made and entered into among CPSIEM, LLC, a Delaware limited liability company,

having an address at c/o CE Richard Ellis Investors, L.L.C., 865 S. Figueroa

1.1      Lease of Premises; Title and Condition.

         (a) In consideration of the rents and covenants herein stipulated to be
paid and performed by Tenant and upon the terms and conditions herein specified,
Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the
premises (the "Premises") consisting of:

                  (i) that certain parcel of land more particularly described on
Schedule A attached hereto and made a part hereof, together with all of the
Landlord's right, title and interest, if any, in and to (1) all easements,
rights-of-way, appurtenances, and other rights and benefits belonging to the
parcel of land, and (2) all public or private streets, roads, avenues, alleys,
or passageways, open or proposed, on or abutting each of the parcels of land,
and any award made or to be made in lieu thereof (collectively, the "Land ");
and

                  (ii) all buildings located on the Land, together with all
plumbing, electrical, ventilating, heating, cooling, lighting and other utility
systems, equipment, ducts and pipes attached to or comprising a part thereof
(the "Improvements"); and

                  (iii) all machinery and equipment owned by Landlord and
located on, attached, affixed or incorporated into the Land and Improvements
including, without limitation, all floor coverings, lighting, appliances,
telephone wiring and jacks, and other miscellaneous fixtures and equipment now
or hereafter located on the Land and used in the operation of the Improvements
(the "Equipment").

Notwithstanding anything to the contrary in the foregoing, the Premises and the
Equipment do not include Tenant's personal property, Tenant's or any sublessee's
tradenames or trademarks or the right to use the same (collectively, the
"Tenant's Personal Property "), which shall remain the property of Tenant, or
its affiliates, as the case may be.

The Premises are leased to TENANT in their present condition without
representation or warranty by Landlord and subject to the rights of parties in
possession, to the existing state of title and any state of facts which an

                                       1

<PAGE>

accurate survey or physical inspection might reveal, to all applicable Legal
Requirements (as hereinafter defined) now or hereafter in effect and subject to
those matters listed in Schedule B attached hereto and made a part hereof (the
"Permitted Exceptions").

         (b) Tenant has examined the Premises and title to the Premises and has
found all of the same satisfactory for all purposes. Tenant acknowledges that
Tenant is fully familiar with the physical condition of the Premises and that
the Landlord makes no representation or warranty, express or implied, with
respect to same. THE LEASE OF THE PREMISES IS ON AN " AS IS" BASIS, IT BEING
AGREED THAT TENANT WILL LEASE THE PREMISES IN THEIR PRESENT CONDITION, WITH ALL
FAULTS. LANDLORD HEREBY DISCLAIMS ANY AND ALL EXPRESS OR IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE RELATIVE TO THE PREMISES
OR ANY COMPONENT PART THEREOF. Tenant acknowledges and agrees that no

or toxic substances), (ii) the condition or repair of the Premises or any
portion thereof, (iii) the value, expense of operation or income potential of
the Premises, (iv) the accuracy or completeness of any title, survey, structural
reports, environmental audits or other information provided to Tenant by any
third party contractor relative to the Premises (regardless of whether the same
were retained or paid for by Landlord), or (v) any other fact or condition which
has or might affect the Premises or the condition, repair, value, expense of
operation or income potential thereof. Tenant represents that the officers of
Tenant are knowledgeable and experienced in the leasing of properties comparable
to the Premises and agrees that Tenant will be relying solely on Tenant's
inspections of the Premises in leasing the Premises. THE PROVISIONS OF THIS
PARAGRAPH HAVE BEEN NEGOTIATED AND ARE INTENDED TO BE A COMPLETE EXCLUSION AND
NEGATION BY THE LANDLORD OF, AND THE LANDLORD DOES HEREBY DISCLAIM, ANY AND ALL
WARRANTIES BY THE LANDLORD, EXPRESS OR IMPLIED, WITH RESPECT TO THE PREMISES OR
ANY PORTION THEREOF, WHETHER ARISING PURSUANT TO THE UNIFORM COMMERCIAL CODE OR
ANY OTHER LAW NOW OR HEREAFTER IN EFFECT OR OTHERWISE, AND TENANT HEREBY
ACKNOWLEDGES AND ACCEPTS SUCH EXCLUSION, NEGATION AND DISCLAIMER.

defined in Section 2.2 (b) hereof) and other recorded covenants, restrictions or
agreements which are applicable to the Premises. Tenant shall not use, occupy or
permit the premises to be used or occupied, nor do or permit anything to be done
in or on the premises in a manner which would (i) violate any certificate of
occupancy or equivalent certificate affecting the Premises or violate any zoning
or other law, ordinance or regulation, (ii) make void or voidable any insurance
then in

                                       2

effect with respect to the Premises, (iii) materially and adversely affect in

Improvements which is not repaired in accordance with the provisions of this
Lease, (v) violate any provision of an applicable ground lease, or (vi)

any or all appropriate governmental authorities have been obtained by Tenant, at
Tenant's sole cost and expense, and are in full force and effect.

1.3 Terms.

         The Premises are leased for a primary term (the "Primary Term")
covering the period shown on Schedule C attached hereto to the right of the
words "Primary Term", and, at Tenant's option, for up to five (5) five year
consecutive additional terms (the "Extended Terms"), unless and until the term
of this Lease shall expire or be terminated pursuant to any provision hereof.
The Primary Term and each Extended Term (collectively, the "Term") shall
commence and expire on the dates set forth in Schedule C attached hereto and
made a part hereof. "Commencement Date" shall refer to the commencement date of
the Primary Term.

So long as no Event of Default shall have occurred and be continuing, Tenant may
elect to exercise its option to extend the term of this Lease for an Extended
Term by giving written notice thereof to Landlord not later than (i) 365 days
prior to the expiration of the Primary Term, with respect to the first Extended
Term, and (ii) 365 days prior to the expiration of the then current Term, with
respect to any other Term. If Landlord and Tenant cannot agree in writing on the
Fair Market Rent of the Premises, Tenant's notice of election to extend the term
of this Lease for the first Extended Term shall be accompanied by an appraisal
of the then Fair Market Rent of the Premises prepared by an Appraiser.
"Appraiser" shall mean a member of the Appraisal Institute, in good standing,
holding the MAI designation and who is licensed in the State of Nevada (or
associated with a nationally recognized firm if permitted under applicable law)
and who is familiar with the Nevada market and single-tenant properties with
comparable or similar uses. Subject to Tenant's right to rescind its notice to
extend the Term as provided in Section 1.4(a) hereof, such notice shall
automatically extend the term of this Lease for the Extended Term selected,
without further writing; provided, however, either party, upon request of the
other, shall execute and acknowledge, in form suitable for recording, an
instrument confirming any such extension. Each Extended Term shall be upon the
same terms as provided in this Lease for the Primary Term, except as otherwise
stated herein. Tenant shall not be entitled to extend the term of this Lease for
any Extended Term unless Tenant shall have extended the term of this Lease for
the preceding Extended Term, if any.

1.4 Rent.

                                       3

<PAGE>

         (a) Tenant shall pay to Landlord (or to such other party as Landlord
may from time to time specify in writing at least ten days before Tenant makes
payment) by federal funds wire transfer in immediately available funds (in U.S.
Dollars) (or, if the original Landlord has sold the Premises or there has been a
sale of the ownership interest in the original Landlord, by company check) as
basic rent for the Premises during the Primary Term the amounts set forth in
Schedule D attached hereto and made a part hereof (the "Basic Rent") on the
dates set forth therein (or if any such date falls on a day which is not a
Business Day (defined as any day other than a Saturday or Sunday or other day on
which the banks in New York, New York are authorized or required to be closed),
the next succeeding Business Day, the "Payment Dates"), to such account as
Landlord from time to time may designate.

         Tenant shall pay Basic Rent for the Extended Terms, if any, in the same
manner as required for the Primary Term, monthly in advance beginning on the
15th day of the first month of the First Extended Term and on the 15th day of
each month thereafter for the remainder of the Term. The Basic Rent for each
month of the first year of the first Extended Term shall be equal to the greater
of (i) 101.5% of the Basic Rent for the last month of the Primary Term and (ii)
the Fair Market Rent for the Premises as of the commencement of the first
Extended Term. The annual Basic Rent for the second year of the first Extended
Term and for each year thereafter for the remainder of the Term shall be
increased by 1.5% annually, but 1/12 of such annual Basic Rent shall be payable
each month in advance.

         The term "Fair Market Rent" shall mean the rental value of the Premises
under the terms and conditions of this Lease and determined at the time in
question. If Landlord and Tenant agree upon the Fair Market Rent of the Premises
at the time the notice to extend is given, the Fair Market Rent shall be as
agreed. If Landlord is in agreement with the appraisal delivered by Tenant
pursuant to Section 1.3 above, such appraisal, if any, shall determine the Fair
Market Rent. If Landlord gives Tenant written notice of its disapproval (the
"Disapproval Notice") of Tenant's appraisal (to be delivered by Landlord within
30 days after Landlord's receipt of Tenant's appraisal) Fair Market Rent shall
be determined in accordance with the following procedure:

         Within thirty days after the delivery of the Disapproval Notice,
Landlord shall submit to Tenant an appraisal of Fair Market Rent of the
Premises, prepared by an Appraiser. If the higher of the two appraised values
determined by the Appraisers for Landlord and Tenant is less than or equal to
105% of the lower appraised value, then Fair Market Rent shall be set at the
average of the two appraised values. If the two appraised values differ by more
than five percent, then Landlord's appraiser and Tenant's appraiser shall
jointly, within thirty days after delivery of the Disapproval Notice, choose a
third Appraiser who shall, within fifteen days after receipt of both Landlord's
and Tenant's appraisals, choose one of the two appraised values as the Fair
market rent. the fair market rent, as determined by the foregoing arbitration
procedure, shall be binding upon both Tenant and Landlord. if fair market rent
determined in accordance with the procedure set forth in this paragraph exceeds
105% of the Fair Market Rent given by the Tenant's

                                       4

<PAGE>

Appraiser, the Tenant shall have the right to rescind its notice to extend the
term of this Lease within 15 days after such determination of Fair Market Rent
by giving Landlord written notice of such rescission. Whether or not Tenant
rescinds its notice to extend the term of this Lease, the fees and expenses of
the Appraisers shall be borne by Tenant.

         (b) All taxes, costs, expenses and amounts which Tenant is required to
pay pursuant to this Lease (other than Basic Rent), together with every fine,
penalty, interest and cost which may be added for non-payment or late payment
thereof, shall constitute additional rent ("Additional Rent"). If Tenant shall
fail to pay any such Additional Rent or any other sum due hereunder when the
same shall become due, Landlord shall have all rights, powers and remedies with
respect thereto as are provided herein or by law in the case of non-payment of
any Basic Rent and shall, except as expressly provided herein, have the right to
pay the same on behalf of Tenant. Tenant shall pay to Landlord interest, at a
rate (the "Default Rate") equal to the lesser of fifteen percent per annum and
the maximum rate permitted by law, on all overdue Basic Rent from the due date
thereof until paid and on all overdue Additional Rent and all other sums due
hereunder, from the end of the third Business Day after delivery of written
notice of default to Tenant. In addition, if Tenant fails to make any payment of
Basic Rent, Additional Rent or other sums payable hereunder to Landlord within
three Business Days after delivery of written notice to Tenant that any such
Basic Rent, Additional Rent, or other sum payable hereunder has not been paid on
the due date thereof, Tenant shall pay a late charge equal to four percent (4%)
of the amount past due. Tenant shall perform all its obligations under this
Lease at its sole cost and expense, and shall pay all Basic Rent, Additional
Rent and any other sum due hereunder when due and payable, without offset,
notice or demand.

                                   ARTICLE 2.

2.1      Net Lease.

         (a) This Lease is a net lease and, any present or future law to the
contrary notwithstanding, shall not terminate except as otherwise expressly
provided herein, nor shall Tenant be entitled to any abatement, reduction,
diminution, set-off, counterclaim, defense (except for the defense that the
performance or payment has been made) or deduction with respect to any Basic
Rent, Additional Rent or other sums payable hereunder, nor shall Tenant be
excused from the performance of its obligations hereunder, by reason of: any
damage to or destruction of the Premises or any portion thereof; any defect in
the condition, design, operation or fitness for use of the Premises or any
portion thereof; any taking of the Premises or any part thereof by condemnation
or otherwise; any prohibition, limitation, interruption, cessation, restriction
or prevention of tenant's use, occupancy or enjoyment of the premises, or any
interference with such use, occupancy or enjoyment by any person; any eviction
by paramount title or otherwise; any default by Landlord hereunder or under any
other agreement; the impossibility or

                                        5

<PAGE>

illegality of performance by Landlord, Tenant or both; any action of any
governmental authority (including, without limitation, changes in Legal
Requirements); construction on or renovation of the Premises; or any failure in
the Premises to comply with applicable laws, Legal Requirements, or any other
cause whether similar or dissimilar to the foregoing. All costs, expenses and
obligations of every kind and nature whatsoever relating to the Premises and the
appurtenances thereto and the use and occupancy thereof which may arise or
become due and payable with respect to the period which ends on the expiration
or earlier termination of the Term in accordance with the provisions hereof
(whether or not the same shall become payable during the Term or thereafter)
shall be paid by Tenant. It is the purpose and intention of the parties to this
Lease that the Basic Rent, Additional Rent and other sums payable to Landlord
hereunder shall be absolutely net to Landlord and that this Lease shall yield,
net to Landlord, the Basic Rent, Additional Rent, and other sums payable to
Landlord as provided in this Lease. The parties intend that the obligations of
Tenant hereunder shall be separate and independent covenants and agreements and
shall continue unaffected unless such obligations shall have been modified or
terminated pursuant to an express provision of this Lease.

         (b) Tenant shall remain obligated under this Lease in accordance with
its terms and shall not take any action to terminate, rescind or avoid this
Lease, notwithstanding any bankruptcy, insolvency, reorganization, liquidation,
dissolution or other proceeding affecting Landlord or any action with respect to
this Lease which may be taken by any trustee, receiver or liquidator or by any
court.

         (c) Tenant waives all rights to surrender this Lease, or to any
abatement or deferment of Basic Rent, Additional Rent or other sums payable
hereunder. Tenant waives all rights to terminate this Lease, except in the case
of a Total Condemnation, Major Condemnation or Major Casualty in accordance with
the provisions of Article 3.

2.2      Taxes and Assessments; Compliance with Law.

         (a) Subject to Tenant's right to contest pursuant to Section 2.6 of
this Lease, Tenant shall pay, prior to delinquency, all "Impositions", which are
defined as: (i) all taxes (including, without limitation, those described in
(iii) below), assessments (including, without limitation, all assessments for
public improvements or benefits, whether or not commenced or completed prior to
the date hereof and whether or not commenced or completed within the term of
this Lease), excises, levies, fees (including, without limitation, license,
permit, inspection, authorization and similar fees), water and sewer rents and
charges, and all other governmental charges, general and special, ordinary and
extraordinary, foreseen and unforeseen, and any interest and penalties thereon
which are, at any time prior to or during the Primary Term or any Extended Term
hereof, imposed or levied upon or assessed against or which arise with respect
to (A) the Premises, (B) any Basic Rent, Additional Rent or other sums payable
hereunder, (C) this Lease or the leasehold estate hereby created or (D) the
operation, possession or use of the Premises; (ii) all gross receipts or similar
taxes (i.e., taxes based upon gross income

                                       6

<PAGE>
which fail to take into account deductions with respect to depreciation,
interest, taxes or ordinary and necessary business expenses, in each case
relating to the Premises) imposed or levied upon, assessed against or measured
by any Basic Rent, Additional Rent or other sums payable hereunder; (iii) all
sales (including those imposed on lease rentals), value added, ad valorem, gross
receipts, use and similar taxes at any time levied, assessed or payable on
account of the acquisition, ownership, leasing, operation, possession or use of
the Premises; (iv) all transfer, recording, stamp and real property gain taxes
incurred upon the sale or transfer, or other disposition of the Premises or any
interest therein to Tenant or the foreclosure of the Premises, (v) all offers,
claims and demands of mechanics, laborers, materialmen and others which, if
unpaid, might create a lien on the Premises, (vi) all charges of utilities,
communications and similar services serving the Premises, and (vii) any other
tax relating to the Premises resulting from any law enacted or adopted or
amended after the date of this Lease imposed on Landlord pursuant to any deed of
trust or mortgage creating a first mortgage lien on the Premises ("Indenture").
Notwithstanding the above, Tenant shall not be required to pay any franchise,
estate, inheritance, transfer, net income or similar tax of Landlord (other than
any tax referred to in clause (ii) above) unless such tax is imposed, levied or
assessed in substitution for any other tax, assessment, charge or levy which
Tenant is required to pay pursuant to this Section 2.2 (a). Subject to Tenant's
right to contest pursuant to Section 2.6 of this Lease, Tenant will furnish to
Landlord, within 30 days after the due date thereof, proof of payment of all
Impositions. If any such Imposition may legally be paid in installments, Tenant
may pay such Imposition in installments; in such event, Tenant shall be liable
only for installments which become due and payable during the Term hereof.

      (b)   Tenant shall comply with and cause the Premises to comply with and
shall assume all obligations and liabilities with respect to (i) all laws,
ordinances and regulations, and other governmental rules, orders and
determinations presently in effect or hereafter enacted, made or issued, both
foreseen and unforeseen and ordinary and extraordinary applicable to the
Premises or the ownership, operation, use or possession thereof and (ii) all
contracts (including, but not limited to, insurance policies (including, without
limitation, to the extent necessary to prevent cancellation thereof and to
insure full payment of any claims made under such policies)), covenants,
conditions and restrictions now or hereafter applicable to the Premises or the
ownership, operation, use or possession thereof (collectively, "Legal
Requirements"), including but not limited to all such Legal Requirements,
contracts, agreements, covenants, conditions and restrictions which require
structural, unforeseen or extraordinary changes. Notwithstanding the foregoing,
Legal Requirements shall not include any contracts, covenants, conditions or
restrictions applicable to the Premises which are hereafter voluntarily entered
into by Landlord without the consent or approval of Tenant (which approval shall
not be unreasonably withheld or delayed), unless Landlord is required to enter
into such contract, covenant, condition or restriction by any governmental or
quasi-governmental entity. Tenant's failure to comply with any such contract,
covenant, condition or restriction required by any governmental or
quasi-governmental entity to be

                                        7
<PAGE>
entered into by Landlord shall not constitute a default by Tenant hereunder
prior to Tenant's receipt of notice or knowledge thereof.

2.3   Liens. Subject to Tenant's right to contest pursuant to Section 2.6 of
this Lease, Tenant will act promptly to remove and discharge any charge, lien,
security interest or encumbrance upon the Premises or any Basic Rent, Additional
Rent or other sums payable hereunder which arise for any reason, including all
liens which arise out of the possession, use, occupancy, construction, repair or
rebuilding of the Premises or by reason of labor or materials furnished or
claimed to have been furnished to Tenant or for the Premises, but not including
(i) the Permitted Exceptions, and (ii) any mortgage, charge, lien, security
interest or encumbrance created by Landlord without the consent of Tenant (it
being agreed that an Indenture for purposes of this sentence will be deemed to
have been created without the consent of Tenant). Nothing contained in this
Lease shall be construed as constituting the consent or request of Landlord,
express or implied, to or for the performance by any contractor, laborer,
materialman, or vendor of any labor or services or for the furnishing of any
materials for any construction, alteration, addition, repair or demolition of or
to the Premises or any part thereof which would result in any liability of the
Landlord for the payment therefor. Notice is hereby given that Landlord will not
be liable for any labor, services or materials furnished or to be furnished to
Tenant, or to anyone holding an interest in the Premises or any part thereof
through or under Tenant, and that no mechanic's or other liens for any such
labor, services or materials shall attach to or affect the interest of Landlord
in the Premises.

2.4   Indemnification.

      (a)   Tenant agrees to defend, indemnify, and hold harmless Landlord and
Lender from and against any and all liabilities, losses, damages, penalties,
expenses (including reasonable attorneys' fees and expenses), causes of action,
suits, claims, demands or judgments of any nature whatsoever, howsoever caused,
arising from the Premises and the use, occupancy, condition, design,
construction, maintenance, repair or rebuilding of the Premises, and any injury
to or death of any person or persons or any loss of or damage to any property,
real or personal, in any manner arising therefrom or occurring thereon, whether
or not Landlord or Lender has or should have knowledge or notice of the defect
or conditions, if any, causing or contributing to said injury, death, loss,
damage or other claim; but with respect to Landlord (and not as to Lender)
except to the extent that any such liability, loss, damage, penalty, expense,
cause of action, suit, claim, demand or judgment is the result of the gross
negligence of Landlord or the intentional wrongful act of Landlord. In case any
action or proceeding is brought against Landlord or the mortgagee or beneficiary
under an Indenture ("Lender") by reason of any such claim against which Tenant
has agreed to defend, indemnify, and hold harmless pursuant to the preceding
sentence, Tenant covenants upon notice from Landlord or Lender to defend
Landlord and Lender in such action, with the expenses of such defense paid by
Tenant, and Landlord will cooperate and assist in the defense of such action or
proceeding if reasonably requested by Tenant.

                                        8
<PAGE>
      (b)   The obligations of Tenant under this section 2.4 shall survive the
expiration or earlier termination of this Lease.

2.5   Maintenance and Repair.

      (a)   Tenant acknowledges that it has received the Premises in good order
and repair. Tenant, at its own expense, will maintain all parts of the Premises
(including all parking areas) in good repair and condition and will take all
action and will make all structural and non-structural, foreseen and unforeseen
and ordinary and extraordinary changes and repairs which may be required to keep
all parts of the Premises in good repair and condition. Landlord shall not be
required to maintain, repair or rebuild all or any part of the Premises. Tenant
waives the right to (i) require Landlord to maintain, repair or rebuild all or
any part of the Premises, or (ii) make repairs at the expense of Landlord
pursuant to any Legal Requirement, contract, covenant, condition or restriction
set forth in subsection 2.2(b)(ii), at any time in effect.

      (b)   If all or any part of the Improvements shall encroach upon any
property, street or right-of-way adjoining or adjacent to the Premises, or shall
violate the agreements or conditions affecting the Premises, or any Legal
Requirements, or shall hinder, obstruct or impair any easement or right-of-way
to which the Premises are subject, then, promptly after written request of
Landlord (unless such encroachment, violation, hindrance, obstruction or
impairment is a Permitted Exception) or of any person so affected, Tenant shall,
at its expense, either (i) obtain valid and effective waivers or settlements of
all claims, liabilities and damages resulting therefrom, or (ii) make such
changes, including alteration or removal, to the Improvements and take such
other action as shall be necessary to remove or eliminate such encroachments,
violations, hindrances, obstructions or impairments, provided that, if
Landlord's consent is required for such changes pursuant to this Lease,
Landlord's consent shall have been obtained, which consent shall not be
unreasonably withheld.

2.6   Permitted Contests.

      (a)   After prior written notice to Landlord and Lender, Tenant shall not
be required to (i) pay any Imposition, (ii) comply with any Legal Requirement,
or (iii) discharge or remove any lien or encumbrance so long as Tenant shall
contest, in good faith and at its expense, the existence, the amount or the
validity thereof, the amount of the damages caused thereby, or the extent of its
or Landlord's liability therefor, by appropriate proceedings which shall operate
during the pendency thereof to prevent (A) the collection of, or other
realization upon, the Imposition or lien so contested, (B) the sale, forfeiture
or loss of any of the Premises, any Basic Rent, or any Additional Rent to
satisfy the same or to pay any damages caused by the violation of any Legal
Requirement or by any such violation, (C) any interference with the use or
occupancy of any of the premises, (D) any interference with the payment of any
Basic Rent or any Additional Rent, (E) the cancellation of any fire or other
insurance policy.

