                               OFFER TO EXCHANGE
           ALL OUTSTANDING 8 1/4% SENIOR SUBORDINATED NOTES DUE 2011
                        ($300,000,000 PRINCIPAL AMOUNT)
                          ISSUED ON DECEMBER 17, 2002
                                      FOR

                   8 1/4% SENIOR SUBORDINATED NOTES DUE 2011
                        ($300,000,000 PRINCIPAL AMOUNT)
          WHICH HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933

THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON
            , 2003, UNLESS WE EXTEND THE OFFER. WE DO NOT CURRENTLY INTEND TO
EXTEND THE EXCHANGE OFFER.
                             ---------------------

- - We are offering to exchange up to $300 million aggregate principal amount of
  new 8 1/4% Senior Subordinated Notes Due 2011, or exchange notes, which have
  been registered under the Securities Act of 1933, as amended, for an equal
  principal amount of our outstanding 8 1/4% Senior Subordinated Notes Due 2011,
  issued in a private offering on December 17, 2002, or old notes. The old notes
  were issued as additional debt securities under an indenture pursuant to
  which, on November 5, 2001, we issued $275 million of 8 1/4% Senior
  Subordinated Notes Due 2011, which were subsequently exchanged for an equal
  principal amount of notes registered under the Securities Act, or the initial
  exchange notes.

- - We will exchange all old notes that are validly tendered and not validly
  withdrawn prior to the closing of the exchange offer for an equal principal
  amount of exchange notes that have been registered.

- - You may withdraw tenders of old notes at any time prior to the expiration of
  the exchange offer.

- - The terms of the exchange notes are identical in all material respects to the
  old notes, except for transfer restrictions and registration rights that do
  not apply to the exchange notes, and different administrative terms.

- - The exchange notes, together with any old notes not exchanged in the exchange
  offer and the initial exchange notes, will constitute a single class of debt
  securities under the indenture.

- - The exchange of notes will not be a taxable exchange for United States federal
  income tax purposes.

- - We will not receive any proceeds from the exchange offer.

- - No public market exists for the old notes. We do not intend to list the
  exchange notes on any securities exchange and, therefore, no active public
  market is anticipated.
                             ---------------------

     SEE "RISK FACTORS" BEGINNING ON PAGE 13 FOR A DISCUSSION OF FACTORS THAT
YOU SHOULD CONSIDER BEFORE TENDERING YOUR OLD NOTES.
                             ---------------------

     Each broker-dealer that receives exchange notes for its own account
pursuant to the exchange offer must acknowledge that it will deliver a
prospectus in connection with any resale of such exchange notes. The letter of
transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. This prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of exchange notes received in exchange for old notes where such old
notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. We have agreed that, for a period of 180
days after the consummation of the exchange offer, we will make this prospectus
available to any broker-dealer for use in connection with any such resale. See
"Plan of Distribution."

     NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL
OFFENSE.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     Our disclosure and analysis in this prospectus, including information
incorporated by reference, may include forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended, or the
Securities Act, Section 21E of the Securities Exchange Act of 1934, as amended,
or the Exchange Act, and the Private Securities Litigation Reform Act of 1995,
that are subject to risks and uncertainties. Forward-looking statements give our
current expectations and projections relating to the acquisition, which closed
on December 17, 2002, of certain natural gas properties and midstream gathering
and compression assets located in Utah from certain affiliates of El Paso
Corporation, and the financial condition, results of operations, plans,
objectives, future performance and business of Westport Resources Corporation
and its subsidiaries. You can identify these statements by the fact that they do
not relate strictly to historical or current facts. These statements may include
words such as "anticipate," "estimate," "expect," "project," "intend," "plan,"
"believe" and other words and terms of similar meaning in connection with any
discussion of the timing or nature of future operating or financial performance
or other events. All statements other than statements of historical facts
included or incorporated by reference in this prospectus that address
activities, events or developments that we expect, believe or anticipate will or
may occur in the future are forward-looking statements and include, among other
things, statements relating to:

     - amount, nature and timing of capital expenditures;

     - drilling of wells;

     - reserve estimates;

     - timing and amount of future production of oil and natural gas;

     - operating costs and other expenses;

     - cash flow and anticipated liquidity;

     - estimates of proved reserves, exploitation potential or exploration
       prospect size; and

     - marketing of oil and natural gas.

     These forward-looking statements are based on our expectations and beliefs
concerning future events affecting us and are subject to uncertainties and
factors relating to our operations and business environment, all of which are
difficult to predict and many of which are beyond our control. Although we
believe that the expectations reflected in our forward-looking statements are
reasonable, we do not know whether our expectations will prove correct. Any or
all of our forward-looking statements in or incorporated into this prospectus
may turn out to be wrong. They can be affected by inaccurate assumptions we
might make or by known or unknown risks and uncertainties. Many factors
mentioned or incorporated by reference in this prospectus will be important in
determining future results. Actual future results may vary materially. Because
of these factors, we caution that investors should not place undue reliance on
any of our forward-looking statements. Further, any forward-looking statement
speaks only as of the date on which it is made, and except as required by law we
undertake no obligation to update any forward-looking statement to reflect
events or circumstances after the date on which it is made or to reflect the
occurrence of anticipated or unanticipated events or circumstances.

                         WESTPORT RESOURCES CORPORATION

     We are an independent energy company engaged in oil and natural gas
exploitation, acquisition and exploration activities primarily in the United
States. Our reserves and operations are concentrated in the following divisions:
Western, which includes the Acquired Properties in the Uinta Basin; Northern,
which primarily includes properties in North Dakota and Wyoming; Southern, which
primarily includes properties in Oklahoma, Texas and Louisiana; and Gulf of
Mexico, which includes our offshore properties. We focus on maintaining a
balanced portfolio of lower-risk, long-life onshore reserves and higher-margin
offshore reserves to provide a diversified cash flow foundation for our
exploitation, acquisition and exploration activities.

     On December 17, 2002, effective as of June 1, 2002, we acquired producing
properties, undeveloped leaseholds, gathering and compression facilities and
other related assets in the Greater Natural Buttes area of Uintah County, Utah
from El Paso for approximately $510 million, including purchase price
adjustments, pursuant to the Purchase and Sale Agreement, dated November 6,
2002, as amended. We used the net proceeds from our December 16, 2002 shelf
offering and December 17, 2002 debt offering to fund the purchase price. See
"-- Recent Developments."

     The Acquisition establishes a new core area and has the following
attributes:

     - increases our proved reserves by approximately 57%, or 603 Bcfe,
       replacing approximately 465% of our estimated 2002 production and giving
       us nearly 1 Tcfe of proved reserves in the Rocky Mountains;

     - raises current production in excess of 20%, to approximately 417 Mmcfe/d,
       placing us among the top 20 largest domestic independent exploration and
       production companies based on third quarter 2002 daily production;

                                        1


     - adds long-life, operated gas properties with a reserves to production
       ratio of 21 years, extending our overall reserve life index from
       approximately seven years to approximately 11 years and increasing the
       gas portion of both our proved reserves and production to 68%;

     - contains upside potential with over 600 proved undeveloped locations and
       approximately 900 additional drilling opportunities;

     - provides exploration opportunities on over 240,000 net acres of
       leasehold, including targets outside the producing areas and deeper
       formations within the producing areas; and

     - allows us to control the gathering and marketing of our natural gas from
       the Acquired Properties and affords us access to interstate pipelines
       flowing east, such as Colorado Interstate Gas, and west, such as Kern
       River.

     Since entering into the Purchase and Sale Agreement, we have secured firm
transportation averaging at least 107 Mmbtu/d for 2003 and increasing annually
over the next three years thereafter, hedged 98% of expected 2003
Acquisition-related production at floor and ceiling prices averaging $3.81 to
$3.99 per Mmbtu, respectively, and 63% of estimated 2004 Acquisition-related
production at floor and ceiling prices of $3.76 to $3.87 per Mmbtu,
respectively. Additionally, we have hedged basis differentials for approximately
65% of anticipated 2003 Acquisition-related production and 50% of anticipated
2004 Acquisition-related production.

     Over the last several years, acquisitions and subsequent exploitation
focused in core project areas have fueled growth in our reserves, production and
cash flow. From year-end 1997 to September 30, 2002, we increased proved
reserves from 197 Bcfe to 1,662 Bcfe, a compounded annual growth rate of
approximately 53%. Over the same period we increased average daily production
from 66 Mmcfe/d to 417 Mmcfe/d, a compounded annual growth rate of approximately
45%. This growth has been complemented by consistent reductions in our per unit
cost structure over the same period from $1.32 per Mcfe to $1.05 per Mcfe of our
net production for lease operating expenses, transportation costs, production
taxes, and general and administrative costs. For the 12 months ended September
30, 2002, we generated net revenues and EBITDAX of $437 million and $296
million, respectively.

     We believe that our sizable exploration inventory and our exploitation and
acquisition expertise, together with our operating experience and efficient cost
structure, provide us with the ability to generate substantial current cash flow
and position us for future growth. We operate approximately 79% of the net
present value of our reserves, allowing us to better manage expenses, capital
allocation and the decision-making processes related to all aspects of
exploitation and exploration activities. We have a capital budget of
approximately $170 million for 2002, which does not include acquisitions. Nearly
65% of the 2002 budget is allocated to exploitation, which includes lower-risk
drilling and continued expansion of our secondary recovery projects. We expect
that our total 2003 capital budget, excluding acquisitions, will be $230
million, 75% of which has been allocated to exploitation. We have approximately
2,300 identified exploitation opportunities and anticipate drilling 300 to 350
of these locations during 2003.

     As of September 30, 2002, our estimated proved reserves of 1,662 Bcfe had a
pre-tax net present value, discounted at 10%, of approximately $2.3 billion
based on period-end NYMEX prices of $30.45 per barrel of oil and $4.14 per Mmbtu
of natural gas. Approximately 66% of our reserves was classified as proved
developed as of September 30, 2002. The following table sets forth a summary of
third quarter 2002 production and

OUR STRATEGY

     Our strategy is to grow our reserve base and production, maintain our
diversified risk profile and expand our investment opportunities primarily by
actively executing on lower-risk exploitation projects and acquisitions.
Although our emphasis is on exploitation and acquisition activities, we will
continue drilling potentially higher-impact exploration prospects, thereby
balancing risks while maintaining significant potential for growth. To
accomplish this strategy, we will:

     - enhance our exploitation activity by allocating 75% to 85% of our capital
       budget to exploitation to increase production and enhance our reserve
       base;

     - continue our acquisition activity to achieve greater immediate cash flow
       and expand our exploitation inventory;

     - continue to generate and drill an extensive prospect inventory by
       applying current technology and leveraging our significant operational
       capabilities and acreage inventory; and

     - maintain financial flexibility and a conservative capital structure
       through prudent financial and hedging activities.

     We intend to implement our strategy as follows:

     Expand our Exploitation Program.  We plan to drill 300 to 350 exploitation
wells in 2003. For the nine months ended September 30, 2002, we drilled 153
development wells onshore and five development wells offshore in the Gulf of
Mexico, 155 of which were successful, resulting in a 98% success rate. In 2001,
we drilled 242 development wells onshore and nine development wells offshore in
the Gulf of Mexico, resulting in a 96% success rate. We have identified
approximately 2,300 prospective exploitation projects both onshore and offshore,
including more than 1,500 drilling opportunities that we added with the
Acquisition.

     Actively Pursue and Capitalize on Acquisitions.  Due to a trend toward
industry consolidation and asset rationalization, we believe that we will
continue to have opportunities to acquire oil and natural gas properties at
attractive rates of return. We have an experienced management team focused on
executing our disciplined approach to identify and capture these opportunities.

                                        3


     Through a series of acquisitions from 1995 through 2000, we substantially
increased our reserve base by investing approximately $454 million in acquiring
oil and natural gas properties at an average unit acquisition cost of $1.10 per
Mcfe based on our December 31, 2001 reserve report. Through December 31, 2001,
we invested an additional $199 million to exploit these acquired properties and
added proved reserves of 161 Bcfe. The subsequent reserve additions resulting
from these exploitation activities replaced approximately 87% of production from
the acquired properties during this same period. These acquisitions generated
revenues less direct expenses through December 31, 2001 of approximately $482
million, or 74% of the total capital invested.

     In a similar manner, we intend to capitalize on our two most recent
acquisitions. The properties that we acquired from El Paso include approximately
205,000 net developed acres and approximately 35,000 net undeveloped acres. We
have identified approximately 1,500 exploitation opportunities and several
deeper exploration opportunities. We expect to drill 80 to 90 wells in 2003 with
plans to accelerate the drilling program in 2004 and beyond. We entered into
additional hedging arrangements to manage our exposure to commodity price
volatility and basis differentials. Since closing the Southeast Texas
Acquisition, we have drilled two field extension wells and one exploration well,
all of which have been successful.

     Capitalize on Exploration Opportunities.  We continue to focus on enhancing
reserve and production growth in our core areas by emphasizing and applying the
latest geological, geophysical and drilling technologies. We seek exploration
opportunities with characteristics similar to producing properties in our core
areas in order to leverage our technical and operational expertise.

     Onshore, we hold interests in approximately 1.3 million gross
(approximately 0.6 million net) undeveloped acres, approximately 90% of which
are located in the principal natural gas basins of the Rocky Mountains. Over the
next 12 to 24 months, we plan to drill seven to 10 exploration wells in the
Rocky Mountains. In connection with the Southeast Texas Acquisition, we have
identified 15 3-D defined prospects that we plan to drill over the next 12 to 24
months. We are also currently shooting 180 square miles of additional 3-D
seismic data in this area with industry partners.

     In the Gulf of Mexico, we hold interests in approximately 0.3 million gross
(approximately 0.2 million net) undeveloped acres and have an exploration
inventory of 16 prospects located on 20 blocks with additional exploration
opportunities in several of our 70 developed blocks. We have under license 3-D
seismic data covering over 18,000 square miles (2,300 blocks) and 2-D seismic
data covering over 150,000 linear miles in this area. In order to control
activity, our strategy typically includes retaining large working interests in
our internally-generated prospects. Prior to drilling, we typically sell down
our working interest or trade a portion of these prospects for interests in
prospects developed by others. This strategy allows us to achieve multiple
prospect exposure while diversifying our investment risk.

     Maintain Financial Flexibility and a Conservative Capital Structure.  We
plan to maintain financial flexibility and a conservative capital structure,
which we believe is integral to the successful execution of our exploitation,
acquisition and exploration strategy. Historically, we have maintained a
conservative capital structure. As a result of the Acquisition, we substantially
increased our leverage. We intend to reduce our leverage through a combination
of the following:

     - application of excess cash flow to debt repayment;

     - property dispositions; and

     - issuance of equity.

RECENT DEVELOPMENTS

     Southeast Texas Acquisition.  On September 30, 2002, we acquired oil and
gas properties located in southeast Texas, also referred to as the Southeast
Texas Acquisition, for a total cash purchase price of approximately $120
million, subject to certain downward purchase price adjustments. We estimate the
total proved reserves in the acquired properties to be approximately 76 Bcfe, of
which 82% is natural gas. We operate substantially all of the properties. The
purchase also includes 10,000 net undeveloped acres and an

                                        4


interest in 120 square miles of 3-D seismic data. We are currently shooting an
additional 180 square miles of 3-D seismic data. The properties are located
primarily in the Gulf Coast region of southeast Texas. As of September 30, 2002
the acquired properties were producing approximately 28 Mmcfe/d, net to the
acquired interests.

     The Private Equity Offering.  On November 19, 2002, we completed a private
equity offering of 3.125 million shares of our common stock to Spindrift
Partners, L.P., Spindrift Investors (Bermuda) L.P., Global Natural Resources III
and Global Natural Resources III L.P. at a net price to us of $16.00 per share
for aggregate proceeds of $50 million. The purchasers may not sell this common
stock until 90 days after the closing of the private equity offering and may be
prohibited from selling this common stock at our option for up to 187 days in
the event we pursue a public equity offering during the next two years. The
terms of the sale were negotiated on November 11, 2002 and the net price
represents a 9% discount from the closing price of our common stock on the New
York Stock Exchange as of that date.

     In connection with the private equity offering, we agreed to file a shelf
registration statement registering the resale by the selling stockholders from
time to time of the common stock we issued in the private equity offering. We
also agreed to use our reasonable best efforts to cause the registration
statement to become effective within 90 days of the closing of the private
equity offering. In addition, we agreed, subject to certain rights of
suspension, to keep such registration statement effective until the earlier of
(1) the date on which all of the shares have been (a) sold under the
registration statement or (b) distributed pursuant to Rule 144(k) under the
Securities Act or (2) two years after the date of the stock purchase agreement.
On December 31, 2002, we filed the shelf registration statement registering the
resale by the selling stockholders from time to time of our common stock issued
in the private equity offering, which registration statement the SEC declared
effective on January 7, 2003.

     Shelf Offering.  On December 16, 2002, we closed a public offering, or the
shelf offering, of 11.5 million shares of common stock at a price of $19.90 per
share, which includes 1.5 million shares covered by an over-allotment option we
granted to, and which was exercised by, the underwriters. We received net
proceeds of approximately $216 million from the sale of our common stock, which
we used to finance, in part, the Acquisition.

     Replacement Credit Facility.  On December 17, 2002, we entered into a
credit facility with JPMorgan Chase Bank and Credit Suisse First Boston
Corporation, referred to as the Replacement Credit Facility, to replace our
previous revolving credit facility. The Replacement Credit Facility provides for
a maximum committed amount of $600 million and an initial borrowing base of
approximately $470 million. The facility matures on December 16, 2006 and
contains covenants and default provisions customary for similar credit
facilities. We made borrowings under the Replacement Credit Facility to
refinance all outstanding indebtedness under our previous revolving credit
facility and to pay general corporate expenses.

     As of January 15, 2003, we had borrowings and letters of credit issued of
approximately $111 million outstanding under the Replacement Credit Facility,
with a weighted average interest rate of 3.3% and available unused borrowing
capacity of approximately $359 million.

     8 1/4% Senior Subordinated Notes Due 2011. On December 17, 2002, we issued
$300 million in additional principal amount of our 8 1/4% Senior Subordinated
Notes Due 2011, or the old notes, pursuant to Rule 144A under the Securities Act
at a price of 103% of the principal amount, with accrued interest from November
1, 2002, or the debt offering. The old notes are additional debt securities
under the Indenture pursuant to which, on November 5, 2001, we issued $275
million of our 8 1/4% Senior Subordinated Notes Due 2011. On March 14, 2002, all
of the 2001 notes were exchanged in an exchange offer for an equal principal
amount of the initial exchange notes. We used the proceeds from the sale of the
old notes to finance, in part, the Acquisition. We have agreed to file this
exchange offer registration statement or, under certain circumstances, a shelf
registration statement pursuant to a registration rights agreement relating to
the old notes. In the event we fail to comply with some of our obligations under
the registration rights agreement relating to the old notes, we will pay
additional interest on the old notes. We are currently offering to exchange up
to $300 million aggregate principal amount of new 8 1/4% Senior Subordinated
Notes Due 2011, or exchange notes, that have been registered under the
Securities Act for an equal principal amount of old notes.
                                        5


     Throughout this prospectus, we refer to the November 19, 2002 private
equity offering, the December 16, 2002 shelf offering and the December 17, 2002
debt offering as the Offerings, and together with the Acquisition and the
initial borrowings under our Replacement Credit Facility, as the Transactions.

FAILURE TO EXCHANGE YOUR OLD NOTES

     Any old notes that you do not tender or that we do not accept will,
following the exchange offer, continue to be restricted securities. Therefore,
you may only transfer or resell them in a transaction registered under or exempt
from the Securities Act and applicable state securities laws. We will issue the
exchange notes in exchange for the old notes in this exchange offer only
following the satisfaction of the procedures and conditions discussed under the
caption "The Exchange Offer."

     Because we anticipate that most holders of the old notes will elect to
exchange their old notes, we expect that the liquidity of the market, if any,
for any old notes remaining after the completion of the exchange offer will be
substantially limited. Any old notes tendered and exchanged in the exchange
offer will reduce the aggregate principal amount outstanding of the old notes.

                               THE EXCHANGE OFFER

     On December 17, 2002, we completed a private offering of $300 million of
our unregistered 8 1/4% Senior Subordinated Notes Due 2011, or the old notes.
The old notes were offered as additional debt securities under the Indenture
pursuant to which, on November 5, 2001, we issued $275 million of our 8 1/4%
Senior Subordinated Notes Due 2011. On March 14, 2002, all of the notes issued
in the 2001 offering were exchanged in an exchange offer for an equal principal
amount of the notes registered under the Securities Act, or the initial exchange
notes. In this exchange offer, we are offering to exchange, for your old notes,
exchange notes that are identical in all material respects to the old notes,
except for transfer restrictions and registration rights that do not apply to
the exchange notes, and different administrative terms.

Consequences of Failure to
Exchange Your Old Notes.......   Old notes not exchanged in the exchange offer
                                 will continue to be subject to the restrictions
                                 on transfer that are described in the legend on

                                 sell your old notes only if they are registered
                                 under, or offered or sold under an exemption
                                 from, the Securities Act and applicable state
                                 securities laws. We do not currently intend to

                                 accepted in the exchange offer, it may become
                                 more difficult for you to sell or transfer your
                                 old notes.

                                 interest to the date of redemption. The term
                                 "Applicable Premium" is defined under
                                 "Description of Exchange Notes -- Certain
                                 Definitions."

                                 On or after November 1, 2006, we are entitled
                                 to redeem some or all of the notes at the fixed
                                 redemption prices listed under "Description of
                                 Exchange Notes -- Optional Redemption," plus
                                 accrued and unpaid interest to the date of
                                 redemption.

Guaranties....................   The payment of the principal, interest and
                                 premium on the exchange notes will be fully and
                                 unconditionally guaranteed on a senior
                                 subordinated basis by some of our existing and
                                 future restricted subsidiaries. See
                                 "Description of Exchange Notes -- Guaranties."

                                 The subsidiary guaranties will rank equal in
                                 right of payment with the guarantor
                                 subsidiaries' guaranties of our initial

                                 subsidiaries.

Restrictive Covenants.........   The Indenture governing the notes limits what
                                 we and our restricted subsidiaries do. The
                                 provisions of the Indenture limit our and such
                                 subsidiaries' ability, among other things, to:

                                 - incur additional indebtedness;

                                 - pay dividends on our capital stock or redeem,
                                   repurchase or retire our capital stock or
                                   subordinated indebtedness;

                                 - make investments;

                                 - incur liens;

                                 - create any consensual limitation on the
                                   ability of our restricted subsidiaries to pay
                                   dividends, make loans or transfer property to
                                   us;

                                 - engage in transactions with our affiliates;

                                 - sell assets, including capital stock of our
                                   subsidiaries; and

                                 - consolidate, merge or transfer assets.

                                 During any period that the notes have
                                 investment grade ratings from both Moody's
                                 Investors Service, Inc. and Standard and Poor's
                                 Ratings Group and no default has occurred and
                                 is continuing, the foregoing covenants will
                                 cease to be in effect with the exception of
                                 covenants that contain limitations on liens and
                                 on, among other things, certain consolidations,
                                 mergers and transfers of assets.

                                 These covenants are subject to important
                                 exceptions and qualifications described under
                                 "Description of Exchange Notes -- Certain
                                 Covenants."

Change of Control.............   If we experience a Change of Control, subject
                                 to certain conditions, we must give holders of
                                 the notes the opportunity to sell to us their
                                 notes at 101% of the principal amount, plus
                                 accrued and unpaid interest. The term "Change
                                 of Control" is defined under "Description of
                                 Exchange Notes -- Change of Control."

Absence of a Public Market for
the Exchange Notes............   The exchange notes will be a new issue of debt
                                 securities of the same class as the initial
                                 exchange notes and will generally be freely
                                 transferable. Notwithstanding the foregoing, we
                                 cannot assure you as to the development of an
                                 active market for the exchange notes or their
                                 liquidity. We do not intend to apply for
                                 listing of the exchange notes on any securities
                                 exchange or any automated dealer quotation
                                 system.

     YOU SHOULD REFER TO THE SECTION ENTITLED "RISK FACTORS" FOR AN EXPLANATION
OF CERTAIN RISKS ASSOCIATED WITH THE EXCHANGE NOTES.

                                        12


                                  RISK FACTORS

     You should carefully consider the following factors, as well as the other
information contained or incorporated by reference in this prospectus, before
deciding to exchange your old notes for the exchange notes. An investment in the
notes represents a high degree of risk. There are a number of factors, including
those specified below, which may adversely affect our ability to make payments
on the notes. You could therefore lose a substantial portion or all of your
investment in the notes. Consequently, an investment in the notes should only be
considered by persons who can assume such risk. The risk factors described below
are not necessarily exhaustive and you are encouraged to perform your own
investigation with respect to the notes and us. Each of the risks described in
this section with respect to the exchange notes are generally applicable to the
old notes. Before making your investment decision, you should also read the
other information presented or incorporated by reference in this prospectus,
including our financial statements and the related notes.

RISKS RELATED TO OUR BUSINESS

  OIL AND NATURAL GAS PRICES FLUCTUATE WIDELY, AND LOW PRICES COULD HARM OUR
  BUSINESS.

     Our results of operations are highly dependent upon the prices of oil and
natural gas. Historically, oil and natural gas prices have been volatile and are
likely to continue to be volatile in the future. For example, our average
realized sales prices for oil and natural gas for the nine months ended
September 30, 2001 were $24.12/bbl and $4.31/Mcf, respectively, with production
totaling 56 Bcfe and combined oil and natural gas sales of $234 million during
this period, without giving effect to the Transactions. Our average realized
sales prices for oil and natural gas for the nine months ended September 30,
2002, were $22.92/bbl and $2.68/Mcf, with production increasing to 95 Bcfe and
combined oil and natural gas sales increasing to $295 million during this
period, without giving effect to the Transactions. The prices upon which we
calculated our present value of estimated future net revenues as of September
30, 2002 may not be indicative of the prices that we can actually receive for
our production. Such prices may be substantially less. The prices received for
oil and natural gas production depend upon numerous factors including, among
others:

     - consumer demand;

     - governmental regulations and taxes;

     - the price and availability of alternative fuels;

     - geopolitical developments;

     - commodity processing, gathering and transportation availability;

     - the level of foreign imports of oil and natural gas; and

     - the overall economic environment.

     All of these factors are beyond our control. Any significant decrease in
prices for oil and natural gas could have a material adverse effect on our
financial condition, results of operations and quantities of reserves that are
commercially recoverable. If the oil and natural gas industry experiences
significant future price decreases or other adverse market conditions, we may
not be able to generate enough cash flow from operations to meet our obligations
and make planned capital expenditures.

  WE WILL REQUIRE SUBSTANTIAL CAPITAL TO FUND OUR OPERATIONS.

     We expect for the foreseeable future to make substantial capital
expenditures for the acquisition, exploration and development of oil and natural
gas reserves. Historically, we have paid for these expenditures primarily with
cash from operating activities and with proceeds from debt and equity
financings. If revenues decrease as a result of lower oil and natural gas prices
or for any other reason, we may not have the funds available to replace our
reserves or to maintain production at current levels, which would result in a
decrease in production over time.

                                        13


  OUR FORMER INDEPENDENT PUBLIC ACCOUNTANT, ARTHUR ANDERSEN LLP, HAS BEEN FOUND
  GUILTY OF A FEDERAL OBSTRUCTION OF JUSTICE CHARGE, AND YOU MAY BE UNABLE TO
  EXERCISE EFFECTIVE REMEDIES AGAINST IT IN ANY LEGAL ACTION.

     Our former independent public accountant, Arthur Andersen LLP, provided us
with auditing services for prior fiscal periods through December 31, 2001,
including issuing an audit report to our audited consolidated financial
statements incorporated by reference in this prospectus. On June 15, 2002, a
jury in Houston, Texas found Arthur Andersen LLP guilty of a Federal obstruction
of justice charge arising from the Federal Government's investigation of Enron
Corp. On August 31, 2002, Arthur Andersen LLP ceased practicing before the SEC.

     We are unable to obtain Arthur Andersen LLP's consent to incorporate by
reference its report included in our Annual Report on Form 10-K for the year
ended December 31, 2001. Under these circumstances, Rule 437a under the
Securities Act permits us to dispense with the requirement to file Arthur
Andersen LLP's consent. As a result, you may not have an effective remedy
against Arthur Andersen LLP in connection with a material misstatement or
omission with respect to our audited consolidated financial statements that are
incorporated by reference in this prospectus or any other filing we may make
with the SEC, including, with respect to any offering registered under the
Securities Act, any claim under Section 11 of the Securities Act. In addition,
even if you were able to assert such a claim, as a result of its conviction and
other lawsuits, Arthur Andersen LLP may fail or otherwise have insufficient
assets to satisfy claims made by investors or by us that might arise under
Federal securities laws or otherwise relating to any alleged material
misstatement or omission with respect to our audited consolidated financial
statements.

     In addition, in connection with any future capital markets transaction in
which we are required to include financial statements that were audited by
Arthur Andersen LLP, as a result of the foregoing, investors may elect not to
participate in any such offering or, in the alternate, may require us to obtain
a new audit with respect to previously audited financial statements.
Consequently, our financing costs may increase or we may miss attractive capital
market opportunities.

  INDIAN TRIBES HAVE PREVIOUSLY CHALLENGED THE VALIDITY OF SOME OF THE PROPERTY
  INTERESTS COVERED BY OIL AND NATURAL GAS LEASES IN THE AREA IN WHICH THE
  ACQUIRED PROPERTIES ARE LOCATED.

     Substantially all of the oil and natural gas leases we acquired in the
Acquisition cover interests located within the Uintah and Ouray Indian
Reservation, in an area originally known as the Umcompahgre Reservation. These
leases were granted by the State of Utah, the United States (through the Bureau
of Land Management) or holders of patents from the United States. The Ute Indian
Tribe has previously asserted various claims against the State of Utah and the
United States regarding the existence, diminishment and/or abrogation of the
Reservation's boundaries and the extent of tribal jurisdiction over these lands.
These lawsuits raised questions as to whether the Ute Tribe could invalidate
through litigation fee patents issued by the United States, the State of Utah's
ownership of such lands or the United States' ownership of minerals subject to
the acquired leases. We believe these issues were conclusively settled as a
result of the Ute Indian Tribe litigation and have no reason to expect that
similar claims will be or could be asserted in the future. We cannot be certain,
however, that additional claims will not be asserted or, if asserted, that such
claims would not be successful. If claims of this nature were successfully
asserted we might not be able to continue to produce hydrocarbons from or
develop and exploit these assets, which could adversely affect our business and
profitability.

  THE GEOGRAPHIC CONCENTRATION OF THE ACQUIRED PROPERTIES IN UTAH SUBJECTS US TO
  INCREASED RISK OF REDUCTION IN REVENUES OR CURTAILMENT OF PRODUCTION FROM
  CERTAIN NEGATIVE CONDITIONS.

     All of the Acquired Properties are located in Uintah County, Utah.
Conditions such as severe weather, delays or decreases in production, the
availability of equipment, facilities or services or the availability of
capacity to transport production could subject us to increased risk of loss of
revenues and have a greater impact on our results of operations since most or
all of the Acquired Properties could be affected by the same event.

                                        14


  WE MAY NOT REALIZE THE ANTICIPATED BENEFITS FROM THE ACQUISITION.

     Our estimates regarding the expenses and liabilities or the increase in our
reserves and production resulting from the Acquisition may prove to be incorrect
or we may not be successful in integrating the Acquired Properties into our
existing business, all of which could have a material adverse effect on our
financial condition and results of operations.

  WE MAY NOT BE ABLE TO CONSUMMATE FUTURE ACQUISITIONS OR SUCCESSFULLY INTEGRATE
  ACQUISITIONS INTO OUR BUSINESS.

     Our business strategy includes growing our reserve base through
acquisitions. We may not continue to be successful in identifying or
consummating future acquisitions or integrating acquired businesses successfully
into our existing business, or in anticipating the expenses or liabilities we
will incur in doing so. Such failures may have a material adverse effect on
future growth or results of operations.

     We are continually investigating opportunities for acquisitions. In
connection with future acquisitions, the process of integrating acquired
operations into our existing operations may result in unforeseen operating
difficulties and may require significant management attention and financial
resources that would otherwise be available for the ongoing development or
expansion of existing operations. Our ability to make future acquisitions may be
constrained by our ability to obtain additional financing.

     Acquisitions may involve a number of special risks, including:

     - unexpected losses of key employees, customers and suppliers of the
       acquired business;

     - conforming the financial, technological and management standards,
       processes, procedures and controls of the acquired business with those of
       our existing operations; and

     - increasing the scope, geographic diversity and complexity of our
       operations.

