     THIS LEASE (the "Lease"), dated the 12th day of September, 1994 is made 
between New World Partners Joint Venture, a Florida general partnership (the
"Landlord"), and Ross White Enterprises, d/b/a National Computer Distributors,
a Florida corporation (the "Tenant").

                   ARTICLE 1.  TERM AND CONSTRUCTION.

     1.1   Grant. Subject to the terms of this Agreement, and in consideration 
of the performance by the Tenant of its obligations under this Lease, the 
Landlord leases to the Tenant, and the Tenant leases from the Landlord, for 
the Term, the "Premises," which Premises are shown outlined on the floor plan 
attached hereto and made a part hereof as Exhibit "A".  The Premises are to be
located in that certain building to be constructed by the Landlord in Beacon 
Centre (the "Building"), located in Dade County, Florida, as more particularly
described in Exhibit "B," attached hereto and made a part hereof.

     1.2   Term.

           1.2.1  The "Term" of this Lease is the period from the Commencement 
Date, through and including the Expiration Date.  The Commencement Date shall
be deemed the earlier of the date upon which (a) the Landlord obtains a
Certificate of Occupancy; or (b) the Tenant takes possession of the Premises;
or (c) if ANF is selected as the Contractor (pursuant to Exhibit "D"), the date
which is one and one-half (1 and 1/2) months from the date which Landlord
permits ANF to commence and diligently pursue construction of "Tenant
Improvements" (as subsequently defined).  Subject to the provisions of Section
1.2.4, if no default has occurred on the part of the Tenant under this Lease,
then Landlord agrees to reimburse the Tenant for any "Holdover Penalty"
(subsequently defined) incurred by the Tenant, for, and attributable to, the
period from November 1, 1994 until, and including, December 31, 1994; provided,
however, that the Landlord shall not be required to reimburse the Tenant for
any amount(s) singularly or in the aggregate in excess of $10,000 per month. 
For purposes of the Lease, "Holdover Penalty" means the penalty in excess of
rent and other items payable by the Tenant under the Tenant's existing lease
for the premises located at 3401C NW 72 Ave, Miami, FL 33122 (the "Existing
Premises") as the result of the Tenant continuing to maintain possession of the
Premises beyond the term or renewal term of such lease.

           1.2.2  Subject to the provisions of Sections 1.2.4 and 1.2.6, if no 
default has occurred on the part of the Tenant under this Lease, and if the
Commencement Date does not occur on or before the date which is five (5) months
from the Date of Lease Execution (the "Holdover Payment Date"), then, Landlord
agrees to reimburse the Tenant for any Holdover Penalty incurred by the Tenant
and attributable to the period commencing immediately after the Holdover
Payment Date and continuing until, but not including, the Commencement Date.

           1.2.3  Subject to the provisions of Sections 1.2.4 and 1.2.6, if no 
default has occurred on the part of the Tenant under this Lease, and if the
Commencement Date does not occur on or before the date which is eight (8)
months from the Date of Lease Execution (the "Build-out Period"):

     (a)  the Tenant may terminate this Lease by providing the Landlord with 
     notice of such termination within fifteen (15) days of the expiration of
     such eight (8) month period, effective upon receipt by the Landlord of
     such notice of termination and the parties shall be relieved of all
     obligations set forth under this Lease, except for those obligations which
     survive the termination of this Lease; and

     (b)  the Landlord agrees to reimburse the Tenant for any Holdover Penalty 
     incurred by the Tenant within, and attributable to a period of no longer
     than, 90 consecutive days immediately after the expiration of the
     Build-out Period; provided, however, that the Landlord shall not be
     required to reimburse the Tenant for any amount(s) singularly or in the
     aggregate in excess of $10,000 per month.



                                    1
<PAGE>   5

Notwithstanding the foregoing provisions of Section 1.2.1, 1.2.2 and 1.2.3, if
delivery of possession or obtaining of a Certificate of Occupancy is delayed
due to: (a) any act or omission of the Tenant, then the Commencement Date shall
be the date the Landlord would have delivered possession or obtained a
Certificate of Occupancy, but for the Tenant's act or omission; or (b) any act
of God, labor dispute, materials shortage, or other circumstance beyond the
Landlord's reasonable control (collectively, "Force Majeure"), then the
Holdover Payment Date and the Build-out Period shall be extended by an amount
of time equal to the delay caused by such an event.

           1.2.4  Notwithstanding Sections 1.2.1 and 1.2.2 to the contrary, at 
any time after the Holdover Payment Date, if Landlord reasonably believes that
it will not be able, or has not been able, to Substantially Complete
(subsequently defined) and deliver the Premises within the Build-out Period,
then the Landlord may terminate this Lease by delivering notice to the Tenant
of such termination ("Notice of Termination").  Upon delivery of the Notice of
Termination, the Landlord shall thereupon reimburse the Tenant (promptly upon
Tenant's demand and after the Tenant delivers proof of payment to Landlord) for
any Holdover Penalty; provided, however, Landlord's liability shall not exceed
$10,000 per month and shall be limited to a period not exceeding one hundred
twenty (120) days from the date of the Notice of Termination.

           1.2.5  Landlord shall exercise reasonable efforts to give Tenant 
five days' prior notice of the proposed final inspection date for the Premises
by Dade County in connection with the issuance of a Certificate of Occupancy,
in order to provide Tenant with prior notice of a proposed Commencement Date.

           1.2.6  If the Tenant selects a contractor other than Codina 
Construction, Inc. to perform the work set forth in Exhibit C, the Landlord
shall have no obligation to pay any amounts due to Tenant under Sections 1.2.2
through 1.2.4, inclusive, or otherwise, and the Tenant shall have no right to
terminate this Lease by reason of the Landlord's failure to substantially
complete the Premises by a particular date, notwithstanding any provision to
the contrary.

     1.3   Construction.  The Landlord shall have no construction or 
improvement obligations with respect to the Premises except as expressly set
forth in Exhibit C to this Lease.  The Tenant shall be conclusively deemed to
have accepted the Premises upon taking of possession; provided, however, that
the Tenant and Landlord may agree upon a "punch list" of minor items to be
completed after the Commencement Date.  Upon the expiration of fifteen (15)
business days following the Commencement Date, the Premises shall be
conclusively deemed to be accepted by the Tenant unless the Tenant shall have
given the Landlord specific written notice of any contended defects in the
Premises.

                            ARTICLE 2.  RENT.

     2.1   Covenant to Pay.  The Minimum Rent and "Additional Rent" 
(subsequently defined) (Minimum Rent and Additional Rent are sometimes referred
to as "Rent") shall be payable and shall begin to accrue on the date (the "Rent
Commencement Date") which is four (4) months from the Commencement Date.  The
term "Additional Rent" means all other sums, charges and expenses of any kind
(including, without limitation, reasonable attorneys' fees and costs), which
are or may become due and payable to the Landlord under this Lease.  The Tenant
shall pay to the Landlord all sums due hereunder from time to time from the
Rent Commencement Date without prior demand, together with all applicable
Florida sales tax, use tax or other similar tax thereon; however, unless
otherwise provided in this Lease, payments other than the Tenant's regular
monthly payments of Minimum Rent and Operating Costs shall be payable by the
Tenant to the Landlord within five (5) days following demand, but in no event
later than the first day of the month after the month in which such Additional
Rent shall accrue.  All Rent or other charges that are required to be paid by
the Tenant to the Landlord shall be payable at the Landlord's address indicated
on the Lease Summary.  Minimum Rent and Additional Rent for any "Lease Year"
consisting of less than twelve (12) months shall be prorated on a per diem
basis, based upon a period of 365 days.  "Lease Year" means the twelve (12)
full calendar months commencing on the Commencement Date. However, the final
Lease


                                    2

<PAGE>   6

Year may contain less than twelve (12) months due to expiration or sooner
termination of the Term.  The Tenant agrees that its covenant to pay rent and
all other sums under this Lease is an independent covenant and that all such
amounts are payable without counterclaim, set-off, deduction, abatement, or
reduction whatsoever, except as expressly provided for in this Lease.

     2.2   Minimum Rent.  Minimum Rent for the period commencing on the Rent 
Commencement Date and ending two months thereafter (the "Prepaid Rent Period")
shall be due and payable upon the execution and delivery of this Lease by the
Tenant.  Upon expiration of the Prepaid Rent Period, payments of Minimum Base
Rent shall be due and payable in advance on the first day of each and every
month thereafter, subject to adjustment as set forth in the Lease Summary;
provided, however, if the Prepaid Rent Period expires on other than the last
day of a calendar month, then, on or prior to the expiration of the Prepaid
Rent Period, the Tenant shall make a proportionate payment of Minimum Rent for
the remainder of such calendar month.  The parties acknowledge that no Rent
shall be due or payable during the first four (4) months of the Lease Term, as
set forth in item 12 of the Lease Summary; provided, however, on or before the
Commencement Date, the Tenant shall pay to the Landlord as Rent for such period,
an amount equal to any Holdover Penalty paid by the Landlord pursuant to
Section 1.2.1 for November and/or December 1994, which shall be in addition to
any other amounts payable by the Tenant under this Lease.

     2.3   Operating Costs.  The Tenant shall pay to the Landlord the Tenant's 
proportionate share of the amount by which the annual "Operating Costs"
(subsequently defined), for each calendar year exceed the Operating Costs
incurred during the Base Year specified in the Lease . Summary (i.e. 1995). 
Such excess is referred to for purposes of this Lease as the "Increased
Operating Costs." The Tenant's obligation to pay its proportionate share of
Increased Operating Costs shall commence as of the beginning of the first full
calendar year following the Base Year.  The amount of Increased Operating Costs
payable to the Landlord may be estimated by the Landlord for such period as the
Landlord determines from time to time (not to exceed twelve (12) months), and
the Tenant agrees to pay to the Landlord the amounts so estimated in equal
installments, in advance, on the first day of each month during such period. 
Notwithstanding the foregoing, when bills for all or any portion of Increased
Operating Costs so estimated are actually received by the Landlord, the
Landlord may bill the Tenant for the Tenant's proportionate share thereof, less
any amount previously paid by the Tenant to the Landlord on account of such
item(s) by way of estimated Increased Operating Costs payments.

