PART III -- NARRATIVE State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period. Michael Baker Corporation (the "Company") is filing this Form 12b-25 because additional time is needed for the Company to complete its Quarterly Report on Form 10-Q for the quarter ended September 30, 2005, which was due on November 9, 2005. The reason for the delay relates to the Company's continued inability to file its Quarterly Report on Form 10-Q for the quarter ended June 30, 2005. As described in its Form 12b-25 filed on August 10, 2005, the delay with respect to the Company's Form 10-Q for the quarter ended June 30, 2005 relates to (1) accrual issues in accounting for income tax expense and income tax withholding certificates in the Company's Nigerian operations and (2) the Company's assessment of the need to accrue an initial "incurred but not reported" liability for certain self-insured professional liability losses. Consequently, the Company has not been able to complete its financial statements for the three and nine months ended September 30, 2005, and the Company was not able to file its Form 10-Q for the quarterly period ended September 30, 2005 by the November 9, 2005 due date.

If answer is no, identify report(s). Yes [ ] No [X] Form 10-Q for the quarter ended June 30, 2005 (3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? Yes [X] No [ ] If so: attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made. The Company anticipates, but is not certain, that there will be a significant change in the results of operations for the corresponding period of the last fiscal year. Until the Company fully assesses the proper amount, classification and timing of the restatement adjustments for the matters discussed in Item III above, the Company will not be in a position to determine the significance of the change to the results of operations for the corresponding period of the last fiscal year. -------------------------------------------------------------------------------- Michael Baker Corporation -------------------------------------------------------------------- (Name of Registrant as Specified in Charter) has caused this notification to be signed on its behalf by the undersigned hereunto duly authorized.
