  • Commercial Lease. Start a state-specific lease for the rental of commercial property. Specify the term and rent due, as well as whether the landlord or tenant is responsible for property taxes, insurance, and maintenance and repairs.
  • Commercial Sublease. When a tenant vacates commercial property before the lease term has expired, it may be able to rent the premises to a third party. The tenant would be the sublessor and the third party would be the sublessee. Besides preparing a sublease, both parties will want to review the provisions for assignment or subletting in the original lease agreement between the landlord and the sublessor.
  • Sublease Agreement. Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.
  • Triple Net Lease. Triple net leases are a type of commercial leases where the tenant has to pay for property taxes, insurance, utilities, and maintenance, in addition to the monthly rent.
  • Office Space Lease. When renting an office space, tenants should understand the amount of the rent and duration of the lease. Other important terms include whether the space can be subleased, which parties are responsible for maintenance, and whether any furniture and furnishings will be provided.

            approximated Rentable Area set forth above) per year payable monthly
            in advance, beginning on the Rent Commencement Date without
            deduction or offset, on the first day of each calendar month
            together with applicable sales tax and applicable local taxes, in
            equal installments of Fifty Nine Thousand Three Hundred Twenty and
            87/100 Dollars ($59,320.87) each together with applicable sales tax
            and applicable local taxes, beginning on the Commencement Date.
            Notwithstanding the foregoing, provided that so long as no Event of

            with respect to an undivided portion of the Premises equal to 71,594

            Rent in the First Lease Year, to the extent detailed in the

            Event of Default not having occurred during the balance of the
            Initial Term of this Lease. The entire Overhead Rent otherwise due
            and payable during the Initial Term Free Rent Period shall become

("Third Party Offer"), then Landlord shall advise Tenant, in writing, of
Landlord's intention to accept such Third Party Offer and shall furnish to
Tenant all of the basic terms and conditions of such Third Party Offer (the
"Landlord's Notice"). Tenant shall thereafter have the option, within seven (7)
business days following Tenant's receipt of Landlord's Notice, to exercise its
Right of First Refusal to lease not less than the entire Expansion Premises
(notwithstanding a Third Party Offer for the lease of less than all of the
Expansion Premises) upon the terms contained in the BONA-FIDE third party offer
that is recited in the Landlord's notice, by giving notice of its election to
exercise its Right of First Refusal in writing to Landlord (the "Tenant's
Acceptance"). If Tenant timely exercises the right of first refusal, Landlord
and Tenant shall, within five (5) business days thereafter, enter into an
amendment to this Lease affirming the covenants and conditions contained in this
Lease, except that the

                                     Page 2

amendment, with respect to the Expansion Premises shall contain the applicable
business terms and conditions as contained in the Third Party Offer, Tenant
shall also deliver to Landlord an original signed re-affirmation of the
Guarantor's Guaranty in form and substance reasonably prescribed by Landlord. If
Tenant waives or fails to exercise its Right of First Refusal herein granted in
strict compliance with the terms for said exercise, the Landlord may then lease
such portion of the Expansion Premises as set forth in such offer to any other
party, including the third party offerer and the Right of First Refusal shall
thereafter be terminated on a self-effectuating basis and be of no further force
or effect with respect to such space which is leased to such third-party.
Notwithstanding the immediately preceding sentence, Landlord may, additionally,
request the Tenant to execute a written certification of the lapse and
termination of the Right of First Refusal as herein contained with respect to
such space. Notwithstanding the foregoing, and in the absence of an Event of
Default by Tenant, the Right of First Refusal herein granted to Tenant shall
continue in full force and effect as to the remaining balance of the Expansion
Premises not otherwise leased to third-parties following a failure or waiver on
the part of Tenant to exercise the Right of First Refusal herein granted, said
Right of First Refusal in all other manners remaining subject to the terms and
limitations contained in this Section 1.B.(iv).

                  C. NO RESERVATION. Except as herein specifically provided in
Section 1.B. and this Section 1.C., nothing herein shall constitute a
reservation or other rights in or to the Expansion Premises or shall impose an
obligation on the Landlord to abstain or refrain from marketing the Expansion
Premises for lease to third-parties. Subject to those specific rights granted
Tenant in Sections 1.B. and 1.C. the Landlord shall, during the first twelve
(12) months of the Right of First Refusal, reasonably limit its primary
marketing of the Expansion Premises for lease to only prospective tenants
expressing an interest in leasing a minimum of 100,000 rentable square feet
notwithstanding which Landlord may accept a bona-fide offer for the Lease of not
less than 50,000 rentable square feet from any such prospective Tenant. However,
in the event that Landlord does not, from time to time, have an inventory of
equivalent rentable area of approximately 100,000 rentable square feet in
Buildings 012, 013, 021, 022, or 023, the Landlord may primarily market the
Expansion Premises without limitations hereinabove contained.

                  D. REDUCTION/SUBSTITUTION OF EXPANSION PREMISES. At any time
prior to an exercise by the Tenant of the Initial Expansion Premises Option, or
Second Expansion Premises Option, the Landlord reserves the right to reduce the
square footage of the Expansion Premises by approximately 27,000 usable square
feet in the northern portion of the Expansion Premises. Such reduction shall be
effectuated in order to permit the Landlord to enter into a lease or leases to
other entities. In the event that the Landlord exercises its right to reduce a
portion of the Expansion Premises as hereinabove provided, the Landlord shall
designate equivalent square footage which designated substitute space shall be
contiguous space to other space occupied by Tenant. For purposes of the
immediately preceding sentence, the term "contiguous space" shall be defined as
such rentable square footage which is not subject to the tenancy of an
intervening tenant or other occupant but may, however, be subject to an
intervening corridor separating the existing space occupied by tenant and the
substituted space. Landlord's obligation to substitute Expansion Premises during
the pendency of the First Expansion Premises Option and the Second Expansion
Premises Option shall terminate on December 31, 1999.

                  E. STAND-BY EMERGENCY GENERATOR ASSESSMENT FEE.

         Tenant may contract with Landlord, its assigns or Landlord's designated
provider to supply the Expansion Premises with emergency electric generator
power through the auspices of one or more stand-by emergency generators (as more
specifically defined and discussed in Section 8.A.(2)) upon the payment of an
Emergency Generator Assessment Fee for the Expansion Premises. The Landlord
represents and warrants that it shall be capable of providing the necessary load
but that the obligation of the Landlord to provide emergency generator power
shall be conditioned upon the economic feasibility of the cost of availing
Tenant's load requirements to the cost of providing the load requirement. By way
of example, but not limitation, if, in order to meet the Tenant's load
requirement of .5 mega-watts, the smallest generator available to be purchased
by the Landlord is for 1.5 mega-watts, the Landlord will not be responsible for
providing such additional emergency generator unless Tenant agrees to pay the
capital cost of acquiring the 1.5 mega-watt generator.

         Notwithstanding the preceding paragraph, provided Tenant notices
Landlord of its exercise of the Option to lease the Expansion Premises not later
than June 30, 1999, the Landlord will provide Tenant with an improvement
allowance credit of $500,000.00 which credit shall be applied to the cost of
providing up to 1.0 mega-watts of emergency electrical generator service to the
Expansion Premises. In the event that the Expansion Premises require an
emergency generator load of in excess of 1.0 mega-watts, any such overage shall
be payable by Tenant at the rate of $500,000.00 per mega-watt. In the event that
Tenant provides the herein required notice of its option to lease all of the
Expansion Premises on June 30, 1999 so as to avail the allowance provided for in
this Section, the Expansion Premises Rent Commencement Date may, at the option
of the Tenant, be calculated pursuant to the terms of Section 1.B.(i)(b) or
1.B.(ii)(c), as applicable.

                  F. WAIVER OF OPTION AND RIGHT OF FIRST REFUSAL. In the event
that the Tenant shall either (i) commit an Event of Default as defined in
Section 23 hereof, or (ii) vacate, abandon or surrender all or any part of the
Premises prior to the expiration date notwithstanding the Tenant's continuing to
pay Rent and in all other manners honoring this Lease, or (iii) assign




                                     Page 3
<PAGE>   12
this Lease or sublease any portion of the Premises to a party which is not an
affiliate as defined in Section 13, then and in that event the First Expansion
Premises Option, the Second Expansion Premises Option and the Right of First
Refusal as contained in this Section 1.B., shall hereinafter terminate and be of
no further force and/or effect.

      2. LEASE TERM; LEASE DATE

                  A. GENERAL. The lease term ("Lease Term") is for the period of
time set forth in the BLI Rider and ending on the Lease expiration date set
forth in the BLI Rider ("Expiration Date"). Tenant's obligation to pay all rent,
including Base Rent, Overhead Rent and Additional Rent, (collectively, "Rent"),
as such terms are hereafter defined, will commence on the Rent Commencement
Date, as set forth in the BLI Rider, subject, however, to the Initial Term Free
Rent Period as defined in Section 3.H.

                  Tenant shall observe and perform all of its obligations under
this Lease from the earlier to occur of the date that the Premises are delivered
to Tenant for the purpose of commencement of the Tenant's improvements to the
Premises or the date Tenant otherwise takes possession of the Premises until the
Commencement Date in the same manner as though the Lease Term began when the
Premises were so delivered to Tenant. Under no circumstances, however, may
Tenant enter into possession of the Premises prior to the earlier to occur of
the date that the Premises are delivered to Tenant for the purpose of
commencement of Tenant's improvements to the Premises. However, notwithstanding
the foregoing, Tenant shall pay for all utilities, as either measured by a
separate meter or as fairly estimated by Landlord, and services consumed by or
on behalf of Tenant prior to the Rent Commencement Date.

                  B. RENEWAL OPTION(S). Landlord grants to Tenant the options
(the "Option(s)") to extend the term of this Lease for two (2) additional
periods of five (5) years each (the "Renewal Term(s)") under the terms set forth
below. Tenant shall not be entitled to exercise the Option(s) unless each of the
following conditions shall be fully satisfied at the time of its exercise: (i)
the Lease shall be in full force and effect; (ii) the Tenant originally named in
this Lease, or a permitted assignee pursuant to Section 13, shall be in
possession of the entire Premises; and (iii) no Event of Default shall have
occurred under any of the material terms, provisions, covenants or conditions of
the Lease. In order to exercise a Renewal Option, Tenant must first make written
demand upon Landlord not less than nine (9) months prior to the expiration date
of the initial Lease Term or the initial Renewal Term, as applicable. Base Rent
for each year of each Renewal Term shall increase by Five Percent (5%) over the
previous year during the Lease or the initial Renewal Term, as applicable and
shall continue to increase in each year thereafter by Five Percent (5%) above
the previous Lease Year until the Expiration Date. In the event that the Tenant
shall fail to timely deliver written demand, as hereinabove provided, this
Renewal Option shall expire on a self-effectuating basis and be of no further
force or effect.

      3. RENT

                  A. BASE RENT. During the Lease Term, Tenant will pay to
Landlord in lawful United States Currency as the base rent for the Premises
("Base Rent") the amounts set forth in the BLI Rider, beginning on the Rent
Commencement Date with same being payable without demand, setoff or deduction,
in advance, on or before the first day of each month, in equal monthly
installments of the amounts set forth in the BLI Rider plus applicable sales and
other such taxes as are now or later enacted. All payments of Base Rent,
Overhead Rent, (and Security Deposits if subsequently applicable during the
Lease Term), and any other sums due from Tenant under this Lease shall be made
by automated clearing house transfer to such account as may be designated (or
re-designated from time to time) by Landlord's written notice. Tenant shall
deliver to Landlord any documents, instrument, authorizations or certificates
required by Landlord to give effect to an automated debiting system whereby any
and all payments by Tenant of Rent shall be debited monthly from Tenant's
account in a bank or financial institution designated by Tenant and credited to
Landlord's bank account as Landlord shall designate from time to time by written
notice. Tenant shall promptly pay all service fees and other charges connected
therewith, including, without limitation, any charges resulting from
insufficient funds in Tenant's bank account or any charges imposed upon
Landlord. In the event that Tenant elects to designate a different bank or
financial institution from which any Rent under the Lease is automatically
debited, notification of such change and required documents, instruments,
authorizations and certificates must be received by Landlord not later than
thirty (30) days prior to the date such change is to become effective. Tenant
agrees that it shall remain responsible to Landlord for all payments of Rent and
any other charges pursuant to this Lease, even if Tenant's bank account is
incorrectly debited in any given month. Such Rent shall be immediately payable
to Landlord upon written demand and any failure to so pay subject to the grace
provisions set forth in Section 3 shall constitute an Event of Default.

                  B. OVERHEAD RENT. Beginning on the Rent Commencement Date, and
continuing thereafter during the term of this Lease, Tenant shall pay Tenant's
Share, as defined in the BLI Rider, of (i) the total amount of the annual
Operating Expenses (as hereafter defined) and (ii) the total amount of Taxes (as
hereafter defined). As used herein, "Overhead Rent" means the total of Tenant's
allocated Share of Operating Expenses and Taxes. The Overhead Rent for the first
calendar year hereunder, or portion thereof, shall be set at Four and 50/100
Dollars ($4.50) per square foot of Rentable Area ("Base Year Overhead Rent").
However, in no event shall the Tenant's Share of the Controllable Operating
Expenses be increased by more than Eight Percent (8%) on an on-going cumulative
basis from that charged to Tenant as part of Overhead Rent, for the immediately
preceding calendar year. Increases in Operating Expenses

                                     Page 4
<PAGE>   13
that are not deemed controllable as defined hereunder shall not be limited by
the foregoing sentence. Controllable Operating Expenses do not include (i)
Taxes, (ii) utility charges and fees (including, but not limited to, water,
sewer, electrical, telephone, chilled water and ventilation and air-conditioning
charges, cable communications and the like), (iii) premiums for insurance, (iv)
minimum wage changes, and (v) costs resulting from changes in law. In no event
shall the Overhead Rent to be paid by Tenant in any calendar year be less than
the First Lease Year Overhead Rent (i.e., $4.50 per rentable square foot). For
purposes of example of the manner of calculating the maximum increase in the
non-controllable Overhead Rent on an accumulative on-going basis: if the
increase in the Controllable Overhead Rent in the Second Lease Year is Five
Percent (5%) (as opposed to the maximum of Eight Percent (8%)), then, in the
Third Lease Year the maximum increase in the Controllable Overhead Rent shall be
Eleven Percent (11%). Prior to each subsequent calendar year, beginning with the
calendar year immediately following the Base Year, Landlord shall, in advance,
reasonably estimate for each such calendar year the total amount of the Overhead
Rent. In no event shall the Overhead Rent to be paid by the Tenant in any
calendar year be less than the Base Year Overhead Rent. One-twelfth (1/12) of
the estimated Overhead Rent shall be payable monthly, along with the monthly
payment of the Base Rent. On or before March 31 following a calendar year for
which Overhead Rent is payable hereunder, Landlord shall provide Tenant with a
reconciliation statement showing the amount of the actual components of Overhead
Rent for the previous calendar year. If the reconciliation statement reflects an
underpayment in either component of Overhead Rent, Landlord shall also deliver
to Tenant an invoice which Tenant shall pay within thirty (30) days following
receipt of such invoice or with the due date of its next monthly payment of
Rent, whichever shall first occur. If the reconciliation statement reflects an
overpayment in either component of Overhead Rent, Tenant shall be entitled to
either, at Landlord's option, a credit against the next payment(s) of Rent in an
amount equal to the overpayment or a refund check from Landlord for such
overpayment. In no event shall the Base Rent under this Lease be reduced by
virtue of this Section (except in the event a credit may be due Tenant under
this Section). For a period of ninety (90) days after receipt of the
reconciliation statement, Tenant shall have the right, upon reasonable advance
notice, to visit Landlord's office in the Building during Business Hours, as
hereafter defined, to inspect its books and records concerning the Overhead
Rent, and within such ninety (90) day period to deliver any specific written
objections to Landlord with respect to any actual overpayment. If Tenant fails
to deliver a specific written objection within such ninety (90) day period,
Tenant shall have waived Tenant's right to object to or make any claim for
return of any overpayment and shall have waived its right to perform any further
inspection of the Landlord's book and records. When calculating annual Taxes,
such calculation shall, with respect to ad valorem taxes, be calculated with
reference to the gross amount set forth in the official tax bill issued by the
appropriate taxing authorities, however, when calculating annual Taxes, such
calculations shall take into account the amount actually paid by Landlord for
such calendar year, subject, however, to an off-set and credit against any such
lesser amount equal to reasonable expenses and costs incurred by Landlord in any
proceeding reducing the annual Taxes from the gross amount set forth in the
official tax bill. In the event the Taxes for any calendar year are in fact
contested by Landlord, however, ultimately the amount payable for that calendar
year shall be the amount found to be payable in a final determination, whether
such final determination is in the form of a pronouncement from the appropriate
tribunal or a settlement, together with attorneys' fees and costs, appraisal
costs and other fees and costs incurred by the Landlord utilizing a standard of
commercially reasonable management decision in protesting or contesting the
amount of such Taxes. Further, all such fees and costs incurred in the
immediately preceding sentence shall be commercially reasonable in the market
place. The delivery of the aforedescribed projection statement after January 1
and/or the reconciliation after March 31 shall not be deemed a waiver of any of
Landlord's or Tenant's rights to collect monies and/or a waiver of any of the
duties and obligations of Tenant or Landlord as described in this section or as
provided elsewhere in the Lease. As used in this paragraph 3., the following
terms shall have the following meanings:

                           (1)      The term "Operating Expenses" shall mean
(i) any and all costs of ownership, management, operation, repair and
maintenance of the Building, and its services, including, without limitation,
wages, salaries, professionals' fees, taxes, insurance, benefits and other
payroll burdens of all employees to the extent that such employees are directly
involved with the management or maintenance of the Building, Building Management
fees (which Building Management Fees shall not exceed Five Percent (5%) of the
gross receipts for such calendar year.) For purposes of this provision, Gross
Receipts for any calendar year shall mean an amount equal to the product of (i)
the average annual gross rents, charges and fees per rentable square foot
payable under all leases in effect for the Building for the calendar year, and
(ii) the number of rentable square feet in the Building actually rented against
a minimum of Ninety Five Percent (95%) of the rentable square feet in the
Building, Common Area janitorial, maintenance, guard and other services,
building management office rent or rental value, power, life safety equipment
and systems, fuel, water, waste disposal, chilled water, ventilating and air
conditioning charges, stand-by emergency generator maintenance, leases or
financing for the acquisition of furniture and/or equipment, upkeep, monitoring,
refueling charges, landscaping care, lighting, garbage removal, window cleaning,
system maintenance, parking area care, fees and assessments paid to or on behalf
of the "Association" (as later defined herein), and any and all other utilities
not separately metered for the Premises or a portion thereof, materials,
supplies, maintenance, repairs, insurance applicable to the Building and
Landlord's personal property and depreciation on personal property, and (ii) the
cost (amortized, with interest at the rate of Ten Percent (10%) per annum, over
the lesser of (a) the

                                     Page 5
<PAGE>   14
balance of the Lease (but in no event longer than ten (10) years), or (b) the
useful life of the asset per GAAP); provided, however, that if the balance of
the term of the Lease is less than five (5) years the amortization shall be over
the shorter of the useful life of the item, in accordance with GAAP or five (5)
years, unless, however, the Lease is subsequently renewed in which event the
amortization shall be recalculated during the renewal period on a pro-rata basis
with interest on all amortized periods at the rate of Ten Percent (10%) per
annum of any capital improvements made to the Building by Landlord after the
date of this Lease that reduce in a commercially reasonable manner Operating
Expenses or made to the Building by Landlord after the date of this Lease that
are required under any governmental law or regulation; provided, however, that
Operating Expenses shall not include real property taxes, depreciation on the
Building other than depreciation on carpeting and wallcovering in public
corridors and Common Areas, costs of tenants' improvements, real estate broker's
commissions, initial acquisition and installation costs of the stand-by
emergency generator and related systems, interest and debt service, capital
items other than those referred to in subsection (ii) above. Landlord shall
maintain accounting books and records in accordance with generally accepted
accounting principles. In determining the amount of Operating Expenses for any
calendar year, if less than Ninety Five Percent (95%) of the Building shall have
been occupied by tenants and fully used by them, Operating Expenses shall be
increased to an amount equal to the like operating expenses which would normally
be expected to be incurred had such occupancy been Ninety Five (95%) and had
such full utilization been made during the entire period. Landlord hereby agrees
to deduct each calendar year from the amount of the Operating Expenses the total
amount of any and all sums, amounts or charges paid by Tenant or other tenants
of the Building directly to Landlord or its agent for specific tenant requested
services or specific utility charges, if applicable. In no event shall Tenant be
responsible for the payment, as part of its share of Operating Expenses for
services rendered by Landlord or Landlord's Agent's exclusively to any other
tenant or occupant in the Building. Notwithstanding anything contained in this
Section to the contrary, prior to the separate metering for electricity,
air-conditioning, air-handlers and chilled water services of Tenant's Premises,
instead of including certain utility charges or services in Overhead Rent,
Landlord may, at its option, bill Tenant and Tenant shall pay for those
utilities or services in any one or a combination of the following manners: (i)
direct charges for services provided for the exclusive benefit of the Premises
that are subject to quantification; (ii) based on a formula that takes into
account the relevant intensity or quantity of use of utilities or services by
Tenant and all other recipients of the utilities, as reasonably determined by
Landlord; or pro-rata based on the proportion that the rentable area of Premises
bears to the total rentable area of the tenant premises within the Building that
receive the applicable utilities or services. In addition, Landlord may, instead
of including certain utility charges in Overhead Rent, provide for direct
delivery of the applicable utility services to Tenant by the utility providers.
If so, all costs and expenses, including all applicable utility deposits,
incurred in connection with provision of the applicable utility services to
tenants, including all costs associated with the provision of separate meters to
tenant premises, shall be includible in Overhead Rent or paid by Tenant and the
other tenants receiving the meters in amounts as reasonably allocated by
Landlord, and, after the direct provision of the utility services has been
effective, the applicable utility charges for ongoing service shall not be
included in Operating Expenses.

