no cost or expense to Landlord, with all directions, laws, ordinances, orders,
rules, regulations and requirements of all federal, state, county or municipal

or representatives upon twenty-four (24) hours prior written notice to enter
into and upon any part of the Premises at all reasonable hours (and in
emergencies at all times) to inspect, repair and/or clean the same, to show the
Premises to prospective purchasers, mortgagees, tenants, or insurers, or make
alterations or additions thereto, and Tenant shall not be entitled to any
abatement or reduction of rent by reason thereof.

of the date hereof, it is the owner in fee simple of the Premises and that it
has the right to enter into this Lease and to perform the obligations of
Landlord set forth herein. Nothing herein shall be construed as prohibiting
Landlord from further encumbering Landlord's reversionary interest by a deed of
trust and or mortgage, or from assigning the rents and profits hereunder.

          3.6 Miscellaneous Restrictions. Tenant agrees in using the Premises
not to commit any waste or suffer any waste to be committed upon the Premises,
nor to do or permit anything to be done on or about the Premises which will in

permit to be used the Premises in any manner so as to create a hazard of fire or
other casualty, nor to cause, maintain or permit any nuisance in, on or about
the Premises.

to the plans and specifications attached (or to be attached) hereto as Exhibits
"C" and "C-l" and incorporated herein by reference ("Improvements") at Tenant's
expense. In the event the plans and specifications are not attached to this
Lease as of the date of execution hereof, this Lease shall terminate at
Landlord's option, on the day next following the 14th day Tom the date hereof
unless Landlord and Tenant initial and attach the plans and specifications to
this Lease on or before such date. "Building Grade" and/or "Building Standard"
shall mean the type, brand, and/or quality of the materials Landlord designates

plans and specifications), Tenant shall pay the cost of all Tenant Improvements
and any ad valorem taxes and increased insurance thereto.

          4.3 Delay in Completion. (a) If by the date specified in Section 2.1
the Improvements have not been substantially completed pursuant to the plans
described on Exhibits "C" and "C-l", and a certificate of occupancy issued by
the City of Kansas City, Missouri, due to omission, delay or default by Tenant
or anyone acting under or for Tenant, Landlord shall have no liability, and the
obligations of this Lease (including without limitation, the obligation to pay
rent) shall nonetheless commence as of the date specified in Section 21(i).

          (b) If the Improvements are not substantially completed pursuant to
the specifications contained in Exhibits "C" and "C-l", and a certificate of
occupancy issued by the City of Kansas City, Missouri, due to any reason other
than an omission, delay or default by Tenant or someone acting under or for
Tenant, then, as Tenant's sole remedy for the delay in Tenant's occupancy of the
Premises, Commencement Date shall be delayed as set forth in Section 2.1 and the
rent herein provided shall not commence until the earlier to occur of actual
occupancy by Tenant or substantial completion of the Improvements.

          4.4 Ownership of Improvements. Unless Landlord requires their removal
pursuant hereto or unless Tenant notifies Landlord in writing and obtains
Landlord's consent prior to making any such alterations of its intent to remove
same upon termination of this Lease, all alterations, repairs, additions,
utility installations, fixtures (except for movable equipment or furniture owned
by Tenant) and improvements of any nature to the Premises shall, at the
expiration or earlier termination of this Lease, become the sole property of
Landlord and remain upon and be surrendered with the Premises. Landlord shall
not, in any way, be responsible for reimbursement to Tenant for any of Tenant's
alterations, repairs, additions, improvements, utility installations, fixtures

         5.1 Base Rental. Subject to the adjustments to Net Rentable Area set
forth in Section l.l (b) and Section l. l (d) and the limitations to such
adjustments set forth therein, Tenant agrees to pay to Landlord during the
Initial Lease Term, without prior demand therefore and without any offset or
deduction whatsoever, the monthly rent set forth below, as adjusted under
Section 5.2 hereof ("Base Rental"):

                Rent per
Monthly Rent    Square Foot    Time Period
------------    -----------    -----------

   0            0              Commencement Date through Month 3
$5,383.91       $23            Month 4 through Month 36

          The monthly Base Rental for each month, or portion thereof during the
Initial Lease Term, together with any estimated adjustments pursuant to Section
5.2 hereof, shall be due and payable in advance on the first day of each
calendar month during the Initial Lease Term and any extensions or renewals
thereof, and Tenant hereby agrees to pay such Base Rental and any adjustments
thereto to Landlord at Landlord's address provided herein (or such other address
as may be designated by Landlord in writing from time to time). The Base Rental
for the first month of the Lease Term for which Base Rental is due has been
deposited with Landlord by Tenant contemporaneously with the execution hereof If
the term of this Lease commences on a day other than the first day of the month
or terminates on a day other than the last day of the month, then the
installments of Base Rental and any adjustments thereto for such month or months
shall be prorated, based on the number of days in such month, and Landlord shall
return any overpayment made by Tenant.

