                               THE EXCHANGE OFFER

     On April 6, 2001, we completed a private offering of the outstanding notes.
We entered into a registration rights agreement with the initial purchasers in
the private offering in which we agreed to deliver to you this prospectus and to
use our best efforts to complete the exchange offer within 240 days after the
date we issued the outstanding notes.

Exchange Offer......................     We are offering to exchange new notes
                                         for outstanding notes.

Expiration Date.....................     The exchange offer will expire at 5:00
                                         p.m. New York City time, on July 12,
                                         2001, unless we decide to extend it.

Condition to the Exchange Offer.....     The registration rights agreement does
                                         not require us to accept outstanding
                                         notes for exchange if the exchange
                                         offer or the making of any exchange by
                                         a holder of the outstanding notes would
                                         violate any applicable law or
                                         interpretation of the staff of the
                                         Securities and Exchange Commission. A
                                         minimum aggregate principal amount of
                                         outstanding notes being tendered is not
                                         a condition to the exchange offer.

                                  RISK FACTORS

     In addition to the other information set forth elsewhere or incorporated by
reference in this prospectus, the following factors relating to our company and
the exchange offer and the new notes should be considered carefully in deciding
whether to participate in the exchange offer.

RISKS RELATED TO OUR BUSINESS

  Oil and Gas Prices Are Volatile. A Decline in Prices Could Adversely Affect
  Our Financial Results, Cash Flows, Access to Capital and Ability to Grow.

     Our revenues, operating results, profitability, future rate of growth and
the carrying value of our oil and gas properties depend primarily upon the
prices we receive for our oil and gas. Prices also affect the amount of cash
flow available for capital expenditures and our ability to borrow money or raise
additional capital. The amount we can borrow from banks is subject to
semi-annual redeterminations based on current prices at the time of
redetermination. In addition, we may have ceiling test writedowns if prices
decline significantly from present levels.

     Historically, the markets for oil and gas have been volatile, and they are
likely to continue to be volatile. Wide fluctuations in oil and gas prices may
result from relatively minor changes in the supply of and demand for oil and
natural gas, market uncertainty and other factors that are beyond our control,
including:

     - worldwide and domestic supplies of oil and gas;

     - weather conditions;

     - the level of consumer demand;

     - the price and availability of alternative fuels;

     - the availability of pipeline capacity;

     - the price and level of foreign imports;

     - domestic and foreign governmental regulations and taxes;

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

     - political instability or armed conflict in oil producing regions; and

     - the overall economic environment.

     These factors and the volatility of the energy markets make it extremely
difficult to predict future oil and gas price movements with any certainty.
Declines in oil and gas prices would not only reduce revenue, but could reduce
the amount of oil and gas that we can produce economically and, as a result,
could have a material adverse effect on our financial condition, results of
operations and reserves. Further, oil and gas prices do not necessarily move in
tandem. Because approximately 91% of our proved reserves are currently natural
gas reserves, we are more susceptible to movements in natural gas prices.

  Our Level of Indebtedness May Adversely Affect Operations, and We May Have
  Difficulty Repaying Long-Term Indebtedness as It Matures.

     As of March 31, 2001, we had long-term indebtedness of $1.1 billion, which
included bank indebtedness of $14.5 million. Our long-term indebtedness
represented 72.6% of our total book

                                        6
   9

capitalization at March 31, 2001. We will continue to be highly leveraged after
this exchange offer. Our level of indebtedness affects our operations in several
ways, including the following:

     - a substantial portion of our cash flows must be used to service our
       indebtedness, and we cannot assure you that our business will generate
       sufficient cash flow from operations to enable us to continue to meet our
       obligations under our indebtedness;

     - a high level of indebtedness increases our vulnerability to general
       adverse economic and industry conditions;

     - the covenants contained in the agreements governing our outstanding
       indebtedness limit our ability to borrow additional funds, dispose of
       assets, pay dividends and make certain investments;

     - our debt covenants may also affect our flexibility in planning for, and
       reacting to, changes in the economy and in our industry; and

     - a high level of indebtedness may impair our ability to obtain additional
       financing in the future for working capital, capital expenditures,
       acquisitions or general corporate and other purposes.

     We may incur additional debt, including significant secured indebtedness,
in order to make future acquisitions or to develop our properties. A higher
level of indebtedness increases the risk that we may default on our debt
obligations. Our ability to meet our debt obligations and to reduce our level of
indebtedness depends on our future performance. General economic conditions, oil
and gas prices and financial, business and other factors affect our operations
and our future performance. Many of these factors are beyond our control. We
cannot assure you that we will be able to generate sufficient cash flow to pay
the interest on our debt or that future working capital, borrowings or equity
financing will be available to pay or refinance such debt. Factors that will
affect our ability to raise cash through an offering of our capital stock or a
refinancing of our debt include financial market conditions, the value of our
assets and our performance at the time we need capital.

     In addition, our bank borrowing base is subject to semi-annual
redeterminations. We could be forced to repay a portion of our bank borrowings
due to redeterminations of our borrowing base. We cannot assure you that we will
have sufficient funds to make such repayments. If we do not have sufficient
funds and are otherwise unable to negotiate renewals of our borrowings or
arrange new financing, we may have to sell significant assets. Any such sale
could have a material adverse effect on our business and financial results.

  Higher Oil and Gas Prices Adversely Affect the Cost and Availability of
  Drilling and Production Services.

     Higher oil and gas prices, such as those we are currently experiencing,
generally stimulate increased demand and result in increased prices for drilling
rigs, crews and associated supplies, equipment and services. We have recently
experienced significantly higher costs for drilling rigs and other related
services and expect such costs to continue to escalate in 2001.

  Our Industry Is Extremely Competitive.

     The energy industry is extremely competitive. This is especially true with
regard to exploration for, and development and production of, new sources of oil
and natural gas. As an independent producer of oil and natural gas, we
frequently compete against companies that are larger and financially stronger in
acquiring properties suitable for exploration, in contracting for drilling
equipment and other services and in securing trained personnel.

  Our Commodity Price Risk Management Activities Have Reduced the Realized
  Prices Received for Our Oil and Gas Sales, and these Transactions May Limit
  Our Realized Oil and Gas Sales Prices in the Future.

     In order to manage our exposure to price volatility in marketing our oil
and gas, we enter into oil and gas price risk management arrangements for a
portion of our expected production. These transactions are limited in life.
While intended to reduce the effects of volatile oil and gas prices, commodity
price risk management transactions may limit the prices we actually realize. We
recorded reductions to oil and gas revenues related to commodity price risk
management activities of $30.6 million in 2000 and $30.5 million in the quarter
ended March 31, 2001. We cannot assure you that we will not experience
additional reductions to oil and gas revenues from our commodity price risk
management.

     In addition, our commodity price risk management transactions may expose us
to the risk of financial loss in certain circumstances, including instances in
which:

     - our production is less than expected;

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

     - the counterparties to our contracts fail to perform the contracts.

     Some of our commodity price risk management arrangements require us to
deliver cash collateral or other assurances of performance to the counterparties
in the event that our payment obligations with respect to our commodity price
risk management transactions exceed certain levels. Our collateral requirement
for these activities at March 13, 2001 was $12.0 million, represented by a
letter of credit. Future collateral requirements are uncertain, but will depend

  Estimates of Oil and Gas Reserves Are Uncertain and Inherently Imprecise.

     This prospectus contains or incorporates by reference estimates of our
proved reserves and the estimated future net revenues from our proved reserves,
including those acquired in the Gothic acquisition. These estimates are based
upon various assumptions, including assumptions required by the Securities and
Exchange Commission relating to oil and gas prices, drilling and operating
expenses, capital expenditures, taxes and availability of funds. The process of
estimating oil and gas reserves is complex. The process involves significant
decisions and assumptions in the evaluation of available geological,
geophysical, engineering and economic data for each reservoir. Therefore, these
estimates are inherently imprecise.

     Actual future production, oil and gas prices, revenues, taxes, development
expenditures, operating expenses and quantities of recoverable oil and gas
reserves most likely will vary from these estimates. Such variations may be
significant and could materially affect the estimated quantities and present
value of our proved reserves. In addition, we may adjust estimates of proved
reserves to reflect production history, results of exploration and development
drilling, prevailing oil and gas prices and other factors, many of which are
beyond our control. Our properties may also be susceptible to hydrocarbon
drainage from production by operators on adjacent properties.

     At December 31, 2000, approximately 30% (27% on a pro forma basis for the
Gothic acquisition) by volume of our estimated proved reserves were undeveloped.
Recovery of undeveloped reserves requires significant capital expenditures and
successful drilling operations. The estimates of these reserves include the
assumption that we will make significant capital expenditures to develop the
reserves, including $216 million ($235 million on a pro forma basis for the
Gothic acquisition) in 2001. Although we have prepared estimates of our oil and
gas reserves and the costs associated with these reserves in accordance with
industry standards, we cannot assure you that the estimated costs are accurate,
that development will occur as scheduled or that the results will be as
estimated.

     You should not assume that the present values referred to or incorporated
by reference in this prospectus represent the current market value of our
estimated oil and gas reserves. In accordance with SEC requirements, the
estimates of our present values are based on prices and costs as of the date of
the estimates. The combined December 31, 2000 present values pro forma for
Gothic are based on combined weighted average oil and gas prices of $26.42 per
barrel of oil and $10.13 per mcf of natural gas, compared to our weighted
average prices of $24.72 per barrel of oil and $2.25 per mcf of natural gas used
in computing Chesapeakes's December 31, 1999 present value. Actual future prices
and costs may be materially higher or lower than the prices and costs as of the
date of an estimate. A change in price of $0.10 per mcf and $1.00 per barrel
would result in:

     - a change in our December 31, 2000 present value of proved reserves of $62
       million and $13 million, respectively; and

     - a change in the December 31, 2000 present value of proved reserves for us
       and Gothic combined of $75 million and $14 million, respectively.

     If the present value of our combined pro forma proved reserves were
calculated using a more recent approximation of NYMEX spot prices of $24.00 per
barrel of oil and $5.00 per mcf of gas, adjusted for our price differentials,
the present value of our combined pro forma proved reserves at December 31, 2000
would have been $3.2 billion.

     Any changes in consumption by oil and gas purchasers or in governmental
regulations or taxation will also affect actual future net cash flows.

     The timing of both the production and the expenses from the development and
production of oil and gas properties will affect both the timing of actual
future net cash flows from proved reserves and their present value. In addition,
the 10% discount factor, which is required by the SEC to be used in calculating
discounted future net cash flows for reporting purposes, is not necessarily the
most accurate discount factor. The effective interest rate at various times and
the risks associated with our business or the oil and gas industry in general
will affect the accuracy of the 10% discount factor.

  If We Are Not Able to Replace Reserves, We May Not Be Able to Sustain
  Production.

     Our future success depends largely upon our ability to find, develop or
acquire additional oil and gas reserves that are economically recoverable.
Unless we replace the reserves we produce through successful development,
exploration or acquisition, our proved reserves will decline over time. In
addition, approximately 30% (27% on a pro forma basis for the Gothic
acquisition) of our total estimated proved reserves at December 31, 2000 were
undeveloped. By their nature, undeveloped reserves are less certain. Recovery of
such reserves will require significant capital expenditures and successful
drilling operations. We cannot assure you that we can successfully find and
produce reserves economically in the future. In addition, we may not be able to
acquire proved reserves at acceptable costs.

  If We Do Not Make Significant Capital Expenditures, We May Not Be Able to
  Replace Reserves.

