("URS") to exchange an aggregate principal amount of up to $200,000,000 of its

12 1/4% Senior Subordinated Notes due 2009 (the "Old Notes"), which were
issued in an offering under Rule 144A of the Securities Act that were not
registered under the Securities Act. The Exchange Offer is being extended to
all holders of the Old Notes in order to satisfy certain obligations of URS
contained in the Registration Rights Agreement, dated as of June 23, 1999,
(the "Registration Rights Agreement"), among URS, URS's subsidiary guarantors,
and Morgan Stanley & Co. Incorporated. The New Notes are substantially
identical to the Old Notes, except that the transfer restrictions and
registration rights relating to the Old Notes do not apply to the New Notes.

New York City time, on September 16, 1999, unless the Exchange Offer is
extended. Any Old Notes tendered pursuant to the Exchange Offer may be
