                                     PART I

Item 1.   BUSINESS
          --------

Michael Baker Corporation  ("Baker" or "the Registrant") was founded in 1940 and
organized as a Pennsylvania  corporation in 1946.  Today,  through its operating
subsidiaries and joint ventures,  Baker provides engineering,  heavy and highway
construction,  construction  management,  and operations and technical  services
worldwide.

The  Registrant is organized  into the following  five  market-focused  business
units:  Buildings,  Civil,  Energy,  Environmental  and  Transportation.   These
business  units have  coincided  with the  Registrant's  reportable  segments in
previous  years;  however,  under the  Financial  Accounting  Standards  Board's
Statement of Financial Accounting Standards No. 131, "Disclosures about Segments
of an Enterprise  and Related  Information,"  adopted by the Registrant in 1998,
two business units are required to be presented in greater detail.  Accordingly,
the  Registrant's  reportable  segments  now include the  Engineering  and Baker
Support Services, Inc. ("BSSI") divisions of the Civil unit, and the Engineering
and Construction (heavy and highway) divisions of the Transportation unit.

Information  regarding  the amounts of  revenues,  income  before  taxes,  total
assets,   capital  expenditures,   and  depreciation  and  amortization  expense
attributable to the Registrant's  reportable  segments is contained in Note 4 to
the consolidated financial statements, which are included within Exhibit 13.1 to
this Form 10-K. Such information is incorporated herein by reference.

According to the annual  listings  published in 1998 by Engineering  News Record
magazine,  Baker ranked 43rd among U.S. design firms, 18th among  transportation
design firms, 102nd among environmental  firms, 132nd among international design
firms and 150th among U.S.  construction  contractors.  Baker also ranked  104th
among  government  contractors  according  to a  listing  published  in  1998 by
Government Executive magazine. These rankings were based on 1997 revenues.

BUSINESS UNITS
- --------------
BUILDINGS.   Through  March  1999,   the  Buildings  unit  comprised  a  general
construction, construction management and design-build division and a facilities
planning  and  design  division,   that  together  or  separately   pursued  the
design-build  market.  This unit offered a variety of services including design-
build,   construction   management,   planning,   program  management,   general
contracting,  architectural and interior design,  construction  inspection,  and
constructability  reviews.  The  Buildings  unit has  completed  a wide range of
projects, such as corporate headquarters, data centers, correctional facilities,
educational facilities, airports and entertainment facilities.

Following a  significant  1998 loss on a  construction  project in the Buildings
unit,  effective in April 1999,  the Buildings unit has been  restructured  such
that  its  low-bid,   high-risk,   general  construction  activities  have  been
discontinued,  and the  Registrant  will no  longer  propose  on these  types of
construction projects. Existing low-bid, high-risk construction projects will be
completed or sold. In the future, Baker will place increased emphasis on growing
its  construction  management-for-fee  business  (for  which  the  risk  to  the
Registrant  is  lower  than  general   construction),   and  will  partner  with
contractors to pursue larger design-build contracts in the buildings market. The
Registrant  will  continue the  facilities  planning and design  division of the
Buildings unit.

CIVIL. As previously stated, the Civil unit includes two divisions,  Engineering
and  BSSI.  This  unit has  combined  Baker's  military  infrastructure  work in
planning and operations and maintenance ("O&M") to improve its ability to market
to, and serve, the U.S. Department of Defense, a significant Baker client. The
<PAGE>

Engineering  division  provides  services  which  include  surveying,   mapping,
geographic   information  systems  ("GIS"),   planning,   design,   construction
management and total program management.  The BSSI division principally provides
O&M services on U.S. military bases. The Civil unit serves clients in the fields
of  telecommunications,   water  resources,   pipelines,  emergency  management,
resources management, water/wastewater systems and facilities O&M.

ENERGY.  The Energy unit  specializes  in  providing  a full range of  technical
services for operating energy production  facilities.  The unit's  comprehensive
services consist of training, personnel recruitment, pre-operations engineering,
field operations and maintenance, mechanical equipment maintenance and logistics
management.  The  Energy  unit  serves  both major and  independent  oil and gas
producing  companies,  as well as domestic  regulated  utilities and independent
power  producers.  This unit  operates in over a dozen foreign  countries,  with
major projects in the U.S., Venezuela, Thailand and Nigeria.

ENVIRONMENTAL. The Environmental unit provides environmental, health, and safety
related  engineering  and  consulting  services  in both the public and  private
markets.  This unit provides services which include site restoration,  strategic
regulatory analysis, compliance, and advanced management systems. Clients of the
Environmental  unit include commercial  entities,  Fortune 100 companies and the
Department  of Defense,  including the U.S. Army Corps of Engineers and the U.S.
Navy. Under the Navy's Comprehensive Long-term Environmental Action Navy (CLEAN)
program, this unit has been providing  environmental support services throughout
the mid-Atlantic states, the Caribbean and Europe since 1991.

TRANSPORTATION.  Through its two divisions,  Engineering and  Construction,  the
Transportation  unit provided  planning,  design,  construction  and  operations
support services to governmental  transportation  agencies throughout the nation
in 1998. Within the Engineering division, Baker serves the professional services
segment of the market providing planning,  design,  construction  management and
inspection,  and management consulting services to municipal,  state and federal
highway, toll road and transit agencies. This division is consistently among the
twenty largest  providers of such services and enjoys a national  reputation for
its work in developing highways,  bridges,  airports,  busways and other transit
facilities.  The  Construction  division  converts  design  plans into steel and
concrete  infrastructure as a general  contractor for highways,  bridges,  track
installation,  sewer,  water and other heavy civil  construction  projects.  The
primary  customers for this division are the same as the  Engineering  division,
but more  geographically  restricted  to  Pennsylvania,  Illinois,  New York and
Florida.  

In connection with the previously mentioned  restructuring of the Buildings unit
in April 1999, the Registrant  announced that its heavy and highway construction
business will be sold. The Registrant  initiated  activities related to the sale
of the heavy and  highway  business  during the second  quarter of 1999.  Normal
construction  bidding activity will continue during the period through the sale.
Following the sale of this business,  the  Transportation  Engineering  division
will partner with other contractors to pursue selected  design-build  contracts,
which are becoming a growing project  delivery method within the  transportation
marketplace. The Registrant will continue its transportation  engineering/design
division of the  Transportation  unit, which is poised to benefit  significantly
from the U.S. government's TEA-21 legislation signed during 1998.

DOMESTIC AND FOREIGN OPERATIONS
- -------------------------------
Approximately  91%, 90% and 88% of the Registrant's total contract revenues were
derived  from work  performed  within  the  United  States  for the years  ended
December 31, 1998, 1997 and 1996,  respectively.  Further financial  information
regarding the Registrant's domestic and foreign operations is contained in Notes
4 and 10 to the  consolidated  financial  statements,  which are included within
Exhibit  13.1 to this Form 10-K.  Such  information  is  incorporated  herein by
reference. Of the Registrant's domestic  revenues, the  majority  comprises
<PAGE>

engineering and construction  work performed in the Northeast region of the U.S.
The Registrant's  international  revenues are derived  primarily from its Energy
unit.

FUNDED AND UNFUNDED BACKLOG
- ---------------------------
The  Registrant's  funded  backlog,  which comprises that portion of uncompleted
work  represented  by signed  contracts and for which the  procuring  agency has
appropriated  and allocated  the funds to pay for the work,  was $448 million at
December 31, 1998 and $393 million at December 31, 1997.  Total  backlog,  which
incrementally  includes  that  portion of contract  value for which  options are
still to be exercised (unfunded backlog),  was $735 million at December 31, 1998
and $649  million at December  31,  1997.  With  reference  to the  Registrant's
restructuring  announced in April 1999, funded backlog related to the businesses
that will be continued by the Registrant was $300 million and $252 million,  and
total backlog was $587 million and $508  million,  as of year-end 1998 and 1997,
respectively.

There is not necessarily a direct correlation  between the foregoing figures and
the  Registrant's  annual total  contract  revenues.  In the case of  multi-year
contracts,  total contract revenues are spread over several years and correspond
to the timing of the contract  rather than the  Registrant's  fiscal year.  Many
multi-year contracts, particularly with agencies of the U.S. government, provide
for optional renewals on the part of the customer.  The Registrant's  experience
has been that these optional contract  renewals,  which are included in unfunded
backlog,  have generally  been  exercised.  Funded backlog  generally is highest
during the last quarter of the Registrant's fiscal year because that corresponds
to the first quarter of the U.S.  government's  fiscal year,  which is when many
government contract renewals occur.

SIGNIFICANT CUSTOMERS
- ---------------------
Contracts with various  branches of the U.S.  government  accounted for 27%, 24%
and 23% of the Registrant's total contract revenues for the years ended December
31, 1998, 1997 and 1996, respectively. In addition, an individual Buildings unit
construction  contract with Universal City  Development  Partners  accounted for
11.5% of the Registrant's  total contract  revenues in 1998.  Further  financial
information  regarding this contract is contained in Note 2 to the  consolidated
financial statements,  which are included within Exhibit 13.1 to this Form 10-K.
Such  information is incorporated  herein by reference.  No individual  contract
accounted for more than 10% of the Registrant's  total contract revenues in 1997
or 1996.

COMPETITIVE CONDITIONS
- ----------------------
The  Registrant's  business is highly  competitive with respect to all principal
services it offers.  Baker competes with numerous firms that provide some or all
of the services  provided by the Registrant.  The competitive  conditions in the
Registrant's  businesses  relate to the nature of the contracts  being  pursued.
Public-sector  contracts,  consisting mostly of contracts with federal and state
governmental  entities,  are generally  awarded  through a competitive  process,
subject to the contractors'  qualifications  and experience.  The Baker business
units employ extensive cost estimating,  scheduling and other techniques for the
preparation  of  these  competitive  bids.  Private-sector  contractors  compete
primarily on the bases of  qualifications,  quality of performance  and price of
services.  Such  private-sector  contracts are generally awarded on a negotiated
basis.

The  Registrant  believes  that the  principal  competitive  factors (in various
orders of importance) in the areas of services it offers are quality of service,
reputation, experience, technical proficiency and cost of service. The
<PAGE>

Registrant  believes  that it is  well  positioned  to  compete  effectively  by
emphasizing its full range of professional services.

SEASONALITY
- -----------
Based upon the Registrant's  experience,  total contract revenues and net income
from  engineering  and  construction-related  services  tend to be lower for the
first quarter than for the remaining quarters due to winter weather  conditions,
particularly  for projects in the  Northeast  and Midwest  regions of the United
States.

PERSONNEL
- ---------
At December 31, 1998,  the  Registrant  employed  approximately  3,824  persons,
broken down by business unit as follows:

              Buildings unit-287                  Environmental unit-159
              Civil unit-1,472                    Transportation unit-1,026
              Energy unit-841                     Corporate staff-39

The  Registrant's  employees  are not  represented  by  labor  unions,  with the
exception  of  its  construction   personnel  which  are  generally  covered  by
collective  bargaining  agreements,  as are certain BSSI  employees in the Civil
unit.  The  majority  of  current  construction-related   collective  bargaining
agreements  do not  expire  until  the year  2005.  During  1999,  several  BSSI
collective  bargaining  agreements  are  scheduled  for  renegotiation,  but  no
significant  issues  are  expected.  Currently,  the  Registrant  considers  its
relationships with labor unions to be good.


