and each, a "Guarantor"), and MELLON BANK, N.A. (the "Bank"). Borrower and
Guarantors are sometimes collectively referred to herein as the "Obligors".

                                   BACKGROUND

    A. Pursuant to a certain Post-Petition Loan and Security Agreement dated
December 12, 1997 by and between Borrower and Bank as modified on February 24,
1998, March 4, 1998 and on March 9, 1998, (the "Loan Agreement"), Bank agreed,
subject to the terms and conditions stated therein, to extend to Borrower a line
of credit up to the maximum amount as defined therein (the "Line").

    B. By that certain Surety Agreement dated December 12, 1997, Guarantors
agreed to guarantee and become sureties for certain obligations of Borrower to
Bank, including those arising under the Loan Documents.

    C. Borrower has requested that Bank consent to the modification of certain
provisions of the Loan Agreement, which Bank is willing to do upon and subject
to the terms and conditions of this Amendment.

    D. All capitalized terms not defined herein shall have the meanings set
forth therefor in the Loan Agreement.

    NOW, THEREFORE, intending to be legally bound hereby, the parties hereto
agree as follows:

1.  ACKNOWLEDGE OF DEFAULTS. Borrower hereby confirms and acknowledges that it
    is in default of its respective obligations under the Loan Documents as a
    result, inter alia, of (a) Borrower's failure to achieve projected monthly
    sales as required in Article 13.1(c) of the Loan Agreement, and (b) Borrower
    exceeding the Inventory Sublimit, WIP Sublimit and Permitted Overadvance as
    originally scheduled under the Loan Agreement. Borrower further acknowledges
    and agrees that Bank has certain rights and remedies available to it as a
    result of the occurrence of such defaults, including the right to confess
    judgment against the Borrower and each Guarantor. BORROWER EXPRESSLY AGREES
    THAT NOTHING CONTAINED HEREIN SHALL BE DEEMED TO CONSTITUTE A WAIVER OR
    RELEASE OF ANY EXISTING EVENTS OF DEFAULTS OR OF ANY RIGHTS AND REMEDIES
    AVAILABLE TO BANK AS A RESULT THEREOF.

2.  MODIFICATIONS.

    The Loan Agreement shall be modified, effective as of the date hereof,
as follows:
