(lOth) floor of the Building ("Refusal Space").

years of the Expansion Term, if Landlord desires to accept a bona fide offer
from a third party ("Third Party Offer") to lease the Refusal Space or a portion
thereof, Landlord shall first give to Tenant notice that Landlord has received
such Third Party Offer and describing the terms and conditions of such Third
Party Offer ("Third Party Offer Notice"). Tenant may exercise the Right of
Refusal by giving Landlord written notice ("Exercise Notice") within five (5)
business days after receipt of the Third Party Offer Notice of Tenant's desire
to lease that portion of the Refusal Space set forth in the Third Party Offer.
Hereinafter the term "Refusal Space" shall be and shall mean the Refusal Space
or portion thereof set forth in the Third Party Offer.

          (c) Expansion Amendment. After receipt of the Exercise Notice,
Landlord and Tenant shall enter into an amendment of the Lease "Expansion
Amendment" acceptable to Land1ord and Tenant. Such Expansion Amendment shall
provide that from and after the applicable date on which the Refusal Space is

               Third Party Offer;

                                        3


<PAGE>


               (ii) Tenant's proportionate share of Excess Operating Expenses
               and other charges applicable to the Refusal Space shall be a
               fraction, the numerator of which shall be the number of rentable
               square feet in the Refusal Space and the denominator of which
               shall be the number of rentable square feet in the Building (as
               both shall be reasonably determined by Landlord);

               (iii) The Base Year applicable to the Refusal Space shall be as
               set forth in the Third Party Offer;

               (iv) Tenant shall accept the Refusal Space in the time, condition
               and manner described in the Third Party Offer;

               (v) Tenant's lease of the Refusal Space shall be for the term set
               forth in the Third Party Offer;

               (vi) Other applicable terms and conditions of the Third Party
               Offer shall modify the Lease; and

               (vii) For all purposes under the Lease, other than for the
               applicable calculations set forth above, the term "Premises"
               shall be deemed to include the Refusal Space.

          (d) Subordination. Tenant's Right of Refusal shall be subordinate to
any and all existing rights or interests conferred to other tenants for all or
any portion of the Refusal Space, as contained in any lease, or otherwise, in
effect on the effective date of this Amendment, including, without limitation,
(i) options or rights regarding renewal, extension or expansion and/or (ii)
subleases.

          (e) Failure to Exercise. If Tenant does not exercise its Right of
Refusal in the time and manner set forth herein, the Right of Refusal for that
portion of the Refusal space involving a Third Party Offer shall be deemed
terminated and of no further force or effect. Notwithstanding the prior sentence
to the contrary, however, after the expiration of six (6) months following the
date of each of Tenant's refusal or failure to accept or exercise its Right of
Refusal as herein provided, Tenant shall thereafter, subject to the provisions
of this Section, receive written notice from Landlord of Landlord's bona fide
intent, and the terms and conditions thereof, to lease to particular tenant
prospects the Refusal Space or any portions thereof not leased or otherwise
encumbered pursuant to a Third Party Offer.

          (f) No Default. Tenant may exercise the Right of Refusal, and an
exercisble thereof shall only be effective, provided that at the time of
Tenant's exercise of the Right of Refusal and on the date on which Tenant's
lease of the Refusal Space or any portion thereof commences, (i) the Lease is in
full force and effect, (ii) Tenant is not in default following any applicable
notice and the expiration of any applicable cure period hereunder and (iii) no
event has occurred which, with the giving of any applicable notice or passage of
time, would constitute a default.

          (g) Not Transferable. Tenant acknowledges and agrees that the Right
of~ Refusal shall be deemed personal to Tenant and if Tenant subleases, assigns
or otherwise transfers any interests hereunder to any person or entity prior to
the exercise of the Right of Refusal, the Right of Refusal shall lapse and be
forever waived.

     9.Renewal Option.
       ---------------

          (a) Renewal Option. Subject to the provisions hereinafter set forth,
Landlord hereby grants to Tenant an option ("Renewal Option") to extend the Term
on the same terms, conditions and provisions as contained herein, except as
otherwise provided below, for one (1) additional period of between three (3) and
five (5) years ("Renewal Term"), which Renewal Term shall commence on October 1,
2007 ("Renewal Commencement Date").

          (b) Renewal Notice. The Renewal Option shall be exercisable by written
notice ("Renewal Notice") from Tenant to Landlord of Tenant's election to
exercise the Renewal Option, which Renewal Notice must be given no earlier than
July 1, 2006 nor later than December 31, 2006. The Renewal Notice shall specify
the exact number of whole months in the Renewal Term (if no number of months is
specified, the Renewal Term shall be five (5) years). If Tenant fails to deliver
to Landlord the Renewal Notice within the prescribed time period, the Renewal
Option shall lapse and be forever waived.

