Landlord and Tenant acknowledge their respective maintenance and repair

and repair obligations shall become a Building Operating Expense.

         7.1.5 No expense items paid for by Tenant as Building Operating
Expenses shall be included in Landlord's calculation of Project Operating
Expenses, and no items paid for by Tenant as Project Operating


                                       8
<PAGE>   11

Expenses shall be included in Landlord's calculation of Building Operating
Expenses. Landlord shall use its good faith efforts to keep Operating Expenses
at a reasonable level.

         7.2.  Tenant shall pay to Landlord on the first day of each calendar
month of the Term, as Additional Rent, Landlord's estimate of Tenant's Pro Rata
Share of Building Operating Expenses and Tenant's Pro Rata Share of Project
Operating Expenses for such month.

               7.2.1 Within ninety (90) days after the conclusion of each
calendar year Landlord shall furnish to Tenant a statement showing in
reasonable detail the actual Operating Expenses and Tenant's Pro Rata Share of
Building Operating Expenses and Tenant's Pro Rata Share of Project Operating
Expenses for the previous calendar year. Any additional sum due from Tenant to
Landlord shall be due and payable no later than thirty (30) days after delivery
of such statement. If the amounts paid by Tenant pursuant to Section 7.2
exceeds Tenant's Pro Rata Share of Building Operating Expenses or Tenant's Pro
Rata Share of Project Operating Expenses, as applicable, for the previous
calendar year, Landlord shall, at Landlord's option, either (i) credit the
excess amount to the next succeeding installments of estimated Additional Rent,
or (ii) pay the excess to Tenant within thirty (30) days after delivery of such
statements.

               7.2.2 Any amount due under Section 7.2 for any period which is
less than a full month shall be prorated for such fractional month on the basis
of the actual number of days in the month.

         7.3.  Landlord's annual statement shall be final and binding upon
Tenant unless Tenant, within sixty (60) days after Tenant's receipt thereof,
shall contest any item therein by giving written notice to Landlord, specifying
each item contested and the reason therefor. If, during such sixty (60) day
period, Tenant reasonably and in good faith questions or contests the
correctness of Landlord's statement of Tenant's Pro Rata Share of Building
Operating Expenses or Tenant's Pro Rata Share of Project Operating Expenses,
Landlord will provide Tenant with access to Landlord's books and records
pertaining to Operating Expenses and such other information as Landlord
reasonably determines to be responsive to Tenant' questions. In the event that
after Tenant's review of such information, Landlord and Tenant cannot agree
upon the amount of Tenant's Pro Rata Share of Building Operating Expenses or
Tenant's Pro Rata Share of Project Operating Expenses, then Tenant shall have
the right to have an independent public accounting firm selected from among the
ten (10) largest in the United States hired by Tenant and approved by Landlord
(which approval shall not be unreasonably withheld or delayed) audit and/or
review such Landlord's books and records for the year in question (the
"Independent Review"). The results of any such Independent Review shall


                                       9
<PAGE>   12


be binding on Landlord and Tenant. If the Independent Review shows that
Tenant's Pro Rata Share of Building Operating Expenses or Tenant's Pro Rata
Share of Project Operating Expenses actually paid for the calendar year in
question exceeded Tenant's obligations for such calendar year, Landlord shall
at Landlord's option either (1) credit the excess amount to the next succeeding
installments of estimated Additional Rent or (2) pay the excess to Tenant
within thirty (30) days after delivery of such statement. If the Independent
Review shows that Tenant's payments of Tenant's Pro Rata Share of Building
Operating Expenses or Tenant's Pro Rata Share of Project Operating Expenses for
such calendar year were less than Tenant's obligation for the calendar year,
Tenant shall pay the deficiency to the Landlord within thirty (30) days after
delivery of such statement. All costs and expenses in connection with the
Independent Review shall be Tenant's sole obligation; provided, however, that
if the Independent Review shows that Tenant's payments of Tenant's Pro Rata
Share of Building Operating Expenses Tenant's Pro Rata Share of Project
Operating Expenses actually paid for the calendar year in question exceeded
Tenant's obligations for such calendar year by five percent (5%) or more,
Landlord shall pay the costs of the Independent Review.

         7.4. The responsibility of Tenant for Tenant's Pro Rata Share of
Building Operating Expenses and Tenant's Pro Rata Share of Project Operating
Expenses shall continue to the latest of (i) the date of termination of the
Lease, or (ii) the date Tenant has fully vacated the Demised Premises
(including, without limitation, the removal of all items required hereby to be
removed and the completion of all procedures necessary to fully release and
terminate any permits or licenses restricting the use of the Demised Premises
in any manner).

         7.5. Operating Expenses for the calendar year in which Tenant's
obligation to share therein commences and in the calendar year in which such
obligation ceases, shall be prorated. Expenses such as taxes, assessments and
insurance premiums which are incurred for an extended time period shall be
prorated based upon time periods to which applicable so that the amounts relate
to the time period wherein Tenant has an obligation to share in Operating
Expenses.

         7.6. [Intentionally Omitted.]

         7.7. The parties agree that statements in this Lease to the effect
that Landlord is to perform certain of its obligations hereunder at its own
cost and expense shall not be interpreted as excluding any cost from Operating
Expenses if such cost is an Operating Expense pursuant to the terms of this
Lease.

8.       Rentable and Usable Area


                                      10
<PAGE>   13


         8.1. The terms "Rentable Area" as used within this Lease shall mean
the rentable area and useable area, respectively, as calculated in accordance
with the 1996 Standard Method for Measuring Floor Area in Office Buildings as
adopted by the Building Owners and Managers Association.

9.       Security Deposit

         9.1. Tenant has deposited with Landlord the sum set forth in Section
2.1.8 (together with all interest earned thereon, the "Security Deposit") in
cash, which Security Deposit shall be held by Landlord as security for the
performance by Tenant of all of the terms, covenants, and conditions of this
Lease to be kept and performed by Tenant during the Term. If a Default occurs
with respect to any provision of this Lease, including, but not limited to, any
provision relating to the payment of Rent, Landlord may (but shall not be
required to) use, apply or retain all or any part of the Security Deposit for
the payment of any Rent or any other sum in Default, or to compensate Landlord
for any other loss or damage which Landlord may suffer by reason of Tenant's
Default. If any portion of the Security Deposit is so used or applied, Tenant
shall, upon demand therefor, deposit cash with Landlord in an amount sufficient
to restore the Security Deposit to its original amount, and Tenant's failure to
do so shall be a material breach of this Lease. The Security Deposit shall be
held in an interest bearing account separate from Landlord's general fund.

         9.2. In the event of bankruptcy or other debtor-creditor proceedings
against Tenant, the Security Deposit shall be deemed to be applied first to the
payment of Rent and other charges due Landlord for all periods prior to the
filing of such proceedings.

         9.3. Landlord shall deliver the Security Deposit, or any balance
thereof following application of any portion of the Security Deposit pursuant
to the provisions of Section 9.1, to any purchaser of Landlord's interest in
the Demised Premises, and, upon such purchaser's written confirmation of
receipt of the Security Deposit and assumption of Landlord's obligations under
this Lease, Landlord shall be discharged from any further liability with
respect to the Security Deposit. This provision shall also apply to any
subsequent transfers.

         9.4. If Tenant shall fully perform every provision of this Lease to be
performed by Tenant, the Security Deposit, or any balance thereof following
application of any portion of the Security Deposit pursuant to the provisions
of Section 9.1, shall be returned to Tenant (or, at Landlord's option, to the
last assignee of Tenant's interest hereunder) within thirty (30) days after the
expiration or earlier termination of this Lease.

research (and related uses) being conducted by Tenant or other occupants of the
Building as of the Effective Date, for purposes which Landlord reasonably finds
immoral or objectionable. Tenant shall not knowingly cause, maintain or permit
any nuisance or waste in, on, or about the Building or Project.

and expenses arising out of or in connection with the compliance with any

         11.2. Tenant hereby indemnifies and shall defend, hold and save

any representation or warranty relied upon by Tenant in Tenant's decision to
enter into this Lease other than as contained in this Lease.

         11.4. Tenant acknowledges and agrees that the employment of brokers by
Landlord is for the purpose of solicitation of offers of lease from prospective
tenants and no authority is granted to any broker to furnish any representation
(written or oral) or warranty from Landlord unless expressly contained within
this Lease. Landlord in executing this Lease does so in reliance upon Tenant's
representations and warranties contained within Sections 11.1 and 11.3 hereof.

12.      Holding Over

         12.1. If, with Landlord's express written consent, Tenant holds
possession of all or any part of the Demised Premises after the expiration or
earlier termination of the Term, Tenant shall become a tenant from
month-to-month upon the date of such expiration or earlier termination, and in
such case Tenant shall continue to pay Basic Annual Rent in the amount payable

                                      14
<PAGE>   17


such other amount as Landlord may indicate, in Landlord's sole and absolute
discretion, in such written consent, and all other provisions, representations,
covenants and agreements contained herein, other than with respect to the Term
and any extensions thereof, but specifically including, without limitation, the
adjustment of Basic Annual Rent pursuant to Section 6 hereof, shall remain in
full force and effect.

         12.2. Notwithstanding the foregoing, if Tenant remains in possession
of the Demised Premises after the expiration or earlier termination of the Term
without the express written consent of Landlord, Tenant shall become a tenant
at sufferance upon the terms of this Lease except that the monthly rental shall
be equal to one hundred fifty percent (150%) of the Basic Annual Rent and
Additional Rent in effect during the last thirty (30) days of the Term. Tenant
shall be responsible for all damages suffered by Landlord resulting from or
occasioned by Tenant's holding over.

         12.3. Acceptance by Landlord of Rent after such expiration or earlier
termination shall not result in a renewal or reinstatement of this Lease.

         12.4. The foregoing provisions of this Section 12 are in addition to
and do not affect Landlord's right to re-entry or any other rights of Landlord
hereunder or as otherwise provided by law.

13.      Taxes

         13.1. Tenant shall pay, prior to delinquency, any and all taxes levied
against any personal property or trade fixtures placed by Tenant in or about
the Demised Premises.

