                  (xi)  If Tenant fails to maintain the Premises, any expense

Tenant.

            (c)   The inclusion of the improvements, facilities and services set

Base Rent is due Tenant's Share of estimated Operating Expenses and other

detailed statement showing Tenant's Share of the actual Operating Expenses

said statement, Tenant shall be credited the amount of such overpayment against
Tenant's Share of Operating Expenses next becoming due. If Tenant's estimated
payments under this Paragraph 4.2(d) during said preceding year were less than
Tenant's Share as indicated on said statement, Tenant shall pay to Landlord the
amount of the deficiency within 10 days after delivery by Landlord to tenant of
said statement. At any time Landlord may adjust the amount of the estimated
Tenant's Share of Operating Expenses and HVAC maintenance costs to reflect
Landlord's estimate of such expenses for the year.

Operating Expenses, Real Property Taxes, Landlord Insurance and other charges
payable by Tenant under this Lease, Landlord shall be liable for the payment of
the Florida sales and use tax and all other taxes of any kind which may be
imposed upon the rentals and other charges payable hereunder. Tenant shall pay
all such taxes to Landlord monthly together with each and every payment of the
Base Rent and other charges payable hereunder, and Landlord shall remit said
amount to the appropriate taxing authority.

5.    SECURITY DEPOSIT. Tenant shall deposit with Landlord upon Tenant's
execution hereof the Security Deposit set forth in Paragraph 1.7 as security for
Tenant's faithful performance of Tenants obligations under this Lease. If Tenant
fails to pay Base Rent or Additional Rent or otherwise defaults under this Lease
(as defined in Paragraph 13.1), Landlord may use the Security Deposit for the
payment of any amount due Landlord or to reimburse or compensate Landlord for
any liability, cost, expense, loss or damage (including attorney's fees) which
Landlord may suffer or incur by reason thereof. Tenant shall on demand pay
Landlord the amount so used or applied so as to restore the Security Deposit to
the amount set forth in Paragraph 1.7. Landlord shall not be required to keep
all or any part of the Security Deposit separate from its general accounts.
Landlord shall, at the expiration or earlier termination of the term hereof and
after Tenant has vacated the Premises, return to Tenant that portion of the
Security Deposit not used or applied by Landlord. No part of the Security
Deposit shall be considered to be held in trust, to bear interest, or to be
prepayment for any monies to be paid by Tenant under this Lease. The acceptance
by Landlord of the Security Deposit paid by Tenant shall not render this Lease
effective unless and until Landlord shall have executed and delivered to Tenant
a fully executed copy of this Lease. In the event of a sale of the Building,
Landlord shall have the right to transfer the Security Deposit to the purchaser,
and upon acceptance by such purchaser, Landlord shall be released from all
liability for the return of the Security Deposit. Tenant shall not assign or
encumber the money deposited as security, and neither Landlord nor its
successors or assigns shall be bound by any such assignment or encumbrance.

Permitted Use set forth in Paragraph 1.8. Tenant shall not commit any nuisance,

invalidate or increase the premiums for any of Landlord's insurance. Tenant
shall not service, maintain or repair vehicles on the Premises, Building or
Common Areas. Tenant shall not store foods, pallets, drums or any other
materials outside the Premises. Landlord makes no (and does hereby expressly
disclaim any) covenant, representation or warranty as to the Permitted Use being

restrictive covenants now or hereafter affecting the Premises, and any zoning
letters, copies of zoning ordinances or other information from any governmental
agency or other third party provided to Tenant by Landlord or any of Landlord's

expressly acknowledging and agreeing that Tenant shall conduct and rely solely
on its own due diligence and investigation with respect to the compliance of the

covenants and not on any such information provided by Landlord or any of its
agents or employees.

<PAGE>

            (a)   Reportable Uses Require Consent. The term "Hazardous
Substance" as used in this Lease shall mean any product, substance, chemical,
material or waste whose presence, nature, quantity and/or intensity of
existence, use, manufacture, disposal, transportation, spill, release or effect,
either by itself or in combination with other materials expected to be on the
Premises, is either: (i) potentially injurious to the public health, safety or
welfare, the environment, or the Premises; (ii) regulated or monitored by any
governmental authority; or (iii) a basis for potential liability of Landlord to
any governmental agency or third party under any applicable statute or common
law theory. Hazardous Substance shall include, but not be limited to,

thereof. Tenant shall not engage in any activity in or about the Premises which
constitutes a Reportable Use (as hereinafter defined) of Hazardous Substances
without the express prior written consent of Landlord and compliance in a timely
manner (at Tenant's sole cost and expense) with all Applicable Requirements (as
defined in Paragraph 6.3), "Reportable Use" shall mean (i) the installation or
use of any above or below ground storage tank, (ii) the generation, possession,

respect to which any Applicable Requirements require that a notice be given to
persons entering or occupying the Premises or neighboring properties.
Notwithstanding the foregoing, Tenant may, without Landlord's prior consent, but
upon notice to Landlord and in compliance with all Applicable Requirements, use
any ordinary and customary materials reasonably required to be used by Tenant in
the normal course of the Permitted Use, so long as such use is not a Reportable
Use and does not expose the Premises, or neighboring properties to any
meaningful risk of contamination or damage or expose Landlord to any liability
therefor. In addition, Landlord may (but without any obligation to do so)
condition its consent to any Reportable Use of any Hazardous Substance by Tenant
upon Tenant's giving Landlord such additional assurances as Landlord, in its
reasonable discretion, deems necessary to protect itself, the public, the
Premises and the environment against damage, contamination or injury and/or
liability therefor, including but not limited to the installation (and, at
Landlord's option, removal on or before Lease expiration or earlier termination)
of reasonably necessary protective modifications to the Premises (such as
concrete encasements) and/or the deposit of an additional Security Deposit.
Tenant acknowledges (i) completion of Environmental and Use Questionnaire
(Exhibit C) and (ii) Landlord's reliance upon same as a material inducement to
enter into the Lease.

            (b)   Duty to Inform Landlord. If Tenant knows, or has reasonable
cause to believe, that a Hazardous Substance is located in, under or about the
Premises or the Building, Tenant shall immediately give Landlord written notice
thereof, together with a copy of any statement, report, notice, registration,
application, permit, business plan, license, claim, action, or proceeding given
to, or received from, any governmental authority or private party concerning the
presence, spill, release, discharge of, or exposure to, such Hazardous
Substance. Tenant shall not cause or permit any Hazardous Substance to be
spilled or released in, on, under or about the Premises (including, without
limitation, through the plumbing or sanitary sewer system).

