this Post-Effective Amendment No. 1 to deregister an aggregate of 26,000 shares
of its common stock, no par value, previously registered under the Securities
Act of 1933 pursuant to the registration statement.

Financial Company pursuant to exemptions to the Securities Act.  Following the
merger, the shares were registered pursuant to the registration statement in
order to facilitate the resale of the shares by any selling shareholders.  Fifth

effectiveness of this registration statement until the earlier to occur of (a)
one year after the effective time of the merger, or (b) the first date as of

statement.

     As of June 28, 2001, an aggregate of 26,000 shares registered under this
registration statement (as adjusted) remain unsold by the selling shareholders.
Therefore, in accordance with the undertakings mentioned above, Fifth Third
hereby deregisters the remaining 26,000 shares of Fifth Third common stock
previously registered pursuant to the registration statement.
