                              W I T N E S S E T H:

         THAT LANDLORD, in consideration of the rents and agreements hereafter
promised and agreed by Tenant to be paid and performed, does hereby lease to
Tenant, and Tenant does hereby lease from Landlord, the Premises described
herein, subject to the following terms.

                                    ARTICLE I

                          DESCRIPTION OF PROPERTY; TERM

         SECTION 1.1 DESCRIPTION OF PROPERTY. Landlord hereby leases to Tenant
and Tenant hereby leases from Landlord approximately 3,406 rentable square feet
of office space on the second (2nd) floor (hereinafter referred to as the
"Premises") approximately as shown on Exhibit "A" attached hereto and made a
part of this Lease, (which rentable square footage and any other amounts set
forth in this Lease which are a function of rentable square footage, shall be
subject to adjustment based upon Landlord's final "as-built" measurement of the
Premises) in the building now known as "Sawgrass Plaza" and located at Sawgrass
Corporate Parkway, Sunrise, Florida 33323, (hereinafter referred to as the
"Building"), as described in Exhibit "B" (Legal Description) and depicted on the
site plan attached hereto as Exhibit "C", together with the right to use in
common with other tenants of the Building, their invitees, customers and
employees, the lobby areas, stairways, elevators, hallways, lavatories and all
other common facilities contained in the Building and parking areas. All of the
land and real property underlying the Building or adjacent thereto, with all
improvements thereto including the Building, and used in connection with the
operation of the Building shall be referred to herein as the "Property".
Landlord represents that prior to the commencement of the Lease Term (defined
below) Landlord shall construct the Building consistent with plans and
specifications for the Building with infrastructure work complete so as to
provide Tenant with sufficient access to the Building. Landlord further
represents that the Building shell and interior common areas shall be completed
in a good and workmanlike manner and in compliance with all federal, state and
local law.

         SECTION 1.1(a) RIGHT OF OFFER. Provided Tenant has not been in default
of any terms or conditions of this Lease and provided Tenant has notified
Landlord, in writing, of an additional space requirement, Landlord shall notify
Tenant of the upcoming availability of any space in the Building and Tenant
shall have the right of first offer to lease such space upon terms and
conditions mutually agreed upon by Landlord and Tenant, subject and subordinate
to any other rights to such space existing as of the date hereof. Tenant shall
have five (5) days following receipt of Landlord's notification of the upcoming
availability of space in the Building within which to exercise the right of
first offer. If Tenant declines the right of first offer, or fails to respond to
Landlord's notification within the five (5) day period, Landlord shall
thereafter be free to market the space to third party tenants.

         SECTION 1.2 TERM. Tenant shall have and hold the Premises for a term of
approximately four (4) years and five (5) months (hereinafter referred to as the
"Term" or "Lease Term"), commencing upon receipt of a certificate of occupancy
for the Premises which is anticipated to be on or about July 1, 1999 in
accordance with the Critical Path attached hereto as Exhibit "G" (the
"Commencement Date") and expiring on November 24, 2003 (the "Expiration Date").
In the event the Commencement Date occurs on a day other than the first day of a
calendar month, the first Base Rent and Additional Rent (hereinafter defined)
payment shall be in the amount of the Base Rent and Additional Rent for the next
full calendar month plus the prorated Base Rent and Additional Rent for the
calendar month in which the Term of this Lease commences, such payment to be due
on the Commencement Date. The parties hereto agree that when the dates of
commencement and termination of this Lease are determined, they will execute an
Estoppel Certificate in the form attached hereto as


                                       1

<PAGE>   3


Exhibit "D", certifying said dates. Tenant's intentional failure or refusal to
execute said Estoppel Certificate shall constitute a default hereunder.

                                   ARTICLE II

                                    BASE RENT

         SECTION 2.1 BASE RENT; LATE CHARGE; SALES TAX. Commencing on the
Commencement Date, Tenant agrees to pay Landlord base rent for the first year of
the Lease Term in the amount of $14.50 times the rentable square footage of the
Premises as set forth in Section 1.1 above (the "Base Rent"), payable in twelve
(12) equal monthly installments due on or before the first day of each and every
month during the first year of the Lease Term. In addition, Tenant shall be
responsible for the payment of Additional Rent (hereafter defined) as provided
in Article III below (the Base Rent and Additional Rent shall be considered Rent
as that term is used in Florida Statute Chapter 83 and shall sometimes be
collectively referred to as the "Rent"). In the event any monthly Rent payment
is not paid within five (5) business days after it is due, Tenant agrees to pay
a late charge of ten (10%) percent of the amount of the payment due. Tenant
further agrees that the late charge imposed is fair and reasonable, complies
with all laws, regulations and statutes, and constitutes an agreement between
Landlord and Tenant as to the estimated compensation for costs and
administrative expenses incurred by Landlord due to the late payment of Rent by
Tenant. Tenant further agrees that the late charge assessed pursuant to this
Lease is not interest, and the late charge assessed does not constitute a lender
or borrower/creditor relationship between Landlord and Tenant, and may be
treated by Landlord as Additional Rent owed by Tenant. Tenant shall pay to
Landlord all sales, use or other taxes pertaining to the Rent which shall be
remitted by Landlord to the Florida Department of Revenue or other appropriate
taxing authority.

         SECTION 2.2 BASE RENTAL ADJUSTMENT. Commencing on the first anniversary
of the Lease (provided such anniversary date falls on the first day of the
month, otherwise on the first day of the following month) and each and every
anniversary thereafter, the Base Rent shall increase by three (3%) percent over
the previous year's Base Rent.

         SECTION 2.3 PAYMENT WITHOUT NOTICE OR DEMAND. The Rent called for in
this Lease shall be paid to Landlord without notice or demand, and without
counterclaim, offset, deduction, abatement, suspension, deferment, diminution or
reduction. Tenant hereby waives all rights now or hereafter conferred by statute
or otherwise to quit, terminate or surrender this Lease or the Premises or any
part thereof, or to any offset, deduction, abatement, suspensions, deferment,
diminution or reduction of the Rent on account of any such circumstances or
occurrence.

         SECTION 2.4 PLACE OF PAYMENT. All payments of Rent shall be made and
paid by Tenant to Sawgrass Plaza Associates, c/o Stiles Property Management Co.,
6400 N. Andrews Avenue, Fort Lauderdale, Florida 33301, or at such other place
as Landlord may, from time to time, designate in writing to Tenant. All Rent
shall be payable in current legal tender of the United States, as the same is
then by law constituted. Any extension, indulgence, or waiver granted or
permitted by Landlord in the time, manner or mode of payment of Rent, upon any
one (1) or more occasions, shall not be construed as a continuing extension,
indulgence or waiver, and shall not preclude Landlord from demanding strict
compliance herewith.

                                   ARTICLE III

                                 ADDITIONAL RENT

         SECTION 3.1 ADDITIONAL RENT. In addition to the Base Rent, Tenant shall
pay as "Additional Rent" its proportionate share ("Tenant's Proportionate
Share") of the Operating Expenses (as herein defined) of the Building and the
Property and the full cost of items billed on a per square foot basis including
janitorial service. Additional Rent shall be paid to Landlord in accordance with
the following provisions:

         1. Landlord shall furnish to Tenant prior to thirty (30) days after the
beginning of each


                                       2
<PAGE>   4


calendar year, including the first calendar year, a budget setting forth
Landlord's estimate of Operating Expenses for the upcoming year. The Operating
Expenses shall be determined as though the Building were occupied at the actual
occupancy rate or at an occupancy rate of ninety-five (95%) percent, whichever
is higher. Tenant shall pay to Landlord, on the first day of each month as
Additional Rent, an amount equal to one-twelfth (1/12th) of Tenant's
Proportionate Share of Landlord's estimate of the Operating Expenses for that
calendar year. If there shall be any increase or decrease in the Operating
Expenses for any year, whether during or after such year, Landlord shall furnish
to Tenant a revised budget and the Operating Expenses shall be adjusted and paid
or credited, as the case may be. If a calendar year ends after the expiration or
termination of this Lease, the Additional Rent payable hereunder shall be
prorated to correspond to that portion of the calendar year occurring within the
Term of this Lease.

         Notwithstanding the foregoing, in the event the total square footage of
the Building is not ninety-five (95%) percent occupied during any calendar year,
appropriate adjustments shall be made to determine both the estimated and actual
Operating Expenses as though the same had been ninety five (95%) percent
occupied for the full calendar year.

         2. Within 120 days after the end of each calendar year, Landlord shall
furnish to Tenant an operating statement showing the actual Operating Expenses
incurred for the preceding calendar year, which statement shall be signed by an
officer of Landlord and certified as true and correct. Tenant shall either
receive a refund or be assessed an additional sum based upon the difference
between Tenant's Proportionate Share of the actual Operating Expenses and the
Additional Rent payments made by Tenant during said year. Any additional sum
owed by Tenant to Landlord shall be paid within thirty (30) days of receipt of
assessment. Any refund owed by Landlord to Tenant shall be credited toward
Tenant's next month's rental payment. Each operating statement given by Landlord
shall be conclusive and binding upon Tenant unless, within thirty (30) days
after Tenant's receipt thereof, Tenant shall notify Landlord that it disputes
the accuracy of said operating statement. Failure of Landlord to submit the
written statement referred to herein shall not waive any rights of Landlord,
unless such statement is not submitted within nine (9) months from the end of
the prior calendar year.