                                       9
<PAGE>
      (b)   In no event shall Tenant pursue any contest with respect to any
Imposition, Legal Requirement, lien or violation, referred to above in such
manner that exposes Landlord or Lender to (i) criminal liability, penalty or
sanction, (ii) any civil liability, penalty or sanction for which Tenant has not
made provisions reasonably acceptable to Landlord and Lender or (iii) defeasance
of its interest in the Premises.

      (c)   Tenant agrees that each contest shall be promptly and diligently
prosecuted to a final conclusion, except that Tenant shall have the right to
attempt to settle or compromise such contest through negotiations. Tenant shall
pay, indemnify, defend and save Lender and Landlord harmless against any and all
losses, judgments, decrees and costs (including all attorneys' fees and
expenses) in connection with any such contest and shall, promptly after the
final determination of such contest, fully pay and discharge the amounts which
shall be levied, assessed, charged or imposed therein, together with all
penalties, fines, interest and expenses thereof, and perform all acts the
performance of which shall be ordered as a result thereof. The obligations of
Tenant under this Section 2.6(c) shall survive the expiration or earlier
termination of this Lease.

                                   ARTICLE 3.

3.1   Omitted

3.2   Condemnation and Casualty.

      (a)   General Provisions. Subject to Tenant's rights to utilize or obtain
the same in accordance with Section 3.5, Tenant hereby irrevocably assigns to
Landlord any award, compensation or insurance payment to which Tenant may become
entitled by reason of Tenant's interest in the Premises (i) if the use,
occupancy or title of the Premises or any part thereof is taken, requisitioned
or sold in, by or on account of any actual or threatened eminent domain
proceeding or other action by any person having the power of eminent domain
("Condemnation") or (ii) if the Premises or any part thereof is damaged or
destroyed by fire, flood or other casualty ("Casualty") (all awards,
compensations, and insurance payments on account of any Condemnation or Casualty
(net of any amounts applicable to Tenant's Personal Property) are hereinafter
collectively called "Compensation"). In the event of any Casualty, or in the
event of a Condemnation or threatened Condemnation, Tenant shall give prompt
written notice thereof to Landlord (which notice shall set forth Tenant's good
faith estimates of the cost of repairing or restoring any damage or destruction
caused thereby, or, if Tenant cannot reasonably estimate the anticipated cost of
restoration, Tenant shall nonetheless give Landlord prompt notice of the
occurrence of any such Casualty or Condemnation, and will diligently proceed to
obtain estimates to enable Tenant to quantify the anticipated cost of such
restoration, whereupon Tenant shall promptly notify Landlord of such good faith
estimate). Landlord and Lender may participate in any such proceeding or action
to negotiate, prosecute and adjust any claim for any Compensation, and Landlord
(or if

                                       10
<PAGE>
required by an Indenture, Lender) shall collect any such Compensation. Tenant
shall pay all reasonable costs and expenses of Tenant, Landlord and Lender in
connection with each such proceeding, action, negotiation, prosecution and
adjustment. If an Event of Default shall have occurred and be continuing or in
the case of any Condemnation or Major Casualty where Tenant is not purchasing
the Premises pursuant to Section 3.2, Landlord shall have the sole right to
conduct and control such proceedings, actions, negotiations, prosecutions and
adjustments; otherwise, Tenant shall initiate, conduct and control any such
proceeding, action, negotiation, prosecution or adjustment. All Compensation
shall be applied pursuant to the applicable provisions of Article 3, and all
such Compensation (less the reasonable costs and expenses of Landlord, Tenant
and Lender, if applicable, in collecting such Compensation), is herein called
the "Net Proceeds".

      (b)   Total Condemnation. Subject to the provisions of Section 3.2(f)
below, if a Condemnation consists of a total taking of the Premises ("Total
Condemnation"), then this Lease shall terminate on the first Payment Date (the
"Lease Termination Date") which occurs not less than 120 days and not more than
150 days after receipt of the notice of such condemnation from Tenant pursuant
to Section 3.2(a).

      (c)   Major Condemnation and Major Casualty. If a Condemnation is not a
Total Condemnation but it renders the Premises unsuitable for restoration for
continued use and occupancy in Tenant's business (a "Major Condemnation"), or if
a Casualty shall occur and the Restoration Cost shall exceed 50% of the
Stipulated Loss Value ("Major Casualty"), then Tenant may terminate this Lease
on the Lease Termination Date (defined below) by delivering to Landlord and if
required by an Indenture, Lender, in both cases, not later than thirty days
after such Major Condemnation or Major Casualty: (i) notice of its intention to
terminate this Lease on the first Payment Date (the "Lease Termination Date")
which occurs not less than 120 days and not more than 150 days after the
delivery of such notice (it being understood that in all events under this
Lease, the Lease Termination Date must be on a Payment Date) and (ii) a
certificate of Tenant stating that Tenant has determined in good faith in the
case of a Major Casualty, that the Restoration Cost exceeds 50% of the
Stipulated Loss Value, or in the case of a Major Condemnation that such Major
Condemnation has rendered the Premises unsuitable for restoration for continued
use and occupancy in Tenant's business, and (iii) documentation to the effect
that termination of this Lease will not be in violation of any agreement then in
effect with which Tenant is obligated to comply pursuant to this Lease. If the
Lease Termination Date occurs during the Primary Term, such notice must be
accompanied by a Rejectable Purchase Offer, as described in Section 3.2(e), in
which event the provisions of such Section shall be controlling. If Tenant does
not give notice of termination in accordance with this Section 3.2(c), then the
Lease shall remain in full force and effect and there shall be no reduction or
abatement of rent despite the Major Condemnation or Major Casualty.

      (d)   Payments; Adjustment to Basic Rent. If this Lease terminates due to
a Total Condemnation, a Major Condemnation, or a Major

                                       11
<PAGE>
Casualty under Sections 3.2(b) or (c), then: (i) any Net Proceeds (other than
those specifically relating to the Tenant's Personal Property) payable in
connection with the Total Condemnation, Major Condemnation, or a Major Casualty
(or the right to receive the same when made if payment therefor has not yet been
made) shall be assigned or paid and belong to the Landlord or if required by an
Indenture, Lender (unless the Premises are being transferred to the Tenant
pursuant to Section 3.2(f) (purchase) in which case the Net Proceeds shall be
assigned or paid to Tenant), (ii) the Tenant shall pay to the Landlord all Basic
Rent accrued as of such Lease Termination Date and all other amounts then
accrued or due and payable by the Tenant under this Lease and (iii) if an Event
of Default has occurred and is continuing, Tenant shall pay to Landlord any Make
Whole Premium. The "Make Whole Premium" shall have the meaning set forth in an
Indenture, or if not defined in an Indenture, shall mean the amount which
Landlord is obligated to pay in excess of outstanding principal and accrued
interest in connection with a prepayment or defeasance of an Indenture.

      (e)   Rejectable Purchase Offer. If during the Primary Term, there is a
Major Condemnation or a Major Casualty for which Tenant gives timely notice of
termination under Section 3.2(c) or a Total Condemnation, Tenant shall deliver
to Landlord (in addition to the items set forth in Section 3.2(a) and (c)
above), no later than thirty (30) days after such Total or Major Condemnation or
Major Casualty, an appraisal of the Premises in accordance with Schedule F and a
written offer ("Rejectable Purchase Offer") to purchase Landlord's interest in
the Premises on the Lease Termination Date for a price equal to the greater of
(i) the then Fair Market Value of the Premises (determined in accordance with
Schedule F) and (ii) the amount ("Stipulated Loss Value") set forth on Schedule
E. Within 90 days of the date Landlord receives the Rejectable Purchase Offer,
Landlord shall deliver written notice of its election to either accept or reject
Tenant's Rejectable Purchase Offer (with a failure to respond constituting an
acceptance of such Rejectable Purchase Offer). Any rejection by Landlord of a
Rejectable Purchase Offer shall comply with and be accomplished in accordance
with the provisions of Section 3.4.

      (f)   Acceptance of Rejectable Purchase Offer. In the event of an
acceptance or deemed acceptance of a Rejectable Purchase Offer, on the
applicable Lease Termination Date, (i) Tenant shall, by wire transfer of
immediately available funds, pay to Landlord the applicable price, together with
all Basic Rent, Additional Rent and other sums accrued or due and payable under
this Lease as of the applicable Lease Termination Date and, if an Event of
Default has occurred and is continuing, the Make Whole Premium (ii) the Net
Proceeds with respect to the Premises shall be assigned or turned over to the
Tenant upon Tenant's payment of the amounts set forth in this subsection (or if
any Net Proceeds have been applied to a Loan, such amount shall be credited
against Tenant's payment obligation under this subsection) and (iii) Landlord
shall convey to Tenant fee simple title in the Premises (to the extent any
portion has not been condemned) subject only to the Permitted Exceptions (which
shall not include any mortgage created by Landlord) and any other liens,
charges, restrictions or encumbrances created by Tenant or any of its creditors,
employees, contractors, or agents or

                                       12
<PAGE>
created by Landlord pursuant to the express terms hereof or with Tenant's
consent. Tenant shall pay (i) all charges incident to such conveyance,
including, without limitation, reasonable counsel fees, escrow fees, recording
fees, title insurance premiums, transfer taxes and all other applicable taxes
(other than any income or franchise taxes of Landlord) which may be imposed by
reason of such conveyance and the delivery of said deed or conveyance and other
instruments and (ii) all costs and expenses incurred by Landlord in connection
with a prepayment of all or any portion of the indebtedness secured by an
Indenture, including, without limitation, reasonable attorneys' fees and
expenses of Landlord and Lender and any revenue, documentary stamp or intangible
taxes. Upon the completion of Tenant's purchase of the Premises but not prior
thereto (whether or not any delay or failure in the completion of such purchase
shall be the fault of Landlord), this Lease shall terminate except with respect
to obligations and liabilities of Tenant hereunder, actual or contingent, which
have arisen on or prior to such completion of purchase.

3.3   Omitted.

3.4   Rejection of Rejectable Purchase Offer; Notice to Lender of Rejectable
Purchase Offer.

      (a)   So long as a loan which is secured by a first mortgage lien on
Landlord's interest in the Premises (hereinafter, a "Loan") is outstanding,
Tenant shall deliver to Lender, concurrently with the delivery thereof to
Landlord, a copy of any Rejectable Purchase Offer together with copies of all
items required to be delivered pursuant to Section 3.2(a) and (c).

      (b)   If the Landlord rejects a Rejectable Purchase Offer by a timely
written notice to the Tenant, then: (i) this Lease shall terminate on the Lease
Termination Date (ii) any Net Proceeds (other than those specifically relating
to the Tenant's Personal Property) payable in connection with the Condemnation
or Casualty (or the right to receive the same when made if payment therefor has
not yet been made) shall be assigned or paid and belong to the Landlord and
(iii) the Tenant shall pay to the Landlord all Basic Rent accrued as of such
Lease Termination Date and all other amounts then accrued or due and payable by
the Tenant under this Lease. During such time as an Indenture encumbers the
Premises, no rejection of a Rejectable Purchase Offer shall be effective unless
countersigned by the Lender.

3.5   Restoration.

      (a)   Following a Condemnation or Casualty for which Tenant is not
permitted to give or, if permitted, does not give notice of its intention to
terminate this Lease as provided in Section 3.2, this Lease shall continue in
full force and effect and Tenant shall, at its expense, promptly restore the
Premises in conformity with the requirements of Sections 2.5 and 3.7 (in the
case of Condemnation, as nearly as practicable) to the condition and fair market
value thereof immediately prior to such occurrence (or if the Premises were
under renovation at such time, to the planned condition and projected fair
market value thereof at the time of completion of renovation). Prior to

                                       13
<PAGE>
such restoration, Tenant shall deliver its reasonable estimate of the cost
thereof, which shall be subject to the approval of Landlord, which approval
shall not be unreasonably withheld (the cost approved by Landlord is referred to
as the "Restoration Cost").

      (b)   If the repair constitutes a Material Alteration, the Restoration
Cost must be confirmed by an architect reasonably acceptable to Landlord and
Lender (an "Architect").

      (c)   The Restoration Cost shall be paid first out of Tenant's own funds
to the extent that the Restoration Cost exceeds the Net Proceeds payable in
connection with such occurrence. To the extent that an Indenture requires that
Tenant or Landlord deliver its portion of the Restoration Costs to Lender (or
other security acceptable to Lender), Tenant shall deliver the same to Lender.
In addition, in such event the Restoration Cost shall be disbursed in accordance
with the procedure set forth in subsection (e) of this Section below. If the Net
Proceeds relate to a Casualty which is not a Major Casualty and no Event of
Default shall exist at the time of the Casualty or, at the time of disbursement
of Net Proceeds, then any Net Proceeds remaining after final payment has been
made for such work and after Tenant has been reimbursed for any portions it
contributed to the Restoration Cost shall be retained by Tenant so long as the
Premises are restored to the condition and market value thereof immediately
prior to the Casualty. If the Net Proceeds relate to a Major Casualty or if an
Event of Default has occurred and is continuing, Lender may apply any Net
Proceeds towards payment of an Indenture, which payment shall not relieve Tenant
of any of its obligations hereunder. If the Net Proceeds relate to a
Condemnation other than a Total or Major Condemnation, no adjustment shall be
made in the Basic Rent and the Net Proceeds remaining after final payment for
the work and after Tenant has been reimbursed for any portions it contributed to
the Restoration Cost shall be paid as follows: (i) to Lender until the
outstanding balance of a Loan allocable to the Premises has been paid in full
(ii) from any remaining Net Proceeds, the amount allocable to the loss of use of
the Premises during the remainder of the Primary Term (or if the Condemnation
occurs during an Extended Term, then the Net Proceeds allocable to loss of use
of the Premises during the remainder of the then current Extended Term) shall be
retained by Tenant, (iii) any balance shall be retained by Landlord. In the
event of any temporary Condemnation, this Lease shall remain in full force and
effect and the Net Proceeds shall be delivered to Landlord or, if required by an
Indenture, Lender, to be applied towards the payment of Basic Rent as the same
becomes due (with any balance delivered to Tenant and any deficiency payable by
Tenant); provided, however, that such portion of the Net Proceeds allocable to
the period after the expiration or termination of the Primary Term (or if the
Condemnation occurs during an Extended Term, then after the expiration of the
then current Extended Term) shall be paid to Landlord, or if required by an
Indenture, Lender. If the cost of any rebuilding, replacement or repair required
to be made by Tenant pursuant to this Section 3.5 shall exceed the amount of
such Net Proceeds, the deficiency shall be paid by Tenant. Tenant shall not be
entitled to disbursements of the Net Proceeds if an Event of Default has
occurred and is continuing.

                                       14
<PAGE>
      (d)   The Basic Rent and the Additional Rent payable under the provisions
of this Lease shall not be affected, altered or reduced by any Casualty or
Condemnation (except as specifically set forth in this Article with respect to a
termination of the Lease upon payment of the amounts required therein). Tenant's
obligation to continue to pay Basic Rent and Additional Rent shall continue
notwithstanding any such Condemnation or Casualty.

      (e)   If the Restoration Costs are required to be held by Landlord or
Lender pursuant to this Lease, then, as long as an Indenture is outstanding,
Landlord hereby directs that such Net Proceeds shall be held by Lender and shall
be paid out from time to time to Tenant as the work progresses (less any cost to
Lender or Landlord of recovering and paying out such proceeds, including,
without limitation, reasonable attorneys', trustees' or escrow fees relating
thereto and costs allocable to inspecting the work and the plans and
specifications therefor), subject to each of the following conditions:

            (i)   At the time of any disbursement, no Event of Default shall
exist and no mechanics' or materialmen's liens shall have been filed and remain
undischarged or unbonded.

            (ii)  Disbursements shall be made from time to time in an amount not
exceeding the hard and soft cost of the work and costs incurred since the last
disbursement upon receipt of (1) satisfactory evidence, including Architect's
certificates of the stage of completion, of the estimated cost of completion and
of performance of the work to date in a good and workmanlike manner in
accordance with the contracts, plans and specifications, (2) partial releases of
liens, and (3) other reasonable evidence of cost and payment so that Landlord
can verify that the amounts disbursed from time to time are represented by work
that is completed in place or delivered to the site and free and clear of
mechanic's lien claims.

            (iii) Each request for disbursement shall be accompanied by a
certificate of Tenant describing the work, materials or other costs or expenses,
for which payment is requested, stating the cost incurred in connection
therewith and stating that Tenant has not previously received payment for such
work or expense and the certificate to be delivered by Tenant upon completion of
the work shall, in addition, state that the work has been substantially
completed and complies with the applicable requirements of this Lease.

            (iv)  No disbursement made prior to final completion of any item of
work (in accordance with Section 3.7(a)(v)) shall cause the aggregate amount
disbursed with respect to such item of work to exceed 900 of the value of the
portion of such item of work which has been completed if, at the time of such
disbursement, (x) an Event of Default has occurred and is continuing, or (y)
neither tenant nor guarantor has an investment grade rating. As used herein
"Investment Grade Rating" shall mean a long term unsecured debt rating of BBB or
better by Fitch IBCA, Inc., or any successor thereto.

                                       15
<PAGE>
            (v)   Net Proceeds held by Landlord or Lender in accordance with
this Section shall be held in a separate federally insured interest bearing
account. Any interest earned on the Net Proceeds shall be a part of the Net
Proceeds, and shall be disbursed in accordance with this Lease.

      (f)   Notwithstanding any other provision of this Section, if either
Tenant or a Guarantor is then currently maintaining an Investment Grade Rating
and in Tenant's reasonable judgment the cost of the Work (as hereinafter
defined) is less than $500,000, such Work can be completed in less than one
hundred twenty (120) days (subject to Force Majeure) and no Event of Default has
occurred and is continuing and if allowed pursuant to the provisions of an
Indenture, then Landlord, upon request by Tenant, shall permit Tenant to apply
for and receive the Net Proceeds directly from the insurer or payor thereof (and
Landlord shall advise such insurer or payor and Lender to pay over such Net
Proceeds directly to Tenant), provided that Tenant shall promptly and diligently
commence and complete such Work in a good and workmanlike manner.

      (g)   If an Event of Default shall have occurred and be continuing or if
Tenant (i) shall fail to submit to Landlord for approval plans and
specifications (if required pursuant to Section 3.7(a)(i) hereof) for the Work
(approved by the Architect and by all governmental authorities whose approval is
required), (ii) after any such plans and specifications are approved by all such
governmental authorities, the Architect, Landlord and Lender, shall fail to
commence promptly such Work, (iii), shall fail to diligently prosecute such Work
to completion (after Lender or Landlord has released the Net Proceeds if and to
the extent provided for hereunder), or (iv) materially fail in any other respect
to comply with the Work obligations under this Section, then in addition to all
other rights available hereunder, at law or in equity, Landlord or Lender, or
any receiver of the Premises or any portion thereof, upon fifteen days prior
written notice to Tenant (except in the event of emergency in which case no
notice shall be required), may (but shall have no obligation to) perform or
cause to be performed such Work, and may take such other steps as either
Landlord or Lender deems advisable (but such performance shall not cure the
default of Tenant). In addition, if an Event of Default shall have occurred and
be continuing, Lender may apply, any Net Proceeds towards payment of a Loan,
which payment shall not relieve Tenant of any of its obligations hereunder.
Tenant hereby waives, for Tenant and all others holding under or through Tenant,
any claim, other than for gross negligence or willful misconduct, against
Landlord and Lender and any receiver arising out of any act or omission of
Landlord or Lender or such receiver pursuant hereto, and Landlord or Lender may
apply all or any portion of the Net Proceeds (without the need to fulfill any
other requirements forth in this Section) to reimburse Landlord or Lender or
such receiver, for all amounts incurred in connection with the Work, and any
costs not reimbursed to such parties shall be paid by Tenant to Landlord (or
such other party) on demand, together with interest thereon at the Default Rate
from the date such amounts are advanced until the same are paid by Tenant.

3.6   Insurance.

                                       16
<PAGE>
      (a)   Tenant will maintain insurance on the Premises of the following
types and amounts:

            (i)   Insurance against loss or damage to the Improvements and
Equipment under a fire and broad form of all risk extended coverage insurance
policy. Such insurance shall be in amounts sufficient to prevent Landlord or
Tenant from becoming a co-insurer under the applicable policies, and in any
event in amounts not less than the actual replacement cost of the Improvements
and Equipment (excluding footings and foundations and other parts of the
improvements which are not insurable) as determined from time to time at
Lender's request but not more frequently than once in any 12-month period, by
agreement of Landlord, Lender and Tenant, or if not so agreed, at Tenant's
expense, by the insurer or insurers or by an appraiser approved by Landlord.
Such insurance policies may contain reasonable and necessary exclusions and
deductible amounts not to exceed two percent of the Stipulated Loss Value.

            (ii)  Worker's compensation insurance to the extent required by the
law of the state in which the Premises are located.

            (iii) Insurance against loss or damage from explosion of any steam
or pressure boilers or similar apparatus located in or about the Improvements in
an amount not less than the actual replacement cost of the Improvements and
Equipment (excluding footings and foundations and other parts of the
Improvements which are not insurable).

            (iv)  Flood insurance in an amount equal to the full Replacement
Cost of the Premises or the maximum amount available through National Flood
Program or any successor program, whichever is less, if all or any portion of
the Premises are located in an area which has been designated by the Secretary
of Housing and Urban Development or by the Federal Emergency Management Agency
as having special flood hazards, and if flood insurance is available under the
National Flood Insurance Act.

            (v)   So long as a Loan is still outstanding, if the Premises or any
part thereof are situated in an area subsequently designated as a "Zone 3 or
Zone 4 Earthquake Zone" by the Uniform Building Code, earthquake insurance in an
amount equal to the replacement cost of the Improvements or the maximum amount
of earthquake insurance available, whichever is the lesser, unless Lender waives
this requirement in writing after review of a seismic report (prepared according
to Lender's requirements) provided to Lender by Tenant, at Tenant's expense.
Tenant represents that no part of the Premises are situated in an area currently
designated as a "Zone 3 or Zone 4 Earthquake Zone" by the Uniform Building Code.

            (vi)  Such other insurance (including without limitation, rent loss
insurance in an amount equal to twelve months Basic Rent) as may from time to
time be reasonably required by Landlord or, as required by an Indenture, by
Lender in order to protect their respective interests, provided that such
insurance is then customarily maintained by prudent owners or tenants with
respect to improvements similar in character, location, use and

                                       17
<PAGE>
occupancy to the Improvements or is then customarily required by prudent lenders
with respect to mortgage loans secured by similar properties.

            (vii) Tenant shall also maintain commercial general public liability
insurance insuring Tenant, with Landlord and Lender as additional insureds,
against claims for bodily injury and property damage or for loss of life arising
out of the occupation, ownership or use of the Premises, with coverage for
personal injury, bodily injury and property damage of not less than $30 million
combined single limit coverage per occurrence in the aggregate in any given
policy year, or such greater limits as may be required from time to time by
Landlord or, as required by an Indenture, Lender consistent with insurance
coverage on properties similarly constructed, occupied and maintained.

      (b)   Such insurance shall be issued by companies authorized to transact
business in the state in which the Premises are located and having an A.M. Best
Company rating of A or better and financial size category of not less than X,
and a Standard & Poor's rating of A or better as to claims paying ability,
provided that with respect to worker's compensation insurance such insurance
company must have an A.M. Best Company rating of A or better and financial size
category of not less than VIII. No casualty or other insurance policy maintained
by Tenant hereunder shall provide for a deductible or self-insured retention in
excess of $100,000.

