and (E) thereto, to read as follows:

                      (d) LOAN ACCOUNTS. The Loans made by each Bank shall be
        evidenced by one or more accounts or records maintained by such Bank in
        the ordinary course of business. The accounts or records maintained by
        the Administrative Agent and each Bank shall be prima facie evidence of
        the amount of the Loans made by the Banks to each Borrower and the
        interest and payments thereon. Any failure so to record or any error in
        doing so shall not, however, limit or otherwise affect the obligation of
        any Borrower hereunder to pay any amount owing by such Borrower with
        respect to the Loans made to such Borrower.

                      (e) NOTES. Upon the request of any Bank made through the
        Administrative Agent, the Revolving Loans made by such Bank may be
        evidenced by one or more Revolving Credit Notes, instead of or in
        addition to loan accounts. Each Bank may endorse on the schedules
        annexed to its Note(s) the date, amount and maturity of each Loan made
        by it and the amount of each payment of principal made by or on behalf
        of the relevant Borrower with respect thereto. Such Bank's endorsement
        shall be prima facie evidence as to such matters; PROVIDED, HOWEVER,
        that the failure of a Bank to make, or an error in making, a notation
        thereon with respect to any Loan shall not limit or otherwise affect the
        obligations of the Borrowers hereunder or under any such Note to such
        Bank.

               (b) SECTION 2.02 is hereby amended in its entirety to read as
follows:

               2.02 CERTAIN PRICING TERMS. The Applicable Margin and the
        Commitment Fee, at any time, shall be equal to the applicable number of
        Basis Points per annum specified in SCHEDULE 2.02 hereto in the column
        identified by the Level (a "Level") corresponding to the applicable
        Ratings assigned at such time by the Rating Agencies; provided, however,
        that (a) if different Ratings are assigned by S&P and Moody's and the
        Ratings are only one Level apart, then the pricing shall be determined
        based on the higher of the two Ratings, and (b) if different Ratings are
        assigned by S&P and Moody's and the Ratings are more than one Level
        apart, then the pricing shall be at the Level which is one Level higher
        than the lower of the two Ratings. If any Rating established by a Rating
        Agency shall be changed, such change shall be effective for purposes of
        determining the Applicable 

                                      -3-
<PAGE>
        Margin and the Commitment Fee hereunder as of the date on which such
        change is first announced by the applicable Rating Agency. The Company
        shall give prompt written notice to the Administrative Agent of any
        changes to any Ratings. As used herein, "Basis Point" means one
        one-hundredth of one percent (1/100th of 1%).

        (c) The first sentence of SUBSECTION 2.09(B) is hereby amended to read
in its entirety as follows:

               The Company shall also pay to the Administrative Agent for the
        account of each Bank a fee ("Commitment Fee") on the average daily
        unused portion of such Bank's Commitment, computed on a quarterly basis
        in arrears on the last Business Day of each calendar quarter based upon
        the daily utilization for that quarter as calculated by the
        Administrative Agent, equal to the applicable number of Basis Points per
        annum determined in accordance with SECTION 2.02 by reference to
        SCHEDULE 2.02.

        1.3 AMENDMENTS TO ARTICLE IV. The following new SECTION 4.03 is added to
