                        (e) Limit on Revolving Credit Loans and Letters of
                Credit Outstanding. After giving effect to any Revolving Credit
                Loan to be made or Letters of Credit to be issued on such date,
                the aggregate outstanding Revolving Credit Loans and Letter of
                Credit Outstanding shall not exceed $76,000,000 unless
                Subordinated Revolving Loans (including for this purpose
                Subordinated Revolving Loans converted into Subordinated Term
                Loans) are outstanding in a principal amount of at least
                $30,000,000.

        1.7 SIMA Letter of Credit. A new subsection 8.16 is added to the Credit
Agreement to read as follows:

                        8.16 SIMA Letter of Credit. If SIMA fails to make a
                Subordinated Revolving Loan within 10 days after the Borrower's
                request, the Borrower shall promptly notify the Agent and the
                Lenders in writing of such failure, and deliver to the Agent
                written instructions to make a drawing on the SIMA Letter of
                Credit in the amount of the Subordinated Revolving Loans
                requested by the Borrower and not funded by SIMA. The Agent
                shall be irrevocably authorized and empowered to make a drawing
                under the SIMA Letter of Credit within 5 days after receipt of
                the Borrower's written instructions by an officer of the Agent
                responsible for administering this Agreement. Notwithstanding
                the foregoing, in the event that (i) the Borrower fails to make
                such request for Subordinated Revolving Loans or (ii) SIMA fails
                to make such Subordinated Revolving Loans in accordance with the
                Subordinated Debt Documents, and in either instance such failure
                continues for more than ten (10) days after the date the
                Borrower delivers or is required to deliver its financial
                statements (either quarterly or annual) for such period to the
                Agent pursuant to subsection 8.1, the Borrower shall be deemed
                to have automatically and irrevocably instructed the Agent under
                this subsection 8.16 to make a drawing under the SIMA Letter of
                Credit to fund Subordinated Revolving Loans in an amount
                required to be made by the Borrower pursuant to the last
                sentence of Section 8.17. All funds received as a result of any
                such drawing shall be promptly remitted to the Borrower and
                shall constitute Subordinated Revolving Loans. The Agent shall
                have no obligation with respect to the SIMA Letter of Credit
                except to make a drawing thereon if and to the extent set forth
                in this subsection 8.16, and to consent to amendments to such
                Letter of Credit to reduce the face amount thereof by an amount
                equal to all Subordinated Revolving Loans converted to
                Subordinated Term Loans.

        1.8 Conversion of Subordinated Revolving Loans to Subordinated Term
Loans. A new subsection 8.17 is added to the Credit Agreement to read as
follows:

                        8.17 Conversion of Subordinated Revolving Loans to
                Subordinated Term Loans. Convert a portion of the outstanding
                principal balance of the Subordinated Revolving Loans
                (calculated as set forth below) into the Subordinated Term
                Loans, effective as of the last day of a fiscal quarter, if at
                the end of any such fiscal quarter ending on or prior to March
                31, 2001, the Consolidated EBITDA for the Borrower and its
                consolidated Subsidiaries for the four quarters then ending is
                less than the amount required under subsection 9.1(e). Such
                conversion shall be automatic and be effected by adding the
                applicable amount to the outstanding principal balance of the
                Subordinated Term Loan.

                                       4
<PAGE>

                The amount to be converted for each fiscal  quarter shall be the
                difference between the Projected EBITDA for the Borrower and its
                Subsidiaries  for such 12 month  period  shown in the  following
                schedule:

                                                 Projected
                    Quarter                        EBITDA
                    -------                        ------
                    12/31/99                    $30,190,000
                    3/31/00                      30,570,000
                    6/30/00                      30,240,000

                    12/31/00                     54,930,000
                    3/31/01                      67,980,000

                and the actual Consolidated EBITDA for the Borrower and its
        consolidated Subsidiaries for such 12 month period. If the amount to be
        converted exceeds the outstanding principal balance of the Subordinated
        Revolving Loans, the Borrower shall borrow additional Subordinated
        Revolving Loans to the extent necessary to fund the converted amount,
        until SIMA's entire $30,000,000 commitment to make Subordinated
        Revolving Loans has been funded.

        1.9 Financial Condition Covenants. Subsection 9.1 of the Credit
Agreement is amended (a) to provide that the financial covenants set forth in
subsections (a) through (d) of subsection 9.1 will not be in effect or tested on

31, 2000 or March 31, 2001, and (b) to add the following subsection (e):

                Consolidated EBITDA of the Borrower and its consolidated
                Subsidiaries for any period of four consecutive fiscal quarters
                ending on a date specified below plus (ii) the principal amount
                of all Subordinated Revolving Loans which are converted into
                Subordinated Term Loans in respect of such period in accordance
                with subsection 8.17 hereof to be less than the amount set forth
                opposite such period below:
