on a timely basis and deliver an Agent's Message, may effect a tender if: (i)
the tender is made by or through an Eligible Institution; (ii) prior to the
Expiration Date, the Exchange Agent receives from such Eligible Institution a
properly completed and duly executed Notice of Guaranteed Delivery (by
facsimile transmission, mail or hand delivery) setting forth the name and
address of the holder of the Old Notes, the registration number or numbers of
such Old Notes (if applicable), and the total principal amount of Old Notes
tendered, stating that the tender is being made thereby and guaranteeing that,
within five business days after the Expiration Date, the Letter of
Transmittal, together with the Old Notes in proper form for transfer (or a
confirmation of a book-entry transfer into the Exchange Agent's account at DTC
with an Agent's Message) and any other documents required by the Letter of
Transmittal, will be deposited by the Eligible Institution with the Exchange
Agent; and (iii) such properly completed and executed Letter of Transmittal,
together with the certificate(s) representing all tendered Old Notes in proper
form for transfer (or a confirmation of such a book-entry transfer) and all
other documents required by the Letter of Transmittal are received by the
Exchange Agent within five business days after the Expiration Date.
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
  The Letter of Transmittal contains, among other things, certain terms and
conditions which are summarized below and are part of the Exchange Offer.
 
  Each holder who participates in the Exchange Offer will be required to
represent that any Exchange Notes received by it will be acquired in the
ordinary course of its business, that such holder is not participating in, and
has no arrangement with any person to participate in, the distribution (within
the meaning of the Securities Act) of the Exchange Notes, and that such holder
is not a Restricted Holder.
 
  Old Notes tendered in exchange for Exchange Notes (or a timely confirmation
of a book-entry transfer of such Old Notes into the Exchange Agent's account
at DTC) must be received by the Exchange Agent, with the Letter of Transmittal
or an Agent's Message and any other required documents, by the Expiration Date
or within the time periods set forth above pursuant to a Notice of Guaranteed
Delivery from an Eligible Institution. Each holder tendering the Old Notes for
exchange sells, assigns and transfers the Old Notes to the Exchange Agent, as
agent of the Issuer, and irrevocably constitutes and appoints the Exchange
Agent as the holder's agent and attorney-in-fact to cause the Old Notes to be
transferred and exchanged. The holder warrants that it has full power and
authority to tender, exchange, sell, assign and transfer the Old Notes and to
acquire the Exchange Notes issuable upon the exchange of such tendered Old
Notes, that the Exchange Agent, as agent of the Issuer, will acquire good and
unencumbered title to the tendered Old Notes, free and clear of all liens,
restrictions, charges and encumbrances, and that the Old Notes tendered for
exchange are not subject to any adverse claims when accepted by the Exchange
Agent, as agent of the Issuer.
 
  The holder also warrants and agrees that it will, upon request, execute and
deliver any additional documents deemed by the Issuer, the SRH or the Exchange
Agent to be necessary or desirable to complete the exchange, sale, assignment
and transfer of the Old Notes. All authority conferred or agreed to be
conferred in the Letter of Transmittal by the holder will survive the death,
incapacity or dissolution of the holder and any obligation of the holder shall
be binding upon the heirs, personal representatives, successors and assigns of
such holder.
 
WITHDRAWAL OF TENDERS
 
  Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the business day prior
to the Expiration Date, unless previously accepted for exchange.
 
                                      66
<PAGE>
 
To withdraw a tender of Old Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to 5:00 p.m., New York City time,
on the business day prior to the Expiration Date and prior to acceptance for
exchange thereof by the Issuer and SRH. Any such notice of withdrawal must (i)
specify the name of the person having deposited the Old Notes to be withdrawn
(the "Depositor"), (ii) identify the Old Notes to be withdrawn (including, if
applicable, the registration number or numbers and total principal amount of
such Old Notes), (iii) be signed by the Depositor in the same manner as the
original signature on the Letter of Transmittal by which such Old Notes were
tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to permit the Trustee with respect to the Old
Notes to register the transfer of such Old Notes into the name of the
Depositor withdrawing the tender, (iv)specify the name in which any such Old
Notes are to be registered, if different from that of the Depositor and (v) if
applicable because the Old Notes have been tendered pursuant to the book-entry
procedures, specify the name and number of the participant's account at DTC to
be credited, if different than that of the Depositor. All questions as to the
validity, form and eligibility (including time of receipt) of such withdrawal
notices will be determined by the Issuer and SRH, whose determination shall be
final and binding on all parties. Any Old Notes so withdrawn will be deemed
not to have been validly tendered for purposes of the Exchange Offer and no
Exchange Notes will be issued with respect thereto unless the Old Notes so
withdrawn are validly retendered. Any Old Notes which have been tendered but
which are not accepted for exchange will be returned to the holder thereof
without cost to such holder as soon as practicable after withdrawal, rejection
of tender or termination of the Exchange Offer. Properly withdrawn Old Notes
may be retendered by following one of the procedures described above under "--
Procedures for Tendering" at any time prior to the Expiration Date.
 
TERMINATION
 
  Notwithstanding any other term of the Exchange Offer, SRH and the Issuer
will not be required to accept for exchange any Old Notes not theretofore
accepted for exchange, and may terminate the Exchange Offer if they determine
that the Exchange Offer violates any applicable law or interpretation of the
staff of the SEC.
 
  If the Issuer and SRH determine that they may terminate the Exchange Offer,
as set forth above, the Issuer and SRH may (i) refuse to accept any Old Notes
and return any Old Notes that have been tendered to the holders thereof, (ii)
extend the Exchange Offer and retain all Old Notes tendered prior to the
Expiration of the Exchange Offer, subject to the rights of such holders of
tendered Old Notes to withdraw their tendered Old Notes or (iii) waive such
termination event with respect to the Exchange Offer and accept all properly
tendered Old Notes that have not been withdrawn. If such waiver constitutes a
material change in the Exchange Offer, the Issuer and SRH will disclose such
change by means of a supplement to this Prospectus that will be distributed to
each registered holder of Old Notes, and the Issuer and SRH will extend the
Exchange Offer for a period of five to ten business days, depending upon the
significance of the waiver and the manner of disclosure to the registered
holders of the Old Notes, if the Exchange Offer would otherwise expire during
such period. Holders of Old Notes will have certain rights against the Issuer
and SRH under the Registration Agreement should the Issuer and SRH fail to
consummate the Exchange Offer.

<PAGE>
 
FEES AND EXPENSES
 
  The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by the Issuer and SRH. The principal solicitation for tenders pursuant
to the Exchange Offer is being made by mail. Additional solicitations may be
made by officers and regular employees of the Issuer and SRH in person, by
telegraph or telephone. The Issuer and SRH will not make any payments to
brokers, dealers or other persons soliciting acceptances of the Exchange
Offer. The Issuer and SRH, however, will pay the Exchange Agent reasonable and
customary fees for its services and will reimburse the Exchange Agent for its
reasonable out-of-pocket expenses in connection therewith. The Issuer and SRH
may also pay brokerage houses and other custodians, nominees and fiduciaries
the reasonable out-of-pocket expenses incurred by them in forwarding copies of
this Prospectus, Letters of Transmittal and related documents to the
beneficial owners of the Old Notes and in handling or forwarding tenders for
exchange.
 
  The other expenses incurred in connection with the Exchange Offer, including
fees and expenses of the Exchange Agent and Trustee and accounting and legal
fees, will be paid by the Issuer and SRH. The Issuer and SRH will pay all
transfer taxes, if any, applicable to the exchange of Old Notes pursuant to
the Exchange Offer. If, however, Exchange Notes or Old Notes not tendered or
accepted for exchange are to be delivered to, or are to be registered or
issued in the name of, any person other than the registered holder of the Old
Notes tendered, or if tendered Old Notes are registered in the name of any
person other than the person signing the Letter of Transmittal, or if a
transfer tax is imposed for any reason other than the exchange of Old Notes
pursuant to the Exchange Offer, then the amount of any such transfer taxes
(whether imposed on the registered holder or any other persons) will be
payable by the tendering holder. If satisfactory evidence of payment of such
taxes or exemption therefrom is not submitted with the Letter of Transmittal,
the amount of such transfer taxes will be billed directly to such tendering
holder.
 
ACCOUNTING TREATMENT
 
  No gain or loss for accounting purposes will be recognized by the Issuer or
SRH upon the consummation of the Exchange Offer. The expenses of the Exchange
Offer will be amortized by the Issuer over the term of the Exchange Notes
under generally accepted accounting principles.

                             DESCRIPTION OF NOTES
 
  The Old Notes were issued and the Exchange Notes will be issued pursuant to
an indenture, dated October 14, 1997 (the "Indenture"), by and among
Southwest, as Issuer, SRH, as the Parent Guarantor, and State Street Bank and
Trust Company, N.A., as Trustee (the "Trustee"). References to the "Notes"
shall include the "Exchange Notes" except where the context otherwise
requires. The Indenture is governed by certain provisions contained in the
Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The terms
of the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act. The following summaries of
certain provisions of the Notes, the Indenture and the Security Documents do
not purport to be complete and are subject to, and are qualified in their
entirety by reference to all of the provisions of the Indenture or the
Security Documents, as applicable. A copy of the form of the Indenture, the
Registration Rights Agreement and each of the Security Documents is available
from the Issuer upon request. Capitalized terms used herein, and not otherwise
defined herein, have the meanings defined under the heading "Certain
Definitions." Other capitalized terms not otherwise defined herein have the
meanings assigned to them in the Indenture.
 
  The Notes will be issued in full registered form only, without coupons, in
denominations of $1,000 and integral multiples thereof. Initially, the Trustee
will act as Paying Agent and Registrar for the Notes. The Notes may be
presented for registration of transfer and exchange at the offices of the
Registrar, which currently is the Trustee's corporate trust office in
Hartford, Connecticut. The Issuer may change the Paying Agent and Registrar
without notice to Holders of the Notes. The Issuer will pay principal
(premium, if any) and interest on the Notes at the corporate trust offices of
the Trustee or its agency in New York, New York. In addition, in the event the
Notes do not remain in book-entry form, interest may be paid, at the Issuer's
option, by wire transfer or check mailed to the registered addresses of the
Holders as shown on the Note Register.
 
  As of the Issue Date, the Issuer is a Restricted Subsidiary of SRH, the
Parent Guarantor of the Notes. As of the Issue Date, Red Oak will be an
Unrestricted Subsidiary of SRH. Subject to the requirements of the Indenture,
SRH will be able to designate future Subsidiaries as Unrestricted
Subsidiaries. Unrestricted Subsidiaries will not be subject to the restrictive
covenants set forth in the Indenture.
 
  Any Notes that remain outstanding after the completion of this Offer,
together with the Exchange Notes issued in connection with this Offer, will be
treated as a single class of securities under the Indenture.
 
  Under certain circumstances, the obligations of the Issuer under the Notes
may be guaranteed in the future by other Restricted Subsidiaries of SRH. See
"--Ranking and Guarantees."
 
PRINCIPAL, MATURITY AND INTEREST
 
  The Notes will be limited in aggregate principal amount to $200 million and
will mature on October 15, 2004. Interest on the Notes will accrue at the rate
of 10 1/2% per annum and will be payable semi-annually on each April 15 and
October 15 commencing on April 15, 1998 to the Persons who are registered
Holders at the close of business on April 1 and October 1 immediately
preceding the applicable interest payment date. Interest on the Notes will
accrue from and including the most recent date to which interest has been paid
or, if no interest has been paid, from and including the Issue Date. Interest
will be computed on the basis of a 360-day year comprised of twelve 30-day
months.

OPTIONAL REDEMPTION
 
  The Issuer does not have the right to redeem the Notes prior to October 15,
2001. Thereafter, the Issuer may redeem the Notes, at its option, in whole or
in part, at any time, at the following redemption prices (expressed as a
percentage of the outstanding principal amount) if redeemed during the twelve-
month period commencing on October 15 of the year set forth below, plus, in
each case, accrued and unpaid interest thereon to the date of redemption:

      YEAR                                                              PRICE

</TABLE>
 
  Notwithstanding the foregoing, at any time on or prior to October 15, 2000,
the Issuer may redeem up to $70 million of the aggregate principal amount of
the Notes in cash at a redemption price equal to 110.50% of the principal
amount of the Notes so redeemed, together with accrued and unpaid interest
thereon to the redemption date, with the net proceeds of any Public Equity
Offering, provided that at least $130 million in aggregate principal amount of
the Notes remains outstanding immediately after the occurrence of such
redemption and provided further that such redemption occurs within 60 days of
the date of the closing of such Public Equity Offering.
 
 Selection and Notice
 
  In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee in compliance with the requirements of the
principal national securities exchange, if any, on which the Notes are listed,
or if the Notes are not listed, on a pro rata basis, by lot or by such other
method as the Trustee shall deem fair and appropriate, provided that no Note
of $1,000 or less shall be redeemed in part. Notice of redemption will be sent
by first class mail, at least 30 days and not more than 60 days prior to the
date fixed for redemption, to the Holder of each Note to be redeemed to such
Holder's last address as then shown upon the Note Register. Any notice which
relates to a Note to be redeemed in part only must state the portion of the
principal amount to be redeemed and must state that on and after the date
fixed for redemption, upon surrender of such Note, a new Note in a principal
amount equal to the unredeemed portion thereof will be issued. On and after
the date fixed for redemption, unless the Issuer defaults on its payment
obligations, interest will cease to accrue on the Notes or portions thereof
called for redemption.
 
RANKING AND GUARANTEES
 
  The indebtedness of the Issuer evidenced by the Notes ranks senior in right
of payment to all Subordinated Indebtedness of the Issuer and pari passu in
right of payment with all existing and future senior Indebtedness of the
Issuer. Pursuant to the Parent Guarantee, SRH unconditionally guarantees on a
senior basis, to each Holder and the Trustee, the full and prompt performance
of the Issuer's obligations under the Indenture and the Notes, including the
payment of principal of, premium, if any, and interest on the Notes. The
Parent Guarantee ranks pari passu in right of payment to all existing and
future senior Indebtedness of SRH. The Parent Guarantee is secured by pledges
of the Capital Stock of Sierra and Red Oak directly owned by SRH. See "--
Collateral." The Notes, the Parent Guarantee and the Subsidiary Guarantees are
effectively subordinated, however, to any secured Indebtedness of the Issuer,
SRH and the Subsidiary Guarantors to the extent of the collateral therefor,
including any Indebtedness under the Southwest Credit Facility, which is
secured by substantially all of the Issuer's oil and gas properties. As of
September 30, 1997, SRH and the Issuer would have had $1.5 million of senior
Indebtedness outstanding, excluding the Notes and the Parent Guarantee. See
"Capitalization."
 
  The Indenture also provides that each Significant Subsidiary of SRH (other
than the Issuer), whether now existing or hereafter formed or acquired,
becomes a Subsidiary Guarantor either by execution of the Indenture or a
supplemental indenture and thereby guarantee the Notes as described herein. In
addition, the Indenture provides that each Restricted Subsidiary (other than
the Issuer) which Incurs any Indebtedness (other than to SRH or the
 
                                      70
<PAGE>
 
Issuer) shall, within 10 days following the Incurrence of such Indebtedness,
become a Subsidiary Guarantor by execution of a supplemental indenture and
thereby guarantee the Notes as described herein. As of the Issue Date, there
will be no Subsidiary Guarantor.
 
  Each Subsidiary Guarantor will unconditionally guarantee on a senior
unsecured basis, jointly and severally, to each Holder and the Trustee, the
full and prompt performance of the Issuer's obligations under the Indenture
and the Notes, including the payment of principal of, premium, if any, and
interest on the Notes. The Subsidiary Guarantee of each Subsidiary Guarantor
will rank pari passu in right of payment to all existing and future senior
Indebtedness of such Subsidiary Guarantor.
 
  The obligation of each Subsidiary Guarantor is limited to the maximum amount
which, after giving effect to all other contingent and fixed liabilities of
such Subsidiary Guarantor and after giving effect to any collections from or
payments made by or on behalf of any other Subsidiary Guarantor in respect of
the obligations of such other Subsidiary Guarantor under its Subsidiary
Guarantee or pursuant to its contribution obligations under the Indenture,
will result in the obligations of such Subsidiary Guarantor under the
Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent
transfer under applicable federal or state law. SRH and each Subsidiary
Guarantor that makes a payment or distribution under the Parent Guarantee or a
Subsidiary Guarantee shall be entitled to a contribution from each other
Guarantor in a pro rata amount, based on the net assets of SRH and each
Subsidiary Guarantor, determined in accordance with GAAP. See "Risk Factors--
Possible Limitations on Enforceability of Subsidiary Guarantees."
 