Item 2.   PROPERTIES
          ----------

The principal  offices of the Registrant are located at the Airport Office Park,
410 and 420 Rouser Road, Coraopolis,  Pennsylvania 15108, at which approximately
165,000 square feet of office space is leased for use by the Registrant's Civil,
Buildings,  Environmental and  Transportation  units and, to a lesser extent, by
its corporate  staff.  The Registrant  owns a 75,000 square foot office building
located in Beaver County, Pennsylvania, which is situated on a 175 acre site and
utilized by the  Registrant's  Civil unit. The Beaver  building and property are
currently for sale.  Upon any such sale, the  Registrant  would expect to either
continue  leasing  this  building  from the new owner or relocate  the  affected
employees to the Coraopolis area.

The  Registrant  leases an aggregate  of  approximately  466,000  square feet of
office-related floor space, including its principal offices. The space leased by

Item 3.   LEGAL PROCEEDINGS 
          -----------------

The  Registrant  has  been  named  as  a  defendant  or  co-defendant  in  legal
proceedings wherein  substantial  damages are claimed.  Such proceedings are not
uncommon to the Registrant's business.  After consultations with counsel, except
as discussed  below,  management  believes that the  Registrant  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 Registrant.

The Registrant currently has two significant legal proceedings outstanding.  The
more  significant one relates to a contract for the construction of the CityWalk
project at the Universal  Studios theme park in Orlando,  Florida  between Baker
Mellon Stuart  Construction,  Inc. ("BMSCI"),  a wholly-owned  subsidiary of the
Registrant,   and  Universal  City  Development  Partners  ("UCDP").  BMSCI  was
providing  project-related  construction  services  to UCDP under the  contract.
During BMSCI's performance under the contract,  which began in 1997, the project
suffered delays due to substantial  changes in the design of the project and the
related drawings.

On March 5, 1999, UCDP terminated BMSCI's right to proceed with the project work
by alleging  default.  UCDP has also  notified  BMSCI of UCDP claims for damages
resulting  from the alleged  default,  including the cost to complete or correct
the work,  additional  maintenance or operation costs, and alleged lost revenues
or other damages.  UCDP simultaneously filed a lawsuit for breach of contract in
the Federal District Court in the Middle District of Florida ("Federal  Court").
The Registrant  will answer the complaint,  or file a motion to dismiss or other
responsive  pleading  in the  action.  On March 8, 1999,  BMSCI  filed a lawsuit
against  UCDP in the  Circuit  Court for the Ninth  Judicial  Circuit in and for
Orange County,  Florida  ("State Court")  alleging breach of contract,  wrongful
termination  and other  counts and seeking  damages,  interest,  court costs and
other  relief,  including  potential  counterclaims.  Discovery has not begun in
either case,  although the parties are  cooperating  in the initial  exchange of
documents  for the cases.  No other  scheduling  order or other case  management
documents have been filed.

<PAGE>

In addition, two of BMSCI's subcontractors have also filed suit against BMSCI in
connection  with the  project.  On November 24, 1998,  ADF  International  Inc.,
BMSCI's subcontractor for structural  steel/miscellaneous  metals, filed suit in
Federal  Court  against  BMSCI and its  surety  seeking  damages  for  breach of
contract  relating  to the  project.  BMSCI and its  surety  have  answered  the
complaint (and amended complaint) and BMSCI has filed a counterclaim.  Discovery
in the matter is  beginning,  and no trial date has been set.  On  February  10,
1999,  Martin K. Eby  Construction  Company,  Inc.,  BMSCI's  subcontractor  for
foundations,  also  filed  suit in Federal  Court  against  BMSCI and its surety
seeking  damages for breach of contract  relating to the project.  BMSCI and its
surety have answered the complaint. Discovery in the matter is beginning, and no
trial date has been set. BMSCI has held discussions with both ADF  International
Inc. and Martin K. Eby  Construction  Company,  Inc.  with the intent of jointly
pursuing the  subcontractors'  claims and those of BMSCI against UCDP, which may
be ultimately responsible for the claims arising from the project.

Additional  claims may be filed in  connection  with this matter.  Baker and its
counsel believe that BMSCI has valid claims against UCDP and its  subcontractors
and  intends  to  defend  these  claims  vigorously.   However,  an  unfavorable
resolution  of  these  matters  could  have a  material  adverse  effect  on the
Registrant's  consolidated  financial  position,  results of operations and cash
flow.

The other  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 Registrant and one of its
wholly-owned  subsidiaries,  that asserts breach of contract and alleges damages
of $13 million. The Registrant, which was not a party to the contract underlying
the  lawsuit,  contends  that  there  is no  jurisdiction  with  respect  to the
Registrant and that it cannot be held liable for any conduct of the  subsidiary.
Both the Registrant and the subsidiary are contesting  liability issues and have
filed cross-claims and third-party claims against the other entities involved in
the project.

Item 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
          ---------------------------------------------------

No matters were submitted to a vote of the Registrant's  security holders during

operations  is set  forth  in  the  "Management's  Discussion  and  Analysis  of

Item 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
          ----------------------------------------------------------

Based on the  Registrant's  current and long-term  debt  balances  totaling $4.0
million at December 31, 1998,  Baker has no material  exposure to interest  rate
risk. Less than 1% of the Registrant's  total assets and total contract revenues
as of and for the year  ended  December  31,  1998 were  denominated  in British
Pounds Sterling; accordingly, the Registrant has no material exposure to foreign
currency  exchange  risk.  These  materiality   assessments  are  based  on  the
assumption that either the interest rates or the foreign currency exchange rates
could  change  unfavorably  by 10%.  Based  on the  nature  of the  Registrant's
business,  it has no exposure to commodity  price risk. In  accordance  with the
foregoing, the Registrant has no interest rate swap or exchange agreements,  nor
does it have any foreign currency exchange contracts.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the  Securities  Exchange Act of 1934 (the "1934 Act") requires
the Registrant's directors and executive officers, and persons who own more than
ten percent of a registered class of the Registrant's equity securities, to file
with the Securities and Exchange  Commission (the "Commission")  initial reports
of  ownership  and  reports of changes in  ownership  of Common  Stock and other
equity  securities  of the  Registrant.  Such persons are required by Commission
regulations  to furnish the  Registrant  with copies of all Section  16(a) forms
which they file.  The  Registrant  believes  that all such  filing  requirements
applicable  to its executive  officers and directors  were complied with in 1998
except that a Form 5 filed by Philip A.  Shucet,  an officer of the  Registrant,
was deemed to be late because it inadvertently omitted certain information.

      vest in four equal annual installments beginning on the date of grant. The
      dollar amounts under the potential realizable value columns are the result
      of  calculations  at  assumed  annually  compounded  rates of stock  price
      appreciation  over the ten-year life of the options in accordance with the

and Exchange Act of 1934, as amended,  that might  incorporate  future  filings,
including this Form 10-K in whole or in part, the following report and the Stock
Performance Graphs shall not be incorporated by reference into any such filings.

Report of the Compensation Committee

Introduction

Decisions regarding  compensation of the Registrant's  executives  generally are
made by a three-member Compensation Committee of the Board.

All decisions of the  Compensation  Committee  relating to  compensation  of the
Registrant's executive officers are reviewed and approved by the full Board. Set
forth below is a report  submitted by Messrs.  Larson,  Murray and Weis in their
capacity as the  Board's  Compensation  Committee  addressing  the  Registrant's
compensation  policies  for  1998 as they  affected  executive  officers  of the
Registrant,  including Mr. Homan, the President and Chief Executive Officer, and
Messrs.  Fusilli,  Hayward,  Wiley and White, the four executive  officers other
than Mr. Homan who were, for 1998, the  Registrant's  most highly paid executive
officers.

Compensation Philosophy

The Registrant  applies a consistent  philosophy toward  compensation based upon
the following objectives: (i) to attract and retain executive officers and other
key employees of outstanding  ability,  and to motivate all employees to perform
to the full extent of their  abilities;  (ii) to ensure that pay is  competitive
<PAGE>
with other  leading  companies  in the  Registrant's  industry;  (iii) to reward
executive officers for corporate, group and individual performance;  and (iv) to
ensure  that total  compensation  to the  executive  officers  as a group is not
disproportionate when compared to the Registrant's total employee population.

Compensation

The  Compensation  Committee  retains  the  services  of  Hewitt  Associates,  a
compensation  consulting  firm,  to assist  the  Committee  in  connection  with
performance  of its duties.  Hewitt  Associates  provides  ongoing advice to the
Committee with respect to the  reasonableness  of compensation paid to executive
officers of the Registrant.

The  Registrant  applies a  compensation  program  consisting of base salary and
annual  incentive  compensation.  In determining Mr. Homan's salary as President
and Chief Executive Officer and the remaining  executive officers' base salaries
for  1998,  the  Compensation   Committee   reviewed  the  relationship  of  his
compensation  to that of other  executive  officers of the  Registrant  and, the
Registrant's current and projected growth and profitability performance.

Incentive  compensation  for Mr.  Homan  and the  other  executive  officers  is
determined based on the achievement of such predetermined  corporate performance
goals as  profitability  and  earnings  per share.  Each such  officer's  annual
performance is measured by reviewing  contribution  to overhead and profit,  new
work added,  cash flow return on investment,  human  resources  development  and
continuous improvement management goals.

The Chief Executive  Officer  recommends to the  Compensation  Committee  salary
adjustments for executive officers.  The committee reviews these recommendations
in light of the above  factors and with  reference to the Hewitt  Report and the
executive  salary studies  described above. A final comparison is made to verify
that  the  total  percentage  increase  in  compensation  paid to the  executive
officers  as  a  group  is  not  disproportionate  to  the  percentage  increase
applicable to other Registrant employee groups.

All  executive  employees  participate  in  an  annual  incentive  program.  The
components  of the plan are based upon  corporate  and  individual  performance.
Measures of corporate  performance  may include,  but are not limited to, one or
more financial measures such as earnings per share and profitability. Individual
performance is based on the  performance  rating  received as part of the annual
Performance  Management Process. The Performance Management Process is a program
which  emphasizes  performance  planning   (management/employee  goal  setting),
progress reviews and management feedback to employees. Primary objectives of the
program are to enhance the professional  development of the individual  employee
and to align  individual  performance  goals with those of the  Registrant.  The
rating is based upon factors  agreed to by the Chief  Executive  Officer and the
individual executive employees.

1995 Stock Incentive Plan

On December 15, 1994, the Board of Directors  approved the 1995 Stock  Incentive
Plan (the "Option  Plan"),  which was approved by the  shareholders  at the 1995
Annual  Meeting  and  provides  long-term  incentive  compensation  to  eligible
employees.  The Compensation  Committee retains the services of Buck Consultants
to assist the Committee in  evaluating  the Option Plan relative to practices of
other  publicly-traded  companies  engaging  in one or more  lines  of  business
comparable to those of the Registrant.

Stock  options  are  awarded  based  on the  Compensation  Committee's  judgment
concerning the position and  responsibilities  of the employee being considered,
the nature and value of his or her services,  his or her current contribution to
the success of the  Registrant,  and any other  factors  which the  Compensation
Committee may deem relevant. Stock option awards tie the interests of employees
to the  long-term  performance  of the  Registrant,  and  provide  an  effective
<PAGE>
incentive for employees to create shareholder value over the long term since the
full  benefit  of  the  compensation   package  cannot  be  realized  unless  an
appreciation in the Registrant's stock price occurs over a number of years.

In 1998, the Compensation  Committee  reviewed the Option Plan and, based on its
review, recommended to the Board of Directors that the Option Plan be amended to
increase by 1,000,000 the number of shares  available for grants  thereunder and
to increase the maximum  number of shares as to which  options may be granted to
any one employee  during any calendar  year from 30,000 to 100,000  shares.  The
Board of  Directors  approved  the  amendment  on  February  27,  1998,  and the
Shareholders  adopted the amendment on April 22, 1998 at the 1998 Annual Meeting
of  Shareholders.   The  Compensation  Committee  believes  these  changes  were
desirable in order to ensure that there are sufficient  options  available under
the Option Plan to continue to motivate and reward  employees and to ensure that
the grants are significant enough to provide meaningful inducement and reward to
key employees.

