     Level 4 pricing shall be effective from September 30, 1998, through the
     receipt of the Company's Compliance Certificate for the quarter ended
     December 31, 1998, unless a change in the Senior Public Debt Rating would
     require Level 5 pricing, and (B) thereafter, if the Company's Funded Debt
     to EBITDA ratio as reported on its Compliance Certificate equals or exceeds
     (a) 4:1, but is less than 4.50:1, Level 4 pricing shall apply, and (b)
     4.50:1, Level 5 pricing shall apply.  Any change in applicable rates or
     margins based on the Funded Debt to EBITDA ratio shall become effective the
     first day after receipt by the Banks of a Compliance Certificate indicating
     a Funded Debt to EBITDA ratio of greater than or equal to 4:1.  If at any

     to EBITDA ratio indicate two different levels of pricing, the higher of the
     two levels shall apply.

     3.           NEW (S)6.19. Section 6, "Representations and Warranties", is
                  ----------- 
hereby amended by adding a new Section 6.19 immediately after existing Section
6.18, as follows:

         (S)6.19. Year 2000 Compliance.  The Borrower and its Subsidiaries have
                  --------------------                                         
     reviewed the areas within their businesses and operations which could be
     adversely affected by, and have developed or are developing a program to
     address on a timely basis, the "year 2000 Problem" (i.e. the risk that
     computer applications used by the Borrower or any of its Subsidiaries may
     be unable to recognize and perform properly date-sensitive functions
     involving certain dates prior to and any date after December 31, 1999).
     Based upon such review, the Borrower reasonably believes that the "Year
     2000 Problem" will not have any materially adverse effect on the business
     or on the consolidated financial condition of the Borrower and its
     Subsidiaries.

     4.  AMENDMENT TO (S)7.18.  Section 7.18 is hereby amended by deleting it in
         --------------------                                                   
its entirety and replacing it with the following section:

         (S)7.18 Amendment of Note Purchase Agreement.  Metropolitan Life
         --------------------------------------------                    
     Insurance Company shall have: (a) agreed to amend its Note Purchase
     Agreement on terms which mirror or are no more restrictive than the Credit
     Agreement, as amended and (b) waived any default thereunder until the date
     of such amendment. Such amendment shall be in full force and effect no
     later than November 2, 1998.

     5.  AMENDMENT TO (S)8.4.  Section 8.4 is hereby amended by deleting it in
         -------------------                                                  
its entirety and replacing it with the following paragraph:

         Except as provided below, neither the Borrower nor any of its
     Subsidiaries will (a) declare or pay any Distributions, or (b) redeem,
     convert, retire or otherwise acquire shares of any class of its capital
     stock (other than in connection with a merger permitted by (S)8.3 hereof or
     conversion into another form of equity of any preferred shares of the
     Borrower existing as of the Closing Date pursuant to the terms thereof. If
     no Default or Event of Default has occurred and is continuing, or would be
     created as a result of such Distribution, (1) the Borrower and its
     Subsidiaries may declare or pay cash dividends and (2) the Borrower and its
     Subsidiaries may redeem, convert, retire, or otherwise acquire stock, so
     long as (A) the aggregate amount of all such Distributions, beginning
     September 30, 1998, do not exceed (i) $20,000,000 plus (ii) 50% of positive
                                                       ----                     
     Consolidated Net Income attributable to the fourth quarter of the year
     ending December 31, 1998, plus (iii) 50% of positive Consolidated Net
                               ---- 
     Income for each full year thereafter, and (B) with respect to Distributions
     under clause (2) above only, the ratio of Funded Debt to

<PAGE>
 
     EBITDA is less than 2.50:1, as reported in the most recent Compliance
     Certificate, and would remain less than 2.50:1, after giving effect to any
     Indebtedness to be incurred in connection with such Distribution.
     Notwithstanding the above, any Subsidiary may make Distributions to the
     Borrower and the Borrower agrees that neither the Borrower nor any
     Subsidiary will enter into any agreement restricting Distributions from
     such Subsidiary to the Borrower, and warrants that no such restriction is
     in effect as of the Closing Date, provided, that the provisions of this
                                       --------  
     sentence shall not apply to restrictions on the use or any Distribution of
     the proceeds of industrial development grants obtained by the Borrower's
     Subsidiary from any industrial development authority.

performance of the transactions contemplated hereby (i) are within the corporate
authority of the Borrower, (ii) have been duly authorized by all necessary
corporate proceedings on the part of the Borrower, (iii) do not conflict with or
result in any material breach or contravention of any provision of law, statute,

materially adversely affect the assets, business or any activity of the
Borrower, and (iv) do not conflict with any provision of the corporate charter

     (b)  The execution and delivery of this Second Amendment and the
performance of the transactions contemplated hereby will result in valid and

the Borrower in accordance with the respective terms and provisions hereof and
thereof, except as enforceability is limited by bankruptcy, insolvency,
reorganization, moratorium or other laws relating to or affecting generally the
enforcement of creditors rights and except to the extent that availability of
the remedy of specific performance or injunctive relief is subject to the
discretion of the court before which any proceeding therefor may be brought.

or in any document or instrument delivered pursuant to or in connection with the

as if made at and as of that time (except to the extent of changes resulting
from transactions contemplated or permitted by the Credit Agreement and by this
Second Amendment and changes occurring in the ordinary course of business which
singly or in the aggregate are not materially adverse, and to the extent that
such representations and warranties relate expressly and solely to an earlier
date).

     (e)  The Borrower has performed and complied with all terms and conditions
in the Credit Agreement and this Second Amendment required to be performed or
complied with by it prior to or at the Effective Date, and no Default or Event

modifications contained in this Second Amendment.

          ------------                                                         
counterparts and by different parties hereto on separate counterparts, each of
which when so executed and delivered shall be an original, but all of which
counterparts taken together shall be deemed to constitute one and the same
instrument.
