             COMPLETES THE SALE OF $15 MILLION OF CAPITAL SECURITIES
             -------------------------------------------------------

       Business Editors - New York - (Business Wire - September 17, 2003)

     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 issued in the offering 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  second  trust  preferred  transaction  that  the  Company  has  completed.

     The  securities  bear  interest  at a fixed rate of 6.75% per annum for the
first  five years and thereafter at a floating rate based on LIBOR and mature in
30  years.  The  securities can be redeemed by the Company at anytime after five
years.  The  Company will use the proceeds 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  a  total  of five full-service banking offices in Florida - of which
four  are  in  Clearwater  and  one is in South Pasadena. The addition of Tier 1
capital  to  Intervest  National  Bank  will give the Bank the potential to grow
deposits  and  potentially  increase the Bank's future earnings, and accordingly
the  future  earnings  per  share  of  the  Company.

     Since  1996,  Intervest  Bancshares  Corporation's consolidated assets have
grown at an annualized rate of approximately 35%, to $750,000,000 as of June 30,
2003,  and  book  value per common share has increased 79% to $12.23 in the same
time  frame.

     This  press  release  shall  not  constitute  an  offer  to  sell  or  the
solicitation  of an offer to buy nor shall there be any sale of these securities
in  any  state in which such offer, solicitation or sale would be unlawful prior
to  registration  or  qualification  under the securities law of any such state.
