                       CORPOREX PROPERTIES OF TAMPA, INC.
                                 TAMPA, FLORIDA


        This is a Lease Agreement dated this 18th day of April, 1994 by and
between CORPOREX PROPERTIES OF TAMPA, INC., a Florida corporation, hereinafter
called the "Lessor", and BBJ ENVIRONMENTAL SOLUTIONS, INC., a Florida
corporation, hereinafter called "Lessee."

        WITNESSETH, that for and in consideration of the rent hereafter
reserved, and the covenants herein contained, the Lessor does hereby lease and
demise to the Lessee and said Lessee does hereby take and rent of Lessor, the
premises descried on Schedule 1 hereto, hereinafter referred to as the
"Premises", for the term as described on Schedule 1 hereto, or until such term
shall so cease and expire as hereinafter provided. The premises is located on a
parcel of land described on Schedule 1 hereto, hereinafter referred to as the
"developed parcel".

        The Lessee agrees to pay the Lessor, as rent for each year of said term,
the amounts set forth on Schedule 1 hereto, payable without deduction or demand,
in equal monthly installments (hereinafter sometimes referred to as the "basic
rental"), in advance, on the first day of each calendar month during the term
hereof, the first installment payable on the execution of this Lease and the
remaining installments payable in advance on the first day of each and every
month during the said term at Corporex Properties of Florida, P.O. 550152,
Tampa, FL 33655 or to such other party and at such other address as said Lessor
may from time to time designate to Lessee in writing. In the event Lessee fails
to pay the basic rental hereinbefore reserved within ten (10) days of the due
date, Lessee shall promptly pay to Lessor a service charge of five percent (5%).

        At the beginning of and for each lease year, as hereinafter defined,
after the first rental of this Lease until this Lease is terminated as
hereinafter set forth, the monthly basic rental shall be adjusted and changed as
follows:

        If the term of this Lease shall commence on a day other than the first
day of a calendar month, rent shall be paid in advance at the rate above
specified for the remaining portion of the month in which the term commenced. If
Lessor shall be unable to give possession of the premises on the date of the
commencement of the term hereof by reason of the fact that the premises are
located in a building being constructed and which has not been sufficiently
completed to make the premises ready for occupancy, or if the Lessor is unable
to give possession of the premises ready for occupancy, or if the Lessor is
unable to give possession of the premises on the date of commencement of the
term hereof by reason of the holding over or retention of possession of any
tenant, or if repairs, improvements, or decoration of the premises, or of the
building of which the premises form a part, are not completed, or for any other
reason, Lessor shall not be subject to any liability for the failure to give
possession on said date. Under
<PAGE>   4
such circumstances the rent reserved and covenanted to be paid herein shall not
be subject to any liability for the failure to give possession on said date.
Under such circumstances the rent reserved and covenanted to be paid herein
shall not commence until the possession of premises is tendered by Lessor with
Lessor's certification to Lessee that same are ready for occupancy. Should
tender of possession of premises by later or earlier than the beginning date
named above, then in that event, the beginning and ending dates of this Lease
shall be adjusted, by letter from Lessor to Lessee, to conform to date of such
tender of possession just as if the same had been originally named as the
beginning date, and this Lease shall run for its full term from the date of such
tender of possession. No such failure to give possession on the date of
commencement of the term shall in any other respect affect the validity of this
Lease or the obligations of Lessee hereunder. If permission is given to Lessee
to enter into the possession of the premises or to occupy premises other than
the premises prior to the date specified as the commencement of the term of this
Lease, Lessee covenants and agrees that such occupancy shall be deemed to be
under all the terms, covenants, conditions, and provisions of this Lease. Lessee
shall at any time during the term of this Lease, upon ten (10) days prior notice
by Lessor, execute and deliver to Lessor or to Lessor's mortgagee a Certificate
of Estoppel.

