shall be construed to incorporate all of the terms provided under each such

2.1.     Premises. The Landlord hereby leases to the Tenant and the Tenant hires
and takes from the Landlord the Premises located in the improved buildings) on
the Property (the "Building"), subject to and with the benefits of the terms,
covenants, conditions and provisions of this Lease, together with appurtenances
specifically granted in this Lease, but reserving to the Landlord (I) the use of
(a) the exterior faces of all exterior walls and (b) the roof, and (ii) the
right (but not the obligation) to install, maintain, use, repair and replace
pipes, ducts, conduits and wire through the Premises and serving the other parts
of the Building. For the purposes of this Lease, the Premises shall be
conclusively deemed to consist of the number of square feet of Leased Area as
set forth in Section 1.1. hereof.

2.2.     Term. The Term shall commence on the Commencement Date, and shall end
at Noon on the last day of the Lease Term, unless sooner terminated as
hereinafter provided.

2.3.     Early Termination Right. Provided Tenant is not in then in default
under this Lease, Tenant shall have the right to terminate this Lease (as to
all, but not less than all of the Premises) prior to the expiration date of the
Term, upon not less than ninety (90) days written notice of termination (the
"Termination Notice") from Tenant to Landlord specifying the termination date
(the "Termination Date") of the Lease (which shall be not earlier than ninety
(90) days after the date of the Termination Notice) accompanied by a payment
(the "Termination Payment) of all Annual Minimum Rent, sales tax thereon and
other sums due under this Lease through the Termination Date. Upon issuance of
the Termination Notice and payment of the Termination Payment, the expiration
date of the Term shall be the Termination Date, Tenant shall vacate the Premises
not later than midnight, Orlando, Florida time on the Termination Date, and
thereupon neither Landlord nor Tenant shall have any further rights, interests
or obligations under this Lease except for adjustment and collection of
Additional Rent pursuant to Section 4.3 of this Lease and other matters which
expressly survive the termination or expiration of this Lease.

3.       Improvements.

3.1.     (Intentionally Omited.]

3.2.     Ownership of Improvements. All improvements to the Premises shall
remain the property of the Landlord. In no event shall Tenant make any
improvements or alterations to the Premises, including the installation and
removal of trade fixtures, without the prior written consent of Landlord, which
shall not be unreasonably withheld nor delayed.

4.       Rent and Other Payments.

4.1.     Payment. All Rent and other charges payable to the Landlord under any
provision of this Lease shall be paid to the Landlord, or as the Landlord may
otherwise designate, in lawful money of the United States at the address of the
Landlord or at such other place as the Landlord in writing may designate,
without any set-off or deduction whatsoever, and without any prior demand
therefor. In addition to the payment of the Rent and other charges, the Tenant
shall also pay to the Landlord, at the time of payment of such Rent and other
charges, all sales, use and/or occupancy-taxes payable by virtue of any such
payments. Rent for any period beginning during the term hereof which is for less
than one (1) month shall be a prorated portion of the monthly installment.

4.2.     Annual Minimum Rent. The Tenant shall pay the Annual Minimum Rent, in
equal monthly installments in advance on the first day of each calendar month
included in the Lease Term. The first monthly installment shall be paid on the
signing of this Lease if not previously delivered. Tenant acknowledges that late
payment by Tenant to Landlord of Rent or other sums due hereunder will cause
Landlord to incur costs not contemplated by this Lease, the exact amount of
which would be extremely difficult and impractical to ascertain. Such costs
include, but are not limited to, processing and account charges, and late
charges which may be imposed on Landlord by the terms of any Mortgage
encumbering the Premises. Therefore, in the event any installment of Rent or any
sum due hereunder is not paid within five (5) days after such amount is due,
Tenant shall pay to Landlord as Additional Rent, a late charge equal to five

<PAGE>

percent (5%) of each such installment or other sum or Twenty Five ($25.00)
Dollars per month, whichever is greater. A sum of Fifteen ($15.00) Dollars shall
also be due from and paid by Tenant to Landlord for each check which is returned
due to insufficient funds, and Tenant shall pay a charge of One Hundred Fifty
Dollars ($150.00) for preparation of a demand for delinquent rent in addition to
all other sums due by Tenant under this Lease.

         4.3. Additional Rent. Tenant shall pay to Landlord, in addition to
Annual Minimum Rent, in the form of Additional Rent (plus any applicable tax),
its Proportionate Share of increased Operating Expenses over the Base Year
Amount as defined in Section 1.1 of this Lease. Should Tenant exercise any
expansion option under the Lease, the foregoing Proportionate Share shall be
adjusted accordingly. In no event shall those Operating Expenses of which
Landlord has control (i.e. those which may be competitively bid) increase by
more than five (5%) percent annually. Specifically excluded as controllable
expenses are real estate taxes, insurance and utilities.

           Within thirty (30) days after the first twelve (12) months of the
Term and each anniversary thereafter, Landlord shall deliver to Tenant a
statement setting forth the amount of increases in Operating Expenses over the
Base Year Amount for the preceding twelve (12) month period, together with an
invoice showing the amount due Landlord from Tenant under such increases. Tenant
shall pay any increases over the Base Year Amount within thirty (30) days from
receipt of the statement and invoice, whether or not Tenant disputes the
accuracy of such statement, Tenant reserving the right at its expense to audit
Landlord's records in support of such statement.

           The term "Real Estate Taxes" shall mean the annual taxes and any
special assessments or other charges levied against the real property of which
the Prenu'ses are a part by any authority having the direct power so to tax,
including any city, county, state or Federal government, or any school,
agricultural, transportation or environmental control agency, lighting drainage,
or other improvement district hereof, and shall include the expense of
contesting the amount of validity of any such taxes, charges or assessments. The
term "Operating Expenses" shall include the annual expenses of Landlord for the
operation and maintenance of the Premises and Building which are reasonable or
customary for the operation of this type of Premises and Building, and shall
include, but not be limited to, management salaries, maintenance and janitorial
expense, administrative salaries, costs and fees, insurance, security,
landscaping and any capital expenditures required under any governmental law,
rule or regulation that was not applicable to the building at the time it was
originally constructed but excluding all other capital expenditures (except as
noted below). The term "Utility Costs" shall include Landlord's annual expenses
for the operation and maintenance of the Building and the Premises with respect
to utility charges for furnishing heat, air-conditioning, electricity, water,
sewage, gas, garbage removal, etc. If the final Lease year (to include renewals)
during which escalation may occur shall contain less than twelve (12) months,
the increase hereunder shall be prorated, the Tenanf s obligation to pay such
increases to survive the expiration of the Lease (and renewal) term.

         If the Landlord in its sole discretion in operating the Building
chooses to install any energy or labor saving devices, equipment, fixtures or
appliances to or in the Building that otherwise might be considered a capital
expenditure, then the Landlord may depreciate the cost of the equipment or
fixture into Operating Expenses of the Building, including interest at a
reasonable rate, all according to generally accepted accounting principles
applied on a consistent basis.

5.       Utility Services and Maintenance by Landlord. The Landlord shall cause
the necessary mains, conduits and other facilities to be provided to supply
water, sanitary sewer facilities and electricity into the Premises, and the
Tenant hereby acknowledges that the Landlord has complied with the provisions of

arising from such usage. In addition, if Tenant uses water or produces refuse in
excess of normal use, Landlord, in its discretion may allocate Tenant the
increased cost for such services as reasonably measured or estimated by
Landlord, and Tenant shall pay Landlord, on demand, any increased cost so
reasonably measured or estimated. Landlord agrees to furnish the following

such policy or policies of insurance shall be used for the repair or replacement
of the property and equipment insured. Landlord will not carry insurance on
Tenant's property. Tenant shall fumish Landlord with a certificate that such
insurance is in force and effect during the Term of this Lease, which

invoices from Landlord, reimburse Landlord for such increase in premiums. It is
understood and agreed between the parties hereto that any such increase in
premiums because of the nature of Tenant's operation shall be considered as
Annual Minimum Rent due and shall be included in any lien for rent.

sending of such notice; (ii) the name of the proposed subtenant or assignee;
(iii) the nature of the proposed subtenant's or assignee's business to be
carried on in the Premises; (iv) the terms and provisions of the proposed
sublease or assignment; (v) a current audited fniancial statement of the
proposed subtenant or assignee; and (vi) such additional information concerning
the proposed assignment or sublease and proposed assignee or sublessee as the
Landlord may reasonably request.