            (c)   Indemnification. Tenant shall indemnify, protect, defend and
hold Landlord, Landlord's affiliates, Lenders, and the officers, directors,
shareholders, partners, employees, managers, independent contractors, attorneys
and agents of the foregoing ("Landlord Entities") and the Premises, harmless
from and against any and all damages, liabilities, judgments, costs, claims,
liens, expenses, penalties, loss of permits and attorneys' and consultants' fees
arising out of or involving any Hazardous Substance brought onto the Premises by
or for Tenant or by any of Tenant's employees, agents, contractors or invitees.
Tenant's obligations under this Paragraph 6.2(c) shall include, but not be
limited to, the effects of any contamination or injury to person, property or
the environment created or suffered by Tenant, and the cost of investigation
(including consultants' and attorneys' fees and testing), removal, remediation,
restoration and/or abatement thereof, or of any contamination therein involved.
Tenant's obligations under this Paragraph 6.2(c) shall survive the expiration or
earlier termination of this Lease.

      6.3   Tenant's Compliance with Requirements. Tenant shall, at Tenant's
sole cost and expense, fully, diligently and in a timely manner, comply with all
"Applicable Requirements," which term is used in this Lease to mean all laws,
rules, regulations, ordinances, directives, covenants, easements and
restrictions of record, permits, the requirements of any applicable fire
insurance underwriter or rating bureau, and the recommendations of Landlord's
engineers and/or consultants, relating in any manner to the Premises (including
but not limited to matters pertaining to (i) industrial hygiene, (ii)
environmental conditions on, in, under or about the Premises, including soil and
groundwater conditions, and (iii) the use, generation, manufacture, production,
installation, maintenance, removal, transportation, storage, spill or release of
any Hazardous Substance), now in effect or which may hereafter come into effect.
Tenant shall, within 5 days after receipt of Landlord's written request, provide
Landlord with copies of all documents and information evidencing Tenant's
compliance with any Applicable Requirements and shall immediately upon receipt,
notify Landlord in writing (with copies of any documents involved) of any
threatened or actual claim, notice, citation, warning, complaint or report
pertaining to or involving failure by Tenant or the Premises to comply with any
Applicable Requirements.

      6.4   Inspection: Compliance with Law. In addition to Landlord's
environmental monitoring and insurance program, the cost of which is included in
Operating Expenses, Landlord and the holders of any mortgages, deeds of trust or
ground leases on the Premises ("Lenders") shall have the right to enter the
Premises at any time in the case of an emergency, and otherwise at reasonable
times, for the purpose of inspecting the condition of the Premises and for
verifying compliance by Tenant with this Lease and all Applicable Requirements.
Landlord shall be entitled to employ experts and/or consultants in connection
therewith to advise Landlord with respect to Tenant's installation, operation,
use, monitoring, maintenance, or removal of any Hazardous Substance on or from
the Premises. The cost and expenses of any such inspections shall be paid by the
party requesting same unless a violation of Applicable Requirements exists or is
imminent or the inspection is requested or ordered by a governmental authority.
In such case, Tenant shall upon request reimburse Landlord or Landlord's Lender,
as the case may be, for the costs and expenses of such inspections.

7.    MAINTENANCE, REPAIRS, TRADE FIXTURES AND ALTERATIONS.

      7.1   Tenant's Obligations. Subject to the provisions of Paragraph 7.2
(Landlord's Obligations), Paragraph 9 (Damage or Destruction) and Paragraph 14
(Condemnation), Tenant shall, at Tenant's sole cost and expense and at all
times, keep the Premises and every part thereof in good order, condition and
repair (whether or not such portion of the Premises requiring repair, or the
means of repairing the same, are reasonable or readily accessible to Tenant and
whether or not the need for such repairs occurs as a result of Tenant's use, any
prior use, the elements or the age of such portion of the Premises) including,
without limiting the generality of the foregoing, all equipment or facilities
specifically serving the Premises, such as plumbing, heating, air conditioning,
ventilating, electrical, lighting facilities, boilers, fired or unfired pressure
vessels, fire hose connectors if within the Premises, fixtures, interior walls,
interior surfaces of exterior walls, ceilings, floors, windows, doors, plate
glass, and skylights, but excluding any items which are the responsibility of
Landlord pursuant to Paragraph 7.2 below. Tenant's obligations shall include
restorations, replacements or renewals when necessary to keep the Premises and
all improvements thereon or a part thereof in good order, condition and state of
repair.

      7.2   Landlord's Obligations. Subject to the provisions of Paragraph 6
(Use), Paragraph 7.1 (Tenant's Obligations), Paragraph 9 (Damage or Destruction)
and Paragraph 14 (Condemnation), Landlord at its expense and not subject to

repair the foundations and exterior walls of the Building and utility systems
outside the Building. Landlord, subject to reimbursement pursuant to Paragraph
4.2, shall keep in good order, condition and repair the air conditioning systems
servicing the Premises, Building roof and Common Areas.

      7.3   Alterations. Tenant shall not make nor cause to be made any
alterations, installations in, on, under or about the Premises. Nothing in this
Lease shall be deemed to be, or construed in any way as constituting, the
consent or request of Landlord, expressed or implied, by inference or otherwise,
to any person, firm or corporation for the performance of any labor or the
furnishing of any materials for any construction, rebuilding, alteration or
repair of or to the Premises or any part thereof, nor as giving Tenant any
right, power or authority to contract for or permit the rendering of any
services or the furnishing of any materials which might in any way give rise to
the right to file any lien against Landlord's interest in the Premises. Landlord
shall have the right to post and keep posted at all reasonable times on the
Premises any notices which Landlord shall be required so to post for the
protection of Landlord and the Demised Premises from any such lien. Tenant
agrees to promptly execute such instruments in recordable form in accordance
with the terms and provisions of Section 713.10, Florida Statutes, as are
necessary to give public notice of the terms and conditions hereof. Tenant is
hereby informed that Landlord may have already filed a notice in the public
records which precludes the Landlord's interest in Building from being subject
to the liens of contractors performing work for Tenant.

      7.4   Surrender/Restoration. Tenant shall surrender the Premises by the
end of the last day of the Lease term or any earlier termination date, clean and
free of debris and in good operating order, condition and state of repair,
ordinary wear and tear excepted. Without limiting the generality of the above,
Tenant shall remove all personal property, trade fixtures and floor bolts, patch
all floors and cause all lights to be in good operating condition.

8.    INSURANCE; INDEMNITY.

      8.1   Payment of Premiums. The cost of the premiums for the insurance
policies maintained by Landlord under this Paragraph 8 shall be a Common Area
Operating Expense pursuant to Paragraph 4.2 hereof. Premiums for policy periods
commencing prior to, or extending beyond, the term of this Lease shall be
prorated to coincide with the corresponding Commencement Date of Expiration
Date.

      8.2   Tenant's Insurance.

      (a)   At its sole cost and expense, Tenant shall maintain in full force
and effect during the Term of the lease the following insurance coverages
insuring against claims which may arise from or in connection with the Tenant's
operation and use of the leased premises.

            (i)   Commercial General Liability with minimum limits of $1,000,000

vehicles with a $1,000,000 per accident limit for bodily injury and property
damage.

