TERMS OF THE EXCHANGE OFFER:

     - We are offering to exchange up to $100.0 million aggregate principal
       amount of registered 7 1/8% Senior Notes due 2012, which we refer to as
       the new notes, for any and all of our $100.0 million aggregate principal
       amount of unregistered 7 1/8% Senior Notes due 2012, which we refer to as
       the old notes, that were issued on April 8, 2005. The new notes are being
       offered as additional debt securities under the indenture pursuant to
       which we previously issued $175.0 million aggregate principal amount of
       7 1/8% Senior Notes due 2012, which we refer to as the previously issued
       notes, and will be treated together with the previously issued notes as a
       single class of debt securities under the indenture governing the notes.

     - We will exchange all outstanding old notes that are validly tendered and
       not validly withdrawn prior to the expiration of the exchange offer for
       an equal principal amount of new notes.

     - The terms of the new notes are substantially identical to those of the
       outstanding old notes, except that the transfer restrictions and
       registration rights relating to the old notes do not apply to the new
       notes.

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

     - The exchange of new notes for old notes will not be a taxable transaction
       for U.S. federal income tax purposes.

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

     - The old notes are, and the new notes will be, guaranteed on a senior
       unsecured basis by all of our current and certain future domestic
       restricted subsidiaries, other than certain immaterial subsidiaries.

     - There is no established trading market for the new notes or the old
       notes.

     - We do not intend to apply for listing of the new notes on any national
       securities exchange or for quotation through any quotation system,
       including The Nasdaq National Market.

     THIS INVESTMENT INVOLVES RISKS. PLEASE READ "RISK FACTORS" BEGINNING ON
PAGE 12 FOR A DISCUSSION OF THE RISKS THAT YOU SHOULD CONSIDER PRIOR TO
TENDERING YOUR OUTSTANDING OLD NOTES IN THE EXCHANGE OFFER.

     NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR DETERMINED IF THIS
PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

     Each broker-dealer that receives new 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 new 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 new 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. Please read "Plan of
Distribution."

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

     The information discussed in this prospectus, our filings with the SEC and
our public releases include "forward-looking statements" within the meaning of
Section 27A of the Securities Act of 1933, as amended, referred to as the
Securities Act, and Section 21E of the Exchange Act. All statements, other than
statements of historical facts, included herein concerning, among other things,
planned capital expenditures, increases in oil and gas production, the number of
anticipated wells to be drilled after the date hereof, future cash flows and
borrowings, pursuit of potential acquisition opportunities, our financial
position, business strategy and other plans and objectives for future
operations, are forward-looking statements. These forward-looking statements are
identified by their use of terms and phrases such as "may," "will," "expect,"
"estimate," "project," "plan," "believe," "achievable," "anticipate" and similar
terms and phrases. Although we believe that the expectations reflected in these
forward-looking statements are reasonable, they do involve certain assumptions,
risks and uncertainties. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including, among others:

     - the timing and success of our drilling activities;

     - the volatility of prices and supply of, and demand for, oil and natural
       gas;

     - the numerous uncertainties inherent in estimating quantities of proved
       oil and natural gas reserves and actual future production rates and
       associated costs;

     - our ability to successfully identify, execute or effectively integrate
       future acquisitions;

     - the usual hazards associated with the oil and gas industry (including
       fires, natural disasters, well blowouts, adverse weather conditions, pipe
       failure, spills, explosions and other unforeseen hazards);

     - our ability to effectively market our oil and natural gas;

     - the results of our hedging transactions;

     - the availability of rigs, equipment, supplies and personnel;

     - our ability to acquire or discover additional reserves;

     - our ability to satisfy future capital requirements;

     - changes in regulatory requirements;

     - the credit risks associated with our customers;

     - economic and competitive conditions;

     - our ability to retain key members of our senior management and key
       employees;

     - uninsured judgments or a rise in our insurance premiums;

     - our outstanding indebtedness;

     - continued hostilities in the Middle East and other sustained military
       campaigns and acts of terrorism or sabotage; and

     - if underlying assumptions prove incorrect.

     Finally, our future results will depend upon various other risks and

                                ABOUT KCS ENERGY

     We are an independent oil and gas company engaged in the acquisition,
exploration, development and production of natural gas and crude oil. Our
properties are primarily located in the Mid-Continent and onshore Gulf Coast
regions of the United States. We also have interests in producing properties in
Michigan, California, Wyoming and offshore Gulf of Mexico. As of December 31,
2004, our oil and natural gas properties were estimated to have net proved
reserves of 328 Bcfe with a PV-10 value of approximately $814 million.
Approximately 88% of our net proved reserve base was natural gas and
approximately 76% was classified as proved developed. We operate approximately
84% of our proved oil and natural gas reserve base. The following table sets
forth the estimated quantities of proved reserves attributable to our principal
operating regions as of December 31, 2004.

     In 2004, we produced an average of 109.2 MMcfe per day compared to 95.2
MMcfe per day in 2003. We plan to continue growing our reserves and production
through a balanced investment program in low-risk exploitation activities in the
Mid-Continent and Gulf Coast regions and moderate-risk, higher potential
exploration drilling programs, primarily in the onshore Gulf Coast region. We
also intend to continue to evaluate potential oil and gas property acquisitions
to expand our acreage position and drilling inventory.

                                2004 HIGHLIGHTS

     In the year ended December 31, 2004, we drilled a record 130 wells, of
which 126 were completed, resulting in a 97% success rate and significantly
increased production and reserves. In 2004, gross production increased 15%, to
40 Bcfe, while net production, after production payment delivery obligations,
that do not contribute to cash flow from operating activities, increased 25%, to
34.8 Bcfe, compared to 2003. Natural gas and oil reserves increased 22% to 328
Bcfe as of December 31, 2004 compared to 268 Bcfe as of December 31, 2003. In
total, we added 94.5 Bcfe of proved reserves during 2004, of which 97% was
through the drill bit. Total oil and gas capital expenditures were $166.7
million.

     In 2004, we continued to execute our strategies of focusing on low-risk
development and exploitation drilling in our core operating areas and committing
approximately 15% of our capital expenditure budget to moderate-risk,
higher-potential exploration prospects primarily in the onshore Gulf Coast
region. In 2005, we plan to commit approximately 15% to 20% of our capital
expenditure budget to such exploration projects. We continue to focus primarily
on natural gas prospects. We have continued our disciplined hedging program
designed to protect against price declines while participating to a large extent
in future price increases. In this

                                        1


way, we endeavor to ensure that we generate a sufficient level of cash flow to
carry out a capital expenditure program sufficient to at least replace our
expected production and still benefit if prices rise.

     We further strengthened our financial condition in 2004 and provided
additional financial flexibility by completing a $175.0 million senior notes
offering. The senior notes bear interest at an annual rate of 7 1/8% and mature
in 2012. The proceeds of this issuance were used to redeem our $125.0 million
8 7/8% senior subordinated notes due 2006, including an early redemption
premium, to repay the $22.0 million outstanding under our bank credit facility
and for general corporate purposes. We plan to maintain a conservative capital
structure.

     We believe that the steps taken during 2004, along with our multi-year
drilling prospect inventory, position us to increase production and reserves in
the future.

                              RECENT DEVELOPMENTS

     OIL AND GAS PROPERTY ACQUISITION.  On April 13, 2005, we consummated the
acquisition of oil and gas properties and related assets located primarily in
our North Louisiana -- East Texas core operating area. The properties and
related assets acquired include currently producing wells, equipment,
undeveloped leases and future drilling locations. We are entitled to all of the
rights of ownership (including, without limitation, the right to all production,
proceeds of production, and other proceeds) and are responsible for all
operating expenses and liabilities attributable to the assets for the period of
time after January 1, 2005. The properties, which are currently producing
between 6 and 7 MMcfe per day, include internally estimated net proved reserves
of approximately 47 Bcfe, of which approximately two-thirds are undeveloped. The
adjusted purchase price for the properties was approximately $86.9 million and
was funded with the net proceeds of the private offering of the old notes.

     ISSUANCE OF OLD NOTES.  On April 8, 2005, we issued $100.0 million
aggregate principal amount of 7 1/8% Senior Notes due 2012 in accordance with a
private placement conducted pursuant to Rule 144A under the Securities Act. The
old notes were issued at 100.625% of the face amount for gross proceeds of
approximately $98.2 million, after deducting estimated expenses and the initial
purchasers' discounts. We used the net proceeds of the private placement to
finance the purchase price of our acquisition of oil and gas properties and
related assets located primarily in our North Louisiana-East Texas core
operating area and to repay indebtedness under our bank credit facility. The old
notes were issued as additional debt securities under the indenture pursuant to
which we previously issued $175.0 million aggregate principal amount of 7 1/8%
Senior Notes due 2012. The old notes constitute a single class of securities
with the previously issued notes under the indenture.

     INCREASED BANK CREDIT FACILITY.  On March 31, 2005, we amended our amended
and restated bank credit facility with a group of commercial bank lenders to,
among other things, increase the maximum commitment amount from $100.0 million
to $250.0 million, extend the maturity date to March 31, 2009 and permits an
additional $25.0 million of indebtedness for money borrowed (in addition to the
$175.0 million of previously issued notes and the $100.0 million of old notes).
In connection with the amended facility, the lenders approved an increase in the
borrowing base, which is redetermined semi-annually, from $100.0 million to
$185.0 million. However, pursuant to the amendment, the borrowing base will
automatically be reduced by an amount equal to a specified percentage of the net
proceeds from the issuance of additional indebtedness that is not applied to
refinance existing indebtedness. As a result of the application of this
provision, upon the issuance of the old notes, the borrowing base was
automatically reduced by $20.0 million to $165.0 million. As of June 30, 2005,
$15.0 million was outstanding under the bank credit facility.

                 COMPETITIVE STRENGTHS AND BUSINESS STRATEGIES

     We intend to continue to increase production and reserves to optimize
stockholder value by executing the following strategies:

     - FOCUS ON NATURAL GAS -- As of December 31, 2004, our proved reserves were
       88% natural gas. We believe that the future need for natural gas in the
       United States will continue to grow. In addition, North American supplies
       of natural gas have been declining in recent years. Lease operating
       expenses associated with natural gas properties are also typically less
       than oil properties, which allows us to maintain our low per-unit cost
       structure.

     - GROW THROUGH THE DRILL BIT -- We believe our personnel possess
       exceptional knowledge in identifying, drilling and stimulating tight rock
       formations. Over the last three years ended December 31, 2004, we have
       added 217 Bcfe to our reserves, of which 95% were through the drill bit.
       Oil and gas capital expenditures during the last three years ended
       December 31, 2004 were $302.8 million. With our inventory of drilling
       prospects, we believe that we are well-positioned to continue growing our
       reserves and production.

     - EXPLOIT OUR LARGE INVENTORY OF DRILLING PROJECTS -- We have a significant
       inventory of future drilling locations in targeted areas. Generally,
       these locations range in depth from 5,000 feet to 13,000 feet and are
       low-risk opportunities. Most of the locations are step-out or extension
       wells from existing production.

     - CONCENTRATE IN CORE AREAS -- We concentrate our drilling programs
       predominately in the Mid-Continent and Gulf Coast regions. Operating in
       concentrated areas helps us to better control our overhead by enabling us
       to manage a greater amount of acreage with fewer employees and minimize
       incremental costs of increased drilling and production. Our strategy of
       targeting our operations in relatively concentrated areas permits us to
       more efficiently capitalize on our base of geological, engineering,
       exploration, development, completion and production experience in these
       regions. The areas we produce generally have high price realizations
       relative to benchmark prices for natural gas production and favorable
       operating costs.

     - CONTROL DRILLING AND PRODUCTION OPERATIONS -- We operated approximately
       84% of our proved oil and natural gas reserve base as of December 31,
       2004. We prefer to generate and retain operating control over our own
       prospects rather than owning non-operated interests. This allows us to
       more effectively control operating costs, the timing and plans for future
       development, the level of drilling and the marketing of production on the
       properties. In addition, as an operator, we receive reimbursements for
       overhead from other working interest owners, which reduces our general
       and administrative expenses. During the year ended December 31, 2004, we
       controlled the drilling operations on 93 of the 130 wells in which we
       participated.

     - SEARCH FOR COMPLEMENTARY ACQUISITIONS -- We proactively search for
       acquisitions in our core areas to expand our acreage position and
       drilling inventory. Two recent examples of this were the O'Connor Ranch
       lease acquisition in the third quarter of 2004 that compliments our south
       Texas drilling program and our acquisition of oil and gas properties and
       related assets located primarily in our North Louisiana -- East Texas
       core operating area that closed in mid-April 2005.

     - EMPLOY EXPERIENCED TECHNICAL PROFESSIONALS -- We employ oil and gas
       professionals, including geophysicists, petrophysicists, geologists,
       petroleum engineers, production and reservoir engineers and landmen who
       have an average of approximately 25 years of experience in their
       technical fields. We continually apply our extensive in-house expertise
       and advanced technologies to benefit our drilling and completion
       operations.

     - MAINTAIN FINANCIAL FLEXIBILITY -- The timing of most of our capital
       expenditures is discretionary. Consequently, we have a significant degree
       of flexibility to adjust the level of expenditures according to market
       conditions. We currently have budgeted approximately $190 million,
       exclusive of acquisitions,

                                        3


       on capital projects in 2005. We expect that these projects will be funded
       primarily with internally generated cash flow.

     - CONTROL RISK -- We allocate approximately 80% of our capital on an annual
       basis to low-risk development and exploitation projects and the remainder
       to moderate-risk exploration plays. We set limits on the amount of
       capital we will invest in any one exploration project. We hedge a portion
       of our oil and natural gas to protect against downward price swings, and
       we control costs closely to ensure the best possible profit margins. In
       addition, we turnkey our drilling operations where economic in order to
       reduce drilling risk.

     The ratio was computed by dividing earnings by fixed charges. For this
purpose, "earnings" represent the aggregate of pre-tax income from continuing
operations before reorganization items and cumulative effect of accounting
change plus fixed charges excluding capitalized interest. "Fixed charges"
include interest expensed, capitalized interest, amortization of debt issuance
costs and the portion of non-capitalized rental expense deemed to be the
equivalent of interest.

                             CORPORATE INFORMATION

     We are a publicly-owned company whose stock is listed on the New York Stock
Exchange under the symbol "KCS." We were incorporated in Delaware in 1988 in

                                 the discussion under the caption "Material
                                 United States Federal Income Tax

                                 offer.

Use of Proceeds...............   The issuance of the new notes will not provide
                                 us with any new proceeds. We are making this
                                 exchange offer solely to satisfy our
                                 obligations under the registration rights
                                 agreement.

Resales of New Notes..........   Based on interpretations by the staff of the
                                 SEC, as set forth in no-action letters issued
                                 to third parties that are not related to us, we
                                 believe that the new notes you receive in the
                                 exchange offer may be offered for resale,
                                 resold or otherwise transferred by you without
                                 compliance with the registration and prospectus
                                 delivery provisions of the Securities Act so
                                 long as:

                                 - the new notes are being acquired in the
                                   ordinary course of business;

                                 - you are not participating, do not intend to
                                   participate, and have no arrangement or
                                   understanding with any person to participate
                                   in the distribution of the new notes issued
                                   to you in the exchange offer;

                                 - you are not our affiliate; and

                                 - you are not a broker-dealer tendering old
                                   notes acquired directly from us for your
                                   account.

                                 The SEC has not considered this exchange offer
                                 in the context of a no-action letter, and we
                                 cannot assure you that the SEC would make
                                 similar determinations with respect to this
                                 exchange offer. If any of these conditions are
                                 not satisfied, or if our belief is not
                                 accurate, and you transfer any new notes issued
                                 to you in the exchange offer without delivering
                                 a resale prospectus meeting the requirements of
                                 the Securities Act or without an exemption from
                                 registration of your new notes from those
                                 requirements, you may incur liability under the
                                 Securities Act. We will not assume, nor will we
                                 indemnify you against, any such liability. Each

                          DESCRIPTION OF THE NEW NOTES

     The terms of the new notes and those of the outstanding old notes are
substantially identical, except that the transfer restrictions and registration
rights relating to the old notes do not apply to the new notes. As a result, the
new notes will not bear legends restricting their transfer and will not have the
benefit of the registration rights and special interest provisions contained in
the old notes. The new notes represent the same debt as the old notes for which
they are being exchanged. Both the old notes and the new notes are governed by
the same indenture.

     The following is a summary of the terms of the new notes. It may not
contain all the information that is important to you. For a more detailed
description of the new notes, please read "Description of the New Notes."

                                 7 1/8% Senior Notes due 2012. The new notes are
                                 being offered as additional debt securities
                                 under the indenture pursuant to which we
                                 previously issued $175.0 million aggregate
                                 principal amount of 7 1/8% Senior Notes due
                                 2012 and will be treated together with the
                                 previously issued notes as a single class of
                                 debt securities under the indenture governing
                                 the notes. Otherwise unqualified references to
                                 "notes" shall, unless the context requires

                                   registration statement, as the case may be,
                                   is declared effective and such registration

                                 increasing by an additional 0.50% per year with
                                 respect to each subsequent 90-day period until
                                 all defaults have been cured, up to a maximum
                                 additional interest rate of 1.50% per year.

Ranking.......................   The new notes will be our senior unsecured
                                 obligations. The new notes will rank equally
                                 with all our current and future senior
                                 indebtedness. The new notes will rank
                                 effectively junior to our
                                        9


                                 secured debt to the extent of the collateral,
                                 including secured debt under our existing bank
                                 credit facility.

                                 As of March 31, 2005, on an as adjusted basis
                                 after giving effect to the issuance of the old
                                 notes and the consummation of our acquisition
                                 of oil and gas properties and related assets
                                 located primarily in our North
                                 Louisiana -- East Texas core operating area and
                                 our use of the estimated net proceeds from the
                                 issuance of the old notes, we would have had no
                                 indebtedness outstanding other than the $275.0
                                 million aggregate principal amount of our
                                 7 1/8% Senior Notes due 2012. However, we have
                                 a $250.0 million bank credit facility, whose
                                 borrowing base is $165.0 million after the
                                 issuance of the old notes, which, if drawn,
                                 would be secured indebtedness. As of June 30,
                                 2005, $15.0 million was outstanding under the
                                 bank credit facility.

Sinking Fund..................   None.

Optional Redemption...........   On or prior to April 1, 2007, we may redeem up
                                 to 35% of the aggregate principal amount of the
                                 notes (including the new notes) with the net
                                 cash proceeds of certain equity offerings at a
                                 redemption price of 107.125% of the principal
                                 amount thereof plus accrued and unpaid
                                 interest, if any, to the redemption date.
                                 Please read "Description of the New
                                 Notes -- Optional Redemption" for more
                                 information.

                                 On or after April 1, 2008, we may redeem some
                                 or all of the notes at any time at the
                                 redemption prices listed in the section
                                 "Description of the New Notes -- Optional
                                 Redemption."

Mandatory Offer to
  Repurchase..................   If we experience specific kinds of changes of
                                 control or sell certain assets, we must offer
                                 to repurchase the notes at the prices listed in
                                 the section "Description of the New
                                 Notes -- Repurchase at the Option of Holders."

Basic Covenants of
  Indenture...................   We will issue the new notes under the
                                 indenture, as supplemented by the first
                                 supplemental indenture, between us, the
                                 subsidiary guarantors and U.S. Bank National
                                 Association, as trustee. The indenture includes
                                 covenants that will restrict our ability and
                                 the ability of our restricted subsidiaries to,
                                 among other things:

                                 - incur additional indebtedness;

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

                                 - make investments;

                                 - incur liens;

                                 - consolidate;

                                 - merge with or into other companies or
                                   transfer all or substantially all our assets.

                                 - sell assets; and

                                 - engage in transactions with affiliates.
                                        10


                                 These limitations are subject to a number of
                                 important qualifications and exceptions which
                                 are described in "Description of the New
                                 Notes -- Certain Covenants."

Events of Default.............   If there is an event of default on the notes,
                                 the principal amount of notes plus accrued and
                                 unpaid interest, if any, may be declared
                                 immediately due and payable in specified
                                 circumstances. Please read "Description of the
                                 New Notes -- Events of Default and Remedies."

Guarantees....................   The notes will be fully and unconditionally
                                 guaranteed, jointly and severally, on a senior
                                 unsecured basis by all of our current
                                 subsidiaries and our future restricted
                                 subsidiaries, other than certain immaterial
                                 subsidiaries. If we cannot make payments on the
                                 notes when they are due, the guarantor
                                 subsidiaries must make them instead.

                                  RISK FACTORS

     Investing in the new notes involves substantial risk. Please read "Risk
Factors" beginning on page 12 for a discussion of certain factors you should
consider in evaluating an investment in the new notes and in evaluating our
business.

                                        11


                                  RISK FACTORS

     You should consider carefully the following factors, as well as the other
information set forth or incorporated by reference in the prospectus (including
the risks and other disclosure that are presented in our Annual Report on Form
10-K for the year ended December 31, 2004 or other documents filed by us with
the SEC, which are incorporated by reference into this prospectus), before
deciding to participate in the exchange offer. When we use the term "notes" in
this prospectus, unless the context requires otherwise, the term includes the
old notes, the previously issued notes and the new notes.

RISKS RELATED TO THE EXCHANGE OFFER AND THE NEW NOTES

  IF YOU DO NOT PROPERLY TENDER YOUR OLD NOTES, YOU WILL CONTINUE TO HOLD
  UNREGISTERED OUTSTANDING NOTES AND YOUR ABILITY TO TRANSFER OUTSTANDING NOTES
  WILL BE ADVERSELY AFFECTED.

     We will only issue new notes in exchange for old notes that you timely and
properly tender. Therefore, you should allow sufficient time to ensure timely
delivery of the old notes and you should carefully follow the instructions on
how to tender your old notes. Neither we nor the exchange agent is required to
tell you of any defects or irregularities with respect to your tender of old
notes. Please read "The Exchange Offer -- Procedures for Tendering" and
"Description of the New Notes."

     If you do not exchange your old notes for new notes in the exchange offer,
you will continue to be subject to the restrictions on transfer of your old
notes described in the legend on the certificates for your old notes. In
general, you may only offer or sell the old notes if they are registered under
the Securities Act and applicable state securities laws, or offered and sold
under an exemption from these requirements. We do not plan to register any sale
of the old notes under the Securities Act. For further information regarding the
consequences of tendering your old notes in the exchange offer, please read "The
Exchange Offer -- Consequences of Failure to Exchange Outstanding Securities."

  YOU MAY FIND IT DIFFICULT TO SELL YOUR NEW NOTES.

     Although the new notes will trade in The PORTAL(SM) Market and will be
registered under the Securities Act, the new notes will not be listed on any
securities exchange. Because there is no public market for the new notes, you
may not be able to resell them.

     We cannot assure you that an active market will exist for the new notes or
that any trading market that does develop will be liquid. If an active market
does not develop or is not maintained, the market price and liquidity of our new
notes may be adversely affected. If a market for the new notes develops, they
may trade at a discount from their initial offering price. The trading market
for the notes may be adversely affected by:

     - changes in the overall market for non-investment grade securities;

     - changes in our financial performance or prospects;

     - the financial performance or prospects for companies in our industry
       generally;

     - the number of holders of the notes;

     - the interest of securities dealers in making a market for the notes; and

     - prevailing interest rates and general economic conditions.

     Historically, the market for non-investment grade debt has been subject to
substantial volatility in prices. The market for the new notes, if any, may be
subject to similar volatility. Prospective investors in the new notes should be
aware that they may be required to bear the financial risks of such investment
for an indefinite period of time.

  SOME HOLDERS WHO EXCHANGE THEIR OLD NOTES MAY BE DEEMED TO BE UNDERWRITERS.

     If you exchange your old notes in the exchange offer for the purpose of
participating in a distribution of the new notes, you may be deemed to have
received restricted securities and, if so, will be required to comply
                                        12


with the registration and prospectus delivery requirements of the Securities Act
in connection with any resale transaction.

RISKS RELATED TO OUR INDEBTEDNESS AND THE NOTES

  OUR LEVERAGE AND DEBT SERVICE OBLIGATIONS MAY ADVERSELY AFFECT OUR CASH FLOW
  AND OUR FINANCIAL AND OPERATING ACTIVITIES.

     As of March 31, 2005, after giving effect to the issuance of the old notes
and the consummation of our acquisition of oil and gas properties and related
assets located primarily in our North Louisiana -- East Texas core operating
area and the application of the net proceeds to us from the issuance of the old
notes, we would have had total debt of $275.0 million and negative working
capital (excluding derivative liabilities) of $31.6 million. As of May 31, 2005,
we had total debt of $277.5 million and negative working capital (excluding
derivative liabilities) of $41.7 million.

     Our level of indebtedness may have important consequences for us, including
the following:

     - our ability to obtain additional financing for acquisitions, working
       capital or other expenditures could be impaired or financing may not be
       available on acceptable terms;

     - a substantial portion of our cash flow will be used to make interest
       payments on our debt, reducing the funds that would otherwise be
       available for our operations and future business opportunities;

     - a substantial decrease in our revenues as a result of lower oil and
       natural gas prices, decreased production or other factors could make it
       difficult for us to meet debt service requirements and force us to modify
       our operations; and

     - making us more vulnerable to a downturn in our business or the economy in
       general.

  IN ADDITION TO OUR CURRENT INDEBTEDNESS, WE MAY BE ABLE TO INCUR SUBSTANTIALLY
  MORE DEBT. THIS COULD EXACERBATE THE RISKS DESCRIBED ABOVE.

     Together with our subsidiaries, we may be able to incur substantially more
debt in the future. Although our bank credit facility and the indenture
governing the notes contain 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
defined in the relevant agreement. As of March 31, 2005, after giving effect to
the issuance of the old notes and the consummation of our acquisition of oil and
gas properties and related assets located primarily in our North
Louisiana -- East Texas core operating area and the application of the net
proceeds to us from the issuance of the old notes, we would have had no amounts
outstanding under our bank credit facility. As of June 30, 2005, $15.0 million
was outstanding under our bank credit facility. To the extent new debt is added
to our current debt levels, the risks described above could substantially
increase.

  WE ARE DEPENDENT ON OUR SUBSIDIARIES FOR OUR CASH FLOW.

     We are a holding company with no material assets other than the equity
interests of our subsidiaries. Our subsidiaries conduct substantially all of our
operations and directly own substantially all of our assets. Therefore, our
operating cash flow and ability to meet our debt obligations, including the new
notes, will depend on the cash flow provided by our subsidiaries in the form of
loans, dividends or other payments to us as a shareholder, equity holder,
service provider or lender. The ability of our subsidiaries to make such
payments to us will depend on their earnings, tax considerations, legal
restrictions and restrictions under their indebtedness.

                                        13


  THE NOTES ARE NOT SECURED BY OUR ASSETS NOR THOSE OF OUR SUBSIDIARY GUARANTORS
  AND ARE EFFECTIVELY SUBORDINATED TO ALL OF OUR SECURED INDEBTEDNESS TO THE
  EXTENT OF THE VALUE OF ASSETS SECURING SUCH INDEBTEDNESS.

     The notes are our general unsecured obligations and are effectively
subordinated in right of payment to all of our secured indebtedness to the
extent of the value of the assets securing such indebtedness. If we become
insolvent or are liquidated, our assets which serve as collateral under our
secured indebtedness would be made available to satisfy our obligations under
any secured debt before any payments are made on the notes. Our obligations
under our bank credit facility are secured by substantially all of our assets.
As of March 31, 2005, after giving effect to the issuance of the old notes and
the consummation of our acquisition of oil and gas properties and related assets
located primarily in our North Louisiana -- East Texas core operating area and
the application of the net proceeds to us from the issuance of the old notes, we
would have had no indebtedness outstanding other than the $275.0 million
aggregate principal amount of 7 1/8% Senior Notes due 2012. However, we have a
$250.0 million bank credit facility, whose borrowing base is $165.0 million
after the issuance of the old notes, which, if drawn, would be secured
indebtedness. As of June 30, 2005, $15.0 million was outstanding under our bank
credit facility. Although the indenture contains limitations on the amount of
indebtedness that we may incur, under certain circumstances the amount of such
indebtedness could be substantial and, in any case, such indebtedness may be
secured indebtedness. Please read "Description of the New Notes -- Certain
Covenants -- Incurrence of Indebtedness," "-- Liens" and "Description of Other
Indebtedness."

  A SUBSIDIARY GUARANTEE COULD BE VOIDED IF IT CONSTITUTES A FRAUDULENT TRANSFER
  UNDER U.S. BANKRUPTCY OR SIMILAR STATE LAW, WHICH WOULD PREVENT THE HOLDERS OF
  THE NOTES FROM RELYING ON THAT SUBSIDIARY TO SATISFY CLAIMS.

     Under U.S. bankruptcy law and comparable provisions of state fraudulent
transfer laws, a guarantee can be voided, or claims under the guarantee may be
subordinated to all other debts of that guarantor if, among other things, the
guarantor, at the time it incurred the indebtedness evidenced by its guarantee
or, in some states, when payments become due under the guarantee, received less
than reasonably equivalent value or fair consideration for the incurrence of the
guarantee and:

     - was insolvent or rendered insolvent by reason of such incurrence;

     - 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 those debts as they mature.

     A guarantee may also be voided, without regard to the above factors, if a
court found that the guarantor entered into the guarantee with the actual intent
to hinder, delay or defraud its creditors.

     A court would likely find that a guarantor did not receive reasonably
equivalent value or fair consideration for its guarantee if the guarantor did
not substantially benefit directly or indirectly from the issuance of the notes.
If a court were to void a guarantee, you would no longer have a claim against
the guarantor. Sufficient funds to repay the notes may not be available from
other sources, including the remaining guarantors, if any. In addition, the
court might direct you to repay any amounts that you already received from the
subsidiary guarantor.

     The measures of insolvency for purposes of fraudulent transfer laws vary
depending upon the governing law. 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 its assets;

                                        14


     - 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 became absolute and
       mature; or

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

     Each subsidiary guarantee will contain a provision intended to limit the
guarantor's liability to the maximum amount that it could incur without causing
the incurrence of obligations under its subsidiary guarantee to be a fraudulent
transfer. This provision may not be effective to protect the subsidiary
guarantees from being voided under fraudulent transfer law.

  OUR BANK CREDIT FACILITY AND INDENTURE GOVERNING THE NOTES IMPOSE RESTRICTIONS
  ON US THAT MAY AFFECT OUR ABILITY TO SUCCESSFULLY OPERATE OUR BUSINESS AND OUR
  ABILITY TO MAKE PAYMENTS ON THE NEW NOTES.

     Our bank credit facility and the indenture governing the new notes include
covenants that, among other things, restrict our ability to:

     - borrow money;

     - create liens;

     - sell or transfer any of our material property;

     - merge into or consolidate with any third party or sell or dispose of all
       or substantially all of our assets; and

     - make capital expenditures.

     We are also required by our bank credit facility to maintain specified
interest coverage and current ratios. All of these and other future covenants
may restrict our ability to expand or to pursue our business strategies. Adverse
financial or economic developments may cause us to breach these covenants. The
breach of any of these covenants could result in a default under our debt,
causing the debt to become due and payable. We may not be able to repay the debt
due as a result of an acceleration.

     From time to time, we may require consents or waivers from our lenders to
permit any necessary actions that are prohibited by our debt and financing
arrangements. If in the future our lenders refuse to provide any necessary
waivers of the restrictions contained in our debt and financing arrangements,
then we could be in default under our debt and financing arrangements, and we
could be prohibited from undertaking actions that are necessary to maintain and
expand our business.

  UPON A CHANGE OF CONTROL, WE MAY NOT HAVE THE ABILITY TO RAISE THE FUNDS
  NECESSARY TO FINANCE THE CHANGE OF CONTROL OFFER REQUIRED BY THE INDENTURE
  GOVERNING THE NOTES, WHICH WOULD VIOLATE THE TERMS OF THE NOTES.

     Upon the occurrence of a change of control, each holder of the notes will
have the right to require us to purchase all or a portion of such holder's notes
at 101% of the principal amount of the notes, together with accrued and unpaid
interest, if any, to the date of purchase. Our bank credit facility currently
includes a covenant prohibiting certain change of control events with respect to
us. Any future credit agreements or other agreements to which we become a party
may contain similar restrictions and provisions or require the repurchase of the
indebtedness thereunder upon a change of control. The occurrence of a change of
control would result in a default under our bank credit facility and may cause a
default under our future indebtedness and future indebtedness of our
subsidiaries, and give the lenders thereunder the right to require us to repay
obligations outstanding thereunder. Moreover, the exercise by holders of these
notes 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 on us of such repurchase. If a change of control were to
occur, we may not have the financial resources to repay all of the senior and
unsubordinated debt, the notes and the other indebtedness that would become
payable upon the occurrence of such change of control. Our failure to purchase
the notes as required under the indenture would result in a default under the
indenture, which could have material adverse consequences for us and the holders
of the notes.

                                        15


  THE DEFINITION OF THE PHRASE "SUBSTANTIALLY ALL" MAY BE UNCERTAIN.

     The phrase "all or substantially all" is used throughout the indenture in
connection with limiting our activities or providing rights to the holders of
the notes. The phrase "substantially all" is used in the indenture in connection
with:

     - prohibiting our sale of all or substantially all the assets of any
       guarantor;

     - defining "change of control" to include a sale, lease, transfer,
       conveyance or other disposition of "all or substantially all" of our
       assets or assets of our subsidiaries taken as a whole;

     - defining "permitted investment" to permit certain investments in an
       entity that is merged into, consolidated with or otherwise transfers or
       conveys substantially all its assets to us or our restricted
       subsidiaries;

     - permitting the use of proceeds received from an asset sale to acquire
       substantially all the assets of a business engaged in the oil and gas
       business; and

     - prohibiting certain mergers, consolidations and sales of assets involving
       substantially all of our assets.

     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 whether a particular transaction would involve "all or

ability of the holders of the notes to prohibit such transactions or to require
us to repurchase the notes as a result of a change of control may be uncertain.

RISKS RELATED TO OUR BUSINESS

  THE OIL AND NATURAL GAS MARKET IS VOLATILE AND THE PRICE OF OIL AND NATURAL
  GAS FLUCTUATES, WHICH MAY ADVERSELY AFFECT OUR CASH FLOWS AND THE VALUE OF OUR
  OIL AND NATURAL GAS RESERVES.

     Our future revenues and profits and the value of our oil and natural gas
reserves will depend substantially on the demand and prices we receive for
produced oil and natural gas. Oil and natural gas prices have been and are
likely to continue to be volatile in the future. The recent oil and natural gas
prices may not continue and could drop precipitously in a short period of time.

     The prices of oil and natural gas are subject to wide fluctuations in
response to a variety of factors beyond our control, including the following:

     - relatively minor changes in the supply of, and demand for, domestic and
       foreign oil and natural gas;

     - market uncertainty;

     - the ability of members of the Organization of Petroleum Exporting
       Countries to agree upon and maintain oil prices and production controls;

     - the level of consumer product demand;

     - political conditions in international oil-producing regions, such as the
       Middle East, Nigeria and Venezuela;

     - weather conditions;

     - domestic and foreign governmental regulations and taxes;

     - the price and availability of alternative fuels;

     - overall domestic and global economic conditions;

     - the price of oil and natural gas imports;

     - the effect of worldwide energy conservation measures; and

     - the proximity to and capacity of transportation facilities.
                                        16


     These external factors and the volatile nature of the energy markets make
it difficult to reliably estimate future prices of oil and natural gas.

     As oil and natural gas prices decline, we are affected in several ways:

     - we are paid less for our oil and natural gas, thereby reducing our cash
       flows;

     - exploration and development activity may decline as some projects may
       become uneconomic and either are delayed or eliminated;

     - our lenders could reduce the borrowing base under our bank credit
       facility because of lower oil and natural gas reserve values, thereby
       reducing our liquidity and possibly requiring mandatory loan repayments;
       and

     - access to other sources of capital, such as equity or long-term debt
       markets, could be severely limited or unavailable in a low price
       environment.

     Accordingly, any substantial or extended decline in oil or natural gas
prices may have material adverse effects on our cash flow, liquidity and
profitability and may cause us to be unable to meet our financial obligations or
make planned capital expenditures.

  WE MAY BE UNABLE TO SATISFY OUR FUTURE CAPITAL REQUIREMENTS.

     We make substantial capital expenditures in connection with the
acquisition, exploration and development of our oil and natural gas properties.
In the past, we have funded these capital expenditures with cash flow from
operations, funds from long-term debt financings, including bank financings
secured by our oil and natural gas assets, and funds from equity financings. Our
future cash flows are subject to a number of factors, some of which are beyond
our control, including the following:

     - the price of oil and natural gas;

     - the level of production from existing wells;

     - operating and development costs; and

     - our success in locating and producing new reserves.

     The availability of long-term debt and equity financing is also subject to
these factors. Investors in our debt securities view our future cash flow as a
measure of our ability to make principal and interest payments. In addition, the
availability of funds under our bank credit facility is based on the value of
our estimated oil and natural gas reserves and our cash flows, which in turn are
based on prices of oil and natural gas and the amount and timing of production.
Similarly, investors in our equity securities consider both the value of our oil
and natural gas properties and our cash flow in evaluating our prospects for
growth and profitability. If our future cash flows decrease, however, and we are
unable to obtain additional long-term debt or equity financing or our borrowing
base under our bank credit facility is re-determined to a lower amount, we may
be unable to satisfy our future capital requirements.

  WE MAY BE UNABLE TO SUCCESSFULLY IDENTIFY, EXECUTE OR EFFECTIVELY INTEGRATE
  FUTURE ACQUISITIONS, WHICH MAY NEGATIVELY AFFECT OUR RESULTS OF OPERATIONS.

     Acquisitions of oil and natural gas businesses and properties have been an
important element of our business, and we will continue to pursue acquisitions
in the future. In the last several years, we have pursued and consummated
acquisitions that allow us to drill development and extension wells. Although we
regularly engage in discussions with, and submit proposals to, acquisition
candidates, suitable acquisitions may not be available in the future on
reasonable terms as there is intense competition for acquisition opportunities
in our industry. If we do identify an appropriate acquisition candidate, we may
be unable to successfully negotiate the terms of an acquisition, finance the
acquisition or, if the acquisition occurs, effectively integrate the acquired
business into our existing business. Negotiations of potential acquisitions and
the integration of acquired business operations may require a disproportionate
amount of management's attention and our resources. Even

                                        17


if we complete additional acquisitions, continued acquisition financing may not
be available or available on reasonable terms, any new businesses may not
generate revenues comparable to our existing business, the anticipated cost
efficiencies or synergies may not be realized and these businesses may not be
integrated successfully or operated profitably. The success of any acquisition
will depend on a number of factors, many of which are beyond our control,
including:

     - the ability to estimate accurately the recoverable volumes of reserves;

     - the ability to estimate accurately rates of future production and future
       net revenues attainable from the reserves;

     - future oil and natural gas prices;

     - operating costs; and

     - the ability to estimate accurately potential environmental and other
       liabilities.

     Our inability to successfully identify, execute or effectively integrate
future acquisitions may negatively affect our results of operations. Even though
we perform a due diligence review (including a review of title and other
records) of the major properties we seek to acquire that we believe is
consistent with industry practices, these reviews are inherently incomplete. It
is generally not feasible for us to review in-depth every individual property
and all records involved in each acquisition. However, even an in-depth review
of records and properties may not necessarily reveal existing or potential
problems or permit us to become familiar enough with the properties to assess
fully their deficiencies and potential. Even when problems are identified, we
may not be able to obtain contractual indemnities from the sellers for
liabilities that it created and we may assume certain environmental and other
risks and liabilities in connection with the acquired businesses and properties.
The discovery of any material liabilities associated with our acquisitions could
harm our results of operations.

     In addition, acquisitions of businesses may require additional debt or
equity financing, resulting in additional leverage or dilution of ownership. Our
bank credit facility and the indenture governing our senior notes contain
certain covenants that limit, or which may have the effect of limiting, among
other things, acquisitions, capital expenditures, the sale of assets and the
incurrence of additional indebtedness.

  THERE ARE NUMEROUS UNCERTAINTIES INHERENT IN ESTIMATING QUANTITIES OF PROVED
  OIL AND NATURAL GAS RESERVES AND FUTURE NET REVENUES.

     The quantities and values of our proved reserves included in this annual
report and in the other documents we file with, or furnish to, the SEC are only
estimates and are subject to numerous uncertainties. Reserve estimating is a
subjective process of determining the size of underground accumulations of oil
and natural gas that cannot be measured in an exact manner. Estimates of
economically recoverable oil and natural gas reserves and of future net revenues
may vary considerably from the actual results because of a number of variable
factors and assumptions involved. These include:

     - the effects of regulation by governmental agencies;

     - future oil and natural gas prices;

     - operating costs;

     - the method by which the reservoir is produced as well as the properties
       of the rock;

     - relationships with landowners, working interest partners, pipeline
       companies and others;

     - severance and excise taxes;

     - development costs; and

     - workover and remedial costs.

     In addition, volumetric calculations are often used to estimate initial
reserves from a field. These estimates utilize data including the area that a
well is expected to drain, rock properties derived from log

                                        18


analysis, anticipated reservoir fluid properties, abandonment pressure and
estimates of recovery factors. As production data becomes available, the actual
performance is often used to project the final reserves. As such, initial
reserve estimates are much less precise in nature. The actual production,
revenues and expenditures related to our reserves may vary materially from the
engineers' estimates.

     Furthermore, we may make changes to our estimates of reserves and future
net revenues. These changes, which may be material, may be based on the
following factors:

     - well performance;

     - results of development including drilling and workovers;

     - oil and natural gas prices;

     - performance of counterparties under agreements to which we are a party;
       and

     - operating and development costs.

     Actual future net revenues may also be materially affected by the following
factors:

     - the amount and timing of actual production and costs incurred with such
       production;

     - the supply of, and demand for, oil and natural gas; and

     - the changes in governmental regulations or taxation.

     Ultimately, the timing in producing and the costs incurred in developing
and producing will affect the actual present value of oil and natural gas. In
addition, the SEC requires that we apply a 10% discount factor in calculating
PV-10 value for reporting purposes. This may not be the most appropriate
discount factor to apply because it does not take into account the interest
rates in effect, the risks associated with us and our properties, or the oil and
natural gas industry in general.

     For the foregoing reasons, you should not assume that the present value of
future net cash flows from our proved reserves referred to in this prospectus or
in our other reports filed with, or furnished to, the SEC is the current market
value of our estimated oil and natural gas reserves. In accordance with SEC
requirements, we base the estimated discounted future net cash flows from our
proved reserves on prices and costs on the date of the estimate. Actual prices
and costs since the date of the estimate and future prices and costs may differ
materially from those used in the net present value estimate, and as a result,
net present value estimates using current prices and costs may be significantly
more or less than the estimate which is provided in this prospectus or in our
other reports filed with, or furnished to, the SEC.

  OUR OPERATING ACTIVITIES INVOLVE SIGNIFICANT RISKS THAT ARE INHERENT IN THE
  OIL AND NATURAL GAS INDUSTRY, WHICH MAY RESULT IN SUBSTANTIAL LOSSES, AND
  INSURANCE MAY BE UNAVAILABLE OR INADEQUATE TO PROTECT US AGAINST THESE RISKS.

     Our operations are subject to numerous operating risks that are beyond our
control, are inherent in the oil and natural gas industry and could result in
substantial losses. These risks include:

     - fires;

     - natural disasters;

     - explosions;

     - well blowouts;

     - adverse weather conditions;

     - mechanical problems, including pipe failure;

     - abnormally pressured formations; and

     - environmental accidents, including oil spills, natural gas leaks or
       ruptures, or other discharges of toxic gases or other pollutants.

                                        19


     The occurrence of these risks could result in substantial losses due to
personal injury, loss of life, damage to or destruction of wells, production
facilities, natural resources or other property or equipment, pollution and
other environmental damage. These occurrences could also subject us to clean-up
obligations, regulatory investigation, penalties or suspension of operations.
Further, our operations may be materially curtailed, delayed or canceled as a
result of numerous factors, including:

     - unexpected drilling conditions;

     - the presence of unanticipated pressure or irregularities in formations;

     - equipment failures or accidents;

     - title problems;

     - weather conditions;

     - compliance with governmental requirements; and

     - costs of, shortages or delays in the availability of, drilling rigs or in
       the delivery of equipment and experienced labor.

     In accordance with customary industry practice, we maintain insurance
against some, but not all, of the risks described above. The levels of insurance
we maintain may not be adequate to fully cover any losses or liabilities. We may
not be able to maintain insurance at commercially acceptable premium levels or
at all. The occurrence of a significant event, not fully insured or indemnified
against, could have a material adverse effect on our financial condition and
operations.

  WE MAY BE UNABLE TO PRODUCE SUFFICIENT AMOUNTS OF OIL AND NATURAL GAS AND, AS
  A RESULT, OUR PROFITABILITY AND CASH FLOW WILL DECLINE.

     We may drill new wells that are not productive or we may not recover all or
any portion of our investment. Drilling for oil and natural gas may be
unprofitable due to a number of risks, including:

     - wells may not be productive, either because commercially productive
       reservoirs were not encountered or for other reasons;

     - wells that are productive may not provide sufficient net reserves to
       return a profit after taking into account leasehold, geophysical and
       geological, drilling, operating and other costs; and

     - the costs of drilling, completing and operating wells are often
       uncertain.

