pay any increase due over the estimated expenses paid and conversely any
overpayment made in the event said expenses decrease, shall be immediately
rebated by Lessor to Lessee.

Premises or any part thereof without the prior written consent of Lessor and any
alterations, additions or improvements to or on the Premises, except movable
furniture and trade fixtures, shall at once become a part of the realty and

the Lessee or anyone claiming under the Lessee, and that no mechanic's or other
liens for any such work, labor or materials shall attach to or affect the estate

mechanic's lien. Upon the expiration or sooner termination of the term hereof,

improvements designated by Lessor to be removed and repair any damage to the
Premises caused by such removal.

shall be given full opportunity to inspect and examine the Premises and, by
entry hereunder, Lessee accepts and acknowledges the Premises as being in good
order, condition and repair. Lessee shall, at Lessee's sole cost and expense,

           The Lessee shall enter into a Maintenance Contract with a Licensed
Air Conditioning Contractor for monthly preventative maintenance, including
change of air filters and clearing the condensation lines of all debris and any
mold or algae growth. In consideration of Lessee contracting for this service,
the Lessor will guarantee reimbursement to the Lessee for the replacement of any
faulty compressor and/or fan motor at Lessor's cost.

           10. ABANDONMENT. Lessee shall not vacate or abandon the premises at
any time prior to the expiration or earlier termination of the term hereof. In
the event Lessee shall abandon, vacate or surrender the Premises, or be
dispossessed by process of law, or otherwise, any personal property belonging to
Lessee and left on the Premises shall be deemed to have been abandoned. The
absence of Lessee for a period of thirty (30) consecutive days during the term
of this Lease shall automatically be deemed an abandonment of the Premises, but
such period of absence shall not be the exclusive test for a determination that
Lessee has vacated or abandoned the Premises if it may be determined that Lessee
has permanently abandoned the Premises even though Lessee has not been absent
from the Premises for thirty (30) consecutive days.

           11. LIENS. Notice is hereby given that the Lessor shall not be liable
for any work, labor, or materials furnished or to be furnished upon credit to or
for the Lessee or anyone claiming under the Lessee, and that no mechanic's or
other liens for any such work, labor or materials shall attach to or affect the
estate or interest of the Lessor in and to the Premises. The Lessee shall not do
or suffer anything to be done whereby the Premises may be encumbered by any
mechanic's lien.

           12. ASSIGNMENT AND SUBLETTING. Neither Lessee nor anyone claiming by,
through or under Lessee shall assign, transfer, mortgage, pledge, hypothecate or
encumber this Lease, or any interest therein, nor sublet the Premises or any
part thereof, or any right or privilege appurtenant thereto, or permit any other
person (the agents and employees of Lessee excepted) to occupy or use the
Premises, or any part thereof, without the prior written consent of Lessor,
which will not be unreasonably withheld. Upon any assignment or subletting,
voluntary or involuntary, Lessee named under this Lease shall pay any costs
incurred by Lessor to Lessor as a result of assignment or subletting of this
Lease, including, but not limited to, attorneys' fees and commissions. A consent
to one assignment, subletting, occupation or use by any other person shall not
be deemed a consent to any subsequent assignment, subletting, occupation or use
by any other person and no such assignment, subletting, occupation or use shall
relieve Lessee of any liability or obligation hereunder. Any such assignment or
subletting without such consent shall be voidable at the sole discretion of
Lessor and in any event shall constitute a default of Lessee under this Lease.
In the event of any assignment or subletting, the assignee or sub-Lessee shall
be bound by the terms hereof and Lessor may, after default by Lessee in the
payment of rent (including additional rent) or any other sum payable hereunder,
or any part thereof, collect such amount from such assignee or sublease without
first instituting legal action against Lessee. In no event shall this Lease or
the prior written consent of Lessor or by voluntary or involuntary bankruptcy
proceedings or otherwise and in no event shall this Lease or any rights or
privileges hereunder be an asset of Lessee under any bankruptcy, insolvency or
reorganization proceedings.

           13. INDEMNIFICATION OF LESSOR; INSURANCE. Lessor shall not be liable
or answerable to Lessee or any other person, firm or corporation for any injury
or damage resulting from the condition of, or any defect in, the Premises unless
Lessor's negligence resulted in such injury or damage, or such injury or damages
arises out of (a)Lessor's failure to construct the building in accordance with
the requirements of this Lease, or (b) any other

                                    Page -7-
<PAGE>   8
breach of this Lease by Lessor. Lessee agrees to indemnify Lessor against, and
hold Lessor free and harmless from, any and all penalties, costs, and expenses
(including attorney's fees, claims and demands and causes of action) arising out
of or in connection with (a) any accident or other occurrence in or on the
Premises, when such injury or damage shall be caused in part or in whole by the
act, neglect, fault of or omission of any duty with respect to the same by
Lessee, its agents, servants, employees, invitees, permittees, customers,
clients or guests, (b) the condition of, or any defect in the Premises or any
part thereof or any improvements thereon, provided said condition or defect was
caused by Lessee's negligence, (c) the Lessee's misuse of the Premises, or (d)
any breach of this lease by Lessee.

