EXECUTION VERSION

Consulting Agreement

CONSULTING AGREEMENT dated as of August 13, 2012 (this “Agreement”), between GWR OPERATING PARTNERSHIP, L.L.L.P., a Delaware Limited Liability Limited Partnership (“GWROP”), GREAT WOLF RESORTS, INC., a Delaware Corporation (“GWRI”) and APOLLO MANAGEMENT VII, L.P., a Delaware limited partnership (“Apollo”).

GWROP desires to avail itself of Apollo’s and/or its Affiliates expertise and consequently has requested that Apollo make such expertise available from time to time in rendering certain consulting and investment advisory services related to the business and affairs of GWROP and its Affiliates. Apollo, GWROP and GWRI agree that it is in their respective best interests to enter into this Agreement. It is the intention of the parties that this Agreement is not for services in connection with the day-to-day business affairs of GWROP or its Affiliates.

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth, GWROP, GWRI and Apollo agree as follows:

Section 1. Retention of Apollo.

GWROP hereby retains Apollo, and Apollo accepts such retention, upon the terms and conditions set forth in this Agreement.

Section 2. Term.

This Agreement shall commence effective as of May 4, 2012 and shall remain in effect until the earliest of (i) the twelfth anniversary of the date hereof, (ii) such time as Apollo and its Affiliates then owning, directly or indirectly, beneficial economic interests in GWROP own in the aggregate, directly or indirectly, less than 5% of the beneficial economic interest of GWROP and (iii) such earlier date as is mutually agreed upon by GWROP, GWRI and Apollo (the “Term”). In the event of termination or expiration of this Agreement in accordance with this Section 2, this Agreement shall immediately become void and have no effect without any further liability or obligation on the part of any party hereto; provided, however, the following Sections shall survive the termination of this Agreement: Sections 7 through 15 and any accrued but unpaid obligations of GWROP or GWRI to pay fees and/or expenses hereunder.

Section 3. Services.

(a) Apollo shall, or shall at its option cause one or more Affiliates to, advise GWROP and its Subsidiaries (and at GWROP’s request, its Affiliates) concerning such matters that relate to GWROP’s business strategies, proposed financial transactions, acquisitions, divestitures, investments and other financial related matters of GWROP and its Affiliates, in each case as GWROP shall reasonably and specifically request by way of notice to Apollo, which notice shall specify the services required of Apollo and shall include all background material necessary for Apollo to complete (or cause to be completed) such services. If requested to provide such services, Apollo shall, or shall cause at its option one or more Affiliates to, devote such time to any such written request as Apollo shall deem, in its discretion, necessary. Such consulting services, in Apollo’s

discretion, shall be rendered in person or by telephone or other communication. Apollo shall have no obligation to GWROP as to the manner and time of rendering its or its Affiliates services hereunder, and GWROP shall not have any right to dictate or direct the details of the services rendered hereunder.

(b) Apollo shall, or shall cause an Affiliate to, perform all services to be provided hereunder as an independent contractor to the GWROP and not as an employee, agent or representative of GWROP. Apollo shall have no authority to act for or to bind GWROP without its prior written consent.

(c) This Agreement shall in no way prohibit Apollo or any of its partners or Affiliates or any director, officer, partner or employee of Apollo or any of its partners or Affiliates from engaging in other activities, whether or not competitive with any business of GWROP or any of its respective subsidiaries or Affiliates.

Section 4. Compensation.

(a) Management Fee. As consideration for Apollo’s agreement to render (or cause to be rendered) the services set forth in Section 3(a) and as compensation for any such services rendered by Apollo or any of its Affiliates and subject to the limitations set forth in Section 4(c), GWROP agrees to pay to Apollo or its designee an annual fee equal to the greater of $2 million and 2% of EBITDA for the immediately prior calendar year (the “Management Fee”). The Management Fee for each calendar year shall be payable on April 1st of that year, with the first such payment being made on April 1, 2013 and a pro rated fee will be paid in the twelfth year based on the number of days remaining in the Term. For the avoidance of doubt, no fee shall be payable with respect to calendar year 2012, but the fee with respect to calendar year 2013 will be based on EBITDA during calendar year 2012.

