"Company"), various financial institutions (the "Lenders") and
BANK OF AMERICA, N.A., as agent for the Lenders (the "Agent").
Unless otherwise defined herein, terms defined in the Credit
Agreement are used herein as defined in the Credit Agreement.

     WHEREAS, the parties hereto desire to amend the Credit
Agreement in certain respects;

     NOW, THEREFORE, in consideration of the premises and for
other good and valuable consideration (the receipt and
sufficiency of which are hereby acknowledged), the parties hereto
agree as follows:

     SECTION 1       AMENDMENTS.  Effective on (and subject to the
occurrence of) the Fifth Amendment Effective Date (as defined
below):

     1.1_ Section 1.1 of the Credit Agreement shall be amended by
inserting the following definition in its appropriate
alphabetical position:

          Old Castle Transaction means the asset sale transaction
     contemplated by that certain Agreement of Purchase and Sale
     of Assets, dated as of March 30, 2001, by and among P&C,
     Inc.  and RM, Inc., as buyers, and Valley Asphalt, Inc.,
     Geodyne Beck Rock Products, Inc., Eagle Valley Materials,
     Inc. and Monroc, Inc., as sellers.

     1.2_ Section 3.1(b) of the Credit Agreement shall be amended by
inserting the following proviso at the end thereof:

     ; provided, however, the quarterly installment scheduled to
     be paid on March 31, 2001 may be deferred, but only to the
     earlier to occur of (i) April 13, 2001 and (ii) consummation
     of the Old Castle Transaction.

     1.3_ Section 6.1.1 of the Credit Agreement shall be amended by
inserting the following clause (c)

          (c)   Upon the application of the Available Cash
     Proceeds of the Old Castle Transaction to the Revolving
     Loans as set forth in Section 6.2.1(a), the Revolving
     Commitments shall automatically and permanently be reduced
     by the amount of such application.

     1.4_ Section 6.2.1(a) of the Credit Agreement shall be amended by
(i) inserting the words "and, as set forth in the next paragraph,
Revolving Loans" after the words "Term Loans" the first place
such words appear in the first sentence of such section and (ii)
deleting the last sentence of such section and inserting the
following in lieu thereof:

     If the Available Cash Proceeds of the Old Castle
     Transactions are greater than $22,000,000, then the Company
     shall retain $8,000,000 of such proceeds, but if such
     Available Cash Proceeds are less than $22,000,000, then the
     Company shall retain only an amount of such proceeds equal
     to the difference between (x) $8,000,000 and (y) the amount
     by which such Available Cash Proceeds are less than
     $22,000,000, and in each such instance, the balance of such
     Available Cash Proceeds, which shall constitute Designated
     Proceeds realized from the consummation of the Old Castle
     Transaction, shall be applied ratably to and in permanent
     reduction of the Revolving Loans, the Term A Loans, and the
     Term B Loans.  In all other cases, the Designated Proceeds
     of each Mandatory Prepayment Event shall be applied to the
     Term Loans and then, after the payment in full of the Term
     Loans, to the Revolving Loans.  All prepayments of Term
     Loans pursuant to this Section 6.2.1 shall be applied to the
     prepayment of the Term Loans pro rata among the Term A Loans
     and Term B Loans, with application to the remaining
     installments of each on a pro rata basis; provided that the
     application of proceeds of the Old Castle Transaction shall
     be applied, as to the Term A Loans, first to the installment
     of principal scheduled to be paid on March 31, 2001 to the
     extent of such installment and second to the remaining
     installments of the Term A Loans on a pro rata basis.

same effect as if made on and as of the Fifth Amendment Effective
Date (except to the extent relating solely to an earlier date, in
which case they were true and correct as of such earlier date);
(c) no Event of Default or Unmatured Event of Default exists,
other than the Known Existing Defaults, or will result from the

counterclaim or defense of any nature whatsoever to payment of
such obligations.