In addition, on April 23, 1998, the Compensation Committee adopted a proposal to
award a one-time  grant of stock  options to certain  employees,  the vesting of
which will be based upon the  Registrant  achieving  earnings for the year ended
December  31, 2000 (the  "Fiscal  Year 2000") equal to or in excess of $1.25 per
share of Common Stock (the "Vision 2000 Options").  The Vision 2000 Options will
vest and may be exercisable  immediately upon the  determination of the Board of
Directors,  based on the audited  financial  results of the  Registrant  for the
Fiscal Year 2000,  that the Registrant  has achieved  earnings of at least $1.25
per share for the Fiscal Year 2000.  In the event that the  Registrant  does not
achieve such  earnings,  the Vision 2000 Options will become  exercisable  eight
years from the date of the grant.  The exercise price of the Vision 2000 Options
will be the fair market value of the Common Stock on the date of the grant.  The
Vision 2000 Options were granted on April 23, 1998,  and have an exercise  price
equal to $10.125.

1996 Nonemployee Directors' Stock Incentive Plan

On February 27,  1996,  the Board of  Directors  approved  the 1996  Nonemployee
Directors'  Stock Incentive Plan,  which was approved by the shareholders at the
1996 Annual  Meeting.  This plan provides  long-term  incentive  compensation to
eligible  directors.  Under this plan, each member of the Board of Directors who
is not an employee of the Registrant or any of its  subsidiaries  is granted 500
restricted  shares and an option to purchase 1,000 shares of Common Stock on the
first business day following each Annual Meeting of Shareholders.

This report is submitted by the Compensation Committee of the Registrant's Board
of Directors.

Compensation Committee Interlocks and Insider Participants

The members of the  Compensation  Committee in 1998,  Thomas D. Larson,  John E.
Murray,  Jr. and Konrad M. Weis,  are  nonemployee  directors.  During 1998,  no
executive officer of the Registrant served on a compensation committee (or other
board committee performing equivalent functions) or on the board of directors of
any entity  (other  than the  Registrant's  Board of  Directors)  related to any
member of the Registrant's Board of Directors.

Stock Performance Graph

The graph below compares for the five-year period commencing  December 31, 1993,
the yearly percentage  change in the cumulative total shareholder  return on the
Registrant's  Common Stock with the cumulative total return of the S&P 500 Stock
Index,  the  Russell  2000 Stock Index and with a peer group  identified  by the
Registrant to best approximate the Registrant's diverse business groups.

The peer group was selected to include publicly-traded companies engaging in one
or more of the  Registrant's  lines of business:  engineering,  construction and
operations and maintenance.

The peer group consists of the following companies:  Aqua Alliance,  Inc. (f/k/a
Air and Water Technologies Corp.),  Dames & Moore Group,  Granite  Construction,
Inc.,  Harding Lawson Associates Group,  Inc., ICF Kaiser  International,  Inc.,
Jacobs Engineering Group,  Inc.,  Morrison Knudsen Corp.,  Perini Corp., Stone &
Webster,  Inc., STV Group,  Inc., Tetra Tech, Inc., Turner Corp., URS Corp., Roy
F. Weston, Inc. [Note: Guy F. Atkinson Registrant of California, a member of the
peer group in previous years, ceased operations during 1998.]

The following five year total shareholder return chart compares the Registrant's
total shareholder return on the Registrant's  Common Stock with that of the peer
group used for the year ended December 31, 1998.

(1)  Under regulations of the Securities and Exchange  Commission,  a person who
     has or shares  voting or  investment  power with  respect to a security  is
     considered a beneficial owner of the security. Voting power is the power to
     vote or direct the voting of shares,  and investment  power is the power to
     dispose of or direct the disposition of shares.  Unless otherwise indicated
     in the other  footnotes  below,  each person has sole voting power and sole
     investment  power as to all  shares  listed  opposite  his  name.  The ESOP
     requires  the  trustee to vote the shares  held by the trust in  accordance
     with the instructions  from the ESOP  participants for all shares allocated
     to  such  participants'  accounts.  Allocated  shares  for  which  no  such
     instructions  are given and  shares  not  allocated  to the  account of any
     employee are voted by the trustee in the same  proportion  as the votes for
     which  participant  instructions  are given. In the case of a tender offer,
     allocated  shares  for  which no  instructions  are  given are not voted or
     tendered, and shares not allocated to the account of any employee are voted
     by the trustee in the same  proportion  as the votes for which  participant
     instructions are given.

(2)  Shares held as a group by Goldman  Sachs & Co. and the Goldman Sachs Group,
     L.P., each of which disclaim beneficial  ownership of all such shares. This

4.3  INDIVIDUAL PERFORMANCE REVIEW CRITERIA

In order for an  individual  to be  eligible  for any  portion  of an  incentive
compensation  payout, they must receive at least a "3.0" or "Meets Expectations"
on the performance review form. This change is made to further reinforce Baker's
cultural strategy which embraces the importance of goal attainment and how those
goals are attained.  As in last year's plan, an individual  must receive a "2.6"
or  greater  on the  performance  plan in order to be  eligible  for the  payout
related to individual performance goals.

4.4  BUSINESS UNIT PERFORMANCE:

Business Unit  performance  shall be reflected in the final award based upon the
Business  Unit's  Contribution to Corporate  Overhead and Profit.  The Incentive
Compensation  Committee shall establish and approve  Competent,  Commendable and
Outstanding  Contribution  goals specific to each Business Unit at the beginning
of the Plan year.  The  Competent  goal shall serve as a Threshold  target which
must be met in order  for  Business  Unit  Managers  and  those  having  overall
Business Unit accountability to be eligible to receive an incentive payout based
upon their individual  performance plans. In addition,  the Competent goal shall
serve as a Threshold  target which must be met in order for all Business Segment
participants  to receive a payout  based upon  Business  Unit  performance.  For
Business  Segment  participants,  the  incentive  compensation  award related to
Business  Unit  performance  is based upon "step"  accomplishment  of Competent,
Commendable, or Outstanding goals and is not to be pro-rated.

Any Business Unit with an objective of a positive contribution  performance (net
income before tax plus corporate  overhead) which results in a year-end negative
contribution,  may  be  eligible  for  the  portion  of  incentive  compensation
dependent  on overall  corporate  earnings  per share  performance,  pending CEO
approval as advised by the Incentive Compensation  Committee.  Any Business Unit
with an objective of a negative contribution  performance (net income before tax
plus corporate overhead) which results in a year-end more negative contribution,
may be eligible for the portion of incentive  compensation  dependent on overall
corporate earnings per share performance, pending CEO approval as advised by the
Incentive  Compensation  Committee.  Factors to be taken into  consideration may
include the amount of deviation from  objective,  impact of the  contribution of
the Business Unit to the Corporation and any extraordinary issues.


<PAGE>



Any Business Unit with an objective of a negative  contribution which results in
a year-end  more  favorable  performance,  will be  eligible  for the portion of
incentive compensation dependent on overall corporate performance.

4.5  BUSINESS SEGMENT PERFORMANCE:

Business Segment  performance shall be reflected in the final award based on the
Business Segment's  Contribution to Corporate Overhead and Profit. The Incentive
Compensation  Committee  shall approve  Competent,  Commendable  and Outstanding
Contribution  goals  specific to each  Business  Segment at the beginning of the
Plan year.  The Competent  goal shall serve as a Threshold  target which must be
met in order for  participants  within the  Segment to be eligible to receive an
incentive payout based upon individual performance plans.

Any Business  Segment with an objective of a positive  contribution  performance
(net income  before tax plus  corporate  overhead)  which  results in a year-end
negative contribution, may be eligible for the portion of incentive compensation
dependent on overall corporate  earnings per share  performance  and/or Business
Unit Contribution to Overhead and Profit, pending CEO approval as advised by the
Incentive  Compensation  Committee.  Any Business Segment with an objective of a
negative  contribution   performance  (net  income  before  tax  plus  corporate
overhead)  which  results  in a  year-end  more  negative  contribution,  may be
eligible  for  the  portion  of  incentive  compensation  dependent  on  overall
corporate  earnings per share  performance  and/or Business Unit Contribution to
Overhead  and  Profit,   pending  CEO  approval  as  advised  by  the  Incentive
Compensation  Committee.  Any  Business  Segment with an objective of a negative
contribution  which results in a year-end more  favorable  performance,  will be
eligible  for  the  portion  of  incentive  compensation  dependent  on  overall
corporate performance and Business Unit Contribution to Overhead and Profit.

4.6  INDIVIDUAL PERFORMANCE:

Individual  performance  shall be  reflected  in the  final  award  based on the
performance rating assigned to an Employee as part of the Performance Management
Process and is based upon a number of factors  established by the  participant's
manager(s) at the beginning of the Plan Year.

</TABLE>


The above guidelines are recommended but are not prescriptive,  particularly for
functional positions (e.g.:  finance,  marketing,  human resources).  Individual
performance measures for incentive compensation participants are to be developed
jointly  with  the  employee's  immediate  supervisor,  be  consistent  with the
participant's   respective  job   responsibilities,   and  be  included  on  the
participant's  performance  plan.  Participants  may have plans  that  relate to
corporate, unit or segment. The performance plans are to be submitted to the CEO
by the Business Unit head or Functional  Unit head by the designated time in the
Plan year. For  individuals who become  eligible for  participation  in the Plan
during the course of the year, a completed  performance  plan is to be submitted
within four weeks of the individual becoming eligible for participation.


<PAGE>



At the end of the Plan Year, incentive compensation  participants' managers will
determine the level of performance accomplished by the participant.  Participant
performance  which  does not  meet or  exceed  the  Meets  Expectations-On  Plan
Performance-3  level on a specific  goal will result in no incentive  payout for
that  specific  performance  goal.  Once  performance  has  exceeded  the  Meets
Expectations-On  Plan  Performance-3  level on a specific  financial  goal,  any
performance beyond the 3 level will result in a pro-rated  weighted  calculation
of the incremental incentive  compensation earned by the participant,  until the
maximum level 5 performance is achieved. Once performance has exceeded the Meets
Expectations-On  Plan  Performance-3  level  for  major  performance  areas  for
functional unit employees,  any performance  beyond the 3 level will result in a
pro-rated  calculation,  in increments of .5 (e.g.:  3.5, 4.0, 4.5 etc.), of the
incremental incentive compensation earned by the participant,  until the maximum
level 5 performance is achieved.

Payout for participants  meeting  individual  performance  goals will occur when
Business Unit or Business Segment (as applicable)  operating profit accomplishes
threshold  performance  indicated in each Business Unit's or Business  Segment's
Performance Plan (after all individual incentives have been paid).

The specific  accomplishments  associated with these goals are to be recorded on
each  participant's  annual Performance Plan at the end of the Plan Year as part
of the overall performance evaluation.

4.7     DISCRETIONARY AWARDS:

In addition to individual  performance  incentives,  a discretionary pool may be
created  within  Corporate and within each Business  Unit to  selectively  award
those  individuals  who  have  exceeded  expected  performance.  Guidelines  for
discretionary  awards are indicated  within the  Corporate  and Business  Units'
Incentive  Compensation  Plan  Summary  in  the  attachments.   Functional  Unit
discretionary  awards are to be selected by the CEO with the  concurrence of the
Incentive Compensation  Committee.  Business Unit discretionary awards are to be
selected  by  the  Executive  Vice  President  of the  Business  Unit  with  the
concurrence of the Incentive Compensation Committee.


ARTICLE V

PAYMENT OF AWARDS

5.1  PAYMENT OF AWARDS:

At the end of each Plan Year,  the CEO shall  report the overall  Corporate  and
individual  performance  levels to the  Compensation  Committee  of the Board of
Directors, who shall then approve the payment of awards.

