agreement with a company providing engineering services to public

company is a diversified full service consulting engineering firm specializing
in government services with expertise in environmental, civil, mechanical,

history and reputation will provide a solid base of operations in the midwest.
The acquisition will add over 100 employees to The Keith Companies bringing its
total employee count to approximately 850 employees. The closing, pending final
due diligence, is scheduled for the end of February 2002. Complete details about
the acquisition will be provided in a company press release at the time of
closing.

        As a result of this planned acquisition, The Keith Companies is
increasing its annual 2002 guidance to reflect 10 months of operating results
from the acquired company. Estimated net revenue is projected to increase by
$10.0 million to $11.5 million, increasing the total estimated net revenue range
for 2002 to $92.0 million to $99.5 million. Diluted earnings per share is
anticipated to increase by $0.05 to $0.08 bringing the total estimated 2002
diluted earnings per share range to $0.85 to $1.00 ($0.17 to $0.20 for 1st
quarter, $0.21 to $0.25 for 2nd quarter, $0.25 to $0.29 for 3rd quarter, and
$0.22 to $0.26 for 4th quarter). Upon completion of the closing, The Company's
cash and securities balance should exceed $15 million.





        The Keith Companies Chairman and CEO, Aram H. Keith noted, "Our
strategic plan for diversification is right on track. This particular
acquisition will enhance our government services work significantly. It also
provides the opportunity to promote other Keith Companies services in the
midwest. Upon completing the transaction later this month, we will have closed
two energy related acquisitions and one in the public works/infrastructure
industry segment since completion of the Company's secondary stock offering in
May 2001."

        Further discussion about the planned acquisition will be provided by
