  Let k be an algebraically closed field of characteristic p=2. Let G=F_4 be
simply connected over k and let \sigma:G\to G be an endomorphism such that the
fixed point set G(\sigma) is a Ree group. We show, using the methods of
Bendel--Nakano--Pillen, that self-extensions of simple kG(\sigma)-modules
vanish generically and that for all but the first few Ree groups of type F_4,
the 1-cohomology for G(\sigma) with coefficients in simple kG-modules can be
identified with the 1-cohomology for G with coefficients in (possibly
different) simple G-modules.
