Re: Equity Commitment Letter

Ladies and Gentlemen:

Reference is made to the Agreement and Plan of Merger, dated as of even date herewith (as the same may be amended from time to time, the “Merger Agreement”), among Great Wolf Resorts, Inc. (the “Company”), a Delaware corporation, K-9 Holdings, Inc., a Delaware corporation (“Parent”) and K-9 Acquisition, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), pursuant to which Parent will acquire the Company by commencing a tender offer followed by a merger of Merger Sub, or a permitted assignee of Merger Sub, with and into the Company, on the terms and subject to the conditions set forth in the Merger Agreement. Capitalized terms herein used but not defined shall have the meanings ascribed to them in the Merger Agreement. This letter agreement is being delivered to Parent in connection with the execution of the Merger Agreement today by Parent, Merger Sub and the Company.

1. Commitment. This letter agreement confirms the commitment of each of the undersigned (each, an “Investor” and collectively, the “Investors”), severally and not jointly, and not jointly and severally, subject to the conditions set forth herein and in the Merger Agreement, to purchase, or to cause one or more of their respective affiliates to purchase, directly or indirectly, equity of Parent for the purpose of enabling (a) Parent to cause Merger Sub to accept for payment and pay for any and all shares of Common Stock tendered pursuant to the Tender Offer at the Acceptance Time (the “Offer Amount”) and (b) Parent to make the payments due under Sections 3.2(b) and 3.3(b) of the Merger Agreement at or immediately subsequent to the Effective Time (the “Merger Amount”), in each case, in an aggregate amount equal to the percentage of the Aggregate Commitment set forth opposite such Investor’s name on Exhibit A hereto (such amount with respect to each Investor is such Investor’s “Maximum Investor Commitment”); provided that no Investor shall, under any circumstances, be obligated to purchase equity from Parent or otherwise provide any funds to Parent in an amount exceeding the amount of such Investor’s Maximum Investor Commitment and the Investors, collectively,

shall not, under any circumstances, be obligated to purchase equity from Parent or otherwise provide any funds to Parent in an amount exceeding the Aggregate Commitment. The term “Aggregate Commitment” means an amount equal to: (i) $190,000,000; or (ii) such lesser amount as in the aggregate suffices to fully fund the Offer Amount and the Merger Amount pursuant to, and in accordance with, the Merger Agreement. Each Investor hereby confirms that it has unfunded capital commitments in an amount not less than such Investor’s Maximum Investor Commitment and no internal or other approval is required for such Investor to fulfill its obligations hereunder.

2. Termination. Each Investor’s obligation to fund its Maximum Investor Commitment is subject to the terms of this letter agreement and to (a) with respect to the Offer Amount, (i) the execution and delivery of the Merger Agreement by the Company, (ii) the satisfaction or waiver by Xxxxxx Sub or Parent of the Tender Offer Conditions, and (iii) the contemporaneous acceptance for payment by Merger Sub of all shares of Common Stock validly tendered and not validly withdrawn pursuant to the Tender Offer; and (b) with respect to the Merger Amount, (i) the execution and delivery of the Merger Agreement by the Company, (ii) the satisfaction or waiver by the Company, Merger Sub and Parent of all of the conditions set forth in Article VII of the Merger Agreement, and (iii) the closing of the Merger in accordance with the terms of the Merger Agreement. The obligation of each Investor to fund its Maximum Investor Commitment will terminate automatically and immediately upon the earliest to occur of (1) the consummation of the Closing, (2) a valid termination of the Merger Agreement in accordance with its terms, (3) the funding of the Aggregate Commitment, (4) the payment in full by the Investors of their Guaranteed Obligations (as defined in the Limited Guarantee) under the Limited Guarantee on the terms and subject to the conditions thereof, and (5) the assertion by the Company or any of its Affiliates of any claim against any Investor or any Related Party (as defined below), thereof in connection with this letter agreement, the Merger Agreement, the Limited Guarantee or any of the transactions contemplated hereby or thereby (including in respect of any oral representations made or alleged to be made in connection herewith or therewith), except with respect to any claim for specific performance or other equitable relief against Sponsor (as defined below) under the Confidentiality Agreement; provided, that with respect to clauses (4) and (5) of this Section 2, no such termination shall be effective if the Company or any of its Affiliates is seeking specific performance of Parent’s obligation to fund the Equity Financing pursuant to its rights under Section 9.17 of the Merger Agreement. Sections 3, 4, 5, 7, 8 and 9 hereof shall survive any such termination.

