          "APPRAISAL PROCEDURE" shall mean the following procedure for
          determining the Fair Market Sale Value of any item of Equipment. If
          either Lessor or Lessee shall request by notice (the "Appraisal

          Procedure, (i) Lessor and Lessee shall, within 15 days after the

          satisfactory to them, or (ii) if the parties are unable to agree on a
          mutually acceptable appraiser within such time, Lessor and Lessee
          shall each appoint one independent appraiser (PROVIDED that if either
          party hereto fails to notify the other party hereto of the identity of
          the independent appraiser chosen by it within 30 days after the
          Appraisal Request, the determination of such value shall be made by
          the independent appraiser chosen by such other party), and (iii) if
          such appraisers cannot agree on such value within 20 days after their
          appointment and if one appraisal is not within 5% of the other
          appraisal, Lessor and Lessee shall choose a third independent
          appraiser mutually satisfactory to them (or, if they fail to agree
          upon a third appraiser within 25 days after the appointment of the
          first two appraisers, such third independent appraiser shall within 20
          days thereafter be appointed by the American Arbitration Association),

          within 20 days after his appointment, after consultation with the

          independent appraisers. If the first two appraisals are within 5% of
          each other, then the average of the two appraisals shall be the Fair

amounts owing hereunder. Interest shall be computed on the basis of a 360-day
year and actual days elapsed.

          (c)  This Lease is a net lease, and Lessee's obligation to pay all
rent and all other amounts payable hereunder is ABSOLUTE AND UNCONDITIONAL under
any and all circumstances and shall not be affected by any circumstances of any
character whatsoever, including, without limitation, (i) any set-off,

rules or orders; (3) the insolvency, bankruptcy or reorganization of any person;
and (4) any other cause whether similar or dissimilar to the foregoing, any
present or future law to the contrary notwithstanding. Lessee hereby waives, to
the extent permitted by applicable law, any and all rights which it may now have
or which may at any time hereafter be conferred upon it, by statute or
otherwise, to terminate, cancel, quit or surrender the lease of any Equipment.
If for any reason whatsoever this Lease or any Supplement, other than pursuant
to Section 16(b) hereof, shall be terminated in whole or in part by operation of
law or otherwise, Lessee will nonetheless pay to Lessor an amount equal to each
installment of rent at the time such installment would have become due and
payable in accordance with the terms hereof. Each payment of rent or other
amount paid by Lessee hereunder shall be final and Lessee will not seek to

Lessor at such place within the continental United States of America as Lessor
shall designate in

                                        -7-

          (d)  CONSENTS AND PERMITS.

          The execution, delivery and performance of this Lease does not
require any approval or consent of any trustee, shareholder, partner, sole
proprietor, or holders of any indebtedness or obligations of Lessee, and will

          There is no action, suit, investigation or proceeding by or before any
court, arbitrator, administrative agency or other governmental authority pending
or threatened against or affecting Lessee (A) which involves the transactions

          (g)  UNITED STATES SOURCE INCOME.

          No items of Equipment shall be used in a way that results in the
creation of an item of income to Lessor, the source of which for Federal Income
Tax purposes is without the United States.

     9.   LIENS.

          Lessee will not directly or indirectly create, incur, assume, suffer,

of such policy, and require that the interest of Lessor and any such Owner be
continued insured regardless of any breach of or violation by Lessee of any
warranties, declarations or conditions contained in such insurance policy. At
Lessor's or such Owner's option, Lessee shall furnish to Lessor and such Owner a
certificate or other evidence satisfactory to Lessor that such insurance
coverage is in effect provided, however, that Lessor and such Owner shall be
under no duty to ascertain the existence or adequacy of such insurance.