     If we are unable to produce sufficient amounts of oil and natural gas, our
profitability and cash flow will decline.

  IF WE ARE UNABLE TO ACQUIRE OR DISCOVER ADDITIONAL RESERVES, OUR RESERVES AND
  PRODUCTION WILL DECLINE MATERIALLY.

     Our prospects for future growth and profitability depend primarily on our
ability to replace oil and natural gas reserves through acquisitions and
exploratory and development drilling. Acquisitions may not be available at
attractive prices or at all. The decision to purchase, explore or develop a
property depends in part on geophysical and geological analyses and engineering
studies that are often inconclusive or subject to varying interpretations. As a
consequence, our acquisition, exploration and development activities may not
result in significant additional reserves or reserves that are economically
recoverable. Without the acquisition, discovery or development of additional
reserves, our proved reserves and production will decline materially.

  OUR FAILURE TO REMAIN COMPETITIVE WITH OUR NUMEROUS COMPETITORS, MANY OF WHICH
  HAVE SUBSTANTIALLY GREATER RESOURCES THAN WE DO, COULD ADVERSELY AFFECT OUR
  RESULTS OF OPERATIONS.

     The oil and natural gas industry is highly competitive in the search for,
and development and acquisition of, reserves and in the marketing of oil and
natural gas production. We compete with major oil and natural gas

                                        20


companies, other independent oil and natural gas concerns and individual
producers and operators in most aspects of our business, including the
following:

     - the acquisition of oil and natural gas businesses and properties;

     - the exploration, development, production and marketing of oil and natural
       gas;

     - the acquisition of properties and equipment; and

     - the hiring and retention of personnel necessary to explore for, develop,
       produce and market oil and natural gas.

     Many of these competitors have substantially greater financial and other
resources than we do. If we are unable to successfully compete against our
competitors, our business, prospects, financial condition and results of
operations may be adversely affected.

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

     Our business is subject to numerous federal, state and local laws and
regulations, including energy, environmental, conservation, tax and other laws
and regulations relating to the energy industry. We are subject to various
federal, state and local laws and regulations relating to the discharge of
materials into, and protection of, the environment. These laws and regulations
may, among other things:

     - limit drilling locations or the rate of allowable hydrocarbon production
       from a well;

     - affect the cost, terms and availability of oil and natural gas
       transportation by pipeline;

     - impose liability on us under an oil and natural gas lease for the cost of
       pollution clean-up and remediation resulting from operations;

     - impose liability on us for personal injuries and property damage;

     - subject us to liability for pollution damages, including oil spills,
       discharge of hazardous materials and reclamation costs; and

     - require suspension or cessation of operations in affected areas and
       subject the lessee to administrative, civil and criminal penalties.

     Any of these liabilities, penalties, suspensions, terminations or
regulatory changes could make it more expensive for us to conduct our business
or cause us to limit or curtail some of our operations.

     Environmental laws have in recent years become more stringent and have
generally sought to impose greater liability on a larger number of potentially
responsible parties. While we are not currently aware of any situation involving
an environmental claim that would likely have a material adverse effect on our
business, it is always possible that an environmental claim with respect to one
or more of our current properties or a business or property that one of our
predecessors owned or used could arise and could involve the expenditure of a
material amount of funds. Although we maintain insurance coverage which we
believe is customary in the industry, we are not fully insured against all
environmental risks.

     The Department of Transportation, through the Office of Pipeline Safety and
Research and Special Programs Administration, has implemented a series of rules
requiring operators of natural gas and hazardous liquid pipelines to develop
integrity management plans for pipelines that, in the event of failure, could
impact certain high consequence areas. These rules also require operators to
conduct baseline integrity assessments of all applicable pipeline segments
located in the high consequence areas. We continually are in the process of
identifying any of our pipeline segments that may be subject to these rules. We
have developed an integrity management plan for all covered pipeline segments.
We do not expect to incur significant costs in achieving compliance with these
rules.

     Further, hydrocarbon-producing states regulate conservation practices and
the protection of correlative rights. These regulations affect our operations
and limit the quantity of hydrocarbons we may produce and sell.
                                        21


     The oil and natural gas regulatory environment could change in ways that
could substantially increase the cost of complying with the requirements of
environmental and other regulations. We cannot predict whether, or when, new
laws and regulations may be enacted or adopted, and we cannot predict the cost
of compliance with changing laws and regulations or their effects on oil and
natural gas use or prices.

  WE HAVE LIMITED CONTROL OVER THE ACTIVITIES ON PROPERTIES THAT WE DO NOT
  OPERATE, WHICH COULD HAVE A MATERIAL ADVERSE EFFECT ON THE REALIZATION OF OUR
  TARGETED RETURNS OR LEAD TO UNEXPECTED FUTURE COSTS.

     Although we operate most of the properties in which we have an interest,
other companies operate some of the properties. We have limited ability to
influence or control the operation or future development of these non-operated
properties or the amount of capital expenditures that we are required to fund
for their operation. Our dependence on the operator and other working interest
owners for these projects and our limited ability to influence or control the
operation and future development of these properties could have a material
adverse effect on the number of wells we drill, realization of our targeted
returns or lead to unexpected future costs.

  THE CONCENTRATION OF OUR CUSTOMERS IN THE ENERGY INDUSTRY COULD INCREASE OUR
  EXPOSURE TO CREDIT RISK, WHICH COULD RESULT IN LOSSES.

     The concentration of our customers in the energy industry may impact our
overall exposure to credit risk, either positively or negatively, in that
customers may be similarly affected by prolonged changes in economic and
industry conditions. We perform ongoing credit evaluations of our customers and
do not generally require collateral in support of our trade receivables. We
maintain reserves for credit losses and, generally, actual losses have been
consistent with our expectations, with the exception of losses we sustained
relating to obligations of certain Enron entities to us.

  IF WE ARE UNSUCCESSFUL TRANSPORTING OUR OIL AND NATURAL GAS TO MARKET AT
  COMMERCIALLY ACCEPTABLE PRICES, OUR PROFITABILITY WILL DECLINE.

     We deliver oil and natural gas through gathering systems and pipelines that
we do not own. Our ability to transport our oil and natural gas to market at
commercially acceptable prices or at all depends on, among other factors, the
following:

     - the availability, proximity and capacity of third-party gathering
       systems, processing facilities and pipelines;

     - changes in supply and demand; and

     - general economic conditions.

     Our inability to respond appropriately to changes in any of the foregoing
factors could negatively affect our profitability.

     In addition, the transportation by pipeline of oil and natural gas in
interstate commerce is heavily regulated by the FERC, including regulation of
the cost, terms and conditions for such transportation service, and in the case
of natural gas, the construction and location of pipelines. The transportation
by pipeline of oil and natural gas in intrastate commerce is generally subject
to varying degrees of state regulation of the cost, terms and conditions of
service. While we are not directly subject to these regulations, they affect the
cost and availability of transportation of our production to market.

  UNINSURED JUDGMENTS OR A RISE IN INSURANCE PREMIUMS MAY ADVERSELY IMPACT OUR
  RESULTS OF OPERATIONS.

     Exploration for, and production of, oil and natural gas can be hazardous,
involving unforeseen occurrences. Accordingly, in the ordinary course of
business, we are subject to various claims and litigation. Although we maintain
insurance to cover certain potential claims and losses arising from our
operations in accordance with customary industry practices and in amounts that
management believes to be prudent, we could become subject to a judgment for
which we are not adequately insured and beyond the amounts that we currently
have reserved or anticipate reserving. Additionally, the terrorist attacks of
September 11, 2001 and the continued hostilities in the Middle East and other
sustained military campaigns may adversely impact our

                                        22


ability to obtain insurance or impact the cost of this insurance, either of
which may adversely impact our results of operations.

  TERRORIST ATTACKS AND CONTINUED HOSTILITIES IN THE MIDDLE EAST OR OTHER
  SUSTAINED MILITARY CAMPAIGNS MAY ADVERSELY IMPACT OUR FINANCIAL CONDITION AND
  OPERATIONS.

     The terrorist attacks that took place in the United States on September 11,
2001 were unprecedented events that have created many economic and political
uncertainties, some of which may materially adversely impact our business. The
continued threat of terrorism and the impact of military and other action,
including U.S. military operations in Iraq, will likely lead to continued
volatility in prices for crude oil and natural gas and could affect the markets
for our operations. In addition, future acts of terrorism could be directed
against companies operating in the United States. The United States government
has issued public warnings that indicate that energy assets might be specific
targets of terrorist organizations. These developments have subjected our
operations, and those of our purchasers, to increased risks and, depending on
their ultimate magnitude, may adversely impact our financial condition and
operations.

  OUR SUCCESS DEPENDS ON KEY MEMBERS OF SENIOR MANAGEMENT, THE LOSS OF WHOM
  COULD DISRUPT OUR CUSTOMER RELATIONSHIPS AND BUSINESS OPERATIONS.

     We believe our continued success depends in large part on the sustained
contributions of our chief executive officer and chairman of the board of
directors, James W. Christmas, our president and chief operating officer,
William N. Hahne, and our management team and technical personnel. We rely on
our executive officers and senior management to identify and pursue new business
opportunities and identify key growth opportunities. In addition, the
relationships and reputation that members of our management team have
established and maintained in the oil and natural gas community contribute to
our ability to maintain positive customer relations and to identify new business
opportunities. The loss of services of Messrs. Christmas or Hahne or one or more
senior management or technical staff could significantly impair our ability to
identify and secure new business opportunities and otherwise disrupt operations.
We do not maintain key person life insurance on any of our senior management
members.

  WE ENGAGE IN HEDGING TRANSACTIONS, WHICH MAY LIMIT OUR POTENTIAL GAINS AND
  EXPOSE US TO RISK OF FINANCIAL LOSS.

     We periodically purchase or sell derivative instruments covering a portion
of our expected production in order to manage our exposure to price risk in
marketing our oil and natural gas. These instruments may include futures
contracts and options sold on the New York Mercantile Exchange and privately
negotiated forwards, swaps and options. These transactions may limit our
potential gains if oil and natural gas prices were to rise substantially over
the prices established by hedging. These transactions also may expose us to the
risk of financial loss in certain circumstances, including the following:

     - production is less than the volume hedged;

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

     - the counterparties to our derivative instruments fail to perform their
       contract obligations;

     - we fail to make timely deliveries; and

     - a sudden, unexpected event materially impacts oil or natural gas prices.

  SHORTAGE OF DRILLING RIGS, EQUIPMENT, SUPPLIES OR PERSONNEL MAY DELAY OR
  RESTRICT OUR OPERATIONS.

     The oil and natural gas industry is cyclical and, from time to time, there
is a shortage of drilling rigs, equipment, supplies or personnel. During these
periods, the costs and delivery times of drilling rigs, equipment and supplies
are substantially greater. In addition, demand for, and wage rates of, qualified
drilling rig crews rise with increases in the number of active rigs in service.
Shortages of drilling rigs, equipment, supplies or personnel may increase
drilling costs or delay or restrict our exploration and development operations,
which in turn could impair our financial condition and results of operations.

                                        23


                       RATIO OF EARNINGS TO FIXED CHARGES

     The following table sets forth our consolidated ratio of earnings to fixed
charges for the periods shown:

Ratio of earnings to fixed charges.....  1.97x  3.50x  1.43x  3.20x  6.49x      8.88x
</Table>

     The ratio was computed by dividing earnings by fixed charges. For this
purpose, "earnings" represent the aggregate of pre-tax income from continuing
operations before reorganization items and cumulative effect of accounting
change plus fixed charges excluding capitalized interest. "Fixed charges"
include interest expensed, capitalized interest, amortization of debt issuance
costs and the portion of non-capitalized rental expense deemed to be the
equivalent of interest.

                                USE OF PROCEEDS

     The exchange offer is intended to satisfy our obligations under the
registration rights agreement we entered into in connection with the private
offering of the old notes. We will not receive any proceeds from the issuance of
the new notes in the exchange offer. In consideration for issuing the new notes
as contemplated in this prospectus, we will receive, in exchange, outstanding
old notes in like principal amount. We will cancel all old notes surrendered in
exchange for new notes in the exchange offer. As a result, the issuance of the
new notes will not result in any increase or decrease in our indebtedness.

     The net proceeds from the offering of the sale of the old notes in the
initial private placement were approximately $98.2 million in the aggregate
after deducting estimated expenses of the offering. Approximately $82.2 million
of the net proceeds to us from the sale of the old notes, along with
approximately $4.7 million paid as a deposit in February 2005, was used to
finance our acquisition of oil and gas properties and related assets located
primarily in our North Louisiana -- East Texas core operating area. The
remainder of the net proceeds to us from the sale of the old notes was used to
repay approximately $16.0 million of indebtedness under our bank credit
facility. Please read "Prospectus Summary -- Recent Developments -- Oil and Gas
Property Acquisition" for more information on our recent acquisition.

     The indebtedness under our bank credit facility had an average interest
rate of 5.75% at March 31, 2005. The bank credit facility matures on March 31,
2009. During the last year, funds were drawn from time to time on our bank
credit facility to accelerate our drilling program and for general corporate
purposes.

    allowance on our net deferred tax assets and a $6.2 million non-cash charge
    for the cumulative effect of an accounting change related to the
    amortization method of oil and gas properties.

(2) Includes a $20.2 million income tax benefit related to the reversal of a
    portion of our valuation allowance against net deferred tax assets and a
    $0.9 million non-cash charge related to the cumulative effect of an
    accounting change as a result of the adoption of SFAS No. 143, "Accounting

    remaining portion of our valuation allowance against net deferred tax
    assets.

    continuing operations before reorganization items and cumulative effect of
    accounting change plus fixed charges excluding capitalized interest. "Fixed
    charges" include interest expensed, capitalized interest, amortization of
    debt issuance costs and that portion of non-capitalized rental expense
    deemed to be the equivalent of interest.

                       DESCRIPTION OF OTHER INDEBTEDNESS

     On March 31, 2005, we amended our amended and restated bank credit facility
with a group of commercial bank lenders. The bank credit facility, as amended,
provides up to $250.0 million of revolving borrowing capacity, matures on March
31, 2009 and permits $25.0 million of indebtedness for money borrowed (in
addition to the $175.0 million of previously issued notes and the $100.0 million
of old notes). Borrowing capacity under the bank credit facility, as amended, is
subject to a borrowing base initially set at $185.0 million and is reviewed at
least semi-annually and may be adjusted based on the lenders' valuation of our
oil and gas reserves and other factors. The borrowing base will automatically be
reduced by an amount equal to a specified percentage of the net proceeds from
the issuance of additional indebtedness that is not applied to refinance
existing indebtedness. As a result of the application of this provision, upon
the issuance of the old notes, the borrowing base was automatically reduced by
$20.0 million to $165.0 million. Substantially all of our assets, including the
stock of all of our subsidiaries, are pledged to secure the bank credit
facility. Further, each of our subsidiaries has guaranteed our obligations under
the bank credit facility.

     Borrowings under the bank credit facility bear interest, at our option, at
an interest rate of LIBOR plus 1.75% to 2.50%, depending on utilization, or the
greater of (1) the Federal Funds Rate plus 0.50% or (2) the Base Rate, plus
0.00% to 0.75%, depending on utilization. The margin for LIBOR and Base Rate
loans will decrease by 0.50% (but not below 0.0%), after the final deliveries
are made in January 2006 in connection with the Production Payment discussed in
Note 1 to our consolidated financial statements included in our annual report on
Form 10-K for the fiscal year ended December 31, 2004 incorporated herein by
reference and the lien on the subject properties is released. A commitment fee
of 0.35% to 0.50% per year, depending on utilization, is paid on the unused
availability under the bank credit facility.

     The bank credit facility contains various restrictive covenants and other
usual and customary terms and conditions of a conventional borrowing base
facility, prohibitions on a change of control, prohibitions on the payment of
cash dividends, restrictions on certain other distributions and restricted
payments, and limitations on the incurrence of additional debt and the sale of
assets. The bank credit facility also provides for us to comply with certain
financial covenants including, among other things:

     - maintaining a ratio of Adjusted EBITDA (earnings before interest, taxes,
       depreciation, depletion, amortization, other non-cash charges and
       exploration expenses minus amortization of deferred revenue attributable
       to Production Payment sold in February 2001) to cash interest payments of
       at least 2.50 to 1.00;

     - maintaining a ratio of consolidated current assets plus unused
       availability under our credit facility to consolidated current
       liabilities (excluding the current portion of indebtedness for borrowed
       money and the face amount of letters of credit) of not less than 1.00 to
       1.00; and

     - not entering into hedging transactions covering more than 80% of
       projected production from our proved developed producing reserves for the
       period of such transactions.

     The bank credit facility also contains customary events of default,
including any defaults by us in the payment or performance of any other
indebtedness equal to or exceeding $5.0 million.

     As of March 31, 2005, the outstanding balance under our bank credit
facility was approximately $13.0 million and there was approximately $172.0
million available for additional borrowings. We were also in compliance with all
covenants under the bank credit facility as of that date. After giving effect to
the issuance of the old notes and the consummation of our acquisition of oil and
gas properties and related assets located primarily in our North
Louisiana -- East Texas core operating area and the application of the net
proceeds to us from the issuance of the old notes, we would have had no amounts
outstanding under our bank credit facility as of March 31, 2005. As of June 30,
2005, we had $15.0 million outstanding under the bank credit facility.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     On April 8, 2005, we sold $100.0 million in aggregate principal amount at
maturity of the old notes in a private placement. The old notes were sold to the
initial purchasers who in turn resold the notes to a limited number of qualified
institutional buyers pursuant to Rule 144A of the Securities Act.

     In connection with the sale of the old notes, we entered into a
registration rights agreement with the initial purchasers of the old notes,
pursuant to which we agreed to file and to use our reasonable best efforts to
cause to be declared effective by the SEC a registration statement with respect
to the exchange of the old notes for the new notes. We are making the exchange
offer to fulfill our contractual obligations under that agreement. A copy of the
registration rights agreement has been filed as an exhibit to the registration
statement of which this prospectus is a part.

     Pursuant to the exchange offer, we will issue the new notes in exchange for
old notes. The terms of the new notes are identical in all material respects to
those of the old notes, except that the new notes (1) have been registered under
the Securities Act and therefore will not be subject to certain restrictions on
transfer applicable to the old notes and (2) will not have registration rights
or provide for any additional interest related to the obligation to register.
Please read "Description of the New Notes" for more information on the terms of
the respective notes and the differences between them.

     We are not making the exchange offer to, and will not accept tenders for
exchange from, holders of old notes in any jurisdiction in which an exchange
offer or the acceptance thereof would not be in compliance with the securities
or blue sky laws of such jurisdiction. Unless the context requires otherwise,
the term "holder" with respect to the exchange offer means any person in whose
name the old notes are registered on our books or any other person who has
obtained a properly completed bond power from the registered holder, or any
person whose old notes are held of record by The Depository Trust Company,
referred to as DTC, who desires to deliver such old notes by book-entry transfer
at DTC.

     We make no recommendation to the holders of old notes as to whether to
tender or refrain from tendering all or any portion of their old notes pursuant
to the exchange offer. In addition, no one has been authorized to make any such
recommendation. Holders of old notes must make their own decision whether to
tender pursuant to the exchange offer and, if so, the aggregate amount of old
notes to tender after reading this prospectus and the letter of transmittal and
consulting with the advisers, if any, based on their own financial position and
requirements.

     In order to participate in the exchange offer, you must represent to us,
among other things, that:

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

     - you are not engaged in, and do not intend to engage in, a distribution of
       the new notes;

     - you do not have and to your knowledge, no one receiving new notes from
       you has, any arrangement or understanding with any person to participate
       in the distribution of the new notes;

     - you are not a broker-dealer tendering old notes acquired directly from us
       for your own account or if you are a broker-dealer, you will comply with
       the prospectus delivery requirements of the Securities Act in connection
       with any resale of the new notes; and

     - you are not one of our "affiliates," as defined in Rule 405 of the
       Securities Act.

     Each broker-dealer that receives new 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 such new
notes. Please read "Plan of Distribution."

                                        31


TERMS OF EXCHANGE

     Upon the terms and conditions described in this prospectus and in the
accompanying letter of transmittal, which together constitute the exchange
offer, we will accept for exchange old notes that are properly tendered at or
before the expiration time and not withdrawn as permitted below. As of the date
of this prospectus, $275.0 million aggregate principal amount of 7 1/8% Senior
Notes due 2012 are outstanding. This prospectus, together with the letter of
transmittal, is first being sent on or about the date on the cover page of the
prospectus to all holders of old notes known to us. Old notes tendered in the
exchange offer must be in denominations of principal amount of $1,000 and any
integral multiple of $1,000.

     Our acceptance of the tender of old notes by a tendering holder will form a
binding agreement between the tendering holder and us upon the terms and subject
to the conditions provided in this prospectus and in the accompanying letter of
transmittal.

     The form and terms of the new notes being issued in the exchange offer are
the same as the form and terms of the old notes except that:

     - the new notes being issued in the exchange offer will have been
       registered under the Securities Act;

     - the new notes being issued in the exchange offer will not bear the
       restrictive legends restricting their transfer under the Securities Act;
       and

     - the new notes being issued in the exchange offer will not contain the
       registration rights contained in the old notes.

EXPIRATION, EXTENSION AND AMENDMENT

     The expiration time of the exchange offer is 5:00 P.M., New York City time,
on           , 2005. However, we may, in our sole discretion, extend the period
of time for which the exchange offer is open and set a later expiration date for
the offer. The term "expiration time" as used herein means the latest time and
date to which we extend the exchange offer. If we decide to extend the exchange
offer period, we will then delay acceptance of any old notes by giving oral or
written notice of an extension to the holders of old notes as described below.
During any extension period, all old notes previously tendered will remain
subject to the exchange offer and may be accepted for exchange by us. Any old
notes not accepted for exchange will be returned to the tendering holder after
the expiration or termination of the exchange offer.

     Our obligation to accept old notes for exchange in the exchange offer is
subject to the conditions described below under "-- Conditions to the Exchange
Offer." We may decide to waive any of the conditions in our discretion.
Furthermore, we reserve the right to amend or terminate the exchange offer, and
not to accept for exchange any old notes not previously accepted for exchange,
upon the occurrence of any of the conditions of the exchange offer specified
below under the same heading. 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 materially change the terms of the
exchange offer, we will resolicit tenders of the old notes, file a
post-effective amendment to the prospectus and provide notice to you. If the
change is made less than five business days before the expiration of the
exchange offer, we will extend the offer so that the holders have at least five
business days to tender or withdraw. We will notify you of any extension by
means of a press release or other public announcement no later than 9:00 A.M.,
New York City time, on the first business day after the previously scheduled
expiration time.