          5.2 Additional Rent Adjustments. The Base Rental payable hereunder
shall be adjusted upward from time to time in accordance with the following
provisions:

          (a) Tower II contains 240,914 square feet of Net Rentable Area in
aggregate. Tenant's Base Rental is based, in part, upon the estimate that annual
Operating Costs (hereinafter defined) will be equal to $5.00/square foot of Net
Rentable Area in Tower II. Tenant shall, during the term of this Lease, pay as
an adjustment to Base Rental hereunder an amount (per each square foot of Net
Rentable Area within the Premises, including those portions of Common Areas
allocated to the Premises from time to time) equal to the excess of actual
Operating Costs per square foot in Tower II over the amount of $5.00/square foot
("Additional Rent"). Landlord may collect any Additional Rent in arrears on a
yearly basis. Landlord shall also have the option to make a good faith estimate
of the Additional Rent for each upcoming calendar year based on the actual
Operating Costs for the preceding calendar year, and may require the monthly
payment of Base Rental adjusted in accordance with such estimate of Additional
Rent. Any amounts paid based on such an estimate shall be subject to adjustment
pursuant to Subsection 5.2(b) when actual Operating Costs are available for each
calendar year.

          (b) If the actual Operating Costs in the previous calendar year are
more than the amount paid by Tenant through the course of the year, Tenant
agrees to pay the difference within ten (10) days of such determination. If the
actual Operating Costs in the previous calendar year are less than the amount
paid by Tenant and Tenant has overpaid Landlord, the amount of such overpayment
shall be credited to Tenant's continuing payments of Additional Rent until
exhausted, except that for the final year of the


                                       5
<PAGE>


Initial Lease Term, or any extension thereof, any overpayment will be rebated to
Tenant, provided Tenant shall not be in default under the Lease.

          For the purpose of determining the Additional Rent under this Lease,
the term "Operating Costs" shall mean all direct and indirect costs and expenses
in each calendar year of operating, maintaining, repairing, managing and owning
Tower II, the first floor of the link building between Twentieth Century Tower I
and Tower II and the Exterior Common Areas. "Exterior Common Areas" shall mean
those areas of the Real Proper SEW are not located within Tower II and which are
provided and maintained for the common use and benefit of Landlord and tenants
of Tower II generally and the employees, invitees and licensees of Landlord and
such tenants including, without limitation, all parking areas, enclosed or
otherwise and all streets, sidewalks and landscaped areas located within the
Real Property. Operating Costs shall not include the cost of any capital
improvements, depreciation, interest, and principal payments on mortgage and
other non-operating debts of Landlord. Operating Costs shall, however, include
the amortization of capital improvements which are primarily for the purpose of
reducing Operating Costs, or which are required by governmental authorities. The
Operating Costs shall include, but are not limited to, the following:

         1. The wages and salaries (including insurance benefits, vacation and
         sick leave) of all employees directly engaged in the operation and
         maintenance of the Premises, including employers' social security taxes
         and any other taxes which may be levied on such wages and salaries.

         2. The cost of all property management fees and maintenance and service
         agreements covering the Premises, including, but not limited to,
         equipment maintenance.

         3. Insurance premiums for fire, extended coverage and general liability
         coverage and for such other coverage with respect to the Premises that
         Landlord reasonably deems desirable, and legal and accounting expenses
         directly related to the Premises.

         4. The cost of repairs and general maintenance of the Premises
         including, but not limited to, those services enumerated in Sections
         6.1 and 6.2 (exclusive of expenses to accommodate other tenant(s)), and
         all other reasonable costs and expenses incurred by Landlord in
         performing its obligations hereunder. 5. All taxes and assessments
         (excluding penalties not due to the fault of Tenant), and governmental
         charges whether federal, state, county or municipal, which are levied
         on or charged against the Real Property, personal property, or rents,
         or on the right or privilege of leasing real estate or collecting rents
         thereon, and any other taxes and assessments attributable to the
         Premises, excluding, however, federal and state income taxes.