     Our exploration, development and acquisition activities require substantial
capital expenditures. Historically, we have funded our capital expenditures
through a combination of cash flows from operations, our bank credit facility,
debt and equity issuances and the sale of non-core assets. Future cash flows are
subject to a number of variables, such as the level of production from existing
wells, prices of oil and gas and our success in developing and producing new
reserves. If revenue were to decrease as a result of lower oil and gas prices or
decreased production, and our access to capital were limited, we would have a
reduced ability to replace our reserves. If our cash flow from operations is not
sufficient to fund our capital expenditure budget, there can be no assurance
that additional bank debt, debt or equity issuances or other methods of
financing will be available to meet these requirements.

  Acquisitions Are Subject to the Uncertainties of Evaluating Recoverable
  Reserves and Potential Liabilities.

     Our recent growth is due in part to acquisitions of exploration and
production companies and producing properties. We expect acquisitions will also
contribute to our future growth. Successful acquisitions require an assessment
of a number of factors, many of which are beyond our control. These factors
include recoverable reserves, exploration potential, future oil and gas prices,
operating costs and potential environmental and other liabilities. Such
assessments are inexact and their accuracy is inherently uncertain. In
connection with our assessments, we perform a review of the acquired properties,
which we believe is generally consistent with industry practices. However, such
a review will not reveal all existing or potential problems. In addition, our
review may not permit us to become sufficiently familiar with the properties to
fully assess their deficiencies and capabilities. We do not inspect every well.
Even when we inspect a well, we do not always discover structural, subsurface
and environmental problems that may exist or arise.

     We are generally not entitled to contractual indemnification for preclosing
liabilities, including environmental liabilities. Normally, we acquire interests
in properties on an "as is" basis with limited remedies for breaches of
representations and warranties. In addition, competition for producing oil and
gas properties is intense and many of our competitors have financial and other
resources which are substantially greater than those available to us. Therefore,
we cannot assure you that we will be able to acquire oil and gas properties that
contain economically recoverable reserves or that we will complete such
acquisitions on acceptable terms.

     Additionally, significant acquisitions can change the nature of our
operations and business depending upon the character of the acquired properties,
which may have substantially different operating and geological characteristics
or be in different geographic locations than our existing properties. While it
is our current intention to continue to concentrate on acquiring properties with
development and exploration potential located in the Mid-Continent region, there
can be no assurance that in the future we will not decide to pursue acquisitions
or properties located in other geographic regions. To the extent that such
acquired properties are substantially different than our existing properties,
our ability to efficiently realize the economic benefits of such transactions
may be limited.

  Oil and Gas Drilling and Producing Operations Are Hazardous and Expose Us to
  Environmental Liabilities.

     Oil and gas operations are subject to many risks, including well blowouts,
cratering and explosions, pipe failure, fires, formations with abnormal
pressures, uncontrollable flows of oil, natural gas, brine or well fluids, and
other environmental hazards and risks. Our drilling operations involve risks
from high pressures and from mechanical difficulties such as stuck pipes,
collapsed casings and separated cables. If any of these risks occurs, we could
sustain substantial losses as a result of:

     - injury or loss of life;

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

     - pollution or other environmental damage;

     - clean-up responsibilities;

     - regulatory investigations and penalties; and

     - suspension of operations.

     Our liability for environmental hazards includes those created either by
the previous owners of properties that we purchase or lease or by acquired
companies prior to the date we acquire them. In accordance with industry
practice, we maintain insurance against some, but not all, of the risks
described above. We cannot assure you that our insurance will be adequate to
cover casualty losses or liabilities. Also, we cannot predict the continued
availability of insurance at premium levels that justify its purchase.

  Exploration and Development Drilling May Not Result in Commercially Productive
  Reserves.

     We do not always encounter commercially productive reservoirs through our
drilling operations. We cannot assure you that the new wells we drill or
participate in will be productive or that we will recover all or any portion of
our investment in wells drilled. The seismic data and other technologies we use
do not allow us to know conclusively prior to drilling a well that oil or gas is
present or may be produced economically. The cost of drilling, completing and
operating a well is often uncertain, and cost factors can adversely affect the
economics of a project. Our efforts will be unprofitable if we drill dry wells
or wells that are productive but do not produce enough reserves to return a
profit after drilling, operating and other costs. Further, our drilling
operations may be curtailed, delayed or canceled as a result of a variety of
factors, including:

     - unexpected drilling conditions;

     - title problems;

     - pressure or irregularities in formations;

     - equipment failures or accidents;

     - adverse weather conditions;

     - compliance with environmental and other governmental requirements; and

     - cost of, or shortages or delays in the availability of, drilling rigs and
       equipment.

  Canadian Operations Present the Risks Associated with Conducting Business
  Outside the United States.

     Our operations in Canada are subject to the risks associated with operating
outside of the United States. These risks include the following:

     - adverse local political or economic developments;

     - exchange controls;

     - currency fluctuations;

     - royalty and tax increases;

     - retroactive tax claims;

     - negotiations of contracts with governmental entities; and

     - import and export regulations.

     In addition, in the event of a dispute, we may be required to litigate the
dispute in Canadian courts since we may not be able to sue foreign persons in a
U.S. court.

  The Loss of Key Personnel Could Adversely Affect Our Ability to Operate.

     We depend, and will continue to depend in the foreseeable future, on the
services of our officers and key employees with extensive experience and
expertise in evaluating and analyzing producing oil and gas properties and
drilling prospects, maximizing production from oil and gas properties and
marketing oil and gas production. Our ability to retain our officers and key
employees is important to our continued success and growth. The unexpected loss
of the services of one or more of these individuals could have a detrimental
effect on our business. We have maintained $20 million key man life insurance
policies on each of our chief executive officer and chief operating officer but
do not intend to renew these policies when they expire on June 1, 2001.

                                        11

  Transactions with Executive Officers May Create Conflicts of Interest.

     Our chief executive officer and chief operating officer, Aubrey K.
McClendon and Tom L. Ward, have the right to participate in wells we drill,
subject to limitations in their employment contract. As a result of their
participation, they routinely have significant accounts payable to us for joint
interest billings and other related advances. As of March 31, 2001, Messrs.
McClendon and Ward had payables to us of $3.4 million and $3.2 million,
respectively, in connection with such participation.

RISKS RELATED TO THE EXCHANGE OFFER AND THE NEW NOTES

  If You Do Not Properly Tender Your Outstanding 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 outstanding notes that you
timely and properly tender. Therefore, you should allow sufficient time to
endure timely delivery of the outstanding notes and you should carefully follow
the instructions on how to tender your outstanding notes. Neither we nor the
exchange agent is required to tell you of any defects or irregularities with
respect to your tender of outstanding notes.

     If you do not exchange your outstanding notes for new notes pursuant to the
exchange offer, the outstanding notes you hold will continue to be subject to
the existing transfer restrictions. In general, you may not offer or sell the
outstanding notes except under an exemption from, or in a transaction not
subject to, the Securities Act of 1933 and applicable state securities laws. We
do not plan to register outstanding notes under the Securities Act of 1933
unless our registration rights agreement with the initial purchasers of the
outstanding notes requires us to do so. Further, if you continue to hold any
outstanding notes after the exchange offer is consummated, you may have trouble
selling them because there will be fewer outstanding notes outstanding.

  If an Active Trading Market Does Not Develop for the New Notes, You May Be
  Unable to Sell the New Notes or to Sell the New Notes at a Price That You Deem
  Sufficient.

     The new notes will be new securities for which there currently is no
established trading market. Although we will register the new notes under the
Securities Act of 1933, we do not intend to apply for listing of the new notes
on any securities exchange or for quotation of the new notes in any automated
dealer quotation system. In addition, although the initial purchasers of the
outstanding notes have informed us that they intend to make a market in the new
notes after the exchange offer, the initial purchasers may stop making a market
at any time. Finally, if a large number of holders of outstanding notes do not
tender outstanding notes or tender outstanding notes improperly, the limited
amount of new notes that would be issued and outstanding after we consummate the
exchange offer could adversely affect the development of a market for these new
notes.

  A Guarantee Could Be Voided if the Guarantor Fraudulently Transferred the
  Guarantee at the Time it Incurred the Indebtedness, which Could Result in the
  Noteholders Being Able to Rely on Only Chesapeake Energy Corporation to
  Satisfy Claims.

     Under U.S. bankruptcy law and comparable provisions of state fraudulent
transfer laws, a guarantee can be voided, or claims under a 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:

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

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

                                        12
   15

     - 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.

     In addition, any payment by that guarantor under a guarantee could be
voided and required to be returned to the guarantor or to a fund for the benefit
of the creditors of the 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 of its assets;

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

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

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

  Holders of the New Notes Will Be Effectively Subordinated to All of Our and
  the Subsidiary Guarantors' Secured Indebtedness and to All Liabilities of Our
  Non-Guarantor Subsidiaries.

     Holders of our secured indebtedness, including the indebtedness under our
credit facilities, have claims with respect to our assets constituting
collateral for their indebtedness that are prior to your claims under the new
notes. In the event of a default on the new notes or our bankruptcy, liquidation
or reorganization, those assets would be available to satisfy obligations with
respect to the indebtedness secured thereby before any payment could be made on
the new notes. Accordingly, the secured indebtedness would effectively be senior
to the new notes to the extent of the value of the collateral securing the
indebtedness. While the indenture governing the new notes places some
limitations on our ability to create liens, there are significant exceptions to
these limitations, including with respect to sale and leaseback transactions,
that will allow us to secure some kinds of indebtedness without equally and
ratably securing the new notes. To the extent the value of the collateral is not
sufficient to satisfy the secured indebtedness, the holders of that indebtedness
would be entitled to share with the holders of the new notes and the holders of
other claims against us with respect to our other assets.

     In addition, the new notes are not guaranteed by all of our subsidiaries,
and our non-guarantor subsidiaries are permitted to incur additional
indebtedness under the indenture. As a result, holders of the new notes will be
effectively subordinated to claims of third party creditors, including holders
of indebtedness, and preferred shareholders of these non-guarantor subsidiaries.
Claims of those other creditors, including trade creditors, secured creditors,
authorities, holders of indebtedness or guarantees issued by the non-guarantor
subsidiaries and preferred shareholders of the non-guarantor subsidiaries, will
generally have priority as to the assets of the non-guarantor subsidiaries over
our claims and equity interests. As a result, holders of our indebtedness,
including the holders of the new notes, will be effectively subordinated to all
those claims.

                                 EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     In connection with the issuance of the outstanding notes, we entered into a
registration rights agreement. Under the registration rights agreement, we
agreed to:

     - within 60 days after the original issuance of the outstanding notes, file
       a registration statement with the SEC with respect to a registered offer
       to exchange each outstanding note for a new note having terms
       substantially identical in all material respects to such note except that
       the new note will not contain terms with respect to transfer
       restrictions);

     - use our best efforts to cause the registration statement to be declared
       effective under the Securities Act of 1933 within 180 days after the
       original issuance of the outstanding notes;

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

     - keep the exchange offer open for not less than 20 business days (or
       longer if required by applicable law) after the date notice of the
       exchange offer is mailed to the holders of the outstanding notes.

     We have fulfilled the agreements described in the first two of the
preceding bullet points, and as soon as practicable after this registration
statement becomes effective, we will offer eligible holders of the outstanding
notes the opportunity to exchange their outstanding notes for new notes
registered under the Securities Act. Holders are eligible if they are not
prohibited by any law or policy of the SEC from participating in this exchange
offer. The new notes will be substantially identical to the outstanding notes
except that the new notes will not contain terms with respect to transfer
restrictions, registration rights or additional interest.

     Under limited circumstances, we agreed to use our best efforts to cause the
SEC to declare effective a shelf registration statement for the resale of the
outstanding notes. We also agreed to use our best efforts to keep the shelf
registration statement effective for up to two years after its effective date.
The circumstances include if:

     - applicable interpretations of the staff of the SEC do not permit us to
       effect the exchange offer; or

     - for any other reason the exchange offer is not consummated within 240
       days from April 6, 2001, the date of the original issuance of the
       outstanding notes; or

     - any of the initial purchasers notifies us following consummation of the
       exchange offer that outstanding notes held by it are not eligible to be
       exchanged for exchange notes in the exchange offer; or

     - certain holders are prohibited by law or SEC policy from participating in
       the exchange offer or may not resell the new notes acquired by them in
       the exchange offer to the public without delivering a prospectus and this
       prospectus is not available for such resales.

