                    -------------                                      -------
3.5, each Lessee agrees to pay when due all real estate taxes, personal property

taxes, gross sales taxes, including any sales or lease tax imposed upon the
rental payments hereunder or under a sublease, occupational license taxes, water
charges, sewer charges, assessments of any nature and all other governmental
impositions and charges of every kind and nature whatsoever (the "tax(es)"),
                                                                  -------
when the same shall be due and payable without penalty or interest; provided,

however, that this Section shall not apply to any of the taxes covered by the
-------
exclusion described in Section 7.4(b) of the Master Agreement.  It is the
intention of the parties hereto that, insofar as the same may lawfully be done,
Lessor shall be, except as specifically provided for herein, free from all
expenses in any way related to the Leased Properties and the use and occupancy
thereof.  Any tax relating to a fiscal period of any taxing authority falling
partially within and partially outside the Lease Term, shall be apportioned and
adjusted between Lessor and the related Lessee.  Each Lessee covenants to
furnish Lessor and the Agent, upon the Agent's written request, within forty-
five (45) days after the last date when any tax must be paid by such Lessee as
provided in this Section 3.6, copies of official receipts of the appropriate
                 -----------
taxing, authority or other proof satisfactory to Lessor, evidencing the payment
thereof.

     So long as no Event of Default has occurred and is continuing, the related
Lessee may defer payment of a tax so long as the validity or the amount thereof
is contested by such Lessee with diligence and in good faith; provided, however,
                                                              --------  -------
that such Lessee shall pay the tax in sufficient time to prevent delivery of a
tax deed.  Such contest shall be at the related Lessee's sole cost and expense.
Each Lessee covenants to indemnify and save harmless Lessor, the Agent and each
Lender from any actual and reasonable costs or expenses incurred by Lessor, the
Agent or any Lender as a result of such contest, which indemnification shall
survive the termination of this Lease; provided that neither the Agent nor any
                                       --------
Lender shall be entitled to claim any indemnity against any Lessee pursuant to
this sentence with respect to any Construction Land Interest during the
Construction Term therefor.

     Section III.7  Utility Charges.  Each Lessee agrees to pay or cause to be
                    ---------------
paid as and when the same are due and payable all charges for gas, water, sewer,
electricity, lights, heat, power, telephone or other communication service and
all other utility services used, rendered or supplied to, upon or in connection
with the Leased Properties leased by it.

     During the Lease Term, Lessor's interest in the Leased Properties,
including the Equipment, the Building(s) (whether or not completed) and the
Land, is demised and let by Lessor "AS IS" subject to (a) the rights of any
parties in possession thereof, (b) the state of the title thereto existing at
the time Lessor acquired its interest in the Leased Properties, (c) any state of
facts which an accurate survey or physical inspection might show (including the
survey delivered on the related Closing Date), (d) all Applicable Law, and (e)
any violations of Applicable Law which may exist upon or subsequent to the
commencement of the Lease Term.  EACH LESSEE ACKNOWLEDGES THAT, ALTHOUGH LESSOR
WILL OWN AND HOLD TITLE TO THE LEASED PROPERTIES, LESSOR IS NOT A MANUFACTURER
OF, OR DEALER IN ANY LEASED PROPERTY, AND IS NOT RESPONSIBLE FOR THE DESIGN,
DEVELOPMENT, BUDGETING AND CONSTRUCTION OF THE BUILDING(S) OR ANY ALTERATIONS.
NEITHER LESSOR, THE AGENT NOR ANY LENDER HAS MADE OR SHALL BE DEEMED TO HAVE
MADE ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, OR SHALL BE DEEMED TO
HAVE ANY LIABILITY WHATSOEVER AS TO THE VALUE, MERCHANTABILITY, TITLE,
HABITABILITY, CONDITION, DESIGN, OPERATION, OR FITNESS FOR USE OF THE LEASED
PROPERTIES (OR ANY PART THEREOF), OR ANY OTHER REPRESENTATION OR WARRANTY
WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO THE LEASED PROPERTIES (OR ANY
PART THEREOF), ALL SUCH WARRANTIES BEING HEREBY DISCLAIMED, AND NEITHER LESSOR,
THE AGENT NOR ANY LENDER SHALL BE LIABLE FOR ANY LATENT, HIDDEN, OR PATENT
DEFECT THEREIN OR THE FAILURE OF ANY LEASED PROPERTY, OR ANY PART THEREOF, TO
COMPLY WITH ANY APPLICABLE LAW, except that Lessor hereby represents and
warrants that each Leased Property is and shall be free of Lessor Liens.  As
between Lessor and the Lessees, each related Lessee has been afforded full
opportunity to inspect each Leased Property, is satisfied with the results of
its inspections of such Leased Property and is entering into this Lease solely
on the basis of the results of its own inspections and all risks incident to the
matters discussed in the two preceding sentences, as between Lessor, the Agent
or the Lenders on the one hand, and the Lessees, on the other, are to be borne
by the Lessees, except for the foregoing representation and warranty of Lessor
relative to the absence of Lessor Liens.  The provisions of this Article IV have
                                                                 ----------
been negotiated, and, except to the extent otherwise expressly stated, the
foregoing provisions are intended to be a complete exclusion and negation of any

law now or hereafter in effect, or otherwise.

