              or without Lender's knowledge or consent and whether made before
              or after an Event of Default), provided that if such excess is the

              made by the Lender to the Borrowers as of such date. From March

              amount of the Term Loan outstanding to Three Million Dollars
              ($3,000,000). To combine the obligations owed by the Borrowers to
              the Lender pursuant to the Initial Term Note and the December 2002
              Term Loan, the Borrowers have amended, restated and replaced the
              Initial Term Note with the Second Amended and Restated Term
              Promissory Note dated as of the date of the Ninth Amendment,
              issued in the initial principal amount of Three Million Dollars

              amounts, in accordance with this Agreement, the Term Promissory
              Note, and the other Financing Agreements, and (b) shall be secured
              by all the Collateral. The principal amount of the Term Loan shall

              earlier as provided herein) payable on the first day of each month
              commencing on February 1, 2003, of which, the first thirty-five
              (35) installments shall each be in the amount of $75,000 and the
              last installment shall be due on the Renewal Date and shall be in

              subject to the Maximum Credit and other applicable limits
              hereunder shall be subject to Lender's continuing right to
              establish and revise, in good faith, Availability Reserves,
              including, without limitation, Availability Reserves in an amount
              equal to the amount by which dilution with respect to GO/DAN's
              Accounts (as determined in accordance with Section 2.1(b)(i)(A))

              become effective as of the date set forth on the first page hereof
              and shall continue in full force and effect until December 27,
              2005 (the "Renewal Date"), and from year to year thereafter,
              unless sooner terminated pursuant to the terms hereof."

hereby is deleted in its entirety and the following is substituted in lieu
thereof:

                   "(c) If for any reason this Agreement is terminated prior to
              the end of the then current term or renewal term of this
              Agreement, in view of the impracticality and extreme difficulty of
              ascertaining actual damages and by mutual agreement of the parties
              as to a reasonable calculation of Lender's lost profits as a
              result thereof and as a result of Lender's willingness to
              foregoing certain fees that would otherwise be payable in a
              financing of this kind at the inception and during the term of
              this Agreement, Borrowers agree to pay to Lender, upon the
              effective date of such termination, an early termination fee in
              the amount set forth below if such termination is effective in the
              period indicated:


                          Amount                             Period
                          ------                             ------

              (i)   1% of Maximum Credit          from December 27, 2002 to and
                                                  including December 27, 2004;
                                                  and

              (iii) 0.5% of Maximum Credit        December 27, 2004 and
                                                  thereafter provided that this
                                                  provision shall not constitute
                                                  a commitment by Lender to
                                                  extend the term beyond the
                                                  Renewal Date.

                   Such early termination fee shall be presumed to be the amount
              of damages sustained by Lender as a result of such early
              termination and each Borrower agrees that it is reasonable under
              the circumstances currently existing. In addition, Lender shall be
              entitled to such early termination fee upon the occurrence of any
              Event of Default described in Sections 10.1(g) and 10.1(h) hereof,
              even if Lender does not exercise its right to terminate this
              Agreement, but elects, at its option, to provide financing to
              Borrowers or permit the use of cash collateral under the United
              States Bankruptcy Code. Lender agrees that if Borrowers refinance
              all of the Obligations with Wachovia Bank, National Association,
              the parent of the Lender, or if all of the Obligations are
              refinanced with the proceeds of an unsecured loan, each, at a time
              when no Event of Default has occurred and is continuing, the
              applicable early termination fee due Lender minus the portion of
              the early termination fee due the Participant(s) shall not be


                                      -6-
<PAGE>

              required to be paid. The early termination fee provided for in
              this Section 12.1 shall be deemed included in the Obligations."

         2. Fees.

              2.1. Line Increase Fee. Borrowers shall pay a line increase fee to
Lender, fully earned on the date hereof, in an amount equal to One Hundred
Twelve Thousand Five Hundred Dollars ($112,500) ("Line Increase Fee").

              2.2. Renewal Fee. Borrowers shall pay a renewal fee to Lender,
fully earned on the date hereof, in an amount equal to Two Hundred Fifty

hereof ("First Installment of Renewal Fee") and that One Hundred Twenty Five
Thousand Dollars ($125,000) of the Renewal Fee shall be payable one year after
the date hereof ("Second Installment of Renewal Fee").

         3. $5,000,000 Participant Loan. Lender will use good faith efforts to
place a $5,000,000 participation with a Participant satisfactory to the Lender
and the existing Participant(s). This participation shall reduce the amount of
Loans that Lender and the existing Participant(s) are obligated to make to the
Borrowers by an amount equal to the amount of the participation and in the
discretion of such new participant may be used to provide up to $5,000,000 (in
which Lender and existing Participant(s) will not participate) in a subline
collateralized with Borrowers' and their subsidiaries' Mexican assets subject to
documentation and such conditions as such new participant shall require.

         4. Consent.

              4.1. Consent to Acquisition of Assets. Subject to the terms and
conditions hereof and notwithstanding Section 6.6 of the Loan Agreement, Lender
hereby consents to the Borrowers' use of a portion of the proceeds of the Loans
