The bylaws or the marketing contract may fix, as liquidated damages, specific sums to be paid by the member or stockholder to the association upon the breach by him of any provision of the marketing contract regarding the sale or delivery or withholding of products, and may further provide that the member will pay all costs, premiums for bonds, expenses and fees, in case the association shall prevail in any action brought by it upon the contract; and any such provisions shall be valid and enforceable in the courts of this state; and such clauses providing for liquidated damages shall be enforceable as such and shall not be regarded as penalties.

In the event of any such breach or threatened breach of such marketing contract by a member, the association shall be entitled to an injunction to prevent the further breach of the contract and to a decree of specific performance thereof. Pending the adjudication of such an action and upon filing a verified complaint showing the breach or threatened breach, and upon filing a sufficient bond, the association may be entitled to a temporary restraining order and preliminary injunction against the member.

In any action upon such marketing agreement, it shall be presumed as between the parties that the landowner, landlord or lessor claiming therein so to be is able to control the delivery of products produced on his land by tenants or others, whose tenancy or possession or work on such land or the terms of whose tenancy or possession or labor thereon were created or changed after execution by the landowner, landlord or lessor of such marketing agreement; and in such actions the foregoing remedies for nondelivery or breach shall lie and be enforceable against such landowner, landlord or lessor.