        Lessee has deposited with Lessor as security for Lessee's performance of
all of Lessee's obligations hereunder the security deposit specified in Schedule
I hereto, which Lessor shall hold without interest due Lessee If at any dine
during the term of this Lease, Lessee shall default in the payment of rent,
lessor may apply said security deposit to cure the default, the right to so
apply being hereby expressly granted to Lessor. In such event, Lessee shall
restore said deposit to the original amount with ten (10) days after demand
therefore by Lessor or its Agent In the event said deposit is not used or used
up as provided for above, then said deposit shall be returned to Lessee after
termination of this Lease and an inspection of the building by Lessor or its
Agent establishing that the building is being surrendered to the Lessor in
substantially the same condition in which it was received by the Lessee,
ordinary wear and tear excepted.

                           any, to the extent that such shall be due to the
                           nature of Lessee's use of the premises; provided,

                           the extent such repairs were made necessary by the
                           act or neglect of the Lessee or of the agents,
                           employees, licensees, invitees, or anyone claiming

                  alteration, modification, addition, or installation the Lessee
                  may wish to make, shall be made unless the Lessor shall first
                  have given written approval of the plans and specifications

                  modifications, additions, or installations, when made, shall
                  become, unless the Lessor elects otherwise as provided in
                  paragraph (13) hereof, the property of the Lessor and shall
                  remain upon and be surrendered with said premises as a part
                  thereof at the end of the term of this Lease. The Lessee
                  hereby agrees to indemnity, defend, and save harmless the
                  Lessor from any liability which may devolve upon the Lessor as
                  a consequence of such alterations, modifications, additions or
                  installations.

         (8)      To make, at Lessee's expense, all repairs and to do all acts
                  of maintenance becoming necessary in or upon the premises
                  during the term of this Lease, including specifically but not
                  being limited to the doors and door jams, both inside and
                  outside, loading docks, windows and window casings and sills,
                  both inside and outside, gutters and downspouts, and plate or
                  other glass windows and doors, and to make, at Lessee's
                  expense, all repairs and to do all acts of maintenance
                  becoming necessary during the term of this Lease to maintain,
                  and to replace all worn out and broken parts of, the heating,
                  plumbing, electrical, air-conditioning and sprinkler Systems
                  and equipment, and elevators, if any, and to enter into
                  service contracts, on behalf of Lessee only, for the
                  maintenance of the heating, air-conditioning and sprinkler
                  Systems, and elevators, if any. No such service contract shall
                  extend beyond the term of this Lease.

         (9)      To make no claim against the Lessor and to assume the
                  responsibility of defending, at Lessee's expense, any claim
                  which shall be made against the Lessor by the Lessee or any
                  agent, employee, or servant of the Lessee or by others
                  claiming the right to be on or about the premises or the
                  developed parcel through or under the Lessee for any injury,
                  loss, or damage to person or property occurring upon the
                  premises or the developed parcel from any cause. The Lessee
                  covenants and agrees to indemnity and save harmless the Lessor
                  from and against any and all liability, damages, expenses,
                  causes of the action, suits, claims, or judgements of any
                  person or persons, firm or corporation arising out of or in
                  any manner connected with injury or death to person, and
                  damage to or loss of personal property, in or on the demised
                  premises or the developed parcel, by reason of acts, failure
                  to act or negligence of Lessee or Lessee's agents, servants,
                  and employees or others in or about said premises. In
                  confirmation thereof, the Lessee covenants and agrees that it
                  will, at all times during the term hereof, at its own expense
                  carry and keep in full force and effect in companies
                  satisfactory to Lessor, public liability insurance in form
                  satisfactory to Lessor, with limits of:

                  (a)      at least FIVE HUNDRED THOUSAND DOLLARS ($500,000.00)
                           for injury, including death, to any one person, and

<PAGE>   9
                  (b)      at least ONE MILLION DOLLARS ($1,000,000.00) for
                           injury, including death in any one casualty, and