  The Indenture provides that, subject to the following paragraph, each
Subsidiary Guarantor (including any existing or future Restricted Subsidiary
that becomes a Subsidiary Guarantor) may not consolidate or merge with or into
(whether or not such Subsidiary Guarantor is the surviving Person) another
Person or sell or convey all or substantially all of its assets to another
Person or group unless (i) the Person formed by or surviving any such
consolidation or merger (if other than such Subsidiary Guarantor) or the
transferee entity (A) is a corporation organized and existing under the laws
of the United States of America, any state thereof, or the District of
Columbia and (B) expressly assumes all the obligations of such Subsidiary
Guarantor pursuant to a supplemental indenture, in a form satisfactory to the
Trustee, under the Notes and the Indenture, (ii) immediately before and after
giving effect to such transaction, no Default or Event of Default exists and
immediately after giving effect to such transaction, the resulting surviving
or transferee entity could Incur $1.00 of additional Indebtedness (other than
Permitted Indebtedness) pursuant to paragraph (i) of the covenant described
herein under the caption "Limitation on Incurrences of Additional Indebtedness
and Issuances of Disqualified Capital Stock," and (iii) such Subsidiary
Guarantor or the Person formed by or surviving any such consolidation or
merger or the transferee entity on a pro forma basis will have Net Worth
(immediately after the transaction) equal to or greater than the Net Worth of
such Subsidiary Guarantor immediately preceding the transaction. The foregoing
does not apply to a merger, consolidation, sale or other such transaction
between Subsidiary Guarantors, between the Issuer and any Subsidiary Guarantor
or between SRH and any Subsidiary Guarantor.
 
  The Indenture provides that in the event of (i) the designation of any
Subsidiary Guarantor as an Unrestricted Subsidiary or (ii) a sale or other
disposition of all or substantially all of the properties or assets of any
Subsidiary Guarantor to a third party or an Unrestricted Subsidiary, by way of
merger, consolidation or otherwise, or a sale or other disposition of all of
the Capital Stock of any Subsidiary Guarantor, in either case, in a
transaction or manner that does not violate any of the covenants in the
Indenture, then such Subsidiary Guarantor (in the event of such a designation
or a sale or other disposition, by way of such a merger, consolidation or
otherwise, or a disposition of all of the Capital Stock of such Subsidiary
Guarantor) or the Person acquiring such properties or assets (in the event of
a sale or other disposition of all or substantially all of the properties or
assets of such Subsidiary Guarantor) will be released from and relieved of any
obligations under its Subsidiary Guarantee, provided that any Net Cash
Proceeds of such sale or other disposition are applied in accordance with the
covenant described under the caption "--Covenants--Limitation on Asset Sales,"
and provided, further, however, that any such termination shall occur only to
the extent that all obligations of such Subsidiary Guarantor under all of its
guarantees of, and under all of its pledges of assets or other security
interests that secure, any other Indebtedness of SRH or its Restricted
Subsidiaries shall also terminate upon such release, sale or disposition.

REPURCHASE OF NOTES AT THE OPTION OF THE HOLDER UPON A CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, each Holder has the right, at
such Holder's option, subject to the terms and conditions of the Indenture, to
require the Issuer to repurchase all or any part of such Holder's Notes
(provided that the principal amount of such Notes must be $1,000 or an
integral multiple thereof) on a date that is no later than 60 Business Days
after the occurrence of such Change of Control (the date on which the
repurchase is effected being referred to herein as the "Change of Control
Payment Date"), at a cash purchase price equal to 101% of the principal amount
thereof (the "Change of Control Purchase Price"), plus accrued and unpaid
interest thereon to the Change of Control Payment Date.
 
  The Issuer shall notify the Trustee within five Business Days after each
date upon which a Change of Control has occurred. Within 20 Business Days
after the occurrence of each Change of Control, the Issuer will make an
irrevocable, unconditional offer (a "Change of Control Offer") to the Holders
of Notes to purchase all of the Notes at the Change of Control Purchase Price,
plus accrued and unpaid interest thereon to the Change of Control Payment
Date, by sending written notice of a Change of Control Offer, by first class
mail, to each Holder at its registered address, with a copy to the Trustee.
The notice to Holders will contain all instructions and materials required by
applicable law and will contain or make available to Holders other information
material to such Holders' decision to tender Notes pursuant to the Change of
Control Offer.
 
  On or before the Change of Control Payment Date, the Issuer will, to the
extent lawful, (i) accept for payment Notes or portions thereof properly
tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying
Agent an amount sufficient to pay the Change of Control Purchase Price of all
Notes so tendered, and (iii) deliver or cause to be delivered to the Trustee
all Notes so accepted, together with an officers' certificate listing the
Notes or portions thereof being purchased by the Issuer. The Paying Agent will
promptly mail to the Holders of Notes so accepted payment in an amount equal
to the Change of Control Purchase Price for such Notes, plus accrued and
unpaid interest thereon to the Change of Control Payment Date, and the Trustee
will promptly cancel all Notes so accepted by the Issuer pursuant to the
Change of Control Offer and authenticate and mail (or cause to be transferred
by book entry) to such Holders a new Note equal in principal amount, as
applicable, to any unpurchased portion of the Note surrendered. Any Notes not
so accepted will be promptly mailed by the Issuer to the Holder thereof. The
Issuer will publicly announce the results of the Change of Control Offer on or
as soon as practicable after the Change of Control Purchase Date.
 
  The Change of Control provisions described above are applicable whether or
not any other provisions of the Indenture are applicable. Except as described
above with respect to a Change of Control, the Indenture does not contain
provisions that permit the Holders to require that the Issuer repurchase or
redeem the Notes in the event of a takeover, recapitalization or other similar
transaction of SRH or the Issuer. The provisions of the Indenture may not
afford Holders protection in the event of a highly leveraged transaction,
reorganization, restructuring, merger or other similar transaction affecting
SRH or the Issuer that may adversely affect the Holders if such transaction is
not the type of transaction included within the definition of "Change of
Control." A transaction involving the management of SRH, the Issuer or any
Affiliate or a transaction involving a recapitalization of SRH or the Issuer
will result in a Change of Control only if it is the type of transaction
specified in such definition.
 
  The existence of a Holder's right to require the Issuer to repurchase Notes
in connection with a Change of Control may deter a third party from acquiring
SRH or the Issuer in a transaction that would constitute a Change of Control.
 
  The source of funds for any repurchase of Notes upon a Change of Control
will be the Company's cash or cash generated from operation or other sources,
including borrowings or sales of assets; however, there can be no assurance
that sufficient funds will be available at the time of any Change of Control
to repay all Indebtedness owing or to make any required repurchase of the
Notes. Any failure by the Issuer to repurchase Notes tendered pursuant to a
Change of Control Offer will constitute an Event of Default. See "--Events of
Default and Remedies."
 
 
                                      72
<PAGE>
 
  The Issuer will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set
forth in the Indenture applicable to a Change of Control Offer made by the
Issuer and repurchases all Notes validly tendered and not withdrawn under such
Change of Control Offer.
 
  The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of (i) SRH and its Restricted Subsidiaries, taken as a whole, or
(ii) the Issuer. Although there is a developing body of judicial opinions
interpreting the phrase "all or substantially all," no precise standard exists
under New York law, which is the law governing the Indenture and the Notes.
Accordingly, the ability of a Holder of Notes to require the Issuer to
repurchase such Notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of the assets of (i) SRH and its Restricted
Subsidiaries, taken as a whole, or (ii) the Issuer, to another Person or group
is uncertain.
 
  To the extent applicable and if required by law, SRH and the Issuer will
comply with Section 14 of the Exchange Act, the provisions of Regulation 14E
and any other tender offer rules under the Exchange Act and other securities
laws, rules, and regulations which may then be applicable to any offer by the
Issuer to repurchase the Notes at the option of Holders upon a Change of
Control; and, if such laws, rules, and regulations require or prohibit any
action inconsistent with the foregoing, compliance by SRH and the Issuer with
such laws, rules, and regulations will not constitute a breach of the Issuer's
obligations with respect to the foregoing.
 
COVENANTS
 
  The Indenture contains, among others, the following covenants:
 
 Limitation on Incurrences of Additional Indebtedness and Issuances of
Disqualified Capital Stock
 
  The Indenture provides that SRH may not, and may not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, assume,
guarantee, or otherwise become liable for, contingently or otherwise (to
"Incur" or, as appropriate, an "Incurrence"), any Indebtedness or issue any
Disqualified Capital Stock, except that SRH or a Restricted Subsidiary may
Incur Indebtedness and SRH or the Issuer may issue shares of Disqualified
Capital Stock if:
 
    (i) the Consolidated Fixed Charge Coverage Ratio for SRH's Reference
  Period for which internal financial statements are available immediately
  preceding the date on which such additional Indebtedness is Incurred or
  such Disqualified Capital Stock is issued would have been (A) at least 2.0
  to 1.0 if such additional Indebtedness is Incurred or such Disqualified
  Capital Stock is issued during the period commencing on the Issue Date and
  ending on December 31, 1998 or (B) at least 2.5 to 1.0 if such additional
  Indebtedness is Incurred or such Disqualified Capital Stock is issued at
  any time thereafter;
 
    (ii) no Default or Event of Default shall have occurred and be continuing
  at the time such additional Indebtedness is Incurred or such Disqualified
  Capital Stock is issued or would occur as the result of such Incurrence of
  such additional Indebtedness or the issuance of such Disqualified Capital
  Stock; and
 
    (iii) SRH's Adjusted Consolidated Net Tangible Assets are equal to or
  greater than 150% of the consolidated Indebtedness of SRH and its
  Restricted Subsidiaries.
 
Notwithstanding the foregoing, if no Default or Event of Default shall have
occurred and be continuing at the time or as a consequence of the Incurrrence
of such Indebtedness, SRH and any Restricted Subsidiary may Incur Permitted
Indebtedness.
 
  Any Indebtedness Incurred or Disqualified Capital Stock issued by any Person
that is not a Subsidiary of SRH or any of its Restricted Subsidiaries, as the
case may be, which Indebtedness or Disqualified Capital Stock is outstanding
at the time such Person becomes a Restricted Subsidiary of, or is merged into,
or consolidated with SRH or such Restricted Subsidiary, as the case may be,
shall be deemed to have been Incurred or issued, as the case may be, at the
time such Person becomes a Restricted Subsidiary of, or is merged into, or
consolidated with SRH or such Restricted Subsidiary.
 
                                      73

 Limitation on Restricted Payments
 
  (a) The Indenture provides that SRH will not, and will not permit any
Restricted Subsidiary to, directly or indirectly (i) declare or pay any
dividend on, or make any other distribution to holders of, any shares of
Capital Stock of SRH or any Restricted Subsidiary (other than dividends or
distributions payable solely in shares of Qualified Capital Stock of SRH or
any Restricted Subsidiary or dividends or distributions payable to SRH or the
Issuer or any wholly-owned Restricted Subsidiary of SRH or the Issuer or
warrants, rights or options to acquire Qualified Capital Stock of SRH or any
Restricted Subsidiary), (ii) purchase, redeem or otherwise acquire or retire
for value any such shares of Capital Stock of SRH or any Affiliate (other than
any Capital Stock owned by SRH or any of its wholly-owned Restricted
Subsidiaries), or any options, warrants or other rights to acquire such
Capital Stock, (iii) make any principal payment on or repurchase, redeem,
defease or otherwise acquire or retire for value, prior to any scheduled
principal payment, scheduled sinking fund payment or maturity, any
Subordinated Indebtedness, or (iv) make any Restricted Investment (such
payments or other actions described in clauses (i) through (iv) being
collectively referred to as a "Restricted Payment"), unless at the time of and
after giving effect to the proposed Restricted Payment (the amount of any such
Restricted Payment, if other than cash, shall be the amount determined by the
Board of Directors of SRH, whose determination shall be conclusive and
evidenced by a Board Resolution),
 
  (1) no Default or Event of Default shall have occurred and be continuing,
 
  (2) SRH could incur $1.00 of additional Indebtedness (other than Permitted
Indebtedness) in accordance with clause (i) of the covenant "--Limitation on
Incurrences of Additional Indebtedness and Issuances of Disqualified Capital
Stock," and
 
  (3) the aggregate amount of all Restricted Payments declared or made after
the Issue Date shall not exceed the sum (without duplication) of the
following:
 
    (A) 50% of the Adjusted Consolidated Net Income of SRH accrued on a
  cumulative basis during the period commencing with the first full quarter
  after the Issue Date and ending on the last day of SRH's last fiscal
  quarter ending prior to the date of such proposed Restricted Payment (or if
  Adjusted Consolidated Net Income is a loss, minus 100% of such loss), plus
 
    (B) the aggregate Net Proceeds received after the Issue Date by SRH or
  the Issuer from the issuance or sale (other than to any of its Restricted
  Subsidiaries) of shares of Qualified Capital Stock of SRH or the Issuer or
  any options, warrants or rights to purchase such shares of Qualified
  Capital Stock of SRH or the Issuer, plus
 
    (C) the aggregate Net Proceeds received after the Issue Date by SRH or
  the Issuer (other than from any of its Restricted Subsidiaries) upon the
  exercise of any options, warrants or rights to purchase shares of Qualified
  Capital Stock of SRH or the Issuer, plus
 
    (D) the aggregate Net Proceeds received after the Issue Date by SRH or
  the Issuer from the issuance or sale (other than to any of its Restricted
  Subsidiaries) of Indebtedness or shares of Disqualified Capital Stock that
  have been converted into or exchanged for Qualified Capital Stock of SRH or
  the Issuer, together with the aggregate cash received by SRH or the Issuer
  at the time of such conversion or exchange, minus
 
    (E) the amount of any write-downs, writeoffs, other negative
  revaluations, and other negative extraordinary charges not otherwise
  reflected in Adjusted Consolidated Net Income of SRH during such period.
 
  (b) Notwithstanding paragraph (a) above, SRH and its Restricted Subsidiaries
may take the following actions so long as (in the case of clauses (2), (3),
(4), (5) and (7) below) no Default or Event of Default shall have occurred and
be continuing:
 
    (1) the payment of any dividend on Capital Stock of SRH or any Restricted
  Subsidiary within 60 days after the date of declaration thereof, if at such
  declaration date such declaration complied with the provisions of paragraph
  (a) above;
 
                                      74
<PAGE>
 
    (2) the repurchase, redemption or other acquisition or retirement of any
  shares of any class of Capital Stock of SRH or any Restricted Subsidiary,
  in exchange for, or out of the aggregate Net Proceeds from, a substantially
  concurrent issue and sale (other than to a Restricted Subsidiary) of shares
  of Qualified Capital Stock of SRH or the Issuer;
 
    (3) the repurchase, redemption, repayment, defeasance or other
  acquisition or retirement for value of any Subordinated Indebtedness in
  exchange for, or out of the aggregate Net Proceeds from, a substantially
  concurrent issue and sale (other than to a Restricted Subsidiary) of (i)
  Subordinated Indebtedness (provided such Indebtedness is on terms no less
  favorable to the Holders of the Notes than the terms of the Subordinated
  Indebtedness being redeemed) or (ii) shares of Qualified Capital Stock of
  SRH or the Issuer;
 
    (4) the repurchase, redemption or other acquisition of any Capital Stock
  of any Affiliate organized as a limited partnership in which SRH or the
  Issuer is a general partner pursuant to a redemption which is mandatory
  under the terms of such partnership's limited partnership agreement;
 
    (5) the repurchase or other acquisition of any Capital Stock of any
  Restricted Subsidiary, whether in one or a series of substantially
  contemporaneous transactions, which causes such Person to become a wholly-
  owned Restricted Subsidiary of SRH;
 
    (6) the payment on behalf of any Subsidiary or Affiliate of its allocated
  pro rata costs associated with the issuance of the Notes and any Investment
  in Capital Stock of such Person taken by SRH in payment thereof;
 
    (7) the distribution or dividend by SRH to its stockholders of the shares
  of Capital Stock of Red Oak owned by SRH, provided at the time of such
  distribution or dividend (and after giving effect thereto):
 
      (i) the Consolidated Fixed Charge Coverage Ratio for SRH's Reference
    Period for which internal financial statements are available
    immediately preceding the date of such distribution would have been at
    least 3.0 to 1.0; and
 
      (ii) SRH's Adjusted Consolidated Net Tangible Assets are equal to or
    greater than 200% of the consolidated Indebtedness of SRH and its
    Restricted Subsidiaries.
 
  The actions described in clause (1) of this paragraph (b) shall be
Restricted Payments that shall be permitted to be made in accordance with this
paragraph (b) but shall reduce the amount that would otherwise be available
for Restricted Payments under clause (3) of paragraph (a), provided that any
dividend paid pursuant to clause (1) of this paragraph (b) shall reduce the
amount that would otherwise be available under clause (3) of paragraph (a)
when declared, but not also when subsequently paid pursuant to clause (1) of
this paragraph (b), and provided that any Net Proceeds received under clauses
(2) or (3)(ii) of paragraph (b) shall not be included in subclauses (B) or (C)
of clause (3) of paragraph (a) above.
 
 Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries
 
  The Indenture provides that SRH may not, and may not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, or permit or
suffer to exist or become effective any consensual encumbrance or restriction
on the ability of any Restricted Subsidiary of SRH to (a) pay dividends or
make other distributions on its Capital Stock to SRH or any of its other
Restricted Subsidiaries, (b) make loans or advances or pay any Indebtedness or
other obligations owed to SRH or to any other Restricted Subsidiary, or (c)
transfer any of its properties or assets to SRH or to any other Restricted
Subsidiary, except encumbrances and restrictions existing under (i) this
Indenture, any Permitted Bank Credit Facility as in effect on the Issue Date
and any amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancings thereof, provided that
such amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancings are no more restrictive
with respect to such dividend and other payment or transfer restrictions than
those contained in the Permitted Bank Credit Facility as in effect on the
Issue Date and (ii) any agreement of a Person acquired by SRH or a Restricted
Subsidiary of SRH, which restrictions existed at the time of acquisition, were
not put in place in anticipation of such acquisition, and are not applicable
to any Person or property, other than the Person or any property of the Person
so acquired.

