                         REPORT OF INDEPENDENT AUDITORS


To the Participants and Administrator of the
Michael Baker Corporation Employee Stock Ownership 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 Michael Baker Corporation Employee Stock Ownership Plan (the "Plan") at
December 31, 2002 and 2001, 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 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 the 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.

MICHAEL BAKER CORPORATION
EMPLOYEE STOCK OWNERSHIP PLAN
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2002 AND 2001
-------------------------------------------------------------------------------


1.    DESCRIPTION OF PLAN

      GENERAL
      The following description of the Michael Baker Employee Stock Ownership
      Plan (the "ESOP", or the "Plan") provides only general information.
      Participants should refer to the Plan agreement for a more complete
      description of the Plan's provisions.

      The ESOP is a defined contribution plan that provides all eligible
      employees of Michael Baker Corporation (the "Company") with an opportunity
      to accumulate additional retirement benefits as well as invest in Company
      stock. The Plan is subject to provisions of the Employee Retirement Income
      Security Act of 1974, as amended ("ERISA").

      PARTICIPANT ACCOUNTS
      Each participant's account is credited with the participant's contribution
      and allocations of (a) the Company's contribution and (b) Plan earnings or
      losses, and charged with an allocation of certain administrative fees.
      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.

      CONTRIBUTIONS
      Participants contribute to the ESOP through a Section 401(k) Employee
      Salary Redirection Election. During 2001, participants were able to choose
      to have a percentage of their salaries (including commissions and
      overtime) withheld and contributed to the ESOP up to the lower of 18
      percent of the participant's salary or the annual limitation established
      by the Internal Revenue Service. Effective January 1, 2002, the Plan
      participants became able to choose to contribute up to the lower of 50
      percent of their salaries (including commissions and overtime) or the
      annual limitation established by the Internal Revenue Service. The maximum
      amount of a participant's salary which may be eligible for withholding for
      any Plan year could not exceed $200,000 in 2002 and $170,000 in 2001. The
      ESOP also allows participants to roll over funds from a previous
      employer's tax-qualified plan or tax-qualified individual retirement
      account.

      Effective January 1, 2002, all employees who are eligible to make deferred
      contributions under this Plan and who have attained age 50 before the
      close of the plan year shall be eligible to make catch-up contributions in
      accordance with and subject to the limitation established by the Internal
      Revenue Service.

      COMPANY MATCHING CONTRIBUTIONS
      Under the provisions of the Plan, the Company will make a matching
      contribution to the participants' accounts in an amount of 100 percent of
      the first 5 percent and 50 percent of the next 1 percent of eligible
      salary (including commissions but excluding overtime) contributed by each
      participant. Contribution amounts over the 6 percent limit are not
      required to be matched by the Company. The Company's matching
      contributions were invested in not less than 25 percent of Michael Baker
      Corporation common stock in 2002, and not less than 25 percent of Michael
      Baker Corporation Common Stock or Series B Common Stock in 2001, with the
      remaining 75 percent invested in accordance with the participants'
      investment elections for participant contributions.

      Company matching contributions will not be made with respect to catch-up
      contributions.

MICHAEL BAKER CORPORATION
EMPLOYEE STOCK OWNERSHIP PLAN
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2002 AND 2001
-------------------------------------------------------------------------------



      The Board of Directors of the Company is authorized to make additional
      discretionary contributions to the ESOP from time to time. However, no
      discretionary contributions were made in 2002 or 2001.

      VESTING
      Participants are vested immediately in their contributions plus actual
      earnings thereon. All amounts in the participants' ESOP accounts that are
      attributable to the transfer of funds from a previously terminated
      retirement plan, the rollover from a previous employer's tax-qualified
      plan, and participant contributions are 100 percent vested and
      nonforfeitable at all times.

      All Company matching contributions will become 100 percent vested upon
      attainment of three years of service with the Company or earlier, upon
      attainment of normal retirement date, disability or death. If a
      participant leaves employment with the Company before attaining a vested
      interest in his or her Company contribution, the contributions are
      forfeited and will reduce future Company matching contributions.

      DISTRIBUTIONS
      The Plan provides for distribution of benefits upon retirement, total and
      permanent disability, death, or termination of employment for any other
      reason. The amount of distribution the participant or his or her
      beneficiary is entitled to is based on the vesting requirements discussed
      above. All distributions will be made in the form of a single, lump-sum
      distribution or in substantially equal annual installments over a period
      not exceeding five years. For participant accounts invested in the
      Company's common stock, distributions may be made in cash and/or shares of
      common stock, at the discretion of the participant.

      Effective January 1, 2003, participants may also make written application
      to the administrator for withdrawal of up to 50 percent of their vested
      account balance for certain limited situations qualifying as financial
      hardships under Internal Revenue Service ("IRS") guidelines in effect at
      the time of the withdrawal.