                  Notwithstanding anything to the contrary in the definition of
"Operating Expenses", Operating Expenses shall not include any of the following:

         (a) Legal fees, brokerage fees, leasing commissions, advertising costs
and other fees paid to third-party professionals associated with the renting of
the Premises or other space in the Building.

         (b) Damage and/or repairs necessitated by the negligence or wilful
misconduct of Landlord or any agent of Landlord.

         (c) Legal fees, accounting fees or other expenses related to the
defense of Landlord's title to or interest in the Premises or the Building.

         (d) Payment of debt service on loans secured by a mortgage or lien
encumbering the Building or any portion or interest of or in the Building.

         (e) All costs and expenses which have been paid by Landlord and
reimbursed directly to Landlord by third-parties, including other tenants in the
Building, rather than through Operating Expenses.

                           (2) The term "Taxes" shall mean the gross amount of
all impositions, taxes, assessments (special or otherwise), water and sewer
assessments and other governmental liens or charges of any and every kind,
nature and sort whatsoever, ordinary and extraordinary, foreseen and unforeseen,
and substitutes therefor, including all taxes whatsoever (except for taxes for
the following categories which shall be excluded from the definition of Taxes:
any inheritance, estate, succession, transfer or gift taxes imposed upon
Landlord or any income taxes specifically payable by Landlord as a separate
tax-paying entity without regard to Landlord's income source as arising from or
out of the Building and/or the land on which it is located) attributable in any
manner to the Building, and the approximately 350 acre portion of the property
surrounding the building, shown on Exhibit "G" hereto (but excluding the
assessed value of any new building(s) and the land allocated to such new
building(s) constructed on such campus), or the rents (however the term may be
defined) receivable therefrom, or any part thereof, or any use thereon, or any
facility located therein or used in conjunction therewith or any charge or other
amount required to be paid to any governmental authority, whether or not any of
the foregoing shall be designated "real estate tax", "sales tax", "rental tax",
"excise tax",

                                     Page 6
<PAGE>   15
"business tax", or designated in any other manner. For purposes hereof, until
such time as a separate tax folio is established for the Building and the
approximate 350 acre campus, the taxes on the land which encompasses the 350
acre campus and other improvements shall be calculated in a fair and equitable
manner by determining the assessed value of the 350 acres based upon the present
total assessment on the tax folio of which the 350 acres are a constituent part.

         Tenant hereby agrees that the Overhead Rent from time to time computed
by Landlord shall be final and binding for all purposes of this Lease unless,
within ninety (90) days after Landlord provides Tenant with written notice of
the amount thereof, Tenant provides Landlord with written notice (i) disputing
the mathematical accuracy of such amount (the "Disputed Amount"), (ii)
designating an attorney or accountant, reasonably acceptable to Landlord, and
appointed by Tenant, at its sole cost and expense, to review the mathematical
accuracy of the Disputed Amount with Landlord and/or its designated
representatives and (iii) confirming that the Disputed Amount shall not be
subject to adjustment and agreeing to pay all of Landlord's third party costs
and expenses in connection with such review, including attorneys' fees and
accountants' fees, unless as a result thereof the Disputed Amount is
demonstrated to reflect a mathematical error of Five Percent (5%) or more. In
the event, to the contrary, as a result thereof the Disputed Amount is
demonstrated to reflect a mathematical error in excess of Five Percent (5%), the
Landlord shall pay Tenant's reasonably incurred third-party costs and expenses
in connection with such review, including attorney's fees and accounting fees.
In all cases, the costs and expenses to be reimbursed by either party to the
other above shall be at commercially reasonable and competitive rates. Landlord
hereby agrees, in the event it receives such notice from Tenant, to cooperate in
promptly completing such review and each party agrees respectively to correct
any discrepancy (i.e., a refund by the Landlord in the event of a Tenant
overpayment or an additional payment by the Tenant in the event of an
underpayment promptly upon the completion of the review). Tenant shall have no
right to audit Overhead Rent unless such is in excess of Base Year Overhead
Rent. Such an audit may be conducted at any time within ninety (90) days after
Landlord's annual statement is delivered to Tenant for such calendar year,
provided, that Tenant shall give Landlord not less than ten (10) days prior
written notice of any such audit and sign a confidential non-disclosure
agreement prior to the audit which confidential non-disclosure agreement shall,
however, notwithstanding any provisions to the contrary, allow for the
disclosure of information received during the audit in the event such disclosure
is required by a governmental rule or regulation, or in the event of discovery
in the course of litigation under this Lease.

                  C. LATE CHARGE. Tenant covenants and agrees to pay a late
charge in the amount of Five Percent (5%) of any payment of Rent not received by
Landlord on or before the date when same is due in the event that Rent is not
received more than two (2) times during any calendar year. Tenant shall also pay
Landlord interest at a rate equal to Twelve Percent (12%) per annum accruing on
any Rent(s) outstanding. Tenant shall pay Landlord any such late charge(s) or
interest within five (5) days after Landlord notifies Tenant of same.

                  D. DEFINITION OF RENT. The term "Rent" shall refer
collectively to Base Rent, Overhead Rent and Additional Rent. The term
"Additional Rent" is sometimes used herein to refer to any and all other sums
payable by Tenant hereunder, including, but not limited to, parking charges for
other than surface parking for which there is no charge (if, in the future, the
Landlord shall construct a parking structure in which Tenant wishes to lease
parking spaces) and sums payable on account of default by Tenant. All Rent shall
be paid by Tenant without offset, demand or other credit, and shall be payable
only in lawful money of the United States of America which shall be legal tender
in payment of all debts and dues, public and private, at the time of payment.
All sums payable by Tenant hereunder, to the extent not required to be paid by
automated clearinghouse transfer as provided in Sections 3.A. and 3.B. herein,
shall be paid by check against a financial institution located in the United
States of America. Such Rent shall be paid by Tenant at the Building management
office located in the Building or elsewhere as designated by Landlord in writing
to Tenant. Any Rent payable for a portion of a month shall be prorated based
upon the number of days in the applicable calendar month. Unless otherwise
expressly provided, all monetary obligations of Tenant to Landlord under this
Lease, of any type or nature, other than Base Rent (i.e., Overhead Rent, or
Additional Rent) shall be subject to the same rights and remedies reserved to
Landlord in the case of an Event of Default in the payment of same as provided
in this Lease for Events of Default in the payment of Base Rent.

                  E. RENT TAXES. In addition to Base Rent and Overhead Rent,
Tenant shall and hereby agrees to pay to Landlord each month a sum equal to any
sales tax, tax on rentals and any other similar charges now existing or
hereafter imposed, based upon the privilege of leasing the space leased
hereunder or based upon the amount of rent collected therefor.

                  F. RENT COMMENCEMENT OTHER THAN FIRST DAY. If the Rent
Commencement Date occurs on any day other than the first day of the month, or if
the Lease Term ends on a date other than the last day of a calendar month,
Tenant shall occupy the Premises under the terms of this Lease and the pro rata
portion of the Rent shall be paid by Tenant; provided, however, that in such an
event the Lease Commencement Date, for the purposes of this Lease, shall be
deemed to be the first day of the month immediately following the month in which
possession is given.

                  G. OVERHEAD RENT AFTER EXPIRATION DATE. Overhead Rent for the
final months of this Lease is due and payable even though it may not be
calculated until subsequent to the Expiration Date of the Lease. Tenant
expressly agrees that in the event the Tenant shall

                                     Page 7
<PAGE>   16

have delivered a Security Deposit under this Lease, the parties acknowledging
however that a Security Deposit is waived at the time of the execution of this
Lease, Landlord, at Landlord's sole discretion, may apply the Security Deposit,
as defined in the BLI Rider, in full or partial satisfaction of any Overhead
Rent due for the final months of this Lease. If said Security Deposit is greater
than the amount of any such Overhead Rent and there are no other sums or amounts
owed Landlord by Tenant by reason of any other terms, provisions, covenants or
conditions of this Lease, then Landlord shall refund the balance of said
Security Deposit to Tenant as provided herein. Nothing herein contained shall be
construed to relieve Tenant, or imply that Tenant is relieved, of the liability
for or the obligation to pay any Overhead Rent due for the final months of this
Lease by reason of the provisions of this paragraph, nor shall Landlord be
required first to apply said Security Deposit to such Overhead Rent if there are
any other sums or amounts owed Landlord by Tenant by reason of any other terms,
provisions, covenants or conditions of this Lease.

                  H. INITIAL TERM FREE RENT PERIOD. Beginning on the Rent
Commencement Date and ending twelve (12) months thereafter (such period herein
referred to as the "Initial Term Free Period"), Tenant shall not be obligated to
pay Base Rent with respect to the entire Premises and no Overhead Rent, with
respect to an undivided portion of the Premises equal to 71,594 Rentable Square
Feet of the Premises. Tenant hereby acknowledges and agrees that Landlord's
waiver of Base Rent and Overhead Rent, as herein provided, are conditioned upon
an Event of Default not having occurred during the Initial Term Free Rent Period
and thereafter during the Initial Term of this Lease. The entire Base Rent and
Overhead Rent otherwise due and payable during the Initial Term Free Rent Period
shall become immediately due and payable upon the occurrence of an Event of
Default by Tenant under this Lease.

         4. SECURITY DEPOSIT

         No Security Deposit is initially required by the Landlord to be funded
by the Tenant in consideration and reliance of financial documentation submitted
by the Tenant. However, in the event that, subsequent to the execution of this
Lease, the Tenant shall have delivered a Security Deposit, the Security Deposit
shall not be considered an advance payment of rent and is not intended to serve
as liquidated damages nor to be a measure of Landlord's damages for any default
by Tenant. If a Security Deposit is later stipulated to be delivered by Tenant,
in any instance by way of example where the Landlord is willing to extend the
time for the cure of a default or the delivery of a Security Deposit is in
consideration for a concession delivered by Landlord, and such Security Deposit
will be retained by Landlord as security for the payment by Tenant of the Rent
and Additional Rent and for the faithful performance by Tenant of all the other
terms and conditions of this Lease. In the event Tenant fails to faithfully
perform the terms and conditions of this Lease, Landlord, at Landlord's option,
may at any time apply the Security Deposit or any part thereof toward the
payment of the Rent and/or Additional Rent and/or toward the performance of
Tenant's obligations under this Lease; in such event, within five (5) days after
notice, Tenant will deposit with Landlord funds sufficient to restore the
Security Deposit to its original amount. The Security Deposit is not liquidated
damages. Landlord will return the unused portion of the Security Deposit to
Tenant within sixty (60) days after the Expiration Date if Tenant is not in
violation of any of the provisions of this Lease. Landlord may (but is not
obligated to) exhaust any or all rights and remedies against Tenant before
resorting to the Security Deposit. Landlord will not be required to pay Tenant
any interest on the Security Deposit nor hold same in a separate account. If
Landlord sells or otherwise conveys the Building, Landlord will deliver the
Security Deposit or the unapplied portion thereof to the new owner. Tenant
agrees that if Landlord turns over the Security Deposit or the unapplied portion
thereof to the new owner Tenant will look to the new owner only and not to
Landlord for its return upon expiration of the Lease Term. If Tenant assigns
this Lease with the consent of Landlord, the Security Deposit will remain with
Landlord for the benefit of the new tenant and will be returned to such tenant
upon the same conditions as would have entitled Tenant to its return.

         5. USE

                  A. GENERAL. Tenant will use and occupy the Premises solely
for the operation of the business set forth in the BLI Rider and for no other
use whatsoever. Tenant acknowledges that its type of business, as above
specified, is a material consideration for Landlord's execution of this Lease.
Tenant will not commit waste upon the Premises nor suffer or permit the Premises
or any part of them to be used in any manner, or suffer or permit anything to be
done in or brought into or kept in the Premises or the Building, which would:
(i) violate any law or requirement of public authorities, (ii) cause injury to
the Building or any part thereof, (iii) interfere with the peaceful use or
occupancy of any other tenant in the Building or their patrons or interfere with
the normal operations of air-conditioning, plumbing or other mechanical or
electrical systems of the Building or the elevators installed therein, (iv)
constitute a public or private nuisance, or (v) alter the appearance of the
exterior of the Building or of any portion of the interior other than the
Premises pursuant to the provisions of this Lease. Landlord represents that the
property on which the Building is located is currently zoned Light Industrial
Research Park (LIRP) by the City of Boca Raton and that the use of the Premises
set forth in the BLI Rider is not in violation of such zoning.

                  B. PROHIBITED USES. Notwithstanding anything to the contrary
in this Lease or the BLI Rider, including but not limited to, the "Use of
Premises" Section of the BLI Rider, Tenant hereby represents, warrants and
agrees that Tenant's business is not and shall not be, and that Tenant shall not
use the Premises or any part thereof, or permit the Premises or any part thereof
to be used, (i) for the business of photographic, multilith or



                                     Page 8

or for the preparation, dispensing or consumption of food or beverages in any
manner whatsoever, (vii) as a news or cigar stand, (viii) as an employment
agency, labor union office, physician's or dentist's office, dance or music
studio, school (except for the training of employees of Tenant), (ix) as a
barber shop or beauty salon, (x) for the business of (a) operating a shared
office facility, that is, a business which subleases space and/or offers
centralized services to subtenants or customers on a shared basis, such as
secretarial, receptionist, telephone, etc., or (b) for a fee to persons inside
or outside of the Building, providing as a service word processing, secretarial,
video conferencing, conference services, telephone answering, receptionist or
mail receipt services, (xi) for any services or uses to the general public to be
conducted on the Premises, (xii) amateur recreational uses or movie theaters,
(xiii) retail sales, including but not limited to drug stores or florists, or
(xiv) showroom and wholesale uses. Nothing in this Section shall preclude Tenant
from using any part of the Premises for photographic, multilith or multigraph
reproductions to the extent that such uses are incidental to Tenant's own
business or activities.

         6. ACCEPTANCE OF PREMISES

         Tenant has examined the Premises and accepts delivery of the Premises
in an "As-Is" condition. However, in the event that during the course of the
Tenant performing the Tenant's Work, in accordance with the Work Letter, the
Tenant notices the Landlord of any violations of building code or other
applicable governmental regulations in regard to the Premises or the Building,
Tenant will not be responsible for any costs or expenses incurred in the
remediation of any such violations and any said costs shall likewise not be
included in, Operating Expenses as the term is defined in Section 3.B.(1) of
this Lease. Landlord will promptly correct any such violation at Landlord's sole
cost and expense. Notwithstanding the foregoing, the Tenant hereby acknowledges
that any items provided to the Premises by Landlord shall remain the property of
the Landlord and, at the termination of this Lease, be returned to the Landlord
in working condition, normal wear and tear excepted, subject to the useful life
of any such item ending during the Lease Term. All existing ceiling system and
demountable partitions are to remain in the Premises at the time of the delivery
of the Premises and may be utilized by Tenant without charge. Improvements, if
any, to be made to the Premises by Tenant shall be made in accordance with the
Work Letter. Landlord shall provide Tenant with Landlord's pre-approved list of
architects for purposes of preparation of plans in accordance with the Work
Letter. In addition thereto, and in accordance with that certain Letter
Agreement, dated November 12, 1997, between Blue Lake, Ltd. and William B.
Reichel. Landlord has stipulated Nichols Page Architect, Inc. as a permitted
architect for said purposes. All leasehold improvements (as distinguished from
trade fixtures and apparatus) installed in the Premises at any time, whether by
or on behalf of Tenant or by or on behalf of Landlord, shall not be removed from
the Premises at any time, unless such removal is consented to in advance by
Landlord; and at the expiration of this Lease (either on the Termination Date or
upon such earlier termination as provided in this Lease), all such leasehold
improvements shall be deemed to be part of the Premises, shall not be removed by
Tenant when it vacates the Premises, and title thereto shall vest solely in
Landlord without payment of any nature to Tenant. All trade fixtures and
apparatus (as distinguished from leasehold improvements) owned by Tenant and
installed in the Premises shall remain the property of Tenant and shall be
removable at any time, including upon the expiration of the Term; provided
Tenant shall not at such time have committed an Event of Default, and provided
further, that Tenant shall repair any damage to the Premises caused by the
removal of said trade fixtures and apparatus and shall restore the Premises to
substantially the same condition as existed prior to the installation of said
trade fixtures and apparatus. The taking of possession by Tenant (or any
permitted assignee or subtenant of Tenant) of all or any portion of the Premises
for the conduct of business will be deemed, subject to provisions of other
Sections of this Lease and this Section 6, conclusive evidence that Tenant has
found the Premises, and all of their fixtures and equipment, acceptable.

         Notwithstanding anything contained in this Section 6 to the contrary,
the Landlord shall be and remain responsible for, as of the date of delivery of
the Premises, (i) structural defects, and (ii) the Premises' compliance with all
applicable and governing laws, rules and regulations as to the Premises as of
the date of the delivery of possession of the Premises. The responsibility of
Landlord may, however, be subject to being diminished or terminated in the event
of an exacerbation of any of the foregoing by virtue of acts or omissions by the
Tenant following knowledge of the Tenant of any such defects or noncompliance.
As of the date hereof the Premises comply in all material respects with all
applicable Environmental Laws.

         7. PARKING

                  A. RESERVED SURFACE PARKING. Twenty (20) surface parking
spaces shall be reserved for Tenant's employees and guests, at a mutually
agreeable location reasonably proximately located to the east side of the
portion of the Building containing Premises "A".

                  B. RESERVATIONS. Subject to the applicable provisions of
Section 7.A. above, Landlord has and reserves the right to alter the methods
used to control parking and the right to establish such controls and rules

                                     Page 9
<PAGE>   18
and regulations (such as parking stickers to be affixed to vehicles) regarding
parking that Landlord may deem desirable. Without liability, Landlord will have
the right to tow or otherwise remove vehicles improperly parked, blocking
ingress or egress lanes, or violating parking rules, at the expense of the
offending tenant and/or owner of the vehicle.

                  C. CONDITIONS. Tenant's right to use, and its right to permit
its principals and guests to use, the parking facilities pursuant to this Lease
are subject to the following conditions: (i) Landlord has made no
representations or warranties with respect to the parking area, except as set
forth in (ii) hereof, the number of spaces located therein or access thereto;
(ii) Landlord reserves the right to reduce the number of spaces in the parking
area, but, in no event, to less than three (3) spaces per 1,000 rentable square
feet, further provided that the parking spaces shall be unreserved, used in
common with other tenants, readily accessible to the Premises and at no charge
to Tenant, but, in no event shall Landlord impose any such permitted reduction
so as to adversely effect Tenant unilaterally other than in a manner equally
impacting all tenants to the extent reasonable; and none of the foregoing shall
entitle Tenant to any claim against Landlord or to any abatement of Rent (or any
part thereof); (iii) Landlord has no obligation to provide a parking lot
attendant and Landlord shall have no liability on account of any loss or damage
to any vehicle or the contents thereof, Tenant hereby agreeing to bear the risk
of loss for same; (iv) Tenant, its agents, employees and invitees, shall park
their automobiles and other vehicles only where and as designated from time to
time by Landlord within the parking area; and (v) if and when so requested by
Landlord, Tenant shall furnish Landlord with the license numbers of any vehicles
of Tenant, its agents and employees.

                  D. COVERED PARKING. So long as no condition referred to in
Section 1.F. shall have occurred, Tenant may, subject to the restrictions and
conditions herein contained, at its sole expense, contract with the Landlord to
construct ten (10) to twelve (12) parking spaces, the number of parking spaces
being based upon existing parking lot configuration, at a mutually agreed upon
location on the south side of the portion of the Building containing the
Premises, which may be covered by canopies or other Landlord approved form of
covering for parking spaces, which approval shall not be unreasonably withheld
or delayed, which will thereupon be reserved to the Tenant. The design and
manner of construction of the covering of the parking spaces shall be in
conformance with the design of the Building and in conformance with the
structure of the Building (formed concrete) subject to the reasonable approval
of Landlord in addition to the approval of the Building Departments of the City
of Boca Raton and/or the County of Palm Beach, as applicable. The design and
construction of the covering structure shall be exclusively placed to bid by
approved architects and contractors of Blue Lake Corporate Center whose bids
shall be competitive with the market. Tenant shall, at its sole expense, be
solely responsible for, in addition to the construction, the maintenance, upkeep
and repair of any improvement to the parking spaces so as to avail covering of
same. Tenant may contract with Landlord to have Landlord contract for
maintenance and repair, the expense of which shall be that of Tenant. The
covered parking spaces shall be relocated, at Landlord's expense, to a location
reasonably proximate to the southern end of the Premises, upon notice from
Landlord that such relocation is necessitated by any law or regulation or by
virtue of the location of a raised parking facility to be constructed at a
location proximate to the Building.