           Lessee agrees to and shall at its own cost and expense procure and
maintain during the entire Lease term and any extensions thereof comprehensive
public liability insurance covering the Premises and their surrounding areas and
naming Lessor as an additional insured. The liability coverage under such
insurance shall not be less than One Million Dollars ($1,000,000.00) for injury
or death of one person in any one accident or occurrence, Three Million Dollars
($3,000,000.00) for injury or death of more than one person in any one accident
or occurrence, and Two Million Dollars ($2,000,000.00) for property damage.
Lessee shall provide Lessor with certificates of such insurance evidencing
Lessee's compliance. All policies of insurance shall also provide that such
insurance will not be canceled except after ten (10) days' written notice to
Lessor. The originals of all policies shall remain in possession of Lessee;
provided, however, that Lessor shall have the right to receive from Lessee, upon
written demand, a duplicate policy or policies of any or all policies. All
insurance policies procured shall be issued by a responsible company or
companies authorized to do business in the State of Florida. In no event shall
the limits of said policies be considered as limiting the liability of Lessee to
Lessor under the first section of this Paragraph 13.

           14. SUBROGATION. Lessee and Lessor agree that if during the term
hereof either of them shall carry insurance against loss or damage or upon any
property of either party located therein, such insurance shall contain, if
available without additional cost, a clause where the insurer waives its right
of subrogation, if any, against the other party hereto and its successors and
assigns.

           15. SERVICES. The Lessor hereby represents that at the time of the
execution of this Lease, sufficient water, electricity, telephone, sewage
facilities and garbage removal capability will be available to the Lessee, for
the Lessee's intended use of the Premises. It is expressly understood that it is
the Lessee's responsibility to make necessary applications with the proper
authority for required utility service to serve the Premises, and such
applications are to be filed in sufficient time to allow the utility company to
provide service to the Premises after the Certificate of Occupancy is issued.
All cash deposits as may be required by the utility companies are the
responsibility of the Lessee.

           The Lessee agrees and covenants to pay all utility charges,
including, but not limited to, water, gas, electricity, sewage and removal of
waste materials used on or arising from use of the Premises and to pay the same
monthly or as they shall become due.

           16. CORPORATE LESSEE. If Lessee is a corporation, Lessee shall, at
the time of the execution of this Lease, deliver to Lessor a certified
resolution of its board of directors authorizing the execution of this Lease on
behalf of Lessee; provided, however, if the President or any Vice-President of
Lessee executes this Lease, no certified resolution need be provided. Lessor
acknowledges that Lessee is a corporation the stock of which is publically
traded on the NASDAQ Exchange.

                                    Page -8-
<PAGE>   9
           17. HOLDING OVER WITH CONSENT. If Lessee holds possession of the
Premises after the term of this Lease with Lessor's consent in writing signed by
both parties, Lessee shall become a tenant from month-to-month upon the terms
herein specified at the rental rate in effect for the Building as of the
expiration of the term of this Lease, payable in advance on or before the first
(1st) day of each month. Lessee shall continue in possession until such tenancy
shall be terminated by either Lessor or Lessee giving written notice of
termination to the other party at least thirty (30) days prior to the effective
date of termination. Any holding over without written consent of Lessor will be
at twice the rent rate in effect at the time.

           18. ENTRY BY LESSOR. Lessor shall have the right to enter the
Premises after first providing twenty-four (24) hour prior notice (whether
written or oral) to Lessee at all reasonable times (where such entry will not
unreasonably disturb or interfere with Lessee's use of the Premises) to inspect
the same or to cure any default, provided any applicable grace, notice or cure
period has expired, to supply any service to be provided by Lessor hereunder,
and to submit the Premises to prospective purchasers, tenants or mortgagees, to
post notices of non-responsibility, always providing that the business of Lessee
shall not be interfered with unreasonably.

           For each of the aforesaid purposes, Lessor shall at all times have
and retain a key with which to unlock all of the doors upon the Premises,
excluding Lessee's vaults, and Lessor shall have the right to use any and all
means to open said doors in an emergency in order to obtain entry to the
Premises, and any entry to the Premises obtained by Lessor shall not under any
circumstances constitute forcible or unlawful entry into or a detainment of the
Premises or an eviction of Lessee from the Premises or any portion thereof.

           19. EVENT OF DEFAULT. In addition to any events defined elsewhere in
this Lease as constituting a default of Lessee, any of the following shall also
be considered an event of default of Lessee hereunder: (a) If Lessee shall fail
to pay rent (including additional rent) or any part thereof or any other sums
payable pursuant to this Lease on the date due hereunder whether or not the same
shall have be demanded and such default shall continue for a period of fifteen
(15) days after written notice thereof from Lessor to Lessee; (b) If Lessee
shall fail to perform its obligation under Section 27 herein; (c) If Lessee
shall fail to observe or perform any of the other covenants or agreements
contained in this Lease to be observed or performed by Lessee, but such failure,
if of a type that can be cured or corrected by Lessee, shall not be a default
unless such failure continues for thirty (30) days after written notice of
breach thereof is given by Lessor to Lessee or in the case of a default which by
its nature will take longer than thirty (30) days to cure or correct, Lessee
fails to commence curing or correcting such default within such thirty (30) day
notice period; (d) If Lessee shall become bankrupt, go into receivership, or
make an assignment for the benefit of creditors, or take or have taken against
Lessee any proceedings of any kind under any provision of the Federal Bankruptcy
Act, and in the case where such proceeding has been commenced against Lessee,
such proceeding is not discharged within sixty (60) days of the filing thereof;
(e) If Lessee shall abandon the Premises in violation of Section 10 above; or
(f) If this Lease or any estate of Lessee shall be in default with respect to
any other lease between Lessor and Lessee.