9.3.     Landlord's Option to Terminate. Upon receipt from Tenant of a Notice of
Intention to Assign or Sublease, Landlord shall have the right to terminate this
Lease and relet the Premises, or, in the event of a proposed assignment or
subletting of less than the entire Premises, to recapture that portion of the
Premises, such right to be exercised by giving notice to the Tenant within
thirty (30) days after receipt of Tenant's Notice of Intention to Assign or
Sublease. If such notice of termination or recapture, as the case may be, is
given by Landlord, it shall become effective thirty (30) days after the giving
thereof, whereupon Tenant shall vacate and surrender possession of the Premises
or portion thereof, as the case may be, to Landlord.

9.4.     Assignment or Sublease Profit. In the event of any assignment or
sublease of all or any portion of the Premises, having first been approved by
Landlord, where the rental reserved in the assignment or sublease exceeds the
rental or prorata portion of the rental, as the case may be, for such space
reserved in the Lease, Tenant shall pay Landlord monthly, as Additional Rent, at
the same time as the monthly installments of Rent required hereunder, the excess
of the rental reserved in the assignment or sublease over the rental reserved in
this Lease applicable to the assigned or subleased space.

9.5.     Permission for Tenant to Assign or Sublease. The granting of permission
for Tenant to assign or sublease the Premises on any one or more occasions shall
not constitute ipso facto waiver of the requirement imposed hereby that the
written consent of the Landlord be obtained for any subsequent or other
assignment or subletting, and the acceptance of rent checks and the negotiation
of same, or the acceptance of rent payments in any other fashion, from any
assignee or sublessee, whether or not Landlord had knowledge of the assignment
or sublease under which such assignee or sublessee claims, shall not constitute
ipso facto consent by Landlord to such assignment or sublease or constitute a
waiver of the restrictions upon assignment and subletting imposed in this
section.

10.      Assumption of Risk, Indemnification and Hold Harmless. Tenant shall and
hereby does indemnify an(f hold harmless Landlord, its management company,
agents, servants and employees against and from any and all claims arising from
Tenant's use of the Premises or from any activity, work or thing done, permitted
or suffered by the Tenant in or about the Premises, and shall further indemnify
and hold harmless Landlord against and from any and all claims arising from any
breach or default in the performance of any obligations on Tenant's part to be
performed under the terms of this Lease, or arising from any act, neglect, fault
or omission of the Tenant, or of its agents or employees, and from and against
all costs, attorneys' fees, paralegals' fees, expenses and liabilities incurred
in or about such claim or any action or proceeding brought thereon. Tenant upon
notice from Landlord shall defend the same at Tenant's expense by counsel
reasonably satisfactory to Landlord. Tenant hereby assumes all risk of damage to
property or injury to persons in, upon or about the Premises from any cause
whatsoever, except that which is caused by the failure of Landlord to observe
any of the terms and conditions of this Lease and such failure has persisted for
an unreasonable period of time after written notice from Tenant to Landlord of
such failure.

<PAGE>

11.      Landlord's Liability. The liability under this Lease of Landlord shall
be limited to its interest in the Building of which the Premises are a part; and
Tenant, its successors and assigns, hereby waive all rights to proceed
individually against Landlord, Landlord's management company or agent, or any of
Landlord's partners, officers, directors or shareholders. The term "Landlord",
as used in this Section, shall mean only the owner or owners at the time in
question of the fee simple title to the Property, and in the event of any
transfer of such title or interest Landlord (and in case of any subsequent
transfers, the then grantor) shall be relieved from and after the date of such
transfer of all liability with respect to Landlord's obligations under this
Lease, provided that any funds in the hands of Landlord (or then grantor at the
time of such transfer) in which Tenant has an interest, shall be delivered to
the grantee. The obligations to be performed by Landlord shall, subject to the
foregoing, be binding on Landlord's successors and assigns only during their
respective periods of ownership, and no successor Landlord shall have liability
to Tenant with respect to defaults hereunder occasioned by the acts or omissions
of any predecessor Landlord.

12.      Environmental Provisions.

12.1     Asbestos and Lead Paint Disclosure. Asbestos-containing materials
and/or lead paint may be present in portions of the Premises, generally in the
form of sprayed-on or troweled-on coatings on structural members and ceilings,
painted surfaces surrounding window frames, behind walls or inside finished
support columns. Asbestos previously was a common component of floor tiles. It
is important that asbestos-containing materials and lead paint not be disturbed.
Disturbed asbestos particles when airborne pose a serious health risk. Prior to
undertaking any alterations, repairs or renovations to the Premises, Tenant
shall inform Landlord of its intent to do so in order that Landlord may confirm
that such alterations, repairs or renovations shall not disturb
asbestos-containing materials. In the course of such alterations, repairs or
renovations, if asbestos-containing materials are present in the Premises,
Tenant shall adopt all reasonable measures to remove or encapsulate
asbestos-containing materials. Nothing in this paragraph shall supersede any
other conflicting provisions of this Lease.

12.2     Hazardous Materials Provisions.

12.2.1   Hazardous Materials Covenants. Tenant shall at all times during the
Lease Term comply with the following requirements: (a) Tenant shall not cause,
permit or suffer any Hazardous Material (as hereafter defined) to be brought
upon, treated, kept, stored, disposed of, discharged, released, produced,
manufactured, generated, refined or used upon, about or beneath the Premises or
the Property by Tenant, its agents, employees, contractors, invitees or
licensees (collectively, "Tenant Parties"), except to the extent commonly used
in the day to day operation of the Premises by Tenant in compliance with all
Environmental Requirements (as hereafter defined). (b) Tenant agrees that all
operations or activities upon, or any use or occupancy of the Premises, or any
portion thereof, by Tenant or any Tenant Parties shall be in all respects in
compliance with all Environmental Requirements then governing or in any way
relating to the generation, handling, manufacturing, treatment, storage, use,
transportation, release, spillage, leakage, dumping, discharge or disposal of
any Hazardous Materials. (c) Tenant shall, at its sole costs and expense,
promptly take all actions required by any federal, state or local governmental
agency or political subdivision to mitigate Environmental Damages (as hereafter
defined) which arise directly or indirectly from or in connection with the
presence, suspected presence, release or suspected release of any Hazardous
Material in or into the air, soil, surface water or groundwater at, on, about,
under or within the Premises or Property, or any portion thereof, by Tenant or
Tenant Parties. Such actions shall include, if required by any such governmental
agency or political subdivision, but not be limited to, the investigation of the
environmental condition of the Premises, the Building or any portion of the
Property adversely affected by Tenant's breach of any of the provisions of this
paragraph (the "Affected Property"), and the preparation of and performance of
any cleanup, remediation, containment, operation, maintenance, monitoring or
restoration work, whether on or off of the Affected Property. Tenant shall take
all actions required by any federal, state or local governmental agency or
political subdivision to restore the Affected Property to the condition existing
prior to the introduction of Hazardous Material upon, about or beneath the
Affected Property in accordance with the standard of remediation imposed by
Applicable Law. Tenant shall proceed continuously and diligently with such
investigatory and remedial actions, provided that in all cases such actions
shall be in accordance with all applicable requirements of governmental
entities. Any such actions shall be performed in a good, safe and workmanlike
manner by one or more contractors selected by Tenant, and approved in advance in
writing by Landlord, and under the supervision of a consulting engineer,
selected by Tenant and approved in advance in writing by Landlord, and shall
minimize any impact on the business conducted at the Property. Tenant shall pay
all costs in connection with such investigatory and remedial activities,
including but not limited to the charges of such contractor(s) and consulting
engineer, all power and utility costs, any and all taxes or fees that may be
applicable to such activities, and Landlord's reasonable attorneys' fees,

