                              AMENDED AND RESTATED
                   AGREEMENT OF COMMITMENT TO EXERCISE RIGHTS

and O. F. Ramos ("Ramos"), L. A. Gornto, Jr. ("Gornto"), Bernard B. Markey
("Markey"), William Knox North ("North"), Edward S. Jordan ("Jordan") and
Edward A. Moses ("Moses") (each of Ramos, Gornto, Markey, North, Jordan and
Moses a "Purchaser" and collectively the "Purchasers").

                                   RECITALS:

         WHEREAS, the Company proposes to issue rights to purchase its common
stock, par value $.0001 per share (the "Common Stock"), pursuant to a

Commission in December 1999 (the "Rights Offering"); and

         WHEREAS, the Company and the Purchasers entered into that certain
Agreement of Commitment to Exercise Rights, dated as of December 21, 1999 (the
"Commitment Agreement"); and

         WHEREAS, the Purchasers will be issued rights pursuant to the Rights
Offering; and

         WHEREAS, the Company and the Purchasers desire to amend and restate
the Commitment Agreement to clarify, among other things, that the Common Stock

registered as part of the Rights Offering and will be issued pursuant to an
exemption from registration provided by Section 4(2) of the Securities Act of
1933, as amended (the "Securities Act").

                  ---------             ----------------------

                  Ramos                 407,424 shares

         3.       Mechanics of Payment for Shares.

                  (a) With respect to the shares acquired under subsections
2(a) and (b), above, the Purchasers shall exercise and pay for such shares in
accordance with the terms of the Rights Offering.

                  (b) With respect to the purchase of Additional Shares under
Section 2(b), above, on the Closing Date, the Company shall notify the
applicable Purchasers of the number of Additional Shares that they are
obligated to purchase under subsections 2(b)(i), (ii) and (iii). Within three
(3) business days of such notice (which shall be transmitted by facsimile and
shall be deemed received on the date sent), the Purchasers acquiring Additional
Shares shall deliver the full amount of the subscription price to the Company
by wire (pursuant to wiring instructions provided by the Company) or other good
funding mechanism approved by the Company.

         4.       Representations and Warranties. Each Purchaser hereby
severally represents, warrants and covenants to the Company that, in connection
herewith:

                  (a) The Purchaser is an accredited investor as that term is
defined in Section 501(a) under Registration D promulgated by the Securities
and Exchange Commission under the Securities Act.

                  (b) Review and Evaluation of Information regarding the
Company. The Purchaser has had an opportunity to examine the governing
instruments and the material disclosure and other documents and records of the
Company. The Purchaser has had an opportunity to ask questions and receive
answers from the Company and from representatives of the Company concerning the
Company's financial condition and business and to obtain such other information
that he has deemed necessary to make a fully informed decision.

                  (c) Purchaser's Financial Experience. The Purchaser is
sufficiently experienced in financial and business matters to be capable of
evaluating the merits and risks of its/his investment in the Common Stock. The
Purchaser is familiar with the nature and risks attending investments.

                  (d) Suitability of Investment. The Purchaser understands that
the shares of Common Stock are speculative investments and involve a high
degree of risk, including but not limited to: there is no guarantee of success
of the business of the Company; he may not receive any return (economic or
otherwise) on his investment, and management and the majority shareholders of
the Company have extreme latitude and generally, the sole discretion, to
determine the financial picture, operations and potential dissolution of the
Company. The Purchaser has evaluated the merits and risks of the Purchaser's
proposed investment in the Common Stock, including those risks particular to
the Purchaser's personal situation, and he has determined that this investment
is suitable for the Purchaser. The Purchaser has adequate financial resources
for an investment of this character, and, at this time, the Purchaser could
bear a complete loss of his investment. Further, the Purchaser will continue to
have, after making his investment in the Common Stock, adequate means of
providing for his current needs, the needs of those dependent on him, and
possible personal contingencies.

                                      -3-
<PAGE>   4

                  (e) Investment Intent. The Purchaser is purchasing the Common
Stock for investment purposes only and for his own account, and has no present
commitment, agreement or intention to sell, distribute or otherwise dispose of
any of them or to enter into any such commitment or agreement.

                  (f) No Public Market for the Common Stock. The Purchaser
understands that there is currently no public market for the Common Stock and
that even if a public market were to exist, there is no certainty that a public
market could be sustained or that the Common Stock could be easily liquidated.