           20. REMEDIES OF LESSOR. In the event of any default by Lessee, then
Lessor, in addition to any other rights or remedies it may have by statute or
otherwise, including the right to take no action other than to sue for damages
or rental in default, shall have the immediate right of re-entry and may remove
all persons and property from the Premises. Such property may, but need not, be
removed and stored in a public warehouse or elsewhere at the cost of any for the
account of Lessee. Should Lessor elect to re-enter by giving notice of such
intention to Lessee, as herein provided, or should Lessor actually take
possession by physical act, pursuant

                                    Page -9-
<PAGE>   10
to legal proceedings or any notices provided by law, Lessor shall either
terminate this lease or may from time to time, without terminating this Lease,
attempt to re-let the Premises or any part thereof for the account of Lessee for
such term or terms (which may be for a term extending beyond the term of this
Lease) and at such rental or rentals payable to Lessor and upon such other terms
and conditions as Lessor in exercise of Lessor's sole discretion may deem
advisable with the right to make alterations and repairs to the Premises at
Lessee's expense for the purpose of such re-letting.

           If Lessor elects to re-enter and attempts to re-let, or does re-let,
the Premises, Lessee shall remain fully liable for all obligations of Lessee
under this Lease and Lessor may attempt to lease other space in the Building
prior to re-letting or attempting to re-let the Premises. Lessor shall give
notice of any re-letting without termination to Lessee and upon such re-letting
(a) Lessee shall be immediately liable for and shall pay to Lessor, as
additional rent and in addition to any other sums due hereunder, the costs and
expenses of such re-letting (including advertising costs, brokerage fees, any
reasonable attorneys' fees incurred and the cost of any alterations and repairs
incurred by Lessor), and shall also become immediately liable for and shall pay
to Lessor the amount, if any, by which the rent reserved in this Lease for the
period of such re-letting (up to but not beyond the term of this Lease) exceeds
the amount (as then determinable) agreed in such re-letting to be paid as rent
for the Premises for said period, or (b) at the option of Lessor given in the
notice of re-letting, rents received by Lessor from such re-letting shall be
applied to the payment of the costs and expenses of such re-letting (including
advertising costs, brokerage fees, any reasonable attorneys' fees incurred and
the costs incurred for alterations and repairs); second, to the payment of rent
and other charges due and unpaid hereunder; and the residue, if any shall be
held without interest to Lessee by Lessor and applied in payment of future rent
as the same may become due and payable hereunder. If Lessee has been credited
with any rent to be received by such re-letting under option (a) and such rents
shall not be promptly paid to Lessor by the new tenant, or if adjustments to
rent pursuant to this Lease cause an increase in the rent, or if the rent
received from such re-letting under option (b) during any month be less than
that to be paid during that month by Lessee hereunder, Lessee shall pay any
deficiency to Lessor. Such deficiency shall be calculated and paid monthly
arrears; if any such monthly payments are not made, Lessor may at any time
undertake legal proceedings to recover all such payments, whether one or more
payments are past due, and Lessee shall be liable for all attorney's fees of
Lessor in connection with attempts to recover said payments, whether or not
legal proceedings are commenced.

           No re-entry or taking possession of the Premises by Lessor shall be
construed as an election on Lessor's part to terminate this Lease unless a
written notice of such intention be given to Lessee or unless the termination
thereof be decreed by a court of competent jurisdiction. Notwithstanding any
re-letting or attempted re-letting without termination, Lessor may at any time
thereafter elect to terminate this Lease for such previous default. Should
Lessor at any time terminate this Lease for any default, in addition to any
other remedy Lessor may have, Lessor may recover from Lessee all damages Lessor
may incur by reason of such default, including the cost of recovering the
Premises (including attorneys' fees, court costs, and storage charges), the
amount of rental payments then in default, and the worth at the time of such
termination of the excess, if any, of the amount of rent and additional rent
reserved in this lease for the remainder of the stated term over the then
reasonable rental value of the Premises for the remainder of the stated term,
and any other amount necessary to compensate Lessor for all detriment
proximately caused by Lessee's failure to perform its obligations under this
Lease or which in the ordinary course of events would be likely to result
therefrom, all of which amounts shall be immediately due and payable from Lessee
to Lessor upon demand.

<PAGE>   11
           21. DAMAGE OR DESTRUCTION. Except as otherwise provided in this Lease
in the event the Premises are damaged by fire or other casualty covered by
Lessor's insurance, such damage shall be repaired by and at the expense of the
Lessor. Lessor shall commence such repair work within thirty (30) days of such
casualty and shall proceed with due diligence to complete such repairs. Unless
such damage was caused by Lessee or its agents or employees in violation of this
Lease, either party may terminate this Lease by written notice to the other if
Lessor is unable to complete such repairs within one hundred fifty (150) days of
such casualty for any reason whatsoever, including Force Majeure,
notwithstanding Lessor's exercise of due diligence to complete such repairs, or
if prior to commencement of such repair work Lessor determines in its reasonable
opinion that such required repairs can not be completed within one hundred fifty
(150) days of the casualty and so notifies Lessor within thirty (30) days after
such casualty. Until such repairs are completed, and except to the extent such
damage was caused by Lessee or its agents or employees in violation of this
Lease, the rent payable hereunder shall be abated in proportion to the portion
of the Premises which is rendered unusable by Lessee in the conduct of its
business.

