             Report of Independent Registered Public Accounting Firm



To the Administrator of the
Parker Drilling Company Stock Bonus Plan



In our opinion, the accompanying statements of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Parker Drilling Company Stock Bonus Plan (the "Plan") at December 31,
2004 and 2003, and the changes in net assets available for benefits for the year
ended December 31, 2004, 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 statements in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards 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. The 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.

Parker Drilling Company Stock Bonus Plan
Notes to Financial Statements
December 31, 2004 and 2003
--------------------------------------------------------------------------------


1.      Summary of Significant Plan Provisions

        On September 1, 1980, Parker Drilling Company and its subsidiaries
        adopted the Parker Drilling Company Profit Sharing Plan, which was
        amended in 1983 to qualify as a 401(k) plan under the Internal Revenue
        Code. Effective September 1, 1985, the name of the plan was changed to
        the Parker Drilling Company Stock Bonus Plan (the "Plan"). The Plan was
        amended and restated generally effective January 1, 2001, to comply with
        certain tax laws. It was thereafter amended effective January 1, 2002 to
        reflect certain provisions of the Economic Growth and Tax Relief
        Reconciliation Act of 2001 ("EGTRRA"). The Plan was further amended
        effective January 1, 2003, and November 1, 2003 to comply with new tax
        laws and to incorporate various plan design and administrative changes.

        The Plan is a defined contribution plan and is subject to the provisions
        of the Employee Retirement Income Security Act of 1974 ("ERISA"). The
        following description of the Plan provides only general information.
        Participants should refer to the Summary Plan Description and the plan
        document for a more complete description of the Plan's provisions.

        Plan Administrator and Trustee
        The plan administrator is the Retirement Policy Committee which is
        comprised of persons appointed by the plan sponsor, Parker Drilling
        Company (the "Company"). JP Morgan Chase Bank is the trustee for the
        investments held by the Plan. JP Morgan Retirement Plan Services is the
        record keeper for the Plan.

        Eligibility
        Employees of participating employers of the Company, other than
        employees covered by certain collective bargaining agreements, leased
        employees, employees who are not citizens of the United States of
        America (except for certain resident aliens) and other excluded
        employees, are eligible to participate in the Plan on the first day of
        the month following the completion of three months of service with the
        Company.

        Contributions
        Participants may elect to contribute up to 30% of their eligible
        compensation, as defined in the Plan, on a pre-tax basis. Participants
        who have attained age 50 prior to the end of the plan year are eligible
        to make additional pre-tax "catch-up" contributions. All pre-tax
        employee contributions are subject to the applicable limitations of the
        Internal Revenue Code of 1986, as amended (the "Code"). Plan
        participants may also make rollover contributions to the Plan subject to
        the provisions of the Plan and the Code.

        Employer matching contributions are currently equal to 100% of the first
        3% of eligible compensation contributed by the participant to the Plan,
        plus 50% of the next 2% of eligible compensation contributed by the
        participant to the Plan. Matching contributions are credited to
        participant accounts on a monthly basis and are invested in Parker
        Drilling Company common stock. Employee pre-tax "catch-up" contributions
        are not eligible for employer matching contributions.

        The Company may, at its discretion, also contribute a profit sharing
        contribution to the Plan to be allocated to the accounts of eligible
        participants as described in the plan document. The Company did not make
        a profit sharing contribution for the year ended December 31, 2004.

        Vesting
        Participants are immediately and fully vested in the value of employee
        and employer contributions made to their accounts and related
        earnings/losses.

        Investment Program
        Participants direct the investment of 100% of their contributions and
        may transfer a portion or all of their account balance out of any fund
        into one or any combination of the other available funds. The investment
        fund options offered include 11 mutual funds. Participants may also
        elect to invest a portion of their account balance in a self-directed
        brokerage account, subject to the limitations of the Plan. Effective
        November 1, 2003, the Parker Drilling Company common stock was
        eliminated as an investment option for participant contributions.
        However, to the extent a participant had invested his/her account in the
        Parker Drilling Company common stock investment option, such investment
        may be retained as to contributions prior to November 1, 2003.

        Employer matching contributions are made in Parker Drilling Company
        common stock. However, participants may sell their shares of Company
        stock at any time and invest the proceeds in any of the other investment
        fund options available under the Plan.

        The Retirement Policy Committee periodically reviews the Plan's
        investment fund options and makes changes to the available options from
        time to time.