                     LIENS; EASEMENTS; PARTIAL CONVEYANCES
                     -------------------------------------

     Each Lessee shall, within thirty (30) days following knowledge thereof,
discharge or bond over any Lien on or with respect to any Leased Property, the
title thereto, or any interest therein, including any Liens which arise out of
the possession, use, occupancy, construction, repair or rebuilding of any Leased
Property or by reason of labor or materials furnished or claimed to have been
furnished to a Lessee, or any of its contractors or agents or Alterations
constructed by a Lessee, except, in all cases, Permitted Liens or Lessor Liens.

     Notwithstanding the foregoing paragraph, at the request of a Lessee, Lessor
shall, from time to time during the Lease Term and upon reasonable advance
written notice from such Lessee, and within fifteen (15) days of receipt of the
materials specified in the next succeeding sentence, consent to and join in any
(i) grant of easements, licenses, rights of way and other rights in the nature
of easements, including, without limitation, utility easements to facilitate
Lessees' use, development and construction of the Leased Properties, (ii)
release or termination of easements, licenses, rights of way or other rights in
the nature of easements which are for the benefit of the Land or the Building(s)
or any portion thereof, (iii) dedication or transfer of portions of the Land,
not improved with a Building, for road, highway or other public purposes, (iv)
execution of agreements for ingress and egress and amendments to any covenants
and restrictions affecting the Land or the Building(s) or any portion thereof
and (v) request to any Governmental Authority for platting or subdivision or
replatting or resubdivision approval with respect to the Land or any portion
thereof or any parcel of land of which the Land or any portion thereof forms a
part or a request for rezoning or any variance from zoning or other governmental
requirements.  Lessor's obligations pursuant to the preceding sentence shall be
subject to the requirements that:

          (a)  any such action shall be at the sole cost and expense of the
requesting Lessee and such Lessee shall pay all actual and reasonable out-of-
pocket costs of Lessor, the Agent and any Lender in connection therewith
(including, without limitation, the reasonable fees of attorneys, architects,
engineers, planners, appraisers and other professionals reasonably retained by
Lessor, the Agent or any Lender in connection with any such action),

          (b)  the requesting Lessee shall have delivered to Lessor and Agent a
certificate of a Responsible Officer of such Lessee stating that

               (i) such action will not cause any Leased Property, the Land or
     any Building or any portion thereof to fail to comply in any material
     respect with the provisions of this Lease or any other Operative Documents
     or any applicable IDB Documentation, or in any material respect with
     Applicable Law; and

               (ii) such action will not materially reduce the Fair Market Sales
     Value, utility or useful life of any Leased Property, the Land or any
     Building nor Lessor's interest therein; and

          (c)  in the case of any release or conveyance, if Lessor, the Agent or
any Lender so reasonably requests, the requesting Lessee will cause to be issued
and delivered to Lessor and the Agent by the Title Insurance Company an
endorsement to the Title Policy which shall revise the insured legal description
to delete the released property, and shall indicate that the Title Policy is in
full force and effect at the original policy amount.

     In addition to the foregoing, the related Lessee may arrange for a sale of
a portion of the Leased Property located at the southeast corner of N.W. 108/th/
Avenue and N.W. 91/st/ Terrace, Miami, Florida and Lessor shall execute such
documents and instruments as may be requested by such Lessee to effect such
sale, provided that all of the following conditions are met: (i) after giving
      --------
effect to such sale, the Leased Property complies with all Applicable Laws
(including all zoning laws and regulations) and all applicable insurance
requirements, (ii) after giving effect to such sale, such Leased Property has
available all services of public facilities and other utilities, together with
all means of egress and ingress, to and from such Leased Property, necessary for
the use and operation of such Leased Property for its intended purpose, (iii)
the net proceeds of such sale shall be at least equal to the diminution in the
Fair Market Sales Value of such Leased Property resulting from such sale, and
shall be applied to reduce the Funded Amounts (on a pro rata basis, among the
Funding Parties) related thereto, (iv) such sale shall be on an "as is, where
is" basis, without representation or recourse on the part of Lessor, (v) the
related Lessee shall pay, or shall promptly reimburse the Agent and the Funding
Parties for, all out of pocket costs and expenses, including legal fees and
disbursements, incurred by any of them in connection with such sale, and (vi)
the related Lessee shall deliver a certificate of a Responsible Officer to the
effect that the foregoing conditions have been satisfied and such other
certificates and documents as the Agent or any Funding Party shall reasonably
request.

its own expense, shall at all times (a) maintain each Leased Property leased by

make repairs at the expense of Lessor, the Agent or any Lender pursuant to any
Applicable Law or other agreements or otherwise.  NEITHER LESSOR, THE AGENT NOR
ANY LENDER SHALL BE PERSONALLY LIABLE TO ANY LESSEE OR TO ANY CONTRACTORS,
SUBCONTRACTORS, LABORERS, MATERIALMEN, SUPPLIERS OR VENDORS FOR SERVICES

this Lease.

                                      ---

     Each Lessee may use each Leased Property leased by it or any part thereof
for any lawful purpose, and in a manner consistent with the standards applicable
to properties of a similar nature in the geographic area in which such Leased
Property is located, provided that such use does not materially adversely affect
                     --------
the Fair Market Sales Value, utility, remaining useful life or residual value of
such Leased Property, and does not materially violate or conflict with, or
constitute or result in a material default under, any Applicable Law or any
insurance policy required hereunder.  In the event that any use of any of the
Leased Property changes the character or original intended use of such Leased
Property and the Lessees do not purchase the Leased Properties at the end of the
Lease Term, the related Lessee, upon request of Lessor, shall restore such
Leased Property to its general character and intended use on the Closing Date or
Completion Date therefor, ordinary wear and tear excepted.  No Lessee shall
commit or permit any waste of any Leased Property or any material part thereof.