         8. BUILDING SERVICES

                  A. GENERAL. In general, the services set forth below will be
provided by Landlord at a service level set, defined and regulated by Landlord
consistent with office buildings of similar quality to and in the same immediate
geographic area as the Building. During the Lease Term, the regular business
hours ("Business Hours") of the Building will be 8:00 a.m. to 6:00 p.m., Monday
through Friday, except holidays generally recognized by state and federal
governments or as may be shortened in accordance with applicable policies or
regulations adopted by any utility company servicing the Building or government.
Landlord reserves the right to increase the Business Hours. The Building will be
accessible to Tenant, its subtenants, agents, servants, employees, contractors,
invitees or licensees (collectively, "Tenant's Agents") twenty-four hours per
day, seven days per week except in the case of temporary closure due to
emergencies, repairs, casualty, governmental or quasi-governmental requirements
or as Landlord reasonably deems necessary in order to prevent damage or injury
to person or property.

                           (1) ELECTRICITY: Tenant shall, as part of Tenant's
initial improvements build-out, (all as more specifically provided for in the
Work Letter attached hereto and made a part hereof), pay all applicable security
deposits for electrical services and cause to be installed separate metering to
the Premises, at Tenant's sole cost and expense for electric usage, including,
by sub-meter, air-conditioning, air-handlers and chilled water pursuant to plans
approved by Landlord. It is acknowledged that such separate metering may not
available until completion of all demising work for the Premises by Tenant.
During the Lease Term, separately metered electric power will be available
through the auspices of the Landlord or the exclusive contractor for electric
power at the Building for the purpose of lighting and general office equipment
use in amounts consistent with Building Standard Electric Capacities. Landlord
reserves the right after business hours to turn off all unnecessary lighting in
the unoccupied areas of the Building to minimize the energy consumption of the
Building. Tenant will not, without written consent of Landlord connect with
electric current except through existing electrical outlets in the Premises, any
major apparatus or major device for the purpose of using electric current,
except for Tenant's ability to add a supplemental package air-conditioning unit
as provided in this Section 8. Landlord has advised Tenant that presently,
Florida
                                    Page 10
<PAGE>   19
Power & Light ("Electric Service Provider") is the utility company selected by
Landlord to provide electricity service for the Building. Notwithstanding the
foregoing, if permitted by law, Landlord shall have the right at any time and
from time to time during the Lease term to either contract for service from a
different company or companies providing electric service (each such company
shall hereinafter be referred to as an "Alternative Service Provider") or
continue to contract for service from the Electric Service Provider. Tenant
shall cooperate with Landlord, the Electric Service Provider, and any
Alternative Service Provider at all times and, as reasonably necessary, shall
allow Landlord, Electric Service Provider or any Alternative Service Provider
reasonable access to the Building's electric lines, feeders, risers, wiring and
any other machinery within the Premises.

                           (2) STAND-BY EMERGENCY GENERATOR SERVICE.

         Landlord will construct and operate a Stand-By Emergency Generator on
the grounds of the Building for emergency electrical power on a short-term
emergency basis to those tenants of Blue Lake Corporate Center who, subject to
availability and load requirement, contract to be supplied stand-by emergency
electrical service in the event of a power failure. Tenant has indicated its
desire to have the Premises serviced by the Stand-By Emergency Generator service
effective as of the initiation of the operation of the Stand-By Emergency
Generator. Landlord agrees to provide the services of 1.2 mega-watts of the
Stand-By Emergency Generator to the Premises in consideration for the payment by
the Tenant of the Emergency Generator Assessment Fee in the amount prescribed in
the BLI Rider and to the Expansion Premises, in accordance with the provisions
of Section 1.E. In the event that the Stand-By Emergency Generator is not
operational and in service as of the Rent Commencement Date, the Tenant may, at
its expense, place a temporary/removable emergency electric service generator at
a mutually agreed location on an exterior portion of the Building which location
shall be selected by Landlord subject, however, to the reasonable satisfaction
of Tenant. The location of the placement of Tenant's temporary electrical
generator shall comply with the prescriptions of such agencies of the City of
Boca Raton, Florida, and the County of Palm Beach, Florida, as have jurisdiction
over same. Tenant shall be responsible for all costs incurred by Tenant,
together with all reasonably necessary and verifiable out-of-pocket expenses of
Landlord incurred in the review of plans, licenses and the like for the
electrical generator fuel tanks and other components. In the event Tenant shall
elect to utilize a temporary emergency generator then Tenant shall indemnify and
hold Landlord harmless from and against any claim relating to Tenant's generator
and deliver to Landlord an all-risk comprehensive insurance policy naming
Landlord as an additional insured and loss payee as its interest appear, said
policy having a deductible of not more than Ten Thousand and NO/100 Dollars
($10,000.00), together with an endorsement for boiler and machine insurance
likewise naming Landlord as an additional insured and loss payee as its interest
appears in the minimum amount of Seven Million and NO/100 Dollars
($7,000,000.00), together with an Environmental Pollution Liability Insurance
Policy underwritten by an insurer and in an amount both reasonably acceptable to
Landlord providing coverage for claims of bodily injury, death, property damage
and corrective action.

                           (3) AIR-CONDITIONING  SERVICES.

                  Landlord and Tenant agree that Building's air-conditioning
system is not designed to cool machinery and equipment. Tenant shall not
re-direct, or in any manner modify, the air-conditioning duct distribution to
accommodate Tenant's build-out unless any such modifications are first approved
in writing by the Landlord, which modifications shall be designed only by an
engineer pre-approved by the Landlord. Until such time as the Premises are
separately metered for air-conditioning services, if Tenant requires additional
air-conditioning services for comfort control at times other than during
Business Hours, Landlord will bill Tenant as Additional Rent for the number of
hours used at the Landlord's then standard prevailing rate for after-hours use
of air-conditioning subject, however, to minimum charges prescribed by Landlord
from time-to-time. At the execution of this Lease, the Landlord's after-hours
charge for air-conditioning is $.0006 per square foot of Rentable Area per hour
but, in no event less than Thirty and NO/100 Dollars ($30.00) per hour. This
rate may be subject to change during the Lease Term in Landlord's discretion as
evaluated by FPL Services or a similar services. If Tenant requires additional
air-conditioning services for comfort control at times during or other than
during Business Hours, or in capacities beyond the Building Standard, Tenant
may, at its election, have installed an independent roof-mounted air-to-air unit
to be installed at Tenant's sole cost and expense (including the cost and
expense of additional support for the roof structure) in any portion of the
Premises in which Tenant requires air conditioning on a basis other than during
Business Hours. Tenant acknowledges that Tenant shall pay Landlord or its agents
for any roof installation or removal of the roof-mounted air-to-air system. The
independent unit shall be screened from view. All roof penetration shall be
performed by Landlord at Tenant's expense at charges normal and customary for
such work. Tenant shall submit all plans for any such installation with the
Landlord, who shall not unreasonably withhold approval of any such plans as well
as to the City of Boca Raton or any other authority having jurisdiction relating
to said installation. The Tenant shall deliver a mechanic's lien waiver from all
materialmen, laborers or other potential lienors claiming by or through Tenant
pursuant to F.S. Chapter 713 within ten (10) business days after completion of
the installation. Other than the independent unit, the chilled water and control
systems will remain under the control of Landlord, who will regulate the
systems' setting and adjustment. At Landlord's option, Landlord may secure
air-conditioning controls (thermostats) in lockable metal boxes to regulate the
efficiency and use of the system. The Landlord may, at its

                                    Page 11
<PAGE>   20
option, contract with FPL Services, or such other provider of chilled-water
distribution system sources as the Landlord may elect.

                           (4)      WATER AND SEWER:

                  Landlord agrees to provide municipally supplied cold water and
sewer services to the Premises and the Common Areas for lavatory purposes.
Landlord reserves the right to separately meter water and sewer services.

                           (5)      ELEVATOR SERVICE:

                  If applicable, Landlord will provide elevator service.

                  B. INTERRUPTION OF SERVICES. It is understood and agreed that
Landlord does not warrant that any of the services referred to above, or any
other services which Landlord may supply, will be free from interruption. Tenant
acknowledges that any one or more of such services may be suspended by reason of
accident or repairs, alterations or improvements necessary to be made, or by
strikes or lockouts, or by reason of operation of law, or other causes beyond
the control of Landlord. No such interruption or discontinuance of service will
be deemed an eviction or a disturbance of Tenant's use and possession of the
Premises or any part thereof, or render Landlord liable to Tenant for damages or
abatement of Rent or relieve Tenant from the responsibility of performing any of
Tenant's obligations under this Lease. If, as a result of Landlord's gross
negligence or willful misconduct, Tenant is unable to operate its business in
the Premises as a result of a cessation of a major service to be provided to the
Premises by Landlord as set forth herein for more than five (5) business days,
Rent shall abate until that major service is restored. If, a cessation of a
major service rendering Tenant unable to operate its business in the Premises
for more than five (5) business days is not a result of Landlord's gross
negligence or willful misconduct, the Rent shall abate on a proportionate basis
until that major service is restored. If, as a result of Landlord's gross
negligence or willful misconduct, as set forth herein, the material services are
unavailable for more than ninety (90) continuous days, the Tenant may, upon
thirty (30) days written notice to Landlord, terminate this Lease (unless such
material service is restored within such thirty (30) day period). If such
cessation of a major service is the result of other than Landlord's gross
negligence or willful misconduct, the provisions of Section 17 shall apply.

                  C. FIBER OPTICS. Tenant may contract with BellSouth, which has
been provided exclusive access through the underlying property by Landlord for
telecommunication service wiring and installation and which has been designated
by the Landlord as the vendor of choice at the Blue Lake Building, for voice and
data telecommunication wiring and services, and installing any telecommunication
products and, specifically, dual access points for Tenant's fiber optic lines,
at Tenant's sole expense. To the extent that such installation requires the
digging of a trench through the Property in order to gain dual access points,
the Tenant shall provide the Landlord with plans and schematics for the
referenced installation which plans and schematics shall be subject to the
reasonable satisfaction of the Landlord and which installation shall be further
subject to the approval, as necessary, of the City of Boca Raton or other
agencies having jurisdiction thereon.

                  D. CONDUIT CONNECTION. Landlord shall, in accordance with the
Work Letter dig a trench, in a location to be determined by Landlord, so as to
enable Tenant to install conduits connecting telecommunications and data between
Premises A and Premises B. All conduits and connections shall be made, installed
and thereafter maintained by Tenant at Tenant's sole cost. Tenant shall install
equipment, at the sole cost, expense and risk of Tenant, and shall do so in a
good, workmanlike manner and in compliance with all federal, state, and local
building, zoning, electric, telecommunications and safety codes, ordinances,
standards, regulations, laws, and requirements, including, without limitation,
those of the Federal Communications Commission (FCC). Tenant, at its sole cost
and expense, shall obtain any permits, licenses, variances or other approvals
required with respect to the installation or operation of the equipment to be
installed by Tenant or to the alterations to be performed by Tenant. Tenant
shall deliver true and correct copies thereof to Landlord prior to commencing
any installation or alterations.

         9. SECURITY

                  With respect to security for the Building and the parking lot,
Landlord and Tenant hereby agree as follows: Security of the Premises is the
sole responsibility of the Tenant and that the Landlord has no liability for
breach of security to the Premises. Tenant may at Tenant's expense install a
security system to the Premises; provided, however, that Tenant, in addition to
access otherwise required hereunder, will provide Landlord adequate access to
the Premises in case of emergencies particularly regarding Premises that contain
fire sprinkler risers and equipment. All repairs required to the Premises caused
solely as a result of security breaches are the responsibility of the Tenant,
however, Landlord may elect to effect such repairs, if appropriate to insure
continued security, protection of property, or safety of life. The cost of such
repairs shall be Additional Rent.

                  A. TENANT'S RESPONSIBILITY. Tenant shall: (1) abide by all
policies, procedures and rules and regulations for use of the access system, (2)
report promptly the loss or theft of all keys which would permit unauthorized
entrance to the Premises, Building or parking lot, (3) promptly report to
Landlord door-to-door solicitation or other unauthorized activity in the
Building or parking lot, and (4) promptly inform the Landlord's security
contractor in the event of a break-in or other emergency. In addition, Tenant
may, at its option and sole cost and expense, install its own interior security
system pursuant to plans to be submitted to Landlord for

                                    Page 12
<PAGE>   21
Landlord's approval, which approval shall not be unreasonably withheld.

                  B. INTERRUPTION OF SECURITY. Tenant acknowledges that the
above security provisions may be suspended or modified at Landlord's sole
discretion or as a result of causes beyond the reasonable control of Landlord.
No such interruption, discontinuance or modification of security service will
constitute an eviction, constructive eviction, or a disturbance of Tenant's use
and possession of the Premises, and further, no interruption, discontinuance or
modification of security service will render Landlord liable to Tenant or
third-parties for damages, abatement of Rent, or otherwise, or relieve Tenant of
the responsibility of performing Tenant's obligations under this Lease.

                  C. HURRICANE SHUTTERS. Tenant may, at Tenant's sole cost and
expense (which shall include all expenses reasonably incurred by Landlord unless
plans for hurricane shutters were incorporated as part of the initial
construction document review process) install protective hurricane shutters on
the interior of the windows of the Premises. Any such installation of hurricane
shutters shall be subject to the prior approval of the Landlord, which approval
shall not be unreasonably withheld. The hurricane shutters shall be approved by
the Landlord as to size, color, type of shutter, mode of attachment and such
other criteria as Landlord shall from time-to-time determine. The Tenant must

or improvements other than those set forth in the Work Letter attached hereto

feet of any structural column in performing any Alterations. All work shall be
performed by those pre-qualified architects and contractors designated by
Landlord, conditioned upon each of such architects and contractors offering to
Tenant competitive prices in the market place in the absence of which Tenant may
use architects and/or contractors selected by Tenant who shall, however, be

will become Landlord's property when incorporated into or affixed to the
Building. Specifically exempted from Major Alterations, however, shall be
Tenant's trade fixtures and personal property. However, at Landlord's option
Landlord may, at the expiration of the Lease Term, require Tenant, at Tenant's
expense, to remove special use Alterations made by or on behalf of Tenant and to
restore the Premises to their original condition.

                  Prior to the commencement of any Major Alterations by or for
Tenant, Tenant shall furnish to Landlord certificates evidencing the existence
of builder's risk, comprehensive general liability, and worker's compensation
insurance complying with the requirements of Insurance Section of this Lease.
Prior to the commencement of any Alternation, Tenant shall furnish to Landlord a

Alterations shall abide by the Landlord's reasonable job site rules and
regulations and fully cooperate with Landlord's construction representative in
coordinating all of the work in the Building including, without limitation, the
hours of work, parking, and use of the construction elevator.

energy efficiency program offered by the electric service provided to the
Building.

                  All materials used in any Alterations, including, without
limitation, paint, carpet, wall or window coverings, carpet glues, and any other
chemicals shall be subject to Landlord's prior written approval, which approval
shall not be unreasonably withheld or delayed.

                  All Alterations shall be performed in a good and workman like
manner. Tenant shall, prior to the commencement of any Alterations, and if
required by law, obtain and exhibit to Landlord a recorded Notice of
Commencement together with any governmental permit required for the Alterations.
Within ten (10) days after completion of any Alterations, Tenant shall deliver
to Landlord copies of any plans and specifications for such Alterations, in
accordance with CAD storage maintenance standards.

                  B. ALTERATION FEE. Tenant shall pay to Landlord as Additional
Rent (or to its nominee or designated contractor, as Landlord may direct) in
connection with all Major Alterations a fee (the "Alteration Fee") for overhead
and administrative costs in connection with each such Major Alteration, for
Landlord's review and approval of all plans and specifications for such Major
Alteration, for Landlord's construction coordination and monitoring of such
Major Alteration, and for all other reasonable costs and expenses



                                    Page 14
<PAGE>   23
incurred by Landlord as a result of or in connection with each such Major
Alteration, based on a commercially reasonable hourly fee and reasonable and
customary hours expended for each Major Alteration. The Alteration Fee shall be
paid in monthly installments during the course and performance of the Major
Alterations within twenty (20) days from receipt of Landlord's reasonably
detailed invoice. Within twenty (20) days after completion of the Major
Alterations, Tenant shall pay to Landlord the entire balance of the Alteration
Fee if not theretofore paid in full. There shall be excluded from the
computation of the construction cost of each Major Alteration the cost of
furniture, removable furnishings, draperies, office equipment, painting,
carpeting, removable cabinetry, items of special decoration and telephone
installation and engineer's, architects', space planners' and other
professionals' fees. All Major Alterations shall be done in a good and
workmanlike manner. Tenant shall, prior to the commencement of any Alterations,
obtain and exhibit to Landlord any governmental permit required for the
Alterations. The Alteration Fee provided for in this Section B. shall not be
applicable to incurred pursuant to or applicable to the initial build-out of the
Premises or the initial build-out to the Expansion Premises, if applicable,
pursuant specifically to the Work Letter attached hereto and made a part hereof
and pursuant to construction plans initialed by Landlord pursuant to the Work
Letter. All Alterations made by Tenant, other than those herein described as a
Major Alteration, may be undertaken without the prior written consent of
Landlord and shall not be subject to any fees payable to Landlord.

         12. LANDLORD'S ADDITIONS AND ALTERATIONS

         Landlord has the right to make changes in and about the Building and ,
subject to the provisions of Section 7, parking areas (provided, however, that
the number of the reserved parking spaces provided to Tenant shall be otherwise
reasonably relocated and not be lost to Tenant), including, but not limited to,
signs, entrances, address or name of Building. Such changes may include, but not
be limited to, rehabilitation, redecoration, refurbishment and refixturing of
the Building and expansion of or structural changes to the Building. The right
of Tenant to quiet enjoyment and peaceful possession given under the Lease will
not be deemed breached or interfered with by reason of Landlord's actions
pursuant to this paragraph so long as such actions do not materially deprive
Tenant of its use and quiet enjoyment of the Premises. During the Term of this
Lease, and any extensions of the Initial Term, Landlord shall not, without the
written approval of Tenant, which shall not be unreasonably withheld or delayed,
construct a second story upon any single-story portion of the Building in which
Tenant is leasing a minimum of 50,000 square feet.

         13. ASSIGNMENT AND SUBLETTING

                  A. LANDLORD'S CONSENT REQUIRED. Except as provided below,
neither Tenant, nor Tenant's legal representatives or successors-in-interest by
operation of law or otherwise will effect a Transfer (as hereinafter defined)
without first obtaining the consent of Landlord, which consent Landlord shall
not unreasonably withhold provided that all of the requirements of paragraph B.
of this Section 13 are satisfied. As used in this Section 13, any of the
following shall be deemed to be a Transfer: assignment of this Lease, in whole
or in part; sublet of all or any part of the Premises; any license allowing
anyone other than Tenant to use or occupy all or any part of the Premises; a
pledge or encumbrance by mortgage or other instrument of Tenant's interest in
this Lease; or any transfer of partnership interest as described in paragraph D.
of this Section 13, as applicable. Consent by Landlord to any transfer shall not
constitute a waiver of the requirement for such consent to any subsequent
transfer. In lieu of approving any transfer, Landlord may elect to terminate
this Lease as to the portion of the Premises affected by such transfer (together
with such limited additional portion of the Premises needed by Landlord to
render the terminated portion marketable) by giving Tenant notice of such
election, in which event this Lease and the rights and obligations of the
parties hereunder shall cease as of a date set forth in such notice which date
shall not be less than thirty (30) days after the date of such notice. If any
improvements and expenditures are needed to the space so recaptured by Landlord
to separate it from the remaining Premises, Tenant shall pay, or cause
transferee to pay all cost to recapture the space. In the event of any such
termination, all Rent shall be adjusted as of the date of such termination.
Landlord's approval shall not be required for an assignment of this Lease or
sublease of any portion of the Premises to an affiliate (defined as any company
controlling, controlled by or under common control with Tenant) of Tenant and
further provided that the use of the Premises shall be permitted hereunder and
specifically providing that the Guarantor of this Lease shall remain liable
under this Lease and shall deliver to Landlord a re-affirmation of its Guaranty.
Landlord's approval shall likewise not be required in the specific instance of
an assignment of this Lease or sublease of the Premises to a non-affiliate of
Tenant, which has a minimum net worth or value, or member's equity of
$25,000,000.00, and whose use of the Premises shall be permitted hereunder, in
which instance the Guarantor, herein defined, shall thereafter be released from
the Guaranty and interest of the Tenant to any portion of the Expansion Premises
not then under lease to the Tenant shall terminate and be of no further force
and effect. Tenant shall provide Landlord with at least thirty (30) days prior
written notice of an assignment or sublease to an affiliate of Tenant, together
with such financial information as Landlord shall reasonably require to verify
the net worth or value of Tenant and the proposed assignee or sublessee.
Landlord shall not disseminate such financial information, except to its
advisors and Lenders, unless the proposed assignee or sublessee is a publicly
traded company.

