Extending a result of Manivel, we prove the following: THEOREM. Suppose ∑ibi ≥ ∑jaj+n and ∑ibi [n+didi −1] ≥ ∑jaj [n+ljlj −1] +n. Then the kernel E(d) of the general morphism: ⊕vi=1 (Bi ⊗ Opn (di))→⊕vj=1(Aj ⊗ Opn (lj)) (l1 … >ls > d1 …>dv) is a globally generated vector bundle, except for at most finitely many sets { bi, aj}.
