  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS
  
  RESULTS OF OPERATIONS
  Solid progress continued in 1997 as the Company closed out its third
  successful year of improved profitability. During the year, record
  performances were achieved in funded and total backlog and in full-year
  total contract revenues and net income, while financial position was
  also further strengthened. All nine operating divisions of the Company's
  five business units were profitable for the first time in 1997, thereby
  contributing to an improvement in diluted earnings per share of $0.60
  per share in 1997, compared with $0.50 per share in 1996.
  
  TOTAL CONTRACT REVENUES
  Total contract revenues reached a record $446 million in 1997, up from
  $418 million in 1996. The Transportation, Energy and Civil units recorded
  the largest increases in total contract revenues of $14 million, 
  $12 million, and $9 million, respectively. Revenue growth from new heavy &
  highway construction work, particularly in Chicago, accounted for the
  Transportation unit's improvement, while the Energy unit's offshore platform
  operations in the Gulf of Mexico fueled its growth. The Civil unit's net
  increase resulted from higher revenues on new operations and maintenance
  ("O&M") contracts, despite lower revenues in its engineering division due
  to the 1997 completion of its significant project in Mexico.
  
  For 1996, total contract revenues increased from $355 million in 1995.
  The Civil unit posted the largest 1996 increase due primarily to the
  aforementioned engineering project in Mexico, which was new in 1996 and 
  generated revenues of $24 million for that year. The Buildings and
  Transportation units were also significant contributors to the overall
  increase with improvements of $12 million and $11 million, respectively.
  Revenue growth in the construction divisions of each of these two units
  caused their respective improvements.
  
  
  TOTAL CONTRACT REVENUES - 1997
                        
  BUILDINGS                28%
  CIVIL                    27%
  ENERGY                   12%
  ENVIRONMENTAL             5%
  TRANSPORTATION           28%
  
  
  GROSS PROFIT
  Gross profit increased to $51.9 million in 1997 from $48.6 million in 1996.
  As a percentage of total contract revenues, gross profit remained relatively
  constant at 12% in both 1997 and 1996. The gross profit percentage increased
  for all of the Company's business units except the Energy unit. The Civil
  and Transportation units registered the most significant improvements in 
  1997. While the Civil unit raised the gross profit percentages for both its
  engineering and O&M businesses, the recovery in the Transportation unit was
  attributable to its unfavorable performance on certain construction projects
  during 1996. The percentage decrease in the Energy unit resulted primarily 
  from lower margins associated with its new work added in 1997.
  
  The 1996 gross profit represented an increase from $40.0 million in 1995. As
  a percentage of total contract revenues, gross profit increased slightly in
  1996 from 11% in 1995. Lower gross profit percentages in the Transportation
  and Environmental units were offset by an improvement in the Energy unit. The
  percentage decline in the Transportation unit resulted from its 1996
  performance on certain construction projects, while Environmental's decrease
  followed the 1996 award of a major contract, under which the Company began
  working as a subcontractor instead of as the prime contractor. In the Energy 
  unit, Baker/MO received several awards of profitable new work in 1996 and 
  received the first full year's benefit from having terminated certain lower 
  margin and loss contracts during 1995.
  
  
  INCOME FROM OPERATIONS - 1997
                         
  BUILDINGS                  5%
  CIVIL                     45%
  CORPORATE/INSURANCE        2%
  ENERGY                    21%
  ENVIRONMENTAL              4%
  TRANSPORTATION            23%
  
  
  GENERAL AND ADMINISTRATIVE EXPENSES
  General and administrative ("G&A") expenses increased to $43.9 million in 
  1997 from $40.9 million in 1996. The 1997 increase principally reflected 
  international marketing costs and the Energy unit's investment in the
  Venezuela market. Expressed as a percentage of total contract revenues, G&A
  expenses remained constant at 9.8% in both 1997 and 1996.
  
  G&A expenses increased in 1996 from $34.9 million in 1995. This increase
  related to the general increase in revenue volumes, combined with higher
  marketing costs in several of the Company's business units.  G&A expenses
  also represented 9.8% of total contract revenues in 1995.
  
  OTHER INCOME AND EXPENSE
  Interest income increased to $552,000 in 1997 from $402,000 in 1996, due to
  the combination of a higher daily average investment amount and slightly
  higher interest rates in 1997. Other income increased to $811,000 in 1997
  from $50,000 in 1996, primarily due to gains realized on the sales of
  certain investments and income from a new joint venture related to work in
  the Gulf of Mexico.
  
