If they give him 10% out of an options pool of 20%, he just cut the options pool in half for future employees. This will make it harder to attract future staff, who will be needed to grow the company enough to make the equity worthwhile. Isn't taking too much post-financing risky too?
Not sure why somebody downvoted you; that is definitely correct. VCs have some very clear notions about the correct size for employee equity pools. They insist on creating one as part of the initial funding, so it doesn't come out of their share. For similar reasons, they will resist increasing it later.
