license to use the "Buffalo Wild Wings" Marks and System, and you undertake the obligation to operate a Buffalo Wild Wings restaurant facility featuring the Menu Items and providing sit-down, carry-out and other restaurant services ("Franchised 1 Restaurant"), and to use the Marks solely in connection with the System, as it is currently established, and as it may be changed, improved and further developed from time to time, at one (1) location only, such location to be: 1) ____________________________________________________________________________ ___________________________________________________________________________, or 2) at a location to be designated, as provided in Paragraph III within the area described on EXHIBIT B. When a location has been designated and approved by you and us, it will become part of Paragraph I.A.1., as if originally incorporated in that Paragraph. You shall not relocate your Franchised Restaurant without our prior written approval. B. You receive a Designated Area within which we and our affiliates shall not operate or grant to anyone else a franchise to operate a Buffalo Wild Wings or bw-3 Restaurant so long as this Agreement is in force and effect. The Designated Area is described in writing and on a map attached to the Agreement as EXHIBIT B and is made a part of the Agreement. You do not have any right to sublicense or subfranchise others within or outside of the Designated Area and do not have the right to operate more than one (1) Franchised Restaurant within the Designated Area. C. You acknowledge and agree that we have the right, in our sole discretion, to grant other franchises outside of the Designated Area as we deem appropriate. Although we will not operate a Buffalo Wild Wings or bw-3 business within the Designated Area, we reserve the right, both within and outside of the Designated Area, to offer and sell at special events (at our option, if you elect not to participate in such events) or at wholesale, through channels of distribution distinct from those of a Franchised Restaurant, products and services which comprise, or may in the future comprise a part of the System, which products may be resold at retail to the general public by such entities. Further, you acknowledge that certain locations within the Designated Area are by their nature unique and separate in character from sites generally developed as Franchised Restaurants. As a result, you agree that the following locations ("Special Sites") are excluded from the Designated Area and we shall have the right to develop (by direct ownership or franchising) such locations: 1) public transportation facilities, including airports, train stations and bus stations; 2) military bases; 3) sports facilities, including race tracks; and 4) amusement and/or theme parks. D. We and our affiliated companies shall not engage in catering and delivery services and activities in the Designated Area. You shall not engage in catering and delivery services and activities outside of the Designated Area. We shall have no obligation to enforce similar covenants against any other System franchisee. Other System franchisees shall be deemed third party beneficiaries of such. You shall not offer for sale any Menu Items or Proprietary Products by means of Internet/World Wide Web programming or advertising. We reserve the right to market and sell Menu Items and Trade Secret Food Products on the Internet/World Wide Web. E. You pay us a nonrefundable Initial Franchise Fee of ________________ _______________________ Dollars ($________) which is payable in full on the date of this Agreement. The Initial Franchise Fee has been fully earned upon receipt and is nonrefundable in consideration of the expenses incurred by us in granting this franchise and for the lost or deferred opportunity to franchise others. F. You acknowledge that because complete and detailed uniformity under many varying conditions may not be possible or practical, we specifically reserve the right, at our sole discretion, to vary standards for any System franchisee based upon the peculiarities of the particular site or circumstance, density of population, business potential, population of trade area, existing business practices or any other condition which we deem to be of importance to the successful operation of such franchisee's business. You shall not be entitled to require us to grant to you a like or similar variation. G. In consideration of our agreement not to grant another franchise in the area described in Paragraph I.C., you at all times shall use your best efforts to promote and increase the sales and service of Menu 2 Items and to effect the widest and best possible distribution throughout the Designated Area,