  Interest expense decreased to $76,000 in 1996 from $336,000 in 1995, as a
  result of the Company's limited borrowings under its revolving credit 
  agreement during 1996. Interest income increased in 1996 from $221,000 in
  1995, due to the Company's maintenance of an invested cash balance throughout
  most of 1996. In 1995, the Company was in a borrowing position under its 
  revolving credit agreement for the majority of the year.
  
  INCOME TAXES
  The provision for income taxes resulted in an effective tax rate of 47% in
  1997, 48% in 1996, and 43% in 1995. The difference between these percentages
  and the 34% statutory U.S. federal rate is attributable primarily to state
  and foreign income taxes and foreign withholding taxes. The 1996 provision
  rate was unfavorably impacted by higher foreign income taxes paid in that 
  year. The 1995 provision rate was favorably impacted by the realization of a 
  $600,000 tax benefit from a joint venture.
  
  CONTRACT BACKLOG
  The Company's funded backlog, which consists of that portion of work
  represented by signed contracts and for which the procuring agency has
  appropriated and allocated the funds to pay for the work, was $393 million
  at December 31, 1997, an increase from $333 million at the end of 1996. The
  overall increase in funded backlog is attributable to new work added and
  transfers from unfunded backlog during the year. With the exception of the
  Environmental unit, each of the Company's business units entered 1998 with
  higher funded backlog than at the end of 1996.
  
  Total backlog, which incrementally includes that portion of contract value
  for which options are still to be exercised (unfunded backlog), was $649
  million at the end of 1997 versus $544 million at the end of 1996. All units
  showed higher total backlog at year-end 1997 than at year-end 1996.
  
  
  FUNDED BACKLOG - YEAR END 1997
                           
  BUILDINGS                   33%
  CIVIL                       21%
  ENERGY                       6%
  ENVIRONMENTAL                5%
  TRANSPORTATION              35% 
  
  
  LIQUIDITY AND CAPITAL RESOURCES
  Net cash provided by operating activities increased significantly in 1997 to
  $9.2 million, compared to $1.2 million in 1996 and $15.5 million in 1995. The
  1997 improvement is mainly attributed to a combination of the Company's
  higher net income and the collection of retention amounts totaling $3.0 
  million on a significant construction project.  The favorable 1995 cash flow
  from operations was largely related to the 19% reduction in total contract
  revenues for that year.
  
  Net cash used in investing activities was $2.5 million in 1997, compared to
  $3.7 million in 1996 and $2.3 million in 1995. These amounts solely comprise
  capital expenditures for all years. The 1997 decrease is attributable to
  higher 1996 expenditures for building improvements and office equipment
  related to the Buildings unit's 1996 relocation from Pittsburgh to 
  Coraopolis, PA, and higher vehicle and equipment purchases during 1996 to 
  meet the requirements of new O&M projects in the Civil unit.
  
  The Company did not use any cash in financing activities in 1997, compared
  to usage of $1.3 million in 1996 and $2.5 million in 1995. In late 1996, 
  pursuant to an announced stock repurchase program, the Company paid $1.3
  million to acquire approximately 208,000 treasury shares. In 1995, the
  Company totally repaid its borrowings under its revolving credit facility.
  
  Working capital increased to $36.2 million at December 31, 1997 from $27.4
  million at December 31, 1996. This year-end improvement is attributable to
  the Company's overall 1997 business growth. The Company's current ratios were
  1.41:1 and 1.36:1 at the end of 1997 and 1996, respectively.
  
  In June 1997, the Company converted its credit agreement with Mellon
  Bank, N.A. from secured to unsecured. The agreement continued to provide
  for a commitment of $25 million, which covers borrowings and letters of
  credit, through May 31, 2000. As of December 31, 1997, no borrowings were
  outstanding; however, letters of credit totaling $3.5 million were 
  outstanding under the agreement. Management believes that the credit
  agreement will be adequate to meet its borrowing and letter of credit
  requirements for at least the next year.
  