          The provisions of this Article VIII shall apply to Leased Properties
                                 ------------
that are not then subject to the Construction Agency Agreement.  For any Leased
Property subject to the Construction Agency Agreement, the Lessee shall maintain
insurance in accordance with Section 2.9 of the Construction Agency Agreement.

          (a)  At any time during which any part of any Building or any
Alteration is under construction and as to any part of any Building or any
Alteration under construction, the related Lessee shall maintain, or cause to be
maintained, at its sole cost and expense, as a part of its blanket policies or
otherwise, "all risks" non-reporting completed value form of builder's risk
insurance.

          (b)  During the Lease Term, each Lessee shall maintain, at its sole
cost and expense, as a part of its blanket policies or otherwise, insurance
against loss or damage to any Building or any item of equipment included in the

favorable than insurance covering other similar properties or equipment owned or
leased by a Lessee, but in no event less than the replacement cost of such
Building or item of equipment included in the Leased Property, as the case may
be, from time to time.

          (c)  During the Lease Term, each Lessee shall maintain, at its sole
cost and expense, commercial general liability insurance with respect to such
Lessee's use, operation and

                                      10

occupancy of the Leased Properties. Such insurance shall be on terms and in
amounts that are no less favorable than insurance maintained by a Lessee or its
Affiliates with respect to similar properties or equipment that it owns or
leases, but in no event less than $1,000,000 general liability, plus $5,000,000
liability umbrella coverage, per occurrence. Such insurance policies shall also
provide that each Lessee's insurance shall be considered primary insurance.
Nothing in this Article VIII shall prohibit
                ------------
Lessor, the Agent or any Lender from carrying at its own expense other insurance
on or with respect to the Leased Properties, provided that any insurance carried
                                             --------
by Lessor, the Agent or any Lender shall not prevent any Lessee from carrying
the insurance required hereby.

          (d) Each policy of insurance maintained by a Lessee pursuant to

clauses (a) and (b) of this Article VIII shall provide that all insurance
-----------     ---         ------------
proceeds in respect of any loss or occurrence shall be adjusted by, and all
insurance proceeds shall be paid to, such Lessee, except if, and for so long as
an Event of Default exists, all losses shall be adjusted solely by, and all
insurance proceeds shall be paid solely to, the Agent (or Lessor if the Loans
have been fully paid) for application pursuant to this Lease.

          (e) On the Closing Date for each parcel of Land and on each
anniversary of the related policy date each Lessee shall furnish Lessor with
certificates showing the insurance required under this Article VIII to be in

Such certificates shall include a provision for thirty (30) days' advance
written notice by the insurer to Lessor and the Agent in the event of
cancellation or expiration or nonpayment of premium with respect to such
insurance, and shall include a customary breach of warranty clause.  Each Lessee
shall provide evidence to Lessor and the Agent that each insurance policy
required by this Article VIII has been renewed or replaced prior to the
                 ------------
scheduled expiration date therefor.

          (f) Each policy of insurance maintained by a Lessee pursuant to this

Property or (B) renders restoration and rebuilding of the related Leased
Property impossible or impractical, and with respect to which such Lessee has
determined not to repair

rebuild such Leased Property pursuant to Section 10.4. If an Event of Taking
                                         ------------
shall occur, the related Lessee shall purchase the affected Leased Property

Construction Agency Agreement with respect to remarketing). Upon Lessor's
receipt of such Leased Property Balance on such date, Lessor shall cause
Lessor's interest in such Leased Property, and in all condemnation proceeds
related thereto, to be conveyed to the related Lessee in accordance with and
subject to the provisions of Section 14.4 hereof (provided that such conveyance
                             ------------
shall be subject to all rights of the condemning authority); upon completion of
such purchase (or payment of the Construction Failure Payment, as the case may
be), but not prior thereto, this Lease with respect to such Leased Property and
all obligations hereunder with respect to such Leased Property shall terminate,
except with respect to obligations and liabilities hereunder, actual or
contingent, that have arisen or relate to events occurring on or prior to such

     ------------
out-of-pocket costs incurred by Lessor in collecting such Awards, received or

complete the same prior to the Lease Termination Date, and will cause the
condition set forth in Section 3.5 (c) of the Master Agreement to be fulfilled
with respect to such restoration and rebuilding prior to the Lease Termination
Date, regardless of whether insurance proceeds received as a result of such
Casualty are sufficient for such purpose.

of the related Building and the Land.  All actual and reasonable out-of-pocket
costs of such inspections incurred by Lessor, the Agent or any Lender will be
paid by the related Lessee promptly after written request.  No such inspection
shall unreasonably interfere with the related Lessee's operations or the
operations of any other occupant of such Leased Property.  None of the

and none of the inspecting parties shall incur any liability or obligation by
reason of making or not making any such inspection or inquiry.

