therein.

         Section 2.  Amendments.  Subject to the satisfaction of the conditions
precedent specified in Section 5 below, but effective as of the date hereof,
the Credit Agreement shall be amended as follows:

         2.01.  References in the Credit Agreement (including references to the
Credit Agreement as amended hereby) to "this Agreement" (and indirect
references such as "hereunder", "hereby", "herein" and "hereof") shall be
deemed to be references to the Credit Agreement as amended hereby.  References

         to the Agent of a certificate of a senior financial officer of the
         Company demonstrating such fact prior to the end of the next
         succeeding fiscal quarter (accompanied by the financial statements
         required to be delivered pursuant to Section 9.01(a) or 9.01(b), as
         the case may be, hereof), the "Applicable Margin" for each Loan shall
         be reduced to the rate for the respective Type of Loan set forth
         opposite such range in the schedule below during the period commencing
         on the Quarterly Date on or immediately following the date of receipt
         of such certificate to but not including the next succeeding Quarterly
         Date thereafter (except that notwithstanding the foregoing, if an
         Event of Default shall have occurred and be continuing at the time of
         delivery of such certificate or at any time following the same until
         such next succeeding Quarterly Date, and the Agent acting on the
         instructions of the Majority Banks shall have notified the Company
         that this proviso shall not apply, the Applicable Margin for any such
         Loan shall not as a consequence of this proviso be so reduced for the
         period from and including the date of such notice to but excluding the
         date such Event of Default shall have been cured to the reasonable
         satisfaction of the Agent or the Majority Banks):

         Business Day of a calendar month (or on any day for which there is no
         numerically corresponding day in the appropriate subsequent calendar
         month) shall end on the last Business Day of the appropriate
         subsequent calendar month.  Notwithstanding the foregoing:  (i) if any
         Interest Period for any Revolving Credit Loan would otherwise end
         after the Revolving Credit Termination Date, such Interest Period
         shall end on the Revolving Credit Termination Date; (ii) no Interest
         Period for any Term Loan may commence before and end after any
         Principal Payment Date unless, after giving effect thereto, the
         aggregate principal amount of the Term Loans having Interest Periods
         that end after such Principal Payment Date shall be equal to or less
         than the aggregate principal amount of the Term Loans scheduled to be
         outstanding after giving effect to the payments of principal required
         to be made on such Principal Payment Date; (iii) each Interest Period
         that would otherwise end on a day which is not a Business Day shall

         aggregate principal or face amount at any one time outstanding up to
         but not exceeding the amount set opposite such Bank's name on Annex 1
         hereto under the caption "Revolving Credit Commitment" (as the same
         may be reduced at any time or from time to time pursuant to Section

         Termination Date.  In the event that on the Revolving Credit
         Termination Date there are outstanding Letter of Credit Liabilities,
         the Company shall be required to provide cover for such Letter of
         Credit Liabilities in an amount equal to the aggregate face amount of
         the outstanding Letter of Credit Liabilities.  The Company shall

         an amount equal to the required amount, which funds shall be retained
         by the Agent in the Collateral Account (as provided therein as
         collateral security in the first instance for the Letter of Credit
         Liabilities) until such time as the Letters of Credit shall have been

         of its chief financial officer certifying as to the foregoing and
         setting forth a calculation demonstrating that the ratio set forth in
         the first paragraph of Section 1009 of the Indenture, after giving
         effect to such borrowing or issuance, shall be less than 5.5 to 1."

         2.09.  Section 9.13 of the Credit Agreement shall be amended by
replacing "$10,000,000" with "$15,000,000".

         2.10    The Credit Agreement shall be amended by inserting as Annex 1

than the Banks and the Agent) hereby represents and warrants to the Banks and
the Agent that the representations and warranties made by such party in each

warranties to the Credit Agreement included reference to the Credit Agreement
as amended by this Seventh Amendment.

amendments to the Credit Agreement set forth in said Section 2 shall become
effective, as of the date hereof, upon the satisfaction of the following
conditions precedent:

         5.01.  Execution by All Parties.  This Seventh Amendment shall have
been executed and delivered by each of the parties hereto.

         5.02.  Notes and Initial Loans.  The Company shall have delivered to

delivered to such Bank pursuant to Section 2.08 of the Credit Agreement, a new
Revolving Credit Note of the Company in substantially the form of Exhibit A-1
to the Credit Agreement, dated the date of the Revolving Credit Note being
exchanged, payable to such Bank in a principal amount equal to its Revolving
Credit Commitment (as increased hereby) and otherwise duly completed, and each

Increasing Banks shall constitute a "Revolving Credit Note" under the Credit
Agreement as amended hereby.

         to the Credit Agreement) and of all corporate authority for each
         Obligor (including, without limitation, board of director resolutions
         and evidence of the incumbency of officers for each Obligor) with

         Obligor to the contrary).

                 (2)      Opinion of Counsel to the Obligors.  An opinion of
         Kean, Miller, Hawthorne, D'Armond, McCowan & Jarman, L.L.P., counsel

Agreement set forth in Section 2 above shall become effective, the Company,
without regard to the provisions of Section 4.02 of the Credit Agreement, shall
