Iowa Code Title XII. Business Entities [Chs. 486-504C] § 498.19. Power to compel sales and purchases--liquidated damages

1. The association may require members to sell all or a stipulated part of their specifically enumerated products exclusively through the association or to buy specifically enumerated supplies exclusively through the association, but in such case, a reasonable period during each year shall be specified during which any member, by giving notice in prescribed form, may be released from such obligation thereafter. Where it is desired to enter into the exclusive arrangement provided in this section, the association shall execute a contract with each such member setting forth what goods or wares are to be handled and upon what terms. In order to protect itself in the necessary outlay, which it may make for the maintenance of its services, the association may stipulate that some regular charge shall be paid by the member for each unit of goods covered by such contract whether actually handled by the association or not, and in order to reimburse the association for any loss or damage which it or its members may sustain through the member's failure to deliver the member's products to or to procure the member's supplies from the association.

2. In case it is difficult or impracticable to determine the actual amount of damage suffered by the association or its members through such failure to comply with the terms of such a contract, the association and the member may agree upon a sum to be paid as liquidated damages for the breach of the member's contract, said amount to be stated in the contract.