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

     - if the exchange offer is not consummated on or before the 60th business
       day after this registration statement is declared effective,

     - if obligated to file a shelf registration statement, we fail to file the
       shelf registration statement with the SEC on or prior to the 30th day
       after the date on which the obligation to file a shelf registration
       statement arises, or shelf filing date,

     - if obligated to file a shelf registration statement, the shelf
       registration statement is not declared effective on or prior to the 180th
       day after the shelf filing date, or

                                        14
   17

     - after this 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 being a
       "registration default");

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

     The rate of the additional interest will be 0.5% per year for the first
90-day period immediately following the occurrence of a registration default,
and such rate will increase by an additional 0.5% 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 2.0% per year. We 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
outstanding notes and the new notes.

     Upon the effectiveness of this registration statement, the consummation of
the exchange offer, the effectiveness of a shelf registration statement, or the
effectiveness of a succeeding registration statement, as the case may be, the
interest rate borne by the notes from the date of such effectiveness or
consummation, as the case may be, will be reduced to the original interest rate.
However, if after any such reduction in interest rate, a different event
specified in the clauses above occurs, the interest rate may again be increased
pursuant to the preceding provisions.

     To exchange your outstanding notes for transferable new notes in the
exchange offer, you will be required to make the following representations:

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

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

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

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

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

     In addition, we may require you to provide information to be used in
connection with the shelf registration statement to have your outstanding notes
included in the shelf registration statement and benefit from the provisions
regarding additional interest described in the preceding paragraphs. A holder
who sells outstanding notes under the shelf registration statement generally
will be required to be named as a selling securityholder in the related
prospectus and to deliver a prospectus to purchasers. Such a holder will also be
subject to 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 a holder, including indemnification
obligations.

     The description of the registration rights agreement contained in this
section is a summary only. For more information, you should review the
provisions of the registration rights agreement that we filed with the SEC as an
exhibit to the registration statement of which this prospectus is a part.

RESALE OF NEW NOTES

     Based on no action letters of the SEC staff issued to third parties, we
believe that new notes may be offered for resale, resold and otherwise
transferred by you without further compliance with the registration and
prospectus delivery provisions of the Securities Act if:

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

     - such new notes are acquired in the ordinary course of your business; and

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

     The SEC, however, has not considered the exchange offer for the new notes
in the context of a no action letter, and the SEC may not make a similar
determination as in the no action letters issued to these third parties.

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

     - cannot rely on such interpretations by the SEC staff; and

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

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

TERMS OF THE EXCHANGE OFFER

     Subject to the terms and conditions described in this prospectus and in the
letter of transmittal, we will accept for exchange any outstanding notes
properly tendered and not withdrawn prior to 5:00 p.m. New York City time on the
expiration date. We will issue new notes in principal amount equal to the
principal amount of outstanding notes surrendered under the exchange offer.
Outstanding notes may be tendered only for new notes and only in integral
multiples of $1,000.

     The exchange offer is not conditioned upon any minimum aggregate principal
amount of outstanding notes being tendered for exchange.

     As of the date of this prospectus, $800,000,000 in aggregate principal
amount of the outstanding notes are outstanding. This prospectus and the letter
of transmittal are being sent to all registered holders of outstanding notes.
There will be no fixed record date for determining registered holders of
outstanding notes entitled to participate in the exchange offer.

     We intend to conduct the exchange offer in accordance with the provisions
of the registration rights agreement, the applicable requirements of the
Securities Act and the Securities Exchange Act of 1934 and the rules and
regulations of the SEC. Outstanding notes that the holders thereof do not tender
for exchange in the exchange offer will remain outstanding and continue to
accrue interest. These outstanding notes will be entitled to the rights and
benefits such holders have under the indenture relating to the notes and the
registration rights agreement.

                                        16
   19

     We will be deemed to have accepted for exchange properly tendered
outstanding notes when we have given oral or written notice of the acceptance to
the exchange agent and complied with the applicable provisions of the
registration rights agreement. The exchange agent will act as agent for the
tendering holders for the purposes of receiving the new notes from us.

     If you tender outstanding notes in the exchange offer, you will not be
required to pay brokerage commissions or fees or, subject to the letter of
transmittal, transfer taxes with respect to the exchange of outstanding notes.
We will pay all charges and expenses, other than certain applicable taxes
described below, in connecting with the exchange offer. It is important that you
read the section labeled "-- Fees and Expenses" for more details regarding fees
and expenses incurred in the exchange offer.

     We will return any outstanding notes that we do not accept for exchange for
any reason without expense to their tendering holder as promptly as practicable
after the expiration or termination of the exchange offer.

EXPIRATION DATE

     The exchange offer will expire at 5:00 p.m. New York City time on July 12,
2001, unless, in our sole discretion, we extend it.

EXTENSIONS, DELAYS IN ACCEPTANCE, TERMINATION OR AMENDMENT

     We expressly reserve the right, at any time or various times, to extend the
period of time during which the exchange offer is open. We may delay acceptance
of any outstanding notes by giving oral or written notice of such extension to
their holders. During any such extensions, all outstanding notes previously
tendered will remain subject to the exchange offer, and we may accept them for
exchange.

     In order to extend the exchange offer, we will notify the exchange agent
orally or in writing of any extension. We will notify the registered holders of
outstanding notes of the extension no later than 9:00 a.m., New York City time,
on the business day after the previously scheduled expiration date.

     If any of the conditions described below under "-- Conditions to the
Exchange Offer" have not been satisfied, we reserve the right, in our sole
discretion

     - to delay accepting for exchange any outstanding notes,

     - to extend the exchange offer, or

     - to terminate the exchange offer,

by giving oral or written notice of such delay, extension or termination to the
exchange agent. Subject to the terms of the registration rights agreement, we
also reserve the right to amend the terms of the exchange offer in any manner.

     Any such delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice thereof to the
registered holders of outstanding notes. If we amend the exchange offer in a
manner that we determine to constitute a material change, we will promptly
disclose such amendment by means of a prospectus supplement. The supplement will
be distributed to the registered holders of the outstanding notes. Depending
upon the significance of the amendment and the manner of disclosure to the
registered holders, we will extend the exchange offer if the exchange offer
would otherwise expire during such period.

CONDITIONS TO THE EXCHANGE OFFER

     We will not be required to accept for exchange, or exchange any new notes
for, any outstanding notes if the exchange offer, or the making of any exchange
by a holder of outstanding notes, would violate applicable law or any applicable
interpretation of the staff of the SEC. Similarly, we may terminate the

                                        17
   20

exchange offer as provided in this prospectus before accepting outstanding notes
for exchange in the event of such a potential violation.

     In addition, we will not be obligated to accept for exchange the
outstanding notes of any holder that has not made to us the representations
described under "-- Purpose and Effect of the Exchange Offer," "-- Procedures
for Tendering" and "Plan of Distribution" and such other representations as may
be reasonably necessary under applicable SEC rules, regulations or
interpretations to allow us to use an appropriate form to register the new notes
under the Securities Act.

     We expressly reserve the right to amend or terminate the exchange offer,
and to reject for exchange any outstanding notes not previously accepted for
exchange, upon the occurrence of any of the conditions to the exchange offer
specified above. We will give oral or written notice of any extension,
amendment, non-acceptance or termination to the holders of the outstanding notes
as promptly as practicable.

     These conditions are for our sole benefit, and we may assert them or waive
them in whole or in part at any time or at various times in our sole discretion.
If we fail at any time to exercise any of these rights, this failure will not
mean that we have waived our rights. Each such right will be deemed an ongoing
right that we may assert at any time or at various times.

     In addition, we will not accept for exchange any outstanding notes
tendered, and will not issue new notes in exchange for any such outstanding
notes, if at such time any stop order has been threatened or is in effect with
respect to the registration statement of which this prospectus constitutes a
part or the qualification of the indenture relating to the notes under the Trust
Indenture Act of 1939.

PROCEDURES FOR TENDERING

  How to Tender Generally

     Only a holder of outstanding notes may tender such outstanding notes in the
exchange offer. To tender in the exchange offer, a holder must:

     - complete, sign and date the letter of transmittal, or a facsimile of the
       letter of transmittal;

     - have the signature on the letter of transmittal guaranteed if the letter
       of transmittal so requires; and

      - mail or deliver such letter of transmittal or facsimile to the exchange
        agent prior to 5:00 p.m. New York City time on the expiration date; or

      - comply with the automated tender offer program procedures of The
        Depository Trust Company, or DTC, described below.

     In addition, either:

     - the exchange agent must receive outstanding notes along with the letter
       of transmittal;

     - the exchange agent must receive, prior to 5:00 p.m. New York City time on
       the expiration date, a timely confirmation of book-entry transfer of such
       outstanding notes into the exchange agent's account at DTC according to
       the procedure for book-entry transfer described below or a properly
       transmitted agent's message; or

     - the holder must comply with the guaranteed delivery procedures described
       below.

     To be tendered effectively, the exchange agent must receive any physical
delivery of the letter of transmittal and other required documents at its
address indicated on the cover page of the letter of transmittal. The exchange
agent must receive such documents prior to 5:00 p.m. New York City time on the
expiration date.

     The tender by a holder that is not withdrawn prior to 5:00 p.m. New York
City time on the expiration date will constitute an agreement between the holder
and us in accordance with the terms and subject to the conditions described in
this prospectus and in the letter of transmittal.

                                        18
   21

     THE METHOD OF DELIVERY OF OUTSTANDING NOTES, THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT YOUR ELECTION AND RISK.
RATHER THAN MAIL THESE ITEMS, WE RECOMMEND THAT YOU USE AN OVERNIGHT OR HAND
DELIVERY SERVICE. IN ALL CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO ASSURE
DELIVERY TO THE EXCHANGE AGENT BEFORE 5:00 P.M. NEW YORK CITY TIME ON THE
EXPIRATION DATE. YOU SHOULD NOT SEND THE LETTER OF TRANSMITTAL OR OUTSTANDING
NOTES TO US. YOU MAY REQUEST YOUR BROKERS, DEALERS, COMMERCIAL BANKS, TRUST
COMPANIES OR OTHER NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR YOU.

  How to Tender if You Are a Beneficial Owner

     If you beneficially own outstanding notes that are registered in the name
of a broker, dealer, commercial bank, trust company or other nominee and you
wish to tender those notes, you should contact the registered holder promptly
and instruct it to tender on your behalf. If you are a beneficial owner and wish
to tender on your own behalf, you must, prior to completing and executing the
letter of transmittal and delivering your outstanding notes, either:

     - make appropriate arrangements to register ownership of the outstanding
       notes in your name; or

     - obtain a properly completed bond power from the registered holder of
       outstanding notes.

     The transfer of registered ownership, if permitted under the indenture for
the notes, may take considerable time and may not be completed prior to the
expiration date.

  Signatures and Signature Guarantees

     You must have signatures on a letter of transmittal or a notice of
withdrawal (as described below) guaranteed by a member firm of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States, or an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Securities Exchange Act. In
addition, such entity must be a member of one of the recognized signature
guarantee programs identified in the letter of transmittal. Signature guarantees
are not required, however, if the notes are tendered:

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

     - for the account of a member firm of a registered national securities
       exchange or of the National Association of Securities Dealers, Inc., a
       commercial bank or trust company having an office or correspondence in
       the United States, or an eligible guarantor institution.