          The taxes and assessments allocable to the Operating Costs which are
to be paid by Tenant shall be the sum of the following:

          (i) the product obtained by multiplying the taxes assessed against the
Real Property by a fraction, the numerator of which is the total number of
square feet of floor area within the Premises, and the



                                       6
<PAGE>

denominator of which is the total number of square feet of floor area contained
within all of the improvements on the Real Property; plus

          (ii) the product obtained by multiplying the taxes and assessments
assessed against the improvements on the Real Property by a fraction, the
numerator of which is the total number of square feet of floor area contained
within the Premises, and the denominator of which is the total number of square
feet of floor area contained within all of the improvements on the Real
Property.

          (c) Tenant shall have the right, upon ten (10) days' written notice to
Landlord, to audit the books and records of Landlord relating to Operating Costs
during the year preceding the audit. Such audit shall be performed at the sole
expense of Tenant, within twenty-four (24) months after the end of the calendar
year for which such records are being questioned, no more than one time per year
and at the location where such books and records are normally kept by Landlord.
In the event such an audit demonstrates Additional Rent collected for such
preceding year to be higher or lower than the amount of Additional Rent actually
due pursuant to Subsection 5.2(a) above, then Landlord shall refund any
overpayment or Tenant shall remit any underpayment within ten (10) days of such
determination.

          5.3 Interest on Past Due Rent. If Tenant shall fail to pay within ten
(10) days after the same is due and payable any Base Rental or any Additional
Rent, Tenant shall, upon demand, pay Landlord interest on the past due amount
from the due date thereof to the date of payment at a rate equal to the lesser
of (i) two percent (2%) in excess of the prime rate Tom to time announced by
Boatmen's First National Bank of Kansas City, or (ii) the highest lawful rate
that may be charged to Tenant under the laws of the State of Missouri.

shall be furnished to Tenant by Landlord with Tenant bearing the entire actual
cost of additional service allocable to the Premises as such costs are

Landlord's charge for similar additional services to any other user of space in
Tower II);

          (b) Routine maintenance and electric lighting service for all Exterior
Common Areas, Common Areas and Service Areas in the manner and to the extent
deemed by Landlord to be standard;

<PAGE>

          (c) Janitor service, Mondays through Fridays, exclusive of normal
business holidays; provided, however, that janitorial services shall not include

upon presentation of a statement therefor by Landlord. Tenant shall cooperate
with Landlord's employees in the furnishing by Landlord of janitorial services

included in the Operating Costs). Landlord agrees to provide Tenant with master
entry cards which shall be surrendered upon the expiration or earlier
termination of this Lease. Any lost cards shall be cancelled and Tenant shall
pay Landlord the sum of Fifteen and no/100 Dollars ($15.00) for each additional
replacement card(s). Landlord shall have no liability to Tenant, its employees,
agents, invitees or licensees for losses due to theft or burglary, or for
damages done by unauthorized persons on the Premises and neither shall Landlord
be required to insure against any such losses. Tenant shall fully cooperate in
Landlord's efforts to maintain security in Tower II and shall follow all
regulations promulgated by Landlord with respect thereto; and

          (g) Maintenance services including, but not limited to, lawn care,
landscaping, parking lot cleaning and striping and exterior water.

          The failure by Landlord to any extent to furnish or the interruption
or termination of these defined services in whole or in part, resulting Tom
causes beyond the reasonable control of Landlord, shall not render Landlord
liable in any respect nor be construed as an eviction of Tenant, nor work an
abatement of rent, nor relieve Tenant from the obligation to fulfill any
covenant or agreement hereof Should any of the equipment or machinery used in
the provision of such services for any cause cease to function properly, Tenant
shall have no claim for offset or abatement of rent or damages on account of an
interruption in service occasioned thereby or resulting therefrom.

          6.2 Obligation to Repair Maintain. Except for damage caused by any
negligent or intentional act or omission of Tenant, Tenant's agents, employees,
or invitees, Landlord (at Landlord's expense) shall keep in reasonably good
order, condition and repair (including replacement if necessary) the

                              OBLIGATIONS OF TENANT

          7.1 Care of the Premises by Tenant. Tenant shall, at Tenant's sole
cost and expense, keep the Premises and every part thereof in good condition and
repair. Tenant agrees not to commit or allow any waste to be committed on any
portion of the Premises, and at the termination of this Lease to deliver up the