           Lessor agrees to keep the Premises insured at all times against all
perils for which insurance is available under a special multi-peril policy,
including without limitation, fire and extended coverage insurance, for the
greater of the full insurable or replacement value of the Premises, with a
responsible insurance company authorized to do business in Florida. Lessor
hereby acknowledges that Lessee shall insure for all or a portion of perils for
which insurance would normally be available to cover Lessee's personal property,
inventory, liability and Lessor's interest. Lessee shall provide Lessor with
Certificate(s) of Insurance evidencing compliance with the foregoing
requirements and naming Lessor as a loss payee as Lessor's interest may appear.

           22. EMINENT DOMAIN. If at any time during the term of this Lease the
entire Premises or any part thereof shall be taken as a result of the exercise
of the power of eminent domain or by agreement in lieu thereof (a "taking"),
this Lease shall terminate as to the part so taken as of the date possession is
taken by the condemning authority.

           If all of any substantial portion of the Premises shall be taken,
Lessor may terminate this Lease, at its option, by giving Lessee written notice
of such termination within thirty (30) days of such taking. If all or a portion
of the Premises shall be taken and Lessee reasonably determines that such taking
materially affects Lessee's ability to use the remaining portion of the Premises
for the uses permitted under this lease, Lessee may terminate this Lease at its
option by giving Lessor written notice of such termination within thirty (30)
days of such taking. In either of the foregoing events, this lease shall
terminate upon the giving of such notice; provided, however, Lessee shall have
up to ninety (90) days after such notice to remove its equipment and other
personal property from, and to vacate, the Premises. If neither party terminates
this Lease pursuant to this paragraph, this Lease shall remain in full force and
effect except that the rent payable by Lessee hereunder shall be reduced on a
pro-rata basis.

           All awards for the taking shall be the property of the Lessor;
provided, however, Lessee shall have the right to claim and recover from the
condemning authority such compensation as may be separately awarded or
recoverable by Lessee for any damage to Lessee's business, for any cost or loss
in removing Lessee's merchandise, trade fixtures, equipment, and other personal
property, for the non-amortized balance of Lessee's improvements to the
Premises, if any, and for the value of the remaining portion of the term of this
Lease with respect to the portion of the Premises subject to the taking.

<PAGE>   12
           23. MORTGAGE REQUIREMENTS. This Lease is junior, subject, and
subordinate to all mortgages, deeds of trust, and other security instruments of
any kind (each of which is hereinafter referred to as a "mortgage") now covering
the Building and/or the property on which the Building is located or any portion
thereof. Lessor reserves the right to place liens or encumbrances on the
Building and/or the property on which the Building is located or any part
thereof superior in lien and effect to this Lease. This Lease, at the option of
Lessor, without the necessity for any notice to Lessee, shall be subject and
subordinate to any and all such liens and encumbrances now or hereafter imposed
by Lessor without the part of Lessee to effectuate such subordination.
Notwithstanding the foregoing, Lessee covenants and agrees to execute and
deliver upon demand such further instruments evidencing such subordination as
may be requested by Lessor.

           Lessee agrees that in the event any proceedings are brought for the
foreclosure of, or in the event of exercise of the power of sale under any
mortgage affecting the Premises, whether or not this Lease is terminated by such
foreclosure or sale, it will, upon request by the purchaser, attorn to the
purchaser under any such foreclosure or sale and recognize such purchaser as
Lessor under this lease.

           Lessee covenants upon not less than ten (10) days' prior written
notice by Lessor to execute, acknowledge and deliver to Lessor a statement in
writing certifying that this Lease is unmodified and in full force and effect
and that Lessee has no defenses, offsets or counterclaims against its
obligations to pay the rent and to perform its other covenants under this Lease
(or, if there have been any modifications that the same is in full force and
effect as modified and stating the modifications and, if there are any defenses,
offsets or counterclaims, setting them forth in reasonable detail), and the date
to which the rent has been paid. Any such statement delivered pursuant to this
Section may be relied upon by any prospective purchaser or mortgagee of the
Premises or any prospective assignee of any such mortgage.

           24. NOTICES. All notices, demands and statements which may or are
required to be given by either party to the other hereunder shall be in writing
and shall be personally delivered or sent by United States certified mail,

Either party may change its address by notice given to the other in the manner
set forth in this Section. Notices, demands and statements shall be deemed given
and received when personally delivered or two (2) days after they are mailed or
one (1) day after they are faxed as provided.

           25. LESSOR'S RIGHT TO CURE DEFAULTS. All covenants and agreements to
be performed by Lessee under any of the terms of this Lease shall be at its sole
cost and expense and, except as otherwise specifically provided herein, without
any abatement of rent. If Lessee shall fail to pay any sum of money, other than
rent, required to be paid by it hereunder or shall fail to perform any other act
on its part to be performed hereunder, then, upon expiration of any notice, cure
or grace period required elsewhere in this Lease for defaults, Lessor may, but
shall not be obligated so to do, and without waiving any rights of Lessor or
releasing Lessee from any obligations of Lessee hereunder, make such payment or
perform such other act. All sums so paid or expenses incurred by Lessor and all
necessary incidental costs together with interest thereon at the rate of twelve
percent (12%) per annum from the date of such payment by Lessor shall be
considered as rent owing hereunder and shall be payable to Lessor on demand or,
at the option of Lessor, may be added to any rent then due or thereafter
becoming due under this Lease. In addition, Lessor shall have the same rights
and remedies in the event of the non-payment thereof by Lessee as in the case of
default by Lessee in the payment of any rent hereunder.