other taxes), imposts, duties, withholdings, assessments and other governmental
charges of whatever kind or character, however designated (together with any
penalties, fines or interest thereon), all of the foregoing being herein
collectively called "Impositions", which are at any time levied or imposed
against Lessor, Lessee, this Lease, the Equipment or any part thereof by any
Federal, State, or Local Government or taxing authority in the United States or
by any foreign government or any subdivision or taxing authority thereof upon,
with respect to, as a result of or measured by (i) the Equipment (or any part
thereof), or this Lease or the interest of the Lessor therein; or (ii) the
purchase, ownership, delivery, leasing, possession, maintenance, use, operation,
return, sale or other disposition of the Equipment or any part thereof; or (iii)
the rentals, receipts or earnings payable under this Lease or otherwise arising
from the Equipment or any part thereof; EXCLUDING, HOWEVER, taxes based on or
measured by the net income of Lessor that are imposed by (1) the United States
of America, or (2) the State of Florida or any political subdivision of the
State of Florida, or (3) any other State of the United States of America or any
political subdivision of any such State in which Lessor is subject to
Impositions as the result (whether solely or in part) of business or
transactions unrelated to this Lease. In case any report or return is required
to be filed with respect to any obligation of Lessee under this Section or
arising out of this Section, Lessee will notify Lessor of such requirement and
make such report or return in such manner as shall be satisfactory to Lessor;
PROVIDED, that the payment of any use taxes shall be made in such manner as
specified by Lessor in writing to Lessee; or (iv) The provisions of this Section
shall survive the expiration or earlier termiation of this Lease.

                              -10-


          (b)  SPECIAL TAX PROVISIONS.

               (i)  The Owner of the items of Equipment, shall be entitled to
take into account in computing its Federal income tax liability, Current Tax
Rate and such deductions, credits, and other benefits as are provided by the
Code to an owner of property.

               (ii) For the purposes of this Subsection 11(b) only, the term
"Owner" shall include the "common parent" and all other corporations included in
the affiliated group, within the meaning of Section 1504 of the Code (or any
other successor section thereto), of which Owner is or becomes a member.

     12.  COMPLIANCE WITH LAWS; OPERATION AND MAINTENANCE.

          (a)  Lessee will use the Equipment in a careful and proper manner,
will comply with and conform to all governmental laws, rules and regulations
relating thereto, and will cause the Equipment to be operated in accordance with
the manufacturer's or supplier's instructions or manuals.

          (b)  Lessee will, at its own expense, keep and maintain the Equipment
in good repair, condition and working order and furnish all parts, replacements,
mechanisms, devices and servicing required therefor so that the value, condition
and operating efficiency therefor will at all times be maintained and preserved,
reasonable wear and tear excepted. All such repairs, parts, mechanisms, devices
and replacements shall immediately, without further act, become the property of
Lessor and part of the Equipment.

          (c)  Lessee will not make or authorize any improvement, change,
addition or alteration to the Equipment (i) if such improvement, change,
addition or alteration will impair the originally intended function or use of
the Equipment or impair the value of the Equipment as it existed immediately
prior to such improvement, change, addition or alteration; or (ii) if any parts
installed in or attached to or otherwise becoming a part of the Equipment as a
result of any such improvement, change, addition or alteration shall not be
readily removable without damage to the Equipment. Any part which is added to
the Equipment without violating the provisions of the immediately preceding
sentence and which is not a replacement or substitution for any property which
was a part of the Equipment, shall remain the property of Lessee and may be
removed by Lessee at any time prior to the expiration or earlier termination of
the Lease Term. All such parts shall be and remain free and clear of any Liens.
Any such part which is not so removed prior to the expiration or earlier
termination of the Lease Term shall, without further act, become the property of
Lessor.

     13.  INSPECTION.

          Upon prior notice, Lessor or its authorized representatives may at any
reasonable time or times inspect the Equipment when it deems it necessary to
protect its interest therein.

                                        -11-


     14.  INDEMNIFICATION.

          Lessee shall, at its expense, attach to each item of Equipment a
notice satisfactory to Lessor disclosing Owner's ownership of such item of
Equipment.

     15.  PERSONAL PROPERTY.

          Lessee represents that the Equipment shall be and at all times remain
separately identifiable personal property. Lessee shall, at its expense, take
such action (including the obtaining and recording of waivers) as may be
necessary to prevent any third party from acquiring any right to or interest in
the Equipment by virtue of the Equipment being deemed to be real property or a
part of real property or a part of other personal property, and if at any time
any person shall claim any such right or interest, Lessee shall, at its expense,
cause such claim to be waived in writing or otherwise eliminated to Lessor's
satisfaction within 30 days after such claim shall have first become known to
Lessee.