                  B. CONDITIONS FOR TRANSFER APPROVAL. The parties recognize
that this Lease and the Premises are unique, and that the nature and character
of the operations within and management of the Premises are important to the
success of the Building. Accordingly,

                                    Page 15
<PAGE>   24

assignees having a net worth of not less than $25,000,000.00), be entitled to
arbitrarily withhold its consent to any transfer, unless all of the following
conditions are satisfied, in which event, Landlord agrees that it shall not
unreasonably withhold its consent to the transfer in question:

worth that is not less than the greater of (i) the net worth that Tenant had on
the Commencement Date; or (ii) the net worth of Tenant immediately prior to the
request of Landlord's consent to the proposed Transfer;

                           (3) The form of the proposed sublease or instrument
of assignment or occupancy shall be reasonably satisfactory to Landlord, and

                           (4) There shall not be more than two (2) occupants
of the Premises; and

                           (5) The proposed subtenant or assignee or occupant

with respect to the space assigned or sublet and Tenant shall provide Landlord
with a copy of such assumption/transfer document;

                           (7) Tenant shall pay to Landlord a transfer fee prior
to the effective date of the transfer in order to reimburse Landlord equal to
all of Landlord's reasonable and verifiable costs and expenses incurred with
respect to the transfer, including, without limitation, costs incurred in
connection with the review of financial materials, meetings with representative
of transferor and/or transferee and preparation, review, approval and execution
of the required transfer documentation.

                           (8) As of the effective date of the transfer and
continuing throughout the remainder of the Term, the Base Rent shall not be less
than the Base Rent set forth in the BLI Rider;

                           (9) Tenant to which the Premises were initially
leased shall continue to remain liable under this Lease for the performance of
all terms, including but not limited to, payment of Rental due under this Lease;

                           (10) Unless the transfer is to a non-affiliate of
Tenant which has a minimum net worth or value or member's equity of
$25,000,000.00 Tenant's guarantor shall continue to remain liable under the
terms of the Guaranty of this Lease and, if Landlord deems it necessary, such

                           (13) The proposed Transfer shall not, in the
Landlord's reasonable judgment cause physical harm to the Building or harm to
the reputation of the Building that would result in an impairment of Landlord's
ability to lease space in the Building or a diminution in the rental value of
the Rentable Space in the Building.

                           (14) The proposed use of the Premises by the

                           (15) The proposed Transfer will not cause a violation
of another lease for space in the Building of give an occupant of the Building a
right to cancel its lease.

         Tenant acknowledges that the foregoing is not intended to be an
exclusive list of the reasons for which Landlord may reasonably withhold its
consent to a proposed Transfer. Tenant, expressly, knowingly and voluntarily
waives any right, claim or remedy otherwise available to Tenant for money
damages (nor shall Tenant claim any money damages by way of set-off,
counterclaim or defense) based on any claim or assertion by Tenant that Landlord
has unreasonably withheld or unreasonably delayed its consent or approval to any
proposed transfer under this Lease.

                                    Page 16
<PAGE>   25

                  C. TRANSFER OF CORPORATE SHARES. If at any time after
execution of this Lease the Tenant shall merge with another corporation or
entity or sell substantially all of the assets or shares to another corporation
or entity, and Tenant is not the surviving entity, Tenant shall deliver to
Landlord a certificate confirming that the surviving entity has a net worth or
value or member's equity as applicable of not less than that of Tenant prior to
such merger. Such certificate shall be delivered within fifteen (15) days after
such has occurred. In no event whatsoever shall any merger or sale of assets by
Tenant constitute an assignment by Tenant which would require Landlord's
approval.

                  D. Unless Tenant complies with Section 13.B., If Tenant shall
transfer its assets to or in other manner change the nature of its entity so as
to be a general limited partnership and if at any time thereafter and if at any
time after execution of this Lease any part or all of the interests in the
capital or profits of such partnership or any voting or other interests therein
shall be transferred by sale, assignment, bequest, inheritance, operation of law
or other disposition (including, but not limited to, such a transfer to or by a
receiver or trustee in federal or state bankruptcy, insolvency or other
proceedings, and also including, but not limited to, any adjustment in such
partnership interests) so as to result in a change in the present control of
said partnership by the person or persons now having control of same, a transfer
shall be deemed to have occurred. Tenant shall give Landlord notice that such
transfer is imminent at least fifteen (15) days prior to the date of such
transfer. If any such transfer is made (and regardless of whether Tenant has
given notice of same), Landlord may elect to terminate this Lease at any time
thereafter by giving Tenant notice of such election, in which event this Lease
and the rights and obligations of the parties hereunder shall cease as of a date
set forth in such notice which date shall be not less than sixty (60) days after
the date of such notice. In the event of any such termination, all Rent (other
than any Additional Rent due Landlord by reason of Tenant's failure to perform
any of its obligations hereunder) shall be adjusted as of the date of such
termination.

                  E. ACCEPTANCE OF RENT FROM TRANSFEREE. The acceptance by
Landlord of the payment of Rent following any assignment or other transfer
prohibited by this Section shall not be deemed to be a consent by Landlord to
any such assignment or other transfer nor shall the same be deemed to be a
waiver of any right or remedy of Landlord hereunder.

                  F. ADDITIONAL PROVISIONS RESPECTING TRANSFERS. Without
limiting Landlord's right to withhold its consent to any Transfer by Tenant, and
regardless of whether Landlord shall have consented to any such Transfer,
neither Tenant nor any other person having an interest in the possession, use or
occupancy of the Premises or any part thereof shall enter into any lease,
sublease, license, concession, assignment or other transfer or agreement for
possession, use or occupancy of all or any portion of the Premises, which
provides for rental or other payment for such use, occupancy or utilization
based, in whole or in part, on the net income or profits derived by any person
or entity from the space so leased, used or occupied, and any such purported
lease, sublease, license, concession, assignment or other transfer or agreement
shall be absolutely void and ineffective as a conveyance of any right or
interest in the possession, use or occupancy of all or any part of the Premises.
Except with respect to payments between affiliates, there shall be no deduction
from the rental payable under any sublease or other Transfer from the amount
thereof passed on to any person or entity, for any expenses or costs related in
any way to the subleasing or Transfer of such space.

                  G. Landlord shall have the right to audit Tenant's books and
records, only with respect to the Premises, to determine the amount payable to
the Landlord under this subsection. All sums payable by Tenant under this
Section shall be payable to Landlord as Additional Rent promptly upon receipt by
Tenant.

                  H. If, this Lease is purported to be assigned, without the
consent of the Landlord, where Landlord's approval or consent is required
hereunder, or the Premises are sublet or occupied by anyone other than Tenant,
where Landlord's approval or consent is required hereunder, Landlord may accept
rents from the assignee, subtenant or occupant and apply the net amount received
to the Rent reserved in this Lease, but no such assignment, subletting,
occupancy or acceptance of Rent shall be deemed a waiver of the requirement for
Landlord's consent as contained in this section or constitute a novation or
otherwise release Tenant from its obligations under this Lease.

                  I. Except as specifically provided herein, the joint and
several liability of Tenant and any immediate and remote successor-in-interest
of Tenant (by assignment or otherwise), and the due performance of the
obligations of this Lease on Tenant's part to be performed or observed shall not
in any way be discharged, released or impaired by any: (i) agreement that
modifies any of the rights or obligations of the parties under this Lease, (ii)
stipulation to extend the time within which an obligation under this Lease is to
be performed, (iii) waiver of the performance of an obligation under this Lease,
or (iv) failure to enforce any of the obligations set forth in this Lease.

                  J. If Landlord shall consent to any Transfer, Tenant shall in
consideration therefor, pay to Landlord as Additional Rent an amount equal to
the Transfer Consideration, or Landlord may elect to recapture the Transferred
portion of the Premises and terminate this Lease with respect to that portion
only. For purposes of this paragraph, the term Transfer Consideration shall mean
in any Lease Year (i) any rents, additional charges or other consideration
payable to Tenant by the transferee of the Transfer which is in excess of the
Base Rent and Overhead Rent accruing during such Lease Year, (ii) all sums paid
for the sale or rental of Tenant's fixtures, leasehold improvements, equipment,
furniture or other personal property in excess of the fair market sale or rental
value thereof as of the date of the Transfer and (iii) all sums paid for
services provided by Tenant to the transferee (including, without limitation,
secretarial, word processing, receptionist, conference rooms, and library) in
excess of the fair




                                    Page 17
<PAGE>   26

market value of such services. Landlord shall have the right to audit Tenant's
books and records upon reasonable notice to determine the amount of Transfer
Consideration payable to Landlord. In the event such audit reveals an
understatement of Transfer Consideration in excess of five percent (5%) of the
actual Transfer Consideration due Landlord, Tenant shall pay for the cost of
such audit within ten (10) days after Landlord's written demand for same and if
such understated amount is Five Percent (5%) or less, Landlord shall pay
Tenant's reasonable expenses in connection therewith.

                  K. Any permitted sublease shall provide: (i) the subtenant
shall comply with all applicable terms and conditions of this Lease to be
performed by Tenant; (ii) the sublease is expressly subject to all of the terms
and provisions of this Lease; and (iii) unless Landlord elects otherwise, the
sublease will not survive the termination of this Lease (whether voluntarily or
involuntarily) or resumption of possession of the Premises by Landlord following
an Event of Default by Tenant. The sublease shall further provide that if
Landlord elects, the sublease shall further survive a termination of this Lease
or resumption of possession of the Premises by Landlord following a default by
Tenant, the subtenant will, at the election of Landlord, attorn to the Landlord
and continue to perform its obligations under its sublease as if this Lease had
not been terminated and the sublease were a direct lease between the Landlord
and subtenant. The sublease shall otherwise be in form and substance reasonably
satisfactory to the Landlord. Any assignment of lease shall contain an
assumption by the Assignee of all terms, covenants and conditions of this Lease
to be performed by the Tenant and shall otherwise be in form and substance
reasonably satisfactory to the Landlord.

                  L. TERMINATION OF EXPANSION RIGHTS. An assignment of this
Lease or a sublease of any portion or all of the Premises to a non-affiliate of
Tenant shall cause the immediate termination and recission of any interest in
the Tenant to the Expansion Premises pursuant to the First Expansion Premises
Option, the Second Expansion Premises Option and the Right of First Refusal all
as contained in Section 1.B. of this Lease.

                  M. Landlord hereby consents to the use of up to 10,000
rentable square feet by Hank Asher or by a business controlled by Hank Asher,
provided same is of a permitted use as described herein.

         14. TENANT'S INSURANCE COVERAGE

                  A. GENERAL. Tenant agrees that, at all times during the Lease
Term (as well as prior and subsequent thereto if Tenant or any of Tenant's
Agents should then use or occupy any portion of the Premises), it will keep in
force, with an insurance company licensed to do business in the State of
Florida, and at least A rated in the most current edition of Best's Insurance

the amount of not less than the amount set forth in the BLI Rider, combined
single limit per occurrence for injury (or death) and damages to property, (ii)
with deductible of not more than Five Hundred Thousand and NO/100 Dollars
($500,000.00), provided, however, that this Lease remains guaranteed by the
Guarantor and further provided that the Tenant continues to have a net worth or
value or member's equity, as applicable, of not less than $25,000,000.00, in the
absence of either of which requirements the deductible shall be in excess of
Fifty Thousand and NO/100 Dollars ($50,000.00) insurance on an "All Risk or
Physical Loss" basis, including sprinkler leakage, vandalism, malicious
mischief, fire and extended coverage, covering all improvements to the Premises,
fixtures, furnishings, removable floor coverings, equipment, signs and all other
decoration or stock in trade, in the amounts of not less than the full
replacement value thereof, and (iii) worker's compensation and employer's
liability insurance, if required by statute. Such policies will: (i) include
Landlord and such other parties as Landlord may reasonably designate as
additional insured's with respect to commercial general liability coverages
only, (ii) be considered primary insurance, (iii) include within the terms of
the policy or by contractual liability endorsement coverage insuring Tenant's
indemnity obligations under paragraph 19, and (v) provide that it may not be
canceled or changed without at least thirty (30) days prior written notice,
except in the event of a non-payment of premium(s) in which instance ten (10)
days written notice shall be required from the company providing such insurance
to each party insured thereunder. Tenant will also maintain throughout the Lease
Term worker's compensation insurance in accordance with applicable law.

                  B. EVIDENCE. The insurance coverages to be provided by Tenant
will be for a period of not less than one year. At least thirty (30) days prior
to the Commencement Date, Tenant will deliver to Landlord original certificates
of all such paid-up insurance; thereafter, at least thirty (30) days prior to
the expiration of any policy Tenant will deliver to Landlord such original
certificates as will evidence a paid-up renewal or new policy to take the place
of the one expiring. Any insurance required of Tenant under this Lease may be
furnished by Tenant under an umbrella or blanket policy carried by Tenant. Such
umbrella or blanket policy shall contain an endorsement that names Landlord as
an additional insured, references the Premises, and guarantees a minimum limit
available for the Premises equal to the insurance amounts required in the Lease.

         15. LANDLORD'S INSURANCE COVERAGE

                  A. GENERAL. Landlord will at all times during the Lease Term
maintain a policy or policies




                                    Page 18
<PAGE>   27
of insurance with an insurer authorized to do business in the State of Florida
and rated A or better, by Best Rating Service, insuring the Building against
loss or damage by fire, explosion or other hazards and contingencies typically
covered by insurance for an amount of not less than Fifty Million and NO/100
Dollars ($50,000,000.00).

                  B. TENANT'S ACTS. Tenant will not do or permit anything to be
done upon or bring or keep or permit anything to be brought or kept upon the
Premises which will increase Landlord's rate of insurance on the Building. If by
reason of the failure of Tenant to comply with the terms of this Lease, or by
reason of Tenant's occupancy (even though permitted or contemplated by this
Lease), the insurance rate shall at any time be higher than it would otherwise
be, Tenant will reimburse Landlord for that part of all insurance premiums
charged because of such violation or occupancy by Tenant. Tenant agrees to
comply with any reasonable requests or recommendation made by Landlord's
insurance underwriter inspectors.

         16. WAIVER OF RIGHT OF RECOVERY

                  A. GENERAL. Except as provided in Section 39, neither Landlord
nor Tenant shall be liable to the other for any damage to any building,
structure or other tangible property, or any resulting loss of income, or losses
under worker's compensation laws and benefits, even though such loss or damage
might have been occasioned by the negligence of such party, its agents or
employees. The provisions of this Section shall not limit the indemnification
for liability to third parties pursuant to Section 19. As used in this Section
16.A., "damage" refers to any loss, destruction or other damage.

                  B. EXCLUSIONS. Tenant acknowledges that Landlord will not
carry insurance on tenant improvements, furniture, furnishings, trade fixtures,
equipment installed in or made to the Premises by or for Tenant, in accordance
with the Work Letter attached hereto, and Tenant agrees that Tenant, and not
Landlord, will be obligated to promptly repair any damage thereto or replace the
same.

         17. DAMAGE OR DESTRUCTION BY CASUALTY

         A. MINOR CASUALTY. In the event that at any time after the
Commencement Date all or any portion of the Building or the Premises is damaged
by fire or other casualty; and as a result of such damage to the Building or
Premises, Tenant loses the use and quiet enjoyment of a portion or portions of
the Premises which, in the aggregate, are equal to or less than Thirty Percent
(30%) of the rentable square feet of the Premises, and/or the use and quiet
enjoyment of Thirty Percent (30%) or less of the parking spaces allocated to the
Premises and/or the loss of Thirty Percent (30%) of major services to the
Premises (i.e., utilities, air-conditioning and the like) Landlord will have the
option of (i) terminating this Lease, or any renewal thereof, by serving notice
upon Tenant within sixty (60) days in the event that the damage is incurred
during the last two (2) years of the Initial Term or during any then current
Renewal Term, or (ii) terminating this Lease if Landlord determines, using
reasonable commercial judgment, that it cannot restore the Premises, the parking
lot or major services within three hundred sixty five (365) days and/or there is
a lack of adequate insurance proceeds, provided Landlord maintains the insurance
required hereunder, to rebuild and/or restore, or (iii) alternatively, if
Landlord determines, using commercially reasonable judgment that the Premises,
parking lot and/or major services, as applicable, can be completed or restored
within three hundred sixty five (365) days from the date of the casualty,
Landlord shall, to the extent of available insurance proceeds, diligently pursue
to completion and/or restoration, as applicable, the Premises, the parking lot
and/or major services in a manner so as to render same substantially the same
size, design, quality, construction and, as applicable to the major services,
the level of said services, as existed immediately prior to the date of the
damage (except for Tenant's personal property, furniture, furnishings, equipment
[the Tenant's Work anticipated by the Work Letter attached hereto] and trade
fixtures (collectively "Tenant's Property")) the repair and restoration of which
shall be promptly performed by and at the expense of Tenant. While Landlord
proceeds to restore the Premises, parking lot and/or major services, as
applicable, the Tenant may continue to peacefully use and occupy that portion of
the Premises which remain safe to occupy and Tenant shall receive a
proportionate abatement of Base Rent proportionate to the extent of the loss of
the Premises, parking lot or major services unavailable to Tenant until
completion. In the event that the repair and restoration has not been completed
by Landlord on the date three hundred sixty five (365) days from the date the
casualty, such that Tenant may peaceably use and occupy the entire Premises with
full use of major services, then Tenant shall have the option to terminate this
Lease by notice to Landlord given not later than thirty (30) days following such
date.

         B. MAJOR CASUALTY. In the event that at any time after the
Commencement Date all or any portion of the Building or Premises is damaged by
fire or other casualty, and as a result of such damage to the Premises, Tenant
loses the use and quiet enjoyment of a portion or portions of the Premises,
which in the aggregate exceed Thirty Percent (30% ) of the rentable square feet
of the Premises and/or the use and quiet enjoyment of more than Thirty Percent
(30%) of the parking spaces allocated to the Premises and/or more than Thirty
Percent (30%) of major services to the Premises (i.e., utilities,
air-conditioning and the like), Landlord may, so long as it treats Tenant, and
similarly situated tenants, in a nondiscriminatory manner, either: (a) terminate
this Lease upon serving written notice upon Tenant within sixty (60) days of the
date of destruction or (b) elect to restore the Premises unless Tenant elects in
its sole discretion to terminate this Lease by serving written notice upon
Landlord within sixty (60) days of the date of destruction. Should Landlord
elect to restore the Premises, in the absence of a timely notice of termination
by Tenant, then, Landlord shall diligently pursue to completion the repair

                                    Page 19
<PAGE>   28
and restoration of the Premises, parking lot and/or major services as a complete
architectural unit of substantially the same size, design, quality and
construction as existed immediately prior to the date of damage and level of
major services (except for Tenant's Property, the repair and restoration of
which shall be promptly performed by and at the expense of Tenant). During the
course of repairs of the Premises, parking lot and/or the major services, the
Tenant may, as allowed by applicable law and not a hindrance to the repair
and/or reconstruction: (a) continue to occupy such portion of the Premises as is
usable in which instance the Rent payable by Tenant to Landlord shall abate
proportionately or (b) Landlord may, at its option, provide to Tenant temporary
substitute space reasonably acceptable to Tenant, in an amount approximating the
space damaged in the Premises, in either the Building or in an office building
which is of a quality reasonably comparable to the Building and is at a location
reasonably proximate to the Building, having parking spaces proximately adjacent
thereto and in amount approximately equal to 3.0 spaces per 1,000 square feet of
damaged rentable square feet in the Building or, if only the parking spaces
allocated to the Premises are damaged and there is no damage to the Building as
a result of which Tenant loses the use and quiet enjoyment of any portion of the
Premises, then Landlord may, at its sole option, provide temporary substitute
parking space in a location reasonably proximate to the Premises, and in an
amount approximately equal to the number of parking spaces damaged. In the event
that during restoration Landlord elects to provide Tenant with substitute space,
the Rent for the substitute space shall be as otherwise payable under the Lease.
However, should Landlord not elect to provide such substitute office or parking
space, the Tenant may vacate not less than all of the Premises in which instance
the Rent for the Premises, otherwise payable by Tenant to Landlord, will abate
until such time as the Premises, the parking lot and/or major services shall
have been restored. In the event either Landlord or Tenant has terminated this
Lease and that the Landlord shall not have elected to provide Tenant with
substitute parking or substitute Premises, in the absence of a termination of
this Lease by Tenant, and/or substitute parking, Tenant shall be solely
responsible for any and all costs attendant to Tenant's lease of substitute
premises or parking spaces.

         In the event the repair and restoration required by Section 17.B. has
not been or cannot reasonably be completed such that Tenant may peacefully use
and occupy the entire Premises on the date three hundred sixty-five (365) days
from the date of the casualty, subject to extension for FORCE MAJEURE, then,
commencing on such date, Tenant shall have the option to terminate this Lease by
notice to Landlord given no later than thirty (30) days following such date or
the date on which it is determined the Premises cannot reasonably be completed
as provided for in this Paragraph. Notwithstanding the preceding sentence,
without regard to extension for FORCE MAJEURE, in the event such repair and
restoration has not been completed by Landlord such that Tenant may peacefully
use and occupy the entire Premises eighteen (18) months from the date of
casualty, then Tenant shall have the option to terminate this Lease by notice to
Landlord given no later than fifteen (15) days following such date.

         C. CONTINUATION OF LEASE. In the event this Lease is not terminated as
above provided, this Lease shall not terminate and Landlord shall restore and
repair all such damage as set forth in this Section 17.