            (iv)  Property insurance against all risks of loss to any tenant
improvements or betterments and business personal property on a full replacement
cost basis with no coinsurance penalty provision; and Business Interruption
Insurance with a limit of liability representing loss of at least approximately
six months of income.

      (b)   Tenant shall deliver to AMB certificates of all insurance reflecting
evidence of required coverages prior to initial occupancy; and annually
thereafter.

      (c)   If, in the opinion of Landlord's insurance advisor, the amount or
scope of such coverage is deemed inadequate at any time during the Term, Tenant
shall increase such coverage to such reasonable amounts or scope as Landlord's

      (d)   All insurance required under Paragraph 8.2 (a) shall (i) be primary
and non-contributory; (ii) provide for severability of interests, (iii) be
issued by insurers, licensed to do business in the state in which the Premises
are located and which are rated A:VII or better by Best's Key Rating Guide, (iv)
be endorsed to include Landlord and such other persons or entities as Landlord
may from time to time designate, as additional insureds (Commercial General
Liability only), and (v) be endorsed to provide at least 30-days prior
notification of cancellation or material change in coverage to said additional
insureds.

      8.3   Landlord's Insurance. Landlord may, but shall not be obligated to,
maintain all risk, including earthquake and flood, insurance covering the
buildings within the Industrial Center, Commercial General Liability and such
other insurance in such amounts and covering such other liability or hazards as
deemed appropriate by Landlord. The amount and scope of coverage of Landlord's
insurance shall be determined by Landlord from time to time in its sole
discretion and shall be subject to such deductible amounts as Landlord may
elect. Landlord shall have the right to reduce or terminate any insurance or
coverage. Premiums for any such insurance shall be a Common Area Operating
Expense.

      8.4   Waiver of Subrogation. To the extent permitted by law and without
affecting the coverage provided by insurance required to be maintained
hereunder, Landlord and Tenant each waive any right to recover against the other
on account of any and all claims Landlord or Tenant may have against the other
with respect to property insurance actually carried, or required to be carried
hereunder, to the extent of the proceeds realized from such insurance coverage.

      8.5   Indemnity. Tenant shall protect, indemnify and hold the Landlord
Entities harmless from and against any and all loss, claims, liability or costs
(including court costs and attorney's fees) incurred by reason of:

            (a)   any damage to any property (including but not limited to
property of any Landlord Entity) or death or injury to any person occurring in
or about the Premises, the Building or the Industrial Center to the extent that
such injury or damage shall be caused by or arise from any actual or alleged
act, neglect, fault or omission by or of Tenant, its agents, servants,
employees, invitees, or visitors;

            (b)   the conduct or management of any work or anything whatsoever
done by the Tenant on or about the Premises or from transactions of the Tenant
concerning the Premises;

            (c)   Tenant's failure to comply with any and all governmental laws,
ordinances and regulations applicable to the condition or use of the Premises or
its occupancy; or

            (d)   any breach or default of the part of Tenant in the performance
of any covenant or agreement on the part of the Tenant to be performed pursuant
to this Lease.

The provisions of this Paragraph 8.5 shall survive the termination of this Lease
with respect to any claims or liability accruing prior to such termination.

      8.6   Exemption of Landlord from Liability. Except to the extent caused by
the gross negligence or willful misconduct of Landlord, Landlord Entities shall
not be liable for and Tenant waives any claims against Landlord Entities for
injury or damage to the person or the property of Tenant, Tenant's employees,
contractors, invitees, customers or any other person in or about the Premises,
Building or Industrial Center from any cause whatsoever, including, but not
limited to, damage or injury which is caused by or results from (i) fire, steam,
electricity, gas, water or rain, or from the breakage, leakage, obstruction or
other defects of pipes, fire sprinklers, wires, appliances, plumbing, air
conditioning or lighting fixtures or (ii) from the condition of the Premises,
other portions of the Building or Industrial Center. Landlord shall not be
liable for any damages arising from any act or neglect of any other tenant of
Landlord nor from the failure by Landlord to enforce the provisions of any other
lease in the Industrial Center. Notwithstanding Landlord's negligence or breach
of this Lease, Landlord shall under no circumstances be liable for injury to
Tenant's business, for any loss of income or profit therefrom or any indirect,
consequential or punitive damages.

9.    DAMAGE OR DESTRUCTION.

      9.1   Termination Right. Tenant shall give Landlord immediate written
notice of any damage to the Premises. Subject to the provisions of Paragraph
9.2, if the Premises or the Building shall be damaged to such an extent that
there is substantial interference for a period exceeding 90 consecutive days
with the conduct by Tenant of its business at the Premises, Tenant, at any time
prior to commencement of repair of the Premises and following 10 days written
notice to Landlord, may terminate this Lease effective 30 days after delivery of
such notice to Landlord. Such termination shall not excuse the performance by
Tenant of those covenants, which under the terms hereof survive termination.
Rent shall be abated in proportion to the degree of interference during the
period that there is such substantial interference with the conduct of Tenant's
business at the Premises. Abatement of rent and Tenant's right of termination
pursuant to this provision shall be Tenant's sole remedy for failure of Landlord
to keep in good order, condition and repair the foundations and exterior walls
of the Building, Building roof, utility systems outside the Building, the Common
Areas and HVAC.

      9.2   Damage Caused by Tenant. Tenant's termination rights under Paragraph
9.1 shall not apply if the damage to the Premises or Building is the result of
any act or omission of Tenant or of any of Tenant's agents, employees,
customers, invitees or contractors ("Tenant Acts"). Any damage resulting from a
Tenant Act shall be promptly repaired by Tenant. Landlord at its option may at
Tenant's expense repair any damage caused by Tenant Acts. Tenant shall continue
to pay all rent and other sums due hereunder and shall be liable to Landlord for
all damages that Landlord may sustain resulting from a Tenant Act.

10.   REAL PROPERTY TAXES.

      10.1  Payment of Real Property Taxes. Landlord shall pay the Real Property
Taxes due and payable during the term of this Lease and, except as otherwise
provided in Paragraph 10.3, any such amounts shall be included in the
calculation of Operating Expenses in accordance with the provisions of Paragraph
4.2.

      10.2  Real Property Tax Definition. As used herein, the term "Real
Property Taxes" is any form of tax or assessment, general, special, ordinary or
extraordinary, imposed or levied upon (a) the Industrial Center, (b) any
interest of Landlord in the Industrial Center, (c) Landlord's right to rent or
other income from the Industrial Center, and/or (d) Landlord's business of
leasing the Premises. Real Property Taxes include (i) any license fee,
commercial rental tax, excise tax, improvement bond or bonds, levy or tax; (ii)
any tax or charge which replaces or is in addition to any of such
above-described "Real Property Taxes" and (iii) any fees, expenses or costs
(including attorney's fees, expert fees and the like) incurred by Landlord in
protesting or contesting any assessments levied or any tax rate. The term "Real
Property Taxes" shall also include any increase resulting from a change in the
ownership of the Industrial Center or Building, the execution of this Lease or
any modification, amendment or transfer thereof. Real Property Taxes for tax
years commencing prior to, or extending beyond, the term of this Lease shall be
prorated to coincide with the corresponding Commencement Date or Expiration
Date.