  The Company is required to provide bid and performance bonding on certain
  construction contracts. In October 1997, the Company's available bonding
  line was increased from $350 million to $500 million by Travelers 
  Casualty & Surety Company of America (formerly Aetna Casualty and Surety 
  Company of America). Management believes that its bonding line will be
  sufficient to meet its bid and performance needs for at least the next year.
  
  The Company has completed a preliminary assessment of its exposures
  relative to the upcoming change to the 21st century. While the Company
  continues to modify its own noncompliant systems and equipment that are
  integral to its business, it is also monitoring the compliance of third
  parties with which it interacts. Based on information currently
  available, management does not believe that the incremental costs
  associated with Year 2000 compliance will be material to the Company's
  consolidated results of operations or financial position.
  
  Short- and long-term liquidity is dependent upon appropriations of public
  funds for infrastructure and other government-funded projects, capital
  spending levels in the private sector, and the demand for the Company's 
  services in the oil and gas markets. Additional external factors such as
  price fluctuations in the energy industry and the effects of interest rates
  on private construction projects could affect the Company. At this time,
  management believes that its funds generated from operations and its
  existing credit facility will be sufficient to meet its operating and
  capital expenditure requirements for at least the next year.

  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
  1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
  PRINCIPLES OF CONSOLIDATION
  The consolidated financial statements include the accounts of the Company
  and its subsidiaries. All material intercompany accounts and transactions
  have been eliminated in consolidation.
  
  ACCOUNTING FOR CONTRACTS
  Total contract revenues have been recorded on the percentage-of-completion 
  method of accounting for the engineering and construction contracts in the
  Buildings, Civil, Environmental and Transportation Units. Contract revenues
  attributable to claims and unapproved change orders are recognized when
  realization is probable and the amounts can be reliably estimated. Earnings 
  on fixed-price contracts are determined by multiplying the total estimated 
  gross profit for the contracts by the percentage of physical completion to 
  date (which approximates costs incurred to date in relation to total 
  estimated costs), less earnings recognized in prior periods. Earnings under
  cost reimbursement contracts are recorded as costs are incurred and include 
  estimated fees in the proportion that costs incurred to date compare to total
  estimated costs.  As work is performed under long-term contracts, estimates
  of the costs are reviewed and, when necessary, revised on a current basis. 
  Contract costs include costs of subcontracts, direct labor, supplies and
  overhead. Estimated losses on contracts in progress, if significant, are
  recorded as they are identified.
  
  Total contract revenues for the operations and maintenance contracts within
  the Civil and Energy Units are primarily recognized as costs are incurred
  and related services are provided. The Civil Unit's government contracts are
  typically binding on the Company for a multi-year period and are renewable
  at the option of the respective government agency.  Modifications to contract
  terms that result in retroactive adjustments to contract revenues are
  recognized when realization is probable.
  
  ACCOUNTING FOR JOINT VENTURES
  In the accompanying Consolidated Balance Sheet, the Company records its
  interest in all majority-owned construction joint ventures based on the
  equity method of accounting for investments. The Company's proportionate
  share of majority-owned construction joint venture revenue and cost of
  contracts is included in the accompanying Consolidated Statement of
  Income. The Company's investment in these joint ventures, for which the
  related projects are expected to be completed within one year, is included
  within other current assets in the accompanying Consolidated Balance Sheet.
  
  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 assets and liabilities
  and the disclosure of contingent assets and liabilities as of the date of the
  financial statements, and the reported amounts of revenues and expenses for
  the reporting period. Actual results could differ from those which result
  from using the estimates. The use of estimates is an integral part of
  applying percentage-of-completion accounting for contracts.
  
  DEPRECIATION AND AMORTIZATION
  Depreciation on property, plant and equipment is recorded using straight-line
  and accelerated methods over the estimated useful lives of the assets, which
  range from three to 31 years. Amortization of intangible assets is provided
  primarily on a straight-line basis over the estimated useful lives of the
  assets, which range from five to 10 years. Upon disposal of property items, 
  the asset and related accumulated depreciation accounts are relieved of the 
  amounts recorded therein for such items and any resulting gain or loss is 
  reflected in income.
  
  GOODWILL
  Goodwill, which represents the excess of cost over net assets of acquired
  companies, is being amortized on a straight-line basis over periods ranging
  from 15 to 40 years.
  
