            -------------------------------------------------------

       Business Editors - New York - (Business Wire - September 20, 2004)

     Intervest  Bancshares  Corporation  (NASDAQ:  IBCA)  (the  "Company") today
announced that it has sold trust preferred securities in the aggregate amount of
$15 million through FTN Financial Capital Markets, a division of First Tennessee
Bank  National  Association. The securities were sold to institutional investors
in  a private transaction, pursuant to an applicable exemption from registration
under  the  Securities  Act  of 1933. This represents the fourth trust preferred
transaction  that  the  Company  has  completed for an aggregate of $60 million.

     The  securities  mature  in  30  years and bear interest at a fixed rate of
6.20%  per  annum  for the first five years and thereafter at a floating rate of
2.40%  over  3  month  LIBOR.  The  securities can be redeemed by the Company at
anytime  after  five  years  or  earlier  under  certain  conditions, subject to
regulatory  approval.  The  Company  will  use the proceeds from the sale of the
securities  for working capital and investment in its wholly owned subsidiaries.

     The  principal  subsidiary of the Company is Intervest National Bank, which
is  a  nationally  chartered,  full-service  commercial  bank  that  has  its
headquarters  and full-service banking office in Rockefeller Center, in New York
City,  and  five full-service banking offices in Florida, four in Clearwater and
one  in  South  Pasadena.  At  June  30,  2004,  the  Bank  had  total assets of
$982,193,000  and  total  regulatory capital of $97,383,000. The Company expects
the investment of additional Tier 1 working capital into Intervest National Bank
will  give  the  Bank  the ability to grow deposits and potentially increase the
Bank's  future  earnings,  and  accordingly the future earnings per share of the
Company.

     Since  December  31,  1999, Intervest Bancshares Corporation's consolidated
assets  have  grown  from  $340,481,000  to  $1,119,266,000  at  June  30, 2004.