         3. Landlord's "Operating Expenses", as calculated pursuant to Section
3.1.1 above, shall mean expenses relating to the operation and maintenance of
the Building and the Property, and all amenities and appurtenances relating
thereto, including, without limitation, the following:

         4. "Tenant's Proportionate Share" shall, at any given time, be defined
as that fraction having as a numerator the total rentable square footage leased
hereunder at said time, and having as a denominator the total rentable square

Park. Pursuant to the Declaration, a corporation not-for-profit, known as
Sawgrass Property Owners' Association, Inc. (the "Association") has been formed

to therein. Tenant agrees to pay Tenant's Proportionate Share of any and all
maintenance or other assessments imposed by the Association on Landlord as owner
of the Property, as provided in the Declaration.

         SECTION 3.2 INTERIM OPERATING EXPENSES. During the period from the
Commencement Date through December 31, 1999, Tenant shall pay as Interim
Operating Expenses $7.00 per square foot per year, payable monthly as Additional
Rent, which is merely an estimate of the actual Interim Operating Expenses for
such period. Not later than 120 days after the end of the calendar year,
Landlord shall compute the actual Operating Expenses incurred during such
period. Tenant shall either receive a refund or be assessed an additional sum
based upon the difference between Tenant's Proportionate Share of the actual
Operating Expenses and the payments of Interim Operating Expenses made by Tenant

agrees that "Controllable Operating Expenses" (all expenses other than ad
valorem and non-ad valorem real estate taxes, Building insurance and utilities)
shall not increase by more than six (6%) percent per year over the previous
year's actual Controllable Operating Expenses, cumulative during the Term
hereof, and any renewal terms. Landlord's actual costs for uncontrollable
operating expenses (i.e. real estate taxes, Building insurance and utilities)
shall be passed through to Tenant on a pro-rata basis. Additionally, any
expenses deferred during the first year of operation of the Building because of
construction warranties (i.e. HVAC service contracts, elevator service
contracts, fire/security service contracts, etc.) will be added back to the
operating expenses prior to determining whether or not the controllable
operating expense cap has been exceeded.

of this Lease, Tenant shall pay the sum of $12,300.00 to be held by Landlord as
security for the performance by Tenant of all of the terms, covenants and
conditions hereof and the payment of Rent or any other sum due Landlord
hereunder. It is expressly understood that such deposit shall not be considered
an advance payment of Rent or a measure of Landlord's damages in the event of
default by Tenant. Landlord shall have the right to apply all or any part of the
security deposit against any damage, injury, expense or liability caused
Landlord by Tenant's default after expiration of Tenant's applicable cure
periods, including, but not limited to: (a) unreasonable wear and tear of the
Premises; (b) loss or damage to the Premises or other property of the Landlord
caused by Tenant, Tenant's officers, employees, agents, invitees, or licensees;
(c) the cost of restoring the Premises, except for reasonable wear and tear, to
the same condition it was in at the time Tenant began occupancy thereof; (d)
Rent payments which remain due and owing beyond any applicable grace period.
Landlord shall not be limited in pursuing Landlord's remedies against Tenant for
costs, losses or damages to the Premises or to any other property of Landlord
for any such costs, losses or damages which are in excess of the above described
security deposit. Such money shall bear no interest and may be commingled with
other security deposits or funds of Landlord.

         Additionally, simultaneously with the execution of this Lease, Tenant
shall cause the Corporate Guaranty attached hereto as Exhibit "H" to be executed
by Net Command Tech, Inc. guarantying the full payment and performance of
Tenant's obligations under this Lease.

         SECTION 7.2(A) COMPLETION BY LANDLORD. The Premises shall be deemed
ready for occupancy on the date Landlord's Work is substantially completed and a
Certificate of Occupancy for the Premises is received. The same shall be deemed
substantially completed notwithstanding the fact that minor or insubstantial
details of construction, mechanical adjustment or decoration remain to be
performed, the non-completion of which does not materially interfere with
Tenant's use of the Premises. Landlord shall give Tenant at least ten (10) days
notice of the date on which Landlord


                                       6

                  Tenant or any person, firm or corporation employed by Tenant;

         (e)      Tenant's request for materials, components, finishes or
                  improvements which are not available in a commercially
                  reasonable time given the anticipated date of substantial
                  completion of the Premises by Landlord as set forth herein;

         (f)      Tenant's failure to pay, when due, any amounts required to be
                  paid by Tenant pursuant to this Lease;

         (g)      Tenant's failure to comply with all federal, state, or local
                  laws or regulations, including, without limitation, all codes
                  and ordinances;

         (h)      Tenant's request for additional bidding or rebidding of the
                  cost of all or a portion of the completion of the Premises
                  beyond the dates set forth in the Critical Path;

         (i)      changes or postponements requested by Tenant to the work being
                  completed;

         (j)      any error in plans or other documents caused by Tenant, or its
                  employees or agents; and

         (k)      any other act or omission of Tenant, or its employees or
                  agents which, in Landlord's reasonable opinion, will result in
                  delays beyond the dates set forth in the Critical path;

then the Premises shall be deemed ready for occupancy on the date it would have
been ready, but for such delay, and Rent shall commence as of such earlier date.
Any changes to floor plans after execution of the Lease shall be subject to
Landlord's approval, and furthermore, Tenant shall pay for any extra costs that
may be incurred by Landlord which are caused by the changes so requested by
Tenant.

         SECTION 7.4 ACCEPTANCE OF PREMISES. Tenant acknowledges that Landlord
has not made any representatives or warranties with respect to the condition of
the Premises and neither Landlord nor any assignee of Landlord shall be liable
for any latent defect therein; provided, however, Landlord shall be responsible
for repairing any latent defects. Upon delivery to Tenant, Landlord shall
conduct a walk-through of the Premises with a representative of Tenant at which
time a "punch-list" of items which remain to be completed (the non-completion of
which do not prohibit Tenant's use of the Premises) shall be prepared. Tenant
shall have ten (10) days after possession of the Premises to notify Landlord of
any additional items discovered following the walk-through. Landlord shall
complete (or commence to complete) such "punch-list" items within thirty (30)
days of the Commencement Date of this Lease. The taking of possession of the
Premises by Tenant shall be conclusive evidence that the


                                       7
<PAGE>   9


Premises were in good and satisfactory condition at the time such possession was
taken, except for such "punch list items". If Landlord shall give Tenant
permission to enter into possession of the premises prior to the Commencement
Date, such possession or occupancy shall be deemed to be upon all the terms,
covenants, conditions, and provisions of this Lease, including the execution of
an Estoppel certificate.

                                  ARTICLE VIII

                         LANDLORD AND TENANT OBLIGATIONS

         SECTION 8.1 TENANT'S OBLIGATIONS. Tenant shall be responsible for all
repairs, the need for which arises out of: (a) the performance or existence of
Tenant's Work or alterations; (b) the installation, use or operation of Tenant's
property in the Premises; (c) the moving of Tenant's property in or out of the
Building; (d) the act, omission, misuse or neglect of Tenant or any of its
officers, employees, agents, contractors or invitees. Tenant shall also be
responsible for the replacement of all scratched, damaged or broken doors and
glass in and about the Premises, the maintenance and replacement of window, wall
and floor coverings in the Premises, and for the repair and maintenance of all
sanitary and electrical fixtures therein. All such repairs shall be performed at
such times and in such a manner as shall cause the least interference with the
operation of the Building and the use of the Building by other occupants.

         Section 8.2 LANDLORD'S OBLIGATIONS. Landlord shall maintain the
Building in a first-class operating condition including the common areas of the
Building, the Building's roof structure and landscaped areas, and the plumbing,
ventilation, HVAC and electrical systems serving the Premises. Landlord shall be
obligated to keep and maintain the common areas of the Building, and the systems
and facilities serving the Premises, in good working order and shall make all
repairs as and when needed in or about the common areas, except for those
repairs for which Tenant is responsible pursuant to any of the provisions of
this Lease. Unless resulting from the negligence or willful misconduct of
Landlord, Tenant waives all claims against Landlord for damage to person or
property arising for any reason. Unless resulting from the gross negligence or
willful misconduct of Landlord, Landlord shall not be liable for any damage to
Tenant's property caused by (a) water from bursting or leaking pipes or
waste-water about the Property; (b) from an intentional or negligent act of any
other tenant or occupant of the Building or the Property; (c) fire, hurricane or
other acts of God; or (d) riots or vandals; all such risks shall be assumed by
Tenant. Landlord shall not be required to furnish any services or facilities to,
or to make any repairs to or replacements or alterations of the Premises where
necessitated due to the fault of Tenant, its officers, agents, invitees and
employees. Additionally, Tenant waives any and all claims of any kind, nature
or description against Landlord, arising out of the failure of Landlord from
time to time to furnish any of the services requested to be furnished hereunder
including, without limitation, air conditioning, heat, electricity, elevator
service, and restroom facilities.