<PAGE>

paralegals' fees and costs incurred in connection with monitoring or review of
such investigatory and remedial activities. Tenant shall promptly provide to
Landlord copies of testing results and reports that are generated in connection
with the above-mentioned activities. Promptly upon completion of such
investigation and remediation, Tenant shall permanently seal or cap all
monitoring wells and test holes to industrial standards in compliance with
Applicable Laws, remove all associated equipment, and restore the Affected
Property to the maximum extent possible, which shall include, without
limitation, the repair of any surface damage, including paving, caused by such
investigation or remediation hereunder. (d) If Tenant shall become aware of or
receive notice or other communication concerning any actual, alleged, suspected
or threatened violation of Environmental Requirements, or liability of Tenant
for Environmental Damages in connection with the Premises or activities of any
person thereon, then Tenant shall deliver to Landlord, within ten (10) days of
the receipt of such notice or conununication by Tenant, a written description of
said violation, liability, correcting information or actual or threatened event
or condition, together with copies of any documents evidencing same. Receipt of
such notice shall not be deemed to create any obligation on the part of Landlord
to defend or otherwise respond to any such notification. (e) Tenant shall
promptly provide to Landlord the results of any tests and copies of all
registration permits regarding any underground storage tanks located on the
Premises and Tenant shall comply with same. (f) In the event of any default
under this Lease, Landlord shall have the right in its sole and absolute
discretion, but not the duty, to enter upon the Premises at any reasonable time,
at the expense of Tenant, to conduct an inspection thereof, including invasive
tests, and the activities conducted thereon to determine compliance with all
Environmental Requirements and the existence of any Environmental Damages as a
result of the condition of the Premises or any surrounding properties and
activities thereon. Tenant hereby grants to Landlord, and the agents, employees,
consultants and contractors of Landlord, the right to enter upon the Premises
and to perform such tests thereon or therein as are necessary to conduct such
reviews and investigations in accordance with the preceding sentence. Landlord
shall use its best efforts to minimize interference with the business of Tenant
and to restore the Premises to its previous condition, but Landlord shall not be
liable for any interference caused thereby.

12.2.2   Hazardous Materials Definitions. The following terms shall have the
meanings ascribed to them: (a) "Environmental Damages" means all claims,

or in connection with the presence, suspected presence, release or suspected
release of any Hazardous Material in or into the air, soil, surface water or
groundwater at, on, about, under or within the Premises, Building or Property,
or any portion thereof, or any surrounding properties, by Tenant or Tenant
Parties and including, without limitation: (i) Damages for personal injury, or

any and all permits, licenses and other authorizations which may be required
under all Environmental Requirements, including laws relating to emissions,
discharges, release or threatened releases of Hazardous Materials into the
environment (including ambient air, surface water, ground water or land) or
otherwise relating to the manufacture, processing, distribution, use, treatment,
storage, disposal, transport or handling of Hazardous Materials; and (b) Tenant

12.2.5   Survival. Each of the covenants, representations and warranties of
Tenant and Landlord contained in this Section 12 of this Lease shall survive the
termination or earlier expiration of this Lease.

12.3     Radon Disclosure. RADON GAS: Radon is a naturally occurring radioactive
gas that, when it has accumulated in a building in sufficient quantities, may
present health risks to persons who are exposed to it over time. Levels of radon

Florida. Additional information regarding radon and radon testing may be
obtained from the Tenant's County Public Health Unit.

13.      Americans with Disabilities Act. Landlord and Tenant acknowledge that
the Americans with Disabilities Act of 1990 (42 U.S.C. Section 12 1 01 et seq.)
and regulations and guidelines promulgated thereunder, as all of the same may be
amended from time to time (collectively referred to herein as the "ADA")
establish requirements under Title III of the ADA ("Title 111") pertaining to
business operations, accessibility and barrier removal, and that such
requirements may be unclear and may or may not apply to the Premises, Building
or the Property depending upon, among other things: (i) whether Tenant's
business operations are deemed a "place of public accommodations-' or a
"commercial facility", (ii) whether compliance with such requirements is
"readily achievable" or "technically infeasible", and (iii) whether a given
alternative affects a "primary function area" or triggers so-called "path of
travel" requirements. Landlord and Tenant acknowledge and agree that Tenant has
been provided an opportunity to inspect the Premises, the Building and Property
sufficient to determine whether or not the Premises, Building and Property in
their condition current as of the Lease Date deviate in any manner from the ADA
Accessibility Guidelines ("ADAAG") or any other requirements under the ADA
pertaining to the accessibility of the Pren-tises, Building or Property. Tenant
further acknowledges and agrees that except as may otherwise be specifically
provided herein, Tenant accepts the Premises, Building and Property in "as is"
condition and agrees that Landlord makes no representation or warranty as to
whether the Premises, Building or Property conform to the requirements of the
ADAAG or any other requirements under the ADA pertaining to the accessibility of
the Premises, Building or Property. Tenant shall be solely responsible for all
other requirements under the ADA relating to the Tenant or any affiliates or
persons or entities related to the

<PAGE>

Tenant or the Premises, including, without limitation, requirements under Title
I of the ADA pertaining to Tenant's employees and the interior of the Premises.

14.      Destruction and Condemnation.

14.1.    Fire or Other Casualty. In the event of (i) a partial destruction of
the Premises or the Building during the Lease Term which requires repairs to
either the Premises or the Building, or (ii) the Premises or the Building being
declared unsafe or unfit for occupancy by any authorized public authority for
any reason other than Tenant's act, use or occupation, which declaration
requires repairs to either the Premises or Building, Landlord may elect to
commence repairs within sixty (60) days thereof, but such partial destruction
shall in no way serve to annul or void this Lease, except that Tenant shall be
entitled to a proportionate reduction of Rent while such repairs are being made
if the Premises are rendered untenantable thereby. The proportionate reduction
is to be based upon the extent to which the making of repairs shall interfere
with the business carried on by Tenant in the Premises. In the event that
Landlord does not elect to commence repairs within sixty (60) days, or repairs
cannot be made under current laws and regulations, either party may temiinate
this Lease upon ten (10) days' written notice. A total destruction, including
any destruction required by any authorized governmental authority, of either the
Premises or the Building shall terminate this Lease. Landlord shall not be
required to repair any property installed in the Premises by Tenant. Tenant
waives any right under applicable laws inconsistent with this paragraph and, in
the event of a destruction, agrees to accept any offer by Landlord to provide
Tenant with comparable space within the parcel in which the Premises are located
on the same temis as this Lease. Nothing herein shall authorize abatement or
reduction of rent because of total or partial destruction arising out of the
negligent or willful acts of omission or commission by Tenant.

14.2.    Condemnation. If any part of the Premises shall be taken or condemned
for a public or quasi-public use, and a part thereof remains which is suitable
for occupation hereunder, this Lease shall, as to the part so taken, terminate
as of the date title shall vest in a condemnor, and the Rent payable hereunder
shall be adjusted so that the Tenant shall be required to pay for the remainder
of the Term only such portion of such Rent as the number of square feet in the
part remafiiffig after the condemnation bears to the number of square feet in
the entire Premises at the date of condemnation; but, in such event, Landlord
shall have the option to terminate this Lease as of the date when title to the
part so condemned vests in a condemnor. If all or any part of the Premises shall
be taken or condemned so that there does not remain a portion suitable for
occupation, this Lease shall thereupon terminate. If all or a part of the
Premises be taken or condemned, all compensation awarded upon such condemnation
or taking shall go to the Landlord and the Tenant shall have no claim thereto,
and the Tenant hereby irrevocably assigns and transfers to the Landlord any
right to compensation or damages to which the Tenant may be entitled during the
Term hereof by reason of the condemnation of all, or a part, of the Premises.

15.      Defaults and Remedies.

15.1.    Events of Default. The following events shall be deemed to be events of
default by Tenant under this Lease: (i) Tenant shall fail to pay any Rent or any
other sums of money due hereunder and such failure shall continue for a period
of seven (7) days after the date such sum is due; (ii) Tenant shall fail to
comply with any provisions of this Lease or any other agreement between Landlord
and Tenant, all of which terms, provisions and covenants shall be deemed
material; (iii) the leasehold hereunder demised shall be taken on execution or
other process of law in any action against Tenant; (iv) Tenant shall fail to
promptly move into, take possession of, and operate its business on the Premises
when the Premises are ready for occupancy; (v) Tenant shall become insolvent or
unable to pay its debts as they become due, or Tenant notifies Landlord that it
anticipates either condition; (vi) Tenant takes any action to, or notifies
Landlora that Tenant intends to file a petition under any section or chapter of
the United States Bankruptcy Code and rules and regulations promulgated
thereunder, as amended, or under any similar law or statute of the United States
or any state thereof, or a petition shall be filed against Tenant under any such
statute or Tenant or any creditor of Tenant notifies Landlord that it knows such
a petition will be filed or Tenant notifies Landlord that it expects such a
petition to be filed; (vii) a receiver or trustee shall be appointed for
Tenant's leasehold interest in the Premises or for all or a substantial part of
the assets of Tenant.