     Possible future acquisitions could result in our incurring additional debt,
contingent liabilities and amortization expenses related to intangible assets,
all of which could have a material adverse effect on our financial condition and
operating results.

  REPERCUSSIONS FROM TERRORIST ACTIVITIES OR ARMED CONFLICT COULD HARM OUR
  BUSINESS.

     Terrorist activities, anti-terrorist efforts and other armed conflict
involving the United States or its interests abroad may adversely affect the
United States and global economies and could prevent us from meeting our
financial and other obligations. If events of this nature occur and persist, the
attendant political instability and societal disruption could reduce overall
demand for oil and natural gas, potentially putting downward pressure on
prevailing oil and natural gas prices and causing a reduction in our revenues.
Natural gas and oil production facilities, transportation systems and storage
facilities could be direct targets of terrorist attacks, and our operations
could be adversely impacted if infrastructure integral to our operations is
destroyed or damaged by such an attack. Costs for insurance and other security
may increase as a result of these threats, and some insurance coverage may
become more difficult to obtain if available at all.

  OUR COMMODITY PRICE AND BASIS DIFFERENTIAL RISK MANAGEMENT ARRANGEMENTS MAY
  LIMIT OUR POTENTIAL GAINS.

     Commodity prices and basis differentials significantly affect our financial
condition, results of operations, cash flows and ability to borrow funds. Oil
and natural gas prices, as well as basis differentials, are affected by several
factors that we cannot control. We attempt to manage our exposure to oil and
natural gas price volatility by entering into commodity price risk management
arrangements for a portion of our expected production. In addition, we attempt
to manage our exposure to basis differentials between delivery points by
entering into basis swaps. In connection with the Acquisition, we intend to
continue entering into hedging arrangements relating to the production from the
Acquired Properties to help us manage our exposure. While intended to reduce the
effects of volatile oil and natural gas prices and basis differentials,
commodity price and basis differential risk management transactions may limit
our potential gains if oil and natural gas prices were
                                        15


to rise substantially, or basis differentials were to fall substantially, versus
the price or basis differential established by the arrangements. These
transactions also expose us to credit risk of non-performance by the
counterparties to the transaction. In addition, our commodity price and basis
differential risk management transactions may limit our ability to borrow under
our Replacement Credit Facility and may expose us to the risk of financial loss
in certain circumstances, including instances in which:

     - our production is less than expected;

     - there is a widening of price differentials between delivery points for
       our production and the delivery point assumed in non-basis hedge
       arrangements;

     - basis differentials tighten substantially from the prices established by
       these arrangements; or

     - the counterparties to our contracts fail to perform under terms of the
       contracts.

  EXPLORATION IS A HIGH-RISK ACTIVITY. THE SEISMIC DATA AND OTHER ADVANCED
  TECHNOLOGIES WE USE ARE EXPENSIVE AND CANNOT ELIMINATE EXPLORATION RISKS.

     Our oil and natural gas operations are subject to the economic risks
typically associated with drilling exploratory wells. In conducting exploration
activities, we may drill unsuccessful wells and experience losses and, if oil
and natural gas are discovered, there is no assurance that such oil and natural
gas can be economically produced or satisfactorily marketed. There can be no
assurance that new wells we drill will be productive or that we will recover all
or any portion of our investment. The presence of unanticipated pressure or
irregularities in formations, miscalculations or accidents may cause our
exploration activities to be unsuccessful, resulting in a total loss of our
investment in such activities. The cost of drilling, completing and operating
wells is often uncertain. Our drilling operations may be curtailed, delayed or
canceled as a result of numerous factors, many of which may be beyond our
control, including unexpected drilling conditions, title problems, weather
conditions, compliance with environmental and other governmental requirements
and shortages or delays in the delivery of equipment and services.

     We rely to a significant extent on seismic data and other advanced
technologies in conducting our exploration activities. Even when used and
properly interpreted, seismic data and visualization techniques only assist
geoscientists in identifying subsurface structures and hydrocarbon indicators.
Such data are not conclusive in determining if hydrocarbons are present or
economically producible. The use of seismic data and other technologies also
requires greater pre-drilling expenditures than traditional drilling strategies.
We could incur losses as a result of these expenditures.

  FAILURE TO REPLACE RESERVES MAY NEGATIVELY AFFECT OUR BUSINESS.

     Our future success depends upon our ability to find, develop or acquire
additional oil and natural gas reserves that are economically recoverable. Our
proved reserves generally decline when reserves are produced, unless we conduct
successful exploration or development activities or acquire properties
containing proved reserves, or both. We may not be able to find, develop or
acquire additional reserves on an economical basis. Furthermore, while our
revenues may increase if oil and natural gas prices increase significantly, our
finding costs for additional reserves could also increase.

  RESERVE ESTIMATES ARE INHERENTLY UNCERTAIN. ANY MATERIAL INACCURACIES IN OUR
  RESERVE ESTIMATES OR ASSUMPTIONS UNDERLYING OUR RESERVE ESTIMATES, SUCH AS THE
  DISCOUNT RATE USED, COULD CAUSE THE QUANTITIES AND NET PRESENT VALUE OF OUR
  RESERVES TO BE OVERSTATED.

     There are numerous uncertainties inherent in estimating quantities of
proved reserves, including many factors beyond our control, that could cause the
quantities and net present value of our reserves to be overstated. The reserve
information set forth in, or incorporated by reference into, this prospectus is
based on estimates that we prepared. Estimates prepared by others might differ
materially from our estimates. Reserve engineering is not an exact science.
Estimates of economically recoverable oil and natural gas reserves and of

                                        16


future net cash flows necessarily depend upon a number of variable factors and
assumptions, any of which may cause these estimates to vary considerably from
actual results, such as:

     - historical production from the area compared with production from other
       producing areas;

     - assumed effects of regulation by governmental agencies;

     - assumptions concerning future oil and natural gas prices;

     - assumptions regarding future operating costs;

     - estimates of future severance and excise taxes;

     - assumptions regarding capital expenditures; and

     - estimates regarding workover and remedial costs.

     Estimates of reserves based on risk of recovery and estimates of expected
future net cash flows prepared or audited by different engineers, or by the same
engineers at different times, may vary substantially. Actual production,
revenues and expenditures with respect to our reserves will likely vary from
estimates, and the variance may be material. The net present values referred to
in this prospectus should not be construed as the current market value of the
estimated oil and natural gas reserves attributable to our properties. In
accordance with requirements of the SEC, the estimated discounted net cash flows
from proved reserves are generally based on prices and costs as of the date of
the estimate, whereas actual future prices and costs may be materially higher or
lower.

  COMPETITION IN OUR INDUSTRY IS INTENSE, AND MANY OF OUR COMPETITORS HAVE
  GREATER FINANCIAL, TECHNOLOGICAL AND OTHER RESOURCES THAN WE HAVE.

     We operate in the highly competitive areas of oil and natural gas
exploitation, exploration and acquisition. The oil and natural gas industry is
characterized by rapid and significant technological advancements and
introductions of new products and services using new technologies. We face
intense competition from major and independent oil and natural gas companies in
each of the following areas:

     - seeking to acquire desirable producing properties or new leases for
       future exploration;

     - marketing our oil and natural gas production;

     - integrating new technologies; and

     - acquiring the personnel, equipment and expertise necessary to develop and
       operate our properties.

     Many other companies have financial, technological and other resources
substantially greater than our own. These companies may be able to pay more for
exploratory prospects and productive oil and natural gas properties and may be
able to define, evaluate, bid for and purchase a greater number of properties
and prospects than our financial or human resources permit. Further, many of our
competitors may enjoy technological advantages over us and may be able to
implement new technologies more rapidly than we can. Our ability to explore for
oil and natural gas and to acquire additional properties in the future will
depend upon our ability to successfully conduct operations, implement advanced
technologies, evaluate and select suitable properties and consummate
transactions in this highly competitive environment.

  WE ARE SUBJECT TO COMPLEX LAWS AND REGULATIONS, INCLUDING ENVIRONMENTAL AND
  SAFETY REGULATIONS, THAT CAN ADVERSELY AFFECT THE COST, MANNER OR FEASIBILITY
  OF DOING BUSINESS.

     Our operations and facilities are subject to certain Federal, state, tribal
and local laws and regulations relating to the exploration for, and the
development, production and transportation of, oil and natural gas, as well as
environmental and safety matters. Although we believe that we are in substantial
compliance with all applicable laws and regulations, we cannot be certain that
existing laws or regulations, as currently interpreted or reinterpreted in the
future, or future laws or regulations will not harm our business, results of
operations and

                                        17


financial condition. We may be required to make large and unanticipated capital
expenditures to comply with environmental and other governmental regulations,
such as:

     - land use restrictions;

     - drilling bonds and other financial responsibility requirements;

     - spacing of wells;

     - unitization and pooling of properties;

     - habitat and endangered species protection, reclamation and remediation,
       and other environmental protection;

     - safety precautions;

     - operational reporting; and

     - taxation.

     Under these laws and regulations, we could be liable for:

     - personal injuries;

     - property and natural resource damages;

     - oil spills and releases or discharges of hazardous materials;

     - well reclamation costs;

     - remediation and clean-up costs and other governmental sanctions, such as
       fines and penalties; and

     - other environmental damages.

     Our operations could be significantly delayed or curtailed and our costs of
operations could significantly increase as a result of regulatory requirements
or restrictions. We are unable to predict the ultimate cost of compliance with
these requirements or their effect on our operations.

  WE CANNOT CONTROL ACTIVITIES ON PROPERTIES WE DO NOT OPERATE. INABILITY TO
  FUND OUR CAPITAL EXPENDITURES MAY RESULT IN REDUCTION OR FORFEITURE OF OUR
  INTERESTS IN SOME OF OUR NON-OPERATED PROJECTS.

     Other companies operate approximately 21% of the net present value of our
current reserves, which include reserves added to our reserve base as a result
of the Acquisition, and we have limited ability to exercise influence over
operations for these properties or their associated costs. Our dependence on the
operator and other working interest owners for these projects and our limited
ability to influence operations and associated costs could prevent the
realization of our targeted returns on capital in drilling or acquisition
activities. The success and timing of drilling and exploitation activities on
properties operated by others, therefore, depend upon a number of factors that
will be outside our control, including:

     - timing and amount of capital expenditures;

     - the operator's expertise and financial resources;

     - approval of other participants in drilling wells; and

     - selection of technology.

     Where we are not the majority owner or operator of a particular oil and
natural gas project, we may have no control over the timing or amount of capital
expenditures associated with such project. If we are not willing to fund our
capital expenditures relating to such projects when required by the majority
owner or operator, our interests in these projects may be reduced or forfeited.

                                        18


  OUR BUSINESS INVOLVES MANY OPERATING RISKS THAT MAY RESULT IN SUBSTANTIAL
  LOSSES. INSURANCE MAY BE UNAVAILABLE OR INADEQUATE TO PROTECT US AGAINST THESE
  RISKS.

     Our operations are subject to hazards and risks inherent in drilling for,
producing and transporting oil and natural gas, such as:

     - fires;

     - natural disasters;

     - explosions;

     - formations with abnormal pressures;

     - casing collapses;

     - embedded oilfield drilling and service tools;

     - uncontrollable flows of underground natural gas, oil and formation water;

     - surface cratering;

     - pipeline ruptures or cement failures; and

     - environmental hazards such as natural gas leaks, oil spills and
       discharges of toxic gases.

     Any of these risks can cause substantial losses resulting from:

     - injury or loss of life;

     - damage to and destruction of property, natural resources and equipment;

     - pollution and other environmental damage;

     - regulatory investigations and penalties;

     - suspension of operations; and

     - repair and remediation costs.

     As protection against operating hazards, we maintain insurance coverage
against some, but not all, potential losses. However, losses could occur for
uninsurable or uninsured risks, or in amounts in excess of existing insurance
coverage. The occurrence of an event that is not fully covered by insurance
could harm our financial condition and results of operations.

  WE ARE VULNERABLE TO RISKS ASSOCIATED WITH OPERATING IN THE GULF OF MEXICO.

     Our operations and financial results could be significantly impacted by
conditions in the Gulf of Mexico because we explore and produce extensively in
that area. As a result of this activity, we are vulnerable to the risks
associated with operating in the Gulf of Mexico, including those relating to:

     - adverse weather conditions;

     - oil field service costs and availability;

     - compliance with environmental and other laws and regulations;

     - remediation and other costs resulting from oil spills or releases of
       hazardous materials; and

     - failure of equipment or facilities.

     For example, in 2002, adverse weather conditions caused us to temporarily
shut-in our offshore operations and reduce production, which resulted in a
decline in production by 0.9 Bcf.

     In addition, we intend to conduct some of our exploration in the deep
waters (greater than approximately 1,000 feet) of the Gulf of Mexico, where
operations are more difficult and costly than in shallower waters. The

                                        19


deep waters in the Gulf of Mexico lack the physical and oilfield service
infrastructure present in its shallower waters. As a result, deep water
operations may require a significant amount of time between a discovery and the
time that we can market our production, thereby increasing the risk involved
with these operations.

     Further, production of reserves from reservoirs in the Gulf of Mexico
generally declines more rapidly than from reservoirs in many other producing
regions of the world. This results in recovery of a relatively higher percentage
of reserves from properties in the Gulf of Mexico during the initial few years
of production, and as a result, our reserve replacement needs from new prospects
may be greater there than for our operations elsewhere. Also, our revenues and
return on capital will depend significantly on prices prevailing during these
relatively short production periods.

  WE DEPEND UPON OUR MANAGEMENT TEAM, AND OUR OPERATIONS REQUIRE US TO ATTRACT
  AND RETAIN EXPERIENCED TECHNICAL PERSONNEL.

     The successful implementation of our strategies and handling of other
issues integral to our future success will depend, in part, on our experienced
management team. The loss of members of our management team could have an
adverse effect on our business. Our exploratory drilling success and the success
of other activities integral to our operations will depend, in part, on our
ability to attract and retain experienced explorationists, engineers and other
professionals. Competition for experienced explorationists, engineers and some
other professionals is extremely intense. If we cannot retain our technical
personnel or attract additional experienced technical personnel, our ability to
compete could be harmed.

  THE MARKETABILITY OF OUR PRODUCTION DEPENDS UPON FACTORS OVER WHICH WE MAY
  HAVE NO CONTROL.

     The marketability of our production depends in part upon the availability,
proximity and capacity of pipelines, natural gas gathering systems and
processing facilities. Any significant change in market factors affecting these
infrastructure facilities could adversely impact our ability to deliver the oil
and natural gas we produce to market in an efficient manner, which could harm
our financial condition and results of operations. We deliver oil and natural
gas through gathering systems and pipelines that we do not own. These facilities
may not be available to us in the future. Our ability to produce and market oil
and natural gas is affected and may be also harmed by:

     - Federal and state regulation of oil and natural gas production;

     - transportation, tax and energy policies;

     - changes in supply and demand; and

     - general economic conditions.

  OUR PRINCIPAL STOCKHOLDERS OWN A SIGNIFICANT AMOUNT OF OUR COMMON STOCK,
  GIVING THEM A CONTROLLING INFLUENCE OVER CORPORATE TRANSACTIONS AND OTHER
  MATTERS.

     As of December 31, 2002, after the closing of the November 19, 2002 private
equity offering and December 16, 2002 shelf offering, our principal
stockholders, including Westport Energy LLC, ERI Investments, Inc., an affiliate
of Equitable Resources Corp., and the Belfer Group, a group of former
stockholders of Belco Oil & Gas Corp., together beneficially own approximately
53% of our outstanding common stock. Accordingly, these stockholders, acting
together through a shareholders agreement, will continue to be able to control
the outcome of the election of directors as well as, if they choose to act
together, the adoption or amendment of provisions in our articles of
incorporation or bylaws and the approval of mergers and other significant
corporate transactions. These factors may also delay or prevent a change in our
management or voting control.

  OUR OIL AND GAS MARKETING ACTIVITIES MAY EXPOSE US TO CLAIMS FROM ROYALTY
  OWNERS.

     In addition to marketing our oil and gas production, our marketing
activities generally include marketing oil and gas production for royalty
owners. Recently, royalty owners have commenced litigation against a

                                        20


number of companies in the oil and gas production business claiming that amounts
paid for production attributable to the royalty owners' interest violated the
terms of the applicable leases and laws in various respects, including the value
of production sold, permissibility of deductions taken and accuracy of
quantities measured. Some of this litigation was commenced as class action suits
including two class action suits filed against Westport involving some of our
Wyoming properties. Although we believe payments, if any, that we are required
to make under existing litigation would not have a material impact on our
financial condition, our liability relating to the marketing of oil and gas may
increase as new cases are decided and the law in this area continues to develop.

RISKS RELATING TO OUR INDEBTEDNESS

  OUR LEVERAGE AND DEBT SERVICE OBLIGATIONS MAY ADVERSELY AFFECT OUR CASH FLOW
  AND OUR ABILITY TO MAKE PAYMENTS ON THE NOTES.

     As of September 30, 2002, after giving pro forma effect to the Transactions
and the application of the actual and estimated net proceeds from the Offerings
and the borrowings under our Replacement Credit Facility, we would have had
total debt of $792 million and stockholders' equity of $1,156 million.

     Our level of debt could have important consequences for you, including the
following:

     - it may be more difficult for us to satisfy our obligations with respect
       to the notes;

     - we may have difficulties borrowing money in the future for acquisitions,
       to meet our operating expenses or other purposes;

     - the amount of our interest expense may increase because certain of our
       borrowings are at variable rates of interest, which, if interest rates
       increase, could result in higher interest expense;

     - we will need to use a portion of the money we earn to pay principal and
       interest on our debt which will reduce the amount of money we have to
       finance our operations and other business activities;

     - we may have a higher level of debt than some of our competitors, which
       may put us at a competitive disadvantage;

     - we may be more vulnerable to economic downturns and adverse developments
       in our industry; and

     - our debt level could limit our flexibility in planning for, or reacting
       to, changes in our business and the industry in which we operate.

     Our ability to meet our expenses and debt obligations will depend on our
future performance, which will be affected by financial, business, economic,
regulatory and other factors. We will not be able to control many of these
factors, such as economic conditions and governmental regulation. We cannot be
certain that our earnings will be sufficient to allow us to pay the principal
and interest on our debt, including the notes, and meet our other obligations.
If we do not have enough money, we may be required to refinance all or part of
our existing debt, including the notes, sell assets, borrow more money or raise
equity. We may not be able to refinance our debt, sell assets, borrow more money
or raise equity on terms acceptable to us, if at all. Further, failing to comply
with the financial and other restrictive covenants in our indebtedness could
result in an event of default under such indebtedness, which could adversely
affect our business, financial condition and results of operations.

  WE MAY BE ABLE TO INCUR SUBSTANTIALLY MORE DEBT. ADDITIONAL DEBT COULD
  EXACERBATE THE RISKS DESCRIBED ABOVE.

     Together with our subsidiaries, we may be able to incur substantially more
debt in the future. Although the Indenture governing the notes contains
restrictions on our incurrence of additional indebtedness, these restrictions
are subject to a number of qualifications and exceptions, and under certain
circumstances, indebtedness incurred in compliance with these restrictions could
be substantial. Also, these restrictions do not prevent us from incurring
obligations that do not constitute indebtedness. As of January 15, 2003, we had
approximately $359 million of additional borrowing capacity under the
Replacement Credit Facility, which
                                        21


capacity reflects the Transactions and the application of the net proceeds from
the Offerings and the borrowings under our Replacement Credit Facility and is
subject to specific requirements, including compliance with financial covenants.
To the extent new debt is added to our current debt levels, the risks described
above could substantially increase.

  ANY FAILURE TO MEET OUR DEBT OBLIGATIONS COULD HARM OUR BUSINESS, FINANCIAL
  CONDITION AND RESULTS OF OPERATIONS.

     If our cash flow and capital resources are insufficient to fund our debt
obligations, we may be forced to sell assets, seek additional equity or debt
capital or restructure our debt. In addition, any failure to make scheduled
payments of interest and principal on our outstanding indebtedness would likely
result in a reduction of our credit rating, which could harm our ability to
incur additional indebtedness on acceptable terms. Our cash flow and capital
resources may be insufficient for payment of interest on and principal of our
debt in the future, including payments on the notes, and any such alternative
measures may be unsuccessful or may not permit us to meet scheduled debt service
obligations, which could cause us to default on our obligations and could impair
our liquidity.

RISKS RELATING TO THE EXCHANGE NOTES

  SUBORDINATION OF THE NOTES MAY LIMIT PAYMENT ON THE NOTES, INCLUDING PAYMENT
  ON THE EXCHANGE NOTES.

     Our obligations under the terms of the notes, including the exchange notes,
are subordinated in right of payment to all of our existing and future Senior
Indebtedness, including outstanding borrowings under the Replacement Credit
Facility. As of September 30, 2002, as adjusted to give effect to the
Transactions, and the application of the actual and estimated net proceeds from
the Offerings and the borrowings under our Replacement Credit Facility, we would
have had approximately $109 million of Senior Indebtedness outstanding. We may
incur additional Senior Indebtedness from time to time, subject to certain
restrictions imposed by the Indenture governing the notes. By reason of the
subordination of the notes, including the exchange notes, in the event of our
insolvency, liquidation or other reorganization, creditors who are holders of
Senior Indebtedness must be paid in full before any payments may be made to
holders of the notes, including the exchange notes. There may not be sufficient
assets remaining after payment of prior claims to pay amounts due on the notes,
including the exchange notes. In addition, under certain circumstances, no
payments may be made with respect to the notes, including the exchange notes, if
a default exists with respect to Senior Indebtedness. See "Description of
Exchange Notes -- Ranking." The term "Senior Indebtedness" is defined in
"Description of Exchange Notes -- Certain Definitions."

  FEDERAL AND STATE STATUTES ALLOW COURTS, UNDER SPECIFIC CIRCUMSTANCES, TO VOID
  GUARANTEES AND REQUIRE NOTEHOLDERS TO RETURN PAYMENTS RECEIVED FROM
  GUARANTORS.

     Federal and state statutes allow courts, under specific circumstances, to
void guarantees and require creditors such as the noteholders to return payments
received from guarantors. Under federal bankruptcy law and comparable provisions
of state fraudulent transfer laws, a guarantee could be voided or claims in
respect of a guarantee could be subordinated to all other debts of that
guarantor if, for example, the guarantor, at the time it issued its guarantee:

     - intended to hinder, delay or defraud any present or future creditor or
       received less than reasonably equivalent value or fair compensation for
       the guarantee;

     - was insolvent or rendered insolvent by making the guarantee;

     - was engaged in a business or transaction for which the guarantor's
       remaining assets constituted unreasonably small capital; or

     - intended to incur, or believed that it would incur, debts beyond its
       ability to pay them as they mature.

                                        22


     The measures of insolvency for purposes of these fraudulent transfer laws
will vary depending upon the law applied in any proceeding to determine whether
a fraudulent transfer has occurred. Generally, a guarantor would be considered
insolvent if:

     - the sum of its debts, including contingent liabilities, was greater than
       the fair saleable value of all of its assets;

     - the present fair saleable value of its assets was less than the amount
       that would be required to pay its probable liability on its existing
       debts, including contingent liabilities, as they become absolute and
       mature; or

     - it could not pay its debts as they become due.

     On the basis of historical financial information, recent operating history
and other factors, we believe that the subsidiary guaranties are being incurred
for proper purposes and in good faith and that each guarantor, after giving
effect to its guarantee of the exchange notes, will not be insolvent, have
unreasonably small capital for the business in which it is engaged or have
incurred debts beyond its ability to pay as they mature. We cannot be certain,
however, that a court would agree with our conclusions in this regard.

  WE ARE SUBJECT TO RESTRICTIVE DEBT COVENANTS.

     The Replacement Credit Facility contains covenants that are similar to, but
more restrictive to us than, those contained in the Indenture governing the
notes, and requires us to maintain specified financial ratios.

     Our ability to meet those financial ratios can be affected by events beyond
our control, and we cannot assure you that we will meet those ratios. A breach
of any of these covenants, ratios or restrictions could result in an event of
default under the Replacement Credit Facility. Upon the occurrence of an event
of default under the Replacement Credit Facility, the lenders could elect to
declare all amounts outstanding under the facility, together with accrued
interest, to be immediately due and payable. If we were unable to repay those
amounts, the lenders could proceed against the collateral granted to them to
secure the indebtedness. If the lenders under the Replacement Credit Facility
accelerate the payment of the indebtedness, we cannot assure you that our assets
would be sufficient to repay in full that indebtedness and our other
indebtedness, including the exchange notes.

  A FINANCIAL FAILURE BY US OR ANY SUBSIDIARY GUARANTOR MAY HINDER THE RECEIPT
  OF PAYMENT ON THE EXCHANGE NOTES, AS WELL AS THE ENFORCEMENT OF REMEDIES UNDER
  THE SUBSIDIARY GUARANTIES.

     An investment in the exchange notes, as in any type of security, involves
insolvency and bankruptcy considerations that investors should carefully
consider. If we or any of our subsidiary guarantors become a debtor subject to
insolvency proceedings under the bankruptcy code, it is likely to result in
delays in the payment of the exchange notes and in the exercise of enforcement
remedies under the exchange notes or the subsidiary guaranties. Provisions under
the bankruptcy code or general principles of equity that could result in the
impairment of your rights include the automatic stay, avoidance of preferential
transfers by a trustee or a debtor-in-possession, substantive consolidation,
limitations of collectability of unmatured interest or attorneys' fees and
forced restructuring of the exchange notes.

  A FINANCIAL FAILURE BY US MAY RESULT IN THE ASSETS OF ANY OR ALL SUBSIDIARIES
  BECOMING SUBJECT TO THE CLAIMS OF OUR CREDITORS.

     A financial failure by us could affect payment of the exchange notes if a
bankruptcy court were to "substantively consolidate" us and our subsidiaries. If
a bankruptcy court substantively consolidated us and our subsidiaries, the
assets of each entity would be subject to the claims of creditors of all
entities. This would expose you not only to the usual impairments arising from
bankruptcy, but also to potential dilution of the amount ultimately recoverable
because of the larger creditor base. Furthermore, forced restructuring of the
exchange notes could occur through the "cram-down" provision of the bankruptcy
code. Under this provision, the exchange notes could be restructured over your
objections as to their general terms, primarily interest rate and maturity.
                                        23


RISKS RELATED TO THE EXCHANGE OFFER

  THERE IS NO ACTIVE TRADING MARKET FOR THE EXCHANGE NOTES, THE VALUE OF THE
  EXCHANGE NOTES MAY FLUCTUATE SIGNIFICANTLY AND ANY MARKET FOR THE EXCHANGE
  NOTES MAY BE ILLIQUID.

     The exchange notes will be a new issue of debt securities of the same class
as the initial exchange notes and will generally be freely transferable.
Notwithstanding the foregoing, we cannot assure you that a liquid market will
develop for the exchange notes or that you will be able to sell your exchange
notes at a particular time, as we do not intend to apply for the exchange notes
to be listed on any securities exchange or to arrange for quotation on any
automated dealer quotation system. In addition, the trading prices of the
exchange notes could be subject to significant fluctuations in response to
government regulations, variations in quarterly operating results, demand for
oil and natural gas, general economic conditions and various other factors. The
liquidity of the trading market in the exchange notes and the market price
quoted for the exchange notes may also be adversely affected by changes in the
overall market for high yield securities and by changes in our financial
performance or prospects or in the prospects for companies in our industry
generally. As a result, we can give you no assurance that an active trading
market will develop for the exchange notes. If no active trading market
develops, you may not be able to resell your exchange notes at their fair market
value or at all. This offer to exchange the exchange notes for the old notes
does not depend on any minimum amount of the old notes being tendered for
exchange.

  IF YOU DO NOT EXCHANGE YOUR OLD NOTES, THEY MAY BE DIFFICULT TO RESELL.

     It may be difficult for you to sell the old notes that are not exchanged in
the exchange offer, since any old notes not exchanged will remain subject to the
restrictions on transfer provided for in Rule 144 under the Securities Act.
These restrictions on transfer of your old notes exist because we issued the old
notes pursuant to an exemption from the registration requirements of the
Securities Act and applicable state securities laws. Generally, the old notes
that are not exchanged for the exchange notes pursuant to the exchange offer
will remain restricted securities. Accordingly, such old notes may be resold
only:

     - to us (upon redemption of the notes or otherwise);

     - pursuant to an effective registration statement under the Securities Act;

     - so long as the old notes are eligible for resale pursuant to Rule 144A
       under the Securities Act to a qualified institutional buyer within the
       meaning of Rule 144A in a transaction meeting the requirements of Rule
       144A;

     - outside the United States to a foreign person pursuant to the exemption
       from the registration requirements of the Securities Act provided by
       Regulation S under the Securities Act;

     - pursuant to an exemption from registration under the Securities Act
       provided by Rule 144 thereunder (if available); or

     - pursuant to another available exemption from the registration
       requirements of the Securities Act, in each case in accordance with any
       applicable securities laws of any state of the United States.

     Except as provided in this exchange offer, we do not intend to register the
old notes under the Securities Act. To the extent any old notes are tendered and
accepted in the exchange offer, the trading market, if any, for the old notes
that remain outstanding after the exchange offer would be adversely affected due
to a reduction in market liquidity.

                                        24


                               THE EXCHANGE OFFER

     This section of the prospectus describes the proposed exchange offer. While
we believe that the description covers the material terms of the exchange offer,
this summary may not contain all of the information that is important to you.
You should carefully read this entire document and the other documents referred
to herein for a more complete understanding of the exchange offer.

PURPOSE OF THE EXCHANGE OFFER

     In connection with the issuance of the old notes, we entered into a
registration rights agreement that provides for the exchange offer. A copy of
the registration rights agreement relating to the old notes is filed as an
exhibit to the registration statement of which this prospectus is a part. Under
the registration rights agreement relating to the old notes we agreed that we
would, subject to certain exceptions:

     - within 75 days after the issue date of the old notes, file a registration
       statement with the SEC with respect to a registered offer to exchange the
       old notes for the exchange notes having terms substantially identical in
       all material respects to the old notes (except that the exchange notes
       will not contain terms with respect to transfer restrictions and will
       have different administrative terms);

     - use our reasonable best efforts to cause the registration statement to be
       declared effective under the Securities Act within 180 days after the
       issue date of the old notes;

     - following the declaration of the effectiveness of the registration
       statement, promptly offer the exchange notes in exchange for surrender of
       the old notes; and

     - keep the exchange offer open for not less than 30 days (or longer if
       required by applicable law) after the date notice of the exchange offer
       is mailed to the holders of the old notes.

     For each old note tendered to us pursuant to the exchange offer, we will
issue to the holder of such old note an exchange note having a principal amount
equal to that of the surrendered old note. Interest on each exchange note will
accrue from the last interest payment date on which interest was paid on the old
note surrendered in exchange therefor, or, if no interest has been paid on such
old note, from November 1, 2002.

     Under existing SEC interpretations, the exchange notes will be freely
transferable by holders other than our affiliates after the exchange offer
without further registration under the Securities Act if the holder of the
exchange notes represents to us in the exchange offer that it is acquiring the
exchange notes in the ordinary course of its business, that it has no
arrangement or understanding with any person to participate in the distribution
of the exchange notes and that it is not an affiliate of ours, as such terms are
interpreted by the SEC; provided, however, that broker-dealers receiving the
exchange notes in the exchange offer will have a prospectus delivery requirement
with respect to resales of such exchange notes. The SEC has taken the position
that such participating broker-dealers may fulfill their prospectus delivery
requirements with respect to the exchange notes (other than a resale of an
unsold allotment from the original sale of the old notes) with the prospectus
contained in this registration statement. Each broker-dealer that receives the
exchange notes for its own account in exchange for the old notes, where such old
notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such exchange notes. See "Plan of
Distribution."

     Under the registration rights agreement relating to the old notes, we are
required to allow participating broker-dealers and other persons, if any, with
similar prospectus delivery requirements to use the prospectus contained in this
registration statement in connection with the resale of the exchange notes for
180 days following the effective date of such registration statement (or such
shorter period during which participating broker-dealers are required by law to
deliver such prospectus).

     A holder of old notes (other than certain specified holders) who wishes to
exchange the old notes for the exchange notes in the exchange offer will be
required to represent that any exchange notes to be received by it will be
acquired in the ordinary course of its business and that at the time of the
commencement of the exchange offer it has no arrangement or understanding with
any person to participate in the distribution (within the meaning of the
Securities Act) of the exchange notes and that it is not an "affiliate" of ours,
as
                                        25


defined in Rule 405 of the Securities Act, or if it is an affiliate, that it
will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable.