         SECTION 8.3 FLOOR LOADS; NOISE AND VIBRATION. Tenant shall not place a
load upon any floor of the Premises which exceeds the load per square foot which
such floor was designed to carry or which is allowed by law. Business machines
and mechanical equipment belonging to Tenant which cause noise, electrical
interference or vibration that may be transmitted to the structure of the
Building or to the Premises to such a degree as to be objectionable to Landlord
shall, at Tenant's expense, be placed and maintained by Tenant in settings of
cork, rubber, or spring-type vibration eliminators sufficient to eliminate such
noise, electrical interference or vibration.

         SECTION 8.4 SERVICES. Landlord shall furnish to the Premises reasonable
quantities of heat, ventilation, air conditioning, electricity, elevator service
and water at all times during the Term of this Lease from 8 a.m. to 7 p.m. on
weekdays, and on Saturdays, from 9 a.m. to 1 p.m. On Sundays and days observed
by the Federal Government or the State of Florida as legal holidays, and such
other days as shall be designated by them as holidays, such service shall not be
provided by Landlord. Landlord will provide after-hour electric service upon
request and Tenant will be charged an hourly rate of $25.00 for each additional
hour, and such rate shall be subject to adjustment consistent with changes in
Florida Power & Light's charge per Kilowatt hour for electrical service that
takes place subsequent to execution of this Lease.


                                       8

         Tenant shall not, without Landlord's prior written consent in each
instance, connect any fixtures, appliances or equipment (other than lamps,
typewriters, personal computers, computer servers, copy and fax machines and
similar small office machines) to the Building's electrical system. Should
Landlord grant such consent, all additional risers or other equipment required
shall be provided by Landlord and the cost thereof shall be paid by Tenant
within 10 days after being billed therefore. As a condition to granting such
consent, Landlord may require Tenant to agree to pay, as an additional
Operating Expense, an amount adequate to compensate for the additional
electrical energy to be made available to Tenant based upon the estimated
additional capacity of such additional risers or other equipment, as determined
by Landlord from time to time.

         SECTION 8.5 JANITORIAL SERVICES.  Landlord shall cause the Premises,
including the exterior and interior of the windows thereof, to be cleaned in a
manner standard to the Building. Tenant shall pay to Landlord on demand, the
additional cost incurred by Landlord for: (a) extra cleaning work in the

normal office areas; (iii) interior glass partitions or unusual quantity of
interior glass surfaces, and (iv) non-building standard materials or finishes

Building of any refuse and rubbish of Tenant in excess of that ordinarily
accumulated in business office occupancy or at times other than Landlord's
standard cleaning times; and (c) the use of the Premises by Tenant other than
during business hours on business days.

         SECTION 8.6 TELEPHONE AND CABLE.  Tenant shall be solely responsible
for all telephone, television, cable and other communication expenses incurred
in connection with Tenant's use of the Premises. Landlord shall provide

                                   ARTICLE IX

                        LANDLORD'S AND TENANT'S PROPERTY

         SECTION 9.1 LANDLORD'S PROPERTY. All fixtures, improvements and
appurtenances attached to or built into the Premises at the commencement of,
or during the Term of this Lease, including permanently affixed carpeting or
other similar personal property, whether or not by or at the expense of
Tenant, shall be and remain a part of the Premises, and shall be deemed the
property of Landlord ("Landlord's Property") and shall not be removed by Tenant
except as set forth herein.

         SECTION 9.2 TENANT'S PROPERTY.  All business and trade fixtures,
machinery and equipment, communications equipment and office equipment, whether
or not attached to or built into the Premises, which are installed in the
Premises by or for the account of Tenant or without expense to Landlord and
which can be removed without damage to any fixture or Tenant Improvement, and
structural damage to the Building, and all furniture, furnishings and other
articles of moveable personal property owned by Tenant and located in the
Premises (hereinafter collectively referred to as "Tenant's Property") shall be
and shall remain the property of Tenant and may be removed by Tenant at any
time during the Term of this Lease so long as Tenant's obligations are current
and no default exists under this Lease. In the event Tenant's Property is so
removed, Tenant shall repair or pay the cost of repairing any damage to the
Premises or to the Building resulting from the installation and/or removal
thereof and restore the Premises to the same physical condition and layout as
they existed at the time Tenant was given possession of the Premises. Any
equipment or other property for which Landlord shall have granted any allowance
or credit to Tenant shall not be deemed to have been installed by or for the
account of Tenant without expense to Landlord, shall not be considered Tenant's
Property and shall be deemed the property of Landlord.

         SECTION 9.3 REMOVAL OF TENANT'S PROPERTY.   At or before the
Expiration Date of this Lease, or within five (5) days after any earlier
termination hereof, Tenant, at its expense, shall remove from the Premises all
of Tenant's Property (except such items thereof as Landlord shall have
expressly permitted to remain, which property shall become the property of
Landlord), and Tenant


                                       9
<PAGE>   11

shall repair any damage to the Premises or the Building resulting from any
installation and/or removal of Tenant's Property, and shall restore the
Premises to the same physical condition and layout as they existed at the time
Tenant was given possession of the Premises (post build-out), reasonable wear
and tear excepted. Any other items of Tenant's Property which shall remain in
the Premises after the Expiration Date of this Lease, or after a period of five
(5) days following an earlier termination date, may, at the option of Landlord,
be deemed to have been abandoned, and in such case, such items may be retained
by, or otherwise disposed of by Landlord. Landlord may request Tenant to remove
and pay to Landlord the cost of repairing any damage to the Premises or the
Building resulting from any installation and/or removal of Tenant's Property
and the cost of restoring the Premises to the same physical condition and
layout as they existed at the time Tenant was given possession of the Premises,
reasonable wear and tear excepted.

         SECTION 9.4  LANDLORD'S LIEN AND SECURITY INTEREST.  As security for
the performance of Tenant's obligations under this Lease, Tenant hereby grants
to Landlord a security interest in, and Landlord's lien upon all of Tenant's
Property located in the Premises. Tenant hereby irrevocably appoints Landlord
as Tenant's attorney-in-fact and empowers Landlord to execute on Tenant's
behalf a UCC-1 Financing Statement, renewals and terminations thereof, for the
purpose of perfecting Landlord's security interest as provided herein or as
otherwise provided by law.

                                   ARTICLE X

                                   INSURANCE

         SECTION 10.1 TENANT'S INSURANCE.

         1.    Tenant shall, during the Term of this Lease, maintain the
following insurance coverages:

               a.    Insurance against public liability, including that from
personal injury or property damage in or about the Premises resulting from the
occupation, use or operation of the Premises, in amount of not less than One
Million ($1,000,000) Dollars Combined Single Limit for both bodily injury and
property damage.

               b.    Insurance upon all property in the Premises owned by
Tenant, or for which Tenant is legally liable. The insurance specified herein
shall provide protection against perils included within the standard Florida
form of fire and extended coverage insurance policy, together with insurance
against vandalism and malicious mischief.

         2.    All policies of insurance required from Tenant in this Section
shall be issued in a form acceptable to Landlord by insurance companies with
general policyholder's rating of "A" as rated in the most current available
"Best's Insurance Reports", and qualified to do business in Florida. Each and
every such policy:

         (a)   shall be issued in the names of Landlord and Tenant and any
         other parties in interest designated in writing by notice from
         Landlord to Tenant ("Additional Party") either as an insured under the
         policy or as additional insured;

         (b)   shall be for the mutual and joint benefit and protection of
         Landlord, Tenant and any Additional Party;

         (c)   shall be delivered to Landlord and any Additional Party by
         delivery of an original certificate of insurance or a certified copy
         on or before delivery of possession of the Premises to Tenant and
         thereafter, within 30 days prior to the expiration of each policy, and
         as often as any such policy shall expire or terminate, renewal or
         additional policies shall be procured and maintained in like manner
         and to like extent;

         (d)   shall contain a provision that the insurer will give to Landlord
         and any Additional Party at least 30 days notice in writing in advance
         of any cancellation, termination or lapse,


                                      10
<PAGE>   12

         or the effective date of any reduction in the amount of insurance;

         (e)   shall be written as a primary policy which does not contribute
         to and is not in excess of coverage which Landlord may carry; and

         (f)   shall contain a provision that Landlord and any Additional
         Party, although named as an insured, shall nevertheless be entitled to
         recover under said policies for any loss occasioned to it, its
         servants, officers, agents, invitees and employees by reason of the
         negligence of Tenant.

         3.    Any insurance provided for in this Section may be maintained by
means of a policy or policies of blanket insurance, provided, however, that:
(i) Landlord and any Additional Party shall be named either as an insured or as
an additional insured thereunder as their respective interest may appear;
(ii) the coverage afforded Landlord and any Additional Party will not be
reduced or diminished by reason of the use of such blanket policy of insurance;
and (iii) the requirements set forth in this Article are otherwise satisfied.

         4.    These insurance requirements are subject to modification in the
event, and to the extent any mortgagee of Landlord requires different
insurance. In such event, the requirements of such mortgagee shall control.

         SECTION 10.2   LANDLORD'S INSURANCE.  Landlord shall carry fire and
extended casualty coverage, to include boiler and machinery coverage, on the
Building with limits equal to the replacement value of the Building. Landlord
shall also carry liability coverage on the Building in the same limits as
required of Tenant. All such insurance policies shall be issued by an insurer
licensed to do business in Florida.

