Exponentiating the hypergeometric series
0_F_L(1,1,...,1;z), L = 0,1,2,..., furnishes a recursion relation for the members of certain integer sequences
b_L(n), n = 0,1,2,.... For L >= 0, the b_L(n)'s are generalizations of the conventional Bell numbers, b_0(n). The corresponding associated Stirling numbers of the second kind are also investigated. For L = 1 one can give a combinatorial interpretation of the numbers b_1(n) and of some Stirling numbers associated with them. We also consider the L>1 analogues of Bell numbers for restricted partitions.