         13.2. If any such taxes on Tenant's personal property or trade
fixtures are levied against Landlord or Landlord's property or, if the assessed
valuation of the Building or the Project is increased by the inclusion therein
of a value attributable to Tenant's personal property or trade fixtures, and if
Landlord, after written notice to Tenant, pays the taxes based upon such
increase in the assessed value, then Tenant shall upon demand repay to Landlord
the taxes so levied against Landlord.

14.      Condition of Demised Premises

         14.1. Tenant acknowledges that neither Landlord nor any agent of
Landlord has made any representation or warranty with respect to the condition
of the Demised Premises or the Building or Project, or with respect to the
suitability for the conduct of Tenant's business. The taking of possession of
the Demised Premises by Tenant shall, except as otherwise agreed in writing by
Landlord and Tenant conclusively establish that the Demised Premises and
Building were at such time in good, sanitary and



                                      15
<PAGE>   18


satisfactory condition and repair. Tenant further acknowledges that Tenant is
accepting the Demised Premises "AS-IS," provided, however, that the foregoing
shall in no way limit Landlord's obligations under the Lease, including without
limitation, Landlord's obligations to perform Capital Repairs, maintenance and
repairs of the Project Common Areas and repairs, subsequent to any casualty or
condemnation as set forth herein.

15.      Parking Facilities

         15.1. As an appurtenance to the Demised Premises, Tenant shall have
the exclusive right on a reserved basis to use parking facilities serving the
Building located on the Land and depicted on the Site Plan as "Tenant's
Designated Spaces" (the "Parking Allotment").

         15.2. Tenant agrees not to unreasonably overburden the parking
facilities in excess of the Parking Allotment and agrees to cooperate with
Landlord and other tenants in the use of parking facilities. Landlord reserves
the right to determine that parking facilities are becoming overcrowded and to
limit Tenant's use thereof (but not below the Parking Allotment). Upon such
determination, Landlord may reasonably allocate parking spaces among Tenant and
other tenants; provided that Tenant shall at all times be allowed to use the
Parking Allotment. In the alternative, if Landlord determines that Tenant's
customers, clients, or invitees appear to be using more than the Parking
Allotment, Landlord may require Tenant and its employees to obtain parking
outside the Project for such excess uses. However, nothing in this Section 15.2
is intended to create an affirmative duty on Landlord's part to monitor
parking.

16.      Utilities and Services

         16.1. Tenant shall pay for all water, (including the cost to service,
repair and replace reverse osmosis, deionized and other treated water) gas,
heat, light, power, telephone and other utilities supplied to the Demised
Premises, together with any fees, surcharges and taxes thereon. All such
utilities shall be separately metered to Tenant.

         16.2. Landlord shall not be liable for, nor shall any eviction of
Tenant result from, the failure to furnish any such utility or service whether
or not such failure is caused by accident, breakage, repairs, strikes, lockouts
or other labor disturbances or labor disputes of any character, governmental
regulation, moratorium or other governmental action, inability despite the
exercise of reasonable diligence or by any other cause. In the event of such
failure, Tenant shall not be entitled to any abatement or reduction of Rent,
nor be relieved from the operation of any covenant or agreement of this Lease.


                                      16

         16.3. Tenant shall pay directly to the applicable utility or service
provider, prior to delinquency, for all utilities and services which may be
furnished to Tenant or the Demised Premises during the Term.

         16.4. If Tenant desires to use any device in the Demised Premises,
including, but without limitation, data processing machines and laboratory
equipment, which will in any way increase the amount of ventilation, air
exchange, gas, steam, electricity or water beyond the existing capacity of the
Building, Tenant shall be solely responsible for all cost and expense in
connection with increasing the existing capacity of the Building, and all
alterations required to so increase the capacity shall be made upon prior
written notice to Landlord and pursuant to the terms and provisions of Article
17.

         16.5. [Intentionally Omitted.]

         16.6. [Intentionally Omitted.]

         16.7. Landlord reserves the right to stop service of the elevator,
plumbing, ventilation, air conditioning and electric systems, when necessary,
by reason of accident or emergency or for repairs, alterations or improvements
(but only to the extent and for such time as reasonably necessary under the
circumstances), in the reasonable judgment of Landlord desirable or necessary
to be made, until said repairs, alterations or improvements shall have been
completed, and Landlord shall use its good faith efforts to cause such repairs,
alterations or improvements to be promptly completed. Landlord shall further
have no responsibility or liability for failure to supply elevator facilities,
plumbing, ventilation, air conditioning or electric service, when prevented
from doing so by strike or accident, or by laws, rules, order, ordinances,
directions, regulations or requirements of any federal, state, country or
municipal authority or failure to deliver gas, oil or other suitable fuel
supply or inability by exercise of reasonable diligence to obtain gas, oil or
other suitable fuel. It is expressly understood and agreed that any covenants
on Landlord's part to furnish any service pursuant to any of the terms,
covenants, conditions, provisions or agreements of this Lease, or to perform
any act or thing for the benefit of Tenant, shall not be deemed breached if
Landlord is unable to furnish or perform the same by virtue of a strike or
labor trouble or any other cause outside the reasonable control of Landlord.

17.      Alterations

         17.1. Tenant shall make no alterations, additions or improvements in
or to the Demised Premises without Landlord's prior written consent, which
approval shall not be unreasonably withheld, conditioned or delayed (provided,
however, that in the event any proposed alteration, addition or


                                      17
<PAGE>   20


improvement affects (i) any structural portions of the Building including
exterior walls, roof, foundation and core of the Building, (ii) the exterior of
the Building or (iii) any Building systems, including elevator, plumbing, air
conditioning, heating electrical, security, life safety and power, then
Landlord may withhold its consent with respect thereto in its sole and absolute

approval, Tenant shall provide Landlord, at least fourteen (14) days in advance
of any proposed construction, with plans, specifications, bid proposals, work
contracts and such other information concerning the nature and cost of the
alterations as may be reasonably requested by Landlord. Notwithstanding
anything contained herein to the contrary, to the extent Tenant desires to
alter the Demised Premises for the purpose of installing ventilation hoods and
ventilation systems, back-up generators or security systems, Landlord shall
grant or withhold its consent in the exercise of its reasonable discretion and
such consent shall not be unreasonably conditioned or delayed. Further,
alterations to the Demised Premises having a cost of $25,000 or less which are
not referenced in the previous sentence or described in items (i) (ii) or (iii)
of this Section 17.1 may be made by Tenant without Landlord's consent or
approval; provided, however, Tenant shall provide Landlord with prior written
notice describing in reasonable detail the alterations being undertaken by
Tenant without Landlord's consent.

         17.2. [Intentionally Omitted.]

         17.3. Tenant agrees that there shall be no construction of partitions
or other obstructions which might interfere with free access to mechanical

         17.4. Tenant agrees that any work by Tenant shall be accomplished in
such a manner as to permit any fire sprinkler system and fire water supply

         17.5. Tenant covenants and agrees that all work done by Tenant shall
be performed in full compliance with all laws, rules, orders, ordinances,
directions, regulations, and requirements of all governmental agencies,
offices, departments, bureaus and boards having jurisdiction, and in full
compliance with the rules, orders, directions, regulations, and requirements of
any applicable fire rating bureau. Upon demand by Landlord, Tenant shall
provide Landlord with (i) construction agreements, building plans, lien
releases and other similar documentation with respect to any improvements or
alterations reasonably requested by Landlord or Landlord's lenders, insurers or
investors, and (ii) "as-built" plans showing any change in the Demised
Premises.

         17.6. Before commencing any work, Tenant shall give Landlord at least
fourteen (14) days prior written notice of the proposed commencement of such
work and shall, for any work costing in excess of One Hundred Thousand Dollars
($100,000) and if required by Landlord, secure at Tenant's own cost and expense
a completion and lien indemnity bond or other security for completion of said
work reasonably satisfactory to Landlord.

         17.7. All alterations, attached equipment, decorations, fixtures,
trade fixtures, additions and improvements, built-in furniture and cabinets,
together with all additions and accessories thereto, subject to Sections 17.9
and 17.10, attached to or built into the Demised Premises, made by either of

climatized rooms, ductwork, conduits, electrical panels and circuits, shall
become the property of Landlord upon the expiration or earlier termination of
the term of this Lease, and shall remain upon and be surrendered with the
Demised Premises as a part thereof. At the same time as Landlord delivers to
Tenant Landlord's consent to any alteration, addition or improvement pursuant
to Section 17.1, Landlord shall notify Tenant of Landlord's election to cause
Tenant to remove any items which are the subject of such consent from the
Demised Premises upon the expiration or earlier termination of this Lease, and,
if Landlord so elects, Tenant shall remove such alterations, attached
equipment, decorations, fixtures, trade fixtures, additions and improvements
upon the expiration or earlier termination of this Lease and restore any damage
caused by or occasioned as a result of such result. Tenant shall be deemed to

equipment, built-in furniture and cabinets, together with all additions and
accessories thereto, installed in and upon the Demised Premises as of the
Effective Date shall be and remain the property of Landlord and shall not be
moved by Tenant at any time during the Term. If Tenant shall fail to remove all
of its property from the Demised Premises prior to expiration or earlier
termination of this Lease, then Landlord may, at its option, remove the same in
any manner that Landlord shall choose, and store said effects without liability
to Tenant for loss thereof or damage thereto, and Tenant agrees to pay Landlord
upon demand any expenses incurred by Landlord in connection with such removal
and storage or Landlord may, subject to applicable law, at its option, without
notice, sell said property or any of the same, at private sale and without
legal process, for such price as Landlord may obtain


                                      19
<PAGE>   22

and apply the proceeds of such sale against any amounts due under this Lease
from Tenant to Landlord and against any expenses incident to the removal,
storage and sale of said personal property.

         17.10. Notwithstanding any other provision of this Section 17 to the
contrary, in no event may Tenant remove any improvement from the Demised
Premises as to which Landlord contributed payment without Landlord's prior
written consent, which may be withheld in Landlord's sole discretion.

