           REPORTS 2006 FIRST QUARTER EARNINGS DOUBLE TO $6.4 MILLION
           ----------------------------------------------------------

         Business Editors - New York - (Business Wire - April 12, 2006)

     Intervest  Bancshares  Corporation  (NASDAQ:  IBCA)  (the  "Company") today
reported  that  its  consolidated  net  earnings  for  the first quarter of 2006
increased by $3.2 million, or 100%, to $6.4 million, or $0.77 per diluted share,
from $3.2 million, or $0.48 per diluted share, in the first quarter of 2005. The
earnings  per share calculation for the 2006 period included a greater number of
outstanding  shares  resulting  primarily  from a public offering of 1.4 million
shares  of  Class  A  common  stock  in  the  third  quarter  of  2005.

     The  Company's  efficiency  ratio,  which  is  a  measure of its ability to
control  expenses as a percentage of its revenues, continues to be favorable and
improved  to  19% in the first quarter of 2006, from 26% in the first quarter of
2005.  The Company's return on average assets and equity also increased to 1.47%
and  18.55%,  respectively,  in the 2006 first quarter, from 0.94% and 14.25% in
the 2005 first quarter. The Company's book value per common share rose to $18.22
at  March  31,  2006,  from  $17.41  at  December  31,  2005.

     The  increase  in 2006 first quarter earnings of $3.2 million reflected the
continued  growth  in the Company's lending activities and an improvement in its
net  interest  margin.  Net  interest and dividend income, the Company's primary
source  of  revenues,  grew  by  51%  or $4.2 million, reflecting a $321 million
increase  in  average  loans  outstanding and a higher net interest margin. In a
steadily  rising  interest  rate  environment, the Company's net interest margin
improved  to  2.92%  in  the  2006  first  quarter, from 2.47% in the 2005 first
quarter,  as  the  yield on the Company's interest-earning assets increased at a
faster pace than its cost of funds. Noninterest income increased by $1.2 million
primarily  due  to  a  higher  level  of income from loan prepayments, while the
provision  for loan losses decreased by $0.7 million primarily due to a decrease
in  the  rate  of  net  loan growth over the prior year period. The increases in
income  and  the lower provision for loan losses were partially offset by a $2.5
million  increase  in  income tax expense due to higher pretax income and a $0.4
million  increase  in  noninterest  expenses  primarily  due to increases in the
Company's  staff  and its other operating expenses associated with the Company's
growth.  The Company had 76 employees at March 31, 2006, compared to 67 at March
31, 2005. The Company's effective income tax rate was approximately 44% for both
reporting  periods.

     Total  consolidated  assets  at  March  31,  2006  increased by 5% to $1.79
billion  from  $1.71  billion  at  December 31, 2005. The increase reflected the
growth  in  the  Company's  loan  portfolio  and  a  higher  level  of  security
investments,  partially  offset  by  a decrease in other short-term investments.

     Total consolidated loans, net of unearned fees, at March 31, 2006 increased
by 2% to $1.40 billion from $1.37 billion at December 31, 2005. The increase was
due to new mortgage loan originations secured by commercial and multifamily real
estate  exceeding  principal  repayments.  New  loan  originations  totaled $144
million  for  the  first  quarter of 2006, compared to $151 million for the same
period  of  2005.



     Total  consolidated security investments at March 31, 2006 increased 30% to
$334.3  million  from  $256.7  million  at  December  31,  2005.  The investment
portfolio  at  March 31, 2006, all of which was held by Intervest National Bank,
had  a  weighted-average  remaining  maturity of 1.4 years and a yield of 3.88%,
compared  to  1.1  years  and  a  yield of 3.26% at December 31, 2005. Intervest
National  Bank  invests in short-term U.S. government agency debt obligations to
emphasize  liquidity  and  currently  targets  its  loan-to-deposit  ratio  at
approximately  85%.

     Total  consolidated cash and other short-term investments at March 31, 2006
decreased  by  51% to $27.8 million from $56.7 million at December 31, 2005. The
decrease  reflected  the  investment  of  funds  into  loans  and  securities.

     Total  consolidated  deposits  at  March  31, 2006 increased by 4% to $1.43
billion  from  $1.38  billion  at  December  31, 2005, reflecting an increase in
certificate  of  deposit accounts of $34 million and a net increase in checking,
savings  and  money  market  accounts  totaling  $21  million.

     Total consolidated borrowed funds and related interest payable at March 31,
2006  increased  by  15%  to  $178.5 million from $155.7 million at December 31,
2005.  The  increase  was due to $23.5 million of short-term borrowings from the
Federal  Home  Loan  Bank  of  New  York  by  Intervest  National  Bank.

     Total  consolidated  stockholders' equity at March 31, 2006 increased by 5%
to  $142.8  million  from  $136.2  million  at  December  31, 2005. The increase
reflected  net  earnings of $6.4 million and $0.2 million from the conversion of
convertible  debentures  into  common  stock.

(1)  Represents  net  earnings  plus  interest expense on dilutive convertible debentures, net of taxes, that would not
     occur  if  the  convertible  debentures  were  assumed  to be converted for purposes of computing diluted earnings
     per share.

(2)  Diluted EPS includes shares that would be outstanding if dilutive common stock warrants and convertible debentures
     Were  assumed  to  be  exercised/converted  during  the  period.  All outstanding warrants were considered for the
     EPS computations.

     Convertible debentures (principal and accrued interest) outstanding at March 31, 2006 and 2005 totaling $3,306,000
     and $4,798,000, respectively, were convertible into common stock at a price of $16.00 per share in 2006 and $14.00
     per  share in 2005. Assumed conversion results in additional common shares (based on average balances outstanding)
     of approximately 212,000 in the 2006 EPS computation and 343,000 in the 2005 EPS computation.

(3)  Returns for the quarter have been annualized.