      10.3  Additional Improvements. Operating Expenses shall not include Real
Property Taxes attributable to improvements placed upon the Industrial Center by
other tenants or by Landlord for the exclusive enjoyment of such other tenants.
Notwithstanding Paragraph 10.1 hereof, Tenant shall, however, pay to Landlord at
the time Operating Expenses are payable under Paragraph 4.2, the entirety of any
increase in Real Property Taxes if assessed by reason of improvements placed
upon the Premises by Tenant or at Tenant's request.

      10.4  Joint Assessment. If the Building is not separately assessed, Real
Property Taxes allocated to the Building shall be an equitable proportion of the
Real Property Taxes for all of the land and improvements included within the tax
parcel assessed.

      10.5  Tenant's Property Taxes. Tenant shall pay prior to delinquency all
taxes assessed against and levied upon Tenant's improvements, fixtures,
furnishings, equipment and all personal property of Tenant contained in the
Premises or stored within the Industrial Center.

11.   UTILITIES. Tenant shall pay directly for all utilities and services
supplied to the Premises, including but not limited to electricity, telephone,
security, gas and cleaning of the Premises, together with any taxes thereon.

12.   ASSIGNMENT AND SUBLETTING.

      12.1  Landlord's Consent Required.

            (a)   Tenant shall not assign, transfer, mortgage or otherwise
transfer or encumber (collectively, "assign") or sublet all or any part of
Tenant's interest in this Lease or in the Premises without Landlord's prior
written consent which consent shall not be unreasonably withheld. Relevant
criteria in determining reasonability of consent include, but are not limited
to, credit history of a proposed assignee or sublessee, references from prior
landlords, any change or intensification of use of the Premises or the Common
Areas and any limitations imposed by the Internal Revenue Code and the
Regulations promulgated thereunder relating to Real Estate Investment Trusts.
Assignment or sublet shall not release Tenant from its obligations hereunder.
Tenant shall not (i) sublet or assign or enter into other arrangements such that
the amounts to be paid by the sublessee or assignee thereunder would be based,
in whole or in part, on the income or profits derived by the business activities
of the sublessee or assignee; (ii) sublet the Premises or assign this Lease to
any person in which Landlord owns an interest, directly or indirectly (by
applying constructive ownership rules set forth in Section 856(d)(5) of the
Internal Revenue Code (the "Code"); or (iii) sublet the Premises or assign this
Lease in any other manner which could cause any portion of the amounts received
by Landlord pursuant to this Lease or any sublease to fail to qualify as "rents
from real property" within the meaning of Section 856(d) of the Code, or which
could cause any other income received by Landlord to fail to qualify as income
described in Section 856(c)(2) of the Code. The requirements of this Section
12.1 shall apply to any further subleasing by any subtenant.

            (b)   A change in the control of Tenant shall constitute an
assignment requiring Landlord's consent. The transfer, on a cumulative basis, of
25% or more of the voting or management control of Tenant shall constitute a
change in control for this purpose.

            (c)   No acceptance by Landlord of any rent or any other sum of
money from any assignee, sublessee or other category of transferee shall be
deemed to constitute Landlord's consent to any assignment, sublease, or
transfer. No such assignment, subletting, occupancy or collection shall be
deemed the acceptance of the assignee, tenant or occupant, as Tenant, or a
release of Tenant from the further performance by Tenant of Tenant's obligations
under this Lease. Any assignment or sublease consented to by Landlord shall not
relieve Tenant (or its assignee) from obtaining Landlord's consent to any
subsequent assignment or sublease.

      12.2  Rent Adjustment. If, as of the effective date of any permitted
assignment or subletting the then remaining term of this Lease is less than
three (3) years, Landlord may, as a condition to its consent: (i) require that
the amount and adjustment schedule of the rent payable under this Lease be
adjusted to what is then the market value and/or adjustment schedule for
property similar to the Premises as then constituted, as determined by Landlord;
or (ii) terminate the Lease as of the date of assignment or subletting subject
to the performance by Tenant of those covenants which under the terms hereof
survive termination.

13.   DEFAULT; REMEDIES.

      13.1  Default. The occurrence of any one of the following events shall
constitute an event of default on the part of Tenant ("Default"):

            (a)   The abandonment of the Premises by Tenant;

            (b)   Failure to pay any installment of Base Rent, Additional Rent
or any other monies due and payable hereunder, said failure continuing for a
period of 3 days after the same is due;

            (c)   A general assignment by Tenant or any guarantor for the
benefit of creditors;

            (d)   The filing of a voluntary petition in bankruptcy by Tenant or
any guarantor, the filing of a voluntary petition for an arrangement, the filing
of a petition, voluntary or involuntary, for reorganization, or the filing of an
involuntary petition by Tenant's creditors or guarantors;

            (e)   Receivership, attachment, of other judicial seizure of the
Premises or all or substantially all of Tenant's assets on the Premises;

            (f)   Failure of Tenant to maintain insurance as required by
Paragraph 8.2;

            (g)   Any breach by Tenant of its covenants under Paragraph 6.2,
including a material misrepresentation in completion of Tenant's Environmental
and Use Questionnaire (Exhibit C);

            (h)   Failure in the performance of any of Tenant's covenants,
agreements or obligations hereunder (except those failures specified as events
of Default in other Paragraphs of this Paragraph 13.1 which shall be governed by
such other Paragraphs), which failure continues for 10 days after written notice
thereof from Landlord to Tenant provided that, if Tenant has exercised
reasonable diligence to cure such failure and such failure cannot be cured
within such 10 day period despite reasonable diligence, Tenant shall not be in
default under this subparagraph unless Tenant fails thereafter diligently and
continuously to prosecute the cure to completion;

            (i)   Any transfer of a substantial portion of the assets of Tenant,
or any incurrence of a material obligation by Tenant, unless such transfer or
obligation is undertaken or incurred in the ordinary course of Tenants business
or in good faith for equivalent consideration, or with Landlord's consent; and

            (j)   The default of any guarantors of Tenant's obligations
hereunder under any guaranty of this Lease, or the attempted repudiation or
revocation of any such guaranty.

      13.2  Remedies. In the event of any Default by Tenant, Landlord shall have
the remedies set forth in the Addendum attached hereto entitled "Landlord's
Remedies in Event of Tenant Default, State of Florida".