  When You Need Endorsements or Bond Powers

     If the letter of transmittal is signed by a person other than the
registered holder of any outstanding notes, the outstanding notes must be
endorsed or accompanied by a properly completed bond power. The bond power must
be signed by the registered holder as the registered holder's name appears on
the outstanding notes. A member firm of a registered national securities
exchange or of the National Association of Securities Dealers, Inc., a
commercial bank or trust company having an office or correspondent in the United
States, or an eligible guarantor institution must guarantee the signature on the
bond power.

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

  Tendering Through DTC's Automated Tender Offer Program

     The exchange agent and DTC have confirmed that any financial institution
that is a participant in DTC's system may use DTC's automated tender offer
program to tender. Participants in the program may, instead of physically
completing and signing the letter of transmittal and delivering it to the
exchange agent, transmit their acceptance of the exchange offer electronically.
They may do so by causing DTC to transfer the outstanding notes to the exchange
agent in accordance with its procedures for transfer. DTC will then send an
agent's message to the exchange agent.

     The term "agent's message" means a message transmitted by DTC, received by
the exchange agent and forming part of the book-entry confirmation, to the
effect that:

     - DTC has received an express acknowledgment from a participant in its
       automated tender offer program that is tendering outstanding notes that
       are the subject of such book-entry confirmation;

     - such participant has received and agrees to be bound by the terms of the
       letter of transmittal or, in the case of an agent's message relating to
       guaranteed delivery, that such participant has received and agrees to be
       bound by the applicable notice of guaranteed delivery; and

     - the agreement may be enforced against such participant.

  Determinations Under the Exchange Offer

     We will determine in our sole discretion all questions as to the validity,
form, eligibility, time of receipt, acceptance of tendered outstanding notes and
withdrawal of tendered outstanding notes. Our determination will be final and
binding. We reserve the absolute right to reject any outstanding notes not
properly tendered or any outstanding notes our acceptance of which would, in the
opinion of our counsel, be unlawful. We also reserve the right to waive any
defect, irregularities or conditions of tender as to particular outstanding
notes. Our interpretation of the terms and conditions of the exchange offer,
including the instructions in the letter of transmittal, will be final and
binding on all parties. Unless waived, all defects or irregularities in
connection with tenders of outstanding notes must be cured within such time as
we shall determine. Although we intend to notify holders of defects or
irregularities with respect to tenders of outstanding notes, neither we, the
exchange agent nor any other person will incur any liability for failure to give
such notification. Tenders of outstanding notes will not be deemed made until
such defects or irregularities have been cured or waived. Any outstanding notes
received by the exchange agent that are not properly tendered and as to which
the defects or irregularities have not been cured or waived will be returned to
the tendering holder, unless otherwise provided in the letter of transmittal, as
soon as practicable following the expiration date.

  When We Will Issue New Notes

     In all cases, we will issue new notes for outstanding notes that we have
accepted for exchange under the exchange offer only after the exchange agent
timely receives:

     - outstanding notes or a timely book-entry confirmation of such outstanding
       notes into the exchange agent's account at DTC; and

     - a properly completed and duly executed letter of transmittal and all
       other required documents or a properly transmitted agent's message.

  Return of Outstanding Notes Not Accepted or Exchanged

     If we do not accept any tendered outstanding notes for exchange or if
outstanding notes are submitted for a greater principal amount than the holder
desires to exchange, the unaccepted or non-exchanged outstanding notes will be
returned without expense to their tendering holder. In the case of outstanding
notes tendered by book-entry transfer in the exchange agent's account at DTC
according to the procedures described below, such non-exchanged outstanding
notes will be credited to an account maintained with

                                        20
   23

DTC. These actions will occur as promptly as practicable after the expiration or
termination of the exchange offer.

  Your Representations to Us

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

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

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

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

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

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

BOOK-ENTRY TRANSFER

     The exchange agent will establish an account with respect to the
outstanding notes at DTC for purposes of the exchange offer promptly after the
date of this prospectus. Any financial institution participating in DTC's system
may make book-entry delivery of outstanding notes by causing DTC to transfer
such outstanding notes into the exchange agent's account at DTC in accordance
with DTC's procedures for transfer. Holders of outstanding notes who are unable
to deliver confirmation of the book-entry tender of their outstanding notes into
the exchange agent's account at DTC or all other documents required by the
letter of transmittal to the exchange agent on or prior to 5:00 p.m. New York
City time on the expiration date must tender their outstanding notes according
to the guaranteed delivery procedures described below.

GUARANTEED DELIVERY PROCEDURES

     If you wish to tender your outstanding notes but your outstanding notes are
not immediately available or you cannot deliver your outstanding notes, the
letter of transmittal or any other required documents to the exchange agent or
comply with the applicable procedures under DTC's automated tender offer program
prior to the expiration date, you may tender if:

     - the tender is made through a member firm of a registered national
       securities exchange or of the National Association of Securities Dealers,
       Inc., a commercial bank or trust company having an office or
       correspondent in the United States, or an eligible guarantor institution,

     - prior to the expiration date, the exchange agent receives from such
       member firm of a registered national securities exchange or of the
       National Association of Securities Dealers, Inc., commercial bank or
       trust company having a office or correspondent in the United States, or
       eligible guarantor institution either a properly completed and duly
       executed notice of guaranteed delivery by facsimile transmission, mail or
       hand delivery or a properly transmitted agent's message and notice of
       guaranteed delivery:

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

      - stating that the tender is being made thereby, and

      - guaranteeing that, within three (3) New York Stock Exchange ("NYSE")
        trading days after the expiration date, the letter of transmittal or
        facsimile thereof, together with the outstanding notes

                                        21
   24

        or a book-entry confirmation, and any other documents required by the
        letter of transmittal will be deposited by the eligible guarantor
        institution with the exchange agent, and

     - the exchange agent receives such properly completed and executed letter
       of transmittal or facsimile thereof, as well as all tendered outstanding
       notes in proper form for transfer or a book-entry confirmation, and all
       other documents required by the letter of transmittal, within three (3)
       NYSE trading days after the expiration date.

     Upon request to the exchange agent, a notice of guaranteed delivery will be
sent you if you wish to tender your outstanding notes according to the
guaranteed delivery procedures described above.

WITHDRAWAL OF TENDERS

     Except as otherwise provided in this prospectus, you may withdraw your
tender at any time prior to 5:00 p.m. New York City time on the expiration date.

     For a withdrawal to be effective:

     - the exchange agent must receive a written notice of withdrawal at the
       address indicated on the cover page of the letter of transmittal or

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

     Any notice of withdrawal must:

     - specify the name of the person who tendered the outstanding notes to be
       withdrawn, and

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

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

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

     Any outstanding notes that have been tendered for exchange but that are not
exchanged for any reason will be returned to their holder without cost to the
holder. In the case of outstanding notes tendered by book-entry transfer into
the exchange agent's account at DTC according to the procedures described above,
such outstanding notes will be credited to an account maintained with DTC for
the outstanding notes. This return or crediting will take place as soon as
practicable after withdrawal, rejection of tender or termination of the exchange
offer. You may retender properly withdrawn outstanding notes by following one of
the procedures described under "-- Procedures for Tendering" above at any time
on or prior to the expiration date.

FEES AND EXPENSES

     We will bear the expenses of soliciting tenders. The principal solicitation
is being made by mail; however, we may make additional solicitation by
telegraph, telephone or in person by our officers and regular employees and
those of our affiliates.

     We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to broker-dealers or others soliciting
acceptances of the exchange offer. We will, however, pay the exchange agent
reasonable and customary fees for its services and reimburse it for its related
reasonable out-of-pocket expenses.

                                        22
   25

     We will pay the cash expenses to be incurred in connection with the
exchange offer. They include:

     - SEC registration fees;

     - fees and expenses of the exchange agent and trustee;

     - accounting and legal fees and printing costs; and

     - related fees and expenses.

TRANSFER TAXES

     We will pay all transfer taxes, if any, applicable to the exchange of
outstanding 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:

     - certificates representing outstanding notes for principal amounts not
       tendered or accepted for exchange are to be delivered to, or are to be
       issued in the name of, any person other than the registered holder of
       outstanding notes tendered;

     - tendered outstanding notes are registered in the name of any person other
       than the person signing the letter of transmittal; or

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

     If satisfactory evidence of payment of any transfer taxes payable by a note
holder is not submitted with the letter of transmittal, the amount of such
transfer taxes will be billed directly to that tendering holder.

CONSEQUENCES OF FAILURE TO EXCHANGE

     If you do not exchange new notes for your outstanding notes under the
exchange offer, you will remain subject to the existing restrictions on transfer
of the outstanding notes. In general, you may not offer or sell the outstanding
notes unless they are registered under the Securities Act, or if the offer or
sale is exempt from the registration under the Securities Act and applicable
state securities laws. Except as required by the registration rights agreement,
we do not intend to register resales of the outstanding notes under the
Securities Act.

ACCOUNTING TREATMENT

     We will record the new notes in our accounting records at the same carrying
value as the outstanding notes. This carrying value is the aggregate principal
amount of the outstanding notes less any bond discount, as reflected in our
accounting records on the date of exchange. Accordingly, we will not recognize
any gain or loss for accounting purposes in connection with the exchange offer.

OTHER

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

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

                      RATIOS OF EARNINGS TO FIXED CHARGES

     For purposes of determining the ratio of earnings to fixed charges,
earnings are defined as net income (loss) before income taxes, extraordinary
items, amortization of capitalized interest and fixed charges, less capitalized
interest. Fixed charges consist of interest (whether expensed or capitalized),
and amortization of debt expenses and discount or premium relating to any
indebtedness.

                                USE OF PROCEEDS

     The exchange offer is intended to satisfy our obligations under the
registration rights agreement. We will not receive any cash proceeds from the
issuance of the new notes in the exchange offer. In consideration for issuing
the new notes as contemplated by this prospectus, we will receive outstanding
notes in a like principal amount. The form and terms of the new notes are
identical in all respects to the form and terms of the outstanding notes, except
the new notes do not include certain transfer restrictions. Outstanding notes
surrendered in exchange for the new notes will be retired and cancelled and will
not be reissued. Accordingly, the issuance of the new notes will not result in
any change in our outstanding indebtedness.

                                    BUSINESS

     We are among the ten largest independent natural gas producers in the
United States, owning interests in approximately 6,700 producing oil and gas
wells with approximately 1.7 tcfe of proved reserves, of which 91% are natural
gas. Our primary operating area is the Mid-Continent region of the United
States, which includes Oklahoma, western Arkansas, southwestern Kansas and the
Texas Panhandle. Other core operating areas include: the Deep Giddings field in
Texas, which includes the Austin Chalk and Georgetown formations; the Helmet
area of northeastern British Columbia; and the Permian Basin region of
southeastern New Mexico.

     Additional information concerning the Company is included in the Company
reports and other documents incorporated by reference in this prospectus. See
"Where You Can Find More Information."

                          DESCRIPTION OF THE NEW NOTES

     The new notes will be issued, and the outstanding notes were issued,
pursuant to an indenture dated as of April 6, 2001 (the "Indenture") among the
Company, as issuer, the Restricted Subsidiaries, as guarantors, and United
States Trust Company of New York, as trustee (the "Trustee"). The terms of the
new notes include those stated in the Indenture and those made part of the
Indenture by the Trust Indenture Act of 1939, as amended (the "Trust Indenture
Act"). The definitions of certain capitalized terms used in the following
summary are set forth below under "-- Certain Definitions." References to the
"notes" in this section of the prospectus include both the outstanding notes and
the new notes.

     The following description is a summary of the material provisions of the
Indenture. It does not restate that agreement in its entirety. The Company urges
Holders to read the Indenture because it, and not this description, defines the
rights of Holders of these notes. The Company has filed the Indenture as an
exhibit to the registration statement which includes this prospectus.