           Within a reasonable period of time after the end of the period for 
which estimated payments have been made, the Landlord shall submit to the
Tenant a statement from the Landlord setting forth the actual amounts payable
by the Tenant based on actual costs.  If the amount the Tenant has paid based
on estimates is less than the amount due based on actual costs, the Tenant
shall pay such deficiency within ten (10) days after submission of such
statement.  If the amount paid by the Tenant is greater than the amount
actually due, the excess may be retained by the Landlord to be credited and
applied by the Landlord to the next due installments of the Tenant's
proportionate share of Increased Operating Costs, or as to the final Lease
Year, provided the Tenant is not in default, the Landlord will refund such
excess to the Tenant.  The Tenant's proportionate share of actual Increased
Operating Costs for the final estimate period of the Term of this Lease shall
be due and payable even though it may not be finally calculated until after the
expiration of the Term.  Accordingly, the Landlord shall have the right to
continue to hold the Tenant's security deposit following expiration of the Term
until the Tenant's share of actual Increased Operating Costs has been paid.

           For purposes of this Lease, the Tenant's proportionate share shall 
be a fraction, the numerator of which shall be the gross rentable area of the
Premises, and the denominator of which shall be the "Gross Rentable Area"
(subsequently defined) of the Building.  For purposes of this Lease, the term
"Gross Leasable Area" means the amount of square feet constituting the actual
floor space of the Premises, including mezzanine space, measured to the
exterior faces of exterior walls and the center lines of any interior walls
constituting the boundaries of the Premises.  The term "Operating Costs" shall
mean any amounts paid or payable whether by the Landlord or by others on behalf
of the Landlord, arising out of the Landlord's maintenance, operation, repair,
replacement (if such replacement increases operating



                                    3

<PAGE>   7

efficiency) and administration of the Building and Common Areas, including,
without limitation: (i) the cost of all real estate, personal property and
other ad valorem taxes, and any other levies, charges, local improvement rates,
and assessments whatsoever assessed or charged against the Building and Common
Areas, the equipment and improvements therein contained, and including all
costs associated with the appeal of any assessment on taxes; (ii) the cost of
insurance which the Landlord is obligated or permitted to obtain under this
Lease and any deductible amount applicable to any claim made by the Landlord
under such insurance; (iii) the cost of security, (iv) the cost of landscaping,
and (v) a reasonable management fee (which shall be the greater of four percent
(4%) of Landlord's gross revenues under this Lease or such other fee as may be
charged from time to time as a management fee by any comparable facility). 
Operating Costs shall not include real estate commissions payable to brokers in
connection with Landlord's ordinary course of business.  If the Building is not
included in determining real property taxes for the year 1995, then,
notwithstanding "(i)" of the preceding sentence, Tenant shall not be
responsible for paying increases in real estate taxes until the calendar year
after the Building is included for purposes of determining the amount of real
estate taxes, and Tenant's liability for increases in real estate taxes shall
be calculated based upon increases over the amount of real estate taxes for the
first year in which the Building was included for purpose of determining real
property tax assessments.  For purposes of information only, as of the date of
this Lease, the Landlord charges a management fee of four percent (4%) of the
gross revenues received by the Landlord.

     2.4   Payment of Personal Property Taxes.  The Tenant shall pay, when due, 
all taxes attributable to the personal property, trade fixtures, business,
occupancy, or sales of the Tenant or any other occupant of the Premises and to
the use of the Building by the Tenant or such other occupant.

     2.5   Rent Past Due.  If any payment due from the Tenant shall not be paid 
when due, and within five (5) days of Landlord delivering notice to Tenant of
such delinquency (provided, however, that Landlord shall not be required to
provide such notice more than three (3) times during any calendar year), a late
charge of five (5%) percent of the delinquent sum may be charged by the
Landlord.  Such late charge is not a penalty, but liquidated damages to defray
administrative, collection, and related expense due to the Tenant's failure to
make such Rent payment when due.  If any payment due from the Tenant shall
remain overdue for more than fifteen (15) days, an additional late charge in an
amount equal to the lesser of the highest rate permitted by law or one and
one-half (1.5%) percent per month (eighteen percent (18%) per annum) of the
delinquent amount may be charged by the Landlord, such charge to be computed
for the entire period for which the amount is overdue and which shall be in
addition to and not in lieu of the five (5%) percent late charge or any other
remedy available to the Landlord. Notwithstanding the provisions of this
Section 2.5, the Landlord does not intend to charge and the Tenant shall not
pay interest or charges in the nature of interest which violate any applicable
usury law.  The provisions in this Section 2.5 for late charges are not, and
shall not be deemed, a grace period, except as expressly stated above.

     2.6   Security Deposit.  The Landlord acknowledges receipt of a security 
deposit in the amount specified on the Lease Summary to be held by the
Landlord, as security for the performance by the Tenant of all of its
obligations under this Lease.  The Landlord shall be entitled to commingle the
security deposit with the Landlord's other funds. If the Tenant defaults in
any of its obligations under this Lease, the Landlord may at its option, but
without prejudice to any other rights which the Landlord may have, apply all or
part of the security deposit to compensate the Landlord for any loss, damage,
or expense sustained by the Landlord as a result of such default.  If all or
any part of the security deposit is so applied, the Tenant shall restore the
security deposit to its original amount on demand of the Landlord.  Subject to
the provisions of Section 2.3, within thirty (30) days following termination of
this Lease, if the Tenant is not then in default, the security deposit, or
applicable portion thereof, will be returned by the Landlord to the Tenant,
together with interest thereon calculated on the basis of the passbook rate of
interest of Barnett Banks of South Florida, N.A. (or such other bank as
Landlord may select) during the Term of the Lease (as such rate may change from
time to time during the Term of the Lease).  If the Landlord transfers or
assigns the Landlord's interest under this Lease, the Landlord shall transfer
the security deposit to the transferee or assignee.



                                    4

Landlord shall also cause the new landlord to acknowledge receipt of the
deposit at the time of transfer.  Upon such transfer, the Landlord shall be
released by the Tenant from all liability for the return of the security
deposit, and the Tenant shall look solely to the new landlord for the return of
the security deposit.  The preceding sentence shall apply to every transfer or
assignment of the security deposit to a new landlord.  The Tenant shall not
transfer, assign, or encumber, or attempt to transfer, assign, or encumber the
moneys deposited as security and the Landlord shall not be bound by any such
actual or attempted transfer, assignment, or encumbrance.

     2.7   The Landlord's Lien.  To secure the payment of all Rent and other 
sums of money due and to become due hereunder and the faithful performance of
this Lease by the Tenant, the Tenant hereby give to the Landlord an express
first and prior contract lien and security interest on all property now or
hereafter acquired (including fixtures, equipment, chattels, and merchandise)
which may be placed in the Premises and also upon all proceeds of any insurance
which may accrue to the Tenant by reason of destruction of or damage to any
such property.  Such property shall not be removed therefrom without the
written consent of the Landlord until all arrearages in rental and other sums
of money then due to the Landlord hereunder shall first have been paid.  All
exemption laws are hereby waived in favor of said lien and security interest. 
This lien and security interest is given in addition to the Landlord's
statutory lien and shall be cumulative thereto.  The Landlord shall, in
addition to all of its rights hereunder, also have all of the rights and
remedies of a secured party under the Uniform Commercial Code as adopted in
the State of Florida. To the extent permitted by law, this Lease shall
constitute, a security agreement under Article 9 of the Florida Uniform
Commercial Code. Notwithstanding the foregoing, the Landlord agrees to
subordinate its lien to a bona fide institutional lender providing acquisition
financing or lease financing for the Tenant's furniture, fixtures, and
equipment, so that the Landlord will have a second lien on such furniture,
fixtures, and equipment.  The Landlord further agrees to execute and deliver
the subordination agreement attached to this Lease as Exhibit E.

                      ARTICLE 3.  USE OF PREMISES.

     3.1   Permitted Use.  The Premises shall be used and occupied only for the 
use specified in the Lease Summary and no other use.  Without limiting the
application of the foregoing sentence, the Tenant shall not use the Premises,
for other than warehouse for storage and distribution of computers and related
merchandise and ancillary office needs, in any manner which creates excessive
parking needs, or for the purpose of a telephone answering and order center. 
The Tenant shall carry on its business on the Premises in a reputable manner
and shall not do, omit, permit, or suffer to be done or exist upon the Premises
anything which shall result in a nuisance, hazard, or bring about a breach of
any provision of this Lease or any applicable municipal or other governmental
law or regulation.  The Tenant shall observe all reasonable rules and
regulations established by the Landlord from time to time for the Building. 
The rules and regulations in effect as of the date hereof are attached to and
made a part of this Lease as Exhibit "D." The names for the Building and the
business park of which the Building is a part, which the Landlord may from time
to time adopt, and every name or mark adopted by the Landlord in connection
with the Building shall be used by the Tenant only in association with the
business carried on in the Premises during the Term and the Tenant's use
thereof shall be subject to such regulation as the Landlord may from time to
time impose.

     3.2   Compliance with Laws.  The Premises shall be used and occupied in a 
safe, careful, and proper manner so as not to contravene any present or future
governmental or quasigovernmental laws, regulations, or orders, or the
requirements of the Landlord's or the Tenant's insurers.  If due to the
Tenant's use of the Premises, repairs, improvements, or alterations are
necessary to comply with any of the foregoing, the Tenant shall pay the entire
cost thereof.