Tenant's agents, employees, invitees, or visitors, and such repairs shall
restore Tower II to as good a condition as it was in prior to such damage, and
shall be effected in compliance with all applicable laws; provided, however, if
Tenant fails to make such repairs or replacements promptly, Landlord may, at its
option, make repairs or replacements, and Tenant shall pay the cost thereof to
the Landlord on demand. Tenant agrees with Landlord not to make or allow to be
made any alterations or additions to the Premises, other than the Improvements,
without first obtaining the written consent of Landlord in each such instance,
which consent may be given on such conditions as Landlord may elect but which
consent shall not be unreasonably withheld. Landlord's approval of any plans,
specifications or working drawings for Tenant's alterations shall create no
responsibility or liability on the part of Landlord for their completeness,
design sufficiency or compliance with all laws, rules and regulations of
governmental agencies or authorities. Landlord may require Tenant to remove any
and all fixtures, equipment and other improvements installed on the Premises. In
the event that Landlord so elects, and Tenant fails to remove such improvements,
Landlord may remove such improvements at Tenant's cost, and Tenant shall pay
Landlord on demand the cost of restoring the Premises to Building Standard.

          7.3 Use of Electrical Services by Tenant. The Premises are designed to
provide standard office electrical facilities and standard office lighting.

average of 2 watts per square foot.



                                       9
<PAGE>

          (c) If Tenant's consumption of electrical services exceeds either the
rated capacities and/or design loads as per Subsections 7.3(a) and 7.3(b), or
generates heat in excess of that Landlord's air conditioning system is designed
to handle, then Tenant shall remove such equipment and or lighting to achieve
compliance within ten (10) days after receiving notice from Landlord, or upon
receiving Landlord's prior written approval, such equipment and/or lighting may
remain in the Premises, subject to the following:

          (i) Tenant shall pay for all costs of installation and maintenance of
submeters, wiring, additional air conditioning systems and other items required
by Landlord, in Landlord's discretion, to accommodate Tenant's excess design
loads and capacities or heat production.

          (ii) Tenant shall pay to Landlord, upon demand, the cost of the excess
demand and consumption to electrical service at rates determined by Landlord
(which rates shall be in accordance with any applicable laws) as well as all
costs of operating additional air conditioning systems deemed necessary by
Landlord on account of Tenant's excess consumption.

          (iii) Landlord may, at its option, upon not less than thirty (30)
days' prior written notice to Tenant, discontinue the availability of such
extraordinary utility service. If Landlord gives any such notice, Tenant will
contract directly with such public utility for the supplying of such utility
service to the Premises.

          7.4 Building Rules. Tenant will comply with the rules of Tower II and
the Real Property adopted and altered by Landlord from time to time and will
cause all of its agents, employees, invitees and visitors to do so. All changes
to such rules will be sent by Landlord to Tenant in writing with the initial
rules being attached hereto as Exhibit "D" and incorporated herein by reference.

                                  ARTICLE VIII

                              DAMAGE OR DESTRUCTION

          8.1 Damages Covered by Insurance. (a) If the Premises or any part
thereof shall be damaged by fire or other casualty, Tenant shall give prompt
written notice thereof to Landlord. In case Tower II shall be so damaged that
substantial alteration or reconstruction of Tower II shall, in Landlord's sole
opinion, be required (whether or not the Premises shall have been damaged by
such casualty) or in the event any mortgagee of Landlord's should require that
the insurance proceeds payable as a result of a casualty be applied to the
payment of the mortgage debt then, Landlord may repair and restore the Premises,
with rent and other charges payable by Tenant during this period abated or
equitably reduced as set forth in Section 8.3, or terminate this Lease as
provided in Subsection 8.1(b). If Landlord does not elect to terminate this
Lease, then Landlord shall within thirty (30) days after the occurrence of such
damage or destruction give notice to Tenant of the date by which Landlord
reasonably believes that restoration of the Premises and/or Tower II shall be
substantially completed (such date being herein referred to as the "Restoration
Date"). If such notice indicates that the Restoration Date shall not be on or
before a date which shall be ninety (90) days following the date of such damage
or destruction, then, Tenant shall have the right to terminate this Lease by
giving notice to Landlord not later than twenty (20) days after