<PAGE>
 
 Limitation on Transactions with Affiliates
 
  The Indenture provides that SRH may not, and may not permit any of its
Subsidiaries to, enter directly or indirectly into, or permit to exist, any
transaction or series of related transactions with or for the benefit of any
Affiliate except for transactions made in good faith, the terms of which are
fair and reasonable to SRH or such Subsidiary, as the case may be, and are at
least as favorable as the terms which could be obtained by SRH or such
Subsidiary, as the case may be, in a comparable transaction made on an arm's
length basis with Persons who are not Affiliates and SRH delivers: (i) with
respect to any transaction or series of transactions with an Affiliate
involving aggregate consideration in excess of $1 million, an officers'
certificate certifying that such transaction or transactions comply with this
covenant, (ii) with respect to any transaction or series of transactions with
an Affiliate involving aggregate consideration in excess of $2 million, a
resolution of the Board of Directors set forth in an officers' certificate
certifying that such transaction or transactions comply with this covenant and
that such transaction or transactions have been approved in good faith by a
majority of the members of the Board of Directors who are independent (which
resolution shall be conclusive evidence of compliance with this provision),
provided that if there is not a majority of independent directors able to
approve such transaction, SRH shall also deliver an opinion as to the fairness
to SRH or such Subsidiary of such transaction or transactions from a financial
point of view issued by an investment banking firm of recognized national
standing, which opinion shall be conclusive evidence of compliance with this
provision; and (iii) with respect to any transaction or series of transactions
with an Affiliate involving aggregate consideration in excess of $5 million,
an officers' certificate as described in subclause (ii) above and an opinion
as to the fairness to SRH or such Subsidiary of such transaction or
transactions from a financial point of view issued by an investment banking
firm of recognized national standing, which resolution and opinion shall be
conclusive evidence of compliance with this provision; provided, however, that
this covenant will not restrict: (1) transactions between SRH and any of its
Restricted Subsidiaries or transactions between Restricted Subsidiaries of
SRH, (2) transactions pursuant to the Tax Sharing Agreement and the Security
Documents, (3) Restricted Payments permitted by the provisions of the
Indenture described under the covenant captioned "--Limitation on Restricted
Payments," (4) any employee compensation arrangements by SRH or any of its
Subsidiaries which has been approved by a majority of SRH's disinterested
directors and found in good faith by such directors to be in the best
interests of SRH or such Subsidiary, as the case may be; and (5) customary
directors' fees and indemnification and similar arrangements.
 
 Limitation on Asset Sales
 
  The Indenture provides that SRH may not, and may not permit any Restricted
Subsidiary to, consummate an Asset Sale unless: (a) SRH or such Restricted
Subsidiary, as the case may be, receives consideration at the time of such
Asset Sale at least equal to the fair market value (as determined in good
faith by resolution of the Board of Directors set forth in an officers'
certificate delivered to the Trustee, which determination shall be conclusive
evidence of compliance with this provision) of the assets or Capital Stock
being sold or issued or otherwise disposed of; and (b) at least 75% of the
value of the consideration for such Asset Sales consists of cash, Cash
Equivalents or Exchange Assets or any combination thereof; provided that the
amount of any liabilities (as shown on SRH's or such Restricted Subsidiary's
most recent balance sheet) of SRH or any Restricted Subsidiary (other than
contingent liabilities and liabilities that are Subordinated Indebtedness or
otherwise by their terms subordinated to the Notes, the Parent Guarantee or
the Subsidiary Guarantees) that are assumed by the transferee of such assets
pursuant to a customary novation agreement that releases SRH and such
Restricted Subsidiary from further liability shall also be deemed to be cash
for purposes of this provision.
 
  Within 365 days after the receipt of any Net Cash Proceeds from an Asset
Sale, SRH or such Restricted Subsidiary may apply such Net Cash Proceeds, at
its option, in any order or combination: (a) to repay and permanently reduce
Indebtedness outstanding under any Permitted Bank Credit Facility to which it,
the Issuer or any other Restricted Subsidiary of SRH is a party, (b) to make
Capital Expenditures or (c) to make other acquisitions of assets to be used in
SRH's and its Restricted Subsidiaries' oil and gas business. Pending the final
application of any such Net Cash Proceeds, SRH or such Restricted Subsidiary
may temporarily invest such Net Cash Proceeds in any manner that is not
prohibited by the terms of the Indenture. Any Net Cash Proceeds from Asset
Sales that are not applied as provided in clauses (a) through (c) of the first
sentence of this paragraph will (after expiration of the relevant periods) be
deemed to constitute "Excess Cash."
 
                                      76
<PAGE>
 
  When the amount of Excess Cash exceeds $10 million, the Issuer or SRH will
make an irrevocable, unconditional offer (an "Excess Cash Offer") to the
Holders to purchase the maximum amount of Notes which could be acquired by
application of such amount of Excess Cash as described herein (the "Excess
Cash Offer Amount"), in cash at the purchase price equal to 100% of the
principal amount thereof (the "Excess Cash Offer Price"), together with
accrued and unpaid interest to the Excess Cash Purchase Date.
 
  Notice of an Excess Cash Offer will be sent at least 30 and not more than 60
days prior to the Excess Cash Purchase Date, by first-class mail, by the
Issuer or SRH to each Holder at the address on the Note Register, with a copy
to the Trustee. Such notice will set forth a date on which the Notes tendered
shall be accepted (the "Excess Cash Purchase Date") and the Excess Cash Offer
shall remain open for at least 20 Business Days and close no later than 30
Business Days after the date such notice is given. The notice to the Holders
will contain all information, instructions and materials required by
applicable law or otherwise material to such Holders' decision to tender Notes
pursuant to the Excess Cash Offer.
 
  To the extent applicable and if required by law, the Issuer and SRH will
comply with Section 14 of the Exchange Act, the provisions of Regulation 14E
and any other tender offer rules under the Exchange Act and other securities
laws, rules, and regulations which may then be applicable to any Excess Cash
Offer by the Issuer or SRH; and, if such laws, rules, and regulations require
or prohibit any action inconsistent with the foregoing, compliance by the
Issuer or SRH with such laws, rules, and regulations will not constitute a
breach of its obligations with respect to the foregoing.
 
  On or before an Excess Cash Purchase Date, the Issuer or SRH shall (i)
accept for payment Notes or portions thereof properly tendered pursuant to the
Excess Cash Offer, (ii) deposit with the Paying Agent money sufficient to pay
the Excess Cash Offer Price, plus accrued and unpaid interest thereon to the
Excess Cash Purchase Date of all Notes or portions thereof so accepted, and
(iii) deliver to the Trustee all Notes so accepted together with an officers'
certificate listing the Notes or portions thereof being purchased by the
Issuer or SRH. The Paying Agent shall promptly mail to Holders of Notes so
accepted payment in an amount equal to the Excess Cash Offer Price, plus
accrued and unpaid interest thereon to the Excess Cash Purchase Date. The
Trustee shall promptly cancel all Notes accepted by the Issuer pursuant to the
Excess Cash Offer and authenticate and mail to the Holders of Notes so
accepted a new Note equal to the principal amount of any unpurchased portion
of the Note surrendered. Any Notes not so accepted shall be promptly mailed by
the Issuer to the Holder thereof. The Issuer or SRH will publicly announce the
results of the Excess Cash Offer on or as soon as practicable after the Excess
Cash Purchase Date.
 
  If the amount required to acquire all Notes tendered by Holders pursuant to
the Excess Cash Offer (the "Excess Cash Acceptance Amount") shall be less than
the aggregate Excess Cash Offer Amount, then the excess of the Excess Cash
Offer Amount over the Excess Cash Acceptance Amount may be used by SRH or any
Restricted Subsidiary in any manner permitted by the Indenture. Upon
consummation of any Excess Cash Offer made in accordance with the terms of the
Indenture, the amount of Excess Cash will be reduced to zero.
 
 Limitation on Liens
 
  The Indenture provides that SRH may not, and may not permit any Restricted
Subsidiary to, directly or indirectly, incur, or suffer to exist any Lien upon
any of their respective properties or assets, whether now owned or hereafter
acquired, other than Permitted Liens.
 
 Limitation on Lines of Business
 
  The Indenture provides that SRH will not engage in any line of business
other than to act as a holding company for the Issuer, Sierra and Red Oak and
such other business activities as are reasonably related or incidental
thereto. The Indenture will provide that the Restricted Subsidiaries will not
engage in any line of business other than the oil and gas exploration and
production business, such other business activities as are reasonably related
or incidental thereto and any other business activities of SRH and its
Restricted Subsidiaries conducted as of the Issue Date.
 
                                      77

 Designation of Unrestricted Subsidiaries
 
  The Board of Directors of SRH may designate any Restricted Subsidiary (other
than the Issuer) to be an Unrestricted Subsidiary if such designation would
not cause a Default or an Event of Default and following such designation, SRH
could Incur $1.00 of additional Indebtedness pursuant to paragraph (i) of the
covenant described herein under the caption "Limitation on Incurrences of
Additional Indebtedness and Issuances of Disqualified Capital Stock." For
purposes of making such determination, all outstanding Investments by SRH and
its Restricted Subsidiaries in the Subsidiary so designated which have not
been repaid in cash will be deemed to be Restricted Payments at the time of
such designation and will reduce the amount available for Restricted Payments
under clause (3) of paragraph (a) of the covenant "Limitation on Restricted
Payments." All such outstanding Investments will be deemed to constitute
Restricted Investments in an amount equal to the greater of the fair market
value or book value of such Investments at the time of such designation. Such
designation will only be permitted if such Restricted Payment would be
permitted at such time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. In addition, the definition of
"Unrestricted Subsidiary" set forth under the caption "Certain Definitions"
describes the circumstances under which a future Unrestricted Subsidiary of
SRH may be designated as a Restricted Subsidiary by the Board of Directors of
SRH.
 
  The Board of Directors of SRH or any Restricted Subsidiary may designate any
Unrestricted Subsidiary of such Person (other than Red Oak) as a Restricted
Subsidiary of such Person; provided that, (a) if the Unrestricted Subsidiary
has any Indebtedness outstanding or is otherwise liable for any Indebtedness
or has a negative Net Worth, then immediately after giving pro forma effect to
such designation, such Person could Incur at least $1.00 of additional
Indebtedness (other than Permitted Indebtedness) pursuant to the provisions
described under the heading "--Covenants--Limitation on Incurrences of
Additional Indebtedness and Issuances of Disqualified Capital Stock"
(assuming, for purposes of this calculation, that each dollar of negative Net
Worth is equal to one dollar of Indebtedness), (b) all Indebtedness of such
Unrestricted Subsidiary shall be deemed to be Incurred by a Restricted
Subsidiary of the Person on the date such Unrestricted Subsidiary becomes a
Restricted Subsidiary, and (c) no Default or Event of Default would occur or
be continuing after giving effect to such designation. Any Subsidiary of an
Unrestricted Subsidiary shall be an Unrestricted Subsidiary for purposes of
the Indenture.
 
 Limitation on the Sale or Issuance of Capital Stock of Restricted
Subsidiaries
 
  The Indenture provides that SRH will not sell or otherwise dispose of any
shares of Capital Stock of any Restricted Subsidiary (other than the Issuer),
and shall not permit any Restricted Subsidiary (other than the Issuer),
directly or indirectly, to issue or sell or otherwise dispose of any of its
Capital Stock except (a) to SRH or a wholly-owned Restricted Subsidiary, or
(b) if all shares of Capital Stock of such Restricted Subsidiary are sold or
otherwise disposed of. In connection with any sale or disposition of Capital
Stock of any Restricted Subsidiary, SRH will be required to comply with the
covenant described under the caption "Limitation on Asset Sales," and in the
case of a sale of the Issuer, the covenants described under the captions
"Repurchase of Notes at the Option of the Holder Upon a Change of Control" and
"Limitation on Merger, Sale or Consolidation."
 
 Ownership of Restricted Subsidiaries
 
  The Indenture provides that all of the Capital Stock of each Restricted
Subsidiary (other than the Issuer, TPI and Southwest Software) be owned,
whether directly or indirectly, by SRH. The Indenture will also provide that
SRH will ensure that the Issuer remain a Restricted Subsidiary so long as any
of the Notes remains outstanding.
 
 Limitation on Merger, Sale or Consolidation
 
  The Indenture provides that SRH will not consolidate with or merge with or
into any other Person or, directly or indirectly, sell, lease, assign,
transfer, or convey all or substantially all of its assets (computed on a
consolidated basis), to another Person or group of Persons acting in concert,
whether in a single transaction or
 
                                      78
<PAGE>
 
through a series of related transactions, unless (i) either (a) SRH is the
continuing Person or (b) the resulting, surviving, or transferee entity is a
corporation organized under the laws of the United States, any state thereof,
or the District of Columbia, and shall expressly assume all of the obligations
of SRH under the Indenture, the Parent Guarantee and the Security Documents by
appropriate documents supplemental thereto, executed and delivered to the
Trustee on or prior to the consummation of such transaction, in form
satisfactory to the Trustee; (ii) no Default or Event of Default shall exist
or shall occur immediately after giving effect to such transaction; (iii)
immediately after giving effect to such transaction on a pro forma basis, the
Net Worth of the resulting surviving or transferee entity is at least equal to
the Net Worth of SRH immediately prior to such transaction; and (iv) except
for a merger of SRH with or into any wholly-owned Restricted Subsidiary, the
resulting surviving or transferee entity would immediately thereafter be
permitted to Incur at least $1.00 of additional Indebtedness (other than
Permitted Indebtedness) pursuant to paragraph (i) of the covenant described
herein under the caption "Limitation on Incurrences of Additional Indebtedness
and Issuances of Disqualified Capital Stock." For purposes of this covenant,
the Consolidated Fixed Charge Coverage Ratio shall be determined on a pro
forma consolidated basis (giving effect to the transaction) for the Reference
Period immediately preceding such transaction.
 
  The Indenture provides that the Issuer will not consolidate with or merge
with or into any other Person, or, directly or indirectly, sell, lease,
assign, transfer, or convey all or substantially all of its assets (computed
on a consolidated basis), to another Person or group of Persons acting in
concert, whether in a single transaction or through a series of related
transactions, unless (i) either (a) the Issuer is the continuing Person or (b)
the resulting, surviving, or transferee entity is a corporation organized
under the laws of the United States, any state thereof, or the District of
Columbia, and shall expressly assume all of the obligations of the Issuer
under the Indenture and the Notes by a supplemental indenture, executed and
delivered to the Trustee on or prior to the consummation of such transaction,
in form satisfactory to the Trustee; (ii) no Default or Event of Default shall
exist or shall occur immediately after giving effect to such transaction;
(iii) immediately after giving effect to such transaction on a pro forma
basis, the Net Worth of the surviving or transferee entity is at least equal
to the Net Worth of the Issuer immediately prior to such transaction; (iv)
except for a merger of the Issuer with or into SRH or any wholly-owned
Restricted Subsidiary, the resulting surviving or transferee entity would
immediately thereafter be permitted to Incur at least $1.00 of additional
Indebtedness (other than Permitted Indebtedness) pursuant to paragraph (i) of
the covenant described herein under the caption "Limitation on Incurrences of
Additional Indebtedness and Issuances of Disqualified Capital Stock"; (v) SRH
shall have executed and delivered to the Trustee, in form satisfactory to the
Trustee, a supplemental indenture confirming the obligation of SRH to pay the
principal of and interest on the Notes pursuant to the Parent Guarantee and to
perform all the covenants of SRH under the Indenture and the Parent Guarantee;
(vi) each Subsidiary Guarantor shall have executed and delivered to the
Trustee, in form satisfactory to the Trustee, a supplemental indenture
confirming such Subsidiary Guarantor's obligations to pay the principal of and
interest on the Notes pursuant to its Subsidiary Guarantee; and (vii) the
Trustee shall have received an opinion of counsel to the effect that such
consolidation, merger, conveyance, transfer or lease will not result in the
Issuer being required to make any deduction for or on account of taxes from
payments made under or in respect of the Notes. For purposes of this covenant,
the Consolidated Fixed Charge Coverage Ratio shall be determined on a pro
forma consolidated basis (giving effect to the transaction) for the Reference
Period immediately preceding such transaction.
 
 
  Upon any consolidation or merger or any transfer of all or substantially all
of the assets of SRH or the Issuer in accordance with the foregoing, the
successor Person formed by such consolidation or merger or the Person to whom
such transfer is made, shall succeed to, and be substituted for, and may
exercise every right and power of, SRH under the Parent Guarantee and the
Security Documents or the Issuer under the Indenture, as the case may be, with
the same effect as if such successor corporation had been named as SRH or the
Issuer therein.
 
  This covenant includes a phrase relating to the sale, lease, transfer,
conveyance or other dispositions of "all or substantially all" of the assets
of a Person. Although there is a developing body of judicial opinions
interpreting the phrase "all or substantially all," no precise standard exists
under applicable law. Accordingly, the ability of the Holders of the Notes to
declare an Event of Default as the result of such a disposition or series of
dispositions is uncertain.
 
