                        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, 2000 and 1999, 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
For Investment Purposes and Reportable Transactions are presented for the
purpose of additional analysis and are not a required part of these 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 ("ERISA"). These
supplemental schedules are the responsibility of the Plan's management. These
supplemental schedules have been subjected to the auditing procedures applied in
the audit 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.

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 covering all
         employees of Chesapeake Energy Corporation and its subsidiaries (the
         "Company") who have completed six consecutive months of employment and
         are age twenty-one or older. The Plan is subject to the provisions of
         the Employee Retirement Income Security Act of 1974 ("ERISA").
         Approximately 524 employees were actively participating in the Plan as
         of December 31, 2000.

         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. The Company contributes 100 percent of the first
         10 percent of base compensation that a participant contributes to the
         Plan. Additional amounts may be contributed at the option of the
         Company's board of directors. Contributions are subject to certain
         limitations. The Company's matching contribution is used to purchase
         shares of Chesapeake Energy Corporation Common Stock on the open
         market.

         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.

         VESTING - Participants are immediately vested in their contributions
         plus actual earnings thereon. Vesting in the Company's matching portion
         of their accounts plus actual earnings thereon is based on years of
         credited service. A participant is 100 percent vested after seven years
         of credited service.

         PARTICIPANT NOTES RECEIVABLE - Participants may borrow from their fund
         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 1-5 years or up to 10 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-monthly payroll
         deductions.

         PAYMENT OF BENEFITS - Upon termination 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, annuity payments or have the value rolled over to another
         qualified plan or IRA.

         AMOUNTS FORFEITED - Forfeited nonvested amounts are used to pay
         administrative expenses of the Plan or to restore such amounts to
         re-employed Participants. If there are any amounts forfeited remaining,
         they will be allocated to other Participants during the last quarter of
         the year in the same manner as other Company contributions. Forfeited
         nonvested accounts totaled $219,028 and $227,002 at December 31, 2000
         and 1999, respectively.

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.

         INVESTMENTS VALUATION AND INCOME RECOGNITION - The Plan's investments
         are stated at fair value as measured by quoted market prices, except
         for the guaranteed interest contract which is valued at contract 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 cost.

         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.

         INVESTMENT CONTRACT WITH INSURANCE COMPANY - In 1999, participants
         could invest in a benefit-responsive contract with Mass Mutual. Mass
         Mutual maintained the contributions in a pooled separate account. The
         account was credited with earnings on the underlying investments and
         charged for Plan withdrawals and administrative expenses. The contract
         was included in the financial statements at contract value as reported
         to the Plan by Mass Mutual. Contract value represented contributions
         made under the contract, plus earnings, less participant withdrawals
         and administrative expenses. Participants may ordinarily direct the
         withdrawal or transfer of all or a portion of their investment at
         contract value. In February, 2000, all assets of the Plan held by Mass
         Mutual and Smith Barney were transferred to Fidelity Investments.

         PAYMENT OF BENEFITS - Benefits are recorded when paid. Benefits related
         to participants who elected to withdraw from the Plan prior to December
         31, 2000, but received distributions subsequent to period end, totaled
         approximately $73,000.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, Continued

         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 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
         participant's account balances and the amounts reported in the
         statement of net assets available for plan benefits and the statement
         of changes in net assets available for plan benefits. For example, the
         quoted market price of Chesapeake Energy Common Stock included in the
         December 31, 2000 financial statements was $10.13 per share.
         Subsequently, the quoted market price of the stock decreased to $6.80
         per share as of July 1, 2001.

3.       INVESTMENTS

         The following investments were held by the Plan at December 31, 2000
         and 1999:

5.       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 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 Internal Revenue
         Code. Therefore, no provision for income taxes has been included in the
         plan's financial statements.

   The accompanying notes are an integral part of these financial statements.
