Securities and Exchange Commission. These securities may not be sold nor may
offers to buy be accepted prior to the time the registration statement becomes

                   SUBJECT TO COMPLETION, DATED JUNE 2, 1998.
    

PROSPECTUS

   
      [EXCO LOGO]          5,943,360 SHARES
    
                                  COMMON STOCK
                            ------------------------
   
         EXCO Resources, Inc. ("EXCO") is distributing to the holders of its
common stock, par value $.02 per share (the "Common Stock"), transferable rights
(the "Rights") to subscribe for and purchase an aggregate of 5,943,360 shares of
EXCO's Common Stock, for a price of $______ per share (the "Subscription
Price"). Each holder of Common Stock of record as of June __, 1998 is entitled
to receive ten Rights for each share of Common Stock held as of such date. One
Right entitles the holder to purchase one share of Common Stock. Each Right also
carries the right to subscribe at the Subscription Price for shares of Common
Stock that are not otherwise purchased pursuant to the exercise of Rights. The
Rights will be evidenced by transferable certificates (each, a "Subscription
Certificate"). The distribution of the Rights and sale of shares of Common Stock
are referred to herein as the "Rights Offering." There is no minimum number of
shares that must be subscribed for in the Rights Offering for it to be
completed. Ares Management, L.P. on behalf of Ares Leveraged Investment Fund,
L.P. (the "Standby Purchaser") has provided a standby commitment (the "Standby
Purchase Agreement") to purchase from EXCO a minimum of 1,000,000 shares of
Common Stock and a maximum of 2,000,000 shares of Common Stock not purchased
pursuant to the exercise of the Rights, also at a price of $______ per share.
The Standby Purchase Agreement would be exercised immediately following
expiration of the Rights Offering provided a minimum of 3,000,000 shares of
Common Stock are purchased pursuant to the Rights Offering, at least 250,000
shares of which must be purchased by Douglas H. Miller ("Mr. Miller"). See "The
Rights Offering."
    

   
         The Rights Offering, together with the Standby Purchase Agreement, are
intended to fund a pending acquisition transaction, to repay indebtedness of
EXCO and to increase EXCO's working capital. See "Use of Proceeds."
    

   
         The Rights will expire at 5:00 p.m., Dallas time, on __________, 1998,
unless extended by EXCO (such date and time, as it may be extended, the
"Expiration Date"), and thereafter will be void and of no effect. Shareholders
who do not exercise or sell their Rights prior to the Expiration Date will
relinquish the value inherent in the Rights. Accordingly, shareholders are
strongly urged to exercise or sell their Rights prior to the Expiration Date.
    

   
         On December 19, 1997, Mr. Miller purchased from certain holders of
413,423 shares of outstanding Common Stock at a price of $3.00 per share ($6.00
per share equivalent after adjusting for the one-for-two reverse stock split
(the "Reverse Stock Split") approved by shareholders on March 31, 1998) for an
aggregate purchase price of approximately $1.24 million. On December 31, 1997,
EXCO sold 100,000 shares of Common Stock each to T.W. Eubank ("Mr. Eubank") and
Earl E. Ellis ("Mr. Ellis") for a cash price of $3.00 per share ($6.00 per share
equivalent after adjusting for the Reverse Stock Split) for aggregate gross
proceeds of $600,000. The net proceeds were used to repay certain outstanding
accounts payable and to provide additional working capital to EXCO. On March 31,
1998, shareholders approved the expansion of membership on EXCO's Board. The
shareholders elected Mr. Miller, Mr. Eubank, J. Douglas Ramsey ("Dr. Ramsey"),
T. Boone Pickens ("Mr. Pickens"), Stephen F. Smith ("Mr. Smith"), Mr. Ellis and
J. Michael Muckleroy ("Mr. Muckleroy") to the Board. See "Recent Developments."
    

   
         The Prospectus also covers (i) the potential resale of Rights by
certain directors and executive officers of EXCO, including Messrs., Miller,
Eubank and Ellis and (ii) the reoffer and resale of Common Stock by the Standby
Purchaser and one additional purchaser of Rights. See "Selling Shareholders" and
"Plan of Distribution."
    

   
      The Common Stock is quoted on the OTC Bulletin Board (the "OTC") under the
symbol "EXCO." On May 29, 1998, the last reported sale price of the Common
Stock on the OTC was $6.50 per share as adjusted for the Reverse Stock Split.
It is anticipated that the Rights will trade on the OTC under the symbol "EXCO
RT" until the close of business on the last trading day preceding the Expiration
Date. EXCO intends to make application to list its Common Stock on the Nasdaq
National Market System following completion of the Rights Offering. There can be
no assurance that such application will be approved.

                               PROSPECTUS SUMMARY

   
         The following summary is qualified in its entirety by the more
detailed information and financial statements (including the notes thereto)
appearing elsewhere in this Prospectus or incorporated by reference in this
Prospectus. Unless the context otherwise requires, the term "EXCO" means EXCO
Resources, Inc. and its subsidiary taken as a whole. Quantities stated as
equivalent oil reserves are based on a factor of six thousand cubic feet of
natural gas per barrel of oil. Except as otherwise indicated herein, each
reference herein to "on a pro forma basis" shall mean that the results for the
stated period or other information has been adjusted to reflect the
consummation of the Maverick County Acquisition, the Jacobi-Johnson
Acquisition, the Dawson County Acquisition and the Merger Agreement (each as
defined herein). Unless otherwise stated herein, all references to shares of
Common Stock, for periods prior to March 31, 1998, do not take into account
EXCO's Reverse Stock Split (as defined herein) approved by shareholders on
March 31, 1998. Certain terms relating to the oil and natural gas business and
used herein are defined in the "Glossary of Selected Oil and Natural Gas Terms"
included elsewhere in this Prospectus.
    


                                   THE COMPANY
   
    EXCO is an independent oil and natural gas company that has been engaged in
the oil and natural gas business since 1955. EXCO's activities are currently
conducted primarily in Texas and Louisiana. Due to limited capital resources
and cash flow, in recent years EXCO's business activity has decreased. At
December 31, 1997, EXCO had 779,150 Boe of proved reserves, 93% of which were
natural gas, and owned leasehold interests in a total of 15,788 gross acres
(3,744 net acres) of oil and natural gas properties, 49% of gross acres (75%
net) which were developed acres. EXCO held interests in 47 gross (9.76 net)
wells at December 31, 1997. On a pro forma basis at December 31, 1997, EXCO had
an interest in 176 gross (49.0 net) wells and had estimated proved reserves of
1,965,500 Boe with an estimated SEC PV-10 of $10.2 million. Approximately 65%
of these reserves were classified as proved developed producing reserves. On a
pro forma basis at December 31, 1997, EXCO's proved reserves had an estimated
reserve life of 13.6 years and were 70% natural gas. EXCO currently serves as
operator of 66 wells. See "Business and Properties -- Oil and Natural Gas
Reserves" and "--Acreage." 
    

   
    On December 19, 1997, Mr. Miller acquired 413,423 (approximately 51%) of
EXCO's outstanding shares of Common Stock at $3.00 per share, from various
holders, including certain current and former officers and directors of EXCO.
At that time, three of EXCO's five directors resigned and Mr. Miller and Mr.
Eubank were elected to the Board of Directors. In addition, Mr. Miller was
elected Chairman of the Board and Chief Executive Officer and Mr. Eubank was
elected President, Treasurer and Chief Financial Officer. On December 31, 1997,
Mr. Eubank and Mr. Ellis each acquired from EXCO 100,000 shares of Common Stock
for $3.00 per share. Also, on December 31, 1997, Mr. Eubank resigned as Chief
Financial Officer and Dr. Ramsey was appointed Chief Financial Officer and Vice
President of EXCO. Mr. Miller was formerly Chairman of the Board and Chief
Executive Officer of Coda Energy, Inc. ("Coda"). Mr. Eubank was formerly
President and a director of Coda and Mr. Ellis was formerly a director of Coda.
Dr. Ramsey was formerly Financial Planning Manager of Coda. With the proceeds
of the Rights Offering and the credit facility arranged with NationsBank of
Texas, N.A. (the "Credit Facility"), the new management team has commenced an
aggressive acquisition, development and exploitation program. In executing this
strategy, EXCO will focus on producing properties with enhancement
opportunities from activities such as infill drilling, recompletions, repairs
and equipment changes. EXCO will seek properties it can operate, thus
maintaining the maximum control of enhancement activities. 
    

   
RECENT AND PENDING ACQUISITIONS

         Maverick County Acquisition. On February 11, 1998, EXCO acquired
certain properties from Osborne Oil Company and Gypsy Production Company and
certain other sellers (the "Maverick County Acquisition") in the Chittim/Barclay
Ranch Properties located in Maverick County, Texas (the "Maverick County
Properties"). As of December 31, 1997, the Maverick County Properties were
estimated to contain 415,975 Boe of proved reserves, 98% of which were natural
gas, and owned leasehold interests in a total of 3,744 gross acres (3,123 net
acres) of oil and natural gas properties, 9.6% of gross acres which were
developed acres. The aggregate purchase price for the Maverick County Properties
was $760,200. See "Recent Developments -- Maverick County Acquisition."

          Jacobi-Johnson Acquisition. On May 8, 1998, EXCO acquired all of the
outstanding common stock (the "Jacobi-Johnson Acquisition") of Jacobi-Johnson
Energy, Inc. ("Jacobi-Johnson"). Jacobi-Johnson owns oil and natural gas working
interests in Polk, Nacogdoches, Navarro, Smith and Wood Counties, Texas
(collectively, the "Jacobi-Johnson Properties"). The Jacobi-Johnson Properties
include 34 gross producing (14.3 net producing) wells with current net
production of approximately 59.4 Bbls of oil and 171,000 cubic feet of natural
gas per day. In addition to the producing wells, the Jacobi-Johnson Properties
include working interests in two saltwater disposal wells. As of December 31,
1997, the Jacobi-Johnson Properties are estimated to contain proved reserves of
234,985 Bbls of oil and 597,880 Mcf of natural gas. Approximately 100% of the
estimated proved reserves of the Jacobi-Johnson Properties are classified as
developed. The aggregate purchase price paid for the stock was $1,476,451,
subject to post-closing adjustments. See "Recent Developments -- Jacobi --
Johnson Acquisition."
           
         Gladstone Merger. EXCO entered into an Agreement and Plan of Merger
(the "Merger Agreement") on May 1, 1998 with Gladstone Resources, Inc.
("Gladstone"). Gladstone is a Dallas, Texas based oil and natural gas
production company with properties located in Kent, Stonewall, Schleicher,
Pecos and Madison Counties, Texas, and San Juan County, New Mexico. Under terms

CONTROL OF EXCO

   
         Upon purchasing the shares of EXCO's Common Stock on December 19, 1997,
Mr. Miller held approximately 51% of EXCO's outstanding Common Stock. On that
date, three of EXCO's five directors resigned and Mr. Miller was nominated and
appointed to the Board. Also, on December 19, 1997, Mr. Miller nominated Mr.
Eubank to the Board and Mr. Eubank was appointed a director. David N. Fitzgerald
and Charles W. Gleeson, then-existing directors, remained on the Board until
March 31, 1998, when the shareholders of EXCO elected Messrs. Miller, Eubank,
Ramsey, Pickens, Smith, Ellis and Muckleroy.
    

   
         On December 31, 1997, EXCO sold 100,000 shares of its Common Stock to
each of Messrs. Eubank and Ellis (with each now holding approximately 10% of
EXCO's outstanding Common Stock). Mr. Miller currently holds approximately 41%
of the outstanding Common Stock. Messrs. Ellis, Eubank and Miller intend to
exercise an indeterminate number of their Rights pursuant to the Rights
Offering. Further, Messrs. Ellis, Eubank and Miller may assign an indeterminate
number of their Rights to other buyers, including transferring Rights to the
Standby Purchaser. See "Recent Developments -- Change of Control."
    

CREDIT FACILITY

         On February 11, 1998, EXCO entered into the Credit Facility with
NationsBank of Texas, N.A. The Credit Facility provides for borrowings not to
exceed $50 million, subject to borrowing base limitations.

   
         The Credit Facility consists of a regular revolver, which at May 15,
1998, had a borrowing base of $3.5 million. As of May 15, 1998, approximately
$1,325,000 was available to be borrowed under the Credit Facility. All
borrowings under the Credit Facility are secured by a first lien deed of trust
providing a security interest in tangible and intangible assets representing at
least 90% of the assessed present value of EXCO's oil and natural gas
properties. See "Description of Credit Facility."
    

BUSINESS STRATEGY

         Following completion of the Rights Offering, EXCO intends to build
itself as a leading independent oil and natural gas exploitation and production
company by implementing the following business strategies:

         o        Growth. Achieve asset, revenue and cash flow growth as a
                  result of the acquisition and further development of other
                  producing oil and natural gas properties. EXCO believes there
                  are numerous opportunities to acquire additional energy assets
                  and to enhance the value of such assets through improved
                  operating practices and by aggressively developing reserve
                  potential.

   
         o        Acquire and Enhance Producing Oil and Natural Gas Properties.
                  Take advantage of opportunities that currently exist in the
                  United States to acquire producing oil and natural gas
                  properties. EXCO plans to continue to focus its acquisition
                  activities onshore in Texas, New Mexico, Oklahoma and
                  Louisiana in order to complement its existing properties and
                  operations; however, EXCO plans to review potential
                  acquisitions in other regions of the United States if they
                  represent a significant concentration of energy-related
                  assets.

<PAGE>   8


   
         o        Emphasize Exploitation and Development Activities. Exploit its
                  existing oil and natural gas properties and to conduct
                  development evaluation and drilling on its existing and future
                  oil and natural gas properties. EXCO intends to concentrate on
                  enhancement opportunities from activities such as infill
                  drilling, recompletions, repairs and equipment changes. EXCO
                  may participate, from time to time, in a limited number of
                  exploratory wells.
    

         o        Corporate Efficiencies. Maximize corporate efficiencies
                  through the development and operation of a larger asset base
                  with the potential to limit increases in overhead in the
                  future.

         o        Capital Management. Maintain financial strength and
                  flexibility through effective management of debt and equity.

   
         o        Technology. Increase its exploitation efforts, focusing on
                  established geological trends where EXCO can employ
                  geological, geophysical and engineering expertise. EXCO is
                  considering the application of 3-D seismic and advanced
                  drilling technologies where cost-effective and appropriate.

                               THE RIGHTS OFFERING

   
         The Rights Offering is an integral part of EXCO's growth strategy. The
Rights Offering is intended to recapitalize EXCO through the issuance of up to
approximately $____ million in Common Stock. The net proceeds of the Rights
Offering along with amounts borrowed under the Credit Facility will be used to
fund the expansion and diversification of EXCO's operations through the
acquisition of oil and natural gas producing properties and the further
development and exploitation of those properties. EXCO will issue and sell up to
an aggregate of approximately $____ million of Common Stock to investors who
subscribe to purchase shares of Common Stock in the Rights Offering and through
the exercise of the Standby Purchase Agreement, if necessary. The Rights
Offering will permit holders of rights to purchase shares of Common Stock at
$______ per share. The price was determined by the Board of Directors after
considering such factors as the price paid by Messrs. Miller, Eubank and Ellis
for the purchase of shares in December 1997, the current trading price for the
Common Stock, future prospects of EXCO,the industry in general and EXCO's
position in the industry, market valuations of the Company of the securities of
companies engaged in similar activities, the quality of the management team, and
negotiations with the Standby Purchaser. See "The Rights Offering."

EFFECTS OF THE RIGHTS OFFERING

         The net proceeds from the Rights Offering will enhance EXCO's ability
to compete in the oil and natural gas industry by providing significant equity
capital to EXCO and improving its ability to attract additional capital. The
Rights Offering will allow EXCO to build its equity capital position which EXCO
believes it can leverage under its Credit Facility and to arrange other debt and
equity offerings. A portion of the net proceeds will be used to repay
outstanding indebtedness incurred under the Credit Facility in connection with
the Maverick County Acquisition, the Jacobi-Johnson Acquisition and the Dawson
County Acquisition. Management believes all of these actions will enhance 
EXCO's ability to pursue additional acquisition and development opportunities 
and to carry out its business strategy.

                                        the Oversubscription Privilege (if
                                        needed) and the Standby Commitment (if
                                        needed). See "The Rights Offering -- The
                                        Rights."

                                        thereof to receive, upon payment of the

                                        Subscription Privilege."

Oversubscription Privilege..........    Each holder of Rights who exercises in
                                        full such holder's Basic Subscription
                                        Privilege may also subscribe at the
                                        Subscription Price for additional Rights
                                        to acquire additional shares of Common
                                        Stock available as a result of
                                        unexercised Rights, if any (the
                                        "Oversubscription Privilege"). In no
                                        event, however, may the holder of Rights
                                        oversubscribe for more than 100% of the
                                        shares purchased by the holder in the
                                        Basic Subscription Privilege. If the
                                        number of shares available, taking into
                                        account the aforementioned restrictions,
                                        are not sufficient to satisfy the
                                        oversubscriptions, the available shares
                                        will be allocated pro rata (subject to
                                        elimination of fractional shares) among
                                        the holders of Rights who exercise the
                                        Oversubscription Privilege, in
                                        proportion, not to the number of shares
                                        requested pursuant to the
                                        Oversubscription Privilege, but to the
                                        number of shares each beneficial holder
                                        has purchased pursuant to the Basic
                                        Subscription Privilege; provided,
                                        however, that if such pro rata
                                        allocation results in any holder being
                                        allocated a greater number of shares
                                        than such holder subscribed for pursuant
                                        to the exercise of such holder's
                                        oversubscription Privilege, then such
                                        holder will be allocated only such
                                        number of shares as such holder
                                        subscribed for and the remaining shares
                                        will be allocated among all other
                                        holders exercising the Oversubscription
                                        Privilege. See "The Rights Offering--
                                        Subscription Privileges--
                                        Oversubscription Privilege."

                                        pursuant to the exercise of Rights

                                        and the Oversubscription Privilege. The
                                        Standby Purchaser will purchase a 
                                        minimum of 1,000,000 shares and a

                                        the Standby Purchaser and at least

                                        Mr. Miller. In addition, the Standby
                                        Purchaser may acquire Rights from

                                        procedures), together with payment of
                                        the Subscription Price for each share of
                                        Common Stock subscribed for pursuant to
                                        the Basic Subscription Privilege and the

                                        Continental Stock Transfer & Trust
                                        Company, as subscription agent (the
                                        "Subscription Agent"), on or prior to
                                        the Expiration Date. If forwarding
                                        Subscription Certificates by mail, it is
                                        recommended that insured, registered
                                        mail be used. No interest will be paid
                                        on funds delivered in payment of the
                                        Subscription Price. The Instructions as
                                        to use of EXCO Resources, Inc.
                                        Subscription Certificates (the
                                        "Instructions") accompanying the
                                        Subscription Certificates should be read
                                        carefully and followed in detail. See
                                        "The Rights Offering-- Exercise of
                                        Rights."
    

NO REVOCATION.......................    ONCE A HOLDER OF RIGHTS HAS EXERCISED
                                        THE BASIC SUBSCRIPTION PRIVILEGE OR THE
                                        OVERSUBSCRIPTION PRIVILEGE, SUCH
                                        EXERCISE MAY NOT BE REVOKED. SEE "THE
                                        RIGHTS OFFERING -- NO REVOCATION."

Transferability of Rights...........    The Rights are transferable, and it is
                                        expected that they will trade on the OTC
                                        until the close of business on the last
                                        OTC trading day prior to the Expiration
                                        Date. There can be no assurance,
                                        however, that a market for the Rights
                                        will develop or, if a market develops,
                                        that the market will remain available
                                        throughout the period during which
                                        Rights may be exercised, or as to the
                                        price at which the Rights will trade.
                                        See "The Rights Offering-- Method of
                                        Transferring Rights."

   
Certain Federal Income Tax
  Considerations....................    For United States federal income tax
                                        purposes, Rights holders generally
                                        should not recognize taxable income in
                                        connection with the issuance to them or
                                        exercise by them of Rights. Rights
                                        holders may incur gain or loss upon the
                                        sale of the Rights or the shares of
                                        Common Stock acquired upon exercise of
                                        the Rights or upon the receipt of
                                        dividends. See "Material Federal Income
                                        Tax Considerations."

OTC Symbols.........................    The Common Stock is traded on the OTC
                                        under the symbol "EXCO." It is
                                        anticipated that the Rights and the
                                        Common Stock will trade on the OTC under
                                        the symbol "EXCO RT."

Common Stock........................    The terms of the Common Stock are
                                        described under "Description of Capital
                                        Stock."

Listing.............................    EXCO intends to make application to list
                                        its Common Stock on the Nasdaq National
                                        Market System following completion of
                                        the Rights Offering. There can be no
                                        assurance the Common Stock will be
                                        accepted for listing.


   
Resales by Affiliates...............    Certain directors and officers of EXCO
                                        who are also shareholders of EXCO (the
                                        "Selling Rightsholders") including
                                        Messrs. Miller, Eubank and Ellis, will
                                        be receiving Rights on the same terms as
                                        all other shareholders. This Prospectus
                                        also covers the resale, if any, of
                                        Rights by such Selling Rightsholders.
                                        EXCO will not receive any of the
                                        proceeds of such sales of Rights by a
                                        Selling Rightsholder. This Prospectus
                                        also covers resales of shares of Common
                                        Stock that may be acquired upon exercise
                                        of rights by one potential acquiror of
                                        Rights. See "Selling Shareholders" and
                                        "Plan of Distribution."

       EXCO's method of accounting for oil and natural gas operations to the
       full cost method of accounting. See Note 2 to EXCO's Financial
       Statements. As a result of the change in the accounting method, net
       income has been increased by $44,000 ($0.15 per share) for the year ended
       March 31, 1994; the net loss for the year ended March 31, 1995, the nine
       month period ended December 31, 1995 and the year ended December 31,
       1996, has been decreased $40,000 ($0.12 per share), $184,000 ($0.54 per
       share) and $3,000 ($0.01 per share), respectively.
(2)    The $303,000 expense in fiscal 1996 represents the legal, accounting and
       other expenses associated with the attempted acquisition by EXCO of
       Taurus Energy Corp.
   
(3)    Per share data has been restated to reflect the one-for-five reverse
       stock split effective July 19, 1996 and the Reverse Stock Split effective
       March 31, 1998. The adoption of Financial Accounting Standards Board No.
       128, Earnings per Share, did not have a material impact on net income
       (loss) per share amounts reported herein.
    
   
(4)    EXCO has not paid any dividends during any of the periods presented.

                                  RISK FACTORS

         Holders of Rights should consider carefully the following factors
relating to the business of EXCO and the Rights Offering, together with the
information and financial data set forth elsewhere in this Prospectus, prior to
making an investment decision.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

         This Prospectus includes "forward-looking statements" within the
meaning of Section 27A of the Securities Act of 1933, as amended (the
"Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), which can be identified by the use of
forward-looking terminology such as, "may," "believe," "expect," "intend,"
"anticipate," "estimate" or "continue" or the negative thereof or other
variations thereon or comparable terminology. All statements other than
statements of historical fact included in this Prospectus, including without
limitation, the statements under "Prospectus Summary," "Risk Factors," "Pro
Forma Combined Condensed Financial Statements," "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources," "Business and Properties -- Business Strategy," "Business
and Properties -- Oil and Natural Gas Reserves" and "Certain Federal Income Tax
Considerations -- Tax Consequences to Holders of Rights" located elsewhere
herein regarding EXCO's financial position and liquidity, the volume or
discounted present value of its oil and natural gas reserves, its ability to
service its indebtedness, its strategic plans including its ability to locate
and complete acquisitions of oil and natural gas assets, and other matters, are
forward-looking statements. Although EXCO 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. Important
factors with respect to any such forward-looking statements, including certain
risks and uncertainties that could cause actual results to differ materially
from EXCO's expectations ("Cautionary Statements") are disclosed in this
Prospectus, including, without limitation, in conjunction with the
forward-looking statements included in this Prospectus. Important factors that
could cause actual results to differ materially from those in the
forward-looking statements herein include, but are not limited to, the timing
and extent of changes in commodity prices for oil and natural gas, the need to
develop and replace reserves, environmental risks, drilling and operating risks,
risks related to exploitation and development, uncertainties about the estimates
of reserves, competition, government regulation and the ability of EXCO to meet
its stated business goals. All subsequent written and oral forward-looking
statements attributable to EXCO or persons acting on its behalf are expressly
qualified in their entirety by the Cautionary Statements.

FINANCIAL RISKS

         FUTURE DEBT SERVICE

         EXCO has arranged the Credit Facility to provide an additional source
of capital to finance EXCO's acquisition, development and exploitation strategy.
EXCO's level of indebtedness in the future could have certain effects on its
future operations, including that (i) a substantial portion of EXCO's cash flow
from operations could be dedicated to the payment of interest and principal on
its indebtedness and will not be available for other purposes, (ii) the
covenants contained in the Credit Facility require EXCO to meet certain
financial tests and other restrictions, will limit its ability to borrow
additional funds, to grant liens and to dispose of assets and will affect EXCO's
flexibility in planning for and reacting to changes in its business, including
possible acquisition activities, and (iii) EXCO's ability to obtain additional
financing in the future for working capital, capital expenditures, acquisitions,
general corporate purposes or other purposes may be impaired. The pledge of
substantially all of EXCO's assets as collateral for the Credit Facility will
for the foreseeable future make it difficult for EXCO to obtain financing on an
unsecured basis or to obtain secured financing other than certain "purchase
money" indebtedness collateralized by the acquired assets.

         EXCO's ability to meet any future debt service obligations will be
dependent upon EXCO's future performance, which will be subject to oil and
natural gas prices, EXCO's level of production, general economic conditions and
to financial, business and other factors affecting the operations of EXCO, many
of which are beyond its control. There can be no assurance that EXCO's future
performance will not be adversely affected by such changes in oil and natural
gas prices and/or production nor by such economic conditions and/or financial,
business and other factors. In addition, there can be no assurance that EXCO's
business will generate sufficient cash flow from operations or that future bank
credit will be available in an amount sufficient to enable EXCO to service its
indebtedness or make necessary expenditures. In such event, EXCO would be
required to obtain such financing from

                                       14

<PAGE>   17


the sale of equity securities or other debt financing. There can be no assurance
that any such financing will be available on terms acceptable to EXCO. Should
sufficient capital not be available, EXCO may not be able to continue to
implement its business strategy. See "Management's Discussion and Analysis of
Financial Position and Results of Operations -- Liquidity and Capital
Resources."

         HISTORY OF LOSSES

   
         EXCO had net losses of $160,000, $326,000 and $205,000, for the nine
months ended December 31, 1995 and the years ended December 31, 1996 and 1997,
respectively. EXCO had a net loss of $194,000 for the first three months ended
March 31, 1998 due to a $133,000 increase in general and administrative costs.
This increase reflects EXCO's increased staffing and new focus on reserve
acquisitions. There is no assurance that EXCO will consummate any acquisitions
in the future and, to the extent that natural gas and crude oil prices are low,
such losses may be substantial. See "-- Business and Industry Risks -- Effects
of Changing Prices" and "Pro Forma Combined Condensed Financial Statements." 
    

RIGHTS OFFERING RISKS

         MARKET CONSIDERATIONS

   
         The Subscription Price was determined by the Board of EXCO and may not
reflect the actual or fair value of EXCO or the Common Stock. The price was
determined after considering such factors as the price paid by Messrs. Miller,
Eubank and Ellis for the purchase of their shares in December 1997 after taking
into account the Reverse Stock Split, the current trading price for the Common
Stock, future prospects of EXCO, the industry in general and EXCO's position in
the industry, market valuations of the securities of companies engaged in
similar activities, the quality of the management team and negotiations with the
Standby Purchaser. At the time the Subscription Price for the Rights Offering
was determined, such price represented a ___% discount to the market price for
EXCO's Common Stock. There is currently no public market for the Rights.
Although the Rights will be listed for trading on the OTC, there can be no
assurance that an active public market will develop or be sustained for the
Rights, that the market price of the Common Stock will not decline during the
subscription period or that, following the issuance and exercise of the Rights,
a subscribing Rights holder will be able to sell shares of Common Stock
purchased in the Rights Offering at a price equal to or greater than the
Subscription Price. The market price of the Common Stock could be subject to
significant fluctuations in response to EXCO's operating results and other
factors, including the size of the public float of the Common Stock (which will
depend in part on the percentage of the Rights that are exercised pursuant to
the Rights Offering).
    

         The effect of the discount on the market price for the Rights may
increase the trading values for the Rights relative to what those trading values
might be if such discount were not present. However, due to the inherent value
of the Rights, the market price for EXCO's Common Stock may decrease by an
amount that approximates the value of the Rights when the Rights are distributed
and begin to trade as a separate security.

         IRREVOCABILITY OF SUBSCRIPTIONS

         The election to exercise Rights is irrevocable. Until certificates
representing shares of Common Stock are delivered, subscribing Rights holders
may not be able to sell such shares. Certificates representing shares of Common
Stock purchased in the Rights Offering will be delivered by mail as soon as
practicable following the Expiration Date. No interest will be paid to Rights
holders on funds delivered to the Subscription Agent pursuant to the exercise of
Rights pending delivery of such certificates and return of any excess funds not
applied to the purchase of shares.

         NO MINIMUM SUBSCRIPTION

   
         There is no minimum number of shares that must be subscribed for in the
Rights Offering. The Standby Purchase Agreement is conditioned upon Rights for
3,000,000 shares being exercised. However, even if this condition is not met,
it is EXCO's intention to consummate the Rights Offering and issue the number
of shares of Common Stock actually subscribed for, without performance of the
Standby Purchase Agreement. To the extent that this Rights Offering is not fully
subscribed for, EXCO would receive a smaller sum of net proceeds and its growth
strategy may be slowed.
    

         CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

   
         Haynes and Boone, LLP has rendered an opinion that the holders of 
Common Stock should recognize no income or gain for federal income tax purposes
upon the receipt, exercise or lapse of the Rights, although this matter is not
free from doubt. Nevertheless, the federal income tax treatment of the
distribution of Rights to holders of Common Stock and any subsequent exercise or
lapse of such Rights is subject to some uncertainty with respect to the
characterization of the distribution of the Rights under the Internal Revenue
Code of 1986, as amended. See "Certain Federal Income Tax Considerations" for a
more detailed discussion of the federal income tax consequences resulting from
the purchase, ownership and disposition of Rights.

BUSINESS AND INDUSTRY RISKS

         NEED FOR ADDITIONAL FINANCING FOR GROWTH

         The growth of EXCO's business will require substantial capital on a
continuing basis. There is no assurance that any such required additional funds
would be available on satisfactory terms and conditions, if at all. There is
also no assurance that EXCO will not pursue, from time to time, opportunities to
acquire oil and natural gas properties and businesses that may utilize the
capital currently expected to be available for its present operations. The
amount and timing of EXCO's future capital requirements, if any, will depend
upon a number of factors, including drilling costs, transportation costs,
equipment costs, marketing expenses, staffing levels and competitive conditions,
and any purchases or dispositions of assets, many of which are not within EXCO's
control. Failure to obtain any required additional financing could materially
adversely affect the growth, cash flow and earnings of EXCO. In addition, EXCO's
pursuit of additional capital could result in the incurrence of additional debt
or potentially dilutive issuances of additional equity securities. See
"Management's Discussion and Analysis of Financial Position on Results of
Operations -- Liquidity and Capital Resources."

         CONCENTRATION OF PRODUCTION

   
         Four properties which currently include 2 wells account for 75% of
EXCO's SEC PV-10 value based on proved reserves (including proved undeveloped
reserves) at December 31, 1997. On a pro forma basis, 44 properties which
currently include 52 wells account for 75% of EXCO's SEC PV-10 value based on
proved reserves (including proved undeveloped reserves) at December 31, 1997.
Accordingly, to the extent that EXCO experiences any operating difficulties in
connection with such wells or that the estimated proved reserves attributable
thereto are less than those that are currently estimated to exist or to the
extent EXCO is unable to fully develop proved reserves currently classified as
proved undeveloped reserves, EXCO could be adversely affected.
    

         GEOGRAPHIC RESTRICTIONS

         Pursuant to the non-competition provisions of Mr. Miller's employment
agreement with Coda, Mr. Miller, and as a result EXCO, is prohibited for a
period of one year beginning November 26, 1997 from acquiring or seeking to
acquire any rights or interest in any of sixteen properties in which Coda has an
existing interest or which it was studying at November 26, 1997. This
restriction also extends to two oil and natural gas companies. Some of these
locations are in areas in which EXCO might have an interest and generally
represent the types of properties EXCO would be interested in acquiring. The
non-competition restrictions may adversely effect, at least in the short term,
EXCO's ability to execute its growth strategy.

         INABILITY TO DEVELOP ADDITIONAL RESERVES

         EXCO's future success as an oil and natural gas producer, as is
generally the case in the industry, depends upon its ability to find, develop
and acquire additional oil and natural gas reserves that are economically
recoverable. Except to the extent that EXCO conducts successful development
activities or acquires properties containing proved reserves, EXCO's proved
reserves will generally decline as reserves are produced. There can be no
assurance that EXCO will be able to locate additional reserves or that EXCO will
drill economically productive wells or acquire properties containing proved
reserves. See "Business and Properties -- Acreage" and "-- Drilling Activities."

         ACQUISITION RISKS

         EXCO's business strategy includes focused acquisitions of producing oil
and natural gas properties. Any such future acquisitions will require an
assessment of the recoverable reserves, future oil and natural gas prices,
operating costs, potential environmental and other liabilities and other similar
factors. It generally is not feasible to review in detail every individual
property involved in an acquisition. Ordinarily, review efforts are focused on
the higher-valued properties. However, even a detailed review of all properties
and records may not reveal existing or potential problems; nor will it permit
EXCO to become sufficiently familiar with the properties to assess fully their
deficiencies and capabilities. Inspections are not always performed on every
well, and potential problems, such as mechanical integrity of equipment and
environmental conditions that may require significant remedial expenditures, are
not necessarily observable even when an inspection is undertaken. Even if
problems are identified, the seller may be unwilling or unable to provide
effective contractual protection against all or part of such problems. There can
be no assurance that oil and natural gas properties acquired by EXCO will be
successfully integrated into EXCO's operations or will achieve desired
profitability objectives.

