                                                 footnotes on the following page


---------------

(1) The completion of all or any portion of the Offer is not a condition to the
    closing of the new senior subordinated notes offering or any of the other
    refinancing transactions. The lenders participating in our new senior credit
    facilities will require that we place in escrow, upon completion of the new
    senior subordinated notes offering, all of the net proceeds of the new
    senior subordinated notes offering and a portion of our borrowings under the
    term loan of our new senior credit facilities to pay the purchase price for
    debentures purchased in the Offer and to otherwise purchase or satisfy our
    repurchase obligations with respect to any untendered debentures. In
    addition, we may from time to time after the tenth business day after the
    expiration date of the Offer purchase any debentures not tendered in the
    Offer. We may acquire these debentures through open market purchases,
    privately negotiated transactions, tender offers, exchange offers or
    otherwise, upon such terms and at such prices as we may determine, which may
    be more or less than the price to be paid pursuant to the Offer and could be
    for cash or other consideration.

(2) The completion of all or any portion of the 6.80% notes tender offer is not
    a condition to the closing of the new senior subordinated notes offering or
    any of the other refinancing transactions. The amount of the term loan under
    the new senior credit facilities will be reduced on a dollar-for-dollar
    basis to the extent any 6.80% notes are not repurchased in the 6.80% notes
    tender offer. In addition, we may from time to time after the expiration
    date of the 6.80% notes tender offer purchase any 6.80% notes not tendered
    in the tender offer. We may acquire these notes through open market
    purchase, privately negotiated transactions, tender offers, exchange offers
    or otherwise, upon such terms and at such prices as we may determine, which
    may be more or less than the price to be paid pursuant to the 6.80% notes
    tender offer and could be for cash or other consideration.

(3) Includes restricted cash to be held in escrow to otherwise purchase or
    satisfy our repurchase obligations with respect to the untendered
    debentures. See note (1) above.

(4) We expect to be able to borrow up to $100.0 million under the revolving
    credit facilities. The revolving credit facilities will be available to us
    on a revolving basis during the period commencing on the closing date of the
    proposed new senior credit facilities and ending on the date that is five
    years after the closing date. We do not expect to draw down on the revolving
    credit facilities on the closing date.

(5) Represents borrowings on our draft facilities linked to depository accounts
    for certain of our subsidiaries.

(6) The refinancing of our existing revolving credit facilities will result in
    our expensing of previously capitalized deferred financing costs related to
    these facilities. The repurchase of both the 6.80% notes and the debentures
    will also result in a charge to our earnings equal to the unamortized
    deferred financing costs related to the 6.80% notes and the debentures and
    other expenses incurred in connection with the repurchases. Both of these
    charges will be reflected in other expense on our consolidated income
    statement. We have not reflected any gain or loss that may result from the
    repurchase of the 6.80% notes or the debentures. Any such gain or loss would
    also affect retained earnings and our consolidated income statement."
