        rapid than straight line over the Lease Term.
    (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 his 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.

                                     - 4 -



    (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
    property of Lessor.
13. INSPECTION.
    Upon prior notice, Lessor or its authorized representative may at any
    reasonable time or times inspect the Equipment when it deems it necessary to
    protect its interest therein.
14. IDENTIFICATION.
    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 they 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; 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 occurred 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 an 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 events 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
    payments as specified in Section 5 of this 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
    (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

                                     - 5 -



    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
    jurisdiction in respect of Lessee, adjudging Lessee a bankrupt or

    reorganization, arrangement, adjustment or composition of or in respect of
    Lessee in an involuntary 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 appointing a
    receiver, liquidator, assignee, custodian, 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 of 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.  At any time after this Lease is in default under
    the first sentence of this Section 19, Lessor has declared this Lease to be
    in default under the second sentence of this Section 19, 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 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 damanges 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. 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 statue 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
     CONTINENTAL U.S. IS NOT PERMITTED. THE EQUIPMENT SHALL AT 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 ANY 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 OBLIGATION 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 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 must obtain Lessor's prior written concurrence 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 [illegible copy] 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
     Lessor, 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, prepared in accordance with general 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/owner 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:

        (i) Such Uniform Commercial Code financing statements covering
        Equipment and proceeds therefrom and landlord and/or mortgagee
        waivers or disclaimers and/or severance agreements with respect to
        the items of Equipment covered by this Lease as Lessor shall deem
        necessary or desirable in order to perfect and protect its interests
        therein shall have been duly executed and filed, at Lessee's expense,
        in such public offices as Lessor shall direct;

        (ii)  All representations and warranties of Lessee contained herein or
        in any document or certificate furnished Lessor in connection
        herewith shall be true and correct on and as of the date of this

        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;

        material adverse change in the financial condition of business or
        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
        contemplated by this Lease shall be satisfactory to Lessor's counsel;
        and

        (vii) No Change in Tax Law, which in the sole judgment of Lessor
        would adversely affect Lessor's Economics, shall have occurred or
        shall appear, in Lessor's good faith judgment, to be imminent.

26.  SOFTWARE LICENSE.
     Reference is made to the form of DCO Software License Agreement attached
     hereto as Exhibit B (the "License Document"). Lessor has arranged for
     the Equipment manufacturer to grant Lessee a license to use the Software
     as defined in the License Document in conjunction with the equipment
     leased hereunder in accordance with the


                                     -7-


     terms of the License 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 Document.
     "Buyer" and "Licensee" as used in the License Document are synonymous
     with lessee.

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
     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.

     (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.

     (h) This Lease is deemed made and entered into in the State of 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.

     (i) Lessee hereby irrevocably consents and agrees that any legal 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 delivery of this Lease, Lessee hereby irrevocably accepts
     and submits to, for itself and in respect of its property, generally and
     unconditionally, the non-exclusive jurisdiction of any such court, and
     to all proceedings in such courts. Lessee irrevocably consents to
     service of any summons and/or legal process by registered or certified
     United States mail, postage prepaid, to Lessee at the address set forth
     in Section 24 hereof, such method of service to constitute, in every
     respect, sufficient and effective service of process in any legal action
     or proceeding. Nothing in this Lease shall affect the right to service
     of process in any other manner permitted by law or limit the right of
     Lessor to bring actions, suits or proceedings in the court of any other
     jurisdiction. Lessee further agrees that final judgment against it in
     any such legal action, suit or proceeding shall be conclusive and may be
     enforced in any other jurisdiction, within or outside the United States
     of America, by suit on the judgment, a certified or exemplified copy of
     which shall be conclusive evidence of the fact and the amount of the
     liability.

     IN WITNESS WHEREOF, Lessor and Lessee have each caused this Lease to be
duly executed as of the day and year first above written and by its signature
below Lessee expressly acknowledges that this Lease may not be modified
unless done so in writing signed by each of the parties hereto or their
successors in interest.