  EARNINGS PER COMMON SHARE
  During 1997, the Company adopted Statement of Financial Accounting
  Standards No. 128 ("SFAS 128"), "Earnings Per Share," which changes the
  computation and presentation of earnings per share ("EPS"). The adoption of
  SFAS 128 requires the presentation of both basic and diluted EPS.  Basic EPS
  are computed using the weighted average of actual shares outstanding. Diluted
  EPS are computed using the sum of basic weighted average shares outstanding
  and the dilutive share equivalents under the Company's stock option plans. 
  Such dilutive share equivalents are computed using the treasury stock method.
  In accordance with SFAS 128, previously reported EPS amounts and the weighted
  average shares were required to be restated; however, the adoption of this 
  standard had no effect on the previously reported EPS amounts for 1996 and
  1995.
  
  Basic net income per share computations are based upon weighted averages of
  8,207,786, 8,372,034 and 8,363,552 shares outstanding for the years 1997, 
  1996 and 1995, respectively. Diluted net income per share computations are 
  based upon weighted averages of 8,299,083, 8,382,592 and 8,368,206 shares
  outstanding for the years 1997, 1996 and 1995, respectively.
  
  RECLASSIFICATIONS
  Certain 1996 and 1995 financial statement amounts have been reclassified
  to conform with 1997 classifications.
  
  2. CONTRACTS
  The total cost of contracts in progress (used to determine cost of work
  performed) plus accumulated gross profit recorded was $858,705,000 and
  $761,153,000 at December 31, 1997 and 1996, respectively. Billings to date
  on contracts in progress at December 31, 1997 and 1996 were $850,231,000 and
  $754,181,000, respectively. 
  
  Trade accounts receivable totaling $12,088,000 and $11,855,000 at 
  December 31, 1997 and 1996, respectively, relate to retainage provisions
  under long-term contracts which will be due upon completion of the contracts.
  Based on management's estimates, substantially all of the retention balance
  at December 31, 1997 is expected to be collected in 1998. 
  
  As of December 31, 1997 and 1996, accounts payable included amounts due to
  subcontractors of $8,888,000 and $8,051,000, respectively, which have been
  retained under contractual terms pending the completion and acceptance of
  the work performed by the subcontractors.
  
  Certain subsidiaries of the Company participate in joint ventures that are
  typically formed to accomplish a specific project and then dissolved upon
  completion of the project. The number of joint ventures in which the Company
  participates and the size, scope and duration of the projects vary between
  periods. The Company's equity investment in these joint ventures was
  $1,737,000 and $1,612,000 at December 31, 1997 and 1996, respectively.
  
  Consistent with industry practice, within each of the Company's operating
  units, credit is granted to customers for the payment of services rendered. 
  Although the Company has a diversified client base, a substantial portion of
  its receivables and net underbillings reflected in the accompanying
  Consolidated Balance Sheet is dependent upon U.S. federal and state
  government appropriations.
  
  Internationally, the Company conducts business in certain countries where
  unstable governments subject the Company's related trade receivables, due
  from subsidiaries of major oil companies, to unique collection delays. Based
  upon past experience with these clients, management believes that these
  receivables will be fully collectible.
  
  3. BUSINESS SEGMENT INFORMATION

  6. LONG-TERM DEBT AND BORROWING AGREEMENTS
  In June 1997, the Company entered into an unsecured credit agreement (the
  "Agreement") with Mellon Bank, N.A. (the "Bank"). The Agreement provides for
  a commitment of $25 million through May 31, 2000. The commitment includes
  the sum of the principal amount of revolving credit loans outstanding and
  the aggregate face value of outstanding letters of credit. 
  
  As of December 31, 1997, no borrowings were outstanding; however, letters of
  credit totaling $3,517,000 were outstanding under the Agreement.
  
  The Agreement provides for the Company to borrow at the Bank's prime interest
  rate or at other indexed rates that may be lower, and for the Company to meet
  certain cash flow, leverage, interest coverage and tangible net worth 
  requirements. Under the Agreement, the Company pays the Bank commitment fees
  of 3/8% per year based on the unused portion of the commitment. 
  
  The Company did not borrow under the Agreement during 1997. For the period 
  during 1996 in which the Company was in a net borrowing position, the average
  daily balance outstanding was $324,000 at a weighted average rate of 8.5%. 
  The proceeds of the 1996 loans under the Agreement were used for various 
  working capital requirements.
  