The incentive compensation earned as a result of the Company achieving corporate
profitability  goals and through the  achievement  of  Business  Unit,  Business
Segment and individual goals, will be paid in cash no later than March 15 of the
year after which it was earned.
<PAGE>



5.2  PLAN FUNDING:

Accrual for the Incentive  Compensation Plan will be established annually by the
Committee,  subject to the  approval of the CEO.  The  approved  accrual for the
Incentive  Compensation  Plan shall pre-fund the amounts  available to be earned
for incentive  compensation  distributions.  Any forfeitures associated with the
termination of those in the incentive  compensation  plan prior to year-end will
be allocated toward the funding of the incentive pool for the following year. In
addition,  if the  incentive  pool is not paid out in full  because of  Business
Unit,  Business  Segment or participants'  failure to achieve goals  established
under the Plan or the Performance Management Process, the unearned portion would
be allocated toward the funding of the incentive pool for the following year.

Any excess pre-funding accrual based upon corporate goals which are not met and,
therefore,  not earned by  Incentive  Compensation  Plan  participants,  will be
removed from expense.


ARTICLE VI

CHANGE IN CONTROL


6.1  CHANGE IN CONTROL:

In the  event of a Change  in  Control  of the  Company,  as  defined  below,  a
Participant  shall be  entitled  to,  for the Plan Year in which  the  Change of
Control occurs, the award determined using:

    (i)   The Participant's actual Base Salary rate in effect on the date of the
          Change in Control,

    (ii)  Actual Corporate performance results to the date of Change in Control,
          and

    (iii) Participant's Individual Performance results.

The Committee as  constituted  immediately  prior to the Change in Control shall
determine how actual  Corporate  performance  should be measured for purposes of
the award calculation in 6.1. The Committee's  determination shall be conclusive
and final.

Awards  and  any  previously  accrued  awards  shall  be  paid  in  cash  to the
Participant  promptly  following  any  discontinuance  of the Plan on or after a
Change of Control.
<PAGE>



6.2  DEFINITION OF CHANGE IN CONTROL:

A "Change in Control"  will be deemed to have  occurred on the first to occur of
the following:

(a)  The  Company  acquires  actual  knowledge  that any  Person  other than the
     Company, a Subsidiary,  the Company's Stock Ownership Plan and Trust or any
     employee  benefit  plan(s)  sponsored  by  the  Company  has  acquired  the
     Beneficial Ownership,  directly or indirectly, of securities of the Company
     entitling such Person to 20% or more of the Voting Power of the Company;

(b)  A Tender Offer is made to acquire  securities of the Company  entitling the
     holders thereof to 20% or more of the Voting Power of the Company; or

(c)  A solicitation  subject to Rule 14a-11 under the 1934 Act (or any successor
     Rule)  relating to the election or removal of 50% or more of the members of
     any class of the Board  shall be made by any person  other than the Company
     or less than 51% of the members of the Board shall be Continuing Directors;
     or

(d)  The  shareholders  of the Company  shall  approve a merger,  consolidation,
     share  exchange,  division  or sale or other  disposition  of assets of the
     Company as a result of which the  shareholders  of the Company  immediately
     prior  to  such  transaction  shall  not  hold,   directly  or  indirectly,
     immediately  following  such  transaction a majority of the Voting Power of
     (i) in the case of a merger or  consolidation,  the  surviving or resulting
     corporation,   (ii)  in  the  case  of  a  share  exchange,  the  acquiring
     corporation  or  (iii)  in  the  case  of a  division  or a sale  or  other
     disposition of assets, each surviving,  resulting or acquiring  corporation
     which,  immediately  following the transaction,  holds more than 10% of the
     consolidated assets of the Company immediately prior to the transaction.

The  term  "person"  shall  mean  and  include  any   individual,   corporation,
partnership,  company,  association  or other  "person," as such term is used in
Section  14(d) of the  Exchange  Act,  other than the  Company  or any  employee
benefit plans sponsored by the Company.

"Continuing Directors" shall mean a director of the Company who either (a) was a
director  of the  Company  on  the  effective  date  of  the  Plan  or (b) is an
individual  whose  election,  or nomination  for election,  as a director of the
Company was  approved by a vote of at least  two-thirds  of the  directors  then
still in office who were Continuing  Directors  (other than an individual  whose
initial  assumption  of office  is in  connection  with an actual or  threatened
election  contest  relating to the election of  directors  of the Company  which
would be subject to Rule 14a-11 under the 1934 Act, or any successor Rule).

ARTICLE VII

MISCELLANEOUS PROVISIONS

7.1 NON-TRANSFERABILITY:

No right of  interest of any  Participant  in this Plan shall be  assignable  or
transferable,  or  subject  to  any  lien,  directly,  by  operation  of  law or
otherwise,  including  execution,  levy,  garnishment,  attachment,  pledge, and
bankruptcy.

time to time,  may  modify  or  amend,  in whole  or in part,  any or all  other
provisions of this Plan, or suspend or terminate it entirely;  provided, that no
such modification, amendment, suspension, or termination may reduce the right of
a  Participant  (or  his  beneficiary  as  the  case  may  be) to a  payment  or
distribution in accordance with the provisions  contained in this Plan or change
to the  detriment of a  Participant  of any  potential  rights in that Plan Year

settlement thereof,  with the Company's approval, or paid by him in satisfaction

                            MICHAEL BAKER CORPORATION
                           1995 STOCK INCENTIVE PLAN,
                       AS AMENDED EFFECTIVE APRIL 23, 1998

    The purposes of the 1995 Stock  Incentive Plan (the "Plan") are to encourage
eligible  employees of Michael Baker  Corporation  (the  "Corporation")  and its
subsidiaries  to  increase  their  efforts  to make  the  Corporation  and  each
Subsidiary  more  successful,  to  provide  an  additional  inducement  for such
employees  to remain  with the  Corporation  or a  Subsidiary,  to  reward  such
employees by providing an opportunity to acquire shares of the Common Stock, par
value $1.00 per share,  of the  Corporation  (the  "Common  Stock") on favorable
terms and to provide a means  through  which the  Corporation  may attract  able
persons to enter the employ of the Corporation or one of its  Subsidiaries.  For
the purposes of the Plan,  the term  "Subsidiary"  means any  Corporation  in an
unbroken chain of corporations  beginning with the  Corporation,  if each of the
corporations  other than the last  corporation  in the unbroken chain owns stock
possessing  at least fifty percent  (50%) or more of the total  combined  voting
power of all classes of stock in one of the other corporations in the chain.

                                    SECTION 1
                                 ADMINISTRATION

    The Plan  shall be  administered  by a  committee  (the  "Committee")  to be
appointed  from  time to time  by the  Corporation's  Board  of  Directors  (the
"Board")  which  hereafter  shall  consist  of not less than two  members of the
Board,  each of whom shall on January 1, 1995, or at the time of  appointment to
the Committee  subsequent thereto and at all times during service as a member of
the Committee be (i) a "disinterested person" as that term is then defined under
Rule 16b-3 under the  Securities  Exchange  Act of 1934,  as amended  (the "1934
Act") or any  successor  rule  and  (ii) an  "outside  director"  under  Section
162(m)(4)(c) of the Internal Revenue Code of 1986 (the "Code"), or any successor
provision.

    The Committee shall interpret the Plan and prescribe such rules, regulations
and procedures in connection  with the operation of the Plan as it shall deem to
be necessary and advisable for the  administration  of the Plan  consistent with
the purposes of the Plan. All questions of interpretation and application of the
Plan, or as to grants under the Plan,  shall be subject to the  determination of
the Committee, which shall be final and binding.

    The Committee shall keep records of action taken at its meetings. A majority
of the  Committee  shall  constitute a quorum at any meeting,  and the acts of a
majority of the members present at any meeting at which a quorum is present,  or
acts approved in writing by all the members of the Committees, shall be the acts
of the Committee.

                                    SECTION 2
                                   ELIGIBILITY

    Those key employees of the Corporation or any Subsidiary (including, but not
limited to,  covered  employees as defined in Section  162(m)(3) of the Code, or
any successor provision) who share responsibility for the management,  growth or
protection  of the  business  of the  Corporation  or any  Subsidiary  shall  be
eligible to be granted stock options as described herein.

    Subject to the  provisions of the Plan,  the  Committee  shall have full and
final authority,  in its discretion,  to grant stock options as described herein
and to determine the employees to whom any such grant shall be made and the


<PAGE>



number of shares to be covered  thereby.  In determining  the eligibility of any
employee,  as well as in determining  the number of shares covered by each grant
of  a  stock  option,   the  Committee  shall  consider  the  position  and  the
responsibilities  of the employee being considered,  the nature and value to the
Corporation  or a Subsidiary of his or her services,  his or her present  and/or
potential  contribution  to the success of the  Corporation  or a Subsidiary and
such other factors as the Committee may deem relevant.

                                    SECTION 3
                         SHARES AVAILABLE UNDER THE PLAN

    The  aggregate  number of shares of the Common Stock which may be issued and
as to which  grants of stock  options  may be made  under the Plan is  1,500,000
shares, subject to adjustment and substitution as set forth in Section 6. If any
stock option  granted under the Plan is canceled by mutual consent or terminates
or expires for any reason  without  having been exercised in full, the number of
shares  subject  thereto  shall again be available  for purposes of the Plan. If
shares  of  Common  Stock  are  forfeited  to the  Corporation  pursuant  to the
restrictions  applicable,  the shares so forfeited  shall not again be available
for purposes of the Plan unless during the period such shares were  outstanding,
the grantee  received no dividends or other  "benefits of  ownership"  from such
shares.  The shares which may be issued under the Plan may be either  authorized
but unissued  shares or treasury  shares or partly each,  as shall be determined
from time to time by the Board.

                                    SECTION 4
                             GRANT OF STOCK OPTIONS

    The Committee shall have authority,  in its discretion,  to grant "incentive
stock options" pursuant to Section 422 of the Code, to grant "nonstatutory stock
options" (i.e.,  stock options which do not qualify under Sections 422 or 423 of
the Code) or to grant both types of stock options (but not in tandem).

    During the  duration of the Plan,  the maximum  number of shares as to which
stock  options  may be granted and as to which  shares may be awarded  under the
Plan to any one employee during any calendar year is 100,000 shares,  subject to
adjustment and  substitution as set forth in Section 6. For the purposes of this
limitation,  any  adjustment  or  substitution  made  pursuant to Section 6 with
respect  to the  maximum  number of shares set forth in the  preceding  sentence
shall  also  be made  with  respect  to any  shares  subject  to  stock  options
previously  granted  under the plan to such  employee  during the same  calendar
year.

    Notwithstanding  any other  provision  contained in the Plan or in any stock
option  agreement  referred  to in  Section  5(F) but  subject  to the  possible
exercise of the Committee's discretion contemplated in the last sentence of this
Section 4, the aggregate  fair market  value,  determined as provided in Section
5(G) on the date of grant,  of the shares with respect to which  incentive stock
options are  exercisable  for the first time by an employee  during any calendar
year under all plans of the corporation  employing such employee,  any parent or
subsidiary  corporation of such  corporation and any predecessor  corporation of
any such corporation shall not exceed $100,000. If the date on which one or more
of such  incentive  stock options could first be exercised  would be accelerated
pursuant to any  provision  of the Plan or any stock option  agreement,  and the
acceleration of such exercise date would result in a violation of the limitation
set forth in the proceeding sentence, then,  notwithstanding any such provision,
but subject to the  provisions  of the next  succeeding  sentence,  the exercise
dates of such incentive  stock options shall be accelerated  only to the date or
dates, if any, that do not result in a violation  of such  limitation  and, in 


<PAGE>



such event,  the exercise  dates of the incentive  stock options with the lowest
option prices shall be  accelerated  to the earliest  such dates.  The Committee
may, in its discretion,  authorize the  acceleration of the exercise date of one
or more  incentive  stock  options even if such  acceleration  would violate the
$100,000  limitation  set forth in the first sentence of this paragraph and even
if such  incentive  stock  options are thereby  converted in whole or in part to
nonstatutory stock options.