                                      79
<PAGE>
 
EVENTS OF DEFAULT AND REMEDIES
 
  The Indenture defines an Event of Default as (i) the failure by the Issuer
to pay installments of interest on the Notes as and when the same become due
and payable and the continuance of any such failure for 30 days, (ii) the
failure by the Issuer to pay all or any part of the principal or premium, if
any, on the Notes when and as the same become due and payable at maturity,
redemption, by acceleration or otherwise, (iii) the failure by the Issuer or
SRH to comply with the provisions under the caption "Repurchase of Notes at
the Option of the Holder Upon a Change of Control," "Limitation on Asset
Sales" or "Limitation on Merger, Sale or Consolidation," (iv) the failure by
SRH, the Issuer or any of its other Restricted Subsidiaries to observe or
perform any other covenant, agreement or warranty contained in the Notes, the
Indenture, the Parent Guarantee, any Subsidiary Guarantee or any Security
Document and, subject to certain exceptions, the continuance of such failure
for a period of 30 days after written notice is given to the Issuer by the
Trustee or to the Issuer and the Trustee by the Holders of at least 25% of the
principal amount of the Notes then outstanding, (v) certain events of
bankruptcy, insolvency, or reorganization in respect of SRH, the Issuer or any
of its other Significant Subsidiaries, (vi) a default which extends beyond any
stated period of grace applicable thereto (including any extension thereof)
under any mortgage, indenture, or instrument under which there is outstanding
any Indebtedness of SRH, the Issuer or any of its other Restricted
Subsidiaries aggregating in excess of $1 million or a failure to pay such
Indebtedness at its stated maturity, provided that a waiver by all of the
lenders of such Indebtedness of such default shall constitute a waiver
hereunder for the same period, (vii) one or more final judgments not covered
by insurance aggregating at least $1 million at any one time rendered against
SRH, the Issuer or any of its other Restricted Subsidiaries and not stayed or
discharged within 60 days, (viii) any Note, the Indenture or any Security
Document not being in full force and effect (except where no material adverse
effect to the Holders of the Notes would result) or ceasing to give the
Trustee a perfected Lien on the Collateral, or (ix) the Parent Guarantee or
any of the Subsidiary Guarantees ceases to be in full force and effect or the
Parent Guarantee or any of the Subsidiary Guarantees is declared to be null
and void or unenforceable or the Parent Guarantee or any of the Subsidiary
Guarantees is found to be invalid or any Guarantor denies its liability under
the Parent Guarantee or its Subsidiary Guarantee (other than by reason of
release of a Subsidiary Guarantor in accordance with the terms of the
Indenture).
 
  The Indenture provides that if an Event of Default occurs and is continuing
and if it is known to the Trustee, the Trustee must, within 90 days after the
occurrence of such Event of Default, give to the Holders notice of such
default; provided, that, except in the case of default in payment of principal
of, premium, if any, or interest on the Notes, the Trustee will be protected
in withholding such notice if it in good faith determines that the withholding
of such notice is in the interest of the Holders of the Notes.
 
  If an Event of Default occurs and is continuing (other than an Event of
Default specified in clause (v) above), then in every such case, unless the
principal of all of the Notes shall have already become due and payable,
either the Trustee or the Holders of 25% of the principal amount of Notes then
outstanding, by notice in writing to the Issuer (and to the Trustee if given
by Holders), may declare all principal of, premium, if any, and accrued
interest on the Notes to be due and payable immediately. If an Event of
Default specified in clause (v) above occurs, all principal, premium, if any,
and accrued interest on the Notes will be immediately due and payable on all
outstanding Notes without any declaration or other act on the part of the
Trustee or the Holders. The Holders of not less than a majority of the
principal amount of Notes are authorized to rescind such acceleration if any
existing Events of Default, other than the non-payment of the principal of,
premium, if any, and interest on the Notes which have become due solely by
such acceleration, have been cured or waived.
 
  Prior to the declaration of acceleration of the Notes, the Holders of a
majority of the Notes at the time outstanding may waive on behalf of all the
Holders any Default or Event of Default, except a Default in the payment of
principal of, premium, if any, or interest on any Note not yet cured, or a
Default, or Event of Default with respect to any covenant or provision which
cannot be modified or amended without the consent of all of the Holders of the
Notes. Subject to the provisions of the Indenture relating to the duties of
the Trustee, the Trustee will be under no obligation to exercise any of its
rights or powers under the Indenture at the request, order or direction of any
of the Holders, unless such Holders have offered to the Trustee reasonable
security or indemnity.
 
                                      80
<PAGE>
 
Subject to all provisions of the Indenture, the Holders of a majority of the
Notes at the time outstanding will have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.
 
COLLATERAL
 
  The Parent Guarantee is secured by the pledge to the Trustee for the ratable
benefit of the Holders of (x) all of the Capital Stock of Sierra now or
hereafter directly owned by SRH, equals approximately 30% of the outstanding
shares of Capital Stock of Sierra, and (y) all of the Capital Stock of Red Oak
now or hereafter directly owned by SRH, which equals approximately 82% of the
outstanding shares of Capital Stock of Red Oak.
 
  In the event of an Equity Offering in which SRH sells its shares of Sierra
or Red Oak, such shares may be released by the Trustee from the Lien of the
Security Documents for sale in connection with such Equity Offering. The
Trustee would have no Lien on the proceeds from any such sale of released
shares. Notwithstanding the foregoing, no such shares may be released by the
Trustee if at the time of such proposed release, a Default or Event of Default
has occurred and is continuing or would occur as a result of such release. In
addition, the Trustee will release the shares of Red Oak from the Lien of the
Security Documents to the extent such shares are subject to a transaction
permitted by clause (7) of paragraph (b) of the covenant. See "--Limitation on
Restricted Payments."
 
FORECLOSURE ON COLLATERAL
 
  If the Notes become due and payable prior to the Stated Maturity Date
thereof or are not paid in full at the Stated Maturity Date thereof, the
Trustee may take all actions it deems necessary or appropriate, including, but
not limited to, foreclosing upon the Collateral in accordance with the
Security Documents and applicable law. The proceeds received from the sale of
any Collateral that is the subject of a foreclosure or collection suit shall
be applied first to pay the expenses of such foreclosure or suit and amounts
then payable to the Trustee and thereafter to pay the principal of and
interest on the Notes. The Trustee has the power to institute and maintain
such suits and proceedings as it may deem expedient to prevent impairment of,
or to preserve or protect its and the Holders' interest in, the Collateral.
 
  There can be no assurance that the Trustee will be able to sell the
Collateral without substantial delays or that the proceeds obtained will be
sufficient to pay all amounts owing to Holders of the Notes. See "Risk
Factors--Adequacy of Collateral; Risks of Foreclosure" and "--Possible
Limitations on Enforceability of Subsidiary Guarantees."
 
LEGAL DEFEASANCE; SATISFACTION AND DISCHARGE OF THE INDENTURE
 
  The Issuer will be deemed to have paid and discharged the entire
indebtedness on all of the outstanding Notes (except as to (i) Issuer's right
of optional redemption, (ii) rights of Holders to receive payments of
principal of, premium, if any, and interest on the Notes (but not the Change
of Control Purchase Price or the Excess Cash Offer Price) and any other rights
of the Holders with respect to such amounts, (iii) the rights, obligations and
immunities of the Trustee under the Indenture, and (iv) certain other
specified provisions in the Indenture (the foregoing exceptions (i) through
(iv) are collectively referred to as the "Reserved Rights")) on the 91st day
(or one day after such other greater period of time in which any such deposit
of trust funds may remain subject to set aside or avoidance under applicable
bankruptcy or insolvency laws, e.g., one year after any such deposit) after
the irrevocable deposit by the Issuer with the Trustee, in trust for the
benefit of the Holders, of (i) money in an amount, (ii) U.S. Government
Obligations which through the payment of interest and principal will provide,
not later than one day before the due date of payment in respect of the Notes,
money in an amount, or (iii) a combination thereof, sufficient to pay and
discharge the principal of, premium, if any, and interest on the Notes then
outstanding on the Stated Maturity Date or on the applicable redemption date,
as the case may be, and the Issuer must specify whether the Notes are being
defeased to the Stated Maturity Date or to a particular redemption date. Such
a trust may be established only if certain conditions are satisfied, including
delivery by the Issuer to the Trustee of an opinion of outside counsel
acceptable to the Trustee (who may be outside counsel to the Issuer) to the
effect that (i) the defeasance and discharge will not be deemed, or result in,
a taxable event
 
                                      81
<PAGE>
 
for Federal income tax purposes, with respect to the Holders, (ii) the
Issuer's deposit will not result in the Issuer or any Guarantor, the trust or
the Trustee being subject to regulation under the Investment Company Act of
1940, and (iii) after the passage of 90 days (or any greater period of time in
which any such deposit of trust funds may remain subject to bankruptcy or
insolvency laws insofar as those laws apply to the Issuer or any Guarantor)
following the deposit of the trust funds, such funds will not be subject to
set aside or avoidance under any bankruptcy, insolvency, or other similar laws
affecting creditors' rights generally. The Indenture will not be discharged
if, among other things, an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization of the Issuer or any Guarantor shall
have occurred and be continuing on the date of such deposit. The Indenture,
the Parent Guarantee, any Subsidiary Guarantee and each of the Security
Documents will cease to be of further effect as to all outstanding Notes when
(i) all outstanding Notes have been delivered to the Trustee for cancellation
or (ii) the Issuer has paid or caused to be paid the principal of, premium, if
any, and interest on the Notes.
 
RULE 144A INFORMATION REQUIREMENT
 
  The Issuer and SRH have agreed to furnish to the Holders or beneficial
Holders of the Old Notes and prospective purchasers of the Old Notes
designated by the Holders of the Old Notes, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Exchange Act until such time as the Issuer either exchanges all of the Old
Notes for the Exchange Notes or has registered all of the Old Notes for resale
under the Exchange Act.
 
REPORTS
 
  The Indenture requires SRH to furnish to the Trustee, within 60 days after
the end of each fiscal quarter or 90 days after the end of a fiscal quarter
that is also the end of a fiscal year, an officers' certificate to the effect
that responsible officers of SRH have conducted or supervised a review of the
activities of SRH and its Subsidiaries and of performance under the Indenture
and that, to the best of such officers' knowledge, based on their review, SRH
and the Issuer have fulfilled all of their obligations under the Indenture or,
if there has been a Default, specifying each Default known to them, its nature
and its status. SRH and the Issuer will also be required to notify the Trustee
of any changes in the composition of the Board of Directors of SRH or any of
its Subsidiaries or of any amendment to the charter or bylaws of SRH or any of
its Subsidiaries.
 
  Each of SRH and its Subsidiaries, where applicable, shall deliver to the
Trustee and to each Holder, within 15 days after it files them with the SEC,
copies of all reports and information that it is required to file with the SEC
pursuant to Section 13 or 15(d) of the Exchange Act. In addition, whether or
not required by the rules and regulations of the SEC, SRH will file a copy of
all such information with the SEC for public availability (unless the SEC will
not accept such a filing) and make such information available to investors or
prospective investors who request it in writing.
 
  Concurrently with the reports delivered pursuant to the preceding paragraph,
SRH will be required to deliver to the Trustee and to each Holder annual and
quarterly financial statements with appropriate footnotes of SRH and its
consolidated Subsidiaries, all prepared and presented in a manner
substantially consistent with those of SRH required by the preceding
paragraph.
 
  The Issuer is required upon becoming aware of any Default or Event of
Default to deliver to the Trustee a statement specifying such Default or Event
of Default.
 
AMENDMENTS AND SUPPLEMENTS
 
  The Indenture contains provisions permitting the Issuer, SRH and the Trustee
to enter into a supplemental indenture or amend the Security Documents for
certain limited purposes without the consent of the Holders, including curing
ambiguities, defects or inconsistencies, releasing Subsidiary Guarantees as
described under "--Ranking and Guarantees" or making any other change with

CONCERNING THE TRUSTEE

should it become a creditor of the Issuer or any Guarantor, to obtain payment
of claims in certain cases, or to realize on certain property received in

conflicting interests, it must eliminate such conflict within 90 days, apply
to the SEC for permission to continue or resign.
 
  The Holders of a majority of the principal amount of the then outstanding
Notes will have the right to direct the time, method and place of conducting
any proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the
Indenture at the request of any Holder of the Notes.
 
NO PERSONAL LIABILITY OF STOCKHOLDERS, OFFICERS OR DIRECTORS
 
  No stockholder, officer, or director, as such, past, present, or future of

Subsidiary Guarantees or any Security Document by reason of his or its status
as such stockholder, officer, or director.

provided.
 
  "Adjusted Consolidated Net Income" of SRH for any period means the Net
Income (loss) of SRH and its Restricted Subsidiaries for such period,
determined in accordance with GAAP, excluding (without duplication) the Net
Income of Red Oak or any other Unrestricted Subsidiary which is a consolidated

Income of SRH attributable to the minority interest in Red Oak or any other
Unrestricted Subsidiary which is a consolidated Subsidiary for such period.
 
  "Adjusted Consolidated Net Tangible Assets" means (without duplication), as
of the date of determination, (a) the sum of (i) discounted future net revenue
from proved oil and gas reserves of SRH and its Restricted Subsidiaries
calculated in accordance with SEC guidelines before any state or federal
income taxes, as estimated or audited by independent petroleum engineers in
one or more Reserve Reports prepared as of the end of SRH's most recently
completed fiscal year as increased by, as of the date of determination, the
discounted future net revenue of (A) estimated proved oil and gas reserves of
SRH and its Restricted Subsidiaries attributable to any acquisition
consummated since the effective date of such year-end Reserve Reports and (B)
estimated oil and gas reserves of SRH and its Restricted Subsidiaries
attributable to extensions, discoveries and other additions and upward
revisions of estimates of proved oil and gas reserves due to exploration,
development or exploitation, production or other activities conducted or
otherwise occurring since the effective date of such year-end Reserve Reports
which, in the case of sub-clauses (A) and (B), would, in accordance with
standard industry practice, result in such increases, in each case calculated
in accordance with SEC guidelines (utilizing the prices and costs utilized in
such year-end Reserve Reports), and decreased by, as of the date of
determination, the discounted future net revenue of (C) estimated proved oil
and gas reserves of SRH and its Restricted Subsidiaries produced or disposed
of since the effective date of such year-end Reserve Reports and (D)
reductions in the estimated oil and gas reserves of SRH and its Restricted
Subsidiaries since the effective date of such year-end Reserve Reports
attributable to downward revisions of estimates of proved oil and gas reserves

activities conducted or otherwise occurring since the effective date of such
year-end Reserve Reports which would, in accordance with standard industry
practice, result in such revisions, in each case calculated in accordance with
SEC guidelines (utilizing the prices utilized in such year-end Reserve
Reports); provided that, in the case of each of the determinations made
pursuant to sub-clauses (A) through (D) above, such increases and decreases
shall be as estimated by SRH's engineers, except that if there is a Material
Change and in connection with the Incurrence of Indebtedness for which the
Consolidated Fixed Charge Coverage Ratio must be determined, all or any part
of an increase in discounted future net revenue resulting from the matters
described in sub-clauses (A) and (B) above is needed to permit the Incurrence
of such Indebtedness, then the discounted future net revenue utilized for
purposes of this clause (a) (i) shall be confirmed in writing by independent
petroleum engineers, provided further that, if the events referred to in sub-
clauses (C) and (D) above, when taken alone, would not cause a Material
Change, then such written confirmation need only cover the incremental
additions to discounted future net revenue resulting from the determinations
made pursuant to sub-clauses (A) and (B) above to the extent needed to permit
the Incurrence of such Indebtedness, (ii) the capitalized costs that are
attributable to oil and gas properties of SRH and its Restricted Subsidiaries
to which no proved oil and gas reserves are attributed, based on SRH's books
and records as of a date no earlier than the date of SRH's latest annual or

audited financial statements, minus (b) the sum of (i) minority interests,
(ii) any non-current portion of gas balancing liabilities of SRH and its
Restricted Subsidiaries reflected in SRH's latest annual or quarterly
financial statements, (iii) the discounted future net revenue, calculated in
accordance with SEC guidelines (utilizing the prices utilized in SRH's year-
end
 
                                      84

Reserve Reports), attributable to reserves which are required to be delivered
to third parties to fully satisfy the obligations of SRH and its Restricted
Subsidiaries with respect to Production Payments on the schedules specified
with respect thereto, (iv) the discounted future net revenue, calculated in
accordance with SEC guidelines (utilizing the same prices utilized in SRH's
initial or year-end Reserve Reports), attributable to reserves subject to
participation interests, overriding royalty interests or other interests of
third parties, pursuant to participation, partnership, vendor financing or
other agreements then in effect, or which otherwise are required to be
delivered to third parties and (v) the amount of environmental liabilities
payable by SRH or any Restricted Subsidiary. If SRH changes its method of

BOOK ENTRY; DELIVERY AND FORM
 
  Except as described in the next paragraph, the Notes are represented by a
single, permanent global certificate in definitive, fully registered form (the
"Global Note"). The Global Note was deposited on October 14, with, or on
behalf of, The Depository Trust Company ("DTC") and registered in the name of
a nominee of DTC. The Global Note is subject to certain restrictions on
transfer set forth therein and bears the legend regarding such restrictions
set forth under "Notice to Investors."
 
                                      95
<PAGE>
 
  Notes (i) originally purchased by or transferred to "foreign purchasers" or
Accredited Investors who are not Qualified Institutional Buyers or (ii) held
by Qualified Institutional Buyers who elect to take physical delivery of their
certificates instead of holding their interest through the Global Note (and
which are thus ineligible to trade through DTC) (collectively referred to
herein as the "Non-Global Purchasers") will be issued in registered
certificated form ("Certificated Securities"). Upon the transfer to a
Qualified Institutional Buyer of any Certificated Security initially issued to
a Non-Global Purchaser, such Certificated Security will, unless the transferee
requests otherwise or the Global Note has previously been exchanged in whole
for Certificated Securities, be exchanged for an interest in the Global Note.
For a description of the restrictions on the transfer of Certificated
Securities and any interest in the Global Note, see "Notice to Investors."
 