      13.3  Late Charges. Tenant hereby acknowledges that late payment by Tenant
to Landlord of rent and other sums due hereunder will cause Landlord 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. Accordingly, if any installment of rent or
other sum due from Tenant shall not be received by Landlord or Landlord's
designee within 10 days after such amount shall be due, then, without any
requirement for notice to Tenant, Tenant shall pay to Landlord a late charge
equal to 5% of such overdue amount. The parties hereby agree that such late
charge represents a fair and reasonable estimate of the costs Landlord will
incur by reason of late payment by Tenant. Acceptance of such late charge by
Landlord shall in no event constitute a waiver of Tenant's Default with respect
to such overdue amount, nor prevent Landlord from exercising any of the other
rights and remedies granted hereunder.

14.   CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of exercise of said power (all
of which are herein called "condemnation"), this Lease shall terminate as to the
part so taken as of the date the condemning authority takes title or possession,
whichever first occurs. If more than 10% of the floor area of the Premises, or
more than 25% of the portion of the Common Areas designated for Tenant's
parking, is taken by condemnation, Tenant may, at Tenant's option, to be
exercised in writing within 10 days after Landlord shall have given Tenant
written notice of such taking (or in the absence of such notice, within 10 days
after the condemning authority shall have taken possession) terminate this Lease
as of the date the condemning authority takes such possession. If Tenant does
not terminate this Lease in accordance with the foregoing, this Lease shall
remain in full force and effect as to the portion of the Premises remaining,
except that the Base Rent shall be reduced in the same proportion as the
rentable floor area of the Premises taken bears to the total rentable floor area
of the Premises. No reduction of Base Rent shall occur if the condemnation does
not apply to any portion of the Premises. Any award for the taking of all or any
part of the Premises under the power of eminent domain or any payment made under
threat of the exercise of such power shall be the property of Landlord,
provided, however, that Tenant shall be entitled to any compensation, separately
awarded to Tenant for Tenant's relocation expenses and/or loss of Tenants trade
fixtures. In the event that this Lease is not terminated by reason of such
condemnation, Landlord shall to the extent of its net severance damages in the
condemnation matter, repair any damage to the Premises caused by such
condemnation authority. Tenant shall be responsible for the payment of any
amount in excess of such net severance damages required to complete such repair.

15.   ESTOPPEL CERTIFICATE AND FINANCIAL STATEMENTS.

      15.1  Estoppel Certificate. Each party (herein referred to as "Responding
Party") shall within 10 days after written notice from the other Party (the
"Requesting Party") execute, acknowledge and deliver to the

brightstar lease

                                       9

<PAGE>

Requesting Party, to the extent it can truthfully do so, an estoppel certificate
in the form attached hereto, plus such additional information, confirmation a/or
statements as be reasonably requested by the Requesting Party.

      15.2  Financial Statement. If Landlord desires to finance, refinance, or
sell the Building, Industrial Center or any part thereof, Tenant and all
Guarantors shall deliver to any potential lender or purchaser designated by
Landlord such financial statements of Tenant and such Guarantors as may be
reasonably required by such lender or purchaser, including but not limited to
Tenant's financial statements for the past 3 years. All such financial
statements shall be received by Landlord and such lender or purchaser in
confidence and shall be used only for the purposes herein set forth.

16.   ADDITIONAL COVENANTS AND PROVISIONS.

      16.1  Severability. The invalidity of any provision of this Lease, as
determined by a court of competent jurisdiction, shall not affect the validity
of any other provision hereof.

      16.2  Interest on Past-Due Obligations. Any monetary payment due Landlord
hereunder not received by Landlord within 10 days following the date on which it
was due shall bear interest from the date due at 12% per annum, but not
exceeding the maximum rate allowed by law in addition to the late charge
provided for in Paragraph 13.3.

      16.3  Time of Essence. Time is of the essence with respect to the
performance of all obligations to be performed or observed by the Parties under
this Lease.

      16.4  Landlord Liability. Tenant, its successors and assigns, shall not
assert nor seek to enforce any claim for breach of this Lease against any of
Landlord's assets other than Landlord's interest in the Industrial Center.
Tenant agrees to look solely to such interest for the satisfaction of any
liability or claim against Landlord under this Lease. In no event whatsoever
shall Landlord (which term shall include, without limitation, any general or
limited partner, trustees, beneficiaries, officers, directors, or stockholders
of Landlord) ever be personally liable for any such liability.

      16.5  No Prior or Other Agreements. This Lease contains all agreements
between the Parties with respect to any matter mentioned herein, and supersedes
all oral, written prior or contemporaneous agreements or understandings.

      16.6  Notice Requirements. All notices required or permitted by this Lease
shall be in writing and may be delivered in person (by hand or by messenger or
courier service) or may be sent by regular, certified or registered mail or U.S.
Postal Service Express Mail, with postage prepaid, or by facsimile transmission
during normal business hours with confirmation of receipt, and shall be deemed
sufficiently given if served in a manner specified in the Paragraph 16.6. The
addresses and facsimile numbers noted adjacent to a Party's signature on this
Lease shall be that Party's address for delivery, mailing or facsimile
transmission of notices. Either Party may by written notice to the other specify
a different address for notice purposes, except that upon Tenant's taking
possessing of the Premises, the Premises shall constitute Tenant's address for
the purpose of mailing or delivering notices to Tenant. A copy of all notices
required or permitted to be given to Landlord hereunder shall be concurrently
transmitted to such party or parties at such addresses as noted below Landlord's
signature block or as Landlord may from time to time hereafter designate by
written notice to Tenant.

      16.7  Date of Notice. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon. If sent
by regular mail, the notice shall be deemed given 48 hours after the same is
addressed as required herein and mailed with postage prepaid. Notices delivered
by United States Express Mail or overnight courier that guarantees next day
delivery shall be deemed given 24 hours after delivery of the same to the United
States Postal Service or courier. If any notice is transmitted by facsimile
transmission or similar means, the same shall be deemed served or delivered upon
telephone or facsimile confirmation of receipt of the transmission thereof,
provided a copy is also delivered via hand or overnight delivery or certified
mail. If notice is received on a Saturday or a Sunday or a legal holiday, it
shall be deemed received on the next business day.

      16.8  Waivers. No waiver by Landlord of a Default by Tenant shall be
deemed a waiver of any other term, covenant or condition hereof, or of any
subsequent Default by Tenant of the same or any other term, covenant or
condition hereof.

      16.9  Holdover. Tenant has no right to retain possession of the Premises
or any part thereof beyond the expiration or earlier termination of this Lease.
If Tenant holds over with the consent of Landlord: (i) the Base Rent payable
shall be increased to 175% of the Base Rent applicable during the month
immediately preceding such expiration or earlier termination; (ii) Tenant's
right to possession shall terminate on 30 days notice from Landlord and (iii)
all other terms and conditions of this Lease shall continue to apply. Nothing
contained herein shall be construed as a consent by Landlord to any holding over
by Tenant. Tenant shall indemnify, defend and hold Landlord harmless from and
against any and all claims, demands, actions, losses, damages, obligations,
costs and expenses, including, without limitation, attorneys' fees incurred or
suffered by Landlord by reason of Tenant's failure to surrender the Premises on
the expiration or earlier termination of this Lease in accordance with the
provisions of this Lease.