         17.11. In connection with any improvement or alteration project
costing in excess of Twenty-Five Thousand ($25,000), Tenant shall pay to
Landlord up to five percent (5%) of the cost to Tenant of all charges incurred
by Tenant of its contractors or agents in connection with such alterations,
additions or improvements to the Demised Premises to cover Landlord's actual
expenses for plan review, coordination, scheduling and supervision thereof. For
purposes of payment of such sum, Tenant shall submit to Landlord copies of all
bills, invoices, and statements covering the costs of such charges, which will
be accompanied by payment to Landlord of the percentage fee set forth above.
Tenant shall reimburse Landlord for any extra expense incurred by Landlord by
reason of faulty work done by Tenant or its contractors, or by reason of delays
caused by such work, or by reason of inadequate cleanup.

18.      Repairs and Maintenance

         18.1. Landlord shall perform the Capital Repairs and shall repair and
maintain the Project Common Areas, including, without limitation, repair and
maintenance of landscaping, parking facilities, driveways, walkways, lighting,
utilities, snow removal, irrigation and storm water management systems (and the
full or amortized cost thereof, as applicable, shall be included as a part of
Operating Expenses), unless such Capital Repairs or maintenance or repairs are
required in whole or in part because of any act, neglect, fault of or omissions
of any duty by Tenant, its agents, servants, employees, contractors, guests or
invitees, in which case Tenant shall pay to Landlord the cost of such Capital
Repairs or maintenance and repairs to the extent such costs are incurred as a
result of any act, neglect, fault of or omission of any duty by Tenant, its
agents, servants, employees, contractors, guests or invitees.

         18.2. Except for services of Landlord, if any, required by Section
18.1, Tenant shall at Tenant's sole cost and expense keep the Demised Premises
and every part thereof in good condition and repair, damage thereto from
ordinary wear and tear excepted and subject to the provisions of Section 22.

surrender the Demised Premises to Landlord in as good as condition


                                      20
<PAGE>   23


as when received, ordinary wear and tear excepted and subject to the provisions

ordinary course of operation of the Building, the Project and any related

provisions of Section 22 shall apply and control.

19.      Liens

         19.1. Subject to the immediately succeeding sentence, Tenant shall
keep the Demised Premises, the Building, and the Land free from any liens
arising out of work performed, materials furnished or obligations incurred by
Tenant. Tenant further covenants and agrees that any mechanic's lien filed
against the Demised Premises or against the Building or the Project for work
claimed to have been done for, or materials claimed to have been furnished to
Tenant, will be discharged by Tenant, by bond or otherwise, within thirty (30)
days after the receipt of notice of the filing thereof, at the sole cost and
expense of Tenant.

         19.2. Should Tenant fail to discharge any lien of the nature described
in Section 19.1, Landlord may at Landlord's election pay such claim or post a
bond or otherwise provide security to eliminate the lien as a claim against
title and the cost thereof shall be immediately due from Tenant as Additional
Rent.

         19.3. In the event Tenant shall lease or finance the acquisition of
office equipment, furnishings, or other personal property of a removable nature
utilized by Tenant in the operation of Tenant's business, Tenant warrants that
any Uniform Commercial Code Financing Statement executed by Tenant will upon
its face or by exhibit thereto indicate that such Financing Statement is
applicable only to removable personal property of Tenant located within the
Demised Premises. In no event shall the address of the Building be furnished on
the statement without qualifying language as to applicability of the lien only
to removable personal property owned by Tenant, located in an identified suite
held by Tenant. Should any holder of a Financing Statement executed by Tenant
record or place of record a Financing Statement which appears to constitute a
lien against any interest of Landlord or against equipment which may be located
other than within the Demised Premises, Tenant shall within ten (10) days after
filing such


                                      21
<PAGE>   24

Financing Statement (i) cause a copy of the Security Agreement or other
documents to which Financing Statement pertains to be furnished to Landlord to
facilitate Landlord's being in a position to show such lien is not applicable
to Landlord's interest, and (ii) cause Tenant's lender to amend any documents
of record so as to clarify that such lien is not applicable to any interest of
Landlord in the Building or the Project.

20.      Indemnification and Exculpation

         20.1. Tenant hereby indemnifies and agrees to defend and save Landlord
harmless from and against any and all demands, claims, liabilities, losses,
costs, expenses, actions, causes of action, damages or judgments, and all
reasonable expenses actually incurred in investigating or resisting the same
(including, without limitation, reasonable attorneys' fees, charges and
disbursements actually incurred), for injury or death to person or injury to
property occurring within or about Project, arising out of Tenant's, it's
employees, agents or guests use or occupancy of the Project or a breach or
default by Tenant in the performance of any of its obligations hereunder,
except to the extent caused by the willful act or gross negligence of the
Landlord.

         20.2. Landlord hereby indemnifies and agrees to defend, hold and save
Tenant harmless from and against any and all demands, claims, liabilities,
losses, costs, expenses, actions, causes of action, damages or judgments, and

disbursements actually incurred), for injury or death to person or injury to
property occurring within or about the Project, arising out of the use or
occupancy of the Project by Landlord and its employees, agents, or guests or a
breach or default by Landlord in the performance of any of its obligations
hereunder, except to the extent caused by the willful act or gross negligence
of Tenant.

         20.3. Landlord shall not be liable to Tenant and Tenant assumes all
risk of damage to personal property or scientific research, including loss of
records kept within the Demised Premises if the cause of such damage is of a
nature which, if Tenant had elected to maintain fire and theft insurance with
extended coverage and business records endorsement available on a commercially
reasonable basis, would be a loss subject to settlement by the insurance
carrier, including, but not limited to, damage or losses caused by fire,
electrical malfunctions, gas explosion, and water damage of any type,
including, but not limited to, broken water lines, malfunction of fire
sprinkler system, roof leakage or stoppages of lines unless and except if such
loss is due to willful disregard of Landlord after written notice by Tenant of
need for a repair which Landlord is responsible to make for an unreasonable
period of time. Tenant further waives any claim for injury to Tenant's business
or loss


                                      22
<PAGE>   25


of income relating to any such damage or destruction of personal property
including any loss of records.

         20.4. Landlord shall not be liable for any damages arising from any
act, omission or neglect of any other tenant in the Building or the Project or
of any other unrelated third party, except to the extent caused by the willful
act or gross negligence of Landlord or any of its employees, agents or
independent contractors.

         20.5. Security devices and services, if any, while intended to deter
crime may not in given instances prevent theft or other criminal acts and it is
agreed that Landlord shall not be liable for injuries or losses caused by
criminal acts of third parties and the risk that any security device or service
may malfunction or otherwise be circumvented by a criminal is assumed by
Tenant. Tenant shall at Tenant's cost obtain insurance coverage to the extent
Tenant desires protection against such criminal acts.

21.      Insurance - Waiver of Subrogation

         21.1. Landlord, as part of Operating Expenses, shall carry throughout
the Term insurance upon the Building, (i) in an amount equal to full
replacement cost (exclusive of the costs of excavation, foundations, and
footings, and without reference to depreciation taken by Landlord upon its
books or tax returns), (ii) providing protection against any peril generally
included within the classification "Fire and Extended Coverage" together with
insurance against sprinkler damage (if applicable), vandalism and malicious
mischief and rental losses for a period not less than twelve (12) months, and
(iii) if commercially available, with a deductible not to exceed Ten Thousand
Dollars ($10,000). At Tenant's request, Landlord shall use its good faith
efforts to cause such deductible to be reduced, provided that such reduced
deductible is commercially available and that Tenant shall be solely
responsible for all costs and expenses in connection with the reduction of such
deductible, including, without limitation, any increases in the premium
associated with such reduced deductible. Landlord, subject to availability
thereof and, as part of Operating Expenses, shall further insure as Landlord
deems appropriate coverage against flood, environmental hazard and earthquake,
loss or failure of building equipment, rental loss during the period of repair
or rebuild, workmen's compensation insurance and fidelity bonds for employees
employed to perform services. Notwithstanding the foregoing, Landlord may, but
shall not be deemed required to, provide insurance as to any improvements
installed by Tenant or which are in addition to the standard improvements
customarily furnished by Landlord without regard to whether or not such are
made a part of the Building.

         21.2. Landlord, as part of Operating Expenses, shall further carry
throughout the Term commercial general liability insurance with a single loss


                                      23
<PAGE>   26


limit of not less than Two Million Dollars ($2,000,000.00) for death or bodily
injury, or property damage with respect to the Project.

         21.3. Tenant at its own cost shall procure and continue in effect from
the Term Commencement Date and continuing throughout the Term (and occupancy by
Tenant, if any, after the expiration or earlier termination of this Lease)
comprehensive commercial liability insurance with limits of not less than Two
Million Dollars ($2,000,000.00) per occurrence for death or bodily injury, not
less than One Million Dollars ($1,000,000.00) for property damage with respect
to the Demised Premises, and not less than a Five Million Dollar ($5,000,000)
aggregate loss limit.

         21.4. The aforesaid required insurance shall name Landlord and Tenant,
and their respective officers, employees and agents, as insureds. All insurance
required by this Article 21 shall be with companies having a rating of not less
than policyholder rating of A and financial category rating of at least Class
XII in "Best's Insurance Guide." Each of Landlord and Tenant shall obtain from
its insurance companies or cause its insurance companies to furnish
certificates of coverage to the other party hereto. No such policy shall be
cancelable or subject to reduction of coverage or other modification or
cancellation except after thirty (30) days prior written notice to Landlord
from the insurer. All such policies shall be written as primary policies, not
contributing with and not in excess of the coverage which Landlord may carry.
Tenant's policy may be a "blanket policy" which specifically provides that the
amount of insurance shall not be prejudiced by other losses covered by the
policy. Each of Landlord and Tenant shall, at least twenty (20) days prior to
the expiration of such policies, furnish the other party hereto with renewals
or binders. Tenant agrees that if Tenant does not take out and maintain such
insurance, Landlord may (but shall not be required to) procure said insurance
on Tenant's behalf and at its cost to be paid as Additional Rent.