                                       10
<PAGE>


receiving such notice, and in the event Tenant gives such notice, this Lease
shall be deemed terminated as of the date ten (10) days after Landlord's receipt
of Tenant's termination notice as if such date were the expiration date of the
Lease; provided, however, that Tenant shall have no right of termination in the
event the damage or destruction affects a part of Tower II that does not include
the Premises and does not impact Tenant's use of or access to the Premises. If
the foregoing proviso does not apply and Tenant has the right to termination but
does not elect to terminate this Lease, but Landlord shall thereafter fail to
substantially complete the restoration of the Premises and/or Tower II within
ninety (90) days following the date of such damage or destruction, then Tenant
shall have the right to terminate this Lease by giving written notice to
Landlord not later than one hundred (100) days following the date of the damage
or destruction and if Landlord shall fail to so complete such restoration within
fifteen (15) days following Landlord's receipt of Tenant's termination notice,
this Lease shall be deemed terminated as of the date of the casualty as if such
date were the expiration date of the Lease. The Premises shall be repaired and
restored by Landlord to substantially the same condition in which it was
immediately prior to the happening of the casualty, except that Landlord's
obligation to pay for such restoration shall not exceed the scope of the work
required to be done by Landlord at Landlord's expense in originally constructing
Tower II and installing the Improvements. Tenant shall pay to Landlord, on
demand, the cost of the reconstruction of all improvements in excess of those
Improvements originally installed at Landlord's expense, and Tenant shall be
responsible for the restoration of Tenant's furniture, equipment and other
personal property.

          (b) Landlord may elect to terminate this Lease pursuant to Subsection
8.1 (a) by giving notice to Tenant of its election to do so within thirty (30)
days after such occurrence. If Landlord exercises its right to terminate this
Lease, then this Lease shall cease, effective as of the date of such damage or
destruction, and all rent and other charges payable by Tenant shall be adjusted
as of that date.

          8.2 Damages Not Covered by Insurance. (a) If the Premises shall be at
any time damaged or destroyed by a casualty uninsured under the insurance
provisions of Article XI, so as to become partially or totally untenantable,
then Landlord shall have the right of either (i) repairing and restoring the
Premises, with rent and other charges payable by Tenant during this period
abated or equitably reduced as set forth in Section 8.3, or (ii) terminating
this Lease. Said election shall be made by Landlord within thirty (30) days of
Tenant's notice to Landlord of the occurrence of such casualty by giving notice
thereof to Tenant within such period.

          (b) If Landlord elects to rebuild and repair the Premises as set forth
in Subsection 8.2(a), then Landlord shall within thirty (30) days after the
occurrence of such damage or destruction give notice to Tenant of the date by
which Landlord reasonably believes that restoration of the Premises and/or Tower
II shall be substantially completed (such date being herein referred to as the
"Restoration Date"). If such notice indicates that the Restoration Date shall
not be on or before a date which shall be ninety (90) days following the date of
such damage or destruction, then, Tenant shall have the right to terminate this
Lease by giving notice to Landlord not later than twenty (20) days after
receiving such notice, and in the event Tenant gives such notice, this Lease
shall be deemed terminated as of the date ten (10) days after Landlord's receipt
of Tenant's termination notice as if such date were the expiration date of the
Lease; provided, however, that Tenant shall have no right of termination in the
event the damage or destruction affects a part of Tower II that does not include
the Premises and does not impact Tenant's use of or access to the Premises. If
the foregoing proviso does not apply and Tenant has the right to termination



                                       11
<PAGE>

but does not elect to terminate this Lease, but Landlord shall thereafter fail
to substantially complete the restoration of the Premises and/or Tower II within
ninety (90) days following the date of such damage or destruction, then Tenant
shall have the right to terminate this Lease by giving written notice to
Landlord not later than one hundred (100) days following the date of the damage
or destruction and if Landlord shall fail to so complete such restoration within
fifteen (15) days following Landlord's receipt of Tenant's termination notice,
this Lease shall be deemed terminated as of the date of the casualty as if such
date were the expiration date of the Lease Landlord shall be required to
complete the repair and restoration of Tenant's property to substantially the
same condition in which it was immediately prior to the happening of the
casualty, except that Landlord's obligation to pay for such restoration shall
not exceed the scope of the work required to be done by Landlord at Landlord's
expense in originally constructing Tower II and installing the Improvements.
Tenant shall pay to Landlord, on demand, the cost of the reconstruction of all
improvements in excess of those Improvements originally installed at Landlord's
expense, and Tenant shall be responsible for the restoration of Tenant's
furniture, equipment and other personal property.

          (c) If Landlord elects to terminate this Lease, then this Lease shall
terminate effective as of the date of the occurrence of the casualty and the
rent and other charges payable by Tenant shall be adjusted as of the date of
such casualty.