     If the exchange offer contemplated by this prospectus (the "Exchange
Offer") is consummated, Holders of outstanding notes who do not exchange those
notes for new notes in the Exchange Offer will vote together with Holders of new
notes for all relevant purposes under the Indenture. In that regard, the
Indenture requires that certain actions by the Holders thereunder (including
acceleration following an Event of Default) must be taken, and certain rights
must be exercised, by specified minimum percentages of the aggregate principal
amount of the outstanding securities issued under the Indenture. In determining
whether Holders of the requisite percentage in principal amount have given any
notice, consent or waiver or taken any other action permitted under the
Indenture, any outstanding notes that remain outstanding after the Exchange
Offer will be aggregated with the new notes, and the Holders of such outstanding
notes and the new notes will vote together as a single series for all such
purposes. Accordingly, all references herein to specified percentages in
aggregate principal amount of the notes outstanding shall be deemed to mean, at
any time after the Exchange Offer is consummated, such percentages in aggregate
principal amount of the outstanding notes and the new notes then outstanding.

BRIEF DESCRIPTION OF THE NOTES

     The notes:

     - are unsecured senior indebtedness of the Company;

     - are limited to $1,000,000,000 in aggregate principal amount, of which
       $800,000,000 are outstanding;

     - are senior in right of payment to all future Subordinated Indebtedness of
       the Company; and

     - rank equally in right of payment with all existing and future Senior
       Indebtedness.

     The new notes will be issued, and the outstanding notes were issued, only
in registered form, without coupons, in denominations of $1,000 and integral
multiples thereof.

     Any outstanding notes that remain outstanding after the completion of the
Exchange Offer, together with the new notes issued in connection with the
Exchange Offer, will be treated as a single class of securities under the
Indenture.

     The Company may issue the notes from time to time with a maximum aggregate
principal amount of $1 billion, of which $800 million were issued on April 6,
2001. Any notes originally issued after the date of original issuance of the
outstanding notes (the "Add On Notes") will be subject to the debt incurrence
covenant described in the first paragraph of "-- Certain
Covenants -- Limitations on Incurrence of Additional Indebtedness." Any Add On
Notes that are actually issued will be treated as issued and outstanding notes
(as the same class as the notes) for all purposes of the Indenture and this
"Description of the New Notes," unless the context indicates otherwise.

     Each note will mature on April 1, 2011 and will bear interest at the rate
of interest per annum indicated on the cover page of this prospectus.

                                        25

     Interest on the new notes will accrue from the date of original issuance of
the outstanding notes, April 6, 2001, and will be payable semiannually in
arrears on April 1 and October 1 of each year, commencing October 1, 2001. We
will make each interest payment to the holders of record of the notes at the
close of business on the March 15 or September 15 preceding such interest
payment date. Interest will be computed on the basis of a 360-day year of twelve
30-day months. Principal, premium, if any, and interest will be payable at the
offices of the Trustee and the Paying Agent, provided that, at the option of the
Company, payment of interest on notes not in global form may be made by check
mailed to the address of the Person entitled thereto as it appears in the
register of the notes maintained by the Registrar. Initially, the Trustee will
also act as Paying Agent and Registrar for the notes.

GUARANTEES

     The existing subsidiaries of the Company other than Chesapeake Energy
Marketing, Inc. and Carmen Acquisition Corp. will fully and unconditionally
guarantee, on a joint and several basis, the Company's obligations to pay
principal of, premium, if any, and interest on the new notes. Each Person that
becomes a Restricted Subsidiary after the date of original issuance of the
outstanding notes will guarantee the payment of the notes.

     The obligations of each Subsidiary Guarantor under its Guarantee will be
limited as necessary to prevent that Guarantee from constituting a fraudulent
conveyance or fraudulent transfer under federal, state or foreign law. Each
Subsidiary Guarantor that makes a payment or distribution under a Guarantee
shall be entitled to a contribution from each other Subsidiary Guarantor in a
pro rata amount based on the respective net assets of each Subsidiary Guarantor
at the time of such payment determined in accordance with GAAP.

     If a Guarantee were rendered voidable, it could be subordinated by a court
to all other indebtedness (including guarantees and other contingent
liabilities) of the applicable Subsidiary Guarantor, and, depending on the
amount of such indebtedness, a Subsidiary Guarantor's liability on its Guarantee
could be reduced to zero. See "Risk Factors -- A guarantee could be voided if
the guarantor fraudulently transferred the guarantee at the time it incurred the
indebtedness, which could result in the noteholders being able to rely on only
Chesapeake to satisfy claims."

     Subject to the next paragraph, no Subsidiary Guarantor may consolidate or
merge with or into (whether or not such Subsidiary Guarantor is the surviving
Person) another Person unless

          (1) the Person formed by or surviving any such consolidation or merger
     (if other than such Subsidiary Guarantor) assumes all the obligations of
     such Subsidiary Guarantor under the Indenture and the notes pursuant to a
     supplemental indenture, in a form reasonably satisfactory to the Trustee,

          (2) immediately after such transaction, no Default or Event of Default
     exists,

          (3) such Subsidiary Guarantor or the Person formed by or surviving any
     such consolidation or merger will have Consolidated Tangible Net Worth
     immediately after the transaction equal to or greater than the Consolidated
     Tangible Net Worth of such Subsidiary Guarantor immediately preceding the
     transaction, and

          (4) the Company will, at the time of such transaction after giving pro
     forma effect thereto as if such transaction had occurred at the beginning
     of the Reference Period, be permitted to incur at least $1.00 of additional
     Indebtedness (other than Permitted Indebtedness) pursuant to the
     "-- Limitation on Incurrence of Additional Indebtedness" covenant.

     The preceding does not prohibit a merger between Subsidiary Guarantors or a
merger between the Company and a Subsidiary Guarantor.

     In the event of a sale or other disposition of all or substantially all of
the assets of any Subsidiary Guarantor, or a sale or other disposition of all
the Capital Stock of such Subsidiary Guarantor, in any case whether by way of
merger, consolidation or otherwise, or a Subsidiary Guarantor otherwise ceases
to be a

                                        26
   29

Subsidiary Guarantor, then the Person acquiring the assets (in the event of a
sale or other disposition, by way of such a merger, consolidation or otherwise,
of all or substantially all of the assets of such Subsidiary Guarantor) or such
Subsidiary Guarantor (in any other event) will be released and relieved of any
obligations under its Guarantee.

RANKING

     Senior Indebtedness versus New Notes.  The Indebtedness evidenced by the
new notes and the Guarantees will be unsecured and will rank pari passu in right
of payment to all Senior Indebtedness of the Company and the Subsidiary
Guarantors, as the case may be.

     The new notes will be unsecured obligations of the Company. Secured debt
and other secured obligations of the Company (including obligations with respect
to the Bank Credit Facility) will be effectively senior to the new notes to the
extent of the value of the assets securing such debt or other obligations.

     Liabilities of Subsidiaries versus New Notes.  A substantial portion of the
Company's operations is conducted through its subsidiaries. Claims of creditors
of such subsidiaries that are not Subsidiary Guarantors, including trade
creditors and creditors holding indebtedness or guarantees issued by such
subsidiaries, and claims of preferred stockholders of such subsidiaries will
have priority with respect to the assets and earnings of such subsidiaries over
the claims of the Company's creditors, including holders of the notes.
Accordingly, the new notes will be effectively subordinated to creditors
(including trade creditors) and preferred stockholders, if any, of the Company's
subsidiaries that are not Subsidiary Guarantors. Initially, all of the Company's
subsidiaries, other than Chesapeake Energy Marketing, Inc., will be Subsidiary
Guarantors.

     Although the Indenture limits the incurrence of Indebtedness (including
preferred stock) of the Restricted Subsidiaries, such limitations are subject to
a number of significant qualifications. In addition, the Indenture does not
impose any limitations on the incurrence by the Restricted Subsidiaries of
liabilities that are not considered Indebtedness under the Indenture. See
"-- Certain Covenants -- Limitation on Incurrence of Additional Indebtedness."
Moreover, the Indenture does not impose any limitation on the incurrence by any
Unrestricted Subsidiary of Indebtedness (including preferred stock).

OPTIONAL REDEMPTION

     At any time on or after April 1, 2006, the Company may, at its option,
redeem all or any portion of the notes at the applicable redemption prices
(expressed as percentages of the principal amount of the notes) described below,
plus, in each case, accrued but unpaid interest to the applicable redemption
date if the notes are redeemed during the twelve-month period beginning on April
1, of the years set forth below:



                                                            REDEMPTION

----                                                        ----------
                                                         
2006.....................................................    104.063%
2007.....................................................    102.708%
2008.....................................................    101.354%
2009 and thereafter......................................    100.000%


     Notwithstanding the preceding paragraph, at any time prior to April 1,
2006, the Company may, at its option, redeem all or any portion of the notes at
the Make-Whole Price plus accrued and unpaid interest to the date of redemption.
In addition, in the event the Company consummates one or more Equity Offerings
on or prior to April 1, 2004, the Company, at its option, may redeem up to
33 1/3% of the aggregate principal amount of the notes (which includes Add On
Notes, if any) issued under the Indenture with all or a portion of the aggregate
net proceeds received by the Company from such Equity Offerings at a redemption
price of 108.125%, plus accrued and unpaid interest thereon to the redemption
date; provided, however, that

                                        27
   30

     - the date of such redemption occurs within the 90-day period after the
       Equity Offering in respect of which such redemption is made and

     - following each such redemption, at least 66 2/3% of the aggregate
       principal amount of the notes (which includes Add On Notes, if any)
       issued under the Indenture remain outstanding.

CHANGE OF CONTROL

     Following the occurrence of any Change of Control, the Company must offer
to purchase all outstanding notes at a purchase price equal to 101% of the
aggregate principal amount of the notes, plus accrued and unpaid interest to the
date of purchase.

     Within 15 days after any Change of Control, the Company will mail or cause
to be mailed to all Holders on the date of the Change of Control a Notice (the
"Change of Control Notice") of the occurrence of such Change of Control and of
the Holders' rights arising as a result thereof. The Change of Control Notice
shall state, among other things:

          (1) that the change of control offer is being made pursuant to this
     covenant;

          (2) the purchase price and the change of control payment date;

          (3) that any note not tendered will continue to accrue interest;

          (4) that any note accepted for payment pursuant to the change of
     control offer shall cease to accrue interest on the change of control
     payment date; and

          (5) the instructions, consistent with the covenant described
     hereunder, that a Holder must follow in order to have such Holder's notes
     purchased.

     The change of control offer will be deemed to have commenced upon mailing
of a notice pursuant to the Indenture and will terminate 20 business days after
its commencement, unless a longer offering period is required by law. Promptly
after the termination of the change of control offer, the Company will purchase
and mail or deliver payment for all notes tendered in response to the change of
control offer.

     On the change of control payment date, the Company will, to the extent
lawful,

          (1) accept for payment notes or portions thereof 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 to the Trustee the notes so accepted together with an
     officers' certificate stating the notes or portions thereof tendered to the
     Company.

     The Paying Agent will promptly mail or deliver to each Holder of notes so
accepted payment in an amount equal to the purchase price for such notes, and
the Trustee will promptly authenticate and mail or deliver to each Holder a new
note equal in principal amount to any unpurchased portion of the notes
surrendered, if any, provided that each such new note will be in a principal
amount of $1,000 or an integral multiple thereof.

     The Company will comply with Section 14 of the Exchange Act and the
provisions of Regulation 14E and any other tender offer rules under the Exchange
Act and any other federal and state securities laws, rules and regulations which
may then be applicable to any change of control offer.