                                        32


PROCEDURES FOR TENDERING

  VALID TENDER

     Except as described below, a tendering holder must, prior to the expiration
time, transmit to The Bank of New York Trust Company, N.A., the exchange agent,
at the address listed below under the caption "-- Exchange Agent":

     - a properly completed and duly executed letter of transmittal, including
       all other documents required by the letter of transmittal; or

     - if old notes are tendered in accordance with the book-entry procedures
       listed below, an agent's message transmitted through DTC's Automated
       Tender Offer Program, referred to as ATOP.

     In addition, you must:

     - deliver certificates, if any, for the old notes to the exchange agent at
       or before the expiration time; or

     - deliver a timely confirmation of the book-entry transfer of the old notes
       into the exchange agent's account at DTC, the book-entry transfer
       facility, along with the letter of transmittal or an agent's message; or

     - comply with the guaranteed delivery procedures described below.

     The term "agent's message" means a message, transmitted by DTC to, and
received by, the exchange agent and forming a part of a book-entry confirmation,
that states that DTC has received an express acknowledgment that the tendering
holder agrees to be bound by the letter of transmittal and that we may enforce
the letter of transmittal against such holder.

     If the letter of transmittal is signed by a person other than the
registered holder of old notes, the letter of transmittal must be accompanied by
a written instrument of transfer or exchange in satisfactory form duly executed
by the registered holder with the signature guaranteed by an eligible
institution. The old notes must be endorsed or accompanied by appropriate powers
of attorney. In either case, the old notes must be signed exactly as the name of
any registered holder appears on the old notes.

     If the letter of transmittal or any old notes or powers of attorney 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 waived by us,
proper evidence satisfactory to us of their authority to so act must be
submitted.

     By tendering, each holder will represent to us that, among other things,
the person is not our affiliate, the new notes are being acquired in the
ordinary course of business of the person receiving the new notes, whether or
not that person is the holder, and neither the holder nor the other person has
any arrangement or understanding with any person to participate in the
distribution of the new notes. Each broker-dealer that receives new 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 such new notes. Please read "Plan of Distribution."

     The method of delivery of old notes, letters of transmittal and all other
required documents is at your election and risk, and the delivery will be deemed
made only upon actual receipt or confirmation by the exchange agent. If the
delivery is by mail, we recommend that you use registered mail, properly
insured, with return receipt requested. In all cases, you should allow
sufficient time to assure timely delivery. Holders tendering through DTC's ATOP
system should allow sufficient time for completion of the ATOP procedures during
the normal business hours of DTC on such dates.

     No old notes, agent's messages, letters of transmittal or other required
documents should be sent to us. Delivery of all old notes, agent's messages,
letters of transmittal and other documents must be made to the exchange agent.
Holders may also request their respective brokers, dealers, commercial banks,
trust companies or nominees to effect such tender for such holders.

                                        33


     If you are a beneficial owner whose old notes are registered in the name of
a broker, dealer, commercial bank, trust company or other nominee, and wish to
tender, you should promptly instruct the registered holder to tender on your
behalf. Any registered holder that is a participant in DTC's ATOP system may
make book-entry delivery of the old notes by causing DTC to transfer the old
notes into the exchange agent's account. The tender by a holder of old notes,
including pursuant to the delivery of an agent's message through DTC's ATOP
system, will constitute an agreement between such holder and us in accordance
with the terms and subject to the conditions set forth herein and in the letter
of transmittal.

     All questions as to the validity, form, eligibility, time of receipt and
withdrawal of the tendered old notes will be determined by us in our sole
discretion, which determination will be final and binding. We reserve the
absolute right to reject any and all old notes not validly tendered or any old
notes which, if accepted, would, in the opinion of our counsel, be unlawful. We
also reserve the absolute right to waive any irregularities or conditions of
tender as to particular old notes. Our interpretation of the terms and
conditions of this exchange offer, including the instructions in the letter of
transmittal, will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of old notes must be cured
within such time as we shall determine. Although we intend to notify you of
defects or irregularities with respect to tenders of old notes, none of us, the
exchange agent, or any other person shall be under any duty to give notification
of defects or irregularities with respect to tenders of old notes, nor shall any
of them incur any liability for failure to give such notification. Tenders of
old notes will not be deemed to have been made until such irregularities have
been cured or waived. Any old notes received by the exchange agent that are not
validly tendered and as to which the defects or irregularities have not been
cured or waived will be returned without cost to such holder by the exchange
agent, unless otherwise provided in the letter of transmittal, as soon as
practicable following the expiration date of the exchange offer.

     Although we have no present plan to acquire any old notes that are not
tendered in the exchange offer or to file a registration statement to permit
resales of any old notes that are not tendered in the exchange offer, we reserve
the right, in our sole discretion, to purchase or make offers for any old notes
after the expiration date of the exchange offer, from time to time, through open
market or privately negotiated transactions, one or more additional exchange or
tender offers, or otherwise, as permitted by law, the indenture and our other
debt agreements. Following consummation of this exchange offer, the terms of any
such purchases or offers could differ materially from the terms of this exchange
offer.

  SIGNATURE GUARANTEES

     Signatures on a letter of transmittal or a notice of withdrawal must be
guaranteed, unless the old notes surrendered for exchange are tendered:

     - by a registered holder of the old notes who has not completed the box
       entitled "Special Issuance Instructions" or "Special Delivery
       Instructions" on the letter of transmittal, or

     - for the account of an "eligible institution."

     If signatures on a letter of transmittal or a notice of withdrawal are
required to be guaranteed, the guarantees must be by an "eligible institution."
An "eligible institution" is an "eligible guarantor institution" meeting the
requirements of the registrar for the notes within the meaning of Rule 17Ad-15
under the Exchange Act.

  BOOK-ENTRY TRANSFER

     The exchange agent will make a request to establish an account for the old
notes at DTC for purposes of the exchange offer. Any financial institution that
is a participant in DTC's system may make book-entry delivery of old notes by
causing DTC to transfer those old notes into the exchange agent's account at DTC
in accordance with DTC's procedure for transfer. The participant should transmit
its acceptance to DTC at or prior to the expiration time or comply with the
guaranteed delivery procedures described below. DTC will verify this acceptance,
execute a book-entry transfer of the tendered old notes into the exchange
agent's account at DTC and then send to the exchange agent confirmation of this
book-entry transfer. The confirmation of this book-entry transfer will include
an agent's message confirming that DTC has received an

                                        34


express acknowledgment from this participant that this participant has received
and agrees to be bound by the letter of transmittal and that we may enforce the
letter of transmittal against this participant.

     Delivery of new notes issued in the exchange offer may be effected through
book-entry transfer at DTC. However, the letter of transmittal or facsimile of
it or an agent's message, with any required signature guarantees and any other
required documents, must:

     - be transmitted to and received by the exchange agent at the address
       listed under "-- Exchange Agent" at or prior to the expiration time; or

     - comply with the guaranteed delivery procedures described below.

     Delivery of documents to DTC in accordance with DTC's procedures does not
constitute delivery to the exchange agent.

  GUARANTEED DELIVERY

     If a registered holder of old notes desires to tender the old notes, and
the old notes are not immediately available, or time will not permit the
holder's old notes or other required documents to reach the exchange agent
before the expiration time, or the procedures for book-entry transfer described
above cannot be completed on a timely basis, a tender may nonetheless be made
if:

     - the tender is made through an eligible institution;

     - prior to the expiration time, the exchange agent receives by facsimile
       transmission, mail or hand delivery from such eligible institution a
       properly and validly completed and duly executed notice of guaranteed
       delivery, substantially in the form provided by us:

         1. stating the name and address of the holder of old notes and the
            amount of old notes tendered,

         2. stating that the tender is being made, and

         3. guaranteeing that within three New York Stock Exchange trading days
            after the expiration time, the certificates for all physically
            tendered old notes, in proper form for transfer, or a book-entry
            confirmation, as the case may be, and a properly completed and duly
            executed letter of transmittal, or an agent's message, and any other
            documents required by the letter of transmittal will be deposited by
            the eligible institution with the exchange agent; and

     - the certificates for all physically tendered old notes, in proper form
       for transfer, or a book-entry confirmation, as the case may be, and a
       properly completed and duly executed letter of transmittal, or an agent's
       message, and all other documents required by the letter of transmittal,
       are received by the exchange agent within three New York Stock Exchange
       trading days after the date of execution of the notice of guaranteed
       delivery.

  DETERMINATION OF VALIDITY

     We will determine in our sole discretion all questions as to the validity,
form and eligibility of old notes tendered for exchange. This discretion extends
to the determination of all questions concerning the timing of receipts and
acceptance of tenders. These determinations will be final and binding. We
reserve the right to reject any particular old note not properly tendered or of
which our acceptance might, in our judgment or our counsel's judgment, be
unlawful. We also reserve the right to waive any defects or irregularities or
conditions of the exchange offer as to any particular old note either before or
after the expiration time, including the right to waive the ineligibility of any
tendering holder. Our interpretation of the terms and conditions of the exchange
offer as to any particular old note either before or after the applicable
expiration time, including the letter of transmittal and the instructions to the
letter of transmittal, shall be final and binding on all parties. Unless waived,
any defects or irregularities in connection with tenders of old notes must be
cured within a reasonable period of time.

                                        35


     Neither we, the exchange agent nor any other person will be under any duty
to give notification of any defect or irregularity in any tender of old notes.
Moreover, neither we, the exchange agent nor any other person will incur any
liability for failing to give notifications of any defect or irregularity.

ACCEPTANCE OF OLD NOTES FOR EXCHANGE; ISSUANCE OF NEW NOTES

     Upon the terms and subject to the conditions of the exchange offer, we will
accept, promptly after the expiration time, all old notes properly tendered. We
will issue the new notes promptly after acceptance of the old notes. For
purposes of an exchange offer, we will be deemed to have accepted properly
tendered old notes for exchange when, as and if we have given oral or written
notice to the exchange agent, with prompt written confirmation of any oral
notice.

     For each old note accepted for exchange, the holder will receive a new note
registered under the Securities Act having a principal amount equal to that of
the surrendered old note. As a result, registered holders of old notes issued in
the exchange offer on the relevant record date for the first interest payment
date following the completion of the exchange offer will receive interest
accruing from the most recent date to which interest has been paid on the old
notes or, if no interest has been paid on the old notes, from April 1, 2005. Old
notes that we accept for exchange will cease to accrue interest from and after
the date of completion of the exchange offer. Under the registration rights
agreement, we may be required to make additional payments in the form of
additional interest to the holders of the old notes under circumstances relating
to the timing of the exchange offer.

     In all cases, issuance of new notes for old notes will be made only after
timely receipt by the exchange agent of:

     - certificate for the old notes, or a timely book-entry confirmation of the
       old notes, into the exchange agent's account at the book-entry transfer
       facility;

     - a properly completed and duly executed letter of transmittal or an
       agent's message; and

     - all other required documents.

     Unaccepted or non-exchanged old notes will be returned without expense to
the tendering holder of the old notes. In the case of old notes tendered by
book-entry transfer in accordance with the book-entry procedures described
above, the non-exchanged old notes will be credited to an account maintained
with DTC as promptly as practicable after the expiration or termination of the
exchange offer. For each old note accepted for exchange, the holder of the old
note will receive a new note having a principal amount equal to that of the
surrendered old note.

INTEREST PAYMENTS ON THE NEW NOTES

     The new notes will bear interest from the most recent date to which
interest has been paid on the old notes for which they were exchanged.
Accordingly, registered holders of new notes on the relevant record date for the
first interest payment date following the completion of the exchange offer will
receive interest accruing from the most recent date to which interest has been
paid. Old notes accepted for exchange will cease to accrue interest from and
after the date of completion of the exchange offer and will be deemed to have
waived their rights to receive the accrued interest on the old notes.

WITHDRAWAL RIGHTS

     Tender of old notes may be properly withdrawn at any time before 5:00 p.m.,
New York City time, on the expiration date of the exchange offer.

     For a withdrawal to be effective with respect to old notes, the exchange
agent must receive a written notice of withdrawal before the expiration time
delivered by hand, overnight by courier or by mail, at the

                                        36


address indicated under "-- Exchange Agent" or, in the case of eligible
institutions, at the facsimile number, or a properly transmitted "Request
Message" through DTC's ATOP system. Any notice of withdrawal must:

     - specify the name of the person, referred to as the depositor, having
       tendered the old notes to be withdrawn;

     - identify the old notes to be withdrawn, including certificate numbers and
       principal amount of the old notes;

     - contain a statement that the holder is withdrawing its election to have
       the old notes exchanged;

     - other than a notice transmitted through DTC's ATOP system, be signed by
       the holder in the same manner as the original signature on the letter of
       transmittal by which the old notes were tendered, including any required
       signature guarantees, or be accompanied by documents of transfer to have
       the trustee with respect to the old notes register the transfer of the
       old notes in the name of the person withdrawing the tender; and

     - specify the name in which the old notes are registered, if different from
       that of the depositor.

     If certificates for old notes have been delivered or otherwise identified
to the exchange agent, then, prior to the release of these certificates the
withdrawing holder must also submit the serial numbers of the particular
certificates to be withdrawn and signed notice of withdrawal with signatures
guaranteed by an eligible institution, unless this holder is an eligible
institution. If old notes have been tendered in accordance with the procedure
for book-entry transfer described below, any notice of withdrawal must specify
the name and number of the account at the book-entry transfer facility to be
credited with the withdrawn old notes.

     Any old notes properly withdrawn will be deemed not to have been validly
tendered for exchange. New notes will not be issued in exchange unless the old
notes so withdrawn are validly re-tendered.

     Properly withdrawn old notes may be re-tendered by following the procedures
described under "-- Procedures for Tendering" above at any time at or before the
expiration time.

     We will determine all questions as to the validity, form and eligibility,
including time of receipt, of notices of withdrawal.

CONDITIONS TO THE EXCHANGE OFFER

     Notwithstanding any other provisions of the exchange offer, or any
extension of the exchange offer, we will not be required to accept for exchange,
or to exchange, any old notes for any new notes, and, as described below, may
terminate an exchange offer, whether or not any old notes have been accepted for
exchange, or may waive any conditions to or amend the exchange offer, if any of
the following conditions has occurred or exists:

     - there shall occur a change in the current interpretation by the staff of
       the SEC which permits the new notes issued pursuant to such exchange
       offer in exchange for old notes to be offered for resale, resold and
       otherwise transferred by the holders (other than broker-dealers and any
       holder which is an affiliate) without compliance with the registration
       and prospectus delivery provisions of the Securities Act, provided that
       such new notes are acquired in the ordinary course of such holders'
       business and such holders have no arrangement or understanding with any
       person to participate in the distribution of the new notes;

     - any action or proceeding shall have been instituted or threatened in any
       court or by or before any governmental agency or body seeking to enjoin,
       make illegal or delay completion of the exchange offer or otherwise
       relating to the exchange offer;

     - any law, statute, rule or regulation shall have been adopted or enacted
       which, in our judgment, would reasonably be expected to impair our
       ability to proceed with such exchange offer;

     - a banking moratorium shall have been declared by United States federal or
       New York State authorities;
                                        37


     - trading on the New York Stock Exchange or generally in the United States
       over-the-counter market shall have been suspended, or a limitation on
       prices for securities imposed, by order of the SEC or any other
       governmental authority;

     - an attack on the United States, an outbreak or escalation of hostilities
       or acts of terrorism involving the United States, or any declaration by
       the United States of a national emergency or war shall have occurred;

     - a stop order shall have been issued by the SEC or any state securities
       authority suspending the effectiveness of the registration statement of
       which this prospectus is a part or proceedings shall have been initiated
       or, to our knowledge, threatened for that purpose or any governmental
       approval has not been obtained, which approval we shall, in our sole
       discretion, deem necessary for the consummation of such exchange offer;
       or

     - any change, or any development involving a prospective change, in our
       business or financial affairs or any of our subsidiaries has occurred
       which is or may be adverse to us or we shall have become aware of facts
       that have or may have an adverse impact on the value of the old notes or
       the new notes, which in our sole judgment in any case makes it
       inadvisable to proceed with such exchange offer and/or with such
       acceptance for exchange or with such exchange.

     If we determine in our sole discretion that any of the foregoing events or
conditions has occurred or exists, we may, subject to applicable law, terminate
the exchange offer, whether or not any old notes have been accepted for
exchange, or may waive any such condition or otherwise amend the terms of such
exchange offer in any respect. Please read "-- Expiration, Extension and
Amendment" above.

     If any of the above events occur, we may:

     - terminate the exchange offer and promptly return all tendered old notes
       to tendering holders;

     - complete and/or extend the exchange offer and, subject to your withdrawal
       rights, retain all tendered old notes until the extended exchange offer
       expires;

     - amend the terms of the exchange offer; or

     - waive any unsatisfied condition and, subject to any requirement to extend
       the period of time during which the exchange offer is open, complete the
       exchange offer.

     We may assert these conditions with respect to the exchange offer
regardless of the circumstances giving rise to them. All conditions to the
exchange offer, other than those dependent upon receipt of necessary government
approvals, must be satisfied or waived by us before the expiration of the
exchange offer. We may waive any condition in whole or in part at any time in
our reasonable discretion. Our failure to exercise our rights under any of the
above circumstances does not represent a waiver of these rights. Each right is
an ongoing right that may be asserted at any time. Any determination by us
concerning the conditions described above will be final and binding upon all
parties.

     If a waiver constitutes a material change to the exchange offer, we will
promptly disclose the waiver by means of a prospectus supplement that we will
distribute to the registered holders of the old notes, and we will extend the
exchange offer for a period of five to ten business days, as required by
applicable law, depending upon the significance of the waiver and the manner of
disclosure to the registered holders, if the exchange offer would otherwise
expire during the five to ten business day period.

RESALES OF NEW NOTES

     Based on interpretations by the staff of the SEC, as described in no-action
letters issued to third parties that are not related to us, we believe that new
notes issued in the exchange offer in exchange for old notes may

                                        38


be offered for resale, resold or otherwise transferred by holders of the new
notes without compliance with the registration and prospectus delivery
provisions of the Securities Act, if:

     - the new notes are acquired in the ordinary course of the holder's
       business;

     - the holders have no arrangement or understanding with any person to
       participate in the distribution of the new notes;

     - the holders are not "affiliates" of ours within the meaning of Rule 405
       under the Securities Act; and

     - the holders are not a broker-dealer who purchased old notes directly from
       us for resale pursuant to Rule 144A or any other available exemption
       under the Securities Act.

     However, the SEC has not considered the exchange offer described in this
prospectus in the context of a no-action letter. The staff of the SEC may not
make a similar determination with respect to the exchange offer as in the other
circumstances. Each holder who wishes to exchange old notes for new notes will
be required to represent that it meets the above three requirements.

     Any holder who is an affiliate of ours or who intends to participate in the
exchange offer for the purpose of distributing new notes or any broker-dealer
who purchased old notes directly from us for resale pursuant to Rule 144A or any
other available exemption under the Securities Act:

     - cannot rely on the applicable interpretations of the staff of the SEC
       mentioned above;

     - will not be permitted or entitled to tender the old notes in the exchange
       offer; and

     - must comply with the registration and prospectus delivery requirements of
       the Securities Act in connection with any resale transaction.

     Each broker-dealer that receives new notes for its own account in exchange
for old notes must acknowledge that the old notes were acquired by it as a
result of market-making activities or other trading activities and agree that it
will deliver a prospectus that meets the requirements of the Securities Act in
connection with any resale of the new 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. Please read "Plan of Distribution." A broker-dealer may use this
prospectus, as it may be amended or supplemented from time to time, in
connection with the resales of new notes received in exchange for old notes that
the broker-dealer acquired as a result of market-making or other trading
activities. Any holder that is a broker-dealer participating in the exchange
offer must notify the exchange agent at the telephone number set forth in the
enclosed letter of transmittal and must comply with the procedures for
broker-dealers participating in the exchange offer. We have not entered into any
arrangement or understanding with any person to distribute the new notes to be
received in the exchange offer.

     In addition, to comply with state securities laws, the new notes may not be
offered or sold in any state unless they have been registered or qualified for
sale in such state or an exemption from registration or qualification, with
which there has been compliance, is available. The offer and sale of the new
notes to "qualified institutional buyers," as defined under Rule 144A of the
Securities Act, is generally exempt from registration or qualification under the
state securities laws. We currently do not intend to register or qualify the
sale of new notes in any state where an exemption from registration or
qualification is required and not available.

     DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET FORTH
ABOVE OR TRANSMISSION OF SUCH LETTER OF TRANSMITTAL VIA FACSIMILE OTHER THAN AS
SET FORTH ABOVE DOES NOT CONSTITUTE A VALID DELIVERY OF THE LETTER OF
TRANSMITTAL.

FEES AND EXPENSES

     The expenses of soliciting tenders pursuant to this exchange offer will be
paid by us. We have agreed to pay the exchange agent reasonable and customary
fees for its services and will reimburse it for its reasonable out-of-pocket
expenses in connection with the exchange offer. We will also pay brokerage
houses and other custodians, nominees and fiduciaries the reasonable
out-of-pocket expenses incurred by them in forwarding copies of this prospectus
and related documents to the beneficial owners of old notes, and in handling or
tendering for their customers. We will not make any payment to brokers, dealers
or others soliciting acceptances of the exchange offer.

     Holders who tender their old notes for exchange will not be obligated to
pay any transfer taxes on the exchange. If, however, new notes are to be
delivered to, or are to be issued in the name of, any person other than the
registered holder of the old notes tendered, or if a transfer tax is imposed for
any reason other than the exchange of old notes in connection with the exchange
offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the letter of transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.

TRANSFER TAXES

     We will pay all transfer taxes, if any, applicable to the exchange of old
notes under the exchange offer. The tendering holder, however, will be required
to pay any transfer taxes, whether imposed on the registered holder or any other
person, if a transfer tax is imposed for any reason other than the exchange of
old notes under the exchange offer.

CONSEQUENCES OF FAILURE OF EXCHANGE OUTSTANDING SECURITIES

     Holders who desire to tender their old notes in exchange for new notes
registered under the Securities Act should allow sufficient time to ensure
timely delivery. Neither the exchange agent nor us is under any duty to give
notification of defects or irregularities with respect to the tenders of old
notes for exchange.

     Old notes that are not tendered or are tendered but not accepted will,
following the completion of the exchange offer, continue to be subject to the
provisions in the indenture regarding the transfer and exchange of the old notes
and the existing restrictions on transfer set forth in the legend on the old
notes set forth in the indenture for the notes. Except in limited circumstances
with respect to specific types of holders of old notes, we will have no further
obligation to provide for the registration under the Securities Act of such old
notes. In general, old notes, unless registered under the Securities Act, may
not be offered or sold except pursuant to an exemption from, or in a transaction
not subject to, the Securities Act and applicable state securities laws.