     Section XIII.1 Remedies. Upon the occurrence and during the continuance of
                    --------
any Event of Default, Lessor may do one or more of the following as Lessor in
its sole discretion shall determine, without limiting any other right or remedy
Lessor may have on account of such Event of Default; provided that, with respect
                                                     --------
to any Leased Property subject to the Construction Agency Agreement, the
Lessor's remedies with respect thereto shall be limited to those set forth in
Section 5.3 of the Construction Agency Agreement.
-----------

     (a)  Lessor may, by notice to Hughes, rescind or terminate this Lease as of
the date specified in such notice; however, (A) no reletting, reentry or taking
of possession of any Leased Property by Lessor will be construed as an election
on Lessor's part to terminate this Lease unless a written notice of such
intention is given to Hughes, (B) notwithstanding any reletting, reentry or
taking of possession, Lessor may at any time thereafter elect to terminate this
Lease for a continuing Event of Default, and (C) no act or thing done by Lessor
or any of its agents, representatives or employees and no agreement accepting a
surrender of any Leased Property shall be valid unless the same be made in
writing and executed by Lessor;

     (b)  Lessor may (i) demand that the Lessees, and the Lessees shall upon the
written demand of Lessor, return the Leased Properties promptly to Lessor in the
manner and condition required by, and otherwise in accordance with all of the
provisions of, Articles VI and XIV hereof as if the Leased Properties were being
               -----------     ---
returned at the end of the Lease Term, and Lessor shall not be liable for the
reimbursement of any Lessee for any costs and expenses incurred by such Lessee
in connection therewith and (ii) without prejudice to any other remedy which
Lessor may have for possession of the Leased Properties, and to the extent and
in the manner permitted by Applicable Law, enter upon any Leased Property and
take immediate possession of (to the exclusion of the related Lessee) any Leased
Property or any part thereof and expel or remove the related Lessee and any
other person who may be occupying such Leased Property, by summary proceedings
or otherwise, all without liability to any Lessee for or by reason of such entry
or taking of possession, whether for the restoration of damage to property
caused by such taking or

                                      21
<PAGE>

otherwise and, in addition to Lessor's other damages, the Lessees shall be
responsible for the actual and reasonable costs and expenses of reletting,
including brokers' fees and the reasonable out-of-pocket costs of any
alterations or repairs made by Lessor;

     (c)  Lessor may (i) sell all or any part of the Leased Properties at public
or private sale, as Lessor may determine, free and clear of any rights of any
Lessee and without any duty to account to any Lessee with respect to such action
or inaction or any proceeds with respect thereto (except to the extent required
by clause (ii) below if Lessor shall elect to exercise its rights thereunder) in
   -----------
which event the Lessees' obligation to pay Basic Rent hereunder for periods
commencing after the date of such sale shall be terminated or proportionally
reduced, as the case may be; and (ii) if Lessor shall so elect, demand, by
written notice to Hughes, that the Lessees pay as liquidated damages for loss of
a bargain and not as a penalty (the parties agreeing that the Lessor's actual
damages would be difficult to predict, but the aforementioned liquidated damages
represent a reasonable approximation of such amount) an amount equal to (A) the
excess of the sum of (1) all Rent due and unpaid as of the date of such payment,
plus (2) the Permitted Lease Balances for all of the Leased Properties over (B)
the net proceeds of such sale (that is after deducting all costs, taxes and
expenses incurred by Lessor, the Agent or any Lender incident to such
conveyance);

     (d)  Lessor may, at its option, not terminate this Lease, and continue to
collect all Basic Rent, Supplemental Rent, and all other amounts (including,
without limitation, the Funded Amount) due Lessor (together with all costs of
collection) and enforce the Lessees' obligations under this Lease as and when
the same become due, or are to be performed, and at the option of Lessor, upon
any abandonment of any Leased Property by Lessee or re-entry of same by Lessor,
Lessor may, in its sole and absolute discretion, elect not to terminate this
Lease with respect thereto and may make such reasonable alterations and
necessary repairs in order to relet such Leased Property, and relet such Leased
Property or any part thereof for such term or terms (which may be for a term
extending beyond the term of this Lease) and at such rental or rentals and upon
such other terms and conditions as Lessor in its reasonable discretion may deem
advisable; and upon each such reletting all rentals actually received by Lessor
from such reletting shall be applied to the Lessees' obligations hereunder in
such order, proportion and priority as Lessor may elect in Lessor's sole and
absolute discretion.  If such rentals received from such reletting during any
Rent Period are less than the Rent to be paid during that Rent Period by the
Lessees hereunder, the Lessees shall pay any deficiency, as reasonably
calculated by Lessor, to Lessor on the Payment Date for such Rent Period;

     (e)  Lessor may exercise any other right or remedy that may be available to
it under Applicable Law, or proceed by appropriate court action (legal or
equitable) to enforce the terms hereof or to recover damages for the breach
hereof.  Separate suits may be brought to collect any such damages for any Rent
Period(s), and such suits shall not in any manner prejudice Lessor's right to
collect any such damages for any subsequent Rent Period(s), or Lessor may defer
any

                                      22
<PAGE>

such suit until after the expiration of the Lease Term, in which event such suit
shall be deemed not to have accrued until the expiration of the Lease Term; or

     (f)  Lessor may retain and apply against Lessor's damages all sums which
Lessor would, absent such Event of Default, be required to pay to, or turn over
to, a Lessee pursuant to the terms of this Lease.