          8.3 Abatement or Reduction in Rent. If this Lease is not terminated as
set forth in Subsection 8.1(b) or Subsection 8.2(c), then (and as Tenant's sole
right against Landlord by reason of such damage or destruction), the annual rent
and other charges hereunder shall be abated or equitably reduced during any
period in which the Premises are rendered wholly or partially untenantable to
the extent such damage or destruction interferes with the operation of Tenant's
business in the Premises; provided, however, if the Premises or any other
portion of Tower II be damaged by fire or other casualty resulting from the
fault or negligence of Tenant or any of Tenant's agents, employees, or invitees,
the rent hereunder shall not be diminished during the repair of such damage and
Tenant shall be liable to Landlord for the cost of the repair and restoration of
Tower II caused thereby to the extent such cost and expense is not covered by
insurance proceeds. Such abatement or reduction shall continue for the period
commencing with such destruction or damage and ending fifteen (15) days after
Landlord completes its repair or restoration as set forth in Subsection 8.1(a)
or Subsection 8.2(b), or when Tenant reopens the Premises for business,
whichever is earlier. Landlord shall not be liable for any inconvenience or
annoyance to Tenant or injury to the business of Tenant resulting in any way
from such damage or the repair thereof, except with respect to the fair
diminution of rent during the time and to the extent the Premises are wholly or
partially untenantable.

                                   ARTICLE IX

                                  CONDEMNATION

          9.1 Total Taking If the whole of Tower II or the Premises shall be
condemned by eminent domain for any public or quasi-public use or purpose or be
conveyed in lieu thereof, then the term of this Lease shall terminate as of the
date possession shall be taken by the acquiring authority, and all rent and
other charges hereunder shall be adjusted as of that date.



                                       12
<PAGE>

          9.2 Partial Taking If twenty percent (20%) or more of Tower II shall
be acquired or condemned as aforesaid, and if such partial taking or acquisition
renders the Premises unsuitable for the operation of Tenant's business therein,
then the term of this Lease shall terminate as of the date possession shall be
taken by the acquiring authority, and Base Rental and other charges shall be
adjusted as of the date of such termination. In the event of a partial taking or
acquisition which is not extensive enough to render Tower II or the Premises
unsuitable for such use then Landlord shall, to the extent only of the
condemnation proceeds received by Landlord, promptly restore Tower II and
Premises to a condition comparable to its condition at the time of such
condemnation, less the portion lost in the taking, and this Lease shall continue
in full force and effect and the rent shall be reduced in the same proportion
that the floor area remaining in the Premises after the taking bears to the
floor area in the Premises immediately prior to such taking.

          9.3 Condemnation Award. In the event of any condemnation or conveyance
in lieu thereof of the Premises, whether whole or partial, Tenant shall have no
claim against Landlord or the condemning authority for the value of the
unexpired Lease Term, and Tenant shall not be entitled to any part of the
compensation or award, whether paid as compensation for diminution in value to
the leasehold or to the fee of the Premises, and Landlord shall receive the full
amount thereof, Tenant hereby waiving any right to any part thereof and
assigning to Landlord its interest therein; provided, however, (i) Tenant shall
have the right to claim and recover from the condemning authority (but not from
Landlord) such compensation as may be separately awarded to Tenant in Tenant's
own name and right on account of all damage to Tenant's business by reason of
the condemnation and any cost which Tenant may incur in removing its personal
property from the Premises including the increase, if any, of the lease rate for
the new premises over the Base Rental described in Section 5.1, for the duration
of the Initial Lease Term or any extension thereof; and (ii) if this Lease is
terminated by reason of a condemnation of all or a part of the Premises,
Landlord shall pay to Tenant, to the extent of the condemnation award only,
Tenant's unamortized cost of installing permanent leasehold improvements (less
Landlord's contribution toward the Improvements) in the Premises as disclosed on

additional locks thereon or by such other action as Landlord shall determine to
be reasonable to secure the Premises, and no such action taken to secure the
Premises shall be deemed an exclusion of Tenant Mom the Premises, nor shall any

Premises and to terminate this Lease; or

         (f) Exercise all other remedies available to Landlord at law or in
equity, including, without limitation, injunctive relief of all varieties. All
Landlord's remedies shall be cumulative and not exclusive. Forbearance by

regulations and building codes applicable to Tower II ("Applicable Law"). The

shall continue to submit names to Landlord until the Architect and the Engineer
are finally approved by Landlord and written consent has been delivered to and
received by Tenant. Landlord hereby approves Rees Architecture as the Architect
and the parties agree that no Engineer will be utilized for the Improvements.