                                        40


     We do not currently anticipate that we will take any action to register the
old notes under the Securities Act or under any state securities laws. Upon
completion of the exchange offer, holders of the old notes will not be entitled
to any further registration rights under the registration rights agreement,
except under limited circumstances.

     Holders of the new notes issued in the exchange offer, any old notes which
remain outstanding after completion of the exchange offer and the previously
issued notes will vote together as a single class for purposes of determining
whether holders of the requisite percentage of the class have taken certain
actions or exercised certain rights under the indenture.

ACCOUNTING TREATMENT

     We will record the new notes at the same carrying value as the old notes,
as reflected in our accounting records on the date of the exchange. Accordingly,
we will not recognize any gain or loss for accounting purposes. The expenses of
the exchange offer will be amortized over the term of the new notes.

OTHER

     Participation in the exchange offer is voluntary, and you should consider
carefully whether to accept. You are urged to consult your financial and tax
advisors in making your own decision on what action to take.

                                        41


                          DESCRIPTION OF THE NEW NOTES

     We issued the old notes under a first supplemental indenture, dated as of
April 8, 2005, to the indenture (as supplemented, the "Indenture"), dated as of
April 1, 2004, among us, the subsidiary guarantors and U.S. Bank National
Association, as trustee (the "Trustee"), under which $175.0 million of 7 1/8%
Senior Notes due 2012 were previously issued. We will issue the new notes under
the same indenture under which we issued the old notes, and the new notes will
represent the same debt as the old notes for which they are exchanged.

     The indenture is governed by the Trust Indenture Act of 1939 (the "Trust
Indenture Act"). The terms of the notes include those stated in the indenture
and those made part of the indenture by reference to the Trust Indenture Act.
The registration rights agreement referred to under the caption "-- Registration
Rights" sets forth the rights holders of the old notes have to require us to
register their notes with the SEC.

     On April 1, 2004, we issued $175.0 million in aggregate principal amount of
7 1/8% Senior Notes due 2012. The $100.0 million principal amount of old notes
are, and the new notes will be, Additional Notes (as described below) under the
Indenture, and will be treated together with the previously issued notes as a
single class of debt securities under the Indenture.

     Old notes that remain outstanding after the completion of the exchange
offer, together with the new notes and the previously issued notes, will be
treated as a single class of securities under the Indenture. Otherwise
unqualified references herein to "notes" shall, unless the context requires
otherwise, include the previously issued notes, the old notes and the new notes,
and all references to specified percentages in aggregate principal amount of the
notes shall be deemed to mean, at any time after the exchange offer is
completed, such percentage in aggregate principal amount of the previously
issued notes, the old notes and the new notes then outstanding.

     The terms of the new notes will be substantially identical to the terms of
the old notes, except that the new notes:

     - will have been registered under the Securities Act;

     - will not be subject to transfer restrictions applicable to the old notes;
       and

     - will not have the benefit of the registration rights agreement applicable
       to the old notes.

     The following description is a summary of the material provisions of the
Indenture and the registration rights agreement. It does not restate those
agreements in their entirety. We urge you to read the Indenture and the
registration rights agreement because they, and not this description, define
your rights as Holders of these notes. You may request copies of the Indenture
and the registration rights agreement at the address set forth under the heading
"-- Additional Information."

     You can find the definitions of certain capitalized terms used in this
description that are not otherwise defined in this description under the
subheadings "-- Certain Definitions," and "-- Registration Rights." In this
description, the word "Company" refers only to KCS Energy, Inc. and not to any
of its subsidiaries.

BRIEF DESCRIPTION OF THE NOTES

  THE NOTES

     These notes:

     - will be general unsecured senior obligations of the Company;

     - will be issued in an aggregate principal amount of $100.0 million, and
       will form a single class of debt securities with the $175.0 million
       principal amount of notes previously issued and outstanding, subject to
       the Company's ability to again issue Additional Notes under certain
       circumstances;

     - will be equal in right of payment to all existing and future senior
       Indebtedness of the Company;

     - will be effectively subordinate in right of payment to any secured
       Indebtedness of the Company to the extent of the collateral, including
       Indebtedness under the Company's existing bank credit facility;
                                        42


     - will be senior in right of payment to any future subordinated
       Indebtedness of the Company;

     - will be unconditionally guaranteed by the Guarantors; and

     - will be eligible for trading on The PORTAL(SM) Market.

  THE SUBSIDIARY GUARANTEES

     These notes will be jointly and severally guaranteed by each of the
Company's present Restricted Subsidiaries and its future domestic Restricted
Subsidiaries.

     The Subsidiary Guarantees of these notes:

     - will be general unsecured senior obligations of each Guarantor;

     - will be equal in right of payment to all existing and future senior
       Indebtedness of each Guarantor;

     - will be effectively subordinate in right of payment to any secured
       Indebtedness of each Guarantor to the extent of the collateral, including
       Indebtedness of the Guarantors under the Company's bank credit facility;
       and

     - will be senior in right of payment to any future subordinated
       Indebtedness of each Guarantor.

     After giving effect to the issuance of the old notes, the consummation of
the Company's acquisition of oil and gas properties and related assets located
primarily in its North Louisiana -- East Texas core operating area and the
application of the net proceeds from the issuance of the old notes as intended,
as of March 31, 2005, the Company and the Guarantors would have had no
Indebtedness outstanding other than the notes. However, the Company has a $250.0
million bank credit facility, whose borrowing base is $165.0 million after the
issuance of the old notes, which, if drawn, would be secured Indebtedness. As of
June 30, 2005, $15.0 million was outstanding under our bank credit facility.

     As of the date of the Indenture, all of the Company's subsidiaries will be
"Restricted Subsidiaries." However, under the circumstances described below
under the subheading "-- Certain Definitions -- Unrestricted Subsidiary," the
Company will be permitted to designate certain of its subsidiaries as
"Unrestricted Subsidiaries." Unrestricted Subsidiaries will not be subject to
many of the restrictive covenants in the Indenture. Unrestricted Subsidiaries
will not guarantee these notes.

PRINCIPAL, MATURITY AND INTEREST

     The Company issued the old notes with a maximum aggregate principal amount
of $100.0 million. The old notes are, and the new notes will be, additional
notes (the "Additional Notes") to the $175.0 million of notes (the "Initial
Notes") previously issued and outstanding under the Indenture. The Company again
may issue Additional Notes from time to time after this offering in an unlimited
amount, subject to the provisions of the Indenture described below under the
caption "-- Certain Covenants -- Incurrence of Indebtedness," provided, however,
in no event may the Company issue any Additional Notes if, as a result of any
such issuance, the aggregate principal amount of notes outstanding would exceed
the maximum aggregate principal amount of notes permitted under the Existing
Credit Facilities or any other Credit Facilities, in each case as in effect on
the date of such issuance. The Initial Notes, these Additional Notes and any
other Additional Notes subsequently issued under the Indenture will be treated
as a single class for all purposes under the Indenture, including, without
limitation, waivers, amendments, redemptions and offers to purchase. Unless
otherwise provided or the context otherwise requires, for all purposes of the
Indenture and this "Description of the New Notes," references to the notes
include the Initial Notes, these Additional Notes and any further Additional
Notes actually issued.

     The Company will issue notes in denominations of $1,000 and integral
multiples of $1,000. The notes will mature on April 1, 2012.

                                        43


     Interest on the new notes will accrue at the rate of 7 1/8% per year and
will be payable semiannually in arrears on April 1 and October 1, commencing on
October 1, 2005. The Company will make each interest payment to the Holders of
record of the notes on the immediately preceding March 15 and September 15.

     Interest on the new notes will accrue from April 1, 2005, the date it was
most recently paid on the Initial Notes. Interest will be computed on the basis
of a 360-day year comprised of twelve 30-day months.

     The interest rate on the old notes is subject to increase if the Company
does not file a registration statement relating to the Registered Exchange Offer
on a timely basis, if the registration statement is not declared effective on a
timely basis or if certain other conditions are not satisfied, all as further
described under the caption "-- Registration Rights." All references to interest
on the notes shall include any such additional interest that may be payable.

METHODS OF RECEIVING PAYMENTS ON THE NOTES

     If a Holder of not less than $5.0 million aggregate principal amount of any
notes has given wire transfer instructions to the Company, the Company will make
all principal, premium and interest payments on those notes in accordance with
those instructions. All other payments on these notes will be made at the office
or agency where notes may be presented for payment (the "Paying Agent") within
the City and State of New York unless the Company elects to make interest
payments by check mailed to the Holders at their addresses set forth in the
register of Holders.

     The Company will make all principal, premium and interest payments on each
note in global form registered in the name of The Depository Trust Company
("DTC") or its nominee in immediately available funds to DTC or its nominee, as
the case may be, as the Holder of such global note.

PAYING AGENT AND REGISTRAR FOR THE NOTES

     The Bank of New York Trust Company, N.A. will initially act as Paying Agent
and registrar. The Company may change the Paying Agent or registrar without
prior notice to the Holders of the notes, and the Company or any of its
Subsidiaries may act as Paying Agent or registrar.

TRANSFER AND EXCHANGE

     A Holder may transfer or exchange notes in accordance with the Indenture.
The registrar and the Trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Company is not required to transfer or exchange any note selected
for redemption. Also, the Company is not required to transfer or exchange any
note for a period of 15 days before a selection of notes to be redeemed.

     The Holder of a note will be treated as the owner of it for all purposes.

SUBSIDIARY GUARANTEES

     The Guarantors will jointly and severally guarantee the Company's
obligations under these notes on a senior unsecured basis. The obligations of
each Guarantor under its Subsidiary Guarantee will be limited in a manner
intended to prevent that Subsidiary Guarantee from constituting a fraudulent
conveyance under applicable laws, although no assurance can be given that a
court would give the Holders the benefit of such a provision. Please read "Risk
Factors -- Risks Related to Our Indebtedness and the Notes -- A subsidiary
guarantee could be voided if it constitutes a fraudulent transfer under U.S.
bankruptcy or similar state law, which would prevent the holders of the notes
from relying on that subsidiary to satisfy claims."

                                        44


     The Company shall not permit a Guarantor to sell or otherwise dispose of
all or substantially all of its assets, or consolidate with or merge with or
into (whether or not such Guarantor is the surviving Person), another Person
(other than the Company or another Guarantor) unless:

          (1) immediately after giving effect to that transaction, no Default or
     Event of Default (as described below under "-- Events of Default and
     Remedies") shall have occurred and be continuing; and

          (2) either:

             (a) the Person acquiring the property in any such sale or
        disposition or the Person formed by or surviving any such consolidation
        or merger assumes all the obligations of that Guarantor under its
        Subsidiary Guarantee pursuant to a supplemental indenture satisfactory
        to the Trustee; or

             (b) an amount equal to the Net Proceeds of such sale or other
        disposition is applied in accordance with the provisions of the
        Indenture described under the caption "-- Repurchase at the Option of
        Holders -- Asset Sales."

     The Subsidiary Guarantee of a Guarantor will be released in accordance with
the applicable provisions of the Indenture:

          (1) in connection with any sale or other disposition of all or
     substantially all of the assets of that Guarantor (including by way of
     merger or consolidation), other than to the Company or another Guarantor,
     if the Company applies the Net Proceeds of that sale or other disposition
     in accordance with the provisions of the Indenture described under the
     caption "-- Repurchase at the Option of Holders -- Asset Sales;"

          (2) in connection with any sale or other disposition of all of the
     Capital Stock of a Guarantor (including by way of merger or consolidation)
     other than to the Company or another Guarantor, if the Company applies the
     Net Proceeds of that sale or other disposition in accordance with the
     provisions of the Indenture described under the caption "-- Repurchase at
     the Option of Holders -- Asset Sales;" or

          (3) if the Company designates any Restricted Subsidiary that is a
     Guarantor as an Unrestricted Subsidiary in accordance with the provisions
     of the Indenture.

     Please read "-- Repurchase at the Option of Holders -- Asset Sales."

OPTIONAL REDEMPTION

     On or prior to April 1, 2007, the Company may on any one or more occasions
redeem up to 35% of the aggregate principal amount of notes (including any
Additional Notes) originally issued prior to the redemption date under the
Indenture at a redemption price of 107.125% of the principal amount thereof,
plus accrued and unpaid interest to the redemption date, with the net cash
proceeds of one or more Equity Offerings; provided that

          (1) at least 65% in aggregate principal amount of notes (including any
     Additional Notes) originally issued under the Indenture remain outstanding
     immediately after the occurrence of such redemption (excluding notes held
     by the Company and its Subsidiaries); and

          (2) each such redemption must occur within 90 days of the date of the
     closing of the related Equity Offering.

     Except pursuant to the preceding paragraph, the notes will not be
redeemable at the Company's option prior to April 1, 2008.

     On or after April 1, 2008, the Company may redeem all or a part of the
notes at any time or from time to time upon not less than 30 nor more than 60
days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest thereon, if any, to the
applicable

                                        45

</Table>

SELECTION AND NOTICE

     If less than all of the notes are to be redeemed at any time, the Trustee
will select notes for redemption as follows:

          (1) if the notes are listed, in compliance with the requirements of
     the principal national securities exchange on which the notes are listed;
     or

          (2) if the notes are not so listed, on a pro rata basis.

     Notes or portions of notes the Trustee selects for redemption shall be in
amounts of $1,000 or a whole multiple of $1,000. Notices of redemption shall 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. Notices of redemption may not be conditional.

     If any note is to be redeemed in part only, the notice of redemption that
relates to that note shall state the portion of the principal amount thereof to
be redeemed. A new note in principal amount equal to the unredeemed portion of
the outstanding note will be issued in the name of the Holder thereof upon
cancellation of the outstanding 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

     The Company is not required to make any mandatory redemption or sinking
fund payments with respect to the notes. However, under certain circumstances,
the Company may be required to offer to purchase notes as described under the
captions "-- Repurchase at the Option of Holders -- Change of Control" and
"-- Asset Sales." The Company may at any time and from time to time purchase
notes in the open market or otherwise.

REPURCHASE AT THE OPTION OF HOLDERS

  CHANGE OF CONTROL

     If a Change of Control occurs, each Holder of notes will have the right to
require the Company to repurchase all or any part (equal to $1,000 or an
integral multiple thereof) of that Holder's notes pursuant to the offer
described below (the "Change of Control Offer"). In the Change of Control Offer,
the Company will offer a payment (the "Change of Control Payment") in cash equal
to 101% of the aggregate principal amount of notes to be repurchased plus
accrued and unpaid interest thereon, if any, to the date of purchase. Within 30
days following any Change of Control, the Company will mail a notice to each
Holder describing the transaction or transactions that constitute the Change of
Control and offering to repurchase notes on the date (the "Change of Control
Payment Date") specified in such notice, which date will be no earlier than 30
days nor later than 60 days from the date such notice is mailed, pursuant to the
procedures required by the Indenture and described in such notice. The Company
will comply with the requirements of Rule 14e-l under the Exchange Act and any
other securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the 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 herein, 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 the Company's compliance with such securities laws or
regulations.

                                        46


     On the Change of Control Payment Date, the Company will, to the extent
lawful:

          (1) accept for payment all notes or portions thereof properly tendered
     pursuant to the Change of Control Offer;

          (2) deposit with the Paying Agent an amount equal to the Change of
     Control Payment in respect of all notes or portions thereof so tendered;
     and

          (3) deliver or cause to be delivered to the Trustee the notes so
     accepted together with an Officers' Certificate stating the aggregate
     principal amount of notes or portions thereof being purchased by the
     Company.

     The Paying Agent will promptly mail to each Holder of notes so tendered and
not withdrawn the Change of Control Payment for such tendered notes, and the
Trustee will promptly authenticate and mail (or cause to be transferred by book
entry) to each Holder a new note equal in principal amount to any unpurchased
portion of the notes surrendered, if any, by such Holder; provided that each
such new note will be in a principal amount of $1,000 or an integral multiple
thereof.

     If the Change of Control Payment Date is on or after an interest payment
record date and on or before the related interest payment date, any accrued and
unpaid interest will be paid to the Person in whose name a note is registered at
the close of business on such record date, and no other interest will be payable
to Holders who tender pursuant to the Change of Control Offer.

     The Company will publicly announce the results of the Change of Control
Offer on or as soon as practicable after the Change of Control Payment Date.

     The provisions described above that require the Company to make a Change of
Control Offer following a Change of Control will be applicable regardless of
whether or not any other provisions of the Indenture are applicable. Except as
described above with respect to a Change of Control, the Indenture will not
contain provisions that permit the Holders of the notes to require that the
Company repurchase or redeem the notes in the event of a takeover,
recapitalization or similar transaction.

     The Company's existing bank credit facility, as amended, currently includes
a covenant prohibiting certain change of control events with respect to the
Company. Any future credit agreements or other agreements to which the Company
becomes a party may contain similar restrictions and provisions or require the
repurchase of the Indebtedness thereunder upon a Change of Control. The
occurrence of a Change of Control would result in a default under the bank
credit facility and may cause a default under other Indebtedness of the Company
and its Subsidiaries, and give the lenders thereunder the right to require the
Company to repay obligations outstanding thereunder. Moreover, the exercise by
Holders of their right to require the Company 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 the Company. The
Company's ability to repurchase notes following a Change of Control also may be
limited by the Company's then existing resources.

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

  ASSET SALES

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

          (1) the Company (or the Restricted Subsidiary, as the case may be)
     receives consideration at the time of such Asset Sale at least equal to the
     Fair Market Value of the Equity Interests or other assets issued or sold or
     otherwise disposed of; and

                                        47


          (2) at least 75% of the consideration therefor received by the Company
     or such Restricted Subsidiary is in the form of cash or Cash Equivalents.
     For purposes of this provision, each of the following shall be deemed to be
     cash:

             (a) any liabilities (as shown on the Company's or such Restricted
        Subsidiary's most recent balance sheet) of the Company or any Restricted
        Subsidiary (other than contingent liabilities and liabilities that are
        by their terms subordinated to the notes or any Subsidiary Guarantee)
        that are assumed by the transferee of any such assets pursuant to a
        customary novation agreement or similar agreement that releases the
        Company or such Restricted Subsidiary from further liability; and

             (b) any securities, notes or other obligations received by the
        Company or any such Restricted Subsidiary from such transferee that are
        converted within 120 days by the Company or such Restricted Subsidiary
        into cash (to the extent of the cash received in that conversion).

     Within the later of (x) one year after the date of receipt of any Net
Proceeds from an Asset Sale and (y) six months after the date of an agreement
entered into within such one-year period committing the Company to make an
acquisition or expenditure referred to in clauses (2) or (3) below, the Company
may apply such Net Proceeds at its option, in any one or more of the following
manners:

          (1) to permanently repay, prepay, redeem or repurchase the Senior Debt
     of the Company or any Guarantor, and cause any related loan commitment to
     be permanently reduced in an amount equal to the principal amount so
     repaid, prepaid, redeemed or repurchased;

          (2) to acquire all or substantially all of the assets of, or a
     majority of the Voting Stock of, a Company principally engaged in the Oil
     and Gas Business or to acquire additional Capital Stock in any Person that
     at such time is a Restricted Subsidiary; or

          (3) to make capital expenditures or to acquire properties or assets,
     in each case that are used or useful in the Oil and Gas Business.

     Pending the final application of any such Net Proceeds, the Company may
temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner not prohibited by the Indenture.

     Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will make
an offer (the "Asset Sale Offer") to all Holders of notes and, to the extent
required by the terms thereof, all holders of other Indebtedness that is pari
passu with the notes containing provisions similar to those set forth in the
Indenture with respect to offers to purchase or redeem with the proceeds of
sales of assets to purchase the maximum principal amount of notes and such other
pari passu Indebtedness that may be purchased out of the Excess Proceeds. The
offer price in any Asset Sale Offer will be equal to 100% of principal amount
(or accreted value in the case of any such other pari passu Indebtedness issued
with a significant original issue discount) plus accrued and unpaid interest, if
any, to the date of purchase, and will be payable in cash. If any Excess
Proceeds remain after consummation of an Asset Sale Offer, the Company may use
such Excess Proceeds for any purpose not otherwise prohibited by the Indenture.
If the aggregate principal amount of notes and such other pari passu
Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee shall select the notes and such other pari passu
Indebtedness to be purchased on a pro rata basis, on the basis of the aggregate
principal amounts (or accreted values) tendered in round denominations (which in
the case of the notes will be denominations of $1,000 principal amount or
multiples thereof). Upon completion of each Asset Sale Offer, the amount of
Excess Proceeds shall be reset at zero.

     If the Asset Sale Offer purchase date is on or after an interest payment
record date and on or before the related interest payment date, any accrued and
unpaid interest will be paid to the Person in whose name a note is registered at
the close of business on such record date, and no other interest will be payable
to holders who tender notes pursuant to the Asset Sale Offer.

     The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection
                                        48


with an Asset Sale Offer. To the extent that the provisions of any securities
laws or regulations conflict with the provisions of the covenant described
herein, 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 the Company's compliance with such securities laws or
regulations.

