I. PROPOSED MERGER OF THE DREYFUS CORPORATION
The Fund's adviser, The Dreyfus Corporation ("Dreyfus"), has entered
into an Agreement and Plan of Merger providing for the merger (the
"Merger") of Dreyfus with a subsidiary of Mellon Bank, N.A. ("Mellon").
Following the Merger, it is planned that Dreyfus will be a direct
subsidiary of Mellon. Closing of the Merger is subject to a number of
