An associative algebra of holomorphic differential forms is constructed ass
ociated with pure N = 2 super-Yang-Mills theory for the Lie algebra F-4. Ex
istence and associativity of this algebra, combined with the general argume
nts in the work of Marshakov, Mironov and Morozov, proves that the prepoten
tial of this theory satisfies the generalized WDVV (Witten-Dijkgraaf-Verlin
de-Verlinde) system. (C) 2001 Published by Elsevier Science B.V.