(b) Change of Control or Initial Public Offering. The parties acknowledge and agree that an objective of GWROP is to maximize value for its direct and indirect shareholders which may include consummating (or participating in the consummation of) a Change of Control or a Qualified IPO. The services provided to GWROP by Apollo or any of its Affiliates will help to facilitate the consummation of a Change of Control or Qualified IPO, should GWROP, GWRI or K-9 Holdings, Inc. (“Parent”) or any direct or indirect parent of Parent decide to pursue such a transaction. Following the provision of notice to Apollo by GWROP of GWROP’s, GWRI’s, Parent’s or any direct or indirect parent of Parent’s intent to enter into a Change of Control or Qualified IPO, Apollo may elect at any time in connection with or in anticipation of such Change of Control or Qualified IPO (or at any time thereafter) by the delivery of notice to GWROP (such notice, the “Notice” and the date on which such Notice is delivered to GWROP, the “Notice Date”) to receive, subject to the limitations set forth in Section 4(c), the Lump Sum Payment, in lieu of annual payments of the Management Fee, such amount to be paid on the date on which the Change of Control or Qualified IPO is consummated, or, if the Notice occurs subsequent to such date, as soon as practicable, but in no event later than 30 days subsequent to the Notice Date.

(c) Non-Payment. Notwithstanding anything in this Agreement to the contrary, neither GWROP nor GWRI has any obligation to pay any portion of the fees, expenses or other amounts payable to Apollo to the extent that (i) the Notes remain outstanding, (ii) aggregate payments under the Agreement would otherwise equal or exceed $5 million and (iii) such payments in excess of $5 million is determined by GWROP would be prohibited under Section 4.13 of the indenture governing the Notes (the “Affiliate Transaction Prohibition”). From and after the time when the Notes are no longer outstanding or the Affiliate Transaction Prohibition is determined by GWROP not to be applicable (the “Applicable Date”), any portion of fees, expenses or other amounts payable to Apollo (or its designees) under this Agreement arising on or after the Applicable Date which GWROP or GWRI is prohibited from paying to Apollo under any other agreement or debt instrument shall be deferred, shall accrue and shall be payable at the earliest time permitted under the applicable agreement or debt instrument, or upon the payment in full of all obligations under any applicable debt instrument. GWROP shall notify Apollo of any payment prohibition on each date on which GWROP would otherwise make a payment of fees under this Agreement.

(d) Non-Exclusive. Nothing in this Agreement (other than the limitations in Section 4(c)) shall have the effect of prohibiting Apollo or any of its Affiliates from receiving from GWROP or any of its subsidiaries or Affiliates any other fees, including, subject to the limitations in Section 4(c), any fee payable pursuant to Section 5.

(e) Definitions. As used in this Section 4 the following terms have the following meanings:

(2) The “Lump Sum Payment” shall be a single lump sum cash payment equal to the present value of all Management Fees payable under this Agreement through the end of the Term (using a discount rate equal to the yield to maturity on the Notice Date of the class of outstanding U.S. government bonds having a final maturity closest to the end of the Term).

(3) A “Qualified IPO” means a public offering and sale of equity securities of GWROP, GWRI, or Parent (or any successor entity) or any direct or indirect parent of Parent in any transaction or series of related transactions, pursuant to an effective registration statement (other than on Form S-4, S-8 or their equivalents) filed under the United States Securities Act of 1933, as amended which yield net proceeds to GWROP, GWRI, Parent or Apollo and its Affiliates in excess of $50 million or which results in least 10% of the total outstanding shares of common stock being sold to the public in a primary offering.

If GWROP shall determine that it is advisable for GWROP to hire a financial advisor, consultant, investment banker or any similar agent in connection with any merger, acquisition, disposition, recapitalization, issuance of securities, financing or any similar transaction, it shall notify Apollo of such determination. Promptly thereafter, upon the request of Apollo, the parties shall negotiate in good faith to agree upon appropriate services, compensation and indemnification for GWROP to hire Apollo or its Affiliates for such services. GWROP may not hire any person, other than Apollo or its Affiliates, for any services, unless (a) the parties are unable to agree after 30 days following receipt by Apollo of such notice, (b) such other person has a reputation that is at least equal to the reputation of Apollo in respect of such services, (c) ten business days shall have elapsed after GWROP provides a written notice to Apollo of its intention to hire such other person, which notice shall identify such other person and shall describe in reasonable detail the nature of the services to be provided, the compensation to be paid and the indemnification to be provided, (d) the compensation to be paid is not more than Apollo was willing to accept in the negotiations described above, and (e) the indemnification to be provided is not more favorable to GWROP than the indemnification that Apollo was willing to accept in the negotiations described above.
