We explore the global structures of a time-dependent, spherically symmetric solution derived by compactifying intersecting M-branes. The metric we study is an exact solution of Einstein-Maxwell-dilaton system, in which four Abelian gauge fields couple to the dilation with different coupling constants. We find that the spacetime is two-parameter family and describes a charged black hole which asymptotically tends to the Friedmann-Lemaître-Robertson-Walker (FLRW) universe filled by a stiff matter.