  Pursuant to procedures established by DTC (i) upon the issuance of the
Global Note, DTC or its custodian credited, on its internal system, the
principal amount of Notes of the individual beneficial interests represented
by such Global Note to the respective accounts for persons who have accounts
with DTC and (ii) ownership of beneficial interests in the Global Note is
shown on, and the transfer of such ownership will be effected only through,
records maintained by DTC or its nominee (with respect to interests of
participants) and the records of participants (with respect to interests of
persons other than participants). Such accounts initially were designated by
or on behalf of the Initial Purchasers and ownership of beneficial interests
in the Global Note is limited to persons who have accounts with DTC
("participants") or persons who own interests through participants. Qualified
Institutional Buyers will hold their interests in the Global Note directly
through DTC, if they are participants in such system, or indirectly through
organizations which are participants in such system.
 
  So long as DTC or its nominee is the registered owner or holder of the
Notes, DTC or such nominee, as the case may be, will be considered the sole
owner or holder of the Notes represented by such Global Note for all purposes
under the Indenture. No beneficial owner of an interest in any Global Note
will be able to transfer that interest except in accordance with DTC's
procedures in additional to those provided for under the Indenture.
 
  Payments of the principal of, premium, if any, and interest (including
Additional Interest) on, the Global Note will be made to DTC or its nominee,
as the case may be, as the registered owner thereof. None of the Issuer, the
Trustee or any paying agent of the Issuer will have any responsibility or
liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests in the Global Note or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
  The Issuer expects that DTC or its nominee, upon receipt of any payment of
principal, premium, if any, or interest (including Additional Interest) in
respect of the Global Note, will credit participants' accounts with payments
in amounts proportionate to their respective beneficial interests in the
principal amount of the Global Note as shown on the records of DTC or its
nominee. The Issuer also expects that payments by participants to owners of
beneficial interests in the Global Note held through such participants will be
governed by standing instructions and customary practice, as is now the case
with securities held for the accounts of customers registered in the names of
nominees for such customers. Such payments will be the responsibility of such
participants.
 
  Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same day funds. If a
holder requires physical delivery of a Certified Security for any reason,
including to sell Notes to persons in states which require physical delivery
of the Certificated same day Securities, or to pledge such securities, such
holder must transfer its interest in the Global Note in accordance with the
normal procedures of DTC and with the procedures set forth in the Indenture.
 
  DTC has advised the Issuer that it will take any action permitted to be
taken by a holder of Notes (including the presentation of Notes for exchange
as described under "Exchange and Registration Rights Agreement") only at the
direction of one or more participants to whose account the interests in the
Global Note are credited and only in respect of such portion of the aggregate
principal amount of Notes as to which such participant or participants have
given such direction. However, if there is an Event of Default under the
Indenture, DTC will exchange the Global Note for Certificated Securities,
which it will distribute to its participants.
 
                                      96

  DTC has advised the Issuer as follows: DTC is a limited purpose trust
company organized under laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the Uniform
Commercial Code and a "clearing agency" registered pursuant to the provisions
of Section 17A of the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book entry changes in
accounts of its participants, thereby eliminating the need for physical
movement of certificates. Participants include securities brokers and dealers,
banks, trust companies and clearing corporations and certain other
organizations. Indirect access to the DTC system is available to others such
as banks, brokers, dealers and trust companies that clear through or maintain
a custodial relationship with a participant, either directly or indirectly.
 
  Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Note among participants of DTC, it is
under no obligation to perform such procedures, and such procedures may be
discontinued at any time. None of the Issuer, the Initial Purchasers or the
Trustee will have any responsibility for the performance by DTC or its
participants or indirect participants of their respective obligations under
the rules and procedures governing their operations.
 
  If DTC is at any time unwilling or unable to continue as a depositary for
the Global Note and a successor depositary is not appointed by the Issuer
within 90 days, or at SRH's election at any time, Certificated Securities will
be issued in exchange for the Global Note.

                  EXCHANGE AND REGISTRATION RIGHTS AGREEMENT
 
  Pursuant to the Registration Rights Agreement, SRH and the Issuer agreed to
file with the Commission the Exchange Offer Registration Statement on the
appropriate form under the Securities Act with respect to an offer to exchange
the Old Notes for the Exchange Notes. Upon the effectiveness of the Exchange
Offer Registration Statement, the Issuer will offer to the holders of Notes
who are able to make certain representations the opportunity to exchange their
Old Notes for Exchange Notes.
 
  If (i) SRH and the Issuer are not permitted to file the Exchange Offer
Registration Statement or to consummate the Exchange Offer because the
Exchange Offer is not permitted by applicable law or Commission policy or (ii)
any holder of Notes notifies the Issuer within the specified time period that
(A) due to a change in law or policy it is not entitled to participate in the
Exchange Offer, (B) due to a change in law or policy it may not resell the
Exchange Notes acquired by it in the Exchange Offer to the public without
delivering a prospectus and the prospectus contained in the Exchange Offer
Registration Statement is not appropriate or available for such resales by
holder or (C) it is a broker-dealer and owns Old Notes acquired directly from
the Issuer or an affiliate of SRH or the Issuer, SRH and the Issuer will file
with the Commission the Shelf Registration Statement to cover resales of the
Transfer Restricted Notes (as defined) by the holders thereof. SRH and the
Issuer will use their best efforts to cause the applicable registration
statement to be declared effective within specified periods by the Commission.
For purposes of the foregoing, "Transfer Restricted Notes" means each Old Note
until (i) the date on which such Old Note has been exchanged by a person other
than a broker-dealer for an Exchange Note in the Exchange Offer, (ii)
following the exchange by a broker-dealer in the Exchange Offer of an Old Note
for an Exchange Note, the date on which such Exchange Note is sold to a
purchaser who receives from such broker-dealer on or prior to the date of such
sale a copy of the prospectus contained in the Exchange Offer Registration
Statement, (iii) the date on which such Old Note has been effectively
registered under the Securities Act and disposed of in accordance with the
Shelf Registration Statement or (iv) the date on which such Old Note is
distributed to the public pursuant to Rule 144 under the Securities Act.
 
  Under existing Commission interpretations, the Transfer Restricted Notes
would, in general, be freely transferable after the Exchange Offer without
further registration under the Securities Act; provided, however, that in the
case of broker-dealers participating in the Exchange Offer, a prospectus
meeting the requirements of the Securities Act will be delivered upon resale
by such broker-dealer in connection with resales of the Exchange Notes. SRH
and the Issuer have agreed, for a period of 180 days after consummation of the
Exchange Offer, to make available a prospectus meeting the requirements of the
Securities Act to any such broker-dealer for use in connection with any resale
of any Exchange Notes acquired in the Exchange Offer. A broker-dealer which
delivers such a prospectus to purchasers in connection with such resales will
be subject to certain of the civil liability provisions under the Securities
Act and will be bound by the provisions of the Registration Rights Agreement
(including certain indemnification rights and obligations).
 
  Each holder of the Old Notes who wishes to exchange such Old Notes for
Exchange Notes in the Exchange Offer will be required to make certain
representations, including representations that (i) any Exchange Notes to be
received by it will be acquired in the ordinary course of its business, (ii)
it is not participating in, and it has no arrangement with any person to
participate in the distribution (within the meaning of the Securities Act) of
the Exchange Notes and (iii) it is neither an "affiliate" of SRH or the
Issuer, as defined in Rule 405 of the Securities Act, nor a broker-dealer
tendering Old Notes acquired directly from the Issuer for its own account. If
the holder is a broker-dealer that will receive Exchange Notes for its own
account in exchange for Old Notes that were acquired as a result of market-
making activities or other trading activities, it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Notes.
 
  The Registration Rights Agreement provides that: (i) unless the Exchange
Offer would not be permitted by applicable law or Commission policy, SRH and
the Issuer will file an Exchange Offer Registration Statement with the
Commission on or prior to 60 days after the date of original issuance of the
Notes (the "Closing Date"), (ii) unless the Exchange Offer would not be
permitted by applicable law or Commission policy, SRH and the Issuer will use
their best efforts to have the Exchange Offer Registration Statement declared
effective by the
 
                                      98
<PAGE>
 
Commission on or prior to 120 days after the Closing Date, (iii) unless the
Exchange Offer would not be permitted by applicable law or Commission policy,
the Issuer will commence the Exchange Offer and use commercially reasonable
best efforts to issue, on or prior to 30 business days after the date on which
the Exchange Offer Registration Statement was declared effective by the
Commission, Exchange Notes in exchange for all Notes tendered prior thereto in
the Exchange Offer and (iv) if obligated to file the Shelf Registration
Statement, SRH and the Issuer will file on or prior to the later of (x) 90
days after the Closing Date or (y) 30 days after such filing obligation arises
and use their best efforts to cause the Shelf Registration Statement to be
declared effective by the Commission on or prior to 90 days after such
obligation arises; provided that if the Issuer has not consummated the
Exchange Offer within 180 days of the Closing Date, then SRH and the Issuer
will file the Shelf Registration Statement with the Commission on or prior to
the 181st day after the Closing Date and use its best efforts to cause the
Shelf Registration Statement to be declared effective within 60 days after
such filing. SRH and the Issuer will be required to use their best efforts to
keep such Shelf Registration Statement continuously effective, supplemented
and amended until the second anniversary of the Closing Date or such shorter
period that will terminate when all the Transfer Restricted Notes covered by
the Shelf Registration Statement have been sold pursuant thereto.
 
  If (i) SRH and the Issuer fail to file any of the registration statements
required by the Registration Rights Agreement on or before the date specified
for such filing, (ii) any of such registration statements is not declared
effective by the Commission or prior to the date specified for such
effectiveness (the "Effectiveness Target Date"), (iii) the Issuer fails to
consummate the Exchange Offer within 30 business days of the Effectiveness
Target Date with respect to the Exchange Offer Registration Statement, or (iv)
the Shelf Registration Statement or the Exchange Offer Registration Statement
is declared effective but thereafter, subject to certain exceptions, ceases to
be effective or usable in connection with the Exchange Offer or resales of
Transfer Restricted Notes, as the case may be, during the periods specified in
the Registration Rights Agreement (each such event referred to in clauses (i)
through (iv) above, a "Registration Default"), then the interest rate on
Transfer Restricted Notes will increase ("Additional Interest"), with respect
to the first 90-day period immediately following the occurrence of such
Registration Default by 0.50% per annum and will increase by an additional
0.50% per annum with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of 2% per annum
with respect to all Registration Defaults. Following the cure of all
Registration Defaults, the accrual of Additional Interest will cease and the
interest rate will revert to the original rate.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a general discussion of certain U.S. federal income tax
considerations relevant to holders of the Notes. This discussion is based upon
the Internal Revenue Code of 1986, as amended (the "Code"), Treasury
Regulations, Internal Revenue Service ("IRS") rulings and judicial decisions
now in effect, all of which are subject to change (possible with retroactive
effect) or different interpretations. This discussion does not purport to deal
with all aspects of federal income taxation that may be relevant to a
particular investor's decision to purchase the Notes, and it is not intended
to be wholly applicable to all categories of investors, some of which, such as
dealers in securities, banks, insurance companies and tax-exempt
organizations, may be subject to special rules. In addition, this discussion
is limited to persons that will hold the Notes represented thereby as a
"capital asset" within the meaning of section 1221 of the Code.
 
INTEREST INCOME
 
  Interest on the Notes will be includable in the income of a holder under the
holder's regular method of accounting. The Notes will not be treated as having
been issued with original issue discount.
 
MARKET DISCOUNT
 
  Investors acquiring Notes pursuant to this Prospectus should note that the
resale of the Notes may be adversely affected by the market discount
provisions of sections 1276 through 1278 of the Code. Under the market
discount rules, if a holder of a Note (other than a holder who purchased the
Note upon original issuance) purchases it at a market discount (i.e., at a
price below its stated redemption price at maturity) in excess of a
statutorily-defined de minimis amount and thereafter recognizes gain upon a
disposition or retirement of the Note, then the lesser of the gain recognized
or the portion of the market discount that accrued on a ratable basis (or, if
elected, on a constant interest rate basis) generally will be treated as
ordinary income at the time of the disposition. Moreover, any market discount
in a Note may be taxable to an investor to the extent of appreciation at the
time of certain otherwise non-taxable transactions (e.g., gifts). Absent an
election to include market discount in income as it accrues, a holder of a
market discount debt instrument may be required to defer a portion of any
interest expense that otherwise may be deductible on any indebtedness incurred
or maintained to purchase or carry such debt instrument until the holder
disposes of the debt instrument in a taxable transaction.
 
SALE, EXCHANGE OR RETIREMENT OF THE NOTES
 
  Each holder of Notes generally will recognize gain or loss upon the sale,
exchange, repurchase, redemption, retirement or other disposition of those
Notes measured by the difference (if any) between (i) the amount of cash and
the fair market value of any property received (except to the extent that such
cash or other property is attributable to the payment of accrued interest not
previously included in income, which amount will be taxable as ordinary
income) and (ii) the holder's adjusted tax basis in those Notes (including any
market discount previously included in income by the holder). Any such gain or
loss recognized on the sale, exchange, repurchase, redemption, retirement or
other disposition of a Note should be capital gain or loss (except as
discussed under "Market Discount" above), and would be long-term capital gain
or loss if the Note had been held for more than one year at the time of the
sale or exchange. If the Notes had been held by a noncorporate holder for more
than 12 months but not more than 18 months, such capital gains generally shall
be subject to tax at a maximum 28% rate. If the Notes had been held for more
than 18 months, however, such capital gain generally will be subject to tax at
a maximum 20% rate. An investor's initial basis in a Note will be the cash
price it paid therefor.
 
BACKUP WITHHOLDING
 
  A holder of Notes may be subject to "backup withholding" at a rate of 31%
with respect to certain "reportable payments," including interest payments
and, under certain circumstances, principal payments on the Notes. These
backup withholding rules apply if the holder, among other things, (i) fails to
furnish a social security number or other taxpayer identification number
("TIN") certified under penalties of perjury within a
 
                                      100
<PAGE>
 
reasonable time after the request therefor, (ii) furnishes an incorrect TIN,
(iii) fails to report properly interest, or (iv) under certain circumstances,
fails to provide a certified statement, signed under penalties of perjury,
that the TIN furnished is the correct number and that such holder is not
subject to backup withholding. A holder who does not provide the Issuer with
its correct TIN also may be subject to penalties imposed by the IRS. Any
amount withheld from a payment to a holder under the backup withholding rules
is creditable against the holder's federal income tax liability, provided that
the required information is furnished to the IRS. Backup withholding will not
apply, however, with respect to payments made to certain holders, including
corporations, tax-exempt organizations and certain foreign persons ("exempt
recipients"), provided their exemptions from backup withholding are properly
established.
 
  The amount of any "reportable payments" including interest made to the
holders of Notes (other than to holders which are exempt recipients) and the
amount of tax withheld, if any, with respect to such payments will be reported
to such holders and to the IRS for each calendar year.
 
FOREIGN HOLDERS
 
  The following discussion is a summary of certain U.S. federal income tax
consequences to a Foreign Person that holds a Note. The term "Foreign Person"
means a nonresident alien individual or foreign corporation, but only if the
income or gain on the Note is not "effectively connected with the conduct of a
trade or business within the U.S." If the income or gain on the Note is
"effectively connected with the conduct of a trade or business within the
U.S.," then the nonresident alien individual or foreign corporation will be
subject to tax on such income or gain in essentially the manner as a U.S.
citizen or resident or a domestic corporation, as discussed above, and in the
case of a foreign corporation, may also be subject to the branch profits tax.
 
  Under the portfolio interest exception to the general rules for the
withholding of tax on interest paid to a Foreign Person, a Foreign Person will
not be subject to U.S. federal income tax (or to withholding) on interest
payments on a Note, provided that (i) the Foreign Person does not actually or
constructively own 10% or more of the total combined voting power of all
classes of stock of the Issuer entitled to vote and is not a controlled
foreign corporation with respect to the U.S. that is related to the Issuer
through stock ownership and (ii) the Issuer, its paying agent or the person
who would otherwise be required to withhold tax received either (A) a
statement (an "Owner's Statement") signed under penalties of perjury by the
beneficial owner of the Note in which the owner certifies that the owner is
not a U.S. person, or in the case of an individual, that he is neither a
citizen nor a resident of the United States, and which provides the owner's
name and address, or (B) a statement signed under penalties of perjury by the
Financial Institution holding the Note on behalf of the beneficial owner,
together with a copy of the Owner's Statement. The term "Financial
Institution" means a securities clearing organization, bank or other financial
institution that holds customers' securities in the ordinary course of its
trade or business and that holds a Note on behalf of the owner of the Note. A
Foreign Person who does not qualify for the "portfolio interest" exception,
would, under current law, generally be subject to U.S. federal withholding tax
at a flat rate of 30% (or lower applicable treaty rate) on interest payments.
 