      (c)   Every such policy (other than any general public liability or
worker's compensation policy) shall bear a mortgagee's loss payable clause or a
mortgagee endorsement in favor of Lender and each other mortgagee or beneficiary
(whether one or more, and together with its or their successors and assigns, the
"Junior Lenders") under each mortgage, deed of trust or similar security
instrument (other than an Indenture) creating a lien on the interests of
Landlord in the Premises (the "Junior Indentures"), and any loss under any such
policy shall be payable to Lender to be held and applied pursuant to this
Article 3.

      (d)   Each policy (other than worker's compensation policy) shall provide
that (i) it may not be canceled or materially changed except after 30 days prior
notice to Landlord, Lender and the Junior Lenders, (ii) any losses otherwise
payable thereunder shall be payable notwithstanding (A) any act or omission of
Landlord or Tenant which might, absent such provision, result in a forfeiture of
all or a part of such insurance payment, or (B) the occupation or use of any of
the Premises for purposes more hazardous than permitted by the provisions of
such policy and (iii) the insurer thereunder waives all rights of subrogation
against the Lender, Junior Lenders and Landlord and waives any right of set-off.

      (e)   Tenant shall pay as they become due all premiums for the insurance
required by this Section 3.6, shall renew or replace each policy, and shall
deliver to Landlord, Lender and the Junior Lenders a certificate or other
evidence (reasonably satisfactory to Lender and Landlord) of the existing policy
and such renewal or replacement policy at least thirty days prior to the Policy
Expiration Date (as herein defined) of each policy. Each

                                       18
<PAGE>
such policy shall provide that it shall not expire or terminate until the
Landlord, Lender and Junior Lenders shall receive a notice from the insurer to
the effect that a policy will expire on a date (the "Policy Expiration Date")
which shall be thirty (30) days following the date of the receipt by Landlord,
Lender and Junior Lenders of such notice. In the event of Tenant's failure to
comply with any of the foregoing requirements of this Section 3.6 within five
(5) business days of the giving of the written notice by Landlord to Tenant,
Landlord shall be entitled to procure such insurance. Any sums expended by
Landlord in procuring such insurance shall be Additional Rent and shall be
repaid by Tenant, together with interest thereon at the Default Rate, from the
time of payment by Landlord until fully paid by Tenant immediately upon written
demand therefor by Landlord.

      (f)   Anything in this Article 3 to the contrary notwithstanding, any
insurance which Tenant is required to obtain pursuant to Section 3.6 may be
carried under a "blanket" policy or policies covering other properties or
liabilities of Tenant, provided that such "blanket" policy or policies otherwise
comply with the provisions of this Section and includes an agreed upon amount
endorsement for the Premises in an amount not less than the Stipulated Loss
Value less the value of the Land and the footings, foundations and other parts
of the Improvements which are not insurable. In the event any such insurance is
carried under a blanket policy, Tenant shall deliver to Landlord and Lender
evidence of the issuance and effectiveness of the policy, the amount and
character of the coverage with respect to the Premises and the presence in the
policy of provisions of the character required in this Section 3.6.

      (g)   Any loss under any property damage insurance required to be
maintained by Tenant shall be adjusted by Landlord, Lender and Tenant pursuant
to the provisions of Section 3.2(a), provided, however, if an Event of Default
shall have occurred and be continuing, Landlord and Lender shall have the sole
right to make such adjustment and collection, but Tenant shall be entitled to
any proceeds relating to Tenant's Personal Property (subject to Landlord's right
to offset any amounts owed to Landlord under this Lease).

      (h)   The requirements of this Section shall not be construed to negate or
modify Tenant's obligations under Section 2.4.

3.7   Alterations.

      (a)   Tenant may, at its expense, make additions to and alterations of the
Improvements, and construct additional Improvements (collectively,
"Alterations"), provided that (1) the fair market value, utility and useful life
of the Premises shall not be reduced or lessened in any material respect
thereby, (2) such Alterations shall be expeditiously completed in a good and
workmanlike manner, free and clear of liens and encumbrances, and in compliance
with all applicable Legal Requirements and the requirements of all insurance
policies required to be maintained by Tenant hereunder, (3) Tenant shall not
make any Alterations in violation of the terms of any restriction, easement,
condition, covenant or other matter affecting title to or use of the Premises
and (4) no Material Alterations (as hereinafter defined), shall

                                       19
<PAGE>
be made unless Landlord's and Lender's prior written consent shall have been
obtained, which consent shall not be unreasonably withheld, delayed or
conditioned, unless an Event of Default shall have occurred and be continuing in
which case such consent may be withheld by Landlord or Lender in its sole
discretion. "Material Alteration" is defined as Work that reduces the footprint
or rentable square footage of the Improvements or the parking area or for which
the estimated cost is in excess of $350, 000 multiplied by 1.015 raised to the n
power where n is the number of whole (12 month) years that have elapsed since
the Commencement Date and prior to commencement of Work. In addition to the
limitations set forth in (1) through (4) above, Tenant agrees that all
Alterations, Material Alterations, restoration, repair and any other work which
Tenant shall be required or permitted to do under the provisions of this Lease
(hereinafter collectively called the "Work") shall be performed in each case
subject to the following:

            (i)   No Material Alterations shall be commenced until detailed
plans and specifications (including layout, architectural, mechanical and
structural drawings), prepared by an Architect shall have been submitted to and
approved by Landlord and, if a Loan is outstanding, Lender, and no such Work
shall be undertaken except under the supervision of the Architect.

            (ii)  All Work shall be commenced only after all required municipal
and other governmental permits, authorizations and approvals shall have been
obtained by Tenant, at its own cost and expense.

            (iii) If the Work shall constitute a Material Alteration, it shall
not be commenced until Tenant shall have obtained and delivered to Landlord, and
as required by an Indenture, Lender, either (A) a performance bond and a labor
and materials payment bond (issued by a corporate surety licensed to do business
in the state in which the Premises are located and satisfactory to Landlord and,
as required by an Indenture, Lender), each in an amount equal to the estimated
cost of such Work and in form otherwise satisfactory to Landlord, and as
required by an Indenture, Lender, or (B) such other security as shall be
reasonably satisfactory to Landlord, and as required by an Indenture, Lender;
provided, however, that if at the time the Work is commenced, either Tenant or a
Guarantor then maintains and continues to maintain until such Work is completed
an Investment Grade Rating and no Event of Default shall have occurred and be
continuing and estimated cost of the Work does not exceed $1 million, Tenant
shall not be required to comply with this subsection (iii).

            (iv)  Subject to the terms of Section 2.6 hereof, the cost of all
Work shall be paid promptly, in cash, so that the Premises and Tenant's
leasehold estate therein shall at all times be free from (A) liens for labor or
materials supplied or claimed to have been supplied to the Premises or Tenant,
and (B) chattel mortgages, conditional sales contracts, title retention
agreements, security interest and agreements, and financing agreements and
statements.

            (v)   Upon completion of any Work, Tenant, at Tenant's expense,
shall obtain certificates of final approval of such Work required by any

                                       20
<PAGE>
governmental authority and shall furnish Landlord with copies thereof, and, if
the Work constituted Material Alterations, together with " as-built " plans and
specifications for such Work.

            (vi)  Any Work shall be subject to inspection at any time and from
time to time by any of Landlord or, as required by an Indenture, Lender, their
respective architect(s), or their duly authorized construction representatives,
and if any such party upon any such inspection shall be of the opinion that the
Work is not being performed in accordance with the provisions of this Section or
the plans and specifications, or that any of the materials or workmanship are
unsound or improper, Tenant shall correct any such failure and shall replace any
unsound or improper materials or workmanship. Anything contained herein to the
contrary notwithstanding, any different procedure for the performance of Work
which may be required under any Indenture shall take precedence over and be in
addition to the procedures provided for in this Lease.

            (vii) Except as may be expressly provided to the contrary hereunder
with respect to Tenant's Personal Property, all Alterations installed in or upon
the Premises at any time during the Term shall become the property of Landlord
and shall remain upon and be surrendered with the Premises unless Landlord, by
notice to Tenant no later than ninety (90) days prior to the scheduled
expiration (or within 90 days after any earlier termination) of this Lease,
elects to have the same removed or demolished by Tenant, in which event, the
same shall be removed from the Premises by Tenant prior to the scheduled
expiration (or within 90 days after any earlier termination) of this Lease, at
Tenant's expense. Landlord shall not require Tenant to remove or demolish any
Alterations unless in Landlord's reasonable judgment, such Alterations (A)
materially reduce the fair market value or fair market rent of the Premises (B)
are functionally obsolete (C) are special purpose or (D) are in violation of
then applicable law. Tenant may expressly request in Tenant's written request
for consent that Landlord determine its election prior to installation (which
written request shall include the estimated cost of removal and restoration).
Tenant shall immediately repair any damage to the Premises caused by its removal
of any of Tenant's Personal Property or Alterations that remain the property of
Tenant pursuant to the terms of this Section. All property permitted or required
to be removed by Tenant at the end of the Term remaining in the Premises after
Tenant's removal shall be deemed abandoned and may, at the election of Landlord,
either be retained as Landlord's property or may be removed from the Premises by
Landlord at Tenant's expense. The provisions of this Section shall survive the
expiration or earlier termination of the Term.

      (b)   Tenant may, at its cost and expense, install, or place upon or
reinstall, or replace and remove from the Premises any Tenant's Personal
Property.

3.8   Easements.

                                       21
<PAGE>
      (a)   Landlord agrees to enter into, at Tenant's expense, such easements,
covenants, waivers, approvals or restrictions for utilities, parking or other
matters as desirable for operation of the Premises or properties adjacent
thereto (collectively, "Easements") as reasonably requested by Tenant, subject
to Lender's and Landlord's approval of the form thereof, not to be unreasonably
withheld or delayed; provided, however, that no such Easement shall result in
any reduction in parking or any diminution in the value or utility of the
Premises for its current use and further provided that no such Easement shall
render the use of the Premises dependent upon any other property or condition
the use of the Premises upon the use of any other property, each of which Tenant
shall certify to Landlord and Lender in writing delivered with Tenant's request
with respect to such Easement. Tenant shall pay Landlord's and Lender's
reasonable attorney's fees and other out-of-pocket expenses and Lender's
customary fees incurred in connection with any request made by Tenant hereunder.

      (b)   Tenant agrees that Tenant is obligated to and shall perform all
obligations of the owner of the Premises under and pay all expenses which the
owner of the Premises may be required to pay in accordance with any reciprocal
easement agreement or any other agreement or document of record now affecting
the Premises, herein referred to collectively as the "REA", and that Tenant
shall comply with all of the terms and conditions of the REA during the term of
this Lease. Tenant further covenants and agrees to indemnify, defend and hold
harmless Landlord and Lender against any claim, loss or damage suffered by
Landlord or Lender by reason of Tenant's failure to perform any obligations or
pay any expenses as required under any REA or comply with the terms and
conditions of any REA as hereinabove provided during the term of this Lease.

3.9   Equipment. Tenant acknowledges that the Equipment is the property of
Landlord and that Landlord has granted, and may hereafter grant, a security
interest therein to Lender. Tenant hereby represents and warrants to Landlord
that the Equipment is free and clear of any and all liens, security interests or
other encumbrances as of the date hereof, other than the lien and security
interest of an Indenture. Tenant hereby agrees to maintain the Equipment in good
condition and repair. In no event shall any of the Landlord's Equipment be
discarded or removed from the Premises unless such Equipment is replaced by
similar Equipment with a value at least equal to the value of the replaced
Equipment. Notwithstanding the foregoing, at the end of the Primary Term, Tenant
may remove any radiology, laboratory, diagnostic, treatment and other medical
equipment so long as (a) such equipment is readily removable without material
damage and (b) as part of such removal, Tenant restores the Premises to like-new
condition.

                                   ARTICLE 4.

4.1   Assignment and Subletting.

      (a)   So long as no Event of Default shall have occurred and be
continuing, Tenant may sublet the Premises (including, but not limited to,

                                       22
<PAGE>
subleases to affiliates of Tenant) and in connection therewith cause such
sublessee to perform Tenant's obligations hereunder; provided, however, (i) each
such sublease shall expressly be made subject to the provisions hereof, (ii) the
term of any subletting shall not extend beyond the Term of this Lease, (iii) no
sublease shall affect or reduce any obligation of the Tenant or right of the
Landlord hereunder, (iv) all obligations of the Tenant hereunder shall continue
in full force and effect as the obligations of a principal and not of a
guarantor or surety, as though no subletting had been made and (v) so long as a
Loan is outstanding, Tenant may not sublet the Premises to any entity
unaffiliated with Tenant if the aggregate rentable square feet covered by such
sublease and all other subleases to entities unaffiliated with Tenant exceeds
ten percent of the total rentable square feet in the Improvements (except with
Lender's written consent which shall not be unreasonably withheld). Neither this
Lease nor the term hereby demised shall be mortgaged or pledged by Tenant, nor
shall Tenant mortgage or pledge its interest in any sublease of any portion of
the Premises or the rentals payable thereunder. Any such mortgage or pledge, any
sublease made other than as expressly permitted by this Section 4.1, and any
assignment of Tenant's interest hereunder made other than as expressly permitted
by this Section 4.1, shall be void. Tenant shall, within 10 days after the
execution of any sublease, deliver a conformed copy thereof to Landlord and
Lender.

      (b)   So long as no Event of Default shall have occurred and be
continuing, Tenant may assign this Lease or merge with another entity, or a
change in control of Tenant may occur provided, however, (i) each such
assignment shall expressly be made subject to the provisions hereof, (ii)
Guarantor shall specifically approve such assignment or change in control of
Tenant or Tenant merger and shall confirm in writing its continuing obligations
under its guaranty, (iii) Tenant (and in the case of any Tenant merger, the
surviving entity) and Guarantor shall deliver such estoppels, certificates,
opinions of counsel (concerning the continuing enforceability of this Lease, any
Subordination, Non-Disturbance and Attornment Agreement in effect immediately
prior to the assignment, change in control or merger and Guarantor's guaranty
and any other document assigned thereby), and other instruments as may be
reasonably required by Landlord or, as required by an Indenture, Lender, (iv)
the assignee (or in the case of a Tenant merger, the surviving entity) shall
specifically assume all obligations of Tenant under this Lease and under any
other agreement of Tenant related hereto or thereto, (v) all obligations of the
Tenant hereunder shall continue in full force and effect as the obligations of a
principal and not of a guarantor or surety, as though no assignment had been
made, (vi) the assignee (or in the case of a Tenant merger, the surviving
entity) must be a solvent entity, (vii) the assignee (or in the case of a Tenant
merger, the surviving entity) must either be an entity formed in the United
States or must specifically consent to jurisdiction in Nevada, and must provide
an opinion in form reasonably acceptable to Landlord and, as required by an
Indenture, to Lender that such consent to jurisdiction is enforceable and valid
(viii) in the case of a Tenant merger or change in control of Tenant, at least
30 days prior to the merger or change in control, tenant must have notified
Landlord and Lender of the material terms of the merger or change in control and
(ix) so long as a Loan is outstanding, any assignment, change in control of
Tenant or Tenant

                                       23
<PAGE>
merger involving an entity unaffiliated with Tenant shall not be permitted
without the prior written consent of Landlord and Lender which shall not be
unreasonably withheld. Upon Landlord's and Lender's receipt of Tenant's written
request for consent together with all material terms of the assignment, change
in control or merger and such other information that Lender shall reasonably
request (which request shall be made within five Business Days after receipt of
Tenant's written request and such material terms), Landlord and Lender shall
have fifteen Business Days to respond. Failure to respond within such time shall
be deemed consent. If Lender or Landlord disapproves any such transaction, it
shall provide Tenant in writing the reasons for disapproval in reasonable
detail. In determining whether consent is reasonable, the following criteria
shall be considered:

      (A)   The overall financial responsibility of the new tenant.

      (B)   Whether the proposed use of the Premises would be similar to the
current Tenant's use.

      (C)   The proposed new tenant's suitability to use the Premises.

      (D)   The expected economic feasibility of the proposed new tenant to meet
the current Tenant's Lease obligations.

      (E)   The level of experience of the new tenant in operating and managing
buildings similar in character, age and size to the Premises.

      A certified copy of the executed assignment or merger document approved by
Landlord shall be provided to Landlord and Lender within ten (10) days after the
execution thereof.

      (c)   Except in compliance with Section 4.1 (a) or (b), neither this
Lease, nor any interest of Tenant in this Lease or in the Premises, shall be
sold, assigned, or otherwise transferred, directly or indirectly, whether by
operation of law or otherwise, nor shall any of the issued or outstanding
capital stock of Tenant be sold, assigned or transferred, nor shall additional
stock in Tenant be issued if the issuance of additional stock will result in a
change of the controlling stock ownership of Tenant as held by the shareholders
thereof on the date hereof (or on the date that Landlord approved the transfer
to the holder of Tenant's leasehold interest in this Lease). The transfer of
stock of Tenant for the purposes of this Section 4.1 shall not include the sale,
issuance or exchange of shares, which sale, issuance or exchange is effected
through the "over-the-counter market" or through any recognized stock exchange.
In no event shall any assignment, sublease or license relieve Tenant of any
liability or obligation under this Lease, which shall be and remain that of a
primary obligor and not a guarantor or surety. For the purposes of this Article
and Section 5.1(a), "control" or "controlling" means the power to direct the
management and policies of the applicable party, directly or indirectly, whether
through ownership of voting securities or other beneficial interests, by
contract or otherwise.

                                       29
<PAGE>
      (d)   Without implying any authority of Tenant to assign this Lease, if
this Lease is assigned whether or not pursuant to the provisions hereof,
Landlord may collect rent from the Assignee, or if the Premises or any part
thereof are sublet or occupied by any person or entity other than Tenant,
Landlord may, after an Event of Default has occurred and is continuing, collect
rent from the subtenant or occupant, and in all such cases apply the net amount
collected to the Basic Rent and Additional Rent herein reserved. However, no
such assignment, subletting, occupancy or collection shall be deemed a waiver of
the provisions of this Article, or the acceptance of the assignee, subtenant or
occupant as Tenant, or a release of Tenant from the further performance by
Tenant of the terms, covenants, and conditions on the part of Tenant to be
observed or performed hereunder, and, subsequent to any assignment or
subletting, Tenant's liability hereunder shall continue notwithstanding any
subsequent modification or amendment hereof or the release of any subsequent
tenant hereunder from any liability, to all of which Tenant hereby consents in
advance.

                                   ARTICLE 5.

5.1   Conditional Limitations; Default Provisions.

      (a)   Any of the following occurrences or acts shall constitute an "Event
of Default" under this Lease:

            (i)   if Tenant shall (1) fail to pay any Basic Rent, Additional
Rent or other sum as and when required to be paid by Tenant hereunder, and such
failure shall continue for three Business Days after written notice to Tenant of
such default, or (2) fail to observe or perform any other provision hereof
(other than those specified in clauses (ii)-(x) of this subsection 5.1(a)) and
such failure shall continue for thirty (30) days after written notice to Tenant
of such failure (provided, that in the case of any such failure which is capable
of being cured but cannot be cured by the payment of money and cannot with
diligence be cured within such 30-day period, if Tenant shall commence promptly
to cure the same and thereafter prosecute the curing thereof with diligence, the
time within which such failure may be cured shall be extended for such period as
is necessary to complete the curing thereof with diligence, but in no event to
exceed 180 days from the date of such original failure); or

            (ii)  if any representation or warranty of Tenant or Guarantor set
forth herein or in any notice, certificate, demand, request or other document or
instrument delivered to Landlord in connection with this Lease shall prove to be
incorrect in any material respect as of the time when the same shall have been
made; or

            (iii) if Tenant or Sierra Health Services, Inc., a Nevada
corporation ("Guarantor") shall file a petition in bankruptcy or for
reorganization or for an arrangement, administration, liquidation or
receivership pursuant to any federal or state law (or any other law governing

                                       25
<PAGE>
Guarantor), or shall be adjudicated a bankrupt or become insolvent or shall make
an assignment for the benefit of creditors or shall admit in writing its
inability to pay its debts generally as they become due, or if a petition or
answer proposing the adjudication of Tenant or Guarantor as a bankrupt or its
reorganization pursuant to any federal or state bankruptcy, liquidation,
voluntary administration, administration, receivership, moratorium or trust law
or any similar federal or state law shall be filed in any court and Tenant or
Guarantor shall consent to or acquiesce in the filing thereof or such petition
or answer shall not be discharged or denied within ninety (90) days after the
filing thereof; or

            (iv)  if a receiver, trustee, administrator or liquidator of Tenant
or Guarantor or of all or substantially all of the assets of Tenant or Guarantor
or of the Premises or Tenant's estate therein shall be appointed in any
proceeding brought by Tenant or Guarantor, or if any such receiver, trustee or
liquidator shall be appointed in any proceeding brought against Tenant or
Guarantor and shall not be discharged within ninety (90) days after such
appointment, or if Tenant or Guarantor shall consent to or acquiesce in such
appointment; or

            (v)   if Guarantor shall dissolve or otherwise fail to maintain its
legal existence; or

            (vi)  if Tenant shall default under Section 4.1 of this Lease; or

            (vii) if Guarantor shall default under the provisions of its
guaranty;

            (viii) if an Event of Default shall occur and continue under any of
the leases set forth in Schedule G and the landlord thereunder is the same as,
or is an affiliate of, the Landlord under this Lease; or

            (ix)  if Tenant shall fail to maintain or replace any insurance
required to be maintained or replaced by Tenant in accordance with the terms and
conditions of Section 3.6 hereof; or

            (x)   if Tenant shall dissolve or otherwise fail to maintain its
legal existence unless such dissolution or termination of Tenant's legal
existence occurs in connection with a merger completed in accordance with
Section 4.1(b).

            (As used in Section 5.1 (a) (viii), an entity is an "affiliate" of
Landlord if such entity controls, is controlled by, or is under common control
with, Landlord or any entity controlling Landlord.)

      (b)   If an Event of Default shall have occurred and be continuing
Landlord shall be entitled to all remedies available at law or in equity.
Without limiting the foregoing, Landlord (with Lender's consent) shall have the
right to give Tenant notice of Landlord's termination of the term of this Lease.
Upon the giving of such notice, the term of this Lease and the estate hereby
granted shall expire and terminate on such date as fully and

                                       26
<PAGE>
completely and with the same effect as if such date were the date herein fixed
for the expiration of the term of this Lease, and all rights of Tenant hereunder
shall expire and terminate, but Tenant shall remain liable as hereinafter
provided.

      (c)   If an Event of Default shall have occurred and be continuing,
Landlord shall have the immediate right, whether or not the term of this Lease
shall have been terminated pursuant to Section 5.1(b), to re-enter and
repossess the Premises and the right to remove all persons and property
therefrom by summary proceedings, ejectment, any other legal action or in any
lawful manner Landlord determines to be necessary or desirable, so long as
Landlord is proceeding in accordance with applicable law and, if required under
applicable law, under authority of a court of proper jurisdiction. Landlord
shall be under no liability by reason of any such re-entry, repossession or
removal. No such re-entry, repossession or removal shall be construed as an
election by Landlord to terminate this Lease unless a notice of such termination
is given to Tenant pursuant to Section 5.1(b).

      (d)   At any time or from time to time after a re-entry, repossession or
removal pursuant to Section 5.1(c), whether or not the term of this Lease shall
have been terminated pursuant to Section 5.1(b), Landlord may (but shall be
under no obligation to) relet the Premises for the account of Tenant, in the
name of Tenant or Landlord or otherwise, without notice to Tenant, for such term
or terms and on such conditions and for such uses as Landlord, in its absolute
discretion, may determine. Landlord may collect any rents payable by reason of
such reletting. Landlord shall not be liable for any failure to relet the
Premises or for any failure to collect any rent due upon any such reletting.