     In the event that:

          (1) any change of law or in applicable interpretations thereof by the
     staff of the SEC do not permit us to effect an exchange offer; or

          (2) for any other reason we do not consummate the exchange offer
     within 220 days of the issue date of the old notes; or

          (3) an initial purchaser of the old notes notifies us following
     consummation of the exchange offer that the old notes held by it are not
     eligible to be exchanged for the exchange notes in the exchange offer; or

          (4) certain holders of the old notes are not eligible to participate
     in the exchange offer or may not resell the exchange notes acquired by them
     in the exchange offer to the public without delivering a prospectus,

then, we will, subject to certain exceptions,

          (1) file a shelf registration statement with the SEC covering resales
     of the old notes or the exchange notes, as the case may be, on or prior to
     the date (which we call the shelf filing date) which is the 75th day after
     the date on which the obligation to file the shelf registration statement
     arises;

          (2) use our reasonable best efforts to cause the shelf registration
     statement to be declared effective under the Securities Act on or prior to
     the 75th day after the shelf filing date; and

          (3) use our reasonable best efforts to keep the shelf registration
     statement effective until the earliest of (A) the time when the old notes
     or the exchange notes covered by the shelf registration statement can be
     sold pursuant to Rule 144 without any limitations under Rule 144, (B) two
     years from the effective date of the shelf registration statement and (C)
     the date on which all old notes or exchange notes registered thereunder are
     disposed of in accordance therewith.

     We will, in the event a shelf registration statement is filed, among other
things, provide to each holder for whom such shelf registration statement was
filed copies of the prospectus which is a part of the shelf registration
statement, notify each such holder when the shelf registration statement has
become effective and take certain other actions as are required to permit
unrestricted resales of the old notes or the exchange notes, as the case may be.
A holder selling such old notes or exchange notes pursuant to the shelf
registration statement generally would be required to be named as a selling
security holder in the related prospectus and to deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the registration rights agreement that are applicable to such
holder (including certain indemnification obligations).

     We will pay additional cash interest on the applicable old notes and
exchange notes, subject to certain exceptions:

          (1) if we fail to file the registration statement of which this
     prospectus forms a part with the SEC on or prior to the 75th day after the
     issue date of the old notes;

          (2) if the registration statement of which this prospectus forms a
     part is not declared effective by the SEC on or prior to the 180th day
     after the issue date of the old notes;

          (3) if the exchange offer is not consummated on or before the 40th day
     after the registration statement of which this prospectus forms a part is
     declared effective;

          (4) if obligated to file the shelf registration statement, we fail to
     file the shelf registration statement with the SEC on or prior to the shelf
     filing date;

          (5) if obligated to file a shelf registration statement, the shelf
     registration statement is not declared effective on or prior to the 75th
     day after the shelf filing date; or
                                        26


          (6) after the registration statement of which this prospectus forms a
     part or the shelf registration statement, as the case may be, is declared
     effective, such registration statement thereafter ceases to be effective or
     usable (subject to certain exceptions);

from and including the date on which any such default shall occur to but
excluding the date on which all such defaults have been cured.

     The rate of any such additional interest will be 0.50% per annum. We will
pay any such additional interest on regular interest payment dates. Such
additional interest will be in addition to any other interest payable from time
to time with respect to the old notes and the exchange notes.

     All references in the Indenture, in any context, to any interest or other
amount payable on or with respect to the old notes or the exchange notes shall
be deemed to include any additional interest pursuant to the registration rights
agreement relating to the old notes.

     If we effect the exchange offer, we will be entitled to close the exchange
offer 30 days after the commencement thereof provided that we have accepted all
old notes theretofore validly tendered in accordance with the terms of the
exchange offer.

BACKGROUND OF THE EXCHANGE OFFER

     We issued an aggregate of $300 million principal amount of old notes on
December 17, 2002 under the Indenture. The old notes were issued as additional
debt securities under the Indenture pursuant to which, on November 5, 2001, we
issued $275 million principal amount of our unregistered 8 1/4% Senior
Subordinated Notes Due 2011, all of which were exchanged for an equal principal
amount of the initial exchange notes on March 14, 2002. The maximum principal
amount of the exchange notes that will be issued in this exchange offer for the
old notes is $300 million. The terms of the exchange notes and the old notes
will be identical in all material respects, except for transfer restrictions and
registration rights that will not apply to the exchange notes, and different
administrative terms.

     The exchange notes, any old notes not exchanged in the exchange offer and
the initial exchange notes will constitute a single class of debt securities
under the Indenture. The exchange notes, together with any old notes that are
not exchanged in the exchange offer, will represent approximately 52% of all
notes issued under the Indenture as of the date of the closing of the exchange
offer.

     The exchange notes will bear interest at a rate of 8 1/4% per year, payable
semiannually on May 1 and November 1 of each year, beginning on May 1, 2003.
Interest on each exchange note will accrue from the last interest payment date
on which interest was paid on the old note surrendered in exchange therefor, or,
if no interest has been paid on such note, from November 1, 2002. Holders of the
exchange notes will not receive any interest on old notes tendered and accepted
for exchange.

     In order to exchange your old notes for the exchange notes containing no
transfer restrictions in the exchange offer, you will be required to make the
following representations:

     - the exchange notes will be acquired in the ordinary course of your
       business;

     - you have no arrangements with any person to participate in the
       distribution of the exchange notes; and

     - you are not our "affiliate" as defined in Rule 405 of the Securities Act,
       or if you are an affiliate of ours, you will comply with the applicable
       registration and prospectus delivery requirements of the Securities Act.

     Upon the terms and subject to the conditions set forth in this prospectus
and in the letter of transmittal, we will accept for exchange any old notes
properly tendered and not validly withdrawn in the exchange offer, and the
exchange agent will deliver the exchange notes promptly after the expiration
date of the exchange offer. We expressly reserve the right to delay acceptance
of any of the tendered old notes or terminate the exchange offer and not accept
for exchange any tendered old notes not already accepted if any conditions set
forth under "-- Conditions to the Exchange Offer" have not been satisfied or
waived by us or do not comply, in whole or in part, with any applicable law.
                                        27


     If you tender your old notes, you will not be required to pay brokerage
commissions or fees or, subject to the instructions in the letter of
transmittal, transfer taxes with respect to the exchange of the old notes. We
will pay all charges, expenses and transfer taxes in connection with the
exchange offer, other than certain taxes described below under "-- Transfer
Taxes."

EXPIRATION DATE; EXTENSIONS; TERMINATION; AMENDMENTS

     The exchange offer will expire at 5:00 p.m., New York City time, on
          , 2003, unless we extend it. We expressly reserve the right to extend
the exchange offer on a daily basis or for such period or periods as we may
determine in our sole discretion from time to time by giving oral, confirmed in
writing, or written notice to the exchange agent and by making a public
announcement by press release to the Dow Jones News Service prior to 9:00 a.m.,
New York City time, on the first business day following the previously scheduled
expiration date. During any extension of the exchange offer, all old notes
previously tendered, not validly withdrawn and not accepted for exchange will
remain subject to the exchange offer and may be accepted for exchange by us.

     To the extent we are legally permitted to do so, we expressly reserve the
absolute right, in our sole discretion, but are not required, to:

     - waive any condition of the exchange offer; and

     - amend any terms of the exchange offer.

     Any waiver or amendment to the exchange offer will apply to all old notes
tendered, regardless of when or in what order the old notes were tendered. If we
make a material change in the terms of the exchange offer or if we waive a
material condition of the exchange offer, we will disseminate additional
exchange offer materials, and we will extend the exchange offer to the extent
required by law.

     We expressly reserve the right, in our sole discretion, to terminate the
exchange offer if any of the conditions set forth under "-- Conditions of the
Exchange Offer" exist. Any such termination will be followed promptly by a
public announcement. In the event we terminate the exchange offer, we will give
immediate notice to the exchange agent, and all old notes previously tendered
and not accepted for exchange will be returned promptly to the tendering
holders.

     In the event that the exchange offer is withdrawn or otherwise not
completed, the exchange notes will not be given to holders of old notes who have
validly tendered their old notes. We will return any old notes that have been
tendered for exchange but that are not exchanged for any reason to their holder
without cost to the holder, or, in the case of the old notes tendered by
book-entry transfer into the exchange agent's account at a book-entry transfer
facility under the procedure set forth under "-- Procedures for Tendering Old
Notes-Book-Entry Transfer," such old notes will be credited to the account
maintained at such book-entry transfer facility from which such old notes were
delivered, unless otherwise requested by such holder under "-- Special Delivery
Instructions" in the letter of transmittal, promptly following the exchange date
or the termination of the exchange offer.

RESALE OF THE EXCHANGE NOTES

     Based on interpretations of the SEC set forth in no-action letters issued
to third parties, we believe that the exchange notes issued under the exchange
offer in exchange for the old notes may be offered for resale, resold and
otherwise transferred by you without compliance with the registration and
prospectus delivery provisions of the Securities Act, if:

     - you are not an "affiliate" of ours within the meaning of Rule 405 under
       the Securities Act;

     - you are acquiring the exchange notes in the ordinary course of your
       business; and

     - you do not intend to participate in the distribution of the exchange
       notes.

                                        28


     If you tender old notes in the exchange offer with the intention of
participating in any manner in a distribution of the exchange notes:

     - you cannot rely on those interpretations of the SEC; and

     - you must comply with the registration and prospectus delivery
       requirements of the Securities Act in connection with a secondary resale
       transaction, and the secondary resale transaction must be covered by an
       effective registration statement containing the selling security holder
       information required by Item 507 or 508, as applicable, of Regulation S-K
       under the Securities Act.

     Unless an exemption from registration is otherwise available, any security
holder intending to distribute the exchange notes should be covered by an
effective registration statement under the Securities Act containing the selling
security holder's information required by Item 507 of Regulation S-K. This
prospectus may be used for an offer to resell, a resale or other re-transfer of
the exchange notes only as specifically set forth in the section captioned "Plan
of Distribution." Only broker-dealers that acquired the exchange notes as a
result of market-making activities or other trading activities may participate
in the exchange offer. Each broker-dealer that receives the exchange notes for
its own account in exchange for old notes, where such old notes were acquired by
such broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of the exchange notes. Please read the section captioned "Plan
of Distribution" for more details regarding the transfer of the exchange notes.

ACCEPTANCE OF OLD NOTES FOR EXCHANGE

     We will accept for exchange old notes validly tendered pursuant to the
exchange offer, or defectively tendered, if such defect has been waived by us,
after the later of:

     - the expiration date of the exchange offer; and

     - the satisfaction or waiver of the conditions specified below under
       "-- Conditions of the Exchange Offer."

     Except as specified above, we will not accept old notes for exchange
subsequent to the expiration date of the exchange offer. Tenders of old notes
will be accepted only in principal amounts equal to $1,000 or integral multiples
thereof.

     We expressly reserve the right, in our sole discretion, to:

     - delay acceptance for exchange of old notes tendered under the exchange
       offer, subject to Rule 14e-1 under the Exchange Act, which requires that
       an offeror pay the consideration offered or return the securities
       deposited by or on behalf of the holders promptly after the termination
       or withdrawal of a tender offer; or

     - terminate the exchange offer and not accept for exchange any old notes,
       if any of the conditions set forth below under "-- Conditions of the
       Exchange Offer" have not been satisfied or waived by us or in order to
       comply in whole or in part with any applicable law.

     In all cases, the exchange notes will be issued only after timely receipt
by the exchange agent of certificates representing old notes, or confirmation of
book-entry transfer, a properly completed and duly executed letter of
transmittal, or a manually signed facsimile thereof, and any other required
documents. For purposes of the exchange offer, we will be deemed to have
accepted for exchange validly tendered old notes, or defectively tendered old
notes with respect to which we have waived such defect, if, as and when we give
oral, confirmed in writing, or written notice to the exchange agent. Promptly
after the expiration date, we will deposit the exchange notes with the exchange
agent, who will act as agent for the tendering holders for the purpose of
receiving the exchange notes and transmitting them to the holders. The exchange
agent will deliver the exchange notes to holders of old notes accepted for
exchange after the exchange agent receives the exchange notes.

     If, for any reason, we delay acceptance for exchange of validly tendered
old notes or we are unable to accept for exchange validly tendered old notes,
then the exchange agent may, nevertheless, on its behalf, retain
                                        29


tendered old notes, without prejudice to our rights described in this prospectus
under the captions "-- Expiration Date; Extensions; Termination; Amendments,"
"-- Conditions of the Exchange Offer" and "-- Withdrawal of Tenders," subject to
Rule 14e-1 under the Securities Exchange Act of 1934, which requires that an
offeror pay the consideration offered or return the securities deposited by or
on behalf of the holders thereof promptly after the termination or withdrawal of
a tender offer.

     If any tendered old notes are not accepted for exchange for any reason, or
if certificates are submitted evidencing more old notes than those that are
tendered, certificates evidencing old notes that are not exchanged will be
returned, without expense, to the tendering holder, or, in the case of the old
notes tendered by book-entry transfer into the exchange agent's account at a
book-entry transfer facility under the procedure set forth under "-- Procedures
for Tendering Old Notes-Book-Entry Transfer," such old notes will be credited to
the account maintained at such book-entry transfer facility from which such old
notes were delivered, unless otherwise requested by such holder under
"-- Special Delivery Instructions" in the letter of transmittal, promptly
following the exchange date or the termination of the exchange offer.

     Tendering holders of old notes exchanged in the exchange offer will not be
obligated to pay brokerage commissions or transfer taxes with respect to the
exchange of their old notes other than as described under the caption
"-- Transfer Taxes" or as set forth in the letter of transmittal. We will pay
all other charges and expenses in connection with the exchange offer.

PROCEDURES FOR TENDERING OLD NOTES

     Any beneficial owner whose old notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee or held through
a book-entry transfer facility and who wishes to tender old notes should contact
such registered holder promptly and instruct such registered holder to tender
old notes on such beneficial owner's behalf.

  TENDER OF OLD NOTES HELD THROUGH THE DEPOSITORY TRUST COMPANY

     The exchange agent and The Depository Trust Company, or DTC, have confirmed
that the exchange offer is eligible for the DTC automated tender offer program.
Accordingly, DTC participants may electronically transmit their acceptance of
the exchange offer by causing DTC to transfer old notes to the exchange agent in
accordance with DTC's automated tender offer program procedures for transfer.
DTC will then send an agent's message to the exchange agent.

     The term "agent's message" means a message transmitted by DTC and received
by the exchange agent that forms part of the book-entry confirmation. The
agent's message states that DTC has received an express acknowledgment from the
participant in DTC tendering old notes that are the subject of that book-entry
confirmation, that the participant has received and agrees to be bound by the
terms of the letter of transmittal, and that we may enforce such agreement
against such participant. In the case of an agent's message relating to
guaranteed delivery, the term means a message transmitted by DTC and received by
the exchange agent, which states that DTC has received an express acknowledgment
from the participant in DTC tendering old notes that they have received and
agree to be bound by the notice of guaranteed delivery.

  TENDER OF OLD NOTES HELD IN PHYSICAL FORM

     For a holder to validly tender old notes held in physical form:

     - the exchange agent must receive at its address set forth in this
       prospectus a properly completed and validly executed letter of
       transmittal, or a manually signed facsimile thereof, together with any
       signature guarantees and any other documents required by the instructions
       to the letter of transmittal; and

     - the exchange agent must receive certificates for tendered old notes at
       such address, or such old notes must be transferred pursuant to the
       procedures for book-entry transfer described above. A confirmation of
       such book-entry transfer must be received by the exchange agent prior to
       the expiration date of the exchange offer. A holder who desires to tender
       old notes and who cannot comply with the procedures
                                        30


       set forth herein for tender on a timely basis or whose old notes are not
       immediately available must comply with the procedures for guaranteed
       delivery set forth below.

     LETTERS OF TRANSMITTAL AND OLD NOTES SHOULD BE SENT ONLY TO THE EXCHANGE
AGENT, AND NOT TO US OR TO ANY BOOK-ENTRY TRANSFER FACILITY.

     THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER TENDERING OLD NOTES. DELIVERY OF SUCH DOCUMENTS WILL BE DEEMED MADE ONLY
WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. IF SUCH DELIVERY IS BY MAIL, WE
SUGGEST THAT THE HOLDER USE PROPERLY INSURED, REGISTERED MAIL WITH RETURN
RECEIPT REQUESTED, AND THAT THE MAILING BE MADE SUFFICIENTLY IN ADVANCE OF THE
EXPIRATION DATE OF THE EXCHANGE OFFER TO PERMIT DELIVERY TO THE EXCHANGE AGENT
PRIOR TO SUCH DATE. NO ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS OF OLD
NOTES WILL BE ACCEPTED.

  SIGNATURE GUARANTEES

     A signature on a letter of transmittal or a notice of withdrawal must be
guaranteed by an eligible institution. Eligible institutions include banks,
brokers, dealers, municipal securities dealers, municipal securities brokers,
government securities dealers, government securities brokers, credit unions,
national securities exchanges, registered securities associations, clearing
agencies and savings associations. The signature need not be guaranteed by an
eligible institution if the old notes are tendered:

     - by a registered holder who has not completed the box entitled "Special
       Registration Instructions" or "Special Delivery Instructions" on the
       letter of transmittal; or

     - for the account of an eligible institution.

     If the letter of transmittal is signed by a person other than the
registered holder of any old notes, the old notes must be endorsed or
accompanied by a properly completed bond power. The bond power must be signed by
the registered holder as the registered holder's name appears on the old notes
and an eligible institution must guarantee the signature on the bond power.

     If the letter of transmittal or any old notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, these
persons should so indicate when signing. Unless we waive this requirement, they
should also submit evidence satisfactory to us of their authority to deliver the
letter of transmittal.

  BOOK-ENTRY TRANSFER

     The exchange agent will seek to establish a new account or utilize an
existing account with respect to the old notes at DTC promptly after the date of
this prospectus. Any financial institution that is a participant in the
book-entry transfer facility system and whose name appears on a security
position listing it as the owner of the old notes may make book-entry delivery
of old notes by causing the book-entry transfer facility to transfer such old
notes into the exchange agent's account. HOWEVER, ALTHOUGH DELIVERY OF OLD NOTES
MAY BE EFFECTED THROUGH BOOK-ENTRY TRANSFER INTO THE EXCHANGE AGENT'S ACCOUNT AT
A BOOK-ENTRY TRANSFER FACILITY, A PROPERLY COMPLETED AND VALIDLY EXECUTED LETTER
OF TRANSMITTAL, OR A MANUALLY SIGNED FACSIMILE THEREOF, MUST BE RECEIVED BY THE
EXCHANGE AGENT AT ITS ADDRESS SET FORTH IN THIS PROSPECTUS ON OR PRIOR TO THE
EXPIRATION DATE OF THE EXCHANGE OFFER, OR ELSE THE GUARANTEED DELIVERY
PROCEDURES DESCRIBED BELOW MUST BE COMPLIED WITH. The confirmation of a
book-entry transfer of old notes into the exchange agent's account at a
book-entry transfer facility is referred to in this prospectus as a "book-entry
confirmation." Delivery of documents to the book-entry transfer facility in
accordance with that book-entry transfer facility's procedures does not
constitute delivery to the exchange agent.

                                        31


  GUARANTEED DELIVERY

     If you wish to tender your old notes and:

     - certificates representing your old notes are not lost but are not
       immediately available;

     - time will not permit your letter of transmittal, certificates
       representing your old notes and all other required documents to reach the
       exchange agent on or prior to the expiration date of the exchange offer;
       or

     - the procedures for book-entry transfer cannot be completed on or prior to
       the expiration date of the exchange offer;

you may tender your old notes if:

     - your tender is made by or through an eligible institution; and

     - on or prior to the expiration date of the exchange offer, the exchange
       agent has received from the eligible institution a properly completed and
       validly executed notice of guaranteed delivery, by manually signed
       facsimile transmission, mail or hand delivery, in substantially the form
       provided with this prospectus:

      - setting forth your name and address, the registered number(s) of your
        old notes and the principal amount of the old notes tendered;

      - stating that the tender is being made by guaranteed delivery; and

      - guaranteeing that, within three New York Stock Exchange trading days
        after the date of the notice of guaranteed delivery, the letter of
        transmittal or facsimile thereof, properly completed and validly
        executed, together with certificates representing the old notes, or a
        book-entry confirmation, and any other documents required by the letter
        of transmittal and the instructions thereto, will be deposited by the
        eligible institution with the exchange agent; and

     - the exchange agent receives the properly completed and validly executed
       letter of transmittal or facsimile thereof with any required signature
       guarantees, together with certificates for all old notes in proper form
       for transfer, or a book-entry confirmation, and any other required
       documents, within three New York Stock Exchange trading days after the
       date of the notice of guaranteed delivery.

  OTHER MATTERS

     Exchange notes will be issued in exchange for old notes accepted for
exchange only after timely receipt by the exchange agent of:

     - certificates for, or a timely book-entry confirmation with respect to,
       your old notes;

     - a properly completed and duly executed letter of transmittal or facsimile
       thereof with any required signature guarantees, or, in the case of a
       book-entry transfer, an agent's message; and

     - any other documents required by the letter of transmittal.

     All questions as to the form of all documents and the validity, including
time of receipt, and acceptance of all tenders of old notes will be determined
by us, in our sole discretion, the determination of which shall be final and
binding. ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS OF OLD NOTES WILL NOT BE
CONSIDERED VALID. We reserve the absolute right to reject any or all tenders of
old notes that are not in proper form or the acceptance of which, in our
opinion, would be unlawful. We also reserve the right to waive any defects,
irregularities or conditions of tender as to any particular old notes. Our
interpretation of the terms and conditions of the exchange offer, including the
instructions in the letter of transmittal, will be final and binding on all
parties.

     Unless waived by us, any defect or irregularity in connection with tenders
of old notes must be cured within the time that we determine. Tenders of old
notes will not be deemed to have been made until all defects and irregularities
have been waived by us or cured. Neither us, the exchange agent, or any other
person will be

                                        32


under any duty to give notice of any defects or irregularities in tenders of old
notes, or will incur any liability to holders for failure to give any such
notice.

     By signing or agreeing to be bound by the letter of transmittal, you will
represent to us that, among other things:

     - any exchange notes that you receive will be acquired in the ordinary
       course of your business;

     - you have no arrangement or understanding with any person or entity to
       participate in the distribution of the exchange notes;

     - if you are not a broker-dealer, that you are not engaged in and do not
       intend to engage in the distribution of the exchange notes;

     - if you are a broker-dealer that will receive the exchange notes for your
       own account in exchange for old notes that were acquired as a result of
       market-making activities or other trading activities, that you will
       deliver a prospectus, as required by law, in connection with any resale
       of the exchange notes; and

     - you are not an "affiliate" of ours, as defined in Rule 405 of the
       Securities Act, or, if you are an affiliate, you will comply with any
       applicable registration and prospectus delivery requirements of the
       Securities Act.

WITHDRAWAL OF TENDERS

     Except as otherwise provided in this prospectus, you may withdraw your
tender of old notes at any time prior to the expiration date of the exchange
offer.

     For a withdrawal to be effective:

     - the exchange agent must receive a written notice of withdrawal at the
       address set forth below under "-- Exchange Agent"; or

     - you must comply with the appropriate procedures of DTC's automated tender
       offer program system.

     Any notice of withdrawal must:

     - specify the name of the person who tendered the old notes to be
       withdrawn; and

     - identify the old notes to be withdrawn, including the principal amount of
       the old notes to be withdrawn.

     If certificates for the old notes have been delivered or otherwise
identified to the exchange agent, then, prior to the release of those
certificates, the withdrawing holder must also submit:

     - the serial numbers of the particular certificates to be withdrawn; and

     - a signed notice of withdrawal with signatures guaranteed by an eligible
       institution, unless the withdrawing holder is an eligible institution.

     If the old notes have been tendered pursuant to the procedure for
book-entry transfer described above, any notice of withdrawal must specify the
name and number of the account at DTC to be credited with the withdrawn old
notes and otherwise comply with the procedures of DTC.

     We will determine all questions as to the validity, form and eligibility,
including time of receipt, of notices of withdrawal, and our determination shall
be final and binding on all parties. We will deem any old notes so withdrawn not
to have been validly tendered for exchange for purposes of the exchange offer.

     We will return any old notes that have been tendered for exchange but that
are not exchanged for any reason to their holder without cost to the holder. In
the case of old notes tendered by book-entry transfer into the exchange agent's
account at DTC, according to the procedures described above, those old notes
will be credited to an account maintained with DTC for the old notes. This
return or crediting will take place as soon as practicable after withdrawal,
rejection of tender or termination of the exchange offer. You may re-tender

                                        33


properly withdrawn old notes by following one of the procedures described under
"-- Procedures for Tendering Old Notes" at any time on or prior to the
expiration date of the exchange offer.

CONDITIONS TO THE EXCHANGE OFFER

     Despite any other term of the exchange offer, we will not be required to
accept for exchange any old notes and we may terminate or amend the exchange
offer as provided in this prospectus before accepting any old notes for exchange
if in our reasonable judgment:

     - the exchange notes to be received will not be tradable by the holder
       without restriction under the Securities Act and the Exchange Act and
       without material restrictions under the blue sky or securities laws of
       substantially all of the states of the United States;

     - the exchange offer, or the making of any exchange by a holder of old
       notes, would violate applicable law or any applicable interpretation of
       the staff of the SEC; or

     - any action or proceeding has been instituted or threatened in any court
       or by or before any governmental agency with respect to the exchange
       offer that would reasonably be expected to impair our ability to proceed
       with the exchange offer.

     We will not be obligated to accept for exchange the old notes of any holder
that has not made to us:

     - the representations described under the captions "-- Procedures for
       Tendering Old Notes" and "Plan of Distribution;" and

     - any other representations that may be reasonably necessary under
       applicable SEC rules, regulations or interpretations to make available to
       us an appropriate form for registration of the exchange notes under the
       Securities Act.

     We expressly reserve the right, at any time or at various times, to extend
the period of time during which the exchange offer is open. Consequently, we may
delay acceptance of any old notes by giving oral or written notice of an
extension to their holders. During an extension, all old notes previously
tendered will remain subject to the exchange offer, and we may accept them for
exchange. We will return any old notes that we do not accept for exchange for
any reason without expense to their tendering holder as promptly as practicable
after the expiration or termination of the exchange offer.

     We expressly reserve the right to amend or terminate the exchange offer and
to reject for exchange any old notes not previously accepted for exchange, upon
the occurrence of any of the conditions of the exchange offer specified above.
By public announcement we will give oral or written notice of any extension,
amendment, non-acceptance or termination to the holders of the old notes as
promptly as practicable. If we amend the exchange offer in a manner that we
consider material, we will disclose the amendment in the manner required by
applicable law.

     These conditions are solely for our benefit and we may assert them
regardless of the circumstances that may give rise to them or waive them in
whole or in part at any time or at various times in our sole discretion. If we
fail at any time to exercise any of the foregoing rights, this failure will not
constitute a waiver of that right. Each of these rights will be deemed an
ongoing right that we may assert at any time or at various times.

     We will not accept for exchange any old notes tendered, and will not issue
the exchange notes in exchange for any old notes, if at any time a stop order is
threatened or in effect with respect to the registration statement of which this
prospectus constitutes a part or the qualification of the Indenture under the
Trust Indenture Act of 1939.

                                        34


TRANSFER TAXES

     We will pay all transfer taxes, if any, applicable to the transfer and
exchange of old notes pursuant to the exchange offer. The tendering holder,
however, will be required to pay any transfer taxes, whether imposed on the
record holder or any other person, if:

     - delivery of the exchange notes, or certificates for old notes for
       principal amounts not exchanged, are to be made to any person other than
       the record holder of the old notes tendered;

     - tendered certificates for old notes are recorded in the name of any
       person other than the person signing any letter of transmittal; or

     - a transfer tax is imposed for any reason other than the transfer and
       exchange of old notes under the exchange offer.

CONSEQUENCES OF FAILURE TO EXCHANGE

     If you do not exchange your old notes for the exchange notes in the
exchange offer, you will remain subject to restrictions on transfer of the old
notes:

     - as set forth in the legend printed on the old notes as a consequence of
       the issuance of the old notes pursuant to the exemptions from, or in
       transactions not subject to, the registration requirements of the
       Securities Act and applicable state securities laws; and

     - as otherwise set forth in the prospectus distributed in connection with
       the private offering of the old notes.

     In general, you may not offer or sell the old notes unless they are
registered under the Securities Act, or if the offer or sale is exempt from
registration under the Securities Act and applicable state securities laws.
Except as required by the registration rights agreement relating to the old
notes, we do not intend to register resales of the old notes under the
Securities Act. Based on interpretations of the SEC, you may offer for resale,
resell or otherwise transfer the exchange notes issued in the exchange offer
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that:

     - you are not an "affiliate" within the meaning of Rule 405 under the
       Securities Act;

     - you acquired the exchange notes in the ordinary course of your business;
       and

     - you have no arrangement or understanding with respect to the distribution
       of the exchange notes to be acquired in the exchange offer.

     If you tender old notes in the exchange offer for the purpose of
participating in a distribution of the exchange notes:

     - you cannot rely on the applicable interpretations of the SEC; and

     - you must comply with the registration and prospectus delivery
       requirements of the Securities Act in connection with a secondary resale
       transaction and that such a secondary resale transaction must be covered
       by an effective registration statement containing the selling security
       holder information required by Item 507 or 508, as applicable, of
       Regulation S-K under the Securities Act.

OTHER

     Participation in the exchange offer is voluntary, and you should carefully
consider whether to exchange the old notes for the exchange notes. We urge you
to consult your financial and tax advisors in making your own decision on what
action to take.

     We may in the future seek to acquire untendered old notes in open market or
privately negotiated transactions, through subsequent exchange offers or
otherwise, on terms that may differ from the terms of the exchange offer. We
have no present plans to acquire any old notes that are not tendered in the
exchange offer or to file a registration statement to permit resales or any
untendered old notes.

                                USE OF PROCEEDS

     We will not receive any cash proceeds from the issuance of the exchange
notes in the exchange offer. In consideration for issuing the exchange notes as
contemplated by this prospectus, we will receive the old notes in like principal
amount. The old notes surrendered in exchange for the exchange notes will be
retired and cancelled and cannot be reissued. Accordingly, the issuance of the
exchange notes will not result in any increase in our indebtedness or capital
stock.

                                    BUSINESS

OVERVIEW

     We are an independent energy company engaged in oil and natural gas
exploitation, acquisition and exploration activities primarily in the United
States. Our reserves and operations are concentrated in the following divisions:
Western, which includes the Acquired Properties in the Uinta Basin; Northern,
which primarily includes properties in North Dakota and Wyoming; Southern, which
primarily includes properties in Oklahoma, Texas and Louisiana; and Gulf of
Mexico, which includes our offshore properties. We focus on maintaining a
balanced portfolio of lower-risk, long-life onshore reserves and higher-margin
offshore reserves to provide a diversified cash flow foundation for our
exploitation, acquisition and exploration activities.

     On December 17, 2002, effective as of June 1, 2002, we acquired producing
properties, undeveloped leaseholds, gathering and compression facilities and
other related assets in the Greater Natural Buttes area of Uintah County, Utah
from El Paso for approximately $510 million, including purchase price
adjustments, pursuant to the Purchase and Sale Agreement, dated November 6,
2002, as amended. We used the net proceeds from our shelf offering and debt
offering to fund the purchase price.

     Over the last several years acquisitions and subsequent exploitation
activities focused in core project areas have fueled growth in our reserves,
production and cash flow. From year-end 1997 to September 30, 2002, we increased
proved reserves from 197 Bcfe to 1,662 Bcfe, a compounded annual growth rate of
approximately 53%. Over the same period we increased average daily production
from 66 Mmcfe/d to 417 Mmcfe/d, a compounded annual growth rate of approximately
45%. This growth has been complemented by consistent reductions in our per unit
cost structure over the same period from $1.32 per Mcfe to $1.05 per Mcfe of our
net production for lease operating expenses, transportation costs, production
taxes and general and administrative costs. For the 12 months ended September
30, 2002, we generated net revenues and EBITDAX of $437 million and $296
million, respectively.

     We believe that our sizable exploration inventory and our exploitation and
acquisition expertise, together with our operating experience and efficient cost
structure, provide us with the ability to generate substantial current cash flow
and position us for future growth. We operate approximately 79% of the net
present value of our reserves, allowing us to better manage expenses, capital
allocation and the decision-making processes related to all aspects of
exploitation and exploration activities. We have a capital budget of
approximately $170 million for 2002, which does not include acquisitions. Nearly
65% of the 2002 budget is allocated to exploitation, which includes lower-risk
drilling and continued expansion of our secondary recovery projects. We expect
that our total 2003 capital budget, excluding acquisitions, will be $230
million, 75% of which has been allocated to exploitation. We have approximately
2,300 identified exploitation opportunities and anticipate drilling 300 to 350
of these locations during 2003.