                                       16

<PAGE>   19


         DRILLING RISKS

         EXCO's drilling involves numerous risks, including the risk that no
commercially productive natural gas or oil reservoirs will be encountered. EXCO
must incur significant expenditures for the identification and acquisition of
properties and for the drilling and completion of wells. 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, weather conditions and shortages or delays in
the delivery of equipment. In addition, any use by EXCO of 3-dimensional seismic
and other advanced technology requires greater pre-drilling expenditures than
traditional drilling strategies. There can be no assurance as to the success of
EXCO's future drilling activities.

         UNCERTAINTY OF ESTIMATES OF OIL AND NATURAL GAS RESERVES

         Numerous uncertainties are inherent in estimating quantities of proved
oil and natural gas reserves, including many factors beyond the control of EXCO.
This Prospectus contains an estimate of EXCO's proved oil and natural gas
reserves and the estimated future net cash flows and revenue therefrom based
upon reports of EXCO's independent petroleum engineers. Such reports rely upon
various assumptions, including assumptions required by the Commission, as to
constant oil and natural gas prices, drilling and operating expenses, capital
expenditures, taxes and availability of funds and such reports should not be
construed as the current market value of the estimated proved reserves. The
process of estimating oil and natural gas reserves is complex, requiring
significant decisions and assumptions in the evaluation of available geological,
engineering and economic data for each reservoir. As a result, such estimates
are inherently an imprecise evaluation of reserve quantities and the future net
revenue therefrom. Actual future production, revenue, taxes, development
expenditures, operating expenses and quantities of recoverable oil and natural
gas reserves may vary substantially from those assumed in the estimate. Any
significant variance in these assumptions could materially affect the estimated
quantity and value of reserves set forth in this Prospectus. In addition, EXCO's
reserves may be subject to downward or upward revision, based upon production
history, results of future exploitation and development, prevailing oil and
natural gas prices and other factors. See "Business and Properties -- Oil and
Natural Gas Reserves."

         GEOGRAPHIC CONCENTRATION OF OPERATIONS

         Virtually all of EXCO's current operations are located in Texas and
Louisiana. Because of this concentration, any regional events that increase
costs or competition, reduce availability of equipment or supplies, reduce
demand or limit production will impact EXCO more adversely than if EXCO was
geographically diversified.

         CERTAIN INDUSTRY AND MARKETING RISKS

         EXCO's operations are subject to the risks and uncertainties associated
with drilling for, producing and transporting of oil and natural gas. EXCO's
future ability to market its natural gas and oil production will depend upon the
availability and capacity of natural gas gathering systems and pipelines and
other transportation facilities. Federal and state regulation of oil and natural
gas production and transportation, general economic conditions, changes in
supply and in demand all could materially adversely affect EXCO's ability to
market its oil and natural gas production. See "Business and Properties --
Products, Markets and Revenues" and "-- Regulation."

         EFFECTS OF CHANGING PRICES

   
         The future financial condition and results of operations of EXCO depend
upon the prices it receives for its oil, natural gas and the costs of acquiring,
developing and producing oil and natural gas. Oil and natural gas prices have
historically been volatile and are subject to fluctuations in response to
changes in supply, market uncertainty and a variety of additional factors that
are also beyond EXCO's control. These factors include, without limitation, the
level of domestic production, the availability of imported oil and natural gas,
actions taken by foreign oil and natural gas producing nations, the availability
of transportation systems with adequate capacity, the availability of
competitive fuels, fluctuating and seasonal demand for natural gas, conservation
and the extent of governmental regulation of production, weather, foreign and
domestic government relations, the price of domestic and imported oil and
natural gas, and the overall economic environment. A substantial or extended
decline in oil and/or natural gas prices could have a material adverse effect on
EXCO's estimated value of its natural gas and oil reserves, and on its financial
position, results of operations and access to capital. EXCO does not currently
use any financial
    

                                       17

<PAGE>   20


   
products to hedge commodity price volatility risk, although it may use such
financial products in the future. EXCO does not currently have a hedging policy.
EXCO's ability to maintain or increase its borrowing capacity, to repay current
or future indebtedness and to obtain additional capital on attractive terms is
substantially dependent upon oil and natural gas prices. See "Business and
Properties -- Products, Markets and Revenues."
    

         EXCO 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 unit-of-production method based on
the ratio of current production to total proved oil and natural gas reserves. To
the extent that such capitalized costs (net of accumulated depreciation,
depletion and amortization) less deferred taxes exceed the SEC PV-10 of
estimated future net cash flow from proved reserves of oil and natural gas, and
the lower of cost or fair value of unproved properties after income tax effects,
such excess costs are charged against earnings. 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.

         OPERATING HAZARDS AND UNINSURED RISKS

         EXCO's operations are subject to the risks inherent in the oil and
natural gas industry, including the risks of fire, explosions, blow-outs, pipe
failure, abnormally pressured formations and environmental accidents such as oil
spills, gas leaks, ruptures or discharges of toxic gases, brine or well fluids
into the environment (including groundwater contamination). The occurrence of
any of these risks could result in substantial losses to EXCO due to injury or
loss of life, severe damage to or destruction of property, natural resources and
equipment, pollution or other environmental damage, clean-up responsibilities,
regulatory investigation and penalties and suspension of operations. In
accordance with customary industry practice, EXCO maintains insurance against
some, but not all, of the risks described above. There can be no assurance that
any insurance maintained by EXCO will be adequate to cover any such losses or
liabilities. Further, EXCO cannot predict the continued availability of
insurance, or availability at commercially acceptable premium levels. EXCO does
not carry business interruption insurance. Losses and liabilities arising from
uninsured or under-insured events could have a material adverse effect on the
financial condition and operations of EXCO. From time to time, due primarily to
contract terms, pipeline interruptions or weather conditions, the producing
wells in which EXCO owns an interest have been subject to production
curtailments. The curtailments range from production being partially restricted
to wells being completely shut-in. The duration of curtailments varies from a
few days to several months. In most cases EXCO is provided only limited notice
as to when production will be curtailed and the duration of such curtailments.
EXCO is not currently experiencing any material curtailment on its production.

         SUBSTANTIAL COMPETITION

         The oil and natural gas industry is highly competitive and there are
many other companies engaged in the oil and natural gas business. EXCO is likely
to encounter substantial competition from major oil companies, other independent
oil and natural gas concerns and individual producers and operators in acquiring
oil and natural gas properties suitable for exploitation and development. Many
of the companies with which EXCO competes have substantially greater financial,
technical and other resources and may have greater experience in the oil and
natural gas business than EXCO. Therefore, competitors may be able to pay more
for desirable leases and to evaluate, bid for and purchase a greater number of
properties or prospects than the financial or personnel resources of EXCO will
permit. See "Business and Properties -- Competition."

         MARKET FOR COMMON STOCK

         EXCO cannot ensure that an active trading market for the Common Stock
on the OTC or any other market will develop or be sustained subsequent to the
offering made hereby. After completion of the offering made hereby, the market
for the Common Stock may be influenced by many factors, including the depth and
liquidity of the market for the Common Stock, investor perceptions of EXCO and
general economic and other similar conditions. EXCO intends to make application
to list its Common Stock on the Nasdaq National Market System following
completion of the Rights Offering. There can be no assurance the Common Stock
will be approved for listing.

         VOLATILITY OF STOCK PRICE

         The market price for shares of the Common Stock has varied
significantly and may be volatile depending on news announcements or changes in
general market conditions. In particular, news announcements, quarterly results
of operations, competitive developments, litigation or governmental regulatory
action impacting EXCO may adversely affect the Common Stock price. In addition,
because the number of shares of Common Stock held by the public is relatively
small, the sale of a substantial number of shares of the Common Stock in a short
period of time could adversely affect the market price of the Common Stock. See
"Price Range of Common Stock and Dividend Policy."

         DIVIDEND POLICY

         EXCO has never paid cash dividends on its Common Stock and does not
anticipate paying cash dividends on its Common Stock in the foreseeable future.
The Common Stock is not a suitable investment for persons requiring current
income. See "Price Range of Common Stock and Dividend Policy."

         ANTI-TAKEOVER EFFECT OF ARTICLES OF INCORPORATION AND POSSIBLE
         ISSUANCES OF PREFERRED STOCK

   
         Certain provisions of the Articles of Incorporation may delay, defer or
prevent a tender offer or takeover attempt that a shareholder might consider to
be in such shareholder's best interest, including attempts that might result in
a premium over the market price for the stock held by shareholders. The Articles
of Incorporation permit the Board to issue up to 10,000,000 shares of preferred
stock and to establish by resolution one or more series of preferred stock and
to establish the powers, designations, preferences and relative, participating,
optional or other special rights of each series of preferred stock. The
preferred stock could be issued on terms that are unfavorable to the holders of
Common Stock, including the grant of superior voting rights, the grant of
preferences in favor of preferred shareholders in the payment of dividends and
upon liquidation of EXCO and the designation of conversion rights that entitle
holders of preferred stock to convert their shares into Common Stock on terms
that are dilutive. The issuance of preferred stock could make a takeover or
change in control of EXCO more difficult. EXCO however does not intend to use
the provisions of the Articles of Incorporation to delay, defer or prevent a
tender offer or takeover attempt. Article 13 of the Texas Business Corporation
Act  also provides certain protections to shareholders of publicly-held Texas
corporations such as EXCO from certain takeover attempts. See "Description of
Capital Stock."
    


         DEPENDENCE UPON KEY PERSONNEL

   
         EXCO is substantially dependent upon two key individuals within its
management, Mr. Miller and Mr. Eubank. The loss of the services of either one of
these individuals could have a material adverse impact upon EXCO. EXCO does not
have key man insurance on either of these two individuals. See "Management."
    

GOVERNMENTAL REGULATION

         GENERAL

         EXCO's operations are affected from time to time in varying degrees by
political developments and federal and state laws and regulations. In
particular, oil and natural gas production, operations and economics are or have
been affected by price controls, taxes and other laws relating to the oil and
natural gas industry, by changes in such laws and by changes in administrative
regulations. EXCO cannot predict how existing laws and regulations may be
interpreted by enforcement agencies or court rulings, whether additional laws
and regulations will be adopted, or the effect such changes may have on its
business or financial condition. 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, unitization and pooling of properties, and taxation. There can
be no assurance that new laws or regulations, or modifications of or new
interpretations of existing laws and regulations, will not increase
substantially the cost of compliance or otherwise adversely affect EXCO's oil
and natural gas operations and financial condition or that material indemnity
claims will not arise against EXCO with respect to properties acquired by or
from EXCO. See "Business and Properties -- Regulation."

<PAGE>   22


         ENVIRONMENTAL

         EXCO's operations are subject to numerous laws and regulations
governing the discharge of materials into the environment or otherwise relating
to environmental protection. These laws and regulations require the acquisition
of a permit before drilling commences, restrict the types, quantities and
concentration of various substances that can be released into the environment in
connection with drilling and production activities, limit or prohibit drilling
activities on certain lands lying within wilderness, wetlands and other
protected areas, and impose substantial liabilities for pollution which might
result from EXCO's operations. Moreover, the recent trend toward stricter
standards in environmental legislation and regulation is likely to continue. For
instance, legislation has been proposed in Congress from time to time that would
reclassify certain crude oil and natural gas exploitation and production wastes
as "hazardous wastes" which would make the reclassified wastes subject to much
more stringent handling, disposal and clean-up requirements. If such legislation
were to be enacted, it could have a significant impact on the operating costs of
EXCO, as well as the oil and natural gas industry in general. Initiatives to
further regulate the disposal of crude oil and natural gas wastes are also
pending in certain states, and these various initiatives could have a similar
impact on EXCO. EXCO could incur substantial costs to comply with environmental
laws and regulations. In addition to compliance costs, government entities and
other third parties may assert substantial liabilities against owners and
operators of oil and natural gas properties for oil spills, discharge of
hazardous materials, remediation and clean-up costs and other environmental
damages, including damages caused by previous property owners. As a result,
substantial liabilities to third parties or governmental entities may be
incurred, the payment of which could reduce or eliminate the funds available for
project investment or result in loss of EXCO's properties. Although EXCO
maintains insurance coverage it considers to be customary in the industry, it is
not fully insured against certain of these risks, either because such insurance
is not available or because of high premium costs. Accordingly, EXCO may be
subject to liability or may lose substantial portions of properties due to
hazards that cannot be insured against or have not been insured against due to
prohibitive premium costs or for other reasons. The imposition of any such
liabilities on EXCO could have a material adverse effect on EXCO's financial
condition and results of operations.

         The Oil Pollution Act of 1990 ("OPA") imposes a variety of regulations
on "responsible parties" related to the prevention of oil spills. The
implementation of new, or the modification of existing, environmental laws or
regulations, including regulations promulgated pursuant to the Oil Pollution Act
of 1990, could have a material adverse impact on EXCO. While EXCO does not
anticipate incurring material costs in connection with environmental compliance
and remediation, it cannot guarantee that material costs will not be incurred.
See "Business and Properties -- Regulation."

                               RECENT DEVELOPMENTS

CHANGE OF CONTROL

         On December 19, 1997, Mr. Miller purchased (the "Purchase") 413,423
shares of Common Stock. Upon completion of the Purchase, Mr. Miller became the
beneficial owner of approximately 51% of the Common Stock of EXCO.

         The Purchase was effected pursuant to the terms of a Stock Option
Agreement first dated December 8, 1997 among Mr. Miller, on the one hand, and
Richard D. Collins, Dave Fitzgerald, Inc., David N. Fitzgerald, Francis C.
Fitzgerald, W.R. Granberry, Glenn L. Seitz, Suzanne F. Bobo, J.A. Dinger, John
A. Schlensker, Donald C. Thomas, Jr. and R. Scott Collins (collectively, the
"Sellers"), on the other (the "Option Agreement"). The Sellers included members
of EXCO's management and certain affiliates. On December 18, 1997, Mr. Miller
exercised his option to purchase the shares. On December 19, 1997, Mr. Miller
executed a Stock Purchase Agreement among Mr. Miller, on the one hand, and
certain Sellers, on the other (the "Purchase Agreement"). Pursuant to the terms
of the Option Agreement and the Purchase Agreement, the Purchase was consummated
December 19, 1997. In connection with the Purchase, Mr. Miller paid the Sellers
an aggregate of approximately $1,240,269 in cash from personal funds. The
consideration paid by Mr. Miller in connection with the Purchase was determined
by arms' length negotiations between Mr. Miller and the Sellers.

         In addition, on December 19, 1997, the Board of Directors of EXCO held
a meeting at which time the resignations of various officers and directors of
EXCO were tendered and accepted. The Board appointed Mr. Miller as a Director
and then elected him Chairman and Chief Executive Officer of EXCO. The Board
also appointed Mr. Eubank to the Board of Directors and elected him President,
Treasurer and Chief Financial Officer of EXCO. Mr. Dave N. Fitzgerald resigned
as Chairman of the Board of EXCO, Mr. Charles W. Gleeson resigned as President
and Chief Executive Officer of EXCO, Mr. Glenn L. Seitz resigned as a Director
and Treasurer of EXCO, Mr. Richard D. Collins resigned as a Director and
Secretary of EXCO and Mr. W.R. Granberry resigned as a Director of EXCO. Mr.
Richard E. Miller was elected Secretary of EXCO. Messrs. Fitzgerald and Gleeson
remained as Directors of EXCO.

         On December 31, 1997, EXCO issued, in a private placement, 100,000
shares of Common Stock to Mr. Eubank for an aggregate purchase price of
$300,000, or $3.00 per share ($6.00 per share equivalent after adjusting for the
Reverse Stock Split). In addition, on that same date EXCO issued, in a private
placement, 100,000 shares to Mr. Ellis for an aggregate purchase price of
$300,000, or $3.00 per share ($6.00 per share equivalent after adjusting for the
Reverse Stock Split). All of the shares so issued are deemed "restricted" shares
under the Federal securities laws. The $600,000 aggregate gross purchase
consideration will be used as general corporate working capital by EXCO. As of
December 31, 1997, EXCO had outstanding 1,005,300 shares of Common Stock.

         On December 31, 1997, Mr. Eubank resigned as Chief Financial Officer
and Dr. Ramsey was appointed Chief Financial Officer and Vice President of EXCO.

MAVERICK COUNTY ACQUISITION

         EXCO is seeking to grow and diversify its operations through the
acquisition of certain energy assets including producing properties. On January
22, 1998, EXCO entered into a letter of intent to acquire the Maverick County
Properties. On February 11, 1998, EXCO consummated a purchase and sale agreement
for the Maverick County Properties. The purchase price for the Maverick County
Properties was $760,200.

   
         On December 31, 1997, the Maverick County Properties were estimated to
contain 8,011 Bbls of oil and 2,447,785 Mcf of gas or 415,975 Boe of proved
reserves, 98% of which were natural gas, and owned leasehold interests in a
total of 3,744 gross acres (3,123 net acres) of oil and natural gas properties,
9.6% of gross acres which were developed acres. The Maverick County Properties
include 9 gross productive wells (7.0 net productive wells) and 2 gross (1.87 
net) non-producing wells which may require recompletions, workovers or 
abandonment. 
    

                                       21
<PAGE>   24
   
EXCO has identified at least two potential development well locations, one of
which was drilled and completed as a producing gas well in April 1998. The
Maverick County Properties include 360 gross (280 net) developed acres and 3,384
gross (2,843 net) undeveloped acres. Approximately 66% of the estimated proved
reserves of the Maverick County Properties were classified as developed. The
acquisition also includes an 86.9% interest in a natural gas gathering system
and an 88% interest in a natural gas treating facility, both of which were
operated by Osborne Oil Company. The Maverick County Properties were mortgaged
under the Credit Facility. See "Business and Properties of EXCO -- Oil and
Natural Gas Reserves" and "-- Acreage."
    

JACOBI-JOHNSON ACQUISITION

   
         On May 8, 1998, EXCO acquired all of the outstanding common stock of
Jacobi-Johnson. Jacobi-Johnson owns oil and natural gas working interests
located in Polk, Nacogdoches, Navarro, Smith and Wood Counties, Texas. The
Jacobi-Johnson Properties include 34 gross producing (14.3 net producing) wells
with current net production of approximately 59.4 Bbls of oil and 171,000 cubic
feet of natural gas per day. In addition to the producing wells, the
Jacobi-Johnson Properties include working interests in two saltwater disposal
wells. As of December 31, 1997, the Jacobi-Johnson Properties are estimated to
contain proved reserves of 234,985 Bbls of oil and 597,880 Mcf of natural gas.
Approximately 100% of the estimated proved reserves of the Jacobi-Johnson
Properties are classified as developed.
    

   
         The aggregate purchase price paid for the stock was $1,476,451, subject
to post-closing adjustments. Post-closing adjustments may be made if it is
determined within 90 days of the closing that the net working capital of
Jacobi-Johnson as of January 1, 1998 is different than what was calculated at
closing, or if any title problems are discovered within 60 days of the closing.
The Sellers have agreed to indemnify EXCO for amounts arising from any breach by
Sellers, including environmental damages, to the extent such amount exceeds
$20,000. EXCO has agreed to indemnify the Sellers for amounts arising from any
breach by EXCO, to the extent such amount exceeds $20,000. The acquisition was
effective January 1, 1998. The amount of consideration was determined through
arm's length negotiations taking into account estimates of recoverable reserves,
current oil and natural gas prices, the fair market value of other property and
equipment, the amount of cash and cash equivalents on hand, the collectibility
and estimated payment timing of accounts receivable and the amount of current
and long-term liabilities. The consideration consisted of $703,035 cash and
85,436 shares of EXCO Common Stock. EXCO also assumed approximately $260,800 of
Jacobi-Johnson indebtedness. Simultaneously with the Closing, EXCO paid in full
approximately $245,000 of Jacobi-Johnson's outstanding indebtedness owed to 
Southside  Bank. EXCO obtained the cash for the purchase price and payoff of
the Southside Bank loans under the Credit Facility. The Jacobi-Johnson
Properties have been mortgaged under the Credit Facility.
    

GLADSTONE MERGER

   
         On May 1, 1998, EXCO entered into the Merger Agreement with Gladstone.
Gladstone is a Dallas, Texas based oil and natural gas production company with
properties in Kent, Stonewall, Schleicher, Pecos and Madison Counties, Texas,
and San Juan County, New Mexico. 
    


   
         Under terms of the Merger Agreement, Gladstone stockholders will 
receive approximately $1.4 million, or $.33 per share, in cash. It is currently
anticipated that the transaction will close during the third quarter of 1998,
with EXCO being the surviving corporation. EXCO intends to fund this
transaction with the net proceeds of the Rights Offering, unless the merger can
be completed prior to completion of the Rights Offering, in which case EXCO
will fund the merger with borrowings under the Credit Facility. The transaction
is subject to customary conditions of closing including review by the
Securities and Exchange Commission of Gladstone's proxy materials, approval by
Gladstone's board of directors and stockholders, approval by EXCO's board of
directors and due diligence inspection by EXCO. EXCO can offer no assurance
that the merger will be approved or that the transaction will be completed.
    

   
         In addition to the Merger Agreement, as of May 1, 1998, EXCO entered 
into a Stock Option Agreement with one Gladstone stockholder, Mr. Brooks,
granting EXCO an option to acquire 1,910,000 shares, or approximately 44.8%, of
Gladstone's issued and outstanding common stock at a price of $.33 per share.
Mr. Brooks is Chairman and President of Gladstone. As of May 1, 1998, EXCO also
entered into a Stockholder Agreement whereby three Gladstone stockholders,
Deborah Brooks Garrett, Rebecca B. Feldt and Carol Brady, have agreed to vote
their
    

                                       22

shares in favor of the merger with EXCO. These stockholders own 351,000 shares
each or approximately 8.3% each of Gladstone's outstanding common stock.
    

   
DAWSON COUNTY ACQUISITION
    


   
         On May 29, 1998, EXCO executed a non-binding letter of intent to
acquire from J.M. Hill, J.M. Hill, Trustee, Walter O. Hill, and Steven J. Devos,
the Dawson County Properties. The Dawson County Properties include 11 gross (3.4
net) producing wells with current net production of 69.4 Bbls of oil and 37 Mcf
of natural gas per day and 4 gross (.85 net) saltwater disposal and
non-producing wells which may require recompletions, workovers or abandonment.
The Dawson County Properties include 645 gross (251 net) developed acres and 889
gross (119 net) undeveloped acres. The purchase price is $1,364,000 cash to be
paid for using funds available under EXCO's Credit Facility. The parties are
currently in the process of negotiating definitive purchase documents which EXCO
anticipates will contain customary representations and indemnities. EXCO
currently anticipates completing this acquisition in June 1998. There can be no
assurance the transaction will be completed.
    

CREDIT FACILITY

   
         On February 11, 1998, EXCO entered into the Credit Facility with
NationsBank of Texas, N.A. The Credit Facility provides for borrowings not to
exceed  $50 million, subject to borrowing base limitations. The Credit Facility
consists of a regular revolver which at May 15, 1998, had a borrowing base of
$3.5 million. On May 15, 1998 approximately $1,325,000 was available to be
borrowed under the Credit Facility. A portion of the borrowing base is available
for the issuance of letters of credit. All borrowings under the Credit Facility
are secured by a first lien deed of trust providing a security interest in
tangible and intangible assets representing at least 90% of the estimated
present value of EXCO's oil and natural gas properties. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources."
    

ANNUAL MEETING OF SHAREHOLDERS

         On March 31, 1998 EXCO held its Annual Meeting of Shareholders (the
"Meeting"). Several Board proposals, including two amendments to the Restated
Articles of Incorporation, were approved by the shareholders at the Meeting.

         BOARD OF DIRECTORS

         At the Meeting, the shareholders considered and approved the Board's
proposal to amend the Restated Articles of Incorporation to allow the Board to
fix the number of directors by resolution. At the Meeting, the shareholders
elected Messrs. Miller, Eubank, Ramsey, Pickens, Smith, Ellis and Muckleroy as
directors.

         REVERSE STOCK SPLIT

   
         At the Meeting, the shareholders considered and approved an amendment
to the Restated Articles of Incorporation to effect a one-for-two reverse stock
split, to maintain the number of authorized shares of Common Stock at 25,000,000
and to double the par value of the Common Stock from $0.01 to $0.02 per share.
EXCO effected the Reverse Stock Split effective March 31, 1998.
    

         1998 STOCK OPTION PLAN

         At the Meeting, the shareholders approved the EXCO Resources, Inc. 1998
Stock Option Plan (the "1998 Stock Option Plan") effective as of March 13, 1998.

   
         Under the 1998 Stock Option Plan, any EXCO employee (including an
employee who is also a director or an officer), consultants or directors may
receive incentive compensation based on criteria established by the Board of
Directors. Options to purchase up to 1,000,000 shares (as adjusted for the
Reverse Stock Split) may be granted under the 1998 Stock Option Plan.

                                 USE OF PROCEEDS

   
         The total proceeds (assuming a $6.00 per share Subscription Price for
the purposes of this table) from the Rights Offering are estimated to be
approximately $35,660,160 (assuming all Rights are exercised). The following
table sets forth the proposed sources and uses of funds from the Rights
Offering. For a description of the Rights Offering, see "The Rights Offering."
    

   
         To the extent EXCO raises proceeds from the Rights Offering, EXCO
intends to first repay its indebtedness and then fund the Gladstone Merger, any
excess proceeds will be invested in short term, interest bearing debt
obligations of the federal government or investment grade corporate borrowers
and certificates of deposit and similar federally insured obligations.
    

   
         There is no minimum amount required to be subscribed for pursuant to
the Rights Offering. Moreover, the Standby Commitment is conditioned upon at
least 3,000,000 shares being subscribed for by holders of Rights. There is no
assurance that 3,000,000 shares will be subscribed for. Nevertheless, EXCO
intends to complete the Rights Offering regardless of the number of shares that
may be subscribed for. Accordingly, the actual net proceeds from the Rights
Offering could be less than the amounts shown in the following table.

</TABLE>
    


   
         (1)  Includes repayment of approximately $2.2 million outstanding under
              EXCO's Credit Facility (including $600,000 borrowed on February
              11, 1998 as a result of the Maverick County Acquisition, $900,000
              borrowed on May 8, 1998 as a result of the Jacobi-Johnson
              Acquisition), and $1.4 million intended to be drawn in June 1998
              to fund the Dawson County Acquisition. See "Management's
              Discussion and Analysis of Financial Condition and Results of
              Operations -- Liquidity and Capital Resources -- New Credit
              Facility" for additional information with respect to the terms of
              the Credit Facility, including the interest rate. 
         (2)  If EXCO completes the merger with Gladstone before completion of
              the Rights Offering, indebtedness would be increased by $1.4
              million to $5.1 million. At the time of the Rights Offering, then,
              $5.1 million of the net proceeds of the Rights Offering would be
              used to repay indebtedness, and working capital will be $30.4
              million.
         (3)  These excess funds, as well as funds available to be borrowed
              under the Credit Facility, will be available to EXCO to fund the
              exploitation, development, exploration or acquisition of natural
              gas properties and for other general corporate purchases. While
              EXCO regularly evaluates potential acquisition opportunities,
              other than in respect of the Gladstone Merger and the Dawson
              County Acquisition (see "Recent Developments -- Gladstone Merger"
              and "Recent Developments -- Dawson County Acquisition"), EXCO does
              not have any agreements or understandings with respect to any

                                    DILUTION

   
         The net tangible book value of the Common Stock as of March 31, 1998,
was $770,000 or $1.51 per share. Net tangible book value per share represents
total tangible assets less total liabilities, divided by the number of shares of
Common Stock outstanding, on a fully diluted basis excluding stock options.
After giving effect to the consummation of the Rights Offering (assuming a $6.00
per share Subscription Price and the exercise of all Rights offered hereby for
the purposes of this table) and the application of the net proceeds therefrom,
the issuance of 85,436 shares of Common Stock at $6.00 per share for the
Jacobi-Johnson transaction closed on May 8, 1998, the net tangible book value of
EXCO as of March 31, 1998, would have been approximately $36,783,000, or $5.63
per share (before giving effect to the cash buy-back of fractional shares
pursuant to the Reverse Stock Split). This represents an immediate increase in
net tangible book value of $4.12 per share with respect to shares outstanding
prior to the Rights Offering and an immediate dilution of $.37 per share with
respect to shares purchased upon the exercise of Rights, as illustrated in the
following table:

DIVIDEND POLICY

   
         EXCO has never paid cash dividends on its Common Stock and does not
anticipate paying cash dividends on its Common Stock in the foreseeable future.
EXCO anticipates that any income generated in the foreseeable future will be
retained for the development and expansion of its business. The Credit Facility
prohibits EXCO from paying dividends on its Common Stock. Future dividend policy
is subject to the discretion of the Board and will depend upon a number of
factors, including future earnings, debt service, capital requirements,
restrictions in EXCO's Credit Facility, business conditions, the financial
condition of EXCO and other factors that the Board deems relevant.

                               THE RIGHTS OFFERING

THE RIGHTS

         EXCO is distributing transferable Rights to the record holders of its
outstanding Common Stock as of the Record Date, at no cost to such record
holders. EXCO will distribute ten Rights for each share of Common Stock held on
the Record Date. One Right will entitle the holder to purchase one share of
Common Stock. The Rights will be evidenced by transferable Subscription
Certificates.

         No Subscription Certificate may be divided in such a way as to permit
the holder of such Certificate to receive a greater number of Rights than the
number to which such Subscription Certificate entitles its holder, except that a
depository, bank, trust company or securities broker or dealer holding shares of
Common Stock on the Record Date for more than one beneficial owner may, upon
proper showing to the Subscription Agent, exchange its Subscription Certificate
to obtain a Subscription Certificate for the number of Rights to which all such
beneficial owners in the aggregate would have been entitled had each been a
record holder of Common Stock on the Record Date.

SUBSCRIPTION PRIVILEGES

         BASIC SUBSCRIPTION PRIVILEGE

         Each Right will entitle the holder thereof to receive, upon payment of
the Subscription Price, one share of Common Stock. Certificates representing
shares of Common Stock purchased pursuant to the Basic Subscription Privilege
will be delivered to subscribers as soon as practicable after the Expiration
Date, irrespective of whether the Subscription Privilege is exercised
immediately prior to the Expiration Date or earlier.

         OVERSUBSCRIPTION PRIVILEGE

         Subject to the allocation described below, each Right also carries the
right to subscribe for additional Rights to acquire additional shares of Common
Stock at the Subscription Price not subscribed for through the exercise of the
Basic Subscription Privilege by other Rights holders (the "Excess Shares"). Only
Rights holders who exercise the Basic Subscription Privilege in full will be
entitled to exercise the Oversubscription Privilege.

   
         In no event, however, may the holder oversubscribe for more than 100%
of the shares purchased by the holder in the Basic Subscription Privilege. If
the number of shares available taking into account the aforementioned
restrictions are not sufficient to satisfy the oversubscriptions, the available
shares will be allocated pro rata (subject to elimination of fractional shares)
among the holders of Rights who exercise the Oversubscription Privilege, in
proportion, not to the number of shares requested pursuant to the
Oversubscription Privilege, but to the number of shares each beneficial holder
has purchased pursuant to the Basic Subscription Privilege; provided, however,
that if such pro rata allocation results in any holder being allocated a greater
number of shares than such holder subscribed for pursuant to the exercise of
such holder's Oversubscription Privilege, then such holder will be allocated
only such number of shares as such holder subscribed for pursuant to the
Oversubscription Privilege and the remaining shares will be allocated among all
other holders exercising the Oversubscription Privilege.
    

         Holders desiring to exercise their Oversubscription Privilege should
indicate in the space provided on their Subscription Certificate the number of
additional shares they would like to subscribe for. As soon as practicable
following the Expiration Date, EXCO will determine the number of shares of
Common Stock that may be purchased pursuant to the Oversubscription Privilege.
Holders must tender with their Subscription Certificate the full amount due on
exercise of their Oversubscription Privilege for that number of shares they have
so subscribed for (in addition to the payment due on the Basic Subscription
Privilege).

         Certificates representing Excess Shares purchased pursuant to the
Oversubscription Privilege will be delivered to subscribers as soon as
practicable after the Expiration Date and after all prorations and adjustments
contemplated by the terms of the Rights Offering have been effected. EXCO will
also repay, without interest,

                                       28

<PAGE>   31


subscribing holders for any overpayment on the amount determined to be due with
respect to such subscriber's Oversubscription Privilege.

         Banks, brokers and other nominee holders of Rights who exercise the
Basic Subscription Privilege and the Oversubscription Privilege on behalf of
beneficial owners of Rights will be required to certify to the Subscription
Agent and EXCO, in connection with the exercise of the Oversubscription
Privilege, as to the aggregate number of Rights that have been exercised and the
number of shares of Common Stock that are being subscribed for pursuant to the
Oversubscription Privilege by each beneficial owner of Rights on whose behalf
such nominee holder is acting.

EXPIRATION DATE

         The Rights will expire at 5:00 p.m., Dallas time, on ________, 1998,
unless extended by EXCO. After the Expiration Date, unexercised Rights will be
null and void. EXCO will not be obligated to honor any purported exercise of
Rights received by the Subscription Agent after the Expiration Date, regardless
of when the documents relating to such exercise were sent, except pursuant to
the Guaranteed Delivery Procedures described below.

