Lessee, the time of giving of such notice to be of the essence of this Section,
Lessee shall give Lessor written notice ("Offer Acceptance Notice") of its
election to lease the entire Office Space.

         (b) Amendment After receipt of any such Offer Acceptance Notice, Lessor
and Lessee shall enter into an amendment to the Lease acceptable to Lessor and
Lessee to provide that from and after the offer space Commencement Date (as
defined below), the Lease shall be deemed modified as follows:

         (1)      The term "Leased Premises" shall be deemed to include the
                  Offer Space.

         (2)      Base Rent payable for the Offer Space shall be equal to the
                  prevailing Market Rental Rate, as calculated in accordance
                  with Subsections (c) and (d) below, but in not event less than
                  the Monthly Base Rent in effect from time-to-time applicable
                  to the Leased Premises on per-square foot basis;

         (3)      Lessee's prorata share of operating expenses as set forth in
                  Section 2.02 of the Lease, shall be amended to reflect the

         (4)      Lessee shall accept the Offer Space "as is"; and

         (5)      The Offer Space Commencement Date shall be thirtieth (30th)
                  day following Lesor's receipt of Offer Acceptance Notice.

Except as set forth above, the terms and conditions of the Lease as they apply
to the Leased Premises shall govern Lessee's lease of the Offer Space.


                                       4
<PAGE>


         (c) Broker Determination. No later than five (5) business days
following Lessor's receipt of the Offer Acceptance Notice, Lessor and Lessee
shall meet in an effort to negotiate, in good faith, the market Rental Rate
applicable to the offer Space as of the date of the Offer Acceptance Notice. If
Lessor and Lessee have not agreed upon the Market Rental Rate applicable to the
Leased Premises within such five (5) day period, then Lessor and Lessee shall
attempt to agree in good faith, upon a single broker not later than ten (10)
days following Lessor's receipt of the offer Acceptance Notice who shall
determine the market Rental Rate for the Offer Space. If Lessor and lessee are
unable to agree upon a single broker within such time period, then Lessor and
Lessee shall each appoint one broker not later than fifteen (15) days following
Lessor's receipt of the Offer Acceptance Notice. Not later than twenty (20) days
following Lessor's receipt of the Offer Acceptance Notice the two appointed
brokers shall appoint a third broker. If either Lessor or Lessee fails to
appoint a broker within the prescribed time period, the single broker appointed
shall determine the Market rental Rate. If both parties fail to appoint brokers
with the prescribed time periods, then the first broker thereafter selected by a
party shall determine the Market Rental Rate. Otherwise, the Market Rental Rate
shall be the arithmetic average of two (2) of the three (3) determinations which
are the closest in amount, and the third determination shall be disregarded.
Lessor and Lessee shall instruct the brokers to complete their determination of
the Market Rental Rate not later than thirty (30) days following Lessor's
receipt of the Offer Acceptance Notice. Each party shall bear the costs of its
own broker, and the parties shall share equally the cost of the single or third
broker if applicable. Each broker shall have at least five (5) year's experience
in the leasing of commercial office buildings in the submarket in which the
Building is located and shall be a licensed real estate broker.


         (d) Market Rental Rate For the purposes of this Section 8 only, the
term "Market Rental Rate" per square foot of area shall mean the annual rate of
Monthly Base Rent reasonably determined to be the prevailing market rental rate
in the submarket in which the Building is located for comparable office space
for terms commencing on or about the Offer Space Commencement Date and shall
take into its consideration (i) the duration of the term for which such space is
being leased, (ii) location within the applicable building, (iii) when the
applicable first rate becomes effective, (iv) other concessions customarily
given to other tenants including, without limitation, rent abatement and tenant
improvement allowances, but assuming the leasing of the space is "as is" on the
Offer Space Commencement Date, and (v) other comparable factors. Bona Fide
written offers to lease comparable space in the Building received by lessor from
third parities (at arm's length) and consummated between Lessor and such third
party within six (6) months prior to the date of the Offer Acceptance Notice may
be used by Lessor or Lessee as an indication of the Market Rental Rate. The
components of the market Rental Rate may include, among other


                                       5
<PAGE>

items, the components of rent, periodic adjustments or additions to a fixed
Monthly Base Rent upon a share of real estate taxes and other expenses and
increases to adjust for inflation then customary in the submarket in which the
Building is located.

         (e) Failure to Exercise. In the event that Lessee fails to exercise its
right as aforesaid within five (5) business days of the date of the Offer Space
Notice is given to Lessee or, in the event Lessee shall have exercised its right
and Lessee shall not have executed an amendment of the ease as aforesaid within
five (5) business days from the date of the Lessee is given such an Amendment,
Lessee shall be deemed to have waived its right under this Section with respect
to the Offer Space.

