     2.  Term:  The term of this Lease shall commence on July 20, 1996, which
shall be the date upon which substantial completion and acceptance by Tenant of
the Tenant improvements as described herein have been made (hereinafter referred

six (36) months following the Commencement Date.  Notwithstanding the foregoing,
Tenant shall be entitled to immediate physical occupancy of temporary space as

possession of the Lease Premises on the Commencement Date due to any act,
neglect, fault or omission of Landlord or any of his partners, officers,
employees, agents, representatives, contractors or trustees, or Tenant
Improvements are not completed to Tenant's satisfaction which shall not be
unreasonable, the Commencement Date shall be postponed by the number of days of
such delay.  In the event of a delay in excess of thirty (30) days in the
Commencement Date, Tenant shall have the right but not the obligation to
terminate this Lease.

     3.  Rent:

     4.  Tenant's Tenant Improvements: Landlord has agreed, at its sole expense,
to make certain improvements in and to the Lease Premises subject to the
conditions contained herein, and to the plans and specifications in the Exhibit
"A" attached hereto and incorporated herein.  Promptly after the execution of
this Lease, Landlord shall commence and thereafter complete with due diligence
its construction work and installation of fixtures in accordance with Exhibit

respect to the work done by Landlord or on Tenant's behalf that may be required

permits, licenses, fees, and meters and shall comply with all codes, ordinances
and regulations in performing the Tenant improvements required herein.  Landlord

evidence of insurance coverage as required by statute relative to the class of
contractors's license held.  This evidence of insurance shall include Workman's

the construction operations, offices and storage to the Lease Premises only and
shall remove all trash, rubbish and surplus material from the project at such
time to prevent trash accumulation.
 
     5.  Deposit - Upon execution of this Lease, there shall be due and payable
by Tenant a deposit in an amount equal to one month's rent in order to secure
the performance by Tenant of all covenants, conditions, obligations and
undertakings required of Tenant under the Lease.  It is expressly understood
that the deposit shall not be considered an advance payment of base rental or a
measure of Landlord's damages in case of default by Tenant.  Upon the occurrence
of any event of default with respect to Tenant's obligations under the Lease,
Landlord may, after having given Tenant ten (10) days written notice and without
prejudice to any other remedy, use the deposit to the extent necessary to make
good any such default caused by Tenant, or any other charges, damage, injury,
expense or liability caused to Landlord by the event of Tenant's default.

     6.  Repairs and Maintenance.

         A.  Landlord shall maintain the parking lot, roof, foundation, 
including plumbing located within the foundation slab, and the structural
soundness of the exterior walls (excluding all windows, window glass, plate
glass and all doors) of the building and Lease Premises in good repair and
condition except for reasonable wear and tear. Tenant shall repair and pay for
any damage including those repairs which are the responsibility of Landlord,
caused by any negligence or intentional act or omission of Tenant or Tenant's
agents, employees and invitees. Tenant shall immediately give written notice to
Landlord of the need for repairs, which repairs shall be made by Landlord at
Landlord's cost beginning not more than fifteen (15) days after written notice
by Tenant.

 
         1.  Landlord shall, at its own expense, maintain all other parts of the
Lease Premises in good repair and condition (including all necessary
replacements), including, but not limited to, the Heating Ventilation Air
Cooling Systems ("HVAC"), downspout, fire sprinkler system and lavatories.
Tenant shall take good care of the Lease Premises and its fixtures.  
<PAGE>
 
Should Tenant neglect to keep and maintain the Lease Premises, reasonable wear
and tear excepted, then Landlord after having given Tenant written notice and
thirty (30) days to comply, shall have the right, but not the obligation, to
have the work done and the costs shall be charged to Tenant as additional rent
and shall become payable by Tenant with the payment of Rent next due hereunder.

         2.  Landlord shall provide Tenant, during the term of this Lease and 
any renewal hereof, with the duplicate original of a maintenance contract with a
reputable HVAC maintenance firm in the form and substance acceptable to Tenant.
Should the Landlord fail to provide Tenant with the duplicate original of
maintenance contract within forty-five (45) days from the Commencement Date,
Tenant shall have the option not the obligation, to obtain on behalf of the
Landlord, a maintenance contract. The cost of such contract shall become payable
by Landlord immediately upon notice by Tenant.