  7. CAPITAL STOCK
  During 1996, the Board of Directors authorized the repurchase of up to
  500,000 shares of the Company's common stock in the open market. During 
  1996, the Company repurchased 207,560 treasury shares of common stock at 
  market prices ranging from $5.63 to $6.25 per share, for a total price 
  of $1,260,000.
  
  The Company's Articles of Incorporation authorize the issuance of 300,000
  shares of Cumulative Preferred Stock, par value $1 per share. At December 31,
  1997, there were no shares of such Preferred Stock outstanding.
  
  8. LEASE COMMITMENTS
  Rent expense under noncancelable leases was $10,364,000 in 1997, $9,972,000
  in 1996 and $8,388,000 in 1995. 
  
  Minimum annual rentals payable under noncancelable leases in each of the
  five years after December 31, 1997 are $10,436,000, $8,203,000, $6,550,000,
  $4,467,000 and $1,726,000, respectively. These noncancelable leases relate
  to office space, computer equipment, office equipment and vehicles, with
  lease terms ranging from one to 10 years.

  As of December 31, 1997, the Company had a U.S. net operating loss
  carryforward of $288,000. This carryforward expires in the year 2010.
  
  The Company's U.S. income tax returns have been examined and accepted by
  the Internal Revenue Service for the years 1990 through 1994. Management
  believes that adequate provisions have been made for income taxes at
  December 31, 1997.
  
  10. CONTINGENCIES
  The Company is self-insured for its primary layer of professional liability
  insurance through a wholly-owned captive insurance subsidiary.  The secondary
  layer of the professional liability insurance continues to be provided,
  consistent with industry practice, under a "claims-made" insurance policy
  placed with an independent insurance company. Under claims-made policies, 
  coverage must be in effect when a claim is made.  This insurance is subject
  to standard exclusions.
  
  The Company is self-insured up to certain limits with respect to its workers'
  compensation and general liability exposures. Provisions for losses expected
  for these exposures are recorded based upon the Company's estimates of the 
  aggregate liability for claims incurred. Such estimates utilize certain
  actuarial assumptions followed in the insurance industry. Insurance coverage
  is obtained for catastrophic exposures as well as those risks required to be 
  insured by law or contract. 
  
  The Company has been named as a defendant or co-defendant in legal
  proceedings wherein substantial damages are claimed. Such proceedings are
  not uncommon to the Company's business. After consultations with counsel,
  management believes that the Company has recognized adequate provisions for
  these proceedings and their ultimate resolutions will not have a material 
  adverse effect on the consolidated financial position or annual results of
  operations of the Company. 
  
  The only significant proceeding relates to a lawsuit brought in 1987 in the
  Supreme Court of the State of New York, Bronx County, by the Dormitory
  Authority of the State of New York against a number of parties, including the
  Company and one of its wholly-owned subsidiaries, that asserts breach of 
  contract and alleges damages of $13,000,000. The Company, which was not a
  party to the contract underlying the lawsuit, contends that there is no
  jurisdiction with respect to the Company and that it cannot be held liable
  for any conduct of the subsidiary. Both the Company and the subsidiary are
  contesting liability issues and have filed cross-claims and third-party
  claims against other entities involved in the project. 
  
  In the Company's ordinary course of business, many of its public contracts
  are subject to recurring audits by the Defense Contract Audit Agency ("DCAA")
  and other governmental entities. During 1997, DCAA commenced an audit of
  certain contracts for the years 1992 through 1995.  DCAA has not yet issued
  its preliminary audit report and, at this time, management is unable to
  determine the significance, if any, of this matter.
  
  At December 31, 1997, certain subcontractors performing work on uncompleted
  Company and joint-venture construction contracts and certain contractors on
  construction management projects had not been required to furnish performance
  bonds. In the opinion of management, provision has been made for all costs
  that will be incurred as a result of such contractors not performing in 
  accordance with their agreements.
  