      (e)   No expiration or earlier termination of the term of this Lease
pursuant to Section 5.1(b), by operation of law or otherwise, and no reentry,
repossession or removal pursuant to Section 5.1(c) or otherwise, and no
reletting of the Premises pursuant to Section 5.1(d) or otherwise, shall relieve
Tenant of its liabilities and obligations hereunder, all of which shall survive
such expiration, termination, re-entry, repossession, removal or reletting.

      (f)   In the event of the expiration or earlier termination of the term of
this Lease or re-entry or repossession of the Premises or removal of persons or
property therefrom by reason of the occurrence of an Event of Default, and
subject to applicable law, Tenant shall pay to Landlord all Basic Rent,
Additional Rent and other sums required to be paid by Tenant, in each case
together with interest thereon at the Default Rate from the due date thereof to
and including the date of such expiration, termination, re-entry, repossession
or removal; and thereafter, Tenant shall, until the end of what would have been
the term of this Lease in the absence of such expiration, termination, re-entry,
repossession or removal and whether or not the Premises shall have been relet,
be liable to Landlord for, and shall pay to Landlord, as damages: (i) all Basic
Rent, Additional Rent and other sums which would be payable under this Lease by
Tenant in the absence of any such expiration, termination, re-entry,
repossession or removal, less (ii) the net

                                       27

<PAGE>
proceeds, if any, of any reletting effected for the account of Tenant pursuant
to Section 5.1(d), after deducting from such proceeds all expenses of Landlord
in connection with such reletting (including, without limitation, all
repossession costs, brokerage commissions, reasonable attorneys' fees and
expenses (including fees and expenses of appellate proceedings), employees'
expenses, alteration costs and expenses of preparation for such reletting).
Tenant shall pay such damages on the dates on which Basic Rent would be payable
under this Lease in the absence of such expiration, termination, re-entry,
repossession or removal, and Landlord shall be entitled to recover the same from
Tenant on each such date.

         (g) At any time after any such expiration or earlier termination of the
term of this Lease or re-entry or repossession of the Premises or removal of
persons or property thereon by reason of the occurrence of an Event of Default,
whether or not Landlord shall have previously collected any damages pursuant to
Section 5.1(f), Landlord shall be entitled to recover from Tenant, and Tenant
shall pay to Landlord on demand, as additional damages for Tenant's default and
in lieu of damages beyond the date of such demand as outlined in Section 5.1(f)
above, an amount equal to the excess, if any, of (a) the aggregate of all Basic
Rent, Additional Rent and other sums which would be payable under this Lease, in
each case from the date of such demand (or, if it be earlier, the date to which
Tenant shall have satisfied in full its obligations to pay damages under Section
5.1(f)) for what would be the then-unexpired Term in the absence of such
expiration, termination, re-entry, repossession or removal, discounted at a rate
equal to the then yield on U.S. Treasury obligations of comparable maturity to
the Term (the "Treasury Rate") over (b) the then fair rental value of the
Premises for what would be such then unexpired term of this Lease, discounted at
the Treasury Rate for the same period (such excess being hereinafter referred to
as "Future Rental Damages"). For purposes of determining value pursuant to this
Section 5.1(g), the following shall apply: (a) determinations of fair rental
value shall be made by an Appraiser (engaged by Landlord), with copies of such
determinations and supporting analysis to be provided to Tenant; and (b) all
determinations of Future Rental Damages shall be binding on Tenant in the
absence of manifest error. If any law shall limit the amount of Future Rental
Damages to less than the amount above agreed upon, Landlord shall be entitled to
the maximum amount allowable under such law.

5.2 Additional Rights of Landlord.

         (a) No right or remedy hereunder shall be exclusive of any other right
or remedy, but shall be cumulative and in addition to any other right or remedy
hereunder or now or hereafter existing. Failure to insist upon the strict
performance of any provision hereof or to exercise any option, right, power or
remedy contained herein shall not constitute a waiver or relinquishment thereof
for the future. Receipt by Landlord of any Basic Rent, Additional Rent or other
sums payable hereunder with knowledge of the breach of any provision hereof
shall not constitute waiver of such breach, and no waiver by landlord of any
provision hereof shall be deemed to have been made unless made in writing duly
executed by Landlord. Landlord shall be entitled to injunctive relief in case of
the violation, or attempted or

                                       28
<PAGE>
threatened violation, of any of the provisions hereof, or to a decree compelling
performance of any of the provisions hereof, or to any other remedy allowed to
Landlord by law or equity.

         (b) Tenant hereby waives and surrenders for itself and all those
claiming under it, including creditors of all kinds, (i) any right and privilege
which it or any of them may have to redeem any portion of the Premises or to
have a continuance of this Lease after termination of Tenant's right of
occupancy by order or judgment of any court or by any legal process or writ, or
under the terms of this Lease, or after the termination of the term of this
Lease as herein provided, and (ii) the benefits of any law which exempts
property from liability for debt or for distress for rent.

         (c) If Tenant shall be in default in the observance or performance of
any term or covenant on Tenant's part to be observed or performed under any of
the provisions of this Lease, then, without thereby waiving such default,
Landlord may, but shall be under no obligation to, take all action, including,
without limitation, entry upon the Premises to perform the obligation of Tenant
hereunder immediately and without notice in the case of an emergency and upon 5
days' written notice to Tenant in other cases. All expenses incurred by Landlord
in connection therewith, including attorneys' fees and expenses (including those
incurred in connection with any appellate proceedings), together with interest
thereon at the Default Rate from the date any such expenses were incurred by
Landlord until the date of payment by Tenant, shall constitute Additional Rent
and shall be paid by Tenant to Landlord upon demand.

         (d) If Tenant shall be in default in the performance of any of its
obligations hereunder, Tenant shall pay to Landlord or Lender, as appropriate,
on demand, all expenses incurred by Landlord or Lender as a result thereof,
including reasonable attorneys' fees and expenses (including those incurred in
connection with any appellate proceedings) and any Makewhole Premium incurred by
Landlord. If Landlord or Lender shall be made a party to any litigation
commenced against Tenant and Tenant shall fail to provide Landlord or Lender
with counsel reasonably approved by Landlord or Lender, as applicable, and pay
the expenses thereof, Tenant shall pay all costs and reasonable attorneys' fees
and expenses in connection with such litigation (including fees and expenses
incurred in connection with any appellate proceedings) together with interest at
the Default Rate, from the date paid by Landlord or Lender until reimbursed by
Tenant.

         (e) So long as a Loan is outstanding, if an Event of Default shall
exist, within five days after written demand from Landlord or Lender, Tenant
shall make monthly tax and insurance payments into an escrow account in
accordance with the applicable provisions of an Indenture for so long as such
Event of Default shall continue to exist.

6.2 Estoppel Certificates, Financial Information.

         (a) Tenant shall at any time and from time to time during the term of
this Lease within five Business Days after written request by Landlord, execute,
acknowledge and deliver to Landlord or to any prospective purchaser, assignee or
mortgagee or third party designated by Landlord, a certificate stating: (i) 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); (ii) the date to which Basic Rent has
been paid; (iii) whether there is any existing default by the Tenant in the
payment of Basic Rent, whether there is an existing default by the Tenant in the
payment of any Additional Rent beyond any applicable grace period, and whether
there is any other existing default or Event of Default by either party hereto,
and, if there is any such default, specifying the nature and extent thereof and
the action taken to cure such default; (iv) whether there are any actions or
proceedings pending against the Premises before any governmental authority to
condemn the Premises or any portion thereof or any interest therein and whether,
to the knowledge of Tenant, any such actions or proceedings have been
threatened; (v) whether there exists any material unrepaired damage to the
Premises from fire or other casualty; (vi) whether, to the knowledge of Tenant,
there is any existing default by Landlord under this Lease; and (vii) other
items that may be reasonably requested. Any such certificate may be relied upon
by any actual or prospective mortgagee or purchaser of the Premises.

         (b) Tenant shall submit to Landlord and if a Loan is outstanding,
Lender, when filed with the Securities and Exchange Commission, copies of
Tenant's (if it should go public) and Guarantor's Forms 10Q and 10K. If at any
time either Tenant or Guarantor is not a public company, Tenant shall submit to
Lender financial statements consistent with those provided to its lenders and
Tenant shall furnish to Lender: in case Tenant is not a public company, Tenant's
(or if Tenant is a member of Guarantor's consolidated group

                                       31
<PAGE>
and Tenant's financials are not separately audited, then Guarantor's) annual
audited financial report within one hundred twenty (120) days following the
close of Tenant's fiscal year and in case Guarantor is no longer a public
company, Guarantor's quarterly unaudited financial report within sixty days
following the close of Guarantor's fiscal quarter and Guarantor's annual audited
financial report within 120 days following the close of Guarantor's fiscal year.

           (c) Landlord shall promptly notify Tenant of the name and address of
 any Lender if different from that set forth in Section 6.1. Upon request of
 Landlord, and upon concurrent compliance with the provisions of Section 6.2(d)
 below, Tenant shall enter into an agreement with any Lender pursuant to which
 Tenant shall agree:

                    (i) that in the event that any such Lender, or any purchaser
 at a foreclosure sale, shall acquire title to the Premises, Tenant shall attorn
 to such Lender or such purchaser, as the case may be, as its new Landlord and
 this Lease shall continue as a direct lease between Tenant and such Lender or
 purchaser, as the case may be, with respect to the Premises upon the terms and
 conditions set forth herein except that such Lender or purchaser, as the case
 may be, shall not be liable to Tenant for any actions or omissions of Landlord
 prior to the date such Lender or purchaser, as the case may be, acquired title
 to the Premises;

                  (ii) Tenant shall not enter into any agreement with Landlord
for the termination of this Lease unless Tenant receives the written consent of
the Lender to such termination;

                  (iii) no rejection by Landlord of any Rejectable Purchase
offer pursuant to this Lease shall be effective unless Tenant receives the
written consent of the Lender to such rejection;

                  (iv) this Lease shall be subject and subordinate to the lien
of such Indenture;

                  (v) no consent to the release of Tenant from liability under
this Lease upon assignment of this Lease or sublease of the Premises shall be
effective unless Tenant shall receive the written consent of such Lender;

                  (vi) no subordination, amendment or modification of this Lease
shall be effective unless Tenant receives the written consent of the Lender
thereto and written evidence in writing from the applicable rating agencies, if
any, that any such action shall not result in a withdrawal, qualification or
downgrade of the current ratings for any securities issued in connection with
any securitization or other secondary market transaction in which the
indebtedness secured by an Indenture is included; and

                  (vii) Tenant will not pay any installment of Basic Rent more
than one month in advance of the due date thereof or otherwise than in the
manner provided for in this Lease.

                                       32
<PAGE>
                  (viii) to the other material terms for the benefit of the
current Lender set forth in the Subordination, Non-Disturbance and Attornment
Agreement entered into concurrently with the commencement of this Lease.

         (d) Upon receipt of a request from Landlord for the agreement described
in Section 6.2(c) above, Tenant's obligations under Section 6.2(c) above shall
be conditioned upon such Lender entering into a subordination, non-disturbance
and attornment agreement in customary form acceptable to Lender which shall
incorporate the agreement described in Section 6.2(c) and provide that unless
an Event of Default then exists under this Lease, Lender shall not join Tenant
as a defendant in any action to foreclose upon the interest of Landlord in the
Premises and, upon the Lender's foreclosure of Landlord's interest in the
Premises by judicial proceedings or otherwise, such Lender or other purchaser at
the foreclosure sale shall not be entitled to, nor shall it seek to terminate
this Lease or Tenant's interest in the Premises, provided, that, Tenant, from
and after the date of such succession, attorns to such Lender or purchaser, pays
to such Lender or purchaser all items of Basic Rent, Additional Rent and other
items accruing from and after such date and otherwise remains in compliance with
all other terms and provisions of this Lease. In the event that Tenant shall
execute a separate document for the benefit of a Lender relating to
subordination, attornment or non-disturbance, such document shall control to the
extent that it conflicts with the provisions of this Section 6.2(d).

                  (ii) no notices, complaints or orders of violation or
non-compliance with Environmental Laws have been received by Tenant and, to the
best of Tenant's actual knowledge, no federal, state or local environmental

prior owner for the generation, manufacture, storage, handling, transfer,
treatment, recycling, transportation, processing, production, refinement or
disposal (each, a "Regulated Activity ") of any material, waste or substance
which is (1) included within the definitions of "hazardous substances,"
"hazardous materials," "toxic substances," or "solid waste" in or pursuant to
any Environmental Law, or subject to regulation under any Environmental Law; (2)

connection with its acquisition of the Premises, the Premises are free of
Hazardous Substances and friable asbestos, the removal of which is required or

Premises and in commercially reasonable quantities as a consumer thereof,
subject to, in any event, compliance with Environmental Laws), (iii) shall not
install or permit the installation on the Premises of any underground storage
tanks or surface impoundments and shall not knowingly permit there to exist any
petroleum contamination in violation of applicable Environmental Laws
originating on or off the Premises (other than in connection with the use,
operation and maintenance of the premises and then only in compliance with
applicable Environmental Laws and all other applicable laws, rules, orders,
ordinances, regulations and requirements now

jurisdiction over the Premises and of any agency thereof) or asbestos-containing
materials (it being understood that Tenant shall not be obligated to remove
existing non-friable asbestos unless hereafter required pursuant to any Legal
Requirement or unless such non-friable asbestos is hereafter disturbed by
renovation, casualty or other event, in which event the non-friable asbestos
shall be removed and provided, further, that any existing non-friable asbestos

appropriate operations and maintenance program), and (iv) shall cause any
alterations of the Premises to be done in a way such that there are no Hazardous
Substances present upon the Premises which are not in compliance with
Environmental Laws or which present a danger to persons working on or visiting

         (c) To the extent required by any Environmental Law, Tenant shall
remove any Hazardous Substance whether now or hereafter existing on the Premises
and whether or not arising out of or in any manner connected with Tenant's
occupancy of the Premises during the Term. Tenant shall and hereby does agree to
defend, indemnify and hold Lender and Landlord, their officers, directors,
shareholders, partners and employees, harmless from and against any and all
causes of actions, suits, demands or judgments of any nature whatsoever, losses,
damages, penalties, expenses, fees, claims, costs (including response and
remedial costs), and liabilities, including, but not limited to, reasonable
attorneys' fees and costs of litigation, arising out of or in any manner
connected with (i) the violation of any Environmental Law with respect to the
Premises, (ii) the release, threatened release, or existence of or failure to
remove, as required by this Article 7, Hazardous Substances from the Premises,

Landlord and Lender notice of the occurrence of any of the following events: (i)
the failure of the Premises to comply with any Environmental Law in any manner

situated in a commercially reasonably manner and in compliance with Legal
Requirements; (ii) the issuance to the Tenant or any tenant of space in the
Premises or any assignee or licensee of the Tenant of any notice, request for
information, complaint or order of violation or noncompliance or liability of
any nature whatsoever with regard to the Premises or the use thereof with
respect to Environmental Laws; (iii) any notice of a pending or threatened
investigation as to whether the Tenant's (or its "subtenants" or "assignees")
operations on the Premises are in compliance with or may lead to liability to
the Tenant under, any Environmental Law; or (iv) the occurrence of an event or
the existence of a situation which is likely to result in a violation of
Environmental Laws at the Premises or which is likely to result in the Tenant
being liable to the Landlord by virtue of the indemnity given by the Tenant
pursuant to Section 7.1(c).

7.3 Survival. The indemnity obligations of the Tenant and the rights and
remedies of the Landlord and Lender under this Article 7 shall survive the
expiration or earlier termination of this Lease.

                                   ARTICLE 8.

8.1 Holdover. If the Tenant shall continue to occupy the Premises after the
expiration or earlier termination of this Lease, then Tenant shall be deemed to
be a holdover tenant, the tenancy of which shall be from month to month upon the
same provisions and conditions set forth in this Lease, except that Basic Rent
for the holdover period shall be an amount equal to 150% of the Basic Rent in
effect immediately prior to the holdover period. This Article 8 does not amount
to a waiver of the Landlord's right of reentry or any other right granted under
Article 5 and shall not constitute a consent to any holdover by Tenant.

                                   ARTICLE 9.

9.1 No Merger. There shall be no merger of this Lease or of the leasehold estate
hereby created with the fee estate in the Premises by reason of the fact that
the same person acquires or holds, directly or indirectly, this Lease or the
leasehold estate hereby created or any interest herein or in such leasehold
estate as well as the fee estate in the Premises or any interest in such fee
estate.

9.2 Surrender. Upon the expiration or earlier termination of this Lease, Tenant
shall surrender the Premises to Landlord in good repair and condition. Tenant
shall remove from the Premises on or prior to such expiration or termination
all property situated thereon which is not owned by Landlord and shall repair
any damage caused by such removal. Property not so removed shall become the
property of Landlord, and Landlord may cause such property to be removed from
the Premises and disposed of, but the cost of any such removal and disposition
and of repairing any damage caused by such removal shall be borne by Tenant.
Landlord shall credit the net proceeds of a disposition of such property
actually realized by Landlord against such costs to be borne by Tenant, provided
that the Lease termination giving rise to such disposition was not caused by an
Event of Default hereunder. The provisions of this Section shall survive the
termination or expiration of this Lease.

9.3 Separability; Binding Effect. Each provision hereof shall be separate and
independent and the breach of any provision by Landlord shall not discharge or
relieve Tenant from any of its obligations hereunder. If any provision hereof is
held invalid or unenforceable, the remaining provisions hereof shall not be
affected thereby. All provisions contained in this Lease shall be binding upon,
inure to the benefit of, and be enforceable by, the successors and assigns of
Landlord to the same extent as if each such successor and assign were named as a
party hereto. All provisions contained in this Lease shall be binding upon the
successors and assigns of Tenant and shall inure to the benefit of and be
enforceable by the permitted successors

                                       36
<PAGE>
and assigns of Tenant in each case to the same extent as if each such successor
and assign were named as a party hereto.

9.4 Counterparts. This Lease may be executed in two or more counterparts, and
all such counterparts shall be deemed to constitute but one and the same
instrument.

9.5 Recording of Lease. Tenant will execute, acknowledge, deliver and cause to
be recorded or filed in the manner and place required by any present or future
law a memorandum of this Lease. Tenant shall be responsible for all costs and
expenses in connection with the recording of this Lease or a memorandum hereof.

9.6 No Brokers. Each of the Landlord and the Tenant represents and warrants to
the other that it has not dealt with any broker (other than CB Richard Ellis,
Inc. who will be compensated by Landlord) in connection with the purchase and
leasing of the Premises, and indemnifies the other against the claims of brokers
claiming through it.

9.7 Governing Law. The terms and provisions of this Lease shall be governed by
the laws of the state in which the Premises are located.

9.8 Waiver of Jury Trial. LANDLORD AND TENANT HEREBY IRREVOCABLY AND
UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING
TO THIS LEASE.

9.9 Conveyance by Landlord. The word "Landlord" as used in this Lease means
only the owner for the time being of the Premises, so that, if there is a
transfer of an owner's interest, the transferor shall be and hereby is entirely
freed and relieved of all covenants and obligations of the Landlord hereunder,
except any obligations which accrued prior to the date of transfer, and it shall
be deemed and construed, without further agreement between the parties or
between the parties and the transferee of the Premises, that the transferee has
assumed and has agreed to carry out any and all of the Landlord's covenants and
obligation hereunder from and after the date of transfer.

9.10 Relationship of the Parties. Nothing contained in this Lease shall be
construed in any manner to create any relationship between the Landlord and the
Tenant other than the relationship of landlord and tenant. Without limitation,
the Landlord and the Tenant shall not be considered partners or co-venturers
for any purpose on account of this Lease.

9.11 Representation by Counsel. The Tenant and the Landlord each acknowledge
that it was represented by counsel in connection with the negotiation and
execution of this Lease. This Lease shall not be construed as if it had been
prepared by one of the parties, but rather as if all parties have prepared it.

9.12 Access to Premises. The Tenant will permit the Landlord, any Lender or
prospective Lender or purchaser, and their duly authorized representatives to

                                       37
<PAGE>
enter upon the Premises and to inspect the same at any and all reasonable times,
upon one Business Day advance written notice, and at any time in the case of an
emergency without the giving of notice, and for any purpose reasonably related
to the rights of the Landlord and any Lender under this Lease. Landlord and
Lender shall, in exercising such rights of access, cause no unreasonable
interference with Tenant's business or Tenant's guests. Notwithstanding the
foregoing, Landlord agrees that it will not exercise the foregoing right of
access for the Premises more than once in any calendar year except (a) during
such time as an Event of Default has occurred and is continuing, or (b) in the
event of a sale, financing, refinancing or securitization of any Indenture
relating to the Premises, or (c) if Landlord has reasonable grounds to believe
that the Premises are in violation of Legal Requirements (including
Environmental Laws) or that the Premises are not being maintained in accordance
with the requirements of this Lease or (d) as otherwise expressly provided in
this Lease.

9.13 Showing. During the last 360 days of the Term (or at any time when Tenant
is in default), Landlord, subject to the rights of any subtenant not affiliated
with Tenant, may show the Premises to prospective tenants or purchasers at such
reasonable times during normal business hours as Landlord may select upon one
Business Days prior notice to Tenant, provided that Landlord does not materially
interfere with Tenant's normal business operations.

9.14 True Lease. This Lease is intended as, and shall constitute, an agreement
of lease, and nothing herein shall be construed as conveying to the Tenant any
right, title or interest in or to the Premises nor to any remainder or
reversionary estates in the Premises held by any Person, except, in each
instance, as a tenant. Under no circumstances shall this Lease be regarded as an
assignment of all of Landlord's interests in and to the Premises; instead
Landlord and Tenant shall have the relationship between them of landlord and
tenant, pursuant to the provisions of this Lease.

9.15 Landlord's Consent and Standards.

         (a) Whenever Landlord or Lender is allowed or required to give its
consent or approval of any matter under this Lease or to deliver any estoppel or
other instrument, Tenant's sole remedy for such failure to give such consent or
approval or deliver such instrument in accordance with the applicable provision
of this Lease shall be to compel such approval or delivery. In no event and
under no circumstance shall Tenant be entitled to any monetary damages for such
failure or to terminate or otherwise modify this Lease. However, if Tenant shall
bring such an action to compel consent, approval or delivery, the prevailing
party in such action shall be entitled to reimbursement for its reasonable
attorneys' fees; provided, however, that with respect to any attorneys' fees to
be reimbursed by Landlord, such fees and Tenant's right to recover the same
shall be junior and subordinate to an Indenture, and in no event shall Tenant be
entitled to offset any amounts due under this Lease to recover such fees.

                                       38
<PAGE>
         (b) Under no circumstance shall Landlord be deemed to have acted
negligently, grossly negligently or willfully merely by Landlord's ownership of
the Premises, and in no event shall any occurrence relating to the Premises,
whether negligent, grossly negligent or willful, be imputed to Landlord by
reason of Landlord's interest in the Premises, it being understood that all
obligations with respect to the Premises are the responsibility of Tenant under
this Lease. In order to have acted negligently, grossly negligently or
willfully, Landlord must have committed an affirmative act.

9.16 Quiet Enjoyment. Landlord covenants that, so long as Tenant shall
faithfully perform the agreements, terms, and covenants and conditions hereof,
Tenant shall and may peaceably and quietly have, hold and enjoy the Premises for
the term hereby granted without molestation or disturbance by or from Landlord.

9.17 Force Majeure. The term "Force Majeure", as used in this Lease, shall mean
delays caused by acts of God, strikes and other similar events beyond the
control of Tenant. However, the duration of any delay excused by Force Majeure
shall be limited to the actual amount of time caused by the event giving rise to
the Force Majeure. In addition, no performance by Tenant under this Lease shall
be excused by Force Majeure unless the requirement for performance set forth in
this Lease specifically states that it is subject to Force Majeure.