         21.5. Tenant assumes the risk of damage to any fixtures, goods,
inventory, merchandise, equipment, and leasehold improvements, and Landlord
shall not be liable for injury to Tenant's business or any loss of income
therefrom relative to such damage all as more particularly heretofore set forth
within this Lease. Tenant at Tenant's cost shall carry such insurance as Tenant
desires for Tenant's protection with respect to personal property of Tenant or
business interruption.

         21.6. The party carrying the insurance required hereunder shall upon
written request of the other party hereto, also designate and furnish
certificates evidencing the requesting party as an insured to (i) any lender of
such requesting party holding a security interest in, as applicable, the Lease
or the Building or real property upon which the Building is situated, and/or
(ii) the landlord under any lease wherein Landlord is tenant of the real
property


                                      24
<PAGE>   27



whereupon the Building is located if the interest of Landlord is or shall
become that of a tenant under a ground lease rather than that of a fee owner,
and/or (iii) any management company retained by Landlord to manage the Project.

         21.7. Landlord and Tenant each hereby waive any and all rights of
recovery against the other or against the officers, directors, employees,
agents, and representatives of the other, on account of loss or damage
occasioned to such waiving party or its property or the property of others
under its control to the extent that such loss or damage is insured against
under any fire and extended coverage insurance policy which either may have in
force, but not less than as required pursuant to this Article 21, at the time
of such loss or damage. Such waivers shall continue as long as their respective
insurers so permit. Any termination of such a waiver shall be by written notice
of circumstances as hereinafter set forth. Landlord and Tenant upon obtaining
the policies of insurance required or permitted under this Lease shall give
notice to the insurance carrier or carriers that the foregoing mutual waiver of
subrogation is contained in this Lease. If such policies shall not be
obtainable with such waiver or shall be so obtainable only at a premium over
that chargeable without such waiver, the party seeking such policy shall notify
the other thereof, and the latter shall have ten (10) days thereafter to either
(i) procure such insurance with companies reasonably satisfactory to the other
party or (ii) agree to pay such additional premium. If neither (i) nor (ii) are
done, this Section 21.7 shall have no effect during such time as such policies
shall not be obtainable or the party in whose favor a waiver of subrogation is
desired refuses to pay the additional premium. If such policies shall at any
time be unobtainable, but shall be subsequently obtainable, neither party shall
be subsequently liable for a failure to obtain such insurance until a
reasonable time after notification thereof by the other party. If the release
of either Landlord or Tenant, as set forth in the first sentence of this
Section 21.7 shall contravene any law with respect to exculpatory agreements,
the liability of the party in question shall be deemed not released but shall
be secondary to the other's insurer.

         21.8. Landlord may require insurance policy limits to be raised to
conform with requirements of Landlord's lender.

22.      Damage or Destruction

         22.1. In the event of a partial destruction of the Building (i) by
fire or other perils covered by extended coverage insurance required by Section
21 not exceeding (x) twenty-five percent (25%) of the full insurable value
thereof, or (y) so long at least five (5) years will remain in the Term (as the
Term may have been extended pursuant to Section 41 hereof) as of the date of
completion of reconstruction, fifty percent (50%) of the full insurable value
thereof; (ii) the damage thereto is such that the Building may be repaired,


                                      25
<PAGE>   28

reconstructed, or restored within a period of nine (9) months from the date of
the happening of such casualty; and (iii) Landlord will receive insurance
proceeds sufficient to cover the cost of such repairs (except for any
deductible amount provided by Landlord's policy pursuant to the terms of
Section 21, which deductible amount if paid by Landlord shall be an Operating
Expense), Landlord shall commence and proceed diligently with the work of
repair, reconstruction and restoration and this Lease shall continue in full
force and effect.

         22.2. In the event of any damage to or destruction of the Building,
other than as provided in Section 22.1, Landlord may elect to repair,
reconstruct and restore the Building, in which case this Lease shall continue
in full force and effect. If Landlord elects not to repair then this Lease
shall terminate as of date of destruction.

         22.3. Landlord shall give written notice to Tenant of its election not
to repair, reconstruct or restore the Building or Project within the sixty (60)
day period following the date of damage or destruction.

         22.4. Upon any termination of this Lease under any of the provisions
of this Section, the parties shall be released thereby without further
obligation to the other from the date possession of the Demised Premises is
surrendered to the Landlord except for obligations which have theretofore
accrued.

         22.5. In the event of repair, reconstruction and restoration as herein
provided, the rental provided to be paid under this Lease shall be abated
proportionately based on the extent to which Tenant's use of the Demised
Premises is impaired during the period of such repair, reconstruction or
restoration, unless Landlord provides Tenant with other space during the period
of repair, which in Tenant's reasonable opinion is suitable for the temporary
conduct of Tenant's business.

         22.6. Notwithstanding anything to the contrary contained in this
Section, should Landlord be delayed or prevented from completing the repair or
restoration of the damage to the Demised Premises after the occurrence of such
damage or destruction by reason of acts of God or war, governmental
restrictions, inability to procure the necessary labor or materials, strikes,
or other reasons beyond the control of Landlord (collectively, "Force Majeure
Delay"), the time for Landlord to commence or complete repairs shall be
extended; provided, at the election of either party exercisable by the delivery
of written notice to the other party not later than sixty (60) days after
Landlord notifies Tenant of Landlord's inability to complete the repairs by the
end of the eighteenth (18th) month following such damage as a result of a
Force-Majeure Delay, Landlord shall be


                                      26
<PAGE>   29


relieved of its obligation to make such repairs or restoration and Tenant shall
be released from its obligation under this Lease effective as of the date of
the receipt of such written notice.

         22.7. If Landlord is obligated to or elects to repair or restore as
herein provided, Landlord shall be obligated to make repairs or restoration
only of those portions of the Building and the Demised Premises which were
originally provided at Landlord's expense; the repair and restoration of items
not provided at Landlord's expense shall be the obligation of Tenant. In the
event Tenant elected to upgrade certain improvements from the standard normally
provided by Landlord, Landlord shall, upon the need for replacement due to an
insured loss, provide only the standard Landlord improvements unless Tenant
shall elect to again upgrade and pay any additional cost of such upgrades,
except to such extent as insurance proceeds which, if received, the excess
proceeds are adequate to provide such upgrades, in addition to providing for
basic reconstruction and standard improvements.

         22.8. Notwithstanding anything to the contrary contained in this
Section, Landlord shall not have any obligation whatsoever to repair,
reconstruct or restore the Demised Premises when the damage resulting from any
casualty covered under this Section exceeds Fifty Thousand Dollars ($50,000)
and occurs during the last twenty-four (24) months of the Term (as the Term may
have been extended pursuant to Section 41 hereof), or to the extent that
insurance proceeds are not available therefor; provided, however, that if
Landlord elects not to repair, reconstruct or restore under this Section 22.8
Tenant may cause Landlord to repair, reconstruct or restore (so long as, and to
the extent that, insurance proceeds are available) by exercising its right to
extend the Term of the Lease within fifteen (15) days of Landlord's notice to
Tenant of Landlord's election not to repair pursuant to this Section 2.8. If
Landlord elects not to repair then this Lease shall terminate as of date of
destruction.

23.      Eminent Domain

         23.1. In the event the whole of the Demised Premises, or such part
thereof as shall substantially interfere with the Tenant's use and occupancy
thereof, shall be taken for any public or quasi-public purpose by any lawful
power or authority by exercise of the right of appropriation, condemnation or
eminent domain, or sold to prevent such taking, Tenant or Landlord may
terminate this Lease effective as of the date possession is required to be
surrendered to said authority.

         23.2. In the event of a partial taking of the Building or the Land for
any public or quasi-public purpose by any lawful power or authority by exercise
of right of appropriation, condemnation, or eminent domain, or sold


                                      27
<PAGE>   30

to prevent such taking, then Landlord may elect to terminate this Lease as of
such taking if such taking is, in the opinion of Landlord, of a material nature
such as to make it uneconomical to continue use of the unappropriated portion
for the purposes contemplated by this Lease.

         23.3. Tenant shall be entitled to any award which is specifically
awarded as compensation for the taking of Tenant's property, which was
installed at Tenant's expense and for costs of Tenant moving to a new location.
Except as before set forth, any award for such taking shall belong to Landlord;
provided, that, Tenant shall have the right, at Tenant's sole cost and expense,
to pursue a separate award from the condemning authority in connection with
such taking and Tenant hereby indemnifies and agrees to defend and save
Landlord harmless from and against any and all demands, claims, liabilities,
losses, costs, expenses, actions, causes of action, damages or judgments, and
all reasonable expenses actually incurred (including, without limitation,
reasonable attorneys' fees, charges and disbursements actually incurred)
arising out of or in connection with Tenant's pursuit of such separate award,
including, without limitation, any reduction in the award granted to Landlord.

         23.4. If, upon any taking of the nature described in this Section 23,
this Lease continues in effect, the Landlord shall promptly proceed to restore
the Demised Premises, Building and the Project to substantially their same
condition prior to such partial taking. To the extent such restoration is
feasible, as determined by Landlord in its sole discretion, the Rent shall be
abated proportionately based upon the extent to which Tenant's use of the
Demised Premises has decreased on the basis of the percentage of the rental
value of the Demised Premises after such taking and the rental value of the
Demised Premises prior to such taking.

24.      Defaults and Remedies

         24.1. If Tenant is in Default of Tenant's obligation to pay Rent,
Tenant shall pay to Landlord an additional sum of six percent (6%) of the
overdue Rent as a late charge. In addition to the late charge if Tenant is in
Default of Tenant's obligation to pay Rent. Rent not paid when due shall bear
interest from the 5th day after date due until paid at the lesser of (i) twelve
percent (12%) per annum or (ii) the maximum rate permitted by law.

         24.2. No payment by Tenant or receipt by Landlord of a lesser amount
than the Rent payment herein stipulated shall be deemed to be other than on
account of the Rent, nor shall any endorsement or statement on any check or any
letter accompanying any check or payment as Rent be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice
to Landlord's right to recover the balance of such Rent or pursue any other
remedy provided. If at any time a dispute shall arise as to


                                      28
<PAGE>   31

any amount or sum of money to be paid by Tenant to Landlord, Tenant shall have
the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment, and there shall survive the right on the part
of Tenant to institute suit for recovery of the payment paid under protest.