                  (c)      with property damage coverage of at least TWO HUNDRED
                           FIFTY THOUSAND DOLLARS ($250,000.00) or in such
                           greater amounts of insurance coverage as Lessor may
                           from time to time reasonably require. Lessee shall
                           also, at its own cost, carry plate glass insurance on
                           said premises. All such policies shall name the
                           Lessor and the Lessee as parties insured, and shall
                           contain a provision that the same may not be canceled
                           without giving to the Lessor at least ten (10) days
                           prior written notice. Each such policy, or a
                           certificate showing the same to be in effect, shall
                           be delivered to the Lessor at the commencement of the
                           Term hereof, and renewals thereof shall be delivered
                           to the Lessor at least ten (10) days prior to
                           expiration or cancellation of any such policy. The
                           Lessee covenants and agrees that no liability shall
                           be imposed upon the Lessor because of any injury or
                           damage to person or property, or because of any
                           interference with the services and facilities to be
                           performed or provided by Lessor as hereinabove
                           described, caused by accidents, repairs, riots,
                           strikes, or any reason beyond the control of the
                           Lessor.

         (10)     This Lease, and all rights of Lessee hereunder, are
                  subject and subordinate to any first mortgage which does now
                  or may hereafter affect the premises, and to any and all
                  renewals, modifications, consolidations, replacements, and
                  extensions thereof. It is the intention of the parties that
                  this provision be self-operative and that no further
                  instrument shall be required to effect such subordination of
                  this Lease. Lessee shall, upon demand at any time or times,
                  execute, acknowledge, and deliver to Lessor any and all
                  instruments that may be necessary or proper to subordinate
                  this Lease, and all rights of Lessee hereunder, to any such
                  mortgage or deed of trust or to confirm or evidence said
                  subordination; and Lessee hereby appoints the Lessor as its
                  attorney-in-fact to execute such instruments in Lessee's
                  behalf. Provided, however, that as long as Lessee continues
                  payment of rent and performance of its covenants hereunder,
                  Lessee's right of possession of the demised premises under
                  this Lease shall not be affected by any foreclosure of such
                  deed of trust or mortgage. Notwithstanding the subordination
                  of this Lease as aforesaid, any present or future mortgagee or
                  beneficiary under any mortgage or deed of trust may, by giving
                  Lessee written notice thereof, require that this Lease shall
                  be senior in lien to such mortgage or deed of trust, and that
                  Lessee attorn to the purchaser upon such foreclosure sale and
                  to recognize such purchaser as the Lessor under this Lease
                  Lessee agrees to execute and deliver, at any time and from
                  time to time, upon the request of Lessor, or of any such
                  holder, any instrument which, in the reasonable judgment of
                  the Lessor, may be necessary or appropriate in any such
                  foreclosure proceeding or otherwise to evidence such
                  attornment. Lessee further waives the provisions of any
                  statute or rule of law, now or hereafter in effect, which may
                  give or purport to give Lessee any right or election to
                  terminate or otherwise adversely affect this Lease, and the
                  obligations of Lessee hereunder, the event of any such
                  foreclosure.

         (11)     This Lease, and all rights of Lessee hereunder, are subject
                  and subordinate to all of the matters of title of record as of
                  the date hereof.
<PAGE>   10
         (12)     To comply with all rules and regulations set forth on Schedule
                  4 hereto, and any reasonable rule and regulations hereafter
                  established by the Lessor, for the use of the premises and the
                  developed parcel.

