The Pactix definition of "knowledge" is copied verbatim from UCC § 1-202(B). It does not include any duty of inquiry.

For the avoidance of doubt, other subparagraphs of that UCC section were not incorporated into the "knowledge" definition; some of those other subparagraphs define “notice” and specify default rules for when an organization has knowledge or notice of a fact, which might conflict with the notice provisions of the contract.
