In this paper, we investigate exponentially biharmonic maps $u:(M,g)\rightarrow(N,h)$ from a Riemannian manifold into a Riemannian manifold with non-positive sectional curvature. We obtain that if \begin{align*} &\int_Me^{\frac{p|\tau(u)|^2}{2}}|\tau(u)|^{p}dv_g<\infty~(p\geq2),~\int_M|\tau(u)|^{2}dv_g<\infty\text{ and}\\ &\int_M|du|^{2}dv_g<\infty, \end{align*} then $u$ is harmonic. When $u$ is an isometric immersion, we get that if $\int_Me^{\frac{pm^2|H|^2}{2}}|H|^{q}dv_g<\infty$ for $2\leq p<\infty$ and $0 Keywords: exponentially biharmonic maps, exponentially biharmoinc submanifolds MSC numbers: Primary 58E20, 53C21
