We have an advisor who has worked with late stage companies. He has signed the agreement and asked us if there will be a stock agreement etc. that will show strike price etc. Any advice on how you're handling the follow-up to the agreement with advisors?

When you grant someone options - they come with a strike price, vesting schedule (if any), and formal Option Plan that has been approved by the board.

Unless you are giving them an agreement with the disclosure - you will give them options in the future (pending board approval) - once you have an Option Plan in place.