     As of September 30, 2002, our estimated proved reserves of 1,662 Bcfe had a
pre-tax net present value, discounted at 10%, of approximately $2.3 billion
based on period-end NYMEX prices of $30.45 per barrel of oil and $4.14 per Mmbtu
of natural gas. Approximately 66% of our reserves was classified as proved
developed as of September 30, 2002.

(3) As of September 30, 2002, the properties acquired in our Southeast Texas
    Acquisition, which are not included in the third quarter production for the
    Southern Division above, were producing approximately 28 Mmcfe/d.

  WESTERN DIVISION

     On December 17, 2002, effective as of June 1, 2002, we acquired producing
properties, undeveloped leaseholds, gathering and compression facilities and
other related assets in the Greater Natural Buttes area of Uintah County, Utah
from El Paso for approximately $510 million, including purchase price
adjustments, pursuant to the Purchase and Sale Agreement, dated November 6,
2002, as amended. We used the net proceeds from our December 16, 2002 shelf
offering and December 17, 2002 debt offering to fund the purchase price. This
division represented 19% of our net present value of estimated proved reserves
as of September 30, 2002, and contributed 19% of our pro forma third quarter
2002 production. We have interests in 1,110 gross (approximately 872 net)
producing wells.

     The Acquisition establishes a new core area and has the following
attributes:

     - increases our proved reserves by approximately 57%, or 603 Bcfe,
       replacing approximately 465% of our estimated 2002 production and giving
       us nearly 1 Tcfe of proved reserves in the Rocky Mountains;

     - raises current production in excess of 20%, to approximately 417 Mmcfe/d,
       placing us among the top 20 largest domestic independent exploration and
       production companies based on third quarter 2002 daily production;

     - adds long-life, operated gas properties with a reserves to production
       ratio of 21 years, extending our overall reserve life index from
       approximately seven years to approximately 11 years and increasing the
       gas portion of both our proved reserves and production to 68%;

     - contains upside potential with over 600 proved undeveloped locations and
       approximately 900 additional drilling opportunities;

     - provides exploration opportunities on over 240,000 net acres of
       leasehold, including targets outside the producing areas and deeper
       formations within the producing areas; and

     - allows us to control the gathering and marketing of our natural gas from
       the Acquired Properties and affords us access to interstate pipelines
       flowing east, such as Colorado Interstate Gas, and west, such as Kern
       River.

                                        39


     Since entering into the Purchase and Sale Agreement, we have secured firm
transportation averaging at least 107 Mmbtu/d for 2003 and increasing annually
over the next three years thereafter, hedged 98% of expected 2003
Acquisition-related production at floor and ceiling prices averaging $3.81 to
$3.99 per Mmbtu, respectively, and 63% of estimated 2004 Acquisition-related
production at floor and ceiling prices of $3.76 to $3.87 per Mmbtu,
respectively. Additionally, we have hedged basis differentials for approximately
65% of anticipated 2003 Acquisition-related production and 50% of anticipated
2004 Acquisition-related production.

     In the Greater Natural Buttes area, we will operate 740 net wells, or
approximately 92% of our proved reserve value in the area. Through our high
working interest and level of operations we can control the majority of
drilling, completion and production of wells.

     The Greater Natural Buttes field is a legacy asset. Natural gas was first
discovered in the field in 1955. Since that time, more than 900 Bcf of natural
gas has been produced. Since 1991, development accelerated with more than 1,000
wells drilled in the field, approximately 98% of which were successful. The
properties are characterized by established production profiles and long reserve
lives. Producing horizons range from 5,000 to 14,000 feet, with production
coming primarily from the Wasatch and Upper Mesa Verde formations.

     The field has undergone a series of downspacings from the original spacing
of 320 acres per well to current spacing of 40 acres per well. In adjacent
units, operators are currently downspacing to 20 acres per well, which could
yield as many as 1,400 locations on our acreage in addition to our 1,500
identified exploitation locations. Operators of adjacent units have also drilled
successful gas wells to the Lower Mesa Verde and Mancos formations underlying
the primary field production, which could be prospective on our acreage. In
addition to 205,000 net developed acres, we will also hold 35,000 net
undeveloped acres surrounding the Greater Natural Buttes area which we believe
are prospective for future development.

     We expect to drill 80 to 90 wells in 2003 and plan to expand the program to
120 to 150 wells per year for the next three to four years thereafter.

  NORTHERN DIVISION

     The Northern Division conducts operations in the Rocky Mountain region
which includes the Williston, Powder River, Big Horn and Green River Basins. The
Division represented 22% of our net present value of estimated proved reserves
as of September 30, 2002, and contributed 27% of our third quarter 2002 net
production. We have interests in 560,262 developed and 1,142,519 undeveloped
gross acres in the region and in 2,102 gross (approximately 872 net) producing
wells.

     Our strategy in the Northern Division is to exploit lower-risk infill,
horizontal and secondary/tertiary recovery opportunities on existing properties,
pursue gas-weighted exploration opportunities and make tactical acquisitions to
enhance current operations.

     On March 1, 2002, we completed the purchase of producing oil and gas
properties located in the Williston Basin in North Dakota and Montana for
approximately $39 million. We estimate the total proved reserves for these
properties as of the acquisition date to be approximately 54 Bcfe, of which
approximately 90% is oil. We operate over 70% of these properties, which have an
average lifting cost of $5.82 per bbl. Our net production from these properties
for the third quarter 2002 was approximately 1,650 bbl/d.

     Williston Basin.  Our activity in the Williston Basin continues to focus on
horizontal field extensions, field deepenings to new horizons and growth of our
secondary recovery projects. We continued our development program by re-entering
existing wells for horizontal extensions in five fields. We are currently
completing three horizontal wells and two deepenings. Our most active project
continues to be the Wiley field.

     - Wiley Field.  We operate this waterflood with a 54% working interest. In
       2000, we initiated a horizontal drilling program and through September
       30, 2002 have drilled 37 wells, all of which were successful. In addition
       to the horizontal drilling, we increased water injection capacity to
       expand our waterflood program. As a result of this activity, gross daily
       production has increased from approximately 600 bbl/d in April 2000 to
       over 3,300 bbl/d at the end of the third quarter 2002. Over the next

                                        40


       12 months, we plan to drill 10 to 15 additional wells in this area while
       continuing to increase water injection capacity.

     Greater Green River Basin.  In the Greater Green River Basin we have over
400,000 gross undeveloped acres. Over the next 12 to 24 months we expect to
drill seven to 10 exploration wells. One of the primary operating areas within
the basin is the Moxa Arch Complex. This area represents a multi-year program
where we have identified more than 100 potential drilling locations on our
acreage. Wells target the Frontier and Dakota formations at depths that range
from 10,000 to 12,500 feet. Production from Moxa Arch wells, particularly from
the Frontier formation, tends to be long-lived, with 25 to 30 year reserve life
potential.

     Powder River Basin.  In the Powder River Basin, we currently have
approximately 54,000 gross undeveloped acres, which we believe are prospective
for coalbed methane drilling. From the beginning of 2000 through September 30,
2002, we participated in the drilling of 265 wells, 262 of which were
successful. We operate 137 of these wells. In 2003, we expect to participate in
another 130 to 160 wells.

     Big Horn Basin.  The Gooseberry field is our most significant property in
the Big Horn Basin. We own a 100% working interest (nearly 90% net revenue
interest) in this field, which consists of two waterflood units. Since acquiring
the field in February 1995, we have more than doubled the production from
approximately 535 bbl/d to over 1,150 bbl/d in September 2002. This has been
accomplished through the acquisition of proprietary 3-D seismic data, drilling
of delineation wells, installation of the two waterfloods and the addition of
shallower producing zones. In 2002, we placed a larger pipeline in service to
accommodate the increasing production from the unit. During the next 12 months,
we plan to drill two to three additional wells and to expand water injection
capacity. We currently have over 200,000 gross undeveloped acres in the Big Horn
Basin.

  SOUTHERN DIVISION

     The Southern Division conducts operations in the Permian Basin, onshore
Gulf Coast and Mid-Continent regions. This division represented 38% of the net
present value of our estimated proved reserves as of September 30, 2002, and
contributed 29% of our third quarter 2002 net production. We have interests in
542,093 developed and 95,738 undeveloped gross acres and in 3,530 gross
(approximately 1,475 net) producing wells.

     Permian Basin.  The Southern Division's principal Permian Basin properties
are the Andrews Unit, Howard Glasscock Field and the Shafter Lake San Andres
Unit.

     - Andrews Unit.  The Andrews Unit produces from the Wolfcamp/Penn formation
       at approximately 8,600 feet. We have a 98.6% working interest in this
       3,230-acre unit. Water injection began in late 1996 with the first
       response occurring in late 1998. During 2000 and 2001, we expanded the
       waterflood program by drilling additional wells, converting wells to
       injectors and performing workovers on existing wells. As a result,
       production continues to increase from an 855 bbl/d average in 2000 to
       1,115 bbl/d as of September 30, 2002. We drilled two wells and converted
       two wells to injectors in the nine months ended September 30, 2002, and
       expect to drill two wells in the fourth quarter 2002. We believe that
       production from this waterflood unit can be further enhanced with the use
       of CO(2) flooding or other tertiary recovery methods.

     - Howard Glasscock Field.  We continue to exploit our 100% working interest
       in the Howard Glasscock Field. Based on the results from adjacent
       successful waterfloods, we believe that additional potential exists
       through the installation of new and expansion of existing waterfloods on
       our leases. In May 2001, we initiated a drilling program for 27 injection
       and development wells to expand waterfloods on two of our leases. Water
       injection commenced in first quarter 2002. Production has increased from
       approximately 1,090 bbl/d at December 31, 2000 to approximately 1,530
       bbl/d as of September 30, 2002. Additionally, we have identified a number
       of opportunities for recompletion and well deepenings.

     - Shafter Lake San Andres Unit.  The Shafter Lake San Andres Unit is a
       12,880-acre unit that produces from the Grayburg and San Andres
       formations at a depth of approximately 4,500 feet. We have an 81.4%
       working interest in this secondary recovery unit. During the nine months
       ended
                                        41


       September 30, 2002, we drilled eight wells on 10-acre spacing and plan to
       drill 10 to 15 additional 10-acre wells in 2003. The unit was producing
       700 bbl/d as of September 30, 2002. Operators of nearby San Andres fields
       have successfully drilled to 10-acre spacing before CO(2) injection. We
       believe the potential exists for CO(2) flooding as the field matures.

     Onshore Gulf Coast.  The Southern Division's Gulf Coast operations are
primarily focused in the Yegua trend of southeast Texas, in the Austin
Chalk/Georgetown trend of east-central Texas, and in Northern Louisiana where we
are active in two fields, the Elm Grove Field and the North Louisiana Field
Complex.

     - Southeast Texas Properties.  We acquired these oil and gas properties on
       September 30, 2002. The total estimated proved reserves are approximately
       76 Bcfe, of which 82% is natural gas. We operate essentially all of these
       properties. We also acquired approximately 10,000 net undeveloped acres
       and an interest in 120 square miles of 3-D seismic data. We are currently
       shooting an additional 180 square miles of 3-D seismic data. The
       properties are primarily located in Liberty, Hardin and Jasper counties
       in the Gulf Coast region of southeast Texas. As of September 30, 2002,
       these properties produced approximately 28 Mmcfe/d net to the acquired
       interests. Since closing the transaction, we completed an exploration
       well which flow tested 4 Mmcf/d and 500 bbl/d, and drilled a development
       well which was recently completed. Both wells are expected to be
       connected to the sales pipeline by mid-December 2002. Currently, we have
       one rig drilling in the area and expect to drill 15 exploration prospects
       over the next 12 to 24 months.

     - Austin Chalk/Georgetown Trend.  The trend is a fractured carbonate
       formation that has been highly conducive to the application of horizontal
       drilling technology. The Austin Chalk formation is encountered in this
       field at depths ranging between 7,000 and 17,000 feet. The Georgetown
       formation, approximately 300 to 500 feet below the base of the Austin
       Chalk, has been a secondary objective in the field. We control
       approximately 50,000 gross (13,000 net) undeveloped acres and 114,000
       gross (43,000 net) developed acres in this area. In 2001, we participated
       in the drilling of five Georgetown wells and one Austin Chalk well, all
       of which were successful. In the first nine months of 2002, we drilled
       three wells, all of which were successful. In the fourth quarter 2002, we
       plan to re-enter one well to drill the Georgetown horizontal section.

     - Elm Grove Field.  This field was drilled to extend the Cotton Valley
       production downdip from the mature Caspiana field. In addition to the
       Cotton Valley, shallower secondary objectives include the Hosston and
       Rodessa intervals. We own an approximate 37% working interest in the
       field. In 2001, a total of 42 wells were drilled, all of which were
       successful. Gross production in the field has increased from 34 Mmcfe/d
       in January 2001, to 61 Mmcfe/d in September 2002. In the nine months
       ended September 30, 2002, we drilled 23 wells, all of which were
       successful, and plan to drill an additional six to eight wells in the
       fourth quarter 2002. In 2003, we plan to drill 20 to 25 additional wells
       in this field.

     - North Louisiana Field Complex.  We acquired this interest in late 1998
       and have identified over 100 development locations in its four
       fields -- Ada, Sibley, West Bryceland and Sailes. The 2,000 foot thick
       Hosston interval contains over 20 separate producing zones. In 2001, we
       drilled 34 wells, all of which were successful. In the nine months ended
       September 30, 2002, we drilled 14 wells, 13 of which were successful. We
       anticipate drilling between 15 and 25 wells in this region in each of the
       next two years.

     Mid-Continent.  The Southern Division's Mid-Continent operations are
currently focused in Oklahoma and Kansas. Oil production is concentrated in our
operated waterfloods in Oklahoma, while natural gas production is primarily in
third party operated wells in Oklahoma and in our operated wells in Kansas. The
most significant waterflood unit in Oklahoma is the Calumet Cottage Grove Unit.
We operate this secondary recovery unit consisting of 11,400 acres in central
Oklahoma. Production is from the Pennsylvanian Cottage Grove formation at 8,100
feet. We have a 44.1% working interest in this unit. In 2001, a total of seven
wells were drilled, all of which were successful. We drilled four additional
successful wells in the nine months ended September 30, 2002, and plan to drill
one well in the fourth quarter 2002. The Calumet Unit was producing 1,350 bbl/d
as of September 30, 2002.

                                        42


  GULF OF MEXICO DIVISION

     The Gulf of Mexico Division represented 21% of the net present value of our
estimated proved reserves as of September 30, 2002, and contributed 26% of our
third quarter 2002 net production. As of September 30, 2002, we have interests
in 329,989 developed and 299,260 undeveloped gross acres in the Gulf of Mexico
and in 200 gross (approximately 51 net) producing wells.

     In addition to a production base with numerous exploitation opportunities
within our developed acreage, the Gulf of Mexico provides us with moderate-risk
exploration targets. We drilled 16 exploration wells in the Gulf of Mexico in
2001, 11 of which were successful, and eight exploration wells in the first nine
months of 2002, three of which were successful. We expect to drill five
additional exploration tests in the fourth quarter 2002. We have under license
3-D seismic data covering over 18,000 square miles (approximately 2,300 blocks)
and 2-D seismic data covering 150,000 linear miles within the Gulf of Mexico.

     West Cameron Blocks 180/198.  The West Cameron Blocks 180/198 complex
consists of all or a portion of seven offshore blocks, including 30,000 gross
developed and 5,000 gross undeveloped acres. The complex is located 30 miles
offshore in 52 feet of water. It has produced approximately 1.7 Tcf of natural
gas and 10 Mmbbl of oil from over 20 separate producing zones since its
discovery. Since acquiring this field in October 1997, we have increased gross
production from approximately 26 Mmcfe/d to a peak rate of 63 Mmcfe/d in
mid-2001. At September 30, 2002, the field was producing 50 Mmcfe/d (37 Mmcfe/d
net).

     A successful development well was drilled in late 2002, and we initiated
drilling of an offset well, which will be completed by the end of the year.
Several recompletions were also done in 2002. We believe that this complex holds
additional drilling opportunities.

     High Island Block 197.  This field is located approximately 28 miles
offshore in 50 feet of water and was discovered in the third quarter of 2001. We
have a 25% non-operated working interest in the field. A second well was drilled
in 2001. In the first quarter of 2002, we farmed into an adjoining block, where
an exploration well was drilled. The field came on production in May 2002, at a
gross rate of 44 Mmcfe/d from one well. Two other development wells were drilled
in 2002, and by September 2002, four wells were producing 120 Mmcfe/d (21.5
Mmcfe/d net).

     High Island Block 84.  This field is located approximately 23 miles
offshore in 50 feet of water and was discovered in the third quarter of 2001,
with three development wells being drilled in 2002. We operate the field.
Production commenced in June 2002 from two wells at a gross rate of 32 Mmcfe/d
(13.5 Mmcfe/d net). The two remaining wells are expected to commence production
in 2003.

     Vermilion Block 408.  This field is located approximately 110 miles
offshore in 400 feet of water and was discovered in 1999. We have a 25%
non-operated working interest in the field. Facilities were installed in late
2001 and production commenced in the first quarter of 2002. At September 30,
2002, the wells were producing 42 Mmcfe/d (8.5 Mmcfe/d net).

     West Cameron Blocks 613/614.  We discovered this field in 1997. It is
located approximately 120 miles offshore in 290 feet of water. We drilled a
second successful exploration well on an adjoining block in the third quarter of
2000. We operate the field with a working interest of 50% and installed
facilities and commenced production in December 2000. At September 30, 2002, the
wells were producing 20 Mmcfe/d (7 Mmcfe/d net).

     East Cameron Block 369.  We discovered this field in the first quarter of
2001 and commenced production from it in December 2001. It is located
approximately 132 miles offshore in 350 feet of water. We operate the two-well
field with a 60% working interest. At September 30, 2002, the wells were
producing approximately 14 Mmcfe/d (6.5 Mmcfe/d net).

  RECENT DISCOVERIES

     - South Timbalier 316.  We discovered this field located approximately 66
       miles offshore in 400 feet of water in the fourth quarter of 2001. We
       operate the field with a 40% working interest. Three wells have

                                        43


       been drilled. We expect to install a platform and commence production in
       the second half of 2003. Facility capacity on the platform will be 150
       Mmcfe/d (47 Mmcfe/d net).

     - Galveston 352.  A successful exploratory well was drilled in the spring
       of 2002 and put on production in August. We operate the well with a 67%
       working interest. It is currently producing from a small zone below the
       main reservoir at a gross rate of 4 Mmcfe/d (2.1 Mmcfe/d net).

     - Green Canyon 640.  We have a 3.5% overriding royalty interest in a
       discovery drilled by ChevronTexaco named Tahiti. Delineation drilling and
       evaluation is ongoing.

     Estimated quantities of our oil and natural gas reserves and the present
value of such reserves as of September 30, 2002, are based upon reserve reports
prepared by our engineering staff. At December 31, 2001, Ryder Scott Company,
L.P. audited 87% of the total net present value of estimates of total proved
reserves and the remaining 13% of net present value of the reserves was
unaudited. Estimates of total proved reserves at December 31, 2000, were
prepared by Ryder Scott and Netherland, Sewell and Associates, Inc. and our
engineering staff. The Ryder Scott and Netherland Sewell reports covered
approximately 85% of the total net present value of the reserves and the
internally generated report covered the remaining 15% of the net present value.
Estimated quantities of oil and natural gas reserves of the Acquired Properties
and the net present value of these reserves as of December 30, 2000, December
31, 2001 and September 30, 2002, are based upon a reserve report prepared by our
engineering staff, with the September 30, 2002 reserve report having been
audited by the independent engineering firm of Ryder Scott Company, L.P.

     Proved developed reserves are proved reserves that are expected to be
recovered from existing wells with existing equipment and operating methods.
Proved undeveloped reserves are proved reserves that are expected to be
recovered from new wells drilled to known reservoirs on undrilled acreage for
which the existence and recoverability of such reserves can be estimated with
reasonable certainty, or from existing wells where a relatively major
expenditure is required to establish production.

     There are numerous uncertainties inherent in estimating quantities of
proved reserves and in projecting future rates of production and timing of
exploitation expenditures. The data in the above tables represent estimates
only. Oil and natural gas reserve engineering is inherently a subjective process
of estimating underground accumulations of oil and natural gas that cannot be
measured exactly, and estimates of other engineers might differ materially from
those shown above. The accuracy of any reserve estimate is a function of the
quality of available data and engineering and geological interpretation and
judgment. Results of drilling, testing and production after the date of the
estimate may justify revisions. Accordingly, reserve estimates may vary from the
quantities of oil and natural gas that are ultimately recovered.

     Future prices received for production and costs may vary, perhaps
significantly, from the prices and costs assumed for purposes of these
estimates. The present value shown should not be construed as the current market
value of the reserves. The 10% discount factor used to calculate present value,
which is mandated by generally accepted accounting principles, is not
necessarily the most appropriate discount rate. The present value, no matter
what discount rate is used, is materially affected by assumptions as to timing
of future production, which may prove to be inaccurate. For properties that we
operate, expenses exclude our share of overhead charges. In addition, the
calculation of estimated future net revenues does not take into account the
effect of various cash outlays, including, among other things, general and
administrative costs and interest expense.

DRILLING RESULTS

     The following table sets forth information with respect to wells drilled
during the periods indicated. The information should not be considered
indicative of future performance, nor should it be assumed that there is
necessarily any correlation between the number of productive wells drilled,
quantities of reserves found or economic value. Productive wells are those that
produce commercial quantities of hydrocarbons, whether or not they produce a
reasonable rate of return.

LIQUIDITY AND CAPITAL RESOURCES

     Our principal uses of capital have been for the exploitation, acquisition
and exploration of oil and natural gas properties.

     Net cash provided by operating activities was $159.8 million for the nine
months ended September 30, 2002 compared to $175.7 million for the nine months
ended September 30, 2001. Operating cash flow in the nine month period decreased
compared to the prior period due to decreased oil and natural gas prices, and
higher operating and other expenses.

     Net cash used in investing activities was $263.0 million for the nine
months ended September 30, 2002 compared to $138.4 million for the nine months
ended September 30, 2001. Of this total for the nine months ended September 30,
2002, $104.9 million was used for exploitation and exploration activities and
$168.5 million was used for acquisitions, offset by proceeds from sales of
properties of $10.5 million. Investing activities for the nine months ended
September 30, 2001 included $132.7 million for exploitation and exploration
activities and $6.3 million for acquisitions, offset by proceeds from sales of
properties of $0.7 million.

     Net cash provided by (used in) financing activities was $110.8 million for
the nine months ended September 30, 2002 compared to ($20.5) million for the
nine months ended September 30, 2001. Financing activities for the nine months
ended September 30, 2002 consisted of $155.0 million in borrowings utilized for
the acquisition and development of oil and natural gas properties, $1.1 million
from issuance of common stock and $3.7 million from the gain on the cancellation
of the 8 7/8% fair value interest rate swap offset by $45.0 million debt
repayment and a $3.6 million preferred stock dividend payment.

FINANCING ACTIVITY

  REPLACEMENT CREDIT FACILITY

     On December 17, 2002, we entered into the Replacement Credit Facility to
replace our previous revolving credit facility. The Replacement Credit Facility
provides for a maximum committed amount of $600 million and an initial borrowing
base of approximately $470 million. The facility matures on December 16, 2006
and contains covenants and default provisions customary for similar credit
facilities. We made borrowings under the Replacement Credit Facility to
refinance all outstanding indebtedness under our previous revolving credit
facility and to pay general corporate expenses.

     Advances under the Replacement Credit Facility are in the form of either an
ABR loan or a Eurodollar loan. The interest on an ABR loan is a fluctuating rate
based upon the highest of: (1) the rate of interest announced by JPMorgan Chase
Bank as its prime rate; (2) the secondary market rate for three-month
certificates of deposits plus 1%; and (3) the Federal funds effective rate plus
0.5%, plus in each case a margin of 0% to 0.625% based upon the ratio of total
debt to EBITDAX and the ratings of our senior unsecured debt as issued by
Standard and Poor's Rating Group and Moody's Investors Service, Inc. EBITDAX is
defined as net income plus interest expense, income tax expense, and amounts
attributable to depreciation, depletion, exploration, amortization and other
non-cash charges and expenses, but excluding changes in value of certain hedging
instruments and extraordinary or nonrecurring gains or losses, subject to
certain other specified adjustments. The interest on a Eurodollar loan is a
fluctuating rate based upon the rate at which Eurodollar deposits in the London
interbank market are quoted plus a margin of 1.000% to 1.875% based upon the
ratio of total debt to EBITDAX and the ratings of our senior unsecured debt as
issued by Standard and Poor's Rating Group and Moody's Investors Service, Inc.

     As of January 15, 2003, we had borrowings and letters of credit issued of
approximately $111 million outstanding under the Replacement Credit Facility,
with a weighted average interest rate of 3.3% and available unused borrowing
capacity of approximately $359 million.

  8 1/4% SENIOR SUBORDINATED NOTES DUE 2011

     On December 17, 2002, we issued $300 million in additional principal amount
of our 8 1/4% Senior Subordinated Notes Due 2011, or the old notes, pursuant to
Rule 144A under the Securities Act at a price of

                                        48


103% of the principal amount, with accrued interest from November 1, 2002. The
old notes are additional debt securities under the Indenture pursuant to which,
on November 5, 2001, we issued $275 million of our 8 1/4% Senior Subordinated
Notes Due 2011. On March 14, 2002, all of the 2001 notes were exchanged in an
exchange offer for an equal principal amount of the initial exchange notes. We
used the proceeds from the sale of the old notes to finance, in part, the
Acquisition. We have agreed to file this exchange offer registration statement
or, under certain circumstances, a shelf registration statement pursuant to a
registration rights agreement relating to the old notes. In the event we fail to
comply with some of our obligations under the registration rights agreement
relating to the old notes, we will pay additional interest on the old notes. We
are currently offering to exchange up to $300 million aggregate principal amount
of new 8 1/4% Senior Subordinated Notes Due 2011, or exchange notes, that have
been registered under the Securities Act for an equal principal amount of old
notes.

     The notes are senior subordinated unsecured obligations of Westport and are
fully and unconditionally guaranteed on a senior subordinated basis by some of
our existing and future restricted subsidiaries. The notes mature on November 1,
2011. We pay interest on the notes semiannually on May 1 and November 1. Our
first interest payment on the old notes will be May 1, 2003. We are entitled to
redeem the notes in whole or in part on or after November 1, 2006 for the
redemption price set forth in the notes. Prior to November 1, 2006, we are
entitled to redeem the notes, in whole but not in part, at a redemption price
equal to the principal amount of the notes plus a premium. There is no sinking
fund for the notes. If we fail to comply with some of our obligations under the
registration rights agreement relating to the old notes, we will pay additional
interest on the old notes.

  8 7/8% SENIOR SUBORDINATED NOTES DUE 2007

     In connection with our merger with and into Belco Oil & Gas Corp., or
Belco, we assumed $147 million face amount of Belco's 8 7/8% Senior Subordinated
Notes Due 2007. On November 1, 2001, approximately $24.3 million face amount of
the Belco notes was tendered to us pursuant to the change of control provisions
of the related indenture. The tender price was equal to 101% of the principal
amount of each note plus accrued and unpaid interest as of October 29, 2001.
Including the premium and accrued interest, the total amount paid was $24.8
million. We used borrowings under our previous revolving credit facility to fund
the repayment. No gain or loss was recorded in connection with the redemption as
the fair value of the 8 7/8% Senior Subordinated Notes recorded in connection
with the merger equaled the redemption cost.

  THE PRIVATE EQUITY OFFERING

     On November 19, 2002, we completed the private equity offering of 3.125
million shares of our common stock to Spindrift Partners, L.P., Spindrift
Investors (Bermuda) L.P., Global Natural Resources III and Global Natural
Resources III L.P. at a net price to us of $16.00 per share for aggregate
proceeds of $50 million. The purchasers may not sell this common stock until 90
days after the closing of the private equity offering and may be prohibited from
selling this common stock at our option for up to 187 days in the event we
pursue a public equity offering during the next two years. The terms of the sale
were negotiated on November 11, 2002 and the net price represents a 9% discount
from the closing price of our common stock on the New York Stock Exchange as of
that date.

     In connection with the private equity offering, we agreed to file a shelf
registration statement registering the resale by the selling stockholders from
time to time of the common stock we issued in the private equity offering. We
also agreed to use our reasonable best efforts to cause the registration
statement to become effective within 90 days of the closing of the private
equity offering. In addition, we agreed, subject to certain rights of
suspension, to keep such registration statement effective until the earlier of
(1) the date on which all of the shares have been (a) sold under the
registration statement or (b) distributed pursuant to Rule 144(k) under the
Securities Act or (2) two years after the date of the stock purchase agreement.
On December 31, 2002, we filed the shelf registration statement registering the
resale by the selling stockholders from time to time of our common stock issued
in the private equity offering, which registration statement the SEC declared
effective on January 7, 2003

                                        49


  SHELF OFFERING

     On December 16, 2002, we closed the shelf offering of 11.5 million shares
of common stock at a price of $19.90 per share, which includes 1.5 million
shares covered by an over-allotment option we granted to, and which was
exercised by, the underwriters. We received net proceeds of approximately $216
million from the sale of our common stock, which we used to finance, in part,
the Acquisition.

  FUTURE CAPITAL NEEDS AND RESOURCES

     We expect that our capital expenditure budget, excluding acquisitions, for
2003 will be approximately $230 million. Our capital expenditures excluding
acquisitions for 2002 were approximately $163 million and our primary cash
requirements for 2002 included funding acquisitions, funding development
projects and general working capital needs. For the first nine months of 2002,
we had capital expenditures of $104.9 million excluding geological and
geophysical costs incurred of $7 million and excluding acquisition costs
incurred of $168.5 million. We will continue to seek opportunities for
acquisitions of proved reserves with substantial exploitation and exploration
potential. The size and timing of capital requirements for acquisitions is
inherently unpredictable and we therefore do not budget for them. We expect to
fund our capital expenditure activities, which include acquisition, development
of and exploration on our oil and natural gas properties through cash flow from
operations and available capacity under the Replacement Credit Facility.

     We believe that borrowings under the Replacement Credit Facility, projected
operating cash flows and cash on hand will be sufficient to meet the
requirements of our business. However, future cash flows are subject to a number
of variables including the level of production and oil and natural gas prices.
We cannot assure you that operations and other capital resources will provide
cash in sufficient amounts to maintain planned levels of capital expenditures or
that increased capital expenditures will not be undertaken. Actual levels of
capital expenditures may vary significantly due to a variety of factors,
including but not limited to:

     - drilling results;

     - product prices;

     - industry conditions and outlook; and

     - future acquisition of properties.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

  COMMODITY PRICE RISK

     We produce and sell crude oil, natural gas and natural gas liquids.
Accordingly, our operating results may be significantly affected by fluctuations
in commodity prices caused by changing market conditions. We periodically seek
to reduce our exposure to price volatility by hedging our production through
swaps, options and other commodity derivative instruments. We use hedge
accounting for these instruments that qualify under the provisions of SFAS 133,
and settlements of gains or losses on these contracts will be reported as a
component of oil and natural gas revenues and operating cash flows in the
periods realized.

     For the nine months ended September 30, 2002, we recorded hedge settlement
income of approximately $1.5 million, non-hedge settlement income of
approximately $0.8 million and non-hedge change in fair value of derivatives
loss of approximately $8.9 million. For the corresponding period in 2001, we
recorded hedge settlement loss of approximately $1.8 million, non-hedge
settlement loss of approximately $0.6 million and non-hedge change in fair value
of derivatives income of approximately $24.5 million.

     As of November 29, 2002, we had approximately 0.9 Mmbbl of oil, and 3.5 Bcf
of natural gas subject to commodity price risk management contracts for the
fourth quarter of 2002. These contracts are subject to weighted average floor
prices of $22.78 per barrel and $2.85 per Mmbtu and weighted average ceiling
prices of $25.41 per barrel and $3.11 per Mmbtu, respectively.

     Subsequent to the execution of the Purchase and Sale Agreement, we entered
into commodity price risk management contracts for natural gas pursuant to which
we have hedged approximately 31.7 Bcf of 2003
                                        50


natural gas production with a weighted average floor and ceiling prices of $3.81
and $3.99 per Mmbtu, respectively. In addition, 24.4 Bcf of those contracts
correlates to basis hedges with a weighted average price differential of $0.72
per Mmbtu. Subsequent to the execution of the Purchase and Sale Agreement, we
also hedged approximately 25.6 Bcf of 2004 natural gas production with a
weighted average floor and ceiling prices of $3.76 and $3.87 per Mmbtu,
respectively. In addition, 12.8 Bcf of the 2004 contracts correlates to basis
hedges with a weighted average price differential of $0.66 per Mmbtu.

