Chesapeake began operations in 1989 and completed its initial public offering in 1993. Our common stock trades on the New York Stock Exchange under the symbol CHK. Our principal executive offices are located at 6100 North Western Avenue, Oklahoma City, Oklahoma 73118, and our main telephone number at that location is (405) 848-8000. Chesapeake maintains a website at www.chkenergy.com. Information contained on our website is not part of this prospectus. In April 2001, we owned interests in approximately 6,700 producing oil and gas wells. 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.

RISK FACTORS You should carefully consider the following risk factors in addition to the other information included or incorporated by reference in this prospectus. Each of these risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our common stock or other securities. 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. The prices we are currently receiving for our production are near or at historic highs. 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: o worldwide and domestic supplies of oil and gas, o weather conditions, o the level of consumer demand, o the price and availability of alternative fuels, o the availability of pipeline capacity, 3 6 o the price and level of foreign imports, o domestic and foreign governmental regulations and taxes, o the ability of the members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls, o political instability or armed conflict in oil-producing regions, and o 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 December 31, 2000, we had long-term indebtedness of $945 million, which included bank indebtedness of $25 million. Our long-term indebtedness represented 75% of our total capitalization at December 31, 2000. If the Gothic merger had been completed as of December 31, 2000, our long-term indebtedness, on a pro forma basis, would have been $1.16 billion. Our level of indebtedness affects our operations in several ways, including the following: o a substantial portion of our cash flows must be used to service our indebtedness; for example, for the year ended December 31, 2000, approximately 22% of EBITDA (23% of EBITDA on a pro forma basis for the Gothic acquisition) was used to pay interest on our borrowings. We cannot assure you that our business will generate sufficient cash flows from operations to enable us to continue to meet our obligations under our indentures, o a high level of debt increases our vulnerability to general adverse economic and industry conditions, o 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, o our debt covenants may also affect our flexibility in planning for, and reacting to, changes in the economy and in our industry, and o a high level of debt may impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate or 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 and 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. 4 7 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. In 2000, we recorded reductions to oil and gas revenues of $30.6 million related to commodity price risk management activities. We cannot assure you that we will not experience additional reductions to oil and gas revenues from our commodity price risk management. If the hedges in existence at December 31, 2000 had been settled on that date, based upon futures prices as of that date, we would have incurred a loss of $89.3 million, which would have been recognized as price adjustments during the related months of future production. In addition, our commodity price risk management transactions may expose us to the risk of financial loss in certain circumstances, including instances in which: o our production is less than expected, o there is a widening of price differentials between delivery points for our production and the delivery point assumed in the hedge arrangement, or o 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 December 31, 2000 was $35 million, consisting of $31.5 million in letters of credit and $3.5 million in cash deposits. Future collateral requirements are uncertain, but will depend on arrangements with our counterparties and highly volatile natural gas and oil prices. 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 5 8 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 Chesapeake'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: o a change in our December 31, 2000 present value of proved reserves of $62 million and $13 million, respectively; and o 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. 6 9 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: o injury or loss of life, o severe damage to or destruction of property, natural resources and equipment, o pollution or other environmental damage, o clean-up responsibilities, o regulatory investigations and penalties, and o suspension of operations. 7 10 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: o unexpected drilling conditions, o title problems, o pressure or irregularities in formations, o equipment failures or accidents, o adverse weather conditions, o compliance with environmental and other governmental requirements, and o 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 U.S. These risks include the following: o adverse local political or economic developments, o exchange controls, o currency fluctuations, o royalty and tax increases, o retroactive tax claims, o negotiations of contracts with governmental entities, and o 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. 8 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 contracts. As a result of their participation, they routinely have significant accounts payable to us for joint interest billings and other related advances. As of December 31, 2000, Messrs. McClendon and Ward had payables to us of $2.0 million and $2.3 million, respectively, in connection with such participation.

Any of such transactions may be effected at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at varying prices determined at the time of sale or at negotiated or fixed prices, in each case as determined by the selling shareholders or by agreement between the selling shareholders and underwriters, brokers, dealers or agents, or purchasers. In connection with sales of the shares or otherwise, the selling shareholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares in the course of hedging the positions they assume. The selling shareholders may also sell shares short and deliver shares to close out such short positions, or loan or pledge shares to broker-dealers that in turn may sell such shares. The selling shareholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their securities, nor is there any underwriter or coordinating broker acting in connection with the proposed sale of shares by the selling shareholders. If the selling shareholders effect such transactions by selling shares to or through underwriters, brokers, dealers or agents, such underwriters, brokers, dealers or agents may receive compensation in the form of discounts, concessions or commissions from the selling shareholders or commissions from purchasers of shares for whom they may act as agent (which discounts, concessions or commissions as to particular underwriters, brokers, dealers or agents may be in excess of those customary in the types of transactions involved). The selling shareholders and any brokers, dealers or agents that participate in the distribution of the shares may be deemed to be underwriters, and any profit on the sale of shares by them and any discounts, concessions or commissions received by any such underwriters, brokers, dealers or agents may be deemed to be underwriting discounts and commissions under the Securities Act. In addition, the anti-manipulation provisions of Regulation M under the Securities Exchange Act of 1934 may apply to sales by the selling shareholders. Under the securities laws of certain states, the securities may be sold in such states only through registered or licensed brokers or dealers. In addition, in certain states the shares may not be sold unless the shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with. Chesapeake will pay all of the expenses incident to the registration, offering and sale of the shares to the public hereunder other than commissions, fees and discounts of underwriters, brokers, dealers and agents. Chesapeake has agreed to indemnify the selling shareholders and any underwriters against certain liabilities, 11 14 including liabilities under the Securities Act. Chesapeake will not receive any of the proceeds from the sale of any of the shares by the selling shareholders. To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. We will make copies of this prospectus, as amended or supplemented, available to the selling shareholders and have informed the selling shareholders of the need for delivery of the prospectus to purchasers at or prior to the time of any sale of their shares.

Undertakings (a) Chesapeake hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; (iii) to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by Chesapeake pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. II-4 20 (b) Chesapeake hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of Chesapeake's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of Chesapeake pursuant to the foregoing provisions, or otherwise, Chesapeake has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Chesapeake of expenses incurred or paid by a director, officer or controlling person of Chesapeake in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, Chesapeake will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. II-5 21 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, Chesapeake certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Oklahoma City, State of Oklahoma on April 4, 2001.
