         In each row in the table set forth above, the first indicated rating
         corresponds to that assigned by S&P and the second indicated rating
         corresponds to that assigned by Moody's; the determination of which row

         of "Designated Rating".

                  "Consolidated Capitalization" means, as of any date of

         Capitalization shall be determined excluding any adjustment, non-cash
         charge to net income or other non-cash charges or writeoffs resulting
         thereto from application of SFAS No. 142.

                  "Consolidated Indebtedness" means, as of any date of
         determination, the sum of (i) the total Indebtedness as shown on the
         consolidated balance sheet of Borrower and its Consolidated
         Subsidiaries, determined without duplication of any Guarantee of
         Indebtedness of Borrower by any of its Consolidated Subsidiaries or of
         any Guarantee of Indebtedness of any such Consolidated Subsidiary by
         Borrower or any other Consolidated Subsidiary of Borrower, plus any
         Mandatory Payment Preferred Stock, less (ii) such amount of
         Indebtedness attributable to amounts then outstanding under receivables
         facilities or arrangements to the extent that such amounts would not
         have been shown as Indebtedness on a balance sheet prepared in
         accordance with GAAP prior to January 1, 1997, less (iii) if any
         Indexed Debt Securities the liabilities in respect of which as shown on
         the consolidated balance sheet of Borrower and its Consolidated
         Subsidiaries have increased from the amount of liabilities in respect
         thereof at the time of their issuance by reason of an increase in the
         price of the Indexed Asset relating thereto, the excess of (a) the
         aggregate amount of liabilities in respect of such Indexed Debt
         Securities at the time of determination over (b) the initial amount of
         liabilities in respect of such Indexed Debt Securities at the time of
         their issuance.

                  "Designated Rating" means (a) at any time that the Long -Term
         Debt Rating is assigned by both S&P and Moody's and such ratings are
         equivalent, such rating shall be the Designated Rating, (b) if clause
         (a) does not apply, (i) at any time that the Long -Term Debt Rating is
         issued by only one of S&P or Moody's, the rating of such debt issued by
         such Rating Agency shall be the Designated Rating, and (ii) at any time
         that such debt is rated by both S&P and Moody's, the lower of such
         ratings and (c) if neither (a) nor (b) apply, if the Long -Term Debt
         Rating is not assigned by either S&P or Moody's, the rating assigned to
         the senior unsecured long-term debt of Borrower shall be deemed to be
         the rating that is one level below the then current rating of the
         senior secured long-term debt of Borrower in accordance with clauses
         (a) and (b) above. Any change in the calculation of the Facility Fees
         or the Applicable Margin with respect to Borrower that is caused by a
         change in the Designated Rating will become effective on the date of
         the change in the Designated Rating. If the rating system of any Rating
         Agency shall change, or if either S&P or Moody's shall cease to be in
         the business of rating corporate debt obligations, Borrower and the
         Agent shall negotiate in good faith if necessary to amend this
         definition to reflect such changed rating system or the unavailability
         of ratings from such Rating Agencies and, pending the effectiveness of
         any such amendment, the Designated Rating shall be determined by
         reference to the rating most recently in effect prior to such change or
         cessation.

                  "Long-Term Debt Rating" means the rating assigned by a Rating
         Agency to the senior unsecured long-term debt of Borrower (it being
         understood that a change in outlook status (e.g., watch status,
         negative outlook status) is not a change in rating as contemplated
         hereby).

                  "Master Separation Agreement" means the master separation
         agreement, dated as of December 31, 2000, entered into between Borrower
         and Unregco providing for, among other things, the Spin-off, as
         amended, modified or supplemented from time to time.

                  "Moody's" means Moody's Investors Service, Inc., and any
         successor rating agency.

                  "Rating Agencies" means S&P and Moody's.

                  "S&P" means Standard & Poor's Ratings Group, and any successor
         rating agency.

                  "Spin-off" shall have the meaning specified in Schedule 8.04
         attached hereto.

                  "Supermajority Banks" means, at any time, Banks having at
         least 65% of the aggregate Commitments or, if the Commitments have been
         terminated, 65% of the aggregate Commitments in effect immediately
         prior to such termination.

                                       2

                  "Termination Date" means (a) initially October 10, 2002,
         unless the Majority Banks direct in writing on or prior to September 5,
         2002 that such Termination Date shall be September 10, 2002, in which
         case the Termination Date shall automatically be deemed to be September
         10, 2002, or (b) any earlier date on which (i) the Commitments have
         been terminated in accordance with this Agreement or (ii) all unpaid
         principal amounts of Loans hereunder have become due and payable in
         accordance with this Agreement.".

                  3. Amendment to Section 2.01 of the Credit Agreement (The
Committed Loans). Section 2.01 of the Credit Agreement is hereby amended by
adding at the end thereof the following:

                           "At a reasonable time at least one week prior to
                           September 5, 2002, the Agent shall inquire as to
                           whether requisite Banks intend to send the written
                           direction referred to in the definition of
                           Termination Date and shall notify the Borrower and
                           the Banks if the requisite number of such directives
                           have been received.".