         3.  Tenant shall not allow any damage to be committed on any portion 
of the Lease Premises. Tenant shall deliver the Lease Premises to Landlord in as
good condition as existed at the Commencement Date of this Lease, ordinary wear
and tear excepted. The cost of any repairs necessary to restore the condition of
the Lease Premises shall be borne by Tenant, and if Landlord undertakes to
restore the Lease Premises it shall have a right of reimbursement against Tenant
which right shall survive the termination of this Lease.

     7.  Utility Service.  Landlord shall provide the normal utility service
connections into the Lease Premises.  Tenant shall pay the cost of all utility
services, including all charges for gas, water and electricity and janitorial
service used in the Lease Premises.

be paid from the Advance Rent as described in Section 34 of this Lease.

     9.   Usage.  Tenant warrants and represents to Landlord that the Lease
Premises shall be used and occupied solely for general office use.

     10.  Compliance With Laws, Rules and Regulations.  Tenant, shall, at its
sole cost and expense, comply with all of the requirements of all municipal,
state and federal authorities now in force, or which may hereafter be in force,
pertaining to the Lease Premises, and shall faithfully observe in the use of the
Lease Premises all municipal ordinances and state and federal statutes now in
force or which may hereafter be in force.  Notwithstanding the foregoing, Tenant
shall not be responsible for compliance with the American Disability Act, or any
similar laws.  Landlord warrants that the Lease Premises complies with the
requirements of all municipal ordinances and State and Federal Statutes now in
force.  The judgment of any court of competent jurisdiction, or the admission by
Tenant in any action or proceeding that Tenant has violated any such ordinance
or statute pertaining to the Lease Premises, shall be conclusive of that fact as
between Landlord and Tenant.
<PAGE>
 
     11. Insurance.

         A.  Tenant shall not permit the Lease Premises to be used in any way 
which would, in the opinion of Landlord, be extra hazardous on account of fire
or otherwise which would in any way increase or render void the fire insurance
on leasehold improvements. If at any time during the term of this Lease the Sate
Board of Insurance or other insurance authority disallows any of the Landlord's
credits or imposes an additional penalty or surcharge in Landlord's insurance
premiums because of Tenant's original or subsequent use of the Lease Premises or
any other act of Tenant, Tenant agrees to pay as additional Rents the increase
in Landlord's insurance premiums.

         B.  Tenant shall obtain and maintain in force throughout the term of 
this Lease general public liability insurance in the amount of $100,000.00 /
$300,000.00. Said policy shall name both Landlord and Tenant as insured (with a
cross-liability endorsement), shall be issued by an insurance company or
companies authorized to do business in the State of Florida, shall be issued as
a primary policy and shall contain a provision requiring the insurer to give
Landlord at least thirty (30) calendar days prior written notice before any
termination or expiration of said policy for any reason. Prior to the
commencement of this Lease and prior to the expiration of the term of each such
policy, Tenant shall deliver to Landlord the original of such a policy or proper
certificate from the insurer.

         C.  Landlord shall, at all times during the term of this Lease, 
maintain and pay for a policy or policies of insurance with the premiums paid in
advance, issued by and binding upon some solvent insurance company, insuring the
Lease Premises against all risk of direct physical loss in an amount Landlord
deems appropriate; provided that Landlord shall not be obligated in any way or
manner to insure any personal property (including, but not limited to, any
furniture, machinery, goods or supplies) of Tenant or which Tenant may have upon
or within the Lease Premises or any fixtures installed by or paid for by Tenant
upon or within the Lease Premises or any additional improvements which Tenant
may construct on the Lease Premises.