     Section XIII.2 Remedies Cumulative; No Waiver; Consents. To the extent
                    ----------------------------------------
permitted by, and subject to the mandatory requirements of, Applicable Law, each
and every right, power and remedy herein specifically given to Lessor or
otherwise in this Lease shall be cumulative and shall be in addition to every
other right, power and remedy herein specifically given or now or hereafter
existing at law, in equity or by statute, and each and every right, power and
remedy whether specifically herein given or otherwise existing may be exercised
from time to time and as often and in such order as may be deemed expedient by
Lessor, and the exercise or the beginning of the exercise of any power or remedy
shall not be construed to be a waiver of the right to exercise at the same time
or thereafter any right, power or remedy.  No delay or omission by Lessor in the
exercise of any right, power or remedy or in the pursuit of any remedy shall
impair any such right, power or remedy or be construed to be a waiver of any
default on the part of any Lessee or to be an acquiescence therein.  Lessor's
consent to any request made by any Lessee shall not be deemed to constitute or
preclude the necessity for obtaining Lessor's consent, in the future, to all
similar requests.  No express or implied waiver by Lessor of any Event of
Default shall in any way be, or be construed to be, a waiver of any future or
subsequent Potential Event of Default or Event of Default.  To the extent
permitted by Applicable Law, each Lessee hereby waives any rights now or
hereafter conferred by statute or otherwise that may require Lessor to sell,
lease or otherwise use any Leased Property or part thereof in mitigation of
Lessor's damages upon the occurrence of an Event of Default or that may
otherwise limit or modify any of Lessor's rights or remedies under this Article
                                                                        -------

                    ---------------------------------
Event of Default, until such time as Lessor commences material preparations for
the sale or re-lease of the Leased Properties, the Lessees may purchase all, but
not less than all, of the Leased Properties for a purchase price equal to (A)
the Lease Balance, including any amounts due pursuant to Section 7.5 of the
Master Agreement, if such purchase occurs prior to the EBO Date and (B) the
greater of (i) the Lease Balance, including any amounts due pursuant to Section
7.5 of the Master Agreement and (ii) the aggregate Fair Market Sales Value of
the Leased Properties, if such purchase occurs on or after the EBO Date; such

provided, however if Lessor used commercial reasonable standards in determining

that such Limited Event of Default occurred, then the Lessor shall be entitled
to exercise any of the remedies set forth in Section 13.1; and provided, further
                                             ------------      --------  -------

conditions and provisions set forth in this Article XIV, each Lessee shall have

Lessor shall convey to each Lessee, by special warranty deed and bill of sale,

the Lessees may elect to purchase all, but not less than all, of the Leased
Properties on the Lease Termination Date for a price equal to the Fair Market
Sales Value therefor as of the Lease Termination Date.  The Lessees may exercise
such option by giving the Lessor irrevocable notice of such exercise at least
twelve (12) months prior to the Lease Termination Date.  In the event that the
Lessees do not

paid in full) the Lease Balance or Leased Property Balance, or the Fair Market
Sales Value, as applicable, plus any amount due pursuant to Section 7.5 of the
Master Agreement as a result of such purchase by wire transfer of immediately
available funds, (iii) Lessor will execute and deliver to the related Lessee
such other documents, including releases, affidavits, termination agreements and
termination statements, as may be legally required or as may be reasonably
requested by Lessee in order to effect such conveyance, free and clear of Lessor
Liens and the Liens of the Operative Documents and (iv) if such Leased Property

Lessee shall pay any amounts due with respect thereto under such Ground Lease.

     (b)  Each Lessee shall, at such Lessee's sole cost and expense, obtain all
required governmental and regulatory approval and consents and in connection
therewith shall make such filings as required by Applicable Law; in the event
that Lessor is required by Applicable Law to take any action in connection with
such purchase and sale, the Lessees shall pay prior to transfer all reasonable
out-of-pocket costs incurred by Lessor in connection therewith.  Without
limiting the foregoing, all costs incident to such conveyance, including,
without limitation, each Lessee's attorneys' fees, Lessor's attorneys' fees,

     more than one hundred eighty (180) days prior to the Lease Termination
     Date.  Such environmental assessment shall be prepared by an environmental
     consultant selected by the related Lessee and reasonably satisfactory to
     the Required Funding Parties, shall be in form, detail and substance
     reasonably satisfactory to the Required Funding Parties, and shall
     otherwise indicate no degradation in environmental conditions beyond those
     described in the related Environmental Audit for which corrective action is
     required by Applicable Law and shall not include a recommendation for
     further investigation to make such determination.

          (b)  On the date of Lessees' surrender, each of the Construction
     Conditions shall have been timely satisfied and no Event of Default or
     Potential Event of Default shall exist, and thereafter, no Event of Default
     or Potential Event of Default shall exist under this Lease.

          (c)  Each Lessee shall have completed in all material respects all
     Alterations, restoration and rebuilding of the Leased Properties leased by
     it pursuant to Sections 6.1, 6.2, 10.3 and 10.4 (as the case may be) and
                    ------------  ---  ----     ----
     shall have fulfilled in all material respects all of the conditions and
     requirements in connection therewith pursuant to said Sections, in each
                                                           --------
     case by the date on which the Lessees' surrender the Leased Properties,
     regardless of whether the same shall be within such Lessee's control.