         D. ABATEMENT OF RENT. Tenant shall be entitled to a proportionate
abatement of the Rent payable during the period commencing on the date of the
casualty and ending (i) on the date the damaged portion of the Premises is
repaired as set forth in this Section 17, if the Lease is not terminated as
herein provided, or (ii) on the date of the casualty, if it is so terminated.
For purposes of this Section, Rent, shall be abated in proportion to the area of
the Premises which Tenant cannot reasonably use and quietly enjoy as this Lease
intended during such period. Landlord shall receive one hundred percent (100%)
of the rental loss insurance , if any, payable with regard to any such casualty.

         E. DAMAGE OR DESTRUCTION OF THE PREMISES PRIOR TO THE COMMENCEMENT
DATE. Prior to the Commencement Date, Landlord shall insure the Premises against
loss or damage.

                  18. CONDEMNATION AND EMINENT DOMAIN

         A. EMINENT DOMAIN. As used herein, the term "Taking" means any taking
of the Premises, or the parking spaces allocated to the Premises, or any part
thereof, in or by condemnation or other eminent domain proceeding as evidenced
by a final judgment or non-appealable order pursuant to any law, general or
special, sale in lieu of condemnation, or by reason of the temporary requisition
of the use or occupancy thereof, by any and all federal, state, regional,
county, municipal or local government, or any department, commission, board,
bureau, agency or office thereof ("Governmental Authority") having or claiming
jurisdiction over all of any part of the Building or the Project (including,
without limitation, the Premises) or the use thereof.

         B. TERMINATION RIGHT. In the event of a Taking (i) of a portion or
portions of the Premises which, in the aggregate, exceeds thirty percent (30%)
of the rentable square feet of the Premises, or (ii) any portion of the Premises
whereby Tenant loses the use and quiet enjoyment of more than thirty percent
(30%) of the parking spaces allocated to the Premises (unless Landlord shall
provide to Tenant on a timely basis, at no cost to Tenant, substitute space
reasonably acceptable to Tenant in an amount approximating the space in the
Premises taken by the Taking and in an office building which is of a quality
reasonably comparable to the Building, and parking space adjacent to such
building in an amount approximately equal to 3.0 spaces per 1000 square feet of
rentable square feet of the Premises taken by the Taking, or if only parking
area is taken by the Taking and the Taking does not result in the loss of the
use and quiet enjoyment of any portion of the Premises, then parking
                     
                                     Page 20
<PAGE>   29
spaces approximately equal to the amount taken by the Taking, in any of such
events in a Location Reasonably Proximate to the Premises), Landlord or Tenant
may terminate this Lease by written notice to the other given within (30)
business days of any such Taking. In the event of termination of this Lease as
hereinabove provided, this Lease shall expire on the effective date of such
Taking, with the same force and effect as if that date were the date herein set
forth for the expiration of the Term of this Lease, and Tenant's obligation to
pay Base Rent, Overhead Rent, Additional Rent and all other obligations of
Tenant shall be apportioned as of such date. In the event that, in the absence
of a termination of this Lease by either party, Landlord provides Tenant with
substitute space and/or substitute parking as provided above, then Landlord
shall be responsible for and shall pay or reimburse Tenant, promptly upon
written demand, for any and all reasonable direct costs and expenses incurred by
Tenant relative to such substitute parking and such substitute space, including
without limitation, moving and transportation expenses, and any and all fees and
commissions payable to real estate brokers, if any. Tenant shall pay to Landlord
as a contribution to the cost of such substitute space, an amount equal to the
lesser of (i) the actual rental required to be paid for such substitute space,
or (ii) the Rent that has been abated with respect to the Premises taken.

         C. CONTINUATION OF LEASE . If there is a Taking of the Premises, or
some portion thereof, and this Lease is not terminated as to the entire Premises
as provided in Section 18(B), then this Lease shall continue in full force and
effect as to such part not taken, provided that, effective as of the date of the
Taking (or the taking of actual possession by the Governmental Authority, if
earlier), the Base Rent, Overhead Rent, Additional Rent and all other
obligations of Tenant shall be proportionately abated, and Landlord shall
promptly after any such Taking, subject to Section 18(D) below, repair, restore
and rebuild the Building, the parking spaces allocated to the Premises and/or
the Premises, as the case may be, as nearly as is commercially reasonable and
possible to their condition and character immediately prior to such Taking.

                  In the event there is a Taking, which, is less than or equal
to Thirty Percent (30%) of the rentable square feet of the Premises or less than
or equal to Thirty Percent (30%) of the parking spaces allocated to the Premises
or Thirty Percent (30%) of the major services to the Premises (i.e., utilities,
air-conditioning and the like), then Landlord shall use commercially reasonable
efforts to provide to Tenant, on a timely basis, substitute space reasonably
acceptable to Tenant in an amount approximating the space in the Premises taken
by the Taking (in the Building or an office building which is of a quality
reasonably comparable to the Building and is at a Location Reasonably Proximate
to the Premises), and Landlord shall provide parking space adjacent to such
building in an amount approximately equal to 3.0 spaces per 1000 square feet of
rentable square feet of the Premises taken by the Taking or, if only the parking
spaces allocated to the Premises is taken by the Taking and the Taking does not
result in the loss of the use and quiet enjoyment of any portion of the
Premises, the Landlord shall provide substitute parking space in a Location
Reasonably Proximate to the Premises in an amount approximately equal to the
number of parking spaces taken by the Taking. With regard to such substitute
parking and such substitute space, Landlord shall be responsible for and shall
pay or reimburse Tenant, promptly upon written demand, for any and all direct
costs and expenses incurred by Tenant relative to such substitute parking and
such substitute space, including without limitation, moving and transportation
expenses, and any and all fees and commissions payable to real estate brokers,
if any. In the event Landlord does not obtain, within thirty (30) days from the
date of such Taking, such substitute space and/or substitute parking, then
Tenant may, at Tenant's sole option, either (i) terminate this Lease by notice
to Landlord given no later than sixty (60) days after such Taking or (ii) seek
to locate substitute space and/or substitute parking, failing which Tenant may,
at Tenant's sole option, terminate this Lease by notice to Landlord given no
later than ninety (90) days from the date of such Taking. Tenant shall pay to
Landlord as a contribution to the cost of such substitute space, an amount equal
to the Rent that has been abated with respect to the portion of the Premises
which has been the subject of Taking.

         D. ADDITIONAL TERMINATION RIGHTS. If, at the time of any Taking of a
portion or portions of the Building which, in the aggregate, constitute more
than thirty percent (30%) of the rentable square feet of the Premises or the use
and quiet enjoyment of more than thirty percent (30%) parking spaces allocated
to the Premises and less than two (2) years shall remain in the initial Term or
any then current Renewal Term, then either Tenant or Landlord upon notice to the
other party given within thirty (30) business days of any such Taking, may
terminate this Lease. In the event of termination of this Lease as hereinabove
provided, this Lease shall expire with the same force and effect as if that date
were the date herein set forth for the expiration of the Term of this Lease, and
Tenant's obligation to pay Base Rent, Overhead Rent, Additional Rent and all
other obligations of Tenant shall be apportioned as of such date.

         19. LIMITATION OF LANDLORD'S LIABILITY; INDEMNIFICATION

                  A. PERSONAL PROPERTY. All personal property placed or moved
into the Building will be at the sole risk of Tenant or other owner. Landlord
will not be liable to Tenant or others for any damage to person or property
arising from environmental concerns, as hereafter defined, theft, vandalism,
air-conditioning malfunction, the bursting or leaking of water pipes, any act or
omission of any other tenant or occupant of the Building or of any other person,
or otherwise.

                  B. LIMITATIONS. Notwithstanding any contrary provision of this
Lease: Tenant will look solely (to the extent insurance coverage is not
applicable or

                                    Page 21
<PAGE>   30
available) to the interest of Landlord (or its successor as Landlord hereunder)
in the Premises for the satisfaction of any judgment or other judicial process
requiring the payment of money as a result of any negligence or breach of this
Lease by Landlord or its successor or of Landlord's managing agent (including
any beneficial owners, partners, corporations and/or others affiliated or in any
way related to Landlord or such successor or managing agent) and Landlord has no
personal liability hereunder of any kind, and (ii) Tenant's sole right and
remedy in any action or proceeding concerning Landlord's reasonableness (where
the same is required under this Lease) will be an action for declaratory
judgment and/or specific performance.

                  C. INDEMNITY. Tenant agrees to indemnify, defend and hold
harmless Landlord and its agents from and against all claims, causes of actions,
liabilities, judgments, damages, losses, costs and expenses, including
reasonable attorneys' fees and costs, including appellate proceedings and
bankruptcy proceedings, incurred or suffered by Landlord and arising from or in
any way connected with (i) the use, operation, maintenance, and/or repair of the
Premises by Tenant or Tenant's agents, (ii) the acts, omissions of Tenant or
Tenant's agents, (iii) the breach of Tenant's obligation under this Lease, and
(iv) any death, personal injury or property damage occurring in the Premises.
Notwithstanding the foregoing, Tenant's indemnity obligations under this Section
19.C. shall not apply to the extent that any of the foregoing claims, causes of
action, liabilities, judgments, damages, costs and expenses are the result of
the gross negligence or willful misconduct of Landlord and/or Landlord's agents.

         Tenant will reimburse Landlord upon request for all costs incurred by
Landlord in the interpretation and enforcement of any provisions of this Lease
and/or the collection of any sums due to Landlord under this Lease, including
collection of agency fees, and reasonable attorneys' fees and costs, regardless
of whether litigation is commenced, and through all appellate actions and
proceedings, including bankruptcy proceedings, if litigation is commenced. The
foregoing claims, causes of actions, liabilities, judgments, damages, losses,
costs and expenses shall include but not be limited to any of same arising from
Tenant's failure to comply with any of the requirements of Americans with
Disabilities Act ("ADA") or Florida Accessibility Code ("FAC") within the
Premises. Notwithstanding the foregoing, however, Landlord shall not be exempt
from culpability for damage to person or property arising solely from the gross
negligence or willful misconduct of Landlord or Landlord's agents.

         20. Intentionally omitted.

         21. COMPLIANCE WITH LAWS AND PROCEDURES

                  A. COMPLIANCE. Except as provided in Section 39.H.(2), Tenant,
at its sole cost, will promptly comply with all applicable laws, guidelines,
rules, regulations and requirements, whether of federal, state, or local origin,
applicable to the Premises, including, but not limited to, the Americans with
Disabilities Act, 42 U.S.C. section 12101 et seq, the FAC, and those for the
correction, prevention and abatement of nuisance, unsafe conditions, or other
grievances arising from or pertaining to Tenant's use or occupancy of the
Premises. With respect to items which are capitalized related to complying with
the requirements of this Section 21.A., which pertain to capital items, the
portion of the costs thereof attributable to the Lease Term shall be paid by
Tenant (amortized, with interest at the rate of Ten Percent (10%) per annum,
over the lesser of (a) the balance of the Lease (but in no event longer than ten
(10) years), or (b) the useful life of the asset per GAAP); provided, however,
that if the balance of the term of the Lease is less than five (5) years the
amortization shall be over the shorter of the useful life of the item, in
accordance with GAAP or five (5) years, unless, however, the Lease is
subsequently renewed in which event the amortization shall be recalculated
during the renewal period on a pro-rata basis with interest on all amortized
periods at the rate of Ten Percent (10%) per annum. With respect to non-capital
costs (i.e., those items not covered by the immediately preceding sentence),
subject to and conditioned upon Tenant paying, as Operating Expenses to the
extent required under this Lease, Landlord's costs and expenses incurred in
connection therewith. Landlord agrees to comply with all applicable laws,
guidelines, rules, regulations and requirements of governmental authority
affecting the Premises or the Building. Tenant acknowledges that (i) the
Premises and the parking facilities may contain potentially hazardous
substances, including, but not limited to, asbestos containing materials, radon
gas, mineral fibers, and other like materials as set forth in the Law
Engineering Building Phase I Report provided to Tenant (all of such materials
are referred to herein as "Environmental Concerns") and (ii) Tenant has been
advised that the Building does contain asbestos containing materials.
Accordingly, Tenant agrees that Tenant and Tenant's Agents shall comply with all
operation and maintenance programs and guidelines implemented or promulgated
from time to time by Landlord or its consultants, including, but not limited to,
those matters set forth in subsections B and C below, in order to reduce the
risk to Tenant, Tenant's Agents or any other tenants of the Building of injury
from Environmental Concerns. Tenant at its sole cost and expense shall be solely
responsible for taking any and all measures which are required to comply with
the requirements of the ADA and the FAC within the Premises. Any Alterations to
the Premises made by or on behalf of Tenant for the purpose of complying with
the ADA and FAC or which otherwise require compliance with the ADA and FAC shall
be done in accordance with this Lease; provided, that Landlord's consent to such
Alterations shall not constitute either Landlord's assumption, in whole or in
part, of Tenant's responsibility for compliance with the ADA and FAC, or
representation or confirmation by Landlord that such Alterations comply with the
provisions of the ADA and FAC.

                  B. NOTICE PRIOR TO WORK. Except as provided in Section 11,
Tenant shall provide thirty (30)

                                    Page 22
<PAGE>   31
days notice to Landlord prior to the performance by Tenant, Tenant's Agents or
contractors of any repairs, renovation and/or major structural or mechanical
systems maintenance, to the Premises. Such notice shall include a detailed
description of the work contemplated. Tenant shall not perform, or cause to be
performed, any such repair, renovation and/or maintenance without the written
consent of Landlord, and, if such consent is granted, the repair, renovation
and/or maintenance must be performed in accordance with the terms of Landlord's
consent.

                  C. INDEMNIFICATION. Tenant shall indemnify, defend with
counsel chosen by Landlord, and hold harmless Landlord from and against any and
all claims or liability arising from the performance of the repair, renovation,
and/or maintenance described above. This indemnity shall include, but not be
limited to, claims or liabilities asserted against Landlord based upon
negligence, strict liability or other liability by operation of law to any third
party or government entity, and all costs, attorney's fees, expenses, and
liabilities incurred in the defense of any such claim. Furthermore, as a
material part of the consideration to Landlord for the entering into of this
Lease, Tenant assumes all risk of damages to property or injury to persons in,
upon, or about the Premises arising from any act or omission of Tenant, Tenant's
Agents, employees, contractors, and invitees, or causing nonfriable asbestos to
become friable. Tenant agrees to bear the expense of whatever preventive or
abatement measures are required by law and prudent construction practices with
respect to friable asbestos or any other material. Further, Tenant shall be
liable for the entire cost of abating and remediating any such release and
Tenant shall indemnify, defend, and hold harmless Landlord from and against any
and all claims or liability arising therefrom.

         22. RIGHT OF ENTRY

                  Landlord and its agents will have the right to enter the
Premises during all reasonable hours to make necessary repairs to the Premises.
In the event of an emergency, Landlord or its agents may enter the Premises at
any time, without notice, to appraise and correct the emergency condition. Said
right of entry will, after reasonable notice, likewise exist for the purpose of
removing placards, signs, fixtures, alterations, or additions which do not
conform to this Lease. Landlord or its agents will have the right to exhibit the
Premises at any time to prospective tenants within one hundred and eighty days
(180) before the Expiration Date of the Lease. Landlord shall, with respect to
Landlord's rights provided in this Section 22, at all times utilize all
reasonable efforts not to interfere in any material respect with Tenant's use
and occupancy of the Premises.

         23. DEFAULT

                  A. EVENTS OF DEFAULT BY TENANT. The following shall, upon the
giving of notice to Tenant of the nature of the default and the expiration of
any applicable grace period afforded Tenant hereunder as set forth in Section
23.B. constitute an Event of Default under this Lease. If (1) Tenant fails to
make any payment of Rent when due (a "Monetary Default"); or (2) Tenant fails to
fulfill any of the terms or conditions, covenants, agreements or any rules and
regulations attached to this Lease, as Exhibit "C" or promulgated by Landlord
under this Lease which shall in all instances be reasonable and have as close to
equal application to all Tenants of the Building as is practicable (a
"Non-monetary Default"); or (3) the appointment of a trustee or a receiver to
take possession of all or substantially all of Tenant's assets occurs, and such
appointment is not dismissed within thirty (30) days after appointment, or if
the attachment, execution or other judicial seizure of all or substantially all
of Tenant's assets located at the Premises, or of Tenant's interest in this
Lease, occurs; or (4) Tenant or any of its successors or assigns or any
guarantor of this Lease ("Guarantor") should file any voluntary petition in
bankruptcy, reorganization or arrangement, or an assignment for the benefit of
creditors or for similar relief under any present or future statute, law or
regulation relating to relief of debtors; or (5) Tenant or any of its successors
or assigns or any Guarantor should be adjudicated bankrupt or have an
involuntary petition in bankruptcy, reorganization or arrangement filed against
it and such proceeding is not dismissed within thirty (30) days of filing; or
(6) Tenant, before the expiration of the Lease Term and without the prior
written consent of Landlord, vacates the Premises or abandons possession of the
Premises, and fails to pay Rent on a timely basis; or (7) Tenant shall permit,
allow or suffer to exist any lien by or through Tenant, judgment, writ,
assessment, charge, attachment or execution upon Landlord's or Tenant's interest
in this Lease or to the Premises, and/or the fixtures, improvements and
furnishings located thereon, whether claimant or holder thereof has acquired its
right by or through Tenant, unless such lien, judgment, writ, assessment,
charge, attachment or execution is discharged of record or transferred from the
Property by bond within ten (10) days following notice to Tenant; or (8) Tenant,
if a publicly held company, shall cease to conform with minimum listing
requirements of the National Stock Exchange on which it is listed or shall fail
to timely file its 10K statement or otherwise fail to maintain financial
statements required of a publicly traded and listed company, then Tenant shall
be in default hereunder; or (9) if Tenant is not a publicly held company and
neither Tenant nor Guarantor maintains a net worth of at least $25,000,000.00.

                  B. GRACE PERIOD. Notwithstanding anything contained in this
Lease to the contrary, Tenant shall have (i) a period of three (3) business days
after notice from Landlord of a Monetary Default with respect to payment of
Rent; (ii) a period of ten (10) days after notice from Landlord of a Monetary
Default , other than as to payment of Rent; and (iii) a period of twenty (20)
days after notice from Landlord of a Non-Monetary Default in which to cure the
Event of Default. In addition, provided that the Event of Default does not
involve an emergency that must be addressed in a shorter time frame, the grace
period for Non-Monetary Defaults shall be extended for such time as is
reasonably necessary to complete such cure if the Event of Default is of a
nature that it cannot be completely cured within the twenty (20)

                                    Page 23
<PAGE>   32

day period solely as a result of nonfinancial circumstances outside of Tenant's
control, provided that Tenant has promptly commenced all appropriate actions to
cure the default after notice and those actions are thereafter diligently and
continuously pursued by Tenant in good faith. However, if the Non-Monetary
Default is not cured prior to a maximum of sixty (60) days from the date of the
notice of the Non-Monetary Default, then Landlord may pursue all of its
remedies. The notice of a Non-Monetary Default to be given under this subsection
may be combined with the notice required under Section 83.20(3), Florida
Statutes or any successor statute and this Lease shall not be construed to
require Landlord to give two separate notices to Tenant before proceeding with
any remedies.

                  C. REPEATED LATE PAYMENT. Regardless of the number of times of
Landlord's prior acceptance of late payments and/or late charges, (i) if
Landlord notifies Tenant four (4) times in any 12-month period that Rent has not
been paid when due, then any other late payment within such 12-month period
shall automatically constitute a default hereunder and (ii) the mere acceptance
by Landlord of late payments of Rent in the past shall not, regardless of any
applicable laws to the contrary, thereafter be deemed to waive Landlord's right
to strictly enforce this Lease, including Tenant's obligation to make payment of
Rent on the exact day same is due, against Tenant.

                  D. LANDLORD'S DEFAULT. If Tenant asserts that Landlord has
failed to meet any of its obligations under this Lease, Tenant shall provide
written notice ("Notice of Default") to Landlord except in the event of an
Emergency, specifying the alleged failure to perform, and Tenant shall send by
certified mail, return receipt requested, a copy of such Notice of Default to
any and all mortgage holders, provided that Tenant has been previously advised
of the address(es) of such mortgage holder(s). Landlord shall have a thirty (30)
day period after receipt of the Notice of Default in which to commence curing
any non-performance by Landlord, which cure shall have been completed within
sixty (60) days after notice. However, if the Event of Default is of the nature
that cannot be completely cured within the sixty (60) day period, and so long as
Landlord's cure efforts are diligent and continuous then Landlord shall have up
to a maximum of ninety (90) days from the date of notice of the Non-Monetary
Default to cure the Event of Default. If the Non-Monetary Default is not cured
on or before the ninetieth day from the notice of the Event of Default then
Tenant may pursue all of its remedies.

         24. LANDLORD'S REMEDIES FOR TENANT'S DEFAULT

                  A. LANDLORD'S OPTIONS. If there is an Event of Default by
Tenant under this Lease, Landlord may, terminate Tenant's rights in any
Expansion Premises regardless of the prior exercise of same by Tenant pursuant
to the terms of Section 1.B., of this Lease, and, at its option, in addition to
such other remedies as may be available under Florida law:

                           (1)  terminate this Lease and Tenant's right of
possession by notice to Tenant; or


<PAGE>   33
                           (2) terminate Tenant's right to possession but not
the Lease and/or proceed in accordance with any and all provisions of paragraph
B below.