         (13)     To remove from the premises, at the expiration or other
                  termination of this Lease, all goods and effects not belonging
                  to the Lessor, and to surrender possession of the premises and
                  all fixtures and furnishings connected therewith in good
                  repair, order and condition in all respects, reasonable wear
                  and ordinary use thereof excepted; and if the Lessee shall
                  have made any alterations, additions, installations, or
                  modifications in or to the premises, whether consented to by
                  the Lessor or not, Lessee shall, if requested to do so by the
                  Lessor in writing prior to the expiration of the term of this
                  Lease, remove the same or such thereof as may be specified in
                  such notice, and repair any damage caused by such removal, all
                  at Lessee's expense. If Lessee fails to perform any of the
                  foregoing obligations, Lessor is authorized to do so in
                  Lessee's behalf and to sell such articles and effects left on
                  the premises as may be saleable. The proceeds of such sale
                  shall be applied toward the expenses thus incurred, and Lessee
                  agrees to pay any balance promptly.

         (14)     Not to operate any machinery in the premises which may cause
                  excessive vibration, noise or damage to the premises; nor to
                  use a loudspeaker which can be heard outside the premises.

         (15)     Not to place any exterior advertising signs or awnings upon
                  the premises or the developed parcel, not to place any
                  advertising signs or posters on the interior of the show
                  windows, and not to change the color of the exterior painting,
                  without the prior written approval of the Lessor.
                  Notwithstanding any previous sign approvals by Lessor, if at
                  any time the Lessor adopts a new sign specification for the
                  warehouse building, Lessee agrees at Lessee's expense to
                  promptly replace or alter its existing sign to comply with the
                  Lessor's new sign specification.

         (16)     Not to execute any assignment, sublease, concession or
                  mortgage of this Lease, or of the premises, or of any part
                  thereof, without first having obtained the written consent of
                  the Lessor.

         (17)     To permit the Lessor to enter the premises at any reasonable
                  time for the purpose of making repairs, or to determine the
                  condition of the premises and the Lessee's compliance with the
                  conditions of this Lease after notice to the Lessee.

         (18)     To permit the Lessor to show the premises to prospective
                  purchasers at all reasonable times and to prospective tenants
                  at all reasonable times within one hundred eighty (180) days
                  prior to the expiration of the term of this Lease, and to
                  exhibit notices for lease or sale within one hundred eighty
                  (180) days prior to the expiration of the term after notice to
                  the Lessee.

         (19)     To notify Lessor promptly of any defect appearing in the
                  premises or common areas of the developed parcel which the
                  Lessor is obligated to maintain and repair under Paragraph (3)
<PAGE>   11
                  or (4) of agreements and covenants of Lessor.

         (20)     Lessee's covenants to pay rental, taxes, insurance, and other
                  sums due hereunder are independent of Lessor's covenants
                  hereunder, and Lessee shall have no right to withhold any such
                  payments on account of any alleged failure by Lessor to
                  perform or comply with any of Lessor's covenants.

         (21)     Anything contained in the foregoing provisions of this section
                  to the contrary notwithstanding, neither Lessee nor any other
                  person having an interest in the possession, use, occupancy,
                  or utilization of the premises shall enter into any lease,
                  sublease, license, concession or other agreement for use,
                  occupancy or utilization of space in the premises which
                  provides for rental or other payment for such use, occupancy,
                  or utilization based, in whole or in part, on the net income
                  or profits derived by any person from the premises lease,
                  used, occupied or utilized (other than an amount based on a
                  fixed percentage or percentages of receipts or sales), and any
                  such purported lease, sublease, license, concession or other
                  agreement shall be absolutely void and ineffective as a
                  conveyance of any right or interest in the possession, use,
                  occupancy or utilization of any part of the premises.