                  (g) Rule 144. The Purchaser understands that he is an
"affiliate" of the Company as such term is defined in Rule 144 promulgated
under the Securities Act. The Purchaser also understands that the Common Stock
acquired by Purchaser will not be registered in the Rights Offering and for
resale purposes will be subject to the requirements and restrictions of Rule
144. Purchaser is familiar with Rule 144, promulgated under the Securities Act,
which, in substance, permits limited public sale of "restricted securities"
acquired, directly or indirectly from the issuer thereof, in a nonpublic
offering, subject to the satisfaction of certain conditions. Rule 144 requires,
among other things: (1) that the resale occur not less than one year after the
party has purchased, and made full payment for, within the meaning of Rule 144,
the securities to be sold; and, in the case of an affiliate, or of a
nonaffiliate who has held the securities less than two years, (2) the
availability of certain public information about the Company, (3) the sale must
be made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as that term is defined under the
Exchange Act), and (4) the amount of securities being sold during any three
month period must not exceed the greater of (i) one percent (1%) of the then
issued and outstanding common stock of the Company or (ii) the average trading
volume of the common stock of the Company during the four weeks immediately
preceding the proposed sale.

                  (h) Non-Reliance Regarding Tax Consequences. The Purchaser is
not relying on the Company or any representation contained herein with respect
to the tax or economic effect of his investment in the Common Stock. The
Purchaser has reviewed with the Purchaser's own tax advisors the federal,
state, local and foreign tax consequences of this investment and the
transactions contemplated by this Agreement. The Purchaser is relying solely on
such advisors and not on any statements or representations of the Company or
any of its representatives. The Purchaser understands that he shall be
responsible for the Purchaser's own tax liability that may arise as a result of
this investment or the transactions contemplated by this Agreement. The
Purchaser understands that Section 83 of the Internal Revenue Code of 1986, as
amended (the "Code"), taxes as ordinary income the difference between the
purchase price for the Common Stock and the fair market value of the Common
Stock as of the date any restrictions on the Common Stock lapse.

                  (i) Prohibitions on Cancellation, Termination, Revocation,
Transferability, and Assignment. The Purchaser hereby acknowledges and agrees
that, except as may be specifically provided herein or by applicable law, he is
not entitled to cancel, terminate, or revoke this Agreement. The Purchaser
further agrees that he may not transfer or assign its rights or obligations
under this Agreement without the written consent of the Company.

                  (j) Authority to Enter into Agreement. The Purchaser has the
full right, power and authority to execute and deliver this Agreement and
perform his obligations hereunder, and when executed and delivered, this
Agreement will constitute a valid and legally binding obligation of such
Purchaser.

                  (k) Legends. Each certificate representing the Common Stock
may be endorsed with the following legends:

                      The securities represented by this certificate have been
                      acquired for investment and have not been registered
                      under the Securities Act of 1933, as amended, or
                      qualified under the laws of any state. Such shares may
                      not be sold or transferred in the absence of such
                      registration or such qualification unless the transfer is
                      in accordance with Rule 144 or similar rule or unless the
                      corporation receives an opinion of counsel reasonably
                      acceptable to it stating that such sale or transfer is
                      exempt from the registration and prospectus delivery
                      requirements of said act and any applicable state
                      securities laws. Copies of the agreement covering the
                      purchase of these shares and restricting their transfer
                      may be obtained at no cost by written request made by the
                      holder of record of this certificate to the secretary of
                      the corporation at the principal executive offices of the
                      corporation.

effect at the commencement of the term of this Lease.

         Section 8.02 If, by reason of any failure of Tenant to comply with the
provisions of this Lease, rate of fire, boiler, sprinkler, water damage or
other insurance (with extended coverage) on the Building, or on the property
and equipment of Landlord or any other tenant or subtenant in the Building,
shall be higher than it otherwise would be, Tenant shall reimburse Landlord and
the other tenants or subtenants in the Building which shall have been charged
because of such failure by Tenant, and Tenant shall make the reimbursement on
the first day of the month following such payment by Landlord or such other
tenants or subtenants. In any action or proceeding wherein Landlord and Tenant

         Section 8.04 All such insurance shall be effected under valid and
enforceable policies (which may cover the Demised Premises and other
locations); shall be issued by insurers of

                                     - 5 -

and shall contain a provision whereby the insurer agrees not to cancel the
insurance without ten (10) days' prior written notice to Landlord.