     3.3   Signs.  Except with the prior written consent of the Landlord, the 
Tenant shall not erect, install, display, inscribe, paint, or affix any signs,
lettering, or advertising medium upon or above any exterior portion of the
Premises.  Any exterior signage shall be installed by the Landlord, or any
contractor approved by Landlord (such approval not to be unreasonably


                                    5

<PAGE>   9

withheld) at the Tenant's expense, and such signage shall comply with the
Landlord's sign criteria as adopted from time to time.  The design and
specification of such signage (including camera-ready artwork) shall be
submitted for the Landlord's prior written approval.

     3.4   Environmental Provisions.  The Tenant shall give written notice to 
the Landlord at least seven (7) days in advance of any production, generation,
handling, storage, treatment, transportation, disposal, release, or removal of
hazardous waste or hazardous substances from or on the Premises.  The Tenant
warrants and represents that it will not use or employ the Landlord's and/or
the Building property, facilities, equipment, or services to handle, transport,
store, treat, or dispose of any hazardous waste or hazardous substance, whether
or not it was generated or produced on the Premises; and the Tenant further
warrants and represents that any activity on or relating to the Premises shall
be conducted in full compliance with all applicable laws.  In addition, the
Landlord reserves the right to cause the Premises to be periodically inspected
by a reputable environmental consulting firm (upon two (2) business days' prior
notice to the Tenant, except that in the case of an emergency no such notice
shall be required); provided, however, such inspections shall not occur more
than twice during any calendar year and Tenant's costs shall not exceed five
hundred dollars ($500) per inspection, unless Landlord receives notice or has
reason to believe, that any hazardous waste or substance may have been
produced, generated, handled, stored, treated, disposed or released on, or
removed from, the Premises during the term of this Lease.  Except as limited in
the preceding sentence, the cost of such inspections, as well as the cost to
comply with such consultant's recommendations, shall be borne by the Tenant. 
The Tenant agrees to defend, indemnify, and hold harmless the Landlord against
any and all claims, costs, expenses (including, without limitation, reasonable
attorneys' fees and costs of any kind), damages, liability, and the like, which
the Landlord may hereafter be liable for, suffer, incur, or pay arising under
any applicable laws and resulting from or arising out of any breach of the
warranties and representations contained in this Section 3.4, or out of any
act, activity, or violation of any applicable laws on the part of the Tenant,
its agents, employees, or assigns.  The Tenant's liability under this Section
3.4 shall survive the expiration or any termination of this Lease.  The
Landlord shall provide the Tenant with a copy of the most recent environmental
report in the Landlord's possession and pertaining to the Leased Premises and
such other real property as may be referenced on such report.  The Landlord
shall take reasonable measures to assure that any environmental consultant
utilized by the Landlord to inspect the Premises shall have adequate insurance
coverage (as determined in the Landlord's reasonable judgment).  The Landlord
agrees to provide the Tenant with copies of any report rendered by such a
consultant, except when such a report is obtained in connection with pending or
anticipated litigation.
                                  
                      ARTICLE 4.  ACCESS AND ENTRY.

     4.1   Right of Examination.  The Landlord shall be entitled, upon 
reasonable notice (but no notice shall be required in emergencies), between 
8:00 a.m. and 6:00 p.m., Monday through Friday, to enter the Premises to
examine them; to make such repairs, alterations, or improvements thereto as the
Landlord considers necessary or reasonably desirable; to have access to
underfloor facilities and access panels to mechanical shafts and to check,
calibrate, adjust, and balance controls and other parts of the heating, air
conditioning, ventilating, and climate control systems.  The Landlord reserves
to itself the right to install, maintain, use, and repair pipes, ducts,
conduits, vents, wires, and other installations leading in, through, over, or
under the Premises and for this purpose, the Landlord may take all material
into and upon the Premises which is required therefor.  The Tenant shall not
unduly obstruct any pipes, conduits, or mechanical or other electrical
equipment so as to prevent reasonable access thereto.  The Landlord reserves
the right to use all exterior walls and roof area.  The Landlord shall exercise
its rights under this Section, to the extent possible in the circumstances, in
such a manner so as to minimize interference with the Tenant's use and
enjoyment of the Premises.

     4.2   Right to Show Premises.  The Landlord and its agents have the right 
to enter the Premises at all reasonable times during normal business hours and
upon reasonable notice to show them to prospective purchasers, lenders, or
anyone having a prospective interest in the Building, and during the last six
months of the Term (or the last six (6) months of any renewal term if this
Lease is renewed), to show them to prospective tenants in a manner which will
not unreasonably interfere with Tenant's business.

           ARTICLE 5.  MAINTENANCE, REPAIRS, AND ALTERATIONS.

     5.1   Maintenance and Repairs by the Landlord.  The Landlord covenants to 
keep the following in good repair: (i) the structure of the Building including
exterior walls and roofs; and (ii) the entrances, sidewalks, corridors, parking
areas and other facilities from time to time comprising the "Common Areas"
(subsequently defined).  The cost of such maintenance and repairs shall be
included in Operating Costs.  So long as the Landlord is acting in good faith,
the Landlord shall not be responsible for any damages caused to the Tenant by
reason of failure of any equipment or facilities serving the Building or delays
in the performance of any work for which the Landlord is responsible pursuant
to this Lease.  Notwithstanding any other provisions of this Lease, if any part
of the Building is damaged or destroyed or requires repair, replacement, or
alteration as a result of the act or omission of the Tenant, its employees,
agents, invitees, licensees, or contractors, the Landlord shall have the right
to perform same and the cost of such repairs, replacement or alterations shall
be paid by the Tenant to the Landlord upon demand.  In addition, if, in any
emergency, it shall become necessary to make promptly any repairs or
replacements required to be made by the Tenant, the Landlord may re-enter the
Premises and proceed forthwith to have the repairs or replacements made and pay
the costs thereof.  Upon demand, the Tenant shall reimburse the Landlord for
the cost of making the repairs.

     5.2 Maintenance and Repairs by the Tenant.  The Tenant shall, at its sole 
cost, repair and maintain the Premises including, but not limited to, base
building mechanical and electrical systems, all to a standard consistent with a
first class building, with the exception only of those repairs which are the
obligation of the Landlord pursuant to this Lease.  Without limiting the
generality of the foregoing, the Tenant is specifically required to maintain
and make repairs to (a) the portion of any pipes, lines, ducts, wires, or
conduits contained within the Premises and serving the Premises; (b) windows,
plate glass, doors, and any fixtures or appurtenances composed of glass; (c)
the Tenant's sign; (d) any heating or air conditioning equipment serving the
Premises ("HVAC") (which shall include, without limitation, a preventive
maintenance HVAC service contract, which service contract shall be entered into
between the Tenant and one of the Landlord's approved HVAC contractors; (Such
service contract shall include, without limitation, preventive HVAC maintenance
no less than quarterly.); (e) the Premises or the Building when repairs to the
same are necessitated by any act or omission of the Tenant, or the failure of
the Tenant to perform its obligations under this Lease; provided, however,
Landlord shall make repairs to the items described in "(a)-(e)" above during
the one (1) year period beginning with the Commencement Date, to the extent
that such repairs are made necessary solely by virtue of the Landlord's
improper installation of such items.  All repair and maintenance performed by
the Tenant in the Premises shall be performed by contractors or workmen
designated or approved by the Landlord, such approval not to be unreasonably
withheld by Landlord.  At the expiration or earlier termination of the Term,
the Tenant shall surrender the Premises to the Landlord in as good condition
and repair as the Tenant is required to maintain the Premises throughout the
Term. The Tenant shall also furnish, maintain, and replace a electric light
bulbs, tubes, and tube casings located within or serving the Premises and the
Tenant's signage, all at the Tenant's sole cost and expense.

      5.3 Approval of the Tenant's Alterations.  No alterations (including 
without limitation, repairs, replacements, additions, or modifications to the
Premises by the Tenant), other than minor or cosmetic alterations which are
interior and nonstructural, shall be made to the Premises without the
Landlord's written approval, which, as to exterior or structural alterations
may be withheld in Landlord's sole and absolute discretion.  Any alterations by
the Tenant shall be performed at the sole cost of the Tenant, by contractors
and workmen approved by the Landlord (which approval shall not be unreasonably
withheld), in a good and workmanlike manner, and in accordance with all
applicable laws and regulations.  Tenant shall be permitted to make repairs to
the Premises while Landlord is performing its work, provided that Landlord
shall determine in its reasonable judgment that such repairs by Tenant shall
not delay or interfere with Landlord's work, and subject to such reasonable
terms and conditions as Landlord may impose.

<PAGE>   11

     5.4   Removal of Improvements and Fixtures. All leasehold improvements 
(other than unattached, movable trade fixtures which can be removed without
damage to the Premises) shall at the expiration or earlier termination of this
Lease become the Landlord's property.  The Tenant may, during the Term, in the
usual course of its business, remove its trade fixtures, provided that the
Tenant is not in default under this Lease; and the Tenant shall, at the
expiration or earlier termination of the Term, at its sole cost, remove such of
the leasehold improvements (except for improvements installed by Landlord prior
to the commencement Date) and trade fixtures in the Premises as the Landlord
shall require to be removed and restore the Premises to the condition existing
prior to such removal.  The Tenant shall at its own expense repair any damage
caused to the Building by such removal.  If the Tenant does not remove its
trade fixtures at the expiration or earlier termination of the Term, the trade
fixtures shall, at the option of the Landlord, become the property of the
Landlord and may be removed from the Premises and sold or disposed of by the
Landlord in such manner as it deems advisable without any accounting to the
Tenant.

