N.D. Cent. Code § 41-02-23

(3) If an estimate of output or requirements is included in the agreement, no quantity unreasonably disproportionate to it may be tendered or demanded. Any minimum or maximum set by the agreement shows a clear limit on the intended elasticity. In similar fashion, the agreed estimate is to be regarded as a center around which the parties intend the variation to occur.

(4) When an enterprise is sold, the question may arise whether the buyer is bound by an existing output or requirements contract. That question is outside the scope of this Article, and is to be determined on other principles of law. Assuming that the contract continues, the output or requirements in the hands of the new owner continue to be measured by the actual good faith output or requirements under the normal operation of the enterprise prior to sale. The sale itself is not grounds for sudden expansion or decrease.

(5) Subsection (2), on exclusive dealing, makes explicit the commercial rule embodied in this Act under which the parties to such contracts are held to have impliedly, even when not expressly, bound themselves to use reasonable diligence as well as good faith in their performance of the contract. Under such contracts the exclusive agent is required, although no express commitment has been made, to use reasonable effort and due diligence in the expansion of the market or the promotion of the product, as the case may be. The principal is expected under such a contract to refrain from supplying any other dealer or agent within the exclusive territory. An exclusive dealing agreement brings into play all of the good faith aspects of the output and requirement problems of subsection (1). It also raises questions of insecurity and right to adequate assurance under this Article.
