Henkel Corp. v. Innovative Brands Holdings LLC, C.A. 3663-VCN (Del. Ch. Aug. 26, 2008)

Merger agreements frequently permit a merger to be terminated in the event of a materially adverse change to the business of the company to be acquired. When the right to invoke such a MAC clause is not set by the agreement, this decision holds that it must be invoked within a reasonable time. What is reasonable depends on the circumstances.