    The Committee may accept the  cancellation  of outstanding  stock options in
return for the grant of new stock options for the same or a different  number of
shares and at the same or a different option price.

                                    SECTION 5
                      TERMS AND CONDITIONS OF STOCK OPTIONS

    Stock options granted under the Plan shall be subject to the following terms
and conditions:

     (A)  The purchase  price at which each stock  option may be exercised  (the
          "option  price")  shall  be  such  price  as  the  Committee,  in  its
          discretion,  shall  determine  but shall not be less than one  hundred
          percent  (100%) of the fair market value per share of the Common Stock
          covered by the stock  option on the date of grant,  except that in the
          case  of  an  incentive  stock  option  granted  to an  employee  who,
          immediately  prior to such grant,  owns stock possessing more than ten
          percent  (10%) of the total  combined  voting  power of all classes of
          stock of the Corporation or any Subsidiary (a "Ten Percent Employee"),
          the option price shall not be less than one hundred ten percent (110%)
          of such fair market  value on the date of grant.  For purposes of this
          Section  5(A),  the fair  market  value of the Common  Stock  shall be
          determined as provided in Section  5(G).  For purposes of this Section
          5(A), an individual  (i) shall be considered as owning not only shares
          of stock owned  individually  but also all shares of stock that are at
          the  time  owned,  directly  or  indirectly,  by or  for  the  spouse,
          ancestors,  lineal  descendants,  and brothers and sisters (whether by
          the  whole  or half  blood)  of such  individual  and  (ii)  shall  be
          considered as owning  proportionately  any shares  owned,  directly or
          indirectly, by or for any corporation, partnership, estate or trust in
          which such individual is a shareholder, partner or beneficiary.

     (B)  The  option  price for each  stock  option  shall be paid in full upon
          exercise  and  shall  be  payable  in cash in  United  States  dollars
          (including check,  bank draft or money order),  which may include cash
          forwarded  through  a broker  or  other  agent-sponsored  exercise  or
          financing program;  provided,  however,  that in lieu of such cash the
          person exercising the stock option may (if authorized by the Committee
          at the time of grant in the case of an incentive  stock option,  or at
          any time in the case of a  nonstatutory  stock  option) pay the option
          price in whole or in part by delivering to the  Corporation  shares of
          the Common  Stock  having fair market value on the date of exercise of
          the stock option, determined as provided in Section 5(G), equal to the
          option  price for the  shares  being  purchased;  except  that (i) any
          portion of the option price  representing  a fraction of a share shall
          in any event be paid in cash and (ii) no shares  of the  Common  Stock
          which have been held for less than six months may be delivered in


<PAGE>



          payment  of  the  option  price  of a  stock  option.  If  the  person
          exercising  a  stock  option   participates   in  a  broker  or  other
          agent-sponsored  exercise or financing  program,  the Corporation will
          cooperate with all reasonable  procedures of the broker or other agent
          to permit  participation by the person  exercising the stock option in
          the exercise or financing  program.  Notwithstanding  any procedure of
          the broker or other  agent-sponsored  program,  if the option price is
          paid in cash,  the exercise of the stock option shall not be deemed to
          occur and no  shares  of the  Common  Stock  will be issued  until the
          Corporation has received full payment in cash (including  check,  bank
          draft or money  order) for the  option  price from the broker or other
          agent.  The date of exercise  of a stock  option  shall be  determined
          under procedures  established by the Committee,  and as of the date of
          exercise the person  exercising  the stock option shall be  considered
          for all  purposes to be the owner of the shares with  respect to which
          the stock option has been exercised.  Payment of the option price with
          shares  shall not  increase  the number of shares of the Common  Stock
          which may be issued under the Plan as provided in Section 3.

     (C)  No stock option shall be exercisable by a grantee during the first six
          months of its term,  except that this limitation on exercise shall not
          apply if Section  7(B)  becomes  applicable.  No stock option shall be
          exercisable  after the expiration of ten years (five years in the case
          of incentive stock option granted to a Ten Percent  Employee) from the
          date of grant.  A stock option to the extent  exercisable  at any time
          may be exercised in whole or in part.

     (D)  No stock option shall be transferable by the grantee otherwise than by
          will,  or if the grantee  dies  intestate,  by the laws of descent and
          distribution  of the state of  domicile  of the grantee at the time of
          death.  All stock options shall be exercisable  during the lifetime of
          the grantee only by the grantee.

     (E)  Subject to the provisions of Section 4 in the case of incentive  stock
          options,  unless the Committee,  in its  discretion,  shall  otherwise
          determine:

           (i) If the  employment  of a grantee who is not  disabled  within the
               meaning of Section  422(c)(6) of the Code (a "Disabled  Grantee")
               is voluntarily or  involuntarily  terminated  with the consent of
               the  Corporation  or  Subsidiary  or a grantee  retires under any
               retirement  plan of the  Corporation  or a  Subsidiary,  any then
               outstanding  incentive stock option held by such grantee shall be
               exercisable by the grantee (but only to the extent exercisable by
               the grantee  immediately  prior to the termination of employment)
               at any time prior to the expiration  date of such incentive stock
               option or within three months  after the date of  termination  of
               employment, whichever is the shorter period;

          (ii) If the employment of a grantee who is not a Disabled Grantee


<PAGE>



               is voluntarily or  involuntarily  terminated  with consent of the
               Corporation or a Subsidiary,  any then  outstanding  nonstatutory
               stock option held by such  grantee  shall be  exercisable  by the
               grantee  (but  only  to the  extent  exercisable  by the  grantee
               immediately  prior to the  termination of employment) at any time
               prior to the expiration date of such nonstatutory stock option or
               within  one year  after the date of  termination  of  employment,
               whichever is the shorter period;

         (iii) If the  employment  of a grantee  who is a  Disabled  Grantee  is
               voluntarily or  involuntarily  terminated with the consent of the
               Corporation or a Subsidiary,  any then  outstanding  stock option
               held by such grantee shall be  exercisable by the grantee in full
               (whether or not so exercisable by the grantee  immediately  prior
               to the  termination  of  employment)  by the  grantee at any time
               prior to the  expiration  date of such stock option or within one
               year after the date of termination  of  employment,  whichever is
               the shorter period;

          (iv) If a grantee retires under any retirement plan of the Corporation
               or a Subsidiary,  any then outstanding  nonstatutory stock option
               held by such  grantee  shall be  exercisable  by the grantee (but
               only to the extent  exercisable by the grantee  immediately prior
               to such  retirement) at any time prior to the expiration  date of
               such  nonstatutory  stock  option or within three years after the
               date of retirement, whichever is the shorter period;

           (v) Following  the  death  of  a  grantee  during   employment,   any
               outstanding stock option held by the grantee at the time of death
               shall be  exercisable  in full (whether or not so  exercisable by
               the grantee immediately prior to the death of the grantee) by the
               person  entitled to do so under the will of the  grantee,  or, if
               the grantee shall fail to make  testamentary  disposition  of the
               stock option or shall die intestate,  by the legal representative
               of the grantee at any time prior to the  expiration  date of such
               stock  option  or  within  one  year  after  the  date of  death,
               whichever is the shorter period;

          (vi) Following the death of a grantee after  termination of employment
               during  a  period  when  a  stock  option  is  exercisable,   any
               outstanding stock option held by the grantee at the time of death
               shall be exercisable  by such person  entitled to do so under the
               will of the grantee by such legal representative (but only to the
               extent  the  stock   option  was   exercisable   by  the  grantee
               immediately  prior to the death of the grantee) at any time prior
               to the  expiration  date of such stock  option or within one year
               after the date of death, whichever is the shorter period; and

         (vii) If a grantee of a stock option (a) engages in the operation or


<PAGE>



               management  of a business  (whether as owner,  partner,  officer,
               director,  employee  or  otherwise  and  whether  during or after
               termination  of  employment)  which  is in  competition  with the
               Corporation or any of its Subsidiaries,  (provided, however, that
               this clause  shall not apply if Section  7(C)  applies  following
               termination of employment), (b) induces or attempts to induce any
               customer, supplier, licensee or other individual,  corporation or
               other business  organization having a business  relationship with
               the  Corporation  or any  of  its  Subsidiaries  to  cease  doing
               business with the  Corporation or any of its  Subsidiaries  or in
               any  way  interferes  with  the  relationship  between  any  such
               customer,  supplier, licensee or other person and the Corporation
               or any of its  Subsidiaries  or (c)  solicits any employee of the
               Corporation  or any of its  Subsidiaries  to leave the employment
               thereof or in any way interferes  with the  relationship  of such
               employee with the  Corporation  or any of its  Subsidiaries,  the
               Committee,  in its  discretion,  may  immediately  terminate  all
               outstanding stock options held by the grantee.  Whether a grantee
               has engaged in any of the activities referred to in the preceding
               sentence  which would cause the  outstanding  stock options to be
               terminated  shall  be  determined,  in  its  discretion,  by  the
               Committee,  and any such  determination by the Committee shall be
               final and binding.

     (F)  All stock options shall be confirmed by an agreement,  or an amendment
          thereto,  which shall be executed on behalf of the  Corporation by the
          President and Chief Executive Officer,  the Chief Financial Officer or
          any Vice  President  and by the grantee.  The  agreement  confirming a
          stock  option shall  specify  whether the stock option is an incentive
          stock option or a  nonstatutory  stock option.  The provisions of such
          agreements need not be identical.

     (G)  Fair market  value of the Common  Stock shall be the mean  between the
          following prices, as applicable,  for the date as of which fair market
          value is to be determined as quoted in The Wall Street  Journal (or in
          such other reliable  publication as the Committee,  in its discretion,
          may determine to rely upon):  (i) if the Common Stock is listed on the
          American or the New York Stock Exchange,  the highest and lowest sales
          prices  per  share of the  Common  Stock as  quoted  in the  Composite
          Transactions  listing  for such  exchange  on such  date,  (ii) if the
          Common  Stock is not listed on either such  exchange,  the highest and
          lowest sales prices per share of the Common Stock for such date on (or
          on  any  composite  index   including)  the  principal  United  States
          securities  exchange registered under the 1934 Act on which the Common
          Stock is  listed,  or (iii) if the  Common  Stock is not listed on any
          such  exchange,  the highest and lowest  sales prices per share of the
          Common Stock for such date on the National  Association  of Securities
          Dealers Automated Quotation System or any successor system then in use
          ("NASDAQ"). If there are no such sale price quotations for the date as
          of which fair market value is to be determined but there are such sale
          price quotations within a reasonable period both before and after such


<PAGE>



          date,  then fair market value shall be determined by taking a weighted
          average of the means  between the highest and lowest  sales prices per
          share of the Common  Stock as so quoted on the nearest date before and
          the nearest date after the date as of which fair market value is to be
          determined. The average should be weighted inversely by the respective
          numbers of trading days  between the selling  dates and the date as of
          which fair market value is to be determined. If there are no such sale
          price  quotations  on or within a  reasonable  period  both before and
          after the date as of which fair market value is to be determined, then
          fair market  value of the Common  Stock shall be the mean  between the
          bona fide bid and asked  prices per share of Common Stock as so quoted
          for such date on NASDAQ, or if none, the weighted average of the means
          between  such bona fide bid and asked  prices on the  nearest  trading
          date  before and the nearest  trading  date after the date as of which
          fair market value is to be determined, if both such dates are within a
          reasonable  period.  The  average  is to be  determined  in the manner
          described  above in this Section 5(G). If the fair market value of the
          Common Stock cannot be determined on the basis previously set forth in
          this  Section 5(G) for the date as of which fair market value is to be
          determined,  the  Committee  shall in good  faith  determine  the fair
          market value of the Common Stock on such date. Fair market value shall
          be  determined   without  regard  to  any  restriction  other  than  a
          restriction which, by its terms, will never lapse.