         D.  Tenant shall maintain in full force and effect on all of its 
fixtures and equipment in the Lease Premises, a policy or policies of fire
insurance with extended coverage endorsement to the extent of replacement value
required to negate the effect of a co-insurance provision. Said policy shall be
issued by an insurance company or companies authorized to do business in the
State of Florida. Landlord shall have no interest in the insurance upon Tenant's
equipment and fixtures.

     12. Taxes.  Tenant shall pay, before they are delinquent, all taxes levied
or assessed on Tenant's fixtures, equipment and personal property in and on the
Lease Premises, whether or not affixed to the real property.  If at any time
after any tax or assessment has become due or payable, Tenant neglects to pay
such tax or assessment, Landlord shall be entitled to pay the delinquent tax or
assessment at any time thereafter and such amount shall be deemed to be
additional Rent for the Lease Premises due and payable by Tenant at the time of
the next following monthly Rent payment.
<PAGE>
 
     13. Waiver of Subrogation.  Anything in this Lease to the contrary
notwithstanding, Landlord and Tenant hereby waive and release each other of and
from any and all rights of recovery, claim, action or cause of action, against
each other, their agents, officers and employees, for any loss or damage that
may occur to the Lease Premises, improvements to the Lease Premises or personal
property (building contents) within the Lease Premises, by reason of fire or the
elements regardless of cause or original, including negligence of Landlord or
Tenant and their agents, officers and employees, provided such losses are
covered by insurance.  Because this paragraph will preclude the assignment of
any claim mentioned in it by way of subrogation or otherwise to an insurance
company or any other person, each party to this Lease agrees immediately to give
notice to each insurance company which has issued to it policies of insurance
covering all risk of direct physical loss, and to have the insurance policies
properly endorsed, if necessary, to prevent the invalidation of the insurance
coverage by reason of the mutual waivers contained in this paragraph.

     14. Alterations and Improvements.  Tenant shall not make or allow to be
made any alterations or physical additions in or to the Lease Premises without
first obtaining the written consent of Landlord, which consent shall not be
unreasonably withheld.  Any alterations, physical additions or improvements to
the Lease Premises made by Tenant shall at once become property of Landlord and
shall be surrendered to Landlord upon the termination of this Lease.  This
clause shall not apply to movable equipment or furniture owned by Tenant which
may be removed by Tenant at the end of the term of this Lease, if Tenant is not
then in default and if such equipment and furniture is not then subject to any
other rights, liens and interests of Landlord.

     15. Mechanic's Liens.  No work performed by Tenant whether in the nature
of erection, construction, alteration or repair, shall bee deemed to be for the
immediate use and benefit of Landlord.  No mechanic's or other lien shall attach
to or be allowed to stand against the estate of Landlord by reason of any
improvements made by Tenant or at the request or direction of Tenant.  Tenant
shall pay promptly all persons furnishing labor or materials with respect to any
work performed by Tenant or its contractor(s) in, on or about the Lease
Premises.  In the event any mechanic's or other lien shall at any time be filed
against the Lease Premises or the Commercial Center by reason of work, labor,
services or materials performed or furnished, or alleged to have been performed
or furnished, to Tenant or to anyone holding the Lease Premises through or under
Tenant, Tenant shall cause the same to be discharged of record or bonded to the
satisfaction of Landlord.  If Tenant shall fail to cause such lien to be so
discharged or bonded after being notified of the filing thereof, then in
addition to any other right or remedy of Landlord, Landlord may discharge the
same by paying the amount claimed to be due, and the amount so paid by Landlord
(including actual attorney's fees and expenses incurred by Landlord either
defending against such lien or in procuring the discharge of such lien),
together with interest thereon, shall be due and payable by Tenant to Landlord
as additional Base Rental.  Nothing herein contained shall be construed as a
consent by Landlord for Tenant to make any alterations, improvements,
installations or additions so as to give rise to any right to any laborer or
materialman to file any mechanic's lien or any notice thereof, or any other lien
purporting to affect Landlord's property or the Commercial Center.

this Lease, any of the Lease Premises is taken for any public or quasi-public
use under any governmental law, ordinance or regulation, or by right of eminent

authority or upon the vacating of the Lease Premises by the Tenant.
