                        Report of Independent Accountants


To the Participants and the Members of the Oversight Committee of the
Chesapeake Energy Corporation Savings and Incentive Stock Bonus Plan

In our opinion the accompanying statements of net assets available for benefits
and the related statements of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Chesapeake Energy Corporation Savings and Incentive Stock Bonus Plan (the
"Plan") at December 31, 2001 and 2000, and the changes in net assets available
for benefits for the years then ended, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Plan's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with auditing
standards generally accepted in the United States of America, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of Assets
(Held at End of Year) and Reportable Transactions are presented for the purpose
of additional analysis and are not a required part of the basic financial
statements but are supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. These supplemental schedules are the
responsibility of the Plan's management. These supplemental schedules have been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

CHESAPEAKE ENERGY CORPORATION
SAVINGS AND INCENTIVE STOCK BONUS PLAN
NOTES TO FINANCIAL STATEMENTS
------------------------------------------------------------------------------

1.       DESCRIPTION OF THE PLAN

         The following is a brief summary of the various provisions of the
         Chesapeake Energy Corporation Savings and Incentive Stock Bonus Plan
         (the "Plan"). Participants should refer to the Plan agreement for a
         complete description of the Plan's provisions.

         GENERAL - The Plan is a defined contribution plan, and, as of December
         31, 2001, covered all employees of Chesapeake Energy Corporation and
         its subsidiaries (the "Company") who have completed three consecutive
         months of employment and are age twenty-one or older. Effective January
         1, 2002 the Plan was amended to exclude from the plan employees of
         NOMAC Drilling Corporation, a subsidiary of the Company. The Plan is
         subject to the provisions of the Employee Retirement Income Security
         Act of 1974 ("ERISA").

         CONTRIBUTIONS - Each year, participants may contribute up to 15 percent
         of pre-tax annual compensation, as defined in the Plan. Participants
         may also contribute amounts representing rollover distributions from
         other qualified plans. During 2001 and 2000, the Company contributed
         100 percent of the first 10 percent of base compensation that a
         participant contributed to the Plan. Effective January 1, 2002 the Plan
         was amended to increase the maximum of employer matching contributions
         to 100 percent of the first 15 percent of participant contributions.
         Profit sharing contributions may be made at the discretion of the
         Company's board of directors. No discretionary profit sharing
         contributions were made in 2001 and 2000. Contributions are subject to
         certain limitations.

         The Company's matching contribution is used to purchase shares of
         Chesapeake Energy Corporation Common Stock (the "Common Stock") on the
         open market. Participants may also elect to direct all or a portion of
         their contributions into the Common Stock.

         PARTICIPANT ACCOUNTS - Each participant's account is credited with the
         participant's contribution and allocations of the Company's
         contribution and Plan earnings. Allocations are based on participant
         earnings or account balances, as defined. The benefit to which a
         participant is entitled is the benefit that can be provided from the
         participant's vested account balance.

         VESTING - Participants are immediately vested in their contributions
         plus actual earnings thereon. Vesting in the Company's matching and
         profit sharing contributions plus actual earnings thereon is based on
         years of credited service or participant's age. A participant will be
         100 percent vested after seven years of credited service. Additionally,
         a participant will become fully vested upon attaining age 55, early
         retirement age under the plan, and completing 5 years of service.

         PARTICIPANT NOTES RECEIVABLE - Participants may borrow from their
         accounts a minimum of $1,000 up to a maximum equal to the lesser of
         $50,000 or 50 percent of their vested account balance. Loan terms range
         from one to five years or up to ten years for the purchase of a primary
         residence. The loans are collateralized by the balance in the
         participant's account and bear interest at the Prime Interest Rate.
         Principal and interest is paid ratably through semi-

1.       DESCRIPTION OF THE PLAN, Continued

         monthly payroll deductions. Interest rates on loans outstanding at
         December 31, 2001 ranged from 5.00% to 9.75%.

         PAYMENT OF BENEFITS - Upon termination of service due to death,
         retirement or separation from service, a participant may elect to
         receive either a lump-sum amount equal to the value of the
         participant's vested interest in his or her account, annual
         installments, or have the value rolled over to another qualified plan
         or IRA. Those participants who were Plan participants as of December
         31, 1999 may elect to receive benefits in the form of annuity payments.

         AMOUNTS FORFEITED - Forfeited nonvested amounts are first used to pay
         administrative expenses of the Plan or to restore such amounts to
         re-employed participants. Any remaining forfeitures are used to reduce
         Company contributions into the Plan. Forfeited nonvested accounts
         totaled $151,097 and $104,548 at December 31, 2001 and 2000,
         respectively. During 2001 forfeited nonvested accounts of $124,957 were
         used to reduce employer matching contributions and $28,540 to pay
         administrative expenses of the Plan.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF ACCOUNTING - The financial statements of the Plan are prepared
         under the accrual method of accounting.

         USE OF ESTIMATES - The preparation of financial statements in
         conformity with generally accepted accounting principles requires
         management to make estimates and assumptions that affect the reported
         amounts of net assets available for benefits at the date of the
         financial statements and the changes in net assets available for
         benefits during the reporting period. Actual results could differ from
         those estimates.

         INVESTMENT VALUATION AND INCOME RECOGNITION - The Plan's investments
         are stated at fair value. Shares of registered investment companies are
         valued at quoted market prices which represent the net asset value of
         shares held by the Plan at year-end. Participant loans receivable are
         valued at outstanding principal balance, which approximates fair value.

         Purchases and sales of securities are recorded on a trade-date basis.
         Investment income is recorded on the accrual basis. Dividends are
         recorded on the ex-dividend date.

         The Plan presents, in the statement of changes in net assets available
         for benefits, the net appreciation (depreciation) in the fair value of
         investments which consists of the realized gains or losses and the
         unrealized appreciation (depreciation) on those investments.

         PAYMENT OF BENEFITS - Benefits are recorded when paid.

         RISKS AND UNCERTAINTIES - Investment securities are exposed to various
         risks, such as interest rate, market, and credit risk. Due to the level
         of risk associated with certain investment

                                       5

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, Continued

         securities, it is at least reasonably possible that changes in value of
         investment securities will occur in the near term and that such changes
         could materially affect participants' account balances and the amounts
         reported in the statement of net assets available for benefits and the
         statement of changes in net assets available for benefits.

5.       PARTY-IN-INTEREST TRANSACTIONS

         Certain Plan investments are shares of Chesapeake Energy Corporation
         common stock. These transactions represent investments in the Company,
         and, therefore, qualify as party-in-interest transactions. Further,
         certain Plan investments are shares of mutual funds managed by Fidelity
         Investments. Fidelity Management Trust Company is the trustee as
         defined by the Plan, and, therefore, transactions in mutual funds
         managed by Fidelity Investments qualify as party-in-interest
         transactions.

6.       TAX STATUS

         The Plan obtained its latest determination letter on April 22, 1997, in
         which the Internal Revenue Service stated that the Plan, as then
         designed, was in compliance with the applicable requirements of the
         Internal Revenue Code (the "IRC"). The Plan has been amended since
         receiving the determination letter. However, the plan administrator and
         the plan's tax counsel believe the Plan is currently designed and being
         operated in compliance with the applicable requirements of the IRC.
         Therefore, no provision for income taxes has been included in the
         plan's financial statements.
