815 ILCS 715/3
Whenever any retailer enters into a written or oral agreement with a wholesaler, manufacturer or distributor wherein the retailer agrees to maintain an inventory and the contract is terminated by wholesaler, manufacturer, distributor, or retailer, then the retailer may require the repurchase of the inventory as provided for in this Act. If the retailer has any outstanding debts to the wholesaler, manufacturer or distributor then the repurchase amount may be credited to the retailer's account.
Any such agreement shall either expressly or by operation of law have as part of its terms a security agreement whereby the wholesaler, manufacturer or distributor agrees to and does grant a security interest to the retailer in the repurchased inventory to secure the payment of the repurchase amount to the retailer. The perfection, priority and other matters relating to such security interest shall be governed by Article 9 of the "Uniform Commercial Code".