Plan for Landlord's review and approval. Landlord shall either approve or
disapprove the Space Plan within ten (10) days of receipt, for reasonable and
material reasons (which shall be limited to the following: (i) adverse effect on
the structural integrity of Tower II (ii) possible damage to the Tower II
systems, (iii) non-compliance with applicable codes; (iv) adverse affect on the
appearance of Tower II [each a "Design Problem"]) and return the Space Plan to
Tenant. In the event of a disapproval of the Space Plan, Tenant shall make the
changes necessary in order to correct the Design Problem(s) and shall return the
Space Plan to Landlord, which Landlord shall approve or disapprove within three
(3) days of receipt. This procedure shall be repeated until the Space Plan is
finally approved by Landlord and written approval has been delivered to and
received by Tenant.

<PAGE>

          (3) PREPARATION AND APPROVAL OF WORKING DRAWINGS. After the final
Space Plan approval by Landlord, Tenant shall submit to Landlord drawings and
specifications prepared by the Architect, at Tenant's expense ("Working
Drawings"), which shall be compatible with the design, construction and
equipment of Tower II, comply with all laws, be capable of logical measurement
and construction, contain all such information as may be required for the
construction of the Tenant Improvements, and contain all partition locations,
plumbing locations, air conditioning system and duct work, special air
conditioning requirements, reflected ceiling plans, office equipment locations,
and special security systems. Landlord shall approve the Working Drawings, or
such portion as has from time to time been submitted, or designate by notice
given to Tenant the specific changes reasonably required to be made to the
Working Drawings in order to correct any Design Problem and shall return the
Working Drawings to Tenant within ten (10) days of receipt. In the event of a
disapproval of the Working Drawings, Tenant shall make the changes necessary in
order to correct any such Design Problem(s) and shall return the Working
Drawings to Landlord, which Landlord shall approve or disapprove within three
(3) days of receipt. This procedure shall be repeated until all of the Working
Drawings are finally approved by Landlord and written approval has been
delivered to and received by Tenant.

          (1) CONTRACTOR. Landlord shall, within fifteen (15) days of receipt of
Tenant's Working Drawings ("Final Plans"), provide Tenant an estimate of the
cost of constructing the Improvements. Tenant shall pay for the entire cost of
the Tenant improvements in excess of the tenant finish allowance ("TFA") as
provided in Section 4.1 of the Lease.

          (2) LANDLORD'S REVIEW RESPONSIBILITIES. Tenant agrees and understands
that the review of all plans pursuant to this Agreement by Landlord is solely to
protect the interests of Landlord in Tower II and the Premises, and Landlord
shall not be the guarantor of, nor responsible for, the correctness or accuracy
of any such plans or compliance of such plans with Applicable Laws.

          (1) AMOUNT Landlord shall provide on behalf of Tenant the TFA as set
forth in Section 4.1 of the Lease.

          (2) USE. Tenant may use the TFA solely for the purpose of paying for
the services provided by the Architect, Contractor and Engineer described above,
and the construction of, and the costs of materials used in the construction of,
the Tenant Improvements.

          (3) DISBURSEMENT OF TFA. Landlord shall disburse to Tenant, within
thirty (30) business days of receipt by Landlord of a written request for
payment of fees to the Architect, accompanied by conditional lien releases in
connection therewith (and unconditional lien releases with respect to the prior
month's payment), payment equal to each request for payment, not to exceed the
total TFA to be provided by Landlord. Tenant shall be entitled to submit
requests for payments with respect to fees paid to the Architect monthly. Prior

values for the work similar in form and content to A.I.A. Document No. G702
(Contractor's Application for Payment) itemizing the cost of the work by trade
category and specifying the cost of the work as estimated by the Architect. If
Landlord serves as the Contractor, Landlord shall pay its subcontractors in full
directly until the total TFA is exhausted. Thereafter, Landlord shall continue
to pay its subcontractors in full directly but shall submit progress billings to
Tenant for the work completed to date based on the schedule of values, and
Tenant shall pay such progress billings to Landlord within thirty (30) days of
receipt. Landlord shall not have any obligation to disburse any of the TFA at
any time while Tenant is in default under the Lease or following any event or
occurrence which, with the passage of time or the giving of notice or both, will
ripen into or constitute a default under the Lease; provided, however, that if
Tenant is granted the right to cure or correct the event or occurrence which,
with the passage of time or the giving of notice or both, will ripen into or
constitute a default under the Lease, then if Tenant shall so cure or correct
such event or occurrence within the time periods provided herein, Tenant shall
have the right, following the completion of such cure or correction of such
event or occurrence, to again receive disbursements of the TFA as provided
herein. In no event shall Landlord be obligated to expend or disburse any amount
in excess of the TFA in connection with the work and the construction of the
Tenant Improvements.