     16.  LOSS OR DAMAGE.

          (a)  All risk of loss, theft, damage or destruction to the Equipment
or any part thereof, however incurred or occasioned, shall be borne by Lessee
and, unless such occurrence constitutes an Event of Loss pursuant to paragraph
(b) of this Section, Lessee shall promptly give Lessor written notice hereof
and shall promptly cause the affected part or parts of the Equipment to be
replaced or restored to the condition and repair required to be maintained by
Section 12 hereof.

          (b)  If an Event of Loss with respect to any item of Equipment shall
occur, Lessee shall promptly give Lessor written notice thereof, and Lessee
shall pay to Lessor as soon as it receives insurance proceeds with respect to
said Event of Loss but in any event no later than 180 days after the occurrence
of said Event of Loss an amount equal to the sum of (i) the  Stipulated Loss
Value of such item of Equipment computed as of the Rent Payment Date with
respect to such item of Equipment on or immediately preceding the date of the
occurrence of such Event of Loss; and (ii) all rent and other amounts due and
owing hereunder for such item of Equipment on or prior to the Loss Payment Date.
Upon payment of such amount to Lessor, the lease of such item of Equipment
hereunder shall terminate, and Lessor will transfer within forty days to Lessee,
Lessor's right, title and interest in and to such item of Equipment, on an
"as-is, where-is" basis, without recourse and without representation or
warranty, express or implied, other than a representation and warranty that
such item of Equipment is free and clear of any Lessor's Liens.

          (c)  Any payments received at any time by Lessor or Lessee from any
insurer with respect to loss or damage to the Equipment shall be applied as
follows: (i) if such payments are received with respect to an Event of Loss,
payments for all physical damage shall be paid to Lessor, but to the extent
received by Lessor, they shall reduce or discharge, as the case may be, Lessee's
obligation to pay the amounts due to Lessor under Section 16(b) hereof with
respect to such Event of Loss. To the

                                        -12-


extent payment received by Lessor is greater than the amount owed to Lessor as
provided in Section 18(b) hereof, such excess shall be paid to Lessee within 15
days from receipt by the Lessor of said payment; or (ii) if such payments are
received with respect to any loss of or damage to the Equipment other than an
Event of Loss, such payments shall, unless a Default or Event of Default shall
have occurred and be continuing, be paid over to Lessee to reimburse Lessee for
its payment of the costs and expenses incurred by Lessee in replacing or
restoring pursuant to Section 16(a) hereof the part or parts of the Equipment
which suffered such loss or damage.

     17.  GENERAL INDEMNITY.

          Lessee assumes liability for, and shall indemnify, protect save and
keep harmless Lessor and its agents, servants, successors and assigns (an
"Indemnitee") from and against any and all liabilities, obligations, losses,
damages, penalties, claims, actions, suits, costs and expenses, including
reasonable legal expenses, of whatsoever kind  and nature, imposed on, incurred
by or asserted against any Indemnitee, in any way relating to or arising out of
this Lease or the enforcement hereof, or the manufacture, purchase, acceptance,
rejection, ownership, possession, use, selection, delivery, lease, operation,
condition, sale, return or other disposition of the Equipment or any part
thereof (including, without limitation, latent or other defects, whether or not
discoverable by Lessee or any other person, any claim in tort for strict
liability and any claim for patent, trademark or copyright infringement);
provided, however, that Lessee shall not be required to indemnify any Indemnitee
for loss or liability arising from acts or events which occur after the
Equipment has been returned to Lessor in accordance with the Lease, or for loss
or liability resulting solely from the willful misconduct or gross negligence of
such Indemnitee. The provisions of this Section shall survive the expiration or
earlier termination of this Lease.