CERTAIN COVENANTS

  RESTRICTED PAYMENTS

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly:

          (1) declare or pay any dividend or make any other payment or
     distribution on account of the Company's or any of its Restricted
     Subsidiaries' Equity Interests (including, without limitation, any payment
     in connection with any merger or consolidation involving the Company or any
     of its Restricted Subsidiaries) or to the direct or indirect holders of the
     Company's or any of its Restricted Subsidiaries' Equity Interests in their
     capacity as such (other than dividends or distributions payable in Equity
     Interests (other than Disqualified Stock) of the Company or to the Company
     or a Restricted Subsidiary of the Company);

          (2) purchase, redeem or otherwise acquire or retire for value
     (including, without limitation, in connection with any merger or
     consolidation involving the Company) any Equity Interests of the Company
     (other than any such Equity Interests owned by the Company or any
     Restricted Subsidiary of the Company);

          (3) make any payment on or with respect to, or purchase, redeem,
     defease or otherwise acquire or retire for value, prior to scheduled
     maturity or scheduled sinking fund payment, any Subordinated Indebtedness
     of the Company or any of its Restricted Subsidiaries, except a payment of
     interest or principal at the Stated Maturity thereof; or

          (4) make any Investment other than a Permitted Investment (all such
     payments and other actions set forth in clauses (1) through (3) above and
     this clause (4) being collectively referred to as "Restricted Payments"),

     unless, at the time of and after giving effect to such Restricted Payment:

          (1) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof;

          (2) the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Fixed Charge Coverage Ratio test set forth in the first paragraph of
     the covenant described below under the caption "-- Incurrence of
     Indebtedness;" and

          (3) such Restricted Payment, together with the aggregate amount of all
     other Restricted Payments made by the Company and its Restricted
     Subsidiaries after the Issue Date (excluding Restricted Payments permitted
     by clauses (2), (3), (4), (6), (7) and (9) of the next succeeding
     paragraph, but including Restricted Payments permitted by clauses (1), (5)
     and (8) of such paragraph), is less than the sum, without duplication, of

             (a) 50% of the Consolidated Net Income of the Company for the
        period (taken as one accounting period) from the beginning of the full
        fiscal quarter during which the Issue Date falls to the end of the
        Company's most recently ended fiscal quarter for which internal
        financial statements are available at the time of such Restricted
        Payment (or, if such Consolidated Net Income for such period is a
        deficit, less 100% of such deficit); plus

             (b) 100% of the aggregate Net Cash Proceeds and 100% of the Fair
        Market Value of securities or other property other than cash (including
        Capital Stock of Persons engaged in the Oil and Gas Business that become
        Restricted Subsidiaries or assets used in the Oil and Gas Business)
        received
                                        49


        by the Company since the Issue Date from the issue or sale of Equity
        Interests of the Company (other than Disqualified Stock), other than
        Equity Interests (or Disqualified Stock or debt securities) sold 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; plus

             (c) the aggregate Net Cash Proceeds received by the Company
        subsequent to the Issue Date from the issue or sale of any Capital Stock
        of the Company (other than Disqualified Stock) to an Employee Stock
        Purchase Program; provided, however, that if an Employee Stock Purchase
        Program incurs any Indebtedness to finance the purchase of such Capital
        Stock, such aggregate amount will be limited to the excess of such Net
        Cash Proceeds over the amount of such Indebtedness plus an amount equal
        to any increase in the Consolidated Net Worth of the Company resulting
        from principal repayments made by an Employee Stock Purchase Program
        with respect to such Indebtedness; plus

             (d) the amount by which Indebtedness is reduced on the Company's
        consolidated balance sheet upon the conversion or exchange (other than
        by a Subsidiary of the Company) subsequent to the Issue Date of any
        Indebtedness convertible or exchangeable for Capital Stock (other than
        Disqualified Stock) of the Company (plus the amount of any accrued
        interest then outstanding on such Indebtedness to the extent the
        obligation to pay such interest is extinguished less the amount of any
        cash, or the fair market value of any property (as determined in good
        faith by an officer of the Company), distributed by the Company upon
        such conversion or exchange); provided, however, that the foregoing
        amount shall not exceed the Net Cash Proceeds received by the Company or
        any Restricted Subsidiary from the sale of such Indebtedness (excluding
        Net Cash Proceeds from sales to a Subsidiary of the Company or 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); plus

             (e) an amount equal to the sum of (i) 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 (ii) 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) $10.0 million.

     The preceding provisions will not prohibit:

          (1) the payment of any dividend within 60 days after the date of
     declaration thereof, if at said date of declaration such payment would have
     complied with the provisions of the Indenture (and such payment shall be
     deemed to be paid on the date of payment for purposes of any calculation
     required by this covenant);

          (2) the redemption, repurchase, retirement, defeasance or other
     acquisition of any Subordinated Indebtedness of the Company or any
     Guarantor or of any Equity Interests of the Company or any Restricted
     Subsidiary in exchange for, or out of the Net Cash Proceeds of the
     substantially concurrent sale (other than to a Subsidiary of the Company)
     of, Equity Interests of the Company (other than Disqualified Stock);
     provided that the amount of any such Net Cash Proceeds that are utilized
     for any

                                        50


     such redemption, repurchase, retirement, defeasance or other acquisition
     shall be excluded from clause (3)(b) of the preceding paragraph;

          (3) the defeasance, redemption, repurchase, retirement or other
     acquisition of other Subordinated Indebtedness of the Company or any
     Guarantor with the Net Cash Proceeds from an incurrence of any Subordinated
     Indebtedness permitted to be incurred under the caption "-- Incurrence of
     Indebtedness;"

          (4) the payment of any dividend or other distribution by a Restricted
     Subsidiary of the Company to the holders of its common Equity Interests on
     a pro rata basis;

          (5) so long as no Default has occurred and is continuing, the
     repurchase, redemption or other acquisition or retirement for value of any
     Equity Interests of the Company or any Restricted Subsidiary of the Company
     held by any employees, former employees, directors or former directors of
     Company or any of its Restricted Subsidiaries (or heirs, estates or other
     permitted transferees of such employees or directors) pursuant to any
     agreements (including employment agreements), management equity
     subscription agreement or stock option agreements or plans (or amendments
     thereto), approved by the Board of Directors, under which such individuals
     purchase or sell or are granted the right to purchase or sell shares of
     Capital Stock; provided that the aggregate price paid for all such
     repurchased, redeemed, acquired or retired Equity Interests shall not
     exceed $2.0 million in any twelve-month period;

          (6) so long as no Default has occurred and is continuing, loans or
     advances to employees of the Company or employees or directors of any
     Subsidiary of the Company, in each case as permitted by Section 402 of the
     Sarbanes-Oxley Act of 2002, the proceeds of which are used to purchase
     Capital Stock of the Company, or to refinance loans or advances made
     pursuant to this clause (6), in an aggregate amount not in excess of $1.0
     million at any one time outstanding;

          (7) repurchases or other acquisitions for value of Capital Stock
     deemed to occur upon the exercise or exchange of stock options, warrants or
     other convertible securities if such Capital Stock represents a portion of
     the exercise or exchange price thereof or made in lieu of withholding taxes
     in connection with any such exercise or exchange; provided, however, that
     the aggregate amount of such repurchases, redemption or acquisitions to
     satisfy federal income tax obligations shall not exceed $2.0 million in any
     twelve-month period;

          (8) so long as no Default has occurred and is continuing, upon the
     occurrence of a Change of Control or an Asset Sale and within 60 days after
     the completion of the offer to repurchase the notes under the covenants
     described under "-- Repurchase at the Option of Holders -- Change of
     Control" or "-- Asset Sales" above (including the purchase of all notes
     tendered), any purchase, repurchase, redemption, defeasance, acquisition or
     other retirement for value of Subordinated Obligations required under the
     terms thereof as a result of such Change of Control or Asset Sale 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 that, in the notice to Holders relating to a Change of Control
     hereunder, the Company shall describe this clause (8); or

          (9) so long as no Default has occurred or is continuing, the purchase
     by the Company of fractional shares arising out of stock dividends, splits
     or business combinations.

     The amount of all Restricted Payments (other than cash) shall be the Fair
Market Value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair
Market Value of any assets or securities that are required to be valued at the
time of such Restricted Payment by this covenant shall be evidenced by an
Officers' Certificate to be delivered to the Trustee. Not later than five
Business Days following the date of the making of any Restricted Payment, the
Company shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted, together with a copy of any related resolution
of the Board of Directors.

     For purposes of determining compliance with this covenant, if a Restricted
Payment meets the criteria of more than one of the types of Restricted Payments
described in clauses (1)-(9) above, the Company, in its

                                        51


sole discretion, may order and classify such Restricted Payment in any manner in
compliance with this covenant.

     In computing Consolidated Net Income under clause (3)(a) above, (1) the
Company shall use audited financial statements for the portions of the relevant
period for which audited financial statements are available on the date of
determination and unaudited financial statements and other current financial
data based on the books and records of the Company for the remaining portion of
such period and (2) the Company shall be permitted to rely in good faith on the
financial statements and other financial data derived from the books and records
of the Company that are available on the date of determination.

  INCURRENCE OF INDEBTEDNESS

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt); provided, however, that the Company and any Guarantor may incur
Indebtedness (including Acquired Debt), if the Fixed Charge Coverage Ratio for
the Company's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred would have been at least 2.5 to 1,
determined on a pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been incurred at the
beginning of such four-quarter period.

     The first paragraph of this covenant will not prohibit the incurrence of
any of the following items of Indebtedness (collectively, "Permitted
Indebtedness"):

          (1) the incurrence by the Company and any Guarantor of the
     Indebtedness under Credit Facilities; provided that the aggregate principal
     amount of all Indebtedness of the Company and the Guarantors outstanding at
     any time under this clause (1) under all Credit Facilities after giving
     effect to such incurrence does not exceed an amount equal to the greater of
     (a) $100.0 million less the aggregate amount of all permanent principal
     repayments since the Issue Date under a Credit Facility that are made under
     clause (1) of the second paragraph of the covenant described under
     "-- Repurchase at the Option of Holders -- Asset Sales" and (b) 20% of
     ACNTA as of the date of such incurrence;

          (2) the incurrence by the Company and its Restricted Subsidiaries of
     Existing Indebtedness (other than Indebtedness described under clause (1),
     (3) or (6) of this paragraph);

          (3) the incurrence by the Company and the Guarantors of Indebtedness
     represented by (a) the Initial Notes and the Subsidiary Guarantees, and (b)
     any notes issued pursuant to the registration rights agreement in exchange
     for the notes, and any Subsidiary Guarantees related thereto;

          (4) the incurrence by the Company or any of its Restricted
     Subsidiaries of Non-Recourse Purchase Money Indebtedness;

          (5) the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to refund, refinance or replace,
     Indebtedness (other than intercompany Indebtedness) that was permitted by
     the Indenture to be incurred under the first paragraph of this covenant or
     clause (2), (3), (4) or this clause (5) of this paragraph;

          (6) the incurrence by the Company or any of its Restricted
     Subsidiaries of intercompany Indebtedness between or among the Company and
     any of its Restricted Subsidiaries; provided, however, that:

             (a) (i) if the Company is the obligor on such Indebtedness, such
        Indebtedness must be expressly subordinated to the prior payment in full
        in cash of all obligations with respect to the notes, and (ii) if a
        Guarantor is the obligor of such Indebtedness, such Indebtedness must be
        expressly subordinated to the prior payment in full in cash of all
        obligations of such Guarantor with respect to its Subsidiary Guarantee;
        and
                                        52


             (b) (i) any subsequent issuance or transfer of Equity Interests
        that results in any such Indebtedness being held by a Person other than
        the Company or a Restricted Subsidiary thereof and (ii) any sale or
        other transfer of any such Indebtedness to a Person that is not either
        the Company or a Restricted Subsidiary thereof, shall be deemed, in each
        case, to constitute an incurrence of such Indebtedness by the Company or
        such Restricted Subsidiary, as the case may be, that was not permitted
        by this clause;

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

          (8) the accrual of interest, accretion or amortization of original
     issue discount, the payment of interest on any Indebtedness in the form of
     additional Indebtedness with the same terms, and the payment of dividends
     on Disqualified Stock, in the form of additional shares of the same class
     of Disqualified Stock;

          (9) any obligations in respect of completion bonds, performance bonds,
     bid bonds, appeal bonds, surety bonds, bankers acceptances, letters of
     credit, insurance obligations or bonds and other similar bonds and
     obligations incurred by the Company or any Restricted Subsidiary in the
     ordinary course of business and any guaranties or letters of credit
     functioning as or supporting any of the foregoing bonds or obligations;

          (10) any obligation under Interest Rate Agreements, Currency
     Agreements and Commodity Agreements; provided, that such Interest Rate
     Agreements, Currency Agreements and Commodity Agreements are related to
     business transactions of the Company or its Restricted Subsidiaries and are
     entered into for bona fide hedging purposes of the Company or its
     Restricted Subsidiaries (as determined in good faith by the Board of
     Directors or senior management of the Company);

          (11) any obligation arising from agreements of the Company or a
     Restricted Subsidiary providing for indemnification, guarantee, adjustment
     of purchase price, holdback, contingency payment obligation based on the
     performance of the acquired or disposed asset or similar obligations, in
     each case, incurred or assumed in connection with the acquisition or
     disposition of any business, asset or Capital Stock of a Restricted
     Subsidiary;

          (12) any obligation 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 five Business Days of
     incurrence; and

          (13) the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness in addition to Indebtedness permitted by
     clauses (1) through (12) above or the first paragraph above in an aggregate
     principal amount (or accrued value, as applicable) at any time outstanding
     not to exceed $25.0 million.

     For purposes of determining compliance with this "Indebtedness" covenant:

          (1) in the event that an item of proposed Indebtedness meets the
     criteria of more than one of the categories of Permitted Indebtedness
     described in clauses (1) through (13) above, or is entitled to be incurred
     pursuant to the first paragraph of this covenant, the Company will be
     permitted to classify such item of Indebtedness (or any portion thereof) on
     the date of its incurrence in any manner that complies with this covenant,
     and only be required to include the amount and type of such Indebtedness in
     one of such clauses;

          (2) all Indebtedness outstanding on the date of the Indenture under
     the Credit Facilities shall be deemed initially incurred on the Issue Date
     under clause (1) of the second paragraph of this covenant and not the first
     paragraph or clause (2) of the second paragraph of this covenant;

          (3) Guarantees of, or obligations in respect of letters of credit
     relating to, Indebtedness which is otherwise included in the determination
     of a particular amount of Indebtedness shall not be included;

                                        53


          (4) if obligations in respect of letters of credit are incurred
     pursuant to the Credit Facility and are being treated as incurred pursuant
     to clause (1) of the second paragraph above and the letters of credit
     relate to other Indebtedness, then such other Indebtedness shall not be
     included;

          (5) Indebtedness permitted by this covenant need not be permitted
     solely by reference to one provision permitting such Indebtedness but may
     be permitted in part by one such provision and in part by one or more other
     provisions of this covenant permitting such Indebtedness;

          (6) the amount of Indebtedness issued at a price that is less than the
     principal amount thereof will be equal to the amount of the liability in
     respect thereof determined in accordance with GAAP; and

          (7) Indebtedness of any Person existing at the time such Person
     becomes a Restricted Subsidiary shall be deemed to have been incurred by
     the Company and the Restricted Subsidiary at the time such Person becomes a
     Restricted Subsidiary.

     For purposes of determining compliance with any U.S. dollar-denominated
restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent
principal amount of Indebtedness denominated in a foreign currency shall be
calculated based on the relevant currency exchange rate in effect on the date
such Indebtedness was incurred, in the case of term Indebtedness, or first
committed, in the case of revolving credit Indebtedness; provided that if such
Indebtedness is incurred to refinance other Indebtedness denominated in a
foreign currency, and such refinancing would cause the applicable U.S.
dollar-dominated restriction to be exceeded if calculated at the relevant
currency exchange rate in effect on the date of such refinancing, such U.S.
dollar-dominated restriction shall be deemed not to have been exceeded so long
as the principal amount of such refinancing Indebtedness does not exceed the
principal amount of such Indebtedness being refinanced. Notwithstanding any
other provision of this covenant, the maximum amount of Indebtedness that the
Company may incur pursuant to this covenant shall not be deemed to be exceeded
solely as a result of fluctuations in the exchange rate of currencies. The
principal amount of any Permitted Refinancing Indebtedness, if incurred in a
different currency from the Indebtedness being refinanced, shall be calculated
based on the currency exchange rate applicable to the currencies in which such
Permitted Refinancing Indebtedness is denominated that is in effect on the date
of such refinancing.

  LIENS

     The Company will not, and will not permit any of its Restricted
Subsidiaries to create, incur, assume or suffer to exist any Lien on any
property or asset now owned or hereafter acquired, or any income or profits
therefrom or assign or convey any right to receive income therefrom, except
Permitted Liens, to secure (a) any Indebtedness of the Company unless prior to,
or contemporaneously therewith, the notes are equally and ratably secured for so
long as such other Indebtedness is so secured, or (b) any Indebtedness of any
Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary
Guarantee of such Guarantor is equally and ratably secured for so long as such
other Indebtedness is so secured; provided, however, that if such Indebtedness
is expressly subordinated to the notes or a Subsidiary Guarantee, the Lien
securing such Indebtedness will be subordinated and junior to the Lien securing
the notes or such Subsidiary Guarantee, as the case may be, with the same
relative priority as such Indebtedness has with respect to the notes or such
Subsidiary Guarantee.

  DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to:

          (a) pay dividends or make any other distributions on its Capital Stock
     to the Company or any of the Company's Restricted Subsidiaries, or pay any
     Indebtedness owed to the Company or any of the Company's Restricted
     Subsidiaries;

          (b) make loans or advances to the Company or any of the Company's
     Restricted Subsidiaries; or

                                        54


          (c) transfer any of its properties or assets to the Company or any of
     the Company's Restricted Subsidiaries.

     However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of:

          (1) agreements existing on the Issue Date, including the Existing
     Credit Facilities as in effect on the Issue Date;

          (2) any instrument governing Indebtedness or Capital Stock of a Person
     acquired by the Company or any of its Restricted Subsidiaries as in effect
     at the time of such acquisition (except to the extent such Indebtedness was
     incurred in connection with or in contemplation of such acquisition), which
     encumbrance or restriction is not applicable to any Person, or the
     properties or assets of any Person, other than the Person, or the property
     or assets of the Person, so acquired, provided that, in the case of
     Indebtedness, such Indebtedness was permitted by the terms of the Indenture
     to be incurred;

          (3) any agreement for the sale or other disposition of Capital Stock
     or assets of a Restricted Subsidiary that restricts distributions by such
     Restricted Subsidiary pending such sale or other disposition;

          (4) any amendment, restatement, modification, supplement, extension,
     renewal, refunding, replacement or refinancing of Indebtedness referred to
     in clauses (1) or (2), provided that the encumbrances or restrictions
     contained in the agreements governing the foregoing are no more materially
     restrictive, taken as a whole, than those contained in the agreements
     governing such Indebtedness;

          (5) restrictions on cash or other deposits by parties under agreements
     entered into in the ordinary course of the Oil and Gas Business of the
     types described in the definition of Permitted Business Investments; and

          (6) with respect to clause (c) of the preceding paragraph only, any of
     the following encumbrances or restrictions:

             (a) customary non-assignment provisions in leases entered into in
        the ordinary course of business;

             (b) purchase money obligations for property acquired in the
        ordinary course of business that impose restrictions on the property so
        acquired;

             (c) Permitted Liens or Liens securing Indebtedness otherwise
        permitted to be incurred pursuant to the provisions of the covenant
        described above under the caption "-- Liens" that limit the right of the
        Company or any of its Restricted Subsidiaries to dispose of the assets
        subject to such Lien;

             (d) customary restrictions contained in asset sale agreements
        limiting the transfer of such assets pending the closing of such sale;

             (e) customary restrictions on the subletting, assignment or
        transfer of any property or asset that is subject to a lease, license,
        sub-license or similar contract, or the assignment or transfer of any
        such lease, license, sub-license or other contract; and

             (f) customary restrictions on the disposition or distribution of
        assets or property in agreements entered into the ordinary course of
        business of the Oil and Gas Business of the types described in the
        definition of Permitted Business Investments.

  MERGER, CONSOLIDATION OR SALE OF ASSETS

     The Company may not: (1) consolidate or merge with or into another Person
(whether or not the Company is the surviving corporation); or (2) sell, assign,
transfer, lease, convey or otherwise dispose of all or

                                        55


substantially all of the properties or assets of the Company and its Restricted
Subsidiaries taken as whole, in one or more related transactions, to another
Person, unless:

          (1) either:

             (a) the Company is the surviving corporation; or

             (b) the Person formed by or surviving any such consolidation or
        merger (if other than the Company) or to which such sale, assignment,
        transfer, lease, conveyance or other disposition shall have been made is
        a corporation, partnership or limited liability company organized or
        existing under the laws of the United States, any state thereof or the
        District of Columbia;

          (2) the Person formed by or surviving any such consolidation or merger
     (if other than the Company) or the Person to which such sale, assignment,
     transfer, lease, conveyance or other disposition shall have been made
     assumes all the obligations of the Company under the notes, the Indenture
     and the registration rights agreement pursuant to a supplemental indenture
     reasonably satisfactory to the Trustee;

          (3) immediately after such transaction no Default or Event of Default
     exists; and

          (4) the Company or the Person formed by or surviving any such
     consolidation or merger (if other than the Company) will, on the date of
     such transaction after giving pro forma effect thereto and any related
     financing transactions as if the same had occurred at the beginning of the
     applicable four-quarter period, be permitted to Incur at least $1.00 of
     additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test
     set forth in the first paragraph of the covenant described above under the
     caption "-- Incurrence of Indebtedness."

     For purposes of this covenant, the sale, assignment, transfer, lease,
conveyance or other disposition of all or substantially all of the properties or
assets of one or more Subsidiaries of the Company, which properties or assets,
if held by the Company instead of such Subsidiaries, would constitute all or
substantially all of the properties or assets of the Company on a consolidated
basis, shall be deemed to be the transfer of all or substantially all of the
properties or assets of the Company.

     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 "all
or substantially all" of the properties or assets of a Person.

     Clause (4) of this "Merger, Consolidation, or Sale of Assets" covenant will
not apply to a sale, assignment, transfer, conveyance or other disposition of
assets between or among the Company and any of its Restricted Subsidiaries that
are Guarantors.

  TRANSACTIONS WITH AFFILIATES

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each, an "Affiliate Transaction"), unless:

          (1) such Affiliate Transaction is on terms that are no less favorable
     to the Company or the relevant Restricted Subsidiary than those that would
     have been obtained at the time of such transaction in arm's-length dealings
     by the Company or such Restricted Subsidiary with a Person who is not an
     Affiliate; and

          (2) (a) with respect to any Affiliate Transaction or series of related
     Affiliate Transactions involving aggregate consideration in excess of $5.0
     million, a majority of the disinterested members of the Board of Directors
     have determined that the criteria set forth in clause (1) are satisfied
     with respect to such Affiliate Transaction(s) and have approved such
     Affiliate Transaction(s), as evidenced by a resolution delivered to the
     Trustee and certified by an Officers' Certificate as having been adopted by
     the Board of Directors; and

                                        56


          (b) with respect to any Affiliate Transaction or series of related
     Affiliate Transactions involving aggregate consideration in excess of $20.0
     million, the Company delivers to the Trustee a written opinion that such
     Affiliate Transaction(s) is fair, from a financial point of view, to the
     Company and its Restricted Subsidiaries, taken as a whole, or that such
     Affiliate Transaction(s) 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 is not an
     Affiliate, in either such case issued by an accounting, appraisal or
     investment banking firm of national standing that is not an Affiliate of
     the Company.

     The following items shall not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraph:

          (1) any employment agreement or other employee compensation plan or
     arrangement existing on the Issue Date or thereafter entered into by the
     Company or any of its Restricted Subsidiaries in the ordinary course of
     business and consistent with the past practice of the Company or such
     Restricted Subsidiary;

          (2) transactions between or among the Company and/or its Restricted
     Subsidiaries;

          (3) Investments (other than Permitted Investments) or Restricted
     Payments that, in each case, are permitted by the provisions of the
     Indenture described above under the caption "-- Restricted Payments;"

          (4) loans or advances to employees, officers or directors in the
     ordinary course of business of the Company or any of its Restricted
     Subsidiaries, in each case only as permitted by Section 402 of the
     Sarbanes-Oxley Act of 2002, but in any event not to exceed $1.0 million in
     the aggregate outstanding at any one time;

          (5) indemnities of officers, directors and employees of the Company or
     any Restricted Subsidiary consistent with applicable charter, bylaw or
     statutory provisions; and

          (6) the payment of reasonable and customary fees to directors of the
     Company or any of its Restricted Subsidiaries who are not employees of the
     Company or any Subsidiary.

