  We introduce a coupled pair of evolution equations for the unintegrated gluon
distribution and the sea quark distribution which incorporate both the resummed
leading $\ln (1/x)$ BFKL contributions and the resummed leading $\ln (Q^2)$
DGLAP contributions. We solve these unified equations in the perturbative QCD
domain. With only two physically motivated parameters we obtain an excellent
description of the HERA $F_2$ data.