         IN WITNESS WHEREOF, the parties hereto have caused this Lease to be
executed as of the date first above written.

                                   SCHEDULE F
           DETERMINING FAIR MARKET VALUE FOR REJECTABLE PURCHASE OFFER

If Tenant is required to make a Rejectable Purchase offer under this Lease,
Tenant shall deliver to Landlord at the time of making such Rejectable Purchase
offer, an appraisal of the Premises by an Appraiser. The appraisal shall
calculate the fair market value ("Fair Market Value") as of the date which is
immediately prior to such Condemnation and shall assume that the Premises are
subject to the Lease (and in the condition required to be maintained pursuant to
this Lease), the Lease is in full force and effect, and no condemnation is
pending or threatened.

If Landlord is in agreement with such appraisal, such appraisal shall fix the
Fair Market Value. If Landlord gives Tenant written notice of its disapproval of
the appraisal (to be delivered by Landlord within the twenty (20) days of its
receipt of the appraisal, Fair Market Value shall be determined in accordance
with the following procedure:

Within thirty (30) days after the delivery of notice by Landlord disapproving
Tenant's appraisal, Landlord shall submit to Tenant an appraisal of the
Premises, prepared by an Appraiser; in addition, Landlord's Appraiser and
Tenant's Appraiser shall jointly, within fifteen (15) days after delivery of
notice by Landlord disapproving Tenant's appraisal, choose a third Appraiser who
shall, within thirty days after appointment, choose one of the two appraised
values as the Fair Market Value. The Fair Market Value of the Premises, as
determined by the foregoing procedure, shall be binding upon both Tenant and
Landlord. The fees and expenses of the Appraisers shall be borne by Tenant.

 The Appraisers shall not, in making their appraisal of the Premises, attribute
 any value to any of Tenant's Personal Property.

                                 LEASE AGREEMENT

      THIS LEASE AGREEMENT, dated as of December ____, 2000 (this "Lease"), is
made and entered into among CPSIEE, LLC, a Delaware limited liability company,
LLC, a Delaware limited liability company, (together with its respective
successors and assigns, herein called "Landlord", having an address at c/o CB
Richard Ellis Investors, L.L.C., 865 S. Figueroa Street, Suite 3500, Los
Angeles, California 90017-2543, and Southwest Medical Associates, Inc., a Nevada
corporation (together with its successors and assigns, herein called "Tenant"),
having an address at 2716 N. Tenaya Way, Las Vegas, Nevada 89126.

                                   ARTICLE 1.

1.1 Lease of Premises; Title and Condition.

      (a) In consideration of the rents and covenants herein stipulated to be
paid and performed by Tenant and upon the terms and conditions herein specified,
Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the
premises (the "Premises") consisting of:

            (i) that certain parcel of land more particularly described on
Schedule A attached hereto and made a part hereof, together with all of the
Landlord's right, title and interest, if any, in and to (1) all easements,
rights-of-way, appurtenances, and other rights and benefits belonging to the
parcel of land, and (2) all public or private streets, roads, avenues, alleys,
or passageways, open or proposed, on or abutting each of the parcels of land,
and any award made or to be made in lieu thereof (collectively, the "Land"); and

            (ii) all buildings located on the Land, together with all plumbing,
electrical, ventilating, heating, cooling, lighting and other utility systems,
equipment, ducts and pipes attached to or comprising a part thereof (the
"Improvements"); and

            (iii) all machinery and equipment owned by Landlord and located on,
attached, affixed or incorporated into the Land and Improvements including,
without limitation, all floor coverings, lighting, appliances, telephone wiring
and jacks, and other miscellaneous fixtures and equipment now or hereafter
located on the Land and used in the operation of the Improvements (the
"Equipment").

Notwithstanding anything to the contrary in the foregoing, the Premises and the
Equipment do not include Tenant's personal property, Tenant's or any sublessee's
tradenames or trademarks or the right to use the same (collectively, the
"Tenant's Personal Property "), which shall remain the property of Tenant, or
its affiliates, as the case may be.

The Premises are leased to Tenant in their present condition without
representation or warranty by Landlord and subject to the rights of parties

                                       1
<PAGE>
in possession, to the existing state of title and any state of facts which an
accurate survey or physical inspection might reveal, to all applicable Legal
Requirements (as hereinafter defined) now or hereafter in effect and subject to
those matters listed in Schedule B attached hereto and made a part hereof (the
"Permitted Exceptions").

      (b) Tenant has examined the Premises and title to the Premises and has
found all of the same satisfactory for all purposes. Tenant acknowledges that
Tenant is fully familiar with the physical condition of the Premises and that
the Landlord makes no representation or warranty, express or implied, with
respect to same. THE LEASE OF THE PREMISES IS ON AN "AS IS" BASIS, IT BEING
AGREED THAT TENANT WILL LEASE THE PREMISES IN THEIR PRESENT CONDITION, WITH ALL
FAULTS. LORD HEREBY DISCLAIMS ANY AND ALL EXPRESS OR IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE RELATIVE TO THE PREMISES
OR ANY COMPONENT PART THEREOF. Tenant acknowledges and agrees that no
representations or warranties have been made by Landlord, or by any person, firm
or agent acting or purporting to act on behalf of Landlord, as to (i) the
presence or absence on or in the Premises of any particular materials or
substances (including, without limitation, asbestos, hydrocarbons or hazardous
or toxic substances), (ii) the condition or repair of the Premises or any
portion thereof, (iii) the value, expense of operation or income potential of
the Premises, (iv) the accuracy or completeness of any title, survey, structural
reports, environmental audits or other information provided to Tenant by any
third party contractor relative to the Premises (regardless of whether the same
were retained or paid for by Landlord), or (v) any other fact or condition which
has or might affect the Premises or the condition, repair, value, expense of
operation or income potential thereof. Tenant represents that the officers of
Tenant are knowledgeable and experienced in the leasing of properties comparable
to the Premises and agrees that Tenant will be relying solely on Tenant's
inspections of the Premises in leasing the Premises. THE PROVISIONS OF THIS
PARAGRAPH HAVE BEEN NEGOTIATED AND ARE INTENDED TO BE A COMPLETE EXCLUSION AND
NEGATION BY THE LORD OF, AND THE LORD DOES HEREBY DISCLAIM, ANY AND ALL
WARRANTIES BY THE LORD, EXPRESS OR IMPLIED, WITH RESPECT TO THE PREMISES OR ANY
PORTION THEREOF, WHETHER ARISING PURSUANT TO THE UNIFORM COMMERCIAL CODE OR ANY
OTHER LAW NOW OR HEREAFTER IN EFFECT OR OTHERWISE, AND TENANT HEREBY
ACKNOWLEDGES AND ACCEPTS SUCH EXCLUSION, NEGATION AND DISCLAIMER.

1.2 Use. Tenant may use the Premises for any lawful purpose, but may not change
the current use if such change would materially increase the risk of violating
an Environmental Law. Landlord and its agents and designees may enter upon and
examine the Premises at reasonable times, subject to the provisions of Section
9.12. In no event shall the Premises or any portion thereof be used for any
purpose which violates any of the provisions of this Lease, including but not
limited to, provisions with respect to compliance with Legal Requirements (as
defined in Section 2.2 (b) hereof) and other recorded covenants, restrictions or
agreements which are applicable to the Premises. Tenant shall not use, occupy or
permit the Premises to be used or occupied, nor do or permit anything to be
done in or on the Premises in a manner which would (i) violate any certificate
of occupancy or equivalent certificate affecting the Premises or violate any
zoning or other Law,

                                       2
<PAGE>
ordinance or regulation, (ii) make void or voidable any insurance then in effect
with respect to the Premises, (iii) materially and adversely affect in any
manner the ability of Tenant to obtain fire and other insurance which Tenant is
required to furnish hereunder, (iv) cause any injury or damage to the
Improvements which is not repaired in accordance with the provisions of this
Lease, (v) violate any provision of an applicable ground lease, or (vi)
constitute a public or private nuisance or waste. Tenant shall not conduct its
business operation in the Premises unless and until (and only during such time
as) all necessary certificates of occupancy, permits, licenses and consents from
any or all appropriate governmental authorities have been obtained by Tenant, at
Tenant's sole cost and expense, and are in full force and effect.

1.3 Terms.

      The Premises are leased for a primary term (the "Primary Term") covering
the period shown on Schedule C attached hereto to the right of the words
"Primary Term", and, at Tenant's option, for up to five (5) five year
consecutive additional terms (the "Extended Terms"), unless and until the term
of this Lease shall expire or be terminated pursuant to any provision hereof.
The Primary Term and each Extended Term (collectively, the "Term") shall
commence and expire on the dates set forth in Schedule C attached hereto and
made a part hereof. "Commencement Date" shall refer to the commencement date of
the Primary Term.

So long as no Event of Default shall have occurred and be continuing, Tenant may
elect to exercise its option to extend the term of this Lease for an Extended
Term by giving written notice thereof to Landlord not later than (i) 365 days
prior to the expiration of the Primary Term, with respect to the first Extended
Term, and (ii) 365 days prior to the expiration of the then current Term, with
respect to any other Term. If Landlord and Tenant cannot agree in writing on the
Fair Market Rent of the Premises, Tenant's notice of election to extend the term
of this Lease for the first Extended Term shall be accompanied by an appraisal
of the then Fair Market Rent of the Premises prepared by an Appraiser.
"Appraiser" shall mean a member of the Appraisal Institute, in good standing,
holding the MAI designation and who is licensed in the State of Nevada (or
associated with a nationally recognized firm if permitted under applicable law)
and who is familiar with the Nevada market and single-tenant properties with
comparable or similar uses. Subject to Tenant's right to rescind its notice to
extend the Term as provided in Section 1.4(a) hereof, such notice shall
automatically extend the term of this Lease for the Extended Term selected,
without further writing; provided, however, either party, upon request of the
other, shall execute and acknowledge, in form suitable for recording, an
instrument confirming any such extension. Each Extended Term shall be upon the
same terms as provided in this Lease for the Primary Term, except as otherwise
stated herein. Tenant shall not be entitled to extend the term of this Lease for
any Extended Term unless Tenant shall have extended the term of this Lease for
the preceding Extended Term, if any.

1.4 Rent.

                                       3
<PAGE>
      (a) Tenant shall pay to Landlord (or to such other party as Landlord may
from time to time specify in writing at least ten days before Tenant makes
payment) by federal funds wire transfer in immediately available funds (in U.S.
Dollars) as basic rent for the Premises during the Primary Term the amounts set
forth in Schedule D attached hereto and made a part hereof (the "Basic Rent") on
the dates set forth therein (or if any such date falls on a day which is not a
Business Day (defined as any day other than a Saturday or Sunday or other day on
which the banks in New York, New York are authorized or required to be closed),
the next succeeding Business Day, the " Payment Dates"), to such account as
Landlord from time to time may designate.

      Tenant shall pay Basic Rent for the Extended Terms, if any, in the same
manner as required for the Primary Term, monthly in advance beginning on the
15th day of the first month of the First Extended Term and on the 15th day of
each month thereafter for the remainder of the Term. The Basic Rent for each
month of the first year of the first Extended Term shall be equal to the greater
of (i) 101.5% of the Basic Rent for the last month of the Primary Term and (ii)
the Fair Market Rent for the Premises as of the commencement of the first
Extended Term. The annual Basic Rent for the second year of the first Extended
Term and for each year thereafter for the remainder of the Term shall be
increased by 1.5% annually, but 1/12 of such annual Basic Rent shall be
payable each month in advance.

      The term "Fair Market Rent" shall mean the rental value of the Premises
under the terms and conditions of this Lease and determined at the time in
question. If Landlord and Tenant agree upon the Fair Market Rent of the Premises
at the time the notice to extend is given, the Fair Market Rent shall be as
agreed. If Landlord is in agreement with the appraisal delivered by Tenant
pursuant to Section 1.3 above, such appraisal, if any, shall determine the Fair
Market Rent. If Landlord gives Tenant written notice of its disapproval (the
"Disapproval Notice") of Tenant's appraisal (to be delivered by Landlord within
30 days after Landlord's receipt of Tenant's appraisal) Fair Market Rent shall
be determined in accordance with the following procedure:

      Within thirty days after the delivery of the Disapproval Notice, Landlord
shall submit to Tenant an appraisal of Fair Market Rent of the Premises,
prepared by an Appraiser. If the higher of the two appraised values determined
by the Appraisers for Landlord and Tenant is less than or equal to 105% of the
lower appraised value, then Fair Market Rent shall be set at the average of the
two appraised values. If the two appraised values differ by more than five
percent, then Landlord's appraiser and Tenant's appraiser shall jointly, within
thirty days after delivery of the Disapproval Notice, choose a third Appraiser
who shall, within fifteen days after receipt of both Landlord's and Tenant's
appraisals, choose one of the two appraised values as the Fair Market Rent. The
Fair Market Rent, as determined by the foregoing arbitration procedure, shall be
binding upon both Tenant and Landlord. If Fair Market Rent determined in
accordance with the procedure set forth in this paragraph exceeds 105% of the
Fair Market Rent given by the Tenant's Appraiser, the Tenant shall have the
right to rescind its notice to extend

                                       4
<PAGE>
the term of this Lease within 15 days after such determination of Fair Market
Rent by giving Landlord written notice of such rescission. Whether or not Tenant
rescinds its notice to extend the term of this Lease, the fees and expenses of
the Appraisers shall be borne by Tenant.

      (b) All taxes, costs, expenses and amounts which Tenant is required to pay
pursuant to this Lease (other than Basic Rent), together with every fine,
penalty, interest and cost which may be added for non-payment or late payment
thereof, shall constitute additional rent ("Additional Rent"). If Tenant shall
fail to pay any such Additional Rent or any other sum due hereunder when the
same shall become due, Landlord shall have all rights, powers and remedies with
respect thereto as are provided herein or by law in the case of non-payment of
any Basic Rent and shall, except as expressly provided herein, have the right to
pay the same on behalf of Tenant. Tenant shall pay to Landlord interest, at a
rate (the "Default Rate") equal to the lesser of fifteen percent per annum and
the maximum rate permitted by law, on all overdue Basic Rent from the due date
thereof until paid and on all overdue Additional Rent and all other sums due
hereunder, from the end of the third Business Day after delivery of written
notice of default to Tenant. In addition, if Tenant fails to make any payment of
Basic Rent, Additional Rent or other sums payable hereunder to Landlord within
three Business Days after delivery of written notice to Tenant that any such
Basic Rent, Additional Rent or other sum payable hereunder has not been paid on
the due date thereof, Tenant shall pay a late charge equal to four percent (4%)
of the amount past due. Tenant shall perform all its obligations under this
Lease at its sole cost and expense, and shall pay all Basic Rent, Additional
Rent and any other sum due hereunder when due and payable, without offset,
notice or demand.

                                   ARTICLE 2.

2.1 Net Lease.

      (a) This Lease is a net lease and, any present or future law to the
contrary notwithstanding, shall not terminate except as otherwise expressly
provided herein, nor shall Tenant be entitled to any abatement, reduction,
diminution, set-off, counterclaim, defense (except for the defense that the
performance or payment has been made) or deduction with respect to any Basic
Rent, Additional Rent or other sums payable hereunder, nor shall Tenant be
excused from the performance of its obligations hereunder, by reason of: any
damage to or destruction of the Premises or any portion thereof; any defect in
the condition, design, operation or fitness for use of the Premises or any
portion thereof; any taking of the Premises or any part thereof by condemnation
or otherwise; any prohibition, limitation, interruption, cessation, restriction
or prevention of Tenant's use, occupancy or enjoyment of the Premises, or any
interference with such use, occupancy or enjoyment by any person; any eviction
by paramount title or otherwise; any default by Landlord hereunder or under any
other agreement; the impossibility or illegality of performance by Landlord,
Tenant or both; any action of any

                                       5
<PAGE>
governmental authority (including, without limitation, changes in Legal
Requirements); construction on or renovation of the Premises; or any failure in
the Premises to comply with applicable laws, Legal Requirements, or any other
cause whether similar or dissimilar to the foregoing. All costs, expenses and
obligations of every kind and nature whatsoever relating to the Premises and the
appurtenances thereto and the use and occupancy thereof which may arise or
become due and payable with respect to the period which ends on the expiration
or earlier termination of the Term in accordance with the provisions hereof
(whether or not the same shall become payable during the Term or thereafter)
shall be paid by Tenant. It is the purpose and intention of the parties to this
Lease that the Basic Rent, Additional Rent and other sums payable to Landlord
hereunder shall be absolutely net to Landlord and that this Lease shall yield,
net to Landlord, the Basic Rent, Additional Rent, and other sums payable to
Landlord as provided in this Lease. The parties intend that the obligations of
Tenant hereunder shall be separate and independent covenants and agreements and
shall continue unaffected unless such obligations shall have been modified or
terminated pursuant to an express provision of this Lease.

      (b) Tenant shall remain obligated under this Lease in accordance with its
terms and shall not take any action to terminate, rescind or avoid this Lease,
notwithstanding any bankruptcy, insolvency, reorganization, liquidation,
dissolution or other proceeding affecting Landlord or any action with respect to
this Lease which may be taken by any trustee, receiver or liquidator or by any
court.

      (c) Tenant waives all rights to surrender this Lease, or to any abatement
or deferment of Basic Rent, Additional Rent or other sums payable hereunder.
Tenant waives all rights to terminate this Lease, except in the case of a Total
Condemnation, Major Condemnation or Major Casualty in accordance with the
provisions of Article 3.

2.2 Taxes and Assessments; Compliance with Law.

      (a) Subject to Tenant's right to contest pursuant to Section 2.6 of this
Lease, Tenant shall pay, prior to delinquency, all "Impositions", which are
defined as: (i) all taxes (including, without limitation, those described in
(iii) below), assessments (including, without limitation, all assessments for
public improvements or benefits, whether or not commenced or completed prior to
the date hereof and whether or not commenced or completed within the term of
this Lease), excises, levies, fees (including, without limitation, license,
permit, inspection, authorization and similar fees), water and sewer rents and
charges, and all other governmental charges, general and special, ordinary and
extraordinary, foreseen and unforeseen, and any interest and penalties thereon
which are, at any time prior to or during the Primary Term or any Extended Term
hereof, imposed or levied upon or assessed against or which arise with respect
to (A) the Premises, (B) any Basic Rent, Additional Rent or other sums payable
hereunder, (C) this Lease or the leasehold estate hereby created or (D) the
operation, possession or use of the Premises; (ii) all gross receipts or similar
taxes (i.e., taxes based upon gross income which fail to take into account
deductions with respect to depreciation,

                                       6
<PAGE>
interest, taxes or ordinary and necessary business expenses, in each case
relating to the Premises) imposed or levied upon, assessed against or measured
by any Basic Rent, Additional Rent or other sums payable hereunder; (iii) all
sales (including those imposed on lease rentals), value added, ad valorem, gross
receipts, use and similar taxes at any time levied, assessed or payable on
account of the acquisition, ownership, leasing, operation, possession or use of
the Premises; (iv) all transfer, recording, stamp and real property gain taxes
incurred upon the sale or transfer, or other disposition of the Premises or any
interest therein to Tenant or the foreclosure of the Premises, (v) all offers,
claims and demands of mechanics, laborers, materialmen and others which, if
unpaid, might create a lien on the Premises, (vi) all charges of utilities,
communications and similar services serving the Premises, and (vii) any other
tax relating to the Premises resulting from any law enacted or adopted or
amended after the date of this Lease imposed on Landlord pursuant to any deed of
trust or mortgage creating a first mortgage lien on the Premises ("Indenture").
Notwithstanding the above, Tenant shall not be required to pay any franchise,
estate, inheritance, transfer, net income or similar tax of Landlord (other than
any tax referred to in clause (ii) above) unless such tax is imposed, levied or
assessed in substitution for any other tax, assessment, charge or levy which
Tenant is required to pay pursuant to this Section 2.2 (a). Subject to Tenant's
right to contest pursuant to Section 2.6 of this Lease, Tenant will furnish to
Landlord, within 30 days after the due date thereof, proof of payment of all
Impositions. If any such Imposition may legally be paid in installments, Tenant
may pay such Imposition in installments; in such event, Tenant shall be liable
only for installments that become due and payable during the Term hereof.

      (b) Tenant shall comply with and cause the Premises to comply with and
shall assume all obligations and liabilities with respect to (i) all laws,
ordinances and regulations, and other governmental rules, orders and
determinations presently in effect or hereafter enacted, made or issued, both
foreseen and unforeseen and ordinary and extraordinary applicable to the
Premises or the ownership, operation, use or possession thereof and (ii) all
contracts (including, but not limited to, insurance policies (including, without
limitation, to the extent necessary to prevent cancellation thereof and to
insure full payment of any claims made under such policies)), covenants,
conditions and restrictions now or hereafter applicable to the Premises or the
ownership, operation, use or possession thereof (collectively, "Legal
Requirements"), including but not limited to all such Legal Requirements,
contracts, agreements, covenants, conditions and restrictions which require
structural, unforeseen or extraordinary changes. Notwithstanding the foregoing,
Legal Requirements shall not include any contracts, covenants, conditions or
restrictions applicable to the Premises which are hereafter voluntarily entered
into by Landlord without the consent or approval of Tenant (which approval shall
not be unreasonably withheld or delayed), unless Landlord is required to enter
into such contract, covenant, condition or restriction by any governmental or
quasi-governmental entity. Tenant's failure to comply with any such contract,
covenant, condition or restriction required by any governmental or
quasi-governmental entity to be

                                       7

entered into by Landlord shall not constitute a default by Tenant hereunder
prior to Tenant's receipt of notice or knowledge thereof.

2.3 Liens. Subject to Tenant's right to contest pursuant to Section 2.6 of this
Lease, Tenant will act promptly to remove and discharge any charge, lien,
security interest or encumbrance upon the Premises or any Basic Rent, Additional
Rent or other sums payable hereunder which arise for any reason, including all
liens which arise out of the possession, use, occupancy, construction, repair or
rebuilding of the Premises or by reason of labor or materials furnished or
claimed to have been furnished to Tenant or for the Premises, but not including
(i) the Permitted Exceptions, and (ii) any mortgage, charge, lien, security
interest or encumbrance created by Landlord without the consent of Tenant (it
being agreed that an Indenture for purposes of this sentence will be deemed to
have been created without the consent of Tenant). Nothing contained in this
Lease shall be construed as constituting the consent or request of Landlord,
express or implied, to or for the performance by any contractor, laborer,
materialman, or vendor of any labor or services or for the furnishing of any
materials for any construction, alteration, addition, repair or demolition of or
to the Premises or any part thereof which would result in any liability of the
Landlord for the payment therefor. Notice is hereby given that Landlord will not
be liable for any labor, services or materials furnished or to be furnished to
Tenant, or to anyone holding an interest in the Premises or any part thereof
through or under Tenant, and that no mechanic's or other liens for any such
labor, services or materials shall attach to or affect the interest of Landlord
in the Premises.

2.4 Indemnification.

      (a) Tenant agrees to defend, indemnify, and hold harmless Landlord and
Lender from and against any and all liabilities, losses, damages, penalties,
expenses (including reasonable attorneys' fees and expenses), causes of action,
suits, claims, demands or judgments of any nature whatsoever, howsoever caused,
arising from the Premises and the use, occupancy, condition, design,
construction, maintenance, repair or rebuilding of the Premises, and any injury
to or death of any person or persons or any loss of or damage to any property,
real or personal, in any manner arising therefrom or occurring thereon, whether
or not Landlord or Lender has or should have knowledge or notice of the defect
or conditions, if any, causing or contributing to said injury, death, loss,
damage or other claim; but with respect to Landlord (and not as to Lender)
except to the extent that any such liability, loss, damage, penalty, expense,
cause of action, suit, claim, demand or judgment is the result of the gross
negligence of Landlord or the intentional wrongful act of Landlord. In case any
action or proceeding is brought against Landlord or the mortgagee or beneficiary
under an Indenture ("Lender") by reason of any such claim against which Tenant
has agreed to defend, indemnify, and hold harmless pursuant to the preceding
sentence, Tenant covenants upon notice from Landlord or Lender to defend
Landlord and Lender in such action, with the expenses of such defense paid by
Tenant, and Landlord will cooperate and assist in the defense of such action or
proceeding if reasonably requested by Tenant.