                  B. LANDLORD'S REMEDIES. If there is an Event of Default by
Tenant under this Lease, in addition to all other remedies available to Landlord
at law or in equity, Landlord may:

                           (1) Terminate this Lease by notice to Tenant and
retake possession of the Premises;

(2) Terminate Tenant's right of possession by notice to Tenant without
terminating this Lease and retaking possession of the Premises and relet the
Premises or any part of the Premises in the name of Landlord, or otherwise, as
Tenant's agent, for a term shorter or longer than the balance of the Lease Term,
and may grant concessions or free rent to the new tenant, thereby terminating
Tenant's tenancy in the Premises and right to possess the Premises, without
terminating Tenant's obligations to pay (a) the entire balance of all forms of
Base Rent and Additional Rent for the remainder of the Lease Term, plus (b) the
Reletting Expenses, and (c) the unamortized balance of any brokerage commissions
paid by Landlord in connection with this Lease, any allowances granted to Tenant
under this Lease, and the cost of any Tenant Improvements made by Landlord.
Landlord shall have no obligation to relet the Premises, and its failure to do
so, or failure to collect rent on reletting, shall not affect Tenant's liability
under this Lease. Landlord shall not, in any event, be required to pay Tenant
any surplus of any sums received by Landlord on a reletting of the Premises in
excess of the rent provided in this Lease. If Landlord decides to relet the
Premises or a duty to relet is imposed by law, Landlord shall only be required
to use commercially reasonable efforts to relet the Premises. Commercially
reasonable efforts shall not require Landlord to: (i) use any greater efforts
than Landlord then uses to lease other properties Landlord or its affiliates
owns or manages; (ii) relet the Premises in preference to any other space in the
Building; (iii) relet the Premises to any party that Landlord could reasonably
reject as a transferee under the Assignment or Subletting section of this Lease;
(iv) accept rent in an amount which is less than the fair market rental for the
Premises; (v) perform any tenant improvements, grant any tenant improvement
allowances, grant any "free rent," or otherwise pay any sums or grant any
monetary concessions in order to obtain a new tenant; (vi) observe any
instruction given by Tenant about the reletting process or accept any tenant
offered by Tenant unless the offered tenant leases the entire Premises and the
criteria of this subsection are otherwise fully met. Any entry or reentry by
Landlord, whether had or taken under summary proceedings or otherwise, shall not
absolve or discharge Tenant from liability under this Lease. "Reenter" and
"re-entry" as used in this Lease are not restricted to their technical legal
meaning. No reentry or taking possession of the Premises by Landlord shall be
construed as an election on Landlord's part to accept a surrender of the
Premises unless a notice of such intention is given to Tenant;

                           (3) Stand by and do nothing, and hold Tenant liable
for all Base Rent and additional rent payable under this Lease through the
remainder of the Lease Term;

                           (4) Institute any action as provided by law; 

                           (5) Obtain injunctive and declaratory relief,
temporary or permanent, or both, against Tenant or any acts, conduct or
omissions of Tenant, and further to obtain specific performance of any term,
covenant, or condition of this Lease; 

                           (6) After regaining possession of the Premises,
remove all or any part of Tenant's Property from the Premises and any property
removed may be stored at the cost of, and for the account of, Tenant, and
Landlord shall not be responsible for the care or safekeeping of Tenant's
Property whether in transport, storage, or otherwise, and Tenant waives any and
all claims against Landlord for loss, destruction, damage or injury that may be
occasioned by any acts taken by Landlord under this subsection. Landlord may
retain possession of Tenant's Property until all storage charges and all other
amounts owed by Tenant to Landlord under this Section 23 have been paid in full.
Nothing set forth in this subsection shall limit Landlord's rights to enforce
any lien or security interest in favor of Landlord against Tenant's Property or
Landlord's rights under the End of Term section of this Lease; and

                           (7) If all or any part of the Premises is then
assigned, sublet, transferred, or occupied by someone other than Tenant,
Landlord, at its option, may collect directly from the assignee, subtenant,
transferee, or occupant all rent becoming due to Tenant by reason of the
assignment, sublease, transfer, or occupancy. Any collection directly by
Landlord from the assignee, subtenant, transferee, or occupant shall not be
construed to constitute a novation or a release of Tenant from the further
performance of its obligations under this Lease.

                  C. ACCELERATION. If Landlord exercises the remedies provided
in Subsections (2), (3) or (4) above, Landlord may declare the entire balance of
all forms of rent due under this Lease for the remainder of the Lease Term to be
forthwith due and payable and may collect the then present value of the rents
(calculated using a discount rate equal to the yield then obtainable from the
United States Treasury Bill or Note with a maturity date closest to the date of
expiration of the Lease Term) by distress or otherwise, provided, however that
Landlord shall utilize commercially reasonable attempts to mitigate its damages.
The accelerated additional rent for expenses shall be calculated by multiplying
the highest additional rent amount for Expenses payable by Tenant in any
calendar year times the number of calendar years (including any fractional
calendar year) remaining in the Lease Term following the date of default. If
Landlord exercises the remedy provided in Subsection (2) above and collects from
Tenant all forms of rent owed for the remainder of the Lease Term, Landlord
shall account to Tenant, at the date of the expiration of the Lease Term for
amounts actually collected by Landlord as a result of reletting, net of the
Tenant's obligations under Subsections 24 B. 2(a)-(c).

                  D. GUARANTY. In addition to the remedies of the Landlord
contained in this Section 24, a separate action or actions may, at Landlord's
option, be brought and prosecuted against the Guarantor, whether or not any
action is first or subsequently brought against Tenant or whether or not Tenant
is joined in any such action. The Landlord may, at its sole option, proceed
against the Tenant without first seeking recourse against the Guarantor and may
pursue any other remedy in Landlord's power whatsoever and the Tenant waives any
right to complain of delay in enforcement of Landlord's rights under this Lease.


         25. RIGHT TO PERFORM FOR OTHER PARTY'S ACCOUNT

                  A. LANDLORD'S RIGHT TO PERFORM. If Tenant fails to observe or
perform any term or condition of this Lease within the grace period, and subject
to required notice, if any, applicable thereto, then Landlord may at any time
thereafter perform the same for the account of Tenant in a commercially
reasonable manner. If Landlord makes any expenditure or incurs any obligation
for the payment of money in connection with such performance for Tenant's
account (including reasonable attorneys' fees and costs in instituting,
prosecuting and/or defending any action or proceeding through appeal), the sums
paid or obligations incurred, with interest at Twelve Percent (12%) per annum,
will be paid by Tenant to Landlord within ten (10) days after rendition of a
bill or statement to Tenant. In the event Tenant in the performance or
non-performance of any term or condition of this Lease should cause an emergency
situation to occur or arise within the Premises or in the Building, Landlord
will have all rights set forth in this paragraph immediately without the
necessity of providing Tenant any advance notice.

                  B. TENANT'S RIGHT TO PERFORM. If, absent an Emergency,
Landlord fails to observe or perform any term or condition of this Lease within
the grace period, if any, applicable thereto, then Tenant may at any time
following ten (10) business days notice perform the same for the account of
Landlord, provided that Tenant shall act in a commercially reasonable manner. If
Tenant makes any expenditure or incurs any obligation for the payment of money
in connection with such performance for Landlord's account (including reasonable
attorneys' fees and costs in instituting, prosecuting and/or defending any
action or proceeding through appeal), the sums paid or obligations incurred,
with interest at Twelve Percent (12%) per annum, will be paid by Landlord to
Tenant within ten (10) days after rendition of a bill or statement to


                                    Page 25
<PAGE>   34
Landlord. The remedy provided in the immediately preceding sentence is not
intended nor shall be construed to avail to Tenant the right to set-off any
current or future Rent. Tenant shall hold harmless and indemnify the Landlord
for any claims arising by or through the work performed by or through Tenant in
its performance which are attributable to the gross negligence or willful
misconduct of Tenant or Tenant's agents in said performance. In the event
Landlord in the performance or non-performance of any term or condition of this
Lease should cause an emergency situation to occur or arise within the Premises
or in the Building, Tenant will have all rights set forth in this paragraph
immediately without the necessity of providing Landlord any advance notice.

         26. LIENS

                  A. GENERAL. In accordance with the applicable provisions of
the "Florida Lien Law" and specifically Florida Statutes, Section 713.10, no
interest of Landlord in the Premises, or in the underlying land or Building of
which the Premises are a part, or the leasehold interest aforesaid shall be
subject to liens for improvements made by Tenant or caused to be made by Tenant
hereunder. Further, Tenant shall have no power or authority to create any lien
or permit any lien to attach to the present estate, reversion, or other estate
of Landlord in the Premises or in the Building, and all mechanics, materialmen,
contractors, artisans and other parties contracting with Tenant or its
representatives or privies as to the Premises or any part of the Premises are
hereby charged with notice that they must look to the Tenant to secure payment
of any bill for work done or material furnished or for any other purpose during
this Lease term. The foregoing provisions are made with express reference to
Section 713.10 of the Florida Statutes. Notwithstanding the foregoing
provisions, Tenant, at its expense, shall cause any liens filed against the
Premises or the Building for work or materials claimed to have been furnished to
Tenant to be discharged of record or properly transferred to a bond under
Section 713.24 of the Florida Statutes within ten (10) days after notice to
Tenant.

                  B. DEFAULT. Notwithstanding the foregoing, if any construction
lien or other lien, attachment, judgment, execution, writ, charge or encumbrance
is filed against the Building or the Premises or this leasehold, or any
alterations, fixtures or improvements therein or thereto, as a result of any
work action or inaction done by or at the direction of Tenant or any of Tenant's
Agents, Tenant will discharge same of record within ten (10) days after the
filing thereof. Further, Tenant agrees to indemnify, defend and save Landlord
harmless from and against any damage or loss, including reasonable attorneys'
fees, incurred by Landlord as a result of any liens or other claims arising out
of or related to work performed in the Premises by or on behalf of Tenant. In
such event, without waiving Tenant's default, Landlord, in addition to all other
available rights and remedies, without further notice, may discharge the same of
record by payment, bonding or otherwise, as Landlord may elect, and upon request
Tenant will reimburse Landlord for all costs and expenses so incurred by
Landlord plus interest thereon at the rate of Twelve Percent (12%) per annum.

         27. NOTICES

                  Notices to Tenant under this Lease will be addressed to Tenant
and mailed or delivered to the address set forth for Tenant in the BLI Rider.
Notices to Landlord under this Lease (as well as the required copies thereof)
will be addressed to Landlord and mailed or delivered to the address set forth
in the BLI Rider. Notices will be personally delivered or given by registered or
certified mail, return receipt requested. As used herein, personal delivery
includes delivery by overnight courier. Notices delivered personally will be
deemed to have been given as of the date of delivery or refusal and notices
given by mail will be deemed to have been given as of the date of delivery or
refusal. Each party may change its address from time to time by written notice
given to the other as specified above.

         28. MORTGAGE; ESTOPPEL CERTIFICATE; SUBORDINATION

                  Landlord has the unrestricted right, subject to the specified
rights of Tenant under this Lease, to convey, mortgage and refinance the
Building, or any part thereof. Tenant agrees, within ten (10) business days
after notice, to execute and deliver to Landlord or its mortgagee or designee
such instruments as Landlord or its mortgagee may require, certifying: (i) the
amount, if any, of the Security Deposit (the parties hereto acknowledging that
Security Deposit has been waived as of the execution of this Lease) and whether
this Lease is in full force and effect and enumerating any modifications, (ii)
the amount of any prepaid Rent paid under this Lease, (iii) the dates to which
the rents and other charges have been paid, (iv) whether or not Tenant claims
any defenses or offsets concerning its obligations under this Lease and whether
or not Landlord is in default in the performance of any covenant, agreement, or
condition contained in this Lease on its part to be performed, and if so,
specify each defense, offset or default of which Tenant may have knowledge. This
estoppel certificate is intended to be for the benefit of Landlord, any
purchaser or mortgagee of Landlord, or any purchaser or assignee of Landlord's
mortgage. The estoppel certificate will also contain such other information as
Landlord or its designee may reasonably request. Nothing contained in this
Section shall constitute a waiver by Landlord of any Event of Default in payment
of Rent or other charges existing as of the date of any notices or certificates
under this Section.

         Provided that any present or future mortgagees or ground lessors shall
have executed a non-disturbance agreement in commercially reasonable form and
substance and at all times will be subject and subordinate to all present and
future mortgages or ground leases which may affect the Building and/or the
parking lot, and to all recastings, renewals, modifications, consolidations,
replacements, and extensions of any such mortgage(s), and to all increases and
voluntary and involuntary advances made thereunder. The foregoing will be

                                    Page 26
<PAGE>   35

self-operative and no further instrument of subordination will be required.
However, in confirmation of this subordination, Tenant shall execute promptly
any certificate that Landlord may reasonably request in order to evidence such
subordination. The failure of Tenant to execute any certificate within twenty
(20) business days following the written demand by Landlord shall constitute a
material default under the terms of this Lease. In the event that the holder
("Lender") of any encumbrance ("Mortgage") on the Building or any other person
acquires title to the Building pursuant to the exercise of any remedy provided
for in the Mortgage or by reason of the acceptance of a deed in lieu of
foreclosure (the Lender, any other such person and their participants,
successors and assigns being referred to herein as the "Purchaser"), Tenant
covenants and agrees to attorn to and recognize and be bound to Purchaser as its
new Landlord, and except as provided below, this Lease shall continue in full
force and effect as a direct Lease between Tenant and Purchaser, except that,
notwithstanding anything to the contrary herein or in the Lease, the provisions
of the Mortgage will govern with respect to the disposition of proceeds of
Landlord's insurance policies or condemnation or eminent domain awards. So long
as the Lease is in full force and effect and Tenant has not committed an Event
of Default under any provision of this Lease, and no Event of Default has
occurred that has continued to exist for a period of time (after notice, if any,
required by this Lease) as would entitle Landlord to terminate this Lease or
would cause without further action by Landlord, the termination of this Lease or
would entitle Landlord to dispossess the Tenant thereunder:

                  A. The right of possession of Tenant to the Premises shall not
be terminated or disturbed by any steps or proceedings taken by Lender in the
exercise of any of its rights under the Mortgage or the indebtedness secured
thereby;

                  B. This Lease shall not be terminated or affected by said
exercise of any remedy provided for in the Mortgage, and any sale by Lender of
the Building pursuant to the exercise of any rights and remedies under the
Mortgage or otherwise, shall be made subject to this Lease and the rights of
Tenant hereunder.

                  C. In no event shall Lender or any other Purchaser be:

                           (1) liable for any act or omission of Landlord or any
prior landlord provided, however, that any liability of the prior landlord shall
not have been released by virtue of the successor landlord's acquisition of
title to the Building; or

                           (2) liable for the return of any security deposit
unless having received any security deposit;

                  D. Intentionally Omitted.

                  E. Tenant acknowledges that Landlord may execute and deliver
to Lender an Assignment of Leases and Rents conveying the rentals under this
Lease as additional security for the loan secured by the Mortgage, and Tenant
hereby expressly consents to such Assignment, provided Tenant receives promptly
upon execution thereof a copy of each such Assignment and further, any such
Assignment does not alter or reduce in any manner whatsoever Tenant's rights as
set forth in this Lease.

                  F. Intentionally Omitted.

                  G. The foregoing provisions shall be self-operative and
effective without the execution of any further instruments on the part of Lender
or Tenant. However, Tenant agrees to execute and deliver to Lender or to any
person to whom Tenant herein agrees to attorn such other instruments as either
shall reasonably request in order to effectuate said provisions.

         29. ATTORNMENT AND MORTGAGEE'S REQUEST

                  A. ATTORNMENT. Subject to the provisions of Section 28, if any
mortgagee of the Building comes into possession or ownership of the Premises, or
acquires Landlord's interest by foreclosure of the mortgage or otherwise, upon
the mortgagee's request Tenant will attorn to the mortgagee.

                  B. MORTGAGE MODIFICATION. If a mortgagee of the Building
requests modifications to this Lease which do not impact upon or impair the
Tenant's rights under this Lease, including, but not limited to, the right of
peaceful and quiet enjoyment, then, provided such modifications are reasonably
acceptable to Tenant, as a condition to disbursing any monies to be secured by
the mortgage, Tenant agrees that within seven (7) days after request by the
mortgagee Tenant will execute, acknowledge and deliver to the mortgagee an
agreement, in form and substance reasonably satisfactory to the mortgagee,
evidencing such modifications, provided that they are reasonably acceptable to
Tenant and do not increase Tenant's obligations under this Lease or materially
adversely affect the leasehold interest created by this Lease.

         30. TRANSFER BY LANDLORD

                  If Landlord's interest in the Building terminates by reason of
a bona fide sale or other transfer, Landlord will, upon transfer of the Security
Deposit to the new owner and the express assumption by the new owner of
Landlord's obligations under this Lease, thereupon be released from all further
liability to Tenant under this Lease. At the expiration or termination of the
Lease Term, Tenant shall deliver to Landlord all keys to the Premises and make
known to Landlord the location and combination of all safes, locks and similar
items.



                                    Page 27
<PAGE>   36

         31. SURRENDER OF PREMISES; HOLDING OVER

                  A. SURRENDER. Tenant agrees to surrender the Premises to
Landlord on the Expiration Date (or sooner termination of the Lease Term
pursuant to other applicable provisions hereof) in as good condition as they
were at the commencement of Tenant's occupancy, ordinary wear and tear, and
damage by fire, windstorm or other insured casualty excepted.

                  B. RESTORATION. In all events, Tenant will promptly restore
all damage caused in connection with any removal of Tenant's personal property.
Tenant will pay, after fifteen (15) days notice to Landlord, all damages that
Landlord may suffer on account of Tenant's failure to surrender possession as
and when aforesaid and will indemnify Landlord against all liabilities, costs
and expenses (including all reasonable attorneys' fees and costs if any) arising
out of Tenant's delay in so delivering possession, including claims of any
succeeding tenant.

                  C. REMOVAL. Upon expiration of the Lease Term, at Landlord's
option, Tenant may not be required to remove from the Premises Building Standard
Items (as defined in the Work Letter), all of such Building Standard Items are
the property of Landlord.

                  D. HOLDOVER. In the event of holding over by Tenant after
expiration of the Lease Term or the earlier termination of this Lease without
the written consent of Landlord. Tenant shall pay as liquidated damages for the
entire holdover period, on a per diem basis, One Hundred Fifty Percent (150%) of
the Rent (calculated on the basis of Rent with respect to the monthly
immediately preceding the month in which expiration or termination occurs) for
the entire holdover period. In the event of any unauthorized holding over,
Tenant shall also indemnify Landlord against all claims for damages by any other
tenant to whom Landlord may have leased all or any part of the Premises covered
hereby effective after the termination of this Lease. No payments of money by
Tenant after the expiration of the Lease Term of the earlier termination of this
Lease will reinstate, continue or extend the Term; reduce the liability of
Tenant to Landlord for damages; or affect any termination notice given by
Landlord to Tenant. No extension of the Lease Term will be valid unless and
until the same will be reduced to writing and signed by both Landlord and
Tenant.

                  E. NO SURRENDER. No offer of surrender of the Premises, by
delivery to Landlord or its agent of keys to the Premises or otherwise, will be
binding on Landlord unless accepted by Landlord, in writing, specifying the
effective surrender of the Premises.

         32. NO WAIVER, CUMULATIVE REMEDIES

                  A. NO WAIVER. No waiver of any provision of this Lease by
either party will be deemed to imply or constitute a further waiver by such
party of the same or any other provision hereof. The rights and remedies of
Landlord and Tenant under this Lease or otherwise are cumulative and are not
intended to be exclusive and the use of one will not be taken to exclude or
waive the use of another, and Landlord and Tenant will be entitled to pursue all
rights and remedies available to landlords and tenants under the laws of the
State of Florida. Landlord, in addition to all other rights which it may have
under this Lease, hereby expressly reserves all rights in connection with the
Building or the Premises, provided Tenant does not, without its prior written
consent, waive any express right provided Tenant under this Lease including
without limitation the right of quiet enjoyment as set forth in this Lease, and
Tenant hereby waives all claims for damages, loss, expense, liability, eviction
or abatement it has or may have against Landlord on account of Landlord's
exercise of its reserved rights, including, but not limited to, Landlord's right
to alter the existing name, address, style or configuration of the Building or
the Common Areas, signage, suite identifications, parking facilities, lobbies,
entrances and exits, elevators and stairwells, subject to the limitations, if
any, contained in this Lease, including, without limitation, the provisions of
Section 7.

                  B. RENT PAYMENTS. No receipt of money by Landlord from Tenant
at any time, or any act, or thing done by, Landlord or its agent shall be deemed
a release of Tenant from any liability whatsoever to pay Rent, Additional Rent,
or any other sums due hereunder, unless such release is in writing, subscribed
by a duly authorized officer or agent of Landlord. Any payment by Tenant or
receipt by Landlord of less than the entire amount due at such time shall be
deemed to be on account of the earliest sum due. No endorsement or statement on
any check or any letter accompanying any check or payment shall be deemed an
accord and satisfaction. In the case of such a partial payment or endorsement,
Landlord may accept such payment, check or letter without prejudice to its right
to collect all remaining sums due and pursue all of its remedies under the
Lease.