          (d)  Upon request by the Agent, each Lessee shall promptly provide any
     maintenance records relating to each Leased Property leased by it to
     Lessor, the Agent and any potential purchaser, and shall otherwise do all
     things necessary to deliver possession of such Leased Property to the
     potential purchaser at the appropriate closing date.  Each Lessee shall
     allow Lessor, the Agent and any potential purchaser reasonable access
     during normal business hours to any Leased Property for the purpose of
     inspecting the same.

          (e)  In connection with any such sale of the Leased Properties, each
     Lessee will provide to the purchaser all customary "seller's" indemnities
     reasonably requested by the potential purchaser (taking into account the
     location and nature of the Leased Properties), representations and
     warranties regarding title, absence of Liens (except Lessor Liens) and the
     condition of the Leased Properties.  Each Lessee shall fulfill all of the
     requirements set forth in clause (b) of Section 14.4, and such requirements
                               ----------    ------------
     are incorporated herein by

                                      26
<PAGE>

     reference. As to Lessor, any such sale shall be made on an "as is, with all
     faults" basis without representation or warranty by Lessor, other than the
     absence of Lessor Liens.

          (f)  Each Lessee shall, on such Lease Termination Date, and at its own
     cost, transfer possession of the Leased Properties leased by it to the
     Lessor or the independent purchaser thereof, in each case by surrendering
     the same into the possession of Lessor or such purchaser, as the case may
     be, free and clear of all Liens other than Lessor Liens, in as good
     condition as it was on the Completion Date therefor in the case of new
     Construction, or the Funding Date (as modified by Alterations permitted by
     this Lease), ordinary wear and tear excepted, and in compliance in all
     material respects with Applicable Law.

          (g)  Each Lessee shall, on and within a reasonable time before and
     after the Lease Termination Date, cooperate with Lessor and the independent
     purchaser of any Leased Property leased by such Lessee in order to
     facilitate the ownership and operation by such purchaser of such Leased
     Property after the Lease Termination Date, which cooperation shall include
     the following, all of which such Lessee shall do on or before the Lease
     Termination Date or as soon thereafter as is reasonably practicable:

     (to the extent assignable) necessary for the operation and maintenance of

     necessary Governmental Action.  The obligations of such Lessee under this
     Article XIV shall survive the expiration or termination of this Lease.

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

     After any repossession of any Leased Property (whether or not this Lease
has been terminated), the related Lessee, at its expense and so long as such
removal of such trade fixture, personal property or equipment shall not result
in a violation of Applicable Law, shall, within a reasonable time after such
repossession or within ninety (90) days after such Lessee's receipt of Lessor's
written request (whichever shall first occur), remove all of such Lessee's trade
fixtures, personal property and equipment from such Leased Property (to the
extent that the same can be readily removed from such Leased Property without
causing material damage to such Leased Property); provided, however, that such
                                                  --------  -------
Lessee shall not remove any such trade fixtures, personal property or equipment
that has been financed by Lessor under the Operative Documents or otherwise
constituting Leased Property (or that constitutes a replacement of such
property).  Any of a Lessee's trade fixtures, personal property and equipment
not so removed by such Lessee within such period shall be considered abandoned
by such Lessee, and title thereto shall without

further act vest in Lessor, and may be appropriated, sold, destroyed or
otherwise disposed of by Lessor without notice to any Lessee and without
obligation to account therefor and the related Lessee will pay Lessor, upon
written demand, all reasonable costs and expenses incurred by Lessor in
removing, storing or disposing of the same and all costs and expenses incurred
by Lessor to repair any damage to such Leased Property caused by such removal.
Each Lessee will immediately repair at its expense all damage to such Leased
Property caused by any such removal (unless such removal is effected by Lessor,
in which event such Lessee shall pay all reasonable costs and expenses incurred
by Lessor for such repairs). Lessor shall have no liability in exercising
Lessor's rights under this Article XV, nor shall Lessor be responsible for any
                           ----------
loss of or damage to any Lessee's personal property and equipment.

                                 ARTICLE XVI.
                          RIGHT TO PERFORM FOR LESSEE
                          ---------------------------

     If any Lessee shall fail to perform or comply with any of its agreements
contained herein and either such failure shall continue for a period of 10 or
more days after notice to Hughes or to such Lessee by Lessor or the Agent or
such failure has resulted in immediate material danger to any Leased Property or
Lessor's or the Agent's interest therein, Lessor, upon reasonable notice to
Hughes or such Lessee, may perform or comply with such agreement, and Lessor
shall not thereby be deemed to have waived any default caused by such failure,
and the amount of such payment and the amount of the expenses of Lessor
(including actual and reasonable attorneys' fees and expenses) incurred in
connection with such payment or the performance of or compliance with such
agreement, as the case may be, shall be deemed Supplemental Rent, payable by the
related Lessee to Lessor within ten (10) days after written demand therefor.

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

     Section XVII.1  Reports.  To the extent required under Applicable Law and
                     -------
to the extent it is reasonably practical for a Lessee to do so, such Lessee
shall prepare and file in timely fashion, or, where such filing is required to
be made by Lessor or it is otherwise not reasonably practical for a Lessee to
make such filing, Lessee shall prepare and deliver to Lessor (with a copy to the
Agent) within a reasonable time prior to the date for filing and Lessor shall
file, any material reports with respect to the condition or operation of such
Leased Property that shall be required to be filed with any Governmental
Authority.