C.       GENERAL PROVISIONS:

         (1)      Eminent Domain: Lessee agrees that if the premises, or any
                  part thereof, shall be taken or condemned for public or
                  quasi-public use or purpose by any competent authority, Lessee
                  shall have no claim against Lessor and shall not have any
                  claim or right to any portion of the amount that may be
                  awarded as damages or paid as a result of any such
                  condemnation, it being agreed that the full amount of such
                  award, if any, made by the taking authorities shall be paid to
                  and retained by Lessor, free of any claim by Lessee to any
                  portion thereof, and all rights of Lessee to damages therefor,
                  if any, are hereby assigned by Lessee to Lessor. In the event
                  that all or substantially all of the premises shall be taken
                  or condemned by any governmental authority, then the term of
                  this Lease shall cease and terminate from the date on which
                  the Lessee is required, by such taking authority, to surrender
                  possession of said premises and the Lessee shall not have nor
                  make any claim against Lessor for the value of any unexpired
                  term of this Lease. In the event that a portion of the
                  premises shall be taken or condemned by any governmental
                  authority, then this Lease shall continue in full force and
                  effect, and rent shall abate in an amount which bears the same
                  ratio to the monthly basic rental as the value of the floor
                  space taken bears to the value of the total floor space of the
                  premises. All rentals and other sums payable by Lessee
                  hereunder shall be adjusted to the date on which Lessee is
                  required, by the taking authority, to surrender possession of
                  the premises or portion of the premises so taken.

         (2)      Lessee Holding Over: if the Lessee shall not immediately
                  surrender possession of the premises at the termination of
                  this Lease, the Lessee shall become a Lessee from month to
                  month, provided rent shall be paid to and accepted by the
                  Lessor, in advance, at double the rate of rental payable
                  hereunder just prior to the termination of this Lease, but
                  unless and until the Lessor shall accept such rental from the
                  Lessee, the Lessor shall continue to be entitled to retake
                  possession of the premises without any prior notice whatsoever
                  to Lessee. If the Lessee shall fail to surrender possession of
                  the premises immediately upon the expiration of
<PAGE>   12
                  the term hereof, the Lessee hereby agrees that all of the
                  obligations of the Lessee and all rights of the Lessor
                  applicable during the term of this Lease shall be equally
                  applicable during such period of subsequent occupancy, whether
                  or not a month to month tenancy shall have been created as
                  aforesaid, and that if a month to month tenancy shall have
                  been created as aforesaid, said month to month tenancy may be
                  terminated only upon thirty (30) days advance written notice
                  by the party so terminating to the other party.

         (3)      Fire Clause. This Lease is made on condition that, if the
                  premises, or any part thereof, be destroyed or damaged by fire
                  or other casualty covered by a Standard Fire and Extended
                  Coverage Policy, so as to render said premises unfit for use
                  and occupancy, a proportionate part of the rent shall be
                  suspended and abated until said premises shall have been put
                  in as good condition for use and occupancy as at the time of
                  such damage or destruction, or until this Lease shall be
                  canceled and terminated as next hereinafter provided, as the
                  case may be. It shall be the duty of the Lessor to determine
                  and to notify the Lessee, in writing, within forty five (45)
                  days after such damage or destruction, the date by which the
                  premises can be fully restored with reasonable diligence. II
                  the date by which such restoration can be completed, as stated
                  in the Lessor's notice, shall be later, than six (6) months
                  after such damage or destruction, then either party hereto
                  shall have the right, to be exercised within thirty (30) days
                  after receipt of such notice from the Lessor, to cancel and
                  terminate this Lease, by giving to the other party a written
                  notice of his desire so to cancel and terminate; but if this
                  Lease shall not be so canceled, it shall remain in full force
                  and effect and the Lessee shall reoccupy the premises when
                  fully restore([ However, if the date by which such restoration
                  can be completed, as stated in the Lessor's notice, shall be
                  earlier than six (6) months after such damage or destruction,
                  this Lease shall remain in full force and effect, and the
                  Lessee shall reoccupy the premises when fully restored,
                  provided, however, that if, at the expiration of a period of
                  six (6) months following such damage or destruction, the
                  premises shall not have been fully restored as a result of
                  some cause beyond the Lessor's control, the Lessor shall have
                  the right to complete such restoration, provided he shall use
                  reasonable diligence in so doing, without thereby affording to
                  the Lessee the right to cancel this Lease. In case of damage
                  or destruction of the premises by an uninsured casualty, or if
                  the estimated cost of repair or restoration shall exceed
                  Lessor's insurance recovery, the Lessor, at its option, may
                  cancel and terminate this Lease by giving the Lessee a written
                  notice to this effect within forty five (45) days after such
                  damage or destruction, but if the Lessor shall not so elect to
                  terminate, all of the provisions hereinbefore contained
                  respecting an insured casualty shall be equally applicable to
                  such non-insured casualty.

