Abstract: 
 In this paper, we study the exponential stability of linear
 non-autonomous systems with multiple delays. Using
 Lyapunov-like function, we find sufficient conditions for the
 exponential stability in terms of the solution of a
 Riccati differential equation. Our results are illustrated
 with numerical examples.