  In general, gain recognized by a Foreign Person upon the redemption, sale or
exchange of a Note (including any gain representing accrued market discount)
will not be subject to U.S. federal income tax. However, a Foreign Person may
be subject to U.S. federal income tax at a flat rate of 30% (unless exempt by
an applicable treaty) on any such gain if the Foreign Person is an individual
present in the U.S. for 183 days or more during the taxable year in which the
Note is redeemed, sold or exchanged, and certain other requirements are met.
 
EXCHANGE OFFER
 
  The exchange of the Exchange Notes for the Notes pursuant to this Offer will
not be treated as an "exchange" for U.S. federal income tax purposes because
the Exchange Notes will not be considered to differ materially in kind or
extent from the Old Notes. Rather, the Exchange Notes received by a holder
will be treated as a continuation of the Old Notes in the hands of such
holder. As a result, there will be no U.S. federal income tax consequences to
holders exchanging the Old Notes for the Exchange Notes pursuant to this
Offer. The holder must continue to include stated interest in income as if the
exchange had not occurred. Similarly, there would be no U.S. federal income
tax consequences to a holder of Old Notes that does not participate in the
Exchange Offer.

<PAGE>
 
                             PLAN OF DISTRIBUTION
 
  Prior to the Initial Offering, there was no market for the Notes. The Notes
are not listed on a national securities exchange or authorized for trading on
the National Association of Securities Dealers Automated Quotation System. The
Old Notes sold to QIBs are eligible for trading in the PORTAL market. The
Issuer has been advised by the Initial Purchasers that the Initial Purchasers
currently intend to make a market in the Exchange Notes; however, they are not
obligated to do so and any market making may be discontinued by the Initial
Purchasers at any time. Therefore, there can be no assurance that an active
market for the Old Notes or the Exchange Notes will develop.
 
  The Initial Purchasers may have engaged in transactions that stabilize,
maintain or otherwise affect the price of the Notes. Specifically, the Initial
Purchasers may have overalloted in connection with the Private Placement,
creating a short position in the Old Notes for its own account. In addition,
to cover over-allotments or to stabilize the price of the Old Notes, the
Initial Purchasers may bid for, and purchase, Old Notes in the open market.
Any of these activities may stabilize or maintain the market price of the Old
Notes above independent market levels. The Initial Purchasers were not
required to engage in these activities, and may end any of these activities at
any time.
 
  If a trading market develops for the Old Notes or the Exchange Notes, future
trading prices of such securities will depend on many factors, including,
among other things, prevailing interest rates, the Company's results of
operations and the market for similar securities. Depending on such factors,
such securities may trade at a discount from their offering price.
 
  Certain of the Initial Purchasers and their respective affiliates provide or
have provided banking, advisory and other financial services for the Company
in the ordinary course of business. Banc One Capital Corporation is an
affiliate of Bank One, Texas, N.A. ("Bank One"). Bank One is a lender under
the Southwest Credit Facility and received its proportionate share (82%) of
the repayment by the Issuer of borrowings thereunder from the net proceeds of
the Private Placement. Paribas Corporation is an affiliate of Banque Paribas.
Banque Paribas is a lender under the Southwest Credit Facility and received
its proportionate share (18%) of the repayment of the Issuer of borrowings
thereunder from the net proceeds of the Private Placement.
 
  Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. This Prospectus, as it may
be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Notes received in exchange for Old
Notes where such Old Notes were acquired as a result of market-making
activities or other trading activities. The Issuer and SRH have agreed that,
starting on the Expiration Date and ending on the close of business 180 days
after the Expiration Date, they will make this Prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any
such resale. A broker-dealer that delivers such a prospectus to purchasers in
connection with such resales will be subject to certain of the civil liability
provisions under the Securities Act and will be bound by the provisions of the
Registration Agreement (including certain indemnification rights and
obligations). In addition, for 180 days after the completion of the Exchange
Offer, all dealers effecting transactions in the Exchange Notes may be
required to deliver a prospectus.
 
  Neither the Issuer nor SRH will receive any proceeds from any sale of
Exchange Notes by broker-dealers. Exchange Notes received by broker-dealers
for their own account pursuant to the Exchange Offer may be sold from time to
time in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such
Exchange Notes. Any broker-dealer that resells Exchange Notes that were
received by it for its own account pursuant to the Exchange Offer and any
broker or dealer that participates in a distribution of such Exchange Notes
may be deemed to be an "underwriter" within the meaning of the Securities Act
and any profit on any such resale of
 
                                      102
<PAGE>
 
Exchange Notes and any commissions or concessions received by any such persons
may be deemed to be underwriting compensation under the Securities Act. The
Letter of Transmittal states that by acknowledging that it will deliver and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.
 
  For a period of 180 days after the Expiration Date, the Issuer will promptly
send additional copies of this Prospectus to any broker-dealer that requests
such documents in the Letter of Transmittal. The Issuer and SRH have agreed in
the Registration Rights Agreement to pay all expenses incident to the Exchange
Offer other than commissions or concessions of any brokers or dealers and to
indemnify the holders of the Old Notes (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.

                      TRANSFER RESTRICTIONS ON OLD NOTES
 
OFFERS AND SALES BY THE INITIAL PURCHASERS
 
  The Old Notes have not been registered under the Securities Act and may not
be offered or sold in the United States, or to, or for the account or benefit
of, U.S. persons except in accordance with an applicable exemption from the
registration requirements thereof. Accordingly the Old Notes were being
offered and sold only to Qualified Institutional Buyers (as defined in Rule
144A under the Securities Act) ("QIBs") under Rule 144A under the Securities
Act and other Institutional Accredited Investors in a private sale exempt from
the registration requirements of the Securities Act.
 
INVESTOR REPRESENTATIONS AND RESTRICTIONS ON RESALE
 
  Each purchaser of the Old Notes was deemed to have represented and agreed as
follows:
 
    (1) it was acquiring the Old Notes for its own account or for an account
  with respect to which it exercises sole investment discretion, and that it
  or such account is a QIB or an Institutional Accredited Investor acquiring
  the Old Notes for investment purposes and not for distribution;
 
    (2) it acknowledged that the Old Notes had not been registered under the
  Securities Act and could not be offered or sold except as permitted below;
 
    (3) it understood and agreed (x) that such Old Notes were being offered
  only in a transaction not involving any public offering within the meaning
  of the Securities Act, and (y) that (A) if within two years after the date
  of original issuance of the Old Notes or if within three months after it
  ceases to be an affiliate (within the meaning of Rule 144 under the
  Securities Act) of the Issuer, it decided to resell, pledge or otherwise
  transfer the Old Notes on which the legend set forth below appears, such
  Old Notes may be resold, pledged or transferred only (i) to the Issuer,
  (ii) so long as such securities are eligible for resale pursuant to Rule
  144A, to a person whom the seller reasonably believes is a QIB that
  purchases for its own account or for the account of a QIB to whom notice is
  given that the resale, pledge or transfer is being made in reliance on Rule
  144A (as indicated by the box checked by the transferor on the Certificate
  of Transfer on the reverse of the Old Note if such Old Note is not in book-
  entry form), (iii) to an Institutional Accredited Investor (as indicated by
  the box checked by the transferor on the Certificate of Transfer on the
  reverse of the Old Note if such Old Note is not in book-entry form) who has
  certified to the Issuer and the Trustee for the Old Notes that such
  transferee is an Institutional Accredited Investor and is acquiring the Old
  Notes for investment purposes and not for distribution, (iv) pursuant to an
  exemption from the registration requirements of the Securities Act provided
  by Rule 144 (if applicable) under the Securities Act or (v) pursuant to an
  effective registration statement under the Securities Act, in each case in
  accordance with any applicable securities laws of any state of the United
  States, (B) the initial purchaser, and each subsequent holder is required
  to, notify any purchaser of the Old Notes from it of the resale
  restrictions referred to in (A) above, if then applicable, and (C) with
  respect to any transfer of the Old Notes by an Institutional Accredited
  Investor, such holder will deliver to the Issuer and the Trustee such
  certificates and other information as they may reasonably require to
  confirm that the transfer by it complies with the foregoing restrictions;
 
    (4) it understands that the notification requirement referred to in (3)
  above will be satisfied, in the case only of transfers by physical delivery
  of Certificated Securities other than a Global Note by virtue of the fact
  that the following legend will be placed on the Old Notes unless otherwise
  agreed by the Issuer:
 
    "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,

  IT WILL FURNISH TO THE ISSUER AND THE TRUSTEE SUCH CERTIFICATES AND OTHER
  INFORMATION AS THEY MAY REASONABLY REQUIRE TO CONFIRM THAT ANY TRANSFER BY
  IT OF THIS NOTE COMPLIES WITH THE FOREGOING RESTRICTIONS. THE HOLDER
  HEREOF, BY PURCHASING THIS NOTE, REPRESENTS AND AGREES FOR THE BENEFIT OF

  DATED AS OF OCTOBER 14, 1997, AMONG THE COMPANY, THE ISSUER, JEFFERIES &
  COMPANY, INC., BANC ONE CAPITAL CORPORATION AND PARIBAS CORPORATION, A COPY
  OF WHICH IS ON FILE WITH THE SECRETARY OF THE ISSUER."
 
    (5) it (i) has such knowledge and experience in financial and business
  matters as to be capable of evaluating the merits and risks of its
  prospective investment in the Old Notes and (ii) has the ability to bear
  the economic risks of its prospective investment and can afford the
  complete loss of such investment;
 
    (6) it had received a copy of the Offering Circular relating to the
  offering of the Old Notes and acknowledges that it has had access to such
  financial and other information, and has been afforded the opportunity to
  ask questions of the Issuer and receive answers thereto, as it deemed
  necessary in connection with its decision to purchase the Old Notes; and
 
    (7) it understood that the Issuer, the Initial Purchasers and others will
  rely upon the truth and accuracy of the foregoing acknowledgments,
  representations and agreements and agreed that if any of the
  acknowledgments, representations and warranties deemed to have been made by
  it by its purchase of the Old Notes are no longer accurate, it shall
  promptly notify the Issuer and the Initial Purchasers. If it acquired the

  The unaudited pro forma combined financial statements have been prepared to
give effect to the issuance of the Old Notes, as issued on October 14, 1997,
and the application of net proceeds therefrom, the Transactions, certain
completed and pending acquisitions of Southwest and Red Oak (to the extent not
already reflected in the consolidated financial statements of the Company) and
the exchange of the Old Notes for New Notes (having no significant effects on
the unaudited pro forma combined financial statements) as if such transactions
had taken place on September 30, 1997 with respect to the unaudited pro forma
combined balance sheet, and as of January 1, 1996 with respect to the
unaudited pro forma combined statements of operations.
 
  The unaudited pro forma combined financial statements included herein are
not necessarily indicative of the results that might have occurred had the
transactions taken place at the date specified and are not intended to be a
projection of future results. In addition, future results may vary
significantly from the results reflected in the accompanying unaudited pro
forma combined financial statements because of normal production declines,
changes in product prices, future acquisitions and divestitures, changes in
the real estate market, and other factors.
 
  The following unaudited pro forma combined financial statements should be
read in conjunction with the consolidated financial statements and the related
notes of the Company.

2. PRO FORMA ENTRIES
 
  (a) To record the issuance of $200.0 million of 10 1/2% Senior Notes due
2004, including net proceeds of approximately $190.0 million, debt issuance
costs of approximately $7.6 million and discount of $2.4 million.
 
  (b) To record the repayment of existing Southwest debt of approximately
$77.7 million and related accrued interest of approximately $3.1 million and
prepayment penalties of approximately $1.8 million. The loss on the
extinguishment of debt will be reported as an extraordinary item, net of
related tax effect.
 
  (c) To record the Oil and Gas Properties Acquisition using the purchase
method of accounting. The allocation of the purchase price to the acquired
assets and liabilities is preliminary and, therefore, subject to change.

    NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
                   DECEMBER 31, 1996 AND SEPTEMBER 30, 1997
  (d) To record the Company's additional investment of $1,699,000 in a
partnership of which Southwest serves as general partner. The partnership's
primary asset is its investment in Sierra.
 
  (e) To record the Red Oak Acquisitions using the purchase method of
accounting and to record incremental borrowings under the MROP Facility and
additional mortgage facilities. The allocation of each purchase price to the
acquired assets and liabilities is preliminary and, therefore, subject to
change.
 
  (f) To record the write-off of deferred debt costs related to the Existing
Debt. This write-off will be treated as a loss or extinguishment of debt and
reported as an extraordinary item, net of related tax effects.
 
  (g) To eliminate the oil and gas revenues and production costs associated
with the tertiary recovery (CO2) project on the Oil and Gas Properties
Acquisition. The Company's acquisition of the Oil and Gas Properties
Acquisition did not include the business of the tertiary recovery project. The
seller of the Oil and Gas Properties Acquisition was involved in a CO2 project
which the Company explicitly did not acquire. The principle tangible assets
and liabilities of the CO2 project were pipeline imbalances which the Company
did not acquire.
 
  (h) To record estimated incremental depletion expense on the Oil and Gas
acquisitions.
 
  (i) To record estimated incremental depreciation expense on the Red Oak
acquisitions.
 
  (j) To record incremental interest expense associated with the Senior Notes
including incremental interest associated with the Oil and Gas acquisitions,
amortization of the estimated debt issue costs of $7 million over the life of
the Senior Notes and the reversal of interest recognized on the debt of
Southwest to be retired with the proceeds of the Senior Notes. A 1/8% change
in interest rate on such notes would result in a $225,000 change in annual
interest expense.
 
  (k) To record incremental interest associated with borrowings used to
finance the Red Oak Acquisitions. The associated notes are generally for 20
years with interest ranging from 9.25% to 13.00% and loan origination costs
from 1% to 3% of the respective note amounts.
 
  (l) To adjust pro forma income tax expense.
 
  (m) To reflect the deconsolidation of Sierra. On July 1, 1997, additional
common stock of Sierra was sold to a partnership. As a consequence, the
Company no longer has majority voting control of Sierra. Southwest is the
general partner of the partnership.

5. OIL AND GAS RESERVE DATA
 
  The following unaudited pro forma supplemental information regarding the oil
and gas activities of Southwest is presented pursuant to the disclosure
requirements promulgated by the Commission and Statement of Financial
Accounting Standards No. 69, "Disclosures About Oil and Gas Producing
Activities". The pro forma combined reserve information is presented as if the
acquisition of the oil and gas interests described above had occurred on
January 1, 1996.
 
  Management emphasizes that reserve estimates are inherently imprecise and
subject to revision and that estimates of new discoveries are more imprecise
than those of producing oil and gas properties. Accordingly, the estimates are
expected to change as future information becomes available. Such changes could
be significant.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
Southwest Royalties Holdings, Inc.:
 
  We have audited the accompanying consolidated balance sheet of Southwest
Royalties Holdings, Inc. and subsidiaries as of December 31, 1996, and the
related consolidated statement of operations, stockholders' equity and cash
flows for the year then ended. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Southwest
Royalties Holdings, Inc. and subsidiaries as of December 31, 1996, and the
results of their operations and their cash flows for the year then ended, in
conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Business
 
   Southwest Royalties Holdings, Inc. ("SRH"), a Delaware corporation was
formed in June 1997 to serve as a holding company for Southwest Royalties Inc.
("Southwest"), Sierra Well Service Inc. ("Sierra") and Midland Red Oak Realty,
Inc. ("Red Oak") (collectively, the "Company"). Each shareholder of Southwest
was issued the exact same amount of shares in SRH as they had held in
Southwest so that the ownership in SRH was the same as it was in Southwest
before and after the formation of SRH. Southwest then dividended 100% of the
shares it owned in Red Oak and Sierra up to SRH. Prior to the formation of
SRH, Red Oak and Sierra were subsidiaries of Southwest. After the formation of
SRH, Southwest and Red Oak became subsidiaries of SRH, and as of July 1, 1997,
Sierra was deconsolidated. See Note 3.
 
  Southwest is principally involved in the business of oil and gas development
and production, as well as organizing and serving as managing general partner
for various public and private limited partnerships engaged in oil and gas
acquisitions, exploration, development and production. Southwest is also the
general partner of Southwest Partners II and III, which own common stock in
Sierra. Southwest sells its oil and gas production to a variety of purchasers,
with the prices it receives being dependent upon the oil and gas commodity
prices. Red Oak is principally involved in real estate investment and
development. Sierra is principally involved in the business of oil and gas
well services, which include plugging and workovers for wells.
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of SRH and its
subsidiaries, each of which are wholly owned, except Red Oak, Sierra and
Threading Products International, LLC ("TPI" (a subsidiary of Southwest)). As
of December 31, 1995 and 1996, the Company owned approximately 78% and 76% of
Red Oak, 99% and 54% of Sierra and 95% of TPI. Effective July 1997, Southwest
Partners III purchased additional shares of Sierra stock thus decreasing the
Company's total direct and indirect ownership percentage to 45%. Therefore,
effective July 1, 1997, Sierra was deconsolidated and is reported upon using
the equity method (see Note 3). The consolidated financial statements include
the Company's proportionate share of the assets, liabilities, income and
expenses of oil and gas limited partnerships for which it serves as managing
general partner. All significant intercompany transactions have been
eliminated.
 
 Estimates and Uncertainties
 
  Preparation of the accompanying consolidated financial statements in
conformity with generally accepted accounting principles requires management
to make estimates and assumptions that affect the reported amounts of assets
and liabilities and disclosures of contingent assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents. In addition, the
Company maintains its excess cash in several interest bearing accounts in
various financial institutions.
 
