effected by means of the merger of THB with and into PennFirst (the
"Merger").  Upon consummation of the Merger, each share of common stock,
$.01 par value per share, of THB ("THB  Common  Stock") outstanding
immediately prior thereto was converted into the right to receive, at the
election of the holder thereof, $21.15 in cash or 1.52 shares of common
stock, $.01 par value per share, of PennFirst ("PennFirst Common Stock")
(or under certain circumstances, a combination of cash and shares of
PennFirst Common Stock), subject to the condition that the aggregate amount
of cash consideration paid to THB shareholders constitute 40% of the total
consideration paid for the THB Common Stock by PennFirst.

     (b)  The physical property acquired in connection with the acquisition
of THB was used by THB in the conduct of its business as a thrift holding
company.  PennFirst intends to continue such use.