DETERMINATION OF SUBSCRIPTION PRICE

   
         The Subscription Price was determined by EXCO and its Board of
Directors. The Subscription Price was determined after considering such factors
as the price paid by Messrs. Miller, Eubank and Ellis for the purchase of their
shares in December 1997 after taking into account the Reverse Stock Split, the
current trading price for the Common Stock, future prospects of EXCO, the
industry in general and EXCO's position in the industry, market valuations of
the securities of companies engaged in similar activities, the quality of the
management team and negotiations with the Standby Purchaser. The Subscription
Price should not be considered an indication of the actual value of EXCO or its
Common Stock. There can be no assurance that the market price of the Common
Stock will not decline during the subscription period or that, following the
issuance of the Rights and of the Common Stock upon exercise of Rights, a
subscribing Rights holder will be able to sell shares of Common Stock purchased
in the Rights Offering at a price equal to or greater than the Subscription
Price.
    

         At the time the Subscription Price for the Rights Offering was
determined, such price represented a ___% discount to the market price for
EXCO's Common Stock. The market price for EXCO's Common Stock is expected to
decrease by an amount that approximates the value of the Rights when the Rights
are distributed and begin to trade as a separate security.

EXERCISE OF RIGHTS

   
         Rights may be exercised by delivery to the Subscription Agent, on or
prior to the Expiration Date, of the properly completed and duly executed
Subscription Certificate evidencing such Rights (together with any required
signature guarantees), accompanied by payment in full of the Subscription Price
for each share of Common Stock subscribed for pursuant to the Basic Subscription
Privilege and the Oversubscription Privilege (except as permitted pursuant to
clause (iii) of the next sentence). Such payment in full must be made by (i)
check or bank draft drawn upon a United States bank or a postal, telegraphic or
express money order payable to "Continental Stock Transfer, as Subscription
Agent"; or (ii) wire transfer of funds to the account maintained by the
Subscription Agent for such purpose at Chase Manhattan Account No. 777-009625,
ABA No. 021000021; or (iii) in such other manner as EXCO may approve in writing
in the case of persons acquiring an aggregate number of shares of Common Stock
totaling $1,500,000 or more, provided that in such case the full amount of such
Subscription Price is received by the Subscription Agent in currently available
funds within one OTC trading day prior to the Expiration Date (the payment
method under (iii) being an "Approved Payment Method"). Payment of the
Subscription Price will be deemed to have been received by the Subscription
Agent only upon (a) clearance of any uncertified check, (b) receipt by the
Subscription Agent of any certified check or bank draft drawn upon a U.S. bank
or of any postal, telegraphic or express money order, (c) receipt of good funds
in the Subscription Agent's account designated above or (d) receipt of funds by
the Subscription Agent through an Approved Payment Method. PLEASE NOTE THAT
FUNDS PAID BY UNCERTIFIED PERSONAL CHECK MAY TAKE AT LEAST FIVE BUSINESS DAYS TO
CLEAR. ACCORDINGLY, HOLDERS WHO WISH TO PAY THE SUBSCRIPTION PRICE BY MEANS OF
    

                                       29

<PAGE>   32


UNCERTIFIED PERSONAL CHECK ARE URGED TO MAKE PAYMENT SUFFICIENTLY IN ADVANCE OF
THE EXPIRATION DATE TO ENSURE THAT SUCH PAYMENT IS RECEIVED AND CLEARS BY SUCH
DATE, AND ARE URGED TO CONSIDER PAYMENT BY MEANS OF CERTIFIED OR CASHIER'S
CHECK, MONEY ORDER OR WIRE TRANSFER OF FUNDS.

         Subscription Certificates and payment of the Subscription Price should
be delivered to the address set forth below under "-- Subscription Agent."

         If a Rights holder wishes to exercise Rights, but time will not permit
such holder to cause the Subscription Certificate(s) evidencing such Rights to
reach the Subscription Agent on or prior to the Expiration Date, such Rights may
nevertheless be exercised if all of the following conditions (the "Guaranteed
Delivery Procedures") are met:

                  (i) such holder has caused payment in full of the Subscription
         Price for each share of Common Stock being subscribed for pursuant to
         the Basic Subscription Privilege and the Oversubscription Privilege to
         be received (in the manner set forth above) by the Subscription Agent
         on or prior to the Expiration Date;

                  (ii) the Subscription Agent receives, on or prior to the
         Expiration Date, a notice of guaranteed delivery (a "Notice of
         Guaranteed Delivery"), substantially in the form provided with the
         Instructions distributed with the Subscription Certificates, from a
         member firm of a registered national securities exchange or a member of
         the National Association of Securities Dealers, Inc., or a commercial
         bank or trust company having an office or correspondent in the United
         States, stating the name of the exercising Rights holder, the number of
         Rights represented by the Subscription Certificate(s) held by such
         exercising holder, the number of shares of Common Stock being
         subscribed for pursuant to the Basic Subscription Privilege and the
         number of shares, if any, being subscribed for pursuant to the
         Oversubscription Privilege, and guaranteeing the delivery to the
         Subscription Agent of any Subscription Certificate(s) evidencing such
         Rights within three OTC trading days following the date of the Notice
         of Guaranteed Delivery; and

   
                  (iii) the properly completed and duly executed Subscription
         Certificate(s), including any required signature guarantees, evidencing
         the Rights being exercised is received by the Subscription Agent within
         three OTC trading days following the date of the Notice of Guaranteed
         Delivery relating thereto. The Notice of Guaranteed Delivery may be
         delivered to the Subscription Agent in the same manner as Subscription
         Certificates at the addresses set forth below, or may be transmitted to
         the Subscription Agent by facsimile transmission (facsimile no. (212)
         509-5150). Additional copies of the form of Notice of Guaranteed
         Delivery are available upon request from Continental Stock Transfer &
         Trust Company.
    

         Unless a Subscription Certificate (i) provides that the shares of
Common Stock to be issued pursuant to the exercise of Rights represented thereby
are to be delivered to the record holder of such Rights or (ii) is submitted for
the account of a member firm of a registered national securities exchange or a
member of the National Association of Securities Dealers, Inc., or a commercial
bank or trust company having an office or correspondent in the United States,
signatures on such Subscription Certificate must be guaranteed by an eligible
guarantor institution ("Eligible Guarantor Institution") as defined in Rule
17Ad-15 of the Exchange Act, subject to the standards and procedures adopted by
the Subscription Agent.

         Funds received in payment of the Subscription Price for Excess Shares
subscribed for pursuant to the Oversubscription Privilege will be held in a
segregated account pending issuance of such Excess Shares. If a Rights holder
exercising the Oversubscription Privilege is allocated less than all of the
Excess Shares that such holder wished to subscribe for pursuant to the
Oversubscription Privilege, the excess funds paid by such holder in respect of
the Subscription Price for shares not issued will be returned by mail without
interest or deduction as soon as practicable after the Expiration Date.

         A holder who holds shares of Common Stock for the account of others,
such as a broker, a trustee or a depositary for securities, should notify the
respective beneficial owners of such shares as soon as possible to ascertain
such beneficial owners' intentions and to obtain instructions with respect to
the Rights beneficially owned by them.


                                       30

<PAGE>   33


Beneficial owners of Common Stock or Rights held through such a holder of record
should contact the holder and request the holder to effect transactions in
accordance with the beneficial owner's instructions.

         If either the number of Rights being exercised is not specified on a
Subscription Certificate, or the payment delivered is not sufficient to pay the
full aggregate Subscription Price for all shares of Common Stock stated to be
subscribed for, the Rights holder will be deemed to have exercised the maximum
number of Rights that could be exercised for the amount of the payment delivered
by such Rights holder. If the payment delivered by the Rights holder exceeds the
aggregate Subscription Price for the number of Rights evidenced by the
Subscription Certificate(s) delivered by such Rights holder, the payment will be
applied, until depleted, to subscribe for shares of Common Stock in the
following order: (i) to subscribe for the number of shares, if any, of Common
Stock indicated on the Subscription Certificate(s) pursuant to the Basic
Subscription Privilege; (ii) to subscribe for shares of Common Stock until the
Basic Subscription Privilege has been fully exercised with respect to all of the
Rights represented by the Subscription Certificate; and (iii) to subscribe for
additional shares of Common Stock pursuant to the Oversubscription Privilege
(subject to any applicable proration). Any excess payment remaining after the
foregoing allocation will be returned to the Rights holder as soon as
practicable by mail, without interest or deduction.

         The Instructions accompanying the Subscription Certificates should be
read carefully and followed in detail. DO NOT SEND SUBSCRIPTION CERTIFICATES TO
EXCO.

         THE METHOD OF DELIVERY OF SUBSCRIPTION CERTIFICATES AND PAYMENT OF THE
SUBSCRIPTION PRICE TO THE SUBSCRIPTION AGENT WILL BE AT THE ELECTION AND RISK OF
THE RIGHTS HOLDERS, BUT IF SENT BY MAIL IT IS RECOMMENDED THAT SUCH CERTIFICATES
AND PAYMENTS BE SENT BY REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT
REQUESTED, AND THAT A SUFFICIENT NUMBER OF DAYS BE ALLOWED TO ENSURE DELIVERY TO
THE SUBSCRIPTION AGENT AND CLEARANCE OF PAYMENT PRIOR TO THE EXPIRATION DATE.
BECAUSE UNCERTIFIED PERSONAL CHECKS MAY TAKE AT LEAST FIVE BUSINESS DAYS TO
CLEAR, RIGHTS HOLDERS ARE STRONGLY URGED TO PAY, OR ARRANGE FOR PAYMENT, BY
MEANS OF CERTIFIED OR CASHIER'S CHECK, MONEY ORDER OR WIRE TRANSFER OF FUNDS.

         All questions concerning the timeliness, validity, form and eligibility
of any exercise of Rights will be determined by EXCO, whose determinations will
be final and binding. EXCO, in its sole discretion, may waive any defect or
irregularity, or permit a defect or irregularity to be corrected within such
time as it may determine, or reject the purported exercise of any Right by
reason of any defect or irregularity in such exercise. Subscriptions will not be
deemed to have been received or accepted until all irregularities have been
waived or cured within such time as EXCO determines in its sole discretion.
Neither EXCO nor the Subscription Agent will be under any duty to give
notification of any defect or irregularity in connection with the submission of
Subscription Certificates or incur any liability for failure to give such
notification.

         Any questions or requests for assistance concerning the method of
exercising Rights or requests for additional copies of this Prospectus, the
Instructions or the Notice of Guaranteed Delivery should be directed to:

FOREIGN AND CERTAIN OTHER SHAREHOLDERS

         Subscription Certificates will not be mailed to holders whose addresses
are outside the United States or who have an APO or FPO address, but will be
held by the Subscription Agent for their account. To exercise or sell Rights,
such holders must notify the Subscription Agent by completing an International
Holder Subscription Form, which will be delivered to such holders in lieu of a
Subscription Certificate, and sending it by mail to the Subscription Agent at
the address specified above. International Holder Subscription Forms must be
returned to the Subscription Agent at or prior to 11:00 a.m., Eastern time, on
the date that is four OTC Bulletin Board trading days prior to the Expiration
Date, at which time (if no instructions have been received) the Rights
represented thereby will be sold, if feasible, by the Subscription Agent and the
net proceeds, if any, remitted to such holders. If the Rights can be sold by the
Subscription Agent, sales of such Rights will be deemed to have been effected at
the weighted average price received by the Subscription Agent on the day such
Rights are sold, less any applicable brokerage commissions, taxes and other
expenses.
    

NO REVOCATION

         AFTER A HOLDER OF RIGHTS HAS EXERCISED THE BASIC SUBSCRIPTION PRIVILEGE
OR THE OVERSUBSCRIPTION PRIVILEGE, SUCH EXERCISE MAY NOT BE REVOKED BY SUCH
RIGHTS HOLDER.

METHOD OF TRANSFERRING RIGHTS

         Rights may be purchased or sold through usual investment channels,
including banks and brokers. It is anticipated that the Rights will be traded on
the OTC until the close of business on the last OTC trading day preceding the
Expiration Date.

         The Rights evidenced by a single Subscription Certificate may be
transferred in whole by endorsing the Subscription Certificate for transfer in
accordance with the Instructions. A portion of the Rights evidenced by a single
Subscription Certificate (but not fractional Rights) may be transferred by
delivering to the Subscription Agent a Subscription Certificate properly
endorsed for transfer, with instructions to register such portion of the Rights
evidenced thereby in the name of the transferee (and to issue a new Subscription
Certificate to the transferee evidencing such transferred Rights). In such
event, a new Subscription Certificate evidencing the balance of the Rights will
be issued to the Rights holder or, if the holder so instructs, to an additional
transferee.

         Rights holders wishing to transfer all or a portion of their Rights
(but not fractional Rights) should allow a sufficient amount of time prior to
the Expiration Date for (i) the transfer instructions to be received and
processed by the Subscription Agent, (ii) a new Subscription Certificate to be
issued and transmitted to the transferee or transferees with respect to
transferred Rights, and to the transferor with respect to retained Rights, if
any, and (iii) the Rights evidenced by such new Subscription Certificates to be
exercised or sold by the recipients thereof. Neither EXCO nor the Subscription
Agent shall have any liability to a transferee or transferor of Rights if
Subscription Certificates are not received in time for exercise or sale prior to
the Expiration Date.

         Except for the fees charged by the Subscription Agent (which will be
paid by EXCO as described herein), all commissions, fees and other expenses
(including brokerage commissions and transfer taxes) incurred in connection with
the purchase, sale or exercise of Rights will be for the account of the
transferor of the Rights, and none of such commissions, fees or expenses will be
paid by EXCO or the Subscription Agent.

PROCEDURES FOR BOOK ENTRY TRANSFER FACILITY PARTICIPANTS

         EXCO anticipates that the Rights will be eligible for transfer through,
and that the exercise of the Basic Subscription Privilege may be effected
through, the facilities of Depository Trust Company ("DTC"). Rights exercised
through DTC are referred to herein as "DTC Exercised Rights." The holder of a
DTC Exercised Right may exercise the Oversubscription Privilege in respect of
such DTC Exercised Right by properly executing and delivering to the
Subscription Agent on or prior to the Expiration Date, a DTC Participant
Oversubscription Exercise Form, together with payment of the appropriate
Subscription Price for the number of shares of Common Stock for which


                                       32

<PAGE>   35


   
the Oversubscription Privilege is to be exercised. Copies of the DTC Participant
Oversubscription Exercise Form may be obtained from Continental Stock Transfer &
Trust Company.
    

SUBSCRIPTION AGENT

   
         EXCO has appointed Continental Stock Transfer & Trust
Company as Subscription Agent for the Rights Offering. The Subscription Agent's
address, which is the address to which the Subscription Certificates and payment
of the Subscription Price should be delivered, as well as the address to which
Notice of Guaranteed Delivery must be delivered, is:

                                            Continental Stock Transfer
                                            Reorganization Department
                                            2 Broadway, 19th Floor
                                            New York, NY   10004

         The Subscription Agent's telephone number is (212) 509-4000, ext. 226,
and its facsimile number is (212) 509-5150.

         EXCO will pay the fees and expenses of the Subscription Agent (which
are estimated will aggregate $12,000), and has also agreed to indemnify the
Subscription Agent from any liability which it may incur in connection with the
Rights Offering.

STANDBY PURCHASE AGREEMENT 
    

   
         EXCO and the Standby Purchaser have entered into a Standby Purchase
Agreement, pursuant to which the Standby Purchaser has agreed to purchase at the
Subscription Price a number of shares of Common Stock equal to the number of
shares of Common Stock not purchased pursuant to the exercise of Rights with a
minimum of 1,000,000 shares to be purchased and up to a maximum of 2,000,000
shares to be purchased. The Standby Purchaser's obligation to purchase any
shares of Common Stock is conditioned upon holders of Rights exercising Rights
to purchase at least 3,000,000 shares of Common Stock, including 250,000 shares
which must be purchased by Mr. Miller. Mr. Miller has stated to EXCO that he
intends to purchase at least 250,000 shares pursuant to the exercise of Rights
issued to him. The Standby Purchaser has agreed to acquire the shares of Common
Stock at a price per share equal to the Subscription Price. If the Standby
Purchaser declines to purchase the shares of Common Stock because of EXCO's
failure to satisfy the threshold sales requirements, then EXCO is required to
reimburse the Standby Purchaser for reasonable fees and expenses in connection
with the proposed purchase.
    

   
         Pursuant to the obligations of the Standby Purchase Agreement, the
Standby Purchaser warrants to EXCO that it is purchasing the shares of Common
Stock for its own account and without any intent to sell or transfer the shares
in violation of the Securities Act. Pursuant to the obligations of the Standby
Purchase Agreement, EXCO makes certain representations to the Standby Purchaser
as to EXCO's timely filing of accurate documents with the Securities and
Exchange Commission, the valid issuance of EXCO's Common Stock, the
enforceability of the Standby Purchase Agreement, the current capitalization of
EXCO, and that EXCO is duly incorporated and in good standing in Texas. In
addition to the conditions described above, the rights and obligations of EXCO
and the Standby Purchaser are subject to certain customary conditions, including
the absence of any pending or threatened action, suit or proceeding relating to
the Rights Offering or the Standby Purchase Agreement. EXCO has also agreed to
expand its Board of Directors to add one new director to be nominated by the
Standby Purchaser.

(1)    The data for all prior years has been restated to reflect the change in
       EXCO's method of accounting for oil and natural gas operations to the
       full cost method of accounting. See Note 2 to EXCO's Financial
       Statements. As a result of the change in the accounting method, net
       income has been increased by $44,000 ($0.15 per share) for the year ended
       March 31, 1994; the net loss for the year ended March 31, 1995, the nine
       month period ended December 31, 1995 and the year ended December 31,
       1996, has been decreased $40,000 ($0.12 per share), $184,000 ($0.54 per
       share) and $3,000 ($0.01 per share), respectively.
(2)    The $303,000 expense in fiscal 1996 represents the legal, accounting
       and other expenses associated with the attempted acquisition by EXCO of
       Taurus Energy Corp.
   
(3)    Per share data has been restated to reflect the one-for-five reverse
       stock split effective July 19, 1996 and the Reverse Stock Split effective
       March 31, 1998. The adoption of Financial Accounting Standards Board No.
       128, Earnings per Share, did not have a material impact on net income
       (loss) per share amounts reported herein.
    
(4)    EXCO has not declared nor paid any dividends during any of the periods
       presented.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

   
         COMPARISON OF THREE MONTHS ENDED MARCH 31, 1998 AND 1997

         Revenues. EXCO's oil and natural gas revenues for the three month
period ended March 31, 1998 decreased $46,000, or 21%, to $173,000 versus
$219,000 for the corresponding period of 1997. The decrease in revenues was
primarily due to lower oil and gas prices in the current quarter and the fact
that revenues from newly acquired properties were partially offset by the
absence of revenue from properties that were sold after the first quarter of the
prior year.

         EXCO sold 2,816 Bbls of crude oil during the quarter ended March
31, 1998 versus 4,972 Bbls in the corresponding quarter of 1997, a 43% decrease.
EXCO sold 72,525 Mcf of natural gas during the current quarter versus
43,120 Mcf in the first quarter of 1997, a 68% increase. The decrease in oil
volume was attributable to the sale in mid-1997 of several non-strategic oil
properties. The increase in gas volume was due to the acquisition of the
Maverick County properties effective January 1, 1998.

         The average oil price received during the three months ended March 31,
1998 was $13.66 versus $21.50 for the three months ended March 31, 1997, a $7.84
per barrel or 36% decrease. The average gas price received during the current
quarter was $1.86 versus $2.60 for the corresponding quarter of the prior year,
a $0.74 per Mcf or 28% decrease.

         Costs and Expenses. Costs and expenses for the three month period ended
March 31, 1998 increased by $139,000, or 58%, to $377,000 as compared to
$238,000 for the corresponding period of 1997. This was primarily due to a
$133,000 increase in general and administrative costs in the current quarter.
This increase reflects EXCO's increased staffing and new focus on reserve
acquisitions. Other variances between the costs and expenses for the first
quarters of 1998 and 1997 are minimal.

         Net Income (Loss). EXCO had a net loss for the quarter ended March 31,
1998 of $194,000 compared to a net loss of $8,000 for the corresponding quarter
of 1997, representing $(.38) and $(.02) per share, respectively. Earnings per
share figures are based on restated weighted average shares outstanding after
the retroactive effect of the one-for-two reverse stock split approved at the
EXCO's shareholders' meeting held on March 31, 1998.
    

         COMPARISON OF YEAR ENDED DECEMBER 31, 1996 AND DECEMBER 31, 1997

   
         Revenues. Oil and natural gas revenues decreased $202,000, or 23%, to
$670,000 for the fiscal year ended December 31, 1997 from $872,000 for the
fiscal year ended December 31, 1996. The decrease was due primarily to the sale
during 1997 of certain non-strategic oil and natural gas properties which lead
to decreased production volumes. Oil and natural gas prices for 1997 were 4%
lower and 14% higher, respectively, than such prices in 1996. Oil and natural
gas sales volumes for 1997 decreased 35% and 19%, respectively, from 1996 as a
result of property sales and the continued depletion of existing properties.

         Other income for the fiscal year ended December 31, 1997 was $28,000 as
compared to $39,000 for the fiscal year ended December 31, 1996. This income
primarily includes well supervision fees and interest income. Prior years have
been restated to reflect a change in classification of fees from overhead
charges billed to working interest owners, including EXCO. These overhead
charges have previously been recorded as management fee revenue and are now
recorded as a reduction in general and administrative expenses.
    

         Costs and Expenses. EXCO's costs and expenses decreased $334,000, or
27%, to $903,000 for the fiscal year ended December 31, 1997 from $1,237,000 for
the fiscal year ended December 31, 1996. This decrease was due primarily to
expenses of $303,000 incurred in 1996 in connection with EXCO's attempted
acquisition of Taurus Energy Corp. Oil and natural gas production costs
decreased $107,000 to $322,000 for 1997 from $429,000 in 1996


                                       35

as a result of the property sales, and general and administrative expenses
increased $113,000 to $486,000 in 1997 from $373,000 in 1996 due to various
increases in office expenses and a reduction in billed salary reimbursement as a
result of the disposition of a certain oil property.

         In 1997, EXCO changed its method of accounting for oil and natural gas
properties from successful efforts to the full cost method of accounting. Prior
years have been restated to reflect this change in accounting method as though
EXCO had been using the full cost method for all periods being compared.
Effective December 31, 1997, EXCO effected a quasi-reorganization through the
application of $8,799,000 of its additional paid-in capital account to eliminate
its accumulated deficit.

         Net Income (Loss). Net loss for the fiscal year ended December 31, 1997
was $205,000, or $.51 per share, compared to a loss of $326,000, or $.85 per
share, for the fiscal year ended December 31, 1996. This $121,000 decrease was
primarily the result of a decrease in revenues being partially offset by a
decrease in expenses as more fully described above.

         COMPARISON OF NINE MONTH TRANSITION PERIOD ENDED DECEMBER 31, 1995 AND
         THE FISCAL YEAR ENDED DECEMBER 31, 1996

         Comparative Periods. On February 13, 1996, EXCO changed its fiscal year
end from March 31 to December 31. As a result, the following comparison is
between the fiscal year ended December 31, 1996 and the nine month transition
period ended December 31, 1995.

   
         Revenues. Oil and natural gas revenues increased $312,000, or 56%, to
$872,000 for the fiscal year ended December 31, 1996 from $560,000 for the nine
month transition period ended December 31, 1995. The increase in oil and natural
gas revenues was primarily attributable to higher oil and natural gas prices in
fiscal 1996 as well as increased production volumes. Oil and natural gas prices
for the fiscal year ended December 31, 1996, were 24% higher and 34% higher,
respectively, than such prices in the nine month transition period ended
December 31, 1995. Oil and natural gas production for the fiscal year ended
December 31, 1996, increased 16% and 24%, respectively, from the nine month
transition period ended December 31, 1995. These increases were primarily
attributable to the production from several successful workovers and newly
completed wells overshadowing the continued depletion of existing properties.
    

         Management fees and other income decreased $37,000, or 49%, to $39,000
for the fiscal year ended December 31, 1996 from $76,000 in the nine month
transition period ended December 31, 1995. Management fees and other income
primarily include well supervision fees and interest income. The decrease was
due primarily to a lower level of operated drilling and maintenance activities.

         Costs and Expenses. EXCO's costs and expenses increased $441,000, or
55%,to $1,237,000 for the fiscal year ended December 31, 1996 from $796,000 for
the nine month transition period ended December 31, 1995. This increase was due
primarily to the costs, including financing and acquisition costs, incurred in
connection with the abandonment of EXCO's proposed acquisition of Taurus Energy
Corp.

         Net Income (Loss). Net loss for the fiscal year ended December 31, 1996
was $326,000, or $.85 per share, compared to a loss of $160,000, or $.47 per
share, for the nine month transition period ended December 31, 1995. This
$166,000 decrease was primarily the result of an increase in revenues being
partially offset by an increase in expenses as more fully described above.

QUASI-REORGANIZATION

   
         Effective December 31, 1997, EXCO effected a quasi-reorganization
through the application of $8,799,000 of its additional paid-in capital account
to eliminate its accumulated deficit. EXCO's Board of Directors decided to
effect a quasi-reorganization given the change in management in December 1997,
the infusion of new equity capital in December 1997 and an expected increase in
acquisition, exploitation and development activities. Based on these factors and
establishment of a strategic growth plan, EXCO's Board of Directors and
management believed that the reflection of prior losses on EXCO's balance sheet
would not be meaningful in presenting the financial position
    

                                       36

<PAGE>   39


of EXCO. EXCO's accumulated deficit was primarily related to past operations and
properties that have been disposed of; the accumulated deficit was not, in
management's view, reflective of EXCO's current financial condition. The
historical carrying values of EXCO's assets and liabilities of EXCO were not
adjusted in connection with the quasi-reorganization.

CHANGE IN METHOD OF ACCOUNTING FOR OIL AND NATURAL GAS OPERATIONS

         In the fourth quarter of 1997, EXCO changed from the successful efforts
method to the full cost method of accounting for its oil and natural gas
operations. All prior year's financial statements presented herein have been
restated to reflect the change.

         During the past ten years, EXCO has incurred minimal exploration and
acquisition costs, has liquidated substantially all its properties and completed
"out of court" debt restructurings. Recently there was a change in control of
ownership of EXCO and new management was appointed. New management views EXCO as
a new company and believes the past operations are insignificant and not
relevant to EXCO's future plans.

         New management believes that the change in accounting for oil and
natural gas properties is to a preferable method because the full cost method
will more appropriately reflect EXCO's future operations which will result from
the significant management changes at EXCO. Further, new management does not
believe that the use of the successful efforts method of accounting is
appropriate for a small to medium size acquisition, development and exploitation
company.

LIQUIDITY AND CAPITAL RESOURCES

         GENERAL

   
         EXCO's working capital on March 31, 1998 was a negative $116,000
compared to a positive $399,000 on December 31, 1997. This $515,000 decrease in
working capital resulted primarily from the purchase of the Maverick County
Properties and an increase in general and administrative expenses. EXCO's
working capital on December 31, 1997 was $399,000 compared to a negative
$285,000 on December 31, 1996. This $684,000 increase in working capital
resulted primarily from the sale of Common Stock to two individuals in 1997 for
net proceeds of $600,000. In addition, EXCO sold certain non-strategic oil and
natural gas properties in 1997 in order to generate working capital. EXCO's
working capital on December 31, 1996 was a negative $285,000 compared to a
negative $279,000 on December 31, 1995. This $6,000 decrease in working capital
resulted from the utilization of EXCO funds for the costs associated with the
attempted acquisition of Taurus Energy Corp. being partially offset by the
capital received upon the exercise of a stock option to purchase 120,000 shares
of Common Stock by a director of EXCO during the first quarter of 1996. The
option exercise resulted in $225,000 in cash for EXCO. This addition to working
capital was utilized primarily to pay off EXCO's short-term note payable in the
second quarter of 1996.
    

   
         EXCO estimates that, on a pro forma basis, capital expenditures of
approximately $1,150,000 for drilling and recompletions may be necessary to
bring the nonproducing reserves, to proved developed producing status. The costs
may change due to adjustments to the completion plans and inflation. If these
reserves are not developed, future cash flows may be negatively impacted,
resulting in a reduction in working capital and liquidity. No contractual
obligations exist that require EXCO to make any of these capital expenditures.
EXCO expects to use cash available from working capital or borrowings under the
Credit Facility to fund such expenditures if and when made.
    

         LONG-TERM DEBT

   
         On March 31, 1998, EXCO had long-term debt (excluding current
maturities) of $612,000. EXCO's $150,000 note payable on December 31, 1996 was
paid in full in the second quarter of 1997 through the proceeds received from
the sale of an oil and natural gas property. This note payable amount had been
borrowed from a bank to fund the costs associated with the attempted acquisition
of Taurus Energy Corp.
    


                                       37

<PAGE>   40
         SALE OF EQUITY

   
         On December 31, 1997, Messrs. Eubank and Ellis purchased 200,000 shares
(100,000 shares each) of EXCO's Common Stock, par value $.01 per share, for
$3.00 per share, thus generating $600,000 in cash for EXCO. These proceeds were
primarily used for working capital and general corporate purposes.
    

         NEW CREDIT FACILITY

         On February 11, 1998, EXCO entered into the Credit Facility. The Credit
Facility provides for borrowings up to $50 million, subject to borrowing base
limitations.

   
         The Credit Facility consists of a regular revolver which on May 15,
1998, had a borrowing base of $3.5 million. On May 15, 1998, approximately
$1,327,500 was available to be borrowed under the Credit Facility. A portion of
the borrowing base is available for the issuance of letters of credit. All
borrowings under the Credit Facility are secured by a first lien deed of trust
providing a security interest in tangible and intangible assets representing at
least 90% of the assessed present value of EXCO's oil and natural gas
properties.

         The Credit Facility provides that if EXCO's aggregate outstanding
indebtedness is less than $5,000,000, advances will bear interest at 1.5% over
the appropriate LIBOR rate. If the aggregate outstanding indebtedness is
greater than $5,000,000, then advances will bear interest at 1.0% over LIBOR if
the borrowing base usage is less than 50%, 1.25% over LIBOR if the borrowing
base usage is between 50-70%, 1.5% over LIBOR if the borrowing base usage is
between 70-90%, and 1.75% over LIBOR if the borrowing base usage exceeds 90%.
Currently, EXCO's interest rate under the Credit Facility is 7.2% per annum.
The Credit Facility also permits EXCO to repay and reborrow amounts under the
Credit Facility without any penalty, thereby allowing EXCO the flexibility to
utilize any available cash to reduce its outstanding indebtedness and thus, its
costs of borrowed funds.

         Under the terms of the Credit Facility, EXCO must not permit its
Current Ratio (as defined) of Consolidated Current Assets (as defined) to its
Consolidated Current Liabilities (as defined) to be less than 1.0 to 1.0 at any
time. Furthermore, EXCO must not permit its Consolidated Tangible Net Worth (as
defined) to be less than $500,000 at any time between February 11, 1998 and
March 31, 1999. In addition, by March 31, 1999, EXCO's Consolidated Tangible Net
Worth must increase by 50% of EXCO's Consolidated Net Income (as defined) for
the fiscal quarter then ended and for every fiscal quarter thereafter must
increase by 50% of EXCO's Consolidated Net Income for the fiscal quarter then
ended. On December 31, 1997, if the Credit Facility had been outstanding at that
time, EXCO would have been in compliance with both the Current Ratio and the
Consolidated Tangible Net Worth covenants. On March 31, 1998, EXCO was in
compliance with the Consolidated Tangible Net Worth covenant, but was not in
compliance with the Current Ratio covenant. On May 15, 1998, NationsBank waived
EXCO's noncompliance with the Current Ratio at March 31, 1998. On May 15, 1998,
EXCO was in compliance with both the Current Ratio and the Consolidated Tangible
Net Worth covenants. EXCO believes, but cannot assure, that it will be able to
comply with all restrictive covenants in the future.
    

         No principal amortization shall be required during the Credit Facility
period as long as the aggregate principal balance does not exceed the borrowing
base then in effect. However, if a borrowing base deficiency exists after giving
effect to the redetermination, then EXCO must either (a) eliminate such
borrowing base deficiency by making a single mandatory prepayment of principal
on the revolving loan in an amount equal to the entire amount of such borrowing
base deficiency on the first monthly date following the date on which such
borrowing base deficiency is determined to exist, (b) eliminate such deficiency
by making 6 consecutive mandatory prepayments of principal on the revolving loan
each of which shall be in the amount of one sixth (1/6th) of the amount of such
borrowing base deficiency commencing on the first monthly date following the
date on which such borrowing base deficiency is determined to exist and
continuing on each monthly date thereafter, or (c) eliminate such borrowing base
deficiency by submitting additional mineral interests to banks on the first
monthly date following the date on which such borrowing base deficiency is
determined to exist for evaluation as borrowing base properties which banks, in
their sole discretion, determine have a value sufficient to increase the
borrowing base by at least the amount of the borrowing base deficiency. If by
the first scheduled borrowing base redetermination EXCO has not realized a
minimum of $10.0 million in additional cash equity, then, beginning July 20,
1998 and on the twentieth day of each


                                       38
<PAGE>   41
month thereafter, EXCO will be required to amortize the then outstanding debt
balance by applying 75% of the previous month's net revenues to the Credit
Facility. The Credit Facility matures on February 11, 2000.

   
         EXCO's next borrowing base redetermination is scheduled for no later
than July 1, 1998, and semi-annually thereafter. EXCO may seek additional
borrowing capacity at that time for its acquisition and exploitation strategy.
However, there is no assurance that the current strategy will result in
increased collateral values or that such values will enable EXCO to borrow the
funds needed to continue the strategy.
    

         The Credit Facility contains a number of covenants affecting EXCO's
liquidity and capital resources, including restrictions on EXCO's ability to
incur indebtedness at any time in an amount exceeding $100,000 or to pledge
assets outside of the Credit Facility, EXCO's maintenance of a minimum net worth
and restrictions on the payment of dividends on EXCO's capital stock.