     Section XVII.2  Binding Effect; Successors and Assigns; Survival.  The
                     ------------------------------------------------
terms and provisions of this Lease, and the respective rights and obligations
hereunder of Lessor and the Lessees, shall be binding upon their respective
successors, legal representatives and assigns (including, in the case of Lessor,

interfere in the related Lessee's or any of its permitted sublessees' quiet
enjoyment of the Leased Properties in accordance with this Lease during the
Lease Term, so long as no Event of Default has occurred and is continuing.  Such
right of quiet enjoyment is independent of, and shall not affect, Lessor's
rights otherwise to initiate legal action to enforce the obligations of the
Lessees under this Lease.

                     ------------
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 provision in any other jurisdiction, and Lessee shall remain
liable to perform its obligations hereunder except to the extent of such
unenforceability.  To the extent permitted by Applicable Law, each Lessee hereby
waives any provision of law that renders any provision hereof prohibited or
unenforceable in any respect.

     Section XVII.6  Amendment; Complete Agreements.  Neither this Lease nor any
                     ------------------------------
of the terms hereof may be terminated, amended, supplemented, waived or modified
orally, except by an instrument in writing signed by Lessor and Hughes in
accordance with the provisions of Section 8.4 of the Master Agreement. This
Lease, together with the applicable Lease Supplement and the other Operative
Documents, is intended by the parties as a final expression of their lease
agreement and as a complete and exclusive statement of the terms thereof, all
negotiations, considerations and representations between the parties having been
incorporated herein and therein. No course of prior dealings between the parties
or their officers, employees, agents or Affiliates shall be relevant or
admissible to supplement, explain, or vary any of the terms of this Lease or any
other Operative Document. Acceptance of, or acquiescence in, a course of
performance rendered under this or any prior agreement between the parties or
their Affiliates shall not be relevant or admissible to determine the meaning of
any of the terms of this Lease or any other Operative Document. No
representations, undertakings, or agreements have been made or relied upon in
the making of this Lease other than those specifically set forth in the
Operative Documents.

     Section XVII.7  Construction.  This Lease shall not be construed more
                     ------------
strictly against any one party, it being recognized that both of the parties
hereto have contributed substantially and materially to the preparation and
negotiation of this Lease.

                          --------
various Articles and Sections of this Lease are for convenience of reference
only and shall not modify, define or limit any of the terms or provisions
hereof.

         Section XVII.9   Counterparts. This Lease may be executed by the
                          ------------
parties hereto in 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.

         Section XVII.10  GOVERNING LAW. THIS LEASE SHALL IN ALL RESPECTS BE
                          -------------
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF FLORIDA
APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE,
EXCEPT AS TO MATTERS RELATING TO THE CREATION OF THE LEASEHOLD OR MORTGAGE
ESTATES HEREUNDER, AND THE EXERCISE OF RIGHTS AND REMEDIES WITH RESPECT THERETO,
WHICH SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE
STATES IN WHICH SUCH ESTATES ARE LOCATED.

         Section XVII.11  Discharge of Lessee's Obligations by its Subsidiaries
                          -----------------------------------------------------
or Affiliates. Lessor agrees that performance of any Lessee's obligations
-------------
hereunder by one or more of such Lessee's Subsidiaries or Affiliates shall
constitute performance by Lessee of such obligations to the same extent and with
the same effect hereunder as if such obligations were performed by such Lessee,
but no such performance shall excuse any Lessee from any obligation not
performed by it or on its behalf under the Operative Documents.

         Section XVII.12  Liability of Lessor Limited. Except as otherwise
                          ---------------------------
expressly provided below in this Section 17.12, it is expressly understood and
                                 -------------
agreed by and between each Lessee, Lessor and their respective successors and
assigns that nothing herein contained shall be construed as creating any
liability of Lessor or any of its Affiliates or any of their respective
officers, directors, employees or agents, individually or personally, for any
failure to perform any covenant, either express or implied, contained herein,
all such liability (other than that resulting from Lessor's gross negligence or
willful misconduct, except to the extent imputed to Lessor by virtue of any
Lessee's action or failure to act), if any, being expressly waived by each
Lessee and by each and every Person now or hereafter claiming by, through or
under any Lessee, and that, so far as Lessor or any of its Affiliates or any of
their respective officers, directors, employees or agents, individually or
personally, is concerned, each Lessee and any Person claiming by, through or
under any Lessee shall look solely to the right, title and interest of Lessor in
and to the Leased Properties and any proceeds from Lessor's sale or encumbrance
thereof (provided, however, that no Lessee shall be entitled to any double
         --------  -------
recovery) for the performance of any obligation under this Lease and under the
Operative Documents and the satisfaction of any liability arising therefrom
(other than that resulting from Lessor's gross negligence or willful misconduct,
except to the extent imputed to Lessor by virtue of any Lessee's action or
failure to act).

                          ---------------------
at any time and from time to time during the Lease Term, it will promptly, but
in no event later than thirty (30) days after request by the other party hereto,
execute, acknowledge and deliver to such other party or to any prospective
purchaser (if such prospective purchaser has signed a commitment or letter of
intent to purchase any Leased Property or any part thereof or any Note),
assignee or mortgagee or third party designated by such other party, a
certificate stating (a) that this Lease is unmodified and in force and effect
(or if there have been modifications, that this Lease is in force and effect as
modified, and identifying the modification agreements); (b) the date to which
Basic Rent has been paid; (c) whether or not there is any existing default by
any Lessee in the payment of Basic Rent or any other sum of money hereunder, and
whether or not there is any other existing default by either party with respect
to which a notice of default has been served, and, if there is any such default,
specifying the nature and extent thereof; (d) whether or not, to the knowledge
of the signer, there are any setoffs, defenses or counterclaims against
enforcement of the obligations to be performed hereunder existing in favor of
the party executing such certificate and (e) other items that may be reasonably
requested; provided that no such certificate may be requested unless the
           --------
requesting party has a good faith reason for such request.