         (f) Subordination Lessee's right to offer granted hereunder shall be
subordinate to any and all existing rights or interests conferred to other
tenants for all any portion of the offer Space, as contained in any lease, or
otherwise, in effect on the date of execution of the Lease including without
limitation, (i) options or right regarding renal, extensions or expansion, (ii)
subleases and (iii) assignments.

         (g) Not Transferable. Lessee acknowledges and agrees that any right of
offer granted herein shall be deemed personal to Lessee subleases, assigns or
otherwise transfers any interests under the Lease prior to the exercise of any
right to offer granted under this Section, such right shall lapse and be of no
other force or effect.

         (h) No Default. Lessee may exercise its right under this Section, and
such an exercise shall be effective, only if at the time of Offer Acceptance
Notice and on the Offer Space Commencement Date (i) the Lease is in full force
and effect, (ii) Lessee is not in default of any applicable notice or the
passage of time, would constitute such a default.

         9. Extension Option. Any and all other rights under this Section, and
such an exercise shall be effective, only if at the time of Offer Acceptance
Notice and on the Offer Space Commencement Date (i) the Lease is in full force
and effect, (ii) Lessee is not in default of any term or condition of the Lease,

Renewal Term on the same terms, conditions and provisions as contained herein,
except as otherwise provided below, for one (1) additional period of five


                                       6
<PAGE>

(5) years ("Extension Term"), which Extension Term shall commence on October 1,
2005 ("Extension Commencement Date") and end on September 30, 2010 ("Extension
Expiration Date")

         (b) Extension Notice. The Extension Option shall be exercisable by
written notice ("Extension Notice") from Lessee to Lessor of Lessee's election
to exercise the Extension Option, which Extension Notice must be given no
earlier than October 1, 2004 nor later than December 31, 2004. If Lessee fails
to deliver to Lessor the Extension Notice within the prescribed time period, the
Extension Option shall lapse and be forever waived.

         (c) Base Rent During the Extension Term. Base Rent for the Leased
Premises payable during the Extension Term shall be equal to the prevailing
Market Rental Rate, as hereinafter defined, but in no event less than the
Monthly Base Rent in effect immediately prior to the Extension Commencement
Date.

         (d) Broker Determination. No later than ten (ten) days following
Lessor's receipt of the Extension Notice, Lessor and Lessee shall meet in an
effort to negotiate, in good faith, the Market Rental Rate applicable to the
Leased Premises. If Lessor and Lessee have not agreed upon the Market Rental
Rate applicable to the Leased Premises within such (10) day period, then Lessor
and Lessee shall attempt to agree, in good faith, upon a single broker, not
later than fifteen (15) days following Lessor's receipt of the Extension Notice
who shall determine the Market Rental Rate for the Leased Premises. If Lessor
and lessee are unable to agree upon a single broker within such a time period,
then Lessor and Lessee shall each appoint one broker not later than twenty (20)
days following Lessor's receipt of the Extension Notice. Not later than
twenty-five (25) days following Lessor's receipt of the Extension Notice, the
two appointed brokers shall appoint a third broker. If either Lessor or Lessee
fails to appoint a broker within the prescribed time period, the single broker
shall determine the Market Rental Rate. If both parties fail to appoint brokers
with the prescribed time periods, then the first broker thereafter selected by a
party shall determine the Market Rental Rate. If a single is chosen, then such
broker shall determine the market Rental Rate applicable to the Leased Premises.
Otherwise, the Market Rental Rate shall be the arithmetic average of two (2) of
the three (3) determinations which are the closest in amount, and the third
determination shall be disregarded. Lessor and Lessee shall instruct the brokers
to complete their determination of the Market Rental Rate not later than forty
(40) days following Lessor's receipt of the Extension Notice. Each party shall
bear the costs of its own broker, and the parties shall share equally the cost
of the single or third broker if applicable. Each broker shall have at least
five (5) years' experience in the leasing of commercial office buildings in the
submarket in which the Buildings is located and shall be a licensed real estate
broker.

items, the components of rent, periodic adjustments or additions to a fixed
Monthly Base Rent based upon a share of real estate taxes and other expenses and
increases to adjust for inflation then customary in the applicable submarket.

         (f) Amendment to Lease. If Lessee validly exercised the Extension
Option, Lessor and Lessee shall enter into a written amendment to the Lease
confirming the terms, conditions and provisions applicable to the Extension
Term, as determined in accordance herewith, with such revisions to the rental
provisions as may be necessary to conform such provisions to the Market Rental
Rate.