     The Change of Control purchase feature of the notes may in certain
circumstances make more difficult or discourage a sale or takeover of the
Company. The change of control purchase feature is a result of negotiations
between the Company and the initial purchasers. The Company has no present
intention to engage in a transaction involving a Change of Control, although it
is possible that it could decide to do so in the future. Subject to the
limitations discussed below, the Company could, in the future,
                                        28
   31

enter into certain transactions, including acquisitions, refinancings or other
recapitalizations, that would not constitute a Change of Control under the
Indenture, but that could increase the amount of indebtedness outstanding at
such time or otherwise affect the Company's capital structure or credit ratings.
Restrictions on the Company's ability to incur additional Indebtedness are
contained in the covenants described under "-- Certain Covenants -- Limitation
on Incurrence of Additional Indebtedness," "-- Limitation on Liens" and
"-- Limitation on Sale/Leaseback Transactions." Under the Indenture, such
restrictions can only be waived with the consent of the holders of a majority in
principal amount of the notes then outstanding. Except for the limitations
contained in such covenants, however, the Indenture will not contain any
covenants or provisions that may afford holders of the related notes protection
in the event of a highly leveraged transaction.

     Future indebtedness that the Company may incur may contain prohibitions on
the occurrence of certain events that would constitute a Change of Control or
require the repurchase of such indebtedness upon a Change of Control. Moreover,
the exercise by the Holders of their right to require 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. Finally, the Company's ability to pay cash to the Holders of notes
following the occurrence of a Change of Control may be limited by the Company's
then existing financial resources. There can be no assurance that sufficient
funds will be available when necessary to make any required repurchases.

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

CERTAIN COVENANTS

     The following restrictive covenants are applicable to the Company and its
Restricted Subsidiaries.

     Limitation on Indebtedness.  The Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, issue, incur, assume,
guarantee, become liable, contingently or otherwise, with respect to or
otherwise become responsible for the payment of (collectively, "incur") any
Indebtedness; provided, however, that if no Default or Event of Default shall
have occurred and be continuing at the time or as a consequence of the
incurrence of such Indebtedness, the Company or its Restricted Subsidiaries may
incur Indebtedness if, on a pro forma basis, after giving effect to such
incurrence and the application of the proceeds therefrom, either of the
following tests shall have been satisfied:

          (1) the Adjusted Consolidated EBITDA Coverage Ratio would have been at
     least 2.25 to 1.0; or

          (2) Adjusted Consolidated Net Tangible Assets would have been greater
     than 200% of Indebtedness of the Company and its Restricted Subsidiaries.

     Notwithstanding the preceding paragraph, if no Default or Event of Default
shall have occurred and be continuing at the time or as a consequence of the
incurrence of such Indebtedness, the Company and its Restricted Subsidiaries may
incur Permitted Indebtedness.

     Any Indebtedness of a Person existing at the time such Person becomes a
Restricted Subsidiary (whether by merger, consolidation, acquisition or
otherwise) shall be deemed to be incurred by such Restricted Subsidiary at the
time it becomes a Restricted Subsidiary.

     Limitation on Restricted Payments.  The Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, make any
Restricted Payment, unless:

          (1) no Default or Event of Default shall have occurred and be
     continuing at the time of or immediately after giving effect to such
     Restricted Payment;

          (2) at the time of and immediately after giving effect to such
     Restricted Payment, the Company would be able to incur at least $1.00 of
     additional Indebtedness (other than Permitted Indebtedness)
                                        29
   32

     pursuant to the first paragraph of the covenant captioned "-- Limitation on
     Incurrence of Additional Indebtedness"; and

          (3) immediately after giving effect to such Restricted Payment, the
     aggregate of all Restricted Payments declared or made after the Reference
     Date does not exceed the sum of:

             (a) 50% of the Consolidated Net Income of the Company and its
        Restricted Subsidiaries (or in the event such Consolidated Net Income
        shall be a deficit, minus 100% of such deficit) during the period
        (treated as one accounting period) subsequent to the Reference Date and
        ending on the last day of the fiscal quarter immediately preceding the
        date of such Restricted Payment;

             (b) the aggregate Net Cash Proceeds, and the fair market value of
        property other than cash (as determined in good faith by the Company's
        Board of Directors, including a majority of the Company's Disinterested
        Directors, and evidenced by a resolution of such Board), received by the
        Company during such period from any Person other than a Subsidiary of
        the Company as a result of the issuance or sale of Capital Stock of the
        Company (other than any Disqualified Stock and other than Preferred
        Stock issued in the Preferred Stock Offering), other than in connection
        with the conversion of Indebtedness or Disqualified Stock;

             (c) the aggregate Net Cash Proceeds, and the fair market value of
        property other than cash (as determined in good faith by the Company's
        Board of Directors, including a majority of the Company's Disinterested
        Directors, and evidenced by a resolution of such Board), received by the
        Company during such period from any Person other than a Subsidiary of
        the Company as a result of the issuance or sale of any Indebtedness or
        Disqualified Stock to the extent that at the time the determination is
        made such Indebtedness or Disqualified Stock, as the case may be, has
        been converted into or exchanged for Capital Stock of the Company (other
        than Disqualified Stock);

             (d) (1) in case any Unrestricted Subsidiary has been redesignated a
        Restricted Subsidiary, an amount equal to the lesser of (x) the book
        value (determined in accordance with GAAP) at the date of such
        redesignation of the aggregate Investments made by the Company and its
        Restricted Subsidiaries in such Unrestricted Subsidiary and (y) the fair
        market value of such Investments in such Unrestricted Subsidiary at the
        time of such redesignation (determined in good faith by the Company's
        Board of Directors, including a majority of the Company's Disinterested
        Directors, whose determination shall be conclusive and evidenced by a
        resolution of such Board); or (2) in case any Restricted Subsidiary has
        been redesignated an Unrestricted Subsidiary, minus the greater of (x)
        the book value (determined in accordance with GAAP) at the date of
        redesignation of the aggregate Investments made by the Company and its
        Restricted Subsidiaries in such Restricted Subsidiary and (y) the fair
        market value of such Investments in such Restricted Subsidiary at the
        time of such redesignation (determined in good faith by the Company's
        Board of Directors, including a majority of the Company's Disinterested
        Directors, whose determination shall be conclusive and evidenced by a
        resolution of such Board); and

             (e) $25 million.

     However, the above limitations will not prevent:

          (1) the payment of any dividend within 60 days after the date of
     declaration thereof, if at such date of declaration such payment complied
     with the provisions hereof;

          (2) the purchase, redemption, acquisition or retirement of any shares
     of Capital Stock of the Company in exchange for, or out of the net proceeds
     of the substantially concurrent sale (other than to a Restricted Subsidiary
     of the Company) of, other shares of Capital Stock (other than Disqualified
     Stock) of the Company; and

                                        30
   33

          (3) any dividend or other distribution payable from a Restricted
     Subsidiary to the Company or any other Restricted Subsidiary.

     Limitation on Sale of Assets.  The Company will not, and will not permit
any Restricted Subsidiary to, make any Asset Sale unless:

          (1) the Company (or its Restricted Subsidiaries, as the case may be)
     receives consideration at the time of such sale or other disposition at
     least equal to the fair market value thereof (as determined in good faith
     by the Company's Board of Directors and evidenced by a resolution of such
     Board, including a majority of the Company's Disinterested Directors, in
     the case of any Asset Sales or series of related Asset Sales having a fair
     market value of $20 million or greater);

          (2) at least 75% of the proceeds from such Asset Sale consist of cash,
     cash equivalents, or property, equipment, leasehold interests or other
     assets used in the Oil and Gas Business; and

          (3) the Net Available Proceeds received by the Company (or its
     Restricted Subsidiaries, as the case may be) from such Asset Sale are
     applied in accordance with the following two paragraphs.

     The Company may apply such Net Available Proceeds, within 365 days
following the receipt of Net Available Proceeds from any Asset Sale, to:

          (1) the repayment of Indebtedness of the Company under the Bank Credit
     Facility or other Senior Indebtedness, including any mandatory redemption
     or repurchase or optional redemption of the Existing Notes or the notes;

          (2) make an Investment in assets used in the Oil and Gas Business; or

          (3) develop by drilling the Company's oil and gas reserves.

     If, upon completion of the 365-day period, any portion of the Net Available
Proceeds of any Asset Sale shall not have been applied by the Company as
described in clauses (1), (2) or (3) in the immediately preceding paragraph and
such remaining Net Available Proceeds, together with any remaining net cash
proceeds from any prior Asset Sale (such aggregate constituting "Excess
Proceeds"), exceed $15 million, then the Company will be obligated to make an
offer (the "Net Proceeds Offer") to purchase the notes and any other Senior
Indebtedness in respect of which such an offer to purchase is also required to
be made concurrently with the Net Proceeds Offer having an aggregate principal
amount equal to the Excess Proceeds (such purchase to be made on a pro rata
basis if the amount available for such repurchase is less than the principal
amount of the notes and other such Senior Indebtedness tendered in such Net
Proceeds Offer) at a purchase price of 100% of the principal amount thereof plus
accrued interest to the date of repurchase. Upon the completion of the Net
Proceeds Offer, the amount of Excess Proceeds will be reset to zero.

     Any Net Proceeds Offer will be conducted in substantially the same manner
as a change of control offer. The Company will comply with Section 14 of the
Exchange Act and the provisions of Regulation 14E and any other tender offer
rules under the Exchange Act and any other federal and state securities laws,
rules and regulations which may then be applicable to any Net Proceeds Offer.

     During the period between any Asset Sale and the application of the Net
Available Proceeds therefrom in accordance with this covenant, all Net Available
Proceeds shall be maintained in a segregated account and shall be invested in
Permitted Financial Investments.

     Notwithstanding the preceding paragraph of this covenant, the Company will
not, and will not permit any Restricted Subsidiary to, directly or indirectly,
make any Asset Sale of any of the Capital Stock of a Restricted Subsidiary
except pursuant to an Asset Sale of all of the Capital Stock of such Restricted
Subsidiary.

     Limitation on Liens.  The Company will not, and will not permit any
Restricted Subsidiary to, create, incur, assume or suffer to exist any Liens
(other than Permitted Liens) upon any of their
                                        31
   34

respective properties securing any Indebtedness of the Company or any Restricted
Subsidiary, unless the notes are equally and ratably secured; provided that if
such Indebtedness is expressly subordinated to the notes or the Guarantees, the
Lien securing such Indebtedness will be subordinated and junior to the Lien
securing the notes or the Guarantees.

     Limitation on Sale/Leaseback Transactions.  The Company will not, and will
not permit any Restricted Subsidiary to, enter into any Sale/Leaseback
Transaction with any Person (other than the Company or any Wholly Owned
Restricted Subsidiary) unless:

          (a) the Company or such Restricted Subsidiary would be entitled to
     incur Indebtedness, in a principal amount equal to the Attributable
     Indebtedness with respect to such Sale/Leaseback Transaction in accordance
     with the covenant captioned "-- Limitation on Incurrence of Additional
     Indebtedness"; or

          (b) the Company or such Restricted Subsidiary receives proceeds from
     such Sale/Leaseback Transactions at least equal to the fair market value
     thereof (as determined in good faith by the Company's Board of Directors,
     whose determination in good faith, evidenced by a resolution of such Board,
     shall be conclusive) and such proceeds are applied in the same manner and
     to the same extent as Net Available Proceeds and Excess Proceeds from an
     Asset Sale.

