                                (Exhibit No. 25)


All powers of attorney required to be filed are substantially identical in all
material respects.  Therefore, in accordance with SEC Regulation 229.601(a)
Instruction 2, only the foregoing copy is being included except, however, that
the manually signed copy filed with the Securities and Exchange Commission
includes a complete set of powers of attorney.

All powers of attorney differ only from the form of the foregoing in that they
are executed by the following parties in the capacities indicated on or about
February 22, 1995, and the power by E. Allen Deaver appoints George A. Lorch
only as his agent:

     William J. Wimer    Senior Vice-President, Finance, and
                           Treasurer
                           (Principal Financial Officer)
     Bruce A. Leech, Jr. Controller
                           (Principal Accounting Officer)