         Section 8.05 On or before the Commencement Date, Tenant shall furnish
Landlord with a certificate evidencing the aforesaid insurance coverage,

by Tenant. However, if such partial damage is due to the fault or neglect of
Tenant, Tenant's servants, employees, agents, visitors or licensees, without
prejudice to any other rights and remedies of Landlord and without prejudice to
the rights of subrogation of Landlord's insurer, the damages shall be repaired
by Landlord but there shall be no appointment or abatement of rent. No penalty
shall accrue for reasonable delay which may arise by reason of adjustment of
insurance on the part of Landlord and for reasonable delay on account of "labor
troubles", or any other cause beyond Landlord's control. Tenant shall give
immediate notice to Landlord in case of fire in the Demised Premises.
Notwithstanding the foregoing, if the Demised Premises are totally or
substantially damaged or are rendered wholly or substantially untenantable by

shall be so damaged that Landlord shall decide to demolish it or to rebuild it
(whether or not the Demised Premises have been damaged), then, or in any of
such events, Landlord may, within ninety (90) days after such fire or other
cause, give Tenant a notice in writing of such decision (which notice shall be
given as in Article 29 hereof provided), and thereupon the term of this Lease
shall expire by lapse of time upon the third day after such notice is given,
and Tenant shall vacate the Demised Premises and surrender the same to
Landlord. If Tenant shall not be in default under this Lease, then upon the
termination of this Lease under the conditions provided for in the sentence
immediately preceding, Tenant's liability for rent shall cease as of the day
following the casualty. If the damage or destruction be due to the fault or
neglect of Tenant, the debris shall be removed by, and at the expense of,
Tenant and, if Tenant shall fail to remove same, such removal may be done by
Landlord at the expense of Tenant.

         Section 9.02 No damages, compensation or claims shall be payable by
Landlord for inconvenience, loss of business or annoyance arising from any
repair or restoration of any portion of the Demised Premises or of the
Building. Landlord shall use its best efforts to effect

                                     - 6 -
<PAGE>   10

such repairs promptly and in such manner as not unreasonably to interfere with
Tenant's occupancy.

observed, performed or complied with.

         Section 10.03 Tenant agrees that its sole remedies in cases where
Landlord's reasonableness in exercising its judgment or withholding its consent
or approval is applicable and in issue shall be only those in the nature of an
action for an injunction or specific performance, the right to money damages or
other remedies being hereby specifically waived.

         Section 10.04 Tenant shall give immediate notice to Landlord in case
of accidents in the Demised Premises or in the Building or of defects therein
or in any fixtures or equipment.

         Tenant shall not move any safe, heavy equipment or bulky matter in or
out of the Building without Landlord's prior written consent, which consent
Landlord agrees not to unreasonably withhold. If the movement of such items
requires special handling, Tenant agrees to employ only persons holding a
Master Riggers License to do said work and all such work shall be done in full
compliance with County and Municipal requirements. All such movements shall be
made during hours which will least interfere with the normal operations of the
Building, and

shall be condemned or taken in any manner for any public or quasi-public use,

terminate as of the date of vesting of title. In the event that only a part of
the Demised Premises shall be so condemned or taken, then effective as of the
date of vesting of title, the Rent hereunder for such part shall be equitably
abated and this Lease shall continue as to such part not so taken. In the event

hereby granted as of the date of such vesting of title by notifying tenant in
writing of such termination within 60 days following the date on which Landlord
shall have received notice of vesting of title, or (b) if Landlord does not
elect to terminate this Lease, as aforesaid, this Lease shall be and remain
unaffected by such condemnation or taking, except that the Rent shall be abated
to the extent, if any, hereinbefore provided. In the event that only a part of
the Demised Premises shall be so condemned or taken and this Lease and the term
and estate hereby granted are not terminated as hereinbefore provided, Landlord
will, at its expense, restore with reasonable diligence the remaining
structural portions of the Demised Premises as nearly as practicable to the
same condition as it was in prior to such condemnation or taking.

         Section 12.02 In the event of termination in any of the cases in this
Article provided, this Lease and the term and estate hereby granted shall
expire as of the date of such termination with the same effect as if that were
the date hereinbefore set for the expiration of the term of this Lease, and the
Rent hereunder shall be apportioned as of such date.