         39. HAZARDOUS MATERIALS

                  A. REPRESENTATION. Tenant represents, warrants and covenants
that (1) the Premises will not be used for any dangerous, noxious or offensive
trade or business and that it will not cause or maintain a nuisance there, (2)
it will not bring, generate, treat, store, use or dispose of Hazardous
Substances at the Premises, (3) it shall, with respect to Tenant's use and
occupancy of the Premises, the parking lot and any other area of the Building,
as applicable, at all times comply with all Environmental Laws (as hereinafter
defined) and shall cause the Premises, while in the possession and control of
Tenant to comply, and (4) Tenant will keep the Premises free of any lien imposed
pursuant to any Environmental Laws. Only for purposes of this paragraph entitled
"Representation", the term "Premises" shall mean, only with respect to Tenant's
use and occupancy of the Premises, the Building including Common Areas, parking
areas, greenspace and all other elements thereof.

                  B. REPORTING REQUIREMENTS. Tenant warrants that it will
promptly deliver to the Landlord, (i) copies of any documents received from the
United States Environmental Protection Agency and/or any state, county or
municipal environmental or health agency concerning the Tenant's operations upon
the Premises; (ii) copies of any documents submitted by the Tenant to the United
States Environmental Protection Agency and/or any state, county or municipal
environmental or health agency concerning its operations on the Premises,
including but not limited to copies of permits, licenses, annual filings,
registration forms and, (iii) upon the request of Landlord, Tenant shall provide
Landlord with a letter stating that "to the best of Tenant's knowledge Tenant is
in compliance with Environmental Laws with respect to the Premises."

                  C. TERMINATION, CANCELLATION, SURRENDER. At the Expiration
Date or earlier termination of this Lease, Tenant shall surrender the Premises
to Landlord free of any and all Hazardous Substances which have been placed on,
in or about the Premises by Tenant or Tenant's agents, and in compliance with
all Environmental Laws. Landlord may require, at Tenant's sole expense at the
end of the term, a clean-site certification, environmental audit or site
assessment with respect to the Premises or, if applicable, the Expansion
Premises.

                  D. ACCESS AND INSPECTION. Landlord shall have the right,
subject to not materially disturbing Tenant's peaceful use and occupancy of the

                                    Page 29
<PAGE>   38
Premises and the Common Areas and unreasonable advance notice, except in the
instance of emergencies, but not the obligation, at all times during the term of
this Lease to (i) enter upon and inspect the Premises, (ii) conduct tests and
investigations and take samples to determine whether Tenant is in compliance
with the provisions of this Article, and (iii) request lists of all Hazardous
Substances used, stored or located on the Premises; the cost of all such
inspections, tests and investigations to be borne by Landlord, unless, however,
said inspections, tests and investigations reflect a violation of Environmental
Laws by Tenant in which instance the Tenant shall promptly either pay or
reimburse Landlord for all inspections, tests and investigations. Promptly upon
the written request of Landlord, from time to time, if Landlord shall reasonably
suspect a violation of Environmental Laws, Landlord may obtain an environmental
site assessment or environmental audit report prepared by an environmental
engineering firm acceptable to Landlord to assess, with a reasonable degree of
certainty, the presence or absence of any Hazardous Substances and the potential
costs in connection with abatement, clean-up, or removal of any Hazardous
Substances found on, under, at, or without the Premises. If such audit reveals a
violation of Environmental Laws caused by Tenant or Tenant's agents, or the
presence of Hazardous Substances not in the Premises upon delivery of possession
to Tenant, and such was not caused by Landlord or its agents, the Tenant shall
pay the cost of such audit. Tenant will reasonably cooperate with Landlord, at
no cost or expense to Tenant, and allow Landlord and Landlord's representatives
access, upon ten (10) days notice (except in the case of an emergency), to any
and all parts of the Premises and to the records of Tenant with respect to the
Premises for environmental inspection purposes at any time. In connection
therewith, Tenant hereby agrees that Landlord, or Landlord's agent, may perform
any testing upon or of the Premises that Landlord's deems reasonably necessary
for the evaluation of environmental risks, costs, or procedures, including soils
or other sampling or coring. Landlord shall repair and restore the Premises
damaged during such testing unless testing reveals a violation by Tenant of
Environmental Laws in which case all such expenses shall be that of Tenant.
Landlord shall use reasonable effort to minimize any disruption or interference
with Tenant's operations in the Premises in connection with such testing.

                  E. VIOLATIONS - ENVIRONMENTAL DEFAULTS. Tenant shall give to
Landlord immediate verbal and follow-up written notice of any actual or
threatened spills, releases or discharges of Hazardous Substances on the
Premises, caused by the acts or omissions of Tenant or its agents, employees,
representatives, invitees, licensees, subtenants, customers or contractors.
Tenant covenants to promptly investigate, clean up and otherwise remediate any
spill, release or discharge of Hazardous Substances in or about the Premises or
the Building, including but not limited to those caused by the acts or omissions
of Tenant or its agents, employees, representatives, invitees, licensees,
subtenants, customers or contractors at Tenant's sole cost and expense; such
investigation, clean up and remediation to be performed in accordance with all
Environmental Laws and after Tenant has obtained Landlord's written consent.
Tenant shall return the Premises to the condition existing prior to the
introduction of any such Hazardous Substances by Tenant or Tenant's agents.

                           (1) In the event of (1) a violation of an
Environmental Law by Tenant, (2) a release, spill or discharge of a Hazardous
Substance on or from the Premises, or (3) the discovery of an environmental
condition requiring response which violation, release, or condition is
attributable to the acts or omissions of Tenant, its agents, employees,
representatives, invitees, licensees, subtenants, customers, or contractors, or
(4) an emergency environmental condition which is the result of an act of Tenant
(collectively "Environmental Defaults"), Landlord shall have the right, but not
the obligation, within ten (10) business days after notice to Tenant, except in
the case of an emergency which requires more prompt action, to enter the
Premises, to supervise and approve any actions taken by Tenant to address the
Environmental Default; and in the event Tenant fails to immediately address such
Environmental Default, then Landlord may perform, at Tenant's expense, any
lawful actions necessary to address the Environmental Default.

                           (2) Landlord has the right, but not the obligation to
cure any Environmental Defaults, has the right to suspend some or all of the
operations to the extent that the operations have caused the Environmental
Default of the Tenant until it has determined to its sole satisfaction that
appropriate measures have been taken, and has the right to terminate this Lease
upon the occurrence of an Environmental Default.

                  F. ADDITIONAL RENT. Any expenses which the Landlord incurs,
which are to be at Tenant's expense pursuant to this Article, will be considered
Additional Rent under this Lease and shall be paid by Tenant on demand by
Landlord.

                  G. ASSIGNMENT AND SUBLETTING. Notwithstanding anything to the
contrary in this Lease, the Landlord may condition its approval of any
assignment or subletting by Tenant to an Assignee or Subtenant that in the
judgment of the Landlord, reasonably exercised, does not create any additional
environmental exposure.

                  H. INDEMNIFICATIONS.

                           (1) INDEMNIFICATION OF LANDLORD. Tenant shall

person or entity pursuant to the provisions of the United States Bankruptcy
Code, 11 U.S.C. Section 101 et seq. (the "Bankruptcy Code"), any and all monies
or other consideration payable or otherwise to be delivered in connection with
such assignment shall be paid or delivered to Landlord, shall be and remain the
exclusive property of Landlord, and shall not constitute the property of Tenant
or of the estate of Tenant within the meaning of the Bankruptcy Code. Any and
all monies or other considerations constituting Landlord's property under this
Section not paid or delivered to Landlord shall be held in trust for the benefit
of Landlord and shall be promptly paid or delivered to Landlord. Any person or
entity to which this Lease is assigned pursuant to the provisions of the
Bankruptcy Code shall be deemed without further act or deed to have assumed all
of the obligations arising under this Lease on and after the date of such
assignment. For purposes of this Lease, an "Event of Bankruptcy" shall mean the
filing of a voluntary petition by Tenant or the entry of an order for relief
against Tenant, under Chapter 7, 11 or 13 of the Bankruptcy Code (or the
conversation to a Chapter 11 or 13 proceeding of a proceeding that is filed by
or against Tenant under any other Chapter of the Bankruptcy Code).

                  B. ADDITIONAL REMEDIES. In addition to any rights or remedies
hereinbefore or hereinafter conferred upon Landlord under the terms of this
Lease,

                                    Page 31
<PAGE>   40

the following remedies and provisions shall specifically apply in the event
Tenant is in default of this Lease:

                           (1) In all events, any receiver or trustee in
bankruptcy shall either expressly assume or reject this Lease within sixty (60)
days following the entry of an "Order for Relief" or within such earlier time as
may be provided by applicable law.

                           (2) In the event of an assumption of this Lease by a
debtor or by a trustee, such debtor or trustee shall within thirty (30) days
after such assumption (i) cure any default or provide adequate assurance that
defaults will be promptly cured; (ii) compensate Landlord for actual loss or
provide adequate assurance that compensation will be made for actual losses,
including, but not limited to, all attorneys' fees and costs incurred by
Landlord resulting from any such proceedings; and (iii) provide adequate
assurance of future performance.

                           (3) Where an Event of Default exists under this
Lease, the trustee or debtor assuming this Lease may not require Landlord to
provide services or supplies incidental to this Lease before its assumption by
such trustee or debtor, unless Landlord is compensated under the terms of this
Lease for such services and supplies provided before the assumption of such
Lease.

                           (4) The debtor or trustee may only assign this Lease
if (i) it is assumed and the assignee agrees to be bound by this Lease, (ii)
adequate assurance of future performance by the assignee is provided, whether or
not there has been a default under this Lease, and (iii) the assignee has been
approved by Landlord in accordance with Section 13 or is an assignee permitted
under Section 13. Any consideration paid by any assignee in excess of the rental
reserved in this Lease shall be the sole property of, and paid to, Landlord.

                           (5) Landlord shall be entitled to the fair market
value for the Premises and the services provided by Landlord (but in no event
less than the rental reserved in this Lease) subsequent to the commencement of
an Event of Bankruptcy.

                           (6) Any security deposit given by Tenant to Landlord
to secure the future performance by Tenant of all or any of the terms and
conditions of this Lease shall be automatically transferred to Landlord upon the
entry of an "Order of Relief", such being deemed a material part of the
consideration for Landlord's agreement to enter into this Lease.

                           (7) The parties agree that Landlord is entitled to
adequate assurance of future performance of the terms and provisions of this
Lease in the event of an assignment under the provisions of the Bankruptcy Code.
For purposes of any such assumption or assignment of this Lease, the parties
agree that the term "adequate assurance" shall include, without limitation, at
least the following: (i) any proposed assignee must have, as demonstrated to
Landlord's reasonable satisfaction, a net worth (as defined in accordance with
generally accepted accounting principles consistently applied) in an amount
sufficient to assure that the proposed assignee will have the resources to meet
the financial responsibilities under this Lease, including the payment of all
Rent; the financial condition and resources of Tenant are material inducements
to Landlord entering into this Lease; (ii) any proposed assignee must have
engaged in the permitted use described in the BLI Rider for at least five (5)
years prior to any such proposed assignment, the parties hereby acknowledging
that in entering into this Lease, Landlord considered extensively Tenant's
permitted use and determined that such permitted business would add
substantially to the tenant balance in the Building, and were it not for
Tenant's agreement to operate only Tenant's permitted business on the Premises,
Landlord would not have entered into this Lease, and that Landlord's operation
of the Building will be materially impaired if a trustee in bankruptcy or any
assignee of this Lease operates any business other than Tenant's permitted
business; (iii) any assumption of this Lease by a proposed assignee shall not
adversely affect Landlord's relationship with any of the remaining tenants in
the Building taking into consideration any and all other "use" clauses and/or
"exclusivity" clauses which may then exist under their leases with Landlord; and
(iv) any proposed assignee must not be engaged in any business or activity which
it will conduct on the Premises and which will subject the Premises to
contamination by any Hazardous Materials.

         41. FIRE PREVENTION SYSTEMS

                  The Tenant shall be responsible for the cost of any change,
modification, alteration or installation of any new or existing sprinkler
system, fire extinguishing system and/or fire detection system which may now or
hereafter be required as follows:

                  A. If the National Board of Fire Underwriters or any local
Board of Fire Underwriters or Insurance Exchange (or other bodies hereafter
exercising similar functions) shall require or recommend the installation of
fire extinguishers, a "sprinkler system," fire detection and prevention
equipment (including, but not limited to, smoke detectors and heat sensors), or
any changes, modifications, alterations, or the installation of additional
sprinkler heads or other equipment for any existing sprinkler, fire
extinguishing system, and/or fire detection system for any reason, whether
attributable to Tenant's use of the Premises or Alterations performed by Tenant;
OR

                  B. If any law, regulation, or order or if any bureau,
department, or official of the Federal, State, and/or Municipal Governments
shall require or recommend the installation of fire extinguishers, a "sprinkler
system," fire detection and prevention equipment (including, but not limited to,
smoke detectors and heat sensors), or any changes, modifications, alterations,
or the installation of additional sprinkler heads or other equipment for any
existing sprinkler system, fire extinguishing system, and/or fire detection
system for any




                                    Page 32
<PAGE>   41

reason, whether attributable to Tenant's use of the Premises or Alterations
performed by Tenant; OR

                  C. If any such installations, changes, modifications,
alterations, sprinkler heads, or other equipment become necessary to prevent the
imposition of a penalty, an additional charge, or an increase in the fire
insurance rate as fixed by said Board or Exchange, from time to time, or by any
fire insurance company as a result of the use of the Premises whether or not the
same is a Permitted Use under this Lease.

                  In the event the required work is in the Premises and Tenant
fails to perform same, or if it is outside and related to the Premises, Landlord
may elect to perform the work and charge the cost thereof to Tenant as
Additional Rent and Tenant shall pay, each year during the Lease Term, the cost
amortized over the balance of the Lease Term, (amortized, with interest at the
rate of Ten Percent (10%) per annum, over the lesser of (a) the balance of the
Lease but in no event longer than ten (10) years, or (b) the useful life of the
asset per GAAP), provided, however, that if the balance of the term of the Lease
is less than five (5) years the amortization shall be over the shorter of the
useful life of the item, in accordance with GAAP or five (5) years, unless,
however, the Lease is subsequently renewed in which event the amortization shall
be recalculated during the renewal period on a pro-rata basis with interest on
all amortized periods at the rate of Ten Percent (10%) per annum. If the
Landlord does not elect to perform such work, the Tenant shall immediately
proceed, at its sole cost, to perform the work upon the following conditions:

                  A. a general contractor licensed in Florida and approved by
Landlord shall be utilized

                  B. all laws, ordinances and regulations governing such work
shall be complied with

                  C. a payment and performance bond in Landlord's favor and with
a surety acceptable to Landlord shall be obtained if required by Landlord's
insurance carrier(s) or governmental authority

                  D. the construction contract and all plans and specifications
for the work shall be subject to Landlord's approval.

         42. SPECIAL EVENTS

         The Tenant shall not, without the prior written consent of the
Landlord, which consent shall not be unreasonably withheld or delayed, schedule,
advertise or undertake any exposition, promotion or other type of special event
at the Premises. Any approval of the Landlord to a special event may include,
but not be limited to, at the Landlord's option, to conditions such as
guidelines for traffic and pedestrian control, security, parking and other
considerations in the interest of maintaining the health and safety for both the
Tenant's invitees as well as that of other tenants.

         43. MISCELLANEOUS

                  A. If Tenant has a lease for other space in the Building, an
Event of Default by Tenant under such lease will constitute a default hereunder.

                  B. If any term or condition of this Lease or the application
thereof to any person or circumstance is, to any extent, invalid or
unenforceable, the remainder of this Lease, or the application of such term or
condition to persons or circumstances other than those as to which it is held
invalid or unenforceable, is not to be affected thereby and each term and
condition of this Lease is to be valid and enforceable to the fullest extent
permitted by law. This Lease will be construed in accordance with the laws of
the State of Florida.

                  C. Submission of this Lease to Tenant does not constitute an
offer, and this Lease becomes effective only upon execution and delivery by both
Landlord and Tenant.

                  D. Tenant acknowledges that it has not relied upon any
statement, representation, prior or contemporaneous written or oral promises,
agreements or warranties, except such as are expressed herein.

                  E. Intentionally omitted.

                  F. If Tenant, with Landlord's consent, occupies the Premises
or any part thereof for the purpose of conducting business prior to the Rent
Commencement Date all provisions of this Lease will be in full force and effect
commencing upon such occupancy, and Base Rent and Additional Rent, where
applicable, for such period will be paid by Tenant at the same rate herein
specified.

                  G. Each party represents and warrants that it has not dealt
with any agent or broker in connection with this transaction except for Blue
Lake Realty, Inc. and the agents or brokers specifically set forth in the BLI
Rider whose commissions shall be paid by Landlord pursuant to separate
agreement. If either party's representation and warranty proves to be untrue,
such party will indemnify the other party against all resulting liabilities,
costs, expenses, claims, demands and causes of action, including reasonable
attorneys' fees and costs through all appellate actions and proceedings, if any.
The foregoing will survive the end of the Lease Term.

                  H. Neither this Lease nor any memorandum hereof will be
recorded by Tenant.

                  I. Nothing contained in this Lease shall be deemed by the
parties hereto or by any third party to create the relationship of principal and
agent, partnership, joint venturer or any association between Landlord and
Tenant, it being expressly understood and agreed that neither the method of

the sole expense of Tenant. Unless Landlord otherwise requests or consents in
writing, all of Tenant's telecommunications equipment shall be and remain solely

specifically agreed to in writing, Landlord shall have no responsibility for the
maintenance of Tenant's telecommunications or data equipment, including wiring;
nor for any wiring or other infrastructure to which Tenant's telecommunications
or data equipment may be connected. Tenant agrees that, to the extent any such
service is interrupted, curtailed or discontinued, Landlord shall have no
obligation or liability with respect thereto and it shall be the sole obligation
of Tenant at its expense to obtain substitute service, unless the interruption,
curtailment or discontinuance is caused by the gross negligence of willful
misconduct of Landlord.

and all telecommunications and data equipment installed in the Premises or
elsewhere in the Building or the Building by or on behalf of Tenant, including

provider shall be permitted to install its line within the Building without
first securing the prior written approval of Landlord, which approval may be
arbitrarily withheld. The Landlord's approval, if given, shall not be deemed any
kind of warranty or representation by Landlord, including without limitation,
any warranty or representation as to the suitability, confidence, or financial
strength of the provider without limitation of the foregoing standard and may be
conditioned upon such terms as shall be determined by Landlord in its sole
judgment.

used by another party, Tenant shall assume all liability related to such
interference. Tenant shall use reasonable efforts, and shall cooperate with
Landlord and other parties to promptly eliminate such interference. In the event

sole cost, expense and risk of Tenant, and shall do so in a good, workmanlike
manner and in compliance with all federal, state, and local building, zoning,
electric, telecommunications and safety codes, ordinances, standards,
regulations, laws, and requirements, including, without limitation, those of the

or Alterations.

                              WORK LETTER AGREEMENT

         In the event of any inconsistencies between this Agreement and the
Lease dated currently herewith to which this Agreement is attached as Exhibit
"B", this Agreement shall control. Capitalized terms used in this Agreement
shall, unless otherwise specifically set forth herein, have the same meanings as
in the Lease.

1. Tenant shall complete or cause the completion of improvements to the Premises
as shown on the Final Plans (defined below) and as more fully described in this
Section (the "Work"). Tenant shall retain an architect and engineer from and
amongst a group which shall consist of a published list of pre-approved
architects and engineers and, for purposes of this Work Letter Agreement,
Nichols/Page Design Associates, Inc., (all of whom shall be licensed in the
State of Florida) to prepare complete and detailed architectural plans and
specifications, and structural, mechanical and engineering plans and
specifications, showing the Work (collectively, the "Construction Plans"). The
cost of the Construction Plans shall be the responsibility of Tenant. The
Construction Plans shall be prepared in a manner as will be acceptable to
Landlord in its reasonable discretion. The Work shall meet or exceed the minimum
standards for the Work ("Minimum Building Materials and Construction") attached
hereto as Exhibit "B-1" and otherwise as determined by Landlord in its
reasonable discretion. It is the intent of the parties that Exhibit "B-1" set
forth the minimum quality of the Work, however, Exhibit "B-1" shall not be
construed to require any particular quantity of the items described therein
except to the extent required by applicable codes or laws. The Construction
Plans shall be consistent with all applicable laws, codes, ordinances and
regulations, including but not limited to the Americans with Disabilities Act of
1990, of governmental and quasi-governmental entities having jurisdiction
regarding the Work and/or the Building.