         SECTION 10.3   DESTRUCTION OF THE PREMISES OR BUILDING.  If, during
the Term hereof, the Premises are damaged by reason of fire or other casualty,
Tenant shall give immediate notice thereof to Landlord. Subject to the prior
rights of any mortgagee, Landlord shall restore the Premises to substantially
the same condition they were in immediately before said destruction. If, in
Landlord's reasonable opinion, which opinion shall be rendered within forty
five (45) days of destruction, the restoration can be accomplished within 180
working days following the issuance of a building permit for reconstruction,
such destruction shall not terminate this Lease. If, in Landlord's reasonable
opinion, the restoration cannot be performed within the time stated in this
paragraph, then at any time within the thirty (30) day period after such
determination, either party may terminate this Lease upon fifteen (15) days
notice to the other party during which time Tenant shall remove all of Tenant's
Property from the Premises. If both parties fail to terminate this Lease and
restoration is permitted under existing laws, Landlord shall restore the
Premises within 180 working days following receipt of a building permit for
reconstruction, and this Lease shall continue in full force and effect. Rent
shall be abated during the period in which the Premises (or portion thereof on
a prorated basis) are rendered untenantable as a result of such damage,
unless said damage was caused by the negligence or intentional wrongful act of
Tenant or its officers, employees, agents or invitees. Should this Lease be
terminated by either party, the entire insurance proceeds shall be and remain
the outright property of Landlord, subject to the prior rights of any mortgagee
and except any proceeds received for Tenant's Property, or proceeds received
from Tenant's business interruption insurance, if any.

         In the event that the Building has been damaged or destroyed by fire
or other casualty to the extent that the cost of restoration of the Building
will exceed a sum constituting fifty percent (50%) of the total replacement
cost thereof and Landlord, in its reasonable opinion, determines that the
Premises cannot be restored within the 180 day time period referenced in the
preceding paragraph, which opinion shall be rendered within forty five (45) days
of the date of damage or destruction, then at any time within the thirty (30)
day period after such determination, either Party may terminate this Lease upon
fifteen (15) days notice to the other party, during which time Tenant shall
remove all of Tenant's Property from the Premises. If both parties fail to
terminate the Lease and restoration is permitted under existing laws, Landlord
shall restore the Premises within said 180 day period and this Lease shall
continue in full force and effect. Rent shall be abated during the period in
which the Premises (or portion thereof on a prorated basis) are rendered
untenantable as a result of such damage, unless said


                                      11
<PAGE>   13
damage was caused by the negligence or intentional wrongful act of Tenant or its
officers, employees, agents or invitees. If Landlord fails to restore the
Premises within said 180 days, Tenant may terminate this Lease.


                                   ARTICLE XI

                        ALTERATIONS AND MECHANIC'S LIENS

         SECTION 11.1   ALTERATIONS BY TENANT   No alterations shall be made by
Tenant after completion of Tenant Improvements unless the following conditions
are met:

         (a)   Tenant shall provide a sealed set of plans prepared and
         certified by an architect to Landlord, and Tenant shall have received
         the prior written consent of Landlord;

         (b)   all such alterations or improvements shall be performed by
         Landlord at Tenant's expense, or by a licensed contractor approved by
         Landlord, in Tenant's discretion;

         (c)   Tenant shall have procured all permits, licenses and other
         authorizations required for the lawful and proper undertaking thereof,
         and immediately upon completion of any such alterations, Tenant shall
         obtain a proper Certificate of Occupancy and deliver same to Landlord;

         (d)   all alterations when completed shall be of such a nature as not
         to (i) reduce or otherwise adversely affect the value of the Premises;
         (ii) diminish the general utility or change the general character
         thereof; (iii) result in an increase of the Operating Expenses, or
         (iv) adversely affect the mechanical, electrical, plumbing, security
         or other such systems of the Building or the Premises;

         (e)   all alterations made by Tenant shall remain on and be
         surrendered with the Premises on expiration or termination of this
         Lease, except that Landlord can elect, simultaneously with its
         approval of Tenant's plans and specifications, to require Tenant to
         remove any and all alterations Tenant has made to the Premises.

         (f)   Tenant shall be liable for any increase in the Building
         insurance costs caused, in whole or part, by any alterations make by
         Tenant to the Premises.

         SECTION 11.2  MECHANIC'S, MATERIALMEN'S AND LABORER'S LIENS. Tenant
agrees that it will make full and prompt payment of all sums necessary to pay
for the cost of repairs, alterations, improvements, changes or other work done
by Tenant to the Premises and further agrees to indemnify and hold harmless
Landlord from and against any and all such costs and liabilities incurred by
Tenant, and against any and all mechanic's, materialman's or laborer's liens
arising out of or from such work or the cost thereof which may be asserted,
claimed or charged against the Premises or the Building or Property.
Notwithstanding anything to the contrary in this Lease, the interest of Landlord
in the Premises shall not be subject to liens for improvements made by or for
Tenant, whether or not the same shall be made or done in accordance with any
agreement between Landlord and Tenant, and it is specifically understood and
agreed that in no event shall Landlord or the interest of Landlord in the
Premises be liable for or subjected to any mechanic's, materialmen's or
laborer's liens for improvements or work made by or for Tenant. This Lease
specifically prohibits the subjecting of Landlord's interest in the Premises to
any mechanic's, materialmen's or laborer's liens for improvements made by Tenant
or for which Tenant is responsible for payment under the terms of this Lease.
All persons dealing with Tenant are hereby placed upon notice of this provision.
Tenant shall advise its contractors, subcontractors, materialmen and any other
lienors of this provision. In the event any notice or claim of lien shall be
asserted of record against the interest of Landlord in the Premises or Building
or the site on which it is located on account of or growing out of any
improvement or work done by or for Tenant, or any person claiming by, through or
under Tenant, for improvements or work the cost of which is the responsibility
of Tenant, Tenant agrees to have such notice of claim of lien canceled and
discharged of record as a claim against the interest of Landlord in the Premises
or the


                                      12
<PAGE>   14
Building or Property (either by payment or bond as permitted by law) within ten
(10) days after notice to Tenant by Landlord, and in the event Tenant shall fail
to do so, Tenant shall be considered in default under this Lease.


                                  ARTICLE XII

                           ASSIGNMENT AND SUBLETTING

         SECTION 12.1  TENANT'S TRANSFER.

         (a)   Tenant shall not voluntarily assign or encumber its interest in
this Lease or in the Premises, or sublease all or any part of the Premises, or
allow any other person or entity to occupy or use all or any part of the
Premises, without first obtaining Landlord's written consent, which consent may
be withheld at Landlord's sole discretion. Any assignment, encumbrance or
sublease without Landlord's prior written consent shall be voidable and, at
Landlord's election, shall constitute a default hereunder. No consent to any
assignment, encumbrance, or sublease shall constitute a further waiver of the
provisions of this provision. Notwithstanding the foregoing, Tenant may assign
this Lease or sublet all or a portion of the Premises to an affiliate,
subsidiary or related entity of Tenant without Landlord's prior written consent,
provided Landlord has reasonable approval rights as to any change in the use of
the Premises. An affiliate, subsidiary or related entity of Tenant shall be
defined as one that is 51% owned or controlled by Tenant.

         (b)   If Tenant is a partnership, a withdrawal or change, voluntary,
involuntary, or by operation of law of any partner/or partners owning 50% or
more of the partnership, or the dissolution of the partnership, shall be deemed
a voluntary assignment, subject to the requirements of Paragraph 12.1(a) above.

         (c)   If Tenant is a corporation, Tenant shall provide written notice
to Landlord of any dissolution, merger or consolidation, or other reorganization
of Tenant, or the sale of or the transfer of controlling percentage of the
capital stock of Tenant, or the sale of 51% of the total combined voting power
of all classes of Tenant's capital stock issued, outstanding, and entitled to
vote for the election of directors. Notwithstanding written notice to Landlord,
any such transaction contemplated in this subparagraph (c) shall not be subject
to Landlord's consent.

         (d)   In the event Landlord consents to the sublease of all or any
part of the Premises, such sublease shall be subordinate to and subject to the
terms of this Lease. Landlord shall be entitled to receive the total amount of
any increased Rent provided for in said assignment or sublease, including sales
tax, paid by a sublessee or assignee.

         (e)   Any assignment consented to by Landlord shall be evidenced by a
validly executed assignment and assumption of lease agreement, upon such terms
and provisions as shall be approved by Landlord in its sole discretion.

         (f)   If, without such prior written consent of Landlord, this Lease is
transferred or assigned by Tenant, or if the Premises, or any part thereof, are
sublet or occupied by anybody other than Tenant, whether as a result of any act
or omission by Tenant, or by operation of law or otherwise, Landlord may, in
addition to and not in diminution of, or substitution for, any other rights and
remedies under this Lease, or pursuant to law to which Landlord may be entitled
as a result thereof, collect and retain Rent directly front the transferee,
assignee, subtenant or occupant and apply the net amount collected to the Rent
due from Tenant to Landlord under this Lease.

         SECTION 12.2  TENANT'S LIABILITY.  Notwithstanding any assignment or
sublease, and notwithstanding the acceptance of Rent by Landlord from any such
assignee or sublessee, Tenant shall continue to remain liable for the payment
of Rent hereunder and for the performance of all of the agreements, conditions,
covenants and terms herein contained.