     (H)  The obligation of the  Corporation to issue shares of the Common Stock
          under  the  Plan  shall  be  subject  to (i)  the  effectiveness  of a
          registration  statement  under the Securities Act of 1933, as amended,
          with respect to such shares,  if deemed  necessary or  appropriate  by
          counsel for the Corporation,  (ii) the condition that the shares shall
          have been listed (or  authorized  for listing upon official  notice of
          issuance)  upon the American  Stock  Exchange or each such other stock
          exchange,  if any, on which the Common Stock shares may then be listed
          and (iii) all other  applicable  laws,  regulations,  rules and orders
          which may then be in effect.

     Subject  to the  foregoing  provisions  of this  Section  5 and  the  other
provisions of the Plan, any stock option granted under the Plan may be exercised
at such times and in such amounts and be subject to such  restrictions and other
terms and conditions,  if any, as shall be determined, in its discretion, by the
Committee  and set forth in the  agreement  referred to in Section  5(F),  or an
amendment thereto.

                                    SECTION 6
                      ADJUSTMENT AND SUBSTITUTION OF SHARES

     If a dividend or other distribution shall be declared upon the Common Stock
payable in shares of the Common Stock,  the number of shares of the Common Stock
subject to any outstanding  stock options and the number of shares of the Common
Stock  which may be issued  under the Plan but are not  subject  to  outstanding
stock options and the maximum  number of shares as to which stock options may be
granted  and as to which  shares may be awarded  under the Plan to any  employee
during any calendar year under Section 4 on the date fixed for  determining  the
shareholders  entitled to receive such stock dividend or  distribution  shall be
adjusted by adding  thereto the number of shares of the Common Stock which would
have been  distributable  thereon if such  shares had been  outstanding  on such
date.

     If the  outstanding  shares of the Common  Stock  shall be changed  into or
exchangeable  for a  different  number  or kind of  shares  of  stock  or  other
securities  of  the   Corporation  or  another   corporation,   whether  through
reorganization, reclassification,  recapitalization, stock split-up, combination
of shares,  merger or  consolidation,  then there shall be substituted  for each
share of the Common Stock subject to any then  outstanding  stock option and for
each share of the Common  Stock which may be issued  under the Plan but which is
not then subject to any outstanding stock option,  the number and kind of shares
of stock or other  securities  into which each  outstanding  share of the Common
Stock shall be so changed or for which each such share shall be exchangeable.

     In case of any adjustment or  substitution as provided for in the first two
paragraphs of this Section 6, the aggregate  option price for all shares subject
to each then  outstanding  stock option prior to such adjustment or substitution
shall be the aggregate  option price for all shares of stock or other securities
(including  any fraction) to which such shares shall have been adjusted or which
shall have been  substituted  for such  shares.  Any new option  price per share
shall be carried to at least three  decimal  places with the last decimal  place
rounded upwards to the nearest whole number.

     If the outstanding  shares of the Common Stock shall be changed in value by
reason  of  any  spin-off,   split-off  or  split-up,  or  dividend  in  partial
liquidation, dividend in property other than cash, or extraordinary distribution
to shareholders of the Common Stock, the Committee shall make any adjustments to
any then outstanding stock option which it determines are equitably  required to
prevent dilution or enlargement of the rights of optionees which would otherwise
result from any such transaction.

     No adjustment or substitution  provided for in this Section 6 shall require
the  Corporation  to issue  or sell a  fraction  of a share  or other  security.
Accordingly,  all fractional  shares or other  securities  which result from any
such adjustment or  substitution  shall be eliminated and not carried forward to
any subsequent adjustment or substitution.

     If any such  adjustment  or  substitution  provided  for in this  Section 6
requires the approval of shareholders in order to enable the Corporation to


<PAGE>



grant incentive stock options,  then no such adjustment or substitution shall be
made without the required shareholder  approval.  Notwithstanding the foregoing,
in the case of incentive stock options,  if the effect of any such adjustment or
substitution  would be to cause the stock  option to fail to continue to qualify
as an incentive stock option or to cause a modification, extension or renewal of
such stock option  within the meaning of Section 424 of the Code,  the Committee
may elect that such adjustment or substitution  not be made but rather shall use
reasonable  efforts to effect  such other  adjustment  of each then  outstanding
stock option as the Committee, in its discretion, shall deem equitable and which
will not  result in any  disqualification,  modification,  extension  or renewal
(within the meaning of Section 424 of the Code) of such incentive stock option.

     Except as  provided  in this  Section 6, a grantee  shall have no rights by
reason  of any  issue by the  Corporation  of stock of any  class or  securities
convertible  into stock of any class, any subdivision or consolidation of shares
of stock of any class,  the payment of any stock  dividend or any other increase
or decrease in the number of shares of stock of any class.


                                    SECTION 7
                       ADDITIONAL RIGHTS IN CERTAIN EVENTS

               following such  transaction a majority of the Voting Power of (i)
               in the  case of a  merger  or  consolidation,  the  surviving  or

in the Plan, all stock options held by a grantee (other than a grantee  referred
to in the proviso to Section 7(A)(6)) whose employment with the Corporation or a
Subsidiary  terminates  within  one year of any  Section 7 Event for any  reason
other  than  voluntary  termination  with the  consent of the  Corporation  or a
Subsidiary,  retirement  under  any  retirement  plan  of the  Corporation  or a
Subsidiary or death,  which are exercisable shall continue to be exercisable for

event after the expiration date of the stock option.


                                    SECTION 8
          EFFECT OF THE PLAN ON THE RIGHTS OF EMPLOYEES AND EMPLOYER

     Neither  the  adoption  of the  Plan  nor any  action  of the  Board or the

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS

As  discussed  more fully in Note 2 to the  consolidated  financial  statements,
during the fourth quarter of 1998, the Company  recorded  losses  totaling $10.9
million related to a construction project being performed by Baker Mellon Stuart
Construction, Inc. ("BMSCI") for Universal City Development Partners ("UCDP") at
the  Universal  Studios  theme park in  Orlando,  Florida.  Other  BMSCI-related
charges  totaling $2.8 million were also recorded  during the fourth  quarter of
1998.  Following these charges,  the Company determined during the first quarter
of 1999 that it will no longer  participate in low-bid,  high-risk  construction
projects  for  buildings  or  transportation  infrastructure.  Accordingly,  the
general  construction  activities  of the  Company's  Buildings  unit  have been
restructured,  and its Transportation  Construction (heavy and highway) business
will be sold.  In connection  with this  restructuring,  the Company  recorded a
charge of $0.8 million during the first quarter of 1999.

Total Contract Revenues

Total  contract  revenues  reached a record $521  million in 1998,  up from $446
million in 1997. All of the Company's business units posted revenue improvements
for 1998.  The  Buildings,  Transportation,  Energy and Civil units recorded the
largest  increases  of $25 million,  $22  million,  $14 million and $13 million,
respectively.  In the Buildings unit, the UCDP project accounted for $60 million
of  revenues  (or 11.5% of  revenues  for the  Company)  in 1998 versus only $17
million in 1997.  Nearly equal  revenue  growth in each of the  engineering  and
construction  divisions  contributed to the Transportation  unit's  improvement.
International growth, including that from a new consolidated joint venture which
provides  operations and maintenance  ("O&M") services to BP Amoco in Venezuela,
caused the increase in the Energy unit. The Civil unit's improvement principally
resulted  from  higher  revenues  on new  O&M  contracts  in its  Baker  Support
Services, Inc. ("BSSI") division.

For 1997,  total  contract  revenues  increased  from $418 million in 1996.  The
Transportation, Energy and Civil units recorded the largest revenue increases of
$14 million, $12 million and $9 million,  respectively.  Revenue growth from new
heavy and 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  again  resulted from higher  revenues on new O&M contracts in its BSSI
division,  despite lower  revenues in its  engineering  division due to the 1997
completion of its significant project in Mexico.

</TABLE>

Gross Profit 

Gross profit  decreased to $47.2 million in 1998 from $51.9 million
in 1997. As a percentage of total contract revenues, gross profit declined to 9%
in  1998  compared  to  12%  in  1997.  Both  overall   decreases  are  directly
attributable to the construction project charges totaling $13.7 million recorded
in the  Buildings  unit  during the fourth  quarter  of 1998.  The gross  profit
<PAGE>

percentage  increased  for all of the  Company's  business  units except for the
Civil unit,  which remained  relatively flat, and the Buildings unit. The Energy
and Transportation units registered the most significant overall improvements in
1998. The Energy unit's international growth,  particularly in Venezuela, raised
its gross profit percentage. Both the engineering and construction operations in
the  Transportation  unit contributed to its  improvement,  with the engineering
side providing the greater increase due to higher profitability from several new
projects on which work commenced during 1998. After excluding the aforementioned
1998  construction  losses,  the Buildings unit's gross profit  percentage still
would have been lower for 1998 as the result of its  completion  of certain more
profitable construction projects in late 1997 and early 1998.

For 1997,  gross profit increased from $48.6 million in 1996. As a percentage of
total contact revenues, gross profit remained relatively constant at 12% in both
1997 and 1996.  The gross  profit  percentage  increased  in 1997 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.

Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses increased to $48.9 million
in 1998 from $43.9 million in 1997. The 1998 increase  principally  reflected an
investment  in  technological  support  costs,  entry  into  new  transportation
markets,  additional  support costs  related to the Energy  unit's  consolidated
joint venture in Venezuela,  and higher international marketing costs. Expressed
as a percentage of total contract revenues,  SG&A expenses decreased slightly to
9.4% in 1998 from 9.8% in 1997.

SG&A expenses  increased 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, SG&A expenses remained constant at 9.8% in both 1997 and 1996.

Other Income and Expense

Interest income  decreased to $439,000 in 1998 from $552,000 in 1997, due to the
combination  of a lower  daily  average  investment  amount and  slightly  lower
interest rates in 1998.  Other income decreased to $42,000 in 1998 from $811,000
in 1997,  primarily due to 1998 expense related to the minority  interest in the
income of a  consolidated  Energy unit joint venture and 1997 gains  realized on
the sales of certain investments. Interest expense increased to $145,000 in 1998
from  $39,000 in 1997 as the result of financing  the purchase of certain  heavy
and highway construction equipment during the second half of 1998.

Interest income  increased 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 in 1997 from $50,000 in 1996,  primarily due to
gains  realized  on the sales of certain  investments  and equity  income from a
another Energy unit joint venture related to work in the Gulf of Mexico.

Income Taxes 

The  provision  for income taxes  resulted in an effective  tax rate of (82)% in
1998, 47% in 1997, and 48% in 1996. The difference between these percentages and
the 34% statutory U.S. federal rate is attributable primarily to state and
<PAGE>
foreign income taxes and foreign  withholding  taxes. The income tax expense for
1998 results from certain  foreign and state taxes that cannot be offset against
tax  benefits   derived  from  other   jurisdictions,   despite  the   Company's
consolidated  pre-tax loss. The 1996 provision rate was unfavorably  impacted by
higher foreign income taxes paid in that year.

