...no those are "Financial Terms"..., can still be open after "the Science" DD is satisfied.
Negotiation and DD Process:
1. Science/Technology DD: Prove the Science...otherwise 2-4 is meaningless
2. Negotiate the Parameter of Rights to be Acquired: what you want to buy (in whole or in part) and where...buy or license outright or in part, negotiate territorial rights (if not bought outright).
3. Negotiate the Financial Terms: the Price, Payments Terms and Royalties (if any)
4. Legal DD...document the rights of Target and what they have the rights, title and interest in. What they own or their derivative right to sell or license... Acquired/Seller/Licensor has to prove it's chain of title to those rights and patents etc.