         24.3. If Tenant fails to pay any sum of money required to be paid by
it hereunder, or shall fail to perform any other act on its part to be
performed hereunder, Landlord may, without waiving or releasing Tenant from any
obligations of Tenant, but shall not be obligated to, make such payment or
perform such act. All sums so paid or incurred by Landlord, together with
interest thereon, from the date such sums were paid or incurred, at the annual
rate equal to twelve percent (12%) per annum or highest rate permitted by law,
whichever is less, shall be payable to Landlord on demand as Additional Rent.

         24.4. The occurrence of any one or more of the following events shall
constitute a "Default" hereunder by Tenant:

               24.4.1 The abandonment or vacation of the Demised Premises by
Tenant;

               24.4.2 The failure by Tenant to make any payment of Rent as and
when due and such failure continues for more than five (5) days following
delivery of written notice from Landlord (provided, however, that (i) no such
notice shall be required in the event that Landlord has given one (1) such
notice to Tenant within the preceding twelve (12) months, and (ii) such notice
shall be in place of, and not in addition to, any similar notice required under
Georgia law);;

               24.4.3 The failure by Tenant to observe or perform any
obligation or covenant contained herein (other than described in Section 24.4.1
and 24.4.2) to be performed by Tenant, where such failure shall continue for a
period of thirty (30) days after written notice thereof from Landlord to
Tenant. Such notice shall be in lieu of, and not in addition to, any notice
required under Georgia law; provided that if the nature of Tenant's default is
such that it reasonably requires more than thirty (30) days to cure, then
Tenant shall not be deemed to be in default if Tenant shall commence such cure
within said thirty (30) day period and thereafter diligently prosecutes the
same to completion provided, however, that such cure is completed no later than
ninety (90) days from the date of written notice;

               24.4.4 Tenant makes an assignment for the benefit of creditors;

               24.4.5 A receiver, trustee or custodian is appointed to, or
does, take title, possession or control of all, or substantially all, of
Tenant's assets and is not judicially dismissed within sixty (60) days after
appointment;


                                      29
<PAGE>   32


                  24.4.6 Tenant files a voluntary petition under the Bankruptcy
Code (or any similar law) or an order for relief is entered against Tenant
pursuant to a voluntary or involuntary proceeding commenced under any chapter
of the Bankruptcy Code;

                  24.4.7 Any involuntary petition if filed against the Tenant
under any chapter of the Bankruptcy Code and is not dismissed within ninety
(90) days; or

                  24.4.8 Tenant's interest in this Lease is attached, executed
upon, or otherwise judicially seized and such action is not released within
ninety (90) days of the action. Notices given under this Section 24.4 shall
specify the alleged default and shall demand that Tenant perform the provisions
of this Lease or pay the Rent that is in arrears, as the case may be, within
the applicable period of time, or quit the Demised Premises. No such notice
shall be deemed a forfeiture or a termination of this Lease unless Landlord
elects otherwise in such notice. Notwithstanding anything to the contrary set
forth herein, any Default relating to the payment of money shall be deemed
cured upon receipt by Landlord of the original amount payable by Tenant,
together will all late charges and interest due and owing on such original
amount as of the date of delivery of such original amount to Landlord.

         24.5. In the event of a Default by Tenant, and at any time thereafter,
with or without notice or demand and without limiting Landlord in the exercise
of any right or remedy which Landlord may have, Landlord shall be entitled to
terminate Tenant's right to possession of the Demised Premises by any lawful
means, in which case this Lease shall terminate and Tenant shall immediately
surrender possession of the Demised Premises to Landlord. In such event,
Landlord shall have the immediate right to re-enter and remove all persons and
property, and such property may be removed and stored in a public warehouse or
elsewhere at the cost of, and for the account of Tenant, all without service of
notice or resort to legal process and without being deemed guilty of trespass,
or becoming liable for any loss or damage which may be occasioned thereby. In
the event that Landlord shall elect to so terminate this Lease, then Landlord
shall be entitled to recover from Tenant all damages incurred by Landlord by
reason of Tenant's Default, including:

               24.5.1 The worth at the time of award of any unpaid Rent which
had been earned at the time of such termination; plus

               24.5.2 The worth at the time of award of the amount by which the
unpaid Rent which would have been earned after termination for the balance of
the term exceeds the reasonable rental value of the Demised Premises for such
time period; plus


                                      30
<PAGE>   33



               24.5.3 Any other amount necessary to compensate Landlord for all
the detriment proximately caused by Tenant's failure to perform its obligation
under this Lease or which in the ordinary course of things would be likely to
result therefrom, including, but not limited to, the cost of restoring the
Demised Premises to the condition required under the terms of this Lease; plus

               24.5.4 At the Landlord's election, such other amounts in
addition to or in lieu of the foregoing as may be permitted from time to time
by applicable law.

As used in Sections 24.5.1 above, "worth at the time of award" shall be
computed by allowing interest at the rate specified in Section 24.1. As used in
Section 24.5.2 above, the "worth at the time of the award" shall be computed by
taking the present value of such amount, by using the discount rate of the
Federal Reserve Bank of San Francisco at the time of the award plus six (6)
percentage points.

         24.6. If Landlord does not elect to terminate this Lease as provided
in this Section, then Landlord may, from time to time, recover all Rent as it
becomes due under this Lease. At any time thereafter, Landlord may elect to
terminate this Lease and to recover damage to which Landlord is entitled.

         24.7. In the event Landlord elects to terminate this Lease and relet
the Demised Premises, it may execute any new lease in its own name. Tenant
hereunder shall have no right or authority whatsoever to collect any Rent from
such tenant. The proceeds of any such reletting shall be applied as follows:

                  First, to the payment of any indebtedness other than Rent due
         hereunder from Tenant to Landlord, including, but not limited to,
         storage charges or brokerage commissions owing from Tenant to Landlord
         as the result of such reletting;

                  Second, to the payment of the costs and expenses of reletting
         the Demised Premises, including alterations and repairs which Landlord
         deems reasonably necessary and advisable and reasonable attorneys'
         fees, charges and disbursements actually incurred by Landlord in
         connection with the retaking of the Demised Premises and such
         reletting;

                  Third, to the payment of Rent and other charges due and
         unpaid hereunder; and

                  Fourth, to the payment of future Rent and other damages

                                      31
<PAGE>   34


         payable by Tenant under this Lease.

         24.8.  All rights, options, and remedies of Landlord contained in this
Lease shall be construed and held to be nonexclusive and cumulative. Landlord
shall have the right to pursue any one or all of such remedies or any other
remedy or relief which may be provided by law, whether or not stated in this
Lease. No waiver of any default of Tenant hereunder shall be implied from any
acceptance by Landlord of any Rent or other payments due hereunder or any
omission by Landlord to take any action on account of such default if such
default persists or is repeated, and no express waiver shall affect defaults
other than as specified in said waiver.

         24.9.  Termination of this Lease or Tenant's right to possession by
Landlord shall not relieve Tenant from any liability to Landlord which has
theretofore accrued or shall arise based upon events which occurred prior to
the last to occur of (i) the date of Lease termination or (ii) the date
possession of Demised Premises is surrendered.

         24.10. Landlord shall not be in default under any provision of this
Lease unless Landlord fails to perform obligations required of Landlord within
a reasonable time, but in no event shall such failure continue for more than
thirty (30) days after written notice by Tenant specifying wherein Landlord has
failed to perform such obligation; provided, however, that if the nature of
Landlord's obligation is such that more than thirty (30) days are required for
performance, then Landlord shall not be in default if Landlord commences
performance within such thirty (30) day period and thereafter diligently
prosecutes the same to completion. In the event that Landlord fails to cure any
default within the time periods set forth in this Section 24.10, or in the
event of a condition giving rise to an emergency threatening imminent harm to
human health or safety or substantial damage to property, Tenant shall have the
right to take all necessary and reasonable action to cure such default or
remedy such condition to the extent necessary to eliminate the emergency, and
all such action shall be performed by Tenant is a good and workmanlike manner
in accordance will all applicable governmental requirements. Upon delivery to
Landlord of documentation of the costs and expenses incurred by Tenant pursuant
to the provisions of this Section 24.10, which costs and expenses shall be at
the market rate regardless of whether Tenant performs the work or hires
unrelated third parties and shall not exceed the amounts necessary to cure the
specific default or emergency condition, Landlord shall reimburse Tenant for
such documented costs and expenses.

         24.11. In the event of any default on the part of Landlord, Tenant
will give notice by registered or certified mail to any beneficiary of a deed
of trust or mortgagee or a mortgage covering the Demised Premises and to any
landlord of any lease of any building in which Demised Premises is located
whose address shall have been furnished, and Tenant shall offer such
beneficiary, mortgagee


                                      32
<PAGE>   35


and/or landlord a reasonable opportunity to cure the default, including time to
obtain possession of the Building by power of sale or a judicial action if such
should prove necessary to effect a cure, provided the Landlord shall have
furnished to Tenant in writing the names and addresses of all such persons who
are to receive such notices.

25.      Assignment or Subletting

         25.1. Assignment. Tenant shall not, either voluntarily or by operation
of law, directly or indirectly, sell, hypothecate, assign, pledge, encumber or
otherwise transfer this Lease, without the prior written consent of Landlord in
each instance, which consent may be withheld in Landlord's sole discretion.

         25.2. Subleasing. Except as hereinafter provided, Tenant shall not,
either voluntarily or by operation of law, directly or indirectly, sublet the
Demised Premises or any part thereof, or permit or suffer the Demised Premises
or any part thereof to be used or occupied as work space, storage space,
mailing privileges, concession or otherwise by anyone other than Tenant or
Tenant's employees, without the prior written consent of Landlord in each
instance, which consent shall not be unreasonably withheld conditioned or
delayed. Landlord shall consent to the subleases of portions of the Demised
Premises to CytRx Corporation or its affiliates which are in compliance with
the terms of Section 25.7. 10 and are for a period not to exceed two (2) years
from the date hereof.