         Section XVII.14  No Joint Venture. Any intention to create a joint
                          ----------------
venture, partnership or other fiduciary relationship between Lessor and any
Lessee is hereby expressly disclaimed.

         Section XVII.15  No Accord and Satisfaction. The acceptance by Lessor
                          --------------------------
of any sums from any Lessee (whether as Basic Rent or otherwise) in amounts
which are less than the amounts due and payable by the Lessees hereunder is not
intended, nor shall be construed, to constitute an accord and satisfaction of
any dispute between Lessor and any Lessee regarding sums due and payable by any
Lessee hereunder, unless Lessor specifically deems it as such in writing.

         Section XVII.16  No Merger. In no event shall the leasehold interests,
                          ---------
estates or rights of any Lessee hereunder, or of the holder of any Notes secured
by a security interest in this Lease, merge with any interests, estates or
rights of Lessor in or to the Leased Properties, it being understood that such
leasehold interests, estates and rights of each Lessee hereunder, and of the
holder of any Notes secured by a security interest in this Lease, shall be
deemed to be separate and distinct from Lessor's interests, estates and rights
in or to the Leased Properties, notwithstanding that any such interests, estates
or rights shall at any time or times be held by or vested in the same person,
corporation or other entity.

         Section XVII.17  Survival. The obligations of the parties to be
                          --------

<PAGE>

applicable statute of limitations by Lessor, any Lessee, the Agent or any
Indemnitee shall not affect such survival.

         Section XVII.18  Chattel Paper. To the extent that this Lease
                          -------------
constitutes chattel paper (as such term is defined in the Uniform Commercial
Code in any applicable jurisdiction), no security interest in this Lease may be
created through the transfer or possession of any counterpart other than the
sole original counterpart, which shall be identified as the original counterpart
by the receipt of the Agent.

VIII, X or XIV or this Section 17.21 shall be held by the Agent (or Lessor if
----  -    ---         -------------
the Loans have been fully paid) as security for the obligations of the Lessees
under this Lease and the Master Agreement and of Lessor under the Loan
Agreement. At such time as such amounts are payable to the Lessee, such amounts,
net of any amounts previously applied to the Lessees' obligations hereunder or
under the Master Agreement (which application is hereby agreed to by Lessee),
shall be paid to the related Lessee. Any such amounts which are held by the
Agent (or Lessor if the Loans have been fully paid) pending payment to a Lessee
shall until paid to such Lessee, as provided hereunder or until applied against
the Lessees' obligations herein and under the Master Agreement and distributed
as provided in the Loan Agreement or herein (after the Loan Agreement is no
longer in effect) in connection with any exercise of remedies hereunder, be
invested by the Agent or Lessor, as the case may be, as directed from time to
time in writing by Lessee (provided, however, if an Event of Default has
                           --------  -------
occurred and is continuing it will be directed by the Agent or, if the Loans
have been fully paid, Lessor) and at the expense and risk of the Lessees, in
Permitted Investments. Any gain (including interest received) realized as the
result of any such investment (net of any fees, commissions and other expenses,
if any, incurred in connection with such investment) shall be applied in the
same manner as the principal invested. Lessee upon demand shall pay to the Agent
or Lessor, as appropriate, the amount of any loss incurred in connection with
all such investments and the liquidation thereof.

         Section XVII.22  Ground Leases. Each Lessee will, at its expense,
                          -------------
timely perform all of the obligations of Lessor, in its capacity as ground
lessee, under each Ground Lease and, if requested by Lessor, shall provide

to any Leased Property exceeds 25% of the projected Leased Property Balance for
such Leased Property as set forth in the Construction Budget for such Leased
Property, the Raw Land and the Building related to such Leased Property shall be
leased under separate Lease Supplements. If any Building and the Raw Land on
which such Building is located are subject to separate Lease Supplements, at any
time that the related Lessee exercises an option to purchase such Building or
such Raw Land, or to renew this Lease with respect to such Building or such Raw
Land, or purchases such Building or such Land as a result of an Event of Loss,
an Event of Taking or an Event of Default, such purchase or renewal shall be
made simultaneously with respect to all of such Building and such Raw Land.

         Section XVII.24  Joint and Several. Each obligation of each Lessee
                          -----------------

         Section XVII.25  IDB Documentation. If any Leased Property is subject
                          -----------------
to an IDB Lease, this Lease shall be deemed to be a sublease. Each Lessee hereby
agrees to perform all of its obligations and all obligations of Lessor under all
IDB Documentation related to any Leased Property. In the event that a Lessee
purchases any Leased Property that is the subject of IDB Documentation, such
Lessee shall prepay, or cause to be prepaid, the Bonds related to such Leased
Property or shall assume all obligations of the Lessor related to such IDB
Documentation and cause the Lessor to be released therefrom pursuant to
documentation reasonably satisfactory to the Lessor.