     5.5   Liens.  The Tenant shall promptly pay for all materials supplied and 
work done in respect of the Premises so as to ensure that no lien is recorded
against any portion of the Building or against the Landlord's or the Tenant's
interest therein.  If a lien is so recorded, the Tenant shall discharge it
promptly by payment or bonding.  If any such lien against the Building or
Landlord's interest therein is recorded and not discharged by the Tenant as
above required within fifteen (15) days following recording, the Landlord shall
have the right to remove such lien by bonding or payment and the cost thereof
shall be paid immediately from the Tenant to Landlord.  The Landlord and the
Tenant expressly agree and acknowledge that no interest of Landlord in the
Premises or the Building shall be subject to any lien for improvements made by
the Tenant in or for the Premises, and the Landlord shall not be liable for any
lien for any improvements made by the Tenant, such liability being expressly
prohibited by the terms of this Lease.  In accordance with applicable laws of
the State of Florida, the Landlord has filed in the public records of Dade
County, Florida, a public notice containing a true and correct copy of this
paragraph, and the Tenant hereby agrees to inform all contractors and
materialmen performing work in or for or supplying materials to the Premises of
the existence of said notice.

     5.6   Utilities.  The Tenant shall pay to the Landlord, or as the Landlord 
directs, all gas, water, and other utility charges applicable to the Premises
as separately metered or, if not so metered, as part of the Tenant's
proportionate share of Increased Operating Costs. Landlord shall separately
meter the Premises for electricity and the Tenant shall be solely responsible
for paying all charges.  The Tenant shall engage its own janitorial and garbage
removal services and shall pay the cost of janitorial and garbage removal
services for the Premises and the cost of heating, ventilating, and air
conditioning the Premises.

                 ARTICLE 6.  INSURANCE AND INDEMNITY.

     6.1   The Tenant's Insurance.  The Tenant shall, throughout the Term (and 
any other period when the Tenant is in possession of the Premises), maintain at
its sole cost the following insurance:

           6.1.1  All risks property insurance, naming the Tenant and the
Landlord as insured parties, containing a waiver of subrogation rights which
the Tenant's insurers may have against the Landlord and against those for whom
the Landlord is in law responsible including, without limitation, its
directors, officers, agents, and employees, and (except with respect to the
Tenant's chattels) incorporating a standard New York mortgagee endorsement
(without contribution).  Such insurance shall insure property of every kind
owned by the Tenant in an amount not less than the full replacement cost
thereof (new), with such cost to be adjusted no less than annually.

           6.1.2  Commercial general liability insurance.  Such policy shall 
contain inclusive limits per occurrence of not less than the amount specified
in the Lease Summary; provide for cross liability; and include the Landlord and
any mortgagee of the Landlord as additional insureds.


                                    8

<PAGE>   12

           6.1.3  Worker's compensation and employer's liability insurance in 
compliance with applicable legal requirements.

           6.1.4  Any other form of insurance which the Tenant or the Landlord, 
acting reasonably, requires from time to time in form, in amounts, and for 
risks against which a prudent tenant would insure.

           All policies referred to above shall: (a) be taken out with insurers 
licensed to do business in Florida and reasonably acceptable to the Landlord;
(b) be in a form reasonably satisfactory to the Landlord; (c) be
non-contributing with, and shall apply only as primary and not as excess to any
other insurance available to the Landlord or any mortgagee of the Landlord; (d)
contain an undertaking by the insurers to notify the Landlord by certified mail
not less than thirty (30) days prior to any material change, cancellation, or
termination; and (e) with respect to Subsection 6.2.2, contain replacement
cost, demolition cost, and increased cost of construction endorsements.
Certificates of insurance on the Landlord's standard form or, if required by a
mortgagee, copies of such insurance policies certified by an authorized officer
of the Tenant's insurer as being complete and current, shall be delivered to
the Landlord promptly upon request.  If the Tenant fails to take out or to keep
in force any insurance referred to in this Section 6.1, or should any such
insurance not be approved by either the Landlord or any mortgagee, then the
Landlord shall have the right, without assuming any obligation in connection
therewith, to effect such insurance at the sole cost of the Tenant and all
outlays by the Landlord shall be paid by the Tenant to the Landlord without
prejudice to any other rights or remedies of the Landlord under this Lease. 
The Tenant shall not keep or use on the Premises any article which may be
prohibited by any fire or casualty insurance policy in force from time to time
covering the Premises or the Building.

     6.2   Loss or Damage.  The Landlord shall not be liable for any death or 
injury arising from or out of any occurrence in, upon, at, or relating to the
Building or damage to property of the Tenant or of others located on the
Premises or elsewhere in the Building, nor shall it be responsible for any loss
of or damage to any property of the Tenant or others from any cause, unless
such death, injury, loss, or damage results from the gross negligence or
willful misconduct of the Landlord.  Without limiting the generality of the
foregoing, the Landlord shall not be liable for any injury or damage to persons
or property resulting from fire, explosion, falling plaster, falling ceiling
tile, falling fixtures, steam, gas, electricity, water, rain, flood, or leaks
from any part of the Premises or from the pipes, sprinklers, appliances,
plumbing works, roof, windows, or subsurface of any floor or ceiling of the
building or from the street or any other place or by dampness, or by any other
cause whatsoever.  The Tenant agrees to indemnify the Landlord and hold it
harmless from and against any and all loss (including loss of Minimum Rent and
Additional Rent payable in respect to the Premises), claims, actions, damages,
liability, and expense of any kind whatsoever (including reasonable attorneys'
fees and costs of any kind), UNLESS CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF THE LANDLORD OR ITS AGENTS, arising from any occurrence in, upon,
or at the Premises, or the occupancy, use, or improvement by the Tenant or its
agents or invitees of the Premises or any part thereof, or occasioned wholly or
in part by any act or omission of the Tenant, its agents, employees, and
invitees or by anyone permitted to be on the Premises by the Tenant.

     6.3   The Landlord's Insurance.  To the extent reasonably available, the 
Landlord shall, throughout the Term carry: (i) "all risks" insurance on the
Building and the machinery and equipment contained therein or servicing the
Building and owned by the Landlord (excluding any property with respect to
which the Tenant and other tenants are obliged to insure pursuant to Section
6.1 or similar sections of their respective leases); (ii) public liability and
property damage insurance with respect to the Landlord's operations in the
Building; and (iii) such other forms of insurance as the Landlord or its
mortgagee reasonably considers advisable, all in such amounts and with such
deductibles as the Landlord in its sole and absolute discretion deems
advisable.

<PAGE>   13

                     ARTICLE 7.  DAMAGE AND DESTRUCTION.

     7.1   Damage to Premises.  If the Premises are partially destroyed due to 
fire or other casualty, the Landlord shall diligently repair the Premises, to
the extent of its obligations under section 5.1, and Minimum Rent shall abate
proportionately to the portion of the Premises, if any, rendered untenantable
from the date of destruction or damage until the Landlord's repairs have been
substantially completed. If the Premises are totally destroyed due to fire or
other casualty, the Landlord shall diligently repair the Premises to the extent
only of its obligations pursuant to section 5.1, and Minimum Rent shall abate
entirely from the date of destruction or damage to such date which is the
earlier of (i) the date tenantable, or (ii) thirty (30) days after Landlord's
repairs have been substantially completed.  Upon being notified by the Landlord
that the Landlord's repairs have been substantially completed, the Tenant shall
diligently perform all other work required to fully restore the Premises for
use in the Tenant's business, in every case at the Tenant's cost and without
any contribution to such cost by the Landlord, whether or not the Landlord has
at any time made any contribution to the cost of supply, installation, or
construction of leasehold improvements in the Premises.  Tenant agrees that
during any period of reconstruction or repair of the Premises, it will continue
the operation of its business within the Premises to the extent practicable. 
If all or any part of the Premises shall be damaged by fire or other casualty
and the fire or other casualty is caused by the fault of neglect of Tenant or
Tenant's agents, guest, or invitees, rent and all other charges shall not
abate. 

     7.2   Termination for Damage.  Notwithstanding section 7.1, if damage or 
destruction which has occurred to the Premises or the Building is such that in
the reasonable opinion of the Landlord such reconstruction or repair cannot be
completed (as evidenced by a Certificate of Occupancy) within one hundred
eighty (180) days of the happening of the damage or destruction, the Landlord
may, at its option, terminate this Lease on notice to the Tenant given within
thirty (30) days after such damage or destruction and the Tenant shall deliver
vacant possession of the Premises in accordance with the terms of this Lease as
soon as possible, but in no event more than thirty (30) days after such notice;
provided, however, during the last year of the Lease or any renewal period, the
Landlord shall have the right to terminate this Lease in the event of any
casualty to the Premises constituting more than thirty (30%) percent of the
prior value thereof.


            ARTICLE 8.  ASSIGNMENT, SUBLEASES, AND TRANSFERS.

      8.1  Transfer by the Tenant.

           8.1.1  The Tenant shall not enter into, consent to, or permit any 
Transfer, as hereinafter defined, without the prior written consent of the
Landlord in each instance, which consent may be granted or withheld in the
Landlord's sole and reasonable discretion.  For purposes of this Lease,
"Transfer" means an assignment of this Lease in whole or in part; a sublease of
all or any part of the Premises; any transaction whereby the rights of the
Tenant under this Lease or to the Premises are transferred to another; any
mortgage or encumbrance of this Lease or the Premises or any part thereof or
other arrangement under which either this Lease or the Premises become security
for any indebtedness or other obligations (all whether by operation of law or
otherwise); and if the Tenant is a corporation or a partnership, the transfer
of a controlling interest in the stock of the corporation or partnership
interests, as applicable.  Any transfer done without the Landlord's prior
written consent (unless such consent is not required under the terms of this
Lease) shall, at the Landlord's election be void.


