Abstract
For every polynomial $F$ in two complex variables we define the Łojasiewicz exponents ${\it\$}_{p,t}(F)$ measuring the growth of the gradient $\nabla F$ on the branches centered at points $p$ at infinity such that $F$ approaches $t$ along $\gamma$. We calculate the exponents ${\it\$}_{p,t}(F)$ in terms of the local invariants of singularities of the pencil of projective curves associated with $F$.