     The summary tables below provide details about the volumes and prices of
all CPRM, hedge and non-hedge commitments, executed prior to November 29, 2002
with settlements in the following periods.

(1) For any particular swap sold transaction, the counterparty is required to
    make a payment to us in the event that the NYMEX reference price for any
    settlement period is less than the swap price for such

                                        51


hedge, and we are required to make a payment to the counterparty in the event
that the NYMEX reference price for any settlement period is greater than the
swap price for such hedge.

(2) For any particular collar transaction, the counterparty is required to make
    a payment to us if the average NYMEX reference price for the reference
    period is below the floor price for such transaction, and we are required to
    make payment to the counterparty if the average NYMEX reference price is
    above the ceiling price of such transaction.

(3) Calls or puts are sold under written option contracts in return for a
    premium received by us upon the initiation of the contract. We are required
    to make a payment to the counterparty in the event that the NYMEX reference
    price for any settlement period is greater than the price of the call sold,
    or less than the price of the put sold. Conversely, calls or puts bought in
    return for our payment of a premium require the counterparty to make a
    payment to us in the event that the NYMEX reference price on any settlement
    period is greater than the call price or less than the put price.

(4) Three-way collars are settled as described in footnote (2) above, with the
    following exception: if the NYMEX reference price falls below the three-way
    floor price, the average floor price is adjusted by the amount by which the
    NYMEX reference price is below the three-way floor price. For example, on a
    three-way oil collar, if the NYMEX reference price is $18.00 per bbl during
    the term of the 2002 three-way collars, then the average floor price would
    be $22.17 per bbl.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     In October 2001, we entered into a letter agreement with Dominick J. Golio
whereby Mr. Golio would, after cessation of his employment, continue to assist
us in certain pending litigation. As compensation, we agreed to pay Mr. Golio
7 1/2% of our total net recovery, if any, in the litigation. In connection with
the settlement of this litigation in September 2002, we entered into a letter
agreement in December 2002 with Mr. Golio pursuant to which we agreed to pay Mr.
Golio a total of $215,269 in the form of a cash payment of $156,334 and certain
severance benefits with an aggregate value of $58,935, in full satisfaction of
our obligations under the October 2001 letter agreement. Contemporaneously with
the execution of the December 2002 letter agreement, we paid Mr. Golio $156,334,
and will pay the balance owed as it becomes due and payable under the terms of
this letter agreement.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS

REPLACEMENT CREDIT FACILITY

     On December 17, 2002, we entered into the Replacement Credit Facility to
replace our previous revolving credit facility. The Replacement Credit Facility
provides for a maximum committed amount of $600 million and an initial borrowing
base of approximately $470 million. The facility matures on December 16, 2006
and contains covenants and default provisions customary for similar credit
facilities. We made borrowings under the Replacement Credit Facility to
refinance all outstanding indebtedness under our previous revolving credit
facility and to pay general corporate expenses.

     Advances under the Replacement Credit Facility are in the form of either an
ABR loan or a Eurodollar loan. The interest on an ABR loan is a fluctuating rate
based upon the highest of: (1) the rate of interest announced by JPMorgan Chase
Bank as its prime rate; (2) the secondary market rate for three-month
certificates of deposits plus 1%; and (3) the Federal funds effective rate plus
0.5%, plus in each case a margin of 0% to 0.625% based upon the ratio of total
debt to EBITDAX and the ratings of our senior unsecured debt as issued by
Standard and Poor's Rating Group and Moody's Investors Service, Inc. EBITDAX is
defined as net income plus interest expense, income tax expense, and amounts
attributable to depreciation, depletion, exploration, amortization and other
non-cash charges and expenses, but excluding changes in value of certain hedging
instruments and extraordinary or nonrecurring gains or losses, subject to
certain other specified adjustments. The interest on a Eurodollar loan is a
fluctuating rate based upon the rate at which Eurodollar deposits in the London
interbank market are quoted plus a margin of 1.000% to 1.875% based upon the
ratio of total debt to EBITDAX and the ratings of our senior unsecured debt as
issued by Standard and Poor's Rating Group and Moody's Investors Service, Inc.

     As of January 15, 2003, we had borrowings and letters of credit issued of
approximately $111 million outstanding under the Replacement Credit Facility,
with a weighted average interest rate of 3.3% and available unused borrowing
capacity of approximately $359 million.

8 1/4% SENIOR SUBORDINATED NOTES DUE 2011

     On December 17, 2002, we issued $300 million in additional principal amount
of our 8 1/4% Senior Subordinated Notes Due 2011, or the old notes, pursuant to
Rule 144A under the Securities Act at a price of 103% of the principal amount,
with accrued interest from November 1, 2002. The old notes are additional debt
securities under the Indenture pursuant to which, on November 5, 2001, we issued
$275 million of our 8 1/4% Senior Subordinated Notes Due 2011. On March 14,
2002, all of the 2001 notes were exchanged in an exchange offer for an equal
principal amount of the initial exchange notes. We used the proceeds from the
sale of the old notes to finance, in part, the Acquisition. We have agreed to
file this exchange offer registration statement or, under certain circumstances,
a shelf registration statement pursuant to a registration rights agreement
relating to the old notes. In the event we fail to comply with some of our
obligations under the registration rights agreement relating to the old notes,
we will pay additional interest on the old notes. We are currently offering to
exchange up to $300 million aggregate principal amount of new 8 1/4% Senior
Subordinated Notes Due 2011, or exchange notes, that have been registered under
the Securities Act for an equal principal amount of old notes.

     The notes are senior subordinated unsecured obligations of Westport and are
fully and unconditionally guaranteed on a senior subordinated basis by some of
our existing and future restricted subsidiaries. The notes mature on November 1,
2011. We pay interest on the notes semiannually on May 1 and November 1. Our
first interest payment on the old notes will be May 1, 2003. We are entitled to
redeem the notes in whole or in part on or after November 1, 2006 for the
redemption price set forth in the notes. Prior to November 1, 2006, we are
entitled to redeem the notes, in whole but not in part, at a redemption price
equal to the principal amount of the notes plus a premium. There is no sinking
fund for the notes. If we fail to comply with some of our obligations under the
registration rights agreement relating to the old notes, we will pay additional
interest on the old notes.

                                        53


8 7/8% SENIOR SUBORDINATED NOTES DUE 2007

     In connection with our merger with and into Belco Oil & Gas Corp., or
Belco, we assumed $147 million face amount of Belco's 8 7/8% Senior Subordinated
Notes Due 2007. On November 1, 2001, approximately $24.3 million face amount of
the Belco notes was tendered to us pursuant to the change of control provisions
of the related indenture. The tender price was equal to 101% of the principal
amount of each note plus accrued and unpaid interest as of October 29, 2001.
Including the premium and accrued interest, the total amount paid was $24.8
million. We used borrowings under our previous revolving credit facility to fund
the repayment. No gain or loss was recorded in connection with the redemption as
the fair value of the 8 7/8% Senior Subordinated Notes recorded in connection
with the merger equaled the redemption cost.

                                        54


                         DESCRIPTION OF EXCHANGE NOTES

     Westport Resources Corporation will issue the exchange notes under the
Indenture dated as of November 5, 2001, as supplemented by the First
Supplemental Indenture, dated as of December 31, 2001, and the Second
Supplemental Indenture, dated as of December 17, 2002, among itself, the
subsidiary guarantors from time to time parties thereto and The Bank of New
York, as Trustee (as supplemented, the "Indenture"). The form and terms of the
exchange notes are the same as the form and terms of the old notes, except that
the exchange notes have been registered under the Securities Act, will not bear
legends restricting the transfer thereof, will not be entitled to certain
registration rights under the registration rights agreement relating to the old
notes and will have different administrative terms. The terms of the notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939.

     Certain terms used in this description are defined under the subheading
"-- Certain Definitions." In this description, the words "Company," "we," "us"
and "our" refer only to Westport Resources Corporation and not to any of its
subsidiaries.

     On November 5, 2001, we issued $275 million aggregate principal amount of
8 1/4% Senior Subordinated Notes Due 2011. On March 14, 2002, all of the 2001
notes were exchanged in an exchange offer for an equal principal amount of notes
registered under the Securities Act, or the initial exchange notes. If the
exchange offer is consummated, holders of old notes who do not exchange their
old notes for exchange notes will vote together with holders of the exchange
notes, the initial exchange notes and, if applicable, any holders of additional
notes for all relevant purposes under the Indenture. Accordingly, in determining
whether the required holders have given any notice, consent or waiver or taken
any other action permitted under the Indenture, any old notes that remain
outstanding after the exchange offer will be aggregated with the exchange notes,
the initial exchange notes and, if applicable, any additional notes, and the
holders of the old notes, the exchange notes, the initial exchange notes and the
additional notes will vote together as a single class.

     All references in this prospectus to specified percentages in aggregate
principal amount of the notes that are outstanding means, at any time after the
exchange offer is consummated, the percentage in aggregate principal amount of
the old notes, the exchange notes, the initial exchange notes and the additional
notes then outstanding, if any. The exchange notes, together with any old notes
not exchanged in the exchange offer, will represent approximately 52.2% of all
the notes issued under the Indenture as of the date of the closing of the
exchange offer.

     The following description is only a summary of the material provisions of
the Indenture. We urge you to read the Indenture because it, not this
description, define your rights as holders of the exchange notes. You may
request copies of the Indenture at our address set forth under the heading
"Where You Can Find More Information." Unless the context otherwise requires,
for all purposes of the Indenture and this "Description of Exchange Notes,"
references to the "notes" include the initial exchange notes, the old notes, the
exchange notes and any additional notes issued under the Indenture.

BRIEF DESCRIPTION OF EXCHANGE NOTES

     These exchange notes:

     - are unsecured senior subordinated obligations of the Company;

     - are subordinated in right of payment to all existing and future Senior
       Indebtedness of the Company;

     - are senior in right of payment to any future Subordinated Obligations of
       the Company;

     - are guaranteed by each Subsidiary Guarantor; and

     - have been registered under the Securities Act.

PRINCIPAL, MATURITY AND INTEREST

     We will issue up to $300.0 million principal amount of exchange notes in
this exchange offer in exchange for an equal principal amount of our old notes.
We will issue the exchange notes in denominations of $1,000
                                        55


and any integral multiple of $1,000. The notes will mature on November 1, 2011.
Subject to our compliance with the covenant described under the subheading
"-- Certain Covenants -- Limitation on Indebtedness," we are permitted to issue
more notes from time to time under the Indenture ("Additional Notes") in an
unlimited principal amount. The old notes constitute the first issuance of
Additional Notes under the Indenture. The exchange notes, any old notes not
exchanged in the exchange offer, the initial exchange notes and all subsequent
Additional Notes, if any, will be treated as a single class for all purposes of
the Indenture, including waivers, amendments, redemptions and offers to
purchase.

     Interest on the exchange notes will accrue at the rate of 8 1/4% per annum
and will be payable semiannually in arrears on May 1 and November 1, commencing
on May 1, 2003. We will make each interest payment to the holders of record of
the notes on the immediately preceding April 15 and October 15. We will pay
interest on overdue principal at 1% per annum in excess of the above rate and
will pay interest on overdue installments of interest at such higher rate to the
extent lawful.

     Interest on each exchange note will accrue from the last interest payment
date on which interest was paid on the old note surrendered in exchange thereof,
or, if the interest has not been paid on such note, from November 1, 2002.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.

     Additional interest may accrue on the notes in certain circumstances
pursuant to the applicable Registration Rights Agreement.

OPTIONAL REDEMPTION

     Except as set forth below, we will not be entitled to redeem the notes at
our option prior to November 1, 2006.

     On and after November 1, 2006, we will be entitled at our option to redeem
all or a portion of the notes upon not less than 30 nor more than 60 days'
notice, at the redemption prices (expressed in percentages of principal amount
on the redemption date), plus accrued interest to the redemption date (subject
to the right of holders of record on the relevant record date to receive
interest due on the relevant interest payment date), if redeemed during the
12-month period commencing on November 1 of the years set forth below:

</Table>

     In addition, before November 1, 2004, we may at our option on one or more
occasions redeem notes (which include subsequent Additional Notes, if any) in an
aggregate principal amount not to exceed 35% of the aggregate principal amount
of the notes (which includes subsequent Additional Notes, if any) issued prior
to the redemption date, at a redemption price (expressed as a percentage of
principal amount) of 108.25%, plus accrued and unpaid interest to the redemption
date, with the net cash proceeds from one or more Public Equity Offerings;
provided, however, that:

          (1) at least 65% of such aggregate principal amount of notes (which
     includes subsequent Additional Notes, if any) remains outstanding
     immediately after the occurrence of each such redemption (other than notes
     held, directly or indirectly, by the Company or its Affiliates); and

          (2) each such redemption occurs within 90 days after the date of the
     related Public Equity Offering.

                                        56


     We will be entitled, at our option, at any time as a whole prior to
November 1, 2006, to redeem the notes (which include subsequent Additional
Notes, if any) at a redemption price equal to the sum of:

          (1) the principal amount thereof, plus

          (2) accrued and unpaid interest, if any, to the redemption date, plus

          (3) the Applicable Premium at the redemption date.

SELECTION AND NOTICE OF REDEMPTION

     If we are redeeming less than all the notes at any time, the Trustee will
select notes on a pro rata basis, by lot or by such other method as the Trustee
in its sole discretion shall deem to be fair and appropriate.

     We will redeem notes of $1,000 or less in whole and not in part. We will
cause notices of redemption to be mailed by first-class mail at least 30 but not
more than 60 days before the redemption date to each holder of notes to be
redeemed at its registered address.

     If any note is to be redeemed in part only, the notice of redemption that
relates to that note will state the portion of the principal amount thereof to
be redeemed. We will issue a new note in a principal amount equal to the
unredeemed portion of the original note in the name of the holder upon
cancellation of the original note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to
accrue on notes or portions of them called for redemption.

MANDATORY REDEMPTION; OFFERS TO PURCHASE; OPEN MARKET PURCHASES

     We are not required to make any mandatory redemption or sinking fund
payments with respect to the notes. However, under certain circumstances, we may
be required to offer to purchase notes as described under the captions
"-- Change of Control" and "Certain Covenants -- Limitation on Sales of Assets
and Subsidiary Stock." We may at any time and from time to time purchase notes
in the open market or otherwise.

GUARANTIES

     The Subsidiary Guarantors will jointly and severally guarantee, on a senior
subordinated basis, our obligations under the notes. The Subsidiary Guarantors
include substantially all of our Subsidiaries existing on the Old Note Issue
Date and, subject to certain exceptions, will include any of our future
Restricted Subsidiaries that Incur Indebtedness. The obligations of each
Subsidiary Guarantor under its Subsidiary Guaranty will be limited as necessary
to prevent that Subsidiary Guaranty from constituting a fraudulent conveyance
under applicable law. See "Risk Factors -- Federal and state statutes allow
courts, under specific circumstances, to void guarantees and require noteholders
to return payments received from guarantors."

     Each Subsidiary Guarantor that makes a payment under its Subsidiary
Guaranty will be entitled upon payment in full of all guarantied obligations
under the Indenture to a contribution from each other Subsidiary Guarantor in an
amount equal to such other Subsidiary Guarantor's pro rata portion of such
payment based on the respective net assets of all the Subsidiary Guarantors at
the time of such payment determined in accordance with GAAP.

     If a Subsidiary Guaranty were rendered voidable, it could be subordinated
by a court to all other indebtedness (including guarantees and other contingent
liabilities) of the applicable Subsidiary Guarantor, and, depending on the
amount of such indebtedness, a Subsidiary Guarantor's liability on its
Subsidiary Guaranty could be reduced to zero. See "Risk Factors -- Federal and
state statutes allow courts, under specific circumstances, to void guarantees
and require noteholders to return payments received from guarantors."

     The Subsidiary Guaranty of a Subsidiary Guarantor will be released:

          (1) upon the sale or other disposition (including by way of
     consolidation or merger) of that Subsidiary Guarantor; or
                                        57


          (2) upon the sale or disposition of all or substantially all the
     assets of that Subsidiary Guarantor;

in each case other than to the Company or an Affiliate of the Company and as
permitted by the Indenture.

RANKING

  SENIOR INDEBTEDNESS VERSUS NOTES

     The payment of the principal of, premium, if any, and interest on the notes
and any other payment obligation of the Company in respect of the notes
(including any obligation to purchase notes) and the payment of any Subsidiary
Guaranty will be subordinate in right of payment to the prior payment in full of
all Senior Indebtedness of the Company or the relevant Subsidiary Guarantor, as
the case may be, including the obligations of the Company and such Subsidiary
Guarantor under the Replacement Credit Facility.

     As of September 30, 2002, after giving pro forma effect to the Acquisition
and the Offerings and the application of the actual and estimated net proceeds
from the Offerings and the borrowings under the Replacement Credit Facility:

          (1) the Company's Senior Indebtedness would have been approximately
     $109 million, all of which would have consisted of secured indebtedness
     under the Replacement Credit Facility; and

          (2) the Senior Indebtedness of the Subsidiary Guarantors would have
     been approximately $109 million, all of which would have consisted of their
     respective guaranties of Senior Indebtedness of the Company under the
     Replacement Credit Facility.

     Although the Indenture contains limitations on the amount of additional
Indebtedness that the Company and the Subsidiary Guarantors may incur, under
certain circumstances the amount of such Indebtedness could be substantial and,
in any case, such Indebtedness may be Senior Indebtedness. See "-- Certain
Covenants -- Limitation on Indebtedness."

  LIABILITIES OF SUBSIDIARIES VERSUS NOTES

     A substantial portion of our operations are conducted through our
subsidiaries. Some of our subsidiaries are not guaranteeing the notes. Claims of
creditors of such non-guarantor subsidiaries, including trade creditors and
creditors holding indebtedness or guarantees issued by such non-guarantor
subsidiaries, and claims of preferred stockholders of such non-guarantor
subsidiaries generally will have priority with respect to the assets and
earnings of such non-guarantor subsidiaries over the claims of our creditors,
including holders of the notes, even if such claims do not constitute Senior
Indebtedness. Accordingly, the notes will be effectively subordinated to
creditors (including trade creditors) and preferred stockholders, if any, of
such non-guarantor subsidiaries.

     At September 30, 2002, our subsidiaries (other than the Subsidiary
Guarantors existing as of the Old Note Issue Date) had no significant
liabilities. Although the Indenture limits the incurrence of Indebtedness and
preferred stock of certain of our subsidiaries, such limitation is subject to a
number of significant qualifications. Moreover, the Indenture does not impose
any limitation on the incurrence by such subsidiaries of liabilities that are
not considered Indebtedness under the Indenture. See "-- Certain Covenants --
Limitation on Indebtedness."

  OTHER SENIOR SUBORDINATED INDEBTEDNESS VERSUS NOTES

     Only Indebtedness of the Company or a Subsidiary Guarantor that is Senior
Indebtedness will rank senior to the notes and the relevant Subsidiary Guaranty
in accordance with the provisions of the Indenture. The notes and each
Subsidiary Guaranty will in all respects rank pari passu with all other Senior
Subordinated Indebtedness of the Company and the relevant Subsidiary Guarantor,
respectively (including the obligations of the Company and such Subsidiary
Guarantor with respect to the Existing Notes).

                                        58


     As of September 30, 2002, after giving pro forma effect to the Acquisition,
the Offerings and the application of the actual and estimated net proceeds from
the Offerings:

          (1) the Company's Senior Subordinated Indebtedness would have been
     approximately $698 million, consisting of $300 million of the old notes,
     $275 million of Senior Subordinated Indebtedness evidenced by the initial
     exchange notes and $123 million of Senior Subordinated Indebtedness
     represented by the Existing Notes; and

          (2) the Senior Subordinated Indebtedness of the Subsidiary Guarantors
     would have been approximately $698 million, consisting of their respective
     Guarantees of Senior Subordinated Indebtedness of the Company represented
     by the old notes, the initial exchange notes and the Existing Notes.

     We and the Subsidiary Guarantors have agreed in the Indenture that we and
they will not Incur, directly or indirectly, any Indebtedness that is
contractually subordinate or junior in right of payment to our Senior
Indebtedness or the Senior Indebtedness of such Subsidiary Guarantors, unless
such Indebtedness is Senior Subordinated Indebtedness of the applicable Person
or is expressly subordinated in right of payment to Senior Subordinated
Indebtedness of such Person. The Indenture does not treat unsecured Indebtedness
as subordinated or junior to Secured Indebtedness merely because it is
unsecured.

  PAYMENT OF NOTES

     We are not permitted to pay principal of, premium, if any, or interest on
the notes or any other payment obligation of the Company in respect of the notes
(including any obligation to purchase the notes) or make any deposit pursuant to
the provisions described under "-- Defeasance" below and may not purchase,
redeem or otherwise retire any notes (collectively, "pay the notes") if either
of the following occurs (a "Payment Default"):

          (1) a default in the payment of any principal of, premium, if any, or
     interest on Designated Senior Indebtedness of the Company occurs; or

          (2) any other default on Designated Senior Indebtedness of the Company
     occurs and the maturity of such Designated Senior Indebtedness is
     accelerated in accordance with its terms;

unless, in either case, the Payment Default has been cured or waived and any
such acceleration has been rescinded or such Designated Senior Indebtedness has
been paid in full in cash. If a distribution is made to holders of the notes
that, due to the foregoing provisions limiting payments on the notes, should not
have been made to them, such holders of the notes are required to hold it in
trust for the holders of Senior Indebtedness of the Company and pay it over to
them as their interests may appear. Regardless of the foregoing, we are
permitted to pay the notes if we and the Trustee receive written notice
approving such payment from the Representatives of all Designated Senior
Indebtedness with respect to which the Payment Default has occurred and is
continuing.

     During the continuance of any default (other than a Payment Default) with
respect to any Designated Senior Indebtedness pursuant to which the maturity
thereof may be accelerated without further notice (except such notice as may be
required to effect such acceleration) or the expiration of any applicable grace
periods, we are not permitted to pay the notes for a period (a "Payment Blockage
Period") commencing upon the receipt by the Trustee (with a copy to us) of
written notice (a "Blockage Notice") of such default from the Representative of
such Designated Senior Indebtedness specifying an election to effect a Payment
Blockage Period and ending 179 days thereafter. The Payment Blockage Period will
end earlier if such Payment Blockage Period is terminated:

          (1) by written notice to the Trustee and us from the Person or Persons
     who gave such Blockage Notice;

          (2) because the default giving rise to such Blockage Notice is cured,
     waived or otherwise no longer continuing; or

          (3) because such Designated Senior Indebtedness has been discharged or
     repaid in full in cash.

                                        59


     Notwithstanding the provisions described above, unless the holders of such
Designated Senior Indebtedness or the Representative of such Designated Senior
Indebtedness have accelerated the maturity of such Designated Senior
Indebtedness, we are permitted to resume paying the notes after the end of such
Payment Blockage Period. The notes shall not be subject to more than one Payment
Blockage Period in any consecutive 360-day period irrespective of the number of
defaults with respect to Designated Senior Indebtedness during such period,
except that if any Blockage Notice is delivered to the Trustee by or on behalf
of holders of Designated Senior Indebtedness (other than holders of the Bank
Indebtedness), a Representative of holders of Bank Indebtedness may give another
Blockage Notice within such period. However, in no event may the total number of
days during which any Payment Blockage Period or Periods is in effect exceed 179
days in the aggregate during any consecutive 360-day period, and there must be
181 days during any consecutive 360-day period during which no Payment Blockage
Period is in effect.

     Upon any payment or distribution of the assets of the Company upon a total
or partial liquidation or dissolution or reorganization of or similar proceeding
relating to the Company or its property:

          (1) the holders of Senior Indebtedness of the Company will be entitled
     to receive payment in full in cash of such Senior Indebtedness before the
     holders of the notes are entitled to receive any payment;

          (2) until the Senior Indebtedness of the Company is paid in full in
     cash, any payment or distribution to which holders of the notes would be
     entitled but for the subordination provisions of the Indenture will be made
     to holders of such Senior Indebtedness as their interests may appear,
     except that holders of notes may receive certain Capital Stock and
     subordinated debt obligations; and

          (3) if a distribution is made to holders of the notes that, due to the
     subordination provisions, should not have been made to them, such holders
     of the notes are required to hold it in trust for the holders of Senior
     Indebtedness of the Company and pay it over to them as their interests may
     appear.

     To the extent any payment of or distribution in respect of Senior
Indebtedness (whether by or on behalf of the Company or any Subsidiary
Guarantor, if any, as proceeds of security or enforcement of any right of setoff
or otherwise) is declared to be fraudulent or preferential, set aside or
required to be paid to any receiver, trustee in bankruptcy, liquidating trustee,
agent or other similar Person under any bankruptcy, insolvency, receivership,
fraudulent conveyance or similar law, then if such payment or distribution is
recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating
trustee, agent or other similar Person, the Senior Indebtedness or part thereof
originally intended to be satisfied shall be deemed to be reinstated and
outstanding as if such payment had not occurred.

     If payment of the notes is accelerated because of an Event of Default, the
Company or the Trustee must promptly notify the holders of Designated Senior
Indebtedness or the Representative of such Designated Senior Indebtedness of the
acceleration.

     A Subsidiary Guarantor's obligations under its Subsidiary Guaranty are
senior subordinated obligations. As such, the rights of noteholders to receive
payment by a Subsidiary Guarantor pursuant to its Subsidiary Guaranty will be
subordinated in right of payment to the rights of holders of Senior Indebtedness
of such Subsidiary Guarantor. The terms of the subordination provisions
described above with respect to the Company's obligations under the notes apply
equally to a Subsidiary Guarantor and the obligations of such Subsidiary
Guarantor under its Subsidiary Guaranty.

     By reason of the subordination provisions contained in the Indenture, in
the event of a liquidation or insolvency proceeding, creditors of the Company or
a Subsidiary Guarantor who are holders of Senior Indebtedness of the Company or
a Subsidiary Guarantor, as the case may be, may recover more, ratably, than the
holders of the notes, and creditors of ours who are not holders of Senior
Indebtedness may recover less, ratably, than holders of Senior Indebtedness and
may recover more, ratably, than the holders of the notes.

     No right of any present or future holders of any Senior Indebtedness to
enforce subordination as provided in the Indenture will at any time in any way
be prejudiced or impaired by noncompliance by the Company or any Subsidiary
Guarantor (if any) with the terms of the Indenture, regardless of any knowledge
thereof that any such holder of Senior Indebtedness may have or otherwise be
charged with. The subordination provisions

                                        60


of the Indenture are intended to be for the benefit of, and shall be enforceable
directly by, the holders of Senior Indebtedness.

     Each holder of notes by the holder's acceptance thereof authorizes and
directs the Trustee on the holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in the
Indenture, and appoints the Trustee to act as the holder's attorney-in-fact for
any and all such purposes.

     The holders of Senior Indebtedness may, at any time and from time to time
subject to the terms of such Senior Indebtedness, without the consent of or
notice to the Trustee or the holders of the notes, without incurring
responsibility to the holders of the notes and without impairing or releasing
the subordination provided in the Indenture or the obligations hereunder of the
holders of the notes to the holders of Senior Indebtedness, do any one or more
of the following: (a) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, Senior Indebtedness or any instrument
evidencing the same or any agreement under which Senior Indebtedness is
outstanding or secured; (b) sell, exchange, release or otherwise deal with any
property pledged, mortgaged or otherwise securing Senior Indebtedness; (c)
release any Person liable in any manner for the collection of Senior
Indebtedness; and (d) exercise or refrain from exercising any rights against the
Company and each Subsidiary Guarantor (if any) and any other Person.

     The terms of the subordination provisions described above will not apply to
payments from money or the proceeds of U.S. Government Obligations held in trust
by the Trustee for the payment of principal of and interest on the notes
pursuant to the provisions described under "-- Defeasance."

BOOK-ENTRY, DELIVERY AND FORM

     We will issue the exchange notes in the form of one or more global notes
(the "Global Exchange Note"). The Global Exchange Note will be deposited with,
or on behalf of, The Depository Trust Company (the "Depository") and registered
in the name of the Depository or its nominee. Except as set forth below, the
Global Exchange Note may be transferred, in whole and not in part, and only to
the Depository or another nominee of the Depository. You may hold your
beneficial interests in the Global Exchange Note directly through the Depository
if you have an account with the Depository or indirectly through organizations
that have accounts with the Depository.

     The Depository has advised the Company as follows: the Depository is a
limited-purpose trust company organized under the laws of the State of New York,
a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and "a clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. The
Depository was created to hold securities of institutions that have accounts
with the Depository ("participants") and to facilitate the clearance and
settlement of securities transactions among its participants in such securities
through electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. The
Depository's participants include securities brokers and dealers (which may
include the initial purchasers), banks, trust companies, clearing corporations
and certain other organizations. Access to the Depository's book-entry system is
also available to others such as banks, brokers, dealers and trust companies
(collectively, the "indirect participants") that clear through or maintain a
custodial relationship with a participant, whether directly or indirectly.

     The Company expects that pursuant to procedures established by the
Depository, upon the deposit of the Global Exchange Note with the Depository,
the Depository will credit, on its book-entry registration and transfer system,
the principal amount of notes represented by such Global Exchange Note to the
accounts of participants. The accounts to be credited shall be designated by the
initial purchasers. Ownership of beneficial interests in the Global Exchange
Note will be limited to participants or persons that may hold interests through
participants. Ownership of beneficial interests in the Global Exchange Note will
be shown on, and the transfer of those ownership interests will be effected only
through, records maintained by the Depository (with respect to participants'
interests), the participants and the indirect participants (with respect to the
owners of beneficial interests in the Global Exchange Note other than
participants). The laws of some jurisdictions may require that certain
purchasers of securities take physical delivery of such securities in definitive
form. Such limits and laws may impair the ability to transfer or pledge
beneficial interests in the Global Exchange Note.
                                        61


     So long as the Depository, or its nominee, is the registered holder and
owner of the Global Exchange Note, the Depository or such nominee, as the case
may be, will be considered the sole legal owner and holder of any related notes
evidenced by the Global Exchange Note for all purposes of such notes and the
Indenture. Except as set forth below, as an owner of a beneficial interest in
the Global Exchange Note, you will not be entitled to have the notes represented
by the Global Exchange Note registered in your name, will not receive or be
entitled to receive physical delivery of certificated notes and will not be
considered to be the owner or holder of any notes under the Global Exchange
Note. We understand that under existing industry practice, in the event an owner
of a beneficial interest in the Global Exchange Note desires to take any action
that the Depository, as the holder of the Global Exchange Note, is entitled to
take, the Depository would authorize the participants to take such action, and
the participants would authorize beneficial owners owning through such
participants to take such action or would otherwise act upon the instructions of
beneficial owners owning through them.

     We will make payments of principal of, premium, if any, and interest on
notes represented by the Global Exchange Note registered in the name of and held
by the Depository or its nominee to the Depository or its nominee, as the case
may be, as the registered owner and holder of the Global Exchange Note.

     We expect that the Depository or its nominee, upon receipt of any payment
of principal of, premium, if any, or interest on the Global Exchange Note will
credit participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the Global Exchange
Note as shown on the records of the Depository or its nominee. We also expect
that payments by participants or indirect participants to owners of beneficial
interests in the Global Exchange Note held through such participants or indirect
participants will be governed by standing instructions and customary practices
and will be the responsibility of such participants or indirect participants. We
will not have any responsibility or liability for any aspect of the records
relating to, or payments made on account of, beneficial ownership interests in
the Global Exchange Note for any exchange note or for maintaining, supervising
or reviewing any records relating to such beneficial ownership interests or for
any other aspect of the relationship between the Depository and its participants
or indirect participants or the relationship between such participants or
indirect participants and the owners of beneficial interests in the Global
Exchange Note owning through such participants.

     Although the Depository has agreed to the foregoing procedures in order to
facilitate transfers of interests in the Global Exchange Note among participants
of the Depository, it is under no obligation to perform or continue to perform
such procedures, and such procedures may be discontinued at any time. Neither
the Trustee nor the Company will have any responsibility or liability for the
performance by the Depository or its participants or indirect participants of
their respective obligations under the rules and procedures governing their
operations.

CERTIFICATED NOTES

     Subject to certain conditions, the exchange notes represented by the Global
Exchange Note are exchangeable for certificated notes in definitive form of like
tenor in denominations of $1,000 and integral multiples thereof if:

          (1) the Depository notifies us that it is unwilling or unable to
     continue as Depository for the Global Exchange Note or the Depository
     ceases to be a clearing agency registered under the Exchange Act and, in
     either case, we are unable to locate a qualified successor within 90 days;

          (2) we in our discretion at any time determine not to have all the
     exchange notes represented by the Global Exchange Note; or

          (3) a default entitling the holders of the notes to accelerate the
     maturity thereof has occurred and is continuing.