           8.1.2  Notwithstanding the foregoing, Tenant may assign this Lease 
or sublease the Premises (in whole, but not in part) to a "Controlled Entity"
(subsequently defined) which is engaged exclusively in the same business as
Tenant, provided that (a) Tenant provides Landlord with ten days' prior written
notice of such assignment or sublease, (b) Tenant acknowledges, in form and
substance reasonably satisfactory to Landlord, that it remains jointly and
severally liable for all obligations of Tenant under this Lease, and (c) Tenant
provides or causes to be provided all such documents and information as
Landlord may reasonably request, including, without limitation, a written
assumption by such assignee or sublessee of all obligations under this Lease. 
For purposes of this Section 8.1.2 Controlled Entity means any



                                   10

<PAGE>   14

corporation, partnership, trust or other entity, in which all of the voting and
equity securities are owned and controlled by (a) Ross White Enterprises, Inc.
or (b) the shareholders owning and controlling a majority of the equity and
voting securities of Ross White Enterprises, Inc.

           8.1.3  If there is a permitted Transfer (or any other Transfer), the
Landlord may collect rent or other payments from the transferee and apply the
net amount collected to the rent or other payments required to be paid pursuant
to this Lease but no acceptance by the Landlord of any payments by a transferee
shall be deemed a waiver of any provisions hereof regarding the Tenant. 
Notwithstanding any Transfer, the Tenant shall not be released from any of its
obligations under this Lease.  The Landlord's consent to any Transfer shall be
subject to the further condition that if the Minimum Rent and Additional Rent
pursuant to such Transfer exceeds the Minimum Rent and Additional Rent payable
under this Lease, one-half of the amount of such excess (after deduction of the
Tenant's reasonable legal fees, reasonable brokerage fees and other reasonable
costs of Tenant in connection with such Transfer) shall be paid to the
Landlord, upon receipt by Tenant.  If, pursuant to a Transfer, the Tenant
receives from the transferee, either directly or indirectly, any consideration
other than Minimum Rent and Additional Rent for such Transfer, either in the
form of cash, goods, or services, the Tenant shall, upon receipt thereof,
similarly pay to the Landlord an amount equivalent to one-half of such
consideration (after deducting Tenant's reasonable legal fees, reasonable
brokerage fees and other reasonable costs).

     8.2   Notice of Proposed Transfer.  If the Tenant shall at any time or 
times during the term of this Lease desire to Transfer or assign this Lease or
to sublease all or part of the Premises, the Tenant shall give written notice
to the Landlord requesting the Landlord's prior written consent to the proposed
transfer, assignment or sublease and shall submit a $1,000 nonrefundable
processing fee.  Such notice shall be accompanied by (a) a statement setting
forth the name and address of the proposed assignee or subtenant, the nature of
its business, and its proposed use of the Premises; (b) current financial
information with respect to the proposed transferee, assignee or subtenant,
including, without limitation, its most recent financial report and audited
financial reports; (c) a true and complete copy of the executed transfer
document, assignment or sublease, conditioned only upon approval of the
Landlord; and (e) such other information as the Landlord may request in its
sole and absolute discretion.

     8.3   Consideration with Respect to a Transfer.  Without in any way 
obligating the Landlord to consent to any assignment, sublease or other
Transfer, the Landlord's consent may be predicated, among other things, on the
Landlord's evaluation of following criteria:

           8.3.1  the consistency of the proposed use, with the use permitted 
under this Lease;

           8.3.2  the nature of the proposed use in relation to tenants and 
owners, and proposed tenants and owners and development plans, of the Beacon 
Centre;

           8.3.3  the potential liability of any kind to Landlord with respect 
to the Transfer, the proposed transferee, assignee, or sublessee or the use 
contemplated by such transferee, assignee or sublessee;

           8.3.4  the use, storage, disposition or handling, or potential use, 
storage, disposition or handling, if any, of hazardous materials or waste;

           8.3.5  the assumption by the assignee or sublessee of all 
obligations under this Lease;

           8.3.6  the creditworthiness of the proposed assignee, sublessee, or

other tenants and owners, or potential tenants and owners of the Beacon Centre

<PAGE>   15

           8.3.8  the proposed sublease, assignment or Transfer or the use
thereby does not violate any applicable law, regulation or order.

     8.4   Right of Landlord to Terminate. In addition to its other rights 
under this Lease, and without in any way limiting such rights, upon receipt of
any notice of a Transfer, or upon any such Transfer without the Landlord's
consent, the Landlord may terminate this Lease. The Landlord may exercise its
right to terminate this Lease upon sixty (60) days prior written notice after
receipt of the notice required by Section 8.2 or at any time after a Transfer
which is made without such notice.  The foregoing provisions of this Section
8.4 do not apply to any Transfer for which this Lease provides that no consent
of the Landlord is necessary.

     8.5   Assignment by the Landlord.  The Landlord shall have the 
unrestricted right to sell, lease, convey, or otherwise dispose of the Building
or any part thereof and this Lease or any interest of the Landlord in this
Lease.  To the extent that the purchaser or assignee from the Landlord assumes
the obligations of the Landlord under this Lease, the Landlord shall thereupon
and without further agreement be released of all further liability under this
Lease.  If the Landlord sells its interest in the Premises, it shall deliver
the security deposit to the purchaser and the Landlord will thereupon be
released from any further liability with respect to the security deposit or its
return to the Tenant and the purchaser shall become directly responsible to the
Tenant.

                         ARTICLE 9.  DEFAULT.

     9.1   Defaults.  A default by the Tenant shall be deemed to have occurred 
hereunder, if and whenever:

           9.1.1  any Minimum Rent, Additional Rent (including, without
limitation, the Tenant's proportionate share of Increased Operating Costs) is
not paid within ten (10) days of the Landlord delivering notice to Tenant of
such default; provided, however, that the Landlord shall not be required to
provide such notice more than three (3) times during any calendar year;

           9.1.2  a Transfer shall occur, except as permitted under this Lease;

           9.1.3  the Tenant has breached any of its obligations under this 
Lease (other than the payment of Rent) and the Tenant fails to remedy such
breach within twenty (20) days (or such shorter period as may be provided in
this Lease) after receiving notice of such breach (except that no notice shall
be required in the case of a breach knowingly and intentionally committed by
Tenant);

           9.1.4  the Tenant becomes bankrupt or insolvent, or generally fails 
to pay its obligations when due, or the Tenant takes the benefit of any
reorganization or composition proceeding, makes an assignment for the benefit
of creditors, takes the benefit of (as to itself) of any insolvency laws, or a
petition in bankruptcy or insolvency proceeding is initiated against the Tenant
or its property and the Tenant shall acquiesce in such proceedings or fail to
obtain their dismissal within thirty (30) days of the filing thereof;

           9.1.5  the Premises shall be abandoned or deserted by the Tenant;

           9.1.6  any of the Landlord's policies of insurance with respect to 
the Building are cancelled or adversely changed as a result of the Tenant's use 
or occupancy of the Premises; or

           9.1.7  the business operated by the Tenant in the Premises shall be 
closed by governmental or court order for any reason.

     9.2   Remedies.  In the event of any default hereunder by the Tenant, then 
without prejudice to any other rights which it has pursuant to this Lease or at
law or in equity, the Landlord shall have the following rights and remedies,
which are cumulative and not alternative:


                                   12

<PAGE>   16

           9.2.1  The Landlord may cancel this Lease by notice to the Tenant 
and retake possession of the Premises for the Landlord's account.  The Tenant
shall then quit and surrender the Premises to the Landlord.  The Tenant's
liability under all of the provisions of this Lease shall continue
notwithstanding any expiration and surrender, or any re-entry, repossession, or
disposition hereunder.

           9.2.2  The Landlord may enter the Premises as agent of the Tenant to 
take possession of any property of the Tenant on the Premises to store such
property at the expense and risk of the Tenant or to sell or otherwise dispose
of such property in such manner as the Landlord may see fit without notice to
the Tenant.  Re-entry and removal may be effectuated by summary dispossession
proceedings, by any suitable action or proceeding, or otherwise.  The Landlord
shall not be liable in any way in connection with its actions pursuant to this
section, to the extent that its actions are in accordance with law.

           9.2.3  If this Lease is cancelled under Subsection 9.2.1 above, the 
Tenant shall remain liable (in addition to accrued liabilities) to the extent
legally permissible for all Rent and all of the charges the Tenant would have
been required to pay until the date this Lease would have expired had such
cancellation not occurred.  The Tenant's liability for Rent shall continue
notwithstanding re-entry or repossession of the Premises by the Landlord.  In
addition to the foregoing, the Tenant shall pay to Landlord all reasonable
attorneys fees and costs of any kind with respect to any successful lawsuit or
action instituted by the Landlord to enforce the provisions of this Lease or in
connection with any default by the Tenant hereunder.

           9.2.4  The Landlord may relet all or any part of the Premises for 
all or any part of the unexpired portion of the Term of this Lease or for any
longer period, and may accept any rent then attainable; grant any concessions
of Rent, and agree to paint or make any special repairs, alterations, and
decorations for any new Tenant as it may deem advisable in its sole and
absolute discretion.  The Landlord shall be under no obligation to relet or to
attempt to relet the Premises.

           9.2.5  If this Lease is canceled in accordance with Subsection 9.2.1 
above, and if the Landlord so elects, the Rent hereunder shall be accelerated
and the Tenant shall pay the Landlord damages in the amount of any and all sums
which would have been due for the remainder of the Term.

           9.2.6  The Landlord may remedy or attempt to remedy any default of 
the Tenant under this Lease for the account of the Tenant and to enter upon the
Premises for such purposes.  No notice of the Landlord's intention to perform
such covenants need be given the Tenant unless expressly required by this
Lease.  The Landlord shall not be liable to the Tenant for any loss or damage
caused by acts of the Landlord in remedying or attempting to remedy such
default and the Tenant shall pay to the Landlord all expenses of any kind
(including, without limitation, reasonable attorneys' fees and costs of any
kind) incurred by the Landlord in connection with remedying or attempting to
remedy such default.  Any expenses incurred by the Landlord shall accrue
interest from the date of payment by the Landlord until repaired by the Tenant
at the highest rate permitted by law.