  ADDITIONAL SUBSIDIARY GUARANTEES

     If the Company or any of its Restricted Subsidiaries acquires or creates
another Restricted Subsidiary (other than Foreign Subsidiaries) after the Issue
Date, then that newly acquired or created Restricted Subsidiary must become a
Guarantor and execute a supplemental indenture satisfactory to the Trustee and
deliver an Opinion of Counsel to the Trustee as provided in the Indenture.

  BUSINESS ACTIVITIES

     The Company will not, and will not permit any Restricted Subsidiary to,
engage in any business other than the Oil and Gas Business, except to such
extent as would not be material in the opinion of the Board of Directors (which
opinion shall be reasonable and made in good faith) to the Company and its
Restricted Subsidiaries taken as a whole.

  REPORTS

     Whether or not required by the SEC, so long as any notes are outstanding,
the Company will furnish to the Holders of notes, within the time periods
specified in the SEC's rules and regulations:

          (1) all quarterly and annual financial information that would be
     required to be contained in a filing with the SEC on Forms 10-Q and 10-K if
     the Company were required to file such Forms, including a section on
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations" and, with respect to the annual information only, a report on
     the annual financial statements by the Company's certified independent
     public accountants; and

                                        57


          (2) all current reports that would be required to be filed with the
     SEC on Form 8-K if the Company were required to file such reports.

     If the Company has designated any of its Subsidiaries as Unrestricted
Subsidiaries, then the quarterly and annual financial information required by
the preceding paragraph shall include a reasonably detailed presentation, either
on the face of the financial statements or in the footnotes thereto, and in
Management's Discussion and Analysis of Financial Condition and Results of
Operations, of the financial condition and results of operations of the Company
and its Restricted Subsidiaries separate from the financial condition and
results of operations of the Unrestricted Subsidiaries of the Company.

     In addition, whether or not required by the SEC, the Company will file a
copy of all of the information and reports referred to in clause (1) and (2)
above with the SEC for public availability within the time periods specified in
the SEC's rules and regulations (unless the SEC will not accept such a filing).

     In addition, the Company agrees that, for so long as any notes remain
outstanding, if at any time it is not required to file with the SEC the reports
required by the preceding paragraphs, it will furnish to holders of notes and to
prospective investors, upon request, the information required to be delivered
pursuant to Rule 144A(d)(4) under the Securities Act.

EVENTS OF DEFAULT AND REMEDIES

     Each of the following is an "Event of Default":

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

          (2) default in payment when due of the principal of or premium, if
     any, on the notes;

          (3) failure by the Company to comply with the provisions described
     under the caption "-- Certain Covenants -- Merger, Consolidation or Sale of
     Assets;"

          (4) failure by the Company or any of its Restricted Subsidiaries to
     comply for 30 days after receipt of written notice from the Trustee or the
     Holders of 25% in principal amount of the notes with the provisions
     described under the captions "-- Redemption at the Option of
     Holders -- Change of Control" and "-- Asset Sales" and "-- Certain
     Covenants -- Restricted Payments," "-- Incurrence of Indebtedness,"
     "-- Liens," "-- Dividend and Other Payment Restrictions Affecting
     Subsidiaries," "-- Transactions with Affiliates," "-- Additional Subsidiary
     Guarantees," "-- Business Activities" and "-- Reports;"

          (5) failure by the Company for 60 days after receipt of written notice
     from the Trustee or the Holders of 25% in principal amount of the notes to
     comply with any of its other agreements in the Indenture;

          (6) default under any mortgage, indenture or instrument under which
     there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Company or any of its Restricted
     Subsidiaries (or the payment of which is Guaranteed by the Company or any
     of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now
     exists, or is created after the date of the Indenture, if that default:

             (a) is caused by a failure to pay principal of or premium, if any,
        or interest on such Indebtedness prior to the expiration of the grace
        period provided in such Indebtedness (a "Payment Default"); or

             (b) results in the acceleration of such Indebtedness prior to its
        Stated Maturity, and, in each case, the principal amount of any such
        Indebtedness, together with the principal amount of any other such
        Indebtedness under which there has been a Payment Default or the
        maturity of which has been so accelerated, aggregates $5.0 million or
        more (the "cross-acceleration provision"); provided, however, that if
        any such Payment Default is cured or waived or any such acceleration
        rescinded, or such Indebtedness is repaid, within a period of ten days
        from the continuation of such Payment Default beyond the applicable
        grace period or the occurrence of such acceleration, as the case may
                                        58


        be, such Event of Default and any consequential acceleration of the
        notes shall be automatically rescinded, so long as such rescission does
        not conflict with any judgment or decree;

          (7) failure by the Company or any of its Restricted Subsidiaries to
     pay final judgments aggregating in excess of $5.0 million (net of any
     amounts covered by insurance), which judgments are not paid, discharged or
     stayed for a period of 60 days (the "judgment provisions");

          (8) any Subsidiary Guarantee of a Guarantor shall be held in any
     judicial proceeding to be unenforceable or invalid or, except as permitted
     by the Indenture, shall cease for any reason to be in full force and effect
     or any Guarantor, or any Person acting on behalf of any Guarantor, shall
     deny or disaffirm its obligations under its Subsidiary Guarantee (the
     "guarantee default provision"), in each case with respect to any Guarantor
     that is also a Significant Subsidiary or any group of Guarantors that,
     taken together, would constitute a Significant Subsidiary; and

          (9) certain events of bankruptcy or insolvency with respect to the
     Company or any Restricted Subsidiary that is also a Significant Subsidiary
     or any group of Restricted Subsidiaries that, taken together, would
     constitute a Significant Subsidiary (the "bankruptcy provision").

     In the case of an Event of Default arising from certain events of
bankruptcy or insolvency with respect to the Company, any Restricted Subsidiary
that is a Significant Subsidiary or any group of Restricted Subsidiaries that,
taken together, would constitute a Significant Subsidiary, all outstanding notes
will become due and payable immediately without further action or notice. If any
other Event of Default occurs and is continuing, the Trustee or the Holders of
at least 25% in principal amount of the then outstanding notes may declare all
the notes to be due and payable immediately. Under certain circumstances, the
Holders of a majority in principal amount of the then outstanding notes may
rescind an acceleration with respect to the notes and its consequences.

     Holders of the notes may not enforce the Indenture or the notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal, premium or interest) if
it determines that withholding notice is in their interest.

     The Holders of a majority in aggregate principal amount of the notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest or premium on, or the principal of, the notes or a Default or Event of
Default in respect of a provision that under "-- Amendment, Supplement and
Waiver" below cannot be amended without the consent of each Holder affected.

     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture. Upon becoming aware of any Default or
Event of Default, the Company is required to deliver to the Trustee a statement
specifying such Default or Event of Default.

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     No director, officer, employee, incorporator, member, partner or
stockholder of the Company or any Guarantor, as such, shall have any liability
for any obligations of the Company or the Guarantors under the notes, the
Indenture, the Subsidiary Guarantees, the registration rights agreement or for
any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of 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. The waiver and release may not be effective to waive liabilities
under the federal securities laws, and it is the view of the SEC that such a
waiver is against public policy.

                                        59


LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding notes and the Indenture
and all obligations of the Guarantors discharged with respect to their
Subsidiary Guarantees ("Legal Defeasance") except for:

          (1) the rights of Holders of outstanding notes to receive payments in
     respect of the principal of, premium, if any, and interest on such notes
     when such payments are due from the trust referred to below;

          (2) the Company's obligations with respect to the notes concerning
     issuing temporary notes, registration of notes, mutilated, destroyed, lost
     or stolen notes and the maintenance of an office or agency for payment and
     money for security payments held in trust;

          (3) the rights, powers, trusts, duties and immunities of the Trustee,
     and the Company's obligations in connection therewith; and

          (4) the Legal Defeasance provisions of the Indenture.

     In addition, the Company may, at its option and at any time, elect to
terminate its obligations under "-- Repurchase at the Option of
Holders -- Change of Control" and "-- Asset Sales" and under the covenants
described under "-- Certain Covenants" (other than the covenant described under
"-- Merger, Consolidation or Sale of Assets"), the operation of the
cross-acceleration provision, the judgment provision, the guarantee default
provision and (with respect only to Significant Subsidiaries) the bankruptcy
provisions described under "-- Events of Default and Remedies" above and the
limitations contained in clause (4) of the first paragraph under "-- Certain
Covenants -- Merger, Consolidation or Sale of Assets" above ("Covenant
Defeasance") and certain other covenants or obligations of the Company set forth
in the Indenture, and thereafter any omission to comply with such obligations or
provisions will not constitute a Default or Event of Default.

     The Company may exercise its Legal Defeasance option notwithstanding its
prior exercise of its Covenant Defeasance option. If the Company exercises its
Legal Defeasance option, payment of the notes may not be accelerated because of
an Event of Default with respect thereto. If the Company exercises its Covenant
Defeasance option, payment of the notes may not be accelerated because of an
Event of Default specified in clauses (4), (5), (6), (7) (8) or (with respect
only to Significant Subsidiaries) (9) under "-- Events of Default and Remedies"
above or because of the failure of the Company to comply with clause (4) of the
first paragraph under "-- Certain Covenants -- Merger, Consolidation or Sale of
Assets" above. If the Company exercises its Legal Defeasance or Covenant
Defeasance option, each Guarantor will be released from its obligations with
respect to its Subsidiary Guarantee.

     In order to exercise either Legal Defeasance or Covenant Defeasance:

          (1) the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders of the notes, cash in U.S. dollars,
     non-callable Government Securities, or a combination thereof, in such
     amounts as will be sufficient, in the opinion of a nationally recognized
     firm of independent public accountants, to pay the principal of, premium,
     if any, and interest on the outstanding notes on the Stated Maturity or on
     the applicable redemption date, as the case may be, and the Company must
     specify whether the notes are being defeased to Stated Maturity or to a
     particular redemption date;

          (2) in the case of Legal Defeasance, the Company shall have delivered
     to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee
     confirming that (a) the Company has received from, or there has been
     published by, the Internal Revenue Service a ruling or (b) since the Issue
     Date, there has been a change in the applicable federal income tax law, in
     either case to the effect that, and based thereon such Opinion of Counsel
     shall confirm that, the Holders of the outstanding notes will not recognize
     income, gain or loss for federal income tax purposes as a result of such
     Legal Defeasance 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 Legal Defeasance had not occurred;

                                        60


          (3) in the case of Covenant Defeasance, the Company shall have
     delivered to the Trustee an Opinion of Counsel reasonably acceptable to the
     Trustee confirming that the Holders of the outstanding notes will not
     recognize income, gain or loss for federal income tax purposes as a result
     of such Covenant Defeasance 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 Covenant Defeasance had not occurred;

          (4) no Default or Event of Default shall have occurred and be
     continuing either: (a) on the date of such deposit (other than a Default or
     Event of Default resulting from the borrowing of funds to be applied to
     such deposit); or (b) insofar as Events of Default from bankruptcy or
     insolvency events are concerned, at any time in the period ending on the
     91st day after the date of deposit;

          (5) such Legal Defeasance or Covenant Defeasance will not result in a
     breach or violation of, or constitute a default under any material
     agreement or instrument (other than the Indenture) to which the Company or
     any of its Restricted Subsidiaries is a party or by which the Company or
     any of its Restricted Subsidiaries is bound;

          (6) the Company must have delivered to the Trustee an Opinion of
     Counsel to the effect that after the 91st day following the deposit, the
     trust funds will not be subject to the effect of any applicable bankruptcy,
     insolvency, reorganization or similar laws affecting creditors' rights
     generally;

          (7) the Company must deliver to the Trustee an Officers' Certificate
     stating that the deposit was not made by the Company with the intent of
     preferring the Holders of notes over the other creditors of the Company
     with the intent of defeating, hindering, delaying or defrauding creditors
     of the Company or others; and

          (8) the Company must deliver to the Trustee an Officers' Certificate
     and an Opinion of Counsel, stating that all conditions precedent relating
     to the Legal Defeasance or the Covenant Defeasance have been complied with.

SATISFACTION AND DISCHARGE

     The Company may discharge its obligations under the Indenture while notes
remain outstanding if (a) all outstanding notes have been delivered for
cancellation, (b) all outstanding notes have become due and payable at their
scheduled maturity or (c) all outstanding notes are scheduled for redemption,
and the Company has deposited with the Trustee an amount sufficient to pay and
discharge all outstanding notes, not previously delivered for cancellation, on
the date of their scheduled maturity or the scheduled date of redemption.

AMENDMENT, SUPPLEMENT AND WAIVER

     Except as provided below, the Indenture, the notes and Subsidiary
Guarantees may be amended with the consent of the Holders of at least a majority
in principal amount of the notes then outstanding (including consents obtained
in connection with a purchase of, or tender offer or exchange offer for, notes),
and any existing default or compliance with any provision of the Indenture, the
notes or the Subsidiary Guarantees may be waived with the consent of the Holders
of a majority in principal amount of the then outstanding notes (including
consents obtained in connection with a tender offer or exchange offer for
notes).

     Without the consent of each Holder affected, an amendment, supplement or
waiver may not (with respect to any notes held by a non-consenting Holder):

          (1) reduce the principal amount of notes whose Holders must consent to
     an amendment, supplement or waiver;

          (2) reduce the principal of or change the fixed maturity of any note
     or alter the provisions with respect to the redemption of the notes (other
     than provisions relating to the covenants described above under the caption
     "-- Repurchase at the Option of Holders");

          (3) reduce the rate of or change the time for payment of interest on
     any note;

                                        61


          (4) waive a Default or Event of Default in the payment of principal of
     or premium, if any, or interest on the notes (except a rescission of
     acceleration of the notes by the Holders of at least a majority in
     aggregate principal amount of the notes and a waiver of the payment default
     that resulted from such acceleration);

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

          (6) make any change in the provisions of the Indenture relating to
     waivers of past Defaults or the rights of Holders of notes to receive
     payments of principal of or premium, if any, or interest on the notes
     (except as permitted by clause (7) below);

          (7) waive a redemption payment with respect to any note (other than a
     payment required by one of the covenants described above under the caption
     "-- Repurchase at the Option of Holders");

          (8) modify any Subsidiary Guarantee in any manner adverse to Holders
     of the notes or release any Guarantor from its obligations under its
     Subsidiary Guarantee except in accordance with the terms of the Indenture;

          (9) make any change in the ranking of the notes or the Subsidiary
     Guarantees in a manner adverse to the Holders of the notes or the
     Subsidiary Guarantees; or

          (10) make any change in the preceding amendment, supplement and waiver
     provisions.

     Notwithstanding the preceding, without the consent of any Holder of notes,
the Company, the Guarantors and the Trustee may amend or supplement the
Indenture, the notes or the Subsidiary Guarantees:

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

          (2) to provide for uncertificated notes in addition to or in place of
     certificated notes;

          (3) to provide for the assumption of the Company's or a Guarantor's
     obligations to Holders of notes in the case of a merger or consolidation or
     sale of all or substantially all of the Company's or a Guarantor's
     properties or assets in compliance with the Indenture;

          (4) to add or release Guarantors in compliance with the Indenture;

          (5) to make any change that would provide any additional rights or
     benefits to the Holders of notes or that does not adversely affect the
     legal rights under the Indenture of any such Holder;

          (6) to secure the notes, including pursuant to the requirements of the
     covenant described above under the caption "-- Certain Covenants -- Liens;"

          (7) to comply with requirements of the SEC in order to effect or
     maintain the qualification of the Indenture under the Trust Indenture Act;
     or

          (8) to provide for the issuance of Exchange Securities or Additional
     Notes.

CONCERNING THE TRUSTEE

     If the Trustee becomes a creditor of the Company or any Guarantor, the
Indenture limits its right 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;
however, if it acquires any conflicting interest after a Default has occurred
and is continuing it must eliminate such conflict within 90 days, apply to the
SEC for permission to continue or resign.

     The Holders of a majority in principal amount of the then outstanding notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur and be continuing, the Trustee will be required, in the exercise of
its power, to use the degree of care of a prudent person 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

                                        62


Holder shall have offered to the Trustee security and indemnity satisfactory to
it against any loss, liability or expense as provided in the Indenture.

GOVERNING LAW

     The Indenture, the notes and the Subsidiary Guarantees will be governed by,
and construed in accordance with, the laws of the State of New York.

CERTAIN DEFINITIONS

     Set forth below are certain defined terms used in the Indenture. Reference
is made to the Indenture for a full disclosure of all such terms, as well as any
other capitalized terms used herein for which no definition is provided.

     "ACNTA" means (without duplication), as of the date of determination:

          (a) the sum of:

             (i) discounted future net revenue from proved crude oil and natural
        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
        Company's most recently completed fiscal year, which reserve report is
        prepared or reviewed 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 year-end 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 year end) due to
           exploration, development or exploitation, production or other
           activities which reserves were not reflected in such year-end reserve
           report,

        in the case of the determination made under each of clauses (A) and (B)
        above, 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 year-end
           reserve report produced or disposed of since the date of such
           year-end reserve report, and

                (D) reductions in the estimated crude oil and natural gas
           reserves of the Company and its Restricted Subsidiaries reflected in
           such year-end reserve report since the date of such year-end 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 year-end reserve report, in each
           case calculated in accordance with SEC guidelines (utilizing the
           prices utilized in such year-end reserve report);

                                        63


        provided, however, that, in the case of each of the determinations made
        pursuant to clauses (A) through (D), such increases and decreases shall
        be as 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 if the amount of ACNTA is required to be
        computed under the Indenture in connection with the calculation of
        clause (1) of the second paragraph under the covenant captioned
        "-- Certain Covenants -- Incurrence of Indebtedness;"

             (ii) 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 date
        of the Company's latest annual or quarterly financial statements;

             (iii) the Net Working Capital on a date no earlier than the date of
        the Company's latest annual or quarterly financial statements; and

             (iv) the greater of (I) the net book value on a date no earlier
        than the date of the Company's latest annual or quarterly financial
        statements and (II) the appraised value, as estimated by independent
        appraisers within the immediately preceding 12 months, of other tangible
        assets of the Company and its Restricted Subsidiaries (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:

             (i) minority interests;

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

             (iii) 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, royalty interests, overriding royalty
        interests, net profits 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;

             (iv) the discounted future net revenue, calculated in accordance
        with SEC guidelines (utilizing the same prices utilized in the Company's

an Officers' Certificate that also certifies that such designation complied with
the preceding conditions and was permitted by the covenant described above under
the caption "-- Certain Covenants -- Restricted Payments" in which case such
designation shall be effective as of the date specified in such resolution. If,

such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary of the
Company as of such date and, if such Indebtedness is not permitted to be
incurred as of such date under the covenant described under the caption
"-- Certain Covenants -- Incurrence of Indebtedness," the Company shall be in
default of such covenant.

     The Board of Directors of the Company may at any time designate any
Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such
designation shall be deemed to be an incurrence of Indebtedness by a Restricted
Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted
Subsidiary and such designation shall only be permitted if (1) such Indebtedness
is permitted under the covenant described under the caption "-- Certain
Covenants -- Incurrence of Indebtedness," calculated on a pro forma basis as if
such designation had occurred at the beginning of the four-quarter reference

     required payments of principal, including payment at final maturity, in
     respect thereof, by (b) the number of years (calculated to the nearest
     one-twelfth) that will elapse between such date and the making of such
     payment; by

          (2) the then outstanding principal amount of such Indebtedness.

     "Wholly Owned Restricted Subsidiary" of any Person means a Restricted
Subsidiary of such Person all of the outstanding Capital Stock of which (other
than directors' qualifying shares) shall at the time be owned by such Person

REGISTRATION RIGHTS

     The Company entered into a registration rights agreement with the initial
purchasers. Under the registration rights agreement, the Company agreed for the
benefit of the holders of the old notes, that it would, at its cost and subject
to certain exceptions, consummate the exchange offer described in this
prospectus. For details regarding the exchange offer, please read "The Exchange
Offer."

     Pursuant to the registration rights agreement, the Company agreed to:

          (1) within 90 days after April 8, 2005, file a registration statement
     (the "Exchange Offer Registration Statement") with the SEC with respect to
     a registered offer (the "Registered Exchange Offer") to exchange each of
     the old notes for the new notes having terms substantially identical in all
     material respects to the old notes (except that the new notes will not
     contain terms with respect to transfer restrictions);

          (2) use its reasonable best efforts to cause the Exchange Offer
     Registration Statement to be declared effective under the Securities Act
     within 180 days after April 8, 2005;

          (3) promptly following the effectiveness of the Exchange Offer
     Registration Statement (the "Effectiveness Date"), offer the new notes in
     exchange for surrender of the old notes; and
                                        81


          (4) keep the Registered Exchange Offer open for not less than 20
     business days (or longer, if required by applicable law) after the date
     notice of the Registered Exchange Offer is mailed to the holders of the old
     notes.

     Under the registration rights agreement, the Company is required to allow
Participating Broker-Dealers and other Persons, if any, with similar prospectus
delivery requirements to use the prospectus contained in the Exchange Offer
Registration Statement in connection with the resale of such new notes for 180
days following the effective date of such Exchange Offer Registration Statement
(or such shorter period during which Participating Broker-Dealers are required
by law to deliver such prospectus).

     In the event that:

          (1) any change in law or applicable interpretations of the staff of
     the SEC do not permit the Company to effect the Registered Exchange Offer;
     or

          (2) for any other reason, the Registered Exchange Offer is not
     consummated within 220 days after April 8, 2005; or

          (3) any of the initial purchasers shall notify the Company following
     consummation of the Registered Exchange Offer that any of the old notes
     held by it are not eligible to be exchanged for new notes in the Registered
     Exchange Offer; or

          (4) certain holders are prohibited by law or SEC policy from
     participating in the Registered Exchange Offer or may not resell the new
     notes acquired by them in the Registered Exchange Offer to the public
     without delivering a prospectus, the Company will, subject to certain
     exceptions:

             (a) promptly file a shelf registration statement (the "Shelf
        Registration Statement") covering resales of the old notes or the new
        notes, as the case may be;

             (b) (i) in the case of clause (1) above, use its reasonable best
        efforts to cause the Shelf Registration Statement to be declared
        effective under the Securities Act on or prior to the 180th calendar day
        following April 8, 2005 and (ii) in the case of clause (2), (3) or (4)
        above, use its reasonable best efforts to cause the Shelf Registration
        Statement to be declared effective under the Securities Act on or prior
        to the 90th day after the date on which the Shelf Registration Statement
        is required to be filed; and

             (c) use its reasonable best efforts to keep the Shelf Registration
        Statement effective until the earliest of (i) the time when the old
        notes covered by the Shelf Registration Statement can be sold pursuant
        to Rule 144 without any limitations under clauses (c), (e), (f) and (h)
        of Rule 144, (ii) two years from the effective date of the Shelf
        Registration Statement and (iii) the date on which all notes registered
        thereunder are disposed of in accordance therewith.