15.2.    Remedies. In the event of any default or breach by Tenant, and if such
breach shall have continued for a period of three (3) days after the Landlord
shall have given written notice by certified or registered mail to the Tenant at
its office address set forth in Section 1.1. hereof, then, in such event,
Landlord shall have the option to pursue any one or more of the following
remedies:

<PAGE>

15.2.1.  Landlord shall have the right to cancel and terminate this Lease and
dispossess Tenant.

15.2.2.  Landlord shall have the right without terminating or canceling this
Lease to declare all amounts and rents due under this Lease for the remainder of
the existing Lease Tenn (or any applicable extension or renewal thereof) to be
inunediately due and payable, and thereupon all rents and other charges due
hereunder to the end of the initial term or any renewal term, if applicable,
shall be accelerated.

15.2.3.  Landlord may elect to enter and repossess the Premises and relet the
Premises for Tenant's account, holding Tenant liable in damages for all expenses
incurred in any such reletting and for any difference between the amount of rent
received from such relenting and that is due and payable under the terms of this
Lease.

15.2.4.  Landlord may enter upon the Premises and do whatever Tenant is
obligated to do under the temis of this Lease. Tenant agrees to reimburse
Landlord on demand for any expenses which Landlord may incur in effecting
compliance with Tenant's obligations under this Lease and Tenant further agrees
that Landlord shall not be liable for any damages resulting to the Tenant from
such action.

15.2.5.  All such remedies of Landlord shall be cumulative, and, in addition,
Landlord may pursue any other remedies that may be permitted by law or in
equity. Forbearance by Landlord to enforce one or more of the remedies herein
provided upon an event of default shall not be deemed or construed to be a
waiver of such default.

15.2.6.  In addition to the specific remedy or remedies elected by Landlord in
the event of Tenant's default, Landlord shall be entitled to recover from Tenant
all damages incurred by Landlord by reason of Tenant's default, including but
not limited to, the cost of recovering possession of the Premises; expenses of
reletting, including necessary renovations and alterations of the Premises;
reasonable attorneys' fees, and paralegals' fees, costs and expenses, whether or
not in litigation and including at appellate levels and post-judgment
proceedings in litigation; and that portion of the leasing commission paid by
Landlord applicable to the unexpired term of this Lease. Unpaid installments of
rent or other sums shall bear interest from the due date thereof at the maximum
lawful rate.

15.2.7   The remedies provided to Landlord shall be enforceable to the maximum
extent not prohibited by applicable law, and the unenforceability of any portion
hereof shall not thereby render unenforceable any other portion.

15.3. Abandonment of Premises. Landlord and Tenant agree that, for the purposes
of this Lease, abandonment of the Premises shall have occurred if (i) the
Landlord reasonably believes that the Tenant has been absent from the Premises
for a period of thirty (30) consecutive days, and (ii) the Rent is not current
and (iii) ten (IO) days have elapsed since service of a three (3) day notice in
writing by Landlord upon Tenant requiring payment of Rent or the possession of
the Premises.

15.4.    WAIVER OF JURY TRIAL. LANDLORD AND TENANT HEREBY WAIVE TRIAL BY JURY IN
ANY ACTION, PROCEEDING OR COUNTER-CLAM BROUGHT BY EITHER OF THE PARTIES HERETO
AGAINST THE OTHER ON ANY MATTER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS
LEASE.

15.5.    Holdover by Tenant. If Tenant should remain in possession of the
Premises after the expiration of the Lease Tenn, then such holding over shall be
construed as a tenancy at sufferance at an Annual Minimum Rent double that set
forth in Section 1.1. hereof, and subject to all other conditions, provisions
and obligations of this Lease insofar as the same are applicable to a tenancy at
sufferance.

15.6.    Landlord's Right to Cure Defaults. The Landlord may, but shall not be
obligated to, cure at any time, without notice, any default by the Tenant under
this Lease; and, whenever the Landlord so elects, all costs and expenses
incurred by the Landlord in curing such default, including, without limitation,
reasonable attorney's fees, together with interest on the amount of costs and
expenses so incurred at the maximum lawful rate, shall be paid by the Tenant to
the Landlord on demand and shall be recoverable as Additional Rent.

15.7.    Waiver. 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 other or
any subsequent or continuing breach of the same. The subsequent acceptance of
Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding
breach by Tenant of any term, covenant or condition of this Lease, other than
the failure of Tenant to pay the particular rental so accepted, regardless of
Landlord's knowledge of such preceding breach at the time of acceptance of such
Rent.

<PAGE>

15.8.    Intentionally Omitted.

16.      Miscellaneous Provisions.

16.1.    Notice. Any notice or demand from the Landlord to the Tenant or from
the Tenant to the Landlord shall be in writing and shall be deemed duty
delivered if mailed by certified mail, return receipt requested, addressed, if
to the Tenant, at the address of the Tenant or such other address as the Tenant
shall have last designated by written notice to the Landlord; if to the
Landlord, at the address of the Landlord or such other address as the Landlord
shall have last designated by written notice to the Tenant. Notices shall be
deemed delivered when mailed in the manner prescribed above.

16.2.    Estoppel Certificate. The Tenant agrees that it will within ten (10)
days following written notice by the Landlord, execute, acknowledge and deliver

dates to which the Rent and all other payments due hereunder from the Tenant
have been paid, the amount of the Security Deposit then remaining and the amount
of any payments paid by Tenant in advance, and stating whether or not, to the
best knowledge of Tenant, the Landlord is in default in the performance of any
covenant, agreement or condition contained in this Lease and, if so, specifying
each such default. The failure of the Tenant to execute, acknowledge and deliver
to the Landlord a statement in accordance with the provisions of this Section
will constitute a breach of this Lease by the Tenant.

16.3.    Applicable Law and Construction. The laws of the State of Florida shall
govern the validity, performance and enforcement of this Lease. The covenants
and undertakings contained herein are independent, not dependent covenants, and
the invalidity or unenforceability of any provision of this Lease shall not
affect or impair any other provision. All negotiations, considerations,
representations and understandings between the parties are incorporated into
this Lease. The headings of the several articles and sections contained herein
are for convenience and do not define, limit or construe the contents of such
articles or sections.

16.4.    Guaranty. Landlord has advised Tenant, and Tenant acknowledges that
Landlord would not have entered into this Lease or leased the Premises to Tenant
unless one or more principals or affiliates of Tenant execute an Unconditional
Guaranty of Lease in the form attached hereto as Exhibit "D" (the "Guaranty").
Tenant represents and warrants unto Landlord that the party (or parties, as
applicable) executing the Guaranty as Guarantor has a material financial
interest in Tenant and is therefore a principal of Tenant. Tenant further
acknowledges that the obligations of Landlord under this Lease are conditioned
upon the contemporaneous delivery to Landlord of the Guaranty properly executed
by the Guarantor thereunder with this Lease executed on behalf of Tenant.

16.5     Subordination.

16.5.1.  This Lease is subject and subordinate to any ground lease, mortgage,
deed of trust, or any other hypothecation for security now or hereafter placed
upon the Property, and to any and all advances on the security thereof, and to
all renewals, modifications, consolidations, replacements and extensions
thereof. In confirmation of such subordination, the Tenant shall promptly
execute any certificate or Subordination of Lease Agreement that the Landlord
may request to confirm such subordination. The Tenant hereby constitutes and
appoints the Landlord as the Tenant's attomey-in-fact to execute any such
certificate or subordination of lease agreement for and on behalf of the Tenant.

Twelve and 30/100ths Dollars ($31,712.30) as security for the full and faithful
performance of each and every term, provision, covenant and condition of this
Lease. In the event Lessee defaults in respect of any of the terms, provisions,
covenants or conditions of this Lease, including, but not limited to the payment
of rent, Lessor may use, apply or retain the whole or any part of such security
for the payment of any rent in default or for any other sum which Lessor may

to any interest on said security deposit.