         SECTION 12.3  LANDLORD'S RIGHT OF CANCELLATION.  Notwithstanding
anything contained herein to the contrary, should Tenant desire or attempt to
assign the Lease or sublease the Premises,


                                      13
<PAGE>   15
Landlord shall have the right, but not the obligation, to cancel and terminate
the Lease and deal with Tenant's prospective assignee or sublessee directly and
without any obligation to Tenant.

         SECTION 12.4  LANDLORD'S TRANSFER.  Landlord shall have the right to
sell, assign, mortgage, or otherwise encumber or dispose of Landlord's interest
in the Building, the Property, the Premises and this Lease. In the event of any
such disposition, Landlord shall have no further liability or obligation to
Tenant under this Lease.

         SECTION 12.5  MINIMUM RENTAL REQUIREMENT.   Notwithstanding anything to
the contrary contained in this ARTICLE XII or in this Lease, Tenant may not,
under any circumstances, assign this Lease or sublet the Premises or any part
thereof until at least ninety (90%) percent of the rentable space in the
Building has been leased by Landlord, except in the event of an assignment or
sublease to an affiliate, subsidiary or related entity of Tenant.

                                  ARTICLE XIII

                              OBLIGATION TO COMPLY

         SECTION 13.1  OBLIGATIONS OF TENANT.   Landlord shall, during the Term
of this Lease, comply with all valid laws, ordinances, regulations, orders and
requirements of any governmental authority which may now or hereafter be
applicable to the common areas of the Building or Property. Landlord represents
that, as of the Commencement Date, the Premises, the Building and the Property
are in conformance with all currently existing governmental regulations,
including those imposed by the ADA. Tenant shall, during the Term of this Lease,
at its sole cost and expense, comply with all valid laws, ordinances,
regulations, orders and requirements of any governmental authority which may now
or hereafter be applicable to the Premises or to its use, whether or not the
same shall interfere with the use or occupancy of the Premises, arising from (a)
Tenant's use of the Premises; (b) the manner or conduct of Tenant's business or
operation of its installations, equipment or other property therein; (c) any
cause or condition created by or at the instance of Tenant; or (d) breach of any
of Tenant's obligations hereunder, whether or not such compliance requires work
which is structural or non-structural, ordinary or extraordinary, foreseen or
unforeseen. Tenant shall pay all of the costs, expenses, fines, penalties and
damages which may be imposed upon Landlord by reason or arising out of Tenant's
failure to fully and promptly comply with and observe the provisions of this
Section. Tenant shall give prompt notice to Landlord of any notice it receives
of the violation of any law or requirement of any public authority with respect
to the Premises or the use or occupation thereof. Tenant's obligation to comply
with laws shall include, without limitation, those laws and regulations
contemplated by Sections 24.2 and 24.3 below and Title III of the Americans With
Disabilities Act of 1990, as Amended. In the event Tenant receives any notice
alleging violation of any of the aforementioned laws, ordinances, regulations,
orders, rules or requirements relating to any portion of the Premises, the
Building or of the Property; or any notice of regulatory action or investigation
instituted in connection therewith, Tenant shall provide written notice to
Landlord thereof within ten (10) days after receipt of same by Tenant.

         SECTION 13.2  RULES AND REGULATIONS.   Tenant shall comply with all
rules and regulations now existing (See Exhibit "E"), or as may be subsequently
published by Landlord to tenants of the Building, with ten (10) days written
notice prior to effectiveness or enforcement.

         SECTION 13.3  ATTORNEYS' FEES.   With respect to any default, failure
to perform or any other dispute between Tenant and Landlord arising out of this
Lease, the prevailing party shall be entitled to recover all costs incurred,
including reasonable attorney's fees, which shall include, but not be limited
to, such fees incurred prior to institution of litigation or in litigation,
including trial and appellate review, and in arbitration, bankruptcy or other
administrative or judicial proceeding.

                RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS

         SECTION 14.1  PAYMENT OR PERFORMANCE.  Landlord shall have the right,
upon ten (10) days prior written notice to Tenant (or without notice in case of
emergency or in order to avoid any fine, penalty, or cost which may otherwise
be imposed or incurred), to make any payment or perform any act required of
Tenant under any provision in this Lease, and in exercising such right, to
incur necessary and incidental costs and expenses, including reasonable
attorney's fees. Nothing herein shall imply any obligation on the part of
Landlord to make any payment or perform any act required of Tenant, and the
exercise of the right to do so shall not constitute a release of any
obligation, waiver of any default or obligation of Landlord to make any similar
payment or perform any similar act in the future.

         SECTION 14.2  REIMBURSEMENT.   All payments made, and all costs and
expenses incurred in connection with Landlord's exercise of the right set forth
in Section 14.1, shall be reimbursed by Tenant within ten (10) days after
receipt of a bill setting forth the amounts so expended. Any such payments,
costs and expenses made or incurred by Landlord shall be treated as Rent owed
by Tenant.


                                   ARTICLE XV

                       NON LIABILITY AND INDEMNIFICATION

         SECTION 15.1  NON LIABILITY OF LANDLORD. Neither Landlord, nor any
joint venture partner, officer, director, agent, servant, or employee of
Landlord, nor any Superior Mortgagee (as defined in Article XX below), shall be
liable to Tenant for any loss, injury, or damage to Tenant or to any other
person, or to its property, irrespective of the cause of such injury, damage or
loss, unless caused by or resulting from the negligence of Landlord, in the
operation or maintenance of the Premises or the Building, subject to the
doctrine of comparative negligence in the event of negligence on the part of
Tenant or any of its subtenants, licensees, employees, invitees, officers,
agents or contractors. Tenant agrees that any Superior Mortgagee will not be
liable to Tenant for injury, damage or loss caused by or resulting from the
negligence of Landlord. Further, neither Landlord, nor any Superior Mortgagee,
nor any joint venture partner, director, officer, agent, servant, or employee
of Landlord shall be liable; (a) for any damage caused by other tenants or
persons in, upon or about the Building, or caused by operations in construction
of any private, public or quasi-public work; or (b) for incidental or
consequential damages or lost profits arising out of any loss of use of the
Premises or any equipment or facilities therein by Tenant or any person
claiming through or under Tenant. Tenant shall not hold Landlord liable for any
latent defect in the Premises, the Property or the Building (Landlord shall,
however, be responsible for correcting any latent defects in the Premises or
the Building), nor shall Landlord be liable for injury or damage to person or
property caused by fire, theft, or resulting from the operation of elevators,
heating or air conditioning or lighting apparatus, or from falling plaster, or
from steam, gas, electricity, water, rain, or dampness, which may leak or flow
from any part of the Building or Property, or from the pipes, appliances or
plumbing work of the Building, Premises or Property, however Landlord will carry
insurance coverage for these losses as they relate to the Building, and Tenant
shall carry insurance coverage for these losses as they relate to Tenant's
Property in the Premises.

<PAGE>   17

         SECTION 15.2  INDEMNIFICATION BY TENANT. Tenant shall indemnify and
hold Landlord and all Superior Mortgagees and its or their respective joint
venture partners, directors, officers, agents, employees and invitees, harmless
against and from any and all claims from or in connection with; (a) the conduct
or management of the Premises or any business therein, or any condition created
(other than by Landlord) in or about the Premises during the Term of this Lease
or during the period of time, if any, prior to the Commencement Date that
Tenant may have been given access to the Premises; (b) any act, omission or
negligence of Tenant or any of its subtenants or licensees or its or their
partners, directors, officers, agents, employees or contractors; (c) any
accident, injury or damage whatsoever (unless caused solely by Landlord's gross
negligence) occurring in, at or upon the Premises; and (d) any breach or
default by Tenant in the full and prompt payment and performance of Tenant's
obligations under this Lease; together with all costs, expenses and liabilities
incurred in or in connection with each such claim, action or proceeding brought
against Landlord and/or its employees, including without limitation, all
reasonable attorney's fees and expenses. In case any action or proceeding is
brought against Landlord or a Superior Mortgagee, Tenant, upon notice from
Landlord or such Superior Mortgagee, shall resist and defend such action or
proceeding (by counsel reasonably satisfactory to Landlord or such Superior
Mortgagee).

         SECTION 15.3 INDEMNIFICATION BY LANDLORD. Landlord shall indemnify and
hold Tenant and its joint venture partners, directors, officers, agents,
employees and invitees, harmless against and from any and all claims from or in
connection with: (a) Landlord's conduct within the Premises, or any condition
created by Landlord in or about the Premises during the Term of this Lease;
(b) any act, omission or negligence of Landlord or its partners, directors,
officers, agents, employees or contractors; and (c) any accident, injury or
damage whatsoever (unless caused solely by Tenant, its agents' invitees or
employees' gross negligence) occurring in, at or upon the common areas together
with all costs, expenses and liabilities incurred in or in connection with each
such claim, action or proceeding brought against Tenant and/or its employees,
including without limitation all reasonable attorneys' fees and expenses. In
case any such action or proceeding is brought against Tenant without fault on
its part, Landlord, upon notice from Tenant shall resist and defend such action
or proceeding (by counsel reasonably satisfactory to Tenant).

