OPTIONAL REDEMPTION:     For so long as they are held by the Purchasers, the
                         Rollover Notes will be redeemable at the option of the
                         Company, in whole or in part, at any time at par plus
                         accrued and unpaid interest to the redemption date;
                         provided, however, that if the Rollover Notes are sold

                         basis no less favorable to the Company than the then
                         applicable rate of interest (it being understood that
                         the Purchasers shall have the right to unilaterally
                         fix the Interest Rate on the Rollover Notes in
                         conjunction with such third party sales and it also
                         being understood that no such third party sales shall
                         take place unless the Company has been given 30 days'
                         prior notice), the Rollover Notes will be non-callable
                         for 5 years from the date of issuance and will be
                         callable thereafter at par plus accrued interest plus
                         a premium equal to 50% of the coupon in effect on the
                         date of issuance of the Rollover Notes, declining
                         ratably on each yearly anniversary to par one year
                         prior to the maturity of the Rollover Notes.

                         conditions, the Rollover Notes upon any

                         as practicable after the issuance of the Rollover
                         Notes.  The Company will keep the registration
                         statement for the Rollover Notes effective until the
                         Rollover Notes shall have been redeemed.  If a "shelf"
                         registration statement for the Rollover Notes has
                         either (i) not been filed within 60 days from the date
                         of issuance of the Rollover Notes, or (ii) not been
                         declared effective within 120 days from the date of
                         issuance of the Rollover Notes, the Company will pay
                         liquidated damages of $.192 per week per $1,000
                         principal amount of Rollover Notes until such time as
                         such registration statement has become effective.  The
                         Company will also pay such liquidated damages for any
                         period of time following the effectiveness of such
                         registration statement that the registration statement
                         is not available for

                         the registration of any debt securities which are
                         registered by the Company unless all of the Rollover
