Flex Option Contract vs Option to Purchase Contract

[Debra S.]

Hi, not sure if I'm in the right section, but I've been reading about the "option to purchase contract" and recently heard about the "flex option contract".   Are these the same thing?  The language looks similar, but some versions of the contract use the words optionor/optionee and others I've seen use the words seller/buyer.

So my questions are: Are the flex option contract and the option to purchase contract the same?

If they are the same, which is the correct language to use?  optionor/optionee or seller/buyer?

Thanks