         Section 12.03 In the event of any condemnation or taking of all or
part of the Building, Landlord shall be entitled to receive the entire award in
the condemnation proceeding, including any award made for the value of the
estate vested by this Lease in Tenant, and Tenant hereby expressly assigns to

arising in or to any such award or any part thereof, and Tenant shall be

eviction of Tenant, in whole or in part, and the Rent reserved shall in no wise
abate while said repairs or alterations are being made by reason of loss or
interruption of the business of Tenant because of the prosecution of any such
work, provided Landlord diligently proceeds therewith in such manner as to
cause the least possible interference with the Tenant's use and enjoyment of
the Demised Premises.

the Term of this Lease, Landlord may exhibit the Demised Premises to
prospective tenants.

doorways, corridors, stairs, toilets and other like public service portions of
the Building.

pursuant to any statute either of the United States or of any state, a petition
in bankruptcy or insolvency or reorganization or the appointment of a receiver
or trustee of all or a portion of Tenant's property or if Tenant shall
voluntarily file any such petition then, and in that event, the Lease shall be
deemed canceled and terminated, subject to the right of the trustee, with the
court's approval, to timely assume the unexpired Lease, provided, however, such
trustee faithfully complies with the provisions of subsections (b), (c) and (d)
of Section 365 of the Bankruptcy Reform Act of 1978. If Tenant shall make an
assignment for the benefit of creditors or enter into an arrangement, this
Lease shall be deemed canceled and terminated, in which event neither Tenant
nor any person claiming through or under Tenant shall be entitled to acquire or
remain in possession of the Demised Premises and Landlord shall have no further
liability hereunder to Tenant and any such person, if in possession, shall
forthwith quit and surrender the Demised Premises.

         Section 14.02 It is stipulated and agreed that in the event of the
termination of this Lease Pursuant to this Article, Landlord shall forthwith,
notwithstanding any other provisions of this Lease to the contrary, be entitled
to recover from Tenant as and for liquidated damages an amount equal to the
difference between the Rent and additional rent reserved hereunder for the
unexpired portion of the term demised and the then fair and reasonable rental
value of the Demised Premises for the same period. In the computation of such
damages, the difference between any installment of Rent becoming due hereunder
after the date of termination and the fair and reasonable value of the Demised
Premises for the period for which such installment was Payable shall be
discounted to the date of termination at the rate of four percent (4%) per
annum. If the Demised Premises, or any part thereof, be re-let by the Landlord
for the unexpired term of said Lease, or any part thereof, before presentation
of proof of such liquidated damages to any court, commission or tribunal, the
amount of rent reserved upon such refitting shall be prima facie evidence as to
the fair and reasonable rental value for the part or the whole of the premises

hereunder is not paid when due, or within three (3) business days after receipt

            (b) Any petition is filed by or against Tenant under any section or

            (c) Tenant shall become insolvent or transfer property in fraud of
creditors;

            (g) Tenant fails to observe, perform and keep each and every of the
covenants, agreements, provisions, stipulations and conditions herein contained
to be observed, performed and kept by Tenant (other than payment of Rent) and
fails to cure such default within ten (10) days after receipt of notice from
Landlord requiring that Tenant remedy, correct, desist, comply or cure any
breach (or if any such breach would reasonably require more than ten (10) days
to rectify, unless Tenant commences rectification within the ten (10) days
after receipt of notice and thereafter promptly, effectively and continuously
proceeds with the rectification of the breach and, in all such events, cures
such breach no later than thirty (30) days after such notice).

         Section 15.02 The occurrence of a Default, and failure by Tenant to
cure said Default within the period of time allowed for cure as set forth
above, if any, shall be an "Event of Default in which event Landlord shall have
the option to do and perform any one or more of the following in addition to,
and not in limitation of, any other remedy or right permitted it by law or by
this Lease:

            (a) Terminate this Lease by written notice to Tenant, in which
event Tenant shall immediately surrender the Demised Premises to Landlord, but
if Tenant shall fail to do so, Landlord may, without further notice and without
prejudice for any other remedy Landlord may have for possession or arrearage in
Rent enter upon the Demised Premises and expel or remove Tenant and Tenant's
effects, without being liable to prosecution or any claim for damages therefor;
and Tenant agrees to indemnify Landlord for all loss and damage which Landlord
may suffer by reason of such termination, whether through inability to relet
the Demised Premises, or through decrease in Rent, or otherwise; and/or