         SECTION 15.4  INDEPENDENT OBLIGATIONS; FORCE MAJEURE. The obligations
of Tenant hereunder shall not be affected, impaired or excused, nor shall
Landlord have any liability whatsoever to Tenant, because; (a) Landlord is
unable to fulfill, or is delayed in fulfilling, any of its obligations under
this Lease by reason of strike, other labor trouble, governmental action or
inaction, controls or shortages of fuel, supplies, labor or materials, acts of
God or any other cause, whether similar or dissimilar, beyond Landlord's
reasonable control; or (b) of any failure or defect in the supply, quantity or
character of electricity or water furnished to the Premises, by reason of any
requirement, act or omission of the public utility or others serving the
Building with electric energy, steam, oil, gas or water, or for any other
reason whether similar or dissimilar, beyond Landlord's reasonable control.

                                  ARTICLE XVI

                                    DEFAULT

         SECTION 16.1  EVENTS OF DEFAULT.   Tenant shall be in default under
this Lease if any one or more of the following events shall occur:

         (a)   Tenant shall fail to pay any installment of the Rent or any
         other expenses called for hereunder as and when the same shall become
         due and payable, and such default shall continue for a period of five
         (5) days after the same is due; or

         (b)   Tenant shall default in the performance of or compliance with
         any of the other terms or provisions of this Lease, and such default
         shall continue for a period of twenty (20) days after the giving of
         written notice thereof from Landlord to Tenant, or, in the case of any
         such default which cannot, with bona fide due diligence, be cured
         within said twenty (20) days, Tenant shall fail to proceed within said
         twenty (20) day period to cure such default and thereafter to
         prosecute the curing of same with all due diligence (it being intended
         that as to a default not susceptible of being cured with due diligence
         within such period of


                                      16
<PAGE>   18

         twenty (20) days, the time within which such default may be cured
         shall be extended for such period as may be necessary to permit the
         same to be cured with bona fide due diligence); or

         (c)   Tenant shall assign, transfer, mortgage or encumber this Lease
         or sublet the Premises in a manner not permitted by Article XII; or

         (d)   Tenant shall file a voluntary petition in bankruptcy or any
         Order for Relief be entered against it, or shall file any petition or
         answer seeking any arrangement, reorganization, composition,
         re-adjustment or similar relief under any present or future bankruptcy
         or other applicable law, or shall seek or consent to or acquiesce in
         the appointment of any trustee, receiver, or liquidator of Tenant of
         all or any substantial part of Tenant's properties; or

         (e)   If any creditor of Tenant shall file a petition in bankruptcy
         against Tenant or for reorganization of Tenant, under state or federal
         law, and if such petition is not discharged within ninety (90) days
         after the date on which it is filed; or

         (f)   Tenant shall vacate or abandon the Premises,

then, and in any such event, or during the continuation thereof (subject to the
time period described in subparagraph (e) above, Landlord may, at its option
elect any remedy available under Florida Law or as provided in Article XVII.

         SECTION 16.2  HOLDOVER.    Should Tenant hold over and remain in
possession of the Premises at the expiration of any Term hereby created, Tenant
shall, by virtue of this Section, become a tenant-at-sufferance and shall pay
Landlord twice the Rent per month of the last monthly installment of Rent above
provided to be paid. Said tenancy shall be subject to all the conditions and
covenants of this Lease as though the same had been a tenancy-at-sufferance
instead of a tenancy as provided herein, and Tenant shall give to Landlord at
least thirty (30) days prior written notice of any intention to remove from the
Premises, and shall be entitled to ten (10) days prior notice of any intention
of Landlord to remove Tenant from the Premises in the event Landlord desires
possession of the Premises; provided, however, that said tenant-at-sufferance
shall not be entitled to ten (10) days notice in the event the said Rent is not
paid in advance without demand, the said ten (10) days written notice being
hereby expressly waived.

                                  ARTICLE XVII

                                REMEDIES/DAMAGES

         In the event Tenant is in default under this Lease as provided in
Article XVI, Landlord may elect, in addition to any and all remedies provided
by Florida Law, any or all of the following remedies:

         SECTION 17.1  TERMINATION OF LEASE.   By written notice to Tenant,
designate a date upon which the Lease shall terminate ("Termination Date"), and
thereupon, on the Termination Date, this Lease and all rights of Tenant
hereunder shall terminate. Such termination by Landlord shall not affect the
obligations of Tenant arising under the Lease prior to the Termination Date or
the other remedies of Landlord provided in this Lease.

         SECTION 17.2  TERMINATION OF TENANT'S POSSESSION.    Landlord may
elect to terminate Tenant's possessory rights, without terminating the Lease,
and upon such election, Tenant shall surrender the Premises to Landlord, and
Landlord, at any time after such termination, may, without further notice,
re-enter and repossess the Premises without being liable to any prosecution or
damages therefore, and no person claiming through or under Tenant or by virtue
of any statute or of any order of any court shall be entitled to possession of
the Premises. At any time or from time to time after any such termination of
Tenant's possession, Landlord may relet the Premises or any part thereof, in
the name of Landlord or otherwise, for such term or terms and on such
conditions as Landlord, in its


                                      17
<PAGE>   19

sole discretion, may determine, and may collect and receive the rents
therefore. Landlord shall not be responsible or liable for any failure to relet
the Premises or any part thereof or for any failure to collect any rent due
upon any such reletting. The termination of Tenant's possession shall not
relieve Tenant of its liability and obligations under this Lease, including the
obligation to pay Rent, and such liability and obligations shall survive any
such termination. Any Rent or other monetary obligation of Tenant that has been
abated, deferred or forgiven by Landlord in this Lease or any amendment
thereto, and the cost of all Tenant Improvements provided or paid for by
Landlord pursuant to Section 7.1 above, shall immediately become due and
payable upon the occurrence of an event of default by Tenant under this Lease.
If Landlord, at its option shall relet the Premises during said period,
Landlord shall credit Tenant with the net rents received by Landlord from such
reletting, such net rents to be determined by first deducting from the gross
rents, as and when received by Landlord, the expenses incurred or paid by
Landlord in terminating this Lease and in securing possession thereof, as well
as the expenses of reletting, including, without limitation, the alteration and
preparation of the Premises for new tenants, brokers' commissions, attorneys'
fees and all other expenses properly chargeable against the Premises and the
rental therefrom. It is hereby understood that any such reletting may be for a
period shorter or longer than the remaining Term of this Lease but in no event
shall Tenant be entitled to receive any excess of such net rents over the sum
payable by Tenant to Landlord hereunder, nor shall Tenant be entitled in any
suit for the collection of damages pursuant hereto to a credit in respect of
any net rents from a reletting, except to the extent that such rents are
actually received by Landlord.

         SECTION 17.3  DAMAGES.   Landlord may elect, whether this Lease or
Tenant's possession is terminated or not, to recover damages from the Tenant in
accordance with either of the following provisions:

         (a)   The present value of the entire amount of the Rent which would
become due and payable during the remainder of the Term of this Lease, in which
event Tenant agrees to pay the same at once, together with all Rent theretofore
due, at Landlord's address as provided herein; provided, however, that such
payment shall not constitute a penalty or forfeiture or liquidated damages, but
shall constitute payment in advance of the Rent for the remainder of the Term.
Such present value shall be determined utilizing a discount rate of six percent
(6%). The acceptance of such payment by Landlord shall not constitute a waiver
of any failure of Tenant thereafter occurring to comply with any term,
provision, condition or covenant of this Lease. If Landlord elects the remedy
given in this Section 173(a), then same shall be Landlord's sole remedy for
such default; or

         (b)   sums equal to the Rent which would have been payable by Tenant
in accordance with the Lease payable upon the due dates as set forth in the
Lease through the Expiration Date of this Lease.

Lawsuits for the recovery of such damages, or any installments thereof, may be
brought by Landlord from time to time at its election, and nothing contained
herein shall be deemed to require Landlord to postpone suit until the date when
the Term of this Lease would have expired, nor limit or preclude recovery by
Landlord against Tenant of any sums or damages which, in addition to the
damages particularly provided above, Landlord may lawfully be entitled by
reason or any default hereunder on the part of Tenant. All remedies of
Landlord provided for herein, or otherwise at law or in equity, shall be
cumulative and concurrent.

                                 ARTICLE XVIII

                                 EMINENT DOMAIN

         SECTION 18.1  TAKING.    If the whole of the Building or the Premises
or if a portion of the Building or the Premises which will materially and
adversely affect Tenant's use and occupancy of the Premises shall be taken by
condemnation or in any other manner for any public or quasi-public use or
purpose, this Lease shall terminate as of the date of vesting of title on such
taking (herein called "Date of Taking"), and the Base Rent and Additional Rent
shall be prorated and adjusted as of such date.


                                      18
<PAGE>   20

         SECTION 18.2  AWARD.    Landlord shall be entitled to receive the
entire award or payment in connection with any taking without deduction
therefrom; provided, however, Tenant shall be entitled to receive a separate
award attributable to its relocation costs and its tenant improvements so long
as any such separate award does not represent the value of the loss of the
Tenant's leasehold estate or otherwise reduce the amount of the award that
would have otherwise been made payable to Landlord.