           26. DELAYS; DEFAULT BY LESSOR. Except as otherwise provided in this
Lease, neither Lessee or Lessor shall not be responsible for any delay or
failure in the observance or performance of any term of condition of this Lease
to be observed or performed by Lessor or Lessee, as the case may be, to the
extent that such delay results from action or order of governmental authorities;
civil commotion; strikes, fires, acts of God or the public enemy; inability to
procure labor, material, fuel, electricity, or other forms of energy; or any
other cause beyond the reasonable control of Lessor or Lessee, as the case may
be, whether or not similar to the matter herein specifically enumerated. Except
as otherwise provided in this Lease, any delay shall extend by like time any
period of performance by Lessor or Lessee, as the case may be, and shall not be
deemed a breach of or failure to perform this Lease or any provisions hereof.

           In the event of any default under this Lease by Lessor, Lessee,
before exercising any rights that it may have at law to cancel this Lease, shall
have given notice of such default to Lessor and Lessor shall have thirty (30)
days from such notice to cure such default, or in the case of a default which by
its nature cannot be cured within such thirty (30) days, Lessor shall have
thirty (30) days to commence curing or correcting such default provided Lessor
continues to pursue such corrective action until the default is cured. Lessee
also agrees to give the holders of any mortgages or deeds of trust ("mortgages")
by certified mail, a copy of any notice of default served upon Lessor, provided
that prior to such notice Lessee has been notified in writing (by way of Notice
of Assignment of Rents and Leases, or otherwise) of the addresses of such
mortgagees. Lessee further agrees that if Lessor shall have failed to cure such
default within the aforesaid time limit, then the mortgagees shall have an
additional thirty (30) days within which to cure such default or if such default
cannot be cured with that time, then such additional time as may be necessary if
within such thirty (30) days any mortgages has commenced and is diligently
pursuing the remedies necessary to cure such default (including but not limited
to commencement of foreclosure proceedings if necessary to effect such cure), in
which event this Lease shall not be terminated while such remedies are being so
diligently pursued.

<PAGE>   14
           27. TRANSFER OF LESSOR'S INTEREST. In the event Lessor transfers its
reversionary interest in the Premises (other than a transfer for security
purposes only), Lessor shall be relieved of all obligations accruing hereunder
after the effective date of such transfer, including, but not limited to, the
return of the security deposits or other funds held by Lessor, provided that
such obligations have been expressly assumed in writing by the transferee, and
Lessee agrees to attorn to the transferee.

           Lessee agrees at any time and from time to time to at the request of
Lessor, to execute, acknowledge and deliver to Lessor within ten (10) days from
the date of said request a statement in writing certifying that this Lease is
unmodified and in full force and effect (or if there have been modifications,
that the same is in full force and effect as modified and stating the
modifications or if there are any defenses, offsets or counterclaims, setting
them forth in reasonable detail), and the dates to which the fixed rent and
other charges have been paid in advance, if any, it being intended that any such
statement delivered pursuant to this paragraph may be relied upon by any
prospective purchaser, mortgagee or assignee of any mortgage on the Premises.

           28.  SECURITY DEPOSIT.  Lessor has waived any security deposit.

           29. SUCCESSOR AND ASSIGNS. Subject to all limitations on assignment
and subletting set forth herein, all of the terms and provisions of this Lease
shall inure to the benefit of and be binding upon the heirs, devisees, legal and
personal representatives, successors and assigns of each of the parties hereto.

           30. ATTORNEYS' FEES. In the event of any action or proceeding to
compel compliance with or for a breach of the terms and conditions of this
lease, the prevailing party shall be entitled to recover from the losing party
all costs and expenses of such action or proceeding, including, but not limited
to attorneys' fees of the prevailing party in such amount as the court may
adjudge reasonable.

           31. SURRENDER OF PREMISES. The voluntary or other surrender of this
Lease by Lessee, or a mutual cancellation thereof, shall not work a merger, and
shall, at the option of Lessor, terminate all or any existing sub-tenancies, or
may, at the option of Lessor, operate as an assignment to it of any or all such
sub-tenancies.

           32. INTEREST ON PAST DUE OBLIGATIONS. Except as otherwise provided in
Section 38, any amount due to Lessor not paid when due shall bear interest at
the rate of twelve percent (12%) per annum from default. Payment of such
interest shall not excuse or cure any default by Lessee under this Lease.

           33. WAIVER. No waiver of any term, covenant, condition or obligation
of this Lease, or any breach thereof, shall be effective unless granted in
writing. The waiver by Lessor or Lessee of any term, covenant, condition or
obligation herein contained or of any other breach thereof shall not be deemed
to be a waiver of any other term, covenant, condition or obligation or of any
other breach of the same or other term, covenant, condition or obligation herein
contained. The subsequent acceptance of rent hereunder by Lessor shall not
constitute a waiver of any preceding breach by Lessee, regardless of Lessor's
knowledge of such preceding breach at the time of acceptance of such rent.

           34. CONSTRUCTION. This Lease shall be governed by and construed in
accordance with Florida law, and the invalidity of unenforceable provisions of
this Lease shall not affect or impair the validity of any other provision
hereof.

