We study Lyapunov, central and auxiliary exponents of linear Ito stochastic equations. We show that the central exponents are nonrandom like Lyapunov exponents, the nonrandomness of which was proved in [8]. We prove that under a nondegeneracy condition the central exponents $\Theta_k$ of a linear Ito stochastic differential equation coincide with its auxiliary exponents $\gamma_k$, and, moreover, all the first exponents coincide: $\Theta_1 = \lambda_1 = \Omega_1 = \gamma_1$.