     Limitations on Mergers and Consolidations.  The Company will not
consolidate or merge with or into any Person, or sell, convey, lease or
otherwise dispose of all or substantially all of its assets to any Person,
unless:

          (1) the Person formed by or surviving such consolidation or merger (if
     other than the Company), or to which such sale, lease, conveyance or other
     disposition or assignment shall be made (collectively, the "Successor"), is
     a corporation organized and existing under the laws of the United States or
     any state thereof or the District of Columbia, or Canada or any province
     thereof, and the Successor assumes by supplemental indenture in a form
     satisfactory to the Trustee all of the obligations of the Company under the
     Indenture and under the notes;

          (2) immediately before and after giving effect to such transaction, no
     Event of Default shall have occurred and be continuing;

          (3) immediately after giving effect to such transaction on a pro forma
     basis, the Consolidated Tangible Net Worth of the Company (or the
     Successor) is equal to or greater than the Consolidated Tangible Net Worth
     of the Company immediately before such transaction; and

(other than with a Wholly Owned Restricted Subsidiary) (an "Affiliate
Transaction"), on terms that are less favorable to the Company or such
Restricted Subsidiary, as the case may be, than would be available in a
comparable transaction with an unrelated Person. In addition, the Company will
not, and will not permit any Restricted Subsidiary of the Company to, enter into
an Affiliate Transaction, or any series of related Affiliate Transactions having
a value of:

          (a) more than $5 million, unless a majority of the Board of Directors

     prices utilized in such year-end reserve report), and decreased by, as of
     the date of determination, the discounted future net revenue of (C)
     estimated proved oil and gas reserves of the Company and its Restricted

     (D), such increases and decreases shall be as estimated by the Company's

        production included in determining the discounted future net revenue
        specified in (a)(i) above (utilizing the same prices utilized in the
        Company's year-end reserve report), would be necessary to fully satisfy
        the payment obligations of the Company and its Restricted Subsidiaries
        with respect to Dollar-Denominated Production Payments on the schedules

     Subsidiary Guarantor or any other Subsidiary (other than a Non-Recourse

     with the principal amount of any other such Indebtedness the maturity of
     which has been so accelerated, in the aggregate, or (b) such default

     grace period (a "Payment Default"), having a principal amount of $10.0
     million or more individually or, taken together with the principal amount
     of any other Indebtedness under which there has been a Payment Default, in

     in the covenants captioned "-- Limitation on Restricted Payments" and

   53

     the performance, or breach of, any other covenant or agreement of the
     Company or any Subsidiary Guarantor in the Indenture and failure to remedy
     such default within a period of 45 days after written notice thereof from
     the Trustee or Holders of 25% of the principal amount of the outstanding
     notes;

          (6) the entry by a court of one or more judgments or orders for the
     payment of money against the Company, any Subsidiary Guarantor or any other
     Subsidiary (other than a Non-Recourse Subsidiary or an Unrestricted
     Subsidiary, provided that neither the Company nor any Restricted Subsidiary

     appeal within 60 days from the entry thereof;

     of the Company or any Restricted Subsidiary of the Company.

     The Trustee may withhold notice to the Holders of the notes of any default
(except in payment of principal of, or premium, if any, or interest on the
notes) if the Trustee considers it in the interest of the Holders of the notes

of not less than 25% in principal amount of the notes outstanding may declare
the principal of and premium, if any, and accrued but unpaid interest on all the
notes to be due and payable. Upon such a declaration, such principal, premium,
if any, and interest will be due and payable immediately. If an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of the
Company or any Subsidiary of the Company occurs and is continuing, the principal
of, and premium, if any, and interest on all the notes will become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders of the notes. The amount due and payable on the
acceleration of any note will be equal to 100% of the principal amount of the
note, plus accrued and unpaid interest to the date of payment. Under certain
circumstances, the Holders of a majority in principal amount of the outstanding
notes may rescind any such acceleration with respect to the notes and its
consequences.

     No Holder of a note may pursue any remedy under the Indenture unless:

          (1) the Trustee shall have received written notice of a continuing
     Event of Default;

          (2) the Trustee shall have received a request from Holders of at least
     25% in principal amount of the notes to pursue such remedy;

          (3) the Trustee shall have been offered indemnity reasonably
     satisfactory to it;

          (4) the Trustee shall have failed to act for a period of 60 days after
     receipt of such notice, request and offer of indemnity; and

          (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority in
     principal amount of the notes;

provided, however, such provision does not affect the right of a Holder of any
note to sue for enforcement of any overdue payment thereon.

     The Holders of a majority in principal amount of the notes then outstanding
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 limitations specified in the Indenture. The Company must file annually
with the Trustee a written statement as to compliance with the covenants
contained in the Indenture.

          (6) make any note payable in money other than that stated in such
     note;

     payment of principal of, or premium, if any, or interest on, any note;

          (3) to reflect the release of any Subsidiary Guarantor from its
     Guarantee of the notes, or the addition of any Subsidiary of the Company as
     a Subsidiary Guarantor, in the manner provided in the Indenture;

          (4) to comply with any requirement of the SEC in order to effect or
     maintain the qualification of the Indenture under the Trust Indenture Act;
     or

          (5) to make any change that would provide any additional benefit to
     the Holders or that does not adversely affect the rights of any Holder of
     the notes in any material respect.

     Holders of a majority in aggregate principal amount of the notes then
outstanding may waive any past default under the Indenture, except a default in
the payment of principal, premium, if any, or interest.

     The Company may, at its option and at any time, elect to have its
obligations discharged with respect to the outstanding notes ("Legal
Defeasance"). Such Legal Defeasance means that the Company will be deemed to
have paid and discharged the entire Indebtedness represented by such notes,

the obligations of the Company released with respect to certain covenants
described under "-- Certain Covenants" ("Covenant Defeasance"), and thereafter
any omission to comply with such obligations shall not constitute a Default or
Event of Default. In the event Covenant Defeasance occurs, certain events (not
including non-payment) described under "-- Events of Default" will no longer
constitute an Event of Default.

     In order to exercise either Legal Defeasance or Covenant Defeasance under
the Indenture:

          (1) the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders of the notes, cash in U.S. Legal Tender,
     U.S. Government Securities, or a combination thereof, in such amounts as

     independent public accountants, to pay the principal of, premium, if any,
     and interest on the outstanding amount of the notes on the Maturity Date or
     on the applicable mandatory redemption date, as the case may be, of such
     principal or installment of principal, premium, if any, or interest;

          (2) in the case of Legal Defeasance, the Company must deliver 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 date
     of the Indenture, 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 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;

          (3) in the case of Covenant Defeasance, the Company shall have
     delivered to the Trustee an opinion of counsel reasonably acceptable to the
     Trustee to the effect that the Holders of the 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 on the date of such deposit or 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 shall not result in a
     breach or violation of, or constitute a default under the Indenture or any
     other material agreement or instrument to which the Company is a party or
     by which the Company is bound;

                                        53

          (6) the Company shall have delivered to the Trustee an officers'
     certificate stating that the deposit was not made by the Company with the
     intent of preferring the Holders of the notes over other creditors of the
     Company or with the intent of defeating, hindering, delaying or defrauding
     creditors of the Company or others; and

          (7) the Company shall have delivered to the Trustee an officers'
     certificate and an opinion of counsel each stating that the Company has
     complied with all conditions precedent provided for relating to the Legal
     Defeasance or the Covenant Defeasance.

GOVERNING LAW

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

THE TRUSTEE

     United States Trust Company of New York is the Trustee under the Indenture.
Its address is 114 West 47th Street, New York, New York 10036-1532. The Company
has also appointed the Trustee as the initial Registrar, Transfer Agent and
Paying Agent under the Indenture.

     The Trustee is permitted to become an owner or pledgee of the notes and may
otherwise deal with the Company or its Subsidiaries or Affiliates with the same
rights it would have if it were not Trustee. If, however, the Trustee acquires
any conflicting interest (as defined in the Trust Indenture Act) after an Event
of Default has occurred and is continuing, it must eliminate such conflict or
resign.

     In case an Event of Default shall occur (and be continuing), the Trustee
will be required to use the degree of care and skill of a prudent person in the
conduct of such person's own affairs. The Trustee will be under no obligation to
exercise any of its powers under the Indenture at the request of any of the
Holders of the notes, unless such Holders have offered the Trustee indemnity
reasonably satisfactory to it.

BOOK ENTRY, DELIVERY AND FORM

     The new notes will be issued in the form of one or more global securities.
The global securities will be deposited with, or on behalf of, the Depositary
and registered in the name of the Depositary or its nominee. Except as set forth
below, the global securities may be transferred, in whole and not in part, only
to the Depositary or another nominee of the Depositary. Investors may hold their
beneficial interests in the global securities directly through the Depositary if
they have an account with the Depositary or indirectly through organizations
which have accounts with the Depositary.

     Notes that are issued as described below under "-- Certificated Notes" will
be issued in definitive form. Upon the transfer of notes in definitive form,
such notes will, unless the global securities have previously been exchanged for
notes in definitive form, be exchanged for an interest in the global securities
representing the aggregate principal amount of notes being transferred.

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

                                        54
   57

     The Company expects that pursuant to procedures established by the
Depositary, upon the issuance of the global securities, the Depositary will
credit, on its book-entry registrations and transfer system, the aggregate
principal amount of new notes represented by such global securities to the
accounts of participants exchanging outstanding notes. Ownership of beneficial
interests in the global securities will be limited to participants or Persons
that may hold interests through participants. Ownership of beneficial interests
in the global securities will be shown on, and the transfer of those ownership
interests will be effected only through, records maintained by the Depositary
(with respect to participants' interest) and such participants (with respect to
the owners of beneficial interests in the global securities other than
participants). The laws of some jurisdictions may require that certain
purchasers of securities take physical delivery of such securities in definitive
form. Such limits and laws may impair the ability to transfer or pledge
beneficial interests in the global securities.

     So long as the Depositary, or its nominee, is the Holder of the global
securities, the Depositary or such nominee, as the case may be, will be
considered the sole legal owner and Holder of the notes for all purposes of the
notes and the Indenture. Except as set forth below, you will not be entitled to
have the notes represented by the global securities registered in your name,
will not receive or be entitled to receive physical delivery of certificated
notes in definitive form and will not be considered to be the owner or Holder of
any notes under the global securities. The Company understands that under
existing industry practice, in the event an owner of a beneficial interest in
the global securities desires to take any action that the Depositary, as the
Holder of the global securities, is entitled to take, the Depositary will
authorize the participants to take such action, and that the participants will
authorize beneficial owners owning through such participants to take such action
or would otherwise act upon the instructions of beneficial owners owning through
them.

     The Company will make all payments on notes represented by the global
securities registered in the name of and held by the Depositary or its nominee
to the Depositary or its nominee, as the case may be, as the owner and Holder of
the global securities.

     The Company expects that the Depositary or its nominee, upon receipt of any
payment in respect of the global securities, will credit participants' accounts
with payments in amounts proportionate to their respective beneficial interests
in the aggregate principal amount of the global securities as shown on the
records of the Depositary or its nominee. The Company also expects that payments
by participants to owners of beneficial interest in the global securities held
through such participants will be governed by standing instructions and
customary practices and will be the responsibility of such participants. The
Company will not have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests in the global securities for any notes or for maintaining, supervising
or reviewing any records relating to such beneficial ownership interests or for
any other aspect of the relationship between the Depositary and its participants
or the relationship between such participants and the owners of beneficial
interests in the global securities owning through such participants.

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

CERTIFICATED NOTES

     Subject to certain conditions, the notes represented by the global
securities will be exchangeable for certificated notes in definitive form of
like tenor as such notes if:

          (1) the Depositary notifies the Company that it is unwilling or unable
     to continue as Depositary for the global securities and a successor is not
     promptly appointed or if at any time the Depositary ceases to be a clearing
     agency registered under the Exchange Act; or

                                        55
   58

          (2) the Company in its discretion at any time determines not to have
     all of the notes represented by the global securities. Any notes that are
     exchangeable pursuant to the preceding sentence will be exchanged for
     certificated notes issuable in authorized denominations and registered in
     such names as the Depositary shall direct. Subject to the preceding, the
     global securities are not exchangeable, except for global securities of the
     same aggregate denominations to be registered in the name of the Depositary
     or its nominee.

                       FEDERAL INCOME TAX CONSIDERATIONS

FEDERAL INCOME TAX CONSIDERATIONS OF THE EXCHANGE OF OUTSTANDING NOTES FOR NEW
NOTES

     The following discussion is a summary of certain federal income tax
considerations relevant to the exchange of outstanding notes for new notes, but
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 (the
"Code"), 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.

