Item 4 is hereby amended to add:

      The Applicants submit that Section 10(f) of the Public 
Utility Holding Company Act does not apply to the 
implementation filings which the applicants must make with 
the New York and Pennsylvania Departments of State after the 
Commission has approved this Application/Declaration.

      When and if the Commission approves this 
Application/Declaration, National and Penn-York would 
complete the pro-forma Departments of State filings attached 
to this Application/Declaration as Exhibit D-2, filling in as 
the effective date the next end-of-quarter date which arises 
after receipt of the Commission's approval.  The Departments 
of State will perform the essentially ministerial duties of 
verifying that the documents are in order and that Penn-York 
is current on its New York taxes.  Upon the acceptance of 
those filings (or upon a subsequent date set out in the 
filings), the merger becomes effective.  See New York 
Business Corporation Law, Section 907(g), and Pennsylvania 
Business Corporation Law, Section 1928.  The Commission 
should not require (or even allow) National and Penn-York to 
make the Departments of State filings before the Commission 
has ordered that this merger may proceed.