     9.3   Costs.  The Tenant shall pay to the Landlord on demand all costs of 
any kind incurred by the Landlord, including, without limitation reasonable
attorneys' fees and costs of any kind, incurred by the Landlord in enforcing
any of the obligations of the Tenant under this Lease or in connection with any
default by Tenant under this Lease.  In addition, upon any default by the
Tenant, the Tenant shall be also liable to the Landlord for the expenses to
which the Landlord may be put in re-entering the Premises; repossessing the
Premises; painting, altering, or dividing the Premises; combining the Premises
with an adjacent space for any new tenant; putting the Premises in proper
repair; protecting and preserving the Premises by placing watchmen and
caretakers therein; reletting the Premises (including reasonable attorneys'
fees and disbursements, marshall's fees, and brokerage fees, in so doing); and
any other expenses reasonably incurred by the Landlord.

<PAGE>   17

     9.4   Additional Remedies; Waiver.  The rights and remedies of the 
Landlord set forth herein shall be in addition to any other right and remedy
now and hereinafter provided by law. All rights and remedies shall be
cumulative and non-exclusive of each other.  No delay or omission by the
Landlord in exercising a right or remedy shall exhaust or impair the same or
constitute a waiver of, or acquiescence to, a default.

     9.5   Default by the Landlord.  In the event of any default by the
Landlord, except as expressly provided otherwise in this Lease, Tenant's
non-exclusive remedy shall be an action for damages, but prior to any such
action the Tenant will give the Landlord written notice specifying such default
with particularity, and the Landlord shall have a period of thirty (30) days
following the date of such notice in which to commence the appropriate cure of
such default.  Notwithstanding the foregoing sentence, the Tenant shall not be
entitled to the remedy of specific performance or any other equitable remedy. 
Unless and until the Landlord fails to commence and diligently pursue the
appropriate cure of such default after such notice or complete same within a
reasonable period of time, the Tenant shall not have any remedy or cause of
action by reason thereof.  If the Landlord, or any successor or assign, fails
to perform any covenant, term or condition of this Lease upon the Landlord's
part to be performed and as a consequence of such default the Tenant recovers a
money judgment against the Landlord, such judgment shall be satisfied only out
of the proceeds of sale received upon execution of such judgment and levy
thereon against the right, title and interest of Landlord in the Demised
Premises as the same may then be encumbered and neither the Landlord nor, if
the Landlord be a partnership, any of the partners comprising the Landlord,
will be liable for any deficiency.  It is understood that in no event shall the
Tenant have the right to levy execution against any property of the Landlord
other than its interest in the Premises as hereinbefore expressly provided.  In
the event of the sale or other transfer of the Landlord's right, title and
interest in the Premises, the Landlord will be released thereby from all
liability and obligations under this Lease.

           ARTICLE 10.  ESTOPPEL CERTIFICATE; SUBORDINATION.

     10.1  Estoppel Certificate.  Within ten (10) days after written request by 
the Landlord, the Tenant shall deliver in a form supplied by the Landlord, an
estoppel certificate to the Landlord as to the status of this Lease, including
whether this Lease is unmodified and in full force and effect (or, if there
have been modifications, that this Lease is in full force and effect as
modified and identifying the modification agreements); the amount of Minimum
Rent and Additional Rent then being paid and the dates to which same have been
paid; whether or not there is any existing or alleged default by either party
with respect to which a notice of default has been served, or any facts exist
which, with the passing of time or giving of notice, would constitute a
default, and if there is any such default or facts, specifying the nature and
extent thereof; and any other matters pertaining to this Lease as to which the
Landlord shall request such certificate.  The Landlord, and any prospective
purchaser, lender, or ground lessor shall have the right to rely on such
certificate.

     10.2  Subordination; Attornment.  This Lease and all rights of the Tenant 
shall be subject and subordinate to any and all mortgages, security agreements,
or like instruments resulting from any financing, refinancing, or collateral
financing (including renewals or extensions thereof), and to any and all ground
leases, made or arranged by the Landlord of its interests in all or any part of
the Building), from time to time in existence against the Building, whether now
existing or hereafter created.  Such subordination shall not require any
further instrument to evidence such subordination.  However, on request, the
Tenant shall further evidence its agreement to subordinate this Lease and its
rights under this Lease to any and all documents and to all advances made under
such documents.  The form of such subordination shall be made as required by
the Landlord, its lender, or ground lessor.  The Tenant shall, if requested by
such mortgagee, owner, or purchaser, or by any person succeeding to the
interest of such mortgagee, owner, or purchaser, or by any person succeeding to
the interest of such mortgagee, owner, or purchaser, as the result of the
enforcement of the remedies provided by law or the applicable security
instrument held by such mortgagee, owner, or purchaser, automatically become
the tenant of any such mortgagee, owner, purchaser, or successor-in-interest,
without any change in the terms or other provisions of this Lease; provided,
however, that said mortgagee, owner, purchaser, or successor shall not be bound
by (a) any payment of


                                   14

<PAGE>   18

rent or additional rent for more than one month in advance, or (b) any security
deposit or the like not actually received by such mortgagee, owner, or
purchaser, or successor, or (c) any amendment or modification in this Lease
made without the consent of such mortgagee, owner, purchaser, or successor
thereto (to the extent that such mortgagee, owner, purchaser or
successor-in-interest thereto had an interest of any kind in the Premises at
the time of such amendment or modification), or (d) any construction
obligation, free rent, or other concession or monetary allowance, or (e) any
set-off, counterclaim, or the like otherwise available against the Landlord, or
(f) any act or omission of any prior landlord (including the Landlord).  Upon
request by said mortgagee, owner, or purchaser, or successor, the Tenant shall
execute and deliver an instrument or instruments confirming its attornment.
Notwithstanding the foregoing, any such subordination shall be conditioned upon
the Landlord obtaining a nondisturbance agreement in favor of Tenant from all
mortgagees having mortgages encumbering the Premises.  Further, amendments and
modifications referred to in "(c)" above shall be subject to reasonable
negotiation by the Tenant and the Landlord's lenders and ground lessors, if
any. 

            ARTICLE 11.  CONTROL OF BUILDING BY THE LANDLORD.

     11.1  Use and Maintenance of Common Areas.  The Tenant and those doing 
business with the Tenant for purposes associated with the Tenant's business on
the Premises, shall have a non-exclusive license to use the Common Areas for
their intended purposes during normal business hours in common with others
entitled thereto and subject to any rules and regulations imposed by the
Landlord.  The Landlord shall keep the Common Areas in good repair and
condition and shall clean the Common Areas when necessary.  Subject to all of
the terms, provisions, covenants, and conditions contained herein, the Tenant
shall have the right to use its proportionate share of the number of parking
spaces indicated in the Lease Summary in the parking lot which the Landlord
shall provide for the use of tenants of the Building.  The Landlord shall not
be liable for any damage to automobiles of any nature whatsoever to, or any
theft of, automobiles or other vehicles or the contents thereof, while in or
about the parking lots.  The Landlord shall not have any responsibility for the
use of the parking lots by unauthorized individuals.  The Tenant acknowledges
that its non-exclusive right to use any parking facilities forming part of the
Building may be subject to such rules and regulations as reasonably imposed by
the Landlord from time to time.  The Tenant acknowledges that all Common Areas
shall at all times be under the exclusive control and management of the
Landlord.  For purposes of this Lease, "Common Areas" shall mean those areas,
facilities, utilities, improvements, equipment, and installations of the
Building which serve or are for the benefit of the tenants of more than one
component of the Building and which are not designated or intended by the
Landlord to be leased, from time to time, or which are provided or designated
from time to time by the Landlord for the benefit or use of all tenants in the
Building, their employees, customers, and invitees, in common with others
entitled to the use or benefit of same.

     11.2  Alterations by the Landlord.  The Landlord may (a) alter, add to, 
subtract from, construct improvements on, re-arrange, and construct additional
facilities in, adjoining, or proximate to the Building; (b) relocate the
facilities and improvements in or comprising the Building or erected on the
land; (c) do such things on or in the Building as required to comply with any
laws, by-laws, regulations, orders, or directives affecting the land or any
part of the Building; and (d) do such other things on or in the Building as the
Landlord, in the use of good business judgment determines to be advisable,
provided that notwithstanding anything contained in this Section 11.2, access
to the Premises shall be available at all times.  The Landlord shall not be in
breach of its covenants for quiet enjoyment or liable for any loss, costs, or
damages, whether direct or indirect, incurred by the Tenant due to any of the
foregoing.

     11.3  Covenants, Conditions, and Restrictions.  The Tenant hereby
acknowledges and agrees that the Building of which the Premises is a part, and
the Tenant's occupancy thereof, is subject to Declarations of Covenants,
Conditions, and Restrictions for Beacon Centre (the "Declarations"), which
Declarations have been recorded among the Public Records of Dade County,
Florida.  Copies of the Declarations are located at the Landlord's management
office and may be reviewed by the Tenant during the Landlord's normal business
hours.  The Tenant hereby acknowledges the existence of such Declarations and
agrees to be bound by the terms thereof (and any amendments or modifications
thereto). The Tenant hereby agrees to reimburse



                                   15

<PAGE>   19

the Landlord, within fifteen (15) days after demand therefor, for the
proportionate share of Common Expenses and Common Element Expenses attributable
to the Premises (as described in the Declarations) to the extent that such
amounts in any calendar year exceed the total amount of such items during the
Base Year.  It is the Landlord's intention not to double charge the Tenant for
any expenses pursuant to Section 2.3 of this Lease and the Declaration(s).  The
expenses solely relating to the Building are intended to be charged pursuant to
Section 2.3 of this Lease.  Those expenses that are incurred by the Landlord on
a park-wide basis (including, without limitation, park-wide security and
landscaping of the perimeter berm) are passed-through pursuant to the
Declarations.

