to the extent of the balance of such Net Available Cash after application in
accordance with clauses (A) and (B), to make an offer to purchase Securities
pursuant and subject to the conditions of this Indenture to the Holders at a
purchase price of 100% of the principal amount thereof plus accrued and unpaid

amount equal to the principal amount so prepaid, repaid or purchased.
Notwithstanding the foregoing provisions, the consideration received by the
Company and any Subsidiary in connection with the Asset Dispositions under the