         SECTION 18.3  TEMPORARY TAKING.  If the temporary use or occupancy of
all or any part of the Premises shall be taken by condemnation or in any other
manner for any public or quasi-public use or purpose during the Term of this
Lease, Tenant shall be entitled, except as hereinafter set forth, to receive
that portion of the award or payment for such taking which represents
compensation for the temporary use and occupancy of the Premises, for the
taking of Tenant's Property and for moving expenses, and Landlord shall be
entitled to receive all other award or payment, including, without limitation,
that portion which represents reimbursement for the cost of restoration of the
Premises. This Lease shall be and remain unaffected by such taking and Tenant
shall continue to pay the Rent in full when due. If the period of temporary use
or occupancy shall extend beyond the Expiration Date of this Lease, that part
of the award which represents compensation for the use and occupancy of the
Premises (or a part thereof) shall be divided between Landlord and Tenant so
that Tenant shall receive so much thereof as represents the period up to and
including such Expiration Date and Landlord shall receive so much as represents
the period after such Expiration Date. All monies received by Landlord as, or
as part of, an award for temporary use and occupancy for a period beyond the
date through which the Rent has been paid by Tenant, shall be held and applied
by Landlord as a credit against the Rent becoming due hereunder.

         SECTION 18.4  PARTIAL TAKING.    In the event of any taking of less
than the whole of the Building or Premises which does not result in termination
of this Lease, then: (a) subject to the prior rights of a Superior Mortgagee,
Landlord, at its expense, shall proceed with reasonable diligence to restore
the remaining parts of the Building and the Premises (other than those parts of
the Premises which are Landlord's property and Tenant's property) to
substantially their former condition to the extent that the same is feasible
(subject to reasonable changes which Landlord shall deem desirable), so as to
constitute a complete and tenantable Building and Premises; and (b) Tenant, at
its expense, shall proceed with reasonable diligence to restore the remaining
parts of the Premises which are deemed Landlord's Property and Tenant's
Property pursuant hereto, to substantially their former condition to the extent
feasible, subject to reasonable changes which Tenant shall deem desirable and
Landlord shall approve. Such work by Tenant shall be deemed alterations as
described in Section 11.1 hereinabove. In the event of any partial taking,
Tenant shall be entitled to a reduction in Rent for the remainder of the Lease
Term following such partial taking based upon the percentage of Premises taken
relative to the original Premises leased.

                                  ARTICLE XIX

                                QUIET ENJOYMENT

         SECTION 19.1  QUIET ENJOYMENT.  Landlord agrees that Tenant, upon
paying all Rent and all other charges herein provided for and observing and
keeping the covenants, agreements, terms and conditions of this Lease and the
rules and regulations of Landlord affecting the Premises on its part to be
performed, shall lawfully and quietly hold, occupy and enjoy the Premises
during the Term hereof, expressly subject to the terms, limitations and
conditions contained in this Lease.

                                   ARTICLE XX

                          SUBORDINATION AND ATTORNMENT

         SECTION 20.1  SUBORDINATION, ATTORNMENT AND NON-DISTURBANCE. This
Lease, and all rights of Tenant hereunder, are and shall be subordinate to any
mortgage, long-term lease or other encumbrance, whether now of record or
recorded after the date of this Lease, affecting the Premises, the Building or
the Property. Such subordination is self-operative without any further act of
Tenant. Any mortgage, long-term lease or other encumbrance to which this Lease
is subject and subordinate is


                                      19
<PAGE>   21

hereinafter referred to as a "Superior Mortgage", and the holder of a Superior
Mortgage is hereinafter referred to as a "Superior Mortgagee". If any Superior
Mortgagee shall succeed to the rights of Landlord hereunder, whether through
possession or foreclosure action or delivery of a new lease or deed, then, at
the request of such party (hereinafter referred to as "Successor Landlord"),
Tenant shall attorn to and recognize such Successor Landlord as Tenant's
Landlord under this Lease and shall promptly execute and deliver any instrument
such Successor Landlord may reasonably request to evidence such attornment.
Upon such attornment, this Lease shall continue in full force and effect as a
direct Lease between Successor Landlord and Tenant, upon all terms, conditions,
and covenants as set forth in this Lease, except that the Successor Landlord
shall not: (a) be liable for any previous act or omission of Landlord under
this Lease; (b) be subject to any offset; or (c) be bound by any previous
modification of this Lease or by any previous prepayment, unless such
modification or prepayment shall have been previously approved in writing by
such Successor Landlord if such approval was required. Further, upon such
attornment, Landlord shall be released from any further obligation hereunder.
Tenant shall, within ten (10) days of a request by Landlord, execute and
deliver any documents or instruments that may be required by Superior Mortgagee
or Landlord to confirm such subordination or Attornment. So long as Tenant is
not in default under this Lease, Tenant's possession of the Premises and
Tenant's rights and privileges under this Lease shall not be diminished or
interfered with by any Successor Landlord during the term of this Lease. This
particular provision shall be binding upon any assigns or successors in
interest to Landlord. Notwithstanding the subordination and attornment of this
Lease to any Superior Mortgagee which presently exists or which may hereafter
be made, or to any renewal, modification, replacement or extension hereafter of
any Superior Mortgagee, such Superior Mortgagee, by separate recordable
agreement, shall agree that so long as this Lease is in effect and not in
default, Tenant's leasehold interest under this Lease shall not be terminated
or disturbed. Such non-disturbance agreement shall also include subordination
and attornment provisions satisfactory to Superior Mortgagees.

         SECTION 20.2  NOTICE TO LANDLORD AND SUPERIOR MORTGAGEE.    If any act
or omission of Landlord would give Tenant the right, immediately or after the
lapse of a period of time, to cancel this Lease or to claim a partial or total
eviction, Tenant shall not exercise such right; (a) until it has given written
notice of such act or omission to Landlord and any Superior Mortgagee; and (b)
until a reasonable period of time (not to exceed 30 days) for remedying such
act or omission shall have elapsed following the giving of such notice and
following the time when such Superior Mortgagee shall have become entitled
under such Superior Mortgage to remedy the same. In the event any Superior
Mortgagee shall request reasonable modifications to this Lease as a condition
to financing or refinancing, Tenant shall not withhold, delay or defer in
providing its consent thereto, unless such Lease modifications decrease the
area of the Premises, increase the Rent owed under this Lease, or materially
affect Tenant's use and enjoyment of the Premises in an adverse manner. In the
event Tenant has not provided its consent to modifications requested by a
Superior Mortgagee within ten (10) days after written notice from Landlord,
Landlord, at its sole option, shall have the right to either terminate this
Lease, or to execute any instrument for and on behalf of Tenant as its
attorney-in-fact. In acknowledgment thereof, Tenant hereby appoints Landlord as
its irrevocable attorney-in-fact for the purpose of executing any instruments
required to carry out the intent of this Section on behalf of Tenant after
proper notice, and default hereunder by Tenant.

                                   ARTICLE XXI

                           LANDLORD'S RIGHT OF ACCESS

         SECTION 21.1 ACCESS FOR MAINTENANCE AND REPAIR. Except for the space
within the inside surfaces of all walls, hung ceilings, floors, windows, and
doors bounding the Premises, all of the Building including, without limitation,
exterior walls, core interior walls and doors and any core corridor entrance,
any terraces or roofs adjacent to the Premises, and any space in or adjacent to
the Premises used for shafts, stacks, pipes, conduits, fan rooms, ducts,
electric or other utilities, sinks, or other facilities of the Building, and
the use thereof, as well as access thereto throughout the Premises for the
purposes of operation, maintenance, decoration and repair, are reserved to
Landlord. Landlord reserves the right, and Tenant shall permit Landlord, to
install, erect, use and maintain pipes, ducts and conduits in and through the
Premises. Landlord shall be allowed to take all materials into and upon the
Premises that may be required in connection therewith, without any liability to
Tenant and without any


                                      20
<PAGE>   22


reduction of Tenant's covenants and obligations hereunder. Landlord and its
agents shall have the right to enter upon the Premises for the purpose of making
any repairs therein or thereto which shall be considered necessary or desirable
by Landlord, in such a manner as not to unreasonably interfere with Tenant in
the conduct of Tenant's business on the Premises. Except in the case of
emergency, Landlord shall provide Tenant with 48 hours prior written notice
before entering the Premises.

         SECTION 21.2  ACCESS FOR INSPECTION AND SHOWING. Upon reasonable
notice to Tenant and during normal business hours, Landlord and its agents
shall have the right to enter and/or pass through the Premises at any time to
examine the Premises and to show them to prospective purchasers, mortgagees or
lessees of the Building. During the period of four (4) months prior to the
Expiration Date of this Lease, Landlord and its agents may exhibit the Premises
to prospective tenants.

         SECTION 21.3  LANDLORD'S ALTERATIONS AND IMPROVEMENTS. If, at any
time, any windows of the Premises are temporarily darkened or obstructed by
reason of any repairs, improvements, maintenance and/or cleaning in or about
the Building, or if any part of the Building, other than the Premises, is
temporarily or permanently closed or inoperable, the same shall be without
liability to Landlord and without any reduction or diminution of Tenant's
obligations under this Lease; provided however, Landlord shall use its best
efforts to minimize the duration of such darkening or obstruction. Landlord
reserves the right to make such changes, alterations, additions, and
improvements in or to the Building and the fixtures and equipment thereof, as
well as in or to the street entrances, doors, halls, passages, elevators,
escalators and stairways thereof, and other public portions of the Building and
the Property, as Landlord shall deem necessary or desirable, and no such
alterations or changes shall be deemed a breach of Landlord's covenant of quiet
enjoyment or a constructive eviction.

placed or maintained upon any exterior door, roof, wall or window of the
Premises or the Building, any sign, awning, canopy or advertising matter of any
kind, nor place or maintain any decoration, lettering or advertising matter on
the glass of any window or door of the Premises, except as previously approved
in writing by Landlord, in Landlord's sole discretion. Tenant shall not place
or maintain any freestanding sign within or upon the Common Area of the
Premises or the Building or immediately adjacent thereto, without first
obtaining Landlord's express prior written consent. No interior or exterior
sign visible from the exterior of the Building shall be permitted. Tenant
further agrees to maintain any such signage approved by Landlord in good
condition and repair at all times and to remove the same at the end of the Term
of this Lease if requested by Landlord. Upon removal thereof, Tenant agrees to
repair any damage to the Premises caused by such installation and/or removal.
Notwithstanding the foregoing, subject to Landlord's prior written approval of
the plans and specifications for same, Tenant shall have the right to install
prominent signage in Tenant's reception area.