      16.10 Cumulative Remedies. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies in
law or in equity.

      16.11 Binding Effect: Choice of Law. This Lease shall be binding upon the
Parties, their personal representatives, successors and assigns and be governed
by the laws of the State in which the Premises are located. Any litigation
between the Parties hereto concerning this Lease shall be initiated in the
county in which the Premises are located.

      16.12 Landlord. The covenants and obligations contained in this Lease on
the part of Landlord are binding on Landlord, its successors and assigns, only
during and in respect of their respective period of ownership of such interest
in the Industrial Center. In the event of any transfer or transfers of such
title to the Industrial Center, Landlord (and in case of any subsequent
transfers or conveyances, the then grantor) shall be concurrently freed and
relieved from and after the date of such transfer or conveyance, without any
further instrument or agreement, of all liability with respect to the
performance of any covenants or obligations on the part of Landlord contained in
this Lease thereafter to be performed.

      16.13 Attorneys' Fees and Other Costs. If any Party brings an action or
proceeding to enforce the terms hereof or declare rights hereunder, the
Prevailing Party (as hereafter defined) in any such proceeding shall be entitled
to reasonable attorneys' fees. The term "Prevailing Party" shall include,
without limitation, a Party who substantially obtains or defeats the relief
sought. Landlord shall be entitled to attorneys' fees, costs and expenses
incurred in preparation and service of notices of Default and consultations in
connection therewith, whether or not a legal action is subsequently commenced in
connection with such Default or resulting breach. Tenant shall reimburse
Landlord on demand for all reasonable legal, engineering and other professional
services expenses incurred by Landlord in connection with all requests by Tenant
for consent or approval hereunder.

      16.14 Landlord's Access; Showing Premises; Repairs. Landlord and
Landlord's agents shall have the right to enter the Premises at any time, in the
case of an emergency, and otherwise at reasonable times upon reasonable notice
for the purpose of showing the same to prospective purchasers, lenders, or
tenants, and making such alterations, repairs, improvements or additions to the
Premises or to the Building, as Landlord may reasonably deem necessary. Landlord
may at any time place on or about the Premises or Building any ordinary "For
Sale" signs and Landlord may at any time during the last 180 days of the term
hereof place on or about the Premises any ordinary "For Lease" signs. All such
activities of Landlord shall be without abatement of rent or liability to
Tenant.

      16.15 Signs. Tenant shall not place any signs at or upon the exterior of
the Premises or the Building, except that Tenant may, with Landlord's prior
written consent, install (but not on the roof) such signs as are reasonably
required to advertise Tenant's own business so long as such signs are in a
location designated by Landlord and comply with sign ordinances and the signage
criteria established for the Industrial Center by Landlord.

      16.16 Termination: Merger. Unless specifically stated otherwise in writing
by Landlord, the voluntary or other surrender of this Lease by Tenant, the
mutual termination or cancellation hereof, or a termination hereof by Landlord
for Default by Tenant, shall automatically terminate any sublease or lesser
estate in the Premises; provided, however, Landlord shall, in the event of any
such surrender, termination or cancellation, have the option to continue any one
or all of any existing subtenancies. Landlord's failure within 10 days following
any such event to make a written election to the contrary by written notice to
the holder of any such lesser interest, shall constitute Landlord's election to
have such event constitute the termination of such interest.

      16.17 Quiet Possession. Upon payment by Tenant of the Base Rent and
Additional Rent for the Premises and the performance of all of the covenants,
conditions and provisions on Tenant's part to be observed and performed under
this Lease, Tenant shall have quiet possession of the Premises for the entire
term hereof subject to all of the provisions of this Lease.

      16.18 Subordination; Attornment; Non-Disturbance.

            (a)   Subordination. This Lease shall be subject and subordinate to
any ground lease, mortgage, deed of trust, or other hypothecation or mortgage
(collectively, "Mortgage") now or hereafter placed by Landlord upon the real
property of which the Premises are a part, to any and all advances made on the
security thereof and to all renewals, modifications, consolidations,
replacements and extensions thereof. Tenant agrees that any person holding any
Mortgage shall have no duty, liability or obligation to perform any of the
obligations of Landlord under this Lease. In the event of Landlord's default
with respect to any such obligation, Tenant will give any Lender, whose name and
address have previously in writing been furnished Tenant, notice of a default by
Landlord. Tenant may not exercise any remedies for default by Landlord unless
and until Landlord and the Lender shall have received written notice of such
default and a reasonable time (not less than 90 days) shall thereafter have
elapsed without the default having been cured. If any Lender shall elect to have
this Lease superior to the lien of its Mortgage and shall give written notice
thereof to Tenant, this Lease shall be deemed prior to such Mortgage. The
provisions of a Mortgage relating to the disposition of condemnation and
insurance proceeds shall prevail over any contrary provisions contained in this
Lease.

            (b)   Attornment. Subject to the non-disturbance provisions of
subparagraph C of this Paragraph 16.18, Tenant agrees to attorn to a Lender or
any other party who acquires ownership of the Premises by reason of a
foreclosure of a Mortgage. In the event of such foreclosure, such new owner
shall not: (i) be liable for any act or omission of any prior landlord or with
respect to events occurring prior to acquisition of ownership, (ii) be subject
to any offsets or defenses which Tenant might have against any prior Landlord,
or (iii) be liable for security deposits or be bound by prepayment of more than
one month's rent.

            (c)   Non-Disturbance. With respect to Mortgage entered into by
Landlord after the execution of this Lease, Tenant's subordination of this Lease
shall be subject to receiving assurance (a "non-disturbance agreement") from the
Mortgage holder that Tenant's possession and this Lease will not be disturbed so
long as Tenant is not in default and attorns to the record owner of the
Premises.

<PAGE>

            (d)   Self-Executing. The agreements contained in this Paragraph
16.18 shall be effective without the execution of any further documents;
provided, however, that upon written request from Landlord or a Lender in
connection with a sale, financing or refinancing of Premises, Tenant and
Landlord shall execute such further writings as may be reasonably required to
separately document any such subordination or non-subordination, attornment
and/or non-disturbance agreement as is provided for herein. Landlord is hereby
irrevocably vested with full power to subordinate this Lease to a Mortgage.

      16.19 Rules and Regulations. Tenant agrees that it will abide by, and to
cause its employees, suppliers, shippers, customers, tenants, contractors and
invitees to abide by all reasonable rules and regulations ("Rules and
Regulations," attached as Exhibit B) which Landlord may make from time to time
for the management, safety, care, and cleanliness of the Common Areas, the
parking and unloading of vehicles and the preservation of good order, as well as
for the convenience of other occupants or tenants of the Building and the
Industrial Center and their invitees. Landlord shall not be responsible to
Tenant for the non-compliance with said Rules and Regulations by other tenants
of the Industrial Center.

