consistent basis; and

                                    (b)      commencing with the first fiscal

not later than forty-five (45) days after the end of each of the first three
fiscal quarters of each fiscal year, the unaudited consolidated balance sheet

approval of a majority of the Independent Directors then serving on the Board
of Directors.

first give written notice to the Company of the approximate amount of debt
securities it intends to purchase and the general time period within which it

greater than ninety (90) days (the "Specified Period"). The Company shall have

faith intention to purchase such amount of debt securities within the Specified

Subsidiaries (other than the Company and its Subsidiaries) not to, purchase any
such debt securities within the Specified Time Period and shall thereafter
comply with the provisions of this Section 4.3 prior to any subsequent purchase
of any debt securities issued under the TWE Indenture. If the Company does not
indicate its good faith intention to purchase such debt securities, AOLTW shall
be entitled to proceed with its purchase of debt securities for the duration of
the Specified Time Period.