CONTRACT BACKLOG

The Company's funded backlog, which consists of that portion of uncompleted work
represented  by  signed  contracts  and  for  which  the  procuring  agency  has
appropriated  and allocated  the funds to pay for the work,  was $448 million at
December 31, 1998, an increase from $393 million at the end of 1997. The overall
increase in funded backlog is  attributable to new work added and transfers from
unfunded backlog during the year.

Total backlog,  which incrementally  includes that portion of contract value for
which options are still to be exercised (unfunded backlog),  was $735 million at
the end of 1998 versus $649  million at the end of 1997.  With the  exception of
the Civil and Buildings units, each of the Company's business units entered 1999
with higher funded and total backlog than at the end of 1997.

With reference to the Company's  restructuring  announced in April 1999,  funded
backlog related to the businesses that will be continued by the Company was $300
million and $252  million,  and total backlog was $587 million and $508 million,
as of year-end 1998 and 1997, respectively.

LIQUIDITY AND CAPITAL RESOURCES

Net cash used in operating activities was $1.4 million in 1998, compared to cash
provided by  operating  activities  of $7.8  million in 1997 and $1.2 million in
1996.  The decrease for 1998 was  primarily  related to the  Company's  1998 net
loss.  The 1997  improvement  was  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 in the Buildings unit.

Net cash used in investing  activities  was $11.4  million in 1998,  compared to
$2.5 million in 1997 and $3.7 million in 1996.  These  amounts  solely  comprise
capital  expenditures  in 1996 and 1997,  but the 1998 amount also includes $0.8
million paid during the fourth  quarter of 1998 relative to the  acquisition  of
GeoResearch, Inc.  The 1998 capital expenditures  totaling $10.6 million include
computer equipment and software purchases totaling $3.9 million as compared with
$1.4 million in 1997.  During 1997 and 1996,  the Company  acquired  most of its
computer  equipment  under  operating  leases,  but converted to the purchase of
computer  equipment for economic  reasons in 1998. An additional $3.5 million of
the 1998  expenditures  is  attributable  to the  purchase  of heavy and highway
construction  equipment needed for new projects added during 1998. These factors
account for the majority of the 1998 increase in capital expenditures.  The 1997
decrease is attributable to higher 1996  expenditures for building  improvements
and office equipment related to the Buildings unit's 1996 relocation from
<PAGE>
Pittsburgh to Coraopolis,  PA, and higher vehicle and equipment purchases during
1996 to meet the requirements of new BSSI O&M projects in the Civil unit.

Net cash  provided by  financing  activities  was $1.9  million in 1998 and $0.1
million in 1997,  compared to cash used in financing  activities of $1.3 million
in  1996.  The  1998  proceeds  from  long-term  debt  related  entirely  to the
aforementioned purchase of heavy and highway construction  equipment,  while the
repayments  of  long-term  debt  correlate  to both  the  financed  construction
equipment  and the 1998  subsidiary  acquisition.  In late 1996,  pursuant to an
announced  stock  repurchase  program,  the Company paid $1.3 million to acquire
207,560  treasury  shares.  In  1998,  the  Company  paid  $0.8  million  for an
additional 96,379 treasury shares under this program.

Working  capital  decreased  to $31.9  million at  December  31, 1998 from $36.2
million at December  31,  1997.  The  Company's  current  ratios were 1.36:1 and
1.41:1 at the end of 1998 and 1997,  respectively.  Both the working capital and
current ratio at year-end 1998 were negatively  impacted by the Buildings unit's
construction-related charges recorded during the fourth quarter of 1998.

In July 1998, the Company  extended the term of its unsecured  credit  agreement
with Mellon Bank,  N.A.  through May 31,  2001.  This  agreement  provides for a
commitment of $25 million,  which covers borrowings and letters of credit. As of
December 31, 1998, no borrowings were  outstanding;  however,  letters of credit
totaling $1.8 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,  and has a $500 million bonding line available  through
Travelers  Casualty & Surety Company of America.  Based on the Company's plan of
restructuring announced in April 1999, management believes that its bonding line
will be sufficient to meet its bid and  performance  needs for at least the next
year.

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  could  affect  the  Company.  The new  federal  transportation
legislation  (TEA-21)  will  provide  a  significant  increase  in  funding  for
transportation  infrastructure  projects  in 1999  and  beyond.  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.

YEAR 2000 COMPLIANCE

The Company has completed an assessment of its information  systems  relative to
the arrival of the 21st century.  For internal  systems,  the Company  generally
utilizes  modern  technologies  supplied and  supported by leading  hardware and
software providers suited to Baker's areas of business.  Year 2000 compliance is
primarily  being  achieved  through the normal and  recurring  process of system
upgrades,  the software  costs of which are covered  under  related  maintenance
agreements.
<PAGE>

Vendors have asserted that the financial and project  management systems for the
Company's engineering and construction businesses,  its BSSI subsidiary, and one
of two such systems in the Energy unit are Year 2000 compliant. The other Energy
unit system is currently being assessed and scheduled to be compliant by the end
of the  third  quarter  of 1999.  Over 90% of the  Company  is served by a human
resources  system  which  the  vendor  has  stated  to be Year  2000  compliant.
Validation  testing of the Company's  financial,  project  management  and human
resources  systems  is  expected  to be  completed  during  the second and third
quarters of 1999.

The Company's  interrelated systems (e.g., e-mail, file sharing) are linked by a
network of servers.  Upgrades  to  compliant  versions  are already in place for
approximately  95% of the network.  The  remaining  servers are  scheduled to be
upgraded to compliant  versions or merged with existing compliant servers during
the second  quarter of 1999.  The Company is in the process of evaluating  other
less  critical  operational  support  systems  being used in all business  units
(e.g., mapping, CADD, cost estimating, databases,  spreadsheets, and specialized
and customized  software) to identify any remaining  issues for resolution.  Any
related issues are scheduled for resolution during the second and third quarters
of 1999. Normal end-user computing needs were addressed with BIOS testing of all
personal  computers and a review of the operating systems and software packages.
Patches and upgrade  needs have been  identified  and are being  applied  with a
scheduled completion date during the third quarter of 1999.

The Company is a service-based organization and, as such, has little reliance on
embedded technology (e.g., microcontrollers) for its key business processes. The
relevance of embedded  technology is limited to such items as  elevators,  HVAC,
security,  etc.,  which  are  components  of the  Company's  leased  facilities.
Embedded technology is also integral to some client facilities which the Company
operates and maintains  under customer  contracts.  Responsibility  for the Year
2000 compliance of such facilities rests with the customers.

To assess the Year 2000 compliance of significant third parties, the Company has
initiated a survey process to gather and evaluate  information  from significant
business  customers,  vendors  and  subcontractors.  Mailing  of the  survey was
completed  during the first  quarter of 1999.  The  majority  of  responses  are
expected to be received  by the end of the second  quarter of 1999.  The Company
will continue to evaluate the readiness of its key suppliers and customers  with
follow-up  requests  to  non-respondents   and  respondents  that  are  not  yet
compliant; such requests will continue through the end of 1999.

Management  currently  believes that its "most reasonably likely worst case Year
2000  scenario"  poses the  potential  for payment  delays from some  customers,
including  agencies  of the  U.S.  federal  government,  due to  their  lack  of
readiness for the new century.  A formal  assessment of the potential  impact of
this scenario has not yet been evaluated and is dependent upon the completion of
the aforementioned customer survey process.

Based on the customer survey results, the Company will also enhance its existing
disaster  recovery plans to include  assessments of potential Year 2000 impacts.
These  contingency  plans will address both internal  factors  related to staff,
computer  systems  and  facilities,  as  well as  external  factors  related  to
suppliers,  customers  and service  providers.  The Company  expects to have all
necessary contingency plans in place by the end of 1999.

Based upon information currently available, management does not believe that the
estimated  incremental  costs  associated  with  Year  2000  compliance  will be
material  to the  Company's  consolidated  results of  operations  or  financial
position.

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,  and joint  ventures  over which it  maintains  control.  All
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 majority of 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  principally  recorded as costs are  incurred.  In the event that
legal  costs are  expected  to be  incurred in  connection  with  defending  the
Company's  position related to claims or litigation on projects,  such costs are
accrued  at the  time  they  are  probable  of  being  incurred  and  reasonably
estimable.  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  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,  project-specific  joint  ventures  based on the  equity
method of  accounting  for  investments.  The Company's  proportionate  share of
majority-owned,  project-specific 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.

Cash and Cash  Equivalents 
Cash and cash  equivalents  include  cash on hand or  deposit  and other  highly
liquid  instruments  with original  maturities of three months or less.  Any net
outstanding  checks within banking  institutions  are  reclassified  as accounts
payable; such amount totaled $9,141,000 at December 31, 1998.
<PAGE>
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  3 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 5 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
10 to 30 years.

Earnings Per Common Share
Basic and diluted  net income per share  computations  are based upon  8,178,067
weighted  average  shares  outstanding  for  1998.  Basic net  income  per share
computations are based upon weighted  averages of 8,207,786 and 8,372,034 shares
outstanding  for the years 1997 and 1996,  respectively.  Diluted net income per
share  computations are based upon weighted  averages of 8,299,083 and 8,382,592
shares outstanding for the years 1997 and 1996, respectively.

Reclassifications
Certain 1997 and 1996  financial  statement  amounts have been  reclassified  to
conform with 1998 classifications.

2. CONSTRUCTION CHARGES AND RESTRUCTURING

During the fourth  quarter of 1998, the Company  recorded  losses related to the
CityWalk   construction   project   being   performed  by  Baker  Mellon  Stuart
Construction,  Inc.  ("BMSCI"),  a wholly-owned  subsidiary of the Company,  for
Universal City Development Partners ("UCDP") at the Universal Studios theme park
in Orlando, Florida. This project involved the construction of a new entrance to
the park, which comprises a shopping area, restaurants and a large cineplex, and
represented BMSCI's largest active construction contract during 1998. Under this
contract,  BMSCI acted as the construction  manager and self-performed a portion
of the work.

Following its inception in May 1997,  the project  suffered  delays  because its
design and related  drawings  were  changed  substantially  during the course of
construction.  On March 5, 1999, BMSCI was terminated by UCDP from this project,
which was over 90%  completed.  UCDP alleges  contract  breaches  related to the
quality of work,  contract  administration  and delays in project completion and
seeks damages,  including  consequential damages related to project delays. Both
parties filed  lawsuits in this matter  during the first quarter of 1999.  BMSCI
alleges  unfair and deceptive  trade  practices,  breach of implied  warranty of
plans and specifications,  breach of contract,  wrongful  termination,  tortious
interference with business relationships, and breach of implied contract of good
faith and fair dealing,  and seeks damages,  interest,  court costs, and further
relief.  Certain  subcontractors  have also sued BMSCI and its  surety,  seeking
reimbursement  for costs  incurred and related  damages.  Additional  claims and
litigation may be filed in connection with this matter.

The losses recorded by the Company related to this project in the fourth quarter
of 1998 totaled $10.9  million,  and reflect costs incurred in excess of amounts
provided  for in the  contract,  estimated  legal costs to defend the  Company's
position,  the reversal of the  cumulative  gross profit  totaling  $1.1 million
recorded  through the third quarter of 1998,  and certain other costs related to
the termination.  Through  December 31, 1998, the Company has recorded  adjusted
revenues  totaling $76.9 million ($60.2 million during 1998),  and had been paid
$67.0 million, in connection with this contract.
<PAGE>
As of March 5, 1999, the Company is aware of  subcontractors'  allegations,  for
amounts in excess of $12 million,  representing  work  performed  for which they
have not been paid. Management and its counsel believe that under the provisions
of BMSCI's agreements with it subcontractors, it is not probable that BMSCI will
be  required to make  payments  for such work to the  subcontractors  unless and
until BMSCI is paid by UCDP. The Company is also aware of material  asserted and
unasserted claims by the  subcontractors.  In addition to the defenses described
below, the Company's  experience  indicates that  subcontractor  claims of these
types  are often  proven to be  significantly  in excess of  amounts  ultimately
recoverable.