         NEED TO RAISE ADDITIONAL CAPITAL

         The growth of EXCO's business will require substantial capital on a
continuing basis. There is no assurance that any such required additional funds
would be available on satisfactory terms and conditions, if at all. There is
also no assurance that EXCO will not pursue, from time to time, opportunities to
acquire oil and natural gas properties and businesses that may utilize the
capital currently expected to be available for its present operations. The
amount and timing of EXCO's future capital requirements, if any, will depend
upon a number of factors, including drilling costs, transportation costs,
equipment costs, marketing expenses, staffing levels and competitive conditions,
and any purchases or dispositions of assets, many of which are not within EXCO's
control. Failure to obtain any required additional financing could materially
affect the growth, cash flow and earnings of EXCO. In addition, EXCO's pursuit
of additional capital could result in the incurrence of additional debt or
potentially dilutive issuances of additional equity securities.

INFLATION AND CHANGING PRICES

         The impact of inflation, as always, is difficult to assess. In 1997 and
through the first quarter of 1998, EXCO has experienced a weakness in prices
received for its oil and natural gas production. EXCO cannot anticipate whether
the present level of inflation will remain, however, a sudden increase in
inflation and/or an increase in operating costs or drilling costs coupled with a
continuation of low oil prices could have an adverse effect on the operations of
EXCO.

YEAR 2000 COMPLIANCE

         EXCO's management has conducted a review of its information systems and
related data-processing activities to assess its exposure to the Year 2000
issue. As a result, EXCO recently purchased an oil and natural gas based
software system which is Year 2000 compliant. The Year 2000 compliant version of
this software is in use at other oil and natural gas companies currently. EXCO
expects this software to be installed and operational on or before May 31, 1998.

         EXCO currently uses Year 2000 compliant engineering evaluation software
for acquisition analysis, as well as internal engineering applications. EXCO's
spreadsheet and word processing software is also Year 2000 compliant.

         EXCO has potential Year 2000 exposure with regard to its third party
relationships and services including its bank and bank accounts, payroll
processing which is outsourced and other vendor and/or service providers who
utilize computers. Though EXCO has no control over Year 2000 compliance
implementation by these parties, EXCO has inquired and been assured that all of
EXCO's service providers are currently or will be Year 2000 compliant.

   
         EXCO does not currently anticipate that it will incur material
expenditures, if any at all, to complete modifications for the Year 2000.

                             BUSINESS AND PROPERTIES

GENERAL

   
         EXCO is an independent oil and natural gas company that has been
engaged in the oil and natural gas business since 1955. EXCO's activities are
currently conducted primarily in Texas and Louisiana. Due to limited capital
resources and cash flow, in recent years EXCO's business activity has decreased.
At December 31, 1997, EXCO had 779,150 Boe of proved reserves, 93% of which were
natural gas, and owned leasehold interests in a total of 15,788 gross (3,744
net) acres of oil and natural gas properties, 49% of gross acres (75% net) which
were developed acres. EXCO held interests in 47 gross (9.76 net) wells at
December 31, 1997. On a pro forma basis at December 31, 1997, EXCO had an 
interest in 176 gross (49.0 net) wells and had estimated  proved reserves of
1,965,500 Boe with an estimated SEC PV-10 of $10.2 million. Approximately 65% of
these reserves were classified as  proved developed producing reserves. On a pro
forma basis at December 31, 1997, EXCO's Proved Reserves had an estimated 
reserve life of 13.6 years and were 70% natural gas. EXCO currently serves as
operator for approximately 66 wells. See "Business and Properties--Oil and
Natural Gas Reserves" and "Acreage."

    

         On December 19, 1997, Mr. Miller acquired 413,423 (approximately 51%)
of EXCO's outstanding shares of Common Stock at $3.00 per share, from various
holders, including certain current and former officers and directors of EXCO. At
that time, three of EXCO's five directors resigned and Mr. Miller and Mr. Eubank
were elected to the Board of Directors. In addition, Mr. Miller was elected
Chairman of the Board and Chief Executive Officer and Mr. Eubank was elected
President, Treasurer and Chief Financial Officer. On December 31, 1997, Mr.
Eubank and Mr. Ellis each acquired from EXCO 100,000 shares of Common Stock at
$3.00 per share. Also, on December 31, 1997, Mr. Eubank resigned as Chief
Financial Officer and Dr. Ramsey was appointed Chief Financial Officer of EXCO.
Mr. Miller was formerly Chairman of the Board and Chief Executive Officer of
Coda. Mr. Eubank was formerly President and a director of Coda and Mr. Ellis was
formerly a director of Coda. Dr. Ramsey was formerly Financial Planning Manager.
With the proceeds of the Rights Offering and the Credit Facility, the new
management team intends to commence an aggressive acquisition, development and
exploitation program. In executing this strategy, EXCO will focus on producing
properties with enhancement opportunities from activities such as infill
drilling, recompletions, repairs and equipment changes. EXCO will seek
properties it can operate, thus maintaining the maximum control of enhancement
activities. EXCO intends to generate drilling prospects internally and acquire
prospects from independent geologists and geophysicists and other oil and
natural gas operators.

BUSINESS STRATEGY

         Following the Rights Offering, EXCO's business strategy will be to
enhance shareholder value through increases in revenues, earnings and operating
cash flow achieved through expansion and diversification of its energy
operations. EXCO intends to pursue a strategy of asset, revenue and cash flow
growth through acquisitions and development and exploitation of proved oil and
natural gas properties. EXCO believes there are numerous opportunities to
acquire additional energy assets and to enhance the value of such assets. EXCO's
current management successfully executed this strategy while at Coda. EXCO will
pursue its strategy of asset, revenue and cash flow growth in the following
primary areas:

         o        Growth. Achieve asset, revenue and cash flow growth as a
                  result of the acquisition and further development of other
                  producing oil and natural gas properties. EXCO believes there
                  are numerous opportunities to acquire additional energy assets
                  and to enhance the value of such assets through improved
                  operating practices and by aggressively developing reserve
                  potential.

         o        Acquire and Enhance Producing Oil and Natural Gas Properties.
                  EXCO intends to take advantage of opportunities that currently
                  exist in the United States to acquire producing oil and
                  natural gas properties. EXCO plans to continue to focus its
                  acquisition activities onshore in Texas, New Mexico, Oklahoma
                  and Louisiana to complement its existing properties and
                  operations; however, EXCO plans to review potential
                  acquisitions in other geographical regions of the United
                  States if


                                       40
<PAGE>   43
                  they represent a significant concentration of energy-related
                  assets. EXCO will target producing properties that management
                  believes have additional development and exploitation
                  potential.

   
         o        Emphasize Exploitation and Development Activities. EXCO plans
                  to exploit its existing oil and natural gas properties and to
                  conduct development evaluation and drilling on its existing
                  and future oil and natural gas properties. EXCO intends to
                  concentrate on enhancement opportunities from activities such
                  as infill drilling, recompletions, repairs and equipment
                  changes. EXCO may participate, from time to time, in a limited
                  number of exploratory wells.
    

         o        Corporate Efficiencies. EXCO intends to develop and operate a
                  larger asset base with less than proportionate increases in
                  its overhead, which will enable EXCO to achieve and maintain a
                  competitive cost structure.

         o        Capital Management. EXCO is committed to maintaining financial
                  strength and flexibility to position itself to pursue
                  opportunities for business expansion and acquisitions and to
                  permit EXCO to adapt to down cycles in the energy industry.
                  EXCO believes that effective management of its debt and equity
                  are key to achieving this objective.

   
         o        Technology. EXCO is increasing its exploitation efforts,
                  focusing on established geological trends where EXCO can
                  employ geological, geophysical and engineering expertise. EXCO
                  is considering the application of 3-D seismic and advanced
                  drilling technologies where cost-effective and appropriate.
    

EXPLOITATION AND DEVELOPMENT ACTIVITIES

         Historically, EXCO has financed its exploitation and development
expenditures primarily through cash flow from operations, bank borrowings,
equity capital from private sales of stock and promoted funds from industry
partners. With respect to its acquisition activities, EXCO intends to shift its
emphasis to larger scale acquisitions of producing properties with additional
development and exploitation potential. Initially, EXCO plans to use a
combination of debt and equity financing to fund these larger acquisitions.

         EXCO made exploitation and development expenditures of $108,000,
$17,000 and $74,000 during the nine month transition period ended December 31,
1995, the fiscal year ended December 31, 1996 and the fiscal year ended December
31, 1997, respectively. EXCO made net lease acquisition expenditures of $4,000,
$1,000 and $2,000 during the nine month transition period ended December 31,
1995, the fiscal year ended December 31, 1996 and the fiscal year ended December
31, 1997, respectively. EXCO's ability to continue to fund its exploitation and
development activities depends upon cash flow and its ability to secure the
necessary financing for such activities.

OPERATING ACTIVITIES

         Where possible, EXCO prefers to act as operator of the oil and natural
gas properties and prospects in which it owns an interest. The operator of an
oil and natural gas property supervises production, maintains production
records, employs field personnel and performs other functions required in the
production and administration of such property. The fees for such services
customarily vary from well to well, depending on the nature, depth and location
of the well being operated. Generally, the operator of an oil and natural gas
prospect is determined by such factors as the size of the working interest held
by a participant in the prospect, a participant's knowledge and experience in
the geological area in which the prospect is located and geographical
considerations. On December 31, 1997, EXCO was the operator of 24 gross (7.92
net) wells, which represented approximately 51.1% of the gross wells and 81.1%
of the net wells in which EXCO had an interest at such date. The remainder of
the wells in which EXCO had an interest at such date are operated by third party
operators. The wells that EXCO operates are located in Texas and Louisiana.
Although EXCO elects to operate and manage most of its properties and drilling
activities, its wells are drilled by independent drilling contractors.

         LOGANSPORT FIELD

         In 1995, EXCO acquired an additional 48% working interest in, and
became the operator of, an existing natural gas well (the "Acquired Well") in
the Logansport field located in DeSoto Parish, Louisiana. As a result of
acquisitions, EXCO owns a 51% working interest in the Acquired Well and related
acreage. The Logansport field produces from a series of low permeability
reservoirs with long life natural gas reserves. EXCO's reserves are produced in
the Hosston (Travis Peak) and Pettit formations from depths between 6,000 and
7,200 feet. The field is developed with 640 and 320 acre spacing, and wells in
the field are expected to have a production life exceeding 30 years.

         NINE MILE DRAW FIELD

         The Nine Mile Draw field is located in Reeves County, Texas, and
production is derived from a low permeability fractured limestone formation.
Presently, EXCO operates 1 gross (.61 net) well in the Fusselman formation,
which produces from depths between 13,700 and 14,400 feet and is estimated to
have a remaining reserve life of approximately 20 years.

         SOUTHERN PINE FIELD

         EXCO owns a nonoperated interest in 1 gross (.12 net) well in Cherokee
County, Texas. Production is derived from the Travis Peak formation, which has
estimated net reserves of approximately 152,453 Mcf of natural gas. Reserve
estimates indicate that as of December 31, 1997 the SEC PV-10 value attributable
to EXCO's interest was approximately $130,615.

TITLE TO PROPERTIES

         As is common industry practice, little or no investigation of title is
made at the time of acquisition of undeveloped properties, other than a
preliminary review of local mineral records. Title investigations are made, and
in most cases, a title opinion of local counsel is obtained before commencement
of drilling operations. EXCO believes that the methods it utilizes for
investigating title prior to the acquisition of any properties are consistent
with practices customary in the oil and natural gas industry and that such
practices are adequately designed to enable EXCO to acquire good title to such
properties. Some title risks, however, cannot be avoided, despite the use of
customary industry practices.

         EXCO's properties are generally subject to customary royalty and
overriding royalty interests, liens incident to operating agreements, liens for
current taxes and other burdens and minor encumbrances, easements and
restrictions, and may be mortgaged to secure indebtedness of EXCO. EXCO believes
that none of these burdens


                                       42
<PAGE>   45
either materially detract from the value of such properties or materially
interfere with their use in the operation of EXCO's business. Substantially all
of EXCO's properties are pledged as collateral under the Credit Facility.

OIL AND NATURAL GAS RESERVES

         All reserves are evaluated at contract temperature and pressure which
can affect the measurement of natural gas reserves. Operating costs, development
costs and certain production-related and ad valorem taxes were deducted in
arriving at the estimated future net cash flows. No provisions were made for
income taxes. The following estimates set forth reserves considered to be
economically recoverable under normal operating methods and existing conditions
at the prices and operating costs prevailing at the dates indicated above. The
estimates of the SEC PV-10 from future net cash flows differ from the
standardized measure of discounted future net cash flows set forth in the notes
to the Financial Statements of EXCO, which is calculated after provision for
future income taxes. There can be no assurance that these estimates are accurate
predictions of future net cash flows from oil and natural gas reserves or their
present value.

         Proved reserves are estimates of oil and natural gas to be recovered in
the future. Reservoir engineering is a subjective process of estimating the
sizes of underground accumulations of oil and natural gas that cannot be
measured in an exact way. The accuracy of any reserve estimates is a function of
the quality of available data and of engineering and geological interpretation
and judgment. Reserve reports of other engineers might differ from the reports
contained herein. Results of drilling, testing and production subsequent to the
date of the estimate may justify revision of such estimate. Future prices
received for the sale of oil and natural gas may be different from those used in
preparing these reports. The amounts and timing of future operating and
development costs may also differ from those used. Accordingly, reserve
estimates are often different from the quantities of oil and natural gas that
are ultimately recovered. See "Risk Factors -- Uncertainty of Estimates of
Reserves and Future Net Cash Flows."

         On December 31, 1997, EXCO's oil and natural gas reserves included
direct working interests in 47 wells in the states of Texas, Louisiana, North
Dakota, Kansas and Oklahoma, as well as overriding royalties in an additional
nine wells in Texas. EXCO has no reserves offshore or outside of the United
States. On December 31, 1997, approximately 61% of the present value of the
estimated future net revenues attributable to EXCO's properties were
attributable to proved developed reserves and approximately 39% was attributable
to proved undeveloped reserves. In addition, approximately 7.5% of the proved
reserves were attributable to oil and approximately 92.5% were attributable to
natural gas, on a Boe basis.

         The following table summarizes EXCO's proved reserves on December 31,
1997, and was prepared in accordance with the rules and regulations of the
Commission:

         A significant portion of the value of the proved nonproducing reserves
are in the Logansport and the Nine Mile Draw fields. There are risks associated
with recovery of reserves in the nonproducing category. In addition, EXCO must
incur certain costs and undertake certain risks associated with drilling and
workover operations to recover these reserves.

         The reserve estimates presented as of December 31, 1997 have been
prepared by Lee Keeling and Associates, Inc., independent petroleum engineers,
Tulsa, Oklahoma, and are a part of their report on EXCO's oil and natural gas
properties. Estimates of oil and natural gas reserves are, of necessity,
projections based on engineering data and, thus, are forward-looking in nature.
However, because of the uncertainties inherent in the interpretation of such
data, EXCO cannot ensure that the reserves set forth herein will ultimately be
realized and the actual results could differ materially. See Note 11 to EXCO's
Financial Statements herein for additional information regarding EXCO's oil and
natural gas reserves, including the present value of future net revenues.
Previous reserve estimates as of March 31, 1995 reported herein were prepared by
Milmac Operating Company, independent petroleum engineers, Lubbock, Texas.

</TABLE>

    
         Total oil and natural gas reserves for the fiscal year ended December
31, 1997 decreased 23% from the prior fiscal year primarily due to decreases in
production volumes resulting from the sale in 1997 of certain properties and the
normal depletion of producing wells. The average sales price per barrel of oil
decreased $.86, or 4%, and the average sale price per Mcf of natural gas
increased $.27, or 14%, from such prices for fiscal year end December 31, 1996.

         Total oil and natural gas revenues for the fiscal year ended December
31, 1996 increased 56% from the nine month transition period ended December 31,
1995 due to both an increase in oil and natural gas prices and an increase in
production volumes, resulting largely from the 3 month longer time period of
fiscal 1996. The average sales price per barrel of oil increased $3.93, or 24%,
and the average sales price per Mcf of natural gas increased $.47, or 34%, from
such prices for the nine month transition period ended December 31, 1995.

         EXCO's net production reported in the preceding table only includes
production that is owned by EXCO and produced to its oil and natural gas
interest, less royalties. Oil production for the fiscal year ended December 31,
1997 was 35% lower and natural gas production was 19% lower than for the fiscal
year ended December 31, 1996. Oil production for the fiscal year ended December
31, 1996 was 16% higher and natural gas production was 24%


                                       44

higher than the nine month transition period ended December 31, 1995. On a Boe
basis total production for the fiscal year ended December 31, 1996 decreased 25%
from the fiscal year ended December 31, 1996 and total production for the fiscal
year ended December 31, 1996 increased 22% from the nine month transition period

DRILLING ACTIVITIES

         With respect to its drilling operations, EXCO plans to concentrate on
lower risk, development-type properties, generally consisting of drilling to
reservoirs from which production is or formerly was being obtained. The drilling
of development wells is subject to the normal risk of dry holes, or a failure to
produce oil and natural gas in commercial quantities. The degree of risk varies
depending, among other things, on the distance between the well and the nearest
producing well, other available geological information and the geological
features of the area. In the past, EXCO has drilled higher risk, 
exploratory-type wells, primarily in geological basins with relatively high
levels of drilling density and where adequate subsurface information in the form
of well logs and seismic data was generally available to evaluate potential
hydrocarbon accumulations. All drilling activities are subject to the risk of
encountering unusual or unexpected formations and pressures and other conditions
that may result in financial losses or liabilities to third parties or
governmental entities, many of which may not be covered by insurance. The number
and type of wells drilled by EXCO will vary depending on the amount of funds
available for drilling, the cost of each well, the size of the fractional
working interests acquired by EXCO in each well and the estimated recoverable
reserves attributable to each well.

         The number of wells drilled refers to the number of wells (holes)
completed at any time during the fiscal year, regardless of when drilling was
initiated. All drilling activities referenced in the above tables were conducted
in the State of Texas. In April 1998, EXCO drilled and completed one development
well in Maverick County, Texas.
    

ACREAGE

         The following table sets forth EXCO's interest in developed acreage and
undeveloped acreage on December 31, 1997:

</TABLE>


         The primary terms of the oil and natural gas leases covering the
majority of EXCO's undeveloped acreage expire at various dates, generally
ranging from 1 to 5 years. EXCO can retain its interest in undeveloped acreage
by drilling activity that establishes commercial reserves sufficient to maintain
the lease. Certain of EXCO's undeveloped acreage in Texas is being "held by
production," for which expiration will not occur until production ceases from
all wells on the particular leases.

SALES OF PRODUCING PROPERTIES AND UNDEVELOPED ACREAGE

         EXCO evaluates properties on an ongoing basis to determine the economic
viability of the property and whether such property enhances the objectives of
EXCO. During the course of normal business, EXCO may dispose of producing
properties and undeveloped acreage if EXCO believes that such disposition is in
its best interests.

         In the fiscal year ended December 31, 1997, EXCO sold its interest in 3
major groups of producing oil properties in Texas and Illinois for a total of
$270,000 which reduced the full cost pool accordingly. In the fiscal year ended
December 31, 1996, EXCO exchanged its interest in 4 non-operated producing wells
for an interest in each of the 4 operated producing wells. In the nine month
transition period ended December 31, 1995, EXCO sold a portion of its interest
in an undeveloped lease, which reduced EXCO's basis in the lease by $28,000.

PRODUCTS, MARKETS AND REVENUES

         Oil and natural gas are the principal products currently produced by
EXCO. EXCO does not refine or process the oil and natural gas that it produces.
EXCO sells the oil it produces under short-term contracts at market prices in
the areas in which the producing properties are located, generally at F.O.B.
field prices posted by the principal purchase of oil in such areas.

         Natural gas produced from EXCO's properties is sold under both
short-term and long-term contracts to transmission and utility companies that
have pipelines in the vicinity of the producing properties or that will
construct pipelines to such properties. The contracts are of a type common
within the industry, and a separate contract is usually negotiated for each
property. Typically, EXCO's sales contracts are made for terms ranging from
day-to-day up to 6 months.

         The availability of a ready market for oil and natural gas and the
prices of oil and natural gas are dependent upon a number of factors that are
beyond the control of EXCO. These factors include, among other things, the level


                                       46

<PAGE>   49
of domestic production and economic activity generally, the availability of
imported oil and natural gas, actions taken by foreign oil producing nations,
the availability of natural gas pipelines with adequate capacity and other
transportation facilities, the availability and marketing of other competitive
fuels, fluctuating and seasonal demand for oil, natural gas and refined products
and the extent of governmental regulation and taxation (under both present and
future legislation) of the production, refining, transportation, pricing, use
and allocation of oil, natural gas, refined products and substitute fuels.
Accordingly, in view of the many uncertainties affecting the supply and demand
for oil, natural gas and refined petroleum products, it is not possible to
predict accurately the prices or marketability of the oil and natural gas from
any producing well in which EXCO has or may acquire an interest.

         Oil prices have been subject to significant fluctuations over the past
decade. Levels of production maintained by the Organization of Petroleum
Exporting Companies ("OPEC") member nations and other major oil producing
countries are expected to continue to be a major determinant of oil price
movements in the future. As a result, future oil price movements cannot be
predicted with any certainty. Similarly, during the past several years, the
market price for natural gas has been subject to significant fluctuations on a
monthly basis, as well as from year to year. These frequent changes in the
market price make it impossible for EXCO to predict natural gas price movements
with any certainty.

         EXCO cannot provide assurance that it will be able to market all oil or
natural gas that EXCO produces or, if such oil or natural gas can be marketed,
that favorable price and contractual terms can be negotiated. Changes in oil and
natural gas prices may significantly affect the revenues and cash flow of EXCO
and the value of its oil and natural gas properties. Further, significant
declines in the prices of oil and natural gas may have a material adverse effect
on the business and financial condition of EXCO. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Results of
Operations."

         In certain areas in which EXCO engaged in oil and natural gas
production activities, the supply of oil and natural gas available for delivery
from time to time exceeds the demand. During such times, companies purchasing
oil and natural gas in such areas reduce the amount of oil and natural gas that
they will purchase or "take." If buyers cannot be readily located for newly
discovered oil and natural gas reserves, newly completed oil and natural gas
wells may be shut-in for various periods of time. As a result, the over-supply
of oil and natural gas in certain areas may cause EXCO to experience "take"
problems or may adversely affect EXCO's ability to obtain contracts to market
oil and natural gas discovered in wells in which EXCO owns an interest.

         The following table sets forth the amount of EXCO's oil sales, natural
gas sales and the percent of oil and natural gas sales to total revenues for the
periods indicated:

</TABLE>


         In February 1996, EXCO changed its fiscal year from a March 31 year end
to a December 31 year end, resulting in a short year of 9 months for the
transition period ended December 31, 1995. The comparability of most of the year
to year comparisons in this report is affected by the fact that the nine month
transition period ended December 31, 1995 is 3 months shorter than the full
fiscal years ended December 31, 1996 and December 31, 1997.

DELIVERY COMMITMENTS

         EXCO is not presently obligated to provide a fixed and determinable
quantity of oil or natural gas under any existing contract or agreement.


                                       47

CUSTOMERS

         During the fiscal year ended December 31, 1997, sales of oil and
natural gas to three purchasers, Scurlock Permian Corporation, Delhi Gas
Pipeline Corporation and Aurora Natural Gas, L.L.C., accounted for 22%, 19%, and
14%, respectively, of EXCO's total revenues. During the fiscal year ended
December 31, 1996, sales of oil and natural gas to two purchasers, Scurlock
Permian Corporation and Delhi Gas Marketing Corp., accounted for 26% and 15%,
respectively, of EXCO's total revenues. During the nine month period ended
December 31, 1995, sales of oil and natural gas to three purchasers, Scurlock
Permian Corporation, Delhi Gas Marketing Corp. and Pride Pipeline Company,
accounted for 20%, 13% and 10%, respectively, of EXCO's total revenues. Although
the loss of any one of EXCO's oil and natural gas purchasers could temporarily
cease or delay EXCO's production and sale of its oil and natural gas in the
purchasers' particular service area, EXCO believes it would be able, under
current economic circumstances, to contract with other purchasers for its oil
and natural gas production.

REGULATION

         GENERAL

         EXCO's operations are affected from time to time in varying degrees by
political developments and federal and state laws and regulations. In
particular, oil and natural gas production operations and economics are or have
been affected by price control, tax and other laws relating to the oil and
natural gas industry, by changes in such laws and by changing administrative
regulations. There are currently no price controls on oil, condensate or NGLs.
To the extent price controls remain applicable after the enactment of the
Natural Gas Wellhead Decontrol Act of 1989, EXCO is of the opinion that such
controls will not have a significant impact on the prices received by EXCO for
natural gas produced in the near future.

         Legislation affecting the oil and natural gas industry is under
constant review for amendment or expansion, frequently increasing the regulatory
burden. Also, numerous departments and agencies, both federal and state, are
authorized by statute to issue and have issued rules and regulations binding on
the oil and natural gas industry and its individual members, compliance with
which is often difficult and costly and certain of which carry substantial
penalties for the failure to comply. EXCO cannot predict how existing
regulations may be interpreted by enforcement agencies or the courts, nor
whether amendments or additional regulations will be adopted, nor what effect
such interpretations and changes may have on EXCO's business or financial
condition.

         NATURAL GAS REGULATION

   
         Historically, interstate pipeline companies generally acted as
wholesale merchants by purchasing natural gas from producers and reselling the
natural gas to local distribution companies and large end users. Commencing in
late 1985, the Federal Energy Regulatory Commission ("FERC") issued a series
of orders that have had a major impact on interstate natural gas pipeline
operations, services, and rates, and thus have significantly altered the
marketing and price of natural gas. The FERC's key rule making action, Order No.
636 ("Order 636"), issued in April 1992, required each interstate pipeline to,
among other things, "unbundle" its traditional bundled sales services and create
and make available on an open and nondiscriminatory basis numerous constituent
services (such as gathering services, storage services, firm and interruptible
transportation services, and standby sales and natural gas balancing services),
and to adopt a new rate making methodology to determine appropriate rates for
those services. To the extent the pipeline company or its sales affiliate makes
natural gas sales as a merchant in the future, it does so pursuant to private
contracts in direct competition with all other sellers, such as EXCO; however,
pipeline companies and their affiliates were not required to remain "merchants"
of natural gas, and most of the interstate pipeline companies have become
"transporters only." In subsequent orders, the FERC largely affirmed the major
features of Order 636 and denied a stay of the implementation of the new rules
pending judicial review. By the end of 1994, the FERC had concluded the Order
636 restructuring proceedings, and, in general, accepted rate filings
implementing Order 636 on every major interstate pipeline. However, even through
the implementation of Order 636 on individual interstate pipelines is
essentially complete, many of the individual pipeline restructuring proceedings,
as well as Order 636 itself and the regulations promulgated thereunder, are
subject to pending appellate review and could possibly be changed as a result of
future court orders. EXCO cannot predict whether the FERC's orders will be
affirmed on appeal or what the effects will be on its business.
    


                                       48
<PAGE>   51
         In recent years the FERC also has pursued a number of other important
policy initiatives which could significantly affect the marketing of natural
gas. Some of the more notable of these regulatory initiatives include (i) a
series of orders in individual pipeline proceedings articulating a policy of
generally approving the voluntary divestiture of interstate pipeline owned
gathering facilities by interstate pipelines to their affiliates (the so-called
"spin down" of previously regulated gathering facilities to the pipeline's
nonregulated affiliate), (ii) the completion of a rule making involving the
regulation of pipelines with marketing affiliates under Order No. 497, (iii) the
FERC's ongoing efforts to promulgate standards for pipeline electronic bulletin
boards and electronic data exchange, (iv) a generic inquiry into the pricing of
interstate pipeline capacity, (v) efforts to refine the FERC's regulations
controlling operation of the secondary market for released pipeline capacity,
and (vi) a policy statement regarding market based rates and other
non-cost-based rates for interstate pipeline transmission and storage capacity.
Several of these initiatives are intended to enhance competition in natural gas
markets, although some, such as "spin downs," may have the adverse effect of
increasing the cost of doing business on some in the industry as a result of the
monopolization of those facilities by their new, unregulated owners. The FERC
has attempted to address some of these concerns in its orders authorizing such
"spin downs," but it remains to be seen what effect these activities will have
on access to markets and the cost to do business. As to all of these recent FERC
initiatives, the ongoing, or in some instances, preliminary evolving nature of
these regulatory initiatives makes it impossible at this time to predict their
ultimate impact on EXCO's business.

         EXCO owns, directly or indirectly, certain natural gas facilities that
it believes meet the traditional tests the FERC has used to establish a
company's status as a gatherer not subject to FERC jurisdiction under the
Natural Gas Act of 1938 (the "NGA"). Moreover, recent orders of the FERC have
been more liberal in their reliance upon or use of the traditional tests, such
that in many instances, what was once classified as "transmission" may now be
classified as "gathering." EXCO transports its own natural gas through these
facilities. EXCO also transports certain of its natural gas through gathering
facilities owned by others, including interstate pipelines. With respect to item
(i) in the preceding paragraph, on May 27, 1994, the FERC issued orders in the
context of the "spin off" or "spin down" of interstate pipeline owned gathering
facilities. A "spin off" is a FERC approved sale of such facilities to a
non-affiliate. A "spin down" is the transfer by the interstate pipeline of its
gathering facilities to an affiliate. A number of spin offs and spin downs have
been approved by the FERC and implemented. The FERC held that it retains
jurisdiction over gathering provided by interstate pipelines, but that it
generally does not have jurisdiction over pipeline gathering affiliates, except
in the event of affiliate abuse (such as actions by the affiliate undermining
open and nondiscriminatory access to the interstate pipeline). These orders
require nondiscriminatory access for all sources of supply, prohibit the tying
of pipeline transportation service to any service provided by the pipeline's
gathering affiliate, and require the new gathering company to submit a "default"
contract if a satisfactory contract cannot be mutually agreed upon by the
interstate pipeline and its existing customers. Several petitions for rehearing
of the FERC's May 27, 1994, orders were filed. On November 30, 1994, the FERC
issued a series of rehearing orders largely affirming the May 27, 1994, orders.
The FERC clarified that "default" contracts are intended to serve only as a
transition mechanism to prevent arbitrary termination of gathering service to
existing customers. Also, the FERC now requires interstate pipelines to not only
seek authority under Section 7(b) of the NGA to abandon certificated facilities,
but also to seek authority under Section 4 of the NGA to terminate service from
both certificated and uncertificated facilities. On December 31, 1994, an appeal
was filed with the U.S. Court of Appeals for the D.C. Circuit to overturn three
of the FERC's November 30, 1994, orders. EXCO cannot predict what the ultimate
effect of the FERC's orders pertaining to gathering will have on its production
and marketing, or whether the Appellate Court will affirm the FERC's orders on
these matters.

         FEDERAL TAXATION

         The federal government is continually proposing tax initiatives that
may affect the oil and natural gas industry, including EXCO. Due to the
preliminary nature of these proposals, EXCO is unable to determine what effect,
if any, the proposals would have on product demand or EXCO's results of
operations.

         STATE REGULATION

         The various states in which EXCO conducts activities regulate the
drilling, operation and production of oil and natural gas wells, such as the
method of developing new fields, spacing of wells, the prevention and clean-up
of pollution, and maximum daily production allowables based on market demand and
conservation considerations.


                                       49
<PAGE>   52
         ENVIRONMENTAL REGULATION

         EXCO's exploration, development and production of oil and natural gas,
including its operation of saltwater injection and disposal wells, are subject
to various federal, state and local environmental laws and regulations. Such
laws and regulations can increase the costs of planning, designing, installing
and operating oil and natural gas wells. EXCO's domestic activities are subject
to a variety of environmental laws and regulations, including, but not limited
to, the OPA, the Clean Water Act ("CWA"), the Comprehensive Environmental
Response, Compensation and Liability Act ("CERCLA"), the Resource Conservation
and Recovery Act ("RCRA"), the Clean Air Act ("CAA") and the Safe Drinking Water
Act ("SDWA"), as well as state regulations promulgated under comparable state
statutes. EXCO also is subject to regulations governing the handling,
transportation, storage and disposal of naturally occurring radioactive
materials that are found in its oil and natural gas operations. Civil and
criminal fines and penalties may be imposed for non-compliance with these
environmental laws and regulations. Additionally, these laws and regulations
require the acquisition of permits or other governmental authorizations before
undertaking certain activities, limit or prohibit other activities because of
protected areas or species and impose substantial liabilities for cleanup of
pollution.

         Under the OPA, a release of oil into water or other areas designated by
the statue could result in EXCO being held responsible for the costs of
remediating such a release, certain OPA specified damages and natural resource
damages. The extent of that liability could be extensive, as set forth in the
statute, depending on the nature of the release. A release of oil in harmful
quantities or other materials into water or other specified areas could also
result in EXCO being held responsible under the CWA for the cost of remediation,
and civil and criminal fines and penalties.

         CERCLA and comparable state statutes, also known as "Superfund" laws,
can impose joint and several and retroactive liability, without regard to fault
or the legality of the original conduct, on certain classes of persons for the
release of a "hazardous substance" into the environment. In practice, cleanup
costs are usually allocated among various responsible parties. Potentially
liable parties include site owners or operators, past owners or operators under
certain conditions and entities that arrange for the disposal or treatment of,
or transport hazardous substances found at the site. Although CERCLA, as
amended, currently exempts petroleum, including, but not limited to, crude oil,
natural gas and natural gas liquids from the definition of hazardous substance,
EXCO's operations may involve the use or handling of other materials that may be
classified as hazardous substances under CERCLA. Furthermore, there can be no
assurance that the exemption will be preserved in future amendments of the act,
if any.

         RCRA and comparable state and local requirements impose standards for
the management, including treatment, storage and disposal of both hazardous and
nonhazardous solid wastes. EXCO generates hazardous and nonhazardous solid waste
in connection with its routine operations. From time to time, proposals have
been made that would reclassify certain oil and natural gas wastes, including
wastes generated during pipeline, drilling and production operations, as
"hazardous wastes" under RCRA which would make such solid wastes subject to must
more stringent handling, transportation, storage, disposal and clean-up
requirements. This development could have a significant impact on EXCO's
operating costs. While state laws vary on this issue, state initiatives to
further regulate oil and natural gas wastes could have a similar impact.

