provided, however, that nothing contained herein shall require any manufacturer, winegrower, farmer-brewer or wholesaler to file a schedule of minimum consumer resale prices for any brand of alcoholic beverages offered for sale or sold (1) to a retailer under a brand which is owned exclusively by such retailer and sold within the commonwealth exclusively by such retailer; (2) to a church, synagogue or religious organization under a brand which is owned exclusively by such manufacturer, farmer-brewer, winegrower, or wholesaler, if authorized to sell wine or malt beverages to such persons and such wine or malt beverages are sold exclusively to such persons; (3) to on-premises retailers under a brand which is owned exclusively by such manufacturer, winegrower, farmer-brewer or wholesaler and is sold by such manufacturer, winegrower, farmer-brewer or wholesaler exclusively to such retailers for consumption on the premises.
No such filing, however, shall take effect unless within thirty days thereafter the commission shall approve such prices as not being excessive, inadequate, or unfairly discriminatory; provided, however, that such approval shall not be deemed a rule or regulation within the meaning of section twenty-four or section seventy-one, nor shall such approval be subject to the provisions of chapter thirty A.
(4) to permit the sale by a retailer of a brand of alcoholic beverages for which a schedule of minimum consumer resale prices has not been and cannot be filed, whenever necessary to avoid practical difficulties or unnecessary hardships to any licensee affected by this section or because of acts or circumstances beyond the control of such licensee, and under such terms and conditions as are necessary to carry out the purposes of this section.
All schedules filed pursuant to this section shall be subject to public inspection from the time that they are required to be made available for inspection by licensees, and shall not be considered confidential.

Each manufacturer, winegrower, farmer-brewer and wholesaler shall retain in his licensed premises for inspection by licensees a copy of his filed schedules as then in effect.
