        NOW, THEREFORE, in consideration of the premises and the agreements

this Amendment shall have the respective meanings ascribed to them in the
Original Lease.

        2. (a) Surrender of the 4th Floor Premises. On the date (the "Surrender
Date") which is the later to occur of (i) November 1, 2003 and (ii) the date on
or before January 31, 2004 upon which Tenant vacates the 4th Floor Premises.
Tenant shall surrender to Landlord,
<PAGE>
and Landlord shall accept the surrender of, the Lease in respect of the 4th
Floor Premises and the term and estate thereby granted, together with the 4th
Floor Premises thereby demised, to the intent and purpose that the estate of
Tenant in and to the 4th Floor Premises shall be wholly extinguished and that
the term of the Lease in respect of the 4th Floor Premises shall expire on the
Surrender Date in the same manner and with the same effect as if such date were
the date set forth in the Lease in respect of the 4th Floor Premises for the
expiration of the term thereof. All fixed rent, additional rent and other
amounts payable under the Lease in respect of the 4th Floor Premises shall be
apportioned as of the Surrender Date.

     (b) On or before the Surrender Date, time being of the essence with respect

pay Landlord a monthly amount (a "Surrender Fee") equal to the difference
between (x) the fixed rent, Real Estate Tax escalation payments and Cost of
Operation and Maintenance escalation payments which would have been payable by
Tenant under the Original Lease with respect to the 4th Floor Premises for the
balance of the term of the Original Lease (i.e., through September 30, 2011)
(without giving effect to this Amendment) as applicable to the 4th Floor
Premises during the month in question and (y) the Fixed Rent, Tenant's Tax
Payments and Tenant's Operating Payments (as such terms are defined in the Lease
dated as of May 27, 1998, as modified by that certain First Amendment to Lease
dated as of October 10, 2003 (as so modified, the "Intervest Lease") between
Landlord and Intervest Bancshares Corporation ("Intervest")) set forth in the
Intervest Lease and payable for the period which would have constituted the
balance of the term of the Original Lease (i.e., through September 30, 2011)

Premises during the month in question (taking into account any free rent period
granted to Intervest, which shall have the effect of Tenant paying during such
free rent period the full fixed rent, Real Estate Tax escalation payments and

than the difference referred to above hereunder. The monthly Surrender Fee
shall be subject to adjustment based on adjustments to tax escalation payments
and operating expense payments under the Lease and the Intervest Lease. In the
event of any underpayment, Tenant shall pay such amount to Landlord within 20
days following the giving of such statement. In the event of any overpayment,
Landlord shall credit the amount thereof against subsequent installments of
rent due under the Lease.

any alterations, decorations, installations, additions and improvements in and
to the 4th Floor Premises, or any part thereof, including the Abandoned
Property, have been or will be encumbered in any way whatsoever, and that
Tenant owns and will own the Lease in respect of the 4th Floor Premises and the
Abandoned Property and has and will have good right to surrender the same on
the Surrender Date, and that no one other than Tenant has acquired or will
acquire through or under Tenant any right, title or interest in or to the 4th
Floor Premises, or any part thereof, or in or to said alterations, decorations,
installations, additions and/or improvements or any part thereof, including the
Abandoned Property.

     (e) Landlord shall accept the surrender of the 4th Floor Premises as of the
Surrender Date and in consideration of such surrender by Tenant and of the
acceptance of such surrender by Landlord, Tenant and Landlord do hereby mutually
release each other, their respective successors and assigns of and from any and
all claims, damages, obligations, liabilities, actions and causes of action, of
every kind and nature whatsoever arising under or in connection with the Lease
in respect of the 4th Floor Premises from and after the Surrender Date, except
that nothing herein contained shall be deemed to constitute a release or
discharge of Landlord or Tenant with respect to any obligation or liability (a)
accrued or incurred under the Lease in respect of the 4th Floor Premises and
outstanding and unsatisfied on the Surrender Date (including, without
limitation, any deficiency in Tenant's additional rent payments pursuant to

insurance and indemnification provisions of the Lease in respect of the 4th
Floor Premises or otherwise) arising prior to, on or after the Surrender Date as
a result of an event occurring or condition existing prior to or on the

Lease in respect of the 4th Floor Premises.

Landlord in accordance with the terms, covenants and conditions of this