         (4)      Termination Prior to Expiration of the Term: It is mutually
                  covenanted and agreed that if the Lessee shall fail to keep
                  and perform all of the covenants, conditions, and agreements
                  herein made binding upon the Lessee, or if the estate hereby
                  created shall be taken on execution or other process of law,
                  or if the Lessee shall be declared bankrupt or insolvent
                  according to law, or if a receiver or other similar officer
                  shall be appointed to take charge of all or any part of the
                  property of the Lessee, or if any assignment shall be made of
                  the Lessee's property for the benefit of creditors, then and
                  in each such case, Lessee shall be in default of this Lease,
                  and, at the sole option of the Lessor, the Lessee's right of
                  possession shall thereupon cease and terminate and the Lessor
                  shall be entitled to possession of the premises and to reenter
                  the same without further demand of rent or demand of
                  possession
<PAGE>   13
                  of said premises, and may forthwith recover possession of said
                  premises by whatever process of law may be available in the
                  jurisdiction in which the premises may be located, any notice
                  to quit or notice of intention to enter being hereby expressly
                  waived by the Lessee, or the Lessor may retake possession
                  without process of law. In the event of such reentry or
                  retaking, the Lessee shall, nevertheless remain liable and
                  answerable for the full rental to the date of such retaking or
                  reentry, and for damages for the deficiency or loss of rent
                  which the Lessor may thereby sustain in respect of the balance
                  of the term; and in such case, the Lessor shall have the right
                  to let the premises for the benefit of the Lessee, in
                  liquidation and discharge, in whole or in part, as the case
                  may be, of he liability of the Lessee hereunder; and such
                  damages, at the option of the Lessor, may be recovered at the
                  time of retaking or reentry, or in separate actions from time
                  to time as the Lessee's obligation to pay rent would have
                  accrued if the term had continued, or from time to time as
                  said damages shall have been made more easily ascertainable by
                  relettings, or such action, at the option of the Lessor, may
                  be deferred until the expiration of the term, in which latter
                  event, the cause of action shall not be deemed to have accrued
                  until the expiration of said term. The Lessor, however, may
                  refrain from terminating the Lessee's right of possession, and
                  in such case, may enforce against the Lessee the provisions of
                  this Lease for the full term hereof. In the event legal
                  proceedings are instituted against Lessee, by the Lessor,
                  either for payment of rent or for possession, then Lessee
                  agrees to pay all court costs instant to such proceedings,
                  together with reasonable attorneys' fees.

                  If any person other than the Lessee shall initiate the action
                  which shall entide the Lessor to terminate this Lease as
                  aforesaid, it is understood and agreed that the Lessor must
                  defer terminating this Lease until the expiration of a period
                  of fifteen (15) days after written notice from the Lessor to
                  the Lessee that such action shall have been taken.

                  No waiver by the Lessor of any breach of any covenant or
                  condition herein contained shall operate as a waiver of the
                  covenant or condition itself or of any subsequent breach
                  thereof; nor shall any waiver be implied should a compromise
                  between the parties be effected after the Lessor shall have
                  initiated any action in regard thereto.

(5)      Other General Provisions:

         (a)      In case two (2) or more persons shall constitute the Lessee
                  hereunder, the covenants, obligations, and agreements herein
                  made binding upon the Lessee, shall be the joint and several
                  obligations of such persons, and in the event of the death of
                  any one or more of them, the survivor: or survivor shall
                  succeed to all Lessee's rights, tide, and interest hereunder;
                  and this Lease shall be binding upon and shall inure to the
                  benefit of not only the parties hereto, but also their
                  respective heiss, personal representatives, successors, and
                  assigns.