     The Company 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 new notes, as the case may
be. A Holder selling such old notes or new 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).

     The Company will pay additional cash interest on the applicable notes,
subject to certain exceptions:

          (1) if the Exchange Offer Registration Statement or, if obligated to
     file a Shelf Registration Statement pursuant to clause (ii)(A) above, a
     Shelf Registration Statement, is not declared effective by the SEC on or
     prior to the 180th day after April 8, 2005;

                                        82


          (2) if the Exchange Offer is not consummated on or prior to the 40th
     day after the Exchange Offer Registration Statement is declared effective;

          (3) if obligated to file the Shelf Registration Statement pursuant to
     clause (ii)(B) above, the Company fails to file the Shelf Registration
     Statement with the SEC on or prior to the 30th day after the date (the
     "Shelf Filing Date") on which the obligation to file a Shelf Registration
     Statement arises;

          (4) if obligated to file a Shelf Registration Statement, the Shelf
     Registration Statement is not declared effective on or prior to the 90th
     day after the Shelf Filing Date; or

          (5) after the Exchange Offer Registration Statement 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) (each such event referred to in the preceding
     clauses (1) through (5) a "Registration Default");

from and including the date on which any such Registration Default shall occur
to, but excluding, the date on which all Registration Defaults have been cured.

     The rate of the additional interest will be 0.50% per year for the first
90-day period immediately following the occurrence of a Registration Default,
and such rate will increase by an additional 0.50% per year with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum additional interest rate of 1.50% per year. The Company will pay 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 new notes. We will not be required to pay additional
interest for more than one Registration Default at any given time. Following the
cure of all Registration Defaults, the accrual of additional interest will
cease.

     All references in the Indenture and in this "Description of the New Notes,"
in any context, to any interest or other amount payable on or with respect to
the new notes shall be deemed to include any additional interest payable
pursuant to the registration rights agreement.

                                        83


                      GLOBAL SECURITIES; BOOK-ENTRY SYSTEM

THE GLOBAL SECURITIES

     The notes will initially be represented by one or more permanent global
notes in definitive, fully registered book-entry form (the "global securities")
which will be registered in the name of Cede & Co., as nominee of DTC, or such
other name as may be requested by an authorized representative of DTC. The
global notes will be deposited with the Trustee as custodian for DTC and may not
be transferred except as a whole by DTC to a nominee of DTC or by a nominee of
DTC to DTC or another nominee of DTC or by DTC or any nominee to a successor of
DTC or a nominee of such successor.

     We expect that pursuant to procedures established by DTC (a) upon deposit
of the global securities, DTC or its custodian will credit on its internal
system portions of the global securities which will contain the corresponding
respective amount of the global securities to the respective accounts of persons
who have accounts with such depositary and (b) ownership of the notes will be
shown on, and the transfer of ownership thereof will be affected only through,
records maintained by DTC or its nominee (with respect to interests of
participants (as defined below)) and the records of participants (with respect
to interests of persons other than participants). Such accounts initially will
be designated by or on behalf of the initial purchasers and ownership of
beneficial interests in the global securities will be limited to persons who
have accounts with DTC (the "participants") or persons who hold interests
through participants. Noteholders may hold their interests in a global security
directly through DTC if they are participants in such system, or indirectly
through organizations which are participants in such system.

     So long as DTC or its nominee is the registered owner or holder of any of
the notes, DTC or such nominee will be considered the sole owner or holder of
such notes represented by such global securities for all purposes under the
indenture and under the notes represented thereby. No beneficial owner of an
interest in the global securities will be able to transfer such interest except
in accordance with the applicable procedures of DTC.

CERTAIN BOOK-ENTRY PROCEDURES FOR THE GLOBAL SECURITIES

     The operations and procedures of DTC is solely within the control of DTC
and are subject to change by them from time to time. Investors are urged to
contact the DTC or its participants directly to discuss these matters.

     DTC has advised us that it is:

     - a limited purpose trust company organized under the laws of the State of
       New York;

     - a "banking organization" within the meaning of the New York Banking Law;

     - a member of the Federal Reserve System;

     - a "clearing corporation" within the meaning of the New York Uniform
       Commercial Code, as amended; and

     - a "clearing agency" registered pursuant to Section 17A of the Securities
       Exchange Act of 1934.

     DTC was created to hold securities for its participants (collectively, the
"participants") and to facilitate the clearance and settlement of securities
transactions, such as transfers and pledges, between participants through
electronic book-entry changes to the accounts of its participants, thereby
eliminating the need for physical transfer and delivery of certificates. DTC's
participants include securities brokers and dealers (including the initial
purchasers), banks and trust companies, clearing corporations and certain other
organizations. DTC is a wholly owned subsidiary of The Depository Trust &
Clearing Corporation, which is owned by a number of direct participants of DTC
and by the New York Stock Exchange, Inc., the American Stock Exchange, LLC and
the National Association of Securities Dealers, Inc. Indirect access to DTC's
system is also available to other entities such as banks, brokers, dealers and
trust companies (collectively, the "indirect participants") that clear through
or maintain a custodial relationship with a participant, either

                                        84


directly or indirectly. Investors who are not participants may beneficially own
securities held by or on behalf of DTC only through participants or indirect
participants. The rules applicable to DTC and its participants are on file with
the SEC.

     The laws of some jurisdictions may require that some purchasers of
securities take physical delivery of those securities in definitive form.
Accordingly, the ability to transfer beneficial interests in notes represented
by a global security to those persons may be limited. In addition, because DTC
can act only on behalf of its participants, who in turn act on behalf of persons
who hold interests through participants, the ability of a person holding a
beneficial interest in a global security to pledge or transfer that interest to
persons or entities that do not participate in DTC's system, or to otherwise
take actions in respect of that interest, may be affected by the lack of a
physical security in respect of that interest.

     So long as DTC or its nominee is the registered owner of a global security,
DTC or that nominee, as the case may be, will be considered the sole legal owner
or holder of the notes represented by that global security for all purposes of
the notes and the indenture. Except as provided below, owners of beneficial
interests in a global security will not be entitled to have the notes
represented by that global security registered in their names, will not receive
or be entitled to receive physical delivery of certificated securities, and will
not be considered the owners or holders of the notes represented by that
beneficial interest under the indenture for any purpose, including with respect
to the giving of any direction, instruction or approval to the Trustee. To
facilitate subsequent transfers, all global securities that are deposited with,
or on behalf of, DTC will be registered in the name of DTC's nominee, Cede & Co.
The deposit of global securities with, or on behalf of, DTC and their
registration in the name of Cede & Co. effect no change in beneficial ownership.
We understand that DTC has no knowledge of the actual beneficial owners of the
securities. Accordingly, each holder owning a beneficial interest in a global
security must rely on the procedures of DTC and, if that holder is not a
participant or an indirect participant, on the procedures of the participant
through which that holder owns its interest, to exercise any rights of a holder
of notes under the indenture or that global security. We understand that under
existing industry practice, in the event that we request any action of holders
of notes, or a holder that is an owner of a beneficial interest in a global
security desires to take any action that DTC, as the holder of that global
security, is entitled to take, DTC would authorize the participants to take that
action and the participants would authorize holders owning through those
participants to take that action or would otherwise act upon the instruction of
those holders.

     Conveyance of notices and other communications by DTC to its direct
participants, by its direct participants to indirect participants and by its
direct and indirect participants to beneficial owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.

     Neither DTC nor Cede & Co. will consent or vote with respect to the global
securities unless authorized by a direct participant under DTC's procedures.
Under its usual procedures, DTC will mail an omnibus proxy to us as soon as
possible after the applicable record date. The omnibus proxy assigns Cede &
Co.'s consenting or voting rights to those direct participants of DTC to whose
accounts the securities are credited on the applicable record date, which are
identified in a listing attached to the omnibus proxy.

     Neither we nor the Trustee will have any responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial
interests in the global securities by DTC, or for maintaining, supervising or
reviewing any records of DTC relating to those beneficial interests.

     Payments with respect to the principal of and premium, if any, liquidated
damages, if any, and interest on a global security will be payable by the
Trustee to or at the direction of DTC or its nominee in its capacity as the
registered holder of the global security under the Indenture. Under the terms of
the Indenture, we and the Trustee may treat the persons in whose names the
notes, including the global securities, are registered as the owners thereof for
the purpose of receiving payment thereon and for any and all other purposes
whatsoever. Accordingly, neither we nor the Trustee has or will have any
responsibility or liability for the payment of those amounts to owners of
beneficial interests in a global security. It is our understanding that DTC's
practice is to credit the direct participants' accounts upon DTC's receipt of
funds and corresponding detail information from us or the Paying Agent on the
applicable payment date in accordance with their respective holdings shown on
                                        85


DTC's records. Payments by the participants and the indirect participants to the
owners of beneficial interests in a global security will be governed by standing
instructions and customary industry practice and will be the responsibility of
the participants and indirect participants and not of DTC, us or the Trustee,
subject to statutory or regulatory requirements in effect at the time.

     Transfers between participants in DTC will be effected in accordance with
DTC's procedures, and, except for trades involving only the Euroclear System as
operated by Euroclear Bank S.A./N.V., or Euroclear, or Clearstream Banking, S.A.
of Luxembourg, or Clearstream Luxembourg, such transfers will be settled in
same-day funds. Transfers between participants in Euroclear or Clearstream
Luxembourg will be effected in the ordinary way in accordance with their
respective rules and operating procedures.

     Subject to compliance with the transfer restrictions applicable to the
notes, cross-market transfers between the participants in DTC, on the one hand,
and Euroclear or Clearstream Luxembourg participants, on the other hand, will be
effected through DTC in accordance with DTC's rules on behalf of Euroclear or
Clearstream Luxembourg, as the case may be, by its respective depositary;
however, those cross-market transactions will require delivery of instructions
to Euroclear or Clearstream Luxembourg, as the case may be, by the counterparty
in that system in accordance with the rules and procedures and within the
established deadlines (Brussels time) of that system. Euroclear or Clearstream
Luxembourg, as the case may be, will, if the transaction meets its settlement
requirements, deliver instructions to its respective depositary to take action
to effect final settlement on its behalf by delivering or receiving interests in
the relevant global securities in DTC, and making or receiving payment in
accordance with normal procedures for same-day funds settlement applicable to
DTC. Euroclear participants and Clearstream Luxembourg participants may not
deliver instructions directly to the depositaries for Euroclear or Clearstream
Luxembourg.

     Because of time zone differences, the securities account of a Euroclear or
Clearstream Luxembourg participant purchasing an interest in a global security
from a participant in DTC will be credited, and any such crediting will be
reported to the relevant Euroclear or Clearstream Luxembourg participant, during
the securities settlement processing day (which must be a business day for
Euroclear and Clearstream Luxembourg) immediately following the settlement date
of DTC. Cash received in Euroclear or Clearstream Luxembourg as a result of
sales of interests in a global security by or through a Euroclear or Clearstream
Luxembourg participant to a participant in DTC will be received with value on
the settlement date of DTC but will be available in the relevant Euroclear or
Clearstream Luxembourg cash account only as of the business day for Euroclear or
Clearstream Luxembourg following DTC's settlement date.

     Although DTC has agreed to the foregoing procedures to facilitate transfers
of interests in the global securities among participants in DTC, it is under no
obligation to perform or to continue to perform those procedures, and those
procedures may be discontinued at any time. Neither we nor the Trustee will have
any responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.

     DTC may discontinue providing its services as securities depositary with
respect to the global securities at any time by giving reasonable notice to us
or the Trustee. Under such circumstances, if a successor securities depositary
is not obtained, certificates for the securities are required to be printed and
delivered.

     We may decide to discontinue use of the system of book-entry transfers
through DTC or a successor securities depositary. In that event, certificates
for the securities will be printed and delivered.

     We have provided the foregoing information with respect to DTC to the
financial community for information purposes only. Although we obtained the
information in this section and elsewhere in this prospectus concerning DTC and
its book-entry system from sources that we believe are reliable, we take no
responsibility for the accuracy of such information.

            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following discussion of the material U.S. federal income tax
considerations relevant to the exchange of new notes for old notes pursuant to
the exchange offer does not purport to be a complete analysis of all potential
tax effects. The discussion is based upon the Internal Revenue Code of 1986, as
amended, Treasury Regulations, Internal Revenue Service rulings and
pronouncements and judicial decisions now in effect, all of which may be subject
to change at any time by legislative, judicial or administrative action. These
changes may be applied retroactively in a manner that could adversely affect a
holder of new notes. The description does not consider the effect of any
applicable foreign, state, local or other tax laws or estate or gift tax
considerations.

     The exchange of new notes for old notes pursuant to the exchange offer will
not be a taxable exchange for U.S. federal income tax purposes. A holder will
not recognize any taxable gain or loss as a result of the exchange and will have
the same tax basis and holding period in the new notes as the holder had in the
old notes immediately before the exchange.

                                        87


                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives new 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 new 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 new notes received in exchange for old notes where
such old notes were acquired as a result of market-making activities or other
trading activities. We have agreed that, for 180 days after the consummation of
the exchange offer, we will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale. In
addition, until           , 2005, all dealers effecting transactions in the new
notes may be required to deliver a prospectus.

     We will not receive any proceeds from any sale of new notes by
broker-dealers. New 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 new notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer or the purchasers of any such new notes. Any broker-dealer that
resells new notes that were received by it for its own account pursuant to the
exchange offer and any broker or dealer that participates in a distribution of
such new notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of new notes and any
commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The enclosed letter of
transmittal states that, by acknowledging that it will deliver and be 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 consummation of the exchange offer, 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 all expenses incident to the
exchange offer (including the expenses of one counsel for the holders of the
notes) other than commissions or concessions of any brokers or dealers and will
indemnify the holders of the old notes (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.

     Following completion of the exchange offer, we may, in our sole discretion,
commence one or more additional exchange offers to holders of old notes who did
not exchange their old notes for new notes in the exchange offer on terms which
may differ from those contained in this prospectus and the enclosed letter of
transmittal. This prospectus, as it may be amended or supplemented from time to
time, may be used by us in connection with any additional exchange offers. These
additional exchange offers may take place from time to time until all
outstanding old notes have been exchanged for new notes, subject to the terms
and conditions in the prospectus and letter of transmittal distributed by us in
connection with these additional exchange offers.

                                        88


                                 LEGAL MATTERS

     The validity of the new notes and certain other matters will be passed upon
for us by Andrews Kurth LLP, Houston, Texas.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

  DELAWARE REGISTRANTS

     KCS Energy, Inc., KCS Resources, Inc. and KCS Energy Services, Inc. are
incorporated under the laws of the State of Delaware. Section 145(a) of the
Delaware General Corporation Law, or DGCL, authorizes a corporation to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, other than an
action by or in the right of the corporation, because such person is or was a
director, officer, employee or agent of the corporation or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation or other enterprise, against expenses, including attorneys'
fees, judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such suit or proceeding if he acted in good
faith and in a manner he 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 reason to believe his conduct was unlawful. Similar indemnity
is authorized for such persons by Section 145(b) of the DGCL against expenses,
including attorneys' fees, actually and reasonably incurred in defense or
settlement of any such threatened, pending or completed action or suit by or in
the right of the corporation if such person acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and provided further that, unless a court of competent jurisdiction
otherwise provides, such person shall not have been adjudged liable to the
corporation. Any such indemnification may be made only as authorized in each
specific case upon a determination that indemnification is proper because the
indemnitee has met the applicable standard of conduct by (i) a majority vote of
disinterested directors, or (ii) a committee of such directors designated by a
majority vote of such directors, or (iii) if there are no such directors, by
independent legal counsel in a written opinion, or (iv) by the stockholders.

     Section 145(g) of the DGCL further authorizes a corporation to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such, whether or not the corporation would otherwise have the
power to indemnify him. Further, Article IX(b)(4) of KCS Energy Inc.'s Restated
Certificate of Incorporation provides that KCS Energy, Inc. may secure insurance
on behalf of any of its officers and directors against any expense, liability or
loss, whether or not it would have the power to indemnify such officer or
director against such expense, liability or loss under the DGCL. KCS Energy,
Inc. maintains policies insuring its and its subsidiaries' officers and
directors against certain liabilities and expenses for actions taken in such
capacities and under certain stated conditions, including liabilities under the
Securities Act of 1933, as amended.

     Article IX(b)(1) of KCS Energy, Inc.'s Restated Certificate of
Incorporation provides, in substance, that its directors and officers shall be
indemnified to the extent permitted by Section 145 of the DGCL. Additionally,
Article IX(a) of its Restated Certificate of Incorporation (which is
substantially similar to Section 102(b)(7) of the DGCL) eliminates in certain
circumstances the monetary liability of its directors for a breach of their
fiduciary duty as directors. These provisions do not eliminate the liability of
a director:

     - for a breach of the director's duty of loyalty to KCS Energy, Inc. or its
       stockholders;

     - for acts or omissions by the director not in good faith or involving
       intentional misconduct or a knowing violation of law;

     - under Section 174 of the DGCL, which relates to the declaration of
       dividends and purchase or redemption of shares in violation of the DGCL;
       and

     - for any transaction from which the director derived an improper personal
       benefit.

                                       II-1


     The Certificates of Incorporation, as amended, of KCS Resources, Inc. and
KCS Energy Services, Inc. contain similar provisions as the provisions contained
in Article IX(a) of KCS Energy, Inc.'s Restated Certificate of Incorporation
regarding the elimination in certain circumstances of monetary liability of
directors for a breach of fiduciary duty.

  NEW JERSEY REGISTRANT

     Proliq, Inc. is incorporated under the laws of the State of New Jersey.
Section 3-5, Title 14A of the New Jersey Business Corporation Act empowers a
corporation to indemnify any person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative, arbitrative or investigative, by reason
of the fact that he is or was a director, officer, employee or agent of the
corporation or is or was serving at the request of the corporation as a
director, officer, trustee, employee or agent of another related corporation or
enterprise, against reasonable costs, disbursements and counsel fees and amounts
paid or incurred in satisfaction of such action, suit or proceeding if such
person acted in good faith and in a manner he reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal proceeding, had no reasonable cause to believe that such conduct was
unlawful. In connection with any proceeding by or in the right of the
corporation, no indemnification may be made in respect to any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
corporation, unless and only to the extent that the Superior Court or the court
in which such action or suit was brought shall determine that despite the
adjudication of liability, but in view of all circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses which
the Superior Court or the other court shall deem proper. No indemnification
shall be made to or on behalf of such a person if a judgment or other final
adjudication adverse to the person establishes that his acts or omissions (i)
were in breach of his duty of loyalty to the corporation or its shareholders,
(ii) were not in good faith or involved a knowing violation of law or (iii)
resulted in receipt by the person of an improper personal benefit.

  TEXAS REGISTRANT

     Medallion California Properties Company ("MCPC") is incorporated under the
laws of the State of Texas. Article 2.02-1 of the Texas Business Corporation Act
provides that any director or officer of a Texas corporation may be indemnified
against judgments, penalties, fines, settlements and reasonable expenses
actually incurred by the person in connection with or in defending any action,
suit or proceeding, whether civil, criminal, administrative, arbitrative or
investigative, in which he was, is, or is threatened to be made a named
defendant by reason of his position as a director or officer of the corporation,
provided that (i) he conducted himself in good faith, (ii) he reasonably
believed that, in the case of conduct in his official capacity as a director or
officer of the corporation, such conduct was in the corporation's best
interests; and, in all other cases, that such conduct was at least not opposed
to the corporation's best interests, and (iii) in the case of a criminal
proceeding, he had no reasonable cause to believe his conduct was unlawful. If a
director or officer is wholly successful, on the merits or otherwise, in
connection with such a proceeding, such indemnification is mandatory. In
connection with any action, suit or proceeding in which a director or officer is
(x) found liable on the basis that personal benefit was improperly received by
him, whether or not the benefit resulted from an action taken in his official
capacity, or (y) found liable to the corporation, the indemnification is limited
to reasonable expenses actually incurred by him in connection with the
proceeding and will not be made in respect of any proceeding in which he is
found liable for willful or intentional misconduct in the performance of his
duty to the corporation.

     Article IX of the Articles of Incorporation, as amended, of MCPC generally
provides that it will indemnify its directors and its former directors and may
indemnify its officers and its former officers against any losses, damages,
claims or liabilities to which they may become subject or which they may incur
as a result of being or having been an officer or director, and shall advance to
them or reimburse them for expenses incurred in connection therewith, to the
maximum extent permitted by law. Directors and officers may be indemnified
against judgments, penalties (including excise and similar taxes), fines,
settlements and reasonable expenses actually incurred by the person in
connection with a proceeding; but if the person is found

                                       II-2


liable to MCPC or is found liable on the basis that personal benefit was
improperly received by the person, the indemnification (i) is limited to
reasonable expenses actually incurred by the person in connection with the
proceeding and (ii) shall not be made in respect of any proceeding in which the
person shall have been found liable for willful or intentional misconduct in the
performance of his duty to MCPC.

     Reference is made to Item 22 for our undertakings with respect to
indemnification for liabilities arising under the Securities Act.

  supplementally a copy of any omitted schedule to the SEC upon request.

ITEM 22.  UNDERTAKINGS.

     Each undersigned registrant hereby undertakes:

          (a)(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% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement; provided, however, that paragraphs (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 section 15(d) of the Securities Exchange Act
        of 1934 that are incorporated by reference in the registration
        statement.

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

          (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) 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 (and, where applicable, each filing of an employee benefit plan's
     annual report pursuant to section 15(d) of the Securities Exchange Act of
     1934) that is incorporated by reference in the registration statement shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

          (c) To respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Items 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.

                                       II-5


          (d) 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 this registration statement
     when it became effective.

          (e) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the registrant, we have been advised that in the
     opinion of the Securities and Exchange Commission such indemnification is
     against public policy and is, therefore, unenforceable. In the event that a
     claim for indemnification against such liabilities (other than the payment
     by the registrant of expenses incurred or paid by a director, officer or
     controlling person of the registrant in the successful defense of any
     action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered, the
     registrant will, unless in the opinion of its counsel the matter has been
     settled by controlling precedent, submit to a court of appropriate
     jurisdiction the question 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.

                                       II-6