         Because oil and natural gas exploration and production, and possibly
other activities, have been conducted at some of EXCO's properties by previous
owners and operators, materials from these operations remain on some of the
properties and in some instances require remediation. In addition, EXCO has
agreed to indemnify Sellers of producing properties from whom EXCO has acquired
reserves against certain liabilities for environmental claims associated with
such properties. While EXCO does not believe the costs to be incurred by EXCO
for compliance and remediating previously or currently owned or operated
properties will be material, there can be no guarantee that such costs will not
result in material expenditures.

         Additionally, in the course of EXCO's routine oil and natural gas
operations, surface spills and leaks, including casing leaks, of oil or other
materials occur, and EXCO incurs costs for waste handling and environmental
compliance. Moreover, EXCO is able to control directly the operations of only
those wells for which it acts as the operator. Notwithstanding EXCO's lack of
control over wells owned by EXCO but operated by others, the failure


                                       50

<PAGE>   53

of the operator to comply with applicable environmental regulations may, in
certain circumstances, be attributable to EXCO.

         It is not anticipated that EXCO will be required in the near future to
expend amounts that are material in relation to its total capital expenditures
program by reason of environmental laws and regulations, but inasmuch as such
laws and regulations are frequently changed, EXCO is unable to predict the
ultimate cost of compliance. There can be no assurance that more stringent laws
and regulations protecting the environment will not be adopted or that EXCO will
not otherwise incur material expenses in connection with environmental laws and
regulations in the future. See "Risk Factors -- Governmental Regulation."

         OTHER PROPOSED LEGISLATION

         In the past, Congress has been very active in the area of natural gas
regulation. Legislative proposals are pending in various states which, if
enacted, could significantly affect the petroleum industry. EXCO cannot predict
which proposals, if any, may actually be enacted by Congress or any of the state
legislatures, and what impact, if any, such proposals may have on EXCO's
operations.

COMPETITION

         The oil and natural gas industry is highly competitive. EXCO encounters
strong competition from other independent operators and from major oil companies
in acquiring properties in contracting for drilling equipment and in securing
trained personnel. Many of these competitors have financial resources and staffs
substantially larger than those available to EXCO.

         Exploitation for and production of oil and natural gas is also affected
by competition for drilling rigs and the availability of tubular goods and
certain other equipment. While the oil and natural gas industry has experienced
shortages of drilling rigs and equipment, pipe and personnel in the past, EXCO
is not presently experiencing any shortages and does not foresee any such
shortages in the near future. EXCO is unable to predict how long current market
conditions will continue.

         Competition for attractive oil and natural gas producing properties,
undeveloped leases and drilling rights is also strong, and EXCO cannot provide
assurance that it will be able to compete satisfactorily in the acquisition of
such properties. Many major oil companies have publicly indicated their
decisions to concentrate on overseas activities and have been actively marketing
certain of their existing producing properties for sale to independent
producers. There can be no assurance that EXCO will be successful in acquiring
any such properties.

EMPLOYEES

   
         As of May 28, 1998, EXCO employed fifteen persons of which two were
involved in field operations and thirteen were engaged in office and
administrative activities. None of EXCO's employees are represented by unions or
covered by collective bargaining agreements. To date, EXCO has not experienced
any strikes or work stoppages due to labor problems and considers its relations
with its employees to be good. EXCO also utilizes the services of independent
consultants on a contract basis.
    

PROPERTIES

         EXCO currently leases 2,000 square feet of office space in Dallas, 
Texas which is used as EXCO's headquarters.  The lease expires in December, 
1999, and provides for monthly rental payments of $6,440 plus a CPI increase in
year two. EXCO also maintains a field office in Tyler, Texas.

LEGAL PROCEEDINGS

         EXCO is not presently party to, nor is any of its property the subject
of, any material pending legal proceedings other than routine litigation
incidental to EXCO's business.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

   
         The following discussion describes certain relationships and related
transactions between EXCO and certain officers, directors and shareholders. EXCO
believes the terms of all such transactions were on terms comparable to those
that could have been negotiated with an unaffiliated third-party. Any future
transactions with officers, directors or 5% shareholders will be on terms no
less favorable to EXCO than could be obtained from third parties.
    

         MILLER SHARE PURCHASE TRANSACTION

         On December 19, 1997, Mr. Miller purchased (the "Purchase") 413,423
shares of Common Stock of EXCO, par value $.01 per share, for $3.00 per share.
Upon completion of the Purchase, Mr. Miller was at that date the beneficial
owner of approximately 51% of the Common Stock of EXCO.

         The Purchase was effected pursuant to the terms of a Stock Option
Agreement first dated December 8, 1997 among Mr. Miller, on the one hand, and
Richard D. Collins, Dave Fitzgerald, Inc., David N. Fitzgerald, Francis C.
Fitzgerald, W.R. Granberry, Glenn L. Seitz, Suzanne F. Bobo, J.A. Dinger, John
A. Schlensker, Donald C. Thomas, Jr. and R. Scott Collins (collectively, the
"Sellers"), on the other (the "Option Agreement"). The Sellers included
directors of EXCO and members of EXCO's management and certain affiliates.

         On December 18, 1997, Mr. Miller exercised his option to purchase the
shares. On December 19, 1997, Mr. Miller executed a Stock Purchase Agreement
among Mr. Miller, on the one hand, and certain Sellers, on the other (the
"Purchase Agreement"). Pursuant to the terms of the Option Agreement and the
Purchase Agreement, the Purchase was consummated December 19, 1997. In
connection with the Purchase, Mr. Miller paid the Sellers an aggregate of
approximately $1,240,269 in cash from personal funds. The consideration paid by
Mr. Miller in connection with the Purchase was determined by arms' length
negotiations between Mr. Miller and the Sellers.

         In addition, on December 19, 1997, the Board of Directors of EXCO held
a meeting at which time the resignations of various officers and directors of
EXCO were tendered and accepted. The Board appointed Mr. Miller as a Director
and then elected him Chairman and Chief Executive Officer of EXCO. The Board
also appointed Mr. Eubank to the Board of Directors and elected him President,
Treasurer and Chief Financial Officer of EXCO. Mr. David N. Fitzgerald resigned
as Chairman of the Board of EXCO, Mr. Gleeson resigned as President and Chief
Executive Officer of EXCO, Mr. Glenn L. Seitz resigned as a Director and
Treasurer of EXCO, Mr. Richard D. Collins resigned as a Director and Secretary
of EXCO and Mr. W.R. Granberry resigned as a Director of EXCO. Richard E. Miller
was elected Secretary of EXCO. Messrs. Fitzgerald and Gleeson remained as
Directors of EXCO.

         On December 31, 1997, Mr. Eubank resigned as Chief Financial Officer
and Dr. Ramsey was appointed Chief Financial Officer and Vice President of EXCO.

         PRIVATE PLACEMENT

         On December 31, 1997, EXCO issued, in a private placement conducted
pursuant to Section 4(2) of the Securities Act of 1933, 100,000 shares of Common
Stock, par value $.01 per share, to Mr. Eubank for an aggregate purchase price
of $300,000, or $3.00 per share. In addition, on that same date EXCO issued, in
a private placement, 100,000 shares to Mr. Ellis for an aggregate purchase price
of $300,000, or $3.00 per share. The purchase price for these shares were based
on the purchase price paid by Mr. Miller for his shares in the Purchase. All of
the shares so issued are deemed "restricted" shares under the Federal securities
laws. The $600,000 aggregate gross purchase consideration will be used as
general corporate working capital by EXCO.

         RICHARD D. COLLINS

         The Board of Directors authorized a payment of $23,736 to Richard D.
Collins, a former director of EXCO, for expenses related to attempting to locate
acquisition candidates for EXCO and consulting services rendered during 1997 to
EXCO.

         MAVERICK COUNTY, TEXAS ACQUISITION

   
         Effective January 1, 1998, EXCO acquired interests in 9 gross (7.0 net)
producing natural gas wells, 2 gross (1.87 net) nonproducing wells, 360 gross
(280 net) developed acres and 3,384 gross (2,843 net) undeveloped acres in
Maverick County, Texas (the "Acquisition"). The Acquisition included a majority
of the working interest and operator status for all but one of such wells. All
of the wells produce from the Glen Rose formation at depths between 5,000 and
5,900 feet. EXCO has identified at least two potential development well
locations, one of which was drilled and completed as a producing gas well in
April 1998. The estimated cost to EXCO for its 48.75% before payout (43.875%
after payout) interest in such well is $219,000. Reserve estimates as of
December 31, 1997 indicate that the SEC PV-10, attributable to EXCO's interest
in the current wells and two development wells is approximately $1.5 million.
All of the estimated reserves are classified as proved reserves, with 66%
attributable to proved developed producing reserves and 34% attributable to
proved undeveloped reserves. Richard E. Miller, General Counsel, General Land
Manager and Secretary of EXCO was one of the selling parties in the Acquisition
and received the sum of $29,440 for his interest as a seller. In the sale to
EXCO, Richard E. Miller retained an overriding royalty interest of less than 1%
in two of the producing wells purchased and a 17.5% working interest in the
development well which was drilled in April 1998. The sellers in the
Acquisition, including Richard E. Miller, retained an interest in future
drilling on certain of the acquired acreage, including the second of the two
development wells referred to above. The retained interest of the sellers was
equal to one-third of the interest they owned at the time of the sale. The
reserve estimates set forth above fully reflect and do not include the
interests retained by the sellers, including Richard E. Miller. In connection
with the Acquisition, Richard E. Miller also received a 3% finder's fee in the
amount of $22,806 for his role in bringing the Acquisition to EXCO's attention.
    
   

         J. MICHAEL MUCKLEROY

         During the fiscal year ended December 31, 1997, Mr. Muckleroy, who
became a director on March 31, 1998, owned the following working interests in
the following wells operated by EXCO: the Wilbanks #1 (4.18%); the McGarraugh
1-139 (2%); the Perkins #4 (6%); the Mitchell #1 (11.7%); the Mitchell #2 (18%);
and the Coats #5 (11%). Mr. Muckleroy received approximately $2,700 per month as
a result of his working interests in wells operated by EXCO. On March 5, 1998
the Board of Directors issued 12,500 shares of Common Stock, par value $.01 per
share, to Mr. Muckleroy in exchange for his working interest in the
aforementioned wells.
    

         GLENN L. SEITZ

         Mr. Seitz, a director of EXCO until December 19, 1997, owns working
interests in the following wells operated by EXCO: the Perkins #4 (.5%); the
Mitchell #1 (.5%); the Mitchell #2 (.5%); and the Coats #5 (.5%). Mr. Seitz
receives approximately $96 per month as a result of his working interests in
wells operated by EXCO.

INDEMNIFICATION ARRANGEMENTS

         EXCO has authority under Articles 2.02(A)(16) and 2.02-1 of the Texas
Business Corporation Act to indemnify its officers and directors to the extent
provided for in such statute.

         Article VI of EXCO's Restated Bylaws provides that EXCO shall indemnify
each of its directors and officers, its former directors and officers and agents
of EXCO against expenses actually and reasonably incurred by him or her in
connection with the defense of any action, suit or proceeding, civil or
criminal, in which such person is made a party by reason of being or having been
such director or officer, except in situations where he or she shall be adjudged
in such action, suit or proceeding to be liable for negligence or misconduct in
the performance of his or her duty to EXCO. In the event of a criminal
conviction (whether based on a plea of guilty or nolo contendere


                                       53

<PAGE>   56

or its equivalent, or after trial), such conviction shall not be deemed an
adjudication of liability for negligence or misconduct in the performance of
duty to EXCO if such director or officer acted in good faith in what he or she
considered to be the best interest of EXCO and without reasonable cause to
believe that his or her actions were illegal. In absence of an adjudication
which expressly absolves the director or officer of liability to EXCO or its
shareholders for negligence or misconduct, or in the event of a settlement, the
right to indemnification of a director or officer shall be conditioned upon
prior resolution adopted by two-thirds of the disinterested members of the Board
or by independent counsel.

         EXCO intends to maintain insurance against liabilities incurred by its 
officers and directors in defense of actions to which they are made parties by 
reason of their positions as officers and directors.

   
         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 is permitted for directors, officers or persons controlling EXCO
pursuant to the foregoing provisions, EXCO has been informed that in the opinion
of the Commission such indemnification is against public policy as expressed in
the Securities Act of 1933 and is therefore unenforceable.

                          DESCRIPTION OF CAPITAL STOCK
   
         EXCO's authorized capital stock consists of (i) 25,000,000 shares of
Common Stock and (ii) 10,000,000 shares of Preferred Stock. Upon consummation of
the Rights Offering and assuming all Rights are exercised, 6,537,696 shares of
Common Stock and no shares of Preferred Stock will be outstanding (before
adjustments for fractional shares). The following summary of EXCO's capital
stock does not purport to be complete and is subject to, and qualified in its
entirety by, the Articles of Incorporation. On March 31, 1998, EXCO consummated
a Reverse Stock Split. See "Recent Developments."
    

COMMON STOCK

   
         EXCO is authorized to issue 25,000,000 shares of Common Stock, par
value $.02 per share. At May 27, 1998, the record date for the Rights Offering,
there were  594,336 shares of Common Stock issued and outstanding held by
approximately 1,600 shareholders of record. All shares of Common Stock have
equal voting rights on the basis of one vote per share on matters to be voted on
by the shareholders. Cumulative voting for the election of directors is not
permitted. The vote or concurrence of two-thirds of the outstanding voting
shares of Common Stock is required for any amendments to the Articles of
Incorporation, or for the approval of any merger or consolidation, any
distributions in partial liquidation of EXCO, any sale, lease, exchange or other
disposition not in the ordinary course of business of all, or substantially all,
of the property or assets of EXCO or the dissolution of EXCO.
    

         Shareholders of Common Stock are entitled to receive dividends if, when
and as declared by the Board out of funds legally available therefor. Shares of
Common Stock have no preemptive, conversion, sinking fund, redemption or similar
provisions. In the event of liquidation of EXCO, shareholders of Common Stock
are entitled to share on a pro rata basis in the distribution of EXCO's assets,
if any, after the payment of liabilities and the liquidation preference, if any,
on any preferred stock then outstanding. All outstanding shares of Common Stock
are, and the shares of Common Stock being issued and sold by EXCO in the
offering made hereby, will be, when issued and paid for, fully paid and
nonassessable.

   
         A total of 1,000,000 shares of Common Stock have been reserved for
issuance under EXCO's 1998 Stock Option Plan of which, as of May 29, 1998,
1,000,000 shares remain available for grants of stock options.
    

PREFERRED STOCK

         EXCO is authorized to issue 10,000,000 shares of Preferred Stock. The
Preferred Stock may be issued in series, and shares of each series shall have
such rights and preferences as shall be fixed by the Board in the resolution or
resolutions authorizing the issuance of that particular series. In designating
any series of Preferred Stock the Board has authority, without further action by
the holders of Common Stock, to fix the number of shares


                                       55 

<PAGE>   58

constituting that series and to fix the dividends rights, dividend rate,
conversion rights, rights and terms of redemption (including any sinking fund
provisions), and the liquidation preferences of that series of Preferred Stock.
The issuance of Preferred Stock could adversely affect the voting power of
holders of Common Stock and the likelihood that such holders will receive
dividend payments and payments upon liquidation and could have the effect of
delaying, deferring or preventing a change in control of EXCO. EXCO has no
present plans to issue any shares of Preferred Stock.

   
TEXAS LAW AND CERTAIN CORPORATE PROVISIONS

         EXCO is subject to the provisions of Article 13 of the Texas
Business Corporation Act. In general, this statute prohibits a publicly-held
Texas corporation from engaging, under certain circumstances, in a "business
combination" with an "affiliated shareholder" for a period of three years after
the date of the transaction in which the person becomes an affiliated
shareholder, unless either (i) prior to the date at which the shareholder became
an affiliated shareholder the Board of Directors approved either the business
combination or the transaction in which the person becomes an affiliated
shareholder, or (ii) the business combination is approved by the Board of
Directors and by two-thirds of the outstanding voting stock of the corporation
(excluding shares held by the affiliated shareholder) at a meeting of the
shareholders (and not by written consent) held not earlier than six months after
the date on which the person became an "affiliated shareholder" of the business
combination. An "affiliated shareholder" is a person who, together with or
through affiliates and associates, beneficially owns or within the preceding
three-year period was the beneficial owner of 20% or more of the corporation's
outstanding voting stock. Article 13 defines a "business combination" to include
any merger, share exchange, conversion and asset based transactions and other
transactions resulting in a financial benefit to the affiliated shareholder or
an associate or affiliate of the affiliated shareholder.
    

LIMITATIONS ON LIABILITY

         As authorized by Article 1301-7.06 of the Texas Miscellaneous
Corporation Laws Act (the "TMCLA"), the Articles of Incorporation provide that
to the fullest extent, now or hereafter permitted by Texas law, EXCO's directors
will have no personal liability to EXCO or its shareholders for monetary damages
for breach or alleged breach of the directors' duty of care. This provision in
the Articles of Incorporation will not eliminate directors' liability resulting
from suits by third parties, and does not affect EXCO or its shareholders'
ability to obtain equitable remedies such as an injunction or a rescission of an
agreement or transaction deemed improper. Furthermore, each director will
continue to be subject to liability for (i) a breach of a director's duty of
loyalty to EXCO or its shareholders, (ii) an act or omission not in good faith
or that involves intentional misconduct or a knowing violation of the law, (iii)
a transaction from which a director received an improper benefit, whether or not
the benefit resulted from an action taken within the scope of the director's
office, (iv) an act or omission for which the liability of a director is
expressly provided for by statute, or (v) an act related to an unlawful share
repurchase or payment of a dividend.

                              PLAN OF DISTRIBUTION


   
     The Rights covered hereby may be offered and sold from time to time by 
the Selling Rightsholders. The shares of Common Stock purchased by the Standby
Purchaser and OCM may be offered and sold from time to time by the Standby
Purchaser and OCM. The Selling Rightsholders, the Standby Purchaser and OCM
will act independently of EXCO in making decisions with respect to the timing,
manner and size of each sale. Such sales may be made on the OTC Bulletin Board
(or other market on which the Rights and the Common Stock are listed or
otherwise qualified for trading), at market prices prevailing at the time of
the sale, at prices related to the then prevailing market price or in
negotiated transactions, including pursuant to an underwritten offering or
pursuant to one or more of the following methods: (i) purchases by a
broker-dealer as principal and resale by such broker or dealer for its account
pursuant to this Prospectus; (ii) ordinary brokerage transactions and
transactions in which a broker solicits purchasers; and (iii) block trades in
which a broker-dealer so engaged will attempt to sell the Rights or the Common
Stock as agent but may take a position and resell a portion of the block as
principal to facilitate the transaction. In effecting sales, broker-dealers
engaged by the Selling Rightsholders, the Standby Purchaser and OCM may arrange
for other broker-dealers to participate. Broker-dealers may receive commissions
or discounts from the Selling Rightsholders, the Standby Purchaser or OCM in
amounts to be negotiated immediately prior to the sale.
    

   
     In connection with the sale of Rights and shares of Common Stock covered
hereby, underwriters or agents may receive compensation from the Selling
Rightsholders, the Standby Purchaser or OCM or from purchasers of the Rights
and Common Stock covered hereby for whom they may act as agents, in the form of
discounts, concessions or commissions. Underwriters may sell Rights and shares
of Common Stock to or through dealers and such dealers may receive compensation
in the form of discounts, concessions or commissions from the underwriters
and/or commissions from the purchasers for whom they act as agents.
Underwriters, dealers and agents that participate in the distribution of Rights
and shares of Common Stock covered hereby may be deemed to be underwriters, and
any discounts or commissions received by them from the Selling Rightsholders
and any profit on the resale of Rights and shares of Common Stock by them may
be deemed to be underwriting discounts and commissions under the Securities
Act. Neither EXCO nor and any Selling Rightsholder can presently estimate the
amount of such compensation. 
    

   
         OCM, an investment fund managed by Oaktree Capital Management, LLC, has
indicated its desire to acquire and exercise Rights to purchase 1,000,000
shares of Common Stock. It is anticipated that such Rights would be acquired at
no cost from various affiliates of EXCO including Messrs. Miller, Eubank and
Ellis. OCM has indicated that it would not exercise its Rights unless at least
2,000,000 Rights have been exercised by other holders of Rights (including the
250,000 Rights Mr. Miller has stated he will exercise in satisfaction of the
condition of the Standby Purchaser to its purchase). OCM has also indicated a
desire that EXCO increase the size of its Board of Directors by one person and
that the vacancy created thereby be filled by a person to be nominated by OCM.
EXCO is willing to accommodate the request should OCM ultimately acquire
1,000,000 shares pursuant to the Rights Offering.
    

   
         Selling Rightsholders may also convey, without charge or other form of
compensation, their Rights to other nonaffiliated third parties.
    

   
     EXCO knows of no other existing arrangements between any Selling
Rightsholder and any other shareholder, broker, dealer, underwriter or agent
relating to the sale or distribution of the Common Stock.
    

   
    

   
     To the extent required, EXCO will file, during any period in which offers
or sales are being made, a supplement to this Prospectus which sets forth, with
respect to a particular offering, the specific number of Rights and shares of
Common Stock to be sold, the name of the holder, the sales price, the name of
any participating broker, dealer, underwriter or agent, any applicable
commission or discount and any other material information with respect to the
plan of distribution not previously disclosed.
    

   
         In order to comply with certain states' securities laws, if 
applicable, the Rights and shares of Common Stock will be sold in such 
jurisdictions only through registered or licensed brokers or dealers. In 
addition, in certain states the Rights and shares of Common Stock may not be 
sold unless the shares have been registered or qualified for sale in such state 
or an exemption from registration or qualification is available and is 
satisfied.

                    MATERIAL FEDERAL INCOME TAX CONSIDERATIONS
    

GENERAL
   

         The following summarizes Haynes and Boone, LLP's opinion regarding the
material federal income tax consequences of the Rights Offering. This discussion
is based on the provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), the Treasury Regulations promulgated thereunder, and administrative and
judicial interpretations thereof, all as in effect as of the date hereof and all
of which are subject to change (possibly on a retroactive basis). This
discussion does not purport to deal with all aspects of federal income taxation
that may be relevant to a particular holder of Rights in light of such holder's
personal investment circumstances nor does this discussion address special tax
implications which may be applicable to certain types of holders of Rights
subject to special treatment under the Code (including, without limitation,
financial institutions, broker-dealers, regulated investment companies, life
insurance companies, tax-exempt organizations, foreign corporations and
non-resident aliens). Moreover, the discussion is limited to those holders who
will hold the Rights and any Common Stock acquired upon the exercise of Rights,
as capital assets (generally, property held for investment) within the meaning
of Section 1221 of the Code. No consideration of any aspects of state, local or
foreign taxation is included herein. EXCO has not sought, nor does it intend to
seek, any rulings from the IRS relating to the tax issues addressed herein, and
such issues may be subject to substantial uncertainty resulting from the lack of
definitive judicial or administrative authority and interpretations applicable
thereto.
    

   
         EACH EXISTING HOLDER OF COMMON STOCK AND EACH PROSPECTIVE HOLDER OF
RIGHTS IS URGED TO CONSULT SUCH PERSON'S OWN TAX ADVISOR AS TO THE SPECIFIC TAX
CONSEQUENCES OF THE RIGHTS OFFERING WITH RESPECT TO SUCH PERSON'S OWN PARTICULAR
TAX SITUATION, INCLUDING THE APPLICATION AND EFFECT OF THE CODE, AS WELL AS
STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS.

TAX CONSEQUENCES TO HOLDERS OF RIGHTS

         ISSUANCE OF RIGHTS TO EXISTING SHAREHOLDER

   
         Haynes and Boone, L.L.P., counsel to EXCO, has rendered an opinion that
the distribution of Rights to holders of common stock ("Existing Shareholders")
should be characterized as a non-taxable distribution under Section 305(a) of
the Code ("Section 305(a) distribution"), although this matter is not free from
doubt. If the Rights distribution is treated as a Section 301 Distribution, and
provided that EXCO does not have positive net earnings during fiscal 1998, the
value of the Rights distributed would be treated as a nontaxable reduction in
the Existing Shareholder's basis in his Common Stock, and the balance (if any)
in excess of such adjusted basis would be taxed as capital gain.
    

         BASIS OF RIGHTS

   
         If, the Rights distribution is properly characterized as a Section
305(a) Distribution, then, except as provided in the following sentence, the tax
basis of Rights received by an Existing Shareholder in the Rights distribution
would be zero. If, however, (i) the Rights distribution constitutes a Section
305(a) Distribution and (ii) either the Rights have a value (on the date of
distribution of the Rights) equal to or greater than 15% of the value of the
shares of Common Stock with respect to which the Rights are distributed or the
Existing Shareholder elects to apply the rule described in this sentence, then
upon exercise or transfer (but not upon lapse) of the Rights, the Existing
Shareholder would reallocate his tax basis in his Common Stock between the
Rights and the Common Stock based on the relative fair market values of each. If
the Rights distribution is treated as a Section 301 Distribution, an Existing
Shareholder would have a tax basis in the Rights equal to (and, assuming that
EXCO does not have positive net earnings during fiscal 1998, the Existing
Shareholder's basis in his Common Stock would be reduced by) the fair market 
value of the Rights on the date of the Rights distribution. Persons who acquire 
Rights by purchase will have a tax basis in the Rights equal to the purchase 
price paid therefor.
    

         HOLDING PERIOD OF RIGHTS

   
         If, the Rights distribution is treated as a Section 305(a)
Distribution, an Existing Shareholder will have a holding period in the Rights
that includes the holding period of the shares of Common Stock to which the
Rights distribution relates. If the Rights distribution is treated as a Section
301 Distribution, the Existing Shareholder would have a holding period in the
Rights that begins on the day following the date of distribution of the Rights.
A holder who acquires Rights by purchase will have a holding period in the
Rights that begins on the date of purchase.
    

         EXERCISE OR SALE OF RIGHTS

   
         A holder of Rights will not be taxed upon exercise of the Rights. The
holder's tax basis in the shares of Common Stock received upon exercise will
equal (i) his basis in the Rights, plus (ii) the Subscription Price paid for the
Common Stock. The holder's holding period in the Common Stock will begin on the
day following the date of exercise of the Rights. Upon a sale of the Rights, a
holder of Rights will realize capital gain or loss equal to the difference
between the amount received (if any) for the Rights and his tax basis in the
Rights (determined as described in "-- Basis of Rights," above).
    

         LAPSE OF RIGHTS

         A holder of Rights who allows Rights to lapse would have a capital loss
equal to his basis (determined as described in "-- Basis of Rights," above), if
any, in the Rights that lapsed. If the Rights distribution is treated as a
Section 305(a) Distribution, an Existing Shareholder who allows a Right to lapse
will have no basis in the Right and, thus, would realize no capital loss.

         SALE OR CASH REDEMPTION OF COMMON STOCK

         Upon a sale or cash redemption of shares of Common Stock, a holder who
acquired Rights by purchase and, if (as expected) EXCO has no net earnings
during fiscal 1998, an Existing Shareholder, will generally recognize


                                       60

<PAGE>   63

capital gain or loss in an amount equal to the difference between the amount
received in the sale or redemption and the holder's tax basis (determined as
described in "-- Exercise or Sale of Rights," above) in the shares redeemed.

                 GLOSSARY OF SELECTED OIL AND NATURAL GAS TERMS

         The following are abbreviations and definitions of certain terms
commonly used in the oil and natural gas industry and this Prospectus.

         "BBL." One stock tank barrel, or 42 U.S. gallons liquid volume, used
herein in reference to crude oil or other liquid hydrocarbons.

         "BEHIND-PIPE." Hydrocarbons in a potentially producing horizon
penetrated by a well bore the production of which has been postponed pending the
production of hydrocarbons from another formation penetrated by the well bore.
These hydrocarbons are classified as proved but nonproducing reserves.

         "BOE." Barrel of oil equivalent (converting six Mcf of natural gas to
one Bbl of oil).

         "COMPLETED WELL." The completion of a well or a completed well refers
to the installation of permanent equipment for the production of oil or natural
gas, or in the case of a dry hole, the reporting of abandonment to the
appropriate agency.

         "DEVELOPED ACREAGE." Acreage spaced or assignable to productive wells.

         "DEVELOPMENT WELL." A well drilled within the proven boundaries of an
oil or natural gas reservoir with the intention of completing the stratigraphic
horizon known to be productive.

         "DRY HOLE." An exploratory or development well found to be incapable of
producing either oil or natural gas in sufficient economic quantities to
justify completion of a well.

         "EXPLORATORY WELL." A well drilled within no proven boundaries of an
oil or natural gas reservoir.

         "GROSS ACRE." An acre in which a working interest is owned.

         "GROSS WELL(S)." A gross well is a well in which a working interest is
owned. The number of gross wells is the total number of wells in which working
interests are owned.

         "INFILL DRILLING." Drilling of a well between known producing wells to
better exploit the reservoir.

         "MCF." One thousand cubic feet of natural gas.

         "MCFE." One thousand cubic feet of natural gas equivalent (converting
one Bbl of oil to six Mcf of natural gas).

         "NET ACRE(S)." A net acre is deemed to exist when the sum of fractional
ownership working interests in gross acres equals one. The total of net acres is
the sum of the fractional working interests owned in gross acres expressed as
whole numbers and percentages thereof.

         "NET WELL(S)." A net well is deemed to exist when the sum of the
fractional ownership working interests in gross wells equals one. The number of
net wells is the sum of the fractional working interests owned in gross wells
expressed as whole numbers and percentages thereof.

         "OVERRIDING ROYALTY INTEREST." An interest in an oil and/or natural gas
property entitling the owner to a share of oil and natural gas production free
of costs of production.

         "PRESENT VALUE OF ESTIMATED FUTURE NET REVENUES." The present value of
estimated future net revenues is an estimate of future net revenues from a
property at its acquisition date, at December 31, 1997, or as otherwise
indicated, after deducting production and ad valorem taxes, future capital costs
and operating expenses, but before deducting federal income taxes. The future
net revenues have been discounted at an annual rate of 10% to determine


                                       64

<PAGE>   67
their "present value." The present value is shown to indicate the effect of time
on the value of the net revenue stream and should not be construed as being the
fair market value of the properties. Estimates have been made using constant oil
and natural gas prices and operating costs at the acquisition date, at December
31, 1997, or as otherwise indicated. EXCO believes that the present value of
estimated future net revenues before income taxes, while not in accordance with
generally accepted accounting principles, is an important financial measure used
by investors and independent oil and natural gas producers for evaluating the
relative significance of oil and natural gas properties and acquisitions.

         "PRODUCING WELL," "PRODUCTION WELL" or "PRODUCTIVE WELL." A well that
is producing oil or natural gas or that is capable of production.

   
         "PROVED DEVELOPED RESERVES." Proved developed reserves are oil and gas
reserves that can be expected to be recovered through existing wells with
existing equipment and operating methods. Additional oil and gas expected to be
obtained through the application of fluid injection or other improved recovery
techniques for supplementing the natural forces and mechanisms of primary
recovery should be included as "proved developed reserves" only after testing by
a pilot project or after the operation of an installed program has confirmed
through production response that increased recovery will be achieved.
    

         "PROVED RESERVES." The estimated quantities of crude oil, natural gas
and NGLs 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 UNDEVELOPED RESERVES." Proved undeveloped reserves are oil and 
gas reserves that are expected to be recovered from new wells on undrilled
acreage, or from existing wells where a relatively major expenditure is required
for recompletion. Reserves on undrilled acreage shall be limited to those
drilling units offsetting productive units that are reasonably certain of
production when drilled. Proved reserves for other undrilled units can be
claimed only where it can be demonstrated with certainty that there is
continuity of production from the existing productive formation. Under no
circumstances should estimates for proved undeveloped reserves be attributable
to any acreage for which an application of fluid injection or other improved
recovery techniques is contemplated, unless such techniques have been proved
effective by actual tests in the area and in the same reservoir.
    

         "SEC PV-10." The discounted future net cash flows for proved oil and
natural gas reserves computed on the same basis as the Standardized Measure, but
without deducting income taxes, which is not in accordance with generally
accepted accounting principles. SEC PV-10 is an important financial measure for
evaluating the relative significance of oil and natural gas properties and
acquisitions, but should not be construed as an alternative to the Standardized
Measure (as determined in accordance with generally accepted accounting
principles).

         "UNDEVELOPED ACREAGE." As defined by the Commission, undeveloped
acreage is considered to be lease acreage on which wells have not been drilled
or completed to a point that would permit the production of commercial
quantities of oil and natural gas regardless of whether such acreage contains
proved reserves.

         "WORKING INTEREST." The operating interest that gives the owner the
right to drill, produce and conduct operating activities on the property and to
a share of production, subject to all royalties, overriding royalties and other
burdens and to all costs of exploitation, development and operations and all
risks in connection herewith.

                         REPORT OF INDEPENDENT AUDITORS


The Board of Directors and Stockholders
EXCO Resources, Inc.

   
We have audited the accompanying balance sheet of EXCO Resources, Inc., as of
December 31, 1997, and the related statements of operations, cash flows, and
changes in stockholders' equity for the year then ended. These financial
statements are the responsibility of EXCO'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 financial statements referred to above present fairly, in
all material respects, the financial position of EXCO Resources, Inc., at
December 31, 1997, and the results of its operations and its cash flows for the
year then ended in conformity with generally accepted accounting principles.

As explained in Note 2 to the financial statements, EXCO Resources, Inc. has

                         REPORT OF INDEPENDENT AUDITORS


The Board of Directors and Stockholders
EXCO Resources, Inc.

We have audited the accompanying balance sheet of EXCO Resources, Inc. as of
December 31, 1996, and the related statements of operations, cash flows and
changes in stockholders' equity for the nine months ended December 31, 1995 and
year ended December 31, 1996. These financial statements are the responsibility
of the Company's management. Our responsibility is to express an opinion on
these financial statements based on our audits.