                                       8
<PAGE>
      (b) The obligations of Tenant under this section 2.4 shall survive the
expiration or earlier termination of this Lease.

2.5 Maintenance and Repair.

      (a) Tenant acknowledges that it has received the Premises in good order
and repair. Tenant, at its own expense, will maintain all parts of the Premises
(including all parking areas) in good repair and condition and will take all
action and will make all structural and non-structural, foreseen and unforeseen
and ordinary and extraordinary changes and repairs which may be required to keep
all parts of the Premises in good repair and condition. Landlord shall not be
required to maintain, repair or rebuild all or any part of the Premises. Tenant
waives the right to (i) require Landlord to maintain, repair or rebuild all or
any part of the Premises, or (ii) make repairs at the expense of Landlord
pursuant to any Legal Requirement, contract, covenant, condition or restriction
set forth in subsection 2.2(b)(ii), at any time in effect.

      (b) If all or any part of the Improvements shall encroach upon any
property, street or right-of-way adjoining or adjacent to the Premises, or shall
violate the agreements or conditions affecting the Premises, or any Legal
Requirements, or shall hinder, obstruct or impair any easement or right-of-way
to which the Premises are subject, then, promptly after written request of
Landlord (unless such encroachment, violation, hindrance, obstruction or
impairment is a Permitted Exception) or of any person so affected, Tenant shall,
at its expense, either (i) obtain valid and effective waivers or settlements of
all claims, liabilities and damages resulting therefrom, or (ii) make such
changes, including alteration or removal, to the Improvements and take such
other action as shall be necessary to remove or eliminate such encroachments,
violations, hindrances, obstructions or impairments, provided that, if
Landlord's consent is required for such changes pursuant to this Lease,
Landlord's consent shall have been obtained, which consent shall not be
unreasonably withheld.

2.6 Permitted Contests.

      (a) After prior written notice to Landlord and Lender, Tenant shall not be
required to (i) pay any Imposition, (ii) comply with any Legal Requirement, or
(iii) discharge or remove any lien or encumbrance so long as Tenant shall
contest, in good faith and at its expense, the existence, the amount or the
validity thereof, the amount of the damages caused thereby, or the extent of its
or Landlord's liability therefor, by appropriate proceedings which shall operate
during the pendency thereof to prevent (A) the collection of, or other
realization upon, the Imposition or lien so contested, (B) the sale, forfeiture
or loss of any of the Premises, any Basic Rent, or any Additional Rent to
satisfy the same or to pay any damages caused by the violation of any Legal
Requirement or by any such violation, (C) any interference with the use or
occupancy of any of the Premises, (D) any

                                       9
<PAGE>
interference with the payment of any Basic Rent or any Additional Rent, (E) the
cancellation of any fire or other insurance policy.

      (b) In no event shall Tenant pursue any contest with respect to any
Imposition, Legal Requirement, lien or violation, referred to above in such
manner that exposes Landlord or Lender to (i) criminal liability, penalty or
sanction, (ii) any civil liability, penalty or sanction for which Tenant has not
made provisions reasonably acceptable to Landlord and Lender or (iii) defeasance
of its interest in the Premises.

      (c) Tenant agrees that each contest shall be promptly and diligently
prosecuted to a final conclusion, except that Tenant shall have the right to
attempt to settle or compromise such contest through negotiations. Tenant shall
pay, indemnify, defend and save Lender and Landlord harmless against any and all
losses, judgments, decrees and costs (including all attorneys' fees and
expenses) in connection with any such contest and shall, promptly after the
final determination of such contest, fully pay and discharge the amounts which
shall be levied, assessed, charged or imposed therein, together with all
penalties, fines, interest and expenses thereof, and perform all acts the
performance of which shall be ordered as a result thereof. The obligations of
Tenant under this Section 2.6 (c) shall survive the expiration or earlier
termination of this Lease.

                                   ARTICLE 3.

3.1 Omitted

3.2 Condemnation and Casualty.

      (a) General Provisions. Subject to Tenant's rights to utilize or obtain
the same in accordance with Section 3.5, Tenant hereby irrevocably assigns to
Landlord any award, compensation or insurance payment to which Tenant may become
entitled by reason of Tenant's interest in the Premises (i) if the use,
occupancy or title of the Premises or any part thereof is taken, requisitioned
or sold in, by or on account of any actual or threatened eminent domain
proceeding or other action by any person having the power of eminent domain
("Condemnation") or (ii) if the Premises or any part thereof is damaged or
destroyed by fire, flood or other casualty (" Casualty ") (all awards,
compensations, and insurance payments on account of any Condemnation or Casualty
(net of any amounts applicable to Tenant's Personal Property) are hereinafter
collectively called "Compensation"). In the event of any Casualty, or in the
event of a Condemnation or threatened Condemnation, Tenant shall give prompt
written notice thereof to Landlord (which notice shall set forth Tenant's good
faith estimates of the cost of repairing or restoring any damage or destruction
caused thereby, or, if Tenant cannot reasonably estimate the anticipated cost of
restoration, Tenant shall nonetheless give Landlord prompt notice of the
occurrence of any such Casualty or Condemnation, and will diligently proceed to
obtain estimates to enable Tenant to quantify the anticipated cost of such
restoration, whereupon Tenant shall promptly notify Landlord of such good faith
estimate). Landlord

                                       10
<PAGE>
and Lender may participate in any such proceeding or action to negotiate,
prosecute and adjust any claim for any Compensation, and Landlord (or if
required by an Indenture, Lender) shall collect any such Compensation. Tenant
shall pay all reasonable costs and expenses of Tenant, Landlord and Lender in
connection with each such proceeding, action, negotiation, prosecution and
adjustment. If an Event of Default shall have occurred and be continuing or in
the case of any Condemnation or Major Casualty where Tenant is not purchasing
the Premises pursuant to Section 3.2, Landlord shall have the sole right to
conduct and control such proceedings, actions, negotiations, prosecutions and
adjustments; otherwise, Tenant shall initiate, conduct and control any such
proceeding, action, negotiation, prosecution or adjustment. All Compensation
shall be applied pursuant to the applicable provisions of Article 3, and all
such Compensation (less the reasonable costs and expenses of Landlord, Tenant
and Lender, if applicable, in collecting such Compensation), is herein called
the "Net Proceeds".

      (b) Total Condemnation. Subject to the provisions of Section 3.2(f) below,
if a Condemnation consists of a total taking of the Premises ("Total
Condemnation"), then this Lease shall terminate on the first Payment Date (the
"Lease Termination Date") which occurs not less than 120 days and not more than
150 days after receipt of the notice of such condemnation from Tenant pursuant
to Section 3.2(a).

      (c) Major Condemnation and Major Casualty. If a Condemnation is not a
Total Condemnation but it renders the Premises unsuitable for restoration for
continued use and occupancy in Tenant's business (a "Major Condemnation"), or if
a Casualty shall occur and the Restoration Cost shall exceed 50% of the
Stipulated Loss Value ("Major Casualty"), then Tenant may terminate this Lease
on the Lease Termination Date (defined below) by delivering to Landlord and if
required by an Indenture, Lender, in both cases, not later than thirty days
after such Major Condemnation or Major Casualty: (i) notice of its intention to
terminate this Lease on the first Payment Date (the "Lease Termination Date")
which occurs not less than 120 days and not more than 150 days after the
delivery of such notice (it being understood that in all events under this
Lease, the Lease Termination Date must be on a Payment Date) and (ii) a
certificate of Tenant stating that Tenant has determined in good faith in the
case of a Major Casualty, that the Restoration Cost exceeds 50% of the
Stipulated Loss Value, or in the case of a Major Condemnation that such Major
Condemnation has rendered the Premises unsuitable for restoration for continued
use and occupancy in Tenant's business, and (iii) documentation to the effect
that termination of this Lease will not be in violation of any agreement then in
effect with which Tenant is obligated to comply pursuant to this Lease. If the
Lease Termination Date occurs during the Primary Term, such notice must be
accompanied by a Rejectable Purchase Offer, as described in Section 3.2(e), in
which event the provisions of such Section shall be controlling. If Tenant does
not give notice of termination in accordance with this Section 3.2(c), then the
Lease shall remain in full force and effect and there shall be no reduction or
abatement of rent despite the Major Condemnation or Major Casualty.

                                       11
<PAGE>
      (d)   Payments; Adjustment to Basic Rent. If this Lease terminates due to
a Total Condemnation, a Major Condemnation, or a Major Casualty under Sections
3.2 (b) or (c), then: (i) any Net Proceeds (other than those specifically
relating to the Tenant's Personal Property) payable in connection with the Total
Condemnation, Major Condemnation, or a Major Casualty (or the right to receive
the same when made if payment therefor has not yet been made) shall be assigned
or paid and belong to the Landlord or if required by an Indenture, Lender
(unless the Premises are being transferred to the Tenant pursuant to Section 3.2
(f) (purchase) in which case the Net Proceeds shall be assigned or paid to
Tenant), (ii) the Tenant shall pay to the Landlord all Basic Rent accrued as of
such Lease Termination Date and all other amounts then accrued or due and
payable by the Tenant under this Lease and (iii) if an Event of Default has
occurred and is continuing, Tenant shall pay to Landlord any Make Whole Premium.
The "Make Whole Premium" shall have the meaning set forth in an Indenture, or if
not defined in an Indenture, shall mean the amount which Landlord is obligated
to pay in excess of outstanding principal and accrued interest in connection
with a prepayment or defeasance of an Indenture.

      (e)   Rejectable Purchase Offer. If during the Primary Term, there is a
Major Condemnation or a Major Casualty for which Tenant gives timely notice of
termination under Section 3.2 (c) or a Total Condemnation, Tenant shall deliver
to Landlord (in addition to the items set forth in Section 3.2 (a) and (c)
above), no later than thirty (30) days after such Total or Major Condemnation or
Major Casualty, an appraisal of the Premises in accordance with Schedule F and a
written offer ("Rejectable Purchase Offer") to purchase Landlord's interest in
the Premises on the Lease Termination Date for a price equal to the greater of
(i) the then Fair Market Value of the Premises (determined in accordance with
Schedule F) and (ii) the amount ("Stipulated Loss Value") set forth on Schedule
E. Within 90 days of the date Landlord receives the Rejectable Purchase Offer,
Landlord shall deliver written notice of its election to either accept or reject
Tenant's Rejectable Purchase Offer (with a failure to respond constituting an
acceptance of such Rejectable Purchase Offer). Any rejection by Landlord of a
Rejectable Purchase Offer shall comply with and be accomplished in accordance
with the provisions of Section 3.4.

      (f)   Acceptance of Rejectable Purchase Offer. In the event of an
acceptance or deemed acceptance of a Rejectable Purchase Offer, on the
applicable Lease Termination Date, (i) Tenant shall, by wire transfer of
immediately available funds, pay to Landlord the applicable price, together with
all Basic Rent, Additional Rent and other sums accrued or due and payable under
this Lease as of the applicable Lease Termination Date and, if an Event of
Default has occurred and is continuing, the Make Whole Premium (ii) the Net
Proceeds with respect to the Premises shall be assigned or turned over to the
Tenant upon Tenant's payment of the amounts set forth in this subsection (or if
any Net Proceeds have been applied to a Loan, such amount shall be credited
against Tenant's payment obligation under this subsection) and (iii) Landlord
shall convey to Tenant fee simple title in the Premises (to the extent any
portion has not been condemned) subject only to the Permitted Exceptions (which
shall not include my mortgage created by

                                       12
<PAGE>
Landlord) and any other liens, charges, restrictions or encumbrances created by
Tenant or any of its creditors, employees, contractors, or agents or created by
Landlord pursuant to the express terms hereof or with Tenant's consent. Tenant
shall pay (i) all charges incident to such conveyance, including, without
limitation, reasonable counsel fees, escrow fees, recording fees, title
insurance premiums, transfer taxes and all other applicable taxes (other than
any income or franchise taxes of Landlord) which may be imposed by reason of
such conveyance and the delivery of said deed or conveyance and other
instruments and (ii) all costs and expenses incurred by Landlord in connection
with a prepayment of all or any portion of the indebtedness secured by an
Indenture, including, without limitation, reasonable attorneys' fees and
expenses of Landlord and Lender and any revenue, documentary stamp or intangible
taxes. Upon the completion of Tenant's purchase of the Premises but not prior
thereto (whether or not any delay or failure in the completion of such purchase
shall be the fault of Landlord), this Lease shall terminate except with respect
to obligations and liabilities of Tenant hereunder, actual or contingent, which
have arisen on or prior to such completion of purchase.

3.3   Omitted.

3.4   Rejection of Rejectable Purchase Offer; Notice to Lender of Rejectable
Purchase Offer.

      (a)   So long as a loan which is secured by a first mortgage lien on
Landlord's interest in the Premises (hereinafter, a "Loan") is outstanding,
Tenant shall deliver to Lender, concurrently with the delivery thereof to
Landlord, a copy of any Rejectable Purchase Offer together with copies of all
items required to be delivered pursuant to Section 3.2 (a) and (c).

      (b)   If the Landlord rejects a Rejectable Purchase Offer by a timely
written notice to the Tenant, then: (i) this Lease shall terminate on the Lease
Termination Date (ii) any Net Proceeds (other than those specifically relating
to the Tenant's Personal Property) payable in connection with the Condemnation
or Casualty (or the right to receive the same when made if payment therefor has
not yet been made) shall be assigned or paid and belong to the Landlord and
(iii) the Tenant shall pay to the Landlord all Basic Rent accrued as of such
Lease Termination Date and all other amounts then accrued or due and payable by
the Tenant under this Lease. During such time as an Indenture encumbers the
Premises, no rejection of a Rejectable Purchase Offer shall be effective unless
countersigned by the Lender.

3.5   Restoration.

      (a)   Following a Condemnation or Casualty for which Tenant is not
permitted to give or, if permitted, does not give notice of its intention to
terminate this Lease as provided in Section 3.2, this Lease shall continue in
full force and effect and Tenant shall, at its expense, promptly restore the
Premises in conformity with the requirements of Sections 2.5 and 3.7 (in the
case of Condemnation, as nearly as practicable) to the condition and fair market
value thereof immediately prior to such occurrence for if the Premises

                                       13
<PAGE>
were under renovation at such time, to the planned condition and projected fair
market value thereof at the time of completion of renovation). Prior to such
restoration, Tenant shall deliver its reasonable estimate of the cost thereof,
which shall be subject to the approval of Landlord and Lender, which approval
shall not be unreasonably withheld (the cost approved by Landlord and Lender is
referred to as the "Restoration Cost").

      (b)   If the repair constitutes a Material Alteration, the Restoration
Cost must be confirmed by an architect reasonably acceptable to Landlord and
Lender (an "Architect").

      (c)   The Restoration Cost shall be paid first out of Tenant's own funds
to the extent that the Restoration Cost exceeds the Net Proceeds payable in
connection with such occurrence. To the extent that an Indenture requires that
Tenant or Landlord deliver its portion of the Restoration Costs to Lender (or
other security acceptable to Lender), Tenant shall deliver the same to Lender.
In addition, in such event the Restoration Cost shall be disbursed in accordance
with the procedure set forth in subsection (e) of this Section below. If the Net
Proceeds relate to a Casualty which is not a Major Casualty and no Event of
Default shall exist at the time of the Casualty or at the time of disbursement
of Net Proceeds, then any Net Proceeds remaining after final payment has been
made for such work and after Tenant has been reimbursed for any portions it
contributed to the Restoration Cost shall be retained by Tenant so long as the
Premises are restored to the condition and market value thereof immediately
prior to the Casualty. If the Net Proceeds relate to a Major Casualty or if an
Event of Default has occurred and is continuing, Lender may apply any Net
Proceeds towards payment of an Indenture, which payment shall not relieve Tenant
of any of its obligations hereunder. If the Net Proceeds relate to a
Condemnation other than a Total or Major Condemnation, no adjustment shall be
made in the Basic Rent and the Net Proceeds remaining after final payment for
the work and after Tenant has been reimbursed for any portions it contributed to
the Restoration Cost shall be paid as follows: (i) to Lender until the
outstanding balance of a Loan allocable to the Premises has been paid in full
(ii) from any remaining Net Proceeds, the amount allocable to the loss of use of
the Premises during the remainder of the Primary Term (or if the Condemnation
occurs during an Extended Term, then the Net Proceeds allocable to loss of use
of the Premises during the remainder of the then current Extended Term) shall be
retained by Tenant, (iii) any balance shall be retained by Landlord. In the
event of any temporary Condemnation, this Lease shall remain in full force and
effect and the Net Proceeds shall be delivered to Landlord or, if required by an
Indenture, Lender, to be applied towards the payment of Basic Rent as the same
becomes due (with any balance delivered to Tenant and any deficiency payable by
Tenant); provided, however, that such portion of the Net Proceeds allocable to
the period after the expiration or termination of the Primary Term (or if the
Condemnation occurs during an Extended Term, then after the expiration of the
then current Extended Term) shall be paid to Landlord, or if required by an
Indenture, Lender. If the cost of any rebuilding, replacement or repair required
to be made by Tenant pursuant to this Section 3.5 shall exceed the amount of
such Net Proceeds, the deficiency shall be paid by Tenant. Tenant shall not be
entitled to

                                       14
<PAGE>
disbursements of the Net Proceeds if an Event of Default has occurred and is
continuing.

      (d)   The Basic Rent and the Additional Rent payable under the provisions
of this Lease shall not be affected, altered or reduced by any Casualty or
Condemnation (except as specifically set forth in this Article with respect to a
termination of the Lease upon payment of the amounts required therein). Tenant's
obligation to continue to pay Basic Rent and Additional Rent shall continue
notwithstanding any such Condemnation or Casualty.

      (e)   If the Restoration Costs are required to be held by Landlord or
Lender pursuant to this Lease, then, as long as an Indenture is outstanding,
Landlord hereby directs that such Net Proceeds shall be held by Lender and shall
be paid out from time to time to Tenant as the work progresses (less any cost to
Lender or Landlord of recovering and paying out such proceeds, including,
without limitation, reasonable attorneys', trustees' or escrow fees relating
thereto and costs allocable to inspecting the work and the plans and
specifications therefor), subject to each of the following conditions:

            (i)   At the time of any disbursement, no Event of Default shall
exist and no mechanics' or materialmen's liens shall have been filed and remain
undischarged or unbonded.

            (ii)  Disbursements shall be made from time to time in an amount not
exceeding the hard and soft cost of the work and costs incurred since the last
disbursement upon receipt of (1) satisfactory evidence, including Architect's
certificates of the stage of completion, of the estimated cost of completion and
of performance of the work to date in a good and workmanlike manner in
accordance with the contracts, plans and specifications, (2) partial releases of
liens, and (3) other reasonable evidence of cost and payment so that Landlord
can verify that the amounts disbursed from time to time are represented by work
that is completed in place or delivered to the site and free and clear of
mechanic's lien claims.

            (iii) Each request for disbursement shall be accompanied by a
certificate of Tenant describing the work, materials or other costs or expenses,
for which payment is requested, stating the cost incurred in connection
therewith and stating that Tenant has not previously received payment for such
work or expense and the certificate to be delivered by Tenant upon completion of
the work shall, in addition, state that the work has been substantially
completed and complies with the applicable requirements of this Lease.

            (iv)  No disbursement made prior to final completion of any item of
work (in accordance with Section 3.7 (a)(v)) shall cause the aggregate amount
disbursed with respect to such item of work to exceed 90% of the value of the
portion of such item of work which has been completed if, at the time of such
disbursement, (x) an Event of Default has occurred and is continuing, or (y)
neither Tenant nor Guarantor has an Investment Grade Rating. As used

                                       15
<PAGE>
herein "Investment Grade Rating" shall mean a long term unsecured debt rating of
BBB or better by Fitch IBCA, Inc., or any successor thereto.

            (v)   Net Proceeds held by Landlord or Lender in accordance with
this Section shall be held in a separate federally insured interest bearing
account. Any interest earned on the Net Proceeds shall be a part of the Net
Proceeds, and shall be disbursed in accordance with this Lease.

      (f)   Notwithstanding any other provision of this Section, if either
Tenant or a Guarantor is then currently maintaining an Investment Grade Rating
and in Tenant's reasonable judgment the cost of the Work (as hereinafter
defined) is less than $500,000, such Work can be completed in less than one
hundred twenty (120) days (subject to Force Majeure) and no Event of Default has
occurred and is continuing and if allowed pursuant to the provisions of an
Indenture, then Landlord, upon request by Tenant, shall permit Tenant to apply
for and receive the Net Proceeds directly from the insurer or payor thereof (and
Landlord shall advise such insurer or payor and Lender to pay over such Net
Proceeds directly to Tenant), provided that Tenant shall promptly and diligently
commence and complete such Work in a good and workmanlike manner.

      (g)   If an Event of Default shall have occurred and be continuing or if
Tenant (i) shall fail to submit to Landlord or Lender for approval plans and
specifications (if required pursuant to Section 3.7 (a) (i) hereof) for the Work
(approved by the Architect and by all governmental authorities whose approval is
required), (ii) after any such plans and specifications are approved by all such
governmental authorities, the Architect, Landlord and Lender, shall fail to
commence promptly such Work, (iii), shall fail to diligently prosecute such Work
to completion (after Lender or Landlord has released the Net Proceeds if and to
the extent provided for hereunder), or (iv) materially fail in any other respect
to comply with the Work obligations under this Section, then in addition to all
other rights available hereunder, at law or in equity, Landlord or Lender, or
any receiver of the Premises or any portion thereof, upon fifteen days prior
written notice to Tenant (except in the event of emergency in which case no
notice shall be required), may (but shall have no obligation to) perform or
cause to be performed such Work, and may take such other steps as either
Landlord or Lender deems advisable (but such performance shall not cure the
default of Tenant). In addition, if an Event of Default shall have occurred and
be continuing, Lender may apply any Net Proceeds towards payment of a Loan,
which payment shall not relieve Tenant of any of its obligations hereunder.
Tenant hereby waives, for Tenant and all others holding under or through Tenant,
any claim, other than for gross negligence or willful misconduct, against
Landlord and Lender and any receiver arising out of any act or omission of
Landlord or Lender or such receiver pursuant hereto, and Landlord or Lender may
apply all or any portion of the Net Proceeds (without the need to fulfill any
other requirements forth in this Section) to reimburse Landlord or Lender or
such receiver, for all amounts incurred in connection with the Work, and any
costs not reimbursed to such parties shall be paid by Tenant to Landlord (or
such other party) on demand, together with interest thereon at the Default Rate
from the date such amounts are advanced until the same are paid by Tenant.

                                       16

3.6   Insurance.

      (a)   Tenant will maintain insurance on the Premises of the following
types and amounts:

            (i)   Insurance against loss or damage to the Improvements and
Equipment under a fire and broad form of all risk extended coverage insurance
policy. Such insurance shall be in amounts sufficient to prevent Landlord or
Tenant from becoming a co-insurer under the applicable policies, and in any
event in amounts not less than the actual replacement cost of the Improvements
and Equipment (excluding footings and foundations and other parts of the
Improvements which are not insurable) as determined from time to time at
Lender's request but not more frequently than once in any 12-month period, by
agreement of Landlord, Lender and Tenant, or if not so agreed, at Tenant's
expense, by the insurer or insurers or by an appraiser approved by Landlord.
Such insurance policies may contain reasonable and necessary exclusions and
deductible amounts not to exceed two percent of the Stipulated Loss Value.

