("Agent"), the Lenders signatory hereto, FRUIT OF THE LOOM, INC. ("Borrower"),
and FRUIT OF THE LOOM, LTD. and certain domestic Subsidiaries of Borrower

     WHEREAS, the parties hereto are parties to a Post-Petition Loan and
Security Agreement dated as of December 29, 1999 (as from time to time amended,
the "Loan Agreement"); and

          (f)  In Section 2.1, the definition of "Total Facility" is amended to
     reduce the amount thereof to $450,000,000 (reflecting a reduction of the

     Term Loan of $50,000,000).

          (g)  Each Lender's Revolving Loan Commitment and Total Commitment as
     set forth in Schedule 1.1 to the Loan Agreement shall be reduced by such

     forth for the last two measuring periods are amended and two additional
     measuring periods are added as follows:

                                                                 ---------------

                    December 31, 2000 to September 30, 2001         $65,000,000

                    December 31, 2000 to December 31, 2001          $75,000,000"

          (i)  In Section 9.25 (EBITDAR), two additional measuring periods are
     added as follows:

                    "Period                                      Minimum EBITDAR
                     ------                                      ---------------

                    December 31, 2000 to September 30, 2001        $102,991,000

                    December 31, 2000 to December 31, 2001         $128,445,000"

         contained in the preceding sentence will, from the Amendment No. 1
         Effective Date through the Maturity Date, prevail over any other

         to be outstanding hereunder and (ii) if and to the extent that the
         limitation contained in the preceding sentence is, for any reason,
         exceeded, the Borrower and the Canadian Borrower shall immediately

<PAGE>   19

                                      -19-

cause of action against any of the Banks, their predecessors or successors, or

the Administrative Agent wish to eliminate any possibility that any past

otherwise adversely affect any of the Banks' or the Administrative Agent's
rights, interests, contracts, collateral security or remedies. Therefore, each
of the Borrower, the Canadian Borrower and each of the Guarantors
unconditionally release, waive and forever discharge (A) any and all
liabilities, obligations, duties, promises or indebtedness of any kind of any of
the Banks, their predecessors and successors, and the Administrative Agent to

action, defense, circumstance or matter of any kind whatsoever which existed,
arose or occurred at any time prior to the date hereof.

         SS.8.    NO WAIVER. The Administrative Agent and each of the Banks
hereby expressly reserves all of their rights and remedies under the Credit
Agreement, the other related Loan Documents and applicable law in respect of any
and all Defaults or Events of Default under the Credit Agreement and the other
Loan Documents, other than with respect to the Specified Non-Compliance. Failure
of the Administrative Agent or any Bank to exercise any right or remedy shall
not constitute a waiver of that or any other right or remedy. Except as
expressly set forth in Section 2 hereof, nothing contained herein shall
constitute a waiver by the Administrative Agent or the Banks, or otherwise
entitle to the Borrower, the Canadian Borrower, or any Guarantor to a waiver, of
any existing or hereafter arising Default or Event of Default, nor shall the

under seal and shall be construed according to and governed by the laws of The
Commonwealth of Massachusetts.

         (c)      This Amendment may be executed in any number of counterparts
