        Business Editors - New York - (Business Wire - October 17, 2006)

     Intervest  Bancshares  Corporation  (NASDAQ-GS: IBCA) (the "Company") today
reported  that  its  consolidated  net  earnings  for  the third quarter of 2006
increased  by  $0.3 million, or 7%, to $4.9 million, or $0.59 per diluted share,
from $4.6 million, or $0.61 per diluted share, in the third quarter of 2005. For
the  first  nine  months  of  2006,  consolidated net earnings increased by $5.4
million, or 44%, to $17.7 million or $2.13 per diluted share, from $12.3 million
or  $1.76  per  diluted share in the first nine months of 2005. The earnings per
share  calculations  for  the  2006 periods included a greater number of average
shares  outstanding  resulting  primarily  from a public offering of 1.4 million
shares  of  Class  A common stock during the third quarter of 2005. Earnings for
the 2006 periods were reduced by a one-time charge of $1.5 million ($0.9 million
after  tax) resulting from the Company's contractual obligation to provide death
benefit  payments  to  the  spouse of the Company's former Chairman and founder,
Jerome  Dansker,  who passed away in August of this year. This charge represents
the  estimated  net  present value of the future contractual payments that total
$1.9  million.

     The  $0.3  million  increase  in  2006 third quarter earnings over the same
period  of  2005 was due to a $1.9 million increase in net interest and dividend
income  and  a $0.9 million decrease in the provision for loan losses, partially
offset  by  a  $1.6  million  increase  in  noninterest expenses, a $0.6 million
decrease  in noninterest income and a $0.3 million increase in the provision for
income  taxes.  The  increase  in net interest and dividend income reflected the
continued  growth  in  the  Company's  lending  activities.  Total average loans
outstanding  grew  by  $240  million  while  the  Company's  net interest margin
decreased  slightly  to  2.71%  from  2.74%, despite a higher cost of funds. The
provision  for  loan losses was lower primarily due to a decrease in the rate of
net  loan  growth  over the prior year period, while the increase in noninterest
expenses  was nearly all due to the one-time charge of $1.5 million noted above.
Noninterest  income  decreased  due  to  a  lower  level  of  income  from  loan
prepayments, while the provision for income taxes increased due to higher pretax
income.  The  Company  had 75 employees at September 30, 2006, compared to 68 at
September  30, 2005, and its effective income tax rate was approximately 44% for
both  periods.

     The  Company's  efficiency  ratio,  which  is  a  measure of its ability to
control  expenses as a percentage of its revenues, continued to be favorable and
was  20%  (excluding the one-time charge) in the third quarter of 2006, compared
to  21% in the third quarter of 2005. The Company's return on average assets and
equity  was  1.05% and 12.90%, respectively, in the 2006 third quarter, compared
to  1.17% and 16.32% in the 2005 third quarter. Book value per common share rose
to  $19.66  at  September  30,  2006,  from  $17.41  at  December  31,  2005.

     Earnings  for  the first nine months of 2006 increased by $5.4 million over
the  same  period  of  2005  due to a $10.0 million increase in net interest and
dividend  income, a $1.4 million decrease in the provision for loan losses and a
$0.2  million  increase in noninterest income. These items were partially offset
by  a  $2.0 million increase in noninterest expenses and a $4.2 million increase
in  the  provision  for  income taxes. The increase in net interest and dividend
income  was  due  to  a $285 million increase in average loans outstanding and a
higher  net  interest margin of 2.85% compared to 2.61%. The higher margin was a
function  of  the  Company's  yield  on  interest-earning assets increasing at a
faster  pace than its cost of funds as well as an increase of $51 million in net
interest-earning  assets  resulting  largely from $26.3 million of proceeds from
the  issuance  of  common stock and increased retained earnings. The increase in
noninterest  expenses  reflected  the $1.5 million charge noted above as well as
increases  in professional fees and other operating expenses associated with the
Company's  growth in total assets. The increase in noninterest income was due to
a  higher level of banking fee income and fees earned from loan commitments that
expired  unfunded,  partially  offset  by  a  lower  lever  of  income from loan
prepayments.  The  reasons  for the changes in the provision for loan losses and
income  taxes  were  the  same  as  those  for  the  quarterly  period.



