The Contract Manufacturing Agreement covers (or should cover) many aspects of the mission including quality standards, payment terms, over-run allowances, conflict resolutions, formulation development, IP/brand exclusivity, path to ownership. etc, etc. I’ve seen some that were 20 -plus pages long. The one I drafted years ago was less than 8 pages. If I can dig it up I can send it to you but don’t hold your breath waiting. Full disclosure: I was in the contract manufacturing biz for 35 years so my agreement is from the “other side”.