 Concentrations of Credit Risk
 
  The Company is subject to credit risk through trade receivables. Although a
substantial portion of its debtors' ability to pay is dependent upon the oil
and gas industry, credit risk is minimized due to a large customer base.
 
 Oil and Gas Properties
 
  All of the Company's oil and gas properties are located in the United States
and are accounted for at cost under the full cost method. Under this method,
all productive and nonproductive costs incurred in connection

with the acquisition, exploration and development of oil and gas reserves are
capitalized. No gain or loss is recognized on the sale of oil and gas
properties unless nonrecognition would significantly alter the relationship
between capitalized costs and remaining proved reserves for the affected
amortization base. When gain or loss is not recognized, the amortization base
is reduced by the amount of sales proceeds.
 
  Net capitalized costs of oil and gas properties, including the estimated
future costs to develop proved reserves, are amortized using the units of
revenue method, whereby the provision is computed on the basis of current
gross revenues from production in relation to future gross revenues, based on
current prices, from estimated production of proved oil and gas reserves.
Should the net capitalized costs net of related deferred income taxes exceed
the estimated present value of oil and gas reserves discounted at 10% and
adjusted for related income taxes, such excess costs would be charged to
expense in the Consolidated Statements of Operations.
 
  It is reasonably possible that the estimates of anticipated future gross
revenues, the remaining estimated economic life of the product, or both could
change significantly in the near term due to the potential fluctuation of oil
and gas prices or production. Depletion estimates would also be affected by
such changes.
 
 Property and Equipment
 
  Oil and gas well servicing equipment, rental property and other property and
equipment is stated at cost. Repairs and maintenance are charged to expense as
incurred, with additions and improvements being capitalized. Upon sale or
other retirement of depreciable property, the cost and accumulated
depreciation are removed from the related accounts and any gain or loss is
reflected in the Consolidated Statements of Operations.
 
  Depreciation is provided on the straight-line method based on the estimated
useful lives of the depreciable assets as listed below:

 Real Estate Investments
 
  The Company is a limited partner in various limited partnerships, which are
carried at cost. No earnings have been distributed to the Company from these
partnerships.
 
 Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of
 
  The Company adopted the provisions of SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,
on January 1, 1996. This Statement requires that long-lived assets and certain
identifiable intangibles be reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. Adoption of this Statement did not have an impact on the
Company's financial position, results of operations, or liquidity.
 
 Deferred Debt Costs
 
  The Company capitalizes certain cost incurred in connection with obtaining
debt. These costs are being amortized to interest expense on the straight-line
method over the term of the related debt.

 Gas Balancing
 
  The Company utilizes the sales method of accounting for over or under
deliveries of natural gas. Under this method, the Company recognizes sales
revenue on all natural gas sold. As of December 31, 1995 and December 31,
1996, the Company was underproduced by approximately 990 and 693 MMcf,
respectively.
 
 Income Taxes
 
  Deferred tax assets and liabilities are recognized for the estimated future
tax effects attributable to differences between the financial statement
carrying amount of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on
deferred tax assets and liabilities of a change in tax rate is recognized in
income in the period that includes the enactment date. Deferred tax assets are
reduced, if necessary, by a valuation allowance for the amount of tax benefits
that may not be realized.
 
  SRH and its eligible subsidiaries file a consolidated U.S. federal income
tax return. Sierra and Red Oak are consolidated for financial reporting
purposes, but beginning January 1, 1996, were not eligible to be included in
the consolidated U.S. federal income tax return. Separate provisions for
income taxes have been determined for these entities.
 
 Reclassifications
 
  Certain reclassifications have been made to the 1994 and 1995 amounts to
conform to the 1996 presentation.
 
 Earnings (Loss) Per Share
 
  Net earnings (loss) per share is computed using the weighted average number
of shares of common stock and redeemable common stock outstanding. Common
equivalent shares from warrants are excluded from the computation as their
exercise price is equivalent to the fair market value of the common stock and
there would be no dilution under the treasury stock method.
 
 Interim Financial Statements
 
  The interim financial information as of September 30, 1997, and for the nine
months ended September 30, 1996 and 1997, is unaudited. However, in the
opinion of management, these interim financial statements include all the
necessary adjustments to fairly present the results of the interim periods,
and all such adjustments are of a normal recurring nature. The interim
financial statements should be read in conjunction with the audited financial
statements for the years ended December 31, 1994, 1995 and 1996.
 
2. SUBSIDIARIES, ACQUISITIONS AND DISPOSITIONS
 
  During 1994, Red Oak sold 62,384 shares of redeemable common stock for
approximately $1,560,000 through a private placement offering. During 1995,
Red Oak sold an additional 39,616 shares of redeemable common stock for
approximately $990,000 and 34,611 shares of its Series A cumulative
convertible preferred stock for approximately $1,731,000. The redeemable
common stock is redeemable at the stockholder's option at a price equal to the
purchase price plus a 6% annual return computed on a cumulative, but not
compounded, basis between December 1, 1996 and December 1, 1999. Redemptions
are to be paid out of future earnings of Red Oak. If there are no future
earnings, redemptions will be paid out of additional paid-in capital.

  On August 2, 1995, SW Espero, Inc., a wholly owned subsidiary of Southwest,
acquired all of the stock of Espero Energy Corporation for approximately
$13,000,000, which was funded through a credit agreement with an asset
management company. SW Espero, Inc. and Espero Energy Corporation were
immediately merged, with Espero Energy Corporation being the surviving
corporation. The acquisition was accounted for as a purchase and the total
purchase price was allocated to the assets and liabilities acquired based upon
their estimated respective fair market values. The results of operations of
Espero Energy Corporation are included in the Consolidated Statements of
Operations beginning August 2, 1995.
 
  On September 26, 1996, Red Oak formed a subsidiary with an unrelated third
party. On October 15, 1996, the subsidiary acquired three shopping centers for
a total purchase price of $12.5 million. The transaction was funded through a
$2.3 million contribution from Red Oak and a $1.2 million contribution from
the unrelated third party. The subsidiary funded the remaining $9 million of
the purchase price through a note payable due June 1, 1998. (See Note 6). The
transaction was accounted for using the purchase method. The results of
operations of the properties acquired are included in the Consolidated
Statements of Operations beginning September 26, 1996.

3. INVESTMENT
 
  The investment in subsidiary held by the Company consists of a 45% ownership
interest in Sierra Well Service, Inc. The investment is accounted for on the
equity method. Effective July 1997, Southwest Partners III purchased
additional shares of Sierra stock thus decreasing Southwest's total direct and
indirect ownership percentage. Therefore, with the change of Southwest's
ownership percentage from a majority to a minority interest, Sierra was
deconsolidated. The deconsolidation of Sierra required an adjustment to the
investment account to reflect the change in accounting from the consolidation
method to the equity method.

September 30, 1997 and for the quarter ended September 30, 1997 is as follows:

 Revolving Line of Credit
 
  The revolving credit line allows Southwest to borrow the lesser of $75
million or the borrowing base which is renegotiated periodically. As of
December 31, 1996, the borrowing base was $28,125,000, and as of September 30,
1997, the borrowing base was $44,900,000. The revolving line of credit
agreement provides for the revolver to become due and payable on February 28,
1999. Fees on the unused portion of the revolving line of credit are three-
eighths of one percent ( 3/8%) per annum on the daily average of the
unadvanced amount of the borrowing base.
 
  Southwest has the option to elect an interest rate based on LIBOR plus the
applicable Eurodollar Margin or Prime plus a base rate margin. Both margins
are based on the percentage of the revolving commitment

outstanding. The Eurodollar Margin ranges from a minimum of 1.75% to a maximum
of 2.50% and the Prime base rate margin ranges from a minimum of .25% to a
maximum of 1.00%. At December 31, 1996 the Company had chosen the LIBOR rate
election for approximately $28 million of its then outstanding balance on the
revolving line of credit. The LIBOR elections ranged from 7.50% to 8.44%.
 
  Certain covenants of the revolving line of credit require a tangible net
worth of not less than $2 million, a current ratio of 1.0 to 1, a minimum
fixed coverage ratio of 1.1 to 1, restrictions on cash dividends, additional
indebtedness and purchases of investments. Substantially all of Southwest's
assets are collateralized in connection with this debt. Southwest was in
violation of several covenants as of December 31, 1996 and September 30, 1997,
and obtained waivers of the covenants from the lender for the December 31,
1996 violations. Effective June 30, 1997, the lender amended the current ratio
to 0.84 to 1, until September 30, 1997, at which time the ratio becomes 1.0 to
1, and amended the minimum fixed charge ratio to 1.0 to 1, until July 1, 1998,
at which time the ratio becomes 1.1 to 1. Management believes that it is
likely the Company will comply with these covenants as amended.
 
 9% Notes Payable
 
  In August 1995, a subsidiary of Southwest entered into a note agreement
which provided for $30,305,000 in five senior secured amortizing term notes,
having a stated interest of 9%, with quarterly payments which include
interest. These quarterly payments consist of all excess cash balances over
$500,000, less any funds advanced under the notes and unused for the
development of oil and gas properties. The notes are due December 31, 2003,
and are collateralized by certain oil and gas properties.
 
  The covenants of the note agreement include: (1) a working capital base that
is never less than $100,000 at any time after December 31, 1995, $250,000 at
any time after March 31, 1996, and $500,000 at and after June 27, 1996; and
(2) an interest coverage ratio that is never less than 150% at any time after
December 31, 1995. The covenants are based on the subsidiary's financial
statements.
 
  One of the terms of the note agreement provides for an initial 7% gross
overriding royalty interest conveyance in all oil and gas properties of the
subsidiary which shall be adjusted upward to a maximum of 9.95% or downward to
a minimum of 4% on January 1, 1998 in order for a 15.75% internal rate of
return to be achieved on December 31, 2003.
 
 10% Note Payable
 
  In October 1996, Red Oak, through a subsidiary, negotiated a term note of
$9,000,000 to finance the purchase of real estate. This note was repaid with a
portion of the proceeds from the 13% note payable discussed below.
 
 12% Note Payable
 
  In November 1996, Southwest entered into a senior subordinated note
agreement which provided for $8,000,000 to be used for developmental drilling.
The note bears interest at a stated rate of 12%, payable semi-annually,
matures November 1, 2001, and is collateralized by oil and gas properties. The
note agreement contains certain restrictive covenants that include: (1) a
leverage ratio of combined adjusted net tangible assets to combined
indebtedness that is never less than 150% at any time after November, 1996;
and (2) investments in the form of loans and advances to various subsidiaries
are less than $1,200,000 in the aggregate and not outstanding for more than 90
days. Certain covenants also place restrictions on cash dividends, additional
indebtedness and investments, and compensation to certain key employees.

  As part of the above noted agreement, Southwest issued common stock warrants
which are exercisable in whole or in part any time prior to November 5, 2001.
These warrants had an estimated fair value of approximately $857,000. At
December 31, 1996, the lender was entitled to 45,413 warrants at an exercise
price of $68 per share.
 
 13% Notes Payable
 
  In April 1997, MRO Properties, Inc. ("MROP"), a wholly-owned subsidiary of
Red Oak, entered into a $42 million credit facility maturing in April 2000
with an institutional lender (the "MROP Facility"). The MROP Facility was
executed in order to consolidate six mortgage loans, originally incurred to
complete the acquisition of certain Red Oak properties and to finance the
acquisition of an additional real estate property. Borrowings under the
facility bear interest at a rate of 13% with 10% payable in cash and the
remaining 3% payable in cash or additional notes at MROP's option. The
facility contains a number of covenants that, among other things, restrict the
ability of MROP to incur additional indebtedness and dispose of assets. The
facility is secured by a first lien on substantially all of MROP's properties.
 
  The deferred debt costs associated with refinancing of the mortgage loans
were charged to expense as an extraordinary item. The amount relating to the
early extinguishment of debt approximated $490,000 which consisted of $742,000
in deferred debt charges with a related income tax benefit of $252,000.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  A valuation allowance is provided when it is more likely than not that some
portion of the deferred tax assets will not be realized. Based on expectations
for the future and the availability of certain tax planning strategies that
would generate taxable income to realize the net tax benefits, if implemented,
management has determined that taxable income of the Company will more likely
than not be sufficient to fully utilize available carryforwards prior to their
ultimate expiration.
 
  As of December 31, 1996, the Company had net operating loss carryforwards
for U.S. federal income tax purposes of approximately $7,309,000, which are
available to offset future regular taxable income, if any. The net operating
loss carryforwards expire in 2010 and 2011. The Company has alternative
minimum tax credit carryforwards totaling $170,000 to offset regular income
tax, which have no scheduled expiration date.
 
8. LEASES
 
  The Company rents office space on a month to month basis in a building that
it also manages. Rent expense totaled approximately $241,000, $295,000 and
$243,000 for the years ended December 31, 1994, 1995 and 1996, respectively.
 
9. PROFIT SHARING PLAN
 
  On January 1, 1991, the Company adopted an employee profit sharing plan that
is intended to provide participating employees with additional income upon
retirement. Employees may contribute between 1% and 15% of their base salary
up to a maximum of $9,240 for the years ended December 31, 1994 and 1995 and
$9,500 for the year ended December 31, 1996. For the years ended December 31,
1994, 1995 and 1996, the Company matched 20% of the employees' contributions.
For the year ended December 31, 1997, the Company will match 20% of the
employees' contributions. For subsequent years, the Company will make
contributions to the plan on a discretionary basis.
 
  Employee contributions are fully vested at all times. Employer contributions
are fully vested upon retirement or after five years of service. For the years
ended December 31, 1994, 1995 and 1996, the Company contributed approximately
$45,000, $54,000 and $60,000, respectively, to the plan.
 
10. STOCKHOLDERS' EQUITY
 
  In August 1996, the Company issued 129,046 shares of redeemable common stock
through a private placement offering for $68 per share. The stock is
redeemable at the stockholder's option at any time beginning five years from
the issuance of the stock (December 31, 2001) at a purchase price determined
as follows:
 
    (i) The Company shall review no less than five and no more than ten
  publicly traded oil and gas companies each with a market capitalization
  between $50 million and $150 million ("Public Company"). The Company shall
  determine the ratio of each Public Company's market capitalization to
  EBITDA for the most recent fiscal year. The Company shall then average such
  multiples and take this averaged multiple and apply it to the Company's
  EBITDA for the most recent fiscal year, to estimate a value for the
  Company's common stock.
 
    (ii) The Company will determine the multiple of the market capitalization
  of each Public Company relating to the present value of such Public
  Company's oil and gas reserves. Present value will be determined by
  discounting the expected net cash flow from the oil and gas reserves by
  10%. The Company will then take the average multiple based on this
  methodology and apply it to the present value of the Company's oil and gas
  reserves discounted by 10% to determine a value for the expected net cash
  flow from the Company's common stock.

  The Company will then take the average of (i) and (ii) to determine the
  value of the Company's common stock.
 
  The redemption right terminates on the effective date of any registration
statement filed with the Securities and Exchange Commission relative to the
offer and sale of the Company's common stock to the public.
 
  During 1994, the Company issued a 6% note to a stockholder. The note
requires semi-monthly payments of $5,500 and is collateralized by the
Company's common stock held by the stockholder.
 
11. COMMITMENTS AND CONTINGENCIES
 
  The partnership agreements relating to certain limited partnerships for
which Southwest serves as managing general partner provide for Southwest to
offer to repurchase such limited partner units. Under the terms of three of
the partnership agreements, Southwest is obligated to repurchase a maximum of
$100,000 annually of the units of limited partnerships' interests originally
outstanding. Under the terms of the other nine partnership agreements,
Southwest's obligation to repurchase units in any one year is limited to 10%
of the capital contributed by all of the respective limited partners. The
repurchase price is based on the discounted future revenues from oil and gas
reserves of the respective partnership and the value of other partnership
assets. Such amounts required for repurchase in connection with the acceptance
by a portion of the limited partners is approximately $4,833,000 at December
31, 1996. The total amount of limited partner unit repurchases for the years
ended December 31, 1995 and 1996 was approximately $176,000 and $378,000,
respectively.
 
  The Company is subject to extensive federal, state and local environmental
laws and regulations. These laws, which are constantly changing, regulate the
discharge of materials into the environment and may require the Company to
remove or mitigate the environmental effects of the disposal or release of
petroleum or chemical substances at various sites. Environmental expenditures
are expensed or capitalized depending on their future economic benefit.
Expenditures that relate to an existing condition caused by past operations
and that have no future economic benefits are expensed. Liabilities for
expenditures of a noncapital nature are expensed when environmental assessment
and/or remediation is probable and the costs can be reasonably estimated.
 
  Management recognizes a financial exposure that may require future
expenditures presently existing for oil and gas properties and other
operations. Other long-term liabilities at December 31, 1996 include $504,000
for estimated future remedial actions and cleanup costs. As of December 31,
1996, the Company has not been fined, cited or notified of any environmental
violations which would have a material adverse effect upon capital
expenditures, earnings or the competitive position in the oil and gas
industry. However, management does recognize that by the very nature of its
business, significant costs could be incurred to bring the Company into total
compliance. The amount of such future expenditures is not readily determinable
due to several factors, including the unknown magnitude of possible
contaminations, the unknown timing and extent of the corrective actions which
may be required, the determination of the Company's liability in proportion to
other responsible parties and the extent to which such expenditures are
recoverable from insurance or indemnifications from prior owners of the
Company's properties. It is reasonably possible this estimate could change
materially in the near term.
 