2. Tenant shall deliver Construction Plans to Landlord for Landlord's approval.
Landlord shall respond to Tenant's request for approval of Tenant's Construction
Plans within ten (10) business days of their submission, during which time the

reasonably disapprove of all or a portion of Tenant's Construction Plans, it
shall set forth its reasons therefor in writing in reasonable detail within such
ten (10) business day period. Tenant shall be required to incorporate any
reasonable changes to the Construction Plans as required by Landlord. Landlord
or Landlord's Consultants shall respond to Tenant's request for consent of its
revised plans within three (3) business days of submission unless the revisions

business days thereafter. Neither the recommendation or designation by the
Landlord of a pre-approved list of architects or contractors, nor the consent by
the Landlord of the inclusion of Nichols/Page Design Associates, Inc. as an

approval of the Construction Plans by Landlord shall be deemed to create any
liability on the part of Landlord with respect to the Construction Plans
(whether with respect to design, functionality, specifications, compliance with
legal requirements or otherwise). Tenant shall reimburse Landlord for reasonable
architect, engineer and other professional fees incurred by Landlord in
connection with review of Tenant's Construction Plans and Revisions; estimated

reimbursement, (ii) reimbursement shall be limited to customary rates, and (iii)

Plans, Tenant at its expense shall correct same forthwith. Only new, first class
materials shall be used in the performance of the Work. At all times during the
construction of the Work, it shall be Tenant's responsibility to cause each of
Tenant's contractors and subcontractors to maintain protection of the Premises

good cause shall have the right to require Tenant to terminate any construction
work at any time being performed by or on behalf of Tenant in the Premises, and

the Building. Upon written notification, setting forth in reasonable detail such
good cause, from Landlord to Tenant to cease any work, Tenant shall forthwith
remove from the Premises all agents, employees and contractors of Tenant

unreasonably withheld or delayed), and Tenant shall have no claim for damages of
any nature whatsoever against Tenant in connection therewith.

certified copy of such Notice of Commencement has been posted on the
construction site, and an Affidavit of such posting is furnished to Landlord.

written consent to the form and content of same which shall not be unreasonably
withheld or delayed. The form of the Notice of Commencement shall be in

                              OCCUPANCY AGREEMENT

     OCCUPANCY AGREEMENT, (this "Agreement") made as of this 22nd day of
January, 1998, between BLUE LAKE, LTD., a Florida limited partnership, as OWNER,
and DATABASE TECHNOLOGIES, INC., a corporation organized under the laws of the
State of Florida, as OCCUPANT.


                                   RECITALS:

     A.   Occupant is the "Tenant" under that certain Lease dated January 22,
1998, (the "Lease") with BLUE LAKE, LTD., (the "Landlord"), with respect to
certain leasehold premises (the "Premises") being a portion of 4530 Blue Lake
Drive, (Building #14) and a portion of 4800 Blue Lake Drive (Building #2) of
Blue Lake Corporate Center (the "Building").

     B.   The Premises have not been completed for Tenant's occupancy as of the
date of this Agreement.

     C.   Pending the completion of tenant improvements in and to the Premises,
Occupant has requested of the Owner the temporary use and occupancy of certain
other space at the Blue Lake Corporate Center (the "Project").

     D.   Owner has agreed to allow Occupant to have use of certain space as
herein below defined and provided. As an accommodation and convenience to the
Occupant, Owner has agreed to allow Occupant to have the temporary occupancy and
use of certain space, as hereinbelow defined, at the Project.

     NOW, THEREFORE, Owner and Occupant, intending to be legally bound hereby,
agree as follows:

     1.   OCCUPANCY SPACE.  The Owner hereby grants to Occupancy a temporary
non-exclusive license and business concession to occupy that space consisting of
approximately 6,000 rentable square feet in the Building having an address of
Building 004, 4680 Blue Lake Drive, Boca Raton, Florida 33431, and outlined on
the diagram attached hereto as Exhibit "A" (the "Occupancy Space") for a
month-to-month term initiating on the date hereof, and, unless sooner terminated
at any time by the Owner upon five (5) days written notice to the Tenant or
unless sooner terminated pursuant to the terms and conditions of this Agreement
or the Lease, terminating concurrently with the Commencement Date of the Lease,
on the terms and conditions provided herein. The parties acknowledge that the
approximation of space is based on an estimate in that the space is a
non-secured, non-demised space allocated to the Tenant solely as an
accommodation.

     2.   OCCUPANCY CHARGES.  The Occupant will pay to the Owner a charge of
$2,750.00 per month, plus applicable Florida sales tax (the "Occupancy Charge"),
payable in advance at the office of the Owner, without notice, on the first day
of each calendar month during the term of this Occupancy Agreement. Except that
if the Term begins or ends on a day which is not the first or last day of the
month, the Occupancy Charge for such month shall be pro-rated. The Incidental
Charges shall be billed to Occupant at the end of the month in which they are
incurred and payment shall be due within five (5) days of the date of the
invoice. The Occupancy Charge includes charges for the Owner to provide HVAC
services to the Occupancy Space (during regular Business Hours as defined in the
Lease) and restroom supplies and janitorial services in the adjacent restroom.
The provisions of Section 8.A.(2) of the Lease providing for the Landlord's
charges for the delivery of HVAC services, during other than Business Hours, are
hereby specifically incorporated herein and shall apply to the Occupancy Space.
In addition to the foregoing, the Occupant shall be responsible for payment of
invoices for all other services including, but not limited to, (i) janitorial
services for the interior of the Occupancy Space, (ii) any changes to door
locks, which change of locks shall be undertaken by Tenant which shall provide
keys to Landlord, and (iii) any construction to the interior of the Occupancy
Space, all of which shall be subject to the prior written approval of Owner
which approval shall not be unreasonably withheld or delayed. The Occupancy
Charge does not include fees for janitorial services, security services or any
other services required by Occupant shall be separately contracted and paid for
by Occupant. In addition to the Occupancy Charge the Owner shall charge the
Occupant such reasonable incidental charges for services as may, from
time-to-time, be provided to Occupant by or through the offices of the Owner
(the "Incidental Charges").



                                       1

     3.   USE. Occupant will use the Occupancy Space solely for office and for
access to the facilities and areas made available to Occupant under this
Agreement and for no other purpose. Occupant will not (i) demise the Occupancy
Space; (ii) interfere with another occupant or tenant, (iii) store any property
other than in the Occupancy Space, (iv) allow any other person (other than
Tenant's agents or invitees) to use the Occupancy Space, or (v) deface, damage
or alter other than approved alterations on the Occupancy Space or Owner's
equipment. The Occupant is granted access to the Occupancy Space on a
twenty-four (24) hour-per-day, seven (7) days-per-week, subject, however, to
reasonable such rules and conditions promulgated in waiting and provided to
Tenant from time-to-time by the landlord as to such access, such as but not
limited to: (i) location of parking, (ii) wearing of security badges, (iii)
designated doors for entry to the Building, and (iv) check-in of all employees,
invitees, or Occupant's agents entering the Building and the Occupancy Space.


     4.   LEASE CONDITIONS. This Occupancy Agreement is in all respects
subject and subordinate to, and to the extent not otherwise in conflict with the
provisions hereof, incorporates and restates the Lease as if fully recited
herein. Accordingly, for the purpose of example but not limitation, the security
deposit, if any, previously delivered to the Landlord shall secure the
obligations of the Occupant under this Agreement. This Occupancy Agreement shall
be subject to all terms of the insurance provisions of the Lease and shall not
be effective until such time as an Insurance Certificate is attached herein.
Occupant shall, except to the extent otherwise in conflict with the provisions
hereof, comply with all monetary and non-monetary terms and conditions of the
Lease, including, without limit, the listed Rules and Regulations as they may be
amended by Landlord from time to time and recognizes that its failure to do so
following receipt of any required written notice provided in the Lease, shall
constitute a default under this Agreement. In such case, Landlord shall not be
liable for any previous act or omission of the Licensor under this License. In
the event of the existence of any inconsistencies between the provisions of the
Lease and this Occupancy Agreement as it relates solely to the Occupancy Space,
the provisions of this Occupancy Agreement shall control.

     In the event that Occupant, as Tenant under the Lease, defaults under the
Lease resulting in the termination of the Lease or re-entry or dispossession by
Landlord of the Occupancy Space under the Lease, this Occupancy Agreement and
all rights of the Occupant hereunder shall immediately terminate.

     5.   TERMINATION OF OCCUPANCY AGREEMENT. On the day occupancy under this
Agreement terminates, Occupant will deliver possession of the Occupancy Space
empty, broom clean and in the same condition (reasonable wear and tear excepted)
as it was on the date of this Agreement, provided, however, that Tenant need not
remove or change any improvements to the Occupancy Space. If Occupant does not
leave the Occupancy Space empty and broom clean, Occupant will reimburse Owner,
on demand, reasonably incurred cleaning charges. Occupant will also be
responsible for and shall pay for any damage Occupant causes to the Occupancy
Space.

     6.   INSURANCE. Notwithstanding anything herein contained to the
contrary, this Occupancy Agreement is made specifically contingent upon the
delivery by the Occupant of the delivery of a policy of insurance or certificate
of insurance naming the Owner as an additional insured as its interest may
appear in accordance with the terms of the Lease, a copy of which insurance
certificate is to be attached hereto. All provisions of Paragraph 14 of the
Lease regarding insurance responsibilities of the Tenant shall be applicable
herein and further Occupant agrees that it will indemnify and save harmless
Landlord and its employees and agents from any and all liability, damages,
expenses, suit and costs of defense (including reasonable counsel fees) arising
from any injury to person or property in or on the Occupancy Space, or the
Building to the extent arising out of the act, omission, or negligence of
Occupant, its agents, employees or invitees, or Occupant's use of the Occupancy
Space or the Building.

     7.   PERSONAL PROPERTY; PERSONAL INJURY.

           a.   All personal property of Occupant, its employees, agents,
invitees, clients or guests, in and on the Occupancy Space or any part of the
Building, including the loading areas, shall be at the sole risk of said
parties and Landlord except to the extent of Landlord's gross negligence or
willful misconduct, shall not in any event be liable to any such person or party
for any damage to or loss thereof including, without limit, any damage caused by
the bursting, leaking or overflowing of water, sewer or sprinkler pipes or
plumbing fixtures, as the case may be and then only to the extent that Occupant
is not compensated therefore by insurance provided, however, that in no event
shall Landlord or its representative agents be liable for the interruption of or
loss to Occupant's business or for any indirect damages or consequential losses
arising as a result of such damage or loss.

           b.   Landlord shall not be liable for any personal injury to Occupant
or Occupant's employees, agents, business invitees, customers or guests arising
from the use and condition of the Occupancy Space or any part of the Building or
Project, except to the extent of Landlord's gross negligence or willful
misconduct.

<PAGE>   61
    8.   DISPUTES. Occupant acknowledges that this Occupancy Agreement is not a
lease or a sublease of space but it is merely entered into by the Owner as an
accommodation to the Occupant so as to allow the Occupant to utilize the
Occupancy Space pending the Commencement of the Lease. Accordingly, the Owner
and Occupant acknowledge and agree that this Occupancy Agreement is not
controlled by or subject to the provisions of Florida Statute Chapter 83. The
parties hereby waive trial by jury in any action brought by either of them
arising in any way in connection with this Occupancy Agreement including,
without limit, the relationship of Owner and Occupant and/or any claim of injury
or damage. Occupant hereby waives any and all notice periods provided by law
for tenants including, without limit, the notice to quit and the notice of a
Landlord's intention to re-enter the Occupancy Space. Occupant shall, promptly
upon Owner's request deliver all instruments necessary to confirm this Occupancy
Agreement. In such event, Licensee shall also, promptly upon Landlord's request,
execute and deliver all instruments necessary to confirm Licensee's recognition
of Landlord as licensor. Licensee waives all rights under any present or future
law to elect to terminate this License by reason of the termination of the
Lease.

     9.   RELATIONSHIP.  It is agreed that nothing contained in this Occupancy
Agreement shall be deemed or construed as creating a partnership, joint venture
or a relationship of Landlord and Tenant between Owner and Occupant as relates
to the Occupancy Space.

     10.  DEFAULT.  If Occupant shall fail to pay the Occupancy Fee or any
Incidental Charges within five (5) days after the date any such charge is due,
or shall otherwise violate any of the provisions of this Occupancy Agreement or
any of the terms and conditions of the Lease, and, upon written notice, fails to
cure such violation within the time periods provided in the Lease, Occupant
shall be in default and upon request of Owner shall immediately vacate the
Occupancy Space. In such case, Owner shall be entitled to recover in addition to
damages otherwise established by Owner, Owner's reasonable attorneys' fees and
expenses incurred in removing Occupant from the Occupancy Space or prosecuting
such claim, and, in addition, the Owner, as Landlord under the Lease, may pursue
all remedies available to Landlord under the Lease.

     11.  NO ORAL AGREEMENT.  This Agreement states the entire occupancy
agreement between the parties and there are no other representatives, promises
or agreements between them. No agreement or waiver will be effective unless in
writing, signed by both parties.

     12.  NO WAIVER.  The failure of Owner on previous occasions with this
occupancy agreement or the Rules and Regulations will not prevent Owner from
taking action for subsequent non-compliance. The receipt of occupancy charges
with knowledge of non-compliance is not a waiver on non-compliance.

     13.  NOTICES.  Any notice given under this Occupancy Agreement pursuant to
law must be in writing and will be sufficient if mailed or delivered to the
address set forth in notice, and if to Occupant, also to the Occupancy Space.
The address and telephone of Owner set forth below are to be used by the
Occupant in making inquiries concerning this Occupancy Agreement.

     14.  WAIVER OF TRIAL BY JURY; NO COUNTERCLAIMS.   Occupant waivers trial by
jury in any action, proceeding or counterclaim brought by Owner specifically
under this Occupancy Agreement and agrees not to interpose any counterclaim or
offset of any kind whatsoever.

     15.  BINDING EFFECT OF AGREEMENT.  This Occupancy Agreement will bind and
benefit the parties and their respective heirs, executors, administrators,
successors and assigns.

         IN WITNESS WHEREOF, the parties hereto have executed the foregoing
Agreement on the day and year first written above.

increase on the same Rent change dates as for the Premises (as defined in the
Lease), and other charges or payments of any kind as set forth in the Lease,
subject; however, as applicable, to the Free Rent provisions of the Lease, as

         4. DBT'S NON-EXCLUSIVE OPTION TO LEASE THE OPTION PREMISES/RIGHT OF
            FIRST REFUSAL DURING NON-EXCLUSIVE OPTION TERM.

                  4.1      NON-EXCLUSIVE OPTION (APRIL 1, 1999 - JUNE 30, 1999).

                           4.1.1 GRANT OF NON-EXCLUSIVE OPTION TO LEASE OPTION
PREMISES (APRIL 1, 1999 THROUGH JUNE 30, 1999). In the event that DBT shall not
have exercised the Exclusive Option granted in Section 3 of this Grant on or
before March 31, 1999, DBT is nonetheless granted a non-exclusive option (the
"Non-Exclusive Option") exercisable from April 1, 1999 through June 30, 1999, to
lease not less than all of the Option Premises on the terms and conditions of
this Section 4.

                           4.1.2 EXERCISE OF NON-EXCLUSIVE OPTION. DBT may
exercise the Non-Exclusive Option by delivering written notice to Blue Lake of
its exercise of the Non-Exclusive Option on or before June 30, 1999.

                           4.1.3 COMMENCEMENT DATE. DBT's written exercise of
the Non-Exclusive Option shall designate a Commencement Date for the lease of
the Option Premises which Commencement Date shall be on or before July 1, 1999.

                           4.1.4 LEASE. Within five (5) days of DBT's exercise
of the Non-Exclusive Option, DBT shall enter into a lease with Blue Lake for
entire Option Premises in accordance with all of the terms and conditions of the
Lease, as defined in Section 11 and as more specifically provided for in Section
3.4 of this Grant.

                  4.2 RIGHT OF FIRST REFUSAL DURING NON-EXCLUSIVE OPTION TERM.
If during the Non-Exclusive Option Term, Blue Lake shall, prior to an exercise
by DBT of the Non-Exclusive Option, pursuant to Section 4.1 above, receive a
BONA-FIDE third party offer to lease all or a portion of the Option Premises
("Third Party Offer") then Blue Lake shall advise DBT, in writing, of Blue
Lake's intention to accept such Third Party Offer and shall furnish to DBT all
of the basic terms and conditions of such Third Party Offer (the "Offer
Notice"). DBT shall thereafter have the option, within seven (7) business days
following DBT's receipt of the Offer Notice to: (a) request that Blue Lake
relocate the Option Premises to another location of Blue Lake's selection in
accordance with the terms of Section 6 hereof, or should there not be available
space to relocate the Option Premises, (b), either (i) exercise the
Non-Exclusive Option to lease the entire Option Premises (notwithstanding a
Third Party Offer for the lease of less than all of the Option Premises), the
Commencement Date for said lease being not later than July 1, 1999, on the terms
of and in accordance with the Lease, subject, however, to the provisions of
Section 12 herein as to Free Rent or (ii) exercise the herein granted Right of
First Refusal to lease, at a minimum, not less than the entire square footage
portion of the Option Premises made subject to the Third Party Offer contained
in the Offer Notice in accordance with the terms contained in the Offer Notice,
or (iii) waive its exercise of both its Non-Exclusive Option and its Right of
First Refusal as to the then pending Offer Notice. If DBT waives or fails to
timely exercise its Non-Exclusive Option, Blue Lake may then lease such portion
of the Option Premises as set forth in such offer to any other party, including
the third party offerer and the Non-Exclusive Option and the Right of First
Refusal granted in Section 4.1 and 4.2, respectively, of this Grant, shall
thereafter be terminated on a self-effectuating basis and be of no further force
and effect with respect to only such space which is leased to a third party.
Notwithstanding the foregoing, the Non-Exclusive Option and the Right of First
Refusal granted in this Section 4, shall remain in full force and effect in
adherence and conformance with the terms herein provided until June 30, 1999, to
the extent there remains any portion of the Option Premises not leased to a
third party.

<PAGE>   69

         5. SECOND RIGHT OF FIRST REFUSAL (JULY 1, 1999-JUNE 31, 2002). Provided
that all of the Option Premises have not been previously leased by DBT pursuant
to the Exclusive Option, Non-Exclusive Option or the Rights of First Refusal
granted in Sections 3 and 4, and further provided that this Grant has not been
waived by affirmative waiver or failure by DBT to exercise its Non-Exclusive
Option to a Third Party Offer as to the entire Option Premises which has been
accepted by DBT as to the entire Option Premises, Blue Lake hereby grants to DBT
a Second Right of First Refusal (the "Second Right of First Refusal"),
commencing on July 1, 1999 and expiring on June 31, 2002 (the "Second Right
Term") to lease the remaining unleased portion of the Option Premises upon the
terms and conditions herein provided. If during the Second Right Term Blue Lake
shall receive a BONA-FIDE third-party offer to lease space which shall include
all or a portion of the remaining unleased portion of the Option Premises
("Third Party Offer"), Blue Lake shall notify DBT in writing of Blue Lake's
intention to accept such Third Party Offer and shall furnish to DBT all of the
basic terms and conditions of such Third Party Offer (the "Offer Notice"). DBT
shall thereafter have the option, within seven (7) business days following DBT's
receipt of the Offer Notice to either (a) exercise the herein granted Right of
First Refusal to lease, at a minimum, not less than the entire square footage
portion of the Option Premises made subject to the Third Party Offer contained
in the Offer Notice in accordance with the terms contained in the Offer Notice,
or (b) waive its exercise of its Right of First Refusal as to the then pending
Offer Notice. If DBT waives or fails to timely exercise its Right of First
Refusal, Blue Lake may then lease such portion of the Option Premises as set
forth in such offer to any other party, including the third party offerer and
Right of First Refusal granted in this Section 5 shall thereafter be terminated
on a self-effectuating basis and be of no further force and effect with respect
to only such space which is leased to a third party. Notwithstanding the
foregoing, the Right of First Refusal granted in this Section 5, shall remain in
full force and effect until June 31, 2002, to the extent there remains any
portion of the Option Premises remaining available for lease. Notwithstanding
the immediately preceding sentence, Blue Lake may, additionally, request that
DBT execute a written certification of the lapse and termination of the Second
Right of First Refusal (to the extent so terminated) as herein contained with
respect to such space.

         6. RELOCATION OF THE OPTION PREMISES. Notwithstanding anything herein
to the contrary, Blue Lake may, except, however, as to certain election rights
of DBT during the pendency of the Options herein contained between the Effective
Date of this Grant and June 30, 1999, from time to time during the terms of the
options herein granted and without a triggering of the relocation by a Third
Party Offer, upon ten (10) days written notice to DBT, relocate the Option
Premises to other locations within the Building provided, however, that the
relocated Option Premises in each instance of relocation be: (a) the LESSER of
(i) not less than 50,000 contiguous square feet, or (ii) such remaining square
feet of Option Premises remaining following allowable exercises by DBT of its
Rights of First Refusal to lease less than all of the Option Premises, and (b)
be located in either 4560, 4660 or 4910 Blue Lake Drive. All references in this
Grant to the "Option Premises" shall include any space to which the Option
Premises has been relocated pursuant to the terms of this section 6.The term
Option Premises shall refer to any remaining reduced portions of the Option
Premises from time to time during the term of this Grant following DBT's
exercise, non-exercise of waivers of its Rights of First Refusal. In the event
that DBT elects to lease the Option Premises in response to a ten (10) day
relocation notice from Blue Lake not triggered or accompanied by a Third Party
Offer, during the pendency of the Option periods (i.e., from the Effective Date
of this Grant through and including June 30,1999) the Commencement Date for the
lease of the Option Premises shall be five (5) days following the date of the
election by DBT and shall be on the terms contained in Section 3.4 hereinabove.

the Free Rent periods provided for in Sections 1.B.(i)(c) and 1.B.(iii) of the