  11. EMPLOYEE STOCK OWNERSHIP PLAN AND TRUST
  The Company maintains a defined contribution retirement program through an
  Employee Stock Ownership Plan ("ESOP"), in which substantially all employees
  are eligible to participate. In addition to providing a vehicle for 
  investment in Company stock, the ESOP offers participants several other
  investment options. Contributions to the ESOP are derived from a 401(k) 
  Salary Redirection Program with a Company matching contribution, and a
  discretionary contribution as determined by the Company's Board of Directors.
  Under the 401(k) Salary Redirection Program, the Company matches 100% of the
  first 5% of eligible salary contributed by participants. Beginning in 
  February 1998, the Company will match 100% of the first 5-1/2% of eligible 
  salary contributed by participants. Effective in July 1997, participants were
  enabled to direct not less than 50% of the Company's matching contributions 
  to be invested in Michael Baker Corporation Common Stock, with the remaining
  50% being available to invest in Baker Common Stock or mutual funds, as
  directed by the participants. Prior to July 1997, the Company's matching
  contributions were required to be invested 100% in Baker Common Stock.
  Company contributions under this program amounted to $3,321,000, $3,306,000
  and $2,912,000 in 1997, 1996 and 1995, respectively.
  
  As of December 31, 1997, the market value of all ESOP investments was
  $79,248,000, of which 47% represented the market value of the ESOP's
  investment in Michael Baker Corporation Common Stock. The Company's ESOP
  held 45% of the shares and 72% of the voting power for the outstanding
  Common Stock and Series B Common Stock of the Company at the end of 1997.
  
  12. STOCK OPTION PLANS
  As of December 31, 1997, the Company has two fixed stock option plans.  Under
  the 1995 Stock Incentive Plan (the "Plan"), the Company may grant options for
  an aggregate of 500,000 shares of Common Stock to key employees. Under the 
  1996 Nonemployee Directors' Stock Incentive Plan (the "Directors Plan"), the 
  Company may grant options for an aggregate of 150,000 shares of Common Stock
  to nonemployee board members. Under both plans, the exercise price of each 
  option equals the market price of the Company's stock on the date of grant. 
  One-fourth of the options granted become immediately vested, and the 
  remaining three-fourths vest in annual one-fourth increments under the Plan, 
  while the options under the Directors Plan are fully vested at date of 
  grant. Vested options remain exercisable for a period of ten years from the 
  grant date under both plans.
  
  Under the Directors Plan, each nonemployee director was issued 500
  restricted shares of common stock for a total of 4,500 and 3,500 shares of
  restricted stock issued in 1997 and 1996, respectively. Restrictions on the
  shares expire two years after the issue date.
  
  The following table summarizes all stock option activity for both plans
  in 1997 and 1996:

  *Average life remaining in years

  During 1996, the Company adopted Statement of Financial Accounting
  Standards No. 123 ("SFAS 123"), "Accounting for Stock-Based Compensation," 
  for disclosure purposes only. As allowed under SFAS 123, the Company
  continues to apply APB Opinion No. 25, "Accounting for Stock Issued to
  Employees," and related Interpretations in its accounting for stock-based
  compensation plans. Accordingly, no compensation cost was recognized in 1997
  and 1996. If compensation costs for the Company's stock incentive plans had
  been determined based on the fair value at the grant dates for awards under
  those plans, consistent with the method prescribed by SFAS 123, the Company's
  net income and diluted net income per share amounts would have been reduced.
  
  The Company's pro forma net income amounts would have been $4,725,000,
  $4,077,000 and $2,763,000 for the years ended December 31, 1997, 1996 and 
  1995, respectively. The Company's pro forma diluted net income per share
  would have been $0.57, $0.49 and $0.33 for the years ended December 31, 1997,
  1996 and 1995, respectively.
  
  The fair value of options on the respective grant dates was estimated using
  a Black-Scholes option pricing model with certain assumptions. The key 
  assumptions used include a weighted average risk-free interest rate of 7.0%,
  weighted average expected volatility of 51.8%, an expected option life of 6
  years, and a 0% expected dividend yield.

  REPORT OF INDEPENDENT ACCOUNTANTS
  To the Shareholders and Board of Directors 
  of Michael Baker Corporation:
  
  In our opinion, the accompanying consolidated balance sheet and the
  related consolidated statements of income, of shareholders' investment
  and of cash flows present fairly, in all material respects, the
  financial position of Michael Baker Corporation and its subsidiaries at
  December 31, 1997 and 1996, and the results of their operations and their
  cash flows for each of the three years in the period ended December 31, 1997,
  in conformity with generally accepted accounting principles. These financial
  statements are the responsibility of the Company'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
  generally accepted auditing standards 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 opinion expressed above.