         25.3. If Tenant is a corporation, the shares of which are not actively
traded upon a stock exchange or in the over-the-counter market, a transfer or
series of transfers whereby twenty-five percent (25%) or more of the issued and
outstanding shares of such corporation are, or the voting control is,
transferred (but excepting transfers upon deaths of individual shareholders)
from a person or persons or entity or entities which were owners thereof at
time of execution of this Lease to persons or entities who were not owners of
shares of the corporation at time of execution of this Lease shall be deemed an
assignment of this Lease requiring the consent of Landlord as provided in
Section 25.1 above.

         25.4. If Tenant desires to assign this Lease to any entity into which
Tenant is merged, with which Tenant is consolidated, or which acquires all or
substantially all of the assets of Tenant, provided that the assignee first
executes, acknowledges and delivers to Landlord an agreement whereby the
assignee agrees to be bound by all of the covenants and agreements in this
Lease and that the assignee shall have a net worth (determined in accordance
with generally accepted accounting principles consistently applied) immediately
after such assignment which is at least equal to the net worth (as so
determined) of Tenant immediately prior to the assignment (or as of the date
hereof, if greater), then Landlord, upon receipt of proof of foregoing shall
consent to such assignment so long as no change in the permitted use pursuant
to Section 2 is requested.

         25.5. In the event Tenant desires to assign, sublease, hypothecate or
otherwise transfer this Lease or sublet the Demised Premises, then at least
thirty (30) days, but not more than ninety (90) days, prior to the date when
Tenant desires the assignment or sublease to be effective (the "Assignment
Date"), Tenant shall give Landlord a notice (the "Assignment Notice")
containing information (including references) concerning the character of the
proposed assignee or sublessee, the Assignment Date, any ownership or
commercial relationship between Tenant and the proposed assignee or sublessee,
and the consideration and all other material terms and conditions of the
proposed assignment or sublease along with such other information as Landlord
may reasonably require, all in such detail as Landlord shall reasonably
require.

         25.6. Landlord in making its determination as to whether consent
should be given to a proposed assignment or sublease, may give consideration to
the financial strength of such successor (notwithstanding the assignor
remaining liable for Tenant's performance) and any change in use which such
successor proposes to make in use of Demised Premises. In no event shall
Landlord be deemed to be unreasonable for declining to consent to transfer to a
successor of poor reputation, lacking financial qualifications, or seeking
change in use.

         25.7. As conditions precedent to Landlord considering a request by
Tenant to Tenant's transfer of rights or subletting of the Demises Premises,
Landlord may require any or all of the following:

               25.7.1 Tenant shall remain fully liable under this Lease during
the unexpired Term;

               25.7.2 Tenant shall provide Landlord with evidence reasonably
satisfactory to Landlord that the value of Landlord's interest under this Lease
will not thereby be diminished or reduced. Such evidence shall include, but
need not be limited to, evidence respecting the relevant business experience
and financial responsibility and status of the third party concerned;

               25.7.3 Tenant shall reimburse Landlord for Landlord's actual and
reasonable costs and expenses not to exceed Two Thousand Dollars ($2,000),
including, without limitation, reasonable attorneys' fees, charges and
disbursements actually incurred in connection with the review, processing and
documentation of such request ;

               25.7.4 Other than with respect to any subleases to the CytRx
Corporation or its affiliates by the Tenant pursuant to Section 25.2, if
Tenant's transfer of rights or sharing of the Demised Premises provides for the
receipt by, on behalf or on account of Tenant of any consideration of any kind
whatsoever (including, but not by way of limitation, a premium rental for a
sublease or lump sum payment for an assignment) in excess of the rental and
other charges due


                                      34
<PAGE>   37


Landlord under this Lease, Tenant shall pay to Landlord seventy-five percent
(75%) of said excess, less reasonable amounts for broker commissions and
attorneys' fees actually incurred by Tenant in connection with such sublease or
assignment. If said consideration consists of cash paid to Tenant, said payment
to Landlord shall be made upon receipt by Tenant of said cash payment;

               25.7.5 Written agreement from any applicable sublessee that in
the event Landlord gives such third party notice that Tenant is in default
under this Lease, such sublessee shall thereafter make all payments otherwise
due Tenant directly to Landlord, which payments will be received by Landlord
without any liability to Landlord except to credit such payment against amounts
due under the Lease, and any such sublessee shall agree to attorn to Landlord
or its successors and assigns should this Lease be terminated for any reason;
provided, however that in no event shall Landlord or its successors or assigns
be obligated to accept such attornment;

               25.7.6 Any such transfer and consent shall be effected on forms
reasonably approved by Landlord as to form and substance;

               25.7.7 Tenant shall not then be in Default hereunder in any
respect;

               25.7.8 Such third party's proposed use of the Demised Premises
shall be the same as Tenant's permitted use;

               25.7.9 Landlord shall not be bound by any provision of any
agreement pertaining to Tenant's transfer of rights or subletting of the
Demised Premises; provided, however, that no permitted transfer or subletting
shall relieve Landlord from any of its obligations under this Lease;

               25.7.10 Any agreement pertaining to Tenant's transfer of rights
or subletting of the Premises shall be in a form reasonably acceptable to
Landlord and any such agreement shall not be modified or amended without
Landlord's prior written consent, which consent shall not be unreasonably
withheld. Tenant acknowledges and agrees that it shall be reasonable for
Landlord to withhold its consent to any agreement which, it Landlord's opinion,
contains any provision which would negatively impact Landlord's status as a
real estate investment trust;

               25.7.11 Tenant shall deliver to Landlord one original executed
copy of any and all written instruments evidencing or relating to Tenant's
transfer of rights or subletting of the Demised Premises; and

               25.7.12 A list of Hazardous Materials, certified by the proposed
sublessee to be true and correct, which the proposed sublessee intends to use
or store in the Demised Premises. Additionally, Tenant shall deliver to
Landlord, on or before the date any proposed sublessee takes occupancy of the
Demised Premises, all of the items required pursuant to Section 39 relating to
Hazardous Materials of such proposed sublessee.



                                      35
<PAGE>   38

         25.8.  Any sale, assignment, hypothecation or transfer of this Lease or
subletting of the Demised Premises that is not in compliance with the
provisions of this Section 25 shall be void and shall, at the option of
Landlord, terminate this Lease.

         25.9.  The consent by Landlord to an assignment or subletting shall not
relieve Tenant or any assignees of this Lease or sublessee of the Demised
Premises from obtaining the consent of Landlord to any further assignment or
subletting nor shall it release Tenant or any assignee or sublessee of Tenant
from full and primary liability under the Lease.

         25.10. Notwithstanding any subletting or assignment Tenant shall
remain fully and primarily liable for the payment of all Rent and other sums
due, or to become due hereunder, and for the full performance of all other
terms, conditions, and covenants to be kept and performed by Tenant. The
acceptance of Rent or any other sum due hereunder, or the acceptance of
performance of any other term, covenant, or condition thereof, from any other
person or entity shall not be deemed to be a waiver of any of the provisions of
this Lease or a consent to any subletting, assignment or other transfer of the
Demised Premises.

         25.11. If Tenant delivers to Landlord an Assignment Notice indicating
a desire to transfer this Lease to a transferee other than the Proceutics
Purchaser or as provided within Section 25.4, then Landlord shall have the
option, exercisable by giving notice to Tenant at any time within ten (10) days
after Landlord's receipt of the Assignment Notice, to terminate this Lease as
of the date specified in the Assignment Notice as the Assignment Date. If
Landlord exercises such option, then Tenant shall have the right to withdraw
such Assignment Notice by delivery to Landlord written notice of such election
within five (5) days after Landlord's delivery of notice electing to exercise
such option to terminate. In the event Tenant withdraws the Assignment Notice,
this Lease shall continue in full force and effect as if such Assignment Notice
had not been given. If Tenant fails to withdraw the Assignment Notice as
hereinabove provided, this Lease, and the term and estate herein granted, shall
terminate as of the Assignment Date. No failure of Landlord to exercise any
such option to terminate this Lease shall be deemed to be Landlord's consent to
the proposed Assignment, Sublease or other Transfer.

         25.12. If Tenant shall sublet the Demised Premises or any part, Tenant
hereby immediately and irrevocably assigns to Landlord, as security for
Tenant's obligations under this Lease, all rent from any subletting of all or a
part of the Demised Premises, and Landlord as assignee and as attorney-in-fact
for Tenant, or a receiver for Tenant appointed on Landlord's application, may
collect such rent and apply it toward Tenant's obligations under this Lease;
except that, until the occurrence of a Default by Tenant, Tenant shall have the
right to collect such rent.

26.      Attorneys' Fees and Costs

         Tenant shall be responsible for (i) all of Tenant's legal and related
costs and fees in connection with this Lease, and (ii) all of Landlord's
reasonable legal and related costs and fees actually incurred if Landlord is
required to consult an attorney regarding the administration or enforcement of
this Lease. If either party commences an action against the other party arising
out of or in connection with this Lease, the prevailing party shall be entitled
to have and recover from the non-prevailing party reasonable attorneys' fees,
charges and disbursements and costs of suit actually incurred.

27.      Bankruptcy

         27.1. In the event a debtor, trustee, or debtor in possession under
the Bankruptcy Code, or other person with similar rights, duties and powers
under any other law, proposes to cure any default under this Lease or to assume
or assign this Lease, and is obliged to provide adequate assurance to Landlord
that (i) a default will be cured, (ii) Landlord will be compensated for its
damages arising from any breach of this Lease, or (iii) future performance
under this Lease will occur, then adequate assurance shall include any or all
of the following, as designated by Landlord:

               27.1.1 Those acts specified in the Bankruptcy Code or other law
as included within the meaning of adequate assurance, even if this Lease does
not concern a shopping center or other facility described in such laws;

               27.1.2 A prompt cash payment to compensate Landlord for any
monetary defaults or actual damages arising directly from a breach of this
Lease;

               27.1.3 A cash deposit in an amount at least equal to the
Security Deposit as referenced in 2.1.8 originally required at time of
execution of this Lease.