     We believe that the exchange of outstanding notes for new notes should not
be an exchange or otherwise a taxable event to a holder for United States
federal income tax purposes. Accordingly, a holder should have the same adjusted
issue price, adjusted basis and holding period in the new notes as it had in the
outstanding notes immediately before the exchange.

FEDERAL INCOME TAX CONSIDERATIONS TO NON-U.S. HOLDERS OF OWNERSHIP AND
DISPOSITION OF NEW NOTES

     The following discussion summarizes certain U.S. federal income tax
consequences of the ownership and disposition of the new notes by an initial
holder of outstanding notes who is a non-U.S. holder. This discussion is based
upon the Code, existing and proposed Treasury Regulations, and judicial
decisions and administrative interpretations thereunder, as of the date hereof,
all of which are subject to change, possibly with retroactive effect, or are
subject to different interpretations. We cannot assure you that the Internal
Revenue Service (the "IRS") will not challenge one or more of the tax
consequences described herein, and we have not obtained, nor do we intend to
obtain, a ruling from the IRS or an opinion of counsel with respect to the U.S.
federal tax consequences of acquiring, holding or disposing of the notes.

     In this discussion, we do not purport to address all tax considerations
that may be important to a particular non-U.S. holder in light of the non-U.S.
holder's circumstances, or to certain categories of investors (such as certain
financial institutions, insurance companies, tax-exempt organizations, dealers
in securities, persons who hold the notes through partnerships or other
pass-through entities, U.S. expatriates, or persons who hold the new notes as
part of a hedge, conversion transaction, straddle or other risk reduction
transaction) that may be subject to special rules. This discussion is limited to
initial non-U.S. holders who purchased the outstanding notes for cash at the
original offering price and who held those notes and will hold the new notes
received in exchange therefor as capital assets. This discussion also does not
address the tax considerations arising under the laws of any foreign, state or
local jurisdiction.

     YOU SHOULD CONSULT YOUR OWN TAX ADVISORS AS TO THE PARTICULAR TAX
CONSEQUENCES TO YOU OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NEW
NOTES, INCLUDING THE EFFECT AND APPLICABILITY OF STATE, LOCAL OR FOREIGN TAX
LAWS.

     You are a non-U.S. holder for purposes of this discussion if you are not:

     - an individual U.S. citizen or resident alien;

     - a corporation, or other entity taxable as a corporation for U.S. federal
       income tax purposes, that was created or organized in or under U.S. law
       (federal or state);

                                        56
   59

     - an estate whose world-wide income is subject to U.S. federal income
       taxation; or

     - a trust that either is subject to the supervision of a court within the
       United States and which has one or more U.S. persons with authority to
       control all substantial decisions, or has a valid election in effect
       under applicable U.S. Treasury regulation to be treated as a U.S. person.

     If a partnership holds notes, the tax treatment of a partner generally will
depend upon the status of the partner and upon the activities of the
partnership. If you are a partner of a partnership holding outstanding notes, we
suggest that you consult your tax advisor.

  U.S. Federal Withholding Tax

     The 30% U.S. federal withholding tax will not apply to any payment of
principal or interest to you on the new notes provided that:

     - you do not actually (or constructively) own 10% or more of the total
       combined voting power of all classes of our voting stock within the
       meaning of the Code and the U.S. Treasury regulations;

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

     - you are not a bank whose receipt of interest on the new notes is pursuant
       to a loan agreement entered into in the ordinary course of business.

In each case, (a) you must provide your name and address on an IRS Form W-8BEN
(or successor form), and certify under penalty of perjury, that you are not a
U.S. person, (b) a financial institution holding the new notes on your behalf
must certify, under penalty of perjury, that it has received an IRS Form W-8BEN
(or successor form) from you and must provide us with a copy, or (c) you must
hold your new notes directly through a "qualified intermediary," and the
qualified intermediary must have sufficient information in its files indicating
that you are a non-U.S. holder. A qualified intermediary is a bank, broker or
other intermediary that is acting out of a non-U.S. branch or office and has
signed an agreement with the IRS providing that it will administer all or part
of the U.S. tax withholding rules under specified procedures.

     If you cannot satisfy the requirements described above, payments of
principal and interest made to you will be subject to the 30% U.S. federal
withholding tax, unless you provide us with a properly executed (1) IRS Form
W-8BEN (or successor form) claiming an exemption from (or a reduction of)
withholding under the benefit of a tax treaty or (2) IRS Form W-8ECI (or
successor form) stating that interest paid on the new notes is not subject to
withholding tax because it is effectively connected with your conduct of a trade
or business in the United States.

     The 30% U.S. federal withholding tax generally will not apply to any gain
or income that you realize on the sale, exchange, or other disposition of the
new notes.

  U.S. Federal Estate Tax

     If you are an individual, your estate will not be subject to U.S. federal
estate tax on new notes beneficially owned by you at the time of your death,
provided that (1) you do not own 10% or more of the total combined voting power
of all classes of our voting stock (within the meaning of the Code and the U.S.
Treasury Regulations) and (2) interest on such notes would not have been, if
received at the time of your death, effectively connected with the conduct by
you of a trade or business in the United States.

  U.S. Federal Income Tax

     If you are engaged in a trade or business in the United States and interest
on the new notes is effectively connected with the conduct of that trade or
business, you will be subject to U.S. federal income tax on the interest on a
net income basis (although exempt from the 30% withholding tax) in the same
manner as if you were a U.S. person as defined under the Code. In addition, if
you are a foreign

                                        57
   60

corporation, you may be subject to a branch profits tax equal to 30% (or lower
applicable treaty rate) of your earnings and profits for the taxable year,
including earnings and profits from an investment in the new notes, that are
effectively connected with the conduct by you of a trade or business in the
United States.

     Any gain or income realized on the sale, exchange, or redemption of the new
notes generally will not be subject to U.S. federal income tax unless:

     - that gain or income is effectively connected with the conduct of a trade
       or business in the United States by you,

     - you are an individual who is present in the United States for 183 days or
       more in the taxable year of that disposition, and certain other
       conditions are present, or

     - the gain represents accrued interest, in which case the rules for
       interest would apply.

  Backup Withholding and Information Reporting

     Backup withholding and information reporting will not apply to payments of
principal and interest on the new notes by us or our agent to you if you certify
as to your non-U.S. holder status under penalties of perjury or you otherwise
qualify for an exemption (provided that neither we nor our agent know or have
reason to know that you are a U.S. person or that the conditions of any other
exemptions are not in fact satisfied).

     The payment of the proceeds of the disposition of new notes to or through
the U.S. office of a U.S. or foreign broker will be subject to information
reporting and backup withholding unless you provide the certification described
above or you otherwise qualify for an exemption. The proceeds of a disposition
effected outside the United States by a non-U.S. holder to or through a foreign
office of a broker generally will not be subject to backup withholding or
information reporting. However, if such broker is a U.S. person, a controlled
foreign corporation for U.S. tax purposes, a foreign person 50% or more of whose
gross income from all sources for certain periods is effectively connected with
a trade or business in the United States, or a foreign partnership that is
engaged in the conduct of a trade or business in the United States or that has
one or more partners that are U.S. persons who in the aggregate hold more than
50 percent of the income or capital interests in the partnership, information
reporting requirements will apply unless such broker has documentary evidence in
its files of your non-U.S. status and has no actual knowledge or reason to know
to the contrary or unless you otherwise qualify for an exemption. Any amount
withheld under the backup withholding rules will be refunded or is allowable as
a credit against your federal income tax liability, if any, provided the
required information or appropriate claim for refund is provided to the IRS.

                              PLAN OF DISTRIBUTION

     Based on interpretations by the staff of the Securities and Exchange
Commission in no action letters issued to third parties, we believe that you may
transfer new notes issued under the exchange offer in exchange for the
outstanding notes if:

     - you acquire the new notes in the ordinary course of your business; and

     - you are not engaged in, and do not intend to engage in, and have no
       arrangement or understanding with any person to participate in, a
       distribution of such new notes.

     You may not participate in the exchange offer if you are:

     - our "affiliate" within the meaning of Rule 405 under the Securities Act
       of 1933; or

     - a broker-dealer that acquired outstanding notes directly from us.

     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. To date, the staff of the
Securities and Exchange Commission has taken the position that broker-dealers
may fulfill their prospectus delivery requirements with respect to transactions
involving an exchange of securities such as this exchange offer, other than a
resale of an unsold allotment from the original sale of the outstanding notes,
with the prospectus contained in this registration statement. 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
outstanding notes where such outstanding notes were acquired as a result of
market-making activities or other trading activities. We have agreed that, for a
period of up to 180 days after the effective date of this registration
statement, 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 such date, all dealers effecting transactions in new notes may be required
to deliver a prospectus.

     If you wish to exchange new notes for your outstanding notes in the
exchange offer, you will be required to make representations to us as described
in "Exchange Offer -- Purpose and Effect of the Exchange Offer" and
"-- Procedures for Tendering -- Your Representations to Us" in this prospectus
and in the letter of transmittal. In addition, if you are a broker-dealer who
receives new notes for your own account in exchange for outstanding notes that
were acquired by you as a result of market-making activities or other trading
activities, you will be required to acknowledge that you will deliver a
prospectus in connection with any resale by you of such new notes.

     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; and

     - 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 of 1933. The letter of
transmittal states that by acknowledging that it will deliver and by delivering
a prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act of 1933.

                                        59
   62

     For a period of 180 days after the effective date of this registration
statement, 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 outstanding notes) other than commissions or concessions of any
broker-dealers and will indemnify the holders of the outstanding notes
(including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act of 1933.

                                 LEGAL MATTERS

     The validity of the new notes offered in this exchange offer will be passed
upon for us by Vinson & Elkins L.L.P. in reliance on the opinion of Commercial
Law Group, P.C. with respect to matters of Oklahoma law.

     Shannon T. Self, a shareholder in Commercial Law Group, P.C., is a director
of Chesapeake, and he beneficially owns 431,242 shares of our common stock.

                           FORWARD-LOOKING STATEMENTS

     This prospectus includes "forward-looking statements" within the meaning of
Section 27A of the Securities Act and Section 21E of the Exchange Act.
Forward-looking statements give our current expectations or forecasts of future
events. They include statements regarding oil and gas reserve estimates, planned
capital expenditures, the drilling of oil and gas wells and future acquisitions,
expected oil and gas production, cash flow and anticipated liquidity, business
strategy and other plans and objectives for future operations and expected
future expenses and use of net operating loss carryforwards.

     Although we believe the expectations and forecasts reflected in these and
other forward-looking statements are reasonable, we can give no assurance they
will prove to have been correct. They can be affected by inaccurate assumptions
or by known or unknown risks and uncertainties. Factors that could cause actual
results to differ materially from expected results are described under "Risk
Factors" and include:

     - the volatility of oil and gas prices;

     - our substantial indebtedness;

     - our commodity price risk management activities;

     - our ability to replace reserves;

     - the availability of capital;

     - uncertainties inherent in estimating quantities of oil and gas reserves;

     - projecting future rates of production and the timing of development
       expenditures;

     - uncertainties in evaluating oil and gas reserves of acquired properties
       and associated potential liabilities;

     - drilling and operating risks;

     - adverse effects of governmental and environmental regulation;

     - losses possible from pending or future litigation;

     - the strength and financial resources of our competitors;

     - the loss of officers or key employees; and

     - conflicts of interest our chief executive officer and chief operating
       officer may have as a result of their participation in company wells.

     We caution you not to place undue reliance on these forward-looking
statements, which speak only as of the date of this prospectus, and we undertake
no obligation to update this information. We urge you to carefully review and
consider the disclosures made in this prospectus and our reports filed with the
SEC and incorporated by reference herein that attempt to advise interested
parties of the risks and factors that may affect our business.