                       ARTICLE 12.  CONDEMNATION.

     12.1  Total or Partial Taking.  If the whole of the Premises, or such 
portion thereof as will make the Premises unusable for the purposes leased
hereunder, shall be taken by any public authority under the power of eminent
domain or sold to public authority under threat or in lieu of such taking, the
Term shall cease as of the day possession or title shall be taken by such
public authority, whichever is earlier ("Taking Date"), whereupon the Rent and
all other charges shall be paid up to the Taking Date with a proportionate
refund by the Landlord of any Rent and all other charges paid for a period
subsequent to the Taking Date.  If less than the whole of the Premises, or less
than such portion thereof as will make the Premises unusable for the purposes
leased hereunder, the Term shall cease only as to the part so taken as of the
Taking Date, and the Tenant shall pay Rent and other charges up to the Taking
Date, with appropriate credit by the Landlord (toward the next installment of
Rent due from the Tenant) of any Rent or charges paid for a period subsequent
to the Taking Date.  Minimum Rent and other charges payable to the Landlord
shall be reduced in proportion to the amount of the Premises taken.

     12.2  Taking for Temporary Use.  If there is a taking of the Premises for 
temporary use, this Lease shall continue in full force and effect, and the
Tenant shall continue to comply with the Tenant's obligations under this Lease,
except to the extent compliance shall be rendered impossible or impracticable
by reason of the taking.  Minimum Rent and other charges payable to the
Landlord shall be reduced in proportion to the amount of the Premises taken for
the period of such temporary use.

     12.3  Award.  All compensation awarded or paid upon a total or partial 
taking of the Premises or Building including the value of the leasehold estate
created hereby shall belong to and be the property of the Landlord without any
participation by the Tenant; the Tenant shall have no claim to any such award
based on the Tenant's leasehold interest.  However, nothing contained herein
shall be construed to preclude the Tenant, at its cost, from independently
prosecuting any claim directly against the condemning authority in such
condemnation proceeding for damage to, or cost of removal of, stock, trade
fixtures, furniture, and other personal property belonging to the Tenant;
provided, however, that no such claim shall diminish or otherwise adversely
affect the Landlord's award or the award of any mortgages.

                    ARTICLE 13.  GENERAL PROVISIONS

     13.1  Delay.  Except as expressly provided in this Lease (including, 
without limitation, Section 1.2), whenever the Landlord is delayed in the
fulfillment of any obligation under this Lease, by an unavoidable occurrence
which is not the fault of the Landlord delayed in performing such obligation,
then the time for fulfillment of such obligation shall be extended during the
period in which such circumstances operate to delay the fulfillment of such
obligation.

     13.2  Holding Over.  If the Tenant remains in possession of the Premises 
after the end of the Term without having executed and delivered a new lease or
an agreement extending the Term, there shall be no tacit renewal of this Lease
or the Term, and the Tenant shall be deemed to be occupying the Premises as a
Tenant from month to month at a monthly Minimum Rent payable in advance on the
first day of each month equal to one hundred fifty percent (150%) of the
monthly amount of Minimum Rent payable during the last month of the Term, and
otherwise upon the same terms as are set forth in this Lease, so far as they
are applicable to a monthly tenancy.



                                   16

<PAGE>   20

     13.3  Waiver: Partial Invalidity.  If either the Landlord or the Tenant 
excuses or condones any default by the other of any obligation under this
Lease, this shall not be a waiver of such obligation in respect of any
continuing or subsequent default and no such waiver shall be implied.  All of
the provisions of this Lease are to be construed as covenants even though not
expressed as such.  If any such provision is held or rendered illegal or
unenforceable it shall be considered separate and severable from this Lease and
the remaining provisions of this Lease shall remain in force and bind the
parties as though the illegal or unenforceable provision had never been
included in this Lease.

     13.4  Recording.  Neither the Tenant nor anyone claiming under the Tenant 
shall record this Lease or any memorandum hereof in any public records without
the prior written consent of the Landlord.

     13.5  Notices.  Any notice, consent, or other instrument required or 
permitted to be given under this Lease shall be in writing and shall be
delivered by certified mail, return receipt requested, or overnight express
mail courier, postage prepaid, addressed (i) if to the Landlord, at the address
set forth on the Lease Summary; and (ii) if to the Tenant, at the Premises or,
prior to the Tenant's occupancy of the Premises, at the address set forth on
the Lease Summary.  Any such notice or other instruments shall be deemed to
have been given and received on the day upon which personal delivery is made
or, if mailed, then forty-eight (48) hours following the date of mailing. 
Either party may give notice to the other of any change of address and after
the giving of such notice, the address therein specified is deemed to be the
address of such party for the giving of notices.  If postal service is
interrupted or substantially delayed, all notices or other instruments shall be
delivered in person or by overnight express mail courier.

     13.6  Successors: Joint and Several Liability.  The rights and 
liabilities created by this Lease extend to and bind the successors and assigns
of the Landlord and the heirs, executors, administrators, and permitted
successors and assigns of the Tenant.  No rights, however, shall inure to the
benefit of any transferee unless such Transfer complies with the provisions of
Article 8. If there is at any time more than one Tenant or more than one person
constituting the Tenant, their covenants shall be considered to be joint and
several and shall apply to each and every one of them.

     13.7  Captions and Section Numbers.  The captions, section numbers, 
article numbers, and table of contents appearing in this Lease are inserted
only as a matter of convenience and in no way affect the substance of this
Lease.

     13.8  Extended Meanings.  The words "hereof," "hereto," "hereunder," and 
similar expressions used in this Lease related to the whole of this Lease and
not only to the provisions in which such expressions appear.  This Lease shall
be read with all changes in number and gender as may be appropriate or required
by the context. Any reference to the Tenant includes, when the context allows,
the employees, agents, invites, and licensees of the Tenant and all others over
whom the Tenant might reasonably be expected to exercise control. This Lease
has been fully reviewed and negotiated by each party and their counsel and
shall not be more strictly construed against either party.

     13.9  Entire Agreement; Governing Law; Time.  This Lease and the Exhibits 
and Riders, if any, attached hereto are incorporated herein and set forth the
entire agreement between the Landlord and the Tenant concerning the Premises
and there are no other agreements or understandings between them.  This Lease
and its Exhibits and Riders may not be modified except by agreement in writing
executed by the Landlord and the Tenant.  This Lease shall be construed in
accordance with and governed by the laws of the State of Florida, without
application of conflict of laws principles.  Time is of the essence of this
Lease.

     13.10 No Partnership.  Nothing in this Lease creates any relationship 
between the parties other than that of lessor and lessee and nothing in this
Lease constitutes the Landlord a partner of the Tenant or a joint venture or
member of a common enterprise with the Tenant.

     13.11 Quiet Enjoyment.  If the Tenant pays Rent and other charges when due 
and 

                                   17

<PAGE>   21

otherwise fully observes and performs all of its obligations under this
Lease, the Tenant shall be entitled to peaceful and quiet enjoyment of the
Premises for the Term without interruption or interference by the Landlord or
any person claiming through the Landlord.

     13.12 Brokerage.  The Landlord and the Tenant each represent and warrant 
one to the other that except as set forth in the Lease Summary (i.e. Codina
Klein Realty, Inc. and ANF Real Estate Group, Inc.), neither of them has
employed any broker in connection with the negotiations of the terms of this
Lease or the execution thereof.  The Landlord and the Tenant hereby agree to
indemnify and to hold each other harmless against any loss, expense, or
liability with respect to any claims for commissions or brokerage fees arising
from or out of any breach of the foregoing representation and warranty.  The
Landlord recognizes the broker(s) specified in the Lease Summary as the sole
broker(s) with whom the Landlord has dealt in this transaction and agrees to
pay any commissions determined to be due said broker(s).  The Tenant
acknowledges that Bush Klein Realty, Inc. represents solely the Landlord with
respect to this Lease.

     13.13 ACCORD AND SATISFACTION.  No payment by the Tenant, or receipt by 
the Landlord of a lesser amount than the Rent required under this Lease will be
deemed to be other than on account of the earliest stipulated Rent nor shall
any endorsement or statement on any check or any letter accompanying any check
or payment of Rent be deemed an accord and satisfaction, and the Landlord may
accept such check or payment without prejudice to the Landlord's right to
recover the balance of such Rent or pursue any other remedy provided for in
this Lease or available at law or in equity.

     13.14 TRIAL BY JURY.  THE LANDLORD AND THE TENANT EACH HEREBY KNOWINGLY, 
VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT THAT IT OR THEY MANY HAVE TO A
TRIAL BY JURY WITH RESPECT TO ANY LITIGATION OR CONTROVERSY BASED UPON THIS
LEASE, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS LEASE OR ANY
TRANSACTION, MATTER, COURSE OF CONDUCT, STATEMENTS OR ACTIONS OF ANY PARTY TO
THIS LEASE.  EACH OF THE PARTIES ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL
INDUCEMENT FOR THE PARTIES ENTERING INTO THIS LEASE.

     13.15 Counterparts.  This Lease may be executed in a number of identical 
counterparts, each of which for all purposes is deemed an original, and all of
which collectively constitute one agreement, but in making proof of this Lease,
it shall not be necessary to produce or account for more than one such
counterpart.

     13.16 Execution by the Landlord.  The submission of this Lease to the 
Tenant shall not constitute an offer by the Landlord, and until such time as
this Lease is fully executed and delivered by the Landlord and the Tenant, this
Lease may be withdrawn by the Landlord.