            (ii)  Worker's compensation insurance to the extent required by the
law of the state in which the Premises are located.

            (iii) Insurance against loss or damage from explosion of any steam
or pressure boilers or similar apparatus located in or about the Improvements in
an amount not less than the actual replacement cost of the Improvements and
Equipment (excluding footings and foundations and other parts of the
Improvements which are not insurable).

            (iv)  Flood insurance in an amount equal to the full Replacement
Cost of the Premises or the maximum amount available through National Flood
Program or any successor program, whichever is less, if all or any portion of
the Premises are located in an area which has been designated by the Secretary
of Housing and Urban Development or by the Federal Emergency Management Agency
as having special flood hazards, and if flood insurance is available under the
National Flood Insurance Act.

            (v)   So long as a Loan is still outstanding, if the Premises or any
part thereof are situated in an area subsequently designated as a "Zone 3 or
Zone 4 Earthquake Zone" by the Uniform Building Code, earthquake insurance in an
amount equal to the replacement cost of the Improvements or the maximum amount
of earthquake insurance available, whichever is the lesser, unless Lender waives
this requirement in writing after review of a seismic report (prepared according
to Lender's requirements) provided to Lender by Tenant, at Tenant's expense.
Tenant represents that no part of the Premises are situated in an area
currently designated as a "Zone 3 or Zone 4 Earthquake Zone" by the Uniform
Building Code.

            (vi)  Such other insurance (including without limitation, rent loss
insurance in an amount equal to twelve months Basic Rent) as may from time to
time be reasonably required by Landlord or, as required by an Indenture, by
Lender in order to protect their respective interests, provided

                                       17
<PAGE>
that such insurance is then customarily maintained by prudent owners or tenants
with respect to improvements similar in character, location, use and occupancy
to the Improvements or is then customarily required by prudent lenders with
respect to mortgage loans secured by similar properties.

            (vii) Tenant shall also maintain commercial general public liability
insurance insuring Tenant, with Landlord and Lender as additional insureds,
against claims for bodily injury and property damage or for loss of life arising
out of the occupation, ownership or use of the Premises, with coverage for
personal injury, bodily injury and property damage of not less than $30 million
combined single limit coverage per occurrence in the aggregate in any given
policy year, or such greater limits as may be required from time to time by
Landlord or, as required by an Indenture, Lender consistent with insurance
coverage on properties similarly constructed, occupied and maintained.

      (b)   Such insurance shall be issued by companies authorized to transact
business in the state in which the Premises are located and having an A.M. Best
Company rating of A or better and financial size category of not less than X,
and a Standard & Poor's rating of A or better as to claims paying ability,
provided that with respect to worker's compensation insurance such insurance
company must have an A.M. Best Company rating of A or better and financial size
category of not less than VIII. No casualty or other insurance policy maintained
by Tenant hereunder shall provide for a deductible or self-insured retention in
excess of $100,000.

      (c)   Every such policy (other than any general public liability or
worker's compensation policy) shall bear a mortgagee's loss payable clause or a
mortgagee endorsement in favor of Lender and each other mortgagee or beneficiary
(whether one or more, and together with its or their successors and assigns, the
"Junior Lenders") under each mortgage, deed of trust or similar security
instrument (other than an Indenture) creating a lien on the interests of
Landlord in the Premises (the "Junior Indentures"), and any loss under any such
policy shall be payable to Lender to be held and applied pursuant to this
Article 3.

      (d)   Each policy (other than worker's compensation policy) shall provide
that (i) it may not be canceled or materially changed except after 30 days prior
notice to Landlord, Lender and the Junior Lenders, (ii) any losses otherwise
payable thereunder shall be payable notwithstanding (A) any act or omission of
Landlord or Tenant which might, absent such provision, result in a forfeiture of
all or a part of such insurance payment, or (B) the occupation or use of any of
the Premises for purposes more hazardous than permitted by the provisions of
such policy and (iii) the insurer thereunder waives all rights of subrogation
against the Lender, Junior Lenders and Landlord and waives any right of set-off.

                                       18
<PAGE>
      (e)   Tenant shall pay as they become due all premiums for the insurance
required by this Section 3.6, shall renew or replace each policy, and shall
deliver to Landlord, Lender and the Junior Lenders a certificate or other
evidence (reasonably satisfactory to Lender and Landlord) of the existing policy
and such renewal or replacement policy at least thirty days prior to the Policy
Expiration Date (as herein defined) of each policy. Each such policy shall
provide that it shall not expire or terminate until the Landlord, Lender and
Junior Lenders shall receive a notice from the insurer to the effect that a
policy will expire on a date (the "Policy Expiration Date") which shall be
thirty (30) days following the date of the receipt by Landlord, Lender and
Junior Lenders of such notice. In the event of Tenant's failure to comply with
any of the foregoing requirements of this Section 3.6 within five (5) business
days of the giving of the written notice by Landlord to Tenant, Landlord shall
be entitled to procure such insurance. Any sums expended by Landlord in
procuring such insurance shall be Additional Rent and shall be repaid by Tenant,
together with interest thereon at the Default Rate, from the time of payment by
Landlord until fully paid by Tenant immediately upon written demand therefor by
Landlord.

      (f)   Anything in this Article 3 to the contrary notwithstanding, any
insurance which Tenant is required to obtain pursuant to Section 3.6 may be
carried under a "blanket" policy or policies covering other properties or
liabilities of Tenant, provided that such "blanket" policy or policies otherwise
comply with the provisions of this Section and includes an agreed upon amount
endorsement for the Premises in an amount not less than the Stipulated Loss
Value less the value of the Land and the footings, foundations and other parts
of the Improvements which are not insurable. In the event any such insurance is
carried under a blanket policy, Tenant shall deliver to Landlord and Lender
evidence of the issuance and effectiveness of the policy, the amount and
character of the coverage with respect to the Premises and the presence in the
policy of provisions of the character required in this Section 3.6.

      (g)   Any loss under any property damage insurance required to be
maintained by Tenant shall be adjusted by Landlord, Lender and Tenant pursuant
to the provisions of Section 3.2(a), provided, however, if an Event of Default
shall have occurred and be continuing, Landlord and Lender shall have the sole
right to make such adjustment and collection, but Tenant shall be entitled to
any proceeds relating to Tenant's Personal Property (subject to Landlord's right
to offset any amounts owed to Landlord under this Lease).

      (h)   The requirements of this Section shall not be construed to negate or
modify Tenant's obligations under Section 2.4.

3.7   Alterations.

      (a)   Tenant may, at its expense, make additions to and alterations of the
Improvements, and construct additional Improvements (collectively,
"Alterations"), provided that (1) the fair market value, utility and useful life
of the Premises shall not be reduced or lessened in any material respect
thereby, (2) such Alterations shall be expeditiously completed in a good and

                                       19
<PAGE>
workmanlike manner, free and clear of liens and encumbrances, and in compliance
with all applicable Legal Requirements and the requirements of all insurance
policies required to be maintained by Tenant hereunder, (3) Tenant shall not
make any Alterations in violation of the terms of any restriction, easement,
condition, covenant or other matter affecting title to or use of the Premises
and (4) no Material Alterations (as hereinafter defined), shall be made unless
Landlord's and Lender's prior written consent shall have been obtained, which
consent shall not be unreasonably withheld, delayed or conditioned, unless an
Event of Default shall have occurred and be continuing in which case such
consent may be withheld by Landlord or Lender in its sole discretion. "Material
Alteration" is defined as Work that reduces the footprint or rentable square
footage of the Improvements or the parking area or for which the estimated cost
is in excess of $500,000 multiplied by 1.015 raised to the n power where n is
the number of whole (12 month) years that have elapsed since the Commencement
Date and prior to commencement of Work. In addition to the limitations set forth
in (1) through (4) above, Tenant agrees that all Alterations, Material
Alterations, restoration, repair and any other work which Tenant shall be
required or permitted to do under the provisions of this Lease (hereinafter
collectively called the "Work") shall be performed in each case subject to the
following:

            (i)   No Material Alterations shall be commenced until detailed
plans and specifications (including layout, architectural, mechanical and
structural drawings), prepared by an Architect shall have been submitted to and
approved by Landlord and, if a Loan is outstanding, Lender, and no such Work
shall be undertaken except under the supervision of the Architect.

            (ii)  All Work shall be commenced only after all required municipal
and other governmental permits, authorizations and approvals shall have been
obtained by Tenant, at its own cost and expense.

            (iii) If the Work shall constitute a Material Alteration, it shall
not be commenced until Tenant shall have obtained and delivered to Landlord, and
as required by an Indenture, Lender, either (A) a performance bond and a labor
and materials payment bond (issued by a corporate surety licensed to do business
in the state in which the Premises are located and satisfactory to Landlord and,
as required by an Indenture, Lender), each in an amount equal to the estimated
cost of such Work and in form otherwise satisfactory to Landlord, and as
required by an Indenture, Lender, or (B) such other security as shall be
reasonably satisfactory to Landlord, and as required by an Indenture, Lender;
provided, however, that if at the time the Work is commenced, either Tenant or a
Guarantor then maintains and continues to maintain until such Work is completed
an Investment Grade Rating and no Event of Default shall have occurred and be
continuing and estimated cost of the Work does not exceed $1 million, Tenant
shall not be required to comply with this subsection (iii).

            (iv)  Subject to the terms of Section 2.6 hereof, the cost of all
Work shall be paid promptly, in cash, so that the Premises and Tenant's
leasehold estate therein shall at all times be free from (A) liens for labor or
materials supplied or claimed to have bean supplied to the Premises or

                                       20
<PAGE>
Tenant, and (B) chattel mortgages, conditional sales contracts, title retention
agreements, security interest and agreements, and financing agreements and
statements.

            (v)   Upon completion of any Work, Tenant, at Tenant's expense,
shall obtain certificates of final approval of such Work required by any
governmental authority and shall furnish Landlord with copies thereof, and, if
the Work constituted Material Alterations, together with "(as-built)" plans and
specifications for such Work.

            (vi)  Any Work shall be subject to inspection at any time and from
time to time by any of Landlord or, as required by an Indenture, Lender, their
respective architect(s), or their duly authorized construction representatives,
and if any such party upon any such inspection shall be of the opinion that the
Work is not being performed in accordance with the provisions of this Section or
the plans and specifications, or that any of the materials or workmanship are
unsound or improper, Tenant shall correct any such failure and shall replace any
unsound or improper materials or workmanship. Anything contained herein to the
contrary notwithstanding, any different procedure for the performance of Work
which may be required under any Indenture shall take precedence over and be in
addition to the procedures provided for in this Lease.

            (vii) Except as may be expressly provided to the contrary hereunder
with respect to Tenant's Personal Property, all Alterations installed in or upon
the Premises at any time during the Term shall become the property of Landlord
and shall remain upon and be surrendered with the Premises unless Landlord, by
notice to Tenant no later than ninety (90) days prior to the scheduled
expiration (or within 90 days after any earlier termination) of this Lease,
elects to have the same removed or demolished by Tenant, in which event, the
same shall be removed from the Premises by Tenant prior to the scheduled
expiration (or within 90 days after any earlier termination) of this Lease, at
Tenant's expense. Landlord shall not require Tenant to remove or demolish any
Alterations unless in Landlord's reasonable judgment, such Alterations (A)
materially reduce the fair market value or fair market rent of the Premises (B)
are functionally obsolete (C) are special purpose or (D) are in violation of
then applicable law. Tenant may expressly request in Tenant's written request
for consent that Landlord determine its election prior to installation (which
written request shall include the estimated cost of removal and restoration).
Tenant shall immediately repair any damage to the Premises caused by its removal
of any of Tenant's Personal Property or Alterations that remain the property of
Tenant pursuant to the terms of this Section. All property permitted or required
to be removed by Tenant at the end of the Term remaining in the Premises after
Tenant's removal shall be deemed abandoned and may, at the election of Landlord,
either be retained as Landlord's property or may be removed from the Premises by
Landlord at Tenant's expense. The provisions of this Section shall survive the
expiration or earlier termination of the Term.

                                       21
<PAGE>
      (b)   Tenant may, at its cost and expense, install, or place upon or
reinstall, or replace and remove from the Premises any Tenant's Personal
Property.

3.8   Easements.

      (a)   Landlord agrees to enter into, at Tenant's expense, such easements,
covenants, waivers, approvals or restrictions for utilities, parking or other
matters as desirable for operation of the Premises or properties adjacent
thereto (collectively, "Easements") as reasonably requested by Tenant, subject
to Lender's and Landlord's approval of the form thereof, not to be unreasonably
withheld or delayed; provided, however, that no such Easement shall result in
any reduction in parking or any diminution in the value or utility of the
Premises for its current use and further provided that no such Easement shall
render the use of the Premises dependent upon any other property or condition
the use of the Premises upon the use of any other property, each of which Tenant
shall certify to Landlord and Lender in writing delivered with Tenant's request
with respect to such Easement. Tenant shall pay Landlord's and Lender's
reasonable attorney's fees and other out-of-pocket expenses and Lender's
customary fees incurred in connection with any request made by Tenant hereunder.

      (b)   Tenant agrees that Tenant is obligated to and shall perform all
obligations of the owner of the Premises under and pay all expenses which the
owner of the Premises may be required to pay in accordance with any reciprocal
easement agreement or any other agreement or document of record now affecting
the Premises, herein referred to collectively as the "REA", and that Tenant
shall comply with all of the terms and conditions of the REA during the term of
this Lease. Tenant further covenants and agrees to indemnify, defend and hold
harmless Landlord and Lender against any claim, loss or damage suffered by
Landlord or Lender by reason of Tenant's failure to perform any obligations or
pay any expenses as required under any REA or comply with the terms and
conditions of any REA as hereinabove provided during the term of this Lease.

3.9   Equipment. Tenant acknowledges that the Equipment is the property of
Landlord and that Landlord has granted, and may hereafter grant, a security
interest therein to Lender. Tenant hereby represents and warrants to Landlord
that the Equipment is free and clear of any and all liens, security interests or
other encumbrances as of the date hereof, other than the lien and security
interest of an Indenture. Tenant hereby agrees to maintain the Equipment in good
condition and repair. In no event shall any of the Landlord's Equipment be
discarded or removed from the Premises unless such Equipment is replaced by
similar Equipment with a value at least equal to the value of the replaced
Equipment. Notwithstanding the foregoing, at the end of the Primary Term, Tenant
may remove any radiology, laboratory, diagnostic, treatment and other medical
equipment so long as (a) such equipment is readily removable without material
damage and (b) as part of such removal, Tenant restores the Premises to like new
condition.

                                   ARTICLE 4.

4.1   Assignment and Subletting.

      (a)   So long as no Event of Default shall have occurred and be
continuing, Tenant may sublet the Premises (including, but not limited to,
subleases to affiliates of Tenant) and in connection therewith cause such
sublessee to perform Tenant's obligations hereunder; provided, however, (i) each
such sublease shall expressly be made subject to the provisions hereof, (ii) the
term of any subletting shall not extend beyond the Term of this Lease, (iii) no
sublease shall affect or reduce any obligation of the Tenant or right of the
Landlord hereunder, (iv) all obligations of the Tenant hereunder shall continue
in full force and effect as the obligations of a principal and not of a
guarantor or surety, as though no subletting had been made and (v) so long as a
Loan is outstanding, Tenant may not sublet the Premises to any entity
unaffiliated with Tenant if the aggregate rentable square feet covered by such
sublease and all other subleases to entities unaffiliated with Tenant exceeds
ten percent of the total rentable square feet in the Improvements (except with
Lender's written consent which shall not be unreasonably withheld.) Neither this
Lease nor the term hereby demised shall be mortgaged or pledged by Tenant, nor
shall Tenant mortgage or pledge its interest in any sublease of any portion of
the Premises or the rentals payable thereunder. Any such mortgage or pledge, any
sublease made other than as expressly permitted by this Section 4.1, and any
assignment of Tenant's interest hereunder made other than as expressly permitted
by this Section 4.1, shall be void. Tenant shall, within 10 days after the
execution of any sublease, deliver a conformed copy thereof to Landlord and
Lender.

      (b)   So long as no Event of Default shall have occurred and be
continuing, Tenant may assign this Lease or merge with another entity, or a
change in control of Tenant may occur provided, however, (i) each such
assignment shall expressly be made subject to the provisions hereof, (ii)
Guarantor shall specifically approve such assignment or change in control of
Tenant or Tenant merger and shall confirm in writing its continuing obligations
under its guaranty, (iii) Tenant (and in the case of any Tenant merger, the
surviving entity) and Guarantor shall deliver such estoppels, certificates,
opinions of counsel (concerning the continuing enforceability of this Lease, any
Subordination, Non-Disturbance and Attornment Agreement in effect immediately
prior to the assignment, change in control or merger and Guarantor's guaranty
and any other document assigned thereby), and other instruments as may be
reasonably required by Landlord or, as required by an Indenture, Lender, (iv)
the assignee (or in the case of a Tenant merger, the surviving entity) shall
specifically assume all obligations of Tenant under this Lease and under any
other agreement of Tenant related hereto or thereto, (v) all obligations of the
Tenant hereunder shall continue in full force and effect as the obligations of a
principal and not of a guarantor or surety, as though no assignment had been
made, (vi) the assignee (or in the case of a Tenant merger, the surviving
entity) must be a solvent entity, (vii) the assignee (or in the case of a Tenant
merger, the surviving entity) must either be an entity formed in the United
States or must specifically consent to jurisdiction in Nevada, and must provide
an opinion in form reasonably

                                       23
<PAGE>
acceptable to Landlord and, as required by an Indenture, to Lender that such
consent to jurisdiction is enforceable and valid (viii) in the case of a Tenant
merger or change in control of Tenant, at least 30 days prior to the merger or
change in control, Tenant must have notified Landlord and Lender of the material
terms of the merger or change in control and (ix) so long as a Loan is
outstanding, any assignment, change in control of Tenant or Tenant merger
involving an entity unaffiliated with Tenant shall not be permitted without the
prior written consent of Landlord and Lender which shall not be unreasonably
withheld. Upon Landlord's and Lender's receipt of Tenant's written request for
consent together with all material terms of the assignment, change in control or
merger and such other information that Lender shall reasonably request (which
request shall be made within five Business Days after receipt of Tenant's
written request and such material terms), Landlord and Lender shall have fifteen
Business Days to respond. Failure to respond within such time shall be deemed
consent. If Lender or Landlord disapproves any such transaction, it shall
provide Tenant in writing the reasons for disapproval in reasonable detail. In
determining whether consent is reasonable, the following criteria shall be
considered:

      (A)   The overall financial responsibility of the new tenant.

      (B)   Whether the proposed use of the Premises would be similar to the
current Tenant's use.

      (C)   The proposed new tenant's suitability to use the Premises.

      (D)   The expected economic feasibility of the proposed new tenant to meet
the current Tenant's Lease obligations.

      (E)   The level of experience of the new tenant in operating and managing
buildings similar in character, age and size to the Premises.

      A certified copy of the executed assignment or merger document approved by
Landlord shall be provided to Landlord and Lender within ten (10) days after the
execution thereof.

      (c)   Except in compliance with Section 4.1 (a) or (b), neither this
Lease, nor any interest of Tenant in this Lease or in the Premises, shall be
sold, assigned, or otherwise transferred, directly or indirectly, whether by
operation of law or otherwise, nor shall any of the issued or outstanding
capital stock of Tenant be sold, assigned or transferred, nor shall additional
stock in Tenant be issued if the issuance of additional stock will result in a
change of the controlling stock ownership of Tenant as held by the shareholders
thereof on the date hereof (or on the date that Landlord approved the transfer
to the holder of Tenant's leasehold interest in this Lease). The transfer of
stock of Tenant for the purposes of this Section 4.1 shall not include the sale,
issuance or exchange of shares, which sale, issuance or exchange is effected
through the "over-the-counter market" or through any recognized stock exchange.
In no event shall any assignment, sublease or license relieve Tenant of any
liability or obligation under this Lease, which shall be and remain that of a
primary obligor and not a

                                       24
<PAGE>
guarantor or surety. For the purposes of this Article and Section 5.1(a),
"control" or "controlling" means the power to direct the management and policies
of the applicable party, directly or indirectly, whether through ownership of
voting securities or other beneficial interests, by contract or otherwise.

      (d)   Without implying any authority of Tenant to assign this Lease, if
this Lease is assigned whether or not pursuant to the provisions hereof,
Landlord may collect rent from the Assignee, or if the Premises or any part
thereof are sublet or occupied by any person or entity other than Tenant,
Landlord may, after an Event of Default has occurred and is continuing, collect
rent from the subtenant or occupant, and in all such cases apply the net amount
collected to the Basic Rent and Additional Rent herein reserved. However, no
such assignment, subletting, occupancy or collection shall be deemed a waiver of
the provisions of this Article, or the acceptance of the assignee, subtenant or
occupant as Tenant, or a release of Tenant from the further performance by
Tenant of the terms, covenants, and conditions on the part of Tenant to be
observed or performed hereunder, and, subsequent to any assignment or
subletting, Tenant's liability hereunder shall continue notwithstanding any
subsequent modification or amendment hereof or the release of any subsequent
tenant hereunder from any liability, to all of which Tenant hereby consents in
advance.

                                   ARTICLE 5.

5.1   Conditional Limitations; Default Provisions.

      (a)   Any of the following occurrences or acts shall constitute an "Event
of Default" under this Lease:

            (i)   if Tenant shall (1) fail to pay any Basic Rent, Additional
Rent or other sum as and when required to be paid by Tenant hereunder, and such
failure shall continue for three Business Days after written notice to Tenant of
such default, or (2) fail to observe or perform any other provision hereof
(other than those specified in clauses (ii)-(x) of this subsection 5.1(a)) and
such failure shall continue for thirty (30) days after written notice to Tenant
of such failure (provided, that in the case of any such failure which is capable
of being cured but cannot be cured by the payment of money and cannot with
diligence be cured within such 30-day period, if Tenant shall commence promptly
to cure the same and thereafter prosecute the curing thereof with diligence, the
time within which such failure may be cured shall be extended for such period as
is necessary to complete the curing thereof with diligence, but in no event to
exceed 180 days from the date of such original failure); or

            (ii)  if any representation or warranty of Tenant or Guarantor set
forth herein or in any notice, certificate, demand, request or other document or
instrument delivered to Landlord in connection with this Lease

                                       25
<PAGE>
shall prove to be incorrect in any material respect as of the time when the same
shall have been made; or

            (iii) if Tenant or Sierra Health Services, Inc., a Nevada
corporation (" Guarantor" ) shall file a petition in bankruptcy or for
reorganization or for an arrangement, administration, liquidation or
receivership pursuant to any federal or state law (or any other law governing
Guarantor), or shall be adjudicated a bankrupt or become insolvent or shall make
an assignment for the benefit of creditors or shall admit in writing its
inability to pay its debts generally as they become due, or if a petition or
answer proposing the adjudication of Tenant or Guarantor as a bankrupt or its
reorganization pursuant to any federal or state bankruptcy, liquidation,
voluntary administration, administration, receivership, moratorium or trust law
or any similar federal or state law shall be filed in any court and Tenant or
Guarantor shall consent to or acquiesce in the filing thereof or such petition
or answer shall not be discharged or denied within ninety (90) days after the
filing thereof; or

            (iv)  if a receiver, trustee, administrator or liquidator of Tenant
or Guarantor or of all or substantially all of the assets of Tenant or Guarantor
or of the Premises or Tenant's estate therein shall be appointed in any
proceeding brought by Tenant or Guarantor, or if any such receiver, trustee or
liquidator shall be appointed in any proceeding brought against Tenant or
Guarantor and shall not be discharged within ninety (90) days after such
appointment, or if Tenant or Guarantor shall consent to or acquiesce in such
appointment; or

            (v)   if Guarantor shall dissolve or otherwise fail to maintain its
legal existence; or

            (vi)  if Tenant shall default under Section 4.1 of this Lease; or

            (vii) if Guarantor shall default under the provisions of its
guaranty;

            (viii) if an Event of Default shall occur and continue under any of
the leases set forth in Schedule G and the landlord thereunder is the same as,
or is an affiliate of, the Landlord under this Lease; or

            (ix)  if Tenant shall fail to maintain or replace any insurance
required to be maintained or replaced by Tenant in accordance with the terms and
conditions of Section 3.6 hereof; or

            (x)   if Tenant shall dissolve or otherwise fail to maintain its
legal existence unless such dissolution or termination of Tenant's legal
existence occurs in connection with a merger completed in accordance with
Section 4.1(b).