      16.20 Security Measures. Tenant acknowledges that the rental payable to
Landlord hereunder does not include the cost of guard service or other security
measures. Landlord has no obligations to provide same. Tenant assumes all
responsibility for the protection of the Premises, Tenant, its agents and
invitees and their property from the acts of third parties.

      16.21 Reservations. Landlord reserves the right to grant such easements
that Landlord deems necessary and to cause the recordation of parcel maps, so
long as such easements and maps do not reasonably interfere with the use of the
Premises by Tenant. Tenant agrees to sign any documents reasonable requested by
Landlord to effectuate any such easements or maps.

      16.22 Conflict. Any conflict between the printed provisions of this Lease
and the typewritten or handwritten provisions, including a Special Terms
Addendum, if any, shall be controlled by the typewritten or handwritten
provisions.

      16.23 Offer. Preparation of this Lease by either Landlord or Tenant or
Landlord's agent or Tenant's agent and submission of same to Tenant or Landlord
shall not be deemed an offer to lease. This Lease is not intended to be binding
until executed and delivered by all Parties hereto.

      16.24 Amendments. This Lease may be modified only in writing, signed by
the parties in interest at the time of the modification.

      16.25 Multiple Parties. Except as otherwise expressly provided herein, if
more than one person or entity is named herein as Tenant, the obligations of
such persons shall be the joint and several responsibility of all persons or
entities named herein as such Tenant.

      16.26 Authority. Each person signing on behalf of Landlord or Tenant
warrants and represents that she or is authorized to execute and deliver this
Lease and to make it a binding obligation of Landlord or Tenant.

      16.27 Brokers. Tenant represents and warrants to Landlord that, except for
those parties set forth in Paragraph 1.12 (the "Brokers"), Tenant has not
engaged or had any conversations or negotiations with any broker, finder or
other third party concerning the leasing of the Premises to Tenant who would be
entitled to any commission or fee based on the execution of this Lease. Tenant
hereby further represents and warrants to Landlord that Tenant is not receiving
and is not entitled to receive any rebate, payment or other remuneration, either
directly or indirectly, from the Brokers, and that it is not otherwise sharing
in or entitled to share in any commission or fee paid to the Brokers by Landlord
or any other party in connection with the execution of this Lease, either
directly or indirectly. Tenant hereby indemnifies Landlord against and from any
claims for any brokerage commissions (except those payable to the Brokers, all
of which are payable by Landlord pursuant to a separate agreement) and all
costs, expenses and liabilities in connection therewith, including, without
limitation, reasonable attorneys' fees and expenses, for any breach of the
foregoing. The foregoing indemnification shall survive the termination of this
Lease for any reason.

      16.28 Usufruct. This contract shall create the relationship of landlord
and tenant between Landlord and Tenant; no estate shall pass out of Landlord;
Tenant has a usufruct, not subject to levy and sale, and not assignable by
Tenant except as expressly set forth herein.

      16.29 Lease Captions. The captions of this Lease are for convenience only
and are not a part of this Lease, and do not in any way define, limit, describe
or amplify the terms or provisions of this Lease or the scope or intent thereof.

      16.30 Counterparts. This Lease may be executed in multiple counterparts,
each of which shall constitute an original, but all of which taken together
shall constitute one and the same agreement.

      16.31 Interpretation. The parties acknowledge that this Lease is the
result of negotiations between the parties, and in construing any ambiguity
hereunder no presumption shall be made in favor of either party. No inference
shall be made from any item, which has been stricken from this Lease other than
the deletion of such item.

      16.32 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

                                    ADDENDUM

               LANDLORD'S REMEDIES IN THE EVENT OF TENANT DEFAULT
                               (STATE OF FLORIDA)

      In the event of any Default by Tenant, in addition to all remedies
available at law or in equity, Landlord may at any time thereafter, with or
without notice, and without limiting Landlord in the exercise of any right or
remedy which Landlord may have by reason of such Default:

            (a)   Terminate Tenant's right to possession of the Premises by any
      lawful means, in which case the term of this Lease shall expire and Tenant
      shall immediately surrender possession of the Premises to Landlord. In
      such event, 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, reasonable attorneys' fees, and any real estate commission
      actually paid or required to be paid.

            (b)   Reenter and take possession of the Premises and relet the same
      for Tenant's account, holding Tenant liable in damages for all expenses
      incurred by Landlord in any such reletting and for any difference between
      the amount of rents received from such reletting and those due and payable
      under the terms of this Lease, and Landlord shall not be deemed to have
      thereby accepted a surrender of the Premises. In the event Landlord relets
      the Premises, Landlord shall have the right to lease or let the Premises
      or portions thereof for such periods of time and at such rents and for
      such use and upon such covenants and conditions as Landlord, in its sole
      discretion, may elect, and Landlord may make such repairs and improvements
      to the Premises as may be necessary. Landlord shall be entitled to bring
      such actions or proceedings for the recovery of any deficits due to
      Landlord as it may deem advisable, without being obligated to wait until
      the end of the term, and commencement or maintenance of any one or more
      actions shall not bar Landlord from bringing other or subsequent actions
      for further accruals, nor shall anything in this subparagraph (b) limit or
      prohibit Landlord's right at any time to accelerate all rents and charges
      due from Tenant to the end of the term, or to terminate this Lease by
      giving notice to Tenant.

            (c)   Declare all rents and charges due hereunder immediately due
      and payable, and thereupon all such rents and fixed charges to the end of
      the term shall thereupon be accelerated; provided, however, such
      accelerated amounts shall be discounted to their then present value on the
      basis of a four percent (4%) per annum discount from the respective dates
      that such amount should have been paid hereunder. In the event that any
      charges due hereunder cannot be exactly determined as of the date of
      acceleration, the amount of such charges shall be determined by Landlord
      in a reasonable manner based on historical increases in such charges.

            (d)   Pursue any other remedy now or hereafter available to Landlord
      under the laws or judicial decisions of the State of Florida.

      Except for notices expressly required by applicable law, Tenant waives
notice of termination of this Lease, notice of re-entry or institution of legal
proceedings and any right of redemption, re-entry or repossession. 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
Premises or any claim of injury or damage. In the event Landlord commences any
proceeding to enforce this Lease or the landlord/tenant relationship between the
parties, or for nonpayment of minimum rent, additional rent or any other sums
due Landlord from Tenant under this Lease, Tenant will not interpose any
counterclaim of whatever nature or description in any such proceedings unless
the failure to do so would bar Tenant's right to do so in a separate action. In
the event Tenant must, because of applicable court rules, interpose any
counterclaim or other claim against Landlord in such proceedings, Landlord and
Tenant covenant and agree that, in addition to any other lawful remedy of
Landlord, upon motion of Landlord, such counterclaim or other claim asserted by
Tenant shall be severed out of the proceedings instituted by Landlord (and, if
necessary, transfer to a court of different jurisdiction), and the proceedings
instituted by Landlord may proceed to final judgment separately and apart from
and without consolidation with or reference to the status of each counterclaim
or any other claim asserted by Tenant. Tenant hereby consents to the
jurisdiction of any state court whose jurisdiction includes the county in which
the Premises are located. In the event of any action or proceeding arising from
this Lease or any other agreement to which Landlord and Tenant are a party,
Tenant hereby stipulates that service of process upon Tenant shall be effective
at the Premises.