         (b)      All notices required or permitted to be given hereunder shall
                  be by registered mail to the Lessor, at the address set forth
                  in Schedule I hereto, unless and until the Lessee should be
                  notified otherwise, in writing; and those directed to the
                  Lessee shall be addressed to the premises, unless and until
                  the Lessor should be notified otherwise, in writing.
<PAGE>   14
         (c)      This Lease, including any exhibits, schedules or attachments
                  hereto, constitutes the entire agreement of the parties in
                  respect of the premises. No representations, inducements or
                  agreements, oral or otherwise, between the parties not
                  contained in this Lease, or any exhibits, schedules or
                  attachments hereto, shall be of any force or effect

         (d)      The Lessee waives all right to trial by jury in any
                  proceeding, which may be instituted by the Lessor against the
                  Lessee in respect of the premises.

         (e)      If any provision of this Lease shall at any time be deemed to
                  be invalid or illegal by any court or competent jurisdiction,
                  this Lease shall not be invalidated thereby, and in such event
                  this Lease shall be read and construed as if such invalid or
                  illegal provision had not been contained herein.

         (f)      Anything contained in this Lease to the contrary
                  notwithstanding, Lessee agrees that Lessee shall look solely
                  to the estate and property of Lessor for the collection of any
                  judgment (or other judicial process) requiring the payment of
                  money by Lessor in the event of any default or breach by
                  Lessor with respect to any of the terms and provisions of this
                  Lease to be kept, observed, and performed by Lessor, subject,
                  however, to the prior rights of any ground or underlying
                  Lessors or any mortgagee of all or any part of the property;
                  no other assets of Lessor shall be subject to levy, execution
                  or other judicial process for the satisfaction of Lessee's
                  claim Nothing in this Lease shall be construed in any event
                  whatsoever to impose any personal liability upon the trustees,
                  officer or the shareholders of the Lessor, or of the general
                  or limited partners, comprising the Lessor, as Lessor herein
                  or otherwise.

         (g)      Lessor grants to Lessee during the term hereof the
                  nonexclusive use, in common with others, of all non-allocated
                  parking areas within the developed parcel for the
                  accommodation and parking of passenger automobiles of Lessee,
                  its officers, agents, employees, and visitors. Lessor reserves
                  the right, however, to designate, for the specific account of
                  Lessee, specific parking areas or spaces within the developed
                  parcel. All parking areas and other facilities which may be
                  furnished by Lessor within the developed parcel, including
                  employee parking areas, truck ways, loading docks, pedestrian
                  sidewalks and ramps, landscaped areas, and other areas and
                  improvements which may be provided by Lessor for the general
                  use, in common with other lessees, their officers, agents,
                  employees, and visitors, shall at all times be subject to the
                  exclusive control and management of Lessor and Lessor shall
                  have the right from time to time to establish, modify, and
                  enforce reasonable rules and regulations with respect to all
                  facilities referred to in this paragraph, to change truck
                  routes to such extent as the Lessor may desire, provided that
                  the premises are adequately served by the new route, to
                  restrict parking by Lessees, their officers, agents, and
                  employees to employee parking areas; to establish and from
                  time to time change the level of parking surfaces, to close
                  all or any portion of said areas or facilities to such extent
                  as may, in the opinion of Lessor's counsel, be legally
                  sufficient to prevent a dedication thereof or the accrual of
                  any rights to any person or
<PAGE>   15
                  to the public therein; to close temporarily all or any portion
                  of the parking areas or facilities to discourage nontenant
                  parking, and to do and perform such other acts in and to said
                  areas and improvements as, in the use of good business
                  judgement, the Lessor shall determine to be advisable with a
                  view to the improvement of the conveniences and use thereof by
                  Lessees, their officers, agents, employees, and visitors.
                  Lessee agrees that it will cause its officers, agents, and
                  employees to park their automobiles only in such areas as
                  Lessor may from time to time designate as employee parking
                  areas.

