ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

         On February 27, 2004, the Michael Baker Corporation Employee Stock
Ownership Plan (the "Michael Baker ESOP") changed its auditors for year-end
2003. The Michael Baker ESOP Committee approved the dismissal of
PricewaterhouseCoopers LLP ("PricewaterhouseCoopers") as the independent public
accountants for the Michael Baker ESOP and appointed Schneider Downs & Co., Inc.
as the independent public accountants for the Michael Baker ESOP for the fiscal
year ended December 31, 2003.

         PricewaterhouseCoopers' audit reports on the Michael Baker ESOP's
financial statements for each of the past two fiscal years ended December 31,
2002 and December 31, 2001 did not contain any adverse opinions or disclaimers
of opinion, nor were such reports qualified or modified as to uncertainty, audit
scope or accounting principles.

         During the two most recent fiscal years ended December 31, 2002 and
December 31, 2001, and through February 27, 2004, there were no disagreements
with PricewaterhouseCoopers on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure which, if not
resolved to PricewaterhouseCoopers' satisfaction would have caused them to make
reference to the subject matter of the disagreement in connection with the audit
reports of the Michael Baker ESOP's financial statements for such years. During
the two most recent fiscal years ended December 31, 2002 and December 31, 2001,
and through February 27, 2004, there were no reportable events as described
under Item 304(a) (i) (v) of Regulation S-K.

         We provided PricewaterhouseCoopers with a copy of the foregoing
disclosures and requested from them a letter indicating whether they agree with
these disclosures. A copy of their letter dated March 4, 2004 is attached as
Exhibit 16.

         During the two most recent fiscal years ended December 31, 2002 and
December 31, 2001, and through the date hereof, the Michael Baker ESOP did not
consult Schneider Downs & Co., Inc. with respect to the application of
accounting principles to a specified transaction, either completed or proposed,
or the type of audit opinion that might be rendered on our financial statements,
or any other matters or reportable events as set forth in Items 304 (a) (2) (i)
and (ii) of Regulation S-K.