Possession

      6. If Lessor, for any reason whatsoever, cannot deliver possession of the
Premises to Lessee at the commencement of the said term, as hereinbefore
specified, this Lease shall not be void or voidable, nor shall Lessor, or
Lessor's agents, be liable to Lessee for any loss or damage resulting therefrom;
but in that event the commencement and termination dates of the Lease and all
other dates affected thereby shall be revised to conform to the date of Lessor's
delivery of possession. The above is, however, subject to the provision that the

termination of this Lease, to surrender the premises, together with all
alterations, additions, and improvements which may have been made in, to, or on
the Premises by Lessor or Lessee, unto Lessor in the same good condition as at
Lessee's entry into the Premises excepting for such wear and tear as would be
normal for the period of the Lessee's occupancy. The Lessee, on or before the
end of the term or sooner termination of this Lease, shall remove all Lessee's
personal property and trade fixtures from the premises and all property not so
removed shall be deemed to

against loss or liability resulting from delay by the Lessee in so surrendering
the Premises including, without limitation, any claims made by any succeeding
tenant founded on such delay. See Addendum Paragraph 103.

Uses Prohibited

      8. Lessee shall not commit, or suffer to be committed, any waste upon the
Premises, or any nuisance, or other act or thing which may disturb the quiet
enjoyment of any other tenant in or around the buildings in which the Premises
may be located, or allow any sale by auction upon the Premises, or allow the
Premises to be used for any improper, immoral, unlawful or objectionable
purpose, or place any loads upon the floor, walls, or roof which endanger the
structure, or place any harmful liquids in the drainage system of the building.
No waste materials or refuse shall be dumped upon or permitted to remain upon
any part of the Premises outside of the building proper. No materials, supplies,
equipment, finished products or semi-finished products, raw materials or
articles of any nature shall be stored upon or permitted to remain on any
portion of the Premises outside of the buildings proper.

Alterations and Additions

      9. The Lessee shall make no alterations, additions or improvements to the
Premises or any part thereof without first obtaining the prior written consent
of the Lessor. Lessor agrees not to unreasonably withhold or delay consent. The
Lessor may impose as a condition to the aforesaid consent such requirements as
Lessor may deem necessary in Lessor's sole discretion, including without
limitation thereto, the manner in which the work is done, a right of approval of
the contractor by whom the work is to be performed, the times during which it is
to be accomplished, and the requirement that upon written request of Lessor
prior to the expiration or earlier termination of the Lease, Lessee will remove
any or all improvements or additions to the Premises installed at Lessee's
expense. All such alterations, additions or improvements not specified to be
removed shall at the expiration or earlier termination of the lease become the
property of the Lessor and remain upon and be surrendered with the Premises. All
movable furniture, business and trade fixtures, and machinery and equipment
shall remain the property of the Lessee and may be removed by the Lessee at any
time during the Lease term when Lessee is not in default hereunder. Items which
are not to be deemed as movable furniture, business and trade fixtures, or
machinery and equipment shall include heating, lighting, electrical systems, air
conditioning, partitioning, carpeting, or any other installation which has
become an integral part of the Premises. The Lessee will at all times permit
notices of non-responsibility to be posted and to remain posted until the

See Addendum Paragraph 104.

Maintenance of Premises

      10. The Lessor will replace the roof covering if repairs to said covering
are no longer economically feasible in the judgment of

<PAGE>

roofing experts, and provided that said replacement is not made necessary by
acts of the Lessee and Lessee's agents. The Lessee shall water, maintain and
replace, when necessary, any shrubbery and landscaping provided by the Lessor on
the Premises. The Lessee expressly waives the benefits of any statute now or
hereafter in effect which would otherwise afford the Lessee the right to make
repairs at Lessor's expense or to terminate this lease because of Lessor's
failure to keep the Premises in good order, condition or repair. See Addendum
Paragraph 105.

Fire and Extended Coverage Insurance and Subrogation

      11. Lessee shall not use, or permit the Premises, or any part thereof, to
be used, for any purposes other than that for which the Premises are hereby
leased; and no use shall be made or permitted to be made on the Premises, nor
acts done, which cause a cancellation of any insurance policy covering said
building, or any part thereof, nor shall Lessee sell or permit to be kept, used,
or sold, in or about the Premises, any article which may be prohibited by the
standard form of fire insurance policies. Lessee shall, at his sole cost and
expense, comply with any and all requirements, pertaining to the Premises, of
any insurance organization or company, necessary for the maintenance of
reasonable fire and public liability insurance, covering said building and
appurtenances.

      11.1 Lessee shall, at its expense, obtain and keep in force during the
term of this Lease a policy of comprehensive public liability insurance insuring
Lessee, Lessor, and any third parties named by Lessor which may include Lessor's
lender, against any liability arising out of the condition, use, occupancy or
maintenance of the Premises. Such insurance policy shall have a combined single
limit for both bodily injury and property damage in an amount of not less than
One Million Dollars ($1,000,000.00). The limits of said insurance shall not
limit the liability of Lessee hereunder.

      11.2 Lessee shall, at its expense, keep in force during the term of this
Lease, a policy of fire and property damage insurance in an "all risk" form with
a sprinkler leakage endorsement, insuring Lessee's inventory, fixtures,
equipment and personal property within the Premises for the full replacement
value thereof.

      11.3 Lessor shall maintain a policy or policies of fire and property
damage insurance in an "all risk" form, with sprinkler and, at the option of the
Lessor, earthquake endorsements, covering loss or damage to the building,
including Lessee's leasehold improvements installed with the written consent of
the Lessor, in such amounts and with such coverage as Lessor deems advisable.

      11.4 Lessee shall pay to Lessor as additional rent, during the term
hereof, upon receipt of an invoice therefore, one hundred percent (100%) of the
premiums for any insurance obtained by Lessor pursuant to 11.3 above. Lessor may
obtain such insurance for the Building separately, or together with other
buildings and improvements which Lessor elects to insure together under blanket
policies of insurance. In such case Lessee shall be liable for only such portion
of the premiums for such blanket policies as are allocable to the Premises. It
is understood and agreed that Lessee's obligation under this

<PAGE>

paragraph shall be prorated to reflect the Commencement Date and Expiration Date
of the Lease.

      11.5 Notwithstanding anything to the contrary contained in this Lease
Lessee and Lessor each hereby waives any and all rights of recovery against the
other, or against the officers, directors, employees, partners, agents and
representatives of the other, for loss or damage to the property of the waiving
party or the property of others under its control, to the extent such loss or
damage is insured against under any insurance policy required to be carried by
Lessor or Lessee hereunder. Each party shall notify their respective insurance
carriers of this waiver.

Abandonment

      12. Lessee shall not vacate or abandon the Premises at any time during the
term; and if Lessee shall abandon, vacate or surrender the premises, or be
dispossessed by process of law, or otherwise, any personal property belonging to
Lessee and left on the Premises shall be deemed to be abandoned, at the option
of Lessor, except such property as may be mortgaged to Lessor.

Free From Liens

      13. Lessee shall keep the Premises and the property in which the Premises
are situated, free from any liens arising out of any work performed, materials
furnished, or obligations incurred by Lessee.

Compliance with Governmental Regulations

      14. Lessee shall, at his sole cost and expense, comply with all of the
requirements of all Municipal, State and Federal authorities now in force, or
which may hereafter be in force (the "Applicable Laws") pertaining to the
Premises, and shall faithfully observe in the use of the Premises all Municipal
ordinances and State and Federal statutes now in force or which may hereafter be
in force. The judgment of any court of competent jurisdiction, or the admission
of Lessee in any action or proceeding against Lessee, whether Lessor be a party
thereto or not, that Lessee has violated any such ordinance or statute in the
use of the Premises, shall be conclusive of that fact as between Lessor and
Lessee. See Addendum Paragraph 106.