  In the normal course of its business, the Company is subject to pending or
threatened legal actions; in the opinion of management, any such matters will
be resolved without material effect on the Company's operations, cash flow, or
financial position.

12. RELATED PARTY TRANSACTIONS
 
  Southwest is the managing general partner for several public and private oil
and gas limited partnerships, with an officer of Southwest also serving as a
general partner for certain of the limited partnerships. As is usual in the
oil and gas industry, the operator is paid an amount for administrative
overhead attributable to operating such properties. As provided for in the
partnership agreements, such amounts paid by the partnerships to Southwest as
operator approximated $1,805,000, $2,039,000, and $2,139,000 for the years
ended December 31, 1994, 1995 and 1996, respectively. In addition, Southwest
and certain officers and employees may have an interest in some of the
partnership properties.
 
  Sierra performs various oilfield services for limited partnerships managed
by Southwest. Such services aggregated $292,000, $166,000 and $112,000 for the
years ended December 31, 1994, 1995 and 1996, respectively. Southwest also
receives management fees as well as reimbursement of administrative costs
attributable to serving as managing general partner of certain of the limited
partnerships, with such fees aggregating $1,318,000, $1,506,000 and $1,509,000
for the years ended December 31, 1994, 1995 and 1996, respectively.
 
13. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  The carrying amount of cash and cash equivalents, accounts receivable,
accounts payable and accrued expenses, other current assets and other current
liabilities approximates fair value because of the short maturity of these
instruments.
 
  Based on the borrowing rates currently estimated to be available to the
Company for loans with similar terms, the fair value of long-term debt
approximates the carrying amount as of December 31, 1995 and 1996.
 
14. LINES OF BUSINESS
 
  The Company operates in three major segments: Oil and Gas Activities (oil
and gas acquisition, development, exploration and production, as well as
organizing and serving as managing general partner for various public and
private limited partnerships engaged in oil and gas development and
production), Oil and Gas Well Servicing (provides well completion,
recompletion and production equipment, transportation services, tank supply
rental services and other support and well maintenance services to operating
oil and gas companies) and Real Estate Investment and Management (owns and
manages retail shopping centers and office buildings). Other items include
eliminations, manufacturing, computer service and broker/dealer.

17. SUBSEQUENT EVENTS
 
 Southwest
 
  In October 1997, Southwest Royalties Inc., a wholly owned subsidiary of
Southwest Royalties Holdings, Inc. issued $200,000,000 of 10 1/2% Senior Notes
due 2004. The proceeds from the sale of the notes were used to purchase
certain oil and gas properties and related assets and to cancel certain debt
held at September 30, 1997. The cancelled debt consisted of $44,900,000 on a
revolving line of credit, $26,338,000 on a 9% note payable and $7,229,000 on a
12% note payable. In consideration of the intent and ability to refinance
existing debt with the note offering, Southwest reclassified the above
mentioned debt at September 30, 1997 as non-current.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  In October 1997, Southwest used a portion of the proceeds from the above
note offering to purchase 250,000 shares of Red Oak's stock for a total of
$10,000,000. In connection with the purchase of the additional shares, Red Oak
became eligible to be included in the Company's consolidated U.S. federal
income tax return.
 
  Southwest is a general partner of Southwest Partners III, L.P., which was
formed May 12, 1997. Under the terms of the partnership agreement, Southwest
is required to make capital contributions equal to 10% of the total limited
partner capital contributions. To date, the limited partners have made capital
contributions of $16.3 million, and accordingly, the Company has a liability
to the Partnership in the amount of $1,625,675.
 
  In September 1997, Southwest entered into an agreement to acquire certain
oil and gas properties and related assets for $72,342,000, subject to closing
adjustments. The acquisition closed on October 14, 1997.
 
 Real Estate
 
  Subsequent to September 1997, Red Oak was committed to purchase three
shopping centers and one office building all located in Texas, for a combined
total of approximately $25,705,000. A total of $475,000 is being held in
escrow and will be applied to each respective purchase price upon closing.

RESERVE QUANTITY INFORMATION
 
  The estimates of the Company's proved oil and gas reserves, which are
located in the United States, are based on evaluations reviewed by independent
petroleum engineers. Reserves were estimated in accordance with guidelines
established by the U. S. Securities and Exchange Commission and the Financial
Accounting Standards
 
                                     F-34

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
Board, which require that reserve estimates be prepared under existing
economic and operating conditions with no provision for price and cost
escalations except by contractual arrangements. The reserve estimates at
December 31, 1996 assume an average oil price of $23.89 per Bbl (reflecting
adjustments for oil quality and gathering and transportation costs) and an
average gas price of $3.67 per Mcf (reflecting adjustments for BTU content,
gathering and transportation costs and gas processing and shrinkage).
 
  Oil and gas reserve quantity estimates are subject to numerous uncertainties
inherent in the estimation of quantities or proved reserves and the projection
of future rates of production and the timing of development expenditures. The
accuracy of such estimates is a function of the quality of available data and
of engineering and geological interpretation and judgement. Results of
subsequent drilling, testing and production may cause either upward or
downward revision of previous estimates. Further, the volumes considered to be
commercially recoverable fluctuate with the changes in prices and operating
costs. The Company emphasizes that reserve estimates are inherently imprecise
and that estimates of new discoveries are more imprecise than those of
currently producing oil and gas properties. Accordingly, these estimates are
expected to change, as additional information becomes available in the future

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS
 
  The standardized measure of discounted future net cash flows is computed by
applying year-end prices of oil and gas (with consideration of price changes
only to the extent provided by contractual arrangements) to the estimated
future production of proved oil and gas reserves less estimated future
expenditures (based on year-end costs) to be incurred in developing and
producing the proved reserves, discounted using a rate of 10% per year to
reflect the estimated timing of the future cash flows. Future income taxes are
calculated by comparing discounted future cash flows to the tax basis of oil
and gas properties plus available carryforwards and credits and applying the
current tax rates to the difference.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Discounted future cash flow estimates like those shown below are not
intended to represent estimates of the fair value of oil and gas properties.
Estimates of fair value should also consider probable reserves, anticipated
future oil and gas prices, interest rates, changes in development and
production costs and risks associated with future production. Because of these
and other considerations, any estimate of fair value is necessarily subjective
and imprecise.

1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  On September 10, 1997, Southwest Royalties, Inc. ("Southwest") entered into
a Purchase and Sale Agreement (the "Agreement") with a major oil company (the
"Oil Company") to acquire the interests in certain producing oil and gas
properties (the "Property") which are located in the Permian Basin of the
United States as described in Exhibit A, Schedule 1 to the Agreement.
 
  The accompanying statement of revenues and direct operating expenses
("Statement") was prepared from the historical accounting records of the Oil
Company (accrual basis, successful efforts method of accounting for oil and
gas activities, in accordance with generally accepted accounting principles).
 
  Complete financial statements, including a balance sheet, are not presented
as the Property was not maintained as a separate business unit and assets,
liabilities or indirect operating costs applicable to the Property were not
segregated. It is not practicable to identify all assets, liabilities or
indirect operating costs applicable to the Property.
 
  Oil revenues and associated direct operating expenses relate to the net
revenue interest and net working interest, respectively, in the Property. With
respect to gas sales, the sales method is used for recording revenues. Under
this approach, each party recognizes revenue based on sales actually made
regardless of its proportionate share of the related production. Gas
imbalances related to production on the Property do not have a material impact
on the Statement. Direct operating expenses include labor, repairs and
maintenance, fuel consumed and supplies utilized to operate and maintain the
wells, related equipment and facilities. The Statement does not include
general and administrative expenses, interest or provisions for depreciation,
depletion, amortization and dismantlement costs, or for taxes on income.
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
2. RELATED PARTY TRANSACTIONS
 
  Substantially all of the revenues, labor and other operating expenses relate
to transactions with the Oil Company. The Oil Company purchases a significant
portion of production from these leases based on the Oil Company's posted
prices for processing at its refineries. Services performed by the Oil Company
and other Oil Company affiliates directly related to the property's operations
are shown as direct operating expenses in the Statements.
 
3. COMMITMENTS AND CONTINGENCIES
 
  In the course of its business affairs and operations, the owners of the
properties are subject to possible loss contingencies arising from government
environmental, health and safety laws and regulations and third-party
litigation. There are no matters which, in the opinion of management of the
owners of the properties, will have a material adverse effect on the financial
results of the Property.
 
4. SUPPLEMENTARY FINANCIAL INFORMATION FOR OIL AND GAS PRODUCING ACTIVITIES
(UNAUDITED)
 
 Estimated Quantities of Proved Oil and Gas Reserves
 
  Reserve information presented below is based on the June 30, 1997 reserve
reports prepared by an independent petroleum engineer. Changes in reserve
estimates were derived by adjusting the June 30, 1997 quantities for
historical production and changes in prices.

  Proved reserves are estimated quantities of crude oil, natural gas and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions. Proved developed reserves
are those which are expected to be recovered through existing wells with
existing equipment and operating methods. Below are the net quantities of
proved reserves and proved developed reserves for the Property:

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS
 RELATING TO PROVED OIL AND GAS RESERVES
 
  The "Standardized Measure of Discounted Future Net Cash Flows Relating to
the Proved Oil and Gas Reserves" (Standardized Measure) has been prepared in
accordance with Statement of Financial Accounting Standards No. 69. The
Standardized Measure does not purport to present the fair market value of the
proved oil and gas reserves. This would require consideration of expected
future economic and operating conditions, which are not taken into account in
calculating the Standardized Measure.
 
  Under the Standardized Measure, 1996, 1995 and 1994 future cash inflows were
estimated by applying December 31, 1995, 1994 and 1993 prices, respectively,
adjusted for fixed and determinable escalations, to the estimated future
production of proved reserves. Future cash inflows for 1996, 1995 and 1994
were reduced by estimated future production and development costs based on
1996, 1995 and 1994 year-end costs, respectively, to determine pre-tax cash
inflows. Future net cash inflows were discounted using a 10% annual discount
rate to arrive at the Standardized Measure. No deduction has been made for
depletion, depreciation or any indirect costs such as general corporate
overhead or interest expense.

1. BASIS OF PRESENTATION
 
  The accompanying statements present revenue and certain expenses of 50 Penn
Place (the "Property"), an office building and retail center located in
Oklahoma City, Oklahoma whose operations are managed by Price Edward &
Company. Midland Red Oak Realty, Inc. ("Red Oak"), a subsidiary of Southwest
Royalties Holdings, Inc. ("SRH") as of September 30, 1997, and MBL Life
Assurance Corporation, owner of the Property, have executed a formal Purchase
and Sale Agreement allowing Red Oak to acquire the Property for approximately
$15 million.
 
  The accompanying statements have been prepared using the accrual basis of
accounting for the purpose of complying with the rules and regulations of the
Securities and Exchange Commission ("SEC") for inclusion in the registration
statement on Form S-4 of SRH and are presented in accordance with Rule 3.14 of
SEC Regulation S-X, which allows audited statements to be presented for only
the most recent period if the properties were purchased from an unrelated
party and if the registrant makes certain disclosures regarding factors
considered in purchasing the Property (see the Business section of the
Prospectus).
 
  The statements are not representative of the actual results of operations of
the Property for the year ended December 31, 1996, and the nine months ended
September 30, 1997, due to the exclusion of the following expenses, which may
not be comparable to the proposed future operations of the Property:
 
  .Depreciation and amortization
 
  .Corporate expenses of Property owner
 
  .Federal and state income taxes
 
  .Mortgage interest
 
  .Other costs not directly related to the proposed future operations of the
  Property
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Revenue Recognition
 
  Rent revenue is recognized on a straight-line basis over the term of the
individual leases.
 
 Use of Estimates
 
  Management of the Property has made a number of estimates and assumptions
relating to the reporting and disclosure of revenue and certain expenses
during the reporting period to prepare the statements of revenue and certain
expenses in conformity with generally accepted accounting principles. Actual
results could differ from those estimates.
 
3. RENT REVENUE
 
  Office and retail space is leased to tenants under various operating leases
with terms ranging from one to fifteen years. The leases generally provide for
minimum rent and reimbursement of real estate taxes, common area maintenance,
and certain other operating expenses. Certain leases also contain provisions
for percentage rent. Percentage rent earned for the year ended December 31,
1996, approximated $69,000.
 
  Future minimum rentals (base rent) to be received under noncancelable
operating leases in effect at December 31, 1996, are as follows:

for more than 10% of total revenue. Rent revenue earned from the tenant for the
year ended December 31, 1996, approximated $494,000.
 
5. COMMITMENTS
 
  At December 31, 1996, the Property had two noncancelable service agreements
which expire in March and July 1999. The future minimum payments under the
agreements at December 31, 1996, are as follows:

rules and regulations of the Securities and Exchange Commission ("SEC") for
inclusion in the registration statement on Form S-4 of SRH and are presented

disclosures regarding factors considered in purchasing the Property (see the
Business section of the Prospectus).
 
  The statement is not representative of the actual results of operations of
the property for the nine months ended September 30, 1996 due to the exclusion

operations of the Property:
 
  .Depreciation and amortization

  The statements are not representative of the actual results of operations of
the Property for the year ended December 31, 1996 and the nine months ended

                   FOR THE THREE MONTHS ENDED MARCH 31, 1997
 
1. BASIS OF PRESENTATION
 
  The accompanying statements of revenue and certain expenses relate to the
operations of Plaza Palomino (the "Property"), an office and retail building
located in Tucson, Arizona. The property was purchased by Midland Red Oak
Realty, Inc., a subsidiary of Southwest Royalties Holdings, Inc. ("SRH"), for
$7,025,000 in cash on April 7, 1997.
 
  The accompanying statements of revenue and certain expenses have been
prepared using the accrual basis of accounting for the purpose of complying
with the rules and regulations of the Securities and Exchange Commission
("SEC") for inclusion in the registration statement on Form S-4 of SRH and are
presented in accordance with Rule 3.14 of SEC Regulation S-X, which allows
audited statements to be presented for only the most recent period if the
properties were purchased from an unrelated party and if the registrant makes
certain disclosures regarding factors considered in purchasing the Property
(see the Business section of the Prospectus).
 
  The statements are not representative of the actual results of operations of
the property for the year ended December 31, 1996 and for the three months
ended March 31, 1997 due to the exclusion of the following expenses, which may
not be comparable to the proposed future operations of the Property:
 
  .Depreciation and amortization
 
  .Interest on mortgage which was not assumed by SRH
 
  .Federal and state income taxes
 
  .Other costs not directly related to the proposed future operations of the
  property
 
2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Revenue Recognition

 Use of Estimates
 
  Management of the Property has made a number of estimates and assumptions
relating to the reporting and disclosure of revenue and certain expenses
during the reporting period to prepare the statements of revenue and certain
expenses in conformity with generally accepted accounting principles. Actual

significant estimates made by management, as well as evaluating the overall
presentation of the statement. We believe that our audit provides a reasonable
basis for our opinion.
 
  The accompanying statement of revenue and certain expenses, as described in
Note 1, was prepared for the purpose of complying with the rules and
regulations of the Securities and Exchange Commission for inclusion in the

1. BASIS OF PRESENTATION
 
  The accompanying statements of revenue and certain expenses relates to the
operations of Crossroads Mall (the "Property"), a two-level enclosed shopping
center located in San Antonio, Texas. The property was purchased by Midland
Red Oak Realty ("Red Oak"), a subsidiary of Southwest Royalties Holdings, Inc.
("SRH") for $15,000,000 on October 23, 1997.
 
  The accompanying statements of revenue and certain expenses have been
prepared using the accrual basis of accounting for the purpose of complying
with the rules and regulations of the Securities and Exchange Commission
("SEC") for inclusion in the registration statement on Form S-4 of SRH and are
presented in accordance with Rule 3.14 of SEC Regulation S-X, which allows
audited statements to be presented for only the most recent period if the
properties were purchased from an unrelated party and if the registrant makes
certain disclosures regarding factors considered in purchasing the Property
(see the Business section of the Prospectus).
 
  The statements are not representative of the actual results of operations of
the Property for the nine months ended December 31, 1996 and the nine months
ended September 30, 1997, due to the exclusion of the following expenses,
which may not be comparable to the proposed future operations of the Property:
 
  . Depreciation and amortization
 
  . Interest on mortgage which will not be assumed by SRH
 
  . Federal income taxes
 
  . Other costs not directly related to the proposed future operations of the
    Property
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

                FOR THE NINE MONTHS ENDED DECEMBER 31, 1996 AND
           FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997 (UNAUDITED)
 
  Certain lessees have filed Chapter 11 bankruptcy. Accordingly, collection of
future rentals under existing lease agreements is not reasonably assured;
thus, future rentals related to such lessees are not included in the above
minimum rental amounts. Management of the Property believes that all rental
revenues recognized through September 30, 1997 are collectible. They will
continuously monitor the various bankruptcy situations and recognize rental
revenues only to the extent that collection is concluded to be reasonably
assured.
 
4. CONCENTRATION OF CREDIT RISK
 
  At December 31, 1996, five tenants aggregated accounted for approximately
42% of total revenue. Rent revenue earned from such tenants for the nine
months ended December 31, 1996 was as follows:

5. MANAGEMENT AGREEMENT
 
  The Property has a real estate management agreement with a realty service
company. This agreement can be terminated at the Property's option. A
management fee of 3 1/2 percent of gross collected revenues versus a minimum
fee of $15,000 is payable to the management company monthly. Total management
fees for the nine months ended December 31, 1996, were approximately $132,000.