     18.  EVENTS OF DEFAULT.

          The following event shall each constitute an event of default (herein
called "Event of Default") under this Lease:

          (i)   Lessee shall fail to execute and deliver to Lessor (or Lessor's
agent) the "Delivery Certificate" within twenty-four (24) hours of Turnover of
the Equipment to Lessee.

          (ii)  Lessee shall fail to commence lease payments on the first day of
the month following the Commencement Date, or such other initiation of lease

          (iii) Lessee shall fail to make any payment of rent or other amount
owing hereunder after notice has been given that payment is past due; or

          (iv)  Lessee shall fail to maintain the insurance required by Section
10 hereof or to perform or observe any of the covenants contained in Sections 21
or 22 hereof; or

                                        -13-


          (v)   Lessee shall fail to perform or observe any other covenant,
condition or agreement to be performed or observed by it with respect to this
Lease and such failure shall continue unremedied for 30 days after the earlier
of (a) the date on which Lessee obtains, or should have obtained knowledge of
such failure; or (b) the date on which notice thereof shall be given by Lessor
to Lessee; or

          (vi)  Any representation or warranty made by Lessee herein or in any
document, certificate or financial or other statement now or hereafter furnished
Lessor in connection with this Lease shall prove at any time to have been
untrue, incomplete or misleading in any material respect as of the time when
made; or

          (vii) The entry of a decree or order for relief by a court having

trustee or sequestrator (or similar official) of Lessee or of any substantial
part of its property, or ordering the winding-up or liquidation of its affairs,
and the continuance of any such decree or order unstayed and in effect for a
period of 30 days; or

          (viii) The institution by Lessee or proceedings to be adjudicated a
bankrupt or insolvent, or the consent by it to the institution of bankruptcy or
insolvency proceedings against it, or the commencement by Lessee of a voluntary
proceeding or case under the Federal bankruptcy laws, as now or hereafter
constituted, or any other applicable Federal or state bankruptcy, insolvency or
other similar law, or the consent by it to the filing of any such petition or to
the appointment of or taking possession by a receiver, liquidator, assignee,
trustee, custodian or sequestrator (or other similar official) of Lessee or of
any substantial part of its property, or the making by it of any assignment for
the benefit of creditors or the admission by it of its inability to pay its
debts generally as they become due or its willingness to be adjudicated a
bankrupt or the failure of Lessee generally to pay its debts as they become due
or the taking of corporate action by Lessee in furtherance of any of the
foregoing.

     19.  REMEDIES.  If an Event of Default specified in Subsection 18(vii) or
(viii) above shall occur, then, and in any such event, Lessor shall not be
obligated to purchase or lease any of the Equipment and this Lease shall,
without any declaration or other action by Lessor, be in default. If an Event of
Default, other than an Event of Default specified in Subsection 18(vii) or
(viii) above, shall occur, Lessor may, at its option, declare this Lease to be
in default. Lessee will have ten (10) days from the date Lessor declares the
Lease to be in default to cure the specified Event of Default. At any time after
this Lease is in default under the first sentence of this Section 19, or ten
(10) days after Lessor has declared this Lease to be in default under the second
sentence of this Section 19, and Lessee has not cured

                                        -14-


the Event of Default, Lessor and/or its representative may do any one or more of
the following with respect to all of the Equipment or any part thereof as Lessor
in its sole discretion shall elect, to the extent permitted by applicable law
then in effect:

               (a)  demand that Lessee, and Lessee shall at its expense upon
such demand, return the Equipment promptly to Lessor at such place in the
continental United States of America as Lessor shall specify, or Lessor and/or
its agents, at its option, may with or without entry upon the premises where the
Equipment is located and disable the Equipment, or make the Equipment inoperable
permanently or temporarily in Lessor's sole discretion, and/or take immediate
possession of the Equipment and remove the same by summary proceedings or
otherwise, all without liability for or by reason of such entry or taking of
possession, whether for the restoration of damage to property caused by such
taking or for disabling or otherwise;

               (b)  sell the Equipment at public or private sale, with or
without notice, advertisement or publication, as Lessor may determine, or
otherwise dispose of, hold, use, operate, lease to others or keep idle the
Equipment as Lessor in its sole discretion may determine, all free and clear of
any rights of Lessee and without any duty to account to Lessee with respect to
such action or inaction or for any proceeds with respect thereto;