(h)      Lessor shall have the following rights exercisable without notice and
         without liability to Lessee:

                  (i)      To change the name or street address of the building.

                  (ii)     To have pass keys to the leased premises.

                  (iii)    To require all persons entering or leaving the

                           watchman by registration or otherwise and to
                           establish their right to enter or leave, and to
                           exclude or expel any peddler, solicitor or beggar at
                           any time from the premises or the Building.

                  (iv)     To approve the weight, size and location of safes,
                           computers, and other heavy articles or equipment in
                           and about the premises and to require all such items
                           and other office furniture and equipment to be moved
                           in and out of the premises only at such times and in
                           such manner as Lessor shall direct and in all events
                           at Tenant's sole risk and responsibility.

                  (v)      At any time or times, to decorate and to make, at its
                           own expense, repairs, alterations, additions and
                           improvements, structural or otherwise, in or to the
                           premises or any other part of or structure within the
                           developed parcel, and to perform any acts related to
                           the safety, protection and preservation thereof, and
                           during such operations to take into and through the
                           premises or any part of the developed parcel all
                           material and equipment required; to close or
                           temporarily suspend operation of entrances, doors,
                           corridors or other facilities, provided that Lessor
                           shall cause as little inconvenience or annoyance to
                           Lessee M is reasonably necessary in the
                           circumstances, and shall not do any act which
                           permanently reduces the size of the premises. Lessor
                           may do any such work during ordinary business hours
                           and Lessee shall pay Lessor for overtime and any
                           other expenses incurred if such work is done during
                           after hours at Lessee's request.

(i)               The submission of this Lease for examination does not
                  constitute reservation of or an option for the leased
                  premises, and this Lease becomes effective as a lease only
                  upon the execution by both Lessor and Lessee.
<PAGE>   16
         (j)      If any provision of this Lease Agreement conflicts with any
                  provision contained in Schedule 1 hereto, the provision as
                  contained in Schedule 1 shall prevail; however, the provisions
                  of this Lease shall be given effect to the fullest extent not
                  directly in conflict with a provision of said Schedule 1.

         (k)      This Lease may be executed in one or more counterparts, and,
                  if this Lease is so executed, all counterparts shall
                  constitute one and the same legal document

         (1)      This Lease may not be modified, changed or terminated in whole
                  or in part in any manner other than by an agreement in writing
                  duly executed by the party to be changed therewith.

         (m)      The Lessee shall accept performance of any of Lessor's
                  obligations hereunder by any person or entity holding a
                  mortgage of the premises or the developed parcel. However, no
                  mortgagee not in possession of the premises or the developed
                  parcel shall have any obligation or liability hereunder.

         (n)      Nothing contained in this Lease shall be deemed or construed
                  to create a partnership or joint venture of or between the
                  Lessee and the Lessor, or to create any relationship between
                  the parties other than that of Lessee or Lessor.

         (o)      This Lease shall be construed and enforced in accordance with
                  the Laws of the State of Florida.

         (p)      Financial Statements: Within twenty (20) days of written
                  request by Lessor, Lessee will provide Lessor with its most
                  recent financial statement, certified to be true and correct
                  by either Lessee's chief financial officer or an independent
                  certified public accountant; provided, however, Lessor may
                  only share such statements with its mortgagee, ground lessor,
                  prospective mortgagees and ground lessors, purchasers and
                  partners, and attorneys, accountants, and other advisors of
                  Lessor and each of the foregoing.

               IN WITNESS WHEREOF, Lessor and Lessee have hereunto executed this
Lease as of the day and year first above written.