            (b) Declare the entire amount of Rent and other sums which would
become due and payable during the remainder of the Term, to be due and payable
immediately, in which event, Tenant agrees to pay the same at once, with
adjustment for the present value of same in accordance with Florida law,
together with all Rent therefore due, at Landlord's address as provided herein.
It is acknowledged that such payment shall not constitute a penalty or
forfeiture or liquidated damages, but shall merely constitute payment in
advance of the Rent for the remainder of the Term. Upon making such payment,
Tenant shall be entitled to receive from Landlord all rents received by
Landlord from other tenants on account of the Demised Promises during the Term,
less all costs, expenses and attorneys' fees of Landlord incurred in connection
with the recovery of possession and reletting of the Demised Premises, provided
that the monies to which Tenant shall so become entitled shall in no event
exceed the entire amount actually paid by Tenant to Landlord as an advance
payment of the Rent. The acceptance of such payment by Landlord shall not
constitute a waiver of any failure of Tenant thereafter occurring to comply
with any term, provision, condition or covenant of this Lease; and/or

            (c) Enter the Demised Premises as the agent of Tenant, without
being liable to prosecution of any claim for damages therefor, and relet the
Demised Premises as the agent of Tenant and for the account of Tenant, without
advertisement and by private negotiations and for any term Landlord deems
proper, and receive the rent therefor, and Tenant shall pay Landlord any
deficiency that may arise by reason of such reletting on demand, but Tenant
shall not be

                                    - 11 -
<PAGE>   15

entitled to any surplus so arising. Tenant shall reimburse Landlord for all
costs of reletting the Demised Premises including but not limited to
advertising expenses and commissions; and/or

            (d) As agent of Tenant, do whatever Tenant is obligated to do by
the provisions of this Lease and may enter the Demised Premises, without being
liable to prosecution or any claims for damages therefor, in order to
accomplish this purpose. Tenant agrees to reimburse Landlord immediately upon
demand for any sums advanced by Landlord and any expenses which Landlord may
incur in thus effecting compliance with this Lease on behalf of Tenant, which
sums shall bear interest at the highest legal rate from the date paid or
advanced by Landlord. Tenant further agrees that Landlord shall not be liable
for any damages resulting to Tenant from such action, whether caused by the
negligence of Landlord or otherwise.

         Section 15.03 Pursuit by Landlord of any of the foregoing remedies
shall not preclude the plus of general or special damages incurred, or of any
of the other remedies herein provided or any other remedies provided by law.

         Section 15.04 No act or thing done by Landlord or Landlord's agents
during the Lease Term shall be deemed a termination of the Lease or an
acceptance of a surrender of the Demised Premises, and no agreement to
terminate the Lease or accept a surrender of the Demised Premises shall be
valid, unless the same be made in writing and executed by Landlord. Neither the
mention in this Lease of any particular remedy, nor the exercise by Landlord of
any particular remedy hereunder, at law or in equity, shall preclude Landlord
from any other remedy Landlord might have under this Lease, at law or in
equity. Any waiver of or redress for any violation of any covenant or condition
contained in this Lease, shall not prevent a subsequent act, which would have
originally constituted a violation, from having all the force and effect of an
original violation. If Tenant shall be in Default, and as a result thereof,
Landlord shall bring any action under this Lease, or place this Lease or any
amount payable by Tenant hereunder with an attorney concerning or for the
enforcement of any of Landlord's rights hereunder, then Tenant in each and any
such case shall pay Landlord its reasonable attorney's fees and costs incurred.
The receipt by Landlord of rent with knowledge of the breach of any covenant in
this Lease shall not be deemed a waiver of such breach.

         Section 15.05 In the event such breach or threatened breach by Tenant
of any of the covenants or provisions of this Lease, Landlord shall have the
right of injunction and the right to invoke any remedy allowed at law or in
equity as if re-entry, summary proceedings and other remedies were not herein
provided for. Mention in this Lease of any particular remedy shall not preclude
Landlord from any other remedy, in law or in equity. The foregoing remedies and
rights of Landlord are cumulative.

                                  HOLDING OVER

         If Tenant remains in possession after expiration of the Lease Term
hereof, with Landlord's acquiescence and without any distinct agreement between
the parties, Tenant shall be a tenant at will and such tenancy shall be subject
to all the provisions hereof, except that the monthly rental shall be one
hundred fifty percent (150%) of the equivalent of the then-current monthly
installment of Rent due hereunder for the entire holdover period and there
shall be no renewal of this Lease by operation of law. Nothing in this
Paragraph shall be construed as a consent by Landlord to the possession of
Premises by Tenant after the expiration of the Lease Term.