               (c)  by written notice to Lessee specifying a payment date which
shall be not earlier than 20 days after the date of such notice, demand that
Lessee pay to Lessor, and Lessee shall pay to Lessor, on the payment date
specified in such notice, as liquidated damages for loss of a bargain and not as
a penalty, all accrued and unpaid rent for the Equipment due on all Rent Payment
Dates up to and including the payment date specified in such notice PLUS an
amount (together with interest on such amount at the Late Charge Rate, from the
payment date specified in such notice to the date of actual payment) equal to
the excess, if any, of the Stipulated Loss Value of the Equipment as of the
payment date specified in such notice over the Fair Market Sale Value of the
Equipment as of such date;

               (d)  Lessor may exercise any other right or remedy which may be
available to it under applicable law or proceed by appropriate court action to
enforce the terms hereof or to recover damages for the breach hereof or to
rescind this Lease. Lessor is entitled to recover any amount that fully
compensates the Lessor for any damage to or loss of the Lessor's residual
interest in the leased property caused by the Lessee's default.

     In the event any present value discounting is applied, the discount rate
used shall be the Federal Reserve Board Discount Rate.

     In addition, Lessee shall be liable for any and all unpaid rent and other
amounts due hereunder before or during the exercise of any of the foregoing
remedies and for all reasonable legal fees and other costs and expenses incurred
by reason of the occurrence of any Event of Default or the exercise of Lessor's
remedies with respect thereto, including all reasonable costs and expenses
incurred in connection with the placing of the Equipment in the condition
required by Section 12 hereof.

                                        -15-


     No remedy referred to in this Section 19 is intended to be exclusive, but
each shall be cumulative and in addition to any other remedy referred to herein
or otherwise available to Lessor at law or in equity; and the exercise or
beginning of exercise by Lessor of any one or more of such remedies shall not
preclude the simultaneous or later exercise by Lessor of any or all such other
remedies. No express or implied waiver by Lessor of an Event of Default shall in
any way be, or be construed to be, a waiver of any future or subsequent Event of
Default. To the extent permitted by applicable law, Lessee hereby waives any
rights now or hereafter conferred by statute or otherwise which may require
Lessor to sell or lease or otherwise use the Equipment in mitigation of Lessor's
damages or losses or which may otherwise limit or modify any of Lessor's rights
or remedies under this Lease.

     20.  LESSOR'S RIGHT TO PERFORM.  If Lessee fails to make any payment
required to be made by it hereunder or fails to perform or comply with any of
its other agreements contained herein, Lessor may itself make such payment or
perform or comply with such agreement, and the amount of such payment and the
amount of the reasonable expenses of Lessor incurred in connection with such
payment or the performance of or compliance with such agreement, as the case may
be, together with interest thereon at the Late Charge Rate, shall be deemed to
be additional rent, payable by Lessee within 30 days of notice.

     21.  LOCATION; ASSIGNMENT OR SUBLEASE; TITLE TRANSFER.

          (a)  LESSEE WILL NOT REMOVE THE EQUIPMENT FROM THE LOCATION SPECIFIED
IN SCHEDULE 1 OF EXHIBIT A WITHOUT THE PRIOR WRITTEN CONSENT OF LESSOR, SUCH
CONSENT NOT TO BE UNREASONABLY WITHHELD, EXCEPT REMOVAL OUTSIDE THE CONTINTENTAL
U.S. IS NOT PERMITTED. THE EQUIPMENT SHALL AT ALL TIMES BE IN THE SOLE
POSSESSION AND CONTROL OF LESSEE AND LESSEE WILL NOT, WITHOUT THE PRIOR WRITTEN
CONSENT OF LESSOR, WHICH MAY NOT BE UNREASONABLY WITHHELD, ASSIGN THIS LEASE OR
ANY INTEREST HEREIN OR SUBLEASE OR OTHERWISE TRANSFER ITS INTEREST IN ANY OF THE
EQUIPMENT, AND ANY ATTEMPTED ASSIGNMENT, SUBLEASE OR OTHER TRANSFER BY LESSEE IN
VIOLATION OF THESE PROVISIONS SHALL BE VOID.

