SECTION 1 - REGISTRANT'S BUSINESS AND OPERATIONS

ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On October 4, 2006, the registrant, Intervest Bancshares Corporation ("IBC") and
its  wholly owned subsidiary, Intervest Mortgage Corporation ("IMC"), executed a
letter  agreement  with  the  spouse  of  each company's former Chairman, Jerome
Dansker,  in  connection  with  each  company's obligation to pay death benefits
pursuant  to  the  terms of the employment agreements between Jerome Dansker and
those  two  companies.

The  employment  agreements  between  Jerome  Dansker  and IBC and IMC contained
similar  provisions  calling  for  the  payment to Jerome Dansker's spouse, Jean
Dansker,  of  an  amount called the "Distribution Amount" during a period called
the  "Distribution  Term." The Distribution Amount, in the case of IBC is 50% of
the amounts that would have been paid monthly to Jerome Dansker as salary by IBC
and  the  Distribution  Term  is  the  balance  of the term of the agreement, or
through June 30, 2014. In the case of IMC, the Distribution Amount is 25% of the
amounts  that  would  have  been paid to Jerome Dansker as salary by IMC and the
Distribution  Term  is  likewise  through  June  30,  2014.

The  letter  agreement  clarifies  that the contractual payments described above
will  be  paid  to  Jean Dansker in monthly installments during the Distribution
Term. In the letter agreement, Jean Dansker has agreed that, notwithstanding any
language  to  the  contrary  in the agreement, she will accept the death benefit
payments  in  the form of monthly payments during the Distribution Term, in full
satisfaction  of  the  obligations of IBC and IMC to Jean Dansker. The agreement
also  confirms  the  obligations  of  both  IBC  and  IMC,  in the event of Jean
Dansker's death prior to the end of the Distribution Term, to pay the balance of
any  remaining  Distribution  Amount  to  Jean  Dansker's  estate in a lump sum.

SECTION 7 - REGULATION FD

ITEM 7.01 REGULATION FD DISCLOSURE

As  a result of the death of the registrant's former Chairman in August 2006 and
the  letter  agreement  described  in  Section  1.01  above, the registrant will
recognize  a  consolidated  pre-tax  death benefit expense of approximately $1.5
million  in  its  fiscal  third  quarter  ended  September 30, 2006. This charge
represents  the  net  present  value of the total death benefit payments of $1.9
million  that  are  payable  to the Chairman's spouse through June 30, 2014. The
difference  between  the  net  present  value  and  the  total  payments will be
recognized  as  interest  expense  in  future periods through June 30, 2014. The
pre-tax  expense  of  $1.5  million  that  will  be recorded in the fiscal third
quarter  ended  September  30,  2006  is  less  than the $1.9 million previously
estimated  by  the  registrant  and reported in its Form 8-K filed on August 22,
2006.
