                    BANKRUPTCY COURT ISSUES ORDERS APPROVING
                  U.S. AGGREGATES DIP FACILITY ON A FINAL BASIS
                          AND SALE BIDDING PROCEDURES;
                    HART-SCOTT-RODINO WAITING PERIOD EXPIRES

DRAPER, UT, APRIL 12, 2002 - U.S. Aggregates, Inc., (OTC Bulletin Board: AGAT)
today announced that on April 1, 2002, Judge Gregg W. Zive of the U.S.
Bankruptcy Court in Reno, Nevada issued an order approving on a final basis a
$17.5 million debtor-in-possession (DIP) financing facility between U.S.
Aggregates and certain of its pre-petition lenders. The DIP financing facility,
which consists of $10 million in revolving loans and $7.5 million in letters of
credit, will enable the company to operate its business in the ordinary course
for one year, or until the sale of its assets is consummated, whichever comes
first.

U.S. Aggregates also announced that on April 9, 2002, Judge Zive issued an order
approving bidding and other sale procedures for the proposed sale of the
company's assets pursuant to Section 363 of the U.S. Bankruptcy Code. A key
element of this process will be a competitive bidding auction at which all
qualified parties can, and are encouraged to, bid for the assets of the entire
company or those of its Western or Southeastern business.

In addition, U.S. Aggregates announced that on April 2, 2002, the waiting period
under the Hart-Scott-Rodino Act of 1976 expired without inquiry by the Federal
Trade Commission or the Department of Justice. The waiting period pertained to
the notices filed in accordance with United States anti-trust laws by U.S.
Aggregates and Oldcastle Materials Inc. regarding the pending sale of U.S.
Aggregates' assets. Expiration or termination of the waiting period was a
condition to the sale of the company's assets to Oldcastle Materials, which sale
remains dependent on the results of the competitive bidding auction described
above.

As was announced in a press release dated March 11, 2002, U.S. Aggregates has
entered into an agreement for the sale of all its and its subsidiaries' assets
to Oldcastle Materials, Inc. for approximately $140,750,000. The agreement is
subject to bankruptcy court approval and the bidding process described above.
Proceeds received from the sale of U.S. Aggregates' assets will be applied to
the payment of certain liabilities not assumed by the buyer, including any funds
drawn from the DIP financing facility, and the payment of the company's
pre-petition senior secured debt. Currently, U.S. Aggregates' pre-petition
senior secured debt exceeds the total estimated proceeds to be received from the
sale of its remaining assets. The senior secured debt prior to establishment of
the DIP financing facility amounted to approximately $155,000,000. Unsecured
debt claims are estimated to be in excess of $75,000,000.

Founded in 1994, U.S. Aggregates, Inc. ("USAI") is a producer of aggregates.

used primarily for construction and maintenance of highways and other
infrastructure projects as well as for commercial and residential construction.