          (b)  LESSOR AND LESSEE ACKNOWLEDGE THAT LESSOR (i) MAY TRANSFER ITS
INTEREST IN THE EQUIPMENT TO AN OWNER OTHER THAN LESSOR. LESSOR MAY
CONTEMPORANEOUSLY THEREWITH LEASE THE EQUIPMENT BACK FROM SUCH OWNER, AND (ii)
MAY ASSIGN THIS LEASE. LESSEE HEREBY CONSENTS TO EACH OF THE ABOVE-DESCRIBED
TRANSACTIONS. FURTHER LESSEE DOES HEREBY ACKNOWLEDGE (i) THAT ANY SUCH
ASSIGNMENT BY LESSOR DOES NOT MATERIALLY CHANGE LESSEE'S DUTIES AND OBLIGATIONS
HEREUNDER, (ii) THAT SUCH ASSIGNMENT DOES NOT MATERIALLY INCREASE THE BURDEN OR
RIGHT IMPOSED ON THE LESSEE, AND (iii) THAT THE ASSIGNMENT IS PERMITTED EVEN IF
THE ASSIGNMENT COULD BE DEEMED TO MATERIALLY AFFECT THE INTEREST OF THE LESSEE.

     22.  STATUS CHANGES IN LESSEE.  Lessee will not without thirty (30) days
prior written notice to Lessor, (a) enter into any transaction of merger or
consolidation unless it is the

                                        -16-


surviving corporation or after giving effect to such merger or consolidation its
net worth equals or exceeds that which existed prior to such merger or
consolidation; or (b) change the form of organization of its business; or (c)
change its name or its chief place of business. Lessee may obtain Lessor's prior
written concurrence, which may not be unreasonably withheld, before Lessee may
undertake any actions to (a) liquidate or dissolve or similar action of the
Lessee's organization, or (b) sell, transfer or otherwise dispose of all or any
substantial part of Lessee's assets.

     23.  FURTHER ASSURANCES; FINANCIAL INFORMATION.

          (a)  Lessee will, at its expense, promptly and duly execute and
deliver to Lessor such further documents and assurances and take such further
action as Lessor may from time to time reasonably request in order to establish
and protect the rights, interests and remedies created or intended to be created
in favor of Lessor hereunder, including, without limitation, the execution and
filing of Uniform Commercial Code financing statements covering the Equipment
and proceeds therefrom in the jurisdictions in which the Equipment is located
from time to time. To the extent permitted by applicable law, Lessee hereby
authorizes Lessor to file any such financing statements without the signature of
Lessee.

          (b)  Lessee will qualify to do business and remain qualified in good
standing, in each jurisdiction in which the Equipment is from time to time
located.

          (c)  Lessee will furnish to Lessor as soon as available, but in any
event not later than 90 days after the end of each fiscal year of Lessee, a
consolidated balance sheet of Lessee as at the end of such fiscal year, and
consolidated statements of income and changes in financial position of Lessee
for such fiscal year, all in reasonable detail, prepare in accordance with
generally accepted accounting principles applied on a basis consistently
maintained throughout the period involved. These reports will not be disclosed
to anyone other than the Lessor and/or the Owner as provided in Section 21(b).

     25.  CONDITIONS PRECEDENT:

          (a)  Lessor shall not be obligated to lease the items of Equipment
described herein to Lessee hereunder unless:

               (ii) All representations and warranties of Lessee contained
herein or in any document or certificates furnished Lessor in connection
herewith shall be true and correct on and as of the date of this Lease with the
same force and effect as if made on and as of such date; no Event of Default or
Default shall be in existence on such date or shall occur as a result of the
lease by Lessee of the Equipment specified in Schedule 1 of Exhibit A;

               (iii) In the sole judgment of Lessor, there shall have been no
material adverse change in the financial condition or business of Lessee;