IV. CHANGE ORDERS

          In the event that Tenant requests any changes in the Final Plans,
Landlord shall not unreasonably withhold its consent to any such changes, and
shall grant its consent to such changes, provided the changes do not create a
Design Problem.

V. INDEMNITY

          Tenant hereby releases and agrees to defend, indemnify and otherwise
hold Landlord harmless Tom any and all claims, costs, expenses, losses, damages
or liabilities, including reasonable attorneys' fees, arising From design and

         square foot of Net Rentable Area."

         3. The following new Section 22 shall be added to the Lease:

         "22. Second Security Deposit. Contemporaneously with the execution of
         this First Amendment, Tenant shall deposit Sixty Six Thousand and
         No/100 Dollars ($66,000.00) into an American Century-Benham Cash
         Reserve account in the name of Avax Technologies, Inc. and Tenant shall
         authorize Landlord's Senior Vice President of Facilities and Real
         Estate as co-signer with individual authority on such Cash Reserve
         account ("Second Security Deposit"). Such Second Security Deposit shall
         be in addition to the Security Deposit described in Section 13.3 of the
         Lease


<PAGE>



         and shall be additional security for the performance by Tenant of
         Tenant's covenants and obligations under this Lease, as amended, it
         being expressly understood that such Second Security Deposit shall not
         be considered an advance payment of rental or a measure of Tenant's
         damages in case of default by Tenant. Landlord may, from time to time,
         without prejudice to any other remedy, withdraw the Second Security
         Deposit to the extent necessary to make good any arrearages of rent or
         to satisfy any other covenant or obligation of Tenant hereunder.
         Following any such application of the Second Security Deposit, Tenant
         shall invest in the Cash Reserve account on Landlord's demand the
         amount so applied in order to restore the Second Security Deposit to
         its original amount. All interest and earnings on the Cash Reserve
         account shall be payable to Tenant. At the end of each quarter of each
         calendar year during the Initial Lease Term, Tenant has the right to
         withdraw from the Second Security Deposit in the Cash Reserve account;
         provided, however, at all times, the amount invested in such Cash
         Reserve account shall be equal to the Base Rental remaining due under
         the Initial Lease Term on the 1,327 square feet added under this First
         Amendment. If Tenant is not in default at the termination of this
         Lease, the balance of the Second Security Deposit remaining after any
         such application may be withdrawn by Tenant and Landlord's Senior Vice
         President of Facilities and Real Estate shall no longer be authorized
         on the Cash Reserve account. If Landlord transfers its interest in the
         Premises during the term of this Lease, Landlord may assign the Second
         Security Deposit to the transferee, and an authorized signer of such
         transferee shall be authorized on the Cash Reserve account in lieu of a
         representative of Landlord and thereafter Landlord shall have no
         further liability for the return of such Second Security Deposit.
         Notwithstanding the foregoing, Tenant may, at Tenant's option, in lieu
         of providing the Second Security Deposit in the form of cash invested
         in an American Century-Benham Cash Reserve account as described above,
         provide such Second Security Deposit in the form of an irrevocable
         letter of credit in a form satisfactory to Landlord from a commercial
         bank with a B Rating or better according to Scheshunoff Bank Quarterly
         or if no longer available, a similar publication satisfactory to
         Landlord, which will be converted to cash to be retained by Landlord,
         in the event of a default under this Lease, as amended. Such letter of
         credit may provide for a reduction at the end of each quarter of each
         calendar year during the Initial Lease Term from the amount required to
         be provided by Tenant following the effective date of this First
         Amendment; provided, however, at all times, the amount provided under
         such letter of credit shall be equal to the Base Rental remaining due
         under the Initial Lease Term on the 1,327 square feet added under this
         First Amendment."

         4. Article XX is hereby amended by deleting the fourth sentence and
replacing it with the following sentence:

         "Tenant shall have the option to lease from Landlord throughout the
         Initial Lease Term up to thirteen (13) spaces in such covered parking
         area, such spaces to be on a first come-first serve basis."

         5. Except as expressly modified by this First Amendment, Landlord and
Tenant agree that the Lease shall remain in full force and effect in accordance
with its terms, and that all terms used herein shall have the same meaning
ascribed to them as in the Lease.