                           ASSIGNMENT AND SUBLETTING

         Tenant shall not sublet any part of the Demised Premises, nor assign
this Lease or any interest herein, without prior written consent of Landlord,
which consent shall not be unreasonably withheld, provided that any such sublet
or assignment must be for a use which Landlord, in its reasonable discretion,
does not consider to be injurious to the Demised Premises; provided, further,
no such consent shall serve to release Tenant's liability hereunder. Consent by
Landlord to one assignment or sublease shall not destroy or waive this
provision, and all later assignments and subleases shall likewise be made only
upon prior written consent of Landlord. No assignment or sublease may be
requested in the event Tenant is in default hereunder. Tenant shall provide
Landlord with any and all information reasonably requested by Landlord with
respect to such sublessee or assignee, including, but not limited to financial
information and certified, audited financial statements. Sublessee or assignees
shall become liable directly to Landlord for all obligations of Tenant
hereunder without relieving Tenant's liability. In the event Tenant notifies
Landlord of Tenant's intent to sublease or assign this Lease, Landlord shall
within thirty (30) days from receipt of such notice (i) consent to such
proposed subletting, or (ii) refuse such consent. In the event Landlord gives
its consent to any such assignment or sublease, any rent, rental or other cost
to the assignee or subtenant for all or any portion of the Premises over and
above the Rent payable by Tenant for such space shall be paid to Landlord as
additional rent. In the event this Lease is either terminated or a sublease or
assignment is made as herein provided, Tenant shall reimburse Landlord for all
of the necessary administrative, legal and accounting services required in
order to accomplish such termination, assignment or subletting in an amount not
more than Five Hundred Dollars ($500.00).

         The sale or transfer of Tenant's voting stock (if a corporation) or
partnership interest (if a partnership) resulting in the transfer of control of
a majority of such stock or interest or the occupancy of the Premises by any
successor firm of the Tenant or by any firm into which or with which the Tenant
may become merged or consolidated shall be deemed an assignment of this Lease
requiring the prior written consent of Landlord in accordance with the
foregoing, provided,

                                    - 13 -

such consent shall not be required if the purchaser shall agree to become an
additional guarantor of this Lease.

                LANDLORD'S RIGHT TO PERFORM TENANT'S OBLIGATIONS

         If Tenant shall default in the observance or performance of any term
or covenant on its part to be observed or performed under or by virtue of any
of the terms or provisions in any Article of this Lease, Landlord, without
being under any obligation to do so and without thereby waiving such default,
may remedy such default for the account, and at the expense, of Tenant. If
Landlord makes any expenditures or incurs any obligations for the payment of
money in connection therewith, including, but not limited to, attorneys' fees
in instituting, prosecuting or defending any action or proceeding, such sums
paid or obligations incurred, with interest at the then maximum lawful rate,
and costs, shall be deemed to be additional rent hereunder and shall be paid to
it by Tenant on demand.

rent and observing and performing all the terms, covenants and provisions of
this Lease on Tenant's part to be observed and performed, Tenant may Peaceably
and quietly enjoy the Demised Premises, subject, nevertheless, to the terms and
conditions of this Lease.

for building or other purposes upon land adjacent to the Building, Tenant
shall, if necessary, afford to the person or persons causing or authorized to
cause such excavation or construction or other purpose license to enter upon
the Demised Premises for the purpose of doing such work as shall reasonably be
necessary to protect or preserve the Building, or any parts thereof, from
injury or damage and to support them by proper foundations, pinning and/or
underpinning, or otherwise.

State, County or Municipal authority, or for any other cause beyond the
reasonable control of Landlord. Landlord shall use due diligence to complete
all required repairs or other necessary work as quickly as possible so that
Tenant's inconvenience resulting therefrom may be for as short a period of time
as circumstances will permit. No diminution or abatement of rent or other
compensation shall or will be claimed by Tenant as a result therefrom, nor
shall this Lease, or any of the obligations of Tenant, be affected or reduced
by reason of such interruption, curtailment or suspension.

of removal from the Demised Premises and the Building of any refuse and rubbish
of Tenant and Tenant shall pay all bills therefore when rendered.

