(4)           the first date upon which Great Wolf Resorts ceases to own directly or indirectly 100% of the Equity Interests in the Company;

(5) Great Wolf Resorts or the Company consolidates with, or merges with or into, any Person, or any Person consolidates with, or merges with or into, Great Wolf Resorts or the Company, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of Great Wolf Resorts or the Company or such other Person is converted into or exchanged for cash, securities or other property, other than any such transaction where the Voting Stock of Great Wolf Resorts or the Company outstanding immediately prior to such transaction constitutes or is converted into or exchanged for a majority of the outstanding shares of the Voting Stock of such surviving or transferee Person (immediately after giving effect to such transaction); or

(6) the first day on which a majority of the members of the Board of Directors of Great Wolf Resorts are not Continuing Directors.

3

Agreement or (ii) thereafter, any direct or indirect changes to the internal organization or management structure of Apollo Global Management, LLC or Apollo Management Holdings GP, LLC or their related investment funds, alternative investment vehicles and managers, and accordingly, no Change of Control Offer shall be required to be made under Section 4.17 or any other provision of the Indenture; and (E) a “Person” or “group” shall not be deemed to have beneficial ownership of securities subject to a stock purchase agreement, merger agreement or similar agreement (or voting or option agreement related thereto) until the consummation of the transactions contemplated by such agreement.
