The behavior of solutions of a class of large-scale systems with the bounded coefficients of the form [1] has been studied. The function

, whose coefficient

is bounded for all

, gives the conditions on the Lyapunov function such that the system (1) is either asymptotically stable or unstable. Since the function of the form

is not positive definite in the Lyapunov sense, a Lyapunov function of the form

where

is bounded is constructed which is positive definite in the Lyapunov sense. A systematic procedure for the construction of such a function is given. The approach is quite general. The method is inspired from the papers of Grujic and Siljak [1], Siljak [2], [3], Weissenberger [4], Bailey [5], and Michel et al. [7], [8].