     Any exchange notes that are exchangeable as described above are
exchangeable for certificated notes issuable in authorized denominations and
registered in such names as the Depository shall direct. Subject to the
foregoing, the Global Exchange Note is not exchangeable, except for a Global
Exchange Note of the same aggregate denomination to be registered in the name of
the Depository or its nominee. In addition, such
                                        62


certificates will bear a restrictive legend (unless we determine that a
restrictive legend is not required in accordance with applicable law), subject,
with respect to such certificated notes, to the provisions of such legend.

SAME-DAY PAYMENT

     The Indenture requires us to make payments in respect of notes (including
principal, premium and interest) by wire transfer of immediately available funds
to the U.S. dollar accounts with banks in the U.S. specified by the holders
thereof or, if no such account is specified, by mailing a check to each such
holder's registered address.

REGISTERED EXCHANGE OFFER; REGISTRATION RIGHTS

     Upon the closing of the offering of the old notes, we, the Subsidiary
Guarantors and the Initial Purchasers entered into the Registration Rights
Agreement relating to the old notes, which provides for this exchange offer. A
copy of the Registration Rights Agreement relating to the old notes is filed as
an exhibit to the registration statement of which this prospectus is a part.
Please read the section captioned "The Exchange Offer" for more details
regarding the terms of the Registration Rights Agreement relating to the old
notes and the exchange offer.

CHANGE OF CONTROL

     Upon the occurrence of any of the following events (each a "Change of
Control"), then unless the Company shall have exercised its right to redeem all
the notes, each noteholder shall have the right to require that the Company
repurchase such holder's notes at a purchase price in cash equal to 101% of the
principal amount thereof on the date of purchase plus accrued and unpaid
interest, if any, to the date of purchase (subject to the right of holders of
record on the relevant record date to receive interest due on the relevant
interest payment date):

          (1) any "person" (as such term is used in Sections 13(d) and 14(d) of
     the Exchange Act), other than any one or more of the Permitted Holders, is
     or becomes the "beneficial owner" (as defined in Rules 13d-3 and 13d-5
     under the Exchange Act, except that for purposes of this clause (1) such
     person shall be deemed to have "beneficial ownership" of all shares that
     any such person has the right to acquire, whether such right is exercisable
     immediately or only after the passage of time), directly or indirectly, of
     more than 40% of the total voting power of the Voting Stock of the Company;
     provided, however, that the Permitted Holders beneficially own (as defined
     in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly,
     in the aggregate a lesser percentage of the total voting power of the
     Voting Stock of the Company than such other person and do not have the
     right or ability by voting power, contract or otherwise to elect or
     designate for election a majority of the Board of Directors (for the
     purposes of this clause (1), such other person shall be deemed to
     beneficially own any Voting Stock of the Company held by a parent entity,
     if such other person is the beneficial owner (as defined in this clause
     (1)), directly or indirectly, of more than 40% of the voting power of the
     Voting Stock of such parent entity and the Permitted Holders beneficially
     own (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly
     or indirectly, in the aggregate a lesser percentage of the voting power of
     the Voting Stock of such parent entity and do not have the right or ability
     by voting power, contract or otherwise to elect or designate for election a
     majority of the board of directors of such parent entity);

          (2) during any period of two consecutive years, individuals who at the
     beginning of such period constituted the Board of Directors (together with
     (A) any new directors whose election by such Board of Directors or whose
     nomination for election by the shareholders of the Company was approved by
     a vote of the majority of the directors of the Company then still in office
     who were either directors at the beginning of such period or whose election
     or nomination for election was previously so approved and (B) any
     representative of a Permitted Holder) cease for any reason to constitute a
     majority of the Board of Directors then in office;

          (3) the adoption of a plan relating to the liquidation or dissolution
     of the Company; or
                                        63


          (4) the merger or consolidation of the Company with or into another
     Person or the merger of another Person with or into the Company, or the
     sale of all or substantially all the assets of the Company (determined on a
     consolidated basis) to another Person (other than a Permitted Holder),
     other than a transaction following which (A) in the case of a merger or
     consolidation transaction, holders of securities that represented 100% of
     the Voting Stock of the Company immediately prior to such transaction (or
     other securities into which such securities are converted as part of such
     merger or consolidation transaction) own directly or indirectly at least a
     majority of the voting power of the Voting Stock of the surviving Person in
     such merger or consolidation transaction immediately after such transaction
     and (B) in the case of a sale of assets transaction, the transferee Person
     becomes the obligor in respect of the notes and a Subsidiary of the
     transferor of such assets.

     Unless the Company has exercised its right to redeem all the notes and
shall have delivered an irrevocable notice of redemption to the Trustee, then
within 30 days following any Change of Control, we will mail a notice to each
noteholder with a copy to the Trustee (the "Change of Control Offer") stating:

          (1) that a Change of Control has occurred and that such holder has the
     right to require us to purchase such holder's notes at a purchase price in
     cash equal to 101% of the principal amount thereof on the date of purchase,
     plus accrued and unpaid interest, if any, to the date of purchase (subject
     to the right of holders of record on the relevant record date to receive
     interest on the relevant interest payment date);

          (2) the circumstances and relevant facts regarding such Change of
     Control (including information with respect to pro forma historical income,
     cash flow and capitalization, in each case after giving effect to such
     Change of Control);

          (3) the purchase date (which shall be no earlier than 30 days nor
     later than 60 days from the date such notice is mailed); and

          (4) the instructions, as determined by us, consistent with the
     covenant described hereunder, that a holder must follow in order to have
     its notes purchased.

     The Replacement Credit Facility prohibits us from purchasing any notes
except in certain specified circumstances if our senior unsecured debt rating is
BB or less by S&P or Ba2 or less by Moody's, and also provides that the
occurrence of certain change of control events with respect to the Company would
constitute a default thereunder. In the event that at the time of a Change of
Control, the terms of the Replacement Credit Facility prohibit the Company from
making a Change of Control Offer or from purchasing the notes pursuant thereto,
the Company shall, prior to the mailing of the notice to noteholders described
in the preceding paragraph, but in any event within 30 days following any Change
of Control:

          (1) repay in full all Indebtedness outstanding under the Replacement
     Credit Facility or offer to repay in full all such Indebtedness and repay
     the Indebtedness of each lender who has accepted such offer; or

          (2) obtain the requisite consent under the Replacement Credit Facility
     to permit the purchase of the notes as described above.

     The Company must first comply with the covenant described above before it
will be required to purchase notes in the event of a Change of Control,
provided, however, that the Company's failure to comply with the covenant
described in the preceding sentence or to make a Change of Control Offer because
of any such failure shall constitute a default described in clause (4) under
"-- Defaults" below (and not under clause (2) thereof). As a result of the
foregoing, a holder of the notes may not be able to compel the Company to
purchase the notes unless the Company is able at the time to refinance all
Indebtedness outstanding under the Replacement Credit Facility or obtain
requisite consents under the Replacement Credit Facility.

     We will not be required to make a Change of Control Offer following a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by us and
purchases all notes validly tendered and not withdrawn under such Change of
Control Offer.

                                        64


     We will comply, to the extent applicable, with the requirements of Section
14(e) of the Exchange Act and any other securities laws or regulations in
connection with the repurchase of notes as a result of a Change of Control. To
the extent that the provisions of any securities laws or regulations conflict
with the provisions of the covenant described hereunder, we will comply with the
applicable securities laws and regulations and shall not be deemed to have
breached our obligations under the covenant described hereunder by virtue of our
compliance with such securities laws or regulations.

     The Change of Control purchase feature of the notes may in certain
circumstances make more difficult or discourage a sale or takeover of the
Company and, thus, the removal of incumbent management. The Change of Control
purchase feature is a result of negotiations between the Company and the initial
purchasers. We have no present intention to engage in a transaction involving a
Change of Control, although it is possible that we could decide to do so in the
future. Subject to the limitations discussed below, we could, in the future,
enter into certain transactions, including acquisitions, refinancings or other
recapitalizations, that would not constitute a Change of Control under the
Indenture, but that could increase the amount of indebtedness outstanding at
such time or otherwise affect our capital structure or credit ratings.
Restrictions on our ability to Incur additional Indebtedness are contained in
the covenants described under "-- Certain Covenants -- Limitation on
Indebtedness." Such restrictions can be waived with the consent of the holders
of a majority in principal amount of the notes then outstanding. The covenants
set forth in the Indenture may not afford noteholders protection in the event of
a highly leveraged transaction.

     Future indebtedness that we may incur may contain prohibitions on the
occurrence of certain events that would constitute a Change of Control or
require the repurchase of such indebtedness upon a Change of Control. Moreover,
the exercise by the holders of their right to require us to repurchase the notes
could cause a default under such indebtedness, even if the Change of Control
itself does not, due to the financial effect of such repurchase on us. Finally,
our ability to pay cash to the holders of notes following the occurrence of a
Change of Control may be limited by our then existing financial resources. There
can be no assurance that sufficient funds will be available when necessary to
make any required repurchases.

     The definition of "Change of Control" includes the sale of all or
substantially all of the assets of the Company (determined on a consolidated
basis) to another Person. Although there is a limited body of case law
interpreting the phrase "substantially all," there is no precise established
definition of the phrase under applicable law. Accordingly, in certain
circumstances there may be a degree of uncertainty as to whether a particular
transaction would involve a disposition of "all or substantially all" of the
assets of the Company. As a result, it may be unclear as to whether a Change of
Control has occurred and whether a holder of notes may require the Company to
make an offer to repurchase the notes as described above.

     The provisions under the Indenture relative to our obligation to make an
offer to repurchase the notes as a result of a Change of Control may be waived
or modified with the written consent of the holders of a majority in principal
amount of the notes.

CERTAIN COVENANTS

     The Indenture contains covenants including, among others, the following:

  COVENANT SUSPENSION

     During any period that the notes have a rating equal to or higher than BBB-
by S&P and Baa3 by Moody's ("Investment Grade Ratings") and no Default has
occurred and is continuing, the Company and the Restricted Subsidiaries will not
be subject to the following covenants:

          (a) paragraphs (a) through (d) of the covenant described under
     "-- Limitation on Indebtedness;"

          (b) "-- Limitation on Restricted Payments;"

          (c) "-- Limitation on Restrictions on Distributions from Restricted
     Subsidiaries;"

          (d) "-- Limitation on Sales of Assets and Subsidiary Stock;"

                                        65


          (e) "-- Limitation on Affiliate Transactions;"

          (f) clause (3) of the covenant described under "-- Merger and
     Consolidation;" and

          (g) "-- Future Guarantors,"

(collectively, the "Suspended Covenants"). In the event that the Company and the
Restricted Subsidiaries are not subject to the Suspended Covenants for any
period of time as a result of the preceding sentence, and subsequently one or
both of S&P and Moody's downgrades the rating assigned to the notes below BBB-,
in the case of S&P, and below Baa3, in the case of Moody's, then the Company and
the Restricted Subsidiaries will thereafter again be subject to the Suspended
Covenants, and, with respect to Restricted Payments proposed to be made after
the time of such downgrade, the permissibility of such proposed Restricted
Payments will be calculated in accordance with the terms of the covenant
described below under "-- Limitation on Restricted Payments" as though such
covenant had been in effect since the Issue Date.

     Subject to the provisions described under "Amendments and Waivers," if the
Indenture is amended by eliminating the subordination provisions contained
therein, including those set out in paragraph (e) of the covenant described
under "-- Limitation on Indebtedness," in connection with achieving Investment
Grade Ratings for the notes or otherwise, then, in addition to the suspension of
the Suspended Covenants described above and the suspension of the covenant
described under "-- Limitation on Liens," the Indenture will also be amended by
adding covenants, in the form attached as an annex to the Indenture, limiting
the Company and the Restricted Subsidiaries' ability to Incur or permit to exist
Liens on their properties or enter into any Sale/ Leaseback Transactions.

  LIMITATION ON INDEBTEDNESS

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
Incur, directly or indirectly, any Indebtedness; provided, however, that the
Company and the Subsidiary Guarantors will be entitled to Incur Indebtedness if,
on the date of such Incurrence and after giving effect thereto on a pro forma
basis, no Default has occurred and is continuing and the Consolidated Coverage
Ratio exceeds 2.5 to 1.

     (b) Notwithstanding the foregoing paragraph (a), the Company and the
Restricted Subsidiaries will be entitled to Incur any or all of the following
Indebtedness:

          (1) Indebtedness Incurred pursuant to Credit Facilities; provided,
     however, that, after giving effect to any such Incurrence, the aggregate
     principal amount of all Indebtedness Incurred under this clause (1) and
     then outstanding does not exceed the greater of (A) $500 million less the
     sum of all principal payments with respect to such Indebtedness pursuant to
     paragraph (a)(3)(A) of the covenant described under "-- Limitation on Sales
     of Assets and Subsidiary Stock" and (B) $250 million plus 20% of ACNTA as
     of the date of such Incurrence;

          (2) Indebtedness owed to and held by the Company or a Wholly Owned
     Subsidiary; provided, however, that (A) any subsequent issuance or transfer
     of any Capital Stock which results in any such Wholly Owned Subsidiary
     ceasing to be a Wholly Owned Subsidiary or any subsequent transfer of such
     Indebtedness (other than to the Company or a Wholly Owned Subsidiary) shall
     be deemed, in each case, to constitute the Incurrence of such Indebtedness
     by the obligor thereon and (B) if the Company is the obligor on such
     Indebtedness, unless such Indebtedness is owing to a Subsidiary Guarantor,
     such Indebtedness is expressly subordinated to the prior payment in full in
     cash of all obligations with respect to the notes;

          (3) the notes (excluding the old notes, the exchange notes and any
     other Additional Notes) and all Subsidiary Guaranties;

          (4) Indebtedness outstanding on the Issue Date (other than
     Indebtedness described in clause (1), (2) or (3) of this covenant)
     including the Existing Notes;

          (5) Indebtedness of a Restricted Subsidiary Incurred and outstanding
     on or prior to the date on which such Subsidiary became a Restricted
     Subsidiary or was acquired by the Company (other than

                                        66


     Indebtedness Incurred in connection with, or to provide all or any portion
     of the funds or credit support utilized to consummate, the transaction or
     series of related transactions pursuant to which such Subsidiary became a
     Restricted Subsidiary or was acquired by the Company); provided, however,
     that on the date such Subsidiary became a Restricted Subsidiary or was
     acquired by the Company and after giving pro forma effect thereto, the
     Company would have been able to Incur at least $1.00 of additional
     Indebtedness pursuant to paragraph (a) of this covenant;

          (6) Refinancing Indebtedness in respect of Indebtedness Incurred
     pursuant to paragraph (a) or pursuant to clause (3), (4) or (5) or this
     clause (6); provided, however, that to the extent such Refinancing
     Indebtedness directly or indirectly Refinances Indebtedness of a Restricted
     Subsidiary Incurred pursuant to clause (5), such Refinancing Indebtedness
     shall be Incurred only by such Restricted Subsidiary or, so long as such
     Restricted Subsidiary has no liability with respect to such Refinancing
     Indebtedness, by the Company or a Subsidiary Guarantor;

          (7) Indebtedness consisting of Guarantees of production or payment
     with respect to Production Payments; provided, however, that the Net
     Present Value of the reserves related to such Production Payments shall not
     exceed 2.5% of ACNTA at the time of Incurrence;

          (8) Hedging Obligations consisting of Interest Rate Agreements related
     to Indebtedness outstanding on the Issue Date or permitted to be Incurred
     by the Company and the Restricted Subsidiaries pursuant to the Indenture;

          (9) Hedging Obligations consisting of Oil and Natural Gas Hedging
     Contracts and Currency Agreements entered into in the ordinary course of
     business for the purpose of limiting risks that arise in the ordinary
     course of business of the Company and its Subsidiaries;

          (10) obligations in respect of performance, bid and surety bonds,
     including Guarantees and letters of credit functioning as or supporting
     such performance, bid and surety bonds, completion guarantees and other
     reimbursement obligations provided by the Company or any Restricted
     Subsidiary in the ordinary course of business (in each case other than for
     an obligation for money borrowed);

          (11) Indebtedness arising from the honoring by a bank or other
     financial institution of a check, draft or similar instrument drawn against
     insufficient funds in the ordinary course of business; provided, however,
     that such Indebtedness is extinguished within two Business Days of its
     Incurrence;

          (12) Indebtedness consisting of any Guarantee by the Company or a
     Subsidiary Guarantor of Indebtedness of the Company or a Subsidiary
     Guarantor outstanding on the Issue Date or permitted by the Indenture to be
     Incurred by the Company or a Subsidiary Guarantor;

          (13) Indebtedness represented by Capital Lease Obligations, mortgage
     financings or purchase money obligations, in each case, Incurred for the
     purpose of financing all or any part of the purchase price, cost of
     construction or improvement or carrying cost of assets used in the business
     of the Company and its Restricted Subsidiaries and related financing costs,
     and Refinancing Indebtedness Incurred to Refinance any Indebtedness
     Incurred pursuant to this clause, in an aggregate principal amount at any
     one time outstanding not to exceed $20 million;

          (14) Indebtedness arising from any agreement providing for
     indemnities, Guarantees, purchase price adjustments, holdbacks, contingency
     payment obligations based on the performance of the acquired or disposed
     assets or similar obligations (other than Guarantees of Indebtedness)
     Incurred by any Person in connection with the acquisition or disposition of
     assets;

          (15) in-kind obligations relating to net oil or natural gas balancing
     positions arising in the ordinary course of business; and

          (16) Indebtedness of the Company or its Restricted Subsidiaries in an
     aggregate principal amount which, when taken together with all other
     Indebtedness of the Company and its Restricted Subsidiaries outstanding on
     the date of such Incurrence (other than Indebtedness permitted by clauses
     (1) through

                                        67


     (15) above or paragraph (a)) does not exceed $25 million, of which not more
     than $10 million may be Indebtedness of Restricted Subsidiaries that are
     not Subsidiary Guarantors.

     (c) Notwithstanding the foregoing, the Company will not, and will not
permit any Subsidiary Guarantor to, Incur any Indebtedness pursuant to the
foregoing paragraph (b) if the proceeds thereof are used, directly or
indirectly, to Refinance any Subordinated Obligations of the Company or any
Subsidiary Guarantor unless such Indebtedness shall be subordinated to the notes
or the applicable Subsidiary Guaranty to at least the same extent as such
Subordinated Obligations.

     (d) For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Indebtedness described above (including paragraph (a) above), (1)
the Company, in its sole discretion may classify such item of Indebtedness at
the time of Incurrence, in any manner in compliance with this covenant, (2) the
Company will only be required to include the amount and type of such
Indebtedness in one of the above categories and (3) the Company will be entitled
to divide and classify such item of Indebtedness in more than one of the
categories of Indebtedness described above.

     (e) Notwithstanding paragraphs (a) and (b) above, the Company will not, and
will not permit any Subsidiary Guarantor to, Incur any Indebtedness if such
Indebtedness is subordinate or junior in ranking in right of payment to any
Senior Indebtedness of such Person, unless such Indebtedness is Senior
Subordinated Indebtedness of such Person or is expressly subordinated in right
of payment to Senior Subordinated Indebtedness of such Person.

  LIMITATION ON RESTRICTED PAYMENTS

     (a) The Company will not, and will not permit any Restricted Subsidiary,
directly or indirectly, to make a Restricted Payment if at the time the Company
or such Restricted Subsidiary makes such Restricted Payment:

          (1) a Default shall have occurred and be continuing (or would result
     therefrom);

          (2) the Company is not entitled to Incur an additional $1.00 of
     Indebtedness pursuant to paragraph (a) of the covenant described under
     "-- Limitation on Indebtedness;" or

          (3) the aggregate amount of such Restricted Payment and all other
     Restricted Payments since the Issue Date would exceed the sum of (without
     duplication):

             (A) 50% of the Consolidated Net Income accrued during the period
        (treated as one accounting period) from the beginning of the fiscal
        quarter immediately following the fiscal quarter during which the Issue
        Date occurs to the end of the most recent fiscal quarter ending at least
        45 days prior to the date of such Restricted Payment (or, in case such
        Consolidated Net Income shall be a deficit, minus 100% of such deficit);
        plus

             (B) 100% of the aggregate Net Cash Proceeds or the fair market
        value of property other than cash (including Capital Stock of Persons
        engaged in the Oil and Gas Business or assets used in the Oil and Gas
        Business) received by the Company from the issuance or sale of its
        Capital Stock (other than Disqualified Stock) subsequent to the Issue
        Date (other than an issuance or sale to a Subsidiary of the Company and
        other than an issuance or sale to an employee stock ownership plan or to
        a trust established by the Company or any of its Subsidiaries for the
        benefit of their employees) and 100% of any capital contribution
        received by the Company from its shareholders subsequent to the Issue
        Date; plus

             (C) the aggregate Net Cash Proceeds received by the Company
        subsequent to the Issue Date from the issuance or sale of its Capital
        Stock (other than Disqualified Stock) to an employee stock ownership
        plan or to a trust established by the Company or any of its Subsidiaries
        for the benefit of their employees; provided, however, that if such
        employee stock ownership plan or trust Incurs any Indebtedness to
        finance the purchase of such Capital Stock, such aggregate amount shall
        be limited to the excess of such Net Cash Proceeds over the amount of
        such Indebtedness plus an amount
                                        68


        equal to any increase in the Consolidated Net Worth of the Company
        resulting from principal repayments made from time to time by such
        employee stock ownership plan or trust with respect to such
        Indebtedness; plus

             (D) the amount by which Indebtedness of the Company is reduced on
        the Company's balance sheet upon the conversion or exchange (other than
        by a Subsidiary of the Company) subsequent to the Issue Date of any
        Indebtedness of the Company convertible or exchangeable for Capital
        Stock (other than Disqualified Stock) of the Company (less the amount of
        any cash, or the fair value of any other property, distributed by the
        Company upon such conversion or exchange); plus

             (E) an amount equal to the sum of (x) the net reduction in the
        Investments (other than Permitted Investments) made by the Company or
        any Restricted Subsidiary in any Person resulting from repurchases,
        repayments or redemptions of such Investments by such Person, proceeds
        realized on the sale of such Investment and proceeds representing the
        return of capital (excluding dividends and distributions), in each case
        received by the Company or any Restricted Subsidiary and (y) to the
        extent such Person is an Unrestricted Subsidiary, the portion
        (proportionate to the Company's equity interest in such Subsidiary) of
        the fair market value of the net assets of such Unrestricted Subsidiary
        at the time such Unrestricted Subsidiary is designated a Restricted
        Subsidiary; provided, however, that to the extent the foregoing sum
        exceeds, in the case of any such Person or Unrestricted Subsidiary, the
        amount of Investments (excluding Permitted Investments) previously made
        (and treated as a Restricted Payment) by the Company or any Restricted
        Subsidiary in such Person or Unrestricted Subsidiary, such excess shall
        not be included in this clause (E) unless the amount represented by such
        excess has not been and will not be taken into account in one of the
        foregoing clauses (A)-(D); plus

             (F) $15.0 million.

     (b) The preceding provisions will not prohibit:

          (1) any Restricted Payment made out of the Net Cash Proceeds of the
     substantially concurrent issuance or sale of, or made by conversion into or
     exchange for, Capital Stock of the Company (other than Disqualified Stock
     and other than Capital Stock issued or sold to a Subsidiary of the Company
     or an employee stock ownership plan or to a trust established by the
     Company or any of its Subsidiaries for the benefit of their employees) or a
     substantially concurrent cash capital contribution received by the Company
     from one or more of its shareholders; provided, however, that (A) such
     Restricted Payment shall be excluded in the calculation of the amount of
     Restricted Payments and (B) the Net Cash Proceeds from such sale or such
     cash capital contribution (to the extent so used for such Restricted
     Payment) shall be excluded from the calculation of amounts under clause
     (3)(B) of paragraph (a) above;

          (2) any purchase, repurchase, redemption, defeasance or other
     acquisition or retirement for value of Subordinated Obligations of the
     Company or a Subsidiary Guarantor made by exchange for, or out of the
     proceeds of the substantially concurrent Incurrence or sale of,
     Indebtedness which is permitted to be Incurred pursuant to the covenant
     described under "-- Limitation on Indebtedness;" provided, however, that
     such purchase, repurchase, redemption, defeasance or other acquisition or
     retirement for value shall be excluded in the calculation of the amount of
     Restricted Payments;

          (3) any purchase, repurchase, redemption, defeasance or other
     acquisition or retirement for value of Disqualified Stock of the Company or
     a Subsidiary Guarantor made by conversion into or exchange for, or out of
     the proceeds of the substantially concurrent issuance or sale (other than
     to a Subsidiary of the Company or an employee stock ownership plan or to a
     trust established by the Company or any of its Subsidiaries for the benefit
     of their employees) of, Disqualified Stock of the Company which is
     permitted to be issued pursuant to the covenant described under
     "-- Limitation on Indebtedness;" provided, however, that such purchase,
     repurchase, redemption, defeasance or other acquisition or retirement for
     value shall be excluded in the calculation of the amount of Restricted
     Payments;

                                        69


          (4) dividends paid within 60 days after the date of declaration
     thereof if at such date of declaration such dividend would have complied
     with this covenant; provided, however, that at the time of payment of such
     dividend, no other Default shall have occurred and be continuing (or result
     therefrom); provided further, however, that such dividend shall be included
     in the calculation of the amount of Restricted Payments at the time of
     payment;

          (5) the purchase, redemption or other acquisition or retirement for
     value of shares of Capital Stock of the Company or any of its Subsidiaries
     from employees, former employees, directors or former directors of the
     Company or any of its Subsidiaries (or permitted transferees of such
     employees, former employees, directors or former directors), pursuant to
     the terms of the agreements (including employment agreements) or plans (or
     amendments thereto) approved by the Board of Directors under which such
     individuals purchase or sell or are granted the option to purchase or sell,
     shares of such Capital Stock; provided, however, that the aggregate amount
     of such purchases, redemptions and other acquisitions and retirements
     (excluding amounts representing cancellation of Indebtedness) shall not
     exceed $2.0 million in any calendar year; provided further, however, that
     such purchases, redemptions and other acquisitions and retirements shall be
     excluded in the calculation of the amount of Restricted Payments;

          (6) the payment of cash in lieu of fractional shares of Capital Stock
     in connection with any transaction otherwise permitted under this covenant;
     provided, however, that such payment will be excluded in the calculation of
     the amount of Restricted Payments;

          (7) so long as no Default has occurred and is continuing, the
     declaration and payment of regularly accruing dividends to holders of any
     class or series of Designated Preferred Stock of the Company issued on or
     after the Issue Date; provided, however, that at the time of the
     designation of such Preferred Stock as Designated Preferred Stock, and
     after giving effect to such designation on a pro forma basis (for purposes
     of making determinations on a pro forma basis pursuant to this clause (7),
     treating all dividends which will accrue on such Designated Preferred Stock
     during the four full fiscal quarters immediately following such issuance,
     as well as all other Designated Preferred Stock then outstanding, as if the
     same will in fact be, or have in fact been, paid in cash), the Company
     would have been able to incur at least $1.00 of additional Indebtedness
     under paragraph (a) of the covenant described under "-- Limitation on
     Indebtedness"; provided further, however, that such declaration and payment
     shall be excluded from the calculation of Restricted Payments;

          (8) so long as no Default has occurred and is continuing, any
     declaration or payment of dividends and other distributions in respect of,
     and any purchase, redemption or other acquisition or retirement for value
     of, the Existing Preferred Stock; provided, however, that such dividends,
     distributions, purchases, redemptions or other acquisitions or retirements
     for value will be excluded from the calculation of Restricted Payments;

          (9) Restricted Payments in or to the Company or any of its Restricted
     Subsidiaries; provided, however, that such Restricted Payments will be
     excluded from the calculation of Restricted Payments; or

          (10) upon the occurrence of a Change of Control or an Asset
     Disposition and within 60 days after the completion of the offer to
     repurchase the Notes pursuant to the covenants described under "-- Change
     of Control" above or "-- Limitation on Sales of Assets and Subsidiary
     Stock" below, (including the purchase of all Notes tendered), any purchase,
     repurchase, redemption, defeasance, acquisition or other retirement for
     value of Subordinated Obligations required pursuant to the terms thereof as
     a result of such Change of Control or Asset Disposition at a purchase or
     redemption price not to exceed 101% of the outstanding principal amount
     thereof, plus accrued and unpaid interest thereon, if any; provided,
     however, that (A) at the time of such purchase, repurchase, redemption,
     defeasance or other acquisition or retirement for value, no Default shall
     have occurred and be continuing (or would result therefrom), and (B) such
     purchase, repurchase redemption, defeasance or other acquisition and
     retirement for value will be excluded in the calculation of the amount of
     Restricted Payments.

                                        70


     The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the assets proposed to be
transferred by the Company or such Restricted Subsidiary, as the case may be, in
accordance with the Restricted Payment.

     For purposes of determining compliance with this covenant, in the event
that a Restricted Payment meets the criteria of more than one of the types of

order and classify such Restricted Payment in any manner in compliance with this
covenant.

  LIMITATION ON RESTRICTIONS ON DISTRIBUTIONS FROM RESTRICTED SUBSIDIARIES

     The Company will not, and will not permit any Restricted Subsidiary to,

Company or a Restricted Subsidiary or pay any Indebtedness owed to the Company,

        Incurred by such Restricted Subsidiary or Capital Stock or other
        agreement or instrument of such Restricted Subsidiary in existence on or
        prior to the date on which such Restricted Subsidiary was acquired
        (including by merger or otherwise) by the Company or otherwise becomes a
        Restricted Subsidiary (other than Indebtedness Incurred, Capital Stock
        issued or agreements or instruments entered into as consideration in, or
        to provide all or any portion of the funds or credit support utilized to

        referred to in clause (A) or (B) of clause (1) of this covenant or this
        clause (C) or clause (B) of clause (2) of this covenant; provided,
        however, that the encumbrances and restrictions with respect to such
        Restricted Subsidiary contained in any such refinancing agreement or
        amendment, modification, restatement, renewal, increase, supplement,
        replacement or extension agreement are not materially more restrictive,
        taken as a whole, than encumbrances and restrictions with respect to
        such Restricted Subsidiary contained in such predecessor agreements;

             (D) any customary restriction with respect to a Restricted
        Subsidiary imposed pursuant to a merger agreement or an agreement
        entered into for the sale or disposition of the Capital Stock or assets
        of such Restricted Subsidiary pending the closing of such sale or

        Subsidiaries; and

                                        71


          (2) with respect to clause (c) only,

             (A) any such encumbrance or restriction consisting of customary
        nonassignment provisions (including provisions forbidding subletting or
        sublicensing) in leases governing leasehold interests and licenses to
        the extent such provisions restrict the transfer of the lease or license
        or the property leased or licensed thereunder;

             (B) encumbrances and restrictions contained in any agreement,
        instrument or Capital Stock assumed by the Company or any of its

        agreement, instrument or Capital Stock was entered into in connection
        with or in contemplation of such transaction), which encumbrances and

        under contracts entered into in the ordinary course of business;

             (E) encumbrances and restrictions contained in contracts entered
        into in the ordinary course of business, not relating to any
        Indebtedness, and that do not, individually or in the aggregate, detract
        from the value of, or from the ability of the Company and the Restricted
        Subsidiaries to realize the value of, property or assets of the Company
        or any Restricted Subsidiary in any manner material to the Company or
        any Restricted Subsidiary; and (F) restrictions on the transfer of
        property or assets required by any regulatory authority having
        jurisdiction over the Company or such Restricted Subsidiary.

directly or indirectly, create, incur, assume or suffer to exist or become
effective any Lien securing Indebtedness of any kind except for Permitted Liens,
on or with respect to any of its assets, whether owned at the Issue Date or
thereafter acquired, unless (A) in the case of any Lien securing Subordinated
Obligations, the notes are secured by a Lien on such assets that is senior in
priority to such Lien and (B) in the case of any other Lien, the notes are
either secured equally and ratably with such Indebtedness or are secured by a
Lien on such assets that is senior in priority to such Lien.