     Total  consolidated  assets at September 30, 2006 increased by 15% to $1.97
billion  from  $1.71  billion  at  December 31, 2005. The increase reflected the
growth  in  the  Company's  loan  portfolio  as  well  as  increases in security
investments  and  other  short-term  investments.

     Total  consolidated  loans,  net  of  unearned  fees, at September 30, 2006
increased  by  9% to $1.49  billion from $1.37 billion at December 31, 2005. The
increase  was due to new originations secured by commercial and multifamily real
estate  exceeding principal repayments. New originations totaled $147 million in
the  third  quarter  of  2006 and $437 million in the first nine months of 2006,
compared to $221 million and $545 million, respectively, for the same periods of
2005.  Loans on nonaccrual status amounted to $7.7 million and were comprised of
three  loans  at September 30, 2006, compared to two loans totaling $0.7 million
at  December  31, 2005. In September 2006, the two loans on nonaccrual status at
December  31,  2005  were  repaid.  At  September 30, 2006, there were six loans
totaling  $19.6  million  ninety days past due and still accruing interest since
they  were  deemed  to be well secured and in the process of collection. Five of
the  loans  ($17.2  million)  have  matured  and  the borrowers continue to make
monthly payments of interest and principal. It is anticipated that all six loans
will  be  repaid  in  full  or  refinanced  in  the  near  term.

     Total consolidated security investments at September 30, 2006 increased 35%
to  $346.6  million  from  $256.7  million  at December 31, 2005. The investment
portfolio  at  September  30,  2006, all of which was held by Intervest National
Bank,  had  a  weighted-average  remaining  maturity of 1.5 years and a yield of
4.53%,  compared  to  1.1  years  and  a  yield  of  3.26% at December 31, 2005.
Intervest National Bank continues to invest 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 September 30,
2006 increased by 82% to $103.0 million from $56.7 million at December 31, 2005.
The  increase  reflected  the  temporary  investment  of  deposit inflows during
September  2006.  A  portion of these funds is expected to fund new loans and to
retire  prior  to  their  stated  maturity certain debentures outstanding in the
fourth  quarter  of  2006.

      Total  consolidated  deposits  at  September  30, 2006 increased by 16% to
$1.60 billion from $1.38 billion at December 31, 2005, reflecting an increase in
certificate  of  deposit  accounts  of  $228.6 million partially offset by a net
decrease  in  checking, savings and money market accounts totaling $2.8 million.

     Total consolidated borrowed funds and related interest payable at September
30,  2006 increased by 12% to $174.1 million from $155.7 million at December 31,
2005.  The  increase  was  due to the previously announced sale on September 21,
2006  of $10.0 million of additional trust preferred securities as well as a $10
million  net increase in the outstanding debentures of the Company's subsidiary,
Intervest Mortgage Corporation. The Company intends to use the proceeds from the
sale  of  the  trust preferred securities, together with $5 million of available
cash,  to  redeem  on  December  18,  2006  $15 million of other trust preferred
securities  with  a  fixed  rate  of 9.88%. The net effect of these actions will
reduce  annual  interest expense by $0.8 million going forward. Upon redemption,
$0.4  million  of  related  unamortized  issuance  costs will be expensed in the
fourth  quarter  of  2006.  At  such  time,  there  will be $55 million of trust
preferred securities outstanding, compared to $70 million at September 30, 2006.

     Total  consolidated stockholders' equity at September 30, 2006 increased by
13%  to  $154.4  million  from $136.2 million at December 31, 2005. The increase
resulted from $17.7 million of net earnings and $0.5 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
     September  30,  2006  and  2005  totaling  $3,129,000  and  $4,572,000,
     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  200,000 in the 2006 EPS computations and 337,000 in the 2005
     EPS  computations.

(3)  Returns  for  the  quarterly  and  nine-month periods have been annualized.

(4)  Represents  noninterest  expenses (excluding the provision for loan losses)
     as  a  percentage  of  net  interest  and  dividend income plus noninterest
     income.  Noninterest  expenses  for  the  2006  periods included a one-time
     charge  of  $1.5  million.