<PAGE>   15
           35. DEFINITIONS AND HEADINGS. The term "Lessor" and "Lessee" as used
herein shall include the plural as well as the singular and shall include the
masculine, feminine and neuter. If there is more than one Lessor, the
obligations of Lessor hereunder shall be joint and several. Paragraph headings
in this Lease are for convenience only and shall not define or limit the scope
or intent of any provision hereof.

           36. TIME OF ESSENCE. Time is of the essence of this Lease and of each
provision hereof. Lessee hereby acknowledges that late payment by Lessee to
Lessor of rent or other sums due hereunder will cause Lessor to incur costs not
contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges and delinquency reports to lien holders. Accordingly, if
any installment of rent or any sum due from Lessee shall not be received by
Lessor within ten (10) business days after said amount is due, then Lessee shall
pay to Lessor four percent (4%) of the amount due as liquidated damages, plus
any attorneys' fees incurred by Lessor by reason of Lessee's failure to pay rent
and/or other charges when due hereunder. Acceptance of such amounts by Lessor
shall in no event constitute a waiver of Lessee's default with respect to such
overdue amount, nor prevent Lessor from exercising any of the other rights and
remedies granted under this Lease.

           37. ENVIRONMENTAL COMPLIANCE. Lessor further warrants that the
Premises is in environmental compliance with all Environmental Laws, and there
is no contamination that exists on the Premises that would result in liability
to Lessee.

           38. HAZARDOUS WASTE. Lessee agrees to comply strictly and in all
respects with the requirements of any and all federal, state and local statutes,
rules and regulations now or hereinafter existing relating to the discharge,
spillage, storage, uncontrolled loss, seepage, filtration, disposal, removal or
use of hazardous materials, including but not limited to the Comprehensive
Environmental Response, Conservation and Liability Act of 1980, the Superfund
Amendments and Re-authorization Act, the Resource Conservation and Recovery Act,
the Hazardous Materials Transportation Act and the Florida Substances Law
(collectively the "Hazardous Waste Law").

           39. RADON GAS. Pursuant to Florida Statutes, Section 404.056(8) every
prospective purchaser of any building and every prospective Lessee of any
building is hereby notified prior to or at the time of execution of a Contract
for Sale and Purchase or the execution of a Rental Agreement for any building of
the following: "RADON GAS: Radon is a naturally occurring radioactive gas that
when it has accumulated in a building in sufficient quantities, may present
health risks to persons who are exposed to it over time. Levels of radon that
exceed federal and state guidelines have been found in buildings in Florida.
Additional information regarding radon and radon testing may be obtained from
your county public health unit."

           40. WAIVER OF JURY TRIAL. Each party by execution hereof knowingly,
voluntarily, and intentionally waives, for themselves and their respective
heirs, successors, and assigns, any right any one of them may have to a trial by
jury in respect to any litigation, action, suit or proceeding (whether at law or
in equity) based on this Lease or any other documents arising out of, under, or
in connection with any of the foregoing, or any course of conduct, course of
dealing (whether verbal or written) or action of any party or their respective
officers, principals, partners, employees, agents, or representatives in
connection with or in respect to the

                                   Page -15-
<PAGE>   16
Premises, whether arising in contract, tort, or otherwise and whether asserted
by way of complaint, answer, cross-claim, counterclaim, affirmative defense, or
otherwise. No party shall seek to consolidate any such litigation, action, suit
or proceeding in which a jury trial cannot be or has not been waived with any
other action in which a jury trial has been waived. This provision is a material
inducement to Lessor and Lessee to enter into and perform this Lease.

           41. SIGNAGE. Lessee shall have the right, at Lessor's expense, to
erect directional and informational sign(s) on the exterior and/or interior of
the building as Lessee shall deem necessary and appropriate. Said sign(s) may be
replaced from time to time in Lessee's discretion at Lessor's expense.

           42. TAX GRIEVANCE. Lessee shall have the right at Lessee's expense at
any time during the term of this Lease to institute a proceeding at the local
taxing authority to have the real estate taxes attributable to the Premises
reduced. Lessor shall cooperate with Lessee in all such proceedings, including
but not limited to signing any and all documents and if necessary bringing the
proceeding in Lessor's name. In the event Lessee is successful in any such
proceeding and Lessor should receive any refund from the local taxing authority,
said refund shall immediately be paid over to the Lessee in the event that said
refund covers a period during which Lessee was paying said taxes.

           43. COVENANT OF QUIET ENJOYMENT. Lessor covenants and agrees that so
long as Lessee shall be in possession of the Premises under this Lease, and
shall pay the rent as herein provided, and shall comply with the terms and
conditions of this Lease on the Lessee's part to be performed hereunder, Lessee
shall be entitled to peaceably enjoy possession of the Premises without undue
interference from the Lessor or any other lessee(s) in the building.

           44. REAL ESTATE BROKERS COMMISSION. The parties hereto agree that
Hailey Realty Company brought about the execution of this Lease and Lessor shall
be responsible to pay Hailey Realty Company a commission pursuant to a separate
agreement between Lessor and Hailey Realty Company.

