have the respective meanings provided such terms in the Credit Agreement.

                          W I T N E S S E T H :

         WHEREAS, the Borrower, the Banks and the Administrative Agent are
parties to a Credit Agreement, dated as of December 15, 1998 (as in effect on

         WHEREAS, the Borrower has determined that it is in its best
interests to sell 100% of the capital stock of Scot, Incorporated, a
corporation organized under the laws of the State of Delaware ("Scot") and a
Wholly-Owned Domestic Subsidiary of the Borrower (the "Scot Sale");

         WHEREAS, to effectuate the Scot Sale, the Borrower and Scot have
heretofore entered into an Agreement and Plan of Merger, dated as of August

         WHEREAS, the Borrower has requested that the Banks consent to the

         WHEREAS, subject to the terms and conditions of this Amendment, the
Banks hereby agree to grant the consents, amendments and waivers under the
Credit Agreement as herein provided;

         NOW, THEREFORE, it is agreed:

I.  CONSENTS UNDER CREDIT AGREEMENT.

         1.  The Banks hereby consent to the Scot Sale, so long as (i) no
Default or Event of Default then exists or would result therefrom, (ii) such
sale is in an arm's-length transaction and the Borrower receives at least
fair market value (as determined in good faith by the Borrower), (iii) the
total consideration received therefrom by the Borrower is 100% cash and is
paid at the time of the closing of such sale, (iv) such consideration shall
be at least $55,400,000 and the Net Sale Proceeds therefrom shall be at least
$38,000,000, (v) 100% of the Net Sale Proceeds therefrom are applied upon
receipt thereof as a mandatory repayment of principal of outstanding Term
Loans in accordance with the requirements of Sections 4.02(h) and



(i) of the Credit Agreement (for avoidance of doubt, it is acknowledged and
agreed that no portion of such Net Sale Proceeds shall be permitted to be
reinvested pursuant to Section 4.02(d) of the Credit Agreement) and (vi) an
amount (the "Revolver Blocked Amount") equal to $11,500,000 of non-Net Sale
Proceeds from the Scot Sale is applied upon receipt thereof to prepay
outstanding Revolving Loans (with no corresponding reduction to the Total
Revolving Loan Commitment).  To the extent Collateral is sold in compliance
with the preceding provisions of this Section 1 of Part I, such Collateral
shall be sold free and clear of the Liens created by the respective Security
Documents and Scot also shall be released from its obligations under the
Subsidiaries Guaranty, and the Banks hereby authorize the Administrative
Agent and the Collateral Agent to take any actions deemed appropriate in
order to effect such releases.

         2.  In order to induce the Banks to grant the consent set forth in
preceding Section 1 of this Part I and notwithstanding anything to the
contrary contained in the Credit Agreement, the following limitations shall
apply:

        (i)  During the period commencing upon the consummation of the Scot
     Sale and continuing until such time as when the Borrower shall have paid
     its estimated tax payments with respect to both its federal and state
     income tax obligations for its fiscal year ending closest to October 31,
     2000 (which date shall not be earlier than January 15, 2001), (A) the
     Borrower may not incur any Revolving Loans, Swingline Loans or Letters
     of Credit if, after giving effect to the incurrence thereof, the
     aggregate outstanding principal amount of all Revolving Loans, Swingline
     Loans and Letter of Credit Outstandings would exceed the lesser of (x)
     the Total Revolving Loan Commitment as then in effect and (y) an amount
     equal to $20,000,000 LESS the Revolver Blocked Amount and (B) on any day
     on which the sum of the aggregate outstanding principal amount of all
     Revolving Loans, Swingline Loans and Letter of Credit Outstandings
     exceeds the lesser of (x) the Total Revolving Loan Commitment as then in
     effect and (y) an amount equal to $20,000,000 LESS the Revolver Blocked
     Amount, the Borrower shall prepay on such day the principal of Swingline
     Loans and, after all Swingline Loans have been repaid in full (or if no
     Swingline Loans are outstanding), Revolving Loans in an amount equal to
     such excess.  If, after giving effect to the prepayment of all
     outstanding Swingline Loans and Revolving Loans as contemplated by the
     immediately preceding sentence, the aggregate amount of the Letter of
     Credit Outstandings exceeds the lesser of (x) the Total Revolving Loan
     Commitment as then in effect and (y) an amount equal to $20,000,000 LESS
     the Revolver Blocked Amount, the Borrower shall pay to the
     Administrative Agent at the Payment Office on such day an amount of cash
     and/or Cash Equivalents equal to the amount of such excess (up to a
     maximum amount equal to the Letter of Credit Outstandings at such time),
     such cash and/or Cash Equivalents to be held as security for all
     obligations of the Borrower to the Issuing Bank and the Banks under the
     Credit Agreement in a cash collateral account to be established by the
     Administrative Agent.  The Banks hereby agree that, notwithstanding the
     existence or continuation of any Default or Event of Default (except as
     otherwise provided in clause (ii) below of the proviso), the Borrower
     shall at any time during the continuance of the limitations set forth in
     this Section 2(i) (but not before January 15, 2001) be permitted to
     incur Revolving Loans and Swingline Loans in an aggregate principal amount
     not exceeding the Revolver Blocked Amount PROVIDED that (i) the proceeds
     of such Revolving Loans and Swingline

                                      -2-


     Loans shall be promptly utilized by the Borrower for the sole purpose of
     satisfying its federal and state income tax obligations with respect to
     its fiscal year ending closest to October 31, 2000 and (ii) no Default
     or Event of Default under Section 10.01, 10.05, 10.10 or 10.11 of the
     Credit Agreement shall then exist; and

        (ii)  At all times after the Borrower shall have made its estimated
     tax payments with respect to its federal and state income tax
     obligations for its fiscal year ending closest to October 31, 2000
     (which date shall be no earlier than January 15, 2001) (at which time
     clause (i) above of this Section 2 of this Part I shall no longer be
     effective), unless the Required Banks shall have otherwise agreed in
     writing, (A) the Borrower may not incur any Revolving Loans, Swingline
     Loans or Letters of Credit if, after giving effect to the incurrence
     thereof, the aggregate outstanding principal amount of all Revolving
     Loans, Swingline Loans and Letter of Credit Outstandings would exceed
     the lesser of (x) the Total Revolving Loan Commitment as then in effect
     and (y) $20,000,000 and (B) on any day on which the sum of the aggregate
     outstanding principal amount of all Revolving Loans, Swingline Loans and
     Letter of Credit Outstandings exceeds the lesser of (x) the Total
     Revolving Loan Commitment as then in effect and (y) $20,000,000, the
     Borrower shall prepay on such day the principal of Swingline Loans and,
     after all Swingline Loans have been repaid in full (or if no Swingline
     Loans are outstanding), Revolving Loans in an amount equal to such
     excess.  If, after giving effect to the prepayment of all outstanding
     Swingline Loans and Revolving Loans as contemplated by the immediately
     preceding sentence, the aggregate amount of the Letter of Credit
     Outstandings exceeds the lesser of (x) the Total Revolving Loan
     Commitment as then in effect and (y) $20,000,000, the Borrower shall pay
     to the Administrative Agent at the Payment Office on such day an amount
     of cash and/or Cash Equivalents equal to the amount of such excess (up
     to a maximum amount equal to the Letter of Credit Outstandings at such
     time), such cash and/or Cash Equivalents to be held as security for all
     obligations of the Borrower to the Issuing Bank and the Banks under the
     Credit Agreement in a cash collateral account to be established by the
     Administrative Agent.

         3.  Notwithstanding anything to the contrary contained in the
Capital Call Agreement (as in effect prior to giving effect to this
Amendment), from and after the Fourth Amendment Effective Date (as defined
below), the Capital Call Agreement (as in effect prior to giving effect to
this Amendment) shall be terminated and of no further force or effect (it

apply in any respect to the new Capital Call Agreement entered into