Indemnification of Lessor and Lessee's Liability Insurance

      15. The Lessee, as a material part of the consideration to be rendered to
the Lessor, hereby waives all claims against the Lessor for damages to goods,
wares and merchandise, and all other personal property in, upon, or about the
Premises and for injuries to persons in or about the Premises, from any cause
arising at any time, excepting claims arising from negligence or willful
misconduct of Lessor, or Lessor's agents, employees or contractors, and the
Lessee will hold the Lessor exempt and harmless from any damage or injury to any
person, or to the goods, wares and merchandise and all other personal property
of any person, arising from the use of the Premises by the Lessee, or from the
failure of the Lessee to keep the Premises in good condition and repair, as
herein provided, excepting any claims

<PAGE>

arising from the negligence or willful misconduct of Lessor or Lessor's agents,
employees or contractors.

Advertisements and Signs

      16. Lessee will not place or permit to be placed, in, upon or about the
Premises any unusual or extraordinary signs, or any signs not approved by the
city or other governing authority. The Lessee will not place, or permit to be
placed, upon the Premises, any signs, advertisements or notices without the
written consent of the Lessor first had and obtained (which consent will not be
unreasonably withheld or delayed). Any sign so placed on the Premises shall be
so placed upon the understanding and agreement that Lessee will remove same at
the termination of the tenancy herein created and repair any damage or injury to
the Premises caused thereby, and if not so removed by Lessee then Lessor may
have same so removed at Lessee's expense.

Utilities

      17. Lessee shall pay for all water, gas, heat, light, power, telephone
service and all other service supplied to the Premises.

Attorney's Fees

      18. In case suit should be brought for the possession of the Premises, for
the recovery of any sum due hereunder, or because of the breach of any other
covenant herein, the losing party shall pay to the prevailing party a reasonable
attorney's fee, which shall be deemed to have accrued on the commencement of
such action and shall be enforceable whether or not such action is prosecuted to
judgment.

Default

      19. In the event of any breach of this lease by the Lessee, or an
abandonment of the Premises by the Lessee, the Lessor has the option of 1)
removing all persons and property from the Premises and repossessing the
Premises in which case any of the Lessee's property which the Lessor removes
from the Premises may be stored in a public warehouse or elsewhere at the cost
of, and for the account of Lessee, or 2) allowing the Lessee to remain in full
possession and control of the Premises. If the Lessor chooses to repossess the
Premises, the Lease will automatically terminate in accordance with provisions
of the California Civil Code, Section 1951.2. In the event of such termination
of the Lease, the Lessor may recover from the Lessee: 1) the worth at the time
of award of the unpaid rent which had been earned at the time of termination
including interest at(seven percent) 7% per annum; 2) the worth at the time of
award of the amount by which the unpaid rent which would have been earned after
termination until the time of award exceeds the amount of such rental loss that
the Lessee proves could have been reasonably avoided including interest at
(seven percent) 7% per annum; 3) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonable avoided; and 4) any other amount necessary to compensate the Lessor
for all the detriment proximately caused by the Lessee's failure to perform his
obligations under the Lease or which in the ordinary course of things would be
likely to result

<PAGE>

therefrom. If the Lessor chooses not to repossess the premises, but allows the
Lessee to remain in full possession and control of the Premises, then in
accordance with provisions of the California Civil Code, Section 1951.4, the
Lessor may treat the Lease as being in full force and effect, and may collect
from the Lessee all rents as they become due through the termination date of the
lease as specified in the lease. For the purposes of this paragraph, the
following do not constitute a termination of Lessee's right to possession: (a)
Acts of maintenance or preservation or efforts to re-let the property. (b) The
appointment of a receiver on the initiative of the Lessor to protect his
interest under this Lease.

Late Charges

      20. Lessee hereby acknowledges that late payment by Lessee to Lessor of
rent and other sums due hereunder will cause Lessor to incur costs not
contemplated by this lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed on Lessor by the
terms of any mortgage or trust deed covering the Premises. Accordingly, if any
installment of rent or any other sum due from Lessee shall not be received by
Lessor or Lessor's designee within ten (10) days after such amount shall be due,
Lessee shall pay to Lessor a late charge equal to ten percent (10%) of such
overdue amount. The parties hereby agree that such late charge represents a fair
and reasonable estimate of the costs Lessor will incur by reason of late payment
by Lessee. Acceptance of such late charge by Lessor shall in no event constitute
a waiver of Lessee's default with respect to such overdue amount, nor prevent
Lessor from exercising any of the other rights and remedies granted hereunder.

Surrender of Lease

      21. The voluntary or other surrender of this Lease by Lessee, or a mutual
cancellation thereof, shall not work a merger, and shall, at the option of
Lessor, terminate all or any existing subleases or subtenancies, or may, at the
option of Lessor, operate as an assignment to him of any or all such subleases
or subtenancies.

Taxes

      22. The Lessee shall be liable for all taxes levied against personal
property and trade or business fixtures. The Lessee also agrees to pay, as
additional rental, during the term of this Lease and any extensions thereof, all
real estate taxes plus the yearly installments of any special assessments which
are of record or which may become of record during the term of this Lease. If
said taxes and assessments are assessed against the entire building and building
site, and this Lease does not cover the entire building or building site, the
taxes and assessment installments allocated to the Premises shall be pro-rated
on a square footage or other equitable basis, as calculated by the Lessor. It is
understood and agreed that the Lessee's obligation under this paragraph will be
pro-rated to reflect the commencement and termination dates of this Lease.

Notices

<PAGE>

      23. All notices to be given to Lessee shall be given in writing personally
or by depositing the same in the United States mail, postage prepaid, and
addressed to Lessee at the said Premises, whether or not Lessee has departed
from, abandoned or vacated the Premises.

Entry by Lessor

      24. Lessee shall permit Lessor and his agents to enter into and upon the
Premises at all reasonable times after twenty four (24) hour prior written
notice for the purpose of inspecting the same or for the purpose of maintaining
the building in which the Premises are situated, or for the purpose of making
repairs, alterations or additions to any other portion of said building,
including the erection and maintenance of such scaffolding, canopies, fences and
props as may be required without any rebate of rent and without any liability to
Lessee for any loss of occupation or quiet enjoyment of the Premises thereby
occasioned; and shall permit Lessor and his agents, at any time within ninety
(90) days prior to the expiration of this Lease, to place upon the Premises any
usual or ordinary "For Sale" or "To Lease" signs and exhibit the Premises to
prospective tenants at reasonable hours. See Addendum Paragraph 107.

Destruction of Premises

      25. In the event of a partial destruction of the Premises during the said
term from any cause covered by Insurance except earthquake, Lessor shall
forthwith repair the same, provided such repairs can be made within ninety (90)
days under the laws and regulations of State, Federal, County or Municipal
authorities, but such partial destruction shall in no way annul or void this
Lease, except that Lessee shall be entitled to a proportionate reduction of rent
while such repairs are being made, such proportionate reduction to be based upon
the extent to which the making of such repairs shall interfere with the business
carried on by Lessee in the Premises. If such repairs cannot be made in ninety
(90) days, Lessor may, at his option, make same within a reasonable time not to
exceed one hundred eighty (180) days, this Lease continuing in full force and
effect and the rent to be proportionately reduced as aforesaid in this paragraph
provided. In the event that Lessor does not so elect to make such repairs which
cannot be made in ninety (90) days, or such repairs cannot be made under such
laws and regulations within one hundred eighty (180) days, this Lease may be
terminated at the option of either party. In respect to any partial destruction
which Lessor is obligated to repair or may elect to repair under the terms of
this paragraph, the provision of Section 1932, Subdivision 2, and of Section
1933, Subdivision 4, of the Civil Code of the State of California are waived by
Lessee. In the event that the building in which the Premises may be situated be
destroyed to the extent of not less than thirty three and one third percent
(331/3%) of the replacement cost thereof, Lessor may elect to terminate this
Lease, whether the Premises be injured or not. A total destruction of the
building in which the Premises may be situated shall terminate this Lease. In
the event of any dispute between Lessor and Lessee relative to the provisions of
this paragraph, they shall each select an arbitrator, the two arbitrators so
selected shall select a third arbitrator and the three arbitrators so selected
shall hear and determine the controversy and their decision thereon shall be
final and binding upon both Lessor and

<PAGE>

Lessee, who shall bear the cost of such arbitration equally between them.

