                         FIFTH AMENDMENT AND WAIVER TO
                          LOAN AND SECURITY AGREEMENT


          This Fifth Amendment and Waiver to Loan and Security Agreement (this
"Amendment"), is made and entered into effective as of the 14th day of May, 1998
by and between FINOVA CAPITAL CORPORATION, a Delaware corporation ("Lender") and
AMERITRUCK DISTRIBUTION CORP., a Delaware corporation ("Borrower").  This
Amendment modifies and amends that certain Loan and Security Agreement, dated
May 5, 1997, between Lender and Borrower (the "Agreement").  All terms used
herein with initial capital letters, unless otherwise specifically defined
herein, shall have the same meanings as set forth in the Agreement.  All
references to the Agreement shall include the Schedule.

                               R E C I T A L S:

          WHEREAS, Borrower has informed Lender that Borrower is attempting to
obtain Twenty Million Dollars ($20,000,000) in connection with a private
placement of its capital stock or indebtedness;

          WHEREAS, Borrower has also informed Lender that Events of Default
exist as a result of a breach of the Current Ratio, Net Worth, Debt Service
Coverage Ratio and Operating Ratio set forth in Section 13.14 of the Agreement
for the period ending March 31, 1998 (the "March 31 Events of Default");

          WHEREAS, in connection therewith, Borrower has requested that Lender
waive the March 31 Events of Default, and Borrower and Lender desire to amend
the Agreement in certain respects;

          WHEREAS, such amendments to the Agreement will provide Borrower with
additional loans;

          NOW, THEREFORE, in consideration of the foregoing premises and other
valuable consideration, the parties hereto agree as follows:

          1. Waiver. Lender hereby waives the March 31 Events of Default. The
             ------        
waiver of the March 31 Events of Default shall not constitute a waiver of any
other Events of Default which may exist or hereafter arise under the Agreement
or any of the other Loan Documents or an agreement by Lender to waive any other
Events of Default. Without limiting the foregoing, Borrower's failure to comply
with the covenants contained in Section 13.14 for any period ending after March
31, 1998 shall constitute an Event of Default.