We conducted our audits 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 our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of EXCO Resources, Inc. as of
December 31, 1996, and the results of its operations and its cash flows for the
nine months ended December 31, 1995 and year ended December 31, 1996, in
conformity with generally accepted accounting principles.

As explained in Note 2 to the financial statements, EXCO Resources, Inc. has
given retroactive effect to the change in accounting for all oil and gas
properties from the successful efforts method to the full cost method.

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

EXCO, a Texas corporation, was formed in 1955. EXCO's operations consist
primarily of acquiring interests in producing oil and natural gas properties
located in the continental United States. EXCO also acts as the operator on
certain of these properties and receives overhead reimbursement fees as a
result.

On December 19, 1997, a new stockholder (the "Buyer") took control of EXCO and
its management under an option agreement, and a separate stock purchase
agreement between the Buyer and certain shareholders of EXCO (the "Sellers"),
whereby the Buyer purchased certain outstanding common stock from the Sellers.

QUASI-REORGANIZATION

   
Effective December 31, 1997, EXCO effected a quasi-reorganization through the
application of $8,799,000 of its additional paid-in capital account to eliminate
its accumulated deficit. EXCO's Board of Directors decided to effect a
quasi-reorganization given the change in management, the infusion of new equity
capital and an increase in activities. EXCO's accumulated deficit was primarily
related to past operations and properties that have been disposed of. The
historical carrying values of the assets and liabilities of EXCO were not
required to be adjusted in connection with the quasi-reorganization.
    

YEAR-END CHANGE

On February 13, 1996, EXCO changed its fiscal year-end from March 31 to December
31 effective December 31, 1995.

MANAGEMENT ESTIMATES

In preparing financial statements in conformity with generally accepted
accounting principles, EXCO is required to make estimates and assumptions that
affect the reported amounts of assets, liabilities, revenues and expenses during
the reporting period. Actual results may differ from management's estimates.

CASH EQUIVALENTS

EXCO considers all highly liquid investments with maturities of 3 months or less
when purchased to be cash equivalents.

CONCENTRATION OF CREDIT RISK AND ACCOUNTS RECEIVABLE

Financial instruments that potentially subject EXCO to concentration of credit
risk consist principally of cash and trade receivables. EXCO places its cash
with high credit quality financial institutions. EXCO sells oil and natural gas
to various customers. In addition, EXCO participates with other parties in the
drilling, completion, and operation of oil and natural gas wells. Substantially
all of EXCO's accounts receivable are due from either purchasers of oil, natural
gas, or natural gas liquids or participants in oil and natural gas wells for
which EXCO serves as the operator. Generally, operators of oil and natural gas
properties have the right to offset future revenues against unpaid charges
related to operated wells. Oil and natural gas sales are generally unsecured.
Credit losses are provided for in the financial statements and have been within
management's expectations. The allowance for doubtful accounts receivable
aggregated $20,000 and $18,000 at December 31, 1996 and 1997, respectively.

                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 1997

            (Information subsequent to December 31, 1997, and for the
                three months ended March 31, 1998, is unaudited)


OIL AND NATURAL GAS PROPERTIES

Oil and natural gas properties are recorded at cost using the full cost method
of accounting, as prescribed by the Securities and Exchange Commission (the
"SEC"). Under the full cost method, all costs associated with the acquisition,
exploration or development of oil and natural gas properties are capitalized as
part of the full cost pool.

Depreciation, depletion, and amortization of evaluated oil and natural gas
properties are provided using the unit-of-production method based on total
proved reserves, as determined by independent petroleum reservoir engineers.

Sales, dispositions, and other oil and natural gas property retirements are
accounted for as adjustments to the full cost pool, with no recognition of gain
or loss unless such disposition would significantly alter the amortization rate.

   
OFFICE AND FIELD EQUIPMENT

Office and field equipment are capitalized at cost and depreciated on a straight
line basis over their estimated useful lives.

REVENUE RECOGNITION

EXCO uses the sales method of accounting for oil and gas revenues. Under the
sales method, revenues are recognized based on actual volumes of oil and gas
sold to purchasers.
    

OVERHEAD REIMBURSEMENT FEES

Fees from overhead charges billed to working interest owners, including EXCO, of
$115,000, $138,000, and $136,000 for the nine months ended December 31, 1995,
and for the years ended December 31, 1996 and 1997, respectively, have been
classified as a reduction of general and administrative expenses in the
accompanying statements of operations. For the nine months ended December 31,
1995 and the year ended December 31, 1996, these amounts were previously shown
as revenues.

INCOME TAXES

Deferred income taxes are accounted for using the liability method in accounting
for income taxes.

EARNINGS PER SHARE

In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share. Statement No. 128 replaced the calculation of primary and
fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All earnings per share amounts for all periods have been
presented, and where appropriate, restated, to conform to the Statement 128
requirements. The effect of the adoption of Statement No. 128 did not have a
material impact.

                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 1997

            (Information subsequent to December 31, 1997, and for the
                three months ended March 31, 1998, is unaudited)


   
REVERSE STOCK SPLITS

At EXCO's 1998 Annual Meeting of Shareholders, the shareholders of EXCO approved
an amendment to EXCO's Restated Articles of Incorporation authorizing a
one-for-two reverse stock split of EXCO's common stock, which became effective
March 31, 1998. At EXCO's 1996 Annual Meeting of Shareholders, the shareholders
of EXCO approved an amendment to EXCO's Articles of Incorporation authorizing a
one-for-five reverse stock split of EXCO's common stock, which became effective
July 19, 1996. All share and per share numbers contained herein have been
retroactively adjusted to record the effects of the reverse stock splits. (See
Note 10).
    

PREFERRED STOCK

At the 1996 Annual Meeting, the shareholders also authorized the issuance of up
to 10,000,000 shares of preferred stock, $.01 par value per share (the
"Preferred Stock"), that the Board of Directors may issue from time to time in
one or more series. With respect to each series of Preferred Stock, the
amendment authorizes the Board to fix and determine by resolution the number of
shares of each series, the designation thereof and all rights and preferences
including voting, dividend, conversion, redemption and liquidation rights. The
Board of Directors deemed it in the best interest of EXCO to provide for
corporate planning and to have shares available for future equity financings
through issuance to the general public, future acquisitions, stock dividends or
splits or for other corporate purposes for which the issuance of preferred
shares may be advisable.

   
INTERIM FINANCIAL STATEMENT PRESENTATION

In management's opinion, the accompanying interim financial statements contain
all adjustments (consisting solely of normal recurring accruals) necessary to
present fairly the financial position of EXCO as of March 31, 1998, the results
of operations for the three month periods ended March 31, 1997 and 1998, and the
cash flows for the three month periods ended March 31, 1997 and 1998.

The results of operations for the three months ended March 31, 1998, are not
necessarily indicative of the results expected for the full year.
    

2.       CHANGE IN METHOD OF ACCOUNTING FOR OIL AND NATURAL GAS OPERATIONS

In the fourth quarter of 1997, EXCO changed from the successful efforts method
to the full cost method of accounting for its oil and natural gas operations.
All prior year's financial statements presented herein have been restated to
reflect the change.

   
During the past ten years, EXCO has incurred minimal exploration and acquisition
costs, has liquidated substantially all its properties and in 1987 and 1988
completed certain "out of court" debt restructurings. Recently there was a
change in control of ownership of EXCO and new management was appointed. New
management views EXCO as a new company and believes the past operations are
insignificant and not relevant to EXCO's future plans.
    

New management believes that the change in accounting for oil and natural gas
properties is to a preferable method because the full cost method will more
appropriately reflect EXCO's future operations which will result from the
significant management changes at EXCO. Further, new management does not believe
that the use of the successful efforts method of accounting is appropriate for a
small to medium size acquisition, development and exploitation company.

NATIONSBANK CREDIT AGREEMENT

On February 11, 1998, EXCO entered into a credit agreement with NationsBank of
Texas, N.A., ("NationsBank") (the "Credit Agreement"). The Credit Agreement has
a notional amount to $50 million, subject to borrowing base limitations, based
on the value of EXCO's oil and gas properties, as determined by the lenders from
time to time.


                                      F-11

<PAGE>   79
                              EXCO RESOURCES, INC.

                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 1997

            (Information subsequent to December 31, 1997, and for the
                three months ended March 31, 1998, is unaudited)


Under the Credit Agreement, EXCO is required to pay a fee equal to .25% on any
accepted increase in the borrowing base in excess of the previously determined
borrowing base and a commitment fee of .30% to .425% based on the ratio of
outstanding credit to the borrowing base. The maturity date of the Credit
Agreement is February 11, 2000.

The Credit Agreement provides that if EXCO's outstanding credit is less than $5
million, then EXCO's interest rate would be LIBOR plus 1.5%. If EXCO's
outstanding credit is greater than $5 million, then the Credit Agreement
provides that EXCO's interest rate would range from NationsBank's prime rate to
LIBOR plus between 1% and 1.75% based on the ratio of outstanding credit to the
borrowing base.

There are no scheduled principal payments due on the Credit Agreement until
maturity. However, the borrowing base will be redetermined on or around April 1
and October 1 of each year. A borrowing base deficiency is created in the event
that the outstanding loan balances exceed the borrowing base, as determined by
the lenders in their sole discretion. Upon such event the borrowing base
deficiency must be repaid by (i) mandatory reductions of the deficiency over a
period of not more than 6 months; (ii) making a lump sum payment equal to the
deficiency; or (iii) providing additional collateral acceptable to lenders in
their sole discretion sufficient to increase the borrowing base and eliminate
the deficiency.

   
Borrowings under the Credit Agreement are secured by first and prior liens
covering 90% of the recognized value of all proved mineral interests owned by
EXCO. The Credit Agreement contains various restrictive covenants, including
limitations on the granting of liens, restrictions on the issuance of additional
debt, requirements to maintain a net worth of at least $.5 million and to
maintain a current ratio of not less than 1.0 to 1.0, and currently prohibits
the payment of dividends on EXCO's capital stock. On December 31, 1997, if the
Credit Facility had been outstanding at that time, EXCO would have been in
compliance with both the Current Ratio and the Consolidated Tangible Net Worth
covenants. On March 31, 1998, EXCO was in compliance with the Consolidated
Tangible Net Worth covenant, but was not in compliance with the Current Ratio
covenant. On May 15, 1998, NationsBank waived EXCO's noncompliance with the
Current Ratio at March 31, 1998. On May 15, 1998, EXCO was in compliance with
both the Current Ratio and the Consolidated Tangible Net Worth covenants. EXCO
believes, but cannot assure, that it will be able to comply with all restrictive
covenants in the future.
    

4.       INCOME TAXES

At December 31, 1997, EXCO has net operating loss carryforwards ("NOLs") for
income tax purposes that expire beginning in 1998. Utilization of the NOLs is
significantly restricted because of a change in ownership, as defined by the Tax
Reform Act of 1986, of EXCO, which occurred December 19, 1997, as described in
Note 1. EXCO estimates that approximately $1.9 million of the NOLs will become
available in the future at the rate of approximately $127,000 per year through
2012. EXCO also has available statutory depletion carryforwards of approximately
$927,000. For financial reporting purposes, a valuation allowance has been
recognized to offset the deferred tax assets related to carryforwards prior to
EXCO's quasi-reorganization. When realized, the tax benefit for those
carryforwards will be credited to additional paid-in capital.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
EXCO's deferred tax liabilities and assets are as follows (in thousands):

5.       COMMON STOCK OPTIONS

EXCO applies Accounting Principles Board Opinion 25 in accounting for its fixed
and performance-based stock compensation plans and disclosure requirements of
SFAS 123. Accordingly, no compensation costs have been recognized for either of
the plans.

During the nine month period ended December 31, 1995, EXCO issued 120,000
options to purchase EXCO Common Stock at $1.875 per share. These options were
exercised in 1996. In December 1997, as part of the change in control described
in Note 1, all outstanding options under EXCO's stock option plan and directors
option plan were canceled.

6.       RELATED PARTY TRANSACTIONS

In the past, certain directors of EXCO, and the companies with which they are
affiliated, participated in oil and natural gas joint ventures with EXCO upon
the same terms and conditions as unrelated parties. In addition, EXCO had
purchased certain oil and natural gas prospects as well as drilling services and
oil field supplies and services in the normal course of business from companies
in which certain directors have financial interest. No significant purchases
were made during the nine month period ended December 31, 1995, and the years
ended December 31, 1996 and 1997.

7.       COMMITMENTS AND CONTINGENCIES

EXCO leased office space under an operating lease that expired in November,
1996. Rent expense was approximately $32,000, $41,000 and $63,000 for the nine
months ended December 31, 1995, and the years ended December 31, 1996 and 1997,
respectively. As of December 31, 1997, EXCO moved its offices to a new location
under an operating lease that expires in December, 1999. The rent under the new
lease is $6,440 per month plus a CPI increase in year two.

EXCO had entered into an employment agreement with Mr. Charles Gleeson for the
position of President and Chief Executive Officer of EXCO. The agreement
provided for a minimum annual salary, adjusted for incentives, as determined by
the Board of Directors for the period June 1, 1996 through June 1, 1999. EXCO
had thought to terminate the employment agreement if EXCO was unsuccessful in
raising a minimum of $9,000,000 in a registered public offering. Mr. Gleeson's
employment agreement was terminated in December 1997, as a result of the change
in control described in Note 1.

8.       ENVIRONMENTAL REGULATION

   
Various Federal, state and local laws and regulations covering discharge of
materials into the environment, or otherwise relating to the protection of the
environment, may affect EXCO's operations and costs of oil and natural gas
exploitation, development and production operations. It is not anticipated that
EXCO will be required in the near future to expend amounts material in relation
to the financial statements taken as a whole by reason of environmental laws and
regulations. Because such laws and regulations are constantly being changed,
EXCO is unable to predict the conditions and other factors, over which EXCO does
not exercise control, that may give rise to environment liabilities.
    

9.       ABANDONED ACQUISITION

In September 1996, EXCO entered into a stock purchase agreement to acquire
Taurus Energy Corp. ("Taurus"), a processor and marketer of natural gas. In
addition, EXCO initiated a public stock offering to raise the $35,000,000
necessary to complete the acquisition.

In connection with these activities, EXCO incurred and capitalized approximately
$303,000 of legal, accounting and other costs. In the fourth quarter of 1996,
EXCO recognized the abandonment of the proposed Taurus acquisition and canceled
its planned public offering. As a result, EXCO expensed the costs associated
with these actions.

10.      SUBSEQUENT EVENTS

In addition to the financing agreement described in Note 3, on February 11,
1998, EXCO acquired from Osborne Oil Company, Gypsy Production Company, and
other working interest owners, certain oil and natural gas properties in
Maverick County, Texas (the "Maverick County Properties"). The Maverick County
Properties include 9 gross (7.0 net) producing wells and 2 gross (1.87 net)
non-producing wells which may require recompletions, workovers or abandonment.
The Maverick County Properties include 360 gross (280 net) developed acres and
3,384 gross (2,843 net) undeveloped acres. The purchase price consisted of cash
of approximately $760,200. Operating revenues for the acquired properties for
1997 were $279,000.

Incorporation authorizing a one-for-two reverse stock split of EXCO's common
stock, which became effective March 31, 1998. All share and per share numbers
contained herein have been retroactively adjusted to record the effects of the

All of EXCO's oil and natural gas revenues are produced from a limited number 
of wells or properties which are located in the United States.
    

   
    

EXCO's oil and natural gas production is sold to various purchasers. During the
nine months ended December 31, 1995, sales of oil and natural gas to 3
purchasers accounted for 20%, 13% and 10% of consolidated gross revenues,
respectively. During the year ended December 31, 1996, sales of oil and natural
gas to 2 purchasers accounted for 26% and 15% of consolidated gross revenues,
respectively. During the year ended December 31, 1997, sales of oil and natural
gas to 3 purchasers accounted for 22%, 19% and 14% of consolidated gross
revenues, respectively.

Management believes that the loss of these purchasers would not have a material
impact on EXCO's consolidated financial condition or results of operations.

In an effort to reduce the effects of the volatility of the price of crude oil
and natural gas on EXCO's operations, management has adopted a policy of hedging
oil and natural gas prices whenever such prices are in excess of the prices
anticipated in EXCO's operating budget and profit plan through the use of
commodity futures, options, and swap agreements. Hedging transactions require
the approval of the Board of Directors. There were no outstanding contracts at
December 31, 1997.

12. Supplemental Oil and Natural Gas Reserve and Standardized Measure 
    Information (Unaudited)

EXCO retains independent engineering firms to provide annual year-end estimates
of EXCO's future net recoverable oil, natural gas, and natural gas liquids
reserves. Estimated proved net recoverable reserves as shown below include only
those quantities that can be expected to be commercially recoverable at prices
and costs in effect at the balance sheet dates under existing regulatory
practices and with conventional equipment and operating methods. Proved
developed reserves represent only those reserves to be recovered through
existing wells. Proved undeveloped reserves include those reserves expected to
be recovered from new wells on undrilled acreage or from existing wells on which
a relatively major expenditure is required for recompletion.

* Boe - Barrels of oil equivalent calculated by converting 6 Mcf of natural gas
to 1 Bbl of oil. The following is a summary of a standardized measure of
discounted net cash flows related to EXCO's proved oil, natural gas, and natural
gas liquids reserves. The information presented is based on a valuation of
proved reserves using discounted cash flows based on year-end prices, costs, and
economic conditions and a 10% discount rate. The additions to proved reserves
from new discoveries and extensions could vary significantly from year to year;
additionally, the impact of changes to reflect current prices and costs of
reserves proved in prior years could also be significant. Accordingly, the
information presented below should not be viewed as an estimate of the fair
value of EXCO's oil and natural gas properties, nor should it be considered
indicative of any trends.

During recent years, there have been significant fluctuations in the prices paid
for crude oil in the world markets. This situation has had a destabilizing
effect on crude oil's posted prices in the United States, including the posted
prices paid by purchasers of EXCO's crude oil. The weighted average prices of
oil and natural gas at December 31, 1996 and 1997, used in the above table, were
$24.29 and $16.74 per Bbl, respectively, and $3.40 and $2.11 per Mcf,
respectively.

13. Pro Forma Combined Condensed Financial Statements (Unaudited)

On February 11, 1998, EXCO Resources, Inc. (the "Company") acquired from
Osborne Oil Company, Gypsy Production Company, and other working interest
owners, certain oil and gas properties in Maverick County, Texas (the "Maverick
County Properties"). The Maverick County Properties include 9 gross (7.0 net)
producing wells, 2 gross (1.87 net) non-producing wells which may require
recompletions, workovers or abandonment. The Maverick County Properties include
360 gross (280 net) developed acres and 3,384 gross (2,843 net) undeveloped
acres. The purchase price consisted of cash of approximately $760,200.

The acquisition was funded through borrowings made under the Company's credit
facility with NationsBank (the "Borrowings"), and cash from working capital.

The accompanying pro forma combined condensed financial statements are based on
the historical financial statements of the Company for the three months ended
March 31, 1998, included elsewhere herein. The pro forma combined
condensed financial statements are also based, in part, on the historical
statements of operating revenues and direct operating expenses of the Maverick
County Properties. Such statements of operating revenues and direct operating
expenses are included elsewhere herein.

The Pro Forma Combined Condensed Statement of Operations for the three months
ended March 31, 1998, has been prepared assuming the acquisition of the
Maverick County Properties and the Borrowings had been consummated on 
January 1, 1998.

The pro forma adjustments are based upon available information and assumptions
that management of the Company believes are reasonable. The pro forma combined
condensed financial statements do not purport to represent the financial
position or results of operations of the Company which would have occurred had
such transactions been consummated on the dates indicated or the Company's
financial position or results of operations for any future date or period.
These pro forma combined condensed financial statements and notes thereto
should be read in conjunction with the historical financial statements and
notes thereto described above.

On February 11, 1998, EXCO acquired from Osborne Oil Company, Gypsy Production
Company, and other working interest owners, certain oil and natural gas
properties in Maverick County, Texas (the "Maverick County Properties"). The
Maverick County Properties include 9 gross (7.0 net) producing wells, 2 gross
(1.87 net) non-producing wells which may require recompletions, workovers or
abandonment. The Maverick County Properties include 360 gross (280 net)
developed acres and 3,384 gross (2,843 net) undeveloped acres. The purchase
price consisted of cash of approximately $760,200.

The acquisition was funded through borrowings made under EXCO's credit facility
with NationsBank (the "Borrowings"), and cash from working capital.

   
As of May 1, 1998, EXCO entered into a merger agreement with Gladstone
Resources, Inc. ("Gladstone") whereby Gladstone will be merged into EXCO. On the
closing date, Gladstone stockholders are expected to receive approximately $1.4
million in cash for all of the outstanding capital stock of Gladstone. The
merger, which is expected to close on or before July 31, 1998, will be funded
from net proceeds of the rights offering (the "Offering").

On May 8, 1998, EXCO purchased all of the outstanding capital stock of
Jacobi-Johnson Energy, Inc. ("Jacobi-Johnson"). The aggregate purchase price was
approximately $1.4 million, consisting of approximately $703,000 in cash, and
85,436 shares of EXCO common stock. The cash portion of the consideration
was funded through borrowings made under EXCO's credit facility with
NationsBank.
    

   
On May 29, 1998, EXCO executed a non-binding letter of intent to acquire from
J.M. Hill, J.M. Hill, Trustee, Walter O. Hill and Steve J. Devos, certain oil
and natural gas properties in Dawson and Brazos Counties, Texas (the "Dawson
County Properties"). The Dawson County Properties include 11 gross (3.4 net)
producing wells and 4 gross (.85 net) saltwater disposal and  non-producing
wells which may require recompletions, workovers or abandonment. The Dawson
County Properties include 645 gross (251 net) developed acres and 889 gross (119
net) undeveloped acres. The purchase price is $1,364,000 cash to be paid for
using funds available under EXCO's Credit Facility.
    

The accompanying pro forma combined condensed financial statements are based on
the historical financial statements of EXCO for the year ended December 31,
1997, and the three months ended March 31, 1998, included elsewhere herein. The
pro forma combined condensed financial statements are also based, in part, on
the historical financial statements of Jacobi-Johnson and Gladstone, and on the
historical statements of operating revenues and direct operating expenses of the
Maverick County Properties and the Dawson County Properties. Such historical
financial statements and statements of operating revenues and direct operating
expenses are included elsewhere herein.

   
The Pro Forma Combined Condensed Balance Sheet as of  March 31, 1998, assumes
the acquisition of Jacobi-Johnson, Gladstone, the Dawson County Properties, the
Offering and the Borrowings had been consummated on that date. The Pro Forma
Combined Condensed Statement of Operations for the year ended December 31, 1997,
and the three months ended March 31, 1998, been prepared assuming the

Reserve Quantity Information

   
The following table presents EXCO's estimate of the pro forma combined proved
oil and natural gas reserves of EXCO after giving effect to the acquisition of
the Maverick County Properties, Jacobi-Johnson, Gladstone and the Dawson County
Properties as of December 31, 1997. All reserves are located in the United
States. EXCO emphasizes that reserve estimates are inherently imprecise and that
estimates of new discoveries are more imprecise than those of producing oil and
natural gas properties. Accordingly, the estimates are expected to change as
future information becomes available. The estimates have been prepared by
independent petroleum reservoir engineers except with regard to Gladstone which 
were prepared internally by Gladstone.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil
and Natural Gas Reserves

The Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
Oil and Natural Gas Reserves ("Standardized Measure") is a disclosure
requirement under Statement of Financial Accounting Standards No. 69.

The Standardized Measure does not purport to be, nor should it be interpreted to
present, the fair value of EXCO's oil and natural gas reserves. An estimate of
fair value would also take into account, among other things, the recovery of
reserves not presently classified as proved, the value of unproved properties,
and consideration of expected future economic and operating conditions.

Under the Standardized Measure, future cash flows are estimated by applying
year-end prices, adjusted for fixed and determinable escalations, to the
estimated future production of year-end proved reserves. Future cash inflows are
reduced by estimated future production costs, based on period-end costs, and
projected future development costs to determine pre-tax cash inflows. Future
income taxes are computed by applying the statutory rate (based on the current
tax law adjusted for permanent differences and tax credits) to the excess of
pre-tax net cash flows over EXCO's income tax basis of its oil and natural gas
properties. Future net cash flows are discounted using a 10% annual discount
rate to arrive at the Standardized Measure.

The pro forma Standardized Measure of discounted future net cash flows relating
to EXCO's proved oil and natural gas reserves at December 31, 1997, follows (in
thousands):

                     COMBINED CONDENSED FINANCIAL STATEMENTS


   
The future cash flows shown above include amounts attributable to nonproducing
reserves requiring approximately $1,150,000 of future development costs. If
these reserves are not developed, the standardized measure of discounted future
net cash flows as of December 31, 1997, shown above would be reduced
significantly.
    

Estimates of economically recoverable oil and natural gas reserves and of future
net revenues are based upon a number of variable factors and assumptions, all of
which are to some degree speculative and may vary considerably from actual
results. Therefore, actual production, revenues, taxes, development and
operating expenditures may not occur as estimated. The reserve data are
estimates only, are subject to many uncertainties and are based on data gained
from production histories and on assumptions as to geologic formations and other
matters. Actual quantities of oil and natural gas may differ materially from the
amounts estimated.

   
The weighted average prices of oil and natural gas at December 31, 1997, used in
the calculation of the pro forma Standardized Measure were $16.51 barrel and
$2.04 per Mcf, respectively.

                         REPORT OF INDEPENDENT AUDITORS


The Board of Directors and Shareholders
EXCO Resources, Inc.

We have audited the accompanying statements of operating revenues and direct
operating expenses of the Maverick County Properties (as defined in Note 1 to
the accompanying statements) for the years ended December 31, 1996 and 1997.
These statements are the responsibility of EXCO's management. Our responsibility
is to express an opinion on these statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the statements of operating revenues and
direct operating expenses are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the statements of operating revenues and direct operating expenses. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall statement presentation. We
believe that our audits provide a reasonable basis for our opinion.

The accompanying statements of operating revenues and direct operating expenses
were prepared for the purpose of complying with the rules and regulations of the
Securities and Exchange Commission and are not intended to be a complete
presentation of revenues and expenses of the Maverick County Properties.

In our opinion, the statements of operating revenues and direct operating
expenses referred to above present fairly, in all material respects, the
operating revenues and direct operating expenses of Maverick County Properties
for the years ended December 31, 1996 and 1997 in conformity with generally
accepted accounting principles.

1.       Basis of Presentation

On February 11, 1998, EXCO acquired from Osborne Oil Company, Gypsy Production
Company, and other working interest owners, certain oil and natural gas
properties in Maverick County, Texas (the "Maverick County Properties"). The
Maverick County Properties include 9 gross (7.0 net) producing wells and 2 gross
(1.87 net) non-producing wells which may require recompletions, workovers or
abandonment. The Maverick County Properties include 360 gross (280 net)
developed acres and 3,384 gross (2,843 net) undeveloped acres. The purchase
price consisted of cash of approximately $760,200.

The acquisition was funded through borrowings made under EXCO's credit facility
with NationsBank, and cash from working capital.

The accompanying financial statements present the operating revenues and direct
operating expenses of the Maverick County Properties. The operating revenues and
direct operating expenses presented herein relate only to the interests in the
producing oil and natural gas properties acquired and do not represent all of
the oil and natural gas operations of the sellers. Direct operating expenses
include the actual costs of maintaining the producing properties and their
production, but do not include charges for depletion, depreciation, and
amortization; federal and state income taxes; interest; or general and
administrative expenses. Presentation of complete historical financial
statements for the years ended December 31, 1996 and 1997 is not practicable
because the Maverick County Properties were not accounted for as a separate
entity; and therefore, such statements are not available. The operating revenues
and direct operating expenses for the periods presented may not be
representative of future operations.

Revenues in the accompanying statements of operating revenues and direct
operating expenses are recognized on the sales method. Direct operating expenses
are recognized on an accrual basis.

Reserve Quantity Information

The following table presents EXCO's estimate of the proved oil and natural gas
reserves of the Maverick County Properties, all of which are located in the
United States, as of December 31, 1997. EXCO emphasizes that reserve estimates
are inherently imprecise and that estimates of new discoveries are more
imprecise than those of producing oil and natural gas properties. Accordingly,
the estimates are expected to change as future information becomes available.
The estimates have been prepared by independent petroleum reservoir engineers.

among other things, the recovery of reserves not presently classified as proved,
the value of unproved properties, and consideration of expected future economic
and operating conditions.

Under the Standardized Measure, future cash flows are estimated by applying
year-end prices, adjusted for fixed and determinable escalations, to the
estimated future production of year-end proved reserves. Future cash flows are
reduced by estimated future production costs, based on period-end costs, and
projected future development costs to determine net cash inflows. The Maverick
County Properties are not a separate tax paying entity. Accordingly, the
Standardized Measure for the Maverick County Properties is presented before
deduction of income taxes. Future net cash flows are discounted using a 10%
annual discount rate to arrive at the Standardized Measure.

Estimates of economically recoverable oil and natural gas reserves and of future
net revenues are based upon a number of variable factors and assumptions, all of
which are to some degree speculative and may vary considerably from actual
results. Therefore, actual production, revenues, taxes, development and
operating expenditures may not occur as estimated. The reserve data are
estimates only, are subject to many uncertainties and are based on data gained
from production histories and on assumptions as to geologic formations and other
matters. Actual quantities of natural gas and oil may differ materially from the
amounts estimated.

The weighted average prices of oil and natural gas at December 31, 1997 used in
the calculation of the Standardized Measure were $17.00 per barrel and $1.86 per
Mcf, respectively.

                                December 31, 1997

   
1.       Summary of Significant Accounting Policies

Organization

Jacobi-Johnson, a Texas corporation, was formed in 1991. Jacobi-Johnson's
operations consist primarily of acquiring interests in producing oil and natural
gas properties located in the continental United States. Jacobi-Johnson also
acts as the operator on certain of these properties and receives overhead
reimbursement fees as a result.

Management Estimates

In preparing financial statements in conformity with generally accepted
accounting principles, Jacobi-Johnson is required to make estimates and
assumptions that affect the reported amounts of assets, liabilities, revenues
and expenses during the reporting period. Actual results may differ from
management's estimates.

Cash Equivalents

Jacobi-Johnson considers all highly liquid investments with maturities of 3
months or less when purchased to be cash equivalents.

Concentration of Credit Risk and Accounts Receivable

Financial instruments that potentially subject Jacobi-Johnson to concentration
of credit risk consist principally of cash and trade receivables. Jacobi-Johnson
places its cash with high credit quality financial institutions. Jacobi-Johnson
sells oil and natural gas to various customers. In addition, Jacobi-Johnson
participates with other parties in the drilling, completion, and operation of
oil and natural gas wells. Substantially all of Jacobi-Johnson's accounts
receivable are due from either purchasers of oil, natural gas, or natural gas
liquids or participants in oil and natural gas wells for which Jacobi-Johnson
serves as the operator. Generally, operators of oil and natural gas properties
have the right to offset future revenues against unpaid charges related to
operated wells. Oil and natural gas sales are generally unsecured. Credit losses
are provided for in the financial statements and have been within management's
expectations. The allowance for doubtful accounts receivable aggregated $0 at
December 31, 1996 and 1997.

Oil and Natural Gas Properties

Oil and natural gas properties are recorded at cost using the full cost method
of accounting, as prescribed by the Securities and Exchange Commission (the
"SEC"). Under the full cost method, all costs associated with the acquisition,
exploration or development of oil and natural gas properties are capitalized as
part of the full cost pool.

Depreciation, depletion, and amortization of evaluated oil and natural gas
properties are provided using the unit-of-production method based on total
proved reserves, as determined by independent petroleum reservoir engineers.

Sales, dispositions, and other oil and natural gas property retirements are
accounted for as adjustments to the full cost pool, with no recognition of gain
or loss unless such disposition would significantly alter the amortization rate.

Office and Field Equipment

Office and field equipment are capitalized at cost and depreciated on a
straight line basis over their estimated useful lives.

Revenue Recognition

Jacobi-Johnson uses the sales method of accounting for oil and gas revenues. 
Under the sales method, revenues are recognized on actual volumes of oil and 
gas sold to purchasers.

Overhead Reimbursement Fees

                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 1997

   
Fees from overhead charges billed to working interest owners, including
Jacobi-Johnson, of $139,450 and $154,350 for the years ended December 31, 1996
and 1997, respectively, have been classified as a reduction of general and
administrative expenses in the accompanying statements of operations.

Income Taxes

Deferred income taxes are accounted for using the liability method in accounting
for income taxes.

Earnings Per Share

In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share. Statement No. 128 replaced the calculation of primary and
fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All earnings per share amounts for all periods have been
presented, and where appropriate, restated, to conform to the Statement No. 128
requirements. The effect of the adoption of Statement No. 128 did not have a
material impact.

INTERIM FINANCIAL STATEMENT PRESENTATION

In management's opinion, the accompanying interim financial statements contain
all adjustments (consisting solely of normal recurring accruals) necessary to
present fairly the financial position of Jacobi-Johnson as of March 31, 1998,
the results of operations for the three month periods ended March 31, 1997 and
1998, and the cash flows for the three month periods ended March 31, 1997 and
1998.

The results of operations for the three months ended March 31, 1998, are not
necessarily indicative of the results expected for the full year.

2.       Long-Term Debt

Long-term debt is summarized as follows (in thousands):

</TABLE>
    

   
At December 31, 1997, the future minimum principal payments on Jacobi-Johnson's
long-term debt subsequent to December 31, 1998 were: $34,373 in 1999; $7,249 in
2000; $5,196 in 2001; and $5,150 in 2002, based on borrowings outstanding at
December 31, 1997.

Southside Bank Credit Agreement

On January 12, 1998, Jacobi-Johnson refinanced its existing credit agreement
with Southside Bank (the "Credit Agreement"). The Credit Agreement consists of
an installment loan with an original balance of $232,486. The maturity date of
the Credit Agreement is July 28, 1999.