  LIMITATION ON SALES OF ASSETS AND SUBSIDIARY STOCK

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, consummate any Asset Disposition unless:

          (1) the Company or such Restricted Subsidiary receives consideration
     at the time of such Asset Disposition at least equal to the fair market
     value (as determined in good faith by the Board of Directors, an Officer or
     an officer of such Restricted Subsidiary with responsibility for such
     transaction, which determination shall be conclusive evidence of compliance
     with this provision) of the shares or assets subject to such Asset
     Disposition;

          (2) in the case of an Asset Disposition in excess of $5.0 million, at
     least 75% of the consideration thereof received by the Company or such
     Restricted Subsidiary is in the form of cash, cash equivalents, oil and
     natural gas properties or capital assets to be used by the Company or any
     Restricted Subsidiary in the Oil and Gas Business; and

          (3) an amount equal to 100% of the Net Available Cash from such Asset
     Disposition is applied by the Company (or such Restricted Subsidiary, as
     the case may be)
                                        72


             (A) first, to the extent the Company so elects, to prepay, repay,
        purchase, repurchase, redeem, defease or otherwise acquire or retire for
        value Senior Indebtedness of the Company or any Subsidiary Guarantor or
        Indebtedness of a Wholly Owned Subsidiary that is not a Subsidiary
        Guarantor (in each case other than Indebtedness owed to the Company or
        an Affiliate of the Company) within one year from the later of the date
        of such Asset Disposition or the receipt of such Net Available Cash;

             (B) second, to the extent of the balance of such Net Available Cash
        after application in accordance with clause (A), to the extent the
        Company so elects, to acquire Additional Assets or make capital
        expenditures in the Oil and Gas Business within one year from the later
        of the date of such Asset Disposition or the receipt of such Net
        Available Cash; and

             (C) third, to the extent of the balance of such Net Available Cash
        after application in accordance with clauses (A) and (B), to make an
        offer to the holders of the notes (and to holders of other Senior
        Subordinated Indebtedness of the Company designated by the Company) to
        purchase notes (and such other Senior Subordinated Indebtedness of the
        Company) pursuant to and subject to the conditions contained in the
        Indenture;

     provided, however, that in connection with any prepayment, repayment,
purchase, repurchase, redemption, defeasance or other acquisition or retirement
for value of Indebtedness pursuant to clause (A) or (C) above, the Company or
such Restricted Subsidiary shall permanently retire such Indebtedness and shall
cause the related loan commitment (if any) to be permanently reduced in an
amount equal to the principal amount so prepaid, repaid or purchased.

     Notwithstanding the foregoing provisions of this covenant, the Company and
the Restricted Subsidiaries will not be required to apply any Net Available Cash
in accordance with this covenant except to the extent that the aggregate Net
Available Cash from all Asset Dispositions which is not applied in accordance
with this covenant exceeds $20 million. Pending application of Net Available
Cash pursuant to this covenant, such Net Available Cash shall be invested in
Temporary Cash Investments or applied to temporarily reduce revolving credit
indebtedness.

     For the purposes of paragraph (a)(2) above, the following are deemed to be
cash or cash equivalents:

          (1) the release of, pursuant to a novation or other agreement, or the
     discharge of, the Company or such Restricted Subsidiary from all liability
     on Indebtedness in connection with such Asset Disposition; and

          (2) securities received by the Company or any Restricted Subsidiary
     from the transferee that are promptly converted by the Company or such
     Restricted Subsidiary into cash.

     Notwithstanding the foregoing, the 75% limitation referred to in paragraph
(a)(2) above shall be deemed satisfied with respect to any Asset Disposition in
which the cash or cash equivalents portion of the consideration received
therefrom, determined in accordance with the foregoing provision on an after-tax
basis, is equal to or greater than what the after-tax proceeds would have been
had such Asset Disposition complied with the aforementioned 75% limitation.

     The requirement of clause (a)(3)(B) above shall be deemed to be satisfied
if an agreement (including a lease, whether a capital lease or an operating
lease) committing to make the acquisitions or expenditures referred to therein
is entered into by the Company or its Restricted Subsidiary within the time
period specified in such clause and such Net Available Cash is subsequently
applied in accordance with such agreement within six months following such
agreement.

     (b) In the event of an Asset Disposition that requires the purchase of
notes (and other Senior Subordinated Indebtedness of the Company) pursuant to
clause (a)(3)(C) above, the Company will make such offer to purchase notes on or
before the 366th day after the later of the date of such Asset Disposition or
the receipt of such Net Available Cash, and will purchase notes tendered
pursuant to an offer by the Company for the notes (and such other Senior
Subordinated Indebtedness of the Company) at a purchase price of 100% of their
principal amount (or, in the event such other Senior Subordinated Indebtedness
of the Company was
                                        73


issued with significant original issue discount, 100% of the accreted value
thereof) without premium, plus accrued but unpaid interest (or, in respect of
such other Senior Subordinated Indebtedness of the Company, such lesser price,
if any, as may be provided for by the terms of such Senior Subordinated
Indebtedness of the Company) in accordance with the procedures (including
prorating in the event of oversubscription) set forth in the Indenture. If the
aggregate purchase price of the notes and any other Senior Subordinated
Indebtedness tendered exceeds the Net Available Cash allotted to their purchase,
the Company will select the notes and other Senior Subordinated Indebtedness to
be purchased on a pro rata basis but in round denominations, which in the case
of the notes will be denominations of $1,000 principal amount or multiples
thereof. The Company shall not be required to make such an offer to purchase
notes (and other Senior Subordinated Indebtedness of the Company) pursuant to
this covenant if the Net Available Cash available therefor is less than $20
million (which lesser amount shall be carried forward for purposes of
determining whether such an offer is required with respect to the Net Available
Cash from any subsequent Asset Disposition).

     (c) The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Company will comply
with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under this covenant by virtue of its compliance
with such securities laws or regulations.

  LIMITATION ON AFFILIATE TRANSACTIONS

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
enter into any transaction (including the purchase, sale, lease or exchange of
any property, employee compensation arrangements or the rendering of any
service) with, or for the benefit of, any Affiliate of the Company (an
"Affiliate Transaction") unless:

          (1) the terms of the Affiliate Transaction are no less favorable to
     the Company or such Restricted Subsidiary than those that could reasonably
     be expected to be obtained at the time of the Affiliate Transaction in
     arm's-length dealings with a Person who is not an Affiliate;

          (2) if such Affiliate Transaction involves an amount in excess of $15
     million, the terms of the Affiliate Transaction are set forth in writing
     and a majority of the non-employee directors of the Company disinterested
     with respect to such Affiliate Transaction shall have determined in good
     faith that the criteria set forth in clause (1) are satisfied and shall
     have approved the relevant Affiliate Transaction as evidenced by a
     resolution of the Board of Directors; and

          (3) if such Affiliate Transaction involves an amount in excess of $30
     million, the Board of Directors shall have received a written opinion from
     an Independent Qualified Party to the effect that such Affiliate
     Transaction is fair, from a financial standpoint, to the Company and its
     Restricted Subsidiaries or is not less favorable to the Company and its
     Restricted Subsidiaries than could reasonably be expected to be obtained at
     the time in an arm's-length transaction with a Person who was not an
     Affiliate.

     (b) The provisions of the preceding paragraph (a) will not prohibit:

          (1) any Investment (other than a Permitted Investment) or other
     Restricted Payment, in each case not prohibited to be made pursuant to the
     covenant described under "-- Limitation on Restricted Payments;"

          (2) any issuance of securities, or other payments, awards or grants in
     cash, securities or otherwise pursuant to, or the funding of, employment
     arrangements, stock options and stock ownership plans and other benefit
     plans approved by the Board of Directors;

          (3) loans or advances to officers, directors and employees in the
     ordinary course of business of the Company or its Restricted Subsidiaries,
     but in any event not to exceed $3.0 million in the aggregate outstanding at
     any one time;

                                        74


          (4) any transaction between or among the Company, a Restricted
     Subsidiary or joint venture or other Person that would constitute an
     Affiliate Transaction solely because the Company or a Restricted Subsidiary
     owns an equity interest in or otherwise controls such Restricted
     Subsidiary, joint venture or other Person;

          (5) the issuance or sale of any Capital Stock (other than Disqualified
     Stock) of the Company;

          (6) reasonable fees and reasonable compensation paid to, and indemnity
     and similar arrangements provided on behalf of, officers, directors and
     employees of the Company or any Restricted Subsidiary as determined in good
     faith by the Board of Directors or the Company's senior management; and

          (7) with respect to any agreements or arrangements in effect on, or
     entered into on or prior to, the Issue Date, and which are disclosed in the
     Offering Circular dated October 31, 2001, any amendment, modification, or
     supplement thereto or any replacement thereof, so long as any such
     amendment, modification, supplement or replacement agreement or arrangement
     is not materially more disadvantageous to the holders of the Notes than the
     original agreements and arrangements as in effect on the Issue Date, and
     any transactions contemplated by any of the foregoing agreements or
     arrangements.

  MERGER AND CONSOLIDATION

     The Company will not consolidate with or merge with or into, or convey,
transfer or lease, in one transaction or a series of transactions, directly or
indirectly, all or substantially all the assets of the Company and its
Restricted Subsidiaries, taken as a whole, to, any Person, unless:

          (1) the resulting, surviving or transferee Person (the "Successor
     Company") shall be a Person organized and existing under the laws of the
     United States of America, any State thereof or the District of Columbia and
     the Successor Company (if not the Company) shall expressly assume, by an
     indenture supplemental thereto, executed and delivered to the Trustee, in
     form satisfactory to the Trustee, all the obligations of the Company under
     the notes and the Indenture;

          (2) immediately after giving pro forma effect to such transaction (and
     treating any Indebtedness which becomes an obligation of the Successor
     Company or any Subsidiary as a result of such transaction as having been
     Incurred by such Successor Company or such Subsidiary at the time of such
     transaction), no Default shall have occurred and be continuing;

          (3) immediately after giving pro forma effect to such transaction, the
     Successor Company would be able to Incur an additional $1.00 of
     Indebtedness pursuant to paragraph (a) of the covenant described under
     "-- Limitation on Indebtedness;"

          (4) the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that such
     consolidation, merger, conveyance, transfer or lease and such supplemental
     indenture (if any) comply with the Indenture; and

          (5) the Company shall have delivered to the Trustee an Opinion of
     Counsel to the effect that the holders will not recognize income, gain or
     loss for Federal income tax purposes as a result of such transaction and
     will be subject to Federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such
     transaction had not occurred;

provided, however, that clause (3) will not be applicable (A) to the Company or
a Restricted Subsidiary consolidating with, merging into, conveying,
transferring or leasing all or part of its assets to the Company or a Subsidiary
Guarantor, (B) to the Company merging with an Affiliate of the Company solely
for the purpose and with the sole effect of reincorporating the Company in
another jurisdiction within the United States of America or (C) at any time when
the Company and its Restricted Subsidiaries are not subject to the Suspended
Covenants.

     The Successor Company (if not the Company) will be the successor to the
Company and shall succeed to, and be substituted for, and may exercise every
right and power of, the Company under the Indenture, and

                                        75


the predecessor Company, except in the case of a lease, shall be released from
the obligation to pay the principal of and interest on the notes.

     The Company will not permit any Subsidiary Guarantor to consolidate with or
merge with or into, or convey, transfer or lease, in one transaction or a series
of transactions, all or substantially all of its assets to any Person unless:

          (1) (other than in the case of a Subsidiary Guarantor that has been
     disposed of in its entirety to another Person (other than to the Company or
     an Affiliate of the Company), whether through a merger, consolidation or
     sale of Capital Stock or assets, if in connection therewith the Company
     complies with its obligations under the covenant described under
     "-- Limitation on Sales of Assets and Subsidiary Stock" in respect of such
     disposition), the resulting, surviving or transferee Person (if not such
     Subsidiary) shall be a Person organized and existing under the laws of the
     jurisdiction under which such Subsidiary was organized or under the laws of
     the United States of America, or any State thereof or the District of
     Columbia, and, if such Person is not a Subsidiary Guarantor, such Person
     shall expressly assume, by a Guaranty Agreement, in a form satisfactory to
     the Trustee, all the obligations of such Subsidiary, if any, under its
     Subsidiary Guaranty;

          (2) immediately after giving effect to such transaction or
     transactions on a pro forma basis (and treating any Indebtedness which
     becomes an obligation of the resulting, surviving or transferee Person as a
     result of such transaction as having been issued by such Person at the time
     of such transaction), no Default shall have occurred and be continuing; and

          (3) in the event a Guaranty Agreement is executed and delivered
     pursuant to clause (1) above, the Company delivers to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each stating that such
     consolidation, merger, conveyance, transfer or lease and such Guaranty
     Agreement comply with the Indenture.

  FUTURE GUARANTORS

     The Company will cause each Restricted Subsidiary that Incurs any
Indebtedness (other than Indebtedness Incurred pursuant to and in compliance
with the last clause of paragraph (b)(16) of the covenant described under
"-- Limitation on Indebtedness") to, at the same time, execute and deliver to
the Trustee a Guaranty Agreement pursuant to which such Restricted Subsidiary
will Guarantee payment of the notes on the same terms and conditions as those
set forth in the Indenture.

  SEC REPORTS

     Notwithstanding that the Company may not be subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, the Company will file
with the SEC and provide the Trustee and noteholders with such annual reports
and such information, documents and other reports as are specified in Sections
13 and 15(d) of the Exchange Act and applicable to a U.S. corporation subject to
such Sections (but without exhibits in the case of noteholders), such
information, documents and other reports to be so filed and provided at the
times specified for the filings of such information, documents and reports under
such Sections.

     In addition, the Company will furnish to the holders of the notes and to
prospective investors, upon the requests of such holders, any information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so
long as the notes are not freely transferable under the Securities Act.

DEFAULTS

     Each of the following is an Event of Default:

          (1) a default in the payment of interest on the notes when due,
     continued for 30 days;

          (2) a default in the payment of principal of any note when due at its
     Stated Maturity, upon optional redemption, upon required purchase, upon
     declaration of acceleration or otherwise;

                                        76


          (3) the failure by the Company to comply with its obligations under
     "-- Certain Covenants -- Merger and Consolidation" above;

          (4) the failure by the Company to comply for 30 days after notice with
     any of its obligations in the covenants described above under "Change of
     Control" (other than a failure to purchase notes) or under "-- Certain
     Covenants" under "-- Limitation on Indebtedness," "-- Limitation on
     Restricted Payments," "-- Limitation on Restrictions on Distributions from
     Restricted Subsidiaries," "-- Limitation on Liens," "-- Limitation on Sales
     of Assets and Subsidiary Stock" (other than a failure to purchase notes),
     "-- Limitation on Affiliate Transactions," "-- Future Guarantors" or
     "-- SEC Reports;"

          (5) the failure by the Company or any Subsidiary Guarantor to comply
     for 60 days after notice with its other agreements contained in the
     Indenture;

          (6) Indebtedness of the Company or any Significant Subsidiary is not
     paid within any applicable grace period after final maturity or is
     accelerated by the holders thereof because of a default and the total
     amount of such Indebtedness unpaid or accelerated exceeds $10.0 million
     (the "cross acceleration provision");

          (7) certain events of bankruptcy, insolvency or reorganization of the
     Company or any Significant Subsidiary (the "bankruptcy provisions");

          (8) any judgment or decree for the payment of money in excess of $10.0
     million above the coverage under applicable insurance policies and
     indemnities as to which the relevant insurer or indemnitor has not
     disclaimed responsibility is entered against the Company or any Significant
     Subsidiary, remains outstanding for a period of 60 consecutive days
     following such judgment and is not discharged, waived or stayed (the
     "judgment default provision"); or

          (9) a Subsidiary Guaranty ceases to be in full force and effect (other
     than in accordance with the terms of such Subsidiary Guaranty) for five
     days after notice or any Subsidiary Guarantor denies or disaffirms its
     obligations under its Subsidiary Guaranty other than in accordance with the
     terms of such Subsidiary Guaranty (the "Guarantor failure provision").

However, a default under clauses (4), (5) and (9) will not constitute an Event
of Default until the Trustee or the holders of at least 25% in principal amount
of the outstanding notes notify the Company of the default and the Company does
not cure such default within the time specified after receipt of such notice.

     If an Event of Default occurs and is continuing, the Trustee or the holders
of at least 25% in principal amount of the outstanding notes may declare the
principal of and accrued but unpaid interest on all the notes to be due and
payable. Upon such a declaration, such principal and interest shall be due and
payable immediately. If an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization of the Company occurs and is
continuing, the principal of and interest on all the notes will ipso facto
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any holders of the notes. Under certain
circumstances, the holders of a majority in principal amount of the outstanding
notes may rescind any such acceleration with respect to the notes and its
consequences.

     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the holders of the notes unless
such holders have offered to the Trustee reasonable indemnity or security
against any loss, liability or expense. Except to enforce the right to receive
payment of principal, premium (if any) or interest when due, no holder of a note
may pursue any remedy with respect to the Indenture or the notes unless:

          (1) such holder has previously given the Trustee notice that an Event
     of Default is continuing;

          (2) holders of at least 25% in principal amount of the outstanding
     notes have requested the Trustee to pursue the remedy;

          (3) such holders have offered the Trustee security or indemnity
     satisfactory to it against any loss, liability or expense;
                                        77


          (4) the Trustee has not complied with such request within 60 days
     after the receipt thereof and the offer of security or indemnity; and

          (5) holders of a majority in principal amount of the outstanding notes
     have not given the Trustee a direction inconsistent with such request
     within such 60-day period.

Subject to certain restrictions, the holders of a majority in principal amount
of the outstanding notes are given the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. The Trustee, however,
may refuse to follow any direction that conflicts with law or the Indenture or
that the Trustee determines is unduly prejudicial to the rights of any other
holder of a note or that would involve the Trustee in personal liability.

     If a Default occurs, is continuing and is known to the Trustee, the Trustee
must mail to each holder of the notes notice of the Default within 90 days after
it occurs (and such notice must specify that it is a notice of default under the
Indenture). Except in the case of a Default in the payment of principal of or
interest on any note, the Trustee may withhold notice if and so long as a
committee of its Trust Officers determines that withholding notice is not
opposed to the interest of the holders of the notes. In addition, we are
required to deliver to the Trustee, within 120 days after the end of each fiscal
year, a certificate indicating whether the signers thereof know of any Default
that occurred during the previous year. We are required to deliver to the
Trustee, within 30 days after the occurrence thereof, written notice of any
event which would constitute certain Defaults, their status and what action we
are taking or propose to take in respect thereof.

AMENDMENTS AND WAIVERS

     Subject to certain exceptions, the Indenture may be amended with the
consent of the holders of a majority in principal amount of the notes then
outstanding (including consents obtained in connection with a tender offer or
exchange for the notes) and any past default or compliance with any provisions
may also be waived with the consent of the holders of a majority in principal
amount of the notes then outstanding. However, without the consent of each
holder of an outstanding note affected thereby, an amendment or waiver may not,
among other things:

          (1) reduce the amount of notes whose holders must consent to an
     amendment;

          (2) reduce the rate of or extend the time for payment of interest on
     any note;

          (3) reduce the principal of or extend the Stated Maturity of any note;

          (4) reduce the amount payable upon the redemption of any note or
     change the time at which any note may be redeemed as described under
     "-- Optional Redemption;"

          (5) make any note payable in money other than that stated in the note;

          (6) impair the right of any holder of the notes to receive payment of
     principal of and interest on such holder's notes on or after the due dates
     therefor or to institute suit for the enforcement of any payment on or with
     respect to such holder's notes;

          (7) make any change in the provisions which require each affected
     holder's consent to an amendment or waiver;

          (8) make any change in the ranking or priority of any note that would
     adversely affect the noteholders; or

          (9) make any change in any Subsidiary Guaranty that would adversely
     affect the noteholders in any material respect.

     Notwithstanding the preceding, the covenant described under the caption "--
Change of Control" may be amended as described in the last paragraph of that
description.

                                        78


     Notwithstanding the preceding, without the consent of any holder of the
notes, the Company, the Subsidiary Guarantors and Trustee may amend the
Indenture:

          (1) to cure any ambiguity, omission, defect or inconsistency;

          (2) to provide for the assumption by a successor corporation of the
     obligations of the Company or any Subsidiary Guarantor under the Indenture;

          (3) to provide for uncertificated notes in addition to or in place of
     certificated notes (provided that the uncertificated notes are issued in
     registered form for purposes of Section 163(f) of the Code, or in a manner
     such that the uncertificated notes are described in Section 163(f)(2)(B) of
     the Code);

          (4) to eliminate the subordination provisions contained therein and
     add covenants relating to Liens and Sale/Leaseback Transactions described
     under "Certain Covenants -- Covenant Suspension;"

          (5) to add guarantees with respect to the notes, including any
     Subsidiary Guaranties, or to secure the notes;

          (6) to add to the covenants of the Company or any Subsidiary Guarantor
     for the benefit of the holders of the notes or to surrender any right or
     power conferred upon the Company or any Subsidiary Guarantor;

          (7) to make any change that does not adversely affect the rights of
     any holder of the notes; or

          (8) to comply with any requirement of the SEC in connection with the
     qualification of the Indenture under the Trust Indenture Act.

     Except as is specified in clause (4) above, no amendment may be made to the
subordination provisions of the Indenture that adversely affects the rights of
any holder of Senior Indebtedness of the Company or of a Subsidiary Guarantor
then outstanding unless such holder of such Senior Indebtedness (or its
Representative) consents to such change or as otherwise permitted by the notes,
debentures, bonds or other similar instruments evidencing such Senior
Indebtedness.

     The consent of the holders of the notes is not necessary under the
Indenture to approve the particular form of any proposed amendment. It is
sufficient if such consent approves the substance of the proposed amendment.

     After an amendment under the Indenture becomes effective, we are required
to mail to holders of the notes a notice briefly describing such amendment.
However, the failure to give such notice to all holders of the notes, or any
defect therein, will not impair or affect the validity of the amendment.

TRANSFER

     The notes will be issued in registered form and will be transferable only
upon the surrender of the notes being transferred for registration of transfer.
We may require payment of a sum sufficient to cover any tax, assessment or other
governmental charge payable in connection with certain transfers and exchanges.

DEFEASANCE

     At any time, we may terminate all our obligations under the notes and the
Indenture ("legal defeasance"), except for certain obligations, including those
respecting the defeasance trust and obligations to register the transfer or
exchange of the notes, to replace mutilated, destroyed, lost or stolen notes and
to maintain a registrar and paying agent in respect of the notes.

     In addition, at any time we may terminate the subordination provisions
described above under "Ranking" and our obligations under "-- Change of Control"
and under the covenants described under "-- Certain Covenants" (other than the
covenant described under "-- Merger and Consolidation"), the operation of the
cross acceleration provision, the bankruptcy provisions with respect to
Significant Subsidiaries, the judgment default and Guarantor failure provisions
described under "-- Defaults" above and the limitation contained in

                                        79


clause (3) of the first paragraph under "-- Certain Covenants -- Merger and
Consolidation" above ("covenant defeasance").

     We may exercise our legal defeasance option notwithstanding our prior
exercise of our covenant defeasance option. If we exercise our legal defeasance
option, payment of the notes may not be accelerated because of an Event of
Default with respect thereto. If we exercise our covenant defeasance option,
payment of the notes may not be accelerated because of an Event of Default
specified in clause (4), (6), (7) (with respect only to Significant
Subsidiaries), (8) or (9) under "-- Defaults" above or because of the failure of
the Company to comply with clause (3) of the first paragraph under "-- Certain
Covenants -- Merger and Consolidation" above. If we exercise our legal
defeasance option or our covenant defeasance option, each Subsidiary Guarantor
will be released from all of its obligations with respect to its Subsidiary
Guaranty.

     In order to exercise either of our defeasance options, we must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal and interest on the notes to
redemption or maturity, as the case may be, and must comply with certain other
conditions, including delivery to the Trustee of an Opinion of Counsel to the
effect that holders of the notes will not recognize income, gain or loss for
Federal income tax purposes as a result of such deposit and defeasance and will
be subject to Federal income tax on the same amounts and in the same manner and
at the same times as would have been the case if such deposit and defeasance had
not occurred (and, in the case of legal defeasance only, such Opinion of Counsel
must be based on a ruling of the Internal Revenue Service or other change in
applicable Federal income tax law).

CONCERNING THE TRUSTEE

     The Bank of New York is the Trustee under the Indenture and Registrar and
Paying Agent with regard to the notes.

     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; provided, however, if it acquires any conflicting interest it must
either eliminate such conflict within 90 days, apply to the SEC for permission
to continue or resign. The Bank of New York is currently a lender under the
Replacement Credit Facility and we are currently in compliance with the terms of
the Indebtedness owed by us to The Bank of New York under the Replacement Credit
Facility.

     The holders of a majority in principal amount of the outstanding notes will
have the right to direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee, subject to certain
exceptions. If an Event of Default occurs (and is not cured), the Trustee will
be required, in the exercise of its power, to use the degree of care of a
prudent man in the conduct of his own affairs. Subject to such provisions, the
Trustee will be under no obligation to exercise any of its rights or powers
under the Indenture at the request of any holder of notes unless such holder
shall have offered to the Trustee security and indemnity satisfactory to it
against any loss, liability or expense and then only to the extent required by
the terms of the Indenture.

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     No director, officer, employee, incorporator or stockholder of the Company
or any Subsidiary Guarantor will have any liability for any obligations of the
Company or any Subsidiary Guarantor under the notes, any Subsidiary Guaranty or
the Indenture or for any claim based on, in respect of, or by reason of such
obligations or their creation. Each Holder of the notes by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the notes. Such waiver and release may not be
effective to waive liabilities under the U.S. federal securities laws, and it is
the view of the SEC that such a waiver is against public policy.

                                        80


GOVERNING LAW

     The Indenture is, and the exchange notes will be, governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflicts of law to the extent that the
application of the law of another jurisdiction would be required thereby.

CERTAIN DEFINITIONS

     another Restricted Subsidiary; or

          (3) Capital Stock constituting a minority interest in any Person that
     at such time is a Restricted Subsidiary;

provided, however, that any such Restricted Subsidiary described in clause (2)
or (3) above is primarily engaged in a Related Business.

duplication), as of the date of determination:

          (a) the sum of:

        gas reserves of the Company and its Restricted Subsidiaries calculated
        in accordance with SEC guidelines before any state or federal income
        taxes, as estimated in a reserve report prepared as of the end of the
        fiscal year ending at least 45 days prior to the date of determination
        (or for the period prior to the earlier of April 1, 2002 and the date
        the reserve report for 2001 is available, as of June 30, 2001), which
        reserve report is prepared or audited by independent petroleum
        engineers, as increased by, as of the date of determination, the
        discounted future net revenue of:

                (A) estimated proved crude oil and natural gas reserves of the
           Company and its Restricted Subsidiaries attributable to acquisitions
           consummated since the date of such reserve report, and

                (B) estimated crude oil and natural gas reserves of the Company
           and its Restricted Subsidiaries attributable to extensions,
           discoveries and other additions and upward determinations of
           estimates of proved crude oil and natural gas reserves (including
           previously estimated development costs incurred during the period and
           the accretion of discount since the prior period end) due to
           exploration, development or exploitation, production or other
           activities which reserves were not reflected in such reserve report
           which would, in accordance with standard industry practice, result in
           such determinations, in each case calculated in accordance with SEC
           guidelines (utilizing the prices utilized in such year-end reserve
           report),

               and decreased by, as of the date of determination, the discounted
               future net revenue attributable to:

                (C) estimated proved crude oil and natural gas reserves of the
           Company and its Restricted Subsidiaries reflected in such reserve
           report produced or disposed of since the date of such reserve report,
           and

                (D) reductions in the estimated oil and natural gas reserves of
           the Company and its Restricted Subsidiaries reflected in such reserve
           report since the date of such reserve report attributable to downward
           determinations of estimates of proved crude oil and natural gas
           reserves due to exploration, development or exploitation, production
           or other activities conducted or otherwise occurring since the date
           of such reserve report which would, in accordance

                                        81


           with standard industry practice, result in such determinations, in
           each case calculated in accordance with SEC guidelines (utilizing the
           prices utilized in such reserve report);

                provided, however, that, in the case of each of the
           determinations made pursuant to clauses (A) through (D), such
           increases and decreases shall be estimated by the Company's
           engineers, except that if as a result of such acquisitions,
           dispositions, discoveries, extensions or revisions, there is a
           Material Change, then such increases and decreases in the discounted
           future net revenue shall be confirmed in writing by an independent
           petroleum engineer;

             (2) the capitalized costs that are attributable to crude oil and
        natural gas properties of the Company and its Restricted Subsidiaries to
        which no proved crude oil and natural gas reserves are attributed, based
        on the Company's books and records as of a date no earlier than the most
        recent fiscal quarter ending at least 45 days prior to the date of
        determination;

             (3) the Net Working Capital as of the end of the most recent fiscal
        quarter ending at least 45 days prior to the date of determination; and

             (4) the greater of (i) the net book value as of a date no earlier
        than the most recent fiscal quarter ending at least 45 days prior to the
        date of determination and (ii) the appraised value, as estimated by
        independent appraisers, of other tangible assets of the Company and its
        Restricted Subsidiaries as of a date no earlier than the most recent
        fiscal year ending at least 45 days prior to the date of determination
        (provided that the Company shall not be required to obtain such an
        appraisal of such assets if no such appraisal has been performed); minus

          (b) to the extent not otherwise taken into account in the immediately
     preceding clause (a), the sum of:

             (1) minority interests;

             (2) any natural gas balancing liabilities of the Company and its
        Restricted Subsidiaries reflected in the Company's latest audited
        financial statements;

             (3) the discounted future net revenue, calculated in accordance
        with SEC guidelines (utilizing the same prices utilized in the Company's
        year-end reserve report), attributable to reserves subject to
        participation interests, overriding royalty interests or other interests
        of third parties, pursuant to participation, partnership, vendor
        financing or other agreements then in effect, or which otherwise are
        required to be delivered to third parties;

             (4) the discounted future net revenue calculated in accordance with
        SEC guidelines (utilizing the same prices utilized in the Company's
        year-end reserve report), attributable to reserves that are required to
        be delivered to third parties to fully satisfy the obligations of the
        Company and its Restricted Subsidiaries with respect to Volumetric
        Production Payments on the schedules specified with respect thereto; and

             (5) the discounted future net revenue, calculated in accordance
        with SEC guidelines, attributable to reserves subject to
        Dollar-Denominated Production Payments that, based on the estimates of
        production included in determining the discounted future net revenue
        specified in the immediately preceding clause (a)(1) (utilizing the same
        prices utilized in the Company's year-end reserve report), would be
        necessary to satisfy fully the obligations of the Company and its
        Restricted Subsidiaries with respect to Dollar-Denominated Production
        Payments on the schedules specified with respect thereto.

     If the Company changes its method of accounting from the successful efforts
method to the full cost method or a similar method of accounting, "ACNTA" will
continue to be calculated as if the Company were still using the successful
efforts method of accounting.

     "Affiliate" of any specified Person means any other Person, directly or
indirectly, controlling or controlled by or under direct or indirect common
control with such specified Person. For the purposes of this definition,
"control" when used with respect to any Person means the power to direct the

the ownership of voting securities, by contract or
                                        82


otherwise; and the terms "controlling" and "controlled" have meanings
correlative to the foregoing. For purposes of the covenants described under
"-- Certain Covenants -- Limitation on Restricted Payments," "-- Certain
Covenants -- Limitation on Affiliate Transactions" and "-- Certain
Covenants -- Limitation on Sales of Assets and Subsidiary Stock" only,
"Affiliate" shall also mean any beneficial owner of Capital Stock representing
10% or more of the total voting power of the Voting Stock (on a fully diluted
basis) of the Company or of rights or warrants to purchase such Capital Stock
(whether or not currently exercisable). No Person shall be deemed an Affiliate
of an oil and natural gas royalty trust solely by virtue of ownership of units
of beneficial interest in such trust.

     "Applicable Premium" means, with respect to a note at any time, the greater
of (1) 1.0% of the principal amount of such note at such time and (2) the excess
of (A) the present value at such time of the principal amount of such note plus
any required interest payments due on such note through November 1, 2006,
computed using a discount rate equal to the Treasury Rate plus 50 basis points,
over (B) the principal amount of such note.

     "Asset Disposition" means any sale, lease, issuance, transfer or other
disposition (or series of related sales, leases, issuances, transfers or
dispositions) by the Company or any Restricted Subsidiary, including any
disposition by means of a merger, consolidation or similar transaction (each
referred to for the purposes of this definition as a "disposition"), of:

          (1) any shares of Capital Stock of a Restricted Subsidiary (other than
     directors' qualifying shares or shares required by applicable law to be
     held by a Person other than the Company or a Restricted Subsidiary);

          (2) all or substantially all the assets of any division or line of
     business of the Company or any Restricted Subsidiary; or

          (3) any other assets of the Company or any Restricted Subsidiary
     outside of the ordinary course of business of the Company or such
     Restricted Subsidiary.