3. No Recourse. Notwithstanding anything that may be expressed or implied in this letter agreement, Parent, by its acceptance hereof, covenants, acknowledges and agrees that no Person other than the undersigned shall have any obligation hereunder and that, (a) notwithstanding that any of the undersigned may be a partnership or limited liability company, no recourse (whether at law, in equity, in contract, in tort or otherwise) hereunder or under any documents or instruments delivered in connection herewith, or in respect of any oral representations made or alleged to be made in connection herewith or therewith, shall be had against any former, current or future direct or indirect director, officer, employee, agent, partner, manager, member, securityholder, Affiliate, stockholder, controlling Person, assignee, Representative, Lender or other financing source of the undersigned, other than the undersigned, Parent, Merger Sub or their assignees under the Merger Agreement (any such Person, other than the undersigned, or Parent, Merger Sub or their assignees under the Merger Agreement, a “Related Party”), or any

Related Party of any of such undersigned’s Related Parties (including, without limitation, in respect of any liabilities or obligations arising under, or in connection with, this letter agreement or the transactions contemplated hereby (or in respect of any oral representations made or alleged to be made in connection herewith or therewith) or with respect to any Legal Action (whether at law, in equity, in contract, in tort or otherwise), including, without limitation, in the event Parent or Merger Sub breaches its obligations under the Merger Agreement and including whether or not Parent’s or Merger Sub’s breach is caused by the breach by any Investor of its obligations under this letter agreement) whether by the enforcement of any judgment or assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable Law; and (b) no personal liability whatsoever will attach to, be imposed on or otherwise incurred by any Related Party of any of the undersigned or any Related Party of any of the undersigned’s Related Parties under this letter agreement or any documents or instruments delivered in connection herewith (or in respect of any oral representations made or alleged to be made in connection herewith or therewith) or for any Legal Action (whether at law, in equity, in contract, in tort or otherwise) based on, in respect of, or by reason of such obligations hereunder or by their creation. Nothing in this letter agreement, express or implied, is intended to or shall confer upon any Person, other than Parent, the Company (as set forth in Section 5 hereof) and the undersigned, any right, benefit or remedy of any nature whatsoever under or by reason of this letter agreement.

4. Assignment; Reliance. This letter agreement, Parent’s rights hereunder and each Investor’s commitment hereunder shall not be assignable to any other Person without the prior written consent of the other parties hereto and the Company, and any attempted assignment without such consent shall be null and void and of no force and effect, except that (a) Parent may assign its rights hereunder to an assignee of Parent’s rights and obligations under the Merger Agreement made in accordance with the terms thereof or (b) each Investor may assign its commitments hereunder to an affiliate of such Investor; provided, however, that notwithstanding any such assignment, each Investor shall remain liable to perform all of its obligations hereunder. Each Investor acknowledges that the Company has entered into the Merger Agreement in reliance upon, among other things, the commitment set forth herein.

5. Binding Effect. This letter agreement may be relied upon only by Parent; provided that the Company may rely upon this letter as an express third party beneficiary, solely to the extent that the Company is awarded, in accordance with the conditions set forth in Section 9.17 of the Merger Agreement, specific performance of Parent’s obligation to cause the Equity Financing to be funded. Each Investor hereby waives (a) any defense to specific performance that a remedy at law would be adequate or that, absent specific performance, no irreparable harm would be suffered and (b) any requirement under applicable Law to post a bond or other security as a prerequisite to obtaining equitable relief. Except as set forth in the first sentence of this Section 5, nothing set forth in this letter agreement shall be construed to confer upon or give any Person other than Parent any benefits, rights or remedies under or by reason of, or any rights to enforce or cause Parent to enforce, the Aggregate Commitment or any Maximum Investor Commitment or any provisions of this letter agreement. Parent may only enforce this letter agreement at the direction of the Sponsor in its sole discretion, and Parent shall have no right to enforce this letter agreement unless directed to do so by the Sponsor in its sole discretion. Parent’s creditors shall have no right to enforce this letter agreement or to cause Parent to enforce this letter agreement. For purposes of this letter agreement, “Sponsor” shall mean Apollo Management VII, L.P. For