          (c) Monthly Base Rent During the Renewal Term. Monthly Base Rent for
the Premises payable during the Renewal Term shall be equal to the prevailing
Market Rental Rate. For the Purposes of this Section 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, as determined by Landlord, for
comparable office space for terms commencing on or about the Renewal
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 rate first becomes effective, (iv) other
concessions customarily given to other renewing tenants including, without
limitation, rent abatement and tenant improvement allowances, and (v) other
comparable factors. Bona fide written offers to lease comparable space in the
Building received by Landlord from third parties (at arm's length) and
consummated between Landlord and such third party within six (6) months prior to
the date of the Renewal Notice may be used by Landlord or Tenant as an
indication of the Market Rental Rate. The components of the Market Rental Rate
may include, among other 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.

          (d) Broker Determination. No later than ten (10) days following
Landlord's receipt of the Renewal Notice, Landlord and Tenant shall meet in an
effort to negotiate, in good faith, the Market Rental Rate applicable to the
Premises. If Landlord and Tenant have not agreed upon the Market Rental Rate
applicable to the Premises within such (10) day period, then Landlord and Tenant
shall attempt to agree, in good faith, upon a single broker not later than
fifteen (15) days following Landlord's receipt of the Renewal Notice who shall
determine the Market Rental Rate for the Premises. If Landlord and Tenant are
unable to agree upon a single broker within such time period, then Landlord and
Tenant shall each appoint one broker not later than twenty (20) days following
Landlord's receipt of the Renewal Notice. Not later than twenty-five (25) days
following Landlord's receipt of the Renewal Notice, the two appointed brokers
shall appoint a third broker. If either Landlord or Tenant 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
within the prescribed time periods, then the first broker thereafter selected by
a party shall determine the Market Rental Rate. If a single broker is chosen,
then such broker shall determine the Market Rental Rate applicable to the
Premises. Otherwise, the Market Rental Rate shall be the arithmetic average of

                                        5




<PAGE>


two (2) of the three (3) determinations which are the closest in amount, and the
third determination shall be disregarded. Landlord and Tenant shall instruct
the brokers to complete their determination of the Market Rental Rate not 1ater
than forty (40) days following Landlord's receipt of the Renewal 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 Building is located and shall be a
licensed real estate broker.

          (e) Amendment to Lease. If Tenant validly exercises the Renewal
Option, Landlord and Tenant shall enter into a written amendment to the Lease
confirming the terms, conditions and provisions applicable to the Renewal 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.

          (f) No Default. Tenant may exercise the Renewal Option, and an
exercise thereof shall be effective, only if at the time of Tenant's exercise of
the Renewal Option and on the Renewal Commencement Date (i) the Lease is in full
force and effect, (ii) Tenant is not in Default, and (iii) no event has occurred
which, with the giving of any applicable notice or passage of time, would
constitute a Default.

          (g) Not Transferable. Tenant acknowledges and agrees that the Renewal
Option shall be deemed to be personal to Tenant and if Tenant subleases, assigns
or otherwise transfers any interest hereunder prior to the exercise of the
Renewal Option, such option shall lapse.

     10. Brokers. Tenant hereby represents and warrants to Landlord that Tenant
has not dealt with any real estate brokers or leasing agents, except Trammell
Crow Company of Denver, Inc., and Staubach Company ("Brokers"), in the
negotiation of this Amendment, and that no commissions are payable to any party
claiming through Tenant as a result of the consummation of the transaction
contemplated by this Amendment, except to Brokers, if applicable. Tenant hereby
agrees to indemnify and hold Landlord harmless from any and all loss, costs,
damages or expenses, including, without limitation, all attorneys' fees and
disbursements by reason of any claim of or liability to any other broker, agent,
entity or person claiming through Tenant (other than Brokers) and arising out of
or in connection with the negotiation and execution of this Amendment.

     11. Incorporation of Lease Terms; Conflict. With the exception of those
matters set forth in this Amendment, Tenant's leasing of the Premises shall be
subject to all terms, covenants and conditions of the Lease. In the event of any
express conflict or inconsistency between the terms of this Amendment and the
terms of the Lease, the terms of this Amendment shall control and govern.

     12. Ratification. Except as expressly modified by this Amendment, all other
terms and conditions of the Lease are hereby ratified and affirmed.

     13. Validity of Lease. The parties acknowledge that the Lease is a valid
and enforceable agreement and that Tenant holds no claims against Landlord or
its agents which might serve as the basis of any other set-off against accruing
rent and other charges or any other remedy at law or in equity.