Landlord's interest in the Demised Premises, or to the holder of the such
mortgage or to the purchaser of the mortgaged premises in foreclosure, whereby

which would give the Tenant the right to terminate this Lease or to claim a
partial or total eviction pursuant to the terms of this Lease, if any, the
Tenant will not exercise such right until:

upon the .strict performance of, any covenant or condition of the Lease, or any
of the Rules and Regulations promulgated by Landlord, shall not prevent a

waiver of such breach. No provisions of this Lease shall be deemed to have been
waived by Landlord, unless such waiver be in writing signed by Landlord. No
payment by Tenant, or receipt by Landlord, of a lesser amount than the monthly
Rent herein stipulated shall be deemed to be other than on account of the
earliest stipulated Rent, nor shall any endorsement or statement on any check
or any letter accompanying any check or payment of rent be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice

keep harmless Landlord from all losses, damages, liabilities, injuries and
expenses, which may arise or be claimed against Landlord and be in favor of any
persons, firms or corporations, for any injuries or damages to the person or
property of any persons, firms or corporations, consequent upon or arising from
the use or occupancy of the Demised Premises by Tenant, or consequent upon or
arising from any acts, omissions, neglect or fault of Tenant, its agents,
servants, employees, licensees, visitors, customers, patrons or invitees, or
consequent upon or arising from Tenant's failure to comply with any laws,
statutes, ordinances, codes or regulations as herein provided; that Landlord
shall not be liable to Tenant for any damages, losses or injuries to the
persons or property of Tenant which may be caused by the acts, neglect,
omissions or faults of any persons, firms or corporations, except when such
injury, loss or damage results from negligence of Landlord, his agents or
employees. All personal property placed or moved into the Demised Premises or
Building shall be at the risk of Tenant or the owner thereof, and Landlord
shall not be liable to Tenant for any damage to said personal property. Tenant
shall maintain at all times during the term of this Lease an insurance policy

indemnify Landlord or pay Landlord's damages, if any, resulting from any
matters set forth hereinbefore in this Article 34.

         In case Landlord shall be made a party to any litigation commenced
against Tenant, then Tenant shall save and hold Landlord harmless in connection
with such litigation and shall pay all costs, expenses and attorney's fees
incurred or paid by Landlord in connection therewith.

                                   ARTICLE 35

common areas, and other facilities furnished by Landlord, including all parking
areas, truck way or ways, loading areas, pedestrian walkways and ramps,
landscaped areas, stairways, corridors and other areas and improvements
provided by Landlord for the general use, in common, of tenants, their offices,
agents, employees, servants, invitees, licensees, visitors, patrons and
customers, shall be at all times subject to the exclusive control and
management of Landlord, and Landlord shall have the right from time to time to
establish, modify and enforce reasonable rules and regulations with respect to
all facilities and areas and improvements; to police same; from time to time to

facilities hereinabove referred to; to restrict parking by and enforce parking
charges (by operation of meters or otherwise) to tenants, their officers,
agents, invitees, employees, servants, licensees, visitors, patrons and
customers; to close all or any portion of said areas or facilities to such
extent as may, in the opinion of Landlord's counsel, be legally sufficient to
prevent a dedication thereof or the accrual of any rights to any person or the
public therein; to close temporarily all or any portion of the public areas,
common areas or facilities; to discourage non-tenant parking; to charge a fee
for visitor and/or customer parking; and to do and perform such other acts in
and to said areas and improvements as, in the sole judgment of Landlord, the
Landlord shall determine to be advisable with a view to the improvement of the
convenience and use thereof by tests, their officers, agents, employees,
servants, invitees, visitors, patrons, licensees and customers. Landlord will
operate and maintain the common areas and other facilities referred to in such
reasonable manner as Landlord shall determine from time to time. Without
limiting the scope of such discretion, Landlord shall have the full right and
authority to designate a manager of the parking facilities and/or common areas
and other facilities who shall have full authority to make and enforce rules
and regulations regarding the use of the same or to employ all personnel and to
make and enforce all rules and regulations pertaining to and necessary, for the
proper operation and maintenance of the parking areas and/or common areas and
other facilities.

                             ENVIRONMENTAL MATTERS

         Without Landlord's prior written consent, Tenant shall not receive,

tenant in its normal business operations or Landlord in its management of the
Building. Tenant shall not commit or suffer to be committed, any waste on the
Demised Premises, nor shall Tenant permit the Demised Premises to be used in
any way that would. in the opinion of Landlord, be extra hazardous on account
of fire or otherwise that would in any way increase the premiums for or render
void the fire insurance on the Demised Premises or contents of the Building.

         "Hazardous Substances," as used in this Lease shall mean pollutants,
contaminants, toxic or hazardous wastes, or any other substances, the removal
of which is required or the use of which is restricted, prohibited or penalized
by any "Environmental Law," which term shall mean any federal, state or local
law or ordinance relating to pollution or protection of the environment.