      Every term, condition, agreement or provision contained in this Lease
shall be deemed to be also a covenant. The specified remedies to which Landlord
may resort under the terms of this Lease are cumulative and are not intended to
be exclusive of any other remedies or means of redress to which Landlord may be
lawfully entitled in case of any breach or threatened breach by Tenant of any
provision of this Lease. The failure of either party to insist in any one or
more cases upon the strict performance of any of the terms, covenants,
conditions, provisions or agreements of this Lease or to exercise any option
herein contained shall not be construed as a waiver or a relinquishment for the
future of any such term, covenant, condition, provision, agreement or option. A
receipt and acceptance by Landlord of rent or any other payment, or the
acceptance of performance of anything required by this Lease to be performed,
with knowledge of the breach of any term, covenant, condition, provision or
agreement of this Lease, shall not be deemed a waiver of such breach, nor shall
any such acceptance of rent in a lesser amount than is herein provided for
(regardless of any endorsement on any check, or any statement in any letter
accompanying any payment of rent) operate or be construed either as an accord
and satisfaction or in any manner other than as a payment on account of the
earliest rent then unpaid by Tenant, and no waiver by Landlord of any term,
covenant, condition, provision or agreement of this Lease shall be deemed to
have been made unless expressed in writing and signed by Landlord. In addition
to the other remedies provided Landlord in this Lease, Landlord shall

brightstar lease

                                       1
<PAGE>

be entitled to the immediate restraint by injunction of any violation or
attempted or threatened violation, of any of the terms, covenants, conditions,
provisions or agreements of this Lease. No act or conduct of Landlord, whether
consisting of the acceptance of the keys to the Premises, or otherwise, shall be
deemed to be or constitute an acceptance of the surrender of the Premises by
Tenant prior to the expiration of the term, and such acceptance by Landlord of
surrender by Tenant shall only flow from and must be evidenced by a written
acknowledgment of acceptance of surrender signed by Landlord.

                   LETTER OF CREDIT/SURETY BOND REQUIREMENTS

      For purposes of the Security Deposit for Tenant's obligations under the
Lease, Tenant may deliver, or cause to be delivered, to Landlord one (1)
unconditional, irrevocable, and transferable Letter of Credit (the "Letter,"
which term shall be deemed to include each replacement thereof), or Surety Bond
(the "Bond," which term shall be deemed to include each replacement thereof),
issued by a bank (the "Issuer") licensed to do business in the State of Florida
(in the case of a Letter), or issued by an insurance company (the "Surety")
licensed to do business in the State of Florida (in the case of a Bond), and in
either case acceptable to Landlord in its reasonable judgment. The Letter or
Bond shall be in the amount of the security deposit as shown in the Lease and
shall have an expiration date no earlier than one (1) year from its date of
issuance. The Letter or Bond shall automatically renew for a period of no less
than one (1) year from its expiration date, unless Issuer or Surety provides
Landlord with at least sixty (60) days' notice of nonrenewal by certified mail,
return receipt requested. The Letter or Bond shall be in a form acceptable to
Landlord and shall provide that it may be drawn against, in whole or in part, by
presentation to the Issuer or Surety of a sight draft in the appropriate amount
identifying the Letter or Bond being drawn, along with a letter from Landlord to
the Issuer or Surety stating that Tenant is in default of the Lease. No other
requirements shall be imposed as a condition of drawing on the Letter or Bond.
The Letter or Bond shall state that if the Letter or Bond is presented for
payment prior to 10:00 a.m. on a business day, payment will be made by the close
of business on the following business day. The Letter or Bond shall be
accompanied by a letter from an officer of the Issuer or Surety naming the
officer(s) empowered to bind the Issuer or Surety on such Letter or Bond. The
Letter or Bond shall be manually signed by the corporate secretary (or another
officer) of the Issuer or Surety who shall also certify that as of the date of
issue of the Letter or Bond of the officer(s) executing same was fully empowered
to execute such Letter or Bond and to bind the Issuer or Surety thereby.

      If at any time Landlord receives notice of nonrenewal of the Letter or
Bond as described above, then within thirty (30) days after Landlord receives
such notice, Tenant shall deliver to Landlord a replacement Letter or Bond for
the Letter or Bond, which replacement Letter or Bond shall (a) be unconditional,
irrevocable, and transferable, (b) be issued by Issuer or Surety or another bank
or insurance company licensed to do business in the State of Florida, and
acceptable to Landlord in its reasonable judgment, (c) be in an amount not less
than the undrawn balance of the Letter or Bond being replaced, or as may be
approved by Landlord in writing, (d) have an expiration date no earlier than
twelve (12) months from its issuance, and (e)be in form acceptable to Landlord
and shall be available by sight draft with no additional documents or
requirements, other than those stated above. If Tenant fails to properly deliver
to Landlord any required replacement Letter or Bond, Landlord may draw upon the
unreplaced Letter or Bond for all or any part of the amount thereof.

      Without notice to Tenant, Landlord shall be entitled to draw the full
amount, or any remaining portion thereof, of the Letter or Bond if (a) a default
under the Lease has occurred and is continuing and Landlord is entitled to
exercise its rights and remedies under the Lease, or (b) Landlord is not
furnished any replacement Letter or Bond when and in accordance with the terms
hereof. If the Letter or Bond is drawn in full, the amounts received by Landlord
pursuant thereto may be applied to the amounts due under the Lease in such order
or manner as Landlord may, in its sole discretion, elect.

      Notwithstanding the foregoing, Landlord shall not be required to release
all or any remaining portion of the Letter or Bond if there exists any uncured
default under the Lease after applicable notice and cure periods, or an event or
circumstance has occurred which, with the giving of notice or the passing of
time, or both, would constitute a default under the Lease. In addition, if at
any time during the term of the Lease the rating of the Issuer or Surety by
Standard & Poor, Moody's, or a similar nationally recognized rating organization
is ever lower than the rating of the Issuer or Surety as of the date of the
Lease, then, at Landlord's option, Tenant shall replace the Letter or Bond with
a Letter or Bond issued by a different bank or insurance company reasonably
acceptable to Landlord, or, if Tenant is unable to replace the Letter or Bond,
Tenant shall post a cash security deposit with Landlord in the amount of the
Letter or Bond.
