Rationally Isotropic Exceptional Projective
Homogeneous Varieties Are Locally Isotropic

Assume that $R$ is a regular local ring that contains an infinite field
and whose field of fractions $K$ has charactertistic $\ne 2$. Let $X$
be an exceptional projective homogeneous scheme over $R$. We prove that
in most cases the condition $X(K)\neq\emptyset$ implies $X(R)\neq\emptyset$.