               27.1.4 The assumption or assignment of all of Tenant's interest
and obligations under this Lease.

28.      Estoppel Certificate

         Each of Tenant and Landlord shall, within ten (10) days of written
notice from the other party hereto, execute, acknowledge and deliver a
statement in writing substantially in the form attached to this Lease as
Exhibit "E" with the blanks filled in, and on any other form reasonably
requested by a proposed lender or purchaser, (i) certifying that this Lease is
unmodified and in full force and effect (or, if modified, stating the nature of
such modification and certifying that this Lease as so modified is in full
force and effect) and the dates to which


                                      37
<PAGE>   40


the rental and other charges are paid in advanced, if any, (ii) acknowledging
that there are not, to such party's knowledge, any uncured defaults on the part
of the other party hereunder, or specifying such defaults if any are claimed
and (iii) setting forth such further information with respect to this Lease or
the Demised Premises as may be reasonably requested thereon. Any such statement
may be relied upon by any prospective purchaser or encumbrancer of all or any
portion of the Lease or the real property of which the Demised Premises are a
part. Failure to deliver such statement within such time shall, at the option
of the requesting party, constitute a Default under this Lease, and, in any
event, shall be conclusive upon the non-requesting party that the Lease is in
full force and effect and without modification except as may be represented by
the requesting party in any certificate prepared and delivered for execution.

29.      Joint and Several Obligations

         29.1. If more than one person or entity executes this Lease as Tenant,

               29.1.1 Each of them is jointly and severally liable for the
keeping, observing and performing of all of the terms, covenants, conditions,
provisions and agreements of this Lease to be kept, observed and performed by
Tenant, and

               29.1.2 The term "Tenant" as used in this Lease shall mean and
include each of them jointly and severally. The act of, notice from, notice to,
refund to, or the signature of, any one or more of them, with respect to the
tenancy of this Lease, including, but not limited to, any renewal, extension,
expiration, termination or modification of this Lease, shall be binding upon
each and all of the persons executing this Lease as Tenant with the same force
and effect as if each and all of them had so acted, so given or received such
notice or refund or so signed.

30.      Definition of Landlord; Limitation of Landlord's Liability

         30.1. The term "Landlord" as used in this Lease, so far as covenants
or obligations on the part of Landlord are concerned, shall be limited to mean
and include only Landlord or the successor-in-interest of Landlord under this
Lease at the time in question. In the event of any transfer, assignment or the
conveyance of Landlord's fee title or leasehold interest, the landlord herein
named (and in case of any subsequent transfers or conveyances, the then
grantor) shall, subject to the provisions of Section 9.3, be freed and relieved
from, and after the date of such transfer, assignment or conveyance, of all
liability for the performance of any covenants or obligations contained in this
Lease thereafter to be performed by Landlord and, without further agreement,
the transferee of such title or leasehold shall be deemed to have assumed and
agreed to observe and perform any and all obligations of Landlord hereunder.
Landlord may transfer its interest in the Demised Premises or this Lease
without the consent of


                                      38
<PAGE>   41


Tenant and such transfer or subsequent transfer shall not be deemed a violation
on the part of Landlord or the then grantor of any of the terms or conditions
of this Lease.

         30.2. If Landlord is in default of this Lease, and as a consequence,
Tenant recovers a money judgment against Landlord, the judgment shall be
satisfied only out of the proceeds of sale received on execution of the
judgment and levy against the right, title and interest of Landlord in the
Building, and out of rent or other income from such real property receivable by
Landlord , including insurance and condemnation proceeds actually received but
not used in the repair of the property, or out of the consideration received by
Landlord from the sale, financing, refinancing, or other disposition of all or
any part of Landlord's right, title, and interest in the Building and Project.

         30.3. Landlord shall not be personally liable for any deficiency. If
Landlord is a partnership or joint venture, the partners of such partnership
shall not be personally liable and no partner of Landlord shall be sued or
named as a party in any suit or action or service of process be made against
any partner of Landlord except as may be necessary to secure jurisdiction of
the partnership or joint venture. If Landlord is a corporation, the
shareholders, directors, officers, employees, and/or agents of such corporation
shall not be personally liable and no shareholder, director, officer, employee
or agent of Landlord shall be sued or named as a party in any suit or action or
service of process made against any shareholder, director, officer, employee or
agent of Landlord. No partner, shareholder, director, employee, or agent of
Landlord shall be required to answer or otherwise plead to any service of
process and no judgment will be taken or writ of execution levied against any
partner, shareholder, director, employee or agent of Landlord.

         30.4. Each of the covenants and agreements of this Section 30 shall be
applicable to any covenant or agreement either expressly contained in this
Lease or imposed by statute or by common law and shall survive the termination
of this Lease.

31.      Project Control by Landlord

         31.1. Landlord reserves full control over the Building and the Project
to the extent not inconsistent with Tenant's enjoyment of the Demised Premises
pursuant to the terms of this Lease. This reservation includes but is not
limited to right of Landlord to expand the Project, subdivide the Project,
convert the Building and or other buildings within the Project to condominium
units, the right to grant easements and licenses to others and the right to
maintain or establish ownership of the Building separate from fee title to the
land on which the Building is located. Notwithstanding anything to the contrary
set forth herein, Landlord shall not (i) alter the Demised Premises without
Tenant's consent, which shall not be unreasonably withheld, conditioned or
delayed with respect to nonmaterial


                                      39
<PAGE>   42


alterations which do not affect Tenant's use of the Demised Premises as
contemplated by this Lease or as may be required by any governmental entity, or
(ii) grant any rights to any third party to occupy any portion of the Demised
Premises or any of the parking spaces of Tenant which comprise the Parking
Allotment.

         31.2. Landlord further reserves the right to combine the Project with
any other project in the area of the Project and owned by Landlord or its
affiliates.

         31.3. Tenant shall, should Landlord so request, promptly join with
Landlord in execution of such documents as may be reasonably appropriate to
assist Landlord to implement any such action, provided that Tenant need not
execute any document which is of nature wherein liability is created in Tenant
or, if by reason of the terms of such document, Tenant will be deprived of the
quiet enjoyment and use of the Demised Premises as granted by this Lease.

         31.4. Landlord may, at any and all reasonable times during
non-business hours (or during business hours if Tenant so requests), and upon
reasonable advance notice (provided that no time restrictions shall apply or
advance notice need be given if an emergency necessitates an immediate entry),
enter the Demised Premises to (a) inspect the same and to determine whether
Tenant is in compliance with its obligations hereunder, (b) supply any service,
perform any obligation or exercise any right which Landlord is permitted to
exercise or required to supply or perform hereunder, (c) show the Demised
Premises to prospective lenders, insurers, investors, purchasers or, during the
last year of the Term, tenants, (d) post notices of nonresponsibility, and (e)
access the telephone equipment, electrical substation and fire risers. Tenant,
at Tenant's sole cost and expense, shall have the right to require that a
representative of Tenant accompany Landlord during any such entry (provided
that Landlord shall not be required to seek accompaniment of Tenant if an
emergency necessitates an immediate entry), and Tenant shall not unreasonably
withhold, condition or delay scheduling such accompaniment. In connection with
any such alteration, improvement or repair, Landlord may erect in the Demised
Premises or elsewhere in the Building or the Project scaffolding and other
structures reasonably required for the work to be performed. In no event shall
Tenant's Rent abate as a result of any such entry or work; provided, however,
that all such work shall be done in such a manner as to cause as little
interference with the use of the Demised Premises as contemplated by this Lease
by Tenant and its permitted subtenants as reasonably possible. Landlord shall
at all times retain a key with which to unlock all of the doors in the Demised
Premises subject to Tenant's rights to establish "secure" areas pursuant to
Section 10.5. If an emergency necessitates immediate access to the Demised
Premises, Landlord may use whatever force is necessary to enter the Demised
Premises and any such entry to the Demised Premises shall not constitute a
forcible or unlawful entry to the Demised Premises, an unlawful detainer of the
Demised Premises, or an eviction of Tenant from the Demised Premises, or any
portion thereof.


                                      40
<PAGE>   43

Notwithstanding anything to the contrary set forth herein, Tenant hereby
indemnifies and agrees to defend and hold Landlord, its agents and contractors
harmless from and against any and all claims, costs and liabilities including
reasonable and actual attorneys' fees, charges and disbursements, arising out
of or in connection with any injury, damage or other loss resulting from or
arising out of Landlord's inability to access all or any part of the Demised
Premises or the Building, including, without limitation, due to Tenant's
failure to provide access to any "secure" area or to arrange for Landlord to be
accompanied by a representative of Tenant.

         31.5. Landlord reserves the right to modify the Land and the exterior
portions of the Building, including the right to add or remove landscaping

32.      Quiet Enjoyment

         So long as Tenant is not in default, Landlord covenants that Landlord
or anyone acting through or under Landlord will not disturb Tenant's occupancy
of the Demised Premises except as permitted by the provisions of this Lease.

33.      Quitclaim Deed

         Tenant shall execute and deliver to Landlord on the expiration or
termination of this Lease, immediately on Landlord's request, in recordable
form, a quitclaim deed to the Demised Premises or such other documentation
reasonably requested by Landlord evidencing termination of this Lease.

34.      [Intentionally Omitted.]

35.      Subordination and Attornment

         35.1. Provided that Tenant receives a non-disturbance agreement from
any applicable mortgagee, beneficiary or landlord in substantially the same
form as Exhibit "F" attached hereto (the "Nondisturbance Agreement"), this
Lease shall be subject and subordinate to the lien of any mortgage, deed of
trust, or lease in which Landlord is tenant now or hereafter in force against
the Project and the Building and to all advances made or hereafter to be made
upon the security thereof without the necessity of the execution and delivery
of any further instruments on the part of Tenant to effectuate such
subordination.

