  Magnetic Eternally Collapsing Objects (MECO) have been proposed as the
central engines of galactic black hole candidates (GBHC) and supermassive
active galactic nuclei (AGN). Previous work has shown that their luminosities
and spectral and timing characteristics are in good agreement with
observations. These features and the formation of jets are generated primarily
by the interactions of accretion disks with an intrinsically magnetic central
MECO. The interaction of accretion disks with the anchored magnetic fields of
the central objects permits a unified description of properties for GBHC, AGN,
neutron stars in low mass x-ray binaries and dwarf novae systems. The
previously published MECO models have been based on a quasistatic Schwarzschild
metric of General Relativity; however, the only essential feature of this
metric is its ability to produce extreme gravitational redshifts. For reasons
discussed in this article, an alternative development based on a quasistatic
exponential metric is considered here.