          Notwithstanding the foregoing, the following shall be deemed not to be
     Asset Dispositions:

             (A) a disposition by the Company or a Restricted Subsidiary to the
        Company or a Restricted Subsidiary;

             (B) for purposes of the covenant described under "-- Certain
        Covenants -- Limitation on Sales of Assets and Subsidiary Stock" only, a
        disposition that constitutes a Restricted Payment permitted by the
        covenant described under "-- Certain Covenants -- Limitation on
        Restricted Payments" or a Permitted Investment;

             (C) a disposition of all or substantially all the assets of the
        Company in accordance with the covenant described under "-- Certain
        Covenants -- Merger and Consolidation;"

             (D) the trade or exchange by the Company or any Restricted
        Subsidiary of any oil or natural gas property or interest therein of the
        Company or such Restricted Subsidiary for any oil or natural gas
        property or interest therein of another Person, including any cash or
        cash equivalents necessary in order to achieve an exchange of equivalent
        value; provided, however, that the value of the oil or natural gas
        property or interest therein received by the Company or any Restricted
        Subsidiary in such trade or exchange (including any cash or cash
        equivalents) is at least equal to the fair market value (as determined
        in good faith by the Board of Directors, an Officer or an officer of
        such Restricted Subsidiary with responsibility for such transaction,
        which determination shall be conclusive evidence of compliance with this
        provision) of the oil or natural gas property or interest therein
        (including any cash or cash equivalents) so traded or exchanged;

             (E) the creation of a Lien;

             (F) a disposition of oil and natural gas properties in connection
        with tax credit transactions complying with Section 29 or any successor

        Unrestricted Subsidiary;

             (H) surrender or waiver of contract rights or the settlement,
        release or surrender of contract, tort or other claims of any kind;

             (I) any disposition of defaulted receivables that arose in the
        ordinary course of business for collection; and

             (J) a disposition of assets with a fair market value of less than
        $1.0 million.

     "Attributable Debt" in respect of a Sale/Leaseback Transaction means, as at
the time of determination, the present value (discounted at the interest rate
borne by the notes, compounded semi-annually) of the total obligations of the
lessee for rental payments during the remaining term of the lease included in
such Sale/ Leaseback Transaction (including any period for which such lease has
been extended); provided, however, that if such Sale/Leaseback Transaction
results in a Capital Lease Obligation, the amount of Indebtedness represented
thereby will be determined in accordance with the definition of "Capital Lease
Obligation."

     "Average Life" means, as of the date of determination, with respect to any
Indebtedness, the quotient obtained by dividing:

          (1) the sum of the products of the numbers of years from the date of
     determination to the dates of each successive scheduled principal payment
     of or redemption or similar payment with respect to such Indebtedness
     multiplied by the amount of such payment by

          (2) the sum of all such payments.

     "Bank Indebtedness" means all obligations pursuant to any Credit
Facilities.

     "Board of Directors" means the board of directors of the Company or any
committee thereof duly authorized to act on behalf of such board.

     "Business Day" means each day which is not a Legal Holiday.

     "Capital Lease Obligation" means an obligation that is required to be
classified and accounted for as a capital lease for financial reporting purposes
in accordance with GAAP, and the amount of Indebtedness represented by such
obligation shall be the capitalized amount of such obligation determined in
accordance with GAAP; and the Stated Maturity thereof shall be the date of the
last payment of rent or any other amount due under such lease prior to the first
date upon which such lease may be terminated by the lessee without payment of a
penalty.

     "Capital Stock" of any Person means any and all shares, interests, rights
to purchase, warrants, options, participations or other equivalents of or
interests in (however designated) equity of such Person, including any Preferred
Stock, but excluding any debt securities convertible into such equity.

     "Code" means the Internal Revenue Code of 1986, as amended.

     "Consolidated Coverage Ratio" as of any date of determination means the
ratio of (x) the aggregate amount of EBITDA for the period of the most recent
four consecutive fiscal quarters ending at least 45 days prior to the date of
such determination to (y) Consolidated Interest Expense for such four fiscal
quarters; provided, however, that:

          (1) if the Company or any Restricted Subsidiary has Incurred any
     Indebtedness since the beginning of such period that remains outstanding or
     if the transaction giving rise to the need to calculate the Consolidated
     Coverage Ratio is an Incurrence of Indebtedness, or both, then EBITDA and
     Consolidated Interest Expense for such period shall be calculated after
     giving effect on a pro forma basis to such Indebtedness and the use of
     proceeds thereof as if such Indebtedness had been Incurred on the first day
     of such period and such proceeds had been applied as of such date;

          (2) if the Company or any Restricted Subsidiary has repaid,
     repurchased, defeased or otherwise discharged any Indebtedness since the
     beginning of such period or if any Indebtedness is to be repaid,
     repurchased, defeased or otherwise discharged on the date of the
     transaction giving rise to the need to
                                        84


     calculate the Consolidated Coverage Ratio, then EBITDA and Consolidated
     Interest Expense for such period shall be calculated on a pro forma basis
     as if such discharge had occurred on the first day of such period and as if
     the Company or such Restricted Subsidiary had not earned the interest
     income actually earned (if any) during such period in respect of cash or
     Temporary Cash Investments used to repay, repurchase, defease or otherwise
     discharge such Indebtedness;

          (3) if, since the beginning of such period, the Company or any
     Restricted Subsidiary shall have made any Asset Disposition, then EBITDA
     for such period shall be reduced by an amount equal to EBITDA (if positive)
     directly attributable to the assets which were the subject of such Asset
     Disposition for such period, or increased by an amount equal to EBITDA (if
     negative), directly attributable thereto for such period and Consolidated
     Interest Expense for such period shall be reduced by an amount equal to the
     Consolidated Interest Expense directly attributable to any Indebtedness of
     the Company or any Restricted Subsidiary repaid, repurchased, defeased or
     otherwise discharged with respect to the Company and its continuing
     Restricted Subsidiaries in connection with such Asset Disposition for such
     period (or, if the Capital Stock of any Restricted Subsidiary is sold, the
     Consolidated Interest Expense for such period directly attributable to the
     Indebtedness of such Restricted Subsidiary to the extent the Company and
     its continuing Restricted Subsidiaries are no longer liable for such
     Indebtedness after such sale);

          (4) if, since the beginning of such period, the Company or any
     Restricted Subsidiary (by merger or otherwise) shall have made an
     Investment in any Restricted Subsidiary (or any Person which becomes a
     Restricted Subsidiary) or an acquisition of material assets, then EBITDA
     and Consolidated Interest Expense for such period shall be calculated after
     giving pro forma effect thereto (including the Incurrence of any
     Indebtedness) as if such Investment or acquisition had occurred on the
     first day of such period; and

          (5) if, since the beginning of such period, any Person (that
     subsequently became a Restricted Subsidiary or was merged with or into the
     Company or any Restricted Subsidiary since the beginning of such period)
     shall have made any Asset Disposition, any Investment or acquisition of
     assets that would have required an adjustment pursuant to clause (3) or (4)
     above if made by the Company or a Restricted Subsidiary during such period,
     then EBITDA and Consolidated Interest Expense for such period shall be
     calculated after giving pro forma effect thereto as if such Asset
     Disposition, Investment or acquisition had occurred on the first day of
     such period.

For purposes of this definition, whenever pro forma effect is to be given to an
acquisition of assets, the amount of income or earnings relating thereto and the
amount of Consolidated Interest Expense associated with any Indebtedness
Incurred in connection therewith, the pro forma calculations shall be determined
in good faith by a responsible financial or accounting Officer.

     If any Indebtedness bears a floating rate of interest and is being given
pro forma effect, the interest on such Indebtedness shall be calculated as if
the rate in effect on the date of determination had been the applicable rate for
the entire period (taking into account any Interest Rate Agreement applicable to
such Indebtedness, but if the remaining term of such Interest Rate Agreement is
less than 12 months, then such Interest Rate Agreement shall only be taken into
account for that portion of the period equal to the remaining term thereof).

     The Consolidated Interest Expense attributable to interest on any
Indebtedness under a revolving credit facility, the outstanding principal
balance of which is required to be computed on a pro forma basis in accordance
with the foregoing, shall be computed based upon the average daily balance of
such Indebtedness during the applicable period, provided, that such average
daily balance shall take into account the amount of any repayment of
Indebtedness under such revolving credit facility during the applicable period,
to the extent such repayment permanently reduced the commitments or amounts
available to be borrowed under such facility.

shall be obtained by linear interpolation (calculated to the nearest one-twelfth
of a year) from the weekly average yields of United States Treasury securities
for which such yields are given, except that if the average life to November 1,
2006 or maturity, as the case may be, of the notes is less than one year, the

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of certain of the material United States federal
income tax consequences of exchanging for, holding and selling the exchange
notes. Except where we state otherwise, this summary deals only with the
exchange notes held as capital assets, as defined in the Internal Revenue Code
of 1986, as amended, or the Code, by a United States Holder (as defined below)
who is the initial beneficial owner of the exchange notes.

     We do not address all of the tax consequences that may be relevant to a
United States Holder. We also do not address, except as stated below, any of the
tax consequences to holders that are Foreign Holders (as defined below) or to
holders that may be subject to special tax treatment including banks, thrift
institutions, real estate investment trusts, personal holding companies,
insurance companies, and brokers and dealers in securities or currencies.
Further, we do not address:

     - the United States federal income tax consequences to stockholders in, or
       partners or beneficiaries of, an entity that is a holder of the old notes
       or exchange notes;

     - the United States federal estate and gift or alternative minimum tax
       consequences of the purchase, ownership or sale of the old notes or
       exchange notes;

     - the United States federal income tax consequences to persons who hold the
       old notes or exchange notes in a "straddle" or as part of a "hedging,"
       "conversion" or "constructive sale" transaction or whose "functional
       currency" is not the United States dollar; or

     - any state, local or foreign tax consequences of the purchase, ownership
       and sale of the old notes or the exchange notes.

  ACCORDINGLY, YOU SHOULD CONSULT YOUR OWN TAX ADVISOR REGARDING THE PARTICULAR
  TAX CONSEQUENCES OF EXCHANGING FOR, OWNING AND SELLING THE EXCHANGE NOTES IN
  LIGHT OF YOUR CIRCUMSTANCES.

     A "United States Holder" is a beneficial owner of the exchange notes who,
for United States federal income tax purposes, is:

     - an individual who is a citizen or resident of the United States;

     - a corporation or another entity taxable as a corporation created or
       organized in or under the laws of the United States or any political
       subdivision thereof or therein;

     - an estate if its income is subject to United States federal income
       taxation regardless of its source;

     - a trust if (1) a United States court can exercise primary supervision
       over its administration and (2) one or more United States persons have
       the authority to control all of its substantial decisions; or

     - specified electing trusts that were in existence on August 20, 1996 and
       treated as domestic trusts on that date.

     If a partnership holds the exchange notes, the tax treatment of a partner
will generally depend upon the status of the partner and upon the activities of
the partnership.

     A "Foreign Holder" is a beneficial owner of the exchange notes other than a
United States Holder.

     This summary is based on the currently existing provisions of the Code,
Treasury regulations issued under the Code, and administrative judicial
interpretations thereof, all as they currently exist as of the date of this
prospectus and all of which are subject to change, possibly with retroactive
effect, or different interpretations. Legislative, judicial, or administrative
changes or interpretations may be forthcoming that could alter or modify the
statements and conclusions made below and that could affect the tax consequences
discussed below. We have not asked, and do not intend to ask, for a ruling from
the Internal Revenue Service on any of the tax consequences discussed below.
Accordingly, we can give you no assurance that the Internal Revenue Service will
not take a contrary view.

                                       103


UNITED STATES FEDERAL INCOME TAXATION OF UNITED STATES HOLDERS

     Payment of Interest on the Exchange Notes.  Interest paid or payable on an
exchange note will be taxable to a United States Holder as ordinary income,
generally at the time it is received or accrued, in accordance with such
holder's regular method of accounting for United States federal income tax
purposes.

     Exchange Offer.  The exchange of old notes for exchange notes in the
Registered Exchange Offer will not constitute a taxable event for United States
Holders. Consequently, a United States Holder will not recognize gain or loss on
the exchange, the holding period of the exchange note will include the holding
period of the old note, and the basis of the exchange note will be the same as
the basis of the old note immediately before the exchange.

     If a United States Holder receives additional interest, we believe it
should be treated in the same manner as regular interest on the exchange notes.
However, the United States Holder might instead be required to report it as
income when it accrues or becomes fixed, even if the United States Holder is a
cash method taxpayer.

     Sale, Exchange or Retirement of the Exchange Notes.  Upon the sale,
exchange, redemption, retirement at maturity or other disposition of an exchange
note, a United States Holder generally will recognize taxable gain or loss equal
to the difference between the sum of cash plus the fair market value of all
non-cash property received on such disposition (except to the extent such cash
or property is attributable to accrued, but unpaid, interest, which will be
taxable as ordinary income) and such United States Holder's adjusted tax basis
in the exchange note. A United States Holder's adjusted tax basis in an exchange
note generally will equal the cost of the old note to such United States Holder.
Gain or loss recognized on the disposition of an exchange note will be long-term
capital gain or loss if, at the time of such disposition, the United States
Holder's holding period for the note is more than one year. Long-term capital
gain realized by individual taxpayers is generally taxable at a maximum rate of
20 percent. The deductibility of capital losses is subject to limitations.

     Backup Withholding and Information Reporting.  Backup withholding and
information reporting requirements may apply to payments made with respect to
the exchange notes. We, or our agent or a broker, as the case may be, will be
required to withhold from any payment that is subject to backup withholding
United States federal income tax a portion of such payment not to exceed 30%, if
a United States Holder fails to furnish its taxpayer identification number
(social security or employer identification number) or otherwise fails to comply
with the applicable requirements of the backup withholding rules. Corporations
and certain other entities are generally exempt from the backup withholding and
information reporting requirements. Generally, income on the notes will be
reported to non-exempt United States Holders on an applicable Internal Revenue
Service Form 1099.

     Any amounts withheld under the backup withholding rules from a payment to a
United States Holder will be allowed as a credit against such United States
Holder's United States federal income tax liability and may entitle the United
States Holder to a refund, provided that the required information is furnished
to the Internal Revenue Service by the United States Holder in a timely manner.

UNITED STATES FEDERAL INCOME TAXATION OF FOREIGN HOLDERS

     Payment of Interest on the Exchange Notes.  Payments of interest to a
Foreign Holder that are not effectively connected to the conduct of a United
States trade or business will generally not be subject to United States federal
income tax, or the withholding thereof, provided the Foreign Holder:

     - does not own (directly or indirectly, actually or constructively) 10% or
       more of the total combined voting power of all classes of our capital
       stock entitled to vote;

     - is not a controlled foreign corporation that is related to us through
       stock ownership; and

     - is not a bank receiving interest described in section 881(c)(3)(A) of the
       Code.

     A Foreign Holder that receives interest payments that are not effectively
connected with a United States trade or business but that does not satisfy each
of the three above mentioned conditions will be subject to

                                       104


withholding tax at a rate of 30%, unless a United States income tax treaty
applies to reduce or eliminate withholding.

     To qualify for exemption from withholding, the last United States payor in
the chain of payment prior to payment to a Foreign Holder (the "withholding
agent") must have received in the year in which a payment of interest or
principal occurs, or in either of the two preceding calendar years, a statement
that:

     - is signed by the Foreign Holder under penalties of perjury;

     - certifies that the holder of the securities is a Foreign Holder; and

     - provides the name and address of the Foreign Holder.

     The statement may be made on an Internal Revenue Service Form W-8BEN or a
substantially similar form, and the Foreign Holder must inform the withholding
agent of any change in the information on the statement within 30 days of any
change. If the notes are held through a securities clearing organization or
certain other financial institutions that are not qualified intermediaries, the
organization or institution may provide a signed statement to the withholding
agent along with a copy of Internal Revenue Service Form W-8BEN or a substitute
form provided by the Foreign Holder. If the financial institution is a qualified
intermediary, it generally will not be required to furnish a copy of the
Internal Revenue Service Form W-8BEN. A qualified intermediary is a financial
institution that has entered into a withholding agreement with the Internal
Revenue Service.

     Exchange Offer.  The exchange of old notes for exchange notes in the
Registered Exchange Offer will not constitute a taxable event for Foreign
Holders. Consequently, for United States federal income tax purposes, a Foreign
Holder will not recognize gain or loss on the exchange, the holding period of
the exchange note will include the holding period of the old note, and the basis
of the exchange note will be the same as the basis of the old note immediately
before the exchange. If a Foreign Holder receives additional interest on the
exchange notes, we believe it should be treated in the same manner as regular
interest on the notes.

     Sale, Exchange or Retirement of the Exchange Notes.  A Foreign Holder will
generally not be subject to United States federal income tax, or the withholding
thereof, on any gain realized upon the sale, exchange, redemption, retirement at
maturity or other disposition of the exchange notes. If, however, the gain is
effectively connected with the conduct of a trade or business within the United
States by the Foreign Holder or if the Foreign Holder is present in the United
States for 183 days or more during the taxable year of sale, redemption,
retirement or other disposition and certain other conditions are met, the
Foreign Holder may be subject to income tax on all income and gains recognized.

     United States Trade or Business.  If a Foreign Holder holds the exchange
notes in connection with a trade or business that the Foreign Holder is
conducting in the United States:

     - Any interest on the exchange notes, and any gain from disposing of the
       exchange notes, generally will be subject to income tax as if the Foreign
       Holder were a United States Holder.

     - If the Foreign Holder is a corporation, the Foreign Holder may be subject
       to the "branch profits tax" on the earnings that are connected with
       Foreign Holder's United States trade or business, including earnings from
       the notes. This tax is 30%, but may be reduced or eliminated by an
       applicable United States income tax treaty.

     Backup Withholding and Information Reporting.  Backup withholding and
information reporting requirements do not apply to payments of interest made to
Foreign Holders if the certification needed to avoid withholding tax on
interest, as described above, is received, provided that the payor does not have
actual knowledge that the Holder is a United States Holder. If any payments of
principal and interest are made to the beneficial owner of an exchange note by
or through the foreign office of a foreign custodian, foreign nominee or other
foreign agent of such beneficial owner, or if the foreign office of a foreign
"broker" (as defined in applicable United States Treasury regulations) pays the
proceeds of the sale of an exchange note effected outside the United States to
the seller thereof, backup withholding and information reporting will not apply.
Information reporting requirements (but not backup withholding) will apply,
however, to a payment by

                                       105


or through a foreign office of a broker of principal and interest or the
proceeds of a sale of an exchange note effected outside the United States if
that broker has specified types of relationships with the United States, unless
the broker has documentary evidence in its records that the holder is a Foreign
Holder and certain other conditions are met or the Foreign Holder otherwise
establishes an exemption. Payment by a United States office of a broker is
subject to both backup withholding at a rate not to exceed 30% and information
reporting unless the holder certifies, under penalties of perjury, in the manner
required as to its Foreign Holder status or otherwise establishes an exemption.

                                       106


                              PLAN OF DISTRIBUTION

     Based on interpretations of the SEC set forth in no-action letters issued
to third parties, we believe that the exchange notes issued under the exchange
offer in exchange for old notes may be offered for resale, resold and otherwise
transferred by you without compliance with the registration and prospectus
delivery provisions of the Securities Act, if:

     - you are not an "affiliate" of ours within the meaning of Rule 405 under
       the Securities Act;

     - you are acquiring the exchange notes in the ordinary course of your
       business; and

     - you do not intend to participate in the distribution of the exchange
       notes.

     If you tender old notes in the exchange offer with the intention of
participating in any manner in a distribution of the exchange notes:

     - you cannot rely on those interpretations of the SEC; and

     - you must comply with the registration and prospectus delivery
       requirements of the Securities Act in connection with a secondary resale
       transaction, and the secondary resale transaction must be covered by an
       effective registration statement containing the selling security holder
       information required by Item 507 or 508, as applicable, of Regulation S-K
       under the Securities Act.

     Each broker-dealer that receives the exchange notes for its own account
pursuant to the exchange offer must acknowledge that it will deliver a
prospectus in connection with any resale of the exchange notes. This prospectus,
as it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of exchange notes received in exchange
for old notes where the old notes were acquired as a result of market-making
activities or other trading activities. We have agreed that, for a period of 180
days after the exchange offer is completed, we will make this prospectus, as
amended or supplemented, available to any broker-dealer for use in connection
with any resale of exchange notes. In addition, until 90 days after the date of
this prospectus, all dealers effecting transactions in the exchange notes may be
required to deliver a prospectus.

     We will not receive any proceeds from any sales of the exchange notes by
broker-dealers. The exchange notes received by broker-dealers for their own
account pursuant to the exchange offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the exchange notes or a combination of methods
of resale, at market prices prevailing at the time of resale, at prices related
to those prevailing market prices or at negotiated prices. Any resale may be
made directly to the purchaser or to or through brokers or dealers who may
receive compensation in the form of commissions or concessions from the
broker-dealer and/or the purchasers of the exchange notes. Any broker-dealer
that resells the exchange notes that were received by it for its own account
pursuant to the exchange offer and any broker or dealer that participates in a
distribution of the exchange notes may be deemed to be an "underwriter" within
the meaning of the Securities Act and any profit on any resale of exchange notes
and any commissions or concessions received by any of those persons may be
deemed to be underwriting compensation under the Securities Act. The letter of
transmittal states that, by acknowledging that it will deliver and by delivering
a prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

     For a period of 180 days after the exchange offer is completed we will
promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such documents
in the letter of transmittal. We have agreed to pay the expenses incident to the
exchange offer, other than commissions or concessions of any brokers or dealers
and the fees of any advisors or experts retained by the holders of old notes,
and will indemnify the holders of the old notes (including any broker-dealers)
against related liabilities, including liabilities under the Securities Act.

                         INDEPENDENT PUBLIC ACCOUNTANTS

     Our consolidated financial statements as of December 31, 2001 and for the
year then ended have been included or incorporated by reference in this
prospectus in reliance upon the report of Arthur Andersen LLP, independent
certified public accountants and upon the authority of said firm as experts in
accounting and auditing.

     After reasonable efforts, however, we have been unable to obtain Arthur
Andersen's written consent to the inclusion or incorporation by reference of our
consolidated financial statements in this prospectus.

     Section 11(a) of the Securities Act provides that if any part of a
registration statement at the time it becomes effective contains an untrue
statement of a material fact or an omission to state a material fact required to
be stated therein or necessary to make the statements therein not misleading,
any person acquiring a security pursuant to such registration statement (unless
it is proved that at the time of acquisition that such person knew of such
untruth or omission) may sue, among others, every accountant who has consented
to be named as having prepared or certified any part of the registration
statement with respect to the statement in such registration statement, report
or valuation which purports to have been prepared or certified by the
accountant. Since Arthur Andersen LLP has not consented to the incorporation by
reference of our consolidated financial statements into the registration
statement of which this prospectus is a part, you will not be able to recover
against Arthur Andersen LLP under Section 11 of the Securities Act for any
untrue statements of a material fact contained in our consolidated financial
statements or any omissions to state a material fact required to be stated
therein.

     Estimated quantities of our oil and natural gas reserves and the present
value of such reserves as of September 30, 2002 are based upon reserve reports
prepared by Westport's engineering staff. At December 31, 2001, Ryder Scott
Company, L.P. audited 87% of the total net present value of estimates of total
proved reserves and the remaining 13% of net present value of the reserves was
unaudited. Estimates of total proved reserves at December 31, 2000 were prepared
by Ryder Scott and Netherland, Sewell and Associates, Inc. and our engineering
staff. The Ryder Scott and Netherland Sewell reports covered approximately 85%
of the total net present value of the reserves, and the internally generated
report covered the remaining 15% of the net present value. Ryder Scott Company,
L.P. and Netherland, Sewell and Associates, Inc. are independent consulting
petroleum engineers and certain information with respect to the oil and natural
gas reserves is derived from their reports and have been incorporated by
reference in this prospectus upon the authority of said firms as experts with
respect to the matters covered by such reports and in giving such reports.

     Certain information with respect to the oil and natural gas reserves
associated with the Acquired Properties is derived from the reports of the Ryder
Scott Company, L.P., independent consulting petroleum engineers, and has been
included or incorporated by reference in this prospectus upon the authority of

wells is drilled within the proven boundaries of a field between two or more
other wells.

     Injector Well or Injector.  A well which is used to place liquids or gases

from new wells on undrilled acreage or from existing wells where a relatively
major expenditure is required for recompletion.

     Royalty.  An interest in an oil and natural gas lease that gives the owner
of the interest the right to receive a portion of the production from the leased
acreage (or of the proceeds of the sale thereof), but generally does not require
the owner to pay any portion of the costs of drilling or operating the wells on
the leased acreage. Royalties may be either landowner's royalties, which are
reserved by the owner of the leased acreage at the time the lease is granted, or
overriding royalties, which are usually reserved by an owner of the leasehold in
connection with a transfer to a subsequent owner.

the producing formation in order to maintain reservoir pressure and force oil
toward and into the producing wells.

     Working Interest.  An interest in an oil and natural gas lease that gives
the owner of the interest the right to drill for and produce oil and natural gas
on the leased acreage and requires the owner to pay a share of the costs of
drilling and production operations.

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

     The Nevada Revised Statutes, or the NRS, provide that a corporation may
indemnify any person who was or is a party or is threatened to be made a party,
by reason of the fact that such person was an officer or director of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, to:

     - any action or suit by or in the right of the corporation against
       expenses, including amounts paid in settlement and attorneys' fees,
       actually and reasonably incurred, in connection with the defense or
       settlement, if such person acted in good faith and in a manner that he or
       she reasonably believed to be in, or not opposed to, the best interests
       of the corporation, except that indemnification may not be made for any
       claim, issue or matter as to which such a person has been adjudged by a
       court of competent jurisdiction to be liable to the corporation or for
       amounts paid in settlement to the corporation unless and only to the
       extent that the court in which the action or suit was brought or other
       court of competent jurisdiction determines upon application that in view
       of all of the circumstances of the case, the person is fairly and
       reasonably entitled to indemnity for such expenses as the court deems
       proper; and

     - any other action or suit or proceeding against expenses, including
       attorneys' fees, judgments, fines and amounts paid in settlement,
       actually and reasonably incurred, if he or she acted in good faith and in
       a manner which he or she reasonably believed to be in, or not opposed to,
       the best interests of the corporation, and, with respect to any criminal
       action or proceeding, had no reasonable cause to believe his or her
       conduct was unlawful. To the extent that a director, officer, employee or
       agent has been "successful on the merits or otherwise" the corporation
       must indemnify such person. The articles of incorporation or bylaws may
       provide that the expenses of officers and directors incurred in defending
       any such action must be paid as incurred and in advance of the final
       disposition of such action. The NRS also permits the registrant to
       purchase and maintain insurance on behalf of the registrant's directors
       and officers against any liability arising out of their status as such,
       whether or not the registrant would have the power to indemnify him or
       her against such liability. These provisions may be sufficiently broad to
       indemnify such persons for liabilities arising under the Securities Act.

     Our articles of incorporation eliminate a director's personal liability to
Westport or its stockholders for damages for breach of fiduciary duty as a
director, unless a director is engaged in (a) any breach of the director's duty
of loyalty to Westport or its stockholders, (b) acts or omissions which involve
intentional misconduct, fraud or a knowing violation of law; (c) the payment of
illegal distributions, or (d) any transaction from which the director derived an
improper personal benefit.

     Subject to the foregoing, our articles of incorporation provide that we
will indemnify, to the maximum extent permitted by the NRS, any officer or
director of Westport, or any person serving at our request as a director or
officer of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorney's fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with any action, suit or proceeding brought by third parties. In a
derivative action, i.e., one by or in the right of the corporation,
indemnification will be made, to the maximum extent permitted by the NRS, only
for expenses (including attorney's fees) actually and reasonably incurred by
such persons in connection with the defense or settlement of any action or suit
to procure a judgment in our favor. To the extent that a present or former
director or officer of Westport has been successful on the merits or otherwise
in defense of any such action, suit or proceeding, or in defense of any claim,
issue or matter therein, such person will be indemnified against expenses
(including attorney's fees) actually and reasonably incurred by such person in
connection therewith.

     These expenses will be paid by us in advance of the final disposition of
such action, suit or proceeding upon receipt of an undertaking by a director or
officer to repay the advanced amount if it is ultimately determined that such
person is not entitled to be indemnified by us pursuant to the NRS or our
articles of
                                       II-1


incorporation. The indemnification and advancement of expenses will not be
deemed exclusive of any other rights to which any director or officer of
Westport seeking indemnification or advancement of expenses may be otherwise
entitled.

     Our articles of incorporation also permit us to purchase and maintain
insurance on behalf of any person who is or was a director or officer of
Westport, or is or was serving at our request as a director or officer of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability incurred by such person in any such capacity or arising
out of such person's status as officer or director regardless of our power to
indemnify such person under the provision of the NRS or articles of
incorporation.

     We have entered into indemnification agreements with our directors and
officers. The agreements provide for indemnification of each such person to the
fullest extent authorized or permitted by Nevada law as it exists now or may
hereafter be amended or changed. Subsequent amendments or changes in Nevada law
affecting indemnification rights will govern the agreements only to the extent
the amendments or changes in law authorize or permit broader indemnification
protections that those permitted prior to such amendments or changes.

     Pursuant to the agreements, we also agreed to pay on behalf of each
indemnitee expenses incurred by such indemnitee by reason of the fact that the
person is or was a director or officer of Westport, provided that such person is
otherwise entitled to indemnification. If it is ultimately determined that such
director or officer is not entitled to indemnification, any advances made by us
to such person will be interest-free. We also agreed to maintain directors' and
officers' liability insurance in reasonable amounts from established and
reputable insurers for as long as such directors or officers continue to serve
in such capacity or remain subject to liability as a result of their service as
our directors or officers.

     In addition, we will pay expenses and fees of separate counsel for each
individual defendant in any indemnification proceeding where there are conflicts
of interest among defendants. In the event of a change in control of Westport,
each indemnitee also has a right to select independent counsel, subject to the
company's approval, which may not be unreasonably withheld. The independent
counsel will determine the rights of such indemnitee to indemnification and
payment of expenses provided by the indemnification agreement, the standard of
conduct applicable to the indemnitee and the reasonableness of amounts claimed
by such indemnitee. Westport will pay reasonable expenses and fees of such
counsel.

     Pursuant to the merger agreement dated as of June 8, 2001, between Westport
Resources Corporation, a Delaware corporation, or Old Westport, and Belco Oil &
Gas Corp., or Belco, we are obligated, for six years after the effective time of
the merger with Belco, to indemnify, defend and hold harmless each person who
has been at any time prior to the effective time of the merger, an officer or
director of Westport, Belco or any of their respective subsidiaries who acted as
a fiduciary under any of Old Westport's Benefit Plans or Belco's Benefit Plans
(each as defined in the merger agreement) against all losses, claims, damages,
liabilities, fees and expenses arising in whole or in part out of actions or
omissions in their capacity as such occurring at or prior to the effective time
of the merger to the full extent permitted under Nevada law or our articles of
incorporation and bylaws and Old Westport's and Belco's written indemnification
agreements in effect as of June 8, 2001. Any determination of whether a person's
conduct complies with the required standard will be made by the independent
counsel acceptable to both Westport and the indemnified party.

     Pursuant to the merger agreement, we also maintain Westport's and Belco's
directors' and officers' liability insurance policies in effect as of the
effective time of the merger for a period of not less than six years after the
effective time of the merger, but only to the extent related to actions or
omissions prior to the effective time of the merger, subject to certain
provisions.

     Pursuant to the second amended and restated shareholders' agreement, dated
July 20, 2001, between Westport, ERI Investments, Inc., or ERI, Westport Energy
LLC, or WELLC, and a group of former stockholders of Belco, also known as the
Belfer Group, we have agreed to indemnify ERI, WELLC, the Belfer Group and each
of their directors, officers and controlling persons to the extent permitted by
law against any losses, claims, damages or liabilities to which such person may
become subject under the Securities Act that arise out of any untrue or alleged
untrue statement of a material fact or any omission or alleged omission of a

                                       II-2


material fact required to be contained in a registration statement, prospectus,
application or other documentation to be filed with the SEC.

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

ITEM 22.  UNDERTAKINGS

     (a) The undersigned registrants hereby undertake:

          (1) 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 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and

             (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 (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Exchange Act that are
incorporated by reference in the registration statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act, 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.

          (3) To 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.

     (b) The registrants hereby undertake that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrants'
annual report pursuant to Section 13(a) or Section 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in this registration
statement shall be

                                       II-5


deemed to be a new registration statement relating to the securities offered
herein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrants pursuant to the foregoing provisions, or otherwise, the
registrants have been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrants of expenses
incurred or paid by a director, officer or controlling person of the registrants
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 registrants 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 and will be governed by
the final adjudication of such issue.

     (d) The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.

     (e) The undersigned registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                                       II-6


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the registrants
have duly caused this registration statement to be signed on their behalf by the
undersigned, thereunto duly authorized, in the City of Denver, State of
Colorado, on January 24, 2003.