      PARTICIPANT LOANS
      A participant may borrow money from the portion of his or her account
      attributable to his or her own 401(k) plan contributions. Participant
      loans may be obtained in the sole event of immediate and heavy financial
      need, where the participant lacks other available resources. Effective
      January 1, 2003, participant loans may be obtained without the occurrence
      of an event of immediate and heavy financial need. Loan amounts shall not
      exceed the lesser of: (a) 50 percent of the participant's vested account
      balance, including rollovers, (b) $50,000 adjusted for pre-existing loans,
      or (c) such amount as may be determined by the plan administrator. All
      loans will be drawn against the participant's account among the respective
      investment options as directed, and are secured by the assets within the
      participant's accounts. Interest rates on outstanding notes receivable
      ranged from 5.25 percent to 10.5 percent at December 31, 2002 and 6
      percent to 10.5 percent at December 31, 2001.

      FORFEITED ACCOUNTS
      At December 31, 2002 and 2001, forfeited nonvested accounts totaled $0 and
      $68,168, respectively. These amounts will be used to reduce future
      employer contributions. Also, in 2002 and 2001, employer contributions
      were reduced by $613,733 and $829,880, respectively, from forfeited
      nonvested accounts.

      COMMON STOCK
      The ESOP enables participating employees to acquire an equity interest in
      Michael Baker Corporation (the "Company"); as such, contributions to the
      ESOP can be invested in the Company's common stock (common stock and
      Series B common stock).

      The ESOP's investment in the Company's common stock comprises 3,012,270
      shares (cost of $21,864,313) and 2,038,031 shares (cost of $14,232,668) at
      December 31, 2002 and 2001, respectively.

      During the fourth quarter of 2001, the Company announced that all of its
      Series B common stock would be exchanged into common stock. Under this
      program, each Series B share held by the ESOP was exchanged for
      approximately 1.018 shares of common stock during the first quarter of
      2002. Immediately following that exchange, the remaining Series B shares
      were automatically converted into common equivalents in accordance with
      provisions of the Company's Articles of Incorporation. As a result of the
      conversion, the Plan obtained an additional 23,452 shares of common stock
      at a price of $14 per share.

      The ESOP's investment in the Company's Series B common stock comprised
      1,217,221 shares (cost of $7,401,968) at December 31, 2001.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      BASIS OF ACCOUNTING
      Putnam Investments, Inc. ("Putnam) performs the recordkeeping function for
      the ESOP and the records are maintained on a cash basis. The financial
      statements included herein include all adjustments to reflect the
      financial statements on the accrual basis of accounting in accordance with
      accounting principles generally accepted in the United States of America.

      INVESTMENTS
      Investments are stated at fair value based upon quoted market values.
      Purchases and sales of securities are recorded on a trade-date basis. The
      investment in common stock of the Company is stated at publicly-traded
      closing market values as of December 31, 2002 and 2001. As of December 31,
      2002 and 2001, the ESOP owned approximately 36 percent and 39 percent,
      respectively, of the outstanding shares of the Company's common stock;
      therefore, such valuation might be subject to significant fluctuation in
      the event of a substantial liquidation of such holdings by the ESOP.

      The difference between the cost and current market value of investments
      purchased since the beginning of the period and the increase or decrease
      in such stated market value of investments held at the beginning of the
      period is included in the net appreciation (depreciation) in fair market
      value of investments in the statements of changes in net assets available
      for benefits.

      CONTRIBUTIONS
      Employee and employer contributions are recorded in the period during
      which the Company makes payroll deductions from Plan participants'
      earnings.

      DISTRIBUTIONS
      Distributions to participants are recorded when paid.

      USE OF ESTIMATES
      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make certain
      estimates and assumptions that may affect the reported amounts of assets,
      liabilities and changes therein, and disclosure of contingent assets and
      liabilities. Actual results could differ from those estimates.

      CONCENTRATION OF RISK
      Investments are exposed to various risks, such as interest rate, market
      and credit. Due to the level of risk associated with these investments and
      the level of uncertainty related to changes in the value of these
      investments, it is at least reasonably possible that changes in the near
      term could materially affect participants' account balances and the
      amounts reported in the statement of net assets available for benefits and
      the statements of changes in net assets available for benefits.

5.    TAX STATUS

      The Internal Revenue Service has determined and informed the Company by a
      letter dated June 21, 2000, that the Plan and related trust are designed
      in accordance with the applicable sections of the Internal Revenue Code
      ("IRC"). The Plan has been amended since receiving the determination
      letter. However, the plan administrator and the Plan's counsel believe
      that the Plan is designed and is currently being operated in compliance
      with applicable requirements of the IRC. In 2003, the Company filed for a
      new determination letter for the Plan.

6.    PLAN TERMINATION

      Although it has not expressed an intention to do so, the Company has the
      right under the Plan to discontinue its contributions at any time and to
      terminate the Plan subject to the provisions of ERISA. In the event of
      Plan termination, participants will become 100 percent vested in their
      accounts.

7.    RELATED PARTY TRANSACTIONS

      Certain investments of the Plan are mutual funds managed by Putnam. These
      transactions qualify as party-in-interest transactions.

      One of the investment fund options available to employees contains stock
      of Michael Baker Corporation, the plan sponsor. As a result, transactions
      related to this investment fund qualify as party-in-interest transactions
      (Note 1).