     13.17. NOTICE REQUIRED BY CHAPTER 88-285, LAWS OF FLORIDA.

     Chapter 88-285, Laws of Florida, requires the following notice to be 
provided with respect to the contract for sale and purchase of any building, or
a rental agreement for any building:

     "RADON GAS: Radon is a naturally occurring radioactive gas that, when it 
has accumulated in a building in sufficient quantities, may present health
risks to persons who are exposed to it over time. Levels of radon that exceed
federal and state guidelines have been found in buildings in Florida. 
Additional information regarding radon and radon testing may be obtained form
your county public health unit."

portion of the Premises, except as set forth in (i) - (ix) above, which are
requested by Tenant to the warehouse portion of the Premises shall be borne by
Tenant.

         (b) Within fifteen (15) days following receipt of the final approved
plans and specifications for the Premises, Landlord shall have its contractor(s)
prepare an estimated budget (the "Construction Budget") of the cost of the
Tenant Improvements, and shall submit same to Tenant. ANF shall also be
permitted to prepare a Construction Budget and at Tenant's election, serve as
the contractor for the Tenant Improvements, subject to reasonable and ordinary
criteria and qualifications established by Landlord. The Construction Budget
shall be in reasonable detail and shall reflect a unit cost for all improvements
which is reasonable in amount, given the then current market conditions
pertinent to labor and material costs for such construction. The cost of the
Tenant Improvements, as set forth in the construction Budget, shall also include
the cost of all utilities, air conditioning, security, and other services
provided during construction. The Construction Budget shall be used as a basis
for calculating Tenant's Costs, as hereinafter defined, if any. Following final
completion of the Tenant Improvements, Landlord shall provide Tenant with a
statement of actual costs thereof, including the cost of any approved change
orders. Landlord's general contractor shall be licensed and insured in the State
of Florida and Dade County.

         (c) Upon Substantial Completion of the Premises, Tenant, at its
expense, shall install its furniture, trade fixtures, and equipment so that
Tenant can occupy the Premises for the use and purposes intended. Tenant may
begin to install such items prior to Substantial Completion; provided, however,
that no such pre-Substantial Completion installation shall in any way delay or
interfere with Landlord's work pursuant to this Work Letter and Tenant shall
arrange a meeting to coordinate with Landlord prior to any such pre-Substantial
Completion installation.

         (d) Tenant shall be responsible for any delay (including associated
costs) in Substantial Completion resulting from any of the following causes:

                  (i) Tenant's failure to timely approve (or submit to Landlord
         any proposed modifications or additions to) the plans and
         specifications, unless such failure is due to causes beyond Tenant's
         control; or

                  (ii) Tenant's failure to pay any portion of Tenant's Costs, as
         hereinafter defined, when due; or

                  (iii) Tenant's specification of special materials or finishes,
         or special installations, which special items cannot be delivered or
         completed within Landlord's construction schedule (subject to
         Landlord's obligation to give Tenant prior notice of same at the time
         of such specification); or

                  (iv) any change in the plans and specifications caused by
         Tenant once finally approved and accepted by Landlord, even though
         Landlord may approve such change (Landlord agrees to estimate the delay
         to be caused by a change order, provided Tenant expressly requests such
         estimate at the time it requests a change order); or

         If any delay caused by Tenant results in or contributes to a delay in
Substantial Completion, then Substantial Completion shall be deemed to have
occurred as of the date Landlord would have otherwise achieved Substantial
Completion, but for Tenant's delay. Landlord will specify in writing to Tenant
the Tenant delays(s) which resulted in or contributed to a delay in Substantial
Completion.

         (e) Landlord will provide Tenant with an allowance (the "Tenant
Improvement Allowance") as a credit against the cost of the improvements to the
office portion of the Premises and as against the fees and costs incurred with
respect to preparation of the plans and specifications for the entire Premises.
The Tenant Improvement Allowance shall be equal to the lesser of (x) the actual
cost of improvements to the office portion of the Premises and the fees and
costs with respect to preparation of the plans and specifications, or (y) 
Thirty Dollars


                                       23

per square foot of the office portion of the Premises up to a maximum of four
thousand seven hundred ninety-six (4,796) square feet of office space for the
Premises (which equals a total of One Hundred Forty Three Thousand Eight Hundred
Eighty-eight Dollars ($143,888)). To the extent that Landlord constructs any
improvements to warehouse portion of the Premises in excess of those enumerated
in section (a)(i)-(ix) and requested by the Tenant, above, and to the extent
that total cost of the improvements to the office portion of the Premises and
the reasonable fees and costs with respect to preparation of the plans and
specifications exceeds the Tenant Improvement Allowance,

         Tenant shall pay the full amount of such excess ("Tenant's Costs") as
         follows:

                  (i) Prior to commencement of construction of the Tenant
         Improvements, Tenant shall pay Landlord an amount equal to one-third of
         the Tenant's Costs, as such amount is then determined by reference to
         the Construction Budget.

                  (ii) When fifty (50%) percent of the Tenant Improvements are
         complete in accordance with the plans and specifications (as verified
         in writing by Landlord's architect), Tenant shall pay Landlord an
         amount equal to the one-third of the Tenant's Costs, as such amount can
         then be reasonably determined by Landlord based on available
         information.

                  (iii) When Tenant Improvements are substantially complete in
         accordance with the plans and specifications (as verified in writing by
         the Landlord's architect), Tenant shall pay the Landlord an amount
         equal to the remaining unpaid balance of Tenant's Costs, as such amount
         can then be reasonably determined by the Landlord based upon available
         information.

         Notwithstanding the foregoing clauses "(i)-(iii)", Tenant may pay the
first Fifty Thousand Dollars of Tenant's Costs in 60 equal monthly installments
of principal in the amount of $833.34, plus interest on principal outstanding
at the rate of twelve percent (12%) per annum, commencing on the Rent
Commencement Date and continuing through the Expiration Date of the initial
term; provided, however, all such principal amounts outstanding thereunder
shall be due and payable in full on or before the earlier of (a) a default on
the part of Tenant occuring under this Lease, or (b) the termination or
expiration of this Lease. Such payments shall be made concurrently with
payments of Minimum Rent under the Lease and shall be considered as Additional
Rent due under the Lease. If Tenant elects to pay such portion of Tenant's
Costs in installments as set forth in the two immediately preceeding sentences,
all other sums owed with respect to Tenant's Costs shall be due and payable on
or before the date upon which construction of Tenant Improvements is commenced.

         Tenant's Costs represent a reimbursement of monies expended by Landlord
on Tenant's behalf. Payment when due shall be a condition to Landlord's
continued performance under this Work Letter and this Lease. Any delay in
construction of the Tenant Improvements or in Tenant taking occupancy of the
Premises resulting from Tenant's failure to make any Tenant's Costs payments
when due shall be Tenant's responsibility. Tenant's failure to pay any portion
of Tenant's Costs when due shall constitute a default under the Lease (subject
to any applicable notice requirements or grace periods), entitling Landlord to
all of its remedies thereunder.

         (f) Tenant's Costs shall include, without limitation, any and all
impact and connection fees payable to Dade County if the amount of square
footage constituting the office portion of the Premises exceeds twenty-five
(25%) percent of the rentable area of the Premises.

         IN WITNESS WHEREOF, Landlord and Tenant have executed this Work
Letter as of the day and first year above written

         leases executed by Landlord with new tenants of comparable space in the
         Beacon Centre within the twelve-month period immediately preceding
         commencement of the Renewal Terms. If Landlord has not executed any
         lease with new tenants within said twelve-month period, the new
         prevailing market rental rate determination shall be based on new
         leases for premises comparible to the Premises herein, as executed
         within said twelve month period by owners of other industrial building
         properties located in west Dade County, Florida. However, in no event
         shall Minimum Rent for any year of the Renewal Term be less than the
         amount of Minimum Rent for the immediate prior year.

           ADDENDUM (this "Addendum") TO LEASE DATED October 26, 1994
              (the "Lease") BETWEEN NEW WORLD PARTNERS JOINT VENTURE
            (the "Landlord") AND ROSS WHITE ENTERPRISES, INC., D/B/A
              NATIONAL COMPUTER DISTRIBUTORS, INC. (the "Tenant")



1. The parties are entering into the Lease contemporaneously with the execution
of this Addendum and desire to modify the terms of the Lease as set forth in
this Addendum. Except as set forth in this Addendum, the Lease is and shall
remain in full force and effect. References to the Lease contained in the Lease,
or in any other instrument, shall be deemed to refer to the Lease as amended by
this Addendum. All capitalized terms utilized in this Addendum and not defined
in this Addendum shall have the respective meanings ascribed to such terms in
the Lease.

2. Section 17 of the Lease Summary is amended to provide that in addition to the
$20,000 security deposit called for in such Section 17, the Tenant shall also
deposit with the Landlord an additional amount of $17,304.16 which shall in all
cases be treated as a security deposit under Section 2.6 of the Lease; provided,
however, if no default has occurred by the Tenant under the Lease, then, the
Tenant's deposit shall be reduced to $20,000 and any excess returned to the
Tenant, within ten (10) days of the Tenant delivering to Landlord a certificate
from the president and chief financial officer of Tenant (in their individual
and corporate capacities) stating that as of the end of the Tenant's last fiscal
quarter, the Tenant had a "Tangible Net Worth" of not less than $6,250,000. For
purposes of this Addendum, "Tangible Net Worth" means (a) the aggregate amount
of all assets of the Tenant which should, in accordance with generally accepted
accounting principles, be classified as assets, other than goodwill, patents,
trademarks, copyrights, franchises, licenses and such other assets as are
properly classified as "intangible assets"; less (b) the aggregate amount of all
liabilities of any kind (including, without limitation, any subordinated debt or
liabilities) of the Tenant.

The parties have executed this Addendum as of October 26, 1994.