Assignment and Subletting

      26. The Lessee shall not assign, transfer, or hypothecate the leasehold
estate under this Lease, or any interest therein, and shall not sublet the
Premises, or any part thereof, or any right or privilege appurtenance thereto,
or suffer any other person or entity to occupy or use the Premises, or any
portion thereof, without, in each case, the prior written consent of the Lessor.
Lessor agrees not to unreasonably withhold or delay consent to sublet or assign.
The Lessee shall, by one hundred twenty (120) days written notice, advise the
Lessor of its intent to sublet the Premises or any portion thereof for any part
of the term hereof. Within thirty (30) days after receipt of Lessee's notice,
Lessor shall either give approval to Lessee to sublease the portion of the
Premises described in Lessee's notice, or Lessor shall terminate this Lease as
to the portion of the Premises described in Lessee's notice on the date
specified in Lessee's notice. If Lessee intends to sublet the entire Premises
and Lessor elects to terminate this Lease, this Lease shall be terminated on the
date specified in Lessee's notice. If, however, this Lease shall terminate
pursuant to the foregoing with respect to less than all the Premises, the rent,
as defined and reserved hereinabove shall be adjusted on a prorata basis to the
number of square feet retained by Lessee, and this Lease as so amended shall
continue in full force and effect. If the Lessor approves a subletting, the
Lessee may sublet immediately after receipt of the Lessor's written approval. In
the event Lessee is allowed to assign, transfer or sublet the whole or any part
of the Premises, with the prior written consent of Lessor, no assignee,
transferee or sublessee shall assign or transfer this Lease, either in whole or
in part, or sublet the whole or any part of the Premises, without also having
obtained the prior written consent of the Lessor. A consent of Lessor to one
assignment, transfer, hypothecation, subletting, occupation or use by any other
person shall not release Lessee from any of Lessee's obligations hereunder or be
deemed to be a consent to any subsequent similar or dissimilar assignment,
transfer, hypothecation, subletting, occupation or use by any other person. Any
such assignment, transfer, hypothecation, subletting, occupation or use without
such consent shall be void and shall constitute a breach of this Lease by Lessee
and shall, at the option of Lessor exercised by written notice to Lessee,
terminate this Lease. The leasehold estate under this Lease shall not, nor shall
any interest therein, be assignable for any purpose by operation of law without
the written consent of Lessor. As a condition to its consent, Lessor may require
Lessee to pay all expense in connection with the assignment, and Lessor may
require Lessee's assignee or transferee (or other assignees or transferees) to
assume in writing all of the obligations under this Lease. See Addendum
Paragraph 108.

Condemnation

      27. If any part of the premises shall be taken for any public or
quasi-public use, under any statute or by right of eminent domain or private
purchase in lieu thereof, and a part thereof remains which is susceptible of
occupation hereunder, this Lease shall, as to the part so taken, terminate as of
the date title shall vest in the condemner

<PAGE>

or purchaser, and the rent payable hereunder shall be adjusted so that the
Lessee shall be required to pay for the remainder of the term only such portion
of such rent as the value of the part remaining after such taking bears to the
value of the entire Premises prior to such taking; but in such event Lessor
shall have the option to terminate this Lease as of the date when title to the
part so taken vests in the condemner or purchaser. If all of the premises, or
such part thereof be taken so that there does not remain a portion susceptible
for occupation hereunder, this Lease shall thereupon terminate. If a part of all
of the Premises be taken, all compensation awarded upon such taking shall go to
the Lessor and Lessee shall have no claim thereto.

Effect of Conveyance

      28. The term "Lessor" as used in this Lease, means only the owner for the
time being of the land and building containing the Premises, so that, in the
event of any sale of said land or building, or in the event of a lease of said
building, the Lessor shall be and hereby is entirely freed and relieved of all
covenants and obligations of the Lessor hereunder to the extent that they
pertain to the period of time on or after the effective date of such transfer
and it shall be deemed and construed, without further agreement between the
parties and the purchaser at any such sale, or the Lessee of the building, that
the purchaser or lessee of the building has assumed and agreed to carry out any
and all covenants and obligations of the Lessor hereunder. If any security be
given by the Lessee to secure the faithful performance of all or any of the
covenants of this Lease on the part of the Lessee, the Lessor may transfer and
deliver the security, as such, to the purchaser at any such sale or the lessee
of the building, and thereupon the Lessor shall be discharged from any further
liability in reference thereto.

Subordination

      29. Lessee agrees that this Lease may, at the option of Lessor, be subject
and subordinate to any mortgage, deed of trust or other instrument of security
which has been or shall be placed on the land and building or land or building
of which the Premises form a part, and this subordination is hereby made
effective without any further act of Lessee. The Lessee shall, at any time
hereinafter, on demand, execute any instruments, releases, or other documents
that may be required by any mortgagee, mortgagor, or trustor or beneficiary
under any deed of trust for the purpose of subjecting and subordinating this
Lease to the lien of any such mortgage, deed of trust or other instrument of
security, and the failure of the Lessee to execute any such instruments,
releases or documents, shall constitute a default hereunder. See Addendum
Paragraph 109.

Waiver

      30. The waiver by either Lessor or Lessee of any breach of any term,
covenant or condition, herein contained shall not be deemed to be a waiver of
such term, covenant or condition or any subsequent breach of the same or any
other term, covenant or condition therein contained. The subsequent acceptance
of rent hereunder by Lessor shall not be deemed to be a waiver of any preceding
breach by Lessee of any term, covenant or condition of this Lease, other than
the

<PAGE>

failure of Lessee to pay the particular rental so accepted, regardless of
Lessor's knowledge of such preceding breach at the time of acceptance of such
rent.

Holding Over

      31. Any holding over after the expiration of the said term, with the
consent of Lessor, shall be construed to be a tenancy from month to month, at a
rental to be negotiated by Lessor and Lessee prior to the expiration of said
term, and shall otherwise be on the terms and conditions herein specified, so
far as applicable.

Successors and Assigns

      32. The covenants and conditions herein contained shall, subject to the
provisions as to assignment, apply to and bind the heirs, successors, executors,
administrators and assigns of all of the parties hereto; and all of the parties
hereto shall be jointly and severally liable hereunder.

Time

      33. Time is of the essence of this Lease.

Marginal Captions

      34. The marginal headings or titles to the paragraphs of this Lease are
not a part of this Lease and shall have no effect upon the construction or
interpretation of any part thereof. This instrument contains all of the
agreements and conditions made between the parties hereto and may not be
modified orally or in any other manner than by an agreement in writing signed by
all of the parties hereto or their respective successors in interest. See
Addendum Paragraphs 110 and 111.

                                ADDENDUM TO LEASE

This Addendum to Lease ("Addendum") shall add the following provisions to the
Lease between Raymond G. Handley ("Lessor"), and Drexler Technology Corporation,
a Delaware corporation ("Lessee") dated February 16, 2000 (the "Lease"). The
term "this Lease" when used herein shall mean the Lease as modified by this
Addendum. All capitalized terms not defined in this Addendum shall have the
meanings given in the Lease. If the terms of this Addendum conflict with the
other terms of the Lease, the terms of this Addendum shall prevail and be
controlling.

            102. Early Occupancy. This Lease, effective May 1, 2000, supersedes
the lease between Lessor and Lessee dated January 28, 1999 for the approximate
5,038 square foot portion of the Premises demised under this Lease and upon
execution hereof, Lessor and Lessee hereby acknowledge that the above referenced
lease is surrendered. Notwithstanding the foregoing, Lessor shall allow Lessee
to occupy the entire Building commencing March 1, 2000 so that Lessee may design
and construct alterations and improvements as necessary. Such early occupancy
shall be on all the terms and conditions of this Lease excepting that the
monthly rental for March and April of 2000 shall be Nine Thousand Three Hundred
Forty and No/100ths Dollars ($9,340.00). Lessee's design and construction of
improvements and alterations shall be subject to the terms contained in
Paragraph 9 of this Lease and Paragraph 104 of this Addendum.