         SECTION 22.2  OBSTRUCTION. Tenant shall not obstruct the corridors,
elevators, stairs, common areas, sidewalks, parking lots or other public
portions of the Building or the Property in any manner whatsoever.

                                  ARTICLE XXIV

                                 MISCELLANEOUS

         SECTION 24.1  SUBSTITUTE PREMISES.

                             INTENTIONALLY DELETED

         SECTION 24.2  ENVIRONMENTAL INDEMNITY. Tenant agrees to indemnify and
hold Landlord harmless from and against any and all loss, claim, liability,
damages, injuries to person, property, or natural resources, cost, expense,
action or cause of action, arising in connection with the release or presence
of any "Hazardous Substances" at the Premises, through the acts of Tenant, its
officers, employees, contractors, agents or invitees, whether foreseeable or
unforeseeable, regardless of the source of such release and when such release
occurred or such presence is discovered. The foregoing indemnity includes,
without limitation, all costs in law or in equity of removal, remediation of
any kind, and disposal of such Hazardous Substances; all costs of determining
whether the Premises is in compliance and to cause the Premises to be in
compliance with all applicable environmental laws, all costs associated with
claims for damages to persons, property, or natural resources, and Landlord's
reasonable attorneys' and consultants' fees and costs, whether or not
litigation is instituted. For the purposes of definition, Hazardous Substances
includes, without limitation, any toxic or hazardous wastes, pollutants or
substances, including, without limitation, asbestos, PBCs, petroleum products
and by-products, substances defined or listed as "hazardous substances" or
"toxic substances" or similarly identified in or pursuant to the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, 42
U.S.C. Section 9061 et. seq., or as identified in or pursuant to the Hazardous
Materials Transportation Act 49 U.S.C. Section 1902 et seq.

         SECTION 24.3  RADON GAS.   Pursuant to Florida Statutes, Section
404.056[7], the following disclosure is required by law: 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 that exceed federal and state guidelines have
been found in buildings in Florida. Additional information regarding Radon and
radon testing may be obtained from your county public health unit.

         SECTION 24.4  BROKER COMMISSION. Landlord and Tenant-covenant, warrant
and represent that Stiles Realty Co. and Florida Corporate Realty, Inc.
(hereinafter collectively referred to as "Brokers") were instrumental in
bringing about or consummating this Lease. Further, neither Landlord nor Tenant
have had any conversations or negotiations with any broker except those Brokers
concerning the leasing of the Premises. Both parties agree to indemnify the
other against and from any claims for any brokerage commissions (except those
payable to Brokers) and all costs, expenses and


                                      22
<PAGE>   24
liabilities in connection therewith, including, without limitation, reasonable
attorneys' fees and expenses, for any breach of the foregoing representation.
Landlord shall pay all brokerage commissions due Brokers in accordance with a
separate agreement between Landlord and Broker.

         SECTION 24.5  ESTOPPEL CERTIFICATES. Each party agrees, at any time and
from time to time as requested by the other party, to execute and deliver to
the other a statement certifying that this Lease is unmodified and in full force
and effect (or if there have been modifications, that the same are in full force
and effect as modified and stating the modifications), certifying the dates to
which the Base Rent and Additional Rent have been paid, stating whether or not
the other party is in default in performance of any of its obligations under
this Lease, and, if so, specifying each such default, and stating whether or not
any event has occurred which, with the giving of notice or passage of time, or
both, would constitute such a default, and, if so, specifying each such event.
Tenant also shall include in any such statements such other information
concerning this Lease as Landlord, its mortgagee or purchaser may reasonably
request. In the event either party fails to comply with this Section, such
failure shall constitute a material breach of the Lease.

         SECTION 24.6  NO RECORDATION.   This Lease shall not be recorded by
Tenant in the Public Records of Broward County, Florida. Any attempted
recordation by Tenant shall render this Lease null and void and entitle Landlord
to the remedies provided for Tenant's default. At the request of Landlord,
Tenant shall promptly execute, acknowledge and deliver to Landlord a Memorandum
of Lease with respect to this Lease, and a Memorandum of Modification of Lease
with respect to any modification of this Lease, prepared by Landlord and
sufficient for recording. Such Memorandum shall not be deemed to change or
otherwise affect any of the obligations or provisions of this Lease.

         SECTION 24.7  GOVERNING LAW.    This Lease shall be governed by and
construed in accordance with the laws of the State of Florida, and in the event
litigation arises between the Parties in connection with any of the terms of
this Lease, venue shall lie in the Circuit Court in Broward County, Florida, or
in the Federal District Court for the Southern District of Florida. If any
provision of this Lease or the application thereof to any person or circumstance
shall, for any reason and to any extent, be invalid or unenforceable, the
remainder of this Lease shall remain in full force and effect. The table of
contents, captions, headings and titles in this Lease are solely for convenience
of reference and shall not affect its interpretation. This Lease shall be
construed without regard to any presumption or other rule requiring construction
against the party causing this Lease to be drafted. Each covenant, agreement,
obligation, or other provision of this Lease on Tenant's part to be performed,
shall be deemed and construed as a separate and independent covenant of Tenant,
not dependent on any other provision of this Lease. All terms and words used in
this Lease, regardless of the number or gender in which they are used, shall be
deemed to include any other number and any other gender, as the context may
require.

         SECTION 24.8  NO PARTNERSHIP OR JOINT VENTURE.  Nothing contained in
this Lease will be deemed or construed to create a partnership or joint venture
between Landlord and Tenant, or to create any other relationship between the
parties other than that of Landlord and Tenant.

         SECTION 24.9  APPROVAL BY SUPERIOR MORTGAGEE. If required by a Superior
Mortgagee, this Lease shall not become binding upon Landlord until approval of

most current financial information specified above to Landlord upon ten (10)
days written notice from Landlord.

         SECTION 24.11 CAPACITY TO EXECUTE LEASE. If Tenant is other than a
natural person, Tenant represents that it is legally constituted, in good
standing and authorized to conduct business in the State of Florida. Tenant
further represents that the person who is executing this Lease on its behalf has
the full power and authority to perform such execution and deliver the Lease to
Landlord, and that


                                      23
<PAGE>   25

upon such execution and delivery, the Lease shall be valid and binding upon
Tenant in accordance with its respective terms and conditions. To further
evidence the foregoing, upon request by Landlord, Tenant shall deliver to
Landlord an appropriate corporate or partnership resolution specifying that the
signatory to the Lease has been duly authorized to execute same on behalf of
Tenant, and a Certificate of Good Standing from the State of Florida if Tenant
is anything other than a natural person or a general partnership.

         SECTION 24.12 EXCULPATION OF LANDLORD.  Landlord's obligations and
liability to Tenant with respect to this Lease shall be limited solely to
Landlord's interest in the Property, and neither Landlord nor any of the
partners of Landlord, nor any officer, director, or shareholder of any of the
partners of Landlord, shall have any personal liability whatsoever with respect
to this Lease.

         SECTION 24.13 WAIVER OF TRIAL BY JURY.    IT IS MUTUALLY AGREED BY AND
BETWEEN LANDLORD AND TENANT THAT THE RESPECTIVE PARTIES HERETO SHALL, AND THEY
HEREBY DO, WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM

OR IN ANY WAY CONNECTED WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND
TENANT OR TENANT'S USE OR OCCUPANCY OF THE PREMISES, OR BY ANY COURSE OF
CONDUCT OR COURSE OF DEALING.

         SECTION 24.14 SATELLITE ANTENNA. Tenant shall have the non-exclusive
right to place a satellite antenna on the roof of the Building at Tenant's sole
cost and expense. The location, size, method of installation and wiring of said
antenna shall be subject to Landlord's prior written approval and shall also be
subject to any other approval rights in other leases within the Building
pertaining to satellite antennae. Tenant will be responsible for any electric
costs associated with such antenna. Upon the expiration or earlier termination
of this Lease, if requested by Landlord, Tenant shall remove the antenna and
repair any damage to the roof of the Building resulting from such installation
or removal thereof.

         SECTION 24.15 CONSENT. Where either party's consent shall be required
in this lease, such consent shall not be unreasonably withheld, conditioned,
delayed or denied.

         SECTION 24.16 ENTIRE AGREEMENT.  This Lease constitutes the entire
understanding between the parties and shall bind the parties, their successors
and assigns. No representations, except as herein expressly set forth, have
been made by either party to the other, and this Lease cannot be amended or