           45.   RIGHT OF FIRST REFUSAL.

           A. ADDITIONAL SPACE OF LEASE: Provided Lessee shall have throughout
the term of this Lease, fully performed all of its obligations under this Lease,
and has not defaulted herein, and further provided, that during the term of this
Lease any additional space at or near the Premises becomes available for lease,
Lessor shall before offering same on the market, first offer same to the Lessee
upon the same rent, terms and conditions as Lessor shall offer to any third
party.

           Lessee shall have twenty (20) business days immediately following
receipt of written notification from Lessor of the availability of such space
for lease to notify Lessor in writing by certified mail with return receipt
requested or by overnight courier that Lessee has agreed to lease such
additional space upon the terms and conditions as set forth by Lessor.

           In the event Lessee has notified Lessor of its intention to exercise
its option to lease the additional space as provided herein, Lessor will deliver

and conditions as agreed upon between the parties.

term of this Lease, fully performed all of its obligations under this Lease, and
has not defaulted herein, and further provided, that during the term of this
Lease the Building becomes available for purchase, Lessor shall before offering
same on the market, first offer same to the Lessee upon the same purchase price,

incorporating the terms and conditions as agreed upon between the parties. 46.

5.3 parking spaces for every 1000 square feet that Lessee shall rent pursuant to
the terms herein. Said number of spaces shall adjust in accordance with any
adjustment in square footage rented.

           47. RECORDING. The Lessee agrees that it will not record this Lease
in any government facility and in the event the Lessee should record this Lease,
then said recording will serve to automatically cancel this Lease.

           48. ENTIRE AGREEMENT. This Lease, the Exhibits, and any agenda
attached hereto and executed by the parties, constitute the entire agreement of
the parties and supersede all prior agreements or understanding between the
parties with respect to the subject matter hereof. This Lease may not be

           IN WITNESS WHEREOF, the parties hereto have hereunto set their hands
and seals, the day and year first above written.

                       LEGAL DESCRIPTION OF REAL PROPERTY
                              (Volusia Plaza Site)

(This exhibit shall contain the exact description of the leased premises when
received from the architect or engineer and then become part of this Lease.)

                                    EXHIBIT B
                        CONSTRUCTION TERMS AND CONDITIONS

           1. Construction: Lessor shall construct, or cause to be constructed,
at Lessor's cost and expense and at no cost or expense to Lessee, the building
and other improvements (collectively the "Improvements") to the Premises in
accordance the Plans (hereinafter defined), all applicable governmental laws,
ordinances and regulations (the "Laws") and this Lease, and in connection
therewith, Lessor shall (a) promptly and diligently furnish, or cause to be
furnished, all materials and perform, or cause to be performed, all work
necessary to construct the Improvements and improve the Premises in accordance
with the Plans, all in good workman like manner and in accordance with best
trade practices and in compliance with the Laws and this Lease, (b) obtain and
pay for all required governmental permits and approvals (the "Governmental
Approvals") required for construction of the Improvements and occupancy and use
of same by Lessee for the uses permitted under this Lease and (c) install and
connect all requisite sewer, water, electrical, and drainage facilities required
for the Premises and its use by Lessee as permitted under this Lease after
completion, and pay all connection fees therefore (which utility facilities are
to be considered part of the "Improvements" as such term is used herein). Lessor
has employed T.G. Glass & Associates, Inc. ("Contractor") to provide and perform
all architectural, engineering and contracting services required for the
construction of the Improvements. Lessor has the right to use any other
contractor to perform such services for construction of the Improvements with
approval of Lessee, which approval will not be unreasonably withheld.

           2. Plans: Lessor shall contract an engineer, architect and general
contractor to prepare final plans and specifications for the Improvements based
upon Lessee's input. Upon completion of the final plans and specifications for
the Improvements and approval of same by Lessor and Lessee each having initialed
each page of same, such plans and specifications (the "Plans") shall be deemed a
part of this Lease as if attached hereto even if not physically attached hereto.
In the event final plans and specifications have not been so approved by both
Lessor and Lessee on or before March 5, 2001 (the "Approval Date"), Lessor and
Lessee shall each have the right to cancel this Lease by written notice to the
other any time thereafter unless and until plans and specifications have been so
approved by both parties. If the Plans are approved after the approval date,
permit date, completion date, commencement date and termination date shall each
be extended by the same number of days unless the parties agree otherwise in
writing.

                                   Page -19-
<PAGE>   20
           3. Governmental Approvals: Upon approval of the Plans by both
parties, Lessor shall promptly submit the Plans to all appropriate governmental
authorities and diligently seek to obtain the Governmental Approvals on or
before the permit date, as the same may be extended by agreement of the parties.
In the event Lessor has not obtained the Governmental Approvals and commenced
work within ten (10) days of the permit date (as the same may be extended by
agreement only) for any reason whatsoever, including Force Majeure, Lessee may
at its option terminate this Lease. Upon such termination the security deposit
paid to Lessor by Lessee pursuant to this Lease shall be returned to Lessee.