         Tenant agrees to indemnify and hold Landlord harmless from all claims,
demands, actions, liabilities, costs, expenses, damages and obligations or any
nature including, without limitation, court costs and attorney's fees arising
from or as a result of the use of the Demised Premised by Tenant, its agents,
employees, contractors, invitees or licensees. The foregoing indemnification

                                SECURITY DEPOSIT

         Section 37.01 Upon execution of this Lease, Tenant shall pay the sum
of $8,900.00 to the Landlord (the "Security Deposit"), which Security Deposit
shall be held by Landlord in a interest bearing account and as security for the
performance by Tenant of Tenant's covenants and obligations under this Lease,
it being expressly understood that the Security Deposit shall not be considered
an advance payment of rental or a measure of Landlord's damages in case of
default by Tenant.

         Section 37.02 Landlord may, from time to time without prejudice to any
other remedy, use the Security Deposit to the extent necessary to make good any
arrearages of Rent or to satisfy any other covenant or obligation of Tenant
hereunder. Following any such application of the Security Deposit, Tenant shall
pay Landlord on demand the amount so applied in order to restore the Security
Deposit to its original amount.

         Section 37.03 If Landlord transfers its interest in the Demised
Premises during the Term of this Lease, Landlord may assign the Security
Deposit to the transferee and thereafter Landlord shall have no further
liability for the return of such Security Deposit.

                                 ATTORNEY FEES

         In the event of any dispute hereunder or of any action to interpret or
enforce this Lease, any provision hereof or any matter arising herefrom,
including the collection of Rent, the prevailing party shall be entitled to
recover its reasonable costs, fees and expenses, including, but not limited to,
witness fees, expert fees, consultant fees, attorney (in-house and outside
counsel), paralegal and legal assistant fees, costs and expenses, and other
professional fees, costs and expenses, in any action or declaratory action, in
any bankruptcy action, at pre-trial, at trial or on appeal.

                                TIME OF ESSENCE

         Time is of the essence of this Lease.

                                 LATE PAYMENTS

         Section 40.01 Payments of Rent received after the fifth day of the
month may be assessed an additional five percent (5%) charge as a late payment
penalty and shall be assessed an additional two percent (2%) charge for each
mouth thereafter until paid in full. Acceptance by Landlord of a payment in an
amount less than that which is currently due shall in no way affect Landlord's
rights under this Lease and in no way be an accord and satisfaction.

         Section 40.02 This provision does not prevent Landlord from declaring
the non-payment of Rent when due a Default hereunder.

                                   ARTICLE 41

                        SEVERABILITY AND INTERPRETATION

         Section 41.01 If any clause or provision of the Lease shall be deemed
illegal, invalid or unenforceable under present or future laws effective during
the Term, then and in that event, the

                                    - 23 -
<PAGE>   27

remainder of this Lease shall not be affected by such illegality, invalidity or
unenforceability, and, in lieu of each clause or provision of this Lease that
is illegal, invalid or unenforceable, there shall be added as a part of this
Lease a clause or provision as similar in terms to such illegal, invalid or
unenforceable clause or provision as may be possible and be legal, valid and
enforceable. If such invalidity is, in the sole determination of Landlord,
essential to the rights of both parties, Landlord shall have the right to
terminate this Lease on thirty (30) days' written notice to Tenant.

         Section 41.02 Should any of the provisions of this Lease require
judicial interpretation, it is agreed that the court interpreting or construing
the same shall not apply a presumption that the terms of any such provision
shall be more strictly construed against one party by reason of the rule of
construction that a document is to be construed most strictly against the party
who itself or through its agent prepared the same, it being agreed that the
agents of all parties have participated in the preparation of the stipulations
of this Lease.

                                   ARTICLE 42

                                  FLORIDA LAW

         This Lease has been made under and shall be construed and interpreted
under and in accordance with the laws of the State of Florida.

                                   ARTICLE 43

                                ENTIRE AGREEMENT

         Section 43.01 This Lease contains the entire agreement between
Landlord and Tenant and any agreement hereafter made between Landlord and
Tenant shall be ineffective to change, modify, waive, release, discharge,
terminate or effect an abandonment of this Lease, in whole or in part, unless
such agreement is in writing and signed by the party against whom enforcement
of the change, modification, waiver, release, discharge, termination or the
effecting of the abandonment is sought.

         Section 43.02 If any term or provision of this Lease shall, to any
extent be invalid or unenforceable, the remainder of this Lease shall not be
affected thereby and the balance of the term and provisions of this Lease shall
be valid and enforceable to the fullest extent either hereunder or as permitted
by law.

         Section 43.03 This Lease shall be construed in accordance with the
laws of the State of Florida.