         35.2. Notwithstanding the foregoing, Tenant shall execute and deliver
upon demand such further instrument or instruments evidencing such
subordination of this Lease to the lien of any such mortgage or mortgages or
deeds of trust or lease in which Landlord is tenant as may be required by
Landlord. However, if any such mortgagee, beneficiary or Landlord under lease
wherein Landlord is tenant so elects, this Lease shall be deemed prior in lien
to any such lease, mortgage, or deed of trust upon or including the Demised


                                      41
<PAGE>   44

Premises regardless of date and Tenant will execute a statement in writing to
such effect at Landlord's request. If Tenant fails to execute any document
required from Tenant under this Section within ten (10) days after written
request therefor, Tenant hereby constitutes and appoints Landlord or its
special attorney-in-fact to execute and deliver any such document or documents
in the name of Tenant. Such power is coupled with an interest and is
irrevocable.

         35.3. In the event any proceedings are brought for foreclosure, or in
the event of the exercise of the power of sale under any mortgage or deed of
trust made by the Landlord covering the Demised Premises, the Tenant shall at
the election of the purchaser at such foreclosure or sale attorn to the
purchaser upon any such foreclosure or sale and recognize such purchaser as the
Landlord under this Lease.

36.      Surrender

         36.1. No surrender of possession of any part of the Demised Premises
shall release Tenant from any of its obligations hereunder unless accepted by
Landlord.

         36.2. The voluntary or other surrender of this Lease by Tenant shall
not work a merger, unless Landlord consents and shall, at the option of
Landlord, operate as an assignment to it of any or all subleases or
subtenancies.

         36.3. The voluntary or other surrender of any ground or underlying
lease that now exists or may hereafter be executed affecting the Building or
the Project, or a mutual cancellation, thereof, or of Landlord's interest
therein, shall not work a merger and shall, at the option of the successor of
Landlord's interest in the Building or Project, operate as an assignment of
this Lease.

         36.4. Upon the expiration or earlier termination of this Lease, Tenant
shall surrender the Demised Premises to Landlord broom clean and free of
debris; with all of Tenant's personal property and effects removed therefrom;
with all alterations, improvements and fixtures required by Landlord in
accordance with Section 17 to be removed from the Demised Premises actually
removed and all damage as a result of or caused by such removal repaired; and
with all licenses, permits and similar items held or obtained by or at the
request of Tenant which restrict or affect the used of the Demised Premises
released and fully terminated.

37.      Waiver and Modification

         No provision of this Lease may be modified, amended or added to except
by an agreement in writing. The waiver by Landlord of any breach of any term,
covenant or condition herein contained shall not be deemed to be a waiver of
any subsequent breach of the same or any other term, covenant or condition



                                      42
<PAGE>   45

herein contained.

38.      Waiver of Jury Trial and Counterclaims

         THE PARTIES HERETO SHALL AND THEY HEREBY DO WAIVE TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HERETO
AGAINST THE OTHER ON ANY MATTERS WHATSOEVER ARISING OUT OF OR IN ANY WAY
CONNECTED WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, TENANT'S
USE OR OCCUPANCY OF THE DEMISED PREMISES, AND OR ANY CLAIM OF INJURY OR DAMAGE.

39.      Hazardous Materials

         39.1. Prohibition/Compliance. Tenant shall not cause or permit any
Hazardous Materials (as hereinafter defined) to be brought upon, kept or used
in or about the Demised Premises (including without limitation, the Storage
Area), the Building or the Project in violation of applicable law by Tenant,
its agents, employees, contractors or invitees. If Tenant breaches the
obligation stated in the preceding sentence, or if the presence of Hazardous
Materials in or on the Demised Premises (including without limitation the
Storage Area), the Building or the Land results in contamination of the Demised
Premises, the Building, the Project or any adjacent property or if
contamination of the Demised Premises, the Building or the Land by Hazardous
Materials otherwise occurs during the term of this Lease or any extension or
renewal hereof or holding over hereunder, Tenant hereby indemnifies and shall
defend and hold Landlord, its officers, directors, employees, agents and
contractors harmless from any and all claims, judgments, damages, penalties,
fines, costs, liabilities, or losses actually incurred (including, without
limitation, diminution in value of the Demised Premises or any portion of the
Building or the Project, damages for the loss or restriction on use of rentable
or usable space or of any amenity of the Demised Premises, the Building or the
Project, damages arising from any adverse impact on marketing of space in the
Demised Premises, the Building or the Project, and sums paid in settlement of
claims, including reasonable attorneys' fees, consultant fees and expert fees
actually incurred) which arise during or after the Lease term as a result of
such contamination. This indemnification of Landlord by Tenant includes,
without limitation, reasonable costs actually incurred in connection with any
investigation of site conditions or any cleanup, remedial, removal, or
restoration work required by any federal, state or local governmental agency or
political subdivision because of Hazardous Materials present in the air, soil
or ground water above on or under the Demised Premises. Without limiting the
foregoing, if the presence of any Hazardous Materials on the Demised Premises,
the Building, the


                                      43
<PAGE>   46



Project or any adjacent property, caused or permitted by Tenant results in any
contamination of the Demised Premises, the Building, the Project or any
adjacent property, Tenant shall promptly take all actions at its sole expense
as are necessary to return the Demised Premises, the Building, the Project or
any adjacent property, to the condition existing prior to the time of such
contamination, provided that Landlord's approval of such action shall first be
obtained, which approval shall not unreasonably be withheld so long as such
actions would not potentially have any material adverse long-term or short-term
effect on the Demised Premises, the Building or the Project.

         39.2. Business. Landlord acknowledges that it is not the intent of
this Section 39 to prohibit Tenant from operating its business as described in
Section 2.1.9 above. Tenant may operate its business according to the custom of
the industry so long as the use or presence of Hazardous Materials is strictly
and properly monitored according to all applicable governmental requirements.
As a material inducement to Landlord to allow Tenant to use Hazardous Materials
in connection with its business, Tenant agrees to deliver to Landlord prior to
the Term Commencement Date a list identifying each type of Hazardous Materials
to be present on the Demised Premises and setting forth any and all
governmental approvals or permits required in connection with the presence of
such Hazardous Materials on the Demised Premises ("Hazardous Materials List ").
Tenant shall deliver to Landlord an updated Hazardous Materials List at least
once a year and shall also deliver an updated list before any new Hazardous
Materials is brought onto the Demised Premises. Tenant shall deliver to
Landlord true and correct copies of the following documents (the "Documents")
relating to the handling, storage, disposal and emission of Hazardous Materials
prior to the Term Commencement Date, or if unavailable at that time, concurrent
with the receipt from or submission to a governmental agency: permits;
approvals; reports and correspondence; storage and management plans, notice of
violations of any laws; plans relating to the installation of any storage tanks
to be installed in or under Building or the Project (provided, said
installation of tanks shall only be permitted after Landlord has given Tenant
its written consent to do so, which consent may be withheld in Landlord's sole
and absolute discretion); and all closure plans or any other documents required
by any and all federal, state and local governmental agencies and authorities
for any storage tanks installed in, on or under the Building or the Project for
the closure of any such tanks. Tenant is not required, however, to provide
Landlord with any portion(s) of the Documents containing information of a
proprietary nature which, in and of themselves, do not contain a reference to
any Hazardous Materials or hazardous activities. It is not the intent of this
Section to provide Landlord with information which could be detrimental to
Tenant's business should such information become possessed by Tenant's
competitors. Tenant agrees that it shall, at its own expense, and upon the
written request of Landlord, establish and maintain a separate area of the
Demised Premises for the use and storage of Hazardous Materials.

         39.3. Termination of Lease/Withholding Approval of Assignment or
Sublease. Notwithstanding the provisions of Section 39.1 above, if Tenant or
any existing sublessee of Tenant, with respect to the Demised Premises or the
Project, or any proposed assignee or sublessee, with respect to any property,
is


                                      44
<PAGE>   47


subject to an uncured enforcement order issued by any governmental authority in
connection with the use, disposal or storage of Hazardous Materials, Landlord
shall have the right, with respect to any such matter involving Tenant or an
existing sublessee of Tenant, to terminate this Lease in Landlord's sole and
absolute discretion, and, with respect to any such matter involving a proposed
assignee or sublessee, it shall not be unreasonable for Landlord to withhold
its consent to any proposed assignment or subletting. Notwithstanding the
foregoing, after the first occurrence of any event with respect to Tenant or
any existing sublessee of Tenant described above (a "Termination Event"),
Landlord shall deliver written notice to Tenant, and such sublessee, if
applicable, of the occurrence of such event and Tenant shall have thirty (30)
days after receipt of such notice to cure, or cause to be cured, the condition
causing such Termination Event. After the expiration of such thirty (30) day
period, or upon the occurrence of any subsequent Termination Event, Landlord
shall have the right to terminate this Lease in Landlord's sole and absolute
discretion.

         39.4. Testing. At any time, and from time to time, prior to the
expiration or earlier termination of the Term, Landlord shall have the right to
conduct appropriate tests of the Demised Premises, the Building and the Project
to demonstrate that contamination has occurred as a result of Tenant's use of
the Demised Premises. Tenant shall be solely responsible for and shall defend,
indemnify and hold the Landlord, its agents and contractors harmless from and
against any and all claims, costs and liabilities including reasonable and
actual attorneys' fees, charges and disbursements, arising out of or in
connection with any removal, clean up, restoration and materials required
hereunder to return the Demised Premises and any other property of whatever
nature to their condition existing prior to the time of any such contamination.
Tenant shall pay for the actual and reasonable cost of the tests of the Demised
Premises if contamination is determined to have occurred.

         39.5. Underground Tanks. If underground or other storage tanks storing
Hazardous Materials are located on the Demised Premises or are hereafter placed
on the Demised Premises by any party, Tenant shall monitor the storage tanks,
maintain appropriate records, implement reporting procedures, properly close
any underground storage tanks, and take or cause to be taken all other steps
necessary or required under any applicable federal, state or local laws, rules,
regulations or ordinances as they now exist or may hereafter be adopted or
amended.

         39.6. Tenant's Obligations. Tenant's obligations under this Section 39
shall survive the expiration or earlier termination of the Lease. Tenant shall
be deemed to be in occupancy of the Demised Premises during any period of time
employed by Tenant or Landlord after the termination of this Lease to complete
the removal from the Demised Premises of any such Hazardous Materials and the
release and termination of any licenses or permits restricting the use of the
Demised Premises.