        Participant Loans
        The Plan permits participants to borrow a minimum of $1,000 up to a
        maximum amount equal to the lesser of $50,000 or 50% of their vested
        account balance. A participant may elect a repayment term of up to five
        years for general purpose loans or up to ten years if the loan is for
        the purchase of the participant's principal residence. Loans are secured
        by the balance in the participant's account and payments are generally
        made through payroll deductions. The interest rate for new loans is the
        prime rate plus one percentage point and is fixed for the term of the
        loan. A participant may only have one loan outstanding at any time. For
        the plan years ending December 31, 2004 and 2003, interest rates ranged
        from 5% to 10.5%.

        Withdrawals and Distributions
        A participant may receive benefit payments through any one of the
        methods provided by the Plan upon separation from service, retirement or
        financial hardship. Participants may withdraw their rollover and
        after-tax contributions, if any, from the Plan at any time. Participants
        may also make an in-service withdrawal of their vested account balance
        on or after attainment of age 59-1/2. Distributions from the Plan can be
        made in the form of a partial or single lump sum cash payment.
        Participants may elect an in-kind distribution of shares held in the
        Parker Drilling Company common stock investment option in lieu of cash,
        with fractional shares distributed in cash.

        Hardship withdrawals are allowed in the event of a deemed financial
        need, subject to the provisions of the Plan and the Code. Participants
        may withdraw up to 100% of their pre-tax contributions and are suspended
        for at least six months from making additional contributions to the
        Plan.

        Participant Accounts
        Participant accounts are adjusted to reflect all participant and
        employer contributions, withdrawals/distributions, earnings/losses and
        applicable expenses attributable to the accounts. The benefit to which a
        participant is entitled is the benefit that can be provided from the
        participant's vested account balance.

        Administrative Expenses
        The Plan pays all expenses incurred by the Plan except to the extent
        they are paid by the Company. During the plan year ended December 31,
        2004, certain administrative costs and expenses of the Plan totaling
        $33,092 were paid by the Company.

        Amendment and Termination of the Plan
        Although the Company has not expressed any intent to do so, the Plan may
        be amended or terminated at any time subject to the provisions of ERISA.

2.      Summary of Significant Accounting Policies

        Basis of Accounting
        The accompanying financial statements are presented on the accrual basis
        of accounting except benefit payments which are reported on the cash
        basis to conform with generally accepted accounting principles.

        Investment Valuation
        The Plan reports the investments in the financial statements at fair
        value. Investments in mutual funds and Parker Drilling Company common
        stock are reported at fair value based on quoted market prices.
        Investment income is recorded as earned and dividends are recorded on
        the ex-dividend date. Purchases and sales are recorded on a trade-date
        basis. Distributions to participants are recorded when paid.

        Use of Accounting Estimates
        The preparation of the financial statements in conformity with
        accounting principles generally accepted in the United States of America
        requires management to make estimates and assumptions that affect the
        accompanying financial statements and disclosures. Actual results could
        differ from those estimates.

        * Individual investment represents 5% or more of net assets available
          for plan benefits at the end of the year.

4.      Tax Status

        The Plan obtained its latest determination letter dated April 26, 2002,
        in which the Internal Revenue Service stated that the Plan, as then
        designed, was in compliance with the applicable requirements of the
        Code. Although the Plan has been amended since receiving the
        determination letter, management believes the Plan is currently designed
        and being operated in compliance with the applicable requirements of the
        Code and was therefore qualified (and the related trust was tax-exempt)
        as of December 31, 2004 and 2003.

5.      Risks and Uncertainties

        The Plan provides for various investment options in any combination of
        money market, bond, and equity mutual funds. Investment securities are
        exposed to various risks, such as interest rate, credit and overall
        market volatility risks. Due to the risks associated with certain
        investments, it is at least reasonably possible that changes in the
        values of investment securities will occur in the near term and that
        such changes may materially affect participants' 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.

6.      Party-In-Interest

        Certain plan investments are shares of Parker Drilling Company 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 JP Morgan or
        American Century. Transactions in mutual funds managed by JP Morgan
        qualify as party-in-interest transactions as a result of JP Morgan's
        role as the trustee for the Plan and transactions in mutual funds
        managed by American Century qualify as party-in-interest as a result of
        its affiliation with JP Morgan.

7.      Fund Allocation

        The Parker Drilling Company common stock fund includes contributions
        from the Company and participants. Participant contributions are
        directed solely by the participants. Contributions from the Company may
        be liquidated by the participant at any time and the proceeds invested
        in other investment fund options. All other funds are participant
        directed.

        The following table sets forth information related to the Parker
        Drilling Company common stock fund and other participant directed funds'
        assets available for plan benefits at December 31, 2004, and the changes
        in such assets for the year then ended.