BMSCI and its counsel  believe it has valid  claims  against  UCDP and  defenses
against claims by both UCDP and the subcontractors,  and BMSCI intends to defend
its  position  vigorously.  No amounts  have been  accrued at December 31, 1998,
associated  with the ultimate  resolution  of this matter in excess of the items
discussed  above,  since  management and its counsel believe any such additional
costs are neither probable of payment nor reasonably estimable at this time.

The Company expects this matter to be resolved  through a trial over a number of
years. It is reasonably  possible that BMSCI may recover all or a portion of the
amounts  expensed  to date  on  this  project.  However,  it is also  reasonably
possible that there may be an  unfavorable  resolution  with respect to the UCDP
litigation  or  the   subcontractor   allegations  and  claims;  an  unfavorable
resolution with respect to either matter, or both, could have a material adverse
effect on the Company's consolidated  financial position,  results of operations
and cash flows in a future period.

Other charges totaling $2.8 million were also recorded during the fourth quarter
of 1998 related to the settlement of construction-related litigation and charges
on other completed construction projects.

In connection  with the foregoing,  the Company has  determined  that it will no
longer participate in low-bid,  high-risk construction projects for buildings or
transportation infrastructure.  Accordingly, the general construction activities
of the  Company's  Buildings  unit have  been  restructured,  and the  Company's
Transportation  Construction (heavy and highway) business will be sold. Existing
low-bid, high-risk construction projects in the Buildings unit will be completed
or sold.  Management  initiated  activities related to the sale of the heavy and
highway  business  during the second  quarter of 1999. In  connection  with this
restructuring,  the Company  recorded a charge of $0.8 million  during the first
quarter of 1999.

3. CONTRACTS

The  total  cost of  contracts  in  progress  (used  to  determine  cost of work
performed)  plus  accumulated  gross  profit  recorded  was  $1,007,668,000  and
$858,705,000  at December 31, 1998 and 1997,  respectively.  Billings to date on
contracts  in  progress  at December  31,  1998 and 1997 were  $994,829,000  and
$850,231,000, respectively.

Trade accounts  receivable  totaling  $9,097,000 and $12,088,000 at December 31,
1998 and 1997,  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, 1998 is expected to be collected in 1999.

As of  December  31, 1998 and 1997,  accounts  payable  included  amounts due to
subcontractors  of  $4,623,000  and  $8,888,000,  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
<PAGE>
participates  and the size,  scope and  duration of the  projects  vary  between
periods.  The Company's equity investment in these joint ventures was $2,028,000
and $1,737,000 at December 31, 1998 and 1997, 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.

4. BUSINESS SEGMENT INFORMATION

In 1998, the Company  adopted  Statement of Financial  Accounting  Standards No.
("SFAS")  131,   "Disclosures  about  Segments  of  an  Enterprise  and  Related
Information." SFAS 131 supersedes SFAS 14, "Financial  Reporting for Segments of
a Business  Enterprise,"  replacing  the  "industry  segment"  approach with the
"management"   approach.   The  management   approach  designates  the  internal
organization  that is used by  management  for making  operating  decisions  and
assessing  performance as the source of the Company's reportable segments.  SFAS
131 also requires disclosures about products and services, geographic areas, and
major  customers.  The adoption of SFAS 131 did not affect results of operations
or financial  position but did affect the disclosure of the segment  information
which follows.

The  Company  has five  operating  business  units.  The  Buildings,  Energy and
Environmental  units each  represent  reportable  segments  under SFAS 131.  The
Transportation   and  Civil  units  each  comprise  two   reportable   segments.
Accordingly, the Company has the following seven reportable segments:

o    The  Buildings  unit  has  historically  provided  a  variety  of  services
     including  design-build,   construction   management,   planning,   program
     management,   general  contracting,   architectural  and  interior  design,
     construction inspection and constructability reviews.

o    The Civil unit  includes two  reportable  segments.  The  Civil-Engineering
     segment  provides  surveying,   mapping,  geographic  information  systems,
     planning, design, construction management and total program management. The
     Civil-Baker Support Services,  Inc. ("BSSI") segment  principally  provides
     operations and maintenance services on U.S. military bases.

o    The Energy unit provides training,  personnel  recruitment,  pre-operations
     engineering,   field  operations  and  maintenance,   mechanical  equipment
     maintenance  and  logistics   management   services  for  operating  energy
     production facilities.

o    The Environmental  unit provides  environmental,  health and safety related
     engineering and consulting services in both the public and private markets.

o    The   Transportation   unit   includes   two   reportable   segments.   The
     Transportation-Engineering  segment provides planning, design, construction
     management and inspection  and management  consulting  services to highway,
     toll road and transit  agencies.  The  Transportation-Construction  segment
     acts as a general  contractor for highways,  bridges,  track  installation,
     sewer, water and other civil construction projects.
<PAGE>

The accounting  policies of the segments are the same as those  described in the
summary  of  significant   accounting   policies.   The  Company  evaluates  the
performance of its segments based on income before income taxes.

The following tables reflect disclosures  required by SFAS 131 for the Company's
seven segments (in millions):

Effective October 1, 1998, the Company acquired all of the outstanding shares of
capital  stock of  GeoResearch,  Inc.  from  its  shareholder  in a  transaction
accounted for as a purchase.  While this transaction is not considered  material
for purposes of detailed  disclosure,  the Company recorded  related  intangible
assets totaling $1,943,000 during the fourth quarter of 1998.

7. LONG-TERM DEBT AND BORROWING AGREEMENTS

The Company has 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, 2001. 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, 1998,  no  borrowings  were  outstanding;
however,  letters  of credit  totaling  $1,792,000  were  outstanding  under the
Agreement.


<PAGE>

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 maximum amount of borrowings outstanding under the Agreement during 1998 was
$6,974,000. For 1998, the average daily balance outstanding when the Company was
in a net borrowing  position was $2,584,000 at a weighted  average interest rate
of 8.0%. The proceeds of all loans under the Agreement were used to meet various
working  capital  requirements.  The Company did not borrow under the  Agreement
during 1997.

Other  amounts  totaling  $3,961,000  included  in other  accrued  expenses  and
long-term debt in the accompanying  Consolidated Balance Sheet represent amounts
due for  construction  equipment  financed in 1998 as well as amounts due to the
former owner of GeoResearch, Inc. These notes and obligations mature as follows:
$823,000 in 1999, $627,000 in 2000, $954,000 in 2001, $915,000 in 2002, $370,000
in 2003, and $272,000 thereafter. The interest rates with respect to these notes
ranged from 4.44% to 7.75% as of December 31, 1998.

8. CAPITAL STOCK

In 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  1998,  the
Company  repurchased  96,379  treasury  shares of Common Stock at market  prices
ranging  from $7.53 to $8.87 per share,  for a total price of  $800,000.  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 made no treasury share repurchases during 1997.

The Company's Common Stock is divided into two series, Common Stock and Series B
Common Stock. Each share of Common Stock entitles the holder thereof to one vote
on all matters submitted to the shareholders,  and each share of Series B Common
Stock entitles the holder thereof to ten votes on all such matters.

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, 1998 and
1997, there were no shares of such Preferred Stock outstanding.

9. LEASE COMMITMENTS

Rent expense under  noncancellable  operating  leases was  $11,687,000  in 1998,
$10,364,000 in 1997 and $9,972,000 in 1996.

Minimum annual rentals payable under noncancellable  operating leases in each of
the five years after December 31, 1998 are $11,220,000,  $9,250,000, $6,529,000,
$3,241,000 and $894,000,  respectively.  These  noncancellable  leases relate to
office space, computer equipment, office equipment,  construction equipment, and
vehicles, with lease terms ranging from one to 10 years.

</TABLE>

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, 1998.

11. 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 a certain deductible limit 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 by 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, except as discussed in
Note 2, 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.
<PAGE>

The Company  currently has two significant legal  proceedings  outstanding.  The
more significant of the two relates to BMSCI's  construction  contract with UCDP
(see related discussion in Note 2).

The other  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 accordance  with the purchase  agreement  related to its 1998  acquisition of
GeoResearch, Inc., the Company agreed to pay the former owner, who has continued
as an employee of the Company,  contingent consideration based on a formula tied
to the operating profit of the combined  geospatial  businesses,  in excess of a
specified  threshold,  for the year ending  December  31,  2001.  The  threshold
contemplates  substantial growth in the combined  businesses over the years 1999
through 2001. This contingent  consideration payment cannot exceed $5.3 million.
Any such  payment  would serve to increase  the  goodwill  associated  with this
acquisition.  It is currently  uncertain  whether any  contingent  consideration
payment will be required under the purchase agreement with GeoResearch, Inc.

At December 31, 1998,  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.

12. 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  effective January 1, 1999, the Company began matching 100%
of the  first  5-1/2%  of  eligible  salary  contributed  by  participants.  The
Company's matching contributions are invested not less than 25% in Michael Baker
Corporation  Common Stock,  with the remaining 75% being  available to invest in
Baker Common Stock or mutual funds, as directed by the  participants.  From July
1, 1997 through December 31, 1998, the Company's matching contributions were not
permitted to be less than 50% invested in Baker 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  $4,312,000,  $3,321,000 and $3,306,000 in 1998,
1997 and 1996, respectively.
<PAGE>

As of  December  31,  1998,  the  market  value  of  all  ESOP  investments  was
$91,037,000,  of which 40% represented the market value of the ESOP's investment
in Michael Baker  Corporation  Common Stock.  The Company's ESOP held 44% of the
shares and 73% of the voting power for the outstanding Common Stock and Series B
Common Stock of the Company at the end of 1998.

13. STOCK OPTION PLANS

As of December 31, 1998, the Company has two fixed stock option plans. Under the
amended 1995 Stock  Incentive  Plan (the "Plan"),  the Company may grant options
for an aggregate of 1,500,000 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. Options are
typically  granted  pursuant  to an  agreement  with the  employee,  under which
one-fourth of the options granted become  immediately  vested, and the remaining
three-fourths  vest in annual one-fourth  increments under the Plan. The options
under the Directors' Plan are fully vested at the date of grant.  Vested options
remain  exercisable  for a period of ten years  from the grant  date  under both
plans.  Under the Plan, the Company granted  special options during 1998,  which
vest in the year 2006, but whose vesting may be accelerated to the first quarter
of the year 2001 if the Company  meets its  pre-established  earnings  per share
goal for the year 2000.

Under the Directors  Plan, each  nonemployee  director was issued 500 restricted
shares of Common Stock for a total of 3,500 and 4,500 shares of restricted stock
issued in 1998 and 1997,  respectively.  Restrictions  on the shares  expire two
years after the issue date.

The following table summarizes all stock option activity for both plans in 1998,
1997 and 1996:

During  1996,  the  Company  adopted  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 1998,
1997 or 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/(loss)  amounts would have been $(2,669,000),
$4,725,000 and $4,077,000 for the years ended December 31, 1998,  1997 and 1996,
respectively.  The Company's pro forma diluted net income/(loss) per share would
have been $(0.33),  $0.57 and $0.49 for the years ended December 31, 1998, 1997,
and 1996, 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 5.9%,  weighted
average expected  volatility of 49.4%, 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  (the Company) at December 31, 1998 and
1997,  and the results of their  operations and their cash flows for each of the
three years in the period ended December 31, 1998, 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.

As discussed in Note 2 and Note 11 to the consolidated financial statements, the
Company  is  involved  in certain  contingencies,  the  outcome of which  cannot
presently be  determined.  Accordingly,  no provision for any liability that may
result from these  contingencies has been made in the accompanying  consolidated
financial statements.