               (iv)  All proceedings to be taken in connection with the
transactions contemplated by this Lease, and all documents incidental thereto,
shall be satisfactory in form and substance to Lessor and its counsel;

               (v)  Lessor shall have received from Lessee, in form and
substance satisfactory to it, such other documents and information as Lessor
shall reasonably request;

               (vi)  All legal matters in connection with the transactions

Product License Agreement attached hereto as Exhibit B (the "License
Document"). Lessor has arranged for the Equipment manufacturer to grant Lessee a

Document. The original license fee is contained in the lease rate. To avail
itself of the license grant, Lessee must execute the License Document, upon
Commencement of the Lease. The option to obtain a fully paid up license as
provided in Article 2 of the License Document may be exercised by the Lessee and
the payment made directly to the equipment manufacturer named in the License

                                        -18-


Document.

     27.  LIMITATION OF LIABILITY.

          LESSOR SHALL NOT BE LIABLE FOR LOST PROFITS OR REVENUE, SPECIAL,
INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES OF ANY NATURE OR FROM
ANY CAUSE WHETHER BASED IN CONTRACT OR TORT, INCLUDING NEGLIGENCE, OR OTHER
LEGAL THEORY EVEN IF LESSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES. LESSEE HEREBY AGREES THAT LESSOR WILL NOT BE LIABLE FOR ANY LOST
PROFITS OR REVENUE OR FOR ANY CLAIM OR DEMAND AGAINST LESSEE BY ANY OTHER
PARTY.

     28.  MISCELLANEOUS.

          (a)  Any provision of this Lease which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provisions in any other jurisdiction. To the extent
permitted by applicable law, Lessee hereby waives any provision of law which
renders any provision hereof prohibited or unenforceable in any respect.

          (b)  No terms or provisions of this Lease may be changed, waived,
discharged or terminated orally, but only by an instrument in writing signed by
the party against which the enforcement of the change, waiver, discharge or
termination is sought. No delay or failure on the part of Lessor to exercise any
power or right hereunder shall operate as a waiver thereof, nor as an
acquiescence in any default, nor shall any single or partial exercise of any
power or right preclude any other or further exercise thereof, or the exercise
of any other power or right. After the occurrence of any Default or Event of
Default, the acceptance by Lessor of any payment of rent or other sum owed by
Lessee pursuant hereto shall not constitute a waiver by Lessor of such Default
or Event of Default, regardless of Lessor's knowledge or lack of knowledge
thereof at the time of acceptance of any such payment, and shall not constitute
a reinstatement of this Lease, if this Lease shall have been declared in default
by Lessor pursuant to Section 18 hereof or otherwise, unless Lessor shall have
agreed in writing to reinstate the Lease and to waive the Default or Event of
Default.

     In the event Lessee tenders payment to Lessor by check or draft containing
a qualified endorsement purporting to limit or modify Lessee's liability or
obligations under this Lease, such qualified endorsement shall be of no force
and effect even if Lessor processes the check or draft for payment.

                                        -19-


          (c)  This Lease with exhibits contains the full, final and exclusive
statement of the agreement between Lessor and Lessee relating to the lease of
the Equipment.

          (d)  This Lease shall constitute an agreement of an operating lease,
and nothing herein shall be construed as conveying to Lessee any right, title or
interest in the Equipment except as Lessee only.

          (e)  This Lease and the covenants and agreements contained herein
shall be binding upon, and inure to the benefit of, Lessor and its successors
and assigns and Lessee and, to the extent permitted by Section 21 hereof, its
successors and assigns.

          (f)  The headings of the Sections are for convenience of reference
only, are not a part of this Lease and shall not be deemed to affect the meaning
or construction of any of the provisions hereof.

          (g)  This Lease may be executed by the parties hereto on any number of
separate counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts shall together constitute but one and the
same instrument.

Florida and shall be governed by and construed under and in accordance with the
laws of the State of Florida as if both parties were residents of Florida.

action, suit, or proceeding arising out of or in any way in connection with this
Lease shall be instituted or brought in the courts of the State of Florida, or
the United States Courts for the District of Florida, and by execution and