            (As used in Section 5.1 (a) (viii), an entity is an "affiliate" of
Landlord if such entity controls, is controlled by, or is under common control
with, Landlord or any entity controlling Landlord.)

                                       26
<PAGE>
      (b)   If an Event of Default shall have occurred and be continuing
Landlord shall be entitled to all remedies available at law or in equity.
Without limiting the foregoing, Landlord (with Lender's consent) shall have the
right to give Tenant notice of Landlord's termination of the term of this Lease.
Upon the giving of such notice, the term of this Lease and the estate hereby
granted shall expire and terminate on such date as fully and completely and with
the same effect as if such date were the date herein fixed for the expiration of
the term of this Lease, and all rights of Tenant hereunder shall expire and
terminate, but Tenant shall remain liable as hereinafter provided.

      (c)   If an Event of Default shall have occurred and be continuing,
Landlord shall have the immediate right, whether or not the term of this Lease
shall have been terminated pursuant to Section 5.1(b), to re-enter and repossess
the Premises and the right to remove all persons and property therefrom by
summary proceedings, ejectment, any other legal action or in any lawful manner
Landlord determines to be necessary or desirable, so long as Landlord is
proceeding in accordance with applicable law and, if required under applicable
law, under authority of a court of proper jurisdiction. Landlord shall be under
no liability by reason of any such re-entry, repossession or removal. No such
re-entry, repossession or removal shall be construed as an election by Landlord
to terminate this Lease unless a notice of such termination is given to Tenant
pursuant to Section 5.1(b).

      (d)   At any time or from time to time after a re-entry, repossession or
removal pursuant to Section 5.1(c), whether or not the term of this Lease shall
have been terminated pursuant to Section 5.1(b), Landlord may (but shall be
under no obligation to) relet the Premises for the account of Tenant, in the
name of Tenant or Landlord or otherwise, without notice to Tenant, for such term
or terms and on such conditions and for such uses as Landlord, in its absolute
discretion, may determine. Landlord may collect any rents payable by reason of
such reletting. Landlord shall not be liable for any failure to relet the
Premises or for any failure to collect any rent due upon any such reletting.

      (e)   No expiration or earlier termination of the term of this Lease
pursuant to Section 5.1(b), by operation of law or otherwise, and no reentry,
repossession or removal pursuant to Section 5.1(c) or otherwise, and no
reletting of the Premises pursuant to Section 5.1(d) or otherwise, shall relieve
Tenant of its liabilities and obligations hereunder, all of which shall survive
such expiration, termination, re-entry, repossession, removal or reletting.

      (f)   In the event of the expiration or earlier termination of the term
of this Lease or re-entry or repossession of the Premises or removal of persons
or property therefrom by reason of the occurrence of an Event of Default, and
subject to applicable law, Tenant shall pay to Landlord all Basic Rent,
Additional Rent and other sums required to be paid by Tenant, in each case
together with interest thereon at the Default Rate from the due date thereof to
and including the date of Such expiration, termination, re-

                                       27
<PAGE>
entry, repossession or removal; and thereafter, Tenant shall, until the end of
what would have been the term of this Lease in the absence of such expiration,
termination, re-entry, repossession or removal and whether or not the Premises
shall have been relet, be liable to Landlord for, and shall pay to Landlord, as
damages: (i) all Basic Rent, Additional Rent and other sums which would be
payable under this Lease by Tenant in the absence of any such expiration,
termination, re-entry, repossession or removal, less (ii) the net proceeds, if
any, of any reletting effected for the account of Tenant pursuant to Section
5.1(d), after deducting from such proceeds all expenses of Landlord in
connection with such reletting (including, without limitation, all repossession
costs, brokerage commissions, reasonable attorneys' fees and expenses (including
fees and expenses of appellate proceedings), employees' expenses, alteration
costs and expenses of preparation for such reletting). Tenant shall pay such
damages on the dates on which Basic Rent would be payable under this Lease in
the absence of such expiration, termination, re-entry, repossession or removal,
and Landlord shall be entitled to recover the same from Tenant on each such
date.

      (g)   At any time after any such expiration or earlier termination of the
term of this Lease or re-entry or repossession of the Premises or removal of
persons or property thereon by reason of the occurrence of an Event of Default,
whether or not Landlord shall have previously collected any damages pursuant to
Section 5.1(f), Landlord shall be entitled to recover from Tenant, and Tenant
shall pay to Landlord on demand, as additional damages for Tenant's default and
in lieu of damages beyond the date of such demand as outlined in Section 5.1 (f)
above, an amount equal to the excess, if any, of (a) the aggregate of all Basic
Rent, Additional Rent and other sums which would be payable under this Lease, in
each case from the date of such demand (or, if it be earlier, the date to which
Tenant shall have satisfied in full its obligations to pay damages under Section
5.1(f)) for what would be the then-unexpired Term in the absence of such
expiration, termination, re-entry, repossession or removal, discounted at a rate
equal to the then yield on U.S. Treasury obligations of comparable maturity to
the Term (the "Treasury Rate") over (b) the then fair rental value of the
Premises for what would be such then unexpired term of this Lease, discounted at
the Treasury Rate for the same period (such excess being hereinafter referred to
as "Future Rental Damages"). For purposes of determining value pursuant to this
Section 5.1(g), the following shall apply: (a) determinations of fair rental
value shall be made by an Appraiser (engaged by Landlord), with copies of such
determinations and supporting analysis to be provided to Tenant; and (b) all
determinations of Future Rental Damages shall be binding on Tenant in the
absence of manifest error. If any law shall limit the amount of Future Rental
Damages to less than the amount above agreed upon, Landlord shall be entitled to
the maximum amount allowable under such law.

5.2   Additional Rights of Landlord.

      (a)   No right or remedy hereunder shall be exclusive of any other right
or remedy, but shall be cumulative and in addition to any other right or remedy
hereunder or now or hereafter existing. Failure to insist upon the strict
performance of any provision hereof or to exercise any option, right,

                                       28
<PAGE>
power or remedy contained herein shall not constitute a waiver or relinquishment
thereof for the future. Receipt by Landlord of any Basic Rent, Additional Rent
or other sums payable hereunder with knowledge of the breach of any provision
hereof shall not constitute waiver of such breach, and no waiver by Landlord of
any provision hereof shall be deemed to have been made unless made in writing
duly executed by Landlord. Landlord shall be entitled to injunctive relief in
case of the violation, or attempted or threatened violation, of any of the
provisions hereof, or to a decree compelling performance of any of the
provisions hereof, or to any other remedy allowed to Landlord by law or equity.

      (b)   Tenant hereby waives and surrenders for itself and all those
claiming under it, including creditors of all kinds, (i) any right and privilege
which it or any of them may have to redeem any portion of the Premises or to
have a continuance of this Lease after termination of Tenant's right of
occupancy by order or judgment of any court or by any legal process or writ, or
under the terms of this Lease, or after the termination of the term of this
Lease as herein provided, and (ii) the benefits of any law which exempts
property from liability for debt or for distress for rent.

      (c)   If Tenant shall be in default in the observance or performance of
any term or covenant on Tenant's part to be observed or performed under any of
the provisions of this Lease, then, without thereby waiving such default,
Landlord may, but shall be under no obligation to, take all action, including,
without limitation, entry upon the Premises to perform the obligation of Tenant
hereunder immediately and without notice in the case of an emergency and upon 5
days' written notice to Tenant in other cases. All expenses incurred by Landlord
in connection therewith, including attorneys' fees and expenses (including those
incurred in connection with any appellate proceedings), together with interest
thereon at the Default Rate from the date any such expenses were incurred by
Landlord until the date of payment by Tenant, shall constitute Additional Rent
and shall be paid by Tenant to Landlord upon demand.

      (d)   If Tenant shall be in default in the performance of any of its
obligations hereunder, Tenant shall pay to Landlord or Lender, as appropriate,
on demand, all expenses incurred by Landlord or Lender as a result thereof,
including reasonable attorneys' fees and expenses (including those incurred in
connection with any appellate proceedings) and any Makewhole Premium incurred
by Landlord. If Landlord or Lender shall be made a party to any litigation
commenced against Tenant and Tenant shall fail to provide Landlord or Lender
with counsel reasonably approved by Landlord or Lender, as applicable, and pay
the expenses thereof, Tenant shall pay all costs and reasonable attorneys' fees
and expenses in connection with such litigation (including fees and expenses
incurred in connection with any appellate proceedings) together with interest at
the Default Rate, from the date paid by Landlord or Lender until reimbursed by
Tenant.

      (e)   So long as a Loan is outstanding, if an Event of Default shall
exist, within five days after written demand from Landlord or Lender, Tenant
shall make monthly tax and insurance payments into an escrow account in

                                       29
<PAGE>
accordance with the applicable provisions of an Indenture for so long as such
Event of Default shall continue to exist.

Tenant shall agree:

                                       31
<PAGE>
            (i) that in the event that any such Lender, or any purchaser at a
foreclosure sale, shall acquire title to the Premises, Tenant shall attorn to
such Lender or such purchaser, as the case may be, as its new Landlord and this
Lease shall continue as a direct lease between Tenant and such Lender or
purchaser, as the case may be, with respect to the Premises upon the terms and
conditions set forth herein except that such Lender or purchaser, as the case

prior to the date such Lender or purchaser, as the case may be, acquired title

            (ii) Tenant shall not enter into any agreement with Landlord for the

Lease upon assignment of this Lease or sublease of the Premises shall be

            (vi) no subordination, amendment or modification of this Lease shall
be effective unless Tenant receives the written consent of the Lender thereto
and written evidence in writing from the applicable rating agencies, if any,
that any such action shall not result in a withdrawal, qualification or
downgrade of the current ratings for any securities issued in connection with
any securitization or other secondary market transaction in which the
indebtedness secured by an Indenture is included; and

            (vii) Tenant will not pay any installment of Basic Rent more than
one month in advance of the due date thereof or otherwise than in the manner
provided for in this Lease.

            (viii) to the other material terms for the benefit of the current
Lender set forth in the Subordination, Non-Disturbance and Attornment Agreement
entered into concurrently with the commencement of this Lease.

      (d) Upon receipt of a request from Landlord for the agreement described in
Section 6.2 (c) above, Tenant's obligations under Section 6.2 (c) above shall be
conditioned upon such Lender entering into a subordination, non-disturbance and
attornment agreement in customary form acceptable to Lender which shall
incorporate the agreement described in Section 6.2 (c) and provide that unless
an Event of Default then exists under this Lease, Lender shall not join Tenant
as a defendant in any action to foreclose upon the interest of Landlord in the
Premises and, upon the Lender's foreclosure of Landlord's interest in the
Premises by judicial proceedings or otherwise,

                                       32
<PAGE>
such Lender or other purchaser at the foreclosure sale shall not be entitled to,
nor shall it seek to terminate this Lease or Tenant's interest in the Premises,
provided, that, Tenant, from and after the date of such succession, attorns to
such Lender or purchaser, pays to such Lender or purchaser all items of Basic
Rent, Additional Rent and other items accruing from and after such date and
otherwise remains in compliance with all other terms and provisions of this
Lease. In the event that Tenant shall execute a separate document for the
benefit of a Lender relating to subordination, attornment or non-disturbance,
such document shall control to the extent that it conflicts with the provisions
of this Section 6.2 (d).

                                       34
<PAGE>
      (c) To the extent required by any Environmental Law, Tenant shall remove
any Hazardous Substance whether now or hereafter existing on the Premises and
whether or not arising out of or in any manner connected with Tenant's occupancy
of the Premises during the Term. Tenant shall and hereby does agree to defend,

or covenant set forth in this Lease.

7.2 Notice. Promptly upon obtaining knowledge thereof, Tenant shall give to
the Landlord and Lender notice of the occurrence of any of the following events:

manner whatsoever except for the use or disposal of incidental amounts of
Hazardous Substances customarily used in the operation of similar buildings
similarly situated in a commercially reasonably manner and in compliance with
Legal Requirements; (ii) the issuance to the Tenant or any tenant of space in

for information, complaint or order of violation or noncompliance or liability
of any nature whatsoever with regard to the Premises or the use thereof with
respect to Environmental Laws; (iii) any notice of a pending or threatened
investigation as to whether the Tenant's (or its "subtenants" or "assignees")
operations on the Premises are in compliance with or may lead to liability to
the Tenant under, any Environmental Law; or (iv) the occurrence of an event or
the existence of a situation which is likely to result in a violation of
Environmental Laws at the Premises or which is likely to result in the Tenant
being liable to the Landlord by virtue of the indemnity given by the Tenant
pursuant to Section 7.1(c).

7.3 Survival. The indemnity obligations of the Tenant and the rights and
remedies of the Landlord and Lender under this Article 7 shall survive the
expiration or earlier termination of this Lease.

                                   ARTICLE 8.

8.1 Holdover. If the Tenant shall continue to occupy the Premises after the
expiration or earlier termination of this Lease, then Tenant shall be deemed to
be a holdover tenant, the tenancy of which shall be from month to month upon the
same provisions and conditions set forth in this Lease, except that Basic Rent
for the holdover period shall be an amount equal to 150% of the Basic Rent in
effect immediately prior to the holdover period. This Article 8 does not amount
to a waiver of the Landlord's right of reentry or

                                       35
<PAGE>
any other right granted under Article 5 and shall not constitute a consent to
any holdover by Tenant.

                                   ARTICLE 9.

9.1 No Merger. There shall be no merger of this Lease or of the leasehold estate
hereby created with the fee estate in the Premises by reason of the fact that
the same person acquires or holds, directly or indirectly, this Lease or the
leasehold estate hereby created or any interest herein or in such leasehold
estate as well as the fee estate in the Premises or any interest in such fee
estate.

9.2 Surrender. Upon the expiration or earlier termination of this Lease, Tenant
shall surrender the Premises to Landlord in good repair and condition. Tenant
shall remove from the Premises on or prior to such expiration or termination all
property situated thereon which is not owned by Landlord and shall repair any
damage caused by such removal. Property not so removed shall become the property
of Landlord, and Landlord may cause such property to be removed from the
Premises and disposed of, but the cost of any such removal and disposition and
of repairing any damage caused by such removal shall be borne by Tenant.
Landlord shall credit the net proceeds of a disposition of such property
actually realized by Landlord against such costs to be borne by Tenant, provided
that the Lease termination giving rise to such disposition was not caused by an
Event of Default hereunder. The provisions of this Section shall survive the
termination or expiration of this Lease.

9.3 Separability; Binding Effect. Each provision hereof shall be separate and
independent and the breach of any provision by Landlord shall not discharge or
relieve Tenant from any of its obligations hereunder. If any provision hereof is
held invalid or unenforceable, the remaining provisions hereof shall not be
affected thereby. All provisions contained in this Lease shall be binding upon,
inure to the benefit of, and be enforceable by, the successors and assigns of
Landlord to the same extent as if each such successor and assign were named as a
party hereto. All provisions contained in this Lease shall be binding upon the
successors and assigns of Tenant and shall inure to the benefit of and be
enforceable by the permitted successors and assigns of Tenant in each case to
the same extent as if each such successor and assign were named as a party
hereto.

9.4 Counterparts. This Lease may be executed in two or more counterparts, and
all such counterparts shall be deemed to constitute but one and the same
instrument.

9.5 Recording of Lease. Tenant will execute, acknowledge, deliver and cause to
be recorded or filed in the manner and place required by any present or future
law a memorandum of this Lease. Tenant shall be responsible for all costs and
expenses in connection with the recording of this Lease or a memorandum hereof.

                                       36
<PAGE>
9.6 No Brokers. Each of the Landlord and the Tenant represents and warrants to
the other that it has not dealt with any broker (other than CB Richard Ellis,
Inc. who will be compensated by Landlord) in connection with the purchase and
leasing of the Premises, and indemnifies the other against the claims of brokers
claiming through it.

9.7 Governing Law. The terms and provisions of this Lease shall be governed by
the laws of the state in which the Premises are located.

9.8 Waiver of Jury Trial. LANDLORD AND TENANT HEREBY IRREVOCABLY AND
UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING
TO THIS LEASE.

9.9 Conveyance by Landlord. The word "Landlord" as used in this Lease means only
the owner for the time being of the Premises, so that, if there is a transfer of
an owner's interest, the transferor shall be and hereby is entirely freed and
relieved of all covenants and obligations of the Landlord hereunder, except any
obligations which accrued prior to the date of transfer, and it shall be deemed
and construed, without further agreement between the parties or between the
parties and the transferee of the Premises, that the transferee has assumed and
has agreed to carry out any and all of the Landlord's covenants and obligation
hereunder from and after the date of transfer.

9.10 Relationship of the Parties. Nothing contained in this Lease shall be
construed in any manner to create any relationship between the Landlord and the
Tenant other than the relationship of landlord and tenant. Without limitation,
the Landlord and the Tenant shall not be considered partners or co-venturers for
any purpose on account of this Lease.

9.11 Representation by Counsel. The Tenant and the Landlord each acknowledge
that it was represented by counsel in connection with the negotiation and
execution of this Lease. This Lease shall not be construed as if it had been
prepared by one of the parties, but rather as if all parties have prepared it.

9.12 Access to Premises. The Tenant will permit the Landlord, any Lender or
prospective Lender or purchaser, and their duly authorized representatives to
enter upon the Premises and to inspect the same at any and all reasonable times,
upon one Business Day advance written notice, and at any time in the case of an
emergency without the giving of notice, and for any purpose reasonably related
to the rights of the Landlord and any Lender under this Lease. Landlord and
Lender shall, in exercising such rights of access, cause no unreasonable
interference with Tenant's business or Tenant's guests. Notwithstanding the
foregoing, Landlord agrees that it will not exercise the foregoing right of
access for the Premises more than once in any calendar year except (a) during
such time as an Event of Default has occurred and is continuing, or (b) in the
event of a sale, financing, refinancing or securitization of any Indenture
relating to the Premises, or (c) if Landlord has reasonable grounds to believe
that the Premises are in violation of Legal Requirements (including
Environmental Laws) or that the Premises are not

                                       37
<PAGE>
being maintained in accordance with the requirements of this Lease or (d) as
otherwise expressly provided in this Lease.

9.13 Showing. During the last 360 days of the Term (or at any time when Tenant
is in default), Landlord, subject to the rights of any subtenant not affiliated
with Tenant, may show the Premises to prospective tenants or purchasers at such
reasonable times during normal business hours as Landlord may select upon one
Business Days prior notice to Tenant, provided that Landlord does not materially
interfere with Tenant's normal business operations.

9.14 True Lease. This Lease is intended as, and shall constitute, an agreement,
of lease, and nothing herein shall be construed as conveying to the Tenant any
right, title or interest in or to the Premises, nor to any remainder or
reversionary estates in the Premises held by any Person, except, in each
instance, as a tenant. Under no circumstances shall this Lease be regarded as an
assignment of all of Landlord's interests in and to the Premises; instead
Landlord and Tenant shall have the relationship between them of landlord and
tenant, pursuant to the provisions of this Lease.

9.15 Landlord's Consent and Standards.

      (a) Whenever Landlord or Lender is allowed or required to give its
consent or approval of any matter under this Lease or to deliver any estoppel or
other instrument, Tenant's sole remedy for such failure to give such consent or
approval or deliver such instrument in accordance with the applicable provision
of this Lease shall be to compel such approval or delivery. In no event and
under no circumstance shall Tenant be entitled to any monetary damages for such
failure or to terminate or otherwise modify this Lease. However, if Tenant shall
bring such an action to compel consent, approval or delivery, the prevailing
party in such action shall be entitled to reimbursement for its reasonable
attorneys' fees; provided, however, that with respect to any attorneys' fees to
be reimbursed by Landlord, such fees and Tenant's right to recover the same
shall be junior and subordinate to an Indenture, and in no event shall Tenant be
entitled to offset any amounts due under this Lease to recover such fees.

      (b) Under no circumstance shall Landlord be deemed to have acted
negligently, grossly negligently or willfully merely by Landlord's ownership of
the Premises, and in no event shall any occurrence relating to the Premises,
whether negligent, grossly negligent or willful, be imputed to Landlord by
reason of Landlord's interest in the Premises, it being understood that all
obligations with respect to the Premises are the responsibility of Tenant under
this Lease. In order to have acted negligently, grossly negligently or
willfully, Landlord must have committed an affirmative act.

9.16 Quiet Enjoyment. Landlord covenants that, so long as Tenant shall
faithfully perform the agreements, terms, and covenants and conditions hereof,
Tenant shall and may peaceably and quietly have, hold and enjoy the

                                       38
<PAGE>
Premises for the term hereby granted without molestation or disturbance by or
from Landlord.

9.17 Force Majeure. The term "Force Majeure" as used in this Lease, shall
mean delays caused by acts of God, strikes and other similar events beyond the
control of Tenant. However, the duration of any delay excused by Force Majeure
shall be limited to the actual amount of time caused by the event giving rise to
the Force Majeure. In addition, no performance by Tenant under this Lease shall
be excused by Force Majeure unless the requirement for performance set forth in
this Lease specifically states that it is subject to Force Majeure.

      IN WITNESS WHEREOF, the parties hereto have caused this Lease to be
executed as of the date first above written.

                                   SCHEDULE F
           DETERMINING FAIR MARKET VALUE FOR REJECTABLE PURCHASE OFFER

If Tenant is required to make a Rejectable Purchase offer under this Lease,
Tenant shall deliver to Landlord at the time of making such Rejectable Purchase
offer, an appraisal of the Premises by an Appraiser. The appraisal shall
calculate the fair market value ("Fair Market Value") as of the date which is
immediately prior to such Condemnation and shall assume that the Premises are
subject to the Lease (and in the condition required to be maintained pursuant to
this Lease), the Lease is in full force and effect, and no condemnation is
pending or threatened.

If Landlord is in agreement with such appraisal, such appraisal shall fix the
Fair Market Value. If Landlord gives Tenant written notice of its disapproval of
the appraisal (to be delivered by Landlord within the twenty (20) days of its
receipt of the appraisal, Fair Market Value shall be determined in accordance
with the following procedure:

Within thirty (30) days after the delivery of notice by Landlord disapproving
Tenant's appraisal, Landlord shall submit to Tenant an appraisal of the
Premises, prepared by an Appraiser; in addition, Landlord's Appraiser and
Tenant's Appraiser shall jointly, within fifteen (15) days after delivery of
notice by Landlord disapproving Tenant's appraisal, choose a third Appraiser who
shall, within thirty days after appointment, choose one of the two appraised
values as the Fair Market Value. The Fair Market Value of the Premises, as
determined by the foregoing procedure, shall be binding upon both Tenant and
Landlord. The fees and expenses of the Appraisers shall be borne by Tenant.

The Appraisers shall not, in making their appraisal of the Premises, attribute
any value to any of Tenant's Personal Property.
