1. In addition to any other information or documents required by law, an applicant for a license which grants alone or with other privileges the privilege of selling intoxicating liquor containing not in excess of five percent of alcohol by weight by a wholesaler to a person duly licensed to sell such malt liquor at retail shall submit to the supervisor of liquor control a statement under oath designating clearly the geographical area within which the applicant has been authorized by the brewer to sell such malt liquor, the brand or brands he proposes to sell, and the brewer or brewers who manufacture the brands, and affirming that the applicant will maintain a warehouse and delivery facilities within the designated geographical area. Each such wholesaler applicant shall enter into a written agreement with the brewer of the brand or brands which the applicant proposes to sell, which agreement must specifically designate a geographic area within which such wholesaler applicant is authorized to sell such brand or brands. A copy of such written agreement shall be filed with the supervisor of liquor control as a part of such application. It shall be unlawful for any such wholesaler applicant, who is granted a license hereunder, to sell any brand or brands of malt liquor in the state of Missouri except in the designated geographic area described in said agreement. Provided, however, that when such an applicant is prevented from servicing the designated geographic area due to fire, flood, or other causes beyond his reasonable control, another licensed wholesaler not within the designated geographic area may sell the specified brands of malt liquor in that designated geographic area, if the applicant wholesaler who is prevented from servicing the area consents thereto and approval is obtained from the applicable brewer and the supervisor of liquor control.

2. A specified geographic area designation in any agreement required by this section shall be changed only upon a written agreement between the wholesaler and the brewer, and shall be filed pursuant to this section and the supervisor shall require the brewer and wholesaler to verify that the level of service within the designated geographic area will not be affected by such change.

3. No provision of any written agreement required by this section shall expressly or by implication or in its operation establish or maintain the resale price of any brand or brands of beer by the licensed wholesaler.

4. The provisions of section 311.720 shall not apply to this section.
