                  September 30, 1998 quarter, including the effects thereof on
                  the Borrower's financial statements for the December 31, 1998
                  quarter, being waived as provided in the Original Waiver, as

                  for the December 31, 1998 quarter as reflected in the
                  Borrower's financial statements for that period, and/or (c)
                  any ratios or other computations or certifications required to
                  be made, maintained or provided under the Agreement or any
                  other Loan Document (as used in this Waiver, such term shall
                  include, in addition to the documents specified in the
                  definition thereof in the Agreement, the Original Waiver)
                  based upon or in respect of any of the financial statements
                  referenced in the immediately foregoing clauses (a) and (b).

                           (iii) The Required Lenders hereby waive, for and

                  for the delivery of quarterly financial statements and the
                  associated Compliance Certificate (provided that the Borrower
                  shall, and the Borrower hereby agrees to, deliver the same
                  within five (5) days after its filing of a Quarterly Report on
                  Form 10-Q including such quarterly financial statements) and
                  any Defaults or Events of Default under Section 7.7 currently

                  Defaults or Events of Default hereafter arising solely by
                  reason of any financial statements and/or certifications or
                  other similar documents based thereon or relating thereto
                  required to be provided by the Borrower under the Agreement or

         Unless otherwise agreed to by the Required Lenders in writing, upon the
         expiration of the Extended Waiver Period, the waivers provided for
         herein shall be of no further force or effect, and unless as of that
         time the Borrower is then in compliance with all of the provisions of
         the Agreement compliance with which is waived in the Original Waiver
         and in this Waiver, an Event of Default shall exist, and the Lenders
         may exercise any and all rights and remedies available to any of them
         under the Agreement, the other Loan Documents or applicable law.

                  2. AGREEMENTS BY THE BORROWER. Anything in the Agreement to
         the contrary notwithstanding, in consideration of the waivers set forth
         above, the Borrower hereby agrees as follows during the Extended Waiver
         Period:

                           (i) The obligations of the Borrower under Section 2
                  of the Original Waiver, except as the same may be modified by
                  the terms of this Waiver, shall not be limited to the Waiver
                  Period but shall, as so modified, continue to be performed and
                  observed by the Borrower for and during the Extended Waiver
                  Period.

                           (ii) Unless otherwise agreed to by the Required
                  Lenders in writing, the Borrower agrees that the maximum
                  permitted Aggregate Revolving Credit Exposure shall continue
                  to be determined in accordance with the formula for
                  determining the same set forth in Section 2(i) of the Original
                  Waiver, except that the Sixty Million Dollar ($60,000,000)
                  amount stated in Section 2(i) of the Original Waiver shall
                  hereby be reduced to Fifty-Five Million Dollars ($55,000,000)
                  (such sum being the principal amount of indebtedness presently
                  outstanding under the Agreement), and that it will not request
                  any new Loans or the issuance of any new Letters of Credit
                  under the Agreement.

                  The Borrower agrees that any violation of its agreements set
         forth above shall constitute a Default under the Agreement. Unless
         otherwise agreed to in writing by the Borrower, the foregoing
         agreements of the Borrower shall be of no further force or effect upon
         the expiration of the Extended Waiver Period.

                  3. EFFECTIVE DATE. Paragraph 1 and 2 of this Waiver shall not
         be effective until such date (the "Effective Date") as each of the
         following conditions shall have been satisfied:

                           (i) The Agent or the Borrower shall have received
                  counterparts of this Amendment executed by the Required
                  Lenders and the current Guarantors.

                           (ii) The Borrower shall have paid the reasonable fees
                  and disbursements of Special Counsel which shall have accrued
                  up to, and properly invoiced to the Borrower no later than,
                  the Effective Date.

                           (iii) On and as of the Effective Date after giving
                  effect to this Waiver, there shall exist no Default or Event
                  of Default, and all of the representations and warranties of
                  the Loan Parties contained in the Loan Documents (in the case
                  of the affirmation of representations and warranties in
                  Section 4(c) of the Original Waiver, after giving effect to
                  this Waiver in addition to the Original Waiver as there
                  recited) shall be true and correct with the same effect as
                  though such representations and warranties had been made on
                  the Effective Date.

                           (iv) Bank One shall have consented to the waivers and
                  agreements contemplated hereby with respect to the Bank One
                  Credit Line.

                           (v) The Borrower shall have paid to each Lender that
                  has executed a counterpart of this Waiver on or prior to the
                  Effective Date a consent fee equal to 0.25% of such Lender's
                  Revolving Commitment Amount (after giving effect to the
                  reduction in the Aggregate Revolving Commitment Amount
                  referred to in Section 3(iv) of the Original Waiver).

                  4. AFFIRMATION. On each of the date hereof and the Effective
         Date, the Borrower hereby (a) reaffirms and admits the validity and
         (subject to the terms of the Original Waiver and this Waiver)
         enforceability of the Loan Documents and all of its obligations
         thereunder, (b) agrees and admits that it has no defenses to or offsets
         against any such obligations, and (c) represents and warrants that
         after giving effect hereto and to the Original Waiver (as modified
         hereby), no Default or Event of Default has occurred and is continuing,
         and

                                       4
<PAGE>   5

         that each of the representations and warranties made by it in the
         Agreement is true and correct with the same effect as though such
         representation and warranty had been made on such date.

                  5. WAIVERS LIMITED. In all other respects, the Loan Documents
         shall remain in full force and effect, and no waiver or amendment in
         respect of any term or condition of any Loan Document contained herein
         shall be deemed to be a waiver or amendment in respect of any other
         term or condition contained in any Loan Document.

                  6. COUNTERPARTS. This Waiver may be executed in any number of
         counterparts all of which, taken together shall constitute one waiver.
         In making proof of this waiver, it shall only be necessary to produce
         the counterpart executed and delivered by the party to be charged.

                  7. GOVERNING LAW. THIS WAIVER IS BEING EXECUTED AND DELIVERED
         IN, AND IS INTENDED TO BE PERFORMED IN, THE STATE OF NEW YORK AND SHALL
         BE CONSTRUED AND ENFORCEABLE IN ACCORDANCE WITH, AND BE GOVERNED BY,
         THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO
         PRINCIPLES OF CONFLICT OF LAWS.

                  AS EVIDENCE of the agreement by the parties hereto to the
terms and conditions herein contained, each such party has caused this Waiver to
be executed on its behalf.