The Credit Agreement provides for 18 total monthly payments of $13,864 each.
The interest is calculated at a fixed rate of 8.5% per annum.

Borrowings under the Credit Agreement are secured by a deed of trust on real
property owned by Jacobi-Johnson located in Polk County, Texas.

3.       Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
Jacobi-Johnson's deferred tax liabilities and assets are as follows (in
thousands):

4.       Related Party Transactions

The parents of one of the principal stockholders loaned $50,000 to
Jacobi-Johnson in 1997 upon the same terms and conditions as could be obtained
with unrelated parties. In addition, one of the stockholders loaned $68,248 to
Jacobi-Johnson in 1993. This note was converted to 711 shares of new
Jacobi-Johnson common stock in December 1996.

5.       Commitments and Contingencies

Rent expense was approximately $10,693 for each of the years ended December 31,
1996 and 1997. As of December 31, 1997, Jacobi-Johnson's operating lease expires
in February, 1998. The rent under the lease is $891 per month.

6.       Environmental Regulation

Various Federal, state and local laws and regulations covering discharge of
materials into the environment, or otherwise relating to the protection of the
environment, may affect Jacobi-Johnson's operations and costs of oil and natural
gas exploitation, development and production operations. It is not anticipated
that Jacobi-Johnson will be required in the near future to expend amounts
material in relation to the financial statements taken as a whole by reason of
environmental laws and regulations. Because such laws and regulations are
constantly being changed, Jacobi-Johnson is unable to predict the conditions and
other factors, over which Jacobi-Johnson does not exercise control, that may
give rise to environment liabilities.

7.       Subsequent Event

On May 8, 1998, EXCO acquired all of the outstanding common stock of
Jacobi-Johnson. The aggregate purchase price paid for the stock was $1,476,451,
subject to post-closing adjustments. The post-closing adjustments may include
adjustments if it is determined that the net working capital of Jacobi-Johnson
at Closing is different than at January 1, 1998, if determined within 90 days of
the Closing and for any title problems if the problems are discovered within 60
days of the Closing. The Sellers have agreed to indemnify EXCO for amounts
arising from any breach by Sellers, including environmental damages, to the
extent such amount exceeds $20,000. EXCO has agreed to indemnify the Sellers for
amounts arising from any breach by EXCO, to the extent such amount exceeds
$20,000. The acquisition was effective January 1, 1998. The amount of
consideration was determined through arm's length negotiations taking into
account estimates of recoverable reserves, current oil and natural gas prices,
the fair market value of other property and equipment, the amount of cash and
cash equivalents on hand, the collectibility and estimated payment timing of
accounts receivable and the amount of current and long-term liabilities. The
consideration consisted of $703,035 cash, 85,436 shares of EXCO Common Stock and
EXCO assumed approximately $260,800 of Jacobi-Johnson indebtedness.
Simultaneously with the Closing, EXCO paid in full all outstanding loans with
Southside Bank. EXCO obtained the cash for the purchase price and payoff of the
Southside Bank loans under its credit facility (the "Credit Facility") with
NationsBank of Texas, N.A. The Jacobi-Johnson Properties have been mortgaged
under the Credit Facility.

All of Jacobi-Johnson's oil and natural gas revenues are from proved developed
properties located in the United States.

Jacobi-Johnson's oil and natural gas production is sold to various purchasers.
During the year ended December 31, 1996, sales of oil and natural gas to 1
purchaser accounted for 67% of consolidated gross revenues. During the year
ended December 31, 1997, sales of oil and natural gas to 2 purchasers accounted
for 58% and 18% of consolidated gross revenues, respectively. Management
believes that the loss of these purchasers would not have a material impact on
Jacobi-Johnson's consolidated financial condition or results of operations.

In an effort to reduce the effects of the volatility of the price of crude oil
and natural gas on Jacobi-Johnson's operations, management has adopted a policy
of hedging oil and natural gas prices whenever such prices are in excess of the
prices anticipated in Jacobi-Johnson's operating budget and profit plan through
the use of commodity futures, options, and swap agreements. Hedging transactions
require the approval of the Board of Directors. There were no outstanding
contracts at December 31, 1997.

9.  Supplemental Oil and Natural Gas Reserve and Standardized Measure 
    Information (Unaudited)

Jacobi-Johnson currently retains independent engineering firms to provide annual
year-end estimates of Jacobi-Johnson's future net recoverable oil, natural gas,
and natural gas liquids reserves. Estimated proved net recoverable reserves as
shown below include only those quantities that can be expected to be
commercially recoverable at prices and costs in effect at the balance sheet
dates under existing regulatory practices and with conventional equipment and
operating methods. Proved developed reserves represent only those reserves to

reserves expected to be recovered from new wells on undrilled acreage or from
existing wells on which a relatively major expenditure is required for
recompletion.

The following is a summary of a standardized measure of discounted net cash
flows related to Jacobi-Johnson's proved oil, natural gas, and natural gas
liquids reserves. The information presented is based on a valuation of proved
reserves using discounted cash flows based on year-end prices, costs, and
economic conditions and a 10% discount rate. The additions to proved reserves
from new discoveries and extensions could vary significantly from year to year;
additionally, the impact of changes to reflect current prices and costs of
reserves proved in prior years could also be significant. Accordingly, the
information presented below should not be viewed as an estimate of the fair
value of Jacobi-Johnson's oil and natural gas properties, nor should it be
considered indicative of any trends.

During recent years, there have been significant fluctuations in the prices paid
for crude oil in the world markets. This situation has had a destabilizing
effect on crude oil's posted prices in the United States, including the posted
prices paid by purchasers of Jacobi-Johnson's crude oil. The weighted average
prices of oil and natural gas at December 31, 1996 and 1997, used in the above
table, were $24.80 and $15.97 per Bbl, respectively, and $3.48 and $2.12 per
Mcf, respectively.

The following are the principal sources of change in the standardized measure of
discounted future net cash flows:

                         REPORT OF INDEPENDENT AUDITORS


The Board of Directors and Shareholders
EXCO Resources, Inc.

We have audited the accompanying statements of operating revenues and direct
operating expenses of the Dawson County Properties (as defined in Note 1 to the
accompanying statements) for the years ended December 31, 1996 and 1997. These
statements are the responsibility of EXCO's management. Our responsibility is to
express an opinion on these statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the statements of operating revenues and
direct operating expenses are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the statements of operating revenues and direct operating expenses. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall statement presentation. We
believe that our audits provide a reasonable basis for our opinion.

The accompanying statements of operating revenues and direct operating expenses
were prepared for the purpose of complying with the rules and regulations of the
Securities and Exchange Commission and are not intended to be a complete
presentation of revenues and expenses of the Dawson County Properties.

In our opinion, the statements of operating revenues and direct operating
expenses referred to above present fairly, in all material respects, the
operating revenues and direct operating expenses of Dawson County Properties for
the years ended December 31, 1996 and 1997 in conformity with generally accepted
accounting principles.

                            DAWSON COUNTY PROPERTIES

                    NOTES TO STATEMENTS OF OPERATING REVENUES
                          AND DIRECT OPERATING EXPENSES

   
1.       Basis of Presentation

On May 29, 1998, EXCO executed a non-binding letter of intent to acquire from 
J.M. Hill, J.M. Hill, Trustee, Walter O. Hill, and Steven J. Devos, certain oil
and natural gas properties in Dawson and Brazos Counties, Texas (the "Dawson 
County Properties"). The Dawson County Properties include 11 gross (3.4 net) 
producing wells and 4 gross (.85 net) saltwater disposal and non-producing 
wells which may require recompletions, workovers or abandonment. The Dawson 
County Properties include 645 gross (251 net) developed acres and 889 gross 
(119 net) undeveloped acres. The purchase price is $1,364,000 cash.

The acquisition will be funded through borrowings made under EXCO's credit
facility with NationsBank, and cash from working capital.

The accompanying financial statements present the operating revenues and direct
operating expenses of the Dawson County Properties. The operating revenues and
direct operating expenses presented herein relate only to the interests in the
producing oil and natural gas properties to be acquired and do not represent all
of the oil and natural gas operations of the sellers. Direct operating expenses
include the actual costs of maintaining the producing properties and their
production, but do not include charges for depletion, depreciation, and
amortization; federal and state income taxes; interest; or general and
administrative expenses. Presentation of complete historical financial
statements for the years ended December 31, 1996 and 1997 is not practicable
because the Dawson County Properties were not accounted for as a separate
entity; and therefore, such statements are not available. The operating revenues
and direct operating expenses for the periods presented may not be
representative of future operations.

Revenues in the accompanying statements of operating revenues and direct
operating expenses are recognized on the sales method. Direct operating expenses
are recognized on an accrual basis.

In management's opinion, the accompanying interim financial statements contain
all adjustments (consisting solely of normal recurring accruals) necessary to
present fairly the financial position of Dawson County Properties as of March
31, 1998, the results of operations for the three month periods ended March 31,
1997 and 1998, and the cash flows for the three month periods ended March 31,
1997 and 1998.
    

   
    

   
The results of operations for the three months ended March 31, 1998, are not
necessarily indicative of the results expected for the full year.

2. Supplemental Oil and Natural Gas Reserve and Standardized Measure 
   Information (Unaudited)

Reserve Quantity Information

The following table presents EXCO's estimate of the proved oil and natural gas
reserves of the Dawson County Properties, all of which are located in the United
States, as of December 31, 1997. EXCO emphasizes that reserve estimates are
inherently imprecise and that estimates of new discoveries are more imprecise
than those of producing oil and natural gas properties. Accordingly, the
estimates are expected to change as future information becomes available. The
estimates have been prepared by independent petroleum reservoir engineers.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil
and Gas Reserves

                            DAWSON COUNTY PROPERTIES

                    NOTES TO STATEMENTS OF OPERATING REVENUES
                          AND DIRECT OPERATING EXPENSES

   
The Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
Oil and Gas Reserves ("Standardized Measure") is a disclosure requirement under
Statement of Financial Accounting Standards No. 69.

The Standardized Measure does not purport to be, nor should it be interpreted to
present, the fair value of the oil and natural gas reserves of the Dawson County
Properties. An estimate of fair value would also take into account, among other
things, the recovery of reserves not presently classified as proved, the value
of unproved properties, and consideration of expected future economic and
operating conditions.

Under the Standardized Measure, future cash flows are estimated by applying
year-end prices, adjusted for fixed and determinable escalations, to the
estimated future production of year-end proved reserves. Future cash flows are
reduced by estimated future production costs, based on period-end costs, and
projected future development costs to determine net cash inflows. The Dawson
County Properties are not a separate tax paying entity. Accordingly, the
Standardized Measure for the Dawson County Properties is presented before
deduction of income taxes. Future net cash flows are discounted using a 10%
annual discount rate to arrive at the Standardized Measure.

The Standardized Measure of discounted future net cash flows relating to proved
oil and natural gas reserves of the Dawson County Properties at December 31,
1997 follows (in thousands):

</TABLE>
    


   
Estimates of economically recoverable oil and natural gas reserves and of future
net revenues are based upon a number of variable factors and assumptions, all of
which are to some degree speculative and may vary considerably from actual
results. Therefore, actual production, revenues, taxes, development and
operating expenditures may not occur as estimated. The reserve data are
estimates only, are subject to many uncertainties and are based on data gained
from production histories and on assumptions as to geologic formations and other
matters. Actual quantities of natural gas and oil may differ materially from the
amounts estimated.
    

   
During 1996 and 1997 the Dawson County Properties incurred no developmental
or exploratory costs and there were no incremental general and administrative
costs.
    

   
The weighted average prices of oil and natural gas at December 31, 1997 used in
the calculation of the Standardized Measure were $17.03 per barrel and $1.89 per
Mcf, respectively.

ITEM 15.  Indemnification of Directors and Officers.

         EXCO has authority under Articles 2.02(A)(16) and 2.02-1 of the Texas
Business Corporation Act to indemnify its officers and directors to the extent
provided for in such statute.

         Article VI of EXCO's Restated Bylaws provides that EXCO shall indemnify
each of its directors and officers, its former directors and officers and agents
of EXCO against expenses actually and reasonably incurred by him or her in
connection with the defense of any action, suit or proceeding, civil or
criminal, in which such person is made a party by reason of being or having been
such director or officer, except in situations where he or she shall be adjudged
in such action, suit or proceeding to be liable for negligence or misconduct in
the performance of his or her duty to EXCO. In the event of a criminal
conviction (whether based on a plea of guilty or nolo contendere or its
equivalent, or after trial), such conviction shall not be deemed an adjudication
of liability for negligence or misconduct in the performance of duty to EXCO if
such director or officer acted in good faith in what he or she considered to be
the best interest of EXCO and without reasonable cause to believe that his or
her actions were illegal. In absence of an adjudication which expressly absolves
the director or officer of liability to EXCO or its shareholders for negligence
or misconduct, or in the event of a settlement, the right to indemnification of
a director or officer shall be conditioned upon prior resolution adopted by
two-thirds of the disinterested members of the Board or by independent counsel.

         EXCO intends to maintain insurance against any liability incurred by
its officers and directors in defense of any actions to which they are made
parties by reason of their positions as officers and directors.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Commission such indemnification is against
public policy as expressed in the Act and is therefore unenforceable.

ITEM 17.  Undertakings.

      1. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the Registrant's Restated Articles of Incorporation
or otherwise, the Registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that

                                      II-2

<PAGE>   120



a claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

      2. The undersigned registrant hereby undertakes that:

      To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

                (i)   to include any prospectus required by Section 10(a)(3) of 
      the Securities Act of 1933;

                (ii) to reflect in the prospectus any facts or events arising
      after the effective date of the Registration Statement (or the most recent
      post-effective amendment thereof) which, individually or in the aggregate,
      represent a fundamental change in the information set forth in the
      Registration Statement. Notwithstanding the foregoing, any increase or
      decrease in volume of securities offered (if the total dollar value of
      securities offered would not exceed that which was registered) and any
      deviation from the low or high end of the estimated maximum offering range
      may be reflected in the form of prospectus filed with the Commission
      pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than a 20% change in the maximum aggregate
      offering price set forth in the "Calculation of Registration Fee" table in
      the effective Registration Statement;

                (iii) to include any material information with respect to the
      plan of distribution not previously disclosed in the Registration
      Statement or any material change to such information in the Registration
      Statement;

provided, however, that paragraphs (i) and (ii) will not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in this Registration Statement.

      For the purpose of determining any liability under the Securities Act of
1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

      It will remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will , unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

      For purposes of determining any liability under the Securities Act of
1933, each filing of the registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.


                                      II-3

<PAGE>   121



   
       3.       The undersigned registrant hereby undertakes to supplement the 
prospectus, after the expiration of the subscription period, to set forth the
results of the subscription offer, the transactions by the underwriters during
the subscription period, the amount of unsubscribed securities to be purchased
by the underwriters, and the terms of any subsequent reoffering thereof. If any
public offering by the underwriters is to be made on terms differing from those
set forth on the cover page of the prospectus, a post-effective amendment will
be filed to set forth the terms of such offering.

behalf by the undersigned, thereunto duly authorized, in the City of Dallas,

         and to undertake or assume the whole or any part of the obligations or
         liabilities of any person, firm, association or corporation.

                  To have all of the powers and to do and perform every act and
         enjoy every privilege conferred upon corporations under and by virtue
         of Article 2.02 of the Texas Business Corporation Act, Chapter 64, Acts
         of the 54th Legislature of the State of Texas, Regular Session, 1995,
         subject to the limitations contained in Paragraphs B and C of said Act.

                  In general, to have and exercise all the powers conferred by
         the laws of Texas upon corporations formed under the Texas Business
         Corporation Act of the State of Texas, and do any or all of the things
         hereinbefore set forth to the same extent as natural persons might or
         could do.

         4. A. The aggregate number of shares of all classes of stock that the
corporation shall have authority to issue is Thirty-Five Million (35,000,000),
of which Twenty-Five Million (25,000,000) shares of the par value of $0.01 per
share shall be Common Stock and Ten Million (10,000,000) shares of the par value
of $0.01 per share shall be Preferred Stock issuable in series.

         B. Common Stock. Each five (5) shares of previously authorized Common
Stock of the corporation, par value $0.01 per share, issued and outstanding
immediately prior to the time of the filing and recording of the Articles of
Amendment to the Articles of Incorporation (the "Amendment") with the Office of
the Secretary of State of the State of Texas on July 19, 1996, shall thereby and
thereupon automatically be combined without any further action into one (1)
validly issued, fully paid and nonassessable share of Common Stock of the
corporation, par value $0.01 per share. Further, every right, option and warrant
to acquire five (5) shares of Common Stock of the corporation, outstanding
immediately prior to the time of filing and recording of the Amendment of the
Office of the Secretary of State of the State of Texas, shall thereby and
thereupon automatically be converted without any further action into the right
to acquire one (1) share of Common Stock of the corporation, upon the terms of
the right, option or warrant, except that the purchase price of the Common
Stock, upon exercising the right, option or warrant, shall be proportionately
increased. The corporation shall not issue fractional shares with respect to the
combination or conversion. To the extent that a shareholder holds a number of
shares of Common Stock immediately prior to the filing and recording of the
Amendment that is not evenly divisible by five (5), such shareholder shall
receive one additional share of Common Stock for each fractional share otherwise
issuable. As a result of the Amendment, the corporation's Common Stock account
will be reduced from (a) $0.01 multiplied by the number of shares of Common
Stock issued and outstanding prior to the filing and recording of the Amendment
to (b) $0.01 multiplied by the number of shares of Common Stock issued and
outstanding immediately after the filing and recording of the Amendment. The
Capital in excess of par value account will be credited with the amount by which
the

Common Stock account is reduced. The number of shares of authorized Common Stock
of the corporation will remain at 25,000,000 and will not be affected by the
Amendment.

         C. Preferred Stock. Shares of Preferred Stock may be issued from time
to time in one or more series, the shares of each series to have such
designations, powers, preferences, rights, qualifications, limitations and
restrictions as are stated and expressed herein and in the resolution or
resolutions providing for the issue of such series adopted by the Board of
Directors as hereafter provided.

         Authority is hereby expressly granted to the Board of Directors to
authorize the issuance of the Preferred Stock from time to time in one or more
series, and with respect to each series of the Preferred Stock, to fix and
determine by the resolution or resolutions from time to time adopted provided
for the issuance thereof the numbers of shares to constitute the series and the
designation thereof and any one or more of the following rights and preferences:
(i) the rate of dividend; (ii) the price at and terms and conditions on which
shares may be redeemed; (iii) the amount payable upon shares in the event of
involuntary liquidation; (iv) the amount payable upon shares in the event of
voluntary liquidation; (v) sinking fund provisions (if any) for the redemption
or repurchase of the shares; (vi) the terms and conditions on which shares may
be converted, if the shares of any series are issued with the privilege of
conversion; and (vii) voting rights (included the number of votes per share, the
matters on which the shares can vote, and the contingencies that make the voting
rights effective). The shares of each series of the Preferred Stock may vary
from the shares of any other series thereof in any or all of the foregoing
respects. The Board of Directors may increase the number of shares designated
for any existing series by adding to such series authorized and unissued shares
not designated for any other series. The Board of Directors may decrease the
number of shares designated for any existing series by subtracting from such
series unissued shares designated for such series, and the shares so subtracted
shall become authorized and unissued shares of Preferred Stock.

         5. The corporation will not commence business until it has received as
consideration for the issuance of its shares at least Fifty Thousand & No/100
($50,000.00) Dollars, being ten percent (10%) of the total capitalization of
said corporation consisting of money or property actually received by the
corporation.

         6. A. No holder of any shares of stock of the corporation shall have or
enjoy any preemptive right to acquire any additional or treasury shares of the
corporation.

         B. Each outstanding share of the capital stock of the corporation shall
be entitled to one vote on each matter submitted to a vote at a meeting of
shareholders and no shareholder shall have the right to cumulate his votes in
the election of directors of the corporation and such cumulative voting of
shares as provided in Section D of Article 2.29 of the Texas Business
Corporation Act is expressly prohibited.

         7. The registered offices of the corporation shall be at 9400 North
Central Expressway, Suite 1209, Dallas, Texas 75231, and the name of the
registered agent at such address is Glenn L. Seitz.

         is expressly provided for by statute, or

                  (5) an act related to an unlawful share repurchase or payment
         of a dividend.

If applicable law or regulations are amended after approval by the corporation's
shareholders of this Article 10 to authorize corporate action further
eliminating or limiting the personal liability of Directors or eliminating or
limiting the personal liability of officers, the liability of a Director or
officer of the corporation shall be eliminated or limited to the maximum extent
permitted by law. No repeal or modification of this Article 10 by the

                            ARTICLES OF AMENDMENT
                                   TO THE
                          ARTICLES OF INCORPORATION


        Pursuant to the provisions of article 4.04 of the Texas Business
Corporation Act, the undersigned corporation adopts the following articles of
amendment to its articles of incorporation:

        The following two amendments to the articles of incorporation were
adopted by the shareholders of the corporation on March 31, 1998. The first
amendment effects a one-for-two reverse stock split, maintains the number of
authorized shares of Common Stock, and doubles the par value of Common Stock
from $0.01 to $0.02 per share (the "Reverse Split Amendment"). The second
amendment allows the Board of Directors to fix the number of directors by
resolution of the Board of Directors (the "Board Size Amendment").

        The amendments alter or change Article Three of the restated articles
of incorporation and the full text of each provision altered is as follows:

                        "4.A.   The total number of shares of all classes of
        stock which the Corporation shall have the authority to issue is Thirty
        Five Million (35,000,000) shares of which Twenty Five Million           
        (25,000,000) shares, par value of $.02 per share, shall be Common Stock
        (hereinafter called "Common Stock") and Ten Million (10,000,000)
        shares, par value of $.01 per share, shall be Preferred Stock
        (hereinafter called "Preferred Stock").

                        B.      Each two shares of Common Stock, par value
        $0.01 per share, issued and outstanding at the close of business on the
        date of the filing of the Amendment to the Articles which incorporates
        this provision is hereby automatically and without further action
        reclassified, converted and combined into one fully paid and
        nonassessable share of Common Stock, par value $0.02 per share;
        provided, however, that no fractional shares of Common Stock shall
        be issued as a result of the reclassification, conversion and
        combination.  The Corporation shall issue to each shareholder of the
        Corporation otherwise entitled to receive a fractional share of Common
        Stock, cash in an amount equal to the product obtained by multiplying
        the fraction by the last bid price for the Common Stock on the OTC
        Bulletin Board on March 17, 1998 in lieu of a fractional share of
        Common Stock."

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 6.01 - Indemnification. This Corporation shall indemnify each
of its directors or officers or its former directors and officers or any person
who may have served at its request as a director or officer of another
corporation in which it owns shares of capital stock or of which it is a
creditor against expenses actually and reasonably incurred by him in connection
with the defense of any action, suit or proceeding, civil or criminal, in which
he is made a party by reason of being or having been such director or officer,
except in relation to matters as to which he shall be adjudged in such action,
suit or proceeding to be liable for negligence or misconduct in the performance
of his duty to such corporation. Negligence or misconduct for this purpose
shall be deemed to include willful misfeasance, bad faith, gross negligence or
the reckless disregard of the duties involved in the conduct of his office. A
conviction of judgment (whether based on a plea of guilty or nolo contendere or
its equivalent, or after trial) in a criminal action, suit or proceeding shall
not be deemed an adjudication of liability for negligence or misconduct in the
performance of duty to the Corporation if the director, officer or other person
acted in good faith in what he considered to be the best interests of the
Corporation and without reasonable cause to believe that the action upon which
the judgment of conviction is predicated was illegal. In the absence of an
adjudication which expressly absolves the director, officer or other person of
liability to the Corporation or its shareholders for negligence and misconduct
within the meaning thereof, as used herein, or in the event of a settlement the
right to indemnification of each director, officer or other person shall be
conditioned upon the prior determination by a resolution adopted by two-thirds
(2/3) of those members of the Board of Directors who are not involved in the
action, suit or proceeding that the director or officer has no liability by
reason of


RESTATED BYLAWS OF EXCO RESOURCES, INC. - PAGE 9
<PAGE>   10
negligence or misconduct, within the meaning thereof used herein, or, in the
alternative, if a majority of the Board of Directors are involved in the
action, suit or proceedings, such determination shall have been made by
independent counsel. The right to indemnification provided for herein shall
extend and include the heirs, personal representatives, executors and
administrators of any deceased officer, director or other person described
above.

         Section 6.02 - Indemnification in Securities Matters. In the event
that a claim for indemnification under the provisions of Section 6.01 hereof is
made for liabilities arising under the Securities Act of 1933, as amended and
supplemented, the indemnification shall not be made or allowed unless:

                  (1) the claim for indemnification under the circumstances is
         predicated upon the prior successful defense by the applicant of any
         action, suit or proceeding,

                  (2) the Board of Directors receives an opinion of counsel of
         the Corporation to the effect that it has been settled by controlling
         precedent that indemnification under the circumstances is not against
         public policy as expressed in said Act, or

                  (3) a court of appropriate jurisdiction finally adjudicates
         in an action, suit or proceeding in which the issue is submitted to
         the court by the Corporation prior to allowance of the claim that
         indemnification under the circumstances is not contrary to the public
         policy expressed in said Act.

         Section 6.03 - Types of Actions. The provisions of Sections 6.01 and
6.02 hereof shall apply to any action, suit or proceeding by or in the right of
the Corporation, as well as to other actions, suits or proceedings, whatsoever
the nature thereof or the claim or cause of action asserted therein.

         Section 6.04 - Other Rights. The right of indemnification provided for
in Sections 6.01 and 6.02 hereof shall be in amplification, and not in
limitation, of any other right, relief or remedy to which the directors,
officers and other persons referred to therein may be entitled according to
law.

         Section 6.05 - Reliance upon Counsel; Corporate Records. Every
officer, director or member of any committee appointed by the Board of
Directors shall, in the performance of his duties, be fully protected in
relying in good faith upon the opinion of counsel of the Corporation and upon
the books of account or reports made to the Corporation by any of its
officials, or by an independent certified public accountant, or by an appraiser
selected with reasonable care by the Board of Directors, or by such committee,

Dear Shareholder:

         You will find enclosed the Prospectus and other materials relating to
the rights offering by EXCO Resources, Inc. ("EXCO").

         We request that you carefully review the Prospectus which describes how
you may participate in the rights offering. As indicated in the Prospectus,
there is a limited period of time, up to and including the Expiration Date,
during which you will be able to either purchase additional shares or sell your
transferable rights.

SUMMARY OF THE TERMS OF THE OFFERING

   
         -        You will receive ten transferable rights for each share of
                  EXCO Common Stock you owned on the Record Date (June ___, 
                  1998).
    

         -        You may purchase one share of Common Stock for each right you
                  receive at the Subscription Price of $____ per share.

         -        Holders of rights who have fully exercised the rights issued
                  to them may subscribe for additional shares up to 100% of
                  their Basic Subscription Privilege through the
                  Oversubscription Privilege. If the number of shares purchased
                  in such oversubscriptions exceeds 5,943,360 shares when added
                  to the number of shares purchased pursuant to the Basic
                  Subscription Privilege, shares will be allocated to those
                  shareholders who oversubscribe, based upon the number of
                  shares such holders subscribed for pursuant to the Basic
                  Subscription Privilege, as more fully described in the
                  Prospectus.

         -        The rights offering expires at 5:00 p.m. Dallas time on
                  _____________, 1998.

         If your shares are held in your name, a Subscription Certificate is
enclosed. If your shares are held in the name of your bank or broker, you must
contact your bank or broker if you wish to participate in this offering.

         The rights will trade on the OTC Bulletin Board. Please decide if you
would like to (a) subscribe for additional shares, or (b) sell your rights.

         YOU ARE ENCOURAGED TO SUBSCRIBE FOR ADDITIONAL SHARES OR SELL YOUR
RIGHTS BECAUSE THOSE SHAREHOLDERS WHO DO NOT TAKE ANY ACTION WILL EXPERIENCE A
DILUTION IN THE VALUE OF THEIR SHARES OF EXCO COMMON STOCK AND A REDUCTION IN
THEIR PROPORTIONATE INTEREST IN EXCO.

         On behalf of the Board of Directors, we thank you for your support and
confidence and look forward to continuing to serve you.

                                       Sincerely,


                                       DOUGLAS H. MILLER
                                       Chairman and Chief Executive Officer

         If you have any questions concerning the rights offering, please feel
free to contact Richard E. Miller, Secretary and General Counsel, at (214)

                 INSTRUCTIONS AS TO USE OF EXCO RESOURCES, INC.
                            SUBSCRIPTION CERTIFICATES

               CONSULT CONTINENTAL STOCK TRANSFER & TRUST COMPANY,
                     YOUR BANK OR BROKER AS TO ANY QUESTIONS

   
         The following instructions relate to a rights offering (the "Rights
Offering") by EXCO Resources, Inc., a Texas corporation ("EXCO"), to the holders
of its Common Stock, par value $.02 per share ("Common Stock"), as described in
EXCO's Prospectus dated _______________, 1998, (the "Prospectus"). Holders of
record of Common Stock at the close of business on June __, 1998 (the "Record
Date") are receiving ten transferable subscription rights (the "Rights") for
each share of Common Stock held by them as of the close of business on the
Record Date. An aggregate of approximately 5,943,360 Rights exercisable to
purchase an aggregate of approximately 5,943,360 shares (the "Rights Shares") of
the Common Stock of EXCO are being distributed in connection with the Rights
Offering. Each Right is exercisable, upon payment of $____ in cash (the
"Subscription Price"), to purchase one share of Common Stock (the "Basic
Subscription Privilege"). In addition, subject to the allocation described
below, each Right also carries the right to subscribe at the Subscription Price
for additional shares of Common Stock available as a result of unexercised
Rights, if any (the "Oversubscription Privilege"), up to the maximum amount
offered by EXCO as described in the Prospectus. Rights Shares will be available
for purchase pursuant to the Oversubscription Privilege only to the extent that
all the Rights Shares are not subscribed for through the exercise of the Basic
Subscription Privilege by the Expiration Date (as defined below). If the Rights
Shares so available taking into account the restrictions in the prospectus (the
"Excess Shares") are not sufficient to satisfy all subscriptions pursuant to the
Oversubscription Privilege, the available Excess Shares will be allocated pro
rata (subject to the elimination of fractional shares) among the holders of
Rights who exercise the Oversubscription Privilege, in proportion, not to the
number of shares requested pursuant to the Oversubscription Privilege, but to
the number of shares each beneficial holder has purchased pursuant to the Basic
Subscription Privilege; provided, however, that if such pro rata allocation
results in any holder being allocated a greater number of Excess Shares than
such holder subscribed for pursuant to the exercise of such holder's
Oversubscription Privilege, then such holder will be allocated only such number
of Excess Shares as such holder subscribed for and the remaining Excess Shares
will be allocated among all other holders exercising the Oversubscription
Privilege. See "The Rights Offering -- Subscription Privileges" in the
Prospectus.
    

         No fractional Rights or cash in lieu thereof will be issued or paid.
The number of Rights distributed to each record holder has been rounded up to
the nearest whole number in order to avoid issuing fractional Rights.

         The Rights will expire at 5:00 p.m., Dallas time, on _____________,
1998, unless extended by EXCO (as it may be extended, the "Expiration Date").
The Rights are expected to be traded on the OTC Bulletin Board (the "OTC") until
close of business on the last OTC trading day preceding the Expiration Date.

         The number of Rights to which you are entitled is printed on the face
of your Subscription Certificate. You should indicate your wishes with regard to
the exercise or transfer of your Rights by completing the appropriate form or
forms on the back of your Subscription Certificate and returning the
Subscription Certificate to the Subscription Agent in the envelope provided.

         YOUR SUBSCRIPTION CERTIFICATES MUST BE RECEIVED BY THE SUBSCRIPTION
AGENT, OR GUARANTEED DELIVERY REQUIREMENTS WITH RESPECT TO YOUR SUBSCRIPTION
CERTIFICATES MUST BE COMPLIED WITH, AND PAYMENT OF THE SUBSCRIPTION PRICE FOR
ALL RIGHTS EXERCISED INCLUDING OVERSUBSCRIPTION SHARES, INCLUDING FINAL
CLEARANCE OF ANY CHECKS, MUST BE RECEIVED BY THE SUBSCRIPTION AGENT, ON OR
BEFORE THE EXPIRATION DATE. ONCE A HOLDER OF RIGHTS HAS EXERCISED THE BASIC
SUBSCRIPTION PRIVILEGE AND/OR THE OVERSUBSCRIPTION PRIVILEGE, SUCH EXERCISE MAY
NOT BE REVOKED.


<PAGE>   2
1.       SUBSCRIPTION PRIVILEGES.

         To exercise Rights, complete Section 1 of the Subscription Certificate
and send your properly completed and executed Subscription Certificate, together
with payment in full of the Subscription Price for each Rights Share subscribed
for pursuant to the Basic Subscription Privilege and the Oversubscription
Privilege, to the Subscription Agent. All payments must be made in United States
dollars by (i) check or bank draft drawn upon a United States bank or postal,
telegraphic or express money order payable to "Continental Stock Transfer, as
Subscription Agent"; or (ii) wire transfer of funds to the account maintained by
the Subscription Agent for such purpose at Chase Manhattan, Account No.
777-009625, ABA No. 021000021; or (iii) in the case of persons acquiring Rights
Shares at an aggregate Subscription Price of $1.5 million or more, an Approved
Payment Method as defined in the Prospectus. Payments will be deemed to have
been received by the Subscription Agent only upon the (a) clearance of any
uncertified check, (b) receipt by the Subscription Agent of any certified check
or bank draft drawn upon a United States bank or postal, telegraphic or express
money order, (c) the receipt of good funds in the Subscription Agent's account
designated above, or (d) receipt of funds by the Subscription Agent through an
Approved Payment Method. IF PAYING BY UNCERTIFIED PERSONAL CHECK, PLEASE NOTE
THAT THE FUNDS PAID THEREBY MAY TAKE AT LEAST FIVE BUSINESS DAYS TO CLEAR.
ACCORDINGLY, HOLDERS OF RIGHTS WHO WISH TO PAY THE SUBSCRIPTION PRICE BY MEANS
OF UNCERTIFIED PERSONAL CHECK ARE URGED TO MAKE PAYMENT SUFFICIENTLY IN ADVANCE
OF THE EXPIRATION DATE TO ENSURE THAT SUCH PAYMENT IS RECEIVED AND CLEARS BY
SUCH DATE, AND ARE URGED TO CONSIDER PAYMENT BY MEANS OF CERTIFIED OR CASHIER'S
CHECK, MONEY ORDER OR WIRE TRANSFER OF FUNDS. You may also transfer your
Subscription Certificate to your bank or broker in accordance with the
procedures specified in Instruction 3(a) below, make arrangements for the
delivery of funds on your behalf and request such bank or broker to exercise the
Rights represented by such Subscription Certificate on your behalf.
Alternatively, you may cause a written guarantee substantially in the form
available from the Subscription Agent (the "Notice of Guaranteed Delivery") from
a member firm of a registered national securities exchange or a member of the
National Association of Securities Dealers, Inc. or a commercial bank or trust
company having an office or correspondent in the United States, to be received
by the Subscription Agent on or prior to the Expiration Date guaranteeing
delivery of your properly completed and executed Subscription Certificate within
three OTC trading days following the date of the Notice of Guaranteed Delivery.
If this procedure is followed, your Subscription Certificates must be received
by the Subscription Agent within three OTC trading days of the Notice of
Guaranteed Delivery. Additional copies of the Notice of Guaranteed Delivery may
be obtained upon request from the Subscription Agent at the address, or by
calling the telephone number, indicated below.

         Banks, brokers and other nominee holders of Rights who exercise the
Basic Subscription Privilege and the Oversubscription Privilege on behalf of
beneficial owners of Rights will be required to certify to the Subscription
Agent and EXCO (by delivery to the Subscription Agent of a Nominee Holder
Certificate substantially in the form available from the Subscription Agent), as
to the aggregate number of Rights that have been exercised, and the number of
Rights Shares that are being subscribed for pursuant to the Oversubscription
Privilege, by each beneficial owner of Rights (including such nominee itself) on
whose behalf such nominee holder is acting. In the event a Nominee Holder
Certification is not delivered in respect of a Subscription Certificate, the
Subscription Agent shall for all purposes (including for purposes of any
allocation in connection with the Oversubscription Privilege) be entitled to
assume that such certificate is exercised on behalf of a single beneficial
owner. If more Excess Shares are subscribed for pursuant to the Oversubscription
Privilege than are available for sale, Excess Shares will be allocated, as
described above, among beneficial owners exercising the Oversubscription

         If you exercise less than all of the Rights evidenced by your
Subscription Certificate by so indicating in Section 1 of your Subscription
Certificate, the Subscription Agent either (i) will issue to you a new
Subscription Certificate evidencing the unexercised Rights or (ii) if you so
indicate in Section 2 of your Subscription Certificate, will transfer the
unexercised Rights in accordance with your instructions. However, if you choose
to have a new Subscription Certificate sent to you or to a transferee, you or
such transferee may not receive any such new Subscription Certificate in
sufficient time to permit sale or exercise of the Rights evidenced thereby. If
you have not indicated the number of Rights being exercised, or if the dollar
amount you have forwarded is not sufficient (subject to the second sentence of
Section 1 above) to purchase (or exceeds the amount necessary to purchase) the
number of shares subscribed for, you will be deemed to have exercised the Basic
Subscription Privilege with respect to the maximum number of whole Rights which
may be exercised for the Subscription Price payment delivered by you, and, to
the extent that the Subscription Price payment delivered by you exceeds the
product of the Subscription Price multiplied by the number of Rights evidenced
by the Subscription Certificates delivered by you (such excess being the
"Subscription Excess"), you will be deemed to have exercised your
Oversubscription Privilege to purchase, to the extent available, that number of
whole shares of Common Stock equal to the quotient obtained by dividing the
Subscription Excess by the Subscription Price.

2.       DELIVERY OF STOCK CERTIFICATES, ETC.

         The following deliveries and payments will be made to the address shown
on the face of your Subscription Certificate unless you provide instructions to
the contrary in Section 1 of your Subscription Certificate.

                  (a) Basic Subscription Privilege. As soon as practicable after
         the valid exercise of Rights and the Expiration Date, the Subscription
         Agent will mail to each exercising Rights holder certificates
         representing shares of Common Stock purchased pursuant to the Basic
         Subscription Privilege.

                  (b) Oversubscription Privilege. As soon as practicable after
         the Expiration Date and after all prorations and adjustments
         contemplated by the terms of the Rights Offering have been effected,
         the Subscription Agent will mail to each Rights holder who validly
         exercises the Oversubscription Privilege the number of shares allocated
         to such Rights holder pursuant to the Oversubscription Privilege. See
         "The Rights Offering -- Subscription Privileges -- Oversubscription
         Privilege" in the Prospectus.


<PAGE>   4
                  (c) Excess Payments. As soon as practicable after the
         Expiration Date and after all prorations and adjustments contemplated
         by the terms of the Rights Offering have been effected, the
         Subscription Agent will mail to each Rights holder who exercises the
         Oversubscription Privilege any excess funds received (without interest
         or deduction) in payment of the Subscription Price for Excess Shares
         that are subscribed for by such Rights holder but not allocated to such
         Rights holder pursuant to the Oversubscription Privilege.

3.       TO SELL OR TRANSFER RIGHTS.

                  (a) Sale of Rights Through a Bank or Broker. To sell all
         Rights evidenced by a Subscription Certificate through your bank or
         broker, so indicate in Section 1 of your Subscription Certificate and
         deliver your properly completed and executed Subscription Certificate
         to your bank or broker. If Section 1 of your Subscription Certificate
         is completed without designating a transferee, the Subscription Agent
         may thereafter treat the bearer of the Subscription Certificate as the
         absolute owner of all of the Rights evidenced by such Subscription
         Certificate for all purposes, and the Subscription Agent shall not be
         affected by any notice to the contrary. Because your bank or broker
         cannot issue Subscription Certificates, if you wish to sell less than
         all of the Rights evidenced by a Subscription Certificate, either you
         or your bank or broker must instruct the Subscription Agent as to the
         action to be taken with respect to the Rights not sold, or you or your
         bank or broker must first have your Subscription Certificate divided
         into Subscription Certificates of appropriate denominations by
         following the procedures set forth in Instruction 4 below. The
         Subscription Certificates evidencing the number of Rights you intend to
         sell can then be transferred by your bank or broker in accordance with
         the instructions in this Instruction 3(a).

                  (b) Transfer of Rights to a Designated Transferee. To transfer
         all of your Rights to a transferee other than a bank or broker, you
         must complete Section 2 of your Subscription Certificate in its
         entirety, execute the Subscription Certificate and have your signature
         guaranteed by an Eligible Guarantor Institution (as defined in Rule
         17Ad-15 of the Securities Exchange Act of 1934), subject to the
         standards and procedures adopted by the Subscription Agent. A
         Subscription Certificate that has been properly transferred in its
         entirety may be exercised by a new holder without having a new
         Subscription Certificate issued. In order to exercise, or otherwise
         take action with respect to, such a transferred Subscription
         Certificate, the new holder should deliver the Subscription
         Certificate, together with payment of the applicable Subscription Price
         (with respect to the exercise of both the Basic Subscription Privilege
         and the Oversubscription Privilege) and complete separate instructions
         signed by the new holder, to the Subscription Agent in ample time to
         permit the Subscription Agent to take the desired action. Because only
         the Subscription Agent can issue Subscription Certificates, if you wish
         to transfer less than all of the Rights evidenced by your Subscription
         Certificate to a designated transferee, you must instruct the
         Subscription Agent as to the action to be taken with respect to the
         Rights not sold or transferred, or you must divide your Subscription
         Certificate into Subscription Certificates of appropriate smaller
         denominations by following the procedures set forth in Instruction 4
         below. The Subscription Certificate evidencing the number of Rights you
         intend to transfer can then be transferred by following the procedures
         set forth in this Instruction 3(b).

4.       TO HAVE A SUBSCRIPTION CERTIFICATE DIVIDED INTO SMALLER DENOMINATIONS.

         To have a Subscription Certificate divided into smaller denominations,
send your Subscription Certificate, together with complete separate instructions
(including specification of the denominations into which you wish your Rights to
be divided) signed by you, to the Subscription Agent, allowing a sufficient
amount of time for new Subscription Certificates to be issued and returned so
that they can be used prior to the Expiration Date. Alternatively, you may ask a
bank or broker to effect such actions on your behalf. Your signature must be
guaranteed by an Eligible Guarantor Institution if any of the new Subscription
Certificates are to be issued in a name other than that in which the old
Subscription Certificate was issued. Subscription Certificates may not be
divided into fractional Rights, and any instruction to do so will be rejected.
As a result of delays in the mail, the time of the transmittal, the necessary
processing time and other factors, you or your transferee may not receive such
new Subscription


<PAGE>   5
Certificates in time to enable the Rights holder to complete a sale or exercise
by the Expiration Date. Neither EXCO nor the Subscription Agent will be liable
to either a transferor or transferee for any such delays.

5.       EXECUTION.

                  (a) Execution by Registered Holder. The signature on the
         Subscription Certificate must correspond with the name of the
         registered holder exactly as it appears on the face of the Subscription
         Certificate without any alteration or change whatsoever. Persons who
         sign the Subscription Certificate in a representative or other
         fiduciary capacity must indicate their capacity when signing and,
         unless waived by the Subscription Agent in its sole and absolute
         discretion, must present to the Subscription Agent satisfactory
         evidence of their authority so to act.

                  (b) Execution by Person Other than Registered Holder. If the
         Subscription Certificate is executed by a person other than the holder
         named on the face of the Subscription Certificate, proper evidence of
         authority of the person executing the Subscription Certificate must
         accompany the same unless the Subscription Agent, in its discretion,
         dispenses with proof of authority.

                  (c) Signature Guarantees. Your signature must be guaranteed by
         an Eligible Guarantor Institution if you wish to transfer your Rights,
         as specified in Instruction 3(b) above, to a transferee other than a
         bank or broker, if you wish a new Subscription Certificate or
         Certificates to be issued in a name other than that in which the old
         Subscription Certificate was issued, as specified in Instruction 4
         above, or if you specify special payment or delivery instructions
         pursuant to Section 2 of your Subscription Certificate.

6.       METHOD OF DELIVERY.

         The method of delivery of Subscription Certificates and payment of the
Subscription Price to the Subscription Agent will be at the election and risk of
the Rights holder. If sent by mail, it is recommended that they be sent by
registered mail, properly insured, with return receipt requested, and that a
sufficient number of days be allowed to ensure delivery to the Subscription
Agent and the clearance of any checks sent in payment of the Subscription Price
prior to the Expiration Date.

7.       SPECIAL PROVISIONS RELATING TO THE DELIVERY OF RIGHTS THROUGH
         DEPOSITORY FACILITY PARTICIPANTS.

         In the case of holders of Rights that are held of record through The
Depository Trust Company, Midwest Securities Trust Company, Philadelphia
Depository Trust Company or any other depository (each a "Depository"),
exercises of the Basic Subscription Privilege and the Oversubscription Privilege
may be effected by instructing the Depository to transfer Rights (such Rights,
"Depository Rights") from the Depository account of such holder to the
Depository account of the Subscription Agent, together with payment of the
Subscription Price for each Underlying Share subscribed for pursuant to the
Basic Subscription Privilege and the Oversubscription Privilege.

8.       SUBSTITUTE FORM W-9.

         Each Rights holder who elects to exercise Rights must provide the
Subscription Agent with a correct Taxpayer Identification Number ("TIN") on
Substitute Form W-9, substantially in the form provided with these instructions.
A copy of Substitute Form W-9 may be obtained upon request from the Subscription
Agent at the address indicated above. Failure to provide the information on the
form may subject such holder to a $50.00 penalty and to 31% back-up federal
income tax withholding with respect to dividends that may be paid by EXCO on
shares of Common Stock purchased upon the exercise of Rights and any payments
that may be remitted to Rights holders by the Subscription Agent in respect of
Rights sold on such holders' behalf by the Subscription Agent.

                             ________________, 1998

To Our Clients:

   
         We are enclosing for your consideration a Prospectus dated __________,
1998 describing the issuance to shareholders of record as of the close of
business on June __, 1998 of transferable rights ("Rights") to purchase at the
subscription price shares of Common Stock ("Common Stock") of EXCO Resources,
Inc. ("EXCO").
    

         Your attention is directed to the following:

         -        Shareholders will receive ten transferable Rights for each
                  share of Common Stock of EXCO held as of the close of business
                  on the Record Date. No fractional rights or cash in lieu
                  thereof will be paid, and the number of Rights distributed to
                  each holder of Common Stock will be rounded up to the nearest
                  whole number of Rights.

         -        Rights will be admitted for trading on the OTC Bulletin Board,
                  on which EXCO's Common Stock is traded. Assuming a market
                  exists, Rights may be purchased or sold through normal
                  brokerage channels or sold through the Subscription Agent up
                  to the last trading day prior to the Expiration Date,
                  ____________, 1998, as more fully described in the Prospectus.

         -        Basic Subscription Privilege: One Right will entitle the 
                  holder to purchase one share of Common Stock of EXCO at the
                  subscription price of $____ per share.

         -        Oversubscription Privilege: Any holder of Rights who fully
                  exercises all Rights held by him is entitled to subscribe at
                  the subscription price for shares that were not otherwise
                  subscribed for during the basic subscription. However, if such
                  oversubscriptions exceed the number of shares available, the
                  shares available will be allocated among those who
                  oversubscribed based on the number of shares subscribed for by
                  such holder pursuant to the basic subscription privilege, as
                  more fully described in the Prospectus.

         -        The expiration date of the rights offering is 5:00 p.m. Dallas
                  time, on ___________, 1998, unless extended by EXCO.

         Since we are the holder of record of the shares of Common Stock of EXCO
held in your Account, we have received your transferable Rights. We will
exercise or sell your Rights only in accordance with your instructions. IF YOU
DO NOT GIVE US YOUR INSTRUCTIONS, YOUR RIGHTS WILL BECOME VALUELESS AFTER THE
EXPIRATION DATE.

         Please forward your instructions to us immediately by completing the
form on the reverse side. Your Rights will expire at 5:00 p.m. Dallas time,
_____________, 1998, unless the rights offering is extended by EXCO.

                         FORM OF GUIDELINES TO FORM W-9

                           IMPORTANT TAX INFORMATION

         Under the federal income tax law, (i) dividend payments that may be
made by EXCO Resources, Inc. ("EXCO") on shares of Common Stock issued upon the
exercise of Rights and (ii) payments that may be remitted by the Subscription
Agent to Rights holders in respect of Rights sold on such holders' behalf by
the Subscription Agent, may be subject to backup withholding. Generally, such
payments will be subject to backup withholding unless (a) the holder is exempt
from backup withholding or (b) the holder furnishes the payer with his correct
tax identification number and certifies that the number provided is correct
and, in the case of backup withholding on dividend payments, the holder further
certifies that such holder is not subject to backup withholding due to prior
underreporting of interest or dividend income. Each Rights holder who either
exercises Rights or requests the Subscription Agent to sell Rights and wishes
to avoid backup withholding must provide the Subscription Agent (as EXCO's
agent, in respect of exercised Rights, and as payer with respect to Rights sold
by the Subscription Agent) with such Rights holder's correct taxpayer
identification number (or with a certification that such Rights holder is
awaiting a taxpayer identification number) and with a certification that such
Rights holder is not subject to backup withholding, by completing Substitute
Form W-9 below.

         Exempt Rights holders (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. In general, in order for a foreign individual to
qualify as an exempt recipient, the Rights holder must submit a statement,
signed under the penalties of perjury, attesting to that individual's exempt
status. The form of such statements can be obtained from the Subscription
Agent. Exempt Rights holders, while not required to file, should file
Substitute Form W-9 to avoid possible erroneous backup withholding. See the
enclosed Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9 for additional instructions.

         If backup withholding applies, EXCO or the Subscription Agent, as the
case may be, will be required to withhold 31% of any such payments made to the
Rights holder. Backup withholding is not an additional tax. Rather, persons
subject to backup withholding are entitled to credit the amount of tax withheld
against their actual tax liability. If withholding results in an overpayment of
taxes, a refund may be obtained.

PURPOSE OF SUBSTITUTE FORM W-9

         To prevent backup withholding on payments remitted by the Subscription
Agent with respect to Rights sold, the Rights holder is required to notify the
Subscription Agent of his correct taxpayer identification number by completing
the form below certifying that the taxpayer identification number provided on
Substitute Form W-9 is correct (or that such Rights holder is awaiting a
taxpayer identification number). To prevent backup withholding on dividend
payments, the Rights holder must, in addition, certify on Substitute Form W-9
that he is not subject to backup withholding due to prior underreporting of
interest or dividend income.

WHAT NUMBER TO GIVE THE SUBSCRIPTION AGENT

         The Rights holder is required to give the Subscription Agent the
taxpayer identification number of the record owner of the Rights. If such
record owner is an individual, the taxpayer identification number is his social
security number. If the Rights are held in more than one name or are not in the
name of the actual owner, consult the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional guidelines
on which number to report. If the Subscription Agent is not provided with the
correct taxpayer identification number in connection with such payments, the
Rights holder may be subject to a $50 penalty imposed by the Internal Revenue
Service.

PART III -- CERTIFICATION -- Under penalties of perjury, I certify that:

(1)      The number shown on this form is my correct Taxpayer Identification
         Number (or I am waiting for a number to be issued to me), and

(2)      I am not subject to backup withholding because (a) I have not been
         notified by the Internal Revenue Service ("IRS") that I am subject to
         backup withholding as a result of a failure to report all interest or
         dividends, or (b) the IRS has notified me that I am no longer subject
         to backup withholding.

Certification Guidelines -- You must cross out item (2) above if you have been
notified by the IRS that you are subject to backup withholding because of
underreporting interest or dividends on your tax return. However, if after
being notified by the IRS that you are subject to backup withholding you
received another notification from the IRS that you are no longer subject to
backup withholding, do not cross out item (2).

                         NUMBER ON SUBSTITUTE FORM W-9

SPECIFIC INSTRUCTIONS

NAME

If you are an individual, you must generally enter the name shown on your
social security card. However, if you have changed your last name, for
instance, due to marriage, without informing the Social Security Administration
of the name change, please enter your first name, the last name shown on your
social security card, and your new last name. If you are a sole proprietor, you
must enter your individual name. (Enter either your Social Security Number or
Employer Identification Number in Part I.) You may also enter your business
name or "doing business as" name on the business name line. Enter your name as
shown on your social security card and business name as it was used to apply
for your Employer Identification Number on Form SS-4.

PART I -- TAXPAYER IDENTIFICATION NUMBER (TIN)

You must enter your TIN in the appropriate box. If you are a sole proprietor,
you may enter your Social Security Number or Employer Identification Number.
Also see the chart under "Guidelines for Determining Proper Identification
Number to Give to Payer," below, for further clarification of name and TIN
combinations. If you do not have a TIN, follow the instructions under "How To
Obtain a TIN" below.

PART II -- FOR PAYEES EXEMPT FROM BACKUP WITHHOLDING

Individuals (including sole proprietors) are not exempt from backup
withholding. Corporations are exempt from backup withholding for certain
payments, such as interest and dividends. For a complete list of exempt payees,
see "Payees Exempt from Backup Withholding" below.

If you are exempt from backup withholding, you should still complete this form
to avoid possible erroneous backup withholding. Enter your complete TIN in Part
I, write "Exempt" in Part II, and sign and date the form. If you are a
nonresident alien or a foreign entity not subject to backup withholding, give
the payer a completed Form W-8, Certificate of Foreign Status.

PART III -- CERTIFICATION

For a joint account, only the person whose TIN is shown in Part I should sign.

1.       INTEREST, DIVIDENDS, AND PAYMENTS OF PROCEEDS RECEIVED BY OR THROUGH A
         BROKER. You must sign the certification or backup withholding will
         apply with respect to any dividend or interest payments that you
         receive. If you are subject to backup withholding and you are merely
         providing your correct TIN to the payer, you must cross out item 2 in
         the certification before signing the form.

2.       OTHER PAYMENTS. You must give your correct TIN, but you do not have to
         sign the certification unless you have been notified of an incorrect
         TIN. Other payments include payments made in the course of the payer's
         trade or business for rents, royalties to a nonemployee for services
         (including attorney and accounting fees), and payments to certain
         fishing boat crew members.

PRIVACY ACT NOTICE

Section 6109 requires you to give your correct TIN to persons who must file
information returns with the IRS to report interest, dividends, and certain
other income paid to you, mortgage interest you paid, the acquisition or
abandonment of secured property, cancellation of debt, or contributions you
made to an IRA. The IRS uses the numbers for identification purposes and to
help verify the accuracy of your tax return. You must provide your TIN whether
or not you are required to file a tax return. Payers must generally withhold
31% of taxable interest, dividend, and certain other payments to a payee who
does not give a TIN to a payer. Certain penalties may also apply.

                         NUMBER ON SUBSTITUTE FORM W-9

HOW TO OBTAIN A TIN

If you don't have a taxpayer identification number, apply for one immediately.
To apply, obtain Form SS-5, Application for a Social Security Number Card, or
Form SS-4, Application for Employer Identification Number, at the local post
office of the Social Security Administration or the Internal Revenue Service.

If you do not have a TIN, write "Applied For" in the space for the TIN in Part
I, sign and date the form, and give it to the payer. Generally, you will then
have 60 days to get a TIN and give it to the payer. If the payer does not
receive your TIN within 60 days, backup withholding, if applicable, will begin
and continue until you furnish your TIN.

NOTE: Writing "Applied For" on the form means that you have already applied for
a TIN or that you intend to apply for one soon. As soon as you receive your
TIN, complete another Form W-9, include your TIN, sign and date the form, and
send it to the payer.

Re:
Registration Statement in respect of 5,943,360 Rights to purchase Common Stock
and 5,943,360 shares of Common Stock, par value $.02 per share, of EXCO
Resources, Inc. ("Common Stock")

Gentlemen:

We are securities counsel to EXCO Resources, Inc., a Texas corporation (the
"Company"), in connection with the registration and issuance of up to 5,943,360
shares of Common Stock (the "Shares") issuable on exercise of 5,943,360 Rights
issuable to the Company's existing shareholders to purchase the Company's Common
Stock as described in the Prospectus.
    

We have examined such documents, records and matters of law as we have deemed
necessary for purposes of this opinion. Based on the foregoing, we are of the
opinion that the Rights and Shares are duly authorized and, when the Shares are
issued to the shareholders upon exercise of the Rights in accordance with their
respective terms and as described in the Prospectus contained in the Company's
Registration Statement to which this opinion is an exhibit, the Shares will be
validly issued, fully paid and nonassessable.

In rendering the foregoing opinion, we have relied as to certain factual matters
upon certificates of officers of the Company and public officials, and we have
not independently checked or verified the accuracy of the statements contained
therein.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement filed by the Company to effect registration of the Shares
under the Securities Act of 1933, as amended, and to the reference to us under
the caption "Legal Matters" in the Prospectus constituting a part of such
Registration Statement.


Very truly yours

                [FORM OF HAYNES AND BOONE, LLP'S TAX OPINION]



   
June ___, 1998
    



EXCO Resources, Inc.
5735 Pineland Drive, Suite 235
Dallas, Texas 75231

Re:    Distribution by EXCO Resources, Inc. of Rights to Purchase Common Stock

Ladies and Gentlemen:

We have acted as counsel to EXCO Resources, Inc. (the "Company") in connection
with the distribution to holders of its common stock (the "Existing
Shareholders") of rights to purchase common stock, par value $.02 per share (the
"Rights"), of the Company (the "Rights Offering").

   
You have requested our opinion as to the material United States federal income
tax consequences of the Rights Offering. In preparing our opinion, we have
reviewed and relied upon the Company's Registration Statement on Form S-3 as    
amended on Form S-2, filed with the Securities and Exchange Commission on June
___, 1998 (the "Registration Statement"), and such other documents as we deemed
necessary.
    

On the basis of the foregoing, it is our opinion that the distribution of the
Rights to the Existing Shareholders should not be a taxable transaction,
although the matter is not free from doubt.

The opinion set forth above is based upon the applicable provisions of the
Internal Revenue Code of 1986, as amended, the Treasury Regulations promulgated
or proposed thereunder, current positions of the Internal Revenue Service (the
"IRS") contained in published revenue rulings, revenue procedures, and
announcements, existing judicial decisions, and other applicable authorities. No
tax rulings have been or will be sought from the IRS with respect to any of the
matters discussed herein. Unlike a ruling from the IRS, opinions of counsel are
not binding on the IRS. Hence, no assurance can be given that the opinion stated
in this letter will not be successfully challenged by the IRS. We express no
opinion concerning any United States federal income tax consequences of the
Rights Offering except as expressly set forth above.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this firm and the summarization
of this opinion under the section titled "Certain Federal Income Tax
Considerations" in the Registration Statement.

Very truly yours,



Haynes and Boone, LLP

Suite 1900

Attn: Jeff Moore

                  Re: Standby Purchase Commitment

Gentlemen:

         EXCO Resources, Inc., a Texas corporation (the "Company"), hereby
confirms its agreement with Ares Management, L.P., on behalf of Ares Leveraged
Investment Fund, L.P. (the "Purchaser") as follows:

   
         1.      Offering of Rights to Purchase Common Stock.  As described in
that certain Prospectus (herein so called) of the Company, dated June __, 1998,
the Company distributed (the "Rights Offering") to all of its recordholders of
Common Stock, par value $0.02 per share (the "Common Stock"), the right (each a
"Right" and collectively, the "Rights") to purchase authorized but unissued
shares of Common Stock at an exercise price of $____ per share (the "Exercise
Price"). The shares of Common Stock which are issuable upon exercise of the
Rights are herein called the "Rights Shares." All unexercised Rights will
expire at the close of business 45 days after the effective date of the Rights
Offering (the "Expiration Date").
    

         One of the components of the Rights Offering is a standby commitment
(the "Standby Commitment") to exercise any Rights which have not been exercised
at or prior to the close of business on the Expiration Date. Subject to the
terms and conditions hereinafter set forth, Purchaser hereby assumes the
Standby Commitment and agrees to exercise any and all Rights which would
otherwise expired unexercised on the Expiration Date (up to a maximum of 2
million Rights) at a price equal to the Exercise Price. The shares of Common
Stock purchased pursuant to the Standby Commitment are hereinafter referred to
as the "Standby Shares."

         2.      Representations and Warranties of the Company.  The Company
represents, warrants and agrees that:

                 (1)      The Company is subject to the informational
         requirements of the Securities Exchange Act of 1934, as amended (the
         "Exchange Act"), and in accordance therewith has timely filed
         documents (the "Exchange Act Documents") with the Securities and
         Exchange Commission (the "Commission") since December 1, 1997.  At the
         time such Exchange Act Documents were filed with the Commission, they
         complied in all material respects with the
<PAGE>   2
         requirements of the Exchange Act and the rules and regulations of the
         Commission thereunder (the "Rules and Regulations"), and did not
         include an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading, and any Exchange Act Documents
         hereafter filed will, when they are filed with the Commission, comply
         in all material respects with the requirements of the Exchange Act and
         the Rules and Regulations, and will not include an untrue statement of
         a material fact or omit to state a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they are made, not misleading.

                 (2)      Since the date of the Company's most recent Exchange
         Act Document, there is no material fact, circumstance or event with
         respect to the Company or any of its subsidiaries that has had or may
         be expected to have a material adverse effect on the business,
         properties, condition (financial or other) or results of operations of
         the Company and its subsidiaries taken as a whole.

                 (3)      The issued and outstanding shares of Common Stock of
         the Company and the shares of Common Stock issuable upon exercise of
         the Rights have been duly authorized.  The issued and outstanding
         shares of Common Stock of the Company are validly issued and
         outstanding, fully paid and non-assessable, with no personal liability
         attaching to the ownership thereof.  There are no issued or
         outstanding shares of Preferred Stock, par value $0.01 per share, of
         the Company.  There is not any preemptive or other right to subscribe
         for or to purchase, or any lien, charge, encumbrance, restriction on
         voting or transfer of, or any other claim of any third party  on, any
         issued and outstanding shares of Common Stock or the Rights Shares,
         pursuant to the Company's corporate charter or by-laws or any
         agreement or other instrument to which the Company is a party or by
         which the Company may be bound. The capitalization of the Company as
         of the date hereof and the anticipated capitalization of the Company
         after the completion of the Rights offering are set forth in the
         Capitalization section of the Prospectus.

                 (4)      The Standby Shares will, when issued and sold to the
         Purchaser as contemplated hereby, be validly authorized, issued and
         outstanding, fully paid and non-assessable with no personal liability
         attaching to the ownership thereof and will conform to the description
         of the Common Stock contained in the Exchange Act Documents.

                 (5)      Each Right is convertible into one share of Common
         Stock.

                 (6)      As of the close of business on the second business
         day preceding the date hereof, there were 508,900 shares of Common
         Stock outstanding; the exercise of all the Rights has been duly
         authorized by the Company.

                 (7)      This Agreement has been duly authorized, executed and
         delivered by the Company, constitutes the valid and binding agreement
         of the Company and is enforceable against the Company in accordance
         with its terms.  No further approval or authorization of the
         shareholders or the Board of Directors of the Company or any other
         entity will be


                                       2
<PAGE>   3
         required for the issuance and sale of Common Stock referred to in
         subparagraph (d) above.  Neither such issuance nor the consummation of
         any other transactions herein contemplated will result in a breach by
         the Company of any terms of, or constitute a default under, any other
         agreement or undertaking of the Company, which breach or default might
         be expected to have a material adverse effect on such Common Stock,
         the Company or the transactions contemplated herein.  Other than as
         contemplated herein, no person has the right to require the Company or
         any subsidiary of the Company to register any capital stock for
         offering and sale under the Securities Act of 1933, as amended (the
         "SECURITIES ACT").

                 (8)      The Company and its subsidiary each have been duly
         incorporated and each is a validly existing corporation in good
         standing under the laws of its jurisdiction of incorporation and is
         duly qualified and in good standing in each jurisdiction in which its
         ownership of property or the conduct of its business requires such
         qualification (except where the failure to so qualify would not have a
         material adverse effect upon the Company and its subsidiary taken as a
         whole).  The Company and its subsidiary each have the corporate power
         and authority and holds all valid permits and other required
         authorizations from governmental authorities necessary to carry on
         business as now conducted and as to be conducted on the Delivery Date
         (as hereinafter defined) except such permits and authorizations that
         are not singly or in the aggregate, material to the Company and its
         subsidiary taken as a whole; neither entity has received any notice
         relating to the revocation or modification of any such permits or
         authorizations that are singly or in the aggregate material to the
         Company and its subsidiary taken as a whole.

                 (9)      Except as described in the Exchange Act Documents,
         there is no action, suit or proceeding pending before any court,
         arbitrator or governmental body, nor, to the knowledge of the Company,
         is any such action threatened, which (i) might affect the consummation
         of the transactions contemplated by this Agreement, (ii) is required
         to be disclosed under the Exchange Act or the Rules and Regulations
         or, in the case of any threatened action, would be required to be so
         disclosed if such action were pending or (iii) would be likely to
         result in any material adverse change in the financial position,
         results of operations or business of the Company and its subsidiaries
         taken as a whole.

         3.      Representations and Warranties of Purchaser.  The Purchaser
represents and warrants that it is purchasing the Standby Shares for its own
account and not with any intention of selling or transferring the Standby
Shares in violation of the Securities Act, subject, nevertheless, to the
understanding that the disposition of Purchaser's property shall at all times
be and remain within Purchaser's control.

         4.      Purchase, Delivery and Payment of Conversion Shares.
Purchaser agrees to purchase from the Company the Standby Shares at a purchase
price equal to the aggregate applicable Exercise Price of the Standby Shares.

                 Delivery of and payment for the Standby Shares shall be made
at the offices of Haynes and Boone, LLP, 901 Main Street, Suite 3100, Dallas,
Texas, at 9:00 a.m., Dallas time, on ______________, 1998, or on such later
date (but not later than three business days after the





                                       3
<PAGE>   4
Expiration Date) as may be specified by written notice from the Purchaser to
the Company given not more than two business days prior to the Expiration Date
(such delivery and payment date being the "Delivery Date").  The date and time
for such delivery and payment are herein sometimes referred to as the Delivery
Date.  On the Delivery Date, the Company shall deliver to the Purchaser
certificates for the Standby Shares against payment of the purchase price
therefor by wire transfer to an account designated by the Company to the
Purchaser at least one business day prior to the Delivery Date.  Such
certificates shall be registered in such name or names and in such number of
shares of Common Stock as the Purchaser shall request in writing not less than
two full business days prior to the Delivery Date.  For purposes of expediting
the checking and packaging of the certificates to be so delivered, the Company
shall make such certificates available for inspection by the Purchaser in
Dallas, Texas, not later than 5:00 p.m., Dallas time, on the business day prior
to the Delivery Date.

         5.      Further Agreements of the Company.  The Company agrees:

                 (1)      To timely file all documents, and any amendments of
         previously filed documents, required to be filed by it pursuant to
         Section 13, 14 or 15(d) of the Exchange Act;

                 (2)      To direct the Transfer Agent to advise you daily of
         the number of Rights exercised for Common Stock on the preceding day;

                 (3)      To take no action the effect of which would be to
         require an adjustment in the exercise price of the shares of Common
         Stock from the present price set above;

         6.      Conditions of the Purchaser's Obligations.  The obligations of
the Purchaser hereunder are subject to the accuracy in all material respects,
when made and on the Delivery Date, of the representations and warranties of
the Company contained herein, to performance by the Company of its obligations
hereunder and to each of the following additional terms and conditions:

                 (1)      The legality and sufficiency of the exercise of the