           4. Completion: Lessor shall complete the construction of the
Improvements and provide Lessee with the notice of completion and a copy of the
Certificate of Occupancy or other official notice from the appropriate
governmental agency indicating the building constructed was completed pursuant
to all required governmental laws and regulations and can be fully occupied for
the use(s) intended herein (the "Completion Notice"). The completion date may be
extended by agreement or changes to the Plans agreed upon as provided below,
subject, however, to delays caused by Force Majeure as defined in Section 26 of
this Lease. Lessor's construction obligations under this Lease shall be
considered completed upon (a) completion of construction of the Improvements in
accordance with the Plans, the Laws, and this Lease, and (b) upon Lessor having
delivered the Completion Notice to Lessee. Lessor shall deliver possession of
the Premises to Lessee, and Lessee shall accept delivery of possession of the
Premises from Lessor, upon such completion by Lessor of its construction
obligation under this Lease (including Lessor having delivered the Completion
Notice to Lessee). Notwithstanding anything in this Lease to the contrary, in
the event such construction obligations are not completed, the Completion Notice
is not given and possession delivered to Lessee by a) September 15, 2001, then
Lessor shall pay all costs, expenses and penalties incurred by Lessee, including
but not limited, all additional rent and other charges imposed by Lessee's
current Landlord, for each day thereafter until two weeks after the Completion
Notice is delivered to Lessee; and b) by November 15th, 2001 (as the same may be
extended by agreement only) for any reason whatsoever, including Force Majeure,
then Lessee may at its option terminate this Lease unless delay of possession
was caused by Lessee. Upon such termination the Security Deposit paid to Lessor
by Lessee pursuant to this Lease shall be returned to Lessee.

           The Completion Notice shall include copies of all required
Governmental Approvals, including a Certificate of Occupancy, required for (and
permitting) occupancy and use of the Premises by Lessee for uses under this
Lease, and a certificate by Lessor's Contractor or by its engineer certifying
that all Lessor's construction obligations under this Lease have been
substantially completed in accordance with the Plans and the Laws.

           5. Change Orders. All changes, omissions, or additions to the Plans
shall be made only by written change order or other amendment duly signed by the
parties hereto (signers of this Lease). Any such written change order amendment
shall extend the Completion Date, as agreed to by the contractor's time estimate
for the change made to construct said change order.

           6. Lessee Inspections. Lessor shall allow Lessee to review and
inspect all material and work at all times and shall, after receiving written
notice from Lessee of defective work and/or materials, whether complete or
incomplete, proceed to remove all such defective work and materials and replace
same at Lessor's expense.

           7. Warranties. Lessor shall provide Lessee with copies of all
warranties of the Contractor and all other contractors, sub-contractors,
manufacturers and suppliers of equipment used in connection with construction of
the Improvements. Lessor shall at Lessee's request enforce such warranties with
respect to any portion of the Improvements (including fixtures and other
equipment) for which Lessee has repair obligations under this Lease. Such
warranties shall not relieve Lessor of its obligations under this Lease.

           8. Time of Essence. Time is of the essence as to the provisions of
this Exhibit B.

         7.   Subordination.

              7.1 Subordination Agreement. The Borrower, for itself, its

against the Borrower or against the Holder of this Note without joining the
Borrower as a party. The Holder acknowledges that the creation and existence of
Senior Indebtedness shall not constitute a default under or contravene any
provision of this Note. The Holder shall execute and deliver to any holder or

other instruments as may be requested by the holder or holders of Senior
Indebtedness or their representatives to enforce all claims upon or in respect

principal of, premium or interest on, or other amounts due with respect to this
Note shall be made, during a single continuous period of 179 days (the

declaring the commencement of the Standstill Period as a result of (i) there
having occurred a default in any payment of principal of, premium or interest
on, or fees or other expenses incurred to the holders of the Designated Senior
Indebtedness with respect to, any Designated Senior Indebtedness beyond any
applicable grace period with respect thereto, or (ii) there having occurred an
event of default (other than a default in the payment of amounts due thereon)
with respect to any Designated Senior Indebtedness, as defined in the instrument
under which the same is outstanding, beyond any applicable grace period with
respect thereto, permitting the holders thereof to accelerate the maturity
thereof, and such event of default shall not have been cured or waived or shall
not have ceased to exist and (y) ending on the earliest of (i) 179 days
following the commencement of such period, (ii) the date on which all such
defaults and events of default are cured, waived or cease to exist, (iii) the

discharged or (iv) the date on which the Standstill Period shall have been
terminated in writing by the Designated Representative, after which the Borrower
shall promptly resume making any and all required payments in respect of this
Note, including any missed payments. In the event that notwithstanding the
provisions of this Section 7.3, the Borrower shall during the Standstill Period
make any payment of principal of, interest on, or other amounts due with respect
to this Note to the Holder after receipt by the Holder of written notice from
the Designated Representative of the commencement of the Standstill Period, then
such payment shall be held by the Holder in trust for the benefit of, and shall
be paid forthwith over and delivered to, the holders of Senior Indebtedness (pro
rata as to each of such holders on the basis of the respective amounts of Senior
Indebtedness held by them after due written notice of the names of such holders
and the respective amount of the indebtedness held by such holders) or their
representative or representatives, for application to the payment of all Senior
Indebtedness remaining unpaid, to the extent necessary to pay all Senior
Indebtedness remaining unpaid in full in accordance with the terms of such
Senior Indebtedness after giving effect to any concurrent payment or

defining the relative rights of the holders of such Senior Indebtedness, on the
one hand, and the Holder, on the other hand.

have been entitled but for the provisions of this Section 7 shall have been
applied, pursuant to the provisions of this Section 7, to the payment of amounts
payable under the Senior Indebtedness, then and in such case the Holder shall be
entitled to receive from the holders of such Senior Indebtedness at the time

ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Borrower, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Section 7. The failure
to make a payment of principal of or interest on, or other amounts due under,
