                                    (i)    at the Base Rate plus the Applicable
                                           Margin; or

                                    (ii)   at the reserve adjusted Eurodollar
                                           Rate plus the Applicable Margin; and

                          adjusted Eurodollar Rate" will have meanings customary
                          and appropriate for financings of this type; provided
                          that Base Rate shall be defined as the highest of (i)
                          the Administrative Agent's prime rate; (ii) the
                          Federal Funds rate plus 0.50% per annum; and (iii) the

                          interest periods for loans bearing interest at the
                          reserve adjusted Eurodollar Rate will be customary and
                          appropriate for financings of this type.

                          During the continuation of an event of default
                          interest on the loans and on all other amounts
                          outstanding under the Bridge Term Facility will accrue
                          at a rate equal to the rate on loans bearing interest
                          at the rate determined by reference to the Base Rate
                          plus an additional 2.00% per annum and will be payable
                          on demand.

                          The Applicable Margin shall equal the percentage
                          designated on Annex A hereto and based upon the
                          Borrower's Credit Ratings (as defined in Annex A) as
                          in effect from time to time.

                          The Borrower shall also pay the fees described on
                          Annex A.

Interest Payments:        Quarterly for loans bearing interest with reference to
                          the Base Rate; except as set forth below, on the last
                          day of selected interest periods (which will be one,
                          two or three months) for loans bearing interest with
                          reference to the reserve adjusted Eurodollar Rate; and
                          upon prepayment, in each case payable in arrears and
                          computed on the basis of a 360-day year (365/366 day
                          year with respect to loans bearing interest with
                          reference to the Base Rate).

                          the reserve adjusted Eurodollar Rate will be
                          prepayable only on the last day of the related

corresponding to such higher Borrower's Credit Rating.

"Borrower's Credit Ratings" means (a) the senior unsecured debt credit rating
and commercial paper credit rating of the Borrower from Moody's and (b) the long