            103. Acceptance of Premises and Consent to Surrender. The following
provision is added to the end of Section 7 of the Lease:

      Notwithstanding anything to the contrary contained in Paragraph 7 of the
      Lease, Lessee hereby Leases the Premises from Lessor in "as is", "where
      is" condition and Lessor shall only be obligated to deliver to Lessee that
      portion of the Premises which is not currently occupied by Lessee in broom
      clean condition with the roof covering, HVAC, plumbing and electrical
      systems (collectively, the "Building Systems") in good working order and
      repair, damaged ceiling tiles replaced, fluorescent light fixtures
      revamped and the tile flooring in the area indicated on Exhibit A removed.
      Lessee shall be solely responsible for all costs of any improvements or
      alterations and Lessor shall have no obligation to contribute toward the
      cost of any improvements or alterations whatsoever. If Lessee gives Lessor
      written notice within such thirty (30) day period that the Building
      Systems were not found in good and satisfactory condition, then promptly
      after receiving such notice Lessor shall cause the same to be corrected at
      its own expense without right to reimbursement from Lessee.

            104. Alterations and Additions. The following provision is added to
the end of Section 9 of the Lease:

<PAGE>

      Notwithstanding anything to the contrary in this Lease, at the time Lessor
      grants its consent to any alterations, additions or improvements, Lessor
      shall notify Lessee whether or not Lessor will require Lessee to remove
      such alterations, additions or improvements at the end of the Lease term.

            105. Maintenance of the Premises. The following provision is added
to the beginning of Section 10 of the Lease:

      Lessee shall, at Lessee's cost, keep and maintain the interior of the
      Premises, including but not limited to, glazing, plumbing, electrical
      systems, any store front, roof covering - unless it is not feasible to
      repair the existing roof covering and a new roof covering is required, in
      good order, condition and repair. Lessor, at Lessor's sole cost and
      expense, shall maintain the exterior of the walls, and structural portions
      of the roof, foundations and floors except for any repairs caused by the
      wrongful act of the Lessee and Lessee's agents. The Lessor will replace
      the roof covering if repairs to said covering are no longer economically
      feasible in the judgment of roofing experts and provided that said
      replacement is not made necessary by acts of the Lessee or Lessee's
      agents. The Lessee shall maintain heating and air conditioning
      installations. Costs or expenses which are incurred by Lessor that
      according to generally accepted accounting principles are required to be
      capitalized, shall be reimbursable by Lessee only on an amortized basis
      over the useful life of the improvement; provided, however, Lessee shall
      have no obligation to reimburse Lessor for the cost of repairs or
      replacements to the heating and air conditioning installations or roof
      covering required during the first twelve (12) months of the Lease term,
      or if the need for such repair or replacement is caused by the negligence
      or willful misconduct of Lessor or Lessor's agents, employees, or
      contractors, or other tenants of the Building.

            106. Compliance with Governmental Regulations. The following
provision is added to the end of Section 14 of the Lease:

      Notwithstanding the foregoing, Lessee shall be responsible for bringing
      the Premises into compliance with Applicable Laws only to the extent that
      such compliance is "triggered" by Lessee's unique and particular use of
      the Premises and by Lessee's construction of interior improvements.

            107. Entry of Lessor. The following provision is added to the end of
Section 24 of the Lease:

      Any work performed by Lessor pursuant to this Section shall be done in a
      manner which causes the least amount of inconvenience and interference to
      Lessee's use of the Premises and the common areas as reasonably possible.

            108. Assignment and Subletting. The following provision is added
after the first sentence of Section 26 of the Lease:

      As a condition for granting its consent of any subletting, the Lessor
      shall require the Lessee to agree to pay to Lessor, as

<PAGE>

      additional rental fifty percent (50%) of all rent received by the Lessee
      from its Sublessee which are in excess of the amount payable by Lessee to
      Lessor hereunder, provided, however, in calculating the sums in excess of
      rent payable by Lessee to Lessor, Lessee shall first be entitled to
      recover (i) reasonable leasing commissions paid to third parties in order
      to obtain the assignment or subletting in question, (ii) reasonable
      attorney's fees paid by Lessee with respect to the assignment or
      subletting in question, and (iii) the unamortized cost of Lessee's
      improvements and alterations.

The following provision is added to the end of Section 26 of the Lease.

      Lessor's prior consent shall not be required for any assignment, sublease
      or other transfer of Lessee's interest in the Premises or the Lease to any
      corporation with which Lessee may merge or consolidate or become
      affiliated as a parent, subsidiary, holding company or otherwise, or to an
      entity in which Lessee has a controlling interest.

            109. Subordination. The following provision shall be added to the
end of Section 29 of the Lease.

      Notwithstanding anything to the contrary in this Section 29 of the Lease,
      any such subordination shall not provide for or permit a termination of
      this Lease by any party or under any circumstances so long as Lessee is
      not in default under the terms of this Lease beyond any applicable cure
      period.

            110. Hazardous Materials. Lessor agrees that Lessee shall have no
liability or responsibility whatsoever for any Hazardous Material on or about
the Premises, the Building, or the related common areas which were not created
by Lessee, or Lessee's agents, employees, contractors, or affiliates. Lessor
shall indemnify, defend and hold Lessee harmless against all claims, losses,
costs or liabilities arising out of or related to testing for, or the presence,
use, storage, disposal, removal, remediation or clean-up of any Hazardous
Material in or about the Premises, the Building or the common areas, unless
caused by, contributed to, or created by Lessee. As used herein, the term
"Hazardous Material" shall mean any hazardous or toxic substance, material or
waste which is or becomes regulated by any state, federal, local government
authority, including asbestos and all of those materials and substances
designated as hazardous or toxic by the Environmental Protection Agency, the
California Water Quality Control Board, the Department of Labor, the California
Department of Industrial Relations, the Department of Transportation, the
Department of Agriculture, the Department of Health Services or the Food and
Drug Agency.

            111. Option to Extend. Subject to the conditions below, Lessee shall
have the option(s) to extend the term of this Lease for one (1) period of five
(5) years (the "Extension Term"), which Extension Term shall commence upon the
expiration of the previous term. Lessee shall give Lessor notice of the exercise
of its option at least six (6) months but not more than nine (9) months prior to
the expiration of the then current term. The Extension Term shall be upon

<PAGE>

the same terms and conditions as contained in the Lease, except that the Rent
shall be determined in accordance with the procedure set forth below. If Lessee
has exercised its option to extend, the phrase "Lease Term" as used in the Lease
shall mean the initial term of the lease and the Extension Term.

            Rent for the Option Term shall be at fair market rental value,
determined as follows:

      (i)   Lessor shall deliver to Lessee written notice of Lessor's
            determination of fair market rental value within thirty (30) days
            after Lessor receives notice from Lessee that Lessee has exercised
            its option to extend.

      (ii)  If Lessee disputes Lessor's determination of the fair market rental
            value as contained in Lessor's notice, Lessee shall notify Lessor in
            writing within ten (10) days of its receipt of Lessor's
            determination, which notice shall set forth Lessee's determination
            of the fair market rental value. Should Lessee timely notify Lessor
            as aforesaid, Lessor and Lessee shall attempt to resolve their
            differences within ten (10) days following Lessor's receipt to
            Lessee's notice.

      (iii) If Lessor and Lessee cannot agree on fair market rental value during
            such ten (10) day period, Lessor and Lessee shall each appoint a
            disinterested real estate broker experienced in leasing similar
            space in the county in which the Premises are located and give
            notice of such appointment to the other within ten (10) days after
            the preceding ten (10) day period. If either Lessor or Lessee shall
            fail timely to appoint a broker, then the single broker appointed by
            one party shall proceed to make the determination of fair market
            rental value. Such broker(s) shall, within thirty (30) days after
            the appointment of the last of them to be appointed, complete their
            written determinations of fair market rental value and furnish the
            same to Lessor and Lessee. Each party shall pay the fees and costs
            of the broker appointed by it. If the valuations vary by ten percent
            (10%) or less of the higher value, the fair market rental value
            shall be the average of the two variations.

      (iv)  If the valuations vary by more than ten percent (10%) of the higher
            value, the two brokers shall, within ten (10) days after submission
            of the last appraisal report, appoint a third disinterested broker.
            Such third broker shall, within thirty (30) days after appointment,
            select one of the two valuations submitted by the first two brokers
            as such third broker's determination of fair market value, and shall
            submit such decision to Lessor and Lessee. The fair market rental
            value of the Premises as determined by the third broker shall be
            controlling. All fees and costs incurred in connection with the
            determination of fair market rental value by the third broker shall
            be paid one-half by Lessor and one-half by Lessee.

<PAGE>

      (v)   For purposes of this Paragraph, the fair market rental value of the
            Premises shall take into consideration all current market factors,
